                               EXPLANATION

    The Code of Federal Regulations is a codification of the general and 
permanent rules published in the Federal Register by the Executive 
departments and agencies of the Federal Government. The Code is divided 
into 50 titles which represent broad areas subject to Federal 
regulation. Each title is divided into chapters which usually bear the 
name of the issuing agency. Each chapter is further subdivided into 
parts covering specific regulatory areas.
    Each volume of the Code is revised at least once each calendar year 
and issued on a quarterly basis approximately as follows:

Title 1 through Title 16.................................as of January 1
Title 17 through Title 27..................................as of April 1
Title 28 through Title 41...................................as of July 1
Title 42 through Title 50................................as of October 1

    The appropriate revision date is printed on the cover of each 
volume.

LEGAL STATUS

    The contents of the Federal Register are required to be judicially 
noticed (44 U.S.C. 1507). The Code of Federal Regulations is prima facie 
evidence of the text of the original documents (44 U.S.C. 1510).

HOW TO USE THE CODE OF FEDERAL REGULATIONS

    The Code of Federal Regulations is kept up to date by the individual 
issues of the Federal Register. These two publications must be used 
together to determine the latest version of any given rule.
    To determine whether a Code volume has been amended since its 
revision date (in this case, July 1, 2021), consult the ``List of CFR 
Sections Affected (LSA),'' which is issued monthly, and the ``Cumulative 
List of Parts Affected,'' which appears in the Reader Aids section of 
the daily Federal Register. These two lists will identify the Federal 
Register page number of the latest amendment of any given rule.

EFFECTIVE AND EXPIRATION DATES

    Each volume of the Code contains amendments published in the Federal 
Register since the last revision of that volume of the Code. Source 
citations for the regulations are referred to by volume number and page 
number of the Federal Register and date of publication. Publication 
dates and effective dates are usually not the same and care must be 
exercised by the user in determining the actual effective date. In 
instances where the effective date is beyond the cut-off date for the 
Code a note has been inserted to reflect the future effective date. In 
those instances where a regulation published in the Federal Register 
states a date certain for expiration, an appropriate note will be 
inserted following the text.

OMB CONTROL NUMBERS

    The Paperwork Reduction Act of 1980 (Pub. L. 96-511) requires 
Federal agencies to display an OMB control number with their information 
collection request.

[[Page vi]]

Many agencies have begun publishing numerous OMB control numbers as 
amendments to existing regulations in the CFR. These OMB numbers are 
placed as close as possible to the applicable recordkeeping or reporting 
requirements.

PAST PROVISIONS OF THE CODE

    Provisions of the Code that are no longer in force and effect as of 
the revision date stated on the cover of each volume are not carried. 
Code users may find the text of provisions in effect on any given date 
in the past by using the appropriate List of CFR Sections Affected 
(LSA). For the convenience of the reader, a ``List of CFR Sections 
Affected'' is published at the end of each CFR volume. For changes to 
the Code prior to the LSA listings at the end of the volume, consult 
previous annual editions of the LSA. For changes to the Code prior to 
2001, consult the List of CFR Sections Affected compilations, published 
for 1949-1963, 1964-1972, 1973-1985, and 1986-2000.

``[RESERVED]'' TERMINOLOGY

    The term ``[Reserved]'' is used as a place holder within the Code of 
Federal Regulations. An agency may add regulatory information at a 
``[Reserved]'' location at any time. Occasionally ``[Reserved]'' is used 
editorially to indicate that a portion of the CFR was left vacant and 
not dropped in error.

INCORPORATION BY REFERENCE

    What is incorporation by reference? Incorporation by reference was 
established by statute and allows Federal agencies to meet the 
requirement to publish regulations in the Federal Register by referring 
to materials already published elsewhere. For an incorporation to be 
valid, the Director of the Federal Register must approve it. The legal 
effect of incorporation by reference is that the material is treated as 
if it were published in full in the Federal Register (5 U.S.C. 552(a)). 
This material, like any other properly issued regulation, has the force 
of law.
    What is a proper incorporation by reference? The Director of the 
Federal Register will approve an incorporation by reference only when 
the requirements of 1 CFR part 51 are met. Some of the elements on which 
approval is based are:
    (a) The incorporation will substantially reduce the volume of 
material published in the Federal Register.
    (b) The matter incorporated is in fact available to the extent 
necessary to afford fairness and uniformity in the administrative 
process.
    (c) The incorporating document is drafted and submitted for 
publication in accordance with 1 CFR part 51.
    What if the material incorporated by reference cannot be found? If 
you have any problem locating or obtaining a copy of material listed as 
an approved incorporation by reference, please contact the agency that 
issued the regulation containing that incorporation. If, after 
contacting the agency, you find the material is not available, please 
notify the Director of the Federal Register, National Archives and 
Records Administration, 8601 Adelphi Road, College Park, MD 20740-6001, 
or call 202-741-6010.

CFR INDEXES AND TABULAR GUIDES

    A subject index to the Code of Federal Regulations is contained in a 
separate volume, revised annually as of January 1, entitled CFR Index 
and Finding Aids. This volume contains the Parallel Table of Authorities 
and Rules. A list of CFR titles, chapters, subchapters, and parts and an 
alphabetical list of agencies publishing in the CFR are also included in 
this volume.
    An index to the text of ``Title 3--The President'' is carried within 
that volume.

[[Page vii]]

    The Federal Register Index is issued monthly in cumulative form. 
This index is based on a consolidation of the ``Contents'' entries in 
the daily Federal Register.
    A List of CFR Sections Affected (LSA) is published monthly, keyed to 
the revision dates of the 50 CFR titles.

REPUBLICATION OF MATERIAL

    There are no restrictions on the republication of material appearing 
in the Code of Federal Regulations.

categories of products:
    (1) Automobile and truck air conditioning units (whether 
incorporated in vehicles or not);
    (2) Domestic and commercial refrigeration and air-conditioning/heat 
pump equipment (whether containing controlled substances as a 
refrigerant and/or in insulating material of the product), e.g. 
Refrigerators, Freezers, Dehumidifiers, Water coolers, Ice machines, 
Air-conditioning and heat pump units;
    (3) Aerosol products, except medical aerosols;
    (4) Portable fire extinguishers;
    (5) Insulation boards, panels and pipe covers;

appendix B to this subpart, whether existing alone or in a mixture, but 
excluding any such substance or mixture that is in a manufactured 
product other than a container used for the transportation or storage of 
the substance or mixture. Thus, any amount of a listed substance in 
appendix A or appendix B to this subpart that is not part of a use 
system containing the substance is a controlled substance. If a listed 
substance or mixture must first be transferred from a bulk container to 
another container, vessel, or piece of equipment in order to realize its 
intended use, the listed substance or mixture is a ``controlled 
substance.'' The inadvertent or coincidental creation of insignificant 
quantities of a listed substance in appendix A or appendix B to this 
subpart; during a chemical manufacturing process, resulting from 
unreacted feedstock, from the listed substance's use as a process agent 
present as a trace quantity in the chemical substance being 
manufactured, or as an unintended byproduct of research and development 
applications, is not deemed a controlled substance. Controlled 
substances are divided into two classes, Class I in appendix A to this 
subpart, and Class II listed in appendix B to this subpart. Class I 
substances are further divided into eight groups, Group I, Group II, 
Group III, Group IV, Group V, Group VI, Group VII, and Group VIII, as 
set forth in appendix A to this subpart.

uses.
    Destruction means the expiration of a controlled substance to the 
destruction and removal efficiency actually achieved, unless considered 
completely destroyed as defined in this section. Such destruction might 
result in a commercially useful end product, but such usefulness would 
be secondary to the act of destruction. Destruction must be achieved 
using one of the following controlled processes approved by the Parties 
to the Protocol:
    (1) Liquid injection incineration;
    (2) Reactor cracking;
    (3) Gaseous/fume oxidation;

82.4(n) to produce class I substances, as determined by allocation 
decisions made by the Parties to the Montreal Protocol and in accordance 
with the restrictions delineated in the Clean Air Act Amendments of 
1990.
    Essential-Use Chlorofluorocarbons (Essential-use CFCs) are the CFCs 
(CFC-11, CFC-12, or CFC-114) produced under the authority of essential-
use allowances and not the allowances themselves. Essential-use CFCs

quantities) a controlled substance in the manufacture of other chemicals 
for commercial purposes.
    Transhipment means the continuous shipment of a controlled 
substance, from a foreign state of origin through the United States or 
its territories, to a second foreign state of final destination, as long 
as the shipment does not enter into United States jurisdiction. A 
transhipment, as it moves through the United States or its territories, 
cannot be re-packaged, sorted or otherwise changed in condition.
    Unexpended Article 5 allowances means Article 5 allowances that have 
not been used. At any time in any control period a person's unexpended 
Article 5 allowances are the total of the level of Article 5 allowances 
the person has authorization under this subpart to hold at that time for 
that control period, minus the level of controlled substances that the 
person has produced in that control period until that time.

    Unexpended consumption allowances means consumption allowances that 
have not been used. At any time in any control period a person's 
unexpended consumption allowances are the total of the level of 
consumption allowances the person has authorization under this subpart 
to hold at that time for that control period, minus the level of 
controlled substances that the person has produced or imported (not 
including transhipments and used controlled substances) in that control 
period until that time.
    Unexpended critical use allowances (CUA) means critical use 
allowances against which methyl bromide has not yet been produced or 
imported. At any time in any control period a person's unexpended

controlled substances, and prior to January 1, 2005, for class I, Group 
VI controlled substances, no person may produce, at any time in any 
control period, (except that are transformed or destroyed domestically 
or by a person of another Party) in excess of

[[Page 15]]

the amount of unexpended production allowances or unexpended Article 5 
allowances for that substance held by that person under the authority of 
this subpart at that time for that control period. Every kilogram of 
excess production constitutes a separate violation of this subpart.
    (2) Effective January 1, 2003, production of class I, Group VI 
controlled substances is not subject to the prohibitions in paragraph 
(a)(1) of this section if it is solely for quarantine or preshipment 
applications as defined in this subpart.
    (b)(1) Effective January 1, 1996, for any Class I, Group I, Group 
II, Group III, Group IV, Group V or Group VII controlled substances, and 
effective January 1, 2005 for any Class I, Group VI controlled 
substances, and effective August 18, 2003, for any Class I, Group VIII 
controlled substance, no person may produce, at any time in any control 
period (except that are transformed or destroyed domestically or by a 
person of another Party) in excess of the amount of conferred unexpended 
essential use allowances or exemptions, or in excess of the amount of 
unexpended critical use allowances, or in excess of the amount of 
unexpended Article 5 allowances as allocated under Sec.82.9 and Sec.
82.11, as may be modified under Sec.82.12 (transfer of allowances) for 
that substance held by that person under the authority of this subpart 
at that time for that control period. Every kilogram of excess 
production constitutes a separate violation of this subpart.
    (2) Effective January 1, 2005, production of class I, Group VI 
controlled substances is not subject to the prohibitions in paragraph 
(b)(1) of this section if it is solely for quarantine or preshipment 
applications as defined in this subpart, or it is solely for export to 
satisfy critical uses authorized by the Parties for that control period.
    (c)(1) Prior to January 1, 1996, for all Groups of class I 
controlled substances, and prior to January 1, 2005, for class I, Group 
VI controlled substances, no person may produce or (except for 
transhipments, heels or used controlled substances) import, at any time 
in any control period, (except for controlled substances that are 
transformed or destroyed) in excess of the amount of unexpended 
consumption allowances held by that person under the authority of this 
subpart at that time for that control period. Every kilogram of excess 
production or importation (other than transhipments, heels or used 
controlled substances) constitutes a separate violation of this subpart.
    (2) Effective January 1, 2003, production and import of class I, 
Group VI controlled substances is not subject to the prohibitions in 
paragraph (c)(1) of this section if it is solely for quarantine or 
preshipment applications as defined in this subpart.
    (d) Effective January 1, 1996, for any class I, Group I, Group II, 
Group III, Group IV, Group V, or Group VII controlled substances, and 
effective January 1, 2005, for any class I, Group VI controlled 
substance, and effective August 18, 2003, for any class I, Group VIII 
controlled substance, no person may import (except for transhipments or 
heels), at any time in any control period, (except for controlled 
substances that are transformed or destroyed) in excess of the amount of 
unexpended essential use allowances or exemptions, or in excess of 
unexpended critical use allowances, for that substance held by that 
person under the authority of this subpart at that time for that control 
period. Every kilogram of excess importation (other than transhipments 
or heels) constitutes a separate violation of this subpart. It is a 
violation of this subpart to obtain unused class I controlled substances 
under the general laboratory exemption in excess of actual need and to 
recycle that material for sale into other markets.
    (e) Effective January 1, 1996, no person may place an order by 
conferring essential-use allowances for the production of the class I 
controlled substance, at any time in any control period, in excess of 
the amount of unexpended essential-use allowances, held by that person 
under the authority of this subpart at that time for that control 
period. Effective January 1, 1996, no person may import a class I 
controlled substance with essential-use allowances, at any time in any 
control period, in excess of the amount of unexpended essential-use 
allowances, held by that person under the authority of

[[Page 16]]

this subpart at that time for that control period. No person may import 
or place an order for the production of a class I controlled substance 
with essential-use allowances, at any time in any control period, other 
than for the class I controlled substance(s) for which they received 
essential-use allowances under paragraph (u) of this section. Every 
kilogram of excess production ordered in excess of the unexpended 
essential-use allowances conferred to the producer constitutes a 
separate violation of this subpart. Every kilogram of excess import in 
excess of the unexpended essential-use allowances held at that time 
constitutes a separate violation of this subpart.
    (f) [Reserved]
    (g) Effective January 1, 1996, the U.S. total production and 
importation of a class I controlled substance (except Group VI) as 
allocated under this section for essential-use allowances and 
exemptions, and as obtained under Sec.82.9 for destruction and 
transformation credits, may not, at any time, in any control period 
until January 1, 2000, exceed the percent limitation of baseline 
production in appendix H of this subpart, as set forth in the Clean Air 
Act Amendments of 1990. No person shall cause or contribute to the U.S. 
exceedance of the national limit for that control period.
    (h) No person may sell in the U.S. any Class I controlled substance 
produced explicitly for export to an Article 5 country.
    (i) Effective January 1, 1995, no person may import, at any time in 
any control period, a heel of any class I controlled substance that is 
greater than 10 percent of the volume of the container in excess of the 
amount of unexpended consumption allowances, or unexpended destruction 
and transformation credits held by that person under the authority of 
this subpart at that time for that control period. Every kilogram of 
excess importation constitutes a separate violation of this subpart.
    (j)(1) Effective January 1, 1995, no person may import, at any time 
in any control period, a used class I controlled substance, except for 
Group II used controlled substances shipped in aircraft halon bottles 
for hydrostatic testing, without having received a non-objection notice 
from the Administrator in accordance with Sec.82.13(g)(2) and (3). A 
person who receives a non-objection notice for the import of an 
individual shipment of used controlled substances may not transfer or 
confer the right to import and may not import any more than the exact 
quantity, in kilograms, of the used controlled substance cited in the 
non-objection notice. Every kilogram of importation of used controlled 
substance in excess of the quantity cited in the non-objection notice 
issued by the Administrator in accordance with Sec.82.13(g)(2) and (3) 
constitutes a separate violation.
    (2) No person may import for purposes of destruction, at any time in 
any control period, a class I controlled substance for which EPA has 
apportioned baseline production and consumption allowances, without 
having submitted a certification of intent to import for destruction to 
the Administrator and received a non-objection notice in accordance with 
Sec.82.13(g)(5). A person issued a non-objection notice for the import 
of an individual shipment of class I controlled substances for 
destruction may not transfer or confer the right to import and may not 
import any more than the exact quantity (in kilograms) of the class I 
controlled substance stated in the non-objection notice. For imports 
intended to be destroyed in the United States, a person issued a non-
objection notice must destroy the controlled substance within one year 
of the date stamped on the non-objection letter, may not transfer or 
confer the right to import, and may not import any more than the exact 
quantity (in kilograms) of the class I controlled substance stated in 
the non-objection notice. Every kilogram of import of class I controlled 
substance in excess of the quantity stated in the non-objection notice 
issued by the Administrator in accordance with Sec.82.13(g)(5) 
constitutes a separate violation of this subpart.
    (k)(1) Prior to January 1, 1996, for all Groups of class I 
controlled substances, and prior to January 1, 2005, for class I, Group 
VI controlled substances, a person may not use production allowances to 
produce a quantity of a class I controlled substance unless that person

[[Page 17]]

holds under the authority of this subpart at the same time consumption 
allowances sufficient to cover that quantity of class I controlled 
substances nor may a person use consumption allowances to produce a 
quantity of class I controlled substances unless the person holds under 
authority of this subpart at the same time production allowances 
sufficient to cover that quantity of class I controlled substances. 
However, prior to January 1, 1996, for all class I controlled 
substances, and prior to January 1, 2005, for class I, Group VI 
controlled substances, only consumption allowances are required to 
import, with the exception of transhipments, heels, and used controlled 
substances. Effective January 1, 1996, for all Groups of class I 
controlled substances, except Group VI, only essential use allowances or 
exemptions are required to import class I controlled substances, with 
the exception of transhipments, heels, used controlled substances, and 
essential use CFCs.
    (2) Notwithstanding paragraph (k)(1) of this section, effective 
January 1, 2003, for class I, Group VI controlled substances, 
consumption allowances are not required to import quantities solely for 
quarantine or preshipment applications as defined in this subpart.
    (l) Every kilogram of a controlled substance, and every controlled 
product, imported or exported in contravention of this subpart 
constitutes a separate violation of this subpart. No person may:
    (1) Import or export any quantity of a controlled substance listed 
in class I, Group I or Group II, in appendix A to this subpart from or 
to any foreign state not Party to the 1987 Montreal Protocol unless that 
foreign state is complying with the 1987 Montreal Protocol (For 
ratification status, see: http://ozone.unep.org/new_site/en/
treaty_ratification_status.php);
    (2) Import or export any quantity of a controlled substance listed 
in class I, Group III, Group IV, or Group V, in appendix A to this 
subpart, from or to any foreign state not Party to the London Amendment, 
unless that foreign state is complying with the London Amendment (For 
ratification status, see: http://ozone.unep.org/new_site/en/
treaty_ratification_status.php); or
    (3) Import a controlled product, as noted in appendix D, annex 1 to 
this subpart, from any foreign state not Party to the 1987 Montreal 
Protocol, unless that foreign state is complying with the 1987 Montreal 
Protocol (For ratification status, see: http://ozone.unep.org/new_site/
en/treaty_ratification_status.php).
    (4) Import or export any quantity of a controlled substance listed 
in class I, Group VII, in appendix A to this subpart, from or to any 
foreign state not Party to the Copenhagen Amendment, unless that foreign 
state is complying with the Copenhagen Amendment (For ratification 
status, see: http://ozone.unep.org/new_site/en/
treaty_ratification_status.php).
    (5) Import or export any quantity of a controlled substance listed 
in class I, Group VI, in appendix A to this subpart, from or to any 
foreign state not Party to the Copenhagen Amendment unless that foreign 
state is complying with the Copenhagen Amendment (For ratification 
status, see: http://ozone.unep.org/new_site/en/
treaty_ratification_status.php).
    (6) Import or export any quantity of a controlled substance listed 
in class I, Group VIII, in appendix A to this subpart, from or to any 
foreign state not Party to the Beijing Amendment, unless that foreign 
state is complying with the Beijing Amendment (For ratification status, 
see: http://ozone.unep.org/new_site/en/treaty_ratification_status.php).
    (m) Effective October 5, 1998, no person may export a controlled 
product to a Party listed in appendix J of this subpart in any control 
period after the control period in which EPA publishes a notice in the 
Federal Register listing that Party in appendix J of this subpart. EPA 
will publish a notice in the Federal Register that lists a Party in 
appendix J if the Party formally presents to the U.S. a government 
document through its embassy in the United States stating that it has 
established a ban on the import of controlled products and a ban on the 
manufacture of those same controlled products.

[[Page 18]]

    (n) No person may use class I controlled substances produced or 
imported under the essential use exemption for any purpose other than 
those set forth in this paragraph. Effective January 1, 1996, essential-
use allowances are apportioned to a person under Sec.82.8(a) and (b) 
for the exempted production or importation of specified class I 
controlled substances solely for the purposes listed in paragraphs 
(n)(1)(i) through (iii) of this section.
    (1) Essential-uses for the production or importation of controlled 
substances as agreed to by the Parties to the Protocol and subject to 
the periodic revision of the Parties are:
    (i) Metered dose inhalers (MDIs) for the treatment of asthma and 
chronic obstructive pulmonary disease that were approved by the Food and 
Drug Administration before December 31, 2000.
    (ii) Space Shuttle--solvents.
    (iii) Essential laboratory and analytical uses (defined in appendix 
G of this subpart).
    (2) Any person acquiring unused class I controlled substances 
produced or imported under the authority of essential-use allowances or 
the essential-use exemption granted in Sec.82.8 to this subpart for 
use in anything other than an essential-use (i.e., for uses other than 
those specifically listed in paragraph (n)(1) of this section) is in 
violation of this subpart. Each kilogram of unused class I controlled 
substance produced or imported under the authority of essential-use 
allowances or the essential-use exemption and used for a non-essential 
use is a separate violation of this subpart. Any person selling unused 
class I controlled substances produced or imported under authority of 
essential-use allowances or the essential-use exemption for uses other 
than an essential-use is in violation of this subpart. Each kilogram of 
unused class I controlled substances produced or imported under 
authority of essential-use allowances or the essential-use exemption and 
sold for a use other than an essential-use is a separate violation of 
this subpart. It is a violation of this subpart to obtain unused class I 
controlled substances under the exemption for laboratory and analytical 
uses in excess of actual need and to recycle that material for sale into 
other markets.
    (o) [Reserved]
    (p) Critical Use Exemption: With respect to class I, Group VI 
substances (methyl bromide):
    (1) No person shall sell critical use methyl bromide without first 
receiving a certification from the purchaser that the quantity purchased 
will be sold or used solely for an approved critical use. Every kilogram 
of critical use methyl bromide sold without first obtaining such 
certification constitutes a separate violation of this subpart.
    (2) For approved critical users, each action associated with each 
200 kilograms of critical use methyl bromide for the following 
subparagraphs constitutes a separate violation of this subpart.
    (i) No person shall take possession of quantities of critical use 
methyl bromide or acquire fumigation services using quantities of 
critical use methyl bromide without first completing the appropriate 
certification in accordance with the requirements in Sec.82.13.
    (ii) No person who purchases critical use methyl bromide may use 
such quantities for a use other than the specified critical use listed 
in column A and the specified location of use in column B of appendix L 
to this subpart.
    (iii) No person who purchases critical use methyl bromide produced 
or imported with expended critical use allowances for pre-plant uses, 
may use such quantities for other than the pre-plant uses as specified 
in column A and column B of appendix L to this subpart.
    (iv) No person who purchases critical use methyl bromide produced or 
imported with expended critical use allowances for post-harvest uses, 
may use such quantities for other than the post-harvest uses as 
specified in column A and column B of appendix L to this subpart.
    (v) No person who uses critical use methyl bromide on a specific 
field or structure may concurrently or subsequently use non-critical use 
methyl bromide on the same field or structure for the same use (as 
defined in column A and column B of appendix L) in the same control 
period, excepting methyl

[[Page 19]]

bromide used under the quarantine and pre-shipment exemption.
    (vi) No person who purchases critical use methyl bromide during the 
control period shall use that methyl bromide on a field or structure for 
which that person has used non-critical use methyl bromide for the same 
use (as defined in columns A and B of appendix L) in the same control 
period, excepting methyl bromide used under the quarantine and pre-
shipment exemption, unless, subsequent to that person's use of the non-
critical use methyl bromide, that person becomes subject to a 
prohibition on the use of methyl bromide alternatives due to the 
reaching of a local township limit described in appendix L of this part, 
or becomes an approved critical user as a result of rulemaking.
    (q) Emergency use exemption. [Reserved]
    (r) No person may sell or use methyl bromide produced or imported 
under the quarantine and preshipment exemption for any purpose other 
than for quarantine applications or preshipment applications as defined 
in Sec.82.3. Each kilogram of methyl bromide produced or imported 
under the authority of the quarantine and preshipment exemption and sold 
or used for a use other than quarantine or preshipment is a separate 
violation of this subpart.
    (s) No person may sell or distribute, or offer for sale or 
distribution, any class I substance that they know, or have reason to 
know, was imported in violation of this section, except for such actions 
needed to re-export the controlled substance. Every kilogram of a 
controlled substance imported in contravention of this paragraph (s) 
that is sold or distributed, or offered for sale or distribution, 
constitutes a separate violation of this subpart.

Sec.82.9  Availability of production allowances in addition to
baseline production allowances for class I controlled substances.

    (a)--(b) [Reserved]
    (c) A company may increase or decrease its production allowances, 
including its Article 5 allowances, by trading with another Party to the 
Protocol according to the provision under this paragraph (c). A company 
may increase or decrease its essential-use allowances for CFCs for use 
in essential MDIs according to the provisions under this paragraph (c). 
A nation listed in appendix C to this subpart (Parties to the Montreal 
Protocol) must agree either to transfer to the person for the current 
control period some amount of production or import that the nation is 
permitted under the Montreal Protocol or to receive from the person for 
the current control period some amount of production or import that the 
person is permitted under this subpart. If the controlled substance is 
produced under the authority of production allowances and is to be sold 
in the United States

[[Page 24]]

or to another Party (not the Party from whom the allowances are 
received), the U.S. company must expend its consumption allowances 
allocated under Sec. Sec.82.6 and 82.7 in order to produce with the 
additional production allowances.
    (1) For trades from a Party, the person must obtain from the 
principal diplomatic representative in that nation's embassy in the 
United States a signed document stating that the appropriate authority 
within that nation has established or revised production limits or 
essential-use allowance limits for the nation to equal the lesser of the 
maximum production that the nation is allowed under the Protocol minus 
the amount transferred, the maximum production or essential-use 
allowances that are allowed under the nation's applicable domestic law 
minus the amount transferred, or the average of the nation's actual 
national production level for the three years prior to the transfer 
minus the production transferred. The person must submit to the 
Administrator a transfer request that includes a true copy of this 
document and that sets forth the following:
    (i) The identity and address of the person;
    (ii) The identity of the Party;
    (iii) The names and telephone numbers of contact persons for the 
person and for the Party;
    (iv) The chemical type, type of allowance being transferred, and the 
level of allowances being transferred;
    (v) The control period(s) to which the transfer applies; and
    (vi) For increased production intended for export to the Party from 
whom the allowances would be received, a signed statement of intent to 
export to the Party.
    (vii) In the case of transferring essential-use allowances, the 
transferor must include a signed document from the transferee 
identifying the CFC MDI products that will be produced using the 
essential-use allowances.
    (2) For trades to a Party, a person must submit a transfer request 
that sets forth the following:
    (i) The identity and address of the person;
    (ii) The identity of the Party;
    (iii) The names and telephone numbers of contact persons for the 
person and for the Party;
    (iv) The chemical type, type of allowance being transferred, and the 
level of allowances being transferred; and
    (v) The control period(s) to which the transfer applies.
    (3) After receiving a transfer request that meets the requirements 
of paragraph (c)(2) of this section, the Administrator may, at his 
discretion, consider the following factors in deciding whether to 
approve such a transfer:
    (i) Possible creation of economic hardship;
    (ii) Possible effects on trade;
    (iii) Potential environmental implications; and
    (iv) The total amount of unexpended production or essential-use 
allowances held by a U.S. entity.
    (v) In the case of transfer of essential-use allowances the 
Administrator may consider whether the CFCs will be used for production 
of essential MDIs.
    (4) The Administrator will issue the person a notice either granting 
or deducting production allowances, Article 5 allowances, or essential-
use allowances, and specifying the control period to which the transfer 
applies, provided that the request meets the requirement of paragraph 
(c)(1) of this sections for trades from Parties and paragraph (c)(2) of 
this section for trades to Parties, unless the Administrator has decided 
to disapprove the trade under paragraph (c)(3) of this section. For a 
trade from a Party, the Administrator will issue a notice that revises 
the allowances held by the person to equal the unexpended production, 
Article 5, or essential-use allowances held by the person under this 
subpart plus the level of allowable production transferred from the 
Party. For a trade to a Party, the Administrator will issue a notice 
that revises the production limit for the person to equal the lesser of:
    (i) The unexpended production allowances, essential-use allowances, 
or Article 5 allowances held by the person under this subpart minus the 
amount transferred; or
    (ii) The unexpended production allowances, essential-use allowances, 
or Article 5 allowances held by the person

[[Page 25]]

under this subpart minus the amount by which the United States average 
annual production of the controlled substance being traded for the three 
years prior to the transfer is less than the total production allowable 
for that substance under this subpart minus the amount transferred. The 
change in allowances will be effective on the date that the notice is 
issued.
    (5) If after one person obtains approval for a trade of allowable 
production of a controlled substance to a Party, one or more other 
persons obtain approval for trades involving the same controlled 
substance and the same control period, the Administrator will issue 
notices revising the production limits for each of the other persons 
trading that controlled substance in that control period to equal the 
lesser of:
    (i) The unexpended production allowances or Article 5 allowances 
held by the person under this subpart minus the amount transferred; or
    (ii) The unexpended production allowances or Article 5 allowances 
held by the person under this subpart minus the amount by which the 
United States average annual production of the controlled substance 
being traded for the three years prior to the transfer is less than the 
total allowable production for that substance under this subpart 
multiplied by the amount transferred divided by the total amount 
transferred by all the other persons trading the same controlled 
substance in the same control period minus the amount transferred by 
that person.
    (iii) The Administrator will also issue a notice revising the 
production limit for each person who previously obtained approval of a 
trade of that substance in that control period to equal the unexpended 
production allowances or unexpended Article 5 allowances held by the 
person under this subpart plus the amount by which the United States 
average annual production of the controlled substance being traded for 
the three years prior to the transfer is less than the total allowable 
production under this subpart multiplied by the amount transferred by 
that person divided by the amount transferred by all of the persons who 
have traded that controlled substance in that control period. The change 
in production allowances or Article 5 allowances will be effective on 
the date that the notice is issued.
    (d) Effective January 1, 1996, there will be no trade in production 
or consumption allowances with other Parties to the Protocol for class I 
controlled substances, except for class I, Group VI, methyl bromide.
    (e)--(f) [Reserved]
    (g) International transfer of essential-use CFCs. (1) For trades of 
essential-use CFCs where the transferee or the transferor is a person in 
another nation (Party), the persons involved in the transfer must submit 
the information requested in Sec.82.12(d)(2) and (d)(3), along with a 
signed document from the principal diplomatic representative in the 
Party's embassy in the United States stating that the appropriate 
authority within that nation has approved the transfer of the essential-
use CFCs.
    (2) If the transfer claim is complete, and EPA does not object to 
the transfer, then EPA will issue letters to the transferor and the 
transferee indicating that the transfer may proceed. EPA reserves the 
right to disallow a transfer if the transfer request is incomplete, or 
if it has reason to believe that the transferee plans to produce MDIs 
that are not essential MDIs. If EPA objects to the transfer, EPA will 
issue letters to the transferor and transferee stating the basis for 
disallowing the transfer. The burden of proof is placed on the 
transferee to retain sufficient records to prove that the transferred 
essential-use CFCs are used only for production of essential MDIs. If 
EPA ultimately finds that the transferee did not use the essential-use 
CFCs for production of essential MDIs then the transferee is in 
violation of this subpart.

    (D) The group of controlled substances to which the allowances being 
transferred pertains;
    (E) The amount of allowances being transferred;
    (F) The control period(s) for which the allowances are being 
transferred;
    (G) The amount of unexpended allowances of the type and for the 
control period being transferred that the transferor holds under 
authority of this subpart as of the date the claim is submitted to EPA; 
and
    (H) The one percent offset applied to the unweighted amount traded 
will be deducted from the transferor's production or consumption 
allowance balance (except for trades from transformers and destroyers to 
producers or importers for the purpose of allowance reimbursement). In 
the case of transferring essential use allowances, the amount of one 
tenth of one percent of the amount traded will be deducted from the 
transferor's allowance balance. In the case of transferring critical use 
allowances, the amount of one tenth of one percent of the amount traded 
will be deducted from the transferor's critical use allowance balance.
    (I) The transferor must include a signed document from the 
transferee identifying the CFC MDI products that will be produced using 
the essential-use allowances.
    (ii) The Administrator will determine whether the records maintained 
by EPA, taking into account any previous transfers and any production, 
allowable imports and exports of controlled substances reported by the 
transferor, indicate that the transferor possesses, as of the date the 
transfer claim is processed, unexpended allowances sufficient to cover 
the transfer claim (i.e., the amount to be transferred plus, in the case 
of transferors of essential use allowances and critical use allowances, 
one tenth of one percent of the transferred amount). Within three 
working days of receiving a complete transfer claim, the Administrator 
will take action to notify the transferor and transferee as follows:
    (A) If EPA's records show that the transferor has sufficient 
unexpended allowances to cover the transfer claim, the Administrator 
will issue a notice indicating that EPA does not object to the transfer 
and will reduce the transferor's balance of unexpended allowances by the 
amount to be transferred plus, in the case of transfers of production or 
consumption allowances, one percent of that amount, or in the case of 
transfers of essential use allowances, one tenth of one percent of that 
amount. When EPA issues a no objection notice, the transferor and the 
transferee may proceed with the transfer. However, if EPA ultimately 
finds that the transferor did not have sufficient unexpended allowances 
to cover the claim, the transferor and transferee will be held liable 
for any violations of the regulations of this subpart that occur as a 
result of, or in conjunction with, the improper transfer.
    (B) If EPA's records show that the transferor has insufficient 
unexpended allowances to cover the transfer claim, or that the 
transferor has failed to respond to one or more Agency requests to 
supply information needed to make a determination, the Administrator 
will issue a notice disallowing the transfer. Within 10 working days 
after receipt of notification, either party may file a notice of appeal, 
with supporting reasons, with the Administrator. The Administrator may 
affirm or vacate the disallowance. If no appeal is taken by the tenth 
working day after notification, the disallowance shall be final on that 
day.

[[Page 28]]

    (iii) In the event that the Administrator does not respond to a 
transfer claim within the three working days specified in paragraph 
(a)(1)(ii) of this section the transferor and transferee may proceed 
with the transfer. EPA will reduce the transferor's balance of 
unexpended allowances by the amount to be transferred plus, in the case 
of transfers of production or consumption allowances, one percent of 
that amount, and in the case of essential use allowances and critical 
use allowances, one tenth of one percent of that amount. However if EPA 
ultimately finds that the transferor did not have sufficient unexpended 
allowances to cover the claim, the transferor and transferee will be 
held liable for any violations of the regulations of this subpart that 
occur as a result of, or in conjunction with, the improper transfer.
    (2) [Reserved]
    (b)--(c) [Reserved]
    (d) Transfers of essential-use CFCs. (1) Effective January 1, 2002, 
any metered dose inhaler company (transferor) may transfer essential-use 
CFCs to another metered dose inhaler company (transferee) provided that 
the Administrator approves the transfer.
    (2) The transferee must submit a transfer claim to the Administrator 
for approval before the transfer can take place. The transfer claim must 
set forth the following:
    (i) The identities and addresses of the transferor and the 
transferee; and
    (ii) The name and telephone numbers of contact persons for the 
transferor and the transferee; and
    (iii) The amount of each controlled substance (CFC-11, CFC-12, or 
CFC-114) being transferred; and
    (iv) The specific metered dose inhaler products (i.e. the MDI drug 
product or active moiety) that the transferee plans to produce with the 
transferred CFCs; and
    (v) The country(ies) where the CFC metered dose inhalers produced 
with the transferred essential-use CFCs will be sold if other than in 
the United States; and
    (vi) Certification that the essential-use CFCs will be used in the 
production of essential MDIs. If the MDIs are to be sold in the United 
States, the certification must state that MDIs produced with the 
transferred essential-use CFCs are listed as essential at 21 CFR 2.125, 
and were approved by the Food and Drug Administration before December 
31, 2000. If the MDIs produced with the essential-use CFCs are to be 
sold outside the United States, the transferee must certify that the 
metered dose inhalers produced with the essential-use CFCs are 
considered essential by the importing country.
    (3) The transferor must submit a letter stating that it concurs with 
the terms of the transfer as requested by the transferee.
    (4) Once the transfer claim is complete, and if EPA does not object 
to the transfer, then EPA will issue letters to the transferor and the 
transferee within 10 business days indicating that the transfer may 
proceed. EPA reserves the right to disallow a transfer if the transfer 
request is incomplete, or if it has reason to believe that the 
transferee plans use the essential-use CFCs in anything other than 
essential MDIs. If EPA objects to the transfer, within EPA will issue 
letters to the transferor and transferee stating the basis for 
disallowing the transfer. The burden of proof is placed on the 
transferee to retain sufficient records to prove that the transferred 
essential-use CFCs are used only for production of essential MDIs. If 
EPA ultimately finds that the transferee did not use the essential-use 
CFCs for production of essential MDIs then the transferee is in 
violation of this subpart.

[[Page 34]]

    (xv) If the used controlled substance is stored in a halon bank, in 
lieu of the information required in paragraphs (g)(2)(iv) through (vi) 
of this section, the petitioner may provide an official letter from the 
appropriate government agency in the country where the material is 
stored indicating that the halon is used and that the halon bank is 
authorized to collect used halon. If source information in paragraphs 
(g)(2)(iv) through (vi) is available, it should also be provided in 
addition to the letter.
    (3) Review of petition to import a used substance. Starting on the 
first working day following receipt by the Administrator of a petition 
to import a used class I controlled substance, the Administrator will 
initiate a review of the information submitted under paragraph (g)(2) of 
this section and take action within 40 working days to issue either an 
objection-notice or a non-objection notice for the individual shipment 
to the person who submitted the petition to import the used class I 
controlled substance.
    (i) For the following reasons, the Administrator may issue an 
objection notice to a petition:
    (A) If the Administrator determines that the information is 
insufficient, that is, if the petition lacks or appears to lack any of 
the information required under paragraph (g)(2) of this section or other 
information that may be requested during the review of the petition 
necessary to verify that the controlled substance is used;
    (B) If the Administrator determines that any portion of the petition 
contains false or misleading information, or the Administrator has 
information from other U.S. or foreign government agencies indicating 
that the petition contains false or misleading information;
    (C) If the importer wishes to import a used class I controlled 
substance from a country which is, for that particular controlled 
substance, out of compliance regarding its phaseout obligations under 
the Protocol or the transaction in the petition is contrary to other 
provisions in the Vienna Convention or the Montreal Protocol;
    (D) If the appropriate government agency in the exporting country 
has not agreed to issue an export license for the cited individual 
shipment of used controlled substance;
    (E) If allowing the import of the used class I controlled substance 
would run counter to government restrictions from either the country of 
recovery or export regarding controlled ozone-depleting substances;
    (F) If reclamation capacity is installed or is being installed for 
that specific controlled substance in the country of recovery or country 
of export and the capacity is funded in full or in part through the 
Multilateral Fund.
    (ii) Within ten (10) working days after receipt of the objection 
notice, the importer may re-petition the Administrator, only if the 
Administrator indicated ``insufficient information'' as the basis for 
the objection notice. If no appeal is taken by the tenth working day 
after the date on the objection notice, the objection shall become 
final. Only one appeal of re-petition will be accepted for any petition 
received by EPA.
    (iii) Any information contained in the re-petition which is 
inconsistent with the original petition must be identified and a 
description of the reason for the inconsistency must accompany the re-
petition.
    (iv) In cases where the Administrator does not object to the 
petition based on the criteria listed in paragraph (g)(3)(i) of this 
section, the Administrator will issue a non-objection notice.
    (v) To pass the approved used class I controlled substances through 
U.S. Customs, the non-objection notice issued by EPA must accompany the 
shipment through U.S. Customs.
    (vi) If for some reason, following EPA's issuance of a non-objection

Sec.82.15  Prohibitions for class II controlled substances.

    (a) Production. (1) Effective January 21, 2003, no person may 
produce class II controlled substances for which EPA has apportioned 
baseline production and consumption allowances, in excess of the 
quantity of unexpended production allowances, unexpended Article 5 
allowances, unexpended export production allowances, or conferred 
unexpended HCFC-141b exemption allowances held by that person for that 
substance under the authority of this subpart at that time in that 
control period, unless the substances are transformed or destroyed 
domestically or by a person of another Party, or unless they are 
produced using an exemption granted in paragraph (f) of this section. 
Every kilogram of excess production constitutes a separate violation of 
this subpart.
    (2) Effective January 21, 2003, no person may use production 
allowances to produce a quantity of class II controlled substance unless 
that person holds under the authority of this subpart at the same time 
consumption allowances sufficient to cover that quantity of class II 
controlled substances. No person may use consumption allowances to 
produce a quantity of class II controlled substances unless the person 
holds under authority of this subpart at the same time production 
allowances sufficient to cover that quantity of class II controlled 
substances.
    (b) Import. (1) Effective January 21, 2003, no person may import 
class II controlled substances (other than transhipments, heels or used 
class II controlled substances) for which EPA has apportioned baseline 
production and consumption allowances , in excess of the quantity of 
unexpended consumption allowances, or conferred unexpended HCFC-141b 
exemption allowances held by that person under the authority of this 
subpart at that time in that control period, unless the substances are 
for use in a process resulting in their transformation or their 
destruction, or unless they are produced using an exemption granted in 
paragraph (f) of this section. Every kilogram of excess import 
constitutes a separate violation of this subpart.
    (2) Effective January 21, 2003, no person may import, at any time in 
any control period, a used class II controlled substance for which EPA 
has apportioned baseline production and consumption allowances, without 
having submitted a petition to the Administrator and received a non-
objection notice in accordance with Sec.82.24(c)(3) and (4). A person 
issued a non-objection notice for the import of an individual shipment 
of used class II controlled substances may not transfer or confer the 
right to import, and may not import any more than the exact quantity (in 
kilograms) of the used class II controlled substance stated in the non-
objection notice. Every kilogram of import of used class II controlled 
substance in excess of the quantity stated in the non-objection notice 
issued by the Administrator in accordance with Sec.82.24(c)(3) and (4) 
constitutes a separate violation of this subpart.
    (3) No person may import for purposes of destruction, at any time in 
any control period, a class II controlled substance for which EPA has 
apportioned baseline production and consumption allowances, without 
having submitted a certification of intent to import for destruction to 
the Administrator and received a non-objection notice in accordance with 
Sec.82.24(c)(6). A person issued a non-objection notice for the import 
of an individual shipment of class II controlled substances

[[Page 44]]

for destruction may not transfer or confer the right to import and may 
not import any more than the exact quantity (in kilograms) of the class 
II controlled substance stated in the non-objection notice. For imports 
intended to be destroyed in the United States, a person issued a non-
objection notice must destroy the controlled substance within one year 
of the date stamped on the non-objection letter, may not transfer or 
confer the right to import, and may not import any more than the exact 
quantity (in kilograms) of the class II controlled substance stated in 
the non-objection notice. Every kilogram of import of class II 
controlled substance in excess of the quantity stated in the non-
objection notice issued by the Administrator in accordance with Sec.
82.24(c)(6) constitutes a separate violation of this subpart.
    (c) Production with Article 5 allowances. No person may introduce 
into U.S. interstate commerce any class II controlled substance produced 
with Article 5 allowances, except for export to an Article 5 Party as 
listed in Appendix E of this subpart. Every kilogram of a class II 
controlled substance produced with Article 5 allowances that is 
introduced into interstate commerce other than for export to an Article 
5 Party constitutes a separate violation under this subpart. No person 
may export any class II controlled substance produced with Article 5 
allowances to a non-Article 5 Party. Every kilogram of a class II 
controlled substance that was produced with Article 5 allowances that is 
exported to a non-Article 5 Party constitutes a separate violation under 
this subpart.
    (d) Production with export production allowances. No person may 
introduce into U.S. interstate commerce any class II controlled 
substance produced with export production allowances. Every kilogram of 
a class II controlled substance that was produced with export production 
allowances that is introduced into U.S. interstate commerce constitutes 
a separate violation under this subpart.
    (e) Trade with Parties. No person may import or export any quantity 
of a class II controlled substance listed in Appendix A to this subpart, 
from or to any foreign state that is not either:
    (1) A Party to the Beijing Amendment. As of March 14, 2014, the 
following foreign states had not ratified the Beijing Amendment: 
Kazakhstan, Libya, and Mauritania. For updates on ratification status, 
see the Ozone Secretariat's Web site at: http://ozone.unep.org/new_site/
en/treaty_ratification_status.php. Or,
    (2) A foreign state not party to the Beijing Amendment that is 
complying with the Beijing Amendment as defined in this subpart.

section.
    (2) [Reserved]
    (c) International trades of production allowances, export production 
allowances and Article 5 allowances. (1) A person may increase or 
decrease their production allowances, export production allowances, or 
Article 5 allowances, for a specified control period through trades with 
a foreign state that is Party to the Beijing Amendment or is complying 
with the Beijing Amendment as defined in this subpart. The foreign state 
must agree either to trade to the person for the current control period 
some quantity of production that the foreign state is permitted under 
the Montreal Protocol or to receive from the person for the current 
control period some quantity of production that the person is permitted 
under this subpart. The person must expend their consumption allowances 
allocated under Sec.82.19, or obtained under Sec.82.20 in order to 
produce with the additional production allowances.
    (2) Trade from a Party--Information requirements. (i) A person 
requesting a trade from a Party must submit to the Administrator a 
signed document from the principal diplomatic representative in that 
nation's embassy in the U.S. stating that the appropriate authority 
within that nation will establish or revise production limits for the 
nation to equal the lowest of the following three production quantities:
    (A) The maximum production that the nation is allowed under the 
Protocol minus the quantity (in kilograms) to be traded;
    (B) The maximum production that is allowed under the nation's 
applicable domestic law minus the quantity (in kilograms) to be traded; 
or
    (C) The average of the nation's actual national production level for 
the three years prior to the trade minus the production to be traded.
    (ii) A person requesting a trade from a Party must also submit to 
the Administrator a true copy of the document that sets forth the 
following:
    (A) The identity and address of the person;
    (B) The identity of the Party;
    (C) The names and telephone numbers of contact persons for the 
person and for the Party;
    (D) The chemical type and quantity (in kilograms) of production 
being traded;
    (E) Documentation that the Party possesses the necessary quantity of 
unexpended production rights;
    (F) The control period(s) to which the trade applies; and
    (G) For increased production intended for export to the Party from 
whom the allowances would be received, a signed statement of intent to 
export to the Party.
    (3) Trade to a Party--Information requirements. A person requesting 
a trade to a Party must submit a request that sets forth the following 
information to the Administrator:
    (i) The identity and address of the person;
    (ii) The identity of the Party;
    (iii) The names and telephone numbers of contact persons for the 
person and for the Party;
    (iv) The chemical type and quantity (in kilograms) of allowable 
production being traded; and
    (v) The control period(s) to which the trade applies.
    (4) Review of international trade request to a Party. After 
receiving a trade request that meets the requirements of

[[Page 52]]

paragraph (c)(3) of this section, the Administrator may, at his/her 
discretion, consider the following factors by seeking concurrence from 
the Department of Commerce, the United States Trade Representative, and 
the Department of State, where appropriate, in deciding whether to 
approve such a trade:
    (i) Possible creation of domestic economic hardship;
    (ii) Possible effects on trade;
    (iii) Potential environmental implications; and
    (iv) The total quantity of unexpended production allowances held by 
U.S. entities.
    (5) Notice of trade. If the request meets the requirement of 
paragraph (c)(2) of this section for trades from Parties and paragraphs 
(c)(3) and (4) of this section for trades to Parties, the Administrator 
will issue the person a notice. The notice will either grant or deduct 
production allowances or export production allowances or Article 5 
allowances and specify the control period to which the trade applies. 
The Administrator may disapprove the trade request contingent on the 
consideration of factors listed in paragraph (c)(4) of this section for 
trades to Parties.
    (i) For trades from a Party, the Administrator will issue a notice 
revising the allowances held by the recipient of the trade to equal the 
unexpended production allowances, unexpended export production 
allowances, or unexpended Article 5 allowances held by the recipient of 
the trade under this subpart plus the quantity of allowable production 
traded from the Party.
    (ii) For trades to a Party, the Administrator will issue a notice 
revising the production limit for the trader to equal the lesser of:
    (A) The unexpended production allowances, unexpended export 
production allowances or unexpended Article 5 allowances held by the 
trade or minus the quantity traded; or
    (B) The unexpended production allowances held by the trader minus 
the amount by which the U.S. average annual production of the class II 
controlled substance being traded for the three years prior to the trade 
is less than the total allowable production of that class II controlled 
substance under this subpart minus the amount traded; or
    (C) The total U.S. allowable production of the class II controlled 
substance being traded minus the three-year average of the actual annual 
U.S. production of the class II controlled substance prior to the 
control period of the trade.
    (6) Revised notices of production limits for subsequent traders. If 
after one person obtains approval of a trade of allowable production of 
a class II controlled substance to a Party and other persons obtain 
approval for trades of the same class II controlled substance during the 
same control period, the Administrator will issue revised notices. The 
notices will revise the production limits for each of the other persons 
trading to equal the lesser of:
    (i) The unexpended production allowances, unexpended export 
production allowances or unexpended Article 5 allowances held by the 
trader under this subpart minus the quantity traded; or
    (ii) The result of the following set of calculations:
    (A) The total U.S. allowable production of the class II controlled 
substance minus the three-year average of the actual annual U.S. 
production of the class II controlled substance prior to the control 
period of the trade;
    (B) The quantity traded divided by the total quantity traded by all 
the other persons trading the same class II controlled substance in the 
same control period;
    (C) The result of paragraph (c)(6)(ii)(A) of this section multiplied 
by the result of paragraph (c)(6)(ii)(B) of this section;
    (D) The quantity derived in paragraph (c)(6)(i) of this section, 
minus the result of paragraph (c)(6)(ii)(C) of this section;
    (7) Production limit for previous traders. The Administrator will 
also issue a notice revising the production limit for each trader who 
previously obtained approval of a trade of the class II controlled 
substance to a Party in the same control period to equal the result of 
the following set of calculations:
    (i) The total U.S. allowable production of the class II controlled 
substance minus the three-year average of the actual annual U.S. 
production of the

[[Page 53]]

class II controlled substance prior to the control period of the trade;
    (ii) The quantity traded by the person divided by the quantity 
traded by all the persons who have traded that class II controlled

Sec.82.20  Availability of consumption allowances in addition to 
baseline consumption allowances for class II controlled substances.

    (a) A person may obtain at any time during the control period, in 
accordance with the provisions of this section, consumption allowances 
equivalent to the quantity of class II controlled substances that the 
person exported from the United States and its territories to a foreign 
state in accordance with this section, when that quantity of class II 
controlled substance was produced in the U.S. or imported into the 
United States with expended consumption allowances. Both the export of 
the class II controlled substance and the request for additional 
consumption allowances must occur during a calendar year in which 
consumption allowances were issued for that class II controlled 
substance.
    (1) The exporter must submit to the Administrator a request for 
consumption allowances setting forth the following:
    (i) The identities and addresses of the exporter and the recipient 
of the exports;
    (ii) The exporter's Employer Identification Number;
    (iii) The names and telephone numbers of contact persons for the 
exporter and the recipient;
    (iv) The quantity (in kilograms) and type of class II controlled 
substances reported;
    (v) The source of the class II controlled substances and the date 
purchased;
    (vi) The date on which, and the port from which, the class II 
controlled substances were exported from the U.S. or its territories;
    (vii) The country to which the class II controlled substances were 
exported;
    (viii) A copy of the bill of lading and the invoice indicating the 
net quantity (in kilograms) of class II controlled substances shipped 
and documenting the sale of the class II controlled substances to the 
purchaser;
    (ix) The commodity codes of the class II controlled substances 
reported; and
    (x) A written statement from the producer that the class II 
controlled substances were produced with expended allowances or a 
written statement from the importer that the class II controlled 
substances were imported with expended allowances.
    (2) The Administrator will review the information and documentation 
submitted under paragraph (a)(1) of this section and will issue a 
notice.
    (i) The Administrator will determine the quantity of class II 
controlled substances that the documentation verifies was exported and 
issue consumption allowances equivalent to the quantity of class II 
controlled substances that were exported.
    (A) The grant of the consumption allowances will be effective on the 
date the notice is issued.
    (B) The consumption allowances will be granted to the person the 
exporter indicates, whether it is the producer, the importer, or the 
exporter.
    (ii) The Administrator will issue a notice that the consumption 
allowances are not granted if the Administrator determines that the 
information and documentation do not satisfactorily substantiate the 
exporter's claims.
    (b) International trades of consumption allowances. (1) A person may 
increase its consumption allowances for a specified control period 
through trades with another Party to the Protocol as set forth in this 
paragraph (b). A person may only receive consumption from Poland or 
Norway, or both, and only if the nation agrees to trade to the person 
for the current control period some quantity of consumption that the 
nation is permitted under the Montreal Protocol.
    (2) Trade from a Party--Information requirements. A person must 
submit the following information to the Administrator:
    (i) A signed document from the principal diplomatic representative 
in the Polish or Norwegian embassy in the U.S. stating that the 
appropriate authority within that nation will establish or revise 
consumption limits for the nation to equal the lowest of the following 
three consumption quantities:
    (A) The maximum consumption that the nation is allowed under the 
Protocol minus the quantity (in kilograms) traded;

[[Page 55]]

    (B) The maximum consumption that is allowed under the nation's 
applicable domestic law minus the quantity (in kilograms) traded; or
    (C) The average of the nation's actual consumption level for the 
three years prior to the trade minus the consumption traded.
    (ii) A person requesting a consumption trade from Poland or Norway 
must also submit to the Administrator a true copy of the document that 
sets forth the following:
    (A) The identity and address of the person;
    (B) The identity of the Party;
    (C) The names and telephone numbers of contact persons for the 
person and for the Party;
    (D) The chemical type and quantity (in kilograms) of consumption 
being traded;
    (E) Documentation that the Party possesses the necessary quantity of 
unexpended consumption rights;
    (F) The control period(s) to which the trade applies; and
    (3) Notice of trade. If the request meets the requirement of 
paragraph (b)(2) of this section for trades from Parties, the 
Administrator will issue the person a notice. The notice will grant 
consumption allowances and specify the control period to which the trade 
applies. The Administrator may disapprove the trade request if it does 
not meet the requirements of paragraph (b)(2) of this section.
    (4) Trade from a Party. The Administrator will issue a notice 
revising the allowances held by the recipient of the trade to equal the 
unexpended consumption allowances held by the recipient of the trade 
under this subpart plus the quantity of allowable consumption traded 
from the Party.
    (5) Effective date of revised consumption limits. The change in 
consumption allowances will be effective on the date that the notice is 
issued.

Sec. Sec.82.21-82.22  [Reserved]



Sec.82.23  Transfers of allowances of class II controlled substances.

    (a) Inter-company transfers. Effective January 1, 2003, a person 
(``transferor'') may transfer to any other person (``transferee'') any 
quantity of the transferor's class II consumption allowances, production 
allowances, export production allowances, or Article 5 allowances for 
the same type of allowance as follows:
    (i) The transferor must submit to the Administrator a transfer claim 
setting forth the following:
    (A) The identities and addresses of the transferor and the 
transferee;
    (B) The name and telephone numbers of contact persons for the 
transferor and the transferee;
    (C) The type of allowances being transferred, including the names of 
the class II controlled substances for which allowances are to be 
transferred;
    (D) The quantity (in kilograms) of allowances being transferred;
    (E) The control period(s) for which the allowances are being 
transferred;
    (F) [Reserved]
    (G) For trades of consumption allowances, production allowances, 
export production allowances, or Article 5 allowances, the quantity of 
the 0.1 percent offset applied to the unweighted quantity traded that 
will be deducted from the transferor's allowance balance.
    (ii) The Administrator will determine whether the records maintained 
by EPA indicate that the transferor possesses unexpended allowances 
sufficient to cover the transfer claim on the date the transfer claim is 
processed. The transfer claim is the quantity (in kilograms) to be 
transferred plus 0.1 percent of that quantity. The Administrator will 
take into account any previous transfers, any production, and allowable 
imports and exports of class II controlled substances reported by the 
transferor. Within three working days of receiving a complete transfer 
claim, the Administrator will take action to notify the transferor and 
transferee as follows:
    (A) The Administrator will issue a notice indicating that EPA does 
not object to the transfer if EPA's records

[[Page 56]]

show that the transferor has sufficient unexpended allowances to cover 
the transfer claim. In the case of transfers of production or 
consumption allowances, EPA will reduce the transferor's balance of 
unexpended allowances by the quantity to be transferred plus 0.1 percent 
of that quantity. In the case of transfers of export production or 
Article 5 allowances, EPA will reduce the transferor's balance of 
unexpended allowances, respectively, by the quantity to be transferred 
plus 0.1 percent of that quantity. The transferor and the transferee may 
proceed with the transfer when EPA issues a no objection notice. 
However, if EPA ultimately finds that the transferor did not have 
sufficient unexpended allowances to cover the claim, the transferor and 
transferee, where applicable, will be held liable for any knowing 
violations of the regulations of this subpart that occur as a result of, 
or in conjunction with, the improper transfer.
    (B) The Administrator will issue a notice disallowing the transfer 
if EPA's records show that the transferor has insufficient unexpended 
allowances to cover the transfer claim, or that the transferor has 
failed to respond to one or more Agency requests to supply information 
needed to make a determination. Either party may file a notice of 
appeal, with supporting reasons, with the Administrator within 10 
working days after receipt of notification. The Administrator may affirm 
or vacate the disallowance. If no appeal is taken by the tenth working 
day after notification, the disallowance shall be final on that day.
    (iii) The transferor and transferee may proceed with the transfer if 
the Administrator does not respond to a transfer claim within the three 
working days specified in paragraph (a)(1)(ii) of this section. In the 
case of transfers of production or consumption allowances, EPA will 
reduce the transferor's balance of unexpended allowances by the quantity 
to be transferred plus 0.1 percent of that quantity. In the case of 
transfers of export production allowances or Article 5 allowances, EPA 
will reduce the transferor's balance of unexpended allowances by the 
quantity to be transferred plus 0.1 percent of that quantity. If EPA 
ultimately finds that the transferor did not have sufficient unexpended 
allowances to cover the claim, the transferor and/or the transferee, 
where applicable, will be held liable for any knowing violations of the 
regulations of this subpart that occur as a result of, or in conjunction 
with, the improper transfer.
    (b) Inter-pollutant transfers. (1) Effective January 1, 2003, a 
person (transferor) may convert consumption allowances, production 
allowances or Article 5 allowances for one class II controlled substance 
to the same type of allowance for another class II controlled substance 
listed in appendix B of this subpart, following the procedures described 
in paragraph (b)(3) of this section.
    (i) A person (transferor) may only convert allowances for one class 
II controlled substance for which EPA has issued allowances under Sec.
82.16 to another class II controlled substance for which EPA has issued 
allowances under Sec.82.16.
    (ii) [Reserved]
    (2) Inter-pollutant transfers will be permitted at any time during 
the control period and during the 30 days after the end of a control 
period.
    (3) The transferor must submit to the Administrator a transfer claim 
that includes the following:
    (i) The identity and address of the transferor;
    (ii) The name and telephone number of a contact person for the 
transferor;
    (iii) The type of allowances being converted, including the names of 
the class II controlled substances for which allowances are to be 
converted;
    (iv) The quantity (in kilograms) and type of allowances to be 
converted;
    (v) The quantity (in kilograms) of allowances to be subtracted from 
the transferor's unexpended allowances for the first class II controlled 
substance, to be equal to 100.1 percent of the quantity of allowances 
converted;
    (vi) The quantity (in kilograms) of allowances to be added to the 
transferee's unexpended allowances for the second class II controlled 
substance, to be equal to the quantity (in kilograms)

[[Page 57]]

of allowances for the first class II controlled substance being 
converted multiplied by the quotient of the ozone depletion potential of 
the first class II controlled substance divided by the ozone depletion 
potential of the second class II controlled substance, as listed in 
Appendix B to this subpart;
    (vii) The control period(s) for which the allowances are being 
converted; and
    (viii) The quantity (in kilograms) of unexpended allowances of the 
type and for the control period being converted that the transferor 
holds under authority of this subpart as of the date the claim is 
submitted to EPA.
    (4) The Administrator will determine whether the records maintained 
by EPA indicate that the convertor possesses unexpended allowances 
sufficient to cover the transfer claim on the date the transfer claim is 
processed (i.e., the quantity (in kilograms) to be converted plus 0.1 
percent of that quantity (in kilograms)). EPA will take into account any 
previous transfers, and any production, imports (not including 
transshipments or used class II controlled substances), or exports (not 
including transhipments or used class II controlled substances) of class 
II controlled substances reported by the convertor. Within three working 
days of receiving a complete transfer claim, the Administrator will take 
action to notify the convertor as follows:
    (i) The Administrator will issue a notice indicating that EPA does 
not object to the transfer if EPA's records show that the convertor has 
sufficient unexpended allowances to cover the transfer claim. EPA will 
reduce the transferor's balance of unexpended allowances by the quantity 
to be converted plus 0.1 percent of that quantity (in kilograms). When 
EPA issues a no objection notice, the transferor may proceed with the 
transfer. However, if EPA ultimately finds that the transferor did not 
have sufficient unexpended allowances to cover the claim, the transferor 
will be held liable for any violations of the regulations of this 
subpart that occur as a result of, or in conjunction with, the improper 
transfer.
    (ii) The Administrator will issue a notice disallowing the transfer 
if EPA's records show that the transferor has insufficient unexpended 
allowances to cover the transfer claim, or that the transferor has 
failed to respond to one or more Agency requests to supply information 
needed to make a determination. The transferor may file a notice of 
appeal, with supporting reasons, with the Administrator within 10 
working days after receipt of notification. The Administrator may affirm 
or vacate the disallowance. If no appeal is taken by the tenth working 
day after notification, the disallowance shall be final on that day.
    (iii) The transferor may proceed with the transfer if the 
Administrator does not respond to a transfer claim within the three 
working days specified in paragraph (b)(4) of this section. EPA will 
reduce the transferor's balance of unexpended allowances by the quantity 
(in kilograms) to be converted plus 0.1 percent of that quantity (in 
kilograms). The transferor will be held liable for any violations of the 
regulations of this subpart that occur as a result of, or in conjunction 
with, the improper transfer if EPA ultimately finds that the transferor 
did not have sufficient unexpended allowances or credits to cover the 
claim.
    (c) Inter-company transfers and Inter-pollutant transfers. If a 
person requests an inter-company transfer and an inter-pollutant 
transfer simultaneously, the quantity (in kilograms) subtracted from the 
transferor's unexpended production or consumption allowances for the 
first class II controlled substance will be equal to 100.1 percent of 
the quantity (in kilograms) of allowances that are being converted and 
transferred.
    (d) Permanent transfers. The procedures in paragraph (a) of this 
section apply to permanent inter-company transfers of baseline 
production allowances or baseline consumption allowances. A person 
receiving a permanent transfer of baseline production allowances or 
baseline consumption allowances (the transferee) for a specific class II 
controlled substance will be the person who has their baseline 
allowances adjusted in accordance with phaseout schedules in this 
subpart. No person may conduct permanent inter-

[[Page 58]]

pollutant transfers of baseline production allowances or baseline 
consumption allowances.

substances imported for destruction, and the contact person's name, 
email address, and phone number;
    (iv) The U.S. port of entry for the import, the expected date of 
shipment and the vessel transporting the material. If at the time of 
submitting the certification of intent to import for destruction the 
importer does not know the U.S. port of entry, the expected date of 
shipment and the vessel transporting the material, and the importer 
receives a non-objection notice for the individual shipment in the 
petition, the importer is required to notify the Administrator of this 
information prior

  been determined from calculations based on laboratory measurements.
  Those listed as a range are based on estimates and are less certain.
  The range pertains to an isomeric group. The upper value is the

           Sec. Appendix C to Subpart A of Part 82 [Reserved]



  Sec. Appendix D to Subpart A of Part 82--Harmonized Tariff Schedule 
   Description of Products That May Contain Controlled Substances in 
                  Appendix A, Class I, Groups I and II

    This appendix is based on information provided by the Ozone 
Secretariat of the United Nations Ozone Environment Programme.** The 
Appendix lists available U.S. harmonized tariff schedule codes 
identifying headings and subheadings for Annex D products that may 
contain controlled substances.
---------------------------------------------------------------------------

    ** ``A Note Regarding the Harmonized System Code Numbers for the 
Products Listed in Annex D.'' Adopted by Decision IV/15 paragraph 3, of 
the Fourth Meeting of the Parties in Copenhagen, 23-25 November, 1992.
---------------------------------------------------------------------------

    The Harmonized Tariff Schedule of the United States uses an 
enumeration system to identify products imported and exported to and 
from the U.S. This system relies on a four digit heading, a four digit 
subheading and additional two digit statistical suffix to characterize 
products. The United States uses the suffix for its own statistical 
records and analyses. This Appendix lists only headings and subheadings.
    While some can be readily associated with harmonized system codes, 
many products cannot be tied to HS classifications unless their exact 
composition and the presentation are known. It should be noted that the 
specified HS classifications represent the most likely headings and 
subheadings which may contain substances controlled by the Montreal 
Protocol. The codes given should only be used as a starting point; 
further verfication is needed to ascertain whether or not the products 
actually contain controlled substances.

    Category 1. Automobile and Truck Air Conditioning Units (whether 
                    incorporated in vehicles or not)

    There are no separate code numbers for air conditioning units 
specially used in automobiles and trucks. Although a code has been 
proposed for car air conditioners, it is not yet officially listed in 
the Harmonized

[[Page 68]]

Tariff Schedule (see category 2). The following codes apply to the 
vehicles potentially containing air conditioning units.

                        Category 6. Pre-Polymers

    According to the Explanatory Notes to the Harmonized Commodity 
Description and Coding System, ``prepolymers are products which are 
characterized by some repetition of monomer units although they may 
contain unreacted monomers. Prepolymers are not normally used as such 
but are intended to be transformed into higher molecular weight polymers 
by further polymerization. Therefore the term does not cover finished 
products, such as di-isobutylenes or mixed polyethylene glycols with 
very low molecular weight. Examples are epoxides based with 
epichlorohydrin, and polymeric isocyanates.''

   Sec. Appendix G to Subpart A of Part 82--UNEP Recommendations for 
Conditions Applied to Exemption for Essential Laboratory and Analytical 
                                  Uses

    1. Essential laboratory and analytical uses are identified at this 
time to include equipment calibration; use as extraction solvents, 
diluents, or carriers for chemical analysis;
      

[[Page 75]]

biochemical research; inert solvents for chemical reactions, as a 
carrier or laboratory chemical and other critical analytical and 
laboratory purposes. Pursuant to Decision XI/15 of the Parties to the 
Montreal Protocol, effective January 1, 2002 the following uses of class 
I controlled substances are not considered essential under the global 
laboratory exemption:
    a. Testing of oil and grease and total petroleum hydrocarbons in 
water;
    b. Testing of tar in road-paving materials; and
    c. Forensic finger printing.
    Production for essential laboratory and analytical purposes is 
authorized provided that these laboratory and analytical chemicals shall 
contain only controlled substances manufactured to the following 
purities:

CTC (reagent grade)--99.5
1,1,1,-trichloroethane--99.5
CFC-11--99.5
CFC-13--99.5
CFC-12--99.5
CFC-113--99.5
CFC-114--99.5
Other w/ Boiling P20 degrees C--99.5
Other w/ Boiling P<20 degrees C--99.0
    d. Testing of organic matter in coal.
    2. These pure, controlled substances can be subsequently mixed by 
manufacturers, agents or distributors with other chemicals controlled or 
not controlled by the Montreal Protocol as is customary for laboratory 
and analytical uses.
    3. These high purity substances and mixtures containing controlled 
substances shall be supplied only in re-closable containers or high 
pressure cylinders smaller than three litres or in 10 millilitre or 
smaller glass ampoules, marked clearly as substances that deplete the 
ozone layer, restricted to laboratory use and analytical purposes and 
specifying that used or surplus substances should be collected and 
recycled, if practical. The material should be destroyed if recycling is 
not practical.
    4. Parties shall annually report for each controlled substance 
produced: the purity; the quantity; the application, specific test 
standard, or procedure requiring its uses; and the status of efforts to 
eliminate its use in each application. Parties shall also submit copies 
of published instructions, standards, specifications, and regulations 
requiring the use of the controlled substance.
    5. Pursuant to Decision XVIII/15 of the Parties to the Montreal 
Protocol, methyl bromide is exempted for the following approved 
essential laboratory and analytical purposes listed in following items 
(a) through (d). Use of methyl bromide for field trials is not an 
approved use under the global laboratory and analytical use exemption. 
The provisions of Appendix G, paragraphs (1), (2), (3), and (4), 
regarding purity, mixing, container, and reporting requirements for 
other exempt ODSs, also apply to the use of methyl bromide under this 
exemption.
    a. Methyl bromide is exempted as an approved essential laboratory 
and analytical use as a reference or standard to calibrate equipment 
which uses methyl bromide, to monitor methyl bromide emission levels, or 
to determine methyl bromide residue levels in goods, plants and 
commodities;
    b. Methyl bromide is exempted as an approved essential laboratory 
and analytical when used in laboratory toxicological studies;
    c. Methyl bromide is exempted as an approved essential laboratory 
and analytical use to compare the efficacy of methyl bromide and its 
alternatives inside a laboratory; and
    d. Methyl bromide is exempted as an approved essential laboratory 
and analytical use as a laboratory agent which is destroyed in a 
chemical reaction in the manner of feedstock.

Sec.82.32  Definitions.

    (a) Approved independent standards testing organization means any 
organization which has applied for and received approval from the 
Administrator pursuant to Sec.82.38.
    (b) Approved refrigerant recycling equipment means equipment 
certified by the Administrator or an organization approved under Sec.
82.38 as meeting either one of the standards in Sec.82.36. Such 
equipment extracts and recycles refrigerant or extracts refrigerant for 
recycling on-site or reclamation off-site.
    (c) Motor vehicle as used in this subpart means any vehicle which is 
self-propelled and designed for transporting persons or property on a 
street or highway, including but not limited to passenger cars, light 
duty vehicles, and heavy duty vehicles. This definition does not include 
a vehicle where final assembly of the vehicle has not been completed by 
the original equipment manufacturer.
    (d) Motor vehicle air conditioners means mechanical vapor 
compression refrigeration equipment used to cool the driver's or 
passenger's compartment of any motor vehicle. This definition is not 
intended to encompass the hermetically sealed refrigeration systems used 
on motor vehicles for refrigerated cargo and the air conditioning 
systems on passenger buses using HCFC-22 refrigerant.
    (e) Properly using. (1) Properly using means using equipment in 
conformity with the regulations set forth in this subpart, including but 
not limited to the prohibitions and required practices set forth in 
Sec.82.34, and the recommended service procedures and practices for 
the containment of refrigerant set forth in Sec.82.36(a) and 
appendices A, B, C, D, E, and F to this subpart, as applicable. In 
addition, this term includes operating the equipment in accordance with 
the manufacturer's guide to operation and maintenance and using the 
equipment only for the controlled substance for which the machine is 
designed. For equipment that extracts and recycles refrigerant, properly 
using also means to recycle refrigerant before it is returned to a motor 
vehicle air conditioner or MVAC-like appliance, including to the motor 
vehicle air conditioner or MVAC-like appliance from which the 
refrigerant was extracted. For equipment that only recovers refrigerant, 
properly using includes the requirement to recycle the refrigerant on-
site or send the refrigerant off-site for reclamation.
    (2) Refrigerant from reclamation facilities that is used for the 
purpose of recharging motor vehicle air conditioners must be at or above 
the standard of purity developed by the Air-conditioning and 
Refrigeration Institute (ARI 700-93) (which is codified at 40 CFR part 
82, subpart F, appendix A, and is available at 4301 North Fairfax Drive, 
Suite 425, Arlington, Virginia 22203). Refrigerant may be recycled off-
site only if the refrigerant is extracted using recover only equipment, 
and is subsequently recycled off-site by equipment owned by the person 
that owns both the recover only equipment and owns or operates the 
establishment at which the refrigerant was extracted. In any event, 
approved equipment must be used to extract refrigerant prior to 
performing any service during which discharge of refrigerant from the 
motor vehicle air conditioner can reasonably be expected. Intentionally 
venting or disposing of refrigerant to the atmosphere is an improper use 
of equipment.
    (3) Notwithstanding any other terms of this paragraph (e), approved 
refrigerant recycling equipment may be transported off-site and used to 
perform service involving refrigerant at other locations where such 
servicing occurs. Any such servicing involving refrigerant must meet all 
of the requirements of this subpart B that would apply if the servicing 
occurred on-site.
    (4) Facilities that charge MVACs or MVAC-like appliances with 
refrigerant but do not perform any other service involving refrigerant 
(i.e., perform ``top-offs'' only) are considered to be engaged in 
``service involving refrigerant'' and are therefore subject to any and 
all requirements of this subsection that apply to facilities that 
perform a wider range of refrigerant servicing. For facilities that 
charge MVACs, this

[[Page 79]]

includes the requirement to purchase approved refrigerant recycling 
equipment. For facilities that only charge MVAC-like appliances, this 
does not include the requirement to purchase approved refrigerant 
recycling equipment, but does include the requirement to be properly 
trained and certified by a technician certification program approved by 
the Administrator pursuant to either Sec.82.40 or Sec.82.161(a)(5).
    (5) All persons opening (as that term is defined in Sec.82.152) 
MVAC-like appliances must have at least one piece of approved recovery 
or recycling equipment available at their place of business.
    (f) Refrigerant means any class I or class II substance used in a 
motor vehicle air conditioner. Class I and class II substances are 
listed in part 82, subpart A, appendix A. Effective November 15, 1995, 
refrigerant shall also include any substitute substance.
    (g) Service for consideration means being paid to perform service, 
whether it is in cash, credit, goods, or services. This includes all 
service except that done for free.
    (h) Service involving refrigerant means any service during which 
discharge or release of refrigerant from the MVAC or MVAC-like appliance 
to the atmosphere can reasonably be expected to occur. Service involving 
refrigerant includes any service in which an MVAC or MVAC-like appliance 
is charged with refrigerant but no other service involving refrigerant 
is performed (i.e., a ``top-off'').
    (i) Motor vehicle disposal facility means any commercial facility 
that engages in the disposal (which includes dismantling, crushing or 
recycling) of MVACs or MVAC-like appliances, including but not limited 
to automotive recycling facilities, scrap yards, landfills and salvage 
yards engaged in such operations. Motor vehicle repair and/or servicing 
facilities, including collision repair facilities, are not considered 
motor vehicle disposal facilities.

[57 FR 31261, July 14, 1992, as amended at 60 FR 21687, May 2, 1995; 62 
FR 68046, Dec. 30, 1997; 86 FR 15595, Mar. 24, 2021]



Sec.82.34  Prohibitions and required practices.

    (a) No person repairing or servicing MVACs for consideration, and no 
person repairing or servicing MVAC-like appliances, may perform any 
service involving the refrigerant for such MVAC or MVAC-like appliance:
    (1) Without properly using equipment approved pursuant to Sec.
82.36;
    (2) Unless any such person repairing or servicing an MVAC has been 
properly trained and certified by a technician certification program 
approved by the Administrator pursuant to Sec.82.40; and
    (3) Unless any such person repairing or servicing an MVAC-like 
appliance has been properly trained and certified by a technician 
certification program approved by the Administrator pursuant to either 
Sec.82.40 or Sec.82.161(a)(5).
    (b) Effective November 15, 1992, no person may sell or distribute, 
or offer for sale or distribution, any class I or class II substance 
that is suitable for use as a refrigerant in motor vehicle air-
conditioner and that is in a container which contains less than 20 
pounds of such refrigerant to any person unless that person is properly 
trained and certified under Sec.82.40 or intended the containers for 
resale only, and so certifies to the seller under Sec.82.42(b)(3).
    (c) No technician training programs may issue certificates unless 
the program complies with all of the standards in Sec.82.40(a).
    (d) Motor vehicle disposal facilities. (1) Any refrigerant that is 
extracted from an MVAC or an MVAC-like appliance (as that term is 
defined in Sec.82.152) bound for disposal and located at a motor 
vehicle disposal facility may not be subsequently used to charge or 
recharge an MVAC or MVAC-like appliance, unless, prior to such charging 
or recharging, the refrigerant is either:
    (i) Recovered, and reclaimed in accordance with the regulations 
promulgated under Sec.82.32(e)(2) of this subpart B; or
    (ii) (A) Recovered using approved refrigerant recycling equipment 
dedicated for use with MVACs and MVAC-like appliances, either by a 
technician certified under paragraph (a)(2) of this section, or by an 
employee, owner, or

[[Page 80]]

operator of, or contractor to, the disposal facility; and
    (B) Subsequently recycled by the facility that charges or recharges 
the refrigerant into an MVAC or MVAC-like appliance, properly using 
approved refrigerant recycling equipment in accordance with any 
applicable recommended service procedures set forth in the appendices to 
this subpart B.
    (2) Any refrigerant the sale of which is restricted under subpart F 
that is extracted from an MVAC or an MVAC-like appliance bound for 
disposal and located at a motor vehicle disposal facility but not 
subsequently reclaimed in accordance with the regulations promulgated 
under subpart F, may be sold prior to its subsequent re-use only to a 
technician certified under paragraph (a)(2) of this section. Any 
technician certified under paragraph (a)(2) of this section who obtains 
such a refrigerant may subsequently re-use such refrigerant only in an 
MVAC or MVAC-like appliance, and only if it has been reclaimed or 
properly recycled.
    (e) Refrigerant handling equipment manufactured or imported for use 
during the maintenance, service or repair of MVACs for consideration 
cannot be introduced into interstate commerce unless meeting the 
requirements of Sec.82.36.

[57 FR 31261, July 14, 1992, as amended at 62 FR 68047, Dec. 30, 1997; 
72 FR 63494, Nov. 9, 2007]

      Standard of Purity for Use in Mobile Air-Conditioning Systems

                                Foreword

    Due to the CFC's damaging effect on the ozone layer, recycle of CFC-
12 (R-12) used in mobile air-conditioning systems is required to reduce 
system venting during normal service operations. Establishing recycle 
specifications for R-12 will assure that system operation with recycled 
R-12 will provide the same level of performance as new refrigerant.
    Extensive field testing with the EPA and the auto industry indicate 
that reuse of R-12 removed from mobile air-conditioning systems can be 
considered, if the refrigerant is cleaned to a specific standard. The 
purpose of this standard is to establish the specific minimum levels of 
R-12 purity required for recycled R-12 removed from mobile automotive 
air-conditioning systems.

local requirements on equipment related to the handling of R-12 
material. Safety precautions or notices related to the safe operation of 
the equipment shall be prominently displayed on the equipment and should 
also state ``Caution--Should Be Operated By Qualified Personnel''.

                        6. Operating Instructions

    6.1 The equipment manufacturer must provide operating instructions, 
necessary maintenance procedures, and source information for replacement 
parts and repair.
    6.2 The equipment must prominently display the manufacturer's name, 
address and any items that require maintenance or replacement that 
affect the proper operation of the equipment. Operation manuals must 
cover information for complete maintenance of the equipment to assure 
proper operation.

                        7. Functional Description

    7.1 The equipment must be capable of ensuring recovery of the R-12 
from the system being service, by reducing the system pressure below 
atmospheric to a minimum of 102 mm of mercury.
    7.2 To prevent overcharge, the equipment must be equipped to protect 
the tank used to store the recycled refrigerant with a shutoff device 
and a mechanical pressure relief valve.
    7.3 Portable refillable tanks or containers used in conjunction with 
this equipment must meet applicable Department of Transportation (DOT) 
or Underwriters Laboratories (UL) Standards and be adaptable to existing 
refrigerant service and charging equipment.
    7.4 During operation, the equipment shall provide overfill 
protection to assure the storage container, internal or external, liquid 
fill does not exceed 80% of the tank's rated volume at 21.1 [deg]C (70 
[deg]F) per DOT standards, CFR title 49, Sec.173.304 and American 
Society of Mechanical Engineers.
    7.4.1 Additional Storage Tank Requirements.
    7.4.1.1 The cylinder valve shall comply with the standard for 
cylinder valves, UL 1769.
    7.4.1.2 The pressure relief device shall comply with the Pressure 
Relief Device Standard Part 1--Cylinders for Compressed Gases, CGA 
Pamphlet S-1.1.
    7.4.1.3 The tank assembly shall be marked to indicate the first 
retest date, which shall be 5 years after date of manufacture. The 
marking shall indicate that retest must be performed every subsequent 5 
years. The marking shall be in letters at least \1/4\ in high.
    7.5 All flexible hoses must meet SAE J2196 hose specification 
effective January 1, 1992.
    7.6 Service hoses must have shutoff devices located within 30 cm (12 
in) of the connection point to the system being serviced to minimize 
introduction of noncondensable gases into the recovery equipment and the 
release of the refrigerant when being disconnected.
    7.7 The equipment must be able to separate the lubricant from the 
recovered refrigerant and accurately indicate the amount removed during 
the process, in 30 ml units. Refrigerant dissolves in lubricant sample. 
This creates the illusion that more lubricant has been recovered than 
actually has been. The equipment lubricant measuring system must take in 
account such dissolved refrigerant to prevent overcharging the vehicle 
system with lubricant. Note: Use only new lubricant to replace the 
amount removed during the recycle process. Used lubricant should be 
discarded per applicable federal, state, and local requirements.
    7.8 The equipment must be capable of continuous operation in ambient 
of 10 to 49 [deg]C (50 to 120 [deg]F).
    7.9 The equipment should be compatible with leak detection material 
that may be present in the mobile AC system.

                               8. Testing

    This test procedure and the requirement are used for evaluation of 
the equipment for its ability to clean the contaminated R-12 
refrigerant.
    8.1 The equipment shall clean the contaminated R-12 refrigerant to 
the minimum purity level as defined in SAE J1991, when tested in 
accordance with the following conditions:
    8.2 For test validation, the equipment is to be operated according 
to the manufacturer's instructions.
    8.3 The equipment must be preconditioned with 13.6 kg (30 lb) of the 
standard contaminated R-12 at an ambient of 21 [deg]C (70 [deg]F) before 
starting the test cycle. Sample amounts are not to exceed 1.13 kg (2.5 
lb) with sample amounts to be repeated every 5 min. The sample method 
fixture, defined in Fig. 1, shall be operated at 24 [deg]C (75 [deg]F).
    8.4 Contaminated R-12 Samples.
    8.4.1 Standard contaminated R-12 refrigerant shall consist of liquid 
R-12 with 100

[[Page 88]]

ppm (by weight) moisture at 21 [deg]C (70 [deg]F) and 45,000 ppm (by 
weight) mineral oil 525 suspension nominal and 770 ppm by weight of 
noncondensable gases (air).
    8.4.2 High moisture contaminated sample shall consist of R-12 vapor 
with 1,000 ppm (by weight) moisture.
    8.4.3 High oil contaminated sample shall consist of R-12 with 
200,000 ppm (by weight) mineral oil 525 suspension viscosity nominal.
    8.5 Test Cycle.
    8.5.1 After preconditioning as stated in 8.3, the test cycle is 
started, processing the following contaminated samples through the 
equipment:
    8.5.1.1 3013.6 kg (30 lb) of standard contaminated R-12.
    8.5.1.2 1 kg (2.2 lb) of high oil contaminated R-12.
    8.5.1.3 4.5 kg (10 lb) of standard contaminated R-12.
    8.5.1.4 1 kg (2.2 lb) of high moisture contaminated R-12.
    8.6 Equipment Operating Ambient.
    8.6.1 The R-12 is to be cleaned to the minimum purity level, as 
defined in SAE J1991, with the equipment operating in a stable ambient 
of 10, 21, and 49 [deg]C (50, 70, and 120 [deg]F) and processing the 
samples as defined in 8.5.
    8.7 Sample Analysis.
    8.7.1 The processed contaminated sample shall be analyzed according 
to the following procedure.
    8.8 Quantitative Determination of Moisture.
    8.8.1 The recycled liquid phase sample of CFC-12 shall be analyzed 
for moisture content via Karl Fischer coulometer titration or an 
equivalent method. The Karl Fischer apparatus is an instrument for 
precise determination of small amounts of water dissolved in liquid and/
or gas samples.
    8.8.2 In conducting the test, a weighed sample of 30 to 130 grams is 
vaporized directly into the Karl Fischer analyte. A coulometer titration 
is conducted and the results are calculated and displayed as parts per 
million moisture (weight).
    8.9 Determination of Percent Lubricant.
    8.9.1 The amount of oil in the recycled sample of CFC-12 is to be 
determined by gravimetric analysis.
    8.9.2 Following venting of noncondensable, in accordance with the 
manufacturer's operating instructions, the refrigerant container shall 
be shaken for 5 minutes prior to extracting samples for test.
    8.9.3 A weighted sample of 175 to 225 grams of liquid CFC-12 is 
allowed to evaporate at room temperature. The percent oil is to be 
calculated from the weight of the original sample and the residue 
remaining after the evaporation.
    8.10 Noncondensable Gas.
    8.10.1 The amount of noncondensable gas is to be determined by gas 
chromatography. A sample of vaporized refrigerant liquid shall be 
separated and analyzed by gas chromatography. A Porapak Q column at 130 
[deg]C and a hot wire detector may be used for analysis.
    8.10.2 This test shall be conducted on recycled refrigerant (taken 
from the liquid phase) within 30 minutes after the proper venting of 
noncondensable.
    8.10.3 Samples shall be shaken for 8 hours prior to retesting while 
at a temperature of 24 2.8 [deg]C (75 5 [deg]F). Known volumes of refrigerant vapor are to be 
injected for separation and analysis by means of gas chromatography. A 
Porapak Q column at 130 [deg]C (266 [deg]F) and a hot wire detector are 
to be used for the analysis.
    8.10.4 This test shall be conducted at 21 and 49 [deg]C and may be 
performed in conjunction with the testing defined in Section 8.6. The 
equipment shall process at least 13.6 kg of standard contaminated 
refrigerant for this test.
    8.11 Sample Requirements.
    8.11.1 The sample shall be tested as defined in 8.7, 8.8, 8.9, and

        Recommended Service Procedure for the Containment of R-12

                                1. Scope

    During service of mobile air-conditioning systems, containment of 
the refrigerant is important. This procedure provides service guidelines 
for technicians when repairing vehicles and operating equipment defined 
in SAE J1990.

[[Page 90]]

                              2. References

SAE J1990, Extraction and Recycle Equipment for Mobile Automotive Air-
Conditioning Systems

                    3. Refrigerant Recovery Procedure

    3. 1 Connect the recovery unit service hoses, which shall have 
shutoff valves within 12 in (30 cm) of the service ends, to the vehicle 
air-conditioning system service ports.
    3.2 Operate the recovery equipment as covered by the equipment 
manufacturers recommended procedure.
    3.2.1 Start the recovery process and remove the refrigerant from the 
vehicle AC system. Operate the recovery unit until the vehicle system 
has been reduced from a pressure to a vacuum. With the recovery unit 
shut off for at least 5 min, determine that there is no refrigerant 
remaining in the vehicle AC system. If the vehicle system has pressure, 
additional recovery operation is required to remove the remaining 
refrigerant. Repeat the operation until the vehicle AC system vacuum 
level remains stable for 2 min.
    3.3 Close the valves in the service lines and then remove the 
service lines from the vehicle system. Proceed with the repair/service. 
If the recovery equipment has automatic closing valves, be sure they are 
properly operating.

                    4. Service With Manifold Gage Set

    4.1 Service hoses must have shutoff valves in the high, low, and 
center service hoses within 12 in (30 cm) of the service ends. Valves 
must be closed prior to hose removal from the air-conditioning system. 
This will reduce the volume of refrigerant contained in the service hose 
that would otherwise be vented to atmosphere.
    4.2 During all service operations, the valves should be closed until 
connected to the vehicle air-conditioning system or the charging source 
to avoid introduction of air and to contain the refrigerant rather than 
vent open to atmosphere.
    4.3 When the manifold gage set is disconnected from the air-
conditioning system or when the center hose is moved to another device 
which cannot accept refrigerant pressure, the gage set hoses should 
first be attached to the reclaim equipment to recover the refrigerant 
from the hoses.

5. Recycled Refrigerant Checking Procedure for Stored Portable Auxiliary 
                                Container

    5.1 To determine if the recycled refrigerant container has excess 
noncondensable gases (air), the container must be stored at a 
temperature of 65 [deg]F (18.3 [deg]C) or above for a period of time, 12 
h, protected from direct sun.
    5.2 Install a calibrated pressure gage, with 1 psig divisions (0.07 
kg), to the container and determine the container pressure.
    5.3 With a calibrated thermometer, measure the air temperature 
within 4 in (10 cm) of the container surface.
    5.4 Compare the observed container pressure and air temperature to 
determine if the container exceeds the pressure limits found on Table 1, 
e.g., air temperature 70 [deg]F (21 [deg]C) pressure must not exceed 80 
psig (5.62 kg/cm \2\).

    5.5 If the container pressure is less than the Table 1 values and 
has been recycled, limits of noncondensable gases (air) have not been 
exceeded and the refrigerant may be used.
    5.6 If the pressure is greater than the range and the container 
contains recycled material, slowly vent from the top of the container a 
small amount of vapor into the recycle equipment until the pressure is 
less than the pressure shown on Table 1.
    5.7 If the container still exceeds the pressure shown on Table 1, 
the entire contents of the container shall be recycled.

            6. Containers for Storage of Recycled Refrigerant

    6.1 Recycled refrigerant should not be salvaged or stored in 
disposable refrigerant containers. This is the type of container in 
which virgin refrigerant is sold. Use only DOT CFR title 49 or UL 
approved storage containers for recycled refrigerant.
    6.2 Any container of recycled refrigerant that has been stored or 
transferred must be checked prior to use as defined in section 5.

                   7. Transfer of Recycled Refrigerant

    7.1 When external portable containers are used for transfer, the 
container must be evacuated at least 27 in of vacuum (75 mm Hg absolute 
pressure) prior to transfer of the recycled refrigerant. External 
portable containers must meet DOT and UL standards.
    7.2 To prevent on-site overfilling when transferring to external 
containers, the safe filling level must be controlled by weight and must 
not exceed 60% of container gross weight rating.

               8. Disposal of Empty/Near Empty Containers

    8.1 Since all the refrigerant may not be removed from disposable 
refrigerant containers during normal system charging procedures, empty/
near empty container contents should be reclaimed prior to disposal of 
the container.
    8.2 Attach the container to the recovery unit and remove the 
remaining refrigerant. When the container has been reduced from a 
pressure to a vacuum, the container valve can be closed. The container 
should be marked empty and is ready for disposal.

 Sec. Appendix B to Subpart B of Part 82--Standard for Recover 
 Equipment

    SAE J1989, Recommended Service Procedure for the Containment of R-
12, as set forth under Appendix A, also applies to this Appendix B.
    SAE J2209, issued June, 1992.

SAE Recommended Practice: CFC-12 (R-12) Extraction Equipment for Mobile 
                   Automotive Air-Conditioning Systems

                                Foreword

    CFCs deplete the stratospheric ozone layer that protects the earth 
against harmful ultraviolet radiation. To reduce the emissions

[[Page 92]]

of CFCs, the 1990 Clean Air Act requires recycle of CFC-12 (R-12) used 
in mobile air-conditioning systems to eliminate system venting during 
service operations. SAE J1990 establishes equipment specifications for 
on-site recovery and reuse of CFCs in mobile air-conditioning systems. 
Establishing extraction equipment specifications for CFC-12 will provide 
service facilities with equipment to assure that venting of refrigerant 
will not occur.

                                1. Scope

    The purpose of this document is to provide equipment specifications 
for CFC-12 (R-12) recovery for recycling on-site or for transport off-
site to a refrigerant reclamation facility that will process it to ARI 
(Air-Conditioning and Refrigeration Institute) standard 700-93 as a 
minimum. It is not acceptable that the refrigerant removed from a mobile 
air-conditioning system, with this equipment, be directly returned to a 
mobile air-conditioning system.
    This information applies to equipment used to service automobiles, 
light trucks, and other vehicles with similar CFC-12 systems.

                        7. Functional Description

    The ability of the equipment to meet the refrigerant recovery and 
recharge specifications of this section shall be determined by the test 
procedures of Section 10.
    7.1 The equipment must be capable of continuous operation in ambient 
temperatures of 10 [deg]C (50 [deg]F) to 49 [deg]C (120 [deg]F). 
Continuous is defined as completing recovery/recycle and recharge (if 
applicable) operations with no more than a brief reset period between 
vehicles, and shall not include time delays for allowing a system to 
outgas (which shall be part of the recovery period provided by this 
standard). Continuous may include time out for an air purge if 
necessary, although it is understood that extended equipment-off time is 
preferred to allow NCG and refrigerant separation in the supply tank for 
optimum results.
    7.1.1 The equipment shall be capable of removing a minimum of 95.0% 
of the refrigerant from the test system in 30 minutes or less, without 
external heating, or use of any device (such as shields, reflectors, 
special lights, etc.) which could heat components of the system. The 
recovery procedures shall be based on 21 to 24 [deg]C (70 to 75 [deg]F) 
ambient temperature. The test system for qualifying shall be a 1.4 kg 
(3.0 lbs) capacity orifice tube/accumulator system in a 2005 Chevrolet 
Suburban with front and rear A/C, or the test option described in 10.5, 
and shall be determined by accurately weighing the recovery machine with 
the resolution and accuracy of within 3 g (.006 lb) in the range of the 
machine's weight. The laboratory shall maintain records of the vehicle, 
including its VIN (vehicle identification number).
    7.1.2 However, the preceding shall not preclude a brief period of 
engine operation at fast idle (up to 15 minutes, up to 2000 rpm) to 
circulate refrigerant and oil, and provide some engine and warm-up of A/
C refrigeration components. The laboratory shall monitor coolant 
temperature per the vehicle engine coolant temperature sensor, and 
coolant temperature shall not be allowed to exceed 105 [deg]C (221 
[deg]F). The time required shall not be included in the total time of 30 
minutes set forth in 7.1.1.
    7.1.3 The refrigerant that is recovered, following oil separation, 
shall be measured and the quantity displayed, accurate to

[[Page 96]]

within 30 g (1.0 oz). The equipment must include a 
provision for checking the accuracy, per the requirements of 9.1.
    7.2 During recovery operation, the equipment shall provide overfill 
protection to assure that the liquid fill of the storage container 
(which may be integral or external) does not exceed 80% of the tank's 
rated volume at 21 [deg]C per Department of Transportation (DOT) 
Standard, CFR Title 49, Section 173.304 and the American Society of 
Mechanical Engineers.
    7.3 Portable refillable tanks or containers used in conjunction with 
this equipment must be labeled ``HFC-134a (R-134a),'' meet applicable 
Department of Transportation (DOT) or Underwriters Laboratories (UL) 
Standards, and shall incorporate fittings per SAE J2197.
    7.3.1 The cylinder valve shall comply with the standard for cylinder 
valves, UL 1769.
    7.3.2 The pressure relief device shall comply with the Pressure 
Relief Device Standard Part 1--Cylinders for Compressed Gases, CGA 
Pamphlet S-1.1.
    7.3.3 The tank assembly shall be marked to indicate the first retest 
date, which shall be 5 years after the date of manufacture. The marking 
shall indicate that retest must be performed every subsequent 5 years. 
SAE J2296 provides an inspection procedure. The marking shall be in 
letters at least 6 mm (\1/4\ in) high.
    7.3.4 ASME tanks as defined in UL-1963 may be used and are exempt 
from the retest requirements.
    7.3.5 If the machine is designed for recharging, and the marketer 
permits use of a non-refillable refrigerant tank, the machine shall 
include a way to ensure refrigerant remaining in the tank (called the 
``heel'') to no more than 2% of tank rated capacity when the tank is 
indicated to be empty. This may be done by the machine marketer as 
follows:
     Specify a non-venting procedure, to minimize the 
amount of unused refrigerant remaining in the tank. The machine shall 
include any devices required for the procedure, other than ordinary 
service shop tools and supplies, and include in the operator's manual, 
any instructions.
     Provide an automatic or (with instructions in the 
operator's manual) semi-automatic non-venting procedure with the 
machine.
    The laboratory shall test for the 2% capability. For testing 
purposes it may use a refillable tank, minimum 15 lb capacity (6.8 kg) 
containing a minimum of 7.5 lbs (3.4 kg) refrigerant. The test is as 
follows:
    a. Weigh the tank at the start of the test, on a scale accurate to 
plus/minus 3 grams, to ensure it contains sufficient refrigerant.
    b. Operate the machine to remove refrigerant from the tank, charging 
into a holding container until the tank is indicated to be empty. 
Continue with the marketer's recommended procedure for the 2% 
capability.
    c. Weigh the tank, on a scale accurate to plus/minus 3 grams.
    d. Using the recovery compressor and/or a vacuum pump, draw the tank 
into a vacuum of 9 to 10 inches Mercury (225 to 250 mm Mercury). The 
tank must hold that vacuum with a decay of less than 10% in 10 minutes. 
If vacuum decays 10% or more, the procedure shall be repeated as 
necessary to ensure the tank is empty.
    e. Weigh the tank on a scale accurate to plus/minus 3 grams. The 
difference in weight from Steps 3 to 5 shall be within 2% of the weight 
of the amount of refrigerant that is the tanks rated capacity.
    f. This test may be performed at the conclusion of testing in 10.4 
or 10.5. If the machine passes or has passed all other testing in this 
standard, the marketer may make modifications in procedure and/or 
machine operation and retest once at a later date, within 90 days. If 
the machine fails the retest, the machine must be completely retested 
per this standard, or may be certified per the following alternative. 
The marketer of the machine may specify use of a non-refillable 
refrigerant tank that provides for recycling and/or disposal of the 
residual refrigerant, in either case in a manner that does not vent. Or 
the marketer may exclude use of a one-way container, in the machine's 
operating instructions.
    7.4 All flexible hoses must comply with SAE J2196.
    7.5 Service hoses must have shutoff devices located at the 
connection point to the system being serviced. Any hoses or lines 
connected to refrigerant containers on or in the machine also shall have 
shutoff devices at the connection points, so that the containers may be 
changed without loss of refrigerant. A tank that is a permanent 
installation is exempt from this requirement.
    7.6 The equipment shall separate oil from the refrigerant, measure 
the amount accurate to 20 ml (0.7 oz.), so the technician has an 
accurate basis for adding oil to the system.
    7.6.1 This statement shall be predominately identified in the 
equipment service manual.

    Note: Use only new lubricant to replace the amount removed during 
the recycling process. Used lubricant should be discarded per applicable 
federal, state and local requirements.

                               8. Testing

    This test procedure and its requirements are to be used to determine 
the ability of the recycling equipment to adequately recycle

lubricant, and 1000 ppm (by weight) of noncondensable gases (air).
    8.3.1.1 The HFC-134a compatible lubricant referred to in 8.3.1, 
shall be polyalkylene glycol (PAG), ISO 100 such as UCLN or PAG ISO 46-
55, such as Idemitsu or equivalent, which shall contain no more than 
1000 ppm by weight of moisture.
    8.3.1.2 Although the test lubricant is a PAG, to conform to that 
used in the test vehicle system, the equipment manufacturer also shall 
ensure that it is compatible with polyol ester lubricant, such as ND 11 
as used in electrically driven compressors in some hybrid vehicles.

                             8.4 Test Cycle

    8.4.1 The equipment must be preconditioned by processing 13.6 kg (30 
lb) of the standard contaminated HFC-134a at an ambient of 21 to 24

as defined in 8.4.

               8.7 Quantitative Determination of Moisture

    8.7.1 The recycled liquid phase sample of HFC-134a shall be analyzed 
for moisture content via Karl Fischer coulometric titration, or an 
equivalent method. The Karl Fischer apparatus is an instrument for 
precise determination of small amounts of water dissolved in liquid and/
or gas samples.
    8.7.2 In conducting this test, a weighed sample of 30 to 130 g is 
vaporized directly into the Karl Fischer anolyte. A coulometric 
titration is conducted and the results are reported as parts per million 
moisture (weight).
    8.8 Determination of Percent Lubricant 8.8.1 The amount of lubricant 
in the recycled HFC-134a sample shall be determined via gravimetric 
analysis. The methodology must account for the hygroscopicity of the 
lubricant.
    8.8.2 Following venting of noncondensable gases in accordance with 
the manufacturer's operating instructions, the refrigerant container 
shall be shaken for 5 min prior to extracting samples for testing.
    8.8.3 A weighed sample of 175 to 225 g of liquid HFC-134a is allowed 
to evaporate at room temperature. The percent lubricant is calculated 
from weights of the original sample and the residue remaining after 
evaporation.

              8.9 Noncondensable Gases--Testing for Amount

    8.9.1 The amount of noncondensable gases shall be determined by gas 
chromatography. A sample of vaporized refrigerant liquid shall be 
separated and analyzed by gas chromatography. A Porapak Q column at 130 
[deg]C (266 [deg]F) and a hot wire detector may be used for the 
analysis.
    8.9.2 This test shall be conducted on liquid phase samples of 
recycled refrigerant taken from a full container as defined in 7.2 
within 30 min following the proper venting of noncondensable gases.
    8.9.3 The liquid phase samples in 8.9.2 shall be vaporized 
completely prior to gas chromatographic analysis.
    8.9.4 This test shall be conducted at 10 and 49 [deg]C (50 and 120 
[deg]F) and may be performed in conjunction with the testing defined in 
8.6. The equipment shall process at least 13.6 kg (30 lb) of standard 
contaminated refrigerant for this test.
    8.9.5 The equipment shall be capable of charging refrigerant into 
systems with various lubrication types and shall deliver less than 1% by 
weight residual oil during system charge if the machine permits oil 
charging with refrigerant (due to residual oil in the service hoses and 
recovery unit refrigerant circuit from prior recovery, diagnostics and 
oil injection. This shall be determined during SAE J2099 testing.)

                        9. Recharging the System

    9.1 It is the responsibility of the equipment manufacturer to ensure 
that the vacuum removal performance leaves the system 98% free of NCGs 
before recharging, following recovery and recycle under the provisions 
of this document.
    The equipment must be capable of both indicating and recharging the 
system to within 15 g (0.50 oz) of vehicle manufacturer's 
specifications. The laboratory shall test for this capability by 
choosing a charge amount that is within the range of the vehicle 
manufacturer's specifications. The equipment must indicate and charge 
the system with that chosen amount, within 15 g 
(0.5 oz).
    Example: If 500 g is chosen, the actual and indicated charge must be 
485 to 515 g, with any difference between actual and indicated charge 
within the laboratory scale accuracy requirements of this standard. If a 
scale is used in the machine, the equipment manufacturer shall provide a 
method or service for the technician to check scale accuracy, and 
include any necessary accuracy-checking device (such as a calibration 
weight(s)) with the machine. If a mass flow system is used for charge 
determination, it must maintain accuracy equal to the 15 g (0.50 oz) 
specification. The equipment manufacturer shall provide a method for 
checking accuracy and include any necessary accuracy testing device(s) 
with the machine. If the accuracy testing device(s) for a scale or mass 
flow machine includes a consumable, the manufacturer shall include a 
quantity of replacement or refill devices for five years of periodic 
testing as recommended.
    9.2 If any other system is used for charge determination, such as a 
positive displacement pump, the equipment manufacturer shall provide a 
method and any needed device(s) to check accuracy that is/are 
appropriate for its method of operation, including any temperature-
compensating trim if used.

 10. Equipment Test Procedure by Laboratory for Recovery/Recycling and 
                 Recovery/Recycling/Recharging Machines

    10.1 Preliminary: Ambient (in shop) temperature shall be 21 to 24 
[deg]C (70 to 75 [deg]F). Test vehicle shall be ``overnight cold'' (not 
run for at least eight hours).
    10.2 The machine must have a self-contained provision for checking 
accuracy of

[[Page 100]]

the indicated amount of refrigerant recovered in liquid or vapor or 
mixture form(s) from a vehicle system and (if applicable) charged into a 
vehicle, and adjusting if necessary, to meet requirements of 9.1, 9.2. 
Therefore: If the machine uses a scale for that purpose, check the 
accuracy of that scale and make any adjustment if necessary. If an 
alternative method of measuring refrigerant is used, follow the 
equipment manufacturer's procedure for ensuring accuracy. Next, move the 
machine, such as by rolling it, along the floor, a minimum of 20 feet 
(6.1 meters) within 10 seconds. Follow with the test procedure in 10.3, 
then 10.4 or 10.5.

                           10.3 Test Procedure

    If desired, this test procedure may be preceded by engine/system 
operation for up to 15 minutes, up to 2000 rpm.
    1. You must start with an empty system, using this method: (a) 
Operate machine to recover refrigerant, per equipment manufacturer's 
instructions. (b) Deep-vacuum system to a minimum of 710 mm (28 in) of 
mercury. (c) Monitor vacuum for decay, checking every 20 minutes. If 
decay exceeds 75 mm (3 in), deep vacuum the system again. When system 
holds 710 mm (28 in) 75 mm (3 in) of mercury vacuum for three hours, it 
is considered empty.
    2. Place machine on a platform scale with the capacity to weigh the 
recovery/recycle/recharge machine, and with the resolution and accuracy 
of within 3 g (.006 lb) in the range of the 
machine's weight. Weight should include the machine's service hoses 
draped over the machine, and with the machine's oil reservoir removed. 
If necessary to add oil to vehicle system as a result of a system 
operation preparatory to the recovery process, inject the needed 
quantity through the service valve at this time.
    3. Record weight of machine in as weight A.
    4. Reconnect service hoses to the test vehicle.
    5. Follow the equipment manufacturer's specified procedure for 
charging the vehicle manufacturer's recommended amount of refrigerant 
into the system. Note: if this does not apply to the machine under test, 
i.e. a recovery/recycling only machine, the use of charging equipment 
that meets this standard and the platform scale shall be used to verify 
the accuracy of the charge.
    6. Disconnect the service hoses from the test vehicle and drape them 
on the machine. Check and record the weight of the machine. Record this 
weight as weight B. The difference between weight A and weight B should 
be equal to the recommended charge that was installed per the machine's 
display, within 15 g (0.5 oz). If the difference is greater than 15 g 
(3 g), the machine fails the charge accuracy test, 
and no other tests shall be performed at that time. The manufacturer 
must document changes made to improve accuracy and furnish them to the 
laboratory prior to a new test. Exception: If the maximum deviation is 
no more than a total of 20 g, the calibration of the scale or other 
measuring system may be rechecked and readjusted once, and the entire 
test repeated just once.

                   10.4 Recovery Test Using a Vehicle

    1. Following a successful system charge, the system and engine shall 
be run for 15 minutes at 2000 rpm to circulate oil and refrigerant, 
following which engine and system shall rest for eight hours. Then the 
laboratory may begin the recovery test. If the machine manufacturer 
specifies, operate the engine/system for up to 15 minutes, at up to 2000 
rpm, then shut off engine/system.
    2. If the machine has an automatic air purge, disable it. Check the 
weight of the machine with the platform scale (service hoses draped over 
machine, oil reservoir removed). Record the number as Weight C. 
Reinstall oil reservoir if it had been removed in the recovery 
procedure.
    3. Start timer. Connect service hoses to system of test vehicle and 
perform recovery per the equipment manufacturer's instructions. The 
vehicle system service valves' cores must remain in the fittings for 
this procedure.
    4. When recovery is completed, including from service hoses if that 
is part of the recommended procedure, disconnect hoses and drape over 
machine. Stop timer. The elapsed time shall be 30.0 minutes or less. If 
it is in excess of this time, the machine fails the test and no retest 
is allowed. The manufacturer must document changes made to the machine 
to improve its performance before a new test is allowed, and furnish 
them to the laboratory.
    5. If the recovery is completed in no more than the 30.0 minutes, 
measure the oil level in the reservoir, remove the reservoir and then 
determine the amount of refrigerant recovered, as detailed in Nos. 6 and 
7: As measured by the machine and also by noting the weight of the 
platform scale, which shall be recorded as Weight D.
    6. The platform scale shall indicate that a minimum of 95% of the 
amount charged into the system has been recovered. If the platform scale 
indicates a lower percentage has been recovered, the machine fails the 
recovery test.
    7. The machine display shall indicate that a minimum of 95.0% of the 
amount charged into the system has been recovered, within a tolerance of 
30 g (1 oz) when compared with the platform scale 
(Weight D minus Weight C). The 30 g (1 oz) tolerance may produce a 
machine display reading that is below the 95.0% recovery. If a greater 
difference between machine and platform scale occurs, the machine fails 
the recovery test.

                 10.5 Recovery Test Fixture Test Option

    If an equipment manufacturer chooses, as an alternative to the 
actual vehicle, it may certify to SAE J2788 with a laboratory fixture 
that is composed entirely of all the original equipment parts of a 
single model year for the 3.0 lb capacity front/rear A/C system in the 
2005-07 Chevrolet Suburban. All parts must be those OE-specified for one 
model year system and no parts may be eliminated or bypassed from the 
chosen system, or reproduced by a non-OE source. No parts may be added 
and/or relocated from the OE position in the 2005-07 Suburban. No parts 
may be modified in any way that could affect system performance for 
testing under this standard, except adding refrigerant line bends and/or 
loops to make the system more compact. Reducing the total length of the 
lines, however, is not permitted. The fixture system shall be powered by 
an electric motor, run at a speed not to exceed 2000 rpm, and for this 
test option, no system warm-up or equivalent procedure may be used. The 
certifying laboratory shall maintain records of all parts purchased, 
including invoices and payments. The assembly of the parts shall, as an 
outside-the-vehicle package, duplicate the OE system and its routing, 
including bends, except for permitted additions of bends and/or loops in 
refrigerant lines. Aside from the absence of engine operation and the 
limitations posed by the standard and the use of the electric motor, the 
test shall otherwise be the same as the test on the Suburban, including 
test temperature.

Sec. Appendix D to Subpart B of Part 82--SAE J2810 Standard for Recovery 
                 Only Equipment for HFC-134a Refrigerant

                                Foreword

    This Appendix establishes the specific minimum equipment 
requirements for the recovery of HFC-134a that has been directly removed 
from, motor vehicle air-conditioning systems.

                                1. Scope

    The purpose of this SAE Standard is to provide minimum performance 
and operating feature requirements for the recovery of HFC-134a (R-134a) 
refrigerant to be returned to a refrigerant reclamation facility that 
will process it to the appropriate ARI 700 Standard or allow for 
recycling of the recovered refrigerant to SAE J2788 specifications by 
using SAE J2788-certified equipment. It is not acceptable that the 
refrigerant removed from a mobile air-conditioning (A/C) system with 
this equipment be directly returned to a mobile A/C system.
    This information applies to equipment used to service automobiles, 
light trucks, and other vehicles with similar HFC-134a (R-134a) A/C 
systems.
    1.1 Improved refrigerant recovery equipment is required to ensure 
adequate refrigerant recovery to reduce emissions and provide for 
accurate recharging of mobile air conditioning systems. Therefore, 12 
months following the publication date of this standard, it supersedes 
SAE J1732.

                         6. Function Description

    6.1 The equipment must be capable of continuous operation in ambient 
temperatures of 10 [deg]C (50 [deg]F) to 49 [deg]C (120 [deg]F). 
Continuous is defined as completing recovery operation with no more than 
a brief reset between servicing vehicles, and shall not include time 
delays for allowing a system to outgas (which shall be part of the 
recovery period provided by this standard).
    6.1.1 The equipment shall demonstrate ability to recovery a minimum 
of 95.0% of the refrigerant from the test vehicle in 30.0 minutes or 
less, without prior engine operation (for previous eight hours minimum), 
external heating or use of any device (such as shields, reflectors, 
special lights, etc.), which could heat components of the system.

[[Page 103]]

The recovery procedure shall be based on a test at 21 [deg]C to 24 
[deg]C (70 [deg]F to 75 [deg]F) ambient temperature. The test system for 
qualifying shall be a 1.4 kg (3.0 lbs) capacity orifice tube/accumulator 
system in a 2005-07 Chevrolet Suburban with front and rear A/C or the 
test option described in section 9.
    6.1.2 The equipment shall demonstrate ability to recover a minimum 
of 85% of the refrigerant from the test vehicle or system of 6.1.1. in 
30.0 minutes or less, at an ambient temperature of 10 [deg]C to 13 
[deg]C (50 [deg]F to 55 [deg]F), subject to the same restrictions 
regarding engine operation and external heating.
    6.1.3 During recovery operation, the equipment shall provide 
overfill protection so that the liquid fill of the storage container 
does not exceed 80% of the tank's rated volume at 21 [deg]C (70 [deg]F). 
This will ensure that the container meets Department of Transportation 
(DOT) Standard, CFR Title 49, section 173.304 and the American Society 
of Mechanical Engineers.
    6.1.4 Portable refillable tanks or containers used in conjunction 
with this equipment must be labeled ``HFC-134a (R-134a) and meet 
applicable Department of Transportation (DOT) or Underwriters 
Laboratories (UL) Standards, and incorporate fittings per SAE J2197.
    6.1.5 The cylinder valves shall comply with the standard for 
cylinder valves UL 1769.
    6.1.6 The pressure relief device shall comply with the Pressure 
Relief Device Standard Part 1--Cylinders for Compressed Gasses CGA 
Pamphlet S-1.1.
    6.1.7 The tank assembly shall be marked to indicate the first retest 
date, which shall be five years from the date of manufacture. The 
marking shall indicate that retest must be performed every subsequent 
five years. SAE J2296 provides an inspection procedure. The marking 
shall be in letters at least 6 mm (0.25 in) high. If ASME tanks, as 
defined in UL-1963, are used, they are exempt from the retest 
requirements.
    6.2 If the marketer permits use of a refillable refrigerant tank, a 
method must be provided (including any necessary fittings) for transfer 
to a system that ensures proper handling (recycling or other, 
environmentally-legal disposal).
    Restricting the equipment to use of non-refillable tanks eliminates 
compliance with this provision.
    6.3 Prior to testing under this standard, the equipment must be 
preconditioned with a minimum of 13.6 kg of the standard contaminated 
HFC-134a (R-134a) at an ambient of 21 [deg]C before starting the test 
cycle. Sample amounts are not to exceed 1.13 kg with sample amounts to 
be repeated every 5 min. The test fixture shown in Figure 1 shall be 
operated at 21 [deg]C. Contaminated HFC-134a (R-134a) samples shall be 
processed at ambient temperatures of 10 [deg]C and 49 [deg]C (50 [deg]F 
to 120 [deg]F), without the equipment shutting down due to any safety 
devices employed in this equipment.
    6.3.1 Contaminated HFC-134a (R-134a) sample shall be standard 
contaminated HFC-134a (R-134a) refrigerant, 13.6 kg sample size, 
consisting of liquid HFC-134a (R-134a) with 1300 ppm (by weight) 
moisture at 21 [deg]C (70 [deg]F) and 45 000 ppm (by weight) of oil 
(polyalkylene glycol oil with 46-160 cst viscosity at 40 [deg]C) and 
1000 ppm by weight of noncondensable gases (air).
    6.3.2 Portable refillable containers used in conjunction with this 
equipment must meet applicable DOT Standards. The color of the container 
must be blue with a yellow top to indicate the container holds used HFC-
134a (R-134a) refrigerant. The container must be permanently marked on 
the outside surface in black print at least 20 mm high, ``CONTAMINATED 
HFC-134a (R-134a)--DO NOT USE, MUST BE REPROCESSED.''

                         Figure 1--Test Fixture

    6.3.3 The portable refillable container shall have a \1/2\ in ACME 
thread.
    6.4 Additional Storage Tank Requirements.
    6.4.1 The cylinder valve shall comply with UL 1769.
    6.4.2 The pressure relief device shall comply with CGA Pamphlet S-
1.1.
    6.5 All flexible hoses must meet SAE J2196 for service hoses.
    6.6 Service hoses must have shutoff devices located at the 
connection points to the system being serviced to minimize introduction 
of noncondensable gases into the recovery equipment during connection 
and the release of the refrigerant during disconnection.
    6.7 The equipment must be able to separate the lubricant from 
recovered refrigerant and accurately indicate the amount removed from 
the simulated automotive system during processing in 20 mL (0.7 fl oz) 
units.
    6.7.1 The purpose of indicating the amount of lubricant removed is 
to ensure that a proper amount of new lubricant is returned to the 
mobile A/C system for compressor lubrication, if the system is to be 
charged with equipment meeting SAE J2788.
    6.7.2 Refrigerant dissolved in this lubricant must be accounted for 
to prevent lubricant overcharge of the mobile A/C system.
    6.8 The equipment must be capable of continuous operation in ambient 
temperatures of 10 [deg]C to 49 [deg]C (50 [deg]F to120 [deg]F) and 
comply with 6.1 to 6.4 of this standard.
    6.9 For test validation, the equipment is to be operated according 
to the manufacturer's instructions.
    7. Test Procedure A at 21 [deg]C to 24 [deg]C (70 [deg]F to 75 
[deg]F).
    The test vehicle (2005-2007 Chevrolet Suburban with rear A/C 
system--1.4 kg/ 3.0 lb) or laboratory fixture per section 10.5 of SAE

[[Page 104]]

J2788, shall be prepared as for SAE J2788, section 10.3, following Steps 
1, 2, 3, 4, and then the following:
    7.1 Using a machine certified to SAE J2788 and with the machine on a 
platform scale with accuracy to within plus/minus 3.0 grams at the 
weight of the machine, charge the system to the vehicle manufacturer's 
recommended amount of refrigerant (1.4 kg-3.0 lb). The actual charge 
amount per the reading on the platform scale shall be used as the basis 
for the recovery efficiency of the recovery-only machine being tested to 
this standard. Run the engine (or operate test fixture with electric 
motor) for up to 15 minutes at up to 2000 rpm to circulate oil and 
refrigerant. The system then must rest for eight hours.
    7.2 Place the recovery machine on the platform scale and record the 
weight with the hoses draped over the machine. Ambient temperature shall

that is part of the recommended procedure, disconnect the hoses and 
drape over the machine. Stop the timer. The elapsed time shall be no 
more than 30 minutes.
    7.5 Remove the oil reservoir, empty and reinstall. The platform 
scale shall indicate that a minimum of 95.0% of the refrigerant has been 
recovered, based on the charge amount indicated by the platform scale. 
If the machine has recovered the minimum of 95.0% within the 30.0 
minutes, the next test shall be performed. If it fails this test, the 
marketer of the equipment must document changes to the equipment to 
upgrade performance before a retest is allowed. If it passes, the 
laboratory can proceed to Test Procedure B-10 [deg]C to 13 [deg]C (50 
[deg]F to 55 [deg]F).
    8. Test Procedure B at 10 [deg]C to 13 [deg]C (50 [deg]F to 55 
[deg]F).

(1.4 kg/3.0 lb) or test fixture per section 10.5 of SAE J2788, shall be 
prepared as per 7.0 and 7.1 of this standard, and then the following:
    8.1 Place the recovery machine on the platform scale and record the 
weight with the hoses draped over the machine.
    Ambient temperature at this time shall be no higher than 10 [deg]C 
to13 [deg]C (50 [deg]F to 55 [deg]F).
    8.2 Start the timer. Connect the service hoses to the system of the 
test vehicle and perform the recovery per the equipment manufacturer's 
instructions. This also shall be performed without the immediately prior 
engine operation permitted by SAE J2788, section 10.4, Step No. 1. The 
vehicle system's service valve cores must remain in the fittings for 
this procedure.
    8.3 When recovery is completed, including from the service hoses if 
that is part of the recommended procedure, disconnect the hoses and 
drape over the machine. Stop the timer. The elapsed time shall be no 
more than 30 minutes.
    8.4 Remove the oil reservoir, empty and reinstall. The platform 
scale shall indicate that a minimum of 85.0% of the refrigerant has been 
recovered, based on the charge amount indicated by the platform scale. 
If the machine has recovered the minimum of 85.0% within the 30 minutes, 
it has passed the test procedure and if it meets all other requirements 
of this standard, it is certified.

                             9. Test Option

    As in SAE J2788, Section 10.5, as an alternative to a 2005-2007 
Chevrolet Suburban with rear A/C (1.4 kg-3.0 lb) system, a laboratory 
test fixture may be used to certify to SAE J2810 the fixture must be 
composed entirely of all the original equipment parts of a single model 
year for the 1.4 kg (3.0 lb) capacity system. All parts must be those 
OE-specified for one model year system and no parts may be eliminated or 
bypassed from the chosen system or reproduced from a non-OE source. No 
parts may be added and/or relocated from the OE position in the 2005-07 
Suburban. No parts may be modified in any way that could affect system 
performance for testing under this standard, except adding refrigerant 
line bends and/or loops to make the system more compact. Reducing the 
total length of the lines, however, is not permitted.
    The fixture systems for this standard shall not be powered by an 
electric motor during recovery, although a motor can be used, run at a 
speed not to exceed 2000 rpm, as part of the preparatory process, 
including installation of the charge.

protection to assure that during filling or transfer, the tank or 
storage container cannot exceed 80% of volume at 21.1 [deg]C of its 
maximum rating as defined by DOT standards, 49 CFR 173.304 and American 
Society of Mechanical Engineers.

[[Page 107]]

    7.5 Hoses and Connections
    7.5.1 Separate inlet and outlet hoses with fittings and separate 
connections shall be provided for each refrigerant circuit.
    7.5.2 All flexible hoses and fittings must meet SAE J2196 (for CFC-
12) and SAE J2197 (for HFC-134a).
    7.5.3 Service hoses must have shutoff devices located within 30 cm 
of the connection point to the system being serviced.
    7.6 Lubricant Separation
    7.6.1 The equipment must be able to separate the lubricant from the 
removed refrigerant and accurately indicate the amount of lubricant 
removed during the process, in 30 mL (1 fl oz) units. Refrigerant 
dissolves in lubricant and, as a result, increases the volume of the 
recovered lubricant sample. This creates the illusion that more 
lubricant has been recovered that actually has been. The equipment 
lubricant measuring system must take into account such dissolved 
refrigerant removed from the A/C system being serviced to prevent 
overcharging the vehicle system with lubricant.

    (Note: Use only new lubricant to replace the amount removed the 
recycling process. Used lubricant should be discarded per applicable 
federal, state and local requirements.)

    7.6.2 The equipment must be provided with some means, such as a 
lockout device, which will prevent initiation of the recovery operation 
after switching to the other refrigerant, if the lubricant has not been 
drained from the oil separator.

                               8. Testing

that fittings shall be unique to the applicable refrigerant.
    6.6 Service hoses must have shutoff devices located within 30 cm of 
the connection point to the system being serviced to minimize 
introduction of noncondensable gases into the recovery equipment during 
connection and the release of the refrigerant during disconnection.
    6.7 The equipment must be able to separate the lubricant from the 
recovered refrigerant and accurately indicate the amount removed from 
the simulated automotive system during processing in 30 mL units.
    6.7.1 The purpose of indicating the amount of lubricant is to ensure 
that a proper amount of new lubricant is returned to the mobile air 
conditioning system for compressor lubrication.
    6.7.2 Refrigerant dissolved in this lubricant must be accounted for 
to prevent system lubricant overcharge of the mobile air-conditioning 
system.
    6.8 The equipment must be capable of continuous operation in 
temperatures of 10 to 49 [deg]C and must comply with 6.1 and 6.2.

(b) shall bear the following warning statement, meeting the requirements 
of this subpart for placement and form:

    WARNING: Contains [or Manufactured with, if applicable] [insert name 
of substance], a substance which harms public health and environment by 
destroying ozone in the upper atmosphere.
    (2) Each container of fire suppression agent containing HCFC-123 
produced or imported on or after January 1, 2020

[[Page 120]]

shall bear the following warning statement, meeting the requirements of 
this subpart for placement and form:
    WARNING: Contains [insert name of substance], a substance which 
harms public health and environment by destroying ozone in the upper 
atmosphere. Use Only for Recharge of Equipment Manufactured before 
January 1, 2020.
    (3) Each container of fire suppression agent containing reclaimed 
HCFC-123 or HCFC-123 that was imported prior to January 1, 2020, shall 
bear the following warning statement, meeting the requirements of this 
subpart for placement and form:
    WARNING: Contains [insert name of substance], a substance which 
harms public health and environment by destroying ozone in the upper 
atmosphere. For use in any equipment.

    (b) Exemptions from warning label requirement. The following 
products need not bear a warning label:
    (1) Products containing trace quantities of a controlled substance 
remaining as a residue or impurity due to a chemical reaction, and where 
the controlled substance serves no useful purpose in or for the product 
itself. However, if such product was manufactured using the controlled 
substance, the product is required to be labeled as a ``product 
manufactured with'' the controlled substance, unless otherwise exempted;
    (2) Containers containing a controlled substance in which trace 
quantities of that controlled substance remain as a residue or impurity;
    (3) Waste containing controlled substances or blends of controlled 
substances bound for discard;
    (4) Products manufactured using methyl chloroform or CFC-113 by 
persons who can demonstrate and certify a 95% reduction in overall usage 
from their 1990 calendar year usage of methyl chloroform or CFC-113 as 
solvents during a twelve (12) month period ending within sixty (60) days 
of such certification or during the most recently completed calendar 
year. In calculating such reduction, persons may subtract from 
quantities used those quantities for which they possess accessible data 
that establishes the amount of methyl chloroform or CFC-113 transformed. 
Such subtraction must be performed for both the applicable twelve month 
period and the 1990 calendar year. If at any time future usage exceeds 
the 95% reduction, all products manufactured with methyl chloroform or 
CFC-113 as solvents by that person must be labeled immediately. No 
person may qualify for this exemption after May 15, 1994;
    (5) Products intended only for export outside of the United States 
shall not be considered ``products introduced into interstate commerce'' 
provided such products are clearly designated as intended for export 
only;
    (6) Products that are otherwise not subject to the requirements of 
this subpart that are being repaired, using a process that uses a 
controlled substance.
    (7) Products, processes, or substitute chemicals undergoing research 
and development, by which a controlled substance is used. Such products 
must be labeled when they are introduced into interstate commerce.
    (c) Interference with other required labeling information. The 
warning statement shall not interfere with, detract from, or mar any 
labeling information required on the labeling by federal or state law.

[60 FR 4020, Jan. 19, 1995, as amended at 85 FR 15300, Mar. 17, 2020]



Sec.82.108  Placement of warning statement.

    The warning statement shall be placed so as to satisfy the 
requirement of the Act that the warning statement be ``clearly legible 
and conspicuous.'' The warning statement is clearly legible and 
conspicuous if it appears with such prominence and conspicuousness as to 
render it likely to be read and understood by consumers under normal 
conditions of purchase. Such placement includes, but is not limited to, 
the following:
    (a) Display panel placement. For any affected product or container 
that has a display panel that is normally viewed by the purchaser at the 
time of the purchase, the warning statement described in Sec.82.106 
may appear on any such display panel of the affected product or 
container such that it is ``clearly legible and conspicuous'' at the 
time

[[Page 121]]

of the purchase. If the warning statement appears on the principal 
display panel or outer packaging of any such affected product or 
container, the warning statement shall qualify as ``clearly legible and 
conspicuous,'' as long as the label also fulfills all other requirements 
of this subpart and is not obscured by any outer packaging, as required 
by paragraph (b) of this section. The warning statement need not appear 
on such display panel if either:
    (1) The warning statement appears on the outer packaging of the 
product or container, consistent with paragraph (b) of this section, and 
is clearly legible and conspicuous; or
    (2) The warning statement is placed in a manner consistent with 
paragraph (c) of this section.
    (b) Outer packaging. If the product or container is normally 
packaged, wrapped, or otherwise covered when viewed by the purchaser at 
the time of the purchase the warning statement described in Sec.82.106 
shall appear on any outer packaging, wrapping or other covering used in 
the retail display of the product or container, such that the warning 
statement is clearly legible and conspicuous at the time of the 
purchase. If the outer packaging has a display panel that is normally 
viewed by the purchaser at the time of the purchase, the warning 
statement shall appear on such display panel. If the warning statement 
so appears on such product's or container's outer packaging, it need not 
appear on the surface of the product or container, as long as the 
statement also fulfills all other requirements of this subpart. The 
warning statement need not appear on such outer packaging if either:
    (1) The warning statement appears on the surface of the product or 
container, consistent with paragraph (a) of this section, and is clearly 
legible and conspicuous through any outer packaging, wrapping or other 
covering used in display; or
    (2) The warning statement is placed in a manner consistent with 
paragraph (c) of this section.
    (c) Alternative placement. The warning statement may be placed on a 
hang tag, tape, card, sticker, invoice, bill of lading, supplemental 
printed material, or similar overlabeling that is securely attached to 
the container, product, outer packaging or display case, or accompanies 
the product containing or manufactured with a controlled substance or a 
container containing class I or class II substances through its sale to 
the consumer or ultimate consumer. For prescription medical products 
that have been found to be essential for patient health by the Food and 
Drug Administration, the warning statement may be placed in supplemental 
printed material intended to be read by the prescribing physician, as 
long as the following statement is placed on the product, its packaging, 
or supplemental printed material intended to be read by the patient: 
``This product contains [insert name of substance], a substance which 
harms the environment by depleting ozone in the upper atmosphere.'' In 
any case, the warning statement must be clearly legible and conspicuous 
at the time of the purchase.
    (d) Products not viewed by the purchaser at the time of purchase. 
Where the purchaser of a product cannot view a product, its packaging or 
alternative labeling such that the warning statement is clearly legible 
and conspicuous at the time of purchase, as specified under paragraphs 
(a), (b), or (c) of this section, the warning statement may be placed in 
the following manner:
    (1) Where promotional printed material is prepared for display or 
distribution, the warning statement may be placed on such promotional 
printed material such that it is clearly legible and conspicuous at the 
time of purchase; or
    (2) The warning statement may be placed on the product, on its outer 
packaging, or on alternative labeling, consistent with paragraphs (a), 
(b), or (c) of this section, such that the warning statement is clearly 
legible and conspicuous at the time of product delivery, if the product 
may be returned by the purchaser at or after the time of delivery or if 
the purchase is not complete until the time of delivery (e.g., products 
delivered C.O.D.).

[[Page 122]]



Sec.82.110  Form of label bearing warning statement.

    (a) Conspicuousness and contrast. The warning statement shall appear 
in conspicuous and legible type by typography, layout, and color with 
other printed matter on the label. The warning statement shall appear in 
sharp contrast to any background upon which it appears. Examples of 
combinations of colors which may not satisfy the proposed requirement 
for sharp contrast are: black letters on a dark blue or dark green 
background, dark red letters on a light red background, light red 
letters on a reflective silver background, and white letters on a light 
gray or tan background.
    (b) Name of substance. The name of the class I or class II substance 
to be inserted into the warning statement shall be the standard chemical 
name of the substance as listed in 40 CFR part 82, appendix A to subpart 
A, except that:
    (1) The acronym ``CFC'' may be substituted for 
``chlorofluorocarbon.''
    (2) The acronym ``HCFC'' may be substituted for 
``hydrochlorofluorocarbon.''
    (3) The term ``1,1,1-trichloroethane'' may be substituted for 
``methyl chloroform.''
    (c) Combined statement for multiple controlled substances. If a 
container containing or a product contains or is manufactured with, more 
than one class I or class II substance, the warning statement may 
include the names of all of the substances in a single warning 
statement, provided that the combined statement clearly distinguishes 
which substances the container or product contains and which were used 
in the manufacturing process.
    (d) Format. (1) The warning statement shall be blocked within a 
square or rectangular area, with or without a border. (2) The warning 
statement shall appear in lines that are parallel to the surrounding 
text on the product's PDP, display panel, supplemental printed material 
or promotional printed material.
    (e) Type style. The ratio of the height of a capital letter to its 
width shall be such that the height of the letter is no more than 3 
times its width; the signal word ``WARNING'' shall appear in all capital 
letters.
    (f) Type size. The warning statement shall appear at least as large 
as the type sizes prescribed by this paragraph. The type size refers to 
the height of the capital letters. A larger type size materially 
enhances the legibility of the statement and is desirable.
    (1) Display panel or outer packaging. Minimum type size requirements 
for the warning statement are given in Table 1 to this paragraph and are 
based upon the area of the display panel of the product or container. 
Where the statement is on outer packaging, as well as the display panel 
area, the statement shall appear in the same minimum type size as on the 
display panel.

Sec.82.112  Removal of label bearing warning statement.

    (a) Prohibition on removal. Except as described in paragraph (b) or 
(c) of this section, any warning statement that accompanies a product or 
container introduced into interstate commerce, as required by this 
subpart, must remain with the product or container and any product 
incorporating such product or container, up to and including the point 
of sale to the ultimate consumer.
    (b) Incorporation of warning statement by subsequent manufacturers. 
A manufacturer of a product that incorporates a product that is 
accompanied by a label bearing the warning statement may remove such 
label from the incorporated product if the information on such label is 
incorporated into a warning statement accompanying the manufacturer's 
product, or if, pursuant to paragraph (c) of this section, the 
manufacturer of the product is not required to pass through the 
information contained on or incorporated in the product's label.
    (c) Manufacturers that incorporate products manufactured with 
controlled substances. A manufacturer that incorporates into its own 
product a component product that was purchased from another 
manufacturer, was manufactured with a process that uses a controlled 
substance(s), but does not contain such substance(s), may remove such 
label from the incorporated product and need not apply a warning 
statement to its own product, if the manufacturer does not use a 
controlled substance in its own manufacturing process. A manufacturer 
that uses controlled substances in its own manufacturing process, and is 
otherwise subject to the regulations of this subpart, must label 
pursuant to Sec.82.106, but need not include information regrading the 
incorporated product on the required label.
    (d) Manufacturers, distributors, wholesalers, retailers that sell 
spare parts manufactured with controlled substances solely for repair. 
Manufacturers, distributors, wholesalers, and retailers that purchase 
spare parts manufactured with a class I or class II substance from 
another manufacturer or supplier, and sell such spare parts for the sole 
purpose of repair, are not required to pass through an applicable 
warning label if such products are removed from the original packaging 
provided by the manufacturer from whom the products are purchased. 
Manufacturers of the spare parts manufactured with controlled substances 
must still label their products; furthermore, manufacturers, importers, 
and distributors of such products must pass through the labeling 
information as long as products remain assembled and packaged in the 
manner assembled and packaged by the original manufacturer. This 
exemption shall not apply if a spare part is later used for manufacture 
and/or for purposes other than repair.

Sec.82.114  Compliance by manufacturers and importers with 
requirements for labeling of containers of controlled substances, 
or products containing controlled substances.
          

    (a) Compliance by manufacturers and importers with requirements for 
labeling of containers of controlled substances, or products containing 
controlled substances. Each manufacturer of a product incorporating 
another product or container containing a controlled substance, to which 
Sec.82.102 (a)(1), or, (a)(2) or (b)(1) applies, that is purchased or 
obtained from another manufacturer or supplier, is required to pass 
through and incorporate the labeling information that accompanies such 
incorporated product in a warning statement accompanying the 
manufacturer's finished product. Each importer of a product, or 
container containing a controlled substance, to which Sec.82.102 
(a)(1), (a)(2), or (b)(1) applies, including a component product or 
container incorporated into the product, that is purchased from a 
foreign manufacturer or supplier, is required to apply a label, or to 
ensure that a label has been properly applied, at the site of U.S. 
Customs clearance.
    (b) Reliance on reasonable belief. The manufacturer or importer of a 
product

[[Page 124]]

that incorporates another product container from another manufacturer or 
supplier may rely on the labeling information (or lack thereof) that it 
receives with the product, and is not required to independently 
investigate whether the requirements of this subpart are applicable to 
such purchased product or container, as long as the manufacturer 
reasonably believes that the supplier or foreign manufacturer is 
reliably and accurately complying with the requirements of this subpart.
    (c) Contractual obligations. A manufacturer's or importer's 
contractual relationship with its supplier under which the supplier is 
required to accurately label, consistent with the requirements of this 
subpart, any products containing a controlled substance or containers of 
a controlled substance that are supplied to the manufacturer or 
importer, is evidence of reasonable belief.



Sec.82.116  Compliance by manufacturers or importers incorporating
products manufactured with controlled substances.

    (a) Compliance by manufacturers or importers incorporating products 
manufactured with controlled substances, or importing products 
manufactured with controlled substances. Each manufacturer or importer 
of a product incorporating another product to which Sec.82.102 (a)(3) 
or (b)(2) applies, that is purchased from another manufacturer or 
supplier, is not required to pass through and incorporate the labeling 
information that accompanies such incorporated product in a warning 
statement accompanying the manufacturer's or importer's finished 
product. Importers of products to which Sec.82.102 (a)(3) or (b)(2) 
applies are required to apply a label, or to ensure that a label has 
been properly applied at the site of U.S. Customs clearance.
    (b) Reliance on reasonable belief. The importer of a product 
purchased or obtained from a foreign manufacturer or supplier, which 
product may have been manufactured with a controlled substance, may rely 
on the information that it receives with the purchased product, and is 
not required to independently investigate whether the requirements of 
this subpart are applicable to the purchased or obtained product, as 
long as the importer reasonably believes that there was no use of 
controlled substances by the final manufacturer of the product being 
imported.
    (c) Contractual obligations. An importer's contractual relationship 
with its supplier under which the supplier is required to accurately 
label, consistent with the requirements of this subpart, any products 
manufactured with a controlled substance that are supplied to the 
importer, or to certify to the importer whether a product was or was not 
manufactured with a controlled substance is evidence of reasonable 
belief.



Sec.82.118  Compliance by wholesalers, distributors and retailers.

    (a) Requirement of compliance by wholesalers, distributors and 
retailers. All wholesalers, distributors and retailers of products or 
containers to which this subpart applies are required to pass through 
the labeling information that accompanies the product, except those 
purchasing from other manufacturers or suppliers spare parts 
manufactured with controlled substances and selling those parts for the 
demonstrable sole purpose of repair.
    (b) Reliance on reasonable belief. The wholesaler, distributor or 
retailer of a product may rely on the labeling information that it 
receives with the product or container, and is not required to 
independently investigate whether the requirements of this subpart are 
applicable to the product or container, as long as the wholesaler, 
distributor or retailer reasonably believes that the supplier of the 
product or container is reliably and accurately complying with the 
requirements of this subpart.
    (c) Contractual obligations. A wholesaler, distributor or retailer's 
contractual relationship with its supplier under which the supplier is 
required to accurately label, consistent with the requirements of this 
subpart, any products manufactured with a controlled substance that are 
supplied to the wholesaler, distributor or retailer is evidence of 
reasonable belief.

of such appliances (including small appliances and motor vehicle air 
conditioners), refrigerant reclaimers, technician certifying programs, 
appliance owners and operators, manufacturers of appliances, 
manufacturers of recovery and/or recycling equipment, approved recovery 
and/or recycling equipment testing organizations, and persons buying, 
selling, or offering to sell class I, class II, or non-exempt substitute 
refrigerants.

[81 FR 82349, Nov. 11, 2016]



Sec.82.152  Definitions.

    Appliance means any device which contains and uses a class I or 
class II substance or substitute as a refrigerant and which is used for 
household or commercial purposes, including any air conditioner, motor 
vehicle air conditioner, refrigerator, chiller, or freezer. For a system 
with multiple circuits, each independent circuit is considered a 
separate appliance.
    Apprentice means any person who is currently registered as an 
apprentice in maintenance, service, repair, or disposal of appliances 
with the U.S. Department of Labor's Office of Apprenticeship (or a State 
Apprenticeship Council recognized by the Office of Apprenticeship). A 
person may only be an apprentice for two years from the date of first 
registering with that office.
    Approved equipment testing organization means any organization which 
has applied for and received approval from the Administrator pursuant to 
Sec.82.160.
    Batch means a single bulk cylinder of refrigerant after all 
reclamation has been completed prior to packaging or shipping to the 
market.
    Class I refers to an ozone-depleting substance that is listed in 40 
CFR part 82 subpart A, appendix A.
    Class II refers to an ozone-depleting substance that is listed in 40 
CFR part 82 subpart A, appendix B.
    Certified refrigerant recovery or recycling equipment means 
equipment manufactured before November 15, 1993, that meets the 
standards in Sec.82.158(c), (e), or (g); equipment certified by an 
approved equipment testing organization to meet the standards in Sec.
82.158(b), (d), or (f); or equipment certified pursuant to Sec.
82.36(a).
    Comfort cooling means the air-conditioning appliances used to 
provide cooling in order to control heat and/or humidity in occupied 
facilities including but not limited to residential, office, and 
commercial buildings. Comfort cooling appliances include but are not 
limited to chillers, commercial split systems, and packaged roof-top 
units.
    Commercial refrigeration means the refrigeration appliances used in 
the retail food and cold storage warehouse sectors. Retail food 
appliances include the refrigeration equipment found in supermarkets, 
convenience stores, restaurants and other food service establishments. 
Cold storage includes the refrigeration equipment used to store meat, 
produce, dairy products, and other perishable goods.
    Component means a part of the refrigerant circuit within an 
appliance including, but not limited to, compressors, condensers, 
evaporators, receivers, and all of its connections and subassemblies.
    Custom-built means that the industrial process equipment or any of 
its components cannot be purchased and/or installed without being 
uniquely designed, fabricated and/or assembled to satisfy a specific set 
of industrial process conditions.
    Disposal means the process leading to and including:
    (1) The discharge, deposit, dumping or placing of any discarded 
appliance into or on any land or water;
    (2) The disassembly of any appliance for discharge, deposit, dumping 
or placing of its discarded component parts into or on any land or 
water;
    (3) The vandalism of any appliance such that the refrigerant is 
released into the environment or would be released into the environment 
if it had not been recovered prior to the destructive activity;
    (4) The disassembly of any appliance for reuse of its component 
parts; or
    (5) The recycling of any appliance for scrap.
    Follow-up verification test means those tests that involve checking 
the repairs

[[Page 129]]

to an appliance after a successful initial verification test and after 
the appliance has returned to normal operating characteristics and 
conditions to verify that the repairs were successful. Potential methods 
for follow-up verification tests include, but are not limited to, the 
use of soap bubbles as appropriate, electronic or ultrasonic leak 
detectors, pressure or vacuum tests, fluorescent dye and black light, 
infrared or near infrared tests, and handheld gas detection devices.
    Full charge means the amount of refrigerant required for normal 
operating characteristics and conditions of the appliance as determined 
by using one or a combination of the following four methods:
    (1) Use of the equipment manufacturer's determination of the full 
charge;
    (2) Use of appropriate calculations based on component sizes, 
density of refrigerant, volume of piping, and other relevant 
considerations;
    (3) Use of actual measurements of the amount of refrigerant added to 
or evacuated from the appliance, including for seasonal variances; and/
or
    (4) Use of an established range based on the best available data 
regarding the normal operating characteristics and conditions for the 
appliance, where the midpoint of the range will serve as the full 
charge.
    High-pressure appliance means an appliance that uses a refrigerant 
with a liquid phase saturation pressure between 170 psia and 355 psia at 
104 [deg]F. Examples include but are not limited to appliances using R-
22, R-407A, R-407C, R-410A, and R-502.
    Industrial process refrigeration means complex customized appliances 
that are directly linked to the processes used in, for example, the 
chemical, pharmaceutical, petrochemical, and manufacturing industries. 
This sector also includes industrial ice machines, appliances used 
directly in the generation of electricity, and ice rinks. Where one 
appliance is used for both industrial process refrigeration and other 
applications, it will be considered industrial process refrigeration 
equipment if 50 percent or more of its operating capacity is used for 
industrial process refrigeration.
    Industrial process shutdown means when an industrial process or 
facility temporarily ceases to operate or manufacture whatever is being 
produced at that facility.
    Initial verification test means those leak tests that are conducted 
after the repair is finished to verify that a leak or leaks have been 
repaired before refrigerant is added back to the appliance.
    Leak inspection means the examination of an appliance to determine 
the location of refrigerant leaks. Potential methods include, but are 
not limited to, ultrasonic tests, gas-imaging cameras, bubble tests as 
appropriate, or the use of a leak detection device operated and 
maintained according to manufacturer guidelines. Methods that determine 
whether the appliance is leaking refrigerant but not the location of a 
leak, such as standing pressure/vacuum decay tests, sight glass checks, 
viewing receiver levels, pressure checks, and charging charts, must be 
used in conjunction with methods that can determine the location of a 
leak.
    Leak rate means the rate at which an appliance is losing 
refrigerant, measured between refrigerant charges. The leak rate is 
expressed in terms of the percentage of the appliance's full charge that 
would be lost over a 12-month period if the current rate of loss were to 
continue over that period. The rate must be calculated using one of the 
following methods. The same method must be used for all appliances 
subject to the leak repair requirements located at an operating 
facility.
    (1) Annualizing Method. (i) Step 1. Take the number of pounds of 
refrigerant added to the appliance to return it to a full charge, 
whether in one addition or if multiple additions related to same leak, 
and divide it by the number of pounds of refrigerant the appliance 
normally contains at full charge;
    (ii) Step 2. Take the shorter of the number of days that have passed 
since the last day refrigerant was added or 365 days and divide that 
number by 365 days;
    (iii) Step 3. Take the number calculated in Step 1 and divide it by 
the number calculated in Step 2; and
    (iv) Step 4. Multiply the number calculated in Step 3 by 100 to 
calculate a

[[Page 130]]

percentage. This method is summarized in the following formula:
[GRAPHIC] [TIFF OMITTED] TR18NO16.074

    (2) Rolling Average Method. (i) Step 1. Take the sum of the pounds 
of refrigerant added to the appliance over the previous 365-day period 
(or over the period that has passed since the last successful follow-up 
verification test showing all identified leaks in the appliance were 
repaired, if that period is less than one year);
    (ii) Step 2. Divide the result of Step 1 by the pounds of 
refrigerant the appliance normally contains at full charge; and
    (iii) Step 3. Multiply the result of Step 2 by 100 to obtain a 
percentage. This method is summarized in the following formula:

refrigerant and the disassembly or impairment of the refrigerant circuit 
such that the appliance as a whole is rendered unusable by any person in 
the future.
    Retrofit means to convert an appliance from one refrigerant to 
another refrigerant. Retrofitting includes the conversion of the 
appliance to achieve system compatibility with the new refrigerant and 
may include, but is not limited to, changes in lubricants, gaskets, 
filters, driers, valves, o-rings or appliance components.
    Seasonal variance means the removal of refrigerant from an appliance 
due to a change in ambient conditions caused by a change in season, 
followed by the subsequent addition of an amount that is less than or 
equal to the amount of refrigerant removed in the prior

[[Page 132]]

change in season, where both the removal and addition of refrigerant 
occurs within one consecutive 12-month period.
    Self-contained recovery equipment means refrigerant recovery and/or 
recycling equipment that is capable of removing the refrigerant from an 
appliance without the assistance of components contained in the 
appliance.

that is used as a refrigerant to replace a class I or II ozone-depleting 
substance. Examples include, but are not limited to hydrofluorocarbons, 
perfluorocarbons, hydrofluoroolefins, hydrofluoroethers, hydrocarbons, 
ammonia, carbon dioxide, and blends thereof. As used in this subpart, 
the term ``exempt substitutes'' refers to certain substitutes when used 
in certain end-uses that are specified in Sec.82.154(a)(1) as exempt 
from the venting prohibition and the requirements of this subpart, and 
the term ``non-exempt substitutes'' refers to all other substitutes and 
end-uses not so specified in Sec.82.154(a)(1).
    System-dependent recovery equipment means refrigerant recovery 
equipment that requires the assistance of components contained in an 
appliance to remove the refrigerant from the appliance.
    System receiver means the isolated portion of the appliance, or a 
specific vessel within the appliance, that is used to hold the 
refrigerant charge during the servicing or repair of that appliance.
    Technician means any person who in the course of maintenance, 
service, or repair of an appliance (except MVACs) could be reasonably 
expected to violate the integrity of the refrigerant circuit and 
therefore release refrigerants into the environment. Technician also 
means any person who in the course of disposal of an appliance (except 
small appliances, MVACs, and MVAC-like appliances) could be reasonably 
expected to violate the integrity of the refrigerant circuit and 
therefore release refrigerants from the appliances into the environment. 
Activities reasonably expected to violate the integrity of the 
refrigerant circuit include but are not limited to: Attaching or 
detaching hoses and gauges to and from the appliance; adding or removing 
refrigerant; adding or removing components; and cutting the refrigerant 
line. Activities such as painting the appliance, rewiring an external 
electrical circuit, replacing insulation on a length of pipe, or 
tightening nuts and bolts are not reasonably expected to violate the 
integrity of the refrigerant circuit. Activities conducted on appliances 
that have been properly evacuated pursuant to Sec.82.156 are not 
reasonably expected to release refrigerants unless the activity includes 
adding refrigerant to the appliance. Technicians could include but are 
not limited to installers, contractor employees, in-house service 
personnel, and owners and/or operators of appliances.
    Very high-pressure appliance means an appliance that uses a 
refrigerant with a critical temperature below 104 [deg]F or with a 
liquid phase saturation pressure above 355 psia at 104 [deg]F. Examples 
include but are not limited to appliances using R-13, R-23, R-503, R-
508A, and R-508B.

FR 61184, Dec. 27, 2017; 85 FR 14171, Apr. 10, 2020]



Sec.82.155  Safe disposal of appliances.

    Until January 1, 2018, this section applies only to disposal of 
appliances containing class I and class II refrigerants. Starting on 
January 1, 2018, this section applies to disposal of appliances 
containing any class I or class II refrigerant or any non-exempt 
substitute refrigerant.
    (a) Persons recovering refrigerant from a small appliance, MVAC, or 
MVAC-like appliance for purposes of disposal of these appliances must 
evacuate refrigerant to the levels in Sec.82.156(b) through (d) using 
recovery equipment that meets the standards in Sec.82.158(e) through 
(g), or 40 CFR part 82 subpart B, as applicable.
    (b) The final processor--i.e., persons who take the final step in 
the disposal process (including but not limited to scrap recyclers and 
landfill operators) of a small appliance, MVAC, or MVAC-like appliance--
must either:
    (1) Recover any remaining refrigerant from the appliance in 
accordance with paragraph (a) of this section; or
    (2) Verify using a signed statement or a contract that all 
refrigerant that had not leaked previously has been recovered from the 
appliance or shipment of appliances in accordance with paragraph (a) of 
this section. If using a signed statement, it must include the name and 
address of the person who recovered the refrigerant and the date the 
refrigerant was recovered. If using a signed contract between the 
supplier and the final processor, it must either state that the supplier 
will recover any remaining refrigerant from the appliance or shipment of 
appliances in accordance with paragraph (a) of this section prior to 
delivery or verify that the refrigerant had been properly recovered 
prior to receipt by the supplier.
    (i) It is a violation of this subpart to accept a signed statement 
or contract if the person receiving the statement or contract knew or 
had reason to know that the signed statement or contract is false.
    (ii) The final processor must notify suppliers of appliances that 
refrigerant must be properly recovered in accordance with paragraph (a) 
of this section before delivery of the items to the facility. The form 
of this notification may be signs, letters to suppliers, or other 
equivalent means.
    (iii) If all the refrigerant has leaked out of the appliance, the 
final processor must obtain a signed statement that all the refrigerant 
in the appliance had leaked out prior to delivery to the final processor 
and recovery is not possible. ``Leaked out'' in this context means those 
situations in which the refrigerant has escaped because of system 
failures, accidents, or other unavoidable occurrences not caused by a 
person's negligence or deliberate acts such as cutting refrigerant 
lines.
    (c) Recordkeeping. The final processor of a small appliance, MVAC, 
or MVAC-like appliance must keep a copy of all the signed statements or 
contracts obtained under paragraph (b)(2) of this section on site, in 
hard copy or in electronic format, for three years.

Sec.82.156  Proper evacuation of refrigerant from appliances.

    Until January 1, 2018, this section applies only to evacuation of 
refrigerant from appliances containing class I or class II refrigerants. 
Starting on January 1, 2018, this section applies to evacuation of 
refrigerant from appliances containing any class I or class II 
refrigerant or any non-exempt substitute refrigerant, excluding 
paragraph (i) of this section which applies only to appliances 
containing class I or class II refrigerants until January 1, 2019. 
Starting January 1, 2019, the provisions in Sec.82.157 apply in lieu 
of paragraph (i) of this section.
    (a) Appliances (except small appliances, MVACs, and MVAC-like 
appliances). Before opening appliances (except small appliances, MVACs, 
and MVAC-like appliances) or disposing of such appliances, technicians 
must evacuate the refrigerant, including all the liquid refrigerant, to 
the levels in Table 1 using a recovery and/or recycling machine 
certified pursuant to Sec.82.158 unless the situations in paragraphs 
(a)(1) or (2) of this section apply. Technicians may evacuate either the 
entire appliance or the part to be serviced, if the refrigerant in the 
part can be isolated to a system receiver. A technician must verify that 
the applicable level of evacuation has been reached in the appliance or 
the part before it is opened.
    (1) If evacuation of the appliance to the atmosphere is not to be 
performed after completion of the maintenance, service, or repair, and 
if the maintenance, service, or repair is not major as defined at Sec.
82.152, the appliance must:
    (i) Be evacuated to a pressure no higher than 0 psig before it is 
opened if it is a medium-, high- or very high-pressure appliance;
    (ii) Be pressurized to a pressure no higher than 0 psig before it is 
opened if it is a low-pressure appliance. Persons must cover openings 
when isolation is not possible. Persons pressurizing low-pressure 
appliances that use refrigerants with boiling points at or below 85 
degrees Fahrenheit at 29.9 inches of mercury (standard atmospheric 
pressure), must not use methods such as nitrogen that require subsequent 
purging. Persons pressurizing low-pressure appliances that use 
refrigerants with boiling points above 85 degrees Fahrenheit at 29.9 
inches of mercury, must use heat to raise the internal pressure of the 
appliance as much as possible, but may use nitrogen to raise the 
internal pressure of the appliance from the level attainable through use 
of heat to atmospheric pressure; or
    (iii) For the purposes of oil changes, be evacuated or pressurized 
to a pressure no higher than 5 psig, before it is opened; or drain the 
oil into a system receiver to be evacuated or pressurized to a pressure 
no higher than 5 psig.
    (2) If leaks in the appliance make evacuation to the levels in Table 
1 unattainable or would substantially contaminate the refrigerant being 
recovered, persons opening or disposing of the appliance must:
    (i) Isolate leaking from non-leaking components wherever possible;
    (ii) Evacuate non-leaking components to be opened or disposed of to 
the levels specified in Table 1; and
    (iii) Evacuate leaking components to be opened or disposed of to the 
lowest level that can be attained without substantially contaminating 
the refrigerant. This level may not exceed 0 psig.
    (3) Recordkeeping. As of January 1, 2018, technicians evacuating 
refrigerant from appliances with a full charge of more than 5 and less 
than 50 pounds of refrigerant for purposes of disposal of that appliance 
must keep records documenting the following for three years:
    (i) The company name, location of the appliance, date of recovery, 
and type of refrigerant recovered for each appliance;
    (ii) The total quantity of refrigerant, by type, recovered from all 
disposed appliances in each calendar month; and
    (iii) The quantity of refrigerant, by type, transferred for 
reclamation and/or destruction, the person to whom it was transferred, 
and the date of transfer.

    (b) Small appliances. Before opening a small appliance or when 
disposing of a small appliance, persons must recover refrigerant, using 
a recovery and/or recycling machine certified pursuant to Sec.82.158, 
according to the following conditions:
    (1) When using recovery equipment manufactured before November 15, 
1993, recover 80 percent of the refrigerant in the small appliance; or
    (2) When using recovery equipment manufactured on or after November 
15, 1993, recover 90 percent of the refrigerant in the appliance when 
the compressor in the appliance is functioning, or 80 percent of the 
refrigerant in the appliance when the compressor in the appliance is not 
functioning; or
    (3) Evacuate the appliance to four inches of mercury vacuum.
    (c) MVAC-like appliances. Persons may only open MVAC-like appliances 
while properly using, as defined at Sec.82.32(e), recovery and/or 
recycling equipment certified pursuant to Sec.82.158(f) or Sec.
82.36, as applicable. All persons recovering refrigerant from MVAC-like 
appliances for purposes of disposal of these appliances must evacuate 
the appliance in accordance with 40 CFR part 82, subpart B or reduce the 
system pressure to or below 102 mm of mercury vacuum.
    (d) MVACs. All persons recovering refrigerant from MVACs for 
purposes of disposal of these appliances must evacuate the appliance in 
accordance with 40 CFR part 82, subpart B or reduce the system pressure 
to or below 102 mm of mercury vacuum.
    (e) System-dependent equipment may not be used with appliances with 
a full charge of more than 15 pounds of refrigerant, unless the system-
dependent equipment is permanently attached to the appliance as a pump-
out unit.
    (f) Persons who maintain, service, repair, or dispose of only 
appliances that they own and that contain pump-out units are exempt from 
the requirement to use certified, self-contained recovery and/or 
recycling equipment.
    (g) All recovery and/or recycling equipment must be used in 
accordance with the manufacturer's directions unless such directions 
conflict with the requirements of this subpart.
    (h) Refrigerant may be returned to the appliance from which it is 
recovered or to another appliance owned by the same person without being 
recycled or reclaimed, unless the appliance is an MVAC or MVAC-like 
appliance.
    (i) The provisions in this paragraph (i) apply to owners and 
operators of appliances containing 50 or more pounds of class I and 
class II refrigerants only until January 1, 2019. The definitions in 
paragraph (j) of this section apply for purposes of this paragraph (i) 
in lieu of the definitions in Sec.82.152.
    (1) Owners or operators of commercial refrigeration equipment 
normally containing more than 50 pounds of refrigerant must have leaks 
repaired in

[[Page 138]]

accordance with paragraph (i)(9) of this section, if the appliance is 
leaking at a rate such that the loss of refrigerant will exceed 35 
percent of the total charge during a 12-month period, except as 
described in paragraphs (i)(6), (i)(8), and (i)(10) of this section and 
paragraphs (i)(1)(i), (i)(1)(ii), and (i)(1)(iii) of this section. 
Repairs must bring the annual leak rate to below 35 percent.
    (i) If the owners or operators of the federally-owned commercial 
refrigerant appliances determine that the leaks cannot be repaired in 
accordance with paragraph (i)(9) of this section and that an extension 
in accordance with the requirements discussed in this paragraph 
(i)(1)(i) of this section apply, they must document all repair efforts, 
and notify EPA of their inability to comply within the 30-day repair 
requirement, and the reason for the inability must be submitted to EPA 
in accordance with Sec.82.166(n). Such notification must be made 
within 30 days of discovering the leaks. EPA will determine if the 
extension requested in accordance with the requirements discussed in 
paragraph (i)(1)(i) of this section is justified. If the extension is 
not justified, EPA will notify the owner/operator within 30 days of 
receipt of the notification.
    (ii) Owners or operators of federally-owned commercial refrigeration 
equipment may have more than 30 days to repair leaks if the 
refrigeration appliance is located in an area subject to radiological 
contamination or where the shutting down of the appliance will directly 
lead to radiological contamination. Only the additional time needed to 
conduct and complete repairs in a safe working environment will be 
permitted.
    (iii) Owners or operators of federally-owned commercial 
refrigeration equipment requesting or who are granted time extensions 
under this paragraph must comply with paragraphs (i)(3) and (i)(4) of 
this section.
    (2) The owners or operators of industrial process refrigeration 
equipment normally containing more than 50 pounds of refrigerant must 
have leaks repaired if the appliance is leaking at a rate such that the 
loss of refrigerant will exceed 35 percent of the total charge during a 
12-month period in accordance with paragraph (i)(9) of this section, 
except as described in paragraphs (i)(6), (i)(7) and (i)(10) of this 
section, and paragraphs (i)(2)(i) and (i)(2)(ii) of this section. 
Repairs must bring annual leak rates to below 35 percent during a 12-
month period. If the owners or operators of the industrial process 
refrigeration equipment determine that the leak rate cannot be brought 
to below 35 percent during a 12-month period within 30 days (or 120 
days, where an industrial process shutdown in accordance with paragraph 
(i)(2)(ii) of this section is required,) and in accordance with 
paragraph (i)(9) of this section, and that an extension in accordance 
with the requirements discussed in this paragraph apply, the owners or 
operators of the appliance must document all repair efforts, and notify 
EPA of the reason for the inability in accordance with Sec.82.166(n) 
within 30 days of making this determination. Owners or operators who 
obtain an extension pursuant to this section or elect to utilize the 
additional time provided in paragraph (i)(2)(i) of this section, must 
conduct all necessary leak repairs, if any, that do not require any 
additional time beyond the initial 30 or 120 days.
    (i) The owners or operators of industrial process refrigeration 
equipment are permitted more than 30 days (or 120 days where an 
industrial process shutdown in accordance with paragraph (i)(2)(ii) of 
this section is required) to repair leaks, if the necessary parts are 
unavailable or if requirements of other applicable federal, state, or 
local regulations make a repair within 30 or 120 days impossible. Only 
the additional time needed to receive delivery of the necessary parts or 
to comply with the pertinent regulations will be permitted.
    (ii) Owners or operators of industrial process refrigeration 
equipment will have a 120-day repair period, rather than a 30-day repair 
period, to repair leaks in instances where an industrial process 
shutdown is needed to repair a leak or leaks from industrial process 
refrigeration equipment.
    (3) Owners or operators of industrial process refrigeration 
equipment and owners or operators of federally-owned

[[Page 139]]

commercial refrigeration equipment or of federally-owned comfort cooling 
appliances who are granted additional time under paragraphs (i)(1) or 
(i)(5) of this section, must have repairs performed in a manner that 
sound professional judgment indicates will bring the leak rate below the 
applicable allowable leak rate. When an industrial process shutdown has 
occurred or when repairs have been made while an appliance is 
mothballed, the owners or operators shall conduct an initial 
verification test at the conclusion of the repairs and a follow-up 
verification test. The follow-up verification test shall be conducted 
within 30 days of completing the repairs or within 30 days of bringing 
the appliance back on-line, if taken off-line, but no sooner than when 
the appliance has achieved normal operating characteristics and 
conditions. When repairs have been conducted without an industrial 
process shutdown or system mothballing, an initial verification test 
shall be conducted at the conclusion of the repairs, and a follow-up 
verification test shall be conducted within 30 days of the initial 
verification test. In all cases, the follow-up verification test shall 
be conducted at normal operating characteristics and conditions, unless 
sound professional judgment indicates that tests performed at normal 
operating characteristics and conditions will produce less reliable 
results, in which case the follow-up verification test shall be 
conducted at or near the normal operating pressure where practicable, 
and at or near the normal operating temperature where practicable.
    (i) If the owners or operators of industrial process refrigeration 
equipment takes the appliance off-line, or if the owners or operators of 
federally-owned commercial refrigeration or of federally-owned comfort 
cooling appliances who are granted additional time under paragraphs 
(i)(1) or (i)(5) of this section take the appliance off-line, they 
cannot bring the appliance back on-line until an initial verification 
test indicates that the repairs undertaken in accordance with paragraphs 
(i)(1)(i), (ii), (iii), or (i)(2)(i) and (ii), or (5)(i), (ii), and 
(iii) of this section have been successfully completed, demonstrating 
the leak or leaks are repaired. The owners or operators of the 
industrial process refrigeration equipment, federally-owned commercial 
refrigeration appliances, or federally-owned comfort cooling appliances 
are exempted from this requirement only where the owners or operators 
will retrofit or retire the industrial process refrigeration equipment, 
federally-owned commercial refrigeration appliance, or federally-owned 
comfort cooling appliance in accordance with paragraph (i)(6) of this 
section. Under this exemption, the owner or operators may bring the 
industrial process refrigeration equipment, federally-owned commercial 
refrigeration appliance, or federally-owned comfort cooling appliance 
back on-line without successful completion of an initial verification 
test.
    (ii) If the follow-up verification test indicates that the repairs 
to industrial process refrigeration equipment, federally-owned 
commercial refrigeration equipment, or federally-owned comfort cooling 
appliances have not been successful, the owner or operator must retrofit 
or retire the equipment in accordance with paragraph (i)(6) and any such 
longer time period as may apply under paragraphs (i)(7)(i), (ii) and 
(iii) or (i)(8)(i) and (ii) of this section. The owners and operators of 
the industrial process refrigeration equipment, federally-owned 
commercial refrigeration equipment, or federally-owned comfort cooling 
appliances are relieved of this requirement if the conditions of 
paragraphs (i)(3)(iv) and/or (i)(3)(v) of this section are met.
    (iii) The owner or operator of industrial process refrigeration 
equipment that fails a follow-up verification test must notify EPA 
within 30 days of the failed follow-up verification test in accordance 
with Sec.82.166(n).
    (iv) The owner or operator is relieved of the obligation to retrofit 
or replace the industrial process refrigeration equipment as discussed 
in paragraph (i)(6) of this section if second repair efforts to fix the 
same leaks that were the subject of the first repair efforts are 
successfully completed within 30 days or 120 days where an industrial 
process shutdown is required, after the initial failed follow-up 
verification

[[Page 140]]

test. The second repair efforts are subject to the same verification 
requirements of paragraphs (i)(3), (i)(3) (i) and (ii) of this section. 
The owner or operator is required to notify EPA within 30 days of the 
successful follow-up verification test in accordance with Sec.
82.166(n) and the owner or operator is no longer subject to the 
obligation to retrofit or replace the appliance that arose as a 
consequence of the initial failure to verify that the leak repair 
efforts were successful.
    (v) The owner or operator of industrial process refrigeration 
equipment is relieved of the obligation to retrofit or replace the 
equipment in accordance with paragraph (i)(6) of this section if within 
180 days of the initial failed follow-up verification test, the owner or 
operator establishes that the appliance's annual leak rate does not 
exceed the applicable allowable annual leak rate, in accordance with 
paragraph (i)(4) of this section. If the appliance's owner or operator 
establishes that the appliance's annual leak rate does not exceed the 
applicable allowable annual leak rate, the owner or operator is required 
to notify EPA within 30 days of that determination in accordance with 
Sec.82.166(n) and the owner or operator would no longer be subject to 
the obligation to retrofit or replace the equipment that arose as a 
consequence of the initial failure to verify that the leak repair 
efforts were successful.
    (4) In the case of a failed follow-up verification test subject to 
paragraph (i)(3)(v) of this section, the determination of whether 
industrial process refrigeration equipment has an annual leak rate that 
exceeds the applicable allowable annual leak rate will be made in 
accordance with parameters identified by the owner or operator in its 
notice to EPA regarding the failure of the initial follow-up 
verification test, if those parameters are acceptable to EPA; otherwise 
by parameters selected by EPA. The determination must be based on the 
full charge for the affected industrial process refrigeration equipment. 
The leak rate determination parameters in the owner's or operator's 
notice will be considered acceptable unless EPA notifies the owners or 
operators within 30 days of receipt of the notice. Where EPA does not 
accept the parameters identified by the owner or operator in its notice, 
EPA will not provide additional time beyond the additional time 
permitted in paragraph (i)(3)(v) of this section unless specifically 
stated in the parameters selected by EPA.
    (5) Owners or operators of comfort cooling appliances normally 
containing more than 50 pounds of refrigerant and not covered by 
paragraph (i)(1) or (i)(2) of this section must have leaks repaired in 
accordance with paragraph (i)(9) of this section if the appliance is 
leaking at a rate such that the loss of refrigerant will exceed 15 
percent of the total charge during a 12-month period, except as 
described in paragraphs (i)(6), (i)(8) and (i)(10) of this section and 
paragraphs (i)(5)(i), (i)(5)(ii) and (i)(5)(iii) of this section. 
Repairs must bring the annual leak rate to below 15 percent.
    (i) If the owners or operators of federally-owned comfort-cooling 
appliances determine that the leaks cannot be repaired in accordance 
with paragraph (i)(9) of this section and that an extension in 
accordance with the requirements discussed in paragraph (i)(5) of this 
section apply, they must document all repair efforts, and notify EPA of 
their inability to comply within the 30-day repair requirement, and the 
reason for the inability must be submitted to EPA in accordance with 
Sec.82.166(n). Such notification must be made within 30 days of 
discovering that leak repair efforts cannot be completed within 30 days.
    (ii) Owners or operators of federally-owned comfort-cooling 
appliances may have more than 30 days to repair leaks where the 
refrigeration appliance is located in an area subject to radiological 
contamination or where the shutting down of the appliance will directly 
lead to radiological contamination. Only the additional time needed to 
conduct and complete work in a safe environment will be permitted.
    (iii) Owners or operators of federally-owned comfort-cooling 
appliances requesting, or who are granted, time extensions under this 
paragraph must comply with paragraphs (i)(3) and (i)(4) of this section.
    (6) Owners or operators are not required to repair leaks as provided 
in

[[Page 141]]

paragraphs (i)(1), (i)(2), and (i)(5) of this section if, within 30 days 
of discovering a leak greater than the applicable allowable leak rate, 
or within 30 days of a failed follow-up verification test, or after 
making good faith efforts to repair the leaks as described in paragraph 
(i)(6)(i) of this section, they develop a one-year retrofit or 
retirement plan for the leaking appliance. Owners or operators who 
decide to retrofit the appliance must use a refrigerant or substitute 
with a lower or equivalent ozone-depleting potential than the previous 
refrigerant and must include such a change in the retrofit plan. Owners 
or operators who retire and replace the appliance must replace the 
appliance with an appliance that uses a refrigerant or substitute with a 
lower or equivalent ozone-depleting potential and must include such a 
change in the retirement plan. The retrofit or retirement plan (or a 
legible copy) must be kept at the site of the appliance. The original 
plan must be made available for EPA inspection upon request. The plan 
must be dated, and all work performed in accordance with the plan must 
be completed within one year of the plan's date, except as described in 
paragraphs (i)(6)(i), (i)(7), and (i)(8) of this section. Owners or 
operators are temporarily relieved of this obligation if the appliance 
has undergone system mothballing as defined in Sec.82.152.
    (i) If the owner or operator has made good faith efforts to repair 
leaks from the appliance in accordance with paragraphs (i)(1), (i)(2), 
or (i)(5) of this section and has decided prior to completing a follow-
up verification test, to retrofit or retire the appliance in accordance 
with paragraph (i)(6) of this section, the owner or operator must 
develop a retrofit or retirement plan within 30 days of the decision to 
retrofit or retire the appliance. The owner or operator must complete 
the retrofit or retirement of the appliance within one year and 30 days 
of when the owner or operator discovered that the leak rate exceeded the 
applicable allowable leak rate, except as provided in paragraphs (i)(7) 
and (i)(8) of this section.
    (ii) In all cases, subject to paragraph (i)(6)(i) of this section, 
the written plan shall be prepared no later than 30 days after the owner 
or operator has determined to proceed with retrofitting or retiring the 
appliance. All reports required under Sec.82.166(o) shall be due at 
the time specified in the paragraph imposing the specific reporting 
requirement, or no later than 30 days after the decision to retrofit or 
retire the appliance, whichever is later.
    (iii) In cases where the owner or operator of industrial process 
refrigeration equipment has made good faith efforts to retrofit or 
retire industrial process refrigeration equipment prior to August 8, 
1995, and where these efforts are not complete, the owner or operator 
must develop a retrofit or retirement plan that will complete the 
retrofit or retirement of the affected appliance by August 8, 1996. This 
plan (or a legible copy) must be kept at the site of the appliance. The 
original must be made available for EPA inspection upon request. Where 
the conditions of paragraphs (i)(7) and (i)(8) of this section apply, 
and where the length of time necessary to complete the work is beyond 
August 8, 1996, all records must be submitted to EPA in accordance with 
Sec.82.166(o), as well as maintained on-site.
    (7) The owners or operators of industrial process refrigeration 
equipment will be allowed additional time to complete the retrofit or 
retirement of industrial process refrigeration equipment if the 
conditions described in paragraphs (i)(7)(i) or (i)(7)(ii) of this 
section are met. The owners or operators of industrial process 
refrigeration equipment will be allowed additional time beyond the 
additional time provided in paragraph (i)(7)(ii) of this section if the 
conditions described in paragraph (i)(7)(iii) of this section are met.
    (i) Additional time, to the extent reasonably necessary will be 
allowed for retrofitting or retiring industrial process refrigeration 
equipment due to delays occasioned by the requirements of other 
applicable federal, state, or local laws or regulations, or due to the 
unavailability of a suitable replacement refrigerant with a lower ozone 
depletion potential. If these circumstances apply, the owner or operator 
of the facility must notify EPA within six months after the 30-day 
period following the discovery of an exceedance of the 35 percent leak 
rate.

[[Page 142]]

Records necessary to allow EPA to determine that these provisions apply 
and the length of time necessary to complete the work must be submitted 
to EPA in accordance with Sec.82.166(o), as well as maintained on-
site. EPA will notify the owner or operator of its determination within 
60 days of receipt the submittal.
    (ii) An additional one-year period beyond the initial one-year 
retrofit period is allowed for industrial process refrigeration 
equipment where the following criteria are met:
    (A) The new or the retrofitted industrial process refrigerant 
equipment is custom-built;
    (B) The supplier of the appliance or one or more of its critical 
components has quoted a delivery time of more than 30 weeks from when 
the order is placed;
    (C) The owner or operator notifies EPA within six months of the 
expiration of the 30-day period following the discovery of an exceedance 
of the 35 percent leak rate to identify the owner or operator, describe 
the appliance involved, explain why more than one year is needed, and 
demonstrate that the first two criteria are met in accordance with Sec.
82.166(o); and
    (D) The owner or operator maintains records that are adequate to 
allow a determination that the criteria are met.
    (iii) The owners or operators of industrial process refrigeration 
equipment may request additional time to complete retrofitting or 
retiring industrial process refrigeration equipment beyond the 
additional one-year period if needed and where the initial additional 
one year was granted in accordance with paragraph (i)(7)(ii) of this 
section. The request shall be submitted to EPA before the end of the 
ninth month of the first additional year and shall include revisions of 
information required under Sec.82.166(o). Unless EPA objects to this 
request submitted in accordance with Sec.82.166(o) within 30 days of 
receipt, it shall be deemed approved.
    (8) Owners or operators of federally-owned commercial or comfort-
cooling appliances will be allowed an additional year to complete the 
retrofit or retirement of the appliances if the conditions described in 
paragraph (i)(8)(i) of this section are met, and will be allowed one 
year beyond the additional year if the conditions in paragraph 
(i)(8)(ii) of this section are met.
    (i) Up to one additional one-year period beyond the initial one-year 
retrofit period is allowed for such equipment where the following 
criteria are met:
    (A) Due to complications presented by the federal agency 
appropriations and/or procurement process, a delivery time of more than 
30 weeks from the beginning of the official procurement process is 
quoted, or where the appliance is located in an area subject to 
radiological contamination and creating a safe working environment will 
require more than 30 weeks;
    (B) The operator notifies EPA within six months of the expiration of 
the 30-day period following the discovery of an exceedance of the 
applicable allowable annual leak rate to identify the operator, describe 
the appliance involved, explain why more than one year is needed, and 
demonstrate that the first criterion is met in accordance with Sec.
82.166(o); and
    (C) The operator maintains records adequate to allow a determination 
that the criteria are met.
    (ii) The owners or operators of federally-owned commercial or 
comfort-cooling appliances may request additional time to complete 
retrofitting, replacement or retiring such appliances beyond the 
additional one-year period if needed and where the initial additional 
one year was granted in accordance with paragraph (i)(8)(i) of this 
section. The request shall be submitted to EPA before the end of the 
ninth month of the first additional year and shall include revisions of 
information earlier submitted as required under Sec.82.166(o). Unless 
EPA objects to this request submitted in accordance with Sec.82.166(o) 
within 30 days of receipt, it shall be deemed approved.
    (9) Owners or operators must repair leaks pursuant to paragraphs 
(i)(1), (i)(2) and (i)(5) of this section within 30 days after 
discovery, or within 30 days after when the leaks should have been 
discovered if the owners intentionally shielded themselves from 
information

[[Page 143]]

which would have revealed a leak, unless granted additional time 
pursuant to Sec.82.156(i).
    (10) The amount of time for owners and operators to complete 
repairs, retrofit plans or retrofits/replacements/ retirements under 
paragraphs (i)(1), (i)(2), (i)(5), (i)(6), (i)(7), (i)(8), and (i)(9) of 
this section is temporarily suspended at the time an appliance is 
mothballed as defined in Sec.82.152. The time for owners and operators 
to complete repairs, retrofit plans, or retrofits/replacements will 
resume on the day the appliance is brought back on-line and is no longer 
considered mothballed. All initial and follow-up verification tests must 
be performed in accordance with paragraphs (i)(3), (i)(3)(i), and 
(i)(3)(ii) of this section.
    (11) In calculating annual leak rates, purged refrigerant that is 
destroyed at a verifiable destruction efficiency of 98 percent or 
greater will not be counted toward the leak rate. Owners or operators 
destroying purged refrigerants must maintain information as set forth in 
Sec.82.166(p)(1) and submit to EPA, within 60 days after the first 
time such exclusion is used by that facility, information set forth in 
Sec.82.166(p)(2).
    (j) Definitions for the leak repair provisions in 82.156(i). These 
definitions are not applicable to any other portion of subpart F other 
than 82.156(i). Along with paragraph (i) of this section, the 
definitions in this section apply only until January 1, 2019.
    Appliance means, for the purposes of paragraph (i) of this section, 
any device which contains and uses a refrigerant and which is used for 
household or commercial purposes, including any air conditioner, 
refrigerator, chiller, or freezer.
    Commercial refrigeration means, for the purposes of paragraph (i) of 
this section, the refrigeration appliances utilized in the retail food 
and cold storage warehouse sectors. Retail food includes the 
refrigeration equipment found in supermarkets, convenience stores, 
restaurants and other food service establishments. Cold storage includes 
the equipment used to store meat, produce, dairy products, and other 
perishable goods. All of the equipment contains large refrigerant 
charges, typically over 75 pounds.
    Critical component means, for the purposes of paragraph (i) of this 
section, a component without which industrial process refrigeration 
equipment will not function, will be unsafe in its intended environment, 
and/or will be subject to failures that would cause the industrial 
process served by the refrigeration appliance to be unsafe.
    Custom-built means, for the purposes of paragraph (i) of this 
section, that the equipment or any of its critical components cannot be 
purchased and/or installed without being uniquely designed, fabricated 
and/or assembled to satisfy a specific set of industrial process 
conditions.
    Follow-up verification test means, for the purposes of paragraph (i) 
of this section, those tests that involve checking the repairs within 30 
days of the appliance's returning to normal operating characteristics 
and conditions. Follow-up verification tests for appliances from which 
the refrigerant charge has been evacuated means a test conducted after 
the appliance or portion of the appliance has resumed operation at 
normal operating characteristics and conditions of temperature and 
pressure, except in cases where sound professional judgment dictates 
that these tests will be more meaningful if performed prior to the 
return to normal operating characteristics and conditions. A follow-up 
verification test with respect to repairs conducted without evacuation 
of the refrigerant charge means a reverification test conducted after 
the initial verification test and usually within 30 days of normal 
operating conditions. Where an appliance is not evacuated, it is only 
necessary to conclude any required changes in pressure, temperature or 
other conditions to return the appliance to normal operating 
characteristics and conditions.
    Full charge means, for the purposes of paragraph (i) of this 
section, the amount of refrigerant required for normal operating 
characteristics and conditions of the appliance as determined by using 
one or a combination of the following four methods:
    (i) Use the equipment manufacturer's determination of the correct 
full charge for the equipment;

[[Page 144]]

    (ii) Determine the full charge by making appropriate calculations 
based on component sizes, density of refrigerant, volume of piping, and 
other relevant considerations;
    (iii) Use actual measurements of the amount of refrigerant added or 
evacuated from the appliance; and/or
    (iv) Use an established range based on the best available data 
regarding the normal operating characteristics and conditions for the 
appliance, where the midpoint of the range will serve as the full 
charge, and where records are maintained in accordance with Sec.
82.166(q).
    Industrial process refrigeration means, for the purposes of 
paragraph (i) of this section, complex customized appliances used in the 
chemical, pharmaceutical, petrochemical and manufacturing industries. 
These appliances are directly linked to the industrial process. This 
sector also includes industrial ice machines, appliances used directly 
in the generation of electricity, and ice rinks. Where one appliance is 
used for both industrial process refrigeration and other applications, 
it will be considered industrial process refrigeration equipment if 50 
percent or more of its operating capacity is used for industrial process 
refrigeration.
    Industrial process shutdown means, for the purposes of paragraph (i) 
of this section, that an industrial process or facility temporarily 
ceases to operate or manufacture whatever is being produced at that 
facility.
    Initial verification test means, for the purposes of paragraph (i) 
of this section, those leak tests that are conducted as soon as 
practicable after the repair is completed. An initial verification test, 
with regard to the leak repairs that require the evacuation of the 
appliance or portion of the appliance, means a test conducted prior to 
the replacement of the full refrigerant charge and before the appliance 
or portion of the appliance has reached operation at normal operating 
characteristics and conditions of temperature and pressure. An initial 
verification test with regard to repairs conducted without the 
evacuation of the refrigerant charge means a test conducted as soon as 
practicable after the conclusion of the repair work.
    Leak rate means, for the purposes of paragraph (i) of this section, 
the rate at which an appliance is losing refrigerant, measured between 
refrigerant charges. The leak rate is expressed in terms of the 
percentage of the appliance's full charge that would be lost over a 12-
month period if the current rate of loss were to continue over that 
period. The rate is calculated using only one of the following methods 
for all appliances located at an operating facility.
    (i) Method 1. (A) Step 1. Take the number of pounds of refrigerant 
added to the appliance to return it to a full charge and divide it by 
the number of pounds of refrigerant the appliance normally contains at 
full charge;
    (B) Step 2. Take the shorter of the number of days that have passed 
since the last day refrigerant was added or 365 days and divide that 
number by 365 days;
    (C) Step 3. Take the number calculated in Step 1. and divide it by 
the number calculated in Step 2.; and
    (D) Step 4. Multiply the number calculated in Step 3. by 100 to 
calculate a percentage. This method is summarized in the following 
formula:
[GRAPHIC] [TIFF OMITTED] TR18NO16.076

    (ii) Method 2. (A) Step 1. Take the sum of the quantity of 
refrigerant added to the appliance over the previous 365-day period (or 
over the period that has passed since leaks in the appliance were last 
repaired, if that period is less than one year),

[[Page 145]]

    (B) Step 2. Divide the result of Step 1. by the quantity (e.g., 
pounds) of refrigerant the appliance normally contains at full charge, 
and
    (C) Step 3. Multiply the result of Step 2. by 100 to obtain a 
percentage. This method is summarized in the following formula:

    Normal operating characteristics or conditions means, for the 
purposes of paragraph (i) of this section, temperatures, pressures, 
fluid flows, speeds and other characteristics that would normally be 
expected for a given process load and ambient condition during 
operation. Normal operating characteristics and conditions are marked by 
the absence of atypical conditions affecting the operation of the 
refrigeration appliance.
    Normally containing a quantity of refrigerant means, for the 
purposes of paragraph (i) of this section, containing the quantity of 
refrigerant within the appliance or appliance component when the 
appliance is operating with a full charge of refrigerant.

any chemical or product, whether existing or new, that is used by any 
person as an EPA approved replacement for a class I or II ozone-
depleting substance in a given refrigeration or air-conditioning end-
use.
    Suitable replacement refrigerant means, for the purposes of 
paragraph (i) of this section, a refrigerant that is acceptable under 
section 612(c) of the Clean Air Act Amendments of 1990 and all 
regulations promulgated under that section, compatible with other 
materials with which it may come into contact, and able to achieve the 
temperatures required for the affected industrial process in a 
technically feasible manner.
    System mothballing means, for the purposes of paragraph (i) of this 
section, the intentional shutting down of a refrigeration appliance 
undertaken for an extended period of time by the owners or operators of 
that facility, where the refrigerant has been evacuated from the

Sec.82.157  Appliance maintenance and leak repair.

    (a) Applicability. This section applies as of January 1, 2019. As of 
April 10, 2020, this section applies only to appliances with a full 
charge of 50 or more pounds of any class I or class II refrigerant or 
blend containing a class I or class II refrigerant. Notwithstanding the 
use of the term refrigerant in this section, the requirements of this 
section do not apply to appliances containing solely substitute 
refrigerants. Unless otherwise specified, the requirements of this 
section apply to the owner or operator of the appliance.
    (b) Leak Rate Calculation. Persons adding or removing refrigerant 
from an appliance must, upon conclusion of that service, provide the 
owner or operator with documentation that meets the applicable 
requirements of paragraph (l)(2) of this section. The owner or operator 
must calculate the leak rate every time refrigerant is added to an 
appliance unless the addition is made immediately following a retrofit,

[[Page 146]]

installation of a new appliance, or qualifies as a seasonal variance.
    (c) Requirement to Address Leaks through Appliance Repair, or 
Retrofitting or Retiring an Appliance. (1) Owners or operators must 
repair appliances with a leak rate over the applicable leak rate in this 
paragraph in accordance with paragraphs (d) through (f) of this section 
unless the owner or operator elects to retrofit or retire the appliance 
in compliance with paragraphs (h) and (i) of this section. If the owner 
or operator elects to repair leaks, but fails to bring the leak rate 
below the applicable leak rate, the owner or operator must create and 
implement a retrofit or retirement plan in accordance with paragraphs 
(h) and (i) of this section.
    (2) Leak Rates:
    (i) 20 percent leak rate for commercial refrigeration equipment;
    (ii) 30 percent leak rate for industrial process refrigeration 
equipment; and
    (iii) 10 percent leak rate for comfort cooling appliances or other 
appliances with a full charge of 50 or more pounds of refrigerant not 
covered by (c)(2)(i) or (ii) of this section.
    (d) Appliance Repair. Owners or operators must identify and repair 
leaks in accordance with this paragraph within 30 days (or 120 days if 
an industrial process shutdown is required) of when refrigerant is added 
to an appliance exceeding the applicable leak rate in paragraph (c) of 
this section.
    (1) A certified technician must conduct a leak inspection, as 
described in paragraph (g) of this section, to identify the location of 
leaks.
    (2) Leaks must be repaired such that the leak rate is brought below 
the applicable leak rate. This must be confirmed by the leak rate 
calculation performed upon the next refrigerant addition. The leaks will 
be presumed to be repaired if there is no further refrigerant addition 
for 12 months after the repair or if the leak inspections required under 
paragraph (g) do not find any leaks in the appliance. Repair of leaks 
must be documented by both an initial and a follow-up verification test 
or tests.
    (3) The time frames in paragraphs (d) through(f) of this section are 
temporarily suspended when an appliance is mothballed. The time will 
resume on the day additional refrigerant is added to the appliance (or 
component of an appliance if the leaking component was isolated).
    (e) Verification tests. The owner or operator must conduct both 
initial and follow-up verification tests on each leak that was repaired 
under paragraph (d) of this section.
    (1) Initial verification test. Unless granted additional time, an 
initial verification test must be performed within 30 days (or 120 days 
if an industrial process shutdown is required) of an appliance exceeding 
the applicable leak rate in paragraph (c) of this section. An initial 
verification test must demonstrate that leaks where a repair attempt was 
made are repaired.
    (i) For repairs that can be completed without the need to open or 
evacuate the appliance, the test must be performed after the conclusion 
of the repair work and before any additional refrigerant is added to the 
appliance.
    (ii) For repairs that require the evacuation of the appliance or 
portion of the appliance, the test must be performed before adding any 
refrigerant to the appliance.
    (iii) If the initial verification test indicates that the repairs 
have not been successful, the owner or operator may conduct as many 
additional repairs and initial verification tests as needed within the 
applicable time period.
    (2) Follow-up verification test. A follow-up verification test must 
be performed within 10 days of the successful initial verification test 
or 10 days of the appliance reaching normal operating characteristics 
and conditions (if the appliance or isolated component was evacuated for 
the repair(s)). Where it is unsafe to be present or otherwise impossible 
to conduct a follow-up verification test when the system is operating at 
normal operating characteristics and conditions, the verification test 
must, where practicable, be conducted prior to the system returning to 
normal operating characteristics and conditions.
    (i) A follow-up verification test must demonstrate that leaks where 
a repair attempt was made are repaired. If the follow-up verification 
test indicates

[[Page 147]]

that the repairs have not been successful, the owner or operator may 
conduct as many additional repairs and verification tests as needed to 
bring the appliance below the leak rate within the applicable time 
period and to verify the repairs.
    (f) Extensions to the appliance repair deadlines. Owners or 
operators are permitted more than 30 days (or 120 days if an industrial 
process shutdown is required) to comply with paragraphs (d) and (e) of 
this section if they meet the requirements of (f)(1) through (4) of this 
section or the appliance is mothballed. The request will be considered 
approved unless EPA notifies the owners or operators otherwise.
    (1) One or more of the following conditions must apply:
    (i) The appliance is located in an area subject to radiological 
contamination or shutting down the appliance will directly lead to 
radiological contamination. Additional time is permitted to the extent 
needed to conduct and finish repairs in a safe working environment.
    (ii) Requirements of other applicable Federal, state, or local 
regulations make a repair within 30 days (or 120 days if an industrial 
process shutdown is required) impossible. Additional time is permitted 
to the extent needed to comply with the pertinent regulations.
    (iii) Components that must be replaced as part of the repair are not 
available within 30 days (or 120 days if an industrial process shutdown 
is required). Additional time is permitted up to 30 days after receiving 
delivery of the necessary components, not to exceed 180 days (or 270 
days if an industrial process shutdown is required) from the date the 
appliance exceeded the applicable leak rate.
    (2) Repairs to leaks that the technician has identified as 
significantly contributing to the exceedance of the leak rate and that 
do not require additional time must be completed and verified within the 
initial 30 day repair period (or 120 day repair period if an industrial 
process shutdown is required);
    (3) The owner or operator must document all repair efforts and the 
reason for the inability to make the repair within the initial 30 day 
repair period (or 120 day repair period if an industrial process 
shutdown is required); and
    (4) The owner or operator must request an extension from EPA at the 
address specified in paragraph (m) of this section within 30 days (or 
120 days if an industrial process shutdown is required) of the appliance 
exceeding the applicable leak rate in paragraph (c) of this section. 
Extension requests must include: Identification and address of the 
facility; the name of the owner or operator of the appliance; the leak 
rate; the method used to determine the leak rate and full charge; the 
date the appliance exceeded the applicable leak rate; the location of 
leak(s) to the extent determined to date; any repair work that has been 
performed thus far, including the date that work was completed; the 
reasons why more than 30 days (or 120 days if an industrial process 
shutdown is required) are needed to complete the repair; and an estimate 
of when the work will be completed. If the estimated completion date is 
to be extended, a new estimated date of completion and documentation of 
the reason for that change must be submitted to EPA within 30 days of 
identifying that the completion date must be extended. The owner or 
operator must keep a dated copy of this submission.
    (g) Leak Inspections. (1) The owner or operator must conduct a leak 
inspection in accordance with the following schedule on any appliance 
exceeding the applicable leak rate in paragraph (c)(2) of this section.
    (i) For commercial refrigeration and industrial process 
refrigeration appliances with a full charge of 500 or more pounds, leak 
inspections must be conducted once every three months until the owner or 
operator can demonstrate through the leak rate calculations required 
under paragraph (b) of this section that the appliance has not leaked in 
excess of the applicable leak rate for four quarters in a row.
    (ii) For commercial refrigeration and industrial process 
refrigeration appliances with a full charge of 50 or more pounds but 
less than 500 pounds, leak inspections must be conducted once per 
calendar year until the owner or operator can demonstrate through the 
leak

[[Page 148]]

rate calculations required under paragraph (b) of this section that the 
appliance has not leaked in excess of the applicable leak rate for one 
year.
    (iii) For comfort cooling appliances and other appliances not 
covered by paragraphs (g)(1)(i) and (ii) of this section, leak 
inspections must be conducted once per calendar year until the owner or 
operator can demonstrate through the leak rate calculations required 
under paragraph (b) of this section that the appliance has not leaked in 
excess of the applicable leak rate for one year.
    (2) Leak inspections must be conducted by a certified technician 
using method(s) determined by the technician to be appropriate for that 
appliance.
    (3) All visible and accessible components of an appliance must be 
inspected, with the following exceptions:
    (i) Where components are insulated, under ice that forms on the 
outside of equipment, underground, behind walls, or are otherwise 
inaccessible;
    (ii) Where personnel must be elevated more than two meters above a 
support surface; or
    (iii) Where components are unsafe to inspect, as determined by site 
personnel.
    (4) Quarterly or annual leak inspections are not required on 
appliances, or portions of appliances, continuously monitored by an 
automatic leak detection system that is audited or calibrated annually. 
An automatic leak detection system may directly detect refrigerant in 
air, monitor its surrounding in a manner other than detecting 
refrigerant concentrations in air, or monitor conditions of the 
appliance.
    (i) For systems that directly detect the presence of a refrigerant 
in air, the system must:
    (A) Only be used to monitor components located inside an enclosed 
building or structure;
    (B) Have sensors or intakes placed so that they will continuously 
monitor the refrigerant concentrations in air in proximity to the 
compressor, evaporator, condenser, and other areas with a high potential 
for a refrigerant leak;
    (C) Accurately detect a concentration level of 10 parts per million 
of vapor of the specific refrigerant or refrigerants used in the 
refrigeration appliance(s); and
    (D) Alert the owner or operator when a refrigerant concentration of 
100 parts per million of vapor of the specific refrigerant or 
refrigerants used in the refrigeration appliance(s) is reached.
    (ii) For a system that monitors its surrounding in a manner other 
than detecting refrigerant concentrations in air or monitor conditions 
of the appliance, the system must automatically alert the owner or 
operator when measurements indicate a loss of 50 pounds of refrigerant 
or 10 percent of the full charge, whichever is less.
    (iii) When automatic leak detection equipment is only being used to 
monitor portions of an appliance, the remainder of the appliance 
continues to be subject to any applicable leak inspection requirements.
    (h) Retrofit or retirement plans. (1) The owner or operator must 
create a retrofit or retirement plan within 30 days of:
    (i) an appliance leaking above the applicable leak rate in paragraph 
(c) of this section if the owner or operator intends to retrofit or 
retire rather than repair the leak;
    (ii) an appliance leaking above the applicable leak rate in 
paragraph (c) of this section if the owner or operator fails to take any 
action to identify or repair the leak; or
    (iii) an appliance continues to leak above the applicable leak rate 
after having conducted the required repairs and verification tests under 
paragraphs (d) and (e) of this section.
    (2) A retrofit or retirement plan must, at a minimum, contain the 
following information:
    (i) Identification and location of the appliance;
    (ii) Type and full charge of the refrigerant used in the appliance;
    (iii) Type and full charge of the refrigerant to which the appliance 
will be converted, if retrofitted;
    (iv) Itemized procedure for converting the appliance to a different 
refrigerant, including changes required for compatibility with the new 
substitute, if retrofitted;
    (v) Plan for the disposition of recovered refrigerant;

[[Page 149]]

    (vi) Plan for the disposition of the appliance, if retired; and
    (vii) A schedule, not to exceed one-year, for completion of the 
appliance retrofit or retirement.
    (3) The retrofit or retirement plan must be signed by an authorized 
company official, dated, accessible at the site of the appliance in 
paper copy or electronic format, and available for EPA inspection upon 
request.
    (4) All identified leaks must be repaired as part of any retrofit 
under such a plan.
    (5)(i) Unless granted additional time, all work performed in 
accordance with the plan must be finished within one year of the plan's 
date (not to exceed 13 months from when the plan was required in 
paragraph (h)(1) of this section).
    (ii) The owner or operator may request that EPA relieve it of the 
obligation to retrofit or retire an appliance if the owner or operator 
can establish within 180 days of the plan's date that the appliance no 
longer exceeds the applicable leak rate and if the owner or operator 
agrees in writing to repair all identified leaks within one year of the 
plan's date consistent with paragraph (h)(4) and (h)(5)(i) of this 
section. The owner or operator must submit to EPA the retrofit or 
retirement plan as well as the following information: The date that the 
requirement to develop a retrofit or retirement plan was triggered; the 
leak rate; the method used to determine the leak rate and full charge; 
the location of the leak(s) identified in the leak inspection; a 
description of repair work that has been completed; a description of 
repair work that has not been completed; a description of why the repair 
was not conducted within the time frames required under paragraphs (d) 
and (f) of this section; and a statement signed by an authorized 
official that all identified leaks will be repaired and an estimate of 
when those repairs will be completed (not to exceed one year from date 
of the plan). The request will be considered approved unless EPA 
notifies the owners or operators within 60 days of receipt of the 
request that it is not approved.
    (i) Extensions to the one-year retrofit or retirement schedule. 
Owners or operators may request more than one year to comply with 
paragraph (h) of this section if they meet the requirements of this 
paragraph. The request will be considered approved unless EPA notifies 
the owners or operators within 60 days of receipt of the request that it 
is not approved. The request must be submitted to EPA at the address 
specified in Sec.82.157(m) within seven months of discovering the 
appliance exceeded the applicable leak rate. The request must include 
the identification of the appliance; name of the owner or operator; the 
leak rate; the method used to determine the leak rate and full charge; 
the date the appliance exceeded the applicable leak rate; the location 
of leaks(s) to the extent determined to date; any repair work that has 
been finished thus far, including the date that work was finished; a 
plan to finish the retrofit or retirement of the appliance; the reasons 
why more than one year is necessary to retrofit or retire the appliance; 
the date of notification to EPA; and an estimate of when retrofit or 
retirement work will be finished. A dated copy of the request must be 
available on-site in either electronic or paper copy. If the estimated 
completion date is to be revised, a new estimated date of completion and 
documentation of the reason for that change must be submitted to EPA at 
the address specified in Sec.82.157(m) within 30 days. Additionally, 
the time frames in paragraphs (h) and (i) of this section are 
temporarily suspended when an appliance is mothballed. The time will 
resume running on the day additional refrigerant is added to the 
appliance (or component of an appliance if the leaking component was 
isolated).
    (1) Extensions available to any appliance. Owners or operators of 
commercial refrigeration, industrial process refrigeration, comfort-
cooling, or other equipment are automatically allowed 18 months to 
retire an appliance if the replacement appliance uses a substitute 
refrigerant exempted under Sec.82.154(a).

installed within 120 days after receiving delivery of the necessary 
parts; or
    (iii) After receiving an extension under paragraph (i)(2)(ii) of 
this section, owners or operators may request additional time if 
necessary to finish the retrofit or retirement of equipment. The request 
must be submitted to EPA before the end of the ninth month of the 
initial extension and must include the same information submitted for 
that extension, with any necessary revisions. A dated copy of the 
request must be available on-site in either electronic or paper copy. 
The request will be considered approved unless EPA notifies the owners 
or operators within 60 days of receipt of the request that it is not 
approved.
    (3) Extensions available to Federally owned equipment. Owners or 
operators of federally owned commercial or comfort-cooling equipment may 
request an additional year beyond the one-year period in paragraph (h) 
of this section to finish the retrofit or retirement under the following 
circumstances:
    (i) A delivery time of more than 30 weeks from the beginning of the 
official procurement process is quoted due to complications presented by 
the Federal agency appropriations and/or procurement process;
    (ii) The appliance is located in an area subject to radiological 
contamination and creating a safe working environment will require more

planned but not yet completed to achieve a rate below the applicable 
allowable leak rate. A plan to fix other outstanding leaks in accordance 
with Sec.82.156(i)(3)(v) must include the following information: The 
identification of the facility; the leak rate; the method used to 
determine the leak rate and full charge; the date a leak rate above the 
applicable allowable leak rate was discovered; the location of leak(s) 
to the extent determined to date; and any repair work that has been 
completed thus far, including the date that work was completed. Upon 
completion of the repair efforts described in the plan, a second report 
must be submitted that includes the date the owner or operator submitted 
the initial report concerning the need for additional time beyond the 30 
days and notification of the owner or operator's determination that the 
leak rate no longer exceeds the applicable allowable leak rate. This 
second report must be submitted within 30 days of determining that the 
leak rate no longer exceeds the applicable allowable leak rate.
    (3) Owners or operators must maintain records of the dates, types,

    4.3.3 Water
    4.3.4 High boiling residue
    4.3.5 Particulates/solids

           Section 5. Sampling and Summary of Test Procedures

    5.1 Referee Test. The referee test methods for the various 
contaminants are summarized in the following paragraphs. Detailed test 
procedures are included in 2008 Appendix C to AHRI Standard 700-2014 
(incorporated by reference, see Sec.82.168). If alternative test 
methods are employed, the user must be able to demonstrate that they 
produce results at least equivalent to the specified referee test 
method.
    5.2 Refrigerant Sampling
    5.2.1 Sampling Precautions. Special precautions should be taken to 
ensure that representative samples are obtained for analysis. Sampling 
shall be done by qualified personnel following accepted sampling and 
safety procedures. Refrigerants with critical temperatures near or below 
ambient temperature cannot be reliably sampled for both liquid and vapor 
phase without special handling.
    Note: Flammable refrigerants which are ASHRAE 34 class 2L, 2, or 3 
present additional safety challenges and require additional measures for 
sampling safety procedures compared to nonflammable halocarbons 
documented in this standard.
    5.2.2 Cylinder Preparation. Place a clean, empty sample cylinder 
with the valve open in an oven at 110 [deg]C (230 [deg]F) for one hour. 
Remove it from the oven while hot, immediately connect it to an 
evacuation system and evacuate to less than 56 kPa. Close the valve and 
allow it to cool. Weigh the empty cylinder.
    5.2.3 Vapor Phase Sampling. A vapor phase sample shall be obtained 
for determining the non-condensables. The source temperature shall be 
measured and recorded at the time the sample is taken.
    5.2.3.1 Special Handling for Low Critical Temperature Refrigerant. A 
vapor phase sample is required to determine non-condensables and 
volatile impurities, including other refrigerants. The vapor phase 
sample is obtained by regulating the sample container temperature to 5 K 
or more above the refrigerant critical temperature.
    5.2.3.2 Handling for Liquid Refrigerants with Boiling Points Near or 
Above Room Temperature. Since R-11, R-113, R-123, R-141b, R-245fa, and 
R-1233zd(E) have normal boiling points near or above room temperature, 
non-condensable determination is not required for these refrigerants.
    Note: Non-condensable gases, if present, will concentrate in the 
vapor phase of the refrigerant; care must be exercised to eliminate 
introduction of either air or liquid phase refrigerant during the sample 
transfer.
    5.2.4 Liquid Phase Sampling. A liquid phase sample is required for 
all tests listed in this standard except the test for non-condensables.
    5.2.4.1 Liquid Sampling. Accurate analysis requires that the sample 
cylinder, at ambient temperature, be filled to at least 60 percent by 
volume; however, under no circumstances should the cylinder be filled to 
more than 80 percent by volume. This can be accomplished by weighing the 
empty cylinder and then the cylinder with refrigerant. When the desired 
amount of refrigerant has been collected, close the valve(s) and 
immediately disconnect the sample cylinder.
    Note: Care should be taken to ensure that all connections and 
transfer lines are dry and evacuated to avoid contaminating the sample.
    Note: Low critical temperature refrigerants can have extremely high 
pressure and the sampling vessel, all connections, and transfer lines 
must be designed to handle high pressures.
    5.2.4.2 Special Handling for Low Critical Temperature Refrigerant. A 
liquid phase sample is required for all testing except volatile 
impurities, including other refrigerants. The liquid phase sample is 
obtained by regulating the sample cylinder temperature to 2 [deg]C below 
the critical temperature of the refrigerant.
    Note: If free water is present in the sample, cooling to below 0 
[deg]C may result in the formation of ice. Clathrates may form at 
temperatures above 0 [deg]C with some fluorocarbon refrigerants.
    5.2.4.3 Record Weight. Check the sample cylinder for leaks and 
record the gross weight.
    5.3 Refrigerant Identification. The required method shall be gas 
chromatography (GC) as described in 2008 Appendix C to AHRI Standard 
700-2014 (incorporated by reference, see Sec.82.168) with the 
corresponding gas chromatogram figures as illustrated in 2012 Appendix D 
to AHRI Standard 700-2014 (incorporated by reference, see Sec.82.168). 
The chromatogram of the sample shall be compared to known standards.
    5.3.2 Alternative Method. Determination of the boiling point and 
boiling point range is

[[Page 165]]

an acceptable alternative test method which can be used to characterize 
refrigerants. The test method shall be that described in section 4.4.3 
of BB-F-1421B (incorporated by reference, see Sec.82.168).
    5.3.3 Required Values. The required values for boiling point and 
boiling point range are given in Table 1A, Physical Properties of Single 
Component Refrigerants; Table 1B, Physical Properties of Zeotropic 
Blends (400 Series Refrigerants); and Table 1C, Physical Properties of 
Azeotropic Blends (500 Series Refrigerants).
    5.4 Water Content.
    5.4.1 Method. The Coulometric Karl Fischer Titration shall be the 
primary test method for determining the water content of refrigerants. 
This method is described in 2008 Appendix C to AHRI Standard 700-2014 
(incorporated by reference, see Sec.82.168). This method can be used 
for refrigerants that are either a liquid or a gas at room temperature. 
For all refrigerants, the sample for water analysis shall be taken from 
the liquid phase of the container to be tested.
    5.4.2 Limits. The value for water content shall be expressed in 
parts per million (ppm) by weight and shall not exceed the maximum 
specified in Tables 1A, 1B, 1C, 2A, 2B, and 3.
    5.5 Conductivity. (Alternative to chloride and acidity tests).
    5.5.1 Method. A refrigerant may be tested for conductivity as an 
indication of the presence of acids, metal chlorides, and any compound 
that ionizes in water. This alternative procedure is intended for use 
with new or reclaimed refrigerants, however, significant amounts of oil 
can interfere with the test results.
    5.5.2 Limits. The value for conductivity shall be converted to and 
expressed in ppm by weight calculated as HCl and shall be compared with 
the maximum acidity value specified (see in Tables 1A, 1B, 1C, 2A, 2B, 
and 3). If the conductivity is above this amount, then the chloride and 
acidity tests shall be conducted. If the conductivity is not greater 
than this amount, then the chloride and acidity tests may be omitted.
    5.6 Chloride. The refrigerant shall be tested for chloride as an 
indication of the presence of hydrochloric acid and/or metal chlorides. 
The referee procedure is intended for use with new or reclaimed 
halogenated refrigerants; however, high boiling residue in excess of the 
amounts in Tables 1A, 1B, 1C, 2A, 2B, and 3 can interfere with the test 
results.
    5.6.1 Method. The test method shall be that described in 2008 
Appendix C to AHRI Standard 700-2014 (incorporated by reference, see 
Sec.82.168). The test will show noticeable turbidity at chloride 
levels of about 3 ppm or greater by weight.
    5.5.2 Limits. The results of the test shall not exhibit any sign of 
turbidity. Report the results as ``pass'' or ``fail.''
    5.7 Acidity.
    5.7.1 Method. The acidity test uses the titration principle to 
detect any compound that is soluble in water and ionizes as an acid. The 
test method shall be that described in 2008 Appendix C to AHRI Standard 
700-2014 (incorporated by reference, see Sec.82.168). This test may 
not be suitable for determination of high molecular weight organic 
acids; however these acids will be found in the high boiling residue 
test outlined in Section 5.8. The test requires a 50 to 60 gram sample 
and has a detection limit of 0.1 ppm by weight calculated as HCl.
    5.7.2 Limits. The value for acidity shall be expressed in ppm by 
weight as HCl and shall not exceed the limits in Tables 1A, 1B, 2A, 2B, 
and 3.
    5.8 High Boiling Residue.
    5.8.1 Method. High boiling residue shall be determined by either 
volume or weight. The volume method measures the residue from a standard 
volume of refrigerant after evaporation. The gravimetric method is 
described in 2008 Appendix C to AHRI Standard 700-2014 (incorporated by 
reference, see Sec.82.168). Oils and/or organic acids will be captured 
by these methods.
    5.8.2 Limits. The value for high boiling residue shall be expressed 
as a percentage by volume or weight and shall not exceed the maximum 
percent specified in Tables 1A, 1B, 1C, 2A, 2B, and 3.
    5.9 Particulates and Solids.
    5.9.1 Method. A measured amount of sample shall be placed in a Goetz 
bulb under controlled temperature conditions. The particulates/solids 
shall be determined by visual examination of the Goetz bulb prior to the 
evaporation of refrigerant. For details of this test method, refer to 
Part 3 of 2008 Appendix C to AHRI Standard 700-2014 (incorporated by 
reference, see Sec.82.168).
    Note: R-744 will partially sublimate when measuring a known amount 
of liquid sample into the dry Goetz bulb and the solid R-744 will 
interfere with the visual examination of particulates/solids. 
Determining the particulates/solids shall be completed by visual 
examination of the Goetz bulb after the evaporation of the refrigerant.
    5.9.2 Limits. Visual presence of dirt, rust, or other particulate 
contamination is reported as ``fail.''
    5.10 Non-Condensables.
    5.10.1 Method. A vapor phase sample shall be used for determination 
of non-condensables. Non-condensable gases consist primarily of air 
accumulated in the vapor phase of refrigerants where the solubility of 
air in the refrigerant liquid phase is extremely low and air is not 
significant as a liquid phase contaminant. The presence of non-
condensable gases may reflect poor quality control in transferring 
refrigerants to storage tanks and cylinders.

[[Page 166]]

    The test method shall be gas chromatography with a thermal 
conductivity detector as described in 2008 Appendix C to AHRI Standard 
700-2014 (incorporated by reference, see Sec.82.168).
    5.10.2 Limits. The maximum level of non-condensables in the vapor 
phase of a test sample shall not exceed the maximum at 25 [deg]C as 
shown in Tables 1A, 1B, 1C, 2A, 2B, and 3.
    5.11 All Other Volatile Impurities and/or Other Refrigerants.
    5.11.1 Method. The amount of volatile impurities including other 
refrigerants in the subject refrigerant shall be determined by gas 
chromatography as described in 2008 Appendix C to AHRI Standard 700-2014 
(incorporated by reference, see Sec.82.168).
    5.11.2 Limits. The test sample shall not contain more than 0.5 
percent by weight of volatile impurities including other refrigerants as 
shown in Tables 1A, 1B, 1C, 2A, 2B and 3.
    5.12 Total C3, C4 and C5 Polyolefins in Hydrocarbon Refrigerants.
    5.12.1 Method. The amount of polyolefin impurities in the 
hydrocarbon shall be determined by gas chromatography as described in 
GPA Standard 2177-13 (incorporated by reference, see Sec.82.168).
    5.12.2 Limits. The test sample shall not contain more than 0.05 
percent by weight in the hydrocarbon sample as shown in Tables 1B and 
2B. Report the results as ``pass'' or ``fail.''
    5.13 Sulfur Odor in Hydrocarbon Refrigerants.
    5.13.1 Method. The amount of sulfur containing compounds or other 
compounds with an odor shall be determined by ASTM D1296-01 (Reapproved 
2012) (incorporated by reference, see Sec.82.168).
    5.13.2 Limits. The test sample paper shall not emit a residual 
sulfur odor as shown in Tables 1B and 2B.

                     Section 6. Reporting Procedure

    6.1 Reporting Procedure. The source (manufacturer, reclaimer, or 
repackager) of the packaged refrigerant shall be identified. The 
refrigerant shall be identified by its accepted refrigerant number and/
or its chemical name. Maximum allowable levels of contaminants are shown 
in Tables 1A, 1B, 1C, 2A, 2B, and 3. Test results shall be tabulated in 
a similar manner.

  Sec. Appendix B1 to Subpart F of Part 82--Performance of Refrigerant 
              Recovery, Recycling and/or Reclaim Equipment

    This appendix is based on the Air-Conditioning and Refrigeration 
Institute Standard 740-1993.

                Refrigerant Recovery/Recycling Equipment

                           Section 1. Purpose

    1.1 Purpose. The purpose of this standard is to establish methods of 
testing for rating and evaluating the performance of refrigerant 
recovery, and/or recycling equipment, and general equipment requirements 
(herein referred to as ``equipment'') for containment or purity levels, 
capacity, speed, and purge loss to minimize emission into the atmosphere 
of designated refrigerants.
    1.1.1 This standard is intended for the guidance of the industry, 
including manufacturers, refrigerant reclaimers, repackers, 
distributors, installers, servicemen, contractors and for consumers.
    1.1.2 This standard is not intended to be used as a guide in 
defining maximum levels of contaminants in recycled or reclaimed 
refrigerants used in various applications.
    1.2 Review and Amendment. This standard is subject to review and 
amendment as the technology advances.

                            Section 2. Scope

    2.1 Scope. This standard defines general equipment requirements and 
the test apparatus, test mixtures, sampling and analysis techniques that 
will be used to determine the performance of recovery and/or recycling 
equipment for various refrigerants including R11, R12, R13, R22, R113, 
R114, R123, R134a, R500, R502, and R503, as referenced in the ANSI/
ASHRAE Standard 34-1992, ``Number Designation of Refrigerants'' 
(American Society of Heating, Refrigerating, and Air Conditioning 
Engineers, Inc.).

[[Page 183]]

                         Section 3. Definitions

    3.1 Recovered refrigerant. Refrigerant that has been removed from a 
system for the purpose of storage, recycling, reclamation or 
transportation.
    3.2 Recover. Reference 40 CFR 82.152.
    3.3 Recycle. Reference 40 CFR 82.152.
    3.4 Reclaim. Reference 40 CFR 82.152.
    3.5 Standard Contaminated Refrigerant Sample. A mixture of new and/
or reclaimed refrigerant and specified quantities of identified 
contaminants which are representative of field obtained, used 
refrigerant samples and which constitute the mixture to be processed by 
the equipment under test.
    3.6 Push/Pull Method. The push/pull refrigerant recovery method is 
defined as the process of transferring liquid refrigerant from a 
refrigeration system to a receiving vessel by lowering the pressure in 
the vessel and raising the pressure in the system, and by connecting a 
separate line between the system liquid port and the receiving vessel.
    3.7 Recycle Rate. The amount of refrigerant processed (in pounds) 
divided by the time elapsed in the recycling mode in pounds per minute. 
For equipment which uses a separate recycling sequence, the recycle rate 
does not include the recovery rate (or elapsed time). For equipment 
which does not use a separate recycling sequence, the recycle rate is a 
maximum rate based solely on the higher of the liquid or vapor recovery 
rate, by which the rated contaminant levels can be achieved.
    3.8 Equipment Classification.
    3.8.1 Self Contained Equipment. A refrigerant recovery or recycling 
system which is capable of refrigerant extraction without the assistance 
of components contained within an air conditioning or refrigeration 
system.
    3.8.2 System Dependent Equipment. Refrigerant recovery equipment 
which requires for its operation the assistance of components contained 
in an air conditioning or refrigeration system.
    3.9 ``Shall'', ``Should'', ``Recommended'' or ``It is Recommended'', 
``Shall'' ``Should'', ``recommended'', or ``it is recommended'' shall be 
interpreted as follows:
    3.9.1 Shall. Where ``shall'' or ``shall not'' is used for a 
provision specified, that provision is mandatory if compliance with the 
standard is claimed.
    3.9.2 Should, Recommended, or It is Recommended, ``Should'', 
``recommended'', is used to indicate provisions which are not mandatory 
but which are desirable as good practice.

                Section 4. General Equipment Requirements

    4.1 The equipment manufacturer shall provide operating instructions, 
necessary maintenance procedures, and source information for replacement 
parts and repair.
    4.2 The equipment shall indicate when any filter/drier(s) needs 
replacement. This requirement can be met by use of a moisture transducer 
and indicator light, by use of a sight glass/moisture indicator, or by 
some measurement of the amount of refrigerant processed such as a flow 
meter or hour meter. Written instructions such as ``to change the filter 
every 400 pounds, or every 30 days'' shall not be acceptable except for 
equipment in large systems where the Liquid Recovery Rate is greater 
than 25 lbs/min [11.3 Kg/min] where the filter/drier(s) would be changed 
for every job.
    4.3 The equipment shall either automatically purge non-condensables 
if the rated level is exceeded or alert the operator that the non-
condensable level has been exceeded. While air purge processes are 
subject to the requirements of this section, there is no specific 
requirement to include an air purge process for ``recycle'' equipment.
    4.4 The equipment's refrigerant loss due to non-condensable purging 
shall not be exceeded 5% by weight of total recovered refrigerant. (See 
Section 9.4)
    4.5 Internal hose assemblies shall not exceed a permeation rate of 
12 pounds mass per square foot [5.8 g/cm \2\] of internal surface per 
year at a temperature of 120 F [48.8 [deg]C] for any designated 
refrigerant.
    4.6 The equipment shall be evaluated at 75 F [24 [deg]C] per 7.1. 
Normal operating conditions range from 50 [deg]F to 104 F [10 [deg]C to 
40 [deg]C].
    4.7 Exemptions:
    4.7.1 Equpment intended for recovery only shall be exempt from 
sections 4.2 and 4.3.

                  Section 5. Contaminated Refrigerants

    5.1 The standard contaminated refrigerant sample shall have the 
characteristics specified in Table 1, except as provided in 5.2
    5.2 Recovery equipment not rated for any specific contaminant can be 
tested with new or reclaimed refrigerant.

                        Section 6. Test Apparatus

    6.1 Self Contained Equipment Test Apparatus. The apparatus as shown 
in Figure 1 consists of a 3 cubic foot [0.085 m\3\] mixing chamber with 
a conical-shaped bottom, although a larger mixing chamber is 
permissible. The size of the mixing chamber depends upon the size of the 
equipment. The outlet at the bottom of the cone and all restrictions and 
valves for liquid and vapor refrigerant lines in the test apparatus 
shall be a minimum of 0.375 in. [9.5 mm] inside diameter or equivalent. 
The minimum inside diameter for large equipment for use on chillers 
shall be 1.5 in. [38 mm.]. The mixing chamber shall contain various 
ports for receiving liquid refrigerant, oil, and contaminants. A 
recirculating line connected from the bottom outlet through a 
recirculating pump and then to a top vapor port shall be provided for 
stirring of the mixture. Isolation valves may be required for the pump. 
Alternative stirring means may be used if demonstrated to be equally 
effective.
    6.1.1 For liquid refrigerant feed, the liquid valve is opened. For 
vapor refrigerant feed, the vapor valve is opened and refrigerant passes 
through an evaporator coil. Flow is controlled by a thermostatic 
expansion valve to create 5 F [3 [deg]C] superheat at an evaporator 
temperature of 70 F 3 F[21 [deg]C2[deg]]. The evaporator coil or equivalent evaporator 
means shall be either sized large enough for the largest system or be 
sized for each system.
    6.1.2 An alternative method for vapor refrigerant feed is to pass 
through a boiler and then an automatic pressure regulating valve set at 
refrigerant saturation pressure at 75 F 3 F [24 
[deg]C 2 [deg]C].
    6.2 System Dependent Equipment Test Apparatus. This test apparatus 
is to be used for final recovery vacuum rating of all system dependent 
equipment.
    6.2.1 The test apparatus shown in Figure 2 consists of a complete 
refrigeration system. The manufacturer shall identify the refrigerants 
to be tested. The test apparatus can be modified to facilitate operation 
or testing of the system dependent equipment if the modifications to the 
apparatus are specifically described within the manufacturer's 
literature. (See Figure 2.) A \1/4\ inch [6.3 mm] balance line shall be 
connected across the test apparatus between the high and low pressure 
sides, with an isolation valve located at the connection to the 
compressor high side. A \1/4\ inch [6.3 mm] access port with a valve 
core shall be located in the balance line for the purpose of measuring 
final recovery vacuum at the conclusion of the test.

                     Section 7. Performance Testing

    7.1 Contaminant removal and performance testing shall be conducted 
at 75 F 2 F [23.9 [deg]C 1.1 
[deg]C].
    7.1.1 The equipment shall be prepared for operation per the 
instruction manual.
    7.1.2 The contaminated sample batch shall consist of not less than 
the sum of the amounts required to complete steps 7.1.2.2 and 7.1.2.3 
below.
    7.1.2.1 A liquid sample shall be drawn from the mixing chamber prior 
to starting the test to assure quality control of the mixing process.
    7.1.2.2 Vapor refrigerant feed testing, if elected, shall normally 
be processed first. After the equipment reaches stabilized conditions of 
condensing temperature and/or storage tank pressure, the vapor feed 
recovery rate shall be measured. One method is to start measuring the 
vapor refrigerant recovery rate when 85% of refrigerant remains in the 
mixing chamber and continue for a period of time sufficient to achieve 
the accuracy in 9.2. If liquid feed is not elected, complete Step 
7.1.2.4.
    7.1.2.3 Liquid refrigerant feed testing, if elected, shall be 
processed next. After the equipment reaches stabilized conditions, the 
liquid feed recovery rate shall be measured. One method is to wait 2 
minutes after starting liquid feed and then measure the liquid 
refrigerant recovery rate for a period of time sufficient to achieve the 
accuracy in 9.1. Continue liquid recovery operation as called for in 
7.1.2.4.
    7.1.2.4 Continue recovery operation until all liquid is removed from 
the mixing chamber and vapor is removed to the point where the equipment 
shuts down per automatic means or is manually stopped per the operating 
instructions.
    7.1.2.5 After collecting the first contaminated refrigerant sample 
batch, the liquid and vapor value of the apparatus shall be closed and 
the mixing chamber pressure recorded after 1 minute as required in 9.5. 
After preparing a second contaminated refrigerant sample batch, continue 
recovery until the storage container reaches 80% liquid fill level. 
After recycling and measuring

[[Page 187]]

the recycle rate per section 7.1.3, set this container aside for the 
vapor sample in 8.2.2.
    7.1.2.6 Interruptions in equipment operations as called for in 
instruction manual are allowable.
    7.1.3 Recycle as called for in equipment operating instructions. 
Determine recycle rate by appropriate means as required in 9.3.
    7.1.4 Repeat steps 7.1.2, 7.1.2.4, and 7.1.3 with contaminated 
refrigerant sample until equipment indicator(s) show need to change 
filter(s). It will not be necessary to repeat the recycle rate 
determination in 7.1.3.
    7.1.4.1 For equipment with a multiple pass recirculating filter 
system, analyze the contents of the previous storage container.
    7.1.4.2 For equipment with a single pass filter system, analyze the 
contents of the current storage container.
    7.1.5 Refrigerant loss due to the equipment's non-condensable gas 
purge shall be determined by appropriate means. (See Section 9.4.)
    7.2 System Dependent Equipment. This procedure shall be used for 
vacuum rating of all system dependent equipment. Liquid refrigerant 
recovery rate, vapor refrigerant recovery rate, and recycle rate are not 
tested on system dependent systems.
    7.2.1 The apparatus operation and testing shall be conducted at 75 F 
2 F. [23.9 [deg]C. /1.1. 
[deg]C.].
    7.2.2 The apparatus shall be charged with refrigerant per its system 
design specifications.
    7.2.3 For measurement of final recovery vacuum as required in 9.5, 
first shut the balance line isolation valve and wait 1 minute for 
pressure to balance. Then connect and operate the recovery system per 
manufacturers recommendations. When the evacuation is completed, open 
the balance line isolation valve and measure the pressure in the balance 
line.

            Section 8. Sampling and Chemical Analysis Methods

    8.1 The referee test methods for the various contaminants are 
summarized in the following paragraphs. Detailed test procedures are 
included in Appendix A ``Test Procedures for ARI STD 700.'' If alternate 
test methods are employed, the user must be able to demonstrate that 
they produce results equivalent to the specified referee method.
    8.2 Refrigerant Sampling.
    8.2.1 Sampling Precautions. Special precautions should be taken to 
assure that representative samples are obtained for analysis. Sampling 
shall be done by trained laboratory personnel following accepted 
sampling and safety procedures.
    8.2.2 Gas Phase Sample. A gas phase sample shall be obtained for 
determining the non-condensables. Since non-condensable gases, if 
present, will concentrate in the vapor phase of the refrigerant, care 
must be exercised to eliminate introduction of air during the sample 
transfer. Purging is not and acceptable procedure for a gas phase sample 
since it may introduce a foreign product. Since R11, R113 and R123 have 
normal boiling points at or above room temperature, noncondensable 
determination is not required for these refrigerants.
    8.2.2.1 The sample cylinder shall be connected to an evacuated gas 
sampling bulb by means of a manifold. The manifold should have a valve 
arrangement that facilitates evacuation of all connecting tubing leading 
to the sampling bulb.
    8.2.2.2 After the manifold has been evacuated, close the valve to 
the pump and open the valve on the system. Allow the pressure to 
equilibrate and close valves.
    8.2.3 Liquid Phase Sample. A liquid phase sample is required for all 
tests listed in this standard, except the test for non-condensables.
    8.2.3.1 Place an empty sample cylinder with the valve open in an 
oven at 230 F [110 [deg]C] for one hour. Remove it from the oven while 
hot, immediately connect to an evacuation system and evacuate to less 
than 1mm. mercury (1000 microns). Close the valve and allow it to cool.
    8.2.3.2 The valve and lines from the unit to be sampled shall be 
clean and dry. Connect the line to the sample cylinder loosely. Purge 
through the loose connection. Make the connection tight at the end of 
the purge period. Take the sample as a liquid by chilling the sample 
cylinder slightly. Accurate analysis requires that the sample container 
be filled to at least 60% by volume; however under no circumstances 
should the cylinder be filled to more than 80% by volume. This can be 
accomplished by weighing the empty cylinder and then the cylinder with 
refrigerant. When the desired amount of refrigerant has been collected, 
close the valve(s) and disconnect the sample cylinder immediately.
    8.2.3.3 Check the sample cylinder for leaks and record the gross 
weight.
    8.3 Water Content.
    8.3.1. The Coulometric Karl Fischer Titration shall be the primary 
test method for determining the water content of refrigerants. This 
method is described in Appendix A. This method can be used for 
refrigerants that are either a liquid or a gas at room temperature, 
including Refrigerants 11 and 13. For all refrigerants, the sample for 
water analysis shall be taken from the liquid phase of the container to 
be tested. Proper operation of the analytical method requires special 
equipment and an experienced operator. The precision of the results is 
excellent if proper sampling and handling procedures are followed. 
Refrigerants containing a colored dye can be successfully analyzed for 
water using this method.

[[Page 188]]

    8.3.2 The Karl Fischer Test Method is an acceptable alternative test 
method for determining the water content of refrigerants. This method is 
described in ASTM Standard for ``Water in gases Using Karl Fisher 
Reagent'' E700-79, reapproved 1984 (American Society for Testing and 
Materials, Philadelphia, PA).
    8.3.3 Report the moisture level in parts per million by weight if a 
sample is required.
    8.4 Chloride. The refrigerant shall be tested for chlorides as an 
indication of the presence of hydrochloric or similar acids. The 
recommended procedure is intended for use with new or reclaimed 
refrigerants. Significant amounts of oil may interfere with the results 
by indicating a failure in the absence of chlorides.
    8.4.1 The test method shall be that described in Appendix A ``Test 
Procedures for ARI-700.'' The test will show noticeable turbidity at 
equivalent chloride levels of about 3 ppm by weight or higher.
    8.4.2 The results of the test shall not exhibit any sign of turbity. 
Report results as ``pass'' or ``fail.''
    8.5 Acidity.
    8.5.1 The acidity test uses the titration principle to detect any 
compound that is highly soluble in water and ionizes as an acid. The 
test method shall be that described in Appendix A. ``Test Procedures for 
ARI-700.'' The test may not be suitable for determination of high 
molecular weight organic acids; however these acids will be found in the 
high boiling residue test outlined in Section 5.7. The test requires 
about a 100 to 120 gram sample and has a low detection limit of 0.1 ppm 
by weight as HC1.
    8.6 High Boiling Residue.
    8.6.1 High boiling residue will be determined by measuring the 
residue of a standard volume of refrigerant after evaporation. The 
refrigerant sample shall be evaporated at room temperature or a 
temperature 50 F [10[deg].0C], above the boiling point of the sample 
using a Goetz tube as specified in Appendix A ``Test Procedures for ARI-
700.'' Oils and or organic acids will be captured by this method.
    8.6.2 The value for high boiling residue shall be expressed as a 
percentage by volume.
    8.7 Particulates/Solids.
    8.7.1 A measured amount of sample is evaporated from a Goetz bulb 
under controlled temperature conditions. The particulates/solids shall 
be determined by visual examination of the empty Goetz bulb after the 
sample has evaporated completely. Presence of dirt, rust or other 
particulate contamination is reported a ``fail.'' For details of this 
test method, refer to Appendix B ``Test Procedures for ARI-700.''
    8.8 Non-Condensables
    8.8.1 A vapor phase sample shall be used for determination of non-
condensables. Non-condensable gases consist primarily of air accumulated 
in the vapor phase of refrigerant containing tanks. The solubility of 
air in the refrigerants liquid phase is extremely low and air is not 
significant as a liquid phase contaminant. The presence of non-
condensable gases may reflect poor quality control in transferring 
refrigerants to storage tanks and cylinders.
    8.8.2 The test method shall be gas chromatography with a thermal 
conductivity detector as described in Appendix A ``Test Procedures for 
ARI-700.''
    8.8.2.1 The Federal Specification for ``Fluorocarbon Refrigerants,'' 
BB-F-1421B, dated March 5, 1992, section 4.4.2 (perchloroethylene 
method) is an acceptable alternate test method.
    8.8.3 Report the level of non-condensable as percent by volume.

              Section 9. Performance Calculation and Rating

    9.1 The liquid refrigerant recovery rate shall be expressed in 
pounds per minute [kg/min] and measured by weight change at the mixing 
chamber (See Figure 1) divided by elapsed time to an accuracy within .02 
lbs/min. [.009 kg/min]. Ratings using the Push/Pull method shall be 
identified ``Push/Pull''. Equipment may be rated by both methods.
    9.2 The vapor refrigerant recovery rate shall be expressed in pounds 
per minute [kg/min] and measured by weight change at the mixing chamber 
(See Figure 1) divided by elapsed time to an accuracy within .02 lbs/
min. [.0.009 kg/min].
    9.3 The recycle rate is defined in 3.7 and expressed in pounds per 
minute [kg/min] of flow and shall be per ASHRAE 41.7-84 ``Procedure For 
Fluid Measurement Of Gases'' or ASHRAE 41.8-89 ``Standard Method of Flow 
of Fluids--Liquids.''
    9.3.1 For equipment using multipass recycling or a separate 
sequence, the recycle rate shall be determined by dividing the net 
weight W of the refrigerant to be recycled by the actual time T required 
to recycle the refrigerant. Any set-up or operator interruptions shall 
not be included in the time T. The accuracy of the recycle rate shall be 
within .02 lbs/min. [.009 kg/min].
    9.3.2 If no separate recycling sequence is used, the recycle rate 
shall be the higher of the vapor refrigerant recovery rate or the liquid 
refrigerant recovery rate. The recycle rate shall match a process which 
leads to contaminant levels in 9.6. Specifically, a recovery rate 
determined from bypassing a contaminant removal device cannot be used as 
a recycle rate when the contaminant levels in 9.6 are determined by 
passing the refrigerant through the containment removal device.
    9.4 Refrigerant loss due to non-condensable purging shall be less 
than 5%. This rating shall be expressed as ``passed'' if less than 5%.

[[Page 189]]

    This calculation will be based upon net loss of non-condensables and 
refrigerant due to the purge divided by the initial net content. The net 
loss shall be determined by weighing before and after the purge, by 
collecting purged gases, or an equivalent method.
    9.5 The final recovery vacuum shall be the mixing chamber pressure 
called for in 7.1.2.5 expressed in inches of mercury vacuum, [mm Hg or 
kP]. The accuracy of the measurement shall be within .1 inch [2.5mm] of Hg and rounding 
down to the nearest whole number.
    9.6 The contaminant levels remaining after testing shall be 
published as follows:

Moisture content, PPM by weight
Chloride ions, Pass/Fail
Acidity, PPM by weight
High boiling residue, percentage by volume
Particulate/solid, Pass/Fail
Non-condensables, % by volume

    9.7 Product Literature: Except as provided under product labelling 
in Section 11. performance ratings per 9.1, 9.2, 9.3, and 9.5 must be 
grouped together and shown for all listed refrigerants (11.2) subject to 
limitations of 9.8. Wherever any contaminant levels per 9.6 are rated, 
all ratings in 9.6 must be shown for all listed refrigerants subject to 
limitations of 9.8. The type of equipment in 11.1 must be included with 
either grouping. Optional ratings in 9.8 need not be shown.
    9.8 Ratings shall include all of the parameters for each designed 
refrigerant in 11.2 as shown in Tables 2 and 3.

[[Page 190]]

                      1. Particulate Specification

    1.1 The particulate material pm will be a blend of 50% coarse air 
cleaner dust as received, and 50% retained on a 200-mesh screen. The 
coarse air cleaner dust is available from: AC Spark Plug Division, 
General Motors Corporation, Flint, Michigan.

                1.2 Preparation of Particulate Materials

    To prepare the blend of contaminant, first wet screen a quantity of 
coarse air cleaner dust on a 200-mesh screen (particle retention 74 pm). 
This is done by placing a portion of the dust on a 200-mesh screen and 
running water through the screen while stirring the dust with the 
fingers. The fine contaminant particles passing through the screen are 
discarded. The +200 mesh particles collected on the screen are removed 
and dried for one hour at 230 F [110 [deg]C]. The blend of standard 
contaminant is prepared by mixing 50% by weight of coarse air cleaner 
dust as received after drying for one hour at 230 F [110 [deg]C] with 
50% by weight of the +200 mesh screened dust.
    1.3 The coarse air cleaner dust as received and the blend used as 
the standard contaminant have the following approximate particle size 
analysis: Wt. % in various size ranges, pm.

    Appendix B2 to Subpart F of Part 82--Performance of Refrigerant 
              Recovery, Recycling, and/or Reclaim Equipment

    This appendix is based on the Air-Conditioning and Refrigeration 
Institute Standard 740-1995.

                           Section 1. Purpose

    1.1 Purpose. The purpose of this standard is to establish methods of 
testing for rating and evaluating the performance of refrigerant 
recovery, and/or recycling equipment and general equipment requirements 
(herein referred to as ``equipment'') for contaminant or purity levels, 
capacity, speed and purge loss to minimize emission into the atmosphere 
of designated refrigerants.

                            Section 2. Scope

    2.1 Scope. This standard applies to equipment for recovering and/or 
recycling single refrigerants, azeotropics, zeotropic blends, and their 
normal contaminants from refrigerant systems. This standard defines the 
test apparatus, test gas mixtures, sampling procedures and analytical 
techniques that will be used to determine the performance of refrigerant 
recovery and/or recycling equipment (hereinafter, ``equipment'').

                         Section 3. Definitions

    3.1 Definitions. All terms in this appendix will follow the 
definitions in Sec.82.152 unless otherwise defined in this appendix.
    3.2 Clearing Refrigerant. Procedures used to remove trapped 
refrigerant from equipment before switching from one refrigerant to 
another.
    3.3 High Temperature Vapor Recovery Rate. For equipment having at 
least one designated refrigerant (see 11.2) with a boiling point in the 
range of -50 to +10 [deg]C, the rate will be measured for R-22, or the 
lowest boiling point refrigerant if R-22 is not a designated 
refrigerant.
    3.4 Published Ratings. A statement of the assigned values of those 
performance characteristics, under stated rating conditions, by which a 
unit may be chosen to fit its application. These values apply to all 
units of like nominal size and type (identification) produced by the 
same manufacturer. As used herein, the term ``published rating'' 
includes the rating of all performance characteristics shown on the unit 
or published in specifications, advertising or other literature 
controlled by the manufacturer, at stated rating conditions.
    3.5 Push/Pull Method. The push/pull refrigerant recovery method is 
defined as the process of transferring liquid refrigerant from a 
refrigeration system to a receiving vessel by lowering the pressure in 
the vessel and raising the pressure in the system, and by connecting a 
separate line between the system liquid port and the receiving vessel.
    3.6 Recycle Flow Rate. The amount of refrigerant processed divided 
by the time elapsed in the recycling mode. For equipment which uses a 
separate recycling sequence, the recycle rate does not include the 
recovery rate (or elapsed time). For equipment which does not use a 
separate recycling sequence, the recycle rate is a rate based solely on 
the higher of the liquid or vapor recovery rate, by which the 
contaminant levels were measured.
    3.7 Residual Trapped Refrigerant. Refrigerant remaining in equipment 
after clearing.
    3.8 Shall, Should, Recommended or It Is Recommended shall be 
interpreted as follows:
    3.8.1 Shall. Where ``shall'' or ``shall not'' is used for a 
provision specified, that provision

[[Page 191]]

is mandatory if compliance with this appendix is claimed.
    3.8.2 Should, Recommended or It Is Recommended is used to indicate 
provisions which are not mandatory but which are desirable as good 
practice.
    3.9 Standard Contaminated Refrigerant Sample. A mixture of new or 
reclaimed refrigerant and specified quantities of identified 
contaminants which constitute the mixture to be processed by the 
equipment under test. These contaminant levels are expected only from 
severe service conditions.
    3.10 Trapped Refrigerant. The amount of refrigerant remaining in the 
equipment after the recovery or recovery/recycling operation but before 
clearing.
    3.11 Vapor Recovery Rate. The average rate that refrigerant is 
withdrawn from the mixing chamber between two pressures as vapor 
recovery rate is changing pressure and temperature starting at saturated 
conditions either 24 [deg]C or at the boiling point 100 kPa (abs), 
whichever is higher. The final pressure condition is 10% of the initial 
pressure, but not lower than the equipment final recovery vacuum and not 
higher than 100 kPa (abs).

                Section 4. General Equipment Requirements

    4.1 Equipment Information. The equipment manufacturer shall provide 
operating instructions, necessary maintenance procedures and source 
information for replacement parts and repair.
    4.2 Filter Replacement. The equipment shall indicate when any 
filter/drier(s) needs replacement. This requirement can be met by use of 
a moisture transducer and indicator light, by use of a sight glass/
moisture indicator or by some measurement of the amount of refrigerant 
processed such as a flow meter or hour meter. Written instructions such 
as ``to change the filter every 181 kg, or every 30 days'' shall not be 
acceptable except for equipment in large systems where the liquid 
recovery rate is greater than 11.3 kg/min where the filter/drier(s) 
would be changed for every job.
    4.3 Purge of Non-Condensable. If non-condensables are purged, the 
equipment shall either automatically purge non-condensables or provide 
indicating means to guide the purge process.
    4.4 Purge Loss. The total refrigerant loss due to purging non-
condensables, draining oil and clearing refrigerant (see 9.5) shall be 
less than 3% (by weight) of total processed refrigerant.
    4.5 Permeation Rate. High pressure hose assemblies \5/8\ in. [16 mm] 
nominal and smaller shall not exceed a permeation rate of 3.9 g/cm\2\/yr 
(internal surface) at a temperature of 48.8 [deg]C. Hose assemblies that 
UL recognized as having passed ANSI/UL 1963 requirements shall be 
accepted without testing. See 7.1.4.
    4.6 Clearing Trapped Refrigerant. For equipment rated for more than 
one refrigerant, the manufacturer shall provide a method and 
instructions which will accomplish connections and clearing within 15 
minutes. Special equipment, other than a vacuum pump or manifold gauge 
set shall be furnished. The clearing procedure shall not rely upon the 
storage cylinder below saturated pressure conditions at ambient 
temperature.
    4.7 Temperature. The equipment shall be evaluated at 24 [deg]C with 
additional limited evaluation at 40 [deg]C. Normal operating conditions 
range from 10 [deg]C to 40 [deg]C.
    4.8 Exemptions. Equipment intended for recovery only shall be exempt 
from 4.2 and 4.3.

                  Section 5. Contaminated Refrigerants

    5.1 Sample Characteristics. The standard contaminated refrigerant 
sample shall have the characteristics specified in Table 1, except as 
provided in 5.2.
    5.2 Recovery-Only Testing. Recovery equipment not rated for any 
specific contaminant shall be tested with new or reclaimed refrigerant.

                        Section 6. Test Apparatus

    6.1 General Recommendations. The recommended test apparatus is 
described in the following paragraphs. If alternate test apparatus are 
employed, the user shall be able to demonstrate that they produce 
results equivalent to the specified referee apparatus.
    6.2 Self-Contained Equipment Test Apparatus. The apparatus, shown in 
Figure 1, shall consist of:

    6.3 Size. The size of the mixing chamber shall be a minimum of .09 
m\3\. The bottom port and the refrigerant feed shall depend on the size 
of the equipment. Typically, the mixing valves and piping shall be 9.5 
mm. For large equipment to be used on chillers, the minimum inside 
diameter of ports, valves and pipings shall be the smaller of the 
manufacturer's recommendation or 37 mm.
    6.4 System Dependent Equipment Test Apparatus. This test apparatus 
is to be used for final recovery vacuum rating of all system dependent 
equipment.

[[Page 194]]

    6.4.1 Test Setup. The test apparatus shown in Figure 2 consists of a 
complete refrigeration system. The manufacturer shall identify the 
refrigerants to be tested. The test apparatus can be modified to 
facilitate operation or testing of the system dependent equipment if the 
modifications to the apparatus are specifically described within the 
manufacturer's literature. (See Figure 2.) A 6.3 mm balance line shall 
be connected across the test apparatus between the high and low-pressure 
sides, with an isolation valve located at the connection to the 
compressor high side. A 6.3 mm access port with a valve core shall be 
located in the balance line for the purpose of measuring final recovery 
vacuum at the conclusion of the test.

                     Section 7. Performance Testing

    7.1 General Testing.
    7.1.1 Temperatures. Testing shall be conducted at an ambient 
temperature of 24 [deg]C 1K except high 
temperature vapor recovery shall be at 40 [deg]C 1K. The evaporator conditions of 6.2.3 shall be 
maintained as long as liquid refrigerant remains in the mixing chamber.
    7.1.2 Refrigerants. The equipment shall be tested for all designated 
refrigerants (see 11.2). All tests in Section 7 shall be completed for 
each refrigerant before starting tests with the next refrigerant.
    7.1.3 Selected Tests. Tests shall be as appropriate for the 
equipment type and ratings parameters selected (see 9.9, 11.1 and 11.2).
    7.1.4 Hose Assemblies. For the purpose of limiting refrigerant 
emissions to the atmosphere, hose assemblies shall be tested for 
permeation according to ANSI/UL Standard 1963, Section 40.10.
    7.2 Equipment Preparation and Operation. The equipment shall be 
prepared and operated per the operating instructions.
    7.3 Test Batch. The test batch consisting of refrigerant sample (see 
Section 5) of the test refrigerant shall be prepared and thoroughly 
mixed. Continued mixing or stirring shall be required during the test 
while liquid refrigerant remains in the mixing chamber. The mixing 
chamber shall be filled to 80% level by volume.
    7.3.1 Control Test Batch. Prior to starting the test for the first 
batch for each refrigerant, a liquid sample will be drawn from the 
mixing chamber and analyzed per Section 8 to assure that contaminant 
levels match Table 1 within 10 ppm for moisture, 
20 ppm for particulate, 20 
ppm for oleic acid and 0.5% for oil.
    7.4 Recovery Tests (Recovery and Recovery/Recycle Equipment).
    7.4.1 Determining Recovery Rates. The liquid and vapor refrigerant 
recovery rates shall be measured during the first test batch for each 
refrigerant (see 9.1, 9.2 and 9.4). Equipment preparation and recovery 
cylinder changeover shall not be included in elapsed time measurements 
for determining vapor recovery rate and liquid refrigerant recovery 
rate. Operations such as subcooling the recovery cylinder shall be 
included. Recovery cylinder shall be the same size as normally furnished 
or specified in the instructions by the equipment manufacturer. 
Oversized tanks shall not be permitted.
    7.4.1.1 Liquid Refrigerant Recovery Rate. If elected, the recovery 
rate using the liquid refrigerant feed means (see 6.2.5) shall be 
determined. After the equipment reaches stabilized conditions of 
condensing temperature and/or recovery cylinder pressure, the recovery 
process shall be stopped and an initial weight shall be taken of the 
mixing chamber (see 9.2). The recovery process shall be continued for a 
period of time sufficient to achieve the accuracy in 9.4. The recovery 
process shall be stopped and a final weight shall be taken of the mixing 
chamber.

[[Page 195]]

[GRAPHIC] [TIFF OMITTED] TR24JY03.008

    7.4.1.2 Vapor Refrigerant Recovery Rate. If elected, the average 
vapor flow rate shall be measured to accuracy requirements in clause 9.4 
under conditions with no liquid refrigerant in the mixing chamber. The 
liquid recovery feed means shall be used. At initial conditions of 
saturated vapor at the higher of 24 [deg]C or the boiling temperature 
(100 kPa absolute pressure), the weight of the mixing chamber and the 
pressure shall be recorded. At final conditions representing pressure in 
the mixing chamber of 10% of the initial condition, but not less than 
the final recovery vacuum (see 9.6) nor more than 100 kPa, measure the 
weight of the mixing chamber and the elapsed time.
    7.4.1.3 High Temperature Vapor Recovery Rate. Applicable for 
equipment having at least one designated refrigerant (see 11.2) with a 
boiling point between -50 [deg]C and +10 [deg]C. Measure the rate for R-
22, or the refrigerant with the lowest boiling point if R-22 is not a 
designated refrigerant. Repeat the test in 7.4.1.2 at saturated 
conditions at 40 [deg]C and continue to operate equipment to assure it 
will achieve the final recovery vacuum (see 7.4.3).
    7.4.2 Recovery Operation. This test is for determining the final 
recovery vacuum and the ability to remove contaminants as appropriate. 
If equipment is rated for liquid recovery (see 7.4.1.3), liquid recovery 
feed means described in 6.2.5 shall be used. If not, vapor recovery 
means described in 6.2.3 or 6.2.4 shall be used. Continue recovery 
operation until all liquid is removed from the test apparatus and vapor 
is removed to the point where equipment shuts down by automatic means or 
is manually shut off per operating instructions.
    7.4.2.1 Oil Draining. Capture oil from the equipment at intervals as 
required in the instructions. Record the weight of the container. 
Completely remove refrigerant from oil by evacuation or other 
appropriate means. The weight difference shall be used in 9.5.2.
    7.4.3 Final Recovery Vacuum. At the end of the first test batch for 
each refrigerant, the liquid valve and vapor valve of the apparatus 
shall be closed. After waiting 1 minute, the mixing chamber pressure 
shall be recorded (see 9.6).
    7.4.4 Residual Refrigerant. This test will measure the mass of 
remaining refrigerant in the equipment after clearing and therefore the 
potential for mixing refrigerants (see 4.6).

[[Page 196]]

    7.4.4.1 Initial Conditions. At the end of the last test for each 
batch for each refrigerant, the equipment shall be disconnected from the 
test apparatus (Figure 1). Recycle per 7.5, if appropriate. Perform 
refrigerant clearing operations as called for in the instruction manual. 
Capture and record the weight of any refrigerant which would have been 
emitted to the atmosphere during the clearing process for use in 9.5. If 
two loops are used for recycling, trapped refrigerant shall be measured 
for both.
    7.4.4.2 Residual Trapped Refrigerant. Evacuate an empty test 
cylinder to 1.0 kPa absolute. Record the empty weight of the test 
cylinder. Open all valves to the equipment so as to provide access to 
all trapped refrigerant. Connect the equipment to the test cylinder and 
operate valves to recover the residual refrigerant. Record the weight of 
the test cylinder using a recovery cylinder pressure no less than 
specified in 6.2.2. Place the test cylinder in liquid nitrogen for a 
period of 30 minutes or until a vacuum of 1000 microns is reached, 
whichever occurs first.
    7.5 Recycling Tests (Recovery/Recycle Equipment).
    7.5.1 Recycling Operation. As each recovery cylinder is filled in 
7.4.2, recycle according to operating instructions. There will not 
necessarily be a separate recycling sequence. Note non-condensable purge 
measurement in 9.5.
    7.5.1.1 Recycle Flow Rate. While recycling the first recovery 
cylinder for each refrigerant, determine the recycling flow rate by 
appropriate means (see 9.3) to achieve the accuracy required in 9.4.
    7.5.2 Non-Condensable Sample. After completing 7.4.3, prepare a 
second test batch (7.3). Recover per 7.4.2 until the current recovery 
cylinder is filled to 80% level by volume. Recycle per 7.5.1. Mark this 
cylinder and set aside for taking the vapor sample. For equipment having 
both an internal tank of at least 3 kg refrigerant capacity and an 
external recovery cylinder, two recovery cylinders shall be marked and 
set aside. The first is the cylinder described above. The second 
cylinder is the final recovery cylinder after filling it to 80% level by 
volume and recycling.
    7.5.3 Liquid Sample for Analysis. Repeat steps 7.3, 7.4.2 and 7.5.1 
with further test batches until indication means in 4.2 show the filter/
drier(s) need replacing.
    7.5.3.1 Multiple Pass. For equipment with a separate recycling 
circuit (multiple pass), set aside the current cylinder and draw the 
liquid sample (see 7.4) from the previous cylinder.
    7.5.3.2 Single Pass. For equipment with the single pass recycling 
circuit, draw the liquid sample (see 7.4) from the current cylinder.
    7.6 Measuring Refrigerant Loss. Refrigerant loss due to non-
condensables shall be determined by appropriate means (see 9.5.1). The 
loss could occur in 7.4.1, 7.4.2 and 7.5.1.

            Section 8. Sampling and Chemical Analysis Methods

    8.1 Chemical Analysis. Chemical analysis methods shall be specified 
in appropriate standards such as ARI 700-95 and Appendix C to ARI 
Standard 700-95.
    8.2 Refrigerant Sampling.
    8.2.1 Water Content. The water content in refrigerant shall be 
measured by the Karl Fischer Analytical Method or by the Karl Fischer 
Coulometric techniques. Report the moisture level in parts per million 
by weight.
    8.2.2 Chloride Ions. Chloride ions shall be measured by turbidity 
tests. At this time, quantitative results have not been defined. Report 
chloride content as ``pass'' or ``fail.'' In the future, when 
quantitative results are possible, report chloride content as parts per 
million by weight.
    8.2.3 Acidity. The acidity test uses the titration principle. Report 
the acidity in parts per million by weight (mg KOH/kg) of sample.
    8.2.4 High Boiling Residue. High boiling residues shall use 
measurement of the volume of residue after evaporating a standard volume 
of refrigerant. Using weight measurement and converting to volumetric 
units is acceptable. Report high boiling residues as percent by volume.
    8.2.5 Particulates/Solids. The particulates/solids measurement 
employs visual examination. Report results as ``pass'' or ``fail.''
    8.2.6 Non-condensables. The level of contamination by non-
condensable gases in the base refrigerant being recycled shall be 
determined by gas chromatography. Report results as percent by volume.

              Section 9. Performance Calculation and Rating

    9.1 Vapor Refrigerant Recovery Rate. This rate shall be measured by 
weight change of the mixing chamber divided by elapsed time (see 
7.4.1.2). The units shall be kg/min and the accuracy shall be per 9.4.
    9.1.1 High Temperature Vapor Recovery Rate.
    9.2 Liquid Refrigerant Recovery Rate. This rate shall be measured by 
weight change of the mixing chamber divided by elapsed time (see 
7.4.1.3). The units shall be kg/min and the accuracy shall be per 9.4.
    9.3 Recycle Flow Rate. The recycle flow rate shall be as defined in 
3.10, expressed in kg/min, and the accuracy shall be per 9.4.
    9.3.1 For equipment using multi-pass recycling or a separate 
sequence, the recycle rate shall be determined by dividing the net 
weight W of the refrigerant to be recycled by the actual time T required 
to recycle. Any set-up or operator interruptions shall not be included 
in the time T.

[[Page 197]]

    9.3.2 If no separate recycling sequence is used, the recycle rate 
shall be the higher of the vapor refrigerant recovery rate or the liquid 
refrigerant recovery rate. The recycle rate shall match a process which 
leads to contaminant levels in 9.9. Specifically, a recovery rate 
determined from bypassing a contaminant removal device cannot be used as 
a recycle rate when the contaminant levels in 9.9 are determined by 
passing the refrigerant through the contaminant removal device.
    9.4 Accuracy of Flow Rates. The accuracy of test measurements in 
9.1, 9.2 and 9.3 shall be 008 kg/min or flow rates 
up to .42 kg/min and 2.0% for flow rates larger 
than .42 kg/min. Ratings shall be expressed to the nearest .02 kg/min.
    9.5 Refrigerant Loss. This calculation will be based upon the net 
loss of refrigerant which would have been eliminated in the non-
condensable purge process (see 7.5.1), the oil draining process (see 
7.4.2.1) and the refrigerant clearing process (see 7.4.4.1), all divided 
by the net refrigerant content of the test batches. The refrigerant loss 
shall not exceed 3% by weight.
    9.5.1 Non-Condensable Purge. Evacuate an empty container to 2 kPa 
absolute. Record the empty weight of the container. Place the container 
in a dry ice bath. Connect the equipment purge connection to the 
container and operate purge according to operating instructions so as to 
capture the non-condensables and lost refrigerant. Weigh the cylinder 
after the recycling is complete. Equivalent means are permissible.
    9.5.2 Oil Draining. Refrigerant removed from the oil after draining 
shall be collected and measured in accordance with 7.4.2.1.
    9.5.3 Clearing Unit. Refrigerant captured during the clearing 
process shall be measured in accordance with 7.4.4.1.
    9.6 Final Recovery Vacuum. The final recovery vacuum shall be the 
mixing chamber pressure in 7.4.3 expressed in kPa. The accuracy of the 
measurement shall be within 0.33 kPa.
    9.7 Residual Trapped Refrigerant. The amount of residual trapped 
refrigerant shall be the final weight minus the initial weight of the 
test cylinder in 7.4.4.2, expressed in kg. The accuracy shall be 0.02 kg and reported to the nearest 0.05 kg.
    9.8 Quantity Recycled. The amount of refrigerant processed before 
changing filters (see 7.5.3) shall be expressed in kg to an accuracy of 
1%.
    9.9 Contaminant Levels. The contaminant levels remaining after 
testing shall be published as follows:
    Moisture content, ppm by weight
    Chloride ions, pass/fail
    Acidity, ppm by weight
    High boiling residue, % (by volume)
    Particulates-solid, pass/fail (visual examination)
    Non-condensables, % (by volume)
    9.10 Minimum Data Requirements for Published Ratings. Published 
ratings shall include all of the parameters as shown in Tables 2 and 3 
for each refrigerant designated by the manufacturer.

                         Section 10. Tolerances

    10.1 Tolerances. Performance related parameters shall not be less 
favorable than the published ratings.

                 Section 11. Marking and Nameplate Data

    11.1 Marking and Nameplate Data. The nameplate shall display the 
manufacturer's name, model designation, type of equipment, designated 
refrigerants, capacities and electrical characteristics where 
applicable. The nameplate shall also conform to the labeling 
requirements established for certified recycling and recovery equipment 
established at 40 CFR 82.158(h).
    Recommended nameplate voltages for 60 Hertz systems shall include 
one or more of the utilization voltages shown in Table 1 of ARI Standard 
110-90. Recommended nameplate voltages for 50 Hertz systems shall 
include one or more of the utilization voltages shown in Table 1 of IEC 
Standard Publication 38, IEC Standard Voltages.
    11.2 Data for Designated Refrigerants. For each refrigerant 
designated, the manufacturer shall include all the following that are 
applicable per Table 2:

a. Liquid Recovery Rate
b. Vapor Recovery Rate
c. High Temperature Vapor Recovery Rate

Attachment 2 to Appendix B2 to Subpart F of Part 82-Particulate Used in 
                Standard Contaminated Refrigerant Sample

                      1. Particulate Specification

    B1.1 The particulate material (pm) will be a blend of 50% coarse air 
cleaner dust as received, and 50% retained on a 200-mesh screen. The 
coarse air cleaner dust is available from: AC Spark Plug Division; 
General Motors Corporation; Flint, Michigan.
    B1.2 Preparation of Particulate Materials.
    To prepare the blend of contaminant, first wet screen a quantity of 
coarse air cleaner dust on a 200-mesh screen (particle retention 74 pm). 
This is done by placing a portion of the dust on a 200-mesh screen and 
running water through the screen while stirring the dust with the 
fingers. The fine contaminant particles passing through the screen are 
discarded. The +200-mesh particles collected on the screen are removed 
and dried for one hour at 110 [deg]C. The blend of standard contaminant

  Sec. Appendix B3 to Subpart F of Part 82--Performance of Refrigerant 
              Recovery, Recycling, and/or Reclaim Equipment

    This appendix is based on the Air-Conditioning, Heating, and 
Refrigeration Institute Standard 740-2016, Performance Rating of 
Refrigerant Recovery Equipment and Recovery/Recycling Equipment.

                           Section 1. Purpose

    1.1 The purpose of this standard is to establish methods of testing 
for rating and evaluating the performance of refrigerant recovery, and/
or recycling equipment and general equipment requirements (herein 
referred to as ``equipment'') for contaminant or purity levels, 
capacity, speed and purge loss to minimize emission into the atmosphere 
of designated refrigerants.

                            Section 2. Scope

    2.1 This standard applies to equipment for recovering and/or 
recycling single refrigerants, azeotropes, zeotropic blends, and their 
normal contaminants from refrigerant systems. This standard defines the 
test apparatus, test gas mixtures, sampling procedures and analytical 
techniques that will be used to determine the performance of refrigerant 
recovery and/or recycling equipment (hereinafter, ``equipment''). 
Appendix B4 of this subpart establishes standards for recovery/recycling 
equipment used with flammable refrigerants.

                         Section 3. Definitions

    3.1 Definitions. All terms in this appendix will follow the 
definitions in Sec.82.152 unless otherwise defined in this appendix.
    3.2 Clearing Refrigerant. Procedures used to remove trapped 
refrigerant(s) from equipment before switching from one refrigerant to 
another.
    3.3 High Temperature Vapor Recovery Rate. For equipment having at 
least one designated refrigerant (see Section 11.2 of this appendix) 
with a boiling point in the range of -50 to +10 [deg]C, the rate will be 
measured for R-22, or the lowest boiling point refrigerant if R-22 is 
not a designated refrigerant.
    3.4 Published Ratings. A statement of the assigned values of those 
performance characteristics, under stated rating conditions, by which a 
unit may be chosen to fit its application. These values apply to all 
units of like nominal size and type (identification) produced by the 
same manufacturer. As used herein, the term ``published rating'' 
includes the rating of all performance characteristics shown on the unit 
or published in specifications, advertising, or other literature 
controlled by the manufacturer, at stated rating conditions.
    3.5 Push/Pull Liquid Recovery. The push/pull refrigerant recovery 
method is defined as the process of transferring liquid refrigerant from 
a refrigeration system to a receiving vessel by lowering the pressure in 
the vessel and raising the pressure in the system, and by connecting a 
separate line between the system liquid port and the receiving vessel.
    3.6 Recycle Flow Rate. The amount of refrigerant processed divided 
by the time elapsed in the recycling mode. For equipment which uses a 
separate recycling sequence, the recycle rate does not include the 
recovery rate (or elapsed time). For equipment which does not use a 
separate recycling sequence, the recycle rate is a rate based solely on 
the higher of the liquid or vapor recovery rate, by which the 
contaminant levels were measured.
    3.7 Residual Trapped Refrigerant. Refrigerant remaining in equipment 
after clearing refrigerant.
    3.8 Shall, Should, Recommended or It Is Recommended shall be 
interpreted as follows:
    3.8.1 Shall. Where ``shall'' or ``shall not'' is used for a 
provision specified, that provision is mandatory if compliance with this 
appendix is claimed.
    3.8.2 Should, Recommended or It Is Recommended is used to indicate 
provisions which are not mandatory but which are desirable as good 
practice.
    3.9 Standard Contaminated Refrigerant Sample. A mixture of new or 
reclaimed refrigerant and specified quantities of identified 
contaminants which constitute the mixture to be processed by the 
equipment under test. These contaminant levels are expected only from 
severe service conditions.
    3.10 Trapped Refrigerant. The amount of refrigerant remaining in the 
equipment after the recovery or recovery/recycling operation but before 
clearing refrigerant.
    3.11 Vapor Recovery Rate. The average rate that refrigerant is 
withdrawn from the mixing chamber between two pressures as vapor 
recovery rate is changing depending on the pressure. The initial 
condition is vapor only at saturation pressure and temperature at either 
24 [deg]C or at the boiling point at 100 kPa, whichever is higher. The 
final pressure condition is 10 percent of the initial pressure, but not 
lower than the equipment final recovery vacuum and not higher than 100 
kPa.

                Section 4. General Equipment Requirements

    4.1 Equipment Information. The equipment manufacturer shall provide 
operating instructions, necessary maintenance procedures, and source 
information for replacement parts and repair.
    4.2 Filter Replacement. The equipment shall indicate when any

[[Page 200]]

by use of a moisture transducer and indicator light, by use of a sight 
glass/moisture indicator, or by some measurement of the amount of 
refrigerant processed such as a flow meter or hour meter. The equipment 
manufacturer must provide maximum quantity recycled or filter change 
interval in its written instructions.
    4.3 Purge of Non-Condensable. If non-condensables are purged, the 
equipment shall either automatically purge non-condensables or provide 
an indicating means to guide the purge process. Recycling equipment must 
provide purge means.
    4.4 Purge Loss. The total refrigerant loss due to purging non-
condensables, draining oil, and clearing refrigerant (see Section 9.5) 
shall be less than 3 percent (by weight) of total processed refrigerant.

accepted without testing. See Section 7.1.4 of this appendix.
    4.6 Clearing Trapped Refrigerant. For equipment rated for more than 
one refrigerant, the manufacturer shall provide a method and 
instructions which will accomplish connections and clearing within 15 
minutes. Special equipment, other than a vacuum pump or manifold gauge 
set, shall be furnished. The clearing procedure shall not rely upon the 
storage cylinder below saturated pressure conditions at ambient 
temperature.
    4.7 Temperature. The equipment shall be evaluated at 24 [deg]C with 
additional limited evaluation at 40 [deg]C. Normal operating conditions 
range from 10 [deg]C to 40 [deg]C.

                Section 7. Performance Testing Procedures

    7.1 General Testing.
    7.1.1 Temperatures. Testing shall be conducted at an ambient 
temperature of 24 [deg]C  1 [deg]C except high 
temperature vapor recovery shall be at 40 [deg]C  
1 [deg]C. The evaporator conditions of Section 6.2.3 shall be maintained 
as long as liquid refrigerant remains in the mixing chamber.
    7.1.2 Refrigerants. The equipment shall be tested for all designated 
refrigerants (see Section 11.2). All tests in Section 7 shall be 
completed for each refrigerant before starting tests with the next 
refrigerant.
    7.1.3 Selected Tests. Tests shall be as appropriate for the 
equipment type and ratings

[[Page 205]]

parameters selected (see Sections 9.9, 11.1 and 11.2).
    7.1.4 Hose Assemblies. For the purpose of limiting refrigerant 
emissions to the atmosphere, hose assemblies shall be tested for 
permeation according to UL Standard 1963 (incorporated by reference, see 
Sec.82.168).
    7.2 Equipment Preparation and Operation. The equipment shall be 
prepared and operated per the operating instructions.
    7.3 Test Batch. The test batch consisting of refrigerant sample (see 
Section 5) of the test refrigerant shall be prepared and thoroughly 
mixed. Continued mixing or stirring shall be required during the test 
while liquid refrigerant remains in the mixing chamber. The mixing 
chamber shall be filled to 80 percent level by volume.
    7.3.1 Control Test Batch. Prior to starting the test for the first 
batch for each refrigerant, a liquid sample will be drawn from the 
mixing chamber and analyzed per Section 8 to assure that contaminant 
levels match Table 1 within 10 ppm for moisture, 
20 ppm for oleic acid and 0.5 percent for oil.
    7.4 Recovery Tests (Recovery and Recovery/Recycling Equipment)
    7.4.1 Determining Recovery Rates. The liquid and vapor refrigerant 
recovery rates shall be measured during the first test batch for each 
refrigerant (see Sections 9.1, 9.2 and 9.4). Equipment preparation and 
recovery cylinder changeover shall not be included in elapsed time 
measurements for determining vapor recovery rate and liquid refrigerant 
recovery rate. Operations such as subcooling the recovery cylinder shall 
be included. The recovery cylinder shall be the same size as per Section 
6.3 or as furnished by the equipment manufacturer. Oversized tanks shall 
not be permitted.
    7.4.1.1 Liquid Refrigerant Recovery Rate. If elected, the recovery 
rate using the liquid refrigerant feed means (see Section 6.2.5) shall 
be determined. After the equipment reaches stabilized conditions of 
condensing temperature and/or recovery cylinder pressure, the recovery 
process shall be stopped and an initial weight shall be taken of the 
mixing chamber (see Section 9.2). The recovery process shall be 
continued for a period of time sufficient to achieve the accuracy in 
Section 9.4. The recovery process shall be stopped and a final weight of 
the mixing chamber shall be taken.
    7.4.1.2 Vapor Refrigerant Recovery Rate. If elected, the average 
vapor flow rate shall be measured to accuracy requirements in Section 
9.4 under conditions with no liquid refrigerant in the mixing chamber. 
The liquid recovery feed means shall be used. At initial conditions of 
saturated vapor at the higher of 24 [deg]C or the boiling temperature 
(100 kPa), the weight of the mixing chamber and the pressure shall be 
recorded. At final conditions representing pressure in the mixing 
chamber of 10 percent of the initial condition, but not less than the 
final recovery vacuum (see Section 9.6) nor more than 100 kPa, measure 
the weight of the mixing chamber and the elapsed time. At initial 
conditions, the recovery cylinder shall be at saturation pressure at 
ambient conditions.
    7.4.1.3 High Temperature Vapor Recovery Rate. This is applicable for 
equipment having at least one designated refrigerant (see Section 11.2) 
with a boiling point between -50 [deg]C and +10 [deg]C. Measure the rate 
for R-22, or the refrigerant with the lowest boiling point if R-22 is 
not a designated refrigerant. Repeat the test in Section 7.4.1.2 at 
saturated conditions at 40 [deg]C and continue to operate equipment to 
assure it will operate at this condition (see Section 7.4.3). At initial 
conditions, the recovery cylinder shall be at saturated pressure at 40 
[deg]C.
    7.4.1.4 Push/Pull Liquid Refrigerant Recovery Rate. If elected, the 
average liquid push/pull flow rate shall be measured to accuracy 
requirements in Section 9.4. The mixing chamber and filling storage 
cylinder shall be filled with refrigerant vapor at initial conditions of 
saturated vapor at the higher of 24 [deg]C or the boiling temperature at 
100 kPa. An amount of liquid refrigerant shall be added to the mixing 
chamber equivalent to 80 percent by weight of the capacity of the 
filling storage cylinder. The pressure between the mixing chamber and 
filling storage cylinder shall be equalized and stabilized at initial 
conditions of saturated vapor at the higher of 24 [deg]C or the boiling 
temperature at 100 kPa. The initial weight of the mixing chamber and the 
pressure shall be recorded. The equipment is then operated in push/pull 
liquid recovery mode and the weight change of the mixing chamber is 
recorded over time until all of the liquid has been transferred.
    7.4.2 Recovery Operation. This test is for determining the final 
recovery vacuum and the ability to remove contaminants as appropriate. 
If equipment is rated for liquid recovery (see Section 7.4.1.3), liquid 
recovery feed means described in Section 6.2.5 shall be used. If not, 
vapor recovery means described in Sections 6.2.3 or 6.2.4 shall be used. 
Continue recovery operation until all liquid is removed from the test 
apparatus and vapor is removed to the point where equipment shuts down 
by automatic means or is manually shut off per operating instructions.
    7.4.2.1 Oil Draining. Capture oil from the equipment at intervals as 
required in the instructions. Record the weight of the container. 
Completely remove refrigerant from oil by evacuation or other 
appropriate means. The weight difference shall be used in Section 7.5.2.
    7.4.3 Final Recovery Vacuum. At the end of the first test batch for 
each refrigerant, the liquid valve and vapor valve of the apparatus 
shall be closed. After waiting 1 minute, the mixing chamber pressure 
shall be recorded (see Section 9.6).

[[Page 206]]

    7.4.4 Residual Refrigerant. This test will measure the mass of 
remaining refrigerant in the equipment after clearing and therefore the 
extent of mixing different refrigerants (see Section 9.6).
    7.4.4.1 Initial Conditions. At the end of the last test for each 
batch for each refrigerant, the equipment shall be disconnected from the 
test apparatus (Figure 1). Recycle per Section 7.5, if appropriate. 
Perform refrigerant clearing operations as called for in the instruction 
manual. Capture and record the weight of any refrigerant which would 
have been emitted to the atmosphere during the clearing process for use 
in Section 9.5. If two loops are used for recycling, trapped refrigerant 
shall be measured for both.
    7.4.4.2 Residual Trapped Refrigerant. Evacuate an empty test 
cylinder to 1.0 kPa. Record the empty weight of the test cylinder. Open 
all valves to the equipment so as to provide access to all trapped 
refrigerant. Connect the equipment to the test cylinder and operate 
valves to recover the residual refrigerant. Record the weight of the 
test cylinder using a recovery cylinder pressure no less than specified 
in Section 6.2.2. Place the test cylinder in liquid nitrogen for a 
period of 30 minutes or until a vacuum of 1000 microns is reached, 
whichever occurs first.
    7.5 Recycling Tests (Recovery/Recycling Equipment).
    7.5.1 Recycling Operation. As each recovery cylinder is filled in 
Section 7.4.2, recycle according to operating instructions. There will 
not necessarily be a separate recycling sequence. Note non-condensable 
purge measurement in Section 9.5.
    7.5.1.1 Recycle Flow Rate. While recycling the first recovery 
cylinder for each refrigerant, determine the recycling flow rate by 
appropriate means (see Section 9.3) to achieve the accuracy required in 
Section 9.4.
    7.5.2 Non-Condensable Sample. After completing Section 7.4.3, 
prepare a second test batch (see Section 7.3). Recover per Section 7.4.2 
until the current recovery cylinder is filled to 80 percent level by 
volume. Recycle per Section 7.5.1. Mark this cylinder and set aside for 
taking the vapor sample. For equipment having both an internal tank of 
at least 3 kg refrigerant capacity and an external recovery cylinder, 
two recovery cylinders shall be marked and set aside. The first is the 
cylinder described above. The second cylinder is the final recovery 
cylinder after filling it to 80 percent level by volume and recycling.
    7.5.2.1 Push/Pull Liquid Refrigerant Recovery Rate. This rate shall 
be measured by weight change of the mixing chamber divided by elapsed 
time (see Section 7.4.1.4). The units shall be kg/min and the accuracy 
shall be per Section 9.4.
    7.5.3 Liquid Sample for Analysis. Repeat steps in Sections 7.3, 
7.4.2 and 7.5.1 with further test batches until indication means in 
Section 4.2 show the filter/drier(s) need replacing.
    7.5.3.1 Multiple Pass. For equipment with a separate recycling 
circuit (multiple pass), set aside the current cylinder and draw the 
liquid sample (see Section 7.4) from the previous cylinder.
    7.5.3.2 Single Pass. For equipment with the single pass recycling 
circuit, draw the liquid sample (see Section 7.4) from the current 
cylinder.
    7.6 Measuring Refrigerant Loss. Refrigerant loss due to non-
condensables shall be determined by appropriate means (see Section 
9.5.1). The loss could occur in Sections 7.4.1, 7.4.2 and 7.5.1.

            Section 8. Sampling and Chemical Analysis Methods

    8.1 Chemical Analysis. Chemical analysis methods shall be specified 
in appropriate standards such as AHRI Standard 700, 2008 Appendix C for 
Analytical Procedures for AHRI Standard 700-2014- Normative, and 
Addendum 700-1 to Appendix C. If alternate test methods are employed, 
the laboratory must be able to demonstrate that they produce results 
equivalent to the specified referee method.
    8.2 Refrigerant Sampling.
    8.2.1 Moisture Content. The water content in refrigerant shall be 
measured by the Karl Fischer Coulometric Titration technique. Report the 
moisture level in parts per million by weight.
    8.2.2 Chloride Ions. Chloride ions shall be measured by turbidity 
tests. At this time, quantitative results have not been defined. Report 
chloride content as ``pass'' or ``fail.'' In the future, when 
quantitative results are possible, report chloride content as parts per 
million by weight.
    8.2.3 Acid Content. The acidity test uses the titration principle. 
Report the acidity in parts per million by weight (mg KOH/kg) of sample.
    8.2.4 High Boiling Residue. High boiling residues shall use 
measurement of the volume of residue after evaporating a standard volume 
of refrigerant. Using weight measurement and converting to volumetric 
units is acceptable. Report high boiling residues as percent by volume.
    8.2.5 Particulates/Solids. The particulates/solids measurement 
employs visual examination. Report results as ``pass'' or ``fail.''
    8.2.6 Non-condensables. The level of contamination by non-
condensable gases in the base refrigerant being recycled shall be 
determined by gas chromatography. Report results as percent by volume.

             Section 9. Performance Calculations for Ratings

    9.1 Vapor Refrigerant Recovery Rate. This rate shall be measured by 
weight change of

[[Page 207]]

the mixing chamber divided by elapsed time (see 7.4.1.2). The units 
shall be kg/min and the accuracy shall be per Section 9.4.
    9.1.1 High Temperature Vapor Recovery Rate. This rate shall be 
measured by measured weight change of the mixing chamber divided by 
elapsed time (see Section 7.4.1.3). The units shall be kg/min and the 
accuracy shall be per Section 9.4.
    9.2 Liquid Refrigerant Recovery Rate. This rate shall be measured by 
weight change of the mixing chamber divided by elapsed time (see 
7.4.1.3). The units shall be kg/min and the accuracy shall be per 
Section 9.4.
    9.3 Recycle Flow Rate. The recycle flow rate shall be as defined in 
Section 3.12, expressed in kg/min, and the accuracy shall be per Section 
9.4.
    9.3.1 For equipment using multi-pass recycling or a separate 
sequence, the recycle rate shall be determined by dividing the net 
weight, W, of the refrigerant to be recycled by the actual time T 
required to recycle. Any set-up or operator interruptions shall not be 
included in the time T.
    9.3.2 If no separate recycling sequence is used, the recycle rate 
shall be the higher of the vapor refrigerant recovery rate or the liquid 
refrigerant recovery rate. The recycle rate shall match a process which 
leads to contaminant levels in Section 9.9. Specifically, a recovery 
rate determined from bypassing a contaminant removal device cannot be 
used as a recycle rate when the contaminant levels in Section 9.9 are 
determined by passing the refrigerant through the contaminant removal 
device.
    9.4 Accuracy of Flow Rates. The accuracy of test measurements in 
Sections 9.1, 9.2 and 9.3 shall be 008 kg/min for 
flow rates up to 0.42 kg/min and 2.0 percent for 
flow rates larger than 0.42 kg/min. Ratings shall be expressed to the 
nearest 0.02 kg/min.
    9.5 Refrigerant Loss. This calculation will be based upon the net 
loss of refrigerant which would have been eliminated in the non-
condensable purge process (see Section 7.5.1), the oil draining process 
(see Section 7.4.2.1) and the refrigerant clearing process (see Section 
7.4.4.1), all divided by the net refrigerant content of the test 
batches. The refrigerant loss shall not exceed 3 percent by weight.
    9.5.1 Non-Condensable Purge. Evacuate an empty container to 2 kPa. 
Record the empty weight of the container. Place the container in a dry 
ice bath. Connect the equipment purge connection to the container and 
operate purge according to operating instructions so as to capture the 
non-condensables and lost refrigerant. Weigh the cylinder after the 
recycling is complete. Equivalent means are permissible.
    For units which either recycle or publish (list) non-condensable 
removal, non-condensable gases are purged, operating the recycle device 
per the manufacturer's instructions through an evaporator pressure 
regulator (EPR) valve into a liquid nitrogen-chilled cylinder. This 
combination will simulate the atmosphere while allowing the capture of 
purge gases. The cylinder is weighed before and after the purge 
procedure.
    9.5.2 Oil Draining. Refrigerant removed from the oil after draining 
shall be collected and measured in accordance with Section 7.4.2.1.
    9.5.3 Clearing Unit. Refrigerant captured during the clearing 
process shall be measured in accordance with Section 7.4.4.1.
    9.6 Final Recovery Vacuum. The final recovery vacuum shall be the 
mixing chamber pressure in Section 7.4.3 expressed in kPa at 24 [deg]C. 
The accuracy of the measurement shall be within 0.33 kPa.
    9.7 Residual Trapped Refrigerant. The amount of residual trapped 
refrigerant shall be the final weight minus the initial weight of the 
test cylinder in Section 7.4.4.2, expressed in kg. The accuracy shall be 
0.02 kg and reported to the nearest 0.05 kg.
    9.8 Refrigerant Processed. The amount of refrigerant processed 
before changing filters (see Section 7.5.3) shall be expressed in kg to 
an accuracy of 1 percent.
    9.9 Contaminant Levels. The contaminant levels remaining after 
testing shall be published as follows:

Moisture content, ppm by weight
Chloride ions, pass/fail
Acid Content, ppm by weight
High boiling residue, percent (by volume)

    13.1 Particulate Specification
    13.1.1 The particulate material (pm) will be a blend of 50 percent 
coarse air cleaner dust as received, and 50 percent retained on a 200-
mesh screen. The coarse air cleaner

[[Page 209]]

dust is available from: AC Spark Plug Division; General Motors 
Corporation; Flint, Michigan.
    13.1.2 Preparation of Particulate Materials. To prepare the blend of 
contaminant per ANSI/ASHRAE Standard 63.2-1996 (RA 2010), first wet 
screen a quantity of coarse air cleaner dust on a 200-mesh screen 
(particle retention 74 [micro]m). This is done by placing a portion of 
the dust on a 200-mesh screen and running water through the screen while 
stirring the dust with the fingers. The fine contaminant particles 
passing through the screen are discarded. The larger than 200-mesh 
particles collected on the screen are removed and dried for one hour at 
110 [deg]C. The blend of standard contaminant is prepared by mixing 50 
percent by weight of coarse air cleaner dust as received (after drying 
for one hour at 110 [deg]C) with 50 percent by weight of the larger than 
200-mesh screened dust.
    13.1.3 Particle Size Analysis. The coarse air cleaner dust as 
received and the blend used as the standard contaminant have the 
following approximate particle size analysis:

  Sec. Appendix C to Subpart F of Part 82--Method for Testing Recovery 
                  Devices for Use With Small Appliances

 Recovery Efficiency Test Procedure for Refrigerant Recovery Equipment 
                        Used on Small Appliances

    The following test procedure is utilized to evaluate the efficiency 
of equipment designed to recover ozone depleting refrigerants (or any 
substitute refrigerant subject to the recycling rules promulgated 
pursuant to section 608 of the Clean Air Act Amendments of 1990) from 
small appliances when

[[Page 210]]

service of those appliances requires entry into the sealed refrigeration 
system or when those appliances are destined for disposal. This 
procedure is designed to calculate on a weight or mass basis the 
percentage of a known charge of CFC-12 refrigerant removed and captured 
from a test stand refrigeration system. Captured refrigerant is that 
refrigerant delivered to a container suitable for shipment to a 
refrigerant reclaimer plus any refrigerant remaining in the recovery 
system in a manner that it will be transferred to a shipping container 
after additional recovery operations.
    The test stand refrigeration system required for this procedure is 
constructed with standard equipment utilized in currently produced 
household refrigerator and freezer products. The procedure also accounts 
for compressor oils that might be added to or removed from the test 
stand compressor or any compressor used in the recovery system.

                              I. Test Stand

    Test stands are constructed in accordance with the following 
standards.
    1. Evaporator--\5/16\ in. outside dia. with 30 cu. in. volume.
    2. Condenser--\1/4\ in. outside dia. with 20 cu. in volume.
    3. Suction line capillary heat exchanger--appropriate for compressor 
used.
    4. An 800-950 Btu/hr high side case (rotary) compressor; or 
(depending on the test senario);
    5. An 800-9500 Btu/hr low side case (reciprocating) compressor.
    A person seeking to have its recovery system certified shall specify 
the compressors by manufacturer and model that are to be used in test 
stands constructed for evaluation of its equipment, and the type and 
quantity of compressor to be used in those compressors. Only a 
compressor oil approved for use by the compressor's manufacturer may be 
specified, and the quantity of compressor oil specified shall be an 
appropriate quantity for the type of oil and compressor to be used. In 
order to reduce the cost of testing, the person seeking certification of 
its recovery system may supply an EPA approved third party testing 
laboratory with test stands meeting these standards for use in 
evaluating its recovery system.

                           II. Test Conditions

    Tests are to be conducted at 75 degrees F, plus or minus 2 degrees F 
(23.9 C 1.1 C). Separate tests are conducted on 
both high side case compressor stands and low side case compressor 
stands. Separate tests are also conducted with the test stand compressor 
running during the recovery operation, and without the test stand 
compressor running during the recovery operation, to calculate the 
system's recovery efficiency under either condition.
    These tests are to be performed using a representative model of all 
equipment used in the recovery system to deliver recovered refrigerant 
to a container suitable for shipment to a refrigerant reclaimer. The 
test stands are to be equipped with access valves permanently installed 
as specific by the recovery system's vendor to represent the valves used 
with that system in actual field operations.
    A series of five (5) recovery operations are to be performed for 
each compressor scenario and a recovery efficiency is calculated based 
on the total quantity of refrigerant captured during all five (5) 
recoveries. Alternatively, at the request of the recovery system's 
vendor, a recovery efficiency is to be calculated for each recovery 
event. In this case, a statistically significant number of recovery 
operations are to be performed. Determination of what is a statistically 
significant number of recoveries is to be calculated as set out below. 
These individual recovery efficiencies are then averaged.
    There are four (4) compressor scenarios to be tested. These are a 
high side case compressor in working condition; a high side case 
compressor in nonworking condition; a low side case compressor in 
working condition; and a low side case compressor in nonworking 
condition. Recovery efficiencies calculated for the two working 
compressor scenarios are to be averaged to report a working compressor 
performance. The two nonworking compressor efficiencies are also to be 
averaged to report a nonworking compressor performance.
    If large scale equipment is required in the system to deliver 
recovered refrigerant to a refrigerant reclaimer (eg. carbon desorption 
equipment) and it is not possible to have that equipment evaluated under 
the procedure, the system's vendor shall obtain engineering data on the 
performance of that large scale equipment that will reasonably 
demonstrate the percentage refrigerant lost when processed by that 
equipment. That data will be supplied to any person required to evaluate 
the performance of those systems. The following procedure will also be 
modified as needed to determine the weight of refrigerant recovered from 
a test stand and delivered to a container for shipment to the large 
process equipment for further processing. The percentage loss documented 
to occur during processing is then to be applied to the recovery 
efficiencies calculated in this modified procedure to determine the 
overall capture efficiency for the entire system.
    The following are definitions of symbols used in the test procedure.

Test Stand:
    ``TSO'' means an original test stand weight.
    ``TSC'' means a charged test stand weight.

[[Page 211]]

Shipping Containers:
    ``SCO'' means the original or empty weight of shipping container(s).
    ``SCF'' means the final or full weight of shipping container(s).
Recover/Transfer System:
    ``RSO'' means the original weight of a recovery/transfer system.
    ``RSF'' means the final weight of a recovery/transfer system.
    ``OL'' means the net amount of oil added/removed from the recovery 
device and/or transfer device between the beginning and end of the test 
for one compressor scenario.
Weighing steps are conducted with precision and accuracy of plus or 
          minus 1.0 gram.

                           III. Test Procedure

    1. Evacuate the test stand to 20 microns vacuum (pressure measured 
at a vacuum pump) for 12 hours.
    2. Weigh the test stand (TSO).
    3. If this is the first recovery operation being performed for a 
compressor scenario (or if a recovery efficiency is to be calculated for 
each recovery event), then weigh all devices used in the recovery system 
to deliver recovered refrigerant to a container suitable for shipment or 
delivery to a refrigerant reclaimer. Weigh only devices that can retain 
refrigerant in a manner that it will ultimately be transferred to a 
shipping container without significant release to the atmosphere (RSO).
    4. Weigh final shipping containers (SCO).
    5. Charge the test stand with an appropriate CFC-12 charge (either 6 
oz. or 9 oz.).
    6. Run the test stand for four (4) hours with 100% run time.
    7. Turn off the test stand for twelve (12) hours. During this period 
evaporate all condensation that has collected on the test stand during 
step 6.
    8. Weigh the test stand (TSC).
    9. Recover CFC-12 from the test stand and perform all operations 
needed to transfer the recovered refrigerant to one of the shipping 
containers weighed in step 4. All recovery and transfer operations are 
to be performed in accordance with the operating instructions provided 
by the system's vendor. The compressor in the test stand is to remain 
``off'' or be turned ``on'' during the recovery operation depending on 
whether the test is for a nonworking or working compressor performance 
evaluation. If a recovery efficiency is to be calculated for each 
recovery event, transfer the captured refrigerant to a shipping 
container and then skip to step 13. Otherwise continue. If the system 
allows for multiple recovery operations to be performed before 
transferring recovered refrigerant to a shipping container, the transfer 
operation can be delayed until either the maximum number of recovery 
operations allowed before a transfer is required have been performed, or 
the last of the five (5) recovery operations has been performed.
    10. Perform any oil removal or oil addition operations needed to 
properly maintain the test stand and the devices used for recovery or 
transfer operations. Determine the net weight of the oil added or 
removed from the recovery device and/or transfer device. (OP1 for oil 
added, OP2 for oil removed).
    11. Evacuate the test stand to 20 microns vacuum for 4 hours.
    12. Return to step 2 unless five (5) recovery operations have been 
performed.
    13. Weigh all final shipping containers that received recovered 
refrigerant (SCF).
    14. Weigh the equipment weighed in step three (3) above (RSF). If a 
recovery efficiency is to be calculated for each recovery event, perform 
calculations and return to step one (1) for additional recoveries.

                            IV. Calculations

                 A. For Five (5) Consecutive Recoveries

    Refrigerant Recoverable equals the summation of charged test stand 
weights minus original test stand weights.


    Oil Loss equals the net weight of oil added to and removed from the 
recovery device and/or transfer device.

[[Page 212]]



    Refrigerant Recovered equals the final weight of shipping containers 
minus the initial weight of final shipping containers, plus final 
recovery system weight, minus original recovery system weight, plus the 
net value of all additions and removals of oil from the recovery and 
transfer devices.
[GRAPHIC] [TIFF OMITTED] TN30AU93.001

    n = number of shipping containers used.

    Recovery Efficiency equals Refrigerant Recovered divided by 
Refrigerant Recoverable times 100%.
[GRAPHIC] [TIFF OMITTED] TN30AU93.002

                      B. For Individual Recoveries

    Refrigerant Recoverable equals the charged test stand weight minus 
the original test stand weight.
[GRAPHIC] [TIFF OMITTED] TN30AU93.003

    Refrigerant Recovered equals the final weight of the shipping 
container minus the initial weight of the shipping container plus the 
final weight of the recovery system minus the original recovery system 
weight.
[GRAPHIC] [TIFF OMITTED] TN30AU93.004

    Recovery Efficiency equals Refrigerant Recovered divided by 
Refrigerant Recoverable times 100 percent.

Procedure:
    1. Compute Nadd after completing two recoveries.
    2. If Nadd0, then run an additional test.
    3. Re-compute Nadd. Continue to test additional samples 
until Nadd<0.

              V. Test Procedure Approval and Certification

    Each vendor of capture equipment for small appliances desiring 
certification will provide a representative model of its capture system 
and its recommended recovery procedures to an EPA approved third party 
laboratory for testing in accordance with this procedure. The third 
party laboratory will certify recovery systems that when tested in 
accordance with this procedure demonstrate a sufficient recovery 
efficiency to meet EPA regulatory requirements.



   Sec. Appendix D to Subpart F of Part 82--Standards for Becoming a 
                   Certifying Program for Technicians

    a. Test Preparation. Technicians must pass an EPA-approved test, 
provided by an EPA-approved certifying program to be certified as a Type 
I technician. Organizations providing Type I certification only may 
choose either an on-site format or a mail-in format similar to what is 
permitted under the MVACs program.
    Technicians must pass a closed-book, proctored test, administered in 
a secure environment, by an EPA-approved certifying program to be 
certified as a Type II or Type III technician.
    Technicians must pass a closed-book, proctored test (or series of 
tests), administered in a secure environment, by an EPA-approved 
certifying program to be certified as a Universal technician. Mail-in 
format Type I tests cannot be used toward a Universal certification.
    Each certifying program must assemble tests by choosing a prescribed 
subset from the EPA test bank. EPA will have a test bank with more 
questions than are needed for an individual test, which will enable the 
certifying program to generate multiple tests in order to discourage 
cheating. Each test must include 25 questions drawn from Group 1 and 25 
questions drawn from each relevant technical Group. Tests for Universal 
technicians will include 100 questions (25 from Group 1 and 25 from each 
relevant technical Group). Universal tests may be taken all at once, or 
by combining passing scores on separate Type I, Type II, and Type III 
tests. Questions should be divided in order to sufficiently cover each 
topic within the Group.
    Certifying programs must provide a paper hand-out or electronic form 
of communication to technicians after they have completed their 
certification test that contains the following information:

--Which certifying program is providing the testing;
--Contact information for the certifying program;
--The name and contact information of the proctor; and
--When they should expect to receive their score and, if they passed, 
their certification card.

    Each certifying program must show a method of randomly choosing 
which questions will be on the tests. Multiple versions of the test must 
be used during each testing event. Test answer sheets must include the 
name and address of the applicant, the name and address of the 
certifying program, and the date and location at which the test was 
administered.
    Training material accompanying mail-in Type I tests must not include 
sample test questions mimicking the language of the certification test. 
All mail-in material will be subject to review by EPA.
    Certifying programs may charge individuals reasonable fees for the 
administration of the tests. EPA will publish a list of all approved 
certifying programs.

[[Page 214]]

    b. Proctoring. A certifying program for Type I (if in-person), Type 
II, Type III, and Universal technicians must designate at least one 
proctor registered for every 50 people taking tests at the same time at 
a given site.
    The certification test for Type I (if taken as part of a Universal 
certification), Type II, Type III, and Universal technicians is a 
closed-book exam. The proctors must ensure that the applicants for 
certification do not use any notes or training materials during testing. 
Desks or work space must be placed in a way that discourages cheating. 
The space and physical facilities are to be conducive to continuous 
surveillance by the proctors and monitors during testing.
    The proctor may not receive any benefit from the outcome of the 
testing other than a fee for proctoring. Proctors cannot know in advance 
which questions are on the tests they are proctoring.
    Proctors are required to verify the identity of individuals taking 
the test by examining photo identification. Acceptable forms of 
identification include but are not limited to drivers' licenses, 
government identification cards, passports, and military identification.
    Certifying programs for Type I technicians using the mail-in format, 
must take sufficient measures at the test site to ensure that tests are 
completed honestly by each technician. Each test for Type I 
certification must provide a means of verifying the identification of 
the individual taking the test. Acceptable forms of identification 
include but are not limited to drivers' licenses and passports.
    c. Test Security. A certifying program must demonstrate the ability 
to ensure the confidentiality and security of the test questions and 
answer keys through strict accountability procedures. An organization 
interested in developing a technician certification program will be 
required to describe these test security procedures to EPA.
    After the completion of a test, proctors must collect all test 
forms, answer sheets, scratch paper and notes. These items are to be 
placed in a sealed envelope.
    d. Test Content. All Type I, Type II and Type III, certification 
tests will include 25 questions from Group I and 25 questions from Group 
II. Universal certification tests will include 25 questions from Group I 
and 75 questions from Group II (with 25 from each of the three sector-
specific areas).
    Group I will ask questions in the following areas:

1. Environmental impact of CFCs, HCFCs, and substitute refrigerants
2. Laws and regulations
3. Changing industry outlook

    Group II will ask questions covering sector-specific (i.e., Type I, 
Type II, Type III) issues in the following areas:

4. Leak detection
5. Recovery Techniques
6. Safety
7. Shipping
8. Disposal

    e. Grading. Tests must be graded objectively. Certifying programs 
must inform the applicant of their test results no later than 30 days 
from the date of the test. Type I certifying programs using the mail-in 
format must notify the applicants of their test results no later than 30 
days from the date the certifying programs received the completed test 
and any required documentation.
    The passing score for the closed-book Type I, Type II, Type III and 
Universal certification test is 70 percent. The passing score for Type I 
certification tests using the mail-in format is 84 percent.
    f. Proof of Certification. Certifying programs must issue a standard 
wallet-sized identification card no later than 30 days from the date of 
the test. Type I certifying programs using mail-in formats must issue 
cards to certified technicians no later than 30 days from the date the 
certifying program receives the completed test and any required 
documentation.
    Each wallet-sized identification card must include, at a minimum, 
the name of the certifying program including the date the certifying 
program received EPA approval, the name of the person certified, the 
type of certification, a unique number for the certified person that 
does not include a technician's social security number, and the 
following text:

    [name of person] has successfully passed a [Type I, Type II, Type 
III and/or Universal--as appropriate] exam on how to responsibly handle 
refrigerants as required by EPA's National Recycling and Emissions 
Reduction Program.

    g. Recordkeeping and Reporting Requirements. Certifying programs 
must maintain records of the names and addresses of all individuals 
taking the tests, the scores of all certification tests administered, 
and the dates and locations of all tests administered. These records 
must be maintained indefinitely, unless transferred to another 
certifying program or EPA.
    EPA must receive an activity report from all approved certifying 
programs by every January 30 and July 30, which covers the previous six 
months of certifications. The first report must be submitted following 
the first full six-month period for which the program has been approved 
by EPA. This report includes the pass/fail rate. If the certifying 
program believes a test bank question needs to be modified, information 
about that question should also be included.
    Approved certifying programs will receive a letter of approval from 
EPA. Each testing

[[Page 215]]

center must display a copy of that letter at their place of business.
    Approved technician certification programs that voluntarily plan to 
stop providing the certification test must forward all records required 
by this appendix and Sec.82.161 to another program currently approved 
by EPA in accordance with this appendix and with Sec.82.161. Approved 
technician certification programs that receive records of certified 
technicians from a program that no longer offers the certification test, 
and the program that is voluntarily withdrawing from being a technician 
certification program must inform EPA at the address listed in Sec.
82.160 within 30 days of receiving or transferring these records. The 
notification must include the name and address of the program to which 
the records have been transferred. If another currently approved program 
willing to accept the records cannot be located, these records must be 
submitted to EPA at the address listed at Sec.82.160.
    Technician certification programs that have had their certification 
revoked in accordance with Sec.82.169 must forward all records 
required by this appendix and Sec.82.161 to EPA at the address listed 
in Sec.82.160. Failure to do so is a violation of 40 CFR part 82, 
subpart F.
    h. Additional Requirements. EPA may periodically inspect testing 
sites to ensure compliance with EPA regulations. If testing center 
discrepancies are found, they must be corrected within a specified time 
period. If discrepancies are not corrected, EPA may suspend or revoke 
the certifying program's approval. The inspections will include but are 
not limited to a review of the certifying program's provisions for test 
security, the availability of space and facilities to conduct the 
administrative requirements and ensure the security of the tests, the 
availability of adequate testing facilities and spacing of the 
applicants during testing, a review of the proper procedures regarding 
accountability, and that there is no evidence of misconduct on the part 
of the certifying programs, their representatives and proctors, or the 
applicants for certification.
    If the certifying programs offer training or provide review 
materials to the applicants, these endeavors are to be considered 
completely separate from the administration of the certification test.

[81 FR 82390, Nov. 18, 2016]



 Sec. Appendix E to Subpart F of Part 82--Test Procedure for Leaks From 
 Containers Holding Two Pounds or Less of Refrigerant for Use in an MVAC

    This appendix is based on the California Air Resources Board (CARB) 
standard TP-503: Test Procedure for Leaks from Small Cans of Automotive 
Refrigerant, as amended on January 5, 2010; and CARB standard BP-A1: 
Balance Protocol for Gravimetric Determination of Sample Weights using a 
Precision Balance, as amended January 5, 2010.

                        Section 1. Applicability

    This test procedure is used by manufacturers of containers holding 
two pounds or less of refrigerant for use in a motor vehicle air 
conditioner (MVAC) to determine the leakage rate of small containers of 
automotive refrigerant that are subject to the requirements of 40 CFR 
part 82, subpart F. Specifically, this test procedure will specify the 
equipment, procedures, and calculations to determine if a container 
holding two pounds or less of refrigerant for use in an MVAC complies 
with the leakage rate specified in Sec.82.154(c)(2)(ii). All terms in 
this appendix will follow the definitions in Sec.82.152 unless 
otherwise defined in this appendix.
    All containers holding two pounds or less of refrigerant for use in 
an MVAC must comply with other applicable codes and regulations such as 
local, state, or Federal safety codes and regulations.
    This test procedure involves the use of materials under pressure and 
operations and should only be used by or under the supervision of those 
familiar and experienced in the use of such materials and operations. 
Appropriate safety precautions should be observed at all times while 
performing this test procedure.

           Section 2. Principle and Summary of Test Procedure

    This procedure is used to determine the leakage rate of containers 
holding two pounds or less of refrigerant for use in an MVAC (small 
cans). Testing will involve subjecting both full and partially empty 
cans in both upright and inverted positions at two temperatures: 73 
[deg]F and 130 [deg]F.
    Thirty small cans are tested under each condition for a total of 240 
small cans tested. Small cans are brought to temperature stability, 
weighed, then stored for 30 days under specified conditions of 
temperature, orientation, and state of fill, then re-weighed. Leakage 
rate (grams/year) is estimated by (weight loss in grams) x 365/(days 
duration). The leakage rate is then compared to a standard of 3.00 
grams/year to determine if a given small can complies with the leakage 
rate specified in Sec.82.154(c)(2)(ii).

                   Section 3. Biases and Interferences

    3.1 Contaminants on the operator's hands can affect the weight of 
the small can and the ability of the small can to absorb moisture. To 
avoid contamination of the small can, the balance operator should wear 
gloves while handling the small cans.

[[Page 216]]

    3.2 Weight determinations can be interfered with by moisture 
condensing on the small can and by thermal currents generated by 
temperature differences between the small can and the room temperature. 
The small cans cool during discharge and could cause condensation. For 
these reasons, small cans must be equilibrated to balance room 
temperature for at least four hours before weighing.
    3.3 Variations in the temperature, pressure, and humidity of the 
ambient air will cause variations in the buoyancy of the small can. 
These variations should typically be less than 25 mg for a small can. If 
the small can is not leaking at all, then the uncorrected weight changes 
will be within the range of 0  25 mg, which is 
about ten percent of the 247 mg loss expected after thirty days for a 
can leaking at 3 g/yr. In that case buoyancy corrections can be omitted. 
If the absolute value of the uncorrected weight change exceeds 25 mg, 
then all calculations must be made using weights corrected for buoyancy 
based on the temperature, pressure, and humidity of the weighing room.
    3.4 Some electronic balances are sensitive to the effects of small 
static charges. The small can should be placed directly on the balance 
pan, ensuring metal to metal contact. If the balance pan is not 
grounded, the small can and balance pan should be statically discharged 
before weighing.

                    Section 4. Sensitivity and Range

    The mass of a full small can could range from roughly 50 g to 1000 g 
depending on the container capacity. A top loading balance, capable of a 
maximum weight measurement of not less than 1,000 g and having a minimum 
readability of 0.001 g, reproducibility and linearity of  0.002 g, must be used to perform mass measurements.

                          Section 5. Equipment

    5.1 A top loading balance that meets the requirements of Section 4 
above.
    5.2 A NIST traceable working standard mass for balance calibration. 
A NIST traceable working standard mass for a balance linearity check. A 
reference mass to serve as a ``blank'' small can.
    5.3 An enclosure capable of controlling the internal air temperature 
from 73 [deg]F  5 [deg]F, and an enclosure capable 
of controlling the internal air temperature to 130 [deg]F  5 [deg]F.
    5.4 A temperature instrument capable of measuring the internal 
temperature of the temperature conditioning enclosures and the balance 
room with a sensitivity of  2 [deg]F.
    5.5 A barometric pressure instrument capable of measuring 
atmospheric pressure at the location of the balance to within  0.02 inches of mercury.
    5.6 A relative humidity measuring instrument capable of measuring 
the relative humidity (RH) at the location of the balance with a 
sensitivity of  2 percent RH.
    5.7 A hose with appropriate fitting for dispensing refrigerant from 
the small can to a recovery machine.
    5.8 A refrigerant recovery machine to collect the discharged 
refrigerant from small cans being tested.

                    Section 6. Calibration Procedures

    6.1 Calibrations are applied to the balance and to the support 
equipment such as temperature, humidity, and pressure monitoring 
equipment. Procedures for calibration are not spelled out here. General 
calibration principals for the support equipment and the balance are 
described in Section 11, Quality Assurance/Quality Control. Detailed 
calibration procedures for measurements made using the balance are 
contained in Attachment A: ``Balance Protocol for Gravimetric 
Determination of Sample Weights using a Precision Balance.''

                    Section 7. Small Can Preparation

    7.1 Receive a batch of 240 small cans of one design to be tested. 
These may include several SKUs from different manufacturers if the 
container and valve combination are the same.
    7.2 Clean small cans with Alkanox solution or equivalent and dry 
with a lint free towel.
    7.3 Confirm that the sample ID sticker on the small can matches the 
sample ID on the chain of custody forms.
    7.4 Select a reference mass similar to the weight of a full small 
can. If multiple sets of similar sized small cans are being tested, only 
one reference mass is needed; it can be used with all sets. Store the 
reference mass in the balance area.
    7.5 Evacuate the contents of one half of the small cans (120 cans) 
into the refrigerant recovery machine using normal DIY dispensing 
procedures until each small can is approximately half full.
    7.6 Select a reference mass similar to the weight of the half-full 
small can. If multiple sets of similar size small cans are being tested, 
only one reference mass is needed; it can be used with all sets. Store 
the reference mass in the balance area.

                      Section 8. Small Can Weighing

    Weighing cans on the balance is done in accordance with Attachment A 
to this appendix. Attachment A describes how to conduct weight 
determinations including appropriate calibration and QC data. This 
section, ``Small Can Weighing,'' describes the overall process, not the 
details of how to use the balance.

[[Page 217]]

                             Initial Weights

    8.1 Put on gloves. Check the small cans for contamination.
    8.2 Place the 240 small cans into a location where they can 
equilibrate to balance room temperature. Record the small can test IDs 
and the equilibration start time on the Small Can Test Data Forms 
available on EPA's Web site in sets of thirty, one form for each of the 
eight test conditions.
    8.3 Let cans equilibrate for at least four hours.
    8.4 Weigh the set of 240 small cans and the reference weights using 
Attachment A and log the results to the Balance Weighing Log Form 
available on EPA's Web site.
    8.5 Transfer data from the Balance Weighing Log Form to the Small 
Can Test Data Form in sets of 30, one set for each of the eight 
conditions to be tested.

                             Thirty-Day Soak

    8.6 Place each set of 30 small cans into the appropriate orientation 
and temperature for soaking:

30 full small cans--73 [deg]F, upright
30 full small cans--73 [deg]F, inverted
30 full small cans--130 [deg]F, upright
30 full small cans--130 [deg]F, inverted
30 half-full small cans--73 [deg]F, upright
30 half-full small cans--73 [deg]F, inverted
30 half-full small cans--130 [deg]F, upright
30 half-full small cans--130 [deg]F, inverted

    8.7 Soak the small cans for 30 days undisturbed.

                             Final Weighing

    8.8 Place the 240 small cans into a location where they can 
equilibrate to balance room temperature.
    8.9 Let the small cans equilibrate for at least four hours.
    8.10 Weigh the set of 240 small cans, the reference weights, and any 
additional sets of small cans using Attachment A.
    8.11 Transfer data from the Balance Weighing Log Form to the 
corresponding Small Can Test Data Forms.

                         Section 9. Calculations

                        Corrections for Buoyancy

    The calculations in this section are described in terms of 
``weight.'' Mass is a property of the small can, whereas weight is a 
force due to the effects of buoyancy and gravity. Procedures for 
correcting the effect of buoyancy are given in Attachment B of this 
appendix. Ignoring buoyancy, i.e., using weight data uncorrected for 
buoyancy effects, is acceptable for a thirty day test if the absolute 
magnitude of the weight change is less than 25 mg. If the uncorrected 
weight change exceeds 25 mg for any small can, then correct all small 
can weights for buoyancy using the procedures in Attachment B before 
performing the calculations described below.

                        Calculation of Leak Rate

    The emission rate in grams/day for each small can is calculated by 
subtracting the final weight from the initial weight and then dividing 
the weight difference by the time difference measured in days to the 
nearest hour (nearest 1/24 of a day). The emission rate in g/day is 
multiplied by 365 to determine emission rate in grams/yr. If the annual 
emission rate for any small can exceeds the entire small can contents, 
then the annual emission rate for that small can is adjusted to equal 
the entire small can contents/year (e.g., about 350 g/yr for a 12 ounce 
small can). The annual emission rate for the purpose of the test is 
calculated by averaging the 240 individual adjusted annual emission 
rates and rounding to two decimal places. The cans fail the test if the 
adjusted annual emission rate averaged over 240 cans is greater than 
3.00 g/yr. The calculations are described below.
    Loss rate for each small can

Eidaily = (Wifinal - Wiinitial)/
          (Difinal - Diinitial) g/day
Eiannual = 365 x Eidaily g/year
Eiadjusted = Minimum of (Eiadjusted, Ci/year) g/yr

Where,

Ei = emission rate
Wifinal = weight of can i after soaking (grams)
Wiinitial = weight of can I before soaking (grams)
Difinal = date/time of final weight measurements (days)
Diinitial = date/time of initial weight measurements (days)
Ci = original factory mass of refrigerant in can i

    Note: Date/Times are measured in days. Microsoft Excel stores dates 
and times in days, and the calculations can be made directly in Excel. 
If calculations are made manually, calculate serial days to the nearest 
hour for each date and time as follows:

D = Julday + Hour/24

Where,

Julday = serial day of the year: Jan 1 = 1, Jan 31 = 31, Feb 1 = 32, 
          etc.
Hour = hour of day using 24-hour clock, 0 to 23

    Calculate the average loss rate for the 240 small cans as follows:

Emean = [Sum (Eadjustedi), i = 1 to 240]/240

                        Section 10. Recordkeeping

    During small can weighing, record the small can weights and date/
times on the Balance Weighing Log Form. After each weighing session, 
transfer the measured weights and date/times from the Balance Weighing 
Log Form to the Small Can Test Data Form.

[[Page 218]]

    At the end of the test, complete the calculations described in 
Section 9, Calculations, and record the results on the Small Can Test 
Data Form.

              Section 11. Quality Assurance/Quality Control

    11.1 All temperature, pressure, and humidity instruments should be 
calibrated annually against NIST traceable laboratory standards. The 
main purpose of the NIST traceable calibration is to establish the 
absolute accuracy of the device. The instruments should also be checked 
periodically such as weekly, monthly, or quarterly against intermediate 
standards or against independent instruments. For example, a 
thermocouple can be checked weekly against a wall thermometer. A 
barometer or pressure gauge can be checked weekly by adjusting to sea 
level and comparing with local airport data. The main purpose of the 
frequent checks is to verify that the device has not failed in some way. 
This is especially important for electronic devices such as a digital 
thermometer, but even a liquid filled thermometer can develop a problem 
such as a bubble.
    11.2 The balance should be serviced and calibrated annually by an 
independent balance service company or agency using NIST traceable 
reference masses. Servicing verifies accuracy and linearity, and the 
maintenance performed helps ensure that a malfunction does not develop.
    11.3 The balance must also be calibrated and its linearity checked 
with working standards before and after each weighing session, or before 
and after each group of 24 small cans if more than 24 small cans are 
weighed in a session. Procedures for calibrating and using the balance, 
as well as recording balance data, are described in the accompanying 
balance weighing protocol. These procedures include zero checks, 
calibration checks, and reference mass checks. Procedures for 
calculating quality control data from those checks are described in 
Attachment A.
    11.4 The small cans are cleaned then handled using gloves to prevent 
contamination. All equilibration and soaking must be done in a dust free 
area.

  Section 12. Balance Protocol for Gravimetric Determination of Sample 
                    Weights Using a Precision Balance

    12.1 Scope and application
    This Protocol summarizes a set of procedures and tolerances for 
weighing objects in the range of 0 to 1,000 g with a resolution of 0.001 
g. This protocol only addresses balance operations, it does not address 
project requirements for equilibration, sample hold time limits, sample 
collection etc.
    12.2 Summary of method
    The balance is zeroed and calibrated using procedures defined 
herein. Object weight determinations are conducted along with control 
object weight determinations, zero checks, calibration checks, 
sensitivity checks, and replicate weightings in a defined sequence 
designed to control and quantitatively characterize precision and 
accuracy.
    12.3 Definitions
    N/A.
    12.4 Interferences
    Object weights can be affected by temperature and relative humidity 
of their environment, air currents, static electricity, gain and loss of 
water vapor, gain or loss of and loss of volatile compounds directly 
from the sample or from contaminants such as finger prints, marker ink, 
and adhesive tape.
    Contamination, transfer of material to or from the samples, is 
controlled by conducting operations inside a clean area dedicated to the 
purpose and having a filtered laminar air flow where possible; by 
wearing gloves while handling all samples and related balance equipment; 
by using forceps to handle small objects, and by keeping the balance and 
all related equipment inside the clean area.
    Air currents are controlled by conducting weighing operations inside 
a closed chamber or glove box and by allowing the substrates to reach 
temperature and relative humidity equilibrium. The chamber is maintained 
at 40 percent relative humidity and 25 [deg]C by a continuous humidity 
and temperature control system. The temperature and RH conditions are 
recorded at least once per weighing sessions. Equilibration times for 
samples that are particularly sensitive to humidity or to loss of semi-
volatiles species are specified by project requirements.
    Static electric charges on the walls of the balance and the weighed 
objects, including samples, controls, and calibration weights, can 
significantly affect balance readings. Static is avoided by the operator 
ground himself and test objects as described in the balance manual.

    12.8 Sample collection, preservation, and storage
    N/A. See relevant project requirements and SOPs.
    12.9 Quality control
    Data quality is controlled by specifying frequencies and tolerances 
for Zero, Calibration, Linearity, and Sensitivity checks. If checks do 
not meet tolerance criteria, then samples must be re-weighed. In 
addition, the procedures specify frequencies for Control Object Checks.
    Data quality is quantitatively characterized using Zero Check, 
Calibration Check, and Control Check data. These data are summarized 
monthly in statistics and QC charts.
    12.10 Calibration and standardization
    The absolute accuracy of the balance is established by calibration 
against an ANSI Class 2, stainless steel working weight: 1000.000 g 
 0.0025 g. Linearity is established checking the 
midpoint against an ANSI Class 2 stainless steel working weight: 500.000 
 0.0012 g. Sensitivity is established using and 
ANSI Class 2 stainless steel or aluminum working weight: 50 mg. 
Precision is checked by periodically checking zero, calibration, and 
reference object weights.
    12.11 Procedure
    12.11.1 Overview of Weighing Sequence
    Weighing a series of substrates consists of performing the following 
procedures in sequence, while observing the procedures for handling and 
the procedures for reading the balance:

1. Initial Adjustment
2. Weigh eight samples
3. Zero Check
4. Weigh eight samples
5. Zero Check
6. Weigh eight samples
7. Calibration Check
8. Return to step 2.
9. If less than 24 cans are weighed, perform a final Calibration Check 
          at the end of weighing.

    This sequence is interrupted and samples are reweighed if QC check 
tolerances are not met. Each of these procedures along with procedures 
for handling and reading the balance are described below. The QC 
tolerances referred to in these procedures are listed in Table 1.
    12.11.2 Handling
    1. Never touch samples, weights, balance pans, etc. with bare hands. 
Wear powder free gloves to handle the weights, controls, and samples.
    12.11.3 Reading the Balance
    1. Close the door. Wait for the balance stabilization light to come 
on, and note the reading.
    2. Watch the balance reading for 30 sec (use a clock). If the 
reading has not changed by more than 0.001 g from the reading noted in 
step 1, then record the reading observed at the end of the 30 sec 
period.
    3. If the reading has drifted more than 0.001 g note the new balance 
reading and go to step 2.
    4. If the balance reading is flickering back and forth between two 
consecutive values choose the value that is displayed more often than 
the other.
    5. If the balance reading is flickering equally back and forth 
between two consecutive values choose the higher value.
    12.11.4 Initial Adjustment

1. Empty the sample pan Close the door. Select Range 1000 g
2. Wait for a stable reading
3. Record the reading with QC code IZC (initial zero check)
4. Press the Tare button
5. Record the reading in the logbook with QC code IZA (initial zero 
          adjust)
6. Place the 1,000 g working calibration weight on the balance pan
7. Wait for a stable reading.
8. Record the reading with QC code ICC (initial cal check)
9. Press the Calibrate button
10. Record the reading with QC code ICA (initial cal adjust)
11. Remove the calibration weight.
12. Wait for a stable reading.
13. Record the reading with QC code IZC.
14. If the zero reading exceeds  0.002 g, go to 
          step 4.
15. Place the 500 g calibration weight on the balance pan
16. After a stable reading, record the reading with QC code C500. Do not 
          adjust the balance.
17. Add the 0.050 g weight to 500 g weight on the balance pan.
18. After a stable reading, record the reading with QC code C0.05. Do 
          not adjust the balance.
19. Weigh reference object TEST1, record reading with QC code T1.
20. Weigh the reference object TEST2, TEST3, etc. that is similar in 
          weight to the samples that you will be weighing. Record with 
          QC code T2, T3, etc.

    12.11.5 Zero Check

1. Empty the sample pan. Close the door.
2. Wait for a stable reading
3. Record the reading with QC code ZC
4. If the ZC reading is less than or equal to the zero adjustment 
          tolerance shown in Table 1, return to weighing and do not 
          adjust the zero. If the ZC reading exceeded the zero 
          adjustment tolerance, proceed with steps 5 through 7.
5. Press the Tare button
6. Record the reading in the logbook with QC code ZA.
7. If the ZC reading exceeded the zero re-weigh tolerance, change the QC 
          code recorded in step 3 from ZC to FZC. Then

[[Page 220]]

          enter a QC code of FZ into the QC code column of all samples 
          weights obtained after the last valid zero check. Re- weigh 
          all of those samples, recording new data in new rows of the 
          logbook.

    12.11.6 Calibration Check

1. First, follow procedures for Zero Check. If the ZC was within 
          tolerance, tare the balance anyway (i.e., follow steps 5 and 6 
          of the Zero Check method)
2. Place the 1,000 g working calibration weight on the sample pan, wait 
          for a stable reading.
3. Record the reading with QC code C1000
4. If the C1000 reading is less than or equal to the calibration 
          adjustment tolerances, skip steps 5 through 8 and proceed to 
          step 9. Do not adjust the calibration.
5. If the C100 reading exceeded the calibration adjust tolerance, press 
          the Calibrate button.
6. Record the reading in the logbook with QC code CA
7. Perform a Zero Check (follow the Zero Check method)
8. If the C1000 reading exceeded the calibration re-weigh tolerance, 
          change the code recorded in step 3 from C1000 to FC1000. Enter 
          FC into the QC column for all sample weights obtained after 
          the last valid calibration check. Re-weigh all of those 
          samples, recording new data in new rows of the logbook.

    12.11.7 Replicate Weighing Check
    1. This protocol does not include reweigh samples to obtain 
replicates. The projects for which this protocol is intended already 
include procedures multiple weightings of each sample.

------------------------------------------------------------------------

    12.12 Data analysis and calculations
    For Zero Checks, let Z equal the recorded Zero Check value. For 
control checks let T1, T2, etc. equal the recorded value for control 
object Test 1, Test 2, etc. For Calibration Checks, let C1000 equal 
C1000 reading minus 1000, M = C500--500, S = .C.050--C500--.050. For 
Replicate Checks, let D equal the loss that occurred between the first 
and second measurements. In summary:

T1 = T1
T2 = T2
T3 = T3
Z = ZC--0
C = C1000--1000
M = C500--500
G = C050--C500--.050

    Tabulate the mean and standard deviation for each of the following: 
Z, C, M, G. T1, T2, T3. Depending on the number of operators using the 
balance and the number of protocols in use, analyze the data by 
subcategories to determine the effects of balance operator and protocol. 
Each of these standard deviations, SZ, SC, etc. is 
an estimate of the precision of single weight measurement.
    For Z, C, M, and G, check the mean value for statistical difference 
from 0. If the means are statistically different than zero, 
troubleshooting to eliminate bias may be called for. For Z, C, M, G, T1, 
T2, T3, check that the standard deviations are all comparable. If there 
are systematic differences, then troubleshooting to eliminate the 
problem may be called for.
    Note that the precision of a weight gain, involves two weight 
determinations, and therefore is larger than S by a factor of sqrt(2). 
On the other hand replicate weighings improves the precision of the 
determinations by a factor of sqrt(N). If N = 2, i.e., duplicates, then 
the factors cancel each other.
    To estimate the overall uncertainty in a weight determination, a 
conservative estimate might be to combine the imprecision contributed by 
the zero with the imprecision contributed by the calibration.

U = Sqrt(SZ\2\ + SC\2\)

    The uncertainty in a weight gain from N replicates is then given by:

Ugain = Sqrt(2) x Sqrt(SZ\2\ + SC\2\)/
          Sqrt(N)

    But due to the balance adjustment and reweigh tolerances, we expect 
SZ to approximately equal SC, to approximately 
equal SM, etc. tolerances, so that the equation above 
becomes:

Ugain = 2 x S/Sqrt(N)


[[Page 221]]


Where S is any individual standard deviation; or better, a pooled 
          standard deviation.

    12.13 Method performance
    The data necessary to characterize the accuracy and precision of 
this method are still being collected. The method is used primarily to 
weigh objects before and after a period of soaking to determine weight 
loss by subtraction. Given the reweigh tolerances, we expect that the 
precision of weight gain determinations will be on the order of 0.006 g 
at the 1-sigma level. Bias in the weight gain determination, due to 
inaccuracy of the calibration weight and to fixed non-linearity of the 
balance response is on the order 0.005 percent of the gain.
    12.14 Pollution prevention
    When discharging half the can contents during can preparation, do 
not vent the contents of the small can to the atmosphere. Use an 
automotive recovery machine to transfer small can contest to a recovery 
cylinder.
    12.15 Waste management
    Dispose of the contents of the recycle cylinder through a service 
that consolidates waste for shipment to EPA certified facilities for 
reclaiming or destruction.

Section 13. Compensation of Weight Data for Buoyancy and Gravity Effects

    13.1 Gravity
    Variations in gravity are important only when weighing objects under 
different gravitational fields, i.e., at different locations or at 
different heights. Since the balance procedures calibrate the balance 
against a known mass (the calibration ``weight'') at the same location 
where sample objects are weighed, there is no need to correct for 
location. Although both the sample and the calibration weight are used 
at the same location, there will be a difference in the height of the 
center of gravity of the sample object (small can) and the center of 
gravity of the reference mass (calibration weight). However, this 
difference in height is maintained during both the initial weights and 
final weights, affecting the initial and final weights by the same 
amount, and affecting the scale of the weight difference by only a few 
ppm. In any event, the magnitude of this correction is on the order of 
0.3 ug per kg per mm of height difference. A difference on the order of 
100 mm would thus yield a weight difference of about 0.03 mg, which is 
insignificant compared to our balance resolution which is 0.001 g or 1 
mg.
    Based on the discussion above, no corrections for gravity are 
necessary when determining weight changes in small cans.
    13.2 Buoyancy
    Within a weighing session, the difference in density between the 
sample object and the calibration weight will cause the sample object 
weight value to differ from its mass value due to buoyancy. For a 1-
liter object in air at 20 [deg]C and at 1 atm, the buoyant force is 
about 1.2 g. The volume of a 1 kg object with a density of 8 g/cm\3\ 
(e.g., a calibration weight), is about 0.125 liters, and the buoyancy 
force is about 0.15 g. Variations in air density will affect both of 
these values in proportion. The net value being affected by variations 
in air density is thus on the order of 1.2 - 0.15 = 1.05 g. Air density 
can vary up or down by 2 percent or more due to variations in barometric 
pressure, temperature, and humidity. The buoyancy force will then vary 
up or down by 0.02 g, or 20 mg. This is significant compared to the 
weight change expected after one week for a can leaking at 3 grams per 
year, which is 57 mg.
    Based on the discussion above, buoyancy corrections must be made.
    Variables measured or calculated:

Vcan = volume of can (cm\3\). Estimate to within 10 percent 
          by measuring the can dimensions or by water displacement. 
          Error in the can volume will cause an error in the absolute 
          amount of the buoyancy force, but will have only a small 
          effect on the change in buoyancy force from day to day.
Wcan = nominal weight of a can (g), used to calculate the 
          nominal density of the can.
[rho]can = nominal density of a small can (g/cm\3\). The 
          nominal values can be applied to corrections for all cans. It 
          is not necessary to calculate a more exact density for each 
          can. Calculate once for a full can and once for a half full 
          can as follows:

[rho]can = Wcan /Vcan
T = Temperature in balance chamber (degrees Celsius).
RH = Relative humidity in balance chamber (expressed a number between 0 
          and 100).
Pbaro = Barometric pressure in balance chamber (millibar). 
          Use actual pressure, NOT pressure adjusted to sea level.
[rho]air = density of air in the balance chamber (g/cm\3\). 
          Calculate using the following approximation:
[rho]air = 0.001*[0.348444*Pbaro-(RH/100) x (0.252 
          x T-2.0582)]/(T + 273.15)
[rho]ref = the reference density of the calibration weight 
          (g/cm\3\). Should be 8.0 g/cm\3\.
Equation to correct for buoyancy: Wcorrected = 
          Wreading x (1--[rho]air/
          [rho]ref)/(1--[rho]air/
          [rho]can)

    Source: 59 FR 13147, Mar. 18, 1994, unless otherwise noted.

[[Page 222]]



Sec.82.170  Purpose and scope.

    (a) The purpose of these regulations in this subpart is to implement 
section 612 of the Clean Air Act, as amended, regarding the safe 
alternatives policy on the acceptability of substitutes for ozone-
depleting compounds. This program will henceforth be referred to as the 
``Significant New Alternatives Policy'' (SNAP) program. The objectives 
of this program are to identify substitutes for ozone-depleting 
compounds, to evaluate the acceptability of those substitutes, to 
promote the use of those substitutes believed to present lower overall 
risks to human health and the environment, relative to the class I and 
class II compounds being replaced, as well as to other substitutes for 
the same end-use, and to prohibit the use of those substitutes found, 
based on the same comparisons, to increase overall risks.
    (b) The regulations in this subpart describe persons and substitutes 
subject to reporting requirements under the SNAP program and explain 
preparation and submission of notices and petitions on substitutes. The 
regulations also establish Agency procedures for reviewing and 
processing EPA's determinations regarding notices and petitions on 
substitutes. Finally, the regulations prohibit the use of alternatives 
which EPA has determined may have adverse effects on human health or the 
environment where EPA has identified alternatives in particular 
industrial use sectors that on an overall basis, reduce risk to human 
health and the environment and are currently or potentially available. 
EPA will only prohibit substitutes where it has identified other 
substitutes for a specific application that are acceptable and are 
currently or potentially available.
    (c) Notifications, petitions and other materials requested shall be 
sent to: SNAP Document Control Officer, U.S. Environmental Protection 
Agency (6205-J), 1200 Pennsylvania Ave., NW., Washington, DC 20460.

[59 FR 13147, Mar. 18, 1994, as amended at 59 FR 63256, Dec. 8, 1994; 60 
FR 3303, Jan. 13, 1995]



Sec.82.176  Applicability.

    (a) Any producer of a new substitute must submit a notice of intent 
to introduce a substitute into interstate commerce 90 days prior to such 
introduction. Any producer of an existing substitute already in 
interstate commerce must submit a notice as of July 18, 1994, if such 
substitute has not already been reviewed and approved by the Agency.
    (b) With respect to the following substitutes, producers are exempt 
from notification requirements:
    (1) Substitutes already listed as acceptable. Producers need not 
submit notices on substitutes that are already listed as acceptable 
under SNAP.
    (2) Small sectors. Persons using substitutes in sectors other than 
the nine principal sectors reviewed under this program are exempt from 
the notification requirements. This exemption shall not be construed to 
nullify an unacceptability determination or to allow use of an otherwise 
unacceptable substitute.
    (3) Small volume use within SNAP sectors. Within the nine principal 
SNAP sectors, persons introducing a substitute whose expected volume of 
use amounts to less than 10,000 lbs. per year within a SNAP sector are 
exempt from notification requirements. This exemption shall not be 
construed to allow use of an otherwise unacceptable substitute in any 
quantity. Persons taking advantage of this exemption for small uses must 
maintain documentation for each substitute describing how the substitute 
meets this small use definition. This documentation must include annual 
production and sales information by sector.
    (4) Research and development. Production of substitutes for the sole 
purpose of research and development is exempt from reporting 
requirements.
    (5) Test marketing. Use of substitutes for the sole purpose of test 
marketing

[[Page 225]]

is exempt from SNAP notification requirements until 90 days prior to the 
introduction of such substitutes for full-scale commercial sale in 
interstate commerce. Persons taking advantage of this exemption are, 
however, required to notify the Agency in writing that they are 
conducting test marketing 30 days prior to the commencement of such 
marketing. Notification shall include the name of the substitute, the 
volume used in the test marketing, intended sector end-uses, and 
expected duration of the test marketing period.
    (6) Formulation changes. In cases where replacement of class I or II 
compounds causes formulators to change other components in a product, 
formulators are exempt from reporting with respect to these auxiliary 
formulation changes. However, the SNAP submitter is required to notify 
the Agency if such changes are expected to significantly increase the 
environmental and human health risk associated with the use of any class 
I or class II substitute.
    (7) Substitutes used as feedstocks. Producers of substitutes used as 
feedstocks which are largely or entirely consumed, transformed or 
destroyed in the manufacturing or use process are exempt from reporting 
requirements concerning such substitutes.
    (c) Use of a substitute in the possession of an end-user as of March 
18, 1994, listed as unacceptable or acceptable subject to narrowed use 
limits may continue until the individual end-users' existing supply, as 
of that date, of the substitute is exhausted. Use of substitutes 
purchased after March 18, 1994, is not permitted subsequent to April 18, 
1994.



Sec.82.178  Information required to be submitted.

    (a) Persons whose substitutes are subject to reporting requirements 
pursuant to Sec.82.176 must provide the following information:
    (1) Name and description of the substitute. The substitute should be 
identified by its: Chemical name; trade name(s); identification numbers; 
chemical formula; and chemical structure.
    (2) Physical and chemical information. The substitute should be 
characterized by its key properties including but not limited to: 
Molecular weight; physical state; melting point; boiling point; density; 
taste and/or odor threshold; solubility; partition coefficients (Log 
Kow, Log Koc); atmospheric lifetime and vapor 
pressure.
    (3) Substitute applications. Identification of the applications 
within each sector end-use in which the substitutes are likely to be 
used.
    (4) Process description. For each application identified, 
descriptive data on processing, including in-place pollution controls.
    (5) Ozone depletion potential. The predicted 100-year ozone 
depletion potential (ODP) of substitute chemicals. The submitter must 
also provide supporting documentation or references.
    (6) Global warming impacts. Data on the total global warming 
potential of the substitute, including information on the GWP index and 
the indirect contributions to global warming caused by the production or 
use of the substitute (e.g., changes in energy efficiency). GWP must be 
calculated over a 100, 500 and 1000-year integrated time horizon.
    (7) Toxicity data. Health and safety studies on the effects of a 
substitute, its components, its impurities, and its degradation products 
on any organism (e.g., humans, mammals, fish, wildlife, and plants). For 
tests on mammals, the Agency requires a minimum submission of the 
following tests to characterize substitute risks: A range-finding study 
that considers the appropriate exposure pathway for the specific use 
(e.g., oral ingestion, inhalation, etc.), and a 90-day subchronic 
repeated dose study in an appropriate rodent species. For certain 
substitutes, a cardiotoxicity study is also required. Additional 
mammalian toxicity tests may be identified based on the substitute and 
application in question. To sufficiently characterize aquatic toxicity 
concerns, both acute and chronic toxicity data for a variety of species 
are required. For this purpose, the Agency requires a minimum data set 
as described in ``Guidelines for Deriving Numerical National Water 
Quality Criteria for the Protection of Aquatic Organisms and their 
Uses,'' which is available through the National Technical Information 
Service (PB 85-227049). Other relevant information and

[[Page 226]]

data summaries, such as the Material Safety Data Sheets (MSDS), should 
also be submitted. To assist in locating any studies previously 
submitted to EPA and referred to, but not included in a SNAP submission, 
the submitter must provide citations for the date, type of submission, 
and EPA Office to which they were submitted, to help EPA locate these 
quickly.
    (8) Environmental fate and transport. Where available, information 
must be submitted on the environmental fate and transport of 
substitutes. Such data shall include information on bioaccumulation, 
biodegradation, adsorption, volatility, transformation, and other data 
necessary to characterize movement and reaction of substitutes in the 
environment.
    (9) Flammability. Data on the flammability of a substitute chemical 
or mixture are required. Specifically, the flash point and flammability 
limits are needed, as well as information on the procedures used for 
determining the flammability limits. Testing of blends should identify 
the compositions for which the blend itself is flammable and include 
fractionation data on changes in the composition of the blend during 
various leak scenarios. For substitutes that will be used in consumer 
applications, documentation of testing results conducted by independent 
laboratories should be submitted, where available. If a substitute is 
flammable, the submitter must analyze the risk of fire resulting from 
the use of such a substitute and assess the effectiveness of measures to 
minimize such risk.
    (10) Exposure data. Available modeling or monitoring data on 
exposures associated with the manufacture, formulation, transport, use 
and disposal of a substitute. Descriptive process information for each 
substitute application, as described above, will be used to develop 
exposure estimates where exposure data are not readily available. 
Depending on the application, exposure profiles may be needed for 
workers, consumers, and the general population.
    (11) Environmental release data. Data on emissions from the 
substitute application and equipment, as well as on pollutant releases 
or discharge to all environmental media. Submitters should provide 
information on release locations, and data on the quantities, including 
volume, of anticipated waste associated with the use of the substitute. 
In addition, information on anticipated waste management practices 
associated with the use of the substitute. Any available information on 
any pollution controls used or that could be used in association with 
the substitute (e.g., emissions reduction technologies, wastewater 
treatment, treatment of hazardous waste) and the costs of such 
technology must also be submitted.
    (12) Replacement ratio for a chemical substitute. Information on the 
replacement ratio for a chemical substitute versus the class I or II 
substances being replaced. The term ``replacement ratio'' means how much 
of a substitute must be used to replace a given quantity of the class I 
or II substance being replaced.
    (13) Required changes in use technology. Detail on the changes in 
technology needed to use the alternative. Such information should 
include a description of whether the substitute can be used in existing 
equipment--with or without some retrofit--or only in new equipment. Data 
on the cost (capital and operating expenditures) and estimated life of 
any technology modifications should also be submitted.
    (14) Cost of substitute. Data on the expected average cost of the 
alternative. In addition, information is needed on the expected 
equipment lifetime for an alternative technology. Other critical cost 
considerations should be identified, as appropriate.
    (15) Availability of substitute. If the substitute is not currently 
available, the timing of availability of a substitute should be 
provided.
    (16) Anticipated market share. Data on the anticipated near-term and 
long-term nationwide substitute sales.
    (17) Applicable regulations under other environmental statutes. 
Information on whether the substitute is regulated under other statutory 
authorities, in particular the Clean Water Act, Safe Drinking Water Act, 
the Resource Conservation and Recovery Act, the Federal Insecticide, 
Fungicide, and Rodenticide Act, the Toxic Substances Control Act, the 
Comprehensive Environmental Response, Compensation

[[Page 227]]

and Liability Act, the Emergency Planning and Community Right-to-Know 
Act, or other titles under the Clean Air Act.
    (18) Information already submitted to the Agency. Information 
requested in the SNAP program notice that has been previously submitted 
to the Agency as part of past regulatory and information-gathering 
activities may be referenced rather than resubmitted. Submitters who 
cannot provide accurate references to data sent previously to the Agency 
should include all requested information in the SNAP notice.
    (19) Information already available in the literature. If any of the 
data needed to complete the SNAP program notice are available in the 
public literature, complete references for such information should be 
provided.
    (b) The Significant New Alternatives Policy (SNAP) Information 
Notice is designed to provide the Agency with the information necessary 
to reach a decision on the acceptability of a substitute.
    (1) Submitters requesting review under the SNAP program should send 
the completed SNAP notice to: SNAP Document Control Officer, U.S. 
Environmental Protection Agency (6205-J), 1200 Pennsylvania Ave., NW., 
Washington, DC 20460.
    (2) Submitters filing jointly under SNAP and the Premanufacture 
Notice Program (PMN) should send the SNAP addendum along with the PMN 
form to: PMN Document Control Officer, U.S. Environmental Protection 
Agency (7407), 1200 Pennsylvania Ave., NW., Washington, DC 20460. 
Submitters must also send both documents to the SNAP program, with a 
reference to indicate the notice has been furnished to the Agency under 
the PMN program. Submitters providing information on new chemicals for 
joint review under the TSCA and SNAP programs may be required to supply 
additional toxicity data under TSCA section 5.
    (3) Submitters filing jointly under SNAP and under the Federal 
Insecticide, Fungicide, and Rodenticide Act should send the SNAP form to 
the Office of Pesticide Programs, Registration Division, (7505C) 1200 
Pennsylvania Ave., NW., Washington, DC 20460, as well as to the SNAP 
Document Control Officer.



Sec.82.180  Agency review of SNAP submissions.

    (a) Processing of SNAP notices--(1) 90-day review process. The 90-
day review process will begin once EPA receives a submission and 
determines that such submission includes data on the substitute that are 
complete and adequate, as described in Sec.82.178. The Agency may 
suspend or extend the review period to allow for submission of 
additional data needed to complete the review of the notice.
    (2) Initial review of notice. The SNAP Document Control Officer will 
review the notice to ensure that basic information necessary to process 
the submission is present (i.e., name of company, identification of 
substitute, etc.). The SNAP Document Control Officer will also review 
substantiation of any claim of confidentiality.
    (3) Determination of data adequacy. Upon receipt of the SNAP 
submission, the Agency will review the completeness of the information 
supporting the application. If additional data are needed, the submitter 
will be contacted following completion of this review. The 90-day review 
period will not commence until EPA has received data it judges adequate 
to support analysis of the submission.
    (4) Letter of receipt. The SNAP Document Control Officer will send a 
letter of receipt to the submitter to confirm the date of notification 
and the beginning of EPA's 90-day review period. The SNAP Document 
Control Officer will also assign the SNAP notice a tracking number, 
which will be identified in the letter of receipt.
    (5) Availability of new information during review period. If 
critical new information becomes available during the review period that 
may influence the Agency's evaluation of a substitute, the submitter 
must notify the Agency about the existence of such information within 10 
days of learning of such data. The submitter must also inform the Agency 
of new studies underway, even if the results will not be available 
within the 90-day review period. The Agency may contact the submitter to

[[Page 228]]

explore extending or suspending the review period depending on the type 
of information received and the stage of review.
    (6) Completion of detailed review. Once the initial data review, 
described in paragraphs (a)(2) and (3) of this section, has been 
completed, the Agency will complete a detailed evaluation of the notice. 
If during any time the Agency perceives a lack of information necessary 
to reach a SNAP determination, it will contact the submitter and request 
the missing data.
    (7) Criteria for review. To determine whether a substitute is 
acceptable or unacceptable as a replacement for class I or II compounds, 
the Agency will evaluate:
    (i) Atmospheric effects and related health and environmental 
impacts;
    (ii) General population risks from ambient exposure to compounds 
with direct toxicity and to increased ground-level ozone;
    (iii) Ecosystem risks;
    (iv) Occupational risks;
    (v) Consumer risks;
    (vi) Flammability; and
    (vii) Cost and availability of the substitute.
    (8) Communication of decision--(i) Communication of decision to the 
submitter. Once the SNAP program review has been completed, the Agency 
will notify the submitter in writing of the decision. Sale or 
manufacture of new substitutes may commence after the initial 90-day 
notification period expires even if the Agency fails to reach a decision 
within the 90-day review period or fails to communicate that decision or 
the need for additional data to the submitter. Sale or manufacture of 
existing substitutes may continue throughout the Agency's 90-day review.
    (ii) Communication of decision to the public. The Agency will 
publish in the Federal Register periodic updates to the list of the 
acceptable and unacceptable alternatives that have been reviewed to 
date. In the case of substitutes proposed as acceptable with use 
restrictions, proposed as unacceptable or proposed for removal from 
either list, a rulemaking process will ensue. Upon completion of such 
rulemaking, EPA will publish revised lists of substitutes acceptable 
subject to use conditions or narrowed use limits and unacceptable 
substitutes to be incorporated into the Code of Federal Regulations. 
(See Appendices to this subpart.)
    (b) Types of listing decisions. When reviewing substitutes, the 
Agency will list substitutes in one of five categories:
    (1) Acceptable. Where the Agency has reviewed a substitute and found 
no reason to prohibit its use, it will list the alternative as 
acceptable for the end-uses listed in the notice.
    (2) Acceptable subject to use conditions. After reviewing a notice, 
the Agency may make a determination that a substitute is acceptable only 
if conditions of use are met to minimize risks to human health and the 
environment. Where users intending to adopt a substitute acceptable 
subject to use conditions must make reasonable efforts to ascertain that 
other alternatives are not feasible due to safety, performance or 
technical reasons, documentation of this assessment must be retained on 
file for the purpose of demonstrating compliance. This documentation 
shall include descriptions of substitutes examined and rejected, 
processes or products in which the substitute is needed, reason for 
rejection of other alternatives, e.g., performance, technical or safety 
standards. Use of such substitutes in ways that are inconsistent with 
such use conditions renders them unacceptable.
    (3) Acceptable subject to narrowed use limits. Even though the 
Agency can restrict the use of a substitute based on the potential for 
adverse effects, it may be necessary to permit a narrowed range of use 
within a sector end-use because of the lack of alternatives for 
specialized applications. Users intending to adopt a substitute 
acceptable with narrowed use limits must ascertain that other 
alternatives are not technically feasible. Companies must document the 
results of their evaluation, and retain the results on file for the 
purpose of demonstrating compliance. This documentation shall include 
descriptions of substitutes examined and rejected, processes or products 
in which the substitute is needed, reason for rejection of other 
alternatives, e.g.,

[[Page 229]]

performance, technical or safety standards, and the anticipated date 
other substitutes will be available and projected time for switching to 
other available substitutes. Use of such substitutes in applications and 
end-uses which are not specified as acceptable in the narrowed use limit 
renders them unacceptable.
    (4) Unacceptable. This designation will apply to substitutes where 
the Agency's review indicates that the substitute poses risk of adverse 
effects to human health and the environment and that other alternatives 
exist that reduce overall risk.
    (5) Pending. Submissions for which the Agency has not reached a 
determination will be described as pending. For all substitutes in this 
category, the Agency will work with the submitter to obtain any missing 
information and to determine a schedule for providing the missing 
information if the Agency wishes to extend the 90-day review period. EPA 
will use the authority under section 114 of the Clean Air Act to gather 
this information, if necessary. In some instances, the Agency may also 
explore using additional statutory provisions (e.g., section 5 of TSCA) 
to collect the needed data.
    (c) Joint processing under SNAP and TSCA. The Agency will coordinate 
reviews of substitutes submitted for evaluation under both the TSCA PMN 
program and the CAA.
    (d) Joint processing under SNAP and FIFRA. The Agency will 
coordinate reviews of substitutes submitted for evaluation under both 
FIFRA and the CAA.

[59 FR 13147, Mar. 18, 1994, as amended at 61 FR 25592, May 22, 1996; 61 
FR 54039, Oct. 16, 1996]



Sec.82.182  Confidentiality of data.

    (a) Clean Air Act provisions. Anyone submitting information must 
assert a claim of confidentiality at the time of submission for any data 
they wish to have treated as confidential business information (CBI) 
under 40 CFR part 2, subpart B. Failure to assert a claim of 
confidentiality at the time of submission may result in disclosure of 
the information by the Agency without further notice to the submitter. 
The submitter should also be aware that under section 114(c), emissions 
data may not be claimed as confidential.
    (b) Substantiation of confidentiality claims. At the time of 
submission, EPA requires substantiation of any confidentiality claims 
made. Failure to provide any substantiation may result in disclosure of 
information without further notice by the Agency. All submissions must 
include adequate substantiation in order for an acceptability 
determination on a substitute to be published. Moreover, under 40 CFR 
part 2, subpart B, there are further instances in which confidentiality 
assertions may later be reviewed even when confidentiality claims are 
initially received. The submitter will also be contacted as part of such 
an evaluation process.
    (c) Confidentiality provisions for toxicity data. In the event that 
toxicity or health and safety studies are listed as confidential, this 
information cannot be maintained as confidential where such data are 
also submitted under TSCA or FIFRA, to the extent that confidential 
treatment is prohibited under those statutes. However, information 
contained in a toxicity study that is not health and safety data and is 
not relevant to the effects of a substance on human health and the 
environment (e.g., discussion of process information, proprietary 
blends) can be maintained as confidential subject to 40 CFR part 2, 
subpart B.
    (d) Joint submissions under other statutes. Information submitted as 
part of a joint submission to either SNAP/TSCA or SNAP/FIFRA must adhere 
to the security provisions of the program offices implementing these 
statutes. For such submissions, the SNAP handling of such notices will 
follow the security provisions under these statutes.



Sec.82.184  Petitions.

    (a) Who may petition. Any person may petition the Agency to amend 
existing listing decisions under the SNAP program, or to add a new 
substance to any of the SNAP lists.
    (b) Types of petitions. Five types of petitions exist:
    (1) Petitions to add a substitute not previously reviewed under the 
SNAP program to the acceptable list. This type of petition is comparable 
to the

[[Page 230]]

90-day notifications, except that it would generally be initiated by 
entities other than the companies that manufacture, formulate, or 
otherwise use the substitute. Companies that manufacture, formulate, or 
use substitutes that want to have their substitutes added to the 
acceptable list should submit information on the substitute under the 
90-day review program;
    (2) Petitions to add a substitute not previously reviewed under the 
SNAP program to the unacceptable list;
    (3) Petitions to delete a substitute from the acceptable list and 
add it to the unacceptable list or to delete a substitute from the 
unacceptable and add it to the acceptable list;
    (4) Petitions to add or delete use restrictions on an acceptability 
listing.
    (5) Petitions to grandfather use of a substitute listed as 
unacceptable or acceptable subject to use restrictions.
    (c) Content of the petition. The Agency requires that the petitioner 
submit information on the type of action requested and the rationale for 
the petition. Petitions in paragraphs (b)(1) and (2) of this section 
must contain the information described in Sec.82.178, which lists the 
items to be submitted in a 90-day notification. For petitions that 
request the re-examination of a substitute previously reviewed under the 
SNAP program, the submitter must also reference the prior submittal or 
existing listing. Petitions to grandfather use of an unacceptable 
substitute must describe the applicability of the test to judge the 
appropriateness of Agency grandfathering as established by the United 
States District Court for the District of Columbia Circuit (see Sierra 
Club v. EPA, 719 F.2d 436 (D.C. Cir. 1983)). This test includes whether 
the new rule represents an abrupt departure from previously established 
practice, the extent to which a party relied on the previous rule, the 
degree of burden which application of the new rule would impose on the 
party, and the statutory interest in applying the new rule immediately.
    (d) Petition process. (1) Notification of affected companies. If the 
petition concerns a substitute previously either approved or restricted 
under the SNAP program, the Agency will contact the original submitter 
of that substitute.
    (2) Review for data adequacy. The Agency will review the petition 
for adequacy of data. As with a 90-day notice, the Agency may suspend 
review until the petitioner submits the information necessary to 
evaluate the petition. To reach a timely decision on substitutes, EPA 
may use collection authorities such as those contained in section 114 of 
the Clean Air Act as amended, as well as information collection 
provisions of other environmental statutes.
    (3) Review procedures. To evaluate the petition, the Agency may 
submit the petition for review to appropriate experts inside and outside 
the Agency.
    (4) Timing of determinations. If data are adequate, as described in 
Sec.82.180, the Agency will respond to the petition within 90 days of 
receiving a complete petition. If the petition is inadequately 
supported, the Agency will query the petitioner to fill any data gaps 
before the 90-day review period begins, or may deny the petition because 
data are inadequate.
    (5) Rulemaking procedures. EPA will initiate rulemaking whenever EPA 
grants a petition to add a substance to the list of unacceptable 
substitutes, remove a substance from any list, or change or create an 
acceptable listing by imposing or deleting use conditions or use limits.
    (6) Communication of decision. The Agency will inform petitioners 
within 90 days of receiving a complete petition whether their request 
has been granted or denied. If a petition is denied, the Agency will 
publish in the Federal Register an explanation of the determination. If 
a petition is granted, the Agency will publish the revised SNAP list 
incorporating the final petition decision within 6 months of reaching a 
determination or in the next scheduled update, if sooner, provided any 
required rulemaking has been completed within the shorter period.

  Sec. Appendix C to Subpart G of Part 82--Substitutes Subject to Use 
  Restrictions and Unacceptable Substitutes Listed in the May 22, 1996 
                   Final Rule, Effective June 21, 1996

  Refrigeration and Air Conditioning Sector--Acceptable Subject to Use 
                               Conditions

    HCFC Blend Delta and Blend Zeta are acceptable subject to the 
following conditions when used to retrofit a CFC-12 motor vehicle air 
conditioning system:
    1. Each refrigerant may only be used with a set of fittings that is 
unique to that refrigerant. These fittings (male or female, as 
appropriate) must be used with all containers of the refrigerant, on can 
taps, on recovery, recycling, and charging equipment, and on all air 
conditioning system service ports. These fittings must be designed to 
mechanically prevent cross-charging with another refrigerant. A 
refrigerant may only be used with the fittings and can taps specifically 
intended for that refrigerant. Using an adapter or deliberately 
modifying a fitting to use a different refrigerant will be a violation 
of this use condition. In addition, fittings shall meet the following 
criteria, derived from Society of Automotive Engineers (SAE) standards 
and recommended practices:
    a. When existing CFC-12 service ports are to be retrofitted, 
conversion assemblies shall attach to the CFC-12 fitting with a thread 
lock adhesive and/or a separate mechanical latching mechanism in a 
manner that permanently prevents the assembly from being removed.
    b. All conversion assemblies and new service ports must satisfy the 
vibration testing requirements of sections 3.2.1 or 3.2.2 of SAE J1660, 
as applicable, excluding references to SAE J639 and SAE J2064, which are 
specific to HFC-134a.
    c. In order to prevent discharge of refrigerant to the atmosphere, 
systems shall have a device to limit compressor operation before the 
pressure relief device will vent refrigerant. This requirement is waived 
for systems that do not feature such a pressure relief device.
    d. All CFC-12 service ports not retrofitted with conversion 
assemblies shall be rendered permanently incompatible for use with CFC-
12 related service equipment by fitting with a device attached with a 
thread lock adhesive and/or a separate mechanical latching mechanism in 
a manner that prevents the device from being removed.
    2. When a retrofit is performed, a label must be used as follows:
    a. The person conducting the retrofit must apply a label to the air 
conditioning system in the engine compartment that contains the 
following information:
    i. The name and address of the technician and the company performing 
the retrofit.
    ii. The date of the retrofit.
    iii. The trade name, charge amount, and, when applicable, the ASHRAE 
refrigerant numerical designation of the refrigerant.
    iv. The type, manufacturer, and amount of lubricant used.
    v. If the refrigerant is or contains an ozone-depleting substance, 
the phrase ``ozone depleter.''
    vi. If the refrigerant displays flammability limits as measured 
according to ASTM E681, the statement ``This refrigerant is FLAMMABLE. 
Take appropriate precautions.''
    b. This label must be large enough to be easily read and must be 
permanent.
    c. The background color must be unique to the refrigerant.
    d. The label must be affixed to the system over information related 
to the previous refrigerant, in a location not normally replaced during 
vehicle repair.
    e. Information on the previous refrigerant that cannot be covered by 
the new label must be permanently rendered unreadable.
    3. No substitute refrigerant may be used to ``top-off'' a system 
that uses another refrigerant. The original refrigerant must be 
recovered in accordance with regulations issued under section 609 of the 
CAA prior to charging with a substitute.

[61 FR 25592, May 22, 1996, as amended at 67 FR 4201, Jan. 29, 2002]

    Effective Date Note: At 61 FR 25592, May 22, 1996, appendix C to 
subpart G of part 82 was added. This appendix contains information 
collection and recordkeeping requirements that will not become effective 
until approval has been given by the Office of Management and Budget.

  Sec. Appendix D to Subpart G of Part 82--Substitutes Subject to Use 
                Restrictions and Unacceptable Substitutes

                          Summary of Decisions

  Refrigeration and Air Conditioning Sector Acceptable Subject to Use 
                               Conditions

    R-406A/``GHG''/``McCool'', ``GHG-HP'', ``GHG-X4''/``Autofrost''/
``Chill-It'', and ``Hot Shot''/``Kar Kool'' are acceptable substitutes 
for CFC-12 in retrofitted motor vehicle air conditioning systems (MVACs) 
subject to the use condition that a retrofit to these refrigerants must 
include replacing non-barrier hoses with barrier hoses.
    For all refrigerants submitted for use in motor vehicle air 
conditioning systems, subsequent to the effective date of this FRM, in 
addition to the information previously required in the March 18, 1994 
final SNAP rule (58 FR 13044), SNAP submissions must include 
specifications for the fittings similar to those found in SAE J639, 
samples of all fittings, and the detailed label described below at the 
same time as the initial SNAP submission, or the submission will be 
considered incomplete. Under section 612 of the Clean Air Act, 
substitutes for which submissions are incomplete may not be sold or 
used, regardless of other acceptability determinations, and the 
prohibition against sale of a new refrigerant will not end until 90 days 
after EPA determines the submission is complete.
    In addition, the use of a) R-406A/``GHG''/``McCool'', ``HCFC Blend 
Lambda''/``GHG-HP'', R-414A/``HCFC Blend Xi''/``GHG-X4/``Autofrost''/
``Chill-It'', R-414B/``Hot Shot''/``Kar Kool'', and R-416A/``HCFC Blend 
Beta''/``FREEZE 12'' as CFC-12 substitutes in retrofitted MVACs, and b) 
all refrigerants submitted for, and listed in, subsequent Notices of 
Acceptability as substitutes for CFC-12 in MVACs, must meet the 
following conditions.
    1. Each refrigerant may only be used with a set of fittings that is 
unique to that refrigerant. These fittings (male or female, as 
appropriate) must be designed by the manufacturer of the refrigerant. 
The manufacturer is responsible to ensure that the fittings meet all of 
the requirements listed below, including testing according to SAE 
standards. These fittings must be designed to mechanically prevent 
cross-charging with another refrigerant, including CFC-12.
    The fittings must be used on all containers of the refrigerant, on 
can taps, on recovery, recycling, and charging equipment, and on all air 
conditioning system service ports. A refrigerant may only be used with 
the fittings and can taps specifically intended for that refrigerant and 
designed by the manufacturer of the refrigerant. Using a refrigerant 
with a fitting designed by anyone else, even if it is different from 
fittings used with other refrigerants, is a violation of this use 
condition. Using an adapter or deliberately modifying a fitting to use a 
different refrigerant is a violation of this use condition.
    Fittings shall meet the following criteria, derived from Society of 
Automotive Engineers (SAE) standards and recommended practices:
    a. When existing CFC-12 service ports are retrofitted, conversion 
assemblies shall attach to the CFC-12 fitting with a thread lock 
adhesive and/or a separate mechanical latching mechanism in a manner 
that permanently prevents the assembly from being removed.
    b. All conversion assemblies and new service ports must satisfy the 
vibration testing requirements of section 3.2.1 or 3.2.2 of SAE J1660, 
as applicable, excluding references to SAE J639 and SAE J2064, which are 
specific to HFC-134a.
    c. In order to prevent discharge of refrigerant to the atmosphere, 
systems shall have a device to limit compressor operation before the 
pressure relief device will vent refrigerant.
    d. All CFC-12 service ports not retrofitted with conversion 
assemblies shall be rendered permanently incompatible for use with CFC-
12 related service equipment by fitting with a device attached with a 
thread lock adhesive and/or a separate mechanical latching mechanism in 
a manner that prevents the device from being removed.
    2. When a retrofit is performed, a label must be used as follows:
    a. The person conducting the retrofit must apply a label to the air 
conditioning system in the engine compartment that contains the 
following information:
    i. The name and address of the technician and the company performing 
the retrofit.
    ii. The date of the retrofit.
    iii. The trade name, charge amount, and, when applicable, the ASHRAE 
refrigerant numerical designation of the refrigerant.
    iv. The type, manufacturer, and amount of lubricant used.
    v. If the refrigerant is or contains an ozone-depleting substance, 
the phrase ``ozone depleter''.
    vi. If the refrigerant displays flammability limits as measured 
according to ASTM E681, the statement ``This refrigerant is FLAMMABLE. 
Take appropriate precautions.''
    b. The label must be large enough to be easily read and must be 
permanent.
    c. The background color must be unique to the refrigerant.
    d. The label must be affixed to the system over information related 
to the previous refrigerant, in a location not normally replaced during 
vehicle repair.
    e. In accordance with SAE J639, testing of labels must meet ANSI/UL 
969-1991.

[[Page 248]]

    f. Information on the previous refrigerant that cannot be covered by 
the new label must be rendered permanently unreadable.
    3. No substitute refrigerant may be used to ``top-off'' a system 
that uses another refrigerant. The original refrigerant must be 
recovered in accordance with regulations issued under section 609 of the 
CAA prior to charging with a substitute.

  Sec. Appendix H to Subpart G of Part 82--Substitutes Subject to Use 
    Restrictions and Unacceptable Substitutes, Effective May 28, 1999

  CFC-12 Automobile and Non-automobile Motor Vehicle Air Conditioners, 
                            Retrofit and New

                   Criteria for Uniqueness of Fittings

    (a) All fittings for alternative motor vehicle refrigerants must 
meet the following requirements:
    (1) High-side screw-on fittings for each refrigerant must differ 
from high-side screw-on fittings for all other refrigerants, including 
CFC-12, and from low-side screw-on fittings for CFC-12;
    (2) Low-side screw-on fittings for each refrigerant must differ from 
low-side screw-on fittings for all other refrigerants, including CFC-12;
    (3) High-side screw-on fittings for a given refrigerant must differ 
from low-side screw-on fittings for that refrigerant, to protect against 
connecting a low-pressure system to a high-pressure one;
    (4) High-side quick-connect fittings for each refrigerant must 
differ from high-side quick-connect fittings for all other refrigerants, 
including CFC-12 (if they exist);
    (5) Low-side quick-connect fittings for each refrigerant must differ 
from low-side quick-connect fittings for all other refrigerants, 
including CFC-12 (if they exist);
    (6) High-side quick-connect fittings for a given refrigerant must 
differ from low-side quick-connect fittings for that refrigerant, to 
protect against connecting a low-pressure system to a high-pressure one;
    (7) For each type of container, the fitting for each refrigerant 
must differ from the fitting for that type of container for all other 
refrigerants, including CFC-12.
    (b) For screw-on fittings, ``differ'' means that either the diameter 
must differ by at least \1/16\ inch or the thread direction must be 
reversed (i.e. right-handed vs. left-handed). Simply changing the thread 
pitch is not sufficient. For quick-connect fittings, ``differ'' means 
that a person using normal force and normal tools (including wrenches) 
must not be able to cross-connect fittings.
    (c) The sole exception to the \1/16\ inch difference requirement is 
the difference between the small can fittings for GHG-X4 and R-406A. The 
GHG-X4 small can fitting uses a metric measurement, and is slightly less 
than \1/16\ inch larger than the small can fitting for R-406A. EPA has 
concluded that these fittings will not cross-connect, and therefore they 
may be used.

2--Per OSHA requirements, protective gear (SCBA) should be available in the event personnel should reenter the
  area.
3--Discharge testing should be strictly limited to that which is essential to meet safety or performance
  requirements.
4--The agent should be recovered from the fire protection system in conjunction with testing or servicing, and
  recycled for later use or destroyed.
5--EPA has no intention of duplicating or displacing OSHA coverage related to the use of personal protective
  equipment (e.g., respiratory protection), fire protection, hazard communication, worker training or any other
  occupational safety and health standard with respect to halon substitutes.

Additional comments.
1--Discharge testing should be strictly limited to that which is essential to meet safety or performance
  requirements.
2--The agent should be recovered from the fire protection system in conjunction with testing or servicing, and
  recycled for later use or destroyed.
3--EPA has no intention of duplicating or displacing OSHA coverage related to the use of personal protective
  equipment (e.g., respiratory protection), fire protection, hazard communication, worker training or any other
  occupational safety and health standard with respect to halon substitutes.
4--As with other streaming agents, EPA recommends that potential risks of combustion by-products be labelled on
  the extinguisher (see UL 2129)

    Source: 63 FR 11096, Mar. 5, 1998, unless otherwise noted.



Sec.82.250  Purpose and scope.

    (a) The purpose of this subpart is to reduce the emissions of halon 
in accordance with section 608 of the Clean Air Act by banning the 
manufacture of halon blends; banning the intentional release of halons 
during repair, testing, and disposal of equipment containing halons and 
during technician training; requiring organizations that employ 
technicians to provide emissions reduction training; and requiring 
proper disposal of halons and equipment containing halons.
    (b) This subpart applies to any person testing, servicing, 
maintaining, repairing or disposing of equipment that contains halons or 
using such equipment during technician training. This subpart also 
applies to any person disposing of halons; to manufacturers of halon 
blends; and to organizations that employ technicians who service halon-
containing equipment.



Sec.82.260  Definitions.

    Halon-containing equipment means equipment used to store, transfer, 
and/or disperse halon.
    Disposal of halon means the process leading to and including 
discarding of halon from halon-containing equipment.
    Disposal of halon-containing equipment means the process leading to 
and including:
    (1) The discharge, deposit, dumping or placing of any discarded 
halon-containing equipment into or on any land or water;
    (2) The disassembly of any halon-containing equipment for discharge, 
deposit, or dumping or placing of its discarded component parts into or 
on any land or water; or
    (3) The disassembly of any halon-containing equipment for reuse of 
its component parts.
    Halon means any of the Class I, Group II substances listed in 
subpart A, appendix A of 40 CFR part 82. This group consists of the 
three halogenated hydrocarbons known as Halon 1211, Halon 1301, and 
Halon 2402, and all isomers of these chemicals.

from equipment into the atmosphere. Technician also means any person who 
performs disposal of equipment that could reasonably be expected to 
release halons from the equipment into the atmosphere. Technician 
includes but is not limited to installers, contractor employees, in-
house service personnel, and in some cases, owners.



Sec.82.270  Prohibitions.

    (a) Effective April 6, 1998 no person may newly manufacture any 
halon blend. Halon blends manufactured solely for the purpose of 
aviation fire protection are not subject to this prohibition, provided 
that:
    (1) The manufacturer or its designee is capable of recycling the 
blend to the relevant industry standards for the chemical purity of each 
individual halon;
    (2) The manufacturer includes in all sales contracts for blends 
produced by it on or after April 6, 1998 the provision that the blend 
must be returned to it or its designee for recycling; and
    (3) The manufacturer or its designee in fact recycles blends 
produced by the manufacturer on or after April 6, 1998 and returned to 
it for recycling to the relevant industry standards for the chemical 
purity of each individual halon.
    (b) Effective April 6, 1998, no person testing, maintaining, 
servicing, repairing, or disposing of halon-containing equipment or 
using such equipment for technician training may knowingly vent or 
otherwise release into the environment any halons used in such 
equipment.
    (1) De minimis releases associated with good faith attempts to 
recycle or recover halon are not subject to this prohibition.
    (2) Release of residual halon contained in fully discharged total 
flooding fire extinguishing systems would be considered a de minimis 
release associated with good faith attempts to recycle or recover halon.
    (3) Release of halons during testing of fire extinguishing systems 
is not subject to this prohibition if the following four conditions are 
met:
    (i) Systems or equipment employing suitable alternative fire 
extinguishing agents are not available;
    (ii) System or equipment testing requiring release of extinguishing 
agent is essential to demonstrate system or equipment functionality;
    (iii) Failure of the system or equipment would pose great risk to 
human safety or the environment; and
    (iv) A simulant agent cannot be used in place of the halon during 
system or equipment testing for technical reasons.
    (4) Releases of halons associated with research and development of 
halon alternatives, and releases of halons necessary during analytical 
determination of halon purity using established laboratory practices are 
exempt from this prohibition.
    (5) This prohibition does not apply to qualification and development 
testing during the design and development process of halon-containing 
systems or equipment when such tests are essential to demonstrate system 
or equipment functionality and when a suitable simulant agent can not be 
used in place of the halon for technical reasons.
    (6) This prohibition does not apply to the emergency release of 
halons for the legitimate purpose of fire extinguishing, explosion 
inertion, or other emergency applications for which the equipment or 
systems were designed.
    (c) Effective April 6, 1998, organizations that employ technicians 
who

[[Page 312]]

test, maintain, service, repair or dispose of halon-containing equipment 
shall take appropriate steps to ensure that technicians hired on or 
before April 6, 1998 will be trained regarding halon emissions reduction 
by September 1, 1998. Technicians hired after April 6, 1998 shall be 
trained regarding halon emissions reduction within 30 days of hiring, or 
by September 1, 1998, whichever is later.
    (d) Effective April 6, 1998, no person shall dispose of halon-
containing equipment except by sending it for halon recovery to a 
manufacturer operating in accordance with NFPA 10 and NFPA 12A 
standards, a fire equipment dealer operating in accordance with NFPA 10 
and NFPA 12A standards or a recycler operating in accordance with NFPA 
10 and NFPA 12A standards. This provision does not apply to ancillary 
system devices such as electrical detection control components which are 
not necessary to the safe and secure containment of the halon within the 
equipment, to fully discharged total flooding systems, or to equipment 
containing only de minimis quantities of halons.
    (e) No person shall dispose of halon except by sending it for 
recycling to a recycler operating in accordance with NFPA 10 and NFPA 
12A standards, or by arranging for its destruction using one of the 
controlled processes approved by the Parties and listed in the 
definition of destruction in Sec.82.3.
    (f) Effective April 6, 1998, no owner of halon-containing equipment 
shall allow halon release to occur as a result of failure to maintain 
such equipment.

                               Prohibition

    Source: 76 FR 19866, Apr. 8, 2011, unless otherwise noted.



Sec.85.501  General applicability.

    (a) This subpart describes the provisions related to an exemption 
from the tampering prohibition in Clean Air Act section 203(a) (42 
U.S.C. 7522(a)) for light-duty vehicles, light-duty trucks, medium-duty 
passenger vehicles, heavy-duty vehicles, and heavy-duty engines. This 
subpart F does not apply for highway motorcycles or for nonroad or 
stationary engines or equipment.
    (b) For purposes of this subpart, the term ``you'' generally means a 
clean alternative fuel conversion manufacturer, which may also be called 
``conversion manufacturer'' or ``converter''.



Sec.85.502  Definitions.

    The definitions in this section apply to this subpart. All terms 
that are not defined in this subpart have the meaning given in 40 CFR 
part 86. All terms that are not defined in this subpart or in 40 CFR 
part 86 have the meaning given in the Clean Air Act. The definitions 
follow:
    Clean alternative fuel conversion (or ``fuel conversion'' or 
``conversion system'') means any alteration of a motor vehicle/engine, 
its fueling system, or the integration of these systems, that allows the 
vehicle/engine to operate on a fuel or power source different from the 
fuel or power source for which the vehicle/engine was originally 
certified; and that is designed, constructed, and applied consistent 
with good engineering judgment and in accordance with all applicable 
regulations. A clean alternative fuel conversion also means the 
components, design, and instructions to perform this alteration.
    Clean alternative fuel conversion manufacturer (or ``conversion 
manufacturer'' or ``converter'') means any person that manufactures, 
assembles, sells, imports, or installs a motor vehicle/engine fuel 
conversion for the purpose of use of a clean alternative fuel.
    Conversion model year means the clean alternative fuel conversion 
manufacturer's annual production period which includes January 1 of such 
calendar year. A specific model year may not include January 1 from the 
previous year or the following year. This is based on the expectation 
that production periods generally run on consistent schedules from year 
to year. Conversion model years may not circumvent or skip an annual 
production period. The term conversion model year means the calendar 
year if the converter does not have a different annual production 
period.
    Date of conversion means the date on which the clean alternative 
fuel conversion system is fully installed and operable.
    Dedicated vehicle/engine means any vehicle/engine engineered and 
designed to be operated using a single fuel.
    Dual-fuel vehicle/engine means any vehicle/engine engineered and 
designed to be operated on two or more different fuels, but not on a 
mixture of the fuels.
    Heavy-duty engines describes all engines intended for use in heavy-
duty vehicles, covered under the applicability of 40 CFR part 86, 
subpart A.
    Light-duty and heavy-duty chassis certified vehicles describes all 
light-duty vehicles, light-duty trucks, medium duty passenger vehicles, 
and heavy-duty complete and incomplete vehicles covered under the 
applicability of 40 CFR part 86, subpart S.
    Mixed-fuel vehicle/engine means any vehicle/engine engineered and 
designed to be operated on the original fuel(s), alternative fuel(s), or 
a mixture of two or more fuels that are combusted together. Mixed-fuel 
vehicles/engines include flexible-fuel vehicles/engines as defined in 40 
CFR part 86 subpart S.

[[Page 316]]

    Original equipment manufacturer (OEM) means the original 
manufacturer of the new vehicle/engine or relating to the vehicle/engine 
in its original certified configuration.
    Original model year means the model year in which a vehicle/engine 
was originally certified by the original equipment manufacturer, as 
noted on the certificate and on the emission control information label.
    We (us, our) means the Administrator of the Environmental Protection 
Agency or any authorized representative.



Sec.85.505  Overview.

    (a) You are exempted from the tampering prohibition in Clean Air Act 
section 203(a)(3) (42 U.S.C. 7522)(a)(3) (``tampering'') if you satisfy 
all the provisions of this subpart.
    (b) The tampering exemption provisions described in this subpart are 
differentiated based on the age of the vehicle/engine at the point of 
conversion as follows:
    (1) ``New and relatively new'' refers to a vehicle/engine where the 
date of conversion is in a calendar year that is not more than one year 
after the original model year. See Sec.85.510 for provisions that 
apply specifically to new and relatively new vehicles/engines.
    (2) ``Intermediate age'' refers to a vehicle/engine that has not 
exceeded the useful life (in years, miles, or hours of operation) 
applicable to the vehicle/engine as originally certified, excluding new 
and relatively new vehicles/engines. See Sec.85.515 for provisions 
that apply specifically to intermediate-age vehicles/engines.
    (3) ``Outside useful life'' refers to any vehicle/engine that has 
exceeded the useful life (in years, miles, or hours of operation) 
applicable to the vehicle/engine as originally certified. See Sec.
85.520 for provisions that apply specifically to outside useful life 
vehicles/engines.
    (c) If the converted vehicle/engine is a dual-fuel or mixed-fuel 
vehicle/engine, you must submit test data using each type of fuel, 
except that if you wish to certify to the same standards as the OEM 
vehicle/engine, you may omit testing for the fuel originally used to 
certify the vehicle/engine if you comply with Sec.85.510(b)(10)(ii), 
(iii), and (iv), Sec.85.515(b)(10)(iii)(B), (C), and (D), or Sec.
85.520(b)(6)(iii)(B), (C), and (D), as applicable.
    (d) This subpart specifies certain reporting requirements. We may 
ask you to give us more information than we specify in this subpart to 
determine whether your vehicles/engines conform to the requirements of 
this subpart. We may ask you to give us less information or do less 
testing than we specify in this subpart.
    (e) EPA may require converters to submit vehicles/engines for EPA 
testing under any of the three age based programs. Under Sec.85.510 or 
Sec.85.515, if a vehicle/engine is selected for confirmatory testing 
as part of the demonstration and notification process, the vehicle/
engines must satisfy the applicable intermediate and full useful life 
standards using the appropriate deterioration factors to qualify for an 
exemption from the tampering prohibition. If an outside useful life 
vehicle/engine is selected for testing, the vehicle/engine must 
demonstrate that emissions are maintained or improved upon after 
conversion to qualify for an exemption from the tampering prohibition.
    (f) If you have previously used small volume conversion manufacturer 
or qualified small volume test group/engine family procedures and you 
may exceed the volume thresholds using the sum described in Sec.
85.535(f) to determine small volume status in 40 CFR 86.1838-01, 40 CFR 
86.098-14, and 40 CFR 86.096-24(e)(2) as appropriate, you must satisfy 
the requirements for conversion manufacturers who do not qualify for 
small volume exemptions or your exemption from tampering is no longer 
valid.
    (g) An exemption from the prohibition on tampering applies to 
previously issued alternative fuel conversion certificates of conformity 
for the applicable conversion test group/engine family and/or 
evaporative/refueling family, as long as the conditions under which the 
certificate was issued remain unchanged, such as small volume 
manufacturer or qualified small volume test group/engine family status. 
Your exemption from tampering is valid only if the conversion is 
installed on the OEM test groups/engine families and/or evaporative 
emissions/refueling families listed on the certificate.

[[Page 317]]

    (h) The applicable useful life of a clean alternative fuel converted 
vehicle/engine shall end at the same time the OEM vehicle's/engine's 
original useful life ends.



Sec.85.510  Exemption provisions for new and relatively new vehicles
/engines.

    (a) You are exempted from the tampering prohibition with respect to 
new and relatively new vehicles/engines if you certify the conversion 
system to the emission standards specified in Sec.85.525 as described 
in paragraph (b) in this section; you meet the labeling and packaging 
requirements in Sec.85.530 before you sell, import or otherwise 
facilitate the use of a clean alternative fuel conversion system; and 
you meet the liability, recordkeeping, and end of year reporting 
requirements in Sec.85.535.
    (b) Certification under this section must be based on the 
certification procedures such as those specified in 40 CFR part 86, 
subparts A, B, and S and 40 CFR part 1065, as applicable, subject to the 
following exceptions and special provisions:
    (1) Test groups and evaporative/refueling families for light-duty 
and heavy-duty chassis certified vehicles.
    (i) Small volume conversion manufacturers and qualified small volume 
test groups.
    (A) If criteria for small volume manufacturer or qualified small 
volume test groups are met as defined in 40 CFR 86.1838-01, you may 
combine light-duty vehicles or heavy-duty vehicles which can be chassis 
certified under 40 CFR part 86, subpart S using good engineering 
judgment into conversion test groups if the following criteria are 
satisfied instead of those specified in 40 CFR 86.1827-01.
    (1) Same OEM and OEM model year.
    (2) Same OBD group.
    (3) Same vehicle classification (e.g. light-duty vehicle, heavy-duty 
vehicle).
    (4) Engine displacement is within 15% of largest displacement or 50 
CID, whichever is larger.
    (5) Same number of cylinders or combustion chambers.
    (6) Same arrangement of cylinders or combustion chambers (e.g. in-
line, v-shaped).
    (7) Same combustion cycle (e.g., two stroke, four stroke, Otto-
cycle, diesel-cycle).
    (8) Same engine type (e.g. piston, rotary, turbine, air cooled vs. 
water cooled).
    (9) Same OEM fuel type (except otherwise similar gasoline and E85 
flexible-fuel vehicles may be combined into dedicated alternative fuel 
vehicles).
    (10) Same fuel metering system (e.g. throttle body injection vs. 
port injection).
    (11) Same catalyst construction (e.g. metal vs. ceramic substrate).
    (12) All converted vehicles are subject to the most stringent 
emission standards used in certifying the OEM test groups within the 
conversion test group.
    (B) EPA-established scaled assigned deterioration factors for both 
exhaust and evaporative emissions may be used for vehicles with over 
10,000 miles if the criteria for small volume manufacturer or qualified 
small volume test groups are met as defined in 40 CFR 86.1838-01. This 
deterioration factor will be adjusted according to vehicle or engine 
miles of operation. The deterioration factor is intended to predict the 
vehicle's emission levels at the end of the useful life. EPA may adjust 
these scaled assigned deterioration factors if we find the rate of 
deterioration non-constant or if the rate differs by fuel type.
    (C) As part of the conversion system description provided in the 
application for certification, conversion manufacturers using EPA 
assigned deterioration factors must present detailed information to 
confirm the durability of all relevant new and existing components and 
to explain why the conversion system will not harm the emission control 
system or degrade the emissions.
    (ii) Conversion evaporative/refueling families are identical to the 
OEM evaporative/refueling families unless the OEM evaporative emission 
system is no longer functionally necessary. You must create any new 
evaporative families according to 40 CFR 86.1821-01.
    (2) Engine families and evaporative/refueling families for heavy-
duty engines.

[[Page 318]]

    (i) Small volume conversion manufacturers and qualified small volume 
heavy-duty engine families.
    (A) If criteria for small volume manufacturer or qualified small 
volume engine families are met as defined in 40 CFR 86.098-14 and 40 CFR 
86.096-24(e)(2) you may combine heavy-duty engines using good 
engineering judgment into conversion engine families if the following 
criteria are satisfied instead of those specified in 40 CFR part 86, 
subpart A.
    (1) Same OEM.
    (2) Same OBD group after MY 2013.
    (3) Same service class (e.g. light heavy-duty diesel engines, medium 
heavy-duty diesel engines, heavy heavy-duty diesel engines).
    (4) Engine displacement is within 15% of largest displacement or 50 
CID, whichever is larger.
    (5) Same number of cylinders.
    (6) Same arrangement of cylinders.
    (7) Same combustion cycle.
    (8) Same method of air aspiration.
    (9) Same fuel type (e.g. diesel/gasoline).
    (10) Same fuel metering system (e.g. mechanical direct or electronic 
direct injection).
    (11) Same catalyst/filter construction (e.g. metal vs. ceramic 
substrate).
    (12) All converted engines are subject to the most stringent 
emission standards. For example, 2005 and 2007 heavy-duty diesel engines 
may be in the same family if they meet the most stringent (2007) 
standards.
    (13) Same emission control technology (e.g., internal or external 
EGR).
    (B) EPA-established scaled assigned deterioration factors for both 
exhaust and evaporative emissions may be used for engines with over 
10,000 miles if the criteria for small volume manufacturer or qualified 
small volume engine families are met as defined in 40 CFR 86.098-14 and 
40 CFR 86.096-24(e)(2). This deterioration factor will be adjusted 
according to vehicle or engine miles of operation. The deterioration 
factor is intended to predict the engine's emission levels at the end of 
the useful life. EPA may adjust these scaled assigned deterioration 
factors if we find the rate of deterioration non-constant or if the rate 
differs by fuel type.
    (C) As part of the conversion system description provided in the 
application for certification, conversion manufacturers using EPA 
assigned deterioration factors must present detailed information to 
confirm the durability of all relevant new and existing components and 
to explain why the conversion system will not harm the emission control 
system or degrade the emissions.
    (ii) Conversion evaporative/refueling families are identical to the 
OEM evaporative/refueling families unless the OEM evaporative emission 
system is no longer functionally necessary. You must create any new 
evaporative families according to 40 CFR 86.096-24(a).
    (3) Conversion test groups/engine families for small volume 
conversion manufacturers and qualified small volume test groups/engine 
families may include vehicles/engines that are subject to different OEM 
emission standards; however, all the vehicles/engines certified under 
this subpart in a single conversion test group/engine family are subject 
to the most stringent standards that apply for vehicles/engines included 
in the conversion test group/engine family. For example, if OEM vehicle 
test groups originally certified to Tier 2, Bin 4 and Bin 5 standards 
are in the same conversion test group for purposes of fuel conversion, 
all the vehicles certified in the conversion test group under this 
subpart are subject to the Tier 2, Bin 4 standards. Conversion 
manufacturers may choose to certify a conversion test group/engine 
family to a more stringent standard than the OEM did. The optional, more 
stringent standard would then apply to all OEM test groups/engine 
families within the conversion test group/engine family. This paragraph 
(b)(3) does not apply to conversions to dual-fuel/mixed-fuel vehicles/
engines, as provided in paragraph (b)(7) of this section.
    (4)-(5) [Reserved]
    (6) Durability testing is required unless the criteria for small 
volume manufacturer or qualified small volume test groups/engine 
families are met as defined in 40 CFR 86.1838-01, 40 CFR 86.098-14, and 
40 CFR 86.096-24(e)(2), as applicable.
    (7) Conversion test groups/engine families for conversions to dual-
fuel or

[[Page 319]]

mixed-fuel vehicles/engines cannot include vehicles/engines subject to 
different emission standards unless applicable exhaust and OBD 
demonstrations are also conducted for the original fuel(s) demonstrating 
compliance with the most stringent standard represented in the test 
group. However for small volume conversion manufacturers and qualified 
small volume test groups/engine families the data generated from exhaust 
emission testing on the new fuel for dual-fuel or mixed-fuel test 
vehicles/engines may be carried over to vehicles/engines which otherwise 
meet the test group/engine family criteria and for which the test 
vehicle/engine data demonstrate compliance with the application vehicle/
engine standard. Clean alternative fuel conversion evaporative families 
for dual-fuel or mixed-fuel vehicles may not include vehicles/engines 
which were originally certified to different evaporative emissions 
standards unless evaporative/refueling demonstrations are also conducted 
for the original fuel(s) demonstrating compliance with the most 
stringent standard represented in the evaporative/refueling family.
    (8) The vehicle/engine selected for testing must qualify as a worst-
case vehicle/engine under 40 CFR 86.1828-10 or 40 CFR 86.096-24(b)(2) 
through (b)(3), as applicable.
    (9) OBD requirements. (i) The OBD system must properly detect and 
identify malfunctions in all monitored emission-related powertrain 
systems or components including any new monitoring capability necessary 
to identify potential emission problems associated with the new fuel.
    (ii) Conduct all OBD testing necessary to demonstrate compliance 
with 40 CFR 86.010-18 or 86.1806-05.
    (iii) Submit the applicable OBD reporting requirements set forth in 
40 CFR part 86, subparts A and S, and submit the following statement of 
compliance if the OEM vehicles/engines were required to be OBD-equipped:
    The test group/engine family converted to an alternative fuel has 
fully functional OBD systems and therefore meets the OBD requirements 
specified in 40 CFR part 86 when operating on the alternative fuel.
    (10) In lieu of specific certification test data, you may submit the 
following attestations for the appropriate statements of compliance, if 
you have sufficient basis to prove the statement is valid.
    (i) The test group/engine family converted to an alternative fuel 
has properly exercised the optional and applicable statements of 
compliance or waivers in the certification regulations such as those 
specified in 40 CFR part 86, subparts A, B, and S and 40 CFR part 1065. 
Attest to each statement or waiver in your application for 
certification.
    (ii) The test group/engine family converted to dual-fuel or mixed-
fuel operation retains all the OEM fuel system, engine calibration, and 
emission control system functionality when operating on the fuel with 
which the vehicle/engine was originally certified.
    (iii) The test group/engine family converted to dual fuel or mixed-
fuel operation retains all the functionality of the OEM OBD system (if 
so equipped) when operating on the fuel with which the vehicle/engine 
was originally certified.
    (iv) The test group/engine family converted to dual-fuel or mixed-
fuel operation properly purges hydrocarbon vapor from the evaporative 
emission canister when the vehicle/engine is operating on the 
alternative fuel.
    (11) Certification fees apply per 40 CFR 1027.
    (12) A certificate issued under this section is valid starting with 
the indicated effective date and expires on December 31 of the 
conversion model year for which it is issued. You may apply for a 
certificate of conformity for the next conversion model year using the 
applicable provisions for carryover certification. Even after the 
certificate expires, your exemption from the prohibition on tampering 
remains valid for the applicable conversion test group/engine family 
and/or evaporative/refueling family, as long as the conditions under 
which the certificate was issued remain unchanged, such as small volume 
manufacturer or qualified small volume test group/engine family status. 
Your exemption from tampering is valid only if the conversion is 
installed on the OEM test

[[Page 320]]

groups/engine families and/or evaporative emissions/refueling families 
listed on the certificate. For example, if you have received a clean 
alternative fuel conversion certificate of conformity in conversion 
model year 2011 for converting a 2010 model year OEM test group/
evaporative/refueling family, your exemption from tampering continues to 
apply for the conversion of the same 2010 model year OEM test group/
evaporative/refueling family as long as the conditions under which the 
certificate was issued remain unchanged, such as small volume 
manufacturer status.
    (13) Conversion systems must be properly installed and adjusted such 
that the vehicle/engine operates consistent with the principles of good 
engineering judgment and in accordance with all applicable regulations.

Sec.85.515  Exemption provisions for intermediate age vehicles/engines.

    (a) You are exempted from the tampering prohibition with respect to 
intermediate age vehicles/engines if you properly test, document and 
notify EPA that the conversion system complies with the emission 
standards specified in Sec.85.525 as described in paragraph (b) of 
this section; you meet the labeling requirements in Sec.85.530 before 
you sell, import or otherwise facilitate the use of a clean alternative 
fuel conversion system; and you meet the liability, recordkeeping, and 
end of year reporting requirements in Sec.85.535. You may also meet 
the requirements under this section by complying with the requirements 
in Sec.85.510.
    (b) Documenting and notifying EPA under this section includes 
demonstrating compliance with all the provisions in this section and 
providing all notification information to EPA. You may notify us as 
described in this section instead of certifying the clean alternative 
fuel conversion system. You must demonstrate compliance with all exhaust 
and evaporative emissions standards by conducting all exhaust and 
evaporative emissions and durability testing as required for OEM 
certification subject to the exceptions and special provisions permitted 
in Sec.85.510. This paragraph (b) provides additional special 
provisions applicable to intermediate age vehicles/engines. Paragraph 
(b) is applicable to all conversion manufacturers unless otherwise 
specified.
    (1) Conversion test groups for light-duty and heavy-duty chassis 
certified vehicles may be grouped together into an exhaust conversion 
test group using the criteria described in Sec.85.510(b)(1)(i)(A), 
except that the same OBD group is not a criterion. Evaporative/refueling 
families may be grouped together using the criteria described in Sec.
85.510(b)(1)(ii).
    (2) Conversion engine families for heavy-duty engines may be grouped 
together into an exhaust conversion engine family using the criteria 
described in Sec.85.510(b)(2)(i)(A), except that the same OBD group is 
not a criterion. Evaporative/refueling families may be grouped together 
using the criteria described in Sec.85.510(b)(2)(ii).
    (3) Conversion test groups/engine families may include vehicles/
engines that are subject to different OEM emission standards; however, 
all vehicles/engines in a single conversion test group/engine family are 
subject to the most stringent standards that apply for vehicles/engines 
included in the conversion test group/engine family. For example, if OEM 
vehicle test groups originally certified to Tier 2, Bin 4 and Bin 5 
standards are in the same conversion test group for purposes of fuel 
conversion, all the vehicles in the conversion test group under this 
subpart are subject to the Tier 2, Bin 4 standards. This paragraph 
(b)(3) does not apply to conversions to dual-fuel/mixed-fuel vehicles/
engines, as provided in paragraph (b)(7).
    (4) EPA-established scaled assigned deterioration factors for both 
exhaust and evaporative emissions may be used for vehicles/engines with 
over 10,000 miles if the criteria for small volume manufacturer or 
qualified small volume test groups/engine families are met as defined in 
40 CFR 86.1838-01, 40 CFR 86.098-14, or 40 CFR 86.096-24(e)(2), as 
appropriate. This deterioration factor will be adjusted according to 
vehicle/engine miles or hours of operation. The deterioration factor is 
intended to predict the vehicle/engine's emission

[[Page 321]]

level at the end of the useful life. EPA may adjust these scaled 
assigned deterioration factors if we find the rate of deterioration non-
constant or if the rate differs by fuel type.
    (5) As part of the conversion system description required by 
paragraph (b)(10)(i) of this section, small volume conversion 
manufacturers and qualified small volume test groups/engine families 
using EPA assigned deterioration factors must present detailed 
information to confirm the durability of all relevant new and existing 
components and explain why the conversion system will not harm the 
emission control system or degrade the emissions.
    (6) Durability testing is required unless the criteria for small 
volume manufacturer or qualified small volume test groups/engine 
families are met as defined in 40 CFR 86.1838-01, 40 CFR 86.098-14, or 
40 CFR 86.096-24(e)(2), as applicable. Durability procedures for large 
volume conversion manufacturers of intermediate age light-duty and 
heavy-duty chassis certified vehicles that follow provisions in 40 CFR 
86.1820-01 may eliminate precious metal composition and catalyst 
grouping statistic when creating clean alternative fuel conversion 
durability groupings.
    (7) Conversion test groups/engine families for conversions to dual-
fuel or mixed-fuel vehicles/engines may not include vehicles/engines 
subject to different emissions standards unless applicable exhaust and 
OBD demonstrations are also conducted for the original fuel(s) 
demonstrating compliance with the most stringent standard represented in 
the test group/engine family. However the data generated from testing on 
the new fuel for dual-fuel or mixed/fuel test vehicles/engines may be 
carried over to vehicles/engines that otherwise meet the conversion test 
group/engine family criteria and for which the test vehicle/engine data 
demonstrate compliance with the applicable vehicle/engine standards. 
Clean alternative fuel conversion evaporative families for dual-fuel or 
mixed-fuel vehicles/engines cannot include vehicles/engines that were 
originally certified to different evaporative emissions standards unless 
evaporative/refueling demonstrations are also conducted for the original 
fuel(s) demonstrating compliance with the most stringent standard 
represented in the evaporative/refueling family.
    (8) You must conduct all exhaust and all evaporative and refueling 
emissions testing with a worst-case vehicle/engine to show that the 
conversion test group/engine family complies with exhaust and 
evaporative/refueling emission standards, based on the certification 
procedures such as those specified in 40 CFR part 86, subparts A, B, and 
S and 40 CFR part 1065.
    (9) OBD requirements. (i) The OBD system must properly detect and 
identify malfunctions in all monitored emission-related powertrain 
systems or components including any new monitoring capability necessary 
to identify potential emission problems associated with the new fuel. 
These include but are not limited to: Fuel trim lean and rich monitors, 
catalyst deterioration monitors, engine misfire monitors, oxygen sensor 
deterioration monitors, EGR system monitors, if applicable, and vapor 
leak monitors, if applicable. No original OBD system monitor that is 
still applicable to the vehicle/engine may be aliased, removed, 
bypassed, or turned-off. No MILs shall be illuminated after the 
conversion. Readiness flags must be properly set for all monitors that 
identify any malfunction for all monitored components.
    (ii) Subsequent to the vehicle/engine fuel conversion, you must 
clear all OBD codes and reset all OBD monitors to not-ready status using 
an OBD scan tool appropriate for the OBD system in the vehicle/engine in 
question. You must operate the vehicle/engine with the new fuel on 
representative road operation or chassis dynamometer/engine dynamometer 
testing cycles to satisfy the monitors' enabling criteria. When all 
monitors have reset to a ready status, you must submit an OBD scan tool 
report showing that with the vehicle/engine operating in the key-on/
engine-on mode, all supported monitors have reset to a ready status and 
no emission related ``pending'' (or potential) or ``confirmed'' (or MIL-
on) diagnostic trouble codes (DTCs) have been set. The MIL must not be 
commanded ``On'' or be illuminated. A MIL check must also be conducted 
in a key-on/engine-

[[Page 322]]

off mode to verify that the MIL is functioning properly. You must 
include the VIN/EIN number of the test vehicle/engine. If necessary, the 
OEM evaporative emission readiness monitor may remain unset for 
dedicated gaseous fuel conversion systems.
    (iii) In addition to conducting OBD testing described in this 
paragraph (b)(9), you must submit to EPA the following statement of 
compliance if the OEM vehicles/engines were required to be OBD-equipped:
    The test group/engine family converted to an alternative fuel has 
fully functional OBD systems and therefore meets the OBD requirements 
specified in 40 CFR part 86 when operating on the alternative fuel.
    (10) You must notify us by electronic submission in a format 
specified by the Administrator with all required documentation. The 
following must be submitted:
    (i) You must describe how your conversion system qualifies as a 
clean alternative fuel conversion. You must include emission test 
results from the required exhaust, evaporative emissions, and OBD 
testing, applicable exhaust and evaporative emissions standards and 
deterioration factors. You must also include a description of how the 
test vehicle/engine selected qualifies as a worst-case vehicle/engine 
under 40 CFR 86.1828-10 or 40 CFR 86.096-24(b)(2) through (b)(3) as 
applicable.
    (ii) You must describe the group of vehicles/engines (conversion 
test group/conversion engine family) that are covered by your 
notification based on the criteria specified in paragraph (b)(1) or 
(b)(2) of this section.
    (iii) In lieu of specific test data, you may submit the following 
attestations for the appropriate statements of compliance, if you have 
sufficient basis to prove the statement is valid.
    (A) The test group/engine family converted to an alternative fuel 
has properly exercised the optional and applicable statements of 
compliance or waivers in the certification regulations such as those 
specified in 40 CFR part 86, subparts A, B, and S and 40 CFR part 1065. 
Attest to each statement or waiver in your notification.
    (B) The test group/engine family converted to dual-fuel or mixed-
fuel operation retains all the OEM fuel system, engine calibration, and 
emission control system functionality when operating on the fuel with 
which the vehicle/engine was originally certified.
    (C) The test group/engine family converted to dual-fuel or mixed-
fuel operation retains all the functionality of the OEM OBD system (if 
the OEM vehicles/engines were required to be OBD equipped) when 
operating on the fuel for which the vehicle/engine was originally 
certified.
    (D) The test group/engine family converted to dual-fuel or mixed-
fuel operation properly purges hydrocarbon vapor from the evaporative 
emission canister when the vehicle/engine is operating on the 
alternative fuel.
    (iv) Include any other information as the Administrator may deem 
appropriate to establish that the conversion system is for the purpose 
of conversion to a clean alternative fuel and meets applicable emission 
standards.
    (11) [Reserved]
    (12) Your exemption from the prohibition on tampering remains valid 
for the applicable conversion test group/engine family and/or 
evaporative/refueling family, as long as the conditions under which you 
previously complied remain unchanged, such as small volume manufacturer 
or qualified small volume test group/engine family status. Your 
exemption from tampering is valid only if the conversion is installed on 
the OEM test groups/engine families and/or evaporative emissions/
refueling families listed on the notification. For example, if you have 
complied properly with the provisions in this section in calendar year 
2011 for converting a model year 2006 OEM test group/evaporative/
refueling family, your exemption from tampering continues to apply for 
the conversion of the same model year 2006 OEM test group/evaporative/
refueling family as long as the conditions under which the notification 
was submitted remain unchanged.
    (13) Conversion systems must be properly installed and adjusted such

[[Page 323]]

that the vehicle/engine operates consistent with the principles of good 
engineering judgment and in accordance with all applicable regulations.

Sec.85.520  Exemption provisions for outside useful life vehicles
/engines.

    (a) You are exempted from the tampering prohibition with respect to 
outside useful life vehicles/engines if you properly document and notify 
EPA that the conversion system satisfies all the provisions in this 
section; you meet the labeling requirements in Sec.85.530 before you 
sell, import or otherwise facilitate the use of a clean alternative fuel 
conversion system; and you meet the applicable requirements in Sec.
85.535. You may also meet the requirements under this section by 
complying with the provisions in Sec.85.515.
    (b) Documenting and notifying EPA under this section includes the 
following provisions:
    (1) You must notify us as described in this section.
    (2) Conversion test groups, evaporative/refueling families, and 
conversion engine families may be the same as those allowed for the 
intermediate age vehicle/engine program in Sec.85.515(b)(1) and (2).
    (3) You must use good engineering judgment to specify, use, and 
assemble fuel system components and other hardware and software that are 
properly designed and matched for the vehicles/engines in which they 
will be installed. Good engineering judgment also dictates that any 
testing or data used to satisfy demonstration requirements be generated 
at a quality laboratory that follows good laboratory practices and that 
is capable of performing official EPA emission tests.
    (4) OBD requirements. (i) The OBD system must properly detect and 
identify malfunctions in all monitored emission-related powertrain 
systems or components including any new monitoring capability necessary 
to identify potential emission problems associated with the new fuel. 
These include but are not limited to: Fuel trim lean and rich monitors, 
catalyst deterioration monitors, engine misfire monitors, oxygen sensor 
deterioration monitors, EGR system monitors, if applicable, and vapor 
leak monitors, if applicable. No original OBD system monitor that is

bypassed, or turned-off. No MILs shall be illuminated after the 
conversion. Readiness flags must be properly set for all monitors that 
identify any malfunction for all monitored components.
    (ii) Subsequent to the vehicle/engine fuel conversion, you must 
clear all OBD codes and reset all OBD monitors to not-ready status using 
an OBD scan tool appropriate for the OBD system in the vehicle/engine in 
question. You must operate the vehicle/engine with the new fuel on 
representative road operation or chassis dynamometer/engine dynamometer 
testing cycles to satisfy the monitors' enabling criteria. When all 
monitors have reset to a ready status, you must submit an OBD scan tool 
report showing that with the vehicle/engine operating in the key-on/
engine-on mode, all supported monitors have reset to a ready status and 
no emission related ``pending'' (or potential) or ``confirmed'' (or MIL-
on) diagnostic trouble codes (DTCs) have been stored. The MIL must not 
be commanded ``On'' or be illuminated. A MIL check must also be 
conducted in a key-on/engine-off mode to verify that the MIL is 
functioning properly. You must include the VIN/EIN number of the test 
vehicle/engine. If necessary, the OEM evaporative emission readiness 
monitor may remain unset for dedicated gaseous fuel conversion systems.
    (iii) In addition to conducting OBD testing described in this 
paragraph (b)(4), you must submit to EPA the following statement of 
compliance if the OEM vehicles/engines were required to be OBD-equipped:
    The test group/engine family converted to an alternative fuel has 
fully functional OBD systems and therefore meets the OBD requirements 
specified in 40 CFR part 86 when operating on the alternative fuel.
    (5) Conversion test groups/engine families for conversions to dual-
fuel or

mixed-fuel vehicles/engines may not include vehicles/engines subject to 
different emissions standards unless applicable exhaust and OBD 
demonstrations are also conducted for the original fuel(s) demonstrating 
compliance with the most stringent standard represented in the test 
group. However the data generated from testing on the new fuel for dual-
fuel or mixed-fuel test vehicles/engines may be carried over to 
vehicles/engines that otherwise meet the conversion test group/engine 
family criteria and for which the test vehicle/engine data demonstrate 
compliance with the applicable vehicle/engine standards. Clean

    (6) You must notify us by electronic submission in a format 
specified by the Administrator with all required documentation. The 
following must be submitted.
    (i) You must describe how your conversion system complies with the 
good engineering judgment criteria in Sec.85.520(b)(3) and/or other 
requirements under this subpart or other applicable subparts such that 
the conversion system qualifies as a clean alternative fuel conversion. 
The submission must provide a level of technical detail sufficient for 
EPA to confirm the conversion system's ability to maintain or improve on 
emission levels in a worst case vehicle/engine. The submission of 
technical information must include a complete characterization of 
exhaust and evaporative emissions control strategies, the fuel delivery 
system, durability, and specifications related to OBD system 
functionality. You must present detailed information to confirm the 
durability of all relevant new and existing components and to explain 
why the conversion system will not harm the emission control system or 
degrade the emissions. EPA may ask you to supply additional information, 
including test data, to support the claim that the conversion system 
does not increase emissions and involves good engineering judgment that 
is being applied for purposes of conversion to a clean alternative fuel.
    (ii) You must describe the group of vehicles/engines (conversion 
test group/conversion engine family) that is covered by your 
notification based on the criteria specified in paragraph (b)(2) of this

fuel operation properly purges hydrocarbon vapor from the evaporative 
emission canister when the vehicle/engine is operating on the 
alternative fuel.
    (E) The test group/engine family converted to an alternative fuel 
uses fueling systems, evaporative emission control systems, and engine 
powertrain components that are compatible with the alternative fuel and 
designed with the principles of good engineering judgment.
    (iv) You must include any other information as the Administrator may 
deem appropriate, which may include test data, to establish the 
conversion system is for the purpose of conversion to a clean 
alternative fuel.
    (7) Conversion systems must be properly installed and adjusted such

[76 FR 19866, Apr. 8, 2011, as amended at 79 FR 23681, Apr. 28, 2014]



Sec.85.524  Legacy standards.

    Prior to April 8, 2011, the following emission standards applied for 
conversions of vehicles/engines with an original model year of 1992 or 
earlier:
    (a) Exhaust hydrocarbons. Light-duty vehicles must meet the Tier 0 
hydrocarbon standard specified in 40 CFR 86.094-8. Light-duty trucks 
must meet the Tier 0 hydrocarbon standard specified in 40 CFR 86.094-9. 
Otto-cycle heavy-duty engines must meet the hydrocarbon standard 
specified in 40 CFR 86.096-10. Diesel heavy-duty engines must meet the 
hydrocarbon standard in 40 CFR 86.096-11.
    (b) CO, NOX and particulate matter. Vehicles/engines must 
meet the CO, NOX, and particulate matter emission standards 
that applied for the vehicle's/engine's original model year. If the 
engine was certified with a Family Emission Limit, as noted on the 
emission control information label, the modified engine may not exceed 
this Family Emission Limit.
    (c) Evaporative hydrocarbons. Vehicles/engines must meet the 
evaporative hydrocarbon emission standards that applied for the 
vehicle's/engine's original model year.



Sec.85.525  Applicable standards.

    To qualify for an exemption from the tampering prohibition, 
vehicles/engines that have been converted to operate on a different fuel 
must meet emission standards and related requirements as described in 
this section. The modified vehicle/engine must meet the requirements 
that applied for the OEM vehicle/engine, or the most stringent OEM 
vehicle/engine standards in any allowable grouping. Fleet average 
standards do not apply unless clean alternative fuel conversions are 
specifically listed as subject to the standards.
    (a) If the vehicle/engine was certified with a Family Emission Limit 
for NOX, NOX+HC, NOX+NMOG, or 
particulate matter, as noted on the vehicle/engine emission control 
information label, the modified vehicle/engine may not exceed this 
Family Emission Limit.
    (b) Compliance with greenhouse gas emission standards is 
demonstrated as follows:
    (1) Subject to the following exceptions and special provisions, 
compliance with light-duty vehicle greenhouse gas emission standards is 
demonstrated by complying with the N2O and CH4 
standards and provisions set forth in 40 CFR 86.1818-12(f)(1) and the 
in-use CO2 exhaust emission standard set forth in 40 CFR 
86.1818-12(d) as determined by the OEM for the subconfiguration that is 
identical to the fuel conversion emission data vehicle (EDV):
    (i) If the OEM complied with the light-duty greenhouse gas standards 
using the fleet averaging option for N2O and CH4, 
as allowed under 40 CFR 86.1818-12(f)(2), the calculations of the 
carbon-related exhaust emissions require the input of grams/mile values 
for N2O and CH4, and you are not required to 
demonstrate compliance with the standalone CH4 and 
N2O standards.
    (ii) If the OEM complied with alternate standards for N2O 
and/or CH4, as allowed under 40 CFR 86.1818-12(f)(3), you may 
demonstrate compliance with the same alternate standards.
    (iii) If the OEM complied with the nitrous oxide (N2O) 
and methane (CH4) standards and provisions set forth in 40 
CFR 86.1818-12(f)(1) or (3), and the fuel conversion CO2 
measured value is lower than the in-use CO2 exhaust emission 
standard, you also have the option to convert the difference between the 
in-use CO2 exhaust emission standard and the fuel conversion 
CO2 measured value into GHG equivalents of CH4 
and/or N2O, using 298 g CO2 to represent 1 g 
N2O and 25 g CO2 to represent 1 g CH4. 
You may then subtract the applicable converted values from the fuel 
conversion measured values of CH4 and/or N2O to 
demonstrate compliance with the CH4 and/or N2O 
standards.
    (iv) Optionally, compliance with greenhouse gas emission 
requirements may be demonstrated by comparing emissions from the vehicle 
prior to the fuel conversion to the emissions after

[[Page 326]]

the fuel conversion. This comparison must be based on FTP test results 
from the emission data vehicle (EDV) representing the pre-conversion 
test group. The sum of CO2, CH4, and 
N2O shall be calculated for pre- and post-conversion FTP test 
results, where CH4 and N2O are weighted by their 
global warming potentials of 25 and 298, respectively. The post-
conversion sum of these emissions must be lower than the pre-conversion 
conversion greenhouse gas emission results. CO2 emissions are 
calculated as specified in 40 CFR 600.113-12. If statements of 
compliance are applicable and accepted in lieu of measuring 
N2O, as permitted by EPA regulation, the comparison of the 
greenhouse gas results also need not measure or include N2O 
in the before and after emission comparisons.
    (2) Compliance with heavy-duty engine greenhouse gas emission 
standards is demonstrated by complying with the CO2, 
N2O, and CH4 standards (or FELs, as applicable) 
and provisions set forth in 40 CFR 1036.108 for the engine family that 
is represented by the fuel conversion emission data engine (EDE). The 
following additional provisions apply:
    (i) If the fuel conversion CO2 measured value is lower 
than the CO2 standard (or FEL, as applicable), you have the 
option to convert the difference between the CO2 standard (or 
FEL, as applicable) and the fuel conversion CO2 measured 
value into GHG equivalents of CH4 and/or N2O, 
using 298 g/hp-hr CO2 to represent 1 g/hp-hr N2O. 
Similarly, you may use 34 g/hp-hr CO2 to represent 1 g/hp-hr 
CH4 for model year 2021 and later engines, and you may use 25 
g/hp-hr CO2 to represent 1 g/hp-hr CH4 for earlier 
engines. You may then subtract the applicable converted values from the 
fuel conversion measured values of CH4 and/or N2O 
to demonstrate compliance with the CH4 and/or N2O 
standards (or FEL, as applicable).
    (ii) Small volume conversion manufacturers may demonstrate 
compliance with N2O standards based on an engineering 
analysis.
    (iii) For conversions of engines installed in vocational vehicles 
subject to Phase 2 standards under 40 CFR 1037.105 or in tractors 
subject to Phase 2 standards under 40 CFR 1037.106, conversion 
manufacturers may omit a demonstration related to the vehicle-based 
standards, as long as they have a reasonable technical basis for 
believing that the modified vehicle continues to meet those standards.
    (3) Subject to the following exceptions and special provisions, 
compliance with greenhouse gas emission standards for heavy-duty 
vehicles subject to 40 CFR 86.1819 is demonstrated by complying with the 
N2O and CH4 standards and provisions set forth in 
40 CFR 86.1819 and the in-use CO2 exhaust emission standard 
set forth in 40 CFR 86.1819-14(b) as determined by the OEM for the 
subconfiguration that is identical to the fuel conversion emission data 
vehicle (EDV):
    (i) If the OEM complied with alternate standards for N2O 
and/or CH4, as allowed under 40 CFR 86.1819-14(c) you may 
demonstrate compliance with the same alternate standards.
    (ii) If you are unable to meet either the N2O or 
CH4 standards and your fuel conversion CO2 
measured value is lower than the in-use CO2 exhaust emission 
standard, you may also convert the difference between the in-use 
CO2 exhaust emission standard and the fuel conversion 
CO2 measured value into GHG equivalents of CH4 
and/or N2O, using 298 g CO2 to represent 1 g 
N2O. Similarly, you may use 34 g CO2 to represent 
1 g CH4.for model year 2021 and later vehicles, and you may 
use 25 g CO2 to represent 1 g CH4 for earlier 
vehicles. You may then subtract the applicable converted values from the 
fuel conversion measured values of CH4 and/or N2O 
to demonstrate compliance with the CH4 and/or N2O 
standards.
    (iii) You may alternatively comply with the greenhouse gas emission 
requirements by comparing emissions from the vehicle before and after 
the fuel conversion. This comparison must be based on FTP test results 
from the emission data vehicle (EDV) representing the pre-conversion 
test group. The sum of CO2, CH4, and 
N2O shall be calculated for pre- and post-conversion FTP test 
results, where CH4 and N2O are weighted by their 
global warming potentials as described in paragraph (b)(3)(ii) of this 
section. The post-conversion sum of these emissions must be lower than 
the pre-conversion

[[Page 327]]

greenhouse gas emission result. Calculate CO2 emissions as 
specified in 40 CFR 600.113. If we waive N2O measurement 
requirements based on a statement of compliance, disregard 
N2O for all measurements and calculations under this 
paragraph (b)(3)(iii).
    (c) Conversion systems for engines that would have qualified for 
chassis certification at the time of OEM certification may use those 
procedures, even if the OEM did not. Conversion manufacturers choosing 
this option must designate test groups using the appropriate criteria as 
described in this subpart and meet all vehicle chassis certification 
requirements set forth in 40 CFR part 86, subpart S.

[81 FR 73971, Oct. 25, 2016]



Sec.85.530  Vehicle/engine labels and packaging labels.

    (a) The following labeling requirements apply for clean alternative 
fuel conversion manufacturers to qualify for an exemption from the 
tampering prohibition:
    (1) You must make a supplemental emission control information label 
for each clean alternative fuel conversion system.
    (2) On the supplemental label you must identify the OEM vehicles/
engines for which you authorize the use of your clean alternative fuel 
conversion system, consistent with the requirements of this subpart. You 
may do this by identifying the OEM test group/engine family names and 
original model year to which your conversion is applicable as described 
in Sec.85.510(b)(1) or Sec.85.510(b)(2), Sec.85.515(b)(10)(ii), or 
Sec.85.520(b)(6)(ii). Your commercial packaging materials must also 
clearly describe this information.
    (3) You must include the following on the supplemental label:
    (i) You must state that the vehicle/engine has been equipped with a 
clean alternative fuel conversion system designed to allow it to operate 
on a fuel other than the fuel it was originally certified to operate on. 
Identify the fuel or fuels the vehicle/engine is designed to use and 
provide a unique conversion test group/conversion engine family name and 
conversion evaporative/refueling emissions family name.
    (ii) You must identify your corporate name, address, and telephone 
number.
    (iii) You must include one of the following statements that 
describes how you comply under this subpart and any applicable mileage 
or age restrictions due to how compliance was demonstrated:
    (A) ``This clean alternative fuel conversion system has been 
certified to meet EPA emission standards.''
    (B) ``Testing has shown that this clean alternative fuel conversion 
system meets EPA emission standards under the intermediate age vehicle/
engine program.''
    (C) ``This conversion system is for the purpose of use of a clean 
alternative fuel in accordance with EPA regulations and is applicable 
only to vehicles/engines that are older than 11 years or 120,000 
miles.'' (Values must be adjusted to reflect OEM useful life; useful 
life in hours should be added, if applicable).
    (iv) State the following: ``This conversion was manufactured and 
installed consistent with the principles of good engineering judgment 
and all U.S. EPA regulations.''
    (4) On the supplemental label, you must identify any original parts 
that will be removed for the conversion and any associated changes in 
maintenance specifications.
    (5) On the supplemental label, you must include the date of 
conversion and the mileage of the vehicle/engine at the time of 
conversion. Include the hours of operation instead of mileage, if 
applicable.
    (b) The supplemental emission control information label shall be 
placed in a permanent manner adjacent to the vehicle's/engine's original 
emission control information label if possible. If it is impractical to 
place the supplemental label adjacent to the original label, it must be 
placed where it will be seen by a person viewing the original label on a 
part that is needed for normal operation and does not normally need 
replacement. If the supplemental label information cannot fit on one 
label, the information can be logically split among two labels that are 
both near the original VECI or engine label.

[[Page 328]]

    (c) All information provided on clean alternative fuel conversion 
system packaging must be consistent with the required vehicle/engine 
labeling information.
    (d) Examples of all labeling and warranty information must be 
provided as part of the application for certification or notification 
process.
    (e) The marketing material and label information for a given 
conversion system must be consistent with the conversion manufacturer's 
demonstration/notification to EPA for that system.



Sec.85.535  Liability, recordkeeping, and end of year reporting.

    (a) Clean alternative fuel conversion manufacturers are liable for 
in-use performance of their conversion systems as outlined in this part.
    (b) We may conduct or require testing on any vehicles/engines as 
allowed under the Clean Air Act. This may involve confirmatory testing, 
in-use testing, and/or selective enforcement audits for clean 
alternative fuel conversion systems. Dual-fuel vehicles/engines may be 
tested when operating on any of the fuels. Mixed-fuel vehicles/engines 
may be tested on any fuel blend ratio that is expected to occur during 
normal operation.
    (c) Except for an application for certification, your actions to 
document compliance and notify us under this subpart are not a request 
for our approval. We generally do not give any formal approval short of 
issuing a certificate of conformity. However, if we learn that your 
actions fall short of full compliance with applicable requirements we 
may notify you that you have not met applicable requirements or that we 
need more information to make that determination. The exemption from the 
tampering prohibition may be void ab initio if the conversion 
manufacturer has not satisfied all of the applicable provisions of this 
subpart even if a submission to EPA has been made and the conversion 
system appears on EPA's publicly available list of compliant systems.
    (d) Clean alternative fuel conversion manufacturers must accept in-
use liability for warranty, are subject to defect reporting 
requirements, and may be required to recall any parts or systems for 
which the failure can be traced to the conversion, regardless of whether 
installation was proper or improper. The OEM shall remain liable for the 
performance of any parts or systems which retain their original function 
following conversion and are unaffected by the conversion.
    (e) Clean alternative fuel conversion manufacturers must keep 
sufficient records for five years from the date of notification or 
certification, or the date of the last conversion installation, 
whichever is later, to show that they meet applicable requirements.
    (f) Clean alternative fuel conversion manufacturers must submit an 
end of the year sales report to EPA describing the number of clean 
alternative fuel conversions by fuel type(s) and vehicle test group/
engine family by January 31 of the following year. The number of 
conversions is the sum of the calendar year intermediate age 
conversions, outside useful life conversions, and the same conversion 
model year certified clean alternative fuel conversions. The number of 
conversions will be added to any other vehicle and engine sales 
accounted for using 40 CFR 86.1838-01 or 40 CFR 86.098-14 as appropriate 
to determine small volume manufacturer or qualified small volume test 
group/engine family status.
    (g) Conversion manufacturers who market conversion systems for use 
on vehicles/engines other than the test group/engine families and 
evaporative/refueling families covered by the compliance demonstration 
and notification may be liable for a tampering violation for each 
vehicle/engine to which conversion system is misapplied.

with applicable emission standards for the in-use compliance period.



Sec.85.1403  Particulate standard for pre-1994 model year urban buses
effective at time of engine rebuild or engine replacement.

    (a) Operators of urban buses in areas described in Sec.85.1401 
shall be in compliance with one of the two programs described in 
paragraphs (b) and (c) of this section. An operator may switch between 
programs from year to year only if the operator has been in compliance 
with all the requirements of the newly chosen program at all times 
between January 1, 1995 and the date on which the operator chooses to 
switch programs.
    (b) Program 1: Performance based requirement. Program 1 requires 
that affected urban buses meet a particulate standard of 0.10 g/bhp-hr 
effective at time of engine rebuild or replacement and thereafter. The 
requirement to

[[Page 330]]

meet the 0.10 g/bhp-hr standard is automatically waived if no equipment 
has been certified that meets the 0.10 g/bhp-hr standard and has a life 
cycle cost of $7,940 or less (in 1992 dollars) for the engine being 
rebuilt. Program 1 contains fallback requirements for engines for which 
the 0.10 g/bhp-hr standard is waived. Such urban bus engines must 
receive equipment that provides a 25 percent reduction in particulate 
emissions relative to the particulate level of the original engine 
configuration. This 25 percent reduction requirement is automatically 
waived if no equipment has been certified for the engine being rebuilt 
that provides a 25 percent reduction in particulate emissions and has a 
life cycle cost $2,000 or less (in 1992 dollars). In cases where 
equipment is not available to either meet a 0.10 g/bhp-hr standard for 
less than the applicable cost ceiling or achieve a 25 percent reduction 
for less than the applicable cost ceiling, the urban bus is required to 
be equipped with an engine rebuilt to the original engine configuration 
or a configuration certified to have a particulate level lower than that 
of the original engine configuration.
    (1) Exhaust emissions from any urban bus for which this subpart is 
applicable shall not exceed a particulate standard of 0.10 grams per 
brake horsepower-hour (0.037 grams per megajoule) if equipment is 
available for the engine model of such urban bus at time of engine 
rebuild or engine replacement, as specified in paragraph (b)(1)(i) of 
this section.
    (i) Equipment is available for a particular engine model if 
equipment has been certified to a particulate standard of 0.10 grams per 
brake horsepower-hour (0.037 grams per megajoule), and the equipment for 
the engine model has been approved for certification for six months or 
more, and has a life cycle cost as determined under paragraph (b)(1)(ii) 
of this section that does not exceed the life cycle cost ceiling 
specified in paragraph (b)(1)(iii) of this section.
    (ii) The life cycle cost of equipment is equal to the sum of the 
purchase price, the installation cost, the incremental fuel cost, the 
cost of any fuel additives required, and the incremental maintenance 
cost associated with the equipment each as defined in paragraphs 
(b)(1)(ii)(A) through (b)(1)(ii)(E) of this section minus an engine 
replacement credit as defined in paragraph (b)(1)(ii)(F) of this section 
if the equipment replaces an existing engine with a new engine.
    (A) The purchase price is defined as the price at which the 
equipment (including all parts necessary to install and operate the 
equipment properly) is offered to the operator. The purchase price 
excludes reasonable shipping and handling fees and taxes, and equipment 
costs incurred by the urban bus operator for a standard rebuild.
    (B)(1) The installation cost is defined as the labor cost of 
installing the equipment on an urban bus engine, incremental to a 
standard rebuild, based on a labor rate of $35 per hour. The 
installation cost is calculated using the following equation:
[GRAPHIC] [TIFF OMITTED] TN30AU93.007

Where,

CPIR is the most recent published Consumer Price Index at 
          time of rebuild (for ``all items'' as published by the U.S. 
          Bureau of Labor Statistics).
CPI1992 is the Consumer Price Index (for ``all items'' as 
          published by the U.S. Bureau of Labor Statistics) for 1992.

    (2) The estimated number of hours necessary to install the equipment 
will be determined as part of the equipment certification process, as 
detailed in Sec.85.1407.
    (C) The incremental fuel cost is defined as the increased fuel costs 
or the fuel savings due to the use of the equipment. (By definition, 
fuel savings will

[[Page 331]]

be negative values.) The calculation of incremental fuel cost will 
depend on the type of equipment being installed.
    (1)(i) For equipment not requiring a change from on road federal 
diesel fuel, the incremental fuel cost shall be calculated as follows:
[GRAPHIC] [TIFF OMITTED] TN30AU93.008

Where,

CPIR is the most recent published Consumer Price Index at 
          time of rebuild (for ``all items'' as published by the U.S. 
          Bureau of Labor Statistics).
CPI1992 is the Consumer Price Index (for ``all items'' as 
          published by the U.S. Bureau of Labor Statistics) for 1992.

    (ii) The percent change in fuel economy will be determined as part 
of the equipment certification process, as detailed in Sec.85.1407. If 
equipment causes the fuel economy of the engine to increase, the value 
of the fuel economy % reduction in the above equation shall be a 
negative value.
    (2) For equipment requiring a fuel other than on-road federal diesel 
fuel, the incremental fuel cost shall be calculated as follows:

    (i) For equipment/alternative fuel that is being certified under 
Sec.85.1407 as available to all affected operators for less than the 
life cycle cost ceiling, the discounted lifetime mileage is 129,104 
miles. For equipment/alternative fuel that is not being certified under 
Sec.85.1407 as available to all affected operators for less than the 
life cycle cost ceiling, the discounted lifetime mileage is based on the 
age of the urban bus engine being rebuilt as specified in the following 
table:

    (ii) The cost per mile for diesel fuel is calculated based on the 
following equation:

[[Page 332]]

[GRAPHIC] [TIFF OMITTED] TN30AU93.011

    (iii) For equipment/alternative fuel that is being certified under 
Sec.85.1407 as available to all affected operators for less than the 
life cycle cost ceiling, the price of diesel fuel per gallon, excluding 
taxes, is $0.72 x (CPIR/CPI1992). For equipment/
alternative fuel that is not being certified under Sec.85.1407 as 
available to all affected operators for less than the life cycle cost 
ceiling, the price of diesel fuel per gallon, excluding taxes, is the 
price at which the operator currently purchases diesel fuel, excluding 
taxes.
    (iv) The cost per mile for alternative fuels is calculated based on 
the following equation:
[GRAPHIC] [TIFF OMITTED] TN30AU93.012

    (v) In order for the equipment/alternative fuel to be required, the 
fuel supplier must provide a contract to the urban bus operator 
specifying the cost of the fuel for the life of the engine being 
retrofitted. The contract must specify the maximum incremental cost, 
compared to the cost of diesel fuel on a per mile basis, at which the 
fuel will be sold. As part of the contract, the fuel supplier must also 
provide on-site facilities, meeting all applicable safety and fire code 
requirements, for refueling the urban bus engines being retrofitted, 
unless the operator already has sufficient refueling facilities or the 
operator agrees to use off-site refueling facilities.
    (vi) The fuel economy of the engine retrofitted with the equipment 
will be determined as part of the equipment certification process, as 
detailed in Sec.85.1407.
    (D) For equipment requiring the use of a fuel additive, the fuel 
additive cost shall be calculated as follows:
[GRAPHIC] [TIFF OMITTED] TN30AU93.013

    (1) For diesel-fueled engines, the fuel economy of the engine is 3.3 
miles per gallon. For alternatively-fueled engines, the fuel economy of 
the engine shall be determined as part of the

[[Page 333]]

equipment certification process, as detailed in Sec.85.1407.
    (2) For equipment/fuel additive that is being certified under Sec.
85.1407 as available to all affected operators for less than the life 
cycle cost ceiling, the discounted lifetime mileage is 129,104 miles. 
For equipment/fuel additive that is not being certified under Sec.
85.1407 as available to all affected operators for less than the life 
cycle cost ceiling, the discounted lifetime mileage is based on the age 
of the urban bus engine being rebuilt as specified in the following 
table:

    (3) The price of the fuel additive is the price at which the fuel 
additive supplier supplies the fuel additive to the urban bus operator. 
In order for the equipment/fuel additive to be required, the equipment/
fuel additive supplier must provide a contract to the urban bus operator 
specifying the maximum cost at which the fuel additive will be sold for 
the life of the engine being retrofitted.
    (4) The amount of fuel additive required per gallon of diesel fuel 
will be determined as part of the equipment certification process, as 
detailed in Sec.85.1407.
    (E) The incremental maintenance cost of the equipment is equal to 
the cost of the parts necessary for scheduled maintenance of the 
retrofit equipment incremental to cost of the parts necessary for 
maintenance of an original, non-retrofitted engine. The incremental 
maintenance cost will be determined as part of the equipment 
certification process, as detailed in Sec.85.1407.
    (F) For equipment which replaces an existing urban bus engine with a 
new, previously unused engine, a credit will be applied to the life 
cycle cost. The engine replacement credit will be determined as follows:

    (2) If no equipment meets the provisions of paragraph (b)(1) of this 
section for a particular model of urban bus engine, then any urban bus 
for which this subpart is applicable shall use equipment that has been 
certified to achieve at least a 25 percent reduction in particulate 
emissions from the original

[[Page 334]]

certified particulate emission level of the urban bus engine model being 
rebuilt, if such equipment is available as specified in paragraph 
(b)(2)(i) of this section. If no certification data exists for the 
emission level of the original urban bus engine configuration as 
initially certified, then other test data collected over the heavy-duty 
engine Federal Test Procedure, or an approved alternative test procedure 
prescribed under Sec.85.1414, may be considered in determining the 
percent reduction.
    (i) Equipment is available for a particular engine model if 
equipment has been certified to achieve at least a 25 percent reduction 
in particulate emissions from original levels, and the equipment for the 
engine model has been approved for certification for six months or more, 
and has a life cycle cost as determined under paragraph (b)(2)(ii) of 
this section that does not exceed the life cycle cost ceiling specified 
in paragraph (b)(2)(iii) of this section.
    (ii) The life cycle cost of equipment is equal to the sum of the 
purchase price, the installation cost, the incremental fuel cost, the 
cost of any fuel additives required, and the incremental maintenance 
cost associated with the equipment each as defined in paragraphs 
(b)(2)(ii)(A) through (b)(2)(ii)(E) of this section minus an engine 
replacement credit as defined in paragraph (b)(2)(ii)(F) of this section 
if the equipment replaces an existing engine with a new engine.
    (A) The purchase price is defined as the price at which the 
equipment (including all parts necessary to install and operate the 
equipment properly) is offered to the operator. The purchase price 
excludes reasonable shipping and handling fees and taxes, and equipment 
costs incurred by the urban bus operator for a standard rebuild.
    (B)(1) The installation cost is defined as the labor cost of 
installing the equipment on an urban bus engine, incremental to a 
standard rebuild, based on a labor rate of $35 per hour. The 
installation cost is calculated using the following equation:

          published by the U.S. Bureau of Labor Statistics) for 1992.

    (2) The estimated number of hours necessary to install the equipment 
will be determined as part of the equipment certification process, as 
detailed in Sec.85.1407.
    (C) The incremental fuel cost is defined as the increased fuel costs 
or the fuel savings due to the use of the equipment. (By definition, 
fuel savings will be negative values.) The calculation of incremental 
fuel cost will depend on the type of equipment being installed.
    (1)(i) For equipment not requiring a change from on road federal 
diesel fuel, the incremental fuel cost shall be calculated as follows:

          published by the U.S. Bureau of Labor Statistics) for 1992.

    (ii) The percent change in fuel economy will be determined as part 
of the equipment certification process, as detailed in Sec.85.1407. If 
equipment causes the fuel economy of the engine to increase, the value 
of the fuel economy % reduction in the above equation shall be a 
negative value.
    (2) For equipment requiring a fuel other than on road federal diesel 
fuel, the incremental fuel cost shall be calculated as follows:

alternative fuel that is not being certified under Sec.85.1407 as 
available to all affected operators for less than the life cycle cost 
ceiling, the price of diesel fuel per gallon, excluding taxes, is the 
price at which the operator currently purchases diesel fuel, excluding 
taxes.

    (iv) The cost per mile for alternative fuels is calculated based on 
the following equation:
[GRAPHIC] [TIFF OMITTED] TN30AU93.021

    (v) In order for the equipment/alternative fuel to be required, the 
fuel supplier must provide a contract to the urban bus operator 
specifying the cost of the fuel for the life of the engine being 
retrofitted. The contract must specify the incremental cost, compared to 
the cost of diesel fuel on a per mile basis, at which the fuel will be 
sold. As part of the contract, the fuel supplier must also provide on-
site facilities, meeting all applicable safety and fire code 
requirements, for refueling, the urban bus engines being retrofitted, 
unless the operator already has sufficient refueling facilities or the 
operator agrees to use off-site refueling facilities. The fuel supplier 
must also provide for any modifications to existing facilities that are 
necessary due to the use of the equipment/alternative fuel to meet 
applicable safety and fire code requirements.
    (vi) The fuel economy of the engine retrofitted with the equipment 
will be determined as part of the equipment certification process, as 
detailed in Sec.85.1407.
    (D) For equipment requiring the use of a fuel additive, the fuel 
additive cost shall be calculated as follows:
[GRAPHIC] [TIFF OMITTED] TN30AU93.022

    (1) For diesel-fueled engines, the fuel economy of the engine is 3.3 
miles per gallon. For alternatively-fueled engines, the fuel economy of 
the engine shall be determined as part of the equipment certification 
process, as detailed in Sec.85.1407.
    (2) For equipment/fuel additive that is being certified under Sec.
85.1407 as available to all affected operators for less than the life 
cycle cost ceiling, the discounted lifetime mileage is 129,104 miles. 
For equipment/fuel additive that is not being certified under Sec.

    (3)(i) Urban buses covered by this subpart for which no equipment is 
available under paragraphs (b)(1) or (b)(2) of this section shall be 
equipped with one of the following:
    (A) The original engine rebuilt to its original engine configuration 
as specified in paragraph (b)(3)(ii) of this section; or
    (B) An engine identical to its original engine which has been 
rebuilt to its original configuration as specified in paragraph 
(b)(3)(ii) of this section; or
    (C) An engine of a configuration with a certification PM level lower 
than the original configuration; or
    (D) A replacement engine with a particulate matter certification 
level lower than the original engine.
    (ii) All replacement or rebuilt parts shall be equivalent to the 
original equipment specifications.

[[Page 338]]

    (4) Notwithstanding paragraph (b)(3) of this section, if as of July 
1, 1996, no equipment has been certified to meet the cost ceiling 
requirements of paragraphs (b)(1) or (b)(2) of this section, then urban 
buses covered by this subpart shall be equipped with equipment that has 
been certified to achieve at least a 25 percent reduction in particulate 
emissions from the original certified particulate emission level of the 
urban bus engine model being rebuilt, provided the equipment does not 
require any of the following:
    (i) A switch from mechanical control to electronic control; or
    (ii) Installation of exhaust aftertreatment equipment; or
    (iii) The use of a fuel different from the fuel on which the engine 
currently operates.
    (c) Program 2: Averaging based program. Program 2 requires affected 
urban bus operators to meet an annual average fleet particulate 
emissions level, rather than requiring each individual rebuilt urban bus 
engine in the operator's fleet to meet a specific particulate emission 
level. Under Program 2, each affected fleet operator must reduce 
particulate emissions from its affected urban buses (i.e., 1993 and 
earlier model year urban buses) to a level low enough to meet an annual 
average target level for a fleet (TLF) for particulate emissions (in 
grams per brake horsepower-hour). The TLF is calculated for each year of 
the program beginning in 1996. During each calendar year, the average 
particulate emissions level from all of the operator's pre-1994 model 
year urban buses must be at or below the TLF for that calendar year. The 
TLF for a particular calendar year is calculated based on the Agency's 
determination of the projected emission level for each engine model in 
the operator's pre-1994 model year urban bus fleet, as specified in 
paragraph (c)(1)(iii) of this section, and based on a schedule for 
rebuilding of affected urban bus engines, as specified in paragraph 
(c)(1)(iv) of this section.
    (1) During each calendar year starting with 1996, urban bus 
operators shall be in compliance with an annual Target Level for a Fleet 
(TLF) of particulate emissions calculated using the equation defined in 
paragraph (c)(1)(i) of this section. Operators must comply with a TLF, 
rounded to two places after the decimal, until all pre-1994 urban buses 
have been retired from the operator's fleet.
    (i) An urban bus operator's annual Target Level for a Fleet (TLF) 
for a particular calendar year shall be calculated as follows:
[GRAPHIC] [TIFF OMITTED] TN30AU93.025

Where,

CY is the calendar year.
MY is the model year.
BMY is the number of urban buses of that model year in the 
          operator's fleet as of January 1, 1995, plus any urban buses 
          of that model year added to the fleet after January 1, 1995.
WPMY is the weighted average of projected particulate 
          emissions for urban buses of that model year calculated using 
          the formula in paragraph (c)(1)(ii) of this section.

    (ii) The weighted average of projected particulate emissions for 
urban buses of a particular model year is calculated using the following 
equation:

[[Page 339]]

[GRAPHIC] [TIFF OMITTED] TN30AU93.026

Where,

MY is the model year.
z is the number of different engine models in the fleet of model year 
          MY.
Bz is the number of urban buses in the operator's fleet as of 
          January 1, 1995 (including those added after January 1, 1995) 
          equipped with a specific engine model of the given model year.
Pz is the projected particulate emission level of that engine 
          model provided in paragraphs (c)(1)(iii) and (c)(1)(iv) of 
          this section.

    (iii)(A) Pre-rebuild particulate emission levels and projected post-
rebuild particulate emission levels in grams per brake horsepower-hour 
(g/bhp-hr) are based on engine type and model year and are specified in 
the following table. The appropriate particulate level, pre-rebuild or 
post-rebuild, shall be determined using the information contained in 
paragraph (c)(1)(iv) of this section.

    (2) To determine compliance under this program, the TLF, rounded to 
two places after the decimal, shall be compared with an annual Fleet 
Level Attained (FLA) of particulate emissions calculated using the 
equation defined in paragraph (c)(2)(i) of this section, and also 
rounded to two places after the decimal. At all times during a given 
calendar year, the FLA must be at or below the TLF for the same calendar 
year in order for the fleet to be in compliance.
    (i) An urban bus operator shall calculate its Fleet Level Attained 
(FLA) using the following equation:
[GRAPHIC] [TIFF OMITTED] TN30AU93.027

Where,

MY is the model year.
MY1 is the model year of the oldest urban bus in an 
          operator's fleet.
BMY is the number of urban buses of model year MY in an 
          operator's fleet, excluding those urban buses older than 
          fifteen years that meet a 0.10 grams per brake horsepower-hour 
          particulate standard.
BR is the number of 1993 and earlier model year urban buses 
          retired since January 1, 1995 that would have been less than 
          15 years old, as calculated by the model year of the urban bus 
          on December 31st of the given calendar year, but does not 
          include retired urban buses that are replaced by other 1993 
          and earlier model year urban buses.
WEMY is the weighted average of engine-specific particulate 
          emissions for urban buses in that model year in an operator's 
          fleet, excluding those urban buses older than fifteen years 
          that meet a 0.10 grams per brake horsepower-hour particulate 
          standard, calculated using the formula in paragraph (c)(2)(ii) 
          of this section.

    (ii) The weighted average of engine specific particulate emissions 
for urban buses of a particular model year, excluding those urban buses 
older than fifteen years that meet a 0.10 grams per brake horsepower-
hour particulate standard is calculated using the following equation:

[[Page 343]]

[GRAPHIC] [TIFF OMITTED] TN30AU93.028

Where,

q is the number of different engine configurations in a given model 
          year, excluding those urban buses older than fifteen years 
          that meet a 0.10 grams per brake horsepower-hour particulate 
          standard.
Bq is the number of urban buses with a specific engine 
          configuration.
Eq is the engine-specific particulate emission level for a 
          given configuration.

    (iii) The Eq shall be defined as:
    (A) The pre-rebuild level as specified in paragraph (c)(1)(iii) of 
this section in cases where an engine has not been rebuilt after January 
1, 1995 or has been rebuilt to its original configuration; or
    (B) The particulate emission level (in grams per brake horsepower-
hour) achieved after installing emission control equipment on the urban 
bus at time of rebuild, where an engine has been rebuilt using emission 
control equipment after January 1, 1995. Such particulate emission 
levels will be established by the equipment certifier during equipment 
certification; or
    (C) 0.10 grams per brake horsepower-hour (0.037 grams per megajoule) 
for urban buses covered by the provisions specified in paragraph (d)(1) 
of this section; or
    (D) The particulate emission level (in grams per brake horsepower-
hour) of the upgrade engine configuration for urban buses covered by the 
provisions specified in paragraph (d)(3) of this section; or
    (E) The particulate emission level (in grams per brake horsepower-
hour) determined by applying an additional percent reduction in 
particulate emissions to the particulate levels determined in paragraphs 
(c)(2)(iii)(A) through (c)(2)(iii)(D) of this section for those urban 
buses operating on diesel-based fuels which achieve particulate 
reductions beyond federally required diesel fuel with 0.05 weight 
percent sulfur content. Such additional percent reductions will be 
determined through certification of such diesel-based fuels as specified 
in Sec.85.1407.
    (d)(1) Operators of urban buses covered by this subpart which have 
had particulate traps installed prior to January 1, 1995, or are powered 
by an alternative fuel that significantly reduces particulate emissions 
compared to emissions from diesel fuel, may assume that such urban buses 
are operating at a PM level of 0.10 grams per brake horsepower-hour 
(0.037 grams per megajoule) for purposes of meeting the requirements set 
forth in paragraphs (b) and (c) of this section as long as such urban 
buses have engines that are properly calibrated and maintained in 
accordance with equipment manuals and instructions, and the operator has 
no reason to believe otherwise.
    (2) Any urban buses which have had particulate traps installed prior 
to January 1, 1995, or are powered by a fuel that significantly reduces 
particulate emissions compared to emissions from diesel fuel, whose 
engines have not been properly calibrated and maintained in accordance 
with equipment manuals and instructions or the operator has reason to 
believe otherwise, shall be treated as if such equipment was not 
installed for purposes of determining compliance with paragraphs (b) and 
(c) of this section.
    (3) Operators of urban buses covered by this subpart which have 
upgrade kits installed prior to January 1, 1995, may assume that such 
urban buses are operating at the PM level of the upgraded engine 
configuration for purposes of meeting the requirements set forth in 
paragraphs (b) and (c) of this section.
    (e)(1) The standard and percent emission reductions requirements set 
forth in paragraphs (b) and (c) of this section refer to exhaust emitted 
over the operating schedule set forth in paragraph (f)(2) of appendix I 
to part 86 of this

[[Page 344]]

chapter and measured and calculated in accordance with the procedures 
set forth in subpart N of part 86 of this chapter.
    (2) Equipment certifiers may also submit emission results from EPA-
approved alternative test procedures showing compliance with the 25 
percent reduction requirements of paragraphs (b) and (c) of this 
section. As required in Sec.85.1414, the equipment certifier shall 
supply information on the alternative test procedure which supports the 
certifier's claims that the alternative test procedure is typical of in-
use urban bus operation.
    (f) Every operator subject to the requirements prescribed in this 
section shall keep records of all engine rebuilds and replacements 
performed on urban buses as required in Sec.85.1404, and maintain 
evidence that their urban buses are in compliance with the requirements 
of paragraphs (b) or (c) of this section.
    (g) Operators shall affix the label provided with the equipment, 
required under Sec.85.1411(a), to the engine being rebuilt with the 
equipment.

Sec.85.1404  Maintenance of records for urban bus operators; submittal
of information; right of entry.

    (a) The operator of any urban bus for which this subpart is 
applicable shall maintain and retain the following adequately organized 
and indexed records beginning January 1, 1995. Each operator shall keep 
such records until the five year anniversary of a rebuild or until the 
engine is rebuilt again, whichever occurs first.
    (1) General records. The records required to be maintained under 
this paragraph shall consist of all purchase records, receipts, and part 
numbers for parts and components used in the rebuilding of urban bus 
engines.
    (2) Individual records. A brief history of each urban bus subject to 
the rebuild provisions prescribed under this section including the 
records and documentation required to be maintained under Sec.
85.1403(f) of this subpart.
    (3) Fuel purchase records. The records required under this paragraph 
consist of all purchase records of fuels for which the operator is 
claiming additional emission reductions under Sec.
85.1403(c)(2)(iii)(E), purchase records for fuel additives required for 
use with equipment, and purchase records for fuels, other than diesel 
fuel, which are used with dual-fueled engines.
    (b)(1) Any operator subject to the requirements under this section 
shall provide any EPA Enforcement Officer, upon presentation of 
credentials during operating hours, access to the following:
    (i) Any facility where records required to be maintained under this 
section are generated or stored.
    (ii) Any facility where engine rebuilding or replacement takes 
place.
    (2) Upon admission to any facility referred to in paragraph (b)(1) 
of this section, any EPA Enforcement Officer shall be allowed:
    (i) To inspect and make copies of records required to be maintained 
under this section.
    (ii) To inspect and photograph any urban bus and engine subject to 
the standards set forth in Sec.85.1403 of this subpart.
    (iii) To inspect and monitor any activity related to the rebuilding 
or replacement of an engine in an urban bus for which these regulations 
are applicable as described in Sec.85.1401 of this subpart.



Sec.85.1405  Applicability.

    The provisions of Sec. Sec.85.1405 through 85.1414 apply to 
retrofit/rebuild equipment which is to be installed on or used with 1993 
and earlier model year urban buses whose engines are rebuilt or replaced 
after January 1, 1995. For the purposes of Sec. Sec.85.1405 through 
85.1414, ``equipment'' includes alternative fuels and fuel additives to 
be used with urban bus engines.



Sec.85.1406  Certification.

    (a) Certification compliance shall be demonstrated as follows:
    (1) Test procedure and emission results. The emission test to be 
used is the heavy-duty engine Federal Test Procedure as set forth in the 
applicable portions of part 86 of this chapter or an approved 
alternative test procedure prescribed under Sec.85.1414. Certification 
emission testing must be carried out

[[Page 345]]

using representative production equipment as provided in paragraph (b) 
of this section. The test results must demonstrate that the retrofit/
rebuild equipment will comply with either the particulate emission 
requirements of Sec. Sec.85.1403(b)(1)(i) or 85.1403(b)(2)(i), or 
provide some level of particulate emission reduction, and will not cause 
the urban bus engine to fail to meet any applicable Federal emission 
requirements set for that engine in the applicable portions of 40 CFR 
part 86, provided the equipment is properly installed.
    (2) Emission test engine selection. (i) The test engine used must 
represent the ``worst case'' with respect to particulate emissions of 
all those engine configurations for which the retrofit/rebuild equipment 
is being certified. The worst case engine configuration shall be the 
engine configuration having the highest engine-out particulate matter 
emission levels, when properly maintained and used, prior to 
installation of the retrofit/rebuild equipment. EPA reserves the right 
to request data or information showing that the particulate emission 
reduction efficiency of the retrofit/rebuild equipment being certified 
under this paragraph, for use with more than one engine family, does not 
vary significantly among the engine families.
    (ii) The results of certification tests using the worst case engine 
selections made in this section shall be applicable for the other engine 
configurations for which the retrofit/rebuild equipment is designed.
    (iii) The worst case test engine selected for certification emission 
testing is not required to meet Federal emission standards before the 
retrofit/rebuild equipment is installed. However, each test engine shall 
have representative emissions performance that is close to the standards 
and have no obvious or suspected emission defects. Each test engine 
shall be tuned properly and set to the engine manufacturer's 
specifications before testing is performed. Any excessively worn or 
malfunctioning emission related part shall be repaired or replaced with 
a new part prior to testing.
    (iv) To demonstrate compliance with the particulate emission 
requirements of Sec.85.1403(b)(1)(i), the test engine used may be a 
new unused engine, an in-use engine that has been rebuilt previously, or 
an in-use engine that has not been rebuilt previously.
    (v) (A) To demonstrate compliance with the particulate emission 
requirements of Sec.85.1403(b)(2)(i) on engines for which particulate 
certification data exists, the test engine used may be a new unused 
engine, an in-use engine that has been rebuilt previously, or an in-use 
engine that has not been rebuilt previously.
    (B) To demonstrate compliance with the particulate emission 
requirements of Sec.85.1403(b)(2)(i) on engines for which no 
particulate certification data exists, the test engine used may be a new 
unused engine, or an in-use engine that is newly rebuilt to its original 
configuration.
    (b) Diesel test fuel. Federally required low sulfur diesel fuel 
(with a sulfur content of 0.05 weight percent) shall be used for all new 
emissions testing required to be performed for certification of

notify his immediate customers that, as of the date of the final 
determination, the equipment in question has been decertified. The 
equipment certifier shall offer to replace decertified equipment in the 
customer's inventory with certified replacement equipment or, if unable 
to do so, shall at the customer's request repurchase such inventory at a 
reasonable price. The immediate customers must stop selling the 
equipment once the certifier has notified the customer that the 
equipment has been decertified.
    (f) Notwithstanding the requirements of paragraph (e) of this 
section, equipment purchased by an urban bus operator prior to 
decertification, shall be considered certified pursuant to this subpart.



Sec.85.1414  Alternative test procedures.

    As a part of the certification process, as set forth in Sec.
85.1406, a certifier may request that the Agency approve an alternative 
test procedure, other than the heavy-duty engine Federal test procedure, 
to show compliance with the 25 percent reduction in particulate matter 
emissions as noted in Sec.85.1403(b)(2)(i). The alternative test may 
be a chassis-based test, but the alternative test shall be 
representative of in-use urban bus operation. The requestor shall supply 
relevant technical support to substantiate its claim of 
representativeness. Upon an acceptable showing that an alternative test 
is representative of in-use urban bus operation, the Agency shall 
determine whether to set such alternative test procedures through 
rulemaking. The provisions of the certification process apply to such a 
request for alternative procedures.

    Effective Date Note: At 58 FR 21386, Apr. 21, 1993, Sec.85.1414

Sec.85.1505  Final admission of certified vehicles.

    (a) A motor vehicle or engine may be finally admitted into the 
United States upon approval of the certificate holder's application to 
the Administrator. Such application shall be made either by completing 
EPA forms or by submitting the data electronically to EPA's computer, in 
accordance with EPA instructions. Such application shall contain:
    (1) The information required in Sec.85.1504(a);
    (2) Information demonstrating that the vehicle or engine has been 
modified in accordance with a valid certificate of conformity. Such 
demonstration shall be made in one of the following ways:
    (i) Through an attestation by the certificate holder that the 
vehicle or engine has been modified in accordance with the provisions of 
the certificate holder's certificate, and presentation

[[Page 356]]

to EPA of a statement by the appropriate OEM that the OEM will provide 
to the certificate holder and to EPA information concerning running 
changes to the vehicle or engine described in the certificate holder's 
application for certification, and actual receipt by EPA of notification 
by the certificate holder of any running changes already implemented by 
the OEM at the time of application and their effect on emissions; or
    (ii) Through an attestation by the certificate holder that the 
vehicle or engine has been modified in accordance with the provisions of 
the certificate holder's certificate of conformity and that the 
certificate holder has conducted an FTP test, at a laboratory within the 
United States, that demonstrates compliance with Federal emission 
requirements on every third vehicle or third engine imported under that 
certificate within 120 days of entry, with sequencing of the tests to be 
determined by the date of importation of each vehicle or engine. Should 
the certificate holder have exceeded a threshold of 300 vehicles or 
engines imported under the certificate without adjustments or other 
changes in accordance with paragraph (a)(3) of this section, the amount 
of required FTP testing may be reduced to every fifth vehicle or engine. 
In order to make a demonstration under paragraph (a)(2)(i) of this 
section, a certificate holder must have received permission from the 
Administrator to do so;
    (3) The results of every FTP test which the certificate holder 
conducted on the vehicle or engine. Should a subject vehicle or engine 
have failed an FTP at any time, the following procedures are applicable:
    (i) The certificate holder may either:
    (A) Conduct one FTP retest that involves no adjustment of the 
vehicle or engine from the previous test (e.g., adjusting the RPM, 
timing, air-to-fuel ratio, etc.) other than adjustments to adjustable 
parameters that, upon inspection, were found to be out of tolerance. 
When such an allowable adjustment is made, the parameter may be reset 
only to the specified (i.e., nominal) value (and not any other value 
within the tolerance band); or
    (B) Initiate a change in production (running change) under the 
provisions of 40 CFR 86.084-14(c)(13) or 86.1842-01, as applicable, that 
causes the vehicle to meet Federal emission requirements.
    (ii) If the certificate holder chooses to retest in accordance with 
paragraph (a)(3)(i)(A) of this section:
    (A) Such retests must be completed no later than five working days 
subsequent to the first FTP test;
    (B) Should the subject vehicle or engine fail the second FTP, then 
the certificate holder must initiate a change in production (a running 
change) under the provisions of 40 CFR 86.084-14(c)(13) or 86.1842-01, 
as applicable, that causes the vehicle to meet Federal emission 
requirements.
    (iii) If the certificate holder chooses to initiate a change in 
production (a running change) under the provisions of 40 CFR 86.084-
14(c)(13) or 86.1842-01 as applicable, that causes the vehicle to meet 
Federal requirements, changes involving adjustments of adjustable 
vehicle parameters (e.g., adjusting the RPM, timing, air/fuel ratio) 
must be changes in the specified (i.e., nominal) values to be deemed 
acceptable by EPA.
    (iv) Production changes made in accordance with this section must be 
implemented on all subsequent vehicles or engines imported under the 
certificate after the date of importation of the vehicle or engine which 
gave rise to the production change.
    (v) Commencing with the first vehicle or engine receiving the 
running change, every third vehicle or engine imported under the 
certificate must be FTP tested to demonstrate compliance with Federal 
emission requirements until, as in paragraph (a)(2)(ii) of this section, 
a threshold of 300 vehicles or engines imported under the certificate is 
exceeded, at which time the amount of required FTP testing may be 
reduced to every fifth vehicle or engine.
    (vi) Reports concerning these running changes shall be made to both 
the Manufacturers Operations and Certification Divisions of EPA within 
ten working days of initiation of the running change. The cause of any 
failure of an FTP shall be identified, if known;

[[Page 357]]

    (4) The applicable deterioration factor;
    (5) The FTP results adjusted by the deterioration factor;
    (6) Such other information that may be specified by applicable 
regulations or on the certificate under which the vehicle or engine has 
been modified in order to assure compliance with requirements of the 
Act;
    (7) All information required under Sec.85.1510;
    (8) An attestation by the certificate holder that the certificate 
holder is responsible for the vehicle's or engine's compliance with 
Federal emission requirements, regardless of whether the certificate 
holder owns the vehicle or engine imported under this section;
    (9) The name, address and telephone number of the person who the 
certificate holder prefers to receive EPA notification under Sec.
85.1505(c); and
    (10) Such other information as is deemed necessary by the 
Administrator.
    (b) EPA approval for final admission of a vehicle or engine under 
this section shall be presumed not to have been granted if a vehicle has 
not been properly modified to be in conformity in all material respects 
with the description in the application for certification or has not 
complied with the provisions of Sec.85.1505(a)(2) or its final FTP 
results, adjusted by the deterioration factor, if applicable, do not 
comply with applicable emission standards.
    (c) Except as provided in Sec.85.1505(b), EPA approval for final 
admission of a vehicle or engine under this section shall be presumed to 
have been granted should the certificate holder not have received oral 
or written notice from EPA to the contrary within 15 working days of the 
date of EPA's receipt of the certificate holder's application under 
Sec.85.1505(a). Such EPA notice shall be made to an employee of the 
certificate holder. If application is made on EPA forms, the date on a 
certified mail receipt shall be deemed to be the official date of 
notification to EPA. If application is made by submitting the data 
electronically, the date of acceptance by EPA's computer shall be deemed 
to be the official date of notification to EPA. During this 15 working 
day period, the vehicle or engine must be stored at a location where the 
Administrator will have reasonable access to the vehicle or engine for 
his/her inspection.

    Effective Date Note: At 86 FR 34363, June 29, 2021, Sec.85.1511 
was amended, effective July 29, 2021.



Sec.85.1512  Admission of catalyst and O2 sensor-equipped vehicles.

    (a)(1) Notwithstanding other provisions of this subpart, any person 
may conditionally import a vehicle which:
    (i) Was covered by a certificate of conformity at the time of 
original manufacture or had previously been admitted into the United 
States under Sec.85.1505 or Sec.85.1509 (after June 30, 1988).
    (ii) Was certified, or previously admitted under Sec.85.1505 or 
Sec.85.1509 (after June 30, 1988), with a catalyst emission control 
system and/or O2 sensor;
    (iii) Is labeled in accordance with 40 CFR part 86, subpart A or 
subpart S, or, where applicable, Sec.85.1510(c); and
    (iv) Has been driven outside the United States, Canada and Mexico or 
such other countries as EPA may designate.
    (2) Such vehicle must be entered under bond pursuant to 19 CFR 12.73 
unless it is included in a catalyst and O2 sensor control 
program approved by the Administrator upon such terms as may be deemed 
appropriate. Catalyst and O2 sensor programs conducted by 
manufacturers may be approved each model year.
    (b) For the purpose of this section, ``catalyst and O2 
sensor control program'' means a program instituted and maintained by a 
manufacturer, or any U.S. Government Agency for the purpose of 
preservation, replacement, or initial installation of catalytic 
converters and cleaning and/or replacement of O2 sensors and, 
if applicable, restricted fuel filler inlets.
    (c) For the purpose of this section, ``driven outside the United 
States, Canada and Mexico'' does not include mileage accumulated on 
vehicles solely under the control of manufacturers of new motor vehicles 
or engines for the purpose of vehicle testing and adjustment, and 
preparation for shipment to the United States.
    (d) Vehicles conditionally imported pursuant to this section and 
under bond must be modified in accordance with the certificate of 
conformity applicable at the time of manufacture. In the case of 
vehicles previously imported under Sec.85.1509 or Sec.85.1504 (prior 
to July 1, 1988), the replacement catalyst and O2 sensor, if 
applicable, must be equivalent (in terms of emission reduction) to the 
original catalyst and O2 sensor. Such vehicles may be granted 
final admission upon application to the Administrator, on forms 
specified by the Administrator. Such application shall contain the 
information required in Sec.85.1504(a)(1) (i) through (v) and shall 
contain both an attestation by a qualified mechanic that the catalyst 
has been replaced and the O2 sensor has been replaced, if 
necessary, and that both parts are functioning properly, and a copy of 
the invoice for parts and labor.

vehicles or engines under Sec.85.1509 in the future and be placed on a 
list of certificate holders ineligible to import vehicles or engines 
under the provisions of Sec.85.1509.
    (2) Grounds for the actions described in paragraph (e)(1) of this 
section shall include, but not be limited to, the following:
    (i) Action or inaction by the certificate holder or the laboratory 
performing the FTP on behalf of the certificate holder which results in 
fraudulent, deceitful or grossly inaccurate representation of any fact 
or condition which affects a vehicle's or engine's eligibility for

    (ii) Failure of a significant number of vehicles or engines imported 
to comply with Federal emission requirements upon EPA inspection or 
retest; or
    (iii) Failure by a certificate holder to comply with requirements of 
this subpart.
    (3) The following procedures govern any decision to suspend, revoke, 
or refuse to issue certificates under this subpart:
    (i) When grounds appear to exist for the actions described in 
paragraph (e)(1) of this section, the Administrator shall notify the 
certificate holder in writing of any intended suspension or revocation 
of a certificate, proposed ineligibility to apply for new certificates, 
or intended suspension of eligibility to conduct modification/testing 
under Sec.85.1509, and the grounds for such action.
    (ii) Except as provided by paragraph (e)(3)(iv) of this section, the 
certificate holder must take the following actions before the 
Administrator will consider withdrawing notice of intent to suspend or 
revoke the certificate holder's certificate or the certificate holder's 
eligibility to perform modification/testing under Sec.85.1509:
    (A) Submit a written report to the Administrator which identifies 
the reason for the noncompliance of the vehicle or engines, describes 
the proposed remedy, including a description of any proposed quality 
control and/or quality assurance measures to be taken by the certificate 
holder to prevent the future occurrence of the problem, and states the 
date on which the remedies will be implemented; or
    (B) Demonstrate that the vehicles or engines do in fact comply with 
applicable regulations in this chapter by retesting such vehicles or 
engines in accordance with the FTP.
    (iii) A certificate holder may request within 15 calendar days of 
the Administrator's notice of intent to suspend or revoke a certificate 
holder's eligibility to perform modification/testing or certificate that 
the Administrator grant such certificate holder a hearing:
    (A) As to whether the tests have been properly conducted,
    (B) As to any substantial factual issue raised by the 
Administrator's proposed action.

[[Page 367]]

    (iv) If, after the Administrator notifies a certificate holder of 
his/her intent to suspend or revoke a certificate holder's certificate 
of conformity or its eligibility to perform modification/testing under 
Sec.85.1509 and prior to any final suspension or revocation, the 
certificate holder demonstrates to the Administrator's satisfaction that 
the decision to initiate suspension or revocation of the certificate or 
eligibility to perform modification/testing under Sec.85.1509 was 
based on erroneous information, the Administrator will withdraw the 
notice of intent.
    (4) Hearings on suspensions and revocations of certificates of 
conformity or of eligibility to perform modification/testing under Sec.
85.1509 shall be held in accordance with 40 CFR part 1068, subpart G.
    (5) When a hearing is requested under this paragraph and it clearly 
appears from the data or other information contained in the request for 
a hearing, or submitted at the hearing, that there is no genuine and 
substantial question of fact with respect to the issue of whether the 
certificate holder failed to comply with this subpart, the Administrator 
will enter an order denying the request for a hearing, or terminating 
the hearing, and suspending or revoking the certificate of conformity or 
the certificate holder's eligibility to perform modification/testing 
under Sec.85.1509.
    (6) In lieu of requesting a hearing under paragraph (e)(3)(iii) of 
this section, a certificate holder may respond in writing to EPA's 
charges in the notice of intent to suspend or revoke. Such a written 
response must be received by EPA within 30 days of the date of EPA's 
notice of intent. No final decision to suspend or revoke will be made 
before that time.

submitted pursuant to this subpart is entitled to confidential treatment 
as provided by 40 CFR part 2, subpart B.
    (b) Any claim of confidentiality must accompany the information at 
the time it is submitted to EPA.
    (c) To assert that information submitted pursuant to this subpart is 
confidential, an importer must indicate clearly the items of information 
claimed confidential by marking, circling, bracketing, stamping, or 
otherwise specifying the confidential information. Furthermore, EPA 
requests, but does not require, that the submitter also provide a second 
copy of its submittal from which all confidential information has been 
deleted. If a need arises to publicly release nonconfidential

Sec.85.1515  Emission standards and test procedures applicable to
imported nonconforming motor vehicles and motor vehicle engines.

    (a) Notwithstanding any other requirements of this subpart, any 
motor vehicle or motor vehicle engine conditionally imported pursuant to 
Sec.85.1505 or Sec.85.1509 and required to be emission tested shall 
be tested using the FCT at 40 CFR part 86 applicable to current model 
year motor vehicles and motor vehicle engines at the time of testing or 
reduced testing requirements as follows:
    (1) ICIs are eligible for reduced testing under this paragraph (a) 
subject to the following conditions:
    (i) The OEM must have a valid certificate of conformity covering the 
vehicle.

[[Page 368]]

    (ii) The vehicle must be in its original configuration as certified 
by the OEM. This applies for all emission-related components, including 
the electronic control module, engine calibrations, and all evaporative/
refueling control hardware. It also applies for OBD software and 
hardware, including all sensors and actuators.
    (iii) The vehicle modified as described in paragraph (a)(1)(ii) of 
this section must fully comply with all applicable emission standards 
and requirements.
    (iv) Vehicles must have the proper OBD systems installed and 
operating. When faults are present, the ICI must test and verify the 
system's ability to find the faults (such as disconnected components), 
set codes, and illuminate the light, and set readiness codes as 
appropriate for each vehicle. When no fault is present, the ICI must 
verify that after sufficient prep driving (typically one FTP test 
cycle), all OBD readiness codes are set and the OBD system does not 
indicate a malfunction (i.e., no codes set and no light illuminated).
    (v) The ICI may not modify more than 300 vehicles in any given model 
year using reduced testing provisions in this paragraph (a).
    (vi) The ICI must state in the application for certification that it 
will meet all the conditions in this paragraph (a)(1).
    (2) The following provisions allow for ICIs to certify vehicles with 
reduced testing:
    (i) In addition to the test waivers specified in 40 CFR 86.1829, you 
may provide a statement in the application for certification, supported 
by engineering analysis, that vehicles comply with any of the following 
standards that apply instead of submitting test data:
    (A) Cold temperature CO and NMHC emission standards specified in 40 
CFR 86.1811.
    (B) SFTP emission standards specified in 40 CFR 86.1811 and 86.1816 
for all pollutants.
    (C) For anything other than diesel-fueled vehicles, PM emission 
standards specified in 40 CFR 86.1811 and 86.1816.
    (D) Any running loss, refueling, spitback, bleed emissions, and leak 
standards specified in 40 CFR part 86, subparts A and S.
    (ii) You must perform testing and submit test data as follows to 
demonstrate compliance with emission standards:
    (A) Exhaust and fuel economy tests. You must measure emissions over 
the FTP driving cycle and the highway fuel economy driving cycle as 
specified in 40 CFR 600.109 to meet the fuel economy requirements in 40 
CFR part 600 and demonstrate compliance with the exhaust emission 
standards in 40 CFR part 86 (other than PM). Measure exhaust emissions 
and fuel economy with the same test procedures used by the original 
manufacturer to test the vehicle for certification. However, you must 
use an electric dynamometer meeting the requirements of Sec.86.108 or 
40 CFR part 1066, subpart B, unless we approve a different dynamometer 
based on excessive compliance costs. If you certify based on testing 
with a different dynamometer, you must state in the application for 
certification that all vehicles in the emission family will comply with 
emission standards if tested on an electric dynamometer.
    (B) Evaporative emission test. You may measure evaporative emissions 
as specified in this paragraph (a)(2)(ii)(B) to demonstrate compliance 
with the evaporative emission standards in 40 CFR part 86 instead of the 
otherwise specified procedures. Use measurement equipment for 
evaporative measurements specified in 40 CFR part 86, subpart B, except 
that the evaporative emission enclosure does not need to accommodate 
varying ambient temperatures. The evaporative measurement procedure is 
integral to the procedure for measuring exhaust emissions over the FTP 
driving cycle as described in paragraph (a)(ii)(2)(A) of this section. 
Perform canister preconditioning using the same procedure used by the 
original manufacturer to certify the vehicle; perform this canister 
loading before the initial preconditioning drive. Perform a diurnal 
emission test at the end of the stabilization period before the exhaust 
emission test by heating the fuel from 60 to 84 [deg]F, either by 
exposing the vehicle to increasing ambient temperatures or by applying 
heat directly to the fuel tank. Measure hot

[[Page 369]]

soak emissions as described in 40 CFR 86.138-96(k). We may approve 
alternative measurement procedures that are equivalent to or more 
stringent than the specified procedures if the specified procedures are 
impractical for particular vehicle models or measurement facilities. The 
sum of the measured diurnal and hot soak values must meet the 
appropriate emission standard as specified in this section.
    (b) The emission standards applicable to nonconforming light-duty 
vehicles and light-duty trucks imported pursuant to this subpart are 
outlined in tables 1 and 2 of this section, respectively. The useful 
life as specified in tables 1 and 2 of this section is applicable to 
imported light-duty vehicles and light-duty trucks, respectively.
    (c)(1) Nonconforming motor vehicles or motor vehicle engines of 1994 
OP year and later conditionally imported pursuant to Sec.85.1505 or 
Sec.85.1509 shall meet all of the emission standards specified in 40 
CFR part 86 for the OP year of the vehicle or motor vehicle engine. The 
useful life specified in 40 CFR part 86 for the OP year of the motor 
vehicle or motor vehicle engine is applicable where useful life is not 
designated in this subpart.
    (2)(i) Nonconforming light-duty vehicles and light light-duty trucks 
(LDV/LLDTs) originally manufactured in OP years 2004, 2005 or 2006 must 
meet the FTP exhaust emission standards of bin 9 in Tables S04-1 and 
S04-2 in 40 CFR 86.1811-04 and the evaporative emission standards for 
light-duty vehicles and light light-duty trucks specified in 40 CFR 
86.1811-01(e)(5).
    (ii) Nonconforming LDT3s and LDT4s (HLDTs) and medium-duty passenger 
vehicles (MDPVs) originally manufactured in OP years 2004 through 2006 
must meet the FTP exhaust emission standards of bin 10 in Tables S04-1 
and S04-2 in 40 CFR 86.1811-04 and the applicable evaporative emission 
standards specified in 40 CFR 86.1811-04(e)(5). For 2004 OP year HLDTs 
and MDPVs where modifications commence on the first vehicle of a test 
group before December 21, 2003, this requirement does not apply to the 
2004 OP year. ICIs opting to bring all of their 2004 OP year HLDTs and 
MDPVs into compliance with the exhaust emission standards of bin 10 in 
Tables S04-1 and S04-2 in 40 CFR 86.1811-04, may use the optional higher 
NMOG values for their 2004-2006 OP year LDT2s and 2004-2008 LDT4s.
    (iii) Nonconforming LDT3s and LDT4s (HLDTs) and medium-duty 
passenger vehicles (MDPVs) originally manufactured in OP years 2007 and 
2008 must meet the FTP exhaust emission standards of bin 8 in Tables 
S04-1 and S04-2 in 40 CFR 86.1811-04 and the applicable evaporative 
standards specified in 40 CFR 86.1811-04(e)(5).
    (iv) Nonconforming LDV/LLDTs originally manufactured in OP years 
2007 through 2021 and nonconforming HLDTs and MDPVs originally 
manufactured in OP year 2009 through 2021 must meet the FTP exhaust 
emission standards of bin 5 in Tables S04-1 and S04-2 in 40 CFR 86.1811-
04, and the evaporative standards specified in 40 CFR 86.1811-04(e)(1) 
through (4).
    (v) ICIs are exempt from the Tier 2 and the interim non-Tier2 phase-
in intermediate percentage requirements for exhaust, evaporative, and 
refueling emissions described in 40 CFR 86.1811-04.
    (vi) In cases where multiple standards exist in a given model year 
in 40 CFR part 86 due to phase-in requirements of new standards, the 
applicable standards for motor vehicle engines required to be certified 
to engine-based standards are the least stringent standards applicable 
to the engine type for the OP year.
    (vii) Nonconforming LDV/LLDTs originally manufactured in OP years 
2009 through 2021 must meet the evaporative emission standards in Table 
S09-1 in 40 CFR 86.1811-09(e). However, LDV/LLDTs originally 
manufactured in OP years 2009 and 2010 and imported by ICIs who qualify 
as small-volume manufacturers as defined in 40 CFR 86.1838-01 are exempt 
from the LDV/LLDT evaporative emission standards in Table S09-1 in 40 
CFR 86.1811-09(e), but must comply with the Tier 2 evaporative emission 
standards in Table S04-3 in 40 CFR 86.1811-04(e).
    (viii) Nonconforming HLDTs and MDPVs originally manufactured in OP 
years 2010 through 2021 must meet the evaporative emission standards in 
Table S09-1 in 40 CFR 86.1811-09(e).

[[Page 370]]

However, HLDTs and MDPVs originally manufactured in OP years 2010 and 
2011 and imported by ICIs, who qualify as small-volume manufacturers as 
defined in 40 CFR 86.1838-01, are exempt from the HLDTs and MDPVs 
evaporative emission standards in Table S09-1 in 40 CFR 86.1811-09(e), 
but must comply with the Tier 2 evaporative emission standards in Table 
S04-3 in 40 CFR 86.1811-04(e).
    (ix) Nonconforming LDVs, LDTs, MDPVs, and complete heavy-duty 
vehicles at or below 14,000 pounds GVWR originally manufactured in OP 
years 2022 and later must meet the Tier 3 exhaust and evaporative 
emission standards in 40 CFR 86.1811-17, 86.1813-17, and 86.1816-18.
    (3)(i) As an option to the requirements of paragraph (c)(2) of this 
section, independent commercial importers may elect to meet lower bins 
in Tables S04-1 and S04-2 of 40 CFR 86.1811-04 than specified in 
paragraph (c)(2) of this section and bank or sell NOX credits 
as permitted in 40 CFR 86.1860-04 and 40 CFR 86.1861-04. An ICI may not 
meet higher bins in Tables S04-1 and S04-2 of 40 CFR 86.1811-04 than 
specified in paragraph (c)(2) of this section unless it demonstrates to 
the Administrator at the time of certification that it has obtained 
appropriate and sufficient NOX credits from another 
manufacturer, or has generated them in a previous model year or in the 
current model year and not transferred them to another manufacturer or 
used them to address other vehicles as permitted in 40 CFR 86.1860-04 
and 40 CFR 86.1861-04.
    (ii) Where an ICI desires to obtain a certificate of conformity 
using a bin higher than specified in paragraph (c)(2) of this section, 
but does not have sufficient credits to cover vehicles produced under 
such certificate, the Administrator may issue such certificate if the 
ICI has also obtained a certificate of conformity for vehicles certified 
using a bin lower than that required under paragraph (c)(2) of this 
section. The ICI may then produce vehicles to the higher bin only to the 
extent that it has generated sufficient credits from vehicles certified 
to the lower bin during the same model year.
    (4) [Reserved]
    (5) Except for the situation where an ICI desires to bank, sell or 
use NOX credits as described in paragraph (c)(3) of this 
section, the requirements of 40 CFR 86.1811-04 related to fleet average 
NOX standards and requirements to comply with such standards 
do not apply to vehicles modified under this subpart.
    (6) ICIs using bins higher than those specified in paragraph (c)(2) 
of this section must monitor their production so that they do not 
produce more vehicles certified to the standards of such bins than their 
available credits can cover. ICIs must not have a credit deficit at the 
end of a model year and are not permitted to use the deficit 
carryforward provisions provided in 40 CFR 86.1860-04(e).
    (7) The Administrator may condition the certificates of conformity 
issued to ICIs as necessary to ensure that vehicles subject to paragraph 
(c) of this section comply with the appropriate average NOX 
standard for each model year.
    (8)(i) Nonconforming LDV/LLDTs originally manufactured in OP years 
2010 and later must meet the cold temperature NHMC emission standards in 
Table S10-1 in 40 CFR 86.1811-10(g).
    (ii) Nonconforming HLDTs and MDPVs originally manufactured in OP 
years 2012 and later must meet the cold temperature NHMC emission 
standards in Table S10-1 in 40 CFR 86.1811-10(g).
    (iii) ICIs, which qualify as small-volume manufacturers, are exempt 
from the cold temperature NMHC phase-in intermediate percentage 
requirements described in 40 CFR 86.1811-10(g)(3). See 40 CFR 86.1811-
04(k)(5)(vi) and (vii).
    (iv) As an alternative to the requirements of paragraphs (c)(8)(i) 
and (ii) of this section, ICIs may elect to meet a cold temperature NMHC 
family emission level below the cold temperature NMHC fleet average 
standards specified in Table S10-1 of 40 CFR 86.1811-10 and bank or sell 
credits as permitted in 40 CFR 86.1864-10. An ICI may not meet a higher 
cold temperature NMHC family emission level than the fleet average 
standards in Table S10-1 of 40 CFR 86.1811-10 as specified in paragraphs 
(c)(8)(i) and (ii) of this section, unless it demonstrates to the 
Administrator at the time of certification that it has

[[Page 371]]

obtained appropriate and sufficient NMHC credits from another 
manufacturer, or has generated them in a previous model year or in the 
current model year and not traded them to another manufacturer or used 
them to address other vehicles as permitted in 40 CFR 86.1864-10.
    (v) Where an ICI desires to obtain a certificate of conformity using 
a higher cold temperature NMHC family emission level than specified in 
paragraphs (c)(8)(i) and (ii) of this section, but does not have 
sufficient credits to cover vehicles imported under such certificate, 
the Administrator may issue such certificate if the ICI has also 
obtained a certificate of conformity for vehicles certified using a cold 
temperature NMHC family emission level lower than that required under 
paragraphs (c)(8)(i) and (ii) of this section. The ICI may then import 
vehicles to the higher cold temperature NMHC family emission level only 
to the extent that it has generated sufficient credits from vehicles 
certified to a family emission level lower than the cold temperature 
NMHC fleet average standard during the same model year.
    (vi) ICIs using cold temperature NMHC family emission levels higher 
than the cold temperature NMHC fleet average standards specified in 
paragraphs (c)(8)(i) and (ii) of this section must monitor their imports 
so that they do not import more vehicles certified to such family 
emission levels than their available credits can cover. ICIs must not 
have a credit deficit at the end of a model year and are not permitted 
to use the deficit carryforward provisions provided in 40 CFR 86.1864-
10.
    (vii) The Administrator may condition the certificates of conformity 
issued to ICIs as necessary to ensure that vehicles subject to this 
paragraph (c)(8) comply with the applicable cold temperature NMHC fleet 
average standard for each model year.
    (d) Except as provided in paragraph (c) of this section, ICI's must 
not participate in emission-related programs for emissions averaging, 
banking and trading, or nonconformance penalties.

\1\ Diesel particulate standards apply only to diesel fueled light-duty trucks. Evaporative hydrocarbon standards apply only to non-diesel fueled light-
  duty trucks. For alternative fueled light-duty trucks, the evaporative hydrocarbon standard is interpreted as organic material hydrocarbon equivalent
  grams carbon per test, as applicable.
\2\ No crankcase emissions shall be discharged into the ambient atmosphere from any non-diesel fueled light-duty truck.
\3\ A carbon monoxide standard of 0.50% of exhaust flow at curb idle is applicable to all 1984 and later model year light-duty trucks sold to, or owned
  by, an importer for principal use at other than a designated high-altitude location. This requirement is effective for light-duty trucks sold to, or
  owned by an importer for principal use at a designated high-altitude location beginning with the 1988 model year.
\4\ All 1982 OP year and later light-duty trucks sold to, or owned by, an importer for principal use at a designated high-altitude location shall meet
  high-altitude emission standards according to the requirements specified in 40 CFR part 86 for current model year light-duty trucks at the time of
  testing.
\5\ Standards in parentheses apply to motor vehicles sold to, or owned by, an importer for principal use at a designated high-altitude location. These
  standards must be met at high-altitude according to the procedures specified in 40 CFR part 86 for current model year motor vehicles at the time of
  testing.
\6\ The oxides of nitrogen standard of 1.2 gpm applies to light-duty trucks at or below 3,750 pounds loaded vehicle weight and at or below 6,000 pounds
  GVWR. The 1.7 gpm standard applies to light-duty trucks above 3,750 pound loaded vehicle weight and at or below 6,000 pounds GVWR; the 2.3 gpm
  standard applies to light-duty trucks above 6,000 pounds GVWR.

Sec.85.1703  Definition of motor vehicle.

    (a) For the purpose of determining the applicability of section 
216(2), a vehicle which is self-propelled and capable of transporting a 
person or persons or any material or any permanently or temporarily 
affixed apparatus shall be deemed a motor vehicle, unless any one or 
more of the criteria set forth below are met, in which case the vehicle 
shall be deemed not a motor vehicle:
    (1) The vehicle cannot exceed a maximum speed of 25 miles per hour 
over level, paved surfaces; or
    (2) The vehicle lacks features customarily associated with safe and 
practical street or highway use, such features including, but not being 
limited to, a reverse gear (except in the case of motorcycles), a 
differential, or safety features required by state and/or federal law; 
or
    (3) The vehicle exhibits features which render its use on a street 
or highway unsafe, impractical, or highly unlikely, such features 
including, but not being limited to, tracked road contact means, an 
inordinate size, or features ordinarily associated with military combat 
or tactical vehicles such as armor and/or weaponry.
    (b) Note that, in applying the criterion in paragraph (a)(2) of this 
section, vehicles that are clearly intended for operation on highways 
are motor vehicles. Absence of a particular safety feature is relevant 
only when absence of that feature would prevent operation on highways.

[45 FR 13733, Mar. 3, 1980, as amended at 47 FR 30484, July 14, 1982]



Sec.85.1705  Testing exemption.

    (a) Any person requesting a testing exemption must demonstrate the 
following:

[[Page 374]]

    (1) That the proposed test program has a purpose which constitutes 
an appropriate basis for an exemption in accordance with section 
203(b)(1);
    (2) That the proposed test program necessitates the granting of an 
exemption;
    (3) That the proposed test program exhibits reasonableness in scope; 
and
    (4) That the proposed test program exhibits a degree of control 
consonant with the purpose of the program and the Environmental 
Protection Agency's (hereafter EPA) monitoring requirements. Paragraphs 
(b), (c), (d), and (e) of this section describe what constitutes a 
sufficient demonstration for each of the four above identified elements.
    (b) With respect to the purpose of the proposed test program, an 
appropriate purpose is one which is consistent with one or more of the 
bases for exemption set forth under section 203(b)(1), namely, research, 
investigations, studies, demonstrations, or training, but not including 
national security. A concise statement of purpose is a required item of 
information.
    (c) With respect to the necessity that an exemption be granted, 
necessity arises from an inability to achieve the stated purpose in a 
practicable manner without performing or causing to be performed one or 
more of the prohibited acts under section 203(a). In appropriate 
circumstances time constraints may be a sufficient basis for necessity, 
but the cost of certification alone, in the absence of extraordinary 
circumstances, is not a basis for necessity.
    (d) With respect to reasonableness, a test program must exhibit a 
duration of reasonable length and affect a reasonable number of vehicles 
or engines. In this regard, required items of information include:
    (1) An estimate of the program's duration;
    (2) The maximum number of vehicles or engines involved; and
    (e) With respect to control, the test program must incorporate 
procedures consistent with the purpose of the test and be capable of 
affording EPA monitoring capability. As a minimum, required items of 
information include:
    (1) The technical nature of the test;
    (2) The site of the test;
    (3) The time or mileage duration of the test;
    (4) The ownership arrangement with regard to the vehicles or engines 
involved in the test;
    (5) The intended final disposition of the vehicles or engines;
    (6) The manner in which vehicle identification numbers or the engine 
serial numbers will be identified, recorded, and made available; and
    (7) The means or procedure whereby test results will be recorded.
    (f) A manufacturer of new motor vehicles or new motor vehicle 
engines may request a testing exemption to cover any vehicles and/or 
engines intended for use in test programs planned or anticipated over 
the course of a subsequent one-year period. Unless otherwise required by 
the Director, Manufacturers Operations Division, a manufacturer 
requesting such an exemption need only furnish the information required 
by paragraphs (a)(1) and (d)(2) of this section along with a description 
of the recordkeeping and control procedures that will be employed to 
assure that the vehicles and/or engines are used for purposes consistent 
with section 203(b)(1).

Sec.85.1706  Pre-certification exemption.

    (a) Except as provided in paragraph (b) of this section, any pre-
certification vehicle or pre-certification vehicle engine, as defined by 
Sec.85.1702(a) (3) or (4), is exempt from section 203(a), without 
application, if the manufacturer complies with the following terms and 
conditions:
    (1) The manufacturer shall create, maintain, and make available at 
reasonable times for review or copying by appropriate EPA employees 
records which provide each vehicle identification or engine serial 
number, indicate the use of the vehicle or engine on exempt status and 
indicate the final disposition of any vehicle or engine removed from 
exempt status; and
    (2) Unless the requirement is waived or an alternative procedure is 
approved by the Director, Manufacturers Operations Division, the 
manufacturer shall

[[Page 375]]

permanently affix to each vehicle or engine on exempt status in a 
readily visible portion of the engine compartment (on a readily visible 
portion of a heavy-duty engine or in a readily accessible position on a 
motorcycle) a label which cannot be removed without destruction or 
defacement and which states in the English language, in block letters 
and numerals of a color that contrasts with the background of the label, 
the following information:
    (i) The label heading: Emission Control Information;
    (ii) Full corporate name and trademark of manufacturer;
    (iii) Engine displacement, engine family identification and model 
year of vehicle or engine; or person or office to be contacted for 
further information about the vehicle or engine;
    (iv) The statement: THIS VEHICLE OR ENGINE IS EXEMPT FROM THE 
PROHIBITIONS OF SECTIONS 203(a)(1), (3) and (4) OF THE CLEAN AIR ACT, AS 
AMENDED.
    (3) No provision of paragraph (a)(2) of this section shall prevent a 
manufacturer from including any other information it desires on the 
label.
    (b) Any manufacturer that desires a pre-certification exemption and 
is in the business of importing, modifying or testing uncertified 
vehicles for resale under the provisions of 40 CFR 85.1501 through 
85.1515, must send the request to the Designated Compliance Officer as 
specified in 40 CFR 1068.30. The Designated Compliance Officer may 
require such manufacturers to submit information regarding the general 
nature of the fleet activities, the number of vehicles involved, and a 
demonstration that adequate record-keeping procedures for control 
purposes will be employed.

Sec.85.1707  Display exemption.

    Where an uncertified vehicle or engine is a display vehicle or 
engine to be used solely for display purposes, will not be operated on 
the public streets or highways except for that operation incident and 
necessary to the display purpose, and will not be sold unless an 
applicable certificate of conformity has been received, no request for 
exemption of the vehicle or engine is necessary.

Sec.85.1709  Export exemptions.

    (a) A new motor vehicle or new motor vehicle engine intended solely 
for export, and so labeled or tagged on the outside of the container and 
on the vehicle or engine itself, shall be subject to the provisions of 
section 203(a) of the Act, unless the importing country has new motor 
vehicle emission standards which differ from the USEPA standards.
    (b) For the purpose of paragraph (a) of this section, a country 
having no standards, whatsoever, is deemed to be a country having 
emission standards which differ from USEPA standards.
    (c) EPA shall periodically publish in the Federal Register a list of 
foreign countries which have in force emissions standards identical to 
USEPA standards and have so notified EPA. New motor vehicles or new 
motor vehicle engines exported to such countries shall comply with USEPA 
certification regulations.
    (d) It is a condition of any exemption for the purpose of export 
under section 203(b)(3) of the Act, that such exemption shall be void ab 
initio with respect to a new motor vehicle or new motor vehicle engine 
intended solely for export where:
    (1) Such motor vehicle or motor vehicle engine is sold, or offered 
for sale, to an ultimate purchaser in the United States for purposes 
other than export; and
    (2) The motor vehicle or motor vehicle engine manufacturer had 
reason to believe that any such vehicle would be

Sec.85.1710  Granting of exemptions.

    (a) If upon completion of the review of an exemption request, as 
required by Sec. Sec.85.1705 and 85.1708, the granting of an exemption 
is deemed appropriate, a memorandum of exemption will be prepared and 
submitted to the person requesting the exemption. The memorandum will 
set forth the basis for the exemption, its scope, and such terms and 
conditions as are deemed necessary. Such terms and conditions will 
generally, include, but are not limited to, agreements by the applicant 
to conduct the exempt activity in the manner described to EPA, create 
and maintain adequate records accessible to EPA at reasonable times, 
employ labels for the exempt engines or vehicles setting forth the 
nature of the exemption, take appropriate measures to assure that the 
terms of the exemption are met, and advise EPA of the termination of the 
activity and the ultimate disposition of the vehicles or engines.
    (b) Any exemption granted pursuant to paragraph (a) of this section 
shall be deemed to cover any subject vehicle or engine only to the 
extent that the specified terms and conditions are complied with. A 
breach of any term or condition shall cause the exemption to be void ab 
initio with respect to any vehicle or engine. Consequently, the causing 
or the performing of an act prohibited under sections 203(a) (1) or (3) 
of the Clean Air Act other than in strict conformity with all terms and 
conditions of this exemption shall render the person to whom the 
exemption is granted, and any other person to whom the provisions of 
section 203 are applicable, liable to suit under sections 204 and 205 of 
the Act.

Sec.85.1716  Approval of an emergency vehicle field modification (EVFM).

    This section describes how you may implement design changes for an 
emergency vehicle that has already been placed into service to ensure 
that the vehicle will perform properly in emergency situations. This 
applies for any light-duty vehicle, light-duty truck, or heavy-duty 
vehicle meeting the definition of emergency vehicle in 40 CFR 86.004-2 
or 86.1803. In this section, ``you'' refers to the certifying 
manufacturer and ``we'' refers to the EPA Administrator and any 
authorized representatives.
    (a) You must notify us in writing of your intent to install or 
distribute an emergency vehicle field modification (EVFM). In some cases 
you may install or distribute an EVFM only with our advance approval, as 
specified in this section.
    (b) Include in your notification a full description of the EVFM and 
any documentation to support your determination that the EVFM is 
necessary to prevent the vehicle from losing speed, torque, or power due 
to abnormal conditions of its emission control system, or to prevent 
such abnormal conditions from occurring during operation related to 
emergency response. Examples of such abnormal conditions may include 
excessive exhaust backpressure from an overloaded particulate trap, or 
running out of diesel exhaust fluid for engines that rely on urea-based 
selective catalytic reduction. Your determination must be based on an 
engineering evaluation or testing or both.
    (c) You may need our advance approval for your EVFM, as follows:
    (1) Where the proposed EVFM is identical to an AECD we approved 
under this part for an engine family currently in production, no 
approval of the proposed EVFM is necessary.
    (2) Where the proposed EVFM is for an engine family currently in 
production but the applicable demonstration is based on an AECD we 
approved under this part for an engine family no longer in production, 
you must describe to us how your proposed EVFM differs from the approved 
AECD. Unless we say otherwise, your proposed EVFM is deemed approved 30 
days after you notify us.
    (3) If we have not approved an EVFM comparable to the one you are 
proposing, you must get our approval before installing or distributing 
it. In this case, we may request additional information to support your 
determination under paragraph (b) of this section, as follows:
    (i) If we request additional information and you do not provide it 
within 30 days after we ask, we may deem that you have retracted your 
request for our approval; however, we may extend this deadline for 
submitting the additional information.
    (ii) We will deny your request if we determine that the EVFM is not 
necessary to prevent the vehicle from losing speed, torque, or power due 
abnormal conditions of the emission control system, or to prevent such 
abnormal conditions from occurring, during operation related to 
emergency response.
    (iii) Unless we say otherwise, your proposed EVFM is deemed approved 
30 days after we acknowledge that you have provided us with all the 
additional information we have specified.
    (4) If your proposed EVFM is deemed to be approved under paragraph 
(c)(2) or (3) of this section and we find later that your EVFM in fact 
does not meet the requirements of this section, we may require you to no 
longer install or distribute it.

engine owners to obtain correction of the nonconformity. This shall 
include designation of the date on or after which the owner can have the 
nonconformity remedied, the time reasonably necessary to perform the 
labor required to correct the nonconformity, and the designation of 
facilities at which the nonconformity can be remedied: Provided, That 
repair shall be completed within a reasonable time designated by the 
Administrator from the date the owner first tenders his vehicle or 
engine after the date designated by the manufacturer as the date on or 
after which the owner can have the nonconformity remedied.
    (6) If some or all of the nonconforming vehicles or engines are to 
be remedied by persons other than dealers or authorized warranty agents 
of the manufacturer, a description of the class of persons other than 
dealers and authorized warranty agents of the manufacturer who will

Protection Agency has determined that your vehicle or engine may be 
emitting pollutants in excess of the Federal emission standards or 
family particulate emission limits, as defined in part 86. These 
standards or family particulate emission limits, as defined in part 86 
were established to protect the public health or welfare from the 
dangers of air pollution.''
    (2) A statement that the nonconformity of any such vehicles or 
engines which have been, if required by the remedial plan, properly 
maintained and used, will be remedied at the expense of the 
manufacturer.
    (3) A description of the proper maintenance or use, if any, upon 
which the manufacturer conditions eligibility for repair under the 
remedial plan and a description of the proof to be required of a vehicle 
or engine owner to demonstrate compliance with such condition. 
Eligibility may not be denied solely on the basis that the vehicle or 
engine owner used parts not manufactured by the original equipment 
vehicle manufacturer, or had repairs performed by outlets other than the 
vehicle manufacturer's franchised dealers.
    (4) A clear description of the components which will be affected by 
the remedy and a general statement of the measures to be taken to 
correct the nonconformity.
    (5) A statement that such nonconformity if not repaired may cause 
the vehicle or engine to fail an emission inspection test when such 
tests are required under State or local law.
    (6) A description of the adverse affects, if any, that an 
uncorrected nonconformity would have on the performance or driveability 
of the vehicle or engine.
    (7) A description of the adverse affects, if any, that such 
nonconformity would have on the functions of other engine components.

[[Page 381]]

    (8) A description of the procedure which the vehicle or engine owner 
should follow to obtain correction of the nonconformity. This shall 
include designation of the date on or after which the owner can have the

vehicle or engine to be recalled has been sold. Such card should be 
addressed to the manufacturer and shall provide a space in which the 
owner may indicate the name and address of the person to whom the 
vehicle or engine was sold.
    (10) The statement: ``In order to ensure your full protection under 
the emission warranty made applicable to your (vehicle or engine) by 
Federal law, and your right to participate in future recalls, it is 
recommended that you have (vehicle or engine) serviced as soon as 
possible. Failure to do so could legally be determined to be a lack of 
proper maintenance of your (vehicle or engine).''
    (b) No notice sent pursuant to paragraph (a) of this section nor any 
other contemporaneous communication sent to vehicle or engine owners or 
dealers shall contain any statement or implication that the

air quality.
    (c) The manufacturer shall be informed of any other requirements 
pertaining to the notification under this section which the 
Administrator has determined are reasonable and necessary to ensure the 
effectiveness of the recall campaign.

delegates authority to the Environmental Appeals Board to issue final 
decisions in appeals filed under this subpart. Appeals directed to the 
Administrator, rather than to the Environmental Appeals Board, will not 
be considered. This delegation of authority to the Environmental Appeals 
Board does not preclude the Environmental Appeals Board from referring 
an appeal or a motion filed under this subpart to the Administrator for 
decision when the Environmental Appeals Board, in its discretion, deems 
it appropriate to do so. When an appeal or motion is referred to the 
Administrator, all parties shall be so notified and the rules in this 
part referring to the Environmental Appeals Board shall be interpreted 
as referring to the Administrator.
    (b) Request for public hearing. (1)(i) If the manufacturer disagrees 
with the Administrator's finding of nonconformity he may request a 
public hearing as described in this section. Requests for such a hearing 
shall be filed with the Administrator not later than 45 days after the 
receipt of the Administrator's notification of nonconformity unless 
otherwise specified by the Administrator. Two copies of such request 
shall simultaneously be served upon the Director of the Manufacturers 
Operations Division and two copies filed with the Hearing Clerk. Failure 
of the manufacturer to request a hearing within the time provided shall 
constitute a waiver of his right to such a hearing. In such a case, the 
manufacturer shall carry out the recall order as required by Sec.
85.1803-6.
    (ii) Subsequent to the expiration of the period for requesting a 
hearing as of right, the Administrator may, in his discretion and for 
good cause shown, grant the manufacturer a hearing to contest the 
nonconformity.
    (2) The request for a public hearing shall contain:
    (i) A statement as to which classes or categories of vehicles or 
engines are to be the subject of the hearing;

    (iii) A statement as to reasons the manufacturer believes he will 
prevail on the merits on each of the issues so raised.
    (3) A copy of all requests for public hearings shall be kept on file 
in the Office of the Hearing Clerk and shall be made available to the 
public during Agency business hours.

other parties copies thereof. A certificate of service shall be provided 
on or accompany each document or paper filed with the Hearing Clerk. 
Documents to be served upon the Director of the Manufacturers Operations 
Division shall be mailed to: Director, Manufacturers Operations 
Division, U.S. Environmental Protection Agency (EG-340), 1200 
Pennsylvania Ave., NW., WSM, Washington, DC 20460. Service by mail is 
complete upon mailing.
    (d) Time. (1) In computing any period of time prescribed or allowed 
by this section, except as otherwise provided, the day of the act or 
event from which the designated period of time begins to run shall not 
be included. Saturdays, Sundays, and Federal legal holidays shall be 
included in computing any such period allowed for the filing of any 
document or paper, except that when such period expires on a Saturday, 
Sunday, or Federal legal holiday, such period shall be extended to 
include the next following business day.
    (2) A prescribed period of time within which a party is required or 
permitted to do an act shall be computed from the time of service,

added to the prescribed period.
    (e) Consolidation. The Administrator or the Presiding Officer in his 
discretion may consolidate two or more proceedings to be held under this 
section for the purpose of resolving one or more issues whenever it 
appears that such consolidation will expedite or simplify consideration 
of such issues. Consolidation shall not affect the right of any party to 
raise issues that could have been raised if consolidation had not 
occurred.
    (f) Notice of public hearings. (1) Notice of a public hearing under 
this section shall be given by publication in the Federal Register.

to intervene.
    (2) In passing upon a petition to intervene, the following factors, 
among other things, shall be considered by the Presiding Officer:

[[Page 384]]

    (i) The nature of the petitioner's interest including the nature and 
the extent of the property, financial, environmental protection, or 
other interest of the petitioner;
    (ii) The effect of the order which may be entered in the proceeding 
on petitioner's interest;

    (4) All petitions to be made an intervener shall be reviewed by the 
Presiding Officer using the criteria set forth in paragraph (g)(2) of 
this section and considering any oppositions to such petition. Where the 
petition demonstrates that the petitioner's interest is limited to 
particular issues, the Presiding Officer may, in granting such petition, 
limit petitioner's participation to those particular issues only.
    (5) If the Presiding Officer grants the petition with respect to any 
or all issues, he shall so notify, or direct the Hearing Clerk to 
notify, the petitioner and all parties. If the Presiding Officer denies 
the petition he shall so notify, or direct the Hearing Clerk to notify, 
the petitioner and all parties and shall briefly state the reasons why 
the petition was denied.
    (6) All petitions to be made an intervener shall include an 
agreement by the petitioner, and any person represented by the 
petitioner, to be subject to examination and cross-examination and to 
make any supporting and relevant records available at its own expense 
upon the request of the Presiding Officer, on his own motion or the 
motion of any party or other intervener. If the intervener fails to 
comply with any such request, the Presiding Officer may in his 
discretion, terminate his status as an intervener.
    (h) Intervention by motion. Following the expiration of the time 
prescribed in paragraph (g) of this section for the submission of 
petitions to intervene in a hearing, any person may file a motion with 
the Presiding Officer to intervene in a hearing. Such a motion must 
contain the information and commitments required by paragraphs (g) (2) 
and (6) of this section, and, in addition, must show that there is good 
cause for granting the motion and must contain a statement that the 
intervener shall be bound by agreements, arrangements, and other

[[Page 385]]

tests and inspections may be submitted in written form.
    (7) To enforce agreements and orders requiring access as authorized 
by law;
    (8) To require the filing of briefs on any matter on which he is 
required to rule;
    (9) To require any party or any witness, during the course of the 
hearing, to state his position on any issue;
    (10) To take or cause depositions to be taken whenever the ends of 
justice would be served thereby;
    (11) To make decisions or recommend decisions to resolve the 
disputed issues of the record of the hearing.

Presiding Officer prior to the hearing, each party shall make available 
to the other parties the names of the expert and other witnesses the 
party expects to call, together with a brief summary of their expected 
testimony and a list of all documents and exhibits which the party 
expects to introduce into evidence. Thereafter, witnesses, documents, or 
exhibits may be added and summaries of expected testimony amended upon 
motion by a party.
    (2) The Presiding Officer, may, upon motion by a party or other 
person, and for good cause shown, by order (i) restrict or defer 
disclosure by a party of the name of a witness or a narrative summary of

appropriate measures to protect a witness. Any party affected by any 
such action shall have an adequate opportunity, once he learns the name 
of a witness and obtains the narrative summary of his expected 
testimony, to prepare for the presentation of his case.
    (m) Other discovery. (1) Except as so provided by paragraph (l) of 
this section, further discovery, under this paragraph, shall be 
permitted only upon determination by the Presiding Officer:
    (i) That such discovery will not in any way unreasonably delay the 
proceeding;
    (ii) That the information to be obtained is not obtainable 
voluntarily; and
    (iii) That such information has significant probative value. The 
Presiding Officer shall be guided by the procedures set forth in the 
Federal Rules of Civil Procedure, where practicable, and the precedents 
thereunder, except that no discovery shall be undertaken except upon 
order of the Presiding Officer or upon agreement of the parties.
    (2) The Presiding Officer shall order depositions upon oral 
questions only upon a showing of good cause and upon a finding that:
    (i) The information sought cannot be obtained by alternative 
methods; or

[[Page 386]]

    (ii) There is a substantial reason to believe that relevant and 
probative evidence may otherwise not be preserved for presentation by a 
witness at the hearing.
    (3) Any party to the proceeding desiring an order of discovery shall 
make a motion or motions therefor. Such a motion shall set forth:
    (i) The circumstances warranting the taking of the discovery;
    (ii) The nature of the information expected to be discovered; and
    (iii) The proposed time and place where it will be taken. If the 
Presiding Officer determines the motion should be granted, he shall 
issue an order for the taking of such discovery together with the 
conditions and terms thereof.
    (4) Failure to comply with an order issued pursuant to this 
paragraph may lead to the inference that the information to be 
discovered would be adverse to the person or party from whom the 
information was sought.
    (n) Protective orders: in camera proceedings. (1) Upon motion by a 
party or by the person from whom discovery is sought, and upon a showing 
by the movant that the disclosure of the information to be discovered, 
or a particular part thereof, (other than emission data) would result in 
methods or processes entitled to protection as trade secrets of such 
person being divulged, the Presiding Officer may enter a protective 
order with respect to such material. Any protective order shall contain 
such terms governing the treatment of the information as may be 
appropriate under the circumstances to prevent disclosure outside the 
hearing: Provided, That the order shall state that the material shall be 
filed separately from other evidence and exhibits in the hearing. 
Disclosure shall be limited to parties to the hearing, their counsel and 
relevant technical consultants, and authorized representatives of the 
United States concerned with carrying out the Act. Except in the case of 
the government, disclosure may be limited to counsel to parties who 
shall not disclose such information to the parties themselves. Except in 
the case of the government, disclosure to a party or his counsel shall 
be conditioned on execution of a sworn statement that no disclosure of 
the information will be made to persons not entitled to receive it under 
the terms of the protective order. (No such provision is necessary where 
government employees are concerned because disclosure by them is subject 
to the terms of 18 U.S.C. 1905.)
    (2)(i) A party or person seeking a protective order may be permitted 
to make all or part of the required showing in camera. A record shall be 
made of such in camera proceedings. If the Presiding Officer enters a 
protective order following a showing in camera, the record of such 
showing shall be sealed and preserved and made available to the Agency 
or court in the event of appeal.
    (ii) Attendance at any in camera proceeding may be limited to the 
Presiding Officer, the Agency, and the person or party seeking the 
protective order.
    (3) Any party, subject to the terms and conditions of any protective 
order issued pursuant to paragraph (n)(1) of this section, desiring for 
the presentation of his case to make use of any in camera documents or 
testimony shall make application to the Presiding Officer by motion 
setting forth the justification therefor. The Presiding Officer, in 
granting any such motion, shall enter an order protecting the rights of 
the affected persons and parties and preventing unnecessary disclosure 
of such information, including the presentation of such information and 
oral testimony and cross-examination concerning it in executive session, 
as in his discretion is necessary and practicable.
    (4) In the submittal of proposed findings, briefs, or other papers, 
counsel for all parties shall make a good faith attempt to refrain from 
disclosing the specific details of in camera documents and testimony. 
This shall not preclude references in such proposed findings, briefs, or 
other papers to such documents or testimony including generalized 
statements based on their contents. To the extent that counsel consider 
it necessary to include specific details in their presentations, such 
data shall be incorporated in separate proposed findings, briefs, or 
other papers marked ``confidential'', which

proposed findings and conclusions except when his order disposing of the 
proceeding otherwise informs the parties of the action taken by him 
thereon.
    (t) Decision of the Presiding Officer. (1) Unless extended by the

(1) If, after the expiration of the period for taking an appeal as 
provided for by paragraph (u) of this section, no notice of intention to 
appeal the decision of the Presiding Officer has been filed, or if 
filed, not perfected, the Hearing Clerk shall so notify the 
Environmental Appeals Board.
    (2) The Environmental Appeals Board, upon receipt of notice from the 
Hearing Clerk that no notice of intention to appeal has been filed, or 
if filed, not perfected pursuant to paragraph (u) of this section, may, 
on its own motion, within the time limits specified in paragraph (t)(2) 
of this section, review the decision of the Presiding Officer. Notice of 
the intention of the Environmental Appeals Board to review the decision 
of the Presiding Officer shall be given to all parties and shall set 
forth the scope of such review and the issue which shall be considered 
and shall make provision for filing of briefs.
    (w) Decision on appeal or review. (1) Upon appeal from or review of 
the Presiding Officer's decision, the Environmental Appeals Board shall 
consider such parts of the record as are cited or as may be necessary to 
resolve the issues presented and, in addition shall to the extent 
necessary or desirable exercise all the powers which it could have 
exercised if it had presided at the hearing.
    (2) In rendering its decision, the Environmental Appeals Board shall 
adopt, modify, or set aside the findings, conclusions, and rule or order 
contained in the decision of the Presiding Officer and shall set forth 
in its decision a statement of the reasons or bases for its action.
    (3) In those cases where the Environmental Appeals Board determines 
that it should have further information or additional views of the 
parties as to the form and content of the rule or order to be issued, 
the Environmental Appeals Board, in its discretion, may withhold final 
action pending the receipt of such additional information or views, or 
may remand the case to the Presiding Officer.
    (x) Reconsideration. Within twenty (20) days after issuance of the 
Environmental Appeals Board's decision, any party may file with the 
Environmental Appeals Board a petition for reconsideration of such 
decision, setting forth the relief desired and the grounds in support 
thereof. Any petition filed under this subsection must be confined to 
new questions raised by the decision or the final order and upon which 
the petitioner had no opportunity to argue before the Presiding Officer 
or the Environmental Appeals Board. Any party desiring to oppose such a 
petition shall file and answer thereto within ten (10) days after the 
filing of the petition. The filing of a petition for reconsideration 
shall not operate to stay the effective date of the decision or order or 
to toll the running of any statutory time period affecting such decision 
or order unless specifically so ordered by the Environmental Appeals 
Board.
    (y) Accelerated decision: Dismissal. (1) The Presiding Officer, upon 
motion of any party or sua sponte, may at any time render an accelerated

party with prejudice, under any of the following conditions:
    (i) Failure to state a claim upon which relief can be granted, or 
direct or collateral estoppel;
    (ii) There is no genuine issue of material fact and a party is 
entitled to judgment as a matter of law; or
    (iii) Such other and further reasons as are just, including 
specifically failure to obey a procedural order of the Presiding 
Officer.
    (2) If under this paragraph an accelerated decision is issued as to 
all the issues and claims joined in the proceeding, the decision shall 
be treated for the purposes of these procedures as the decision of the 
Presiding Officer as provided in paragraph (p) of this section.
    (3) If under this paragraph, judgment is rendered on less than all 
issues or claims in the proceeding, the Presiding Officer shall 
determine what material facts exist without substantial controversy and 
what material facts are actually and in good faith controverted. He 
shall thereupon issue an

[[Page 390]]

order specifying the facts which appear without substantial controversy, 
and the issues and claims upon which the hearing will proceed.
    (z) Conclusion of hearing. (1) If, after the expiration of the 
period for taking an appeal as provided for by paragraph (u) of this 
section, no appeal has been taken from the Presiding Officer's decision, 
and, after the expiration of the period for review by the Environmental 
Appeals Board on its own motion as provided for by paragraph (v) of this 
section, the Environmental Appeals Board does not move to review such 
decision, the hearing will be deemed to have ended at the expiration of 
all periods allowed for such appeal and review.
    (2) If an appeal of the Presiding Officer's decision is taken 
pursuant to paragraph (u) of this section, or if, in the absence of such 
appeal, the Environmental Appeals Board moves to review the decision of 
the Presiding Officer pursuant to paragraph (v) of this section, the 
hearing will be deemed to have ended upon the rendering of a final 
decision by the Environmental Appeals Board.
    (aa) Judicial Review. (1) The Administrator hereby designates the 
Deputy General Counsel, Environmental Protection Agency as the officer 
upon whom copy of any petition for judicial review shall be served.
    Such officer shall be responsible for filing in the court the record 
on which the order of the Environmental Appeals Board is based.
    (2) Before forwarding the record to the court, the Agency shall 
advise the petitioner of costs of preparing it and as soon as payment to 
cover fees is made shall forward the record to the court.

pursuant to this subpart is entitled to confidential treatment, the 
information covered by that confidentiality claim will be disclosed by 
the Environmental Appeals Board only to the extent and by means of the 
procedures set forth in part 2, subpart B, of this chapter.
    (e) Information provided without a claim of confidentiality at the 
time of submission may be made available to the public by EPA without

 Sec. Appendix A to Subpart S of Part 85--Interpretive Ruling for Sec.
                         85.1803--Remedial Plans

    The purpose of this rule is to set forth EPA's interpretation 
regarding one aspect of a motor vehicle or motor vehicle engine 
manufacturer's recall liability under section 207(c)(1) of the Clean Air 
Act, 42 U.S.C. 7641(c)(1). This rule will provide guidance to vehicle 
and engine manufacturers to better enable them to submit acceptable 
remedial plans.
    Section 207(c)(1) requires the Administrator to base a recall order 
on a determination that a substantial number of in-use vehicles or 
engines within a given class or category of vehicles or engines, 
although properly maintained and used, fail to conform to the 
regulations prescribed under section 202

[[Page 391]]

when in actual use throughout their useful lives. After making such a 
determination, he shall require the manufacturer to submit a plan to 
remedy the nonconformity of any such vehicles or engines. The plan shall 
provide that the manufacturer will remedy, at the manufacturer's 
expense, all properly maintained and used vehicles which experienced the 
nonconformity during their useful lives regardless of their age or 
mileage at the time of repair.

for evidence pursuant to paragraph (c) of this section; or
    (2) Notwithstanding the evidence presented pursuant to paragraph (c) 
of this section, the manufacturer is able to prove that the vehicle 
failed an emission short test because:
    (i) The vehicle was abused, or
    (ii) An instruction for the proper maintenance and use was performed 
in a manner resulting in a component's being improperly installed or a 
component or related parameter's being adjusted substantially outside of

Sec.85.2105  Aftermarket parts.

    (a) No valid emission performance warranty claim shall be denied on 
the basis of the use of a properly installed certified aftermarket part 
in the maintenance or repair of a vehicle. A vehicle manufacturer that 
honors a valid emission performance warranty claim involving a certified 
aftermarket part may seek reimbursement for reasonable expenses incurred 
in honoring the claim by following the warranty claim procedures listed 
in Sec.85.2107(c).
    (b) Except as provided in Sec.85.2104(h), a vehicle manufacturer 
may deny an emission performance warranty claim on the basis of an 
uncertified aftermarket part used in the maintenance or repair of a 
vehicle if the vehicle manufacturer can demonstrate that the vehicle's 
failure to meet emission standards was caused by use of the uncertified 
part. A warranty claim may be denied if the vehicle manufacturer submits 
a written document to the vehicle owner that the vehicle owner is unable 
or unwilling to refute. The document must:
    (1) Establish a causal connection between the emissions short test 
failure and use of the uncertified part, and,
    (2) Assert that:

[[Page 398]]

    (i) Removal of the uncertified part and installation of any 
comparable certified or original equipment part previously removed or 
replaced during installation of the uncertified part will resolve the 
observed emissions failure in the vehicle, and/or
    (ii) Use of the uncertified part has caused subsequent damage to 
other specified certified components such that replacement of these 
components would also be necessary to resolve the observed vehicle 
emissions failure, and,
    (3) List all objective evidence as defined in Sec.85.2102 that was 
used in the determination to deny warranty. This evidence must be made 
available to the vehicle owner or EPA upon request, and
    (c) A part not required to be replaced at a definite interval in 
accordance with the written instructions for maintenance and use shall 
be warranted for the full term of any warranty mandated by the Act. 
Instructions to replace a component only if checked and found to be 
operating below specification shall have no bearing on warranty 
coverage, unless an owner did not follow such an instruction prior to 
the short test failure and noncompliance with that instruction caused 
the failure of another vehicle component relevant to the nonconformity.

[45 FR 34839, May 22, 1980, as amended at 54 FR 32587, Aug. 8, 1989]



Sec.85.2106  Warranty claim procedures.

    (a) A claim under the emission performance warranty may be raised 
immediately upon the failure of an EPA-approved emission test if, as a 
result of that failure, an owner is required to take action of any kind 
in order to avoid imposition of a penalty or sanction. An owner need not 
suffer the loss of the right to use a vehicle, be fined, incur repair 
expenses, or actually bear any penalty or sanction to satisfy the 
requirement of Sec.85.2103(a)(3). That requirement shall be met if a 
test failure sets a procedure in motion under which the owner will bear 
a penalty or sanction if a vehicle is not brought into conformity or 
repaired to some specified extent within some specified period of time.
    (b) A warranty claim may be submitted by bringing a vehicle to:
    (1) Any repair facility authorized by the vehicle manufacturer to 
service that model vehicle, or
    (2) Any repair facility authorized by the vehicle manufacturer to 
perform emission performance warranty repairs for that model vehicle.
    (c) To the extent required by any Federal or State law, whether 
statutory or common law, a vehicle manufacturer shall be required to 
provide a means for non-franchised repair facilities to perform emission 
performance warranty repairs.
    (d) The manufacturer of each vehicle to which the warranty is 
applicable shall establish procedures as to the manner in which a claim 
under the emission performance warranty is to be processed. The 
procedures shall:
    (1) Provide for a final decision by the vehicle manufacturer within 
a reasonable time, not to exceed 30 days from the time at which the 
vehicle is initially presented for repair or within the time period 
during which an owner is required by local, State or federal law to have 
the vehicle repaired without incurring further penalties or sanctions 
(whichever is shorter), unless a delay
    (i) Is requested by the vehicle owner, or
    (ii) Is caused by an event not attributable to the vehicle 
manufacturer or the warranty repair facility; and
    (2) Require that if the facility at which the vehicle is initially 
presented for repair is unable for any reason to honor the particular 
claim, then, unless this requirement is waived in writing by the vehicle 
owner, the repair facility shall forward the claim to an individual or 
office authorized to make emission performance warranty determinations 
for the manufacturer.
    (e) Within the time period specified in paragraph (d) of this 
section the manufacturer shall:
    (1) Notify the owner that it will honor the claim; or
    (2) Provide the owner, in writing, with an explanation of the basis 
upon which the claim is being denied; or
    (3) If the basis of the claim denial involves use of an uncertified 
part, provide the owner in writing with an explanation of the basis upon 
which the

[[Page 399]]

claim is being denied according to all criteria specified in Sec.
85.2105(b).
    (f) Failure to notify an owner within the required time period (as 
determined under paragraph (d) of this section) for reasons that are not 
attributable to the vehicle owner or events which are not beyond the 
control of the vehicle manufacturer or the repair facility, shall result 
in the vehicle manufacturer being responsible for repairing the 
warranted items free of charge to the vehicle owner.
    (g) The vehicle manufacturer shall incur all costs associated with a 
determination that an emission performance warranty claim is valid.

[45 FR 34839, May 22, 1980, as amended at 54 FR 32588, Aug. 8, 1989]



Sec.85.2107  Warranty remedy.

    (a) The manufacturer's obligation under the emission performance 
warranty shall be to make all adjustments, repairs or replacements 
necessary to assure that the vehicle complies with applicable emission 
standards of the U.S. Environmental Protection Agency, that it will 
continue to comply for the remainder of its useful life (if proper 
maintenance and operation are continued), and that it will operate in a 
safe manner. The manufacturer shall bear all costs incurred as a result 
of the above obligation, except that after the first 24 months or 24,000 
miles (whichever first occurs) the manufacturer shall be responsible 
only for:
    (1) The adjustment, repair or replacement of those components which 
have been installed in or on a vehicle for the sole or primary purpose 
of reducing vehicle emissions, and which were not in general use prior 
to model year 1968; and
    (2) All other components which must be adjusted, repaired or 
replaced to enable a component repaired or replaced under paragraph 
(a)(1) of this section to perform properly.
    (b) Under the Emissions Performance Warranty, the manufacturer shall 
be liable for the total cost of the remedy for any vehicle validly 
presented for repair to any authorized service facility authorized by 
the vehicle manufacturer. State or local limitations as to the extent of 
the penalty or sanction imposed upon an owner of a failed vehicle shall 
have no bearing on this liability.
    (c) The remedy provided under paragraph (a) of this section shall 
include the repair or replacement of certified parts as required in 
Sec.85.2105(a). To seek reimbursement from the involved certified 
aftermarket part manufacturer for reasonable expenses incurred due to 
the certified aftermarket parts determined to be the cause of a 
performance warranty failure, the vehicle manufacturer must:
    (1) Retain all parts replaced during the performance warranty 
repair, and
    (2) Follow the procedures laid out in Sec.85.2117.
    (d) If a manufacturer is unable (for reasons not attributable to the 
vehicle owner or events beyond the control of the vehicle manufacturer 
or an authorized repair facility) to repair a vehicle within the time 
period specified under Sec.85.2106(d) after the initial presentation 
of the vehicle to an authorized repair facility, then the owner shall be 
entitled to have the warranty remedy performed, at the expense of the 
manufacturer, by any repair facility of the owner's choosing.
    (e) The vehicle manufacturer may deny warranty for a failure caused 
by an uncertified part in accordance with the criteria in Sec.85.2105.

Sec.85.2114  Basis of certification.

    (a) Prior to certifying, the aftermarket part manufacturer must 
determine:
    (1) Whether the part to be certified is an emission related part as 
defined in Sec.85.2102. The MOD Director shall deny certification to 
any parts which he or she determines is not an emission related part.
    (2) The vehicle or engine configurations for which this part is 
being certified. These are the vehicle and engine designs for which the 
aftermarket part manufacturer intends to sell the certified aftermarket 
part.
    (3) Whether the part qualifies under one of the part categories, 
listed in Sec.85.2122 of this subpart that are eligible to certify 
using emission critical parameters and, if so, whether the manufacturer 
elects to demonstrate certification using emission critical parameters. 
An aftermarket part may be certified under this category only if the 
part's emission-critical parameters, as set forth in Sec.85.2122, are 
equivalent to those of the original equipment or previously certified 
part it is to replace. Compliance with the emission-critical parameters 
discussed in paragraph (b) of this section may be demonstrated by 
compliance with the relevant test procedures and criteria specified in 
appendix I to this subpart. The requirements of this paragraph apply to 
all on-road vehicles and engines. Alternatively, the manufacturer may 
elect to demonstrate certification compliance according to the emission 
test procedures described in paragraph (c) of this section.
    (b) For parts eligible to certify using emission-critical 
parameters, certification compliance can be demonstrated as follows. (1) 
The durability procedure contained in appendix I to this subpart can be 
used. As an alternative, the aftermarket part manufacturer may use a 
different durability procedure if it can demonstrate to the MOD Director 
that the alternative procedure results in an improved technical 
evaluation of the part's influence on vehicle or engine emissions for 
its useful life mileage interval, or results in a significant cost 
savings to the aftermarket part manufacturer with no loss in technical 
validity compared to the recommended durability procedure. The 
aftermarket part manufacturer shall receive the written approval from 
the MOD Director prior to implementation of the alternative procedures.
    (2) Compliance with certification requirements is based on 
conformance with all emission-critical parameters in Sec.85.2122. This 
shall be accomplished by performing such procedures, tests, or analyses 
described in appendix I, or other procedures subject to the MOD 
Director's approval, necessary to ascertain with a high degree of 
certainty the emission-critical parameter specifications and tolerances 
for the aftermarket part and the original equipment or previously 
certified part for which an equivalent aftermarket certified part is to 
be used.
    (i) If information is available in appendix I of this subpart to 
identify the applicable emission-critical parameters, the aftermarket 
part certifier must use such information.
    (ii) If sampling and analysis of original equipment or previously 
certified parts is relied upon, the aftermarket part certifier must use 
sound statistical sampling techniques to ascertain the mean and range of 
the applicable emission parameters.
    (iii) If an aftermarket part replaces more than one part on the same 
application, it may be certified only if the aftermarket part meets the 
applicable emission-critical parameters of Sec.85.2122 for each part 
or parts which the aftermarket part is to replace. If an aftermarket 
part is to replace more than one part or an entire system, compliance 
must be demonstrated for

[[Page 403]]

all emission-critical parameters involved, except those which relate 
solely to the interface between the parts being replaced by the 
aftermarket part.
    (c) For parts certifying on the basis of emission test results, 
durability demonstration testing shall be conducted as follows. (1) 
Prior to certification emission testing, the actual aftermarket part 
used for certification testing must meet the durability demonstration 
requirements of this paragraph for at least the part's useful life 
mileage interval.
    (i) If an original equipment part has no scheduled replacement 
interval, then the useful life mileage interval of the aftermarket part 
of that type or which replaces the function of that part may be 
certified with a service interval less than the useful life of the motor 
vehicle or motor vehicle engine, or
    (ii) If any provision of 40 CFR part 86 establishes a minimum 
replacement or service interval for an original equipment part during 
vehicle or engine certification, then the useful life mileage interval 
of the aftermarket part of that type or which replaces the function of 
that part is said minimum interval.
    (2) The part manufacturer must decide whether it can demonstrate to 
the MOD Director that, during normal vehicle operation, the candidate 
part will not accelerate deterioration of any original equipment 
emission related parts. This demonstration must be based on technical 
rationale that shows that the candidate part has no significant physical 
or operational effect on any original emission components or system 
which would be different than that experienced by the vehicle operating 
with all original equipment emission system parts. The part's effect on 
each major emission system must be addressed separately in the 
demonstration.
    (i) If the aftermarket part to be certified accelerates 
deterioration of any existing emission related parts then certification 
shall be carried out as specified under the paragraph (c)(3) of this 
section for parts that accelerate deterioration of existing emission 
related parts.
    (ii) If the aftermarket part manufacturer can demonstrate that the 
part to be certified will not accelerate deterioration of any existing 
emission related components, then the manufacturer can certify according 
to paragraph (c)(4) in this section for parts demonstrated to not 
accelerate deterioration of existing emission related parts.
    (3) For aftermarket parts that accelerate deterioration of existing 
emission related parts during normal operation. (i) The aftermarket test 
part can be installed on the durability test vehicle and aged for 50,000 
miles using the vehicle durability driving schedules contained in part 
86, appendix IV. As an alternative, the aftermarket part manufacturer 
may use a different durability procedure if it can demonstrate to the 
MOD Director that the alternative procedure results in an improved 
technical evaluation of the part's influence on vehicle or engine 
emissions for the part's useful life mileage interval, or results in a 
significant cost savings to the aftermarket part manufacturer with no 
loss in technical validity compared to the recommended durability 
schedules in part 86, appendix IV. The aftermarket part manufacturer 
shall receive the written approval from the MOD Director prior to 
implementation of the alternative procedures.

    Note: At the time of certification emission testing, the same part 
and vehicle combination used for mileage accumulation shall be used for 
emission testing.

    (ii) Where the comparable original equipment part has a recommended 
replacement interval of less than 50,000 miles, the test part shall be 
replaced no sooner than its useful life mileage interval during the 
required 50,000 mile durability demonstration.

    Note: At the time of certification emission testing, one of the 
aftermarket parts that accumulated at least its useful life mileage 
during the aging process under this paragraph shall be installed on the 
durability test vehicle that has accumulated 50,000 miles.

    (4) For aftermarket parts demonstrated not to accelerate 
deterioration on existing emission related parts during normal 
operation, the part manufacturer must determine whether the part will 
cause a noticeable change in vehicle driveability.

[[Page 404]]

    (i) Parts that cause no noticeable change in vehicle driveability, 
performance, and/or fuel economy when the part fails, the durability 
driving schedules contained in part 86, appendix IV can be used. As an 
alternative, the aftermarket part manufacturer may use a different 
durability procedure if it can demonstrate to the MOD Director that the 
alternative procedure results in an improved technical evaluation of the 
part's influence on vehicle or engine emissions for its useful life 
mileage interval, or results in a significant cost savings to the 
aftermarket part manufacturer with no loss in technical validity 
compared to the durability schedules in part 86, appendix IV. The 
aftermarket part manufacturer shall receive the written approval from 
the MOD Director prior to implementation of the alternative procedures.
    (ii) Parts demonstrated to cause a noticeable change in vehicle 
driveability, performance, and/or fuel economy when the part fails, are 
exempt from aging if the part manufacturer can demonstrate to the MOD 
Director that the primary failure mode of the aftermarket component or 
system affects the driveability, performance, and/or fuel economy of the 
vehicle at a level readily detectable by the driver and likely to result 
in near term repair of failing components and correction of the 
emissions failure. (Use of on-board diagnostics and malfunction 
indicators as covered in paragraph (g) of this section is not 
necessarily an adequate demonstration that the certified part will be 
replaced. The part manufacturer must demonstrate that the diagnostic and 
malfunction indicator system will routinely result in repair or 
replacement of the part in use).
    (5) For parts which only affect evaporative emissions performance, 
the aftermarket part manufacturer shall determine and demonstrate to the 
MOD Director the appropriate durability procedure to age its part. The 
demonstration shall include all documentation, analyses, and test 
results that support this determination, and the documentation that 
support the durability procedure results shall be submitted with the 
notification of intent to certify as per Sec.85.2115 and is subject to 
MOD Director's review.
    (6) Durability demonstration vehicle selection. The demonstration 
vehicle used must represent the ``worst case'' of all the configurations 
for which the aftermarket part is being certified. The worst case 
configuration shall be that configuration which will likely cause the 
most deterioration in the performance characteristics of the aftermarket 
part which influence emissions during the part's useful life mileage. 
The worst case configuration shall be selected from among those 
configurations for which the aftermarket part is to be certified. One of 
the following two methods shall be used to select the worst case 
durability demonstration vehicle(s):
    (i) In the first method, the selection shall be based on a technical 
judgment by the aftermarket part manufacturer of the impact of the 
particular design, or calibration of a particular parameter or 
combination of parameters, and/or an analysis of appropriate data, or
    (ii) In the second alternative method, the selection shall be made 
from among those vehicle configurations with the heaviest equivalent 
test weight, and within that group, the largest displacement engine.
    (d) For parts certifying on the basis of emission test results, 
certification compliance shall be demonstrated as follows. (1) The 
emission test to be used is the Federal Test Procedure as set forth in 
the applicable portions of 40 CFR part 86. Certification emission 
testing must be carried out using representative production aftermarket 
parts as provided in paragraph (e) of this section. The test results 
must demonstrate that the proper installation of the certified 
aftermarket part will not cause the vehicle to fail to meet any 
applicable Federal emission requirements under section 202 of the Act.
    (2) The following portions of the Federal Test Procedure are not 
required to be performed when certifying a part using emission testing:
    (i) The evaporative emissions portion, if the aftermarket 
manufacturer has an adequate technical basis for believing that the part 
has no effect on the vehicle's evaporative emissions;

[[Page 405]]

    (ii) The exhaust emissions portion, if the part manufacturer has an 
adequate technical basis for believing that the part has no affect on 
the vehicle's exhaust emissions; and
    (iii) Other portions therein which the part manufacturer believes 
are not relevant; Provided, That the part manufacturer has requested and 
been granted a waiver in writing by the MOD Director for excluding such 
portion.
    (3) Exhaust Emission Testing. Certification exhaust emission testing 
for aftermarket parts shall be carried out in the following manner:
    (i) For light duty vehicle parts that accelerate deterioration of 
existing emission related parts, at least one emission test is required. 
The test(s) shall be performed according to the Federal Test Procedure 
on the same test vehicle and aftermarket part combination that was 
previously aged as required. The results of all tests performed shall be 
averaged for each emission constituent. The average values shall meet 
all applicable Federal emission requirements under section 202 of the 
Act.
    (A) For aftermarket parts where the comparable original equipment 
part has no recommended replacement interval, the same part and vehicle 
combination used for the durability demonstration shall be used for 
certification exhaust emission testing.
    (B) For aftermarket parts where the comparable original equipment 
part has a recommended replacement interval of less than 50,000 miles, 
one of the aftermarket parts that accumulated at least the part's useful 
life mileage during the durability demonstration must be installed on 
the durability demonstration vehicle that has accumulated 50,000 miles 
for certification exhaust emission testing.
    (ii) For light duty truck parts that accelerate deterioration of 
existing emission related parts.
    (A) An emission test shall be performed on emission test vehicles at 
4000 miles and at 50,000 miles, with the part installed. Exhaust 
emission deterioration factors for the test vehicle shall be calculated 
from these two test results. The aftermarket part manufacturer may elect 
to perform other emission tests at interim mileages. However, any 
interim tests must be spaced at equal mileage intervals. If more than 
one test is performed at any one mileage point, then all tests at this 
point shall be averaged prior to determining the deterioration factor. 
The deterioration factor shall be calculated using the least squares 
straight line method, in accordance with Sec.86.088-28(a). The 
deterioration factor for each emission constituent shall be used to 
linearly project the 50,000 mile test result out to 120,000 miles. The 
projected 120,000 mile test result shall meet light duty truck emission 
standards.
    (B) As an option, the light-duty truck part manufacturer may 
durability age the test vehicle and aftermarket part to 120,000 miles, 
and then perform one Federal Test Procedure test. The actual test 
results in this case must pass all Federal emission standards.
    (iii) For parts demonstrated to not accelerate deterioration of 
existing emission related parts during normal operation:
    (A) If parts cause no noticeable change in vehicle driveability, 
performance, and/or fuel economy when the part fails, the certification 
exhaust emission test vehicle need not be the same vehicle as that used 
for durability demonstration. Upon completion of aging, one Federal Test 
Procedure test shall be performed with the aged aftermarket part 
installed on a test vehicle that has just completed one Federal Test 
Procedure test in the original equipment configuration (i.e., before the 
aftermarket part or system is installed). If more than one test is 
performed either before or after the aftermarket part is installed, then 
an equivalent number of tests must be performed in both configurations. 
The results of all tests performed before the part is installed shall be 
averaged and the results of all tests performed after the part is 
installed shall be averaged for each emission constituent. The 
difference in Federal Test Procedure emission results between the tests 
with the aged aftermarket part installed and the test vehicle in the 
original equipment configuration shall be less than or equal to the 
certification vehicle emission margin of any and all of the 
certification test vehicles from the

[[Page 406]]

various configurations for which the aftermarket part is being 
certified.
    (B) For parts demonstrated to cause a noticeable change in vehicle 
driveability, performance, and/or fuel economy when the part fails, no 
durability aging of the part is required before certification emission 
testing. One Federal Test Procedure test shall be performed on the test 
vehicle in its original equipment configuration (i.e., before the 
aftermarket part or system is installed) and one test with an 
aftermarket part representative of production (as provided in paragraph 
(e) of this section) installed on the test vehicle. If more than one 
test is performed either before or after the aftermarket part is 
installed, then an equivalent number of tests must be performed in both 
configurations. The results of all tests performed with the aftermarket 
part installed shall be averaged and the results of all tests performed 
in the original equipment configuration shall be averaged for each 
emission constituent. The difference in Federal Test Procedure emission 
results between the tests with the aftermarket part installed and the 
test vehicle in the original equipment configuration shall be less than 
or equal to the certification vehicle emission margin of any and all of 
the certification test vehicles from the various configurations for 
which the aftermarket part is being certified.
    (4) Evaporative emission testing. For parts determined by the part 
manufacturer (with appropriate technical rationale) to affect only 
evaporative emissions performance, at least one evaporative emissions 
portion of the Federal Test Procedure test shall be performed on the 
vehicle in its original equipment configuration and at least one with 
the aftermarket part installed. Both the original equipment and 
aftermarket part shall be aged according to paragraph (c)(5) of this 
section prior to testing. If more than one test is performed either 
before or after the aftermarket part is installed, then an equivalent 
number of tests must be performed in both configurations. The emission 
results of all tests performed before the part is installed shall be 
averaged and the emission results of all tests performed after the part 
is installed shall be averaged. The difference in Federal Test Procedure 
emission results between the tests with the aged aftermarket part 
installed and the test vehicle in the original equipment configuration 
shall be less than or equal to the certification vehicle emission margin 
of any and all of the certification test vehicles from the various 
configurations for which the aftermarket part is being certified.
    (5) Emission test vehicle selection: The test vehicle used must 
represent the ``worst case'' with respect to emissions of all those 
configurations for which the aftermarket part is being certified. The 
worst case configuration shall be that configuration which, having the 
aftermarket part installed, is least likely to meet the applicable 
emission standards among all those configurations on which the 
aftermarket part is intended to be installed as a certified aftermarket 
part. One of the following two methods shall be used to select the worst 
case emission test vehicle(s):
    (i) In the first method, the selection shall be based on a technical 
judgment by the aftermarket part manufacturer of the impact of the 
particular design or calibration of a particular parameter or 
combination of parameters and/or an analysis of appropriate data, or
    (ii) In the second alternative method, two defined worst case test 
vehicles shall be selected from the vehicle configurations using the 
following criteria:
    (A) The first test vehicle is that engine family for which the 
largest number of parts are projected to be sold. Within that family the 
manufacturer shall select the configurations with the heaviest 
equivalent test weight, and then within that group the configuration 
with the largest displacement engine.
    (B) The second test vehicle shall be from a different vehicle 
manufacturer than the first test vehicle, or if the aftermarket part 
applies to only one vehicle manufacturer, from a different engine 
family. Engine families are determined by the vehicle manufacturer or 
when certifying under 40 CFR part 86. Within that group, the second test 
vehicle is selected from the vehicle

[[Page 407]]

configurations with the heaviest equivalent test weight, and then, 
within that group, the configuration with the largest displacement 
engine. If a part applies to only one engine family then only the 
vehicle specified in paragraph (d)(5)(ii)(A), of this section, is 
required to be tested.
    (iii) The results of certification tests using the worst case 
vehicle selections made in this section shall only be applicable for 
configurations that are required to meet the same or less stringent 
(numerically higher) emission standards than those of the worst case 
configuration.
    (iv) The worst case test vehicle(s) selected for certification 
emission testing is(are) not required to meet Federal emission standards 
in its original configuration. However, each test vehicle shall have 
representative emissions performance that is close to the standards and 
have no obvious emission defects. Each test vehicle shall be tuned 
properly and set to the vehicle manufacturer's specifications before 
testing is performed. Any excessively worn or malfunctioning emission 
related part shall be repaired prior to testing.
    (e) Test part selection. Certification shall be based upon tests 
utilizing representative production aftermarket parts selected in a 
random manner in accordance with accepted statistical procedures.
    (f) Replacing original equipment parts. Installation of any 
certified aftermarket part shall not result in the removal or rendering 
inoperative of any original equipment emission related part other than 
the part(s) being replaced. Furthermore, installation of any certified 
aftermarket part shall not require the readjustment of any other 
emission related part to other than the vehicle manufacturer 
specifications, cause or contribute to an unreasonable risk to the 
public health, welfare or safety, or result in any additional range of 
parameter adjustability or accessibility to adjustment than that of the 
vehicle manufacturer's emission related parts.
    (g) Affects on vehicle on board diagnostic system. Installation of 
any certified aftermarket part shall not alter or render inoperative any 
feature of the on-board diagnostic system incorporated by the vehicle 
manufacturer. The certified part may integrate with the existing 
diagnostic system if it does not alter or render inoperative any 
features of the system. However, use of on-board diagnostics or warning 
indicators to alert the driver to part failure is not sufficient by 
itself to qualify the part for exemption from aging under paragraph 
(c)(4)(ii) of this section. The part manufacturer must demonstrate that 
the diagnostic and malfunction indicator system will routinely result in 
repair or replacement of the aftermarket part in use.

Sec.85.2116  Objections to certification.

    (a) At any time prior to the end of the 45-day period after a 
notification of intent to certify an aftermarket part is received as 
specified in Sec.85.2115, the MOD Director may notify the manufacturer 
of the aftermarket part that such aftermarket part may not be certified 
pending further investigation. The basis upon which this notification 
shall be made may include, but not be limited to, information or test 
results which indicate:

[[Page 409]]

    (1) Compliance with the applicable emission-critical parameters was 
not achieved or that the testing methods used to demonstrate compliance 
with the emission-critical parameters were inadequate;
    (2) The part is to be certified on the basis of emission testing, 
and the procedure used in such tests was not in compliance with those 
portions of the Federal Test Procedure not waived pursuant to Sec.
85.2114(d)(2).
    (3) Use of the certified part may cause a vehicle to exceed any 
applicable emission requirements;
    (4) The durability requirement of Sec.85.2114 has not been

Sec.85.2117  Warranty and dispute resolution.

    (a) Warranty. (1) As a condition of certification, the aftermarket 
part manufacturer shall warrant that if the certified part is properly 
installed it will not cause a vehicle to exceed Federal emission 
requirements as determined by an emission test approved by EPA under 
section 207(b)(1) of the Act. This aftermarket part warranty shall 
extend for the remaining performance warranty period of any vehicle on 
which the part is installed, or for the warranty period specified for an 
equivalent original equipment component, if this period is shorter than 
the remaining warranty period of the vehicle.
    (2) The aftermarket part manufacturer's minimum obligation under 
this warranty shall be to reimburse vehicle manufacturers for all 
reasonable expenses incurred as a result of honoring a valid emission 
performance warranty claim which arises because of the use of the 
certified aftermarket part.
    (3) The procedure used to process a certified aftermarket part 
warranty claim is as follows. The time requirements are in units of 
calendar days.
    (i) The vehicle manufacturer shall submit, by certified mail or 
another method by which date of receipt can be established, a bill for 
reasonable expenses incurred to the part manufacturer for reimbursement. 
Accompanying the bill shall be a letter to the part manufacturer with an 
explanation of how the certified part caused the failure and a copy of 
the warranty repair order or receipt establishing the date that the 
performance repair was initiated by the vehicle owner.
    (ii) The parts retained pursuant to Sec.85.2107(c)(1) shall be 
retained until the reimbursement process is resolved. The vehicle 
manufacturer shall store these parts or transfer these parts to the 
involved certified part manufacturer for storage. If the vehicle 
manufacturer transfers these parts to the certified part manufacturer, 
the part manufacturer shall retain these parts:
    (A) For at least one year from the date of repair involving these 
parts, if the part manufacturer does not receive a bill from the vehicle 
manufacturer within that time period, or
    (B) Until the claim reimbursement process has been resolved, if the 
part manufacturer receives a bill from the vehicle manufacturer within 
one year of the date of repair involving these parts.
    (iii) If the vehicle manufacturer transfers the parts retained 
pursuant to paragraph (a)(3)(ii) of this section to the part 
manufacturer, a bill shall be submitted to the part manufacturer within 
one year of the date of initiation of the actual repair by the vehicle 
owner. If this requirement is not met, the vehicle manufacturer shall 
forfeit all rights to the reimbursement provisions provided in this 
regulation.
    (iv) Storage costs are not reimbursable as part of a performance 
warranty claim.
    (b) Dispute resolution. (1) The part manufacturer shall respond to 
the vehicle manufacturer within 30 days of receipt of the bill by paying 
the claim or requesting a meeting to resolve any disagreement. A meeting 
shall occur within the next two week period. At this meeting the parties 
shall, in all good faith, attempt to resolve their disagreement. 
Discussions should be completed within 60 days of receipt of the bill 
for the warranty claim by the part manufacturer.
    (2) If the parties cannot resolve their disagreement within 60 days, 
either party may file for arbitration. Neither party may file for 
arbitration within 60 days unless both parties agree to seek arbitration 
prior to the end of the 60-day period. If, after 60 days, either party 
files, then both parties shall submit to arbitration.
    (3) This arbitration shall be carried out pursuant to the 
Arbitration Rules contained in appendix II of this subpart which are 
based on Commercial Arbitration Rules published by the American 
Arbitration Association, revised and in effect as of September 1, 1988. 
The Arbitration Rules detail the procedures to be followed by the 
parties and the arbitrator in resolving disputes under this section. 
They can be varied only with the agreement of both parties. If either 
involved manufacturer refuses to participate in the arbitration process, 
that party is treated as if it had lost the arbitration and is required 
to pay all reasonable expenses.

[[Page 411]]

    (4) Any party losing the arbitration has the right to resort to an 
appropriate federal district court or state court, subject to the 
established rules of that court regarding subject matter jurisdiction 
and personal jurisdiction.
    (5) If the vehicle manufacturer wins the arbitration, the part 
manufacturer must provide reimbursement in accordance with the 
arbitrator's award and decision. Such reimbursement must be made within 
30 days of the award and decision.
    (6)(i) If the part manufacturer refuses to pay a lost arbitration 
award, the involved part will be decertified pursuant to 40 CFR 85.2121, 
provided that if the part manufacturer resorts to a court of competent 
jurisdiction, decertification will be withheld pending the outcome of 
such judicial determination.
    (ii) In addition, under these circumstances, the vehicle 
manufacturer has the right to bring an enforcement action on the 
arbitration award and decision in the appropriate federal district court 
or state court, subject to the established rules of that court regarding 
subject matter jurisdiction and personal jurisdiction. If this court 
agrees with the arbitrator's award and decision, reimbursement shall be 
made within 30 days of the court's decision unless the court orders 
otherwise.

Light-off Time is then determined by recording the time required for the 
converter to reduce the outlet emissions (HC and CO) to 50% of the inlet 
emissions, on a volumetric concentration basis, measured from the step 
temperature change.
    (ii) Conversion efficiency measurements shall be obtained by passing 
stabilized-feed gas through the converter (at conditions specified 
above) and making simultaneous measurements of inlet and outlet emission 
volume concentrations. The conversion efficiency for CO and HC is then 
calculated.
    (iii) The particular conditions for which LOT and conversion 
efficiency are measured (i.e., exhaust mass flow rate, total 
hydrocarbons, carbon monoxide, hydrogen, oxygen, and converter inlet 
temperature) for the replacement converter and original equipment 
converter tests must not vary from one another by more than 10%.
    (b) Fresh and aged catalytic converters may be obtained by operating 
the converter on individual vehicle or engine application for which it 
is intended on the Federal Test Procedure road durability driving cycle. 
A fresh converter results when the converter has operated between 2000 
and 5000 miles or equivalent hours. An aged converter results when the 
converter has been operated for the warranted life of the original 
equipment converter.
    (c) Where one generic converter is intended to cover multiple 
vehicle or engine configurations, converter aging may be obtained per 
Paragraph (b) above, on a vehicle or engine which represents the 
greatest peak air flow of the group of vehicle configurations to be 
covered, and whose calibration and feed gas concentrations are 
representative of the vehicle or engine configurations being certified 
for.
    2. Other Considerations.
    (a) Replacement converter must fit within the width and length space 
envelope of the original equipment converter. Converter spacing from the 
underbody and for ground clearance must be the same or greater than the 
original equipment converter application.
    (b) Pressure drop measured between inlet and outlet pipe 
interconnecting points on the replacement converter shall be within 
25% of similar measurements for the original 
equipment converter being replaced, when measured at each of three flow 
conditions 50 SCFM, 100 SCFM, and 150 SCFM

[[Page 424]]

with a suitable fluid medium such as air. Maximum allowable exhaust gas 
leakage from the replacement coverter shall be 0.4 cubic feet per minute 
measured at 4.0 pounds per square inch differential. All measurements 
must be normalized to equal density conditions.
    (c) Converter skin temperature shall be measured during the 
converter efficiency test. The skin temperature for the replacement 
converter must equal or be less than that for the original equipment 
converter.

                      P. Air Cleaner Filter Element

    1. Test Procedures and Criteria.
    (a) Using test equipment and procedures specified in SAE-J726c, 
perform:
    (i) Air Flow and Pressure Drop Test (2.3) at 200 SCFM, record test 
conditions and pressure drop.
    (ii) Efficiency Test (2.4) to measure full life efficiency at 200 
SCFM to a total pressure drop of 9 inches of water, record test 
conditions and test duration from first to last addition of standard 
dust, weigh test element and absolute filter at end of test using three 
randomly selected original equipment air filter elements.
    (b) Perform tests as in (a) above, under conditions controlled to 
within 10% of the corresponding original equipment 
test conditions, for three randomly selected replacement air filter 
elements.
    (c) The replacement air filter element average recorded test 
results. The pressure drop in (i) and absolute filter weight in (ii) 
must be equal to or less than those average results for the original 
equipment test results. The replacement air filter averaged test results 
for element weight in (ii) must be equal to or larger than averaged 
result for the original equipment averaged test results.
    2. Durability Procedure.
    (a) After use in the intended vehicle or engine application for the 
recommended service interval, the replacement element shall evidence an 
increase in pressure drop (as measured in 1 (a)(i) above) equal to or 
less than that of the original equipment air filter element tested in 
the identical manner.

       Sec. Appendix II to Subpart V of Part 85--Arbitration Rules

                           Part A--Pre-Hearing

                  Section 1: Initiation of Arbitration

    Either party may commence an arbitration under these rules by filing 
at any regional office of the American Arbitration Association (the AAA) 
three copies of a written submission to arbitrate under these rules, 
signed by either party. It shall contain a statement of the matter in 
dispute, the amount of money involved, the remedy sought, and the 
hearing locale requested, together with the appropriate administrative 
fee as provided in the Administrative Fee Schedule of the AAA in effect 
at the time the arbitration is filed. The filing party shall notify the 
MOD Director in writing within 14 days of when it files for arbitration 
and provide the MOD Director with the date of receipt of the bill by the 
part manufacturer.
    Unless the AAA in its discretion determines otherwise and no party 
disagrees, the Expedited Procedures (as described in Part E of these 
Rules) shall be applied in any case where no disclosed claim or 
counterclaim exceeds $32,500, exclusive of interest and arbitration 
costs. Parties may also agree to the Expedited Procedures in cases 
involving claims in excess of $32,500.
    All other cases, including those involving claims not in excess of 
$32,500 where either party so desires, shall be administered in 
accordance with Parts A through D of these Rules.

                 Section 2: Qualification of Arbitrator

    Any arbitrator appointed pursuant to these Rules shall be neutral, 
subject to disqualification for the reasons specified in Section 6. If 
the parties specifically so agree in writing, the arbitrator shall not 
be subject to disqualification for said reasons.
    The term ``arbitrator'' in these rules refers to the arbitration 
panel, whether composed of one or more arbitrators.

      Section 3: Direct Appointment by Mutual Agreement of Parties

    The involved manufacturers should select a mutually-agreeable 
arbitrator through which they will resolve their dispute. This step 
should be completed within 90 days from the date of receipt of the 
warranty claim bill by the part manufacturer.

                    Section 4: Appointment From Panel

    If the parties have not appointed an arbitrator and have not 
provided any other method of appointment, the arbitrator shall be 
appointed in the following manner: 90 days from the date of receipt of 
the warranty claim bill by the part manufacturer, the AAA shall submit 
simultaneously to each party to the dispute an identical list of names 
of persons chosen from the National Panel of Commercial Arbitrators, 
established and maintained by the AAA.
    Each party to the dispute shall have ten days from the mailing date 
in which to cross off any names objected to, number the remaining names 
in order of preference, and return the list to the AAA. If a party does 
not return the list within the time specified, all persons named therein 
shall be deemed acceptable. From among the persons who

[[Page 425]]

have been approved on both lists, and in accordance with the designated 
order of mutual preference, the AAA shall invite the acceptance of an 
arbitrator to serve. If the parties fail to agree on any of the persons 
named, or if acceptable arbitrators are unable to act, or if for any 
other reason the appointment cannot be made from the submitted lists, 
the AAA shall have the power to make the appointment from among other 
members of the panel without the submission of additional lists.

  Section 5: Number of Arbitrators; Notice to Arbitrator of Appointment

    The dispute shall be heard and determined by one arbitrator, unless 
the AAA in its discretion, directs that a greater number of arbitrators 
be appointed.
    Notice of the appointment of the arbitrator shall be mailed to the 
arbitrator by the AAA, together with a copy of these rules, and the 
signed acceptance of the arbitrator shall be filed with the AAA prior to 
the opening of the first hearing.

              Section 6: Disclosure and Challenge Procedure

    Any person appointed as an arbitrator shall disclose to the AAA any 
circumstance likely to affect impartiality, including any bias or any 
financial or personal interest in the result of the arbitration or any 
past or present relationship with the parties or their representatives. 
Upon receipt of such information from the arbitrator or another source, 
the AAA shall communicate the information to the parties and, if it 
deems it appropriate to do so, to the arbitrator and others. Upon 
objection of a party to the continued service of an arbitrator, the AAA 
shall determine whether the arbitrator should be disqualified and shall 
inform the parties of its decision, which shall be conclusive.

                          Section 7: Vacancies

    If for any reason an arbitrator should be unable to perform the 
duties of the office, the AAA may, on proof satisfactory to it, declare 
the office vacant. Vacancies shall be filled in accordance with the 
applicable provisions of these rules.
    In the event of a vacancy in a panel of arbitrators after the 
hearings have commenced, the remaining arbitrator or arbitrators may 
continue with the hearing and determination of the controversy, unless 
the parties agree otherwise.

           Section 8: Interpretation and Application of Rules

    The arbitrator shall interpret and apply these rules insofar as they 
relate to the arbitrator's powers and duties. When there is more than 
one arbitrator and a difference arises among them concerning the meaning 
or application of these rules, it shall be decided by a majority vote. 
If that is unobtainable, either an arbitrator or a party may refer the 
question to the AAA for final decision. All other rules shall be 
interpreted and applied by the AAA.

      Section 9: Administrative Conference and Preliminary Hearing

    At the request of any party or at the discretion of the AAA, an 
administrative conference with the AAA and the parties and/or their 
representatives will be scheduled in appropriate cases to expedite the 
arbitration proceedings.
    In large or complex cases, at the request of any party or at the 
discretion of the arbitrator or the AAA, a preliminary hearing with the 
parties and/or their representatives and the arbitrator may be scheduled 
by the arbitrator to specify the issues to be resolved, stipulate to 
uncontested facts, and to consider any other matters that will expedite 
the arbitration proceedings. Consistent with the expedited nature of 
arbitration, the arbitrator may, at the preliminary hearing, establish 
(i) the extent of and the schedule for the production of relevant 
documents and other information, (ii) the identification of any 
witnesses to be called, and (iii) a schedule for further hearings to 
resolve the dispute.

                      Section 10: Fixing of Locale

    The parties may mutually agree on the locale where the arbitration 
is to be held. If any party requests that the hearing be held in a 
specific locale and the other party files no objection thereto within 
ten days after notice of the request has been mailed to it by the AAA, 
the locale shall be the one requested. If a party objects to the locale 
requested by the other party, the AAA shall have the power to determine 
the locale and its decision shall be final and binding.

                           Part B--The Hearing

               Section 1: Date, Time, and Place of Hearing

    The arbitrator shall set the date, time, and place for each hearing. 
The AAA shall mail to each party notice thereof at least ten days in 
advance, unless the parties by mutual agreement waive such notice or 
modify the terms thereof.

                        Section 2: Representation

    Any party may be represented by counsel or other authorized 
representative. A party intending to be so represented shall notify the 
other party and the AAA of the name and address of the representative at 
least three days prior to the date set for the hearing at which that 
person is first to appear.

[[Page 426]]

When such a representative initiates an arbitration or responds for a 
party, notice is deemed to have been given.

                    Section 3: Attendance at Hearings

    The arbitrator shall maintain the privacy of the hearings unless the 
law provides to the contrary. Representatives of the MOD director, and 
any persons having a direct interest in the arbitration are entitled to 
attend hearings. The arbitrator shall otherwise have the power to 
require the exclusion of any witness, other than a party or other 
essential person, during the testimony of any other witness. It shall be 
discretionary with the arbitrator to determine the propriety of the 
attendance of any other person.

                            Section 4: Oaths

    Before proceeding with the first hearing, each arbitrator may take 
an oath of office and, if required by law, shall do so. The arbitrator 
may require witnesses to testify under oath administered by any duly 
qualified person and, if it is required by law or requested by any 
party, shall do so.

                      Section 5: Majority Decision

    All decisions of the arbitrators must be by a majority. The award 
must also be made by a majority.

    Section 6: Order of Proceedings and Communication with Arbitrator

    A hearing shall be opened by the filing of the oath of the 
arbitrator, where required; by the recording of the date, time, and 
place of the hearing, and the presence of the arbitrator, the parties 
and their representatives, if any; and by the receipt by the arbitrator 
of the statement of the claim and the answering statement, if any.
    The arbitrator may, at the beginning of the hearing, ask for 
statements clarifying the issues involved. In some cases, part or all of 
the above will have been accomplished at the preliminary hearing 
conducted by the arbitrator pursuant to Part A Section 9 of these Rules.
    The complaining party shall then present evidence to support its 
claim. The defending party shall then present evidence supporting its 
defense. Witnesses for each party shall submit to questions or other 
examination. The arbitrator has the discretion to vary this procedure 
but shall afford a full and equal opportunity to all parties for the 
presentation of any material and relevant evidence.
    Exhibits, when offered by either party, may be received in evidence 
by the arbitrator.
    The names and addresses of all witnesses and a description of the 
exhibits in the order received shall be made a part of the record.
    There shall be no direct communication between the parties and an 
arbitrator other than at oral hearing, unless the parties and the 
arbitrator agree otherwise. Any other oral or written communication from 
the parties to the neutral arbitrator shall be directed to the AAA for 
transmittal to the arbitrator.

                           Section 7: Evidence

    The parties may offer such evidence as is relevant and material to 
the dispute and shall produce such evidence as the arbitrator may deem 
necessary to an understanding and determination of the dispute. An 
arbitrator or other person authorized by law to subpoena witnesses or 
documents may do so upon the request of any party or independently.
    The arbitrator shall be the judge of the relevance and materiality 
of the evidence offered, and conformity to legal rules of evidence shall 
not be necessary. All evidence shall be taken in the presence of all of 
the arbitrators and all of the parties, except where any of the parties 
is absent, in default, or has waived the right to be present.

Section 8: Evidence by Affidavit and Post-hearing Filing of Documents or 
                             Other Evidence

    The arbitrator may receive and consider the evidence of witnesses by 
affidavit, but shall give it only such weight as the arbitrator deems it 
entitled to after consideration of any objection made to its admission.
    If the parties agree or the arbitrator directs that documents or 
other evidence be submitted to the arbitrator after the hearing, the 
documents or other evidence shall be filed with the AAA for transmission 
to the arbitrator. All parties shall be afforded an opportunity to 
examine such documents or other evidence.

                      Section 9: Closing of Hearing

    The arbitrator shall specifically inquire of all parties whether 
they have any further proofs to offer or witnesses to be heard. Upon 
receiving negative replies or if satisfied that the record is complete, 
the arbitrator shall declare the hearing closed and a minute thereof 
shall be recorded. If briefs are to be filed, the hearing shall be 
declared closed as of the final date set by the arbitrator for the 
receipt of briefs. If documents are to be filed as provided for in Part 
B Section 9 and the date set for their receipt is later than that set 
for the receipt of briefs, the later date shall be the date of closing 
the hearing. The time limit within which the arbitrator is required to 
make the award shall commence to run, in the absence of other agreements 
by the parties, upon the closing of the hearing.

[[Page 427]]

                    Section 10: Reopening of Hearing

    The hearing may be reopened on the arbitrator's initiative, or upon 
application of a party, at any time before the award is made. The 
arbitrator may reopen the hearing and shall have 30 days from the 
closing of the reopened hearing within which to make an award.

                   Section 11: Waiver of Oral Hearing

    The parties may provide, by written agreement, for the waiver of 
oral hearings.

                       Section 12: Waiver of Rules

    Any party who proceeds with the arbitration after knowledge that any 
provision or requirement of these rules has not been complied with and 
who fails to state an objection thereto in writing, shall be deemed to 
have waived the right to object.

                     Section 13: Extensions of Time

    The parties may modify any period of time by mutual agreement. The 
AAA or the arbitrator may for good cause extend any period of time 
established by these rules, except the time for making the award. The 
AAA shall notify the parties of any extension.

                      Section 14: Serving of Notice

    Each party shall be deemed to have consented that any papers, 
notices, or process necessary or proper for the initiation or 
continuation of an arbitration under these rules; for any court action 
in connection therewith; or for the entry of judgment on any award made 
under these rules may be served on a party by mail addressed to the 
party or its representative at the last known address or by personal 
service, inside or outside the state where the arbitration is to be 
held, provided that reasonable opportunity to be heard with regard 
thereto has been granted to the party.
    The AAA and the parties may also use facsimile transmission, telex, 
telegram, or other written forms of electronic communication to give the 
notices required by these rules.

                       Part C--Award and Decision

                        Section 1: Time of Award

    The award shall be made promptly by the arbitrator and, unless 
otherwise agreed by the parties or specified by law, no later than 30 
days from the date of closing the hearing, or, if oral hearings have 
been waived, from the date of the AAA's transmittal of the final 
statements and proofs to the arbitrator.

                        Section 2: Form of Award

    The award shall be in writing and shall be signed by the arbitrator, 
or if a panel is utilized, a majority of the arbitrators. It shall be 
accompanied by a written decision which sets forth the reasons for the 
award. Both the award and the decision shall be filed by the arbitrator 
with the MOD Director.

                        Section 3: Scope of Award

    The arbitrator may grant to the vehicle manufacturer any repair 
expenses that he or she deems to be just and equitable.

                    Section 4: Award upon Settlement

    If the parties settle their dispute during the course of the 
arbitration, the arbitrator may set forth the terms of the agreed 
settlement in an award. Such an award is referred to as a consent award. 
The consent award shall be filed by the arbitrator with the MOD 
Director.

                 Section 5: Delivery of Award to Parties

    Parties shall accept as legal delivery of the award, the placing of 
the award, or a true copy thereof in the mail addressed to a party or 
its representative at the last known address, personal service of the 
award, or the filing of the award in any other manner that is permitted 
by law.

        Section 6: Release of Documents for Judicial Proceedings

    The AAA shall, upon the written request of a party, furnish to the 
party, at its expense, certified copies of any papers in the AAA's 
possession that may be required in judicial proceedings relating to the 
arbitration.

                        Part D--Fees and Expenses

                      Section 1: Administrative Fee

    The AAA shall be compensated for the cost of providing 
administrative services according to the AAA Administrative Fee Schedule 
and the AAA Refund Schedule. The Schedules in effect at the time the 
demand for arbitration or submission agreement is received shall be 
applicable.
    The administrative fee shall be advanced by the initiating party or 
parties, subject to final allocation at the end of the case.
    When a claim or counterclaim is withdrawn or settled, the refund 
shall be made in accordance with the Refund Schedule. The AAA may, in 
the event of extreme hardship on the part of any party, defer or reduce 
the administrative fee.

                           Section 2: Expenses

    The loser of the arbitration is liable for all arbitration expenses 
unless determined otherwise by the arbitrator.

[[Page 428]]

                       Section 3: Arbitrator's Fee

    An arrangement for the compensation of an arbitrator shall be made 
through discussions by the parties with the AAA and not directly between 
the parties and the arbitrator. The terms of compensation of arbitrators 
on a panel shall be identical.

                           Section 4: Deposits

    The AAA may require the parties to deposit in advance of any 
hearings such sums of money as it deems necessary to defray the expense 
of the arbitration, including the arbitrator's fee, if any, and shall 
render an accounting to the parties and return any unexpended balance at 
the conclusion of the case.

                      Part E--Expedited Procedures

                     Section 1: Notice by Telephone

    The parties shall accept all notices from the AAA by telephone. Such 
notices by the AAA shall subsequently be confirmed in writing to the 
parties. Should there be a failure to confirm in writing any notice 
hereunder, the proceeding shall nonetheless be valid if notice has, in 
fact, been given by telephone.

         Section 2: Appointment and Qualifications of Arbitrator

    The AAA shall submit simultaneously to each party an identical list 
of five proposed arbitrators drawn from the National Panel of Commercial 
Arbitrators, from which one arbitrator shall be appointed.
    Each party may strike two names from the list on a preemptory basis. 
The list is returnable to the AAA within seven days from the date of the 
AAA's mailing of the list to the parties.
    If for any reason the appointment of an arbitrator cannot be made 
from the list, the AAA may make the appointment from among other members 
of the panel without the submission of additional lists.
    The parties will be given notice by the AAA by telephone of the 
appointment of the arbitrator, who shall be subject to disqualification 
for the reasons specified in Part A, Section 6. The parties shall notify 
the AAA, by telephone, within seven days of any objection to the 
arbitrator appointed. Any objection by a party to the arbitrator shall 
be confirmed in writing to the AAA with a copy to the other party or 
parties.

               Section 3: Date, Time, and Place of Hearing

    The arbitrator shall set the date, time, and place of the hearing. 
The AAA will notify the parties by telephone, at least seven days in 
advance of the hearing date. Formal Notice of Hearing will be sent by 
the AAA to the parties and the MOD Director.

                         Section 4: The Hearing

    Generally, the hearing shall be completed within one day, unless the 
dispute is resolved by the submission of documents. The arbitrator, for 
good cause shown, may schedule an additional hearing to be held within 
seven days.

                        Section 5: Time of Award

    Unless otherwise agreed by the parties, the award shall be rendered 
not later than 14 days from the date of the closing of the hearing.

                    Section 6: Applicability of Rules

    Unless explicitly contradicted by the provisions of this part, 
provisions of other parts of the Rules apply to proceedings conducted 
under this part.

[54 FR 32593, Aug. 8, 1989, as amended at 70 FR 40432, July 13, 2005]



   Subpart W_Emission Control System Performance Warranty Short Tests

    Source: 79 FR 23684, Apr. 28, 2014, unless otherwise noted.



Sec.85.2201  Applicability.

    (a) This subpart describes the test provisions to be employed in 
conjunction with the Emissions Performance Warranty in subpart V of this 
part. These provisions generally rely on a vehicle's onboard diagnostic 
system (OBD) to indicate whether a vehicle passes or fails the test.
    (b) The provisions of this subpart may be used to establish warranty 
eligibility for light-duty vehicles, light-duty trucks, and medium-duty 
passenger vehicles when tested during the useful life as prescribed in 
subpart V of this part.



Sec.85.2207  Onboard diagnostic test standards.

    (a) A vehicle shall fail the OBD test if it is a 1996 or newer 
vehicle and the vehicle connector is missing, has been tampered with, or 
is otherwise inoperable.
    (b) A vehicle shall fail the OBD test if the malfunction indicator 
light (MIL) is commanded to be illuminated and it is not visually 
illuminated according to visual inspection.

[[Page 429]]

    (c) A vehicle shall fail the OBD test if the MIL is commanded to be 
illuminated for one or more diagnostic trouble codes (DTCs), as 
described in 40 CFR 86.1806.



Sec.85.2222  Onboard diagnostic test procedures.

    The test sequence for the OBD inspection shall consist of the 
following steps:
    (a) The OBD inspection shall be conducted with the key-on/engine 
running, with the exception of inspecting for MIL illumination as 
required in paragraph (d)(4) of this section, during which the 
inspection shall be conducted with the key-on/engine off.
    (b) The inspector shall locate the vehicle connector and plug the 
test system into the connector.
    (c) The test system shall send a Mode $01, PID $01 request in 
accordance with 40 CFR 86.1806 to determine the OBD evaluation status. 
The test system shall determine what monitors are supported by the OBD 
system, and perform the readiness evaluation for applicable monitors in 
accordance with the requirements and specifications in 40 CFR 86.1806.
    (1) Coincident with the beginning of mandatory testing, repair, and 
retesting based upon the OBD test, if the readiness evaluation indicates 
that any onboard tests are not complete, the customer shall be 
instructed to return after the vehicle has been run under conditions 
that allow completion of all applicable onboard tests. If the readiness 
evaluation again indicates that any onboard test is not complete, the 
vehicle shall be failed.
    (2) An exception to paragraph (c)(1) of this section is allowed for 
MY 1996 to MY 2000 vehicles, inclusive, with two or fewer unset 
readiness monitors, and for MY 2001 and newer vehicles with no more than 
one unset readiness monitor. Vehicles from those model years which would 
otherwise pass the OBD inspection, but for the unset readiness code in 
question, may be issued a passing certificate without being required to 
operate the vehicle in such a way as to activate those particular 
monitors. Vehicles from those model years with an unset readiness code 
that also have a DTC stored resulting in an illuminated MIL must be 
failed, though setting the unset readiness flag in question shall not be 
a prerequisite for passing the retest.
    (d) The test system shall evaluate the MIL status bit and record 
status information in the vehicle test record.
    (1) If the MIL status bit indicates that the MIL has been commanded 
to be illuminated, the test system shall send a Mode $03 request in 
accordance with 40 CFR 86.1806 to determine the stored DTCs. The system 
shall repeat this cycle until the number of codes reported equals the 
number expected based on the Mode $01 response. All DTCs resulting in 
MIL illumination shall be recorded in the vehicle test record and the 
vehicle shall fail the OBD inspection.
    (2) If the MIL bit is not commanded to be illuminated the vehicle 
shall pass the OBD inspection, even if DTCs are present.
    (3) If the MIL bit is commanded to be illuminated, the inspector 
shall visually inspect the MIL to determine if it is illuminated. If the 
MIL is commanded to be illuminated but is not, the vehicle shall fail 
the OBD inspection.
    (4) If the MIL does not illuminate at all when the vehicle is in the 
key-on/engine-off condition, the vehicle shall fail the OBD inspection, 
even if no DTCs are present and the MIL has not been commanded on.



Sec.85.2223  Onboard diagnostic test report.

    (a) Motorists whose vehicles fail the OBD test described in Sec.
85.2222 shall be provided with the OBD test results, including the codes 
retrieved, the name of the component or system associated with each DTC, 
the status of the MIL illumination command, and the customer alert 
statement as stated in paragraph (b) of this section.
    (b) In addition to any codes that were retrieved, the test report 
shall include the following language:
    Your vehicle's computerized self-diagnostic system (OBD) registered 
the faults listed below. The faults are probably an indication of a 
malfunction of an emission component. However, multiple and/or seemingly 
unrelated faults

[[Page 430]]

may be an indication of an emission-related problem that occurred 
previously, but upon further evaluation by the OBD system was determined 
to be only temporary. Therefore, proper diagnosis by a qualified 
technician is required to positively identify the source of any 
emission-related problem.



Sec.85.2231  Onboard diagnostic test equipment requirements.

    (a) The test system interface to the vehicle shall include a plug 
that conforms to the requirements and specifications of 40 CFR 86.1806.
    (b) The test system shall be capable of communicating with the 
standard data link connector of vehicles with certified OBD systems.
    (c) The test system shall be capable of checking for OBD monitors 
and the evaluation status of supported monitors (test complete/test not 
complete) in Mode $01 PID $01, as well as be able to request the DTCs, 
consistent with the requirements and specifications of 40 CFR 86.1806.



  Subpart X_Determination of Model Year for Motor Vehicles and Engines 
 Used in Motor Vehicles Under Section 177 and Part A of Title II of the 
                              Clean Air Act

    Source: 60 FR 4738, Jan. 24, 1995, unless otherwise noted.



Sec.85.2301  Applicability.

    The definitions provided by this subpart are effective February 23, 
1995 and apply to all light-duty motor vehicles and trucks, heavy-duty 
motor vehicles and heavy-duty engines used in motor vehicles, and on-
highway motorcycles as such vehicles and engines are regulated under 
section 177 and Title II part A of the Clean Air Act.

    Effective Date Note: At 86 FR 34364, June 29, 2021, Sec.85.2301 
was revised, effective July 29, 2021.



Sec.85.2302  Definition of model year.

    Model year means the manufacturer's annual production period (as 
determined under Sec.85.2304) which includes January 1 of such 
calendar year, provided, that if the manufacturer has no annual 
production period, the term ``model year'' shall mean the calendar year.



Sec.85.2303  Duration of model year.

    A specific model year must always include January 1 of the calendar 
year for which it is designated and may not include a January 1 of any 
other calendar year. Thus, the maximum duration of a model year is one 
calendar year plus 364 days.



Sec.85.2304  Definition of production period.

    (a) The ``annual production period'' for all models within an engine 
family of light-duty motor vehicles, heavy-duty motor vehicles and 
engines, and on-highway motorcycles begins either: when any vehicle or 
engine within the engine family is first produced; or on January 2 of 
the calendar year preceding the year for which the model year is 
designated, whichever date is later. The annual production period ends 
either: When the last such vehicle or engine is produced; or on December 
31 of the calendar year for which the model year is named, whichever 
date is sooner.
    (b) The date when a vehicle or engine is first produced is the ``Job 
1 date,'' which is defined as that calendar date on which a manufacturer 
completes all manufacturing and assembling processes necessary to 
produce the first saleable unit of the designated model which is in all 
material respects the same as the vehicle or engine described in the 
manufacturer's application for certification. The ``Job 1 date'' may be 
a date earlier in time than the date on which the certificate of 
conformity is issued.



Sec.85.2305  Duration and applicability of certificates of conformity.

    (a) Except as provided in paragraph (b) of this section, a 
certificate of conformity is deemed to be effective and cover the 
vehicles or engines named in such certificate and produced during the 
annual production period, as defined in Sec.85.2304.
    (b) Section 203 of the Clean Air Act prohibits the sale, offering 
for sale, delivery for introduction into commerce, and introduction into 
commerce, of

[[Page 431]]

any new vehicle or engine not covered by a certificate of conformity 
unless it is an imported vehicle exempted by the Administrator or 
otherwise authorized jointly by EPA and U.S. Customs Service 
regulations. However, the Act does not prohibit the production of 
vehicles or engines without a certificate of conformity. Vehicles or 
engines produced prior to the effective date of a certificate of 
conformity, as defined in paragraph (a) of this section, may also be 
covered by the certificate if the following conditions are met:
    (1) The vehicles or engines conform in all material respects to the 
vehicles or engines described in the application for the certificate of 
conformity:
    (2) The vehicles or engines are not sold, offered for sale, 
introduced into commerce, or delivered for introduction into commerce 
prior to the effective date of the certificate of conformity;
    (3) The Agency is notified prior to the beginning of production when 
such production will start, and the Agency is provided full opportunity 
to inspect and/or test the vehicles during and after their production; 
for example, the Agency must have the opportunity to conduct selective 
enforcement auditing production line testing as if the vehicles had been 
produced after the effective date of the certificate.
    (c) New vehicles or engines imported by an original equipment 
manufacturer after December 31 of the calendar year for which the model 
year was named are still covered by the certificate of conformity as 
long as the production of the vehicle or engine was completed before 
December 31 of that year. This paragraph does not apply to vehicles that 
may be covered by certificates held by independent commercial importers 
unless specifically approved by EPA.
    (d) Vehicles or engines produced after December 31 of the calendar 
year for which the model year is named are not covered by the 
certificate of conformity for that model year. A new certificate of 
conformity demonstrating compliance with currently applicable standards 
must be obtained for these vehicles or engines even if they are 
identical to vehicles or engines built before December 31.
    (e) The extended coverage period described here for a certificate of 
conformity (i.e., up to one year plus 364 days) is primarily intended to 
allow flexibility in the introduction of new models. Under no 
circumstances should it be interpreted that existing models may ``skip'' 
yearly certification by pulling ahead the production of every other 
model year.

Sec.86.000-24  Test vehicles and engines.

    (a) [Reserved.
    (b) introductory text [Reserved]
    (b)(1)(i) Vehicles are chosen to be operated and tested for emission 
data based upon engine family groupings.

[[Page 444]]

Within each engine family, one test vehicle is selected. If air 
conditioning is projected to be available on any vehicles within the 
engine family, the Administrator will limit selections to engine codes 
which have air conditioning available and will require that any vehicle 
selected under this section has air conditioning installed and 
operational. The Administrator selects as the test vehicle the vehicle 
with the heaviest equivalent test weight (including options) within the 
family which meets the air conditioning eligibility requirement 
discussed earlier in this section. If more than one vehicle meets this 
criterion, then within that vehicle grouping, the Administrator selects, 
in the order listed, the highest road-load power, largest displacement, 
the transmission with the highest numerical final gear ratio (including 
overdrive), the highest numerical axle ratio offered in that engine 
family, and the maximum fuel flow calibration.
    (ii) The Administrator selects one additional test vehicle from 
within each engine family. The additional vehicle selected is the 
vehicle expected to exhibit the highest emissions of those vehicles 
remaining in the engine family. The selected vehicle will include an air 
conditioning engine code unless the Administrator chooses a worst 
vehicle configuration that is not available with air conditioning. If 
all vehicles within the engine family are similar, the Administrator may 
waive the requirements of this paragraph.
    (b)(1)(iii)-(b)(1)(vi) [Reserved]
    (c)-(f) [Reserved]
    (g)(1)-(2) [Reserved]
    (g)(3) Except for air conditioning, where it is expected that 33 
percent or less of a carline, within an engine-system combination, will 
be equipped with an item (whether that item is standard equipment or an 
option) that can reasonably be expected to influence emissions, that 
item may not be installed on any emission data vehicle or durability 
data vehicle of that carline within that engine-system combination, 
unless that item is standard equipment on that vehicle or specifically 
required by the Administrator.
    (4) Air conditioning must be installed and operational on any 
emission data vehicle of any vehicle configuration that is projected to 
be available with air conditioning regardless of the rate of 
installation of air conditioning within the carline. Section 86.096-
24(g) (1) and (2) and paragraph (g)(3) of this section will be used to 
determine whether the weight of the air conditioner will be included in 
equivalent test weight calculations for emission testing.

Sec.86.004-2  Definitions.

    The definitions of Sec.86.001-2 continue to apply to 2001 and 
later model year vehicles. The definitions listed in this section apply 
beginning with the 2004 model year.
    Ambulance has the meaning given in Sec.86.1803.
    Defeat device means an auxiliary emission control device (AECD) that 
reduces the effectiveness of the emission control system under 
conditions which may reasonably be expected to be encountered in normal 
vehicle operation and use, unless:
    (1) Such conditions are substantially included in the applicable 
Federal emission test procedure for heavy-duty vehicles and heavy-duty 
engines described in subpart N of this part;
    (2) The need for the AECD is justified in terms of protecting the 
vehicle against damage or accident;
    (3) The AECD does not go beyond the requirements of engine starting; 
or
    (4) The AECD applies only for engines that will be installed in 
emergency vehicles, and the need is justified in terms of preventing the 
engine from losing speed, torque, or power due abnormal conditions of 
the emission control system, or in terms of preventing such abnormal 
conditions from occurring, during operation related to emergency 
response. Examples of such abnormal conditions may include excessive 
exhaust backpressure from an overloaded particulate trap, and running 
out of diesel exhaust fluid for engines that rely on urea-based 
selective catalytic reduction.
    Diesel exhaust fluid (DEF) means a liquid reducing agent (other than 
the engine fuel) used in conjunction with selective catalytic reduction 
to reduce NOX emissions. Diesel exhaust fluid is generally 
understood to be an aqueous solution of urea conforming to the 
specifications of ISO 22241.
    Emergency vehicle has the meaning given in 40 CFR 1037.801.
    Fire truck has the meaning given in Sec.86.1803.
    U.S.-directed production means the engines and/or vehicles (as 
applicable) produced by a manufacturer for which the manufacturer has 
reasonable assurance that sale was or will be made to ultimate 
purchasers in the United States, excluding engines and/or vehicles that 
are certified to state emission standards different than the emission 
standards in this part.
    Useful life means:
    (1) For light-duty vehicles, and for light light-duty trucks not 
subject to the Tier 0 standards of Sec.86.094-9(a), intermediate 
useful life and/or full useful life. Intermediate useful life is a 
period of use of 5 years or 50,000 miles, whichever occurs first. Full 
useful life is a period of use of 10 years or 100,000 miles, whichever 
occurs first, except as otherwise noted in Sec.86.094-9. The useful 
life of evaporative and/or refueling emission control systems on the 
portion of these vehicles subject to the evaporative emission test 
requirements of Sec.86.130-96, and/or the refueling emission test 
requirements of Sec.86.151-98, is defined as a period of use of 10 
years or 100,000 miles, whichever occurs first.
    (2) For light light-duty trucks subject to the Tier 0 standards of 
Sec.86.094-9(a), and for heavy light-duty truck engine families, 
intermediate and/or full useful life. Intermediate useful life is a 
period of use of 5 years or 50,000 miles, whichever occurs first. Full 
useful life

[[Page 448]]

is a period of use of 11 years or 120,000 miles, whichever occurs first. 
The useful life of evaporative emission and/or refueling control systems 
on the portion of these vehicles subject to the evaporative emission 
test requirements of Sec.86.130-96, and/or the refueling emission test 
requirements of Sec.86.151-98, is also defined as a period of 11 years 
or 120,000 miles, whichever occurs first.
    (3) For an Otto-cycle HDE family:
    (i) For hydrocarbon and carbon monoxide standards, a period of use 
of 10 years or 110,000 miles, whichever first occurs.

years or 110,000 miles, whichever first occurs.
    (iii) For the portion of evaporative emission control systems 
subject to the evaporative emission test requirements of Sec.86.1230-
96, a period of use of 10 years or 110,000 miles, whichever first 
occurs.
    (4) For a diesel HDE family:
    (i) For light heavy-duty diesel engines, for carbon monoxide, 
particulate, and oxides of nitrogen plus non-methane hydrocarbons 
emissions standards, a period of use of 10 years or 110,000 miles, 
whichever first occurs.
    (ii) For medium heavy-duty diesel engines, for carbon monoxide, 
particulate, and oxides of nitrogen plus non-methane hydrocarbons 
emission standards, a period of use of 10 years or 185,000 miles, 
whichever first occurs.
    (iii) For heavy heavy-duty diesel engines, for carbon monoxide, 
particulate, and oxides of nitrogen plus non-methane hydrocarbon 
emissions standards, a period of use of 10 years or 435,000 miles, or 
22,000 hours, whichever first occurs, except as provided in paragraphs 
(4)(iv) and (4)(v) of this definition.
    (iv) The useful life limit of 22,000 hours in paragraph (4)(iii) of 
this definition is effective as a limit to the useful life only when an 
accurate hours meter is provided by the manufacturer with the engine and 
only when such hours meter can reasonably be expected to operate 
properly over the useful life of the engine.
    (v) For an individual engine, if the useful life hours limit of 
22,000 hours is reached before the engine reaches 10 years or 100,000 
miles, the useful life shall become 10 years or 100,000 miles, whichever 
occurs first, as required under Clean Air Act section 202(d).
    (5) As an option for both light-duty trucks under certain conditions 
and HDE families, an alternative useful life period may be assigned by 
the Administrator under the provisions of Sec.86.094-21(f).
    Warranty period, for purposes of HDE emissions defect warranty and 
emissions performance warranty, shall be a period of 5 years/50,000 
miles, whichever occurs first, for Otto-cycle HDEs and light heavy-duty 
diesel engines. For all other heavy-duty diesel engines the 
aforementioned period shall be 5 years/100,000 miles, whichever occurs 
first. However, in no case may this period be less than the basic 
mechanical warranty period that the manufacturer provides (with or 
without additional charge) to the purchaser of the engine. Extended 
warranties on select parts do not extend the emissions warranty 
requirements for the entire engine but only for those parts. In cases 
where responsibility for an extended warranty is shared between the 
owner and the manufacturer, the emissions warranty shall also be shared 
in the same manner as specified in the warranty agreement.

Sec.86.004-15  NOX plus NMHC and particulate averaging, trading, 
and banking for heavy-duty engines.

    (a)(1) Heavy-duty engines eligible for NOX plus NMHC and 
particulate averaging, trading and banking programs are described in the 
applicable emission standards sections in this subpart. All heavy-duty 
engine families which include any engines labeled for use in clean-fuel 
vehicles as specified in 40 CFR part 88 are not eligible for these 
programs. For manufacturers not selecting Options 1 or 2 contained in 
Sec.86.005-10(f), the ABT program requirements contained in Sec.
86.000-15 apply for 2004 model year Otto-cycle engines, rather than the 
provisions contained in this Sec.86.004-15. Participation in these 
programs is voluntary.
    (2)(i) Engine families with FELs exceeding the applicable standard 
shall obtain emission credits in a mass amount sufficient to address the 
shortfall. Credits may be obtained from averaging, trading, or banking, 
within the averaging set restrictions described in this section.
    (ii) Engine families with FELs below the applicable standard will 
have emission credits available to average, trade, bank or a combination 
thereof. Credits may not be used for averaging or trading to offset 
emissions that exceed an FEL. Credits may not be used to remedy an in-
use nonconformity determined by a Selective Enforcement Audit or by 
recall testing. However, credits may be used to allow subsequent 
production of engines for the family in question if the manufacturer 
elects to recertify to a higher FEL.
    (b) Participation in the NOX plus NMHC and/or particulate 
averaging, trading, and banking programs shall be done as follows:
    (1) During certification, the manufacturer shall:
    (i) Declare its intent to include specific engine families in the 
averaging, trading and/or banking programs. Separate declarations are 
required for each program and for each pollutant (i.e., NOX 
plus NMHC, and particulate).
    (ii) Declare an FEL for each engine family participating in one or 
more of these two programs.
    (A) The FEL must be to the same level of significant digits as the 
emission standard (one-tenth of a gram per brake horsepower-hour for 
NOX plus NMHC emissions and one-hundredth of a gram per brake 
horsepower-hour for particulate emissions).
    (B) In no case may the FEL exceed the upper limit prescribed in the 
section concerning the applicable heavy-duty engine NOX plus 
NMHC and particulate emission standards.
    (iii) Calculate the projected emission credits (positive or 
negative) based on quarterly production projections for each 
participating family and for each pollutant, using the applicable 
equation in paragraph (c) of this section and the applicable factors for 
the specific engine family.
    (iv)(A) Determine and state the source of the needed credits 
according to quarterly projected production for engine families 
requiring credits for certification.
    (B) State where the quarterly projected credits will be applied for 
engine families generating credits.
    (C) Credits may be obtained from or applied to only engine families 
within the same averaging set as described in paragraph (d) or (e) of 
this section. Credits available for averaging, trading, or banking as 
defined in Sec.86.090-2, may be applied exclusively to a given engine 
family, or reserved as defined in Sec.86.091-2.
    (2) Based on this information each manufacturer's certification 
application must demonstrate:
    (i) That at the end of model year production, each engine family has 
a net emissions credit balance of zero or

[[Page 452]]

more using the methodology in paragraph (c) of this section with any 
credits obtained from averaging, trading or banking.
    (ii) The source of the credits to be used to comply with the 
emission standard if the FEL exceeds the standard, or where credits will 
be applied if the FEL is less than the emission standard. In cases where 
credits are being obtained, each engine family involved must state 
specifically the source (manufacturer/engine family) of the credits 
being used. In cases where credits are being generated/supplied, each 
engine family involved must state specifically the designated use 
(manufacturer/engine family or reserved) of the credits involved. All 
such reports shall include all credits involved in averaging, trading or 
banking.
    (3) During the model year manufacturers must:
    (i) Monitor projected versus actual production to be certain that 
compliance with the emission standards is achieved at the end of the 
model year.
    (ii) Provide the end-of-model year reports required under Sec.
86.001-23.
    (iii) For manufacturers participating in emission credit trading, 
maintain the quarterly records required under Sec.86.091-7(c)(8).
    (4) Projected credits based on information supplied in the 
certification application may be used to obtain a certificate of 
conformity. However, any such credits may be revoked based on review of 
end-of-model year reports, follow-up audits, and any other compliance 
measures deemed appropriate by the Administrator.
    (5) Compliance under averaging, banking, and trading will be 
determined at the end of the model year. Engine families without an 
adequate amount of NOX. NOX plus NMHC, and/or 
particulate emission credits will violate the conditions of the 
certificate of conformity. The certificates of conformity may be voided 
ab initio for engine families exceeding the emission standard.
    (6) If EPA or the manufacturer determines that a reporting error 
occurred on an end-of-year report previously submitted to EPA under this 
section, the manufacturer's credits and credit calculations will be 
recalculated. Erroneous positive credits will be void. Erroneous 
negative balances may be adjusted by EPA for retroactive use.
    (i) If EPA review of a manufacturer's end-of-year report indicates a 
credit shortfall, the manufacturer will be permitted to purchase the 
necessary credits to bring the credit balance for that engine family to 
zero, using the discount specified in paragraph (c)(1) of this section 
on the ratio of credits purchased for every credit needed to bring the 
balance to zero. If sufficient credits are not available to bring the 
credit balance for the family in question to zero, EPA may void the 
certificate for that engine family ab initio.
    (ii) If within 180 days of receipt of the manufacturer's end-of-year 
report, EPA review determines a reporting error in the manufacturer's 
favor (i.e., resulting in a positive credit balance) or if the 
manufacturer discovers such an error within 180 days of EPA receipt of 
the end-of-year report, the credits will be restored for use by the 
manufacturer.
    (c)(1) For each participating engine family, NOX plus 
NMHC, and particulate emission credits (positive or negative) are to be 
calculated according to one of the following equations and rounded, in 
accordance with ASTM E29-93a (incorporated by reference at Sec.86.1), 
to the nearest one-tenth of a Megagram (Mg). Consistent units are to be 
used throughout the equation.
    (i) For determining credit need for all engine families and credit 
availability for engine families generating credits for averaging 
programs only:

Emission credits = (Std - FEL) x (CF) x (UL) x (Production) x 
(10-6)

    (ii) For determining credit availability for engine families 
generating credits for trading or banking programs:

Emission credits = (Std - FEL) x (CF) x (UL) x (Production) x 
(10-6) x (Discount)

    (iii) For purposes of the equation in paragraphs (c)(1)(i) and (ii) 
of this section:

Std = the current and applicable heavy-duty engine NOX plus 
          NMHC or particulate emission standard in grams per brake 
          horsepower hour or grams per Megajoule.

[[Page 453]]

FEL = the NOX plus NMHC, or particulate family emission limit 
          for the engine family in grams per brake horsepower hour or 
          grams per Megajoule.
CF = a transient cycle conversion factor in BHP-hr/mi or MJ/mi, as given 
          in paragraph (c)(2) of this section.
UL = the useful life described in Sec.86.004-2, or alternative life as 
          described in Sec.86.004-21(f), for the given engine family 
          in miles.
Production = the number of engines produced for U.S. sales within the 
          given engine family during the model year. Quarterly 
          production projections are used for initial certification. 
          Actual production is used for end-of-year compliance 
          determination.
Discount = a one-time discount applied to all credits to be banked or 
          traded within the model year generated. Except as otherwise 
          allowed in paragraphs (k) and (l) of this section, the 
          discount applied here is 0.9. Banked credits traded in a 
          subsequent model year will not be subject to an additional 
          discount. Banked credits used in a subsequent model year's 
          averaging program will not have the discount restored.

    (2)(i) The transient cycle conversion factor is the total 
(integrated) cycle brake horsepower-hour or Megajoules, divided by the 
equivalent mileage of the applicable transient cycle. For Otto-cycle 
heavy-duty engines, the equivalent mileage is 6.3 miles. For diesel 
heavy-duty engines, the equivalent mileage is 6.5 miles.
    (ii) When more than one configuration is chosen by EPA to be tested 
in the certification of an engine family (as described in Sec.86.085-
24), the conversion factor used is to be based upon a production 
weighted average value of the configurations in an engine family to 
calculate the conversion factor.
    (d) Averaging sets for NOX plus NMHC emission credits. The averaging 
and trading of NOX plus NMHC emission credits will only be 
allowed between heavy-duty engine families in the same averaging set. 
The averaging sets for the averaging and trading of NOX plus 
NMHC emission credits for heavy-duty engines are defined as follows:
    (1) For NOX + NMHC credits from Otto-cycle heavy-duty 
engines:
    (i) Otto-cycle heavy-duty engines constitute an averaging set. 
Averaging and trading among all Otto-cycle heavy-duty engine families is 
allowed. There are no subclass restrictions.
    (ii) Otto-cycle heavy-duty vehicles certified under the chassis-
based provisions of subpart S of this part may not average or trade with 
heavy-duty Otto-cycle engines except as allowed in Sec.86.1817-05(o).
    (2) For NOX plus NMHC credits from diesel-cycle heavy-
duty engines:
    (i) Each of the three primary intended service classes for heavy-
duty diesel engines, as defined in Sec.86.004-2, constitute an 
averaging set. Averaging and trading among all diesel-cycle engine 
families within the same primary service class is allowed.
    (ii) Urban buses are treated as members of the primary intended 
service class where they otherwise would fall.
    (e) Averaging sets for particulate emission credits. The averaging 
and trading of particulate emission credits will only be allowed between 
diesel cycle heavy-duty engine families in the same averaging set. The 
averaging sets for the averaging and trading of particulate emission 
credits for diesel cycle heavy-duty engines are defined as follows:
    (1) Engines intended for use in urban buses constitute a separate 
averaging set from all other heavy-duty engines. Averaging and trading 
between diesel cycle bus engine families is allowed.
    (2) For heavy-duty engines, exclusive of urban bus engines, each of 
the three primary intended service classes for heavy-duty diesel cycle 
engines, as defined in Sec.86.004-2, constitute an averaging set. 
Averaging and trading between diesel-cycle engine families within the 
same primary service class is allowed.
    (3) Otto cycle engines may not participate in particulate averaging, 
trading, or banking.
    (f) Banking of NOX plus NMHC, and particulate emission credits--(1) 
Credit deposits. (i) NOX plus NMHC, and particulate emission 
credits may be banked from engine families produced in any model year.
    (ii) Manufacturers may bank credits only after the end of the model 
year and after actual credits have been reported to EPA in the end-of-
year report. During the model year and before submittal of the end-of-
year report, credits originally designated in the certification process 
for banking will

[[Page 454]]

be considered reserved and may be redesignated for trading or averaging.
    (2) Credit withdrawals. (i) NOX plus NMHC and particulate 
credits generated in 2004 and later model years do not expire. 
NOX plus NMHC credits generated by Otto-cycle engines in the 
2003 model year for manufacturers selecting Option 1 contained in Sec.
86.005-10(f)(1) also do not expire.
    (ii) Manufacturers withdrawing banked NOX plus NMHC, and/
or particulate credits shall indicate so during certification and in 
their credit reports, as described in Sec.86.091-23.
    (3) Use of banked emission credits. The use of banked credits shall 
be within the averaging set and other restrictions described in 
paragraphs (d) and (e) of this section, and only for the following 
purposes:
    (i) Banked credits may be used in averaging, or in trading, or in 
any combination thereof, during the certification period. Credits 
declared for banking from the previous model year but not reported to 
EPA may also be used. However, if EPA finds that the reported credits 
can not be proven, they will be revoked and unavailable for use.
    (ii) Banked credits may not be used for NOX plus NMHC or 
particulate averaging and trading to offset emissions that exceed an 
FEL. Banked credits may not be used to remedy an in-use nonconformity 
determined by a Selective Enforcement Audit or by recall testing. 
However, banked credits may be used for subsequent production of the 
engine family if the manufacturer elects to recertify to a higher FEL.
    (iii) NOX credits banked under paragraph Sec.86.098-
15(j) or Sec.86.000-15(k) may be used in place of NOX plus 
NMHC credits in 2004 and later model years provided that they are used 
in the correct averaging set. NOX credits banked under 
paragraph Sec.86.000-15(k) may also be used in place of NOX 
plus NMHC credits in the 2003 model year for manufacturers selecting 
Option 1 contained in Sec.86.005-10(f)(1), provided that they are used 
in the correct averaging set.
    (iv) Except for early credits banked under Sec.86.000-15(k), 
NOX credits banked in accordance with Sec.86.000-15 may not 
be used to meet the Otto-cycle engine standards contained in Sec.
86.005-10.
    (g)(1) This paragraph (g) assumes NOX plus NMHC, and 
particulate nonconformance penalties (NCPs) will be available for the 
2004 and later model year HDEs.
    (2) Engine families using NOX plus NMHC and/or 
particulate NCPs but not involved in averaging:
    (i) May not generate NOX plus NMHC or particulate credits 
for banking and trading.
    (ii) May not use NOX plus NMHC or particulate credits 
from banking and trading.
    (3) If a manufacturer has any engine family to which application of 
NCPs and banking and trading credits is desired, that family must be 
separated into two distinct families. One family, whose FEL equals the 
standard, must use NCPs only while the other, whose FEL does not equal 
the standard, must use credits only.
    (4) If a manufacturer has any engine family in a given averaging set 
which is using NOX plus NMHC and/or particulate NCPs, none of 
that manufacturer's engine families in that averaging set may generate 
credits for banking and trading.
    (h) In the event of a negative credit balance in a trading 
situation, both the buyer and the seller would be liable.
    (i) Certification fuel used for credit generation must be of a type 
that is both available in use and expected to be used by the engine 
purchaser. Therefore, upon request by the Administrator, the engine 
manufacturer must provide information acceptable to the Administrator 
that the designated fuel is readily available commercially and would be 
used in customer service.
    (j) Credit apportionment. At the manufacturer's option, credits 
generated under the provisions described in this section may be sold to 
or otherwise provided to another party for use in programs other than 
the averaging, trading and banking program described in this section.
    (1) The manufacturer shall pre-identify two emission levels per 
engine family for the purposes of credit apportionment. One emission 
level shall be the FEL and the other shall be the level of the standard 
that the engine family is required to certify to under Sec.86.005-10 
or Sec.86.004-11. For each engine

[[Page 455]]

family, the manufacturer may report engine sales in two categories, 
``ABT-only credits'' and ``nonmanufacturer-owned credits''.
    (i) For engine sales reported as ``ABT-only credits'', the credits 
generated must be used solely in the ABT program described in this 
section.
    (ii) The engine manufacturer may declare a portion of engine sales 
``nonmanufacturer-owned credits'' and this portion of the credits 
generated between the standard and the FEL, based on the calculation in 
(c)(1) of this section, would belong to the engine purchaser. For ABT, 
the manufacturer may not generate any credits for the engine sales 
reported as ``nonmanufacturer-owned credits''. Engines reported as 
``nonmanufacturer-owned credits'' shall comply with the FEL and the 
requirements of the ABT program in all other respects.
    (2) Only manufacturer-owned credits reported as ``ABT-only credits'' 
shall be used in the averaging, trading, and banking provisions 
described in this section.
    (3) Credits shall not be double-counted. Credits used in the ABT 
program may not be provided to an engine purchaser for use in another 
program.
    (4) Manufacturers shall determine and state the number of engines 
sold as ``ABT-only credits'' and ``nonmanufacturer-owned credits'' in 
the end-of-model year reports required under Sec.86.001-23.
    (k) Additional flexibility for diesel-cycle engines. If a diesel-
cycle engine family meets the conditions of either paragraph (k)(1) or 
(2) of this section, a Discount of 1.0 may be used in the trading and 
banking calculation, for both NOX plus NMHC and for 
particulate, described in paragraph (c)(1) of this section.
    (1) The engine family certifies with a certification level of 1.9 g/
bhp-hr NOX plus NMHC or lower for all diesel-cycle engine 
families.
    (2) All of the following must apply to the engine family:
    (i) Diesel-cycle engines only;
    (ii) 2004, 2005, and 2006 model years only;
    (iii) Must be an engine family using carry-over certification data 
from prior to model year 2004 where the NOX plus the HC 
certification level prior to model year 2004 is below the NOX 
plus NMHC or NOX plus NMHCE standard set forth in Sec.
86.004-11. Under this option, the NOX credits generated from 
this engine family prior to model year 2004 may be used as 
NOX plus NMHC credits.
    (l) Additional flexibility for Otto-cycle engines. If an Otto-cycle 
engine family meets the conditions of paragraph (l)(1) or (2) of this 
section, a discount of 1.0 may be used in the trading and banking 
credits calculation for NOX plus NMHC described in paragraph 
(c)(1) of this section, as follows:
    (1) The engine family has a FEL of 0.5 g/bhp-hr NOX plus 
NMHC or lower;
    (2) All of the following conditions are met:
    (i) For first three consecutive model years that the engine family 
is certified to a NOX plus NMHC standard contained in Sec.
86.005-10;
    (ii) The engine family is certified using carry-over data from an 
engine family which was used to generate early NOX credits 
per Sec.86.000-15(k) where the sum of the NOX FEL plus the 
HC (or hydrocarbon equivalent where applicable) certification level is 
below 1.0 g/bhp-hr.

Sec.86.004-16  Prohibition of defeat devices.

    (a) No new heavy-duty vehicle or heavy-duty engine shall be equipped 
with a defeat device.
    (b) The Administrator may test or require testing on any vehicle or 
engine at a designated location, using driving cycles and conditions 
which may reasonably be expected to be encountered in normal operation 
and use, for the purpose of investigating a potential defeat device.
    (c) [Reserved]
    (d) For vehicle and engine designs designated by the Administrator 
to be investigated for possible defeat devices:
    (1) General. The manufacturer must show to the satisfaction of the 
Administrator that the vehicle or engine design does not incorporate 
strategies

[[Page 456]]

that reduce emission control effectiveness exhibited during the 
applicable Federal emissions test procedures when the vehicle or engine 
is operated under conditions which may reasonably be expected to be 
encountered in normal operation and use, unless one of the specific 
exceptions set forth in the definition of ``defeat device'' in Sec.
86.004-2 has been met.
    (2) Information submissions required. The manufacturer will provide 
an explanation containing detailed information (including information 
which the Administrator may request to be submitted) regarding test 
programs, engineering evaluations, design specifications, calibrations, 
on-board computer algorithms, and design strategies incorporated for 
operation both during and outside of the applicable Federal emission 
test procedure.

(A) If the manufacturer elects to participate in the particulate 
averaging program for diesel light-duty vehicles and/or diesel light-
duty trucks or the particulate averaging program for heavy-duty diesel 
engines, the application must list the family particulate emission limit 
and the projected U.S. production volume of the family for the model 
year.
    (B) The manufacturer shall choose the level of the family 
particulate emission limits, accurate to hundredth of a gram per mile or 
hundredth of a gram per brake horsepowerhour for HDEs.
    (C) The manufacturer may at any time during production elect to 
change the level of any family particulate emission limit(s) by 
submitting the new limit(s) to the Administrator and by demonstrating 
compliance with the limit(s) as described in Sec. Sec.86.090-2 and 
86.094-28(b)(5)(i).
    (ii) NOX and NOX plus NMHC averaging. (A) If the manufacturer elects 
to participate in the NOX averaging program for light-duty 
trucks or otto-cycle HDEs or the NOX plus NMHC averaging 
program for diesel-cycle HDEs, the application must list the family 
emission limit and the projected U.S. production volume of the family 
for the model year.
    (B) The manufacturer shall choose the level of the family emission 
limits, accurate to one-tenth of a gram per mile or to one-tenth of a 
gram per brake horsepower-hour for HDEs.
    (C) The manufacturer may at any time during production elect to 
change the level of any family emission limit(s) by submitting the new 
limits to the Administrator and by demonstrating compliance with the 
limit(s) as described in Sec. Sec.86.088-2 and 86.094-28(b)(5)(ii).

Load Response Test conducted according to Sec.86.1380-2004, including, 
at a minimum, test results conducted at each of the speeds identified in 
Sec.86.1380-2004. Load Response Test data submissions are not 
necessary for carry-over engine families for which Load Response Test 
data has been previously submitted. In addition, upon approval of the 
Administrator, manufacturers may carry Load Response Test data across 
from one engine family to other engine families, provided that the 
carry-across engine families use similar emission control technology 
hardware which would be expected to result in the generation of similar 
emission data when run over the Load Response Test.
    (n) Upon request from EPA, a manufacturer must provide to EPA any 
hardware (including scan tools), passwords, and/or documentation 
necessary for EPA to read, interpret, and store (in engineering units if 
applicable) any information broadcast by an engine's on-board computers 
and electronic control modules which relates in any way to emission 
control devices and auxiliary emission control devices, provided that 
such hardware, passwords, or documentation exists and is not otherwise 
commercially available. Passwords include any information necessary to 
enable generic scan tools or personal computers access to proprietary 
emission related information broadcast by an engine's on-board computer, 
if such passwords exist. This requirement includes access by EPA to any 
proprietary code information which may be broadcast by an engine's on-
board computer and electronic control modules. Information which is 
confidential business information must be marked as such. Engineering 
units refers to the ability to read, interpret, and store information in 
commonly understood engineering units, for example, engine speed in 
revolutions per minute or per second, injection timing parameters such 
as start of injection in degree's before top-dead center, fueling rates 
in cubic centimeters per stroke, vehicle speed in miles per hour or 
kilometers per hour. This paragraph (n) does not restrict EPA authority 
to take any action authorized by section 208 of the Clean Air Act.

    (iii) The adjustment, cleaning, repair, or replacement of items 
listed in paragraphs (b)(4)(iii) (A)-(G) of this section shall occur at 
100,000 miles (or 3,000 hours) of use and at 100,000-mile (or 3,000-
hour) intervals thereafter for light heavy-duty diesel engines, or, at 
150,000 miles (or 4,500 hours) intervals thereafter for medium and heavy 
heavy-duty diesel engines.
    (A) Fuel injectors.
    (B) Turbocharger.
    (C) Electronic engine control unit and its associated sensors and 
actuators.
    (D) Particulate trap or trap oxidizer systems including related 
components (adjustment and cleaning only for filter element, replacement 
of the filter element is not allowed during the useful life).
    (E) Exhaust gas recirculation system (including all related control 
valves and tubing) except as otherwise provided in paragraph 
(b)(4)(i)(A) of this section.
    (F) Catalytic converter (adjustment and cleaning only for catalyst 
beds, replacement of the bed is not allowed during the useful life).
    (G) Any other add-on emissions-related component (i.e., a component 
whose sole or primary purpose is to reduce emissions or whose failure 
will significantly degrade emissions control and whose function is not 
integral to the design and performance of the engine.)
    (iv) [Reserved]
    (v) For engines that use selective catalytic reduction, the diesel 
exhaust fluid (DEF) tank must be sized so that DEF replenishment can 
occur at an interval, in miles or hours of vehicle operation, that is no 
less than the miles or hours of vehicle operation corresponding to the 
vehicle's fuel capacity. Use good engineering judgment to ensure that 
you meet this requirement for worst-case operation. For example, if the 
highest rate of DEF consumption (relative to fuel consumption) will 
occur under highway driving conditions (characterized by the SET), the 
DEF tank should be large enough that a single tankful of DEF would be 
enough to continue proper operation of the SCR system for the expected 
highway driving range with a single tank of fuel. Conversely, if the 
highest rate of DEF consumption (relative to fuel consumption) will 
occur under city or urban driving conditions (characterized by the 
transient FTP test), the DEF tank should be large enough that a single 
tank of DEF would be enough to continue proper operation of the SCR 
system for the expected city driving range with a single tank of fuel. 
For engine testing in a laboratory, any size DEF tank and fuel tank may 
be used; however, for our testing of engines, we may require you to 
provide us with a

[[Page 459]]

production-type DEF tank, including any associated sensors.
    (5) [Reserved]
    (6)(i) The following components are defined as critical emission-
related components:
    (A) Catalytic converter.
    (B) Air injection system components.
    (C) Electronic engine control unit and its associated sensors 
(including oxygen sensor if installed) and actuators.
    (D) Exhaust gas recirculation system (including all related filters, 
coolers, control valves, and tubing).
    (E) Crankcase ventilation valves and filters.
    (F) Evaporative and refueling emission control system components 
(excluding canister air filter).
    (G) Particulate trap or trap-oxidizer system.
    (H) Components comprising the selective catalytic reduction system 
(including DEF tank).
    (I) Any other component whose primary purpose is to reduce emissions 
or whose failure would commonly increase emissions of any regulated 
pollutant without significantly degrading engine performance.
    (ii) All critical emission-related scheduled maintenance must have a 
reasonable likelihood of being performed in-use. The manufacturer shall 
be required to show the reasonable likelihood of such maintenance being 
performed in-use, and such showing shall be made prior to the 
performance of the maintenance on the durability data engine. Critical 
emission-related scheduled maintenance items which satisfy one of the 
conditions defined in paragraphs (b)(6)(ii) (A)-(F) of this section will 
be accepted as having a reasonable likelihood of the maintenance item 
being performed in-use, except that DEF replenishment must satisfy 
paragraph (b)(6)(ii)(A) or (F) of this section to be accepted as having 
a reasonable likelihood of the maintenance item being performed in-use.
    (A) Data are presented which establish for the Administrator a 
connection between emissions and vehicle performance such that as 
emissions increase due to lack of maintenance, vehicle performance will 
simultaneously deteriorate to a point unacceptable for typical driving.
    (B) Survey data are submitted which adequately demonstrate to the 
Administrator that, at an 80 percent confidence level, 80 percent of 
such engines already have this critical maintenance item performed in-
use at the recommended interval(s).
    (C) A clearly displayed visible signal system approved by the 
Administrator is installed to alert the vehicle driver that maintenance 
is due. A signal bearing the message ``maintenance needed'' or ``check 
engine'', or a similar message approved by the Administrator, shall be 
actuated at the appropriate mileage point or by component failure. This 
signal must be continuous while the engine is in operation and not be 
easily eliminated without performance of the required maintenance. 
Resetting the signal shall be a required step in the maintenance 
operation. The method for resetting the signal system shall be approved 
by the Administrator. For HDEs, the system must not be designed to 
deactivate upon the end of the useful life of the engine or thereafter.
    (D) A manufacturer may desire to demonstrate through a survey that a 
critical maintenance item is likely to be performed without a visible 
signal on a maintenance item for which there is no prior in-use 
experience without the signal. To that end, the manufacturer may in a 
given model year market up to 200 randomly selected vehicles per 
critical emission-related maintenance item without such visible signals, 
and monitor the performance of the critical maintenance item by the 
owners to show compliance with paragraph (b)(6)(ii)(B) of this section. 
This option is restricted to two consecutive model years and may not be 
repeated until any previous survey has been completed. If the critical 
maintenance involves more than one engine family, the sample will be 
sales weighted to ensure that it is representative of all the families 
in question.
    (E) The manufacturer provides the maintenance free of charge, and 
clearly informs the customer that the maintenance is free in the 
instructions provided under Sec.86.087-38.
    (F) Any other method which the Administrator approves as 
establishing a

[[Page 460]]

reasonable likelihood that the critical maintenance will be performed 
in-use.
    (iii) Visible signal systems used under paragraph (b)(6)(ii)(C) of 
this section are considered an element of design of the emission control 
system. Therefore, disabling, resetting, or otherwise rendering such 
signals inoperative without also performing the indicated maintenance 
procedure is a prohibited act under section 203(a)(3) of the Clean Air 
Act (42 U.S.C. 7522(a)(3)).
    (b)(7)-(h) [Reserved]. For guidance see Sec.86.094-25.
    (i) Notwithstanding the provisions of paragraph (b)(4) and (6) of 
this section, manufacturers may schedule replacement or repair of 
particulate trap (or trap oxidizer) systems or catalytic converters 
(including NOX adsorbers), provided that the manufacturer 
demonstrates to the Administrator's satisfaction that the repair or 
replacement will be performed according to the schedule and the 
manufacturer pays for the repair or replacement.

Sec.86.004-26  Mileage and service accumulation; emission measurements.

    (a)-(b) [Reserved]
    (c)(1) Paragraph (c) of this section applies to heavy-duty engines.
    (2) Two types of service accumulation are applicable to heavy-duty 
engines, as described in paragraphs (c)(2)(i) and (ii) of this section. 
For Otto-cycle heavy-duty engines exhaust emissions, the service 
accumulation method used by a manufacturer must be designed to 
effectively predict the deterioration of emissions in actual use over 
the full useful life of the of the candidate in-use vehicles and must 
cover the breadth of the manufacturer's product line that will be 
covered by the durability procedure. Manufacturers not selecting Options 
1 or 2 described in Sec.86.005-10(f) may certify Otto-cycle engines 
using the provisions contained in Sec.86.094-26(c)(2) rather than 
those contained in this paragraph (c)(2) for 2004 model year engine 
families certified using carry-over durability data, except for those 
engines used for early credit banking as allowed in Sec.86.000-15(k).
    (i) Service accumulation on engines, subsystems, or components 
selected by the manufacturer under Sec.86.094-24(c)(3)(i). The 
manufacturer determines the form and extent of this service 
accumulation, consistent with good engineering practice, and describes 
it in the application for certification.
    (ii) Dynamometer service accumulation on emission data engines 
selected under Sec.86.094-24(b)(2) or (3). The manufacturer determines 
the engine operating schedule to be used for dynamometer service 
accumulation, consistent with good engineering practice. A single engine 
operating schedule shall be used for all engines in an engine family-
control system combination. Operating schedules may be different for 
different combinations.
    (3) Exhaust emission deterioration factors will be determined on the 
basis of the service accumulation described in Sec.86.000-26(b)(2)(i) 
and related testing, according to the manufacturer's procedures.
    (4) The manufacturer shall determine, for each engine family, the 
number of hours at which the engine system combination is stabilized for 
emission-data testing. The manufacturer shall maintain, and provide to 
the Administrator if requested, a record of the rationale used in making 
this determination. The manufacturer may elect to accumulate 125 hours 
on each test engine within an engine family without making a 
determination. Any engine used to represent emission-data engine 
selections under Sec.86.094-24(b)(2) shall be equipped with an engine 
system combination that has accumulated at least the number of hours 
determined under this paragraph. Complete exhaust emission tests shall 
be conducted for each emission-data engine selection under Sec.86.094-
24(b)(2). Evaporative emission controls must be connected, as described 
in 40 CFR part 1065, subpart F. The Administrator may determine under 
Sec.86.094-24(f) that no testing is required.
    (d)(1) This paragraph (d) applies for heavy-duty engines.
    (2)(i) The results of all emission testing shall be supplied to the 
Administrator. The manufacturer shall furnish to the Administrator 
explanation for voiding any test. The Administrator

[[Page 461]]

will determine if voiding the test was appropriate based upon the 
explanation given by the manufacturer for the voided test. Tests between 
test points may be conducted as required by the Administrator. Data from 
all tests (including voided tests) may be submitted weekly to the 
Administrator, but shall be delivered to the Administrator within 7 days 
after completion of the test. In addition, all test data shall be 
compiled and provided to the Administrator in accordance with Sec.
86.007-23. Where the Administrator conducts a test on a durability data 
vehicle at a prescribed test point, the results of that test will be 
used in the calculation of the deterioration factor.
    (ii) The results of all emission tests shall be recorded and 
reported to the Administrator. These test results shall be rounded as 
specified in 40 CFR part 1065 to the number of decimal places contained 
in the applicable emission standard expressed to one additional 
significant figure.
    (3) Whenever a manufacturer intends to operate and test a vehicle 
(or engine) that may be used for emission data, the manufacturer shall 
retain in its records all information concerning all emission tests and 
maintenance, including vehicle (or engine) alterations to represent 
other vehicle (or engine) selections. This information shall be 
submitted, including the vehicle (or engine) description and 
specification information required by the Administrator, to the 
Administrator following the emission test.
    (4) Emission testing of any type with respect to any certification 
vehicle or engine other than that specified in this subpart is not 
allowed except as such testing may be specifically authorized by the 
Administrator.

Sec.86.004-28  Compliance with emission standards.

    (a)-(b) [Reserved]
    (c)(1) Paragraph (c) of this section applies to heavy-duty engines.
    (2) The applicable exhaust emission standards (or family emission 
limits, as appropriate) for Otto-cycle engines and for diesel-cycle 
engines apply to the emissions of engines for their useful life.
    (3) Since emission control efficiency generally decreases with the 
accumulation of service on the engine, deterioration factors will be 
used in combination with emission data engine test results as the basis 
for determining compliance with the standards.
    (4)(i) Paragraph (c)(4) of this section describes the procedure for 
determining compliance of an engine with emission standards (or family 
emission limits, as appropriate), based on deterioration factors 
supplied by the manufacturer. Deterioration factors shall be established 
using applicable emissions test procedures. NOX plus NMHC 
deterioration factors shall be established based on the sum of the 
pollutants. When establishing deterioration factors for NOX 
plus NMHC, a negative deterioration (emissions decrease from the 
official exhaust emissions test result) for one pollutant may not offset 
deterioration of the other pollutant. Where negative deterioration 
occurs for NOX and/or NMHC, the official exhaust emission 
test result shall be used for purposes of determining the NOX 
plus NMHC deterioration factor.
    (ii) Separate exhaust emission deterioration factors, determined 
from tests of engines, subsystems, or components conducted by the 
manufacturer, shall be supplied for each engine-system combination. For 
Otto-cycle engines, separate factors shall be established for transient 
NMHC (NMHCE), CO, NOX. NOX plus NMHC, and idle CO, 
for those engines utilizing aftertreatment technology (e.g., catalytic 
converters). For diesel-cycle engines, separate factors shall be 
established for transient NMHC (NMHCE), CO, NOX. 
NOX plus NMHC and exhaust particulate. For diesel-cycle smoke 
testing, separate factors shall also be established for the acceleration 
mode (designated as ``A''), the lugging mode (designated as ``B''), and 
peak opacity (designated as ``C'').
    (iii)(A) Paragraphs (c)(4)(iii)(A) (1) and (2) of this section apply 
to Otto-cycle HDEs.
    (1) Otto-cycle HDEs not utilizing aftertreatment technology (e.g., 
catalytic converters). For transient NMHC (NMHCE), CO, NOX. 
the official exhaust

[[Page 462]]

emission results for each emission data engine at the selected test 
point shall be adjusted by the addition of the appropriate deterioration 
factor. However, if the deterioration factor supplied by the 
manufacturer is less than zero, it shall be zero for the purposes of 
this paragraph.
    (2) Otto-cycle HDEs utilizing aftertreatment technology (e.g., 
catalytic converters). For transient NMHC (NMHCE), CO, NOX. 
and for idle CO, the official exhaust emission results for each emission 
data engine at the selected test point shall be adjusted by 
multiplication by the appropriate deterioration factor, except as 
otherwise provided in paragraph (c)(4)(iii)(A)(3) of this section. The 
deterioration factor must be calculated by dividing the exhaust 
emissions at full useful life by the stabilized mileage emission level 
(reference Sec.86.096-26(c)(4), e.g., 125 hours). However, if the 
deterioration factor supplied by the manufacturer is less than one, it 
shall be one for purposes of this paragraph (c)(4)(iii)(A)(2).
    (3) An Otto-cycle heavy-duty engine manufacturer who believes that a 
deterioration factor derived using the calculation methodology described 
in paragraph (c)(4)(iii)(4)(A)(2) of this section are significantly 
unrepresentative for one or more engine families (either too high or too 
low) may petition the Administrator to allow for the use of an additive 
rather than a multiplicative deterioration factor. This petition must 
include full rationale behind the request together with any supporting 
data or other evidence. Based on this or other information the 
Administration may allow for an alternative procedure. Any petition 
should be submitted in a timely manner, to allow adequate time for a 
thorough evaluation. Manufacturers using an additive deterioration 
factor under this paragraph (c)(4)(iii)(A)(3) must perform in-use 
verification testing to determine if the additive deterioration factor 
reasonably predicts actual in-use emissions. The plan for the in-use 
verification testing must be approved by the Administrator as part of 
the approval process described in this paragraph (c)(4)(iii)(4)(A)(3) 
prior to the use of the additive deterioration factor. The Administrator 
may consider the results of the in-use verification testing both in 
certification and in-use compliance programs.
    (B) Paragraph (c)(4)(iii)(B) of this section applies to diesel-cycle 
HDEs.
    (1) Additive deterioration factor for exhaust emissions. Except as 
specified in paragraph (c)(4)(iii)(B)(2) of this section, use an 
additive deterioration factor for exhaust emissions. An additive 
deterioration factor for a pollutant is the difference between exhaust 
emissions at the end of the useful life and exhaust emissions at the 
low-hour test point. In these cases, adjust the official emission 
results for each tested engine at the selected test point by adding the 
factor to the measured emissions. If the factor is less than zero, use 
zero. Additive deterioration factors must be specified to one more 
decimal place than the applicable standard.
    (2) Multiplicative deterioration factor for exhaust emissions. Use a 
multiplicative deterioration factor if good engineering judgment calls 
for the deterioration factor for a pollutant to be the ratio of exhaust 
emissions at the end of the useful life to exhaust emissions at the low-
hour test point. For example, if you use aftertreatment technology that 
controls emissions of a pollutant proportionally to engine-out 
emissions, it is often appropriate to use a multiplicative deterioration 
factor. Adjust the official emission results for each tested engine at 
the selected test point by multiplying the measured emissions by the 
deterioration factor. If the factor is less than one, use one. A 
multiplicative deterioration factor may not be appropriate in cases 
where testing variability is significantly greater than engine-to-engine 
variability. Multiplicative deterioration factors must be specified to 
one more significant figure than the applicable standard.
    (3) Diesel-cycle HDEs only. For acceleration smoke (``A''), lugging 
smoke (``B''), and peak smoke (``C''), the official exhaust emission 
results for each emission data engine at the selected test point shall 
be adjusted by the addition of the appropriate deterioration factor. 
However, if the deterioration factor supplied by the manufacturer is 
less than zero, it shall be zero for the purposes of this paragraph.

[[Page 463]]

    (4) The emission values to compare with the standards (or family 
emission limits, as appropriate) shall be the adjusted emission values 
of paragraph (c)(4)(iii) of this section, rounded to the same number of 
significant figures as contained in the applicable standard in 
accordance with ASTM E 29-93a (as referenced in Sec.86.094-28 
(a)(4)(i)(B)(2)(ii)), for each emission data engine.
    (5) and (6) [Reserved]
    (7) Every test engine of an engine family must comply with all 
applicable standards (or family emission limits, as appropriate), as 
determined in paragraph (c)(4)(iv) of this section, before any engine in 
that family will be certified.
    (8) For the purposes of setting an NMHC plus NOX 
certification level or FEL for a diesel-fueled engine family, the 
manufacturer may use one of the following options for the determination 
of NMHC for an engine family. The manufacturer must declare which option 
is used in its application for certification of that engine family.
    (i) THC may be used in lieu of NMHC for the standards set forth in 
Sec.86.004-11.
    (ii) The manufacturer may choose its own method to analyze methane 
with prior approval of the Administrator.
    (iii) The manufacturer may assume that two percent of the measured 
THC is methane (NMHC = 0.98 x THC).
    (d)(1) Paragraph (d) of this section applies to heavy-duty vehicles 
equipped with gasoline-fueled or methanol-fueled engines.
    (2) The applicable evaporative emission standards in this subpart 
apply to the emissions of vehicles for their useful life.
    (3)(i) For vehicles with a GVWR of up to 26,000 pounds, because it 
is expected that emission control efficiency will change during the 
useful life of the vehicle, an evaporative emission deterioration factor 
shall be determined from the testing described in Sec.86.098-23(b)(3) 
for each evaporative emission family-evaporative emission control system 
combination to indicate the evaporative emission control system 
deterioration during the useful life of the vehicle (minimum 50,000 
miles). The factor shall be established to a minimum of two places to 
the right of the decimal.
    (ii) For vehicles with a GVWR of greater than 26,000 pounds, because 
it is expected that emission control efficiency will change during the 
useful life of the vehicle, each manufacturer's statement as required in 
Sec.86.098-23(b)(4)(ii) shall include, in accordance with good 
engineering practice, consideration of control system deterioration.
    (4) The evaporative emission test results, if any, shall be adjusted 
by the addition of the appropriate deterioration factor, provided that 
if the deterioration factor as computed in paragraph (d)(3) of this 
section is less than zero, that deterioration factor shall be zero for 
the purposes of this paragraph.
    (5) The emission level to compare with the standard shall be the 
adjusted emission level of paragraph (d)(4) of this section. Before any 
emission value is compared with the standard, it shall be rounded, in 
accordance with ASTM E 29-93a (as referenced in Sec.86.094-28 
(a)(4)(i)(B)(2)(ii)), to two significant figures. The rounded emission 
values may not exceed the standard.
    (6) Every test vehicle of an evaporative emission family must comply 
with the evaporative emission standard, as determined in paragraph 
(d)(5) of this section, before any vehicle in that family may be 
certified.
    (e) [Reserved]
    (f)-(g) [Reserved]
    (h) [Reserved]. For guidance see Sec.86.001-28.
    (i) This paragraph (i) describes how to adjust emission results from 
model year 2020 and earlier heavy-duty engines equipped with exhaust 
aftertreatment to account for regeneration events. This provision only 
applies for engines equipped with emission controls that are regenerated 
on an infrequent basis. For the purpose of this paragraph (i), the term 
``regeneration'' means an event during which emission levels change 
while the aftertreatment performance is being restored by design. 
Examples of regenerations are increasing exhaust gas temperature to 
remove sulfur from an adsorber or increasing exhaust gas temperature to 
oxidize PM in a trap. For the purpose of this paragraph (i), the term 
``infrequent'' means having an expected frequency of less than once

[[Page 464]]

per transient test cycle. Calculation and use of adjustment factors are 
described in paragraphs (i)(1) through (5) of this section. If your 
engine family includes engines with one or more AECDs for emergency 
vehicle applications approved under paragraph (4) of the definition of 
defeat device in Sec.86.004-2, do not consider additional 
regenerations resulting from those AECDs when calculating emission 
factors or frequencies under this paragraph (i).
    (1) Development of adjustment factors. Manufacturers must develop 
separate pairs of adjustment factors (an upward adjustment factor and a 
downward adjustment factor) for each pollutant based on measured 
emission data and observed regeneration frequency. Adjustment factors 
may be carried-over to subsequent model years or carried-across to other 
engine families only where the Administrator determines that such carry-
over or carry-across is consistent with good engineering judgment. 
Adjustment factors should generally apply to an entire engine family, 
but manufacturers may develop separate adjustment factors for different 
engine configurations within an engine family. All adjustment factors 
for regeneration are additive.
    (2) Calculation of adjustment factors. The adjustment factors are 
calculated from the following parameters: the measured emissions from a 
test in which the regeneration occurs (EFH), the measured 
emissions from a test in which the regeneration does not occur 
(EFL), and the frequency of the regeneration event in terms 
of fraction of tests during which the regeneration occurs (F). The 
average emission rate (EFA) is calculated as:

EFA = (F)(EFH) + (1 - F)(EFL)

    (i) The upward adjustment factor (UAF) is calculated as: UAF = 
EFA - EFL.
    (ii) The downward adjustment factor (DAF) is calculated as: DAF = 
EFA - EFH.
    (3) Use of adjustment factors. Upward adjustment factors are added 
to measured emission rates for all tests in which the regeneration does 
not occur. Downward adjustment factors are added to measured emission 
rates for all tests in which the regeneration occurs. The occurrence of 
the regeneration must be identified in a manner that is readily apparent 
during all testing. Where no regeneration is identified, the upward 
adjustment factor shall be applied.
    (4) Sample calculation. If EFL is 0.10 g/bhp-hr, 
EFH is 0.50 g/bhp-hr, and F is 0.1 (i.e., the regeneration 
occurs once for each ten tests), then:

EFA = (0.1)(0.5 g/bhp-hr) + (1.0 - 0.1)(0.1 g/bhp-hr) = 0.14 
g/bhp-hr
UAF = 0.14 g/bhp-hr - 0.10 g/bhp-hr = 0.04 g/bhp-hr
DAF = 0.14 g/bhp-hr - 0.50 g/bhp-hr = -0.36 g/bhp-hr

    (5) Options. (i) A manufacturer may elect to omit adjustment factors 
for one or more of its engine families (or configurations) because the 
effect of the regeneration is small, or because it is not practical to 
identify when regenerations occur. In these cases, no upward or downward 
adjustment factor shall be added, and the manufacturer is liable for 
compliance with the emission standards for all tests, without regard to 
whether a regeneration occurs.
    (ii) Upon request by the manufacturer, the Administrator may account 
for regeneration events differently than is provided in this paragraph 
(i). However, this option only applies for events that occur extremely 
infrequently, and which cannot be practically addressed using the 
adjustment factors described in this paragraph (i).
    (j) For model year 2021 and later engines using aftertreatment 
technology with infrequent regeneration events that may occur during 
testing, take one of the following approaches to account for the 
emission impact of regeneration:
    (1) You may use the calculation methodology described in 40 CFR 
1065.680 to adjust measured emission results. Do this by developing an 
upward adjustment factor and a downward adjustment factor for each 
pollutant based on measured emission data and observed regeneration 
frequency as follows:
    (i) Adjustment factors should generally apply to an entire engine 
family,

[[Page 465]]

but you may develop separate adjustment factors for different 
configurations within an engine family. Use the adjustment factors from 
this section for all testing for the engine family.
    (ii) You may use carryover or carry-across data to establish 
adjustment factors for an engine family as described in Sec.86.001-
24(f), consistent with good engineering judgment.
    (iii) Identify the value of F in each application for the 
certification for which it applies.
    (2) You may ask us to approve an alternate methodology to account 
for regeneration events. We will generally limit approval to cases where 
your engines use aftertreatment technology with extremely infrequent 
regeneration and you are unable to apply the provisions of this section.
    (3) You may choose to make no adjustments to measured emission 
results if you determine that regeneration does not significantly affect 
emission levels for an engine family (or configuration) or if it is not 
practical to identify when regeneration occurs. If you choose not to 
make adjustments under paragraph (j)(1) or (2) of this section, your 
engines must meet emission standards for all testing, without regard to 
regeneration.

Sec.86.004-38  Maintenance instructions.

    (a) The manufacturer shall furnish or cause to be furnished to the 
purchaser of each new motor vehicle (or motor vehicle engine) subject to 
the standards prescribed in Sec.86.099-8, Sec.86.004-9, Sec.
86.004-10, or Sec.86.004-11, as applicable, written instructions for 
the proper maintenance and use of the vehicle (or engine), by the 
purchaser consistent with the provisions of Sec.86.004-25, which 
establishes what scheduled maintenance the Administrator approves as 
being reasonable and necessary.
    (1) The maintenance instructions required by this section shall be 
in clear, and to the extent practicable, nontechnical language.
    (2) The maintenance instructions required by this section shall 
contain a general description of the documentation which the 
manufacturer will require from the ultimate purchaser or any subsequent 
purchaser as evidence of compliance with the instructions.
    (b) Instructions provided to purchasers under paragraph (a) of this 
section shall specify the performance of all scheduled maintenance 
performed by the manufacturer on certification durability vehicles and, 
in cases where the manufacturer performs less maintenance on

recommended maintenance in order to maintain the emissions defect and 
emissions performance warranty or manufacturer recall liability.

[[Page 466]]

    (e) The manufacturer may choose to include in such instructions an 
explanation of any distinction between the useful life specified on the 
label, and the emissions defect and emissions performance warranty 
period. The explanation must clearly state that the useful life period 
specified on the label represents the average period of use up to 
retirement or rebuild for the engine family represented by the engine 
used in the vehicle. An explanation of how the actual useful lives of 
engines used in various applications are expected to differ from the 
average useful life may be included. The explanation(s) shall be in 
clear, non-technical language that is understandable to the ultimate 
purchaser.
    (f) If approved by the Administrator, the instructions provided to 
purchasers under paragraph (a) of this section shall indicate what 
adjustments or modifications, if any, are necessary to allow the vehicle 
to meet applicable emission standards at elevations above 4,000 feet, or 
at elevations of 4,000 feet or less.
    (g) [Reserved]
    (h) The manufacturer shall furnish or cause to be furnished to the 
purchaser of each new motor engine subject to the standards prescribed 
in Sec.86.004-10 or Sec.86.004-11, as applicable, the following:

Sec.86.004-40  Heavy-duty engine rebuilding practices.

    The provisions of this section are applicable to heavy-duty engines 
subject to model year 2004 or later standards and are applicable to the 
process of engine rebuilding (or rebuilding a portion of an engine or 
engine system). The process of engine rebuilding generally includes 
disassembly, replacement of multiple parts due to wear, and reassembly, 
and also may include the removal of the engine from the vehicle and 
other acts associated with rebuilding an engine. Any deviation from the 
provisions contained in this section is a prohibited act under section 
203(a)(3) of the Clean Air Act (42 U.S.C. 7522(a)(3)).
    (a) When rebuilding an engine, portions of an engine, or an engine 
system, there must be a reasonable technical basis for knowing that the 
resultant engine is equivalent, from an emissions standpoint, to a 
certified configuration (i.e., tolerances, calibrations, specifications) 
and the model year(s) of the resulting engine configuration must be 
identified. A reasonable basis would exist if:
    (1) Parts installed, whether the parts are new, used, or rebuilt, 
are such that a person familiar with the design and function of motor 
vehicle engines would reasonably believe that the parts perform the same 
function with respect to emissions control as the original parts; and
    (2) Any parameter adjustment or design element change is made only:
    (i) In accordance with the original engine manufacturer's 
instructions; or
    (ii) Where data or other reasonable technical basis exists that such 
parameter adjustment or design element change, when performed on the 
engine or similar engines, is not expected to adversely affect in-use 
emissions.
    (b) When an engine is being rebuilt and remains installed or is 
reinstalled in the same vehicle, it must be rebuilt to a configuration 
of the same or later model year as the original engine.

[[Page 467]]

When an engine is being replaced, the replacement engine must be an 
engine of (or rebuilt to) a configuration of the same or later model 
year as the original engine.
    (c) At time of rebuild, emissions-related codes or signals from on-
board monitoring systems may not be erased or reset without diagnosing 
and responding appropriately to the diagnostic codes, regardless of 
whether the systems are installed to satisfy requirements in Sec.
86.004-25 or for other reasons and regardless of form or interface. 
Diagnostic systems must be free of all such codes when the rebuilt 
engine is returned to service. Such signals may not be rendered 
inoperative during the rebuilding process.
    (d) When conducting a rebuild without removing the engine from the 
vehicle, or during the installation of a rebuilt engine, all critical 
emissions-related components listed in Sec.86.004-25(b) not otherwise 
addressed by paragraphs (a) through (c) of this section must be checked 
and cleaned, adjusted, repaired, or replaced as necessary, following 
manufacturer recommended practices.
    (e) Records shall be kept by parties conducting activities included 
in paragraphs (a) through (d) of this section. The records shall include 
at minimum the mileage and/or hours at time of rebuild, a listing of 
work performed on the engine and emissions-related control components 
including a listing of parts and components used, engine parameter 
adjustments, emissions-related codes or signals responded to and reset, 
and work performed under paragraph (d) of this section.
    (1) Parties may keep records in whatever format or system they 
choose as long as the records are understandable to an EPA enforcement 
officer or can be otherwise provided to an EPA enforcement officer in an 
understandable format when requested.
    (2) Parties are not required to keep records of information that is 
not reasonably available through normal business practices including 
information on activities not conducted by themselves or information 
that they cannot reasonably access.
    (3) Parties may keep records of their rebuilding practices for an 
engine family rather than on each individual engine rebuilt in cases 
where those rebuild practices are followed routinely.
    (4) Records must be kept for a minimum of two years after the engine 
is rebuilt.

    (ii) For engines not having a NOX FEL less than1.5 g/bhp-
hr, gaseous exhaust emissions shall not exceed the steady-state 
interpolated values determined by the Maximum Allowable Emission Limits 
(for the corresponding speed and load), as determined under Sec.
86.1360-2007(f), when the engine is operated in the steady-state control 
area defined under Sec.86.1360-2007(d).
    (4) NTE (i)(A) The brake-specific exhaust NMHC or NOX 
emissions in g/bhp-hr, as determined under Sec.86.1370-2007 pertaining 
to the not-to-exceed test procedures, shall not exceed 1.5 times the 
applicable NMHC or NOX emission standards or FELs specified 
in paragraph (a)(1) of this section, during engine and vehicle operation 
specified in paragraph (a)(4)(ii) of this section except as noted in 
paragraph (a)(4)(iii) of this section.
    (B) For engines not having a NOX FEL less than1.50 g/bhp-
hr, the brake-specific NOX and NMHC exhaust emissions in g/
bhp-hr, as determined under Sec.86.1370-2007 pertaining to the not-to-
exceed test procedures, shall not exceed 1.25 times the applicable 
emission standards or FELs specified in paragraph (a)(1) of this section 
(or of Sec.86.004-11, as allowed by paragraph (g) of this section), 
during engine and vehicle operation specified in paragraph (a)(4)(ii) of 
this section except as noted in paragraph (a)(4)(iii) of this section.
    (C) The brake-specific exhaust PM emissions in g/bhp-hr, as 
determined under Sec.86.1370-2007 pertaining to the not-to-exceed test 
procedures, shall not exceed 1.5 times the applicable PM emission 
standards or FEL (for FELs above the standard only) specified in 
paragraph (a)(1) of this section, during engine and vehicle operation 
specified in paragraph (a)(4)(ii) of this section except as noted in 
paragraph (a)(4)(iii) of this section.
    (D) The brake-specific exhaust CO emissions in g/bhp-hr, as 
determined under Sec.86.1370-2007 pertaining to the not-to-exceed test 
procedures, shall not exceed 1.25 times the applicable CO emission 
standards or FEL specified in paragraph (a)(1) of this section, during 
engine and vehicle operation specified in paragraph (a)(4)(ii) of this 
section except as noted in paragraph (a)(4)(iii) of this section.
    (ii) For each engine family, the not-to-exceed emission limits must 
apply during one of the following two ambient operating regions:
    (A) The not-to-exceed limits apply for all altitudes less than or 
equal to 5,500 feet above sea-level, during all ambient conditions 
(temperature and humidity). Temperature and humidity ranges for which 
correction factors are allowed are specified in Sec.86.1370-2007(e); 
or
    (B)(1) The not-to-exceed emission limits apply at all altitudes less 
than or equal to 5,500 feet above sea-level, for temperatures less than 
or equal to the temperature determined by the following equation at the 
specified altitude:

T = -0.00254 x A + 100

Where:

T = ambient air temperature in degrees Fahrenheit.
A = altitude in feet above sea-level (A is negative for altitudes below 
          sea-level).

    (2) Temperature and humidity ranges for which correction factors are 
allowed are specified in Sec.86.1370-2007(e);
    (iii) For engines equipped with exhaust gas recirculation, the not-
to-exceed emission limits specified in paragraph (a)(4)(i) of this 
section do not apply to engine or vehicle operation during cold 
operating conditions as specified in Sec.86.1370-2007(f).
    (iv) Deficiencies for NTE emission standards. (A) For model years 
2007 through 2009, upon application by the manufacturer, the 
Administrator may accept a HDDE as compliant with the NTE standards even 
though specific requirements are not fully met. Such compliances without 
meeting specific requirements, or deficiencies, will be granted only if 
compliance would be infeasible or unreasonable considering such factors 
as, but not limited to: Technical feasibility of the given hardware and 
lead time and production cycles including phase-in or phase-out of

[[Page 473]]

engines or vehicle designs and programmed upgrades of computers. 
Deficiencies will be approved on an engine model and/or horsepower 
rating basis within an engine family, and each approval is applicable 
for a single model year. A manufacturer's application must include a 
description of the auxiliary emission control device(s) which will be 
used to maintain emissions to the lowest practical level, considering 
the deficiency being requested, if applicable. An application for a 
deficiency must be made during the certification process; no deficiency 
will be granted to retroactively cover engines already certified.
    (B) Unmet requirements should not be carried over from the previous 
model year except where unreasonable hardware or software modifications 
would be necessary to correct the deficiency, and the manufacturer has 
demonstrated an acceptable level of effort toward compliance as 
determined by the Administrator. The NTE deficiency should only be seen 
as an allowance for minor deviations from the NTE requirements. The NTE 
deficiency provisions allow a manufacturer to apply for relief from the 
NTE emission requirements under limited conditions. EPA expects that 
manufacturers should have the necessary functioning emission control 
hardware in place to comply with the NTE.
    (C) For model years 2010 through 2013, the Administrator may allow 
up to three deficiencies per engine family. The provisions of paragraphs 
(a)(4)(iv)(A) and (B) of this section apply for deficiencies allowed by 
this paragraph (a)(4)(iv)(C). In determining whether to allow the 
additional deficiencies, the Administrator may consider any relevant 
factors, including the factors identified in paragraph (a)(4)(iv)(A) of 
this section. If additional deficiencies are approved, the Administrator 
may set any additional conditions that he/she determines to be 
appropriate.
    (v) The emission limits specified in paragraphs (a)(3) and (a)(4) of 
this section shall be rounded to the same number of significant figures 
as the applicable standards in paragraph (a)(1) of this section using 
ASTM E29-93a (Incorporated by reference at Sec.86.1).
    (vi) Manufacturers are not required to provide engine information 
exclusively related to in-use testing as part of initial certification. 
However, upon request from EPA the manufacturers must provide the 
information which clearly identifies parameters defining all NTE 
deficiencies described under paragraph (a)(4)(iv) of this section and 
parameters defining all NTE limited testing regions described under 
Sec.86.1370-2007(b)(6) and (7) that are requested. When requested, 
deficiencies and limited testing regions must be reported for all engine 
families and power ratings in English with sufficient detail for us to 
determine if a particular deficiency or limited testing region will be 
encountered in the emission test data from the portable emission-
sampling equipment and field-testing procedures referenced in Sec.
86.1375. Such information is to be provided within 60 days of the 
request from EPA.
    (b)(1) introductory text through (b)(1)(iii) [Reserved]. For 
guidance see Sec.86.004-11.
    (b)(1)(iv) Operation within the NTE zone (defined in Sec.86.1370-
2007) must comply with a filter smoke number of 1.0 under steady-state 
operation, or the following alternate opacity limits:
    (A) A 30 second transient test average opacity limit of 4% for a 5 
inch path; and
    (B) A 10 second steady state test average opacity limit of 4% for a 
5 inch path.
    (2)(i) The standards set forth in Sec.86.004-11 (b)(1)(i)-(iii) 
refer to exhaust smoke emissions generated under the conditions set 
forth in subpart I of this part and measured and calculated in 
accordance with those procedures.
    (ii) The standards set forth in paragraph (b)(1)(iv) of this section 
refer to exhaust smoke emissions generated under the conditions set 
forth in Sec.86.1370-2007 and calculated in accordance with the 
procedures set forth in Sec.86.1372-2007.
    (b)(3) and (b)(4) [Reserved]. For guidance see Sec.86.004-11.
    (c) No crankcase emissions shall be discharged directly into the 
ambient atmosphere from any new 2007 or later model year diesel HDE, 
with the following exception: HDEs equipped with

[[Page 474]]

turbochargers, pumps, blowers, or superchargers for air induction may 
discharge crankcase emissions to the ambient atmosphere if the emissions 
are added to the exhaust emissions (either physically or mathematically) 
during all emission testing. Manufacturers taking advantage of this 
exception must manufacture the engines so that all crankcase emission 
can be routed into a dilution tunnel (or other sampling system approved 
in advance by the Administrator), and must account for deterioration in 
crankcase emissions when determining exhaust deterioration factors. For 
the purpose of this paragraph (c), crankcase emissions that are routed 
to the exhaust upstream of exhaust aftertreatment during all operation 
are not considered to be ``discharged directly into the ambient 
atmosphere.''
    (d) Every manufacturer of new motor vehicle engines subject to the 
standards prescribed in this section shall, prior to taking any of the 
actions specified in section 203(a)(1) of the Act, test or cause to be 
tested motor vehicle engines in accordance with applicable procedures in 
subpart I or N of this part to ascertain that such test engines meet the 
requirements of paragraphs (a), (b), (c), and (d) of this section.
    (e) [Reserved]. For guidance see Sec.86.004-11.
    (f) (1) Model year 2007 and later diesel-fueled heavy-duty engines 
and vehicles for sale in Guam, American Samoa, or the Commonwealth of 
the Northern Mariana Islands shall be subject to the same standards and 
requirements as apply to 2006 model year diesel heavy-duty engines and 
vehicles, but only if the vehicle or engine bears a permanently affixed 
label stating:

    THIS ENGINE (or VEHICLE, as applicable) CONFORMS TO US EPA EMISSION 
STANDARDS APPLICABLE TO MODEL YEAR 2006. THIS ENGINE (or VEHICLE, as 
applicable) DOES NOT CONFORM TO US EPA EMISSION REQUIREMENTS IN EFFECT 
AT TIME OF PRODUCTION AND MAY NOT BE IMPORTED INTO THE UNITED STATES OR 
ANY TERRITORY OF THE UNITED STATES EXCEPT GUAM, AMERICAN SAMOA, OR THE 
COMMONWEALTH OF THE NORTHERN MARIANA ISLANDS.

    (2) The importation or sale of such a vehicle or engine for use at 
any location U.S. other than Guam, American Samoa, or the Commonwealth 
of the Northern Mariana Islands shall be considered a violation of 
section 203(a)(1) of the Clean Air Act. In addition, vehicles or vehicle 
engines subject to this exemption may not subsequently be imported or 
sold into any state or territory of the United States other than Guam, 
American Samoa, or Commonwealth of the Northern Mariana Islands.
    (g) Model year 2018 and later engines at or above 56 kW that will be 
installed in specialty vehicles as allowed by 40 CFR 1037.605 may meet 
alternate emission standards as follows:
    (1) The engines must be of a configuration that is identical to one 
that is certified under 40 CFR part 1039, and meet the following 
additional standards using the same duty cycles that apply under 40 CFR 
part 1039:
    (i) The engines must be certified with a Family Emission Limit for 
PM of 0.020 g/kW-hr.
    (ii) Diesel-fueled engines using selective catalytic reduction must 
meet an emission standard of 0.1 g/kW-hr for N2O.
    (2) Except as specified in this paragraph (g), engines certified 
under this paragraph (g) must meet all the requirements that apply under 
40 CFR part 1039 instead of the comparable provisions in this subpart A. 
Before shipping engines under this section, you must have written 
assurance from the vehicle manufacturers that they need a certain number 
of exempted engines under this section. In your annual production report 
under 40 CFR 1039.250, count these engines separately and identify the 
vehicle manufacturers that will be installing them. Treat these engines 
as part of the corresponding engine family under 40 CFR part 1039 for 
compliance purposes such as selective enforcement audits, in-use 
testing, defect reporting, and recall.
    (3) The engines must be labeled as described in Sec.86.095-35, 
with the following statement instead of the one specified in Sec.
86.095-35(a)(3)(iii)(H): ``This engine conforms to alternate standards 
for specialty vehicles under 40 CFR 86.007-11(g)''. Engines certified 
under this paragraph (g) may not have the label specified for nonroad 
engines in 40 CFR

[[Page 475]]

part 1039 or any other label identifying them as nonroad engines.
    (4) In a separate application for a certificate of conformity, 
identify the corresponding nonroad engine family, describe the label 
required under this paragraph (g), state that you meet applicable 
diagnostic requirements under 40 CFR part 1039, and identify your 
projected U.S.-directed production volume.
    (5) No additional certification fee applies for engines certified 
under this paragraph (g).
    (6) Engines certified under this paragraph (g) may not generate or 
use emission credits under this part or under 40 CFR part 1039. The 
vehicles in which these engines are installed may generate or use 
emission credits as described in 40 CFR part 1037.
    (7) Engines may instead meet standards for heavy-duty highway 
engines in California, as demonstrated by an Executive Order issued by 
the California Air Resources Board.
    (h)(1) For model years prior to 2012, for purposes of determining 
compliance after title or custody has transferred to the ultimate 
purchaser, for engines having a NOX FEL no higher than 1.30 
g/bhp-hr, the applicable compliance limit shall be determined by adding 
the applicable adjustment from paragraph (h)(2) of this section to the 
otherwise applicable standard or FEL for NOX.
    (2)(i) For engines with 110,000 or fewer miles, the adjustment is 
0.10 g/bhp-hr.
    (ii) For engines with 110,001 to 185,000 miles, the adjustment is 
0.15 g/bhp-hr.
    (iii) For engines with 185,001 or more miles, the adjustment is 0.20 
g/bhp-hr.
    (3) For model years prior to 2012, for purposes of determining 
compliance after title or custody has transferred to the ultimate 
purchaser, the applicable compliance limit shall be determined by adding 
0.01 g/bhp-hr to the otherwise applicable standard or FEL for PM.
    (i) [Reserved]
    (j) Engines installed in new glider vehicles are subject to the 
standards of this section as specified in 40 CFR part 1037.

Sec.86.007-15  NOX and particulate averaging, trading, and banking 
for heavy-duty engines.

    Section 86.007-15 includes text that specifies requirements that 
differ from Sec.86.004-15. Where a paragraph in Sec.86.004-15 is 
identical and applicable to Sec.86.007-15, this may be indicated by 
specifying the corresponding paragraph and the statement ``[Reserved]. 
For guidance see Sec.86.004-15.''
    (a)-(l) [Reserved]. For guidance see Sec.86.004-15.
    (m) The following provisions apply for model year 2007 and later 
engines (including engines certified during years 2007-2009 under the 
phase-in provisions of Sec.86.007-11(g)(1), Sec.86.005-10(a), or 
Sec.86.008-10(f)(1)). These provisions apply instead of the provisions 
of paragraphs Sec.86.004-15 (a) through (k) to the extent that they 
are in conflict.
    (1) Manufacturers of Otto-cycle engines may participate in an NMHC 
averaging, banking and trading program to show compliance with the 
standards specified in Sec.86.008-10. The generation and use of NMHC 
credits are subject to the same provisions in paragraphs Sec.86.004-15 
(a) through (k) that apply for NOX plus NMHC credits, except 
as otherwise specified in this section.
    (2) Credits are calculated as NOX or NMHC credits for 
engines certified to separate NOX and NMHC standards. 
NOX plus NMHC credits (including banked credits and credits 
that are generated during years 2007-2009 under the phase-in provisions 
of Sec.86.007-11(g)(1), Sec.86.005-10(a), or Sec.86.008-10(f)(1)) 
may be used to show compliance with 2007 or later NOX 
standards (NOX or NMHC standards for Otto-cycle engines), 
subject to an 0.8 discount factor (e.g., 100 grams of NOX 
plus NMHC credits is equivalent to 80 grams of NOX credits).
    (3) NOX or NMHC (or NOX plus NMHC) credits may 
be exchanged between heavy-duty Otto-cycle engine families

[[Page 476]]

certified to the engine standards of this subpart and heavy-duty Otto-
cycle engine families certified to the chassis standards of subpart S of 
this part, subject to an 0.8 discount factor (e.g., 100 grams of 
NOX (or NOX plus NMHC) credits generated from 
engines would be equivalent to 80 grams of NOX credits if 
they are used in the vehicle program of subpart S, and vice versa).
    (4) Credits that were previously discounted when they were banked 
according to paragraph (c) of Sec.86.004-15, are subject to an 
additional discount factor of 0.888 instead of the 0.8 discount factor 
otherwise required by paragraph (m)(2) or (m)(3) of this section. This 
results in a total discount factor of 0.8 (0.9 x 0.888 = 0.8).
    (5) For diesel engine families, the combined number of engines 
certified to FELs higher than 0.50 g/bhp-hr using banked NOX 
(and/or NOX plus NMHC) credits in any given model year may 
not exceed 10 percent of the manufacturer's U.S.-directed production of 
engines in all heavy-duty diesel engine families for that model year.
    (6) The FEL must be expressed to the same number of decimal places 
as the standard (generally, one-hundredth of a gram per brake 
horsepower-hour). For engines certified to standards expressed only one-
tenth of a gram per brake horsepower-hour, if the FEL is below 1.0, then 
add a zero to the standard in the second decimal place and express the 
FEL to nearest one-hundredth of a gram per brake horsepower-hour.
    (7) Credits are to be rounded to the nearest one-hundredth of a 
Megagram using ASTM E29-93a (Incorporated by reference at Sec.86.1).
    (8) Credits generated for 2007 and later model year diesel engine 
families, or generated for 2008 and later model year Otto-cycle engine 
families are not discounted (except as specified in paragraph (m)(2) or 
(m)(3) of this section), and do not expire.
    (9) For the purpose of using or generating credits during a phase-in 
of new standards, a manufacturer may elect to split an engine family 
into two subfamilies (e.g., one which uses credits and one which 
generates credits). The manufacturer must indicate in the application 
for certification that the engine family is to be split, and may assign 
the numbers and configurations of engines within the respective 
subfamilies at any time prior to the submission of the end-of-year 
report required by Sec.86.001-23.
    (i) Manufacturers certifying a split diesel engine family to both 
the Phase 1 and Phase 2 standards with equally sized subfamilies may 
exclude the engines within that split family from end-of-year 
NOX (or NOX + NMHC) ABT calculations, provided 
that neither subfamily generates credits for use by other engine 
families, or uses banked credits, or uses averaging credits from other 
engine families. All of the engines in that split family must be 
excluded from the phase-in calculations of Sec.86.007-11(g)(1) (both 
from the number of engines complying with the standards being phased-in 
and from the total number of U.S.-directed production engines.)
    (ii) Manufacturers certifying a split Otto-cycle engine family to 
both the Phase 1 and Phase 2 standards with equally sized subfamilies 
may exclude the engines within that split family from end-of-year 
NOX (or NOX + NMHC) ABT calculations, provided 
that neither subfamily generates credits for use by other engine 
families, or uses banked credits, or uses averaging credits from other 
engine families. All of the engines in that split family must be 
excluded from the phase-in calculations of Sec.86.008-10(f)(1) (both 
from the number of engines complying with the standards being phased-in 
and from the total number of U.S.-directed production engines.)
    (iii) Manufacturers certifying a split engine family may label all 
of the engines within that family with a single NOX or 
NOX + NMHC FEL. The FEL on the label will apply for all SEA 
or other compliance testing.
    (iv) Notwithstanding the provisions of paragraph (m)(9)(iii) of this 
section, for split families, the NOX FEL shall be used to 
determine applicability of the provisions of Sec. Sec.86.007-
11(a)(3)(ii), (a)(4)(i)(B), and (h)(1), and 86.008-10(g).
    (10) For model years 2007 through 2009, to be consistent with the 
phase-in provisions of Sec.86.007-11(g)(1), credits generated from 
engines in one diesel engine service class (e.g., light-heavy

[[Page 477]]

duty diesel engines) may be used for averaging by engines in a different 
diesel engine service class, provided the credits are calculated for 
both engine families using the conversion factor and useful life of the 
engine family using the credits, and the engine family using the credits 
is certified to the standards listed in Sec.86.007-11(a)(1). Banked or 
traded credits may not be used by any engine family in a different 
service class than the service class of the engine family generating the 
credits.

level of any family particulate emission limit by demonstrating 
compliance with the new limit as described in Sec.86.094-28(a)(6), 
Sec.86.094-28(b)(5)(i), or Sec.86.004-28(c)(5)(i). New certificates 
issued under this paragraph will be applicable only for vehicles (or 
engines) produced subsequent to the date of issuance.
    (iv) For light-duty trucks or HDEs included in the applicable 
NOX averaging program, the manufacturer may at any time 
during production elect to change the level of any family NOX 
emission limit by demonstrating compliance with the new limit as 
described in Sec.86.094-28(b)(5)(ii) or Sec.86.004-28(c)(5)(ii). New 
certificates issued under this paragraph will be applicable only for 
vehicles (or engines) produced subsequent to the day of issue.
    (4)-(5) [Reserved]
    (6) Catalyst-equipped vehicles, otherwise covered by a certificate, 
which are driven outside the United States, Canada, and Mexico will be 
presumed to have been operated on leaded gasoline resulting in 
deactivation of the catalysts. If these vehicles are imported or offered 
for importation without retrofit of the catalyst, they will be 
considered not to be within the coverage of the certificate unless 
included in a catalyst control program operated by a manufacturer or a 
United States Government agency and approved by the Administrator.
    (7) [Reserved]

section with respect to the vehicles (or engines) belonging to an engine 
family or engine family-evaporative/refueling emission family 
combination (as applicable), all of which comply with all applicable 
standards (or family emission limits, as appropriate).
    (3) If after a review of the test reports and data submitted by the 
manufacturer, data derived from any additional testing conducted 
pursuant to Sec.86.091-29, data or information derived from any 
inspection carried out under Sec.86.094-7(d) or any other pertinent 
data or information, the Administrator determines that one or more test 
vehicles (or test engines) of the certification test fleet do not meet 
applicable standards (or family emission limits, as appropriate), he 
will notify the manufacturer in writing, setting forth the basis for his 
determination. Within 30 days following receipt of the notification, the 
manufacturer may request a hearing on the Administrator's determination. 
The request shall be in writing, signed by an authorized representative 
of the manufacturer and shall include a statement specifying the 
manufacturer's objections to the Administrator's determination and data 
in support of such objections. If, after a review of the request and 
supporting data, the Administrator finds that the request raises a 
substantial factual issue, he shall provide the manufacturer a hearing 
in accordance with Sec.86.078-6 with respect to such issue.
    (4) [Reserved]
    (5) For heavy-duty engines the manufacturer may, at his option, 
proceed with any of the following alternatives with respect to any 
engine family represented by a test engine(s) determined not in 
compliance with applicable standards (or family emission limit, as 
appropriate):
    (i) Request a hearing under Sec.86.078-6; or
    (ii) Delete from the application for certification the engines 
represented by the failing test engine. (Engines so deleted may be 
included in a later request for certification under Sec.86.079-32.) 
The Administrator may then select in place of each failing engine an 
alternate engine chosen in accordance with selection criteria employed 
in selecting the engine that failed; or
    (iii) Modify the test engine and demonstrate by testing that it 
meets applicable standards. Another engine which is in all material 
respect the same as the first engine, as modified, may then be operated 
and tested in accordance with applicable test procedures.
    (6) If the manufacturer does not request a hearing or present the 
required data under paragraphs (b)(4) or (5) of this section (as 
applicable) of this section, the Administrator will deny certification.
    (c)(1) Notwithstanding the fact that any certification vehicle(s) 
(or certification engine(s)) may comply with other provisions of this 
subpart, the Administrator may withhold or deny the issuance of a 
certificate of conformity (or suspend or revoke any such certificate 
which has been issued) with

[[Page 482]]

respect to any such vehicle(s) (or engine(s)) if:
    (i) The manufacturer submits false or incomplete information in his 
application for certification thereof;
    (ii) The manufacturer renders inaccurate any test data which he 
submits pertaining thereto or otherwise circumvents the intent of the 
Act, or of this part with respect to such vehicle (or engine);
    (iii) Any EPA Enforcement Officer is denied access on the terms 
specified in Sec.86.091-7(d) to any facility or portion thereof which 
contains any of the following:
    (A) The vehicle (or engine);
    (B) Any components used or considered for use in its modification or 
buildup into a certification vehicle (or certification engine);
    (C) Any production vehicle (or production engine) which is or will 
be claimed by the manufacturer to be covered by the certificate;
    (D) Any step in the construction of a vehicle (or engine) described 
in paragraph (c)(iii)(C) of this section;
    (E) Any records, documents, reports, or histories required by this 
part to be kept concerning any of the above; or
    (iv) Any EPA Enforcement Officer is denied ``reasonable assistance'' 
(as defined in Sec.86.091-7(d) in examining any of the items listed in 
paragraph (c)(1)(iii) of this section.
    (2) The sanctions of withholding, denying, revoking, or suspending 
of a certificate may be imposed for the reasons in paragraphs (c)(1)(i), 
(ii), (iii), or (iv) of this section only when the infraction is 
substantial.
    (3) In any case in which a manufacturer knowingly submits false or 
inaccurate information or knowingly renders inaccurate or invalid any 
test data or commits any other fraudulent acts and such acts contribute 
substantially to the Administrator's decision to issue a certificate of 
conformity, the Administrator may deem such certificate void ab initio.
    (4) In any case in which certification of a vehicle (or engine) is 
proposed to be withheld, denied, revoked, or suspended under paragraph 
(c)(1)(iii) or (iv) of this section, and in which the Administrator has 
presented to the manufacturer involved reasonable evidence that a 
violation of Sec.86.091-7(d) in fact occurred, the manufacturer, if he 
wishes to contend that, even though the violation occurred, the vehicle 
(or engine) in question was not involved in the violation to a degree 
that would warrant withholding, denial, revocation, or suspension of 
certification under either paragraph (c)(1)(iii) or (iv) of this 
section, shall have the burden of establishing that contention to the 
satisfaction of the Administrator.
    (5) Any revocation or suspension of certification under paragraph 
(c)(1) of this section shall:
    (i) Be made only after the manufacturer concerned has been offered 
an opportunity for a hearing conducted in accordance with Sec.86.078-6 
hereof; and
    (ii) Extend no further than to forbid the introduction into commerce 
of vehicles (or engines) previously covered by the certification which 
are still in the hands of the manufacturer, except in cases of such 
fraud or other misconduct as makes the certification invalid ab initio.
    (6) The manufacturer may request in the form and manner specified in 
paragraph (b)(3) of this section that any determination made by the 
Administrator under paragraph (c)(1) of this section to withhold or deny 
certification be reviewed in a hearing conducted in accordance with 
Sec.86.078-6. If the Administrator finds, after a review of the 
request and supporting data, that the request raises a substantial 
factual issue, he will grant the request with respect to such issue.
    (d) [Reserved]
    (e) For light-duty trucks and heavy-duty engines. (1) 
Notwithstanding the fact that any vehicle configuration or engine family 
may be covered by a valid outstanding certificate of conformity, the 
Administrator may suspend such outstanding certificate of conformity in 
whole or in part with respect to such vehicle or engine configuration or 
engine family if:
    (i) The manufacturer refuses to comply with the provisions of a test 
order issued by the Administrator pursuant to Sec.86.1003; or
    (ii) The manufacturer refuses to comply with any of the requirements 
of Sec.86.1003; or

[[Page 483]]

    (iii) The manufacturer submits false or incomplete information in 
any report or information provided pursuant to the requirements of Sec.
86.1009; or
    (iv) The manufacturer renders inaccurate any test data submitted 
pursuant to Sec.86.1009; or
    (v) Any EPA Enforcement Officer is denied the opportunity to conduct 
activities related to entry and access as authorized in Sec.86.1006 of 
this part and in a warrant or court order presented to the manufacturer 
or the party in charge of a facility in question; or
    (vi) EPA Enforcement Officers are unable to conduct activities 
related to entry and access as authorized in Sec.86.1006 of this part 
because a manufacturer has located a facility in a foreign jurisdiction 
where local law prohibits those activities; or
    (vii) The manufacturer refuses to or in fact does not comply with 
the requirements of Sec. Sec.86.1004(a), 86.1005, 86.1007, 86.1008, 
86.1010, 86.1011, or 86.1013.
    (2) The sanction of suspending a certificate may not be imposed for 
the reasons in paragraph (e)(1) (i), (ii), or (vii) of this section 
where such refusal or denial is caused by conditions and circumstances 
outside the control of the manufacturer which renders it impossible to 
comply with those requirements. Such conditions and circumstances shall 
include, but are not limited to, any uncontrollable factors which result 
in the temporary unavailability of equipment and personnel needed to 
conduct the required tests, such as equipment breakdown or failure or 
illness of personnel, but shall not include failure of the manufacturers 
to adequately plan for and provide the equipment and personnel needed to 
conduct the tests. The manufacturer will bear the burden of establishing 
the presence of the conditions and circumstances required by this 
paragraph.
    (3) The sanction of suspending a certificate may be imposed for the 
reasons outlined in paragraph (e)(1)(iii), (iv), or (v) of this section 
only when the infraction is substantial.
    (4) In any case in which a manufacturer knowingly submitted false or 
inaccurate information or knowingly rendered inaccurate any test data or 
committed any other fraudulent acts, and such acts contributed 
substantially to the Administrator's original decision not to suspend or 
revoke a certificate of conformity in whole or in part, the 
Administrator may deem such certificate void from the date of such 
fraudulent act.
    (5) In any case in which certification of a light-duty truck or 
heavy-duty engine is proposed to be suspended under paragraph (e)(1)(v) 
of this section and in which the Administrator has presented to the 
manufacturer involved reasonable evidence that a violation of Sec.
86.1006 in fact occurred, if the manufacturer wishes to contend that, 
although the violation occurred, the vehicle or engine configuration or 
engine family in question was not involved in the violation to a degree 
that would warrant suspension of certification under paragraph (e)(1)(v) 
of this section, he shall have the burden of establishing that 
contention to the satisfaction of the Administrator.
    (6) Any suspension of certification under paragraph (e)(1) of this 
section shall:
    (i) Be made only after the manufacturer concerned has been offered 
an opportunity for a hearing conducted in accordance with Sec.86.1014; 
and
    (ii) Not apply to vehicles or engines no longer in the hands of the 
manufacturer.
    (7) Any voiding of a certificate of conformity under paragraph 
(e)(4) of this section shall be made only after the manufacturer 
concerned has been offered an opportunity for a hearing conducted in 
accordance with Sec.86.1014.
    (8) Any voiding of the certificate under paragraph (a) (10) or (11) 
of this section will be made only after the manufacturer concerned has 
been offered an opportunity for a hearing conducted in accordance with 
Sec.86.1014.

heavy-duty engines and vehicles. Starting in model year 2021, this 
section applies to light

[[Page 484]]

HDE and medium HDE, but it no longer applies to heavy HDE (see 40 CFR 
1036.140(a) and 1036.150(c)).
    (a)(1) Exhaust emissions from new 2008 and later model year Otto-
cycle HDEs shall not exceed:
    (i)(A) Oxides of Nitrogen (NOX). 0.20 grams per brake horsepower-
hour (0.075 grams per megajoule).
    (B) A manufacturer may elect to include any or all of its Otto-cycle 
HDE families in any or all of the NOX and NOX plus 
NMHC emissions ABT programs for HDEs, within the restrictions described 
in Sec.86.008-15 or Sec.86.004-15. If the manufacturer elects to 
include engine families in any of these programs, the NOX FEL 
may not exceed 0.50 grams per brake horsepower-hour (0.26 grams per 
megajoule). This ceiling value applies whether credits for the family 
are derived from averaging, banking, or trading programs. The 
NOX FEL cap is 0.80 for model years before 2011 for 
manufacturers choosing to certify to the 1.5 g/bhp-hr NOX + 
NMHC standard in 2003 or 2004, in accordance with Sec.86.005-10(f).
    (ii)(A) Nonmethane hydrocarbon (NMHC) for engines fueled with 
gasoline. 0.14 grams per brake horsepower-hour (0.052 grams per 
megajoule).
    (B) Nonmethane-nonethane hydrocarbon (NMNEHC) for engines fueled 
with natural gas or liquefied petroleum gas. 0.14 grams per brake 
horsepower-hour (0.052 grams per megajoule).
    (C) Nonmethane hydrocarbon equivalent (NMHCE) for engines fueled

megajoule).
    (D) A manufacturer may elect to include any or all of its Otto-cycle 
HDE families in any or all of the hydrocarbon emission ABT programs for 
HDEs, within the restrictions described in Sec.86.007-15 or Sec.
86.004-15. If the manufacturer elects to include engine families in any 
of these programs, the hydrocarbon FEL may not exceed 0.30 grams per 
brake horsepower-hour. This ceiling value applies whether credits for 
the family are derived from averaging, banking, or trading programs. The 
hydrocarbon FEL cap is 0.40 for model years before 2011 for 
manufacturers choosing to certify to the 1.5 g/bhp-hr NOX + 
HC in 2004, as allowed in Sec.86.005-10.
    (iii) Carbon monoxide. 14.4 grams per brake horsepower-hour (5.36 
grams per megajoule).
    (iv) Particulate. 0.01 grams per brake horsepower-hour (0.0037grams 
per megajoule).
    (2) The standards set forth in paragraph (a)(1) of this section 
refer to the exhaust emitted over the operating schedule set forth in 
paragraph (f)(1) of Appendix I to this part, and measured and calculated 
in accordance with the procedures set forth in subpart N or P of this 
part:
    (i) Perform the test interval set forth in paragraph (f)(1) of 
Appendix I of this part with a cold-start according to 40 CFR part 1065, 
subpart F. This is the cold-start test interval.
    (ii) Shut down the engine after completing the test interval and 
allow 20 minutes to elapse. This is the hot soak.
    (iii) Repeat the test interval. This is the hot-start test interval.
    (iv) Calculate the total emission mass of each constituent, m, and 
the total work, W, over each test interval according to 40 CFR 1065.650.
    (v) Determine your engine's brake-specific emissions using the 
following calculation, which weights the emissions from the cold-start 
and hot-start test intervals:

    (3)-(4) [Reserved]
    (b) This paragraph (b) applies as specified in 40 CFR 1037.103. 
Evaporative emissions from heavy-duty vehicles shall not exceed the 
following standards when measured using the test procedures specified in 
40 CFR 1037.501. The standards apply equally to certification and in-use 
vehicles. The spitback standard also applies to newly assembled 
vehicles. For certification vehicles only, manufacturers may conduct 
testing to quantify a level of nonfuel background emissions for an 
individual test vehicle. Such a demonstration must include a description 
of the source(s) of emissions and an estimated decay rate. The 
demonstrated level of nonfuel background emissions may be subtracted 
from emission test results from certification vehicles if

    (f) [Reserved]
    (g) Model year 2018 and later engines that will be installed in 
specialty vehicles as allowed by 40 CFR 1037.605 may meet alternate 
emission standards as follows:
    (1) The engines must be of a configuration that is identical to one 
that is certified under 40 CFR part 1048 to the Blue Sky standards under 
40 CFR 1048.140.
    (2) Except as specified in this paragraph (g), engines certified 
under this paragraph (g) must meet all the requirements that apply under 
40 CFR part 1048 instead of the comparable provisions in this subpart A. 
Before shipping engines under this section, you must have written 
assurance from the vehicle manufacturers that they need a certain number 
of exempted engines under this section. In your annual production report 
under 40 CFR 1048.250, count these engines separately and identify the 
vehicle manufacturers that will be installing them. Treat these engines 
as part of the corresponding engine family under 40 CFR part 1048 for 
compliance purposes such as testing production engines, in-use testing, 
defect reporting, and recall.
    (3) The engines must be labeled as described in Sec.86.095-35, 
with the following statement instead of the one specified in Sec.
86.095-35(a)(3)(iii)(H): ``This engine conforms to alternate standards 
for specialty vehicles under 40 CFR 86.008-10(g)''. Engines certified 
under this paragraph (g) may not have the label specified for nonroad 
engines in 40 CFR part 1048 or any other label identifying them as 
nonroad engines.
    (4) In a separate application for a certificate of conformity, 
identify the corresponding nonroad engine family, describe the label 
required under this paragraph (g), state that you meet applicable 
diagnostic requirements under 40 CFR part 1048, and identify your 
projected U.S.-directed production volume.
    (5) No additional certification fee applies for engines certified 
under this paragraph (g).
    (6) Engines certified under this paragraph (g) may not generate or 
use emission credits under this part. The vehicles in which these 
engines are installed may generate or use emission credits as described 
in 40 CFR part 1037.
    (7) Engines may instead meet standards for heavy-duty highway 
engines in California, as demonstrated by an Executive Order issued by 
the California Air Resources Board.

Sec.86.010-2  Definitions.

    The definitions of Sec.86.004-2 continue to apply to 2004 and 
later model year vehicles. The definitions listed in this section apply 
beginning with the 2010 model year.
    DTC means diagnostic trouble code.
    Engine or engine system as used in Sec. Sec.86.007-17, 86.007-30, 
86.010-18, and 86.010-38 means the engine, fuel system, induction 
system, aftertreatment system, and everything that makes up the system 
for which an engine manufacturer has received a certificate of 
conformity.
    Engine start as used in Sec.86.010-18 means the point when the 
engine reaches a speed 150 rpm below the normal, warmed-up idle speed 
(as determined in the drive position for vehicles equipped with an 
automatic transmission). For hybrid vehicles or for engines employing 
alternative engine start hardware or strategies (e.g., integrated 
starter and generators.), the manufacturer may use an alternative 
definition for engine start (e.g., key-on) provided the alternative 
definition is based on equivalence to an engine start for a conventional 
vehicle.
    Functional check, in the context of onboard diagnostics, means 
verifying that a component and/or system that receives information from 
a control computer responds properly to a command from the control 
computer.
    Ignition cycle as used in Sec.86.010-18 means a cycle that begins 
with engine start, meets the engine start definition for at least two 
seconds plus or minus

[[Page 487]]

one second, and ends with engine shutoff.
    Limp-home operation as used in Sec.86.010-18 means an operating 
mode that an engine is designed to enter upon determining that normal 
operation cannot be maintained. In general, limp-home operation implies 
that a component or system is not operating properly or is believed to 
be not operating properly.
    Malfunction means the conditions have been met that require the 
activation of an OBD malfunction indicator light and storage of a DTC.
    MIL-on DTC means the diagnostic trouble code stored when an OBD 
system has detected and confirmed that a malfunction exists (e.g., 
typically on the second drive cycle during which a given OBD monitor has 
evaluated a system or component). Industry standards may refer to this 
as a confirmed or an active DTC.
    Onboard Diagnostics (OBD) group means a combination of engines, 
engine families, or engine ratings that use the same OBD strategies and 
similar calibrations.
    Pending DTC means the diagnostic trouble code stored upon the 
detection of a potential malfunction.
    Permanent DTC means a DTC that corresponds to a MIL-on DTC and is 
stored in non-volatile random access memory (NVRAM). A permanent DTC can 
only be erased by the OBD system itself and cannot be erased through 
human interaction with the OBD system or any onboard computer.
    Potential malfunction means that conditions have been detected that 
meet the OBD malfunction criteria but for which more drive cycles are 
allowed to provide further evaluation prior to confirming that a 
malfunction exists.
    Previous-MIL-on DTC means a DTC that corresponds to a MIL-on DTC but 
is distinguished by representing a malfunction that the OBD system has 
determined no longer exists but for which insufficient operation has 
occurred to satisfy the DTC erasure provisions.
    Rationality check, in the context of onboard diagnostics, means 
verifying that a component that provides input to a control computer 
provides an accurate input to the control computer while in the range of 
normal operation and when compared to all other available information.
    Similar conditions, in the context of onboard diagnostics, means 
engine conditions having an engine speed within 375 rpm, load conditions 
within 20 percent, and the same warm up status (i.e., cold or hot). The 
manufacturer may use other definitions of similar conditions based on 
comparable timeliness and reliability in detecting similar engine 
operation.

[74 FR 8369, Feb. 24, 2009]



Sec.86.010-18  On-board Diagnostics for engines used in applications
greater than 14,000 pounds GVWR.

    (a) General. According to the implementation schedule shown in 
paragraph (o) of this section, heavy-duty engines intended for use in a 
heavy-duty vehicle weighing more than 14,000 pounds GVWR must be 
equipped with an on-board diagnostic (OBD) system capable of monitoring 
all emission-related engine systems or components during the life of the 
engine. The OBD system is required to detect all malfunctions specified 
in paragraphs (g), (h), and (i) of this Sec.86.010-18 although the OBD 
system is not required to use a unique monitor to detect each of those 
malfunctions.
    (1) When the OBD system detects a malfunction, it must store a 
pending, a MIL-on, or a previous-MIL-on diagnostic trouble code (DTC) in 
the onboard computer's memory. A malfunction indicator light (MIL) must 
also be activated as specified in paragraph (b) of this section.
    (2) Data link connector. (i) For model years 2010 through 2012, the 
OBD system must be equipped with a data link connector to provide access 
to the stored DTCs as specified in paragraph (k)(2) of this section.
    (ii) For model years 2013 and later, the OBD system must be equipped 
with a standardized data link connector to provide access to the stored 
DTCs as specified in paragraph (k)(2) of this section.
    (3) The OBD system cannot be programmed or otherwise designed to 
deactivate based on age and/or mileage. This requirement does not alter 
existing law and enforcement practice regarding a manufacturer's 
liability for

[[Page 488]]

an engine beyond its regulatory useful life, except where an engine has 
been programmed or otherwise designed so that an OBD system deactivates 
based on age and/or mileage of the engine.
    (4) Drive cycle or driving cycle, in the context of this Sec.
86.010-18, means operation that meets any of the conditions of 
paragraphs (a)(4)(i) through (a)(4)(iv) of this section. Further, for 
OBD monitors that run during engine-off conditions, the period of 
engine-off time following engine shutoff and up to the next engine start 
may be considered part of the drive cycle for the conditions of 
paragraphs (a)(4)(i) and (a)(4)(iv) of this section. For engines/
vehicles that employ engine shutoff OBD monitoring strategies that do 
not require the vehicle operator to restart the engine to continue 
vehicle operation (e.g., a hybrid bus with engine shutoff at idle), the 
manufacturer may use an alternative definition for drive cycle (e.g., 
key-on followed by key-off). Any alternative definition must be based on 
equivalence to engine startup and engine shutoff signaling the beginning 
and ending of a single driving event for a conventional vehicle. For 
engines that are not likely to be routinely operated for long continuous 
periods of time, a manufacturer may also request approval to use an 
alternative definition for drive cycle (e.g., solely based on engine 
start and engine shutoff without regard to four hours of continuous 
engine-on time). Administrator approval of the alternative definition 
will be based on manufacturer-submitted data and/or information 
demonstrating the typical usage, operating habits, and/or driving 
patterns of these vehicles.
    (i) Begins with engine start and ends with engine shutoff;
    (ii) Begins with engine start and ends after four hours of 
continuous engine-on operation;
    (iii) Begins at the end of the previous four hours of continuous 
engine-on operation and ends after four hours of continuous engine-on 
operation; or
    (iv) Begins at the end of the previous four hours of continuous 
engine-on operation and ends with engine shutoff.
    (5) As an alternative to demonstrating compliance with the 
provisions of paragraphs (b) through (l) of this Sec.86.010-18, a 
manufacturer may demonstrate how the OBD system they have designed to 
comply with California OBD requirements for engines used in applications 
greater than 14,000 pounds also complies with the intent of the 
provisions of paragraphs (b) through (l) of this section. To make use of 
this alternative, the manufacturer must demonstrate to the Administrator 
how the OBD system they intend to certify meets the intent behind all of 
the requirements of this section, where applicable (e.g., paragraph (h) 
of this section would not apply for a diesel fueled/CI engine). 
Furthermore, if making use of this alternative, the manufacturer must 
comply with the specific certification documentation requirements of 
paragraph (m)(3) of this section.
    (6) Temporary provisions to address hardship due to unusual 
circumstances. (i) After considering the unusual circumstances, the 
Administrator may permit the manufacturer to introduce into U.S. 
commerce engines that do not comply with this Sec.86.010-18 for a 
limited time if all the following conditions apply:
    (A) Unusual circumstances that are clearly outside the 
manufacturer's control prevent compliance with the requirements of this 
Sec.86.010-18.
    (B) The manufacturer exercised prudent planning and was not able to 
avoid the violation and has taken all reasonable steps to minimize the 
extent of the nonconformity.
    (C) No other allowances are available under the regulations in this 
chapter to avoid the impending violation.
    (ii) To apply for an exemption, the manufacturer must send to the 
Administrator a written request as soon as possible before being in 
violation. In the request, the manufacturer must show that all the 
conditions and requirements of paragraph (a)(6)(i) of this section are 
met.
    (iii) The request must also include a plan showing how all the 
applicable requirements will be met as quickly as possible.
    (iv) The manufacturer shall give the Administrator other relevant 
information upon request.
    (v) The Administrator may include additional conditions on an 
approval

[[Page 489]]

granted under the provisions of this paragraph (a)(6), including 
provisions that may require field repair at the manufacturer's expense 
to correct the noncompliance.
    (vi) Engines sold as non-compliant under this temporary hardship 
provision must display ``non-OBD'' in the data stream as required under 
paragraph (k)(4)(ii) of this section. Upon correcting the noncompliance, 
the data stream value must be updated accordingly.
    (b) Malfunction indicator light (MIL) and Diagnostic Trouble Codes 
(DTC). The OBD system must incorporate a malfunction indicator light 
(MIL) or equivalent and must store specific types of diagnostic trouble 
codes (DTC). Unless otherwise specified, all provisions of this 
paragraph (b) apply for 2010 and later model years.
    (1) MIL specifications. (i) For model years 2013 and later, the MIL 
must be located on the primary driver's side instrument panel and be of 
sufficient illumination and location to be readily visible under all 
lighting conditions. The MIL must be amber (yellow) in color; the use of 
red for the OBD-related MIL is prohibited. More than one general purpose 
malfunction indicator light for emission-related problems shall not be 
used; separate specific purpose warning lights (e.g., brake system, 
fasten seat belt, oil pressure, etc.) are permitted. When activated, the 
MIL shall display the International Standards Organization (ISO) engine 
symbol.
    (ii) The OBD system must activate the MIL when the ignition is in 
the key-on/engine-off position before engine cranking to indicate that 
the MIL is functional. The MIL shall be activated continuously during 
this functional check for a minimum of 5 seconds. During this MIL key-on 
functional check, the data stream value (see paragraph (k)(4)(ii) of 
this section) for MIL status must indicate ``commanded off'' unless the 
OBD system has detected a malfunction and has stored a MIL-on DTC. This 
MIL key-on functional check is not required during vehicle operation in 
the key-on/engine-off position subsequent to the initial engine cranking 
of an ignition cycle (e.g., due to an engine stall or other non-
commanded engine shutoff).
    (iii) As an option, the MIL may be used to indicate readiness status 
(see paragraph (k)(4)(i) of this section) in a standardized format in 
the key-on/engine-off position.
    (iv) A manufacturer may also use the MIL to indicate which, if any, 
DTCs are currently stored (e.g., to ``blink'' the stored DTCs). Such use 
must not activate unintentionally during routine driver operation.
    (v) For model years 2013 and later, the MIL required by this 
paragraph (b) must not be used in any other way than is specified in 
this section.
    (2) MIL activation and DTC storage protocol. (i) Within 10 seconds 
of detecting a potential malfunction, the OBD system must store a 
pending DTC that identifies the potential malfunction.
    (ii) If the potential malfunction is again detected before the end 
of the next drive cycle during which monitoring occurs (i.e., the 
potential malfunction has been confirmed as a malfunction), then within 
10 seconds of such detection the OBD system must activate the MIL 
continuously and store a MIL-on DTC (systems using the SAE J1939 
standard protocol specified in paragraph (k)(1) of this section may 
either erase or retain the pending DTC in conjunction with storing the 
MIL-on DTC). If the potential malfunction is not detected before the end 
of the next drive cycle during which monitoring occurs (i.e., there is 
no indication of the malfunction at any time during the drive cycle), 
the corresponding pending DTC should be erased at the end of the drive 
cycle. Similarly, if a malfunction is detected for the first time and 
confirmed on a given drive cycle without need for further evaluation, 
then within 10 seconds of such detection the OBD system must activate 
the MIL continuously and store a MIL-on DTC (again, systems using the 
SAE J1939 standard protocol specified in paragraph (k)(1) of this 
section may optionally store a pending DTC in conjunction with storing 
the MIL-on DTC).
    (iii) A manufacturer may request Administrator approval to employ 
alternative statistical MIL activation and DTC storage protocols to 
those specified in paragraphs (b)(2)(i) and (b)(2)(ii) of this section. 
Approval will depend upon the manufacturer providing data

[[Page 490]]

and/or engineering evaluations that demonstrate that the alternative 
protocols can evaluate system performance and detect malfunctions in a 
manner that is equally effective and timely. Strategies requiring on 
average more than six drive cycles for MIL activation will not be 
accepted.
    (iv) The OBD system must store a ``freeze frame'' of the operating 
conditions (as defined in paragraph (k)(4)(iii) of this section) present 
upon detecting a malfunction or a potential malfunction. In the event 
that a pending DTC has matured to a MIL-on DTC, the manufacturer shall 
either retain the currently stored freeze frame conditions or replace 
the stored freeze frame with freeze frame conditions regarding the MIL-
on DTC. Any freeze frame stored in conjunction with any pending DTC or 
MIL-on DTC should be erased upon erasure of the corresponding DTC.
    (v) If the engine enters a limp-home mode of operation that can 
affect emissions or the performance of the OBD system, or in the event 
of a malfunction of an onboard computer(s) itself that can affect the 
performance of the OBD system, the OBD system must activate the MIL and 
store a MIL-on DTC within 10 seconds to inform the vehicle operator. If 
the limp-home mode of operation is recoverable (i.e., operation 
automatically returns to normal at the beginning of the following 
ignition cycle), the OBD system may wait to activate the MIL and store 
the MIL-on DTC if the limp-home mode of operation is again entered 
before the end of the next ignition cycle rather than activating the MIL 
within 10 seconds on the first drive cycle during which the limp-home 
mode of operation is entered.
    (vi) Before the end of an ignition cycle, the OBD system must store 
a permanent DTC(s) that corresponds to any stored MIL-on DTC(s).
    (3) MIL deactivation and DTC erasure protocol--(i) Deactivating the 
MIL. Except as otherwise provided for in paragraphs (g)(2)(iv)(E) and 
(g)(6)(iv)(B) of this section for diesel misfire malfunctions and empty 
reductant tanks, and paragraphs (h)(1)(iv)(F), (h)(2)(viii), and 
(h)(7)(iv)(B) of this section for gasoline fuel system, misfire, and 
evaporative system malfunctions, once the MIL has been activated, it may 
be deactivated after three subsequent sequential drive cycles during 
which the monitoring system responsible for activating the MIL functions 
and the previously detected malfunction is no longer present and 
provided no other malfunction has been detected that would independently 
activate the MIL according to the requirements outlined in paragraph 
(b)(2) of this section.
    (ii) Erasing a MIL-on DTC. The OBD system may erase a MIL-on DTC if 
the identified malfunction has not again been detected in at least 40 
engine warm up cycles and the MIL is presently not activated for that 
malfunction. The OBD system may also erase a MIL-on DTC upon 
deactivating the MIL according to paragraph (b)(3)(i) of this section 
provided a previous-MIL-on DTC is stored upon erasure of the MIL-on DTC. 
The OBD system may erase a previous-MIL-on DTC if the identified 
malfunction has not again been detected in at least 40 engine warm up 
cycles and the MIL is presently not activated for that malfunction.
    (iii) Erasing a permanent DTC. The OBD system can erase a permanent 
DTC only if:
    (A) The OBD system itself determines that the malfunction that 
caused the corresponding permanent DTC to be stored is no longer present 
and is not commanding activation of the MIL, concurrent with the 
requirements of paragraph (b)(3)(i) of this section which, for purposes 
of this paragraph (b)(3)(iii), shall apply to all monitors.
    (B) All externally erasable DTC information stored in the onboard 
computer has been erased (i.e., through the use of a scan tool or 
battery disconnect) and the monitor of the malfunction that caused the 
permanent DTC to be stored is subject to the minimum ratio requirements 
of paragraph (d) of this section, the OBD system shall erase the 
permanent DTC at the end of a drive cycle if the monitor has run and 
made one or more determinations during a drive cycle that the 
malfunction of the component or the system is not present and has not 
made any determinations within the same

[[Page 491]]

drive cycle that the malfunction is present.
    (C)(1) All externally erasable DTC information stored in the onboard 
computer has been erased (i.e., through the use of a scan tool or 
battery disconnect) and the monitor of the malfunction that caused the 
permanent DTC to be stored is not subject to the minimum ratio 
requirements of paragraph (d) of this section, the OBD system shall 
erase the permanent DTC at the end of a drive cycle provided the 
following two criteria have independently been satisfied:
    (i) The monitor has run and made one or more determinations during a 
drive cycle that the malfunction is no longer present and has not made 
any determinations within the same drive cycle that the malfunction is 
present; and,
    (ii) The monitor does not detect a malfunction on a drive cycle and 
the criteria of paragraph (d)(4)(ii) of this section has been met.
    (2) These two separate criteria may be met on the same or different 
drive cycles provided the monitor never detects a malfunction during 
either drive cycle, and if criteria (b)(3)(iii)(C)(1)(i) happens first 
then no malfunction may be detected before criteria 
(b)(3)(iii)(C)(1)(ii) occurs. If a malfunction occurs after criteria 
(b)(3)(iii)(C)(1)(i) then criteria (b)(3)(iii)(C)(1)(i) must be 
satisfied again. For the second criterion, the manufacturer must exclude 
any temperature and/or elevation provisions of paragraph (d)(4)(ii) of 
this section. For this paragraph (b)(3)(iii)(C), monitors required to 
use ``similar conditions'' as defined in Sec.86.010-2 to store and 
erase pending and MIL-on DTCs cannot require that the similar conditions 
be met prior to erasure of the permanent DTC.
    (D) The Administrator shall allow monitors subject to paragraph 
(b)(3)(iii)(B) of this section to use the criteria of paragraph 
(b)(3)(iii)(C) of this section in lieu of paragraph (b)(3)(iii)(B). 
Further, manufacturers may request Administrator approval to use 
alternative criteria to erase the permanent DTC. The Administrator shall 
approve alternate criteria that will not likely require driving 
conditions that are longer and more difficult to meet than those 
required under paragraph (b)(3)(iii)(C) of this section and do not 
require access to enhanced scan tools to determine conditions necessary 
to erase the permanent DTC.
    (4) Exceptions to MIL and DTC requirements. (i) If a limp-home mode 
of operation causes a overt indication (e.g., activation of a red engine 
shut-down warning light) such that the driver is certain to respond and 
have the problem corrected, a manufacturer may choose not to activate 
the MIL as required by paragraph (b)(2)(v) of this section. 
Additionally, if an auxiliary emission control device has been properly 
activated as approved by the Administrator, a manufacturer may choose 
not to activate the MIL.
    (ii) For gasoline engines, a manufacturer may choose to meet the MIL 
and DTC requirements in Sec.86.007-17 in lieu of meeting the 
requirements of paragraph (b) of this Sec.86.010-18.
    (c) Monitoring conditions. The OBD system must monitor and detect 
the malfunctions specified in paragraphs (g), (h), and (i) of this 
section under the following general monitoring conditions. The more 
specific monitoring conditions of paragraph (d) of this section are 
sometimes required according to the provisions of paragraphs (g), (h), 
and (i) of this section.
    (1) As specifically provided for in paragraphs (g), (h), and (i) of 
this section, the monitoring conditions for detecting malfunctions must 
be technically necessary to ensure robust detection of malfunctions 
(e.g., avoid false passes and false indications of malfunctions); 
designed to ensure monitoring will occur under conditions that may 
reasonably be expected to be encountered in normal vehicle operation and 
normal vehicle use; and, designed to ensure monitoring will occur during 
the FTP transient test cycle contained in appendix I paragraph (f), of 
this part, or similar drive cycle as approved by the Administrator.
    (2) Monitoring must occur at least once per drive cycle in which the 
monitoring conditions are met.
    (3) Manufacturers may define monitoring conditions that are not 
encountered during the FTP cycle as required in paragraph (c)(1) of this 
section. In doing so, the manufacturer would be

[[Page 492]]

expected to consider the degree to which the requirement to run during 
the FTP transient cycle restricts monitoring during in-use operation, 
the technical necessity for defining monitoring conditions that are not 
encountered during the FTP cycle, whether monitoring is otherwise not 
feasible during the FTP cycle, and/or the ability to demonstrate that 
the monitoring conditions satisfy the minimum acceptable in-use monitor 
performance ratio requirement as defined in paragraph (d) of this 
section.
    (d) In-use performance tracking. As specifically required in 
paragraphs (g), (h), and (i) of this section, the OBD system must 
monitor and detect the malfunctions specified in paragraphs (g), (h), 
and (i) of this section according to the criteria of this paragraph (d). 
The OBD system is not required to track and report in-use performance 
for monitors other than those specifically identified in paragraph 
(d)(1) of this section, but all monitors on applicable model year 
engines are still required to meet the in-use performance ratio as 
specified in paragraph (d)(1)(ii) of this section.
    (1) The manufacturer must implement software algorithms in the OBD 
system to individually track and report the in-use performance of the 
following monitors, if equipped, in the standardized format specified in 
paragraph (e) of this section: NMHC converting catalyst (paragraph 
(g)(5) of this section); NOX converting catalyst (paragraph 
(g)(6) of this section); gasoline catalyst (paragraph (h)(6) of this 
section); exhaust gas sensor (paragraph (g)(9) of this section) or 
paragraph (h)(8) of this section); evaporative system (paragraph (h)(7) 
of this section); EGR system (paragraph (g)(3) of this section or (h)(3) 
of this section); VVT system (paragraph (g)(10) of this section or 
(h)(9) of this section); secondary air system (paragraph (h)(5) of this 
section); DPF system (paragraph (g)(8) of this section); boost pressure 
control system (paragraph (g)(4) of this section); and, NOX 
adsorber system (paragraph (g)(7) of this section).
    (i) The manufacturer shall not use the calculated ratio specified in 
paragraph (d)(2) of this section or any other indication of monitor 
frequency as a monitoring condition for a monitor (e.g., using a low 
ratio to enable more frequent monitoring through diagnostic executive 
priority or modification of other monitoring conditions, or using a high 
ratio to enable less frequent monitoring).
    (ii) For model years 2013 and later, manufacturers must define 
monitoring conditions that, in addition to meeting the criteria in 
paragraphs (c)(1) and (d)(1) of this section, ensure that the monitor 
yields an in-use performance ratio (as defined in paragraph (d)(2) of 
this section) that meets or exceeds the minimum acceptable in-use 
monitor performance ratio of 0.100 for all monitors specifically 
required in paragraphs (g), (h), and (i) of this section to meet the 
monitoring condition requirements of this paragraph (d).
    (iii) If the most reliable monitoring method developed requires a 
lower ratio for a specific monitor than that specified in paragraph 
(d)(1)(ii) of this section, the Administrator may lower the minimum 
acceptable in-use monitoring performance ratio.
    (2) In-use performance ratio definition. For monitors required to 
meet the requirements of paragraph (d) of this section, the performance 
ratio must be calculated in accordance with the specifications of this 
paragraph (d)(2).
    (i) The numerator of the performance ratio is defined as the number 
of times a vehicle has been operated such that all monitoring conditions 
have been encountered that are necessary for the specific monitor to 
detect a malfunction.
    (ii) The denominator is defined as the number of times a vehicle has 
been operated in accordance with the provisions of paragraph (d)(4) of 
this section.
    (iii) The performance ratio is defined as the numerator divided by 
the denominator.
    (3) Specifications for incrementing the numerator. (i) Except as 
provided for in paragraph (d)(3)(v) of this section, the numerator, when 
incremented, must be incremented by an integer of one. The numerator 
shall not be incremented more than once per drive cycle.
    (ii) The numerator for a specific monitor must be incremented within 
10

[[Page 493]]

seconds if and only if the following criteria are satisfied on a single 
drive cycle:
    (A) Every monitoring condition has been satisfied that is necessary 
for the specific monitor to detect a malfunction and store a pending 
DTC, including applicable enable criteria, presence or absence of 
related DTCs, sufficient length of monitoring time, and diagnostic 
executive priority assignments (e.g., diagnostic ``A'' must execute 
prior to diagnostic ``B''). For the purpose of incrementing the 
numerator, satisfying all the monitoring conditions necessary for a 
monitor to determine that the monitor is not malfunctioning shall not, 
by itself, be sufficient to meet this criteria.
    (B) For monitors that require multiple stages or events in a single 
drive cycle to detect a malfunction, every monitoring condition 
necessary for all events to complete must be satisfied.
    (C) For monitors that require intrusive operation of components to 
detect a malfunction, a manufacturer must request approval of the 
strategy used to determine that, had a malfunction been present, the 
monitor would have detected the malfunction. Administrator approval of 
the request will be based on the equivalence of the strategy to actual 
intrusive operation and the ability of the strategy to determine 
accurately if every monitoring condition was satisfied that was 
necessary for the intrusive event to occur.
    (D) For the secondary air system monitor, the criteria in paragraphs 
(d)(3)(ii)(A) through (d)(3)(ii)(C) of this section are satisfied during 
normal operation of the secondary air system. Monitoring during 
intrusive operation of the secondary air system later in the same drive 
cycle for the sole purpose of monitoring shall not, by itself, be 
sufficient to meet these criteria.
    (iii) For monitors that can generate results in a ``gray zone'' or 
``non-detection zone'' (i.e., monitor results that indicate neither a 
properly operating system nor a malfunctioning system) or in a ``non-
decision zone'' (e.g., monitors that increment and decrement counters 
until a pass or fail threshold is reached), the numerator, in general, 
shall not be incremented when the monitor indicates a result in the 
``non-detection zone'' or prior to the monitor reaching a complete 
decision. When necessary, the Administrator will consider data and/or 
engineering analyses submitted by the manufacturer demonstrating the 
expected frequency of results in the ``non-detection zone'' and the 
ability of the monitor to determine accurately, had an actual 
malfunction been present, whether or not the monitor would have detected 
a malfunction instead of a result in the ``non-detection zone.''
    (iv) For monitors that run or complete their evaluation with the 
engine off, the numerator must be incremented either within 10 seconds 
of the monitor completing its evaluation in the engine off state, or 
during the first 10 seconds of engine start on the subsequent drive 
cycle.
    (v) Manufacturers that use alternative statistical MIL activation 
protocols as allowed in paragraph (b)(2)(iii) of this section for any of 
the monitors requiring a numerator, are required to increment the 
numerator(s) appropriately. The manufacturer may be required to provide 
supporting data and/or engineering analyses demonstrating both the 
equivalence of their incrementing approach to the incrementing specified 
in this paragraph (d)(3) for monitors using the standard MIL activation 
protocol, and the overall equivalence of the incrementing approach in 
determining that the minimum acceptable in-use performance ratio of 
paragraph (d)(1)(ii) of this section, if applicable, has been satisfied.
    (4) Specifications for incrementing the denominator. (i) The 
denominator, when incremented, must be incremented by an integer of one. 
The denominator shall not be incremented more than once per drive cycle.
    (ii) The denominator for each monitor must be incremented within 10 
seconds if and only if the following criteria are satisfied on a single 
drive cycle:
    (A) Cumulative time since the start of the drive cycle is greater 
than or equal to 600 seconds while at an elevation of less than 8,000 
feet (2,400 meters) above sea level and at an ambient temperature of 
greater than or equal to 20 degrees Fahrenheit (-7 C);

[[Page 494]]

    (B) Cumulative gasoline engine operation at or above 25 miles per 
hour or diesel engine operation at or above 1,150 rotations per minute 
(diesel engines may use the gasoline criterion for 2010 through 2012 
model years), either of which occurs for greater than or equal to 300 
seconds while at an elevation of less than 8,000 feet (2,400 meters) 
above sea level and at an ambient temperature of greater than or equal 
to 20 degrees Fahrenheit (-7 C); and,
    (C) Continuous engine operation at idle (e.g., accelerator pedal 
released by driver and engine speed less than or equal to 200 rpm above 
normal warmed-up idle (as determined in the drive position for vehicles 
equipped with an automatic transmission) or vehicle speed less than or 
equal to one mile per hour) for greater than or equal to 30 seconds 
while at an elevation of less than 8,000 feet (2,400 meters) above sea 
level and at an ambient temperature of greater than or equal to 20 
degrees Fahrenheit (-7 C).
    (iii) In addition to the requirements of paragraph (d)(4)(ii) of 
this section, the evaporative system monitor denominator(s) may be 
incremented if and only if:
    (A) Cumulative time since the start of the drive cycle is greater 
than or equal to 600 seconds while at an ambient temperature of greater 
than or equal to 40 degrees Fahrenheit (4 C) but less than or equal to 
95 degrees Fahrenheit (35 C); and,
    (B) Engine cold start occurs with the engine coolant temperature 
greater than or equal to 40 degrees Fahrenheit (4 C) but less than or 
equal to 95 degrees Fahrenheit (35 C) and less than or equal to 12 
degrees Fahrenheit (7 C) higher than the ambient temperature.
    (iv) In addition to the requirements of paragraph (d)(4)(ii) of this 
section, the denominator(s) for the following monitors may be 
incremented if and only if the component or strategy is commanded ``on'' 
for a cumulative time greater than or equal to 10 seconds. For purposes 
of determining this commanded ``on'' time, the OBD system shall not 
include time during intrusive operation of any of the components or 
strategies that occurs later in the same drive cycle for the sole 
purpose of monitoring.
    (A) Secondary air system (paragraph (h)(5) of this section).
    (B) Cold start emission reduction strategy (paragraph (h)(4) of this 
section).
    (C) Components or systems that operate only at engine start-up 
(e.g., glow plugs, intake air heaters) and are subject to monitoring 
under ``other emission control systems'' (paragraph (i)(4) of this 
section) or comprehensive component output components (paragraph 
(i)(3)(iii) of this section).
    (v) In addition to the requirements of paragraph (d)(4)(ii) of this 
section, the denominator(s) for the following monitors of output 
components (except those operated only at engine start-up and subject to 
the requirements of paragraph (d)(4)(iv) of this section, may be 
incremented if and only if the component is commanded to function (e.g., 
commanded ``on'', ``opened'', ``closed'', ``locked'') on two or more 
occasions during the drive cycle or for a cumulative time greater than 
or equal to 10 seconds, whichever occurs first:
    (A) Variable valve timing and/or control system (paragraph (g)(10) 
of this section or (h)(9) of this section).
    (B) ``Other emission control systems'' (paragraph (i)(4) of this 
section).
    (C) Comprehensive component output component (paragraph (i)(3) of 
this section) (e.g., turbocharger waste-gates, variable length manifold 
runners).
    (vi) For monitors of the following components, the manufacturer may 
use alternative or additional criteria for incrementing the denominator 
to that set forth in paragraph (d)(4)(ii) of this section. To do so, the 
alternative criteria must be based on equivalence to the criteria of 
paragraph (d)(4)(ii) of this section in measuring the frequency of 
monitor operation relative to the amount of engine operation:
    (A) Engine cooling system input components (paragraph (i)(1) of this 
section).
    (B) ``Other emission control systems'' (paragraph (i)(4) of this 
section).
    (C) Comprehensive component input components that require extended 
monitoring evaluation (paragraph (i)(3) of this section) (e.g., stuck 
fuel level sensor rationality).

[[Page 495]]

    (D) Comprehensive component input component temperature sensor 
rationality monitors (paragraph (i)(3) of this section) (e.g., intake 
air temperature sensor, ambient temperature sensor, fuel temperature 
sensor).
    (E) Diesel particulate filter (DPF) frequent regeneration (paragraph 
(g)(8)(ii)(B) of this section).
    (vii) For monitors of the following components or other emission 
controls that experience infrequent regeneration events, the 
manufacturer may use alternative or additional criteria for incrementing 
the denominator to that set forth in paragraph (d)(4)(ii) of this 
section. To do so, the alternative criteria must be based on equivalence 
to the criteria of paragraph (d)(4)(ii) of this section in measuring the 
frequency of monitor operation relative to the amount of engine 
operation:
    (A) NMHC converting catalyst (paragraph (g)(5) of this section).
    (B) Diesel particulate filter (DPF) (paragraphs (g)(8)(ii)(A) and 
(g)(8)(ii)(D) of this section).
    (viii) In addition to the requirements of paragraph (d)(4)(ii) of 
this section, the denominator(s) for the following monitors shall be 
incremented if and only if a regeneration event is commanded for a time 
greater than or equal to 10 seconds:
    (A) DPF incomplete regeneration (paragraph (g)(8)(ii)(C) of this 
section).
    (B) DPF active/intrusive injection (paragraph (g)(8)(ii)(E) of this 
section).
    (ix) For hybrids that employ alternative engine start hardware or 
strategies (e.g., integrated starter and generators), or alternative 
fuel vehicles (e.g., dedicated, bi-fuel, or dual-fuel applications), the 
manufacturer may use alternative criteria for incrementing the 
denominator to that set forth in paragraph (d)(4)(ii) of this section. 
In general, the Administrator will not approve alternative criteria for 
those hybrids that employ engine shut off only at or near idle and/or 
vehicle stop conditions. To use alternative criteria, the alternative 
criteria must be based on the equivalence to the criteria of paragraph 
(d)(4)(ii) of this section in measuring the amount of vehicle operation 
relative to the measure of conventional vehicle operation.
    (5) Disablement of numerators and denominators. (i) Within 10 
seconds of detecting a malfunction (i.e., a pending or a MIL-on DTC has 
been stored) that disables a monitor for which the monitoring conditions 
in paragraph (d) of this section must be met, the OBD system must stop 
incrementing the numerator and denominator for any monitor that may be 
disabled as a consequence of the detected malfunction. Within 10 seconds 
of the time at which the malfunction is no longer being detected (e.g., 
the pending DTC is erased through OBD system self-clearing or through a 
scan tool command), incrementing of all applicable numerators and 
denominators must resume.
    (ii) Within 10 seconds of the start of a power take-off unit (e.g., 
dump bed, snow plow blade, or aerial bucket, etc.) that disables a 
monitor for which the monitoring conditions in paragraph (d) of this 
section must be met, the OBD system must stop incrementing the numerator 
and denominator for any monitor that may be disabled as a consequence of 
power take-off operation. Within 10 seconds of the time at which the 
power take-off operation ends, incrementing of all applicable numerators 
and denominators must resume.
    (iii) Within 10 seconds of detecting a malfunction (i.e., a pending 
or a MIL-on DTC has been stored) of any component used to determine if 
the criteria of paragraphs (d)(4)(ii) and (d)(4)(iii) of this section 
are satisfied, the OBD system must stop incrementing all applicable 
numerators and denominators. Within 10 seconds of the time at which the 
malfunction is no longer being detected (e.g., the pending DTC is erased 
through OBD system self-clearing or through a scan tool command), 
incrementing of all applicable numerators and denominators must resume.
    (e) Standardized tracking and reporting of in-use monitor 
performance--(1) General. For monitors required to track and report in-
use monitor performance according to paragraph (d) of this section, the 
performance data must be tracked and reported in accordance with the 
specifications in paragraphs (d)(2), (e), and (k)(5) of this section. 
The OBD system must separately report an in-use monitor performance 
numerator

[[Page 496]]

and denominator for each of the following components:
    (i) For diesel engines, NMHC catalyst bank 1, NMHC catalyst bank 2, 
NOX catalyst bank 1, NOX catalyst bank 2, exhaust 
gas sensor bank 1, exhaust gas sensor bank 2, EGR/VVT system, DPF, boost 
pressure control system, and NOX adsorber. The OBD system 
must also report a general denominator and an ignition cycle counter in 
the standardized format specified in paragraphs (e)(5), (e)(6), and 
(k)(5) of this section.
    (ii) For gasoline engines, catalyst bank 1, catalyst bank 2, exhaust 
gas sensor bank 1, exhaust gas sensor bank 2, evaporative leak detection 
system, EGR/VVT system, and secondary air system. The OBD system must 
also report a general denominator and an ignition cycle counter in the 
standardized format specified in paragraphs (e)(5), (e)(6), and (k)(5) 
of this section.
    (iii) For specific components or systems that have multiple monitors 
that are required to be reported under paragraphs (g) and (h) of this 
section (e.g., exhaust gas sensor bank 1 may have multiple monitors for 
sensor response or other sensor characteristics), the OBD system must 
separately track numerators and denominators for each of the specific 
monitors and report only the corresponding numerator and denominator for 
the specific monitor that has the lowest numerical ratio. If two or more 
specific monitors have identical ratios, the corresponding numerator and 
denominator for the specific monitor that has the highest denominator 
must be reported for the specific component.
    (2) Numerator. (i) The OBD system must report a separate numerator 
for each of the applicable components listed in paragraph (e)(1) of this 
section.
    (ii) The numerator(s) must be reported in accordance with the 
specifications in paragraph (k)(5)(ii) of this section.
    (3) Denominator. (i) The OBD system must report a separate 
denominator for each of the applicable components listed in paragraph 
(e)(1) of this section.
    (ii) The denominator(s) must be reported in accordance with the 
specifications in paragraph (k)(5)(ii) of this section.
    (4) Monitor performance ratio. For purposes of determining which 
corresponding numerator and denominator to report as required in 
paragraph (e)(1)(iii) of this section, the ratio must be calculated in 
accordance with the specifications in paragraph (k)(5)(iii) of this 
section.
    (5) Ignition cycle counter. (i) The ignition cycle counter is 
defined as a counter that indicates the number of ignition cycles a 
vehicle has experienced according to the specifications of paragraph 
(e)(5)(ii)(B) of this section. The ignition cycle counter must be 
reported in accordance with the specifications in paragraph (k)(5)(ii) 
of this section.
    (ii) The ignition cycle counter must be incremented as follows:
    (A) The ignition cycle counter, when incremented, must be 
incremented by an integer of one. The ignition cycle counter shall not 
be incremented more than once per ignition cycle.
    (B) The ignition cycle counter must be incremented within 10 seconds 
if and only if the engine exceeds an engine speed of 50 to 150 rpm below 
the normal, warmed-up idle speed (as determined in the drive position 
for engines paired with an automatic transmission) for at least two 
seconds plus or minus one second.
    (iii) Within 10 seconds of detecting a malfunction (i.e., a pending 
or a MIL-on DTC has been stored) of any component used to determine if 
the criteria in paragraph (e)(5)(ii)(B) of this section are satisfied 
(i.e., engine speed or time of operation), the OBD system must stop 
incrementing the ignition cycle counter. Incrementing of the ignition 
cycle counter shall not be stopped for any other condition. Within 10 
seconds of the time at which the malfunction is no longer being detected 
(e.g., the pending DTC is erased through OBD system self-clearing or 
through a scan tool command), incrementing of the ignition cycle counter 
must resume.
    (6) General denominator. (i) The general denominator is defined as a 
measure of the number of times an engine has been operated according to 
the specifications of paragraph (e)(6)(ii)(B) of this section. The 
general denominator must be reported in accordance

[[Page 497]]

with the specifications in paragraph (k)(5)(ii) of this section.
    (ii) The general denominator must be incremented as follows:
    (A) The general denominator, when incremented, must be incremented 
by an integer of one. The general denominator shall not be incremented 
more than once per drive cycle.
    (B) The general denominator must be incremented within 10 seconds if 
and only if the criteria identified in paragraph (d)(4)(ii) of this 
section are satisfied on a single drive cycle.
    (C) Within 10 seconds of detecting a malfunction (i.e., a pending or 
a MIL-on DTC has been stored) of any component used to determine if the 
criteria in paragraph (d)(4)(ii) of this section are satisfied (i.e., 
vehicle speed/load, ambient temperature, elevation, idle operation, or 
time of operation), the OBD system must stop incrementing the general 
denominator. Incrementing of the general denominator shall not be 
stopped for any other condition (e.g., the disablement criteria in 
paragraphs (d)(5)(i) and (d)(5)(ii) of this section shall not disable 
the general denominator). Within 10 seconds of the time at which the 
malfunction is no longer being detected (e.g., the pending DTC is erased 
through OBD system self-clearing or through a scan tool command), 
incrementing of the general denominator must resume.
    (f) Malfunction criteria determination. (1) In determining the 
malfunction criteria for the diesel engine monitors required under 
paragraphs (g) and (i) of this section that are required to indicate a 
malfunction before emissions exceed an emission threshold based on any 
applicable standard, the manufacturer must:
    (i) Use the emission test cycle and standard (i.e., the transient 
FTP or the supplemental emissions test (SET)) determined by the 
manufacturer to provide the most effective monitoring conditions and 
robust monitor provided all other applicable requirements of this 
section are met.
    (ii) Identify in the certification documentation required under 
paragraph (m) of this section, the test cycle and standard determined by 
the manufacturer to be the most stringent for each applicable monitor 
and the most effective and robust for each applicable monitor.
    (iii) If the Administrator reasonably believes that a manufacturer 
has determined incorrectly the test cycle and standard that is most 
stringent or effective, the manufacturer must be able to provide 
emission data and/or engineering analysis supporting their choice of 
test cycle and standard.
    (2) On engines equipped with emission controls that experience 
infrequent regeneration events, a manufacturer need not adjust the 
emission test results that are used to determine the malfunction 
criteria for monitors that are required to indicate a malfunction before 
emissions exceed a certain emission threshold. For each such monitor, 
should the manufacturer choose to adjust the emission test results, the 
manufacturer must adjust the emission result as done in accordance with 
the provisions of Sec.86.004-28(i) with the component for which the 
malfunction criteria are being established having been deteriorated to 
the malfunction threshold. The adjusted emission value must be used for 
purposes of determining whether or not the applicable emission threshold 
is exceeded.
    (i) For purposes of this paragraph (f)(2), regeneration means an 
event, by design, during which emissions levels change while the 
emission control performance is being restored.
    (ii) For purposes of this paragraph (f)(2), infrequent means having 
an expected frequency of less than once per transient FTP cycle.
    (3) For gasoline engines, rather than meeting the malfunction 
criteria specified under paragraphs (h) and (i) of this section, the 
manufacturer may request approval to use an OBD system certified to the 
requirements of Sec.86.007-17. To do so, the manufacturer must 
demonstrate use of good engineering judgment in determining equivalent 
malfunction detection criteria to those required in this section.
    (g) OBD monitoring requirements for diesel-fueled/compression-
ignition engines. The following table shows the thresholds at which 
point certain components or systems, as specified in this paragraph (g), 
are considered malfunctioning.

----------------------------------------------------------------------------------------------------------------
Notes: FEL = Family Emissions Limit; 2.5x std means a multiple of 2.5 times the applicable emissions standard; +
  0.3 means the standard or FEL plus 0.3; 0.05/ + 0.04 means an absolute level of 0.05 or an additive level of
  the standard or FEL plus 0.04, whichever level is higher; these emissions thresholds apply to the monitoring
  requirements of paragraph (g) of this Sec. 86.010-18.

    (1) Fuel system monitoring--(i) General. The OBD system must monitor 
the fuel delivery system to verify that it is functioning properly. The 
individual electronic components (e.g., actuators, valves, sensors, 
pumps) that are used in the fuel system and are not specifically 
addressed in this paragraph (g)(1) must be monitored in accordance with 
the requirements of paragraph (i)(3) of this section.
    (ii) Fuel system malfunction criteria--(A) Fuel system pressure 
control. The OBD system must monitor the fuel system's ability to 
control to the desired fuel pressure. This monitoring must be done 
continuously unless new hardware has to be added, in which case the 
monitoring must be done at least once per drive cycle. The OBD system 
must detect a malfunction of the fuel system's pressure control system 
when the pressure control system is unable to maintain an engine's 
emissions at or below the emissions thresholds for ``other monitors'' as 
shown in Table 1 of this paragraph (g). For engines in which no failure 
or deterioration of the fuel system pressure control could result in an 
engine's emissions exceeding the applicable emissions thresholds, the 
OBD system must detect a malfunction when the system has reached its 
control limits such that the commanded fuel system pressure cannot be 
delivered. For model year 2010 to 2012 engines with a unit injector fuel 
system, this requirement may be met by conducting a functional check of 
the fuel system pressure control in lieu of monitoring for conditions 
that could cause an engine's emissions to exceed the applicable 
emissions thresholds.
    (B) Fuel system injection quantity. The OBD system must detect a 
malfunction of the fuel injection system when the system is unable to 
deliver the commanded quantity of fuel necessary to maintain an engine's 
emissions at or below the emissions thresholds for ``other monitors'' as 
shown in Table 1 of this paragraph (g). For engines in which no failure 
or deterioration of the fuel injection quantity could result in an 
engine's emissions exceeding the applicable emissions thresholds, the 
OBD system must detect a malfunction when the system has reached its 
control limits such that the commanded fuel quantity cannot be 
delivered. For model year 2010 to 2012 engines with a unit injector fuel 
system, this requirement may be met by conducting a

[[Page 499]]

functional check of the fuel system injection quantity in lieu of 
monitoring for conditions that could cause an engine's emissions to 
exceed the applicable emissions thresholds.
    (C) Fuel system injection timing. The OBD system must detect a 
malfunction of the fuel injection system when the system is unable to 
deliver fuel at the proper crank angle/timing (e.g., injection timing 
too advanced or too retarded) necessary to maintain an engine's 
emissions at or below the emissions thresholds for ``other monitors'' as 
shown in Table 1 of this paragraph (g). For engines in which no failure 
or deterioration of the fuel injection timing could result in an 
engine's emissions exceeding the applicable emissions thresholds, the 
OBD system must detect a malfunction when the system has reached its 
control limits such that the commanded fuel injection timing cannot be 
achieved. For model year 2010 to 2012 engines with a unit injector fuel 
system, this requirement may be met by conducting a functional check of 
the fuel system injection timing in lieu of monitoring for conditions 
that could cause an engine's emissions to exceed the applicable 
emissions thresholds.
    (D) Combined Monitoring. For engines with a unit injector fuel 
system, the manufacturer may request Administrator approval to combine 
the malfunction criteria of paragraphs (g)(1)(ii)(A) through 
(g)(1)(ii)(C) of this section into one malfunction provided the 
manufacturer can demonstrate that the combined malfunction will satisfy 
the intent of each separate malfunction criteria. For engines with a 
common rail fuel system, the manufacturer may request Administrator 
approval to combine the malfunction criteria of paragraphs (g)(1)(ii)(B) 
through (g)(1)(ii)(C) of this section into one malfunction provided the 
manufacturer can demonstrate that the combined malfunction will satisfy 
the intent of each separate malfunction criteria.
    (E) Fuel system feedback control. See paragraph (i)(6) of this 
section.
    (iii) Fuel system monitoring conditions. (A) With the exceptions 
noted in this paragraph for unit injector systems, the OBD system must 
monitor continuously for malfunctions identified in paragraphs 
(g)(1)(ii)(A) and (g)(1)(ii)(E) of this section. For 2010 through 2012 
unit injector systems, where functional monitoring is done in lieu of 
emission threshold monitoring for malfunctions identified in paragraph 
(g)(1)(ii)(A) of this section, the manufacturer must define the 
monitoring conditions in accordance with paragraphs (c) and (d) of this 
section. For 2013 and later unit injector systems, the manufacturer must 
define the monitoring conditions for malfunctions identified in 
paragraph (g)(1)(ii)(A) of this section in accordance with paragraphs 
(c) and (d) of this section, with the exception that monitoring must 
occur every time the monitoring conditions are met during the drive 
cycle rather than once per drive cycle as required in paragraph (c)(2) 
of this section.
    (B) For 2010 through 2012, the manufacturer must define the 
monitoring conditions for malfunctions identified in paragraphs 
(g)(1)(ii)(B), (g)(1)(ii)(C), and (g)(1)(ii)(D) of this section in 
accordance with paragraphs (c) and (d) of this section. For 2013 and 
later, the manufacturer must define the monitoring conditions in 
accordance with paragraphs (c) and (d) of this section, with the 
exception that monitoring must occur every time the monitoring 
conditions are met during the drive cycle rather than once per drive 
cycle as required in paragraph (c)(2) of this section.
    (iv) Fuel system MIL activation and DTC storage. The MIL must 
activate and DTCs must be stored according to the provisions of 
paragraph (b) of this section.
    (2) Engine misfire monitoring--(i) General. The OBD system must 
monitor the engine for misfire causing excess emissions.
    (ii) Engine misfire malfunction criteria. (A) The OBD system must be 
capable of detecting misfire occurring in one or more cylinders. To the 
extent possible without adding hardware for this specific purpose, the 
OBD system must also identify the specific misfiring cylinder. If more 
than one cylinder is misfiring continuously, or if more than one but 
less than half of the cylinders are misfiring continuously (if the 
manufacturer can demonstrate the

[[Page 500]]

robustness of their monitor to the approval of the Administrator), a 
separate DTC must be stored indicating that multiple cylinders are 
misfiring. When identifying multiple cylinder misfire, the OBD system is 
not required to identify individually through separate DTCs each of the 
continuously misfiring cylinders.
    (B) For model years 2013 and later, on engines equipped with sensors 
that can detect combustion or combustion quality (e.g., for use in 
engines with homogeneous charge compression ignition (HCCI) control 
systems), the OBD system must detect a misfire malfunction causing 
emissions to exceed the applicable thresholds for ``other monitors'' 
shown in Table 1 of this paragraph (g). To determine what level of 
misfire would cause emissions to exceed the applicable emissions 
thresholds, the manufacturer must determine the percentage of misfire 
evaluated in 1,000 revolution increments that would cause emissions from 
an emission durability demonstration engine to exceed the emissions 
thresholds if the percentage of misfire were present from the beginning 
of the test. To establish this percentage of misfire, the manufacturer 
must use misfire events occurring at equally spaced, complete engine 
cycle intervals, across randomly selected cylinders throughout each 
1,000-revolution increment. If this percentage of misfire is determined 
to be lower than one percent, the manufacturer may set the malfunction 
criteria at one percent. Any misfire malfunction must be detected if the 
percentage of misfire established via this testing is exceeded 
regardless of the pattern of misfire events (e.g., random, equally 
spaced, continuous). The manufacturer may employ other revolution 
increments besides the 1,000 revolution increment. To do so, the 
manufacturer must demonstrate that the strategy is equally effective and 
timely in detecting misfire.
    (iii) Engine misfire monitoring conditions. (A) The OBD system must 
monitor for engine misfire during engine idle conditions at least once 
per drive cycle in which the monitoring conditions for misfire are met. 
The manufacturer must be able to demonstrate via engineering analysis 
and/or data that the self-defined monitoring conditions: are technically 
necessary to ensure robust detection of malfunctions (e.g., avoid false 
passes and false detection of malfunctions); require no more than 1000 
cumulative engine revolutions; and, do not require any single continuous 
idle operation of more than 15 seconds to make a determination that a 
malfunction is present (e.g., a decision can be made with data gathered 
during several idle operations of 15 seconds or less); or, satisfy the 
requirements of paragraph (c) of this section with alternative engine 
operating conditions.
    (B) Manufacturers may employ alternative monitoring conditions 
(e.g., off-idle) provided the manufacturer is able to demonstrate that 
the alternative monitoring ensure equivalent robust detection of 
malfunctions and equivalent timeliness in detection of malfunctions.
    (C) For model years 2013 and later, on engines equipped with sensors 
that can detect combustion or combustion quality the OBD system must 
monitor continuously for engine misfire under all positive torque engine 
speed and load conditions. If a monitoring system cannot detect all 
misfire patterns under all required engine speed and load conditions, 
the manufacturer may request that the Administrator approve the 
monitoring system nonetheless. In evaluating the manufacturer's request, 
the Administrator will consider the following factors: the magnitude of 
the region(s) in which misfire detection is limited; the degree to which 
misfire detection is limited in the region(s) (i.e., the probability of 
detection of misfire events); the frequency with which said region(s) 
are expected to be encountered in-use; the type of misfire patterns for 
which misfire detection is troublesome; and demonstration that the 
monitoring technology employed is not inherently incapable of detecting 
misfire under required conditions (i.e., compliance can be achieved on 
other engines). The evaluation will be based on the following misfire 
patterns: equally spaced misfire occurring on randomly selected 
cylinders; single cylinder continuous misfire; and, paired cylinder 
(cylinders firing at the same crank angle) continuous misfire.

[[Page 501]]

    (iv) Engine misfire MIL activation and DTC storage. (A) General 
requirements for MIL activation and DTC storage are set forth in 
paragraph (b) of this section.
    (B) For model years 2013 and later, on engines equipped with sensors 
that can detect combustion or combustion quality, upon detection of the 
percentage of misfire specified in paragraph (g)(2)(ii)(B) of this 
section, the following criteria shall apply for MIL activation and DTC 
storage: A pending DTC must be stored no later than after the fourth 
exceedance of the percentage of misfire specified in paragraph 
(g)(2)(ii) of this section during a single drive cycle; if a pending 
fault code has been stored, the OBD system must activate the MIL and 
store a MIL-on DTC within 10 seconds if the percentage of misfire 
specified in paragraph (g)(2)(ii) of this section is again exceeded four 
times during the drive cycle immediately following storage of the 
pending DTC, regardless of the conditions encountered during the drive 
cycle, or on the next drive cycle in which similar conditions are 
encountered to those that were occurring when the pending DTC was 
stored. Similar conditions means an engine speed within 375 rpm, engine 
load within 20 percent, and the same warm up status (i.e., cold or hot). 
The Administrator may approve other definitions of similar conditions 
based on comparable timeliness and reliability in detecting similar 
engine operation. The pending DTC may be erased at the end of the next 
drive cycle in which similar conditions are encountered to those that 
were occurring when the pending DTC was stored provided the specified 
percentage of misfire was not again exceeded. The pending DTC may also 
be erased if similar conditions are not encountered during the 80 drive 
cycles immediately following initial detection of the malfunction.
    (C) For model years 2013 and later, on engines equipped with sensors 
that can detect combustion or combustion quality, the OBD system must 
store and erase freeze frame conditions either in conjunction with 
storing and erasing a pending DTC or in conjunction with storing and 
erasing a MIL-on DTC. If freeze frame conditions are stored for a 
malfunction other than a misfire malfunction when a DTC is stored as 
specified in paragraph (g)(2)(iv)(B) of this section, the stored freeze 
frame information must be replaced with the freeze frame information 
regarding the misfire malfunction.
    (D) For model years 2013 and later, on engines equipped with sensors 
that can detect combustion or combustion quality, upon detection of 
misfire according to paragraph (g)(2)(iv)(B) of this section, the OBD 
system must also store the following engine conditions: engine speed, 
load, and warm up status of the first misfire event that resulted in the 
storage of the pending DTC.
    (E) For model years 2013 and later, on engines equipped with sensors 
that can detect combustion or combustion quality, the MIL may be 
deactivated after three sequential drive cycles in which similar 
conditions have been encountered without an exceedance of the specified 
percentage of misfire.
    (3) EGR system monitoring--(i) General. The OBD system must monitor 
the EGR system on engines so equipped for low flow rate, high flow rate, 
and slow response malfunctions. For engines equipped with EGR coolers 
(e.g., heat exchangers), the OBD system must monitor the cooler for 
insufficient cooling malfunctions. The individual electronic components 
(e.g., actuators, valves, sensors) that are used in the EGR system must 
be monitored in accordance with the comprehensive component requirements 
in paragraph (i)(3) of this section.
    (ii) EGR system malfunction criteria--(A) EGR low flow. The OBD 
system must detect a malfunction of the EGR system prior to a decrease 
from the manufacturer's specified EGR flow rate that would cause an 
engine's emissions to exceed the emissions thresholds for ``other 
monitors'' as shown in Table 1 of this paragraph (g). For engines in 
which no failure or deterioration of the EGR system that causes a 
decrease in flow could result in an engine's emissions exceeding the 
applicable emissions thresholds, the OBD system must detect a 
malfunction when the system has reached its control limits such that it 
cannot increase EGR flow to achieve the commanded flow rate.

[[Page 502]]

    (B) EGR high flow. The OBD system must detect a malfunction of the 
EGR system, including a leaking EGR valve (i.e., exhaust gas flowing 
through the valve when the valve is commanded closed) prior to an 
increase from the manufacturer's specified EGR flow rate that would 
cause an engine's emissions to exceed the emissions thresholds for 
``other monitors'' as shown in Table 1 of this paragraph (g). For 
engines in which no failure or deterioration of the EGR system that 
causes an increase in flow could result in an engine's emissions 
exceeding the applicable emissions thresholds, the OBD system must 
detect a malfunction when the system has reached its control limits such 
that it cannot reduce EGR flow to achieve the commanded flow rate.
    (C) EGR slow response. The OBD system must detect a malfunction of 
the EGR system prior to any failure or deterioration in the capability 
of the EGR system to achieve the commanded flow rate within a 
manufacturer-specified time that would cause an engine's emissions to 
exceed the emissions thresholds for ``other monitors'' as shown in Table 
1 of this paragraph (g). The OBD system must monitor both the capability 
of the EGR system to respond to a commanded increase in flow and the 
capability of the EGR system to respond to a commanded decrease in flow.
    (D) EGR system feedback control. See paragraph (i)(6) of this 
section.
    (E) EGR cooler performance. The OBD system must detect a malfunction 
of the EGR cooler prior to a reduction from the manufacturer's specified 
cooling performance that would cause an engine's emissions to exceed the 
emissions thresholds for ``other monitors'' as shown in Table 1 of this 
paragraph (g). For engines in which no failure or deterioration of the 
EGR cooler could result in an engine's emissions exceeding the 
applicable emissions thresholds, the OBD system must detect a 
malfunction when the system has no detectable amount of EGR cooling.
    (iii) EGR system monitoring conditions. (A) The OBD system must 
monitor continuously for malfunctions identified in paragraphs 
(g)(3)(ii)(A), (g)(3)(ii)(B), and (g)(3)(ii)(D) of this section.
    (B) The manufacturer must define the monitoring conditions for 
malfunctions identified in paragraph (g)(3)(ii)(C) of this section in 
accordance with paragraphs (c) and (d) of this section, with the 
exception that monitoring must occur every time the monitoring 
conditions are met during the drive cycle rather than once per drive 
cycle as required in paragraph (c)(2) of this section. For purposes of 
tracking and reporting as required in paragraph (d)(1) of this section, 
all monitors used to detect malfunctions identified in paragraph 
(g)(3)(ii)(C) of this section must be tracked separately but reported as 
a single set of values as specified in paragraph (e)(1)(iii) of this 
section.
    (C) The manufacturer must define the monitoring conditions for 
malfunctions identified in paragraph (g)(3)(ii)(E) of this section in 
accordance with paragraphs (c) and (d) of this section. For purposes of 
tracking and reporting as required in paragraph (d)(1) of this section, 
all monitors used to detect malfunctions identified in paragraph 
(g)(3)(ii)(E) of this section must be tracked separately but reported as 
a single set of values as specified in paragraph (e)(1)(iii) of this 
section.
    (D) The manufacturer may request Administrator approval to disable 
temporarily the EGR system monitor(s) under specific ambient conditions 
(e.g., when freezing may affect performance of the system) or during 
specific operating conditions (e.g., transients, extreme low or high 
flow conditions). The manufacturer must be able to demonstrate via data 
or engineering analysis that a reliable system monitor cannot be run 
when these conditions exist because it cannot robustly distinguish 
between a malfunctioning system and a properly operating system. The 
manufacturer is still required to maintain comprehensive component 
monitoring as required in paragraph (i)(3) of this section.
    (iv) EGR system MIL activation and DTC storage. The MIL must 
activate and DTCs must be stored according to the provisions of 
paragraph (b) of this section.
    (4) Turbo boost control system monitoring--(i) General. The OBD 
system

[[Page 503]]

must monitor the boost pressure control system (e.g., turbocharger) on 
engines so equipped for under and over boost malfunctions. For engines 
equipped with variable geometry turbochargers (VGT), the OBD system must 
monitor the VGT system for slow response malfunctions. For engines 
equipped with charge air cooler systems, the OBD system must monitor the 
charge air cooler system for cooling system performance malfunctions. 
The individual electronic components (e.g., actuators, valves, sensors) 
that are used in the boost pressure control system must be monitored in 
accordance with the comprehensive component requirements in paragraph 
(i)(3) of this section.
    (ii) Turbo boost control system malfunction criteria--(A) Turbo 
underboost. The OBD system must detect a malfunction of the boost 
pressure control system prior to a decrease from the manufacturer's 
commanded boost pressure, or expected boost pressure on engines not 
equipped with a boost pressure control system, that would cause an 
engine's emissions to exceed the emissions thresholds for ``other 
monitors'' as shown in Table 1 of this paragraph (g). For engines in 
which no failure or deterioration of the boost pressure control system 
that causes a decrease in boost could result in an engine's emissions 
exceeding the applicable emissions thresholds, the OBD system must 
detect a malfunction when the system has reached its control limits such 
that it cannot increase boost to achieve the commanded boost pressure.
    (B) Turbo overboost. The OBD system must detect a malfunction of the 
boost pressure control system on engines so equipped prior to an 
increase from the manufacturer's commanded boost pressure that would 
cause an engine's emissions to exceed the emissions thresholds for 
``other monitors'' as shown in Table 1 of this paragraph (g). For 
engines in which no failure or deterioration of the boost pressure 
control system that causes an increase in boost could result in an 
engine's emissions exceeding the applicable emissions thresholds, the 
OBD system must detect a malfunction when the system has reached its 
control limits such that it cannot decrease boost to achieve the 
commanded boost pressure.
    (C) VGT slow response. The OBD system must detect a malfunction 
prior to any failure or deterioration in the capability of the VGT 
system on engines so equipped to achieve the commanded turbocharger 
geometry within a manufacturer-specified time that would cause an 
engine's emissions to exceed the emissions thresholds for ``other 
monitors'' as shown in Table 1 of this paragraph (g). For engines in 
which no failure or deterioration of the VGT system response could 
result in an engine's emissions exceeding the applicable emissions 
thresholds, the OBD system must detect a malfunction of the VGT system 
when proper functional response of the system to computer commands does 
not occur.
    (D) Turbo boost feedback control. See paragraph (i)(6)of this 
section.
    (E) Charge air undercooling. The OBD system must detect a 
malfunction of the charge air cooling system prior to a decrease from 
the manufacturer's specified cooling rate that would cause an engine's 
emissions to exceed the emissions thresholds for ``other monitors'' as 
shown in Table 1 of this paragraph (g). For engines in which no failure 
or deterioration of the charge air cooling system that causes a decrease 
in cooling performance could result in an engine's emissions exceeding 
the applicable emissions thresholds, the OBD system must detect a 
malfunction when the system has no detectable amount of charge air 
cooling.
    (iii) Turbo boost monitoring conditions. (A) The OBD system must 
monitor continuously for malfunctions identified in paragraphs 
(g)(4)(ii)(A), (g)(4)(ii)(B), and (g)(4)(ii)(D) of this section.
    (B) The manufacturer must define the monitoring conditions for 
malfunctions identified in paragraph (g)(4)(ii)(C) of this section in 
accordance with paragraphs (c) and (d) of this section, with the 
exception that monitoring must occur every time the monitoring 
conditions are met during the drive cycle rather than once per drive 
cycle as required in paragraph (c)(2) of this section. For purposes of 
tracking and reporting as required in paragraph (d)(1) of this section, 
all monitors used to detect malfunctions identified in

[[Page 504]]

paragraph (g)(4)(ii)(C) of this section must be tracked separately but 
reported as a single set of values as specified in paragraph (e)(1)(iii) 
of this section.
    (C) The manufacturer must define the monitoring conditions for 
malfunctions identified in paragraph (g)(4)(ii)(E) of this section in 
accordance with paragraphs (c) and (d) of this section. For purposes of 
tracking and reporting as required in paragraph (d)(1) of this section, 
all monitors used to detect malfunctions identified in paragraph 
(g)(4)(ii)(E) of this section must be tracked separately but reported as 
a single set of values as specified in paragraph (e)(1)(iii) of this 
section.
    (D) The manufacturer may request Administrator approval to disable 
temporarily the turbo boost system monitor(s) during specific operating 
conditions (e.g., transients, extreme low or high flow conditions). The 
manufacturer must be able to demonstrate via data or engineering 
analysis that a reliable system monitor cannot be run when these 
conditions exist because it cannot robustly distinguish between a 
malfunctioning system and a properly operating system. The manufacturer 
is still required to maintain comprehensive component monitoring as 
required in paragraph (i)(3) of this section.
    (iv) Turbo boost system MIL activation and DTC storage. The MIL must 
activate and DTCs must be stored according to the provisions of 
paragraph (b) of this section.
    (5) NMHC converting catalyst monitoring--(i) General. The OBD system 
must monitor the NMHC converting catalyst(s) for proper NMHC conversion 
capability. For purposes of this paragraph (g)(5), each catalyst that 
converts NMHC must be monitored either individually or in combination 
with others. For purposes of this paragraph (g)(5), NMHC conversion that 
may occur over the DPF or other aftertreatment devices is not included.
    (ii) NMHC converting catalyst malfunction criteria--(A) NMHC 
converting catalyst conversion efficiency. The OBD system must detect a 
malfunction when the catalyst has no detectable amount of NMHC 
conversion capability.
    (B) NMHC converting catalyst aftertreatment assistance functions. 
For catalysts used to generate an exotherm to assist DPF regeneration, 
the OBD system must detect a malfunction when the catalyst is unable to 
generate a sufficient exotherm to achieve DPF regeneration. In meeting 
this requirement, the OBD system must detect a malfunction when the DOC 
is unable to generate a temperature rise of 100 degrees C, or to reach 
the necessary DPF regeneration temperature, within 60 seconds of 
initiating an active DPF regeneration. Further, the OBD system must 
detect a malfunction when the DOC is unable to sustain the necessary 
regeneration temperature for the duration of the regeneration event. The 
OBD or control system must abort the regeneration if the regeneration 
temperature has not been reached within five minutes of initiating an 
active regeneration event, or if the regeneration temperature cannot be 
sustained for the duration of the regeneration event. As an alternative 
to these specific malfunction criteria, the manufacturer may employ 
different criteria. To do so, the manufacturer must submit a description 
with supporting data, subject to Administrator approval, of their DPF 
regeneration monitoring strategy. The Administrator will consider the 
strategy's equivalence to the specific criteria stated in this paragraph 
when considering the request. Also as an alternative to these specific 
malfunction criteria, the manufacturer may employ an OBD monitor that 
detects a catalyst malfunction when the catalyst conversion capability 
decreases to the point that NMHC emissions exceed 2.5 times the 
applicable NMHC emission standard but must adjust emission test results 
pursuant to paragraph (f)(2) of this section. For catalysts located 
downstream of a DPF and used to convert NMHC emissions during DPF 
regeneration, the OBD system must detect a malfunction when the catalyst 
has no detectable amount of NMHC conversion capability unless the 
manufacturer can demonstrate that deterioration or malfunction of the 
catalyst will not result in emissions that exceed the applicable NMHC 
standard.
    (iii) NMHC converting catalyst monitoring conditions. The 
manufacturer

[[Page 505]]

must define the monitoring conditions for malfunctions identified in 
paragraphs (g)(5)(ii)(A) and (g)(5)(ii)(B) of this section in accordance 
with paragraphs (c) and (d) of this section. For purposes of tracking 
and reporting as required in paragraph (d)(1) of this section, all 
monitors used to detect malfunctions identified in paragraphs 
(g)(5)(ii)(A) and (g)(5)(ii)(B) of this section must be tracked 
separately but reported as a single set of values as specified in 
paragraph (e)(1)(iii) of this section.
    (iv) NMHC converting catalyst MIL activation and DTC storage. The 
MIL must activate and DTCs must be stored according to the provisions of 
paragraph (b) of this section. The monitoring method for the NMHC 
converting catalyst(s) must be capable of detecting all instances, 
except diagnostic self-clearing, when a catalyst DTC has been erased but 
the catalyst has not been replaced (e.g., catalyst over-temperature 
histogram approaches are not acceptable).
    (6) Selective catalytic reduction (SCR) and lean NOX 
catalyst monitoring--(i) General. The OBD system must monitor the SCR 
and/or the lean NOX converting catalyst(s) for proper 
conversion capability. For engines equipped with SCR systems or other 
catalyst systems that use an active/intrusive reductant injection (e.g., 
active lean NOX catalysts that use diesel fuel post-injection 
or in-exhaust injection), the OBD system must monitor the active/
intrusive reductant injection system for proper performance. The 
individual electronic components (e.g., actuators, valves, sensors, 
heaters, pumps) in the active/intrusive reductant injection system must 
be monitored in accordance with the comprehensive component requirements 
in paragraph (i)(3) of this section. For purposes of this paragraph 
(g)(6), each catalyst that converts NOX must be monitored 
either individually or in combination with others.
    (ii) SCR and lean NOX catalyst malfunction criteria--(A) 
SCR and lean NOX catalyst conversion efficiency. The OBD 
system must detect a catalyst malfunction when the catalyst conversion 
capability decreases to the point that would cause an engine's emissions 
to exceed the emissions thresholds for NOX aftertreatment 
systems as shown in Table 1 of this paragraph (g). If no failure or 
deterioration of the catalyst NOX conversion capability could 
result in an engine's emissions exceeding any of the applicable 
emissions thresholds, the OBD system must detect a malfunction when the 
catalyst has no detectable amount of NOX conversion 
capability.
    (B) SCR and lean NOX catalyst active/intrusive reductant 
delivery performance. The OBD system must detect a malfunction prior to 
any failure or deterioration of the system to properly regulate 
reductant delivery (e.g., urea injection, separate injector fuel 
injection, post injection of fuel, air assisted injection/mixing) that 
would cause an engine's emissions to exceed any of the applicable 
emissions thresholds for NOX aftertreatment systems as shown 
in Table 1 of this paragraph (g). If no failure or deterioration of the 
reductant delivery system could result in an engine's emissions 
exceeding any of the applicable thresholds, the OBD system must detect a 
malfunction when the system has reached its control limits such that it 
is no longer able to deliver the desired quantity of reductant.
    (C) SCR and lean NOX catalyst active/intrusive reductant 
quantity. If the SCR or lean NOX catalyst system uses a 
reductant other than the fuel used for the engine, or uses a reservoir/
tank for the reductant that is separate from the fuel tank used for the 
engine, the OBD system must detect a malfunction when there is no longer 
sufficient reductant available (e.g., the reductant tank is empty).
    (D) SCR and lean NOX catalyst active/intrusive reductant 
quality. If the SCR or lean NOX catalyst system uses a 
reservoir/tank for the reductant that is separate from the fuel tank 
used for the engine, the OBD system must detect a malfunction when an 
improper reductant is used in the reductant reservoir/tank (e.g., the 
reductant tank is filled with something other than the reductant).
    (E) SCR and lean NOX catalyst active/intrusive reductant 
feedback control. See paragraph (i)(6) of this section.

[[Page 506]]

    (iii) SCR and lean NOX catalyst monitoring conditions. 
(A) The manufacturers must define the monitoring conditions for 
malfunctions identified in paragraphs (g)(6)(ii)(A) and (g)(6)(ii)(D) of 
this section in accordance with paragraphs (c) and (d) of this section. 
For purposes of tracking and reporting as required in paragraph (d)(1) 
of this section, all monitors used to detect malfunctions identified in 
paragraph (g)(6)(ii)(A) of this section must be tracked separately but 
reported as a single set of values as specified in paragraph (e)(1)(iii) 
of this section.
    (B) The OBD system must monitor continuously for malfunctions 
identified in paragraphs (g)(6)(ii)(B), (g)(6)(ii)(C), and (g)(6)(ii)(E) 
of this section.
    (iv) SCR and lean NOX catalyst MIL activation and DTC 
storage. (A) For malfunctions identified in paragraph (g)(6)(ii)(A) of 
this section, the MIL must activate and DTCs must be stored according to 
the provisions of paragraph (b) of this section.
    (B) For malfunctions identified in paragraphs (g)(6)(ii)(B), 
(g)(6)(ii)(C), and (g)(6)(ii)(D) of this section, the manufacturer may 
delay activating the MIL if the vehicle is equipped with an alternative 
indicator for notifying the vehicle operator of the malfunction. The 
alternative indicator must be of sufficient illumination and be located 
such that it is readily visible to the vehicle operator under all 
lighting conditions. If the vehicle is not equipped with such an 
alternative indicator and the OBD MIL activates, the MIL may be 
immediately deactivated and the corresponding DTC(s) erased once the OBD 
system has verified that the reductant tank has been refilled properly 
and the MIL has not been activated for any other malfunction. The 
Administrator may approve other strategies that provide equivalent 
assurance that a vehicle operator would be promptly notified and that 
corrective action would be taken.
    (C) The monitoring method for the SCR and lean NOX 
catalyst(s) must be capable of detecting all instances, except 
diagnostic self-clearing, when a catalyst DTC(s) has been erased but the 
catalyst has not been replaced (e.g., catalyst over-temperature 
histogram approaches are not acceptable).
    (7) NOX adsorber system monitoring--(i) General. The OBD 
system must monitor the NOX adsorber on engines so-equipped 
for proper performance. For engines equipped with active/intrusive 
injection (e.g., in-exhaust fuel and/or air injection) to achieve 
desorption of the NOX adsorber, the OBD system must monitor 
the active/intrusive injection system for proper performance. The 
individual electronic components (e.g., injectors, valves, sensors) that 
are used in the active/intrusive injection system must be monitored in 
accordance with the comprehensive component requirements in paragraph 
(i)(3) of this section.
    (ii) NOX adsorber system malfunction criteria--(A) 
NOX adsorber system capability. The OBD system must detect a 
NOX adsorber malfunction when its capability (i.e., its 
combined adsorption and conversion capability) decreases to the point 
that would cause an engine's NOX emissions to exceed the 
emissions thresholds for NOX aftertreatment systems as shown 
in Table 1 of this paragraph (g). If no failure or deterioration of the 
NOX adsorber capability could result in an engine's 
NOX emissions exceeding the applicable emissions thresholds, 
the OBD system must detect a malfunction when the system has no 
detectable amount of NOX adsorber capability.
    (B) NOX adsorber system active/intrusive reductant 
delivery performance. For NOX adsorber systems that use 
active/intrusive injection (e.g., in-cylinder post fuel injection, in-
exhaust air-assisted fuel injection) to achieve desorption of the 
NOX adsorber, the OBD system must detect a malfunction if any 
failure or deterioration of the injection system's ability to properly 
regulate injection causes the system to be unable to achieve desorption 
of the NOX adsorber.
    (C) NOX adsorber system feedback control. Malfunction 
criteria for the NOX adsorber and the NOX adsorber 
active/instrusive reductant delivery system are contained in paragraph 
(i)(6) of this section.
    (iii) NOX adsorber system monitoring conditions. (A) The 
manufacturer must define the monitoring conditions for

[[Page 507]]

malfunctions identified in paragraph (g)(7)(ii)(A) of this section in 
accordance with paragraphs (c) and (d) of this section. For purposes of 
tracking and reporting as required in paragraph (d)(1) of this section, 
all monitors used to detect malfunctions identified in paragraph 
(g)(7)(ii)(A) of this section must be tracked separately but reported as 
a single set of values as specified in paragraph (e)(1)(iii) of this 
section.
    (B) The OBD system must monitor continuously for malfunctions 
identified in paragraphs (g)(7)(ii)(B) and (g)(7)(ii)(C) of this 
section.
    (iv) NOX adsorber system MIL activation and DTC storage. 
The MIL must activate and DTCs must be stored according to the 
provisions of paragraph (b) of this section.
    (8) Diesel particulate filter (DPF) system monitoring--(i) General. 
The OBD system must monitor the DPF on engines so-equipped for proper 
performance. For engines equipped with active regeneration systems that 
use an active/intrusive injection (e.g., in-exhaust fuel injection, in-
exhaust fuel/air burner), the OBD system must monitor the active/
intrusive injection system for proper performance. The individual 
electronic components (e.g., injectors, valves, sensors) that are used 
in the active/intrusive injection system must be monitored in accordance 
with the comprehensive component requirements in paragraph (i)(3) of 
this section.
    (ii) DPF system malfunction criteria--(A) DPF filtering performance. 
The OBD system must detect a malfunction prior to a decrease in the PM 
filtering capability of the DPF (e.g., cracking, melting, etc.) that 
would cause an engine's PM emissions to exceed the emissions thresholds 
for DPF systems as shown in Table 1 of this paragraph (g). If no failure 
or deterioration of the PM filtering performance could result in an 
engine's PM emissions exceeding the applicable emissions thresholds, the 
OBD system must detect a malfunction when no detectable amount of PM 
filtering occurs. As an alternative to a threshold monitor, the OBD 
system, on model year 2010 through 2012 engines only, can be designed to 
detect a malfunction based on a detectable decrease in the expected 
pressure drop across the DPF for a period of 5 seconds or more. The 
monitoring area for this alternative is determined using engine speed 
and load points defined in test cycles and procedures for the 
supplemental emissions test (SET) under Sec.86.1360-2007. The 
monitoring area shall include all engine speed and load points greater 
than a region bounded by a line connecting mode numbers 2, 6, 3, and 13 
(i.e. A100, A75, B50, and C50). At engine speeds greater than ``speed 
C'', the monitor shall run whenever engine load is greater than 50%. For 
purposes of this paragraph, the detectable change in pressure drop is 
determined by operating the engine at the B50 engine speed and load 
point (as described in the SET test procedures), observing the pressure 
drop on a clean, nominal DPF, and multiplying the observed pressure drop 
by 0.5 or other factor supported by data and approved by the 
Administrator. The detectable change in pressure drop shall be reported 
in units of kilopascals (kPa). At time of certification, manufacturers 
shall provide the detectable change in pressure drop value along with 
OBD data stream parameters recorded with a clean DPF under the following 
nine engine speed/load operating points of the SET: A50, A75, A100, B50, 
B75, B100, C50, C75, and C100. The OBD data stream pararmeters to be 
reported are described in (k)(4)(ii) of this section and shall include 
the following: Engine speed; calculated load; air flow rate from mass 
air flow sensor (if so equipped); fuel rate; and DPF delta pressure.
    (B) DPF regeneration frequency. The OBD system must detect a 
malfunction when the DPF regeneration frequency increases from (i.e., 
occurs more often than) the manufacturer's specified regeneration 
frequency to a level such that it would cause an engine's NMHC emissions 
to exceed the emissions threshold for DPF systems as shown in Table 1 of 
this paragraph (g). If no such regeneration frequency exists that could 
cause NMHC emissions to exceed the applicable emission threshold, the 
OBD system must detect a malfunction when the DPF regeneration frequency 
exceeds the manufacturer's specified design limits for allowable 
regeneration frequency.

[[Page 508]]

    (C) DPF incomplete regeneration. The OBD system must detect a 
regeneration malfunction when the DPF does not properly regenerate under 
manufacturer-defined conditions where regeneration is designed to occur.
    (D) DPF missing substrate. The OBD system must detect a malfunction 
if either the DPF substrate is completely destroyed, removed, or 
missing, or if the DPF assembly has been replaced with a muffler or 
straight pipe.
    (E) DPF system active/intrusive injection. For DPF systems that use 
active/intrusive injection (e.g., in-cylinder post fuel injection, in-
exhaust air-assisted fuel injection) to achieve regeneration of the DPF, 
the OBD system must detect a malfunction if any failure or deterioration 
of the injection system's ability to properly regulate injection causes 
the system to be unable to achieve regeneration of the DPF.
    (F) DPF regeneration feedback control. See paragraph (i)(6) of this 
section.
    (iii) DPF monitoring conditions. The manufacturer must define the 
monitoring conditions for malfunctions identified in paragraph 
(g)(8)(ii) of this section in accordance with paragraphs (c) and (d) of 
this section, with the exception that monitoring must occur every time 
the monitoring conditions are met during the drive cycle rather than 
once per drive cycle as required in paragraph (c)(2) of this section. 
For OBD systems designed to the alternative malfunction criteria of 
paragraph (g)(8)(ii)(A) of this section, the alternative DPF monitor 
shall run continuously whenever engine speed and load conditions are 
within the monitoring area described in paragraph (g)(8)(ii)(A). The OBD 
system may make a malfunction or potential malfunction determination 
during any successful monitoring event but shall include in the enable 
criteria of any subsequent monitoring events a confirmed successful and 
complete DPF regeneration. The subsequent monitoring events must be 
conducted within an operating period that ensures that the detected 
malfunction has not ``healed'' due to trapped particulates in the 
compromised portion of the DPF substrate. For purposes of tracking and 
reporting as required in paragraph (d)(1) of this section, all monitors 
used to detect malfunctions identified in paragraph (g)(8)(ii) of this 
section must be tracked separately but reported as a single set of 
values as specified in paragraph (e)(1)(iii) of this section.
    (iv) DPF system MIL activation and DTC storage. The MIL must 
activate and DTCs must be stored according to the provisions of 
paragraph (b) of this section.
    (9) Exhaust gas sensor and sensor heater monitoring--(i) General. 
The OBD system must monitor for proper output signal, activity, response 
rate, and any other parameter that can affect emissions, all exhaust gas 
sensors (e.g., oxygen, air-fuel ratio, NOX) used for emission 
control system feedback (e.g., EGR control/feedback, SCR control/
feedback, NOX adsorber control/feedback) and/or as a 
monitoring device. For engines equipped with heated exhaust gas sensors, 
the OBD system must monitor the heater for proper performance.
    (ii) Malfunction criteria for air-fuel ratio sensors located 
upstream of aftertreatment devices--(A)Sensor performance. The OBD 
system must detect a malfunction prior to any failure or deterioration 
of the sensor voltage, resistance, impedance, current, response rate, 
amplitude, offset, or other characteristic(s) that would cause an 
engine's emissions to exceed the emissions thresholds for ``other 
monitors'' as shown in Table 1 of this paragraph (g).
    (B) Circuit integrity. The OBD system must detect malfunctions of 
the sensor related to a lack of circuit continuity or signal out-of-
range values.
    (C) Feedback function. The OBD system must detect a malfunction of 
the sensor if the emission control system (e.g., EGR, SCR, or 
NOX adsorber) is unable to use that sensor as a feedback 
input (e.g., causes limp-home or open-loop operation).
    (D) Monitoring function. To the extent feasible, the OBD system must 
detect a malfunction of the sensor when the sensor output voltage, 
resistance, impedance, current, amplitude, activity, offset, or other 
characteristics are no

[[Page 509]]

longer sufficient for use as an OBD system monitoring device (e.g., for 
catalyst, EGR, SCR, or NOX adsorber monitoring).
    (iii) Malfunction criteria for air-fuel ratio sensors located 
downstream of aftertreatment devices--(A) Sensor performance. The OBD 
system must detect a malfunction prior to any failure or deterioration 
of the sensor voltage, resistance, impedance, current, response rate, 
amplitude, offset, or other characteristic(s) that would cause an 
engine's emissions to exceed the emissions thresholds for air-fuel ratio 
sensors downstream of aftertreatment devices as shown in Table 1 of this 
paragraph (g).
    (B) Circuit integrity. The OBD system must detect malfunctions of 
the sensor related to a lack of circuit continuity or signal out-of-
range values.
    (C) Feedback function. The OBD system must detect a malfunction of 
the sensor if the emission control system (e.g., EGR, SCR, or 
NOX absorber) is unable to use that sensor as a feedback 
input (e.g., causes limp-home or open-loop operation).
    (D) Monitoring function. To the extent feasible, the OBD system must 
detect a malfunction of the sensor when the sensor output voltage, 
resistance, impedance, current, amplitude, activity, offset, or other 
characteristics are no longer sufficient for use as an OBD system 
monitoring device (e.g., for catalyst, EGR, SCR, or NOX 
absorber monitoring).
    (iv) Malfunction criteria for NOX sensors--(A) Sensor 
performance. The OBD system must detect a malfunction prior to any 
failure or deterioration of the sensor voltage, resistance, impedance, 
current, response rate, amplitude, offset, or other characteristic(s) 
that would cause an engine's emissions to exceed the emissions 
thresholds for NOX sensors as shown in Table 1 of this 
paragraph (g).
    (B) Circuit integrity. The OBD system must detect malfunctions of 
the sensor related to a lack of circuit continuity or signal out-of-
range values.
    (C) Feedback function. The OBD system must detect a malfunction of 
the sensor if the emission control system (e.g., EGR, SCR, or 
NOX adsorber) is unable to use that sensor as a feedback 
input (e.g., causes limp-home or open-loop operation).
    (D) Monitoring function. To the extent feasible, the OBD system must 
detect a malfunction of the sensor when the sensor output voltage, 
resistance, impedance, current, amplitude, activity, offset, or other 
characteristics are no longer sufficient for use as an OBD system 
monitoring device (e.g., for catalyst, EGR, SCR, or NOX 
adsorber monitoring).
    (v) Malfunction criteria for other exhaust gas sensors. For other 
exhaust gas sensors, the manufacturer must submit a monitoring plan to 
the Administrator for approval. The plan must include data and/or 
engineering evaluations that demonstrate that the monitoring plan is as 
reliable and effective as the monitoring required in paragraphs 
(g)(9)(ii), (g)(9)(iii), (g)(9)(iv) of this section.
    (vi) Malfunction criteria for exhaust gas sensor heaters. (A) The 
OBD system must detect a malfunction of the heater performance when the 
current or voltage drop in the heater circuit is no longer within the 
manufacturer's specified limits for normal operation (i.e., within the 
criteria required to be met by the component vendor for heater circuit 
performance at high mileage). The manufacturer may use other malfunction 
criteria for heater performance malfunctions. To do so, the manufacturer 
must be able to demonstrate via data and/or an engineering evaluation 
that the monitor is reliable and robust.
    (B) The OBD system must detect malfunctions of the heater circuit 
including open or short circuits that conflict with the commanded state 
of the heater (e.g., shorted to 12 Volts when commanded to 0 Volts 
(ground)).
    (vii) Monitoring conditions for exhaust gas sensors. (A) The 
manufacturer must define the monitoring conditions for malfunctions 
identified in paragraphs (g)(9)(ii)(A), (g)(9)(iii)(A), and 
(g)(9)(iv)(A) of this section (i.e., sensor performance) in accordance 
with paragraphs (c) and (d) of this section. For purposes of tracking 
and reporting as required in paragraph (d)(1) of this section, all 
monitors used to detect malfunctions identified in paragraphs 
(g)(9)(ii)(A), (g)(9)(iii)(A), and

[[Page 510]]

(g)(9)(iv)(A) of this section must be tracked separately but reported as 
a single set of values as specified in paragraph (e)(1)(iii) of this 
section.
    (B) The manufacturer must define the monitoring conditions for 
malfunctions identified in paragraphs (g)(9)(ii)(D), (g)(9)(iii)(D), and 
(g)(9)(iv)(D) of this section (i.e., monitoring function) in accordance 
with paragraphs (c) and (d) of this section with the exception that 
monitoring must occur every time the monitoring conditions are met 
during the drive cycle rather than once per drive cycle as required in 
paragraph (c)(2) of this section.
    (C) Except as provided for in paragraph (g)(9)(vii)(D) of this 
section, the OBD system must monitor continuously for malfunctions 
identified in paragraphs (g)(9)(ii)(B), (g)(9)(ii)(C), (g)(9)(iii)(B), 
(g)(9)(iii)(C), (g)(9)(iv)(B), (g)(9)(iv)(C) of this section (i.e., 
circuit integrity and feedback function).
    (D) A manufacturer may request approval to disable continuous 
exhaust gas sensor monitoring when an exhaust gas sensor malfunction 
cannot be distinguished from other effects (e.g., disable monitoring for 
out-of-range on the low side during fuel cut conditions). To do so, the 
manufacturer must demonstrate via data and/or engineering analyses that 
a properly functioning sensor cannot be distinguished from a 
malfunctioning sensor and that the disablement interval is limited only 
to that necessary for avoiding falsemalfunction detection.
    (viii) Monitoring conditions for exhaust gas sensor heaters--(A) The 
manufacturer must define monitoring conditions for malfunctions 
identified in paragraph (g)(9)(vi)(A) of this section (i.e., sensor 
heater performance) in accordance with paragraphs (c) and (d) of this 
section.
    (B) The OBD system must monitor continuously for malfunctions 
identified in paragraph (g)(9)(vi)(B) of this section (i.e., circuit 
malfunctions).
    (ix) Exhaust gas sensor and sensor heater MIL activation and DTC 
storage. The MIL must activate and DTCs must be stored according to the 
provisions of paragraph (b) of this section.
    (10) Variable Valve Timing (VVT) system monitoring--(i) General. The 
OBD system must monitor the VVT system on engines so equipped for target 
error and slow response malfunctions. The individual electronic 
components (e.g., actuators, valves, sensors) that are used in the VVT 
system must be monitored in accordance with the comprehensive components 
requirements in paragraph (i)(3) of this section.
    (ii) VVT system malfunction criteria--(A) VVT system target error. 
The OBD system must detect a malfunction prior to any failure or 
deterioration in the capability of the VVT system to achieve the 
commanded valve timing and/or control within a crank angle and/or lift 
tolerance that would cause an engine's emissions to exceed the emission 
thresholds for ``other monitors'' as shown in Table 1 of this paragraph 
(g).
    (B) VVT slow response. The OBD system must detect a malfunction 
prior to any failure or deterioration in the capability of the VVT 
system to achieve the commanded valve timing and/or control within a 
manufacturer-specified time that would cause an engine's emissions to 
exceed the emission thresholds for ``other monitors'' as shown in Table 
1 of this paragraph (g).
    (C) For engines in which no failure or deterioration of the VVT 
system could result in an engine's emissions exceeding the applicable 
emissions thresholds of paragraphs (g)(10)(ii)(A) and (g)(10)(ii)(B) of 
this section, the OBD system must detect a malfunction of the VVT system 
when proper functional response of the system to computer commands does 
not occur.
    (iii) VVT system monitoring conditions. Manufacturers must define 
the monitoring conditions for VVT system malfunctions identified in 
paragraph (g)(10)(ii) of this section in accordance with paragraphs (c) 
and (d) of this section, with the exception that monitoring must occur 
every time the monitoring conditions are met during the drive cycle 
rather than once per drive cycle as required in paragraph (c)(2) of this 
section. For purposes of tracking and reporting as required in paragraph 
(d)(1) of this section, all monitors used to detect malfunctions 
identified in paragraph (g)(10)(ii) of this section

[[Page 511]]

must be tracked separately but reported as a single set of values as 
specified in paragraph (e)(1)(iii) of this section.
    (iv) VVT MIL activation and DTC storage. The MIL must activate and 
DTCs must be stored according to the provisions of paragraph (b) of this 
section.
    (h) OBD monitoring requirements for gasoline-fueled/spark-ignition 
engines. The following table shows the thresholds at which point certain 
components or systems, as specified in this paragraph (h), are 
considered malfunctioning.

----------------------------------------------------------------------------------------------------------------
Notes: 1.75x std means a multiple of 1.75 times the applicable emissions standard; these emissions thresholds
  apply to the monitoring requirements of paragraph (h) of this section; The evaporative emissions control
  system threshold is not, technically, an emissions threshold but rather a leak size that must be detected;
  nonetheless, for ease we refer to this as the threshold.

    (1) Fuel system monitoring--(i) General. The OBD system must monitor 
the fuel delivery system to determine its ability to provide compliance 
with emission standards.
    (ii) Fuel system malfunction criteria. (A) The OBD system must 
detect a malfunction of the fuel delivery system (including feedback 
control based on a secondary oxygen sensor) when the fuel delivery 
system is unable to maintain an engine's emissions at or below the 
emissions thresholds for ``other monitors'' as shown in Table 2 of this 
paragraph (h).
    (B) Except as provided for in paragraph (h)(1)(ii)(C) of this 
section, if the engine is equipped with adaptive feedback control, the 
OBD system must detect a malfunction when the adaptive feedback control 
has used up all of the adjustment allowed by the manufacturer.
    (C) If the engine is equipped with feedback control that is based on 
a secondary oxygen (or equivalent) sensor, the OBD system is not 
required to detect a malfunction of the fuel system solely when the 
feedback control based on a secondary oxygen sensor has used up all of 
the adjustment allowed by the manufacturer. However, if a failure or 
deterioration results in engine emissions that exceed the emissions 
thresholds for ``other monitors'' as shown in Table 2 of this paragraph 
(h), the OBD system is required to detect a malfunction.
    (D) The OBD system must detect a malfunction whenever the fuel 
control system fails to enter closed loop operation following engine 
start within a manufacturer specified time interval. The specified time 
interval must be supported by data and/or engineering analyses submitted 
by the manufacturer.
    (E) The manufacturer may adjust the malfunction criteria and/or 
monitoring conditions to compensate for changes in altitude, for 
temporary introduction of large amounts of purge vapor, or for other 
similar identifiable operating conditions when such conditions occur.
    (iii) Fuel system monitoring conditions. The fuel system must be 
monitored continuously for the presence of a malfunction.
    (iv) Fuel system MIL activation and DTC storage. (A) A pending DTC 
must be stored immediately upon the fuel system exceeding the 
malfunction criteria established in paragraph (h)(1)(ii) of this 
section.
    (B) Except as provided for in paragraph (h)(1)(iv)(C) of this 
section, if a pending DTC is stored, the OBD system must activate the 
MIL immediately and store a MIL-on DTC if a malfunction is again 
detected during either the drive cycle immediately following storage of 
the pending DTC regardless of

[[Page 512]]

the conditions encountered during that drive cycle, or on the next drive 
cycle in which similar conditions are encountered to those that occurred 
when the pending DTC was stored. Similar conditions means engine 
conditions having an engine speed within 375 rpm, load conditions within 
20 percent, and the same warm-up status (i.e., cold or hot) as the 
engine conditions stored pursuant to paragraph (h)(1)(iv)(E) of this 
section. Other definitions of similar conditions may be used but must 
result in comparable timeliness and reliability in detecting similar 
engine operation.
    (C) The pending DTC may be erased at the end of the next drive cycle 
in which similar conditions have been encountered without having again 
exceeded the specified fuel system malfunction criteria. The pending DTC 
may also be erased if similar conditions are not encountered during the 
80 drive cycles immediately following detection of the potential 
malfunction for which the pending DTC was stored.
    (D) Storage of freeze frame conditions. The OBD system must store 
and erase freeze frame conditions either in conjunction with storing and 
erasing a pending DTC or in conjunction with storing and erasing a MIL-
on DTC. Freeze frame information associated with a fuel system 
malfunction shall be stored in preference to freeze frame information 
required elsewhere in paragraphs (h) or (i) of this section.
    (E) Storage of fuel system conditions for determining similar 
conditions of operation. The OBD must store the engine speed, load, and 
warm-up status present at the time it first detects a potential 
malfunction meeting the criteria of paragraph (h)(1)(ii) of this section 
and stores a pending DTC.
    (F) Deactivating the MIL. The MIL may be extinguished after three 
sequential driving cycles in which similar conditions have been 
encountered without detecting a malfunction of the fuel system.
    (2) Engine misfire monitoring--(i) General. (A) The OBD system must 
monitor the engine for misfire causing catalyst damage and misfire 
causing excess emissions.
    (B) The OBD system must identify the specific cylinder that is 
misfiring. The manufacturer may store a general misfire DTC instead of a 
cylinder specific DTC under certain operating conditions. To do so, the 
manufacturer must submit data and/or engineering analyses that 
demonstrate that the misfiring cylinder cannot be identified reliably 
when the conditions occur.
    (C) If more than one cylinder is misfiring, a separate DTC must be 
stored to indicate that multiple cylinders are misfiring unless 
otherwise allowed by this paragraph (h)(2). When identifying multiple 
cylinder misfire, the OBD system is not required to also identify using 
separate DTCs each of the misfiring cylinders individually. If more than 
90 percent of the detected misfires occur in a single cylinder, an 
appropriate DTC may be stored that indicates the specific misfiring 
cylinder rather than storing the multiple cylinder misfire DTC. If two 
or more cylinders individually have more than 10 percent of the total 
number of detected misfires, a multiple cylinder DTC must be stored.
    (ii) Engine misfire malfunction criteria--(A) Misfire causing 
catalyst damage. The manufacturer must determine the percentage of 
misfire evaluated in 200 revolution increments for each engine speed and 
load condition that would result in a temperature that causes catalyst 
damage. If this percentage of misfire is exceeded, it shall be 
considered a malfunction that must be detected. For every engine speed 
and load condition for which this percentage of misfire is determined to 
be lower than five percent, the manufacturer may set the malfunction 
criteria at five percent. The manufacturer may use a longer interval 
than 200 revolutions but only for determining, on a given drive cycle, 
the first misfire exceedance as provided in paragraph (h)(2)(iv)(A) of 
this section. To do so, the manufacturer must demonstrate that the 
interval is not so long that catalyst damage would occur prior to the 
interval being elapsed.
    (B) Misfire causing emissions to exceed the applicable thresholds. 
The manufacturer must determine the percentage of misfire evaluated in 
1000 revolution increments that would cause emissions

[[Page 513]]

from an emissions durability demonstration engine to exceed the 
emissions thresholds for ``other monitors'' as shown in Table 2 of this 
paragraph (h) if that percentage of misfire were present from the 
beginning of the test. If this percentage of misfire is exceeded, 
regardless of the pattern of misfire events (e.g., random, equally 
spaced, continuous), it shall be considered a malfunction that must be 
detected. To establish this percentage of misfire, the manufacturer must 
use misfire events occurring at equally spaced, complete engine cycle 
intervals, across randomly selected cylinders throughout each 1000-
revolution increment. If this percentage of misfire is determined to be 
lower than one percent, the manufacturer may set the malfunction 
criteria at one percent. The manufacturer may use a longer interval than 
1000 revolutions. To do so, the manufacturer must demonstrate that the 
strategy would be equally effective and timely at detecting misfire.
    (iii) Engine misfire monitoring conditions. (A) The OBD system must 
monitor continuously for misfire under the following conditions: from no 
later than the end of the second crankshaft revolution after engine 
start; during the rise time and settling time for engine speed to reach 
the desired idle engine speed at engine start-up (i.e., ``flare-up'' and 
``flare-down''); and, under all positive torque engine speeds and load 
conditions except within the engine operating region bound by the 
positive torque line (i.e., engine load with the transmission in 
neutral), and the points represented by an engine speed of 3000 rpm with 
the engine load at the positive torque line and the redline engine speed 
with the engine's manifold vacuum at four inches of mercury lower than 
that at the positive torque line. For this purpose, redline engine speed 
is defined as either the recommended maximum engine speed as displayed 
on the instrument panel tachometer, or the engine speed at which fuel 
shutoff occurs.
    (B) If an OBD monitor cannot detect all misfire patterns under all 
required engine speed and load conditions as required by paragraph 
(h)(2)(iii)(A) of this section, the OBD system may still be acceptable. 
The Administrator will evaluate the following factors in making a 
determination: The magnitude of the region(s) in which misfire detection 
is limited; the degree to which misfire detection is limited in the 
region(s) (i.e., the probability of detection of misfire events); the 
frequency with which said region(s) are expected to be encountered in-
use; the type of misfire patterns for which misfire detection is 
troublesome; and demonstration that the monitoring technology employed 
is not inherently incapable of detecting misfire under the required 
conditions (i.e., compliance can be achieved on other engines). The 
evaluation will be based on the following misfire patterns: equally 
spaced misfire occurring on randomly selected cylinders; single cylinder 
continuous misfire; and paired cylinder (cylinders firing at the same 
crank angle) continuous misfire.
    (C) The manufacturer may use monitoring system that has reduced 
misfire detection capability during the portion of the first 1000 
revolutions after engine start that a cold start emission reduction 
strategy is active that reduces engine torque (e.g., spark retard 
strategies). To do so, the manufacturer must demonstrate that the 
probability of detection is greater than or equal to 75 percent during 
the worst case condition (i.e., lowest generated torque) for a vehicle 
operated continuously at idle (park/neutral idle) on a cold start 
between 50 and 86 degrees Fahrenheit and that the technology cannot 
reliably detect a higher percentage of the misfire events during the 
conditions.
    (D) The manufacturer may disable misfire monitoring or use an 
alternative malfunction criterion when misfire cannot be distinguished 
from other effects. To do so, the manufacturer must demonstrate that the 
disablement interval or the period of use of an alternative malfunction 
criterion is limited only to that necessary for avoiding false detection 
and for one or more of the following operating conditions: Rough road; 
fuel cut; gear changes for manual transmission vehicles; traction 
control or other vehicle stability control activation such as anti-lock 
braking or other engine torque modifications to enhance vehicle 
stability; off-board control or intrusive activation of vehicle 
components

[[Page 514]]

or monitors during service or assembly plant testing; portions of 
intrusive evaporative system or EGR monitors that can significantly 
affect engine stability (i.e., while the purge valve is open during the 
vacuum pull-down of an evaporative system leak check but not while the 
purge valve is closed and the evaporative system is sealed or while an 
EGR monitor causes the EGR valve to be cycled intrusively on and off 
during positive torque conditions); or, engine speed, load, or torque 
transients due to throttle movements more rapid than those that occur 
over the FTP cycle for the worst case engine within each engine family. 
In general, the Administrator will not approve disablement for 
conditions involving normal air conditioning compressor cycling from on-
to-off or off-to-on, automatic transmission gear shifts (except for 
shifts occurring during wide open throttle operation), transitions from 
idle to off-idle, normal engine speed or load changes that occur during 
the engine speed rise time and settling time (i.e., ``flare-up'' and 
``flare-down'') immediately after engine starting without any vehicle 
operator-induced actions (e.g., throttle stabs), or excess acceleration 
(except for acceleration rates that exceed the maximum acceleration rate 
obtainable at wide open throttle while the vehicle is in gear due to 
abnormal conditions such as slipping of a clutch). The Administrator may 
approve misfire monitoring disablement or use of an alternate 
malfunction criterion for any other condition on a case by case basis 
upon determining that the manufacturer has demonstrated that the request 
is based on an unusual or unforeseen circumstance and that it is 
applying the best available computer and monitoring technology.
    (E) For engines with more than eight cylinders that cannot meet the 
requirements of paragraph (h)(2)(iii)(A) of this section, a manufacturer 
may use alternative misfire monitoring conditions. Such use must be 
based on data and/or an engineering evaluation submitted by the 
manufacturer that demonstrate that misfire detection throughout the 
required operating region cannot be achieved when employing proven 
monitoring technology (i.e., a technology that provides for compliance 
with these requirements on other engines) and provided misfire is 
detected to the fullest extent permitted by the technology. However, the 
misfire detection system must still monitor during all positive torque 
operating conditions encountered during an FTP cycle.
    (iv) MIL activation and DTC storage for engine misfire causing 
catalyst damage--(A) Pending DTCs. A pending DTC must be stored 
immediately if, during a single drive cycle, the specified misfire 
percentage described in paragraph (h)(2)(ii)(A) of this section is 
exceeded three times when operating in the positive torque region 
encountered during a FTP cycle or is exceeded on a single occasion when 
operating at any other engine speed and load condition in the positive 
torque region defined in paragraph (h)(2)(iii)(A) of this section. 
Immediately after a pending DTC is stored pursuant to this paragraph, 
the MIL must blink once per second at all times during the drive cycle 
that engine misfire is occurring. The MIL may be deactivated during 
those times that misfire is not occurring. If, at the time that a 
catalyst damaging misfire malfunction occurs, the MIL is already 
activated for a malfunction other than misfire, the MIL must still blink 
once per second at all times during the drive cycle that engine misfire 
is occurring. If misfire ceases, the MIL must stop blinking but remain 
activated as appropriate in accordance with the other malfunction.
    (B) MIL-on DTCs. If a pending DTC is stored in accordance with 
paragraph (h)(2)(iv)(A) of this section, the OBD system must immediately 
store a MIL-on DTC if the percentage of misfire described in paragraph 
(h)(2)(ii)(A) of this section is again exceeded one or more times during 
either the drive cycle immediately following storage of the pending DTC, 
regardless of the conditions encountered during that drive cycle, or on 
the next drive cycle in which similar conditions are encountered to 
those that occurred when the pending DTC was stored. If, during a 
previous drive cycle, a pending DTC is stored in accordance with 
paragraph (h)(2)(iv)(A) of this section, a MIL-on DTC must be stored 
immediately upon

[[Page 515]]

exceeding the percentage misfire described in paragraph (h)(2)(ii)(A) of 
this section regardless of the conditions encountered. Upon storage of a 
MIL-on DTC, the MIL must blink once per second at all times during the 
drive cycle that engine misfire is occurring. If misfire ceases, the MIL 
must stop blinking but remain activated until the conditions are met for 
extinguishing the MIL.
    (C) Erasure of pending DTCs. Pending DTCs stored in accordance with 
paragraph (h)(2)(iv)(A) of this section must be erased at the end of the 
next drive cycle in which similar conditions are encountered to those 
that occurred when the pending DTC was stored provided no exceedances 
have been detected of the misfire percentage described in paragraph 
(h)(2)(ii)(A) of this section. The pending DTC may also be erased if 
similar conditions are not encountered during the next 80 drive cycles 
immediately following storage of the pending DTC.
    (D) Exemptions for engines with fuel shutoff and default fuel 
control. In engines that provide for fuel shutoff and default fuel 
control to prevent over fueling during catalyst damaging misfire 
conditions, the MIL need not blink as required by paragraphs 
(h)(2)(iv)(A) and (h)(2)(iv)(B) of this section. Instead, the MIL may be 
activated continuously upon misfire detection provided that the fuel 
shutoff and default fuel control are activated immediately upon misfire 
detection. Fuel shutoff and default fuel control may be deactivated only 
when the engine is outside of the misfire range except that the 
manufacturer may periodically, but not more than once every 30 seconds, 
deactivate fuel shutoff and default fuel control to determine if the 
catalyst damaging misfire is still occurring. Normal fueling and fuel 
control may be resumed if the catalyst damaging misfire is no longer 
occurring.
    (E) The manufacturer may use a strategy that activates the MIL 
continuously rather than blinking the MIL during extreme catalyst damage 
misfire conditions (i.e., catalyst damage misfire occurring at all 
engine speeds and loads). Use of such a strategy must be limited to 
catalyst damage misfire levels that cannot be avoided during reasonable 
driving conditions. To use such a strategy, the manufacturer must be 
able to demonstrate that the strategy will encourage operation of the 
vehicle in conditions that will minimize catalyst damage (e.g., at low 
engine speeds and loads).
    (v) MIL activation and DTC storage for engine misfire causing 
emissions to exceed applicable emissions thresholds. (A) Immediately 
upon detection, during the first 1000 revolutions after engine start of 
the misfire percentage described in paragraph (h)(2)(ii)(B) of this 
section, a pending DTC must be stored. If such a pending DTC is stored 
already and another such exceedance of the misfire percentage is 
detected within the first 1000 revolutions after engine start on any 
subsequent drive cycle, the MIL must activate and a MIL-on DTC must be 
stored. The pending DTC may be erased if, at the end of the next drive 
cycle in which similar conditions are encountered to those that occurred 
when the pending DTC was stored, there has been no exceedance of the 
misfire percentage described in paragraph (h)(2)(ii)(B) of this section. 
The pending DTC may also be erased if similar conditions are not 
encountered during the next 80 drive cycles immediately following 
storage of the pending DTC.
    (B) No later than the fourth detection during a single drive cycle, 
following the first 1000 revolutions after engine start of the misfire 
percentage described in paragraph (h)(2)(ii)(B) of this section, a 
pending DTC must be stored. If such a pending DTC is stored already, 
then the MIL must activate and a MIL-on DTC must be stored within 10 
seconds of the fourth detection of the misfire percentage described in 
paragraph (h)(2)(ii)(B) of this section during either the drive cycle 
immediately following storage of the pending DTC, regardless of the 
conditions encountered during that drive cycle excepting those 
conditions within the first 1000 revolutions after engine start, or on 
the next drive cycle in which similar conditions are encountered to 
those that occurred when the pending DTC was stored excepting those 
conditions within the first 1000 revolutions after engine start. The 
pending DTC may be erased if, at the

[[Page 516]]

end of the next drive cycle in which similar conditions are encountered 
to those that occurred when the pending DTC was stored, there has been 
no exceedance of the misfire percentage described in paragraph 
(h)(2)(ii)(B) of this section. The pending DTC may also be erased if 
similar conditions are not encountered during the next 80 drive cycles 
immediately following storage of the pending DTC.
    (vi) Storage of freeze frame conditions for engine misfire. (A) The 
OBD system must store and erase freeze frame conditions (as defined in 
paragraph (k)(4)(iii) of this section) either in conjunction with 
storing and erasing a pending DTC or in conjunction with storing and 
erasing a MIL-on DTC.
    (B) If, upon storage of a DTC as required by paragraphs (h)(2)(iv) 
and (h)(2)(v) of this section, there already exist stored freeze frame 
conditions for a malfunction other than a misfire or fuel system 
malfunction (see paragraph (h)(1) of this section) then the stored 
freeze frame information shall be replaced with freeze frame information 
associated with the misfire malfunction.
    (vii) Storage of engine conditions in association with engine 
misfire. Upon detection of the misfire percentages described in 
paragraphs (h)(2)(ii)(A) and (h)(2)(ii)(B) of this section, the 
following engine conditions must be stored for use in determining 
similar conditions: Engine speed, load, and warm up status of the first 
misfire event that resulted in pending DTC storage.
    (viii) MIL deactivation in association with engine misfire. The MIL 
may be deactivated after three sequential drive cycles in which similar 
conditions have been encountered without an exceedance of the misfire 
percentages described in paragraphs (h)(2)(ii)(A) and (h)(2)(ii)(B) of 
this section.
    (3) Exhaust gas recirculation system monitoring--(i) General. The 
OBD system must monitor the EGR system on engines so equipped for low 
and high flow rate malfunctions. The individual electronic components 
(e.g., actuators, valves, sensors) that are used in the EGR system must 
be monitored in accordance with the comprehensive component requirements 
in paragraph (i)(3) of this section.
    (ii) EGR system malfunction criteria. (A) The OBD system must detect 
a malfunction of the EGR system prior to a decrease from the 
manufacturer's specified EGR flow rate that would cause an engine's 
emissions to exceed the emissions thresholds for ``other monitors'' as 
shown in Table 2 of this paragraph (h). For engines in which no failure 
or deterioration of the EGR system that causes a decrease in flow could 
result in an engine's emissions exceeding the applicable emissions 
thresholds, the OBD system must detect a malfunction when the system has 
no detectable amount of EGR flow.
    (B) The OBD system must detect a malfunction of the EGR system prior 
to an increase from the manufacturer's specified EGR flow rate that 
would cause an engine's emissions to exceed the emissions thresholds for 
``other monitors'' as shown in Table 2 of this paragraph (h). For 
engines in which no failure or deterioration of the EGR system that 
causes an increase in flow could result in an engine's emissions 
exceeding the applicable emissions thresholds, the OBD system must 
detect a malfunction when the system has reached its control limits such 
that it cannot reduce EGR flow.
    (iii) EGR system monitoring conditions. (A) The manufacturer must 
define the monitoring conditions for malfunctions identified in 
paragraph (h)(3)(ii) of this section in accordance with paragraphs (c) 
and (d) of this section. For purposes of tracking and reporting as 
required by paragraph (d)(1) of this section, all monitors used to 
detect malfunctions identified in paragraph (h)(3)(ii) of this section 
must be tracked separately but reported as a single set of values as 
specified in paragraph (e)(1)(iii) of this section.
    (B) The manufacturer may disable temporarily the EGR monitor under 
conditions when monitoring may not be reliable (e.g., when freezing may 
affect performance of the system). To do so, the manufacturer must be 
able to demonstrate that the monitor is unreliable when such conditions 
exist.
    (iv) EGR system MIL activation and DTC storage. The MIL must 
activate and DTCs must be stored according to

[[Page 517]]

the provisions of paragraph (b) of this section.
    (4) Cold start emission reduction strategy monitoring--(i) General. 
If an engine incorporates a specific engine control strategy to reduce 
cold start emissions, the OBD system must monitor the key components 
(e.g., idle air control valve), other than secondary air, while the 
control strategy is active to ensure proper operation of the control 
strategy.
    (ii) Cold start strategy malfunction criteria. (A) The OBD system 
must detect a malfunction prior to any failure or deterioration of the 
individual components associated with the cold start emission reduction 
control strategy that would cause an engine's emissions to exceed the 
emissions thresholds for ``other monitors'' as shown in Table 2 of this 
paragraph (h). The manufacturer must establish the malfunction criteria 
based on data from one or more representative engine(s) and provide an 
engineering evaluation for establishing the malfunction criteria for the 
remainder of the manufacturer's product line.
    (B) Where no failure or deterioration of a component used for the 
cold start emission reduction strategy could result in an engine's 
emissions exceeding the applicable emissions thresholds, the individual 
component must be monitored for proper functional response while the 
control strategy is active in accordance with the malfunction criteria 
in paragraphs (i)(3)(ii) and (i)(3)(iii) of this section.
    (iii) Cold start strategy monitoring conditions. The manufacturer 
must define monitoring conditions for malfunctions identified in 
paragraph (h)(4)(ii) of this section in accordance with paragraphs (c) 
and (d) of this section.
    (iv) Cold start strategy MIL activation and DTC storage. The MIL 
must activate and DTCs must be stored according to the provisions of 
paragraph (b) of this section.
    (5) Secondary air system monitoring--(i) General. The OBD system on 
engines equipped with any form of secondary air delivery system must 
monitor the proper functioning of the secondary air delivery system 
including all air switching valve(s). The individual electronic 
components (e.g., actuators, valves, sensors) that are used in the 
secondary air system must be monitored in accordance with the 
comprehensive component requirements in paragraph (i)(3) of this 
section. For purposes of this paragraph (h)(5), ``air flow'' is defined 
as the air flow delivered by the secondary air system to the exhaust 
system. For engines using secondary air systems with multiple air flow 
paths/distribution points, the air flow to each bank (i.e., a group of 
cylinders that share a common exhaust manifold, catalyst, and control 
sensor) must be monitored in accordance with the malfunction criteria in 
paragraph (h)(5)(ii) of this section. Also for purposes of this 
paragraph (h)(5), ``normal operation'' is defined as the condition when 
the secondary air system is activated during catalyst and/or engine 
warm-up following engine start. ``Normal operation'' does not include 
the condition when the secondary air system is turned on intrusively for 
the sole purpose of monitoring.
    (ii) Secondary air system malfunction criteria. (A) Except as 
provided in paragraph (h)(5)(ii)(C) of this section, the OBD system must 
detect a secondary air system malfunction prior to a decrease from the 
manufacturer's specified air flow during normal operation that would 
cause an engine's emissions to exceed the emissions thresholds for 
``other monitors'' as shown in Table 2 of this paragraph (h).
    (B) Except as provided in paragraph (h)(5)(ii)(C) of this section, 
the OBD system must detect a secondary air system malfunction prior to 
an increase from the manufacturer's specified air flow during normal 
operation that would cause an engine's emissions to exceed the emissions 
thresholds for ``other monitors'' as shown in Table 2 of this paragraph 
(h).
    (C) For engines in which no deterioration or failure of the 
secondary air system would result in an engine's emissions exceeding the 
applicable emissions thresholds, the OBD system must detect a 
malfunction when no detectable amount of air flow is delivered by the 
secondary air system during normal operation.

[[Page 518]]

    (iii) Secondary air system monitoring conditions. The manufacturer 
must define monitoring conditions for malfunctions identified in 
paragraph (h)(5)(ii) of this section in accordance with paragraphs (c) 
and (d) of this section. For purposes of tracking and reporting as 
required by paragraph (d)(1) of this section, all monitors used to 
detect malfunctions identified in paragraph (h)(5)(ii) of this section 
must be tracked separately but reported as a single set of values as 
specified in paragraph (e)(1)(iii) of this section.
    (iv) Secondary air system MIL activation and DTC storage. The MIL 
must activate and DTCs must be stored according to the provisions of 
paragraph (b) of this section.
    (6) Catalyst system monitoring--(i) General. The OBD system must 
monitor the catalyst system for proper conversion capability.
    (ii) Catalyst system malfunction criteria. The OBD system must 
detect a catalyst system malfunction when the catalyst system's 
conversion capability decreases to the point that emissions exceed the 
emissions thresholds for the catalyst system as shown in Table 2 of this 
paragraph (h).
    (iii) Catalyst system monitoring conditions. The manufacturer must 
define monitoring conditions for malfunctions identified in paragraph 
(h)(6)(ii) of this section in accordance with paragraphs (c) and (d) of 
this section. For purposes of tracking and reporting as required by 
paragraph (d)(1) of this section, all monitors used to detect 
malfunctions identified in paragraph (h)(6)(ii) of this section must be 
tracked separately but reported as a single set of values as specified 
in paragraph (e)(1)(iii) of this section.
    (iv) Catalyst system MIL activation and DTC storage. (A) The MIL 
must activate and DTCs must be stored according to the provisions of 
paragraph (b) of this section.
    (B) The monitoring method for the catalyst system must be capable of 
detecting when a catalyst DTC has been erased (except OBD system self 
erasure), but the catalyst has not been replaced (e.g., catalyst 
overtemperature histogram approaches are not acceptable).
    (7) Evaporative system monitoring--(i) General. The OBD system must 
verify purge flow from the evaporative system and monitor the complete 
evaporative system, excluding the tubing and connections between the 
purge valve and the intake manifold, for vapor leaks to the atmosphere. 
Individual components of the evaporative system (e.g. valves, sensors) 
must be monitored in accordance with the comprehensive components 
requirements in paragraph (i)(3) of this section.
    (ii) Evaporative system malfunction criteria--(A) Purge monitor. The 
OBD system must detect an evaporative system malfunction when no purge 
flow from the evaporative system to the engine can be detected by the 
OBD system.
    (B) Leak monitor. The OBD system must detect an evaporative system 
malfunction when the complete evaporative system contains a leak or 
leaks that cumulatively are greater than or equal to a leak caused by a 
0.150 inch diameter hole.
    (C) The manufacturer may demonstrate that detection of a larger hole 
is more appropriate than that specified in paragraph (h)(7)(ii)(B) of 
this section. To do so, the manufacturer must demonstrate through data 
and/or engineering analyses that holes smaller than the proposed 
detection size would not result in evaporative or running loss emissions 
that exceed 1.5 times the applicable evaporative emissions standards. 
Upon such a demonstration, the proposed detection size could be 
substituted for the requirement of paragraph (h)(7)(ii)(B) of this 
section.
    (iii) Evaporative system monitoring conditions. (A) The manufacturer 
must define monitoring conditions for malfunctions identified in 
paragraph (h)(7)(ii)(A) of this section in accordance with paragraphs 
(c) and (d) of this section.
    (B) The manufacturer must define monitoring conditions for 
malfunctions identified in paragraph (h)(7)(ii)(B) of this section in 
accordance with paragraphs (c) and (d) of this section. For purposes of 
tracking and reporting as required by paragraph (d)(1) of this section, 
all monitors used to detect malfunctions identified in paragraph 
(h)(7)(ii)(B) of this section

[[Page 519]]

must be tracked separately but reported as a single set of values as 
specified in paragraph (e)(1)(iii) of this section.
    (C) The manufacturer may disable or abort an evaporative system 
monitor when the fuel tank level is over 85 percent of nominal tank 
capacity or during a refueling event.
    (D) The manufacturer may request Administrator approval to run the 
evaporative system monitor during only those drive cycles characterized 
as cold starts provided such a condition is needed to ensure reliable 
monitoring. In making the request, the manufacturer must demonstrate 
through data and/or engineering analyses that a reliable monitor can 
only be run on drive cycles that begin with a specific set of cold start 
criteria. A set of cold start criteria based solely on ambient 
temperature exceeding engine coolant temperature will not be acceptable.
    (E) The OBD system may disable temporarily the evaporative purge 
system to run an evaporative system leak monitor.
    (iv) Evaporative system MIL activation and DTC storage. (A) Except 
as provided for in paragraph (h)(7)(iv)(B) of this section, the MIL must 
activate and DTCs must be stored according to the provisions of 
paragraph (b) of this section.
    (B) If the OBD system is capable of discerning that a system leak is 
being caused by a missing or improperly secured gas cap, the OBD system 
need not activate the MIL or store a DTC provided the vehicle is 
equipped with an alternative indicator for notifying the operator of the 
gas cap problem. The alternative indicator must be of sufficient 
illumination and location to be readily visible under all lighting 
conditions. If the vehicle is not equipped with such an alternative 
indicator, the MIL must activate and a DTC be stored as required in 
paragraph (h)(7)(iv)(A) of this section; however, these may be 
deactivated and erased, respectively, if the OBD system determines that 
the gas cap problem has been corrected and the MIL has not been 
activated for any other malfunction. The Administrator may approve other 
strategies that provide equivalent assurance that a vehicle operator 
will be notified promptly of a missing or improperly secured gas cap and 
that corrective action will be undertaken.
    (8) Exhaust gas sensor monitoring--(i) General. (A) The OBD system 
must monitor for malfunctions the output signal, response rate, and any 
other parameter that can affect emissions of all primary (i.e., fuel 
control) exhaust gas sensors (e.g., oxygen, wide-range air/fuel). Both 
the lean-to-rich and rich-to-lean response rates must be monitored.
    (B) The OBD system must also monitor all secondary exhaust gas 
sensors (those used for secondary fuel trim control or as a monitoring 
device) for proper output signal, activity, and response rate.
    (C) For engines equipped with heated exhaust gas sensor, the OBD 
system must monitor the heater for proper performance.
    (ii) Primary exhaust gas sensor malfunction criteria. (A) The OBD 
system must detect a malfunction prior to any failure or deterioration 
of the exhaust gas sensor output voltage, resistance, impedance, 
current, response rate, amplitude, offset, or other characteristic(s) 
(including drift or bias corrected for by secondary sensors) that would 
cause an engine's emissions to exceed the emissions thresholds for 
``other monitors'' as shown in Table 2 of this paragraph (h).
    (B) The OBD system must detect malfunctions of the exhaust gas 
sensor caused by either a lack of circuit continuity or out-of-range 
values.
    (C) The OBD system must detect a malfunction of the exhaust gas 
sensor when a sensor failure or deterioration causes the fuel system to 
stop using that sensor as a feedback input (e.g., causes default or 
open-loop operation).
    (D) The OBD system must detect a malfunction of the exhaust gas 
sensor when the sensor output voltage, resistance, impedance, current, 
amplitude, activity, or other characteristics are no longer sufficient 
for use as an OBD system monitoring device (e.g., for catalyst 
monitoring).
    (iii) Secondary exhaust gas sensor malfunction criteria. (A) The OBD 
system must detect a malfunction prior to any failure or deterioration 
of the exhaust

[[Page 520]]

gas sensor voltage, resistance, impedance, current, response rate, 
amplitude, offset, or other characteristic(s) that would cause an 
engine's emissions to exceed the emissions thresholds for ``other 
monitors'' as shown in Table 2 of this paragraph (h).
    (B) The OBD system must detect malfunctions of the exhaust gas 
sensor caused by a lack of circuit continuity.
    (C) To the extent feasible, the OBD system must detect a malfunction 
of the exhaust gas sensor when the sensor output voltage, resistance, 
impedance, current, amplitude, activity, offset, or other 
characteristics are no longer sufficient for use as an OBD system 
monitoring device (e.g., for catalyst monitoring).
    (D) The OBD system must detect malfunctions of the exhaust gas 
sensor caused by out-of-range values.
    (E) The OBD system must detect a malfunction of the exhaust gas 
sensor when a sensor failure or deterioration causes the fuel system 
(e.g., fuel control) to stop using that sensor as a feedback input 
(e.g., causes default or open-loop operation).
    (iv) Exhaust gas sensor heater malfunction criteria. (A) The OBD 
system must detect a malfunction of the heater performance when the 
current or voltage drop in the heater circuit is no longer within the 
manufacturer's specified limits for normal operation (i.e., within the 
criteria required to be met by the component vendor for heater circuit 
performance at high mileage). Other malfunction criteria for heater 
performance malfunctions may be used upon demonstrating via data or 
engineering analyses that the monitoring reliability and timeliness is 
equivalent to the stated criteria in this paragraph (h)(8)(iv)(A).
    (B) The OBD system must detect malfunctions of the heater circuit 
including open or short circuits that conflict with the commanded state 
of the heater (e.g., shorted to 12 Volts when commanded to 0 Volts 
(ground)).
    (v) Primary exhaust gas sensor monitoring conditions. (A) The 
manufacturer must define monitoring conditions for malfunctions 
identified in paragraphs (h)(8)(ii)(A) and (h)(8)(ii)(D) of this section 
in accordance with paragraphs (c) and (d) of this section. For purposes 
of tracking and reporting as required by paragraph (d)(1) of this 
section, all monitors used to detect malfunctions identified in 
paragraphs (h)(8)(ii)(A) and (h)(8)(ii)(D) of this section must be 
tracked separately but reported as a single set of values as specified 
in paragraph (e)(1)(iii) of this section.
    (B) Except as provided for in paragraph (h)(8)(v)(C) of this 
section, monitoring for malfunctions identified in paragraphs 
(h)(8)(ii)(B) and (h)(8)(ii)(C) of this section must be conducted 
continuously.
    (C) The manufacturer may disable continuous primary exhaust gas 
sensor monitoring when a primary exhaust gas sensor malfunction cannot 
be distinguished from other effects (e.g., disable out-of-range low 
monitoring during fuel cut conditions). To do so, the manufacturer must 
demonstrate via data or engineering analyses that a properly functioning 
sensor cannot be distinguished from a malfunctioning sensor and that the 
disablement interval is limited only to that necessary for avoiding 
false detection.
    (vi) Secondary exhaust gas sensor monitoring conditions. (A) The 
manufacturer must define monitoring conditions for malfunctions 
identified in paragraphs (h)(8)(iii)(A) through (h)(8)(iii)(C) of this 
section in accordance with paragraphs (c) and (d) of this section.
    (B) Except as provided for in paragraph (h)(8)(vi)(C) of this 
section, monitoring for malfunctions identified in paragraphs 
(h)(8)(iii)(D) and (h)(8)(iii)(E) of this section must be conducted 
continuously.
    (C) The manufacturer may disable continuous secondary exhaust gas 
sensor monitoring when a secondary exhaust gas sensor malfunction cannot 
be distinguished from other effects (e.g., disable out-of-range low 
monitoring during fuel cut conditions). To do so, the manufacturer must 
demonstrate via data or engineering analyses that a properly functioning 
sensor cannot be distinguished from a malfunctioning sensor and that the 
disablement interval is limited only to that necessary for avoiding 
false detection.
    (vii) Exhaust gas sensor heater monitoring conditions. (A) The 
manufacturer must define monitoring conditions for malfunctions 
identified in paragraph

[[Page 521]]

(h)(8)(iv)(A) of this section in accordance with paragraphs (c) and (d) 
of this section.
    (B) Monitoring for malfunctions identified in paragraph 
(h)(8)(iv)(B) of this section must be conducted continuously.
    (viii) Exhaust gas sensor MIL activation and DTC storage. The MIL 
must activate and DTCs must be stored according to the provisions of 
paragraph (b) of this section.
    (9) Variable valve timing (VVT) system monitoring--(i) General. The 
OBD system must monitor the VVT system on engines so equipped for target 
error and slow response malfunctions. The individual electronic 
components (e.g., actuators, valves, sensors) that are used in the VVT 
system must be monitored in accordance with the comprehensive components 
requirements in paragraph (i)(3).
    (ii) VVT system malfunction criteria--(A) VVT system target error. 
The OBD system must detect a malfunction prior to any failure or 
deterioration in the capability of the VVT system to achieve the 
commanded valve timing and/or control within a crank angle and/or lift 
tolerance that would cause an engine's emissions to exceed the emission 
thresholds for ``other monitors'' as shown in Table 2 of this paragraph 
(h).
    (B) VVT slow response. The OBD system must detect a malfunction 
prior to any failure or deterioration in the capability of the VVT 
system to achieve the commanded valve timing and/or control within a 
manufacturer-specified time that would cause an engine's emissions to 
exceed the emission thresholds for ``other monitors'' as shown in Table 
2 of this paragraph (h).
    (C) For engines in which no failure or deterioration of the VVT 
system could result in an engine's emissions exceeding the applicable 
emissions thresholds of paragraphs (h)(9)(ii)(A) and (h)(9)(ii)(B) of 
this section, the OBD system must detect a malfunction of the VVT system 
when proper functional response of the system to computer commands does 
not occur.
    (iii) VVT system monitoring conditions. Manufacturers must define 
the monitoring conditions for VVT system malfunctions identified in 
paragraph (h)(9)(ii) in accordance with paragraphs (c) and (d) of this 
section, with the exception that monitoring must occur every time the 
monitoring conditions are met during the drive cycle rather than once 
per drive cycle as required in paragraph (c)(2) of this section. For 
purposes of tracking and reporting as required in paragraph (d)(1) of 
this section, all monitors used to detect malfunctions identified in 
paragraph (h)(9)(ii) must be tracked separately but reported as a single 
set of values as specified in paragraph (e)(1)(iii) of this section.
    (iv) VVT MIL activation and DTC storage. The MIL must activate and 
DTCs must be stored according to the provisions of paragraph (b) of this 
section.
    (i) OBD monitoring requirements for all engines--(1) Engine cooling 
system monitoring--(i) General. (A) The OBD system must monitor the 
thermostat on engines so equipped for proper operation.
    (B) The OBD system must monitor the engine coolant temperature (ECT) 
sensor for electrical circuit continuity, out-of-range values, and 
rationality malfunctions.
    (C) For engines that use a system other than the cooling system and 
ECT sensor (e.g., oil temperature, cylinder head temperature) to 
determine engine operating temperature for emission control purposes 
(e.g., to modify spark or fuel injection timing or quantity), the 
manufacturer may forego cooling system monitoring and instead monitor 
the components or systems used in their approach. To do so, the 
manufacturer must to submit data and/or engineering analyses that 
demonstrate that their monitoring plan is as reliable and effective as 
the monitoring required in this paragraph (i)(1).
    (ii) Malfunction criteria for the thermostat. (A) The OBD system 
must detect a thermostat malfunction if, within the manufacturer 
specified time interval following engine start, any of the following 
conditions occur: The coolant temperature does not reach the highest 
temperature required by the OBD system to enable other diagnostics; and, 
the coolant temperature does not reach a warmed-up temperature within 20 
degrees Fahrenheit of the manufacturer's nominal thermostat regulating 
temperature. For the second of these two

[[Page 522]]

conditions, the manufacturer may use a lower temperature for this 
criterion if either the manufacturer can demonstrate that the fuel, 
spark timing, and/or other coolant temperature-based modification to the 
engine control strategies would not cause an emissions increase greater 
than or equal to 50 percent of any of the applicable emissions 
standards; or, ambient air temperature is between 20 degrees Fahrenheit 
and 50 degrees Fahrenheit in which case, upon Administrator approval, 
the minimum coolant temperature required to be reached may be decreased 
based on the ambient air temperature.
    (B) With Administrator approval, the manufacturer may use 
alternative malfunction criteria to those of paragraph (i)(1)(ii)(A) of 
this section and/or alternative monitoring conditions to those of 
paragraph (i)(1)(iv) of this section that are a function of temperature 
at engine start on engines that do not reach the temperatures specified 
in the malfunction criteria when the thermostat is functioning properly. 
To do so, the manufacturer is required to submit data and/or engineering 
analyses that demonstrate that a properly operating system does not 
reach the specified temperatures and that the possibility is minimized 
for cooling system malfunctions to go undetected thus disabling other 
OBD monitors.
    (C) The manufacturer may request Administrator approval to forego 
monitoring of the thermostat if the manufacturer can demonstrate that a 
malfunctioning thermostat cannot cause a measurable increase in 
emissions during any reasonable driving condition nor cause any 
disablement of other OBD monitors.
    (iii) Malfunction criteria for the ECT sensor--(A) Circuit 
integrity. The OBD system must detect malfunctions of the ECT sensor 
related to a lack of circuit continuity or out-of-range values.
    (B) Time to reach closed-loop/feedback enable temperature. The OBD 
system must detect if, within the manufacturer specified time interval 
following engine start, the ECT sensor does not achieve the highest 
stabilized minimum temperature that is needed to initiate closed-loop/
feedback control of all affected emission control systems (e.g., fuel 
system, EGR system). The manufacturer specified time interval must be a 
function of the engine coolant temperature and/or intake air temperature 
at startup. The manufacturer time interval must be supported by data 
and/or engineering analyses demonstrating that it provides robust 
monitoring and minimizes the likelihood of other OBD monitors being 
disabled. The manufacturer may forego the requirements of this paragraph 
(i)(1)(iii)(B) provided the manufacturer does not use engine coolant 
temperature or the ECT sensor to enable closed-loop/feedback control of 
any emission control systems.
    (C) Stuck in range below the highest minimum enable temperature. To 
the extent feasible when using all available information, the OBD system 
must detect a malfunction if the ECT sensor inappropriately indicates a 
temperature below the highest minimum enable temperature required by the 
OBD system to enable other monitors (e.g., an OBD system that requires 
ECT to be greater than 140 degrees Fahrenheit to enable a diagnostic 
must detect malfunctions that cause the ECT sensor to inappropriately 
indicate a temperature below 140 degrees Fahrenheit). The manufacturer 
may forego this requirement for temperature regions in which the 
monitors required under paragraphs (i)(1)(ii) or (i)(1)(iii)(B) of this 
section will detect ECT sensor malfunctions as defined in this paragraph 
(i)(1)(iii)(C).
    (D) Stuck in range above the lowest maximum enable temperature. The 
OBD system must detect a malfunction if the ECT sensor inappropriately 
indicates a temperature above the lowest maximum enable temperature 
required by the OBD system to enable other monitors (e.g., an OBD system 
that requires an engine coolant temperature less than 90 degrees 
Fahrenheit at startup prior to enabling an OBD monitor must detect 
malfunctions that cause the ECT sensor to indicate inappropriately a 
temperature above 90 degrees Fahrenheit). The manufacturer may forego 
this requirement within temperature regions in which the monitors 
required under paragraphs (i)(1)(ii), (i)(1)(iii)(B), (i)(1)(iii)(C) of 
this section will detect ECT sensor

[[Page 523]]

malfunctions as defined in this paragraph (i)(1)(iii)(D) or in which the 
MIL will be activated according to the provisions of paragraph (b)(2)(v) 
of this section. The manufacturer may also forego this monitoring within 
temperature regions where a temperature gauge on the instrument panel 
indicates a temperature in the ``red zone'' (engine overheating zone) 
and displays the same temperature information as used by the OBD system.
    (iv) Monitoring conditions for the thermostat. (A) The manufacturer 
must define the monitoring conditions for malfunctions identified in 
paragraph (i)(1)(ii)(A) of this section in accordance with paragraph (c) 
of this section. Additionally, except as provided for in paragraphs 
(i)(1)(iv)(B) and (i)(1)(iv)(C) of this section, monitoring for 
malfunctions identified in paragraph (i)(1)(ii)(A) of this section must 
be conducted once per drive cycle on every drive cycle in which the ECT 
sensor indicates, at engine start, a temperature lower than the 
temperature established as the malfunction criteria in paragraph 
(i)(1)(ii)(A) of this section.
    (B) The manufacturer may disable thermostat monitoring at ambient 
engine start temperatures below 20 degrees Fahrenheit.
    (C) The manufacturers may request Administrator approval to suspend 
or disable thermostat monitoring if the engine is subjected to 
conditions that could lead to false diagnosis. To do so, the 
manufacturer must submit data and/or engineering analyses that 
demonstrate that the suspension or disablement is necessary. In general, 
the manufacturer will not be allowed to suspend or disable the 
thermostat monitor on engine starts where the engine coolant temperature 
at engine start is more than 35 degrees Fahrenheit lower than the 
thermostat malfunction threshold temperature determined under paragraph 
(i)(1)(ii)(A) of this section.
    (v) Monitoring conditions for the ECT sensor. (A) Except as provided 
for in paragraph (i)(1)(v)(D) of this section, the OBD system must 
monitor continuously for malfunctions identified in paragraph monitoring 
for malfunctions identified in paragraph (i)(1)(iii)(A) of this section 
(i.e., circuit integrity and out-of-range).
    (B) The manufacturer must define the monitoring conditions for 
malfunctions identified in paragraph (i)(1)(iii)(B) of this section in 
accordance with paragraph (c) of this section. Additionally, except as 
provided for in paragraph (i)(1)(v)(D) of this section, monitoring for 
malfunctions identified in paragraph (i)(1)(iii)(B) of this section must 
be conducted once per drive cycle on every drive cycle in which the ECT 
sensor indicates a temperature lower than the closed-loop enable 
temperature at engine start (i.e., all engine start temperatures greater 
than the ECT sensor out-of-range low temperature and less than the 
closed-loop enable temperature).
    (C) The manufacturer must define the monitoring conditions for 
malfunctions identified in paragraphs (i)(1)(iii)(C) and (i)(1)(iii)(D) 
of this section in accordance with paragraphs (c) and (d) of this 
section.
    (D) The manufacturer may suspend or delay the monitor for the time 
to reach closed-loop enable temperature if the engine is subjected to 
conditions that could lead to false diagnosis (e.g., vehicle operation 
at idle for more than 50 to 75 percent of the warm-up time).
    (E) The manufacturer may request Administrator approval to disable 
continuous ECT sensor monitoring when an ECT sensor malfunction cannot 
be distinguished from other effects. To do so, the manufacturer must 
submit data and/or engineering analyses that demonstrate a properly 
functioning sensor cannot be distinguished from a malfunctioning sensor 
and that the disablement interval is limited only to that necessary for 
avoiding false detection.
    (vi) Engine cooling system MIL activation and DTC storage. The MIL 
must activate and DTCs must be stored according to the provisions of 
paragraph (b) of this section.
    (2) Crankcase ventilation (CV) system monitoring--(i) General. The 
OBD system must monitor the CV system on engines so equipped for system 
integrity. Engines not required to be equipped with CV systems are 
exempt from monitoring the CV system. For diesel engines, the 
manufacturer must

[[Page 524]]

submit a plan for Administrator approval prior to OBD certification. 
That plan must include descriptions of the monitoring strategy, 
malfunction criteria, and monitoring conditions for CV system 
monitoring. The plan must demonstrate that the CV system monitor is of 
equivalent effectiveness, to the extent feasible, to the malfunction 
criteria and the monitoring conditions of this paragraph (i)(2).
    (ii) Crankcase ventilation system malfunction criteria. (A) For the 
purposes of this paragraph (i)(2), ``CV system'' is defined as any form 
of crankcase ventilation system, regardless of whether it utilizes 
positive pressure. ``CV valve'' is defined as any form of valve or 
orifice used to restrict or control crankcase vapor flow. Further, any 
additional external CV system tubing or hoses used to equalize crankcase 
pressure or to provide a ventilation path between various areas of the 
engine (e.g., crankcase and valve cover) are considered part of the CV 
system ``between the crankcase and the CV valve'' and subject to the 
malfunction criteria in paragraph (i)(2)(ii)(B) of this section.
    (B) Except as provided for in paragraphs (i)(2)(ii)(C) through 
(i)(2)(ii)(E) of this section, the OBD system must detect a malfunction 
of the CV system when a disconnection of the system occurs between 
either the crankcase and the CV valve, or between the CV valve and the 
intake manifold.
    (C) The manufacturer may forego monitoring for a disconnection 
between the crankcase and the CV valve provided the CV system is 
designed such that the CV valve is fastened directly to the crankcase 
such that it is significantly more difficult to remove the CV valve from 
the crankcase than to disconnect the line between the CV valve and the 
intake manifold (taking aging effects into consideration). To do so, the 
manufacturer must be able to provide data and/or an engineering 
evaluation demonstrating that the CV system is so designed.
    (D) The manufacturer may forego monitoring for a disconnection 
between the crankcase and the CV valve provided the CV system is 
designed such that it uses tubing connections between the CV valve and 
the crankcase that are: resistant to deterioration or accidental 
disconnection; significantly more difficult to disconnect than is the 
line between the CV valve and the intake manifold; and, not subject to 
disconnection per the manufacturer's repair procedures for any non-CV 
system repair. To do so, the manufacturer must be able to provide data 
and/or engineering evaluation demonstrating that the CV system is so 
designed.
    (E) The manufacturer may forego monitoring for a disconnection 
between the CV valve and the intake manifold provided the CV system is 
designed such that any disconnection either causes the engine to stall 
immediately during idle operation, or is unlikely to occur due to a CV 
system design that is integral to the induction system (e.g., machined 
passages rather than tubing or hoses). To do so, the manufacturer must 
be able to provide data and/or an engineering evaluation demonstrating 
that the CV system is so designed.
    (iii) Crankcase ventilation system monitoring conditions. The 
manufacturer must define the monitoring conditions for malfunctions 
identified in paragraph (i)(2) of this section in accordance with 
paragraphs (c) and (d) of this section.
    (iv) Crankcase ventilation system MIL activation and DTC storage. 
The MIL must activate and DTCs must be stored according to the 
provisions of paragraph (b) of this section. The stored DTC need not 
identify specifically the CV system (e.g., a DTC for idle speed control 
or fuel system monitoring can be stored) if the manufacturer can 
demonstrate that additional monitoring hardware is necessary to make 
such an identification and provided the manufacturer's diagnostic and 
repair procedures for the detected malfunction include directions to 
check the integrity of the CV system.
    (3) Comprehensive component monitoring--(i) General. Except as 
provided for in paragraph (i)(4) of this section, the OBD system must 
detect a malfunction of any electronic engine component or system not 
otherwise described in paragraphs (g), (h), (i)(1), and (i)(2) of this 
section that either provides input to (directly or indirectly, such 
components may include the

[[Page 525]]

crank angle sensor, knock sensor, throttle position sensor, cam position 
sensor, intake air temperature sensor, boost pressure sensor, manifold 
pressure sensor, mass air flow sensor, exhaust temperature sensor, 
exhaust pressure sensor, fuel pressure sensor, fuel composition sensor 
of a flexible fuel vehicle, etc.) or receives commands from (such 
components or systems may include the idle speed control system, glow 
plug system, variable length intake manifold runner systems, 
supercharger or turbocharger electronic components, heated fuel 
preparation systems, the wait-to-start lamp on diesel applications, the 
MIL, etc.) the onboard computer(s) and meets either of the criteria 
described in paragraphs (i)(3)(i)(A) and/or (i)(3)(i)(B) of this 
section. Note that, for the purposes of this paragraph (i)(3), 
``electronic engine component or system'' does not include components 
that are driven by the engine and are not related to the control of the 
fueling, air handling, or emissions of the engine (e.g., PTO components, 
air conditioning system components, and power steering components).
    (A) It can cause emissions to exceed applicable emission standards. 
To preclude monitoring, the manufacturer must be able to provide 
emission data showing that the component or system, when malfunctioning 
and installed on a suitable test engine, does not cause emissions to 
exceed the emission standards.
    (B) It is used as part of the monitoring strategy for any other 
monitored system or component.
    (ii) Comprehensive component malfunction criteria for input 
components. (A) The OBD system must detect malfunctions of input 
components caused by a lack of circuit continuity and out-of-range 
values. In addition, where feasible, rationality checks must also be 
done and shall verify that a sensor output is neither inappropriately 
high nor inappropriately low (i.e., ``two-sided'' monitoring).
    (B) To the extent feasible, the OBD system must separately detect 
and store different DTCs that distinguish rationality malfunctions from 
lack of circuit continuity and out-of-range malfunctions. For lack of 
circuit continuity and out-of-range malfunctions, the OBD system must, 
to the extent feasible, separately detect and store different DTCs for 
each distinct malfunction (e.g., out-of-range low, out-of-range high, 
open circuit). The OBD system is not required to store separate DTCs for 
lack of circuit continuity malfunctions that cannot be distinguished 
from other out-of-range circuit malfunctions.
    (C) For input components that are used to activate alternative 
strategies that can affect emissions (e.g., AECDs, engine shutdown 
systems), the OBD system must conduct rationality checks to detect 
malfunctions that cause the system to activate erroneously or deactivate 
the alternative strategy. To the extent feasible when using all 
available information, the rationality check must detect a malfunction 
if the input component inappropriately indicates a value that activates 
or deactivates the alternative strategy. For example, for an alternative 
strategy that activates when the intake air temperature is greater than 
120 degrees Fahrenheit, the OBD system must detect malfunctions that 
cause the intake air temperature sensor to indicate inappropriately a 
temperature above 120 degrees Fahrenheit.
    (D) For engines that require precise alignment between the camshaft 
and the crankshaft, the OBD system must monitor the crankshaft position 
sensor(s) and camshaft position sensor(s) to verify proper alignment 
between the camshaft and crankshaft in addition to monitoring the 
sensors for circuit continuity and proper rationality. Proper alignment 
monitoring between a camshaft and a crankshaft is required only in cases 
where both are equipped with position sensors. For engines equipped with 
VVT systems and a timing belt or chain, the OBD system must detect a 
malfunction if the alignment between the camshaft and crankshaft is off 
by one or more cam/crank sprocket cogs (e.g., the timing belt/chain has 
slipped by one or more teeth/cogs). If a manufacturer demonstrates that 
a single tooth/cog misalignment cannot cause a measurable increase in 
emissions during any reasonable driving condition, the OBD system must 
detect a malfunction when the minimum number of

[[Page 526]]

teeth/cogs misalignment has occurred that does cause a measurable 
emission increase.
    (iii) Comprehensive component malfunction criteria for output 
components/systems. (A) The OBD system must detect a malfunction of an 
output component/system when proper functional response does not occur 
in response to computer commands. If such a functional check is not 
feasible, the OBD system must detect malfunctions of output components/
systems caused by a lack of circuit continuity or circuit malfunction 
(e.g., short to ground or high voltage). For output component lack of 
circuit continuity malfunctions and circuit malfunctions, the OBD system 
is not required to store different DTCs for each distinct malfunction 
(e.g., open circuit, shorted low). Manufacturers are not required to 
activate an output component/system when it would not normally be active 
for the sole purpose of performing a functional check of it as required 
in this paragraph (i)(3).
    (B) For gasoline engines, the idle control system must be monitored 
for proper functional response to computer commands. For gasoline 
engines using monitoring strategies based on deviation from target idle 
speed, a malfunction must be detected when either of the following 
conditions occurs: The idle speed control system cannot achieve the 
target idle speed within 200 revolutions per minute (rpm) above the 
target speed or 100 rpm below the target speed; or, the idle speed 
control system cannot achieve the target idle speed within the smallest 
engine speed tolerance range required by the OBD system to enable any 
other monitors. Regarding the former of these conditions, the 
manufacturer may use larger engine speed tolerances. To do so, the 
manufacturer must be able to provide data and/or engineering analyses 
that demonstrate that the tolerances can be exceeded without a 
malfunction being present.
    (C) For diesel engines, the idle control system must be monitored 
for proper functional response to computer commands. For diesel engines, 
a malfunction must be detected when either of the following conditions 
occurs: the idle fuel control system cannot achieve the target idle 
speed or fuel injection quantity within 50 percent 
of the manufacturer-specified fuel quantity and engine speed tolerances; 
or, the idle fuel control system cannot achieve the target idle speed or 
fueling quantity within the smallest engine speed or fueling quantity 
tolerance range required by the OBD system to enable any other monitors.
    (D) For model years 2010 through 2012, glow plugs must be monitored 
for circuit continuity malfunctions. For model years 2010 and later, 
intake air heater systems and, for model years 2013 and later, glow 
plugs must be monitored for proper functional response to computer 
commands and for circuit continuity malfunctions. The glow plug/intake 
air heater circuit(s) must be monitored for proper current and voltage 
drop. The manufacturer may use other monitoring strategies but must be 
able to provide data and/or engineering analyses that demonstrate 
reliable and timely detection of malfunctions. The OBD system must also 
detect a malfunction when a single glow plug no longer operates within 
the manufacturer's specified limits for normal operation. If a 
manufacturer can demonstrate that a single glow plug malfunction cannot 
cause a measurable increase in emissions during any reasonable driving 
condition, the OBD system must instead detect a malfunction when the 
number of glow plugs needed to cause an emission increase is 
malfunctioning. To the extent feasible, the stored DTC must identify the 
specific malfunctioning glow plug(s).
    (E) The wait-to-start lamp circuit and the MIL circuit must be 
monitored for malfunctions that cause either lamp to fail to activate 
when commanded to do so (e.g., burned out bulb). This monitoring of the 
wait-to-start lamp circuit and the MIL circuit is not required for wait-
to-start lamps and MILs using light-emitting diodes (LEDs).
    (iv) Monitoring conditions for input components. (A) The OBD system 
must monitor input components continuously for out-of-range values and 
circuit continuity. The manufacturer may disable continuous monitoring 
for circuit continuity and out-of-range values

[[Page 527]]

when a malfunction cannot be distinguished from other effects. To do so, 
the manufacturer must be able to provide data and/or engineering 
analyses that demonstrate that a properly functioning input component 
cannot be distinguished from a malfunctioning input component and that 
the disablement interval is limited only to that necessary for avoiding 
false malfunction detection.
    (B) For input component rationality checks (where applicable), the 
manufacturer must define the monitoring conditions for detecting 
malfunctions in accordance with paragraphs (c) and (d) of this section, 
with the exception that rationality checks must occur every time the 
monitoring conditions are met during the drive cycle rather than once 
per drive cycle as required in paragraph (c)(2) of this section.
    (v) Monitoring conditions for output components/systems. (A) The OBD 
system must monitor output components/systems continuously for circuit 
continuity and circuit malfunctions. The manufacturer may disable 
continuous monitoring for circuit continuity and circuit malfunctions 
when a malfunction cannot be distinguished from other effects. To do so, 
the manufacturer must be able to provide data and/or engineering 
analyses that demonstrate that a properly functioning output component/
system cannot be distinguished from a malfunctioning one and that the 
disablement interval is limited only to that necessary for avoiding 
false malfunction detection.
    (B) For output component/system functional checks, the manufacturer 
must define the monitoring conditions for detecting malfunctions in 
accordance with paragraphs (c) and (d) of this section. Specifically for 
the idle control system, the manufacturer must define the monitoring 
conditions for detecting malfunctions in accordance with paragraphs (c) 
and (d) of this section, with the exception that functional checks must 
occur every time the monitoring conditions are met during the drive 
cycle rather than once per drive cycle as required in paragraph (c)(2) 
of this section.
    (vi) Comprehensive component MIL activation and DTC storage. (A) 
Except as provided for in paragraphs (i)(3)(vi)(B) and (i)(3)(vi)(C) of 
this section, the MIL must activate and DTCs must be stored according to 
the provisions of paragraph (b) of this section.
    (B) The MIL need not be activated in conjunction with storing a MIL-
on DTC for any comprehensive component if: the component or system, when 
malfunctioning, could not cause engine emissions to increase by 15 
percent or more of the applicable FTP standard during any reasonable 
driving condition; or, the component or system is not used as part of 
the monitoring strategy for any other system or component that is 
required to be monitored.
    (C) The MIL need not be activated if a malfunction has been detected 
in the MIL circuit that prevents the MIL from activating (e.g., burned 
out bulb or light-emitting diode, LED). Nonetheless, the electronic MIL 
status (see paragraph (k)(4)(ii) of this section) must be reported as 
MIL commanded-on and a MIL-on DTC must be stored.
    (4) Other emission control system monitoring--(i) General. For other 
emission control systems that are either not addressed in paragraphs (g) 
through (i)(3) of this section (e.g., hydrocarbon traps, homogeneous 
charge compression ignition control systems), or addressed in paragraph 
(i)(3) of this section but not corrected or compensated for by an 
adaptive control system (e.g., swirl control valves), the manufacturer 
must submit a plan for Administrator approval of the monitoring 
strategy, malfunction criteria, and monitoring conditions prior to 
introduction on a production engine. The plan must demonstrate the 
effectiveness of the monitoring strategy, the malfunction criteria used, 
the monitoring conditions required by the monitor, and, if applicable, 
the determination that the requirements of paragraph (i)(4)(ii) of this 
section are satisfied.
    (ii) For engines that use emission control systems that alter intake 
air flow or cylinder charge characteristics by actuating valve(s), 
flap(s), etc., in the intake air delivery system (e.g., swirl control 
valve systems), the manufacturer, in addition to meeting the 
requirements of paragraph (i)(4)(i) of this section, may elect to have 
the OBD system monitor the shaft to which all

[[Page 528]]

valves in one intake bank are physically attached rather than performing 
a functional check of the intake air flow, cylinder charge, or 
individual valve(s)/flap(s). For non-metal shafts or segmented shafts, 
the monitor must verify all shaft segments for proper functional 
response (e.g., by verifying that the segment or portion of the shaft 
farthest from the actuator functions properly). For systems that have 
more than one shaft to operate valves in multiple intake banks, the 
manufacturer is not required to add more than one set of detection 
hardware (e.g., sensor, switch) per intake bank to meet this 
requirement.
    (5) Exceptions to OBD monitoring requirements. (i) The Administrator 
may revise the PM filtering performance malfunction criteria for DPFs to 
exclude detection of specific failure modes such as partially melted 
substrates, if the most reliable monitoring method developed requires 
it.
    (ii) The manufacturer may disable an OBD system monitor at ambient 
engine start temperatures below 20 degrees Fahrenheit (low ambient 
temperature conditions may be determined based on intake air or engine 
coolant temperature at engine start) or at elevations higher than 8,000 
feet above sea level. To do so, the manufacturer must submit data and/or 
engineering analyses that demonstrate that monitoring is unreliable 
during the disable conditions. A manufacturer may request that an OBD 
system monitor be disabled at other ambient engine start temperatures by 
submitting data and/or engineering analyses demonstrating that 
misdiagnosis would occur at the given ambient temperatures due to their 
effect on the component itself (e.g., component freezing).
    (iii) The manufacturer may disable an OBD system monitor when the 
fuel level is 15 percent or less of the nominal fuel tank capacity for 
those monitors that can be affected by low fuel level or running out of 
fuel (e.g., misfire detection). To do so, the manufacturer must submit 
data and/or engineering analyses that demonstrate that monitoring at the 
given fuel levels is unreliable, and that the OBD system is still able 
to detect a malfunction if the component(s) used to determine fuel level 
indicates erroneously a fuel level that causes the disablement.
    (iv) The manufacturer may disable OBD monitors that can be affected 
by engine battery or system voltage levels.
    (A) For an OBD monitor affected by low vehicle battery or system 
voltages, manufacturers may disable monitoring when the battery or 
system voltage is below 11.0 Volts. The manufacturer may use a voltage 
threshold higher than 11.0 Volts to disable monitors but must submit 
data and/or engineering analyses that demonstrate that monitoring at 
those voltages is unreliable and that either operation of a vehicle 
below the disablement criteria for extended periods of time is unlikely 
or the OBD system monitors the battery or system voltage and will detect 
a malfunction at the voltage used to disable other monitors.
    (B) For an OBD monitor affected by high engine battery or system 
voltages, the manufacturer may disable monitoring when the battery or 
system voltage exceeds a manufacturer-defined voltage. To do so, the 
manufacturer must submit data and/or engineering analyses that 
demonstrate that monitoring above the manufacturer-defined voltage is 
unreliable and that either the electrical charging system/alternator 
warning light will be activated (or voltage gauge would be in the ``red 
zone'') or the OBD system monitors the battery or system voltage and 
will detect a malfunction at the voltage used to disable other monitors.
    (v) The manufacturer may also disable affected OBD monitors in 
systems designed to accommodate the installation of power take off (PTO) 
units provided monitors are disabled only while the PTO unit is active 
and the OBD readiness status (see paragraph (k)(4)(i) of this section) 
is cleared by the onboard computer (i.e., all monitors set to indicate 
``not complete'' or ``not ready'') while the PTO unit is activated. If 
monitors are so disabled and when the disablement ends, the readiness 
status may be restored to its state prior to PTO activation.
    (6) Feedback control system monitoring. If the engine is equipped 
with feedback control of any of the systems covered

[[Page 529]]

in paragraphs (g), (h) and (i) of this section, then the OBD system must 
detect as malfunctions the conditions specified in this paragraph (i)(6) 
for each of the individual feedback controls.
    (i) The OBD system must detect when the system fails to begin 
feedback control within a manufacturer specified time interval.
    (ii) When any malfunction or deterioration causes open loop or limp-
home operation.
    (iii) When feedback control has used up all of the adjustment 
allowed by the manufacturer.
    (iv) A manufacturer may temporarily disable monitoring for 
malfunctions specified in paragraph (i)(6)(iii) of this section during 
conditions that the specific monitor cannot distinguish robustly between 
a malfunctioning system and a properly operating system. To do so, the 
manufacturer is required to submit data and/or engineering analyses 
demonstrating that the individual feedback control system, when 
operating as designed on an engine with all emission controls working 
properly, routinely operates during these conditions while having used 
up all of the adjustment allowed by the manufacturer. In lieu of 
detecting, with a system specific monitor, the malfunctions specified in 
paragraphs (i)(6)(i) and (i)(6)(ii) of this section the OBD system may 
monitor the individual parameters or components that are used as inputs 
for individual feedback control systems provided that the monitors 
detect all malfunctions that meet the criteria of paragraphs (i)(6)(i) 
and (i)(6)(ii) of this section.
    (j) Production evaluation testing--(1) Verification of 
standardization requirements. (i) For model years 2013 and later, the 
manufacturer must perform testing to verify that production vehicles 
meet the requirements of paragraphs (k)(3) and (k)(4) of this section 
relevant to the proper communication of required emissions-related 
messages to a SAE J1978 or SAE J1939 (both as specified in paragraph 
(k)(1) of this section) scan tool.
    (ii) Selection of test vehicles. (A) The manufacturer must perform 
this testing every model year on ten unique production vehicles (i.e., 
engine rating and chassis application combination) per engine family. If 
there are less than ten unique production vehicles for a certain engine 
family, the manufacturer must test each unique production vehicle in 
that engine family. The manufacturer must perform this testing within 
either three months of the start of engine production or one month of 
the start of vehicle production, whichever is later. The manufacturer 
may request approval to group multiple production vehicles together and 
test one representative vehicle per group. To do so, the software and 
hardware designed to comply with the standardization requirements of 
paragraph (k)(1) of this section (e.g., communication protocol message 
timing, number of supported data stream parameters, engine and vehicle 
communication network architecture) in the representative vehicle must 
be identical to all others in the group and any differences in the 
production vehicles cannot be relevant with respect to meeting the 
criteria of paragraph (j)(1)(iv) of this section.
    (B) For 2016 and subsequent model years, the required number of 
vehicles to be tested shall be reduced to five per engine family 
provided zero vehicles fail the testing required by paragraph (j)(1) of 
this section for two consecutive years.
    (C) For 2019 and subsequent model years, the required number of 
vehicles to be tested shall be reduced to three per engine family 
provided zero vehicles fail the testing required by paragraph (j)(1) of 
this section for three consecutive years.
    (D) The requirement for submittal of data from one or more of the 
production vehicles shall be waived if data have been submitted 
previously for all of the production vehicles. The manufacturer may 
request approval to carry over data collected in previous model years. 
To do so, the software and hardware designed to comply with the 
standardization requirements of paragraph (k)(1) of this section must be 
identical to the previous model year and there must not have been other 
hardware or software changes that affect compliance with the 
standardization requirements.

[[Page 530]]

    (E) For hybrid engine families with projected U.S.-directed 
production volume of less than 5,000 engines, the manufacturers are only 
required to test one engine-hybrid combination per family.
    (iii) Test equipment. For the testing required by paragraph (j)(1) 
of this section, the manufacturer shall use an off-board device to 
conduct the testing. The manufacturer must be able to show that the off-
board device is able to verify that the vehicles tested using the device 
are able to perform all of the required functions in paragraph 
(j)(1)(iv) of this section with any other off-board device designed and 
built in accordance with the SAE J1978 or SAE J1939 (both as specified 
in paragraph (k)(1) of this section) generic scan tool specifications.
    (iv) Required testing. The testing must verify that communication 
can be established properly between all emission-related on-board 
computers and a SAE J1978 or SAE J1939 (both as specified in paragraph 
(k)(1) of this section) scan tool designed to adhere strictly to the 
communication protocols allowed in paragraph (k)(3) of this section. The 
testing must also verify that all emission-related information is 
communicated properly between all emission-related on-board computers 
and a SAE J1978 or SAE J1939 (both as specified in paragraph (k)(1) of 
this section) scan tool in accordance with the requirements of paragraph 
(k)(1) of this section and the applicable ISO and SAE specifications 
including specifications for physical layer, network layer, message 
structure, and message content. The testing must also verify that the 
onboard computer(s) can properly respond to a SAE J1978 or SAE J1939 
(both as specified in paragraph (k)(1) of this section) scan tool 
request to clear emissions-related DTCs and reset the ready status in 
accordance with paragraph (k)(4)(ix) of this section. The testing must 
further verify that the following information can be properly 
communicated to a SAE J1978 or SAE J1939 (both as specified in paragraph 
(k)(1) of this section) scan tool:
    (A) The current ready status from all onboard computers required to 
support ready status in accordance with SAE J1978 or SAE J1939-73 (both 
as specified in paragraph (k)(1) of this section) and paragraph 
(k)(4)(i) of this section in the key-on, engine-off position and while 
the engine is running.
    (B) The MIL command status while a deactivated MIL is commanded and 
while an activated MIL is commanded in accordance with SAE J1979 or SAE 
J1939 (both as specified in paragraph (k)(1) of this section) and 
paragraph (k)(4)(ii) of this section in the key-on, engine-off position 
and while the engine is running, and in accordance with SAE J1979 or SAE 
J1939 (both as specified in paragraph (k)(1) of this section) and 
paragraphs (b)(1)(ii) of this section during the MIL functional check, 
if applicable, and, if applicable, (k)(4)(i)(C) of this section during 
the MIL ready status check while the engine is off.
    (C) All data stream parameters required in paragraph (k)(4)(ii) of 
this section in accordance with SAE J1979 or SAE J1939 (both as 
specified in paragraph (k)(1) of this section) including, if applicable, 
the proper identification of each data stream parameter as supported in 
SAE J1979 (e.g., Mode/Service $01, PID $00).
    (D) The CAL ID, CVN, and VIN as required by paragraphs (k)(4)(vi), 
(k)(4)(vii), and (k)(4)(viii) of this section and in accordance with SAE 
J1979 or SAE J1939 (both as specified in paragraph (k)(1) of this 
section).
    (E) An emissions-related DTC (permanent, pending, MIL-on, previous-
MIL-on) in accordance with SAE J1979 or SAE J1939-73 (both as specified 
in paragraph (k)(1) of this section) including the correct indication of 
the number of stored DTCs (e.g., Mode/Service $01, PID $01, Data A for 
SAE J1979 (as specified in paragraph (k)(1) of this section)) and 
paragraph (k)(4)(iv) of this section.
    (v) Reporting of results. The manufacturer must submit to the 
Administrator the following, based on the results of the testing 
required by paragraph (j)(1)(iv) of this section:
    (A) If a variant meets all the requirements of paragraph (j)(1)(iv) 
of this section, a statement specifying that the variant passed all the 
tests. Upon request from the Administrator, the detailed results of any 
such testing may have to be submitted.

[[Page 531]]

    (B) If any variant does not meet the requirements paragraph 
(j)(1)(iv) of this section, a written report detailing the problem(s) 
identified and the manufacturer's proposed corrective action (if any) to 
remedy the problem(s). This report must be submitted within one month of 
testing the specific variant. The Administrator will consider the 
proposed remedy and, if in disagreement, will work with the manufacturer 
to propose an alternative remedy. Factors to be considered by the 
Administrator in considering the proposed remedy will include the 
severity of the problem(s), the ability of service technicians to access 
the required diagnostic information, the impact on equipment and tool 
manufacturers, and the amount of time prior to implementation of the 
proposed corrective action.
    (vi) Alternative testing protocols. Manufacturers may request 
approval to use other testing protocols. To do so, the manufacturer must 
demonstrate that the alternative testing methods and equipment will 
provide an equivalent level of verification of compliance with the 
standardization requirements as is required by paragraph (j)(1) of this 
section.
    (2) Verification of monitoring requirements. (i) Within either the 
first six months of the start of engine production or the first three 
months of the start of vehicle production, whichever is later, the 
manufacturer must conduct a complete evaluation of the OBD system of one 
or more production vehicles (test vehicles) and submit the results of 
the evaluation to the Administrator.
    (ii) Selection of test vehicles. (A) For each engine selected for 
monitoring system demonstration in paragraph (l) of this section, the 
manufacturer must evaluate one production vehicle equipped with an 
engine from the same engine family and rating as the demonstration 
engine. The vehicle selection must be approved by the Administrator.
    (B) If the manufacturer is required to test more than one test 
vehicle, the manufacturer may test an engine in lieu of a vehicle for 
all but one of the required test vehicles.
    (C) The requirement for submittal of data from one or more of the 
test vehicles may be waived if data have been submitted previously for 
all of the engine ratings and variants.
    (iii) Evaluation requirements. (A) The evaluation must demonstrate 
the ability of the OBD system on the selected test vehicle to detect a 
malfunction, activate the MIL, and, where applicable, store an 
appropriate DTC readable by a scan tool when a malfunction is present 
and the monitoring conditions have been satisfied for each individual 
monitor required by this section. For model years 2013 and later, the 
evaluation must demonstrate the ability of the OBD system on the 
selected test vehicle to detect a malfunction, activate the MIL, and, 
where applicable, store an appropriate DTC readable by a SAE J1978 or 
SAE J1939 (both as specified in paragraph (k)(1) of this section) scan 
tool when a malfunction is present and the monitoring conditions have 
been satisfied for each individual monitor required by this section.
    (B) The evaluation must verify that the malfunction of any component 
used to enable another OBD monitor but that does not itself result in 
MIL activation (e.g., fuel level sensor) will not inhibit the ability of 
other OBD monitors to detect malfunctions properly.
    (C) The evaluation must verify that the software used to track the 
numerator and denominator for the purpose of determining in-use 
monitoring frequency increments as required by paragraph (d)(2) of this 
section.
    (D) Malfunctions may be implanted mechanically or simulated 
electronically, but internal onboard computer hardware or software 
changes shall not be used to simulate malfunctions. For monitors that 
are required to indicate a malfunction before emissions exceed an 
emission threshold, manufacturers are not required to use malfunctioning 
components/systems set exactly at their malfunction criteria limits. 
Emission testing is not required to confirm that the malfunction is 
detected before the appropriate emission thresholds are exceeded.
    (E) The manufacturer must submit a proposed test plan for approval 
prior to performing evaluation testing. The test

[[Page 532]]

plan must identify the method used to induce a malfunction for each 
monitor.
    (F) If the demonstration of a specific monitor cannot be reasonably 
performed without causing physical damage to the test vehicle (e.g., 
onboard computer internal circuit malfunctions), the manufacturer may 
omit the specific demonstration.
    (G) For evaluation of test vehicles selected in accordance with 
paragraph (j)(2)(ii) of this section, the manufacturer is not required 
to demonstrate monitors that were demonstrated prior to certification as 
required in paragraph (l) of this section.
    (iv) The manufacturer must submit a report of the results of all 
testing conducted as required by paragraph (j)(2) of this section. The 
report must identify the method used to induce a malfunction in each 
monitor, the MIL activation status, and the DTC(s) stored.
    (3) Verification of in-use monitoring performance ratios. (i) The 
manufacturer must collect and report in-use monitoring performance data 
representative of production vehicles (i.e., engine rating and chassis 
application combination). The manufacturer must collect and report the 
data to the Administrator within 12 months after the first production 
vehicle was first introduced into commerce.
    (ii) The manufacturer must separate production vehicles into the 
monitoring performance groups and submit data that represents each of 
these groups. The groups shall be based on the following criteria:
    (A) Emission control system architecture. All engines that use the 
same or similar emissions control system architecture (e.g., EGR with 
DPF and SCR; EGR with DPF and NOX adsorber; EGR with DPF-
only) and associated monitoring system would be in the same emission 
architecture category.
    (B) Vehicle application type. Within an emission architecture 
category, engines shall be separated into one of three vehicle 
application types: Engines intended primarily for line-haul chassis 
applications, engines intended primarily for urban delivery chassis 
applications, and all other engines.
    (iii) The manufacturer may use an alternative grouping method to 
collect representative data. To do so, the manufacturer must show that 
the alternative groups include production vehicles using similar 
emission controls, OBD strategies, monitoring condition calibrations, 
and vehicle application driving/usage patterns such that they are 
expected to have similar in-use monitoring performance. The manufacturer 
will still be required to submit one set of data for each of the 
alternative groups.
    (iv) For each monitoring performance group, the data must include 
all of the in-use performance tracking data (i.e., all numerators, 
denominators, the general denominator, and the ignition cycle counter), 
the date the data were collected, the odometer reading, the VIN, and the 
calibration ID. For model years 2013 and later, for each monitoring 
performance group, the data must include all of the in-use performance 
tracking data reported through SAE J1979 or SAE J1939 (both as specified 
in paragraph (k)(1) of this section; i.e., all numerators, denominators, 
the general denominator, and the ignition cycle counter), the date the 
data were collected, the odometer reading, the VIN, and the calibration 
ID.
    (v) The manufacturer must submit a plan to the Administrator that 
details the types of production vehicles in each monitoring performance 
group, the number of vehicles per group to be sampled, the sampling 
method, the timeline to collect the data, and the reporting format. The 
plan must provide for effective collection of data from, at least, 15 
vehicles per monitoring performance group and provide for data that 
represent a broad range of temperature conditions. The plan shall not, 
by design, exclude or include specific vehicles in an attempt to collect 
data only from vehicles expected to have the highest in-use performance 
ratios.
    (vi) The 12 month deadline for reporting may be extended to 18 
months if the manufacturer can show that the delay is justified. In such 
a case, an interim report of progress to date must be submitted within 
the 12 month deadline.
    (k) Standardization requirements--(1) Reference materials. The 
following documents are incorporated by reference, see Sec.86.1. 
Anyone may inspect copies at

[[Page 533]]

the U.S. EPA or at the National Archives and Records Administration 
(NARA). For information on the availability of this material at U.S. 
EPA, NARA, or the standard making bodies directly, refer to Sec.86.1.

    (x) ISO 15765-4:2005(E), January 15, 2005.
    (2) Diagnostic connector. For model years 2010 through 2012, the 
manufacturer defined data link connector must be accessible to a trained 
service technician. For model years 2013 and later, a standard data link 
connector conforming to SAE J1962 (as specified in paragraph (k)(1) of 
this section) or SAE J1939-13 (as specified in paragraph (k)(1) of this 
section) specifications (except as provided for in paragraph (k)(2)(iii) 
if this section) must be included in each vehicle.
    (i) For model years 2013 and later, the connector must be located in 
the driver's side foot-well region of the vehicle interior in the area 
bound by the driver's side of the vehicle and the driver's side edge of 
the center console (or the vehicle centerline if the vehicle does not 
have a center console) and at a location no higher than the bottom of 
the steering wheel when in the lowest adjustable position. The connector 
shall not be located on or in the center console (i.e., neither on the 
horizontal faces near the floor-mounted gear selector, parking brake 
lever, or cup-holders nor on the vertical faces near the car stereo, 
climate system, or navigation system controls). The location of the 
connector shall be capable of being easily identified and accessed 
(e.g., to connect an off-board tool). For vehicles equipped with a 
driver's side door, the connector must be identified and accessed easily 
by someone standing (or ``crouched'') on the ground outside the driver's 
side of the vehicle with the driver's side door open. The Administrator 
may approve an alternative location upon request from the manufacturer. 
In all cases, the installation position of the connector must be both 
identified and accessed easily by someone standing outside the vehicle 
and protected from accidental damage during normal vehicle use.
    (ii) For model years 2013 and later, if the connector is covered, 
the cover must be removable by hand without the use of any tools and be 
labeled ``OBD'' to aid technicians in identifying the location of the 
connector. Access to the diagnostic connector shall not require opening 
or the removal of any storage accessory (e.g., ashtray, coinbox). The 
label must clearly identify that the connector is located behind the 
cover and is consistent with language and/or symbols commonly used in 
the automobile and/or heavy truck industry.
    (iii) For model years 2013 and later, if the ISO 15765-4:2005(E) (as 
specified in paragraph (k)(1) of this section) communication protocol is 
used for the required OBD standardized functions, the connector must 
meet the ``Type A'' specifications of SAE J1962 (as specified in 
paragraph (k)(1) of this section). Any pins in the connector that 
provide electrical power must be properly fused to protect the integrity 
and usefulness of the connector for diagnostic purposes and shall not 
exceed 20.0 Volts DC regardless of the nominal vehicle system or battery 
voltage (e.g., 12V, 24V, 42V).
    (iv) For model years 2013 and later, if the SAE J1939 (as specified 
in paragraph (k)(1) of this section) protocol is used for the required 
OBD standardized functions, the connector must meet the specifications 
of SAE J1939-13 (as specified in paragraph (k)(1) of this section). Any 
pins in the connector that provide electrical power must be properly 
fused to protect the integrity and usefulness of the connector for 
diagnostic purposes.
    (v) For model years 2013 and later, the manufacturer may equip 
engines/vehicles with additional diagnostic connectors for manufacturer-
specific purposes (i.e., purposes other than the required OBD 
functions). However, if the additional connector conforms to

[[Page 534]]

the ``Type A'' specifications of SAE J1962 (as specified in paragraph 
(k)(1) of this section) or the specifications of SAE J1939-13 (as 
specified in paragraph (k)(1) of this section) and is located in the 
vehicle interior near the required connector as described in this 
paragraph (k)(2), the connector(s) must be labeled clearly to identify 
which connector is used to access the standardized OBD information 
required by paragraph (k) of this section.
    (3) Communications to a scan tool. For model years 2013 and later, 
all OBD control modules (e.g., engine, auxiliary emission control 
module) on a single vehicle must use the same protocol for communication 
of required emission-related messages from on-board to off-board network 
communications to a scan tool meeting SAE J1978 (as specified in 
paragraph (k)(1) of this section) specifications or designed to 
communicate with an SAE J1939 (as specified in paragraph (k)(1) of this 
section) network. Engine manufacturers shall not alter normal operation 
of the engine emission control system due to the presence of off-board 
test equipment accessing information required by this paragraph (k). The 
OBD system must use one of the following standardized protocols:
    (i) ISO 15765-4:2005(E) (as specified in paragraph (k)(1) of this 
section). All required emission-related messages using this protocol 
must use a 500 kbps baud rate.
    (ii) SAE J1939 (as specified in paragraph (k)(1) of this section). 
This protocol may only be used on vehicles with diesel engines.
    (4) Required emission related functions. The following functions 
must be implemented and must be accessible by, at a minimum, a 
manufacturer scan tool. For model years 2013 and later, the following 
standardized functions must be implemented in accordance with the 
specifications in SAE J1979 (as specified in paragraph (k)(1) of this 
section) or SAE J1939 (as specified in paragraph (k)(1) of this section) 
to allow for access to the required information by a scan tool meeting 
SAE J1978 (as specified in paragraph (k)(1) of this section) 
specifications or designed to communicate with an SAE J1939 (as 
specified in paragraph (k)(1) of this section) network:
    (i) Ready status. The OBD system must indicate, in accordance with 
SAE J1979 or SAE J1939-73 (both as specified in paragraph (k)(1) of this 
section) specifications for model years 2013 and later, ``complete'' or 
``not complete'' for each of the installed monitored components and 
systems identified in paragraphs (g), (h) with the exception of (h)(4), 
and (i)(3) of this section. All components or systems identified in 
paragraphs (h)(1), (h)(2), or (i)(3) of this section that are monitored 
continuously must always indicate ``complete.'' Components or systems 
that are not subject to being monitored continuously must immediately 
indicate ``complete'' upon the respective monitor(s) being executed 
fully and determining that the component or system is not 
malfunctioning. A component or system must also indicate ``complete'' 
if, after the requisite number of decisions necessary for determining 
MIL status has been executed fully, the monitor indicates a malfunction 
of the component or system. The status for each of the monitored 
components or systems must indicate ``not complete'' whenever diagnostic 
memory has been cleared or erased by a means other than that allowed in 
paragraph (b) of this section. Normal vehicle shut down (i.e., key-off/
engine-off) shall not cause the status to indicate ``not complete.''
    (A) The manufacturer may request that the ready status for a monitor 
be set to indicate ``complete'' without the monitor having completed if 
monitoring is disabled for a multiple number of drive cycles due to the 
continued presence of extreme operating conditions (e.g., cold ambient 
temperatures, high altitudes). Any such request must specify the 
conditions for monitoring system disablement and the number of drive 
cycles that would pass without monitor completion before ready status 
would be indicated as ``complete.''
    (B) For the evaporative system monitor, the ready status must be set 
in accordance with this paragraph (k)(4)(i) when both the functional 
check of the purge valve and, if applicable, the leak detection monitor 
of the hole size specified in paragraph

[[Page 535]]

(h)(7)(ii)(B) of this section indicate that they are complete.
    (C) If the manufacturer elects to indicate ready status through the 
MIL in the key-on/engine-off position as provided for in paragraph 
(b)(1)(iii) of this section, the ready status must be indicated in the 
following manner: If the ready status for all monitored components or 
systems is ``complete,'' the MIL shall remain continuously activated in 
the key-on/engine-off position for at least 10-20 seconds. If the ready 
status for one or more of the monitored components or systems is ``not 
complete,'' after at least 5 seconds of operation in the key-on/engine-
off position with the MIL activated continuously, the MIL shall blink 
once per second for 5-10 seconds. The data stream value for MIL status 
as required in paragraph (k)(4)(ii) of this section must indicate 
``commanded off'' during this sequence unless the MIL has also been 
``commanded on'' for a detected malfunction.
    (ii) Data stream. For model years 2010 through 2012, the following 
signals must be made available on demand through the data link 
connector. For model years 2013 and later, the following signals must be 
made available on demand through the standardized data link connector in 
accordance with SAE J1979 or SAE J1939 (both as specified in paragraph 
(k)(1) of this section) specifications. The actual signal value must 
always be used instead of a limp home value. Data link signals may 
report an error state or other predefined status indicator if they are 
defined for those signals in the SAE J1979 or SAE J1939 (both as 
specified in paragraph (k)(1) of this section) specifications.
    (A) For gasoline engines. (1) Calculated load value, engine coolant 
temperature, engine speed, vehicle speed, and time elapsed since engine 
start.
    (2) Absolute load, fuel level (if used to enable or disable any 
other monitors), barometric pressure (directly measured or estimated), 
engine control module system voltage, and commanded equivalence ratio.
    (3) Number of stored MIL-on DTCs, catalyst temperature (if directly 
measured or estimated for purposes of enabling the catalyst monitor(s)), 
monitor status (i.e., disabled for the rest of this drive cycle, 
complete this drive cycle, or not complete this drive cycle) since last 
engine shut-off for each monitor used for ready status, distance 
traveled (or engine run time for engines not using vehicle speed 
information) while MIL activated, distance traveled (or engine run time 
for engines not using vehicle speed information) since DTC memory last 
erased, and number of warm-up cycles since DTC memory last erased, OBD 
requirements to which the engine is certified (e.g., California OBD, EPA 
OBD, European OBD, non-OBD) and MIL status (i.e., commanded-on or 
commanded-off).
    (B) For diesel engines. (1) Calculated load (engine torque as a 
percentage of maximum torque available at the current engine speed), 
driver's demand engine torque (as a percentage of maximum engine 
torque), actual engine torque (as a percentage of maximum engine 
torque), reference engine maximum torque, reference maximum engine

of this section) within parameter group number (PGN) 65251 for engine 
configuration), engine coolant temperature, engine oil temperature (if 
used for emission control or any OBD monitors), engine speed, and time 
elapsed since engine start.
    (2) Fuel level (if used to enable or disable any other monitors), 
vehicle speed (if used for emission control or any OBD monitors), 
barometric pressure (directly measured or estimated), and engine control 
module system voltage.

the rest of this drive cycle, complete this drive cycle, or not complete 
this drive cycle) since last engine shut-off for each monitor used for 
ready status, distance traveled (or engine run time for engines not 
using vehicle speed information) while MIL activated, distance traveled 
(or engine run time for engines not using vehicle speed information) 
since DTC memory last erased, number of warm-up cycles since DTC memory 
last erased, OBD requirements to which the engine is certified (e.g., 
California OBD, EPA OBD, European

[[Page 536]]

OBD, non-OBD), and MIL status (i.e., commanded-on or commanded-off).
    (4) NOX NTE control area status (i.e., inside control 
area, outside control area, inside manufacturer-specific NOX 
NTE carve-out area, or deficiency active area) and PM NTE control area 
status (i.e., inside control area, outside control area, inside 
manufacturer-specific PM NTE carve-out area, or deficiency active area).
    (5) For purposes of the calculated load and torque parameters in 
paragraph (k)(4)(ii)(B)(1) of this section, manufacturers must report 
the most accurate values that are calculated within the applicable 
electronic control unit (e.g., the engine control module). Most 
accurate, in this context, must be of sufficient accuracy, resolution, 
and filtering to be used for the purposes of in-use emission testing 
with the engine still in a vehicle (e.g., using portable emission 
measurement equipment).
    (C) For all engines so equipped. (1) Absolute throttle position,

position, and glow plug lamp status.
    (2) Oxygen sensor output, air/fuel ratio sensor output, 
NOX sensor output, and evaporative system vapor pressure.
    (iii) Freeze frame. (A) For model years 2010 through 2012, ``Freeze 
frame'' information required to be stored pursuant to paragraphs 
(b)(2)(iv), (h)(1)(iv)(D), and (h)(2)(vi) of this section must be made 
available on demand through the data link connector. For model years 
2013 and later, ``Freeze frame'' information required to be stored 
pursuant to paragraphs (b)(2)(iv), (h)(1)(iv)(D), and (h)(2)(vi) of this 
section must be made available on demand through the standardized data 
link connector in accordance with SAE J1979 or SAE J1939-73 (both as 
specified in paragraph (k)(1) of this section) specifications.
    (B) ``Freeze frame'' conditions must include the DTC that caused the 
data to be stored along with all of the signals required in paragraphs 
(k)(4)(ii)(A)(1) and (k)(4)(ii)(B)(1) of this section. Freeze frame 
conditions must also include all of the signals required on the engine 
in paragraphs (k)(4)(ii)(A)(2) and (k)(4)(ii)(B)(2) of this section, and 
paragraph (k)(4)(ii)(C)(1) of this section that are used for diagnostic 
or control purposes in the specific monitor or emission-critical 
powertrain control unit that stored the DTC.
    (C) Only one frame of data is required to be recorded. For model 
years 2010 through 2012, the manufacturer may choose to store additional 
frames provided that at least the required frame can be read by, at a 
minimum, a manufacturer scan tool. For model years 2013 and later, the 
manufacturer may choose to store additional frames provided that at 
least the required frame can be read by a scan tool meeting SAE J1978 
(as specified in paragraph (k)(1) of this section) specifications or 
designed to communicate with an SAE J1939 (as specified in paragraph 
(k)(1) of this section) network.

[[Page 537]]

    (iv) Diagnostic trouble codes. (A) For model years 2010 through 
2012, For all monitored components and systems, any stored pending, MIL-
on, and previous-MIL-on DTCs must be made available through the 
diagnostic connector. For model years 2013 and later, all monitored 
components and systems, any stored pending, MIL-on, and previous-MIL-on 
DTCs must be made available through the diagnostic connector in a 
standardized format in accordance with SAE J1939 (as specified in 
paragraph (k)(1) of this section) or ISO 15765-4:2005(E) (as specified 
in paragraph (k)(1) of this section) specifications; standardized DTCs 
conforming to the applicable standardized specifications must be 
employed.
    (B) The stored DTC must, to the extent possible, pinpoint the 
probable cause of the malfunction or potential malfunction. To the 
extent feasible, the manufacturer must use separate DTCs for every 
monitor where the monitor and repair procedure or probable cause of the 
malfunction is different. In general, rationality and functional checks 
must use different DTCs than the respective circuit integrity checks. 
Additionally, to the extent possible, input component circuit integrity 
checks must use different DTCs for distinct malfunctions (e.g., out-of-
range low, out-of-range high, open circuit).
    (C) The manufacturer must use appropriate standard-defined DTCs 
whenever possible. With Administrator approval, the manufacturer may use 
manufacturer-defined DTCs in accordance with the applicable standard's 
specifications. To do so, the manufacturer must be able to show a lack 
of available standard-defined DTCs, uniqueness of the monitor or 
monitored component, expected future usage of the monitor or component, 
and estimated usefulness in providing additional diagnostic and repair 
information to service technicians. Manufacturer-defined DTCs must be 
used in a consistent manner (i.e., the same DTC shall not be used to 
represent two different failure modes) across a manufacturer's entire 
product line.
    (D) For model years 2010 through 2012, a pending or MIL-on DTC (as 
required in paragraphs (g) through (i) of this section) must be stored 
and available to, at a minimum, a manufacturer scan tool within 10 
seconds after a monitor has determined that a malfunction or potential 
malfunction has occurred. A permanent DTC must be stored and available 
to, at a minimum, a manufacturer scan tool no later than the end of an 
ignition cycle in which the corresponding MIL-on DTC that caused MIL 
activation has been stored. For model years 2013 and later, a pending or 
MIL-on DTC (as required in paragraphs (g) through (i) of this section) 
must be stored and available to an SAE J1978 (as specified in paragraph 
(k)(1) of this section) or SAE J1939 (as specified in paragraph (k)(1) 
of this section) scan tool within 10 seconds after a monitor has 
determined that a malfunction or potential malfunction has occurred. A 
permanent DTC must be stored and available to an SAE J1978 (as specified 
in paragraph (k)(1) of this section) or SAE J1939 (as specified in 
paragraph (k)(1) of this section) scan tool no later than the end of an 
ignition cycle in which the corresponding MIL-on DTC that caused MIL 
activation has been stored.
    (E) For model years 2010 through 2012, pending DTCs for all 
components and systems (including those monitored continuously and non-
continuously) must be made available through the diagnostic connector. 
For model years 2013 and later, pending DTCs for all components and 
systems (including those monitored continuously and non-continuously) 
must be made available through the diagnostic connector in accordance 
with the applicable standard's specifications. For all model years, a 
manufacturer using alternative statistical protocols for MIL activation 
as allowed in paragraph (b)(2)(iii) of this section must submit the 
details of their protocol for setting pending DTCs. The protocol must 
be, overall, equivalent to the requirements of this paragraph 
(k)(4)(iv)(E) and provide service technicians with a quick and accurate 
indication of a potential malfunction.
    (F) For model years 2010 through 2012, permanent DTC for all 
components and systems must be made available through the diagnostic 
connector

[[Page 538]]

in a format that distinguishes permanent DTCs from pending DTCs, MIL-on 
DTCs, and previous-MIL-on DTCs. A MIL-on DTC must be stored as a 
permanent DTC no later than the end of the ignition cycle and 
subsequently at all times that the MIL-on DTC is commanding the MIL on. 
For model years 2013 and later, permanent DTC for all components and 
systems must be made available through the diagnostic connector in a 
standardized format that distinguishes permanent DTCs from pending DTCs, 
MIL-on DTCs, and previous-MIL-on DTCs. A MIL-on DTC must be stored as a 
permanent DTC no later than the end of the ignition cycle and 
subsequently at all times that the MIL-on DTC is commanding the MIL on. 
For all model years, permanent DTCs must be stored in non-volatile 
random access memory (NVRAM) and shall not be erasable by any scan tool 
command or by disconnecting power to the on-board computer. Permanent 
DTCs must be erasable if the engine control module is reprogrammed and 
the ready status described in paragraph (k)(4)(i) of this section for 
all monitored components and systems are set to ``not complete.'' The 
OBD system must have the ability to store a minimum of four current MIL-
on DTCs as permanent DTCs in NVRAM. If the number of MIL-on DTCs 
currently commanding activation of the MIL exceeds the maximum number of 
permanent DTCs that can be stored, the OBD system must store the 
earliest detected MIL-on DTC as permanent DTC. If additional MIL-on DTCs 
are stored when the maximum number of permanent DTCs is already stored 
in NVRAM, the OBD system shall not replace any existing permanent DTC 
with the additional MIL-on DTCs.
    (v) Test results. (A) For model years 2010 through 2012 and except 
as provided for in paragraph (k)(4)(v)(G) of this section, for all 
monitored components and systems identified in paragraphs (g) and (h) of 
this section, results of the most recent monitoring of the components 
and systems and the test limits established for monitoring the 
respective components and systems must be stored and available through 
the data link. For model years 2013 and later and except as provided for 
in paragraph (k)(4)(v)(G) of this section, for all monitored components 
and systems identified in paragraphs (g) and (h) of this section, 
results of the most recent monitoring of the components and systems and 
the test limits established for monitoring the respective components and 
systems must be stored and available through the data link in accordance 
with the standardized format specified in SAE J1979 (as specified in 
paragraph (k)(1) of this section) for engines using the ISO 15765-
4:2005(E) (as specified in paragraph (k)(1) of this section) protocol or 
SAE J1939 (as specified in paragraph (k)(1) of this section).
    (B) The test results must be reported such that properly functioning 
components and systems (e.g., ``passing'' systems) do not store test 
values outside of the established test limits. Test limits must include 
both minimum and maximum acceptable values and must be defined so that a 
test result equal to either test limit is a ``passing'' value, not a 
``failing'' value.
    (C) For model years 2013 and later, the test results must be 
standardized such that the name of the monitored component (e.g., 
catalyst bank 1) can be identified by a generic scan tool and the test 
results and limits can be scaled and reported by a generic scan tool 
with the appropriate engineering units.
    (D) The test results must be stored until updated by a more recent 
valid test result or the DTC memory of the OBD system computer is 
cleared. Upon DTC memory being cleared, test results reported for 
monitors that have not yet completed with valid test results since the 
last time the fault memory was cleared must report values of zero for 
the test result and test limits.
    (E) All test results and test limits must always be reported and the 
test results must be stored until updated by a more recent valid test 
result or the DTC memory of the OBD system computer is cleared.
    (F) The OBD system must store and report unique test results for 
each separate monitor.
    (G) The requirements of this paragraph (k)(4)(v) do not apply to 
continuous fuel system monitoring, cold start

[[Page 539]]

emission reduction strategy monitoring, and continuous circuit 
monitoring.
    (vi) Software calibration identification (CAL ID). On all engines, a 
single software calibration identification number (CAL ID) for each 
monitor or emission critical control unit(s) must be made available 
through, for model years 2010 through 2012, the data link connector or, 
for model years 2013 and later, the standardized data link connector in 
accordance with the SAE J1979 or SAE J1939 (both as specified in 
paragraph (k)(1) of this section) specifications. A unique CAL ID must 
be used for every emission-related calibration and/or software set 
having at least one bit of different data from any other emission-
related calibration and/or software set. Control units coded with 
multiple emission or diagnostic calibrations and/or software sets must 
indicate a unique CAL ID for each variant in a manner that enables an 
off-board device to determine which variant is being used by the engine. 
Control units that use a strategy that will result in MIL activation if 
the incorrect variant is used (e.g., control units that contain variants 
for manual and automatic transmissions but will activate the MIL if the 
selected variant does not match the type of transmission mated to the 
engine) are not required to use unique CAL IDs. Manufacturers may 
request Administrator approval to respond with more than one CAL ID per 
diagnostic or emission critical control unit. Administrator approval of 
the request shall be based on the method used by the manufacturer to 
ensure each control unit will respond to a scan tool with the CAL IDs in 
order of highest to lowest priority with regards to areas of the 
software most critical to emission and OBD system performance.
    (vii) Software calibration verification number (CVN). (A) All 
engines must use an algorithm to calculate a single calibration 
verification number (CVN) that verifies the on-board computer software 
integrity for each monitor or emission critical control unit that is 
electronically reprogrammable. The CVN must be made available through, 
for model years 2010 through 2012, the data link connector or, for model 
years 2013 and later, the standardized data link connector in accordance 
with the SAE J1979 or SAE J1939 (both as specified in paragraph (k)(1) 
of this section) specifications. The CVN must indicate whether the 
emission-related software and/or calibration data are valid and 
applicable for the given vehicle and CAL ID. For systems having more 
than one CAL ID as allowed under paragraph (k)(4)(vi) of this section, 
one CVN must be made available for each CAL ID and must be output to a 
scan tool in the same order as the corresponding CAL IDs. For 2010 
through 2012, manufacturers may use a default value for the CVN if their 
emissions critical powertrain control modules are not programmable in 
the field. For all years, manufacturers may use a default value for the 
CVN if their emissions critical powertrain control modules are one-time 
programmable or masked read-only memory. Any default CVN shall be 
00000000 for systems designed in accordance with the SAE J1979 (as 
specified in paragraph (k)(1) of this section) specifications, and 
FFFFFFFFh for systems designed in accordance with the SAE J1939 (as 
specified in paragraph (k)(1) of this section) specifications.
    (B) The CVN algorithm used to calculate the CVN must be of 
sufficient complexity that the same CVN is difficult to achieve with 
modified calibration values.
    (C) The CVN must be calculated at least once per ignition cycle and 
stored until the CVN is subsequently updated. Except for immediately 
after a reprogramming event or a non-volatile memory clear or for the 
first 30 seconds of engine operation after a volatile memory clear or 
battery disconnect, the stored value must be made available through, for 
model years 2010 through 2012, the data link connector to, at a minimum, 
a manufacturer scan tool or, for model years 2013 and later, the data 
link connector to a generic scan tool in accordance with SAE J1979 or 
SAE J1939 (both as specified in paragraph (k)(1) of this section) 
specifications. For model years 2010 through 2012, the stored CVN value 
shall not be erased when DTC memory is erased or during normal vehicle 
shut down (i.e., key-off/engine-off). For model years 2013 and later, 
the stored CVN value

[[Page 540]]

shall not be erased when DTC memory is erased by a generic scan tool in 
accordance with SAE J1979 or SAE J1939 (both as specified in paragraph 
(k)(1) of this section) specifications or during normal vehicle shut 
down (i.e., key-off/engine-off).
    (D) For model years 2013 and later, the CVN and CAL ID combination 
information must be available for all engines/vehicles in a standardized 
electronic format that allows for off-board verification that the CVN is 
valid and appropriate for a specific vehicle and CAL ID.
    (viii) Vehicle identification number (VIN). (A) For model years 2010 
through 2012, all vehicles must have the vehicle identification number 
(VIN) available through the data link connector to, at a minimum, a 
manufacturer scan tool Only one electronic control unit per vehicle may 
report the VIN to a scan tool. For model years 2013 and later, all 
vehicles must have the vehicle identification number (VIN) available in 
a standardized format through the standardized data link connector in 
accordance with SAE J1979 or SAE J1939 (both as specified in paragraph 
(k)(1) of this section) specifications. Only one electronic control unit 
per vehicle may report the VIN to an SAE J1978 or SAE J1939 (both as 
specified in paragraph (k)(1) of this section) scan tool.
    (B) If the VIN is reprogrammable, all emission-related diagnostic 
information identified in paragraph (k)(4)(ix)(A) of this section must 
be erased in conjunction with reprogramming of the VIN.
    (ix) Erasure of diagnostic information. (A) For purposes of this 
paragraph (k)(4)(ix), ``emission-related diagnostic information'' 
includes all of the following: ready status as required by paragraph 
(k)(4)(i) of this section; data stream information as required by 
paragraph (k)(4)(ii) of this section including the number of stored MIL-
on DTCs, distance traveled while MIL activated, number of warm-up cycles 
since DTC memory last erased, and distance traveled since DTC memory 
last erased; freeze frame information as required by paragraph 
(k)(4)(iii) of this section; pending, MIL-on, and previous-MIL-on DTCs 
as required by paragraph (k)(4)(iv) of this section; and, test results 
as required by paragraph (k)(4)(v) of this section.
    (B) For all engines, the emission-related diagnostic information 
must be erased if commanded by any scan tool and may be erased if the 
power to the on-board computer is disconnected. If any of the emission-
related diagnostic information is commanded to be erased by any scan 
tool, all emission-related diagnostic information must be erased from 
all diagnostic or emission critical control units. The OBD system shall 
not allow a scan tool to erase a subset of the emission-related 
diagnostic information (e.g., the OBD system shall not allow a scan tool 
to erase only one of three stored DTCs or only information from one 
control unit without erasing information from the other control 
unit(s)).
    (5) In-use performance ratio tracking requirements. (i) For each 
monitor required in paragraphs (g) through (i) of this section to 
separately report an in-use performance ratio, manufacturers must 
implement software algorithms to, for model years 2010 through 2012, 
report a numerator and denominator or, for model years 2013 and later, 
report a numerator and denominator in the standardized format specified 
in this paragraph (k)(5) in accordance with the SAE J1979 or SAE J1939 
(both as specified in paragraph (k)(1) of this section) specifications.
    (ii) For the numerator, denominator, general denominator, and 
ignition cycle counters required by paragraph (e) of this section, the 
following numerical value specifications apply:
    (A) Each number shall have a minimum value of zero and a maximum 
value of 65,535 with a resolution of one.
    (B) Each number shall be reset to zero only when a non-volatile 
random access memory (NVRAM) reset occurs (e.g., reprogramming event) 
or, if the numbers are stored in keep-alive memory (KAM), when KAM is 
lost due to an interruption in electrical power to the control unit 
(e.g., battery disconnect). Numbers shall not be reset to zero under any 
other circumstances including when a scan tool command to clear DTCs or 
reset KAM is received.
    (C) To avoid overflow problems, if either the numerator or 
denominator for

[[Page 541]]

a specific component reaches the maximum value of 65,535 2, both numbers shall be divided by two before either is 
incremented again.
    (D) To avoid overflow problems, if the ignition cycle counter 
reaches the maximum value of 65,535 2, the 
ignition cycle counter shall rollover and increment to zero on the next 
ignition cycle.
    (E) To avoid overflow problems, if the general denominator reaches 
the maximum value of 65,535 2, the general 
denominator shall rollover and increment to zero on the next drive cycle 
that meets the general denominator definition.
    (F) If a vehicle is not equipped with a component (e.g., oxygen 
sensor bank 2, secondary air system), the corresponding numerator and 
denominator for that specific component shall always be reported as 
zero.
    (iii) For the ratio required by paragraph (e) of this section, the 
following numerical value specifications apply:
    (A) The ratio shall have a minimum value of zero and a maximum value 
of 7.99527 with a resolution of 0.000122.
    (B) The ratio for a specific component shall be considered to be 
zero whenever the corresponding numerator is equal to zero and the 
corresponding denominator is not zero.
    (C) The ratio for a specific component shall be considered to be the 
maximum value of 7.99527 if the corresponding denominator is zero or if 
the actual value of the numerator divided by the denominator exceeds the 
maximum value of 7.99527.
    (6) Engine run time tracking requirements. (i) For all gasoline and 
diesel engines, the manufacturer must implement software algorithms to, 
for model years 2010 through 2012, track and report individually or, for 
model years 2013 and later, track and report individually in a 
standardized format the amount of time the engine has been operated in 
the following conditions:
    (A) Total engine run time.
    (B) Total idle run time (with ``idle'' defined as accelerator pedal 
released by the driver, engine speed less than or equal to 200 rpm above 
normal warmed-up idle (as determined in the drive position for vehicles 
equipped with an automatic transmission) or vehicle speed less than or 
equal to one mile per hour, and power take-off not active).
    (C) Total run time with power take off active.
    (ii) For each counter specified in paragraph (k)(6)(i) of this 
section, the following numerical value specifications apply:
    (A) Each number shall be a four-byte value with a minimum value of 
zero, a resolution of one second per bit, and an accuracy of ten seconds per drive cycle.
    (B) Each number shall be reset to zero only when a non-volatile 
memory reset occurs (e.g., reprogramming event). Numbers shall not be 
reset to zero under any other circumstances including when a scan tool 
(generic or enhanced) command to clear fault codes or reset KAM is 
received.
    (C) To avoid overflow problems, if any of the individual counters 
reach the maximum value, all counters shall be divided by two before any 
are incremented again.
    (D) For model years 2010 through 2012, the counters shall be made 
available to, at a minimum, a manufacturer scan tool and may be rescaled 
when transmitted from a resolution of one second per bit to no more than 
three minutes per bit. For model years 2013 and later, the counters 
shall be made available to a generic scan tool in accordance with the 
SAE J1979 or SAE J1939 (both as specified in paragraph (k)(1) of this 
section) specifications and may be rescaled when transmitted, if 
required by the SAE specifications, from a resolution of one second per 
bit to no more than three minutes per bit.
    (7) For 2019 and subsequent model year alternative-fueled engines 
derived from a diesel-cycle engine, a manufacturer may meet the 
standardization requirements of paragraph (k) of this section that are 
applicable to diesel engines rather than the requirements applicable to 
gasoline engines.
    (l) Monitoring system demonstration requirements for certification--
(1) General. (i) The manufacturer must submit emissions test data from 
one or more durability demonstration test engines (test engines).
    (ii) The Administrator may approve other demonstration protocols if 
the manufacturer can provide comparable

[[Page 542]]

assurance that the malfunction criteria are chosen based on meeting the 
malfunction criteria requirements and that the timeliness of malfunction 
detection is within the constraints of the applicable monitoring 
requirements.
    (iii) For flexible fuel engines capable of operating on more than 
one fuel or fuel combinations, the manufacturer must submit a plan for 
providing emission test data. The plan must demonstrate that testing 
will represent properly the expected in-use fuel or fuel combinations.
    (2) Selection of test engines. (i) Prior to submitting any 
applications for certification for a model year, the manufacturer must 
notify the Administrator regarding the planned engine families and 
engine ratings within each family for that model year. The Administrator 
will select the engine family(ies) and the specific engine rating within 
the engine family(ies) that the manufacturer shall use as demonstration 
test engines. The selection of test vehicles for production evaluation 
testing as specified in paragraph (j)(2) of this section may take place 
during this selection process.
    (ii) For model years 2010 through 2012. The manufacturer must 
provide emissions test data from the OBD parent rating as defined in 
paragraph (o)(1) of this section.
    (iii) For model years 2013 and later. (A) A manufacturer certifying 
one to five engine families in a given model year must provide emissions 
test data for a single test engine from one engine rating. A 
manufacturer certifying six to ten engine families in a given model year 
must provide emissions test data for a single test engine from two 
different engine ratings. A manufacturer certifying eleven or more 
engine families in a given model year must provide emissions test data 
for a single test engine from three different engine ratings. A 
manufacturer may forego submittal of test data for one or more of these 
test engines if data have been submitted previously for all of the 
engine ratings and/or if all requirements for certification carry-over 
from one model year to the next are satisfied.
    (B) For a given model year, a manufacturer may elect to provide 
emissions data for test engines from more engine ratings than required 
by paragraph (l)(2)(iii)(A) of this section. For each additional engine 
rating tested in that given model year, the number of engine ratings 
required for testing in one future model year will be reduced by one.
    (iv) For the test engine, the manufacturer must use an engine 
(excluding aftertreatment devices) aged for a minimum of 125 hours 
fitted with exhaust aftertreatment emission controls aged to be 
representative of useful life aging. In the event that an accelerated 
aging procedure is used, the manufacturer is required to submit a 
description of the accelerated aging process and/or supporting data or 
use the accelerated aging procedure used for emission certification 
deterioration factor generation. The process and/or data must 
demonstrate that deterioration of the exhaust aftertreatment emission 
controls is stabilized sufficiently such that it represents emission 
control performance at the end of the useful life.
    (3) Required testing. Except as otherwise described in this 
paragraph (l)(3), the manufacturer must perform single malfunction 
testing based on the applicable test with the components/systems set at 
their malfunction criteria limits as determined by the manufacturer for 
meeting the emissions thresholds required in paragraphs (g), (h), and 
(i) of this section.
    (i) Required testing for diesel-fueled/compression ignition 
engines--(A) Fuel system. The manufacturer must perform a separate test 
for each malfunction limit established by the manufacturer for the fuel 
system parameters (e.g., fuel pressure, injection timing) specified in 
paragraphs (g)(1)(ii)(A) through (g)(1)(ii)(C) and/or (g)(1)(ii)(D) of 
this section, if applicable, of this section. When performing a test for 
a specific parameter, the fuel system must be operating at the 
malfunction criteria limit for the applicable parameter only. All other 
parameters must be operating with normal characteristics. In conducting 
the fuel system demonstration tests, the manufacturer may use computer 
modifications to cause the fuel system to operate at the malfunction 
limit if the manufacturer can demonstrate that the computer 
modifications produce test results

[[Page 543]]

equivalent to an induced hardware malfunction.
    (B) Engine misfire. For model years 2013 and later, the manufacturer 
must perform a test at the malfunction limit established by the 
manufacturer for the monitoring required by paragraph (g)(2)(ii)(B) of 
this section.
    (C) EGR system. The manufacturer must perform a separate test for 
each malfunction limit established by the manufacturer for the EGR 
system parameters (e.g., low flow, high flow, slow response) specified 
in paragraphs (g)(3)(ii)(A) through (g)(3)(ii)(C) and in (g)(3)(ii)(E) 
of this section. In conducting the EGR system slow response 
demonstration tests, the manufacturer may use computer modifications to 
cause the EGR system to operate at the malfunction limit if the 
manufacturer can demonstrate that the computer modifications produce 
test results equivalent to an induced hardware malfunction.
    (D) Turbo boost control system. The manufacturer must perform a 
separate test for each malfunction limit established by the manufacturer 
for the turbo boost control system parameters (e.g., underboost, 
overboost, response) specified in paragraphs (g)(4)(ii)(A) through 
(g)(4)(ii)(C) and in (g)(4)(ii)(E) of this section.
    (E) NMHC catalyst. The manufacturer must perform a separate test for 
each monitored NMHC catalyst(s). The catalyst(s) being evaluated must be 
deteriorated to the applicable malfunction limit established by the 
manufacturer for the monitoring required by paragraph (g)(5)(ii)(A) of 
this section and using methods established by the manufacturer in 
accordance with paragraph (l)(7) of this section. For each monitored 
NMHC catalyst(s), the manufacturer must also demonstrate that the OBD 
system will detect a catalyst malfunction with the catalyst at its 
maximum level of deterioration (i.e., the substrate(s) completely 
removed from the catalyst container or ``empty'' can). Emissions data 
are not required for the empty can demonstration.
    (F) NOX catalyst. The manufacturer must perform a separate test for 
each monitored NOX catalyst(s) (e.g., SCR catalyst). The catalyst(s) 
being evaluated must be deteriorated to the applicable malfunction 
criteria established by the manufacturer for the monitoring required by 
paragraphs (g)(6)(ii)(A) and (g)(6)(ii)(B) of this section and using 
methods established by the manufacturer in accordance with paragraph 
(l)(7) of this section. For each monitored NOX catalyst(s), the 
manufacturer must also demonstrate that the OBD system will detect a 
catalyst malfunction with the catalyst at its maximum level of 
deterioration (i.e., the substrate(s) completely removed from the 
catalyst container or ``empty'' can). Emissions data are not required 
for the empty can demonstration.
    (G) NOX adsorber. The manufacturer must perform a test using a NOX 
adsorber(s) deteriorated to the applicable malfunction limit established 
by the manufacturer for the monitoring required by paragraph 
(g)(7)(ii)(A) of this section. The manufacturer must also demonstrate 
that the OBD system will detect a NOX adsorber malfunction with the NOX 
adsorber at its maximum level of deterioration (i.e., the substrate(s) 
completely removed from the container or ``empty'' can). Emissions data 
are not required for the empty can demonstration.
    (H) Diesel particulate filter. The manufacturer must perform a 
separate test using a DPF deteriorated to the applicable malfunction 
limits established by the manufacturer for the monitoring required by 
paragraph (g)(8)(ii)(A) and (g)(8)(ii)(B) of this section. For systems 
using the optional DPF monitoring provision of paragraph (g)(8)(ii)(A) 
of this section, the manufacturer must perform a separate test using a 
DPF modified in a manner approved by the Administrator (e.g., drilling 
of wallflow channel end plugs, drilling of through holes, etc.) and 
testing at each of the nine test points specified in paragraph 
(g)(8)(ii)(A) of this section. The manufacturer must also demonstrate 
that the OBD system will detect a DPF malfunction with the DPF at its 
maximum level of deterioration (i.e., the filter(s) completely removed 
from the filter container or ``empty'' can). Emissions data are not 
required for the empty can demonstration.
    (I) Exhaust gas sensor. The manufacturer must perform a separate 
test for

[[Page 544]]

each malfunction limit established by the manufacturer for the 
monitoring required in paragraphs (g)(9)(ii)(A), (g)(9)(iii)(A), and 
(g)(9)(iv)(A) of this section. When performing a test, all exhaust gas 
sensors used for the same purpose (e.g., for the same feedback control 
loop, for the same control feature on parallel exhaust banks) must be 
operating at the malfunction criteria limit for the applicable parameter 
only. All other exhaust gas sensor parameters must be operating with 
normal characteristics.
    (J) VVT system. The manufacturer must perform a separate test for 
each malfunction limit established by the manufacturer for the 
monitoring required in paragraphs (g)(10)(ii)(A) and (g)(10)(ii)(B) of 
this section. In conducting the VVT system demonstration tests, the 
manufacturer may use computer modifications to cause the VVT system to 
operate at the malfunction limit if the manufacturer can demonstrate 
that the computer modifications produce test results equivalent to an 
induced hardware malfunction.
    (K) For each of the testing requirements of this paragraph (l)(3)(i) 
of this section, if the manufacturer has established that only a 
functional check is required because no failure or deterioration of the 
specific tested system could result in an engine's emissions exceeding 
the applicable emissions thresholds, the manufacturer is not required to 
perform a demonstration test; however, the manufacturer is required to 
provide the data and/or engineering analysis used to determine that only 
a functional test of the system(s) is required.
    (ii) Required testing for gasoline-fueled/spark-ignition engines--
(A) Fuel system. For engines with adaptive feedback based on the primary 
fuel control sensor(s), the manufacturer must perform a test with the 
adaptive feedback based on the primary fuel control sensor(s) at the 
rich limit(s) and a test at the lean limit(s) established by the 
manufacturer as required by paragraph (h)(1)(ii)(A) of this section to 
detect a malfunction before emissions exceed applicable emissions 
thresholds. For engines with feedback based on a secondary fuel control 
sensor(s) and subject to the malfunction criteria in paragraph 
(h)(1)(ii)(A) of this section, the manufacturer must perform a test with 
the feedback based on the secondary fuel control sensor(s) at the rich 
limit(s) and a test at the lean limit(s) established by the manufacturer 
as required by paragraph (h)(1)(ii)(A) of this section to detect a 
malfunction before emissions exceed the applicable emissions thresholds. 
For other fuel metering or control systems, the manufacturer must 
perform a test at the criteria limit(s). For purposes of fuel system 
testing as required by this paragraph (l)(3)(ii)(A), the malfunction(s) 
induced may result in a uniform distribution of fuel and air among the 
cylinders. Non uniform distribution of fuel and air used to induce a 
malfunction shall not cause misfire. In conducting the fuel system 
demonstration tests, the manufacturer may use computer modifications to 
cause the fuel system to operate at the malfunction limit. To do so, the 
manufacturer must be able to demonstrate that the computer modifications 
produce test results equivalent to an induced hardware malfunction.
    (B) Misfire. The manufacturer must perform a test at the malfunction 
criteria limit specified in paragraph (h)(2)(ii)(B) of this section.
    (C) EGR system. The manufacturer must perform a test at each flow 
limit calibrated to the malfunction criteria specified in paragraphs 
(h)(3)(ii)(A) and (h)(3)(ii)(B) of this section.
    (D) Cold start emission reduction strategy. The manufacturer must 
perform a test at the malfunction criteria for each component monitored 
according to paragraph (h)(4)(ii)(A) of this section.
    (E) Secondary air system. The manufacturer must perform a test at 
each flow limit calibrated to the malfunction criteria specified in 
paragraphs (h)(5)(ii)(A) and (h)(5)(ii)(B) of this section.
    (F) Catalyst. The manufacturer must perform a test using a catalyst 
system deteriorated to the malfunction criteria specified in paragraph 
(h)(6)(ii) of this section using methods established by the manufacturer 
in accordance with paragraph (l)(7)(ii) of this section.

[[Page 545]]

The manufacturer must also demonstrate that the OBD system will detect a 
catalyst system malfunction with the catalyst system at its maximum 
level of deterioration (i.e., the substrate(s) completely removed from 
the catalyst container or ``empty'' can). Emission data are not required 
for the empty can demonstration.
    (G) Exhaust gas sensor. The manufacturer must perform a test with 
all primary exhaust gas sensors used for fuel control simultaneously 
possessing a response rate deteriorated to the malfunction criteria 
limit specified in paragraph (h)(8)(ii)(A) of this section. The 
manufacturer must also perform a test for any other primary or secondary 
exhaust gas sensor parameter under parargraphs (h)(8)(ii)(A) and 
(h)(8)(iii)(A) of this section that can cause engine emissions to exceed 
the applicable emissions thresholds (e.g., shift in air/fuel ratio at 
which oxygen sensor switches, decreased amplitude). When performing 
additional test(s), all primary and secondary (if applicable) exhaust 
gas sensors used for emission control must be operating at the 
malfunction criteria limit for the applicable parameter only. All other 
primary and secondary exhaust gas sensor parameters must be operating 
with normal characteristics.
    (H) VVT system. The manufacturer must perform a test at each target 
error limit and slow response limit calibrated to the malfunction 
criteria specified in paragraphs (h)(9)(ii)(A) and (h)(9)(ii)(B) of this 
section. In conducting the VVT system demonstration tests, the 
manufacturer may use computer modifications to cause the VVT system to 
operate at the malfunction limit. To do so, the manufacturer must be 
able to demonstrate that the computer modifications produce test results 
equivalent to an induced hardware malfunction.
    (I) For each of the testing requirements of this paragraph 
(l)(3)(ii), if the manufacturer has established that only a functional 
check is required because no failure or deterioration of the specific 
tested system could cause an engine's emissions to exceed the applicable 
emissions thresholds, the manufacturer is not required to perform a 
demonstration test; however the manufacturer is required to provide the 
data and/or engineering analyses used to determine that only a 
functional test of the system(s) is required.
    (iii) Required testing for all engines. (A) Other emission control 
systems. The manufacturer must conduct demonstration tests for all other 
emission control components (e.g., hydrocarbon traps, adsorbers) 
designed and calibrated to a malfunction limit based on an emissions 
threshold based on the requirements of paragraph (i)(4) of this section.
    (B) For each of the testing requirements of paragraph (l)(3)(iii)(A) 
of this section, if the manufacturer has established that only a 
functional check is required because no failure or deterioration of the 
specific tested system could result in an engine's emissions exceeding 
the applicable emissions thresholds, the manufacturer is not required to 
perform a demonstration test; however, the manufacturer is required to 
provide the data and/or engineering analysis used to determine that only 
a functional test of the system(s) is required.
    (iv) The manufacturer may electronically simulate deteriorated 
components but shall not make any engine control unit modifications when 
performing demonstration tests unless approved by the Administrator. All 
equipment necessary to duplicate the demonstration test must be made 
available to the Administrator upon request.
    (4) Testing protocol--(i) Preconditioning. The manufacturer must use 
an applicable cycle for preconditioning test engines prior to conducting 
each of the emission tests required by paragraph (l)(3) of this section. 
The manufacturer may perform a single additional preconditioning cycle, 
identical to the initial one, after a 20-minute hot soak but must 
demonstrate that such an additional cycle is necessary to stabilize the 
emissions control system. A practice of requiring a cold soak prior to 
conducting preconditioning cycles is not permitted.
    (ii) Test sequence. (A) The manufacturer must set individually each 
system or component on the test engine at the malfunction criteria limit 
prior to

[[Page 546]]

conducting the applicable preconditioning cycle(s). If a second 
preconditioning cycle is permitted in accordance with paragraph 
(l)(4)(i) of this section, the manufacturer may adjust the system or 
component to be tested before conducting the second preconditioning 
cycle. The manufacturer shall not replace, modify, or adjust the system 
or component after the last preconditioning cycle has been completed.
    (B) After preconditioning, the test engine must be operated over the 
applicable cycle to allow for the initial detection of the tested system 
or component malfunction. This test cycle may be omitted from the 
testing protocol if it is unnecessary. If required by the monitoring 
strategy being tested, a cold soak may be performed prior to conducting 
this test cycle.
    (C) The test engine must then be operated over the applicable 
exhaust emissions test.
    (iii) A manufacturer required to test more than one test engine 
according to paragraph (l)(2)(iii) of this section may use internal 
calibration sign-off test procedures (e.g., forced cool downs, less 
frequently calibrated emission analyzers) instead of official test 
procedures to obtain the emission test data required by this paragraph 
(l) of this section for all but one of the required test engines. The 
manufacturer may elect this option if the data from the alternative test 
procedure are representative of official emissions test results. A 
manufacturer using this option is still responsible for meeting the 
malfunction criteria specified in paragraphs (g) through (i) of this 
section if and when emissions tests are performed in accordance with 
official test procedures.
    (iv) The manufacturer may request approval to use an alternative 
testing protocol for demonstration of MIL activation if the engine 
dynamometer emission test cycle does not allow all of a given monitor's 
enable conditions to be satisfied. The manufacturer may request the use 
of an alternative engine dynamometer test cycle or the use of chassis 
testing to demonstrate proper MIL activation. To do so, the manufacturer 
must demonstrate the technical necessity for using an alternative test 
cycle and the degree to which the alternative test cycle demonstrates 
that in-use operation with the malfunctioning component will result in 
proper MIL activation.
    (5) Evaluation protocol. Full OBD engine ratings, as defined by 
paragraph (o)(1) of this section, shall be evaluated according to the 
following protocol:
    (i) For all tests conducted as required by paragraph (l) of this 
section, the MIL must activate before the end of the first engine start 
portion of the applicable test.
    (ii) If the MIL activates prior to emissions exceeding the 
applicable malfunction criteria limits specified in paragraphs (g) 
through (i), no further demonstration is required. With respect to the 
misfire monitor demonstration test, if the manufacturer has elected to 
use the minimum misfire malfunction criteria of one percent as allowed 
in paragraphs (g)(2)(ii)(B), if applicable, and (h)(2)(ii)(B) of this 
section, no further demonstration is required provided the MIL activates 
with engine misfire occurring at the malfunction criteria limit.
    (iii) If the MIL does not activate when the system or component is 
set at its malfunction criteria limit(s), the criteria limit(s) or the 
OBD system is not acceptable.
    (A) Except for testing of the catalyst or DPF system, if the MIL 
first activates after emissions exceed the applicable malfunction 
criteria specified in paragraphs (g) through (i) of this section, the 
test engine shall be retested with the tested system or component 
adjusted so that the MIL will activate before emissions exceed the 
applicable malfunction criteria specified in paragraphs (g) through (i) 
of this section. If the component cannot be so adjusted because an 
alternative fuel or emission control strategy is used when a malfunction 
is detected (e.g., open loop fuel control used after an oxygen sensor 
malfunction is detected), the test engine shall be retested with the 
component adjusted to the worst acceptable limit (i.e., the applicable 
OBD monitor indicates that the component is performing at or slightly 
better than the malfunction criteria limit). When tested with the 
component so adjusted, the MIL must not activate during the test and the 
engine emissions must be

[[Page 547]]

below the applicable malfunction criteria specified in paragraphs (g) 
through (i) of this section.
    (B) In testing the catalyst or DPF system, if the MIL first 
activates after emissions exceed the applicable emissions threshold(s) 
specified in paragraphs (g) and (h), the tested engine shall be retested 
with a less deteriorated catalyst or DPF system (i.e., more of the 
applicable engine out pollutants are converted or trapped). For the OBD 
system to be approved, testing shall be continued until the MIL 
activates with emissions below the applicable thresholds of paragraphs 
(g) and (h) of this section, or the MIL activates with emissions within 
a range no more than 20 percent below the applicable emissions 
thresholds and 10 percent or less above those emissions thresholds.
    (iv) If an OBD system is determined to be unacceptable by the 
criteria of this paragraph (l)(5) of this section, the manufacturer may 
recalibrate and retest the system on the same test engine. In such a 
case, the manufacturer must confirm, by retesting, that all systems and 
components that were tested prior to the recalibration and are affected 
by it still function properly with the recalibrated OBD system.
    (6) Confirmatory testing. (i) The Administrator may perform 
confirmatory testing to verify the emission test data submitted by the 
manufacturer as required by this paragraph (l) of this section comply 
with its requirements and the malfunction criteria set forth in 
paragraphs (g) through (i) of this section. Such confirmatory testing is 
limited to the test engine(s) required by paragraph (l)(2) of this 
section.
    (ii) To conduct this confirmatory testing, the Administrator may 
install appropriately deteriorated or malfunctioning components (or 
simulate them) in an otherwise properly functioning test engine of an 
engine rating represented by the demonstration test engine in order to 
test any of the components or systems required to be tested by paragraph 
(l) of this section. The manufacturer shall make available, if 
requested, an engine and all test equipment (e.g., malfunction 
simulators, deteriorated components) necessary to duplicate the 
manufacturer's testing. Such a request from the Administrator shall 
occur within six months of reviewing and approving the demonstration 
test engine data submitted by the manufacturer for the specific engine 
rating.
    (7) Catalyst aging--(i) Diesel catalysts. For purposes of 
determining the catalyst malfunction limits for the monitoring required 
by paragraphs (g)(5)(ii)(A), (g)(5)(ii)(B), and (g)(6)(ii)(A) of this 
section, where those catalysts are monitored individually, the 
manufacturer must use a catalyst deteriorated to the malfunction 
criteria using methods established by the manufacturer to represent real 
world catalyst deterioration under normal and malfunctioning engine 
operating conditions. For purposes of determining the catalyst 
malfunction limits for the monitoring required by paragraphs 
(g)(5)(ii)(A), (g)(5)(ii)(B), and (g)(6)(ii)(A) of this section, where 
those catalysts are monitored in combination with other catalysts, the 
manufacturer must submit their catalyst system aging and monitoring plan 
to the Administrator as part of their certification documentation 
package. The plan must include the description, emission control 
purpose, and location of each component, the monitoring strategy for 
each component and/or combination of components, and the method for 
determining the applicable malfunction criteria including the 
deterioration/aging process.
    (ii) Gasoline catalysts. For the purposes of determining the 
catalyst system malfunction criteria in paragraph (h)(6)(ii) of this 
section, the manufacturer must use a catalyst system deteriorated to the 
malfunction criteria using methods established by the manufacturer to 
represent real world catalyst deterioration under normal and 
malfunctioning operating conditions. The malfunction criteria must be 
established by using a catalyst system with all monitored and 
unmonitored (downstream of the sensor utilized for catalyst monitoring) 
catalysts simultaneously deteriorated to the malfunction criteria except 
for those engines that use fuel shutoff to prevent over-fueling during 
engine misfire conditions. For such engines, the malfunction criteria 
must be established by

[[Page 548]]

using a catalyst system with all monitored catalysts simultaneously 
deteriorated to the malfunction criteria while unmonitored catalysts 
shall be deteriorated to the end of the engine's useful life.
    (m) Certification documentation requirements. (1) When submitting an 
application for certification of an engine, the manufacturer must submit 
the following documentation. If any of the items listed here are 
standardized for all of the manufacturer's engines, the manufacturer 
may, for each model year, submit one set of documents covering the 
standardized items for all of its engines.
    (i) For the required documentation that is not standardized across 
all engines, the manufacturer may be allowed to submit documentation for 
certification from one engine that is representative of other engines. 
All such engines shall be considered to be part of an OBD certification 
documentation group. To represent the OBD group, the chosen engine must 
be certified to the most stringent emissions standards and OBD 
monitoring requirements and cover all of the emissions control devices 
for the engines in the group and covered by the submitted documentation. 
Such OBD groups must be approved in advance of certification.
    (ii) Upon approval, one or more of the documentation requirements of 
this paragraph (m) of this section may be waived or modified if the 
information required is redundant or unnecessarily burdensome to 
generate.
    (iii) To the extent possible, the certification documentation must 
use SAE J1930 (as specified in paragraph (k)(1) of this section) or SAE 
J2403 (as specified in paragraph (k)(1) of this section) terms, 
abbreviations, and acronyms as specified in paragraph (k)(1) of this 
section.
    (2) Unless otherwise specified, the following information must be 
submitted as part of the certification application and prior to 
receiving a certificate.
    (i) A description of the functional operation of the OBD system 
including a complete written description for each monitoring strategy

representations of the monitoring strategy shall be included where 
necessary to adequately describe the information.
    (ii) A table including the following information for each monitored

    (I) Criteria used for determining out-of-range values and input 
component rationality checks.
    (iii) Whenever possible, the table required by paragraph (m)(2)(ii) 
of this section shall use the following engineering units:
    (A) Degrees Celsius for all temperature criteria.
    (B) KiloPascals (KPa) for all pressure criteria related to manifold 
or atmospheric pressure.
    (C) Grams (g) for all intake air mass criteria.

(k)(1) of this section) Mode/Service $06, SAE J1939 (as specified in 
paragraph (k)(1) of this section) Diagnostic Message 8 (DM8)) stored 
during the test, and a description of the modified or deteriorated 
components used for malfunction simulation with respect to the 
demonstration tests specified in paragraph (l) of this section. The 
freeze frame data are not required for engines termed ``Extrapolated 
OBD'' engines.
    (vi) For gasoline engines, data supporting the misfire monitor, 
including:
    (A) The established percentage of misfire that can be tolerated 
without damaging the catalyst over the full range of engine speed and

(h)(2)(ii)(B) of this section, one cylinder continuously misfiring, and 
paired cylinders continuously misfiring.
    (C) Data identifying all disablement of misfire monitoring that 
occurs during the FTP. For every disablement that occurs during the 
cycles, the data shall identify: when the disablement occurred relative 
to the driver's trace, the number of engine revolutions during which 
each disablement was present, and which disable condition documented in 
the certification application caused the disablement.
    (D) Manufacturers are not required to use the durability 
demonstration engine to collect the misfire data required by paragraph 
(m)(2)(vi) of this section.
    (vii) Data supporting the limit for the time between engine starting 
and attaining the designated heating temperature for after-start heated 
catalyst systems.
    (viii) Data supporting the criteria used to detect a malfunction of 
the fuel system, EGR system, boost pressure control system, catalyst, 
NOX adsorber, DPF, cold start emission reduction strategy, 
secondary air, evaporative system, VVT system, exhaust gas sensors, and 
other emission controls that causes emissions to exceed the applicable 
malfunction criteria specified in paragraphs (g) through (i) of this 
section. For diesel engine monitors required by paragraphs (g) and (i) 
of this section that are required to indicate a malfunction before 
emissions exceed an emission threshold based on any applicable standard 
(e.g., 2.5 times any of the applicable standards), the test cycle and 
standard determined by the manufacturer to be the most stringent for 
each applicable monitor in accordance with paragraph (f)(1) of this 
section.
    (ix) A list of all electronic powertrain input and output signals 
(including those not monitored by the OBD system) that identifies which 
signals are monitored by the OBD system. For input and output signals 
that are monitored as comprehensive components, the listing shall also 
identify the specific diagnostic trouble code for each malfunction 
criteria (e.g., out-of-range low, out-of-range high, open circuit, 
rationality low, rationality high).
    (x) A written description of all parameters and conditions necessary 
to begin closed-loop/feedback control of emission control systems (e.g., 
fuel system, boost pressure, EGR flow, SCR reductant delivery, DPF 
regeneration, fuel system pressure).
    (xi) A written identification of the communication protocol utilized 
by each engine for communication with a scan tool (model years 2010 
through

[[Page 550]]

2012) or an SAE J1978 or SAE J1939 (both as specified in paragraph 
(k)(1) of this section) scan tool (model years 2013 and later).
    (xii) For model years 2013 and later, a pictorial representation or 
written description of the diagnostic connector location including any 
covers or labels.
    (xiii) A written description of the method used by the manufacturer

and/or hose connections.
    (xiv) Build specifications provided to engine purchasers or chassis 
manufacturers detailing all specifications or limitations imposed on the 
engine purchaser relevant to OBD requirements or emissions compliance 
(e.g., cooling system heat rejection rates, allowable MIL locations, 
connector location specifications). A description of the method or 
copies of agreements used to ensure engine purchasers or chassis 
manufacturers will comply with the OBD and emissions relevant build 
specifications (e.g., signed agreements, required audit/evaluation 
procedures).
    (xv) Any other information determined by the Administrator to be 
necessary to demonstrate compliance with the requirements of this 
section.
    (3) In addition to the documentation required by paragraphs (m)(1) 
and (m)(2) of this section, a manufacturer making use of paragraph 
(a)(5) of this section must submit the following information with their 
application for certification.
    (i) A detailed description of how the OBD system meets the intent of 
Sec.86.010-18.
    (ii) A detailed description of why the manufacturer has chosen not 
to design the OBD system to meet the requirements of Sec.86.010-18 and 
has instead designed the OBD system to meet the applicable California 
OBD requirements.
    (iii) A detailed description of any deficiencies granted by the 
California staff and any concerns raised by California staff. A copy of 
a California Executive Order alone will not be considered acceptable 
toward meeting this requirement. This description shall also include, to 
the extent feasible, a plan with timelines for resolving deficiencies 
and/or concerns.
    (n) Deficiencies. (1) Upon application by the manufacturer, the 
Administrator may accept an OBD system as compliant even though specific 
requirements are not fully met. Such compliances without meeting 
specific requirements, or deficiencies, will be granted only if 
compliance is infeasible or unreasonable considering such factors as, 
but not limited to: Technical feasibility of the given monitor and lead 
time and production cycles including phase-in or phase-out of engines or 
vehicle designs and programmed upgrades of computers. Unmet requirements 
shall not be carried over from the previous model year except where 
unreasonable hardware or software modifications are necessary to correct 
the deficiency, and the manufacturer has demonstrated an acceptable 
level of effort toward compliance as determined by the Administrator. 
Furthermore, EPA will not accept any deficiency requests that include 
the complete lack of a major diagnostic monitor (``major'' diagnostic 
monitors being those for exhaust aftertreatment devices, oxygen sensor, 
air-fuel ratio sensor, NOX sensor, engine misfire, 
evaporative leaks, and diesel EGR, if equipped), with the possible 
exception of the special provisions for alternative fueled engines. For 
alternative fueled heavy-duty engines (e.g., natural gas, liquefied 
petroleum gas, methanol, ethanol), manufacturers may request the 
Administrator to waive specific monitoring requirements of this section 
for which monitoring may not be reliable with respect to the use of the 
alternative fuel. At a minimum, alternative fuel engines must be 
equipped with an OBD system meeting OBD requirements to the extent 
feasible as approved by the Administrator.
    (2) In the event the manufacturer seeks to carry-over a deficiency 
from a past model year to the current model year, the manufacturer must 
re-apply for approval to do so. In considering the request to carry-over 
a deficiency, the Administrator shall consider the manufacturer's 
progress towards correcting the deficiency. The Administrator may not 
allow manufacturers to

[[Page 551]]

carry over monitoring system deficiencies for more than two model years 
unless it can be demonstrated that substantial engine hardware 
modifications and additional lead time beyond two years are necessary to 
correct the deficiency.
    (3) A deficiency shall not be granted retroactively (i.e., after the 
engine has been certified).
    (o) Implementation schedule. Except as specifically provided for in 
this paragraph (o) for small volume manufacturers and alternative fueled 
engines, the requirements of this section must be met according to the 
following provisions:
    (1) For model years 2010 through 2012--(i) Full OBD. The 
manufacturer must implement an OBD system meeting the applicable 
requirements of Sec.86.010-18 on one engine rating within one engine 
family of the manufacturer's product line. This ``Full OBD'' rating will 
be known as the ``OBD parent'' rating. The OBD parent rating must be 
chosen, unless otherwise approved by the Administrator, as the rating 
having the highest weighted projected U.S. sales within the engine 
family having the highest weighted projected U.S. sales, with U.S. sales 
being weighted by the useful life of the engine rating.
    (ii) Extrapolated OBD. For all other engine ratings within the 
engine family from which the OBD parent rating has been selected, the 
manufacturer must implement an OBD system meeting the applicable 
requirements of Sec.86.010-18 except that the OBD system is not 
required to detect a malfunction prior to exceeding the emission 
thresholds shown in Table 1 of paragraph (g) and Table 2 of paragraph 
(h) of this section. These ``Extrapolated OBD'' engines will be know as 
the ``OBD child'' ratings. On these OBD child ratings, rather than 
detecting a malfunction prior to exceeding the emission thresholds, the 
manufacturer must submit a plan for Administrator review and approval 
that details the engineering evaluation the manufacturer will use to 
establish the malfunction criteria for the OBD child ratings. The plan 
must demonstrate both the use of good engineering judgment in 
establishing the malfunction criteria, and robust detection of 
malfunctions, including consideration of differences of base engine, 
calibration, emission control components, and emission control 
strategies.
    (iii) Engine families other than those from which the parent and 
child ratings have been selected, are not subject to the requirements of 
this section.
    (iv) Small volume manufacturers, as defined in Sec.86.094-14(b)(1) 
and (2) and as determined using 2010 model year sales, are exempt from 
the requirements of this Sec.86.010-18, unless model year 2011 or 
model year 2012 sales exceed 20,000 units.
    (v) Engines certified as alternative fueled engines are exempt from 
the requirements of this Sec.86.010-18.
    (2) For model years 2013 through 2015--(i) OBD groups. The 
manufacturer shall define one or more OBD groups to cover all engine 
ratings in all engine families. The manufacturer must submit a grouping 
plan for Administrator review and approval detailing the OBD groups and 
the engine families and engine ratings within each group for a given 
model year.
    (ii) Full OBD. (A) For all model year 2010 through 2012 ``Full OBD'' 
and ``Extrapolated OBD'' engine ratings, the manufacturer must implement 
an OBD system meeting the applicable requirements of this section.
    (B) On one engine rating within each of the manufacturer's OBD 
groups, the manufacturer must implement an OBD system meeting the 
applicable requirements of this section. These ``Full OBD'' ratings will 
be known as the ``OBD parent'' ratings. The OBD parent rating for each 
OBD group shall be chosen, unless otherwise approved by the 
Administrator, as the rating having the highest weighted projected U.S. 
sales within the OBD group, with U.S. sales being weighted by the useful 
life of the engine rating.
    (iii) Extrapolated OBD. For all other engine ratings within each OBD 
group, the manufacturer must implement an OBD system meeting the 
requirements of this section except that the OBD system is not required 
to detect a malfunction prior to exceeding the emission thresholds shown 
in Table 1 of paragraph (g) and Table 2 of paragraph (h) of this 
section. These extrapolated OBD engines will be know as the ``OBD

[[Page 552]]

child'' ratings. On these OBD child ratings, rather than detecting a 
malfunction prior to exceeding the emission thresholds, the manufacturer 
must submit a plan for Administrator review and approval that details 
the engineering evaluation the manufacturer will use to establish the 
malfunction criteria for the OBD child ratings. The plan must 
demonstrate both the use of good engineering judgment in establishing 
the malfunction criteria, and robust detection of malfunctions, 
including consideration of differences of base engine, calibration, 
emission control components, and emission control strategies.
    (iv) Engines certified as alternative fueled engines shall meet, to 
the extent feasible, the requirements specified in paragraph (i)(3) of 
this Sec.86.010-18. Additionally, such engines shall monitor the 
NOX aftertreatment system on engines so equipped and detect a 
malfunction if:
    (A) The NOX aftertreatment system has no detectable 
amount of NOX aftertreatement capability (i.e., 
NOX catalyst conversion or NOX adsorption).
    (B) The NOX aftertreatment substrate is completely 
destroyed, removed, or missing.
    (C) The NOX aftertreatment assembly is replaced with a 
straight pipe.
    (3) For model years 2016 through 2018--(i) OBD groups. The 
manufacturer shall define one or more OBD groups to cover all engine 
ratings in all engine families. The manufacturer must submit a grouping 
plan for Administrator review and approval detailing the OBD groups and 
the engine families and engine ratings within each group for a given 
model year.
    (ii) Full OBD. The manufacturer must implement an OBD system meeting 
the applicable requirements of this section on all engine ratings in all 
engine families.
    (iii) Engines certified as alternative fueled engines shall meet, to 
the extent feasible, the requirements specified in paragraph (i)(3) of 
this Sec.86.010-18. Additionally, such engines shall monitor the 
NOX aftertreatment system on engines so equipped and detect a 
malfunction if:
    (A) The NOX aftertreatment system has no detectable 
amount of NOX aftertreatement capability (i.e., 
NOX catalyst conversion or NOX adsorption).
    (B) The NOX aftertreatment substrate is completely 
destroyed, removed, or missing.
    (C) The NOX aftertreatment assembly is replaced with a 
straight pipe.
    (4) For model years 2019 and later. (i) The manufacturer must 
implement an OBD system meeting the applicable requirements of Sec.
86.010-18 on all engines.
    (p) In-use compliance standards. For monitors required to indicate a 
malfunction before emissions exceed a certain emission threshold (e.g., 
2.5 times any of the applicable standards):
    (1) For model years 2010 through 2012. (i) On the full OBD rating 
(i.e., the parent rating) as defined in paragraph (o)(1) of this 
section, separate in-use emissions thresholds shall apply. These 
thresholds are determined by doubling the applicable thresholds as shown 
in Table 1 of paragraph (g) and Table 2 of paragraph (h) of this 
section. The resultant thresholds apply only in-use and do not apply for 
certification or selective enforcement auditing.
    (ii) The extrapolated OBD ratings (i.e., the child ratings) as 
defined in paragraph (o)(1) of this section shall not be evaluated 
against emissions levels for purposes of OBD compliance in-use.
    (iii) Only the test cycle and standard determined and identified by 
the manufacturer at the time of certification in accordance with 
paragraph (f) of this section as the most stringent shall be used for 
the purpose of determining OBD system noncompliance in-use.
    (iv) An OBD system shall not be considered noncompliant solely due 
to a failure or deterioration mode of a monitored component or system 
that could not have been reasonably foreseen to occur by the 
manufacturer.
    (2) For model years 2013 through 2015. (i) On the full OBD ratings 
as defined in paragraph (o)(2) of this section, separate in-use 
emissions thresholds shall apply. These thresholds are determined by 
doubling the applicable thresholds as shown in Table 1 of paragraph (g) 
and Table 2 of paragraph (h) of this section. The resultant thresholds 
apply

[[Page 553]]

only in-use and do not apply for certification or selective enforcement 
auditing.
    (ii) The extrapolated OBD ratings as defined in paragraph (o)(2) of 
this section shall not be evaluated against emissions levels for 
purposes of OBD compliance in-use.
    (iii) Only the test cycle and standard determined and identified by 
the manufacturer at the time of certification in accordance with 
paragraph (f) of this section as the most stringent shall be used for 
the purpose of determining OBD system noncompliance in-use.
    (iv) For monitors subject to meeting the minimum in-use monitor 
performance ratio of 0.100 in paragraph (d)(1)(ii), the OBD system shall 
not be considered noncompliant unless a representative sample indicates 
the in-use ratio is below 0.050.
    (v) An OBD system shall not be considered noncompliant solely due to 
a failure or deterioration mode of a monitored component or system that 
could not have been reasonably foreseen to occur by the manufacturer.
    (3) For model years 2016 through 2018. (i) On the engine ratings 
tested according to (l)(2)(iii) of this section, the certification 
emissions thresholds shall apply in-use.
    (ii) On the manufacturer's remaining engine ratings, separate in-use 
emissions thresholds shall apply. These thresholds are determined by 
doubling the applicable thresholds as shown in Table 1 of paragraph (g) 
and Table 2 of paragraph (h) of this section. The resultant thresholds 
apply only in-use and do not apply for certification or selective 
enforcement auditing.
    (iii) An OBD system shall not be considered noncompliant solely due 
to a failure or deterioration mode of a monitored component or system 
that could not have been reasonably foreseen to occur by the 
manufacturer.
    (4) For model years 2019 and later. (i) On all engine ratings, the 
certification emissions thresholds shall apply in-use.
    (ii) An OBD system shall not be considered noncompliant solely due 
to a failure or deterioration mode of a monitored component or system 
that could not have been reasonably foreseen to occur by the 
manufacturer.
    (q) Optional phase-in for hybrid vehicles. This paragraph (q) 
applies for model year 2013 through 2015 engines when used with hybrid 
powertrain systems. It also applies for model year 2016 engines used 
with hybrid powertrain systems that were offered for sale prior to 
January 1, 2013, as specified in paragraph (q)(4) of this section. 
Manufacturers choosing to use the provisions of this paragraph (q) must 
submit an annual pre-compliance report to EPA for model years 2013 and 
later, as specified in paragraph (q)(5) of this section. Note that all 
hybrid powertrain systems must be fully compliant with the OBD 
requirements of this section no later than model year 2017.
    (1) If an engine-hybrid system has been certified by the California 
Air Resources Board with respect to its OBD requirements and it 
effectively meets the full OBD requirements of this section, all 
equivalent systems must meet those same requirements and may not be 
certified under this paragraph (q). For purposes of this paragraph 
(q)(1), an engine-hybrid system is considered to be equivalent to the 
certified system if it uses the same basic design (e.g. displacement) 
for the engine and primary hybrid components (see paragraph (q)(4) of 
this section). Equivalent systems may have minor hardware or calibration 
differences.
    (2) As of 2013, if an engine-hybrid system has not been certified to 
meet the full OBD requirements of this section, it must comply with the 
following requirements:
    (i) The engine in its installed configuration must meet the EMD and 
EMD + requirements in 13 CCR Sec.1971.1(d)(7.1.4) of the California 
Code of Regulations. For purposes of this paragraph (q), a given EMD 
requirement is deemed to be met if the engine's OBD system addresses the 
same function. This allowance does not apply for OBD monitors or 
diagnostics that have been modified under paragraph (q)(2)(ii) of this 
section.
    (ii) The engine-hybrid system must maintain existing OBD capability 
for engines where the same or equivalent engine has been OBD certified. 
An equivalent engine is one produced by the same engine manufacturer 
with the

[[Page 554]]

same fundamental design, but that may have hardware or calibration 
differences that do not impact OBD functionality, such as slightly 
different displacement, rated power, or fuel system. (Note that engines 
with the same fundamental design will be presumed to be equivalent 
unless the manufacturer demonstrates that the differences effectively 
preclude applying equivalent OBD systems.) Though the OBD capability 
must be maintained, it does not have to meet detection thresholds (as 
described in Tables 1 and 2 of this section) and in-use performance 
frequency requirements (as described in paragraph (d) of this section). 
A manufacturer may modify detection thresholds to prevent false 
detection, and must indicate all deviations from the originally 
certified package with engineering justification in the certification 
documentation.
    (iii) This paragraph (q)(2)(iii) applies for derivatives of hybrid 
powertrain system designs that were offered for sale prior to January 1, 
2013. Until these systems achieve full OBD certification, they must at a 
minimum maintain all fault-detection and diagnostic capability included 
on similar systems offered for sale prior to 2013. Manufacturers 
choosing to use the provisions of this paragraph (q)(2) must keep copies 
of the service manuals (and similar documents) for these previous model 
years to show the technical description of the system's fault detection 
and diagnostic capabilities.
    (iv) You must submit an annual pre-compliance report to EPA for 
model years 2013 and later, as specified in paragraph (q)(5) of this 
section.
    (3) Engine-hybrid systems may be certified to the requirements of 
paragraph (q)(2) of this section by the engine manufacturer, the hybrid 
system manufacturer, or the vehicle manufacturer. If engine 
manufacturers certify the engine hybrid system, they must provide 
detailed installation instructions. Where the engine manufacturer does 
not specifically certify its engines for use in hybrid vehicles under 
this paragraph (q), the hybrid system manufacturer and vehicle 
manufacturer must install the engine to conform to the requirements of 
this section (i.e., full OBD) or recertify under paragraph (q)(2) of 
this section.
    (4) The provisions of this paragraph (q) apply for model year 2016 
engines where you demonstrate that the hybrid powertrain system used is 
a derivative of a design that was offered for sale prior to January 1, 
2013. In this case, you may ask us to consider the original system and 
the later system to be the same model for purposes of this paragraph 
(q), unless the systems are fundamentally different. In determining 
whether such systems are derivative or fundamentally different, we will 
consider factors such as the similarity of the following:
    (i) Transmissions.
    (ii) Hybrid machines (where ``hybrid machine'' means any system that 
is the part of a hybrid vehicle system that captures energy from and 
returns energy to the powertrain).
    (iii) Hybrid architecture (such as parallel or series).
    (iv) Motor/generator size, controller/CPU (memory or inputs/
outputs), control algorithm, and batteries. This paragraph (q)(4)(iv) 
applies only if all of these are modified simultaneously.
    (5) Manufacturers choosing to use the provisions of this paragraph 
(q) must submit an annual pre-compliance report to EPA for model years 
2013 and later. Engine manufacturers must submit this report with their 
engine certification information. Hybrid manufacturers that are not 
certifying the engine-hybrid system must submit their report by June 1 
of the model year, or at the time of certification if they choose to 
certify. Include the following in the report:
    (i) A description of the manufacturer's product plans and of the 
engine-hybrid systems being certified.
    (ii) A description of activities undertaken and progress made by the 
manufacturer towards achieving full OBD certification, including 
monitoring, diagnostics, and standardization.
    (iii) For model year 2016 engines, a description of your basis for 
applying the provision of this paragraph (q) to the engines.
    (6) Manufacturers that modify the engine's diagnostic system from 
the approved configuration to be compatible with a hybrid powertrain 
system

[[Page 555]]

under this paragraph (q) must add the following compliance statement to 
the ECI label: ``for use in hybrid applications only''.

Sec.86.010-38  Maintenance instructions.

    (a) The manufacturer shall furnish or cause to be furnished to the 
purchaser of each new motor vehicle (or motor vehicle engine) subject to 
the standards prescribed in Sec.86.099-8, Sec.86.004-9, Sec.
86.004-10, or Sec.86.004-11, as applicable, written instructions for 
the proper maintenance and use of the vehicle (or engine), by the 
purchaser consistent with the provisions of Sec.86.004-25, which 
establishes what scheduled maintenance the Administrator approves as 
being reasonable and necessary.
    (1) The maintenance instructions required by this section shall be 
in clear, and to the extent practicable, nontechnical language.
    (2) The maintenance instructions required by this section shall 
contain a general description of the documentation which the 
manufacturer will require from the ultimate purchaser or any subsequent 
purchaser as evidence of compliance with the instructions.
    (b) Instructions provided to purchasers under paragraph (a) of this 
section shall specify the performance of all scheduled maintenance 
performed by the manufacturer on certification durability vehicles and, 
in cases where the manufacturer performs less maintenance on 
certification durability vehicles than the allowed limit, may specify 
the performance of any scheduled maintenance allowed under Sec.86.004-
25.
    (c) Scheduled emission-related maintenance in addition to that 
performed under Sec.86.004-25(b) may only be recommended to offset the 
effects of abnormal in-use operating conditions, except as provided in 
paragraph (d) of this section. The manufacturer shall be required to 
demonstrate, subject to the approval of the Administrator, that such 
maintenance is reasonable and technologically necessary to assure the 
proper functioning of the emission control system. Such additional 
recommended maintenance shall be clearly differentiated, in a form 
approved by the Administrator, from that approved under Sec.86.004-
25(b).
    (d) Inspections of emission-related parts or systems with 
instructions to replace, repair, clean, or adjust the parts or systems 
if necessary, are not considered to be items of scheduled maintenance 
which insure the proper functioning of the emission control system. Such 
inspections, and any recommended maintenance beyond that approved by the 
Administrator as reasonable and necessary under paragraphs (a), (b), and 
(c) of this section, may be included in the written instructions 
furnished to vehicle owners under paragraph (a) of this section: 
Provided, That such instructions clearly state, in a form approved by 
the Administrator, that the owner need not perform such inspections or 
recommended maintenance in order to maintain the emissions defect and 
emissions performance warranty or manufacturer recall liability.
    (e) The manufacturer may choose to include in such instructions an 
explanation of any distinction between the useful life specified on the 
label, and the emissions defect and emissions performance warranty 
period. The explanation must clearly state that the useful life period 
specified on the label represents the average period of use up to 
retirement or rebuild for the engine family represented by the engine 
used in the vehicle. An explanation of how the actual useful lives of 
engines used in various applications are expected to differ from the 
average useful life may be included. The explanation(s) shall be in 
clear, non-technical language that is understandable to the ultimate 
purchaser.
    (f) If approved by the Administrator, the instructions provided to 
purchasers under paragraph (a) of this section shall indicate what 
adjustments or modifications, if any, are necessary to allow the vehicle 
to meet applicable emission standards at elevations above 4,000 feet, or 
at elevations of 4,000 feet or less.
    (g) Manufacturers are subject to the service-information 
requirements of

[[Page 556]]

Sec.86.1808-01(f) beginning in the 2005 model year for manufacturers 
of heavy-duty vehicles and heavy-duty engines weighing 14,000 pounds 
gross vehicle weight (GVW) and less that are subject to the OBD 
requirements of this part.
    (h) The manufacturer shall furnish or cause to be furnished to the 
purchaser of each new motor engine subject to the standards prescribed 
in Sec.86.004-10 or Sec.86.004-11, as applicable, the following:
    (1) Instructions for all maintenance needed after the end of the 
useful life of the engine for critical emissions-related components as 
provided in Sec.86.004-25(b), including recommended practices for 
diagnosis, cleaning, adjustment, repair, and replacement of the 
component (or a statement that such component is maintenance free for 
the life of the engine) and instructions for accessing and responding to 
any emissions-related diagnostic codes that may be stored in on-board 
monitoring systems;
    (2) A copy of the engine rebuild provisions contained in Sec.
86.004-40.
    (i) Through model year 2013, the manufacturer shall furnish or cause 
to be furnished to the ultimate purchaser the following statement for 
each new diesel-fueled engine subject to the standards prescribed in 
Sec.86.007-11, as applicable: ``This engine must be operated only with 
ultra low-sulfur diesel fuel (meeting EPA specifications for highway 
diesel fuel, including a 15 ppm sulfur cap).''
    (j) The following provisions describe requirements related to 
emission control diagnostic service information for heavy-duty engines 
used in vehicles over 14,000 pounds gross vehicle weight (GVW):
    (1) Manufacturers of heavy-duty engines used in applications 
weighing more than 14,000 pounds gross vehicle weight (GVW) that are 
subject to the applicable OBD requirements of this subpart A are subject 
to the provisions of this paragraph (j) beginning in the 2010 model 
year. The provisions of this paragraph (j) apply only to those heavy-
duty engines subject to the applicable OBD requirements.
    (2) Upon Administrator approval, manufacturers of vehicles may 
alternatively comply with all service information and tool provisions 
found in Sec.86.1808-01 that are applicable to 2001 and subsequent 
model year vehicles weighing less than 14,000 pounds gross vehicle 
weight (GVW). Upon Administrator approval, manufacturers that produce 
engines for use in vehicles between 8,500 and 14,000 pounds may, for 
those engines, alternatively comply with all service information and 
tool provisions in Sec.86.010-38(j) that are applicable to 2010 and 
subsequent model year vehicles over 14,000 pounds. Implementation dates 
must comply with the service information provision dates applicable to 
engines in vehicles between 8,500 and 14,000 pounds.
    (3) General requirements. (i) Manufacturers shall furnish or cause 
to be furnished to any person engaged in the repairing or servicing of 
heavy-duty engines, or the Administrator upon request, any and all 
information needed to make use of the on-board diagnostic system and 
such other information, including instructions for making emission-
related diagnosis and repairs, including but not limited to service 
manuals, technical service bulletins, recall service information, bi-
directional control information, and training information, unless such 
information is protected by section 208(c) as a trade secret. 
Manufacturers may take steps to restrict warranty and customer assurance 
plan information used only for the purpose of providing such 
manufacturer covered repairs to only those repair locations authorized 
by the manufacturer. No such information may be withheld under section 
208(c) of the Act if that information is provided (directly or 
indirectly) by the manufacturer to franchised dealers, authorized 
service networks, or other persons engaged in the repair, diagnosing, or 
servicing of heavy-duty engines.
    (ii) Definitions. The following definitions apply for this paragraph 
(j):
    (A) Aftermarket service provider means any individual or business 
engaged in the diagnosis, service, and repair of a heavy-duty engine, 
who is not directly affiliated with a manufacturer or manufacturer 
franchised dealership, or authorized service network.
    (B) Authorized service network means a group of independent service 
and repair facilities that are recognized by engine

[[Page 557]]

manufacturers as being capable of performing repairs to factory 
specification, including warranty repair work.
    (C) Bi-directional control means the capability of a diagnostic tool 
to send messages on the data bus that temporarily overrides the module's 
control over a sensor or actuator and gives control to the diagnostic 
tool operator. Bi-directional controls do not create permanent changes 
to engine or component calibrations.
    (D) Data stream information means information (i.e., messages and 
parameters) originated within the engine by a module or intelligent 
sensors (i.e., a sensor that contains and is controlled by its own 
module) and transmitted between a network of modules and/or intelligent 
sensors connected in parallel with either one or more communication 
wires. The information is broadcast over the communication wires for use 
by the OBD system to gather information on emissions-related components 
or systems and from other engine modules that may impact emissions. For 
the purposes of this section, data stream information does not include 
engine calibration related information, or any data stream information 
from systems or modules that do not impact emissions.
    (E) Emissions-related information means any information related to 
the diagnosis, service, and repair of emissions-related components. 
Emissions-related information includes, but is not limited to, 
information regarding any system, component or part of an engine that 
controls emissions and that is part of the diagnostic strategy for an 
OBD monitor, but not limited to: The engine, the fuel system and 
ignition system; information for any system, component or part that is 
likely to impact emissions, and any other information specified by the 
Administrator to be relevant to the diagnosis and repair of an 
emissions-related problem; any other information specified by the 
Administrator to be relevant for the diagnosis and repair of an 
emissions-related failure found through an evaluation of vehicles in-use 
and after such finding has been communicated to the affected 
manufacturer(s).
    (F) Emissions-related training information means any information 
related training or instruction for the purpose of the diagnosis, 
service, and repair of emissions-related components.
    (G) Enhanced service and repair information means information which

information necessary for the completion of any emissions-related repair 
on engines that employ integral security systems.
    (H) Equipment and tool company means a registered equipment or 
software company either public or private that is engaged in, or plans 
to engage in, the manufacture of scan tool reprogramming equipment or 
software.
    (I) Generic service and repair information means information which 
is not specific for an original equipment manufacturer's brand of tools 
and equipment.
    (J) Indirect information means any information that is not 
specifically contained in the service literature, but is contained in 
items such as tools or equipment provided to franchised dealers or 
authorized service networks (or others). This includes computer or anti-
theft system initialization information necessary for the completion of 
any emissions-related repair on engines that employ integral security 
systems.
    (K) Intermediary means any individual or entity, other than an 
original equipment manufacturer, which provides service or equipment to 
aftermarket service providers.
    (L) Manufacturer franchised dealership means any service provider 
with which a manufacturer has a direct business relationship.
    (M) Recalibration means the process of downloading to an engine's 
on-board computer emissions-related revisions of on-board computer 
application software and calibration parameters with default 
configurations. Recalibration is not dependent on the use of the vehicle 
identification number (VIN) in determining vehicle configuration.
    (N) Reconfiguration means the process of enabling or adjusting 
engine features or engine parameters associated with such features to 
adapt a heavy-duty engine to a particular vehicle and/or application.

    (iv) Upon Administrator approval, implement a range of time periods 
for online access to any person specified in paragraph (j)(3)(i) of this 
section whereby the user will be able to access the site, search for the 
information, and purchase, view and print the information at a fair and 
reasonable cost as specified in paragraph (j)(8) of this section for 
each of the options. In addition, for each of the range of time periods, 
manufacturers are required to make their entire site accessible for the 
respective period of time and price. In other words, a manufacturer may 
not limit Web site access to just one make or one model.
    (v) Allow the user to search the manufacturer Web site by various 
topics including but not limited to model, model year, key words or 
phrases, etc., while allowing ready identification of the latest 
calibration. Manufacturers who do not use model year to classify their 
engines in their service information may use an alternate delineation 
such as body series. Any manufacturer utilizing this flexibility shall 
create a cross-reference to the corresponding model year and provide 
this cross-reference on the manufacturer Web site home page.
    (vi) Provide accessibility using common, readily available software 
and shall not require the use of software, hardware, viewers, or 
browsers that are not readily available to the general public. 
Manufacturers shall also provide hyperlinks to any plug-ins, viewers or

    (5) Small volume provisions for information dissemination. (i) 
Manufacturers with total annual sales of less than 5,000 engines shall 
have until July 1, 2011 to launch their individual Web sites as required 
by paragraph (j)(4) of this section.
    (ii) Manufacturers with total annual sales of less than 1,000 
engines may, in lieu of meeting the requirement of paragraph (j)(4) of 
this section, request the Administrator to approve an alternative method 
by which the required emissions-related information can be obtained by 
the persons specified in paragraph (j)(3)(i) of this section.
    (6) Required information. All information relevant to the diagnosis 
and completion of emissions-related repairs shall be posted on 
manufacturer Web sites. This excludes indirect information specified in 
paragraphs (j)(7) and (j)(13) through (j)(17) of this section. To the 
extent that this information does not already exist in some form for 
their manufacturer franchised dealerships or authorized service 
networks, manufacturers are required to develop and make available the 
information required by this section to both their manufacturer 
franchised dealerships or authorized service networks and the 
aftermarket. The required information includes, but is not limited to:
    (i) Manuals, including subsystem and component manuals developed by 
a manufacturer's third party supplier that are made available to 
manufacturer franchised dealerships or authorized service networks, 
technical service bulletins (TSBs), recall service information, 
diagrams, charts, and training materials. Informal recall service 
information such as engineering notes and/or sketches are not required 
to be made available as long as this information is not made available 
to manufacturer franchised dealerships or authorized service networks in 
the form of manuals. Manuals and other such service information from 
third party suppliers are not required to be made available in full-text 
on manufacturer Web sites as described in paragraph (j)(4) of this 
section. Rather, manufacturers must make available on the manufacturer 
Web site as required by paragraph (j)(4) of this section an index of the 
relevant information and instructions on how to order such information. 
In the alternate, a manufacturer can create a link from its Web site to 
the Web site(s) of the third party supplier.
    (ii) OBD system information which includes, but is not limited to, 
the following:
    (A) A general description of the operation of each monitor, 
including a description of the parameter that is being monitored;

circulation (EGR), secondary air, and air conditioning system. 
Additionally, for diesel engines which also perform misfire, fuel system 
and comprehensive component monitoring under specific driving conditions 
(i.e., non-continuous monitoring; as opposed to spark ignition engines 
that monitor these systems under all conditions or continuous 
monitoring), the manufacturer shall make available monitor-specific 
drive cycles for these monitors. Any manufacturer who develops generic 
drive cycles, either in addition to, or instead of, monitor-specific 
drive cycles shall also make these available in full-text on 
manufacturer Web sites;
    (D) A listing of each monitor sequence, execution frequency and 
typical duration;
    (E) A listing of typical malfunction thresholds for each monitor;
    (F) For OBD parameters for specific engines that deviate from the 
typical parameters, the OBD description shall indicate the deviation and 
provide a separate listing of the typical values for those engines;

[[Page 560]]

    (G) Identification and scaling information necessary to interpret 
and understand data available through Diagnostic Message 8 pursuant to 
SAE J1939-73 (as specified in paragraph (j)(17) of this section), or

perform reinitialization of any computer or anti-theft system following 
an emissions-related repair.
    (7) Anti-theft System Initialization Information. Computer or anti-
theft system initialization information and/or related tools necessary 
for the proper installation of on-board computers or necessary for the 
completion of any emissions-related repair on engines that employ 
integral security systems or the repair or replacement of any other 
emission-related part shall be made available at a fair and reasonable 
cost to the persons specified in paragraph (j)(3)(i) of this section.
    (i) Except as provided under paragraph (j)(7)(ii) of this section, 
manufacturers must make this information available to persons specified 
in paragraph (j)(3)(i) of this section, such that such persons will not 
need any special tools or manufacturer-specific scan tools to perform 
the initialization. Manufacturers may make such information available 
through, for example, generic aftermarket tools, a pass-through device, 
or inexpensive manufacturer specific cables.
    (ii) A manufacturer may request Administrator approval for an 
alternative means to re-initialize engines for some or all model years 
through the 2013 model year by July 27, 2009. The Administrator shall 
approve the request only after the following conditions have been met:
    (A) The manufacturer must demonstrate that the availability of such 
information to aftermarket service providers would significantly 
increase the risk of theft.
    (B) The manufacturer must make available a reasonable alternative 
means to install or repair computers, or to otherwise repair or replace 
an emission-related part.
    (C) Any alternative means proposed by a manufacturer cannot require 
aftermarket technicians to use a manufacturer franchised dealership or 
authorized service networks to obtain information or special tools to 
re-initialize the anti-theft system. All information must come directly 
from the manufacturer or a single manufacturer-specified designee.
    (D) Any alternative means proposed by a manufacturer must be 
available to aftermarket technicians at a fair and reasonable price.
    (E) Any alternative must be available to aftermarket technicians 
within twenty-four hours of the initial request.
    (F) Any alternative must not require the purchase of a special tool 
or tools, including manufacturer-specific tools, to complete this 
repair. Alternatives may include lease of such tools, but only for 
appropriately minimal cost.
    (G) In lieu of leasing their manufacturer-specific tool to meet this 
requirement, a manufacturer may also choose to release the necessary 
information to equipment and tool manufacturers for incorporation into 
aftermarket scan tools. Any manufacturer choosing this option must 
release the information to equipment and tool manufacturers within 60 
days of Administrator approval.
    (8) Cost of required information. (i) All information required to be 
made available by this section, shall be made available at a fair and 
reasonable price. In determining whether a price is fair and reasonable, 
consideration may be given to relevant factors, including, but not 
limited to, the following:

[[Page 561]]

    (A) The net cost to the manufacturer franchised dealerships or 
authorized service networks for similar information obtained from 
manufacturers, less any discounts, rebates, or other incentive programs;
    (B) The cost to the manufacturer for preparing and distributing the 
information, excluding any research and development costs incurred in 
designing and implementing, upgrading or altering the onboard computer 
and its software or any other engine part or component. Amortized 
capital costs for the preparation and distribution of the information 
may be included;
    (C) The price charged by other manufacturers for similar 
information;
    (D) The price charged by manufacturers for similar information prior 
to the launch of manufacturer Web sites;
    (E) The ability of the average aftermarket technician or shop to 
afford the information;
    (F) The means by which the information is distributed;
    (G) The extent to which the information is used, which includes the 
number of users, and frequency, duration, and volume of use; and
    (H) Inflation.
    (ii) Manufacturers must submit to EPA a request for approval of 
their pricing structure for their Web sites and amounts to be charged 
for the information required to be made available under paragraphs 
(j)(4) and (j)(6) of this section at least 180 days in advance of the 
launch of the web site. Subsequent to the approval of the manufacturer 
Web site pricing structure, manufacturers shall notify EPA upon the 
increase in price of any one or all of the subscription options of 20 
percent or more above the previously approved price, taking inflation 
into account.
    (A) The manufacturer shall submit a request to EPA that sets forth a 
detailed description of the pricing structure and amounts, and support 
for the position that the pricing structure and amounts are fair and 
reasonable by addressing, at a minimum, each of the factors specified in 
paragraph (j)(8)(i) of this section.
    (B) EPA will act upon on the request within180 days following 
receipt of a complete request or following receipt of any additional 
information requested by EPA.
    (C) EPA may decide not to approve, or to withdraw approval for a

provide an index of the archived information on the manufacturer Web 
site and how it can be obtained by interested parties. Manufacturers 
shall index their available information with a title that adequately 
describes the contents of the document to which it refers. Manufacturers 
may allow for the ordering of information directly from their Web site, 
or from a Web site hyperlinked to the manufacturer Web site. In the 
alternate, manufacturers shall list a phone number and address where 
aftermarket service providers can call or write to obtain the desired 
information. Manufacturers must also provide the price of each item 
listed, as well as the price of items ordered on a subscription basis. 
To the extent that any additional information is added or changed for 
these model years, manufacturers shall update the index as appropriate. 
Manufacturers will be responsible for ensuring that their information 
distributors do so within one regular business day of receiving the 
order. Items that are less than 20 pages (e.g. technical service

    (iv) For model years 2013 and later, manufacturers shall make 
available to aftermarket service providers the necessary manufacturer-
specific software applications and calibrations needed to initiate pass-
through reprogramming. This software shall be able to run on a standard 
personal computer that utilizes standard operating systems as specified 
in either SAE J2534-1 (as specified in paragraph (j)(17) of this 
section) or TMC RP 1210B (as specified in paragraph (j)(17) of this 
section).
    (v) Manufacturers may take any reasonable business precautions 
necessary to protect proprietary business information and are not 
required to provide this information to any party that does not agree to 
these reasonable business precautions. The requirements to make hardware 
available and to release the information to equipment and tool companies 
apply on July 1, 2013, and within 3 months of model introduction for all 
new model years.
    (14) Generic and enhanced information for scan tools. By July 1, 
2013, manufacturers shall make available to equipment and tool companies 
all generic and enhanced service information including bi-directional 
control and data stream information as defined in paragraph (j)(3(ii) of

layers. (i.e., processing algorithms or software design descriptions for 
procedures such as connection, initialization, and termination),
    (D) Engine application information or any other related service 
information such as special pins and voltages or additional connectors 
that require enablement and specifications for the enablement.
    (iii) Any manufacturer who utilizes an automated process in their 
manufacturer-specific scan tool for diagnostic fault trees shall make 
available to equipment and tool companies the data schema, detail 
specifications, including category types/codes and codes, and data 
format/content structure of the diagnostic trouble trees.
    (iv) Manufacturers can satisfy the requirement of paragraph 
(j)(14)(iii) of

[[Page 564]]

this section by making available diagnostic trouble trees on their 
manufacturer Web sites in full-text.
    (v) Manufacturers shall make all required information available to 
the requesting equipment and tool company within 14 days after the 
request to purchase has been made unless the manufacturer requests 
Administrator approval to refuse to disclose such information to the 
requesting company or requests Administrator approval for additional 
time to comply. After receipt of a request and consultation with the 
affected parties, the Administrator shall either grant or refuse the 
petition based on the evidence submitted during the consultation 
process:
    (A) If the evidence demonstrates that the engine manufacturer has a 
reasonably based belief that the requesting equipment and tool company 
could not produce safe and functionally accurate tools that would not 
cause damage to the engine, the petition for non-disclosure will be 
granted. Engine manufacturers are not required to provide data stream 
and bi-directional control information that would permit an equipment 
and tool company's products to modify an EPA-certified engine or 
transmission configuration.
    (B) If the evidence does not demonstrate that the engine 
manufacturer has a reasonably-based belief that the requesting equipment 
and tool company could not produce safe and functionally accurate tools 
that would not cause damage to the engine, the petition for non-
disclosure will be denied and the engine manufacturer, as applicable, 
shall make the requested information available to the requesting 
equipment and tool company within 2 days of the denial.
    (vi) If the manufacturer submits a request for Administrator 
approval for additional time, and satisfactorily demonstrates to the 
Administrator that the engine manufacturer is able to comply but 
requires additional time within which to do so, the Administrator shall 
grant the request and provide additional time to fully and expeditiously 
comply.
    (vii) Manufacturers may require that tools using information covered 
under paragraph (j)(14) of this section comply with the Component 
Identifier message specified in SAE J1939-71 (as specified in paragraph 
(j)(17) of this section) as Parameter Group Number (PGN) 65249 
(including the message parameter's make, model, and serial number) and 
the SAE J1939-81 (as specified in paragraph (j)(17) of this section) 
Address Claim PGN.
    (viii) Manufacturers are not required to make available to equipment 
and tool companies any information related to reconfiguration 
capabilities or any other information that would make permanent changes 
to existing engine configurations.
    (15) Availability of manufacturer-specific scan tools. (i) By July 
1, 2013, manufacturers shall make available for sale to the persons 
specified in paragraph (j)(3)(i) of this section their own manufacturer-
specific diagnostic tools at a fair and reasonable cost. These tools 
shall also be made available in a timely fashion either through the 
manufacturer Web site or through a manufacturer-designated intermediary. 
Upon Administrator approval, manufacturers will not be required to make 
available manufacturer-specific tools with reconfiguration capabilities 
if they can demonstrate to the satisfaction of the Administrator that 
these tools are not essential to the completion of an emissions-related 
repair, such as recalibration. As a condition of purchase, manufacturers 
may request that the purchaser take all necessary training offered by 
the engine manufacturer. Any required training materials and classes 
must comply with the following:
    (A) Similar training must be required by the engine manufacturer for 
the use of the same tool by its franchised dealerships or authorized 
service networks;
    (B) The training must be substantially similar to such training in 
terms of material covered and the length of training;
    (C) The training must be made available within six months after a 
tool request has been made;
    (D) The training must be made available at a fair and reasonable 
price.
    (ii) Manufacturers shall ship purchased tools in a timely manner 
after a request and training, if any, has been

[[Page 565]]

completed. Any required training materials and classes must be made 
available at a fair and reasonable price. Manufacturers who develop 
different versions of one or more of their diagnostic tools that are 
used in whole or in part for emission-related diagnosis and repair shall 
also insure that all emission-related diagnosis and repair information 
is available for sale to the aftermarket at a fair and reasonable cost. 
Factors for determining fair and reasonable cost include, but are not 
limited to:
    (A) The net cost to the manufacturer's franchised dealerships or 
authorized service network for similar tools obtained from 
manufacturers, less any discounts, rebates, or other incentive programs;
    (B) The cost to the manufacturer for preparing and distributing the 
tools, excluding any research and development costs;
    (C) The price charged by other manufacturers of similar sizes for 
similar tools;
    (D) The capabilities and functionality of the manufacturer tool;
    (E) The means by which the tools are distributed;
    (F) Inflation;
    (G) The ability of aftermarket technicians and shops to afford the 
tools.
    Manufacturers shall provide technical support to aftermarket service 
providers for the tools described in this section, either themselves or 
through a third-party of their choice.
    (16) Changing content of manufacturer-specific scan tools. 
Manufacturers who opt to remove non-emissions related content from their 
manufacturer-specific scan tools and sell them to the persons specified 
in paragraph (j)(3)(i) of this section shall adjust the cost of the tool 
accordingly lower to reflect the decreased value of the scan tool. All 
emissions-related content that remains in the manufacturer-specific tool 
shall be identical to the information that is contained in the complete 
version of the manufacturer-specific tool. Any manufacturer who wishes 
to implement this option must request approval from the Administrator 
prior to the introduction of the tool into commerce.
    (17) Reference materials. Manufacturers shall conform with the 
following industry standards. These documents are incorporated by 
reference in Sec.86.1. Anyone may inspect copies at the U.S. EPA or at 
the National Archives and Records Administration (NARA). For information 
on the availability of this material at U.S. EPA, NARA, or the standard 
making bodies directly, refer to Sec.86.1.

Sec.86.012-2  Definitions.

    The definitions of Sec.86.010-2 continue to apply to model year 
2010 and later model year vehicles. The definitions listed in this 
section apply beginning with model year 2012. Urban bus means a 
passenger-carrying vehicle with a load capacity of fifteen or more 
passengers and intended primarily for intracity operation, i.e., within 
the confines of a city or greater metropolitan area. Urban bus operation 
is characterized by short rides and frequent stops. To facilitate this 
type of operation, more than one set of quick-operating entrance and 
exit doors would normally be installed. Since fares are usually paid in 
cash or tokens, rather than purchased in advance in the form of tickets, 
urban buses would normally have equipment installed for collection of 
fares. Urban buses are also typically characterized by the absence of 
equipment and facilities for long distance travel, e.g., rest rooms, 
large luggage compartments, and facilities for stowing carry-on luggage.

[76 FR 57375, Sept. 15, 2011]



Sec.86.016-1  General applicability.

    (a) Applicability. The provisions of this subpart apply for certain 
types of new heavy-duty engines and vehicles as described in this 
paragraph (a). Note that this subpart does not apply for light-duty 
vehicles, light-duty trucks, or medium-duty passenger vehicles (see 
subpart S of this part for requirements that apply for those vehicles). 
In some cases, manufacturers of heavy-duty engines and vehicles can 
choose whether to meet the requirements of this subpart or the 
requirements of subpart S

[[Page 567]]

of this part; those provisions are therefore considered optional, but 
only to the extent that manufacturers comply with the other set of 
requirements. In cases where a provision applies only for a certain 
vehicle group based on its model year, vehicle class, motor fuel, engine 
type, or other distinguishing characteristics, the limited applicability 
is cited in the appropriate section. The provisions of this subpart 
apply for certain heavy-duty engines and vehicles as follows:
    (1) The provisions of this subpart related to exhaust emission 
standards apply for diesel-cycle and Otto-cycle heavy-duty engines 
installed in vehicles above 14,000 pounds GVWR; however, these vehicles 
may instead be certified under subpart S of this part in certain 
circumstances as specified in Sec.86.1801.
    (2) The provisions of this subpart related to exhaust emission 
standards apply for engines that will be installed in incomplete heavy-
duty vehicles at or below 14,000 pounds GVWR; however, these vehicles 
may instead be certified under subpart S of this part as specified in 
Sec.86.1801.
    (3) Diesel-cycle and Otto-cycle complete heavy-duty vehicles at or 
below 14,000 pounds GVWR and the corresponding engines are not subject 
to the provisions of this subpart related to exhaust emission standards, 
except that these provisions are optional for diesel-cycle engines 
installed in such vehicles until those vehicles become subject to the 
Tier 3 standards under Sec.86.1816-18.
    (4) The provisions of this subpart related to evaporative emission 
standards apply for diesel-cycle and Otto-cycle heavy-duty vehicles as 
follows:
    (i) These provisions do not apply for vehicles at or below 14,000 
pounds GVWR.
    (ii) Vehicles above 14,000 pounds GVWR must meet evaporative 
emission standards as specified in 40 CFR 1037.103. This involves 
meeting the standards specified in Sec. Sec.86.008-10(b) and 86.007-
11(b)(3) and (4) until the Tier 3 standards in Sec.86.1813 start to 
apply.
    (iii) Note that diesel-fueled vehicles are not subject to 
evaporative emissions under this part.
    (5) The provisions of this subpart related to onboard diagnostics 
apply for diesel-cycle and Otto-cycle heavy-duty engines and vehicles as 
follows:
    (i) Engines installed in vehicles above 14,000 pounds GVWR must meet 
the onboard diagnostic requirements specified in Sec.86.010-18.
    (ii) Engines installed in vehicles at or below 14,000 pounds GVWR 
must meet the onboard diagnostic requirements specified in Sec.
86.1806.
    (b) Relationship to subpart S of this part. Unless specified 
otherwise, if engines are not subject to provisions of this subpart or 
if manufacturers choose not to meet optional provisions of this subpart 
as described in paragraph (a) of this section, those engines must be 
installed in vehicles meeting the corresponding requirements under 
subpart S of this part. If a vehicle and its installed engine comply 
with a mix of provisions from this subpart and from subpart S of this 
part, the vehicle must be certified under subpart S of this part, and 
the engine does not need to be certified separately.
    (c) Greenhouse gas emission standards. See 40 CFR parts 1036 and 
1037 for greenhouse gas emission standards that apply for heavy-duty 
engines and vehicles.
    (d) Non-petroleum fueled vehicles. The standards and requirements of 
this part apply to model year 2016 and later non-petroleum fueled motor 
vehicles as follows:
    (1) The standards and requirements of this part apply as specified 
for vehicles fueled with methanol, natural gas, and LPG.
    (2) The standards and requirements of subpart S of this part apply 
as specified for light-duty vehicles and light-duty trucks.
    (3) The standards and requirements of this part applicable to 
methanol-fueled heavy-duty vehicles and engines (including flexible fuel 
vehicles and engines) apply to heavy-duty vehicles and engines fueled 
with any oxygenated fuel (including flexible fuel vehicles and engines). 
Most significantly, this means that the hydrocarbon standards apply as 
NMHCE and the vehicles and engines must be tested using the applicable 
oxygenated fuel according to the

[[Page 568]]

test procedures in 40 CFR part 1065 applicable for oxygenated fuels. For 
purposes of this paragraph (d), oxygenated fuel means any fuel 
containing at least 50 volume percent oxygenated compounds. For example, 
a fuel mixture of 85 gallons of ethanol and 15 gallons of gasoline is an 
oxygenated fuel, while a fuel mixture of 15 gallons of ethanol and 85 
gallons of gasoline is not an oxygenated fuel.
    (4) The standards and requirements of subpart S of this part 
applicable to heavy-duty vehicles under 14,000 pounds GVWR apply to all 
heavy-duty vehicles powered solely by electricity, including plug-in 
electric vehicles and solar-powered vehicles. Use good engineering 
judgment to apply these requirements to these vehicles, including 
applying these provisions to vehicles over 14,000 pounds GVWR. Electric 
heavy-duty vehicles may not generate NOX or PM emission 
credits. Heavy-duty vehicles powered solely by electricity are deemed to 
have zero emissions of regulated pollutants.
    (5) The standards and requirements of this part applicable to 
diesel-fueled heavy-duty vehicles and engines apply to all other heavy-
duty vehicles and engines not otherwise addressed in this paragraph (d).
    (6) See 40 CFR parts 1036 and 1037 for requirements related to 
greenhouse gas emissions.
    (7) Manufacturers may voluntarily certify to the standards of 
paragraphs (d)(3) through (5) of this section before model year 2016. 
Note that other provisions in this part require compliance with the 
standards described in paragraphs (d)(1) and (2) of this section for 
model years before 2016.
    (e) Small volume manufacturers. Special certification procedures are 
available for any manufacturer whose projected combined U.S. sales of 
light-duty vehicles, light-duty trucks, heavy-duty vehicles, and heavy-
duty engines in its product line (including all vehicles and engines 
imported under the provisions of 40 CFR 85.1505 and 85.1509) are fewer 
than 10,000 units for the model year in which the manufacturer seeks 
certification. To certify its product line under these optional 
procedures, the small-volume manufacturer must first obtain the 
Administrator's approval. The manufacturer must meet the eligibility 
criteria specified in Sec.86.098-14(b) before the Administrator's 
approval will be granted. The small-volume manufacturer's certification 
procedures are described in Sec.86.098-14.
    (f) Optional procedures for determining exhaust opacity. (1) The 
provisions of subpart I of this part apply to tests which are performed 
by the Administrator, and optionally, by the manufacturer.
    (2) Measurement procedures, other than those described in subpart I 
of this part, may be used by the manufacturer provided the manufacturer 
satisfies the requirements of Sec.86.007-23(f).
    (3) When a manufacturer chooses to use an alternative measurement 
procedure, it has the responsibility to determine whether the results 
obtained by the procedure will correlate with the results which would be 
obtained from the measurement procedure in subpart I of this part. 
Consequently, the Administrator will not routinely approve or disapprove 
any alternative opacity measurement procedure or any associated 
correlation data which the manufacturer elects to use to satisfy the 
data requirements for subpart I of this part.
    (4) If a confirmatory test is performed and the results indicate 
there is a systematic problem suggesting that the data generated under 
an optional alternative measurement procedure do not adequately 
correlate with data obtained in accordance with the procedures described 
in subpart I of this part, EPA may require that all certificates of 
conformity not already issued be based on data obtained from procedures 
described in subpart I of this part.
    (g) Clean alternative fuel conversions. The provisions of this 
subpart also apply for clean alternative fuel conversions as defined in 
40 CFR 85.502 of all vehicles described in paragraph (a) of this 
section.
    (h) Turbine engines. Turbine engines are deemed to be compression-
ignition engines for purposes of this part.

Sec.86.079-32  Addition of a vehicle or engine after certification.

    (a) If a manufacturer proposes to add to his product line a vehicle 
(or engine) of the same engine-system combination as vehicles (or 
engines) previously certified but which was not described in the 
application for certification when the test vehicle(s) (or test 
engine(s)) representing other vehicles (or engines) of that combination 
was certified, he shall notify the Administrator. Such notification 
shall be in advance of the addition unless the manufacturer elects to 
follow the procedure described in Sec.86.079-34. This notification 
shall include a full description of the vehicle (or engine) to be added.
    (b) The Administrator may require the manufacturer to perform such 
tests on the test vehicle(s) (or test engine(s)) representing the 
vehicle (or engine) to be added which would have been required if the 
vehicle (or engine) had been included in the original application for 
certification.
    (c) If, after a review of the test reports and data submitted by the 
manufacturer, and data derived from any testing conducted under Sec.
86.079-29, the Administrator determines that the test vehicle(s) or test 
engine(s) meets all applicable standards, the appropriate certificate 
will be amended accordingly. If the Administrator determines that the 
test vehicle(s) (or test engine(s)) does not meet applicable standards, 
he will proceed under Sec.86.079-30(b).

parameters listed in Sec.86.079-24(a)(3), Sec.86.079-24(b)(1)(iii), 
Sec.86.079-24(b)(2) (iii) or Sec.86.079-24(b)(3)(iii) as applicable, 
giving a full description of the change. Such notification shall be in 
advance of the change unless the manufacturer elects to follow the 
procedure described in Sec.86.079-34.
    (b) Based upon the description of the change, and data derived from 
such testing as the Administrator may require or conduct. The 
Administrator will determine whether the vehicle (or engine), as 
modified, would still be covered by the certificate of conformity then 
in effect.
    (c) If the Administrator determines that the outstanding certificate 
would cover the modified vehicles (or engines) he will notify the 
manufacturer in writing. Except as provided in Sec.86.079-34 the 
change may not be put into effect prior to the manufacturer's receiving 
this notification. If the Administrator determines that the modified 
vehicles (or engines) would not be covered by the certificate then in 
effect, the modified vehicles (or engines) shall be treated as additions 
to the product line subject to Sec.86.079-32.

[42 FR 45149, Sept. 8, 1977]



Sec.86.079-39  Submission of maintenance instructions.

    (a) The manufacturer shall provide to the Administrator, no later 
than the time of the submission required by Sec.86.079-23, a copy of 
the maintenance instructions which the manufacturer proposes to supply 
to the ultimate purchaser in accordance with Sec.86.079-38(a). The 
Administrator will review such instructions to determine whether they 
are reasonable and necessary to assure the proper functioning of the 
vehicle's (or engine's) emission control systems. The Administrator will 
notify the manufacturer of his determination whether such instructions 
are reasonable and necessary to assure the proper functioning of the 
emission control systems.
    (b) Any revision to the maintenance instructions which will affect 
emissions shall be supplied to the Administrator at least 30 days before 
being supplied to the ultimate purchaser unless the Administrator 
consents to a lesser period of time.

[42 FR 45151, Sept. 8, 1977]



Sec.86.080-12  Alternative certification procedures.

    (a)(1) The Administrator will determine which of the following 
certification procedures (paragraph (a)(3) or (a)(4) of this section) 
may be used to demonstrate compliance for each heavy-duty engine, light-
duty vehicle,

Sec.86.082-34  Alternative procedure for notification of additions 
and changes.

    (a) A manufacturer may, in lieu of notifying the Administrator in 
advance of an addition of a vehicle (or engine) under Sec.86.079-32 or 
a change in a vehicle (or engine) under Sec.86.079-33, notify the 
Administrator concurrently with making an addition of a vehicle or a 
change in a vehicle, if the manufacturer determines that following the 
change all vehicles (or engines) effected by the addition or change will 
still meet the applicable emission standards. Such notification shall 
include a full description of the addition or change and any supporting 
documentation the manufacturer may desire to include to support the 
manufacturer's determination. The manufacturer's determination that the 
addition or change does not cause noncompliance shall be based on an 
engineering evaluation of the addition or change and/or testing.
    (b) The Administrator may require that additional emission testing 
be performed to support the manufacturers original determination 
submitted in

[[Page 576]]

paragraph (a) of this section. If additional testing is required the 
Administrator shall proceed as in Sec.86.079-32 (b) and (c) or Sec.
86.079-33 (b) and (c) as appropriate. Additional test data, if 
requested, must be provided within 30 days of the request or the 
manufacturer must rescind the addition or change immediately. The 
Administrator may grant additional time to complete testing. If based on 
this additional testing or any other information, the Administrator 
determines that the vehicles effected by the addition or change do not 
meet the applicable standards the Administrator will notify the 
manufacturer to rescind the addition or change immediately upon receipt 
of the notification.
    (c) Election to produce vehicles (or engines) under this section 
will be deemed to be a consent to recall all vehicles (or engines) which 
the Administrator determines under Sec.86.079-32(c) do not meet 
applicable standards, and to cause such nonconformity to be remedied at 
no expense to the owner.

Sec.86.084-4  Section numbering; construction.

    (a) The model year of initial applicability is indicated by the last 
two digits of the 5-digit group. A section remains in effect for 
subsequent model years until it is superseded. The number following the 
hyphen designates what previous section is replaced by a future 
regulation. For example, Sec.86.005-1 applies to model year 2005 and 
later vehicles and engines until it is superseded. Section 86.016-1 
takes effect with model year 2016 and continues to apply until it is 
superseded; Sec.86.005-1 no longer applies starting with model year 
2016, except as specified by Sec.86.016-1.
    (b) If a regulation in this subpart references a section that has 
been superseded or no longer exists, this should be understood as a 
reference to the same section for the appropriate model year. For 
example, if a regulation in this subpart refers to Sec.86.001-30, it 
should be taken as a reference to Sec.86.007-30 or any later version 
of that section that applies for the appropriate model year. However, 
this does not apply if the reference to a superseded section 
specifically states that the older provision applies instead of any 
updated provisions from the section in effect for the current model 
year; this occurs most often as part of the transition to new emission 
standards.
    (c) Except where indicated, the language in this subpart applies to 
both vehicles and engines. In many instances, language referring to 
engines is enclosed in parentheses and immediately follows the language 
discussing vehicles.

emission level to which an engine family is certified in the particulate 
averaging program, expressed to an accuracy of one hundredth gram-per-
mile.
    Production-weighted average means the manufacturer's production-
weighted average particulate emission level, for certification purposes, 
of all of its diesel engine families included in the particulate 
averaging program. It is calculated at the end of the model year by 
multiplying each family particulate emission limit by its respective 
production, summing these terms, and dividing the sum by the total 
production of the effected families. Those vehicles produced for sale in 
California or at high altitude shall each be averaged separately from 
those produced for sale in any other area.
    Primary intended service class means:
    (a) The primary service application group for which a heavy-duty 
diesel engine is designed and marketed, as determined by the 
manufacturer. The primary intended service classes are designated as 
light, medium, and heavy heavy-duty diesel engines. The determination is 
based on factors such as vehicle GVW, vehicle usage and operating 
patterns, other vehicle design characteristics, engine horsepower, and 
other engine design and operating characteristics.
    (1) Light heavy-duty diesel engines usually are non-sleeved and not 
designed for rebuild; their rated horsepower generally ranges from 70 to 
170. Vehicle body types in this group might include any heavy-duty 
vehicle built for a light-duty truck chassis, van trucks, multi-stop 
vans, recreational vehicles, and some single axle straight trucks. 
Typical applications would include personal transportation, light-load 
commercial hauling and delivery, passenger service, agriculture, and 
construction. The GVWR of these vehicles is normally less than 19,500 
lbs.
    (2) Medium heavy-duty diesel engines may be sleeved or non-sleeved 
and may be designed for rebuild. Rated horsepower generally ranges from 
170 to 250. Vehicle body types in this group would typically include 
school buses, tandem axle straight trucks, city tractors, and a variety 
of special purpose vehicles such as small dump trucks, and trash 
compactor trucks. Typical applications would include commercial short 
haul and intra-city delivery and pickup. Engines in this group are 
normally used in vehicles whose GVWR varies from 19,500-33,000 lbs.
    (3) Heavy heavy-duty diesel engines are sleeved and designed for 
multiple rebuilds. Their rated horsepower generally exceeds 250. 
Vehicles in this group are normally tractors, trucks, and buses used in 
inter-city, long-haul applications. These vehicles normally exceed 
33,000 lbs GVWR.
    Useful life means:
    (a) For light-duty vehicles a period of use of 5 years or 50,000 
miles, whichever first occurs.
    (b) For a light-duty truck engine family, a period of use of 11 
years or 120,000 miles, whichever occurs first.
    (c) For a gasoline-fueled heavy-duty engine family (and in the case 
of evaporative emission regulations, for gasoline-fueled heavy-duty 
vehicles), a period of use of 8 years or 110,000 miles, whichever first 
occurs.
    (d) For a diesel heavy-duty engine family:
    (1) For light heavy-duty diesel engines, a period of use of 8 years 
or 110,000 miles, whichever first occurs.
    (2) For medium heavy-duty diesel engines, a period of use of 8 years 
or 185,000 miles, whichever first occurs.
    (3) For heavy heavy-duty diesel engines, a period of use of 8 years 
or 290,000 miles, whichever first occurs.
    (e) As an option for both light-duty truck and heavy-duty engine 
families, an alternative useful life period assigned by the 
Administrator under the provisions of paragraph (f) of Sec.86.085-21.
    (f) The useful-life period for purposes of the emissions defect 
warranty and emissions performance warranty shall be a period of 5 
years/50,000 miles whichever first occurs, for light-duty trucks, 
gasoline heavy-duty engines, and light heavy-duty diesel engines. For 
all other heavy-duty diesel engines the aforementioned period is 5 
years/100,000 miles, whichever first occurs. However, in no case may 
this period be

[[Page 580]]

less than the manufacturer's basic mechanical warranty period for the 
engine family.

Sec.86.085-20  Incomplete vehicles, classification.

    For purposes of this part:
    (a) A heavy-duty gasoline-fueled vehicle is considered to be a 
complete vehicle if it has the primary load carrying device or container 
attached at the time the vehicle leaves the control of the manufacturer 
of the engine, and is considered to be an incomplete vehicle if it does 
not.
    (b) For all other heavy-duty vehicles, a vehicle that has the 
primary load carrying device or container attached at the time the 
vehicle is introduced into U.S. commerce is considered to be a complete 
vehicle. Vehicles not considered to be complete vehicles are incomplete 
vehicles. For purposes of determining when a vehicle is introduced into 
U.S. commerce, an assembly of motor vehicle parts is deemed to be a 
vehicle if either of the following applies:
    (1) A piece of equipment that is intended for self-propelled use on 
highways becomes a vehicle when it includes at least an engine, a 
transmission, and a frame. (Note: For purposes of this definition, any 
electrical, mechanical, and/or hydraulic devices attached to engines for 
the purpose of powering wheels are considered to be transmissions.)
    (2) A piece of equipment that is intended for self-propelled use on 
highways becomes a vehicle when it includes a passenger compartment 
attached to a frame with axles.

supply to the Administrator, upon request, a reasonable number of 
production vehicles (or engines) selected by the Administrator which are 
representative of the engines, emission control systems, fuel systems, 
and transmission offered and typical of production models available for 
sale under the certificate. These vehicles (or engines) shall be 
supplied for testing at such time and place and for such reasonable 
periods as the Administrator may require. Heavy-duty engines supplied 
under this paragraph may be required to be mounted in chassis and 
appropriately equipped for operation on a chassis dynamometer.
    (b) [Reserved]
    (c) Any heavy-duty engine or gasoline-fueled heavy-duty vehicle 
manufacturer obtaining certification under this part shall notify the 
Administrator, on a yearly basis, of the number of engines or vehicles 
of such engine family-evaporative emission family-engine displacement-
exhaust emission control system-fuel system combination produced for 
sale in the United States during the preceding year.

          9(a)(iii)(B).

    Critical emission-related components are those components which are 
designed primarily for emission control, or whose failure may result in 
a significant increase in emissions accompanied by no significant 
impairment (or perhaps even an improvement) in performance, 
driveability, and/or fuel economy as determined by the Administrator.
    Critical emission-related maintenance means that maintenance to be 
performed on critical emission-related components.
    Emission-related maintenance means that maintenance which does

emission credits, for use in future model year certification programs as 
permitted by regulation.
    Composite particulate standard, for a manufacturer which elects to 
average light-duty vehicles and light-duty trucks together in either the 
petroleum-fueled or methanol-fueled light-duty particulate averaging 
program, means that standards calculated using the following equation 
and rounded to the nearest one-hundredth (0.01) of a gram per mile:

[[Page 582]]

[GRAPHIC] [TIFF OMITTED] TR06OC93.007

Where:

PRODLDV represents the manufacturer's total petroleum-fueled 
          diesel or methanol-fueled diesel light-duty vehicle production 
          for those engine families being included in the appropriate 
          average for a given model year.
STDLDV represents the light-duty vehicle particulate 
          standard.
PRODLDT represents the manufacturer's total petroleum-fueled 
          diesel or methanol-fueled diesel light-duty truck production 
          for those engine families being included in the appropriate 
          average for a given model year.
STDLDT represents the light-duty truck particulate standard.

    Dedicated vehicle (or engine) means any motor vehicle (or motor 
vehicle engine) engineered and designed to be operated using a single 
fuel. Flexible fuel vehicles and multi-fuel vehicles are not dedicated 
vehicles.
    Diesel means type of engine with operating characteristics 
significantly similar to the theoretical Diesel combustion cycle. The 
non-use of a throttle during normal operation is indicative of a diesel 
engine.

fuels, but not on a mixture of fuels.
    Emission credits mean the amount of emission reductions or 
exceedances, by a heavy-duty engine family, below or above the emission 
standard, respectively. Emission credits below the standard are 
considered as ``positive credits,'' while emission credits above the 
standard are considered as ``negative credits.'' In addition, 
``projected credits'' refer to emission credits based on the projected 
U.S. production volume of the engine family. ``Reserved credits'' are 
emission credits generated within a model year waiting to be reported to 
EPA at the end of the model year. ``Actual credits'' refer to emission 
credits based on actual U.S. production volumes as contained in the end-
of-year reports submitted to EPA. Some or all of these credits may be

actions uncover problems or errors.
    Family emission limit (FEL) means an emission level declared by the 
manufacturer which serves in lieu of an emission standard for 
certification purposes in any of the averaging, trading, or banking 
programs. FELs must be expressed to the same number of decimal places as 
the applicable emission standard. The FEL for an engine family using 
NOX or particulate NCPs must equal the value of the current 
NOX or particulate emission standard.
    Flexible fuel vehicle (or engine) means any motor vehicle (or motor 
vehicle engine) engineered and designed to be operated on any mixture of 
two or more different fuels.
    Methanol-fueled means any motor vehicle or motor vehicle engine that

fuel that contains at least 50 percent methanol (CH3OH) by 
volume) as fuel. Flexible fuel vehicles are methanol-fueled vehicles.
    Non-oxygenated hydrocarbon means organic emissions measured by a 
flame ionization detector, excluding methanol.
    Otto-cycle means type of engine with operating characteristics 
significantly similar to the theoretical Otto combustion cycle. The use 
of a throttle during normal operation is indicative of an Otto-cycle 
engine.
    Primary intended service class has the meaning given in 40 CFR 
1036.140.
    Production weighted particulate average means the manufacturer's 
production-weighted average particulate emission level, for 
certification purposes, of all of its diesel engine families included in 
the light-duty particulate averaging program. It is calculated at the 
end of the model year by multiplying each family particulate emission 
limit by its respective production, summing those terms, and dividing 
the sum by the total production of the effected families. Those vehicles

[[Page 583]]

produced for sale in California or at high altitude shall each be 
averaged separately from those produced for sale in any other area.
    Throttle means a device used to control an engine's power output by 
limiting the amount of air entering the combustion chamber.
    Total hydrocarbon equivalent means the sum of the carbon mass 
emissions of non-oxygenated hydrocarbons, methanol, formaldehyde or 
other organic compounds that are separately measured, expressed as 
gasoline-fueled vehicle hydrocarbons. In the case of exhaust emissions, 
the hydrogen-to-carbon ratio of the equivalent hydrocarbon is 1.85:1. In 
the case of diurnal and hot soak emissions, the hydrogen-to-carbon 
ratios of the equivalent hydrocarbons are 2.33:1 and 2.2:1, 
respectively.
    Trading means the exchange of heavy-duty engine NOX or 
particulate emission credits between manufacturers.
    Useful life means:
    (a) For light-duty vehicles a period of use of 5 years or 50,000

    (e) As an option for both light-duty truck and heavy-duty engine 
families, an alternative useful life period assigned by the 
Administrator under the provisions of paragraph (f) of Sec.86.090-21.
    (f) The useful-life period for purposes of the emissions defect 
warranty and emissions performance warranty shall be a period of 5

Sec.86.091-2  Definitions.

    The definitions of Sec.86.090-2 remain effective. The definitions 
listed in this section apply beginning with the 1991 model year.
    Urban bus means a heavy heavy-duty diesel-powered passenger-carrying 
vehicle with a load capacity of fifteen or more passengers and intended 
primarily for intra-city operation, i.e., within the confines of a city 
or greater metropolitan area. Urban bus operation is characterized by 
short rides and frequent stops. To facilitate this type of operation, 
more than one set of quick-operating entrance and exit doors would 
normally be installed. Since fares are usually paid in cash or tokens 
rather than purchased in advance in the form of tickets, urban buses 
would normally have equipment installed for collection of fares. Urban 
buses are also typically characterized by the absence of equipment and 
facilities for long distance travel, e.g., rest rooms, large luggage 
compartments,

[[Page 585]]

and facilities for stowing carry-on luggage. The useful life for urban 
buses is the same as the useful life for other heavy heavy-duty diesel 
engines.

    (2) [Reserved]
    (3) In order to allow the Administrator to determine whether or not 
production motor vehicles (or production motor vehicle engines) conform 
to the conditions upon which a certificate of conformity has been 
issued, or conform in all material respects to the design specifications 
which applied to those vehicles (or engines) described in the 
application for certification for which a certificate of conformity has 
been issued to standards prescribed under section 202 of the Act, any 
manufacturer shall admit any EPA Enforcement Officer or any EPA 
authorized representative on presentation of credentials to both:
    (i) Any facility where any document, design, or procedure relating 
to the translation of the design and construction of engines and 
emission related components described in the application for 
certification or used for certification testing into production vehicles 
(or production engines) is located or carried on;
    (ii) Any facility where any motor vehicles (or motor vehicle 
engines) to be introduced into commerce are manufactured or assembled; 
and
    (iii) Any facility where records specified in paragraph (c) of this 
section are located.
    (4) On admission to any such facility referred to in paragraph 
(d)(4) of this section, any EPA Enforcement Officer or any EPA 
authorized representative shall be allowed:
    (i) To inspect and monitor any aspects of such manufacture or 
assembly and other procedures;
    (ii) To inspect and make copies of any such records, documents or 
designs;
    (iii) To inspect and photograph any part or aspect of any such new 
motor vehicles (or new motor vehicle engines) and any component used in 
the assembly thereof that are reasonably related to the purpose of his 
entry; and
    (iv) To inspect and make copies of any records and documents 
specified in paragraph (c) of this section.
    (5) Any EPA Enforcement Officer or EPA authorized representative 
shall be furnished by those in charge of a facility being inspected with 
such reasonable assistance as he may request to help him discharge any 
function listed in this paragraph. Each applicant for or recipient of 
certification is required to cause those in charge of a facility 
operated for its benefit to furnish such reasonable assistance without 
charge to EPA whether or not the applicant controls the facility.
    (6) The duty to admit or cause to be admitted any EPA Enforcement 
Officer or EPA authorized representative applies whether or not the 
applicant owns or controls the facility in question and applies both to 
domestic and to foreign manufacturers and facilities. EPA will not 
attempt to make any inspections which it has been informed that local 
law forbids. However, if local law makes it impossible to do what is 
necessary to insure the accuracy of data generated at a facility, no 
informed judgment that a vehicle or engine is certifiable or is covered 
by a certificate can properly be based on those data. It is the 
responsibility of the manufacturer to locate its testing and 
manufacturing facilities in jurisdictions where this situation will not 
arise.
    (7) For purposes of this paragraph:
    (i) Presentation of credentials shall mean display of the document 
designating a person as an EPA Enforcement Officer or EPA authorized 
representative.
    (ii) Where vehicle, component, or engine storage areas or facilities 
are concerned, operating hours shall mean all times during which 
personnel other than custodial personnel are at work in the vicinity of 
the area or facility and have access to it.
    (iii) Where facilities or areas other than those covered by 
paragraph (d)(7)(ii) of this section are concerned, operating hours 
shall mean all times

[[Page 588]]

during which an assembly line is in operation or all times during which 
testing, maintenance, mileage (or service) accumulation, production or 
compilation of records, or any other procedure or activity related to 
certification testing, to translation of designs from the test stage to 
the production stage, or to vehicle (or engine) manufacture or assembly 
is being carried out in a facility.
    (iv) Reasonable assistance includes, but is not limited to, 
clerical, copying, interpretation and translation services, the making 
available on request of personnel of the facility being inspected during 
their working hours to inform the EPA Enforcement Officer or EPA 
authorized representative of how the facility operates and to answer his 
questions, and the performance on request of emissions tests on any 
vehicle (or engine) which is being, has been, or will be used for 
certification testing. Such tests shall be nondestructive, but may 
require appropriate mileage (or service) accumulation. A manufacturer 
may be compelled to cause the personal appearance of any employee at 
such a facility before an EPA Enforcement Officer or EPA authorized 
representative by written request for his appearance, signed by the 
Assistant Administrator for Air and Radiation, served on the 
manufacturer. Any such employee who has been instructed by the 
manufacturer to appear will be entitled to be accompanied, represented, 
and advised by counsel.
    (v) Any entry without 24 hour prior written or oral notification to 
the affected manufacturer shall be authorized in writing by the 
Assistant Administrator for Air and Radiation.
    (8) EPA may void ab initio a certificate of conformity for vehicle 
or engine families introduced into commerce if the manufacturer (or 
contractor for the manufacturer, if applicable) fails to comply with any 
provision of this section.
    (e) EPA Enforcement Officers or EPA authorized representatives are 
authorized to seek a warrant or court order authorizing the EPA 
Enforcement Officers or EPA authorized representatives to conduct 
activities related to entry and access as authorized in this section, as 
appropriate, to execute the functions specified in this section. EPA 
Enforcement Officers or EPA authorized representatives may proceed ex 
parte to obtain a warrant whether or not the Enforcement Officers first 
attempted to seek permission of the manufacturer or the party in charge 
of the facilities in question to conduct activities related to entry and 
access as authorized in this section.
    (f) A manufacturer shall permit EPA Enforcement Officers or EPA 
authorized representatives who present a warrant or court order as 
described in paragraph (e) of this section to conduct activities related 
to entry and access as authorized in this section and as described in 
the warrant or court order. The manufacturer shall cause those in charge 
of its facility or facility operated for its benefit to permit EPA 
Enforcement Officers or EPA authorized representatives to conduct 
activities related to entry and access as authorized in this section 
pursuant to a warrant or court order whether or not the manufacturer 
controls the facility. In the absence of such a warrant or court order, 
EPA Enforcement Officers or EPA authorized representatives may conduct 
activities related to entry and access as authorized in this section 
only upon the consent of the manufacturer or the party in charge of the 
facilities in question.
    (g) It is not a violation of this part or the Clean Air Act for any 
person to refuse to permit EPA Enforcement Officers or EPA authorized 
representatives to conduct activities related to entry and access as 
authorized in this section without a warrant or court order.

Sec.86.091-29  Testing by the Administrator.

    (a) [Reserved]
    (b)(1) Paragraph (b) of this section applies to heavy-duty engines.
    (2) The Administrator may require that any one or more of the test 
engines be submitted to him, at such place or places as he may 
designate, for the purpose of conducting emissions tests. The 
Administrator may specify that he will conduct such testing at the 
manufacturer's facility, in which

[[Page 589]]

case instrumentation and equipment specified by the Administrator shall 
be made available by the manufacturer for test operations. Any testing 
conducted at a manufacturer's facility pursuant to this paragraph shall 
be scheduled by the manufacturer as promptly as possible.
    (3)(i) Whenever the Administrator conducts a test on a test engine 
the results of that test, unless subsequently invalidated by the 
Administrator, shall comprise the official data for the engine at that 
prescribed test point and the manufacturer's data for that prescribed 
test point shall not be used in determining compliance with emission 
standards (or family emission limits, as appropriate).
    (ii) Whenever the Administrator does not conduct a test on a test 
engine at a test point, the manufacturer's test data will be accepted as 
the official data for that test point: Provided, That if the 
Administrator makes a determination based on testing under paragraph 
(b)(2) of this section, that there is a lack of correlation between the 
manufacturer's test equipment and the test equipment used by the 
Administrator, no manufacturer's test data will be accepted for purposes 
of certification until the reasons for the lack of correlation are 
determined and the validity of the data is established by the 
manufacturer, And further provided, That if the Administrator has 
reasonable basis to believe that any test data submitted by the 
manufacturer is not accurate or has been obtained in violation of any 
provision of this part, the Administrator may refuse to accept that data 
as the official data pending retesting or submission of further 
information.
    (iii)(A)(1) The Administrator may adjust or cause to be adjusted any 
adjustable parameter of an emission-data engine which the Administrator 
has determined to be subject to adjustment for certification testing in 
accordance with Sec.86.085-22(e)(1), to any setting within the 
physically adjustable range of that parameter, as determined by the 
Administrator in accordance with Sec.86.085-22(e)(3)(i), prior to the 
performance of any tests to determine whether such engine conforms to 
applicable emission standards, including tests performed by the 
manufacturer under Sec.86.088-23(c)(2). The Administrator, in making 
or specifying such adjustments, may consider the effect of the deviation 
from the manufacturer's recommended setting on emissions performance 
characteristics as well as the likelihood that similar settings will 
occur on in-use heavy-duty engines. In determining likelihood, the 
Administrator may consider factors such as, but not limited to, the 
effect of the adjustment on engine performance characteristics and 
surveillance information from similar in-use engines.
    (2) For those engine parameters which the Administrator has not 
determined to be subject to adjustment for certification testing in 
accordance with Sec.86.085-22(e)(1), the emission-data engine 
presented to the Administrator for testing shall be calibrated within 
the production tolerances applicable to the manufacturer's 
specifications to be shown on the engine label (see Sec.86.091-
35(a)(3)(iii)) as specified in the application for certification. If the 
Administrator determines that an engine is not within such tolerances, 
the engine shall be adjusted at the facility designated by the 
Administrator prior to the test and an engineering report shall be 
submitted to the Administrator describing the corrective action taken. 
Based on the engineering report, the Administrator will determine if the 
engine shall be used as an emission-data engine.
    (B) If the Administrator determines that the test data developed 
under paragraph (b)(3)(iii)(A) of this section would cause the emission-
data engine to fail due to excessive 125-hour emission values or by the 
application of the appropriate deterioration factor, then the following 
procedure shall be observed:
    (1) The manufacturer may request a retest. Before the retest, those 
engine parameters which the Administrator has not determined to be 
subject to adjustment for certification testing in accordance with Sec.
86.085-22(e)(1) may be readjusted to the manufacturer's specifications, 
if these adjustments were made incorrectly prior to the first test. The 
Administrator may adjust or cause to be adjusted any parameter which the 
Administrator has determined to

[[Page 590]]

be subject to adjustment in accordance with Sec.86.085-22(e)(3)(i). 
However, if the idle speed parameter is one which the Administrator has 
determined to be subject to adjustment, the Administrator shall not 
adjust it to a setting which causes a higher engine idle speed than 
would have been possible within the physically adjustable range of the 
idle speed parameter on the engine before it accumulated any dynamometer 
service, all other parameters being identically adjusted for the purpose 
of the comparison. Other maintenance or repairs may be performed in 
accordance with Sec.86.088-25. All work on the vehicle shall be done 
at such location and under such conditions as the Administrator may 
prescribe.
    (2) The engine will be retested by the Administrator and the results 
of this test shall comprise the official data for the emission-data 
engine.
    (iv) If sufficient durability data are not available at the time of 
any emission test conducted under paragraph (b)(2) of this section to 
enable the Administrator to determine whether an emission-data engine 
would fail, the manufacturer may request a retest in accordance with the 
provisions of paragraph (b)(3)(iii)(B) (1) and (2) of this section. If 
the manufacturer does not promptly make such request, he shall be deemed 
to have waived the right to a retest. A request for retest must be made 
before the manufacturer removes the engine from the test premises.
    (c)(1) Paragraph (c) of this section applies to gasoline-fueled and 
methanol-fueled heavy-duty vehicles.
    (2) The Administrator may require that any one or more of the 
evaporative emission family-system combinations included in the 
manufacturer's statement(s) of compliance be installed on an appropriate 
vehicle and such vehicle be submitted to him, at such place or places as 
he may designate, for the purpose of conducting emissions tests. The 
Administrator may specify that he will conduct such testing at the 
manufacturer's facility, in which case instrumentation and equipment 
specified by the Administrator shall be made available by the 
manufacturer for test operations. Any testing conducted at a 
manufacturer's facility pursuant to this paragraph shall be scheduled by 
the manufacturer as promptly as possible.
    (3)(i) Whenever the Administrator conducts a test segment on an 
evaporative emission family-system combination, the results of that test 
segment, unless subsequently invalidated by the Administrator, shall 
comprise the official data for that test segment for the evaporative 
emission family-system combination, and the manufacturer's data, 
analyses, etc., for that test segment shall not be used in determining 
compliance with emission standards. The Administrator may stop a test 
after any evaporative test segment and use as official data any valid 
results obtained up to that point in the test, as described in subpart B 
of this part.
    (ii) Whenever the Administrator does not conduct a test on an 
evaporative emission family-system combination, the manufacturer's test 
data will be accepted as the official data: Provided, That if the 
Administrator makes a determination, based on testing under paragraph 
(c)(2) of this section, that there is a lack of correlation between the 
manufacturer's test equipment and the test equipment used by the 
Administrator, no manufacturer's test data will be accepted for purposes 
of certification until the reasons for the lack of correlation are 
determined and the validity of the data is established by the 
manufacturer, And further provided, That if the Administrator has 
reasonable basis to believe that any test data, analyses, or other 
information submitted by the manufacturer is not accurate or has been 
obtained in violation of any provision of this part, the Administrator 
may refuse to accept those data, analyses, etc., as the official data 
pending retesting or submission of further information.

Sec.86.092-2  Definitions.

    The definitions of Sec.86.091-2 remain effective. The definitions 
listed in this section apply beginning with the 1992 model year.

[[Page 591]]

    (a) Proven emission control systems are emission control components 
or systems (and fuel metering systems) that have completed full 
durability testing evaluation over a vehicle's useful life in some other 
certified engine family, or have completed bench or road testing 
demonstrated to be equal or more severe than certification mileage 
accumulation requirements. Alternatively, proven components or systems 
are those that are determined by EPA to be of comparable functional 
quality and manufactured using comparable materials and production 
techniques as components or systems which have been durability 
demonstrated in some other certified engine family. In addition, the 
components or systems must be employed in an operating environment 
(e.g., temperature, exhaust flow, etc.,) similar to that experienced by 
the original or comparable components or systems in the original 
certified engine family.
    (b) Unproven emission control systems are emission control 
components or systems (and fuel metering systems) that do not qualify as 
proven emission control systems.
    (c) Similar systems are engine, fuel metering and emission control 
system combinations which use the same fuel (e.g., gasoline, diesel, 
etc.), combustion cycle (i.e., two or four stroke), general type of fuel 
system (i.e., carburetor or fuel injection), catalyst system (e.g., 
none, oxidization, three-way plus oxidization, three-way only, etc.), 
fuel control system (i.e., feedback or non-feedback), secondary air 
system (i.e., equipped or not equipped) and EGR (i.e., equipped or not 
equipped).
    (d) Conveniently available service facility and spare parts for 
small-volume manufacturers means that the vehicle manufacturer has a 
qualified service facility at or near the authorized point of sale or 
delivery of its vehicles and maintains an inventory of all emission-
related spare parts or has made arrangements for the part manufacturers 
to supply the parts by expedited shipment (e.g., utilizing overnight 
express delivery service, UPS, etc.).

[55 FR 7187, Feb. 28, 1990]



Sec.86.093-2  Definitions.

    The definitions of Sec.86.092-2 continue to apply. The definitions 
listed in this section apply beginning with the 1993 model year.
    Bus means a heavy heavy-duty diesel-powered passenger-carrying 
vehicle with a load capacity of fifteen or more passengers that is 
centrally fueled, and all urban buses. This definition only applies in 
the context of Sec. Sec.86.093-11 and 86.093-35.
    Centrally fueled bus means a bus that is refueled at least 75 
percent of the time at one refueling facility that is owned, operated, 
or controlled by the bus operator.
    Urban bus means a passenger-carrying vehicle powered by a heavy 
heavy-duty diesel engine, or of a type normally powered by a heavy 
heavy-duty diesel engine, with a load capacity of fifteen or more 
passengers and intended primarily for intracity operation, i.e., within 
the confines of a city or greater metropolitan area. Urban bus operation 
is characterized by short rides and frequent stops. To facilitate this 
type of operation, more than one set of quick-operating entrance and 
exit doors would normally be installed. Since fares are usually paid in 
cash or tokens, rather than purchased in advance in the form of tickets, 
urban buses would normally have equipment installed for collection of 
fares. Urban buses are also typically characterized by the absence of 
equipment and facilities for long distance travel, e.g., rest rooms, 
large luggage compartments, and facilities for stowing carry-on luggage. 
The useful life for urban buses is the same as the useful life for other 
heavy heavy-duty diesel engines.

emission test procedure;
    (2) The need for the AECD is justified in terms of protecting the 
vehicle against damage or accident; or
    (3) The AECD does not go beyond the requirements of engine starting.
    Durability useful life means the highest useful life mileage out of 
the set of all useful life mileages that apply to a given vehicle. The 
durability useful life determines the duration of service accumulation 
on a durability data vehicle. The determination of durability useful 
life shall reflect any alternative useful life mileages approved by the 
Administrator under Sec.86.094-21(f). The determination of durability 
useful life shall exclude any standard and related useful life mileage 
for which the manufacturer has obtained a waiver of emission data 
submission requirements under Sec.86.094-23(c)
    Element of design means any control system (i.e., computer software,

Sec.86.094-14  Small-volume manufacturer certification procedures.

    (a)(1) The small-volume manufacturer certification procedures 
described in paragraphs (b) and (c) of this section are optional. Small-
volume manufacturers may use these optional procedures to demonstrate 
compliance with the general standards and specific emission requirements 
contained in this subpart.
    (2) To satisfy the durability data requirements of the small-volume 
manufacturer certification procedures, manufacturers of vehicles (or 
engines) as described in paragraph (b) of this section may use assigned 
deterioration factors that the Administrator determines by methods 
described in paragraph (c)(3)(ii) of this section. However, if no 
deterioration factor data (either the manufacturer's or industry-wide 
deterioration factor data) are available from previously completed 
durability data vehicles or engines used for certification, 
manufacturers of vehicles (or engines) as described in paragraph (b) of 
this section or with new technology not previously certified may use 
assigned deterioration factors that the Administrator determines by 
alternative methods, based on good engineering judgment. The factors 
that the Administrator determines by alternative methods will be 
published in an advisory letter or advisory circular.
    (b)(1) The optional small-volume manufacturer certification 
procedures apply to heavy-duty vehicles, and heavy-duty engines produced 
by manufacturers with U.S. sales, including all vehicles and engines 
imported under the provisions of Sec. Sec.85.1505 and 85.1509 of this 
chapter (for the model year in which certification is sought) of fewer 
than 10,000 units (Light-Duty Vehicles, Light-Duty Trucks, Heavy-Duty 
Vehicles and Heavy-Duty Engines combined).
    (2) For the purpose of determining the applicability of paragraph 
(b)(1) of this section, the sales the Administrator shall use shall be 
the aggregate of the projected or actual sales of those vehicles and/or 
engines in any of these groupings:
    (i) Vehicles and/or engines produced by two or more firms, one of 
which is 10 percent or greater part owned by another;
    (ii) Vehicles and/or engines produced by any two or more firms if a 
third party has equity ownership of 10 percent or more in each of the 
firms;
    (iii) Vehicles and/or engines produced by two or more firms having a 
common corporate officer(s) who is (are) responsible for the overall 
direction of the companies;
    (iv) Vehicles and/or engines imported or distributed by all firms 
where the vehicles and/or engines are manufactured by the same entity 
and the importer or distributor is an authorized agent of the entity.
    (3) If the aggregated sales, as determined in paragraph (b)(2) of 
this section are less than 301 units, the manufacturers in the 
aggregated relationship may certify under the provisions in this section 
that apply to manufacturers with sales of less than 301 units.
    (4) If the aggregated sales, as determined in paragraph (b)(2) of 
this section are greater than 300 but fewer than 10,000 units, the 
manufacturers in the aggregated relationship may certify under the 
provisions in this section that apply to manufacturers with sales from 
and including 301 through

[[Page 596]]

9,999 motor vehicles and motor vehicles engines per year.
    (5) If the aggregated sales, as determined in paragraph (b)(2) of 
this section are equal to or greater than 10,000 units, then the 
manufacturers involved in the aggregated relationship will be allowed to 
certify a number of units under the small-volume engine family 
certification procedures (reference Sec.86.001-24(e)) in accordance 
with the following criteria:
    (i) If a manufacturer purchases less than 50 percent of another 
manufacturer, each manufacturer retains its right to certify 9,999 units 
using the small-volume engine family certification procedures.
    (ii) If a manufacturer purchases 50 percent or more of another 
manufacturer, the manufacturer with the over 50 percent interest must 
share, with the manufacturer it purchased, its 9,999 units under the 
small-volume engine family certification procedures.
    (iii) In a joint venture arrangement (50/50 ownership) between two 
manufacturers, each manufacturer retains its eligibility for 9,999 units 
under the small-volume engine family certification procedures, but the 
joint venture must draw its maximum 9,999 units from the units allocated 
to its parent manufacturers.
    (c) All the provisions of this subpart apply to small-volume 
manufacturers, except as described in this paragraph (c). The 
appropriate model year of specific sections shall be determined in 
accordance with Sec.86.084-4.
    (1) Section 86.080-12 is not applicable.
    (2) Small-volume manufacturers shall include in their records all 
the information that EPA requires in Sec.86.007-21. This information 
will be considered part of the manufacturer's application for 
certification. However, the manufacturer is not required to submit the 
information to the Administrator unless the Administrator requests it.
    (3) Small-volume manufacturers may satisfy the requirements of Sec.
86.001-24(b) and (c) as follows:
    (i) Emission data. Small-volume manufacturers may select one 
emission data test vehicle (engine) per engine family by the worst-case 
emissions criteria as follows:
    (A) Heavy-duty Otto-cycle engines. The manufacturer shall select one 
emission data engine first based on the largest displacement within the 
engine family. Then within the largest displacement the manufacturer 
shall select, in the order listed, highest fuel flow at the speed of 
maximum rated torque, the engine with the most advanced spark timing, no 
EGR or lowest EGR flow, and no air pump or lowest actual flow air pump.
    (B) Heavy-duty diesel engines. The manufacturer shall select one 
emission data engine based on the highest fuel feed per stroke, 
primarily at the speed of maximum rated torque and secondarily at rated 
speed.
    (ii) Durability data. Small-volume manufacturers may satisfy the 
durability data requirements with the following procedures:
    (A) Manufacturers with aggregated sales of less than 301 motor 
vehicles and motor vehicle engines per year may use assigned 
deterioration factors that the Administrator determines and prescribes. 
The factors will be the Administrator's estimate, periodically updated 
and published in an advisory letter or advisory circular, of the 70th 
percentile deterioration factors calculated using the industry-wide data 
base of previously completed durability data vehicles or engines used 
for certification. However, the manufacturer may, at its option, 
accumulate miles (hours) on a durability data vehicle (engine) and 
complete emission tests for the purpose of establishing its own 
deterioration factors.
    (B)(1) Manufacturers with aggregated sales from and including 301 
through 9,999 motor vehicles and motor vehicle engines per year 
certifying light-duty vehicle exhaust emissions from vehicles equipped 
with proven emission control systems shall use assigned deterioration 
factors that the manufacturer determines based on its good engineering 
judgment. However, the manufacturer may not use deterioration factors 
less than either the average or 70th percentile of all of that 
manufacturer's deterioration factor data, whichever is less. These 
minimum deterioration factors shall be calculated according to 
procedures in paragraph (c)(3)(ii)(B)(2), of this section. If the

[[Page 597]]

manufacturer does not have at least two data points to calculate these 
manufacturer specific average deterioration factors, then the 
deterioration factors shall be no less than the EPA supplied industry-
wide deterioration factors. However, the manufacturer may, at its 
option, accumulate miles on a durability data vehicle and complete 
emission tests for the purpose of establishing its own deterioration 
factors.
    (2) The manufacturer's minimum deterioration factors shall be 
calculated using the deterioration factors from all engine families, 
within the same vehicle/engine-fuel usage category (e.g., gasoline-
fueled light-duty vehicle, etc.) previously certified to the same 
emission standards. The manufacturer shall use only deterioration 
factors from engine families previously certified by the manufacturer 
and the deterioration factors shall not be included in the calculation 
more than once. The deterioration factors for each pollutant shall be 
calculated separately. The manufacturer may, at its option, limit the 
deterioration factors used in the calculation of the manufacturer's 
minimum deterioration factors to those from all similar systems to the 
system being certified if sufficient data (i.e., from at least two 
certified systems) exists. All data eligible to be grouped as similar 
system data shall be used in calculating similar system deterioration 
factors. Any deterioration factors used in calculating similar system 
deterioration factors shall not be included in calculating the 
manufacturer's minimum deterioration factors used to certify any of the 
manufacturer's remaining vehicle systems.
    (C) Manufacturers with aggregated sales from 301 through 9,999 motor 
vehicles and motor vehicle engines and certifying light-duty vehicle 
exhaust emissions from vehicles equipped with unproven emission control 
systems shall use deterioration factors that the manufacturer determines 
from official certification durability data generated by vehicles from 
engine families representing a minimum of 25 percent of the 
manufacturer's sales equipped with unproven emission control systems. 
The sales projections are to be based on total sales projected for each 
engine/system combination. The durability programs applicable to such 
manufacturers for this purpose shall be the Standard AMA, the Production 
AMA and the Alternative Service Accumulation Durability Programs of 
Sec.86.094-13. The durability data vehicle (engine) mileage 
accumulation and emission tests are to be conducted in accordance with 
Sec.86.094-13. The manufacturer must develop deterioration factors by 
generating durability data in accordance with Sec.86.094-13 on a 
minimum of 25 percent of the manufacturer's projected sales (by engine/
system combination) that is equipped with unproven emission control 
systems. The manufacturer must complete the 25 percent durability 
requirement before the remainder of the manufacturer's sales equipped 
with unproven emission control systems is certified using manufacturer-
determined assigned deterioration factors. Alternatively, any of these 
manufacturers may, at their option, accumulate miles on durability data 
vehicles and complete emission tests for the purpose of establishing 
their own deterioration factors on the remaining sales.
    (4) Section 86.001-24(d) and (e) are not applicable.
    (5) Small-volume manufacturers shall comply with the following 
provisions instead of Sec.86.007-30(a)(2) and (b):
    (i) Small-volume manufacturers shall submit an application for 
certification containing the following elements:
    (A) The names, addresses, and telephone numbers of the persons the 
manufacturer authorizes to communicate with us.
    (B) A brief description of the vehicles (or engines) covered by the

Sec.86.094-21  Application for certification.

    (a) A separate application for a certificate of conformity shall be 
made for each set of standards (or family emission limits, as 
appropriate) and each class of new motor vehicles or new motor vehicle 
engines. Such application shall be made to the Administrator by the 
manufacturer and shall be updated and corrected by amendment.
    (b) The application shall be in writing, signed by an authorized 
representative of the manufacturer, and shall include the following:
    (1)(i) Identification and description of the vehicles (or engines) 
covered by the application and a description of their engine (vehicles 
only), emission control system, and fuel system components. This 
description will include:
    (A) A detailed description of each Auxiliary Emission Control Device 
(AECD) to be installed in or on any vehicle (or engine) covered by the 
application;
    (B) A detailed justification of each AECD (described in (b)(1)(i)(A) 
of this section) which results in a reduction in effectiveness of the 
emission control system. Such a justification may be disapproved by 
consideration of currently available technology, whereupon the 
application for certification may be disapproved under Sec.86.094-
22(b) for the incorporation of a defeat device;
    (ii)(A) The manufacturer shall provide to the Administrator in the 
application for certification:
    (1) A list of those parameters which are physically capable of being 
adjusted (including those adjustable parameters for which access is 
difficult) and that, if adjusted to settings other than the 
manufacturer's recommended setting, may affect emissions;
    (2) A specification of the manufacturer's intended physically 
adjustable range of each such parameter, and the production tolerances 
of the limits or

[[Page 600]]

stops used to establish the physically adjustable range;
    (3) A description of the limits or stops used to establish the 
manufacturer's intended physically adjustable range of each adjustable 
parameter, or any other means used to inhibit adjustment;
    (4) The nominal or recommended setting, and the associated 
production tolerances, for each such parameter.
    (B) The manufacturer may provide, in the application for 
certification, information relating to why certain parameters are not 
expected to be adjusted in actual use and to why the physical limits or 
stops used to establish the physically adjustable range of each 
parameter, or any other means used to inhibit adjustment, are effective 
in preventing adjustment of parameters on in-use vehicles to settings 
outside the manufacturer's intended physically adjustable ranges. This 
may include results of any tests to determine the difficulty of gaining 
access to an adjustment or exceeding a limit as intended or recommended 
by the manufacturer.
    (C) The Administrator may require to be provided detailed drawings 
and descriptions of the various emission related components, and/or 
hardware samples of such components, for the purpose of making his 
determination of which vehicle or engine parameter will be subject to 
adjustment for new certification and Selective Enforcement Audit testing 
and of the physically adjustable range for each such vehicle or engine 
parameter.
    (2) Projected U.S. sales data sufficient to enable the Administrator 
to select a test fleet representative of the vehicles (or engines) for 
which certification is requested, and, for model year 1994 through 1995 
light-duty vehicles and light light-duty trucks and model year 1996 
heavy light-duty trucks, data sufficient to determine projected 
compliance with the Tier 1 standards implementation schedules of 
Sec. Sec.86.094-8 and 86.094-9. The data shall also include the 
altitude of intended sale for model year 1994 light-duty trucks 
certified to the Tier 0 standards of Sec.86.094-9. Volume projected to 
be produced for U.S. sale may be used in lieu of projected U.S. sales.
    (3) A description of the test equipment and fuel proposed to be 
used.
    (4)(i) [Reserved]
    (ii) For heavy-duty vehicles equipped with gasoline-fueled or 
methanol-fueled engines, the Administrator does not assume that each 
evaporative emission family-evaporative emission control system 
combination will deteriorate in a unique manner during the useful life 
of the vehicle. The manufacturer shall therefore identify those 
evaporative emission deterioration factors which shall be applied to the 
various evaporative emission family-evaporative emission control system 
combinations which are expected to exhibit similar deterioration 
characteristics during the useful life of the vehicle.
    (5)(i)(A) A description of the test procedures to be used to 
establish the durability data or the exhaust emission deterioration 
factors required to be determined and supplied in Sec.86.094-23(b)(1).
    (B) For each light-duty truck engine family provided an optional 
useful life period under the provisions of paragraph (f) of this 
section, and for each heavy-duty engine family, a statement of the 
useful life.
    (C) For engine families provided an alternative useful-life period 
under paragraph (f) of this section, a statement of that alternative 
period and a brief synopsis of the justification.
    (ii) For heavy-duty diesel engine families, a statement of the 
primary intended service class (light, medium, or heavy) and an 
explanation as to why that service class was selected. Each diesel 
engine family shall be certified under one primary intended service 
class only. After reviewing the guidance in Sec.86.090-2, the class 
shall be determined on the basis of which class best represents the 
majority of the sales of that engine family.
    (iii)(A) For each light-duty vehicle engine family, each light-duty 
truck

[[Page 601]]

engine family, and each heavy-duty engine family, a statement of 
recommended maintenance and procedures necessary to assure that the 
vehicles (or engines) covered by a certificate of conformity in 
operation conform to the regulations, and a description of the program 
for training of personnel for such maintenance, and the equipment 
required.
    (B) [Reserved]
    (iv) At the option of the manufacturer, the proposed composition of 
the emission data test fleet or (where applicable) the durability data 
test fleet.
    (6) [Reserved]
    (7)(i) For Otto-cycle heavy-duty engines, the application must state 
whether the engine family is being certified for use in all vehicles 
regardless of their Gross Vehicle Weight Rating (see Sec.86.091-10 
(a)(1)(i) and (a)(3)(i)), or only for use in vehicles with a Gross 
Vehicle Weight Rating greater than 14,000 pounds.
    (ii) If the engine family is being certified for use in all vehicles 
and is being certified to the emission standards applicable to Otto-
cycle engines for use only in vehicles with a Gross Vehicle Weight 
Rating over 14,000 pounds under the provisions of Sec.86.091-10(a)(3), 
then the application must also attest that the engine family, together 
with all other engine families being certified under the provisions of 
Sec.86.091-10(a)(3), represent no more than 5 percent of model year 
sales of the manufacturer of all Otto-cycle heavy-duty engines for use 
in vehicles with Gross Vehicle Weight Ratings of up to 14,000 pounds.
    (8) [Reserved]
    (c) Complete copies of the application and of any amendments 
thereto, and all notifications under Sec. Sec.86.079-32, 86.079-33, 
and 86.082-34 shall be submitted in such multiple copies as the 
Administrator may require.
    (d) [Reserved]
    (e) For vehicles equipped with gasoline-fueled or methanol-fueled 
heavy-duty engines, the manufacturer shall specify a maximum nominal 
fuel tank capacity for each evaporative emission family-evaporative 
emission control system combination.
    (f) Light-duty truck and heavy-duty engine manufacturers who believe 
that the useful life periods of Sec.86.094-2 are significantly 
unrepresentative for one or more engine families (either too long or too 
short), may petition the Administrator to provide an alternative useful-
life period. This petition must include the full rationale behind the 
request together with any supporting data and other evidence. Based on 
this or other information the Administrator may assign an alternative 
useful-life period. Any petition should be submitted in a timely manner, 
to allow adequate time for a thorough evaluation. For model year 1994 
and later light-duty trucks not subject to the Tier 0 standards of Sec.
86.094-9, alternative useful life periods will be granted only for THC, 
THCE, and idle CO requirements.
    (g) [Reserved]

Sec.86.094-22  Approval of application for certification; test fleet 
selections; determinations of parameters subject to adjustment for 
certification and Selective Enforcement Audit, adequacy of limits,
and physically adjustable ranges.
          
          

    (a) After a review of the application for certification and any 
other information which the Administrator may

[[Page 602]]

require, the Administrator may approve the application and select a test 
fleet in accordance with Sec.86.094-24.
    (b) Disapproval of application. (1) The Administrator may disapprove 
in whole or in part an application for certification for reasons 
including incompleteness, inaccuracy, inappropriate proposed mileage (or 
service) accumulation procedures, test equipment, or fuel; or 
incorporation of defeat devices in vehicles (or on engines) described by 
the application.
    (2) The issuance of a certificate of conformity does not exempt the 
covered vehicles from further evaluation or testing for defeat device 
purposes as described in Sec.86.094-16.
    (c) Where any part of an application is rejected, the Administrator 
shall notify the manufacturer in writing and set forth the reasons for 
such rejection. Within 30 days following receipt of such notification, 
the manufacturer may request a hearing on the Administrator's 
determination. The request shall be in writing, signed by an authorized 
representative of the manufacturer and shall include a statement 
specifying the manufacturer's objections to the Administrator's 
determinations, and data in support of such objections. If, after the 
review of the request and supporting data, the Administrator finds that 
the request raises a substantial factual issue, he shall provide the 
manufacturer a hearing in accordance with Sec.86.078-6 with respect to 
such issue.
    (d) Approval of test procedures. (1) [Reserved]
    (2) Light-duty trucks using the Standard Self-Approval durability 
Program and heavy-duty engines only. The Administrator does not approve 
the test procedures for establishing exhaust emission deterioration 
factors for light-duty trucks using the Standard Self-Approval 
Durability Program described in Sec.86.094-13(f) nor for heavy-duty 
engines. The manufacturer shall submit these procedures and 
determinations as required in Sec.86.094-21(b)(5)(i) prior to 
determining the deterioration factors.
    (3) Heavy-duty vehicles equipped with gasoline-fueled or methanol-
fueled engines only. The Administrator does not approve the test 
procedures for establishing the evaporative emission deterioration 
factors. The test procedure will conform to the requirements in Sec.
86.094-23(b)(3).
    (e) Parameter adjustment requirements. When the Administrator 
selects emission data vehicles for the test fleet, he will at the same 
time determine those vehicle or engine parameters which will be subject 
to adjustment for certification, Selective Enforcement Audit and 
Production Compliance Audit testing, the adequacy of the limits, stops, 
seals, or other means used to inhibit adjustment, and the resulting 
physically adjustable ranges for each such parameter and will then 
notify the manufacturer of his determinations.
    (1) Determining parameters subject to adjustment. (i) Except as 
noted in paragraph (e)(1)(iv) of this section, the Administrator may 
determine to be subject to adjustment the idle fuel-air mixture 
parameter on Otto-cycle vehicles (or engines) (carbureted or fuel-
injected); the choke valve action parameter(s) on carbureted, Otto-cycle 
vehicles (or engines); or any parameter on any vehicle (or engine) 
(Otto-cycle or diesel) which is physically capable of being adjusted, 
may significantly affect emissions, and was not present on the 
manufacturer's vehicles (or engines) in the previous model year in the 
same form and function.
    (ii) The Administrator may, in addition, determine to be subject to 
adjustment any other parameters on any vehicle or engine which is 
physically capable of being adjusted and which may significantly affect 
emissions. However, the Administrator may do so only if he has 
previously notified the manufacturer that he might do so and has found, 
at the time he gave this notice, that the intervening period would be 
adequate to permit the development and application of the requisite 
technology, giving appropriate consideration to the cost of compliance 
within such period. In no event will this notification be given later 
than September 1 of the calendar year two years prior to the model year.
    (iii) In determining the parameters subject to adjustment, the 
Administrator will consider the likelihood that, for each of the 
parameters listed in paragraphs (e)(1) (i) and (ii) of this

[[Page 603]]

section, settings other than the manufacturer's recommended setting will 
occur on in-use vehicles (or engines). In determining likelihood, the 
Administrator may consider such factors as, but not limited to, 
information contained in the preliminary application, surveillance 
information from similar in-use vehicles (or engines), the difficulty 
and cost of gaining access to an adjustment, damage to the vehicle (or 
engine) if an attempt is made to gain such access and the need to 
replace parts following such attempt, and the effect of settings other 
than the manufacturer's recommended setting on vehicle (or engine) 
performance characteristics including emission characteristics.
    (iv) Manual chokes of heavy-duty engines only will not be considered 
a parameter subject to adjustment under the parameter adjustment 
requirements.
    (2)(i) The Administrator shall determine a parameter to be 
adequately inaccessible or sealed if:
    (A) In the case of an idle mixture screw, the screw is recessed 
within the carburetor casting and sealed with lead, thermosetting 
plastic, or an inverted elliptical spacer or sheared off after 
adjustment at the factory, and the inaccessibility is such that the 
screw cannot be accessed and/or adjusted with simple tools in one-half 
hour or for $20 (1978 dollars) or less;
    (B) In the case of a choke bimetal spring, the plate covering the 
bimetal spring is riveted or welded in place, or held in place with 
nonreversible screws;
    (C) In the case of a parameter which may be adjusted by elongating 
or bending adjustable members (e.g., the choke vacuum break), the 
elongation of the adjustable member is limited by design or, in the case 
of a bendable member, the member is constructed of a material which when 
bent would return to its original shape after the force is removed 
(plastic or spring steel materials);
    (D) In the case of any parameter, the manufacturer demonstrates that 
adjusting the parameter to settings other than the manufacturer's 
recommended setting takes more than one-half hour or costs more than $20 
(1978 dollars).
    (ii) The Administrator shall determine a physical limit or stop to 
be an adequate restraint on adjustability if:
    (A) In the case of a threaded adjustment, the threads are 
terminated, pinned, or crimped so as to prevent additional travel 
without breakage or need for repairs which take more than one-half hour 
or cost more than $20 (1978 dollars);
    (B) The adjustment is ineffective at the end of the limits of travel 
regardless of additional forces or torques applied to the adjustment;
    (C) The manufacturer demonstrates that travel or rotation limits 
cannot be exceeded with the use of simple and inexpensive tools 
(screwdriver, pliers, open-end or box wrenches, etc.) without incurring 
significant and costly damage to the vehicle (or engine) or control 
system or without taking more than one-half hour or costing more than 
$20 (1978 dollars).
    (iii) If manufacturer service manuals or bulletins describe routine 
procedures for gaining access to a parameter or for removing or 
exceeding a physical limit, stop, seal or other means used to inhibit 
adjustment, or if surveillance data indicate that gaining access, 
removing, or exceeding is likely, paragraphs (e)(2)(i) and (ii) of this 
section shall not apply for that parameter.
    (iv) In determining the adequacy of a physical limit, stop, seal, or 
other means used to inhibit adjustment of a parameter not covered by 
paragraph (e)(2)(i) or (ii) of this section, the Administrator will 
consider the likelihood that it will be circumvented, removed, or 
exceeded on in-use vehicles. In determining likelihood, the 
Administrator may consider such factors as, but not limited to, 
information contained in the preliminary application; surveillance 
information from similar in-use vehicles (or engines); the difficulty 
and cost of circumventing, removing, or exceeding the limit, stop, seal, 
or other means; damage to the vehicle (or engine) if an attempt is made 
to circumvent, remove, or exceed it and the need to replace parts 
following such attempt; and the effect of settings beyond the limit, 
stop, seal, or other means on vehicle (or engine) performance 
characteristics other than emission characteristics.

[[Page 604]]

    (3) The Administrator shall determine two physically adjustable 
ranges for each parameter subject to adjustment:
    (i)(A) In the case of a parameter determined to be adequately 
inaccessible or sealed, the Administrator may include within the 
physically adjustable range applicable to testing under this subpart 
(certification testing) all settings within the production tolerance 
associated with the nominal setting for that parameter, as specified by 
the manufacturer in the preliminary application for certification; or
    (B) In the case of other parameters, the Administrator shall include 
within this range all settings within physical limits or stops 
determined to be adequate restraints on adjustability. The Administrator 
may also include the production tolerances on the location of these 
limits or stops when determining the physically adjustable range.
    (ii)(A) In the case of a parameter determined to be adequately 
inaccessible or sealed, the Administrator shall include within the 
physically adjustable range applicable to testing under subparts G or K 
(Selective Enforcement Audit and Production Compliance Audit) only the 
actual settings to which the parameter is adjusted during production; or
    (B) In the case of other parameters, the Administrator shall include 
within this range all settings within physical limits or stops 
determined to be adequate restraints on adjustability, as they are 
actually located on the test vehicle (or engine).
    (f) Submittal of advance information. (1) If the manufacturer 
submits the information specified in Sec.86.094-21(b)(1)(ii) in 
advance of its full preliminary application for certification, the 
Administrator shall review the information and make the determinations 
required in paragraph (e) of this section within 90 days of the 
manufacturer's submittal.
    (2) The 90-day decision period is exclusive of the elapsed time 
during which EPA may request additional information from manufacturers 
regarding an adjustable parameter and the receipt of the manufacturers' 
response(s).
    (g) Within 30 days following receipt of notification of the 
Administrator's determinations made under paragraph (e) of this section, 
the manufacturer may request a hearing on the Administrator's 
determinations. The request shall be in writing, signed by an authorized 
representative of the manufacturer, and shall include a statement 
specifying the manufacturer's objections to the Administrator's 
determinations, and data in support of such objections. If, after review 
of the request and supporting data, the Administrator finds that the 
request raises a substantial factual issue, he shall provide the 
manufacturer a hearing in accordance with Sec.86.078-6 with respect to 
such issue.

Sec.86.094-25  Maintenance.

    (a) [Reserved]
    (b) This section specifies emission-related scheduled maintenance 
for purposes of obtaining durability data and for inclusion in 
maintenance instructions furnished to purchasers of new motor vehicles 
and new motor vehicles engines under Sec.86.087-38.
    (1) All emission-related scheduled maintenance for purposes of 
obtaining durability data must occur at the same mileage intervals (or 
equivalent intervals if engines, subsystems, or components are used) 
that will be specified in the manufacturer's maintenance instructions 
furnished to the ultimate purchaser of the motor vehicle or engine under 
Sec.86.094-35. This maintenance schedule may be updated as necessary 
throughout the testing of the vehicle/engine, provided that no 
maintenance operation is deleted from the maintenance schedule after the 
operation has been performed on the test vehicle or engine.
    (2) Any emission-related maintenance which is performed on vehicles, 
engines, subsystems, or components must be technologically necessary to 
assure in-use compliance with the emission standards. The manufacturer 
must submit data which demonstrate to the Administrator that all of the

[[Page 605]]

emission-related scheduled maintenance which is to be performed is 
technologically necessary. Scheduled maintenance must be approved by the 
Administrator prior to being performed or being included in the 
maintenance instructions provided to purchasers under Sec.86.010-38.
    (3) For Otto-cycle light-duty vehicles, light-duty trucks and heavy 
duty engines, emission-related maintenance in addition to, or at shorter 
intervals than, that listed in paragraphs (b)(3) (i) through (vii) of 
this section will not be accepted as technologically necessary, except 
as provided in paragraph (b)(7) of this section.
    (i)(A) [Reserved]
    (B) The cleaning or replacement of Otto-cycle heavy duty engine 
spark plugs shall occur at 25,000 miles (or 750 hours) of use and at 
25,000-mile (or 750-hour) intervals thereafter, for engines certified 
for use with unleaded fuel only.
    (ii) [Reserved]
    (4)-(6) [Reserved]
    (7) Changes to scheduled maintenance. (i) For maintenance practices 
that existed prior to the 1980 model year, only the maintenance items 
listed in paragraphs (b) (3) and (4) of this section are currently 
considered by EPA to be emission-related. The Administrator may, 
however, determine additional scheduled maintenance items that existed 
prior to the 1980 model year to be emission-related by announcement in a 
Federal Register Notice. In no event may this notification occur later 
than September 1 of the calendar year two years prior to the affected 
model year.
    (ii) In the case of any new scheduled maintenance, the manufacturer 
must submit a request for approval to the Administrator for any 
maintenance that it wishes to recommend to purchasers and perform during 
durability determination. New scheduled maintenance is that maintenance 
which did not exist prior to the 1980 model year, including that which 
is a direct result of the implementation of new technology not found in 
production prior to the 1980 model year. The manufacturer must also 
include its recommendations as to the category (i.e., emission-related 
or non-emission-related, critical or non-critical) of the subject 
maintenance and, for suggested emission-related maintenance, the maximum 
feasible maintenance interval. Such requests must include detailed 
evidence supporting the need for the maintenance requested, and 
supporting data or other substantiation for the recommended maintenance 
category and for the interval suggested for emission-related 
maintenance. Requests for new scheduled maintenance must be approved 
prior to the introduction of the new maintenance. The Administrator will 
then designate the maintenance as emission-related or non-emission-
related. For maintenance items established as emission-related, the 
Administrator will further designate the maintenance as critical if the 
component which receives the maintenance is a critical component under 
paragraph (b)(6) of this section. For each maintenance item designated 
as emission-related, the Administrator will also establish a 
technologically necessary maintenance interval, based on industry data 
and any other information available to EPA. Designations of emission-
related maintenance items, along with their identification as critical 
or non-critical, and establishment of technologically necessary 
maintenance intervals, will be announced in the Federal Register.
    (iii) Any manufacturer may request a hearing on the Administrator's 
determinations in this paragraph (b)(7). The request shall be in writing 
and shall include a statement specifying the manufacturer's objections 
to the Administrator's determinations, and data in support of such 
objections. If, after review of the request and supporting data, the 
Administrator finds that the request raises a substantial factual issue, 
he shall provide the manufacturer a hearing as described in 40 CFR part 
1068, subpart G.
    (c) Non-emission-related scheduled maintenance which is reasonable 
and technologically necessary (e.g., oil change, oil filter change, fuel 
filter change, air filter change, cooling system maintenance, adjustment 
of idle speed, governor, engine bolt torque, valve lash, injector lash, 
timing, adjustment of air pump drive belt tension, lubrication of the 
exhaust manifold heat control valve, lubrication of

[[Page 606]]

carburetor choke linkage, retorqueing carburetor mounting bolts, etc.) 
may be performed on durability data vehicles at the least frequent 
intervals recommended by the manufacturer to the ultimate purchaser, 
(e.g., not at the intervals recommended for severe service).
    (d) [Reserved]
    (e) Maintenance on emission data vehicles and engines. (1) 
Adjustment of engine idle speed on emission data vehicles may be 
performed once before the low-mileage/low-hour emission test point. Any 
other engine, emission control system, or fuel system adjustment, 
repair, removal, disassembly, cleaning, or replacement on emission data 
vehicles shall be performed only with the advance approval of the 
Administrator.
    (2)-(3) [Reserved]
    (4) Repairs to vehicle components of an emission data vehicle other 
than the engine, emission control system, or fuel system, shall be 
performed only as a result of part failure, vehicle system malfunction, 
or with the advance approval of the Administrator.
    (f) Equipment, instruments, or tools may not be used to identify 
malfunctioning, maladjusted, or defective engine components unless the 
same or equivalent equipment, instruments, or tools will be available to 
dealerships and other service outlets and:
    (1) Are used in conjunction with scheduled maintenance on such 
components; or
    (2) Are used subsequent to the identification of a vehicle or engine 
malfunction, as provided in paragraph (d)(2) of this section for 
durability data vehicles or in paragraph (e)(1) of this section for 
emission data vehicles; or
    (3) Unless specifically authorized by the Administrator.
    (g) [Reserved]
    (h) All test data, maintenance reports, and required engineering 
reports shall be compiled and provided to the Administrator in 
accordance with Sec.86.090-23.

Sec.86.096-24  Test vehicles and engines.

    (a) General. This paragraph applies to the grouping of vehicles or 
engines into families.
    (1) The vehicles or engines covered by an application for 
certification will be divided into groupings of engines which are 
expected to have similar emission characteristics throughout their 
useful life. Each group of engines with similar emission characteristics 
is defined as a separate engine family.
    (2) To be classed in the same engine family, engines must be 
identical in all the respects listed in paragraphs (a)(2) (i) through 
(x) of this section.
    (i) The cylinder bore center-to-center dimensions.
    (ii)-(iii) [Reserved]
    (iv) The cylinder block configuration (air-cooled or water-cooled: 
L-6, 90 deg., V-8, and so forth).
    (v) The location of the intake and exhaust valves (or ports).
    (vi) The method of air aspiration.
    (vii) The combustion cycle.
    (viii) Catalytic converter characteristics.
    (ix) Thermal reactor characteristics.

coolers) for diesel heavy-duty engines.
    (3)(i) Engines identical in all the respects listed in paragraph 
(a)(2) of this section may be further divided into different engine 
families if the Administrator determines that they may be expected to 
have different emission characteristics. This determination will be 
based upon a consideration of the features of each engine listed in 
paragraphs (a)(3)(i) (A) through (G) of this section.

(a)(2) of this section are treated as belonging to a single engine 
family if the Administrator requires it, after determining that the 
engines may be expected to have similar emission deterioration 
characteristics.
    (4) Where engines are of a type which cannot be divided into engine 
families based upon the criteria listed in paragraphs (a)(2) and (3) of 
this section, the Administrator establishes families for those engines 
based upon those features most related to their emission 
characteristics. Engines that are eligible to be included in the same 
engine family based on the criteria in paragraphs (a)(2) and (a)(3)(i) 
of this section may be further divided into different engine families if 
the manufacturer determines that they may be expected to have different 
emission characteristics. This determination will be based upon a 
consideration of the features of each engine listed in paragraphs (a)(4) 
(i) through (iii) of this section.
    (i) The dimension from the center line of the crankshaft to the 
center line of the camshaft.
    (ii) The dimension from the center line of the crankshaft to the top 
of the cylinder block head face.

which are equipped with gasoline-fueled or methanol-fueled heavy-duty 
engines will be divided into groupings of vehicles on the basis of 
physical features which are expected to affect evaporative emissions. 
Each group of vehicles with similar features must be defined as a 
separate evaporative emission family.
    (13) For gasoline-fueled or methanol-fueled heavy-duty vehicles to 
be classified in the same evaporative emission family, vehicles must be

system combinations for those vehicles based on features most related to 
their evaporative emission characteristics.
    (b) Emission data. (1) [Reserved]
    (2) Otto-cycle heavy-duty emission data engines. This paragraph 
applies to Otto-cycle heavy-duty emission data engines.

engine family based upon features indicating that they may have the 
highest emission levels of the engines in the engine family in 
accordance with the criteria described in paragraphs (b)(2)(iii) (A) and 
(B) of this section.
    (A) The Administrator selects one emission data engine first based 
on the largest displacement within the engine family. Then from those 
within the

[[Page 611]]

largest displacement the Administrator selects, in the order listed, the 
engine with the highest fuel flow at the speed of maximum rated torque, 
with the most advanced spark timing, with no EGR or lowest EGR flow, and 
with no air pump or with the lowest actual flow air pump.
    (B) The Administrator selects one additional engine from within each 
engine family. The engine selected is the engine expected to exhibit the 
highest emissions of those engines remaining in the engine family. If 
all engines within the engine family are similar, the Administrator may 
waive the requirements of this paragraph.
    (iv) If the engines selected in accordance with paragraph 
(b)(2)(iii) of this section do not represent each engine displacement-
exhaust emission control system combination, then the Administrator 
selects one engine of each engine displacement-exhaust emission control 
system combination not represented.
    (v) Within an engine family/displacement/control system combination, 
the manufacturer may alter any emission data engine (or other engine 
including current or previous model year emission data engines and 
development engines provided they meet the emission data engines' 
protocol) to represent more than one selection under paragraph 
(b)(2)(iii) of this section.
    (3) Diesel heavy-duty emission data engines. This paragraph applies 
to diesel-cycle heavy-duty emission data engines.
    (i) Engines will be chosen to be run for emission data based upon 
engine family groupings. Within each engine family, the requirements of 
paragraphs (b)(3) (i) through (iv) of this section must be met.
    (ii) Engines of each engine family will be divided into groups based 
upon their exhaust emission control systems. One engine of each engine 
system combination must be run for smoke emission data and gaseous 
emission data. Either the complete gaseous emission test or the complete 
smoke test may be conducted first. Within each combination, the engine 
that features the highest fuel feed per stroke, primarily at the speed 
of maximum rated torque and secondarily at rated speed, will usually be 
selected. If there are military engines with higher fuel rates than 
other engines in the same engine system combinations, then one military 
engine is also selected. The engine with the highest fuel feed per 
stroke is usually the one selected.
    (iii) The Administrator may select a maximum of one additional 
engine within each engine-system combination based upon features 
indicating that it may have the highest emission levels of the engines 
of that combination. In selecting this engine, the Administrator will 
consider such features as the injection system, fuel system, compression 
ratio, rated speed, rated horsepower, peak torque speed, and peak 
torque.
    (iv) Within an engine family control system combination, the 
manufacturer may alter any emission data engine (or other engine 
including current or previous model year emission data engines and 
development engines provided they meet the emission data engines' 
protocol) to represent more than one selection under paragraphs (b)(3) 
(ii) and (iii) of this section.
    (c) Durability data. (1)-(2) [Reserved]
    (3) Heavy-duty engines. This paragraph applies to engines, 
subsystems, or components used to establish exhaust emission 
deterioration factors for heavy-duty engines.
    (i) The manufacturer must select the engines, subsystems, or 
components to be used to determine exhaust emission deterioration 
factors for each engine-family control system combination. Whether 
engines, subsystems, or components are used, they must be selected so 
that their emission deterioration characteristics may be expected to 
represent those of in-use engines, based on good engineering judgment.
    (ii) [Reserved]
    (d) [Reserved]
    (e)(1) [Reserved]
    (2) Any manufacturer may request to certify engine families with 
combined total sales of fewer than 10,000 light-duty vehicles, light-
duty trucks, heavy-duty vehicles, and heavy-duty engines utilizing the 
procedures contained in Sec.86.094-14 for emission data vehicle 
selection and determination of deterioration factors. The deterioration 
factors are applied only to entire engine families.

 Subpart B_Emission Regulations for 1977 and Later Model Year New Light-
  Duty Vehicles and New Light-Duty Trucks and New Otto-Cycle Complete 
                  Heavy-Duty Vehicles; Test Procedures

    Source: 42 FR 32954, June 28, 1977, unless otherwise noted.



Sec.86.101  General applicability.

    (a) General provisions. This subpart describes test procedures for 
measuring exhaust, evaporative, and refueling emissions from motor 
vehicles subject to emission standards under subpart S of this part. 
This generally includes light-duty vehicles, light-duty trucks, and 
complete heavy-duty vehicles at or below 14,000 pounds GVWR. The 
following provisions apply for all testing under this subpart:
    (1) Provisions of this subpart apply to tests performed by both the 
Administrator and manufacturers.
    (2) References in this subpart to engine families and emission 
control systems apply to durability groups and test groups as 
applicable.
    (3) Except as noted, heavy-duty vehicles are subject to all the same 
provisions of this subpart that apply to light-duty trucks.
    (4) The procedures in this subpart apply for testing vehicles 
powered by any fuel, except as specified in subpart S of this part.
    (5) For exhaust emission testing, measure emissions for all 
pollutants with an applicable emission standard.
    (6) All emission control systems designed for production vehicles 
must be functioning during testing. Maintenance to correct component 
malfunction or failure must be authorized in accordance with Sec.
86.1834.
    (7) The test sequence for the Federal Test Procedure (FTP) includes 
steps to precondition vehicles for evaporative emission measurements; 
these steps are required for exhaust testing whether or not testing 
includes evaporative emission measurements.
    (8) Evaporative emission measurement procedures of this subpart 
include specifications for testing methanol-fueled vehicles. For 
vehicles fueled with other oxygenated fuels, use good engineering 
judgment to apply these procedures. For example, if you are testing an 
ethanol-fueled vehicle, perform diagnostics in your evaporative emission 
enclosure with ethanol and propane.
    (9) For exhaust emission testing with ethanol-gasoline blends that 
have less than 25% ethanol by volume, if you use NMHC-to-NMOG conversion 
factors instead of measuring oxygenates as described in 40 CFR 1066.635, 
the testing specifications and diagnostic requirements in this part 86 
that are specific to ethanol-gasoline blends do not apply.
    (b) Migration to 40 CFR parts 1065 and 1066. This subpart 
transitions to rely

[[Page 623]]

on the test procedure specifications in 40 CFR parts 1065 and 1066 as 
follows:
    (1) Through model year 2021, manufacturers may use the test 
procedures specified in paragraph (c) or (d) of this section or, using 
good engineering judgement, elements of both. For any EPA testing before 
model year 2022, EPA will use the manufacturer's selected procedures for 
applying acceptable speed-tolerance criteria (either Sec.86.115-78 or 
40 CFR 1066.425(c)). For any other parameters, EPA may conduct testing 
using either of the specified procedures. As allowed under this part, 
manufacturers may use carryover data from previous model years to 
demonstrate compliance with emission standards, without regard to the 
provisions of this section.
    (2) Manufacturers must use the following procedures before model 
year 2022:
    (i) For vehicles certified to any of the Tier 3 emission standards 
specified in subpart S of this part, determine overall driver accuracy 
based on drive-cycle metrics as described in 40 CFR 1066.425(j).
    (ii) Equipment specifications and measurement procedures that are 
specific to PM emissions from 40 CFR part 1066 apply for any vehicles 
certified to the Tier 3 PM emission standards specified in subpart S of 
this part.
    (iii) Use 40 CFR 1066.635 to determine NMOG for any vehicles 
certified to the Tier 3 NMOG + NOX emission standards in 
subpart S of this part.
    (3) For model years 2022 and later, manufacturers must use the test 
procedures specified in paragraph (d) of this section. Manufacturers may 
continue to use data based on the test procedures specified in paragraph 
(c) of this section for an engine family in 2022 and later model years, 
as long as the engine family is eligible for certification with 
carryover emission data.
    (c) Interim procedures. Test vehicles as described in this subpart 
for the appropriate model year, through model year 2021, as follows:
    (1) Sections 86.106 through 86.115 set forth general testing 
specifications and equipment requirements. Sections 86.116 through 
86.126 discuss calibration methods and frequency. Sections 86.127 
through 86.145 describe procedures for measuring exhaust and evaporative 
emissions. Sections 86.146 through 86.157 lay out refueling test 
procedures. Sections 86.158 through 86.166 cover procedures related to 
the Supplemental Federal Test Procedure and testing related to air 
conditioning systems. The test procedure for measuring fuel system leaks 
is described in 40 CFR 1066.985.
    (2) Alternate equipment, procedures, and calculation methods may be 
used if shown to yield equivalent or superior results, and if approved 
in advance by the Administrator.
    (d) Long-term procedures. Test vehicles as described in 40 CFR parts 
1065 and 1066. The following requirements from this subpart also apply:
    (1) Use fuel for testing and service accumulation as specified in 
Sec.86.113.
    (2) Perform evaporative emission tests as follows:
    (i) Use evaporative testing equipment meeting the specifications in 
Sec.86.107. This equipment must meet calibration requirements as 
specified in Sec.86.117.
    (ii) Generate fuel test temperature profiles as described in Sec.
86.129-94(d).
    (iii) Follow the general provisions and driving schedules described 
in 40 CFR part 1066, subpart I. Evaporative testing consists of vehicle 
preconditioning as described in Sec.86.132, diurnal measurement as 
described in Sec.86.133, running loss testing as described in Sec.
86.134, and hot soak testing as described in Sec.86.138.
    (iv) Calculate emission results as described in Sec.86.143.
    (3) Keep records as described in Sec.86.142
    (4) Perform refueling emission tests, calculate emission results, 
and keep associated records as described in Sec.86.146 through 86.157.

Sec.86.104  Section numbering; construction.

    (a) The model year of initial applicability is indicated by the 
section number. The two digits following the hyphen designate the first 
model year for which a section is effective. A section remains effective 
until superseded.

    Example. Section 86.111-78 applies to the 1978 and subsequent model 
years until superseded. If a Sec.86.111-81 is promulgated it would 
take effect beginning with the 1981 model year; Sec.86.111-78 would 
apply to model years 1978 through 1980.

    (b) A section reference without a model year suffix refers to the 
section applicable for the appropriate model year.
    (c) Unless indicated otherwise, all provisions in this subpart apply 
to petroleum-fueled, natural gas-fueled, liquefied petroleum gas-fueled 
and methanol-fueled vehicles.

Sec.86.105  Introduction; structure of subpart.

    (a) This subpart describes the equipment required and the procedures 
to follow in order to perform gaseous exhaust, particulate, and 
evaporative emission tests on light-duty vehicles and light-duty trucks. 
Subpart A of this part sets forth testing requirements and test 
intervals necessary to comply with EPA certification procedures. Not all 
emission measurement techniques described in this subpart will be 
necessary for all vehicles. Subpart A of this part defines the 
conditions under which vehicles may be exempted from measuring methane 
and/or waived from measuring particulate matter.
    (b) Three topics are addressed in this subpart. Sections 86.106 
through 86.115 set forth specifications and equipment requirements; 
Sec. Sec.86.116 through 86.126 discuss calibration methods and 
frequency; test procedures and data requirements are listed in 
Sec. Sec.86.127 through 86.157.

[56 FR 25760, June 5, 1991, as amended at 59 FR 16295, Apr. 6, 1994; 59 
FR 48504, Sept. 21, 1994]



Sec.86.106-96  Equipment required; overview.

    (a) This subpart contains procedures for exhaust emission tests on 
petroleum-fueled, natural gas-fueled, liquefied petroleum gas-fueled, 
and methanol-fueled light-duty vehicles and light-duty trucks, and for 
evaporative emission tests on gasoline-fueled, natural gas-fueled, 
liquefied petroleum gas-fueled, and methanol-fueled light-duty vehicles 
and light-duty trucks. Certain items of equipment are not necessary for 
a particular test, e.g., evaporative enclosure when testing petroleum-
fueled diesel vehicles. Alternate equipment, procedures, and calculation 
methods may be used if shown to yield equivalent or superior results, 
and if approved in advance by the Administrator. Equipment required and 
specifications are as follows:
    (1) Evaporative emission tests, gasoline-fueled vehicles. The 
evaporative emission test is closely related to and connected with the 
exhaust emission test. All vehicles tested for evaporative emissions 
must undergo testing according to the test sequences described in Sec.
86.130-96; however, the Administrator may omit measurement of exhaust 
emissions to test for evaporative emissions. The Administrator may 
truncate a test after any valid emission measurement without affecting 
the validity of the test. Further, unless the evaporative emission test 
is waived by the Administrator under Sec.86.090-26 or Sec.86.1810, 
as applicable, all vehicles must undergo both tests. (Petroleum-fueled 
diesel vehicles are excluded from the evaporative emission standard.) 
Section 86.107 specifies the necessary equipment.
    (2) Exhaust emission tests. All vehicles subject to this subpart are 
subject to testing for both gaseous and particulate exhaust emissions 
using the CVS concept (see Sec.86.109), except where exemptions or 
waivers are expressly provided in subpart A of this part. Vehicles 
subject to the ``Tier 0'' (i.e., phase-out) standards described under 
subpart A of this part are exempted from testing for methane emissions. 
Otto-cycle vehicles subject to the ``Tier 0'' standards are waived from 
testing for particulates. For vehicles waived from the requirement for 
measuring particulate

[[Page 625]]

emissions, use of a dilution tunnel is not required (see Sec.86.109). 
The CVS must be connected to the dilution tunnel if particulate emission 
sampling is required (see Sec.86.110). Petroleum- and methanol-fueled 
diesel-cycle vehicle testing requires that a PDP-CVS or CFV-CVS with 
heat exchanger be used. (This equipment may be used with methanol-fueled 
Otto-cycle vehicles; however, particulates need not be measured for 
vehicles that are waived from the requirement). All vehicles equipped 
with evaporative canisters are preconditioned by loading the canisters 
with hydrocarbon vapors. Petroleum-fueled diesel vehicles are excluded 
from this requirement.
    (3) Fuel, analytical gas, and driving schedule specifications. Fuel 
specifications for exhaust and evaporative emission testing and for 
mileage accumulation for petroleum-fueled and methanol-fueled vehicles 
are specified in Sec.86.113. Analytical gases are specified in Sec.
86.114. The Urban Dynamometer Driving Schedule (UDDS), US06, and SC03 
driving schedules, for use in exhaust emission tests, and the New York 
City Cycle (NYCC), for use with the UDDS in running loss tests, are 
specified in Sec. Sec.86.115, 86.130, 86.159, 86.160, and appendix I 
to this part.

Sec.86.107-96  Sampling and analytical systems; evaporative emissions.

    (a) Testing enclosures--(1) Diurnal emission test. The enclosure 
shall be readily sealable, rectangular in shape, with space for 
personnel access to all sides of the vehicle. When sealed, the enclosure 
shall be gas tight in accordance with Sec.86.117-96. Interior surfaces 
must be impermeable and nonreactive to hydrocarbons (and to methanol, if 
the enclosure is used for methanol-fueled vehicles). The temperature 
conditioning system shall be capable of controlling the internal 
enclosure air temperature to follow the prescribed temperature versus 
time cycle as specified in Sec.86.133-96 and appendix II of this part, 
within an instantaneous tolerance of 3.0 [deg]F of 
the nominal temperature versus time profile throughout the test, and an 
average tolerance of 2.0 [deg]F over the duration of the test (where the 
average is calculated using the absolute value of each measured 
deviation). The control system shall be tuned to provide a smooth 
temperature pattern that has a minimum of overshoot, hunting, and 
instability about the desired long-term ambient temperature profile. 
Interior surface temperatures shall not be less than 40 [deg]F at any 
time during the diurnal emission test. To accommodate the volume changes 
due to enclosure temperature changes, either a variable-volume or fixed-
volume enclosure may be used for diurnal emission testing:
    (i) Variable-volume enclosure. The variable-volume enclosure expands 
and contracts in response to the temperature change of the air mass in 
the enclosure. Two potential means of accommodating the internal volume 
changes are movable panel(s), or a bellows design, in which impermeable 
bag(s) inside the enclosure expand and contract in response to internal 
pressure changes by exchanging air from outside the enclosure. Any 
design for volume accommodation must maintain the integrity of the 
enclosure as specified in Sec.86.117-96 over the specified temperature 
range. Any method of volume accommodation shall limit the differential 
between the enclosure internal pressure and the barometric pressure to a 
maximum value of 2.0 inches of water. The 
enclosure shall be capable of latching to a fixed volume. A variable-
volume enclosure must be capable of accommodating a 7 percent change from its ``nominal volume'' (see Sec.
86.117-96(b)), accounting for temperature and barometric pressure 
variation during testing.
    (ii) Fixed-volume enclosure. The fixed-volume enclosure shall be 
constructed with rigid panels that maintain a fixed enclosure volume, 
and meet the following requirements.
    (A) The enclosure shall be equipped with a mechanism to maintain a 
fixed internal air volume. This may be accomplished either by 
withdrawing air at a constant rate and providing makeup air as needed, 
or by reversing the flow of air into and out of the enclosure in 
response to rising or falling

[[Page 626]]

temperatures. If inlet air is added continuously throughout the test, it 
should be filtered with activated carbon to provide a relatively low and 
constant hydrocarbon level. Any method of volume accommodation shall 
maintain the differential between the enclosure internal pressure and 
the barometric pressure to a maximum value of 2.0 
inches of water.
    (B) The equipment shall be capable of measuring the mass of 
hydrocarbon and methanol (if the enclosure is used for methanol-fueled 
vehicles) in the inlet and outlet flow streams with a resolution of 0.01 
gram per hour. A bag sampling system may be used to collect a 
proportional sample of the air withdrawn from and admitted to the 
enclosure. Alternatively, the inlet and outlet flow streams may be 
continuously analyzed using an on-line FID analyzer and integrated with 
the flow measurements to provide a continuous record of the mass 
hydrocarbon and methanol removal.
    (2) Running loss test. The enclosure shall be readily sealable, 
rectangular in shape, with space for personnel access to all sides of 
the vehicle. When sealed, the enclosure shall be gas tight in accordance 
with Sec.86.117-96. The enclosure may be equipped with a personnel 
door, provided that the enclosure can still meet the requirements of 
Sec.86.117-96 with the door installed. Interior surfaces must be 
impermeable and nonreactive to hydrocarbons and to methanol (if the 
enclosure is used for methanol-fueled vehicles). Interior surface 
temperatures shall not be less than 40 [deg]F. If a running loss 
enclosure meets all the requirements of paragraph (a)(1) of this 
section, it may be used as a diurnal evaporative emission enclosure. The 
enclosure must contain a dynamometer that meets the requirements of 
Sec.86.108. Provisions shall be made to remove exhaust gases from the 
enclosure. During the running loss test, ambient temperatures must be 
maintained at 955 [deg]F (952 [deg]F on average). An air or oxygen cylinder with an 
attached self-contained breathing apparatus may be provided for the 
vehicle operator. The air required for vehicle operation shall be 
provided by one of the following methods:
    (i) The running loss enclosure may be equipped to supply air to the 
vehicle, at a temperature of 955 [deg]F, from 
sources outside of the running loss enclosure directly into the 
operating engine's air intake system. Supplemental air requirements 
(e.g., for an air pump) shall be supplied by drawing air from the engine 
intake source.
    (ii) If it is shown to yield equivalent or superior results, the 
running loss enclosure may be designed with an air makeup system that 
brings outside air into the enclosure to accommodate the aspiration 
needs of the engine and any auxiliary devices. The makeup air shall be 
monitored to establish the background hydrocarbon levels (or hydrocarbon 
and methanol, levels, if applicable) of the makeup air. A filter may be 
used to provide dry air with a stable concentration of background 
hydrocarbon. The makeup-air vent shall be readily sealable for 
calibration of the enclosure and other purposes. For calculation of 
running loss emissions, it may be assumed that the hydrocarbon and 
methanol concentration in the air consumed by the vehicle is the same as 
that of the rest of the air in the enclosure.
    (3) Hot soak test. The hot soak test may be conducted by holding the 
vehicle in an enclosure that meets the requirements for either diurnal 
emission or running loss tests. The enclosure shall be configured to 
provide an internal enclosure ambient temperature of 9510 [deg]F for the first 5 minutes, and 955 [deg]F (952 [deg]F on average) 
for the remainder of the hot soak test.
    (i) If the hot soak test is conducted in the same enclosure as the 
immediately preceding running loss test, interior surface temperatures 
shall not be below 70 [deg]F for the last 55 minutes of the hot soak 
test.
    (ii) If the hot soak test is not conducted in the same enclosure as 
the immediately preceding running loss test, interior surface 
temperatures shall not be below 70 [deg]F for the duration of the hot 
soak test.
    (b) Evaporative emission hydrocarbon and methanol analyzers. (1) For 
gasoline fueled, natural gas-fueled, liquefied petroleum gas-fueled and 
methanol-fueled vehicles a hydrocarbon analyzer utilizing the hydrogen 
flame ionization

[[Page 627]]

principle (FID) shall be used to monitor the atmosphere within the 
enclosure (a heated FID (HFID)(235[deg]15 [deg]F 
(1138 [deg]C)) is recommended for methanol-fueled 
vehicles). For natural gas-fueled vehicles, the FID may be calibrated 
using methane, or if calibrated using propane the FID response to 
methane shall be determined and applied to the FID hydrocarbon reading. 
Provided evaporative emission results are not effected, a probe may be 
used to detect or verify hydrocarbon sources during a running loss test. 
Instrument bypass flow may be returned to the enclosure. The FID shall 
have a response time to 90 percent of final reading of less than 1.5 
seconds.
    (2) For methanol-fueled vehicles, a methanol sampling and analyzing 
system is required in addition to the FID analyzer. The methanol 
sampling equipment shall consist of impingers for collecting the 
methanol sample and appropriate equipment for drawing the sample through 
the impingers. The analytical equipment shall consist of a gas 
chromatograph equipped with a flame ionization detector.
    (3) The methanol sampling system shall be designed such that, if a 
test vehicle emitted the maximum allowable level of methanol (based on 
all applicable standards) during any phase of the test, the measured 
concentration in the primary impinger would exceed either 25 mg/l or a 
concentration equal to 25 times the limit of detection for the GC 
analyzer, and such that the primary impinger collects at least 90 
percent of the analyte in the samples. The remaining analyte shall be 
collected by the secondary impinger. This requirement does not apply to 
dilution air samples, since they do not require secondary impingers, or 
to samples in which the concentrations approach the limit of detection. 
The provisions of this paragraph apply to the design of sampling 
systems, not to individual tests.
    (c) Evaporative emission hydrocarbon and methanol data recording 
system. (1) The electrical output of the FID used for measuring 
hydrocarbons (or hydrocarbons plus methanol, as appropriate) shall be 
recorded at least at the initiation and termination of each running loss 
and hot soak test, and at least at the initiation and termination of the 
enclosure sampling period(s) for the diurnal emission test, as described 
in Sec.86.133. The recording may be taken by means of a strip chart 
potentiometric recorder, by use of an on-line computer system or other 
suitable means. In any case, the recording system must have operational 
characteristics (signal-to-noise ratio, speed of response, etc.) 
equivalent to or better than those of the signal source being recorded, 
and must provide a permanent record of results. The record shall show a 
positive indication of the initiation and completion of each hot soak, 
running loss, or diurnal emission test (including initiation and 
completion of sampling period(s)), along with the time elapsed during 
each soak.
    (2) For the methanol sample, permanent records shall be made of the 
following: the volumes of deionized water introduced into each impinger, 
the rate and time of sample collection, the volumes of each sample 
introduced into the gas chromatograph, the flow rate of carrier gas 
through the column, the column temperature, and the chromatogram of the 
analyzed sample.
    (d) Fuel temperature control system. Fuel temperatures of the test 
vehicle shall be controlled, as specified in Sec.86.134(g)(1)(xv), 
with the following combination of fans. The control system shall be 
tuned and operated to provide a smooth and continuous fuel temperature 
profile that is representative of the on-road temperature profile. The 
running loss test configuration should be designed to avoid heating or 
cooling the fuel tank's vapor space in a way that would cause vapor 
temperature behavior to be unrepresentative of the vehicle's on-road 
profile.
    (1) A vehicle cooling fan shall discharge air to the front of the 
vehicle. The fan shall be a road-speed modulated fan that is controlled 
to a discharge velocity that follows the dynamometer roll speed, at 
least up to speeds of 30 mph, throughout the driving cycle. If a warning 
light or gauge indicates that the vehicle's engine coolant has 
overheated, subsequent test runs on the vehicle must include a vehicle 
cooling fan that follows the dynamometer roll speed at all speeds 
throughout the test cycle. The fan may

[[Page 628]]

direct airflow to both the vehicle radiator air inlet(s) and the vehicle 
underbody.
    (2) An additional fan may be used to discharge airflow from the 
front of the vehicle directly to the vehicle underbody to control fuel 
temperatures. Such a fan shall provide a total discharge airflow not to 
exceed 8,000 cfm.
    (3) Additional fans may be used to route heating or cooling air 
directly at the bottom of the vehicle's fuel tank. The air supplied to 
the tank shall be between 85[deg] and 160 [deg]F, with a total discharge 
airflow not to exceed 4,000 cfm. For exceptional circumstances, 
manufacturers may direct up to 6,000 cfm at the bottom of the fuel tank 
with the advance approval of the Administrator.
    (4) Direct fuel heating may be needed for canister preconditioning, 
as specified in Sec.86.132(j)(2). Also, under exceptional 
circumstances in which airflow alone is insufficient to control fuel 
temperatures during the running loss test, direct fuel tank heating may 
be used (see Sec.86.134-96(g)(1)(xv)). The heating system must not 
cause hot spots on the tank wetted surface that could cause local 
overheating of the fuel. Heat must not be applied directly to the tank's 
vapor space, nor to the liquid-vapor interface.
    (e) [Reserved]
    (f) Pressure recording system. A strip chart potentiometric 
recorder, an on-line computer system, or other suitable means, shall be 
used to record the enclosure gage pressure for any testing in an 
enclosure, as well as the vehicle's fuel tank pressure during the 
running loss test and the outdoor driving procedure specified in Sec.
86.129-94(d). Fuel tank pressure measurement and recording equipment are 
optional during the running loss test. The recording system shall record 
each pressure at least once every minute. The recording system shall be 
capable of resolving time to 15 s and capable of 
resolving pressure to 0.1 inches of water. The 
pressure recording system (recorder and sensor) shall have an accuracy 
of 1.0 inch of water. The recorder (data 
processor) shall have a time accuracy of 15 s and 
a precision of 15 s. The pressure transducer shall 
be installed to measure the pressure in the vapor space of the fuel 
tank.
    (g) Purge blower. One or more portable or fixed blowers shall be 
used to purge the enclosure. The blowers shall have sufficient flow 
capacity to reduce the enclosure hydrocarbon and/or methanol 
concentration from the test level to the ambient level between tests. 
Actual flow capacity will depend upon the time available between tests.
    (h) Mixing blower. Blowers or fans shall be used to mix the 
enclosure contents during evaporative emission testing. The inlets and 
outlets of the air circulation blower(s) shall be configured to provide 
a well dispersed air circulation pattern that produces effective 
internal mixing and avoids significant temperature or hydrocarbon 
stratification. Maintenance of uniform concentrations throughout the 
enclosure is important to the accuracy of testing.
    (1) Diurnal emission test. Blowers or fans shall have a capacity of 
0.80.2 cfm per cubic foot of the nominal enclosure 
volume for mixing in the enclosure. Additional fans may be used to 
maintain a minimum wind speed of 5 mph (8 km/h) under the fuel tank of 
the test vehicle.
    (2) Running loss test. Blowers or fans shall have a total capacity 
of at least 1.0 cfm per cubic foot of the nominal enclosure volume.
    (3) Hot soak test. Blowers or fans must have a capacity of 0.80.2 cfm per cubic foot of the nominal enclosure volume. 
Circulated air shall not be aimed directly at the vehicle.
    (i) Point-source running loss measurement facility. Some system 
requirements pertain specifically to running loss testing by the point-
source method, in which emissions from potential sources are collected 
and routed to a sampling system. Emissions are sampled with the same 
equipment and techniques as for exhaust emission measurement. The test 
environment must contain a dynamometer that meets the requirements of 
Sec.86.108. During the running loss test, ambient temperatures must be 
maintained at 955 [deg]F (952 [deg]F on average). An air or oxygen cylinder with an 
attached self-contained breathing apparatus may be provided for the 
vehicle operator.

[[Page 629]]

    (1) The running loss vapor vent collection system shall be 
configured to collect all running loss emissions from each of the 
discrete point sources that function as vehicle fuel system vapor vents, 
and transport the collected vapor emissions to a CFV- or PDP-based 
dilution and measurement system. The collection system shall consist of 
a collector at each vehicle vapor vent, lengths of heated sample line 
connecting each collector to the inlet of the heated sample pump, and 
lengths of heated sample line connecting the outlet of the heated sample 
pump to the inlet of the running loss fuel vapor sampling system. Up to 
3 feet of unheated line connecting each of the vapor collectors to the 
heated sample lines shall be allowed. Each heated sample pump and its 
associated sample lines shall be maintained at a temperature between 175 
[deg]F and 200 [deg]F to prevent condensation of fuel vapor in the 
sample lines. The heated sample pump(s) and its associated flow controls 
shall be configured and operated to draw a flow of ambient air into each 
collector at a flow rate of at least 0.67 cfm. The flow controls on each 
heated sampling system shall include an indicating flow meter that 
provides an alarm output to the data recording system if the flow rate 
drops below 0.67 cfm by more than 5 percent. The collector inlet for 
each discrete vapor vent shall be placed in proximity to the vent as 
necessary to capture any fuel vapor emissions without significantly 
affecting flow or pressure of the normal action of the vent. The 
collector inlets shall be designed to interface with the configuration 
and orientation of each specific vapor vent. For vapor vents that 
terminate in a tube or hose barb, a short length of tubing of an inside 
diameter larger throughout its length than the inside diameter of the 
vent outlet may be used to extend the vent into the mouth of the 
collector. For those vapor vent designs that are not compatible with 
such collector configurations, the vehicle manufacturer shall supply a 
collector that is configured to interface with the vapor vent design and 
that terminates in a fitting that is capable of capturing all vapor 
emitted from the vent. The Administrator may test for running losses by 
the point-source method without heating sample lines or pumps.
    (2) The running loss fuel vapor sampling system shall be a CFV- or 
PDP-based dilution and measurement system that further dilutes the 
running loss fuel vapors collected by the vapor vent collection 
system(s) with ambient air, collects continuously proportional samples 
of the diluted running loss vapors and dilution air in sample bags, and 
measures the total dilute flow through the sampling system over each 
test interval. In practice, the system shall be configured and operated 
in a manner that is directly analogous to an exhaust emissions constant 
volume sampling system, except that the input flow to the system is the 
flow from the running loss vapor vent collection system(s) instead of 
vehicle exhaust flow. The system shall be configured and operated to 
meet the following requirements:
    (i) The running loss fuel vapor sampling system shall be designed to 
measure the true mass of fuel vapor emissions collected by the running 
loss vapor vent collection system from the specified fuel vapor vents. 
The total volume of the mixture of running loss emissions and dilution 
air shall be measured and a continuously proportioned sample of volume 
shall be collected for analysis. Mass emissions shall be determined from 
the sample concentration and total flow over the test period.
    (ii) The PDP-CVS shall consist of a dilution air filter and mixing 
assembly, heat exchanger, positive-displacement pump, sampling system, 
and associated valves, pressure and temperature sensors. The PDP-CVS 
shall conform to the following requirements:
    (A) The gas mixture temperature, measured at a point immediately 
ahead of the positive-displacement pump, shall be within 10 [deg]F of the designed operating temperature at the 
start of the test. The gas mixture temperature variation from its value 
at the start of the test shall be limited to 10 
[deg]F during the entire test. The temperature measuring system shall 
have an accuracy and precision of 2 [deg]F.
    (B) The pressure gauges shall have an accuracy and precision of 
1.6 inches of water (0.4 
kPa).

[[Page 630]]

    (C) The flow capacity of the CVS shall not exceed 350 cfm.
    (D) Sample collection bags for dilution air and running loss fuel 
vapor samples shall be sufficient size so as not to impede sample flow.
    (iii) The CFV sample system shall consist of a dilution air filter 
and mixing assembly, a sampling venturi, a critical flow venturi, a 
sampling system and assorted valves, and pressure and temperature 
sensors. The CFV sample system shall conform to the following 
requirements:
    (A) The temperature measuring system shall have an accuracy and 
precision of 2 [deg]F and a response time of 0.100 
seconds of 62.5 percent of a temperature change (as measured in hot 
silicone oil).
    (B) The pressure measuring system shall have an accuracy and 
precision of 1.6 inches of water (0.4 kPa).
    (C) The flow capacity of the CVS shall not exceed 350 cfm.
    (D) Sample collection bags for dilution air and running loss fuel 
vapor samples shall be of sufficient size so as not to impede sample 
flow.
    (3) An on-line computer system or strip-chart recorder shall be used 
to record the following additional parameters during the running loss 
test sequence:
    (i) CFV (if used) inlet temperature and pressure.
    (ii) PDP (if used) inlet temperature, pressure, and differential 
pressure.

Sec.86.107-98  Sampling and analytical system.

    Section 86.107-98 includes text that specifies requirements that 
differ from Sec.86.107-96. Where a paragraph in Sec.86.107-96 is 
identical and applicable to Sec.86.107-98, this may be indicated by 
specifying the corresponding paragraph and the statement ``[Reserved]. 
For guidance see Sec.86.107-96.'' Where a corresponding paragraph of 
Sec.86.107-96 is not applicable, this is indicated by the statement 
``[Reserved].''
    (a)(1)-(a)(3) [Reserved]. For guidance see Sec.86.107-96.
    (a)(4) Refueling emissions test. The requirements detailed in Sec.
86.107-90 (a)(1) shall apply. Alternatively, an enclosure meeting the 
specifications detailed in Sec.86.107-96 (a)(1), (2), or (3) may be 
used if approved in advance by the Administrator. In addition, the 
enclosure shall have one or more access ports leading to flexible, 
automatic sealing boots, in the wall(s) of the enclosure. The function 
of the access port(s) and boots shall be to allow fueling of the test 
vehicle from a fuel nozzle and hose located outside of the enclosure, 
with only the spout of the nozzle passing through the automatic sealing 
opening of the boot during fueling. There shall be no loss in the gas 
tightness of the enclosure at the opening of the boot either when the 
nozzle is inserted or when the nozzle is not inserted.
    (b)-(d) [Reserved]. For guidance see Sec.86.107-96.
    (e) Temperature recording system--(1) For all emission testing. A 
strip chart potentiometric recorder, an on-line computer system, or 
other suitable means shall be used to record enclosure ambient 
temperature during all evaporative emission test segments, as well as 
vehicle fuel tank temperature during the running loss test. The 
recording system shall record each temperature at least once every 
minute. The recording system shall be capable of resolving time to 
15 s and capable of resolving temperature to 
0.75 [deg]F (0.42 [deg]C). 
The temperature recording system (recorder and sensor) shall have an 
accuracy of 3 [deg]F (1.7 
[deg]C). The recorder (data processor) shall have a time accuracy of 
15 s and a precision of 15 
s. Enclosures shall be equipped with two ambient temperature sensors, 
connected to provide one average output, located 3 feet above the floor 
at the approximate mid-length of each side wall of the enclosure and 
within 3 to 12 inches of each side wall. For diurnal emission testing, 
an additional temperature sensor shall be located underneath the vehicle 
to provide a temperature measurement representative of the temperature 
of the air under the fuel tank. For running loss testing, an ambient 
temperature sensor shall be located at the inlet to the fan that 
provides engine cooling. Manufacturers shall arrange that vehicles 
furnished

[[Page 631]]

for testing at federal certification facilities be equipped with 
temperature sensors for measurement of fuel tank temperature. Vehicles 
shall be equipped with 2 temperature sensors installed to provide an 
average liquid fuel temperature. The temperature sensors shall be placed 
to measure the temperature at the mid-volume of the liquid fuel at a 
fill level of 40 percent of nominal tank capacity. An additional 
temperature sensor may be placed to measure vapor temperatures 
approximately at the mid-volume of the vapor space, though measurement 
of vapor temperatures is optional during the running loss test. In-tank 
temperature sensors are not required for the supplemental two-diurnal 
test sequence specified in Sec.86.130-96 or for the refueling test 
specified in Sec.86.151-98.
    (2) Refueling emission testing only. In addition to the enclosure 
ambient temperature recording system described in paragraph (e)(1) of 
this section, strip chart recorder(s) or automatic data processor shall 
be used to record vehicle soak area ambient temperature and dispensed 
fuel temperature at the nozzle during the test. The temperature 
recorder(s) or data processor shall record each temperature at least 
once every 20 seconds (the soak area ambient temperature recorder may be 
a continuous recording system). The recording system shall be capable of 
resolving time to 15s and be capable of resolving 
temperature to 0.75 [deg]F (0.42 [deg]C).
    (f)-(h)(3) [Reserved]. For guidance see Sec.86.107-96.
    (h)(4) Refueling emission test. Blowers or fans must have a capacity 
of 0.80.2 cfm per cubic foot of the nominal 
enclosure volume. Circulated air shall not be aimed directly at the 
vehicle.
    (5) Spilled fuel mixing blower; refueling emission test. An 
explosion-proof blower of 100-200 ft\3\/min (2.8-5.7 m\3\/min) capacity 
is required to enhance mixing of vapors from spilled fuel through the 
enclosure atmosphere during tests. The discharge from this blower shall 
be directed toward the region of the enclosure floor where fuel spillage 
during fueling may occur.
    (i) [Reserved]. For guidance see Sec.86.107-96.
    (j) Refueling equipment. The refueling equipment shall consist of a 
fuel delivery system with temperature control equipment, fuel flow 
safety switch, dispensing pump, hose, nozzle and a meter to measure the 
dispensed fuel volume. The dispensing nozzle shall be a commercial 
model, not equipped with vapor recovery hardware. A fuel recirculation 
system may be utilized to avoid trapping of unheated fuel in the hose. 
The fuel delivery system must be capable of delivering fuel at 671.5 [deg]F (19.40.8 [deg]C) and a 
constant flow rate between 4.2 and 9.8 gal/min (15.9 and 37.1 liter/min) 
with a tolerance of 0.3 gal/min (1.1 liter/min) during the refueling emissions 
measurement phase of the test. The accuracy of the meter for measuring 
the dispensed fuel volume shall be 2 percent at 
the test flow rate.

Sec.86.108-00  Dynamometer.

    (a) The dynamometer shall simulate the road load force and inertia 
specified for the vehicle being tested, and shall determine the distance 
traveled during each phase of the test procedure.
    (b) Two types of dynamometer roll configurations are currently 
approved by the Administrator:
    (1) A small twin-roll dynamometer that has a nominal roll diameter 
of 8.65 inches and a nominal roll spacing of 17 inches; and
    (2)(i) An electric dynamometer that has a single roll with a nominal 
diameter of 48 inches (1.20 to 1.25 meters).
    (ii)(A) The dynamometer must be capable of dynamically controlling 
inertia load during the US06 test cycle as a function of a vehicle 
throttle position signal if a manufacturer desires using the following 
test option. Any time the duration of throttle operation greater than or 
equal to 85% of wide open throttle (WOT) is greater than or equal to 
eight seconds, the test inertia load may be adjusted during any of five 
EPA specified acceleration events by an amount of load that will 
eliminate additional throttle operation greater than or equal to 85% of 
WOT.

[[Page 632]]

    (B)(1) The specific US06 schedule accelerations time periods where 
inertia load adjustments may be applied are:
    (i) 49 through 69 seconds;
    (ii) 83 through 97 seconds;
    (iii) 135 through 165 seconds;
    (iv) 315 through 335 seconds; and
    (v) 568 through 583 seconds.
    (2) During these five time intervals when inertia load adjustment is 
occurring, inertia load adjustment is discontinued when throttle 
operation is less than 85% of WOT or at the end of the specified time 
interval.
    (C) Each type of generic application for implementing this concept 
must receive the Administrator's approval before a manufacturer may use 
these inertia adjustments for official US06 schedule certification 
tests.
    (c) Other dynamometer configurations may be used for testing if it 
can be demonstrated that the simulated road load power and inertia are 
equivalent, and if approved in advance by the Administrator.
    (d) An electric dynamometer meeting the requirements of paragraph 
(b)(2) of this section, or a dynamometer approved as equivalent under 
paragraph (c) of this section, must be used for all types of emission 
testing in the following situations.
    (1)(i) Gasoline vehicles which are part of an engine family which is 
designated to meet the phase-in of SFTP compliance required under the 
implementation schedule of table A00-1 of Sec.86.000-08, or table A00-
3, or table A00-5 of Sec.86.000-09.
    (ii) Diesel LDVs and LDT1s which are part of an engine family which 
is designated to meet the phase-in of SFTP compliance required under the 
implementation schedule of table A00-1 of Sec.86.000-08, or table A00-
3, or table A00-5 of Sec.86.000-09.
    (2) Starting with the 2002 model year, any light-duty vehicle or 
light light-duty truck which uses any regulated fuel.
    (3) Starting with the 2004 model year, any heavy light-duty truck 
which uses any regulated fuel.

[61 FR 54890, Oct. 22, 1996]



Sec.86.109-94  Exhaust gas sampling system; Otto-cycle vehicles not
requiring particulate emission measurements.

    (a)(1) General. The exhaust gas sampling system described in this 
paragraph is designed to measure the true mass of gaseous emissions in 
the exhaust of either Otto-cycle light-duty vehicles or light-duty 
trucks which are waived from requirements for the measurement of 
particulate emissions. In the CVS concept of measuring mass emissions, 
two conditions must be satisfied: the total volume of the mixture of 
exhaust and dilution air must be measured, and a continuously 
proportioned volume of sample must be collected for analysis. Mass 
emissions are determined from the sample concentration and total flow 
over the test period.
    (2) Vehicle tailpipe to CVS Duct. For methanol-fueled vehicles, 
cooling of the exhaust gases in the duct connecting the vehicle tailpipe 
to the CVS shall be minimized. This may be accomplished by:
    (i) Using a duct of unrestricted length maintained at a temperature 
above the maximum dew point of the exhaust, but below 250 [deg]F (121 
[deg]C); heating and possibly cooling capabilities are required; or
    (ii) Using a short duct (up to 12 feet long) constructed of smooth 
wall pipe with a minimum of flexible sections, maintained at a 
temperature above the maximum dew point of the exhaust, but below 250 
[deg]F (121 [deg]C), prior to the test and during the 10 minute hot soak 
segment and uninsulated during the test (insulation may remain in place 
and/or heating may occur during testing provided maximum temperature is 
not exceeded); or
    (iii) Using smooth wall duct less than five feet long with no 
required heating. A maximum of two short flexible connectors are allowed 
under this option; or
    (iv) Omitting the duct and performing the exhaust gas dilution 
function at the vehicle tailpipe exit.
    (3) Positive displacement pump. The Positive Displacement Pump-
Constant Volume Sampler (PDP-CVS), Figure B94-1 satisfies the first 
condition by metering at a constant temperature and pressure through the 
pump. The

[[Page 633]]

total volume is measured by counting the revolutions made by the 
calibrated positive displacement pump. The proportional samples for the 
bag sample, and for methanol-fueled vehicles, the methanol sample 
(Figure B94-2) and the formaldehyde sample (Figure B94-3), are achieved 
by sampling at a constant flow rate. For methanol-fueled vehicles, the 
sample lines for the methanol and formaldehyde samples are heated to 
prevent condensation. The temperature of the sample lines shall be more 
than 5 [deg]F (3 [deg]C) above the maximum dew point of the sample, but 
below 250 [deg]F (121 [deg]C). (Note: For 1990 through 1994 model year 
methanol-fueled vehicles, methanol and formaldehyde sampling may be 
omitted provided the bag sample (hydrocarbons and methanol) is analyzed 
using a HFID calibrated with methanol.)

    (4) Critical flow venturi. The operation of the Critical Flow 
Venturi-Constant Volume Sampler (CFV-CVS) sample system, Figure B94-4, 
is based upon the principles of fluid dynamics associated with critical 
flow. Proportional sampling throughout temperature excursions is 
maintained by use of small

[[Page 637]]

CFVs in the sample lines (for methanol-fueled vehicles, one line 
supplies sample for the bag sample, another line supplies sample for the 
methanol sample, and a third line supplies sample for the formaldehyde 
sample.) The methanol and formaldehyde sample lines are heated to 
prevent condensation. The temperature of the sample lines shall be more 
than 5 [deg]F (3 [deg]C) above the maximum dew point of the sample, but 
below 250 [deg]F (121 [deg]C). Care should be taken to ensure that the 
CFVs of the sample probes are not heated since heating of the CFVs would 
cause loss of proportionality. The variable mixture flow rate is 
maintained at sonic velocity, is inversely proportional to the square 
root of the gas temperature, and is computed continuously. Since the 
pressure and temperature are the same at all venturi inlets, the sample 
volume is proportional to the total volume. (Note: For 1990 through 1994 
model year methanol-fueled vehicles, methanol and formaldehyde sampling 
may be omitted provided the bag sample (hydrocarbons and methanol) is 
analyzed using a HFID calibrated with methanol.)

[[Page 638]]

[GRAPHIC] [TIFF OMITTED] TR06OC93.148

    (5) Electronic flow control. The Critical Flow Venturi-Electronic 
Flow Control-Constant Volume Sampler (CFV-EFC-CVS) system is identical 
to the CFV-CVS system described in paragraphs (a)(4) and (c) of this 
section, except that it maintains proportional sampling for methanol and 
formaldehyde by measuring the CVS flow rate, and electronically 
controlling sample flow rates. For methanol-fueled vehicles, the samples 
lines for the methanol and formaldehyde samples are heated to prevent 
condensation. The temperature of the sample lines shall be more than 5 
[deg]F (3 [deg]C) above the maximum dew

[[Page 639]]

point of the sample, but below 250 [deg]F (121 [deg]C).
    (6) Other systems. Other sampling systems may be used if shown to 
yield equivalent or superior results, and if approved in advance by the 
Administrator.
    (b) Component description, PDP-CVS. The PDP-CVS, Figure B94-1, 
consists of a dilution air filter and mixing assembly, heat exchanger, 
positive displacement pump, sampling systems (see Figure B94-2 for 
methanol sampling system and Figure B94-3 for formaldehyde sampling 
system) sampling lines which are heated to a temperature that is more 
than 5 [deg]F (3 [deg]C) above the maximum dew point of the sample, but 
below 250 [deg]F (121 [deg]C) in the case of the methanol-fueled 
vehicles (heating of the sample lines may be omitted, provided the 
methanol and formaldehyde sample collection systems are close coupled to 
the probes thereby preventing loss of sample due to cooling and 
resulting condensation in the sample lines), and associated valves, 
pressure and temperature sensors. The PDP-CVS shall conform to the 
following requirements:
    (1) Static pressure variations at the tailpipe(s) of the vehicle 
shall remain within 5 inches of water (1.2 kPa) of 
the static pressure variations measured during a dynamometer driving 
cycle with no connection to the tailpipe(s). (Sampling systems capable 
of maintaining the static pressure to within 1 
inch of water (0.25 kPa) will be used by the Administrator if a written 
request substantiates the need for this closer tolerance.)
    (2) The gas mixture temperature, measured at a point immediately 
ahead of the positive displacement pump, shall be within 10 [deg]F (5.6 [deg]C) of the 
designed operating temperature at the start of the test. The gas mixture 
temperature variation from its value at the start of the test shall be 
limited to 10 [deg]F (5.6 
[deg]C) during the entire test. The temperature measuring system shall 
have an accuracy and precision of 2 [deg]F (1.1 
[deg]C).
    (3) The pressure gauges shall have an accuracy and precision of 
1.6 inches of water (0.4 kPa).
    (4) The flow capacity of the CVS shall be large enough to completely 
eliminate water condensation in the dilution and sampling systems. (300 
to 350 cfm (0.142 to 0.165 m\3\/s) is sufficient for most petroleum-
fueled vehicles. Higher flow rates are required for methanol-fueled 
vehicles and may be required for natural gas-fueled and liquefied 
petroleum gas-fueled vehicles. Procedures for determining CVS flow rates 
are detailed in ``Calculation of Emissions and Fuel Economy When Using 
Alternative Fuels,'' EPA 460/3-83-009.) (Copies may be obtained from 
U.S. Department of Commerce, NTIS, Springfield, Virginia 22161; order 
PB84104702.) Dehumidifying the dilution air before entering the CVS is 
allowed. Hearing the dilution air is also allowed, provided:
    (i) The air (or air plus exhaust gas) temperature does not exceed 
250 [deg]F.
    (ii) Calculation of the CVS flow rate necessary to prevent water 
condensation is based on the lowest temperature encountered in the CVS 
prior to sampling. (It is recommended that the CVS system be insulated 
when heated dilution air is used.)
    (iii) The dilution ratio is sufficiently high to prevent 
condensation in bag samples as they cool to room temperature.
    (5) Sample collection bags for dilution air and exhaust samples 
shall be of sufficient size so as not to impede sample flow. A single 
dilution air sample, covering the total test period, may be collected 
for the determination of methanol and formaldehyde background (methanol-
fueled vehicles).
    (6) The methanol sample collection system and the formaldehyde 
sample collection system shall each be of sufficient capacity so as to 
collect samples of adequate size for analysis without significant impact 
on the volume of dilute exhaust passing through the PDP. The systems 
shall also comply with the following requirements that apply to the 
design of the systems, not to individual tests.
    (i) The methanol system shall be designed such that, if a test 
vehicle emitted the maximum allowable level of methanol (based on all 
applicable standards) during the first phase of the test, the measured 
concentration in the primary impinger would exceed either 25 mg/l or a 
concentration equal to 25 times the limit of detection for the

[[Page 640]]

GC analyzer. Sampling systems for all phases shall be identical.
    (ii) The formaldehyde system shall be designed such that, if a test 
vehicle emitted formaldehyde at a rate equal to twenty percent of the 
maximum allowable level of NMHCE (i.e., 0.05 g/mi for a 0.25 g/mi NMHCE 
standard), or the maximum formaldehyde level allowed by a specific 
formaldehyde standard, whichever is less, during the first phase of the 
test, the concentration of formaldehyde in the DNPH solution of the 
primary impinger, or solution resulting from the extraction of the DNPH 
cartridge, shall exceed either 2.5 mg/l or a concentration equal to 25 
times the limit of detection for the HPLC analyzer. Sampling systems for 
all phases shall be identical.
    (iii) The methanol and formaldehyde impinger systems shall be 
designed such that the primary impinger collects at least 90 percent of 
the analyte in the samples. The remaining analyte shall be collected by 
the secondary impinger. This requirement does not apply to dilution air 
samples, since they do not require secondary impingers, or to samples in 
which the concentrations approach the limit of detection.
    (c) Component description, CFV-CVS. The CFV-CVS sample system, 
Figure B94-4, consists of a dilution air filter and mixing assembly, a 
cyclone particulate separator, unheated sampling venturies for the bag 
samples, and for the methanol and formaldehyde samples from methanol-
fueled vehicles, samples lines heated to a temperature that is more than 
5 [deg]F (3 [deg]C) above the maximum dew point of the sample, but below 
250 [deg]F (121 [deg]C) for the methanol and formaldehyde samples from 
methanol fueled vehicles (heating of the sample lines may be omitted 
provided, the methanol and formaldehyde sample collection systems are 
close coupled to the probes thereby preventing loss of sample due to 
cooling and resulting condensation in the sample lines), a critical flow 
venturi, and assorted valves, and pressure and temperature sensors. The 
CFV sample system shall conform to the following requirements:
    (1) Static pressure variations at the tailpipe(s) of the vehicle 
shall remain within 5 inches of water (1.2 kPa) of 
the static pressure variations measured during a dynamometer driving 
cycle with no connection to the tailpipe(s). (Sampling systems capable 
of maintaining the static pressure to within 1 
inch of water (0.25 kPa) will be used by the Administrator if a written 
request substantiates the need for this closer tolerance.)
    (2) The temperature measuring system shall have an accuracy and 
precision of 2 [deg]F (1.1 [deg]C) and a response 
time of 0.100 seconds to 62.5 percent of a temperature change (as 
measured in hot silicone oil).
    (3) The pressure measuring system shall have an accuracy and 
precision of 1.6 inches of water (0.4 kPa).
    (4) The flow capacity of the CVS shall be large enough to completely 
eliminate water condensation in the dilution and sampling systems. (300 
to 350 cfm (0.142 to 0.165 m\3\/s) is sufficient for most petroleum-
fueled vehicles. Higher flow rates are required for methanol-fueled 
vehicles and may be required for natural gas-fueled and liquefied 
petroleum gas-fueled vehicles. Procedures for determining CVS flow rates 
are detailed in ``Calculation of Emissions and Fuel Economy When Using 
Alternative Fuels,'' EPA 460/3-83-009.) Dehumidifying the dilution air 
before entering the CVS is allowed. Heating the dilution air is also 
allowed, provided:
    (i) The air (or air plus exhaust gas) temperature does not exceed 
250 [deg]F (121 [deg]C).
    (ii) Calculation of the CVS flow rate necessary to prevent water 
condensation is based on the lowest temperature encountered in the CVS 
prior to sampling. (It is recommended that the CVS system be insulated 
when heated dilution air is used.)
    (iii) The dilution ratio is sufficiently high to prevent 
condensation in bag samples as they cool to room temperature.
    (5) Sample collection bags for dilution air and exhaust samples 
shall be of sufficient size so as not to impede sample flow. A single 
dilution air sample, covering the total test period, may be collected 
for the determination of methanol and formaldehyde background (methanol-
fueled vehicles).
    (6) The methanol sample collection system and the formaldehyde 
sample

[[Page 641]]

collection system shall each be of sufficient capacity so as to collect 
samples of adequate size for analysis without significant impact on the 
volume of dilute exhaust passing through the CVS. The systems shall also 
comply with the following requirements that apply to the design of the 
systems, not to individual tests.
    (i) The methanol system shall be designed such that, if a test 
vehicle emitted the maximum allowable level of methanol (based on all 
applicable standards) during the first phase of the test, the measured 
concentration in the primary impinger would exceed either 25 mg/l or a 
concentration equal to 25 times the limit of detection for the GC 
analyzer. Sampling systems for all phases shall be identical.
    (ii) The formaldehyde system shall be designed such that, if a test 
vehicle emitted formaldehyde at a rate equal to twenty percent of the 
maximum allowable level of NMHCE (i.e., 0.05 g/mi for a 0.25 g/mi NMHCE 
standard), or the maximum formaldehyde level allowed by a specific 
formaldehyde standard, whichever is less, during the first phase of the 
test, the concentration of formaldehyde in the DNPH solution of the 
primary impinger, or solution resulting from the extraction of the DNPH 
cartridge, shall exceed either 2.5 mg/l or a concentration equal to 25 
times the limit of detection for the HPLC analyzer. Sampling systems for 
all phases shall be identical.
    (iii) The methanol and formaldehyde systems shall be designed such 
that the primary impinger collects at least 90 percent of the analyte in 
the samples. The remaining analyte shall be collected by the secondary 
impinger. This requirement does not apply to dilution air samples, since 
they do not require secondary impingers, or to samples in which the 
concentrations approach the limit of detection.
    (d) Component description, CFV-EFC-CVS. The CVS sample system is 
identical to the system described in paragraph (c) of this section, plus 
includes a means of electronically measuring the CVS flow rate, and 
electronic mass flow controllers for the methanol and formaldehyde 
sample lines. The EFC sample system shall conform to all of the 
requirements listed in paragraph (c), except that the methanol and 
formaldehyde samples must both be drawn from a static probe. It also 
must comply with the following additional requirements:
    (1) The ratio of the CVS mass flow rate to the sample mass flow rate 
shall not deviate from the design ratio by more than 5 percent. (The volumetric sample flow rate shall be 
varied inversely with the square root of the bulk stream temperature.)
    (2) Flow meters to totalize sample volumes for methanol and/or 
formaldehyde samples shall meet the accuracy specifications of Sec.
86.120. Total sample volumes may be obtained from the flow controllers, 
provided that the controllers meet the accuracy specifications of Sec.
86.120.

Sec.86.110-94  Exhaust gas sampling system; diesel-cycle vehicles,
and Otto-cycle vehicles requiring particulate emissions measurements.

    Section 86.110-94 includes text that specifies requirements that 
differ from Sec.86.110-90. Where a paragraph in Sec.86.110-90 is 
identical and applicable to Sec.86.110-94, this may be indicated by 
specifying the corresponding paragraph and the statement ``[Reserved]. 
For guidance see Sec.86.110-90.'' Where a corresponding paragraph of 
Sec.86.110-90 is not applicable, this is indicated by the statement 
``[Reserved].''
    (a) General. The exhaust gas sampling system described in this 
paragraph is designed to measure the true mass of both gaseous and 
particulate emissions in the exhaust of either diesel-cycle or Otto-
cycle light-duty vehicles and light-duty trucks. This system utilizes 
the CVS concept (described in Sec.86.109) of measuring mass emissions. 
The mass of gaseous emissions is determined from the sample 
concentration and total flow over the test period. The mass of 
particulate emissions is determined from a proportional mass sample 
collected on a filter and from the total flow over the test period. 
General requirements are as follows:
    (1) This sampling system requires the use of a PDP-CVS, CFV-CVS (or 
a CFV-EFC-CVS), sample system with heat

[[Page 642]]

exchanger connected to a dilution tunnel. The heat exchanger is not 
required for the CFV-CVS or EFC-CFV-CVS if electronic flow controllers 
are used to maintain proportionality for the particulate sample. Figure 
B94-5 is a schematic drawing of the PDP system. Figure B94-6 is a 
schematic drawing of the CFV-CVS system. (Methanol-fueled Otto-cycle 
vehicles may be tested using this test equipment, without measuring 
particulate emissions.)

    (2) Bag, continuous HFID (required for petroleum-fueled diesel-cycle 
and optional for methanol-fueled, natural gas-fueled and liquefied 
petroleum gas-fueled diesel-cycle vehicles), and particulate sampling 
capabilities as shown in Figure B94-5 (or Figure B94-6) are required to 
provide both gaseous and particulate emissions sampling capabilities 
from a single system.
    (3) Petroleum-fueled diesel-cycle vehicles require a heated flame 
ionization detector (HFID) (375 [deg]20 [deg]F 
(191 [deg]11 [deg]C)) sample for total hydrocarbon 
(THC) analysis. The HFID sample must

[[Page 644]]

be taken directly from the diluted exhaust stream through a heated probe 
in the dilution tunnel.
    (4) Methanol-fueled vehicles require the use of a heated flame 
ionization detector (HFID) (235 [deg]15 [deg]F 
(113 [deg]8 [deg]C)) for hydrocarbon analysis. 
With an HFID, the hydrocarbon analysis can be made on the bag sample and 
the methanol and formaldehyde analyses are performed on the samples 
collected for these purposes (Figures B94-2 and B94-3).

    Note: For 1990 through 1994 model year methanol-fueled vehicles, 
methanol and formaldehyde sampling may be omitted provided the bag 
sample is analyzed using a HFID calibrated with methanol.

    (5) For methanol-fueled vehicles, the vehicle tailpipe-to-dilution 
tunnel connection shall be made by:
    (i) A tailpipe to dilution tunnel duct of unrestricted length 
maintained at a temperature above the dew point of the mixture, but 
below 250 [deg]F (121 [deg]C) through heating and cooling as required; 
or
    (ii) Using a short duct (up to 12 feet long) constructed of smooth 
wall pipe with a minimum of flexible sections maintained at a 
temperature above the dew point of the mixture, but below 250 [deg]F 
(121 [deg]C) prior to the test and during breaks in testing (insulation 
may remain in place and or heating may occur during the testing provided 
the maximum temperature is not exceeded); or
    (iii) Using smooth wall duct less than five feet long with no 
required heating. A maximum of two short flexible connectors are allowed 
under this option; or
    (iv) By omitting the duct and performing the exhaust gas dilution 
function at the vehicle tailpipe exit.
    (6) For natural gas-fueled and liquefied petroleum gas-fueled diesel 
vehicles either a heated flame ionization detector (HFID) 
[375[deg]20 [deg]F (191[deg]11 [deg]C)] or a non-heated flame ionization detector 
may be used for hydrocarbon analysis.
    (7) Since various configurations can produce equivalent results, 
exact conformance with these drawings is not required. Additional 
components such as instruments, valves, solenoids, pumps, and switches 
may be used to provide additional information and coordinate the 
functions of the component systems.
    (8) Other sampling systems may be used if shown to yield equivalent 
or superior results and if approved in advance by the Administrator.
    (b) Component description--petroleum-fueled, natural gas-fueled and 
liquefied petroleum gas-fueled vehicles. The components necessary for 
petroleum-fueled, natural gas-fueled and liquefied petroleum gas-fueled 
vehicle exhaust sampling shall meet the following requirements:

particulate sampling system, and shall conform to all of the 
requirements listed for the exhaust gas PDP-CVS (Sec.86.109(b)), with 
one exception: a flow rate of sufficient volume is required to maintain 
the diluted exhaust stream, from which the particulate sample flow is 
taken, at a temperature of 125 [deg]F (52 [deg]C) or less.
    (2) The CFV sample system, Figure B94-6, shall contain a 
proportional particulate sampling system, and shall conform to all of 
the requirements listed for the exhaust gas CFV sample system (Sec.
86.109(c)), except for the following:
    (i) A flow rate of sufficient volume is required to maintain the 
diluted exhaust stream, from which the particulate sample flow is taken, 
at a temperature of 125 [deg]F (52 [deg]C) or less.
    (ii) If a constant volume particulate sample is collected, a heat 
exchanger is required.
    (iii) If a heat exchanger is used, the gas mixture temperature, 
measured at a point immediately ahead of the critical flow venturi, 
shall be within 20 [deg]F (11 [deg]C) of the 
designed operating temperature at the start of the test. The gas mixture 
temperature variation from its value at the start of the test shall be

    (3) For gasoline-fueled, natural gas-fueled and liquefied petroleum 
gas-fueled Otto-cycle and petroleum-fueled, natural gas- fueled and

    (17) For methanol-fueled vehicles, bag sampling procedures for the 
measurement of hydrocarbons as described in Sec.86.109 may be 
employed.

    (v) If the ratio is greater than 0.95, base the particulate emission 
calculations on the net weight of the primary filter only.

calculations on the combined net weights of the back-up test filter and 
the primary test filter.

Sec.86.111-94  Exhaust gas analytical system.

    Section 86.111-94 includes text that specifies requirements that 
differ from Sec.86.111-90. Where a paragraph in Sec.86.111-90 is 
identical and applicable to Sec.86.111-94, this may be indicated by 
specifying the corresponding paragraph and the statement ``[Reserved]. 
For guidance see Sec.86.111-90.'' Where a corresponding paragraph of 
Sec.86.111-90 is not applicable, this is indicated by the statement 
``[Reserved].''
    (a) Schematic drawings. Figure B94-7 is a schematic drawing of the 
exhaust gas analytical system for samples from bag sampling systems for 
analysis of total hydrocarbon (THC) (hydrocarbon plus methanol in the 
case of methanol-fueled vehicles), methane (CH4) (for 
vehicles subject to the NMHC and NMHCE standards), carbon monoxide (CO), 
carbon dioxide (CO2), and oxides of nitrogen 
(NOX). The schematic diagram of the continuous THC analysis 
train (and for THC plus methanol for methanol-fueled diesel-cycle 
vehicles) is shown as part of Figure B94-5 (or Figure B94-6). Since 
various configurations can produce accurate results, exact conformance 
with either drawing is not required. Additional components such as 
instruments, valves, solenoids, pumps, and switches may be used to 
provide additional information and coordinate the functions of the 
component systems.

    (b) Major component description. The exhaust gas analytical system, 
Figure B94-7, consists of a flame ionization detector (FID) (heated, 
235[deg] 15 [deg]F (113[deg] 8 [deg]C) for methanol-fueled vehicles) for the 
determination of THC, a methane analyzer (consisting of a gas 
chromatograph combined with a FID) for the determination of 
CH4, non-dispersive infrared analyzers (NDIR) for the 
determination of CO and CO2, a chemiluminescence analyzer 
(CL) for the determination of NOX, and an analyzer meeting 
the requirements specified in 40 CFR 1065.275 for the determination of 
N2O. A heated flame ionization detector (HFID) is used for 
the continuous determination of THC from

[[Page 650]]

petroleum-fueled diesel-cycle vehicles (may also be used with methanol-
fueled diesel-cycle vehicles), Figure B94-5 (or B94-6). The analytical 
system for methanol consists of a gas chromatograph (GC) equipped with a 
flame ionization detector. The analysis for formaldehyde is performed 
using high-pressure liquid chromatography (HPLC) of 2,4-
dinitrophenylhydrazine (DNPH) derivatives using ultraviolet (UV) 
detection. The exhaust gas analytical system shall conform to the 
following requirements:
    (1) The CL requires that the nitrogen dioxide present in the sample 
be converted to nitric oxide before analysis. Other types of analyzers 
may be used if shown to yield equivalent results and if approved in 
advance by the Administrator.
    (2) The carbon monoxide (CO) NDIR analyzer may require a sample 
conditioning column containing CaSO4, or indicating silica 
gel to remove water vapor, and containing ascarite to remove carbon 
dioxide from the CO analysis stream.
    (i) If CO instruments which are essentially free of CO2 
and water vapor interference are used, the use of the conditioning 
column may be deleted, see Sec. Sec.86.122 and 86.144.
    (ii) A CO instrument will be considered to be essentially free of 
CO2 and water vapor interference if its response to a mixture 
of 3 percent CO2 in N2 which has been bubbled 
through water at room temperature produces an equivalent CO response, as 
measured on the most sensitive CO range, which is less than l percent of 
full scale CO concentration on ranges above 300 ppm full scale or less 
than 3 ppm on ranges below 300 ppm full scale, see Sec.86.122.
    (3) For petroleum-fueled diesel vehicles (and if selected, for 
methanol-fueled, natural gas-fueled and liquefied petroleum gas-fueled 
diesel vehicles) a continuous hydrocarbon sample shall be measured using 
a heated analyzer train as shown in Figure B90-5 (or B90-6). The train 
shall include a heated probe, a heated continuous sampling line, a 
heated particulate filter and a heated hydrocarbon instrument (HFID) 
complete with heated pump, filter and flow control system.
    (i) The response time of this instrument shall be less than 1.5 
seconds for 90 percent of full scale response.
    (ii) The continuous THC sample system may use an ``overflow'' zero 
and span system; see Sec.86.140-82(b)(4). In this type of system 
(figures B82-3A and B82-4A), zero or span gas is introduced into the 
heated sample line at a flow rate that exceeds the sample flow rate to 
the HFID. The excess gas overflows the sample probe into the dilution 
tunnel. This method assures that the reference gas enters HFID in the 
same concentration as the injected reference gas and at the same rate as 
the sample exhaust gas. In addition to zero and span checks, it may also 
be used to calibrate the THC analyzer per Sec.86.121-82(b). The 
overflow gas flow rate into the sample line shall be greater than 125 
percent of the HFID flow rate with the CVS blower operating. A lower 
flow rate may be used if it has been experimentally shown to produce 
equivalent results and current documentation is maintained. The overflow 
gases shall enter the heated sample line as close as practicable to the 
outside surface of the dilution tunnel.
    (iii) No other analyzers may draw a sample from the continuous THC 
sample probe, line, or system, unless a common sample pump is used of 
all analyzers and the single sample line system design reflects good 
engineering practice.
    (iv) Sample transport time from sampling point to inlet of 
instrument shall be less than 4 seconds.
    (v) For petroleum-fueled, natural gas-fueled and liquefied petroleum 
gas-fueled diesel vehicles, the sample line and filter shall be heated 
to maintain a sample gas temperature of 375[deg] 10 [deg]F (191[deg] 6 [deg]C) 
before the filter and before the HFID.
    (vi) For methanol-fueled diesel-cycle vehicles, the sample line and 
filter shall be heated to maintain a sample gas temperature of 235 
[deg]15 [deg]F (113 [deg]8 
[deg]C) before the filter and before the HFID.
    (vii) Using a methane analyzer consisting of a gas chromatograph 
combined with a FID, measure methane according to SAE J1151 
(incorporated by reference in Sec.86.1).

    (c) Other analyzers and equipment. Other types of analyzers and 
equipment may be used if shown to yield equivalent or superior results 
and if approved in advance by the Administrator.

Sec.86.112-91  Weighing chamber (or room) and microgram balance
specifications.

    (a) Ambient conditions--(1) Temperature. The temperature of the 
chamber in which the particulate filters are conditioned and weighed 
shall be maintained to within 10 [deg]F (6 [deg]C) 
of a set point between 68 [deg]F (20 [deg]C) and 86 [deg]F (30 [deg]C) 
during all filter conditioning and filter weighing. A continuous 
recording of the temperature is required.
    (2) Humidity. The relative humidity of the chamber in which the 
particulate filters are conditioned and weighed shall be maintained to 
within 10 percent of a set point between 30 and 70 
percent during all filter conditioning and filter weighing. A continuous 
recording of the temperature is required.
    (3) The environment shall be free from any ambient contaminants 
(such as dust) that would settle on the particulate filters during their 
stabilization.
    (4) It is required that two unused reference filters remain in the 
weighing room at all times in covered (to reduce dust contamination) but 
unsealed (to permit humidity exchange) petri dishes. These reference 
filters shall be placed in the same general area as the sample filters. 
These reference filters shall be weighed within 4 hours of, but 
preferably just prior to, the pre- and post-test sample filter 
weighings.
    (5) If the weight of either of the reference filters changes between 
pre- and post-test sample filter weighings by more than 2.0 percent of the test average primary filter loading 
(recommended minimum of 0.5 milligrams) or 0.010 
milligrams, whichever is greater, then the post-test sample filter 
weights are invalid. However, the post-test weighing procedure can be 
repeated to obtain valid weights within the time limits as specified in 
Sec.86.139.
    (6) The reference filters shall be changed at least once per month, 
but never between pre- and post-test weighings of a given sample filter. 
The reference filters shall be the same size and material as the sample 
filters.
    (b) Microgram balance specifications. The microgram balance used to 
determine the weights of all filters shall have a precision (standard 
deviation) and a readability of one microgram.
    (c) Other procedures and equipment. Other procedures and equipment 
may be used if shown to yield equivalent or superior results and if 
approved in advance by the Administrator.

  1,219 m (4000 feet), the specified range is 7.6-8.0 psi (52.4-55.2
  kPa). Calculate dry vapor pressure equivalent, DVPE, based on the
  measured total vapor pressure, pT, using the following equation: DVPE
  (psi) = 0.956 [middot] pT-0.347 (or DVPE (kPa) = 0.956 [middot] pT-
  2.39). DVPE is intended to be equivalent to Reid Vapor Pressure using
  a different test method.

    (2) Manufacturers may use California test fuels, as follows:
    (i) For model year 2014 and earlier vehicles certified for 50-state 
sale, manufacturers may perform exhaust emission tests using California 
Phase 2 gasoline as specified in Chapter 4 of the California Regulatory 
Requirements Applicable to the National Low Emission Vehicle Program, 
October 1996 (incorporated by reference in Sec.86.1). However, the 
Administrator may use or require the use of test fuel meeting the 
specifications in paragraph (a)(1) of this section for confirmatory 
testing, selective enforcement auditing and in-use testing.
    (ii) For model year 2015 and later, manufacturers may certify 50-
state Tier 2 vehicles based on testing used to meet California's LEV III 
standards, subject to the following provisions:
    (A) Manufacturers may perform exhaust and evaporative emission tests 
using California Phase 2 gasoline or California LEV III gasoline. The 
Administrator may use or require the use of test fuel meeting the 
specifications in paragraph (a)(1) of this section for confirmatory 
testing, selective enforcement auditing and in-use testing.
    (B) All evaporative testing with California fuel must be conducted 
with temperatures meeting the specifications adopted by the California 
Air Resources Board.
    (C) The vehicles must also meet exhaust and evaporative emission 
standards at high-altitude conditions as specified in Sec. Sec.
86.1811-17 and 86.1813-17, except that testing is based on the fuel 
specified in paragraph (a)(1) of this section.
    (D) The vehicle must meet the applicable cold temperature standards 
using test fuel specified for cold temperature testing in Sec.86.213.
    (3)(i) Unless otherwise approved by the Administrator, gasoline 
representative of commercial gasoline that will be generally available 
through retail outlets must be used in service accumulation. Unless 
otherwise approved by the Administrator, where the vehicle is to be used 
for evaporative emission durability demonstration, such fuel must 
contain ethanol as required by Sec.86.1824-08(f)(1).
    (ii) Unless otherwise approved by the Administrator, the octane 
rating of the gasoline used must be no higher than 1.0 Retail octane 
number above the lowest octane rating that meets the fuel grade the 
manufacturer will recommend to the ultimate purchaser for the relevant 
production vehicles. If the manufacturer recommends a Retail octane 
number rather than a fuel grade, then the octane rating of the service 
accumulation gasoline can be no higher than 1.0 Retail octane number 
above the recommended Retail octane number. The service accumulation 
gasoline must also have a minimum sensitivity of 7.5 octane numbers, 
where sensitivity is defined as the Research octane number minus the 
Motor octane number.
    (iii) The Reid Vapor Pressure of the gasoline used must be 
characteristic of the motor fuel used during the season in which the 
service accumulation takes place.

[[Page 653]]

    (4) The specification range of the gasoline to be used under this 
paragraph (a) must be reported in accordance with Sec. Sec.86.094-
21(b)(3) and 86.1844-01.

Sec.86.113-15  Fuel specifications.

    Section 86.113-15 includes text that specifies requirements that 
differ from Sec.86.113-94. Where a paragraph in Sec.86.113-94 is 
identical and applicable to Sec.86.113-15, this may be indicated by 
specifying the corresponding paragraph and the statement ``[Reserved]. 
For guidance see Sec.86.113-94.''
    (a) Gasoline fuel. This paragraph (a) describes how to transition to 
an ethanol-blend test fuel for vehicles certified under subpart S of 
this part. You may use the test fuels specified in Sec.86.113-04(a) 
for vehicles that are not yet subject to testing with the new fuel. You 
may use the specified ethanol-blend test fuel anytime earlier than we 
specify as long as you use the corresponding procedures for measuring 
and calculating emission results. See 40 CFR 600.117 for special 
provisions that apply for emission measurements related to fuel economy 
and greenhouse gases. Manufacturers must certify using E10 test fuel as 
specified in 40 CFR part 1065, subpart H, and service accumulation fuel 
meeting applicable specifications as follows:
    (1) Except as allowed under paragraph (a)(2) of this section, Use 
E10 test fuel to demonstrate compliance with the Tier 3 exhaust emission 
standards as specified in Sec.86.1811 and 86.1816, and to demonstrate 
compliance with the Tier 3 evaporative emission standards as specified 
in Sec.86.1813.
    (2) You may use California test fuels to demonstrate compliance with 
Tier 3 emission standards as follows:
    (i) For vehicles certified for 50-state sale, you may instead use 
California Phase 3 gasoline (E10) as adopted in California's LEV III 
program for exhaust emission testing. Through model year 2019, we will 
also use this E10 fuel for any low-altitude exhaust emission testing 
with such vehicles. Starting in model year 2020, we may use test fuel 
meeting either California Phase 3 gasoline (E10) or the gasoline (E10) 
test fuel specified in this paragraph (a). For cold temperature testing 
and for exhaust emission tests at high-altitude conditions, you may 
certify vehicles through model year 2019 based on testing with the 
gasoline (E0) test fuel specified in Sec.86.113-04(a); for such 
vehicles, we may use test fuel meeting either the gasoline (E0) test 
fuel specified in Sec.86.113-04(a) or the gasoline (E10) test fuel 
specified in this paragraph (a).
    (ii) For vehicles that were certified to SULEV exhaust emission 
standards with a 150,000 mile useful life under California's LEV II 
program and that are eligible to use that carryover data for continued 
certification, you may use that carryover data to demonstrate compliance 
with the exhaust emission standards that apply for Bin 30 vehicles under 
Sec.86.1811-17 for model years 2015 through 2019. The test fuel 
specifications that applied for the original emission measurements under 
the LEV II program also apply for any additional exhaust testing under 
the Tier 3 program, including confirmatory testing, selective 
enforcement auditing, and in-use testing. For vehicles certified under 
this paragraph (a)(2)(ii), use the E10 test fuel specified in 40 CFR 
1065.710 for cold temperature testing and high-altitude testing.
    (iii) For vehicles certified for 50-state sale, you may instead use 
California test fuel for evaporative emission testing as follows:
    (A) If you originally certified vehicles in California in model year 
2015 or 2016 to PZEV standards with California Phase 2 gasoline, you may 
use that data with carryover vehicles to certify to the Tier 3 
evaporative emission standards through model year 2019. We will use this 
same fuel to measure diurnal, hot soak, running loss, and SHED rig 
emissions at low-altitude conditions for such vehicles. For refueling, 
spitback, and high-altitude testing, you may use test fuel meeting 
either the gasoline (E0) test fuel specified in Sec.86.113-04(a) or 
the gasoline (E10) test fuel specified in this paragraph (a); we may use 
either of the specified fuels for

[[Page 654]]

our testing. For leak testing, you must use the gasoline (E10) test fuel 
specified in this paragraph (a).
    (B) If you certify vehicles to LEV III standards with California 
Phase 3 gasoline (E10), you may use that collection of data to certify 
to the Tier 3 evaporative emission standards. Through model year 2019, 
we will use this same fuel to measure diurnal, hot soak, running loss, 
SHED rig, and canister bleed emissions (as appropriate) at low-altitude 
conditions; starting in model year 2020, we may use either California 
Phase 3 gasoline (E10) or the gasoline (E10) test fuel specified in this 
paragraph (a) for our testing with such vehicles. For refueling, 
spitback, high-altitude, and leak testing, you must use the gasoline 
(E10) test fuel specified in this paragraph (a), except that you may 
instead use the gasoline (E0) test fuel specified in Sec.86.113-04(a) 
for model year 2015 and 2016; we will use your selected fuel for our 
testing. Note that you may no longer certify vehicles to the Tier 3 
standards based on California's rig-testing procedures after model year 
2021, as described in Sec.86.1813-17(g).
    (C) For evaporative emission testing with California test fuels, 
perform tests based on the test temperatures specified by the California 
Air Resources Board.
    (3) Except as specified in paragraph (a)(2)(iii) of this section and 
in this paragraph (a)(3), use E10 test fuel to demonstrate compliance 
with the refueling and spitback emission standards for any vehicles that 
must be certified to meet the diurnal plus hot soak standards with E10 
test fuel under paragraphs (a)(1) and (2) of this section. You may delay 
using E10 test fuel until model year 2022 for incomplete heavy-duty 
vehicles not certified to refueling emission standards.
    (4) If a vehicle uses E10 test fuel for evaporative emission testing 
and E0 is the applicable test fuel for exhaust emission testing, exhaust 
measurement and reporting requirements apply over the course of the 
evaporative emission test, but the vehicle need not meet the exhaust 
emission standards during the evaporative emission test run.
    (5) For service accumulation, use a commercially available fuel, 
subject to the additional specification in Sec.86.1824-08(f) for 
evaporative emissions.
    (b) through (g) [Reserved]. For guidance see Sec.86.113-94.

Sec.86.115-78  EPA dynamometer driving schedules.

    (a) The driving schedules for the Urban Dynamometer Driving 
Schedule, US06, SC03, and the New York City Cycles are specified in 
appendix I of this part. The driving schedules are defined by a smooth 
trace drawn through the specified speed vs. time relationships. They 
each consist of a distinct non-repetitive series of idle, acceleration, 
cruise, and deceleration modes of various time sequences and rates.
    (b) The driver should attempt to follow the target schedule as 
closely as possible (refer to Sec.86.128 for additional cycle driving 
instructions). The speed tolerance at any given time for these 
schedules, or for a driver's aid chart approved by the Administrator, 
are as follows:
    (1) The upper limit is 2 mph (3.2 km/h) higher than the highest 
point on the trace within 1 second of the given time.
    (2) The lower limit is 2 mph (3.2 km/h) lower than the lowest point 
on the trace within 1 second of the given time.
    (3)(i) Speed variations greater than the tolerances (such as may 
occur during gear changes or braking spikes) are acceptable, provided 
they occur for less than 2 seconds on any occasion and are clearly 
documented as to the time and speed at that point of the driving 
schedule.
    (ii) When conducted to meet the requirements of Sec.86.129-94 or 
Sec.86.153-98(d), up to three additional occurrences of speed 
variations greater than the tolerance are acceptable, provided they 
occur for less than 15 seconds on any occasion, and are clearly 
documented as to the time and speed at that point of the driving 
schedule.
    (4) Speeds lower than those prescribed are acceptable, provided the 
vehicle is operated at maximum available power during such occurrences.
    (5) When conducted to meet the requirements of Sec.86.129-94, 
Sec.86.132-96, Sec.86.146-96, or Sec.86.153-98(d), the speed 
tolerance shall be as specified above, except that the upper and lower 
limits shall be 4 mph (6.4 km/h).
    (c) Figures B78-4(a) and B78-4(b) show the range of acceptable speed 
tolerances for typical points. Figure B78-4(a) is typical of portions of 
the speed curve which are increasing or decreasing throughout the 2-
second time interval. Figure B78-4(b) is typical of portions of the 
speed curve which include a maximum or minimum value.

instruments), methane analyzer, carbon dioxide analyzer, carbon monoxide 
analyzer, and oxides of nitrogen analyzer (certain analyzers may require 
more frequent calibration depending on particular equipment and uses).
    (2) Calibrate the dynamometer. If the dynamometer receives a weekly 
performance check (and remains within calibration) the monthly 
calibration need not be performed.
    (3) Perform an organic gas retention and calibration on the 
evaporative emissions enclosure (see Sec.86.117-90(c)).
    (4) Calibrate the gas meters or flow instrumentation used for 
providing total flow measurement for particulate sampling.
    (5) Check the oxides of nitrogen converter efficiency.
    (d) At least weekly or after any maintenance which could alter 
calibration, the following calibrations and checks shall be performed:

omitted if the dynamometer has been calibrated within the preceding 
month.
    (e) The CVS positive displacement pump or Critical Flow Venturi 
shall be calibrated following initial installation, major maintenance, 
or as necessary when indicated by the CVS system verification (described 
in Sec.86.119).
    (f) Sample conditioning columns, if used in the CO analyzer train, 
should be checked at a frequency consistent with observed column life or 
when the indicator of the column packing begins to show deterioration.
    (g) The Administrator, upon request, may waive the requirement to 
comply with the specified methanol recovery tolerance (e.g., 2 percent in Sec. Sec.86.117-90 and 86.119-90), and/or 
the specified methanol retention tolerance (e.g., 4 percent in Sec.86.117-90), and instead require 
compliance with higher tolerances (not to exceed 6 
percent for recoveries and 8 for retention), 
provided that:
    (1) The Administrator determines that compliance with these 
specified tolerances is not practically feasible; and
    (2) The manufacturer makes information available to the 
Administrator which indicates that the calibration tests and their 
results are consistent with good laboratory practice, and that the 
results are consistent with the results of calibration testing conducted 
by the Administrator.

Sec.86.117-96  Evaporative emission enclosure calibrations.

    The calibration of evaporative emission enclosures consists of three 
parts: initial and periodic determination of enclosure background 
emissions (hydrocarbons and methanol); initial determination of 
enclosure internal volume; and periodic hydrocarbon and methanol 
retention check and calibration. Ethanol retention checks may be 
performed instead of methanol retention checks. Alcohol retentions may 
be omitted if no alcohol-fueled vehicles will be tested in the 
evaporative enclosure. For evaporative and refueling emission tests with 
ethanol-gasoline blends that have less than 25% ethanol by volume, if 
you account for ethanol with a mathematical adjustment as described in 
Sec.86.1813-17(a)(1)(iv) instead of measuring ethanol, the testing 
specifications and diagnostic requirements in this part 86 that are 
specific to ethanol-gasoline blends do not apply. Alternate calibration 
methods may be used if shown to yield equivalent or superior results, 
and if approved in advance by the Administrator; specifically, more 
extreme temperatures may be used for determining calibration without 
affecting the validity of test results.
    (a) Initial and periodic determination of enclosure background 
emissions. Prior to its introduction into service, annually thereafter, 
and after any repair that can affect the enclosure background emissions, 
the enclosure shall be checked to determine that it does not contain 
materials that will themselves

[[Page 660]]

emit hydrocarbons or methanol. When methanol as well as hydrocarbons are 
present in the evaporative enclosure, the HFID hydrocarbon concentration 
measurement includes the partial response of the HFID to methanol plus 
the hydrocarbons. Determination of the HFID response to methanol, Sec.
86.121, prior to its being placed in service is required for the 
determination of hydrocarbons. Proceed as follows:
    (1) Prepare the enclosure. (i) Variable-volume enclosures may be 
operated in either latched or unlatched volume configuration, as 
described in paragraph (b)(1) of this section. Ambient temperatures 
shall be maintained at 963 [deg]F throughout the 
4-hour period.
    (ii) Fixed-volume enclosures may be operated with inlet and outlet 
flow streams either closed or open; if inlet and outlet flow streams are 
open, the air flowing into and out of the enclosure must be monitored in 
accordance with Sec.86.107-96(a)(1)(ii)(B). Ambient temperatures shall 
be maintained at 963 [deg]F throughout the 4-hour 
period.
    (iii) For running loss enclosures ambient temperatures shall be 
maintained at 953 [deg]F throughout the 4-hour 
period. For running loss enclosures designed with a vent for makeup air, 
the enclosure shall be operated with the vent closed.
    (2) The enclosure may be sealed and the mixing fan operated for a 
period of up to 12 hours before the 4-hour background sampling period 
begins.
    (3) Zero and span (calibrate if required) the hydrocarbon analyzer.
    (4) Prior to the background determination, purge the enclosure until 
a stable background hydrocarbon reading is obtained.
    (5) Turn on the mixing blower (if not already on).
    (6) Seal enclosure and measure background hydrocarbon concentration, 
background methanol, temperature, and barometric pressure.
    These are the initial readings CHCi, 
CCH3OHi, and PBi, Ti for the 
enclosure background determination.
    (7) Allow the enclosure to stand undisturbed for four hours.
    (8) Measure the hydrocarbon concentration on the same FID and the 
methanol level. These are the final concentrations, CHCf and 
CCH3OHf. Also measure final temperature and 
barometric pressure.
    (9) Calculate the mass change of methanol, hydrocarbons, and 
hydrocarbons plus methanol in the enclosure according to the equations 
in paragraph (d) of this section.
    (i) Diurnal enclosures. The enclosure background emissions 
(hydrocarbons plus methanol) shall not be greater than 0.05g for the 4 
hours.
    (ii) Running loss enclosures. The enclosure background emissions 
(hydrocarbons plus methanol) shall not be greater than 0.2 grams for the 
4 hours.
    (b) Initial determination of enclosure internal volume. Prior to its 
introduction into service the enclosure internal volume shall be 
determined by the following procedure:
    (1) Carefully measure the internal length, width and height of the 
enclosure, accounting for irregularities (such as braces) and calculate 
the internal volume. For variable-volume enclosures, latch the enclosure 
to a fixed volume when the enclosure is held at a constant temperature; 
this nominal volume shall be repeatable within 0.5 
percent of the reported value.
    (2)-(3) [Reserved]
    (c) Hydrocarbon and methanol (organic gas) retention check and 
calibration. The hydrocarbon and methanol (if the enclosure is used for 
methanol-fueled vehicles) retention check provides a check upon the 
calculated volume and also measures the leak rate. The enclosure leak 
rate shall be determined prior to its introduction into service, 
following any modifications or repairs to the enclosure that may affect 
the integrity of the enclosure, and at least monthly thereafter. The 
methanol retention check must be performed only upon initial 
installation and after major maintenance, consistent with good 
engineering judgment. If six consecutive monthly retention checks are 
successfully completed without corrective action, the enclosure leak 
rate may be determined quarterly thereafter as long as no corrective 
action is required.
    (1) An enclosure to be used for the diurnal emission test (see Sec.
86.133-96)

[[Page 661]]

shall be calibrated according to the following procedure. Calibration 
for hydrocarbon and methanol may be conducted simultaneously or in 
sequential test runs.
    (i) Zero and span (calibrate if required) the hydrocarbon analyzer.
    (ii) Purge the enclosure until a stable background hydrocarbon 
reading is obtained.
    (iii) Turn on the mixing blowers (if not already on).
    (iv) [Reserved]
    (v) Turn on the ambient temperature control system (if not already 
on) and adjust it for an initial temperature of 96 [deg]F (36 [deg]C). 
On variable-volume enclosures, latch the enclosure to the appropriate 
volume position for the set temperature. On fixed-volume enclosures 
close the outlet and inlet flow streams.
    (vi) When the enclosure stabilizes at 963 
[deg]F (362 [deg]C), seal the enclosure and 
measure background hydrocarbon concentration, background methanol, 
temperature, and barometric pressure. These are the initial readings 
CHCi, CCH3OHi, Ti, and 
PBi for the enclosure calibration.
    (vii) Inject into the enclosure 0.5 to 1.0 grams of pure methanol at 
a recommended temperature of at least 150 [deg]F (65 [deg]C) and/or 0.5 
to 1.0 grams of pure propane at lab ambient temperature. The injected 
quantity may be measured by volume flow or by mass measurement. The 
method used to measure the quantity of methanol and propane must have an 
accuracy of 0.5 percent of the measured value 
(less accurate methods may be used with the advance approval of the 
Administrator).
    (viii) After a minimum of 5 minutes of mixing, analyze the enclosure 
atmosphere for hydrocarbon and methanol content, also record temperature 
and pressure. These measurements are the final readings for the 
enclosure calibration as well as the initial readings for the retention 
check.
    (ix) To verify the enclosure calibration, calculate the mass of 
propane and the mass of methanol using the measurements taken in 
paragraphs (c)(1)(vi) and (viii) of this section. See paragraph (d) of 
this section. This quantity must be within 2 
percent of that measured in paragraph (c)(1)(vii) of this section for 
propane and 5 percent for methanol. Evaluate long-
term trends using good engineering judgment to minimize measurement 
bias. Keep records to document such evaluations and make them available 
to EPA upon request.
    (x) For variable-volume enclosures, unlatch the enclosure from the 
nominal volume configuration. For fixed-volume enclosures, open the 
outlet and inlet flow streams.
    (xi) Start cycling the ambient temperature from 96 [deg]F to 72 
[deg]F and back to 96 [deg]F over a 24-hour period, according to the 
profile specified in Sec.86.133-96 and appendix II of this part, 
within 15 minutes of sealing the enclosure.
    (xii) At the completion of the 24-hour cycling period, analyze the 
enclosure atmosphere for hydrocarbon and methanol content; determine the 
net withdrawn methanol (in the case of diurnal emission testing with 
fixed volume enclosures); record temperature and barometric pressure. 
These are the final readings for the hydrocarbon and methanol retention 
check. The final hydrocarbon and methanol mass, calculated in paragraph 
(d) of this section, shall be within three percent of that determined in 
paragraph (c)(1)(viii) of this section. (For 1991-1995 calendar years, 
the difference may exceed 3 percent for methanol, 
provided it does not exceed 6 percent.)
    (2) An enclosure to be used for the running loss test (see Sec.
86.134-96) shall meet the calibration and retention requirements of 
Sec.86.117-90(c).
    (3) Enclosures calibrated according to the procedures specified in 
either paragraph (c)(1) or (c)(2) of this section may be used for hot 
soak testing (see Sec.86.138).
    (d) Calculations. (1) The calculation of net methanol and 
hydrocarbon mass change is used to determine enclosure background and 
leak rate. It is also used to check the enclosure volume measurements. 
The methanol mass change is calculated from the initial and final 
methanol samples, the net withdrawn methanol (in the case of diurnal 
emission testing with fixed-volume enclosures), and initial and final 
temperature and pressure according to the following equation:

    (e) Calibration of equipment for point-source testing of running 
losses. For the point-source method, the running loss fuel vapor 
sampling system shall be calibrated as a CVS system, as specified in 
Sec.86.119, with the additional specification that the vapor sampling 
system verification be conducted as follows:
    (1) The following ``gravimetric'' technique can be used to verify 
that the vapor sampling system and analytical instruments can accurately 
measure a mass of gas that has been injected into the system. If the 
vapor sampling system will be used only in the testing of petroleum-
fueled engines, the system verification may be performed using propane. 
If the vapor sampling system will be used with methanol-fueled vehicles 
as well as petroleum-fueled vehicles, the system verification 
performance check must include a methanol check in addition to the 
propane check. (Verification can also be accomplished by constant flow 
metering using critical flow orifice devices.)
    (i) Obtain a small cylinder that has been charged with pure propane 
gas. Obtain another small cylinder that has been charged with pure 
methanol if the system will be used for methanol-fueled vehicle testing. 
Since this cylinder will be heated to 150-155 [deg]F, care must be taken 
to ensure that the liquid volume of methanol placed in the cylinder does 
not exceed approximately one-half of the total volume of the cylinder.
    (ii) Determine a reference cylinder weight to the nearest 0.01 
grams.
    (iii) Operate the vapor sampling system in the normal manner and 
release a known quantity of pure propane into the most frequently used 
fuel vapor collector during the sampling period (approximately 5 
minutes).
    (iv) Continue to operate the vapor sampling system in the normal 
manner and release a known quantity of pure methanol into the system 
during the sampling period (approximately 5 minutes).
    (v) The calculations of Sec.86.144 are performed in the normal 
way, except in the case of propane. The density of propane (17.30 g/
ft\3\/carbon atom (0.6109 kg/m\3\/carbon atom)) is used in place of the 
density of exhaust hydrocarbons. In the case of methanol, the density of 
37.71 g/ft\3\ (1.332 kg/m\3\) is used.
    (vi) The gravimetric mass is subtracted from the vapor sampling 
system measured mass and then divided by the gravimetric mass to 
determine the percent accuracy of the system.
    (vii) The cause for any discrepancy greater than 2 percent must be found and corrected.
    (2) This procedure shall be conducted in the point-source running 
loss test environment with the collector installed in a vehicle in the 
normal test configuration. The fuel of the test vehicle shall either be 
diesel, or it shall be kept under 100 [deg]F (38 [deg]C). Two to six 
grams of pure propane and two to six grams of pure methanol shall be 
injected into the collector while the vehicle is operated over one Urban 
Dynamometer Driving Schedule (UDDS), as described in Sec.86.115 and 
appendix I of this part. The propane and methanol injections shall be 
conducted at the ambient temperature of 955 [deg]F 
(353 [deg]C).

Sec.86.119-90  CVS calibration.

    The CVS is calibrated using an accurate flowmeter and restrictor 
valve. Measurements of various parameters are made and related to flow 
through the unit. Procedures used by EPA for both PDP and CFV are 
outlined below. Other procedures yielding equivalent results may be used 
if approved in advance by the Administrator. After the calibration curve 
has been obtained, verification of the entire system can be performed by 
injecting a known mass of gas into the system and comparing the mass 
indicated by the system to the true mass injected. An indicated error 
does not necessarily mean that the calibration is wrong, since other 
factors can influence the accuracy of the system, e.g., analyzer 
calibration. A verification procedure is found in paragraph (c) of this 
section.
    (a) PDP calibrations. (1) The following calibration procedure 
outlines the equipment, the test configuration, and the various 
parameters which must be measured to establish the flow rate of the CVS 
pump. All the parameters related to the pump are simultaneously measured 
with the parameters related to a flowmeter which is connected in series 
with the pump. The calculated flow rate ft\3\/min (at pump inlet 
absolute pressure and temperature) can then be plotted versus a 
correlation function which is the value on a specific combination of 
pump parameters. The linear equation which relates the pump flow and the 
correlation function is then determined. In the event that a CVS has a 
multiple speed drive, a calibration for each range used must be 
performed.
    (2) This calibration procedure is based on the measurement of the 
absolute values of the pump and flowmeter parameters that relate the 
flow rate at each point. Three conditions must be maintained to assure 
the accuracy and integrity of the calibration curve. First, the pump 
pressures should be measured at taps on the pump rather than at the 
external piping on the pump inlet and outlet. Pressure taps that are 
mounted at the top center and bottom center of the pump drive headplate 
are exposed to the actual pump cavity pressures, and therefore reflect 
the absolute pressure differentials. Secondly, temperature stability 
must be maintained during the calibration. The laminar flowmeter is 
sensitive to inlet temperature oscillations which cause the data points 
to be scattered. Gradual changes (2 [deg]F (1.1 
[deg]C)) in temperature are acceptable as long as they occur over a 
period of several minutes. Finally, all connections between the 
flowmeter and the CVS pump must be absolutely void of any leakage.
    (3) During an exhaust emission test the measurement of these same 
pump parameters enables the user to calculate the flow rate from the 
calibration equation.
    (4) Connect a system as shown in Figure B90-8. Although particular 
types of equipment are shown, other configurations that yield equivalent 
results may be used if approved in advance by the Administrator. For the 
system indicated, the following data with given accuracy are required:

that will yield a minimum of six data points for the total calibration. 
Allow the system to stabilize for 3 minutes and repeat the data 
acquisition.
    (7) Data analysis:
    (i) The air flow rate, Qs, at each test point is 
calculated in standard cubic feet per minute from the flowmeter data 
using the manufacturer's prescribed method.
    (ii) The air flow rate is then converted to pump flow, 
Vo, in cubic feet per revolution at absolute pump inlet 
temperature and pressure:


[[Page 667]]


Vo = (Qs/n) x (Tp/528) x (29.92/
Pp)

Where:

(A) Vo = Pump flow ft\3\/rev (m\3\/rev) at Tp, 
          Pp.
(B) Qs = Meter air flow rate in standard cubic feet per 
          minute, standard conditions are 68 [deg]F, 29.92 in. Hg (20 
          [deg]C, 101.3 kPa).
(C) n = Pump speed in revolutions per minute.
(D)(1) Tp = Pump inlet temperature, [deg]R([deg]K) = PTI + 
          460.

(2) For SI units, Tp = PTI + 273.

(E)(l) Pp = Absolute pump inlet pressure, in. Hg. (kPa) = 
PB - PPI (SP.GR./13.57).
(2) For SI units, Pp = PB - PPI.

Where:

(F) PB = barometric pressure, in. Hg. (kPa).
(G) PPI = Pump inlet depression, in. fluid (kPa).
(H) SP.GR. = Specific gravity of manometer fluid relative to water.

    (iii) The correlation function at each test point is then calculated 
from the calibration data:
[GRAPHIC] [TIFF OMITTED] TR06OC93.021

Where:

(A) Xo = correlation function.
(B) [Delta] Pp = the pressure differential from pump inlet to 
          pump outlet, in. Hg (kPa) = Pe - Pp.

(C)(1) Pe = Absolute pump outlet pressure, in Hg, (kPa) = 
PB + PPO (SP.GR./13.57).

(2) For SI units, Pe = PB + PPO.

Where:

(D) PPO = Pressure head at pump outlet, in. fluid (kPa).
(iv) A linear least squares fit is performed to generate the calibration 
          equations which have the forms:
Vo = Do - M(Xo)
n = A - B([Delta] Pp)
Do, M, A, and B are the slope-intercept constants describing 
          lines.

    (8) A CVS system that has multiple speeds should be calibrated on 
each speed used. The calibration curves generated for the ranges will be 
approximately parallel and the intercept values, Do, will 
increase as the pump flow range decreases.
    (9) If the calibration has been performed carefully, the calculated 
values from the equation will be within 0.50 
percent of the measured value of Vo. Values of M will vary 
from one pump to another, but values of Do for pumps of the 
same make, model, and range should agree within 3 
percent of each other. Particulate influx from use will cause the pump 
slip to decrease as reflected by lower values for M. Calibrations should 
be performed at pump start-up and after major maintenance to assure the 
stability of the pump slip rate. Analysis of mass injection data will 
also reflect pump slip stability.
    (b) CFV calibration. (1) Calibration of the CFV is based upon the 
flow equation for a critical venturi. Gas flow is a function of inlet 
pressure and temperature:
[GRAPHIC] [TIFF OMITTED] TR06OC93.022


Where:

(i) Qs = Flow.
(ii) Kv = Calibration coefficient.
(iii) P = Absolute pressure.
(iv) T = Absolute temperature.


The calibration procedure described below establishes the value of the 
calibration coefficient at measured values of pressure, temperature and 
air flow.
    (2) The manufacturer's recommended procedure shall be followed for 
calibrating electronic portions of the CFV.
    (3) Measurements necessary for flow calibration are as follows:

Any leaks between the flow measuring device and the critical flow 
venturi will seriously affect the accuracy of the calibration.

    (5) Set the variable flow restrictor to the open position, start the 
blower, and allow the system to stabilize. Record data from all 
instruments.
    (6) Vary the flow restrictor and make at least 8 readings across the 
critical flow range of the venturi.
    (7) Data analysis: The data recorded during the calibration are to 
be used in the following calculations:
    (i) The air flow rate, Qs, at each test point is 
calculated in standard cubic feet per minute from the flow meter data 
using the manufacturer's prescribed method.
    (ii) Calculate values of the calibration coefficient for each test 
point:

[[Page 670]]

[GRAPHIC] [TIFF OMITTED] TR06OC93.023


Where:

(A) Qs = Flow rate in standard cubic feet per minute, 
standard conditions are 68 [deg]F 29.92 in. Hg (20 [deg]C, 101.3 kPa).
(B) Tv = Temperature at venturi inlet, [deg]R([deg]K).
(C)(1) Pv = Pressure at venturi inlet, mm Hg (kPa) = 
PB - PPI (SP.GR./13.57).
(2) For SI units, Pv = PB - PPI.

Where:

(D) PPI = Venturi inlet pressure depression, in. fluid (kPa).
(E) SP.GR. = Specific gravity of manometer fluid, relative to water.

    (iii) Plot Kv as a function of venturi inlet pressure. 
For sonic flow Kv will have a relatively constant value. As 
pressure decreases (vacuum increases), the venturi becomes unchoked and 
Kv decreases. See Figure B90-10.

[[Page 671]]

[GRAPHIC] [TIFF OMITTED] TR06OC93.200

    (iv) For a minimum of 8 points in the critical region calculate an 
average Kv and the standard deviation.
    (v) If the standard deviation exceeds 0.3 percent of the average 
Kv take corrective action.
    (8) Calculation of a parameter for monitoring sonic flow in the CFV 
during exhaust emissions tests:
    (i) Option 1. (A) CFV pressure ratio. Based upon the calibration 
data selected to meet the criteria for paragraphs (d)(7) (iv) and (v) of 
this section, in which Kv is constant, select the data values 
associated with the calibration point with the lowest absolute venturi

inlet pressure. With this set of calibration data, calculated the 
following CFV pressure ratio limit, Prratio-lim:
[GRAPHIC] [TIFF OMITTED] TR18FE00.022

Where:

Pin-cal = Venturi inlet pressure (PPI in absolute pressure 
          units), and
Pout-cal = Venturi outlet pressure (PPO in absolute pressure 
          units), measured at the exit of the venturi diffuser outlet.

    (B) The venturi pressure ratio (Prratio-i) during all 
emissions tests must be less than, or equal to, the calibration pressure 
ratio limit (Prratio-lim) derived from the CFV calibration 
data, such that:
[GRAPHIC] [TIFF OMITTED] TR18FE00.023

Where:

Pin-i and Pout-i are the venturi inlet and outlet 
          pressures, in absolute pressure units, at each i-th interval 
          during the emissions test.

    (ii) Option 2. Other methods: With prior Administrator approval, any 
other method may be used that assure that the venturi operates at sonic 
conditions during emissions tests, provided the method is based upon 
sound engineering principles.
    (c) CVS System Verification. The following ``gravimetric'' technique 
can be used to verify that the CVS and analytical instruments can 
accurately measure a mass of gas that has been injected into the system. 
If the CVS and analytical system will be used only in the testing of 
petroleum-fueled engines, the system verification may be performed using 
either propane or carbon monoxide. If the CVS and analytical system will 
be used with methanol-fueled vehicles as well as petroleum-fueled 
vehicles, system verification performance check must include a methanol 
check in addition to either the propane or carbon monoxide check. 
(Verification can also be accomplished by constant flow metering using 
critical flow orifice devices.)
    (1) Obtain a small cylinder that has been charged with pure propane 
or carbon monoxide gas (CAUTION--carbon monoxide is poisonous).
    (2) Determine a reference cylinder weight to the nearest 0.01 grams.
    (3) Operate the CVS in the normal manner and release a quantity of 
pure propane or carbon monoxide into the system during the sampling 
period (approximately 5 minutes).
    (4) Following completion of step (3) in this paragraph (c) (if 
methanol injection is required), continue to operate the CVS in the 
normal manner and release a known quantity of pure methanol (in gaseous 
form) into the system during the sampling period (approximately five 
minutes). This step does not need to be performed with each 
verification, provided that it is performed at least twice annually.
    (5) The calculations of Sec.86.144 are performed in the normal 
way, except in the case of propane. The density of propane (17.30 g/
ft\3\/carbon atom (0.6109 kg/m\3\/carbon atom)) is used in place of the 
density of exhaust hydrocarbons. In the case of carbon monoxide, the 
density of 32.97 g/ft\3\ (1.164 kg/m\3\) is used. In the case of 
methanol, the density of 37.71 g/ft\3\ (1.332 kg/m\3\) is used.
    (6) The gravimetric mass is subtracted from the CVS measured mass 
and then divided by the gravimetric mass to determine the percent 
accuracy of the system.
    (7) The cause for any discrepancy greater than 2 percent must be found and corrected. (For 1991-1995 
calendar years, discrepancies greater than 2 
percent are allowed for the methanol test, provided that they do not 
exceed 8 percent for 1991 testing or 6 percent for 1992-1995 testing.)

Sec.86.120-94  Gas meter or flow instrumentation calibration;
particulate, methanol and formaldehyde measurement.

    (a) Sampling for particulate, methanol and formaldehyde emissions 
requires the use of gas meters or flow instrumentation to determine flow 
through the particulate filters, methanol impingers and formaldehyde 
impingers. These instruments shall receive initial and periodic 
calibrations as follows:

[[Page 673]]

    (1)(i) Install a calibration device in series with the instrument. A 
critical flow orifice, a bellmouth nozzle, a laminar flow element or an 
NBS traceable flow calibration device is required as the standard 
device.
    (ii) The flow system should be checked for leaks between the 
calibration and sampling meters, including any pumps that may be part of 
the system, using good engineering practice.
    (2) Flow air through the calibration system at the sample flow rate 
used for particulate, methanol, and formaldehyde testing and at the 
backpressure which occurs during the test.
    (3) When the temperature and pressure in the system have stabilized, 
measure the indicated gas volume over a time period of at least five 
minutes or until a gas volume of at least 1 
percent accuracy can be determined by the standard device. Record the 
stabilized air temperature and pressure upstream of the instrument and 
as required for the standard device.
    (4) Calculate air flow at standard conditions as measured by both 
the standard device and the instrument(s). (Standard conditions are 
defined as 68 [deg]F (20 [deg]C) and 29.92 in Hg (101.3 kPa).)
    (5) Repeat the procedures of paragraphs (a)(2) through (4) of this 
section using at least two flow rates which bracket the typical 
operating range.
    (6) If the air flow at standard conditions measured by the 
instrument differs by 1.0 percent of the maximum 
operating range or 2.0 percent of the point 
(whichever is smaller), then a correction shall be made by either of the 
following two methods:
    (i) Mechanically adjust the instrument so that it agrees with the 
calibration measurement at the specified flow rates using the criteria 
of paragraph (a)(6) of this section; or
    (ii) Develop a continuous best fit calibration curve for the 
instrument (as a function of the calibration device flow measurement) 
from the calibration points to determine corrected flow. The points on 
the calibration curve relative to the calibration device measurements 
must be within 1.0 percent of the maximum 
operating range of 2.0 percent of the point 
(whichever is smaller).
    (b) Other systems. A bell prover may be used to calibrate the 
instrument if the procedure outlined in ANSI B109.1-1973 is used. Prior 
approval by the Administrator is not required to use the bell prover.

[60 FR 34344, June 30, 1995]



Sec.86.121-90  Hydrocarbon analyzer calibration.

    The hydrocarbon analyzers shall receive the following initial and 
periodic calibration. The HFID used with petroleum-fueled diesel 
vehicles shall be operated at a temperature of 375 [deg]F10 [deg]F (191 [deg]6 [deg]C). The 
HFID used with methanol-fueled vehicles shall be operated at 235 
[deg]15 [deg]F (1138 
[deg]C).
    (a) Initial and periodic optimization of detector response. Prior to 
its introduction into service and at least annually thereafter, the FID 
and HFID hydrocarbon analyzers shall be adjusted for optimum hydrocarbon 
response. Alternate methods yielding equivalent results may be used, if 
approved in advance by the Administrator.
    (1) Follow the manufacturer's instructions or good engineering 
practice for instrument startup and basic operating adjustment using the 
appropriate FID fuel and zero-grade air.
    (2) Optimize on the most common operating range. Introduce into the 
analyzer a propane (methane as appropriate) in air mixture (methanol in 
air mixture for methanol-fueled vehicles when optional methanol 
calibrated HFID procedure is used during the 1994 model year) with a 
propane (or methane or methanol as appropriate) concentration equal to 
approximately 90 percent of the most common operating range.
    (3) One of the following is required for FID or HFID optimization:
    (i) For all FIDs and HFIDs, the procedures specified by the 
applicable FID or HFID manufacturer.
    (ii) For Beckman 400 FIDs only, implementation of the 
recommendations outlined in Society of Automotive Engineers (SAE) paper 
No. 770141, ``Optimization of Flame Ionization Detector for 
Determination of Hydrocarbons in Diluted Automobile Exhaust''; author, 
Glenn D. Reschke.
    (iii) For HFIDs only, the following peaking procedure. (A) With the 
fuel

[[Page 674]]

and air flow rates set in the manufacturer's recommendations, determine 
the analyzer response from the difference between the span-gas response 
and the zero gas response. Incrementally adjust the fuel flow above and 
below the manufacturer's specification. Record the span and zero 
response at these fuel flows. A plot of the difference between the span 
and zero response versus the fuel flow will be similar to the one shown 
in Fig. B87-11. Adjust the fuel-flow rate to the highest setting that 
produces the maximum analyzer response.
    (B) To determine the optimum air flow, use the fuel flow setting 
determined in paragraph (a)(3)(iii)(A) of this section and vary air 
flow.
    (iv) Alternative procedures may be used if approved in advance by 
the Administrator.
    (4) To determine the optimum air flow, use the FID fuel flow setting 
determined above and vary air flow.
    (5) After the optimum flow rates have been determined, record them 
for future reference.
    (b) Initial and periodic calibration. Prior to its introduction into 
service and monthly thereafter the FID or HFID hydrocarbon analyzers 
shall be calibrated on all normally used instrument ranges, and, if 
testing methanol vehicles under the procedure described in Sec.86.107-
90(a)(2)(ii) or Sec.86.110-90(a)(4), the methanol response factor 
shall be determined (paragraph (c) of this section). Use the same flow 
rate as when analyzing sample.
    (1) Adjust analyzer to optimize performance.
    (2) Zero the hydrocarbon analyzer with zero-grade air.
    (3) Calibrate on each normally used operating range with propane in 
air calibration gases (either methanol or methane in air as appropriate) 
having nominal concentrations of 15, 30, 45, 60, 75 and 90 percent of 
that range. For each range calibrated, if the deviation from a least 
squares best-fit straight line is two percent or less of the value at 
each data point, concentration values may be calculated by use of a 
single calibration factor for that range. If the deviation exceeds two 
percent at any point, the best-fit non-linear equation which represents 
the data to within two percent of each test point shall be used to 
determine concentration.
    (c) FID response factor to methanol. When the FID analyzer is to be 
used for the analysis of hydrocarbon samples containing methanol, the 
methanol response factor of the analyzer shall be established. The 
methanol response factor shall be determined at several concentrations 
in the range of concentrations in the exhaust sample, using either bag 
samples or gas bottles meeting the requirements of Sec.86.114.
    (1) The bag sample of methanol for analysis in the FID, if used, 
shall be prepared using the apparatus shown in Figure B90-11. A known 
volume of methanol is injected, using a microliter syringe, into the 
heated mixing zone (250 [deg]F (121 [deg]C)) of the apparatus. The 
methanol is vaporized and swept into the sample bag with a known volume 
of zero grade air measured by a gas flow meter meeting the performance 
requirements of Sec.86.120.

methane response factor of the analyzer must be established. To 
determine the total hydrocarbon FID response to methane, known methane 
in air concentrations traceable to the National Institute of Standards 
and Technology (NIST) must be analyzed by the FID. Several methane 
concentrations must be analyzed by the FID in the range of 
concentrations in the exhaust sample. The total hydrocarbon FID response 
to methane is calculated as follows:

Sec.86.122-78  Carbon monoxide analyzer calibration.

    The NDIR carbon monoxide analyzer shall receive the following 
initial and periodic calibrations:
    (a) Initial and periodic interference check. Prior to its 
introduction into service and annually thereafter the NDIR carbon 
monoxide analyzer shall be checked for response to water vapor and 
CO2:
    (1) Follow the manufacturer's instructions for instrument startup 
and operation. Adjust the analyzer to optimize performance on the most 
sensitive range to be used.
    (2) Zero the carbon monoxide analyzer with either zero-grade air or 
zero-grade nitrogen.
    (3) Bubble a mixture of 3 percent CO2 in N2 
through water at room temperature and record analyzer response.
    (4) An analyzer response of more than 1 percent of full scale for 
ranges above 300 ppm full scale or of more than 3 ppm on ranges below 
300 ppm full scale will require corrective action. (Use of conditioning 
columns is one form of corrective action which may be taken.)
    (b) Initial and periodic calibration. Prior to its introduction into 
service and monthly thereafter the NDIR carbon monoxide analyzer shall 
be calibrated.
    (1) Adjust the analyzer to optimize performance.
    (2) Zero the carbon monoxide analyzer with either zero-grade air or 
zero-grade nitrogen.
    (3) Calibrate on each normally used operating range with carbon 
monoxide in N2 calibration gases having nominal 
concentrations of 15, 30, 45, 60, 75, and 90 percent of that range. 
Additional calibration points may be generated. For each range 
calibrated, if the deviation from a least-squares best-fit straight line 
is 2 percent or less of the value at each data point, concentration 
values may be calculated by use of a single calibration factor for that 
range. If the deviation exceeds 2 percent at any point, the best-fit 
non-linear equation which represents the data to within 2 percent of 
each test point shall be used to determine concentration.



Sec.86.123-78  Oxides of nitrogen analyzer calibration.

    The chemiluminescent oxides of nitrogen analyzer shall receive the 
following initial and periodic calibration.
    (a) Prior to introduction into service and at least monthly 
thereafter the chemiluminescent oxides of nitrogen analyzer must be 
checked for NO2 to NO converter efficiency. Figure B78-9

[[Page 677]]

is a reference for paragraphs (a) (1) through (11) of this section.
    (1) Follow the manufacturer's instructions for instrument startup 
and operation. Adjust the analyzer to optimize performance.
    (2) Zero the oxides of nitrogen analyzer with zero-grade air or 
zero-grade nitrogen.
    (3) Connect the outlet of the NOX generator to the sample 
inlet of the oxides of nitrogen analyzer which has been set to the most 
common operating range.
    (4) Introduce into the NOX generator analyzer-system an 
NO in nitrogen (N2) mixture with an NO concentration equal to 
approximately 80 percent of the most common operating range. The 
NO2 content of the gas mixture shall be less than 5 percent 
of the NO concentration.
    (5) With the oxides of nitrogen analyzer in the NO mode, record the 
concentration of NO indicated by the analyzer.

[[Page 678]]

[GRAPHIC] [TIFF OMITTED] TR06OC93.160

    (6) Turn on the NOX generator O2 (or air) 
supply and adjust the O2 (or air) flow rate so that the NO 
indicated by the analyzer is about 10 percent less than indicated in 
step (5). Record the concentration of NO in this NO + O2 
mixture.
    (7) Switch the NOX generator to the generation mode and 
adjust the generation rate so that the NO measured on the analyzer is 20 
percent of that measured in step (5). There must be at least 10 percent 
unreacted NO at this point. Record the concentration of residual NO.
    (8) Switch the oxides of nitrogen analyzer to the NOX 
mode and measure total NOX. Record this value.
    (9) Switch off the NOX generation but maintain gas flow 
through the system. The oxides of nitrogen analyzer will indicate the 
NOX in the NO + O2 mixture. Record this value.
    (10) Turn off the NOX generator O2 (or air) 
supply. The analyzer will now indicate the NOX in the 
original NO in N2

[[Page 679]]

mixture. This value should be no more than 5 percent above the value 
indicated in step (4).
    (11) Calculate the efficiency of the NOX converted by 
substituting the concentrations obtained into the following equation:

Percent Efficiency = [1 + (a - b)/(c - d)] x 100

where:
a = concentration obtained in step (8).
b = concentration obtained in step (9).
c = concentration obtained in step (6).
d = concentration obtained in step (7).


If converter efficiency is not greater than 90 percent corrective action 
will be required.
    (b) Initial and periodic calibration. Prior to its introduction into 
service and monthly thereafter the chemiluminescent oxides of nitrogen 
analyzer shall be calibrated on all normally used instrument ranges. Use 
the same flow rate as when analyzing samples. Proceed as follows:
    (1) Adjust analyzer to optimize performance.
    (2) Zero the oxides of nitrogen analyzer with zero-grade air or 
zero-grade nitrogen.
    (3) Calibrate on each normally used operating range with NO in N2 
calibration gases having nominal concentrations of 15, 30, 45, 60, 75, 
and 90 percent of that range. For each range calibrated, if the 
deviation from a least-squares best-fit straight line is 2 percent or 
less of the value at each data point, concentration values may be 
calculated by use of a single calibration factor for that range. If the 
deviation exceeds 2 percent at any point, the best-fit non-linear 
equation which represents the data to within 2 percent of each test 
point shall be used to determine concentration.
    (c) When testing methanol-fueled vehicles, it may be necessary to 
clean the analyzer frequently to prevent interference with 
NOX measurements (see EPA/600/S3-88/040).

Sec.86.124-78  Carbon dioxide analyzer calibration.

    Prior to its introduction into service and monthly thereafter the 
NDIR carbon dioxide analyzer shall be calibrated:
    (a) Follow the manufacturer's instructions for instrument startup 
and operation. Adjust the analyzer to optimize performance.
    (b) Zero the carbon dioxide analyzer with either zero-grade air or 
zero-grade nitrogen.
    (c) Calibrate on each normally used operating range with carbon 
dioxide in N2 calibration gases with nominal concentrations 
of 15, 30, 45, 60, 75, and 90 percent of that range. Additional 
calibration points may be generated. For each range calibrated, if the 
deviation from a least-squares best-fit straight line is 2 percent or 
less of the value at each data point, concentration values may be 
calculated by use of a single calibration factor for that range. If the 
deviation exceeds 2 percent at any point, the best-fit non-linear 
equation which represents the data to within 2 percent of each test 
point shall be used to determine concentration.



Sec.86.125-94  Methane analyzer calibration.

    Prior to introduction into service and monthly thereafter, the 
methane analyzer shall be calibrated:
    (a) Follow the manufacturer's instructions for instrument startup 
and operation. Adjust the analyzer to optimize performance.
    (b) Zero the methane analyzer with zero-grade air.
    (c) Calibrate on each normally used operating range with 
CH4 in air with nominal concentrations of 15, 30, 45, 60, 75, 
and 90 percent of that range. Additional calibration points may be 
generated. For each range calibrated, if the deviation from a least-
squares best-fit straight line is 2 percent or less of the value at each 
data point, concentration values may be calculated by use of a single 
calibration factor for that range. If the deviation exceeds 2 percent at 
any point, the best-fit non-linear equation which represents the data to 
within 2 percent of each test

[[Page 680]]

point shall be used to determine concentration.

Sec.86.126-90  Calibration of other equipment.

    Other test equipment used for testing shall be calibrated as often 
as required by the manufacturer or as necessary according to good 
practice. Specific equipment requiring calibration are the gas 
chromatograph and flame ionization detector used in measuring methanol 
and the high pressure liquid chromatograph (HPLC) and ultraviolet 
detector for measuring formaldehyde.

Sec.86.127-00  Test procedures; overview.

    Applicability. The procedures described in this and subsequent 
sections are used to determine the conformity of vehicles with the 
standards set forth in subpart A or S of this part (as applicable) for 
light-duty vehicles and light-duty trucks. Except where noted, the 
procedures of paragraphs (a) through (b) of this section, Sec.86.127-
96 (c) and (d), and the contents of Sec. Sec.86.135-94, 86.136-90, 
86.137-96, 86.140-94, 86.142-90, and 86.144-94 are applicable for 
determining emission results for vehicle exhaust emission systems 
designed to comply with the FTP emission standards, or the FTP emission 
element required for determining compliance with composite SFTP 
standards. Paragraphs (f) and (g) of this section discuss the additional 
test elements of aggressive driving (US06) and air conditioning (SC03) 
that comprise the exhaust emission components of the SFTP. Section 
86.127-96(e) discusses fuel spitback emissions and paragraphs (h) and 
(i) of this section are applicable to all vehicle emission test 
procedures. Section 86.127-00 includes text that specifies requirements 
that differ from Sec.86.127-96. Where a paragraph in Sec.86.127-96 
is identical and applicable to Sec.86.127-00, this may be indicated by 
specifying the corresponding paragraph and the statement ``[Reserved]. 
For guidance see Sec.86.127-96.''
    (a) The overall test consists of prescribed sequences of fueling, 
parking, and operating test conditions. Vehicles are tested for any or 
all of the following emissions:
    (1) Gaseous exhaust THC, CO, NOX. CO2 (for 
petroleum-fueled and gaseous- fueled vehicles), plus CH3OH 
and HCHO for methanol-fueled vehicles, plus CH4 (for vehicles 
subject to the NMHC and NMHCE standards).
    (2) Particulates.
    (3) Evaporative HC (for gasoline-fueled, methanol-fueled and 
gaseous-fueled vehicles) and CH3OH (for methanol-fueled 
vehicles). The evaporative testing portion of the procedure occurs after 
the exhaust emission test; however, exhaust emissions need not be 
sampled to complete a test for evaporative emissions.
    (4) Fuel spitback (this test is not required for gaseous-fueled 
vehicles).
    (b) The FTP Otto-cycle exhaust emission test is designed to 
determine gaseous THC, CO, CO2, CH4, 
NOX, and particulate mass emissions from gasoline-fueled, 
methanol-fueled and gaseous-fueled Otto-cycle vehicles as well as 
methanol and formaldehyde from methanol-fueled Otto-cycle vehicles, 
while simulating an average trip in an urban area of 11 miles (18 
kilometers). The test consists of engine start-ups and vehicle operation 
on a chassis dynamometer through a specified driving schedule (see 
paragraph (a), EPA Urban Dynamometer Driving Schedule, of appendix I to 
this part). A proportional part of the diluted exhaust is collected 
continuously for subsequent analysis, using a constant volume (variable 
dilution) sampler or critical flow venturi sampler.
    (c)-(e) [Reserved]. For guidance see Sec.86.127-96.
    (f) The element of the SFTP for exhaust emissions related to 
aggressive driving (US06) is designed to determine gaseous THC, NMHC, 
CO, CO2, CH4, and NOX emissions from 
gasoline-fueled or diesel-fueled vehicles (see Sec.86.158-00 
Supplemental test procedures; overview, and Sec.86.159-00 Exhaust 
emission test procedures for US06 emissions). The test cycle simulates 
urban driving speeds and accelerations that are not represented by the 
FTP Urban Dynamometer Driving Schedule simulated trips discussed in 
paragraph (b) of this section. The test consists of vehicle operation on 
a chassis dynamometer

[[Page 681]]

through a specified driving cycle (see paragraph (g), US06 Dynamometer 
Driving Schedule, of appendix I to this part). A proportional part of 
the diluted exhaust is collected continuously for subsequent analysis, 
using a constant volume (variable dilution) sampler or critical flow 
venturi sampler.
    (g)(1) The element of the SFTP related to the increased exhaust 
emissions caused by air conditioning operation (SC03) is designed to 
determine gaseous THC, NMHC, CO, CO2, CH4, and 
NOX emissions from gasoline-fueled or diesel fueled vehicles 
related to air conditioning use (see Sec.86.158-00 Supplemental 
federal test procedures; overview and Sec.86.160-00 Exhaust emission 
test procedure for SC03 emissions). The test cycle simulates urban 
driving behavior with the air conditioner operating. The test consists 
of engine startups and vehicle operation on a chassis dynamometer 
through specified driving cycles (see paragraph (h), SC03 Dynamometer 
Driving Schedule, of appendix I to this part). A proportional part of 
the diluted exhaust is collected continuously for subsequent analysis, 
using a constant volume (variable dilution) sampler or critical flow 
venturi sampler. The testing sequence includes an approved 
preconditioning cycle, a 10 minute soak with the engine turned off, and 
the SC03 cycle with measured exhaust emissions.
    (2) The SC03 air conditioning test is conducted with the air 
conditioner operating at specified settings and the ambient test 
conditions of:
    (i) Air temperature of 95 [deg]F;
    (ii) 100 grains of water/pound of dry air (approximately 40 percent 
relative humidity);
    (iii) Simulated solar heat intensity of 850 W/m \2\ (see Sec.
86.161-00(d)); and
    (iv) air flow directed at the vehicle that will provide 
representative air conditioner system condenser cooling at all vehicle 
speeds (see Sec.86.161-00(e)).
    (3) Manufacturers have the option of simulating air conditioning 
operation during testing at other ambient test conditions provided they 
can demonstrate that the vehicle tail pipe exhaust emissions are 
representative of the emissions that would result from the SC03 cycle 
test procedure and the ambient conditions of paragraph (g)(2) of this 
section. The Administrator has approved two optional air conditioning 
test simulation procedures AC1 and AC2 (see Sec.86.162-00) for only 
the model years of 2000 through 2002. If a manufacturer desires to 
conduct simulation SC03 testing for model year 2003 and beyond, the 
simulation test procedure must be approved in advance by the 
Administrator (see Sec. Sec.86.162-00 and 86.163-00).
    (h) Except in cases of component malfunction or failure, all 
emission control systems installed on or incorporated in a new motor 
vehicle shall be functioning during all procedures in this subpart. 
Maintenance to correct component malfunction or failure shall be 
authorized in accordance with Sec.86.098-25 or Sec.86.1834-01 as 
applicable.
    (i) Background concentrations are measured for all species for which 
emissions measurements are made. For exhaust testing, this requires 
sampling and analysis of the dilution air. For evaporative testing, this 
requires measuring initial concentrations. (When testing methanol-fueled 
vehicles, manufacturers may choose not to measure background 
concentrations of methanol and/or formaldehyde, and then assume that the 
concentrations are zero during calculations.)

Sec.86.127-12  Test procedures; overview.

    Applicability. The procedures described in this subpart are used to 
determine the conformity of vehicles with the standards set forth in 
subpart A or S of this part (as applicable) for light-duty vehicles, 
light-duty trucks, and medium-duty passenger vehicles. Except where 
noted, the procedures of paragraphs (a) through (d) of this section, and 
the contents of Sec. Sec.86.135-00, 86.136-90, 86.137-96, 86.140-94, 
86.142-90, and 86.144-94 are applicable for determining emission results 
for vehicle exhaust emission systems designed to comply with the FTP 
emission standards, or the FTP emission element required for determining 
compliance with composite SFTP standards. Paragraph (e) of this section 
discusses fuel spitback emissions. Paragraphs (f) and

[[Page 682]]

(g) of this section discuss the additional test elements of aggressive 
driving (US06) and air conditioning (SC03) that comprise the exhaust 
emission components of the SFTP. Paragraphs (h) and (i) of this section 
are applicable to all vehicle emission test procedures.
    (a) The overall test consists of prescribed sequences of fueling, 
parking, and operating test conditions. Vehicles are tested for any or 
all of the following emissions, depending upon the specific test 
requirements and the vehicle fuel type:
    (1) Gaseous exhaust THC, NMHC, NMOG, CO, NOX, 
CO2, N2O, CH4, CH3OH, 
C2H5OH, C2H4O, and HCHO.
    (2) Particulates.
    (3) Evaporative HC (for gasoline-fueled, methanol-fueled and 
gaseous-fueled vehicles) and CH3OH (for methanol-fueled 
vehicles). The evaporative testing portion of the procedure occurs after 
the exhaust emission test; however, exhaust emissions need not be 
sampled to complete a test for evaporative emissions.
    (4) Fuel spitback (this test is not required for gaseous-fueled 
vehicles).
    (b) The FTP Otto-cycle exhaust emission test is designed to 
determine gaseous THC, NMHC, NMOG, CO, CO2, CH4, 
NOX, N2O, and particulate mass emissions from 
gasoline-fueled, methanol-fueled and gaseous-fueled Otto-cycle vehicles 
as well as methanol and formaldehyde from methanol-fueled Otto-cycle 
vehicles, as well as methanol, ethanol, acetaldehyde, and formaldehyde 
from ethanol-fueled vehicles, while simulating an average trip in an 
urban area of approximately 11 miles (approximately 18 kilometers). The 
test consists of engine start-ups and vehicle operation on a chassis 
dynamometer through a specified driving schedule (see paragraph (a) of 
appendix I to this part for the Urban Dynamometer Driving Schedule). A 
proportional part of the diluted exhaust is collected continuously for 
subsequent analysis, using a constant volume (variable dilution) sampler 
or critical flow venturi sampler.
    (c) The diesel-cycle exhaust emission test is designed to determine 
particulate and gaseous mass emissions during the test described in 
paragraph (b) of this section. For petroleum-fueled diesel-cycle 
vehicles, diluted exhaust is continuously analyzed for THC using a 
heated sample line and analyzer; the other gaseous emissions 
(CH4, CO, CO2, N2O, and NOX) 
are collected continuously for analysis as in paragraph (b) of this 
section. For methanol- and ethanol-fueled vehicles, THC, methanol, 
formaldehyde, CO, CO2, CH4, N2O, and 
NOX are collected continuously for analysis as in paragraph 
(b) of this section. Additionally, for ethanol-fueled vehicles, ethanol 
and acetaldehyde are collected continuously for analysis as in paragraph 
(b) of this section. THC, methanol, ethanol, acetaldehyde, and 
formaldehyde are collected using heated sample lines, and a heated FID 
is used for THC analyses. Simultaneous with the gaseous exhaust 
collection and analysis, particulates from a proportional part of the 
diluted exhaust are collected continuously on a filter. The mass of 
particulate is determined by the procedure described in Sec.86.139. 
This testing requires a dilution tunnel as well as the constant volume 
sampler.
    (d) The evaporative emission test (gasoline-fueled vehicles, 
methanol-fueled and gaseous-fueled vehicles) is designed to determine 
hydrocarbon and methanol evaporative emissions as a consequence of 
diurnal temperature fluctuation, urban driving and hot soaks following 
drives. It is associated with a series of events that a vehicle may 
experience and that may result in hydrocarbon and/or methanol vapor 
losses. The test procedure is designed to measure:
    (1) Diurnal emissions resulting from daily temperature changes (as 
well as relatively constant resting losses), measured by the enclosure 
technique (see Sec.86.133-96);
    (2) Running losses resulting from a simulated trip performed on a 
chassis dynamometer, measured by the enclosure or point-source technique 
(see Sec.86.134-96; this test is not required for gaseous-fueled 
vehicles); and
    (3) Hot soak emissions, which result when the vehicle is parked and 
the hot engine is turned off, measured by the enclosure technique (see 
Sec.86.138-96).
    (e) Fuel spitback emissions occur when a vehicle's fuel fill neck 
cannot

[[Page 683]]

accommodate dispensing rates. The vehicle test for spitback consists of 
a short drive followed immediately by a complete refueling event. This 
test is not required for gaseous-fueled vehicles.
    (f) The element of the SFTP for exhaust emissions related to 
aggressive driving (US06) is designed to determine gaseous THC, NMHC, 
CO, CO2, CH4, and NOX emissions from 
gasoline-fueled or diesel-fueled vehicles (see Sec.86.158-08 
Supplemental test procedures; overview, and Sec.86.159-08 Exhaust 
emission test procedures for US06 emissions). The test cycle simulates 
urban driving speeds and accelerations that are not represented by the 
FTP Urban Dynamometer Driving Schedule simulated trips discussed in 
paragraph (b) of this section. The test consists of vehicle operation on 
a chassis dynamometer through a specified driving cycle (see paragraph 
(g), US06 Dynamometer Driving Schedule, of appendix I to this part). A 
proportional part of the diluted exhaust is collected continuously for 
subsequent analysis, using a constant volume (variable dilution) sampler 
or critical flow venturi sampler.
    (g)(1) The element of the SFTP related to the increased exhaust 
emissions caused by air conditioning operation (SC03) is designed to 
determine gaseous THC, NMHC, CO, CO2, CH4, and 
NOX emissions from gasoline-fueled or diesel fueled vehicles 
related to air conditioning use (see Sec.86.158-08 Supplemental 
Federal test procedures; overview and Sec.86.160-00 Exhaust emission 
test procedure for SC03 emissions). The test cycle simulates urban 
driving behavior with the air conditioner operating. The test consists 
of engine startups and vehicle operation on a chassis dynamometer 
through specified driving cycles (see paragraph (h), SC03 Dynamometer 
Driving Schedule, of appendix I to this part). A proportional part of 
the diluted exhaust is collected continuously for subsequent analysis, 
using a constant volume (variable dilution) sampler or critical flow 
venturi sampler. The testing sequence includes an approved 
preconditioning cycle, a 10 minute soak with the engine turned off, and 
the SC03 cycle with measured exhaust emissions.
    (2) The SC03 air conditioning test is conducted with the air 
conditioner operating at specified settings and the ambient test 
conditions of:
    (i) Air temperature of 95 [deg]F;
    (ii) 100 grains of water/pound of dry air (approximately 40 percent 
relative humidity);
    (iii) Simulated solar heat intensity of 850 W/m\2\ (see Sec.
86.161-00(d)); and
    (iv) Air flow directed at the vehicle that will provide 
representative air conditioner system condenser cooling at all vehicle 
speeds (see Sec.86.161-00(e)).
    (3) Manufacturers have the option of simulating air conditioning 
operation during testing at other ambient test conditions provided they 
can demonstrate that the vehicle tail pipe exhaust emissions are 
representative of the emissions that would result from the SC03 cycle 
test procedure and the ambient conditions of paragraph (g)(2) of this 
section. The simulation test procedure must be approved in advance by 
the Administrator (see Sec. Sec.86.162-03 and 86.163-00).
    (h) Except in cases of component malfunction or failure, all 
emission control systems installed on or incorporated in a new motor 
vehicle shall be functioning during all procedures in this subpart. 
Maintenance to correct component malfunction or failure shall be 
authorized in accordance with Sec.86.007-25 or Sec.86.1834-01 as 
applicable.
    (i) Background concentrations are measured for all species for which 
emissions measurements are made. For exhaust testing, this requires 
sampling and analysis of the dilution air. For evaporative testing, this 
requires measuring initial concentrations. (When testing methanol-fueled 
vehicles, manufacturers may choose not to measure background

in gear with the clutch disengaged at least 5 seconds before the end of 
the idle mode.
    (d) The vehicle shall be driven with appropriate accelerator pedal 
movement necessary to achieve the speed versus time relationship 
prescribed by the driving schedule. Both smoothing of speed variations 
and excessive accelerator pedal perturbations are to be avoided.
    (e) Accelerations shall be driven smoothly following representative 
shift speeds and procedures. For manual transmissions, the operator 
shall release the accelerator pedal during each shift and accomplish the 
shift with minimum time. If the vehicle cannot accelerate at the 
specified rate, the vehicle shall be operated at maximum available power 
until the vehicle speed reaches the value prescribed for that time in 
the driving schedule.
    (f) The deceleration modes shall be run in gear using brakes or 
accelerator pedal as necessary to maintain the desired speed. Manual 
transmission vehicles shall have the clutch engaged and shall not change 
gears from the previous mode. For those modes which decelerate to zero, 
manual transmission clutches shall be depressed when the speed drops 
below 15 mph (24.1 km/h), when engine roughness is evident, or when 
engine stalling is imminent.
    (g)(1) In the case of test vehicles equipped with manual 
transmissions, the transmission shall be shifted in accordance with 
procedures which are representative of shift patterns that may 
reasonably be expected to be followed by vehicles in use, in terms of 
such variables as vehicle speed or percent rated engine speed. At the 
Administrator's discretion, a test vehicle may also be shifted according 
to the shift procedures recommended by the manufacturer to the ultimate 
purchaser, if such procedures differ from those which are reasonably 
expected to be followed by vehicles in use.
    (2) A manufacturer may recommend to the ultimate purchaser shift 
procedures other than those used in testing by the EPA, Provided that: 
All shift procedures (including multiple shift speeds) which the 
manufacturer proposes to supply to the ultimate purchaser are provided 
to the Administrator as part of the manufacturer's application for 
certification, or as an amendment to such application, under Sec.
86.079-32, Sec.86.079-33, Sec.86.082-34, or Sec.86.1844-01 as 
applicable.
    (h) Downshifting is allowed at the beginning of or during a power 
mode in accordance with the shift procedure determined in paragraph 
(g)(1) of this section.

Sec.86.129-00  Road load power, test weight, and inertia weight 
class determination.

    Applicability. Section 86.129-94 (a) applies to all vehicle testing. 
Section 86.129-80 (b) and (c) are applicable to vehicles from engine 
families which are not required to meet SFTP requirements, although a 
manufacturer may elect to use the requirements in paragraphs (e) and (f) 
of this section instead of Sec.86.129-80 (b) and (c) on any vehicle. 
Section 86.129-94(d) which discusses fuel temperature profile, is 
applicable to evaporative emission running loss

testing. Paragraphs (e) and (f) of this section are applicable to 
vehicles from engine families required to comply with SFTP requirements. 
Section 86.129-00 includes text that specifies requirements that differ 
from Sec.86.129-80 or Sec.86.129-94. Where a paragraph in Sec.
86.129-80 or Sec.86.129-94 is identical and applicable to Sec.
86.129-00, this may be indicated by specifying the corresponding 
paragraph and the statement ``[Reserved]. For guidance see Sec.86.129-
80.'' or ``[Reserved]. For guidance see Sec.86.129-94.''
    (a) [Reserved]. For guidance see Sec.86.129-94.
    (b)-(c) [Reserved]. For guidance see Sec.86.129-80.
    (d) [Reserved]. For guidance see Sec.86.129-94.
    (e)(1) For each test vehicle from an engine family required to 
comply with SFTP requirements, the manufacturer shall supply 
representative road load forces for the vehicle at speeds between 15 km/
hr (9.3 mph) and 115 km/hr (71.5 mph). The road load force shall 
represent vehicle operation on a smooth level road, during calm winds, 
with no precipitation, at an ambient temperature of 20 [deg]C (68 
[deg]F), and atmospheric pressure of 98.21 kPa. Road load force for low 
speed may be extrapolated. Manufacturers may, at their option, use road 
load forces meeting the objectives of paragraph (f) of this section for 
any vehicle.
    (2) The dynamometer's power absorption shall be set for each 
vehicle's emission test sequence such that the force imposed during 
dynamometer operation matches actual road load force at all speeds.
    (3) The 10 percent adjustment in road load power for air 
conditioning discussed in Sec.86.129-80(b)(3), is not applicable when 
road load forces are determined for dynamometer testing using paragraphs 
(e)(1) and (e)(2) of this section.
    (f)(1) Required test dynamometer inertia weight class selections for 
the test elements of FTP, US06, and SC03 are determined by the test 
vehicles test weight basis and corresponding equivalent weight as listed 
in the tabular information of Sec.86.129-94(a). With the exception of 
the fuel economy test weight information in footnote 4 to the table in 
Sec.86.129-94(a), none of the other footnotes to the tabular listing 
apply to emission tests utilizing an approved single roll dynamometer or 
equivalent dynamometer configuration. All light-duty vehicles and light 
light-duty trucks are to be tested at the inertia weight class 
corresponding to their equivalent test weight.
    (i) For light-duty vehicles and light light-duty trucks, test weight 
basis is loaded vehicle weight, which is the vehicle weight plus 300 
pounds.
    (ii) For heavy light-duty trucks, the definition of test weight 
basis varies depending on the SFTP test element being tested.
    (A) For the aggressive driving cycle (US06), the test weight basis 
is the vehicle curb weight plus 300 pounds.
    (B) For the FTP and the air conditioning (SC03) element of the SFTP, 
the test weight is the average of the curb weight plus GVWR.
    (C) Regardless of other requirements in this section relating to the 
testing of HLDTs, for Tier 2 HLDTs, the test weight basis for FTP and 
SFTP testing (both US06 and SC03), if applicable, is the vehicle curb 
weight plus 300 pounds. For MDPVs certified to standards in bin 11 in 
Tables S04-1 and 2 in Sec.86.1811-04, the test weight basis must be 
adjusted loaded vehicle weight (ALVW) as defined in this part.
    (2) Dynamic inertia load adjustments may be made to the test inertia 
weight during specific US06 acceleration events when wide open throttle 
operation is equal to or greater than eight (8) seconds (see Sec.
86.108-00). The dynamic inertia weight adjustment procedure must be 
approved in advance of conducting official US06 testing. The 
Administrator will perform confirmatory US06 testing using the same 
dynamometer inertia adjustment procedures as the manufacturer if:
    (i) The manufacturer submits a request to the Administrator; and
    (ii) The manufacturer provides the dynamometer hardware and/or 
software necessary for these adjustments to the Administrator.

Sec.86.129-80  Road load power, test weight, and inertia weight
class determination.

    (a) [Reserved]
    (b) Power absorption unit adjustment--light-duty trucks. (1) The 
power absorption unit shall be adjusted to reproduce road load power at 
50 mph true speed. The indicated road load power setting shall take into 
account the dynamometer friction. The relationship between road load 
(absorbed) power and indicated road load power for a particular 
dynamometer shall be determined by the procedure outlined in Sec.
86.118 or other suitable means.
    (2) The road load power listed in the table above shall be used or 
the vehicle manufacturer may determine the road load power by an 
alternate procedure requested by the manufacturer and approved in 
advance by the Administrator.
    (3) Where it is expected that more than 33 percent of a car line 
within an engine-system combination will be equipped with air 
conditioning per Sec.86.080-24(g)(2), the road load power listed above 
or as determined in paragraph (b)(2) of this section shall be increased 
by 10 percent, up to a maximum increase of 1.4 horsepower, for testing 
all test vehicies representing that car line within that engine-system 
combination if those vehicles are intended to be offered with air 
conditioning in production. The above increase for air conditioning 
shall be added prior to rounding off as instructed by notes 2 and 3 of 
the table.
    (c) Power absorption unit adjustment--light-duty vehicles. (1) The 
power absorption unit shall be adjusted to reproduce road load power at 
50 mph true speed. The dynamometer power absorption shall take into 
account the dynamometer friction, as discussed in Sec.86.118.
    (2) The dynamometer road load setting is determined from the 
equivalent test weight, the reference frontal area, the body shape, the 
vehicle protuberances, and the tire type by the following equations.
    (i) For light-duty vehicles to be tested on a twin roll dynamometer.

Hp = aA + P + tW

where:

Hp = the dynamometer power absorber setting at 50 mph (horsepower).
A = the vehicle reference frontal area (ft\2\). The vehicle reference 
          frontal area is defined as the area of the orthogonal 
          projection of the vehicle; including tires and suspension 
          components, but excluding vehicle protuberances, onto a plane 
          perpendicular to both the longitudinal plane of the vehicle 
          and the surface upon which the vehicle is positioned. 
          Measurements of this area shall be computed to the nearest 
          tenth of a square foot using a method approved in advance by 
          the Administrator.
P = the protuberance power correction factor from table 1 of this 
          paragraph (horsepower).
W = vehicle equivalent test weight (lbs) from the table in paragraph 
          (a).
a = 0.43 for fastback-shaped vehicles; = 0.50 for all other light duty 
          vehicles.
t = 0.0 for vehicles equipped with radial ply tires; = 3 x 
          10- 4 for all other vehicles.

    A vehicle is considered to have a fastback shape if the rearward 
projection of that portion of the rear surface (Ab) which 
slopes at an angle of less than 20 degrees from the horizontal is at 
least 25 percent as large as the vehicle reference frontal area. In 
addition, this surface must be smooth, continuous, and free from any 
local transitions greater than four degrees. An example of a fastback 
shape is presented in Figure 1.

------------------------------------------------------------------------

    The protuberance frontal area, Ap, is defined in a manner analogous 
to the definition of the vehicle reference frontal area, i.e., the total 
area of the orthogonal projections of the vehicle mirrors, hood 
ornaments, roof racks, and other protuberance onto a plane(s) 
perpendicular to both the longitudinal plane of the vehicle and the 
surface upon which the vehicle is positioned. A protuberance is defined 
as any fixture attached to the vehicle protruding more than 1 inch from 
the vehicle surface and having a projected area greater than 0.01 ft\2\ 
with the area calculated by a method approved in advance by the 
Administrator. Included in the total protuberance frontal area shall be 
all fixtures which occur as standard equipment. The area of any optional 
equipment shall also be included if it is expected that more than 33 
percent of the car line sold will be equipped with this option.

    (ii) The dynamometer power absorber setting for light-duty vehicles 
shall be rounded to the nearest 0.1 horsepower.
    (iii) For light-duty vehicles to be tested on a single, large roll 
dynamometer.

Hp = aA + P + (5.0 x 10 -4 + 0.33t)W

All symbols in the above equation are defined in paragraph (c)(2)(i) of 
          this section. The rounding criteria of paragraph (c)(2)(i) 
          also apply to this paragraph.

    (3) The road load power calculated above shall be used or the 
vehicle manufacturer may determine the road load power by an alternate 
procedure requested by the manufacturer and approved in advance by the 
Administrator.
    (4) Where it is expected that more than 33 percent of a car line 
within an engine-system combination will be equipped with air 
conditioning, per Sec.86.080-24(g)(2), the road load power as 
determined in paragraph (c) (2) or (3) of this section shall be 
increased by 10 percent up to a maximum increment of 1.4 horsepower, for 
testing all test vehicles of that car line within that engine-system 
combination if those vehicles are intended to be offered with air 
conditioning in production. This power increment shall be added to the 
indicated dynamometer power absorption setting prior to rounding off 
this value.

\1\ For all light-duty trucks except vans, and for heavy-duty vehicles
  optionally certified as light-duty trucks, and for complete heavy-duty
  vehicles, the road load power (horsepower) at 50 mi/h shall be 0.58
  times B (defined in footnote 3 of this table) rounded to the nearest
  \1/2\ horsepower.
\2\ For vans, the road load power at 50 mi/h (horsepower) shall be 0.50
  times B (defined in footnote 3 of this table) rounded to the nearest
  \1/2\ horsepower.
\3\ B is the basic vehicle frontal area (square foot) plus the
  additional frontal area (square foot) of mirrors and optional
  equipment exceeding 0.1 ft \2\ which are anticipated to be sold on
  more than 33 percent of the car line. Frontal area measurements shall
  be computed to the nearest 10th of a square foot using a method
  approved in advance by the Administrator.
\4\ For model year 1994 and later heavy light-duty trucks not subject to
  the Tier 0 standards of Sec. 86.094-9, test weight basis is as
  follows: for emissions tests, the basis shall be adjusted loaded
  vehicle weight, as defined in Sec. 86.094-2; and for fuel economy
  tests, the basis shall be loaded vehicle weight, as defined in Sec.
  86.082-2, or, at the manufacturer's option, adjusted loaded vehicle
  weight as defined in Sec. 86.094-2. For all other vehicles, test
  weight basis shall be loaded vehicle weight, as defined in Sec.
  86.082-2.
\5\ Light-duty vehicles over 5,750 lb. loaded vehicle weight shall be
  tested at a 5,500 lb. equivalent test weight.

    (b)-(c) [Reserved]. For guidance see Sec.86.129-80.
    (d) Fuel temperature profile--(1) General requirements. (i) To be 
tested for running losses, as specified in Sec.86.134, a vehicle must 
have a fuel temperature profile. The following procedure is used to 
generate the fuel temperature profile, which serves as a target for 
controlling fuel temperatures during the running loss test. This profile 
represents the fuel temperature change that occurs during on-road 
driving. If a vehicle has more than one fuel tank, a profile shall be 
established for each tank. Manufacturers may also simultaneously 
generate a profile for vapor temperatures.
    (ii) If a manufacturer uses a vehicle model to develop a profile to 
represent multiple models, the vehicle model selected must have the 
greatest expected fuel temperature increase during driving of all those 
models it represents. Also, manufacturers must select test vehicles with 
any available vehicle options that increase fuel temperatures during 
driving (for example, any feature that limits underbody airflow).
    (iii) Manufacturers may conduct testing to develop fuel temperature 
profiles in a laboratory setting, subject to approval by the 
Administrator. The laboratory facility should simulate outdoor testing 
to reproduce fuel and vapor temperature behavior over the specified 
driving schedule. The design of the laboratory facility should include 
consideration of any parameters that may affect fuel temperatures, such 
as solar loading, pavement heat, and relative wind velocities around and 
underneath the test vehicle. Indoor testing to develop the fuel 
temperature profiles must be conducted with little or no vehicle-
specific adjustment of laboratory parameters. Manufacturers would need 
to maintain an ongoing demonstration of correlation between laboratory 
and outdoor measurement of fuel temperatures. Specifically, fuel

[[Page 689]]

temperatures and pressures from indoor driving should be at least as 
high as measured when driving outdoors according to the procedures 
described in this section.
    (iv) Small-volume manufacturers, as defined in Sec.86.094-
14(b)(1), may use an alternate method for generating fuel temperature 
profiles, subject to the approval of the Administrator.
    (v) The Administrator may conduct testing to establish any vehicle's 
temperature profiles or to verify compliance with fuel tank pressure 
requirements.
    (2) Vehicle instrumentation. (i) The vehicle must be equipped with 
temperature sensors and pressure transducers, as described in Sec.
86.107-96 (e) and (f), and a driver's aid, which shall be configured to 
provide the test driver with the desired vehicle speed vs. time trace 
and the actual vehicle speed.
    (ii) A computer, data logger, or strip chart data recorder shall 
record the following parameters at a minimum during the test run:
    (A) Desired speed;
    (B) Actual speed;
    (C) Instantaneous average liquid fuel temperature (Tliq); 
and
    (D) Vapor space pressure (the Administrator may omit measurement of 
fuel tank pressure).
    (iii) The data recording system described in paragraph (d)(2)(ii) of 
this section shall be capable of resolving time to 1 s, capable of resolving temperature to 2 [deg]F, capable of resolving pressure to 1.0 inch of water, and capable of resolving speed to 
1 mph. The temperature and pressure signals shall 
be recorded at intervals of up to 1 minute; speed signals shall be 
recorded at intervals of up to 1 second.
    (3) Ambient conditions. The procedure shall be run under the 
following ambient conditions. Conditions should be representative of 
sunny summer days.
    (i) Starting ambient temperature (Tamb, o) shall be at 
least 95 [deg]F, steady or increasing (no more than 2 [deg]F drop) 
during the procedure. Ambient temperature shall be measured and recorded 
in regular intervals of at least once every 5 minutes. Measure ambient 
temperature with the following requirements (based on Federal Standard 
for Siting Meteorological Sensors at Airports, FCM-S4-1987). The sensors 
shall be mounted 5 1 feet (1.5 0.3 meters) above ground level. The sensors shall be 
protected from radiation from the sun, sky, earth, and any other 
surrounding objects, but at the same time be adequately ventilated. The 
sensors shall be installed in such a position as to ensure that 
measurements are representative of the free air circulation in the 
locality and not influenced by artificial conditions such as large 
buildings, cooling towers, and expanses of concrete and tarmac. Keep any 
grass and vegetation within 100 feet (30 meters) of the sensor clipped 
to a height of about 10 inches (25 centimeters) or less.
    (ii) Wind conditions shall be calm to light with maximum wind speed 
of 15 mph. In the case of temporary gusting, wind speeds between 15 and 
25 mph may occur for up to 5 percent of the total driving time without 
invalidating the data collection. Wind speed shall be measured and 
recorded in regular intervals of at least once per minute. Measure wind 
speed with the following requirements (based on Federal Standard for 
Siting Meteorological Sensors at Airports, FCM-S4-1987). The site should 
be relatively level, but small gradual slopes are acceptable. The sensor 
shall be mounted 30 to 33 feet (9 to 10 meters) above the average ground 
height within a radius of 500 feet (150 meters). The sensor height shall 
not exceed 33 feet, except as necessary to be at least 15 feet (5 
meters) above the height of any obstruction (e.g. vegetation, buildings, 
etc.) within a 500 foot (150 meter) radius. An object is considered to 
be an obstruction if the included lateral angle from the sensor to the 
ends of the object is 10 degrees or more.
    (iii) Road surface temperature shall be at least 125 [deg]F 
throughout the driving period. Pavement temperature shall be measured 
and recorded in regular intervals of at least once per minute. The track 
temperature may be measured with an embedded sensor, a portable 
temperature probe, or an infrared pyrometer that can provide an accuracy 
of 2 [deg]F. Temperatures must be measured on a 
surface representative of the surface where the vehicle is driven.

[[Page 690]]

    (iv) Conditions shall be sunny or mostly sunny with a maximum cloud 
cover of 25 percent.
    (v) Reported cloud cover, wind speed, and ambient temperature should 
be consistent with that reported by the nearest weather station; the 
Administrator may request justification of any discrepancy.
    (4) Profile determination procedure. (i) Drain the fuel tank(s) and 
fill with test fuel to the ``tank fuel volume'' defined in Sec.86.082-
2. The test fuel should meet the specifications of Sec.86.113, except 
that fuel with a lower volatility may be used, subject to Administrator 
approval. Manufacturers using a lower volatility fuel must generate a 
vapor temperature profile for demonstrating compliance with the limit on 
fuel tank pressure during the running loss test (see Sec.86.134-96).
    (ii) The vehicle shall be moved to the location where the data is to 
be collected. It may be driven a maximum distance of 5 miles and may 
also be transported by other means. The vehicle shall be stabilized by 
one of the following methods:
    (A) The vehicle shall be parked for a minimum of 12 hours in an open 
area on a surface that is representative of the test road, without any 
artificial heating or cooling of the fuel. The orientation of the front 
of the vehicle during parking (e.g., N, SW, etc.) shall be documented.
    (B) The vehicle may be soaked in a temperature-controlled 
environment to stabilize fuel temperatures. Before starting the drive, 
the vehicle shall be stabilized with fuel temperatures 95 3 [deg]F for at least one hour. The fuel temperature may 
not exceed 98 [deg]F at any time before the beginning of the driving 
schedule, during which only whole-vehicle heating and cooling may be 
used to control fuel temperatures. If a manufacturer uses the provisions 
of paragraph (d)(7)(v) of this section to establish a lower initial fuel 
temperature for the running loss test, the fuel in the test vehicle may 
not be stabilized at a temperature higher than the newly established 
initial fuel temperature.
    (iii) Once the ambient conditions specified in paragraph (d)(3) of 
this section are met and the vehicle has been stabilized according to 
paragraph (d)(4)(ii) of this section, the vehicle's engine may be 
started. The vehicle's air conditioning system (if so equipped) shall be 
set to the ``normal'' air conditioning mode and adjusted to the minimum 
discharge air temperature and high fan speed. Vehicles equipped with 
automatic temperature controlled air conditioning systems shall be set 
to operate in ``automatic'' temperature and fan modes with the system 
set at 72 [deg]F.
    (iv) The vehicle may be operated at minimum throttle for a period up 
to 60 seconds prior to the start of the driving schedule, as necessary 
to move from the parking location onto the road surface. The driver's 
aid shall be started and the vehicle operated over the driving cycle 
specified in Sec.86.134-96(b) with the transmission operated in the 
same manner as specified in Sec.86.128-79. The data recording system 
shall provide a record of the required parameters over the entire period 
of driving.
    (5) Records required. In addition to the vehicle data recording, the 
following parameters shall be documented for the determination of the 
fuel temperature profile:
    (i) Date and time of vehicle fueling;
    (ii) Odometer reading at vehicle fueling;
    (iii) Date and time vehicle was parked, parking location and 
orientation;
    (iv) Odometer reading at parking;
    (v) Date and time engine was started;
    (vi) Time of initiation of first UDDS;
    (vii) Time of completion of the driving cycle;
    (viii) Ambient temperatures throughout the period of driving 
(Tamb);
    (ix) Wind speed throughout the period of driving;
    (x) Track surface temperatures throughout the period of driving 
cycle (Tsur);
    (xi) Percent cloud cover during the period of driving; and
    (xii) Ambient temperature, wind speed, and percent cloud cover 
reported by the nearest weather station for the time corresponding most 
closely to the period of driving.
    (6) Fuel tank pressure. Tank pressure shall not exceed 10 inches of 
water at any time during the temperature profile determination unless a 
pressurized

[[Page 691]]

system is used and the manufacturer demonstrates that vapor would not be 
vented to the atmosphere upon fuel cap removal.
    (7) Calculation of temperature profiles. (i) The traces from the 
driving schedule shall be verified to meet the speed tolerance 
requirements of Sec.86.115. The following conditions shall be 
verified:
    (A) Tamb, i=Tamb, o-2 [deg]F.

Where,
    (1)i = instantaneous measurement throughout the drive; and
    (2)o = initial measurement at the start of the specified driving 
schedule.
    (B) Tamb, o=95 [deg]F.
    (C) Tsur, i-Tamb, i=30 [deg]F.
    (D) Wmax<=15 mph.
    (ii) Failure to comply with any of these requirements shall result 
in invalidation of the data and require that the procedure be repeated, 
beginning with the fuel drain at paragraph (d)(4)(i) of this section.
    (iii) If all these requirements are met, the following calculations 
shall be performed to determine a profile for liquid fuel temperatures 
and, if applicable, for vapor temperatures:
Ti, profile = Ti-To.

Where:
    (A) Ti,profile = the series of temperatures that comprise 
the relative temperature profile.
    (B) Ti = the series of observed liquid fuel or vapor 
temperatures during the drive.
    (C) To = the liquid fuel or vapor temperature observed at 
the start of the specified driving schedule.
    (iv) The relative temperature profile consists of the set of 
temperatures at each 1-minute interval. If temperatures are sampled more 
frequently than once per minute, the temperature data points may 
represent a rolling average of temperatures sampled for up to one-minute 
intervals. If multiple valid test runs are conducted for any model, then 
all the collected data shall be used to calculate a composite profile, 
based on the average temperatures at each point. The absolute 
temperature profile is determined by adding 95 [deg]F (35 [deg]C) to 
each point of the relative profile. Other methodologies for developing 
corrected liquid fuel and vapor space temperature profiles may be used 
if demonstrated to yield equivalent results and approved in advance by 
the Administrator.
    (v) Manufacturers may use a lower initial fuel temperature for the 
running loss test, if approved in advance by the Administrator. To 
demonstrate the need for such an adjustment, manufacturers would be 
expected to determine the maximum fuel temperature experienced by a 
vehicle during an extended park or after driving one UDDS cycle when 
exposed to the ambient conditions described in paragraph (d)(3) of this 
section. To use this provision, manufacturers would have to show maximum 
fuel temperatures no greater than 92 [deg]F.

Sec.86.130-96  Test sequence; general requirements.

    Paragraphs (a) through (d) of this section are applicable to 
vehicles tested for the FTP test. Paragraph (e) of this section is 
applicable to vehicles tested for the SFTP supplemental tests of air 
conditioning (SC03) and aggressive driving (US06). Paragraph (f) of this 
section is applicable to all emission testing.
    (a)(1) Gasoline- and methanol-fueled vehicles. The test sequence 
shown in figure B96-10 shows the steps encountered as the test vehicle 
undergoes the procedures subsequently described to determine conformity 
with the standards set forth. The full three- diurnal sequence depicted 
in figure B96-10 tests vehicles for all sources of evaporative 
emissions. The supplemental two-diurnal test sequence is designed to 
verify that vehicles sufficiently purge their evaporative canisters 
during the exhaust emission test. Sections 86.132-96, 86.133-96 and 
86.138-96 describe the separate specifications of the supplemental two-
diurnal test sequence.
    (2) Gaseous-fueled vehicles. The test sequence shown in figure B96-
10 shows the steps encountered as the test vehicle undergoes the 
procedures subsequently described to determine conformity with the 
standards set forth, with the exception that the fuel drain and fill and 
precondition canister steps

[[Page 692]]

are not required for gaseous-fueled vehicles. In addition, the 
supplemental two-diurnal test and the running loss test are not 
required.
    (b) The vehicle test for fuel spitback during fuel dispensing is 
conducted as a stand-alone test (see Sec.86.146). This test is not 
required for gaseous-fueled vehicles.
    (c) Ambient temperature levels encountered by the test vehicle shall 
be not less than 68 [deg]F nor more than 86 [deg]F, unless otherwise 
specified. If a different ambient temperature is specified for soaking 
the vehicle, the soak period may be interrupted once for up to 10 
minutes to transport the vehicle from one soak area to another, provided 
the ambient temperature experienced by the vehicle is never below 68 
[deg]F. The temperatures monitored during testing must be representative 
of those experienced by the test vehicle.
    (d) The vehicle shall be approximately level during all phases of 
the test sequence to prevent abnormal fuel distribution.
    (e) The supplemental tests for exhaust emissions related to 
aggressive driving (US06) and air conditioning (SC03) use are conducted 
as stand-alone tests as described in Sec. Sec.86.158 through 86.160. 
These tests may be performed in any sequence that maintains the 
appropriate preconditioning requirements as specified in Sec.86.132.
    (f) If tests are invalidated after collection of emission data from 
previous test segments, the test may be repeated to collect only those 
data points needed to complete emission measurements. Compliance with 
emission standards may be determined by combining emission measurements 
from different test runs. If any emission measurements are repeated, the 
new measurements supersede previous values.

    Effective Date Note: At 86 FR 34366, June 29, 2021, Sec.86.130-96 
was amended, effective July 29, 2021.



Sec.86.131-96  Vehicle preparation.

    (a) For gasoline- and methanol-fueled vehicles prepare the fuel 
tank(s) for recording the temperature of the prescribed test fuel, as 
described in Sec.86.107-96(e).
    (b) Provide additional fittings and adapters, as required, to 
accommodate a fuel drain at the lowest point possible in the tank(s) as 
installed on the vehicle.
    (c) For preconditioning that involves loading the evaporative 
emission canister(s) with butane, provide valving or other means as 
necessary to allow purging and loading of the canister(s).
    (d) For vehicles to be tested for running loss emissions, prepare 
the fuel tank(s) for measuring and recording the temperature and 
pressure of the fuel tank as specified in Sec.86.107-96 (e) and (f). 
Measurement of vapor temperature is optional during the running loss 
test. If vapor temperature is not measured, fuel tank pressure need not 
be measured.
    (e) For vehicles to be tested for running loss emissions, prepare 
the exhaust system by sealing or plugging all detectable sources of 
exhaust gas leaks. The exhaust system shall be tested or inspected to 
ensure that detectable exhaust hydrocarbons are not emitted into the 
running loss enclosure during the running loss test.
    (f) For vehicles to be tested for aggressive driving emissions 
(US06), provide a throttle position sensing signal that is compatible 
with the test dynamometer. This signal provides the input information 
that controls dynamometer dynamic inertia weight adjustments (see 
Sec. Sec.86.108-00(b)(2)(ii) and 86.129-00(f)(2)). If a manufacturer 
chooses not to implement dynamic inertia adjustments for a portion or 
all of their product line, this requirement is not applicable.
    (g) You may disable any AECDs that have been approved solely for 
emergency vehicle applications under paragraph (4) of the definition of 
defeat device in Sec.86.1803. The emission standards do not apply when 
any of these AECDs are active.

Sec.86.132-00  Vehicle preconditioning.

    Applicability. Section 86.132-96 (a) through (c)(1) and (d) through 
(m) and

[[Page 693]]

paragraph (c)(2) of this section are applicable to FTP and evaporative 
emission testing. Paragraphs (n) and (o) of this section are applicable 
to vehicles tested for the SFTP supplemental tests of aggressive driving 
(US06) and air conditioning (SC03). Section 86.132-00 includes text that 
specifies requirements that differ from Sec.86.132-96. Where a 
paragraph in Sec.86.132-96 is identical and applicable to Sec.
86.132-00, this may be indicated by specifying the corresponding 
paragraph and the statement ``[Reserved]. For guidance see Sec.86.132-
96.''
    (a)-(c)(1) [Reserved]. For guidance see Sec.86.132-96.
    (c)(2)(i) Once a test vehicle has completed the refueling and 
vehicle soak steps specified in Sec.86.132-96 (b) and (c)(1), these 
steps may be omitted in subsequent testing with the same vehicle and the 
same fuel specifications, provided the vehicle remains under laboratory 
ambient temperature conditions for at least 6 hours before starting the 
next test. In such cases, each subsequent test shall begin with the 
preconditioning drive specified in Sec.86.132-96(c)(1). The test 
vehicle may not be used to set dynamometer horsepower.
    (ii) The SFTP test elements of aggressive driving (US06) and air 
conditioning (SC03) can be run immediately or up to 72 hours after the 
official FTP and/or evaporative test sequence without refueling provided 
the vehicle has remained under laboratory ambient temperature 
conditions. If the time interval exceeds 72 hours or the vehicle leaves 
the ambient temperature conditions of the laboratory, the manufacturer 
must repeat the refueling operation.
    (d)-(m) [Reserved]. For guidance see Sec.86.132-96.
    (n) Aggressive Driving Test (US06) Preconditioning. (1) If the US06 
test follows the exhaust emission FTP or evaporative testing, the 
refueling step may be deleted and the vehicle may be preconditioned 
using the fuel remaining in the tank (see paragraph (c)(2)(ii) of this 
section). The test vehicle may be pushed or driven onto the test 
dynamometer. Acceptable cycles for preconditioning are as follows:
    (i) Preconditioning may consist of a 505, 866, highway, US06 or SC03 
test cycles.
    (ii) [Reserved]
    (iii) If a manufacturer has concerns about fuel effects on adaptive 
memory systems, a manufacturer may precondition a test vehicle on test 
fuel and the US06 cycle. Upon request from a manufacturer, the 
administrator will also perform the preconditioning with the US06 cycle.
    (iv) The preconditioning cycles for the US06 test schedule are 
conducted at the same ambient test conditions as the certification US06 
test.
    (2) Following the preconditioning specified in paragraphs (n)(1)(i), 
(ii), and (iii) of this section, the test vehicle is returned to idle 
for one to two minutes before the start of the official US06 test cycle.
    (o) Air Conditioning Test (SC03) Preconditioning. (1) If the SC03 
test follows the exhaust emission FTP or evaporative testing, the 
refueling step may be deleted and the vehicle may be preconditioned 
using the fuel remaining in the tank (see paragraph (c)(2)(ii) of this 
section). The test vehicle may be pushed or driven onto the test 
dynamometer. Acceptable cycles for preconditioning are as follows:
    (i) If the soak period since the last exhaust test element is less 
than or equal to two hours, preconditioning may consist of a 505, 866, 
or SC03 test cycles.
    (ii) If the soak period since the last exhaust test element is 
greater than two hours, preconditioning consists of one full Urban 
Dynamometer Driving Cycle. Manufacturers, at their option, may elect to 
use the preconditioning in paragraph (o)(1)(i) of this section when the 
soak period exceeds two hours.
    (2) Following the preconditioning specified in paragraphs (o)(1)(i) 
and (ii) of this section, the test vehicle is turned off, the vehicle 
cooling fan(s) is turned off, and the vehicle is allowed to soak for 10 
minutes prior to the start of the official SC03 test cycle.
    (3) The preconditioning cycles for the SC03 air conditioning test 
and the 10 minute soak are conducted at the same

[[Page 694]]

ambient test conditions as the SC03 certification air conditioning test.

Sec.86.132-96  Vehicle preconditioning.

    (a) Fuel tank cap(s) of gasoline- and methanol-fueled vehicles shall 
be removed during any period that the vehicle is parked outdoors 
awaiting testing, to prevent unusual loading of the canisters. During 
this time care must be taken to prevent entry of water or other 
contaminants into the fuel tank. During storage in the test area while 
awaiting testing, the fuel tank cap(s) may be in place. The vehicle 
shall be moved into the test area and the following operations 
performed.
    (b)(1) Gasoline- and Methanol-Fueled Vehicles. Drain the fuel 
tank(s) and fill with test fuel, as specified in Sec.86.113, to the 
``tank fuel volume'' defined in Sec.86.082-2. The fuel cap(s) shall be 
installed within one minute after refueling.
    (2) Gaseous-Fueled Vehicles. Vehicle fuel tanks to be filled with 
fuel that meets the specifications in Sec.86.113. Fuel tanks shall be 
filled to a minimum of 75% of service pressure for natural gas-fueled 
vehicles or a minimum of 75% of available fill volume for liquefied 
petroleum gas-fueled vehicles. Prior draining of the fuel tanks is not 
called for if the fuel in the tanks already meets the specifications in 
Sec.86.113.
    (c)(1) Gasoline- and methanol-fueled vehicles shall be soaked for at 
least 6 hours after being refueled. Petroleum-fueled diesel vehicles and 
gaseous-fueled vehicles shall be soaked for at least 1 hour after being 
refueled. Following this soak period, the test vehicle shall be placed, 
either by being driven or pushed, on a dynamometer and operated through 
one Urban Dynamometer Driving Schedule (UDDS), specified in Sec.86.115 
and appendix I of this part.
    (2) Once a test vehicle has completed the refueling and vehicle soak 
steps specified in paragraphs (b) and (c)(1) of this section, these 
steps may be omitted in subsequent testing with the same vehicle and the 
same fuel specifications, provided the vehicle remains under laboratory 
ambient temperature conditions for at least 6 hours before starting the 
next test. In such cases, each subsequent test shall begin with the 
preconditioning drive specified in this paragraph. The test vehicle may 
not be used to set dynamometer horsepower.
    (d) For unusual circumstances where the need for additional 
preconditioning is demonstrated by the manufacturer, such 
preconditioning may be allowed with the advance approval of the 
Administrator.
    (e) The Administrator may also choose to conduct or require to be 
conducted additional preconditioning to ensure that the evaporative 
emission control system is stabilized in the case of gasoline-fueled and 
methanol-fueled vehicles, or to ensure that the exhaust system is 
stabilized in the case of petroleum- and methanol-fueled diesel 
vehicles. The preconditioning shall consist of one of the following:
    (1) For gasoline- and methanol-fueled vehicles. (i) Additional 
preconditioning shall consist of no more than 50 miles of mileage 
accumulation under typical driving conditions, either on the road or on 
a dynamometer.
    (ii) In the case of repeat testing on a flexible-fueled vehicle, in 
which the test fuel is changed, the following preconditioning procedure 
shall be used. This additional preconditioning allows the vehicle to 
adapt to the new fuel before the next test run.
    (A) Purge the vehicle's evaporative canister for 60 minutes at 0.8 
cfm.
    (B) Drain the fuel tank(s) and fill with 3 gallons of the test fuel.
    (C) Start the vehicle and allow it to idle for 1 minute.
    (D) Drain the fuel tank(s) and fill with the new test fuel to the 
``tank fuel volume'' defined in Sec.86.082-2. The average temperature 
of the dispensed fuel shall be less than 60 [deg]F.
    (E) Conduct a heat build according to the procedure specified in 
Sec.86.133-90.
    (F) The vehicle shall be placed, either by being driven or pushed, 
on a dynamometer and operated through one UDDS, specified in Sec.
86.115 and appendix I of this part.
    (G) Following the dynamometer drive, the vehicle shall be turned off 
for 5 minutes, then restarted and allowed to idle for 1 minute. The 
vehicle shall

[[Page 695]]

then be turned off for 1 minute, and allowed to idle again for 1 minute.
    (H) After the vehicle is turned off the last time, it may be tested 
for evaporative and exhaust emissions, starting with paragraph (a) of 
this section.
    (2) For petroleum-fueled diesel, methanol-fueled diesel, and 
gaseous-fueled vehicles. The preconditioning shall consist of either of 
the following:
    (i) An initial one hour minimum soak and, one, two, or three driving 
cycles of the UDDS, as described in paragraph (c) of this section, each 
followed by a soak of at least one hour with engine off, engine 
compartment cover closed and cooling fan off. The vehicle may be driven 
off the dynamometer following each UDDS for the soak period; or
    (ii) For abnormally treated vehicles, as defined in Sec.86.085-2 
or Sec.86.1803-01 as applicable, two Highway Fuel Economy Driving 
Schedules, found in 40 CFR part 600, appendix I, run in immediate 
succession, with the road load power set at twice the value obtained 
from Sec.86.129-80.
    (f)(1) Gasoline- and methanol-fueled vehicles. After completion of 
the preconditioning drive, the vehicle shall be driven off the 
dynamometer. The vehicle's fuel tank(s) shall be drained and then filled 
with test fuel, as specified in Sec.86.113, to the ``tank fuel 
volume'' defined in Sec.86.082-2. The vehicle shall be refueled within 
1 hour after completion of the preconditioning drive. The fuel cap(s) 
shall be installed within 1 minute after refueling. The vehicle shall be 
parked within five minutes after refueling.
    (2) Petroleum-fueled diesel vehicles. Within five minutes after 
completion after the preconditioning drive, the vehicle shall be driven 
off the dynamometer and parked.
    (3) Gaseous-fueled vehicles. After completion of the preconditioning 
drive, the vehicle shall be driven off the dynamometer. Vehicle fuel 
tanks shall be refilled with fuel that meets the specifications in Sec.
86.113. Fuel tanks shall be filled to a minimum of 75% of service 
pressure for natural gas-fueled vehicles or a minimum of 75% of 
available fill volume for liquefied petroleum gas-fueled vehicles. Prior 
draining of the fuel tanks is not called for if the fuel in the tanks 
already meets the specifications in Sec.86.113. The vehicle shall be 
parked within five minutes after refueling, or, in the absence of 
refueling, within five minutes after completion of the preconditioning 
drive.
    (g) The vehicle shall be soaked for not less than 12 hours nor more 
than 36 hours between the end of the refueling event and the beginning 
of the cold start exhaust emission test.
    (h) During the soak period for the three-diurnal test sequence 
described in Sec.86.130-96, evaporative canisters, if the vehicle is 
so equipped, shall be preconditioned according to the following 
procedure. For vehicles with multiple canisters in a series 
configuration, the set of canisters must be preconditioned as a unit. 
For vehicles with multiple canisters in a parallel configuration, each 
canister must be preconditioned separately. If production evaporative 
canisters are equipped with a functional service port designed for vapor 
load or purge steps, the service port shall be used during testing to 
precondition the canister. In addition, for model year 1998 and later 
vehicles equipped with refueling canisters, these canisters shall be 
preconditioned for the three-diurnal test sequence according to the 
procedure in paragraph (j)(1) of this section. If a vehicle is designed 
to actively control evaporative or refueling emissions without a 
canister, the manufacturer shall devise an appropriate preconditioning 
procedure, subject to the approval of the Administrator.
    (1)(i) Prepare the evaporative emission canister for the canister 
purging and loading operation. The canister shall not be removed from 
the vehicle, unless access to the canister in its normal location is so 
restricted that purging and loading can only reasonably be accomplished 
by removing the canister from the vehicle. Special care shall be taken 
during this step to avoid damage to the components and the integrity of 
the fuel system. A replacement canister may be temporarily installed 
during the soak period while the canister from the test vehicle is 
preconditioned.
    (ii) The canister purge shall be performed with ambient air of 
humidity controlled to 5025 grains per pound of 
dry air. This may be accomplished by purging the canister in a room that 
is

[[Page 696]]

conditioned to this level of absolute humidity. The flow rate of the 
purge air shall be maintained at a nominal flow rate of 0.8 cfm and the 
duration shall be determined to provide a total purge volume flow 
through the canister equivalent to 300 canister bed volume exchanges. 
The bed volume is based on the volume of adsorbing material in the 
canister.
    (iii) The evaporative emission canister shall then be loaded by 
sending to the canister an amount of commercial grade butane vapors 
equivalent to 1.5 times its nominal working capacity. The canister shall 
be loaded with a mixture composed of 50 percent butane and 50 percent 
nitrogen by volume at a rate of 152 grams butane 
per hour. If the canister loading at that rate takes longer than 12 
hours, a manufacturer may determine a new rate, based on completing the 
canister loading in no less than 12 hours. The new rate may be used for 
all subsequent canister loading according to paragraph (h) of this 
section. The time of initiation and completion of the canister loading 
shall be recorded.
    (iv) The determination of a canister's nominal working capacity 
shall be based on the average capacity of no less than five canisters 
that are in a stabilized condition.
    (A) For stabilization, each canister must be loaded no less than 10 
times and no more than 100 times to 2-gram breakthrough with a 50/50 
mixture by volume of butane and nitrogen, at a rate of 15 grams butane 
per hour. Each canister loading step must be preceded by canister 
purging with 300 canister bed volume exchanges at 0.8 cfm.
    (B) For determining working capacity, each canister must first be 
purged with 300 canister bed volume exchanges at 0.8 cfm. The working 
capacity of each canister shall be established by determining the mass 
of butane required to load the canister from the purged state so that it 
emits 2 grams of hydrocarbon vapor; the canister must be loaded with a 
50/50 mixture by volume of butane and nitrogen, at a rate of 15 grams 
butane per hour.
    (2) For methanol-fueled and flexible-fueled vehicles, canister 
preconditioning shall be performed with a fuel vapor composition 
representative of that which the vehicle would generate with the fuel 
mixture used for the current test. Manufacturers shall develop a 
procedure to precondition the evaporative canister, if the vehicle is so 
equipped, for the different fuel. The procedure shall represent a 
canister loading equivalent to that specified in paragraph (h)(1) of 
this section and shall be approved in advance by the Administrator.
    (i) [Reserved]
    (j) For the supplemental two-diurnal test sequence described in 
Sec.86.130-96, one of the following methods shall be used to 
precondition evaporative canisters during the soak period specified in 
paragraph (g) of this section. For vehicles with multiple canisters in a 
series configuration, the set of canisters must be preconditioned as a 
unit. For vehicles with multiple canisters in a parallel configuration, 
each canister must be preconditioned separately. In addition, for model 
year 1998 and later vehicles equipped with refueling canisters, these 
canisters shall be preconditioned for the supplemental two-diurnal test 
sequence according to the procedure in paragraph (j)(1) of this section. 
Canister emissions are measured to determine breakthrough. Breakthrough 
is here defined as the point at which the cumulative quantity of 
hydrocarbons emitted is equal to 2 grams.
    (1) Butane loading to breakthrough. The following procedure provides 
for emission measurement in an enclosure. Breakthrough may also be 
determined by measuring the weight gain of an auxiliary evaporative 
canister connected downstream of the vehicle's canister, in which case, 
the following references to the enclosure can be ignored. The auxiliary 
canister shall be well purged prior to loading. If production 
evaporative canisters are equipped with a functional service port 
designed for vapor load or purge steps, the service port shall be used 
during testing to precondition the canister.
    (i) Prepare the evaporative/refueling emission canister for the 
canister loading operation. The canister shall not be removed from the 
vehicle, unless access to the canister in its normal location is so 
restricted that purging and

[[Page 697]]

loading can only reasonably be accomplished by removing the canister 
from the vehicle. Special care shall be taken during this step to avoid 
damage to the components and the integrity of the fuel system. A 
replacement canister may be temporarily installed during the soak period 
while the canister from the test vehicle is preconditioned.
    (ii) The evaporative emission enclosure shall be purged for several 
minutes. Warning: If at any time the concentration of hydrocarbons, of 
methanol, or of methanol and hydrocarbons exceeds 15,000 ppm C the 
enclosure should be immediately purged. This concentration provides at 
least a 4:1 safety factor against the lean flammability limit.
    (iii) The FID hydrocarbon analyzer shall be zeroed and spanned 
immediately prior to the canister loading procedure.
    (iv) If not already on, the evaporative enclosure mixing fan shall 
be turned on at this time.
    (v) Place the vehicle in a sealed enclosure and measure emissions 
with a FID.
    (vi)(A) For gasoline-fueled vehicles, load the canister with a 
mixture composed of 50 percent butane and 50 percent nitrogen by volume 
at a rate of 40 grams butane per hour.
    (B) For methanol-fueled and flexible-fueled vehicles, canister 
preconditioning shall be performed with a fuel vapor composition 
representative of that which the vehicle would generate with the fuel 
mixture used for the current test. Manufacturers shall develop a 
procedure to precondition the evaporative canister, if the vehicle is so 
equipped, for the different fuel.
    (vii) As soon as the canister reaches breakthrough, the vapor source 
shall be shut off.
    (viii) Reconnect the evaporative/refueling emission canister and 
restore the vehicle to its normal operating condition.
    (2) Load with repeated diurnal heat builds to breakthrough. The 
following procedure provides for emission measurement in an enclosure. 
Breakthrough may also be determined by measuring the weight gain of an 
auxiliary evaporative canister connected downstream of the vehicle's 
canister, in which case, the following references to the enclosure can 
be ignored. The auxiliary canister shall be well purged with dry air 
prior to loading.
    (i) The evaporative emission enclosure shall be purged for several 
minutes. Warning: If at any time the concentration of hydrocarbons, of 
methanol, or of methanol and hydrocarbons exceeds 15,000 ppm C the 
enclosure should be immediately purged. This concentration provides at 
least a 4:1 safety factor against the lean flammability limit.
    (ii) The FID hydrocarbon analyzer shall be zeroed and spanned 
immediately prior to the diurnal heat builds.
    (iii) If not already on, the evaporative enclosure mixing fan shall 
be turned on at this time.
    (iv) The fuel tank(s) of the prepared vehicle shall be drained and 
filled with test fuel, as specified in Sec.86.113, to the ``tank fuel 
volume'' defined in Sec.86.082-2. The average temperature of the 
dispensed fuel shall be 6012 [deg]F (167 [deg]C). The fuel tank cap(s) shall be installed 
within 1 minute after refueling.
    (v) Within one hour of being refueled, the vehicle shall be placed, 
with the engine shut off, in the evaporative emission enclosure. The 
fuel tank temperature sensor shall be connected to the temperature 
recording system. A heat source, specified in Sec.86.107-90(a)(4), 
shall be properly positioned with respect to the fuel tank(s) and 
connected to the temperature controller.
    (vi) The temperature recording system shall be started.
    (vii) The fuel may be artificially heated to the starting diurnal 
temperature.
    (viii) When the fuel temperature reaches at least 69 [deg]F (21 
[deg]C), immediately: turn off purge blower (if not already off); close 
and seal enclosure doors; and initiate measurement of the hydrocarbon 
level in the enclosure.
    (ix) When the fuel temperature reaches 722 
[deg]F (221 [deg]C), start the diurnal heat build.
    (x) The fuel shall be heated in such a way that its temperature 
change conforms to the following function to within 4 [deg]F (3 [deg]C):

F = To + 0.4t; or


[[Page 698]]



for SI units,

C = To + (2/9)t.

Where,

F = fuel temperature, [deg]F;
C = fuel temperature, [deg]C;
t = time since beginning of test, minutes; and
To = initial temperature in [deg]F ([deg]C for SI units).

    (xi) As soon as breakthrough occurs or when the fuel temperature 
reaches 96 [deg]F (36 [deg]C), whichever occurs first, the heat source 
shall be turned off, the enclosure doors shall be unsealed and opened, 
and the vehicle fuel tank cap(s) shall be removed. If breakthrough has 
not occurred by the time the fuel temperature reaches 96 [deg]F (36 
[deg]C), the heat source shall be removed from the vehicle, the vehicle 
shall be removed (with engine still off) from the evaporative emission 
enclosure and the entire procedure outlined in paragraph (j)(2) of this 
section shall be repeated until breakthrough occurs.
    (xii) After breakthrough occurs, the fuel tank(s) of the prepared 
vehicle shall be drained and filled with test fuel, as specified in 
Sec.86.113, to the ``tank fuel volume'' defined in Sec.86.082-2. The 
fuel shall be stabilized to a temperature within 3 [deg]F of the lab 
ambient before beginning the driving cycle for the exhaust emission 
test.
    (k) [Reserved]
    (l) Vehicles to be tested for exhaust emissions only shall be 
processed according to Sec. Sec.86.135 through 86.137. Vehicles to be 
tested for evaporative emissions shall be processed in accordance with 
the procedures in Sec. Sec.86.133 through 86.138, starting with Sec.
86.135.
    (m) Vehicles to be tested for evaporative emissions with the 
supplemental two-diurnal test sequence described in Sec.86.130-96, 
shall proceed according to Sec. Sec.86.135 through 86.137, followed by 
the supplemental hot soak test (see Sec.86.138-96(k)) and the 
supplemental diurnal emission test (see Sec.86.133-96(p)).
    (n) With prior approval of the Administrator, manufacturers may use 
an alternative canister loading method in lieu of the applicable 
canister loading method described in the provisions of paragraphs (h), 
(j)(1) and (j)(2) of this section, provided the alternative method is 
shown to be equivalent or result in a more fully loaded canister (a 
canister that has adsorbed an equal or greater amount of hydrocarbon 
vapors) than the applicable canister loading method required by the 
provisions of paragraphs (h), (j)(1) and (j)(2) of this section. 
Additionally, the Administrator may conduct confirmatory certification 
testing and in-use testing using the alternative canister loading method 
used by the manufacturer to test applicable certification and/or in-use 
vehicles or the appropriate method outlined in the provisions of 
paragraphs (h), (j)(1) and (j)(2) of this section.

Sec.86.133-96  Diurnal emission test.

    (a)(1) The diurnal emission test for gasoline-, methanol- and 
gaseous-fueled vehicles consists of three 24-hour test cycles following 
the hot soak test. Emissions are measured for each 24-hour cycle, with 
the highest emission level used to determine compliance with the 
standards specified in subpart A of this part. The Administrator may 
truncate a test after any 24-hour cycle without affecting the validity 
of the collected data. Sampling of emissions from the running loss and 
hot soak tests is not required as preparation for the diurnal emission 
test. The diurnal emission test may be conducted as part of either the 
three- diurnal test sequence or the supplemental two-diurnal test 
sequence, as described in Sec.86.130-96.
    (2) For the full three-diurnal test sequence, the diurnal emission 
test outlined in paragraphs (b) through (o) of this section follows the 
high-temperature hot soak test concluded in Sec.86.138-96(j).
    (3) For the supplemental two-diurnal test sequence, the diurnal 
emission test outlined in paragraph (p) of this section follows the 
alternate hot soak test specified in Sec.86.138-96(k). This test is 
not required for gaseous-fueled vehicles.
    (b) The test vehicle shall be soaked for not less than 6 hours nor 
more than 36 hours between the end of the hot

[[Page 699]]

soak test and the start of the diurnal emission test. For at least the 
last 6 hours of this period, the vehicle shall be soaked at 
72[deg]3 [deg]F. The temperature tolerance may be 
waived for up to 10 minutes to allow purging of the enclosure or 
transporting the vehicle into the enclosure at the beginning of the 
diurnal emission test.
    (c) The test vehicle shall be exposed to ambient temperatures cycled 
according to the profile specified in Sec.86.133 and appendix II of 
this part.
    (1) Temperatures measured with the underbody temperature sensor 
shall follow the profile with a maximum deviation of 3 [deg]F at any 
time and an average temperature deviation not to exceed 2 [deg]F, where 
the average deviation is calculated using the absolute value of each 
measured deviation. In addition, the temperature from the sidewall 
temperature sensors shall follow the profile with a maximum deviation of 
5 [deg]F at any time.
    (2) Ambient temperatures shall be measured at least every minute. 
Temperature cycling shall begin when time = 0 minutes, as specified in 
paragraph (i)(5) of this section.
    (d) The diurnal enclosure shall be purged for several minutes prior 
to the test. Warning: If at any time the concentration of hydrocarbons, 
of methanol or of methanol and hydrocarbons exceeds 15,000 ppm C the 
enclosure should be immediately purged. This concentration provides at 
least a 4:1 safety factor against the lean flammability limit.
    (e) The test vehicle, with the engine shut off and the test vehicle 
windows and luggage compartment(s) opened, shall be moved into the 
diurnal enclosure.
    (f)-(g) [Reserved]
    (h) Prior to sampling for emissions and throughout the period of 
cycled ambient temperatures, the mixing fan(s) shall circulate the air 
at a rate of 0.80.2 cfm per cubic foot of ambient 
volume. The mixing fan(s), plus any additional fans if needed, shall 
also maintain a minimum wind speed of 5 mph (8 km/hr) under the fuel 
tank of the test vehicle. The Administrator may adjust fan speed and 
location to ensure sufficient air circulation around the fuel tank. The 
wind speed requirement may be satisfied by consistently using a fan 
configuration that has been demonstrated to maintain a broad 5-mph air 
flow in the vicinity of the vehicle's fuel tank, subject to verification 
by the Administrator.
    (i) Emission sampling may begin as follows:
    (1) The FID (or HFID) hydrocarbon analyzer shall be zeroed and 
spanned immediately prior to the sampling.
    (2) Impingers charged with known volumes of pure deionized water 
shall be placed in the methanol sampling system (methanol-fueled 
vehicles only).
    (3) Turn off purge blowers (if not already off).
    (4) Close and seal enclosure doors (if not already closed and 
sealed).
    (5) Within 10 minutes of closing and sealing the doors, analyze 
enclosure atmosphere for hydrocarbons and record. This is the initial 
(time = 0 minutes) hydrocarbon concentration, CHCi, required 
in Sec.86.143. Hydrocarbon emissions may be sampled continuously 
during the test period.
    (6) Analyze the enclosure atmosphere for methanol, if applicable, 
and record. The methanol sampling must start simultaneously with the 
initiation of the hydrocarbon analysis and continue for 4.00.5 minutes. This is the initial methanol concentration, 
CCH3OHi, required in Sec.86.143. Record the time 
elapsed during this analysis. If the 4-minute sample period is 
inadequate to collect a sample of sufficient concentration to allow 
accurate GC analysis, rapidly collect the methanol sample in a bag and 
then bubble the bag sample through the impingers at the specified flow 
rate. The time elapsed between collection of the bag sample and flow 
through the impingers should be minimized to prevent any losses. If the 
test is conducted in a fixed-volume enclosure that allows airflow into 
and out of the enclosure, the effect of makeup air dilution must be 
factored into the analysis.
    (j) If testing indicates that a vehicle design may result in fuel 
temperature responses during enclosure testing that are not 
representative of in-use summertime conditions, the Administrator may 
adjust air circulation and temperature during the test as needed to

[[Page 700]]

ensure that the test sufficiently duplicates the vehicle's in-use 
experience.
    (k) The FID (or HFID) hydrocarbon analyzer shall be zeroed and 
spanned immediately prior to the end of each emission sampling period.
    (l) Fresh impingers shall be installed in the methanol collection 
system immediately prior to the end of each emission measurement, if 
applicable.
    (m) The end of the first, second, and third emission sampling period 
shall occur 14406, 28806, 
43206 minutes, respectively, after the beginning 
of the initial sampling, as specified in paragraph (i)(5) of this 
section.
    (1) At the end of each emission sampling period, analyze the 
enclosure atmosphere for hydrocarbons and record. This is the final 
hydrocarbon concentration, CHCf, required in Sec.86.143. 
The emission measurement at the end of each period becomes the initial 
hydrocarbon concentration, CHCi, of the next emission 
sampling period.
    (2) Analyze the enclosure atmosphere for methanol, if applicable, 
and record. The methanol sampling must start simultaneously with the 
initiation of the hydrocarbon analysis and continue for 4.00.5 minutes. This is the final (time = 1440 minutes) 
methanol concentration, CCH3OHf, required in Sec.
86.143. Record the time elapsed during this analysis. If the 4-minute 
sample period is inadequate to collect a sample of sufficient 
concentration to allow accurate GC analysis, rapidly collect the 
methanol sample in a bag and then bubble the bag sample through the 
impingers at the specified flow rate. The time elapsed between 
collection of the bag sample and flow through the impingers should be 
minimized to prevent any losses. If the test is conducted in a fixed-
volume enclosure that allows airflow into and out of the enclosure, the 
effect of makeup air dilution must be factored into the analysis.
    (n) At the end of the temperature cycling period the enclosure doors 
shall be unsealed and opened, the test vehicle windows and luggage 
compartments may be closed and the test vehicle, with the engine shut 
off, shall be removed from the enclosure.
    (o) This completes the full three-diurnal evaporative emission test 
sequence described in Sec.86.130-96.
    (p) For the supplemental two-diurnal test sequence described in 
Sec.86.130-96, the following steps shall be performed in lieu of the 
steps described in paragraphs (b) through (n) of this section.
    (1) For the supplemental two-diurnal test sequence, the test vehicle 
shall be soaked for not less than 6 hours nor more than 36 hours between 
the end of the hot soak test described in Sec.86.138-96(k), and the 
start of the two-diurnal emission test. For at least the last 6 hours of 
this period, the vehicle shall be soaked at 723 
[deg]F.
    (2) The vehicle shall be tested for diurnal emissions according to 
the procedures specified in paragraphs (c) through (n) of this section, 
except that the test includes only two 24-hour periods. Therefore the 
end of the first and second emission sampling periods shall occur 
14406 and 28806 minutes, 
respectively, after the initial sampling.
    (3) This completes the supplemental two-diurnal test sequence for 
evaporative emission measurement.

Sec.86.134-96  Running loss test.

    (a) Overview. Gasoline- and methanol-fueled vehicles are to be 
tested for running loss emissions during simulated high-temperature 
urban driving; this test is not required for gaseous-fueled vehicles. 
During operation, tank temperatures are controlled according to a 
prescribed profile to simulate in-use conditions. If the vehicle is 
determined to have exceeded the standard before the end of the running 
loss test, the test may be terminated without invalidating the data. The 
test can be run either in a sealed enclosure or with the point-source 
method, as specified in paragraph (g) of this section. Measurement of 
vapor temperature is optional during the running loss test; however, if 
testing by the Administrator shows that a vehicle has exceeded an 
emission standard without measurement of vapor temperatures, the 
manufacturer may, utilizing its own resources, conduct subsequent 
testing on that vehicle to determine if the exceedance is attributable 
to inadequate control of vapor temperatures.

[[Page 701]]

    (b) Driving schedule. Conduct the running loss test by operating the 
test vehicle through one Urban Dynamometer Driving Schedule (UDDS), a 2-
minute idle, two New York City Cycles, another 2-minute idle, another 
UDDS, then another 2-minute idle (see Sec.86.115 and appendix I of 
this part). Fifteen seconds after the engine starts, place the 
transmission in gear. Twenty seconds after the engine starts, begin the 
initial vehicle acceleration of the driving schedule. The transmission 
shall be operated according to the specifications of Sec.86.128 during 
the driving cycles.
    (c) Dynamometer operation. (1) The exhaust from the vehicle must be 
routed outside the test cell or enclosure. Exhaust gases may, but need 
not, be collected and sampled.
    (2) Provisions of Sec.86.135-90(c) shall apply.
    (3) Practice runs over the prescribed driving schedule may not be 
performed at test point.
    (4) Provisions of Sec.86.135-90 (e) and (f) shall apply.
    (5) If the dynamometer horsepower must be adjusted manually, it 
shall be set within 1 hour prior to the running loss test phase. The 
test vehicle shall not be used to make this adjustment. Dynamometers 
using automatic control of preselectable power settings may be set any 
time prior to the beginning of the emissions test.
    (6) Dynamometer roll or shaft revolutions shall be used to determine 
the actual driving distance for the running loss test, DRL, 
required in Sec.86.143. The revolutions shall be measured on the same 
roll or shaft used for measuring the vehicle's speed.
    (7) Provisions of Sec.86.135-90(i) shall apply.
    (8) The test run may be stopped if a warning light or gauge 
indicates that the vehicle's engine coolant has overheated.
    (d) Engine starting and restarting. (1) Provisions of Sec.86.136-
90(a) shall apply.
    (2) If the vehicle does not start after the manufacturer's 
recommended cranking time (or 10 continuous seconds in the absence of a 
manufacturer's recommendation), cranking shall cease for the period 
recommended by the manufacturer (or 10 seconds in the absence of a 
manufacturer's recommendation). This may be repeated for up to three 
start attempts. If the vehicle does not start after three attempts, the 
reason for failure to start shall be determined. If failure to start is 
an operational error, the vehicle shall be rescheduled for testing, 
starting with the soak period immediately preceding the running loss 
test.
    (3) If failure to start is caused by a vehicle malfunction, 
corrective action of less than 30 minutes duration may be taken 
(according to Sec.86.090-25), and the test continued, provided that 
the ambient conditions to which the vehicle is exposed are maintained at 
955 [deg]F (353 [deg]C). 
When the engine starts, the timing sequence of the driving schedule 
shall begin. If failure to start is caused by vehicle malfunction and 
the vehicle cannot be started, the test shall be voided, the vehicle 
removed from the dynamometer, and corrective action may be taken 
according to Sec.86.090-25. The reason for the malfunction (if 
determined) and the corrective action taken shall be reported to the 
Administrator.
    (4) Provisions of Sec.86.136-90(e) shall apply.
    (e) Pressure checks. No pressure checks of the evaporative system 
shall be allowed. Under no circumstances will any changes/repairs to the 
evaporative emissions control system be allowed.
    (f) Temperature stabilization. Immediately after the hot transient 
exhaust emission test, the vehicle shall be soaked in a temperature 
controlled area for a maximum of 6 hours until the fuel temperature is 
stabilized. The fuel may be heated or cooled to stabilize fuel 
temperatures, but the fuel heating rate must not exceed 5 [deg]F in any 
1-hour interval during the soak period. A manufacturer may use a faster 
heating rate or a longer period for stabilizing fuel temperatures if the 
needed heating cannot be easily accomplished in the 6-hour period, 
subject to Administrator approval.
    (1) Fuel temperatures must be held at 95 3 
[deg]F for at least one hour before the start of the running loss test.
    (2) If a vehicle's fuel temperature profile has an initial 
temperature lower than 95 [deg]F, as described in

[[Page 702]]

Sec.86.129-94(d)(7)(v), the fuel in the test vehicle must be 
stabilized to within 3 [deg]F of that temperature for at least one hour 
before the start of the running loss test.
    (g) Running loss test. The running loss test may be conducted either 
by the enclosure method, or by the point-source method.
    (1) Enclosure method. (i) The running loss enclosure shall be purged 
for several minutes immediately prior to the test. Warning: If at any 
time the concentration of hydrocarbons, of methanol, or of methanol and 
hydrocarbons exceeds 15,000 ppm C the enclosure should be immediately 
purged. This concentration provides at least a 4:1 safety factor against 
the lean flammability limit.
    (ii) The FID hydrocarbon analyzer shall be zeroed and spanned 
immediately prior to the test.
    (iii) If not already on, the running loss enclosure mixing fan(s) 
shall be turned on at this time. Throughout the test, the mixing fan(s) 
shall circulate the air at a rate of at least 1.0 cfm per cubic foot of 
ambient volume.
    (iv) The test vehicle, with the engine off, shall be moved onto the 
dynamometer in the running loss enclosure. The vehicle engine 
compartment cover shall be unlatched, but closed as much as possible, 
allowing for the air intake equipment specified in paragraph (g)(1)(vii) 
of this section. The vehicle engine compartment cover may be closed if 
alternate routing is found for the air intake equipment. Any windows, 
doors, and luggage compartments shall be closed. A window may be opened 
to direct cooling air into the passenger compartment of the vehicle, if 
the vehicle is not equipped with its own air conditioning.
    (v) Fans shall be positioned as described in Sec. Sec.86.107-96 
(d) and (h).
    (vi) Set vehicle air conditioning controls as described in 40 CFR 
1066.835.
    (vii) Connect the air intake equipment to the vehicle, if 
applicable. This connection shall be made to minimize leakage.
    (viii) The temperature and pressure recording systems shall be 
started. Measurement of vapor temperature is optional during the running 
loss test. If vapor temperature is not measured, fuel tank pressure need 
not be measured.
    (ix) Turn off purge blowers (if not already off).
    (x) The temperature of the liquid fuel shall be monitored and 
recorded at least every 15 seconds with the temperature recording system 
specified in Sec.86.107-96(e).
    (xi) Close and seal the enclosure doors.
    (xii) When the ambient temperature is 955 
[deg]F (353 [deg]C) and the fuel has been 
stabilized according to paragraph (f) of this section, the running loss 
test may begin. Measure the initial ambient temperature and pressure.
    (A) Analyze enclosure atmosphere for hydrocarbons and record. This 
is the initial (time = 0 minutes) hydrocarbon concentration, 
CHCi, required in Sec.86.143. Hydrocarbon emissions may be 
sampled continuously during the test period.
    (B) Analyze the enclosure atmosphere for methanol, if applicable, 
and record. The methanol sampling must start simultaneously with the 
initiation of the hydrocarbon analysis and continue for 4.00.5 minutes. This is the initial (time = 0 minutes) 
methanol concentration, CCH3OHi, required in Sec.
86.143. Record the time elapsed during this analysis. If the 4-minute 
sample period is inadequate to collect a sample of sufficient 
concentration to allow accurate GC analysis, rapidly collect the 
methanol sample in a bag and then bubble the bag sample through the 
impingers at the specified flow rate. The time elapsed between 
collection of the bag sample and flow through the impingers should be 
minimized to prevent any losses.
    (xiii) Start the engine and begin operation of the vehicle over the 
drive cycle specified in paragraph (b) of this section.
    (xiv) The ambient temperature shall be maintained at 955 [deg]F (952 [deg]F on average) 
during the running loss test, measured at the inlet to the cooling fan 
in front of the vehicle; it shall be recorded at least every 60 seconds.
    (xv) The fuel temperature during the dynamometer drive shall be 
controlled to match the fuel tank temperature profile determined in 
Sec.86.129. Measured fuel temperatures must be within 3 [deg]F

[[Page 703]]

of the target profile throughout the test run. Vapor temperatures, if 
measured, must be within 5 [deg]F of the target 
profile during the first 4186 seconds of the running loss test, and 
within 3 [deg]F for the remaining 120 seconds of 
the test run. For any vehicle complying with the test standards, vapor 
temperatures may be higher than the specified tolerances without 
invalidating test results. For testing by the Administrator, vapor 
temperatures may be lower than the specified tolerances without 
invalidating test results. If the test vehicle has more than one fuel 
tank, the temperatures for both fuel tanks shall follow the target 
profiles determined in Sec.86.129. The control system shall be tuned 
and operated to provide smooth and continuous tank temperature profiles 
that are representative of the on-road profiles.
    (xvi) Fuel tank pressure must not exceed 10 inches of water during 
the running loss test, except that temporary exceedances are allowed for 
vehicles whose tank pressure remained below 10 inches of water during 
the entire outdoor driving period specified in Sec.86.129. These 
temporary pressure exceedances may not occur for more than 10 percent of 
the total driving time.
    (xvii) The FID (or HFID) hydrocarbon analyzer shall be zeroed and 
spanned immediately prior the end of the test.
    (xviii) Fresh impingers shall be installed in the methanol 
collection system immediately prior to the end of the test, if 
applicable.
    (xix) The running loss test ends with the completion of the third 2-
minute idle period.
    (xx) At the end of the running loss test:
    (A) Analyze the enclosure atmosphere for hydrocarbons and record. 
This is the final hydrocarbon concentration, CHCf, required 
in Sec.86.143.
    (B) Analyze the enclosure atmosphere for methanol, if applicable, 
and record. The methanol sampling must start prior to the end of the 
test and continue for 4.00.5 minutes. The methanol 
sampling must be completed within 2 minutes after the end of the running 
loss test. This is the final methanol concentration, 
CCH3OHf, required in Sec.86.143. Record the time 
elapsed during this analysis. If the 4-minute sample period is 
inadequate to collect a sample of sufficient concentration to allow 
accurate GC analysis, rapidly collect the methanol sample in a bag and 
then bubble the bag sample through the impingers at the specified flow 
rate. The time elapsed between collection of the bag sample and flow 
through the impingers should be minimized to prevent any losses.
    (C) Turn off all the fans specified in Sec.86.107-96(d). Also, the 
time that the vehicle's engine compartment cover is open for removal of 
air intake equipment, if applicable, shall be minimized to avoid loss of 
heat from the engine compartment.
    (xxi) Turn off any CVS apparatus (if not already turned off).
    (2) Point-source method. (i) The test vehicle, with the engine off, 
shall be moved onto the dynamometer. The vehicle engine compartment 
cover and any windows, doors, and luggage compartments shall be closed.
    (ii) Fans shall be positioned as described in Sec. Sec.86.135-
90(b) and 86.107-96(d).
    (iii) The running loss vapor vent collection system shall be 
properly positioned at the potential fuel vapor vents or leaks of the 
vehicle's fuel system. Typical vapor vents for current fuel systems are 
the ports of the evaporative emission canister and the pressure relief 
vent of the fuel tank (typically integrated into the fuel tank cap).
    (iv) The running loss vapor vent collection system may be connected 
to a PDP-CVS or CFV-CVS bag collection system. Otherwise, running loss 
vapors shall be sampled continuously with analyzers meeting the 
requirements of Sec.86.107-96(b).
    (v) Fans shall be positioned as described in Sec.86.107-96(d).
    (vi) Set vehicle air conditioning controls as described in 40 CFR 
1066.835.
    (vii) The temperature and pressure recording systems shall be 
started. Measurement of vapor temperature is optional during the running 
loss test. If vapor temperature is not measured, fuel tank pressure need 
not be measured.
    (viii) The temperature of the liquid fuel shall be monitored and 
recorded at

[[Page 704]]

least every 15 seconds with the temperature recording system specified 
in Sec.86.107-96(e).
    (ix) When the ambient temperature is 955 
[deg]F (353 [deg]C) and the fuel tank temperature 
is 953 [deg]F the running loss test may begin.
    (x) The ambient temperature shall be maintained at 955 [deg]F (952 [deg]F on average) 
during the running loss test, measured at the inlet to the cooling fan 
in front of the vehicle; it shall be recorded at least every 60 seconds.
    (xi) Fuel temperatures shall be controlled according to the 
specifications of paragraph (g)(1)(xv) of this section.
    (xii) The tank pressure requirements described in paragraph 
(g)(1)(xvi) of this section apply also to running loss testing by the 
point source method.
    (xiii) The running loss test ends with completion of the third 2-
minute idle period.
    (xiv) If emissions are collected in bags, the sample bags must be 
analyzed within 20 minutes of their respective sample collection phases, 
as described in Sec.86.137-94(b)(15). The results of the analysis are 
used in Sec.86.143 to calculate the mass of hydrocarbons emitted.
    (xv) At the end of the running loss test, turn off all the fans 
specified in Sec.86.107-96(d).
    (3) With prior approval of the Administrator, manufacturers may use 
an alternative running loss test procedure, provided the alternative 
test procedure is shown to yield equivalent or superior emission results 
(in terms of quality control, accuracy and repeatability) for the 
running loss, hot soak and diurnal portions of the three diurnal-plus-
hot-soak test sequence. Additionally, the Administrator may conduct 
certification and in-use testing using the test procedures outlined in 
paragraph (g)(1) of this section, paragraph (g)(2) of this section or 
the alternative running loss test procedure as approved for a specific 
vehicle.
    (4) High-altitude testing. For testing under high-altitude 
conditions, decrease the target ambient and fuel temperatures by 5 
[deg]F. For example, the fuel temperature profile should be adjusted 
downward based on a nominal starting temperature of 90 [deg]F, and the 
nominal temperature in the enclosure should be 90 [deg]F.
    (h) Following the completion of the running loss drive, the vehicle 
may be tested for hot soak emissions as specified in Sec.86.138-96.

Sec.86.135-12  Dynamometer procedure.

    (a) Overview. The dynamometer run consists of two tests, a ``cold'' 
start test, after a minimum 12-hour and a maximum 36-hour soak according 
to the provisions of Sec. Sec.86.132 and 86.133, and a ``hot'' start 
test following the ``cold'' start by 10 minutes. Engine startup (with 
all accessories turned off), operation over the UDDS, and engine 
shutdown make a complete cold start test. Engine startup and operation 
over the first 505 seconds of the driving schedule complete the hot 
start test. The exhaust emissions are diluted with ambient air in the 
dilution tunnel as shown in Figure B94-5 and Figure B94-6. A dilution 
tunnel is not required for testing vehicles waived from the requirement 
to measure particulates. Six particulate samples are collected on 
filters for weighing; the first sample plus backup is collected during 
the first 505 seconds of the cold start test; the second sample plus 
backup is collected during the remainder of the cold start test 
(including shutdown); the third sample plus backup is collected during 
the hot start test. Continuous proportional samples of gaseous emissions 
are collected for analysis during each test phase. For gasoline-fueled, 
natural gas-fueled and liquefied petroleum gas-fueled Otto-cycle 
vehicles, the composite samples collected in bags are analyzed for THC, 
CO, CO2, CH4, NOX, and N2O. 
For petroleum-fueled diesel-cycle vehicles (optional for natural gas-
fueled, liquefied petroleum gas-fueled and methanol-fueled diesel-cycle 
vehicles), THC is sampled and analyzed continuously according to the 
provisions of Sec.86.110-94. Parallel samples of the dilution air are 
similarly analyzed for THC, CO, CO2, CH4, 
NOX, and N2O. For natural gas-fueled, liquefied 
petroleum gas-fueled and methanol-fueled vehicles, bag samples are 
collected and analyzed for THC (if not sampled continuously), CO, 
CO2, CH4, NOX, and N2O.

[[Page 705]]

For methanol-fueled vehicles, methanol and formaldehyde samples are 
taken for both exhaust emissions and dilution air (a single dilution air 
formaldehyde sample, covering the total test period may be collected). 
For ethanol-fueled vehicles, methanol, ethanol, acetaldehyde, and 
formaldehyde samples are taken for both exhaust emissions and dilution 
air (a single dilution air formaldehyde sample, covering the total test 
period may be collected). Parallel bag samples of dilution air are 
analyzed for THC, CO, CO2, CH4, NOX, 
and N2O.
    (b) During dynamometer operation, a fixed speed cooling fan shall be 
positioned so as to direct cooling air to the vehicle in an appropriate 
manner with the engine compartment cover open. In the case of vehicles 
with front engine compartments, the fan shall be squarely positioned 
within 12 inches (30.5 centimeters) of the vehicle. In the case of 
vehicles with rear engine compartments (or if special designs make the 
above impractical), the cooling fan shall be placed in a position to 
provide sufficient air to maintain vehicle cooling. The fan capacity 
shall normally not exceed 5300 cfm (2.50 m\3\/sec). However, if the 
manufacturer can show that during field operation the vehicle receives 
additional cooling, and that such additional cooling is needed to 
provide a representative test, the fan capacity may be increased, 
additional fans used, variable speed fan(s) may be used, and/or the 
engine compartment cover may be closed, if approved in advance by the 
Administrator. For example, the hood may be closed to provide adequate 
air flow to an intercooler through a factory installed hood scoop. 
Additionally, the Administrator may conduct certification, fuel economy 
and in-use testing using the additional cooling set-up approved for a 
specific vehicle.
    (c) The vehicle speed as measured from the dynamometer rolls shall 
be used. A speed vs. time recording, as evidence of dynamometer test 
validity, shall be supplied on request of the Administrator.
    (d) Practice runs over the prescribed driving schedule may be 
performed at test point, provided an emission sample is not taken, for 
the purpose of finding the appropriate throttle action to maintain the 
proper speed-time relationship, or to permit sampling system adjustment. 
Both smoothing of speed variations and excessive accelerator pedal 
perturbations are to be avoided. When using two-roll dynamometers a 
truer speed-time trace may be obtained by minimizing the rocking of the 
vehicle in the rolls; the rocking of the vehicle changes the tire 
rolling radius on each roll. This rocking may be minimized by 
restraining the vehicle horizontally (or nearly so) by using a cable and 
winch.
    (e) The drive wheel tires may be inflated up to a gauge pressure of 
45 psi (310 kPa) in order to prevent tire damage. The drive wheel tire 
pressure shall be reported with the test results.
    (f) If the dynamometer has not been operated during the 2-hour 
period immediately preceding the test, it shall be warmed up for 15 
minutes by operating at 30 mph (48 kph) using a non-test vehicle or as 
recommended by the dynamometer manufacturer.
    (g) If the dynamometer horsepower must be adjusted manually, it 
shall be set within 1 hour prior to the exhaust emissions test phase. 
The test vehicle shall not be used to make this adjustment. Dynamometers 
using automatic control of pre-selectable power settings may be set 
anytime prior to the beginning of the emissions test.
    (h) The driving distance, as measured by counting the number of 
dynamometer roll or shaft revolutions, shall be determined for the 
transient cold start, stabilized cold start, and transient hot start 
phases of the test. The revolutions shall be measured on the same roll 
or shaft used for measuring the vehicle's speed.
    (i) Four-wheel drive and all-wheel drive vehicles may be tested 
either in a four-wheel drive or a two-wheel drive mode of operation. In 
order to test in the two-wheel drive mode, four-wheel drive and all-
wheel drive vehicles may have one set of drive wheels disengaged; four-
wheel and all-wheel drive vehicles which can be shifted to a two-wheel 
mode by the driver may be tested in a two-wheel drive mode of operation.

Sec.86.135-90  Dynamometer procedure.

    (a) The dynamometer run consists of two tests--a ``cold'' start 
test, after a minimum 12-hour and a maximum 36-hour soak according to 
the provisions of Sec. Sec.86.132 and 86.133, and a ``hot'' start test 
following the ``cold'' start by 10 minutes. Engine startup (with all 
accessories turned off), operation over the UDDS and engine shutdown 
make a complete cold-start test. Engine startup and operation over the 
first 505 seconds of the driving schedule complete the hot start test. 
The exhaust emissions are diluted with ambient air in the dilution 
tunnel as shown in Figure B94-5 and Figure B94-6. A dilution tunnel is 
not required for testing vehicles waived from the requirement to measure 
particulate matter. Six particulate samples are collected on filters for 
weighing; the first sample plus backup is collected during the first 505 
seconds of the cold-start test; the second sample plus backup is 
collected during the remainder of the cold-start test (including 
shutdown); the third sample plus backup is collected during the hot 
start test. Continuous or batch proportional samples of gaseous 
emissions are collected for analysis during each test phase. Use the 
following measurement procedures for each type of engine:
    (1) For gasoline-fueled, natural gas-fueled and liquefied petroleum 
gas-fueled Otto-cycle vehicles, the composite samples collected in bags 
are analyzed for THC, CO, CO2, CH4, and 
NOX.
    (2) For petroleum-fueled diesel-cycle vehicles (optional for natural 
gas-fueled, liquefied petroleum gas-fueled and methanol-fueled diesel-
cycle vehicles), THC is sampled and analyzed continuously according to 
the provisions of Sec.86.110. Parallel samples of the dilution air are 
similarly analyzed for THC, CO, CO2, CH4, and 
NOX.
    (3) For natural gas-fueled, liquefied petroleum gas-fueled and 
methanol-fueled vehicles, bag samples are collected and analyzed for THC 
(if not sampled continuously), CO, CO2, CH4, and 
NOX.
    (4) For methanol-fueled vehicles, methanol and formaldehyde samples 
are taken for both exhaust emissions and dilution air (a single dilution 
air formaldehyde sample, covering the total test period may be 
collected). Parallel bag samples of dilution air are analyzed for THC, 
CO, CO2, CH4, and NOX.
    (b) During dynamometer operation, a fixed speed cooling fan shall be 
positioned so as to direct cooling air to the vehicle in an appropriate 
manner with the engine compartment cover open. In the case of vehicles 
with front engine compartments, the fan shall be squarely positioned 
within 12 inches (30.5 centimeters) of the vehicle. In the case of 
vehicles with rear engine compartments (or if special designs make the 
above impractical), the cooling fan shall be placed in a position to 
provide sufficient air to maintain vehicle cooling. The fan capacity 
shall normally not exceed 5300 cfm (2.50 m3/sec). If however, the 
manufacturer can show that during field operation the vehicle receives 
additional cooling, and that such additional cooling is needed to 
provide a representative test, the fan capacity may be increased, 
additional fans used, variable speed fan(s) may be used, and/or the 
engine compartment cover may be closed if approved in advance by the 
Administrator. For example, the hood may be closed to provide adequate 
air flow to an intercooler through a factory installed hood scoop. 
Additionally, the Administrator may conduct certification, fuel economy 
and in-use testing using the additional cooling set-up approved for a 
specific vehicle.
    (c) The vehicle speed as measured from the dynamometer rolls shall 
be used. A speed vs. time recording, as evidence of dynamometer test 
validity, shall be supplied on request of the Administrator.
    (d) Practice runs over the prescribed driving schedule may be 
performed at test point, provided an emission sample is not taken, for 
the purpose of finding the appropriate throttle action to maintain the 
proper speed-time relationship, or to permit sampling system adjustment. 
Both smoothing of speed variations and excessive accelerator pedal 
perturbations are to be avoided. When using two-roll dynamometers a 
truer speed-time trace may be obtained by minimizing the rocking of the 
vehicle in the rolls; the rocking of the vehicle changes the tire 
rolling radius on

[[Page 707]]

each roll. This rocking may be minimized by restraining the vehicle 
horizontally (or nearly so) by using a cable and winch.
    (e) The drive wheel tires may be inflated up to a gauge pressure of 
45 psi (310 kPa) in order to prevent tire damage. The drive wheel tire 
pressure shall be reported with the test results.
    (f) lf the dynamometer has not been operated during the 2-hour 
period immediately preceding the test, it shall be warmed up for 15 
minutes by operating at 30 mph (48 kph) using a non-test vehicle or as 
recommended by the dynamometer manufacturer.
    (g) If the dynamometer horsepower must be adjusted manually, it 
shall be set within 1 hour prior to the exhaust emissions test phase. 
The test vehicle shall not be used to make this adjustment. Dynamometers 
using automatic control of preselectable power settings may be set 
anytime prior to the beginning of the emissions test.
    (h) The driving distance, as measured by counting the number of 
dynamometer roll or shaft revolutions, shall be determined for the 
transient cold start, stabilized cold start, and transient hot start 
phases of the test. The revolutions shall be measured on the same roll 
or shaft used for measuring the vehicle's speed.
    (i) Four-wheel drive and all-wheel drive vehicles may be tested 
either in a four-wheel drive or a two-wheel drive mode of operation. In 
order to test in the two-wheel drive mode, four-wheel drive and all-
wheel drive vehicles may have one set of drive wheels disengaged; four-
wheel and all-wheel drive vehicles which can be shifted to a two-wheel 
mode by the driver may be tested in a two-wheel drive mode of operation.

Sec.86.136-90  Engine starting and restarting.

    (a) Otto-cycle vehicles. Paragraph (a) of this section applies to 
Otto-cycle vehicles.
    (1) The engine shall be started according to the manufacturer's 
recommended starting procedures in the owner's manual. The initial 20-
second idle period shall begin when the engine starts.
    (2) Choke operation: (i) Vehicles equipped with automatic chokes 
shall be operated according to the manufacturer's operating instructions 
in the owner's manual, including choke setting and ``kick-down'' from 
cold fast idle.
    (ii) Vehicles equipped with manual chokes shall be operated 
according to the manufacturer's operating instructions in the owner's 
manual.
    (3) The transmission shall be placed in gear 15 seconds after the 
engine is started. If necessary, braking may be employed to keep the 
drive wheels from turning.
    (4) The operator may use the choke, accelerator pedal, etc., where 
necessary to keep the engine running.
    (5) If the manufacturer's operating instructions in the owner's 
manual do not specify a warm engine starting procedure, the engine 
(automatic and manual-choke engines) shall be started by depressing the 
accelerator pedal about half way and cranking the engine until it 
starts.
    (b) Diesel vehicles. The engine shall be started according to the 
manufacturers recommended starting procedures in the owners manual. The 
initial 20-second idle period shall begin when the engine starts. The 
transmission shall be placed in gear 15 seconds after the engine is 
started. If necessary, braking may be employed to keep the drive wheels 
from turning.
    (c) If the vehicle does not start after the manufacturer's 
recommended cranking time (or 10 continuous seconds in the absence of a 
manufacturer's recommendation), cranking shall cease for the period 
recommended by the manufacturer (or 10 seconds in the absence of a 
manufacturer's recommendation). This may be repeated for up to three 
start attempts. If the vehicle does not start after three attempts, the 
reason for failure to start shall be determined. The gas flow measuring 
device on the constant volume sampler (usually a revolution counter) or 
CFV (and the hydrocarbon integrator and particulate sampling system when 
testing petroleum-fueled diesel vehicles and the particulate

[[Page 708]]

sampling system when testing methanol-fueled diesel vehicles, see Sec.
86.137) shall be turned off and the sampler selector valves, including 
the methanol sampler, placed in the ``standby'' position during this 
diagnostic period. In addition, either the CVS should be turned off, or 
the exhaust tube disconnected from the tailpipe during the diagnostic 
period. If failure to start is an operational error, the vehicle shall 
be rescheduled for testing from a cold start.
    (d) If the engine ``false starts'' the operator shall repeat the 
recommended starting procedure (such as resetting the choke, etc.).
    (e) Stalling. (1) If the engine stalls during an idle period, the 
engine shall be restarted immediately and the test continued. If the 
engine cannot be started soon enough to allow the vehicle to follow the 
next acceleration as prescribed, the driving schedule indicator shall be 
stopped. When the vehicle restarts, the driving schedule indicator shall 
be reactivated.
    (2) If the engine stalls during some operating mode other than idle, 
the driving schedule indicator shall be stopped, the vehicle shall then 
be restarted and accelerated to the speed required at that point in the 
driving schedule and the test continued. During acceleration to this 
point, shifting shall be performed in accordance with Sec.86.128.
    (3) If the vehicle will not restart within one minute, the test 
shall be voided, the vehicle removed from the dynamometer, corrective 
action taken, and the vehicle rescheduled for test. The reason for the 
malfunction (if determined) and the corrective action taken shall be 
reported to the Administrator.

Sec.86.137-94  Dynamometer test run, gaseous and particulate emissions.

    Section 86.137-94 includes text that specifies requirements that 
differ from Sec.86.137-90. Where a paragraph in Sec.86.137-90 is 
identical and applicable to Sec.86.137-94, this may be indicated by 
specifying the corresponding paragraph and the statement ``[Reserved]. 
For guidance see Sec.86.137-90.'' Where a corresponding paragraph of 
Sec.86.137-90 is not applicable, this is indicated by the statement 
``[Reserved].''
    (a) General. The dynamometer run consists of two tests, a cold start 
test, after a minimum 12-hour and a maximum 36-hour soak according to 
the provisions of Sec.86.132, and a hot start test following the cold 
start test by 10 minutes. The vehicle shall be stored prior to the 
emission test in such a manner that precipitation (e.g., rain or dew) 
does not occur on the vehicle. The complete dynamometer test consists of 
a cold start drive of 7.5 miles (12.1 km) and simulates a hot start 
drive of 7.5 miles (12.1 km). The vehicle is allowed to stand on the 
dynamometer during the 10 minute time period between the cold and hot 
start tests. The cold start test is divided into two periods. The first 
period, representing the cold start ``transient'' phase, terminates at 
the end of the deceleration which is scheduled to occur at 505 seconds 
of the driving schedule. The second period, representing the 
``stabilized'' phase, consists of the remainder of the driving schedule 
including engine shutdown. The hot start test, similarly, consists of 
two periods. The first period, representing the hot start ``transient'' 
phase, terminates at the same point in driving schedule as the first 
period of the cold start test. The second period of the hot start test, 
``stabilized'' phase, is assumed to be identical to the second period of 
the cold start test. Therefore, the hot start test terminates after the 
first period (505 seconds) is run.
    (b) The following steps shall be taken for each test:
    (1) Place drive wheels of vehicle on dynamometer without starting 
engine.
    (2) Open the vehicle engine compartment cover and position the 
cooling fan.
    (3) For all vehicles, with the sample selector valves in the 
``standby'' position, connect evacuated sample collection bags to the 
dilute exhaust and dilution air sample collection systems.
    (4) For methanol-fueled vehicles, with the sample selector valves in 
the ``standby'' position, insert fresh sample collection impingers into 
the methanol sample collection system, fresh

[[Page 709]]

impingers or a fresh cartridge into the formaldehyde sample collection 
system and fresh impingers (or a single cartridge for formaldehyde) into 
the dilution air sample collection systems for methanol and formaldehyde 
(background measurements of methanol and formaldehyde may be omitted and 
concentrations assumed to be zero for calculations in Sec.86.144).
    (5) Start the CVS (if not already on), the sample pumps (except the 
particulate sample pump, if applicable), the temperature recorder, the 
vehicle cooling fan, and the heated THC analysis recorder (diesel-cycle 
only). (The heat exchanger of the constant volume sampler, if used, 
petroleum-fueled diesel-cycle THC analyzer continuous sample line and 
filter, methanol-fueled vehicle THC, methanol and formaldehyde sample 
lines, if applicable, should be preheated to their respective operating 
temperatures before the test begins).
    (6) Adjust the sample flow rates to the desired flow rate and set 
the gas flow measuring devices to zero.
    (i) For gaseous bag samples (except THC samples), the minimum flow 
rate is 0.17 cfm (0.08 1/sec).
    (ii) For THC samples, the minimum FID (or HFID in the case of 
diesel-cycle and methanol-fueled Otto-cycle vehicles) flow rate is 0.066 
cfm (0.031 1/sec).
    (iii) For methanol samples, the flow rates shall be set such that 
the system meets the design criteria of Sec.86.109 and Sec.86.110. 
For samples in which the concentration in the primary impinger exceeds 
0.5 mg/l, it is recommended that the mass of methanol collected in the 
secondary impinger not exceed ten percent of the total mass collected. 
For samples in which the concentration in the primary impinger does not 
exceed 0.5 mg/l, analysis of the secondary impingers is not necessary.
    (iv) For formaldehyde samples, the flow rates shall be set such that 
the system meets the design criteria of Sec.86.109 and Sec.86.110. 
For impinger samples in which the concentration of formaldehyde in the 
primary impinger exceeds 0.1 mg/l, it is recommended that the mass of 
formaldehyde collected in the secondary impinger not exceed ten percent 
of the total mass collected. For samples in which the concentration in 
the primary impinger does not exceed 0.1 mg/l, analysis of the secondary 
impingers is not necessary.
    (7) Attach the exhaust tube to the vehicle tailpipe(s).
    (8) Carefully install a particulate sample filter into each of the 
filter holders. The filters must be handled only with forceps or tongs. 
Rough or abrasive filter handling will result in erroneous weight 
determination.
    (9) Start the gas flow measuring device, position the sample 
selector valves to direct the sample flow into the ``transient'' exhaust 
sample bag, the ``transient'' methanol exhaust sample, the ``transient'' 
formaldehyde exhaust sample, the ``transient'' dilution air sample bag, 
the ``transient'' methanol dilution air sample and the ``transient'' 
formaldehyde dilution air sample (turn on the petroleum-fueled diesel-
cycle THC analyzer system integrator, mark the recorder chart, start 
particulate sample pump No. 1, and record both gas meter or flow 
measurement instrument readings, if applicable), turn the key on, and 
start cranking the engine.
    (10) Fifteen seconds after the engine starts, place the transmission 
in gear.
    (11) Twenty seconds after the engine starts, begin the initial 
vehicle acceleration of the driving schedule.
    (12) Operate the vehicle according to the Urban Dynamometer Driving 
Schedule (Sec.86.115).

    Note: During particulate testing, adjust the flow rate through the 
particulate sample probe to maintain a constant value within 5 percent of the set flow rate. Record the average 
temperature and pressure at the gas meter or flow instrument inlet. If 
the set flow rate cannot be maintained because of high particulate 
loading on the filter, the test shall be terminated. The test shall be 
rerun using a lower flow rate, or larger diameter filter, or both.

    (13) At the end of the deceleration which is scheduled to occur at 
505 seconds, simultaneously switch the sample flows from the 
``transient'' bags and samples to the ``stabilized'' bags and samples, 
switch off gas flow measuring device No. 1, switch off the No. 1 
petroleum-fueled diesel hydrocarbon integrator and the No. 1 particulate 
sample pump, mark the petroleum-fueled diesel hydrocarbon recorder

[[Page 710]]

chart, and close valves isolating particulate filter No. 1, if 
applicable, start gas flow measuring device No. 2, and start the 
petroleum-fueled diesel hydrocarbon integrator No. 2 and the No. 2 
particulate sample pump and open valves isolating particulate filter No. 
2, if applicable. Before the acceleration which is scheduled to occur at 
510 seconds, record the measured roll or shaft revolutions and reset the 
counter or switch to a second counter. As soon as possible transfer the 
``transient'' exhaust and dilution air samples to the analytical system 
and process the samples according to Sec.86.140 obtaining a stabilized 
reading of the bag exhaust sample on all analyzers within 20 minutes of 
the end of the sample collection phase of the test. Obtain methanol and 
formaldehyde sample analyses, if applicable, within 24 hours of the end 
of the sample collection phase of the test.
    (14) Turn the engine off 2 seconds after the end of the last 
deceleration (at 1,369 seconds).
    (15) Five seconds after the engine stops running, simultaneously 
turn off gas flow measuring device No. 2 and if applicable, turn off the 
hydrocarbon integrator No. 2, mark the hydrocarbon recorder chart, turn 
off the No. 2 particulate sample pump and close the valves isolating 
particulate filter No. 2, and position the sample selector valves to the 
``standby'' position (and open the valves isolating particulate filter 
No. 1, if applicable). Record the measured roll or shaft revolutions 
(both gas meter or flow measurement instrumentation readings), and reset 
the counter. As soon as possible, transfer the ``stabilized'' exhaust 
and dilution air samples to the analytical system and process the 
samples according to Sec.86.140, obtaining a stabilized reading of the 
exhaust bag sample on all analyzers within 20 minutes of the end of the 
sample collection phase of the test. Obtain methanol and formaldehyde 
sample analyses, if applicable, within 24 hours of the end of the sample 
period. (If it is not possible to perform analysis on the methanol and 
formaldehyde samples within 24 hours, the samples should be stored in a 
dark cold (4-10 [deg]C) environment until analysis. The samples should 
be analyzed within fourteen days.) If applicable, carefully remove both 
pairs of particulate sample filters from their respective holders, and 
place each in a separate petri dish, and cover.
    (16) Immediately after the end of the sample period, turn off the 
cooling fan and close the engine compartment cover.
    (17) Turn off the CVS or disconnect the exhaust tube from the 
tailpipe(s) of the vehicle.
    (18) Repeat the steps in paragraphs (b)(2) through (b)(12) of this 
section for the hot start test, except only two evacuated sample bags, 
two methanol sample impingers, two formaldehyde sample impingers, and 
one pair of particulate sample filters, as appropriate, are required. 
The step in paragraph (b)(9) of this section shall begin between 9 and 
11 minutes after the end of the sample period for the cold-start test.
    (19) At the end of the deceleration scheduled to occur at 505 
seconds, simultaneously turn off gas flow measuring device No. 1 (and 
the petroleum-fueled diesel hydrocarbon integrator No. 1; mark the 
petroleum-fueled diesel hydrocarbon recorder chart and turn off the No. 
1 particulate sample pump, if applicable) and position the sample 
selector valve to the ``standby'' position. (Engine shutdown is not part 
of the hot start test sample period.) Record the measured roll or shaft 
revolutions (and the No. 1 gas meter reading or flow measurement 
instrument). Carefully remove the third pair of particulate sample 
filters from the holder and place in a clean petri dish and cover, if 
applicable.
    (20) As soon as possible, transfer the hot start ``transient'' 
exhaust and dilution air samples to the analytical system and process 
the samples according to Sec.86.140, obtaining a stabilized reading of 
the exhaust bag sample on all analyzers within 20 minutes of the end of 
the sample collection phase of the test. Obtain methanol and 
formaldehyde sample analyses, if applicable, within 24 hours of the end 
of the sample period. If it is not possible to perform analysis on the 
methanol and formaldehyde samples within 24 hours, the samples should be 
stored in a dark,

[[Page 711]]

cold (4-10 [deg]C) environment until analysis. Analyze the samples 
within fourteen days.
    (21) As soon as possible, and in no case longer than one hour after 
the end of the hot start phase of the test, transfer the six particulate 
filters to the weighing chamber for post-test conditioning, if 
applicable.
    (22) Disconnect the exhaust tube from the vehicle tailpipe(s) and 
drive the vehicle from dynamometer.
    (23) The CVS or CFV may be turned off, if desired.
    (24) Vehicles to be tested for evaporative emissions proceed 
according to Sec.86.134; vehicles to be tested with the supplemental 
two-diurnal test sequence for evaporative emissions proceed according to 
Sec.86.138-96(k). For all others, this completes the test sequence.

Sec.86.138-96  Hot soak test.

    (a)(1) Gasoline- and methanol-fueled vehicles. For gasoline- and 
methanol-fueled vehicles, the hot soak test shall be conducted 
immediately following the running loss test. However, sampling of 
emissions from the running loss test is not required as preparation for 
the hot soak test.
    (2) Gaseous-fueled vehicles. Since gaseous-fueled vehicles are not 
required to perform a running loss test, the hot soak test shall be 
conducted within seven minutes after completion of the hot start exhaust 
test.
    (b) The hot soak test may be conducted in the running loss enclosure 
as a continuation of that test or in a separate enclosure.
    (1) If the hot soak test is conducted in the running loss enclosure, 
the driver may exit the enclosure after the running loss test. If 
exiting, the driver should use the personnel door described in Sec.
86.107-96(a)(2), exiting as quickly as possible with a minimum 
disturbance to the system. The final hydrocarbon and methanol 
concentration for the running loss test, measured in Sec.86.134-
96(g)(1)(xx), shall be the initial hydrocarbon and methanol 
concentration (time = 0 minutes) CHCi and 
CCH3OHi, for the hot soak test.
    (2) If the vehicle must be moved to a different enclosure, the 
following steps must be taken:
    (i) The enclosure for the hot soak test shall be purged for several 
minutes prior to completion of the running loss test. WARNING: If at any 
time the concentration of hydrocarbons, of methanol, or of methanol and 
hydrocarbons exceeds 15,000 ppm C the enclosure should be immediately 
purged. This concentration provides at least a 4:1 safety factor against 
the lean flammability limit.
    (ii) The FID hydrocarbon analyzer shall be zeroed and spanned 
immediately prior to the test.
    (iii) Fresh impingers shall be installed in the methanol sample 
collection system immediately prior to the start of the test, if 
applicable.
    (iv) If not already on, the mixing fan(s) shall be turned on at this 
time. Throughout the hot soak test, the mixing fan(s) shall circulate 
the air at a rate of 0.80.2 cfm per cubic foot of 
the nominal enclosure volume.
    (v) Begin sampling as follows:
    (A) Analyze the enclosure atmosphere for hydrocarbons and record. 
This is the initial (time = 0 minutes) hydrocarbon concentration, 
CHCi, required in Sec.86.143. Hydrocarbon emissions may be 
sampled continuously during the test period.
    (B) Analyze the enclosure atmosphere for methanol, if applicable, 
and record. The methanol sampling must start simultaneously with the 
initiation of the hydrocarbon analysis and continue for 4.00.5 minutes. This is the initial (time = 0 minutes) 
methanol concentration, CCH3OHi, required in Sec.
86.143. Record the time elapsed during this analysis. If the 4-minute 
sample period is inadequate to collect a sample of sufficient 
concentration to allow accurate GC analysis, rapidly collect the 
methanol sample in a bag and then bubble the bag sample through the 
impingers at the specified flow rate. The time elapsed between 
collection of the bag sample and flow through the impingers should be 
minimized to prevent any losses.
    (vi) The vehicle engine compartment cover shall be closed (if not 
already closed), the cooling fan shall be moved, the vehicle shall be 
disconnected from

[[Page 712]]

the dynamometer and any sampling system, and then driven at minimum 
throttle to the enclosure for the hot soak test. These steps should be 
done as quickly as possible to minimize the time needed to start the hot 
soak test.
    (vii) The vehicle's engine must be stopped before any part of the 
vehicle enters the enclosure.
    (viii) The vehicle shall enter the enclosure; the enclosure doors 
shall be closed and sealed within 2 minutes of engine shutdown and 
within seven minutes after the end of the running loss test.
    (ix) The test vehicle windows and any luggage compartments shall be 
opened (if not already open). The vehicle engine compartment cover shall 
be closed (if not already closed).
    (c) [Reserved]
    (d) The temperature recording system shall be started and the time 
of engine shutoff shall be noted on the evaporative emission hydrocarbon 
data recording system.
    (e) For the first 5 minutes of the hot soak test, the ambient 
temperature shall be maintained at 9510 [deg]F. 
For the remainder of the hot soak test, the ambient temperature shall be 
maintained at 955 [deg]F (952 [deg]F on average).
    (f) The 600.5 minute hot soak begins when the 
enclosure doors are sealed (or when the running loss test ends, if the 
hot soak test is conducted in the running loss enclosure).
    (g) The FID (or HFID) hydrocarbon analyzer shall be zeroed and 
spanned immediately prior to the end of the test.
    (h) Fresh impingers shall be installed in the methanol collection 
system immediately prior to the end of the test, if applicable.
    (i) [Reserved]
    (j) At the end of the 600.5 minute test 
period:
    (1) Analyze the enclosure atmosphere for hydrocarbons and record. 
This is the final (time = 60 minutes) hydrocarbon concentration, 
CHCf, required in Sec.86.143.
    (2) Analyze the enclosure atmosphere for methanol and record, if 
applicable. The methanol sampling must start simultaneously with the 
initiation of the hydrocarbon analysis and continue for 4.00.5 minutes. This is the final (time = 60 minutes) 
methanol concentration, CCH3OHf, required in Sec.
86.143. Record the time elapsed during this analysis. If the 4-minute 
sample period is inadequate to collect a sample of sufficient 
concentration to allow accurate GC analysis, rapidly collect the 
methanol sample in a bag and then bubble the bag sample through the 
impingers at the specified flow rate. The time elapsed between 
collection of the bag sample and flow through the impingers should be 
minimized to prevent any losses.
    (k) For the supplemental two-diurnal test sequence (see Sec.
86.130-96), perform a hot soak test as described in this section, except 
that the test shall be conducted within seven minutes after completion 
of the hot start exhaust test and temperatures throughout the hot soak 
measurement period must be between 68 [deg] and 86 [deg]F. This hot soak 
test is followed by two consecutive diurnal heat builds, described in 
Sec.86.133-96(p).
    (l) If the vehicle is to be tested for diurnal emissions, follow the 
procedure outlined in Sec.86.133-96.

Sec.86.139-90  Particulate filter handling and weighing.

    (a) At least 8 hours, but not more than 56 hours before the test, 
place each filter in an open, but protected, petri dish and place in the 
weighing chamber which meets the humidity and temperature specifications 
of Sec.86.112.
    (b) At the end of the 8 to 56 hour stabilization period, weigh the 
filter on a balance having a precision of one microgram. Record this 
weight. This reading is the tare weight.
    (c) The filter shall then be stored in a covered petri dish which 
shall remain in the weighing chamber until needed for testing.
    (d)(1) If the filter is not used within one hour of its removal from 
the weighing chamber, it shall be reweighed.
    (2) The one hour limit may be replaced by an eight-hour limit if one 
or both of the following conditions are met:

[[Page 713]]

    (i) A stabilized filter is placed and kept in a sealed filter holder 
assembly with the ends plugged, or
    (ii) A stabilized filter is placed in a sealed filter holder 
assembly, which is then immediately placed in a sample line through 
which there is no flow.
    (e) After the test, and after the sample filter is returned to the 
weighing room, condition it for at least 1 hour but not more than 56 
hours. Then weigh a second time. This latter reading is the gross weight 
of the filter. Record this weight.
    (f) The net weight (Pe) is the gross weight minus the 
tare weight.

    Note: Should the sample on the filter contact the petri dish or any 
other surface, the test is void and must be rerun.

[54 FR 14532, Apr. 11, 1989]



Sec.86.140-94  Exhaust sample analysis.

    The following sequence shall be performed in conjunction with each 
series of measurements:
    (a) For CO, CO2, CH4, NOX, and for 
Otto-cycle and methanol-fueled, natural gas-fueled and liquefied 
petroleum gas-fueled (if non-heated FID option is used) diesel vehicle 
HC:
    (1) Zero the analyzers and obtain a stable zero reading. Recheck 
after tests.
    (2) Introduce span gases and set instrument gains. In order to avoid 
errors, span and calibrate at the same flow rates used to analyze the 
test sample. Span gases should have concentrations equal to 75 to 100 
percent of full scale. If gain has shifted significantly on the 
analyzers, check the calibrations. Show actual concentrations on chart.
    (3) Check zeroes; repeat the procedure in paragraphs (a) (1) and (2) 
of this section if required.
    (4) Check flow rates and pressures.
    (5) Measure THC, CO, CO2, CH4, and 
NOX concentrations of samples.
    (6) Check zero and span points. If difference is greater than 2 
percent of full scale, repeat the procedure in paragraphs (a) (1) 
through (5) of this section.
    (b) For petroleum-fueled, natural gas-fueled and liquefied petroleum 
gas-fueled (if HFID is used) diesel vehicle HC:
    (1) Zero HFID analyzer and obtain a stable zero reading.
    (2) Introduce span gas and set instrument gains. Span gas should 
have concentration equal to 75 to 100 percent of full scale.
    (3) Check zero as in paragraph (b)(1) of this section.
    (4) Introduction of zero and span gas into the analyzer can be 
accomplished by either of the following methods:
    (i) Close heated valve in THC sample (see Figures B94-5 or B94-6) 
and allow gases to enter HFID. Extreme care should be taken not to 
introduce gases under high pressure.
    (ii) Connect zero and span line directly to THC sample probe and 
introduce gases at a flow rate greater than 125 percent of the HFID flow 
rate with the CVS blower operating (see Figures B94-5 or B94-6). Excess 
flow must be allowed to exit probe inlet.

    Note: In order to minimize errors, HFID flow rate and pressure 
during zero and span (and background bag reading) must be exactly the 
same as that used during testing.

    (5) Continuously record (integrate electronically if desired) dilute 
THC emission levels during test. Background samples are collected in 
sample bags and analyzed as in paragraphs (b)(4) (i) or (ii) of this 
section.
    (6) Check zero and span as in paragraphs (b) (1) through (4) of this 
section. If difference is greater than 2 percent of full scale, void 
test and check for THC ``hangup'' or electronic drift in analyzer.
    (c) For CH3OH (methanol-fueled vehicles), introduce test 
samples into the gas chromatograph and measure the concentration. This 
concentration is CMS in the calculations.
    (d) For HCHO (methanol-fueled vehicles), introduce formaldehyde test 
samples into the high pressure liquid chromatograph and measure the 
concentration of formaldehyde as a dinitrophenylhydrazine derivative in 
acetonitrile. This concentration is CFS in the calculations.
    (e) For CH4 analysis:
    (1) In the event that the procedure results in negative 
NMHCwm values (as may occur with high methane fractions), any 
negative NMHCwm value whose absolute value is less than 10 
percent of the NMHC standard shall be

[[Page 714]]

rounded to zero. Negative NMHCwm values whose absolute value 
is more than 10 percent of the NMHC standard shall require sample 
remeasurement. If the 10 percent criterion cannot be met after 
remeasurement, the test will be void.
    (2) Other sampling procedures may be used if shown to yield 
equivalent or superior results and if approved in advance by the 
Administrator.

Sec.86.145-82  Calculations; particulate emissions.

    (a) The final reported test results for the mass particulate 
(Mp) in grams/mile shall be computed as follows.

Mp = 0.43(Mp1 + Mp2)/(Dct + 
Ds) + 0.57(Mp3 + Mp2)/(Dht = 
Ds)

where:
    (1) Mp1 = Mass of particulate determined from the 
``transient'' phase of the cold start test, in grams per test phase. 
(See Sec.86.110-82(c)(1) for determination.)
    (2) Mp2 = Mass of particulate determined from the 
``stabilized'' phase of the cold start test, in grams per test phase. 
(See Sec.86.110-82(c)(1) for determination.)

Sec.86.110-82(c)(1) for determination).
    (4) Dct = The measured driving distance from the 
``transient'' phase of the cold start test, in miles.
    (5) Ds = The measured driving distance from the 
``stabilized'' phase of the cold start test, in miles.
    (6) Dht = The measured driving distance from the 
``transient'' phase of the hot start test, in miles.
    (b) The mass of particulate for each phase of testing is determined 
as follows:
[GRAPHIC] [TIFF OMITTED] TR06OC93.074


where:
    (1) j = 1, 2 or 3 depending on which phase the mass of particulate 
is being determined for (i.e., the ``transient'' phase of the cold start 
test, the ``stabilized'' phase of the cold start test, or the 
``transient'' phase of the hot start test).
    (2) Vmix = Total dilute exhaust volume in cubic meters 
per test, corrected to standard conditions 528[deg]R (293K) and 29.92 in 
Hg (101.3 kPa). Vmix is further defined in Sec.86.144.
    (3) Pe = mass of particulate per test on the exhaust 
filter(s), grams.
    (4) Pb = mass of particulate on the ``background'' 
filter, grams.
    (i) The background particulate level, Pb, inside the 
dilution air filter box at EPA is very low. Pb will be 
assumed = 0, and background particulate samples will not be taken with 
each exhaust sample. It is recommended that background particulate 
checks be made periodically to verify the low level.
    (ii) Any manufacturer may make the same assumption without prior EPA 
approval.
    (iii) If Pb is assumed = 0, then no background correction 
is made. The equation for particulate mass emissions then reduces to:

    (ii) Pbar = barometric pressure, in Hg.
    (iii) Pip = pressure elevation above ambient measured at 
the inlet to the dilute exhaust sample gas meter or flow instrument, in

sample at the inlet to the gas meter or flow instrument, [deg]R.
    (7) Vbp = total volume of the background sample, cubic

Sec.86.146-96  Fuel dispensing spitback procedure.

    (a) The vehicle is fueled at a rate of 10 gal/min to test for fuel 
spitback emissions. All liquid fuel spitback emissions that occur during 
the test are collected in a bag made of a material impermeable to 
hydrocarbons or methanol. The bag shall be designed and used so that 
liquid fuel does not spit back onto the vehicle body, adjacent floor, 
etc., and it must not impede the free flow of displaced gasoline vapor 
from the orifice of the filler pipe. The bag must be designed to permit 
passage of the dispensing nozzle through the bag. If the bag has been 
used for previous testing, sufficient time shall be allowed for the bag 
to dry out. The dispensing nozzle shall be a commercial model, not 
equipped with vapor recovery hardware.
    (b) Ambient temperature levels encountered by the test vehicle shall 
be not less than 68 [deg]F nor more than 86 [deg]F. The temperatures 
monitored during testing must be representative of those experienced by 
the test vehicle. The vehicle shall be approximately level during all 
phases of the test sequence to prevent abnormal fuel distribution.
    (c) Measure and record the mass of the bag to be used for collecting 
spitback emissions to the nearest 0.01 gram.
    (d) Drain the fuel tank(s) and fill with test fuel, as specified in 
Sec.86.113, to 10 percent of the reported nominal fuel tank capacity. 
The fuel cap(s) shall be installed immediately after refueling.
    (e) The vehicle shall be soaked at 806 [deg]F 
(273 [deg]C) for a minimum of six hours, then 
placed, either by being driven or pushed, on a dynamometer and operated 
through one Urban Dynamometer Driving Schedule (specified in Sec.
86.115 and appendix I of this part). The test vehicle may not be used to 
set dynamometer horsepower.
    (f) Following the preconditioning drive, the vehicle shall be moved 
or driven at minimum throttle to the refueling area.
    (g) All areas in proximity to the vehicle fuel fill orifice and the 
dispenser nozzle itself shall be completely dry of liquid fuel.
    (h) The fuel filler neck shall be snugly fitted with the vented bag 
to capture

[[Page 726]]

any fuel emissions. The fuel nozzle shall be inserted through the bag 
into the filler neck of the test vehicle to its maximum penetration. The 
plane of the nozzle's handle shall be perpendicular to the floor of the 
laboratory.
    (i) The fueling procedure consists of dispensing fuel through a 
nozzle, interrupted by a series of automatic shutoffs. A minimum of 3 
seconds shall elapse between any automatic shutoff and subsequent 
resumption of dispensing. Dispensing may not be manually terminated, 
unless the test vehicle has already clearly failed the test. The vehicle 
shall be fueled according to the following procedure:
    (1) The fueling operation shall be started within 4 minutes after 
the vehicle is turned off and within 8 minutes after completion of the 
preconditioning drive. The average temperature of the dispensed fuel 
shall be 65 5 [deg]F (18 3 
[deg]C).
    (2) The fuel shall be dispensed at a rate of 9.80.3 gallons/minute (37.11.1 L/min) 
until the automatic shutoff is activated.
    (3) If the automatic shutoff is activated before the nozzle has 
dispensed an amount of fuel equal to 70 percent of the tank's nominal 
capacity, the dispensing may be resumed at a reduced rate. Repeat as 
necessary until the nozzle has dispensed an amount of fuel equal to at 
least 70 percent of the tank's nominal capacity.
    (4) Once the automatic shutoff is activated after the nozzle has 
dispensed an amount of fuel equal to 70 percent of the tank's nominal 
capacity, the fuel shall be dispensed at a rate of 5 1 gallons/minute (19 4 [ell]/min) 
for all subsequent dispensing. Dispensing shall be restarted two 
additional times.
    (5) If the nozzle has dispensed an amount of fuel less than 85 
percent of the tank's nominal capacity after the two additional 
dispensing restarts, dispensing shall be resumed, and shall continue 
through as many automatic shutoffs as necessary to achieve this level. 
This completes the fueling procedure.
    (j) Withdraw the nozzle from the vehicle and the bag, holding the 
tip of the nozzle upward to avoid any dripping into the bag.
    (k) Within 1 minute after completion of the fueling event, the bag 
shall be folded to minimize the vapor volume inside the bag. The bag 
shall be folded as quickly as possible to prevent evaporation of 
collected emissions.
    (l) Within 5 minutes after completion of the fueling event, the mass 
of the bag and its contents shall be measured and recorded (consistent 
with paragraph (c) of this section). The bag shall be weighed as quickly 
as possible to prevent evaporation of collected emissions.

Sec.86.150-98  Refueling test procedure; overview.

    (a) The refueling emissions test procedure described in this and 
subsequent sections is used to determine the conformity of vehicles with 
the refueling emissions standards set forth in subpart A of this part 
for light-duty vehicles and light-duty trucks. The refueling emissions 
test procedure may be performed as an individual test or in combination 
with the evaporative and exhaust emissions test sequences of Sec.
86.130-96.
    (b) The refueling emissions test is designed to measure hydrocarbon 
emissions resulting from the generation or displacement of fuel tank 
vapor during vehicle refueling. The refueling emissions shall be 
measured by the enclosure technique.
    (c) All emission control systems installed on or incorporated in a 
new motor vehicle shall be functioning during all procedures in this 
subpart except:
    (1) In cases of component malfunction or failure; and
    (2) during certain specified fuel drain and fill operations, at 
which times the refueling emission control canister is disconnected. 
Maintenance to correct component malfunction or failure shall be 
authorized in accordance with Sec.86.098-25.
    (d) For liquefied petroleum gas-fueled vehicles only. Refueling test 
procedures for light-duty vehicles and light-duty trucks operated on 
liquefied petroleum gas are described in Sec.86.157.

Sec.86.151-98  General requirements; refueling test.

    (a) The refueling emissions procedure, shown in Figure B98-12, 
starts with the stabilizing of the vehicle and the loading of the 
refueling emissions canister(s) to breakthrough, and continues with the 
vehicle drive for purging of the canister, followed by the refueling 
emissions measurement. The test is conducted following Sec. Sec.
86.152-98 through 86.154-98 in order.
    (b) Ambient temperature levels encountered by the test vehicle 
throughout the test sequence shall not be less than 68 [deg]F (20 
[deg]C) nor more than 86 [deg]F (30 [deg]C).
    (c) The vehicle shall be approximately level during all phases of 
the test sequence to prevent abnormal fuel distribution.

Sec.86.152-98  Vehicle preparation; refueling test.

    (a) Provide additional fittings and adapters, as required, to 
accommodate a fuel drain at the lowest point possible in the tank(s) as 
installed on the vehicle. The canister shall not be removed from the 
vehicle, unless access to the canister in its normal location is so 
restricted that purging and loading can only reasonably be accomplished 
by removing the canister from the vehicle. Special care shall be taken 
during this step to avoid damage to the components and the integrity of 
the fuel system. A replacement canister may be temporarily installed 
during the soak period while the canister from the test vehicle is 
preconditioned.
    (b) Optionally, provide valving or other means to allow the venting 
of the refueling vapor line to the atmosphere rather than to the 
refueling emissions canister(s) when allowed by this test procedure.
    (c) For preconditioning that involves loading the vapor collection 
canister(s) with butane, provide valving or other means as necessary to 
allow loading of the canister(s).

FR 72927, Dec. 8, 2006]



Sec.86.153-98  Vehicle and canister preconditioning; refueling test.

    (a) Vehicle and canister preconditioning. Vehicles and vapor storage 
canisters shall be preconditioned in accordance with the preconditioning 
procedures for the supplemental two-diurnal evaporative emissions test 
specified in Sec.86.132-96 (a) through (j). For vehicles equipped with 
non-integrated refueling emission control systems, the canister must be 
loaded using the method involving butane loading to breakthrough (see 
Sec.86.132-96(j)(1)).
    (b) Seal test. The Administrator may choose to omit certain canister 
load and purge steps, and replace them with a bench purge of the 
refueling canister(s), in order to verify the adequacy of refueling 
emission control system seals. Failure of this seal test shall 
constitute a failure of the refueling emission control test. For 
integrated systems, this bench purge may be performed after the exhaust 
testing in order to obtain exhaust emission test results. Non-integrated 
system seal testing shall be performed using paragraph (b)(1) of this 
section.
    (1) Without the exhaust emission test. The Administrator may conduct 
the canister preconditioning by purging the canister(s) with at least 
1200 canister bed volumes of ambient air (with humidity controlled to 
5025 grains of water vapor per pound of dry air) 
maintained at a nominal flow rate of 0.8 cfm directly following the 
preconditioning drive described in Sec.86.132-96 (c) through (e). In 
this case, the canister loading procedures and the vehicle driving 
procedures described in Sec.86.132-96 (f) through (j) and in 
paragraphs (c) through (d) of this section shall be omitted, and the 10 
minute and 60 minute time requirements of paragraph (e) of this section 
shall apply to time after completion of the bench purge. In the case of 
multiple refueling canisters, each canister shall be purged separately.
    (2) With the exhaust emission test. The Administrator may conduct 
the canister preconditioning by purging the canister(s) directly after 
the exhaust test (see paragraph (c)(1) of this section). The canister 
shall be purged with at least 1200 canister bed volumes of ambient air 
(with humidity controlled to 5025 grains of water 
vapor per pound of dry air) maintained at a nominal flow rate of 0.8 
cfm. In this case, the vehicle driving procedures described in 
paragraphs (c)(2) through (d) of this section shall be omitted, and the 
10 minute and 60 minute time requirements of paragraph (e) of this 
section shall apply to time after completion of the bench purge. In the 
case of multiple refueling canisters, each canister shall be purged 
separately.
    (3) Manufacturers may use the procedures described in this paragraph 
(b) to demonstrate compliance with the seal test for vehicles with fuel 
tanks exceeding 35 gallons nominal fuel tank capacity, and for any 
incomplete vehicles.
    (c) Canister purging; integrated systems. (1) Vehicles to be tested 
for exhaust emissions only shall be processed according to Sec. Sec.
86.135-94 through 86.137-96. Vehicles to be tested for refueling

[[Page 729]]

emissions shall be processed in accordance with the procedures in 
Sec. Sec.86.135-94 through 86.137-96, followed by the procedures 
outlined in paragraph (c)(2) of this section.
    (2) To provide additional opportunity for canister purge, conduct 
additional driving on a dynamometer, within one hour of completion of 
the hot start exhaust test, by operating the test vehicle through one 
UDDS, a 2 minute idle, two NYCCs, another 2 minute idle, another UDDS, 
then another 2 minute idle (see Sec.86.115-78 and appendix I of this 
part). Fifteen seconds after the engine starts, place the transmission 
in gear. Twenty seconds after the engine starts, begin the initial 
vehicle acceleration of the driving schedule. The transmission shall be 
operated according to the specifications of Sec.86.128-79 during the 
driving cycles. The vehicle's air conditioner (if so equipped) shall be 
turned off. Ambient temperature shall be controlled as specified in 
Sec.86.151-98. It is not necessary to monitor and/or control in-tank 
fuel temperatures.
    (i) The fixed-speed fan specified in Sec.86.135-94(b) may be used 
for engine cooling. If a fixed-speed fan is used, the vehicle's hood 
shall be opened.
    (ii) Alternatively, the roadspeed-modulated fan specified in Sec.
86.107-96(d)(1) may be used for engine cooling. If a road-speed 
modulated fan is used, the vehicle's hood shall be closed.
    (d) Canister purging: non-integrated systems. Within one hour of 
completion of canister loading to breakthrough, the fuel tank(s) shall 
be further filled to 95 percent of nominal tank capacity determined to 
the nearest one-tenth of a U.S. gallon (0.38 liter) with the fuel 
specified in Sec.86.113-94. During this fueling operation, the 
refueling emissions canister(s) shall be disconnected, unless the 
manufacturer specifies that the canister(s) should not be disconnected. 
Following completion of refueling, the refueling emissions canister(s) 
shall be reconnected, if the canister was disconnected during refueling. 
Special care shall be taken during this step to avoid damage to the 
components and the integrity of the fuel system. Vehicle driving to 
purge the refueling canister(s) shall be performed using either the 
chassis dynamometer procedure or the test track procedure, as described 
in paragraphs (d)(1) and (d)(2) of this section. The Administrator may 
choose to shorten the vehicle driving for a partial refueling test as 
described in paragraph (d)(3) of this section. For vehicles equipped 
with dual fuel tanks, the required volume of fuel shall be driven out of 
one tank, the second tank shall be selected as the fuel source, and the 
required volume of fuel shall be driven out of the second tank.
    (1) Chassis dynamometer procedure. (i) Vehicle driving on a chassis 
dynamometer shall consist of repeated drives with the UDDS until 85 
percent of fuel tank capacity has been consumed. Driving in testing 
performed by manufacturers may be terminated before 85 percent of the 
fuel tank capacity has been consumed, provided that driving is not 
terminated partway through a UDDS cycle. Driving in testing performed by 
the Administrator may be terminated after the same number of UDDS cycles 
as driven in the manufacturer's certification testing.
    (ii) Except with the advance approval of the Administrator, the 
number of UDDSs required to consume 85 percent of tank fuel capacity 
(total capacity of both tanks when the vehicle is equipped with dual 
fuel tanks) shall be determined from the fuel economy on the UDDS 
applicable to the test vehicle and from the number of gallons to the 
nearest 0.1 gallon (0.38 liter) that constitutes 85 percent of tank 
volume. If this ``fuel consumed point'' occurs partway through a UDDS 
cycle, the cycle shall be completed in its entirety.
    (iii) For vehicles equipped with dual fuel tanks, fuel switching 
from the first tank to the second tank shall occur at the 10 percent 
volume of the first tank regardless of the point in the UDDS cycle at 
which this occurs.
    (iv) If necessary to accommodate work schedules, the engine may be 
turned off and the vehicle parked on the dynamometer. The vehicle may be 
parked off of the dynamometer to facilitate maintenance or repairs if 
required.
    (v) During the driving on the dynamometer, a cooling fan(s) shall be 
positioned as described in Sec.86.135-94(b).

[[Page 730]]

    (2) Test track procedure. (i) Vehicle driving on a test track shall 
consist of repeated drives with the UDDS until 85 percent of fuel tank 
capacity has been consumed. Driving performed by manufacturers may be 
terminated before 85 percent of the fuel tank capacity has been 
consumed, provided that driving is not terminated partway through a UDDS 
cycle. Driving performed by the Administrator may be terminated after 
the same number of UDDS cycles as driven in the manufacturer's 
certification testing.
    (ii) If the distance from the emission laboratory to the test track 
is less than 5 miles (8.05 km) the vehicle may be driven to the test 
track at a speed not to exceed 25 mph. If the distance is greater than 5 
miles (8.05 km) the vehicle shall be moved to the test track with the 
engine off.
    (iii) Except with the advance approval of the Administrator, the 
number of UDDSs required to consume 85 percent of tank fuel capacity 
(total capacity of both tanks when the vehicle is equipped with dual 
fuel tanks) shall be determined from the fuel economy on the UDDS 
applicable to the test vehicle and from the number of gallons to the 
nearest 0.1 gallon (0.38 liter) that constitutes 85 percent of tank 
volume. If this ``fuel consumed point'' occurs partway through a UDDS 
cycle, the cycle shall be completed in its entirety.
    (iv) The vehicle shall be driven at a speed not to exceed 25 mph 
from the test track to the laboratory provided the distance from the 
test track to the laboratory does not exceed 5 miles (8.05 km). If the 
distance from the test track to the emission laboratory is greater than 
5 miles (8.05 km) the vehicle shall be moved from the test track with 
the engine off.
    (v) For vehicles equipped with dual fuel tanks, fuel switching from 
the first tank to the second tank shall occur at the 10 percent volume 
of the first tank regardless of the point in the UDDS cycle at which 
this occurs.
    (vi) If necessary to accommodate work schedules, the engine may be 
turned off and the vehicle parked on the test track. The vehicle may be 
parked off of the test track to facilitate maintenance or repairs if 
required. If the vehicle is moved from the test track, it shall be 
returned to the track with the engine off when mileage accumulation is 
to be resumed.
    (3) Drive schedule for partial refueling test. The Administrator may 
conduct a partial refueling test involving a shortening of the drive 
procedures described in paragraphs (d) (1) and (2) of this section and a 
modified soak and refueling procedure as described in paragraph (e) of 
this section and Sec.86.154-98(e)(7)(i). The drive shall be performed 
as described in paragraph (d) (1) or (2) of this section except that the 
drive shall be terminated when at least 10 percent but no more than 85 
percent of the fuel tank nominal capacity has been consumed and not 
partway through a UDDS cycle. The amount of fuel consumed in the drive 
shall be determined by multiplying the number of UDDSs driven by the 
mileage accumulated per UDDS and dividing by the fuel economy for the 
UDDS applicable to the test vehicle.
    (e) Vehicle cool down--(1) Partial refueling test. If the 
Administrator is conducting the non-integrated system partial refueling 
test, after the driving procedure specified in paragraph (d)(3) of this 
section, the vehicle shall be parked (without starting the engine) and 
soaked at 803 [deg]F (271.7 
[deg]C) for a minimum of 1 hour and a maximum of 6 hours.
    (2) For all other refueling emission tests. Within 10 minutes of 
completion of refueling emissions canister stabilization (see paragraph 
(c) or (d) of this section), the refueling emissions canister(s) shall 
be disconnected, unless the manufacturer specifies that the refueling 
canister(s) should not be disconnected. Within 60 minutes of completion 
of refueling emissions canister stabilization (see paragraph (c) or (d) 
of this section), the vehicle fuel tank(s) shall be drained, the fuel 
tank(s) fueled to 10 percent of nominal tank capacity determined to the 
nearest one-tenth of a U.S. gallon (0.38 liter) with the specified fuel, 
and the vehicle parked (without starting the engine) and soaked at 
803 [deg]F (271.7 [deg]C) 
for a minimum of 6 hours and a maximum of 24 hours.

Sec.86.154-98  Measurement procedure; refueling test.

    (a) The refueling test measurement procedure described in this 
section immediately follows the vehicle and canister preconditioning 
described in Sec.86.153-98.
    (b) The refueling emission enclosure shall be purged for several 
minutes immediately prior to the test. Warning: If at any time the 
concentration of hydrocarbons, of methanol, or of methanol and 
hydrocarbons exceeds 15,000 ppm C, the enclosure should be immediately 
purged. This concentration provides a 4:1 safety factor against the lean 
flammability limit.
    (c)(1) The FID (or HFID) hydrocarbon analyzer, and additional 
analyzer, if needed, shall be zeroed and spanned immediately prior to 
the test.
    (2) For methanol-fueled vehicles only, impingers charged with known 
volumes of pure deionized water shall be placed in the methanol sampling 
system.
    (d) If not already on, the enclosure mixing fan and the spilled fuel 
mixing blower shall be turned on at this time.
    (e) The refueling emission measurement portion of the refueling test 
shall be performed as follows:
    (1) The line from the fuel tank(s) to the refueling emissions 
canister(s) shall be connected.
    (2) The test vehicle, with the engine shut off, shall be moved into 
the enclosure. The test vehicle windows and luggage compartment shall be 
opened if not already open.
    (3) An electrical ground shall be attached to the vehicle. The 
vehicle fuel filler cap shall be removed and the enclosure door shall be 
closed and sealed within two minutes of cap removal. The FID (or HFID) 
trace shall be allowed to stabilize.
    (4) The dispensed fuel temperature recording system shall be 
started.
    (5)(i) Within 10 minutes of closing and sealing the doors, analyze 
enclosure atmosphere for hydrocarbons and record. This is the initial 
(time = 0 minutes) hydrocarbon concentration, CHCi, required 
in Sec.86.143-96.
    (ii) For methanol-fueled vehicles only, measure the initial 
concentration of methanol as described in Sec.86.133-96(i)(6).
    (6) Within one minute of obtaining the initial FID (or HFID) 
reading, and methanol reading if applicable, the fuel nozzle shall be 
inserted into the filler neck of the test vehicle, to its maximum 
penetration, and the refueling operation shall be started. The plane of 
the nozzle's handle shall be approximately perpendicular to the floor of 
the laboratory. The fuel shall be dispensed at a temperature of 671.5 [deg]F (19.40.8 [deg]C) and at 
a dispensing rate of 9.80.3 gal/min (37.11.1 liter/min). In testing conducted by the 
Administrator, a lower dispensing rate (no lower than 4.0 gal/min (15.1 
liter/min)) may be used.
    (7)(i) Partial refueling test. If the Administrator conducts the 
non-integrated system partial refueling test, the fuel flow shall 
continue until the amount of fuel pumped is equal to the fuel consumed 
during the driving, as determined in accordance with Sec.86.153-
98(d)(3). The final volume of fuel dispensed must be within one-tenth of 
a U.S. gallon (0.38 liter) of the targeted amount. If automatic nozzle 
shut-off occurs prior to this point, the nozzle shall be reactivated 
within 15 seconds and fuel dispensing continued as needed. A minimum of 
3 seconds shall elapse between any automatic shutoff and subsequent 
resumption of dispensing.
    (ii) For all other refueling tests. The fuel flow shall continue 
until the refueling nozzle automatic shut-off is activated. The amount 
of fuel dispensed must be at least 85 percent of nominal fuel tank 
volume, determined to the nearest one-tenth of a U.S. gallon (0.38 
liter). If automatic nozzle shut-off occurs prior to this point, the 
nozzle shall be reactivated within 15 seconds and fuel dispensing 
continued as needed. A minimum of 3 seconds shall elapse between any 
automatic shutoff and subsequent resumption of dispensing. Dispensing 
may not be manually terminated, unless the test vehicle has already 
clearly failed the test.
    (8)(i) The final reading of the evaporative enclosure FID analyzer 
shall be taken 605 seconds following the final 
shut-off of fuel flow. This is the final hydrocarbon concentration, 
CHCf, required in Sec.86.143-96. The elapsed time, in 
minutes, between the initial and

[[Page 732]]

final FID (or HFID) readings shall be recorded.
    (ii) For methanol-fueled vehicles only. Measure the final 
concentration of methanol as described in Sec.86.133-96(m)(2).
    (9) For vehicles equipped with more than one fuel tank, the 
procedures described in this section shall be performed for each fuel 
tank.

Sec.86.156-98  Calculations; refueling test.

    (a) The calculation of the net hydrocarbon mass change and methanol 
mass change (if applicable) in the enclosure is used to determine 
refueling mass emissions. The mass is calculated from initial and final 
hydrocarbon and methanol (if applicable) concentrations in ppm carbon, 
initial and final enclosure ambient temperatures, initial and final 
barometric pressures, and net enclosure volume using the equations of 
Sec.86.143-96. For vehicles with multiple tanks, the results for each 
tank shall be calculated and then summed to determine overall refueling 
emissions.
    (b) The final results for comparison with the refueling control 
emission standard shall be computed by dividing the total refueling mass 
emissions by the total gallons of fuel dispensed in the refueling test 
(see Sec.86.154-98(e)(7)(ii)).
    (c) The results of all emission tests shall be rounded, in 
accordance with ASTM E 29-67 (reapproved 1980) (as referenced in Sec.
86.094-28(a)(4)(i)(B)(2)(ii)) to the number of decimal places contained 
in the applicable emission standard expressed to one additional 
significant figure.

specified in paragraph (f) of this section.
    (f) Calculations. (1) The calculation of the net hydrocarbon mass 
change in the enclosure is used to determine refueling mass emissions. 
The mass is calculated from initial and final hydrocarbon concentrations 
in ppm carbon, initial and final enclosure ambient temperatures, initial 
and final barometric pressures and net volume using the equations of 
Sec.86.143. For vehicles with multiple tanks, the results for each 
tank shall be calculated and then

[[Page 734]]

summed to determine overall refueling emissions.
    (2) The final results for comparison with the refueling control 
emission standard shall be computed by dividing the total refueling mass 
emissions by the total gallons of fuel dispensed in the refueling test 
(see paragraph (d)(3) of this section).
    (3) The results of all emission tests shall be rounded, in 
accordance with ASTM E 29-67 to the number of decimal places contained 
in the applicable emission standard expressed to one additional 
significant figure. This procedure has been incorporated by reference 
(see Sec.86.1).

Sec.86.158-00  Supplemental Federal Test Procedures; overview.

    The procedures described in Sec. Sec.86.158-00, 86.159-00, 86.160-
00, and 86.162-00 discuss the aggressive driving (US06) and air 
conditioning (SC03) elements of the Supplemental Federal Test Procedures 
(SFTP). These test procedures consist of two separable test elements: A 
sequence of vehicle operation that tests exhaust emissions with a 
driving schedule (US06) that tests exhaust emissions under high speeds 
and accelerations (aggressive driving); and a sequence of vehicle 
operation that tests exhaust emissions with a driving schedule (SC03) 
which includes the impacts of actual air conditioning operation. These 
test procedures (and the associated standards set forth in subpart S of 
this part) are applicable to light-duty vehicles and light-duty trucks.
    (a) Vehicles are tested for the exhaust emissions of THC, CO, 
NOX. CH4, and CO2. For diesel-cycle 
vehicles, THC is sampled and analyzed continuously according to the 
provisions of Sec.86.110.
    (b) Each test procedure follows the vehicle preconditioning 
specified in Sec.86.132-00.
    (c) US06 Test Cycle. The test procedure for emissions on the US06 
driving schedule (see Sec.86.159-00) is designed to determine gaseous 
exhaust emissions from light-duty vehicles and light-duty trucks while 
simulating high speed and acceleration on a chassis dynamometer 
(aggressive driving). The full test consists of preconditioning the 
engine to a hot stabilized condition, as specified in Sec.86.132-00, 
and an engine idle period of 1 to 2 minutes, after which the vehicle is 
accelerated into the US06 cycle. A proportional part of the diluted 
exhaust is collected continuously for subsequent analysis, using a 
constant volume (variable dilution) sampler or critical flow venturi 
sampler.
    (d) SC03 Test Cycle. The test procedure for determining exhaust 
emissions with the air conditioner operating (see Sec.86.160-00) is 
designed to determine gaseous exhaust emissions from light-duty vehicles 
and light-duty trucks while simulating an urban trip during ambient 
conditions of 95 [deg]F, 100 grains of water/pound of dry air 
(approximately 40 percent relative humidity), and a solar heat load 
intensity of 850 W/m\2\. The full test consists of vehicle 
preconditioning (see Sec.86.132-00 paragraphs (o) (1) and (2)), an 
engine key-off 10 minute soak, an engine start, and operation over the 
SC03 cycle. A proportional part of the diluted exhaust is collected 
continuously during the engine start and the SC03 driving cycle for 
subsequent analysis, using a constant volume (variable dilution) sampler 
or critical flow venturi sampler.
    (e) The emission results from the aggressive driving test (Sec.
86.159-00), air conditioning test (Sec.86.160-00), and a FTP test 
(Sec.86.130-00 (a) through (d) and (f)) (conducted on a large single 
roll or equivalent dynamometer) are analyzed according to the 
calculation methodology in Sec.86.164-00 and compared to the 
applicable SFTP emission standards in subpart A of this part (Sec. Sec.
86.108-00 and 86.109-00).
    (f) These test procedures may be run in any sequence that maintains 
the applicable preconditioning elements specified in Sec.86.132-00.

Sec.86.158-08  Supplemental Federal Test Procedures; overview.

    The procedures described in Sec. Sec.86.158-08, 86.159-08, 86.160-
00, and 86.162-00 discuss the aggressive driving (US06) and air

emissions under high speeds and accelerations (aggressive driving); and 
a sequence of vehicle operation that tests exhaust emissions with a 
driving schedule (SC03) which includes the impacts of actual air 
conditioning operation. These test procedures (and the associated 
standards set forth in subpart S of this part) are applicable to light-
duty vehicles and light-duty trucks.
    (a) Vehicles are tested for the exhaust emissions of THC, CO, 
NOX, CH4, and CO2. For diesel-cycle 
vehicles, THC is sampled and analyzed continuously according to the 
provisions of Sec.86.110.
    (b) Each test procedure follows the vehicle preconditioning 
specified in Sec.86.132-00.
    (c) US06 Test Cycle. The test procedure for emissions on the US06 
driving schedule (see Sec.86.159-08) is designed to determine gaseous 
exhaust emissions from light-duty vehicles and light-duty trucks while 
simulating high speed and acceleration on a chassis dynamometer 
(aggressive driving). The full test consists of preconditioning the 
engine to a hot stabilized condition, as specified in Sec.86.132-00, 
and an engine idle period of 1 to 2 minutes, after which the vehicle is 
accelerated into the US06 cycle. A proportional part of the diluted 
exhaust is collected continuously for subsequent analysis, using a 
constant volume (variable dilution) sampler or critical flow venturi 
sampler. Optionally, as specified in Sec.86.159-08 and in part 600 of 
this chapter, a proportional part of the diluted exhaust may be 
collected continuously in two bag samples, one representing US06 City 
driving and the other representing US06 Highway driving. If two bag 
samples are collected, for petroleum-fueled diesel-cycle vehicles for 
which THC is sampled and analyzed continuously according to the 
provisions of Sec.86.110, the analytical system shall be configured to 
calculate THC for the US06 City phase and the US06 Highway phase as 
described in Sec.86.159-08.
    (d) SC03 Test Cycle. The test procedure for determining exhaust 
emissions with the air conditioner operating (see Sec.86.160-00) is 
designed to determine gaseous exhaust emissions from light-duty vehicles 
and light-duty trucks while simulating an urban trip during ambient 
conditions of 95 [deg]F, 100 grains of water/pound of dry air 
(approximately 40 percent relative humidity), and a solar heat load 
intensity of 850 W/m\2\. The full test consists of vehicle 
preconditioning (see Sec.86.132-00 paragraphs (o)(1) and (2)), an 
engine key-off 10 minute soak, an engine start, and operation over the 
SC03 cycle. A proportional part of the diluted exhaust is collected 
continuously during the engine start and the SC03 driving cycle for 
subsequent analysis, using a constant volume (variable dilution) sampler 
or critical flow venturi sampler.
    (e) The emission results from the aggressive driving test (Sec.
86.159-08), air conditioning test (Sec.86.160-00), and FTP test (Sec.
86.130-00 (a) through (d) and (f)) (conducted on a large single roll or 
equivalent dynamometer) are analyzed according to the calculation 
methodology in Sec.86.164-08 and compared to the applicable SFTP 
emission standards in subpart S of this part.
    (f) These test procedures may be run in any sequence that maintains 
the applicable preconditioning elements specified in Sec.86.132-00.

[71 FR 77920, Dec. 27, 2006]



Sec.86.159-00  Exhaust emission test procedures for US06 emissions.

    (a) Overview. The dynamometer operation consists of a single, 600 
second test on the US06 driving schedule, as described in appendix I, 
paragraph (g), of this part. The vehicle is preconditioned in accordance 
with Sec.86.132-00, to bring it to a warmed-up stabilized condition. 
This preconditioning is followed by a 1 to 2 minute idle period that 
proceeds directly into the US06 driving schedule during which continuous 
proportional samples of gaseous emissions are collected for analysis. If 
engine stalling should occur during cycle operation, follow the 
provisions of Sec.86.136-90 (engine starting and restarting). For 
gasoline-fueled Otto-cycle vehicles, the composite samples collected in 
bags are analyzed for THC, CO, CO2, CH4, and 
NOX. For petroleum-fueled diesel-cycle vehicles, THC is 
sampled and analyzed continuously according to the provisions of Sec.
86.110. Parallel bag samples of

[[Page 736]]

dilution air are analyzed for THC, CO, CO2, CH4, 
and NOX.
    (b) Dynamometer activities. (1) All official US06 tests shall be run 
on a large single roll electric dynamometer, or an approved equivalent 
dynamometer configuration, that satisfies the requirements of Sec.
86.108-00.
    (2) Position (vehicle can be driven) the test vehicle on the 
dynamometer and restrain.
    (3) Required US06 schedule test dynamometer inertia weight class 
selections are determined by the test vehicles test weight basis and 
corresponding equivalent weight as listed in the tabular information of 
Sec.86.129-94(a) and discussed in Sec.86.129-00 (e) and (f).
    (4) Set the dynamometer test inertia weight and roadload horsepower 
requirements for the test vehicle (see Sec.86.129-00 (e) and (f). The 
dynamometer's horsepower adjustment settings shall be set to match the 
force imposed during dynamometer operation with actual road load force 
at all speeds.
    (5) The vehicle speed as measured from the dynamometer rolls shall 
be used. A speed vs. time recording, as evidence of dynamometer test 
validity, shall be supplied on request of the Administrator.
    (6) The drive wheel tires may be inflated up to a gauge pressure of 
45 psi (310 kPa), or the manufacturer's recommended pressure if higher 
than 45 psi, in order to prevent tire damage. The drive wheel tire 
pressure shall be reported with the test results.
    (7) The driving distance, as measured by counting the number of 
dynamometer roll or shaft revolutions, shall be determined for the test.
    (8) Four-wheel drive and all-wheel drive vehicles may be tested 
either in a four-wheel drive or a two-wheel drive mode of operation. In 
order to test in the two-wheel drive mode, four-wheel drive and all-
wheel drive vehicles may have one set of drive wheels disengaged; four-
wheel and all-wheel drive vehicles which can be shifted to a two-wheel 
mode by the driver may be tested in a two-wheel drive mode of operation.
    (9) During dynamometer operation, a fixed speed cooling fan with a 
maximum discharge velocity of 15,000 cfm will be positioned so as to 
direct cooling air to the vehicle in an appropriate manner with the 
engine compartment cover open. In the case of vehicles with front engine 
compartments, the fan shall be positioned within 24 inches (61 
centimeters) of the vehicle. In the case of vehicles with rear engine 
compartments (or if special designs make the above impractical), the 
cooling fan(s) shall be placed in a position to provide sufficient air 
to maintain vehicle cooling. The Administrator may approve modified 
cooling configurations or additional cooling if necessary to 
satisfactorily perform the test. In approving requests for additional or 
modified cooling, the Administrator will consider such items as actual 
road cooling data and whether such additional cooling is needed to 
provide a representative test.
    (c) The flow capacity of the CVS shall be large enough to virtually 
eliminate water condensation in the system.
    (d) Practice runs over the prescribed driving schedule may be 
performed at test point, provided an emission sample is not taken, for 
the purpose of finding the appropriate throttle action to maintain the 
proper speed-time relationship, or to permit sampling system adjustment.
    (e) Perform the test bench sampling sequence outlined in Sec.
86.140-94 prior to or in conjunction with each series of exhaust 
emission measurements.
    (f) Test activities. (1) The US06 consists of a single test which is 
directly preceded by a vehicle preconditioning in accordance with Sec.
86.132-00. Following the vehicle preconditioning, the vehicle is idled 
for not less than one minute and not more than two minutes. The 
equivalent dynamometer mileage of the test is 8.0 miles (1.29 km).
    (2) The following steps shall be taken for each test:
    (i) Immediately after completion of the preconditioning, idle the 
vehicle. The idle period is not to be less than one minute or not 
greater than two minutes.
    (ii) With the sample selector valves in the ``standby'' position, 
connect evacuated sample collection bags to

[[Page 737]]

the dilute exhaust and dilution air sample collection systems.
    (iii) Start the CVS (if not already on), the sample pumps, the 
temperature recorder, the vehicle cooling fan, and the heated THC 
analysis recorder (diesel-cycle only). The heat exchanger of the 
constant volume sampler, if used, petroleum-fueled diesel-cycle THC 
analyzer continuous sample line should be preheated to their respective 
operating temperatures before the test begins.
    (iv) Adjust the sample flow rates to the desired flow rate and set 
the gas flow measuring devices to zero.
    (A) For gaseous bag samples (except THC samples), the minimum flow 
rate is 0.17 cfm (0.08 liters/sec).
    (B) For THC samples, the minimum FID (or HFID in the case of diesel-
cycle vehicles) flow rate is 0.066 cfm (0.031 liters/sec).
    (C) CFV sample flow rate is fixed by the venturi design.
    (v) Attach the exhaust tube to the vehicle tailpipe(s).
    (vi) Start the gas flow measuring device, position the sample 
selector valves to direct the sample flow into the exhaust sample bag, 
the dilution air sample bag, turn on the petroleum-fueled diesel-cycle 
THC analyzer system integrator, mark the recorder chart, and record both 
gas meter or flow measurement instrument readings, (if applicable).
    (vii) Place vehicle in gear after starting the gas flow measuring 
device, but prior to the first acceleration. Begin the first 
acceleration 5 seconds after starting the measuring device.
    (viii) Operate the vehicle according to the US06 driving schedule, 
as described in appendix I, paragraph (g), of this part. Manual 
transmission vehicles shall be shifted according to the manufacturer 
recommended shift schedule, subject to review and approval by the 
Administrator. For further guidance on transmissions see Sec.86.128-
00.
    (ix) Turn the engine off 2 seconds after the end of the last 
deceleration (i.e., engine off at 596 seconds).
    (x) Five seconds after the engine stops running, simultaneously turn 
off gas flow measuring device No. 1 (and the petroleum-fueled diesel 
hydrocarbon integrator No. 1 and mark the petroleum-fueled diesel 
hydrocarbon recorder chart if applicable) and position the sample 
selector valves to the ``standby'' position. Record the measured roll or 
shaft revolutions and the No. 1 gas meter reading or flow measurement 
instrument.
    (xi) As soon as possible, transfer the exhaust and dilution air bag 
samples to the analytical system and process the samples according to 
Sec.86.140-94 obtaining a stabilized reading of the bag exhaust sample 
on all analyzers within 20 minutes of the end of the sample collection 
phase of the test.
    (xii) Immediately after the end of the sample period, turn off the 
cooling fan, close the engine compartment cover, disconnect the exhaust 
tube from the vehicle tailpipe(s), and drive the vehicle from 
dynamometer.
    (xiii) The CVS or CFV may be turned off, if desired.

Sec.86.159-08  Exhaust emission test procedures for US06 emissions.

    (a) Overview. The dynamometer operation consists of a single, 600 
second test on the US06 driving schedule, as described in appendix I, 
paragraph (g), of this part. The vehicle is preconditioned in accordance 
with Sec.86.132-00, to bring it to a warmed-up stabilized condition. 
This preconditioning is followed by a 1 to 2 minute idle period that 
proceeds directly into the US06 driving schedule during which continuous 
proportional samples of gaseous emissions are collected for analysis. 
US06 emissions may optionally be collected in two bag samples 
representing US06 City and US06 Highway emissions, as provided for in 
this section and in part 600 of this chapter. Emissions from seconds 0-
130 and seconds 495-596 are collected in one bag to represent US06 City 
emissions, and emissions from seconds 130-495 are collected in a second 
bag to represent US06 Highway emissions. If engine stalling should occur 
during cycle operation, follow the provisions of Sec.86.136-90 (engine 
starting and restarting). For gasoline-fueled Otto-cycle vehicles, the 
composite samples collected in bags

[[Page 738]]

are analyzed for THC, CO, CO2, CH4, and 
NOX. For petroleum-fueled diesel-cycle vehicles, THC is 
sampled and analyzed continuously according to the provisions of Sec.
86.110. Parallel bag samples of dilution air are analyzed for THC, CO, 
CO2, CH4, and NOX.
    (b) Dynamometer activities. (1) All official US06 tests shall be run 
on a large single roll electric dynamometer, or an approved equivalent 
dynamometer configuration, that satisfies the requirements of Sec.
86.108-00.
    (2) Position (vehicle can be driven) the test vehicle on the 
dynamometer and restrain.
    (3) Required US06 schedule test dynamometer inertia weight class 
selections are determined by the test vehicles test weight basis and 
corresponding equivalent weight as listed in the tabular information of 
Sec.86.129-94(a) and discussed in Sec.86.129-00 (e) and (f).
    (4) Set the dynamometer test inertia weight and roadload horsepower 
requirements for the test vehicle according to Sec.86.129-00 (e) and 
(f). The dynamometer's horsepower adjustment settings shall be set to 
match the force imposed during dynamometer operation with actual road 
load force at all speeds.
    (5) The vehicle speed as measured from the dynamometer rolls shall 
be used. A speed vs. time recording, as evidence of dynamometer test 
validity, shall be supplied on request of the Administrator.
    (6) The drive wheel tires may be inflated up to a gauge pressure of 
45 psi (310 kPa), or the manufacturer's recommended pressure if higher 
than 45 psi, in order to prevent tire damage. The drive wheel tire 
pressure shall be reported with the test results.
    (7) The driving distance, as measured by counting the number of 
dynamometer roll or shaft revolutions, shall be determined for the test.
    (8) Four-wheel drive and all-wheel drive vehicles may be tested 
either in a four-wheel drive or a two-wheel drive mode of operation. In 
order to test in the two-wheel drive mode, four-wheel drive and all-
wheel drive vehicles may have one set of drive wheels disengaged; four-
wheel and all-wheel drive vehicles which can be shifted to a two-wheel 
mode by the driver may be tested in a two-wheel drive mode of operation.
    (9) During dynamometer operation, a fixed speed cooling fan with a 
maximum discharge velocity of 15,000 cfm will be positioned so as to 
direct cooling air to the vehicle in an appropriate manner with the 
engine compartment cover open. In the case of vehicles with front engine 
compartments, the fan shall be positioned within 24 inches (61 
centimeters) of the vehicle. In the case of vehicles with rear engine 
compartments (or if special designs make the above impractical), the 
cooling fan(s) shall be placed in a position to provide sufficient air 
to maintain vehicle cooling. The Administrator may approve modified 
cooling configurations, additional cooling, variable speed fan(s), and/
or a closed engine compartment cover if necessary to satisfactorily 
perform the test. In approving requests for additional or modified 
cooling, the Administrator will consider such items as actual road 
cooling data and whether such additional cooling is needed to provide a 
representative test. For example, the hood may be closed to provide 
adequate air flow to an intercooler through a factory installed hood 
scoop. Additionally, the Administrator may conduct certification, fuel 
economy and in-use testing using the additional cooling set-up approved 
for a specific vehicle.
    (c) The flow capacity of the CVS shall be large enough to virtually 
eliminate water condensation in the system.
    (d) Practice runs over the prescribed driving schedule may be 
performed at test point, provided an emission sample is not taken, for 
the purpose of finding the appropriate throttle action to maintain the 
proper speed-time relationship, or to permit sampling system adjustment.
    (e) Perform the test bench sampling sequence outlined in Sec.
86.140-94 prior to or in conjunction with each series of exhaust 
emission measurements.
    (f) Test activities. (1) The US06 consists of a single test which is 
directly preceded by a vehicle preconditioning in accordance with Sec.
86.132-00. Following the vehicle preconditioning, the vehicle is idled 
for not less than one

[[Page 739]]

minute and not more than two minutes. The equivalent dynamometer mileage 
of the test is 8.0 miles (1.29 km).
    (2) The following steps shall be taken for each test:
    (i) Immediately after completion of the preconditioning, idle the 
vehicle. The idle period is not to be less than one minute or greater 
than two minutes.
    (ii) With the sample selector valves in the ``standby'' position, 
connect evacuated sample collection bags to the dilute exhaust and 
dilution air sample collection systems.
    (iii) Start the CVS (if not already on), the sample pumps, the 
temperature recorder, the vehicle cooling fan, and the heated THC 
analysis recorder (diesel-cycle only). The heat exchanger of the 
constant volume sampler, if used, petroleum-fueled diesel-cycle THC 
analyzer continuous sample line should be preheated to their respective 
operating temperatures before the test begins.
    (iv) Adjust the sample flow rates to the desired flow rate and set 
the gas flow measuring devices to zero.
    (A) For gaseous bag samples (except THC samples), the minimum flow 
rate is 0.17 cfm (0.08 liters/sec).
    (B) For THC samples, the minimum FID (or HFID in the case of diesel-
cycle vehicles) flow rate is 0.066 cfm (0.031 liters/sec).
    (C) CFV sample flow rate is fixed by the venturi design.
    (v) Attach the exhaust tube to the vehicle tailpipe(s).
    (vi) Start the gas flow measuring device, position the sample 
selector valves to direct the sample flow into the exhaust sample bag,

transmission vehicles shall be shifted according to the manufacturer 
recommended shift schedule, subject to review and approval by the 
Administrator. For further guidance on transmissions see Sec.86.128-
00.
    (ix) Paragraphs (f)(2)(ix)(A) and (B) of this section apply to 
vehicles for which the manufacturer is collecting US06 City and US06 
Highway emissions for subsequent analysis according to the provisions of 
part 600 of this chapter. Vehicles for which emissions are being 
collected in a single continuous sample for subsequent analysis must be 
tested according to paragraph (x) of this section, and this paragraph 
(f)(2)(ix) will not apply.
    (A) At two seconds after the end of the deceleration which is 
scheduled to occur at 128 seconds (i.e., at 130 seconds), simultaneously 
switch the sample flows from the ``US06 City'' bags and samples to the 
``US06 Highway'' bags and samples, switch gas flow measuring device No. 
1 (and the petroleum-fueled diesel hydrocarbon integrator No. 1 and mark 
the petroleum-fueled diesel hydrocarbon recorder chart if applicable) to 
``standby'' mode, and start gas flow measuring device No. 2 (and the 
petroleum-fueled diesel hydrocarbon integrator No. 2 if applicable). 
Before the acceleration which is scheduled to occur at 136 seconds,

Sec.86.160-00  Exhaust emission test procedure for SC03 emissions.

    (a) Overview. The dynamometer operation consists of a single, 600 
second test on the SC03 driving schedule, as described in appendix I, 
paragraph (h), of this part. The vehicle is preconditioned, in 
accordance with Sec.86.132-00 of this subpart, to bring the vehicle to 
a warmed-up stabilized condition. This preconditioning is followed by a 
10 minute vehicle soak (engine off) that proceeds directly into the SC03 
driving schedule, during which continuous proportional samples of 
gaseous emissions are collected for analysis. The entire test, including 
the preconditioning driving, vehicle soak, and SC03 official test cycle, 
is either conducted in an environmental test facility or under test 
conditions that simulates testing in an environmental test cell (see 
Sec.86.162-00 (a) for a discussion of simulation procedure approvals). 
The environmental test facility must be capable of providing the 
following nominal ambient test conditions of: 95 [deg]F air temperature, 
100 grains of water/pound of dry air (approximately 40 percent relative 
humidity), a solar heat load intensity of 850 W/m\2\, and vehicle 
cooling air flow proportional to vehicle speed. Section 86.161-00 
discusses the minimum facility requirements and corresponding control 
tolerances for air conditioning ambient test conditions. The vehicle's 
air conditioner is operated or appropriately simulated for the duration 
of the test procedure (except for the vehicle 10 minute soak), including 
the preconditioning. For gasoline-fueled Otto-cycle vehicles, the 
composite samples collected in bags are analyzed for THC, CO, 
CO2, CH4, and NOX. For petroleum-fueled 
diesel-cycle vehicles, THC is sampled and analyzed continuously 
according to the provisions of Sec.86.110. Parallel bag samples of 
dilution air are analyzed for THC, CO, CO2, CH4, 
and NOX.
    (b) Dynamometer activities. (1) All official air conditioning tests 
shall be run on a large single roll electric dynamometer or an 
equivalent dynamometer configuration that satisfies the requirements of 
Sec.86.108-00.
    (2) Position (vehicle can be driven) the test vehicle on the 
dynamometer and restrain.
    (3) Required SC03 schedule test dynamometer inertia weight class 
selections are determined by the test vehicles test weight basis and 
corresponding equivalent weight as listed in the tabular information of 
Sec.86.129-00(a) and discussed in Sec.86.129-00 (e) and (f).
    (4) Set the dynamometer test inertia weight and roadload horsepower 
requirements for the test vehicle (see Sec.86.129-00 (e) and (f)). The 
dynamometer's horsepower adjustment

[[Page 741]]

settings shall be set such that the force imposed during dynamometer 
operation matches actual road load force at all speeds.
    (5) The vehicle speed as measured from the dynamometer rolls shall 
be used. A speed vs. time recording, as evidence of dynamometer test 
validity, shall be supplied at request of the Administrator.
    (6) The drive wheel tires may be inflated up to a gauge pressure of 
45 psi (310 kPa), or the manufacturer's recommended pressure if higher 
than 45 psi, in order to prevent tire damage. The drive wheel tire 
pressure shall be reported with the test results.
    (7) The driving distance, as measured by counting the number of 
dynamometer roll or shaft revolutions, shall be determined for the test.
    (8) Four-wheel drive and all-wheel drive vehicles may be tested 
either in a four-wheel drive or a two-wheel drive mode of operation. In 
order to test in the two-wheel drive mode, four-wheel drive and all-
wheel drive vehicles may have one set of drive wheels disengaged; four-
wheel and all-wheel drive vehicles which can be shifted to a two-wheel 
mode by the driver may be tested in a two-wheel drive mode of operation.
    (c) Vehicle and test activities for testing in a full environmental 
cell. The SFTP air conditioning test in an environmental test cell is 
composed of the following sequence of activities. Alternative procedures 
which appropriately simulate full environmental cell testing may be 
approved under the provisions of Sec. Sec.86.162-00(a) and 86.163-00.
    (1) Drain and fill the vehicle's fuel tank to 40 percent capacity 
with test fuel. If a vehicle has gone through the drain and fuel 
sequence less than 72 hours previously and has remained under laboratory 
ambient temperature conditions, this drain and fill operation can be 
omitted (see Sec.86.132-00(c)(2)(ii)).
    (2)(i) Position the variable speed cooling fan in front of the test 
vehicle with the vehicle's hood down. This air flow should provide 
representative cooling at the front of the test vehicle (air 
conditioning condenser and engine) during the SC03 driving schedule. See 
Sec.86.161-00(e) for a discussion of cooling fan specifications.
    (ii) In the case of vehicles with rear engine compartments (or if 
this front location provides inadequate engine cooling), an additional 
cooling fan shall be placed in a position to provide sufficient air to 
maintain vehicle cooling. The fan capacity shall normally not exceed 
5300 cfm (2.50 m\3\/s). If, however, it can be demonstrated that during 
road operation the vehicle receives additional cooling, and that such 
additional cooling is needed to provide a representative test, the fan 
capacity may be increased or additional fans used if approved in advance 
by the Administrator.
    (3) Close all vehicle windows.
    (4) Connect the emission test sampling system to the vehicle's 
exhaust tail pipe(s).
    (5)(i) Set the environmental test cell ambient test conditions to 
the conditions defined in Sec.86.161-00.
    (ii) Turn on the solar heating system.
    (iii) All vehicle test phases of preconditioning, soak, and the 
official SC03 test cycle are to be performed in this set of ambient test 
conditions.
    (6) Set the air conditioning system controls as follows:
    (i) A/C mode setting at Maximum.
    (ii) Airflow setting at Recirculate, if so equipped.
    (iii) Fan setting at Highest setting.
    (iv) A/C Temperature setting at full cool (for automatic systems set 
at 72 [deg]F).
    (v) Air conditioning controls should be placed in the ``on'' 
position prior to vehicle starting so that the air conditioning system 
is active whenever the engine is running.
    (7) Start the vehicle (with air conditioning system on) and conduct 
a preconditioning cycle as discussed in Sec.86.132-00(o)(1).
    (i) If engine stalling should occur during any air conditioning test 
cycle operation, follow the provisions of Sec.86.136-90 (Engine 
starting and restarting).
    (ii) For manual transmission vehicles, the vehicle shall be shifted 
according the provisions of Sec.86.128-00.
    (8) Following the preconditioning cycle, the test vehicle (and 
consequently the air conditioning system) and cooling fan(s) are turned 
off and the vehicle is allowed to soak in the

[[Page 742]]

ambient conditions of paragraph (c)(5) of this section for 10 1 minutes.
    (9) Start engine (with air conditioning system also running). 
Fifteen seconds after the engine starts, place vehicle in gear.
    (10) Eighteen seconds after the engine starts, begin the initial 
vehicle acceleration of the driving schedule.
    (11) Operate the vehicle according to the SC03 driving schedule, as 
described in appendix I, paragraph (h), of this part.
    (12) Turn the engine off 2 seconds after the end of the last 
deceleration (i.e., engine off at 596 seconds).
    (d) Exhaust Emission Measurement Activities. The following 
activities are performed, when applicable, in order to meet the timing 
of the vehicle test and environmental facility activities.
    (1) Perform the test bench sampling calibration sequence outlined in 
Sec.86.140-94 prior to or in conjunction with each series of exhaust 
emission measurements.
    (2) With the sample selector valves in the ``standby'' position, 
connect evacuated sample collection bags to the dilute exhaust and 
dilution air sample collection systems.
    (3) Start the CVS (if not already on), the sample pumps, the 
temperature recorder, the vehicle cooling fan, and the heated THC 
analysis recorder (diesel-cycle only). The heat exchanger of the 
constant volume sampler, if used, petroleum-fueled diesel-cycle THC 
analyzer continuous sample line should be preheated to their respective 
operating temperatures before the test begins.
    (4) Adjust the sample flow rates to the desired flow rate and set 
the gas flow measuring devices to zero.
    (i) For gaseous bag samples (except THC samples), the minimum flow 
rate is 0.17 cfm (0.08 liters/sec).
    (ii) For THC samples, the minimum FID (or HFID in the case of 
diesel-cycle vehicles) flow rate is 0.066 cfm (0.031 1/sec).
    (iii) CFV sample flow rate is fixed by the venturi design.
    (5) Attach the exhaust tube to the vehicle tailpipe(s).
    (6) Start the gas flow measuring device, position the sample 
selector valves to direct the sample flow into the exhaust sample bag, 
the dilution air sample bag, turn on the petroleum-fueled diesel-cycle 
THC analyzer system integrator, mark the recorder chart, and record both 
gas meter or flow measurement instrument readings, if applicable.
    (7) Start the engine (with air conditioning system also running). 
Fifteen seconds after the engine starts, place vehicle in gear.
    (8) Twenty seconds after the engine starts, begin the initial 
vehicle acceleration of the driving schedule.
    (9) Operate the vehicle according to the SC03 driving schedule.
    (10) Turn the engine off 2 seconds after the end of the last 
deceleration (i.e., engine off at 596 seconds).
    (11) Five seconds after the engine stops running, simultaneously 
turn off gas flow measuring device No. 1 (and the petroleum-fueled 
diesel hydrocarbon integrator No. 1 and mark the petroleum-fueled diesel 
hydrocarbon recorder chart if applicable) and position the sample 
selector valves to the ``standby'' position. Record the measured roll or 
shaft revolutions and the No. 1 gas meter reading or flow measurement 
instrument).
    (12) As soon as possible, transfer the exhaust and dilution air bag 
samples to the analytical system and process the samples according to 
Sec.86.140 obtaining a stabilized reading of the bag exhaust sample on 
all analyzers within 20 minutes of the end of the sample collection 
phase of the test.
    (13) Immediately after the end of the sample period, turn off the 
cooling fan, disconnect the exhaust tube from the vehicle tailpipe(s), 
and drive the vehicle from dynamometer.
    (14) The CVS or CFV may be turned off, if desired.
    (e) NOX humidity correction. Calculated NOX 
exhaust emissions from air conditioning tests conducted in an 
environmental test cell at a nominal 100 grains of water/pound of dry 
air are to be corrected for humidity to 100 grains of water/pound of dry 
air (see the relationship of Sec.86.164-00(d)).

Sec.86.161-00  Air conditioning environmental test facility ambient
requirements.

    The goal of an air conditioning test facility is to simulate the 
impact of an ambient heat load on the power requirements of the 
vehicle's air conditioning compressor while operating on a specific 
driving cycle. The environmental facility control elements that are 
discussed are ambient air temperature and humidity, minimum test cell 
size, solar heating, and vehicle frontal air flow.
    (a) Ambient air temperature. (1) Ambient air temperature is 
controlled, within the test cell, during all phases of the air 
conditioning test sequence to 95 2 [deg]F on 
average and 95 5 [deg]F as an instantaneous 
measurement.
    (2) Air temperature is recorded continuously at a minimum of 30 
second intervals. Records of cell air temperatures and values of average 
test temperatures are maintained by the manufacturer for all 
certification related programs.
    (b) Ambient humidity. (1) Ambient humidity is controlled, within the 
test cell, during all phases of the air conditioning test sequence to an 
average of 100 5 grains of water/pound of dry air.
    (2) Humidity is recorded continuously at a minimum of 30 second 
intervals. Records of cell humidity and values of average test humidity 
are maintained by the manufacturer for all certification related 
programs.
    (c) Minimum test cell size. (1) The recommended minimum 
environmental exhaust emission test cell size is width 20 feet, length 
40 feet, and height 10 feet.
    (2) Test cells with smaller size dimensions may be approved by the 
Administrator if it can be shown that all of the ambient test condition 
performance requirements are satisfied.
    (d) Solar heat loading. (1)(i) Acceptable types of radiant energy 
emitters that may be used for simulating solar heat load are:
    (A) Metal halide;
    (B) Quartz halogen with dichroic mirrors; and
    (C) Sodium iodide.
    (ii) The Administrator will approve other types of radiant energy 
emitters if the manufacturer can show they satisfy the requirements of 
this section.
    (2) The height of the minimal cell size will dictate the type of 
radiant energy source that will satisfy the spectral distribution and 
uniformity definitions of this section.
    (3) Radiant energy specifications. (i) Simulated solar radiant 
energy intensity is determined as an average of the two points measured 
at:
    (A) Centerline of the test vehicle at the base of the windshield.
    (B) Centerline of the vehicle at the base of the rear window (truck 
and van location defined as bottom of vertical window or where an 
optional window would be located).
    (ii) The radiant energy intensity set point is 850 45 watts/square meter.
    (iii) The definition of an acceptable spectral distribution is 
contained in the following table:

                 Definition of the Spectral Distribution
------------------------------------------------------------------------
                                                    Percent of total
                                                        spectrum
            Band width (nanometers)            -------------------------
                                                Lower limit  Upper limit
                                                 (percent)    (percent)

780................................       35           53
------------------------------------------------------------------------
Note: Filter the UV region between 280 and 320 wave lengths.

    (iv) The angle of incidence of radiant energy is defined as 90 
degrees from the test cell floor.
    (v) The requirements for measuring the uniformity of radiant energy 
are:
    (A) The radiant energy uniformity tolerance is 15 percent of the radiant energy intensity set point of 
850 watts/square meter.
    (B) The uniformity of radiant energy intensity is measured at each 
point of a 0.5 meter grid over the entire footprint of the test vehicle 
at the elevation of one meter including the footprint edges.
    (C) Radiant energy uniformity must be checked at least every 500 
hours of emitter usage or every six months depending on which covers the 
shorter time period; and every time major changes in the solar 
simulation hardware occur.

[[Page 744]]

    (vi) The radiant energy intensity measurement instrument 
specifications (minimum) are:
    (A) Sensitivity of 9 microvolts per watt/square meter;
    (B) Response time of 1 second;
    (C) Linearity of 0.5 percent; and
    (D) Cosine of 1 percent from normalization 0-
70 degree zenith angle.
    (e) Vehicle frontal air flow. The Administrator will approve frontal 
air flow based on ``blower in box'' technology as an acceptable 
simulation of environmental air flow cooling for the air conditioning 
compressor and engine, provided the following requirements are 
satisfied.
    (1) The minimum air flow nozzle discharge area must be equal or 
exceed the vehicle frontal inlet area. Optimum discharge area is 18 
square feet (4.25 x 4.25), however, other sizes can be used.
    (2) Air flow volumes must be proportional to vehicle speed. With the 
above optimum discharge size, the fan volume would vary from 0 cubic 
feet/minute (cfm) at 0 mph to approximately 95,000 cfm at 60 mph. If 
this fan is also the only source of cell air circulation or if fan 
operational mechanics make the 0 mph air flow requirement impractical, 
air flow of 2 mph or less will be allowed at 0 mph vehicle speed.
    (3) The fan air flow velocity vector perpendicular to the axial flow 
velocity vector shall be less than 10 percent of the mean velocity 
measured at fan speeds corresponding to vehicle speeds of 20 and 40 mph.
    (4)(i) Fan axial air flow velocity is measured two feet from nozzle 
outlet at each point of a one foot grid over the entire discharge area.
    (ii) The uniformity of axial flow tolerance is 20 percent of the fan 
speeds corresponding to vehicle speeds of 20 and 40 mph.
    (5) The instrument used to verify the air velocity must have an 
accuracy of 2 percent of the measured air flow speed.
    (6) The fan discharge nozzle must be located 2 to 3 feet from the 
vehicle and 0 to 6 inches above the test cell floor during air 
conditioning testing. This applies to non-wind tunnel environmental test 
cells only.
    (7) The design specifications discussed in paragraphs (e)(1) through 
(e)(5) of this section must be verified by the manufacturer prior to 
conducting certification air conditioning tests.

Sec.86.162-03  Approval of alternative air conditioning test
simulations.

    (a) Upon petition from a manufacturer or upon the Agency's own 
initiative, the Administrator will approve a simulation of the 
environmental cell for air conditioning test (SC03) described in Sec.
86.160-00 providing that the procedure can be run by the Administrator 
for SEA and in-use enforcement testing and providing that the following 
criteria are met:
    (1) In deciding whether approvals will be granted, the Administrator 
will consider data showing how well the simulation matches environmental 
cell test data for the range of vehicles to be covered by the simulation 
including items such as the tailpipe emissions, air conditioning 
compressor load, and fuel economy.
    (2) For any simulation approved under paragraph (a) of this section, 
the manufacturer must agree to be subject to an ongoing yearly 
correlation spot check as described in Sec.86.163-00.
    (3) Once a simulation is approved and used by a manufacturer for 
testing for a given vehicle, EPA agrees to use the simulation test 
procedure for all official testing conducted on that vehicle by the 
Agency for certification, SEA, and recall purposes, excluding spot check 
testing and vehicles which fail the spot check criteria as described in 
Sec.86.163-00.
    (4) EPA will moniter the aggregate results of spot check testing and 
full environmental test cells. If EPA determines, based on such 
aggregate results, that any simulation is producing test results 
consistantly below those from a full environmental test cell, EPA may 
review its approval of the simulation.
    (b) [Reserved]

Sec.86.163-00  Spot check correlation procedures for vehicles tested
using a simulation of the environmental test cell for air conditioning
emission testing.

    This section is applicable for vehicles which are tested using a 
simulation of the environmental test cell approved under the provisions 
of Sec.86.162-00(a).
    (a) The Administrator may select up to five emission data vehicles 
(one emission data vehicle for small volume manufacturers), including 
vehicles submitted for running change approval, each model year for any 
manufacturer undergoing the spot checking procedures of this section.
    (b) Testing conducted under this section (including testing 
performed in an environmental test cell) will be considered as official 
data as described in Sec.86.091-29 and used in determining compliance 
with the standards. Such testing must comply with all applicable 
emission standards of subpart A of this part. Retests for the purpose of 
emission compliance will be allowed using the procedures described in 
Sec.86.091-29.
    (c) Spot check procedures. (1) Subject to the limitations of 
paragraphs (a) and (d)(2)(iii) of this section, the Administrator may 
require that one or more of the test vehicles which use a simulation 
rather than actual testing in an environmental test cell for air 
conditioning emission testing be submitted at a place the Administrator 
will designate for air conditioning emission testing in an environmental 
test cell as described in Sec.86.160-00. The Administrator may order 
this testing to be conducted at a manufacturer facility. All 
manufacturers which use a simulation instead of environmental cell 
testing must have access to an environment test cell meeting the 
requirements of Sec.86.161-00 to perform this testing.
    (2) An air conditioning emission test will be performed as described 
in Sec.86.162-00 in a full environmental test cell.
    (i) The results of the original simulation test and the full 
environmental test cell required in paragraph (c)(1) of this section are 
compared. In order to pass the spot check, the test results must pass 
both the following two criteria:
    (A) The NOX emission results of the simulation test must 
be at least 85% of the NOX emission results of the 
environmental chamber test.
    (B) The fuel consumption of the simulation test must be at least 95% 
of the fuel consumption of the environmental chamber test.
    (ii) If either of two criteria of paragraph (c)(2)(i) of this 
section were not met, a retest is allowed. The manufacturer may elect to 
conduct either a retest of the simulation procedure or the environmental 
chamber testing. In order to pass the spot check, the test results must 
pass both the following two criteria using the retest test result.
    (A) The NOX emission results of the simulation test must 
be at least 85% of the NOX emission results of the 
environmental chamber test.
    (B) The fuel consumption of the simulation test must be at least 95% 
of the fuel consumption of the environmental chamber test.
    (iii) If either of the two criteria of paragraph (c)(2)(ii) of this 
section were not met, a second retest is allowed. The procedure not 
selected for the first retest must be used for the second retest, 
yielding two test results for each procedure. In order to pass the spot 
check, the test results must pass both the following two criteria using 
the average test result for each procedure:
    (A) The NOX emission results of the simulation test must 
be at least 85% of the NOX emission results of the 
environmental chamber test.
    (B) The fuel consumption of the simulation test must be at least 95% 
of the fuel consumption of the environmental chamber test.
    (iv) If the spot check criteria have not passed after any of the 
initial test, the first retest, or the second retest the spot check is 
considered failed.
    (d) Consequences of failing a spot check. (1) If the emission 
results of the testing using the environmental test chamber passes all 
the applicable standards, those test results may be used to obtain a 
certificate of conformity.

[[Page 746]]

    (2) The Administrator will allow up to 60 days for the manufacturer 
to supply additional data addressing the correlation of the simulation 
with a full environmental test cell.
    (i) If that data prove to the satisfaction of the Administrator that 
the simulation produces results that correlate sufficiently with the 
environmental test chamber, the Administrator may allow the continued 
use of the simulation.
    (ii) Otherwise, the Administrator will determine that the simulation 
fails to meet adequate correlation levels with full environmental 
testing. As a consequence of this finding, all future air conditioning 
emission testing on the population of vehicles represented by the 
failing-spot-check test vehicle (which may include past model year 
configurations) will be conducted using an environment chamber or a 
different (or corrected) approved simulation procedure.
    (iii) For each vehicle that fails a spot check, the Administrator 
may select up to two additional vehicles to test for the spot check that 
do not count against the five vehicle limit of paragraph (a) of this 
section.
    (e) EPA will monitor the aggregate results of spot check testing and 
full environmental test cells. If EPA determines, based on such 
aggregate results, that any simulation (other than the AC1 and AC2 
procedures described in paragraphs (b) and (c) of this section for the 
2000, 2001, and 2002 model years) is producing test results consistently 
below those from a full environmental test cell, EPA may review its 
approval of the simulation.

final reported test results for the SFTP composite (NMHC + 
NOX) and optional composite CO standards shall be computed by 
the following formulas.

(i) YWSFTP = 0.35(YFTP) + 0.37(YSC03) + 
0.28(YUS06)

    Where:
    (A) YWSFTP = Mass emissions per mile for a particular

the measured driving distance of the US06 test schedule.
    (ii) Composite (NMHC = NOX) + YWSFTP(NMHC) 
WSFTP(NOX)

Where:
    (A) YWSFTP(NMHC) = results of paragraph (c)(1)(i) of this 
section for NMHC.
    (B) YWSFTP(NOX) = results of paragraph 
(c)(1)(i) of this section for NOX.
    (2) When the test vehicle is not equipped with air conditioning, the 
relationship of paragraph (c)(1)(i) of this section is:
    (i) YWSFTP = 0.72(YFTP) + 
0.28(YUS06)

Where:
    (A) YWSFTP = Mass emissions per mile for a particular 
pollutant weighted in terms of the contributions from the FTP and US06 
schedules. Values of YWSFTP are obtained for each of the 
exhaust emissions of NMHC, NOX. and CO.
    (B) YFTP = Weighted mass emissions per mile (Ywm) based 
on the measured driving distance of the FTP test schedule.
    (C) YUS06 = Calculated mass emissions per mile based on 
the measured driving distance of the US06 test schedule.

[[Page 747]]

    (ii) Composite (NMHC + NOX) = YWSFTP(NMHC) + 
YWSFTP(NOX)

Where:
    (A) YWSFTP(NMHC) = results of paragraph (c)(2)(i) of this 
section for NMHC.
    (B) YWSFTP(NOX) = results of paragraph 
(c)(2)(i) of this section for NOX.
    (d) The NOX humidity correction factor for adjusting 
NOX test results to the environmental test cell air 
conditioning ambient condition of 100 grains of water/pound of dry air 
is:

KH (100) = 0.8825/[1-0.0047(H-75)]

Where:

H = measured test humidity in grains of water/pound of dry air.

    (a) The provisions of Sec.86.144-94 (b) and (c) are applicable to 
this section except that the NOX humidity correction factor 
of Sec.86.144-94(c)(7)(iv) must be modified when adjusting SC03

Sec.86.165-12  Air conditioning idle test procedure.

    (a) Applicability. This section describes procedures for determining 
air conditioning-related CO2 emissions from light-duty 
vehicles, light-duty trucks, and medium-duty passenger vehicles. The 
results of this test are used to qualify for air conditioning efficiency 
CO2 credits according to Sec.86.1866-12(c).
    (b) Overview. The test consists of a brief period to stabilize the 
vehicle at idle, followed by a ten-minute period at idle when 
CO2 emissions are measured without any air conditioning 
systems operating, followed by a ten-minute period at idle when 
CO2 emissions are measured with the air conditioning system 
operating. This test is designed to determine the air conditioning-
related CO2 emission value, in grams per minute. If engine 
stalling occurs during cycle operation, follow the provisions of Sec.
86.136-90 to restart the test. Measurement instruments must meet the 
specifications described in this subpart.
    (c) Test cell ambient conditions. (1) Ambient humidity within the 
test cell during all phases of the test sequence shall be controlled to 
an average of 40-60 grains of water/pound of dry air.
    (2) Ambient air temperature within the test cell during all phases 
of the test sequence shall be controlled to 73-80 [deg]F on average and 
75 5 [deg]F as an instantaneous measurement. Air 
temperature shall be recorded continuously at intervals of not more than 
30 seconds.
    (d) Test sequence. (1) Connect the vehicle exhaust system to the raw 
sampling location or dilution stage according to the provisions of this 
subpart. For dilution systems, dilute the exhaust as described in this 
subpart. Continuous sampling systems must meet the specifications 
provided in this subpart.
    (2) Test the vehicle in a fully warmed-up condition. If the vehicle 
has soaked for two hours or less since the last exhaust test element, 
preconditioning may consist of a 505 Cycle, 866 Cycle, US06, or SC03, as 
these terms are defined in Sec.86.1803-01, or a highway fuel economy 
test procedure, as defined in Sec.600.002-08 of this chapter. For soak 
periods longer than two hours, precondition the vehicle using one full 
Urban Dynamometer Driving Schedule. Ensure that the vehicle has 
stabilized at test cell ambient conditions such that the vehicle 
interior temperature is not substantially different from the external 
test cell temperature. Windows may be opened during preconditioning to 
achieve this stabilization.
    (3) Immediately after the preconditioning, turn off any cooling 
fans, if present, close the vehicle's hood, fully close all the 
vehicle's windows, ensure that all the vehicle's air conditioning 
systems are set to full off, start the CO2 sampling system, 
and then idle the vehicle for not less than 1 minute and not more than 5 
minutes to achieve normal and stable idle operation.
    (4) Measure and record the continuous CO2 concentration 
for 600 seconds. Measure the CO2 concentration continuously 
using raw or dilute sampling procedures. Multiply this concentration by 
the continuous (raw or dilute)

[[Page 749]]

flow rate at the emission sampling location to determine the 
CO2 flow rate. Calculate the CO2 cumulative flow 
rate continuously over the test interval. This cumulative value is the 
total mass of the emitted CO2. Alternatively, CO2 
may be measured and recorded using a constant velocity sampling system 
as described in Sec. Sec.86.106-96(a)(2) and 86.109.
    (5) Within 60 seconds after completing the measurement described in 
paragraph (d)(4) of this section, turn on the vehicle's air conditioning 
system. Set automatic air conditioning systems to a temperature 9 [deg]F 
(5 [deg]C) below the ambient temperature of the test cell. Set manual 
air conditioning systems to maximum cooling with recirculation turned 
off, except that recirculation shall be enabled if the air conditioning 
system automatically defaults to a recirculation mode when set to 
maximum cooling. Continue idling the vehicle while measuring and 
recording the continuous CO2 concentration for 600 seconds as 
described in paragraph (d)(4) of this section. Air conditioning systems 
with automatic temperature controls are finished with the test after 
this 600 second idle period. Manually controlled air conditioning 
systems must complete one additional idle period as described in 
paragraph (d)(6) of this section.
    (6) This paragraph (d)(6) applies only to manually controlled air 
conditioning systems. Within 60 seconds after completing the measurement 
described in paragraph (d)(5) of this section, leave the vehicle's air 
conditioning system on and set as described in paragraph (d)(5) of this 
section but set the fan speed to the lowest setting that continues to 
provide air flow. Recirculation shall be turned off except that if the 
system defaults to a recirculation mode when set to maximum cooling and 
maintains recirculation with the low fan speed, then recirculation shall 
continue to be enabled. After the fan speed has been set, continue 
idling the vehicle while measuring and recording the continuous 
CO2 concentration for a total of 600 seconds as described in 
paragraph (d)(4) of this section.
    (e) Calculations. (1) For the measurement with no air conditioning 
operation, calculate the CO2 emissions (in grams per minute) 
by dividing the total mass of CO2 from paragraph (d)(4) of 
this section by 10.0 (the duration in minutes for which CO2 
is measured). Round this result to the nearest tenth of a gram per 
minute.
    (2)(i) For the measurement with air conditioning in operation for 
automatic air conditioning systems, calculate the CO2 
emissions (in grams per minute) by dividing the total mass of 
CO2 from paragraph (d)(5) of this section by 10.0. Round this 
result to the nearest tenth of a gram per minute.
    (ii) For the measurement with air conditioning in operation for 
manually controlled air conditioning systems, calculate the 
CO2 emissions (in grams per minute) by summing the total mass 
of CO2 from paragraphs (d)(5) and (d)(6) of this section and 
dividing by 20.0. Round this result to the nearest tenth of a gram per 
minute.
    (3) Calculate the increased CO2 emissions due to air 
conditioning (in grams per minute) by subtracting the results of 
paragraph (e)(1) of this section from the results of paragraph (e)(2)(i) 
or (ii) of this section, whichever is applicable.
    (f) The Administrator may prescribe procedures other than those in 
this section for air conditioning systems and/or vehicles that may not 
be susceptible to satisfactory testing by the procedures and methods in 
this section. For example, the Administrator may prescribe alternative 
air conditioning system settings for systems with controls that are not 
able to meet the requirements in this section.

Sec.86.201  General applicability.

    (a) Vehicles are subject to cold temperature testing requirements as 
described in subpart S of this part and 40 CFR part 600.
    (b) Migration to 40 CFR parts 1065 and 1066. This subpart 
transitions to rely on the test procedure specifications in 40 CFR parts 
1065 and 1066 as follows:
    (1) Through model year 2021, manufacturers may use the test 
procedures specified in paragraph (c) or (d) of this section or, using 
good engineering judgement, elements of both. For any EPA testing before 
model year 2022, EPA will use the manufacturer's selected procedures for 
applying acceptable speed-tolerance criteria. For any other parameters, 
EPA may conduct testing using either of the specified procedures. As 
allowed under this part, manufacturers may use carryover data from 
previous model years to demonstrate compliance with emission standards, 
without regard to the provisions of this section.
    (2) For vehicles certified before model year 2022 to any of the Tier 
3 emission standards specified in subpart S of this part, manufacturers 
must determine overall driver accuracy based on driven cycle energy as 
described in 40 CFR 1066.425(j).
    (c) Interim procedures. Through model year 2021, manufacturers may 
certify vehicles based on data collected according to previously 
published cold temperature and intermediate temperature testing 
procedures.
    (d) Long-term procedures. Starting in model year 2022, perform 
testing to measure CO and NMHC emissions and determine fuel economy as 
described in 40 CFR part 1066; see especially 40 CFR 1066.710. We may 
approve the use of previously published cold temperature and 
intermediate temperature testing procedures for later model years as an 
alternative procedure under 40 CFR 1066.10(c). Perform intermediate 
temperature testing as follows:
    (1) For testing during ambient temperatures of less than 50 [deg]F 
(10 [deg]C), perform testing as described in 40 CFR part 1066, subpart 
H.
    (2) For testing at temperatures of 50 [deg]F (10 [deg]C) or higher, 
perform FTP testing as described in 40 CFR part 1066.
    (e) Section 86.213 describes special provisions related to test fuel 
specifications.

Sec.86.213  Fuel specifications.

    (a) Gasoline. Use a gasoline test fuel with ethanol (low-level blend 
only) or without ethanol as follows:
    (1) You must certify using service accumulation fuel and E10 test 
fuel as specified in Sec.86.113 for any vehicles required to use a 
low-level ethanol-gasoline blend test fuel for measuring exhaust 
emissions. You may use this test fuel any time earlier than we specify.
    (2) You may use the test fuel specified in this paragraph (a)(2) for 
vehicles that are not yet subject to exhaust testing with an ethanol-
blend test fuel under Sec.86.113. Manufacturers may certify based on 
this fuel using carryover data until testing with the ethanol-blend test 
fuel is required. The following specifications apply for gasoline test 
fuel without ethanol:

    Example: Section 86.411-78 applies to 1978 and subsequent model 
years until it is superseded. If a Sec.86.411-81 is promulgated it 
would take effect beginning with 1981; Sec.86.411-78 would apply to 
years 1978 through 1980.

    (b) A reference to a section without a year designation implies the 
appropriate model year.

    Example: When considering 1979 vehicles a reference to Sec.86.411 
implies Sec.86.411-79. However if no Sec.86.411-79 has been 
promulgated then Sec.86.411-78 is implied; See paragraph (a) of this 
section.



Sec.86.405-78  Measurement system.

    (a) This subpart and subpart F have been written using System 
International (SI) units. SI units will be used to determine compliance 
with these regulations. English equivalents have been indicated solely 
for the user's convenience.
    (b) [Reserved]



Sec.86.406-78  Introduction, structure of subpart, further information.

    (a) This subpart contains general provisions regulating the emission 
of air pollution from new motorcycles. Test procedures are found in 
subpart F.
    (b) Several discrete concepts are addressed:
    (1) Requirements. Sections 86.407 to 86.415.
    (2) Application for certification. Sections 86.416 and 86.417.
    (3) Test fleet selection. Sections 86.418 to 86.423.
    (4) Service accumulation, testing, maintenance, certification. 
Sections 86.424 to 86.439.
    (5) Administrative provisions. Sections 86.440 to 86.444.
    (c) The certification procedure to be followed depends upon the 
manufacturer's projected sales.

[[Page 754]]

    (1) New motorcycles, produced by a manufacturer whose projected U.S. 
sales of motorcycles is 10,000 or more units (for the model year in 
which certification is sought) shall demonstrate compliance with all 
general standards and all specific emission requirements before they can 
be sold in the United States. The manufacturer is required to submit an 
application with sales data, product information, required maintenance, 
testing and service accumulation procedures. The Administrator will 
select vehicle(s) which will represent the manufacturer's product line. 
The manufacturer is required to construct these vehicles to be 
representative of actual production. Service is accumulated and emission 
tests performed with data submitted to the Administrator. The 
Administrator may run his own tests to confirm the manufacturer's 
results. The Administrator will review the data and either grant or deny 
certification. If the manufacturer wishes to make changes to a certified 
vehicle, or to produce a new vehicle, the Administrator must be 
notified. The Administrator may require testing to demonstrate continued 
compliance with emission standards. Each vehicle must be labeled with 
tune up specifications and the purchaser must be supplied with 
maintenance instructions. Also, information on production vehicles must 
be supplied to the Administrator.
    (2) New motorcycles produced by a manufacturer whose projected U.S. 
sales of motorcycles is less than 10,000 units (for the model year in 
which certification is sought) shall meet both the general standards and 
specific emission requirements described in Sec. Sec.86.401 through 
86.417, Sec.86.425, Sec.86.437, and Sec. Sec.86.440 through 86.444 
of this subpart before they can be sold in the United States. The 
manufacturer is required to submit an application containing a statement 
that his vehicles conform to the applicable emission standards. The 
manufacturer is required to retain in his records, but not submit with 
the application, valid emission test data which support his statement. 
The Administrator will review the application and either grant or deny 
certification. Each vehicle must be labeled with tune up specifications 
and the purchaser must be supplied with maintenance instructions. Also, 
information on production vehicles must be supplied to the 
Administrator.
    (d) Manufacturers who are considering an application should contact: 
Director, Vehicle Programs and Compliance Division, Environmental 
Protection Agency, 2565 Plymouth Rd., Ann Arbor, Michigan 48105 and 
state whether he/she plans to certify for total sales of greater than or 
less than 10,000 vehicles for the applicable model year.

Sec.86.407-78  Certificate of conformity required.

    (a) General requirement. Every new motorcycle manufactured for sale, 
sold, offered for sale, introduced or delivered for introduction into 
commerce, or imported into the United States which is subject to any of 
the standards prescribed in this subpart is required to be covered by a 
certificate of conformity issued pursuant to this subpart, except as 
specified in paragraph (b) of this section, or otherwise exempted from 
this requirement.
    (b) Interim personal use exemption. An individual may manufacture 
one motorcycle for personal use without a certificate of conformity, 
subject to the following provisions:
    (1) The motorcycle may not be manufactured from a certified 
motorcycle. The motorcycle may not be manufactured from a partially 
complete motorcycle that is equivalent to a certified motorcycle, unless 
the emission controls are included in the final product. The motorcycle 
must be manufactured primarily from unassembled components, but may 
incorporate some preassembled components. For example, fully 
preassembled transmissions may be used.
    (2) The motorcycle may not be sold within five years of the date of 
final assembly.
    (3) No individual may manufacture more than one motorcycle during 
his or her lifetime under this exemption. This restriction applies with 
respect to

[[Page 755]]

the person who purchases the components and/or uses the motorcycle, 
rather than to the person(s) who actually assemble(s) the motorcycle.
    (4) This exemption may not be used to circumvent the requirements of 
paragraph (a) of this section or the requirements of the Clean Air Act. 
For example, this exemption would not cover a case in which an entity 
purchases a kit, assembles the kit, and then sells it to another party; 
this would be considered to be the sale of the complete motorcycle.
    (c) Interim display exemptions. Uncertified custom motorcycles that 
are used solely for display purposes are exempt from the standards 
provided they conform to the requirements of this paragraph (c). Unless 
a certificate of conformity has been received for such motorcycles, they 
may not be operated on the public streets or highways except for that 
operation incident and necessary to the display purpose.
    (1) No request is necessary for display motorcycles that will not be 
sold or leased.
    (2) The following requirements apply for exempting display 
motorcycles that will be sold or leased:
    (i) Manufacturers planning to sell motorcycles for display must 
notify EPA of their intent to do so before they sell any exempted 
motorcycles. They must also maintain sales records of exempted 
motorcycles for at least three years and make them available to EPA upon 
request.
    (ii) No manufacturer may sell or lease more than 24 exempted display 
motorcycles in any single calendar year.
    (iii) Anyone selling or leasing a motorcycle exempt under this 
paragraph (c) must ensure that the buyer or lessee agrees to comply with 
the display exemption terms in the regulations.
    (3) Each motorcycle exempt under this paragraph (c) must include a 
label that identifies the manufacturer and includes the following 
statement: THIS MOTORCYCLE IS EXEMPT FROM EPA EMISSION REQUIREMENTS. ITS 
USE ON PUBLIC ROADS IS LIMITED PURSUANT TO 40 CFR 86.407-78(c). EPA may 
allow manufacturers to locate the label in a location where it is 
obscured or hidden by a readily removable component. For example, EPA 
may allow the label to be located under the seat.
    (4) As described in 40 CFR part 1051, motorcycles that are not 
considered to be motor vehicles according to 40 CFR 85.1703(a) may be 
exempt under this paragraph (c) from the standards and requirements of 
40 CFR part 1051. Such motorcycles shall be combined with the 
manufacturer's highway motorcycles with respect to the sales restriction 
described in paragraph (c)(2)(ii) of this section.
    (5) This exemption may not be used to circumvent the requirements of 
paragraph (a) of this section or the requirements of the Clean Air Act.

[69 FR 2435, Jan. 15, 2004]



Sec.86.408-78  General standards; increase in emissions;
unsafe conditions.

    (a) Any system installed on or incorporated in a new motorcycle to 
enable such vehicle to conform to standards imposed by this subpart:
    (1) Shall not in its operation or function cause the emission into 
the ambient air of any noxious or toxic substance that would not be 
emitted in the operation of such vehicle without such system, except as 
specifically permitted by regulation; and
    (2) Shall not in its operation, function, or malfunction result in 
any unsafe condition endangering the motorcycle, its rider(s), or 
persons or property in close proximity to the vehicle.
    (b) Every manufacturer of new motorcycles subject to any of the 
standards imposed by this subpart shall, prior to taking any of the 
actions specified in section 203(a)(1) of the Act, test or cause to be 
tested motorcycles in accordance with good engineering practice to 
ascertain that such test vehicles will meet the requirements of this 
section for the useful life of the vehicle.

    Effective Date Note: At 86 FR 34366, June 29, 2021, Sec.86.408-78 
was amended, effective July 29, 2021.



Sec.86.409-78  Defeat devices, prohibition.

    (a) No motorcycle shall be equipped with a defeat device.
    (b) Defeat device means any element of design which:

parameter for the purpose of activating, modulating, delaying, or 
deactivating the operation of any part of the emission control system.
    (b) New motorcycles produced by a small-volume manufacturer (as 
defined in Sec.86.410(e)) or by any other manufacturer whose projected 
sales in the United States is less than 10,000 units (for the model year 
in which certification is sought) are covered by the following:
    (1) All the information that would otherwise be required to be 
submitted to EPA under paragraph (a)(2) of this section must be made a 
part of the manufacturer's records, except there is no requirement to 
submit the information to the Administrator or receive approval from the 
Administrator.
    (2) Section 86.437 details the statements that these manufacturers 
are required to provide to the Administrator.
    (c) For the purpose of determining applicability of paragraphs (a) 
or (b) of this section, where there is more than one importer or 
distributor of vehicles manufactured by the same person, the projected 
sales shall be the aggregate of the projected sales of those vehicles by 
such importers or distributors.
    (d)(1) The Administrator has determined that the following 
certification procedure may be used to demonstrate

[[Page 761]]

compliance for each motorcycle engine family for which certification is 
sought. Manufacturers may follow these procedures at their option.
    (i) The manufacturer shall satisfy all applicable requirements of 
part 86 necessary to demonstrate compliance with the standards for each 
class of new motorcycles for which certification is sought.
    (ii) As specifically allowed by the Administrator the manufacturer 
shall assume the responsibility for part or all of the decisions

by the Administrator.
    (v) At the Administrator's request, the manufacturer shall notify 
the Administrator of the status of the certification program including 
projected schedules of those significant accomplishments specified by 
the Administrator.
    (vi) The manufacturer shall permit the Administrator to inspect any 
facilities, records, and vehicles from which data were obtained under 
the abbreviated certification review procedure.
    (vii) Upon completing all applicable requirements of part 86 the 
manufacturer shall submit a separate application for a certificate of 
conformity for each class of new motorcycles for which certification is 
sought. Such application shall be made in writing to the Administrator 
by the manufacturer.
    (A) The Administrator may approve or disapprove in whole or in part 
an application for certification according to the procedures specified 
in Sec.86.417-78(b).
    (B) If, after a review of the application for certification, test 
reports and data submitted by the manufacturer, data obtained during an 
inspection, and any other pertinent data or information, the 
Administrator determines that a test vehicle(s) has not met the 
requirements of the Act and the applicable subpart, he will notify the 
manufacturer in writing and set forth the reason(s) for the 
determination.
    (2) Those families which are not following the procedure described 
in paragraph (d)(1) of this section will follow the procedure in this 
subpart with the exception of paragraph (d)(1) of this section.
    (e) The Administrator may require that an engine family previously 
allowed to be subjected to the abbreviated certification review 
procedure be transferred to the complete review procedure.
    (f) Upon request, the Administrator may allow a manufacturer to use 
alternate certification procedures that are equivalent in terms of 
demonstrating compliance with the requirements of this part.

Sec.86.417-78  Approval of application for certification.

    (a) After a review of the application for certification and any 
other information which the Administrator may require, the Administrator 
may approve the application and select a test fleet as appropriate.
    (b) The Administrator may disapprove in whole or in part an 
application for certification for reasons including incompleteness, 
inaccuracy, inappropriate proposed distance accumulation procedures, 
maintenance, test equipment, label content or location, fuel or 
lubricant, and incorporation of defeat devices in vehicles described by 
the application. Where any part of an application is rejected the 
Administrator shall notify the manufacturer in writing and set forth the 
reasons for such rejection. The manufacturer may request a hearing under 
Sec.86.443.

Sec.86.419-2006  Engine displacement, motorcycle classes.

    (a)(1) Engine displacement shall be calculated using nominal engine 
values and rounded to the nearest whole cubic centimeter.
    (2) For rotary engines, displacement means the maximum volume of a 
combustion chamber between two rotor tip seals, minus the minimum volume 
of the combustion chamber between those two rotor tip seals, times three 
times the number of rotors, according to the following formula:

cc = (max. chamber volume - min. chamber volume) x 3 x no. of rotors

    (b) Motorcycles will be divided into classes based on engine 
displacement.
    (1) Class I--0 to 169 cc (0 to 10.4 cu. in.).
    (i) Class I motorcycles with engine displacement less than 50 cc 
comprise the Class I-A subclass.
    (ii) Class I motorcycles with engine displacement 50 cc or higher 
comprise the Class I-B subclass.
    (2) Class II--170 to 279 cc (10.4 to 17.1 cu. in.).
    (3) Class III--280 cc and over (17.1 cu. in. and over).
    (c) At the manufacturer's option, a vehicle described in an 
application for certification may be placed in a higher class (larger 
displacement). All procedures for the higher class must then be complied 
with and compliance with emission standards will be determined on the 
basis of engine displacement.

2006 was removed, effective July 29, 2021.



Sec.86.420-78  Engine families.

    (a) The vehicles covered in the application will be divided into 
groupings whose engines are expected to have similar emission 
characteristics throughout their useful life. Each group of engines with 
similar emission characteristics shall be defined as a separate engine 
family.
    (b) Reciprocating families. To be classed in the same engine family, 
reciprocating engines must be identical in all of the following 
applicable respects:
    (1) The combustion cycle.
    (2) The cooling mechanism.
    (3) The cylinder configuration (inline, vee, opposed, bore spacings, 
etc.).

composition.
    (8) The thermal reactor characteristics.
    (9) The number of carburetors.
    (10) The prechamber characteristics.
    (c) At the manufacturer's option, reciprocating engines identical in 
all the respects listed in paragraph (b) of this section may be further 
divided into different engine families if the Administrator determines 
that they may be expected to have different emission characteristics. 
This determination will be based upon a consideration of features such 
as:
    (1) The bore and stroke.
    (2) The combustion chamber configuration.
    (3) The intake and exhaust timing method of actuation (poppet valve, 
reed valve, rotary valve, etc.).
    (4) The intake and exhaust valve or port sizes, as applicable.
    (5) The fuel system.
    (6) The exhaust system.
    (d) Rotary families. To be classed in the same engine family, rotary 
combustion cycle engines must be identical in all of the following 
applicable respects:
    (1) The major axis of the epitrochoidal curve.
    (2) The minor axis of the epitrochoidal curve.
    (3) The generating radius of the epitrochoidal curve.
    (4) The cooling mechanism.
    (5) The number of rotors.
    (6) The engine displacement class, Sec.86.419.
    (7) The method of air aspiration.
    (8) The number of catalytic converters, location, volume and 
composition.
    (9) The thermal reactor characteristics.
    (10) The number of carburetors.
    (11) The prechamber characteristics.
    (e) At the manufacturer's option, rotary combustion cycle engines 
identical in all the respects listed in paragraph (d) of this section, 
may be further divided into different engine families if the 
Administrator determines that they may be expected to have different 
emission characteristics. This determination will be based upon a 
consideration of features, such as:
    (1) The width of the rotor housing.
    (2) The type and location of intake port (side, peripheral, 
combination, etc.).
    (3) The number of spark plugs per rotor.
    (4) The fuel system.
    (5) The exhaust system.
    (f) Where engines are of a type which cannot be divided into engine 
families based upon the criteria listed in paragraphs (b) and (d) of 
this section, the Administrator will establish families of those engines 
based upon the features most related to their emission characteristics.

Sec.86.421-78  Test fleet.

    (a) A test vehicle will be selected by the Administrator to 
represent each engine-displacement-system combination. The configuration 
(engine calibration, transmission, drive ratio, mass, options, etc.) in 
the manufacturer's application which the Administrator believes has the 
greatest probability of exceeding the standards will be selected.
    (b) At the manufacturer's option, the Administrator will only select 
one vehicle to represent each engine family where the total projected 
annual sales for that family are less than 5,000 vehicles.
    (c) A manufacturer may elect to operate and test additional vehicles 
which are identical to those selected by the Administrator. Written 
notice of a commitment to operate and test additional vehicles shall be 
given to the Administrator prior to the start of testing and not later 
than 30 days following notification of the test fleet selection. The 
results of tests performed by the manufacturer will be combined to 
determine deterioration factors. Each vehicle must meet applicable 
standards when tested by the Administrator and when those results are 
projected to the useful life.
    (d) In lieu of testing a test vehicle and submitting data therefore, 
a manufacturer may, with the prior written approval of the 
Administrator, submit

[[Page 764]]

exhaust emission data on a similar vehicle for which certification has 
previously been obtained or for which all applicable data has previously 
been submitted.



Sec.86.422-78  Administrator's fleet.

    The Administrator may require additional test vehicles identical in 
all material respects to vehicles selected in accordance with Sec.
86.421. The number of vehicles selected shall not increase the size of 
the test fleet by more than 20 percent or one vehicle, whichever is 
greater.



Sec.86.423-78  Test vehicles.

    (a)(1) Before beginning service accumulation on a test vehicle, the 
manufacturer may perform a zero-kilometer exhaust emission test.
    (2) If such a test is performed, the data shall be submitted to the 
Administrator when the application is submitted.
    (3) Zero-kilometer test results shall not be included in the 
determination of deterioration factors.
    (b) Once a manufacturer begins to operate a test vehicle, as 
indicated by compliance with paragraph (a) of this section, the data 
from the vehicle will be used, unless specified otherwise by the 
Administrator. Discontinuation of a vehicle shall be allowed only with 
the written consent of the Administrator.
    (c) Test vehicles shall be calibrated at zero kilometres within the 
production tolerances applicable to the manufacturer's specifications.
    (d) The Administrator may disqualify a vehicle which receives 
assembly line operations and adjustments which will not be performed on 
production vehicles.

[42 FR 1126, Jan. 5, 1977, as amended at 49 FR 48138, Dec. 10, 1984]



Sec.86.425-78  Test procedures.

    (a) Motorcycle emission test procedures are found in subpart F.
    (b) The Administrator may prescribe emission test procedures for any 
motorcycle which he determines is not susceptible to satisfactory 
testing by the procedures set forth in subpart F.
    (c) Testing of any type with respect to any test vehicle other than 
that specified in this subpart and subpart F is not allowed except as 
specifically authorized by the Administrator.



Sec.86.426-78  Service accumulation.

    (a) The procedure for service accumulation will be the Durability 
Driving Schedule as specified in appendix IV to this part. A modified 
procedure may also be used if approved in advance by the Administrator. 
Except with the advance approval of the Administrator, all vehicles will 
accumulate distance at a measured curb mass which is within 5 kg (11.0 
lb) of the loaded vehicle mass specified by the Administrator.
    (b) During service accumulation, vehicles shall not be operated for 
more than 12 hours during an operating sequence. Engine shutdowns are 
permitted during the operating sequence, but the periods of shutdown are 
not included in the 12 hour total. Following each operating sequence, 
the vehicle shall soak, without operation, for a minimum of 8 hours. 
During soak periods, the vehicle shall be exposed to normal outside 
ambient temperatures and humidity conditions unless vehicle maintenance 
or servicing is being performed.
    (c) The manufacturer's recommended shifting procedure will be used 
for laps 1 through 10. Lap 11 shifts (W.O.T. accelerations) must be 
conducted at the manufacturer's recommended maximum safe engine speed.

Sec.86.427-78  Emission tests.

    (a)(1) Each test vehicle shall be driven with all emission control 
systems installed and operating for the following total test distances, 
or for such lesser distances as the Administrator may agree to as 
meeting the objectives of this procedure. (See Sec.86.419 for class 
explanation.)

III............................        15,000         3,500            4
------------------------------------------------------------------------

    (2) A zero kilometer emission test may be performed prior to the 
beginning of service accumulation.

[[Page 765]]

    (b) All vehicles shall undergo at least four emission tests; one at 
the minimum test distance, one before and one after periodic 
maintenance, and one at the total test distance. If no maintenance is 
scheduled, then at least two tests will be performed, at equal 
intervals, between the minimum and total test distances. Additional 
tests may be performed; such tests must be at equal intervals and 
approved by the Administrator prior to starting service accumulation.
    (c) Where the Administrator agrees to a lesser distance for service 
accumulation, he may modify the maintenance provisions of this subpart.
    (d) All tests required by this subpart must be conducted at an 
accumulated distance within 250 kilometers (155 mi) of the nominal 
distance at each test point.
    (e)(1) If a manufacturer conducts multiple tests at any test point 
at which the data are intended to be used in the calculation of the 
deterioration factor, the number of tests must be the same at each point 
and may not exceed three valid tests unless the manufacturer chooses to 
average the test results.
    (2) If the manufacturer chooses to average the test results at a 
test point, he may conduct more tests than the minimum number of tests 
conducted at any other test point.
    The results of the multiple tests shall be averaged to create a 
single value which is the test point value used in the deterioration 
factor calculation specified in Sec.86.432-78.
    (3) When using this option to generate data for a particular test 
point, the manufacturer must include in the average all valid test data 
generated at that test point.
    (4) The manufacturer shall follow the same procedure for all exhaust 
pollutants.
    (5) The test results obtained from the emission tests performed 
before and after maintenance affecting emissions shall not be averaged.
    (f) The Administrator may require that any one or more of the test 
vehicles be submitted to him, at such places as he may designate, for 
the purpose of conducting emissions tests. The Administrator may specify 
that he will conduct such testing at the manufacturer's facility, in 
which case instrumentation and equipment specified by the Administrator 
shall be made available by the manufacturer for test operations. Any 
testing conducted at a manufacturer's facility pursuant to this 
paragraph shall be scheduled by the manufacturer as promptly as 
possible.
    (g) Whenever the Administrator conducts a test on a test vehicle, 
the results of that test, unless subsequently invalidated by the 
Administrator, shall comprise the data for the vehicle at that 
prescribed test point and the manufacturer's data for that prescribed 
test point shall not be used in determining compliance with emission 
standards.

Sec.86.428-80  Maintenance, scheduled; test vehicles.

    (a) Periodic maintenance on the engine, emission control system, and 
fuel system of test vehicles shall be scheduled for performance at the 
same distance intervals that will be specified in the manufacturer's 
maintenance instructions furnished to the ultimate purchaser. Such 
maintenance shall be performed only under the following provisions.
    (b) Periodic major engine tune-ups to the manufacturer's 
specifications may be performed no more frequently than as follows nor 
may any tune-up be performed within 1000 km prior to the official test.

------------------------------------------------------------------------

------------------------------------------------------------------------
I..........................................................        3,000
II.........................................................        3,000
III........................................................        4,000
------------------------------------------------------------------------

    (c) A scheduled major engine tune-up shall be restricted to items 
listed below and shall be conducted in a manner consistent with service 
instructions and specifications provided by the manufacturer for use by 
customer service personnel. The following items may be inspected, 
replaced, cleaned,

[[Page 766]]

adjusted, and/or serviced as required: (1) Breaker points, timing, (2) 
idle speed and idle air/fuel mixture, (3) valve lash, (4) engine bolt 
torque, and (5) spark plugs.
    (d) The Administrator will specify the ignition timing, idle air 
fuel mixture and other fuel system adjustments to be used at each tune-
up. The settings selected will be those the Administrator deems 
appropriate within the physically available range.
    (e) Periodic change of engine and transmission oil, and change or 
service of oil, air, and fuel filters will be allowed at the same 
distance intervals that will be specified in the manufacturer's 
maintenance instructions.
    (f) Requests for authorization of periodic maintenance of emission 
control related components not specifically authorized to be maintained 
by this section, and for anticipated maintenance (see Sec.86.428), 
must be made prior to the beginning of distance accumulation. The 
Administrator will approve the performance of such maintenance if the 
manufacturer makes a satisfactory showing that the maintenance will be 
performed on vehicles in use and that the maintenance is reasonable and 
necessary.
    (1) The EGR system may be serviced a maximum of two times during the 
durability service accumulation if failure of the EGR system activates 
an audible and/or visual signal approved by the Administrator which 
alerts the vehicle operator to the need for EGR system maintenance, or 
if the need for periodic maintenance of the EGR system is overtly 
signalled to the vehicle operator by an appropriate means, e.g., an 
indicator light or significantly reduced driveability performance.
    (2) The catalytic converter may be serviced only once during the 
durability service accumulation if failure of the catalytic converter 
activates an audible and/or visual signal approved by the Administrator 
which alerts the vehicle operator to the need for catalytic converter 
maintenance, or if the need for periodic maintenance of the catalytic 
converter is overtly signalled to the vehicle operator by an appropriate 
means, e.g., an indicator light or significantly reduced driveability 
performance.
    (g) Certain engine components may require maintenance which, by its 
nature, cannot be scheduled for periodic intervals, but which the 
manufacturer believes will be necessary. For example, piston and 
cylinder replacement caused by piston seizure which results in the 
vehicle being inoperative; or in the case of two-stroke engines, 
decarbonization, the need for which is signalled to the vehicle operator 
by significantly reduce driveability performance. Such maintenance is 
designated anticipated maintenance. Anticipated maintenance must be 
identified by the manufacturer and approved as being appropriate by the 
Administrator prior to the start of service accumulation. The 
approximate distance at which the need for anticipated maintenance may 
arise must be specified in the application for certification.
    (h) Complete emission tests (see subpart F) are required, unless 
waived by the Administrator, before and after any vehicle maintenance 
which may reasonably be expected to affect emissions.



Sec.86.429-78  Maintenance, unscheduled; test vehicles.

    (a) Any unscheduled engine, emission control system, or fuel system 
adjustment, repair, removal, disassembly, cleaning, or replacement on 
vehicles shall be performed only with the advance approval of the 
Administrator.
    (1) In the case of unscheduled maintenance, such approval will be 
given if the Administrator:
    (i) Has made a preliminary determination that part failure or system 
malfunction, or the repair of such failure or malfunction, does not 
render the vehicle unrepresentative of vehicles in use, and does not 
require direct access to the combustion chamber, except for spark plug, 
fuel injection component, or removable prechamber removal or 
replacement; and
    (ii) Has made a determination that the need for maintenance or 
repairs is indicated by an overt indication of malfunction such as 
persistent misfire, vehicle stall, overheating, fluid leakage, loss of 
oil pressure, or charge indicator warning.
    (2) Emission measurements may not be used as a means of determining 
the

[[Page 767]]

need for unscheduled maintenance under paragraph (a)(1)(i) of this 
section.
    (b) Repairs to vehicle components of test vehicles, other than the 
engine, emission control system, or fuel system, shall be performed only 
as a result of part failure, vehicle system malfunction, or with the 
advance approval of the Administrator.
    (c) The Administrator shall be given the opportunity to verify the 
extent of an overt indication of part failure and/or vehicle malfunction 
(e.g., misfire, stall), or an activation of an audible and/or visual 
signal, prior to the performance of any maintenance to which such overt 
indication or signal is relevant under the provisions of this section.
    (d) Equipment, instruments, or tools may not be used to identify 
malfunctioning, maladjusted, or defective engine components unless the 
same or equivalent equipment, instruments, or tools will be available at 
dealerships and other service outlets and
    (1) Are used in conjunction with scheduled maintenance on such 
components, and
    (2) Are used subsequent to the identification of a vehicle or engine 
malfunction, as provided in paragraph (a)(1) of this section for 
durability or emission data vehicles, or
    (3) Unless specifically authorized by the Administrator.
    (e) If the Administrator determines that part failure or system 
malfunction occurrence and/or repair rendered the vehicle 
unrepresentative of vehicles in use, the vehicle shall not be used as a 
test vehicle.
    (f) Complete emission tests are required, unless waived by the 
Administrator, before and after any vehicle maintenance which may 
reasonably be expected to affect emissions.



Sec.86.430-78  Vehicle failure.

    Any test vehicle which incurs major mechanical failure necessitating 
disassembly of the engine shall not be used as a test vehicle. This 
prohibition does not apply to failures occurring after the completion of 
all required tests at the total test distance.

[49 FR 48139, Dec. 10, 1984]



Sec.86.431-78  Data submission.

    (a) Data from all tests (including voided tests) performed by a 
manufacturer with total projected sales in excess of 10,000 vehicles 
shall be included in the application.
    (b) The manufacturer shall furnish to the Administrator explanation 
for voiding any test. The Administrator will determine if voiding the 
test was appropriate based upon the explanation given by the 
manufacturer. If the Administrator determines that voiding the test was 
not appropriate, the Administrator may require that the data from that 
test be used in the calculation of the deterioration factor for 
emissions.
    (c) When unscheduled or anticipated maintenance is performed, a 
complete record of all pertinent maintenance, including the malfunction 
diagnosis made, the corrective action taken, and the test data obtained 
shall be included in the application.
    (d) A complete record of all maintenance shall be supplied.
    (e) Measure CO2, N2O, and CH4 as 
described in this paragraph (e) with each zero kilometer certification 
test (if one is conducted) and with each test conducted at the 
applicable minimum test distance as defined in Sec.86.427-78. Use the 
analytical equipment and procedures specified in 40 CFR part 1065 as 
needed to measure N2O and CH4. Report these values 
in your application for certification. The requirements of this 
paragraph (e) apply starting with model year 2011 for CO2 and 
2012 for CH4. The requirements of this paragraph (e) related 
to N2O emissions apply for engine families that depend on 
NOX aftertreatment to meet emission standards starting with 
model year 2013. Small-volume manufacturers (as defined in Sec.86.410-
2006(e)) may omit measurement of N2O and CH4; 
other manufacturers may provide appropriate data and/or information and 
omit measurement of N2O and CH4 as described in 40 
CFR 1065.5. Use the same measurement methods as for your other results 
to report a single value for CO2, N2O, and 
CH4. Round the final values as follows:
    (1) Round CO2 to the nearest 1 g/km.
    (2) Round N2O to the nearest 0.001 g/km.

[[Page 768]]

    (3) Round CH4 to the nearest 0.001 g/km.

Sec.86.432-78  Deterioration factor.

    (a) Deterioration factors shall be developed for each test vehicle 
from the emission test results. A separate factor shall be developed for 
each pollutant. The applicable data to be used in calculating these 
factors are:
    (1) The results from all valid tests conducted by the manufacturer 
or Administrator at scheduled test intervals.
    (2) The results from tests conducted before and after scheduled 
maintenance unless specifically excluded by the Administrator.
    (3) The results from tests conducted before and after unscheduled 
maintenance, if approval of the maintenance by the Administrator was 
conditioned on the data being used in the deterioration factor 
calculation.
    (b) Emission results which are less than 0.10 g/km shall be 
considered to be 0.10 g/km for purposes of this section.
    (c) Test results for each pollutant shall be plotted as a function 
of the service accumulated at the start of the emission test, rounded to 
the nearest kilometre. These results shall be correlated to a straight 
line, fit by the method of least squares.
    (d) An exhaust emission deterioration factor will be calculated by 
dividing the predicted emissions at the useful life distance by the 
predicted emissions at the total test distance. Predicted emissions are 
obtained from the correlation developed in paragraph (c) of this 
section.


Factor = Predicted total distance emissions / Predicted total test 
distance emissions.


These interpolated and extrapolated values shall be carried out to four 
places to the right of the decimal point before dividing one by the 
other to determine the deterioration factor. The results shall be 
rounded to three places to the right of the decimal point.
    (e) Deterioration factors computed to be less than 1.000 shall be 
1.000.
    (f)(1) The manufacturer has the option of applying an outlier test 
point procedure to completed durability data within its certification 
testing program for a given model year.
    (2) The outlier procedure will be specified by the Administrator.
    (3) For any pollutant, durability-data test points that are 
identified as outliers shall not be included in the determination of 
deterioration factors if the manufacturer has elected this option.
    (4) The manufacturer shall specify to the Administrator, before the 
certification of the first engine family for that model year, if it 
intends to use the outlier procedure.
    (5) The manufacturer may not change procedures after the first 
engine family of the model year is certified.
    (6) Where the manufacturer chooses to apply the outlier procedure to 
a data set containing data which were averaged under Sec.86.427-78(e), 
the outlier procedure shall be completed before averaging the data.

Sec.86.434-78  Testing by the Administrator.

    (a) At the conclusion of service accumulation, and after emission 
tests for deterioration, the Administrator may require confirmatory 
testing. The Administrator will designate where such testing shall be 
performed.
    (b) The manufacturer may request a retest. The results of the retest 
will be used to determine compliance.
    (c) If the emission results exceed the standard, certification will 
be denied.

[49 FR 48139, Dec. 10, 1984]



Sec.86.435-78  Extrapolated emission values.

    (a) If the deterioration factor lines are below the standards 
between the minimum test distance and the useful life, or if all points 
used to generate the lines are below the standards, predicted useful 
life emissions shall be calculated. If not, the manufacturers may elect 
to withdraw the vehicle or accumulate additional service.
    (b) The emission test results of each pollutant obtained from the 
half life

[[Page 769]]

test will be multiplied by the appropriate deterioration factors to 
determine useful life emissions.
    (1) If the useful life emissions are below the standards, 
certification will be granted.
    (2) If any of the useful life emissions exceed the emission 
standards, the vehicle must (if not withdrawn) accumulate distance to 
the useful life.

was amended, effective July 29, 2021.



Sec.86.436-78  Additional service accumulation.

    (a) Additional service up to the useful life will be accumulated 
under the same conditions as the initial service accumulation.
    (b) New deterioration lines will be generated using all applicable 
test points up to the useful life. The same procedures for determining 
the original deterioration lines will be used.
    (c) [Reserved]
    (d) To qualify for certification:
    (1) The full life emission test results must be below the standards, 
and
    (2) The deterioration line must be below the standard at the minimum 
test distance and the useful life, or all points used to generate the 
line, must be below the standard.
    (e) If the vehicle is unable to complete the total distance due to 
engine mechanical failure, certification will be granted if:
    (1) The mechanical failure was anticipated, Sec.86.428, and
    (2) A new deterioration line calculated using the procedure 
described in Sec.86.436-78(b) is below the standard at the minimum 
test distance and at the useful life, and,
    (3) The results of the half life emission tests, when adjusted by 
the new deterioration factors, are below the standards.

    (b) The Administrator may allow reduced testing.

[[Page 771]]



Sec.86.439-78  Alternative procedure for notification of additions
and changes.

    (a)(1) A manufacturer may, in lieu of notifying the Administrator in 
advance of an addition of a vehicle or a change in a vehicle under Sec.
86.438-78, notify the Administrator concurrently with the addition of a 
vehicle or the making of a change in a vehicle if the manufacturer 
determines that following the change all vehicles affected by the 
addition or change will still meet the applicable emission standards.
    (2) Such notification shall include a full description of the 
addition or change and any supporting documentation the manufacturer may 
include to support the manufacturer's determination that the addition or

Sec.86.441-78  Right of entry.

    (a) Any manufacturer who has applied for certification of a new 
motorcycle subject to certification tests under this subpart shall admit 
or cause to be admitted any EPA Enforcement Officer during operating 
hours on presentation of any credentials to any of the following:
    (1) Any facility where any such tests or any procedures or 
activities connected with such tests are or were performed.
    (2) Any facility where any new motorcycle which is being, was or is 
to be tested is present.
    (3) Any facility where any construction process or assembly process 
used in the modification or build-up of such a vehicle into a 
certification vehicle is taking place or has taken place.
    (4) Any facility where any record or other document relating to any 
of the above is located.
    (b) Upon admission to any facility referred to in paragraph (c)(1) 
of this section, any EPA Enforcement Officer shall be allowed:
    (1) To inspect and monitor any part or aspect of such procedures, 
activities, and testing facilities, including, but not limited to, 
monitoring vehicle preconditioning, emissions tests and service 
accumulation, maintenance, and vehicle soak and storage procedures; and 
to verify correlation or calibration of test equipment;
    (2) To inspect and make copies of any such records, designs, or 
other documents; and
    (3) To inspect and/or photograph any part or aspect of any such 
certification vehicle and any components to be used in the construction 
thereof.
    (c) In order to allow the Administrator to determine whether or not 
production motorcycles conform in all material respects to the design 
specifications which applied to those vehicles described in the 
application for

[[Page 773]]

certification for which a certificate of conformity has been issued and 
to standards prescribed under section 202 of the Act, any manufacturer 
shall admit any EPA Enforcement Officer on presentation of credentials 
to both:
    (1) Any facility where any document design, or procedure relating to 
the translation of the design and construction of engines and emission 
related components described in the application for certification or 
used for certification testing into production vehicles is located or 
carried on; and
    (2) Any facility where any motorcycles to be introduced into 
commerce are manufactured or assembled.
    (d) On admission to any such facility referred to in paragraph 
(c)(3) of this section, any EPA Enforcement Officer shall be allowed:
    (1) To inspect and monitor any aspects of such manufacture or 
assembly and other procedures;
    (2) To inspect and make copies of any such records, documents or 
designs; and
    (3) To inspect and photograph any part or aspect of any such new 
motorcycles and any component used in the assembly thereof that are 
reasonably related to the purpose of his entry.
    (e) Any EPA Enforcement Officer shall be furnished by those in 
charge of a facility being inspected with such reasonable assistance as 
he may request to help him discharge any function listed in this 
paragraph. Each applicant for or recipient of certification is required 
to cause those in charge of a facility operated for its benefit to 
furnish such reasonable assistance without charge to EPA whether or not 
the applicant controls the facility.
    (f) The duty to admit or cause to be admitted any EPA Enforcement 
Officer applies whether or not the applicant owns or controls the 
facility in question and applies both to domestic and to foreign 
manufacturers and facilities. EPA will not attempt to make any 
inspections which it has been informed that local law forbids. However, 
if local law makes it impossible to do what is necessary to insure the 
accuracy of data generated at a facility, no informed judgment that a 
vehicle or engine is certifiable or is covered by a certificate can 
properly be based on that data. It is the responsibility of the 
manufacturer to locate its testing and manufacturing facilities in 
jurisdictions where this situation will not arise.
    (g) For purposes of this section:
    (1) Presentation of credentials shall mean display of the document 
designating a person as an EPA Enforcement Officer.
    (2) Where vehicle, component, or engine storage areas or facilities 
are concerned, operating hours shall mean all times during which 
personnel other than custodial personnel are at work in the vicinity of 
the area or facility and have access to it.
    (3) Where facilities or areas other than those covered by paragraph 
(g)(2) of this section are concerned, operating hours shall mean all 
times during which an assembly line is in operation or all times during 
which testing, maintenance, service accumulation, production or 
compilation of records, or any other procedure or activity related to 
certification testing, to translation of designs from the test stage to 
the production stage, or to vehicle manufacture or assembly is being 
carried out in a facility.
    (4) Reasonable assistance includes, but is not limited to, clerical, 
copying, interpretation and translation services, the making available 
on request of personnel of the facility being inspected during their 
working hours to inform the EPA Enforcement Officer of how the facility 
operates and to answer his questions, and the performance on request of 
emissions tests on any vehicle which is being, has been, or will be used 
for certification testing. Such tests shall be nondestructive, but may 
require appropriate service accumulation. A manufacturer may be 
compelled to cause the personal appearance of any employee at such a 
facility before an EPA Enforcement Officer by written request for his 
appearance, signed by the Assistant Administrator for Enforcement, 
served on the manufacturer. Any such employee who has been instructed by 
the manufacturer to appear will be entitled to be accompanied, 
represented, and advised by counsel. No counsel who accompanies, 
represents, or advises an employee compelled to appear may accompany,

[[Page 774]]

represent, or advise any other person in the investigation.
    (5) Any entry without 24 hours prior written or oral notification to 
the affected manufacturer shall be authorized in writing by the 
Assistant Administrator for Enforcement.



Sec.86.442-78  Denial, revocation, or suspension of certification.

    (a) Notwithstanding the fact that any certification vehicle(s) may 
comply with other provisions of this subpart, the Administrator may 
withhold or deny the issuance of a certificate of conformity (or suspend 
or revoke any such certificate which has been issued) with respect to 
any such vehicle(s) if:
    (1) The manufacturer submits false or incomplete information in his 
application for certification thereof; or
    (2) The manufacturer renders inaccurate or invalid any test data 
which he submits pertaining thereto or otherwise circumvents the intent 
of the Act or of this subpart with respect to such vehicle; or
    (3) Any EPA Enforcement Officer is denied access on the terms 
specified in Sec.86.441 to any facility or portion thereof which 
contains any of the following:
    (i) The vehicle, or
    (ii) Any components used or considered for use in its modification 
or build-up into a certification vehicle, or
    (iii) Any production vehicle which is or will be claimed by the 
manufacturer to be covered by the certificate, or
    (iv) Any step in the construction of a vehicle described in 
paragraph (c) of this section, or
    (v) Any records, documents, reports, or histories required by this 
part to be kept concerning any of the above.
    (4) Any EPA Enforcement Officer is denied ``reasonable assistance'' 
(as defined in Sec.86.444) in examining any of the items listed in 
paragraph (a)(1)(iii) of this section.
    (b) The sanctions of withholding, denying, revoking, or suspending 
of a certificate may be imposed for the reasons in paragraph (a) of this 
section only when the infraction is substantial.
    (c) In any case in which a manufacturer knowingly submits false or 
inaccurate information, or knowingly renders inaccurate or invalid any 
test data, or commits any fraudulent acts and such acts contribute 
substantially to the Administrator's decision to issue a certificate of 
conformity, the Administrator may deem such certificate void ab initio.
    (d) In any case in which certification of a vehicle is proposed to 
be withheld, denied, revoked, or suspended under paragraph (a) (3) or 
(4) of this section, and in which the Administrator has presented to the 
manufacturer involved reasonable evidence that a violation of Sec.
86.441 in fact occurred, the manufacturer, if the wishes to contend 
that, even though the violation occurred, the vehicle in question was 
not involved in the violation to a degree that would warrant 
withholding, denial, revocation, or suspension of certification under 
either paragraph (a) (3) or (4) of this section, shall have the burden 
of establishing that contention to the satisfaction of the 
Administrator.
    (e) Any revocation or suspension of certification under paragraph 
(a) of this section shall:
    (1) Be made only after the manufacturer concerned has been offered 
an opportunity for a hearing conducted in accordance with Sec.86.444 
hereof.
    (2) Extend no further than to forbid the introduction into commerce 
of vehicles previously covered by the certification which are still in 
the hands of the manufacturer, except in cases of such fraud or other 
misconduct as makes the certification invalid ab initio.
    (f) The manufacturer may request in the form and manner specified in 
Sec.86.443 that any determination made by the Administrator under 
paragraph (a) of this section to withhold or deny certification be 
reviewed in a hearing conducted in accordance with Sec.86.444. If the 
Administrator finds, after a review of the request and supporting data, 
that the request raises a substantial factual issue, he will grant the 
request with respect to such issue.

Sec.86.445-2006  What temporary provisions address hardship due
to unusual circumstances?

    (a) After considering the circumstances, the Director of the Office 
of Transportation and Air Quality may permit you to introduce into 
commerce highway motorcycles that do not comply with emission standards 
if all the following conditions and requirements apply:
    (1) Unusual circumstances that are clearly outside your control and 
that could not have been avoided with reasonable discretion prevent you 
from meeting requirements from this chapter.
    (2) You exercised prudent planning and were not able to avoid the 
violation; you have taken all reasonable steps to minimize the extent of 
the nonconformity.
    (3) Not having the exemption will jeopardize the solvency of your 
company.
    (4) No other allowances are available under the regulations of this 
part to avoid the impending violation, excluding those in Sec.86.446.
    (b) To apply for an exemption, you must send the Designated 
Compliance Officer a written request as soon as possible before you are 
in violation. In your request, show that you meet all the conditions and 
requirements in paragraph (a) of this section.
    (c) Include in your request a plan showing how you will meet all the 
applicable requirements as quickly as possible.
    (d) You must give us other relevant information if we ask for it.
    (e) We may include reasonable additional conditions on an approval 
granted under this section, including provisions to recover or otherwise 
address the lost environmental benefit or paying fees to offset any 
economic gain resulting from the exemption. For example, in the case of 
multiple tiers of emission standards, we may require that you meet the 
less stringent standards.
    (f) Add a permanent, legible label, written in block letters in 
English, to a readily visible part of each motorcycle exempted under 
this section. This label must include at least the following items:
    (1) The label heading ``EMISSION CONTROL INFORMATION''.
    (2) Your corporate name and trademark.
    (3) Engine displacement (in liters) and model year of the engine or 
whom to contact for further information.
    (4) The statement ``THIS MOTORCYCLE IS EXEMPT UNDER 40 CFR 86.445-
2006 FROM EMISSION STANDARDS AND RELATED REQUIREMENTS.''.

Sec.86.447-2006  What provisions apply to motorcycle engines below
50 cc that are certified under the Small SI program or the 
Recreational-vehicle program?

    (a) General provisions. If you are an engine manufacturer, this 
section allows you to introduce into commerce a new highway motorcycle 
(that is, a motorcycle that is a motor vehicle) if it has an engine 
below 50 cc that is already certified to the requirements that apply to 
engines or vehicles under 40 CFR part 90 or 1051 for the appropriate 
model year. If you comply with all the provisions of this section, we 
consider the certificate issued under 40 CFR part 90 or 1051 for each 
engine or vehicle to also be a valid certificate of conformity under 
this part 86 for its model year, without a separate application for 
certification under the requirements of this part 86. See Sec.86.448-
2006 for similar provisions that apply to vehicles that are certified to 
chassis-based standards under 40 CFR part 1051.
    (b) Vehicle-manufacturer provisions. If you are not an engine 
manufacturer, you may produce highway motorcycles using nonroad engines 
below 50 cc under this section as long as you meet all the requirements 
and conditions specified in paragraph (d) of this section. If you modify 
the nonroad engine

[[Page 777]]

in any of the ways described in paragraph (d)(2) of this section for 
installation in a highway motorcycle, we will consider you a 
manufacturer of a new highway motorcycle. Such engine modifications 
prevent you from using the provisions of this section.
    (c) Liability. Engines for which you meet the requirements of this 
section, and vehicles containing these engines, are exempt from all the 
requirements and prohibitions of this part, except for those specified 
in this section. Engines and vehicles exempted under this section must 
meet all the applicable requirements from 40 CFR part 90 or 1051. This 
applies to engine manufacturers, vehicle manufacturers who use these 
engines, and all other persons as if these engines were used in 
recreational vehicles or other nonroad applications. The prohibited acts 
of 42 U.S.C. 7522 apply to these new highway motorcycles; however, we 
consider the certificate issued under 40 CFR part 90 or 1051 for each 
engine to also be a valid certificate of conformity under this part 86 
for its model year. If we make a determination that these engines do not 
conform to the regulations during their useful life, we may require you 
to recall them under 40 CFR part 86, 90, or 1068.
    (d) Specific requirements. If you are an engine or vehicle 
manufacturer and meet all the following criteria and requirements 
regarding your new engine or vehicle, the highway motorcycle is eligible 
for an exemption under this section:
    (1) Your engine must be below 50 cc and must be covered by a valid 
certificate of conformity for Class II engines issued under 40 CFR part 
90 or for recreational vehicles under 40 CFR part 1051.
    (2) You must not make any changes to the certified engine that could 
reasonably be expected to increase its exhaust emissions for any 
pollutant, or its evaporative emissions, if applicable. For example, if 
you make any of the following changes to one of these engines, you do 
not qualify for this exemption:
    (i) Change any fuel system or evaporative system parameters from the 
certified configuration.
    (ii) Change, remove, or fail to properly install any other 
component, element of design, or calibration specified in the engine 
manufacturer's application for certification. This includes 
aftertreatment devices and all related components.
    (iii) Modify or design the engine cooling system so that 
temperatures or heat rejection rates are outside the original engine 
manufacturer's specified ranges.
    (3) You must show that fewer than 50 percent of the engine family's 
total sales in the United States are used in highway motorcycles. This 
includes engines used in any application, without regard to which 
company manufactures the vehicle or equipment. In addition, if you 
manufacture highway motorcycles, you must show that fewer than 50 
percent of the engine family's total sales in the United States are 
highway motorcycles. Show that you meet the engine-sales criterion as 
follows:
    (i) If you are the original manufacturer of the engine, base this 
showing on your sales information.
    (ii) In all other cases, you must get the original manufacturer of 
the engine to confirm the engine sales volumes based on its sales 
information.
    (4) You must ensure that the engine has the label we require under 
40 CFR part 90 or 1051.
    (5) You must add a permanent supplemental label to the engine in a 
position where it will remain clearly visible after installation in the 
vehicle. In the supplemental label, do the following:
    (i) Include the heading: ``HIGHWAY MOTORCYCLE ENGINE EMISSION 
CONTROL INFORMATION''.
    (ii) Include your full corporate name and trademark. You may instead 
include the full corporate name and trademark of another company you 
choose to designate.
    (iii) State: ``THIS ENGINE WAS ADAPTED FOR HIGHWAY USE WITHOUT 
AFFECTING ITS EMISSION CONTROLS.''.
    (iv) State the date you finished installation (month and year), if 
applicable.
    (6) Send the Designated Compliance Officer a signed letter by the 
end of each calendar year (or less often if we

[[Page 778]]

tell you) with all the following information:
    (i) Identify your full corporate name, address, and telephone 
number.
    (ii) List the engine or vehicle models you expect to produce under 
this exemption in the coming year.
    (iii) State: ``We produce each listed [engine or vehicle] model for 
without making any changes that could increase its certified emission 
levels, as described in 40 CFR 86.447-2006.''.
    (e) Failure to comply. If your highway motorcycles do not meet the 
criteria listed in paragraph (d) of this section, they will be subject 
to the standards, requirements, and prohibitions of this part 86 and the 
certificate issued under 40 CFR part 90 or 1051 will not be deemed to 
also be a certificate issued under this part 86. Introducing these 
engines into commerce without a valid exemption or certificate of 
conformity under this part violates the prohibitions in 40 CFR part 85.
    (f) Data submission. We may require you to send us emission test 
data on any applicable nonroad duty cycles.
    (g) Participation in averaging, banking and trading. Engines or 
vehicles adapted for recreational use under this section may not 
generate or use emission credits under this part 86. These engines or 
vehicles may generate credits under the ABT provisions in 40 CFR part 90 
or 1051. These engines or vehicles must use emission credits under 40 
CFR part 90 or 1051 if they are certified to an FEL that exceeds an 
applicable standard.

[70 FR 40435, July 13, 2005]



Sec.86.448-2006  What provisions apply to vehicles certified under
the Recreational-vehicle program?

    (a) General provisions. If you are a highway-motorcycle 
manufacturer, this section allows you to introduce into commerce a new 
highway motorcycle with an engine below 50 cc if it is already certified 
to the requirements that apply to recreational vehicles under 40 CFR 
parts 1051. A highway motorcycle is a motorcycle that is a motor 
vehicle. If you comply with all of the provisions of this section, we 
consider the certificate issued under 40 CFR part 1051 for each 
recreational vehicle to also be a valid certificate of conformity for 
the motor vehicle under this part 86 for its model year, without a 
separate application for certification under the requirements of this 
part 86. See Sec.86.447-2006 for similar provisions that apply to 
nonroad engines produced for highway motorcycles.
    (b) Nonrecreational-vehicle provisions. If you are not a 
recreational-vehicle manufacturer, you may produce highway motorcycles 
from recreational vehicles with engines below 50 cc under this section 
as long as you meet all the requirements and conditions specified in 
paragraph (d) of this section. If you modify the recreational vehicle or 
its engine in any of the ways described in paragraph (d)(2) of this 
section for installation in a highway motorcycle, we will consider you a 
manufacturer of a new highway motorcycle. Such modifications prevent you 
from using the provisions of this section.
    (c) Liability. Vehicles for which you meet the requirements of this 
section are exempt from all the requirements and prohibitions of this 
part, except for those specified in this section. Engines and vehicles 
exempted under this section must meet all the applicable requirements 
from 40 CFR part 1051. This applies to engine manufacturers, vehicle 
manufacturers, and all other persons as if the highway motorcycles were 
recreational vehicles. The prohibited acts of 42 U.S.C. 7522 apply to 
these new highway motorcycles; however, we consider the certificate 
issued under 40 CFR part 1051 for each recreational vehicle to also be a 
valid certificate of conformity for the highway motorcycle under this 
part 86 for its model year. If we make a determination that these 
engines or vehicles do not conform to the regulations during their 
useful life, we may require you to recall them under 40 CFR part 86 or 
40 CFR 1068.505.
    (d) Specific requirements. If you are a recreational-vehicle 
manufacturer and meet all the following criteria and requirements 
regarding your new highway motorcycle and its engine, the highway 
motorcycle is eligible for an exemption under this section:
    (1) Your motorcycle must have an engine below 50 cc and it must be 
covered by a valid certificate of conformity as

[[Page 779]]

a recreational vehicle issued under 40 CFR part 1051.
    (2) You must not make any changes to the certified recreational 
vehicle that we could reasonably expect to increase its exhaust 
emissions for any pollutant, or its evaporative emissions if it is 
subject to evaporative-emission standards. For example, if you make any 
of the following changes, you do not qualify for this exemption:
    (i) Change any fuel system parameters from the certified 
configuration.
    (ii) Change, remove, or fail to properly install any other 
component, element of design, or calibration specified in the vehicle 
manufacturer's application for certification. This includes 
aftertreatment devices and all related components.
    (iii) Modify or design the engine cooling system so that 
temperatures or heat rejection rates are outside the original vehicle 
manufacturer's specified ranges.
    (3) You must show that fewer than 50 percent of the engine family's 
total sales in the United States are used in highway motorcycles. This 
includes highway and off-highway motorcycles, without regard to which 
company completes the manufacturing of the highway motorcycle. Show this 
as follows:
    (i) If you are the original manufacturer of the vehicle, base this 
showing on your sales information.
    (ii) In all other cases, you must get the original manufacturer of 
the vehicle to confirm this based on their sales information.
    (4) The highway motorcycle must have the vehicle emission control 
information we require under 40 CFR part 1051.
    (5) You must add a permanent supplemental label to the highway 
motorcycle in a position where it will remain clearly visible. In the 
supplemental label, do the following:
    (i) Include the heading: ``HIGHWAY MOTORCYCLE ENGINE EMISSION 
CONTROL INFORMATION''.
    (ii) Include your full corporate name and trademark. You may instead 
include the full corporate name and trademark of another company you 
choose to designate.
    (iii) State: ``THIS VEHICLE WAS ADAPTED FOR HIGHWAY USE WITHOUT 
AFFECTING ITS EMISSION CONTROLS.''.
    (iv) State the date you finished modifying the vehicle (month and 
year), if applicable.
    (6) Send the Designated Compliance Officer a signed letter by the 
end of each calendar year (or less often if we tell you) with all the 
following information:
    (i) Identify your full corporate name, address, and telephone 
number.
    (ii) List the highway motorcycle models you expect to produce under 
this exemption in the coming year.
    (iii) State: ``We produced each listed highway motorcycle without 
making any changes that could increase its certified emission levels, as 
described in 40 CFR 86.448-2006.''.
    (e) Failure to comply. If your highway motorcycles do not meet the 
criteria listed in paragraph (d) of this section, they will be subject 
to the standards, requirements, and prohibitions of this part 86 and 40 
CFR part 85, and the certificate issued under 40 CFR part 1051 will not 
be deemed to also be a certificate issued under this part 86. 
Introducing these motorcycles into commerce without a valid exemption or 
certificate of conformity under this part violates the prohibitions in 
40 CFR part 85.
    (f) Data submission. We may require you to send us emission test 
data on the duty cycle for Class I motorcycles.
    (g) Participation in averaging, banking and trading. Recreational 
vehicles adapted for use as highway motorcycles under this section may 
not generate or use emission credits under this part 86. These engines 
may generate credits under the ABT provisions in 40 CFR part 1051. These 
engines must use emission credits under 40 CFR part 1051 if they are 
certified to an FEL that exceeds an applicable standard.

[70 FR 40436, July 13, 2005]



Sec.86.449  Averaging provisions.

    (a) This section describes how and when averaging may be used to 
show compliance with applicable HC + NOX emission standards. 
Emission credits may not be banked for use in later model years, except 
as specified in paragraph (j) of this section.

[[Page 780]]

    (1) Compliance with the Class I and Class II HC + NOX 
standards set forth in Sec.86.410-2006 (f) may be demonstrated using 
the averaging provisions of this section. To do this you must show that 
your average emission levels are at or below the applicable standards in 
Sec.86.410-2006.
    (2) Compliance with the Class III HC + NOX standards set 
forth in Sec.86.410-2006 (a)(2) may be demonstrated using the 
averaging provisions of this section. To do this you must show that your 
average emission levels are at or below the applicable standards in 
Sec.86.410-2006.
    (3) Family emission limits (FELs) may not exceed the following caps:

----------------------------------------------------------------------------------------------------------------
                                                                                                     FEL cap (g/

----------------------------------------------------------------------------------------------------------------

    (b) Do not include any exported vehicles in the certification 
averaging program. Include only motorcycles certified under this subpart 
and intended for sale in the United States.
    (c) To use the averaging program, do the following things:
    (1) Certify each vehicle to a family emission limit.
    (2) Calculate a preliminary average emission level according to 
paragraph (d) of this section using projected production volumes for 
your application for certification.
    (3) After the end of your model year, calculate a final average 
emission level according to paragraph (d) of this section for each 
averaging set for which you manufacture or import motorcycles.
    (d) Calculate your average emission level for each averaging set for 
each model year according to the following equation and round it to the 
nearest tenth of a g/km. Use consistent units throughout the 
calculation. The averaging sets are defined in paragraph (k) of this 
section.
    (1) Calculate the average emission level as:
    [GRAPHIC] [TIFF OMITTED] TR15JA04.000
    
Where:

FELi = The FEL to which the engine family is certified.
ULi = The useful life of the engine family.
Productioni = The number of vehicles in the engine family.

    (2) Use production projections for initial certification, and actual 
production volumes to determine compliance at the end of the model year.
    (e)(1) Maintain and keep five types of properly organized and 
indexed records for each group and for each emission family:
    (i) Model year and EPA emission family.
    (ii) FEL.
    (iii) Useful life.
    (iv) Projected production volume for the model year.
    (v) Actual production volume for the model year.
    (2) Keep paper records of this information for three years from the 
due date for the end-of-year report. You may use any additional storage 
formats or media if you like.
    (3) Follow paragraphs (f) through (i) of this section to send us the 
information you must keep.

[[Page 781]]

    (4) We may ask you to keep or send other information necessary to 
implement this subpart.
    (f) Include the following information in your application for 
certification:
    (1) A statement that, to the best of your belief, you will not have 
a negative credit balance for any motorcycle when all credits are 
calculated. This means that if you believe that your average emission 
level will be above the standard (i.e., that you will have a deficit for 
the model year), you must have banked credits pursuant to paragraph (j) 
of this section to offset the deficit.
    (2) Detailed calculations of projected emission credits (zero, 
positive, or negative) based on production projections. If you project a 
credit deficit, state the source of credits needed to offset the credit 
deficit.
    (g) At the end of each model year, send an end-of-year report.
    (1) Make sure your report includes the following things:
    (i) Calculate in detail your average emission level and any emission 
credits based on actual production volumes.
    (ii) If your average emission level is above the allowable average 
standard, state the source of credits needed to offset the credit 
deficit.
    (2) Base your production volumes on the point of first retail sale. 
This point is called the final product-purchase location.
    (3) Send end-of-year reports to the Designated Compliance Officer 
within 120 days of the end of the model year. If you send reports later, 
EPA may void your certificate ab initio.
    (4) If you generate credits for banking pursuant to paragraph (j) of 
this section and you do not send your end-of-year reports within 120 
days after the end of the model year, you may not use the credits until 
we receive and review your reports. You may not use projected credits 
pending our review.
    (5) You may correct errors discovered in your end-of-year report, 
including errors in calculating credits according to the following 
table:

------------------------------------------------------------------------
          If . . .                And if . . .          Then we . . .

    (h) Include in each report a statement certifying the accuracy and 
authenticity of its contents.
    (i) We may void a certificate of conformity for any emission family 
if you do not keep the records this section requires or give us the 
information when we ask for it.
    (j) You may include Class III motorcycles that you certify with HC + 
NOX emissions below 0.8 g/km in the following optional early 
banking program:
    (1) To include a Class III motorcycle in the early banking program, 
assign it an emission rate of 0.8 g/km when calculating your average 
emission level for compliance with the Tier 1 standards.
    (2)(i) Calculate bankable credits from the following equation:

Bonus credit = Y x [(0.8 g/km - Certified emission level)] x 
[(Production volume of engine family) x (Useful life)]

    (ii) The value of Y is defined by the model year and emission level, 
as shown in the following table:

    (3) Credits banked under this paragraph (j) may be use for 
compliance with any 2010 or later model year standards as follows:
    (i) If your average emission level is above the average standard, 
calculate your credit deficit according to the following equation, 
rounding to the nearest tenth of a gram:

Deficit = (Emission Level - Average Standard) x (Total Annual 
Production) x (Useful Life)

    (ii) Credit deficits may be offset using banked credits.
    (k) Credits may not be exchanged across averaging sets except as 
explicitly allowed by this paragraph (k).
    (1) There are two averaging sets:
    (i) Class I and Class II motorcycles certified to HC + 
NOX standards.
    (ii) Class III motorcycles.
    (2) Where a manufacturer's average HC + NOX emission 
level for Class III motorcycles (as calculated under paragraph (d)(1) of 
this section) is below the applicable standard, the manufacturer may 
generate credits that may be used show compliance with HC + 
NOX standards for Class I and Class II motorcycles during the 
same model year. Use the following equations to calculate credits and 
credit deficits for each class or subclass:

Credit = (Average Standard - Emission Level) x (Total Annual Production) 
x (Useful Life)

Deficit = (Emission Level - Average Standard) x (Total Annual 
Production) x (Useful Life)

    (l) Manufacturers participating in the averaging program of this 
section may modify FELs during the model year as specified in this 
paragraph (l).
    (1) Upon notifying EPA, manufacturers may raise the FEL for an 
engine family and begin labeling motorcycles with the new FEL.
    (2) Manufacturers may ask to lower FELs based on test data of 
production vehicles showing that the motorcycles in the engine family 
have emissions below the new FEL. Manufacturers must test the 
motorcycles according to 40 CFR part 1051, subpart D. Manufacturers may 
not begin labeling motorcycles with the new FEL until they have received 
EPA approval to do so.
    (3) Manufacturers may not change the FEL of any motorcycle that has 
been placed into service or that is no longer in their possession.

Sec.86.509-90  Exhaust gas sampling system.

    (a)(1) General. The exhaust gas sampling system is designed to 
measure the true mass emissions of vehicle exhaust. In the CVS concept 
of measuring mass emissions, two conditions must be satisfied: the total 
volume of the mixture of exhaust and dilution air must be measured and a 
continuously proportioned volume of sample must be collected for 
analysis. Mass emissions are determined from the sample concentration 
and totalized flow over the test period.
    (2) Vehicle tailpipe to CVS duct. For methanol fueled vehicles, 
cooling of the exhaust gases in the duct connecting the vehicle tailpipe 
to the CVS shall be minimized. This may be accomplished by:
    (i) Using a duct of unrestricted length maintained at a temperature 
above the maximum dew point of the exhaust, but below 121 [deg]C (250 
[deg]F); heating and possibly cooling capabilities are required; or
    (ii) Using a short duct (up to 12 feet long) constructed of smooth 
wall pipe with a minimum of flexible sections, maintained at a 
temperature above the maximum dew point of the exhaust, but below 121 
[deg]C (250 [deg]F), prior to the test and during any breaks in the test 
and uninsulated during the test (insulation may remain in place and/or 
heating may occur during testing provided maximum temperature is not 
exceeded); or
    (iii) Using smooth wall duct less than five feet long with no 
required heating. A maximum of two short flexible connectors are allowed 
under this option; or
    (iv) Omitting the duct and performing the exhaust gas dilution 
function at the motorcycle tailpipe exit.
    (3) Positive displacement pump. The Positive Displacement Pump-
Constant Volume Sampler (PDP-CVS), Figure F90-1 satisfies the first 
condition by metering at a constant temperature and pressure through the 
pump. The total volume is measured by counting

[[Page 784]]

the revolutions made by the calibrated positive displacement pump. The 
proportional samples are achieved by sampling at a constant flow rate. 
For methanol-fueled motorcycle sample lines for the methanol and 
formaldehyde samples are heated to prevent condensation. The temperature 
of the sample lines shall be more than 3 [deg]C (5 [deg]F) above the 
maximum dew point of the sample, but below 121 [deg]C (250 [deg]F). 
(Note: For 1990 through 1994 model year methanol-fueled motorcycles, 
methanol and formaldehyde sampling may be omitted provided the bag 
sample (hydrocarbons and methanol) is analyzed using a HFID calibrated 
with methanol.)

[[Page 785]]

[GRAPHIC] [TIFF OMITTED] TR06OC93.173

    (4) Critical flow venturi. The operation of the Critical Flow 
Venturi--Constant Volume Sampler (CFV-CVS) sample system, Figure F90-2, 
is based upon the principles of fluid dynamics associated with critical 
flow. Proportional sampling throughout temperature excursions is 
maintained by use of small

[[Page 786]]

CFVs in the sample lines, which respond to the varying temperatures in 
the same manner as the main CFV. For methanol-fueled motorcycles, the 
methanol and formaldehyde sample lines are heated to prevent 
condensation. The temperature of the sample lines shall be more than 3 
[deg]C (5 [deg]F) above the maximum dew point of the sample, but below 
121 [deg]C (250 [deg]F). Care must be taken to ensure that the CFVs of 
the sample probes are not heated since heating of the CFVs would cause 
loss of proportionality. (Note: For 1990 through 1994 model year 
methanol-fueled motorcycles, methanol and formaldehyde sampling may be 
omitted provided the bag sample (hydrocarbons and methanol) is analyzed 
using a HFID calibrated with methanol.) Total flow per test is 
determined by continuously computing and integrating instantaneous flow. 
A low response time temperature sensor is necessary for accurate flow 
calculation.

[GRAPHIC] [TIFF OMITTED] TR06OC93.175

    (5) Electronic Flow Control. The Critical Flow Venturi--Electronic 
Flow Control--Constant Volume Sampler (CFV-EFC-CVS) system is identical 
to the CFV-CVS system described in paragraphs (a)(4) and (c) of this 
section, except that it maintains proportional sampling for methanol and 
formaldehyde by measuring the CVS flow rate, and electronically 
controlling sample flow rates. It is recommended that sample volumes be 
measured by separate flow meters. For methanol-fueled motorcycles, the 
samples lines for the methanol and formaldehyde samples are heated to 
prevent condensation. The temperature of the sample lines shall be more 
than 20 [deg]F (11 [deg]C) above

[[Page 789]]

the maximum dew point of the sample, but below 121 [deg]C (250 [deg]F).
    (6) Other systems. Other sampling systems may be used if shown to 
yield equivalent results, and if approved in advance by the 
Administrator (e.g., a heat exchanger with the CFV-CVS or an electronic 
flow integrator without a heat exchanger, with the PDP-CVS).
    (b) Component description, PDP-CVS. The PDP-CVS, Figure F90-1, 
consists of a dilution air filter and mixing assembly, heat exchanger, 
positive displacement pump, sampling systems including, probes and 
sampling lines which, in the case of the methanol-fueled motorcycles, 
are heated to prevent condensation (heating of the sample lines may be 
omitted, provided the methanol and formaldehyde sample collection 
systems are close coupled to the probes thereby preventing loss of 
sample due to cooling and resulting condensation in the sample lines), 
and associated valves, pressure and temperature sensors. The PDP-CVS 
shall conform to the following requirements:
    (1) Static pressure variations at the tailpipe(s) of the vehicle 
shall remain within 1.25 kPa (5.02 in H2O) of the static pressure 
variations measured during a dynamometer driving cycle with no 
connection to the tailpipe(s). (Sampling systems capable of maintaining 
the static pressure to within 0.25 kPa (1.00 in. H2O) will be used by the 
Administrator if a written request substantiates the need for this 
closer tolerance.)
    (2) The gas mixture temperature, measured at a point immediately 
ahead of the positive displacement pump, shall be within 5 [deg]C (9 [deg]F) of the designed operating 
temperature at the start of the test. The gas mixture temperature 
variation from its value at the start of the test shall be limited to 
5 [deg]C (9 [deg]F) during the entire test. The 
temperature measuring system shall have an accuracy and precision of 
1 [deg]C (1.8 [deg]F).
    (3) The pressure gauges shall have an accuracy and precision of 
0.4 kPa (3 mm Hg).
    (4) The location of the dilution air inlet shall be placed so as to 
use test-cell air for dilution and the flow capacity of the CVS shall be 
large enough to completely eliminate water condensation in the dilution 
and sampling systems. Control of water condensation with methanol-fueled 
vehicles is critical. Additional care may also be required to eliminate 
water condensation when testing natural gas and liquefied petroleum gas-
fueled vehicles. (Procedures for determining CVS flow rates are detailed 
in ``Calculation of Emissions and Fuel Economy When Using Alternative 
Fuels,'' EPA 460/3-83-009.) Dehumidifying the dilution air before 
entering the CVS is allowed. Heating the dilution air is also allowed, 
provided:
    (i) The air (or air plus exhaust gas) temperature does not exceed 
121 [deg]C (250 [deg]F).
    (ii) Calculation of the CVS flow rate necessary to prevent water 
condensation is based on the lowest temperature encountered in the CVS 
prior to sampling. (It is recommended that the CVS system be insulated 
when heated dilution air is used.)
    (iii) The dilution ratio is sufficiently high to prevent 
condensation in bag samples as they cool to room temperature.
    (5) Sample collection bags for dilution air and exhaust samples 
(hydrocarbons and carbon monoide) shall be of sufficient size so as not 
to impede sample flow. A single dilution air sample, covering the total 
test period, may be collected for the determination of methanol and 
formaldehyde background (methanol-fueled motorcycles).
    (6) The methanol sample collection system and the formaldehyde 
sample collection system shall each be of sufficient capacity so as to 
collect samples of adequate size for analysis without significant impact 
on the volume of dilute exhaust passing through the PDP. The systems 
shall also comply with the following requirements that apply to the 
design of the systems, not to individual tests:
    (i) The methanol system shall be designed such that if a test 
motorcycle continuously emitted the maximum allowable level of methanol 
(based on all applicable standards) the measured concentration in the 
primary impinger would exceed either 25 mg/l or a concentration equal to 
25 times the limit of detection for the GC analyzer.

[[Page 790]]

    (ii) The formaldehyde system shall be designed such that if a test 
motorcycle continuously emitted formaldehyde at a rate equal to twenty 
percent of the maximum allowable level of THCE (i.e., 1.0 g/km for a 5.0 
g/km standard), or the maximum formaldehyde level allowed by a specific 
formaldehyde standard, whichever is less, the concentration of 
formaldehyde in the DNPH solution of the primary impinger, or solution 
resulting from the extraction of the DNPH cartridge, shall exceed either 
2.5 mg/l or a concentration equal to 25 times the limit of detection for 
the HPLC analyzer.
    (iii) The methanol and formaldehyde systems shall be designed such 
that the primary impinger collects at least 90 percent of the analyte in 
the samples. The remaining analyte shall be collected by the secondary 
impinger. This requirement does not apply to dilution air samples, since 
they do not require secondary impingers, or to samples in which the 
concentrations approach the limit of detection.
    (c) Component description, CFV-CVS. The CFV-CVS sample system, 
Figure F90-2, consists of a dilution air filter and mixing assembly, a 
cyclone particulate separator, unheated sampling venturies for the bag 
samples, and for the methanol and formaldehyde samples from methanol-
fueled vehicles, samples lines heated to prevent condensation for the 
methanol and formaldehyde samples from methanol fueled vehicles (heating 
of the sample lines may be omitted provided, the methanol and 
formaldehyde sample collection systems are close coupled to the probes 
thereby preventing loss of sample due to cooling and resulting 
condensation in the sample lines), a critical flow venturi, and assorted 
valves, and pressure and temperature sensors. The CFV sample system 
shall conform to the following requirements:
    (1) Static pressure variations at the tailpipe(s) of the vehicle 
shall remain within 1.25 kPa (5.02 in 
H2O) of the static pressure variations measured during a 
dynamometer driving cycle with no connection to the tailpipe(s). 
(Sampling systems capable of maintaining the static pressure to within 
0.25 kPa (1.00 in H2O) will be used by 
the Administrator if a written request substantiates the need for this 
closer tolerance.)
    (2) The temperature measuring system shall have an accuracy and 
precision of 1 [deg]C (1.8 [deg]F) and a response 
time of 0.100 second to 62.5 percent of a temperature change (as 
measured in hot silicone oil).
    (3) The pressure measuring system shall have an accuracy and 
precision of 0.4 kPa (3 mm 
Hg).
    (4) The location of the dilution air inlet shall be placed so as to 
use test-cell air for dilution and the flow capacity of the CVS shall be 
large enough to completely eliminate water condensation in the dilution 
and sampling systems. Control of water condensation with methanol-fueled 
vehicles is critical. Additional care may also be required to eliminate 
water condensation when testing natural gas and liquefied petroleum gas-
fueled vehicles. (Procedures for determining CVS flow rates are detailed 
in ``Calculation of Emissions and Fuel Economy When Using Alternative 
Fuels,'' EPA 460/3-83-009.) Dehumidifying the dilution air before 
entering the CVS is allowed. Heating the dilution air is also allowed, 
provided:
    (i) The air (or air plus exhaust gas) temperature does not exceed 
250 [deg]F.
    (ii) Calculation of the CVS flow rate necessary to prevent water 
condensation is based on the lowest temperature encountered in the CVS 
prior to sampling. (It is recommended that the CVS system be insulated 
when heated dilution air is used.)
    (iii) The dilution ratio is sufficiently high to prevent 
condensation in bag samples as they cool to room temperature.
    (5) Sample collection bags for dilution air and exhaust samples 
(hydrocarbons and carbon monoxide) shall be of sufficient size so as not 
to impede sample flow. A single dilution air sample, covering the total 
test period, may be collected for the determination of methanol and 
formaldehyde background (methanol-fueled motorcycles).
    (6) The methanol sample collection system and the formaldehyde 
sample collection system shall each be of sufficient capacity so as to 
collect samples of adequate size for analysis without

[[Page 791]]

significant impact on the volume of dilute exhaust passing through the 
CVS. The systems shall also comply with the following requirements that 
apply to the design of the systems, not to individual tests:
    (i) The methanol system shall be designed such that if a test 
motorcycle continuously emitted the maximum allowable level of methanol 
(based on all applicable standards) the measured concentration in the 
primary impinger would exceed either 25 mg/l or a concentration equal to 
25 times the limit of detection for the GC analyzer.
    (ii) The formaldehyde system shall be designed such that if a test 
motorcycle continuously emitted formaldehyde at a rate equal to twenty 
percent of the maximum allowable level of THCE (i.e., 1.0 g/km for a 5.0 
g/km standard), or the maximum formaldehyde level allowed by a specific 
formaldehyde standard, whichever is less, the concentration of 
formaldehyde in the DNPH solution of the primary impinger, or solution 
resulting from the extraction of the DNPH cartridge, shall exceed either 
2.5 mg/l or a concentration equal to 25 times the limit of detection for 
the HPLC analyzer.
    (iii) The methanol and formaldehyde systems shall be designed such 
that the primary impinger collects at least 90 percent of the analyte in 
the samples. The remaining analyte shall be collected by the secondary 
impinger. This requirement does not apply to dilution air samples, since 
they do not require secondary impingers, or to samples in which the 
concentrations approach the limit of detection.
    (d) Component description, CFV-EFC-CVS. The CVS sample system is 
identical to the system described in paragraph (c) of this section, plus 
includes a means of electronically measuring the CVS flow rate, and 
electronic mass flow controllers for the methanol and formaldehyde 
sample lines, and separate flow meters to totalize sample flow volumes 
(optional). The EFC sample system shall conform to all of the 
requirements listed in paragraph (c) of this section, except that the 
methanol and formaldehyde samples mat both be drawn from a single static 
probe. It also must comply with the following additional requirements:
    (1) The ratio of the CVS flow rate to the sample flow rate shall not 
deviate from the ratio at the start of the test by more than 5 percent. (The volumetric sample flow rate shall be 
varied inversely with the square root of the bulk stream temperature.)
    (2) Flow totalizers for methanol and/or formaldehyde samples shall 
have an accuracy of 2 percent. Total sample 
volumes may be obtained from the flow controllers, with the advance 
approval of the administrator, provided that the controllers can be 
shown to have an accuracy of 2 percent.

Sec.86.511-90  Exhaust gas analytical system.

    (a) Schematic drawings. Figure F90-3 is a schematic drawing of the 
exhaust gas analytical system for analysis of hydrocarbons (HC) 
(hydrocarbons plus methanol in the case of methanol-fueled motorcycles), 
carbon monoxide (CO), carbon dioxide (CO2), and oxides of 
nitrogen (NOX). Since various configurations can produce 
accurate results, exact conformance with the drawing is not required. 
Additional components such as instruments, valves, solenoids, pumps and 
switches may be used to provide additional information and coordinate 
the functions of the component systems

[[Page 792]]

[GRAPHIC] [TIFF OMITTED] TR06OC93.176

    (b) Major component description. The exhaust gas analytical system 
for HC, CO and CO2, Figure F90-3, consists of a flame 
ionization detector (FID) (heated (235[deg]15 
[deg]C (113[deg]8 [deg]C)) for methanol-fueled 
vehicles) for the determination of hydrocarbons, nondispersive infrared 
analyzers (NDIR) for the determination of carbon monoxide and carbon 
dioxide and, if oxides of nitrogen are measured, a chemiluminescence 
analyzer (CL) for the determination of oxides of nitrogen. The 
analytical system for methanol consists of a gas chromatograph (GC) 
equipped with a flame ionization detector. The analysis for formaldehyde 
is performed using high pressure liquid chromatography (HPLC) of 2,4-

[[Page 793]]

dinitrophenylhydrazine (DNPH) derivatives using ultraviolet (UV) 
detection. The exhaust gas analytical system shall conform to the 
following requirements:
    (1) The CL requires that the nitrogen dioxide present in the sample 
be converted to nitric oxide before analysis. Other types of analyzers 
may be used if shown to yield equivalent results and if approved in 
advance by the Administrator.
    (2) The carbon monoxide (CO) NDIR analyzer may require a sample 
conditioning column containing CaSO4, or indicating silica 
gel to remove water vapor and containing ascarite to remove carbon 
dioxide from the CO analysis stream.
    (i) If CO instruments which are essentially free of CO2 
and water vapor interference are used, the use of the conditioning 
column may be deleted, see Sec. Sec.86.522 and 86.544.
    (ii) A CO instrument will be considered to be essentially free of 
CO2 and water vapor interference if its response to a mixture 
of 3 percent CO2 in N2 which has been bubbled 
through water at room temperature produces an equivalent CO response, as 
measured on the most sensitive CO range, which is less than 1 percent of 
full scale CO concentration on ranges above 300 ppm full scale or less 
than 3 ppm on ranges below 300 ppm full scale; see Sec.86.522.
    (c) Other analyzers and equipment. Other types of analyzers and 
equipment may be used if shown to yield equivalent results and if 
approved in advance by the Administrator.

Sec.86.515-78  EPA urban dynamometer driving schedule.

    (a) The dynamometer driving schedules are listed in appendix I. The 
driving schedules are defined by a smooth trace drawn through the 
specified speed vs. time relationships. They consist of a nonrepetitive 
series of idle, acceleration, cruise, and deceleration modes of various 
time sequences and rates. Appropriate driving schedules are as follows:
    (1) Class I--Appendix I(b).
    (2) Class II--Appendix I(a)(2).
    (3) Class III--Appendix I(a)(2).
    (b) The speed tolerance at any given time on the dynamometer driving 
schedule prescribed in appendix I or as printed on a driver's aid chart 
approved by the Administrator, when conducted to meet the requirements 
of Sec.86.537 is defined by upper and lower limits. The upper limit is 
3.2 km/h (2 mph) higher than the highest point on the trace within 1 
second of the given time. The lower limit is 3.2 km/h (2 mph) lower than 
the lowest point on the trace within 1 second of the given time. Speed 
variations greater than the tolerances (such as may occur during gear 
changes) are acceptable provided they occur for less than 2 seconds on 
any occasion. Speeds lower than those prescribed are acceptable provided 
the vehicle is operated at maximum available power during such 
occurrences. When conducted to meet the requirements of Sec.86.532 the 
speed tolerance shall be as specified above, except that the upper and 
lower limits shall be 6.4 km/h (4 mph).
    (c) Figure F78-4 shows the range of acceptable speed tolerances for 
typical points. Figure F78-4(a) is typical of portions of the speed 
curve which are increasing or decreasing throughout the two second time 
interval. Figure F78-4(b) is typical of portions of the speed curve 
which include a maximum or minimum value.
[GRAPHIC] [TIFF OMITTED] TR06OC93.177

    (d) For motorcycles with an engine displacement less than 50 cc and 
a top speed less than 58.7 km/hr (36.5 mph), the speed indicated for 
each second of operation on the applicable Class I driving trace (speed 
versus time sequence) specified in appendix I(b) shall be adjusted 
downward by the ratio of actual top speed to specified maximum test 
speed. Calculate the ratio with three significant figures by dividing 
the top speed of the motorcycle in km/hr by 58.7. For example, for a 
motorcycle with a top speed of 48.3 km/hr (30 mph), the ratio would be 
48.3/58.7 = 0.823. The top speed to be used under this section shall be 
indicated in the manufacturer's application for certification, and shall 
be the highest sustainable speed of the motorcycle with an 80 kg rider 
on a flat paved surface. If the motorcycle is equipped with a permanent 
speed governor that is unlikely to be removed in actual use, measure the 
top speed in the governed configuration; otherwise measure the

[[Page 797]]

top speed in the ungoverned configuration.

Sec.86.516-90  Calibrations, frequency and overview.

    (a) Calibrations shall be performed as specified in Sec. Sec.
86.517 through 86.526.
    (b) [Reserved]
    (c) At least monthly or after any maintenance which could alter 
calibration, the following calibrations and checks shall be performed:
    (1) Calibrate the hydrocarbon analyzer, methane analyzer, carbon 
dioxide analyzer, carbon monoxide analyzer, and oxides of nitrogen 
analyzer (certain analyzers may require more frequent calibration 
depending on particular equipment and uses).
    (2) Calibrate the dynamometer. If the dynamometer receives a weekly 
performance check (and remains within calibration), the monthly 
calibration need not be performed.
    (3) Check the oxides of nitrogen converter efficiency.
    (d) At least weekly or after any maintenance which could alter 
calibration, the following calibrations and checks shall be performed:
    (1) [Reserved]
    (2) Perform a CVS system verification, and
    (3) Run a performance check on the dynamometer. This check may be 
omitted if the dynamometer has been calibrated within the preceding 
month.
    (e) The CVS positive displacement pump or Critical Flow Venturi 
shall be calibrated following initial installation, major maintenance or 
as necessary when indicated by the CVS system verification (described in 
Sec.86.519).
    (f) Sample conditioning columns, if used in the CO analyzer train, 
should be checked at a frequency consistent with observed column life or 
when the indicator of the column packing begins to show deterioration.

Sec.86.518-78  Dynamometer calibration.

    (a) The dynamometer shall be calibrated at least once each month or 
performance verified at least once each week and then calibrated as 
required. The dynamometer is driven above the test speed range. The 
device used to drive the dynamometer is then disengaged from the 
dynamometer and the roll is allowed to coast down. The kinetic energy of 
the system is dissipated by the dynamometer. This method neglects the 
variations in roll bearing friction due to the drive axle weight of the 
vehicle.
    (b) Calibration shall consist of coasting down the dynamometer for 
each inertia load combination used. Coastdown times for the interval 
from 70 to 60 km/h shall be within the tolerances specified in Sec.
86.529. The dynamometer adjustments necessary to produce these results 
shall be noted for future reference.
    (c) The performance check consists of conducting a dynamometer 
coastdown at one or more inertia-horsepower settings and comparing the 
coastdown time to the table in Figure F98-9 of Sec.86.529-98. If the 
coastdown time is outside the tolerance, a new calibration is required.

Sec.86.519-90  Constant volume sampler calibration.

    (a) The CVS (Constant Volume Sampler) is calibrated using an 
accurate flowmeter and restrictor valve. Measurements of various 
parameters are made and related to flow through the unit. Procedures 
used by EPA for both PDP (Positive Displacement Pump) and CFV (Critical 
Flow Venturi) are outlined below. Other procedures yielding equivalent 
results may be used if approved in advance by the Administrator. After 
the calibration curve has been obtained, verification of the entire 
system can be performed by injecting a known mass of gas into the system 
and comparing the mass indicated by the system to the true mass 
injected. An indicated error does not necessarily mean that the 
calibration is wrong, since other factors can influence the accuracy of 
the system, e.g., analyzer calibration. A verification procedure is 
found in paragraph (d) of this section.
    (b) PDP calibration. (1) The following calibration procedures 
outlines the

[[Page 798]]

equipment, the test configuration, and the various parameters which must 
be measured to establish the flow rate of the constant volume sampler 
pump. All the parameters related to the pump are simultaneously measured 
with the parameters related to a flowmeter which is connected in series 
with the pump. The calculated flow rate (at pump inlet absolute pressure 
and temperature) can then be plotted versus a correlation function which 
is the value of a specific combination of pump parameters. The linear 
equation which relates the pump flow and the correlation function is 
then determined. In the event that a CVS has a multiple speed drive, a 
calibration for each range must be performed.
    (2) This calibration procedure is based on the measurement of the 
absolute values of the pump and flowmeter parameters that relate the 
flow rate at each point. Three conditions must be maintained to assure 
the accuracy and integrity of the calibration curve. First, the pump 
pressures should be measured at taps on the pump rather than at the 
external piping on the pump inlet and outlet. Pressure taps that are 
mounted at the top center and bottom center of the pump drive headplate 
are exposed to the actual pump cavity pressures, and therefore reflect 
the absolute pressure differentials. Secondly, temperature stability 
must be maintained during the calibration. The laminar flowmeter is 
sensitive to inlet temperature oscillations which cause the data points 
to be scattered. Gradual changes (1 [deg]C (1.8 [deg]F)) in temperature are acceptable as long as 
they occur over a period of several minutes. Finally, all connections 
between the flowmeter and the CVS pump must be absolutely void of any 
leakage.
    (3) During an exhaust emission test the measurement of these same 
pump parameters enables the user to calculate the flow rate from the 
calibration equation.
    (4) Connect a system as shown in Figure F78-5. Although particular 
types of equipment are shown, other configurations that yield equivalent 
results may be used if approved in advance by the Administrator. For the 
system indicated, the following data with given accuracy are required:

    (5) After the system has been connected as shown in Figure F78-6, 
set the variable restrictor in the wide open position and run the CVS 
pump for twenty minutes. Record the calibration data.
    (6) Reset the restrictor valve to a more restricted condition in an 
increment of pump inlet depression (about 1.0 kPa (4 in. 
H2O)) that will yield a minimum of six data points for the 
total calibration. Allow the system to stabilize for 3 minutes and 
repeat the data acquisition.
    (7) Data analysis:
    (i) The air flow rate, Qs, at each test point is 
calculated from the flowmeter data using the manufacturers' prescribed 
method.
    (ii) The air flow rate is then converted to pump flow, Vo 
in m\3\ per revolution at absolute pump inlet temperature and pressure.

Vo = (Qs/n) x (Tp/293) x (101.3/
Pp)


[[Page 799]]



Where:

    (A) Vo = Pump flow, m\3\/rev (ft\3\/rev) at 
Tp, Pp.
    (B) Qs = Meter air flow rate in standard cubic meters per 
minute; standard conditions are 20 [deg]C, 101.3 kPa (68 [deg]F, 29.92 
in. Hg).
    (C) n = Pump speed in revolutions per minute.
    (D)(1) Tp = Pump inlet temperature, ([deg]K) = PTI + 273.
    (2) For English units, Tp = PTI + 460.
    (E)(1) Pp = Absolute pump inlet pressure, kPa (in. Hg) = 
PB - PPI.

    (2) For English units, Pp = PB - PPI(SP.GR./
13.57).


Where:
    (F) PB = barometric pressure, kPa (in. Hg.).
    (G) PPI = Pump inlet depression, kPa (in. fluid).
    (H) SP.GR. = Specific gravity of manometer fluid relative to water.
    (iii) The correlation function at each test point is then calculated 
from the calibration data:
[GRAPHIC] [TIFF OMITTED] TR06OC93.105


Where:
    (A) Xo = correlation function.
    (B) [Delta] Pp = The pressure differential from pump 
inlet to pump outlet, kPa (in. Hg) = Pe - Pp.
    (C)(1) Pe = Absolute pump outlet pressure, kPa (in. Hg) = 
PB + PPO.
    (2) For English units, Pe = PB + PPO(SP.GR./
13.57).

Where:
    (D) PPO = Pressure head at pump outlet, kPa (in. fluid).
    (iv) A linear least squares fit is performed to generate the 
calibration equations which have the forms:
    Vo = Do - M(Xo)
    n = A - B([Delta] Pp)
    D0' M, A, and B are the slope-intercept constants, 
describing the lines.
    (8) A CVS system that has multiple speeds shall be calibrated on 
each speed used. The calibration curves generated for the ranges will be 
approximately parallel and the intercept values, D0' will 
increase as the pump flow range decreases.
    (9) If the calibration has been performed carefully, the calculated 
values from the equation will be within 0.50 
percent of the measured value of Vo. Values of M will vary 
from one pump to another, but values of Do for pumps of the 
same make, model, and range should agree within 3 
percent of each other. Particulate influx from use will cause the pump 
slip to decrease as reflected by lower values for M. Calibrations should 
be performed at pump startup and after major maintenance to assure the 
stability of the pump slip rate. Analysis of mass injection data will 
also reflect pump slip stability.
    (c) CFV calibration. (1) Calibration of the Critical Flow Venturi 
(CFV) is based upon the flow equation for a critical venturi. Gas flow 
is a function of inlet pressure and temperature:

Where:
    (i) Qs = Flow.
    (ii) Kv = Calibration coefficient.
    (iii) P = Absolute pressure.
    (iv) T = Absolute temperature.
    The calibration procedure described below establishes the value of 
the calibration coefficient at the measured values of pressure, 
temperature and air flow.
    (2) The manufacturer's recommended procedure shall be followed for 
calibrating electronic portions of the CFV.

    (4) Set up equipment as shown in Figure F78-6 and check for leaks. 
Any leaks between the flow measuring device and the critical flow 
venturi will seriously affect the accuracy of the calibration.
    (5) Set the variable flow restrictor to the open position, start the 
blower and allow the system to stabilize. Record data from all 
instruments.
    (6) Vary the flow restrictor and make at least 8 readings across the 
critical flow range of the venturi.
    (7) Data analysis. The data recorded during the calibration are to 
be used in the following calculations:
    (i) The air flow rate, Qs, at each test point is 
calculated from the flowmeter data using the manufacturer's prescribed 
method.
    (ii) Calculate values of the calibration coefficient for each test 
point:
[GRAPHIC] [TIFF OMITTED] TR06OC93.107


Where:
    (A) Qs = Flow rate in m\3\/minute, standard conditions 
are 20 [deg]C, 101.3 kPa (68 [deg]F, 29.92 in. Hg)
    (B) Tv = Temperature at venturi inlet, [deg]K([deg]R).
    (C)(1) Pv = Pressure at venturi inlet, kPa (mm Hg) = 
PB-PPI.
    (2) For English units, Pv = PB - PPI (SP.GR./
13.57).

Where:
    (D) PPI = Venturi inlet pressure depression, kPa (in. fluid).
    (E) SP.GR. = Specific gravity of manometer fluid, relative to water.
    (iii) Plot Kv as a function of venturi inlet depression. 
For sonic flow, Kv will have a relatively constant value. As 
pressure decreases (vacuum increases), the venturi becomes unchoked and 
Kv decreases (is no longer constant). See Figure F78-7.
    (iv) For a minimum of 8 points in the critical region, calculate an 
average Kv and the standard deviation.
    (v) If the standard deviation exceeds 0.3 percent of the average 
Kv, take corrective action.
    (d) CVS system verification. The following ``gravimetric'' technique 
can be used to verify that the CVS and analytical instruments can 
accurately measure a mass of gas that has been injected into the system. 
If the CVS and analytical system will be used only in the testing of 
gasoline-fueled vehicles, the system verification may be performed using 
either propane or carbon monoxide. If the CVS and analytical system will 
be used with methanol-fueled vehicles as well as gasoline-fueled 
vehicles, system verification performance check must include a methanol 
check in addition to either the propane or carbon monoxide check. 
(Verification can also be accomplished by constant flow metering using 
critical flow orifice devices.)
    (1) Obtain a small cylinder that has been charged with pure propane 
or carbon monoxide gas (CAUTION--carbon monoxide is poisonous).
    (2) Determine a reference cylinder weight to the nearest 0.01 grams.
    (3) Operate the CVS in the normal manner and release a quantity of 
pure propane or carbon monoxide into the system during the sampling 
period (approximately 5 minutes).
    (4) Following completion of step (3) above (if methanol injection is 
required), continue to operate the CVS in the normal manner and release 
a known quantity of pure methanol (in gaseous form) into the system 
during the sampling period (approximately 5 minutes). This step does not 
need to be performed with each verification, provided that it is 
performed at least twice annually.
    (5) The calculations of Sec.86.544 are performed in the normal way 
except in the case of propane. The density of propane (0.6109 kg/m\3\/
carbon atom (17.30 g/ft\3\/carbon atom)) is used in place of the density 
of exhaust hydrocarbons. In the case of carbon monoxide, the density of 
1.164 kg/m\3\ (32.97 g/ft\3\) is used.

[[Page 801]]

In the case of methanol, the density of 1.332 kg/m\3\ (37.71 g/ft\3\) is 
used.
    (6) The gravimetric mass is subtracted from the CVS measured mass 
and then divided by the gravimetric mass to determine the percent 
accuracy of the system.
    (7) The cause for any discrepancy greater than 2 percent must be found and corrected. The 
Administrator, upon request, may waive the requirement to comply with 
2 percent methanol recovery tolerance, and instead 
require compliance with a higher tolerance (not to exceed 6 percent), provided that:
    (i) The Administrator determines that compliance with the specified 
tolerance is not practically feasible; and
    (ii) The manufacturer makes information available to the 
Administrator which indicates that the calibration tests and their 
results are consistent with good laboratory practice, and that the 
results are consistent with the results of calibration testing conducted 
by the Administrator.

Sec.86.521-90  Hydrocarbon analyzer calibration.

    (a) The FID hydrocarbon analyzer shall receive the following initial 
and periodic calibration. The HFID used with methanol-fueled vehicles 
shall be operated at 235 [deg]F15 [deg]F (113 
[deg]C8 [deg]C).
    (b) Initial and periodic optimization of detector response. Prior to 
its introduction into service and at least annually thereafter, the FID 
hydrocarbon analyzer shall be adjusted for optimum hydrocarbon response. 
Analyzers used with petroleum fuels and liquefied petroleum gas-fuel 
shall be optimized using propane. Analyzers used with natural gas-fuel 
for measurement of hydrocarbons shall be optimized using methane. If a 
single analyzer is used for all measurements, it shall be optimized 
using propane and its response factor for methane shall be determined 
and accounted for in measurements of total hydrocarbons from natural 
gas-fuel. Alternate methods yielding equivalent results may be used, if 
approved in advance by the Administrator.
    (1) Follow the manufacturer's instructions or good engineering 
practice for instrument startup and basic operating adjustment using the 
appropriate FID fuel and zero-grade air.
    (2) Optimize on the most common operating range. Introduce into the 
analyzer a propane (methane as appropriate) in air mixture (methanol in 
air mixture for methanol-fueled vehicles when optional methanol 
calibrated FID procedure is used during the 1990 through 1994 model 
year) with a propane (or methane or methanol as appropriate) 
concentration equal to approximately 90 percent of the most common 
operating range.
    (3) Select an operating FID fuel flow rate that will give near 
maximum response and least variation in response with minor fuel flow 
variations.
    (4) To determine the optimum air flow, use the FID fuel flow setting 
determined above and vary air flow.
    (5) After the optimum flow rates have been determined, record them 
for future reference.
    (c) Initial and periodic calibration. Prior to its introduction into 
service and monthly thereafter the FID hydrocarbon analyzer shall be 
calibrated on all normally used instrument ranges, and, if applicable, 
the methanol response factor shall be determined (paragraph (d) of this 
section). Use the same flow rate as when analyzing sample.
    (1) Adjust analyzer to optimize performance.
    (2) Zero the hydrocarbon analyzer with zero grade air.
    (3) Calibrate on each normally used operating range with propane in 
air (or methanol or methane in air as appropriate) calibration gases 
having nominal concentrations of 15, 30, 45, 60, 75 and 90 percent of 
that range. For each range calibrated, if the deviation from a least 
squares best-fit straight line is two percent or less of the value at 
each data point, concentration values may be calculated by use of a 
single calibration factor for that range. If the deviation exceeds two 
percent at any point, the best-fit non-linear equation which represents 
the data to within two percent of each test point shall be used to 
determine concentration.
    (d) FID response factor to methanol. When the FID analyzer is to be 
used for the analysis of hydrocarbon samples

[[Page 802]]

containing methanol, the methanol response factor of the analyzer shall 
be established. The methanol response factor shall be determined at 
several concentrations in the range of concentrations in the exhaust 
sample, using either bag samples or gas bottles meeting the requirements 
of Sec.86.514.
    (1) The bag sample, if used, of methanol for analysis in the FID 
shall be prepared using the apparatus shown in Figure F90-4. A known 
volume of methanol is injected, using a microliter syringe, into the 
heated mixing zone (250 [deg]F (121 [deg]C)) of the apparatus. The 
methanol is vaporized and swept into the sample bag with a known volume 
of zero grade air measured by a gas flow meter meeting the performance 
requirements of Sec.86.120.

[[Page 803]]

[GRAPHIC] [TIFF OMITTED] TR06OC93.180

    (2) The bag sample is analyzed using the FID.
    (3) The FID response factor, r, is calculated as follows:
    r = FIDppm/SAMppm

Where:
    (i) r = FID response factor.

[[Page 804]]

    (ii) FIDppm = FID reading, ppmC.
    (iii) SAMppm = methanol concentration in the sample bag, or gas 
bottle, in ppmC. SAMppm for sample bags:
[GRAPHIC] [TIFF OMITTED] TR06OC93.108


Where:
    (iv) 0.02406 = Volume of one mole at 101.3 kPa (29.92 in. Hg) and 20 
[deg]C (68 [deg]F), m\3\.
    (v) Fuel injected = Volume of methanol injected, ml.
    (vi) Fuel Density = Density of methanol, 0.7914 g/ml
    (vii) Air volume = Volume of zero grade air, m\3\
    (viii) Mol. Wt. CH3OH = 32.04
    (e) FID response factor to methane. When the FID analyzer is to be 
used for the analysis of natural gas-fueled motorcycle hydrocarbon 
samples, the methane response factor of the analyzer shall be 
established. To determine the total hydrocarbon FID response to methane, 
known methane in air concentrations traceable to National Institute of 
Standards and Technology (NIST) shall be analyzed by the FID. Several 
methane concentrations shall be analyzed by the FID in the range of 
concentrations in the exhaust sample. The total hydrocarbon FID response 
to methane is calculated as follows:
rCH4 = FIDppm/SAMppm

Where:
(1) rCH4 = FID response factor to methane.
(2) FIDppm = FID reading in ppmC.
(3) SAMppm = the known methane concentration in ppmC.

Sec.86.522-78  Carbon monoxide analyzer calibration.

    (a) Initial and periodic interference check. Prior to its 
introduction into service and annually thereafter the NDIR carbon 
monoxide analyzer shall be checked for response to water vapor and 
CO2:
    (1) Follow the manufacturer's instructions for instrument startup 
and operation. Adjust the analyzer to optimize performance on the most 
sensitive range.
    (2) Zero the carbon monoxide analyzer with either zero grade air or 
zero grade nitrogen.
    (3) Bubble a mixture of 3 percent CO2 in N2 
through water at room temperature and record analyzer response.
    (4) An analyzer response of more than 1 percent of full scale for 
ranges above 300 ppm full scale or of more than 3 ppm on ranges below 
300 ppm full scale will require corrective action. (Use of conditioning 
columns is one form of corrective action which may be taken.)
    (b) Initial and periodic calibration. Prior to its introduction into 
service and monthly thereafter the NDIR carbon monoxide analyzer shall 
be calibrated.
    (1) Adjust the analyzer to optimize performance.
    (2) Zero the carbon monoxide analyzer with either zero grade air or 
zero grade nitrogen.
    (3) Calibrate on each normally used operating range with carbon 
monoxide in N2 calibration gases having nominal 
concentrations of 15, 30, 45, 60, 75, and 90 percent of that range. 
Additional calibration points may be generated. For each range 
calibrated, if the deviation from a least-squares best-fit straight line 
is 2 percent or less of the value at each data point, concentration 
values may be calculated by use of a single calibration factor for that 
range. If the deviation exceeds 2 percent at any point, the best-fit 
non-linear equation which represents the data to within 2 percent of 
each test point shall be used to determine concentration.



Sec.86.523-78  Oxides of nitrogen analyzer calibration.

    (a) Prior to introduction into service and at least monthly 
thereafter, if oxides of nitrogen are measured, the chemiluminescent 
oxides of nitrogen analyzer must be checked for NO2 to NO 
converter efficiency. Figure F78-8 is a reference for paragraphs (a) (1) 
through (11) of this section.

[[Page 805]]

[GRAPHIC] [TIFF OMITTED] TR06OC93.181

    (1) Follow the manufacturer's instructions for instrument startup 
and operation. Adjust the analyzer to optimize performance.
    (2) Zero the oxides of nitrogen analyzer with zero grade air or zero 
grade nitrogen.
    (3) Connect the outlet of the NOX generator to the sample 
inlet of the oxides of nitrogen analyzer which has been set to the most 
common operating range.
    (4) Introduce into the NOX generator analyzer-system a NO 
in nitrogen (N2) mixture with a NO concentration equal to 
approximately 80 percent of the most common operating range. The 
NO2 content of the gas mixture shall be less than 5 percent 
of the NO concentration.
    (5) With the oxides of nitrogen analyzer in the NO mode, record the 
concentration of NO indicated by the analyzer.
    (6) Turn on the NOX generator O2 (or air) 
supply and adjust the O2 (or air) flow rate so that the NO 
indicated by the analyzer is about 10 percent less than indicated in 
step 5. Record the concentration of NO in this NO + O2 
mixture.
    (7) Switch the NOX generator to the generation mode and 
adjust the generation rate so that the NO measured on

[[Page 806]]

the analyzer is 20 percent of that measured in step 5. There must be at 
least 10 percent unreacted NO at this point. Record the concentration of 
residual NO.
    (8) Switch the oxides of nitrogen analyzer to the NOX 
mode and measure total NOX. Record this value.
    (9) Switch off the NOX generation but maintain gas flow 
through the system. The oxides of nitrogen analyzer will indicate the 
NOX in the NO + O2 mixture. Record this value.
    (10) Turn off the NOX generator O2 (or air) 
supply. The analyzer will now indicate the NOX in the 
original NO in N2 mixture. This value should be no more than 
5 percent above the value indicated in step 4.
    (11) Calculate the efficiency of the NOX converter by 
substituting the concentrations obtained into the following equation:

Percent Efficiency = [1 + (a - b)/(c - d)] x 100

where:

a = concentration obtained in step (8).
b = concentration obtained in step (9).
c = concentration obtained in step (6).
d = concentration obtained in step (7).


If converter efficiency is not greater than 90 percent corrective action 
will be required.
    (b) Initial and periodic calibration. Prior to its introduction into 
service and monthly thereafter, if oxides of nitrogen are measured, the 
chemiluminescent oxides of nitrogen analyzer shall be calibrated on all 
normally used instrument ranges. Use the same flow rate as when 
analyzing samples. Proceed as follows:
    (1) Adjust analyzer to optimize performance.
    (2) Zero the oxides of nitrogen analyzer with zero grade air or zero 
grade nitrogen.
    (3) Calibrate on each normally used operating range with NO in 
N2 calibration gases with nominal concentrations of 50 and 
100 percent of that range. Additional calibration points may be 
generated.
    (c) When testing methanol-fueled motorcycles, it may be necessary to 
clean the analyzer frequently to prevent interference with 
NOX measurements (see EPA/600/S3-88/040).

Sec.86.524-78  Carbon dioxide analyzer calibration.

    (a) Prior to its introduction into service and monthly thereafter 
the NDIR carbon dioxide analyzer shall be calibrated:
    (1) Follow the manufacturer's instructions for instrument startup 
and operation. Adjust the analyzer to optimize performance.
    (2) Zero the carbon dioxide analyzer with either zero grade air or 
zero grade nitrogen.
    (3) Calibrate on each normally used operating range with carbon 
dioxide in N2 calibration gases with nominal concentrations 
of 15, 30, 45, 60, 75, and 90 percent of that range. Additional 
calibration points may be generated. For each range calibrated, if the 
deviation from a least-squares best-fit straight line is 2 percent or 
less of the value at each data point, concentration values may be 
calculated by use of a single calibration factor for that range. If the 
deviation exceeds 2 percent at any point, the best-fit non-linear 
equation which represents the data to within 2 percent of each test 
point shall be used to determine concentration.
    (b) [Reserved]



Sec.86.526-90  Calibration of other equipment.

    Other test equipment used for testing shall be calibrated as often 
as required by the manufacturer or as necessary according to good 
practice. Specific equipment requiring calibration is the gas 
chromatograph and flame ionization detector used in measuring methanol 
and the high pressure liquid chromatograph (HPLC) and ultraviolet 
detector for measuring formaldehyde.

[54 FR 14551, Apr. 11, 1989]



Sec.86.527-90  Test procedures, overview.

    (a) The procedures described in this and subsequent sections are 
used to determine the conformity of motorcycles with the standards set 
forth in subpart E of this part.

[[Page 807]]

    (b) The overall test consists of prescribed sequences of fueling, 
parking, and operating conditions.
    (c) The exhaust emission test is designed to determine hydrocarbon 
(gasoline-fueled, natural gas-fueled and liquefied petroleum gas-fueled 
motorcycles), methanol, formaldehyde, and hydrocarbon (methanol-fueled 
motorcycles), carbon monoxide and oxides of nitrogen mass emissions 
while simulating an average trip in an urban area. The test consists of 
engine startups and motorcycle operation on a chassis dynamometer, 
through a specified driving schedule. A proportional part of the diluted 
exhaust emissions is collected continuously for subsequent analysis, 
using a constant volume (variable dilution) sampler.
    (d) Except in cases of component malfunction or failure, all 
emission control systems installed on or incorporated in a new 
motorcycle shall be functioning during all procedures in this subpart. 
Maintenance to correct component malfunction or failure shall be 
authorized in accordance with subpart E of this part.
    (e) Background concentrations are measured for all species for which 
emissions measurements are made. For exhaust testing, this requires 
sampling and analysis of the dilution air. (When testing methanol-fueled 
motorcycles, manufacturers may choose not to measure background 
concentrations of methanol and/or formaldehyde, and then assume that the 
concentrations are zero during calculations.)

Sec.86.528-78  Transmissions.

    (a) Vehicles equipped with transfer cases, multiple sprockets, etc., 
shall be tested in the manufacturer's recommended configuration for 
street or highway use. If more than one configuration is recommended or 
if the recommendation is deemed unreasonable by the Administrator, the 
Administrator will specify the test configuration.
    (b) All tests shall be conducted with automatic transmissions in 
``Drive'' (highest gear). Automatic clutch-torque converter 
transmissions may be shifted as manual transmissions at the option of 
the manufacturer.
    (c) Idle modes shall be run with automatic transmissions in 
``Drive'' and the wheels braked, manual transmission shall be in gear 
with the clutch disengaged; except first idle, see Sec. Sec.86.536 and 
86.537.
    (d) The vehicle shall be driven with minimum throttle movement to 
maintain the desired speed. No simultaneous use of brake and throttle 
shall be permitted.
    (e) Acceleration modes shall be driven smoothly. Automatic 
transmissions shall shift automatically through the normal sequence of 
gears; manual transmissions shall be shifted as recommended by the 
manufacturer to the ultimate purchaser (unless determined to be 
unreasonable by the Administrator) with the operator closing the 
throttle during each shift and accomplishing the shift with minimum 
time. If the vehicle cannot accelerate at the specified rate, the 
vehicle shall be operated with the throttle fully opened until the 
vehicle speed reaches the value prescribed for that time in the driving 
schedule.
    (f) The deceleration modes shall be run in gear using brakes or 
throttle as necessary to maintain the desired speed. Manual transmission 
vehicles shall be downshifted using the same shift points as when 
upshifting or as recommended by the manufacturer in the vehicle owner's 
manual. All downshifts shall be made smoothly, disengaging the clutch 
while shifting and engaging the clutch once the lower gear has been 
selected. For those modes which require the vehicle to decelerate to 
zero, manual transmission clutches shall be disengaged when the speed 
drops below 15 km/h (9.3 mph) for vehicles with engine displacements 
equal to or greater than 280 cc (17.1 cu. in.), when the speed drops 
below 10 km/h (6.2 mph) for vehicles with engine displacements less than 
280 cc (17.1 cu. in.), when engine roughness is evident, or when engine 
stalling is imminent.
    (g) If downshifting during deceleration is not permitted in the 
vehicle owner's manual, manual transmissions will be downshifted at the 
beginning of or during a power mode if recommended by the manufacturer 
or if

[[Page 808]]

the engine obviously is lugging. For those modes which require these 
vehicles to decelerate to zero, manual transmission clutches shall be 
disengaged when the speed drops below 25 km/h (15.5 mph) for vehicles 
with engine displacement equal to or greater than 280 cc (17.1 cu. in.), 
when the speed drops below 20 km/h (12.4 mph) for vehicles with engine 
displacements less than 280 cc (17.1 cu. in.), when engine roughness is 
evident, or when engine stalling is imminent. While the clutch is 
disengaged and during these deceleration modes, the vehicle shall be 
shifted to the appropriate gear for starting the next mode.
    (h) If shift speeds are not recommended by the manufacturer, manual 
transmission vehicles shall be shifted as follows:
    (1) For Class I and II motorcycles:

------------------------------------------------------------------------
                Shift                                Speed

4th to 5th gear......................  53 km/h (32.9 mi/h).
------------------------------------------------------------------------

    (2) For Class III motorcycles:

------------------------------------------------------------------------
                Shift                                Speed
------------------------------------------------------------------------
1st to 2d gear.......................  30 km/h (18.6 mi/h).
2d to 3d gear........................  45 km/h (28.0 mi/h).
3d to 4th gear.......................  60 km/h (37.3 mi/h).
4th to 5th gear......................  75 km/h (46.6 mi/h).
------------------------------------------------------------------------

    (3) Higher gears may be used at the manufacturer's option.

    (a)(1) Road load as a function of speed is given by the following 
equation:

given in Figure F98-9 of this section. Velocity V is in km/h and force 
(F) is in newtons. The forces given by the equation in paragraph (a)(1) 
of this section shall be simulated to the best ability of the equipment 
being used.

    (c) The dynamometer shall be adjusted to reproduce the specified 
road load as determined by the most recent calibration. Alternatively, 
the actual vehicle road load can be measured and duplicated:
    (1) Make at least 5 replicate coastdowns in each direction from 70 
to 60 km/h on a smooth, level track under balanced wind conditions. The 
driver must have a mass of 80 10 kg and be in the 
normal driving position. Record the coastdown time.
    (2) Average the coastdown times. Adjust the dynamometer load so that 
the coastdown time is duplicated with the vehicle and driver on the 
dynamometer.

Sec.86.532-78  Vehicle preconditioning.

    (a) The vehicle shall be moved to the test area and the following 
operations performed:
    (1) The fuel tank(s) shall be drained through the provided fuel 
tank(s) drain(s) and charged with the specified test fuel, Sec.86.513, 
to half the tank(s) capacity.
    (2) The vehicle shall be placed, either by being driven or pushed,

Sec.86.535-90  Dynamometer procedure.

    (a) The dynamometer run consists of two tests, a ``cold'' start test 
and a ``hot'' start test following the ``cold'' start by 10 minutes. 
Engine startup (with all accessories turned off), operation over the 
driving schedule, and engine shutdown make a complete cold start test. 
Engine startup and operation over the first 505 seconds of the driving 
schedule complete the hot start test. The exhaust emissions are diluted 
with ambient air and a continuously proportional sample is collected for 
analysis during each phase. The composite samples collected in bags are 
analyzed for hydrocarbons, carbon monoxide, carbon dioxide, and, 
optionally, for oxides of nitrogen. A parallel sample of the dilution 
air is similarly analyzed for hydrocarbon, carbon monoxide, carbon 
dioxide, and, optionally, for oxides of nitrogen. Methanol and 
formaldehyde samples (exhaust and dilution air) are collected and 
analyzed for methanol-fueled vehicles (a single dilution air 
formaldehyde sample covering the total time of the test may be collected 
in place of individual test phases).
    (b) [Reserved]
    (c) The vehicle speed, as measured from the dynamometer roll, shall 
be used. A speed vs. time recording, as evidence of dynamometer test 
validity, shall be supplied on request of the Administrator.
    (d) Practice runs over the prescribed driving schedule may be 
performed at test points, provided an emission sample is not taken, for 
the purpose of finding the minimum throttle action to maintain the 
proper speed-time relationship, or to permit sampling system 
adjustments.
    (e) The drive wheel tires must be inflated to the manufacturer's 
recommended pressure, 15 kPa (2.2 psi). The drive wheel tire pressure shall be 
reported with the test results.

[[Page 811]]

    (f) If the dynamometer has not been operated during the two-hour 
period immediately preceding the test, it shall be warmed up for 15 
minutes by operating at 50 km/h (31 mph) using a nontest vehicle, or as 
recommended by the dynamometer manufacturer.
    (g) If the dynamometer horsepower must be adjusted manually, it 
shall be set within one hour prior to the exhaust emissions test phase. 
The test vehicle shall not be used to make this adjustment. Dynamometers 
using automatic control of preselectable power settings may be set 
anytime prior to the beginning of the emissions test.
    (h) The driving distance, as measured by counting the number of 
dynamometer roll revolutions, shall be determined for the transient cold 
start, stabilized cold start, and transient hot start phases of the 
test.

[54 FR 14551, Apr. 11, 1989]



Sec.86.536-78  Engine starting and restarting.

    (a)(1) The engine shall be started according to the manufacturer's 
recommended starting procedures. The initial 20 second idle period shall 
begin when the engine starts.
    (2) Choke operation. (i) Vehicles equipped with automatic chokes 
shall be operated according to the instructions in the manufacturer's 
operating instructions or owner's manual including choke setting and 
``kick-down'' from cold fast idle. The transmission shall be placed in 
gear 15 seconds after the engine is started. If necessary, braking may 
be employed to keep the drive wheels from turning.
    (ii) Vehicles equipped with manual chokes shall be operated 
according to the manufacturer's operating instructions or owner's 
manual. Where times are provided in the instructions, the Administrator 
may specify the specific point for operation, within 15 seconds of the 
recommended time.
    (3) The operator may use the choke, throttle etc. where necessary to 
keep the engine running.
    (4) If the manufacturer's operating instructions or owner's manual 
do not specify a warm engine starting procedure, the engine (automatic 
and manual choke engines) shall be started by opening the throttle about 
half way and cranking the engine until it starts.
    (b) [Reserved]
    (c) If, during the cold start, the vehicle does not start after 10 
seconds of cranking, or ten cycles of the manual starting mechanism, 
cranking shall cease and the reason for failure to start determined. The 
revolution counter on the constant volume sampler shall be turned off 
and the sample solenoid valves placed in the ``standby'' position during 
this diagnostic period. In addition, either the CVS blower shall be 
turned off or the exhaust tube disconnected from the tailpipe during the 
diagnostic period.
    (1) If failure to start is an operational error, the vehicle shall 
be rescheduled for testing from a cold start. If failure to start is 
caused by vehicle malfunction, corrective action (following the 
unscheduled maintenance provisions) of less than 30 minutes duration may 
be taken and the test continued. The sampling system shall be 
reactivated at the same time cranking is started. When the engine 
starts, the driving schedule timing sequence shall begin. If failure to 
start is caused by vehicle malfunction and the vehicle cannot be 
started, the test shall be voided, the vehicle removed from the 
dynamometer, corrective action taken (following the unscheduled 
maintenance provisions), and the vehicle rescheduled for test. The 
reason for the malfunction (if determined) and the corrective action 
taken shall be reported.
    (2) If the vehicle does not start during the hot start after ten 
seconds of cranking, or ten cycles of the manual starting mechanism, 
cranking shall cease, the test shall be voided, the vehicle removed from 
the dynamometer, corrective action taken in accordance with Sec.86.428 
or Sec.86.429, and the vehicle rescheduled for test. The reason for 
the malfunction (if determined) and the corrective action taken shall be 
reported.
    (d) If the engine ``false starts'', the operator shall repeat the 
recommended starting procedure (such as resetting the choke, etc.)
    (e) Stalling. (1) If the engine stalls during an idle period, the 
engine shall be restarted immediately and the test continued. If the 
engine cannot be

[[Page 812]]

started soon enough to allow the vehicle to follow the next acceleration 
as prescribed, the driving schedule indicator shall be stopped. When the 
vehicle restarts, the driving schedule indicator shall be reactivated.
    (2) If the engine stalls during some operating mode other than idle, 
the driving schedule indicator shall be stopped, the vehicle shall then 
be restarted and accelerated to the speed required at that point in the 
driving schedule and the test continued. During acceleration to this 
point, shifting shall be performed in accordance with Sec.86.528.
    (3) If the vehicle will not restart within one minute, the test 
shall be voided, the vehicle removed from the dynamometer, corrective 
action taken, and the vehicle rescheduled for test. The reason for the 
malfunction (if determined) and the corrective action taken shall be 
reported.



Sec.86.537-90  Dynamometer test runs.

    (a) The vehicle shall be allowed to stand with the engine turned off 
(see Sec.86.532 for required time). The vehicle shall be stored prior 
to the emission test in such a manner that precipitation (e.g., rain or 
dew) does not occur on the vehicle. The complete dynamometer test 
consists of a cold start drive of 12.0 km (7.5 mi), (10.9 km (6.8 mi) 
for Class I motorcycles) and simulates a hot start drive of 12.0 km (7.5 
mi), (10.9 km (6.8 mi) for Class I motorcycles). The vehicle is allowed 
to stand on the dynamometer during the 10-minute period between the cold 
and hot start tests. The cold start is divided into two periods. The 
first period, representing the cold start ``transient'' phase, 
terminates at the end of the deceleration which is scheduled to occur at 
505 seconds of the driving schedule. The second period, representing the 
``stabilized'' phase, consists of the remainder of the driving schedule 
including engine shutdown. The hot start test similarly consists of two 
periods. The period, representing the hot start ``transient'' phase, 
terminates at the same point in the driving schedule at the first point 
of the cold start test. The second period of the hot start test, 
``stabilized'' phase, is assumed to be identical to the second period of 
the cold start test. Therefore, the hot start test terminates after the 
first period (505 seconds) is run.
    (b) The following steps shall be taken for each test:
    (1) Place drive wheel of vehicle on dynamometer without starting 
engine.
    (2) Activate vehicle cooling fan.
    (3) For all vehicles, with the sample selector valves in the 
``standby'' position connect evacuated sample collection bags to the 
dilute exhaust and dilution air sample collection systems.
    (4) For methanol-fueled vehicles, with the sample selector valves in 
the ``standby'' position, insert fresh sample collection impingers into 
the methanol sample collection system, fresh impingers or a fresh 
cartridge into the formaldehyde sample collection system and fresh 
impingers (or a single cartridge for formaldehyde) into the dilution air 
sample collection systems for methanol and formaldehyde (background 
measurements of methanol and formaldehyde may be omitted and 
concentrations assumed to be zero for calculations in Sec.86.544).
    (5) Start the CVS (if not already on), the sample pumps and the 
temperature recorder. (The heat exchanger of the constant volume 
sampler, if used, methanol-fueled vehicle hydrocarbon analyzer and 
sample lines should be preheated to their respective operating 
temperatures before the test begins.)
    (6) Adjust the sample flow rates to the desired flow rate and set 
the gas flow measuring devices to zero.
    (i) For gaseous bag samples (except hydrocarbon samples), the 
minimum flow rate is 0.17 cfm (0.08 l/s).
    (ii) For hydrocarbon samples, the minimum FID (or HFID in the case 
of methanol-fueled vehicles) flow rate is 0.066 cfm (0.031 l/s).
    (iii) For methanol samples, the flow rates shall be set such that 
the system meets the design criteria of Sec.86.509. For samples in 
which the concentration in the primary impinger exceeds 0.5 mg/l, it is 
recommended that the mass of methanol collected in the secondary 
impinger not exceed ten percent of the total mass collected. For samples 
in which the concentration in the primary impinger does not exceed 0.5 
mg/l, secondary impingers do not need to be analyzed.

[[Page 813]]

    (iv) For formaldehyde samples, the flow rates shall be set such that 
the system meets the design criteria of Sec.86.509. For impinger 
samples in which the concentration of formaldehyde in the primary 
impinger exceeds 0.1 mg/l, it is recommended that the mass of 
formaldehyde collected in the secondary impinger not exceed ten percent 
of the total mass collected. For samples in which the concentration in 
the primary impinger does not exceed 0.1 mg/l, secondary impingers do 
not need to be analyzed.
    (7) Attach the flexible exhaust tube to the vehicle tailpipe(s).
    (8) Start the gas flow measuring device, position the sample 
selector valves to direct the sample flow into the ``transient'' exhaust 
sample bag, the ``transient'' methanol exhaust sample, the ``transient'' 
formaldehyde exhaust sample, the ``transient'' dilution air sample bag, 
the ``transient'' methanol dilution air sample and the ``transient'' 
formaldehyde dilution air sample, turn the key on, and start cranking 
the engine.
    (9) Fifteen seconds after the engine starts, place the transmission 
in gear.
    (10) Twenty seconds after the engine starts, begin the initial 
vehicle acceleration of the driving schedule.
    (11) Operate the vehicle according to the Urban Dynamometer Driving 
Schedule (Sec.86.515).
    (12) At the end of the deceleration which is scheduled to occur at 
505 seconds, simultaneously switch the sample flows from the 
``transient'' bags and samples to ``stabilized'' bags and samples, 
switch off gas flow measuring device No. 1 and, start gas flow measuring 
device No. 2. Before the acceleration which is scheduled to occur at 510 
seconds, record the measured roll or shaft revolutions and reset the 
counter or switch to a second counter. As soon as possible, transfer the 
``stabilized'' exhaust and dilution air samples to the analytical system 
and process the samples according to Sec.86.540, obtaining a 
stabilized reading of the exhaust bag sample on all analyzers within 20 
minutes of the end of the sample collection phase of the test. Obtain 
methanol and formaldehyde sample analyses, if applicable, within 24 
hours of the end of the sample period. (If it is not possible to perform 
analysis on the methanol and formaldehyde samples within 24 hours, the 
samples should be stored in a dark cold (4-10 [deg]C) environment until 
analysis. The samples should be analyzed within fourteen days.)
    (13) Turn the engine off 2 seconds after the end of the last 
deceleration (at 1,369 seconds).
    (14) Five seconds after the engine stops running, simultaneously 
turn off gas flow measuring device No. 2 and position the sample 
selector valves to the ``standby'' position (and open the valves 
isolating particulate filter No. 1, if applicable). Record the measured 
roll or shaft revolutions (both gas meter or flow measurement 
instrumentation readings) and re-set the counter. As soon as possible, 
transfer the ``stabilized'' exhaust and dilution air samples to the 
analytical system and process the samples according to Sec.86.540, 
obtaining a stabilized reading of the exhaust bag sample on all 
analyzers within 20 minutes of the end of the sample collection phase of 
the test. Obtain methanol and formaldehyde sample analyses, if 
applicable, within 24 hours of the end of the sample period. (If it is 
not possible to perform analysis on the methanol and formaldehyde 
samples within 24 hours, the samples should be stored in a dark cold (4-
10 [deg]C) environment until analysis. The samples should be analyzed 
within fourteen days.)
    (15) Immediately after the end of the sample period, turn off the 
cooling fan.
    (16) Turn off the CVS or disconnect the exhaust tube from the 
tailpipe(s) of the vehicle.
    (17) Repeat the steps in paragraph (b) (2) through (11) of this 
section for the hot start test, except only two evacuated sample bags, 
two methanol sample impingers, and two formaldehyde sample impingers are 
required. The step in paragraph (b)(8) of this section shall begin 
between 9 and 11 minutes after the end of the sample period for the cold 
start test.
    (18) At the end of the deceleration which is scheduled to occur at 
505 seconds, simultaneously turn off gas flow measuring device No. 1 and 
position the sample selector valve to the ``standby'' position. (Engine 
shutdown is not part of the hot start test sample

[[Page 814]]

period.) Record the measured roll or shaft revolutions.
    (19) As soon as possible, transfer the hot start ``transient'' 
exhaust and dilution air bag samples to the analytical system and 
process the samples according to Sec.86.540 obtaining a stabilized 
reading of the bag exhaust sample on all analyzers within 20 minutes of 
the end of the sample collection phase of the test. Obtain methanol and 
formaldehyde sample analyses, if applicable, within 24 hours of the end 
of the sample period (if it is not possible to perform analysis on the 
methanol and formaldehyde samples within 24 hours, the samples should be 
stored in a dark, cold ( 0 [deg]C) environment until analysis).
    (20) Disconnect the exhaust tube from the vehicle tailpipe(s) and 
remove the vehicle from dynamometer.
    (21) The CVS or CFV may be turned off, if desired.
    (22) Continuous monitoring of exhaust emissions will not normally be 
allowed. Specific written approval must be obtained from the 
Administrator for continuous monitoring of exhaust emissions.

Sec.86.540-90  Exhaust sample analysis.

    The following sequence of operations shall be performed in 
conjunction with each series of measurements:
    (a) For CO, CO2, gasoline-fueled, natural gas-fueled, 
liquefied petroleum gas-fueled and methanol-fueled motorcycle HC and, if 
appropriate, NOX:
    (1) Zero the analyzers and obtain a stable zero reading. Recheck 
after tests.
    (2) Introduce span gases and set instrument gains. In order to avoid 
errors, span and calibrate at the same flow rates used to analyze the 
test sample. Span gases should have concentrations equal to 75 to 100 
percent of full scale. If gain has shifted significantly on the 
analyzers, check the calibrations. Show actual concentrations on chart.
    (3) Check zeros; repeat the procedure in paragraphs (a) (1) and (2) 
of this section if required.
    (4) Check flow rates and pressures.
    (5) Measure HC, CO, CO2, and, if appropriate, 
NOX. concentrations of samples.
    (6) Check zero and span points. If difference is greater than 2 
percent of full scale, repeat the procedure in paragraphs (a) (1) 
through (5) of this section.
    (b) For CH3OH (methanol-fueled vehicles), introduce test 
samples into the gas chromatograph and measure the concentration. This 
concentration is CMS in the calculations.
    (c) For HCHO (methanol-fueled vehicles), introduce test samples into 
the high pressure liquid chromatograph and measure the concentration of 
formaldehyde as a dinitropheylhydrazine derivative in acetonitrile. This 
concentration is CFS in the calculations.

Sec.86.544-90  Calculations; exhaust emissions.

    This section describes how to calculate exhaust emissions. Determine 
emission results for each pollutant to at least one more decimal place 
than the applicable standard. Apply the deterioration factor, then round 
the adjusted figure to the same number of decimal places as the emission 
standard. Compare the rounded emission levels to the emission standard 
for each emission data vehicle. In the case of NOX + HC 
standards, apply the deterioration factor to each pollutant and then add 
the results before rounding.
    (a) Calculate a composite FTP emission result using the following 
equation:
[GRAPHIC] [TIFF OMITTED] TR25OC16.039


[[Page 816]]


Where:

Ywm = Weighted mass emissions of each pollutant (i.e., 
          CO2, HC, CO, or NOX) in grams per 
          vehicle kilometer and if appropriate, the weighted carbon mass 
          equivalent of total hydrocarbon equivalent, in grams per 
          vehicle kilometer.
Yct = Mass emissions as calculated from the transient phase 
          of the cold-start test, in grams per test phase.
Ys = Mass emissions as calculated from the stabilized phase 
          of the cold-start test, in grams per test phase.
Dct = The measured driving distance from the transient phase 
          of the cold-start test, in kilometers.
Ds = The measured driving distance from the stabilized phase 
          of the cold-start test, in kilometers.
Yht = Mass emissions as calculated from the transient phase 
          of the hot-start test, in grams per test phase.
Dht = The measured driving distance from the transient phase 
          of the hot-start test, in kilometers.

    (b) The mass of each pollutant for each phase of both the cold-start 
test and the hot-start test is determined from the following:
    (1) Hydrocarbon mass:

HCmass = Vmix x DensityHC x 
(HCconc/1,000,000)

    (2) Oxides of nitrogen mass:

NOxmass = Vmix x DensityNO2 x 
KH x (NOxconc/1,000,000)

    (3) Carbon monoxide mass:

delivery inspection procedures for the configuration being tested.
    (ii) Only one mechanic at a time per vehicle shall make authorized 
checks, adjustments, or repairs, unless a particular check, adjustment, 
or repair requires a second mechanic as indicated in the shop manual or 
dealer service bulletins.
    (iii) A mechanic shall not perform any check, adjustment, or repair 
without an Enforcement Officer present unless otherwise authorized.
    (iv) The manufacturer shall utilize only those tools and test 
equipment utilized by its dealers when performing authorized checks, 
adjustments, or repairs.
    (d) A manufacturer may indicate preferred assembly plants for the 
various engine families produced by the manufacturer for selection of 
vehicles in response to a test order. This shall be accomplished by 
submitting a list of engine families and the corresponding assembly 
plants from which the manufacturer desires to have vehicles selected to 
the Administrator. In order that a manufacturer's preferred location for 
issuance of a test order for a configuration of a particular engine 
family be considered, the list must be submitted prior to issuance of 
the test order. Notwithstanding the fact that a manufacturer has 
submitted the above list, the Administrator may, upon making the 
determination that evidence exists indicating noncompliance at other 
than the manufacturer's preferred plant, order testing at such other 
plant where vehicles of the configuration specified in the test order 
are assembled.
    (e) During a given model year, the Administrator shall not issue to 
a manufacturer more SEA test orders than an annual limit determined by 
dividing the projected sales bound for the U.S. market for that model 
year, as made by the manufacturer in its report submitted under 
paragraph (a)(2) of

[[Page 823]]

Sec.600.207-80 of the Automobile Fuel Economy Regulations, by 300,000 
and rounding to the nearest whole number, unless the projected sales are 
less than 150,000, in which case the annual limit is one. However, the 
annual limit for SEA test orders will be recalculated if a manufacturer 
submits to EPA in writing prior to or during the model year a sales 
projection update.
    (1) Any SEA test order for which the configuration fails in 
accordance with Sec.86.610 or for which testing is not completed does 
not count against the annual limit.
    (2) When the annual limit has been met, the Administrator may issue 
additional test orders for those configurations for which evidence 
exists indicating noncompliance. An SEA test order issued on this basis 
will include a statement as to the reason for its issuance.

Sec.86.607-84  Sample selection.

    (a) Vehicles comprising a test sample which are required to be 
tested, pursuant to a test order issued in accordance with this subpart, 
will be selected at the location and in the manner specified in the test 
order. If a manufacturer determines that the test vehicles cannot be 
selected in the manner specified in the test order, an alternative 
selection procedure may be employed: Provided, That the manufacturer 
requests approval of the alternative procedure in advance of the start 
of test sample selection and that the Administrator approves the 
procedure. Special order vehicles are exempt from sample selection 
unless a test sample cannot be completed otherwise.
    (b) The manufacturer shall have assembled the test vehicles of the 
configuration selected for testing using its normal mass production 
processes for vehicles to be distributed into commerce. During the 
audit, the manufacturer shall inform the Administrator of any change(s) 
implemented in its production processes, including quality control, 
which may be reasonably expected to affect the emissions of the vehicles 
selected, between the time the manufacturer received the test order and 
the time the manufacturer finished selecting test vehicles.
    (c) No quality control, testing, or assembly procedures will be used 
on the completed test vehicles or any portion thereof, including parts 
and subassemblies, that has not been or will not be used during the 
production and assembly of all other vehicles of that configuration.
    (d) The test order may specify that EPA Enforcement Officers, rather 
than the manufacturer, will select the test vehicles according to the 
method described in paragraph (a) of this section.

Sec.86.608-98  Test procedures.

    (a) The prescribed test procedures are the Federal Test Procedure, 
as described in subpart B of this part, and the cold temperature CO test 
procedure as described in subpart C of this part. For purposes of 
Selective Enforcement Audit testing, the manufacturer shall not be 
required to perform any of the test procedures in subpart B of this part 
relating to evaporative emission testing, other than refueling emissions 
testing, except as specified in paragraph (a)(2) of this section.
    (1) The Administrator may omit any of the testing procedures 
described in paragraph (a) of this section. Further, the Administrator 
may, on the basis of a written application by a manufacturer, approve 
optional test procedures other than those in subparts B and C of this 
part for any motor vehicle which is not susceptible to satisfactory 
testing using the procedures in subparts B and C of this part.
    (2) The following exceptions to the test procedures in subpart B of 
this part are applicable to Selective Enforcement Audit testing:
    (i) For mileage accumulation, the manufacturer may use test fuel 
meeting the specifications for mileage and service accumulation fuels of 
Sec.86.113. Otherwise, the manufacturer may use

[[Page 828]]

fuels other than those specified in this section only with the advance 
approval of the Administrator.
    (ii) The manufacturer may measure the temperature of the test fuel 
at other than the approximate mid-volume of the fuel tank, as specified 
in Sec.86.131-96(a) with only a single temperature sensor, and may 
drain the test fuel from other than the lowest point of the tank, as 
specified in Sec. Sec.86.131-96(b) and 86.152-98(a), provided an 
equivalent method is used. Equivalency documentation shall be maintained 
by the manufacturers and shall be made available to the Administrator 
upon request. Additionally, for any test vehicle that has remained under 
laboratory ambient temperature conditions for at least 6 hours prior to 
testing, the vehicle soak described in Sec.86.132-96(c) may be 
eliminated upon approval of the Administrator. In such cases, the 
vehicle shall be operated through the preconditioning drive described in 
Sec.86.132-96(c) immediately following the fuel drain and fill 
procedure described in Sec.86.132-96(b).
    (iii) The manufacturer may perform additional preconditioning on 
Selective Enforcement Audit test vehicles other than the preconditioning 
specified in Sec.86.132 only if the additional preconditioning was 
performed on certification test vehicles of the same configuration.
    (iv) [Reserved]
    (v) The manufacturer may substitute slave tires for the drive wheel 
tires on the vehicle as specified in Sec.86.135-90(e): Provided, that 
the slave tires are the same size.
    (vi) [Reserved]
    (vii) In performing exhaust sample analysis under Sec.86.140-94.
    (A) When testing diesel vehicles, or methanol-fueled Otto-cycle 
vehicles, the manufacturer shall allow a minimum of 20 minutes warm-up 
for the HC analyzer, and for diesel vehicles, a minimum of two hours 
warm-up for the CO, CO2 and NOX analyzers. (Power is normally 
left on infrared and chemiluminescent analyzers. When not in use, the 
chopper motors of the infrared analyzers are turned off and the 
phototube high voltage supply to the chemiluminescent analyzers is 
placed in the standby position.)
    (B) The manufacturer shall exercise care to prevent moisture from 
condensing in the sample collection bags.
    (viii) The manufacturer need not comply with Sec.86.142 or Sec.
86.155, since the records required therein are provided under other 
provisions of this subpart G.
    (ix) If a manufacturer elects to perform the background 
determination procedure described in paragraph (a)(2)(xi) of this 
section in addition to performing the refueling emissions test 
procedure, the elapsed time between the initial and final FID readings 
shall be recorded, rounded to the nearest second rather than minute as 
described in Sec.86.154-98(e)(8). In addition, the vehicle soak 
described in Sec.86.153-98(e) shall be conducted with the windows and 
luggage compartment of the vehicle open.
    (x) The Administrator may elect to perform a seal test, described in 
Sec.86.153-98(b), of both integrated and non-integrated systems 
instead of the full refueling test. When testing non-integrated systems, 
a manufacturer may conduct the canister purge described in Sec.86.153-
98(b)(1) directly following the preconditioning drive described in Sec.
86.132-96(e) or directly following the exhaust emissions test described 
in Sec.86.137-96.
    (xi) In addition to the refueling test, a manufacturer may elect to 
perform the following background emissions determination immediately 
prior to the refueling measurement procedure described in Sec.86.154, 
provided EPA is notified of this decision prior to the start of testing 
in an SEA.
    (A) The SHED shall be purged for several minutes immediately prior 
to the background determination. Warning: If at any time the 
concentration of hydrocarbons, of methanol, or of methanol and 
hydrocarbons exceeds 15,000 ppm C, the enclosure should be immediately 
purged. This concentration provides a 4:1 safety factor against the lean 
flammability limit.
    (B) The FID (or HFID) hydrocarbon analyzer shall be zeroed and 
spanned immediately prior to the background determination. If not 
already on, the enclosure mixing fan and the spilled fuel mixing blower 
shall be turned on at this time.

[[Page 829]]

    (C) Place the vehicle in the SHED. The ambient temperature level 
encountered by the test vehicle during the entire background emissions 
determination shall be 80 [deg]F 3 [deg]F. The 
windows and luggage compartment of the vehicle must be open and the gas 
cap must be secured.
    (D) Seal the SHED. Immediately analyze the ambient concentration of 
hydrocarbons in the SHED and record. This is the initial background 
hydrocarbon concentration.
    (E) Soak the vehicle for ten minutes 1 minute.
    (F) The FID (or HFID) hydrocarbon analyzer shall be zeroed and 
spanned immediately prior to the end of the background determination.
    (G) Analyze the ambient concentration of hydrocarbons in the SHED 
and record. This is the final background hydrocarbon concentration.
    (H) The total hydrocarbon mass emitted during the background 
determination is calculated according to Sec.86.156. To obtain a per-
minute background emission rate, divide the total hydrocarbon mass 
calculated in this paragraph by the duration of the soak, rounded to the 
nearest second, described in paragraph (a)(2)(xi)(G) of this section.
    (I) The background emission rate is multiplied by the duration of 
the refueling measurement obtained in paragraph (a)(2)(ix) of this 
section. This number is then subtracted from the total grams of 
emissions calculated for the refueling test according to Sec.86.156-
98(a) to obtain the adjusted value for total refueling emissions. The 
final results for comparison with the refueling emission standard shall 
be computed by dividing the adjusted value for total refueling mass 
emissions by the total gallons of fuel dispensed in the refueling test 
as described in Sec.86.156-98(b).
    (xii) In addition to the requirements of subpart B of this part, the 
manufacturer shall prepare gasoline-fueled and methanol-fueled vehicles 
as follows prior to emission testing:
    (A) The manufacturer shall inspect the fuel system to ensure the 
absence of any leaks of liquid or vapor to the atmosphere by applying a 
pressure of 14.50.5 inches of water (3.60.1 kPa) to the fuel system, allowing the pressure to 
stabilize, and isolating the fuel system from the pressure source. 
Following isolation of the fuel system, pressure must not drop more than 
2.0 inches of water (0.5 kPa) in five minutes. If required, the 
manufacturer shall perform corrective action in accordance with 
paragraph (d) of this section and report this action in accordance with 
Sec.86.609-98(d).
    (B) When performing this pressure check, the manufacturer shall 
exercise care to neither purge nor load the evaporative or refueling 
emission control systems.
    (C) The manufacturer may not modify the test vehicle's evaporative 
or refueling emission control systems by component addition, deletion, 
or substitution, except to comply with paragraph (a)(2)(ii) of this 
section if approved in advance by the Administrator.
    (3) The following exceptions to the test procedures in subpart C of 
this part are applicable to Selective Enforcement Audit testing:
    (i) The manufacturer may measure the temperature of the test fuel at 
other than the approximate mid-volume of the fuel tank, as specified in 
Sec.86.107-96(e), and may drain the test fuel from other than the 
lowest point of the fuel tank, provided an equivalent method is used. 
Equivalency documentation shall be maintained by the manufacturer and 
shall be made available to the Administrator upon request.
    (ii) In performing exhaust sample analysis under Sec.86.140, the 
manufacturer shall exercise care to prevent moisture from condensing in 
the sample collection bags.
    (iii) The manufacturer need not comply with Sec.86.142 since the 
records required therein are provided under other provisions of this 
subpart G.
    (iv) In addition to the requirements of subpart C of this part, the 
manufacturer shall prepare gasoline-fueled vehicles as follows prior to 
exhaust emission testing:
    (A) The manufacturer shall inspect the fuel system to ensure the 
absence of any leaks of liquid or vapor to the atmosphere by applying a 
pressure of 14.50.5 inches of water (3.60.1 kPa) to the fuel system allowing the pressure

[[Page 830]]

to stabilize and isolating the fuel system from the pressure source. 
Following isolation of the fuel system, pressure must not drop more than 
2.0 inches of water (0.5 kPa) in five minutes. If required, the 
manufacturer shall perform corrective action in accordance with 
paragraph (d) of this section and report this action in accordance with 
Sec.86.609-98(d).
    (B) When performing this pressure check, the manufacturer shall 
exercise care to neither purge nor load the evaporative or refueling 
emission control system.
    (C) The manufacturer shall not modify the test vehicle's evaporative 
or refueling emission control system by component addition, deletion, or 
substitution, except if approved in advance by the Administrator, to 
comply with paragraph (a)(3)(i) of this section.
    (b)(1) The manufacturer shall not adjust, repair, prepare, or modify 
the vehicles selected for testing and shall not perform any emission 
tests on vehicles selected for testing pursuant to the test order unless 
this adjustment repair, preparation, modification, and/or tests are 
documented in the manufacturer's vehicle assembly and inspection 
procedures and are actually performed or unless these adjustments and/or 
tests are required or permitted under this subpart or are approved in 
advance by the Administrator.
    (2) For 1981 and later model years the Administrator may adjust or 
cause to be adjusted any engine or vehicle parameter which the 
Administrator has determined to be subject to adjustment for new vehicle 
compliance testing (e.g., for certification or Selective Enforcement 
Audit testing) in accordance with Sec.86.081-22(c)(1), to any setting 
within the physically adjustable range of that parameter, as determined 
by the Administrator in accordance with Sec.86.081-22(e)(3)(ii), prior 
to the performance of any tests. However, if the idle speed parameter is 
one which the Administrator has determined to be subject to adjustment, 
the Administrator shall not adjust it to a setting which causes a lower 
engine idle speed than will be possible within the physically adjustable 
range of the idle speed parameter on the vehicle when it has accumulated 
4,000 miles, all other parameters being adjusted identically for the 
purpose of comparison. The Administrator, in making or specifying such 
adjustments, will consider the effect of the deviation from the 
manufacturer's recommended setting on emissions performance 
characteristics as well as the likelihood that similar settings will 
occur on in-use light-duty vehicles or light-duty trucks. In determining 
likelihood, the Administrator will consider factors such as, but not 
limited to, the effect of the adjustment on vehicle performance 
characteristics and surveillance information from similar in-use 
vehicles.
    (c) Prior to performing emission testing pursuant to paragraph (a) 
of this section on an SEA test vehicle, the manufacturer may accumulate 
on each vehicle a number of miles equal to the greater of 4,000 miles, 
or the number of miles the manufacturer accumulated during certification 
on the emission-data vehicle corresponding to the configuration 
specified in the test order.
    (1) Mileage accumulation must be performed in any manner using good 
engineering judgment to obtain emission results representative of normal 
production vehicles. This mileage accumulation must be consistent with 
the new vehicle break-in instructions contained in the applicable 
vehicle owner's manual, if any.
    (2) The manufacturer shall accumulate mileage at a minimum rate of 
300 miles per vehicle during each 24-hour period, unless otherwise 
provided by the Administrator.
    (i) The first 24-hour period for mileage accumulation shall begin as 
soon as authorized vehicle checks, inspections and preparations are 
completed on each vehicle.
    (ii) The minimum mileage accumulation rate does not apply on 
weekends or holidays.
    (iii) If the manufacturer's mileage accumulation target is less than 
the minimum rate specified (300 miles per day), then the minimum daily 
accumulation rate shall be equal to the manufacturer's mileage 
accumulation target.
    (3) Mileage accumulation shall be completed on a sufficient number 
of test vehicles during consecutive 24-hour periods to assure that the 
number

[[Page 831]]

of vehicles tested per day fulfills the requirements of paragraph (g) of 
this section.
    (d) The manufacturer shall not perform any maintenance on test 
vehicles after selection for testing nor shall the Administrator allow 
deletion of any test vehicle from the test sequence, unless requested by 
the manufacturer and approved by the Administrator before any test 
vehicle maintenance of deletion.
    (e) The manufacturer will be allowed 24 hours to ship test vehicles 
from the assembly plant or storage facility to the test facility if the 
test facility is not located at the plant or storage facility or in 
close proximity to the plant or storage facility: Except, that the 
Administrator may approve more time based upon a request by the 
manufacturer accompanied by a satisfactory justification.
    (f) If a vehicle cannot complete the mileage accumulation or 
emission tests because of vehicle malfunction, the manufacturer may 
request the Administrator to authorize the repair of that vehicle or its 
deletion from the test sequence.
    (g) Whenever the manufacturer conducts testing pursuant to a test 
order issued under this subpart, the manufacturer shall notify the 
Administrator within one working day of receipt of the test order, which 
test facility will be used to comply with the test order and the number 
of available test cells at that facility. If no test cells are available 
at the desired facility, the manufacturer must provide alternate testing 
capability satisfactory to the Administrator.
    (1) The manufacturer shall perform a combination of tests pursuant 
to paragraph (a) of this section so that a minimum of four tests are 
performed per 24 hour period, including voided tests, for each available 
test cell.
    (2) The Administrator may approve a longer period based upon a 
request by a manufacturer accompanied by satisfactory justification.
    (h) The manufacturer shall perform test vehicle selection, 
preparation, mileage accumulation, shipping, and testing in such a 
manner as to assure that the audit is performed in an expeditious 
manner.
    (i) The manufacturer may retest any test vehicle after a fail 
decision has been reached in accordance with Sec.86.610-98(d) based on 
the first test on each vehicle; except that the Administrator may 
approve retests at other times during the audit based upon a request by 
the manufacturer accompanied by a satisfactory justification. The 
manufacturer may test each vehicle a total of three times. The 
manufacturer shall test each vehicle the same number of times. The 
manufacturer may accumulate additional mileage on test vehicles before 
conducting retests, subject to the provisions of paragraph (c) of this 
section.

Sec.86.609-98  Calculation and reporting of test results.

    (a) Initial test results are calculated following the test 
procedures specified in Sec.86.608-98(a). Round the initial test 
results to the number of decimal places contained in the applicable 
emission standard expressed to one additional significant figure.
    (b) Final test results for each test vehicle are calculated by 
summing the initial test results derived in paragraph (a) of this 
section for each test vehicle, dividing by the number of times that 
specific test has been conducted on the vehicle, and rounding to the 
same number of decimal places contained in the applicable standard 
expressed to one additional significant figure.
    (c) Final deteriorated test results. (1) For each test vehicle. The 
final deteriorated test results for each light-duty vehicle tested for 
exhaust emissions and/or refueling emissions according to subpart B, 
subpart C, or subpart R of this part are calculated by first multiplying 
or adding, as appropriate, the final test results by or to the 
appropriate deterioration factor derived from the certification process 
for the engine or evaporative/refueling family and model year to which 
the selected configuration belongs, and then by multiplying by the 
appropriate reactivity adjustment factor, if applicable, and rounding to 
the same number of

[[Page 832]]

decimal places contained in the applicable emission standard. For the 
purpose of this paragraph (c), if a multiplicative deterioration factor 
as computed during the certification process is less than one, that 
deterioration factor is one. If an additive deterioration factor as 
computed during the certification process is less than zero, that 
deterioration factor will be zero.
    (2) Exceptions. There are no deterioration factors for light-duty 
vehicle emissions obtained during spitback testing in accordance with 
Sec.86.146. Accordingly, for the fuel dispensing spitback test, the 
term ``final deteriorated test results'' means the final test results 
derived in paragraph (b) of this section for each test vehicle, rounded 
to the same number of decimal places contained in the applicable 
emission standard.
    (d) Within five working days after completion of testing of all 
vehicles pursuant to a test order, the manufacturer shall submit to the 
Administrator a report which includes the following information:
    (1) The location and description of the manufacturer's emission test 
facilities which were utilized to conduct testing reported pursuant to 
this section.
    (2) The applicable standards against which the vehicles were tested.
    (3) Deterioration factors for the selected configuration.
    (4) A description of the vehicle selection method used.
    (5) For each test conducted.
    (i) Test vehicle description including:
    (A) Configuration, engine family, and refueling family 
identification.
    (B) Year, make, build date, and model of vehicle.
    (C) Vehicle Identification Number.
    (D) Miles accumulated on vehicle.
    (ii) Location where mileage accumulation was conducted and 
description of accumulation schedule.
    (iii) Test number, date initial test results, final results and 
final deteriorated test results for all valid and invalid exhaust 
emission tests, and the reason for invalidation.
    (iv) A complete description of any modification, repair, 
preparation, maintenance and/or testing which was performed on the test 
vehicle and:
    (A) Has not been reported pursuant to any other paragraph of this 
subpart; and
    (B) Will not be performed on all other production vehicles.
    (v) Carbon dioxide emission values for all valid and invalid exhaust 
emission tests.
    (vi) Where a vehicle was deleted from the test sequence by 
authorization of the Administrator, the reason for the deletion.
    (vii) Any other information the Administrator may request relevant 
to the determination as to whether the new motor vehicles being 
manufactured by the manufacturer do in fact conform with the regulations 
with respect to which the certificate of conformity was issued.
    (6) The following statement and endorsement:

    This report is submitted pursuant to sections 206 and 208 of the 
Clean Air Act. This Selective Enforcement Audit was conducted in 
complete conformance with all applicable regulations under 40 CFR part 
86 and the conditions of the test order. No emission related change(s) 
to production processes or quality control procedures for the vehicle 
configuration tested have been made between receipt of this test order 
and conclusion of the audit. All data and information reported herein 
is, to the best of

Sec.86.610-98  Compliance with acceptable quality level and passing
and failing criteria for Selective Enforcement Audits.

    (a) The prescribed acceptable quality level is 40 percent.
    (b) A failed vehicle is one whose final deteriorated test results 
pursuant to Sec.86.609-98(c) exceed at least one of the applicable 
emission standards associated with the test procedures pursuant to Sec.
86.608-98(a).
    (c)(1) Pass/fail criteria. The manufacturer shall test vehicles 
comprising the

[[Page 833]]

test sample until a pass decision is reached for all of the pollutants 
associated with all of the test procedures pursuant to Sec.86.608-
98(a) or a fail decision is reached for one of these pollutants. A pass 
decision is reached when the cumulative number of failed vehicles, as 
defined in paragraph (b) of this section, for each pollutant is less 
than or equal to the fail decision number appropriate to the cumulative 
number of vehicles tested. A fail decision is reached when the 
cumulative number of failed vehicles for one pollutant is greater than 
or equal to the fail decision number appropriate to the cumulative 
number of vehicles tested. The pass and fail decision numbers associated 
with the cumulative number of vehicles tested are determined by use of 
the tables in appendix XI of this part appropriate for the annual 
projected sales as made by the manufacturer in its report submitted 
under Sec.600.207-80(a)(2) of this chapter (Automobile Fuel Economy 
Regulations). In the tables in appendix XI of this part, sampling plan 
``stage'' refers to the cumulative number of vehicles tested. Once a 
pass decision has been made for a particular pollutant associated with a 
particular test procedure pursuant to Sec.86.608-98(a), the number of 
vehicles whose final deteriorated test results exceed the emission 
standard for that pollutant may not be considered any further for 
purposes of the audit.
    (2) [Reserved]
    (d) Passing or failing of an SEA audit occurs when the decision is 
made on the last vehicle required to make a decision under paragraph (c) 
of this section.
    (e) The Administrator may terminate testing earlier than required in 
paragraph (c) of this section.

Sec.86.612-97  Suspension and revocation of certificates of conformity.

    (a) The certificate of conformity is immediately suspended with 
respect to any vehicle failing pursuant to Sec.86.610-98(b) effective 
from the time that testing of that vehicle is completed.
    (b) The Administrator may suspend the certificate of conformity for 
a configuration that does not pass a selective enforcement audit 
pursuant to Sec.86.610-98(c) based on the first test, or all tests, 
conducted on each vehicle. This suspension will not occur before ten 
days after failure to pass the audit.
    (c) If the results of vehicle testing pursuant to the requirements 
of this subpart indicate the vehicles of a particular configuration 
produced at more than one plant do not conform to the regulations with 
respect to which the certificate of conformity was issued, the 
Administrator may suspend the certificate of conformity with respect to 
that configuration for vehicles manufactured by the manufacturer in 
other plants of the manufacturer.
    (d) The Administrator will notify the manufacturer in writing of any 
suspension or revocation of a certificate of conformity in whole or in 
part: Except, that the certificate of conformity is immediately 
suspended with respect to any vehicle failing pursuant to Sec.86.610-
98(b) and as provided for in paragraph (a) of this section.
    (e) The Administrator may revoke a certificate of conformity for a 
configuration when the certificate has been suspended pursuant to 
paragraph (b) or (c) of this section if the proposed remedy for the 
nonconformity, as reported by the manufacturer to the Administrator, is 
one requiring a design change(s) to the engine and/or emission control 
system as described in the Application for Certification of the affected 
configuration.
    (f) Once a certificate has been suspended for a failed vehicle as 
provided for in paragraph (a) of this section, the manufacturer must 
take the following actions:
    (1) Before the certificate is reinstated for that failed vehicle--
    (i) Remedy the nonconformity; and
    (ii) Demonstrate that the vehicle's final deteriorated test results 
conform to the applicable emission standards or family particulate 
emission limits, as defined in this part 86 by retesting the vehicle in 
accordance with the requirements of this subpart.
    (2) Submit a written report to the Administrator within thirty days 
after successful completion of testing on the failed vehicle, which 
contains a description of the remedy and test results

[[Page 834]]

for the vehicle in addition to other information that may be required by 
this subpart.
    (g) Once a certificate has been suspended pursuant to paragraph (b) 
or (c) of this section, the manufacturer must take the following actions 
before the Administrator will consider reinstating such certificate:
    (1) Submit a written report to the Administrator which identifies 
the reason for the noncompliance of the vehicles, describes the proposed 
remedy, including a description of any proposed quality control and/or 
quality assurance measures to be taken by the manufacturer to prevent 
the future occurrence of the problem, and states the date on which the 
remedies will be implemented.
    (2) Demonstrate that the engine family or configuration for which 
the certificate of conformity has been suspended does in fact comply 
with the requirements of this subpart by testing vehicles selected from 
normal production runs of that engine family or configuration at the 
plant(s) or the facilities specified by the Administrator, in accordance 
with: the conditions specified in the initial test order pursuant to 
Sec.86.603 for a configuration suspended pursuant to paragraph (b) or 
(c) of this section.
    (3) If the Administrator has not revoked the certificate pursuant to 
paragraph (e) of this section and if the manufacturer elects to continue 
testing individual vehicles after suspension of a certificate, the 
certificate is reinstated for any vehicle actually determined to have 
its final deteriorated test results in conformance with the applicable 
standards through testing in accordance with the applicable test 
procedures.
    (h) Once a certificate for a failed engine family or configuration 
has been revoked under paragraph (e) of this section and the 
manufacturer desires to introduce into commerce a modified version of 
that engine family or configuration, the following actions will be taken 
before the Administrator may issue a certificate for the new engine 
family or configuration:
    (1) If the Administrator determines that the proposed change(s) in 
vehicle design may have an effect on emission performance deterioration 
and/or fuel economy, he/she shall notify the manufacturer within five 
working days after receipt of the report in paragraph (g)(1) of this 
section whether subsequent testing under this subpart will be sufficient 
to evaluate the proposed change(s) or whether additional testing will be 
required.
    (2) After implementing the change(s) intended to remedy the 
nonconformity, the manufacturer shall demonstrate, if the certificate 
was revoked pursuant to paragraph (e) of this section, that the modified 
vehicle configuration does in fact conform with the requirements of this 
subpart by testing vehicles selected from normal production runs of that 
modified vehicle configuration in accordance with the conditions 
specified in the initial test order pursuant to Sec.86.603. The 
Administrator shall consider this testing to satisfy the testing 
requirements of Sec.86.079-32 or Sec.86.079-33 if the Administrator 
had so notified the manufacturer. If the subsequent testing results in a 
pass decision pursuant to the criteria in Sec.86.610-98(c), the 
Administrator shall reissue or amend the certificate, if necessary, to 
include that configuration: Provided, that the manufacturer has 
satisfied the testing requirements specified in paragraph (h)(1) of this 
section. If the subsequent audit results in a fail decision pursuant to 
the criteria in Sec.86.610-98(c), the revocation remains in effect. 
Any design change approvals under this subpart are limited to the 
modification of the configuration specified by the test order.
    (i) A manufacturer may at any time subsequent to an initial 
suspension of a certificate of conformity with respect to a test vehicle 
pursuant to paragraph (a) of this section, but not later than fifteen 
(15) days or such other period as may be allowed by the Administrator 
after notification of the Administrator's decision to suspend or revoke 
a certificate of conformity in whole or in part pursuant to paragraph 
(b), (c) or (e) of this section, request that the Administrator grant 
such manufacturer a hearing as to whether the tests have been properly 
conducted or any sampling methods have been properly applied.

[[Page 835]]

    (j) After the Administrator suspends or revokes a certificate of 
conformity pursuant to this section or notifies a manufacturer of his 
intent to suspend, revoke or void a certificate of conformity under 
Sec.86.007-30(e) or Sec.86.1850, and prior to the commencement of a 
hearing under Sec.86.614, if the manufacturer demonstrates to the 
Administrator's satisfaction that the decision to suspend, revoke or 
void the certificate was based on erroneous information, the 
Administrator shall reinstate the certificate.
    (k) To permit a manufacturer to avoid storing non-test vehicles when 
conducting testing of an engine family or configuration subsequent to 
suspension or revocation of the certificate of conformity for that 
engine family or configuration pursuant to paragraph (b), (c), or (e) of 
this section, the manufacturer may request that the Administrator 
conditionally reinstate the certificate for that engine family or 
configuration. The Administrator may reinstate the certificate subject 
to the condition that the manufacturer consents to recall all vehicles 
of that engine family or configuration produced from the time the 
certificate is conditionally reinstated if the engine family or 
configuration fails the subsequent testing and to remedy any 
nonconformity at no expense to the owner.

Sec.86.884-5  Test procedures.

    The procedures described in this and subsequent sections will be the 
test program to determine the conformity of engines with the standards 
set forth in Sec.86.084-11(b).
    (a) The test consists of a prescribed sequence of engine operating 
conditions on an engine dynamometer with continuous examination of the 
exhaust gases. The test is applicable equally to controlled engines 
equipped with means for preventing, controlling, or eliminating smoke 
emissions and to uncontrolled engines.

[[Page 836]]

    (b) The test is designed to determine the opacity of smoke in 
exhaust emissions during those engine operating conditions which tend to 
promote smoke from diesel vehicles.
    (c) The test procedure begins with a preconditioned engine which is 
then run through preloading and preconditioning operations. After an 
idling period, the engine is operated through acceleration and lugging 
modes during which smoke emission measurements are made to compare with 
the standards. The engine is then returned to the idle condition and the 
acceleration and lugging modes are repeated. Three consecutive sequences 
of acceleration and lugging constitutes the full set of operating 
conditions for smoke emission measurement.
    (d)(1) Except in cases of component mulfunction or failure, all 
emission control systems installed on, or incorporated in, a new motor 
vehicle engine shall be functioning during all procedures in this 
subpart.
    (2) Maintenance to correct component malfunction or failure shall be 
authorized in accordance with Sec.86.084-25.

Sec.86.884-7  Dynamometer operation cycle for smoke emission tests.

    (a) The following sequence of operations shall be performed during 
engine dynamometer testing of smoke emissions, starting with the 
dynamometer preloading determined and the engine preconditioned (Sec.
86.884-12(c)).
    (1) Idle Mode. The engine is caused to idle for 5.0 to 5.5 minutes 
at the manufacturer's recommended curb idle speed. The dynamometer 
controls shall be set to provide the speed and load necessary to comply 
with the heavy-duty ``curb idle'' definition per Sec.86.084-2, in 
accordance with predominant engine application.
    (2) Acceleration mode. (i) The engine speed shall be increased to 
200 50 rpm above the measured free idle speed 
measured at the point where the throttle begins to move from part-
throttle to the full throttle position. The speed anywhere during this 
mode should not exceed this checkpoint speed by more than 50 rpm. The 
duration of this first acceleration shall be three seconds or less 
measured from the point where the speed first begins to increase above 
idle to the point where the throttle reaches full open position.
    (ii) Immediately upon completion of the mode specified in paragraph 
(a)(2)(i) of this section, the throttle shall be moved rapidly to, and 
held in, the fully open position. The inertia of the engine and the 
dynamometer, or alternately a preselected dynamometer load, shall be 
used to control the acceleration of the engine so that the speed 
increases to 85 percent of the rated speed in 5 1.5 seconds. This acceleration shall be linear within 
100 rpm as specified in Sec.86.884-13(c).
    (iii) After the engine reaches the speed required in paragraph 
(a)(2)(ii) of this section the throttle shall be moved rapidly to, and 
held in, the fully closed position. Immediately after the throttle is 
closed, the preselected load required to perform the acceleration in 
paragraph (a)(2)(iv) of this section shall be applied. For electric 
motoring dynamometer operation in speed mode, the deceleration shall be 
performed in 21.5 seconds.
    (iv) When the engine decelerates to the intermediate speed (within 
50 rpm), the throttle shall be moved rapidly to, and held in, the fully 
open position. The preselected dynamometer load which was applied during 
the preceding transition period shall be used to control the 
acceleration of the engine so that the speed increases to at least 95 
percent of the rated speed in 10 2 seconds.
    (v) For electric dynamometer operation in speed mode, motoring 
assist may be used to offset excessive dynamometer inertia load when 
necessary. No negative flywheel torque shall occur during any of the 
three acceleration modes in paragraph (a)(2) of this section except for 
a maximum of 10ft-lbs. for the first 0.5 second of the mode.
    (3) Lugging mode. (i) Immediately upon the completion of the 
preceding acceleration mode, the dynamometer

[[Page 837]]

controls shall be adjusted to permit the engine to develop maximum 
horsepower at rated speed. This transition period shall be 50 to 60 
seconds in duration. During the last 10 seconds of this period, the 
average engine speed shall be maintained within 50 rpm of the rated

speed is reduced to the intermediate speed. This lugging operation shall 
be performed smoothly over a period of 355 seconds. The rate of slowing 
of the engine shall be linear, within 100 rpm, as specified in Sec.
86.884-13(c).
    (4) Engine unloading. Within five seconds of completing the 
preceding lugging mode, the dynamometer and engine controls shall be 
returned to the idle position described in paragraph (a)(1) of this 
section. The engine must be at free idle condition within one minute 
after completion of the lugging mode.

    (a) Schematic drawing. The Figure I84-1 is a schematic drawing of 
the optical system of the light extinction meter.
[GRAPHIC] [TIFF OMITTED] TR06OC93.182

    (b) Equipment. The following equipment shall be used in the system.
    (1) Adapter--the smokemeter optical unit may be mounted on a fixed 
or movable frame. The normal unrestricted shape of the exhaust plume 
shall not be modified by the adaptor, the meter, or any ventilatory 
system used to remove the exhaust from the test site.
    (2) Smokemeter (light extinction meter)--continuous recording, full-
flow light obscuration meter.
    (i) It is positioned so that a built-in light beam traverses the 
exhaust smoke plume at right angles to the axis of the exhaust stream.
    (ii) The smokemeter light source shall be an incandescent lamp with 
a color temperature range of 2800K to 3250K, or a light source with a 
spectral peak between 550 to 570 nanometers.
    (iii) The light output is collimated to a beam with a maximum 
diameter of 1.125 inches and an included angle of divergence within a 
6[deg] included angle.
    (iv) The light detector shall be a photocell or photodiode. If the 
light source is an incandescent lamp, the detector shall have a spectral 
response similar to the photopic curve of the human eye (a maximum 
response in the range of 550 to 570 nanometers, to less than 4 percent 
of that maximum response below 430 nanometers and above 680 nanometers).
    (v) A collimating tube with apertures equal to the beam diameter is 
attached to the detector to restrict the viewing angle of the detector 
to within a 16[deg] included angle.
    (vi) An amplified signal corresponding to the amount of light

[[Page 839]]

blocked is recorded continuously on a remote recorder.
    (vii) An air curtain across the light source and detector window 
assemblies may be used to minimize deposition of smoke particles on 
those surfaces provided that it does not measurably affect the opacity 
of the plume.
    (viii) The smokemeter consists of two units; an optical unit and a 
remote control unit.
    (ix) Light extinction meters employing substantially identical 
measurement principles and producing substantially equivalent results, 
but which employ other electronic and optical techniques, may be used 
only after having been approved in advance by the Administrator.
    (3) Recorder--a continuous recorder, with variable chart speed over 
a minimal range of 0.5 to 8.0 inches per minute (or equivalent) and an 
automatic marker indicating 1-second intervals continuously records the 
exhaust gas opacity, engine rpm and throttle position.
    (i) The recorder is equipped to indicate only when the throttle is 
in the fully open or fully closed position.
    (ii) The recorder scale for opacity is linear and calibrated to read 
from 0 to 100 percent opacity full scale.
    (iii) The opacity trace has a resolution within one percent opacity.
    (iv) The recorder scale for engine rpm is linear and has a 
resolution of 30 rpm.
    (v) The throttle position trace clearly indicates when the throttle 
is in the fully open and fully closed positions.
    (vi) Any means other than a strip-chart recorder may be used 
provided it produces a permanent visual data record of quality equal to 
or better than that described above (e.g., tabulated data, traces, or 
plots).
    (4) The recorder used with the smokemeter shall be capable of full-
scale deflection in 0.5 second or less. The smokemeter-recorder 
combination may be damped so that signals with a frequency higher than 
10 cycles per second are attenuated. A separate lowpass electronic 
filter with the following performance characteristics may be installed 
between the smokemeter and the recorder to achieve the high-frequency 
attenuation:
    (i) Three decibel point--10 cycles per second.
    (ii) Insertion loss--zero 0.5 decibel.
    (iii) Selectivity--12 decibels per octave above 10 cycles per 
second.
    (iv) Attenuation--27 decibels down at 40 cycles per second minimum.
    (5) In lieu of the use of chart recorders, automatic data collection 
equipment may be used to record all required data. Automatic data 
processing equipment may then be used to perform the data analysis 
specified in Sec.86.884-13. The automatic data collection equipment 
must be capable of sampling at least two records per second.
    (c) Assembling equipment. (1) The optical unit of the smokemeter 
shall be mounted radially to the exhaust pipe so that the measurement 
will be made at right angles to the axis of the exhaust plume. For an 
end-of-line smokemeter the distance from the optical centerline to the 
exhaust pipe outlet shall be 1 0.25 inch. The full 
flow of the exhaust stream shall be centered between the source and the 
detector apertures (or windows and lenses) and on the axis of the light 
beam.
    (2) Power shall be supplied to the control unit of the smokemeter in 
time to allow at least 15 minutes for stabilization prior to testing.

starts when the preceding acceleration mode has been completed and ends 
when the engine speed is 50 rpm below the rated speed and the provisions 
of Sec.86.884-7 (a)(3)(i) are met.
    (7) The lugging mode specified in Sec.86.884-7(a)(3)(ii) starts

    (1) Starting at the beginning of the first acceleration, as defined 
in paragraph (a)(2) of this section, and stopping at the end of the 
second acceleration, as defined in paragraph (a)(3) of this section, 
divide the smoke trace into half-second intervals. Similarly, subdivide 
into half-second intervals the third acceleration mode and the lugging 
mode as defined by paragraphs (a) (5) and (7) respectively, of this 
section.
    (2) Determine the average smoke reading during each half-second 
interval.
    (3) Locate and record the 15 highest half-second readings during the 
acceleration mode of each dynamometer cycle.
    (4) Locate and record the five highest half-second readings during 
the lugging mode of each dynamometer cycle.

[[Page 843]]

    (5) Examine the average half-second values which were determined in 
paragraphs (d)(3) and (d)(4) of this section and record the three 
highest values for each dynamometer cycle.
    (6) This smoke trace analysis may be performed by direct analysis of 
the recorder traces, or by computer analysis of data collected by 
automatic data collection equipment.

Sec.86.884-14  Calculations.

    (a) If the measured half-second opacity values were obtained with a 
smokemeter with an optical path length different than shown in the table 
in Sec.86.884-8(c), then convert the measured half-second values or 
the original instantaneous values to the appropriate equivalent optical 
path length values specified in the table. Convert the opacity values 
according to the following equations:

[GRAPHIC] [TIFF OMITTED] TR15JA04.001

Lm and Ls must use consistent units in the above 
equation

Where:

Nm = Measured half-second value for conversion, percent 
          opacity
Lm = Measuring smokemeter optical path length, meters
Ls = Standard optical path length corresponding with engine 
          power, n
Ns = Standard half-second value, percent opacity

    (b) Average the 45 readings in Sec.86.884-13(d)(3) or the 
equivalent converted values from paragraph (a) of this section if 
appropriate, and designate the value as ``A''. This is the value for the 
engine acceleration mode.
    (c) Average the 15 readings in Sec.86.884-13(d)(4) or the 
equivalent converted values from paragraph (a) of this section if 
appropriate, and designate the value as ``B''. This is the value for the 
engine lugging mode.
    (d) Average the 9 readings in Sec.86.884-13(d)(5) or the 
equivalent converted values from paragraph (a) of this section if 
appropriate, and designate the value as ``C''. This is the value for the 
peaks in either mode.
    (e)(1) If multiple smokemeters were used, the half-second values for 
each mode from each smokemeter shall be combined and the calculated 
average based upon the total number of combined values.
    (2) For example, if two smokemeters were used for acceleration mode 
data, 45 half-second values in each data set from both smokemeters would 
be combined to form a data set of 90 values, which would then be 
averaged.

Sec.86.1103-2016  Criteria for availability of nonconformance 
penalties.

    (a) General. This section describes the three criteria EPA will use 
to use to evaluate whether NCPs are appropriate under the Clean Air Act 
for a given pollutant and a given subclass of heavy-duty engines and 
heavy-duty vehicles. Together, these criteria evaluate the likelihood 
that a manufacturer will be technologically unable to meet a standard on 
time. Note that since the first two of these criteria are intended to 
address the question of whether a given standard creates the possibility 
for this to occur, they are evaluated before the third criterion that 
addresses the likelihood that the possibility will actually happen.
    (b) Criteria. We will establish NCPs for a given pollutant and 
subclass when we find that each of the following criteria is met:

    (1) There is a new or revised emission standard is more stringent 
than the previous standard for the pollutant, or an existing standard 
for that pollutant has become more difficult to achieve because of a new 
or revised standard. When evaluating this criterion, EPA will consider a 
new or revised standard to be ``new'' or ``revised'' until the point at 
which all manufacturers already producing U.S.-directed engines or 
vehicles within the subclass have achieved full compliance with the 
standard. For purposes of this criterion, EPA will generally not 
consider compliance using banked emission credits to be ``full 
compliance''.
    (2) Substantial work is required to meet the standard for which the 
NCP is offered, as evaluated from the point at which the standard was 
adopted or revised (or the point at which the standard became more 
difficult meet because another standard was adopted or revised). 
Substantial work, as used in this paragraph (b)(2), means the 
application of technology not previously used in an engine or vehicle 
class or subclass, or the significant modification of existing 
technology or design parameters, needed to bring the vehicle or engine 
into compliance with either the more stringent new or revised standard 
or an existing standard which becomes more difficult to achieve because 
of a new or revised standard. Note that where this criterion is 
evaluated after any of the work has been completed, the criterion would 
be interpreted as whether or not substantial work was required to meet 
the standard.
    (3) There is or is likely to be a technological laggard for the 
subclass. Note that a technological laggard is a manufacturer that is 
unable to meet the standard for one or more products within the subclass 
for technological reasons.
    (c) Evaluation. (1) We will generally evaluate these criteria in 
sequence. Where we find that the first criterion has not been met, we 
will not consider the other two criteria. Where we find that the first 
criterion has been met but not the second, we will not consider the 
third criterion. We may announce our findings separately or 
simultaneously.
    (2) We may consider any available information in making our 
findings.
    (3) Where we are uncertain whether the first and/or second criteria 
have been met, we may presume that they have been met and make our 
decision based solely on whether or not the third criterion has been 
met.
    (4) Where we find that a manufacturer will fail to meet a standard 
but are uncertain whether the failure is a technological failure, we may 
presume

[[Page 846]]

that the manufacturer is a technological laggard.

[81 FR 73980, Oct. 25, 2016]



Sec.86.1104-2016  Determination of upper limits.

    EPA shall set a separate upper limit for each phase of NCPs and for 
each service class.
    (a) Except as provided in paragraphs (b), (c) and (d) of this 
section, the upper limit shall be set as follows:
    (1) The upper limit applicable to a pollutant emission standard for 
a subclass of heavy-duty engines or heavy-duty vehicles for which an NCP 
is established in accordance with Sec.86.1103-87, shall be the 
previous pollutant emission standard for that subclass.
    (2) If a manufacturer participates in any of the emissions 
averaging, trading, or banking programs, and carries over certification 
of an engine family from the prior model year, the upper limit for that 
engine family shall be the family emission limit of the prior model 
year, unless the family emission limit is less than the upper limit 
determined in paragraph (a)(1) of this section.
    (b) If no previous standard existed for the pollutant under 
paragraph (a) of this section, the upper limit will be developed by EPA 
during rulemaking.
    (c) EPA may set the upper limit during rulemaking at a level below 
the level specified in paragraph (a) of this section if we determine 
that a lower level is achievable by all engines or vehicles in that 
subclass.
    (d) EPA may set the upper limit at a level above the level specified 
in paragraph (a) of this section if we determine that such level will 
not be achievable by all engines or vehicles in that subclass.

Sec.86.1106-87  Production compliance auditing.

    For a model year in which upper limits for heavy-duty engine or 
heavy-duty vehicle emission standards for one or more exhaust pollutants 
are specified in Sec.86.1105-87, a manufacturer may elect to conduct a 
Production Compliance Audit (PCA) for each engine or vehicle 
configuration satisfying the following conditions:
    (a) Certification test results, pursuant to Sec.86.082-23, exceed 
the emission standard for a particular pollutant but do not exceed the 
upper limit established for that pollutant. In that event, the 
manufacturer will be offered a qualified certificate of conformity 
allowing for the introduction into commerce of the specified engine 
family, Provided, That:
    (1) The manufacturer must agree to conduct a PCA of those engines or 
vehicles;
    (2) PCA testing must be conducted on the same configurations that 
exceeded the standard in certification. In lieu of that requirement, the 
Administrator may approve testing of a greater or lesser number of 
configurations provided the manufacturer agrees to pay the NCP 
determined from the CL of

[[Page 850]]

each tested configuration for that configuration and for other non-
tested configurations that have similar emission characteristics. If an 
acceptable showing of similar emission characteristics is not made, the 
highest CL of the configurations tested will apply to all non-tested 
configurations exceeding the standard.
    (3) The selection of engines or vehicles for PCA testing must be 
initiated no later than five (5) days after the start of assembly-line 
production of the specified engine or vehicle configuration, unless that 
period is extended by the Administrator;
    (4) The manufacturer must agree:
    (i) To pay the NCP amount calculated as a result of PCA testing on 
each engine or vehicle, unless the manufacturer successfully challenges 
the Administrator's determination of the compliance level or penalty 
calculation or both under Sec.86.1115-87(c);
    (ii) To recall any engines or vehicles introduced into commerce, 
without invoking the procedural requirements of section 207(c) of the 
Clean Air Act, if the compliance level for the engine or vehicle 
configuration of (a)(2) exceeds the upper limit as determined by the 
PCA;
    (5) If the compliance level determined in the PCA is below the 
emission standard, no NCP will be offered, and all appropriate 
qualifications will be removed from the qualified certificate of 
conformity.
    (b) An engine or vehicle configuration fails a Selective Enforcement 
Audit (SEA) under subpart K of 40 CFR part 86 with respect to the 
standard for a particular pollutant but does not fail with respect to 
the upper limit established for that pollutant, and no NCP has been 
previously assessed for that configuration, Provided, That:
    (1) The manufacturer must submit a written report to the 
Administrator within five (5) days after failure to pass the audit 
containing the following:
    (i) A statement that the manufacturer does not intend, at that time, 
to make any engine and/or emission control system design changes that 
may remedy the nonconformity; and
    (ii) A request from the manufacturer to conduct the PCA, including 
the date the testing will begin;
    (2) Failure to submit the report within five (5) days after the SEA 
failure will result in the forfeiture of the NCP option, unless a 
satisfactory justification for the delay is provided to the 
Administrator;
    (3) The selection of any required engines or vehicles for PCA 
testing must be initiated no later than ten (10) days after the SEA 
failure unless extended by the Administrator; otherwise, the 
manufacturer may forfeit the option to elect an NCP;
    (4) PCA testing must be conducted on the same configuration that 
failed the SEA;
    (5) Test results from the SEA, together with any additional test 
results required during the PCA, will be used in establishing a 
compliance level for the configuration pursuant to Sec.86.1112-87(a); 
and
    (6) The manufacturer, upon approval by the Administrator to conduct 
a PCA on a failed SEA engine or vehicle configuration, must agree:
    (i) To pay the NCP amount calculated as a result of PCA testing on 
each engine or vehicle introduced into commerce after the tenth day of 
the SEA failure, unless the manufacturer successfully challenges the 
Administrator's determination of the compliance level or penalty 
calculation or both under Sec.86.1115-87(c);
    (ii) To recall any engines or vehicles introduced into commerce 
after the tenth day of the SEA failure, without invoking the procedural 
requirements of section 207(c) of the Clean Air Act, if the compliance 
level of the engine or vehicle configuration exceeds the upper limit as 
determined by the PCA.
    (c) An engine or vehicle configuration, for which an NCP has been 
previously assessed for a particular pollutant, either passes an SEA 
with respect to the particular pollutant standard, fails an SEA with 
respect to the particular pollutant standard but not the previous 
compliance level, or fails an SEA with respect to the previous 
compliance level but not the associated upper limit, Provided, That:
    (1) The manufacturer must submit a written statement to the 
Administrator within five (5) days of the conclusion of the SEA 
requesting a PCA, including the date the PCA testing will

[[Page 851]]

begin; otherwise, the manufacturer forfeits the option to establish a 
new compliance level;
    (2) The selection of any required engines or vehicles for PCA 
testing must be initiated no later than ten (10) days after the 
conclusion of the SEA unless the period is extended by the 
Administrator; otherwise, the manufacturer forfeits the option to 
establish a new compliance level;
    (3) PCA testing must be conducted on the same configuration tested 
during the SEA, and all conditions in the SEA test order must apply to 
the PCA;
    (4) Test results for the SEA, together with any additional test 
results required during the PCA, will be used in establishing a new 
compliance level for the configuration pursuant to Sec.86.1112-87(a);
    (5) The manufacturer must agree:
    (i) To pay the NCP amount calculated as a result of PCA testing on 
each engine or vehicle introduced into commerce after the tenth day of 
the conclusion of the SEA, unless the manufacturer successfully 
challenges the Administrator's determination of the compliance level or 
penalty calculation or both under Sec.86.1115-87(c);
    (ii) To recall any engines or vehicles introduced into commerce 
after the tenth day after the conclusion of the SEA, without invoking 
the procedural requirements of section 207(c) of the Clean Air Act, if 
the engine or vehicle configuration exceeds the upper limit as 
determined by the PCA;
    (6) A previously assessed NCP will be terminated and no NCP will be 
established as a result of the new PCA if the compliance level is 
determined to be below the applicable emission standards.
    (d) The implementation of a production running change that causes 
the emission level for a particular pollutant to be either above the 
emission standard but below the associated upper limit for a vehicle or 
engine configuration for which an NCP has not been previously assessed, 
or below the associated upper limit for a vehicle or engine 
configuration for which an NCP has been previously assessed, regardless 
of the previous compliance level. In that event, the manufacturer will 
be offered a qualified certificate of conformity allowing for the 
introduction into commerce of the engine or vehicle configuration 
resulting from the running change, Provided, That:
    (1) The manufacturer must submit a written report to the 
Administrator outlining the reason for the running change and the date 
the manufacturer will begin PCA testing;
    (2) The manufacturer must agree:
    (i) To pay the NCP amount calculated as a result of PCA testing on 
each engine or vehicle, unless the manufacturer successfully challenges 
the Administrator's determination of compliance level or penalty 
calculation or both under Sec.86.1115-87(c);
    (ii) To recall any engines or vehicles introduced into commerce, 
without invoking the procedural requirements of section 207(c) of the 
Clean Air Act, if the engine or vehicle configuration exceeds the upper 
limit as determined by the PCA;
    (3) The selection of engines or vehicles for PCA testing must be 
initiated no later than five (5) days after the start of assembly line 
production of the engine or vehicle configuration resulting from the 
running change unless that period is extended by the Administrator; and
    (4) If the compliance level is determined to be below the applicable 
emission standard, a previously assessed NCP will be terminated, an NCP 
will not be established as a result of the PCA testing, and all 
qualifications will be removed from the qualified certificate of 
conformity.
    (e) The following requirements are applicable to each PCA under this 
subpart.
    (1) The manufacturer shall make the following documents available to 
EPA Enforcement Officers upon request;
    (i) A properly filed and current application for certification, 
following the format prescribed by the EPA for the appropriate model 
year; and
    (ii) A copy of the shop manual and dealer service bulletins for the 
configurations being tested.
    (2) Only one mechanic at a time per engine or vehicle shall make 
authorized checks, adjustments, or repairs, unless a particular check, 
adjustment, or repair requires a second mechanic as

[[Page 852]]

indicated in the shop manual or dealer service bulletins.
    (3) A mechanic shall not perform any check, adjustment, or repair 
without an Enforcement Officer present unless otherwise authorized.
    (4) The manufacturer shall utilize only those tools and test

of how the facility operates and to answer his or her questions. Any 
employee whom an EPA Enforcement Officer requests the manufacturer to 
cause to appear for questioning will be entitled to be accompanied, 
represented and advised by counsel.



Sec.86.1110-87  Sample selection.

    (a) Engines or vehicles comprising a test sample which are required 
to be tested pursuant to a PCA in accordance with this subpart will be 
selected at the location and in the manner specified by EPA. If a 
manufacturer determines that the test engines or vehicles cannot be 
selected in the manner specified by EPA, an alternative selection 
procedure may be employed, provided that the manufacturer requests 
approval of the alternative procedure in

[[Page 855]]

advance of the start of test sample selection and that the Administrator 
approves the procedure.
    (b) The manufacturer shall have assembled the test engines or 
vehicles of the configuration selected for testing using its normal mass 
production processes for engines or vehicles to be distributed into 
commerce. In the case of heavy-duty engines, if the test engines are 
selected at a location where they do not have their operational and 
emission control systems installed, EPA will specify the manner and 
location for selection of components to complete assembly of the 
engines. The manufacturer shall assemble these components onto the test 
engines using normal assembly and quality control procedures as 
documented by the manufacturer.
    (c) No quality control, testing, or assembly procedures will be used 
on the completed test engine or vehicle or any portion thereof, 
including parts and subassemblies, that will not be used during the 
production and assembly of all other engines or vehicles of that 
configuration.
    (d) The EPA Enforcement Officers may specify that they, rather than 
the manufacturer, will select the test engines or vehicles.
    (e) The order in which test engines or vehicles are selected 
determines the order in which test results are to be used in applying 
the PCA testing plan in accordance with Sec.86.1112-87.
    (f) The manufacturer shall keep on hand all engines or vehicles 
comprising the test sample until such time as a compliance level is 
determined in accordance with Sec.86.1112-87(a) except that the 
manufacturer may ship any tested engine or vehicle which has not failed 
in accordance with Sec.86.1112-87(f)(1). However, once the 
manufacturer ships any test engine or vehicle, it relinquishes the 
prerogative to conduct retests as provided in Sec.86.1111-87(i).



Sec.86.1111-87  Test procedures for PCA testing.

    (a)(1) For heavy-duty engines, the prescribed test procedure for PCA 
testing is the Federal Test Procedure as described in subparts N, I, and 
P of this part.
    (2) For heavy-duty vehicles, the prescribed test procedure for PCA 
testing is described in subpart M of this part.
    (3) For light-duty trucks, the prescribed test procedure for PCA 
testing is the Federal Test Procedure as described in subparts B and P 
of this part.
    (4) During the testing of heavy-duty diesel engines, the 
manufacturer shall decide for each engine, prior to the start of the 
initial cold cycle, whether the measurement of background particulate is 
required for the cold and hot cycles to be valid. The manufacturer may 
choose to have different requirements for the cold and hot cycles. If a 
manufacturer chooses to require the measurement of background 
particulate, failure to measure background particulate shall void the 
test cycle regardless of the test results. If a test cycle is void, the 
manufacturer shall retest using the same validity requirements of the 
initial test.
    (5) When testing light-duty trucks, the following exceptions to the 
test procedures in subpart B are applicable:
    (i) The manufacturer may use gasoline test fuel meeting the 
specifications of paragraph (a) of Sec.86.113 for mileage 
accumulation. Otherwise, the manufacturer may use fuels other than those 
specified in this section only with advance approval of the 
Administrator.
    (ii) The manufacturer may measure the temperature of the test fuel 
at other than the approximate midvolume of the fuel tank, as specified 
in paragraph (a) of Sec.86.131, and may drain the test fuel from other 
than the lowest point of the fuel tank, as specified in paragraph (b) of 
Sec.86.131, with the advance approval of the Administrator.
    (iii) The manufacturer may perform additional preconditioning on PCA 
test vehicles other than the preconditioning specified in Sec.86.132 
only if the additional preconditioning has been performed on 
certification test vehicles of the same configuration.
    (iv) The manufacturer shall perform the heat build procedure 11 to 
34 hours following vehicle preconditioning rather than according to the 
time period specified in paragraph (a) of Sec.86.133.
    (v) The manufacturer may substitute slave tires for the drive wheel 
tires on

[[Page 856]]

the vehicle as specified in paragraph (e) of Sec.86.135, provided that 
the slave tires are the same size as the drive wheel tires.
    (vi) The cold start exhaust emission test described in Sec.86.137 
shall follow the heat build procedure described in Sec.86.133 by not 
more than one hour.
    (vii) In performing exhaust sample analysis under Sec.86.140:
    (A) When testing diesel vehicles, the manufacturer shall allow a 
minimum of 20 minutes warm-up for the HC analyzer, and a minimum of 2 
hours warm-up for the CO, CO2 and NOX analyzers. 
[Power is normally left on for infrared and chemiluminescent analyzers. 
When not in use, the chopper motors of the infrared analyzers are turned 
off and the phototube high voltage supply to the chemiluminescent 
analyzers is placed in the standby position.]
    (B) The manufacturer shall exercise care to prevent moisture from 
condensing in the sample collection bags.
    (viii) The manufacturer need not comply with Sec.86.142, since the 
records required therein are provided under other provisions of this 
subpart.
    (ix) In addition to the requirements of subpart B of this part, the 
manufacturer shall prepare gasoline-fueled vehicles as follows prior to 
exhaust emission testing:
    (A) The manufacturer shall inspect the fuel system to insure the 
absence of any leaks of liquid or vapor to the atmosphere by applying a 
pressure of 14.5 0.5 inches of water to the fuel 
system, allowing the pressure to stabilize, and isolating the fuel 
system from the pressure source. Following isolation of the fuel system, 
pressure must not drop more than 2.0 inches of water in 5 minutes. If 
required, the manufacturer shall perform corrective action in accordance 
with paragraph (d) of this section.
    (B) When performing this pressure check, the manufacturer shall 
exercise care to neither purge nor load the evaporative emission control 
system.
    (C) The manufacturer shall not modify the test vehicle's evaporative 
emission control system by component addition, deletion, or 
substitution, except to comply with paragraph (a)(4)(ii) of this section 
if approved in advance by the Administrator.
    (b)(1) The manufacturer shall not adjust, repair, prepare, or modify 
the engines or vehicles selected for testing and shall not perform any 
emission tests on engines or vehicles selected for testing pursuant to a 
PCA request unless the adjustment, repair, preparation, modification, or 
tests are documented in the manufacturer's engine or vehicle assembly 
and inspection procedures and are actually performed on all engines or 
vehicles produced or unless these adjustments or tests are required or 
permitted under this subpart or are approved in advance by the 
Administrator.
    (2) For 1984 and later model years the Administrator may adjust or 
cause to be adjusted any engine parameter which the Administrator has 
determined to be subject to adjustment for certification, Selective 
Enforcement Audit and Production. Compliance Audit testing in accordance 
with Sec.86.084-22(e)(1), to any setting within the physically 
adjustable range of that parameter, as determined by the Administrator 
in accordance with Sec.86.084-2(e)(3)(ii), prior to the performance of 
any tests. However, if the idle speed parameter is one which the 
Administrator has determined to be subject to adjustment, the 
Administrator shall not adjust it to any setting which causes a lower 
engine idle speed than would have been possible within the physically 
adjustable range of the idle speed parameter if the manufacturer had 
accumulated 125 hours of service on the engine or 4,000 miles on the 
vehicle under paragraph (c) of this section, all other parameters being 
identically adjusted for the purpose of the comparison. The manufacturer 
may be requested to supply information to establish such an alternative 
minimum idle speed. The Administrator, in making or specifying these 
adjustments, may consider the effect of the deviation from the 
manufacturer's recommended setting on emissions performance 
characteristics as well as the likelihood that similar settings will 
occur on in-use heavy-duty engines or light-duty trucks. In determining 
likelihood, the Administrator may consider factors such as, but not 
limited

[[Page 857]]

to, the effect of the adjustment on engine or vehicle performance 
characteristics and surveillance information from similar in-use engines 
or vehicles.
    (c) Prior to performing emission testing on a PCA test engine, the 
manufacturer may accumulate on each engine a number of hours of service 
equal to the greater of 125 hours or the number of hours the 
manufacturer accumulated during certification on the emission-data 
engine corresponding to the configuration tested during PCA. Prior to 
performing emission testing on a PCA test vehicle, the manufacturer may 
accumulate a number of miles equal to the greater of 4,000 miles or the 
number of miles the manufacturer accumulated during certification on the 
emission-data vehicle corresponding to the configuration tested during 
PCA. Service or mileage accumulation may be performed in any manner the 
manufacturer desires.
    (d) No maintenance shall be performed on test engines or vehicles 
after selection for testing nor will any test engine or vehicle 
substitution or replacement be allowed, unless requested of and approved 
by the Administrator in advance of the performance of any maintenance or 
engine or vehicle substitution.
    (e) The manufacturer shall expeditiously ship test engines or 
vehicles from the point of selection to the test facility or other 
location to meet any other requirements of this subpart. If the test 
facility is not located at or in close proximity to the point of 
selection, the manufacturer shall assure that test engines or vehicles 
arrive at the test facility within 24 hours of selection, except that 
the Administrator may approve more time based upon a request by the 
manufacturer accompanied by a satisfactory justification.
    (f) If an engine or vehicle cannot complete the service or mileage 
accumulation or emission tests because of engine or vehicle malfunction, 
the manufacturer may request that the Administrator authorize the repair 
of the engine or vehicle. If the engine or vehicle cannot be repaired 
expeditiously, EPA may delete it from the test sequence.
    (g)(1) Heavy-duty engine manufacturers with projected sales bound 
for the United States market for that year of 30,000 or greater, as made 
in their respective Applications for Certification, shall complete 
emission testing at their testing facility on a minimum of two engines 
per 24 hour period, including voided tests.
    (2) Heavy-duty engine manufacturers with projected sales bound for 
the United States market for that year of less than 30,000, as made in 
their respective Applications for Certification, Shall complete emission 
testing at one engine per 24 hour period, including voided tests.
    (3) Light-duty truck manufacturers shall complete emission testing 
on a minimum of four vehicles per 24 hour period, including voided 
tests.
    (4) The Administrator may approve a longer period of time for 
conducting emission tests based upon a request by a manufacturer 
accompanied by a satisfactory justification.
    (h) The manufacturer shall perform test engine or vehicle selection, 
shipping, preparation, service or mileage accumulation, and testing in 
such a manner as to insure that the audit is performed in an expeditious 
manner.
    (i) The manufacturer may retest any engines or vehicles tested 
during a Production Compliance Audit once a compliance level has been 
established in accordance with Sec.86.1112-87 based on the first test 
on each engine or vehicle. The Administrator may approve retesting at 
other times based upon a request by the manufacturer accompanied by a 
satisfactory justification. The manufacturer may test each engine or 
vehicle a total of three times. The manufacturer shall test each engine 
or vehicle the same number of times. The manufacturer may accumulate 
additional service or mileage before conducting a retest, subject to the 
provisions of paragraph (c) of this section.

Sec.86.1112-87  Determining the compliance level and reporting of test
results.

    (a) A manufacturer that has elected to conduct a PCA in accordance 
with

[[Page 858]]

Sec.86.1106-87 may establish the compliance level for a pollutant for 
any engine or vehicle configuration by using the primary PCA sampling 
plan or either of two optional reduced PCA sampling plans (the fixed 
reduced sampling plan or the sequential reduced sampling plan) described 
below. A manufacturer that uses either of the two optional reduced PCA 
sampling plans may elect to continue testing and establish a compliance 
level under the primary PCA sampling plan.
    (1) A manufacturer that elects to conduct a PCA for a pollutant 
using the primary PCA sampling plan shall:
    (i) Conduct emission tests on 24 engines or vehicles in accordance 
with Sec.86.1111-87 for the pollutants for which the PCA was 
initiated. If the PCA follows an SEA failure, the number of additional 
tests conducted shall be the difference between 24 and the number of 
engines or vehicles tested in the SEA. If 24 or more engines or vehicles 
were tested in the SEA, no additional tests shall be conducted; and
    (ii) Rank the final deteriorated test results, as defined by 
paragraph (e) of this section, obtained for that pollutant in order from 
the lowest to the highest value. If the PCA follows an SEA failure, all 
SEA test results for that pollutant shall be included in this ranking.
    (iii) The compliance level for that pollutant is the final 
deteriorated test result in the sequence determined from table 1 of 
appendix XII of these regulations.
    (2) A manufacturer that elects to conduct a PCA for a pollutant 
using the fixed reduced PCA sampling plan shall:
    (i) Select a sample size between 3 and 23 engines or vehicles. If 
the PCA follows an SEA failure, the sample size selected cannot be less 
than the number of engines or vehicles tested during the SEA; and
    (ii) Conduct emission tests on the selected sample in accordance 
with Sec.86.1111-87 for the pollutants for which the PCA was 
initiated.
    (iii) The compliance level for the pollutant is the result of the 
following equation, using the test results obtained in paragraph 
(a)(2)(ii) of this section and all SEA test results for that pollutant 
if the PCA follows an SEA failure:

CL = X + Ks

Where:

CL = The compliance level.
X= The mean of the final deteriorated test results, as defined by 
          paragraph (e) of this section.
K = A value that depends on the size of the test sample. See table 2 of 
          appendix XII of this part for the value of K that corresponds 
          to the size of the test sample.
s = The sample standard deviation.
Round the compliance level to the same number of significant figures 
          contained in the applicable standard.

    (3) A manufacturer that elects to conduct a PCA for a pollutant 
using the sequential reduced PCA sampling plan shall perform the 
following:
    (i) Select a sample size of 4, 8, 12, 16 or 20 engines or vehicles. 
If the PCA follows an SEA failure, the sample size selected cannot be 
less than the number of engines or vehicles tested during the SEA.
    (ii) Conduct emission tests on the selected sample in accordance 
with Sec.86.1111-87 for the pollutants for which the PCA was 
initiated.
    (iii) The compliance level for the pollutant is the result of the 
following equation, using the test results obtained in (a)(3)(ii) and 
all SEA test results for that pollutant if the PCA follows an SEA 
failure:

CL = X + Ks

Where:

CL = The compliance level.
X = The mean of the final deteriorated test results, as defined by 
          paragraph (e) of this section.
K = A value that depends on the size of the test sample. See table 3 of 
          appendix XII of this part for the value of K that corresponds 
          to the size of the test sample.
s = The sample standard deviation.
    Round the compliance level to the same number of significant figures 
contained in the applicable standard.

    (iv) After calculating a compliance level in accordance with 
paragraph (a)(3)(iii) of this section, a manufacturer may elect to 
increase the sample size by 4 engines or vehicles, or a multiple 
thereof, up to the maximum, including SEA engines or vehicles if any, of 
20. Upon that election, the manufacturer shall add the additional 
engines

[[Page 859]]

or vehicles to the sample and perform paragraphs (a)(3)(ii) and 
(a)(3)(iii) of this section. This election may be repeated if 
appropriate. A compliance level determined under this election shall 
replace a previously determined compliance level.
    (b) A fail decision is reached with respect to the upper limit when 
the compliance level determined in paragraph (a) of this section exceeds 
the applicable upper limit.
    (c) Initial test results are calculated following the Federal Test 
Procedure specified in Sec.86.1111-87(a).
    (d) Final test results are calculated by summing the initial test 
results derived in paragraph (c) of this section for each test engine or 
vehicle, dividing by the number of tests conducted on the engine or 
vehicle, and rounding to the same number of decimal places contained in 
the applicable standard expressed to one additional significant figure.
    (e) Final deteriorated test results. (1) The final deteriorated test 
results for each heavy-duty engine or light-duty truck tested according 
to subpart B, I, N, or P of this part are calculated by applying the 
final test results by the appropriate deterioration factor, derived from 
the certification process for the engine family control system 
combination and model year for the selected configuration to which the 
test engine or vehicle belongs. If the deterioration factor computed 
during the certification process is multiplicative and it is less than 
one, that deterioration factor will be one. If the deterioration factor 
computed during the certification process is additive and it is less 
than zero, that deterioration factor will be zero.
    (2) Round the final deteriorated test results to the same number of 
significant figures contained in the applicable standard.
    (f) A failed engine or vehicle is one whose final deteriorated test 
results, for one or more of the applicable exhaust pollutants, exceed:
    (1) The applicable emission standard, or
    (2) The compliance level established in paragraph (b) of this 
section.
    (g) Within five working days after completion of PCA testing of all 
engines or vehicles, the manufacturer shall submit to the Administrator 
a report which includes the following information:
    (1) The location and description of the manufacturer's emission test 
facilities which were utilized to conduct testing reported pursuant to 
this section;
    (2) The applicable standards against which the engines or vehicles 
were tested;
    (3) Deterioration factors for the engine family to which the 
selected configuration belongs;
    (4) A description of the engine or vehicle and any emission-related 
component selection method used;
    (5) For each test conducted:
    (i) Test engine or vehicle description, including;
    (A) Configuration and engine family identification,
    (B) Year, make and build date,
    (C) Engine or vehicle identification number, and
    (D) Number of hours of service accumulated on engine or number of 
miles on vehicle prior to testing;
    (ii) Location where service or mileage accumulation was conducted 
and description of accumulation procedure and schedule;
    (iii) Test number, date, initial test results before and after 
rounding, final test results and final deteriorated test results for all 
emission tests, whether valid or invalid, and the reason for 
invalidation, if applicable;
    (iv) A complete description of any modification, repair, 
preparation, maintenance, and/or testing which was performed on the test 
engine or vehicle and has not been reported pursuant to any other 
paragraph of this subpart and will not be performed on all other 
production engines or vehicles; and
    (v) Any other information the Administrator may request relevant to 
the determination as to whether the new heavy-duty engines or heavy-duty 
vehicles being manufactured by the manufacturer do in fact conform with 
the regulations of this subpart; and
    (6) The following statement and endorsement:

    This report is submitted pursuant to section 206 of the Clean Air 
Act. This Production Compliance Audit was conducted in

Sec.86.1113-87  Calculation and payment of penalty.

    (a) The NCP for each engine or vehicle for which a compliance level 
has been determined under Sec.86.1112-87 is calculated according to 
the formula in paragraph (a)(1) or (a)(2) of this section depending on 
the value of the compliance level. Each formula contains an annual 
adjustment factor (AAFi) which is defined in paragraph (a)(3) 
of this section. Other terms in the formulas are defined in paragraph 
(a)(4) of this section.
    (1) If the compliance level (CL) is greater than the standard and 
less than or equal to X (e.g., point CL1 in figure 1), then:
[GRAPHIC] [TIFF OMITTED] TR06OC93.111

where:

PR1 = (F) (MC50)

    (2) If the compliance level is greater than X and less than or equal 
to the upper limit as determined by Sec.86.1104-87 (e.g., point 
CL2 in figure 1), then:
[GRAPHIC] [TIFF OMITTED] TR06OC93.112

where:
[GRAPHIC] [TIFF OMITTED] TR06OC93.113

    (3) AAFi has the following values:
    (i) If fraci-1 = 0, then AAFi = 1 + 
Ii-1
    (ii) If fraci-1 0, then:
    [GRAPHIC] [TIFF OMITTED] TR06OC93.114
    

[[Page 861]]


[GRAPHIC] [TIFF OMITTED] TR06OC93.183


If fraci-1 0.50, then fraci-1 will be 
set equal to 0.50.
    (iii) AAF1 = 1
    (iv) In calculating the NCP for year n, the value fraci-1 
for i = n will include actual NCP usage through March 31 of model year 
n-1 and EPA's estimate of additional usage for the remainder of model 
year n-1 using manufacturer input. All manufacturers using NCPs must 
report by subclass actual NCP and non-NCP production numbers through 
March 31, an estimate of NCP and non-NCP production for the remainder of 
the model year, and the previous year's actual NCP and non-NCP 
production to EPA no later than April 30 of the model year. If EPA is 
unable to obtain similar information from manufacturers not using NCPs, 
EPA will use projected sales data from the manufacturers' application 
for certification in computing the total production of the subclass and 
the fraci-1. The value of fraci-1 will be 
corrected to reflect actual year-end usage of NCPs and a corrected AAF 
will be used to establish NCPs in future years. The correction of 
previous year's AAF will not affect the previous year's penalty.
    (4) The terms in the above formulas have the following meanings and 
values, which may be determined separately for each subclass and 
pollutant for which an NCP is offered. The production of Federal and 
California designated engines or vehicles shall be combined for the 
purpose of this section in calculating the NCP for each engine or 
vehicle.

NCPn = NCP for year n for each applicable engine or vehicle
CL = Compliance level for year n for applicable engines or vehicles
S = Emission standard
UL = Upper limit as determined by section 86.1104-87, except that, if 
          the upper limit is determined by section 86.1104-87(c), the 
          value of UL in paragraph (a)(2) of this section shall be the 
          prior emission standard for that pollutant.
UL' = Upper limit as determined by section 86.1104-87(c). This value is 
          not used in the above formulas.
X = Compliance level above the standard at which NCP1 equals 
          COC50

[[Page 862]]

[GRAPHIC] [TIFF OMITTED] TR06OC93.115

PR1 = Penalty rate when CL <=X
PR2 = Penalty rate when X 50 = Estimate of the average total incremental cost to 
          comply with the standard relative to complying with the upper 
          limit.
COC90 = Estimate of the 90th percentile total incremental 
          cost to comply with the standard relative to complying with 
          the upper limit.
MC50 = Estimate of the average marginal cost of compliance 
          (dollars per emission unit) with the standard.
F = Factor used to estimate the 90th percentile marginal cost based on 
          the average marginal cost (the minimum value of F is 1.1, the 
          maximum value of F is 1.3).
AAFi = Annual adjustment factor for year i, 
          fraci-1 = Fraction of engines or vehicles of a 
          subclass using NCPs in previous year (year i-1).
Ai = Usage adjustment factor in year i: Ai = 0.10 
          for i = 2; Ai = 0.08 for i<2.
Ii = Percentage increase in overall consumer price index in 
          year i.

    (5) The values of COC50, COC90, 
MC50 and F will be determined for each applicable subclass by 
EPA based on the cost data used by EPA in setting the applicable 
emission standard. However, where the rulemaking to establish a specific 
NCP occurs after the rulemaking to establish the standard, EPA may 
augment the data base used to establish the standard by including the 
best cost and emission performance data available to EPA during the 
specific NCP rulemaking.
    (6) In calculating the NCP, appropriate values of the following 
predefined terms should be used: CL, S, UL, F, and Ai. For 
all other terms, unrounded values of at least five figures beyond the 
decimal point should be used in calculations leading up to the penalty 
amount. Any NCP calculated under paragraph (a) of this section will be 
rounded to the nearest dollar.
    (b) The NCP determined in paragraph (a) of this section is assessed 
against all those engines or vehicles of the nonconforming configuration 
or engine family produced at all assembly plants and distributed into 
commerce--
    (1) Since the beginning of the model year in the case of a 
certification failure described by Sec.86.1106-87(a).
    (2) Beginning ten days after an SEA failure described by Sec.
86.1106-87 (b) or (c).
    (3) Following implementation of a production running change 
described by Sec.86.1106-87(d).
    (c) The NCP will continue to be assessed during the model year, 
until such time, if any, that the configuration or engine family is 
brought into conformance with applicable emission standards.
    (d) A manufacturer may carry over an NCP from a model year to the 
next model year. There is no limit to the number of years that carryover 
can continue. The amount of the penalty will increase each year 
according to paragraph (a) of this section.
    (e) The Administrator shall notify the manufacturer in writing of 
the nonconformance penalty established under paragraph (a) of this 
section after the completion of the PCA under Sec.86.1112-87.

[[Page 863]]

    (f) A manufacturer may request a hearing under 40 CFR part 1068, 
subpart G, as to whether the compliance level (including a compliance 
level in excess of the upper limit) was determined properly.
    (g)(1) Except as provided in paragraph (g)(2) of this section, the 
nonconformance penalty or penalties assessed under this subpart must be 
paid as follows:
    (i) By the quarterly due dates, i.e., within 30 days of the end of 
each calendar quarter (March 31, June 30, September 30 and December 31), 
or according to such other payment schedule as the Administrator may 
approve pursuant to a manufacturer's request, for all nonconforming 
engines or vehicles produced by a manufacturer in accordance with 
paragraph (b) of this section and distributed into commerce for that 
quarter.
    (ii) The penalty shall be payable to U.S. Environmental Protection 
Agency, NCP Fund, Motor Vehicle and Engine Compliance Program, P.O. Box 
979032 St. Louis, MO 63197-9000. Note on the check and supporting 
information that this is an NCP payment.
    (2) When a manufacturer has requested a hearing under Sec.86.1115-
87, it must pay the nonconformance penalty, and any interest, within ten 
days after the Presiding Officer renders his decision, unless the 
manufacturer first files a notice of intention to appeal to the 
Administrator pursuant to Sec.86.1115-87(t)(1), or, if an appeal of 
the Presiding Officer's decision is taken, within ten days after the 
Administrator renders his decision, unless the manufacturer first files 
a petition for judicial review.
    (3) A manufacturer making payment under paragraph (g)(1) or (2) of 
this section shall submit the following information by each quarterly 
due date to the Designated Compliance Officer (see 40 CFR 1036.801). 
This information shall be submitted even if a manufacturer has no NCP 
production in a given quarter.
    (i) Corporate identification, identification and quantity of engines 
or vehicles subject to the NCP, certificate identification (number and 
date), NCP payment calculations and interest payment calculations, if 
applicable.
    (ii) The following statement and endorsement:

    This information is submitted pursuant to section 206 of the Clean 
Air Act. All information reported herein is, to the best of
_____________________'s
(Company name)

knowledge, true and accurate. I am aware of the penalties associated 
with violations of the Clean Air Act and the regulations thereunder.

________________________________________________________________________
(Authorized Company Representative)

    (4) The Administrator may verify the production figures or other 
documentation submitted under paragraph (g)(3) of this section.
    (5)(i) Interest shall be assessed on any nonconformance penalty for 
which payment has been withheld under Sec.86.113-87(g) (1) or (2). 
Interest shall be calculated from the due date for the first quarterly 
NCP payment, as determined under Sec.86.1113-87(g)(1), until either 
the date on which the Presiding Officer or the Administrator renders the 
final decision of the Agency under Sec.86.1115-87 or the date when an 
alternate payment schedule (approved pursuant to Sec.86.1113-87(g)(1)) 
ends.
    (ii) The combined principal plus interest on each quarterly NCP 
payment withheld pursuant to Sec.86.1113-87(g) (1) or (2) shall be 
calculated according to the formula:

QNCP(1 + R).25n

where:
QNCP = the quarterly NCP payment
R = the interest rate applicable to that quarter
n = the number of quarters for which the quarterly NCP payment is 
          outstanding.

    (iii) The number of quarters for which payment is outstanding for 
purposes of this paragraph shall be the number of quarterly NCP payment 
due dates, as determined under Sec.86.1113-87(g)(1), which have 
elapsed throughout the duration of a hearing request, or alternate 
payment schedule.
    (iv) The interest rate applicable to a quarter for purposes of this 
paragraph shall be the rate published by the Secretary of the Treasury 
pursuant to the Debt Collection Act of 1982 and effective on the date on 
which the NCP payment was originally due.

[[Page 864]]

    (6) A manufacturer will be refunded an overpayment, or be permitted 
to offset an overpayment by withholding a future payment, if approved in 
advance by the Administrator. The government shall pay no interest on 
overpayments.
    (h) A manufacturer that certifies as a replacement for the 
nonconforming configuration, a configuration that is in conformance with 
applicable standards, and that performs a production compliance audit 
(PCA) in accordance with Sec.86.1112-87(a) that results in a 
compliance level below the applicable standard, will be eligible to 
receive a refund of a portion of the engineering and development 
component of the penalty. The engineering and development component will 
be determined by multiplying the base penalty amount by the engineering 
and development factor for the appropriate subclass and pollutant in 
Sec.86.1105-87. The amount refunded will depend on the model year in 
which the certification and PCA take place. In cases where payment of 
penalties have been waived by EPA in accordance with paragraph 
(g)(1)(iii) of this section, EPA will refund a portion of the 
engineering and development component. The proportionate refund to be 
paid by EPA will be based on the proportion of vehicles or engines of 
the nonconforming configuration for which NCPs were paid to EPA. The 
refund is calculated as follows:

Rtot = Dn x FE&D x NCP1 x 
Prodtot

RCal = (ProdCal/Prodtot) x 
(Rtot)

REPA = Rtot-RCal

Where:

n = index representing the number of model years for which the NCP has 
          been available for an engine or vehicle subclass (i.e., n = 1 
          for the first year that NCPs are available, . . . , n = n for 
          the n\th\ year the NCPs are available; same as ``n'' in 
          paragraph (a)(4)).
Dn = discount factor depending on the number of model years 
          (n) for which NCPs were available at the time of certification 
          and PCA of the replacement configuration, and its value is as 
          follows:
    D1 = 0.90
    D2 = 0.79
    D3 = 0.67
    D4 = 0.54
    D5 = 0.39
    D6 = 0.23
    D7 = 0.05
    Dn = 0.00 for n = 8 or larger
FE&D = the engineering and development factor specified in 
          section 86.1105-87 for the appropriate subclass and pollutant
NCP1 = the penalty for each engine or vehicle during the 
          first (base) year the NCP is available as calculated in 
          paragraph (a)
Prodtot = total number of engines or vehicles produced in the 
          subclass for which NCPs were paid to EPA or to the State of 
          California
ProdCal = number of engines or vehicles in the subclass 
          demonstrated to have been titled, registered or principally 
          used in the State of California and for which NCPs were paid 
          to the State of California under paragraph (g)(1)
Rtot = Total refund due to the manufacturer for the 
          engineering and development component of the NCP
RCal = Refund due to the manufacturer from the State of 
          California for the engineering and development component of 
          the NCP
REPA = Refund due to the manufacturer from EPA for the 
          engineering and development component of the NCP.

Sec.86.1305  Introduction; structure of subpart.

    (a) This subpart specifies the equipment and procedures for 
performing exhaust-emission tests on Otto-cycle and diesel-cycle heavy-
duty engines. Subpart A of this part sets forth the emission standards 
and general testing requirements to comply with EPA certification 
procedures.
    (b) Use the applicable equipment and procedures for spark-ignition 
or compression-ignition engines in 40 CFR part 1065 to determine whether 
engines meet the duty-cycle emission standards in subpart A of this 
part. Measure the emissions of all regulated pollutants as specified in 
40 CFR part 1065. Use the duty cycles and procedures specified in 
Sec. Sec.86.1333, 86.1360, and 86.1362. Adjust emission results from 
engines using aftertreatment technology with infrequent regeneration 
events as described in Sec.86.004-28.
    (c) The provisions in Sec. Sec.86.1370 and 86.1372 apply for 
determining whether an engine meets the applicable not-to-exceed 
emission standards.
    (d) Measure smoke using the procedures in subpart I of this part for 
evaluating whether engines meet the smoke standards in subpart A of this 
part.
    (e) Use the fuels specified in 40 CFR part 1065 to perform valid 
tests, as follows:
    (1) For service accumulation, use the test fuel or any commercially 
available fuel that is representative of the fuel that in-use engines 
will use.
    (2) For diesel-fueled engines, use the ultra low-sulfur diesel fuel 
specified in 40 CFR part 1065 for emission testing.
    (3) For gasoline-fueled engines, use the appropriate E10 fuel 
specified in 40 CFR part 1065; however, through model year 2021 you may 
instead use the appropriate E0 fuel specified in 40 CFR part 1065, with 
the exception that the E0 fuel must have sulfur concentration between 
0.0015 and 0.008 weight percent and research octane of at least 93. 
Starting in model year 2022, you may certify up to 5 percent of your 
nationwide sales volume of engines certified under subpart A of this 
part in a given model year based on this E0 test fuel if those engines 
are certified with carryover data.
    (f) You may use special or alternate procedures to the extent we 
allow them under 40 CFR 1065.10. In addition, for 2010 and earlier model 
year engines, you may use modified test procedures as needed to conform 
to the procedures

[[Page 867]]

that were specified at the time of emission testing for the model year 
in question.
    (g) This subpart applies to you as a manufacturer, and to anyone who 
does testing for you.
    (h) For testing conducted with engines installed in vehicles, 
including field testing conducted to measure emissions under Not-To-
Exceed test procedures, use the test procedures and equipment specified 
in 40 CFR part 1065, subpart J.
    (i) You may disable any AECDs that have been approved solely for 
emergency vehicle applications under paragraph (4) of the definition of 
``Defeat device'' in Sec.86.004-2. The emission standards do not apply 
when any of these AECDs are active.

Sec.86.1333  Transient test cycle generation.

    (a) Generating transient test cycles. The heavy-duty transient 
engine cycles for Otto-cycle and diesel engines are listed in appendix 
I((f) (1), (2) and (3)) to this part. These second-by-second listings 
represent torque and rpm maneuvers characteristic of heavy-duty engines. 
Both rpm and torque are normalized (expressed as a percentage of 
maximum) in these listings.
    (1) To unnormalize rpm, use the following equations:
    (i) For diesel engines:
    [GRAPHIC] [TIFF OMITTED] TR28AP14.006
    
Where:

Max Test Speed = the maximum test speed as calculated in 40 CFR part 
          1065.

    (ii) For Otto-cycle engines:
    [GRAPHIC] [TIFF OMITTED] TR28AP14.007
    
Where:

Max Test Speed = the maximum test speed as calculated in 40 CFR part 
          1065.

    (2) Torque is normalized to the maximum torque at the rpm listed 
with it. Therefore, to unnormalize the torque values in the cycle, the 
maximum torque curve for the engine in question must be used. The 
generation of the maximum torque curve is described in 40 CFR part 1065.
    (b) Example of the unnormalization procedure. Unnormalize the 
following test point, given Maximum Test speed = 3800 rpm and Curb Idle 
Speed = 600 rpm.
[GRAPHIC] [TIFF OMITTED] TR13JY05.003

    (1) Calculate actual rpm:
    [GRAPHIC] [TIFF OMITTED] TR13JY05.004
    
    (2) Determine actual torque: Determine the maximum observed torque 
at 1829 rpm from the maximum torque curve. Then multiply this value 
(e.g., 358 ft-lbs) by 0.82. This results in an actual torque of 294 ft-
lbs.
    (c) Clutch operation. Manual transmission engines may be tested with 
a

[[Page 868]]

clutch. If used, the clutch shall be disengaged at all zero percent 
speeds, zero percent torque points, but may be engaged up to two points 
preceding a non-zero point, and may be engaged for time segments with 
zero percent speed and torque points of durations less than four 
seconds.
    (d) Determine idle speeds as specified in 40 CFR 1065.510.

Sec.86.1360  Supplemental emission test; test cycle and procedures.

    The test procedures of this subpart N apply for supplemental 
emission testing, except as specified otherwise in this section.
    (a) Applicability. This section applies to 2007 and later diesel 
heavy duty engines.
    (b) Test cycle. (1) Perform testing as described in Sec.86.1362 
for determining whether an engine meets the applicable standards when 
measured over the supplemental emission test.
    (2) For engines not certified to a NOX standard or FEL 
less than 1.5 g/bhp-hr, EPA may select, and require the manufacturer to 
conduct the test using, up to three discrete test points within the 
control area defined in paragraph (d) of this section. EPA will notify 
the manufacturer of these supplemental test points in writing in a 
timely manner before the test. Emission sampling for these discrete test 
modes must include all regulated pollutants except particulate matter.
    (3) For engines certified using the ramped-modal cycle specified in 
Sec.86.1362, perform the three discrete test points described in 
paragraph (b)(2) of this section as follows:
    (i) Allow the engine to idle as needed to complete equipment checks 
following the supplemental emission test described in this section, then 
operate the engine over the three additional discrete test points.
    (ii) Validate the additional discrete test points as a composite 
test separate from the supplemental emission test, but in the same 
manner.
    (iii) Use the emission data collected during the time interval from 
35 to 5 seconds before the end of each mode (excluding transitions) to 
perform the MAEL calculations in paragraph (f) of this section.
    (c) The engine speeds A, B and C, referenced in the table in 
paragraph (b)(1) of this section, must be determined as follows:

Speed A = nlo + 0.25 x (nhi - nlo)
Speed B = nlo + 0.50 x (nhi - nlo)
Speed C = nlo + 0.75 x (nhi - nlo)

Where: nhi = High speed as determined by calculating 70% of 
          the maximum power. The highest engine speed where this power 
          value occurs on the power curve is defined as nhi.
nlo = Low speed as determined by calculating 50% of the 
          maximum power. The lowest engine speed where this power value 
          occurs on the power curve is defined as nlo.
Maximum power = the maximum observed power calculated according to the 
          engine mapping procedures defined in 40 CFR 1065.510.

    (d) Determining the control area. The control area extends from the 
engine speed A to C, as defined in paragraph (c) of this section, and 
extends from 25 to 100 percent load.
    (e) [Reserved]
    (f) Maximum allowable emission limits. (1) For gaseous emissions, 
the 12 non-idle test point results and the four-point linear 
interpolation procedure specified in paragraph (g) of this section for 
intermediate conditions, shall define Maximum Allowable Emission Limits 
for purposes of Sec.86.007-11(a)(3) except as modified under paragraph 
(f)(3) of this section. Each engine shall have it's own Maximum 
Allowable Emission Limits generated from the 12 non-idle supplemental 
steady state test points from that engine. The control area extends from 
the 25% to the 75% engine speeds, at engine loads of 25% to 100%, as 
defined in paragraph (d) of this section. Figure 1 of this paragraph 
(f)(1) depicts a sample Maximum Allowable Emission Limit curve, for 
illustration purposes only, as follows:

[[Page 869]]

[GRAPHIC] [TIFF OMITTED] TR06OC00.006

    (2) If the weighted average emissions, calculated according to 
paragraph (e)(6) of this section, for any gaseous pollutant is equal to 
or lower than required by Sec.86.007-11(a)(3), each of the 13 test 
values for that pollutant shall first be multiplied by the ratio of the 
applicable emission standard (under Sec.86.007-11(a)(3)) to the 
weighted average emissions value, and then by 1.10 for interpolation 
allowance, before determining the Maximum Allowable Emission Limits 
under paragraph (f)(1) of this section.
    (3) If the Maximum Allowable Emission Limit for any point, as 
calculated under paragraphs (f)(1) and (2) of this section, is greater 
than the applicable Not-to-Exceed limit (if within the Not-to-Exceed 
control area defined in Sec.86.1370(b)), then the Maximum Allowable 
Emission Limit for that point shall be defined as the applicable Not-to-
Exceed limit.
    (g) Calculating intermediate test points. (1) For the three test 
points selected by EPA under paragraph (b)(2) of this section, the 
emissions must be measured and calculated as described in paragraph 
(e)(6)(i) of this section (except that n = 1 and WF = 1). The measured 
values then must be compared to the interpolated values according to 
paragraph (g)(3) of this section. The interpolated values are determined 
from the modes of the test cycle closest to the respective test point 
according to paragraph (g)(2) of this section.
    (2) Interpolating emission values from the test cycle. The gaseous 
emissions for each regulated pollutant for each of the control points 
(Z) must be interpolated from the four closest modes of the test cycle 
that envelop

[[Page 870]]

the selected control point Z as shown in Figure 2 of this paragraph 
(g)(2).
    (i) For these modes (R, S, T, U), the following definitions apply:
    (A) Speed (R) = Speed(T) = nRT.
    (B) Speed (S) = Speed(U) = nSU.
    (C) Per cent load (R) = Per cent load (S).
    (D) Per cent load (T) = Per cent load (U).
    (ii) The interpolated value of the brake specific gaseous emissions 
of the selected control point Z(EZ) must be calculated as follows:

EZ = ERS + (ETU-ERS) * 
(MZ-MRS) / (MTU-MRS)

ETU = ET + (EU-ET) * 
(nZ-nRT) / (nSU-nRT)

ERS = ER + (ES-ER) * 
(nZ-nRT) / (nSU-nRT)

MTU = MT + (MU-MT) * 
(nZ-nRT) / (nSU-nRT)

MRS = MR + (MS-MR) * 
(nZ-nRT) / (nSU-nRT)

Where:

ER, ES, ET, EU = for each 
          regulated pollutant, brake specific gaseous emissions of the 
          enveloping modes adjusted according to the factors in(f)(2).
MR, MS, MT, MU = engine 
          torque of the enveloping modes.
MZ = engine torque of the selected control point Z.
nZ = engine speed of the selected control point Z.

    (iii) Figure 2 follows:
    [GRAPHIC] [TIFF OMITTED] TR06OC00.007
    
    (3) Comparing calculated and interpolated emission values. The 
measured brake specific gaseous emissions of the control point Z 
(XZ) must be less than or equal to the interpolated value 
(EZ).

Sec.86.1370  Not-To-Exceed test procedures.

    (a) General. The purpose of this test procedure is to measure in-use 
emissions of heavy-duty diesel engines while operating within a broad 
range of speed and load points (the Not-To-Exceed Control Area) and 
under conditions which can reasonably be expected to be encountered in 
normal vehicle operation and use. Emission results from this test 
procedure are to be compared to the Not-To-Exceed Limits specified in 
Sec.86.007-11(a)(4), or to later Not-To-Exceed Limits. The Not-To-
Exceed Limits do not apply for engine-starting conditions. Tests 
conducted using the procedures specified in this subpart are considered 
valid Not-To-Exceed tests (Note: duty cycles and limits on ambient 
conditions do not apply for Not-To-Exceed tests).
    (b) Not-to-exceed control area for diesel heavy-duty engines. The 
Not-To-Exceed Control Area for diesel heavy-duty engines consists of the 
following engine speed and load points:
    (1) All operating speeds greater than the speed calculated using the 
following formula, where nhi and nlo are 
determined according to the provisions in Sec.86.1360(c):

nlo + 0.15 x (nhi-nlo)

    (2) All engine load points greater than or equal to 30% or more of 
the maximum torque value produced by the engine.
    (3) Notwithstanding the provisions of paragraphs (b)(1) and (2) of 
this section, all operating speed and load points with brake specific 
fuel consumption (BSFC) values within 5% of the minimum BSFC value of 
the engine. For the purposes of this requirement, BFSC must be 
calculated under the general test cell conditions specified in 40 CFR 
part 1065. The manufacturer may petition the Administrator at 
certification to exclude such points if the manufacturer can demonstrate 
that the engine is not expected to operate at such points in normal 
vehicle operation and use. Engines equipped with drivelines with multi-
speed manual transmissions or automatic transmissions with a finite 
number of gears are not subject to the requirements of this paragraph 
(b)(3).
    (4) Notwithstanding the provisions of paragraphs (b)(1) through 
(b)(3) of this section, speed and load points below 30% of the maximum 
power value produced by the engine shall be excluded from the Not-To-
Exceed Control Area for all emissions.
    (5) [Reserved]
    (6)(i) For petroleum-fueled diesel cycle engines, the manufacturer 
may identify particular engine-vehicle combinations and may petition the 
Administrator at certification to exclude operating points from the Not-
to-Exceed Control Area defined in paragraphs (b)(1) through (5) of this 
section if the manufacturer can demonstrate that the engine is not 
capable of operating at such points when used in the specified engine-
vehicle combination(s).
    (ii) For diesel cycle engines that are not petroleum-fueled, the 
manufacturer may petition the Administrator at certification to exclude 
operating points from the Not-to-Exceed Control Area defined in 
paragraphs (b)(1)

[[Page 873]]

through (5) of this section if the manufacturer can demonstrate that the 
engine is not expected to operate at such points in normal vehicle 
operation and use.
    (7) Manufacturers may petition the Administrator to limit NTE 
testing in a single defined region of speeds and loads. Such a defined 
region must generally be of elliptical or rectangular shape, and must 
share some portion of its boundary with the outside limits of the NTE 
zone. Under this provision testing would not be allowed with sampling 
periods in which operation within that region constitutes more than 5.0 
percent of the time-weighted operation within the sampling period. 
Approval of this limit by the Administrator is contingent on the 
manufacturer satisfactorily demonstrating that operation at the speeds 
and loads within that region accounts for less than 5.0 percent of all 
in-use operation (weighted by vehicle-miles-traveled or other EPA-
approved weightings) for the in-use engines of that configuration (or 
sufficiently similar engines). At a minimum, this demonstration must 
include operational data from representative in-use vehicles.
    (c) [Reserved]
    (d) Not-to-exceed control area limits. (1) When operated within the 
Not-To-Exceed Control Area defined in paragraph (b) of this section, 
diesel engine emissions shall not exceed the applicable Not-To-Exceed 
Limits specified in Sec.86.007-11(a)(4) when averaged over any time 
period greater than or equal to 30 seconds, except where a longer 
minimum averaging period is required by paragraph (d)(2) of this 
section.
    (2) For engines equipped with emission controls that include 
discrete regeneration events and that send a recordable electronic 
signal indicating the start and end of the regeneration event, determine 
the minimum averaging period for each NTE event that includes 
regeneration active operation as described in paragraph (d)(2)(i) of 
this section. This minimum averaging period is used to determine whether 
the individual NTE event is a valid NTE event. For engines equipped with 
emission controls that include multiple discrete regeneration events 
(e.g., de-soot, de-NOX, de-SOX, etc.) and 
associated electronic signals, if an NTE event includes regeneration 
active operation on multiple regeneration signals, determine the minimum 
averaging period for each regeneration signal according to paragraph 
(d)(2)(i) of this section and use the longest period. This minimum 
averaging period applies if it is longer than 30 seconds. The electronic 
signal from the engine's ECU must indicate non-regeneration and 
regeneration operation. Regeneration operation may be further divided 
into regeneration pending and regeneration active operation. These are 
referred to as states 0, 1, and 2 for non-regeneration, regeneration 
pending, and regeneration active operation, respectively. No further 
subdivision of these states are allowed for use in this paragraph 
(d)(2). Where the electronic signal does not differentiate between 
regeneration pending and active operation, take the regeneration signal 
to mean regeneration active operation (state 2). A complete non-
regeneration event is a time period that occurs during the course of the 
shift-day that is bracketed by regeneration operation, which is either 
regeneration active operation (state 2) or regeneration pending 
operation (state 1). A complete regeneration event is a time period that 
occurs during the course of the shift-day that is bracketed before and 
after by non-regeneration operation (state 0); a complete regeneration 
event includes any time in the event where regeneration is pending 
(state 1). The following figure provides an example of regeneration 
events during a shift-day:

[[Page 874]]

[GRAPHIC] [TIFF OMITTED] TR08NO10.021

    (i) Calculate the minimum averaging period, tNTE,min, for 
each candidate NTE event as follows:

[[Page 875]]

[GRAPHIC] [TIFF OMITTED] TR08NO10.023

Where:
i = an indexing variable that represents periods of time within the 
          candidate NTE event where the electronic signal indicates 
          regeneration active operation (state 2).
N = the number of periods of time within the candidate NTE event where 
          the electronic signal indicates regeneration active operation 
          (state 2).
t2,NTE,i = the duration of the i-th time period within the 
          candidate NTE event where the electronic signal indicates 
          regeneration active operation (state 2), in seconds.
RF = regeneration fraction over the course of the shift-day, as 
          determined in paragraph (d)(2)(ii) of this section.

    (ii) Calculate the regeneration fraction, RF, over the course of a 
shift-day as follows:
[GRAPHIC] [TIFF OMITTED] TR08NO10.024

Where:
i = an indexing variable that represents complete regeneration events 
          within the shift-day.
j = an indexing variable that represents periods of time within the i-th 
          complete regeneration event where the electronic signal 
          indicates regeneration active operation (state 2).
k = an indexing variable that represents complete non-regeneration 
          events within the shift-day.
N0 = the number of complete non-regeneration events within 
          the shift-day.
N12 = the number of complete regeneration events within the 
          shift-day.
N2,i = the number of periods of within the i-th complete 
          regeneration event where the electronic signal indicates 
          regeneration active operation (state 2).
t0,k = the duration of the k-th complete non-regeneration 
          event within the shift-day, in seconds.
t12,i = the duration of the i-th complete regeneration event 
          within the shift-day, in seconds, including time in those 
          events where regeneration is pending (state 1).
t2,i,j = the duration of the j-th time period within the i-th 
          complete regeneration event where the electronic signal 
          indicates regeneration active operation (state 2), in seconds. 
          Note that this excludes time in each complete regeneration 
          event where regeneration is pending (state 1).

    (iii) If either N0 or N12 are zero, then RF 
cannot be calculated and all candidate NTE events that include 
regeneration active operation are void.
    (iv) Compare the minimum averaging period for the candidate NTE 
event, tNTE,min, to the actual NTE duration, tNTE. 
If tNTE NTE,min the candidate NTE event is void. 
If tNTE =tNTE,min the candidate NTE 
event is valid. It can also therefore be included in the overall 
determination of vehicle-pass ratio according to Sec.86.1912.
    (v) You may choose to not void emission results for a candidate NTE 
event even though we allow you to void the NTE event under paragraph 
(d)(2)(iii) or (iv) of this section. If you choose this option, you must 
include the results for all regulated pollutants that

[[Page 876]]

were measured and validated during the NTE event for a given NTE 
monitoring system.
    (vi)(A) The following is an example of calculating the minimum 
averaging period, tNTE,min, for a candidate NTE event. See 
Figure 1 of this section for an illustration of the terms to calculate 
the regeneration fraction, RF. For this example there are three complete 
non-regeneration events and two complete regeneration events in the 
shift-day.

N0 = 3
N12 = 2

    (B) The duration of the three complete non-regeneration events 
within the shift-day are:

t0,1 = 5424 s
t0,2 = 6676 s
t0,3 = 3079 s

    (C) The sums of all the regeneration active periods in the two 
complete regeneration events are:
[GRAPHIC] [TIFF OMITTED] TR08NO10.025

    (D) The duration of each of the two complete regeneration events 
within the shift-day are:

t12,1 = 8440 s
t12,2 = 3920 s


    (E) The RF for this shift-day is:
    [GRAPHIC] [TIFF OMITTED] TR08NO10.026
    
    (F) For this example, consider a candidate NTE event where there are 
two periods of regeneration active operation (state 2).

t2,NTE,1 = 37 s
t2,NTE,2 = 40 s

    (G) The minimum averaging period for this candidate NTE event is:
    [GRAPHIC] [TIFF OMITTED] TR08NO10.027
    
tNTE,min = 320.0 s
    (e) Ambient corrections. The measured data shall be corrected based 
on the ambient conditions under which it was taken, as specified in this 
section.
    (1) For engines operating within the ambient conditions specified in 
Sec.86.007-11(a)(4)(ii)(a):
    (i) NOX emissions shall be corrected for ambient air 
humidity to a standard humidity level of 50 grains (7.14 g/kg) if the 
humidity of the intake air was

[[Page 877]]

below 50 grains, or to 75 grains (10.71 g/kg) if above 75 grains.
    (ii) NOX and PM emissions shall be corrected for ambient 
air temperature to a temperature of 55 degrees F (12.8 degrees C) for 
ambient air temperatures below 55 degrees F or to 95 degrees F (35.0 
degrees C) if the ambient air temperature is above 95 degrees F.
    (iii) No ambient air temperature or humidity correction factors 
shall be used within the ranges of 50-75 grains or 55-95 degrees F.
    (iv) Where test conditions require such correction factors, the 
manufacturer must use good engineering judgement and generally accepted 
engineering practice to determine the appropriate correction factors, 
subject to EPA review.
    (2) For engines operating within the ambient conditions specified in 
Sec.86.007-11(a)(4)(ii)(b):
    (i) NOX emissions shall be corrected for ambient air 
humidity to a standard humidity level of 50 grains (7.14 g/kg) if the 
humidity of the intake air was below 50 grains, or to 75 grains (10.71 
g/kg) if above 75 grains.
    (ii) NOX and PM emissions shall be corrected for ambient 
air temperature to a temperature of 55 degrees F (12.8 degrees C) for 
ambient air temperatures below 55 degrees F.
    (iii) No ambient air temperature or humidity correction factors 
shall be used within the ranges of 50-75 grains or for temperatures 
greater than or equal to 55 degrees F.
    (iv) Where test conditions require such correction factors, the 
manufacturer must use good engineering judgement and generally accepted 
engineering practice to determine the appropriate correction factors, 
subject to EPA review.
    (f) NTE cold temperature operating exclusion. Engines equipped with 
exhaust gas recirculation (EGR) whose operation within the NTE control 
area specified in paragraph (b) of this section when operating during 
cold temperature conditions as specified in paragraph (f)(1) of this 
section are not subject to the NTE emission limits during the specified 
cold temperature conditions.
    (1) Cold temperature operation is defined as engine operating 
conditions meeting either of the following two criteria:
    (i) Intake manifold temperature (IMT) less than or equal to the 
temperature defined by the following relationship between IMT and 
absolute intake manifold pressure (IMP) for the corresponding IMP:
[GRAPHIC] [TIFF OMITTED] TR06OC00.009

Where:

P = absolute intake manifold pressure in bars.
IMT = intake manifold temperature in degrees Fahrenheit.

    (ii) Engine coolant temperature (ECT) less than or equal to the 
temperature defined by the following relationship between ECT and 
absolute intake manifold pressure (IMP) for the corresponding IMP:
[GRAPHIC] [TIFF OMITTED] TR06OC00.010

Where:

P = absolute intake manifold pressure in bars.
ECT = engine coolant temperature in degrees Fahrenheit.

    (2) [Reserved]
    (g) You may exclude emission data based on catalytic aftertreatment 
temperatures as follows:
    (1) For an engine equipped with a catalytic NOX 
aftertreatment system, exclude NOX emission data that is 
collected when the exhaust temperature at any time during the NTE event 
is less than 250 [deg]C.
    (2) For an engine equipped with an oxidizing catalytic 
aftertreatment system, exclude NMHC and CO emission data that is 
collected if the exhaust temperature is less than 250 [deg]C at any time 
during the NTE event.
    (3) Using good engineering judgment, measure exhaust temperature 
within 30 cm downstream of the last applicable catalytic aftertreatment 
device. Where there are parallel paths, use good engineering judgment to 
measure the temperature within 30 cm downstream of the last applicable 
catalytic aftertreatment device in the path with the greatest exhaust 
flow.
    (h) Any emission measurements corresponding to engine operating 
conditions that do not qualify as a valid NTE sampling event may be 
excluded

[[Page 878]]

from the determination of the vehicle-pass ratio specified in Sec.
86.1912 for the specific pollutant.
    (i) Start emission sampling at the beginning of each valid NTE 
sampling event, except as needed to allow for zeroing or conditioning 
the PEMS. For gaseous emissions, PEMS preparation must be complete for 
all analyzers before starting emission sampling.
    (j) Emergency vehicle AECDs. If your engine family includes engines 
with one or more approved AECDs for emergency vehicle applications under 
paragraph (4) of the definition of ``defeat device'' in Sec.86.1803, 
the NTE emission limits do not apply when any of these AECDs are 
active.apply when any of these AECDs are active.

Sec.86.1527  Idle test procedure; overview.

    (a) The idle emission test procedure is designed to determine the 
raw concentration (in percent) of CO in the exhaust flow at idle. The 
test procedure begins with the engine at normal operating temperature. 
(For example, the warm-up for an engine may be the transient engine or 
chassis dynamometer test.)
    (b) Raw emission sampling must be made before dilution occurs from a 
single exhaust pipe in which exhaust products are homogeneously mixed. 
The configuration for dual-exhaust systems must also allow for raw 
emission measurements, which will require that an additional ``Y'' pipe 
be placed in the exhaust system before dilution.

Redesignated at 73 FR 37194, June 30, 2008]



Sec.86.1537  Idle test run.

    The following steps shall be taken for each test:
    (a) Check the device(s) for removing water from the exhaust sample 
and the sample filter(s). Remove any water from the water trap(s). Clean 
and replace the filter(s) as necessary.
    (b) Set the zero and span points of the CO analyzer with the 
electrical spanning network or with analytical gases.
    (c) Achieve normal engine operating condition. The transient engine 
or chassis dynamometer test is an acceptable technique for warm-up to 
normal operating condition for the idle test. If the emission test is 
not performed prior to the idle emission test, a heavy-duty engine may 
be warmed up according to 40 CFR part 1065, subpart F. A light-duty 
truck may be warmed up by operation through one Urban Dynamometer 
Driving Schedule test procedure (see Sec.86.115-78 and appendix I to 
this part).
    (d) Operate the warm engine at 2500 50 rpm, or 
rated torque speed for diesel-cycle engines, and zero load for a minimum 
of 30 seconds and a maximum of 6 minutes.
    (e) If the CVS sampling system is used, the following procedures 
apply:
    (1) If bag samples are drawn, with the sample selector valves in the 
standby position connect evacuated sample collection bags to the dilute 
exhaust and dilution air sample collection systems.
    (2) Start the CVS (if not already on), the sample pumps, 
integrators, and the raw CO2 analyzer, as applicable. (The 
heat exchanger of the constant volume sampler, if used, shall be running 
at operating temperature before sampling begins.)
    (3) Adjust the sample flow rates to the desired flow rate and set 
the gas flow measuring devices to zero.
    (4) Operate the engine or vehicle at curb idle for 305 seconds with the clutch disengaged or in neutral gear. 
A heavy-duty engine may also be disconnected from the dynamometer, or 
the dynamometer may be shut off.
    (5) Begin raw and dilute sampling.
    (6) For bag sampling, sample idle emissions long enough to obtain a 
sufficient bag sample, but in no case shorter than 60 seconds nor longer 
than 6 minutes. Follow the sampling and exhaust measurements 
requirements of 40 CFR part 1065, subpart F, for conducting the raw 
CO2 measurement.
    (7) As soon as possible, transfer the idle test exhaust and dilution 
air samples to the analytical system and process the samples according 
to Sec.86.1540-84. Obtain a stabilized reading of the exhaust sample 
on all analyzers within 20 minutes of the end of the sample collection 
phase of the test.
    (f) If the raw exhaust sampling and analysis technique specified in 
40 CFR part 1065 is used, the following procedures apply:
    (1) Warm up the engine or vehicle per paragraphs (c) and (d) of this 
section. Operate the engine or vehicle at the conditions specified in 
paragraph (e)(4) of this section.
    (2) Follow the sampling and exhaust measurement requirements of 40 
CFR part 1065, subpart F. The idle sample shall be taken for 60 seconds 
minimum, and no more than 64 seconds. The chart reading procedures of 40 
CFR part 1065, subpart F, shall be used to determine the analyzer 
response.
    (g) If the engine or vehicle stalls at any time during the test run, 
the test is void.

CO and CO2 specified in 40 CFR part 1065 apply. Follow the 
raw CO2 analysis procedure specified in 40 CFR part 1065, 
subpart F, for the raw CO2 analyzer.
    (c) If the continuous raw exhaust sampling technique specified in 40 
CFR part 1065 is used, the analysis procedures for CO specified in 40 
CFR part 1065, subpart F, apply.

    (5) Convert the dilute wet-basis CO to dilute dry-basis values. An 
assumption that the percent of water by volume in the sample bag is 2 
percent is acceptable. For example:

Dilute dry CO = (dilute wet CO)/(1.00-0.02)

    (6) Calculate the raw dry-basis CO values by:

Raw dry CO = (DF) (dilute dry CO)

    (c) If the raw exhaust sampling and analysis system specified in 40

FR 59963, Oct. 6, 2000]



Sec.86.1602  Definitions.

    The definitions provided in subpart A also apply in this subpart. 
Additional definitions that apply in this subpart are as follow:
    Altitude performance adjustments are adjustments or modifications 
made to

[[Page 885]]

vehicle, engine, or emission control functions in order to improve 
emission control performance at altitudes other than those for which the 
vehicles were designed.
    Low altitude means any elevation less than or equal to 1,219 meters 
(4,000 feet).
    Manufacturer parts are parts produced or sold by the manufacturer of 
the motor vehicle or motor vehicle engine.



Sec.86.1603  General requirements.

    (a) Manufacturers of vehicles specified in Sec.86.1601 shall 
submit to the Administrator for approval the following altitude 
performance adjustment instructions.
    (1) Low-altitude adjustment instructions for vehicles certified to 
meet the appropriate high-altitude emission standards.
    (2) High-altitude adjustment instructions for vehicles certified to 
meet the appropriate low-altitude emission standards.
    (b) Manufacturers are not required to submit altitude adjustment 
instructions for vehicles equipped with systems or devices that 
compensate (in full or in part) the engine fuel metering system for air 
density changes. Manufacturers claiming this exemption must submit to 
the Administrator for approval a notification of the claim specifying 
the affected vehicles. The notification must also describe the 
compensating system used.
    (c) Manufacturers may request the Administrator to waive the 
application of this regulation for vehicles which potentially may never 
be operated at an altitude other than that for which they were designed 
(such as vehicles which are not offered for sale within the continental 
United States).
    (d) Manufacturers shall meet the requirements of paragraph (a), 
according to the following schedule:
    (1) Altitude adjustment instructions for all 1980 and earlier model 
year vehicles or engines shall be submitted to the Administrator within 
one (1) year of the effective date of this regulation.
    (2) Altitude adjustment instructions for 1982 and later model year 
vehicles or engines shall be submitted to the Administrator within 30 
days of the issuance of the certificate of conformity for those vehicles 
or engines. For vehicles or engines certified for the 1981 model year 
before the publication of this regulation, altitude adjustment 
instructions shall be submitted within 90 days of the publication of 
this regulation.
    (e) Failure to submit altitude performance adjustment instructions 
in accordance with this section is a violation of section 203(a)(3) of 
the Clean Air Act and may result in penalties as specified in section 
205 of the Clean Air Act. The Administrator may grant extensions of the 
schedule in paragraph (c) if the manufacturer submits a written request 
to the Administrator specifying the reasons for the need for the 
extension. Requests for an extension must be received by EPA at least 5 
working days prior to the submittal date contained in paragraph (d).
    (f) The adjustment instructions (including labels) that the 
Administrator approves under this subpart shall be made available by the 
manufacturer at no cost to service outlets and the general public. EPA 
encourages manufacturers to notify vehicle owners in high-altitude areas 
of the availability of high-altitude adjustments.
    (g) If altitude adjustments are performed according to the 
instructions approved by the Administrator, they will not be treated as 
violations of the tampering provisions of section 203(a) of the Act 
except as described below:



Sec.86.1604  Conditions for disapproval.

    (a) The Administrator shall not approve altitude performance 
adjustments that will:
    (1) Cause any regulated pollutant emission level to increase if the 
emission level exceeded the appropriate emission standard before 
adjustment was made.
    (2) Cause any regulated pollutant emission level to exceed the 
appropriate emission standard if the emission level did not exceed the 
emission standard before the adjustment was made.
    (3) For light-duty vehicles, light-duty trucks, motorcycles, heavy-
duty gasoline-fueled engines, cause any reduction of vehicle performance 
(as evaluated by the manufacturer) such that vehicle drivers will likely 
complain.

[[Page 886]]

    (4) Be of such technical complexity or require such complex, 
expensive, or exclusive equipment that a competent mechanic in an 
average service establishment cannot perform the adjustments correctly. 
Adjustment procedures should not require knowledge or training beyond 
that required to perform normal engine maintenance. All required 
equipment must be available to any service establishment at competitive 
cost.
    (5) Require the use of manufacturer parts, unless they are necessary 
to ensure emission control performance and unless the Administrator 
grants a waiver under section 207(c)(3)(B) of the Act.
    (6) Removes or defeats the parameter adjustment controls for the 
parameters listed in Sec. Sec.86.081-22(e)(1)(i) and 86.082-
22(e)(1)(i) for light-duty vehicles and light-duty trucks, and Sec.
86.428-80(d) for motorcycles unless:
    (i) The manufacturer determines that it is reasonable to restore the 
parameter adjustment control in use and provides appropriate instruction 
as part of the high-altitude performance adjustment instructions, or
    (ii) The manufacturer determines that is is not reasonable to 
restore the parameter adjustment control in use and alternatively 
includes on the label required in Sec.86.1606 a statement to the 
effect that the labeled vehicle can be adjusted but that adjustment to 
other than manufacturer specification may be considered violation of 
Federal law.
    (b) If the Administrator determines that the altitude performance 
adjustment instructions cannot be approved, the Administrator shall 
notify the manufacturer in writing of the disapproval. This notification 
shall explain the reasons for the disapproval.
    (1) Within 20 working days of the date of a notification of 
disapproval, the manufacturer may file a written appeal to the 
Administrator. The Administrator may allow additional oral or written 
testimony prior to rendering a final decision.
    (2) If the manufacturer files no appeal with the Administrator, the 
disapproval becomes final.
    (3) Within 30 days following the Administrator's final decision of 
disapproval, the manufacturer must submit new altitude performance 
adjustment instructions applying to all of the vehicles for which the 
disapproved instructions applied. If these new instructions are not 
submitted within 30 days, EPA may take action under sections 203(a)(3) 
and 205 of the Act. If the new altitude performance adjustment 
instructions are disapproved by the Administrator, the manufacturer may 
follow the appeal procedures under paragraphs (b)(1) and (b)(2) of this 
section.
    (c) If the Administrator makes a final decision to disapprove the 
new instructions, EPA may take action under sections 203(a)(3) and 205 
of the Act.

[[Page 889]]

part. Subpart R of this part is applicable only to those covered 
manufacturers as defined under the provisions of subpart R of this part. 
All provisions of this subpart S are applicable to vehicles certified 
pursuant to subpart R of this part, except as specifically noted in 
subpart R of this part.
    (f) ``Early'' Tier 2 LDVs, LDTs and MDPVs. Any LDV/LLDT which is 
certified to Tier 2 FTP exhaust standards prior to the 2004 model year, 
or any HLDT or MDPV which is certified to the Tier 2 FTP exhaust 
standards prior to the 2008 model year, to utilize alternate phase-in 
schedules and/or for purposes of generating and banking Tier 2 
NOX credits, must comply with all the exhaust emission 
requirements applicable to Tier 2 LDV/LLDTs or HLDT/ MDPVs, as 
applicable, under this subpart.
    (g) Interim non-Tier 2 LDVs, LDTs and MDPVs. Model year 2004-2008 
LDVs, LDTs and MDPVs, that do not comply with the Tier 2 FTP exhaust 
emission requirements (interim non-Tier 2 LDV/LLDTs and interim non-Tier 
2 HLDT/MDPVs) as permitted under the phase-in requirements of Sec.
86.1811-04(k) must comply with all applicable interim non-Tier 2 exhaust 
emission requirements contained in this subpart, including FTP exhaust 
emission requirements for all interim non-Tier 2 LDV/LLDTs and HLDT/

FR 59963, Oct. 6, 2000; 67 FR 72825, Dec. 6, 2002; 76 FR 19873, Apr. 8, 
2011]



Sec.86.1801-12  Applicability.

    (a) Applicability. The provisions of this subpart apply to certain 
types of new vehicles as described in this paragraph (a). Where the 
provisions apply for a type of vehicle, they apply for vehicles powered 
by any fuel, unless otherwise specified. In some cases, manufacturers of 
heavy-duty engines and vehicles can choose whether to meet the 
requirements of this subpart or the requirements of subpart A of this 
part; those provisions are therefore considered optional, but only to 
the extent that manufacturers comply with the other set of requirements. 
In cases where a provision applies only to a certain vehicle group based 
on its model year, vehicle class, motor fuel, engine type, or other 
distinguishing characteristics, the limited applicability is cited in 
the appropriate section. References in this subpart to 40 CFR part 86 
generally apply to Tier 2 and older vehicles, while references to 40 CFR 
part 1066 generally apply to Tier 3 and newer vehicles; see 40 CFR 
86.101 for detailed provisions related to this transition. The 
provisions of this subpart apply to certain vehicles as follows:
    (1) The provisions of this subpart apply for light-duty vehicles and 
light-duty trucks.
    (2) The provisions of this subpart apply for medium-duty passenger 
vehicles. The provisions of this subpart also apply for other complete 
heavy-duty vehicles at or below 14,000 pounds GVWR, except as follows:
    (i) The provisions of this subpart are optional for diesel-cycle 
vehicles through model year 2017; however, if you are using the 
provisions of Sec.86.1811-17(b)(9) or Sec.86.1816-18(b)(8) to 
transition to the Tier 3 exhaust emission standards, the provisions of 
this subpart are optional for those diesel-cycle vehicles until the 
start of the Tier 3 phase-in for those vehicles.
    (ii) [Reserved]
    (iii) The provisions of this subpart are optional for diesel-fueled 
Class 3 heavy-duty vehicles in a given model year if those vehicles are 
equipped with engines certified to the appropriate standards in Sec.
86.007-11 for which less than half of the engine family's sales for the 
model year in the United States

[[Page 890]]

are for complete Class 3 heavy-duty vehicles. This includes engines sold 
to all vehicle manufacturers. If you are the original manufacturer of 
the engine and the vehicle, base this showing on your sales information. 
If you manufacture the vehicle but are not the original manufacturer of 
the engine, you must use your best estimate of the original 
manufacturer's sales information.
    (3) The provisions of this subpart generally do not apply to 
incomplete heavy-duty vehicles or to complete vehicles above 14,000 
pounds GVWR (see subpart A of this part and 40 CFR parts 1036 and 1037). 
However, this subpart applies to such vehicles in the following cases:
    (i) Heavy duty vehicles above 14,000 pounds GVWR may be optionally 
certified to the exhaust emission standards in this subpart, including 
the greenhouse gas emission standards, if they are properly included in 
test group with similar vehicles at or below 14,000 pounds GVWR. 
Emission standards apply to these vehicles as if they were Class 3 
heavy-duty vehicles. The work factor for these vehicles may not be 
greater than the largest work factor that applies for vehicles in the 
test group that are at or below 14,000 pounds GVWR (see Sec.86.1819-
14).
    (ii) Incomplete heavy-duty vehicles at or below 14,000 pounds GVWR 
may be optionally certified to the exhaust emission standards in this 
subpart that apply for heavy-duty vehicles.
    (iii) The evaporative emission standards apply for incomplete heavy-
duty vehicles at or below 14,000 pounds GVWR. Evaporative emission 
standards also apply for complete and incomplete heavy-duty vehicles 
above 14,000 pounds GVWR as specified in 40 CFR 1037.103.
    (iv) Refueling emission standards apply for complete heavy-duty 
vehicles above 14,000 pounds GVWR as specified in 40 CFR 1037.103. All 
sizes of incomplete heavy-duty vehicles may be optionally certified to 
the refueling emission standards in this subpart.
    (v) The onboard diagnostic requirements in this subpart apply for 
incomplete vehicles at or below 14,000 pounds GVWR, but not for any 
vehicles above 14,000 pounds GVWR.
    (4) If you optionally certify vehicles to standards under this 
subpart, those vehicles are subject to all the regulatory requirements 
as if the standards were mandatory.
    (b) Relationship to subpart A of this part. Unless specified 
otherwise, if heavy-duty vehicles are not subject to provisions of this 
subpart or if manufacturers choose not to meet optional provisions of 
this subpart as described in paragraph (a) of this section, the engines 
installed in those vehicles must meet the corresponding requirements 
under subpart A of this part. If a vehicle and its installed engine 
comply with a mix of provisions from this subpart and from subpart A of 
this part, the vehicle must be certified under this subpart, and the 
engine does not need to be certified separately.
    (c) Clean alternative fuel conversions. The provisions of this 
subpart also apply to clean alternative fuel conversions as defined in 
40 CFR 85.502 of all vehicles described in paragraph (a) of this 
section.
    (d) Small-volume manufacturers. Special certification procedures are 
available for small-volume manufacturers as described in Sec.86.1838.
    (e) You. The term ``you'' in this subpart refers to manufacturers 
subject to the emission standards and other requirements of this 
subpart.
    (f) Vehicle. The term ``vehicle'', when used generically, does not 
exclude any type of vehicle for which the regulations apply (such as 
light-duty trucks).
    (g) Complete and incomplete vehicles. Several provisions in this 
subpart, including the applicability provisions described in this 
section, are different for complete and incomplete vehicles. We 
differentiate these vehicle types as described in Sec.86.085-20.
    (h) Applicability of provisions of this subpart to light-duty 
vehicles, light-duty trucks, medium-duty passenger vehicles, and heavy-
duty vehicles. Numerous sections in this subpart provide requirements or 
procedures applicable to a ``vehicle'' or ``vehicles.'' Unless otherwise 
specified or otherwise determined by the Administrator, the term 
``vehicle'' or ``vehicles'' in those provisions apply equally to light-
duty vehicles (LDVs), light-duty trucks (LDTs), medium-duty passenger 
vehicles (MDPVs),

[[Page 891]]

and heavy-duty vehicles (HDVs), as those terms are defined in Sec.
86.1803-01.
    (i) Applicability of provisions of this subpart to exhaust 
greenhouse gas emissions. Numerous sections in this subpart refer to 
requirements relating to ``exhaust emissions.'' Unless otherwise 
specified or otherwise determined by the Administrator, the term 
``exhaust emissions'' refers at a minimum to emissions of all pollutants 
described by emission standards in this subpart, including carbon 
dioxide (CO2), nitrous oxide (N2O), and methane 
(CH4).
    (j) Exemption from greenhouse gas emission standards for small 
businesses. (1) Manufacturers that qualify as a small business under the 
Small Business Administration regulations in 13 CFR part 121 are exempt 
from the greenhouse gas emission standards specified in Sec.86.1818-12 
and in associated provisions in this part and in part 600 of this 
chapter. This exemption applies to both U.S.-based and non-U.S.-based 
businesses. The following categories of businesses (with their 
associated NAICS codes) may be eligible for exemption based on the Small 
Business Administration size standards in 13 CFR 121.201.
    (i) Vehicle manufacturers (NAICS code 336111).
    (ii) Independent commercial importers (NAICS codes 811111, 811112, 
811198, 423110, 424990, and 441120).
    (iii) Alternate fuel vehicle converters (NAICS codes 335312, 336312, 
336322, 336399, 454312, 485310, and 811198).
    (2)(i) Effective for the 2013 and later model years, a manufacturer 
that would otherwise be exempt under the provisions of paragraph (j)(1) 
of this section may optionally comply with the greenhouse gas emission 
standards specified in Sec.86.1818. A manufacturer making this choice 
is required to comply with all the applicable standards and provisions 
in Sec.86.1818 and with all associated and applicable provisions in 
this part and in part 600 of this chapter.
    (ii) Such a manufacturer may optionally earn credits in the 2012 
model year by demonstrating fleet average CO2 emission levels 
below the fleet average CO2 standard that would have been 
applicable in model year 2012 if the manufacturer had not been exempt. 
Once the small business manufacturer opting into the greenhouse gas 
emission standards completes certification for the 2013 model year, that 
manufacturer will be eligible to generate greenhouse gas emission 
credits for their 2012 model year production, after the conclusion of 
the 2012 model year for that manufacturer. Manufacturers electing to 
earn these 2012 credits must comply with the model year reporting 
requirements in Sec.600.512-12 for that model year. The 2012 fleet 
average must be calculated according to Sec.600.510 and other 
applicable requirements in part 600 of this chapter, and 2012 credits 
must be calculated according to Sec.86.1865 and other applicable 
requirements in this part.
    (k) Conditional exemption from greenhouse gas emission standards. 
Manufacturers meeting the eligibility requirements described in 
paragraphs (k)(1) and (2) of this section may request a conditional 
exemption from compliance with the emission standards described in Sec.
86.1818-12(c) through (e) and associated provisions in this part and in 
part 600 of this chapter. A conditional exemption under this paragraph 
(k) may be requested for the 2012 through 2016 model years. The terms 
``sales'' and ``sold'' as used in this paragraph (k) shall mean vehicles 
produced for U.S. sale, where ``U.S.'' means the states and territories 
of the United States. For the purpose of determining eligibility the 
sales of related companies shall be aggregated according to the 
provisions of Sec.86.1838-01(b)(3) or, if a manufacturer has been 
granted operational independence status under Sec.86.1838(d), 
eligibility shall be based on vehicle production of that manufacturer.
    (1) Eligibility requirements. Eligibility as determined in this 
paragraph (k) shall be based on the total sales of combined passenger 
automobiles and light trucks. Manufacturers must meet one of the 
requirements in paragraph (k)(1)(i) or (ii) of this section to initially 
qualify for this exemption.
    (i) A manufacturer with 2008 or 2009 model year sales of more than 
zero and fewer than 5,000 is eligible for a conditional exemption from 
the greenhouse gas emission standards described in Sec.86.1818-12 
paragraphs (c) through (e).

[[Page 892]]

    (ii) A manufacturer with 2008 or 2009 model year sales of more than 
zero and fewer than 5,000 while under the control of another 
manufacturer, where those 2008 or 2009 model year vehicles bore the 
brand of the producing manufacturer but were sold by or otherwise under 
the control of another manufacturer, and where the manufacturer 
producing the vehicles became independent no later than December 31, 
2010, is eligible for a conditional exemption from the greenhouse gas 
emission standards described in Sec.86.1818-12 paragraphs (c) through 
(e).
    (2) Maintaining eligibility for exemption from greenhouse gas 
emission standards. To remain eligible for exemption under this 
paragraph (k) the manufacturer's average sales for the three most recent 
consecutive model years must remain below 5,000. If a manufacturer's 
average sales for the three most recent consecutive model years exceeds 
4999, the manufacturer will no longer be eligible for exemption and must 
meet applicable emission standards according to the provisions in this 
paragraph (k)(2).
    (i) If a manufacturer's average sales for three consecutive model 
years exceeds 4999, and if the increase in sales is the result of 
corporate acquisitions, mergers, or purchase by another manufacturer, 
the manufacturer shall comply with the emission standards described in 
Sec.86.1818-12 paragraphs (c) through (e), as applicable, beginning 
with the first model year after the last year of the three consecutive 
model years.
    (ii) If a manufacturer's average sales for three consecutive model 
years exceeds 4999 and is less than 50,000, and if the increase in sales 
is solely the result of the manufacturer's expansion in vehicle 
production, the manufacturer shall comply with the emission standards 
described in Sec.86.1818-12 paragraphs (c) through (e), as applicable, 
beginning with the second model year after the last year of the three 
consecutive model years.
    (iii) If a manufacturer's average sales for three consecutive model 
years exceeds 49,999, the manufacturer shall comply with the emission 
standards described in Sec.86.1818-12 paragraphs (c) through (e), as 
applicable, beginning with the first model year after the last year of 
the three consecutive model years.
    (3) Requesting the conditional exemption from standards. To be 
exempted from the standards described in Sec.86.1818-12(c) through 
(e), the manufacturer must submit a declaration to EPA containing a 
detailed written description of how the manufacturer qualifies under the 
provisions of this paragraph (k). The declaration must describe 
eligibility information that includes the following: model year 2008 and 
2009 sales, sales volumes for each of the most recent three model years, 
detailed information regarding ownership relationships with other 
manufacturers, details regarding the application of the provisions of 
Sec.86.1838-01(b)(3) regarding the aggregation of sales of related 
companies, and documentation of good-faith efforts made by the 
manufacturer to purchase credits from other manufacturers. This 
declaration must be signed by a chief officer of the company, and must 
be made prior to each model year for which the exemption is requested. 
The declaration must be submitted to EPA at least 30 days prior to the 
introduction into commerce of any vehicles for each model year for which 
the exemption is requested, but not later than December of the calendar 
year prior to the model year for which exemption is requested. A 
conditional exemption will be granted when EPA approves the exemption 
declaration. The declaration must be sent to the Environmental 
Protection Agency at the following address: Director, Compliance and 
Innovative Strategies Division, U.S. Environmental Protection Agency, 
2000 Traverwood Drive, Ann Arbor, Michigan 48105.

Sec.86.1802-01  Section numbering; construction.

    (a) Section numbering. The model year of initial applicability is 
indicated by the section number. The two digits following the hyphen 
designate the first model year for which a section is applicable. The 
section continues to apply to subsequent model years unless a later 
model year section is adopted.

[[Page 893]]

Example: Section 86.18xx-10 applies to model year 2010 and later 
vehicles. If a Sec.86.18xx-17 is promulgated, it would apply beginning 
with the 2017 model year; Sec.86.18xx-10 would apply only to model 
years 2010 through 2016, except as specified in Sec.86.18xx-17.
    (b) A section reference without a model year suffix refers to the 
section applicable for the appropriate model year.
    (c) If a regulation in this subpart references a section that has 
been superseded or no longer exists, this should be understood as a 
reference to the same section for the appropriate model year. For 
example, if a regulation in this subpart refers to Sec.86.1845-01, it 
should be taken as a reference to Sec.86.1845-04 or any later version 
of Sec.86.1845 that applies for the appropriate model year. However, 
this does not apply if the reference to a superseded section 
specifically states that the older provision applies instead of any 
updated provisions from the section in effect for the current model 
year; this occurs most often as part of the transition to new emission 
standards.

alternative useful life periods approved by the Administrator under 
Sec.86.1805-01(c). The determination of durability useful life shall 
exclude any standard and related useful life mileage for which the 
manufacturer has obtained a waiver of emission data submission 
requirements under Sec.86.1829-01.

a motor vehicle that is either--
    (i) An ambulance or a fire truck; or
    (ii) A vehicle that we have determined will likely be used in 
emergency situations where emission control function or malfunction may 
cause a significant risk to human life. For example, we would consider a 
pickup truck that is certain to be retrofitted with a slip-on 
firefighting module to be an emergency vehicle, even though it was not 
initially designed to be a fire truck. Also, a mobile command center 
that is unable to manually regenerate its DPF while on duty could be an 
emergency vehicle. In making this determination, we may consider any 
factor that has an effect on the totality of the actual risk to human 
life. For example, we may consider how frequently a vehicle will be used 
in emergency situations or how likely it is that the emission controls 
will cause a significant risk to human life when the vehicle is used in 
emergency situations. We would not consider the pickup truck in the 
example above to be an emergency vehicle if there is merely a 
possibility (rather than a certainty) that the vehicle will be 
retrofitted with a slip-on firefighting module.

standard are considered as ``negative credits.'' In addition, 
``projected credits'' refer to emission credits based on the projected 
U.S. production volume of the test group. ``Reserved credits'' are 
emission credits generated within a model year waiting to be reported to 
EPA at the end of the model year. ``Actual credits'' refer to emission 
credits based on actual U.S. production volumes as contained in the end-

Sec.86.1805-04  Useful life.

    (a) Except as required under paragraph (b) of this section or 
permitted under paragraphs (d), (e) and (f) of this section, the full 
useful life for all LDVs, LDT1s and LDT2s is a period of use of 10 years 
or 120,000 miles, whichever occurs first. For all HLDTs, MDPVs, and 
complete heavy-duty vehicles full useful life is a period of 11 years or 
120,000 miles, whichever occurs first. This full useful life applies to 
all exhaust, evaporative and refueling emission requirements except for 
standards which are specified to only be applicable at the time of 
certification.
    (b) Manufacturers may elect to optionally certify a test group to 
the Tier 2 exhaust emission standards for 150,000 miles to gain 
additional NOX credits, as permitted in Sec.86.1860-04(g), 
or to opt out of intermediate life standards as permitted in Sec.
86.1811-04(c). In such cases, useful life is a period of use of 15 years 
or 150,000 miles, whichever occurs first, for all exhaust, evaporative 
and refueling emission requirements except for cold CO standards and 
standards which are applicable only at the time of certification.
    (c) Where intermediate useful life exhaust emission standards are 
applicable, such standards are applicable for five years or 50,000 
miles, whichever occurs first.
    (d) Where cold CO standards are applicable, the useful life 
requirement for compliance with the cold CO standard only, is 5 years or 
50,000 miles, whichever occurs first.
    (e) Where LDVs, LDT1s and LDT2s of the 2003 or earlier model years 
are certified to Tier 2 exhaust emission standards for purposes of 
generating early Tier 2 NOX credits, manufacturers may 
certify those vehicles to full useful lives of 100,000 miles in lieu of 
the otherwise required 120,000 mile full useful lives, as provided under 
Sec.86.1861-04(c)(4).
    (f) For interim non-Tier 2 LDV/LLDTs, the useful life requirement 
for exhaust, evaporative and refueling emissions is 10 years or 100,000 
miles, whichever occurs first.

life requirement for compliance with the cold temperature NMHC standard 
only is as follows:
    (1) For LDV/LLDTs, 10 years or 120,000 miles, whichever occurs 
first.
    (2) For HLDT/MDPVs, 11 years or 120,000 miles, whichever occurs 
first.

Sec.86.1805-12  Useful life.

    (a) Except as permitted under paragraph (b) of this section or 
required under paragraphs (c) and (d) of this section, the full useful 
life for all LDVs and LLDTs is a period of use of 10 years or 120,000

MDPVs, and complete heavy-duty vehicles is a period of 11 years or 
120,000 miles, whichever occurs first. These full useful life values 
apply to all exhaust, evaporative and refueling emission requirements 
except for standards which are specified to only be applicable at the 
time of certification. These full useful life requirements also apply to 
all air conditioning leakage credits, air conditioning efficiency 
credits, and other credit programs used by the manufacturer to comply 
with the fleet average CO2 emission standards in Sec.
86.1818-12.
    (b) Manufacturers may elect to optionally certify a test group to 
the Tier 2 exhaust emission standards for 150,000 miles to gain 
additional NOX credits, as permitted in Sec.86.1860-04(g), 
or to opt out of intermediate life standards as permitted in Sec.

which are applicable only at the time of certification.
    (c) Where intermediate useful life exhaust emission standards are 
applicable, such standards are applicable for five years or 50,000 
miles, whichever occurs first.
    (d) Where cold CO standards are applicable, the useful life 
requirement for compliance with the cold CO standard only, is 5 years or 
50,000 miles, whichever occurs first.

[75 FR 25685, May 7, 2010]



Sec.86.1805-17  Useful life.

    (a) General provisions. The useful life values specified in this 
section apply for all exhaust, evaporative, refueling, and OBD emission 
requirements described in this subpart, except for standards that are 
specified to apply only at certification. These useful life requirements 
also apply to all air conditioning leakage credits, air conditioning 
efficiency credits, and other credit programs used by the manufacturer 
to comply with the fleet-average CO2 emission standards in 
Sec.86.1818. Useful life values are specified as a given number of 
calendar years or miles of driving, whichever comes first.
    (b) Greenhouse gas pollutants. The emission standards in Sec.
86.1818 apply for a useful life of 10 years or 120,000 miles for LDV and 
LLDT and 11 years or 120,000 miles for HLDT and MDPV. For non-MDPV 
heavy-duty vehicles, the emission standards in Sec.86.1819 apply for a 
useful life of 11 years or 120,000 miles through model year 2020, and 
for a useful life of 15 years or 150,000 miles in model year 2021 and 
later. Manufacturers may certify based on the useful life as specified 
in paragraph (d) of this section if it is different than the useful life 
specified in this paragraph (b).
    (c) Cold temperature emission standards. The cold temperature NMHC 
emission standards in Sec.86.1811 apply for a useful life of 10 years 
or 120,000 miles for LDV and LLDT, and 11 years or 120,000 miles for 
HLDT and HDV. The cold temperature CO emission standards in Sec.
86.1811 apply for a useful life of 5 years or 50,000 miles.
    (d) Criteria pollutants. The useful life provisions of this 
paragraph (d) apply for all emission standards not covered by paragraph 
(b) or (c) of this section. Except as specified in paragraph (f) of this 
section and in Sec. Sec.86.1811, 86.1813, and 86.1816, the useful life 
for LDT2, HLDT, MDPV, and HDV is 15 years or 150,000 miles. The useful 
life for LDV and LDT1 is 10 years or 120,000 miles. Manufacturers may 
optionally certify LDV and LDT1 to a useful life of 15 years or 150,000 
miles, in which case the longer useful life would apply for all the 
standards and requirements covered by this paragraph (d).
    (e) Intermediate useful life. Where exhaust emission standards are 
specified for an intermediate useful life, these standards apply for 
five years or 50,000 miles.
    (f) Interim provisions. The useful life provisions of Sec.86.1805-
12 apply for vehicles not yet subject to Tier 3 requirements. For 
example, vehicles above 6,000 pounds GVWR are not subject to the useful 
life provisions in this section until model year 2019 unless 
manufacturers voluntarily certify to the Tier 3 requirements earlier 
than the regulations require. Also, where the transition to Tier 3 
standards involves a phase-in percentage for a given standard, vehicles 
not included as part of the phase-in portion of the fleet continue to be 
subject to the useful life provisions of Sec.86.1805-12 with respect 
to that standard. The useful life values for a set of vehicles may be 
different for exhaust and evaporative emission standards in 2021 and 
earlier model years; if vehicles have different useful life values for 
evaporative and exhaust emission standards, the evaporative useful life 
applies for the OBD requirements related to the leak standard and the 
exhaust useful life applies for all other OBD requirements.

FR 73983, Oct. 25, 2016]



Sec.86.1806-05  Onboard diagnostics.

    (a) General. (1) Except as provided by paragraph (a)(2) of this 
section, all light-duty vehicles, light-duty trucks and complete heavy-
duty vehicles weighing 14,000 pounds GVWR or less (including MDPVs) must 
be equipped with an onboard diagnostic (OBD) system capable of 
monitoring all emission-related powertrain systems or

[[Page 910]]

components during the applicable useful life of the vehicle. All systems 
and components required to be monitored by these regulations must be 
evaluated periodically, but no less frequently than once per applicable 
certification test cycle as defined in paragraphs (a) and (d) of 
Appendix I of this part, or similar trip as approved by the 
Administrator. Emissions of CO2, CH4, and 
N2O are not required to be monitored by the OBD system.
    (2) Diesel fueled MDPVs and heavy-duty vehicles weighing 14,000 
pounds GVWR or less that are not MDPVs must meet the OBD requirements of 
this section according to the phase-in schedule in paragraph (l) of this 
section. Paragraph (l) of this section does not apply to Otto-cycle 
MDPVs.
    (3) An OBD system demonstrated to fully meet the requirements in, 
through model year 2006, Sec.86.004-17 and, for model years 2007 and 
later, Sec.86.007-17 may be used to meet the requirements of this 
section, provided that such an OBD system also incorporates appropriate 
transmission diagnostics as may be required under this section, and 
provided that the Administrator finds that a manufacturer's decision to 
use the flexibility in this paragraph (a)(3) is based on good 
engineering judgement.
    (b) Malfunction descriptions. The OBD system must detect and 
identify malfunctions in all monitored emission-related powertrain 
systems or components according to the following malfunction definitions 
as measured and calculated in accordance with test procedures set forth 
in subpart B of this part (chassis-based test procedures), excluding 
those test procedures defined as ``Supplemental'' test procedures in 
Sec.86.004-2 and codified in Sec. Sec.86.158, 86.159, and 86.160. 
For clean alternative fuel conversion manufacturers, your OBD system is 
expected to detect and identify malfunctions in all monitored emission-
related powertrain systems or components according to the malfunction 
definitions described in this paragraph (b) as measured and calculated 
in accordance with the chassis-based test procedures set forth in 
subpart B of this part to the extent feasible, excluding the elements of 
the Supplemental FTP (see Sec.86.1803). However, at a minimum, systems 
must detect and identify malfunctions as described in paragraph (k)(7) 
of this section.
    (1) Catalysts and particulate traps--(i) Otto-cycle. Catalyst 
deterioration or malfunction before it results in an increase in NMHC 
emissions 1.5 times the NMHC standard or FEL, as compared to the NMHC 
emission level measured using a representative 4000 mile catalyst 
system.
    (ii) Diesel. (A) If equipped, catalyst deterioration or malfunction 
before it results in exhaust emissions exceeding 1.5 times the 
applicable standard or FEL for NOX or PM. This requirement 
applies only to reduction catalysts; monitoring of oxidation catalysts 
is not required. This monitoring need not be done if the manufacturer 
can demonstrate that deterioration or malfunction of the system will not 
result in exceedance of the threshold.
    (B) If equipped with a particulate trap, catastrophic failure of the 
device must be detected. Any particulate trap whose complete failure 
results in exhaust emissions exceeding 1.5 times the applicable standard 
or FEL for NOX or PM must be monitored for such catastrophic 
failure. This monitoring need not be done if the manufacturer can 
demonstrate that a catastrophic failure of the system will not result in 
exceedance of the threshold.
    (2) Engine misfire--(i) Otto-cycle. Engine misfire resulting in 
exhaust emissions exceeding 1.5 times the applicable standard or FEL for 
NMHC, CO or NOX; and any misfire capable of damaging the 
catalytic converter.
    (ii) Diesel. Lack of cylinder combustion must be detected.
    (3) Oxygen sensors. If equipped, oxygen sensor deterioration or 
malfunction resulting in exhaust emissions exceeding 1.5 times the 
applicable standard or FEL for NMHC, CO or NOX.
    (4) Evaporative leaks. If equipped, any vapor leak in the 
evaporative and/or refueling system (excluding the tubing and 
connections between the purge valve and the intake manifold) greater 
than or equal in magnitude to a leak caused by a 0.040 inch diameter 
orifice; an absence of evaporative purge air flow from the complete 
evaporative emission control system. On vehicles with fuel tank capacity 
greater than 25

[[Page 911]]

gallons, the Administrator may, following a request from the 
manufacturer, revise the size of the orifice to the smallest orifice 
feasible, based on test data, if the most reliable monitoring method 
available cannot reliably detect a system leak equal to a 0.040 inch 
diameter orifice.
    (5) Other emission control systems. Any deterioration or malfunction 
occurring in a powertrain system or component directly intended to 
control emissions, including but not necessarily limited to, the exhaust 
gas recirculation (EGR) system, if equipped, the secondary air system, 
if equipped, and the fuel control system, singularly resulting in 
exhaust emissions exceeding 1.5 times the applicable emission standard 
or FEL for NMHC, CO, NOX, or diesel PM. For vehicles equipped 
with a secondary air system, a functional check, as described in 
paragraph (b)(6) of this section, may satisfy the requirements of this 
paragraph provided the manufacturer can demonstrate that deterioration 
of the flow distribution system is unlikely. This demonstration is 
subject to Administrator approval and, if the demonstration and 
associated functional check are approved, the diagnostic system must 
indicate a malfunction when some degree of secondary airflow is not 
detectable in the exhaust system during the check. For vehicles equipped 
with positive crankcase ventilation (PCV), monitoring of the PCV system 
is not necessary provided the manufacturer can demonstrate to the 
Administrator's satisfaction that the PCV system is unlikely to fail.
    (6) Other emission-related powertrain components. Any other 
deterioration or malfunction occurring in an electronic emission-related 
powertrain system or component not otherwise described in paragraphs 
(b)(1) through (b)(5) of this section that either provides input to or 
receives commands from the on-board computer and has a measurable impact 
on emissions; monitoring of components required by this paragraph (b)(6) 
must be satisfied by employing electrical circuit continuity checks and 
rationality checks for computer input components (input values within 
manufacturer specified ranges based on other available operating 
parameters), and functionality checks for computer output components 
(proper functional response to computer commands) except that the 
Administrator may waive such a rationality or functionality check where 
the manufacturer has demonstrated infeasibility. Malfunctions are 
defined as a failure of the system or component to meet the electrical 
circuit continuity checks or the rationality or functionality checks.
    (7) Performance of OBD functions. Oxygen sensor or any other 
component deterioration or malfunction which renders that sensor or 
component incapable of performing its function as part of the OBD system 
must be detected and identified on vehicles so equipped.
    (8) Hybrid electric vehicles. For Tier 2 and interim non-Tier 2 
hybrid electric vehicles (HEVs) only. Unless added to HEVs in compliance 
with other requirements of this section, or unless otherwise approved by 
the Administrator:
    (i) The manufacturer must equip each HEV with a maintenance 
indicator consisting of a light that must activate automatically by 
illuminating the first time the minimum performance level is observed 
for each battery system component. Possible battery system components 
requiring monitoring are: battery water level, temperature control, 
pressure control, and other parameters critical for determining battery 
condition.
    (ii) [Reserved]
    (iii) The manufacturer must equip each HEV with a separate odometer 
or other device subject to the approval of the Administrator that can 
accurately measure the mileage accumulation on the engines used in these 
vehicles.
    (c) Malfunction indicator light (MIL). The OBD system must 
incorporate a malfunction indicator light (MIL) readily visible to the 
vehicle operator. When illuminated, the MIL must display ``Check 
Engine,'' ``Service Engine Soon,'' a universally recognizable engine 
symbol, or a similar phrase or symbol approved by the Administrator. A 
vehicle should not be equipped with more than one general purpose 
malfunction indicator light for emission-related problems; separate 
specific purpose warning lights (e.g. brake system, fasten seat belt, 
oil pressure, etc.) are permitted. The use of red for the OBD-

[[Page 912]]

related malfunction indicator light is prohibited.
    (d) MIL illumination. (1) The MIL must illuminate and remain 
illuminated when any of the conditions specified in paragraph (b) of 
this section are detected and verified, or whenever the engine control 
enters a default or secondary mode of operation considered abnormal for 
the given engine operating conditions. The MIL must blink once per 
second under any period of operation during which engine misfire is 
occurring and catalyst damage is imminent. If such misfire is detected 
again during the following driving cycle (i.e., operation consisting of, 
at a minimum, engine start-up and engine shut-off) or the next driving 
cycle in which similar conditions are encountered, the MIL must maintain 
a steady illumination when the misfire is not occurring and then remain 
illuminated until the MIL extinguishing criteria of this section are 
satisfied. The MIL must also illuminate when the vehicle's ignition is 
in the ``key-on'' position before engine starting or cranking and 
extinguish after engine starting if no malfunction has previously been 
detected. If a fuel system or engine misfire malfunction has previously 
been detected, the MIL may be extinguished if the malfunction does not 
reoccur during three subsequent sequential trips during which similar 
conditions are encountered and no new malfunctions have been detected. 
Similar conditions are defined as engine speed within 375 rpm, engine 
load within 20 percent, and engine warm-up status equivalent to that 
under which the malfunction was first detected. If any malfunction other 
than a fuel system or engine misfire malfunction has been detected, the 
MIL may be extinguished if the malfunction does not reoccur during three 
subsequent sequential trips during which the monitoring system 
responsible for illuminating the MIL functions without detecting the 
malfunction, and no new malfunctions have been detected. Upon 
Administrator approval, statistical MIL illumination protocols may be 
employed, provided they result in comparable timeliness in detecting a 
malfunction and evaluating system performance, i.e., three to six 
driving cycles would be considered acceptable.
    (2)(i) For interim non-Tier 2 and Tier 2 LDV/LLDTs and HLDT/MDPVs 
produced through the 2007 model year, upon a manufacturer's written 
request, EPA will consider allowing the use of an on-board diagnostic 
system during the certification process that functions properly on low-
sulfur gasoline but indicates sulfur-induced passes when exposed to high 
sulfur gasoline. After the 2007 model year, this provision can be used 
only for interim non-Tier 2 and Tier 2 LDV/LLDTs and HLDT/MDPVs 
introduced into commerce in American Samoa, Guam, and the Commonwealth 
of the Northern Mariana Islands, but this provision only can be used for 
such vehicles in any of those locations if low sulfur gasoline is 
determined by the Administrator to be unavailable in that specific 
location.
    (ii) For interim non-Tier 2 and Tier 2 LDV/LLDTs and HLDT/MDPVs, if 
vehicles produced through the 2007 model year exhibit illuminations of 
the emission control diagnostic system malfunction indicator light due 
to high sulfur gasoline, EPA will consider, upon a manufacturer's 
written request, allowing modifications to such vehicles on a case-by-
case basis so as to eliminate the sulfur induced illumination. After the 
2007 model year, this provision can be used only for interim non-Tier 2 
and Tier 2 LDV/LLDTs and HLDT/MDPVs introduced into commerce in American 
Samoa, Guam, and the Commonwealth of the Northern Mariana Islands, but 
this provision only can be used for such vehicles in any of those 
locations if low sulfur gasoline is determined by the Administrator to 
be unavailable in that specific location.
    (e) Storing of computer codes. The OBD system shall record and store 
in computer memory diagnostic trouble codes and diagnostic readiness 
codes indicating the status of the emission control system. These codes 
shall be available through the standardized data link connector per 
specifications as referenced in paragraph (h) of this section.
    (1) A diagnostic trouble code must be stored for any detected and 
verified malfunction causing MIL illumination.

[[Page 913]]

The stored diagnostic trouble code must identify the malfunctioning 
system or component as uniquely as possible. At the manufacturer's 
discretion, a diagnostic trouble code may be stored for conditions not 
causing MIL illumination. Regardless, a separate code should be stored 
indicating the expected MIL illumination status (i.e., MIL commanded 
``ON,'' MIL commanded ``OFF'').
    (2) For a single misfiring cylinder, the diagnostic trouble code(s) 
must uniquely identify the cylinder, unless the manufacturer submits 
data and/or engineering evaluations which adequately demonstrate that 
the misfiring cylinder cannot be reliably identified under certain 
operating conditions. For diesel vehicles only, the specific cylinder 
for which combustion cannot be detected need not be identified if new 
hardware would be required to do so. The diagnostic trouble code must 
identify multiple misfiring cylinder conditions; under multiple misfire 
conditions, the misfiring cylinders need not be uniquely identified if a 
distinct multiple misfire diagnostic trouble code is stored.
    (3) The diagnostic system may erase a diagnostic trouble code if the 
same code is not re-registered in at least 40 engine warm-up cycles, and 
the malfunction indicator light is not illuminated for that code.
    (4) Separate status codes, or readiness codes, must be stored in 
computer memory to identify correctly functioning emission control 
systems and those emission control systems which require further vehicle 
operation to complete proper diagnostic evaluation. A readiness code 
need not be stored for those monitors that can be considered 
continuously operating monitors (e.g., misfire monitor, fuel system 
monitor, etc.). Readiness codes should never be set to ``not ready'' 
status upon key-on or key-off; intentional setting of readiness codes to 
``not ready'' status via service procedures must apply to all such 
codes, rather than applying to individual codes. Subject to 
Administrator approval, if monitoring is disabled for a multiple number 
of driving cycles (i.e., more than one) due to the continued presence of 
extreme operating conditions (e.g., ambient temperatures below 40 
[deg]F, or altitudes above 8000 feet), readiness for the subject 
monitoring system may be set to ``ready'' status without monitoring 
having been completed. Administrator approval shall be based on the 
conditions for monitoring system disablement, and the number of driving 
cycles specified without completion of monitoring before readiness is 
indicated.
    (f) Available diagnostic data. (1) Upon determination of the first 
malfunction of any component or system, ``freeze frame'' engine 
conditions present at the time must be stored in computer memory. Should 
a subsequent fuel system or misfire malfunction occur, any previously 
stored freeze frame conditions must be replaced by the fuel system or 
misfire conditions (whichever occurs first). Stored engine conditions 
must include, but are not limited to: engine speed, open or closed loop 
operation, fuel system commands, coolant temperature, calculated load 
value, fuel pressure, vehicle speed, air flow rate, and intake manifold 
pressure if the information needed to determine these conditions is 
available to the computer. For freeze frame storage, the manufacturer 
must include the most appropriate set of conditions to facilitate 
effective repairs. If the diagnostic trouble code causing the conditions 
to be stored is erased in accordance with paragraph (d) of this section, 
the stored engine conditions may also be erased.
    (2) The following data in addition to the required freeze frame 
information must be made available on demand through the serial port on 
the standardized data link connector, if the information is available to 
the on-board computer or can be determined using information available 
to the on-board computer: Diagnostic trouble codes, engine coolant 
temperature, fuel control system status (closed loop, open loop, other), 
fuel trim, ignition timing advance, intake air temperature, manifold air 
pressure, air flow rate, engine RPM, throttle position sensor output 
value, secondary air status (upstream, downstream, or atmosphere), 
calculated load value, vehicle speed, and fuel pressure. The signals 
must be provided in standard units based on SAE

[[Page 914]]

specifications incorporated by reference in paragraph (h) of this 
section. Actual signals must be clearly identified separately from 
default value or limp home signals.
    (3) For all OBD systems for which specific on-board evaluation tests 
are conducted (catalyst, oxygen sensor, etc.), the results of the most 
recent test performed by the vehicle, and the limits to which the system 
is compared must be available through the standardized data link 
connector per the appropriate standardized specifications as referenced 
in paragraph (h) of this section.
    (4) Access to the data required to be made available under this 
section shall be unrestricted and shall not require any access codes or 
devices that are only available from the manufacturer.
    (g) Exceptions. The OBD system is not required to evaluate systems 
or components during malfunction conditions if such evaluation would 
result in a risk to safety or failure of systems or components. 
Additionally, the OBD system is not required to evaluate systems or 
components during operation of a power take-off unit such as a dump bed, 
snow plow blade, or aerial bucket, etc.
    (h) Incorporation by reference. The following additional 
requirements apply based on industry standard specifications, which are 
incorporated by reference in Sec.86.1:
    (1) The following requirements apply for standardized on-board to 
off-board communications:
    (i) Starting in model year 2008, light-duty vehicles and light-duty 
trucks must comply with ISO 15765-4:2005(E), ``Road Vehicles-Diagnostics 
on Controller Area Network (CAN)--Part 4: Requirements for emission-
related systems'', January 15, 2005.
    (ii) Starting in model year 2008, heavy-duty vehicles must comply 
with the protocol described in paragraph (h)(1)(i) of this section, or 
the following set of SAE standards: SAE J1939-11, Revised October 1999; 
SAE J1939-13, July 1999; SAE J1939-21, Revised April 2001; SAE J1939-31, 
Revised December 1997; SAE J1939-71, Revised January 2008; SAE J1939-73, 
Revised September 2006; SAE J1939-81, May 2003.
    (iii) Note that for model years 1996 through 2007 manufacturers 
could instead comply with the protocols specified in SAE J1850, ISO 
9141-2, or ISO 14230-4.
    (2) Light-duty vehicles and light-duty trucks must meet the 
following additional specifications:
    (i) Basic diagnostic data (as specified in Sec. Sec.86.094-17(e) 
and (f)) shall be provided in the format and units in SAE J1979 ``E/E 
Diagnostic Test Modes--Equivalent to ISO/DIS 15031-5: Revised, May 2007.
    (ii) Diagnostic trouble codes shall be consistent with SAE J2012 
``Diagnostic Trouble Code Definitions--Equivalent to ISO/DIS 15031-6: 
April 30, 2002'', (Revised, April 2002).
    (iii) The connection interface between the OBD system and test 
equipment and diagnostic tools shall meet the functional requirements of 
SAE J1962 ``Diagnostic Connector--Equivalent to ISO/DIS 15031-3: 
December 14, 2001'' (Revised, April 2002).
    (iv) SAE J1930, Revised April 2002. All acronyms, definitions and 
abbreviations shall be formatted according to this industry standard. 
Alternatively, manufacturers may use SAE J2403, Revised August 2007.
    (v) All equipment used to interface, extract, and display OBD-
related information shall meet SAE J1978 ``OBD II Scan Tool'' Equivalent 
to ISO 15031-4: December 14, 2001'', (Revised, April 2002).
    (i) Deficiencies and alternative fueled vehicles. Upon application 
by the manufacturer, the Administrator may accept an OBD system as 
compliant even though specific requirements are not fully met. Such 
compliances without meeting specific requirements, or deficiencies, will 
be granted only if compliance would be infeasible or unreasonable 
considering such factors as, but not limited to: Technical feasibility 
of the given monitor and lead time and production cycles including 
phase-in or phase-out of vehicle designs and programmed upgrades of 
computers. Unmet requirements should not be carried over from the 
previous model year except where unreasonable hardware or software 
modifications would be necessary to correct the deficiency, and the 
manufacturer has demonstrated an

[[Page 915]]

acceptable level of effort toward compliance as determined by the 
Administrator. Furthermore, EPA will not accept any deficiency requests 
that include the complete lack of a major diagnostic monitor (``major'' 
diagnostic monitors being those for exhaust aftertreatment devices, 
oxygen sensor, air-fuel ratio sensor, NOX sensor, engine 
misfire, evaporative leaks, and diesel EGR, if equipped), with the 
possible exception of the special provisions for alternative fueled 
engines. For alternative fueled vehicles (e.g., natural gas, liquefied 
petroleum gas, methanol, ethanol), manufacturers may request the 
Administrator to waive specific monitoring requirements of this section 
for which monitoring may not be reliable with respect to the use of the 
alternative fuel. At a minimum, alternative fuel engines must be 
equipped with an OBD system meeting OBD requirements to the extent 
feasible as approved by the Administrator.
    (j) California OBDII compliance option. Manufacturers may comply 
with California's OBD requirements instead of meeting the requirements 
of this section as follows:
    (1) Through the 2006 model year, demonstration of compliance with 
California OBDII requirements (Title 13 California Code of Regulations 
Sec.1968.2 (13 CCR 1968.2)), as modified, approved and filed on April 
21, 2003 (incorporated by reference, see Sec.86.1), shall satisfy the 
requirements of this section, except that compliance with 13 CCR 
1968.2(e)(4.2.2)(C), pertaining to 0.02 inch evaporative leak detection, 
and 13 CCR 1968.2(d)(1.4), pertaining to tampering protection, are not 
required to satisfy the requirements of this section. Also, the 
deficiency provisions of 13 CCR 1968.2(i) do not apply. In addition, 
demonstration of compliance with 13 CCR 1968.2(e)(16.2.1)(C), to the 
extent it applies to the verification of proper alignment between the 
camshaft and crankshaft, applies only to vehicles equipped with variable 
valve timing.
    (2) For 2007 through 2012 model year vehicles, demonstration of 
compliance with California OBD II requirements (Title 13 California Code 
of Regulations Sec.1968.2 (13 CCR 1968.2)), approved on November 9, 
2007 (incorporated by reference, see Sec.86.1), shall satisfy the 
requirements of this section, except that compliance with 13 CCR 
1968.2(e)(4.2.2)(C), pertaining to 0.02 inch evaporative leak detection, 
and 13 CCR 1968.2(d)(1.4), pertaining to tampering protection, are not 
required to satisfy the requirements of this section. Also, the 
deficiency provisions of 13 CCR 1968.2(k) do not apply. In addition, 
demonstration of compliance with 13 CCR 1968.2(e)(15.2.1)(C), to the 
extent it applies to the verification of proper alignment between the 
camshaft and crankshaft, applies only to vehicles equipped with variable 
valve timing.
    (3) Beginning with the 2013 model year, manufacturers may 
demonstrate compliance with California's 2013 OBD requirements as 
described in Sec.86.1806-17(a).
    (4) For all model years, the deficiency provisions of paragraph (i) 
of this section and the evaporative leak detection requirement of 
paragraph (b)(4) of this section, if applicable, apply to manufacturers 
selecting this paragraph for demonstrating compliance.
    (k) Certification. For test groups required to have an OBD system, 
certification will not be granted if, for any test vehicle approved by 
the Administrator in consultation with the manufacturer, the malfunction 
indicator light does not illuminate under any of the following 
circumstances, unless the manufacturer can demonstrate that any 
identified OBD problems discovered during the Administrator's evaluation 
will be corrected on production vehicles.
    (1)(i) Otto-cycle. A catalyst is replaced with a deteriorated or 
defective catalyst, or an electronic simulation of such, resulting in an 
increase of 1.5 times the NMHC standard or FEL above the NMHC emission 
level measured using a representative 4000 mile catalyst system.
    (ii) Diesel. (A) If monitored for emissions performance--a catalyst 
is replaced with a deteriorated or defective catalyst, or an electronic 
simulation of such, resulting in exhaust emissions exceeding 1.5 times 
the applicable standard or FEL for NOX or PM.

detected.
    (3) If so equipped, any oxygen sensor is replaced with a 
deteriorated or defective oxygen sensor, or an electronic simulation of 
such, resulting in exhaust emissions exceeding 1.5 times the applicable 
standard or FEL for NMHC, CO or NOX.
    (4) If so equipped, a vapor leak is introduced in the evaporative 
and/or refueling system (excluding the tubing and connections between 
the purge valve and the intake manifold) greater than or equal in 
magnitude to a leak caused by a 0.040 inch diameter orifice, or the 
evaporative purge air flow is blocked or otherwise eliminated from the 
complete evaporative emission control system.
    (5) A malfunction condition is induced in any emission-related 
powertrain system or component, including but not necessarily limited 
to, the exhaust gas recirculation (EGR) system, if equipped, the 
secondary air system, if equipped, and the fuel control system, 
singularly resulting in exhaust emissions exceeding 1.5 times the 
applicable emission standard or FEL for NMHC, CO, NOX or PM.
    (6) A malfunction condition is induced in an electronic emission-
related powertrain system or component not otherwise described in this 
paragraph (k) that either provides input to or receives commands from 
the on-board computer resulting in a measurable impact on emissions.
    (7) For clean alternative fuel conversion manufacturers (e.g., 
natural gas, liquefied petroleum gas, methanol, ethanol), in lieu of the 
requirements specified for other manufacturers in this paragraph (k), 
you may demonstrate that the malfunction indicator light will 
illuminate, at a minimum, under any of the following circumstances when 
the vehicle is operated on the applicable alternative fuel:
    (i) Otto-cycle. A catalyst is replaced with a defective catalyst 
system where the catalyst brick for the monitored volume has been 
removed (i.e., empty catalyst system) resulting in an increase of 1.5 
times the NMOG (or NMOG + NOX) standard or FEL above the NMOG 
(or NMOG + NOX) emission level measured using a 
representative 4000 mile catalyst system.
    (ii) Diesel. (A) If monitored for emissions performance--a catalyst 
is replaced with a defective catalyst system where the catalyst brick 
for the monitored volume has been removed (i.e., empty catalyst can) 
resulting in exhaust emissions exceeding 1.5 times the applicable 
standard or FEL for NOX (or NMOG + NOX) or PM.
    (B) If monitored for performance--a particulate trap is replaced 
with a trap that has catastrophically failed.
    (iii) Misfire. (A) Otto-cycle. An engine misfire condition is 
induced that completely disables one or more cylinders, either through 
mechanical or electrical means, resulting in exhaust emissions exceeding 
1.5 times the applicable standards or FEL for CO, NMOG, or 
NOX (or NMOG + NOX).
    (B) Diesel. An engine misfire condition resulting in complete lack 
of cylinder firing is induced and is not detected.
    (iv) If so equipped, any oxygen sensor is replaced with a completely

    (v) If so equipped and applicable, a vapor leak is introduced in the 
evaporative and/or refueling system (excluding the tubing and 
connections between the purge valve and the intake manifold) greater 
than or equal in magnitude to a leak caused by a 0.040 inch diameter 
orifice, or the evaporative purge air flow is blocked or otherwise 
eliminated from the complete evaporative emission control system. At a 
minimum, gas cap removal or complete venting of the evaporative and/or 
refueling system may be introduced resulting in a gross leak of the 
complete evaporative emission control system.
    (vi) A malfunction condition is induced resulting in complete 
disablement in any emission-related

[[Page 917]]

powertrain system or component, including but not necessarily limited 
to, the exhaust gas recirculation (EGR) system, if equipped, the 
secondary air system, if equipped, and the fuel control system, 
singularly resulting in exhaust emissions exceeding 1.5 times the 
applicable emission standard or FEL for PM, CO, NMOG, or NOX 
(or NMOG + NOX).
    (vii) A malfunction condition is induced that completely disables an 
electronic emission-related powertrain system or component not otherwise 
described in this paragraph (k) that either provides input to or 
receives commands from the onboard computer resulting in a measurable 
impact on emissions. At a minimum, manufacturers may be required to 
perform this disablement on critical inputs and outputs where lack of 
the input and output disables an entire monitor as described in this 
paragraph (k)(7)(vii), disables multiple monitors (e.g., two or more) 
used by the onboard computer, or renders the entire onboard computer and 
its functions inoperative.
    (viii) Clean alternative fuel conversion manufacturers must use good 
engineering judgment to induce malfunctions and may perform more 
stringent malfunction demonstrations than described in this paragraph 
(k)(7). In addition, the Administrator reserves the right to request a 
clean alternative fuel conversion manufacturer to perform stricter 
demonstration requirements, to the extent feasible, on clean alternative 
fuel conversions.
    (l) Phase-in for complete heavy-duty vehicles. Complete heavy-duty 
vehicles weighing 14,000 pounds GVWR or less that are not Otto-cycle 
MDPVs must meet the OBD requirements of this section according to the 
following phase-in schedule, based on the percentage of projected 
vehicle sales. The 2004 model year requirements in the following phase-
in schedule are applicable only to heavy-duty Otto-cycle vehicles where 
the manufacturer has selected Otto-cycle Option 1 or 2 for alternative 
2003 or 2004 compliance according to Sec.86.004-01(c)(1) or (2). The 
2005 through 2007 requirements in the following phase-in schedule apply 
to all heavy-duty vehicles weighing 14,000 pounds GVWR or less, 
excluding MDPVs. If the manufacturer has selected Otto-cycle Option 3 it 
may exempt 2005 model year complete heavy-duty engines and vehicles 
whose model year commences before July 31, 2004 from the requirements of 
this section. For the purposes of calculating compliance with the phase-
in provisions of this paragraph (l), heavy-duty vehicles subject to the 
phase-in requirements of this section may be combined with heavy-duty 
vehicles subject to the phase-in requirements of paragraph Sec.86.005-
17 (k). The phase-in schedule follows:

------------------------------------------------------------------------

    (m) Thresholds for California OBD II Compliance Option. For the 
purposes of complying with the provisions set forth above in paragraph 
(j), vehicles certified to Tier 2 standards shall utilize multiplicative 
factors from the California vehicle type (i.e. LEV II, ULEV II) 
corresponding to the Tier 2 to which the vehicles are certified. 
Vehicles certified to Tier 2, Bin 4 emissions standards shall utilize 
the Tier 2 Bin 4 emission standards and the CARB ULEV II multiplicative 
factors to determine the appropriate OBD malfunction threshold for all 
pollutants except NOX, for which they shall utilize that CARB 
SULEV II multiplicative factors. Vehicles certified to Tier 2, Bin 3 
emissions standards shall utilize the Tier 2 Bin 3 emission standards 
and the CARB ULEV II multiplicative factors to determine the appropriate 
OBD malfunction threshold for all pollutants except NOX, for 
which they shall utilize that CARB SULEV II multiplicative factors. 
Vehicles certified to Tier 2, Bin 2 emissions standards shall utilize 
the Tier 2 Bin 2 emission standards and the CARB

[[Page 918]]

SULEV II multiplicative factors to determine the appropriate OBD 
malfunction threshold. Vehicles certified to Tier 2 Bin 7 or higher 
shall utilize the CARB LEV II multiplicative factors to determine the 
appropriate OBD malfunction threshold.
    (n) For 2007 and later model year diesel complete heavy-duty 
vehicles, in lieu of the malfunction descriptions of paragraph (b) of 
this section, the malfunction descriptions of this paragraph (n) shall 
apply. The OBD system must detect and identify malfunctions in all 
monitored emission-related powertrain systems or components according to 
the following malfunction definitions as measured and calculated in 
accordance with test procedures set forth in subpart B of this part 
(chassis-based test procedures), excluding those test procedures defined 
as ``Supplemental'' test procedures in Sec.86.004-2 and codified in 
Sec. Sec.86.158, 86.159, and 86.160.
    (1) Catalysts and diesel particulate filters (DPF). (i) If equipped, 
reduction catalyst deterioration or malfunction before it results in 
exhaust emissions exceeding, for model years 2007 through 2009, 4 times 
the applicable NOX standard and, for model years 2010 through 
2012, the applicable NOX standard + 0.6 g/mi and, for model 
years 2013 and later, the applicable NOX standard + 0.3 g/mi. 
Further, if equipped, oxidation catalyst (not to include the DPF), 
deterioration or malfunction before it results in exhaust NMHC emissions 
exceeding, for 2010 through 2012 model years, 2.5 times the applicable 
NMHC standard and, for 2013 and later model years, 2 times the 
applicable NMHC standard. Monitoring of oxidation catalysts is not 
required through the 2009 model year. These catalyst monitoring need not 
be done if the manufacturer can demonstrate that deterioration or 
malfunction of the system will not result in exceedance of the 
threshold. As an alternative to the oxidation catalyst monitoring 
requirement, the monitor can be designed to detect oxidation catalyst 
deterioration or malfunction before it results in an inability to 
achieve a temperature rise of 100 degrees C, or to reach the necessary 
DPF regeneration temperature, within 60 seconds of initiating an active 
DPF regeneration. Further, oxidation catalyst deterioration or 
malfunction when the DOC is unable to sustain the necessary regeneration 
temperature for the duration of the regeneration event. The OBD or 
control system must abort the regeneration if the regeneration 
temperature has not been reached within five minutes of initiating an 
active regeneration event, and if the regeneration temperature cannot be 
sustained for the duration of the regeneration event.
    (ii) If equipped with a DPF, for all model years, catastrophic 
failure of the device must be detected. Any DPF whose complete failure 
results in exhaust emissions exceeding 1.5 times the applicable PM 
standard or family emissions limit (FEL) must be monitored for such 
catastrophic failure. This monitoring need not be done if the 
manufacturer can demonstrate that a catastrophic failure of the system 
will not result in exceedance of the threshold. Further, if equipped 
with a DPF, the OBD system shall detect DPF deterioration or malfunction 
before it results in exhaust emissions exceeding, for 2010 through 2012 
model years, 4 times the applicable PM standard and, for 2013 and later 
model years, the applicable PM standard + 0.04 g/mi.
    (2) Engine misfire. Lack of cylinder combustion must be detected.
    (3) Exhaust gas sensors--(i) Oxygen sensors and air-fuel ratio 
sensors downstream of aftertreatment devices. If equipped, sensor 
deterioration or malfunction resulting in exhaust emissions exceeding 
any of the following levels: for 2007 through 2009 model years, 4 times 
the applicable PM standard, or 3 times the applicable NOX 
standard, or 2.5 times the applicable NMHC standard and, for 2010 
through 2012 model years, 4 times the applicable PM standard, or the 
applicable NOX standard + 0.3 g/mi, or 2.5 times the 
applicable NMHC standard and, for 2013 and later model years, the 
applicable PM standard + 0.04 g/mi, or the applicable NOX 
standard + 0.3 g/mi, or 2 times the applicable NMHC standard.
    (ii) Oxygen sensors and air-fuel ratio sensors upstream of 
aftertreatment devices. If equipped, sensor deterioration or malfunction 
resulting in exhaust emissions exceeding any of the following levels: 
for 2007 through 2009

[[Page 919]]

model years, 4 times the applicable PM standard, or 3 times the 
applicable NOX standard, or 2.5 times the applicable NMHC 
standard, or 2.5 times the applicable CO standard and, for 2010 through 
2012 model years, the applicable PM standard + 0.02 g/mi, or the 
applicable NOX standard + 0.3 g/mi, or 2.5 times the 
applicable NMHC standard, or 2.5 times the applicable CO standard and, 
for 2013 and later model years, the applicable PM standard + 0.02 g/mi, 
or the applicable NOX standard + 0.3 g/mi, or 2 times the 
applicable NMHC standard, or 2 times the applicable CO standard.
    (iii) NOX sensors. If equipped, sensor deterioration or malfunction 
resulting in exhaust emissions exceeding any of the following levels: 
for 2007 through 2009 model years, 5 times the applicable PM standard, 
or 4 times the applicable NOX standard and, for 2010 through 
2012 model years, 4 times the applicable PM standard, or the applicable 
NOX standard + 0.6 g/mi and, for 2013 and later model years, 
the applicable PM standard + 0.04 g/mi, or the applicable NOX 
standard + 0.3 g/mi.
    (4) [Reserved]
    (5) Other emission control systems and components. Any deterioration 
or malfunction occurring in an engine system or component directly 
intended to control emissions, including but not necessarily limited to, 
the exhaust gas recirculation (EGR) system, if equipped, and the fuel 
control system, singularly resulting in exhaust emissions exceeding any 
of the following levels: For 2007 through 2009 model years, 4 times the 
applicable PM standard, or 3 times the applicable NOX 
standard, or 2.5 times the applicable NMHC standard, or 2.5 times the 
applicable CO standard and, for 2010 through 2012 model years, 4 times 
the applicable PM standard, or the applicable NOX standard + 
0.3 g/mi, or 2.5 times the applicable NMHC standard, or 2.5 times the 
applicable CO standard and, for 2013 and later model years, the 
applicable PM standard + 0.02 g/mi, or the applicable NOX 
standard + 0.3 g/mi, or 2 times the applicable NMHC standard, or 2 times 
the applicable CO standard. A functional check, as described in 
paragraph (n)(6) of this section, may satisfy the requirements of this 
paragraph (n)(5) provided the manufacturer can demonstrate that a 
malfunction would not cause emissions to exceed the applicable levels. 
This demonstration is subject to Administrator approval. For engines 
equipped with crankcase ventilation (CV), monitoring of the CV system is 
not necessary provided the manufacturer can demonstrate to the 
Administrator's satisfaction that the CV system is unlikely to fail.
    (6) Other emission-related powertrain components. Any other 
deterioration or malfunction occurring in an electronic emission-related 
powertrain system or component not otherwise described in paragraphs 
(n)(1) through (n)(5) of this section that either provides input to or 
receives commands from the on-board computer and has a measurable impact 
on emissions; monitoring of components required by this paragraph (n)(6) 
must be satisfied by employing electrical circuit continuity checks and 
rationality checks for computer input components (input values within 
manufacturer specified ranges based on other available operating 
parameters), and functionality checks for computer output components 
(proper functional response to computer commands) except that the 
Administrator may waive such a rationality or functionality check where 
the manufacturer has demonstrated infeasibility. Malfunctions are 
defined as a failure of the system or component to meet the electrical 
circuit continuity checks or the rationality or functionality checks.
    (7) Performance of OBD functions. Any sensor or other component 
deterioration or malfunction which renders that sensor or component 
incapable of performing its function as part of the OBD system must be 
detected and identified on engines so equipped.
    (o) For 2007 and later model year diesel complete heavy-duty 
vehicles, in lieu of the certification provisions of paragraph (k) of 
this section, the certification provisions of this paragraph (o) shall 
apply. For test groups required to have an OBD system, certification 
will not be granted if, for any test vehicle approved by the 
Administrator in consultation with the manufacturer, the malfunction 
indicator light does not illuminate under any of the following 
circumstances, unless the manufacturer can demonstrate that

[[Page 920]]

any identified OBD problems discovered during the Administrator's 
evaluation will be corrected on production vehicles.
    (1)(i) If monitored for emissions performance--a reduction catalyst 
is replaced with a deteriorated or defective catalyst, or an electronic 
simulation of such, resulting in exhaust emissions exceeding, for 2007 
through 2009 model years, 4 times the applicable NOX standard 
and, for 2010 through 2012 model years, the applicable NOX 
standard + 0.6 g/mi and, for 2013 and later model years, the applicable 
NOX standard + 0.3 g/mi. Also if monitored for emissions 
performance-an oxidation catalyst (not to include the DPF) is replaced 
with a deteriorated or defective catalyst, or an electronic simulation 
of such, resulting in exhaust NMHC emissions exceeding, for 2010 through 
2012 model years, 2.5 times the applicable NMHC standard and, for 2013 
and later model years, 2 times the applicable NMHC standard. If 
monitored for exotherm performance for 2010 and later model years, an 
oxidation catalsyt is replaced with a deteriorated or defective 
catalyst, or an electronic simulation of such, resulting in an inability 
to achieve a 100 degree C temperature rise, or the necessary 
regeneration temperature, within 60 seconds of initiating a DPF 
regeneration.
    (ii) If monitored for performance--a DPF is replaced with a DPF that 
has catastrophically failed, or an electronic simulation of such. 
Further, a DPF is replaced with a deteriorated or defective DPF, or an 
electronic simulation of such, resulting in exhaust PM emissions 
exceeding, for 2010 through 2012 model years, 4 times the applicable PM 
standard and, for 2013 and later model years, the applicable PM standard 
+ 0.04 g/mi.
    (2) An engine misfire condition is induced and is not detected.
    (3)(i) If so equipped, any oxygen sensor or air-fuel ratio sensor 
located downstream of aftertreatment devices is replaced with a 
deteriorated or defective sensor, or an electronic simulation of such, 
resulting in exhaust emissions exceeding any of the following levels: 
for 2007 through 2009 model years, 4 times the applicable PM standard, 
or 3 times the applicable NOX standard, or 2.5 times the 
applicable NMHC standard and, for 2010 through 2012 model years, 4 times 
the applicable PM standard, or the applicable NOX standard + 
0.3 g/mi, or 2.5 times the applicable NMHC standard and, for 2013 and 
later model years, the applicable PM standard + 0.04 g/mi, or the 
applicable NOX standard + 0.3 g/mi, or 2 times the applicable 
NMHC standard.
    (ii) If so equipped, any oxygen sensor or air-fuel ratio sensor 
located upstream of aftertreatment devices is replaced with a 
deteriorated or defective sensor, or an electronic simulation of such, 
resulting in exhaust emissions exceeding any of the following levels: 
for 2007 through 2009 model years, 4 times the applicable PM standard, 
or 3 times the applicable NOX standard, or 2.5 times the 
applicable NMHC standard, or 2.5 times the applicable CO standard and, 
for 2010 through 2012 model years, the applicable PM standard + 0.02 g/
mi, or the applicable NOX standard + 0.3 g/mi, or 2.5 times 
the applicable NMHC standard, or 2.5 times the applicable CO standard 
and, for 2013 and later model years, the applicable PM standard + 0.02 
g/mi, or the applicable NOX standard + 0.3 g/mi, or 2 times 
the applicable NMHC standard, or 2 times the applicable CO standard.
    (iii) If so equipped, any NOX sensor is replaced with a 
deteriorated or defective sensor, or an electronic simulation of such, 
resulting in exhaust emissions exceeding any of the following levels:

Sec.86.1806-17  Onboard diagnostics.

    Model year 2017 and later vehicles must have onboard diagnostic 
(OBD) systems as described in this section. OBD systems must generally 
detect malfunctions in the emission control system, store trouble codes 
corresponding to detected malfunctions, and alert operators 
appropriately.
    (a) Vehicles must comply with the 2013 OBD requirements adopted for 
California as described in this paragraph (a). California's 2013 OBD-II 
requirements are part of Title 13, Sec.1968.2 of the California Code 
of Regulations, approved on July 31, 2013 (incorporated by reference in 
Sec.86.1). The following clarifications and exceptions apply for 
vehicles certified under this subpart:
    (1) For vehicles not certified in California, references to vehicles 
meeting certain California Air Resources Board emission standards are 
understood to refer to the corresponding EPA emission standards for a 
given family, where applicable. Use good engineering judgment to 
correlate the specified standards with the bin standards that apply 
under this subpart.
    (2) Vehicles must comply with OBD requirements throughout the useful 
life as specified in Sec.86.1805. If the specified useful life is 
different for evaporative and exhaust emissions, the useful life 
specified for evaporative emissions applies for monitoring related to 
fuel-system leaks and the useful life specified for exhaust emissions 
applies for all other parameters.
    (3) The purpose and applicability statements in 13 CCR 1968.2(a) and 
(b) do not apply.
    (4) The anti-tampering provisions in 13 CCR 1968.2(d)(1.4) do not 
apply.
    (5) The requirement to verify proper alignment between the camshaft 
and crankshaft described in 13 CCR 1968.2(e)(15.2.1)(C) applies only for 
vehicles equipped with variable valve timing.
    (6) The deficiency provisions described in paragraph (c) of this 
section apply instead of 13 CCR 1968.2(k).
    (7) For emergency vehicles only, the provisions of 13 CCR 
1968.2(e)(6.2.1) related to monitoring and identification of air-fuel 
ratio cylinder imbalance, as part of the fuel system monitoring, do not 
apply until model year 2020, unless the vehicle met the requirements in 
2016 or earlier model years.
    (8) Apply thresholds for exhaust emission malfunctions from Tier 3 
vehicles based on the thresholds calculated for the corresponding bin 
standards in the California LEV II program as prescribed for the latest 
model year in 13 CCR 1968.2(e) and (f). For example, for Tier 3 Bin 160 
standards, apply the threshold that applies for the LEV standards. For 
cases involving Tier 3 standards that have no corresponding bin 
standards from the California LEV II program, use the next highest LEV 
II bin. For example, for Tier 3 Bin 50 standards, apply the threshold 
that applies for the ULEV standards. You may apply thresholds that are 
more stringent than we require under this paragraph (a)(8).
    (b) The following additional provisions apply:
    (1) Model year 2017 and later vehicles must meet the OBD system 
requirements described in this paragraph (b)(1). When monitoring 
conditions are satisfied, test vehicles must detect the presence of a 
leak with an effective leak diameter at or above 0.020 inches,

[[Page 922]]

illuminate the MIL, and store the appropriate confirmed diagnostic 
trouble codes (DTCs) (13 CCR 1968.2 refers to these as fault codes). For 
a 0.020 inch leak, the DTC(s) shall be a generic SAE J2012 DTC that is 
specific to an EVAP system very small leak (e.g., P0456, P04EE, or 
P04EF) or an equivalent manufacturer-specific DTC that we approve. 
Conduct testing using an O'Keefe Controls Co. metal ``Type B'' orifice 
with a diameter of 0.020 inches or an alternate orifice diameter 
approved under 13 CCR 1968.2(e)(4.2.3) or (e)(4.2.4).
    (i) Use the methodology specified in 13 CCR 1968.2(h)(2.2) to select 
test vehicles to demonstrate that the OBD system is capable of detecting 
a 0.020 inch leak installed in the evaporative system, except that the 
manufacturer may use production-representative vehicles instead of the 
vehicle options specified in 13 CCR 1968.2(h)(2.3).
    (ii) Perform tests in the laboratory, with or without a dynamometer, 
or on an outdoor road surface, as necessary to exercise the vehicle's 
ability to detect leaks in the evaporative system.
    (iii) Perform at least two tests to evaluate the OBD system for 
leaks that are installed near the fuel fill pipe and near the canister. 
The implanted leak near the fuel fill pipe must be at the fuel cap or 
between the fuel cap and the fuel tank. The implanted leak near the 
canister must be in the vapor line between the canister and the fuel 
tank, or between the canister and the purge valve). If a vehicle has 
multiple canisters or fuel fill pipes, repeat the testing to evaluate 
the system for implanted leaks corresponding to each canister and fuel 
fill pipe. You may propose to implant leaks in different locations 
(e.g., near the purge valve); we will approve your alternate leak 
location if it more effectively demonstrates leak detection for your 
particular fuel system design.
    (iv) If vehicle operation is needed to fulfill preconditioning 
(i.e., when engine-off tests require driving before vehicle shutdown to 
enable the engine-off monitor) or monitoring conditions for leak 
detection under this paragraph (b)(1) utilize an FTP cycle, Unified 
cycle, or some other specified operating cycle that will satisfy the 
approved monitoring or preconditioning conditions without the 
interference of approved deficiencies. Continue vehicle operation as 
needed to illuminate the MIL and store the appropriate DTCs.
    (v) Emission measurements are not required during this OBD 
evaporative system leak monitoring demonstration testing.
    (vi) For test groups not selected for testing in a given model year, 
you may instead provide a statement in the application for 
certification, consistent with good engineering judgment, that vehicles 
meet leak-detection requirements based on previous OBD tests, 
development tests, or other appropriate information. For any untested 
test groups, the statement specified in Sec.86.1844-01(d)(8) applies 
with regard to the leak monitoring requirement. We may ask you to 
provide the data and other information that formed the basis for your 
statement. Select test groups in later model years such that testing 
will rotate to cover your whole product line over time.
    (vii) Submit the following information in the application for 
certification:
    (A) Describe the test sequence.
    (B) Identify the driving cycle used and the time expired and 
distance driven before the MIL illuminated.
    (C) Identify the ranges of in-use environmental and vehicle 
operating conditions for which the vehicle will not meet the leak-
detection specifications described in this paragraph (b)(1). To meet 
this requirement, you may give us the same information you gave the 
California Air Resources Board regarding enable conditions for the 
evaporative system leak monitor.
    (D) Identify the confirmed and permanent DTCs set by the OBD system 
during testing.
    (E) Include the freeze frame information stored at the point the 
fault is detected.
    (F) Include the SAE J1979 test results (e.g., Mode/Service $06) 
corresponding to the DTCs that were stored during the test.
    (viii) If you have one or more vehicle models in model year 2016 
that do not comply with the leak requirements in 13 CCR 1968.2(e)(4), 
you may comply

[[Page 923]]

with the requirements of this paragraph (b)(1) in model year 2017 by 
substituting model year 2016 vehicles on an equal-percentage basis. 
Demonstrate this by calculating the percentage of vehicles subject to 
OBD requirements under this subpart that meet the requirements of this 
paragraph (b)(1) in model years 2016 and 2017; the sum of these two 
percentage values must be at or above 100 percent. Any model year 2017 
vehicles not meeting the requirements of this paragraph (b)(1), as 
allowed by this paragraph (b)(1)(viii), may not be counted as compliant 
Tier 3 vehicles under the alternative phase-in specified in Sec.
86.1813-17(g)(2)(ii).
    (2) For vehicles subject to the leak standard in Sec.86.1813, OBD 
systems must record in computer memory the result of the most recent 
successfully completed diagnostic check for a 0.020 inch leak. Someone 
must be able to use the data to determine the miles driven since the 
last check occurred, the pass/fail result, and whether there has been a 
check since the computer memory was last cleared (e.g., from a scan tool 
command or battery disconnect). The system may be designed to keep data 
only from the previous 750 miles of driving. (Note: This 750 mile 
requirement is related to the use of the OBD evaporative leak monitor in 
the leak test and should not be confused with either the minimum or 
maximum distance values specified in Table G-19 of SAE J1979.) The data 
must be reported in a standardized format consistent with other data 
required for the OBD system. The results must be scan-readable.
    (3) For vehicles with fuel tanks exceeding 25 gallons nominal fuel 
tank capacity, you may request our approval for a leak threshold greater 
than 0.020 inches, up to a maximum value of 0.040 inches. We will 
generally approve a leak threshold equal to the standard that applies 
under Sec.86.1813.
    (c) You may ask us to accept as compliant a vehicle that does not 
fully meet specific requirements under this section. Such deficiencies 
are intended to allow for minor deviations from OBD standards under 
limited conditions. We expect vehicles to have functioning OBD systems 
that meet the objectives stated in this section. The following 
provisions apply regarding OBD system deficiencies:
    (1) Except as specified in paragraph (d) of this section, we will 
not approve a deficiency that involves the complete lack of a major 
diagnostic monitor, such as monitors related to exhaust aftertreatment 
devices, oxygen sensors, air-fuel ratio sensors, NOX sensors, 
engine misfire, evaporative leaks, and diesel EGR (if applicable).
    (2) We will approve a deficiency only if you show us that full 
compliance is infeasible or unreasonable considering any relevant 
factors, such as the technical feasibility of a given monitor, or the 
lead time and production cycles of vehicle designs and programmed 
computing upgrades.
    (3) Our approval for a given deficiency applies only for a single 
model year, though you may continue to ask us to extend a deficiency 
approval in renewable one-year increments. We may approve an extension 
if you demonstrate an acceptable level of effort toward compliance and 
show that the necessary hardware or software modifications would pose an 
unreasonable burden.
    (d) For alternative-fuel vehicles, manufacturers may request a 
waiver from specific requirements for which monitoring may not be 
reliable for operation with the alternative fuel. However, we will not 
waive requirements that we judge to be feasible for a particular 
manufacturer or vehicle model.
    (e) For alternative-fuel conversions, manufacturers may meet the 
requirements of Sec.86.1806-05 instead of the requirements of this 
section.
    (f) You may ask us to waive certain requirements in this section for 
emergency vehicles. We will approve your request for an appropriate 
duration if we determine that the OBD requirement in question could harm 
system performance in a way that would impair a vehicle's ability to 
perform its emergency functions.
    (g) The following interim provisions describe an alternate 
implementation schedule for the requirements of this section in certain 
circumstances:
    (1) Manufacturers may delay complying with all the requirements of 
this

[[Page 924]]

section, and instead meet all the requirements that apply under Sec.
86.1806-05, for any heavy-duty vehicles that are not yet subject to the 
Tier 3 standards in Sec.86.1816.
    (2) Except as specified in this paragraph (g)(2), small-volume 
manufacturers may delay complying with all the requirements of this 
section until model year 2022, and instead meet all the requirements 
that apply under Sec.86.1806-05 during those years. This provision 
does not apply for a vehicle model if it is identical to a 2016 vehicle 
model that was certified to meet California's OBD requirements under 
Sec.86.1806-05(j)(3). A vehicle model is considered identical to one 
from model year 2016 if it is certified in the current year based on the 
same test data for exhaust or evaporative emissions under the carryover 
data provisions of this subpart.
    (3) Manufacturers may disregard the requirements of this section 
that apply above 8,500 pounds GVWR before model year 2019 and instead 
meet all the requirements that apply under Sec.86.1806-05. This also 
applies for model year 2019 vehicles from a test group with vehicles 
that have a Job 1 date on or before March 3, 2018 (see 40 CFR 85.2304).

Sec.86.1808-01  Maintenance instructions.

    (a) The manufacturer shall furnish or cause to be furnished to the 
purchaser of each new motor vehicle subject to

[[Page 926]]

the standards prescribed in this subpart, as applicable, written 
instructions for the proper maintenance and use of the vehicle, by the 
purchaser consistent with the provisions of Sec.86.1834-01, which 
establishes what scheduled maintenance the Administrator approves as 
being reasonable and necessary.
    (1) The maintenance instructions required by this section shall be 
in clear, and to the extent practicable, nontechnical language.
    (2) The maintenance instructions required by this section shall 
contain a general description of the documentation which the 
manufacturer will require from the ultimate purchaser or any subsequent 
purchaser as evidence of compliance with the instructions.
    (b) Instructions provided to purchasers under paragraph (a) of this 
section shall specify the performance of all scheduled maintenance 
performed by the manufacturer on certification durability vehicles and, 
in cases where the manufacturer performs less maintenance on 
certification durability data vehicles than the allowed limit, may 
specify the performance of any scheduled maintenance allowed under Sec.
86.1834-01.
    (c) Scheduled emission-related maintenance in addition to that 
performed under Sec.86.1834-01 may only be recommended to offset the 
effects of abnormal in-use operating conditions, except as provided in 
paragraph (d) of this section. The manufacturer shall be required to 
demonstrate, subject to the approval of the Administrator, that such 
maintenance is reasonable and technologically necessary to assure the 
proper functioning of the emission control system. Such additional 
recommended maintenance shall be clearly differentiated, in a form 
approved by the Administrator, from that approved under Sec.86.1834-
01.
    (d) Inspections of emission-related parts or systems with 
instructions to replace, repair, clean, or adjust the parts or systems 
if necessary, are not considered to be items of scheduled maintenance 
which insure the proper functioning of the emission control system. Such 
inspections, and any recommended maintenance beyond that approved by the 
Administrator as reasonable and necessary under paragraphs (a), (b), and 
(c) of this section, may be included in the written instructions 
furnished to vehicle owners under paragraph (a) of this section, 
provided that such instructions clearly state, in a form approved by the 
Administrator, that the owner need not perform such inspections or 
recommended maintenance in order to maintain the emission warranty or 
manufacturer recall liability.
    (e) If the vehicle has been granted an alternative useful life 
period under the provisions of Sec.86.1805-01(c), the manufacturer may 
choose to include in such instructions an explanation of the distinction 
between the alternative useful life specified on the label, and the 
emissions defect and emissions performance warranty period. The 
explanation must clearly state that the useful life period specified on 
the label represents the average period of use up to retirement or 
rebuild for the test group represented by the engine used in the 
vehicle. An explanation of how the actual useful lives of engines used 
in various applications are expected to differ from the average useful 
life may be included. The explanation(s) shall be in clear, non-
technical language that is understandable to the ultimate purchaser.
    (f) Emission control diagnostic service information:
    (1) Applicability. Manufacturers are subject to the provisions of 
this paragraph (f) for 1996 model year for and later light-duty vehicles 
and light-duty trucks. Manufacturers are subject to the provisions of 
this paragraph (f) for 2005 model year and later heavy-duty vehicles at 
or below 14,000 pounds GVWR and the corresponding engines that are 
subject to the OBD requirements of this part.
    (2) General requirements. (i) Manufacturers shall furnish or cause 
to be furnished to any person engaged in the repairing or servicing of 
motor vehicles or motor vehicle engines, or the Administrator upon 
request, any and all information needed to make use of the on-board 
diagnostic system and such other information, including instructions for 
making emission-related diagnoses and repairs, including but not limited 
to service manuals, technical

[[Page 927]]

service bulletins, recall service information, bi-directional control 
information, and training information, unless such information is 
protected by section 208(c) of the Act as a trade secret. No such 
information may be withheld under section 208(c) of the Act if that 
information is provided (directly or indirectly) by the manufacturer to 
franchised dealers or other persons engaged in the repair, diagnosing, 
or servicing of motor vehicles or motor vehicle engines.
    (ii) Definitions. The following definitions apply for this paragraph 
(f):
    (A) Aftermarket service provider means any individual or business 
engaged in the diagnosis, service, and repair of a motor vehicle or 
engine, who is not directly affiliated with a manufacturer or 
manufacturer-franchised dealership.
    (B) Bi-directional control means the capability of a diagnostic tool 
to send messages on the data bus that temporarily overrides the module's 
control over a sensor or actuator and gives control to the diagnostic 
tool operator. Bi-directional controls do not create permanent changes 
to engine or component calibrations.
    (C) Data stream information means information (i.e., messages and 
parameters) originated within the vehicle by a module or intelligent 
sensors (i.e., a sensor that contains and is controlled by its own 
module) and transmitted between a network of modules and/or intelligent 
sensors connected in parallel with either one or more communication 
wires. The information is broadcast over the communication wires for use 
by the OBD system to gather information on emissions-related components 
or systems and from other vehicle modules that may impact emissions, 
including but not limited to systems such as chassis or transmission. 
For the purposes of this section, data stream information does not 
include engine calibration related information, or any data stream 
information from systems or modules that do not impact emissions.
    (D) Emissions-related information means any information related to 
the diagnosis, service, and repair of emissions-related components. 
Emissions-related information includes, but is not limited to, 
information regarding any system, component or part of a vehicle that 
controls emissions and any system, component and/or part associated with 
the powertrain system, including, but not limited to:
    (1) The engine, the fuel system and ignition system;
    (2) Information for any system, component or part that is likely to 
impact emissions, such as transmission systems, and any other 
information specified by the Administrator to be relevant to the 
diagnosis and repair of an emissions-related problem; and
    (3) Any other information specified by the Administrator to be 
relevant for the diagnosis and repair of an emissions-related failure 
found through the inspection and maintenance program after such finding 
has been communicated to the affected manufacturer(s).
    (E) Emissions-related training information means any information 
related to training or instruction for the purpose of the diagnosis, 
service, and repair of emissions-related components.
    (F) Enhanced service and repair information means information which 
is specific for an original equipment manufacturer's brand of tools and

other emission-related part shall be made available at a fair and 
reasonable cost to the persons specified in paragraph (f)(2)(i) of this 
section.
    (i) Except as provided under paragraph (f)(6)(ii) of this section, 
manufacturers must make this information available to persons specified 
in paragraph (f)(2)(i) of this section, such that such persons will not 
need any special tools or manufacturer-specific scan tools to perform 
the initialization. Manufacturers may make such information available 
through, for example, generic aftermarket tools, a pass-through device, 
or inexpensive manufacturer specific cables.
    (ii) A manufacturer may request Administrator approval for an 
alternative means to re-initialize vehicles for some or all model year

date of the final rule. The Administrator shall approve the request only 
after the following conditions have been met:
    (A) The manufacturer must demonstrate that the availability of such 
information to aftermarket service providers would significantly 
increase the risk of vehicle theft.
    (B) The manufacturer must make available a reasonable alternative 
means to install or repair computers, or to otherwise repair or replace 
an emission-related part.
    (C) Any alternative means proposed by a manufacturer cannot require 
aftermarket technicians to use a manufacturer-franchised dealership to 
obtain information or special tools to re-initialize the anti-theft 
system. All information must come directly from the manufacturer or a 
single manufacturer-specified designee.
    (D) Any alternative means proposed by a manufacturer must be 
available to aftermarket technicians at a fair and reasonable price.
    (E) Any alternative must be available to aftermarket technicians 
within twenty-four hours of the initial request.
    (F) Any alternative must not require the purchase of a special tool 
or tools, including manufacturer-specific tools, to complete this

Administrator a request for approval of their pricing structure for 
their Web sites and amounts to be charged for the information required 
to be made available under paragraphs (f)(3) and (f)(5) of this section. 
Subsequent to the approval of the manufacturer Web site pricing 
structure, each manufacturer shall notify the Administrator upon the 
increase in price of any one or all of the subscription options of 20 
percent or more above the previously approved price, taking inflation 
into account.
    (A) The manufacturer shall submit a request to the Administrator 
that sets forth a detailed description of the pricing structure and 
amounts, and support for the position that the pricing structure and 
amounts are fair and reasonable by addressing, at a minimum, each of the 
factors specified in paragraph (f)(7)(i) of this section.
    (B) The Administrator will act on the request within 180 days 
following receipt of a complete request or following receipt of any 
additional information requested by the Administrator.

within 3 months of model introduction for all new model years.
    (iii) For all 2004 and later OBD vehicles equipped with 
reprogramming capability, manufacturers shall comply with SAE J2534 
(Incorporated by reference, see Sec.86.1). Any manufacturer who cannot 
comply with SAE J2534 in model year 2004 may request one year additional 
lead time from the Administrator.
    (iv) For model years 2004 and later, manufacturers shall make 
available to aftermarket service providers the necessary manufacturer-
specific software applications and calibrations needed to initiate pass-
through reprogramming. This software shall be able to run on a standard 
personal computer that utilizes standard operating systems as specified 
in SAE J2534 (Incorporated by reference, see Sec.86.1).
    (v) For model years prior to 2004, manufacturers may use SAE J2534 
as described above, provided they make available to the aftermarket any 
additional required hardware (i.e., cables). Manufacturers may not 
require the purchase or use of a manufacturer-specific scan tool to 
receive or use this additional hardware. Manufacturers must also make 
available the necessary manufacturer-specific software applications and 
calibrations needed to initiate pass-through reprogramming. 
Manufacturers must also make available to equipment and tool companies 
any information needed to develop aftermarket equivalents of the 
manufacturer-specific hardware.
    (vi) Manufacturers may take any reasonable business precautions 
necessary to protect proprietary business information and are not 
required to provide this information to any party that does not agree to 
these reasonable business precautions. The requirement to make hardware 
available and to release the information to equipment and tool companies 
takes effect on September 25, 2003, and within 3 months of model 
introduction for all new model years.
    (vii) Manufacturers who cannot comply with paragraphs (f)(12)(v) and 
(f)(12)(vi) of this section shall make available to equipment and tool 
companies by September 25, 2003 the following information necessary for

    (viii) A manufacturer can propose an alternative to the requirements 
of paragraph (f)(12)(vii) of this section for how aftermarket service 
providers can reprogram an ECU. The Administrator will approve this 
alternative if the manufacturer demonstrates all of the following:
    (A) That it cannot comply with paragraph (f)(12)(v) of this section 
for the vehicles subject to the alternative plan;
    (B) That a very small percentage of its vehicles in model years 
prior to 2004 cannot be reprogrammed with the provisions described in 
paragraph (f)(12)(v) of this section, or that releasing the information 
to tool companies would likely not result in this information being 
incorporated into aftermarket tools; and
    (C) That aftermarket service providers will be able to reprogram 
promptly at a reasonable cost.
    (ix) In meeting the requirements of paragraphs (f)(12)(v) through 
(f)(12)(vii) of this section, manufacturers may take any reasonable 
business precautions necessary to protect proprietary business 
information and are not required to provide this information to any 
party that does not agree to these reasonable business precautions.

section shall be provided electronically using common document formats 
to equipment and tool companies with whom they have appropriate 
licensing, contractual, and/or confidentiality arrangements. To the 
extent that a central repository for this information (e.g. the TEK-NET 
library developed by the Equipment and Tool Institute) is used to 
warehouse this information, the Administrator shall have free 
unrestricted access. In addition, information required by paragraph 
(f)(13) of this section shall be made available to equipment and tool 
companies who are not otherwise members of any central repository and 
shall have access if the non-members have arranged for the appropriate 
licensing, contractual and/or confidentiality arrangements with the 
manufacturer and/or a central repository.
    (ii) In addition to the generic and enhanced information defined in 
paragraph (f)(2)(ii) of this section, manufacturers shall also make 
available the following information necessary for developing generic

in paragraph (f)(2)(i) of this section shall adjust the cost of the tool 
accordingly lower to reflect the decreased value of the scan tool. All 
emissions-related content that remains in the manufacturer-specific tool 
shall be identical to the information that is contained in the complete 
version of the manufacturer specific tool. Any manufacturer who wishes 
to implement this option must request approval from the Administrator 
prior to the introduction of the tool into commerce.
    (16) Special tools. (i) Manufacturers who have developed special 
tools to extinguish the malfunction indicator light (MIL) for Model 
Years 1994 through 2003 shall make available the necessary information 
to equipment and tool companies to design a comparable generic tool.
    (ii) Manufacturers are prohibited from requiring special tools to

Sec.86.1809-01  Prohibition of defeat devices.

    (a) No new light-duty vehicle, light-duty truck, or complete heavy-
duty vehicle shall be equipped with a defeat device.
    (b) The Administrator may test or require testing on any vehicle at 
a designated location, using driving cycles and conditions which may 
reasonably be expected to be encountered in normal operation and use, 
for the purposes of investigating a potential defeat device.
    (c) For cold temperature CO emission control, the Administrator will 
use a guideline to determine the appropriateness of the CO emission 
control at ambient temperatures between 25 deg. F (-4 deg. C) and 68 
deg. F (20 deg. C). The guideline for CO emission congruity across the 
intermediate temperature range is the linear interpolation between the 
CO standard applicable at 25 deg. F (-4 deg. C) and the CO standard 
applicable at 68 deg. F (20 deg. C). For vehicles that exceed this CO 
emissions guideline upon intermediate temperature cold testing:
    (1) If the CO emission level is greater than the 20 deg. F (-7 deg. 
C) emission standard, the vehicle will automatically be considered to be 
equipped with a defeat device without further investigation.
    (2) If the CO emission level does not exceed the 20 deg. F emission 
standard, the Administrator may investigate the vehicle design for the 
presence of a defeat device under paragraph (d) of this section.
    (d) For vehicle designs designated by the Administrator to be 
investigated for possible defeat devices:
    (1) The manufacturer must show to the satisfaction of the 
Administrator that the vehicle design does not incorporate strategies 
that unnecessarily reduce emission control effectiveness exhibited 
during the Federal or Supplemental Federal emissions test procedures 
(FTP or SFTP) when the vehicle is operated under conditions which may 
reasonably be expected to be encountered in normal operation and use.
    (2) Information requirements:
    (i) Upon request by the Administrator, the manufacturer will provide 
an explanation containing detailed information regarding test programs, 
engineering evaluations, design specifications, calibrations, on-board 
computer algorithms, and design strategies incorporated for operation 
both during and outside of the Federal emission test procedure.
    (ii) For purposes of investigations of possible cold temperature CO 
defeat devices under this paragraph (d), the manufacturer shall provide 
an explanation which must show, to the satisfaction of the 
Administrator, that CO emissions are reasonably controlled in reference 
to the linear guideline, across the intermediate temperature range.
    (e) For each test group of Tier 2 LDV/LLDTs and HLDT/MDPVs and 
interim non-Tier 2 LDV/LLDTs and HLDT/MDPVs the manufacturer must 
submit, with the Part II certification application, an engineering 
evaluation demonstrating to the satisfaction of the Administrator that a 
discontinuity in emissions of non-methane organic gases, carbon 
monoxide, oxides of nitrogen and formaldehyde measured on the Federal 
Test Procedure (subpart B of this part) does not occur in the 
temperature range of 20 to 86 degrees F. For diesel vehicles, the 
engineering evaluation must also include particulate emissions.

Sec.86.1809-10  Prohibition of defeat devices.

    (a) No new light-duty vehicle, light-duty truck, medium-duty 
passenger vehicle, or complete heavy-duty vehicle shall be equipped with 
a defeat device.
    (b) The Administrator may test or require testing on any vehicle at 
a designated location, using driving cycles and conditions that may 
reasonably be expected to be encountered in normal operation and use, 
for the purposes of investigating a potential defeat device.
    (c) For cold temperature CO and cold temperature NMHC emission 
control, the Administrator will use a guideline to determine the 
appropriateness of the CO and NMHC emission control at ambient 
temperatures between 25 [deg]F (the upper bound of the temperatue test 
range) and 68 [deg]F (the lower bound of the FTP range). The guideline 
for CO emission congruity across the intermediate temperature range is 
the linear interpolation between the CO standard applicable at 25 [deg]F 
and the CO standard applicable at 68 [deg]F. The guideline for NMHC 
emission congruity across the intermediate temperature range is the 
linear interpolation between the NMHC FEL pass limit (e.g. 0.3499 g/mi 
for a 0.3 g/mi FEL) applicable at 20 [deg]F and the Tier 2 NMOG standard 
to which the vehicle was certified at 68 [deg]F, where the intermediate 
temperature NMHC level is rounded to the nearest hundredth for 
comparison to the interpolated line. For vehicles that exceed this CO 
emissions guideline or this NMHC emissions guideline upon intermediate 
temperature cold testing:
    (1) If the CO emission level is greater than the 20 [deg]F emission 
standard, the vehicle will automatically be considered to be equipped 
with a defeat device without further investigation. If the intermediate 
temperature NMHC emission level, rounded to the nearest hundredth, is 
greater than the 20 [deg]F FEL pass limit, the vehicle will be presumed 
to have a defeat device unless the manufacturer provides evidence to 
EPA's satisfaction that the cause of the test result in question is not 
due to a defeat device.
    (2) If the CO emission level does not exceed the 20 [deg]F emission 
standard, the Administrator may investigate the vehicle design for the 
presence of a defeat device under paragraph (d) of this section. If the 
intermediate temperature NMHC emission level, rounded to the nearest 
hundredth, does not exceed the 20 [deg]F FEL pass limit the 
Administrator may investigate the vehicle design for the presence of a 
defeat device under paragraph (d) of this section.
    (d) The following provisions apply for vehicle designs designated by 
the Administrator to be investigated for possible defeat devices:
    (1) The manufacturer must show to the satisfaction of the 
Administrator that the vehicle design does not incorporate strategies 
that unnecessarily reduce emission control effectiveness exhibited 
during the Federal Test Procedure or Supplemental Federal Test Procedure 
(FTP or SFTP) when the vehicle is operated under conditions that may 
reasonably be expected to be encountered in normal operation and use.
    (2) The following information requirements apply:
    (i) Upon request by the Administrator, the manufacturer must provide 
an explanation containing detailed information regarding test programs, 
engineering evaluations, design specifications, calibrations, on-board 
computer algorithms, and design strategies incorporated for operation 
both during and outside of the Federal emission test procedure.
    (ii) For purposes of investigations of possible cold temperature CO 
or cold temperature NMHC defeat devices under this paragraph (d), the 
manufacturer must provide an explanation to show, to the satisfaction of 
the Administrator, that CO emissions and NMHC emissions are reasonably 
controlled in reference to the linear guideline across the intermediate 
temperature range.
    (e) For each test group of Tier 2 LDV/LLDTs and HLDT/MDPVs and 
interim non-Tier 2 LDV/LLDTs and HLDT/MDPVs the manufacturer must 
submit, with the Part II certification application, an engineering 
evaluation demonstrating to the satisfaction of the Administrator that a 
discontinuity in emissions of non-methane organic gases, carbon 
monoxide, oxides of nitrogen and formaldehyde measured on the Federal 
Test Procedure (subpart B of this part) does not occur in the 
temperature range of 20 to 86 [deg]F. For diesel

control, the Administrator will use a guideline to determine the 
appropriateness of the CO and NMHC emission control at ambient 
temperatures between 25 [deg]F (the upper bound of the FTP test 
temperature range) and 68 [deg]F (the lower bound of the FTP test 
temperature range). The guideline for CO emission congruity across the 
intermediate temperature range is the linear interpolation between the 
CO standard applicable at 25 [deg]F and the CO standard applicable at 68 
[deg]F. The guideline for NMHC emission congruity across the 
intermediate temperature range is the linear interpolation between the 
NMHC FEL pass limit (e.g., 0.3499 g/mi for a 0.3 g/mi FEL) applicable at 
20 [deg]F and the Tier 2 NMOG standard or the Tier 3 NMOG + 
NOX bin standard to which the vehicle was certified at 68 
[deg]F, where the intermediate temperature NMHC level is rounded to the 
nearest hundredth for comparison to the interpolated line. For vehicles 
that exceed this CO emissions guideline or this NMHC emissions guideline 
upon intermediate temperature testing:
    (1) If the CO emission level is greater than the 20 [deg]F emission 
standard, the vehicle will automatically be considered to be equipped 
with a defeat device without further investigation. If the intermediate

Administrator may investigate the vehicle design for the presence of a 
defeat device under paragraph (d) of this section.
    (d) The following provisions apply for vehicle designs designated by 
the Administrator to be investigated for possible defeat devices:
    (1) The manufacturer must show to the satisfaction of the 
Administrator that the vehicle design does not incorporate strategies 
that unnecessarily reduce emission control effectiveness exhibited 
during the Federal Test Procedure or Supplemental Federal Test Procedure 
(FTP or SFTP) or the Highway Fuel Economy Test Procedure (described in 
subpart B of 40 CFR part 600), or the Air Conditioning Idle Test 
(described in Sec.86.165-12), when the vehicle is operated under

    (2) Optionally, a minimum of the percentage shown in Table S01-1 of 
a manufacturer's combined sales of the applicable model year's light-
duty vehicles and light light-duty trucks shall not exceed the 
applicable SFTP standards. Under this option, the light-duty vehicles 
shall not exceed the applicable SFTP standards in Sec.86.1811-01(b), 
and the light light-duty trucks shall not exceed the applicable SFTP 
standards in Sec.86.1812-01(b) or Sec.86.1813-01(b) as applicable.
    (3) Sales percentages for the purposes of determining compliance 
with the applicable SFTP emission standards shall be based on total 
actual U.S. sales of light-duty vehicles of the applicable model year by 
a manufacturer to a dealer, distributor, fleet operator, broker, or any 
other entity which comprises the point of first sale. If the option of 
paragraph (i)(2) of this section is taken, such sales percentages shall 
be based on the total actual combined U.S. sales of light-duty vehicles 
and light light-duty trucks of the applicable model year by a 
manufacturer to a dealer, distributor, fleet operator, broker, or any 
other entity which comprises the point of first sale.
    (4) The SFTP standards do not apply to vehicles or trucks certified 
on alternative fuels, but the standards do apply to the gasoline and 
diesel fuel operation of flexible fuel vehicles and trucks and dual fuel 
vehicles and trucks.
    (5) The SFTP standards do not apply to vehicles or trucks tested at 
high altitude.
    (6) The air to fuel ratio shall not be richer at any time than the 
leanest air to fuel mixture required to obtain maximum torque (lean best 
torque), plus a tolerance of six percent. The Administrator may approve 
a manufacturer's request for additional enrichment if it can be shown 
that additional enrichment is needed to protect the engine or emissions 
control hardware. For Tier 2 and interim non-Tier 2 vehicles, this 
provision does not apply to enrichment that occurs upon cold start, 
warm-up conditions and rapid-throttle motion conditions (``tip-in'' or 
``tip-out'' conditions).
    (7) The requirement to use a single roll dynamometer (or a 
dynamometer which produces equivalent results), discussed in Sec. Sec.
86.108-00, 86.118-00, and 86.129-00 of subpart B of this part, applies 
to all SFTP and FTP test elements as set forth in subpart B of this part 
for test groups which are designated as SFTP compliant under the 
implementation schedules in Tables S01-1 and S01-2 in paragraph (i)(1) 
of this section.
    (8) Small volume provisions. (i) Light-duty vehicles and light 
light-duty trucks manufactured by small volume manufacturers, as 
described in Sec.86.1801-01(d), are exempt from the requirements of 
this paragraph until model year 2002, when 100 percent compliance with 
the provisions of this paragraph (i) and the SFTP standards

[[Page 942]]

in Sec. Sec.86.1811-01(b) and 86.1812-01(b) is required. This 
exemption does not apply to small volume test groups as defined in Sec.
86.1838-01(b)(2).
    (ii) Heavy light-duty trucks manufactured by small volume 
manufacturers, as defined in Sec.86.1801-01, are exempt from the 
requirements of this paragraph (i) until model year 2004 when 100 
percent compliance with the provisions of this paragraph and the SFTP 
standards in Sec. Sec.86.1814-02(b) and 86.1815-02(b) is required. 
This exemption does not apply to small volume test groups as defined in 
Sec.86.1838-01(b)(2).
    (9) [Reserved]
    (10) The manufacturer must state at the time of Application for 
Certification, based on projected U.S. sales or projected production for 
U.S. sale, which test groups will be used to attain the required 
implementation schedule sales percentages for certification purposes.
    (11) A manufacturer cannot use one set of test groups to meet its 
intermediate useful life standards and another to meet its full useful 
life standards. The same test groups which are used to meet the 
intermediate useful life standards will be required to meet the 
corresponding full useful life standards.
    (12) Compliance with composite standards shall be demonstrated using 
the calculations set forth in Sec.86.164-00.
    (13) A/C-on specific calibrations. (i) For Tier 2 and interim non-
Tier 2 vehicles, A/C-on specific calibrations (e.g. air to fuel ratio, 
spark timing, and exhaust gas recirculation), may be used which differ 
from A/C-off calibrations for given engine operating conditions (e.g., 
engine speed, manifold pressure, coolant temperature, air charge 
temperature, and any other parameters).
    (ii) Such calibrations must not unnecessarily reduce the NMHC + 
NOX emission control effectiveness during A/C-on operation 
when the vehicle is operated under conditions which may reasonably be 
expected to be encountered during normal operation and use.
    (iii) If reductions in control system NMHC + NOX 
effectiveness do occur as a result of such calibrations, the 
manufacturer must, in the Application for Certification, specify the 
circumstances under which such reductions do occur, and the reason for 
the use of such calibrations resulting in such reductions in control 
system effectiveness.
    (iv) A/C-on specific ``open-loop'' or ``commanded enrichment'' air-
fuel enrichment strategies (as defined below), which differ from A/C-off 
``open-loop'' or ``commanded enrichment'' air-fuel enrichment 
strategies, may not be used, with the following exceptions: Cold-start 
and warm-up conditions, or, subject to Administrator approval, 
conditions requiring the protection of the vehicle, occupants, engine, 
or emission control hardware. Other than these exceptions, such 
strategies which are invoked based on manifold pressure, engine speed, 
throttle position, or other engine parameters must use the same engine 
parameter criteria for the invoking of this air-fuel enrichment strategy 
and the same degree of enrichment regardless of whether the A/C is on or 
off. ``Open-loop'' or ``commanded'' air-fuel enrichment strategy is 
defined as enrichment of the air to fuel ratio beyond stoichiometry for 
the purposes of increasing engine power output and the protection of 
engine or emissions control hardware. However, ``closed-loop biasing,'' 
defined as small changes in the air-fuel ratio for the purposes of 
optimizing vehicle emissions or driveability, must not be considered an 
``open-loop'' or ``commanded'' air-fuel enrichment strategy. In 
addition, ``transient'' air-fuel enrichment strategy (or ``tip-in'' and 
``tip-out'' enrichment), defined as the temporary use of an air-fuel 
ratio rich of stoichiometry at the beginning or duration of rapid 
throttle motion, must not be considered an ``open-loop'' or 
``commanded'' air-fuel enrichment strategy.
    (14) ``Lean-on-cruise'' calibration strategies. (i) For Tier 2 and 
interim non-Tier 2 vehicles, the manufacturer must state in the 
Application for Certification whether any ``lean-on-cruise'' strategies 
are incorporated into the vehicle design. A ``lean-on-cruise'' air-fuel 
calibration strategy is defined as the use of an air-fuel ratio 
significantly greater than stoichiometry, during non-deceleration 
conditions at speeds above 40 mph. ``Lean-on-cruise'' air-fuel 
calibration strategies must not

[[Page 943]]

be employed during vehicle operation in normal driving conditions, 
including A/C usage, unless at least one of the following conditions is 
met:
    (A) Such strategies are substantially employed during the FTP or 
SFTP;
    (B) Such strategies are demonstrated not to significantly reduce 
vehicle NMHC + NOX emission control effectiveness over the 
operating conditions in which they are employed; or
    (C) Such strategies are demonstrated to be necessary to protect the 
vehicle occupants, engine, or emission control hardware.
    (ii) If the manufacturer proposes to use a ``lean-on-cruise'' 
calibration strategy, the manufacturer must specify the circumstances 
under which such a calibration would be used, and the reason or reasons 
for the proposed use of such a calibration.
    (j) Evaporative emissions general provisions. (1) The evaporative 
standards in Sec. Sec.86.1811-01(d), 86.1811-04(e), 86.1812-01(d), 
86.1813-01(d), 86.1814-01(d), 86.1814-02(d), 86.1815-01(d), 1815-02(d) 
and 86.1816-04(d) apply equally to certification and in-use vehicles and 
trucks. The spitback standard also applies to newly assembled vehicles.
    (2) For certification testing only, manufacturers may conduct 
testing to quantify a level of non-fuel background emissions for an 
individual test vehicle. Such a demonstration must include a description 
of the source(s) of emissions and an estimated decay rate. The 
demonstrated level of non-fuel background emissions may be subtracted 
from evaporative emission test results from certification vehicles if 
approved in advance by the Administrator.
    (3) All fuel vapor generated in a gasoline- or methanol-fueled 
light-duty vehicle, light-duty truck, or complete heavy-duty vehicle 
during in-use operation shall be routed exclusively to the evaporative 
control system (e.g., either canister or engine purge.) The only 
exception to this requirement shall be for emergencies.
    (4) For certification purposes, where the applicable California 
evaporative emission standard is as stringent or more stringent than the 
applicable federal evaporative emission standard, the Administrator may 
accept California certification test data indicating compliance with the 
California standard to demonstrate compliance with the appropriate 
federal certification evaporative emission standard. The Administrator 
may require the manufacturer to provide comparative test data which 
clearly demonstrates that a vehicle meeting the California evaporative 
standard (when tested under California test conditions/test procedures) 
will also meet the appropriate federal evaporative emission standard 
when tested under federal test conditions/test procedures described in 
this part 86.
    (k) Refueling emissions general provisions--(1) Implementation 
schedules. (i) Tables S01-3, S01-4, and S01-5 in this paragraph 
(k)(1)(i) give the minimum percentage of a manufacturer's sales of the 
applicable model year's gasoline- and methanol-fueled Otto-cycle and 
petroleum-fueled and methanol-fueled diesel-cycle light-duty vehicles, 
light-duty trucks and complete heavy-duty vehicles which shall be tested 
under the applicable procedures in subpart B of this part, and shall not 
exceed the standards described in Sec. Sec.86.1811-01(e), 86.1811-
04(e)(3), 86.1812-01(e), 86.1813-01(e), and 86.1816-04(e). Vehicles 
waived from the emission standards under the provisions of paragraphs 
(m) and (n) of this section shall not be counted in the calculation of 
the percentage of compliance. Either manufacturer sales or actual 
production intended for sale in the United States may be used to 
determine combined volume, at the manufacturers option. Tables S01-3, 
S01-4, and S01-5 follow:

    (ii) Either manufacturer sales or actual production intended for 
sale in the United States may be used to determine combined volume, at 
the manufacturers option.
    (2) Determining sales percentages. Sales percentages for the 
purposes of determining compliance with the applicable refueling 
emission standards light-duty vehicles, light-duty trucks, medium-duty 
passenger vehicles, and complete heavy-duty vehicles shall be based on 
total actual U.S. sales of heavy light-duty trucks and complete heavy-
duty vehicles of the applicable model year by a manufacturer to a 
dealer, distributor, fleet operator, broker, or any other entity which 
comprises the point of first sale.
    (3) Refueling receptacle requirements. Compressed natural gas 
vehicles must meet the requirements for fueling connection devices as 
specified in Sec.86.1813-17(f)(1).
    (l) Fuel dispensing spitback testing waiver. (1) Vehicles certified 
to the refueling emission standards set forth in Sec. Sec.86.1811-
04(e), 86.1812-01(e), 86.1813-01(e), 86.1816-05(e) are not required to 
demonstrate compliance with the fuel dispensing spitback standard 
contained in that section provided that:
    (i) The manufacturer certifies that the vehicle inherently meets the 
fuel dispensing spitback standard as part of compliance with the 
refueling emission standard; and
    (ii) This certification is provided in writing and applies to the 
full useful life of the vehicle.
    (2) EPA retains the authority to require testing to enforce 
compliance and to prevent noncompliance with the fuel dispensing 
spitback standard.
    (m) [Reserved]
    (n) Fixed liquid level gauge waiver. Liquefied petroleum gas-fueled 
vehicles which contain fixed liquid level gauges or other gauges or 
valves which can be opened to release fuel or fuel vapor during 
refueling, and which are being tested for refueling emissions, are not 
required to be tested with such gauges or valves open, as outlined in 
Sec.86.157-98(d)(2), provided the manufacturer can demonstrate, to the 
satisfaction of the Administrator, that such gauges or valves would not 
be opened during refueling in-use due to inaccessibility or other design 
features that would prevent or make it very unlikely that such gauges or 
valves could be opened.
    (o) NMOG determination procedures. Measure NMOG emissions or 
determine NMOG emissions based on NMHC measurements using the procedures 
described in 40 CFR 1066.635. For Tier 2 and interim non-Tier 2 vehicles 
fueled by gasoline, manufacturers may instead measure NMHC and multiply 
the result by an adjustment factor of 1.04 before comparing with the 
NMOG standard to determine compliance with that standard.

Sec.86.1810-09  General standards; increase in emissions; 
unsafe condition; waivers.

    Section 86.1810-09 includes text that specifies requirements that 
differ from Sec.86.1810-01. Where a paragraph in Sec.86.1810-01 is 
identical and applicable to Sec.86.1810-09, this may be indicated by 
specifying the corresponding paragraph and the statement ``[Reserved]. 
For guidance see Sec.86.1810-01.'' Where a corresponding paragraph of 
Sec.86.1810-01 is not applicable, this is indicated by the statement 
``[Reserved]'' This section applies to model year 2009 and later light-
duty vehicles and light-duty trucks fueled by gasoline, diesel, 
methanol, ethanol, natural gas and liquefied petroleum gas fuels. This 
section also applies to MDPVs and complete heavy-duty vehicles certified 
according to the provisions of this subpart. Multi-fueled vehicles 
(including dual-fueled and flexible-fueled vehicles) must comply with 
all requirements established for each consumed fuel (or blend of fuels 
in the case of flexible fueled vehicles). The standards of this subpart 
apply to both certification and in-use vehicles

[[Page 945]]

unless otherwise indicated. This section also applies to hybrid electric 
vehicles and zero emission vehicles. Unless otherwise specified, 
requirements and provisions of this subpart applicable to methanol 
fueled vehicles are also applicable to Tier 2 and interim non-Tier 2 
ethanol fueled vehicles.
    (a) through (e) [Reserved] For guidance see Sec.86.1810-01.
    (f) Altitude requirements. (1) All emission standards apply at low 
altitude conditions and at high altitude conditions, with the following 
exceptions:
    (i) The supplemental exhaust emission standards as described in 
Sec.86.1811-04(f) apply only at low altitude conditions;
    (ii) The cold temperature NMHC emission standards as described in 
Sec.86.1811-10(g) apply only at low altitude conditions;
    (iii) The evaporative emission standards specified in Sec.86.1811-
09(e) apply at low altitude conditions. The evaporative emission 
standards specified in Sec.86.1811-04(e) continue to apply at high 
altitude conditions for 2009 and later model year vehicles.
    (2) For vehicles that comply with the cold temperature NMHC 
standards described in Sec.86.1811-10(g) and the CO2, 
N2O, and CH4 exhaust emission standards described 
in Sec.86.1818-12, manufacturers must submit an engineering evaluation 
indicating that common calibration approaches are utilized at high 
altitudes (except when there are specific high altitude calibration 
needs to deviate from low altitude emission control practices). Any 
deviation from low altitude emission control practices must be included 
in the auxiliary emission control device (AECD) descriptions submitted 
at certification. Any AECD specific to high altitude must require 
engineering emission data for EPA evaluation to quantify any emission 
impact and validity of the AECD.
    (g) through (p) [Reserved] For guidance see Sec.86.1810-01.

FR 39521, July 6, 2011; 77 FR 63156, Oct. 15, 2012]



Sec.86.1810-17  General requirements.

    The following provisions apply to all vehicles certified under this 
subpart:
    (a) Any device, system or element of design installed on or 
incorporated in a new motor vehicle to enable such vehicle to conform to 
the standards imposed by this subpart:
    (1) Shall not in its operation or function cause the emission into 
the ambient air of any noxious or toxic substance that would not be 
emitted in the operation of such vehicle without such system, except as 
specifically permitted by regulation; and
    (2) Shall not in its operation, function or malfunction result in 
any unsafe condition endangering the vehicle, its occupants, or persons 
or property in close proximity to the vehicle.
    (b) In establishing the physically adjustable range of each 
adjustable parameter on a new motor vehicle, the manufacturer shall 
ensure that, taking into consideration the production tolerances, safe 
vehicle drivability characteristics are available within that range.
    (c) Unless otherwise specified, the emission standards of this 
subpart apply equally for certification and for in-use vehicles 
throughout the specified useful-life period. Also, manufacturers must 
use good engineering judgment to determine that all of a vehicle's 
emission-related components are designed to operate properly throughout 
the specified useful-life period.
    (d) Vehicles may not discharge crankcase emissions into the ambient 
atmosphere.
    (e) All vehicles must have an onboard diagnostic system as described 
in Sec.86.1806.
    (f) Emission standards apply at low-altitude conditions and at high-
altitude conditions, except as noted in this subpart.
    (g) The cold temperature CO and NMHC standards in this subpart refer 
to test procedures set forth in subpart C of this part and 40 CFR part 
1066, subpart H. All other emission standards in this subpart rely on 
test procedures set forth in subpart B of this part. These procedures 
rely on the test specifications in 40 CFR parts 1065 and 1066 as 
described in subparts B and C of this part.
    (h) Multi-fueled vehicles (including dual-fueled and flexible-fueled 
vehicles) must comply with all the requirements

[[Page 946]]

established for each consumed fuel (and blend of fuels for flexible-
fueled vehicles). The following specific provisions apply for flexible-
fueled vehicles that operate on ethanol and gasoline:
    (1) For criteria exhaust emissions, we may identify the worst-case 
fuel blend for testing in addition to what is required for gasoline-
fueled vehicles. The worst-case fuel blend may be the fuel specified in 
40 CFR 1065.725, or it may consist of a combination of the fuels 
specified in 40 CFR 1065.710(b) and 1065.725. We may waive testing with 
the worst-case blended fuel for US06 and/or SC03 duty cycles; if we 
waive only SC03 testing, substitute the SC03 emission result using the 
standard test fuel for gasoline-fueled vehicles to calculate composite 
SFTP emissions.
    (2) For refueling emissions, we may identify the worst-case fuel 
blend for testing in addition to what is required for gasoline-fueled 
vehicles. The worst-case fuel blend may consist of a combination of the 
fuels specified in 40 CFR 1065.710(c) and 1065.725. This is generally 
expected to be a fuel blend with 10 percent ethanol and a nominal Dry 
Vapor Pressure Equivalent of 10 psi. You may prepare such a worst-case 
fuel blend by mixing it before dispensing into the vehicle's fuel tank, 
or by consecutively dispensing appropriate amounts of the two specified 
fuels into a fuel tank.
    (3) No additional spitback or evaporative emission testing is 
required beyond the emission measurements with the gasoline test fuel 
specified in 40 CFR 1065.710.
    (i) Where we specify requirements based on a percentage of total 
sales volume in a given model year, you may instead ask us to calculate 
the percentage based on production volumes instead of sales volumes.

Sec.86.1811-04  Emission standards for light-duty vehicles, light-duty
trucks and medium-duty passenger vehicles.

    (a) Applicability. (1) This section contains regulations 
implementing emission standards for all LDVs, LDTs and MDPVs. This 
section applies to 2004 and later model year LDVs, LDTs and MDPVs fueled 
by gasoline, diesel, methanol, ethanol, natural gas and liquefied 
petroleum gas fuels, except as noted. Additionally, this section 
contains provisions applicable to hybrid electric vehicles (HEVs) and 
zero emission vehicles (ZEVs). Multi-fueled vehicles must comply with 
all requirements established for each consumed fuel.
    (2) This section also applies to LDVs, LDTs and MDPVs of model years 
prior to 2004, when manufacturers certify such vehicles to Tier 2 
exhaust emission requirements to utilize alternate phase-in schedules, 
as allowed under paragraph (k)(6) of this section, and/or to earn early 
NOX credits for use in complying with the Tier 2 fleet 
average NOX standard which takes effect in the 2004 model 
year for LDV/LLDTs and 2008 for HLDT/MDPVs.
    (3) Except where otherwise specified, this section applies instead 
of Sec. Sec.86.1811-01, 86.1812-01, 86.1813-01, 86.1814-01, 86.1814-
02, 86.1815-01, and 86.1815-02.
    (4) Except where otherwise specified, the provisions of this section 
apply equally to LDVs and all categories of LDTs, and to all MDPVs. 
Numerous provisions are applicable equally to HLDTs and MDPVs, as 
reflected by the term HLDT/MDPV. Numerous provisions apply equally to 
LDVs and LLDTs as reflected by the term LDV/LLDT.
    (5) The exhaust emission standards and evaporative emission 
standards of this section apply equally to certification and in-use 
LDVs, LDTs and MDPVs, unless otherwise specified.
    (b) Test weight. (1) Except as required in paragraphs (b)(2) and 
(b)(4) of this section, or permitted under paragraph (b)(3) of this 
section, emission testing of all LDVs, LDTs and MDPVs to determine 
compliance with any exhaust or evaporative emission standard set forth 
in this part must be on a loaded vehicle weight (LVW) basis, as that 
term is defined in this subpart.
    (2) Interim non-Tier 2 HLDTs tested to Tier 1 SFTP standards, must 
be tested on an adjusted loaded vehicle weight (ALVW) basis, as that 
term is defined in this subpart, during the SC03 element of the SFTP.
    (3) Except as required in paragraphs (b)(2) and (b)(4) of this 
section, interim

[[Page 947]]

non-Tier 2 HLDT/MDPVs may be tested on an ALVW basis or an LVW basis to 
demonstrate compliance with any exhaust or evaporative emission standard 
set forth in this part.
    (4) MDPVs certified to bin 11 standards from Tables S04-1 and -2 
must be tested on an ALVW basis to demonstrate compliance with any 
exhaust emission standard set forth in this part.
    (c) Tier 2 FTP exhaust emission standards. Exhaust emissions from 
Tier 2 vehicles must not exceed the standards in Table S04-1 of this 
section at full useful life when tested over the Federal Test Procedure 
(FTP) described in subpart B of this part. Exhaust emissions from Tier 2 
vehicles must not exceed the standards in Table S04-2 of this section at 
intermediate useful life, if applicable, when tested over the FTP.
    (1) For a given test group a manufacturer desires to certify to 
operate only on one fuel, the manufacturer must select a set of 
standards from the same bin (line or row) in Table S04-1 of this section 
for non-methane organic gases (NMOG), carbon monoxide (CO), oxides of 
nitrogen (NOX), formaldehyde (HCHO) and particulate matter 
(PM). The manufacturer must certify the test group to meet those 
standards, subject to all the applicable provisions of this subpart. The 
manufacturer must also certify the test group to meet the intermediate 
useful life standards (if any) in Table S04-2 of this section having the 
same EPA bin reference number as the chosen full useful life standards.
    (2) For a given test group of flexible-fueled, bi-fuel or dual fuel 
vehicles when operated on the alcohol or gaseous fuel they are designed 
to use, manufacturers must select a bin of standards from Table S04-1 of 
this section and the corresponding bin in Table S04-2, if any. When 
these flexible-fueled, bi-fuel or dual fuel vehicles are certified to 
operate on gasoline or diesel fuel, the manufacturer may choose to 
comply with the next numerically higher applicable NMOG standard, if 
any, above the bin which contains the standards selected for 
certification on the gaseous or alcohol fuel.
    (3)(i) For a given test group of flexible-fueled, bi-fuel or dual 
fuel vehicles certified to bin 10 in Table S04-1, when operated on the 
alcohol or gaseous fuel they are designed to use, manufacturers may 
choose to comply with an NMOG standard of 0.230 for LDV/LLDTs or 0.280 
g/mi for HLDT/MDPVs at full useful life and corresponding intermediate 
life standards of 0.160 g/mi and 0.195 g/mi, respectively, when these 
flexible-fueled, bi-fuel or dual fuel vehicles are certified to operate 
on gasoline or diesel fuel.
    (ii) For a given test group of flexible-fueled, bi-fuel or dual fuel 
vehicles certified to bin 8 in Table S04-1, when operated on the alcohol 
or gaseous fuel they are designed to use, manufacturers may choose to 
comply with a NMOG standard of 0.156 g/mi for LDV/LLDTs and 0.180 for 
HLDT/MDPVs at full useful life and corresponding intermediate life 
standards of 0.125 g/mi and 0.140 g/mi, respectively, when these 
flexible-fueled, bi-fuel or dual fuel vehicles are certified to operate 
on gasoline or diesel fuel.
    (4)(i) For bins where intermediate life standards are applicable, a 
manufacturer may elect not to comply with such standards. Except as 
permitted in paragraph (c)(4)(iv) of this section, the manufacturer must 
certify such vehicles to a useful life of 15 years or 150,000 miles, 
whichever occurs first, for LDV/LLDTs and HLDT/MDPVs.
    (ii) A manufacturer electing not to comply with intermediate life 
standards, as permitted in paragraph (c)(4)(i) of this section, may not 
generate additional NOX credits as described under Sec.
86.1860-04 (g), except as permitted in paragraph (c)(4)(iii) of this 
section.
    (iii) For bins where intermediate life standards are not applicable, 
or are specified to be optional by paragraph (c)(4)(iv) of this section, 
a manufacturer may generate additional NOX credits subject to 
the provisions in Sec.86.1860-04 (g).
    (iv) For diesel vehicles certified to bin 9 or bin 10, intermediate 
life standards are optional regardless of whether the manufacturer 
certifies the test group to a full useful life of 120,000 miles or 
150,000 miles.
    (5) In a given model year, an individual vehicle may not be included 
in both the Tier 2 program and an interim program.

    (d) Fleet average NOX Standards. (1)(i) For a given 
individual model year's sales of Tier 2 vehicles, including model years 
during the phase-in years of the Tier 2 standards, manufacturers must 
comply with a fleet average oxides of nitrogen (NOX) standard 
of 0.07 grams per mile. The manufacturer must calculate its fleet 
average NOX emission level(s) as described in Sec.86.1860-
04. Up through and including model year 2008, manufacturers must 
calculate separate fleet average NOX emission levels for LDV/
LLDTs and for HLDT/MDPVs as described in Sec.86.1860-04.
    (ii) During a phase-in year, the manufacturer must comply with the 
0.07 g/mi fleet average standard for the required phase-in percentage 
for that year as specified in paragraph (k)(1) of this section, or for 
the alternate phase-in percentage as permitted under paragraph (k)(6) of 
this section.
    (2) For Early Tier 2 LDV/LLDTs. For model years prior to 2004, where 
the manufacturer desires to bank early Tier 2 NOX credits as 
permitted under Sec.86.1861(c), the manufacturer must comply with a 
fleet average standard of 0.07 grams per mile for its Tier 2 LDV/LLDTs. 
Manufacturers must determine compliance with the NOX fleet 
average standard according to regulations in Sec.86.1860-04 of this 
subpart.

[[Page 949]]

    (3) For Early Tier 2 HLDT/MDPVs. For model years prior to 2008, 
where the manufacturer desires to bank early Tier 2 NOX 
credits as permitted under Sec.86.1861(c), the manufacturer must 
comply with a fleet average standard of 0.07 grams per mile for its Tier 
2 HLDT/MDPVs. Manufacturers must determine compliance with the 
NOX fleet average standard according to regulations in Sec.
86.1860-04.
    (e) Evaporative emission standards. Consistent with the phase-in 
requirements in paragraph (k) of this section, evaporative emissions 
from gasoline-fueled, natural gas-fueled, liquefied petroleum gas-
fueled, ethanol-fueled and methanol-fueled vehicles must not exceed the 
standards in this paragraph (e). The standards apply equally to 
certification and in-use vehicles.
    (1) Diurnal-plus-hot soak evaporative hydrocarbon standards. 
Hydrocarbons for LDV/LLDTs, HLDTs and MDPVs must not exceed the diurnal 
plus hot soak standards shown in Table S04-3 for the full three diurnal

    (2) Running loss standard. Hydrocarbons for LDVs, LDTs and MDPVs 
measured on the running loss test must not exceed 0.05 grams per mile.
    (3) Refueling emission standards. Refueling emissions must not 
exceed the following standards:
    (i) For gasoline-fueled and methanol-fueled LDV, LDT and MDPV: 0.20 
grams hydrocarbon per gallon (0.053 grams per liter) of fuel dispensed. 
This standard also applies for diesel-fueled LDV.
    (ii) For liquefied petroleum gas-fueled LDV, LDTs and MDPVs: 0.15 
grams hydrocarbon per gallon (0.04 grams per liter) of fuel dispensed.
    (iii) Refueling standards for HLDTs are subject to the phase-in 
requirements found in Sec.86.1810-01(k). MDPVs must also comply with 
the phase-in requirement in Sec.86.1810-01(k) and must be grouped with 
HLDTs to determine phase-in compliance.
    (4) Spitback standards. For gasoline and methanol fueled LDV/Ts and 
MDPVs, hydrocarbons measured on the fuel dispensing spitback test must 
not exceed 1.0 grams hydrocarbon (carbon if methanol-fueled) per test.
    (5) Evaporative emission requirements for interim vehicles. (i) LDV/
Ts not certified to meet the evaporative emission standards in this 
paragraph (e) as permitted under the phase-in schedule of paragraph (k) 
of this section, must meet applicable evaporative emission standards in 
Sec.86.1811-01, Sec.86.1812-01, Sec.86.1813-01, Sec.86.1814-02 
or Sec.86.1815-02 except that all LDV/Ts must meet the refueling 
emission standards in paragraph (e)(3) of this section.
    (ii) MDPVs not certified to meet the evaporative emission standards 
in this paragraph (e) as permitted under the phase-in schedule of 
paragraph (k) of this section, must meet applicable evaporative emission 
standards for heavy-duty vehicles in Sec.86.099-10.
    (6) In cases where applicable California emission standards are as 
stringent or more stringent than applicable standards specified under 
this paragraph (e), the Administrator may accept data indicating 
compliance with California standards to demonstrate compliance for 
certification purposes with the standards required under this paragraph 
(e). The Administrator may require manufacturers to provide comparative 
test data to show that a vehicle meeting California standards under 
California test conditions and procedures will also meet the standards 
under this paragraph (e) when tested under test conditions and 
procedures in this part 86.
    (f) Supplemental exhaust emission standards for LDV/Ts. (1) 
Supplemental exhaust emission standards are applicable to gasoline and 
diesel-fueled LDV/Ts but are not applicable to MDPVs, alternative fueled 
LDV/Ts, or flexible fueled LDV/Ts when operated on a fuel other than 
gasoline or diesel. Except as otherwise specified in this

[[Page 950]]

paragraph (f), manufacturers must comply with 4000 mile and full useful 
life SFTP standards as determined in this paragraph (f). The 4000 mile 
SFTP standards must be taken from Table S04-4 and the full life SFTP 
standards must be calculated using the formula in paragraph (f)(2) of 
this section. Table S04-4 follows:

    (2)(i) Manufacturers must calculate their applicable full useful 
life SFTP standards for NMHC + NOX, PM and for CO, if using 
the weighted CO standard. If not using the weighted CO standard, 
manufacturers may use the full useful life standalone Tier 1 standards 
for US06 and SC03. To calculate the applicable full useful life weighted 
NMHC + NOX, PM and CO standards, manufacturers must use the 
following formula:

SFTP Standard = SFTP Standard1-[0.35 x (FTP 
Standard1-Current FTP Standard)]

Where:

SFTP Standard = Applicable full life weighted SFTP standard for NMHC + 
          NOX, PM or CO. The NMHC + NOX and PM 
          standards must be rounded to two decimal places and the CO 
          standard must be rounded to one decimal place.
SFTP Standard1 = Applicable full life Tier 1 SFTP standard 
          for NMHC + NOX or CO from Table S04-5. For PM only, 
          use FTP Standard1 for SFTP Standard1.
FTP Standard1 = Applicable full life Tier 1 FTP standard from 
          Table S04-6 in this paragraph (f). For the Tier 1 NMHC + 
          NOX standard, add the applicable NMHC and NOx 
          standards.
Current FTP Standard = Applicable full life FTP standard from Table S04-
          1 in paragraph (c) of this section. For the current NMHC + 
          NOX standard, add the NMOG and NOX 
          standards from the applicable bin.

    (ii)(A) Manufacturers must determine compliance with NMHC + 
NOX, CO and PM weighted SFTP standards calculated in 
paragraph (f)(2)(i) of this section by weighting their emission results 
as follows:

0.35 x (FTP) + 0.28 x (US06) + 0.37 x (SC03).

    (B) The results of the calculation in paragraph (f)(2)(ii)(A) of 
this section must be rounded to one more decimal place than the 
applicable standard calculated in paragraph (f)(2)(i) of this section 
and then compared with that standard.
    (3) For interim non-Tier 2 gasoline, diesel and flexible-fueled 
LDT3s and LDT4s, manufacturers may, alternatively, meet the gasoline-
fueled vehicle SFTP standards found in Sec. Sec.86.1814-02 and 
86.1815-02, respectively.
    (4) Interim non-Tier 2 gasoline, diesel and flexible-fueled LDV/
LLDTs certified to bin 10 FTP exhaust emission standards from Table S04-
1 in paragraph (c) of this section may meet the gasoline Tier 1 SFTP 
requirements found at Sec. Sec.86.1811-01(b), 86.1812-01(b), 86.1813-
01(b), for LDVs, LDT1s, and LDT2s, respectively.
    (5) SFTP standards for PM are not applicable to interim non-Tier 2 
LDV/Ts. For Tier 2 LDV/Ts, the 4000 mile PM standard is equal to the 
full life PM standard calculated under paragraph (f)(2) of this section. 
The requirements of this paragraph (f)(5) also apply to Tier 2 flexible 
fuel vehicles when operated on gasoline or diesel fuel. (See regulations 
in Sec.86.1829-01(b)(1)(iii)(B) regarding data submittal for PM 
results for gasoline vehicles.)
    (6)(i) In lieu of complying with 4000 mile SFTP standards described 
in this paragraph, diesel LDV/LLDTs through model year 2006, may comply 
instead with intermediate life SFTP standards derived from Tier 1 
intermediate life SFTP standards for gasoline vehicles.
    (ii) To calculate intermediate life SFTP standards, substitute 
intermediate life Tier 1 FTP and SFTP values from Tables S04-5 and S04-6 
in this paragraph (f), as appropriate, for the full life values in the 
equation in paragraph (f)(2)(i) of this section. Substitute the 
applicable intermediate life standards for the full life current FTP 
standard. If there is no applicable intermediate life standard use the 
full life current FTP standard.
    (iii) A manufacturer of diesel LDV/LLDTs must declare which option 
it will use (4,000 mile or intermediate life standards) in Part I of its 
certification application.
    (7) For diesel vehicles certified to the bin 9 or bin 10 standards 
of paragraph (c) of this section, 4000 mile SFTP and intermediate life 
SFTP standards are optional regardless of whether the manufacturer 
certifies the test group to a full useful life of 120,000 miles or 
150,000 miles.
    (8)(i) For model year 2007 through 2009 diesel LDVs and diesel LDT1s 
only, a manufacturer may optionally comply with the 4000 mile US06 NMHC 
+ NOX standard shown in Table S04-4 for LDT2s (0.25 g/mile), 
instead of the standards for LDV/LDT1s (0.14 g/mile). A manufacturer 
choosing this option also must comply with intermediate life SFTP NMHC + 
NOX standards determined using the calculation described 
under paragraph (f)(6)(ii) of this section. A manufacturer choosing this 
option must comply with the SFTP NMHC + NOX standard 
determined under paragraph (f)(6)(ii) not only at intermediate life but 
also at full useful life and must certify such vehicles to this SFTP 
NMHC + NOX standard for a full useful life of 150,000 miles 
or 15 years, whichever occurs first.
    (ii) In Part I of its certification application for model years 2007 
through 2009, a manufacturer of diesel LDV/LDT1s must declare which 
provision it will use (the base Tier 2 provision of paragraphs (f)(1) 
and (f)(2) of this section or the option described in paragraph 
(f)(8)(i) of this section).
    (g) Cold temperature exhaust emission standards. These standards are 
applicable only to gasoline fueled LDV/Ts and MDPVs. For cold 
temperature exhaust emission standards, a useful life of 50,000 miles 
applies.
    (1) For LDVs and LDT1s, the standard is 10.0 grams per mile CO.
    (2) For LDT2s, LDT3s and LDT4s, and MDPVs the standard is 12.5 grams 
per mile CO.
    (3) These standards do not apply to interim non-Tier 2 MDPVs.
    (h) [Reserved]

[[Page 952]]

    (i) Idle CO standards and references to such standards in this 
subpart, do not apply to any 2004 or later model year LDV, LDT, or MDPV 
or to any LDV, LDT or MDPV certified to Tier 2 standards before model 
year 2004 for purposes of generating early NOX credits or 
meeting the requirements of an alternative phase-in schedule that begins 
prior to the 2004 model year.
    (j) Highway NOX exhaust emission standard. The NOX 
emissions measured on the federal Highway Fuel Economy Test in 40 CFR 
1066.840 must not be greater than 1.33 times the applicable FTP 
NOX standard to which the manufacturer certifies the test 
group. Both the measured emissions and the product of the NOX 
standard and 1.33 must be rounded to the nearest 0.01 g/mi before being 
compared.
    (k) Phase-in of the Tier 2 FTP exhaust and evaporative requirements; 
small volume manufacturer flexibilities. (1) Manufacturers must comply 
with the phase-in requirements in Tables S04-7 and S04-8 of this 
paragraph (k) for the Tier 2 FTP exhaust emission requirements specified 
in paragraph (c) of this section. Separate phase-in schedules are 
provided for LDV/LLDTs and for HLDT/MDPVs. These requirements specify 
the minimum percentage of the manufacturer's LDV/LLDT and HLDT/MDPV U.S. 
sales, by model year, that must meet the Tier 2 requirements, including 
the applicable fleet average standard, for their full useful lives. As 
the terms LDV/LLDT and HLDT/MDVP imply, LDVs and LLDTs must be grouped 
together to determine compliance with these phase-in requirements and 
HLDTs and MDPVs must also be grouped together to determine compliance 
with these phase-in requirements. Tables S04-7 and S04-8 follow:

    (2) Manufacturers must also comply with the phase-in requirements in 
Tables S04-7 and S04-8 of this paragraph (k) for the evaporative 
emission requirements contained in paragraph (e) of this section.
    (3) Manufacturers may opt to use different LDV/LLDTs and HLDT/MDPVs 
to meet the phase-in requirements for evaporative emissions and FTP 
exhaust emissions, provided that the manufacturer meets the minimum 
applicable phase-in requirements in Table S04-7 and Table S04-8 of this 
paragraph (k) for both FTP exhaust and evaporative emissions. A LDV, LDT 
or MDPV counted toward compliance with any phase-in requirement for FTP 
exhaust or evaporative standards, must comply with all applicable Tier 2 
exhaust requirements or all applicable evaporative requirements, 
respectively, described in this section.
    (4) LDVs, LDTs and MDPVs not certified to meet the Tier 2 FTP 
exhaust requirements during model years 2004-2008, as allowed under this 
subpart, are subject to the provisions of paragraph (l) of this section.
    (5) Provisions for small volume manufacturers. (i) Small volume 
manufacturers, as defined in this part, are exempt from the Tier 2 LDV/
LLDT exhaust and evaporative emissions phase-in requirements for model 
years 2004, 2005 and 2006 in Table S04-7 of this paragraph (k), but must 
comply with the 100% requirement for the 2007 and later model years for 
exhaust and evaporative emissions. If not complying with Tier 2 
requirements during 2004, 2005 and 2006, small volume manufacturers must 
comply with the requirements for interim non-Tier 2 LDV/LLDTs.
    (ii) Small volume manufacturers, as defined in this part, are exempt 
from the HLDT/MDPV exhaust and evaporative phase-in requirement for 
model year 2008 in Table S04-8 of this section

[[Page 953]]

but must comply with the 100% requirement for the 2009 model year. Small 
volume manufacturers are also exempt from the HLDT/MDPV interim fleet 
average NOX standard (0.20 g/mi) and its phase-in for the 
2004, 2005 and 2006 model years.
    (iii) Small volume manufacturers must comply with the FTP exhaust 
emission standards from Tables S04-1 and 2 of paragraph (c) of this 
section for all HLDT/MDPVs of model years 2004 and later, except that 
2004 model year HLDTs may comply with Tier 1 exhaust emission standards 
subject to the provisions of paragraph (l)(2)(vii) of this section, and 
2004 model year MDPVs may comply with heavy-duty vehicle standards 
subject to the provisions of paragraph (l)(2)(viii) of this section. 
Small volume manufacturers must also comply with the 0.20 g/mi fleet 
average NOX standard for 2007 and 2008 model year HLDT/MDPVs; 
the Tier 2 0.07 g/mi fleet average NOX standard for the 2009 
and later model year HLDT/MDPVs; and the evaporative emission standards 
in Table S04-3 of this section for the 2009 and later model years.
    (iv) Vehicles produced by small volume manufacturers, as defined in 
Sec.86.1838-01, are exempt from the LDV/LLDT evaporative emissions 
standards in Table S09-1 of Sec.86.1811-09(e) for model years 2009 and 
2010, but must comply with the Tier 2 evaporative emission standards in 
Table S04-3 in paragraph (e)(1) of this section for model years 2009 and 
2010.
    (v) Vehicles produced by small volume manufacturers, as defined in 
Sec.86.1838-01, are exempt from the HLDT/MDPV evaporative emissions 
standards in Table S09-1 of Sec.86.1811-09(e) for model years 2010 and 
2011, but must comply with the Tier 2 evaporative emission standards in 
Table S04-3 in paragraph (e)(1) of this section for model years 2010 and 
2011.
    (vi) Small volume manufacturers, as defined in Sec.86.1838-01, are 
exempt from the LDV/LLDT cold temperature NMHC phase-in requirements in 
Table S10-1 of Sec.86.1811-10(g) for model years 2010, 2011, and 2012, 
but must comply with the 100% requirement for 2013 and later model years 
for cold temperature NMHC standards.
    (vii) Small volume manufacturers, as defined in Sec.86.1838-01, 
are exempt from the HLDT/MDPV cold temperature NMHC phase-in 
requirements in Table S10-1 of Sec.86.1811-10(g) for model years 2012, 
2013, and 2014, but must comply with the 100% requirement for 2015 and 
later model years for cold temperature NMHC standards.
    (6)(i) A manufacturer may elect an alternate phase-in schedule that 
results in 100% phase-in for LDV/LLDTs by 2007. Alternate phase-in 
schedules must produce a sum of at least 250% when the percentages of 
LDV/LLDTs certified to Tier 2 requirements for each model year from 2001 
through 2007 are summed. As an example, a 10/25/50/65/100 percent phase-
in that began in 2003 would have a sum of 250 percent and would be 
acceptable. However, a 10/25/40/70/100 percent phase-in that began the 
same year would have a sum of 245 percent and would not be acceptable.
    (ii) A manufacturer electing this option for LDV/LLDTs may calculate 
its compliance with the evaporative standards in paragraph (e)(1) of 
this section separately from its compliance with Tier 2 exhaust 
standards, provided that the phase-in schedules for each separately 
produce a sum of at least 250 percent when calculated as described in 
paragraph (k)(6)(i) of this section. A vehicle counted towards 
compliance with any phase-in requirement for the Tier 2 exhaust 
standards or the evaporative standards in paragraph (e)(1) of this 
section, must comply with all applicable Tier 2 exhaust standards or all 
evaporative standards, as applicable, described in this section.
    (iii) In addition to the requirements of paragraphs (k)(6)(i) and 
(ii) of this section, except as permitted in paragraph (k)(6)(vii) of 
this section, a manufacturer of LDV/LLDTs electing to use an alternate 
phase-in schedule for compliance with the Tier 2 exhaust standards or 
the evaporative standards in paragraph (e)(1) of this section must 
ensure that the sum of the percentages of vehicles from model years 2001 
through 2004, meeting such exhaust or evaporative standards, as 
applicable, is at least 25%.
    (iv) A manufacturer may elect an alternate phase-in schedule that 
results in 100% phase-in for HLDT/MDPVs by

[[Page 954]]

2009. The requirements of paragraphs (k)(6)(i) through (k)(6)(ii) of 
this section apply, except that for HLDT/MDPVs, the calculation 
described in paragraphs (k)(6)(i) and (k)(6)(ii) of this section may 
cover model years 2001 through 2009 and must produce a sum of at least 
150%.
    (v) A manufacturer electing to use any alternate phase-in schedule 
permitted under this section must provide in its Application for 
Certification for the first year in which it intends to use such a 
schedule, and in each succeeding year during the phase-in, the intended 
phase-in percentages for that model year and the remaining phase-in 
years along with the intended final sum of those percentages as 
described in this paragraph (k)(6). This information may be included 
with the information required under Sec.86.1844-01(d)(13). In its year 
end annual reports, as required under Sec.86.1844-01(e)(4) the 
manufacturer must include sufficient information so that the 
Administrator can verify compliance with the alternative phase-in 
schedule established under paragraph (k)(6) of this section.
    (vi) Under an alternate phase-in schedule, the projected phase-in 
percentage is not binding for a given model year, provided the sums of 
the actual phase-in percentages that occur meet the appropriate total 
sums as required in paragraph (k)(6) of this section, and provided that 
100% actual compliance is reached for the appropriate model year, either 
2007 or 2009, as described in paragraph (k)(6) of this section.
    (vii) A manufacturer unable to meet the 25% requirement in paragraph 
(k)(6)(iii) of this section, must:
    (A) Ensure that the sum of the percentages of vehicles for model 
years 2001 through 2004, meeting such exhaust or evaporative standards, 
as applicable, is at least 20%.
    (B) Subtract that sum of percentages for model years 2001 through 
2004 from 25%, and multiply the unrounded result by 2.
    (C) Round the product from paragraph (k)(6)(vii)(B) of this section 
to the nearest 0.1% and add that to 50%. That sum becomes the required 
phase-in percentage for the 2005 model year.
    (D) Comply with the phase-in percentage for the 2005 model year 
determined in paragraph (k)(6)(vii)(C) of this section.
    (E) Comply with a minimum phase-in percentage for the 2006 model 
year determined by the following equation:

minimum phase-in percentage for 2006 = [75% - (2005api - 
2005rpi)]

Where:

2005rpi = the required phase-in for the 2005 model year as 
          determined in paragraph (k)(6)(vii)(C) of this section; and
2005api = the manufacturer's actual phase-in quantity for the 
          2005 model year.

    (7)(i) Sales percentages for the purpose of determining compliance 
with the phase-in of the Tier 2 requirements and the phase-in of the 
evaporative standards in paragraph (e)(1) of this section, must be based 
upon projected U.S. sales of LDV/LLDTs and HLDT/MDPVs of the applicable 
model year by the manufacturer to the point of first sale. Such sales 
percentages must be rounded to the nearest one tenth of a percent, and 
must not include vehicles and trucks projected to be sold to points of 
first sale in California or a state that has adopted California 
requirements for that model year as permitted under section 177 of the 
Act.
    (ii) Alternatively, the manufacturer may petition the Administrator 
to allow actual volume produced for U.S. sales to be used in lieu of 
projected U.S. sales for purposes of determining compliance with the 
phase-in percentage requirements under this section. The manufacturer 
must submit its petition within 30 days of the end of the model year to 
the Vehicle Programs and Compliance Division. For EPA to approve the use 
of actual volume produced for U.S. sales, the manufacturer must 
establish to the satisfaction of the Administrator, that actual 
production volume is functionally equivalent to actual sales volume of 
LDV/LLDTs and HLDT/MDPVs sold in states other than California and states 
that have adopted California standards.
    (iii) Manufacturers must submit information showing compliance with 
all phase-in requirements of this section with its Part I application as 
required by Sec.86.1844(d)(13).

    (l) FTP exhaust standards for interim non-Tier 2 vehicles--(1) FTP 
exhaust emission standards for interim non-Tier 2 LDV/LLDTs. (i) LDV/
LLDTs that are not used to meet the Tier 2 phase-in requirements 
including the Tier 2 fleet average NOX requirement during the 
Tier 2 phase-in period (model years 2004-2006) must comply with the full 
useful life FTP exhaust emission standards listed in Table S04-1 of 
paragraph (c) of this section and the corresponding intermediate useful 
life standards, if any, in Table S04-2 of paragraph (c) of this section. 
Manufacturers may choose the bin of full useful life standards to which 
they certify a test group of vehicles, subject to the requirements in 
paragraph (l)(3)(i) of this section. In a given model year, an 
individual vehicle may not be used to comply with both the Tier 2 fleet 
average NOX standard and the applicable interim fleet average 
NOX standard although vehicles from the same test group may 
be separated and the vehicles counted toward compliance with either 
program.
    (ii) The provisions of paragraphs (c) (1), (2) and (3) of this 
section apply to flexible-fueled, dual fuel and multi-fuel interim non-
Tier 2 LDV/LLDTs.
    (iii) Only manufacturers that comply with the applicable FTP 
standards in Tables S04-1 and 2 of paragraph (c) of this section for all 
of their 2004 model year HLDTs and declare their intention to comply 
with the 2004 model year 25% phase-in requirement to the 0.20 g/mi 
interim fleet average NOX standard for HLDTs (or HLDT/MDPVs) 
described in this paragraph (l) may use the optional higher NMOG values 
for interim LDT2s certified to bin 9 standards that are shown in Tables 
S04-1 and 2. Manufacturers must declare their intention to comply with 
the full 2004 model year 25% phase-in requirement in Part I of their 
HLDT or their HLDT/MDPV, as applicable, certification applications.
    (iv) The provisions of paragraph (c)(4) of this section apply to 
interim non-Tier 2 vehicles.
    (2) FTP exhaust emission standards for interim non-Tier 2 HLDTs and 
interim non-Tier 2 MDPVs. (i) Except as permitted under paragraphs 
(l)(2) (vii) and (viii) of this section, HLDTs and MDPVs of model years 
2004-2008 that are not used to meet the Tier 2 FTP phase-in requirements 
including the Tier 2 fleet average NOX requirement must 
comply with the full useful life FTP exhaust emission standards listed 
in Table S04-1 of paragraph (c) of this section and, the corresponding 
intermediate useful life standards, if any, in Table S04-2 of paragraph 
(c) of this section. Manufacturers may choose the bin of full useful 
life standards to which they certify a test group of vehicles, subject 
to the requirements in paragraph (l)(3)(ii) of this section.
    (ii) Except as permitted under paragraphs (l)(2) (vii) and (viii) of 
this section, HLDTs and MDPVs of model years 2004-2008 that are not used 
to meet the Tier 2 FTP phase-in requirements including the Tier 2 fleet 
average NOX requirement must comply with the fleet average 
NOX standard described in paragraph (l)(3)(ii) of this 
section subject to the phase-in schedule in paragraph (l)(2)(iv) of this 
section, i.e. 25 percent of the HLDT and MDPVs must meet the fleet 
average standard of 0.20 g/mi in 2004, 50 percent in 2005, and so on.
    (iii) Manufacturers may choose the bin of full useful life standards 
and corresponding intermediate life standards to which they certify test 
groups of HLDTs and MDPVs, subject to the requirements in paragraph 
(l)(3)(ii) of this section. Manufacturers may include HLDT/MDPVs in the 
interim program that are not used to meet the Tier 2 fleet average 
NOX standard or the phase-in percentage requirements in the 
Tier 2 program or to generate Tier 2 NOX credits. In a given 
model year, an individual vehicle may not be used to comply with both 
the Tier 2 fleet average NOX standard and the applicable 
interim fleet average NOX standard although vehicles from the 
same test group may be separated and the vehicles counted toward 
compliance with either program.
    (iv) Phase-in schedule for interim non-Tier 2 HLDT/MDPVs. Table S04-
9 of this paragraph (l) specifies the minimum percentage of the 
manufacturer's interim non-Tier 2 HLDT/MDPV U.S. sales, by model year, 
that must comply

    (v)(A) A manufacturer may elect an alternate phase-in schedule, 
beginning as early as the 2001 model year, that results in 100% 
compliance by 2007 with the fleet average NOX standard for 
interim non-Tier 2 HLDT/MDPVs described in paragraph (l)(3)(ii) of this 
section. The requirements of paragraph (k)(6) of this section apply to 
the selection of an alternate phase-in schedule.
    (B) If a manufacturer elects not to bring all of its HLDT/MDPVs into 
compliance with the interim requirements in 2004 as permitted under 
paragraphs (l)(2)(vii) and
    (viii) of this section, it may still use an alternate phase-in 
schedule to attain 100% compliance with the interim fleet average 
NOX standard for HLDT/MDPVs, but the sum of phase-in 
percentages it must meet will be 225% rather than 250%. If the 
manufacturer commences its 2004 model year on or after December 21, 
2003, for any HLDT/MDPVs, the manufacturer must increase the 225% by the 
fraction of its 2004 model year HLDT/MDPVs whose model year commenced on 
or after that date and which were brought into compliance with the 0.20 
g/mi corporate average NOX standard as required under 
paragraph (l)(2)(ix) of this section. The manufacturer must ensure that 
the sum of the percentages of vehicles up through model year 2005 
complying with the interim fleet average NOX standard is at 
least 50%.
    (vi) The provisions of paragraphs (c) (1), (2) and (3) of this 
section apply to flexible-fueled, dual fuel and multi-fuel interim non-
Tier 2 HLDT/MDPVs.
    (vii) For 2004 model year HLDT test groups whose model year 
commences before December 21, 2003, the manufacturer may exempt such 
HLDTs from compliance with any requirements applicable to interim non-
Tier 2 HLDTs, and such HLDTs must be produced in accordance with 
standards and requirements in Sec. Sec.86.1814-02 and 86.1815-02. Such 
HLDTs must also meet the refueling emission standards contained in 
paragraph (e)(3) of this section.
    (viii) For 2004 model year heavy-duty vehicles whose model year 
commences before December 21, 2003, the manufacturer may exempt such 
vehicles from compliance with any requirements applicable to interim 
non-Tier 2 MDPVs. Exempted vehicles will not be considered MDPVs and 
must be produced in accordance with standards and requirements in Sec.
86.099-10. Exempted vehicles are also exempted from refueling emission 
standards.
    (ix) For 2004 model year HLDT and MDPV test groups whose model year 
commences on or after December 21, 2003, the manufacturer must comply 
with all interim non-Tier 2 requirements in this section.
    (A) All such vehicles, but not more than 25% of the manufacturer's 
total sales of 2004 model year HLDT/MDPVs must meet the interim non-Tier 
2 fleet average NOX standard as described in paragraph 
(l)(3)(ii) of this section.
    (B) All such vehicles but not more than 40% of the manufacturer's 
2004 model year HLDT/MDPVs must comply with the refueling requirements 
in paragraph (e)(3) of this section.
    (x) Only those manufacturers that comply with the interim non-Tier 2 
FTP standards for all of their 2004 model year HLDTs and declare their 
intention to comply with the 2004 model year 25% phase-in requirement to 
the fleet average interim NOX standard for HLDTs or HLDT/
MDPVs of 0.20 g/mi described in paragraph (l) of this section may use 
the optional higher NMOG values for interim LDT4s certified to bin 10 
standards that are shown in Tables S04-1 and 2 of paragraph (c) of this 
section. Manufacturers must declare their intention to comply with the 
2004 model year 25% phase-in requirement in Part I of their HLDT 
certification applications.

[[Page 957]]

    (xi) Only those manufacturers that comply with the interim non-Tier 
2 FTP standards for all of their 2004 model year MDPVs, and declare 
their intention to comply with the 2004 model year 25% phase-in 
requirement to the fleet average interim NOX standard for 
MDPVs or HLDT/MDPVs of 0.20 g/mi described in paragraph (l) of this 
section may:
    (A) Use the exhaust emission standards of bin 11 in Tables S04-1 and 
S04-2 of paragraph (c) in this section for MDPVs through model year 
2008;
    (B) For diesel-fueled vehicles, certify the engines in such 
vehicles, through model year 2007, to provisions in this part 86 
applicable to diesel-fueled heavy-duty engines of the appropriate model 
year. Such diesel fueled vehicles must not be included in any count or 
determination of compliance with the phase-in requirements applicable to 
interim non-Tier 2 MDPVs; and
    (C) Use the optional higher NMOG values for interim LDT4s certified 
to bin 10 standards that are shown in Tables S04-1 and 2.
    (xii) Manufacturers electing to comply with the provisions of 
paragraph (l)(2)(xi) of this section must declare their intention to 
comply with the 2004 model year 25% phase-in requirement to the fleet 
average interim NOX standard for MDPVs or HLDT/MDPVs of 0.20 
g/mi in Part I of their MDPV certification applications.
    (xiii) Where diesel-fueled heavy-duty engines are used as permitted 
under paragraph (l)(2)(xi)(B) of this section, such engines must be 
treated as a separate averaging set--MDPV HDDEs--under the averaging, 
banking and trading provisions applicable to heavy-duty diesel engines. 
Only NOX credits generated by engine-certified diesel engines 
that are used in other MDPVs can be applied to these engines. 
Manufacturers wishing to average, bank or trade credits for MDPV HDDEs 
must comply with the requirements in this paragraph and with all 
requirements applicable to heavy-duty engine averaging, banking and 
trading in this part.
    (3) Fleet average NOX standards for interim non-Tier 2 
LDV/Ts and MDPVs. (i) Manufacturers must comply with a fleet average 
full useful life NOX standard for their interim non-Tier 2 
LDV/LLDTs, on an annual basis, of 0.30 grams per mile.
    (ii) Manufacturers must comply with a fleet average full useful life 
NOX standard for their interim non-Tier 2 HLDT/MDPVs, 
excluding those HLDTs and MDPVs not yet covered by the phase-in 
requirement described in paragraph (l)(2)(ii) of this section, on an 
annual basis, of 0.20 grams per mile.
    (iii) Manufacturers must determine their compliance with these 
interim fleet average NOX standards for each model year by 
separately computing the sales weighted average NOX level of 
all interim non-Tier 2 LDV/LLDTs and all interim non-Tier 2 HLDT/MDPVs 
(excluding those not yet phased in as described in paragraph (l)(2)(ii) 
of this section), using the methodology in Sec.86.1860.
    (iv) Manufacturers may generate, bank, average, trade and use 
interim non-Tier 2 NOX credits based on their NOX 
fleet average as determined under paragraph (l)(3)(iii) of this section. 
Unless waived or modified by the Administrator, the provisions of Sec.
86.1861 of this part apply to the generation, banking, averaging, 
trading and use of credits generated by interim non-Tier 2 vehicles. 
NOX credits generated by interim non-Tier 2 vehicles are not 
subject to any discount except as required by Sec.86.1861-04(e).
    (m) NMOG standards for diesel, flexible fueled and dual-fueled LDV/
Ts and MDPVs. (1) For diesel fueled LDV/Ts and MDPVs, the term ``NMOG'' 
in both the Tier 2 and interim non-Tier 2 standards means non-methane 
hydrocarbons.
    (2) Flexible-fueled and dual-fuel Tier 2 and interim non-Tier 2 
vehicles must be certified to NMOG exhaust emission standards both for 
operation on gasoline and on any alternate fuel they are designed to 
use. Manufacturers may measure NMHC in lieu of NMOG when flexible-fueled 
and dual-fuel vehicles are operated on gasoline, subject to the 
requirements of Sec.86.1810(p).
    (n) Requirements for vehicles with rechargeable energy storage 
systems. Manufacturers must measure emissions from hybrid electric 
vehicles (including plug-in hybrid electric vehicles) as described in 40 
CFR part 1066, subpart F,

[[Page 958]]

except that these procedures do not apply for plug-in hybrid electric 
vehicles during charge-depleting operation.
    (o) NMOG measurement. (1) Manufacturers must measure NMOG emissions 
using the procedures described in 40 CFR 1066.635.
    (2) Manufacturers must not apply reactivity adjustment factors 
(RAFs) to NMOG measurements. See Sec.86.1841.
    (p) In-use standards. (1) Table S04-10 of this paragraph (p) 
contains in-use emission standards applicable only to vehicles certified 
to the bins shown in the table. These standards apply to in-use testing 
performed by the manufacturer pursuant to regulations at Sec. Sec.
86.1845-01, 86.1845-04 and 86.1846-01 and to in-use testing performed by 
EPA. These standards do not apply to certification or Selective 
Enforcement Auditing.
    (2) These standards apply only to LDV/LLDTs produced up through the 
2008 model year, and HLDT/MDPVs produced up through the 2010 model year. 
These standards are subject to other limitations described in paragraph 
(p)(3) of this section.
    (3) For the first model year and also for the next model year after 
that, in which a test group of vehicles is certified to a bin of 
standards to which it has not previously been certified, the standards 
in Table S04-10 of this paragraph (p) apply for purposes of in-use 
testing only. The standards apply equally to all LDV/Ts and MDPVs 
subject to the model year limitation in paragraph (p)(2) of this 
section. Table S04-10 follows:

                                                    Table S04-10--In-use Compliance Standards (g/mi)

--------------------------------------------------------------------------------------------------------------------------------------------------------

    (4) For diesel vehicles certified to bin 10, separate in-use 
standards apply for NOX and PM emissions. These standards are 
determined by multiplying the applicable NOX and PM 
certification standards by factors of 1.2 and 1.35, respectively, and 
then rounding the result to one more decimal place than contained in the 
certification standard. The resultant standards do not apply for 
certification or selective enforcement auditing.
    (5) For diesel vehicles certified to bin 7 and bin 8 only in model 
years 2007 through 2009, a manufacturer may optionally comply with the 
bin 5 FTP PM standard shown in Table S04-1. For diesel vehicles choosing 
this option, separate in-use NOX standards apply at high 
altitude conditions as defined in Sec.86.1803-01. These standards are 
determined by multiplying the applicable NOX certification 
standards by a factor of 1.2. The resultant standards apply only in-use 
at high altitude conditions and do not apply for certification or 
selective enforcement auditing. A manufacturer choosing this option must 
certify such vehicles to the applicable FTP NOX and PM 
standards for a full useful life of 150,000 miles or 15 years, whichever 
occurs first. A manufacturer choosing this option would not be allowed 
to generate additional credits as described under Sec.86.1860-04 (g).
    (q) Hardship provision for small volume manufacturers. (1) A small 
volume manufacturer may apply for relief from any applicable final 
phase-in model year contained in this section. Relief will only be 
available to defer required compliance with a completely new set of 
standards, a fleet average NOX standard, and/or evaporative 
emission standard for 100% of affected vehicles for one model year. 
Thus, a small volume manufacturer that obtains relief may:
    (i) Defer 100% compliance with the fleet average NOX 
standard for interim LDV/LLDTs (0.30 g/mi) until 2005;

[[Page 959]]

    (ii) Defer 100% compliance with the evaporative emission standards 
and/or fleet average NOX standard for Tier 2 LDV/LLDTs (0.07 
g/mi) until 2008;
    (iii) Defer 100% compliance with the requirements that interim HLDTs 
and MDPVs comply with applicable emission standards shown in Tables S04-
1 and S04-2, until 2005;
    (iv) Defer 100% compliance with the fleet average NOX 
standard for interim HLDT/MDPVs (0.20 g/mi) until 2008; and
    (v) Defer 100% compliance with the evaporative emission standards 
and/or fleet average NOX standard for Tier 2 HLDT/MDPVs (0.07 
g/mi) until 2010.
    (vi) Defer compliance with the LDV/LLDT evaporative emissions 
standards in Table S09-1 of Sec.86.1811-09(e) until 2013, and defer 
100% compliance with the LDV/LLDT evaporative emissions standards in 
Table S09-2 of Sec.86.1811-09(e) until 2016. (The hardship relief may 
be extended one additional model year--two model years total.)
    (vii) Defer compliance with the HLDT/MDPV evaporative emissions 
standards in Table S09-1 of Sec.86.1811-09(e) until 2014, and defer 
100% compliance with the HLDT/MDPV evaporative emissions standards in 
Table S09-2 of Sec.86.1811-09(e) until 2016. (The hardship relief may 
be extended one additional model year--two model years total.)
    (viii) Defer 100% compliance with the LDV/LLDT cold temperature NMHC 
standards in Table S10-X of Sec.86.1811-10(g) until 2015. (The 
hardship relief may be extended one additional model year--two model 
years total.)
    (ix) Defer 100% compliance with the HLDT/MDPV cold temperature NMHC 
standards in Table S10-X of Sec.86.1811-10(g) until 2017. (The 
hardship relief may be extended one additional model year--two model 
years total.)
    (2) Applications for relief must be in writing and must:
    (i) Be submitted before the earliest date of noncompliance;
    (ii) Include evidence that the manufacturer will incur severe 
economic hardship if relief is not granted;
    (iii) Include evidence that the noncompliance will occur despite the 
best efforts of the manufacturer to comply; and
    (iv) Include evidence that the manufacturer has made every 
reasonable effort to purchase credits to address the noncompliance, 
where applicable.
    (r) NMOG standard adjustment for direct ozone reducing devices. (1) 
A manufacturer may obtain NMOG credit for use in certifying to the 
exhaust NMOG standards listed in paragraph (c) of this section and for 
use in complying with the in-use standards of paragraph (p) of this 
section, where applicable. This credit effectively allows the 
manufacturer to increase the exhaust NMOG emission standards listed in 
these paragraphs by the amount of the applicable credit. For example, if 
the applicable NMOG credit was 0.01 g/mi, and the vehicle was being 
certified in Bin 5, as described in Table S04-1 of paragraph (c) of this 
section, exhaust NMOG emissions must be no greater than 0.10 g/mi, as 
opposed to the normal NMOG certification standard of 0.09 g/mi in Bin 5.
    (2) The NMOG credit must be determined through a two-step process.
    (i) The first step must determine the ozone reduction potential of 
the direct ozone reducing device, the ozone reduction potential of 
exhaust NMOG reductions beyond Bin 5 of the Tier 2 standards, and the 
ratio of the two methods of reducing ambient ozone levels. The 
requirements for this step are described in paragraph (r)(3) of this 
section.
    (ii) The second step must demonstrate and certify the relevant 
performance characteristics of the specific ozone reducing device. The 
requirements for this step are described in paragraph (r)(4) of this 
section.
    (3) The ozone reduction potential of the direct ozone reducing 
device and the ozone reduction potential of exhaust NMOG reductions 
beyond Bin 5 of the Tier 2 standards must be estimated using procedures 
which are approved by the Administrator in advance. At a minimum:
    (i) The modeling must utilize an urban airshed model using up-to-
date chemical and meteorological simulation techniques;
    (ii) Four local areas must be modeled: New York City, Chicago, 
Atlanta and Houston;

[[Page 960]]

    (iii) The ozone episodes to be modeled must meet the selection 
criteria established by EPA for State ozone SIPs;
    (iv) Photochemical and dispersion modeling must follow that used by 
EPA to project the ozone impacts of this rule, or its equivalent;
    (v) Emission projections must be made for calendar year 2007 and be 
consistent with those used by EPA in support of this final rule, or 
reflect updates approved by EPA;
    (vi) Baseline emissions (emissions prior to use of the direct ozone 
reducing device or the VOC emission reductions) must include the 
benefits of the Tier 2 emission and sulfur standards; as well as all 
other emission controls assumed in EPA's ozone modeling of the benefits 
of the Tier 2 and sulfur standards, as described in the Final Regulatory 
Impact Analysis to the Tier 2 and Sulfur Rule;
    (vii) The ozone benefit of the direct ozone reducing device must 
assume a radiator area of 0.29 square meters, an air flow velocity 
through the radiator of 40% of vehicle speed, and an ozone reduction 
efficiency of 80%, or other values as approved by the Administrator;
    (viii) The ozone level of the air entering the direct ozone reducing 
device must be assumed to be 40% less than that existing in the grid 
cell where the vehicle is located;
    (ix) The ozone benefit of VOC emission reductions must be modeled by 
assuming that all Tier 2 LDVs, LDTs and MDPVs meet an exhaust NMOG 
standard of 0.055 g/mi or lower instead of a 0.09 g/mi NMOG standard;
    (x) The ozone reducing device must be assumed to be present on all 
of the Tier 2 LDVs, LDTs and MDPVs modeled as meeting the more stringent 
NMOG standard described in paragraph (r)(3)(ix) of this section;
    (xi) The relationship between changes in exhaust NMOG emission 
standards and in-use VOC emissions must be determined sufficiently far 
in the future to ensure that the change in ozone being modeled is 
sufficiently large to allow comparison with the impact of the ozone 
reducing device;
    (xii) LDV, LDT and MDPV emissions must be modeled using the updated 
Tier 2 emission model developed by EPA as part of the Tier 2 rulemaking 
(available from EPA upon request) or MOBILE6, once this model is 
available;
    (xiii) The ozone benefit of the direct ozone reducing device must be 
the reduction in the peak one-hour ozone level anywhere in the modeled 
region on the day when ozone is at its highest;
    (xiv) The NMOG credit in each local area must be the reduction in 
peak one hour ozone associated with use of the direct ozone reducing 
device divided by the reduction in peak one hour ozone associated with 
the more stringent exhaust NMOG emission standard multiplied by the 
reduction the exhaust NMOG standard (in g/mi) modeled in paragraph 
(r)(3)(ix) of this section; and
    (xv) The NMOG credit applicable to the generic direct ozone reducing 
device modeled in paragraph (r)(3)(vii) of this section must be 
determined by arithmetically averaging the NMOG credit determined in 
paragraph (r)(3)(xiv) of this section for each of the four local areas.
    (4) The manufacturer must submit data, using procedures which have 
been approved by the Administrator in advance, that demonstrate the 
following aspects of the device being certified:
    (i) The air flowrate through the device as a function of vehicle 
speed;
    (ii) The ozone reduction efficiency of the device over the useful 
life of the vehicle for a range of vehicle speeds and ozone levels;
    (iii) The method through which the onboard diagnostic system will 
detect improper performance.
    (5) The NMOG credit for the specific application of this technology 
tested under the provisions of paragraph (r)(4) of this section is the 
four-area NMOG credit determined in paragraph (r)(3)(xv) of this section 
scaled based on the performance of the specific application tested under 
the provisions of paragraph (r)(4) of this section relative to those 
assumed in paragraph (r)(3)(vii) of this section. This scaling must 
assume a linear relationship between the NMOG credit and three aspects 
of the direct ozone reducing device: radiator area, average air flow 
through the radiator relative to vehicle speed, and ozone reduction 
efficiency and the NMOG credit. The NMOG credit must be rounded to the 
nearest 0.001

[[Page 961]]

g/mi. For example, if the NMOG credit determined in paragraph (r)(3)(xv) 
of this section was 0.01 g/mi and the specific direct ozone reducing 
device being certified had an area of 0.20 square meters, an air flow 
velocity of 30% of vehicle speed and an ozone reducing efficiency of 
70%, and the generic ozone reducing device simulated in the ozone model 
under paragraph (r)(3)(vii) of this section had an area of 0.29 square 
meters, an air flow velocity of 40% of vehicle speed and an ozone 
reducing efficiency of 80%, the NMOG credit applicable to the specific 
device being certified would be:

0.01 g/mi * (0.20/0.29) * (30%/40%) * 70%/80%) = 0.005
    (s) Manufacturers may request to group heavy-duty vehicles into the 
same test group as other vehicles subject to more stringent standards, 
so long as all vehicles in the test group meet the most stringent 
standards applicable to any vehicle within that test group, as provided 
at Sec.86.1827-1(a)(5) and (d)(4).

Sec.86.1811-09  Emission standards for light-duty vehicles, 
light-duty trucks and medium-duty passenger vehicles.

    Section 86.1811-09 includes text that specifies requirements that 
differ from Sec.86.1811-04. Where a paragraph in Sec.86.1811-04 is 
identical and applicable to Sec.86.1811-09, this may be indicated by 
specifying the corresponding paragraph and the statement ``[Reserved]. 
For guidance see Sec.86.1811-04.'' Where a corresponding paragraph of 
Sec.86.1811-04 is not applicable, this is indicated by the statement 
``[Reserved]''
    (a) Applicability. (1) This section contains regulations 
implementing emission standards for all LDVs, LDTs and MDPVs. This 
section applies to 2009 and later model year LDVs, LDTs and MDPVs fueled 
by gasoline, diesel, methanol, ethanol, natural gas and liquefied 
petroleum gas fuels, except as noted. Additionally, this section applies 
to hybrid electric vehicles (HEVs) and zero emission vehicles (ZEVs). 
Unless otherwise specified, multi-fueled vehicles must comply with all 
requirements established for each consumed fuel.
    (2) through (4) [Reserved]. For guidance see Sec.86.1811-04.
    (5) The exhaust emission standards and evaporative emission 
standards of this section apply equally to certification and in-use 
LDVs, LDTs and MDPVs, unless otherwise specified. See paragraph (t) of 
this section for interim evaporative emission in-use standards that are 
different than the certification evaporative emission standards 
specified in paragraph (e) of this section.
    (b) through (d) [Reserved]. For guidance see Sec.86.1811-04.
    (e) Evaporative emission standards. Evaporative emissions from 
gasoline-fueled, natural gas-fueled, liquefied petroleum gas-fueled, 
ethanol-fueled and methanol-fueled vehicles must not exceed the 
standards in this paragraph (e) at low altitude conditions. The 
evaporative emission standards specified in Sec.86.1811-04(e)(1) 
continue to apply at high altitude conditions. The standards apply 
equally to certification and in-use vehicles.
    (1) Diurnal-plus-hot soak evaporative hydrocarbon standards. (i) 
Hydrocarbons for LDV/LLDTs, HLDTs and MDPVs that are gasoline-fueled, 
dedicated natural gas-fueled, dedicated liquefied petroleum gas-fueled, 
dedicated ethanol-fueled, dedicated methanol-fueled and multi-fueled 
vehicles when operating on gasoline must not exceed the diurnal plus hot 
soak standards shown in Table S09-1 for the full three diurnal test 
sequence and for the supplemental two diurnal test sequence. The 
standards apply equally to certification and in-use vehicles, except as 
otherwise specified in paragraph (t) of this section. Table S09-1

manufacturers must comply with the phase-in requirements in Table S09-3 
of this paragraph for the evaporative emission requirements specified in 
Table S09-2 of this section. Phase-in schedules are grouped together for 
LDV/LLDTs and HLDT/MDPVs. These requirements specify the minimum 
percentage of the manufacturer's LDV/LLDT/HLDT/MDPV 50-State sales, by 
model year, that must meet the requirements for their full useful lives.

    (2) through (6) [Reserved]. For guidance see Sec.86.1811-04.
    (7) In cases where vehicles are certified to evaporative emission 
standards in Tables S09-1 and S09-2 of this section, the Administrator 
may accept evaporative emissions data for low altitude testing in 
accordance with California test conditions and test procedures (in lieu 
of the evaporative emission test condition and test procedure 
requirements of subpart B of this part).
    (f) through (s) [Reserved]. For guidance see Sec.86.1811-04.
    (t) Evaporative emission in-use standards. (1) For LDVs and LLDTs 
certified prior to the 2012 model year, the Tier 2 LDV/LLDT evaporative 
emissions standards in Table S04-3 of Sec.86.1811-04(e) shall apply to 
in-use vehicles for only the first three model years after an 
evaporative family is first certified to the LDV/LLDT evaporative 
emission standards in Table S09-1 of paragraph (e) of this section, as 
shown in Table S09-4. For example, evaporative families first certified 
to the LDV/LLDT standards in Table S09-1 in the 2011 model year must 
meet the Tier 2 LDV/LLDT evaporative emission standards (Table S04-3) 
in-use for 2011, 2012, and 2013 model year vehicles (applying Tier 2 
standards in-use is limited to the first three years after introduction 
of a vehicle).

    (2) For HLDTs and MDPVs certified prior to the 2013 model year, the 
Tier 2 HLDT/MDPV evaporative emissions standards in Table S04-3 of Sec.
86.1811-04(e) shall apply to in-use vehicles for only the first three 
model years after an evaporative family is first certified to the HLDT/
MDPV evaporative emission standards in Table S09-1 of paragraph (e) of 
this section, as shown in Table S09-5. For example, evaporative families 
first certified to the HLDT/MDPV standards in Table S09-1 in the 2012 
model year must meet the Tier 2 HLDT/MDPV evaporative emission standards 
(Table S04-3) in-use for 2012, 2013, and 2014 model year vehicles 
(applying Tier 2 standards in-use is limited to the first three years 
after introduction of a vehicle).

Sec.86.1811-10  Emission standards for light-duty vehicles, 
light-duty trucks and medium-duty passenger vehicles.

    Section 86.1811-10 includes text that specifies requirements that 
differ from Sec. Sec.86.1811-04 and 86.1811-09. Where a paragraph in 
Sec.86.1811-04 or Sec.86.1811-09 is identical and applicable to 
Sec.86.1811-10, this may be indicated by specifying the corresponding 
paragraph and the statement ``[Reserved]. For guidance see Sec.
86.1811-04'' or ``[Reserved]. For guidance see Sec.86.1811-09.'' Where 
a corresponding paragraph of Sec.86.1811-04 or Sec.86.1811-09 is not 
applicable, this is indicated by the statement ``[Reserved]''
    (a) [Reserved]. For guidance see Sec.86.1811-09.
    (b) through (d) [Reserved]. For guidance see Sec.86.1811-04.
    (e) [Reserved]. For guidance see Sec.86.1811-09.
    (f) [Reserved]. For guidance see Sec.86.1811-04.
    (g) Cold temperature exhaust emission standards. (1) Cold 
temperature CO standards. These cold temperature CO standards are 
applicable only to gasoline fueled LDV/Ts and MDPVs. Cold temperature CO 
exhaust emission standards apply over a useful life of 50,000 miles or 5 
years (whichever occurs first) as follows:
    (i) For LDVs and LDT1s, the standard is 10.0 grams per mile CO.
    (ii) For LDT2s, LDT3s and LDT4s, and MDPVs, the standard is 12.5 
grams per mile CO.
    (iii) These standards do not apply to interim non-Tier 2 MDPVs.
    (2) Cold temperature NMHC standards. Full useful life fleet average 
cold temperature NMHC standards are applicable only to gasoline fueled 
LDV/LLDTs and HLDT/MDPVs, and apply equally to certification and in-use 
except as otherwise specified in paragraph (u) of this section for in-
use standards for applicable phase-in models. Testing with other fuels 
such as E85, or testing on diesel vehicles, is not required. Multi-fuel, 
bi-fuel or dual-fuel vehicles must comply with requirements using 
gasoline only. For LDV/LLDTs, the useful life is 120,000 miles or 10 
years, whichever comes first. For HLDT/MDPVs, the useful life is 120,000 
miles or 11 years, whichever comes first. There is not an intermediate 
useful life standard for cold temperature NMHC standards.
    (i) The standards are shown in the following table:

    (ii) The manufacturer must calculate its fleet average cold 
temperature NMHC emission level(s) as described in Sec.86.1864-10(m).
    (iii) During a phase-in year, the manufacturer must comply with the 
fleet average standards for the required phase-in percentage for that 
year as specified in paragraph (g)(3) of this section, or for the 
alternate phase-in percentage as permitted under paragraph (g)(4) of 
this section.
    (iv) For model years prior to 2010 (LDV/LLDTs) and 2012 (HLDT/
MDPVs), where the manufacturer desires to bank early NMHC credits as 
permitted under Sec.86.1864-10(o)(5), the manufacturer must achieve a 
fleet average standard below the applicable standard. Manufacturers must 
determine compliance with the cold temperature NMHC fleet average 
standard according to Sec.86.1864-10(o).
    (3) Phase-in of the cold temperature NMHC standards. Except as 
permitted in Sec.86.1811-04(k)(5)(vi) and (vii) regarding small volume 
manufacturers, manufacturers must comply with the phase-in requirements 
in Tables S10-2 and S10-3. Separate phase-in schedules are provided for 
LDV/LLDTs and for HLDT/MDPVs. These requirements specify the minimum 
percentage of the manufacturer's LDV/LLDT and HLDT/MDPV 50-State sales, 
by model year, that must meet the fleet average cold temperature NMHC 
standard for their full useful lives. LDVs and LLDTs must be grouped 
together to determine compliance with these phase-in requirements, and 
HLDTs and MDPVs must also be grouped together to determine compliance 
with these phase-in requirements. Tables S10-2 and S10-3 follow:

    (4) Alternate phase-in schedules for cold temperature NMHC 
standards. (i) Manufacturers may apply for alternate phase-in schedules 
that would still result in 100% phase-in by 2013 and 2015, respectively, 
for LDV/LLDTs and HLDT/MDPVs. An alternate phase-in schedule submitted 
by a manufacturer is subject to EPA approval. The alternate phase-in 
will not be used to delay full implementation past the last year of the 
primary phase-in schedule (2013 for LDV/LLDTs, 2015 for HLDT/MDPVs). An 
alternate phase-in schedule will be acceptable if it satisfies the 
following conditions (where API = Anticipated Phase-In percentage for 
the referenced model year):
    LDV/LLDTs:

(6 x API2008) + (5 x API2009) + (4 x 
API2010) + (3 x API2011) + (2 x 
API2012) + (1 x API2013) = 500%, and (6 
x API2008) + (5 x API2009) + (4 x 
API2010) = 100%

    HLDT/MDPVs:

(6 x API2010) + (5 x API2011) + (4 x 
API2012) + (3 x API2013) + (2 x 
API2014) + (1 x API2015) = 500%, and (6 
x API2010) + (5 x API2011) + (4 x 
API2012) = 100%,
     or

(6 x API2010) + (5 x API2011) + (4 x 
API2012) + (3 x API2013) + (2 x 
API2014) + (1 x API2015) = 600%

    (ii)(A) For LDV/LLDTs, if the sum of products in paragraph (g)(4)(i) 
of this section is greater than or equal to

[[Page 965]]

500%, which is the sum of products from the primary phase-in schedule (4 
x 25% + 3 x 50% + 2 x 75% + 1 x 100% = 500%), then the alternate phase-
in schedule is acceptable, except as prohibited in paragraphs (g)(4)(i) 
and (iii) of this section. In addition, manufacturers electing to use an 
alternate phase-in schedule for compliance with the cold temperature 
NMHC exhaust emission standards must ensure that the sum of products is 
at least 100% for model years 2010 and earlier for LDV/LLDTs. For 
example, a phase-in schedule for LDV/LLDTs of 5/10/10/45/80/100 that 
begins in 2008 would calculate as (6 x 5%) + (5 x 10%) + (4 x 10%) = 
120% and would be acceptable for 2008-2010. The full phase-in would 
calculate as (6 x 5%) + (5 x 10%) + (4 x 10%) + (3 x 45%) + (2 x 80%) + 
(1 x 100%) = 515% and would be acceptable for 2008-2013.
    (B) For HLDT/MDPVs, if the sum of products in paragraph (g)(4)(i) of 
this section is greater than or equal to 500%, which is the sum of 
products from the primary phase-in schedule (4 x 25% + 3 x 50% + 2 x 75% 
+ 1 x 100% = 500%), then the alternate phase-in schedule is acceptable, 
except as prohibited in paragraphs (g)(4)(i) and (iii) of this section. 
In addition, manufacturers electing to use an alternate phase-in 
schedule for compliance with the cold temperature NMHC exhaust emission 
standards must ensure that the sum of products is at least 100% for 
model years 2012 and earlier for HLDT/MDPVs. Alternately, if the sum of 
products is greater than or equal to 600%, then the alternate phase-in 
schedule is acceptable, except as prohibited in paragraphs (g)(4)(i) and 
(iii) of this section. If the sum of products is greater than or equal 
to 600%, then there are no requirements on the sum of products for model 
years 2012 and earlier.
    (iii) Under an alternate phase-in schedule, the projected phase-in 
percentage is not binding for a given model year, provided the sums of 
the actual phase-in percentages that occur meet the appropriate total 
sums as required in the equations of paragraph (g)(4)(i) of this 
section, and provided that 100% actual compliance is reached for the 
appropriate model year, either 2013 for LDV/LLDTs or 2015 for HLDT/
MDPVs.
    (5) Manufacturers must determine compliance with required phase-in 
schedules as follows:
    (i) Manufacturers must submit information showing compliance with 
all phase-in requirements of this section with their Part I applications 
as required by Sec.86.1844(d)(13).
    (ii) A manufacturer electing to use any alternate phase-in schedule 
permitted under this section must provide in its Application for 
Certification for the first year in which it intends to use such a 
schedule, and in each succeeding year during the phase-in, the intended 
phase-in percentages for that model year and the remaining phase-in 
years along with the intended final sum of those percentages as 
described in paragraph (g)(4)(i) of this section. This information may 
be included with the information required under Sec.86.1844-01(d)(13). 
In its year end annual reports, as required under Sec.86.1844-
01(e)(4), the manufacturer must include sufficient information so that 
the Administrator can verify compliance with the alternate phase-in 
schedule established under paragraph (g)(4)(i) of this section.
    (6)(i) Sales percentages for the purpose of determining compliance 
with the phase-in of the cold temperature NMHC requirements must be 
based upon projected 50-State sales of LDV/LLDTs and HLDT/MDPVs of the 
applicable model year by the manufacturer to the point of first sale. 
Such sales percentages must be rounded to the nearest 0.1 percent.
    (ii) Alternatively, the manufacturer may petition the Administrator 
to allow actual volume produced for U.S. sales to be used in lieu of 
projected U.S. sales for purposes of determining compliance with the 
phase-in percentage requirements under this section. The manufacturer 
must submit its petition within 30 days of the end of the model year. 
For EPA to approve the use of actual volume produced for U.S. sales, the 
manufacturer must establish to the satisfaction of the Administrator, 
that actual production volume is functionally equivalent to actual sales 
volume of LDV/LLDTs and HLDT/MDPVs sold in all 50 U.S. States.

    (t) [Reserved]. For guidance see Sec.86.1811-09.
    (u) Cold temperature NMHC exhaust emission in-use standards for 
applicable phase-in models. An interim full useful life in-use 
compliance standard is calculated by adding 0.1 g/mi to the FEL to which 
each test group is newly certified, and applies to that test group only 
for the model years shown in Tables S10-4 and S10-5. Otherwise, the in-
use standard is the certification standard from paragraph (g)(2) of this 
section. The standards apply for purposes of in-use testing only and 
does not apply to certification or Selective Enforcement Auditing.

[72 FR 8564, Feb. 26, 2007]



Sec.86.1811-17  Exhaust emission standards for light-duty vehicles, 
light-duty trucks and medium-duty passenger vehicles.

    (a) Applicability and general provisions. This section describes 
exhaust emission standards that apply for model year 2017 and later 
light-duty vehicles, light-duty trucks, and medium-duty passenger 
vehicles. MDPVs are subject to all the same emission standards and 
certification provisions that apply to LDT4. Some of the provisions of 
this section also apply to heavy-duty vehicles as specified in Sec.
86.1816. See Sec.86.1818 for greenhouse gas emission standards. See 
Sec.86.1813 for evaporative and refueling emission standards. This 
section may apply to vehicles from model years earlier than 2017 as 
specified in paragraph (b)(11) of this section.
    (b) Tier 3 exhaust emission standards. Exhaust emissions may not 
exceed the Tier 3 exhaust emission standards, as follows:
    (1) Measure emissions using the chassis dynamometer procedures of 40 
CFR part 1066, as follows:
    (i) Establish appropriate load settings based on loaded vehicle 
weight (see Sec.86.1803).
    (ii) Use appropriate driving schedules. Measurements involve testing 
over multiple driving schedules. The Federal Test Procedure (FTP) is 
based on testing with the Urban Dynamometer Driving Schedule (UDDS). The 
Supplemental Federal Test Procedure (SFTP) involves testing with the 
UDDS, the US06 driving schedule, and the SC03 driving schedule. See 40 
CFR 1066.801 for further information on these test cycles.
    (iii) Calculate SFTP emissions as a composite of test results over 
the driving schedules identified in paragraph (b)(1)(ii) of this section 
based on the following calculation:

SFTP (g/mi) = 0.35 x FTP + 0.28 x US06 + 0.37 x SC03

    (A) For test vehicles that do not have air conditioning, you may 
omit SC03 testing. To calculate composite SFTP emissions for such 
vehicles, use FTP emission results to substitute for the SC03 value in 
the equation.
    (B) You may also use FTP emission results to substitute for the SC03 
value

[[Page 967]]

in the equation for the types of vehicles identified in 40 CFR 600.115 
that automatically qualify for the derived 5-cycle method for 
determining fuel economy label values. Such vehicles remain subject to 
the SFTP standard when tested over the SC03 driving schedule. Other 
vehicles remain subject to the litmus-test provisions in 40 CFR 600.115.
    (iv) Use E10 test fuel as required in Sec.86.113, except as 
specified in this section.
    (v) Hydrocarbon emission standards are expressed as NMOG; however, 
for certain vehicles you may measure exhaust emissions based on 
nonmethane hydrocarbon instead of NMOG as described in 40 CFR 1066.635.
    (vi) Measure emissions from hybrid electric vehicles (including 
plug-in hybrid electric vehicles) as described in 40 CFR part 1066, 
subpart F, except that these procedures do not apply for plug-in hybrid 
electric vehicles during charge-depleting operation.
    (2) Table 1 of this section describes fully phased-in Tier 3 
standards that apply as specified in this paragraph (b) for the 
identified driving schedules. The FTP standards for NMOG + 
NOX apply on a fleet-average basis using discrete bin 
standards as described in paragraph (b)(4) of this section. The bin 
standards include additional emission standards for high-altitude 
testing and for CO emissions when testing over the FTP driving schedule. 
The SFTP standards for NMOG + NOX apply on a fleet-average 
basis as described in paragraph (b)(5) of this section. Table 1 follows:

\1\ The fleet-average FTP emission standard for NMOG + NOX is 0.026 g/mile for LDV and LDT1 test groups
  certified to standards based on a useful life of 120,000 miles or 10 years in a given model year.

    (3) The FTP standards specified in this section apply for testing at 
low-altitude conditions and high-altitude conditions as specified in 
paragraph (b)(4) of this section. The SFTP standards specified in 
paragraph (b)(2) of this section apply only for testing at low-altitude 
conditions.
    (4) The FTP emission standard for NMOG + NOX is based on 
a fleet average for a given model year. You must specify a family 
emission limit (FEL) for each test group. The FEL serves as the emission 
standard for the test group with respect to all required FTP testing. 
Calculate your fleet-average emission level as described in Sec.
86.1860 based on the FEL that applies for low-altitude testing to show 
that you meet the specified standard. For multi-fueled vehicles, 
calculate fleet-average emission levels based only on emission levels 
for testing with gasoline or diesel fuel. You may generate emission 
credits for banking and trading and you may use banked or traded credits 
as described in Sec.86.1861 for demonstrating compliance with the FTP 
emission standard for NMOG + NOX. You comply with the 
emission standard for a given model year if you have enough credits to 
show that your fleet-average emission level is at or below the 
applicable standard. You may exchange FTP credits between or among any 
test groups subject to standards under this section. You may not 
exchange FTP and SFTP credits.
    (i) Specify one of the identified values from Table 2 of this 
section as the FEL for demonstrating that your fleet-average emission 
level complies with the FTP emission standard for NMOG + NOX 
under low-altitude conditions. These FEL values define emission bins 
that also determine corresponding emission standards for NMOG + 
NOX emissions under high-altitude conditions, and for CO 
emissions, as follows:

    (ii) Manufacturers earn a compliance credit of 0.005 g/mile NMOG + 
NOX for vehicles that are certified for a useful life of 
150,000 miles or 15 years and that are covered by an extended warranty 
over the same period for all components whose failure triggers MIL 
illumination. Manufacturers may apply the compliance credit as follows:
    (A) You may reduce your official FTP emission result for 
certification by the amount of the compliance credit if that allows you 
to certify to a more stringent bin. In that case, you may use the more 
stringent bin standard for calculating the fleet-average NMOG + 
NOX emission level. For any compliance testing with these 
vehicles, the applicable FTP bin standard for NMOG + NOX is 
higher than the specified bin standard by the amount of the compliance 
credit. For example, if the official FTP emission result for NMOG + 
NOX is 0.052 g/mile, this qualifies for an FEL of 0.050 g/
mile for calculating the fleet average and the vehicle is subject to an 
FTP bin standard of 0.055 g/mile.
    (B) If the amount of the compliance credit does not allow you to 
certify to a more stringent bin, calculate the fleet-average NMOG + 
NOX emission level using an FEL for these vehicles that is 
smaller than the bin standard by the amount of the compliance credit. 
For any compliance testing with these vehicles, the specified bin 
standard applies. For example, if the official FTP emission result for 
NMOG + NOX is 0.038 g/mile, calculate the fleet-average NMOG 
+ NOX emission level by specifying an FEL of 0.045 g/mile; 
these vehicles are subject to the specified FTP bin standard of 0.050 g/
mile.
    (iii) If you qualify for a compliance credit for direct ozone 
reduction under the LEV III program, you may apply the compliance credit 
approved for California vehicles as described in paragraphs 
(b)(4)(ii)(A) and (B) of this section.
    (iv) You may combine the adjustments in paragraphs (b)(4)(ii) and 
(iii) of this section if you qualify for them separately.
    (5) The SFTP emission standard for NMOG + NOX is also 
based on a fleet average in a given model year. You must specify FELs as 
described in paragraph (b)(4) of this section and calculate a fleet-
average emission level to show that you meet the SFTP emission standard 
for NMOG + NOX, except that you may specify FELs in any even 
increment of 0.010 g/mile up to a maximum value of 0.180 g/mile. You may 
generate emission credits for banking and trading and you may use banked 
or traded credits as described in Sec.86.1861 for demonstrating 
compliance with the SFTP emission standard for NMOG + NOX. 
You comply with the emission standard for a given model year if you have 
enough credits to show that your fleet-average emission level is at or 
below the applicable standard. You may exchange SFTP credits between or 
among any test groups subject to standards under this section. You may 
not exchange FTP and SFTP credits. The SFTP standards described in this 
section apply only for testing at low-altitude conditions.
    (6) The full Tier 3 program includes new emission standards for NMOG 
+ NOX, PM, CO, and formaldehyde; it also includes measurement 
with a new test fuel and a longer useful life (for some vehicles). 
Vehicles meeting all these requirements are considered Final Tier 3 
vehicles. Vehicles that do not meet

[[Page 969]]

all the Tier 3 requirements are considered Interim Tier 3 vehicles. 
Paragraphs (b)(7) through (13) of this section describe how to comply 
with standards during a phase-in period.
    (7) The Tier 3 PM standards phase in over several years. The 
following provisions describe the primary approach for phasing in the 
Tier 3 PM standards:
    (i) You must meet the FTP and the US06 PM standards with 20, 20, 40, 
70, and 100 percent of your projected nationwide sales of all vehicles 
subject to this section in model years 2017 through 2021, respectively. 
In model years 2017 and 2018, an interim US06 PM standard of 0.010 g/
mile applies. Each vehicle meeting the Tier 3 FTP standard for PM must 
also meet the Tier 3 US06 standard for PM. In model year 2017, the 
phase-in requirement applies only for vehicles at or below 6,000 pounds 
GVWR; however, you may meet an alternative phase-in requirement of 10 
percent in model year 2017 based on your full production of vehicles 
subject to standards under this section.
    (ii) You may disregard the phase-in percentages specified in 
paragraph (b)(7)(i) of this section if you instead comply with an 
indexed PM phase-in schedule as described in this paragraph (b)(7)(ii). 
To do this, you must notify us of your intent before January 1, 2017, 
and include a detailed plan for complying with the indexed phase-in 
schedule. You comply with the indexed phase-in schedule by calculating a 
PM phase-in index at or above 540 using the following equation for model 
years 2017 through 2021:

PM phase-in index = 5 [middot] APP2017 + 4 [middot] 
APP2018 + 3 [middot] APP2019 + 2 [middot] 
APP2020 + APP2021

Where:

APP = The phase-in percentage of vehicles meeting the Tier 3 PM 
          standards for the indicated model year, based on actual sales, 
          as described in paragraph (b)(7)(i) of this section.

    (iii) Vehicles meeting the Tier 3 PM standards must meet those 
standards over the useful life as specified in Sec.86.1805. Note that 
Interim Tier 3 vehicles may have different useful life values for PM 
emission standards than for other emission standards.
    (iv) Any vehicles not included for demonstrating compliance with the 
Tier 3 PM phase-in requirement must instead comply with an FTP emission 
standard for PM of 0.010 g/mile, and a composite SFTP emission standard 
for PM of 0.070 g/mile.
    (v) Measure PM emissions from all vehicles using the same test fuel 
specified in paragraph (b)(8) of this section for measuring NMOG + 
NOX emissions.
    (vi) You may certify Interim Tier 3 vehicles based on carryover 
data.
    (vii) You may use the alternative phase-in provisions described in 
paragraph (b)(9) of this section to transition to the Tier 3 exhaust 
emission standards on a different schedule.
    (8) The following provisions describe the primary approach for 
phasing in the Tier 3 standards other than PM in 2025 and earlier model 
years:
    (i) FTP phase-in. The fleet-average FTP emission standard for NMOG + 
NOX phases in over several years as described in this 
paragraph (b)(8)(i). You must identify FELs as described in paragraph 
(b)(4) of this section and calculate a fleet-average emission level to 
show that you meet the FTP emission standard for NMOG + NOX 
that applies for each model year. For model year 2017, do not include 
vehicles above 6,000 pounds GVWR. Through model year 2019, you may also 
certify to transitional Bin 85 or Bin 110 standards, which consist of 
all-altitude FTP emission standards for NMOG + NOX of 0.085 
or 0.110 g/mile, respectively; additional FTP standards for PM, CO, and 
formaldehyde apply as specified in this section for vehicles certified 
to Bin 125 standards. Fleet-average FTP emission standards decrease 
through the phase-in period as shown in the following table:

\1\ Vehicles certified to standards based on a useful life of 120,000 miles may comply based on the fleet-
  average standard specified for 150,000 mile useful life in certain circumstances as specified in paragraph
  (b)(8)(iii)(A) of this section.
\2\ HLDT and MDPV must meet the Tier 3 standards starting with model year 2018.

    (ii) SFTP phase-in. The fleet-average SFTP emission standard for 
NMOG + NOX phases in over several years as described in this 
paragraph (b)(8)(ii). You must identify FELs as described in paragraph 
(b)(5) of this section and calculate a fleet-average emission level to 
show that you meet the SFTP emission standard for NMOG + NOX 
that applies for each model year.
    (A) Calculate the fleet-average emission level together for all your 
light-duty vehicles and light-duty trucks, except for those certified 
using the provisions of paragraph (b)(8)(ii)(C) of this section. For 
model year 2017, do not include vehicles above 6,000 pounds GVWR (in the 
numerator or denominator).
    (B) Fleet-average SFTP emission standards decrease through the 
phase-in period as shown in the following table:

\1\ HLDT and MDPV must meet the Tier 3 standards starting with model
  year 2018.

    (C) You may use the SFTP stand-alone option specified in 13 CCR 
1961.2 (a)(7)(A)1 of the LEV III program to demonstrate compliance with 
EPA's SFTP standards. Do not include any such test groups when 
demonstrating compliance with the phased-in fleet-average SFTP standards 
specified in this paragraph (b)(8)(ii). Note that this option is not 
available for vehicles certified to the transitional bins described in 
paragraph (b)(8)(i) of this section.
    (iii) Interim provisions. (A) For vehicles certified to bins higher 
than Bin 70 under this section through model year 2019, the Tier 2 
useful life period applies as specified in Sec.86.1805-12 for all 
criteria pollutants other than PM. However, LDV and LDT1 test groups 
certified to bin standards above Bin 70 through model year 2019 may be 
included in the same averaging set with vehicles meeting standards over 
a 150,000 mile useful life, notwithstanding the provisions of Sec.
86.1861-17(b)(1)(iii). Any such vehicles you include in the averaging 
set for 150,000 mile useful life are also subject to the fleet-average 
NMOG + NOX standard specified for 150,000 mile useful life; 
similarly, any such vehicles you include in the averaging set for 
120,000 mile useful life are also subject to the fleet-average NMOG + 
NOX standard specified for 120,000 mile useful life.
    (B) You may use the E0 test fuel specified in Sec.86.113 through 
model year 2019 for gasoline-fueled vehicles certified to bins higher 
than Bin 70. You may not certify these vehicles using carryover data 
after model year 2019.
    (C) Vehicles must comply with the Tier 2 SFTP emission standards for 
NMHC + NOX and CO for 4,000-mile

[[Page 971]]

testing that are specified in Sec.86.1811-04(f)(1) if they are 
certified to transitional Bin 85 or Bin 110 standards, or if they are 
certified based on a fuel without ethanol, or if they are not certified 
to the Tier 3 p.m. standard. Note that these standards apply under this 
section for alternative fueled vehicles, for flexible fueled vehicles 
when operated on a fuel other than gasoline or diesel fuel, and for 
MDPVs, even though these vehicles were not subject to the SFTP standards 
in the Tier 2 program.
    (iv) You may use the alternative phase-in provisions described in 
paragraph (b)(9) of this section to transition to the Tier 3 exhaust 
emission standards on a different schedule.
    (9) This paragraph (b)(9) describes an alternative approach to 
phasing in the Tier 3 emission standards for vehicles above 6,000 pounds 
GVWR. If you choose this approach, you must phase in the Tier 3 
standards for all your vehicles above 6,000 pounds GVWR that are subject 
to this section according to this schedule. Under this alternative 
phase-in, you must meet the fully phased-in standards specified in this 
paragraph (b) with 40, 70, and 100 percent of your projected nationwide 
sales of all vehicles above 6,000 pounds GVWR that are subject to this 
section in model years 2019 through 2021, respectively. Any vehicles not 
subject to Tier 3 standards during the phase-in period must continue to 
comply with the Tier 2 standards in Sec.86.1811-04(c) and (f), 
including the Tier 2 SFTP emission standards for NMHC + NOX 
and CO for 4,000-mile testing as specified in Sec.86.1811-04(f)(1). 
Vehicles subject to Tier 2 standards under this paragraph (b)(9) are 
subject to the useful life provisions in Sec.86.1805-12 relative to 
exhaust emission standards. Each vehicle counting toward the phase-in 
percentage under this paragraph (b)(9) must meet all the standards that 
apply throughout the useful life as specified in Sec.86.1805-17, and 
must use the Tier 3 test fuel specified in Sec.86.113-15. The 
following exceptions and special provisions apply under this paragraph 
(b)(9):
    (i) For model year 2019, you may exclude from the phase-in 
calculation any test groups with vehicles above 6,000 pounds GVWR that 
have a Job 1 date on or before March 3, 2018 (see 40 CFR 85.2304).
    (ii) The FTP and SFTP emission standards for NMOG + NOX 
are fleet-average standards. Calculate your fleet-average values based 
on all the vehicles that are subject to the standard in a given year. 
You may not generate credits for banking or trading in model years 2019 
or 2020, and you may not use banked or traded credits to demonstrate 
compliance with the standards in those years.
    (iii) The US06 emission standard for PM is 0.010 g/mile in model 
years 2019 through 2021, and 0.006 g/mile starting in model year 2022. 
The other standards described in this paragraph (b)(9) apply to all your 
vehicles above 6,000 pounds GVWR in model years 2022 through 2024.
    (10) You may not use credits generated from Tier 2 vehicles for 
demonstrating compliance with the Tier 3 standards except as specified 
in this paragraph (b)(10). You may generate early credits with U.S. 
sales of Tier 2 vehicles in the two model years before the Tier 3 
standards start to apply for a given vehicle model. Vehicles certified 
to the Tier 2 standards must meet all the Tier 2 requirements in Sec.
86.1811-10, including the fleet-average Tier 2 standards. Calculate 
early Tier 3 emission credits as described in Sec.86.1861 by 
subtracting the appropriate Tier 2 fleet-average value for FTP emissions 
of NMOG + NOX from 0.160 g/mile. Calculate your fleet-average 
value for the model year based on vehicles at or below 6,000 pounds GVWR 
in 2015, on all sizes of vehicles in 2016, and on vehicles above 6,000 
pounds GVWR in 2017. You may use these early credits as described in 
Sec.86.1861 for demonstrating compliance with the FTP emission 
standard for NMOG + NOX starting in model year 2017. You may 
use these early credits interchangeably for vehicles certified based on 
a useful life of either 120,000 or 150,000 miles. For model years 2018 
and later, you may use any remaining early credits for banking or 
trading subject to a limitation based on credits generated in 
California, as follows:
    (i) For the applicable model years in which you generate emission 
credits relative to California's LEV III fleet-

[[Page 972]]

average NMOG + NOX standard, determine the actual California 
sales of light-duty vehicles and light-duty trucks and the actual 
nationwide sales of those same vehicles. (Note: If you have a credit 
deficit in a given model year for your LEV III vehicles, apply the 
provisions of this paragraph (b)(10)(i) based on the appropriate 
negative credit quantity.) In 2015, count sales only from vehicle models 
at or below 6,000 pounds GVWR. For each model year, multiply the credits 
generated under the California program by the ratio of nationwide 
vehicle sales to LEV III vehicle sales to calculate an effective 
nationwide quantity. Sum these results for model years 2015 through 
2017. Note that this calculation results in a maximum credit quantity 
based on vehicle sales in all states, even though the initial credit 
calculation does not include vehicle sales in California or the section 
177 states. If you comply with the LEV III standards based on pooled 
emission credits for California and the section 177 states, use those 
pooled emission credits and corresponding sales for calculating the 
maximum credit quantity under this paragraph (b)(10)(i).
    (ii) You may not use more early credits generated under this 
paragraph (b)(10) for banking or trading to demonstrate compliance with 
Tier 3 emission standards than the calculated value of the effective 
nationwide credit quantity summed in paragraph (b)(10)(i) of this 
section. If your generated credits are greater than this threshold, 
determine the ratio by which your generated early credits exceed the 
threshold. Calculate an adjusted quantity of early credits generated 
under this paragraph (b)(10) by dividing the generated credit quantity 
from each model year by this ratio of generated credits relative to the 
applicable threshold. This adjusted quantity of credits may be used for 
banking or trading relative to the Tier 3 standards, subject to the 
five-year credit life described in Sec.86.1861.
    (11) You may certify vehicles to the Tier 3 standards starting in 
model year 2015. To do this, you may either sell all your LEV III 
vehicle models nationwide, or you may certify a subset of your fleet to 
alternate fleet-average emission standards as follows:
    (i) The alternate fleet-average FTP emission standards for NMOG + 
NOX are 0.100 g/mile in 2015 and 0.093 g/mile in 2016 for LDV 
and LDT1.
    (ii) The alternate fleet-average FTP emission standards for NMOG + 
NOX are 0.119 g/mile in 2015, 0.110 g/mile in 2016, and 0.101 
g/mile in 2017 for LDT2 and HLDT.
    (iii) The alternate fleet-average SFTP emission standards for NMOG + 
NOX are 0.140 in 2015 for all vehicles, 0.110 in 2016 for all 
vehicles, and 0.103 in 2017 for LDT2 and HLDT.
    (iv) The vehicles must meet FTP and SFTP standards for PM as 
specified in Sec.86.1811-04. The PM testing provisions of Sec.
86.1829-01(b)(1)(iii)(B) apply for these vehicles.
    (v) Vehicles not certified to the Tier 3 standards in a given model 
year must meet all the requirements that apply for Tier 2 vehicles in 
that model year.
    (vi) For cold temperature testing and for high-altitude testing, you 
may use the E0 fuel specified in Sec.86.113-04(a) or Sec.86.213 
instead of the E10 test fuel specified in Sec.86.113-15.
    (vii) Vehicles certified under this paragraph (b)(11) to a bin 
standard at or below Bin 70 must be certified to a useful life of 
150,000 miles.
    (viii) The interim provisions described in paragraph (b)(8)(iii) of 
this section apply for vehicles certified under this paragraph (b)(11), 
except that credits generated under this paragraph (b)(11) may be used 
interchangeably for vehicles certified based on a useful life of either 
120,000 or 150,000 miles.
    (ix) For vehicles certified under this paragraph (b)(11), you may 
generate emission credits and use those credits for demonstrating 
compliance with Tier 3 standards as described in paragraph (b)(10) of 
this section or as described in Sec.86.1861.
    (12) The following alternate standards apply for in-use testing:
    (i) Alternate in-use FTP standards for NMOG + NOX apply 
for 2021 and earlier model year vehicles certified to Bin 70 and lower. 
Calculate these alternate standards by multiplying the applicable FEL by 
1.4. These alternate

[[Page 973]]

standards apply only for testing at low-altitude conditions.
    (ii) The alternate in-use FTP standard for PM is 0.006 g/mile for 
2021 and earlier model year vehicles.
    (iii) The in-use US06 standard for PM is 0.010 g/mile for 2023 and 
earlier model year vehicles.
    (13) Keep records as needed to show that you meet the requirements 
specified in this paragraph (b) for phasing in standards and for 
complying with declining fleet-average average standards.
    (14) This subpart describes several ways that the transition to 
Final Tier 3 standards applies differently for vehicles above and below 
6,000 pounds GVWR. All these distinctions apply only for LDT. LDV as a 
category is defined independent of GVWR, so any LDV above 6,000 pounds 
GVWR are subject to the same provisions that apply for LDV at or below 
6,000 pounds GVWR. Where this section refers to ``vehicles above 6,000 
pounds GVWR,'' this should be understood to include LDT above 6,000 
pounds GVWR and MDPV (or HLDT and MDPV), and to exclude all LDV.
    (c) Highway NMOG + NOX exhaust emission standard. NMOG + 
NOX emissions measured on the federal Highway Fuel Economy 
Test in 40 CFR 1066.840 may not exceed the applicable FTP bin standard 
for NMOG + NOX. Demonstrate compliance with this standard for 
low-mileage vehicles by applying the appropriate deterioration factor. 
For vehicles not certified to any Tier 3 emission standards specified in 
paragraph (b) of this section, the provisions of Sec.86.1811-04(j) 
apply instead of this paragraph (c).
    (d) Special provisions for Otto-cycle engines. The special 
provisions described in this paragraph (d) apply for vehicles with Otto-
cycle engines. For vehicles not certified to any Tier 3 emission 
standards, the provisions of Sec.86.1810-01(i)(6), (i)(13), and 
(i)(14) apply instead of this paragraph (d).
    (1) Enrichment limits. The nominal air-fuel ratio throughout the 
US06 cycle may not be richer than the leanest air-fuel mixture required 
for lean best torque, except as allowed under paragraph (d)(2) of this 
section. Unless we approve otherwise in advance, lean best torque is the 
leanest air-fuel ratio required at any speed and load point with a fixed 
spark advance to make peak torque. The allowable tolerance around the 
nominal value for any given speed and load point over the US06 cycle for 
a particular vehicle is 4 percent, which is calculated as the nominal 
mass-based air-fuel ratio for lean best torque divided by 1.04.
    (2) Engine protection. AECDs that use commanded enrichment to 
protect the engine or emission control hardware must not use enrichment 
more frequently or to a greater degree than is needed for this purpose. 
For purposes of this section, commanded enrichment includes intended 
engine operation at air-fuel ratios rich of stoichiometry, except the 
following:
    (i) Cycling back and forth in a narrow window between rich and lean 
operation as a result of feedback controls targeted to maintain overall 
engine operation at stoichiometry.
    (ii) Small changes in the target air-fuel ratio to optimize vehicle 
emissions or drivability. This may be called ``closed-loop biasing.''
    (iii) Temporary enrichment in response to rapid throttle motion.
    (iv) Enrichment during cold-start and warm-up conditions.
    (v) Temporary enrichment for running OBD checks to comply with Sec.
86.1806.
    (3) A/C-on specific calibrations. (i) A/C-on specific calibrations 
(e.g., air-fuel ratio, spark timing, and exhaust gas recirculation) that 
differ from A/C-off calibrations may be used for a given set of engine 
operating conditions (e.g., engine speed, manifold pressure, coolant 
temperature, air charge temperature, and any other parameters). Such 
calibrations must not unnecessarily reduce emission control 
effectiveness during A/C-on operation when the vehicle is operated under 
conditions that may reasonably be expected during normal operation and 
use. If emission control effectiveness decreases as a result of such 
calibrations, the manufacturer must describe in the Application for 
Certification the circumstances under which this occurs and the reason 
for using these calibrations.

[[Page 974]]

    (ii) For AECDs involving commanded enrichment, these AECDs must not 
operate differently for A/C-on operation than for A/C-off operation, 
except as provided under paragraph (d)(2) of this section. This includes 
both the sensor inputs for triggering enrichment and the degree of 
enrichment employed.
    (4) ``Lean-on-cruise'' calibration strategies. Manufacturers may use 
``lean-on-cruise'' strategies subject to the following specifications:
    (i) A ``lean-on-cruise'' strategy is defined as the use of an air-
fuel ratio significantly leaner than stoichiometry during non-
deceleration conditions at speeds above 40 mph.
    (ii) You must not employ ``lean-on-cruise'' strategies during 
vehicle operation in normal driving conditions, including A/C usage, 
unless at least one of the following conditions is met:
    (A) Such strategies are substantially employed during the FTP, US06, 
or SC03 duty cycle.
    (B) Such strategies are demonstrated not to significantly reduce 
vehicle emission control effectiveness over the operating conditions in 
which they are employed.
    (C) Such strategies are demonstrated to be necessary to protect the 
vehicle occupants, engine, or emission control hardware.
    (iii) If you propose to use a ``lean-on-cruise'' strategy, you must 
describe in the application for certification the circumstances under 
which such a calibration would be used and the reasons for using it.
    (e) through (f) [Reserved]
    (g) Cold temperature exhaust emission standards. The standards in 
this paragraph (g) apply for certification and in-use vehicles tested 
over the test procedures specified in subpart C of this part. These 
standards apply only to gasoline-fueled vehicles. Multi-fuel, bi-fuel or 
dual-fuel vehicles must comply with requirements using gasoline only. 
Testing with other fuels such as a high-level ethanol-gasoline blend, or 
testing on diesel vehicles, is not required.
    (1) Cold temperature CO standards. Cold temperature CO exhaust 
emission standards apply for testing at both low-altitude conditions and 
high-altitude conditions as follows:
    (i) For LDV and LDT1, the standard is 10.0 g/mile CO.
    (ii) For LDT2, LDT3 and LDT4, the standard is 12.5 grams per mile 
CO.
    (2) Cold temperature NMHC standards. The following fleet average 
cold temperature NMHC standards apply as follows:
    (i) The standards are shown in the following table:

    Table 5 of Sec. 86.1811-17--Fleet Average Cold Temperature NMHC

    (ii) The manufacturer must calculate its fleet average cold 
temperature NMHC emission level(s) as described in Sec.86.1864-10(m).
    (iii) The standards specified in this paragraph (g)(2) apply only 
for testing at low-altitude conditions. However, manufacturers must 
submit an engineering evaluation indicating that common calibration 
approaches are utilized at high altitudes. Any deviation from low 
altitude emission control practices must be included in the auxiliary 
emission control device (AECD) descriptions submitted at certification. 
Any AECD specific to high altitude must require engineering emission 
data for EPA evaluation to quantify any emission impact and validity of 
the AECD.
    (h) Small-volume manufacturers. Small-volume manufacturers may use 
the following Tier 3 phase-in provisions:
    (1) Instead of the fleet-average FTP standards for NMOG + 
NOX specified in this section, small-volume manufacturers may 
meet alternate fleet-average standards of 0.125 g/mile through model 
year 2021, and 0.051 g/mile for model years 2022 through 2027. The 
following additional provisions apply for vehicles certified under this 
paragraph (h)(1):
    (i) Vehicles are subject to exhaust emission standards over the 
useful life as specified in Sec.86.1805-12 through

[[Page 975]]

model year 2021, and as specified in this section starting in model year 
2022.
    (ii) Gasoline-fueled vehicles may use the E0 test fuel specified in 
Sec.86.113-04 for vehicles certified to bins higher than Bin 70 
through model year 2021.
    (iii) Vehicles certified under this paragraph (h)(1) may generate 
emission credits and they may use banked or traded emission credits 
relative to the alternate fleet-average FTP standard for NMOG + 
NOX only in model years 2022 through 2027.
    (iv) Vehicles are subject to all the other requirements specified in 
this section.
    (2) Small-volume manufacturers may delay complying with all the 
requirements of this section until model year 2022, and instead meet all 
the requirements that apply to Tier 2 vehicles under Sec.86.1811-10 
for 2021 and earlier model years.
    (3) If meeting the Tier 3 standards would cause severe economic 
hardship, small-volume manufacturers may ask us to approve an extended 
compliance deadline under the provisions of 40 CFR 1068.250, except that 
the solvency criterion does not apply and there is no maximum duration 
of the hardship relief.

Sec.86.1813-17  Evaporative and refueling emission standards.

    Vehicles must meet evaporative and refueling emission standards as 
specified in this section. These standards apply for heavy duty vehicles 
above 14,000 pounds GVWR as specified in Sec.86.1801. The emission 
standards apply for total hydrocarbon equivalent (THCE) measurements 
using the test procedures specified in subpart B of this part, as 
appropriate. Note that Sec.86.1829 allows you to certify without 
testing in certain circumstances. Except as specified in paragraph (b) 
of this section, evaporative and refueling emission standards do not 
apply for diesel-fueled vehicles. Unless otherwise specified, MDPVs are 
subject to all the same provisions of this section that apply to LDT4.
    (a) Tier 3 evaporative emission standards. Vehicles may not exceed 
the Tier 3 evaporative emission standards, as follows:
    (1) Measure emissions using the test procedures of subpart B of this 
part, as follows:
    (i) Follow the vehicle preconditioning and exhaust testing 
procedures as described in subpart B of this part.
    (ii) Measure diurnal, running loss, and hot soak emissions as shown 
in Sec.86.130. This includes separate measurements for the two-diurnal 
test sequence and the three-diurnal test sequence; however, gaseous-
fueled vehicles are not subject to any evaporative emission standards 
using the two-diurnal test sequence.
    (iii) For gasoline-fueled vehicles, use E10 test fuel as required in 
Sec.86.113, except as specified in this section.
    (iv) Emissions are generally measured with a flame ionization 
detector (FID). In the case of rig, diurnal, hot soak, and running loss 
testing with E10 test fuel, multiply measured (unspeciated) FID values 
by 1.08 to account for the FID's reduced response to ethanol. However, 
you may instead determine total hydrocarbon equivalent for E10 testing 
based on speciated measurements as described in Sec.86.143-96(c). You 
may use different methods (with or without speciation) for different 
test elements for a given test vehicle; however, you must always use the 
same method for diurnal and hot soak testing. In addition, any later 
testing with vehicles from that evaporative/refueling family must use 
the same method that was used for the original testing. Similarly, any 
evaporative/refueling families certified in later model years using 
carryover data must use the same method that was used for the original 
testing. We may do testing with or without speciation, but we will apply 
the 1.08 correction factor to unspeciated measurements for any of these 
four categories of evaporative emissions only if you also use it to 
determine your final test results.
    (2) Diurnal and hot soak emissions may not exceed the Tier 3 
emission standards, as follows:

[[Page 976]]

    (i) The emission standard for the sum of diurnal and hot soak 
measurements from the two-diurnal test sequence and the three-diurnal 
test sequence is based on a fleet average in a given model year. You 
must specify a family emission limit (FEL) for each evaporative family. 
The FEL serves as the emission standard for the evaporative family with 
respect to all required diurnal and hot soak testing. Calculate your 
fleet-average emission level as described in Sec.86.1860 based on the 
FEL that applies for low-altitude testing to show that you meet the 
specified standard. For multi-fueled vehicles, calculate fleet-average 
emission levels based only on emission levels for testing with gasoline. 
You may generate emission credits for banking and trading and you may 
use banked or traded credits for demonstrating compliance with the 
diurnal plus hot soak emission standard for vehicles required to meet 
the Tier 3 standards, other than electric vehicles and gaseous-fueled 
vehicles, as described in Sec.86.1861 starting in model year 2017. You 
comply with the emission standard for a given model year if you have 
enough credits to show that your fleet-average emission level is at or 
below the applicable standard. You may exchange credits between or among 
evaporative families within an averaging set as described in Sec.
86.1861. Separate diurnal plus hot soak emission standards apply for 
each evaporative/refueling emission family as shown for high-altitude 
conditions. The sum of diurnal and hot soak measurements may not exceed 
the following Tier 3 standards:

   Table 1 of Sec. 86.1813-17--Tier 3 Diurnal Plus Hot Soak Emission
                                Standards

------------------------------------------------------------------------

    (ii) Specify FELs as follows:
    (A) You may specify the low-altitude FEL in increments of 0.025 g 
above or below the otherwise applicable Tier 3 diurnal plus hot soak 
standard, up to the maximum values specified in the following table:

 Table 2 of Sec. 86.1813-17--Tier 3 FEL Caps for Low-Altitude Testing
------------------------------------------------------------------------
                    Vehicle category                         FEL Caps

MDPV....................................................           1.000
HDV.....................................................             1.4
------------------------------------------------------------------------

    (B) Calculate the FEL for testing at high-altitude conditions based 
on the difference between the low-altitude FEL and the standard. For 
example, if a light-duty vehicle was certified with an FEL of 0.400 g 
instead of the 0.300 g standard, the FEL for testing under high-altitude 
conditions would be 0.75 g (0.65 + 0.10).
    (iii) Hydrocarbon emissions must not exceed 0.020 g for LDV and LDT 
and 0.030 g for HDV when tested using the Bleed Emission Test Procedure 
adopted by the California Air Resources Board as part of the LEV III 
program. This procedure quantifies diurnal emissions using the two-
diurnal test sequence without measuring hot soak emissions. The 
standards in this paragraph (a)(2)(iii) do not apply for testing at 
high-altitude conditions. For vehicles with non-integrated refueling 
canisters, the bleed emission test and standard do not apply to the 
refueling canister. You may perform the Bleed Emission Test Procedure 
using the analogous test temperatures and the E10 test fuel specified in 
subpart B of this part.
    (3) Running losses may not exceed 0.05 g per mile when measured 
using the test procedures specified in Sec.86.134. This standard does 
not apply for gaseous-fueled vehicles.
    (4) Fuel systems for vehicles operating on one or more volatile 
liquid fuels may not exceed an effective leak diameter of 0.02 inches 
when measured using the procedure specified in 40 CFR 1066.985. For 
vehicles with fuel tanks exceeding 25 gallons nominal fuel tank 
capacity, you may request our approval for a leak standard greater than 
0.020 inches, up to a maximum value of 0.040 inches.
    (5) The Tier 3 evaporative emission standards start to phase in with 
model

[[Page 977]]

year 2017 for vehicles at or below 6,000 pounds GVWR and with model year 
2018 for vehicles above 6,000 pounds GVWR. Table 3 of this section 
specifies the minimum percentage of each manufacturer's sales in each 
model year that must be certified to the Tier 3 evaporative emission 
standards. Calculate annual percentages based on actual nationwide sales 
of all vehicles subject to standards under this paragraph (a) for the 
applicable model year; however, if all your FELs for Tier 3 evaporative 
families are at the applicable standard (neither generating nor using 
emission credits), the phase-in requirements are based on projected 
sales. Also, if you certify vehicles above 6,000 pounds GVWR to the Tier 
3 evaporative emission standards in model year 2017, you may count 
projected U.S. sales of those vehicles toward your calculation for 
meeting the 40 percent requirement in 2017 (numerator only). 
Manufacturers may meet this requirement using the additional alternative 
phase-in provisions in paragraph (g) of this section. Vehicles from the 
identified model years not certified to the Tier 3 evaporative emission 
standards continue to be subject to the evaporative emission standards 
specified in Sec.86.1811-09(e) or Sec.86.1816-08(d), including the 
useful life provisions of Sec.86.1805-12. Note that this subjects LDV 
and LDT1 to a 150,000 mile useful life for evaporative emissions if the 
vehicles are subject to a 150,000 mile useful life for exhaust 
emissions. Keep records as needed to show that you meet the phase-in 
requirements specified in this section. See paragraph (g) of this 
section for additional provisions that apply for model year 2017 and the 
rest of the phase-in.

------------------------------------------------------------------------
\1\ The phase-in percentage for model year 2017 applies only for
  vehicles at or below 6,000 pounds GVWR.
\2\ The leak standard specified in paragraph (a)(4) of this section does
  not apply for model year 2017.

    (6) For model year 2017, exclude vehicle sales from California and 
section 177 states from the calculation to demonstrate compliance with 
the phase-in schedule in paragraph (a)(5) or (g) of this section, and 
from the credit calculation in Sec.86.1860.
    (b) Refueling emissions. Light-duty vehicles, light-duty trucks, and 
complete heavy-duty vehicles must meet the refueling emission standards 
in this paragraph (b) when measured over the procedure specified in 
Sec.86.150. These standards apply starting with model year 2018 for 
vehicles above 10,000 pounds GVWR. The following refueling standards 
apply:
    (1) 0.20 g THCE per gallon of fuel dispensed for vehicles using 
volatile liquid fuels. This standard also applies for diesel-fueled LDV.
    (2) 0.15 g THC per gallon of fuel dispensed for liquefied petroleum 
gas-fueled vehicles and natural gas-fueled vehicles.
    (c) Fuel spitback. For vehicles fueled by volatile liquid fuels, 
fuel spitback emissions may not exceed 1.0 g THCE when measured using 
the test procedures specified in Sec.86.146. The fuel spitback 
standard applies only to newly assembled vehicles.
    (d) [Reserved]
    (e) Auxiliary engines and separate fuel systems. The provisions of 
40 CFR 1037.103(g) apply for vehicles with auxiliary engines. This 
includes any engines installed in the final vehicle configuration that 
contribute no motive power through the vehicle's transmission.
    (f) Refueling provisions for gaseous-fueled vehicles. The following 
provisions apply specifically for gaseous-fueled vehicles:
    (1) Compressed natural gas vehicles must meet the requirements for 
fueling

[[Page 978]]

connection devices as specified in ANSI NGV1-2006 or CSA IR-1-15 
(incorporated by reference in Sec.86.1).
    (2) [Reserved]
    (3) With our advance approval, liquefied petroleum gas-fueled 
vehicles with gauges or valves that can be opened to release fuel or 
fuel vapor during refueling (such as fixed liquid level gauges) may be 
tested for refueling emissions without opening such gauges or valves, as 
outlined in Sec.86.157-98(d)(2). We will approve your request if you 
can show that such gauges or valves will not be open during in-use 
refueling due to inaccessibility or other design features that would 
prevent them from opening or make this very unlikely.
    (g) Alternative phase-in options for Tier 3 evaporative emission 
standards. You may use any of the following alternative methods to 
transition to the Tier 3 evaporative emission standards:
    (1) Starting in model year 2015, you may earn an ``allowance'' for 
each vehicle that you certify early under this paragraph (g)(1). For 
each allowance you earn, you may count it as one compliant vehicle in a 
later model year during the phase-in period. Calculate the total phase-
in percentage in each model year by adding the allowances to the number 
of compliant vehicles (in the numerator), without increasing total sales 
(in the denominator). For each allowance you earn, you may alternatively 
count it as one compliant vehicle under the phase-in schedule described 
in paragraph (g)(5) of this section, except that you may not use those 
allowances to increase the value of the phase-in index from any model 
year by more than 10 percentage points. Vehicles earning allowances 
under this paragraph (g)(1) may not have an FEL above the applicable 
Tier 3 standard, and may not generate emission credits for banking or 
trading. Allowances may not be traded to another company. You may earn 
allowances under this paragraph (g)(1) for early-compliant vehicles as 
follows:
    (i) Model year 2015 and 2016 vehicles at or below 6,000 pounds GVWR 
meeting the Tier 3 standards in paragraph (a) of this section or the 
equivalent California standards as specified in paragraph (g)(4) of this 
section earn allowances, as long as the vehicles are not sold in 
California or any of the section 177 states.
    (ii) Model year 2015 through 2017 LDV and LDT above 6,000 pounds 
GVWR meeting the Tier 3 standards in paragraph (a) of this section or 
the equivalent California standards as specified in paragraph (g)(4) of 
this section earn allowances, as long as the vehicles are not sold in 
California or any of the section 177 states.
    (iii) Model year 2015 through 2017 MDPV and HDV meeting the Tier 3 
standards in paragraph (a) of this section or the equivalent California 
standards as specified in paragraph (g)(4) of this section earn 
allowances for vehicles sold in any state.
    (iv) To the extent that you over-comply with the 40-percent phase-in 
requirement in model year 2017, you may count your actual U.S. sales 
exceeding the required number of Tier 3 vehicles as allowances toward 
meeting the phase-in requirement in 2018 and later model years.
    (v) For HDV above 10,000 pounds GVWR and at or below 14,000 pounds 
GVWR that you certify to the refueling emission standards in paragraph 
(b) of this section in model years 2015 through 2017 and sell outside of 
California and the section 177 states, a single vehicle may produce two 
allowances if it is certified to the Tier 3 diurnal plus hot soak 
standard. Allowances earned under this paragraph (g)(1)(v) may 
alternatively be used in model years 2018 through 2022 to phase in the 
refueling standard, except that a single early-compliant vehicle 
produces only a single allowance.
    (vi) Complete HDV above 14,000 pounds GVWR and all sizes of 
incomplete HDV earn allowances as described in paragraph (g)(1)(v) of 
this section if they are certified to the refueling emission standards 
in paragraph (b) of this section in model years 2015 through 2021.
    (2) The following alternative phase-in options apply for model year 
2017:
    (i) You may disregard the percentage phase-in specified in paragraph 
(a)(5) of this section for 2017 if you choose 50-state certification for 
all your vehicles meeting the LEV III PZEV evaporative standards in 
2017. Under this option, you may not produce a higher-emitting

[[Page 979]]

version of those vehicle models for sale outside of California or the 
section 177 states. Such vehicles may be certified using carryover data 
under the California program, but they may not generate or use emission 
credits. LDV and LDT1 that comply under this paragraph (g)(2)(i) may not 
generate allowances under paragraph (g)(1) of this section, regardless 
of the calculated percentage of compliant vehicles in model year 2017.
    (ii) You may comply with the phase-in requirement for model year 
2017 by meeting the Tier 3 emission standards for diurnal plus hot soak, 
running loss, and bleed emissions (or the equivalent set of California 
standards as allowed in this section) with 20 percent of vehicles at or 
below 6,000 pounds GVWR, and by meeting the leak standard in paragraph 
(a)(2)(iii) of this section with 20 percent of vehicles at or below 
6,000 pounds GVWR. You may optionally include vehicles above 6,000 
pounds GVWR under this paragraph (g)(2)(ii) to calculate the percentage 
(numerator only) if they meet the leak and/or evaporative emission 
standards in model year 2017. Vehicles complying with Tier 3 evaporative 
emission standards may generate or use emission credits relative to the 
diurnal plus hot soak standard as specified in this section, but they 
may not generate allowances. You may apply this option and use the 
alternative phase-in calculation in paragraph (g)(4) of this section, 
subject to the following conditions:
    (A) You must meet or exceed the 20 percent threshold for both 
evaporative emissions and the leak standard.
    (B) All the vehicles meeting the leak standard must also meet the 
Tier 3 evaporative emission standards and the OBD requirements in Sec.
86.1806-17(b)(1).
    (C) Determine the appropriate percentage for calculating compliance 
under paragraph (g)(4) of this section by adding 20 to the percentage of 
vehicles meeting the Tier 3 evaporative emission standards to account 
for vehicles meeting the leak standard. Do not increase the percentage 
based on meeting the leak standard with more than 20 percent of your 
vehicles in model year 2017.
    (3) If you certify model year 2021 or earlier vehicles to the LEV 
III evaporative emission standards in California, you may certify those 
as Tier 3 vehicles that count toward meeting the phase-in requirements 
of this section. Such vehicles must still be certified to the high-
altitude standards in paragraph (a)(2) of this section and the leak 
standard specified in paragraph (a)(4) of this section. You may not 
certify vehicles under this paragraph (g)(3) after model year 2021. 
Vehicles meeting the LEV III standards may also generate allowances 
under paragraph (g)(1) of this section; however, these vehicles may 
generate or use emission credits under this subpart only if they are not 
used to generate allowances and if they are certified using the Option 2 
procedures under the LEV III program (including the bleed emission 
test). Vehicles may be certified under this paragraph (g)(3) based on 
the rig test (``Option 1'') if they are certified to LEV III standards 
based on the rig test before model year 2017; this certification option 
applies through model year 2021. Include these Option 1 vehicles in the 
calculation of fleet average emissions by using the appropriate Tier 3 
emission standard as the FEL. Note that the rig test is considered a 
diurnal test with respect to the provisions to account for ethanol 
emissions as described in paragraph (a)(1)(iv) of this section.
    (4) If you fall short of the phase-in percentage specifications in 
paragraph (a)(5) of this section, you may designate the requisite number 
of Tier 2 vehicles as Tier 3 vehicles for purposes of demonstrating 
compliance with the Tier 3 standards in this section. To do this, factor 
those Tier 2 vehicles into the Tier 3 fleet-average emission calculation 
using an FEL that is equal to the applicable diurnal plus hot soak 
standard from the two-day test sequence. The Tier 3 emission standards 
do not apply to these Tier 2 vehicles. In addition, you may disregard 
the phase-in percentages specified in paragraph (a)(5) of this section 
if you instead comply based on one of the following alternative 
measures:
    (i) You may comply with an alternate phase-in schedule described in 
this paragraph (g)(4)(i). To do this, you

[[Page 980]]

must give us a detailed plan for describing how you will meet the 
alternate phase-in schedule. You comply with the alternate phase-in 
schedule by calculating an evaporative phase-in index using the 
following equation that is at or above 1,280 for model years 2017 
through 2022 (or 1,040 for model years 2018 through 2022 if you use the 
provisions of paragraph (g)(2)(i) of this section):

Evaporative phase-in index = 6[middot]APP2017 + 
5[middot]APP2018 + 4[middot]APP2019 + 
3[middot]APP2020 + 2[middot]APP2021 + 
APP2022

Where:

APP = The phase-in percentage of vehicles meeting the Tier 3 evaporative 
          emission standards for the indicated model year, based on 
          actual sales, as described in paragraph (a)(5) of this 
          section.

    (ii) You may comply with an alternate phase-in schedule described in 
this paragraph (g)(4)(ii). To do this, you must give us a detailed plan 
for describing how you will meet the alternate phase-in schedule. You 
comply with the alternate phase-in schedule by calculating an 
evaporative phase-in index using the following equation that is at or 
above 420 for model years 2017 through 2022 (or 380 for model years 2018 
through 2022 if you use the provisions of paragraph (g)(2)(i) of this 
section):

Evaporative phase-in index = APP2017 + APP2018 + 
APP2019 + APP2020 + APP2021 + 
APP2022

Where:

APP = The phase-in percentage of vehicles meeting the Tier 3 evaporative 
          emission standards for the indicated model year, based on 
          actual sales, as described in paragraph (a)(5) of this 
          section.

    (5) This paragraph (g)(5) describes an alternative approach to 
phasing in the evaporative and refueling emission standards for gaseous-
fueled vehicles above 8,500 pounds GVWR. Under this alternative phase-
in, you may disregard the requirements of this section related to 
evaporative emission standards that apply for these vehicles before 
model year 2019. Similarly, you may disregard the refueling emission 
standards of this section before model year 2019 for vehicles above 
10,000 pounds GVWR. For model year 2019, you may exclude from the phase-
in calculation any evaporative families with vehicles that have a Job 1 
date on or before March 3, 2018 (see 40 CFR 85.2304). Any vehicles not 
subject to Tier 3 evaporative emission standards during this phase-in 
period must continue to comply with the evaporative emission standards 
in Sec.86.1816-08(d); such vehicles are subject to the useful life 
provisions in Sec.86.1805-12 relative to evaporative emission 
standards. Each vehicle counting toward the phase-in percentage under 
this paragraph (g)(5) must meet all the standards that apply throughout 
the useful life as specified in Sec.86.1805-17.
    (h) Small-volume manufacturers. Small-volume manufacturers meeting 
the eligibility requirements in Sec.86.1838 may delay complying with 
the requirements in this section until model year 2022. If meeting the 
Tier 3 standards would cause severe economic hardship, such 
manufacturers may ask us to approve an extended compliance deadline 
under the provisions of 40 CFR 1068.250, except that the solvency 
criterion does not apply and there is no maximum duration of the 
hardship relief.

per mile.
    (4) Gasoline and methanol fuel only. Fuel dispensing spitback test: 
1.0 grams per test.
    (e) Refueling emissions--(1) Standards. Refueling emissions from 
Otto-cycle complete heavy-duty vehicles equal to or less than 10,000 
pounds Gross Vehicle Weight Rating shall be phased in, in accordance 
with the schedule in Table S01-5 in Sec.86.1810-01 not to exceed the 
following emission standards:
    (i) For gasoline-fueled and methanol-fueled vehicles: 0.20 grams 
hydrocarbon per gallon (0.053 gram per liter) of fuel dispensed.
    (ii) For liquefied petroleum gas-fueled vehicles: 0.15 grams 
hydrocarbon per gallon (0.04 gram per liter) of fuel dispensed.
    (2) Phase-in. Complete heavy-duty vehicles subject to refueling 
standards must comply with the phase-in requirements found in Table S01-
5 in Sec.86.1810-01, and must be grouped with HLDTs and MDPVs to 
determine phase-in compliance.
    (3) Alternate timing. (i) For manufacturers choosing Otto-cycle HDE

86.005-1(c)(3), the manufacturer may exempt 2005 model year HDE test 
groups whose model year begins before July 31, 2004. Only 2005 model 
year HDE test groups whose model year begins on or after July 31, 2004 
shall be considered (together with all 2005 model year HLDTs and MDPVs) 
for purposes of calculating the sales percentage for phase-in as 
outlined in Sec.86.1810-01(k).
    (iii) For complete heavy-duty vehicles which have total fuel tank 
capacity of greater than 35 gallons, or which do not share a common fuel 
system with a light-duty truck or medium-duty passenger vehicle 
configuration, the refueling emissions standards are optional for the 
2004 and 2005 model years.

[[Page 982]]

    (4) Exceptions. The provisions of this Sec.86.1816-05(e) do not 
apply to incomplete heavy-duty vehicles optionally certified to complete 
heavy duty vehicle standards under the provisions of Sec.86.1801-
01(c)(2).
    (f) [Reserved]
    (g) Idle exhaust emission standards, complete heavy-duty vehicles. 
Exhaust emissions of carbon monoxide from 2005 and later model year 
gasoline, methanol, natural gas-and liquefied petroleum gas-fueled 
complete heavy-duty vehicles shall not exceed 0.50 percent of exhaust 
gas flow at curb idle for a useful life of 11 years or 120,000 miles, 
whichever occurs first. This does not apply for vehicles certified to 
the requirements of Sec.86.1806-05
    (h) Alternate test groups. Manufacturers may request to group 
complete heavy-duty vehicles into the same test group as vehicles 
subject to more stringent standards, so long as those complete heavy-
duty vehicles meet the most stringent standards applicable to any 
vehicle within that test group, as provided at Sec.86.1827-(a)(5) and 
(d)(4).

Sec.86.1816-08  Emission standards for complete heavy-duty vehicles.

    Section 86.1816-08 includes text that specifies requirements that 
differ from those specified in Sec.86.1816-05. Where a paragraph in 
Sec.86.1816-05 is identical and applicable to Sec.86.1816-08, this 
may be indicated by specifying the corresponding paragraph and the 
statement ``[Reserved]. For guidance see Sec.86.1816-05.''. This 
section applies to 2008 and later model year complete heavy-duty 
vehicles (excluding MDPVs) fueled by gasoline, methanol, natural gas and 
liquefied petroleum gas fuels except as noted. Multi-fueled vehicles 
shall comply with all requirements established for each consumed fuel. 
For methanol fueled vehicles, references in this section to hydrocarbons 
or total hydrocarbons shall mean total hydrocarbon equivalents and 
references to non-methane hydrocarbons shall mean non-methane 
hydrocarbon equivalents.
    (a) Exhaust emission standards. (1) Exhaust emissions from 2008 and 
later model year complete heavy-duty vehicles at and above 8,500 pounds 
Gross Vehicle Weight Rating but equal to or less than 10,000 Gross 
Vehicle Weight Rating pounds shall not exceed the following standards at 
full useful life:
    (i) [Reserved]
    (ii) Non-methane hydrocarbons. (A) 0.195 grams per mile; this 
requirement may be satisfied by measurement of non-methane organic gas 
or total hydrocarbons, at the manufacturer's option. For alcohol-fueled 
vehicles, this standard is 0.195 grams per mile NMHCE.
    (B) A manufacturer may elect to include any or all of its test 
groups in the NMHC emissions ABT programs for heavy-duty vehicles, 
within the restrictions described in Sec.86.1817-05. or Sec.86.1817-
08. If the manufacturer elects to include test groups in any of these

vehicles, within the restrictions described in Sec.86.1817-05 or Sec.
86.1817-08. If the manufacturer elects to include test groups in any of 
these programs, the NOX FEL may not exceed 0.9 grams per 
mile. This ceiling value applies whether credits for the family are 
derived from averaging, banking, or trading.
    (v) Particulate. 0.02 grams per mile.
    (vi) Formaldehyde. 0.032 grams per mile.
    (2) Exhaust emissions from 2008 and later model year complete heavy-
duty vehicles above 10,000 pounds Gross Vehicle Weight Rating but less 
than 14,000 pounds Gross Vehicle Weight Rating shall not exceed the 
following standards at full useful life:
    (i) [Reserved]
    (ii) Non-methane hydrocarbons. (A) 0.230 grams per mile; this 
requirement may be satisfied by measurement of non-methane organic gas 
or total hydrocarbons, at the manufacturer's option. For alcohol-fueled 
vehicles, this

[[Page 983]]

standard is 0.230 grams per mile NMHCE.
    (B) A manufacturer may elect to include any or all of its test 
groups in the NMHC emissions ABT programs for heavy-duty vehicles, 
within the restrictions described in Sec.86.1817-05. or Sec.86.1817-
08. If the manufacturer elects to include test groups in any of these 
programs, the NMHC FEL may not exceed 0.33 grams per mile. This ceiling 
value applies whether credits for the family are derived from averaging, 
banking, or trading.
    (iii) Carbon monoxide. 8.1 grams per mile.
    (iv) Oxides of nitrogen. (A)0.4 grams per mile.
    (B) A manufacturer may elect to include any or all of its test

Sec.86.1817-08. If the manufacturer elects to include test groups in 
any of these programs, the NOX FEL may not exceed 1.0 grams 
per mile. This ceiling value applies whether credits for the family are 
derived from averaging, banking, or trading.
    (v) Particulate. 0.02 grams per mile.
    (vi) Formaldehyde. 0.040 grams per mile.
    (b)-(c) [Reserved]
    (d) Evaporative emissions. Evaporative hydrocarbon emissions from 
gasoline-fueled, natural gas-fueled, liquefied petroleum gas-fueled, and 
methanol-fueled complete heavy-duty vehicles shall not exceed the 
following standards. The standards apply equally to certification and 
in-use vehicles. The spitback standard also applies to newly assembled 
vehicles.
    (1) For the full three-diurnal test sequence, diurnal plus hot soak 
measurements: 1.4 grams per test.
    (2) Gasoline and methanol fuel only. For the supplemental two-
diurnal test sequence, diurnal plus hot soak measurements: 1.75 grams 
per test.
    (3) Gasoline and methanol fuel only. Running loss test: 0.05 grams 
per mile.
    (4) Gasoline and methanol fuel only. Fuel dispensing spitback test: 
1.0 grams per test.
    (e) through (h) [Reserved]. For guidance see Sec.86.1816-05.
    (i) Phase-in options. (1)(i) For model year 2008, manufacturers may 
certify some of their test groups to the standards applicable to model 
year 2008 vehicles under Sec.86.1816-05, in lieu of the exhaust 
standards specified in this section. These vehicles must comply with all 
other requirements applicable to model year 2007 vehicles. The combined 
number of vehicles in the test groups certified to the 2008 standards 
may not exceed 50 percent of the manufacturer's U.S. heavy-duty vehicle 
sales of complete heavy-duty Otto-cycle motor vehicles for model year 
2008, except as explicitly allowed by paragraph (i)(2) of this section.
    (ii) For model year 2008, manufacturers may certify some of their 
test groups to the evaporative standards applicable to model year 2007 
engines under Sec.86.1816-05, in lieu of the evaporative standards 
specified in this section. These vehicles must comply with all other 
requirements applicable to model year 2008 vehicles, except as allowed 
by paragraph (i)(1)(i) of this section. The combined number of vehicles 
in the test groups certified to the 2007 standards may not exceed 50 
percent of the manufacturer's U.S. heavy-duty vehicle sales of complete 
heavy-duty Otto-cycle motor vehicles for model year 2008.
    (2)(i) Manufacturers certifying vehicles to all of the applicable 
standards listed in paragraph (a) of this section prior to model year 
2008 (without using credits) may reduce the number of vehicles that are 
required to meet the standards listed in paragraph (a) of this section 
in model year 2008 and/or 2009, taking into account the phase-in option 
provided in paragraph (i)(1) of this section. For every vehicle that is 
certified early, the manufacturer may reduce the number of vehicles that 
are required by paragraph (i)(1) of this section to meet the standards 
listed in paragraph (a) of this section by one vehicle. For example, if 
a manufacturer produces 100 heavy-duty Otto-cycle vehicles in 2007 that 
meet all of the applicable the standards listed in paragraph (a) of this 
section, and it produced 10,000 heavy-duty Otto-cycle vehicles in 2009, 
then only 9,900 of the vehicles

[[Page 984]]

would need to comply with the standards listed in paragraph (a) of this 
section.
    (ii) Manufacturers certifying vehicles to all of the applicable 
evaporative standards listed in paragraph (d) of this section prior to 
model year 2008 may reduce the number of vehicles that are required to 
meet the standards listed in paragraph (d) of this section in model year 
2008 and/or 2009, taking into account the phase-in option provided in 
paragraph (i)(1) of this section. For every vehicle that is certified 
early, the manufacturer may reduce the number of vehicles that are 
required by paragraph (i)(1) of this section to meet the evaporative 
standards listed in paragraph (d) of this section by one vehicle.
    (3) Manufacturers certifying vehicles to all of the applicable 
standards listed in paragraph (i)(3)(i) or (ii) of this section (without 
using credits) and the evaporative standards listed in paragraph (d) of 
this section prior to model year 2008 may reduce the number of vehicles 
that are required to meet the standards listed in paragraph (a) of this 
section in model year 2008 and/or 2009, taking into account the phase-in 
option provided in paragraph (i)(1)(i) of this section. For every such 
vehicle that is certified early with sufficiently low emissions, the 
manufacturer may reduce the number of vehicles that are required by 
paragraph (i)(1)(i) of this section to meet the standards listed in 
paragraph (a) of this section by two vehicles. The applicable standards 
are:
    (i) For complete heavy-duty vehicles at and above 8,500 pounds Gross 
Vehicle Weight Rating but equal to or less than 10,000 Gross Vehicle 
Weight Rating: 0.100 g/mile NMHC, 0.10 g/mile NOX, 3.2 g/mile 
CO, 0.008 g/mile formaldehyde, and 0.02 g/mile PM.
    (ii) For complete heavy-duty vehicles at or above 10,000 pounds 
Gross Vehicle Weight Rating but equal to or less than 14,000 Gross 
Vehicle Weight Rating: 0.117 g/mile NMHC, 0.20 g/mile NOX, 
3.7 g/mile CO, 0.010 g/mile formaldehyde, and 0.02 g/mile PM.
    (j) (1) For model years prior to 2012, for purposes of determining 
compliance after title or custody has transferred to the ultimate 
purchaser, for vehicles meeting the applicable emission standards of 
this section, the applicable compliance limits shall be determined by 
adding the applicable adjustment from paragraph (j)(2) of this section 
to the otherwise applicable standard or FEL.
    (2) The in-use adjustments are:
    (i) 0.1 g/mi for NOX.
    (ii) 0.100 g/mi NMHC.
    (iii) 0.01 g/mi for PM.

Sec.86.1816-18  Emission standards for heavy-duty vehicles.

    (a) Applicability and general provisions. This section describes 
exhaust emission standards that apply for model year 2018 and later 
complete heavy-duty vehicles. These standards are optional for 
incomplete heavy-duty vehicles and for heavy duty vehicles above 14,000 
pounds GVWR as described in Sec.86.1801. Greenhouse gas emission 
standards are specified in Sec.86.1818 for MDPV and in Sec.86.1819 
for other HDV. See Sec.86.1813 for evaporative and refueling emission 
standards. This section may apply to vehicles before model year 2018 as 
specified in paragraph (b)(11) of this section. Separate requirements 
apply for MDPV as specified in Sec.86.1811. See subpart A of this part 
for requirements that apply for incomplete heavy-duty vehicles and for 
heavy-duty engines certified independent of the chassis. The following 
general provisions apply:
    (1) Test all vehicles as described in this section using a chassis 
dynamometer; establish appropriate load settings based on adjusted 
loaded vehicle weight (see Sec.86.1803).
    (2) Some provisions apply differently depending on the vehicle's 
power-to-weight ratio. Determine a vehicle's power-to-weight ratio by 
dividing the engine's rated power by the vehicle's GVWR (in hp/pound). 
For purposes of this section, if a test group includes multiple 
configurations, use the vehicle with the highest power-to-weight ratio 
to characterize the test group.
    (3) Use E10 test fuel as required in Sec.86.113, except as 
specified in this section.
    (4) Measure emissions from hybrid electric vehicles (including plug-
in hybrid electric vehicles) as described in 40

[[Page 985]]

CFR part 1066, subpart F, except that these procedures do not apply for 
plug-in hybrid electric vehicles during charge-depleting operation.
    (b) Tier 3 exhaust emission standards. Exhaust emissions may not 
exceed the Tier 3 exhaust emission standards, as follows:
    (1) Measure emissions using the procedures of subpart B of this 
part, using specific driving schedules and additional procedures as 
follows:
    (i) The Federal Test Procedure (FTP) is based on testing with the 
Urban Dynamometer Driving Schedule (UDDS) specified in paragraph (a) of 
Appendix I of this part.
    (ii) The Heavy-Duty Supplemental Federal Test Procedure (HD-SFTP) 
involves testing with the UDDS, the SC03 driving schedule specified in 
paragraph (h) of Appendix I of this part, and one of the following 
additional driving schedules:
    (A) For Class 2b vehicles, the US06 driving schedule specified in 
paragraph (g) of Appendix I of this part.
    (B) For Class 2b vehicles with a power-to-weight ratio at or below 
0.024 hp/pound that are certified to optional standards under paragraphs 
(b)(2) and (4) of this section, the highway portion of the US06 driving 
schedule characterized as the ``second bag'' in Sec.86.159-08(a).
    (C) For Class 3 vehicles, the Hot LA-92 driving schedule as 
specified in paragraph (c) of Appendix I of this part.
    (iii) HD-SFTP emissions are calculated as a composite of test 
results over these driving schedules based on the following calculation:

HD-SFTP (g/mi) = 0.35[middot]FTP + 0.28[middot]HDSIM + 0.37[middot]SC03

Where:

HDSIM = the appropriate driving schedule specified in paragraph 
          (b)(1)(ii)(A) through (C) of this section.

    (iv) You may alternatively use FTP emission results to substitute 
for the SC03 value in the calculation under paragraph (b)(1)(iii) of 
this section for a given vehicle for any testing under this section. 
Such vehicles remain subject to the SFTP standard when tested over the 
SC03 driving schedule.
    (v) Hydrocarbon emission standards are expressed as NMOG; however, 
you may measure exhaust emissions based on nonmethane hydrocarbon 
instead of NMOG as described in 40 CFR 1066.635.
    (2) Table 1 of this section describes fully phased-in Tier 3 
standards that apply as specified in this paragraph (b) for the 
identified driving schedules. The FTP standards for NMOG + 
NOX apply on a fleet-average basis using discrete bin 
standards as described in paragraph (b)(4) of this section. The bin 
standards include additional emission standards for CO emissions, and 
for NMOG + NOX standards when testing over the HD-SFTP 
driving schedule. Table 1 follows:

----------------------------------------------------------------------------------------------------------------
\1\ For vehicles with a power-to-weight ratio at or below 0.024 hp/pound that are certified using the driving
  schedule described in paragraph (b)(1)(ii)(B) of this section, the HD-SFTP standard for PM is 0.007 g/mile
  instead of the value specified in the table.

    (3) The FTP standards specified in this section apply equally for 
testing at low-altitude conditions and high-altitude conditions. The HD-
SFTP standards described in this section apply only for testing at low-
altitude conditions.
    (4) The FTP emission standard for NMOG + NOX is based on 
a fleet average in a given model year. You must specify a family 
emission limit (FEL) for each test group. The FEL serves as the emission 
standard for the test group with respect to all required FTP testing. 
Calculate your fleet-average emission level as described in Sec.
86.1860 to show that you meet the specified standard. For multi-fueled 
vehicles,

[[Page 986]]

calculate fleet-average emission levels based only on emission levels 
for testing with gasoline or diesel fuel. You may generate or use 
emission credits for banking and trading and you may use banked or 
traded credits for demonstrating compliance with the FTP emission 
standard for NMOG + NOX as described in Sec.86.1861. You 
comply with the emission standard for a given model year if you have 
enough credits to show that your fleet-average emission level is at or 
below the applicable standard. You may exchange credits between or among 
any test groups subject to standards under this section. Specify one of 
the identified values from Table 2 or Table 3 of this section as the FEL 
for demonstrating that your fleet-average emission level complies with 
the FTP emission standard for NMOG + NOX. These FEL values 
define emission bins that also determine corresponding emission 
standards for NMOG + NOX emissions over the HD-SFTP driving 
schedule and for CO emissions, as follows:

\1\ Vehicles certified to Bin 0 must also meet PM and formaldehyde standards of 0.000 g/mile instead of the
  standards specified in paragraph (b)(2) of this section.

    (5) [Reserved]
    (6) The full Tier 3 program includes new emission standards for NMOG 
+ NOX, PM, CO, and formaldehyde; it also includes measurement 
with a new test fuel and a longer useful life. Vehicles meeting all 
these requirements are considered Final Tier 3 vehicles. Vehicles that 
do not meet all the Tier 3 requirements are considered Interim Tier 3 
vehicles. The Tier 3 PM standards phase in over several years. Any 
vehicles not subject to Tier 3 PM standards during the phase-in period 
must continue to comply with the PM standards in Sec.86.1816-08. 
Paragraph (b)(7) of this section describes how to transition to Tier 3 
standards for emissions other than PM. The following provisions describe 
the primary approach for phasing in the Tier 3 PM standards:
    (i) You must meet the FTP emission standard for PM with 20, 40, 70, 
and 100 percent of your projected nationwide sales of all vehicles 
subject to this section in model years 2018 through 2021, respectively. 
Each vehicle meeting the Tier 3 FTP standard for PM must also meet the 
Tier 3 HD-SFTP standard for PM.
    (ii) You may disregard the phase-in percentages specified in 
paragraph (b)(6)(i) of this section if you instead comply with an 
indexed PM phase-in

[[Page 987]]

schedule as described in this paragraph (b)(6)(ii). To do this, you must 
notify us of your intent before January 1, 2018, and include a detailed 
plan for complying with the indexed phase-in schedule. You comply with 
the indexed phase-in schedule by calculating a PM phase-in index at or 
above 440 using the following equation for model years 2018 through 
2021:

PM phase-in index = 4[middot]APP2018 + 
3[middot]APP2019 + 2[middot]APP2020 + 
APP2021

Where:

APP = The phase-in percentage of vehicles meeting the Tier 3 PM 
          standards for the indicated model year, based on actual sales.

    (iii) Vehicles meeting the Tier 3 PM standards must meet those 
standards over the useful life as specified in Sec.86.1805. Note that 
Interim Tier 3 vehicles may have different useful life values for PM 
emission standards than for other emission standards.
    (iv) Measure PM emissions from all vehicles using the same test fuel 
used for measuring NMOG + NOX emissions.
    (v) You may certify Interim Tier 3 vehicles based on carryover data.
    (vi) You may use the alternative phase-in provisions described in 
paragraph (b)(8) of this section to transition to the Tier 3 exhaust 
emission standards on a different schedule.
    (7) The following provisions describe the primary approach for 
phasing in the Tier 3 standards other than PM in 2022 and earlier model 
years:
    (i) The fleet-average FTP emission standard for NMOG + 
NOX phases in over several years as described in this 
paragraph (b)(7)(i). You must identify FELs as described in paragraph 
(b)(4) of this section and calculate a fleet-average emission level to 
show that you meet the FTP emission standard for NMOG+NOX 
that applies for each model year. You may certify using transitional bin 
standards specified in Table 5 of this section through model year 2021; 
these vehicles are subject to the FTP emission standard for formaldehyde 
as described in Sec.86.1816-08. You may use the E0 test fuel specified 
in Sec.86.113 for gasoline-fueled vehicles certified to the 
transitional bins; the useful life period for these vehicles is 120,000 
miles or 11 years. Fleet-average FTP emission standards decrease as 
shown in the following table:

    (ii) You may use the alternative phase-in provisions described in 
paragraph (b)(8) of this section to transition to the Tier 3 exhaust 
emission standards on a different schedule.
    (8) This paragraph (b)(8) describes an alternative approach to 
phasing in the Tier 3 emission standards. If you choose this approach, 
you must phase in the Tier 3 standards for all your vehicles subject to 
this section according to this schedule. Under this alternative phase 
in, you must meet all the standards specified in paragraph (b)(2) of 
this section according to the phase-in schedule specified in Table 6 of 
this

section based on the indicated percentage of your projected nationwide 
sales in each model year. These vehicles must meet the applicable FTP 
emission standard for CO and the HD-SFTP emission standards for NMOG + 
NOX and CO that apply for Class 2b Bin 170 and Class 3 Bin 
230 as described in paragraph (b)(4) of this section. Any vehicles not 
subject to Tier 3 standards during the phase-in period must continue to 
comply with the gaseous exhaust emission standards in Sec.86.1816-08. 
Each vehicle counting toward the PM phase-in percentage under this 
paragraph (b)(8) in model years 2019 and 2020 must also be included in 
the portion of the fleet meeting the Tier 3 standards for pollutants 
other than PM. Each vehicle counting toward the phase-in percentage for 
any pollutant must use the Tier 3 test fuel specified in Sec.86.113-
15. The following exceptions and special provisions apply under this 
paragraph (b)(8):
    (i) For model year 2019, you may exclude from the phase-in 
calculation any test groups that have a Job 1 date on or before March 3, 
2018 (see 40 CFR 85.2304).
    (ii) You may generate Tier 3 emission credits during the phase-in 
period if all your pre-Tier 3 vehicles in a given model year have FELs 
at or below the NOX and NMHC standards in Sec.86.1816-08. 
Determine emission credits by calculating fleet-average emission levels 
for Tier 3 and pre-Tier 3 vehicles together; for pre-Tier 3 vehicles use 
an NMOG + NOX equivalent FEL of 0.395 g/mile for Class 2b 
vehicles and 0.630 g/mile for Class 3 vehicles.

These alternate standards apply in the first model year that a test 
group is certified to Tier 3 FTP or HD-SFTP standards for NMOG + 
NOX or PM under this section. The alternate in-use standards 
also apply in the following model year (but not beyond 2022) for 
carryover test groups certified to the same bin standards. If you 
certify a test group to more stringent bin standards under this section 
in a given model year, the alternate in-use standards apply as if that 
were the first model year of certifying to the Tier 3 standards. The 
provisions of this section apply separately for NMOG + NOX 
and PM. This paragraph (b)(12) does not apply for Bin 0 vehicles.
    (i) The alternate in-use FTP standards for PM are 0.016 g/mile for 
Class 2b vehicles and 0.020 g/mile for Class 3 vehicles.
    (ii) The alternate in-use HD-SFTP standards for PM are 0.012 g/mile 
for Class 2b vehicles with a power-to-weight ratio at or below 0.024 hp/
pound that are certified to optional standards under paragraphs (b)(2) 
and (4) of this

[[Page 989]]

section, and 0.015 g/mile for other Class 2b vehicles. The alternate in-
use HD-SFTP standard for PM is 0.012 g/mile for Class 3 vehicles. 
Alternate in-use HD-SFTP standards do not apply for vehicles certified 
to the transitional bins described in paragraph (b)(7) of this section.
    (iii) Alternate in-use FTP and HD-SFTP standards for NMOG + 
NOX apply as specified in the following table:

    (13) Keep records as needed to show that you meet the requirements 
specified in this paragraph (b) for phasing in standards and for 
complying with declining fleet-average average standards.
    (c) Highway NMOG + NOX exhaust emission standard. For vehicles 
certified to any of the Tier 3 standards specified in paragraph (b) of 
this section, NMOG + NOX emissions measured on the highway 
test cycle in 40 CFR 1066.840 may not exceed the applicable NMOG + 
NOX bin standard for FTP testing. Demonstrate compliance with 
this standard for low-mileage vehicles by applying the appropriate 
deterioration factor.
    (d) Provisions for Otto-cycle engines. The special provisions 
described in Sec.86.1811-17(d) apply to vehicles with Otto-cycle 
engines that are certified under this section.
    (e) Small-volume manufacturers. Small-volume manufacturers meeting 
the eligibility requirements in Sec.86.1838 may delay complying with 
the requirements in this section until model year 2022. This also 
applies for continuing to use the E0 test fuel specified in Sec.86.113 
through model year 2021. If meeting the Tier 3 standards would cause 
severe economic hardship, such manufacturers may ask us to approve an 
extended compliance deadline under the provisions of 40 CFR 1068.250, 
except that the solvency criterion does not apply and there is no 
maximum duration of the hardship relief.

FR 73984, Oct. 25, 2016]



Sec.86.1817-05  Complete heavy-duty vehicle averaging, trading, 
and banking program.

    (a) General. (1) Complete heavy-duty vehicles eligible for the 
NOX averaging, trading and banking program are described in 
the applicable emission standards section of this subpart. All heavy-
duty vehicles which include an engine labeled for use in clean-fuel 
vehicles as specified in 40 CFR part 88 are not eligible for this 
program. Participation in this averaging, trading, and banking program 
is voluntary.
    (2)(i) Test groups with a family emission limit (FEL) as defined in 
Sec.86.1803-01 exceeding the applicable standard shall obtain emission 
credits as defined in Sec.86.1803-01 in a mass amount sufficient to 
address the shortfall. Credits may be obtained from averaging, trading, 
or banking, as defined in Sec.86.1803-01 within the averaging set 
restrictions described in paragraph (d) of this section.
    (ii) Test groups with an FEL below the applicable standard will have 
emission credits available to average, trade, bank or a combination 
thereof. Credits may not be used for averaging or trading to offset 
emissions that exceed an FEL. Credits may not be used to remedy an in-
use nonconformity determined by a Selective Enforcement Audit or by 
recall testing. However, credits may be used to allow subsequent 
production of vehicles for the test group in question if the 
manufacturer elects to recertify to a higher FEL.

[[Page 990]]

    (b) Participation. Participation in the NOX averaging, 
trading, and banking program shall be done as follows:
    (1) During certification, the manufacturer shall:
    (i) Declare its intent to include specific test groups in the 
averaging, trading and banking program.
    (ii) Declare an FEL for each test group participating in the 
program.
    (A) The FEL must be to the same level of significant digits as the 
emission standard (one-hundredth of a gram per mile for NOX 
emissions).
    (B) In no case may the FEL exceed the upper limit prescribed in the 
section concerning the applicable complete heavy-duty vehicle chassis-
based NOX emission standard.
    (iii) Calculate the projected NOX emission credits 
(positive or negative) as defined in Sec.86.1803-01 based on quarterly 
production projections for each participating test group, using the 
applicable equation in paragraph (c) of this section and the applicable 
factors for the specific test group.
    (iv)(A) Determine and state the source of the needed credits 
according to quarterly projected production for test groups requiring 
credits for certification.
    (B) State where the quarterly projected credits will be applied for 
test groups generating credits.
    (C) Emission credits as defined in Sec.86.1803-01 may be obtained 
from or applied to only test groups within the same averaging set as 
defined in Sec.86.1803-01. Emission credits available for averaging, 
trading, or banking, may be applied exclusively to a given test group, 
or designated as reserved credits as defined in Sec.86.1803-01.
    (2) Based on this information, each manufacturer's certification 
application must demonstrate:
    (i) That at the end of model year production, each test group has a 
net emissions credit balance of zero or more using the methodology in 
paragraph (c) of this section with any credits obtained from averaging, 
trading or banking.
    (ii) The source of the credits to be used to comply with the 
emission standard if the FEL exceeds the standard, or where credits will 
be applied if the FEL is less than the emission standard. In cases where 
credits are being obtained, each test group involved must state 
specifically the source (manufacturer/test group) of the credits being 
used. In cases where credits are being generated/supplied, each test 
group involved must state specifically the designated use (manufacturer/
test group or reserved) of the credits involved. All such reports shall 
include all credits involved in averaging, trading or banking.
    (3) During the model year, manufacturers must:
    (i) Monitor projected versus actual production to be certain that 
compliance with the emission standards is achieved at the end of the 
model year.
    (ii) Provide the end-of-year reports required under paragraph (i) of 
this section.
    (iii) For manufacturers participating in emission credit trading, 
maintain the quarterly records required under paragraph (l) of this 
section.
    (4) Projected credits based on information supplied in the 
certification application may be used to obtain a certificate of 
conformity. However, any such credits may be revoked based on review of 
end-of-model year reports, follow-up audits, and any other compliance 
measures deemed appropriate by the Administrator.
    (5) Compliance under averaging, banking, and trading will be 
determined at the end of the model year. Test groups without an adequate 
amount of NOX emission credits will violate the conditions of 
the certificate of conformity. The certificates of conformity may be 
voided ab initio for test groups exceeding the emission standard.
    (6) If EPA or the manufacturer determines that a reporting error 
occurred on an end-of-year report previously submitted to EPA under this 
section, the manufacturer's credits and credit calculations will be 
recalculated. Erroneous positive credits will be void. Erroneous 
negative balances may be adjusted by EPA for retroactive use.
    (i) If EPA review of a manufacturer's end-of-year report indicates a 
credit shortfall, the manufacturer will be permitted to purchase the 
necessary credits to bring the credit balance for that test group to 
zero, at the ratio of 1.2

[[Page 991]]

credits purchased for every credit needed to bring the balance to zero. 
If sufficient credits are not available to bring the credit balance for 
the test group in question to zero, EPA may void the certificate for 
that test group ab initio.
    (ii) If within 180 days of receipt of the manufacturer's end-of-year 
report, EPA review determines a reporting error in the manufacturer's 
favor (i.e. resulting in a positive credit balance) or if the 
manufacturer discovers such an error within 180 days of EPA receipt of 
the end-of-year report, the credits will be restored for use by the 
manufacturer.
    (c) Calculations. For each participating test group, NOX 
emission credits (positive or negative) are to be calculated according 
to one of the following equations and rounded to the nearest one-tenth 
of a Megagram (Mg). Consistent units are to be used throughout the 
equation.
    (1) For determining credit need for all test groups and credit 
availability for test groups generating credits for averaging only:

Emission credits = (Std-FEL) x (UL) x (Production) x (10-6)

    (2) For determining credit availability for test groups generating 
credits for trading or banking:

Emission credits = (Std-FEL) x (UL) x (Production) x (10-6) 
(Discount)

    (3) For purposes of the equations in paragraphs (c)(1) and (c)(2) of 
this section:

Std = the current and applicable complete heavy-duty vehicle 
          NOX emission standard in grams per mile or grams 
          per kilometer.
Std = 0.9 grams per mile for heavy-duty vehicles at and above 8,500 
          pounds Gross Vehicle Weight Rating but equal to or less than 
          10,000 Gross Vehicle Weight Rating pounds and 1.0 grams per 
          mile for heavy-duty vehicles above 10,000 pounds Gross Vehicle 
          Weight Rating but less than 14,000 pounds Gross Vehicle Weight 
          Rating for cases where certification to chassis-based 
          standards is optional for purposes of early credit banking.
FEL = the NOX family emission limit for the test group in 
          grams per mile or grams per kilometer.
UL = the useful life, or alternative life as described in paragraph (c) 
          of Sec.86.1805-01, for the given test group in miles or 
          kilometers.
Production = the number of vehicles produced for U.S. sales within the 
          given test group during the model year. Quarterly production 
          projections are used for initial certification. Actual 
          production is used for end-of-year compliance determination.
Discount = a one-time discount applied to all credits to be banked or 
          traded within the model year generated. Except as otherwise 
          allowed in paragraph (m) of this section, the discount applied 
          here is 0.9. Banked credits traded in a subsequent model year 
          will not be subject to an additional discount. Banked credits 
          used in a subsequent model year's averaging program will not 
          have the discount restored.

    (d) Averaging sets. The averaging and trading of NOX 
emission credits will be allowed between all test groups of heavy-duty 
vehicles subject to chassis-based standards excluding those vehicles 
produced for sale in California. Averaging, banking, and trading are not 
applicable to vehicles sold in California.
    (e) Banking of NOX emission credits--(1) Credit deposits. 
(i) NOX emission credits may be banked from test groups 
produced in 2000 and later model years. Early banking is described in 
paragraph (n) of this section.
    (ii) Manufacturers may bank credits only after the end of the model 
year and after actual credits have been reported to EPA in the end-of-
year report. During the model year and before submittal of the end-of-
year report, credits originally designated in the certification process 
for banking will be considered reserved and may be redesignated for 
trading or averaging.
    (2) Credit withdrawals. (i) NOX credits do not expire, 
except as provided in paragraph (o)(2) of this section.
    (ii) Manufacturers withdrawing banked emission credits shall 
indicate so during certification and in their credit reports, as 
described in paragraph (i) of this section.
    (3) Use of banked emission credits. The use of banked credits shall 
be within the averaging set and geographic restrictions described in 
paragraph (d) of this section, and only for the following purposes:

[[Page 992]]

    (i) Banked credits may be used in averaging, or in trading, or in 
any combination thereof, during the certification period. Credits 
declared for banking from the previous model year but not reported to 
EPA may also be used. However, if EPA finds that the reported credits 
cannot be proven, they will be revoked and unavailable for use.
    (ii) Banked credits may not be used for averaging and trading to 
offset emissions that exceed an FEL. Banked credits may not be used to 
remedy an in-use nonconformity determined by a Selective Enforcement 
Audit or by recall testing. However, banked credits may be used for 
subsequent production of the test group if the manufacturer elects to 
recertify to a higher FEL.
    (f) Negative credit balance. In the event of a negative credit 
balance in a trading situation, both the buyer and the seller would be 
liable.
    (g) Fuel. Certification fuel used for credit generation must be of a 
type that is both available in use and expected to be used by the 
vehicle purchaser. Therefore, upon request by the Administrator, the 
vehicle manufacturer must provide information acceptable to the 
Administrator that the designated fuel is readily available commercially 
and would be used in customer service.
    (h) Credit apportionment. At the manufacturers option, credits 
generated from complete heavy-duty vehicles under the provisions 
described in this section may be sold to or otherwise provided to 
another party for use in programs other than the averaging, trading and 
banking program described in this section.
    (1) The manufacturer shall pre-identify two emission levels per test 
group for the purposes of credit apportionment. One emission level shall 
be the FEL and the other shall be the level of the standard that the 
test group is required to certify under Sec.86.1816-04. For each test 
group, the manufacturer may report vehicle sales in two categories, 
``ABT-only credits'' and ``nonmanufacturer-owned credits''.
    (i) For vehicle sales reported as ``ABT-only credits'', the credits 
generated must be used solely in the averaging, trading and banking 
program described in this section.
    (ii) The vehicle manufacturer may declare a portion of vehicle sales 
``nonmanufacturer-owned credits'' and this portion of the credits 
generated between the standard and the FEL, based on the calculation in 
paragraph (c)(1) of this section, would belong to the vehicle purchaser. 
The manufacturer may not generate any credits for the vehicle sales 
reported as ``nonmanufacturer-owned credits'' for this averaging, 
trading and banking program. Vehicles reported as ``nonmanufacturer-
owned credits'' shall comply with the FEL and the requirements of this 
averaging, trading and banking program in all other respects.
    (2) Only manufacturer-owned credits reported as ``ABT-only credits'' 
shall be used in the averaging, trading, and banking provisions 
described in this section.
    (3) Credits shall not be double-counted. Credits used in this 
averaging, trading and banking program may not be provided to a vehicle 
purchaser for use in another program.
    (4) Manufacturers shall determine and state the number of vehicles 
sold as ``ABT-only credits'' and ``nonmanufacturer-owned credits'' in 
the end-of-model year reports required under paragraph (i) of this 
section.
    (i) Application for certification and end-of-year reports. 
Manufacturers participating in the emissions averaging, trading and 
banking program, shall submit for each participating test group the 
items listed in paragraphs (i)(1) through (3) of this section.
    (1) Application for certification. (i) The application for 
certification will include a statement that the vehicles for which 
certification is requested will not, to the best of the manufacturer's 
belief, when included in the averaging, trading and banking program, 
cause the applicable NOX emissions standard to be exceeded.
    (ii) The application for certification will also include 
identification of the section of this subpart under which the test group 
is participating in the averaging, trading and banking program (e.g., 
Sec.86.1817-05), the type (NOX), and the projected number 
of credits generated/needed for this test group, the

[[Page 993]]

applicable averaging set, the projected U.S. production volumes 
(excluding vehicles produced for sale in California), by quarter, and 
the values required to calculate credits as given in the applicable 
averaging, trading and banking section. Manufacturers shall also submit 
how and where credit surpluses are to be dispersed and how and through 
what means credit deficits are to be met, as explained in the applicable 
averaging, trading and banking section. The application must project 
that each test group will be in compliance with the applicable emission 
standards based on the vehicle mass emissions and credits from 
averaging, trading and banking.
    (2) [Reserved]
    (3) End-of-year report. The manufacturer shall submit end-of-year 
reports for each test group participating in the averaging, trading and 
banking program, as described in paragraphs (i)(3)(i) through (iv) of 
this section.
    (i) These reports shall be submitted within 90 days of the end of 
the model year to: Director, Certification and Compliance Division, U.S. 
Environmental Protection Agency, Mail Code 6405J, 1200 Pennsylvania 
Ave., NW., 20460.
    (ii) These reports shall indicate the test group, the averaging set, 
the actual U.S. production volume (excluding vehicles produced for sale 
in California), the values required to calculate credits as given in the 
applicable averaging, trading and banking section, and the resulting 
type and number of credits generated/required. Manufacturers shall also 
submit how and where credit surpluses were dispersed (or are to be 
banked) and how and through what means credit deficits were met. Copies 
of contracts related to credit trading must also be included or supplied 
by the broker if applicable. The report shall also include a calculation 
of credit balances to show that net mass emissions balances are within 
those allowed by the emission standards (equal to or greater than a zero 
credit balance). Any credit discount factor described in the applicable 
averaging, trading and banking section must be included as required.
    (iii) The production counts for end-of-year reports shall be based 
on the location of the first point of retail sale (e.g., customer, 
dealer, secondary manufacturer) by the manufacturer.
    (iv) Errors discovered by EPA or the manufacturer in the end-of-year 
report, including changes in the production counts, may be corrected up 
to 180 days subsequent to submission of the end-of-year report. Errors 
discovered by EPA after 180 days shall be corrected if credits are 
reduced. Errors in the manufacturer's favor will not be corrected if 
discovered after the 180 day correction period allowed.
    (j) Failure to submit quarterly or end-of-year reports. Failure by a 
manufacturer participating in the averaging, trading and banking program 
to submit any quarterly or end-of-year report (as applicable) in the 
specified time for all vehicles that are part of an averaging set is a 
violation of section 203(a)(1) of the Clean Air Act (42 U.S.C. 
7522(a)(1)) for such vehicles.
    (k) Failure to submit end-of-year reports for banked credits. 
Failure by a manufacturer generating credits for deposit only in the 
complete heavy-duty vehicle banking program to submit their end-of-year 
reports in the applicable specified time period (i.e., 90 days after the 
end of the model year) shall result in the credits not being available 
for use until such reports are received and reviewed by EPA. Use of 
projected credits pending EPA review will not be permitted in these 
circumstances.
    (l) Quarterly records. Any manufacturer producing a test group 
participating in trading using reserved credits, shall maintain the 
following records on a quarterly basis for each test group in the 
trading subclass:
    (1) The test group;
    (2) The averaging set;
    (3) The actual quarterly and cumulative U.S. production volumes 
excluding vehicles produced for sale in California;
    (4) The values required to calculate credits as given in paragraph 
(c) of this section;
    (5) The resulting type and number of credits generated/required;
    (6) How and where credit surpluses are dispersed; and
    (7) How and through what means credit deficits are met.

[[Page 994]]

    (m) Additional flexibility for complete heavy-duty vehicles. If a 
complete heavy-duty vehicle has a NOX FEL of 0.6 grams per 
mile or lower, a discount of 1.0 may be used in the trading and banking 
credits calculation for NOX described in paragraph (c)(2) of 
this section.
    (n) Early banking for complete heavy-duty vehicles. Provisions set 
forth in paragraphs (a) through (m) of this section apply except as 
specifically stated otherwise in this paragraph (n).
    (1) Early banking eligibility. To be eligible for the early banking 
program described in this paragraph, the following must apply:
    (i) Credits are generated from complete heavy-duty vehicles.
    (ii) During certification, the manufacturer shall declare its intent 
to include specific test groups in the early banking program described 
in this paragraph (n).
    (2) Credit generation and use. (i) Early credits may be generated by 
test groups starting in model year 2000.
    (ii) Credits may only be used for complete heavy-duty vehicles 
subject to chassis-based standards, except as provided by paragraph (o) 
in this section, and all credits shall be subject to discounting and all 
other provisions contained in paragraphs (a) through (m) of this 
section.
    (o) Credit transfers. A manufacturer that elects to comply with 
Option 1 or 2 contained in Sec.86.005-10(f) may transfer credits 
between its complete vehicle averaging set and its heavy-duty Otto-cycle 
engine averaging set as follows:
    (1) Credits earned in model years 2004 (2003 for Option 1) through 
2007 are eligible to be transferred.
    (2) Transferred credits may not be banked for use in model years 
2008 and later. Credits that are transferred but not used prior to model 
year 2008 must be forfeited.
    (3) Prior to transferring credits, a manufacturer must develop a 
methodology to transfer the credits including a conversion factor that 
may be used to convert between chassis-based credits (derived on a grams 
per mile basis) and equivalent engine-based credits (derived on a grams 
per brake horsepower-hour basis). The methodology must be approved by 
EPA prior to the start of the model year in which the credits are to be 
transferred. The conversion factor must provide reasonable certainty 
that the credits are equivalent for the specific vehicle test group(s) 
and engine family(s) involved in the generation and use of the credits.

    Effective Date Note: At 86 FR 34371, June 29, 2021, Sec.86.1817-05 
was amended, effective July 29, 2021.



Sec.86.1817-08  Complete heavy-duty vehicle averaging, trading,
and banking program.

    Section 86.1817-08 includes text that specifies requirements that 
differ from Sec.86.1817-05. Where a paragraph in Sec.86.1817-05 is 
identical and applicable to Sec.86.1817-08, this may be indicated by 
specifying the corresponding paragraph and the statement ``[Reserved]. 
For guidance see Sec.86.1817-05.'' This section does not apply for 
NOX or NMOG + NOX emissions for vehicles certified 
to the Tier 3 standards in Sec.86.1816-18, including those vehicles 
that certify to the Tier 3 standards before model year 2018. See 
Sec. Sec.86.1860 and 86.1861 for provisions that apply for vehicles 
certified to the Tier3 standards.
    (a) through (o) [Reserved]. For guidance see Sec.86.1817-05.
    (p) The following provisions apply for model year 2008 and later 
engines. These provisions apply instead of the provisions of paragraphs 
Sec.86.1817-05 (a) through (o) to the extent that they are in 
conflict.
    (1) Manufacturers of Otto-cycle vehicles may participate in an NMHC 
averaging, banking and trading program to show compliance with the 
standards specified in Sec.86.1806-08. The generation and use of NMHC 
credits are subject to the same provisions in paragraphs Sec.86.1817-
05 (a) through (o) that apply for NOX credits, except as 
otherwise specified in this section.
    (2) NOX or NMHC (or NOX plus NMHC) credits may 
be exchanged between heavy-duty Otto-cycle test groups certified to the 
engine standards of subpart A of this part and heavy-duty Otto-cycle 
test groups certified to the

[[Page 995]]

chassis standards of this subpart, subject to an 0.8 discount factor 
(e.g., 100 grams of NOX credits generated from vehicles would 
be equivalent to 80 grams of NOX credits if they are used in 
the engine program of subpart A of this part, and vice versa). Credits 
that were previously discounted when they were banked according to Sec.
86.1817-05(c), are subject to an additional discount factor of 0.888 
instead of the 0.8 discount factor otherwise required by this paragraph 
(p)(2). This results in a total discount of 0.8 (0.9 x 0.888 = 0.8).
    (3) Credits are to be rounded to the nearest one-hundredth of a 
Megagram.
    (4) To calculate credits relative to the NOX standards 
listed in Sec.86.1816-08 (a)(1)(iv)(A) or (a)(2)(iv)(A) (0.2 or 0.4 
grams per mile, respectively) express the standard and FEL to the 
nearest one-hundredth of a gram per mile prior to calculating the 
credits. Thus, either 0.20 or 0.40 should be used as the value for 
``Std''.
    (5) Credits generated for 2008 and later model year test groups are 
not discounted (except as specified in Sec.86.1817-05(c) and paragraph 
(p)(2) of this section), and do not expire.
    (6) For the purpose of using or generating credits during a phase-in 
of new standards, a manufacturer may elect to split a test group into 
two subgroups: one which uses credits and one which generates credits. 
The manufacturer must indicate in the application for certification that 
the test group is to be split, and may assign the numbers and 
configurations of vehicles within the respective subfamilies at any time 
prior to the submission of the end-of-year report described in Sec.
86.1817-05 (i)(3). Manufacturers certifying a split test group may label 
all of the vehicles within that test group with the same FELs: either 
with a NOX FEL and an NMHC FEL, or with a single 
NOX + NMHC FEL. The FEL(s) on the label will apply for all 
SEA or other compliance testing.
    (7) Vehicles meeting all of the applicable standards of Sec.
86.1816-08 prior to model year 2008 may generate NMHC credits for use by 
2008 or later test groups. Credits are calculated according to Sec.
86.1817-05(c), except that the applicable FEL cap listed in Sec.
86.1816-08(a)(1)(ii)(B) or (2)(ii)(B) applies instead of ``Std'' (the 
applicable standard).

Sec.86.1818-12  Greenhouse gas emission standards for light-duty
vehicles, light-duty trucks, and medium-duty passenger vehicles.

    (a) Applicability. (1) This section contains standards and other 
regulations applicable to the emission of the air pollutant defined as 
the aggregate group of six greenhouse gases: Carbon dioxide, nitrous 
oxide, methane, hydrofluorocarbons, perfluorocarbons, and sulfur 
hexafluoride. This section applies to 2012 and later model year LDV, LDT 
and MDPV, including multi-fuel vehicles, vehicles fueled with 
alternative fuels, hybrid electric vehicles, plug-in hybrid electric 
vehicles, electric vehicles, and fuel cell vehicles. Unless otherwise 
specified, multi-fuel vehicles must comply with all requirements 
established for each consumed fuel. The provisions of this section, 
except paragraph (c), also apply to clean alternative fuel conversions 
as defined in 40 CFR 85.502, of all model year light-duty vehicles, 
light-duty trucks, and medium-duty passenger vehicles. Manufacturers 
that qualify as a small business according to the requirements of Sec.
86.1801-12(j) are exempt from the emission standards in this section. 
Manufacturers that have submitted a declaration for a model year 
according to the requirements of Sec.86.1801-12(k) for which approval 
has been granted by the Administrator are conditionally exempt from the 
emission standards in paragraphs (c) through (e) of this section for the 
approved model year.
    (2) The standards specified in this section apply for testing at 
both low-altitude conditions and high-altitude conditions. However, 
manufacturers must submit an engineering evaluation indicating that 
common calibration approaches are utilized at high altitude instead of 
performing testing for certification, consistent with Sec.86.1829. Any 
deviation from low altitude emission control practices must be included 
in the auxiliary emission control device (AECD) descriptions submitted 
at certification. Any AECD specific to high altitude requires 
engineering

emission data for EPA evaluation to quantify any emission impact and 
determine the validity of the AECD.
    (b) Definitions. For the purposes of this section, the following 
definitions shall apply:
    (1) Passenger automobile means a motor vehicle that is a passenger 
automobile as that term is defined in 49 CFR 523.4.
    (2) Light truck means a motor vehicle that is a non-passenger 
automobile as that term is defined in 49 CFR 523.5.
    (3) Manufacturer has the meaning given by the Department of 
Transportation at 49 CFR 531.4.
    (c) Fleet average CO2 standards for passenger automobiles and light 
trucks. (1) For a given individual model year's production of passenger 
automobiles and light trucks, manufacturers must comply with a full 
useful life fleet average CO2 standard calculated according 
to the provisions of this paragraph (c). Manufacturers must calculate 
separate full useful life fleet average CO2 standards for 
their passenger automobile and light truck fleets, as those terms are 
defined in this section. Each manufacturer's fleet average 
CO2 standards determined in this paragraph (c) shall be 
expressed in whole grams per mile, in the model year specified as 
applicable. Manufacturers eligible for and choosing to participate in 
the Temporary Leadtime Allowance Alternative Standards for qualifying 
manufacturers specified in paragraph (e) of this section shall not 
include vehicles subject to the Temporary Leadtime Allowance Alternative 
Standards in the calculations of their primary passenger automobile or 
light truck standards determined in this paragraph (c). Manufacturers 
shall demonstrate compliance with the applicable standards according to 
the provisions of Sec.86.1865.

    (ii) Calculation of fleet average CO2 standards for light trucks. In 
each model year manufacturers must comply with the CO2 
exhaust emission standard for their light truck fleet, calculated for 
that model year as follows:
    (A) A CO2 target value shall be determined according to 
paragraph (c)(3)(i) of this section for each unique combination of model 
type and footprint value.
    (B) Each CO2 target value, which represents a unique 
combination of model type and footprint value, shall be multiplied by 
the total production of that model type/footprint combination for the 
appropriate model year.
    (C) The resulting products shall be summed, and that sum shall be 
divided by the total production of light trucks in that model year. The 
result shall be rounded to the nearest whole gram per mile. This result 
shall be the applicable fleet average CO2 standard for the 
manufacturer's light truck fleet.
    (4) Emergency vehicles. Emergency vehicles may be excluded from the 
emission standards described in this section. The manufacturer must 
notify the Administrator that they are making such an election in the 
model year reports required under Sec.600.512 of this chapter. Such 
vehicles should be excluded from both the calculation of the fleet 
average standard for a manufacturer under this paragraph (c) and from 
the calculation of the fleet average carbon-related exhaust emissions in 
Sec.600.510-12.
    (d) In-use CO2 exhaust emission standards. The in-use CO2 
exhaust emission standard shall be the combined city/highway carbon-
related exhaust emission value calculated for the appropriate vehicle 
carline/subconfiguration according to the provisions of Sec.600.113-
12(g)(4) of this chapter multiplied by 1.1 and rounded to the nearest 
whole gram per mile. For in-use vehicle carlines/subconfigurations for 
which a combined city/highway carbon-related exhaust emission value was 
not determined under Sec.600.113-12(g)(4) of this chapter, the in-use 
CO2 exhaust emission standard shall be the combined city/
highway carbon-related exhaust emission value calculated according to 
the provisions of Sec.600.208 of this chapter for the vehicle model 
type (except that total model year production data shall be used instead 
of sales projections) multiplied by 1.1 and rounded to

[[Page 999]]

the nearest whole gram per mile. For vehicles that are capable of 
operating on multiple fuels, except plug-in hybrid electric vehicles, a 
separate in-use standard shall be determined for each fuel that the 
vehicle is capable of operating on. These standards apply to in-use 
testing performed by the manufacturer pursuant to regulations at 
Sec. Sec.86.1845 and 86.1846 and to in-use testing performed by EPA.
    (e) Temporary Lead Time Allowance Alternative Standards. (1) The 
interim fleet average CO2 standards in this paragraph (e) are 
optionally applicable to each qualifying manufacturer, where the terms 
``sales'' or ``sold'' as used in this paragraph (e) means vehicles 
produced for U.S. sale, where ``U.S.'' means the states and territories 
of the United States.
    (i) A qualifying manufacturer is a manufacturer with sales of 2009 
model year combined passenger automobiles and light trucks of greater 
than zero and less than 400,000 vehicles that elects to participate in 
the Temporary Leadtime Allowance Alternative Standards described in this 
paragraph (e).
    (A) If a manufacturer sold less than 400,000 but more than zero 2009 
model year combined passenger automobiles and light trucks while under 
the control of another manufacturer, where those 2009 model year 
passenger automobiles and light trucks bore the brand of the producing 
manufacturer, and where the producing manufacturer became independent no 
later than December 31, 2010, the producing manufacturer is a qualifying 
manufacturer.
    (B) In the case where two or more qualifying manufacturers combine 
as the result of merger or the purchase of 50 percent or more of one or 
more companies by another company, and if the combined 2009 model year 
sales of the merged or combined companies is less than 400,000 but more 
than zero (combined passenger automobiles and light trucks), the 
corporate entity formed by the combination of two or more qualifying 
manufacturers shall continue to be a qualifying manufacturer, except the 
provisions of paragraph (e)(1)(i)(D) shall apply in the case where one 
of the merging companies elects to voluntarily opt out of the Temporary 
Leadtime Allowance Alternative Standards as allowed under paragraph 
(e)(1)(iv) of this section. The total number of vehicles that the 
corporate entity is allowed to include under the Temporary Leadtime 
Allowance Alternative Standards shall be determined by paragraph (e)(2) 
or (e)(3) of this section, where sales is the total combined 2009 model 
year sales of all of the merged or combined companies. Vehicles sold by 
the companies that combined by merger/acquisition to form the corporate 
entity that were subject to the Temporary Leadtime Allowance Alternative 
Standards in paragraph (e)(4) of this section prior to the merger/
acquisition shall be combined to determine the remaining number of 
vehicles that the corporate entity may include under the Temporary 
Leadtime Allowance Alternative Standards in this paragraph (e).
    (C) In the case where two or more manufacturers combine as the 
result of merger or the purchase of 50 percent or more of one or more 
companies by another company, and if the combined 2009 model year sales 
of the merged or combined companies is equal to or greater than 400,000 
(combined passenger automobiles and light trucks), the new corporate 
entity formed by the combination of two or more manufacturers is not a 
qualifying manufacturer. Such a manufacturer shall meet the emission 
standards in paragraph (c) of this section beginning with the model year 
that is numerically two years greater than the calendar year in which 
the merger/acquisition(s) took place.
    (D) In the case where two or more manufacturers combine as the 
result of merger or the purchase of 50 percent or more of one or more 
companies by another company, where one of the manufacturers chooses to 
voluntarily opt out of the Temporary Leadtime Allowance Alternative 
Standards under the provisions of paragraph (e)(1)(iv) of this section, 
the new corporate entity formed by the combination of two or more 
manufacturers is not a qualifying manufacturer. Such a manufacturer 
shall meet the emission standards in paragraph (c) of this section 
beginning

[[Page 1000]]

with the model year that is numerically two years greater than the 
calendar year in which the merger/acquisition(s) took place. If one or 
more of the merged or combined manufacturers was complying with the 
Temporary Leadtime Allowance Alternative Standards prior to the merger/
combination, that manufacturer is no longer eligible for the Temporary 
Leadtime Allowance Alternative Standards beginning with the model year 
that is numerically two years greater than the calendar year in which 
the merger/acquisition(s) took place. The cumulative number of vehicles 
that such a manufacturer may include in the Temporary Leadtime Allowance 
Alternative Standards, including those that were included by all merged 
manufacturers prior to the merger/acquisition, is limited to 100,000.
    (ii) For the purposes of making the determination in paragraph 
(e)(1)(i) of this section, ``manufacturer'' shall mean that term as 
defined at 49 CFR 531.4 and as that definition was applied to the 2009 
model year for the purpose of determining compliance with the 2009 
corporate average fuel economy standards at 49 CFR parts 531 and 533.
    (iii) A qualifying manufacturer may not use these Temporary Leadtime 
Allowance Alternative Standards until they have used all available 
banked credits and/or credits available for transfer accrued under Sec.
86.1865-12(k). A qualifying manufacturer with a net positive credit 
balance calculated under Sec.86.1865-12(k) in any model year after 
considering all available credits either generated, carried forward from 
a prior model year, transferred from other averaging sets, or obtained 
from other manufacturers, may not use these Temporary Leadtime Allowance 
Alternative Standards in such model year.
    (iv) In the event of a merger, acquisition, or combination with 
another manufacturer, a qualifying manufacturer that has not certified 
any vehicles to the Temporary Leadtime Allowance Alternative Standards 
in any model year may voluntarily opt out of the Temporary Leadtime 
Allowance Alternative Standards. A manufacturer making this election 
must notify EPA in writing of their intent prior to the end of the model 
year in which a merger or combination with another manufacturer becomes 
effective. The notification must indicate that the manufacturer is 
electing to not use the Temporary Leadtime Allowance Alternative 
Standards in any model year, and that any manufacturers that are either 
purchased by or merged with the manufacturer making this election must 
also meet the emission standards in paragraph (c) of this section 
beginning with the model year that is numerically two years greater than 
the calendar year in which the merger/acquisition(s) took place.
    (2) Qualifying manufacturers may select any combination of 2012 
through 2015 model year passenger automobiles and/or light trucks to 
include under the Temporary Leadtime Allowance Alternative Standards 
determined in this paragraph (e) up to a cumulative total of 100,000 
vehicles. Vehicles selected to comply with these standards shall not be 
included in the calculations of the manufacturer's fleet average 
standards under paragraph (c) of this section.
    (3)(i) Qualifying manufacturers with sales of 2009 model year 
combined passenger automobiles and light trucks in the United States of 
greater than zero and less than 50,000 vehicles may select any 
combination of 2012 through 2015 model year passenger automobiles and/or 
light trucks to include under the Temporary Leadtime Allowance 
Alternative Standards determined in this paragraph (e) up to a 
cumulative total of 200,000 vehicles, and additionally may select up to 
50,000 2016 model year vehicles to include under the Temporary Leadtime 
Allowance Alternative Standards determined in this paragraph (e). To be 
eligible for the provisions of this paragraph (e)(3) qualifying 
manufacturers must provide annual documentation of good-faith efforts 
made by the manufacturer to purchase credits from other manufacturers. 
Without such documentation, the manufacturer may use the Temporary 
Leadtime Allowance Alternative Standards according to the provisions of 
paragraph (e)(2) of this section, and the provisions of this paragraph 
(e)(3) shall not apply. Vehicles selected to

[[Page 1001]]

comply with these standards shall not be included in the calculations of 
the manufacturer's fleet average standards under paragraph (c) of this 
section.
    (ii) Manufacturers that qualify in the 2016 model year for the 
expanded Temporary Leadtime Allowance Alternative Standards described in 
paragraph (e)(3)(i) of this section, may, subject to certain 
restrictions, use an alternative compliance schedule that provides 
additional lead time to meet the standards in paragraph (c) of this 
section for the 2017 through 2020 model years.
    (A) The alternative compliance schedule is as follows. In lieu of 
the standards in paragraph (c) of this section that would otherwise be 
applicable to the model year shown in the first column of the table 
below, a qualifying manufacturer may comply with the standards in 
paragraph (c) of this section determined for the model year shown in the 
second column of the table. In the 2021 and later model years the 
manufacturer must meet the standards designated for each model year in 
paragraph (c) of this section.

------------------------------------------------------------------------
             Model year                      Applicable standards

------------------------------------------------------------------------

    (B) A manufacturer using the alternative compliance schedule in 
paragraph (e)(3)(ii) of this section may not sell or otherwise transfer 
credits generated in years when the alternative phase-in is used to 
other manufacturers. Other provisions in Sec.86.1865 regarding credit 
banking, deficit carry-forward, and within-manufacturer transfers across 
fleets apply.
    (4) To calculate the applicable Temporary Leadtime Allowance 
Alternative Standards, qualifying manufacturers shall determine the 
fleet average standard separately for the passenger automobiles and 
light trucks selected by the manufacturer to be subject to the Temporary 
Leadtime Allowance Alternative Standards, subject to the limitations 
expressed in paragraphs (e)(1) through (3) of this section.
    (i) The Temporary Leadtime Allowance Alternative Standard applicable 
to qualified passenger automobiles as defined in Sec.600.002-08 of 
this chapter shall be the standard calculated using the provisions of 
paragraph (c)(2)(ii) of this section for the appropriate model year 
multiplied by 1.25 and rounded to the nearest whole gram per mile. For 
the purposes of applying paragraph (c)(2)(ii) of this section to 
determine the standard, the passenger automobile fleet shall be limited 
to those passenger automobiles subject to the Temporary Leadtime 
Allowance Alternative Standard.
    (ii) The Temporary Leadtime Allowance Alternative Standard 
applicable to qualified light trucks (i.e. non-passenger automobiles as 
defined in Sec.600.002-08 of this chapter) shall be the standard 
calculated using the provisions of paragraph (c)(3)(ii) of this section 
for the appropriate model year multiplied by 1.25 and rounded to the 
nearest whole gram per mile. For the purposes of applying paragraph 
(c)(3)(ii) of this section to determine the standard, the light truck 
fleet shall be limited to those light trucks subject to the Temporary 
Leadtime Allowance Alternative Standard.
    (5) Manufacturers choosing to optionally apply these standards are 
subject to the restrictions on credit banking and trading specified in 
Sec.86.1865-12.
    (f) Nitrous oxide (N2O) and methane (CH4) 
exhaust emission standards for passenger automobiles and light trucks. 
Each manufacturer's fleet of combined passenger automobiles and light 
trucks must comply with N2O and CH4 standards 
using either the provisions of paragraph (f)(1), (2), or (3) of this 
section. Except with prior EPA approval, a manufacturer may not use the 
provisions of both paragraphs (f)(1) and (2) of this section in a model 
year. For example, a manufacturer may not use the provisions of 
paragraph (f)(1) of this section for their passenger automobile fleet 
and the provisions of paragraph (f)(2) for their light truck fleet in 
the same model year. The manufacturer may use the provisions of both 
paragraphs (f)(1) and (3) of this section in a model year. For example, 
a manufacturer may meet the N2O standard in paragraph 
(f)(1)(i) of this section and an alternative CH4 standard 
determined under paragraph (f)(3) of this section. Vehicles certified 
using the

[[Page 1002]]

N2O data submittal waiver provisions of Sec.
86.1829(b)(1)(iii)(G) are not required to be tested for N2O 
under the in-use testing programs required by Sec.86.1845 and Sec.
86.1846.
    (1) Standards applicable to each test group. (i) Exhaust emissions 
of nitrous oxide (N2O) shall not exceed 0.010 grams per mile 
at full useful life, as measured according to the Federal Test Procedure 
(FTP) described in subpart B of this part. Manufacturers may optionally 
determine an alternative N2O standard under paragraph (f)(3) 
of this section. (ii) Exhaust emissions of methane (CH4) 
shall not exceed 0.030 grams per mile at full useful life, as measured 
according to the Federal Test Procedure (FTP) described in subpart B of 
this part. Manufacturers may optionally determine an alternative 
CH4 standard under paragraph (f)(3) of this section.
    (2) Include N 2O and CH4 in fleet averaging 
program. Manufacturers may elect to not meet the emission standards in 
paragraph (f)(1) of this section. Manufacturers making this election 
shall include N2O and CH4 emissions in the 
determination of their fleet average carbon-related exhaust emissions, 
as calculated in 40 CFR part 600, subpart F. Manufacturers using this 
option must include both N2O and CH4 full useful 
life values in the fleet average calculations for passenger automobiles 
and light trucks. Use of this option will account for N2O and 
CH4 emissions within the carbon-related exhaust emission 
value determined for each model type according to the provisions of 40 
CFR part 600. This option requires the determination of full useful life 
emission values for both the Federal Test Procedure and the Highway Fuel 
Economy Test. Manufacturers selecting this option are not required to 
demonstrate compliance with the standards in paragraph (f)(1) of this 
section.
    (3) Optional use of alternative N2O and/or CH4 
standards. Manufacturers may select an alternative standard applicable 
to a test group, for either N2O or CH4, or both. 
For example, a manufacturer may choose to meet the N2O 
standard in paragraph (f)(1)(i) of this section and an alternative 
CH4 standard in lieu of the standard in paragraph (f)(1)(ii) 
of this section. The alternative standard for each pollutant must be 
greater than the applicable exhaust emission standard specified in 
paragraph (f)(1) of this section. Alternative N2O and 
CH4 standards apply to emissions measured according to the 
Federal Test Procedure (FTP) described in Subpart B of this part for the 
full useful life, and become the applicable certification and in-use 
emission standard(s) for the test group. Manufacturers using an 
alternative standard for N2O and/or CH4 must 
calculate emission debits according to the provisions of paragraph 
(f)(4) of this section for each test group/alternative standard 
combination. Debits must be included in the calculation of total credits 
or debits generated in a model year as required under Sec.86.1865-
12(k)(5). For flexible fuel vehicles (or other vehicles certified for 
multiple fuels) you must meet these alternative standards when tested on 
any applicable test fuel type.
    (4) CO2-equivalent debits. CO2-equivalent 
debits for test groups using an alternative N2O and/or 
CH4 standard as determined under paragraph (f)(3) of this 
section shall be calculated according to the following equation and 
rounded to the nearest whole megagram:

Debits = [GWP x (Production) x (AltStd--Std) x VLM] / 1,000,000

Where:

Debits = CO2-equivalent debits for N2O or 
          CH4, in Megagrams, for a test group using an 
          alternative N2O or CH4 standard, rounded 
          to the nearest whole Megagram;
GWP = 25 if calculating CH4 debits and 298 if calculating 
          N2O debits;
Production = The number of vehicles of that test group domestically 
          produced plus those imported as defined in Sec.600.511 of 
          this chapter;
AltStd = The alternative standard (N2O or CH4) 
          selected by the manufacturer under paragraph (f)(3) of this 
          section;
Std = The exhaust emission standard for N2O or CH4 
          specified in paragraph (f)(1) of this section; and
VLM = 195,264 for passenger automobiles and 225,865 for light trucks.

    (g) Alternative fleet average standards for manufacturers with 
limited U.S. sales. Manufacturers meeting the criteria in this paragraph 
(g) may request that

[[Page 1003]]

the Administrator establish alternative fleet average CO2 
standards that would apply instead of the standards in paragraph (c) of 
this section. The provisions of this paragraph (g) are applicable only 
to the 2017 and later model years. A manufacturer that has sought and 
received EPA approval for alternative standards for the 2017 model year 
may, at their option, choose to comply with those standards in the 2015 
and 2016 model years in lieu of requesting a conditional exemption under 
Sec.86.1801(k).
    (1) Eligibility for alternative standards. Eligibility as determined 
in this paragraph (g) shall be based on the total sales of combined 
passenger automobiles and light trucks. The terms ``sales'' and ``sold'' 
as used in this paragraph (g) shall mean vehicles produced for U.S. 
sale, where ``U.S.'' means the states and territories of the United 
States. For the purpose of determining eligibility the sales of related 
companies shall be aggregated according to the provisions of Sec.
86.1838-01(b)(3), or, if a manufacturer has been granted operational 
independence status under Sec.86.1838(d), eligibility shall be based 
on vehicle production of that manufacturer. To be eligible for 
alternative standards established under this paragraph (g), the 
manufacturer's average sales for the three most recent consecutive model 
years must remain below 5,000. If a manufacturer's average sales for the 
three most recent consecutive model years exceeds 4999, the manufacturer 
will no longer be eligible for exemption and must meet applicable 
emission standards starting with the model year according to the 
provisions in this paragraph (g)(1).
    (i) If a manufacturer's average sales for three consecutive model 
years exceeds 4999, and if the increase in sales is the result of 
corporate acquisitions, mergers, or purchase by another manufacturer, 
the manufacturer shall comply with the emission standards described in 
paragraph (c) of this section, as applicable, beginning with the first 
model year after the last year of the three consecutive model years.
    (ii) If a manufacturer's average sales for three consecutive model 
years exceeds 4999 and is less than 50,000, and if the increase in sales 
is solely the result of the manufacturer's expansion in vehicle 
production (not the result of corporate acquisitions, mergers, or 
purchase by another manufacturer), the manufacturer shall comply with 
the emission standards described in paragraph (c), of this section, as 
applicable, beginning with the second model year after the last year of 
the three consecutive model years.
    (2) Requirements for new entrants into the U.S. market. New entrants 
are those manufacturers without a prior record of automobile sales in 
the United States and without prior certification to (or exemption from, 
under Sec.86.1801-12(k)) greenhouse gas emission standards in Sec.
86.1818-12. In addition to the eligibility requirements stated in 
paragraph (g)(1) of this section, new entrants must meet the following 
requirements:
    (i) In addition to the information required under paragraph (g)(4) 
of this section, new entrants must provide documentation that shows a 
clear intent by the company to actually enter the U.S. market in the 
years for which alternative standards are requested. Demonstrating such 
intent could include providing documentation that shows the 
establishment of a U.S. dealer network, documentation of work underway 
to meet other U.S. requirements (e.g., safety standards), or other 
information that reasonably establishes intent to the satisfaction of 
the Administrator.
    (ii) Sales of vehicles in the U.S. by new entrants must remain below 
5,000 vehicles for the first three model years in the U.S. market, and 
in subsequent years the average sales for any three consecutive years 
must remain below 5,000 vehicles. Vehicles sold in violation of these 
limits within the first five model years will be considered not covered 
by the certificate of conformity and the manufacturer will be subject to 
penalties on an individual-vehicle basis for sale of vehicles not 
covered by a certificate. In addition, violation of these limits will 
result in loss of eligibility for alternative standards until such point 
as the manufacturer demonstrates two consecutive model years of sales 
below 5,000 automobiles. After the first five model years, the 
eligibility provisions in paragraph (g)(1) of

[[Page 1004]]

this section apply, where violating the sales thresholds is no longer a 
violation of the condition on the certificate, but is instead grounds 
for losing eligibility for alternative standards.
    (iii) A manufacturer with sales in the most recent model year of 
less than 5,000 automobiles, but where prior model year sales were not 
less than 5,000 automobiles, is eligible to request alternative 
standards under this paragraph (g). However, such a manufacturer will be 
considered a new entrant and subject to the provisions regarding new 
entrants in this paragraph (g), except that the requirement to 
demonstrate an intent to enter the U.S. market in paragraph (g)(2)(i) of 
this section shall not apply.
    (3) How to request alternative fleet average standards. Eligible 
manufacturers may petition for alternative standards for up to five 
consecutive model years if sufficient information is available on which 
to base such standards.
    (i) To request alternative standards starting with the 2017 model 
year, eligible manufacturers must submit a completed application no 
later than July 30, 2013.
    (ii) To request alternative standards starting with a model year 
after 2017, eligible manufacturers must submit a completed request no 
later than 36 months prior to the start of the first model year to which 
the alternative standards would apply.
    (iii) The request must contain all the information required in 
paragraph (g)(4) of this section, and must be signed by a chief officer 
of the company. If the Administrator determines that the content of the 
request is incomplete or insufficient, the manufacturer will be notified 
and given an additional 30 days to amend the request.
    (4) Data and information submittal requirements. Eligible 
manufacturers requesting alternative standards under this paragraph (g) 
must submit the following information to the Environmental Protection 
Agency. The Administrator may request additional information as she 
deems appropriate. The completed request must be sent to the 
Environmental Protection Agency at the following address: Director, 
Compliance and Innovative Strategies Division, U.S. Environmental 
Protection Agency, 2000 Traverwood Drive, Ann Arbor, Michigan 48105.
    (i) Vehicle model and fleet information. (A) The model years to 
which the requested alternative standards would apply, limited to five 
consecutive model years.
    (B) Vehicle models and projections of production volumes for each 
model year.
    (C) Detailed description of each model, including the vehicle type, 
vehicle mass, power, footprint, powertrain, and expected pricing.
    (D) The expected production cycle for each model, including new 
model introductions and redesign or refresh cycles.
    (ii) Technology evaluation information. (A) The CO2 
reduction technologies employed by the manufacturer on each vehicle 
model, or projected to be employed, including information regarding the 
cost and CO2 -reducing effectiveness. Include technologies 
that improve air conditioning efficiency and reduce air conditioning 
system leakage, and any ``off-cycle'' technologies that potentially 
provide benefits outside the operation represented by the Federal Test 
Procedure and the Highway Fuel Economy Test.
    (B) An evaluation of comparable models from other manufacturers, 
including CO2 results and air conditioning credits generated 
by the models. Comparable vehicles should be similar, but not 
necessarily identical, in the following respects: vehicle type, 
horsepower, mass, power-to-weight ratio, footprint, retail price, and 
any other relevant factors. For manufacturers requesting alternative 
standards starting with the 2017 model year, the analysis of comparable 
vehicles should include vehicles from the 2012 and 2013 model years, 
otherwise the analysis should at a minimum include vehicles from the 
most recent two model years.
    (C) A discussion of the CO2-reducing technologies 
employed on vehicles offered outside of the U.S. market but not 
available in the U.S., including a discussion as to why those vehicles 
and/or technologies are not being used to achieve CO2 
reductions for vehicles in the U.S. market.
    (D) An evaluation, at a minimum, of the technologies projected by 
the Environmental Protection Agency in a final

[[Page 1005]]

rulemaking as those technologies likely to be used to meet greenhouse 
gas emission standards and the extent to which those technologies are 
employed or projected to be employed by the manufacturer. For any 
technology that is not projected to be fully employed, explain why this 
is the case.
    (iii) Alternative fleet average CO2 standards. (A) The 
most stringent CO2 level estimated to be feasible for each 
model, in each model year, and the technological basis for this 
estimate.
    (B) For each model year, a projection of the lowest feasible sales-
weighted fleet average CO2 value, separately for passenger 
automobiles and light trucks, and an explanation demonstrating that 
these projections are reasonable.
    (C) A copy of any application, data, and related information 
submitted to NHTSA in support of a request for alternative Corporate 
Average Fuel Economy standards filed under 49 CFR Part 525.
    (iv) Information supporting eligibility. (A) U.S. sales for the 
three previous model years and projected sales for the model years for 
which the manufacturer is seeking alternative standards.
    (B) Information regarding ownership relationships with other 
manufacturers, including details regarding the application of the 
provisions of Sec.86.1838-01(b)(3) regarding the aggregation of sales 
of related companies,
    (5) Alternative standards. Upon receiving a complete application, 
the Administrator will review the application and determine whether an 
alternative standard is warranted. If the Administrator judges that an 
alternative standard is warranted, the Administrator will publish a 
proposed determination in the Federal Register to establish alternative 
standards for the manufacturer that the Administrator judges are 
appropriate. Following a 30 day public comment period, the Administrator 
will issue a final determination establishing alternative standards for 
the manufacturer. If the Administrator does not establish alternative 
standards for an eligible manufacturer prior to 12 months before the 
first model year to which the alternative standards would apply, the 
manufacturer may request an extension of the exemption under Sec.
86.1801-12(k) or an extension of previously approved alternative 
standards, whichever may apply.
    (6) Restrictions on credit trading. Manufacturers subject to 
alternative standards approved by the Administrator under this paragraph 
(g) may not trade credits to another manufacturer. Transfers between car 
and truck fleets within the manufacturer are allowed, and the carry-
forward provisions for credits and deficits apply.
    (h) Mid-term evaluation of standards. No later than April 1, 2018, 
the Administrator shall determine whether the standards established in 
paragraph (c) of this section for the 2022 through 2025 model years are 
appropriate under section 202(a) of the Clean Air Act, in light of the 
record then before the Administrator. An opportunity for public comment 
shall be provided before making such determination. If the Administrator 
determines they are not appropriate, the Administrator shall initiate a 
rulemaking to revise the standards, to be either more or less stringent 
as appropriate.
    (1) In making the determination required by this paragraph (h), the 
Administrator shall consider the information available on the factors 
relevant to setting greenhouse gas emission standards under section 
202(a) of the Clean Air Act for model years 2022 through 2025, including 
but not limited to:
    (i) The availability and effectiveness of technology, and the 
appropriate lead time for introduction of technology;
    (ii) The cost on the producers or purchasers of new motor vehicles 
or new motor vehicle engines;
    (iii) The feasibility and practicability of the standards;
    (iv) The impact of the standards on reduction of emissions, oil 
conservation, energy security, and fuel savings by consumers;
    (v) The impact of the standards on the automobile industry;
    (vi) The impacts of the standards on automobile safety;
    (vii) The impact of the greenhouse gas emission standards on the 
Corporate Average Fuel Economy standards and a national harmonized 
program; and

[[Page 1006]]

    (viii) The impact of the standards on other relevant factors.
    (2) The Administrator shall make the determination required by this 
paragraph (h) based upon a record that includes the following:
    (i) A draft Technical Assessment Report addressing issues relevant 
to the standard for the 2022 through 2025 model years;
    (ii) Public comment on the draft Technical Assessment Report;
    (iii) Public comment on whether the standards established for the 
2022 through 2025 model years are appropriate under section 202(a) of 
the Clean Air Act; and

Sec.86.1819-14  Greenhouse gas emission standards for heavy-duty 
vehicles.

    This section describes exhaust emission standards for 
CO2, CH4, and N2O for heavy-duty 
vehicles. The standards of this section apply for model year 2014 and 
later vehicles that are chassis-certified with respect to criteria 
pollutants under this subpart S. Additional heavy-duty vehicles may be 
optionally subject to the standards of this section as allowed under 
paragraph (j) of this section. Any heavy-duty vehicles not subject to 
standards under this section are instead subject to greenhouse gas 
standards under 40 CFR part 1037, and engines installed in these 
vehicles are subject to standards under 40 CFR part 1036. If you are not 
the engine manufacturer, you must notify the engine manufacturer that 
its engines are subject to 40 CFR part 1036 if you intend to use their 
engines in vehicles that are not subject to standards under this 
section. Vehicles produced by small businesses may be excluded from the 
standards of this section as described in paragraph (k)(5) of this 
section.
    (a) Fleet-average CO2 emission standards. Fleet-average 
CO2 emission standards apply for the full useful life for 
each manufacturer as follows:
    (1) Calculate a work factor, WF, for each vehicle subconfiguration 
(or group of subconfigurations as allowed under paragraph (a)(4) of this 
section), rounded to the nearest pound, using the following equation:

    WF = 0.75 x (GVWR - Curb Weight + xwd) + 0.25 x (GCWR - GVWR)

Where:

xwd = 500 pounds if the vehicle has four-wheel drive or all-wheel drive; 
          xwd = 0 pounds for all other vehicles.

    (2) Using the appropriate work factor, calculate a target value for 
each vehicle subconfiguration (or group of subconfigurations as allowed 
under paragraph (a)(4) of this section) you produce using one of the 
following equations, or the phase-in provisions in paragraph (k)(4) of 
this section, rounding to the nearest whole g/mile:
    (i) For model year 2027 and later vehicles with spark-ignition 
engines: CO2 Target (g/mile) = 0.0369 x WF + 284
    (ii) For model year 2027 and later vehicles with compression-
ignition engines or with no engines (such as electric vehicles and fuel 
cell vehicles): CO2 Target (g/mile) = 0.0348 x WF + 268
    (3) Calculate a production-weighted average of the target values and 
round it to the nearest whole g/mile. This is your fleet-average 
standard. All vehicles subject to the standards of this section form a 
single averaging set. Use the following equation to calculate your 
fleet-average standard from the target value for each vehicle 
subconfiguration (Targeti) and U.S.-directed production 
volume of each vehicle subconfiguration for the given model year 
(Volumei):

[[Page 1007]]

    (4) You may group subconfigurations within a configuration together 
for purposes of calculating your fleet-average standard as follows:
    (i) You may group together subconfigurations that have the same 
equivalent test weight (ETW), GVWR, and GCWR. Calculate your work factor 
and target value assuming a curb weight equal to two times ETW minus 
GVWR.
    (ii) You may group together other subconfigurations if you use the 
lowest target value calculated for any of the subconfigurations.
    (5) The standards specified in this section apply for testing at 
both low-altitude conditions and high-altitude conditions. However, 
manufacturers must submit an engineering evaluation indicating that 
common calibration approaches are utilized at high altitude instead of 
performing testing for certification, consistent with Sec.86.1829. Any 
deviation from low altitude emission control practices must be included 
in the auxiliary emission control device (AECD) descriptions submitted 
at certification. Any AECD specific to high altitude requires 
engineering emission data for EPA evaluation to quantify any emission 
impact and determine the validity of the AECD.
    (b) Production and in-use CO2 standards. Each vehicle you 
produce that is subject to the standards of this section has an ``in-
use'' CO2 standard that is calculated from your test result 
and that applies for selective enforcement audits and in-use testing. 
This in-use CO2 standard for each vehicle is equal to the 
applicable deteriorated emission level multiplied by 1.10 and rounded to 
the nearest whole g/mile.
    (c) N2O and CH4 standards. Except as allowed under this paragraph 
(c), all vehicles subject to the standards of this section must comply 
with an N2O standard of 0.05 g/mile and a CH4 
standard of 0.05 g/mile when calculated according to the provisions of 
paragraph (d)(4) of this section. You may specify CH4 and/or 
N2O alternative standards using CO2 emission 
credits instead of these otherwise applicable emission standards for one 
or more test groups. To do this, calculate the CH4 and/or 
N2O emission credits needed (negative credits) using the 
equation in this paragraph (c) based on the FEL(s) you specify for your 
vehicles during certification. You must adjust the calculated emissions 
by the global warming potential (GWP): GWP equals 34 for CH4 
from model year 2021 and later vehicles, 25 for CH4 from 
earlier vehicles, and 298 for N2O. This means, for example, 
that you must use 298 Mg of positive CO2 credits to offset 1 
Mg of negative N2O credits. Note that Sec.86.1818-12(f) 
does not apply for vehicles subject to the standards of this section. 
Calculate credits using the following equation, rounded to the nearest 
whole number:

CO2 Credits Needed (Mg) = [(FEL - Std) x (U.S.-directed 
production volume) x (Useful Life)] x (GWP) / 1,000,000

    (d) Compliance provisions. The following compliance provisions apply 
instead of other provisions described in this subpart S:
    (1) The CO2 standards of this section apply with respect 
to CO2 emissions, not with respect to carbon-related exhaust 
emissions (CREE).
    (2) The following general credit provisions apply:
    (i) Credits you generate under this section may be used only to 
offset credit deficits under this section. You may bank credits for use 
in a future model year in which your average CO2 level 
exceeds the standard. You may trade credits to another manufacturer 
according to Sec.86.1865-12(k)(8). Before you bank or trade credits, 
you must apply any available credits to offset a deficit if the deadline 
to offset that credit deficit has not yet passed.
    (ii) Vehicles subject to the standards of this section are included 
in a single greenhouse gas averaging set separate from any averaging set 
otherwise included in this subpart S.

[[Page 1008]]

    (iii) Banked CO2 credits keep their full value for five 
model years after the year in which they were generated. Unused credits 
may not be used for more than five model years after the model year in 
which the credits are generated.
    (3) Special credit and incentive provisions related to air 
conditioning in Sec. Sec.86.1867 and 86.1868 do not apply for vehicles 
subject to the standards of this section.
    (4) Measure emissions using the procedures of subpart B of this part 
and 40 CFR part 1066. Determine separate emission results for the 
Federal Test Procedure (FTP) described in 40 CFR 1066.801(c)(1) and the 
Highway Fuel Economy Test (HFET) described in 40 CFR 1066.801(c)(3). 
Calculate composite emission results from these two test cycles for 
demonstrating compliance with the CO2, N2O, and 
CH4 standards based on a weighted average of the FTP (55%) 
and HFET (45%) emission results. Note that this differs from the way the 
criteria pollutant standards apply.
    (5) Apply an additive deterioration factor of zero to measured 
CO2 emissions unless good engineering judgment indicates that 
emissions are likely to deteriorate in use. Use good engineering 
judgment to develop separate deterioration factors for N2O 
and CH4.
    (6) Credits are calculated using the useful life value (in miles) in 
place of ``vehicle lifetime miles'' as specified in Sec.86.1865. 
Calculate a total credit or debit balance in a model year by adding 
credits and debits from Sec.86.1865-12(k)(4), subtracting any 
CO2-equivalent debits for N2O or CH4 
calculated according to paragraph (c) of this section, and adding any of 
the following credits:
    (i) Off-cycle technology credits according to paragraph (d)(13) of 
this section.
    (ii) Early credits from vehicles certified under paragraph (k)(2) of 
this section.
    (iii) Advanced-technology credits according to paragraph (k)(7) of 
this section.
    (7) [Reserved]
    (8) The provisions of Sec.86.1818 do not apply.
    (9) Calculate your fleet-average emission rate consistent with good 
engineering judgment and the provisions of Sec.86.1865. The following 
additional provisions apply:
    (i) Unless we approve a lower number, you must test at least ten 
subconfigurations. If you produce more than 100 subconfigurations in a 
given model year, you must test at least ten percent of your 
subconfigurations. For purposes of this paragraph (d)(9)(i), count 
carryover tests, but do not include analytically derived CO2 
emission rates, data substitutions, or other untested allowances. We may 
approve a lower number of tests for manufacturers that have limited 
product offerings, or low sales volumes. Note that good engineering 
judgment and other provisions of this part may require you to test more 
subconfigurations than these minimum values.
    (ii) The provisions of paragraph (g) of this section specify how you 
may use analytically derived CO2 emission rates.
    (iii) At least 90 percent of final production volume at the 
configuration level must be represented by test data (real, data 
substituted, or analytical).
    (iv) Perform fleet-average CO2 calculations as described 
in Sec.86.1865 and 40 CFR part 600, with the following exceptions:
    (A) Use CO2 emissions values for all test results, 
intermediate calculations, and fleet average calculations instead of the 
carbon-related exhaust emission (CREE) values specified in this subpart 
S and 40 CFR part 600.
    (B) Perform intermediate CO2 calculations for 
subconfigurations within each configuration using the subconfiguration 
and configuration definitions in paragraph (d)(12) of this section.
    (C) Perform intermediate CO2 calculations for 
configurations within each test group and transmission type (instead of 
configurations within each base level and base levels within each model 
type). Use the configuration definition in paragraph (d)(12)(i) of this 
section.
    (D) Do not perform intermediate CO2 calculations for each 
base level or for each model type. Base level and model

[[Page 1009]]

type CO2 calculations are not applicable to heavy-duty 
vehicles subject to standards in this section.
    (E) Determine fleet average CO2 emissions for heavy-duty 
vehicles subject to standards in this section as described in 40 CFR 
600.510-12(j), except that the calculations must be performed on the 
basis of test group and transmission type (instead of the model-type 
basis specified in the light-duty vehicle regulations), and the 
calculations for dual-fuel, multi-fuel, and flexible-fuel vehicles must 
be consistent with the provisions of paragraph (d)(10)(i) of this 
section.
    (10) For dual-fuel, multi-fuel, and flexible-fuel vehicles, perform 
exhaust testing on each fuel type (for example, gasoline and E85).
    (i) For your fleet-average calculations in model year 2016 and 
later, use either the conventional-fueled CO2 emission rate 
or a weighted average of your emission results as specified in 40 CFR 
600.510-12(k) for light-duty trucks. For your fleet-average calculations 
before model year 2016, apply an equal weighting of CO2 
emission results from alternative and conventional fuels.
    (ii) If you certify to an alternate standard for N2O or 
CH4 emissions, you may not exceed the alternate standard when 
tested on either fuel.
    (11) Test your vehicles with an equivalent test weight based on its 
Adjusted Loaded Vehicle Weight (ALVW). Determine equivalent test weight 
from the ALVW as specified in 40 CFR 1066.805; round ALVW values above 
14,000 pounds to the nearest 500 pound increment.
    (12) The following definitions apply for the purposes of this 
section:
    (i) Configuration means a subclassification within a test group 
based on engine code, transmission type and gear ratios, final drive 
ratio, and other parameters we designate. Engine code means the 
combination of both ``engine code'' and ``basic engine'' as defined in 
40 CFR 600.002.
    (ii) Subconfiguration means a unique combination within a vehicle 
configuration (as defined in this paragraph (d)(12)) of equivalent test 
weight, road-load horsepower, and any other operational characteristics 
or parameters that we determine may significantly affect CO2 
emissions within a vehicle configuration. Note that for vehicles subject 
to standards of this section, equivalent test weight (ETW) is based on 
the ALVW of the vehicle as outlined in paragraph (d)(11) of this 
section.
    (13) This paragraph (d)(13) applies for CO2 reductions 
resulting from technologies that were not in common use before 2010 that 
are not reflected in the specified test procedures. While you are not 
required to prove that such technologies were not in common use with 
heavy-duty vehicles before model year 2010, we will not approve your 
request if we determine they do not qualify. These may be described as 
off-cycle or innovative technologies. We may allow you to generate 
emission credits consistent with the provisions of Sec.86.1869-12(c) 
and (d). The 5-cycle methodology is not presumed to be preferred over 
alternative methodologies described in Sec.86.1869-12(d).
    (14) You must submit pre-model year reports before you submit your 
applications for certification for a given model year. Unless we specify 
otherwise, include the information specified for pre-model year reports 
in 49 CFR 535.8.
    (15) You must submit a final report within 90 days after the end of 
the model year. Unless we specify otherwise, include applicable 
information identified in Sec.86.1865-12(l), 40 CFR 600.512, and 49 
CFR 535.8(e). The final report must include at least the following 
information:
    (i) Model year.
    (ii) Applicable fleet-average CO2 standard.
    (iii) Calculated fleet-average CO2 value and all the 
values required to calculate the CO2 value.
    (iv) Number of credits or debits incurred and all values required to 
calculate those values.
    (v) Resulting balance of credits or debits.
    (vi) N2O emissions.
    (vii) CH4 emissions.
    (viii) Total and percent leakage rates under paragraph (h) of this 
section.
    (16) You may apply the provisions for delegated assembly as 
described in 40 CFR 1037.621.
    (17) You may calculate emission rates for weight increments less 
than

[[Page 1010]]

the 500 pound increment specified for test weight. This does not change 
the applicable test weights.
    (i) Use the ADC equation in paragraph (g) of this section to adjust 
your emission rates for vehicles in increments of 50, 100, or 250 pounds 
instead of the 500 test-weight increments. Adjust emissions to the 
midpoint of each increment. This is the equivalent emission weight. For 
example, vehicles with a test weight basis of 11,751 to 12,250 pounds 
(which have an equivalent test weight of 12,000 pounds) could be 
regrouped into 100 pound increments as follows:

------------------------------------------------------------------------
                                            Equivalent
            Test weight basis                emission       Equivalent
                                              weight        test weight
------------------------------------------------------------------------
11,751-11,850...........................          11,800          12,000
11,851-11,950...........................          11,900          12,000
11,951-12,050...........................          12,000          12,000
12,051-12,150...........................          12,100          12,000
12,151-12,250...........................          12,200          12,000
------------------------------------------------------------------------

    (ii) You must use the same increment for all equivalent test weight 
classes across your whole product line in a given model year. You must 
also specify curb weight for calculating the work factor in a way that 
is consistent with your approach for determining test weight for 
calculating ADCs under this paragraph (d)(17).
    (e) Useful life. The exhaust emission standards of this section 
apply for the full useful life, as described in Sec.86.1805.
    (f) [Reserved]
    (g) Analytically derived CO2 emission rates (ADCs). This 
paragraph (g) describes an allowance to use estimated (i.e., 
analytically derived) CO2 emission rates based on baseline 
test data instead of measured emission rates for calculating fleet-
average emissions. Note that these ADCs are similar to ADFEs used for 
light-duty vehicles. Note also that F terms used in this paragraph (g) 
represent coefficients from the following road load equation:

Force = F0 + F1 [middot] (velocity) + 
F2 [middot] (velocity)\2\

    (1) Except as specified in paragraph (g)(2) of this section, use the 
following equation to calculate the ADC of a new vehicle from road load 
force coefficients (F0, F1, F2), axle ratio, and test weight:

ADC = CO2base + 2.18 [middot] [Delta]F0 + 37.4 [middot] 
[Delta]F1 + 2257 [middot] [Delta]F2 + 189 [middot] [Delta]AR + 
0.0222[middot] [Delta]ETW

Where:

ADC = Analytically derived combined city/highway CO2 emission 
          rate (g/mile) for a new vehicle.
CO2base = Combined city/highway CO2 emission rate 
          (g/mile) of a baseline vehicle.
[Delta]F0 = F0 of the new vehicle-F0 of the baseline vehicle.
[Delta]F1 = F1 of the new vehicle-F1 of the baseline vehicle.
[Delta]F2 = F2 of the new vehicle-F2 of the baseline vehicle.
[Delta]AR = Axle ratio of the new vehicle-axle ratio of the baseline 
          vehicle.
[Delta]ETW = ETW of the new vehicle-ETW of the baseline vehicle.

    (2) The purpose of this section is to accurately estimate 
CO2 emission rates.
    (i) You must apply the provisions of this section consistent with 
good engineering judgment. For example, do not use the equation in 
paragraph (g)(1) of this section where good engineering judgment 
indicates that it will not accurately estimate emissions. You may ask us 
to approve alternate equations that allow you to estimate emissions more 
accurately.
    (ii) The analytically derived CO2 equation in paragraph 
(g)(1) of this section may be periodically updated through publication 
of an EPA guidance document to more accurately characterize 
CO2 emission levels for example, changes may be appropriate 
based on new test data, future technology changes, or to changes in 
future CO2 emission levels. Any EPA guidance document will 
determine the model year that the updated equation takes effect. We will 
issue guidance no later than eight months before the effective model 
year. For example, model year

[[Page 1011]]

2014 may start January 2, 2013, so guidance for model year 2014 would be 
issued by May 1, 2012.
    (3) You may select baseline test data without our advance approval 
if they meet all the following criteria:
    (i) Vehicles considered for the baseline test must comply with all 
applicable emission standards in the model year associated with the ADC.
    (ii) You must include in the pool of tests considered for baseline 
selection all official tests of the same or equivalent basic engine, 
transmission class, engine code, transmission code, engine horsepower, 
dynamometer drive wheels, and compression ratio as the ADC 
subconfiguration. Do not include tests in which emissions exceed any 
applicable standard.
    (iii) Where necessary to minimize the CO2 adjustment, you 
may supplement the pool with tests associated with worst-case engine or 
transmission codes and carryover or carry-across test groups. If you do, 
all the data that qualify for inclusion using the elected worst-case 
substitution (or carryover or carry-across) must be included in the pool 
as supplemental data (i.e., individual test vehicles may not be selected 
for inclusion). You must also include the supplemental data in all 
subsequent pools, where applicable.
    (iv) Tests previously used during the subject model year as baseline 
tests in ten other ADC subconfigurations must be eliminated from the 
pool.
    (v) Select the tested subconfiguration with the smallest absolute 
difference between the ADC and the test CO2 emission rate for 
combined emissions. Use this as the baseline test for the target ADC 
subconfiguration.
    (4) You may ask us to allow you to use baseline test data not fully 
meeting the provisions of paragraph (g)(3) of this section.
    (5) Calculate the ADC rounded to the nearest whole g/mile. Except 
with our advance approval, the downward adjustment of ADC from the 
baseline is limited to ADC values 20 percent below the baseline emission 
rate. The upward adjustment is not limited.
    (6) You may not submit an ADC if an actual test has been run on the 
target subconfiguration during the certification process or on a 
development vehicle that is eligible to be declared as an emission-data 
vehicle.
    (7) No more than 40 percent of the subconfigurations tested in your 
final CO2 submission may be represented by ADCs.
    (8) Keep the following records for at least five years, and show 
them to us if we ask to see them:
    (i) The pool of tests.
    (ii) The vehicle description and tests chosen as the baseline and 
the basis for the selection.
    (iii) The target ADC subconfiguration.
    (iv) The calculated emission rates.
    (9) We may perform or order a confirmatory test of any 
subconfiguration covered by an ADC.
    (10) Where we determine that you did not fully comply with the 
provisions of this paragraph (g), we may require that you comply based 
on actual test data and that you recalculate your fleet-average emission 
rate.
    (h) Air conditioning leakage. Loss of refrigerant from your air 
conditioning systems may not exceed a total leakage rate of 11.0 grams 
per year or a percent leakage rate of 1.50 percent per year, whichever 
is greater. This applies for all refrigerants. Calculate the total 
leakage rate in g/year as specified in Sec.86.1867-12(a). Calculate 
the percent leakage rate as: [total leakage rate (g/yr)] / [total 
refrigerant capacity (g)] x 100. Round your percent leakage rate to the 
nearest one-hundredth of a percent. For purpose of this requirement, 
``refrigerant capacity'' is the total mass of refrigerant recommended by 
the vehicle manufacturer as representing a full charge. Where full 
charge is specified as a pressure, use good engineering judgment to 
convert the pressure and system volume to a mass.
    (i) [Reserved]
    (j) Optional GHG certification under this subpart. You may certify 
certain complete or cab-complete vehicles to the GHG standards of this 
section. All vehicles optionally certified under this paragraph (j) are 
deemed to be subject to the GHG standards of this section. Note that for 
vehicles above 14,000 pounds GVWR and at or below 26,000 pounds GVWR, 
GHG certification under this paragraph (j) does not affect

[[Page 1012]]

how you may or may not certify with respect to criteria pollutants.
    (1) For GHG compliance, you may certify any complete or cab-complete 
spark-ignition vehicles above 14,000 pounds GVWR and at or below 26,000 
pounds GVWR to the GHG standards of this section even though this 
section otherwise specifies that you may certify vehicles to the GHG 
standards of this section only if they are chassis-certified for 
criteria pollutants.
    (2) You may apply the provisions of this section to cab-complete 
vehicles based on a complete sister vehicle. In unusual circumstances, 
you may ask us to apply these provisions to Class 2b or Class 3 
incomplete vehicles that do not meet the definition of cab-complete.
    (i) Except as specified in paragraph (j)(3) of this section, for 
purposes of this section, a complete sister vehicle is a complete 
vehicle of the same vehicle configuration as the cab-complete vehicle. 
You may not apply the provisions of this paragraph (j) to any vehicle 
configuration that has a four-wheel rear axle if the complete sister 
vehicle has a two-wheel rear axle.
    (ii) Calculate the target value for fleet-average CO2 
emissions under paragraph (a) or (k)(4) of this section based on the 
work factor value that applies for the complete sister vehicle.
    (iii) Test these cab-complete vehicles using the same equivalent 
test weight and other dynamometer settings that apply for the complete 
vehicle from which you used the work factor value (the complete sister 
vehicle). For GHG certification, you may submit the test data from that 
complete sister vehicle instead of performing the test on the cab-
complete vehicle.
    (iv) You are not required to produce the complete sister vehicle for 
sale to use the provisions of this paragraph (j)(2). This means the 
complete sister vehicle may be a carryover vehicle from a prior model 
year or a vehicle created solely for the purpose of testing.
    (3) For GHG purposes, if a cab-complete vehicle is not of the same 
vehicle configuration as a complete sister vehicle due only to certain 
factors unrelated to coastdown performance, you may use the road-load 
coefficients from the complete sister vehicle for certification testing 
of the cab-complete vehicle, but you may not use emission data from the 
complete sister vehicle for certifying the cab-complete vehicle.
    (k) Interim provisions. The following provisions apply instead of 
other provisions in this subpart:
    (1) Incentives for early introduction. Manufacturers may voluntarily 
certify in model year 2013 (or earlier model years for electric 
vehicles) to the greenhouse gas standards that apply starting in model 
year 2014 as specified in 40 CFR 1037.150(a).
    (2) Early credits. To generate early credits under this paragraph 
(k)(2) for any vehicles other than electric vehicles, you must certify 
your entire U.S.-directed fleet to these standards. If you calculate a 
separate fleet average for advanced-technology vehicles under paragraph 
(k)(7) of this section, you must certify your entire U.S.-directed 
production volume of both advanced and conventional vehicles within the 
fleet. If some test groups are certified after the start of the model 
year, you may generate credits only for production that occurs after all 
test groups are certified. For example, if you produce three test groups 
in an averaging set and you receive your certificates for those test 
groups on January 4, 2013, March 15, 2013, and April 24, 2013, you may 
not generate credits for model year 2013 for vehicles from any of the 
test groups produced before April 24, 2013. Calculate credits relative 
to the standard that would apply in model year 2014 using the applicable 
equations in this subpart and your model year 2013 U.S.-directed 
production volumes. These credits may be used to show compliance with 
the standards of this subpart for 2014 and later model years. We 
recommend that you notify us of your intent to use this provision before 
submitting your applications.
    (3) Compliance date. Compliance with the standards of this section 
was optional before January 1, 2014 as specified in 40 CFR 1037.150(g).
    (4) Phase-in provisions. Each manufacturer must choose one of the

    (5) Provisions for small manufacturers. Standards apply on a delayed 
schedule for manufacturers meeting the small business criteria specified 
in 13 CFR 121.201 (NAICS code 336111); the employee and revenue limits 
apply to the total number employees and total revenue together for 
affiliated companies. Qualifying small manufacturers are not subject to 
the greenhouse gas

[[Page 1014]]

standards of this section for vehicles with a date of manufacture before 
January 1, 2022, as specified in 40 CFR 1037.150(c). In addition, small 
manufacturers producing vehicles that run on any fuel other than 
gasoline, E85, or diesel fuel may delay complying with every later 
standard under this part by one model year.
    (6) Alternate N2O standards. Manufacturers may show compliance with 
the N2O standards using an engineering analysis. This 
allowance also applies for model year 2015 and later test groups carried 
over from model 2014 consistent with the provisions of Sec.86.1839. 
You may not certify to an N2O FEL different than the standard 
without measuring N2O emissions.
    (7) Advanced-technology credits. Provisions for advanced-technology 
credits apply as described in 40 CFR 1037.615. If you generate credits 
from Phase 1 vehicles certified with advanced technology, you may 
multiply these credits by 1.50. If you generate credits from Phase 2 
vehicles certified with advanced technology, you may multiply these 
credits by 3.5 for plug-in hybrid electric vehicles, 4.5 for electric 
vehicles, and 5.5 for fuel cell vehicles. Advanced-technology credits 
from Phase 1 vehicles may be used to show compliance with any standards 
of this part or 40 CFR part 1036 or part 1037, subject to the 
restrictions in 40 CFR 1037.740. Similarly, you may use up to 60,000 Mg 
per year of advanced-technology credits generated under 40 CFR 1036.615 
or 1037.615 (from Phase 1 vehicles) to demonstrate compliance with the 
CO2 standards in this section. Include vehicles generating 
credits in separate fleet-average calculations (and exclude them from 
your conventional fleet-average calculation). You must first apply these 
advanced-technology vehicle credits to any deficits for other vehicles 
in the averaging set before applying them to other averaging sets.
    (8) Loose engine sales. This paragraph (k)(8) applies for model year 
2023 and earlier spark-ignition engines with identical hardware compared 
with engines used in vehicles certified to the standards of this 
section, where you sell such engines as loose engines or as engines 
installed in incomplete vehicles that are not cab-complete vehicles. You 
may include such engines in a test group certified to the standards of 
this section, subject to the following provisions:
    (i) Engines certified under this paragraph (k)(8) are deemed to be 
certified to the standards of 40 CFR 1036.108 as specified in 40 CFR 
1036.150(j).
    (ii) For 2020 and earlier model years, the maximum allowable U.S.-
directed production volume of engines you sell under this paragraph 
(k)(8) in any given model year is ten percent of the total U.S-directed 
production volume of engines of that design that you produce for heavy-
duty applications for that model year, including engines you produce for 
complete vehicles, cab-complete vehicles, and other incomplete vehicles. 
The total number of engines you may certify under this paragraph (k)(8), 
of all engine designs, may not exceed 15,000 in any model year. Engines 
produced in excess of either of these limits are not covered by your 
certificate. For example, if you produce 80,000 complete model year 2017 
Class 2b pickup trucks with a certain engine and 10,000 incomplete model 
year 2017 Class 3 vehicles with that same engine, and you do not apply 
the provisions of this paragraph (k)(8) to any other engine designs, you 
may produce up to 10,000 engines of that design for sale as loose 
engines under this paragraph (k)(8). If you produced 11,000 engines of 
that design for sale as loose engines, the last 1,000 of them that you 
produced in that model year 2017 would be considered uncertified.
    (iii) For model years 2021 through 2023, the U.S.-directed 
production volume of engines you sell under this paragraph (k)(8) in any 
given model year may not exceed 10,000 units.
    (iv) This paragraph (k)(8) does not apply for engines certified to 
the standards of 40 CFR 1036.108.
    (v) Label the engines as specified in 40 CFR 1036.135 including the 
following compliance statement: ``THIS ENGINE WAS CERTIFIED TO THE 
ALTERNATE GREENHOUSE GAS EMISSION STANDARDS OF 40 CFR 1036.150(j).'' 
List the test group name instead of an engine family name.
    (vi) Vehicles using engines certified under this paragraph (k)(8) 
are subject

[[Page 1015]]

to the emission standards of 40 CFR 1037.105.
    (vii) For certification purposes, your engines are deemed to have a 
CO2 target value and test result equal to the CO2 
target value and test result for the complete vehicle in the applicable 
test group with the highest equivalent test weight, except as specified 
in paragraph (k)(8)(vii)(B) of this section. Use these values to 
calculate your target value, fleet-average emission rate, and in-use 
emission standard. Where there are multiple complete vehicles with the 
same highest equivalent test weight, select the CO2 target 
value and test result as follows:
    (A) If one or more of the CO2 test results exceed the 
applicable target value, use the CO2 target value and test 
result of the vehicle that exceeds its target value by the greatest 
amount.
    (B) If none of the CO2 test results exceed the applicable 
target value, select the highest target value and set the test result 
equal to it. This means that you may not generate emission credits from 
vehicles certified under this paragraph (k)(8).
    (viii) Production and in-use CO2 standards apply as 
described in paragraph (b) of this section.
    (ix) N2O and CH4 standards apply as described 
in paragraph (c) of this section.
    (x) State in your applications for certification that your test 
group and engine family will include engines certified under this 
paragraph (k)(8). This applies for your greenhouse gas vehicle test 
group and your criteria pollutant engine family. List in each 
application the name of the corresponding test group/engine family.
    (9) Credit adjustment for useful life. For credits that you 
calculate based on a useful life of 120,000 miles, multiply any banked 
credits that you carry forward for use in model year 2021 and later by 
1.25.
    (10) CO2 rounding. For model year 2014 and earlier vehicles, you may 
round measured and calculated CO2 emission levels to the 
nearest 0.1 g/mile, instead of the nearest whole g/mile as specified in 
paragraphs (a), (b), and (g) of this section.

[81 FR 73895, Oct. 25, 2016]



Sec.86.1820-01  Durability group determination.

    This section applies to the grouping of vehicles into durability 
groups. Manufacturers shall divide their product line into durability 
groups based on the following criteria:
    (a) The vehicles covered by a certification application shall be 
divided into groups of vehicles which are expected to have similar 
emission deterioration and emission component durability characteristics 
throughout their useful life. Manufacturers shall use good engineering 
judgment in dividing their vehicles into durability groups. Such groups 
of vehicles are defined as durability groups.
    (b) To be included in the same durability group, vehicles must be 
identical in all the respects listed in paragraphs (b) (1) through (7) 
of this section:
    (1) Combustion cycle (e.g., two stroke, four stroke, Otto cycle, 
diesel cycle).
    (2) Engine type (e.g., piston, rotary, turbine, air cooled versus 
water cooled).
    (3) Fuel used (e.g., gasoline, diesel, methanol, ethanol, CNG, LPG, 
flexible fuels).
    (4) Basic fuel metering system (e.g., throttle body injection, port 
injection (including central port injection), carburetor, CNG mixer 
unit).
    (5) Catalyst construction (for example, beads or monolith).
    (6) Precious metal composition of the catalyst by the type of 
principal active material(s) used (e.g., platinum based oxidation 
catalyst, palladium based oxidation catalyst, platinum and rhodium 
three-way catalyst, palladium and rhodium three way catalyst, platinum 
and palladium and rhodium three way catalyst).
    (7) The manufacturer must choose one of the following two criteria:
    (i) Grouping statistic:
    (A) Vehicles are grouped based upon the value of the grouping 
statistic determined using the following equation:

GS = [(Cat Vol)/(Disp)] x Loading Rate


Where:

GS = Grouping Statistic used to evaluate the range of precious metal 
          loading rates and relative sizing of the catalysts compared

[[Page 1016]]

          to the engine displacement that are allowable within a 
          durability group. The grouping statistic shall be rounded to a 
          tenth of a gram/liter.
Cat Vol = Total volume of the catalyst(s) in liters.
Disp = Displacement of the engine in liters.
Loading rate = The mass of total precious metal(s) in the catalyst (or 
          the total mass of all precious metal(s) of all the catalysts 
          if the vehicle is equipped with multiple catalysts) in grams 
          divided by the total volume of the catalyst(s) in liters.

    (B) Engine-emission control system combinations which have a 
grouping statistic which is either less than 25 percent of the largest 
grouping statistic value, or less than 0.2 g/liter (whichever allows the 
greater coverage of the durability group) shall be grouped into the same 
durability group.
    (ii) The manufacturer may elect to use another procedure which 
results in at least as many durability groups as required using criteria 
in paragraph (b)(7)(i) of this section providing that only vehicles with 
similar emission deterioration or durability are combined into a single 
durability group.
    (c) Where vehicles are of a type which cannot be divided into 
durability groups based on the criteria listed above (such as non-
catalyst control system approaches), the Administrator will establish 
durability groups for those vehicles based upon the features most 
related to their exhaust emission deterioration characteristics.
    (d) Manufacturers may further divide groups determined under 
paragraph (b) of this section provided the Administrator is notified of 
any such changes prior to or concurrently with the submission of the 
application for certification (preferably at an annual preview meeting 
scheduled before the manufacturer begins certification activities for 
the model year).
    (e) Manufacturers may request the Administrator's approval to 
combine vehicles into a single durability group which would normally not 
be eligible to be in a single durability group. The petition should 
provide:
    (1) Substantial evidence that all the vehicles in the larger 
grouping will have the same degree of emission deterioration;
    (2) Evidence of equivalent component durability over the vehicle's 
useful life; and
    (3) Evidence that the groups will result in sufficient In-Use 
Verification Program data, appropriate tracking in use, and clear 
liability for the Agency's recall program.

[64 FR 23925, May 4, 1999, as amended at 81 FR 73991, Oct. 25, 2016]



Sec.86.1821-01  Evaporative/refueling family determination.

    (a) The gasoline-, ethanol-, methanol-, liquefied petroleum gas-, 
and natural gas-fueled vehicles described in a certification application 
will be divided into groupings expected to have similar evaporative and/
or refueling emission characteristics (as applicable) throughout their 
useful life. Each group of vehicles with similar evaporative and/or 
refueling emission characteristics shall be defined as a separate 
evaporative/refueling family. Manufacturers shall use good engineering 
judgment to determine evaporative/refueling families.
    (b) For vehicles that operate on volatile liquid fuels to be classed 
in the same evaporative/refueling family, they must be similar with 
respect to all the following items:
    (1) Type of vapor storage device (e.g., canister, air cleaner, 
crankcase).
    (2) Basic canister design.
    (i) Working capacity--grams adsorption within a 10 g. range.
    (ii) System configuration--number of canisters and method of 
connection (i.e., series, parallel).
    (iii) Canister geometry, construction and materials.
    (3) Fuel system.
    (4) Type of refueling emission control system--non-integrated or 
integrated with the evaporative control system. Further, if the system 
is non-integrated, whether or not any other evaporative emissions, e.g. 
diurnal or hot soak emissions, are captured in the same storage device 
as the refueling emissions.
    (5) Fillpipe seal mechanism--mechanical, liquid trap, other.
    (6) Vapor control system or method of controlling vapor flow through 
the vapor line to the canister (for example, type of valve, vapor 
control strategy).

[[Page 1017]]

    (7) Purge control system (for example, type of valve, purge control 
strategy).
    (8) Vapor hose material.
    (9) Fuel tank material.
    (10) Evaporative emission standard or family emission limit (FEL).
    (c) Where vehicles are of a type which cannot be divided into 
evaporative/refueling families based on the criteria listed above (such 
as non-canister control system approaches), the Administrator will 
establish families for those vehicles based upon the features most 
related to their evaporative and/or refueling emission characteristics.
    (d) Manufacturers may further divide families determined under 
paragraph (b) of this section provided the Administrator is notified of 
any such changes prior to or concurrently with the submission of the 
application for certification (preferably at an annual preview meeting 
scheduled before the manufacturer begins certification activities for 
the model year).
    (e) Manufacturers may petition the Administrator to combine vehicles 
into a single evaporative/refueling family which would normally not be 
eligible to be in a single evaporative/refueling family. The petition 
should provide:
    (1) Substantial evidence that all the vehicles in the larger 
grouping will have the same degree of evaporative emission 
deterioration;
    (2) Evidence of equivalent component durability over the vehicle's 
useful life; and
    (3) Evidence that the groups will result in sufficient In-Use 
Verification Program data, appropriate tracking in use, and clear 
liability for the Agency's recall program.
    (f) For vehicles to be classed in the same leak family, they must be 
similar with respect to the items listed in paragraph (b) of this 
section and use the same OBD method for detecting leaks.

[64 FR 23925, May 4, 1999, as amended at 79 FR 23725, Apr. 28, 2014



Sec.86.1822-01  Durability data vehicle selection.

    (a) Within each durability group, the vehicle configuration which is 
expected to generate the highest level of exhaust emission deterioration 
on candidate vehicles in use, considering all constituents, shall be 
selected as the durability data vehicle configuration. The manufacturer 
will use good engineering judgment in making this selection.
    (b) The manufacturer may select, using good engineering judgment, an 
equivalent or worst-case configuration in lieu of testing the vehicle 
selected in paragraph (a) of this section. Carryover data satisfying the 
provisions of Sec.86.1839-01 may also be used in lieu of testing the 
configuration selected in paragraph (a) of this section.



Sec.86.1823-01  Durability demonstration procedures for exhaust
emissions.

    This section applies to light-duty vehicles, light-duty trucks, 
complete heavy-duty vehicles, and heavy-duty vehicles certified under 
the provisions of Sec.86.1801-01(c). Eligible small volume 
manufacturers or small volume test groups may optionally meet the 
requirements of Sec. Sec.86.1838-01 and 86.1826-01 in lieu of the 
requirements of this section. For model years 2001, 2002, and 2003 all 
manufacturers may elect to meet the provisions of paragraph (c)(2) of 
this section in lieu of these requirements for light-duty vehicles or 
light-duty trucks.
    (a) The manufacturer shall propose a durability program consisting 
of the elements discussed in paragraphs (a)(1) through (a)(3) of this 
section for advance approval by the Administrator. The durability 
process shall be designed to effectively predict the expected 
deterioration of candidate in-use vehicles over their full and 
intermediate useful life and shall be consistent with good engineering 
judgment. The Administrator will approve the program if he/she 
determines that it is reasonably expected to meet these design 
requirements.
    (1) Service accumulation method. (i) Each durability program shall 
include a service accumulation method designed to effectively predict 
the deterioration of emissions in actual use over the full and 
intermediate useful life of candidate in-use vehicles.
    (ii) Manufacturers may propose service accumulation methods based 
upon whole-vehicle full-mileage accumulation, whole vehicle accelerated 
mileage

[[Page 1018]]

accumulation (e.g., where 40,000 miles on a severe mileage accumulation 
cycle is equivalent to 100,000 miles of normal in-use driving), bench 
aging of individual components or systems, or other approaches approved 
by the Administrator.
    (A) For whole vehicle mileage accumulation programs, all emission 
control components and systems (including both hardware and software) 
must be installed and operating for the entire mileage accumulation 
period.
    (B) Bench procedures shall simulate the aging of components or 
systems over the applicable useful life and shall simulate driving 
patterns and vehicle operational environments found in actual use. For 
this purpose, manufacturers may remove the emission-related components 
(and other components), in whole or in part, from the durability vehicle 
itself and deteriorate them independently. Vehicle testing for the 
purpose of determining deterioration factors may include the testing of 
durability vehicles that incorporate such bench-aged components.
    (2) Vehicle/component selection method. The manufacturer shall 
propose a vehicle/component selection method for advance approval by the 
Administrator. The procedure for selecting durability data vehicles and 
components shall meet the requirements of Sec.86.1822-01.
    (3) Use of deterioration program to determine compliance with the 
standard. The manufacturer shall propose procedures for the 
determination of compliance with the standards for advance approval by 
the Administrator. The calculation of deterioration factors and/or the 
determination of vehicle compliance shall be according to the procedures 
approved in advance by the Administrator. The Administrator will allow 
two methods for using the results of the deterioration program to 
determine compliance with the standards. Either a deterioration factor 
(DF) is calculated and applied to the emission data vehicle (EDV) 
emission results or aged components are installed on the EDV prior to 
emission testing. Other methods may be approved by the Administrator if 
they result in an effective prediction of intermediate and full useful 
life emission levels on candidate in-use vehicles.
    (i) Use of deterioration factors. (A) Deterioration factors are 
calculated using all FTP emission test data generated during the 
durability testing program except as noted:
    (1) Multiple tests at a given mileage point are averaged together 
unless the same number of tests are conducted at each mileage point.
    (2) Before and after maintenance test results are averaged together.
    (3) Zero-mile test results are excluded from the calculation.
    (4) When calculating intermediate and full useful life deterioration 
factors all data points should be included in the calculations, except 
that total hydrocarbon (THC) test points beyond the 50,000-mile (useful 
life) test point shall not be included in the calculations.
    (5) A procedure may be employed to identify and remove from the DF 
calculation those test results determined to be statistical outliers 
providing that the outlier procedure is consistently applied to all 
vehicles and data points and is approved in advance by the 
Administrator.
    (B) The deterioration factor shall be based on a linear regression, 
or an other regression technique approved in advance by the 
Administrator. The deterioration may be a multiplicative or additive 
factor. Separate factors will be calculated for each regulated emission 
constituent and for the full and intermediate useful life periods as 
applicable. Separate DF's are calculated for each durability group 
except as provided in paragraph (c) of this section.
    (1) A multiplicative DF will be calculated by taking the ratio of 
the full or intermediate useful life mileage level, as appropriate 
(rounded to four decimal places), divided by the stabilized mileage 
(reference Sec.86.1831-01(c), e.g., 4000-mile) level (rounded to four 
decimal places) from the regression analysis; the result shall be 
rounded to three-decimal places of accuracy. The rounding required in 
this paragraph shall be conducted in accordance with the Rounding-Off 
Method specified in ASTM E29-93a, Standard Practice for Using 
Significant Digits in Test Data to Determine Conformance with 
Specifications (incorporated by

[[Page 1019]]

reference, see Sec.86.1). Calculated DF values of less than one shall 
be changed to one for the purposes of this paragraph.
    (2) An additive DF will be calculated to be the difference between 
the full or intermediate useful life mileage level (as appropriate) 
minus the stabilized mileage (reference Sec.86.1831-01(c), e.g. 4000-
mile) level from the regression analysis. The full useful life regressed 
emission value, the stabilized mileage regressed emission value, and the 
DF result shall be rounded to the same precision and using the same 
procedures as the raw emission results according to the provisions of 
Sec.86.1837-01. Calculated DF values of less than zero shall be 
changed to zero for the purposes of this paragraph.
    (C) The DF calculated by these procedures will be used for 
determining compliance with FTP exhaust emission standards, SFTP exhaust 
emission standards, cold temperature NMHC emission standards, and cold 
temperature CO emission standards. At the manufacturer's option and 
using procedures approved by the Administrator, a separate DF may be 
calculated exclusively using cold temperature CO test data to determine 
compliance with cold temperature CO emission standards. Similarly, at 
the manufacturer's option and using procedures approved by the 
Administrator, a separate DF may be calculated exclusively using cold 
temperature NMHC test data to determine compliance with cold temperature 
NMHC emission standards. For determining compliance with full useful 
life cold temperature NMHC emission standards, the 68-86 [deg]F 120,000 
mile full useful life NMOG DF may be used. Also at the manufacturer's 
option and using procedures approved by the Administrator, a separate DF 
may be calculated exclusively using US06 and/or air conditioning (SC03) 
test data to determine compliance with the SFTP emission standards.
    (ii) Installation of aged components on emission data vehicles. For 
full and intermediate useful life compliance determination, the 
manufacturer may elect to install aged components on an EDV rather than 
applying a deterioration factor. Different sets of components may be 
aged for full and intermediate useful life periods. The list of 
components to be installed, the techniques used to select physical parts 
to be aged, and the aging techniques employed to age the components must 
be approved in advance by the Administrator.
    (b) In addition to the provisions of paragraph (a) of this section, 
manufacturers shall submit the following information when applying for 
the Administrator's approval of a durability program:
    (1) Analysis and/or data demonstrating the adequacy of the 
manufacturer's durability processes to effectively predict emission 
compliance for candidate in-use vehicles. All regulated emission 
constituents and all test procedures shall be considered in this 
analysis. This data and discussion shall cover the breadth of the 
manufacturer's product line that will be covered by this durability 
procedure.
    (2) Discussion of the manufacturer's in-use verification procedures 
including testing performed, vehicle procurement procedures used, and 
vehicles rejection criteria used. Any questionnaires used or inspections 
performed should also be documented in the manufacturer's submission. 
The in-use verification program shall meet the requirements of 
Sec. Sec.86.1845-01, 86.1846-01 and 86.1847-01.
    (c) Carryover and carryacross. (1) Manufacturers may carry over or 
carry across mileage accumulation data, aged hardware, or deterioration 
factors according to the provisions of Sec.86.1839-01 using good 
engineering judgment.
    (2) For the 2001, 2002, and 2003 model years, for light-duty 
vehicles and light-duty trucks the manufacturer may carry over exhaust 
emission DF's previously generated under the Standard AMA Durability 
Program described in Sec.86.094-13(c), the Alternate Service 
Accumulation Durability Program described in Sec.86.094-13(e) or the 
Standard Self-Approval Durability Program for light-duty trucks 
described in Sec.86.094-13(f) in lieu of complying with the durability 
provisions of paragraph (a)(1) of this section.
    (i) This provision is limited to the use of existing data used for a 
2000 model year or earlier certification. All new exhaust durability 
data must be

[[Page 1020]]

generated according to the provisions of paragraph (a)(1) of this 
section.
    (ii) The manufacturer shall exercise good engineering judgment when 
determining the eligibility to use carryover exhaust emission DF's and 
the selection of the vehicle used as the source of carryover.
    (iii) Starting with the 2004 model year, manufacturers must meet the 
provisions of paragraphs (a) and (b) of this section.
    (d) Data reporting requirements. Data reporting requirements are 
contained in Sec.86.1844-01.
    (e) Emission component durability. The manufacturer shall use good 
engineering judgment to determine that all emission-related components 
are designed to operate properly for the full useful life of the 
vehicles in actual use.
    (f) In-use verification. The durability program must meet the 
requirements of Sec.86.1845-01.
    (g) The manufacturer shall apply the approved durability process to 
a durability group, including durability groups in future model years, 
if the durability process will effectively predict (or alternatively, 
overstate) the deterioration of emissions in actual use over the full 
and intermediate useful life of candidate in-use vehicles. The 
manufacturer shall use good engineering judgment in determining the 
applicability of the durability program to a durability group.
    (1) The manufacturer may make modifications to an approved 
durability process using good engineering judgment for the purpose of 
ensuring that the modified process will effectively predict, (or 
alternatively, overstate) the deterioration of emissions in actual use 
over the full and intermediate useful life of candidate in-use vehicles.
    (2) The manufacturer shall notify the Administrator of its 
determination to use an approved (or modified) durability program on 
particular test groups and durability groups prior to emission data 
vehicle testing for the affected test groups (preferably at an annual 
preview meeting scheduled before the manufacturer begins certification 
activities for the model year).
    (3) Prior to certification, the Administrator may reject the 
manufacturer's determination in paragraph (g) of this section if it is 
not made using good engineering judgment or it fails to properly 
consider data collected under the provisions of Sec. Sec.86.1845-01, 
86.1846-01, and 86.1847-01 or other information if the Administrator 
determines that the durability process has not been shown to effectively 
predict emission levels or compliance with the standards in use on 
candidate vehicles for particular test groups which the manufacturers 
plan to cover with the durability process.
    (h) The Administrator may withdraw approval to use a durability 
process or require modifications to a durability process based on the 
data collected under Sec. Sec.86.1845-01, 86.1846-01, and 86.1847-01 
or other information if the Administrator determines that the durability 
processes have not been shown to accurately predict emission levels or 
compliance with the standards (or FEL, as applicable) in use on 
candidate vehicles (provided the inaccuracy could result in a lack of 
compliance with the standards for a test group covered by this 
durability process). Such withdrawals shall apply to future applications 
for certification and to the portion of the manufacturer's product line 
(or the entire product line) that the Administrator determines to be 
affected. Prior to such a withdrawal the Administrator shall give the 
manufacturer a preliminary notice at least 60 days prior to the final 
decision. During this period, the manufacturer may submit technical 
discussion, statistical analyses, additional data, or other information 
which is relevant to the decision. The Administrator will consider all 
information submitted by the deadline before reaching a final decision.
    (i) Any manufacturer may request a hearing on the Administrator's 
withdrawal of approval in paragraph (h) of this section. The request 
shall be in writing and shall include a statement specifying the 
manufacturer's objections to the Administrator's determinations, and 
data in support of such objection. If, after review of the request and 
supporting data, the Administrator finds that the request raises a 
substantial factual issue, she/he shall provide the manufacturer a 
hearing in

[[Page 1021]]

accordance with Sec.86.1853-01 with respect to such issue.

Sec.86.1823-08  Durability demonstration procedures for exhaust
emissions.

    This section describes durability demonstration procedures for 
exhaust emissions. Eligible small-volume manufacturers or small-volume 
test groups may optionally meet the requirements of Sec. Sec.86.1826 
and 86.1838 instead of the requirements of paragraphs (a) through (m) of 
this section. A separate durability demonstration is required for each 
durability group.
    (a) Durability program objective. The durability program must 
predict an expected in-use emission deterioration rate and emission 
level that effectively represents a significant majority of the 
distribution of emission levels and deterioration in actual use over the 
full and intermediate useful life of candidate in-use vehicles of each 
vehicle design which uses the durability program.
    (b) Required durability demonstration. Manufacturers must conduct a 
durability demonstration for each durability group using a procedure 
specified in either paragraph (c), (d), or (e) of this section.
    (c) Standard whole-vehicle durability procedure. This procedure 
consists of conducting mileage accumulation and periodic testing on the 
durability data vehicle, selected under the provisions of Sec.86.1822 
described as follows:
    (1) Mileage accumulation must be conducted using the standard road 
cycle (SRC). The SRC is described in appendix V of this part.
    (i) Mileage accumulation on the SRC may be conducted on a track or 
on a chassis mileage accumulation dynamometer. Alternatively, the entire 
engine and emission control system may be aged on an engine dynamometer 
using methods that will replicate the aging that occurs on the road for 
that vehicle following the SRC.
    (ii) The fuel used for mileage accumulation must comply with the 
mileage accumulation fuel provisions of Sec.86.113 for the applicable 
fuel type (e.g., gasoline or diesel fuel).
    (iii) The DDV must be ballasted to a minimum of the loaded vehicle 
weight for light-duty vehicles and light light-duty trucks and a minimum 
of the ALVW for all other vehicles.
    (iv) The mileage accumulation dynamometer must be setup as follows:
    (A) The simulated test weight will be the equivalent test weight 
specified in Sec.86.129 using a weight basis of the loaded vehicle 
weight for light-duty vehicles and ALVW for all other vehicles.
    (B) The road force simulation will be determined according to the 
provisions of Sec.86.129.
    (C) The manufacturer will control the vehicle, engine, and/or 
dynamometer as appropriate to follow the SRC using good engineering 
judgement.
    (2) Mileage accumulation must be conducted for at least 75% of the 
applicable full useful life mileage period specified in Sec.86.1805. 
If the mileage accumulation is less than 100% of the full useful life 
mileage, then the DF calculated according to the procedures of paragraph 
(f)(1)(ii) of this section must be based upon a line projected to the 
full-useful life mileage using the upper 80 percent statistical 
confidence limit calculated from the emission data.
    (3) If a manufacturer elects to calculate a DF pursuant to paragraph 
(f)(1) of this section, then it must conduct at least one FTP emission 
test at each of five different mileage points selected using good 
engineering judgement. Additional testing may be conducted by the 
manufacturer using good engineering judgement. The required testing must 
include testing at 5,000 miles and at the highest mileage point run 
during mileage accumulation (e.g. the full useful life mileage). 
Different testing plans may be used providing that the manufacturer 
determines, using good engineering judgement, that the alternative plan 
would result in an equivalent or superior level of confidence in the 
accuracy of the DF calculation compared to the testing plan specified in 
this paragraph.
    (d) Standard bench-aging durability procedure. This procedure is not 
applicable to diesel fueled vehicles or vehicles which do not use a 
catalyst as the principle after-treatment emission control device. This 
procedure requires installation of the catalyst-plus-oxygen-

[[Page 1022]]

sensor system on a catalyst aging bench. Aging on the bench is conducted 
by following the standard bench cycle (SBC) for the period of time 
calculated from the bench aging time (BAT) equation. The BAT equation 
requires, as input, catalyst time-at-temperature data measured on the 
SRC.
    (1) Standard bench cycle (SBC). Standard catalyst bench aging is 
conducted following the SBC
    (i) The SBC must be run for the period of time calculated from the 
BAT equation.
    (ii) The SBC is described in appendix VII to part 86.
    (2) Catalyst time-at-temperature data (i) Catalyst temperature must 
be measured during at least two full cycles of the SRC.
    (ii) Catalyst temperature must be measured at the highest 
temperature location in the hottest catalyst on the DDV. Alternatively, 
the temperature may be measured at another location providing that it is 
adjusted to represent the temperature measured at the hottest location 
using good engineering judgement.
    (iii) Catalyst temperature must be measured at a minimum rate of one 
hertz (one measurement per second).
    (iv) The measured catalyst temperature results must be tabulated 
into a histogram with temperature bins of no larger than 25 [deg]C.
    (3) Bench-aging time. Bench aging time is calculated using the bench 
aging time (BAT) equation as follows:

te for a temperature bin = th 
e((R/Tr)-(R/Tv))
Total te = Sum of te over all the temperature bins
Bench-Aging Time = A (Total te)


Where:

A = 1.1 This value adjusts the catalyst aging time to account for 
deterioration from sources other than thermal aging of the catalyst.
R = Catalyst thermal reactivity coefficient. You may use a default value 
of 17,500 for the SBC.
th = The time (in hours) measured within the prescribed 
temperature bin of the vehicle's catalyst temperature histogram adjusted 
to a full useful life basis e.g., if the histogram represented 400 
miles, and full useful life was 100,000 miles; all histogram time 
entries would be multiplied by 250 (100000/400).
Total te = The equivalent time (in hours) to age the catalyst 
at the temperature of Tr on the catalyst aging bench using 
the catalyst aging cycle to produce the same amount of deterioration 
experienced by the catalyst due to thermal deactivation over the 
vehicle's full useful life.
te for a bin = The equivalent time (in hours) to age the 
catalyst at the temperature of Tr on the catalyst aging bench 
using the catalyst aging cycle to produce the same amount of 
deterioration experienced by the catalyst due to thermal deactivation at 
the temperature bin of Tv over the vehicle's full useful 
life.
Tr = The effective reference temperature (in [deg]K) of the 
catalyst on the catalyst bench run on the bench aging cycle. The 
effective temperature is the constant temperature that would result in 
the same amount of aging as the various temperatures experienced during 
the bench aging cycle.
Tv = The mid-point temperature (in [deg]K) of the temperature 
bin of the vehicle on-road catalyst temperature histogram.

    (4) Effective reference temperature on the SBC. The effective 
reference temperature of the standard bench cycle (SBC) is determined 
for the actual catalyst system design and actual aging bench which will 
be used using the following procedures:
    (i) Measure time-at-temperature data in the catalyst system on the 
catalyst aging bench following the SBC.
    (A) Catalyst temperature must be measured at the highest temperature 
location of the hottest catalyst in the system. Alternatively, the 
temperature may be measured at another location providing that it is 
adjusted to represent the temperature measured at the hottest location 
using good engineering judgement.
    (B) Catalyst temperature must be measured at a minimum rate of one 
hertz (one measurement per second) during at least 20 minutes of bench 
aging.

[[Page 1023]]

    (C) The measured catalyst temperature results must be tabulated into 
a histogram with temperature bins of no larger than 10 [deg]C.
    (ii) The BAT equation must be used to calculate the effective 
reference temperature by iterative changes to the reference temperature 
(Tr) until the calculated aging time equals the actual time 
represented in the catalyst temperature histogram. The resulting 
temperature is the effective reference temperature on the SBC for that 
catalyst system and aging bench.
    (5) Catalyst Aging Bench. The manufacturer must design, using good 
engineering judgement, a catalyst aging bench that follows the SBC and 
delivers the appropriate exhaust flow, exhaust constituents, and exhaust 
temperature to the face of the catalyst.
    (i) A manufacturer may use the criteria and equipment discussed in 
appendix VIII to part 86 to develop its catalyst aging bench without 
prior Agency approval. The manufacturer may use another design that 
results in equivalent or superior results with advance Agency approval.
    (ii) All bench aging equipment and procedures must record 
appropriate information (such as measured A/F ratios and time-at-
temperature in the catalyst) to assure that sufficient aging has 
actually occurred.
    (6) Required Testing. If a manufacturer is electing to calculate a 
DF (as discussed in paragraph (f)(1) of this section), then it must 
conduct at least two FTP emissions tests on the DDV before bench aging 
of emission control hardware and at least two FTP emission tests on the 
DDV after the bench-aged emission hardware is re-installed. Additional 
testing may be conducted by the manufacturer using good engineering 
judgement.
    (e) Additional durability procedures--(1) Whole vehicle durability 
procedures. A manufacturer may use either a customized SRC or an 
alternative road cycle for the required durability demonstration, with 
prior EPA approval.
    (i) Customized SRC. A customized SRC is the SRC run for a different 
number of miles and/or using a different mileage accumulation fuel with 
higher levels of certain compounds that may lead to catalyst poisoning, 
such as phosphorus, sulfur and lead, than specified in paragraph 
(c)(1)(ii) of this section.
    (ii) Alternative road cycle. An alternative cycle is a whole vehicle 
mileage accumulation cycle that uses a different speed-versus-time trace 
than the SRC, conducted for either the full useful life mileage or for 
less than full useful life mileage. An alternative road cycle may also 
include the use of fuel with higher levels of certain compounds that may 
lead to catalyst poisoning, such as phosphorus, sulfur and lead, than 
specified in paragraph (c)(1)(ii) of this section.
    (iii) Approval criteria. The manufacturer must obtain approval from 
EPA prior to using a customized/alternative road cycle. EPA may approve 
a customized/alternative cycle when the manufacturer demonstrates that 
the cycle is expected to achieve the durability program objective of 
paragraph (a) of this section for the breadth of vehicles using the 
customized/alternative cycle. To obtain approval the manufacturer must 
submit all the following information and perform all the following 
analyses:
    (A) The manufacturer must supply in-use FTP emission data on past 
model year vehicles which are applicable to the vehicle designs it 
intends to cover with the customized/alternative cycle.
    (1) The amount of in-use emission data required to demonstrate the 
effectiveness of a customized/alternative cycle in meeting the 
durability objective is based on whether the customized/alternative 
cycle is more or less severe than the SRC. In most cases, EPA will 
accept a minimum of 20 candidate in-use vehicles tested as-received on 
the FTP cycle. If the customized/alternative cycle is significantly more 
severe than the SRC, EPA may accept less data. Conversely, if the 
customized/alternative cycle is significantly less severe than the SRC, 
EPA may require more data, up to a maximum of 30 vehicles.
    (2) This data set must consist of randomly procured vehicles from 
actual customer use. The vehicles selected for procurement must cover 
the breadth of the vehicles that the manufacturer intends to certify 
using the customized/alternative cycle. Vehicles should be

[[Page 1024]]

procured and FTP tested in as-received condition under the guidelines of 
the high mileage IUVP program (ref: 40 CFR 86.1845-04).
    (3) Manufacturers may use previously generated in-use data from the 
CAP 2000 IUVP or the RDP ``reality check'' in-use program as well as 
other sources of in-use emissions data for approval under this section.
    (4) Manufacturers must remove unrepresentative data from the data 
set using good engineering judgement. The manufacturer must provide EPA 
with the data removed from the analysis and a justification for the 
removal of that data.
    (5) Manufacturers may supply additional in-use data.
    (B) The manufacturer must submit an analysis which includes a 
comparison of the relative stringency of the customized/alternative 
cycle to the SRC and a calculated equivalency factor for the cycle.
    (1) The equivalency factor may be determined by an evaluation of the 
SRC and the customized/alternative cycle using catalyst time-at-
temperature data from both cycles with the BAT equation to calculate the 
required bench aging time of each cycle. Once the bench aging time is 
calculated for each cycle, the equivalency factor is the ratio described 
by dividing the bench aging time on the customized/alternative cycle by 
the bench aging time on the SRC.
    (2) If emissions data is available from the SRC, as well as time-at-
temperature data, then that emissions information may be included in the 
evaluation of the relative stringency of the two cycles and the 
development of the equivalency factor.
    (3) A separate equivalency factor may be determined for each test 
group, or test groups may be combined together (using good engineering 
judgement) to calculate a single equivalency factor.
    (C) The manufacturer must submit an analysis which evaluates whether 
the durability objective will be achieved for the vehicle designs which 
will be certified using the customized/alternative cycle. The analysis 
must address of the following elements:
    (1) How the durability objective has been achieved using the data 
submitted in paragraph (e)(1)(iii)(A) of this section.
    (2) How the durability objective will be achieved for the vehicle 
designs which will be covered by the customized/alternative cycle. This 
analysis should consider the emissions deterioration impact of the 
design differences between the vehicles included in the data set 
required in (e)(1)(iii)(A) of this section and the vehicle designs that 
the manufacturer intends to certify using the customized/alternative 
cycle.
    (2) Bench-aging durability procedures. A manufacturer may use a 
customized or alternative bench aging durability procedure for a 
required durability demonstration, if approved as described in 
paragraphs (e)(2)(i) through (vii) of this section. A customized/
alternative bench aging procedure must use vehicle performance data 
(such as catalyst temperature) measured on an approved road cycle as 
part of the algorithm to calculate bench aging time. The manufacturer 
must obtain approval from the Agency prior to using a customized bench 
durability procedure.
    (i) The lower control temperature on the SBC may be modified without 
prior EPA approval provided that the high control temperature is set 90 
[deg]C above the lower control temperature and an approved BAT equation 
is used to calculate bench aging time.
    (ii) The R-factor used in EPA's BAT equation may be determined 
experimentally using EPA's standard procedures (specified in appendix IX 
of this part) without prior EPA approval. Other experimental techniques 
to calculate the R-factor require advance EPA approval. To obtain 
approval, the manufacturer must demonstrate that the calculated bench 
aging time results in the same (or larger) amount of emission 
deterioration as the associated road cycle.
    (iii) The A-factor used in EPA's BAT equation may be modified, using 
good engineering judgement without prior EPA approval, to ensure that 
the modified durability process will achieve the durability objective of 
paragraph (a) of this section.

[[Page 1025]]

    (iv) Bench aging may be conducted using fuel with additional 
compounds that may lead to catalyst poisoning, such as phosphorus, 
sulfur or lead, without prior EPA approval. A manufacturer using fuel 
with these additional compounds may either calculate a new R-factor or 
A-factor to assure that the durability objective of paragraph (a) of 
this section is properly achieved regardless of the use of worst-case 
fuel, in which case the approval criteria for those changes would apply.
    (v) An approved customized/alternative road cycle may be used to 
develop catalyst temperature histograms for use in the BAT equation 
without additional EPA approval beyond the original approval necessary 
to use that cycle for mileage accumulation.
    (vi) A different bench cycle than the SBC may be used during bench 
aging with prior EPA approval. To obtain approval the manufacturer must 
demonstrate that bench aging for the appropriate time on the new bench 
cycle provides the same or larger amount of emission deterioration as 
the associated road cycle.
    (vii) A different method to calculate bench aging time may be used 
with prior EPA approval. To obtain approval the manufacturer must 
demonstrate that bench aging for the time calculated by the alternative 
method results in the same or larger amount of emission deterioration as 
the associated road cycle.
    (f) Use of deterioration program to determine compliance with the 
standard. A manufacturer may select from two methods for using the 
results of the deterioration program to determine compliance with the 
applicable emission standards. Either a deterioration factor (DF) is 
calculated and applied to the emission data vehicle (EDV) emission 
results or aged components are installed on the EDV prior to emission 
testing.
    (1) Deterioration factors. (i) Deterioration factors are calculated 
using all FTP emission test data generated during the durability testing 
program except as noted:
    (A) Multiple tests at a given mileage point are averaged together 
unless the same number of tests are conducted at each mileage point.
    (B) Before and after maintenance test results are averaged together.
    (C) Zero-mile test results are excluded from the calculation.
    (D) Total hydrocarbon (THC) test points beyond the 50,000-mile 
(useful life) test point are excluded from the intermediate useful life 
deterioration factor calculation.
    (E) A procedure may be employed to identify and remove from the DF 
calculation those test results determined to be statistical outliers 
providing that the outlier procedure is consistently applied to all 
vehicles and data points and is approved in advance by the 
Administrator.
    (ii) The deterioration factor must be based on a linear regression, 
or another regression technique approved in advance by the 
Administrator. The deterioration must be a multiplicative or additive 
factor. Separate factors will be calculated for each regulated emission 
constituent and for the full and intermediate useful life periods as 
applicable. Separate DF's are calculated for each durability group 
except as provided in Sec.86.1839.
    (A) A multiplicative DF will be calculated by taking the ratio of 
the full or intermediate useful life mileage level, as appropriate 
(rounded to four decimal places), divided by the stabilized mileage 
(reference Sec.86.1831-01(c), e.g., 4000-mile) level (rounded to four 
decimal places) from the regression analysis. The result must be rounded 
to three-decimal places of accuracy. The rounding required in this 
paragraph must be conducted in accordance with Sec.86.1837. Calculated 
DF values of less than one must be changed to one for the purposes of 
this paragraph.
    (B) An additive DF will be calculated to be the difference between 
the full or intermediate useful life mileage level (as appropriate) 
minus the stabilized mileage (reference Sec.86.1831-01(c), e.g. 4000-
mile) level from the regression analysis. The full useful life regressed 
emission value, the stabilized mileage regressed emission value, and the 
DF result must be rounded to the same precision and using the same 
procedures as the raw emission results according to the provisions of 
Sec.86.1837-01. Calculated DF values of less than zero

[[Page 1026]]

must be changed to zero for the purposes of this paragraph.
    (iii) The DF calculated by these procedures will be used for 
determining full and intermediate useful life compliance with FTP 
exhaust emission standards, SFTP exhaust emission standards, and cold CO 
emission standards. At the manufacturer's option and using procedures 
approved by the Administrator, a separate DF may be calculated 
exclusively using cold CO test data to determine compliance with cold CO 
emission standards. Also at the manufacturer's option and using 
procedures approved by the Administrator, a separate DF may be 
calculated exclusively using US06 and/or air conditioning (SC03) test 
data to determine compliance with the SFTP emission standards.
    (2) Installation of aged components on emission data vehicles. For 
full and intermediate useful life compliance determination, the 
manufacturer may elect to install aged components on an EDV prior to 
emission testing rather than applying a deterioration factor. Different 
sets of components may be aged for full and intermediate useful life 
periods. Components must be aged using an approved durability procedure 
that complies with paragraph (b) of this section. The list of components 
to be aged and subsequently installed on the EDV must selected using 
good engineering judgement.
    (g) [Reserved]
    (h) Application of the durability procedure to future durability 
groups. The manufacturer may apply a durability procedure approved under 
paragraphs (c), (d) or (e) of this section to a durability group, 
including durability groups in future model years, if the durability 
process will achieve the objective of paragraph (a) of this section for 
that durability group. The manufacturer must use good engineering 
judgment in determining the applicability of an approved durability 
procedure to a durability group.
    (1) Modifications to a durability procedure. (i) Standard durability 
procedures. The manufacturer may modify a standard durability procedure 
(allowed in paragraphs (c) or (d) of this section) by increasing or 
decreasing the number of miles run on the SRC to represent full or 
intermediate useful life emissions deterioration or by changing the A-
Factor in the BAT equation for a bench aging, using good engineering 
judgment, to ensure that the modified procedure will achieve the 
objective of paragraph (a) of this section for that durability group.
    (ii) Customized/Alternative durability procedures. The manufacturer 
may modify an alternative/customized durability procedure approved under 
the provisions of paragraph (e) of this section, using good engineering 
judgment, for the purposes of ensuring that the modified procedure will 
achieve the objective of paragraph (a) of this section for that 
durability group.
    (2) The manufacturer must notify the Administrator of its 
determination to use an approved (or modified) durability procedure on 
particular test groups and durability groups prior to, or concurrently 
with, its submission of the Application for Certification for the 
affected test groups (notification at an annual preview meeting 
scheduled before the manufacturer begins certification activities for 
the model year is preferred).
    (3) Prior to certification, the Administrator may reject the 
manufacturer's determination in paragraph (h) of this section to apply 
an approved or modified durability procedure for a durability group or 
test group if:
    (i) It is not made using good engineering judgment,
    (ii) It fails to properly consider data collected under the 
provisions of Sec. Sec.86.1845-04, 86.1846-01, and 86.1847-01 or other 
information, or
    (iii) The Administrator determines that the durability procedure has 
not been shown to achieve the objective of paragraph (a) of this section 
for particular test groups which the manufacturer plans to cover with 
the durability procedure.
    (i) Evaluation of the certification durability procedures based on 
in-use emissions data. (1) Manufacturers must use the information 
gathered from the IUVP, as well as other sources of in-use emissions 
data, to periodically review whether the durability procedure it employs 
achieves the objective specified in paragraph (a) of this section.

[[Page 1027]]

    (2) Required analysis of a manufacturer's approved durability 
procedures. (i) In addition to any periodic reviews under paragraph 
(i)(1) of this section, a manufacturer must conduct a review of whether 
the durability procedure it employs achieves the durability objective 
specified in paragraph (a) of this section when the criteria for 
additional testing specified in Sec.86.1846 (b) are activated.
    (ii) These criteria are evaluated independently for all applicable 
FTP emission constituents.
    (iii) This analysis must be performed for each test group certified 
by the manufacturer.
    (iv) These procedures apply to the EPA standard durability 
procedures discussed in paragraphs (c) and (d) of this section as well 
as durability procedures approved under paragraph (e) of this section, 
including modifications under paragraph (h) of this section.
    (v) The analysis must be submitted to EPA no later than 60 days 
after the submission of the IUVP data report specified in Sec.
86.1847(f).
    (3) EPA may require a manufacturer to perform an analysis as 
described in paragraph (i)(2) of this section if EPA is concerned that 
the manufacturer's durability procedure may not achieve the durability 
objective of paragraph (a) of this section.
    (j) If, based on the analysis required in paragraph (i) of this 
section and/or any other information, EPA determines that the durability 
procedure does not achieve the durability objective of paragraph (a) of 
this section, EPA may withdraw approval to use the durability procedure 
or condition approval on modifications to the durability procedure. Such 
withdrawal or conditional approval will apply to future applications for 
certification and to the portion of the manufacturer's product line (or 
the entire product line) that the Administrator determines to be 
affected. Prior to such a withdrawal the Administrator will give the 
manufacturer a preliminary notice at least 60 days prior to the final 
decision. During this period, the manufacturer may submit technical 
discussion, statistical analyses, additional data, or other information 
which is relevant to the decision. The Administrator will consider all 
information submitted by the deadline before reaching a final decision.
    (k) If EPA withdraws approval, under the provisions of paragraph (j) 
of this section, for a durability procedure approved under the 
provisions of paragraphs (c) and/or (d) of this section, the following 
procedures apply:
    (1) The manufacturer must select one of the following options for 
future applications for certification for the applicable portion of the 
manufacturers product-line affect by the Agency's decision:
    (i) Increase future DFs calculated using the applicable durability 
process by the average percent-difference between certification levels 
and IUVP data; or
    (ii) Increase the miles driven on the SRC or the aging time 
calculated by the BAT equation by the average percent-difference between 
certification levels and IUVP data, or
    (iii) The manufacturer may obtain approval for a new customized 
durability process, as allowed in paragraph (e) of this section, that 
has been demonstrated to meet the durability objective.
    (2) If EPA's decision to withdraw approval under the provisions of 
paragraph (j) of this section is based on fewer than 20 tests, the 
Administrator may require a smaller adjustment than specified in 
paragraph (k)(1)(i) or (ii) of this section.
    (l) Any manufacturer may request a hearing on the Administrator's 
withdrawal of approval in paragraphs (j) or (k) of this section. The 
request must be in writing and must include a statement specifying the 
manufacturer's objections to the Administrator's determinations, and 
data in support of such objection. If, after review of the request and 
supporting data, the Administrator finds that the request raises a 
substantial factual issue, she/he must provide the manufacturer a 
hearing in accordance with Sec.86.1853-01 with respect to such issue.
    (m) Durability demonstration procedures for vehicles subject to the 
greenhouse gas exhaust emission standards specified in Sec.86.1818. 
(1) CO2. (i) Unless otherwise specified under paragraph 
(m)(1)(ii) of this section, manufacturers

[[Page 1028]]

may use a multiplicative CO2 deterioration factor of one or 
an additive deterioration factor of zero to determine full useful life 
emissions for the FTP and HFET tests.
    (ii) Based on an analysis of industry-wide data, EPA may 
periodically establish and/or update the deterioration factor for 
CO2 emissions, including air conditioning and other credit-
related emissions. Deterioration factors established and/or updated 
under this paragraph (m)(1)(ii) will provide adequate lead time for 
manufacturers to plan for the change.
    (iii) Alternatively, manufacturers may use the whole-vehicle mileage 
accumulation procedures in Sec.86.1823-08 (c) or (d)(1) to determine 
CO2 deterioration factors. In this case, each FTP test 
performed on the durability data vehicle selected under Sec.86.1822 
must also be accompanied by an HFET test, and combined FTP/HFET 
CO2 results determined by averaging the city (FTP) and 
highway (HFET) CO2 values, weighted 0.55 and 0.45 
respectively. The deterioration factor will be determined for this 
combined CO2 value. Calculated multiplicative deterioration 
factors that are less than one shall be set to equal one, and calculated 
additive deterioration factors that are less than zero shall be set to 
zero.
    (iv) If, in the good engineering judgment of the manufacturer, the 
deterioration factors determined according to paragraphs (m)(1)(i), 
(m)(1)(ii), or (m)(1)(iii) of this section do not adequately account for 
the expected CO2 emission deterioration over the vehicle's 
useful life, the manufacturer may petition EPA to request a more 
appropriate deterioration factor.
    (2) N2O and CH4. (i) For manufacturers 
complying with the FTP emission standards for N2O and 
CH4 specified in Sec.86.1818-12(f)(1) or determined under 
Sec.86.1818-12(f)(3), FTP-based deterioration factors for 
N2O and CH4 shall be determined according to the 
provisions of paragraphs (a) through (l) of this section.
    (ii) For manufacturers complying with the fleet averaging option for 
N2O and CH4 as allowed under Sec.86.1818-
12(f)(2), deterioration factors based on FTP testing shall be determined 
and may be used to determine full useful life emissions for the FTP and 
HFET tests. The manufacturer may at its option determine separate 
deterioration factors for the FTP and HFET test cycles, in which case 
each FTP test performed on the durability data vehicle selected under 
Sec.86.1822 of this part must also be accompanied by an HFET test.
    (iii) For the 2012 through 2016 model years only, manufacturers may 
use alternative deterioration factors. For N2O, the 
alternative deterioration factor to be used to adjust FTP and HFET 
emissions is the deterioration factor determined for (or derived from, 
using good engineering judgment) NOX emissions according to 
the provisions of this section. For CH4, the alternative 
deterioration factor to be used to adjust FTP and HFET emissions is the 
deterioration factor determined for (or derived from, using good 
engineering judgment) NMOG or NMHC emissions according to the provisions 
of this section.
    (3) Other carbon-related exhaust emissions. FTP-based deterioration 
factors shall be determined for carbon-related exhaust emissions (CREE), 
hydrocarbons, and CO according to the provisions of paragraphs (a) 
through (l) of this section. The FTP-based deterioration factor shall be 
used to determine full useful life emissions for both the FTP (city) and 
HFET (highway) test cycles. The manufacturer may at its option determine 
separate deterioration factors for the FTP and HFET test cycles, in 
which case each FTP test performed on the durability data vehicle 
selected under Sec.86.1822 must also be accompanied by an HFET test. 
In lieu of determining emission-specific deterioration factors for the 
specific hydrocarbons of CH3OH (methanol), HCHO 
(formaldehyde), C2H5OH (ethanol), and 
C2H4O (acetaldehyde) as may be required for some 
alternative fuel vehicles, manufacturers may use the additive or 
multiplicative deterioration factor determined for (or derived from, 
using good engineering judgment) NMOG or NMHC emissions according to the 
provisions of this section.
    (4) Air Conditioning leakage and efficiency or other emission credit 
requirements to comply with exhaust CO2 standards. 
Manufactures will attest to the

[[Page 1029]]

durability of components and systems used to meet the CO2 
standards. Manufacturers may submit engineering data to provide 
durability demonstration. Deterioration factors do not apply to 
emission-related components and systems used to generate air 
conditioning leakage and/or efficiency credits.
    (n) Emission component durability. [Reserved]. For guidance see 40 
CFR 86.1823-01(e).

Sec.86.1824-01  Durability demonstration procedures for evaporative 
emissions.

    This section applies to gasoline-, methanol-, liquefied petroleum 
gas-, and natural gas-fueled LDV/Ts, MDPVs, complete heavy-duty 
vehicles, and heavy-duty vehicles certified under the provisions of 
Sec.86.1801-01(c). The manufacturer shall determine a durability 
process that will predict the expected evaporative emission 
deterioration of candidate in-use vehicles over their full useful life. 
The manufacturer shall use good engineering judgment in determining this 
process.
    (a) Service accumulation method. (1) The manufacturer shall develop 
a service accumulation method designed to effectively predict the 
deterioration of candidate in-use vehicles' evaporative emissions in 
actual use over its full useful life. The manufacturer shall use good 
engineering judgement in developing this method.
    (2) The manufacturers may develop a service accumulation methods 
based upon whole-vehicle full-mileage accumulation, whole vehicle 
accelerated mileage accumulation (e.g., where 40,000 miles on a severe 
mileage accumulation cycle is equivalent to 100,000 miles of normal in-
use driving), bench aging of individual components or systems, or other 
approaches approved by the Administrator.
    (i) For whole vehicle mileage accumulation programs, all emission 
control components and systems (including both hardware and software) 
must be installed and operating for the entire mileage accumulation 
period.
    (ii) Bench procedures shall simulate the aging of components or 
systems over the applicable useful life and shall simulate driving 
patterns and vehicle operational environments found in actual use. For 
this purpose, manufacturers may remove the emission-related components 
(and other components), in whole or in part, from the durability vehicle 
itself and deteriorate them independently. Vehicle testing for the 
purpose of determining deterioration factors may include the testing of 
durability vehicles that incorporate such bench-aged components.
    (iii) For gasoline fueled vehicles certified to meet the evaporative 
emission standards set forth in Sec.86.1811-04(e)(1), any service 
accumulation method for evaporative emissions must employ gasoline fuel 
for the entire service accumulation period which contains ethanol in, at 
least, the highest concentration permissible in gasoline under federal 
law and that is commercially available in any state in the United 
States. Unless otherwise approved by the Administrator, the manufacturer 
must determine the appropriate ethanol concentration by selecting the 
highest legal concentration commercially available during the calendar 
year before the one in which the manufacturer begins its service 
accumulation. The manufacturer must also provide information acceptable 
to the Administrator to indicate that the service accumulation method is 
of sufficient design, duration and severity to stabilize the 
permeability of all non-metallic fuel and evaporative system components 
to the service accumulation fuel constituents.
    (iv) For flexible-fueled, dual-fueled, multi-fueled, ethanol-fueled 
and methanol-fueled vehicles certified to meet the evaporative emission 
standards set forth in Sec.86.1811-04(e)(1), any service accumulation 
method must employ fuel for the entire service accumulation period which 
the vehicle is designed to use and which the Administrator determines 
will have the greatest impact upon the permeability of evaporative and 
fuel system components. The manufacturer must also provide information 
acceptable to the Administrator to indicate that the

[[Page 1030]]

service accumulation method is of sufficient design, duration and 
severity to stabilize the permeability of all non-metallic fuel and 
evaporative system components to service accumulation fuel constituents.
    (v) A manufacturer may use other methods, based upon good 
engineering judgment, to meet the requirements of paragraphs (a)(2) 
(iii) and (iv) of this section, as applicable. These methods must be 
approved in advance by the Administrator and meet the objectives of 
paragraphs (a)(2) (iii) and (iv) of this section, as applicable: to 
provide assurance that the permeability of all non-metallic fuel and 
evaporative system components will not lead to evaporative emission 
standard exceedance under sustained exposure to commercially available 
alcohol-containing fuels for the useful life of the vehicle.
    (b) Vehicle/component selection method. The manufacturer shall 
determine a vehicle and component selection procedure which results in 
representative test vehicles and reflects good engineering judgment.
    (c) The manufacturer shall calculate a deterioration factor which is 
applied to the evaporative emission results of the emission data 
vehicles. The deterioration factor shall be based on a linear 
regression, or an other regression technique approved in advance by the 
Administrator. The DF will be calculated to be the difference between 
the full life mileage evaporative level minus the stabilized mileage 
(e.g., 4000-mile) evaporative level from the regression analysis. The DF 
and the full and stabilized mileage emission levels shall be rounded to 
two decimal places of accuracy in accordance with the Rounding-Off 
Method specified in ASTM E29-93a, Standard Practice for Using 
Significant Digits in Test Data to Determine Conformance with 
Specifications (incorporated by reference, see Sec.86.1(b)(1). 
Calculated DF values of less than zero shall be changed to zero for the 
purposes of this paragraph.
    (d) Emission component durability. The manufacturer shall use good 
engineering judgment to determine that all emission-related components 
are designed to operate properly for the full useful life of the 
vehicles in actual use.
    (e) In-use verification. The durability program must meet the 
requirements of Sec.86.1845-01.
    (f) Information obtained under Sec. Sec.86.1845-01, 86.1846-01, 
86.1847-01 or from other sources shall be used by the manufacturer in 
developing new durability processes and/or updating existing durability 
processes using good engineering judgment.

Sec.86.1824-07  Durability demonstration procedures for evaporative
emissions.

    Sec.86.1824-07 includes text that specifies requirements that 
differ from those specified in Sec.86.1824-01. Where a paragraph in 
Sec.86.1824-01 is identical and applicable to Sec.86.1824-07, this 
may be indicated by specifying the corresponding paragraph and the 
statement ``[Reserved]. For guidance see Sec.86.1824-01.''. This 
section applies to gasoline-, methanol-, natural gas- and liquefied 
petroleum gas-fueled LDV/Ts, MDPVs, and HDVs.
    (a) through (f) [Reserved]. For guidance see Sec.86.1824-01.

[66 FR 5192, Jan. 18, 2001]



Sec.86.1824-08  Durability demonstration procedures for evaporative
emissions.

    This section describes durability demonstration procedures for 
evaporative emissions. Eligible small-volume manufacturers or small-
volume test groups may optionally meet the requirements of Sec. Sec.
86.1826 and 86.1838 instead of the requirements of paragraphs (a) 
through (j) of this section. A separate durability demonstration is 
required for each evaporative/refueling family.
    (a) Durability program objective. The durability program must 
predict an expected in-use emission deterioration rate and emission 
level that effectively represents a significant majority of the 
distribution of emission levels and deterioration in actual use over the 
full useful life of candidate in-use vehicles of each vehicle design 
which uses the durability program. This requirement applies for all 
SHED-based measurements except the bleed emission test.

[[Page 1031]]

The standard for bleed emissions applies for the full useful life, but 
manufacturers do not need to establish deterioration factors for bleed 
emissions. The requirements of this section do not apply for spitback or 
leak standards.
    (b) Required durability demonstration. Manufacturers must conduct a 
durability demonstration which satisfies the provisions of either 
paragraph (c), (d), or (e) of this section.
    (c) Whole vehicle evaporative durability demonstration. (1) Mileage 
accumulation must be conducted using the SRC or any road cycle approved 
under the provisions of Sec.86.1823(e)(1).
    (2) Mileage accumulation must be conducted for either:
    (i) The applicable full useful life mileage period specified in 
Sec.86.1805, or
    (ii) At least 75 percent of the full useful life mileage. In which 
case, the manufacturer must calculate a df calculated according to the 
procedures of paragraph (f)(1)(ii) of this section, except that the DF 
must be based upon a line projected to the full-useful life mileage 
using the upper 80 percent statistical confidence limit calculated from 
the emission data.
    (3) The manufacturer must conduct at least one evaporative emission 
test at each of the five different mileage points selected using good 
engineering judgement. The required testing must include testing at 
5,000 miles and at the highest mileage point run during mileage 
accumulation (e.g. the full useful life mileage). Additional testing may 
be conducted by the manufacturer using good engineering judgement. The 
manufacturer may select to run either the 2-day and/or 3-day evaporative 
test at each test point using good engineering judgement.
    (d) Bench aging evaporative durability procedures. Manufacturers may 
use bench procedures designed, using good engineering judgement, to 
evaluate the emission deterioration of evaporative control systems. 
Manufacturers may base the bench procedure on an evaluation the 
following potential causes of evaporative emission deterioration:
    (1) Cycling of canister loading due to diurnal and refueling events,
    (2) Use of various commercially available fuels, including the Tier 
2 requirement to include alcohol fuel;
    (3) Vibration of components;
    (4) Deterioration of hoses, etc. due to environmental conditions; 
and
    (5) Deterioration of fuel cap due to wear.
    (e) Combined whole-vehicle and bench-aging programs. Manufacturers 
may combine the results of whole vehicle aging and bench aging 
procedures using good engineering judgement.
    (f) Fuel requirements. (1) For gasoline fueled vehicles certified to 
meet the evaporative emission standards set forth in this subpart, any 
mileage accumulation method for evaporative emissions must employ 
gasoline fuel for the entire mileage accumulation period which contains 
ethanol in, at least, the highest concentration permissible in gasoline 
under federal law and that is commercially available in any state in the 
United States. Unless otherwise approved by the Administrator, the 
manufacturer must determine the appropriate ethanol concentration by 
selecting the highest legal concentration commercially available during 
the calendar year before the one in which the manufacturer begins its 
mileage accumulation. The manufacturer must also provide information 
acceptable to the Administrator to indicate that the mileage 
accumulation method is of sufficient design, duration and severity to 
stabilize the permeability of all non-metallic fuel and evaporative 
system components to the mileage accumulation fuel constituents.
    (2) For flexible-fueled, dual-fueled, multi-fueled, ethanol-fueled 
and methanol-fueled vehicles certified to meet the evaporative emission 
standards set forth in Sec.86.1811-04(e)(1), any mileage accumulation 
method must employ fuel for the entire mileage accumulation period which 
the vehicle is designed to use and which the Administrator determines 
will have the greatest impact upon the permeability of evaporative and 
fuel system components. The manufacturer must also provide information 
acceptable to the Administrator to indicate that the mileage 
accumulation method is of sufficient design, duration and severity to 
stabilize the permeability of all non-metallic fuel and evaporative 
system

[[Page 1032]]

components to mileage accumulation fuel constituents.
    (3) A manufacturer may use other methods, based upon good 
engineering judgment, to meet the requirements of paragraphs (f)(1) and 
(2) of this section, as applicable. These methods must be approved in 
advance by the Administrator and meet the objectives of paragraphs 
(f)(1) and (2) of this section, as applicable: to provide assurance that 
the permeability of all non-metallic fuel and evaporative system 
components will not lead to evaporative emission standard exceedance 
under sustained exposure to commercially available alcohol-containing 
fuels for the useful life of the vehicle.
    (g) Calculation of a deterioration factor. The manufacturer must 
calculate a deterioration factor which is applied to the evaporative 
emission results of the emission data vehicles. The deterioration factor 
must be based on a linear regression, or an other regression technique 
approved in advance by the Administrator. The DF will be calculated to 
be the difference between the full life mileage evaporative level minus 
the stabilized mileage (e.g., 4000-mile) evaporative level from the 
regression analysis. The full useful life regressed emission value, the 
stabilized mileage regressed emission value, and the DF result must be 
rounded to the same precision and using the same procedures as the raw 
emission results according to the provisions of Sec.86.1837-01. 
Calculated DF values of less than zero must be changed to zero for the 
purposes of this paragraph.
    (h) [Reserved]
    (i) If EPA determines based on IUVP data or other information that 
the durability procedure does not achieve the durability objective of 
paragraph (a) of this section, EPA may withdraw approval to use the 
durability procedure or condition approval on modifications to the 
durability procedure. Such withdrawal or conditional approval will apply 
to future applications for certification and to the portion of the 
manufacturer's product line (or the entire product line) that the 
Administrator determines to be affected. Prior to such a withdrawal the 
Administrator will give the manufacturer a preliminary notice at least 
60 days prior to the final decision. During this period, the 
manufacturer may submit technical discussion, statistical analyses, 
additional data, or other information which is relevant to the decision. 
The Administrator will consider all information submitted by the 
deadline before reaching a final decision.
    (j) Any manufacturer may request a hearing on the Administrator's 
withdrawal of approval in paragraph (i) of this section. The request 
must be in writing and must include a statement specifying the 
manufacturer's objections to the Administrator's determinations, and 
data in support of such objection. If, after review of the request and 
supporting data, the Administrator finds that the request raises a 
substantial factual issue, she/he must provide the manufacturer a 
hearing in accordance with Sec.86.1853-01 with respect to such issue.

emissions.

    This section applies to 2008 and later model year light-duty 
vehicles, light-duty trucks, and heavy-duty vehicles which are certified 
under light-duty rules as allowed under the provisions of Sec.86.1801-
01(c)(1) which are subject to refueling loss emission compliance. 
Optionally, a manufacturer may elect to use this section for earlier

refueling standards to different classes of vehicles for various model 
years. Diesel fuel vehicles may qualify for an exemption to the 
requirements of this section under the provisions of Sec.86.1810.

[[Page 1034]]

    (a) Durability program objective. The durability program must 
predict an expected in-use emission deterioration rate and emission 
level that effectively represents a significant majority of the 
distribution of emission levels and deterioration in actual use over the 
full useful life of candidate in-use vehicles of each vehicle design 
which uses the durability program.
    (b) Required durability demonstration. Manufacturers must conduct a 
durability demonstration which satisfies the provisions of either 
paragraph (c), (d), or (e) of this section.
    (c) Whole vehicle refueling durability demonstration. The following 
procedures must be used when conducting a whole vehicle durability 
demonstration:
    (1) Mileage accumulation must be conducted using the SRC or a road 
cycle approved under the provisions of Sec.86.1823(e)(1).
    (2) Mileage accumulation must be conducted for either:
    (i) The applicable full useful life mileage period specified in 
Sec.86.1805, or
    (ii) At least 75 percent of the full useful life mileage. In which 
case, the manufacturer must calculate a df calculated according to the 
procedures of paragraph (f)(1)(ii) of this section, except that the DF 
must be based upon a line projected to the full-useful life mileage 
using the upper 80 percent statistical confidence limit calculated from 
the emission data.
    (3) The manufacturer must conduct at least one refueling emission 
test at each of the five different mileage points selected using good 
engineering judgement. The required testing must include testing at 
5,000 miles and at the highest mileage point run during mileage 
accumulation (e.g. the full useful life mileage). Additional testing may 
be conducted by the manufacturer using good engineering judgement.
    (d) Bench aging refueling durability procedures. Manufacturers may 
use bench procedures designed, using good engineering judgement, to 
evaluate the emission deterioration of evaporative/refueling control 
systems. Manufacturers may base the bench procedure on an evaluation the 
following potential causes of evaporative/refueling emission 
deterioration:
    (1) Cycling of canister loading due to diurnal and refueling events;
    (2) Use of various commercially available fuels, including the Tier 
2 requirement to include alcohol fuel;
    (3) Vibration of components;
    (4) Deterioration of hoses, etc. due to environmental conditions; 
and
    (5) Deterioration of fuel cap due to wear.
    (e) Combined whole-vehicle and bench-aging programs. Manufacturers 
may combine the results of whole vehicle aging and bench aging 
procedures using good engineering judgement.
    (f) [Reserved]
    (g) Calculation of a deterioration factor. The manufacturer must 
calculate a deterioration factor which is applied to the evaporative 
emission results of the emission data vehicles. The deterioration factor 
must be based on a linear regression, or an other regression technique 
approved in advance by the Administrator. The DF will be calculated to 
be the difference between the full life mileage evaporative level minus 
the stabilized mileage (e.g., 4000-mile) evaporative level from the 
regression analysis. The full useful life regressed emission value, the 
stabilized mileage regressed emission value, and the DF result must be 
rounded to the same precision and using the same procedures as the raw 
emission results according to the provisions of Sec.86.1837-01. 
Calculated DF values of less than zero must be changed to zero for the 
purposes of this paragraph.
    (h) Emission component durability. [Reserved]. For guidance see 40 
CFR 86.1845-01 (e).
    (i) If EPA determines based on IUVP data or other information that 
the durability procedure does not achieve the durability objective of 
paragraph (a) of this section, EPA may withdraw approval to use the 
durability procedure or condition approval on modifications to the 
durability procedure. Such withdrawal or conditional approval will apply 
to future applications for certification and to the portion of the 
manufacturer's product line (or the entire product line) that the 
Administrator determines to be affected. Prior to such a withdrawal the 
Administrator will give the manufacturer a preliminary notice at least 
60 days prior to the final

[[Page 1035]]

decision. During this period, the manufacturer may submit technical 
discussion, statistical analyses, additional data, or other information 
which is relevant to the decision. The Administrator will consider all 
information submitted by the deadline before reaching a final decision.
    (j) Any manufacturer may request a hearing on the Administrator's 
withdrawal of approval in paragraph (i) of this section. The request 
must be in writing and must include a statement specifying the 
manufacturer's objections to the Administrator's determinations, and 
data in support of such objection. If, after review of the request and 
supporting data, the Administrator finds that the request raises a 
substantial factual issue, she/he must provide the manufacturer a 
hearing in accordance with Sec.86.1853-01 with respect to such issue.

Sec.86.1826-01  Assigned deterioration factors for small-volume
manufacturers and small-volume test groups.

    (a) Applicability. This program is an option available for small-
volume manufacturers and small-volume test groups as described in Sec.
86.1838.
    (b) Determination of deterioration factors. No service accumulation 
method or vehicle/component selection method is required. Deterioration 
factors for all types of regulated emissions are assigned using the 
provisions in this paragraph (b). A separate assigned deterioration 
factor is required for each durability group. Manufacturers shall use 
good engineering judgment in applying deterioration factors. 
Manufacturers may use assigned deterioration factors that the 
Administrator determines and prescribes.
    (1) The deterioration factors will be the Administrator's estimate, 
periodically updated and published in a guidance document, of the 70th 
percentile deterioration factors calculated using the industry-wide 
database of previously completed durability data vehicles or engines 
used for certification.
    (2) The Administrator may use discretion to develop assigned 
deterioration factors using alternative methods if there is insufficient 
information to calculate an appropriate industry-wide deterioration 
factor (for example: a new engine technology coupled with a proven 
emission control system). These methods may include the use of assigned 
deterioration factors based on similar durability vehicles.
    (3) Alternatively, with advance approval from the Administrator, a 
manufacturer may use deterioration factors developed by another 
manufacturer. The manufacturer seeking to use these deterioration 
factors must--
    (i) Demonstrate that the engines from the two manufacturers share 
technical parameters to the degree that would support the conclusion 
that a common deterioration factor should apply for both vehicle 
configurations as defined in Sec.86.1803.
    (ii) Provide supporting information, such as histograms of exhaust 
temperature data, comparisons of vehicle weight and road load 
horsepower, or comparisons of powertrains and emission control systems.

Sec.86.1827-01  Test group determination.

    This section applies to the grouping of vehicles into test groups 
within a durability group. The vehicles covered by an application within 
a durability group shall be divided into test groups based on the 
following criteria. The manufacturer shall use good engineering judgment 
in grouping vehicles into test groups.
    (a) To be included in the same test group, vehicles must be 
identical in all following respects:
    (1) Durability group;
    (2) Engine displacement (within a total band width of 15 percent of 
the largest displacement or 50 CID, whichever is larger);
    (3) Number of cylinders or combustion chambers;
    (4) Arrangement of cylinders or combustion chambers (e.g. in-line, 
v-shaped);
    (5) Subject to the same emission standards (except for 
CO2), or FEL in the case of cold temperature NMHC standards, 
except that a manufacturer may request to group vehicles into the same 
test group as vehicles subject to more stringent standards, so long as 
all the vehicles within the test group are

[[Page 1036]]

certified to the most stringent standards applicable to any vehicle 
within that test group. Light-duty trucks and light-duty vehicles may be 
included in the same test group if all vehicles in the test group are 
subject to the same emission standards, with the exception of the 
CO2 standard and/or the total HC standard.
    (b) Where vehicles are of a type which cannot be divided into test 
groups based on the criteria listed above (such as non-cylinder 
engines), the Administrator will establish test groups for those 
vehicles based upon the features most related to their exhaust emission 
characteristics.
    (c) Manufacturers may further divide groups determined under 
paragraph (a) of this section providing the Administrator is notified in 
advance of any such changes in writing.
    (d) Manufacturers may request the Administrator's approval to 
combine vehicles into a single test group which would normally not be 
eligible to be in a single test group. The petition should provide:
    (1) Substantial evidence that all the vehicles in the larger 
grouping will have the similar levels of emissions;
    (2) Evidence of equivalent component durability over the vehicle's 
useful life;
    (3) Evidence that the groups will result in sufficient in-use 
verification program data, appropriate tracking in use, and clear 
liability for the Agency's recall program; and
    (4) A statement that all vehicles within a test group are certified 
to the most stringent standards applicable to any vehicle within that 
test group.
    (e) Unless otherwise approved by the Administrator, a manufacturer 
of hybrid electric vehicles must create separate test groups based on 
both the type of battery technology employed by the HEV and upon 
features most related to their exhaust emission characteristics.
    (f) Unless otherwise approved by the Administrator, a manufacturer 
of electric vehicles must create separate test groups based on the type 
of battery technology, the capacity and voltage of the battery, and the 
type and size of the electric motor.

Sec.86.1828-01  Emission data vehicle selection.

    (a) FTP and SFTP testing. Within each test group, the vehicle 
configuration shall be selected which is expected to be worst-case for 
exhaust emission compliance on candidate in-use vehicles, considering 
all exhaust emission constituents, all exhaust test procedures, and the 
potential impact of air conditioning on test results. The selected 
vehicle will include an air conditioning engine code unless the worst-
case vehicle configuration selected is not available with air 
conditioning. This vehicle configuration will be used as the EDV 
calibration.
    (b) Evaporative/Refueling testing. Vehicles of each evaporative/
refueling family will be divided into evaporative/refueling emission 
control systems.
    (1) The vehicle configuration expected to exhibit the highest 
evaporative and/or refueling emission on candidate in-use vehicles shall 
be selected for each evaporative/refueling family and evaporative 
refueling emission system combination from among the corresponding 
vehicles selected for FTP and SFTP testing under paragraph (a) of this 
section. Separate vehicles may be selected to be tested for evaporative 
and refueling testing.
    (2) Each test group must be represented by both evaporative and 
refueling testing (provided that the refueling standards are applicable) 
before it may be certified. That required testing may have been 
conducted on a vehicle in another test group provided the tested vehicle 
is a member of the same evaporative/refueling family and evaporative/
refueling emission system combination and it was selected for testing in 
accordance with the provisions of paragraph (b)(1) of this section.
    (3) For evaporative/refueling emission testing, the vehicle(s) 
selected shall be equipped with the worst-case evaporative/refueling 
emission hardware available on that vehicle considering such items as 
canister size and

[[Page 1037]]

material, fuel tank size and material, purge strategy and flow rates, 
refueling characteristics, and amount of vapor generation.
    (c) Cold CO testing. For cold temperature CO exhaust emission 
compliance for each durability group, the vehicle expected to emit the 
highest CO emissions at 20 degrees F on candidate in-use vehicles shall 
be selected from the test vehicles selected in accordance with paragraph 
(a) of this section.
    (d) [Reserved]
    (e) The manufacturer may select, using good engineering judgement, 
an equivalent or worst-case configuration in lieu of testing the vehicle 
selected in paragraphs (a) through (d) of this section. Carryover data 
satisfying the provisions of Sec.86.1839-01 may also be used in lieu 
of testing the configuration selected in paragraphs (a) through (d) of 
this section.
    (f) The manufacturer shall use good engineering judgment in making 
selections of vehicles under this section.
    (g) Cold temperature NMHC testing. For cold temperature NMHC exhaust 
emission compliance for each durability group, the manufacturer must 
select the vehicle expected to emit the highest NMHC emissions at 20 
[deg]F on candidate in-use vehicles from the test vehicles specified in 
paragraph (a) of this section. When the expected worst-case cold 
temperature NMHC vehicle is also the expected worst-case cold 
temperature CO vehicle as selected in paragraph (c) of this section, 
then cold temperature testing is required only for that vehicle; 
otherwise, testing is required for both the worst-case cold temperature 
CO vehicle and the worst-case cold temperature NMHC vehicle.

appropriate information and good engineering judgment.
    (B) In lieu of testing an Otto-cycle light-duty vehicle, light-duty 
truck, or heavy-duty vehicle for particulate emissions for 
certification, a manufacturer may provide a statement in its application 
for certification that such vehicles comply with the applicable 
standards. Such a statement must be

[[Page 1038]]

based on previous emission tests, development tests, or other 
appropriate information and good engineering judgment.
    (C) [Reserved]
    (D) A manufacturer may petition the Administrator to waive the 
requirement to measure particulate emissions when conducting Selective 
Enforcement Audit testing of Otto-cycle vehicles.
    (E) In lieu of testing a gasoline, diesel, natural gas, liquefied 
petroleum gas, or hydrogen fueled Tier 2 or interim non-Tier 2 vehicle 
for formaldehyde emissions when such vehicles are certified based upon 
NMHC emissions, a manufacturer may provide a statement in its

emission tests, development tests, or other appropriate information and 
good engineering judgment.
    (G) For the 2012 through 2016 model years, in lieu of testing a 
vehicle for N2O emissions, a manufacturer may provide a 
statement in its application for certification that such vehicles comply 
with the applicable standards. Such a statement may also be used for 
2017 and 2018 model year vehicles only if the application for 
certification for those vehicles is based upon data carried over from a 
prior model year, as allowed under this subpart. No 2019 and later model 
year vehicles may be waived from testing for N2O emissions. 
Such a statement must be based on previous emission tests, development 
tests, or other appropriate information and good engineering judgment. 
Vehicles certified to N2O standards using a compliance 
statement in lieu of submitting test data are not required to collect 
and submit N2O emission data under the in-use verification 
testing requirements of Sec.86.1845.
    (2) Evaporative/Refueling testing. Vehicles of each evaporative/
refueling family will be divided into evaporative/refueling emission 
control systems. Applicability of the refueling test requirements of 
this paragraph shall be determined in accordance with the applicability 
of the refueling loss standards under the provisions of Sec.86.1810.
    (i) Testing at low altitude. One EDV in each evaporative/refueling 
family and evaporative/refueling emission control system combination 
must be tested in accordance with the evaporative/refueling test 
procedure requirement of subpart B of this part. The configuration of 
the EDV will be determined under the provisions of Sec.86.1828-01. The 
EDV must also be tested for exhaust emission compliance using the FTP 
and SFTP procedures of subpart B of this part. In lieu of testing 
natural gas or hydrogen fueled vehicles to demonstrate compliance with 
the evaporative and refueling emission standards specified in this 
subpart, a manufacturer may provide a statement in its application for 
certification that, based on the manufacturer's engineering evaluation 
of appropriate testing and/or design parameters, all light-duty 
vehicles, light-duty trucks, and complete heavy-duty vehicles comply 
with applicable emission standards. This same testing exemption applies 
for vehicles fueled by liquefied petroleum gas, except that refueling 
tests are required for systems that allow venting during the refueling 
operation.
    (ii) Testing at high altitude. For high-altitude evaporative and/or 
refueling emission compliance for each evaporative/refueling family, the 
manufacturer shall follow one of the following two procedures:
    (A) One EDV in each evaporative/refueling family and evaporative/
refueling emission control system combination shall be tested in 
accordance with the evaporative/refueling test procedure requirement of 
subpart B of this part. The configuration of the EDV will be determined 
under the provisions of Sec.86.1824-01. The EDV must also be tested 
for exhaust emissions using the FTP procedures of subpart B of this part 
while operated at high altitude; or

[[Page 1039]]

    (B) In lieu of testing vehicles according to the provisions of 
paragraph (b)(2)(ii)(A) of this section, a manufacturer may provide a 
statement in its application for certification that, based on the 
manufacturer's engineering evaluation of such high-altitude emission 
testing as the manufacturer deems appropriate, all light-duty vehicles, 
light-duty trucks, and complete heavy-duty vehicles comply with the 
emission standards at high altitude.
    (iii) Optional waiver of two-diurnal evaporative certification test 
for gasoline- and ethanol-fueled vehicles. In lieu of testing gasoline-
fueled and ethanol-fueled vehicles for the supplemental two-diurnal test 
sequence according to the provisions of paragraphs (b)(2)(i) and 
(b)(2)(ii) of this section, a manufacturer may optionally provide a 
statement of compliance in its application for certification that, based 
on the manufacturer's good engineering judgement, all light-duty 
vehicles, light-duty trucks and complete heavy-duty vehicles in the 
applicable evaporative/refueling emission family comply with the 
evaporative emission standard for the supplemental two-diurnal test 
sequence.
    (A) The option to provide a statement of compliance in lieu of 2-
diurnal evaporative certification test data outlined in paragraph 
(b)(2)(iii) of this section is limited to vehicles with conventional 
evaporative emission control systems (as determined by the 
Administrator). This option may be used for vehicles in evaporative/
refueling families which are certified to the applicable two-diurnal, 
three-diurnal, running loss, and refueling emission standards. EPA may 
perform confirmatory 2-diurnal evaporative emission testing on 
certification test vehicles which are certified using this option (even 
though the manufacturer may not have performed a 2-diurnal evaporative 
test during the certification process). If data shows noncompliance, 
noncompliance will be addressed through 86.1851. As well, if data shows 
noncompliance, EPA may not normally allow for subsequent waivers for the 
applicable evaporative family.
    (B) Manufacturers shall supply information if requested by EPA in 
support of the statement of compliance outlined in paragraph (b)(2)(iii) 
of this section. This information shall include evaporative calibration 
information for the emission-data test vehicle and for other vehicles in 
the evaporative/refueling family, including, but not limited to, 
canister type, canister volume, canister working capacity, fuel tank 
volume, fuel tank geometry, the type of fuel delivery system (return, 
returnless, variable flow fuel pump, etc.), a description of the input 
parameters and software strategy used to control the evaporative 
canister purge, the nominal purge flow volume (in bed volumes) when 
vehicles are driven over the 2-diurnal (FTP) driving cycle, the nominal 
purge flow volume (in bed volumes) when vehicles are driven over the 3-
diurnal (FTP + running loss) driving cycle, and other supporting 
information as necessary to demonstrate that the purge flow rate 
calibration on the 2-diurnal test sequence is adequate to comply with 
the evaporative emission standard for the supplemental two-diurnal test 
sequence.
    (iv) For diesel-fueled light-duty vehicles, a manufacturer may 
provide a statement in the application for certification that vehicles 
comply with the refueling emission standard instead of submitting test 
data. Such a statement must be based on previous emission tests, 
development tests, or other appropriate information, and good 
engineering judgment.
    (3) Cold temperature CO and cold temperature NMHC Testing. The 
manufacturer must test one EDV in each durability group for cold 
temperature CO and cold temperature NMHC exhaust emission compliance in 
accordance with the test procedures in subpart C of this part or with 
alternative procedures approved in advance by the Administrator. The 
selection of which EDV and test group within the durability group will 
be tested for cold temperature CO and cold temperature NMHC compliance 
will be determined under the provisions of Sec.86.1828-10(c) and (g).
    (4) Electric vehicles and fuel cell vehicles. For electric vehicles 
and fuel cell vehicles, manufacturers may provide a statement in the 
application for certification that vehicles comply with all

testing procedures of subpart B of this part; or
    (ii) In lieu of testing light trucks and complete heavy-duty 
vehicles for idle CO emissions, a manufacturer may provide a statement 
in its application for certification that, based on the manufacturer's 
engineering evaluation of such idle CO testing as the manufacturer deems 
appropriate, all light-duty trucks and complete heavy-duty vehicles 
comply with the idle CO emission standards.
    (c) Running change testing. Running change testing shall be 
conducted as required under the provisions of Sec.86.1842-01.
    (d) [Reserved]

Sec.86.1829-15  Durability and emission testing requirements; waivers.

    This section describes general testing requirements for certifying 
vehicles under this subpart, and includes several provisions allowing 
for statements of compliance instead of testing in certain 
circumstances. Where a manufacturer provides a statement instead of test 
data under this section, it must be based on previous emission tests, 
development tests, or other appropriate information, and on good 
engineering judgment.
    (a) One durability demonstration is required for each durability 
group. The configuration of the DDV is determined according to Sec.
86.1822. The DDV shall be tested and accumulate service mileage 
according to the provisions of Sec. Sec.86.1823, 86.1824, 86.1825, and 
86.1831. Small-volume manufacturers and small-volume test groups may 
optionally use the alternative durability provisions of Sec.86.1838.
    (b) The manufacturer must test EDVs as follows to demonstrate 
compliance with emission standards:
    (1) Test one EDV in each durability group using the test procedures 
in 40 CFR part 1066 to demonstrate compliance with cold temperature CO 
and NMHC exhaust emission standards.
    (2) Test one EDV in each test group using the FTP, SFTP, and HFET 
test procedures in 40 CFR part 1066 to demonstrate compliance with other 
exhaust emission standards.
    (3) Test one EDV in each evaporative/refueling family and 
evaporative/refueling emission control system combination using the test 
procedures in subpart B of this part to demonstrate compliance with 
evaporative and refueling emission standards.
    (c) The manufacturer must demonstrate compliance with emission 
standards at low-altitude conditions as described in paragraph (b) of 
this section. For standards that apply at high-altitude conditions, the 
manufacturer may either perform the same tests or provide a statement in 
the application for certification that, based on an engineering 
evaluation of appropriate testing to measure or simulate high-altitude 
emissions, all vehicles comply with applicable emission standards at 
high altitude.
    (d) Manufacturers may omit exhaust testing for certification in 
certain circumstances as follows:
    (1) For vehicles subject to the Tier 3 PM standards in Sec.
86.1811, a manufacturer may provide a statement in the application for 
certification that vehicles comply with applicable PM standards instead 
of submitting PM test data for a certain number of vehicles. However, 
each manufacturer must test vehicles from a minimum number of durability 
groups as follows:
    (i) Manufacturers with a single durability group subject to the Tier 
3 PM standards in Sec.86.1811 must submit PM test data for that group.
    (ii) Manufacturers with two to eight durability groups subject to 
the Tier 3

[[Page 1041]]

PM standards in Sec.86.1811 must submit PM test data for at least two 
durability groups each model year. EPA will work with the manufacturer 
to select durability groups for testing, with the general expectation 
that testing will rotate to cover a manufacturer's whole product line 
over time. If a durability group has been certified in an earlier model 
year based on submitted PM data, and that durability group is eligible 
for certification using carryover test data, that carryover data may 
count toward meeting the requirements of this paragraph (d)(1), subject 
to the selection of durability groups.
    (iii) Manufacturers with nine or more durability groups subject to 
the Tier 3 PM standards in Sec.86.1811 must submit PM test data for at 
least 25 percent of those durability groups each model year. We will 
work with the manufacturer to select durability groups for testing as 
described in paragraph (d)(1)(ii) of this section.
    (2) Small-volume manufacturers may provide a statement in the 
application for certification that vehicles comply with the applicable 
PM standard instead of submitting test data.
    (3) Manufacturers may omit PM measurements for fuel economy and GHG 
testing conducted in addition to the testing needed to demonstrate 
compliance with the PM emission standards.
    (4) Manufacturers may provide a statement in the application for 
certification that vehicles comply with the applicable formaldehyde 
standard instead of submitting test data.
    (5) When conducting Selective Enforcement Audit testing, a 
manufacturer may petition the Administrator to waive the requirement to 
measure PM emissions and formaldehyde emissions.
    (6) For model years 2012 through 2016, a manufacturer may provide a 
statement in its application for certification that vehicles comply with 
the applicable standards instead of measuring N2O emissions. 
Such a statement may also be used for model year 2017 and 2018 vehicles 
only if the application for certification for those vehicles is based 
upon data carried over from a prior model year, as allowed under this 
subpart. No model year 2019 and later vehicles may be waived from 
testing for N2O emissions. Vehicles certified to 
N2O standards using a compliance statement instead of 
submitting test data are not required to collect and submit 
N2O emission data under the in-use testing requirements of 
Sec.86.1845.
    (e) Manufacturers may omit evaporative or refueling testing for 
certification in certain circumstances as follows:
    (1) For diesel-fueled vehicles, a manufacturer may provide a 
statement in the application for certification that vehicles comply with 
the refueling emission standard instead of submitting test data.
    (2) For vehicles fueled by natural gas, a manufacturer may provide a 
statement in the application for certification that vehicles comply with 
evaporative emission standards instead of submitting test data. 
Compressed natural gas vehicles meeting the requirements for fueling 
connection devices in Sec.86.1813-17(f)(1) are deemed to comply with 
evaporative and refueling emission standards.
    (3) For vehicles fueled by liquefied petroleum gas, a manufacturer 
may provide a statement in the application for certification that 
vehicles comply with evaporative and refueling emission standards 
instead of submitting test data, except that refueling tests are 
required for systems that allow venting during the refueling operation.
    (4) Manufacturers may provide a statement in the application for 
certification that vehicles comply with the leak standard in Sec.
86.1813 instead of submitting test data.
    (5) For vehicles certified to the refueling emission standards in 
Sec. Sec.86.1811 or 86.1813, a manufacturer may provide a statement in 
the application for certification that vehicles comply with the fuel 
dispensing spitback standard instead of submitting test data.
    (6) In lieu of testing vehicles for the supplemental two-diurnal 
test sequence, a manufacturer may optionally provide a statement of 
compliance in its application for certification that, based on the 
manufacturer's good engineering judgment, all vehicles in the 
evaporative/refueling emission family comply with the evaporative 
emission

[[Page 1042]]

standard for the supplemental two-diurnal test sequence.
    (i) The option to provide a statement of compliance in lieu of 2-
diurnal evaporative certification test data is limited to vehicles with 
conventional evaporative emission control systems (as determined by the 
Administrator). EPA may perform confirmatory 2-diurnal evaporative 
emission testing on test vehicles certified using this option. If data 
shows noncompliance, it will be addressed through Sec.86.1851. Also, 
if data shows noncompliance, EPA will generally disallow subsequent 
waivers for the applicable evaporative family.
    (ii) Manufacturers shall supply information if requested by EPA in 
support of the statement of compliance described in this paragraph 
(e)(6). This information shall include evaporative calibration 
information for the emission-data vehicle and for other vehicles in the 
evaporative/refueling family, including, but not limited to, canister 
type, canister volume, canister working capacity, canister shape and 
internal configuration, fuel tank volume, fuel tank geometry, the type 
of fuel delivery system (return, returnless, variable flow fuel pump, 
etc.), a description of the input parameters and software strategy used 
to control the evaporative canister purge, the nominal purge flow volume 
(in bed volumes) when vehicles are driven over the 2-diurnal (FTP) 
driving cycle, the nominal purge flow volume (in bed volumes) when 
vehicles are driven over the 3-diurnal (FTP + running loss) driving 
cycle, and other supporting information as necessary to demonstrate that 
the purge flow rate calibration on the 2-diurnal test sequence is 
adequate to comply with the evaporative emission standard for the 
supplemental two-diurnal test sequence.
    (7) Where a California evaporative emission standard is at least as 
stringent as a comparable federal evaporative emission standard for a 
vehicle, we may accept test data demonstrating compliance with the 
California standard as demonstrating compliance with the comparable 
standard under this subpart. We may require you to provide test data 
clearly demonstrating that a vehicle tested using the California-
specified test procedures will meet the comparable standard under this 
subpart when tested using the test procedures specified in this part.
    (8) Through model year 2019, we may accept test data demonstrating 
compliance with the California refueling emission standard as 
demonstrating compliance with the analogous refueling emission standard 
under this subpart if all the following conditions apply:
    (i) You certified the vehicles in model year 2016 to California's 
refueling emission standards.
    (ii) You are certifying the vehicles to refueling standards for the 
new model year based on carryover data instead of performing new 
testing.
    (iii) You are also certifying the vehicles for evaporative emissions 
based on California test procedures under the provisions of paragraph 
(e)(6) of this section.
    (9) For complete vehicles above 10,000 pounds GVWR with fuel tanks 
exceeding 35 gallons nominal fuel tank capacity, and for any incomplete 
vehicles above 10,000 pounds GVWR, a manufacturer may provide a 
statement in the application for certification that vehicles comply with 
refueling emission standards instead of submitting test data, consistent 
with 40 CFR 1037.103(c).
    (f) For electric vehicles and fuel cell vehicles, manufacturers may 
provide a statement in the application for certification that vehicles 
comply with all the requirements of this subpart instead of submitting 
test data. Tailpipe emissions of regulated pollutants from vehicles 
powered solely by electricity are deemed to be zero.

Sec.86.1830-01  Acceptance of vehicles for emission testing.

    (a) General test vehicle requirements. (1) All test vehicles shall 
be tested in the proper configurations as specified in Sec.86.1822-01, 
Sec.86.1828-01, or Sec.86.1842-01, as applicable for the type of 
test conducted.
    (2) Components affecting emissions which are used to build test 
vehicles shall either be randomly selected production parts or parts 
verified to be in

[[Page 1043]]

the middle 50 percent of the tolerance range. The manufacturer will 
determine which components affect emissions using good engineering 
judgment.
    (3) Test vehicles must have air conditioning installed and 
operational if that configuration is available with air conditioning. 
Optional equipment must be installed or represented on test vehicles 
according to the provisions of Sec.86.1832-01.
    (4) Test vehicles must receive proper scheduled maintenance as 
established by the manufacturer according to the provisions of Sec.
86.1834-01(b) or (c). Unscheduled maintenance must be approved under the 
provisions of Sec.86.1834-01(d).
    (5) Vehicle mileage shall be accumulated in accordance with Sec.
86.1831-01.
    (6) The road load forces and equivalent test weight used during 
testing will be determined according to the provisions of Sec.86.129-
00.
    (7) Test vehicles shall have the appropriate emission testing 
hardware installed (e.g., exhaust pipe testing flange, fuel tank drain, 
access ports to evaporative canisters, and fuel tank heat blanket) and 
shall have tires with appropriate tire wear.
    (b) Special provisions for durability data vehicles. (1) For DDV's, 
the mileage at all test points shall be within 250 miles of the 
scheduled mileage point as required under Sec.86.1823-08(c)(3). 
Manufacturers may exceed the 250 mile upper limit if there are 
logistical reasons for the deviation and the manufacturer determines 
that the deviation will not affect the representativeness of the 
durability demonstration.
    (2) For DDV's aged using the standard or a customized/alternative 
whole-vehicle cycle, all emission-related hardware and software must be 
installed and operational during all mileage accumulation after the 
5000-mile test point.
    (3) DDV's may be reconfigured before the 5000-mile test point 
providing that the representativeness of the emission results will not 
be affected. Manufacturers shall use good engineering judgment in making 
such determinations.
    (c) Special provisions for emission data vehicles. (1) All EDV's 
shall have at least the minimum number of miles accumulated to achieve 
stabilized emission results according to the provisions of Sec.
86.1831-01(c).
    (2) Within a durability group, the manufacturer may alter any 
emission data vehicle (or other vehicles such as current or previous 
model year emission data vehicles, running change vehicles, fuel economy 
data vehicles, and development vehicles) in lieu of building a new test 
vehicle providing that the modification will not impact the 
representativeness of the vehicle's test results. Manufacturers shall 
use good engineering judgment in making such determinations. Development 
vehicles which were used to develop the calibration selected for 
emission data testing may not be used as the EDV for that configuration. 
Vehicles from outside the durability group may be altered with advance 
approval of the Administrator.
    (3) Components used to reconfigure EDV's under the provisions of 
paragraph (c)(2) of this section must be appropriately aged if necessary 
to achieve representative emission results. Manufacturers must determine 
the need for component aging and the type and amount of aging required 
using good engineering judgment.
    (4) Bench-aged hardware may be installed on an EDV for emission 
testing as a method of determining certification levels (projected 
emission levels at full or intermediate useful life) using bench aging 
procedures under the provisions of Sec.86.1823.

Sec.86.1831-01  Mileage accumulation requirements for test vehicles.

    (a) Durability Data Vehicles. (1) The manufacturer must accumulate 
mileage on DDV's using the procedures in Sec.86.1823.
    (2) All tests required by this subpart on durability data vehicles 
shall be conducted within 250 miles of each of the nominal test point 
mileage. This 250 mile test point mileage 
tolerance may be modified with the advance approval of the Administrator 
if the basis for the written request is to prevent an

[[Page 1044]]

interruption of durability mileage accumulation due to test scheduling 
conflicts for weekends, holidays, or other similar circumstances.
    (b) Emission data vehicles and running change vehicles. (1) The 
standard method of mileage accumulation for emission data vehicles and 
running change vehicles is mileage accumulation using either the 
Standard Road Cycle specified in appendix V to this part or the 
Durability Driving Schedule specified in appendix IV to this part.
    (2) The manufacturer may use an alternative mileage accumulation 
method providing the form and extent of the service accumulation 
represents normal driving patterns for that vehicle, the method is 
consistent with good engineering judgment, and the method is described 
in the application for certification.
    (3) Except with the advance approval of the Administrator, all 
vehicles will accumulate mileage at a measured curb weight which is 
within 100 pounds of the estimated curb weight. If the loaded vehicle 
weight is within 100 pounds of being included in the next higher inertia 
weight class as specified in Sec.86.129, the manufacturer may elect to 
conduct the respective emission tests at higher loaded vehicle weight.
    (c) The manufacturer shall determine the mileage at which the 
emission control system and engine combination is stabilized for 
emission-data testing. The manufacturer shall provide to the 
Administrator if requested, a record of the analysis used in making this 
determination. The manufacturer may elect to accumulate 2,000 miles 
(3,219 kilometers) or more on each test vehicle without making a 
determination. The manufacturer must accumulate a minimum of 1,000 miles 
(1,608 kilometers) on each emission data vehicle.
    (d) All test vehicle mileage must be accurately determined, 
recorded, and reported to the Administrator upon request.

Sec.86.1832-01  Optional equipment and air conditioning for test 
vehicles.

    For test vehicles selected under Sec. Sec.86.1822-01 and 86.1828-
01:
    (a)(1) Where it is expected that more than 33 percent of a car line, 
within a test group, will be equipped with an item (whether that item is 
standard equipment or an option), the full estimated weight of that item 
must be included in the curb weight computation for each vehicle 
available with that item in that car line, within that test group.
    (2) Where it is expected that 33 percent or less of the car line, 
within a test group, will be equipped with an item (whether that item is 
standard equipment or an option), no weight for that item will be added 
in computing the curb weight for any vehicle in that car line, within 
that test group, unless that item is standard equipment on the vehicle.
    (3) In the case of mutually exclusive options, only the weight of 
the heavier option will be added in computing the curb weight.
    (4) Optional equipment weighing less than three pounds per item need 
not be considered.
    (b)(1) Where it is expected that more than 33 percent of a car line, 
within a test group, will be equipped with an item (whether that item is 
standard equipment or an option) that can reasonably be expected to 
influence emissions, then such items must actually be installed (unless 
excluded under paragraph (b)(2) of this section) on all emission data 
and durability data vehicles of that car line, within that test group, 
on which the items are intended to be offered in production. Items that 
can reasonably be expected to influence emissions include, but are not 
limited to: air conditioning, power steering, and power brakes.
    (2) If the manufacturer determines by test data or engineering 
evaluation that the actual installation of the optional equipment 
required by paragraph (b)(1) of this section does not affect the 
emissions or fuel economy values, the optional equipment need not be 
installed on the test vehicle.
    (3) The weight of the options must be included in the design curb 
weight and must also be represented in the weight of the test vehicles.
    (4) The engineering evaluation, including any test data, used to 
support the deletion of optional equipment

[[Page 1045]]

from test vehicles, shall be maintained by the manufacturer and be made 
available to the Agency upon request by the Administrator within 15 
business days.
    (c) Except for air conditioning, where it is expected that 33 
percent or less of a car line, within a test group, will be equipped 
with an item (whether that item is standard equipment or an option) that 
can reasonably be expected to influence emissions, that item may not be 
installed on any emission data vehicle or durability data vehicle of 
that car line within that test group, unless that item is standard 
equipment on that vehicle or specifically required by the Administrator.
    (d) Air conditioning must be installed and operational on any 
emission data vehicle of any vehicle configuration that is projected to 
be available with air conditioning regardless of the rate of 
installation of air conditioning within the car line. Paragraphs (a) 
through (c) of this section will be used to determine whether the weight 
of the air conditioner will be included in the equivalent test weight 
calculations for emission testing.



Sec.86.1833-01  Adjustable parameters.

    (a) At the time that emission data vehicles are selected for the 
test fleet, a determination shall be made of those vehicle or engine 
parameters which will be subject to adjustment for certification, 
Selective Enforcement Audit and Production Compliance Audit testing, the 
adequacy of the limits, stops, seals, or other means used to inhibit 
adjustment, and the resulting physically adjustable ranges for each such 
parameter. The manufacturer shall use good engineering judgment in 
making such determinations and shall notify the Administrator of its 
determinations prior to emission data vehicle testing for the affected 
test groups (preferably at an annual preview meeting scheduled before 
the manufacturer begins certification activities for the model year).
    (1) Determining parameters subject to adjustment. (i) The following 
parameters may be subject to adjustment: the idle fuel-air mixture 
parameter on Otto-cycle vehicles; the choke valve action parameter(s) on 
carbureted, Otto-cycle vehicles (or engines); or any parameter on any 
vehicle (Otto-cycle or diesel) which is physically capable of being 
adjusted, may significantly affect emissions, and was not present on the 
manufacturer's vehicles (or engines) in the previous model year in the 
same form and function.
    (ii) Any other parameters on any vehicle or engine which are 
physically capable of being adjusted and which may significantly affect 
emissions may be determined to be subject to adjustment. However, the 
Administrator may do so only if he/she has previously notified the 
manufacturer that he/she might do so and has found, at the time he/she 
gave this notice, that the intervening period would be adequate to 
permit the development and application of the requisite technology, 
giving appropriate consideration to the cost of compliance within such 
period. In no event will this notification be given later than September 
1 of the calendar year two years prior to the model year.
    (iii) In determining the parameters subject to adjustment, the 
following shall be taken into consideration: the likelihood that, for 
each of the parameters listed in paragraphs (e)(1) (i) and (ii) of this 
section, settings other than the manufacturer's recommended setting will 
occur on in-use vehicles (or engines). In determining likelihood, such 
factors may be considered as information contained in the preliminary 
application, surveillance information from similar in-use vehicles, the 
difficulty and cost of gaining access to an adjustment, damage to the 
vehicle if an attempt is made to gain such access and the need to 
replace parts following such attempt, and the effect of settings other 
than the manufacturer's recommended setting on vehicle performance 
characteristics including emission characteristics.
    (2)(i) A parameter may be determined to be adequately inaccessible 
or sealed if:
    (A) In the case of an idle mixture screw, the screw is recessed 
within the carburetor casting and sealed with lead, thermosetting 
plastic, or an inverted elliptical spacer or sheared off after 
adjustment at the factory, and the inaccessibility is such that the

[[Page 1046]]

screw cannot be accessed and/or adjusted with simple tools in one-half 
hour or for $20 (1978 dollars) or less;
    (B) In the case of a choke bimetal spring, the plate covering the 
bimetal spring is riveted or welded in place, or held in place with 
nonreversible screws;
    (C) In the case of a parameter which may be adjusted by elongating 
or bending adjustable members (e.g., the choke vacuum break), the 
elongation of the adjustable member is limited by design or, in the case 
of a bendable member, the member is constructed of a material which when 
bent would return to its original shape after the force is removed 
(plastic or spring steel materials);
    (D) In the case of any parameter, the manufacturer demonstrates that 
adjusting the parameter to settings other than the manufacturer's 
recommended setting takes more than one-half hour or costs more than $20 
(1978 dollars).
    (ii) A physical limit or stop shall be determined to be an adequate 
restraint on adjustability if:
    (A) In the case of a threaded adjustment, the threads are 
terminated, pinned, or crimped so as to prevent additional travel 
without breakage or need for repairs which take more than one-half hour 
or cost more than $20 (1978 dollars);
    (B) The adjustment is ineffective at the end of the limits of travel 
regardless of additional forces or torques applied to the adjustment;
    (C) The manufacturer demonstrates that travel or rotation limits 
cannot be exceeded with the use of simple and inexpensive tools 
(screwdriver, pliers, open-end or box wrenches, etc.) without incurring 
significant and costly damage to the vehicle or control system or 
without taking more than one-half hour or costing more than $20 (1978 
dollars).
    (iii) If manufacturer service manuals or bulletins describe routine 
procedures for gaining access to a parameter or for removing or 
exceeding a physical limit, stop, seal or other means used to inhibit 
adjustment, or if surveillance data indicate that gaining access, 
removing, or exceeding is likely, paragraphs (a)(2)(i) and (ii) of this 
section shall not apply for that parameter.
    (iv) In determining the adequacy of a physical limit, stop, seal, or 
other means used to inhibit adjustment of a parameter not covered by 
paragraph (a)(2)(i) or (ii) of this section, the following shall be 
considered: the likelihood that it will be circumvented, removed, or 
exceeded on in-use vehicles. In determining likelihood, such factors may 
be considered as, but not limited to, information contained in the 
preliminary application; surveillance information from similar in-use 
vehicles; the difficulty and cost of circumventing, removing, or 
exceeding the limit, stop, seal, or other means; damage to the vehicle 
if an attempt is made to circumvent, remove, or exceed it and the need 
to replace parts following such attempt; and the effect of settings 
beyond the limit, stop, seal, or other means on vehicle performance 
characteristics other than emission characteristics.
    (v) In the case of electronic components on circuit boards (such as 
onboard computers) the board is covered with an epoxy resin which 
inhibits the access to components on the board (commonly referred to as 
potting).
    (3) Two physically adjustable ranges shall be determined for each 
parameter subject to adjustment:
    (i)(A) In the case of a parameter determined to be adequately 
inaccessible or sealed, the following may be included within the 
physically adjustable range applicable to testing under this subpart: 
all settings within the production tolerance associated with the nominal 
setting for that parameter, as specified by the manufacturer in the 
application for certification or other information; or
    (B) In the case of other parameters, all settings within physical 
limits or stops determined to be adequate restraints on adjustability 
shall be included within this range. The production tolerances on the 
location of these limits or stops may be included when determining the 
physically adjustable range.
    (ii)(A) In the case of a parameter determined to be adequately 
inaccessible or sealed, only the actual settings to which the parameter 
is adjusted during production shall be included within the physically 
adjustable range applicable

[[Page 1047]]

to testing under subparts G or K (Selective Enforcement Audit and 
Production Compliance Audit) of this part; or
    (B) In the case of other parameters, all settings within physical 
limits or stops determined to be adequate restraints on adjustability, 
as they are actually located on the test vehicle, shall be included 
within the range.
    (b) In lieu of making the determinations required in paragraph (a) 
of this section, the manufacturer may request a determination be made by 
the Administrator prior to emission testing. In that case, all the 
information discussed in paragraph (a) of this section shall be provided 
to the Administrator. The Administrator will respond within 90 days 
(excluding the elapsed time during which additional information 
requested by the Administrator is being gathered by the manufacturer) 
following the receipt of the request for determination.
    (c) If the Administrator determines that the decisions made by the 
manufacturer under the provisions of paragraph (a) of this section were 
not made using good engineering judgment, the Administrator will 
overrule the manufacturers' decisions and conduct testing for 
Certification, Selective Enforcement Audit and/or Production Compliance 
Audit purposes by adjusting parameters according to his/her 
determination of those vehicle or engine parameters subject to 
adjustment, the adequacy of the limits, stops, seals, or other means 
used to inhibit adjustment, and the resulting physically adjustable 
ranges for each such parameter. Furthermore, the Administrator may 
reject testing performed by the manufacturer which failed to follow his/
her determinations.
    (d) Within 30 days following receipt of notification of the 
Administrator's determinations made under paragraph (b) or (c) of this 
section, the manufacturer may request a hearing on the Administrator's 
determinations. The request shall be in writing, signed by an authorized 
representative of the manufacturer, and shall include a statement 
specifying the manufacturer's objections to the Administrator's 
determinations, and data in support of such objections. If, after review 
of the request and supporting data, the Administrator finds that the 
request raises a substantial factual issue, he shall provide the 
manufacturer a hearing in accordance with Sec.86.1853-01 with respect 
to such issue.



Sec.86.1834-01  Allowable maintenance.

    (a) Maintenance performed on vehicles, engines, subsystems, or 
components used to determine exhaust, evaporative or refueling emission 
deterioration factors, as appropriate, is classified as either emission-
related or non-emission-related and each of these can be classified as 
either scheduled or unscheduled. Further, some emission-related 
maintenance is also classified as critical emission-related maintenance.
    (b) This section specifies emission-related scheduled maintenance 
for purposes of obtaining durability data and for inclusion in 
maintenance instructions furnished to purchasers of new motor vehicles 
and under Sec.86.1808-01.
    (1) All emission-related scheduled maintenance for purposes of 
obtaining durability data must occur at the same mileage intervals (or 
equivalent intervals if engines, subsystems, or components are used) 
that will be specified in the manufacturer's maintenance instructions 
furnished to the ultimate purchaser of the motor vehicle or engine under 
Sec.86.1808-01. This maintenance schedule may be updated as necessary 
throughout the testing of the vehicle/engine, provided that no 
maintenance operation is deleted from the maintenance schedule after the 
operation has been performed on the test vehicle or engine.
    (2) Any emission-related maintenance which is performed on vehicles, 
engines, subsystems, or components must be technologically necessary to 
assure in-use compliance with the emission standards. Manufacturers 
shall determine the technological need for maintenance using good 
engineering judgment. The Administrator has determined that emission-
related maintenance at shorter intervals than those outlined in 
paragraphs (b)(3) and (4) of this section is not technologically 
necessary to ensure in-use compliance. However, the Administrator may 
determine that maintenance even more restrictive (e.g., longer 
intervals) than that listed in

[[Page 1048]]

paragraphs (b)(3) and (4) of this section is also not technologically 
necessary.
    (3) Emission-related maintenance in addition to, or at shorter

    (H) Components comprising the selective catalytic reduction system 
(including diesel exhaust fluid tank).
    (I) Any other component whose primary purpose is to reduce emissions 
or whose failure would commonly increase emissions of any regulated

    (ii) All critical emission-related scheduled maintenance must have a 
reasonable likelihood of being performed in-use. The manufacturer shall 
be required to show the reasonable likelihood of such maintenance being 
performed in-use, and such showing shall be made prior to the 
performance of the maintenance on the durability data vehicle. Critical 
emission-related scheduled maintenance items which satisfy one of the 
conditions defined in paragraphs (b)(6)(ii) (A) through (F) of this 
section will be accepted as having a reasonable likelihood of the 
maintenance item being performed in-use, except that DEF replenishment 
must satisfy paragraph (b)(6)(ii)(A) or (b)(6)(ii)(F) of this section to 
be accepted as having a reasonable likelihood of the maintenance item 
being performed in-use.
    (A) Data are presented which establish for the Administrator a 
connection between emissions and vehicle performance such that as 
emissions increase due to lack of maintenance, vehicle performance will 
simultaneously deteriorate to a point unacceptable for typical driving.
    (B) Survey data are submitted which adequately demonstrate to the 
Administrator that, at an 80 percent confidence level, 80 percent of 
such engines already have this critical maintenance item performed in 
use at the recommended interval(s).
    (C) A clearly displayed visible signal system approved by the 
Administrator is installed to alert the vehicle driver that maintenance 
is due. A signal bearing the message ``maintenance needed'' or ``check 
engine,'' or a similar message approved by the Administrator, shall be 
actuated at the appropriate mileage point or by component failure. This 
signal must be continuous while the engine is in operation and not be 
easily eliminated without performance of the required maintenance. 
Resetting the signal shall be a required step in the maintenance 
operation. The method for resetting the signal system shall be approved 
by the Administrator.
    (D) A manufacturer may desire to demonstrate through a survey that a 
critical maintenance item is likely to be performed without a visible 
signal on a maintenance item for which there is no prior in-use 
experience without the signal. To that end, the manufacturer may in a 
given model year market up to 200 randomly selected vehicles per 
critical emission-related maintenance item without such visible signals, 
and monitor the performance of the critical maintenance item by the 
owners to show compliance with paragraph (b)(6)(ii)(B) of this section. 
This option is restricted to two consecutive model years and may not be 
repeated until any previous survey has been completed. If the critical 
maintenance involves more than one test group, the sample will be sales 
weighted to ensure that it is representative of all the groups in 
question.

[[Page 1050]]

    (E) The manufacturer provides the maintenance free of charge, and 
clearly informs the customer that the maintenance is free in the 
instructions provided under Sec.86.1808-01.
    (F) Any other method which the Administrator approves as 
establishing a reasonable likelihood that the critical maintenance will 
be performed in use.
    (iii) Visible signal systems used under paragraph (b)(6)(ii)(C) of 
this section are considered an element of design of the emission control 
system. Therefore, disabling, resetting, or otherwise rendering such 
signals inoperative without also performing the indicated maintenance 
procedure is a prohibited act under section 203(a)(3) of the Clean Air 
Act (42 U.S.C. 7522(a)(3)).
    (7) Changes to scheduled maintenance. (i) For maintenance practices 
that existed prior to the 1980 model year, only the maintenance items 
listed in paragraphs (b)(3) and (4) of this section are currently 
considered by EPA to be emission-related. The Administrator may, 
however, determine additional scheduled maintenance items that existed 
prior to the 1980 model year to be emission-related by announcement in a 
Federal Register Notice. In no event may this notification occur later 
than September 1 of the calendar year two years prior to the affected 
model year.
    (ii) In the case of any new scheduled maintenance, the manufacturer 
must submit a request for approval to the Administrator for any 
maintenance that it wishes to recommend to purchasers and perform during 
durability determination. New scheduled maintenance is that maintenance 
which did not exist prior to the 1980 model year, including that which 
is a direct result of the implementation of new technology not found in 
production prior to the 1980 model year. The manufacturer must also 
include its recommendations as to the category (i.e., emission-related 
or non-emission-related, critical or non-critical) of the subject 
maintenance and, for suggested emission-related maintenance, the maximum 
feasible maintenance interval. Such requests must include detailed 
evidence supporting the need for the maintenance requested, and 
supporting data or other substantiation for the recommended maintenance 
category and for the interval suggested for emission-related 
maintenance. Requests for new scheduled maintenance must be approved 
prior to the introduction of the new maintenance. The Administrator will 
then designate the maintenance as emission-related or non-emission-
related. For maintenance items established as emission-related, the 
Administrator will further designate the maintenance as critical if the 
component which receives the maintenance is a critical component under 
paragraph (b)(6) of this section. For each maintenance item designated 
as emission-related, the Administrator will also establish a 
technologically necessary maintenance interval, based on industry data 
and any other information available to EPA. Designations of emission-
related maintenance items, along with their identification as critical 
or non-critical, and establishment of technologically necessary 
maintenance intervals, will be announced in the Federal Register.
    (iii) Any manufacturer may request a hearing on the Administrator's 
determinations in this paragraph (b)(7). The request shall be in writing 
and shall include a statement specifying the manufacturer's objections 
to the Administrator's determinations, and data in support of such 
objections. If, after review of the request and supporting data, the 
Administrator finds that the request raises a substantial factual issue, 
he shall provide the manufacturer a hearing in accordance with Sec.
86.1853-01 with respect to such issue.
    (c) Non-emission-related scheduled maintenance which is reasonable 
and technologically necessary (e.g., oil change, oil filter change, fuel 
filter change, air filter change, cooling system maintenance, adjustment 
of idle speed, governor, engine bolt torque, valve lash, injector lash, 
timing, adjustment of air pump drive belt tension, lubrication of the 
exhaust manifold heat control valve, lubrication of carburetor choke 
linkage, re-torquing carburetor mounting bolts, etc.) may be performed 
on durability data vehicles at the least frequent intervals recommended 
by the manufacturer to the ultimate purchaser, (e.g., not at the 
intervals recommended for severe service).

[[Page 1051]]

    (d) Unscheduled maintenance on durability data vehicles. (1) 
Unscheduled maintenance may be performed during the testing used to 
determine deterioration factors, except as provided in paragraphs (d)(2) 
and (3) of this section, only under the following provisions defined in 
paragraphs (d)(1) (i) through (iii) of this section:
    (i) A fuel injector or spark plug may be changed if a persistent 
misfire is detected.
    (ii) Readjustment of an Otto-cycle vehicle cold-start enrichment 
system may be performed if there is a problem of stalling.
    (iii) Readjustment of the engine idle speed (curb idle and fast 
idle) may be performed in addition to that performed as scheduled 
maintenance under paragraph (c) of this section if the idle speed 
exceeds the manufacturer's recommended idle speed by 300 rpm or more, or 
if there is a problem of stalling.
    (2) Any other unscheduled vehicle, emission control system, or fuel 
system adjustment, repair, removal, disassembly, cleaning, or 
replacement during testing to determine deterioration factors shall be 
performed (using good engineering judgment) only in the following 
circumstances:
    (i) The part failure or system malfunction, or the repair of such 
failure or malfunction, does not render the vehicle or engine 
unrepresentative of vehicles or engines in use and does not require 
direct access to the combustion chamber, except for spark plug, fuel 
injection component, or removable prechamber removal or replacement.
    (ii) The need for maintenance or repairs is indicated by an overt 
indication of malfunction such as persistent misfiring, engine stalling, 
overheating, fluid leakage, loss of oil pressure, excessive fuel 
consumption, or excessive power loss. The Administrator shall be given 
the opportunity to verify the existence of an overt indication of part 
failure and/or vehicle/engine malfunction (e.g., misfiring, stalling, 
black smoke), or an activation of an audible and/or visible signal, 
prior to the performance of any maintenance to which such overt 
indication or signal is relevant under the provisions of this section.
    (iii) The OBD system of a durability data vehicle representing any 
test group certifying fully to the Federal OBD requirements as specified 
in Sec.86.1806-01(a) through (h) has specifically detected the problem 
and has illuminated the malfunction indicator light.
    (3) Emission measurement may not be used as a means of determining 
the need for unscheduled maintenance under paragraph (d)(2) of this 
section, except under the following conditions:
    (i) The Administrator may approve unscheduled maintenance on 
durability data vehicles based upon a significant change in emission 
levels that indicates a vehicle or engine malfunction. In these cases 
the Administrator may first approve specific diagnostic procedures to 
identify the source of the problem. The Administrator may further 
approve of specific corrections to the problem after the problem has 
been identified. The Administrator may only approve the corrective 
action after it is determined that:
    (A) The malfunction was caused by nonproduction build practices or 
by a previously undetected design problem;
    (B) The malfunction will not occur in production vehicles or engines 
in use; and
    (C) The deterioration factor generated by the durability data 
vehicle or engine will remain unaffected by the malfunction or by the 
corrective action (e.g., the malfunction was present for only a short 
period of time before detection, replacement parts are functionally 
representative of the proper mileage or hours, etc.).
    (ii) Following any unscheduled maintenance approved under paragraph 
(d)(3)(i) of this section, the manufacturer shall perform an after-
maintenance emission test. If the Administrator determines that the 
after-maintenance emission levels for any pollutant indicates that the 
deterioration factor is no longer representative of production, the 
Administrator may disqualify the durability data vehicle or engine.
    (4) If a part failure or system malfunction occurrence and/or repair 
has

[[Page 1052]]

rendered the vehicle/engine unrepresentative of vehicles in use, the 
vehicle/engine shall not be used for determining deterioration factors.
    (5) Repairs to vehicle components of a durability data vehicle other 
than the engine, emission control system, or fuel system, shall be 
performed only as a result of part failure, vehicle system malfunction, 
or with the advance approval of the Administrator.
    (e) Maintenance on emission data vehicles and engines. (1) 
Adjustment of engine idle speed on emission data vehicles may be 
performed once before the low-mileage/low-hour emission test point. Any 
other engine, emission control system, or fuel system adjustment, 
repair, removal, disassembly, cleaning, or replacement on emission data 
vehicles shall be performed only with the advance approval of the 
Administrator.
    (2) Repairs to vehicle components of an emission data vehicle other 
than the engine, emission control system, or fuel system, shall be 
performed only as a result of part failure, vehicle system malfunction, 
or with the advance approval of the Administrator.
    (f) Equipment, instruments, or tools may not be used to identify 
malfunctioning, maladjusted, or defective engine components unless the 
same or equivalent equipment, instruments, or tools will be available to 
dealerships and other service outlets and:
    (1) Are used in conjunction with scheduled maintenance on such 
components; or
    (2) Are used subsequent to the identification of a vehicle or engine 
malfunction, as provided in paragraph (d)(2) of this section for 
durability data vehicles or in paragraph (e)(1) of this section for 
emission data vehicles; or
    (3) Unless specifically authorized by the Administrator.
    (g) Complete emission tests (see Sec. Sec.86.106-96 through 
86.145-82) are required, unless waived by the Administrator, before and 
after scheduled maintenance approved for durability data vehicles. The 
manufacturer may perform emission tests before unscheduled maintenance. 
Complete emission tests are required after unscheduled maintenance which 
may reasonably be expected to affect emissions. The Administrator may 
waive the requirement to test after unscheduled maintenance. These test 
data may be submitted weekly to the Administrator, but shall be air 
posted or delivered within 7 days after completion of the tests, along 
with a complete record of all pertinent maintenance, including a 
preliminary engineering report of any malfunction diagnosis and the 
corrective action taken. A complete engineering report shall be 
delivered to the Administrator concurrently with the manufacturer's 
application for certification.
    (h) When air conditioning SFTP exhaust emission tests are required, 
the manufacturer must document that the vehicle's air conditioning 
system is operating properly and in a representative condition. Required 
air conditioning system maintenance is performed as unscheduled 
maintenance and does not require the Administrator's approval.

Sec.86.1835-01  Confirmatory certification testing.

    (a) Testing by the Administrator. (1) The Administrator may require 
that any one or more of the test vehicles be submitted to the Agency, at 
such place or places as the Agency may designate, for the purposes of 
conducting emissions tests. The Administrator may specify that such 
testing be conducted at the manufacturer's facility, in which case 
instrumentation and equipment specified by the Administrator shall be 
made available by the manufacturer for test operations. Any testing 
conducted at a manufacturer's facility pursuant to this paragraph shall 
be scheduled by the manufacturer as promptly as possible.
    (i) The Administrator may adjust or cause to be adjusted any 
adjustable parameter of an emission-data vehicle which the Administrator 
has determined to be subject to adjustment for certification testing in 
accordance with Sec.86.1833-01(a)(1), to any setting within the 
physically adjustable range of that parameter, as determined by the 
Administrator in accordance with Sec.86.1833-01(a)(3), prior to the 
performance of any tests to determine whether

[[Page 1053]]

such vehicle or engine conforms to applicable emission standards, 
including tests performed by the manufacturer under Sec.86.1829-01(b). 
However, if the idle speed parameter is one which the Administrator has 
determined to be subject to adjustment, the Administrator shall not 
adjust it to a setting which causes a higher engine idle speed than 
would have been possible within the physically adjustable range of the 
idle speed parameter on the engine before it accumulated any dynamometer 
service, all other parameters being identically adjusted for the purpose 
of the comparison. The Administrator, in making or specifying such 
adjustments, will consider the effect of the deviation from the 
manufacturer's recommended setting on emissions performance 
characteristics as well as the likelihood that similar settings will 
occur on in-use light-duty vehicles, light-duty trucks, or complete 
heavy-duty vehicles. In determining likelihood, the Administrator will 
consider factors such as, but not limited to, the effect of the 
adjustment on vehicle performance characteristics and surveillance 
information from similar in-use vehicles.
    (ii) For those vehicles parameters which the Administrator has not 
determined to be subject to adjustment during testing in accordance with 
Sec.86.1833-01(a)(1), the vehicle presented to the Administrator for 
testing shall be calibrated within the production tolerances applicable 
to the manufacturer's specifications to be shown on the vehicle label 
(see Sec.86.1807-01) as specified in the application for 
certification. If the Administrator determines that a vehicle is not 
within such tolerances, the vehicle will be adjusted, at the facility 
designated by the Administrator, prior to the test and an engineering 
report shall be submitted to the Administrator describing the corrective 
action taken. Based on the engineering report, the Administrator will 
determine if the vehicle will be used as an emission data vehicle.
    (2) If the Administrator determines that the test data developed on 
an emission data vehicle under paragraph (a)(1) of this section would 
cause that vehicle to fail under the provisions of Sec.86.1841-01, 
then the following procedure shall be observed:
    (i) The manufacturer may request a retest. Before the retest, those 
vehicle or engine parameters which the Administrator has not determined 
to be subject to adjustment for certification testing in accordance with 
Sec.86.1833-01(a)(1) may be readjusted to manufacturer's 
specification, if these adjustments were made incorrectly prior to the 
first test. The Administrator may adjust or cause to be adjusted any 
parameter which the Administrator has determined to be subject to 
adjustment to any setting within the physically adjustable range of that 
parameter, as determined by the Administrator in accordance with Sec.
86.1833-01(a)(3). Other maintenance or repairs may be performed in 
accordance with Sec.86.1834-01. All work on the vehicle shall be done 
at such location and under such conditions as the Administrator may 
prescribe.
    (ii) The vehicle will be retested by the Administrator and the 
results of this test shall comprise the official data for the emission-
data vehicle.
    (3) If sufficient durability data are not available at the time of 
any emission test conducted under paragraph (a)(1) of this section to 
enable the Administrator to determine whether an emission-data vehicle 
would fail, the manufacturer may request a retest in accordance with the 
provisions of paragraph (a)(2) of this section. If the manufacturer does 
not promptly make such request, he shall be deemed to have waived the 
right to a retest. A request for retest must be made before the 
manufacturer removes the vehicle from the test premises.
    (4) Retesting for fuel economy reasons or for compliance with 
greenhouse gas exhaust emission standards in Sec.86.181-12 may be 
conducted under the provisions of Sec.600.008-08 of this chapter.
    (b) Manufacturer-conducted confirmatory testing. (1) If the 
Administrator determines not to conduct a confirmatory test under the 
provisions of paragraph (a) of this section, manufacturers of light-duty 
vehicles, light-duty trucks, and/or medium-duty passenger vehicles will 
conduct a confirmatory test at their facility after submitting

[[Page 1054]]

the original test data to the Administrator whenever any of the 
conditions listed in paragraphs (b)(1)(i) through (vi) of this section 
exist, and complete heavy-duty vehicles manufacturers will conduct a 
confirmatory test at their facility after submitting the original test 
data to the Administrator whenever the conditions listed in paragraph 
(b)(1)(i) or (b)(1)(ii) of this section exist, as follows:
    (i) The vehicle configuration has previously failed an emission 
standard;
    (ii) The test exhibits high emission levels determined by exceeding 
a percentage of the standards specified by the Administrator for that 
model year;
    (iii) The fuel economy value of the test as measured in accordance 
with the procedures in 40 CFR part 600 is higher than expected based on 
procedures approved by the Administrator;
    (iv) The fuel economy value as measured in accordance with the 
procedures in part 600 of this title, is close to a Gas Guzzler Tax 
threshold value based on tolerances established by the Administrator for 
that model year; or
    (v) The fuel economy value as measured in accordance with the 
procedures in part 600 of this title, is a potential fuel economy leader 
for a class of vehicles based on Administrator provided cut points for 
that model year.
    (vi) The exhaust carbon-related exhaust emissions of the test as 
measured in accordance with the procedures in 40 CFR part 600 are lower 
than expected based on procedures approved by the Administrator.
    (2) If the Administrator selects the vehicle for confirmatory 
testing based on the manufacturer's original test results, the testing 
shall be conducted as ordered by the Administrator. In this case, the 
manufacturer-conducted confirmatory testing specified under paragraph 
(b)(1) of this section would not be required.
    (3) For light-duty vehicles, light-duty trucks, and medium-duty 
passenger vehicles the manufacturer shall conduct a retest of the FTP or 
highway test if the difference between the fuel economy of the 
confirmatory test and the original manufacturer's test equals or exceeds 
three percent (or such lower percentage to be applied consistently to 
all manufacturer conducted confirmatory testing as requested by the 
manufacturer and approved by the Administrator).
    (i) For use in the fuel economy and exhaust greenhouse gas fleet 
averaging program described in 40 CFR parts 86 and 600, the manufacturer 
may, in lieu of conducting a retest, accept as official the lower of the 
original and confirmatory test fuel economy results, and by doing so 
will also accept as official the calculated CREE value associated with 
the lower fuel economy test results.
    (ii) The manufacturer shall conduct a second retest of the FTP or 
highway test if the fuel economy difference between the second 
confirmatory test and the original manufacturer test equals or exceeds 
three percent (or such lower percentage as requested by the manufacturer 
and approved by the Administrator) and the fuel economy difference 
between the second confirmatory test and the first confirmatory test 
equals or exceeds three percent (or such lower percentage as requested 
by the manufacturer and approved by the Administrator). In lieu of 
conducting a second retest, the manufacturer may accept as official (for 
use in the fuel economy program and the exhaust greenhouse gas fleet 
averaging program) the lowest fuel economy of the original test, the 
first confirmatory test, and the second confirmatory test fuel economy 
results, and by doing so will also accept as official the calculated 
CREE value associated with the lowest fuel economy test results.
    (c) Official test determination. (1) Whenever the Administrator or 
the manufacturer conducts a confirmatory test segment on a test vehicle, 
the results of that test segment, unless subsequently invalidated by the 
Administrator, shall comprise the official data for that test segment 
for the vehicle at the prescribed test point and the manufacturer's 
original test data for that test segment for that prescribed test point 
shall not be used in determining compliance with emission standards.

[[Page 1055]]

    (i) If the Administrator or the manufacturer conducts more than one 
passing, valid, confirmatory test, the results from the first passing, 
valid confirmatory test shall be considered official and used in 
determining compliance with emission standards.
    (ii) Official test results for fuel economy and exhaust 
CO2 emission purposes are determined in accordance with the 
provisions of Sec.600.008-08 of this chapter.
    (iii) The Administrator may stop a test after any evaporative test 
segment and use as official data any valid results obtained up to that 
point in the test, as described in subpart B of this part.
    (2) Whenever the Administrator or the manufacturer does not conduct 
a confirmatory test on a test vehicle at a test point, the 
manufacturer's original test data will be accepted as the official data 
for that point.
    (i) If the Administrator makes a determination based on testing 
under paragraph (a) of this section (or other appropriate correlation 
test data), that there is a lack of correlation between the 
manufacturer's test equipment or procedures and the test equipment or 
procedures used by the Administrator, no manufacturer's test data will 
be accepted for purposes of certification until the reasons for the lack 
of correlation are determined and the validity of the data is 
established by the manufacturer.
    (ii) If the Administrator has reasonable basis to believe that any 
test data submitted by the manufacturer is not accurate or has been 
obtained in violation of any provisions of this subpart, the 
Administrator may refuse to accept that data as the official data 
pending retesting or submission of further information.
    (iii) If the manufacturer conducts more than one test on an emission 
data vehicle in the same configuration (excluding confirmatory tests run 
under paragraph (b) of this section), the data from the last test in 
that series of tests on that vehicle, will constitute the official data.
    (d) Upon request of the manufacturer, the Administrator may issue a 
conditional certificate of conformity for a test group which has not 
completed the Administrator testing required under paragraph (a) of this 
section. Such a certificate will be issued based upon the condition that 
the confirmatory testing be completed in an expedited manner and that 
the results of the testing be in compliance with all standards and 
procedures.
    (1) If, based on this testing or any other information, the 
Administrator later determines that the vehicles included in this test 
group do not meet the applicable standards, the Administrator will 
notify the manufacturer that the certificate is suspended. The 
certificate may be suspended in whole or in part as determined by the 
Administrator. Upon such a notification, the manufacturer must 
immediately cease the introduction of the affected vehicles into 
commerce. The manufacturer may request a hearing to appeal the 
Administrators decision using the provisions of Sec.86.1853-01.
    (2) Production of vehicles by a manufacturer under the terms of this 
paragraph (d) will be deemed to be a consent to recall all vehicles in 
the test group which the Administrator determines do not meet applicable 
standards, and to cause such nonconformity to be remedied at no expense 
to the owner.

Sec.86.1836-01  Manufacturer-supplied production vehicles for 
testing.

    Any manufacturer obtaining certification under this subpart shall 
supply to the Administrator, upon request, a reasonable number of 
production vehicles selected by the Administrator which are 
representative of the engines, emission control systems, fuel systems, 
and transmission offered and typical of production models available for 
sale under the certificate. These vehicles shall be supplied for testing 
at such time and place and for such reasonable periods as the 
Administrator may require.



Sec.86.1837-01  Rounding of emission measurements.

    (a) Unless otherwise specified, the results of all emission tests 
shall be rounded to the number of places to the

[[Page 1056]]

right of the decimal point indicated by expressing the applicable 
emission standard of this subpart to one additional significant figure, 
in accordance with 40 CFR 1065.20.
    (b) Fleet average NOX value calculations, where 
applicable, must be rounded before comparing with the applicable fleet 
average standard and calculating credits generated or needed as follows: 
manufacturers must round to the same number of significant figures that 
are contained in the quantity of vehicles in the denominator of the 
equation used to compute the fleet average NOX emissions, but 
to no less than one more decimal place than that of the applicable fleet 
average standard.

Sec.86.1838-01  Small-volume manufacturer certification procedures.

    (a) Overview. The small-volume manufacturer certification procedures 
described in paragraphs (b) and (c) of this section are optional. Small-
volume manufacturers may use these optional procedures to demonstrate 
compliance with the general standards and specific emission requirements 
contained in this subpart.
    (b) Eligibility requirements--(1) Small-volume manufacturers. (i) 
Optional small-volume manufacturer certification procedures apply for 
vehicles produced by manufacturers with the following number of combined 
sales of vehicles subject to standards under this subpart in all states 
and territories of the United States in the model year for which 
certification is sought, including all vehicles and engines imported 
under the provisions of 40 CFR 85.1505 and 85.1509:
    (A) 5,000 units for the Tier 3 standards described in Sec. Sec.
86.1811, 86.1813, and 86.1816. This volume threshold applies for phasing 
in the Tier 3 standards and for determining the corresponding 
deterioration factors. This is based on average nationwide sales volumes 
for model years 2012 through 2014 for manufacturers that sell vehicles 
in model year 2012. The provision allowing delayed compliance with the 
Tier 3 standards applies for qualifying companies even if sales after 
model year 2014 increase beyond 5,000 units. Manufacturers with no sales 
in model year 2012 may instead rely on projected sales volumes; however, 
if nationwide sales exceed an average value of 5,000 units in any three 
consecutive model years, the manufacturer is no longer eligible for 
provisions that apply to small-volume manufacturers after two additional 
model years. For example, if actual sales in model years 2015 through 
2017 exceed 5,000 units, the small-volume provisions would no longer 
apply starting in model year 2020.
    (B) No small-volume sales threshold applies for the heavy-duty 
greenhouse gas standards; alternative small-volume criteria apply as 
described in Sec.86.1819-14(k)(5).
    (C) 15,000 units for all other requirements. See Sec.86.1845 for 
separate provisions that apply for in-use testing.
    (ii) If a manufacturer's aggregated sales in the United States, as 
determined in paragraph (b)(3) of this section are fewer than the number 
of units specified in paragraph (b)(1)(i) of this section, the 
manufacturer (or each manufacturer in the case of manufacturers in an 
aggregated relationship) may certify under the provisions of paragraph 
(c) of this section.
    (iii) A manufacturer that qualifies as a small business under the 
Small Business Administration regulations in 13 CFR Part 121 is eligible 
for all the provisions that apply for small-volume manufacturers under 
this subpart. See Sec.86.1801-12(j) to determine whether companies 
qualify as small businesses.
    (iv) The sales volumes specified in this section are based on actual 
sales, unless otherwise specified.
    (v) Except for delayed implementation of new emission standards, an 
eligible manufacturer must transition out of the special provisions that 
apply for small-volume manufacturers as described in Sec.86.1801-
12(k)(2)(i) through (iii) if sales volumes increase above the applicable 
threshold.
    (2) Small-volume test groups. (i) If the aggregated sales in all 
states and territories of the United States, as determined in paragraph 
(b)(3) of this section are equal to or greater than 15,000 units, then 
the manufacturer (or each

[[Page 1057]]

manufacturer in the case of manufacturers in an aggregated relationship) 
will be allowed to certify a number of units under the small-volume test 
group certification procedures in accordance with the criteria 
identified in paragraphs (b)(2)(ii) through (iv) of this section.
    (ii) If there are no additional manufacturers in an aggregated 
relationship meeting the provisions of paragraph (b)(3) of this section, 
then the manufacturer may certify whole test groups whose total 
aggregated sales (including heavy-duty engines) are less than 15,000 
units using the small-volume provisions of paragraph (c) of this 
section.
    (iii) If there is an aggregated relationship with another 
manufacturer which satisfies the provisions of paragraph (b)(3) of this 
section, then the following provisions shall apply:
    (A) If none of the manufacturers own 50 percent or more of another 
manufacturer in the aggregated relationship, then each manufacturer may 
certify whole test groups whose total aggregated sales (including heavy-
duty engines) are less than 15,000 units using the small-volume 
provisions of paragraph (c) of this section.
    (B) If any of the manufacturers own 50 percent or more of another 
manufacturer in the aggregated relationship, then the limit of 14,999 
units must be shared among the manufacturers in such a relationship. In 
total for all the manufacturers involved in such a relationship, 
aggregated sales (including heavy-duty engines) of up to 14,999 units 
may be certified using the small-volume provisions of paragraph (c) of 
this section. Only whole test groups shall be eligible for small-volume 
status under paragraph (c) of this section.
    (iv) In the case of a joint venture arrangement (50/50 ownership) 
between two manufacturers, each manufacturer retains its eligibility for 
14,999 units under the small-volume test group certification procedures, 
but the joint venture must draw its maximum 14,999 units from the units 
allocated to its parent manufacturers. Only whole test groups shall be 
eligible for small-volume status under paragraph (c) of this section.
    (3) Sales aggregation for related manufacturers. The projected or 
actual sales from different firms shall be aggregated in the following 
situations:
    (i) Vehicles and/or engines produced by two or more firms, one of 
which is 10 percent or greater part owned by another;
    (ii) Vehicles and/or engines produced by any two or more firms if a 
third party has equity ownership of 10 percent or more in each of the 
firms;
    (iii) Vehicles and/or engines produced by two or more firms having a 
common corporate officer(s) who is (are) responsible for the overall 
direction of the companies;
    (iv) Vehicles and/or engines imported or distributed by all firms 
where the vehicles and/or engines are manufactured by the same entity 
and the importer or distributor is an authorized agent of the entity.
    (c) Small-volume provisions. Small-volume manufacturers and small-
volume test groups shall demonstrate compliance with all applicable 
sections of this subpart, with the following exceptions:
    (1) Durability demonstration. Use the provisions of Sec.86.1826 
rather than the requirements of Sec. Sec.86.1823, 86.1824, and 
86.1825.
    (2) In-use verification testing. Measure emissions from in-use 
vehicles as described in Sec.86.1845, subject to the following 
additional provisions:
    (i) In-use verification test vehicles may be procured from customers 
or may be owned by, or under the control of the manufacturer, provided 
that the vehicle has accumulated mileage in typical operation on public 
streets and has received typical maintenance.
    (ii) In lieu of procuring in-use verification test vehicles that 
have a minimum odometer reading of 50,000 miles, a manufacturer may 
demonstrate to the satisfaction of the Agency that, based on owner 
survey data, the average mileage accumulated after 4 years for a given 
test group is less than 50,000 miles. The Agency may approve procurement 
of in-use verification test vehicles that have a lower minimum odometer 
reading based on such data.
    (iii) The provisions of Sec.86.1845-04(c)(2) that require one 
vehicle of each test group during high mileage in-use verification 
testing to have a minimum odometer mileage do not apply.

[[Page 1058]]

    (iv) Manufacturers intending to use the provisions of this paragraph 
(c) shall submit to the Agency a plan detailing how these provisions 
will be met before submitting an application for certification for the 
subject vehicles.
    (d) Operationally independent manufacturers. Manufacturers may 
submit an application to EPA requesting treatment as an operationally 
independent manufacturer. A manufacturer that is granted operationally 
independent status may qualify for all the regulatory provisions of this 
subpart that apply for small-volume manufacturers on the basis of its 
own vehicle production and/or sales volumes, and would not require 
aggregation with related manufacturers. In this paragraph (d), the term 
``related manufacturer(s)'' means manufacturers that would qualify for 
aggregation under the requirements of paragraph (b)(3) of this section.
    (1) To request consideration for operationally independent status, 
the manufacturer must submit an application demonstrating that the 
following criteria are met, and have been continuously met for at least 
two years prior to submitting the application to EPA. The application 
must be signed by the president or the chief executive officer of the 
manufacturer.
    (i) The applicant does not receive any financial or other means of 
support of economic value from any related manufacturers for purposes of 
vehicle design, vehicle parts procurement, research and development, and 
production facilities and operation. Any transactions with related 
manufacturers must be conducted under normal commercial arrangements 
like those conducted with other external parties. Any such transactions 
with related manufacturers shall be demonstrated to have been at 
competitive pricing rates to the applicant.
    (ii) The applicant maintains wholly separate and independent 
research and development, testing, and vehicle manufacturing and 
production facilities.
    (iii) The applicant does not use any vehicle engines, powertrains, 
or platforms developed or produced by related manufacturers.
    (iv) The applicant does not hold any patents jointly with related 
manufacturers.
    (v) The applicant maintains separate business administration, legal, 
purchasing, sales, and marketing departments as well as wholly 
autonomous decision making on all commercial matters.
    (vi) The Board of Directors of the applicant may not share more than 
25 percent of its membership with any related manufacturer. No top 
operational management of the applicant may be shared with any related 
manufacturer, including the president, the chief executive officer 
(CEO), the chief financial officer (CFO), and the chief operating 
officer (COO). No individual director or combination of directors that 
is shared with a related manufacturer may exercise exclusive management 
control over either or both companies.
    (vii) Parts or components supply agreements between the applicant 
and related companies must be established through open market processes. 
An applicant that sells or otherwise provides parts and/or vehicle 
components to a manufacturer that is not a related manufacturer must do 
so through the open market at competitive pricing rates.
    (2) Manufacturers that have been granted operationally independent 
status must report any material changes to the information provided in 
the application within 60 days of the occurrence of the change. If such 
a change occurs that results in the manufacturer no longer meeting the 
requirements of the application, the manufacturer will lose the 
eligibility to be considered operationally independent. The EPA will 
confirm that the manufacturer no longer meets one or more of the 
criteria and thus is no longer considered operationally independent, and 
will notify the manufacturer of the change in status. A manufacturer who 
loses the eligibility for operationally independent status must 
transition to the appropriate emission standards no later than the third 
model year after the model year in which the loss of eligibility 
occurred. For example, a manufacturer that loses eligibility in their 
2018 model year would be required to meet appropriate standards in the 
2021

[[Page 1059]]

model year. A manufacturer that loses eligibility must meet the 
applicable criteria for three consecutive model years before they are 
allowed to apply for a reinstatement of their operationally independent 
status.
    (3) The manufacturer applying for operational independence shall 
engage an independent certified public accountant, or firm of such 
accountants (hereinafter referred to as ``CPA''), to perform an agreed-
upon procedures attestation engagement of the underlying documentation 
that forms the basis of the application as required in this paragraph 
(d).
    (i) The CPA shall perform the attestation engagements in accordance 
with the Statements on Standards for Attestation Engagements established 
by the American Institute of Certified Public Accountants.
    (ii) The CPA may complete the requirements of this paragraph with 
the assistance of internal auditors who are employees or agents of the 
applicant, so long as such assistance is in accordance with the 
Statements on Standards for Attestation Engagements established by the 
American Institute of Certified Public Accountants.
    (iii) Notwithstanding the requirements of paragraph (d)(3)(ii) of 
this section, an applicant may satisfy the requirements of this 
paragraph (d)(3) if the requirements of this paragraph (d)(3) are 
completed by an auditor who is an employee of the applicant, provided 
that such employee:
    (A) Is an internal auditor certified by the Institute of Internal 
Auditors, Inc. (hereinafter referred to as ``CIA''); and
    (B) Completes the internal audits in accordance with the standards 
for internal auditing established by the Institute of Internal Auditors.
    (iv) Use of a CPA or CIA who is debarred, suspended, or proposed for 
debarment pursuant to the Governmentwide Debarment and Suspension 
Regulations, 2 CFR part 1532, or the Debarment, Suspension, and 
Ineligibility Provisions of the Federal Acquisition Regulations, 48 CFR 
part 9, subpart 9.4, shall be deemed in noncompliance with the 
requirements of this section.

    Effective Date Note: At 86 FR 34371, June 29, 2021, Sec.86.1838-01 
was amended, effective July 29, 2021.



Sec.86.1839-01  Carryover of certification data.

    (a) In lieu of testing an emission-data or durability vehicle 
selected under Sec.86.1822-01, Sec.86.1828-01, or Sec.86.1829-01, 
and submitting data therefrom, a manufacturer may submit exhaust 
emission data, evaporative emission data and/or refueling emission data, 
as applicable, on a similar vehicle for which certification has been 
obtained or for which all applicable data required under Sec.86.1845-
01 has previously been submitted. To be eligible for this provision, the 
manufacturer must use good engineering judgment and meet the following 
criteria:
    (1) In the case of durability data, the manufacturer must determine 
that the previously generated durability data represent a worst case or 
equivalent rate of deterioration for all applicable emission 
constituents compared to the configuration selected for durability 
demonstration.
    (i) Prior to certification, the Administrator may require the 
manufacturer to provide data showing that the distribution of catalyst 
temperatures of the selected durability configuration is effectively 
equivalent or lower than the distribution of catalyst temperatures of 
the vehicle configuration which is the source of the previously 
generated data.
    (ii) For the 2001, 2002, and 2003 model years only, paragraph (a)(1) 
of this section does not apply to the use of exhaust emission 
deterioration factors meeting the requirements of Sec.86.1823-
01(c)(2).
    (2) In the case of emission data, the manufacturer must determine 
that the previously generated emissions data represent a worst case or 
equivalent level of emissions for all applicable emission constituents 
compared to the

[[Page 1060]]

configuration selected for emission compliance demonstration.
    (b) In lieu of using newly aged hardware on an EDV as allowed under 
the provisions of Sec.86.1823-08(f)(2), a manufacturer may use similar 
hardware aged for an EDV previously submitted, provided that the 
manufacturer determines that the previously aged hardware represents a 
worst case or equivalent rate of deterioration for all applicable 
emission constituents for durability demonstration.

[64 FR 23925, May 4, 1999, as amended at 71 FR 2836, Jan. 17, 2006]



Sec.86.1840-01  Special test procedures.

    (a) The Administrator may, on the basis of written application by a 
manufacturer, prescribe test procedures, other than those set forth in 
this part, for any light-duty vehicle, light-duty truck, or complete 
heavy-duty vehicle which the Administrator determines is not susceptible 
to satisfactory testing by the procedures set forth in this part.
    (b) If the manufacturer does not submit a written application for 
use of special test procedures but the Administrator determines that a 
light-duty vehicle, light-duty truck, or complete heavy-duty vehicle is 
not susceptible to satisfactory testing by the procedures set forth in 
this part, the Administrator shall notify the manufacturer in writing 
and set forth the reasons for such rejection in accordance with the 
provisions of Sec.86.1848(a)(2).
    (c) Manufacturers of vehicles equipped with periodically 
regenerating aftertreatment devices must propose a procedure for testing 
and certifying such vehicles, including SFTP testing, for the review and 
approval of the Administrator. The manufacturer must submit its proposal 
before it begins any service accumulation or emission testing. The 
manufacturer must provide with its submittal sufficient documentation 
and data for the Administrator to fully evaluate the operation of the 
aftertreatment devices and the proposed certification and testing 
procedure.
    (d) The provisions of paragraph (a) and (b) of this section also 
apply to MDPVs.

[65 FR 59976, Oct. 6, 2000, as amended at 71 FR 51488, Aug. 30, 2006; 77 
FR 34146, June 8, 2012]



Sec.86.1841-01  Compliance with emission standards for the purpose
of certification.

    (a) Certification levels of a test vehicle will be calculated for 
each emission constituent applicable to the test group for both full and 
intermediate useful life as appropriate.
    (1) If the durability demonstration procedure used by the 
manufacturer under the provisions of Sec.86.1823, Sec.86.1824, or 
Sec.86.1825 requires a DF to be calculated, the DF shall be applied to 
the official test results determined in Sec.86.1835-01(c) for each 
regulated emission constituent and for full and intermediate useful 
life, as appropriate, using the following procedures:
    (i) For additive DF's, the DF will be added to the emission result. 
The sum will be rounded to the same level of precision as the standard 
for the constituent at full and/or intermediate useful life, as 
appropriate. This rounded sum is the certification level for that 
emission constituent and for that useful life mileage.
    (ii) For multiplicative DFs, the DF will be multiplied by the 
emission result for each regulated constituent. The product will be 
rounded to the same level of precision as the standard for the 
constituent at full and intermediate useful life, as appropriate. This 
rounded product is the certification level for that emission constituent 
and for that useful life mileage.
    (iii) For the SFTP composite standard of NMHC + NOX, the 
measured results of NMHC and NOX must each be adjusted by 
their corresponding deterioration factors before the composite NMHC + 
NOX certification level is calculated. Where the applicable 
FTP exhaust hydrocarbon emission standard is an NMOG standard, the 
applicable NMOG deterioration factor must be used in place of the NMHC 
deterioration factor, unless otherwise approved by the Administrator.
    (2) If the durability demonstration procedure used by the 
manufacturer

[[Page 1061]]

under the provisions of Sec.86.1823, Sec.86.1824, or Sec.86.1825, 
as applicable, requires testing of the EDV with aged emission 
components, the official results of that testing determined under the 
provisions of Sec.86.1835-01(c) shall be rounded to the same level of 
precision as the standard for each regulated constituent at full and 
intermediate useful life, as appropriate. This rounded emission value is 
the certification level for that emission constituent at that useful 
life mileage.
    (3) Compliance with full useful life CO2 exhaust emission 
standards shall be demonstrated at certification by the certification 
levels on the FTP and HFET tests for carbon-related exhaust emissions 
determined according to Sec.600.113 of this chapter.
    (4) The rounding required in paragraph (a) of this section shall be 
conducted in accordance with the provisions of Sec.86.1837-01.
    (b) To be considered in compliance with the standards for the 
purposes of certification, the certification levels for the test vehicle 
calculated in paragraph (a) of this section shall be less than or equal 
to the standards for all emission constituents to which the test group 
is subject, at both full and intermediate useful life as appropriate for 
that test group.
    (c) Every test vehicle of a test group must comply with all 
applicable exhaust emission standards before that test group may be 
certified.
    (d) Every test vehicle of an evaporative/refueling family must 
comply with all applicable evaporative and/or refueling emission 
standards before that family may be certified.
    (e) Unless otherwise approved by the Administrator, manufacturers 
must not use Reactivity Adjustment Factors (RAFs) in their calculation 
of the certification level of any pollutant for any vehicle except for 
LDVs and LLDTs participating in the National Low Emission Vehicle (NLEV) 
program described in subpart R of this part, regardless of the fuel used 
in the test vehicle.

Sec.86.1842-01  Addition of a vehicle after certification; and changes
to a vehicle covered by certification.

    (a) Addition of a car line after certification. (1) If a 
manufacturer proposes to add to its product line a new car line of the 
same test group as vehicles previously certified but which was not 
described in the application for certification when the test vehicle(s) 
representing other vehicles of that combination was certified, it shall 
notify the Administrator. This notification shall include a full 
description of the vehicle to be added.
    (2) The manufacturer shall perform such tests on the test vehicle(s) 
representing the vehicle to be added which would have been required if 
the vehicle had been included in the original application for 
certification.
    (3) If, after a review of the test reports and data submitted by the 
manufacturer, and data derived from any testing conducted under Sec.
86.1835-01, the Administrator determines that the test vehicle(s) or 
test engine(s) meets all applicable standards, the appropriate 
certificate will be amended accordingly. If the Administrator determines 
that the test vehicle(s) does not meet applicable standards, she/he will 
proceed under Sec.86.1850-01.
    (b) Changes to the configuration of vehicles covered by a 
Certificate of Conformity. (1) A manufacturer will notify the 
Administrator concurrently with (or in advance of) any change or 
addition in production vehicles which creates a new vehicle 
configuration within the car lines covered in a certified test group, 
giving a full description of the change. Such a change is referred to as 
a running change. Upon notification, the manufacturer may begin 
production of the running change if the manufacturer determines that 
following the change all affected vehicles will still meet the 
applicable emission standards.
    (i) Such notification shall include a full description of the 
addition or change and any supporting documentation the manufacturer may 
desire to include to support the manufacturer's determination in 
accordance with Sec.86.1844-01.
    (ii) The manufacturer's determination that the addition or change 
does

[[Page 1062]]

not cause noncompliance shall be based on an engineering evaluation of 
the addition or change and/or testing.
    (2) The Administrator may require that additional emission testing 
be performed to support the manufacturer's determination submitted in 
paragraph (b)(1) of this section. If additional testing is required the 
Administrator shall proceed in accordance with paragraph (a)(3) of this 
section. Additional test data, if requested, must be provided within 30 
days of the request or the manufacturer must rescind the addition or 
change immediately. The Administrator may grant additional time to 
complete testing. If based on this additional testing or any other 
information, the Administrator determines that the vehicles affected by 
the addition or change do not meet the applicable standards the 
Administrator will notify the manufacturer to rescind the addition or 
change immediately upon receipt of the notification.
    (c) Election to produce vehicles under this section will be deemed 
to be a consent to recall all vehicles which the Administrator 
determines under paragraph (a) or (b) of this section do not meet 
applicable standards, and to cause such nonconformity to be remedied at 
no expense to the owner.



Sec.86.1843-01  General information requirements.

Sec.86.1845-04  Manufacturer in-use verification testing requirements.

    (a) General requirements. (1) Manufacturers of LDV, LDT, MDPV and 
complete HDV must test, or cause to have tested, a specified number of 
vehicles. Such testing must be conducted in accordance with the 
provisions of this section.

[[Page 1069]]

    (2) Unless otherwise approved by the Administrator, no emission 
measurements made under the requirements of this section may be adjusted 
by Reactivity Adjustment Factors (RAFs).
    (3) The following provisions apply regarding the possibility of 
residual effects from varying fuel sulfur levels:
    (i) Vehicles certified to Tier 3 standards under Sec.86.1811 must 
always measure emissions over the FTP, then over the HFET (if 
applicable), then over the US06 portion of the SFTP. If a Tier 3 vehicle 
meets all the applicable emission standards except the FTP or HFET 
emission standard for NMOG + NOX, and a fuel sample from the 
tested vehicle (representing the as-received condition) has a measured 
fuel sulfur level exceeding 15 ppm when measured as described in 40 CFR 
1065.710, the manufacturer may repeat the FTP and HFET measurements and 
use the new emission values as the official results for that vehicle. 
For all other cases of testing Tier 3 vehicles, measured emission levels 
from the first test will be considered the official results for the test 
vehicle, regardless of any test results from additional test runs. Where 
repeat testing is allowed, the vehicle may operate for up to two US06 
cycles (with or without measurement) before repeating the FTP and HFET 
measurements. The repeat measurements must include both FTP and HFET, 
even if the vehicle failed only one of those tests, unless the HFET is 
not required for a particular vehicle. Tier 3 vehicles may not undergo 
any other vehicle preconditioning to eliminate fuel sulfur effects on 
the emission control system, unless we approve it in advance.
    (ii) Upon a manufacturer's written request, prior to in-use testing, 
that presents information to EPA regarding pre-conditioning procedures 
designed solely to remove the effects of high sulfur in gasoline from 
vehicles produced through the 2007 model year, EPA will consider 
allowing such procedures on a case-by-case basis. EPA's decision will 
apply to manufacturer in-use testing conducted under this section and to 
any in-use testing conducted by EPA. Such procedures are not available 
for complete HDV. For model year 2007 and later Tier 2 vehicles, this 
provision can be used only in American Samoa, Guam, and the Commonwealth 
of the Northern Mariana Islands, and then only if low sulfur gasoline is 
determined by the Administrator to be unavailable in that specific 
location.
    (b) Low-mileage testing--(1) Test groups. Testing must be conducted 
for each test group.
    (2) Vehicle mileage. All test vehicles must have a minimum odometer 
mileage of 10,000 miles.
    (3) Number of test vehicles. For each test group, the minimum number 
of vehicles that must be tested is specified in Table S04-06 and Table 
S04-07 of this paragraph (b)(3). After testing the minimum number of 
vehicles of a specific test group as specified in Table S04-06 or S04-07 
of this paragraph (b)(3), a manufacturer may test additional vehicles 
upon request and approval by the Agency prior to the initiation of the 
additional testing. Any additional testing must be completed within the 
testing completion requirements shown in Sec.86.1845-04(b)(4). The 
request and Agency approval (if any) shall apply to test groups on a 
case by case basis and apply only to testing under this paragraph. 
Separate approval will be required to test additional vehicles under 
paragraph (c) of this section. In addition to any testing that is 
required under Table S04-06 and Table S04-07, a manufacturer shall test 
one vehicle from each evaporative/refueling family for evaporative/
refueling emissions. If a manufacturer believes it is unable to procure 
the test vehicles necessary to test the required number of vehicles in a 
test group, the manufacturer may request, subject to Administrator 
approval, a decreased sample size for that test group. The request shall 
include a description of the methods the manufacturer has used to 
procure the required number of vehicles. The approval of any such 
request, and the substitution of an alternative sample size requirement 
for the test group, will be based on a review of the procurement efforts 
made by the manufacturer to determine if all reasonable steps have been 
taken to procure the required test group size. Tables S04-06 and S04-07 
follow:

  maximum of 14,999 vehicle 49 or 50 state annual sales, or a maximum of 4,500 vehicle California only sales per
  model year, per large volume manufacturer.
\3\ Sampling plan applies to all of a manufacturer's remaining groups in this sales volume category when the
  maximum annual cap on total sales of small groups eligible for the small volume sampling plan is exceeded.

    (4) Completion of testing. Testing of the vehicles in a test group 
and evaporative/refueling family must be completed within 12 months of 
the end of production of that test group (or evaporative/refueling 
family) for that model year.
    (5) Testing. (i) Each test vehicle of a test group shall be tested 
in accordance with the FTP and the US06 portion of the SFTP as described 
in subpart B of this part, when such test vehicle is tested for 
compliance with applicable exhaust emission standards under this 
subpart. Test vehicles subject to applicable exhaust CO2 
emission standards under this subpart shall also be tested in accordance 
with the HFET as described in 40 CFR 1066.840.
    (ii) For vehicles subject to Tier 3 PM standards, manufacturers must 
measure PM emissions over the FTP and US06 driving schedules for at 
least 50 percent of the vehicles tested under paragraph (b)(5)(i) of 
this section.
    (iii) Starting with model year 2018 vehicles, manufacturers must 
demonstrate compliance with the Tier 3 leak standard specified in Sec.
86.1813, if applicable, as described in this paragraph (b)(5)(iii). 
Manufacturers must evaluate each vehicle tested under paragraph 
(b)(5)(i) of this section, except that leak testing is not required for 
vehicles tested under paragraph (b)(5)(iv) of this section for diurnal 
emissions. In addition, manufacturers must evaluate at least one vehicle 
from each leak family for a given model year. Manufacturers may rely on 
OBD monitoring instead of testing as follows:
    (A) A vehicle is considered to pass the leak test if the OBD system 
completed a leak check within the previous 750 miles of driving without 
showing a leak fault code.
    (B) Whether or not a vehicle's OBD system has completed a leak check 
within the previous 750 miles of driving, the manufacturer may operate 
the vehicle as needed to force the OBD system to perform a leak check. 
If the OBD leak check does not show a leak fault, the vehicle is 
considered to pass the leak test.
    (C) If the most recent OBD leak check from paragraph (b)(5)(iii)(A) 
or (B) of this section shows a leak-related fault code as specified in 
Sec.86.1806-17(b), the vehicle is presumed to have failed the leak 
test. Manufacturers may perform the leak measurement procedure described 
in 40 CFR 1066.985 for an official result to replace the finding from 
the OBD leak check.
    (D) Manufacturers may not perform repeat OBD checks or leak 
measurements to over-ride a failure under paragraph (b)(5)(iii)(C) of 
this section.
    (iv) For nongaseous-fueled vehicles, one test vehicle of each 
evaporative/refueling family shall be tested in accordance with the 
supplemental 2-diurnal-plus-hot-soak evaporative emission and refueling 
emission procedures described in subpart B of this part, when such test 
vehicle is tested for compliance with applicable evaporative emission 
and refueling standards under this

[[Page 1071]]

subpart. For gaseous-fueled vehicles, one test vehicle of each 
evaporative/refueling family shall be tested in accordance with the 3-
diurnal-plus-hot-soak evaporative emission and refueling emission 
procedures described in subpart B of this part, when such test vehicle 
is tested for compliance with applicable evaporative emission and 
refueling standards under this subpart. The test vehicles tested to 
fulfill the evaporative/refueling testing requirement of this paragraph 
(b)(5)(iv) will be counted when determining compliance with the minimum 
number of vehicles as specified in Table S04-06 and Table S04-07 in 
paragraph (b)(3) of this section for testing under paragraph (b)(5)(i) 
of this section only if the vehicle is also tested for exhaust emissions 
under the requirements of paragraph (b)(5)(i) of this section.
    (6) Each test vehicle not rejected based on the criteria specified 
in appendix II to this subpart shall be tested in as-received condition.
    (7) A manufacturer may conduct subsequent diagnostic maintenance 
and/or testing of any vehicle. Any such maintenance and/or testing shall 
be reported to the Agency as specified in Sec.86.1847.
    (c) High-mileage testing--(1) Test groups. Testing must be conducted 
for each test group.
    (2) Vehicle mileage. All test vehicles must have a minimum odometer 
mileage of 50,000 miles. At least one vehicle of each test group must 
have a minimum odometer mileage of 105,000 miles or 75 percent of the 
full useful life mileage, whichever is less. See Sec.86.1838-01(c)(2) 
for small-volume manufacturer mileage requirements.
    (3) Number of test vehicles. For each test group, the minimum number 
of vehicles that must be tested is specified in Table S04-06 and Table 
S04-07 in paragraph (b)(3) of this section. After testing the minimum 
number of vehicles of a specific test group as specified in Table S04-06 
and Table S04-07 in paragraph (b)(3) of this section, a manufacturer may 
test additional vehicles upon request and approval by the Agency prior 
to the initiation of the additional testing. Any additional testing must 
be completed within the testing completion requirements shown in Sec.
86.1845-04(c)(4). The request and Agency approval (if any) shall apply 
to test groups on a case by case basis and apply only to testing under 
this paragraph (c). In addition to any testing that is required under 
Table S04-06 and Table S04-07, a manufacturer shall test one vehicle 
from each evaporative/refueling family for evaporative/refueling 
emissions. If a manufacturer believes it is unable to procure the test 
vehicles necessary to test the required number of vehicles in a test 
group as specified in Table S04-06 or Table S04-07, the manufacturer may 
request, subject to Administrator approval, a decreased sample size for 
that test group. The request shall include a description of the methods 
the manufacturer has used to procure the required number of vehicles. 
The approval of any such request, and the substitution of an alternative 
sample size requirement for the test group, will be based on a review of 
the procurement efforts made by the manufacturer to determine if all 
reasonable steps have been taken to procure the required test group 
size.
    (4) Initiation and completion of testing. Testing of a test group 
(or evaporative refueling family) must commence within 4 years of the 
end of production of the test group (or evaporative/refueling family) 
and be completed within 5 years of the end of production of the test 
group (or evaporative/refueling family).
    (5) Testing. (i) Each test vehicle shall be tested in accordance 
with the FTP and the US06 portion of the SFTP as described in subpart B 
of this part when such test vehicle is tested for compliance with 
applicable exhaust emission standards under this subpart. Test vehicles 
subject to applicable exhaust CO2 emission standards under 
this subpart shall also be tested in accordance with the HFET as 
described in 40 CFR 1066.840. One test vehicle from each test group 
shall be tested over the FTP at high altitude. The test vehicle tested 
at high altitude is not required to be one of the same test vehicles 
tested at low altitude. The test vehicle tested at high altitude is 
counted when determining the compliance with the requirements shown in 
Table S04-06 and Table S04-07 in paragraph (b)(3) of this section or the 
expanded

[[Page 1072]]

sample size as provided for in this paragraph (c).
    (ii) For vehicles subject to Tier 3 PM standards, manufacturers must 
measure PM emissions over the FTP and US06 driving schedules for at 
least 50 percent of the vehicles tested under paragraph (c)(5)(i) of 
this section.
    (iii) Starting with model year 2018 vehicles, manufacturers must 
evaluate each vehicle tested under paragraph (c)(5)(i) of this section 
to demonstrate compliance with the Tier 3 leak standard specified in 
Sec.86.1813, except that leak testing is not required for vehicles 
tested under paragraph (c)(5)(iv) of this section for diurnal emissions. 
In addition, manufacturers must evaluate at least one vehicle from each 
leak family for a given model year. Manufacturers may rely on OBD 
monitoring instead of testing as described in paragraph (b)(5)(iii) of 
this section.
    (iv) For nongaseous-fueled vehicles, one test vehicle of each 
evaporative/refueling family shall be tested in accordance with the 
supplemental 2-diurnal-plus-hot-soak evaporative emission procedures 
described in subpart B of this part, when such test vehicle is tested 
for compliance with applicable evaporative emission and refueling 
standards under this subpart. For gaseous-fueled vehicles, one test 
vehicle of each evaporative/refueling family shall be tested in 
accordance with the 3-diurnal-plus-hot-soak evaporative emission 
procedures described in subpart B of this part, when such test vehicle 
is tested for compliance with applicable evaporative emission and 
refueling standards under this subpart. The vehicles tested to fulfill 
the evaporative/refueling testing requirement of this paragraph 
(c)(5)(iv) will be counted when determining compliance with the minimum 
number of vehicles as specified in Table S04-06 and table S04-07 in 
paragraph (b)(3) of this section for testing under paragraph (c)(5)(i) 
of this section only if the vehicle is also tested for exhaust emissions 
under the requirements of paragraph (c)(5)(i) of this section.
    (6) Test condition. Each test vehicle not rejected based on the 
criteria specified in appendix II to this subpart shall be tested in as-
received condition.
    (7) Diagnostic maintenance. A manufacturer may conduct subsequent 
diagnostic maintenance and/or testing on any vehicle. Any such 
maintenance and/or testing shall be reported to the Agency as specified 
in Sec.86.1847-01.
    (d) Test vehicle procurement. (1) Vehicles tested under this section 
shall be procured pursuant to the provisions of this paragraph (d). 
Vehicles shall be procured from the group of persons who own or lease 
vehicles registered in the procurement area.
    (2) Vehicles shall be procured from persons which own or lease the 
vehicle, excluding commercial owners/lessees which are owned or 
controlled by the vehicle manufacturer, using the procedures described 
in appendix I to this subpart. See Sec.86.1838(c)(2)(i) for small 
volume manufacturer requirements.
    (3) Geographical limitations. (i) Test groups certified to 50-state 
standards: For low altitude testing no more than fifty percent of the 
test vehicles may be procured from California. The test vehicles 
procured from the 49 state area must be procured from a location with a 
heating degree day 30 year annual average equal to or greater than 4000.
    (ii) Test groups certified to 49 state standards: The test vehicles 
procured from the 49 state area must be procured from a location with a 
heating degree day 30 year annual average equal to or greater than 4000.
    (iii) Vehicles procured for high altitude testing may be procured 
from any area located above 4000 feet.
    (4) Vehicles may be rejected for procurement or testing under this 
section if they meet one or more of the rejection criteria in appendix 
II to this subpart. Vehicles may also be rejected after testing under 
this section if they meet one or more of the rejection criteria in 
appendix II to this subpart. Any vehicle rejected after testing must be 
replaced in order that the number of test vehicles in the sample comply 
with the sample size requirements of this section. Any post-test vehicle 
rejection and replacement procurement and testing must take place within 
the testing completion requirements of this section.
    (e) Testing facilities, procedures, quality assurance and quality 
control--(1) Lab

[[Page 1073]]

equipment and procedural requirements. The manufacturer shall utilize a 
test laboratory that is in accordance with the equipment and procedural 
requirements of subpart B of this part to conduct the testing required 
by this section.
    (2) The manufacturer shall notify the Agency of the name and 
location of the testing laboratory(s) to be used to conduct testing of 
vehicles of each model year conducted pursuant to this section. Such 
notification shall occur at least thirty working days prior to the 
initiation of testing of the vehicles of that model year.
    (3) Correlation. The manufacturer shall document correlation 
traceable to the Environmental Protection Agency's National Vehicle and 
Fuel Emission Laboratory for its test laboratory utilized to conduct the 
testing required by this section.
    (f)(1) A manufacturer must conduct in-use testing on a test group by 
determining NMOG exhaust emissions using the same methodology used for 
certification, as described in Sec.86.1810-01(o) or 40 CFR 1066.635.
    (2) For flexible-fueled vehicles certified to NMOG (or NMOG + 
NOX) standards, the manufacturer may ask for EPA approval to 
demonstrate compliance using an equivalent NMOG emission result 
calculated from a ratio of ethanol NMOG exhaust emissions to gasoline 
NMHC exhaust emissions. Ethanol NMOG exhaust emissions are measured 
values from testing with the ethanol test fuel, expressed as NMOG. 
Gasoline NMHC exhaust emissions are measured values from testing with 
the gasoline test fuel, expressed as NMHC. This ratio must be 
established during certification for each emission-data vehicle for the 
applicable test group. Use good engineering judgment to establish a 
different ratio for each duty cycle or test interval as appropriate. 
Identify the ratio values you develop under this paragraph (f)(2) and 
describe the duty cycle or test interval to which they apply in the Part 
II application for certification. Calculate the equivalent NMOG emission 
result by multiplying the measured gasoline NMHC exhaust emissions for a 
given duty cycle or test interval by the appropriate ratio.
    (3) If the manufacturer measures NMOG as described in 40 CFR 
1066.635(a), it must also measure and report HCHO emissions. As an 
alternative to measuring the HCHO content, if the manufacturer measures 
NMOG as permitted in 40 CFR 1066.635(c), the Administrator may approve, 
upon submission of supporting data by a manufacturer, the use of HCHO to 
NMHC ratios. To request the use of HCHO to NMHC ratios, the manufacturer 
must establish during certification testing the ratio of measured HCHO 
exhaust emissions to measured NMHC exhaust emissions for each emission-
data vehicle for the applicable test group. The results must be 
submitted to the Administrator with the Part II application for 
certification. Following approval of the application for certification, 
the manufacturer may conduct in-use testing on the test group by 
measuring NMHC exhaust emissions rather than HCHO exhaust emissions. The 
measured NMHC exhaust emissions must be multiplied by the HCHO to NMHC 
ratio submitted in the application for certification for the test group 
to determine the equivalent HCHO exhaust emission values for the test 
vehicle. The equivalent HCHO exhaust emission values must be compared to 
the HCHO exhaust emission standard applicable to the test group.

Sec.86.1846-01  Manufacturer in-use confirmatory testing requirements.

    (a) General requirements. (1) Manufacturers must test, or cause 
testing to be conducted, under this section when the emission levels 
shown by a test group sample from testing under Sec.86.1845 exceeds 
the criteria specified in paragraph (b) of this section. The testing 
required under this section applies separately to each test group and at 
each test point (low and high mileage) that meets the specified 
criteria. The testing requirements apply separately for each model year. 
These provisions apply to heavy-duty vehicles starting with model year 
2007. These provisions

[[Page 1074]]

do not apply to emissions of CO2, CH4, and 
N2O.
    (2) The provisions of Sec.86.1845-04(a)(3) regarding fuel sulfur 
effects apply equally to testing under this section.
    (b) Criteria for additional testing. (1) A manufacturer shall test a 
test group or a subset of a test group as described in paragraph (j) of 
this section when the results from testing conducted under Sec.86.1845 
show mean exhaust emissions for that test group of any pollutant(s) 
(except CO2, CH4, and N2O) to be equal 
to or greater than 1.30 times the applicable in-use standard and a 
failure rate, among the test group vehicles, for the corresponding 
pollutant(s) of fifty percent or greater.
    (i) Additional testing is not required under this paragraph (b)(1) 
based on evaporative/refueling testing or based on low-mileage 
Supplemental FTP testing conducted under Sec.86.1845-04(b)(5)(i). 
Testing conducted at high altitude under the requirements of Sec.
86.1845-04(c) will be included in determining if a test group meets the 
criteria triggering the testing required under this section.
    (ii) The vehicle designated for testing under the requirements of 
Sec.86.1845-04(c)(2) with a minimum odometer reading of 105,000 miles 
or 75% of useful life, whichever is less, will not be included in 
determining if a test group meets the triggering criteria.
    (iii) The SFTP composite emission levels shall include the IUVP FTP 
emissions, the IUVP US06 emissions, and the values from the SC03 Air 
Conditioning EDV certification test (without DFs applied). The 
calculations shall be made using the equations prescribed in Sec.
86.164. If more than one set of certification SC03 data exists (due to 
running change testing or other reasons), the manufacturer shall choose 
the SC03 result to use in the calculation from among those data sets 
using good engineering judgment.
    (2) If fewer than 50 percent of the vehicles from a leak family pass 
either the leak test or the diurnal test under Sec.86.1845, EPA may 
require further leak testing under this paragraph (b)(2). Testing under 
this section must include five vehicles from the family. If all five of 
these vehicles fail the test, the manufacturer must test five additional 
vehicles.
    EPA will determine whether to require further leak testing under 
this section after providing the manufacturer an opportunity to discuss 
the results, including consideration of any of the following 
information, or other items that may be relevant:
    (i) Detailed system design, calibration, and operating information, 
technical explanations as to why the individual vehicles tested failed 
the leak standard.
    (ii) Comparison of the subject vehicles to other similar models from 
the same manufacturer.
    (iii) Data or other information on owner complaints, technical 
service bulletins, service campaigns, special policy warranty programs, 
warranty repair data, state I/M data, and data available from other 
manufacturer-specific programs or initiatives.
    (iv) Evaporative emission test data on any individual vehicles that 
did not pass leak testing during IUVP.
    (c) Useful life. Vehicles tested under the provisions of this 
section must be within the useful life specified for the emission 
standards which were exceeded in the testing under Sec.86.1845. 
Testing should be within the useful life specified, subject to sections 
207(c)(5) and (c)(6) of the Clean Air Act where applicable.
    (d) Number of test vehicles. A manufacturer must test a minimum of 
ten vehicles of the test group or Agency-designated subset. A 
manufacturer may, at the manufacturer's discretion, test more than ten 
vehicles under this paragraph for a specific test group or Agency-
designated subset. If a manufacturer chooses to test more than the 
required ten vehicles, all testing must be completed within the time 
designated in the testing completion requirements of paragraph (g) of 
this section. Any vehicles which are eliminated from the sample either 
prior to or subsequent to testing, or any vehicles for which test 
results are determined to be void, must be replaced in order that the 
final sample of vehicles for which test results acceptable to the Agency 
are available equals a minimum of ten vehicles. A manufacturer may cease 
testing with a sample of five vehicles if the results of

[[Page 1075]]

the first five vehicles tested show mean emissions for each pollutant to 
be less than 75.0 percent of the applicable standard, with no vehicles 
exceeding the applicable standard for any pollutant.
    (e) Emission testing. Each test vehicle of a test group or Agency-
designated subset shall be tested in accordance with the FTP and/or the 
SFTP (whichever of these tests performed under Sec.86.1845 produces 
emission levels requiring testing under this section) as described in 
subpart B of this part, when such test vehicle is tested for compliance 
with applicable exhaust emission standards under this subpart.
    (f) Geographical limitations. (1) Test groups or Agency-designated 
subsets certified to 50-state standards: For low altitude testing no 
more than 50 percent of the test vehicles may be procured from 
California. The test vehicles procured from the 49 state area must be 
procured from a location with a heating degree day 30 year annual 
average equal to or greater than 4000.
    (2) Test groups or Agency-designated subsets certified to 49 state 
standards: For low-altitude testing all vehicles shall be procured from 
a location with a heating degree day 30 year annual average equal to or 
greater than 4000.
    (3) Vehicles procured for high altitude testing may be procured from 
any area provided that the vehicle's primary area of operation was above 
4000 feet.
    (g) Testing. Testing required under this section must commence 
within three months of completion of the testing under Sec.86.1845 
which triggered the confirmatory testing and must be completed within 
seven months of the completion of the testing which triggered the 
confirmatory testing. Any industry review of the results obtained under 
Sec.86.1845 and any additional vehicle procurement and/or testing 
which takes place under the provisions of Sec.86.1845 which the 
industry believes may affect the triggering of required confirmatory 
testing must take place within the three month period. The data and the 
manufacturers reasoning for reconsideration of the data must be provided 
to the Agency within the three month period.
    (h) Limit on manufacturer conducted testing. For each manufacturer, 
the maximum number of test group(s) (or Agency-designated subset(s)) of 
each model year for which testing under this section shall be required 
is limited to 50 percent of the total number of test groups of each 
model year required to be tested by each manufacturer as prescribed in 
Sec.86.1845, rounded to the next highest whole number where 
appropriate. For each manufacturer with only one test group under Sec.
86.1845, such manufacturer shall have a maximum potential testing 
requirement under this section of one test group (or Agency-designated 
subset) per model year.
    (i) Testing plan. Prior to beginning in-use confirmatory testing the 
manufacturer must, after consultation with the Agency, submit a written 
plan describing the details of the vehicle procurement, maintenance, and 
testing procedures (not otherwise specified by regulation) it intends to 
use. EPA must approve the test plan before the manufacturer may start 
further testing.
    (j) Testing a subset. EPA may designate a subset of the test group 
based on transmission type for testing under this section in lieu of 
testing the entire test group when the results for the entire test group 
from testing conducted under Sec.86.1845 show mean emissions and a 
failure rate which meet these criteria for additional testing.

Sec.86.1848-01  Certification.

    (a)(1) If, after a review of the manufacturer's submitted Part I 
application, information obtained from any inspection, such other 
information as the Administrator may require, and any other pertinent 
data or information, the Administrator determines that the application 
is complete and that all vehicles within a test group as described in 
the application meet the requirements of this part and the Clean Air 
Act, the Administrator shall issue a certificate of conformity.
    (2) If, after review of the manufacturer's application, request for 
certification, information obtained from any inspection, such other 
information as the Administrator may require, and any other pertinent 
data or information, the Administrator determines that the application 
is not complete or the vehicles within a test group as described in the 
application, do not meet applicable requirements or standards of the Act 
or of this part, the Administrator may deny the issuance of, suspend, or 
revoke a previously issued certificate of conformity. The Administrator 
will notify the manufacturer in writing, setting forth the basis for the 
determination. The manufacturer may request a hearing on the 
Administrator's determination.
    (b) A certificate of conformity will be issued by the Administrator 
for a period not to exceed one model year and upon such terms as deemed 
necessary or appropriate to assure that any new motor vehicle covered by 
the certificate will meet the requirements of the Act and of this part.
    (c) All certificates are conditional upon the following conditions 
being met:
    (1) The manufacturer must supply all required information according 
to the provisions of Sec. Sec.86.1843-01 and 86.1844-01.
    (2) The manufacturer must comply with all certification and in-use 
emission standards contained in subparts S and H of this part both 
during and after model year production.
    (3) The manufacturer must comply with all implementation schedules 
sales percentages as required in Sec.86.1810 or elsewhere in this 
part. Failure to meet a required implementation schedule sales 
percentage will be considered to be a failure to satisfy a condition 
upon which the certificate was issued and any vehicles or trucks sold in 
violation of the implementation schedule shall not be covered by the 
certificate.
    (4) For incomplete light-duty trucks and incomplete heavy-duty 
vehicles, a certificate covers only those new motor vehicles which, when 
completed by having the primary load-carrying device or container 
attached, conform to the maximum curb weight and frontal area 
limitations described in the application for certification as required 
in Sec.86.1844-01.
    (5) The manufacturer must meet the in-use testing and reporting 
requirements contained in Sec. Sec.86.1845-01, 86.1846-01, and 
86.1847-01, as applicable. Failure to meet the in-use testing or 
reporting requirements shall be considered a failure to satisfy a 
condition upon which the certificate was issued. A vehicle or truck will 
be considered to be covered by the certificate only if the manufacturer 
fulfills this condition upon which the certificate was issued.
    (6) Vehicles are covered by a certificate of conformity only if they 
are in all material respects as described in the manufacturer's 
application for certification (Part I and Part II).
    (7) For Tier 2 and interim non-Tier 2 vehicles, all certificates of 
conformity issued are conditional upon compliance with all provisions of 
Sec. Sec.86.1811-04,

[[Page 1078]]

86.1860-04, 86.1861-04 and 86.1862-04 both during and after model year 
production.
    (i) Failure to meet the fleet average NOX requirements of 
0.07g/mi, 0.30 g/mi or 0.20 g/mi, as applicable, will be considered to 
be a failure to satisfy the terms and conditions upon which the 
certificate(s) was (were) issued and the vehicles sold in violation of 
the fleet average NOX standard will not be covered by the 
certificate(s).
    (ii) Failure to comply fully with the prohibition against selling 
credits that it has not generated or that are not available, as 
specified in Sec.86.1861-04, will be considered to be a failure to 
satisfy the terms and conditions upon which the certificate(s) was 
(were) issued and the vehicles sold in violation of this prohibition 
will not be covered by the certificate(s).
    (iii) Failure to comply fully with the phase-in requirements of 
Sec.86.1811-04, will be considered to be a failure to satisfy the 
terms and conditions upon which the certificate(s) was (were) issued and 
the vehicles sold which do not comply with Tier 2 or interim non-Tier 2 
requirements, up to the number needed to comply, will not be covered by 
the certificate(s).
    (iv) For paragraphs (c)(7)(i) through (iii) of this section:
    (A) The manufacturer must bear the burden of establishing to the 
satisfaction of the Administrator that the terms and conditions upon 
which the certificate(s) was (were) issued were satisfied.
    (B) For recall and warranty purposes, vehicles not covered by a 
certificate of conformity will continue to be held to the standards 
stated or referenced in the certificate that otherwise would have 
applied to the vehicles.
    (d) One certificate will be issued for each test group and 
evaporative/refueling family combination. For diesel fueled vehicles, 
one certificate will be issued for each test group. A certificate of 
conformity is deemed to cover the vehicles named in such certificate and 
produced during the model year.
    (e) A manufacturer of new light-duty vehicles, light-duty trucks, 
and complete heavy-duty vehicles must obtain a certificate of conformity 
covering such vehicles from the Administrator prior to selling, offering 
for sale, introducing into commerce, delivering for introduction into 
commerce, or importing into the United States the new vehicle. Vehicles 
produced prior to the effective date of a certificate of conformity may 
also be covered by the certificate, once it is effective, if the 
following conditions are met:
    (1) The vehicles conform in all respects to the vehicles described 
in the application for the certificate of conformity.
    (2) The vehicles are not sold, offered for sale, introduced into 
commerce, or delivered for introduction into commerce prior to the 
effective date of the certificate of conformity.
    (3) EPA is notified prior to the beginning of production when such 
production will start, and EPA is provided a full opportunity to inspect 
and/or test the vehicles during and after their production. EPA must 
have the opportunity to conduct SEA production line testing as if the 
vehicles had been produced after the effective date of the certificate.
    (f) Vehicles imported by an original equipment manufacturer after 
December 31 of the calendar year for which the model year is named are 
still covered by the certificate of conformity as long as the production 
of the vehicle was completed before December 31 of that year.
    (g) For test groups required to have an emission control diagnostic 
system, certification will not be granted if, for any emission data 
vehicle or other test vehicle approved by the Administrator in 
consultation with the manufacturer, the malfunction indicator light does 
not illuminate under any of the circumstances described in Sec.
86.1806-01(k)(1) through (6).
    (h) Vehicles equipped with aftertreatment technologies such as 
catalysts, otherwise covered by a certificate, which are driven outside 
the United States, Canada, and Mexico will be presumed to have been 
operated on leaded gasoline resulting in deactivation of such components 
as catalysts and oxygen sensors. If these vehicles are imported or 
offered for importation without retrofit of the catalyst or other 
aftertreatment technology, they will be considered not to be within the

[[Page 1079]]

coverage of the certificate unless included in a catalyst or other 
aftertreatment technology control program operated by a manufacturer or 
a United States Government agency and approved by the Administrator.
    (i) For all light-duty vehicles and light light-duty trucks 
certified to NLEV standards under Sec. Sec.86.1710 through 86.1712, 
the following provisions apply:
    (1) All certificates issued are conditional upon manufacturer 
compliance with all provisions of Sec. Sec.86.1710 through 86.1712 
both during and after model year production.
    (2) Failure to meet the requirements of Sec.86.1710(a) through (d) 
will be considered to be a failure to satisfy the conditions upon which 
the certificate(s) was issued and the vehicles sold in violation of the 
fleet average NMOG standard shall not be covered by the certificate.
    (3) Failure to comply fully with the prohibition against a 
manufacturer selling credits that it has not generated or are not 
available, as specified in Sec.86.1710(e), will be considered to be a 
failure to satisfy the conditions upon which the certificate(s) was 
issued and the vehicles sold in violation of this prohibition shall not 
be covered by the certificate.
    (4) Failure to comply fully with the prohibition against offering 
for sale Tier 1 vehicles and TLEVs in the Northeast Trading Region, as 
defined in Sec.86.1702, after model year 2000 if vehicles with the 
same test groups are not certified and offered for sale in California in 
the same model year, as specified in Sec.86.1711(a), will be 
considered to be a failure to satisfy the conditions upon which the 
certificate(s) was issued and the vehicles sold in violation of this 
prohibition shall not be covered by the certificate.
    (5)(i) The Administrator will issue a National LEV certificate of 
conformity for 2000 model year vehicles or engines certified to comply 
with the California TLEV emission standards.
    (ii) This certificate of conformity shall be granted after the 
Administrator has received and reviewed the California Executive Order a 
manufacturer has received for the same vehicles or engines.
    (iii) Vehicles or engines receiving a certificate of conformity 
under the provisions in this paragraph can only be sold in the states 
included in the NTR, as defined in Sec.86.1702, and those states where 
the sale of California-certified vehicles is otherwise authorized.
    (6) The manufacturer shall bear the burden of establishing to the 
satisfaction of the Administrator that the conditions upon which the 
certificate was issued were satisfied.
    (7) For recall and warranty purposes, vehicles not covered by a 
certificate because of a violation of these conditions of the 
certificate will continue to be held to the standards stated in the 
certificate that would have otherwise applied to the vehicles.

Sec.86.1811-10 will be considered a failure to satisfy the terms and 
conditions upon which the certificate(s) was (were) issued and the 
vehicles sold that do not comply with cold temperature NMHC 
requirements, up to the number needed to comply, will not be covered by 
the certificate(s).

[[Page 1081]]

    (9) For 2012 and later model year LDVs, LDTs, and MDPVs, all 
certificates of conformity issued are conditional upon compliance with 
all provisions of Sec. Sec.86.1818 and 86.1865 both during and after 
model year production. Similarly, for 2014 and later model year HDV, and 
other HDV subject to standards under Sec.86.1819, all certificates of 
conformity issued are conditional upon compliance with all provisions of 
Sec. Sec.86.1819 and 86.1865 both during and after model year 
production. The manufacturer bears the burden of establishing to the 
satisfaction of the Administrator that the terms and conditions upon 
which the certificate(s) was (were) issued were satisfied. For recall 
and warranty purposes, vehicles not covered by a certificate of 
conformity will continue to be held to the standards stated or 
referenced in the certificate that otherwise would have applied to the 
vehicles.
    (i) Failure to meet the fleet average CO2 requirements 
will be considered a failure to satisfy the terms and conditions upon 
which the certificate(s) was (were) issued and the vehicles sold in

Sec.86.1849-01  Right of entry.

    (a) Any manufacturer who has applied for certification of a new 
motor vehicle subject to testing under this subpart, or any manufacturer 
or entity who conducts or causes to be conducted in-use verification or 
in-use confirmatory testing under this subpart, shall admit or cause to 
be admitted any EPA Enforcement Officer or any EPA authorized 
representative during operating hours on presentation of credentials to 
any of the following:
    (1) Any facility where any such certification or in-use verification 
or in-use confirmatory testing or any procedures or activities connected 
with such testing are or were performed.
    (2) Any facility where any new motor vehicle or test vehicle used 
for certification, in-use verification or in-use confirmatory testing 
which is being, was, or is to be tested is present.
    (3) Any facility where any construction process or assembly process 
used in the modification or build up of such a vehicle into a 
certification vehicle is taking place or has taken place.

[[Page 1082]]

    (4) Any facility where any record or other document relating to 
Sec.86.1849-01(a) (1), (2), and/or (3) is located.
    (b) Upon admission to any facility referred to in paragraph (a) of 
this section, any EPA official or EPA authorized representative shall be 
allowed:
    (1) To inspect and monitor any part or aspect of such procedures, 
activities, and testing facilities, including, but not limited to, 
monitoring vehicle preconditioning, emissions tests and mileage (or 
service) accumulation, bench aging, maintenance, and vehicle soak and 
storage procedures, and to verify correlation or calibration of test 
equipment.
    (2) To inspect and make copies of any such records, designs, or 
other documents, including those records specified in Sec. Sec.
86.1843-01, 86.1844-01, and 86.1847-01.
    (c) In order to allow the Administrator to determine whether or not 
production motor vehicles conform to the conditions upon which a 
certificate of conformity has been issued, or conform in all material 
respects to the design specifications which applied to those vehicles 
described in the certification application for which a certificate of 
conformity has been issued to standards prescribed under section 202 of 
the Act, any manufacturer shall admit any EPA Enforcement Officer or EPA 
authorized representative on presentation of credentials to:
    (1) Any facility where any document, design, or procedure relating 
to the translation of the design and construction of engines and 
emission-related components described in the compliance application or 
used for certification testing into production vehicles is located or 
carried on; and
    (2) Any facility where any motor vehicles to be introduced into 
commerce are manufactured or assembled.
    (d) Upon admission to any facility referred to in paragraph (c) of 
this section, any EPA Enforcement Officer or EPA authorized 
representative shall be allowed:
    (1) To inspect and monitor any aspects of such manufacture or 
assembly and other procedures;
    (2) To inspect and make copies of any such records, documents or 
designs; and
    (3) To inspect and photograph any part or aspect of any such new 
motor vehicles and any component used in the assembly thereof that are 
reasonably related to the purpose of the entry.
    (e) Any EPA official or EPA authorized representative shall be 
furnished by those in charge of a facility being inspected with such 
reasonable assistance as he may request to help him discharge any 
function set forth in this paragraph. Each applicant for or recipient of 
certification is required to cause those in charge of a facility 
operated for its benefit to furnish such reasonable assistance without 
charge to EPA whether or not the applicant controls the facility.
    (f) The duty to admit or cause to be admitted any EPA Enforcement 
Officer or EPA authorized representative applies whether or not the 
applicant owns or controls the facility in question and applies both to 
domestic and to foreign manufacturers and facilities. EPA will not 
attempt to make any inspections which it has been informed that local 
law forbids. However, if local law makes it impossible to what is 
necessary to insure the accuracy of data generated at a facility, no 
informed judgment that a vehicle is certifiable or is covered by a 
certificate can properly be based on those data. It is the 
responsibility of the manufacturer to locate its testing and 
manufacturing facilities in jurisdictions where this situation will not 
arise.
    (g) For purposes of this section:
    (1) ``Presentation of credentials'' shall mean display of the 
document designating a person as an EPA Enforcement Officer or EPA 
authorized representative.
    (2) Where vehicle, component, or engine storage areas or facilities 
are concerned, ``operating hours'' shall mean all times during which 
personnel other than custodial personnel are at work in the vicinity of 
the area or facility and have access to it.
    (3) Where facilities or areas other than those covered by paragraph 
(g)(2) of this section are concerned, ``operating hours'' shall mean all 
times during which an assembly line is in operation or all times during 
which testing,

[[Page 1083]]

maintenance, mileage (or service) accumulation, production or 
compilation of records, or any other procedure or activity related to 
certification testing, to translation of designs from the test stage to 
the production stage, or to vehicle (or engine) manufacture or assembly 
is being carried out in a facility.
    (4) Reasonable assistance includes, but is not limited to, clerical, 
copying, interpretation and translation services, the making available 
upon request of personnel of the facility being inspected during their 
working hours to inform the EPA Enforcement Officer or EPA authorized 
representative of how the facility operates and to answer his questions, 
and the performance on request of emissions tests on any vehicle which 
is being, has been, or will be used for certification or in-use 
verification or confirmatory testing. Such tests shall be 
nondestructive, but may require appropriate mileage (or service) 
accumulation. A manufacturer may be compelled to cause the personal 
appearance of any employee at such a facility before an EPA Enforcement 
Officer or EPA authorized representative by written request for his 
appearance, signed by the Assistant Administrator for Air and Radiation 
or the Assistant Administrator for Enforcement and Compliance Assurance, 
served on the manufacturer. Any such employee who has been instructed by 
the manufacturer to appear will be entitled to be accompanied, 
represented, and advised by counsel.



Sec.86.1850-01  Denial, suspension or revocation of certificate 
of conformity.

    (a) If, after review of the manufacturer's application, request for 
certification, information obtained from any inspection, such other 
information as the Administrator may require, and any other pertinent 
data or information, the Administrator determines that one or more test 
vehicles do not meet applicable requirements or standards of the Act or 
of this part, the Administrator will notify the manufacturer in writing, 
setting forth the basis for the determination. The manufacturer may 
request a hearing on the Administrator's determination.
    (b) Notwithstanding the fact that the vehicles described in the 
application may comply with all other requirements of this subpart, the 
Administrator may deny issuance of, suspend, or revoke a previously 
issued certificate of conformity if the Administrator finds any one of 
the following infractions to be substantial:
    (1) The manufacturer submits false or incomplete information.
    (2) The manufacturer denies an EPA enforcement officer or EPA 
authorized representative the opportunity to conduct authorized 
inspections as required under Sec.86.1849-01.
    (3) The manufacturer renders inaccurate any test data which it 
submits, or fails to make a good engineering judgment in accordance with 
Sec.86.1851-01(c)(1).
    (4) The manufacturer denies an EPA enforcement officer or EPA 
authorized representative reasonable assistance as required in Sec.
86.1849-01.
    (5) The manufacturer fails to provide the records required in Sec.
86.1844-01 to the Administrator within the deadline set forth in the 
request for such information.
    (6) The manufacturer fails to comply with all conditions under which 
the certificate of conformity was granted as specified in 86.1848-01.
    (7) The manufacturer otherwise circumvents the intent of the Act or 
of this part.
    (c) The manufacturer shall bear the burden of establishing to the 
satisfaction of the Administrator that the conditions upon which the 
certificate was issued were satisfied, or that any failure to satisfy a 
condition is not substantial.
    (d) If a manufacturer knowingly commits an infraction specified in 
paragraphs (b)(1) through (b)(7) of this section, knowingly commits any 
fraudulent act which results in the issuance of a certificate of 
conformity, or fails to comply with the conditions specified in Sec.
86.1843-01, the Administrator may deem such certificate void ab initio.
    (e) When the Administrator denies, suspends, revokes, or voids ab 
initio a certificate, EPA will provide the manufacturer a written 
determination. The manufacturer may request a hearing

[[Page 1084]]

under Sec.86.1853-01 on the Administrator's decision.
    (f) Any suspension or revocation of a certificate of conformity 
shall extend no further than to forbid the introduction into commerce of 
vehicles previously covered by the certificate which are still in the 
possession of the manufacturer, except in cases of such fraud or other 
misconduct that makes the certification void ab initio.



Sec.86.1851-01  Application of good engineering judgment to 
manufacturers' decisions.

    (a) The manufacturer shall exercise good engineering judgment in 
making all decisions called for under this subpart, including but not 
limited to selections, categorizations, determinations, and applications 
of the requirements of the subpart.
    (b) Upon written request by the Administrator, the manufacturer 
shall provide within 15 working days (or such longer period as may be 
allowed by the Administrator) a written description of the engineering 
judgment in question.
    (c) The Administrator may reject any such decision by a manufacturer 
if it is not based on good engineering judgment, or is otherwise 
inconsistent with the requirements of this subpart.
    (d) If the Administrator rejects a decision by a manufacturer with 
respect to the exercise of good engineering judgment, the following 
provisions shall apply:
    (1) If the Administrator determines that incorrect information was 
deliberately used in the decision process, that important information 
was deliberately overlooked, that the decision was not made in good 
faith, or that the decision was not made with a rational basis, the 
Administrator may suspend or void ab initio a certificate of conformity.
    (2) If the Administrator determines that the manufacturer's decision 
does not meet the provisions of paragraph (d)(1) of this section, but 
that a different decision would reflect a better exercise of good 
engineering judgment, then the Administrator will notify the 
manufacturer of this concern and the basis thereof.
    (i) The manufacturer shall have at least 30 days to respond to this 
notice. The Administrator may extend this response period upon request 
from the manufacturer if it is necessary to generate additional data for 
the manufacturer's response.
    (ii) The Administrator shall make the final ruling after considering 
the information provided by the manufacturer during the response period. 
If the Administrator determines that the manufacturer's decision was not 
made using good engineering judgment, he/she may reject that decision 
and apply the new ruling to future corresponding decisions as soon as 
practicable.
    (e) The Administrator shall notify the manufacturer in writing 
regarding any decision reached under paragraph (d)(1) or (2) of this 
section. The Administrator shall include in this notification the basis 
for reaching the determination.
    (f) Within 30 working days following receipt of notification of the 
Administrator's determinations made under paragraph (d) of this section, 
the manufacturer may request a hearing on those determinations. The 
request shall be in writing, signed by an authorized representative of 
the manufacturer, and shall include a statement specifying the 
manufacturer's objections to the Administrator's determinations, and 
data or other analysis in support of such objections. If, after review 
of the request and supporting data or analysis, the Administrator finds 
that the request raises a substantial factual issue, he/she shall 
provide the manufacturer a hearing in accordance with Sec.86.1853-01 
with respect to such issue.



Sec.86.1852-01  Waivers for good in-use emission performance.

    (a) The Administrator may waive requirements of this subpart 
relating to development of emission-related information or test data if 
the Administrator determines with confidence that the in-use emission 
test verification data required in Sec.86.1845-01 are below the 
applicable emission standards for an appropriate period of time, and 
that such performance is likely to continue in subsequent model years.

[[Page 1085]]

    (b) Any waiver granted under paragraph (a) of this section will be 
granted only if the Administrator determines that the waived requirement 
is not needed to assure continued emission compliance and the 
Administrator will have sufficient testing and other information in 
order to make certification decisions.
    (c) Any waiver granted under paragraph (a) of this section would be 
limited in duration to a period of one model year, unless extended by 
the Administrator as a result of continued demonstrations of good in-use 
emission performance.
    (d) The Administrator reserves the right to deny or revoke a waiver 
which may have been granted if he/she determines that the manufacturer 
no longer qualifies for the waiver.



Sec.86.1853-01  Certification hearings.

    If a manufacturer's request for a hearing is approved, EPA will 
follow the hearing procedures specified in 40 CFR part 1068, subpart G.

    (3)(i) For any person to remove or render inoperative any device or 
element of design installed on or in a vehicle or engine in compliance 
with regulations under this subpart prior to its sale and delivery to 
the ultimate purchaser, or for any person knowingly to remove or render 
inoperative any such device or element of design after such sale and 
delivery to the ultimate purchaser.
    (ii) For any person to manufacture, sell or offer to sell, or 
install, any part or component intended for use with, or as part of, any 
vehicle or engine, where a principal effect of the part or component is 
to bypass, defeat, or render inoperative any device or element of design 
installed on or in a vehicle or engine in compliance with regulations 
issued under this subpart, and where the person knows or should know 
that the part or component is being offered for sale or installed for 
this use or put to such use.
    (4) For any manufacturer of a vehicle or engine subject to standards 
prescribed under this subpart:
    (i) To sell, offer for sale, introduce or deliver into commerce, or 
lease any such vehicle or engine unless the manufacturer has complied 
with the requirements of Section 207(a) and (b) of the Clean Air Act (42 
U.S.C. 7541(a), (b)) with respect to such vehicle or engine, and unless 
a label or tag is affixed to such vehicle or engine in accordance with 
Section 207(c)(3) of the Clean Air Act (42 U.S.C. 7541(c)(3)).

Sec. Sec.86.1855-86.1859  [Reserved]



Sec.86.1860-04  How to comply with the Tier 2 and interim non-Tier
2 fleet average NOX standards.

    (a) The fleet average standards referred to in this section are the 
corporate fleet average standards for FTP exhaust NOX 
emissions set forth in: Sec.86.1811-04(d) for Tier 2 LDV/Ts and MDPVs 
(0.07 g/mi); Sec.86.1811-04(l)(3) for interim non-Tier 2 LDV/LLDTs 
(0.30 g/mi); and, Sec.86.1811-04(l)(3) for interim non-Tier 2 HLDT/
MDPVs (0.20 g/mi). Unless otherwise indicated in this section, the 
provisions of this section apply to all three corporate fleet average 
standards, except that the interim non-Tier 2 fleet average 
NOX standards do not apply to a manufacturer whose U.S. LDV/T 
and MDPV sales are 100% Tier 2 LDV/Ts and MDPVs.
    (b)(1) Each manufacturer must comply with the applicable fleet 
average NOX standard, or standards, on a sales weighted 
average basis, at the end of each model year, using the procedure 
described in this section.
    (2) During a phase-in year, the manufacturer must comply with the 
applicable fleet average NOX standard for the required phase-
in percentage for that year as specified in Sec.86.1811-04(k)(1), or 
for the alternate phase-in percentage as permitted under Sec.86.1811-
04(k)(6).
    (c)(1)(i) Each manufacturer must separately compute the sales 
weighted averages of the individual NOX emission standards to 
which it certified all its Tier 2 vehicles, interim non-Tier 2 LDV/
LLDTs, and interim non-Tier 2 HLDT/MDPVs of a given model year as 
described in Sec.86.1804(l)(2).
    (ii) For model years up to and including 2008, manufacturers must 
compute separate NOX fleet averages for Tier 2 LDV/LLDTs and 
Tier 2 HLDT/MDPVs.

[[Page 1087]]

    (2)(i) For model years up to and including 2008, if a manufacturer 
certifies its entire U.S. sales of Tier 2 or interim non-Tier 2 LDV/
LLDTs or interim non-Tier 2 HLDT/MDPVs, to full useful life bins having 
NOX standards at or below the applicable fleet average 
NOX standard, that manufacturer may elect not to compute a 
fleet average NOX level for that category of vehicles. A 
manufacturer making such an election must not generate NOX 
credits for that category of vehicles for that model year.
    (ii) For model years after 2008, if a manufacturer certifies its 
entire U.S. sales of Tier 2 vehicles to full useful life bins having 
NOX standards at or below 0.07 gpm, that manufacturer may 
elect not to compute a fleet average NOX level for its Tier 2 
vehicles. A manufacturer making such an election must not generate 
NOX credits for that model year.
    (d) The sales weighted NOX fleet averages determined 
pursuant to paragraph (c) of this section must be compared with the 
applicable fleet average standard; 0.07 g/mi for NOX for Tier 
2 LDV/Ts and MDPVs, 0.30 g/mi for NOX for interim non-Tier 2 
LDV/LLDTs, and 0.20 g/mi for NOx for interim non-Tier 2 HLDT/MDPVs. Each 
manufacturer must comply on an annual basis with the fleet average 
standards by:
    (1) Showing that its sales weighted average NOX emissions 
of its LDV/LLDTs, HLDT/MDPVs or LDV/Ts, as applicable, are at or below 
the applicable fleet average standard; or
    (2) If the sales weighted average is not at or below the applicable 
fleet average standard, by obtaining and applying sufficient Tier 2 
NOX credits, interim non-Tier 2 LDV/LLDT NOX 
credits or interim non-Tier 2 HLDT/MDPV NOX credits, as 
appropriate, and as permitted under Sec.86.1861-04.
    (i) Manufacturers may not use NMOG credits generated under the NLEV 
program in subpart R of this part to meet any Tier 2 or interim non-Tier 
2 NOX fleet average standard.
    (ii) Tier 2 NOX credits may not be used to meet any fleet 
average interim non-Tier 2 NOX standard except as permitted 
by Sec.86.1860-04(e)(1).
    (iii) Interim non-Tier 2 NOX credits may not be used to 
meet the Tier 2 fleet average NOX standard.
    (iv) Interim non-Tier 2 NOX credits from HLDT/MDPVs may 
not be used to meet the fleet average NOX standard for 
interim non-Tier 2 LDV/LLDTs, and interim non-Tier 2 credits from LDV/
LLDTs may not be used to meet the fleet average NOX standard 
for interim non-Tier 2 HLDT/MDPVs.
    (e) (1) Manufacturers that cannot meet the requirements of paragraph 
(d) of this section, may carry forward a credit deficit for three model 
years, but must not carry such deficit into the fourth year. When 
applying credits to reduce or eliminate a deficit under the fleet 
average standard for interim LDV/LLDTs or interim HLDT/MDPVs, that has 
been carried forward into a year subsequent to its generation, a 
manufacturer may apply credits from Tier 2 LDV/LLDTs or Tier 2 HLDT/
MDPVs, respectively, as well as from the appropriate group of interim 
vehicles. A manufacturer must not use interim credits to reduce or 
eliminate any NOX credit deficit under the Tier 2 fleet 
average standard.
    (2) A manufacturer carrying a credit deficit into the third year 
must generate or obtain credits to offset that deficit and apply them to 
the deficit at a rate of 1.2:1, (i.e. deficits carried into the third 
model year must be repaid with credits equal to 120 percent of the 
deficit).
    (3) A manufacturer must not bank credits for future model years or 
trade credits to another manufacturer during a model year into which it 
has carried a deficit.
    (f) Computing fleet average NOX emissions. (1) 
Manufacturers must separately compute these fleet NOX 
averages using the equation contained in paragraph (f)(2) of this 
section:
    (i) Their Tier 2 LDV/LLDT and Tier 2 HLDT/MDPV fleet average 
NOX emissions for each model year through 2008;
    (ii) Their combined Tier 2 LDV/T and MDPV fleet average 
NOX emissions for each model year after 2008;
    (iii) Their interim non-Tier 2 LDV/LLDT fleet average NOX 
emissions for each model year through 2006; and
    (iv) Their interim non-Tier 2 HLDT/MDPV fleet average NOX 
emissions for each model year through 2008.
    (2) The equation for computing fleet average NOX 
emissions is as follows:

[[Page 1088]]

[GRAPHIC] [TIFF OMITTED] TR10FE00.012

Where:

N = The number of vehicles sold in the applicable category that were 
          certified for each corresponding NOX emission bin. 
          N must be based on vehicles counted to the point of first 
          sale.
Emission standard = The individual full useful life NOX 
          emission standard for each bin for which the manufacturer had 
          sales.

    (3) The results of the calculation in paragraph (f)(2) of this 
section must be rounded as required by Sec.86.1837-01.
    (4) When approved in advance by the Administrator, the numerator in 
the equation in paragraph (f)(2) of this section may be adjusted 
downward by the product of the number of HEVs from each NOX 
emission bin times a HEV NOX contribution factor determined 
through mathematical estimation of the reduction in NOX 
emissions over the test procedure used to certify the HEVs. The 
reduction in NOX emissions must be determined using good 
engineering judgement and reflect the relation in actual full useful 
life NOX emissions to the full useful life NOX 
standards for the certification bin applicable to the vehicles. The 
Administrator may require that calculation of the HEV NOX 
contribution factor include vehicle parameters such as vehicle weight, 
portion of time during the test procedure that the HEV operates with 
zero exhaust emissions, zero emission range, NOX emissions 
from fuel-fired heaters and NOX emissions from electricity 
production and storage.
    (g) Additional credits for vehicles certified to 150,000 mile useful 
lives. (1) A manufacturer may certify any test group to an optional 
useful life of 15 years or 150,000 miles, whichever occurs first.
    (2)(i) For any test group certified to the optional 15 year/150,000 
mile useful life, the manufacturer may generate additional 
NOX credits, except as prohibited in paragraph (g)(3) of this 
section.
    (ii) The manufacturer must calculate these extra NOX 
credits, where permitted, by substituting an adjusted NOX 
standard for the applicable NOX standard from the full useful 
life certification bin when it calculates the applicable fleet average 
NOX emissions by the procedure in paragraph (f) of this 
section. The adjusted standard must be equal to the applicable full 
useful life NOX standard multiplied by 0.85 and rounded to 
one more decimal place than the number of decimal places as the 
applicable full useful life NOX standard.
    (3) A manufacturer electing not to comply with applicable 
intermediate life standards as permitted under Sec.86.1811-04(c)(4) 
may not generate additional credits from vehicles certified to a useful 
life of 15 years/150,000 miles; except that, for bins where such 
intermediate life standards do not exist or are specifically deemed to 
be optional in Sec.86.1811-04(c)(4), the manufacturer may generate 
additional NOX credits from vehicles certified to a useful 
life of 15 years/150,000 miles.
    (h) Additional credits for vehicles certified to low bins. A 
manufacturer may obtain additional NOX credits by certifying 
vehicles to bins 1 and/or 2 in model years from 2001 through 2005 
subject to the following requirements:
    (1) When computing the fleet average Tier 2 NOX emissions 
using the formula in paragraph (f)(2) of this section, the manufacturer 
may multiply the number of vehicles certified to bins 1 and 2 by the 
applicable multiplier shown in Table S04-11 when computing the 
denominator in the formula. These multipliers may not be used after 
model year 2005. The table follows:

[[Page 1089]]

    (2) Optionally, instead of the process described in paragraph (h)(1) 
of this section, when computing Tier 2 NOX credits using the 
formula in Sec.86.1861-04(b)(1), the manufacturer may multiply the 
number of vehicles certified to bin 1 and bin 2 by the applicable 
multiplier shown in Table S04-11 in paragraph (h)(1) of this section 
when computing the ``Total number of Tier 2 Vehicles Sold, Including 
ZEVs and HEVs''. These multipliers may not be used after model year 
2005.

[65 FR 6866, Feb. 10, 2000, as amended at 66 FR 19310, Apr. 13, 2001]



Sec.86.1860-17  How to comply with the Tier 3 fleet-average standards.

    (a) You must show that you meet the applicable fleet-average NMOG + 
NOX standards from Sec. Sec.86.1811 and 86.1816 and the 
fleet-average evaporative emission standards from Sec.86.1813 as 
described in this section. Note that separate fleet-average calculations 
are required for the FTP and SFTP exhaust emission standards under Sec.
86.1811.
    (b) Calculate your fleet-average value for each model year for all 
vehicle models subject to a separate fleet-average standard using the 
following equation, rounded to the nearest 0.001 g/mile for NMOG + 
NOX emissions and the nearest 0.001 g/test for evaporative 
emissions:
[GRAPHIC] [TIFF OMITTED] TR28AP14.008

Where:

i = A counter associated with each separate Tier 3 test group or 
          evaporative family.
b = The number of separate Tier 3 test groups or evaporative families 
          from a given averaging set to which you certify your vehicles.
Ni = The actual nationwide sales for the model year for test 
          group or evaporative family i. Include allowances for 
          evaporative emissions as described in Sec.86.1813.
FELi = The FEL selected for test group or evaporative family 
          i. Disregard any separate standards that apply for in-use 
          testing or for testing under high-altitude conditions.
Ntotal = The actual nationwide sales for the model year for 
          all your Tier 3 vehicles from the averaging set, except as 
          described in paragraph (c) of this section. The pool of 
          vehicle models included in Ntotal may vary by model 
          year, and it may be different for evaporative standards, FTP 
          exhaust standards, and SFTP exhaust standards in a given model 
          year.

    (c) Do not include any of the following vehicles to calculate your 
fleet-average value:
    (1) Vehicles that you do not certify to the standards of this part 
because they are permanently exempted under 40 CFR part 85 or part 1068.
    (2) Exported vehicles.
    (3) Vehicles excluded under Sec.86.1801.
    (4) For model year 2017, do not include vehicle sales in California 
or the section 177 states for calculating the fleet average value for 
evaporative emissions.
    (d) Except as specified in paragraph (e) of this section, your 
calculated fleet-average value may not exceed the corresponding fleet-
average standard for the model year.
    (e) You may generate or use emission credits related to your 
calculated fleet-average value as follows:
    (1) You may generate emission credits as described in Sec.86.1861 
if your fleet-average value is below the corresponding fleet-average 
standard.
    (2) You may use emission credits as described in Sec.86.1861 if 
your fleet-average value is above the corresponding fleet-average 
standard. Except as specified in paragraph (e)(3) of this section, you 
must use enough credits for each model year to show that your adjusted 
fleet average value does not exceed the fleet-average standard.

[[Page 1090]]

    (3) The following provisions apply if you do not have enough 
emission credits to demonstrate compliance with a fleet-average standard 
in a given model year:
    (i) You may have a credit deficit for up to three model years within 
an averaging set under Sec.86.1861-17(c). You may not bank emission 
credits with respect to a given emission standard during a model year in 
which you have a credit deficit in the same averaging set. If you fail 
to meet the fleet-average standard for four consecutive model years, the 
vehicles causing you to exceed the fleet-average standard will be 
considered not covered by the certificate of conformity. You will be 
subject to penalties on an individual-vehicle basis for sale of vehicles 
not covered by a certificate of conformity.
    (ii) You must notify us in writing how you plan to eliminate the 
credit deficit within the specified time frame. If we determine that 
your plan is unreasonable or unrealistic, we may deny an application for 
certification for a test group or evaporative family if its bin standard 
or FEL would increase your credit deficit. We may determine that your 
plan is unreasonable or unrealistic based on a consideration of past and 
projected use of specific technologies, the historical sales mix of your 
vehicle models, your commitment to limit sales of higher-emission 
vehicles, and expected access to traded credits. We may also consider 
your plan unreasonable if your fleet-average emission level increases 
relative to the first model year of a credit deficit or any later model 
year. We may require that you send us interim reports describing your 
progress toward resolving your credit deficit over the course of a model 
year.
    (f) If the applicable bin standards and FELs for all your vehicle 
models are at or below a corresponding fleet-average standard for a 
given model year, and you do not want to generate emission credits, you 
may omit the calculations described in this section.
    (g) For purposes of calculating the statute of limitations, the 
following actions are all considered to occur at the expiration of the 
deadline for offsetting a deficit as specified in paragraph (e)(3) of 
this section:
    (1) Failing to meet the requirements of paragraph (e)(3) of this 
section.
    (2) Failing to satisfy the conditions upon which a certificate was 
issued relative to offsetting a deficit.
    (3) Selling, offering for sale, introducing or delivering into U.S. 
commerce, or importing vehicles that are found not to be covered by a 
certificate as a result of failing to offset a deficit.

[79 FR 23735, Apr. 28, 2014]



Sec.86.1861-04  How do the Tier 2 and interim non-Tier 2 NOX 
averaging, banking and trading programs work?

    (a) General provisions for Tier 2 credits and debits. (1) A 
manufacturer whose Tier 2 fleet average NOX emissions exceeds 
the 0.07 g/mile standard must complete the calculation at paragraph (b) 
of this section to determine the size of its NOX credit 
deficit. A manufacturer whose Tier 2 fleet average NOX 
emissions is less than or equal to the 0.07 g/mile standard must 
complete the calculation in paragraph (b) of this section if it desires 
to generate NOX credits. In either case, the number of 
credits or debits determined in the calculation at paragraph (b) of this 
section must be rounded to the nearest whole number.
    (2) Credits generated according to the calculation in paragraph 
(b)(1) of this section may be banked for future use or traded to another 
manufacturer.
    (3) NOX credits are not subject to any discount or 
expiration date except as required under the deficit carryforward 
provisions of Sec.86.1860-04(e)(2).
    (4) If a manufacturer calculates that it has negative credits 
(debits or a credit deficit) for a given model year, it must obtain 
sufficient credits, as required under Sec.86.1860-04(e)(2), from 
vehicles produced by itself or another manufacturer in a model year no 
later than the third model year following the model year for which it 
calculated the credit deficit. (Example: if a manufacturer calculates 
that it has a NOX credit deficit for the 2008 model year, it 
must obtain sufficient NOX credits to offset that deficit 
from its own production or that of other manufacturers' 2011 or earlier 
model year vehicles.)

[[Page 1091]]

    (6)(i) Manufacturers may not use NOX credits to comply 
with the NLEV requirements of subpart R of this part.
    (ii) Manufacturers may not use NMOG credits generated by vehicles 
certified to the NLEV requirements of subpart R of this part to comply 
with any NOX requirements of this subpart.
    (iii) Manufacturers may not use NOX credits generated by 
interim non-Tier 2 vehicles to comply with the fleet average 
NOX standard for Tier 2 vehicles.
    (iv) Manufacturers may not use NOX credits generated by 
Tier 2 vehicles to comply with any fleet average NOX standard 
for interim non-Tier 2 vehicles, except as permitted under Sec.
86.1860-04(e).
    (v) Manufacturers may not use NOX credits generated by 
interim non-Tier 2 LDV/LLDTs to comply with the fleet average 
NOX standard for interim non-Tier 2 HLDT/MDPVs.
    (vi) Manufacturers may not use NOX credits generated by 
interim non-Tier 2 HLDT/MDPVs to comply with the fleet average 
NOX standard for interim non-Tier 2 LDV/LLDTs.
    (vii) Manufacturers may not use NOX credits generated by 
Tier 2 LDV/LLDTs to comply with the Tier 2 NOX average 
standard for HLDT/MDPVs before the 2009 model year.
    (viii) Manufacturers may not use NOX credits generated by 
Tier 2 HLDT/MDPVs to comply with the Tier 2 NOX average 
standard for LDV/LLDTs before the 2009 model year.
    (7) Manufacturers may bank Tier 2 NOX credits for later 
use to meet the Tier 2 fleet average NOX standard or trade 
them to another manufacturer. Credits are earned on the last day of the 
model year. Before trading or carrying over credits to the next model 
year, a manufacturer must apply available credits to offset any credit 
deficit, where the deadline to offset that credit deficit has not yet 
passed.
    (8) There are no property rights associated with NOX 
credits generated under this subpart. Credits are a limited 
authorization to emit the designated amount of emissions. Nothing in 
this part or any other provision of law should be construed to limit 
EPA's authority to terminate or limit this authorization through a 
rulemaking.
    (b) Calculating Tier 2 credits and debits. (1) Manufacturers that 
achieve fleet average NOX values from the calculation in 
Sec.86.1860-04(f), lower than the applicable fleet average 
NOX standard, may generate credits for a given model year, in 
units of vehicle-g/mi NOX, determined in this equation:

[(Fleet Average NOX Standard)-(Manufacturer's Fleet Average 
NOX Value)] x (Total Number of Tier 2 Vehicles Sold, 
Including ZEVs and HEVs).

Where: The number of Tier 2 vehicles sold is based on the point of first 
          sale and does not include vehicles sold in California or a 
          state that adopts, and has in effect for that model year, 
          California emission requirements.

    (2) Where the result of the calculation in paragraph (b)(1) of this 
section is a negative number, the manufacturer must generate negative 
NOX credits (debits).
    (c) Early banking. (1)(i) Manufacturers may certify LDV/LLDTs to the 
Tier 2 FTP exhaust standards in Sec.86.1811-04 for model years 2001-
2003 in order to bank credits for use in the 2004 and later model years. 
Such vehicles must also meet SFTP exhaust emission standards specified 
in Sec.86.1811-04.
    (ii) Manufacturers may certify HLDT/MDPVs to the Tier 2 FTP exhaust 
standards in Sec.86.1811-04 for model years 2001-2007 in order to bank 
credits for use in the 2008 and later model years. Such vehicles must 
also meet applicable SFTP exhaust emission standards specified in Sec.
86.1811-04.
    (iii) This process is referred to as ``early banking'' and the 
resultant credits are referred to as ''early credits''. In order to bank 
early credits, a manufacturer must comply with all exhaust emission 
standards and requirements applicable to Tier 2 LDV/LLDTs and/or HLDT/
MDPVs, as applicable, except as allowed under paragraph (c)(4) of this 
section.
    (2) To generate early credits, a manufacturer must separately 
compute the sales weighted NOX average of the LDV/LLDTs and 
HLDT/MDPVs it certifies to the Tier 2 exhaust requirements and 
separately compute credits using the calculations in this section and in 
Sec.86.1860-04.

[[Page 1092]]

    (3) Early HLDT/MDPV credits may not be applied to LDV/LLDTs before 
the 2009 model year. Early LDV/LLDT credits may not be applied to HLDT/
MDPVs before the 2009 model year.
    (4) Manufacturers may generate early Tier 2 credits from LDVs, LDT1s 
and LDT2s that are certified to a full useful life of 100,000 miles, 
provided that the credits are prorated by a multiplicative factor of 
0.833 (the quotient of 100,000/120,000). Where a manufacturer has both 
100,000 and 120,000 mile full useful life vehicles for which it desires 
to bank early credits, it must compute the credits from each group of 
vehicles separately and then add them together.
    (5) Manufacturers may bank early credits for later use to meet the 
Tier 2 fleet average NOX standard or trade them to another 
manufacturer subject to the restriction in paragraph (c)(3) of this 
section.
    (6) Early credits must not be used to comply with the fleet average 
NOX standards for interim non-Tier 2 vehicles.
    (7) Nothing in this section prevents the use of the NMOG values of 
2003 and earlier model year LDV/LLDTs from being used in calculations of 
the NMOG fleet average and subsequent NMOG credit generation, under 
subpart R of this part.
    (d) Reporting and recordkeeping for Tier 2 NOX credits including 
early credits. Each manufacturer must comply with the reporting and 
recordkeeping requirements of Sec.86.1862-04.
    (e) Fleet average NOX debits. (1) Manufacturers must offset any 
debits for a given model year by the fleet average NOX 
reporting deadline for the third model year following the model year in 
which the debits were generated as required in Sec.86.1860.04(e)(2). 
Manufacturers may offset debits by generating credits or acquiring 
credits generated by another manufacturer.
    (2)(i) Failure to meet the requirements of paragraphs (a) through 
(d) of this section and of this paragraph (e), within the required 
timeframe for offsetting debits will be considered to be a failure to 
satisfy the conditions upon which the certificate(s) was issued and the 
individual noncomplying vehicles not covered by the certificate must be 
determined according to this section.
    (ii) If debits are not offset within the specified time period, the 
number of vehicles not meeting the fleet average NOX 
standards and not covered by the certificate must be calculated by 
dividing the total amount of debits for the model year by the fleet 
average NOX standard applicable for the model year in which 
the debits were first incurred.
    (iii) EPA will determine the vehicles for which the condition on the 
certificate was not satisfied by designating vehicles in those test 
groups with the highest certification NOX emission values 
first and continuing until a number of vehicles equal to the calculated 
number of noncomplying vehicles as determined above is reached. If this 
calculation determines that only a portion of vehicles in a test group 
contribute to the debit situation, then EPA will designate actual 
vehicles in that test group as not covered by the certificate, starting 
with the last vehicle produced and counting backwards.
    (3) If a manufacturer ceases production of LDV/Ts and MDPVs or is 
purchased by, merges with or otherwise combines with another 
manufacturer, the manufacturer continues to be responsible for 
offsetting any debits outstanding within the required time period. Any 
failure to offset the debits will be considered to be a violation of 
paragraph (e)(1) of this section and may subject the manufacturer to an 
enforcement action for sale of vehicles not covered by a certificate, 
pursuant to paragraph (e)(2) of this section.
    (4) For purposes of calculating the statute of limitations, a 
violation of the requirements of paragraph (e)(1) of this section, a 
failure to satisfy the conditions upon which a certificate(s) was issued 
and hence a sale of vehicles not covered by the certificate, all occur 
upon the expiration of the deadline for offsetting debits specified in 
paragraph (e)(1) of this section.
    (f) NOX credit transfers. (1) EPA may reject NOX credit 
transfers if the involved manufacturers fail to submit the credit 
transfer notification in the annual report.
    (2) A manufacturer may not sell credits that are not available for 
sale pursuant to the provisions in paragraphs (a)(2) and (a)(7) of this 
section.

[[Page 1093]]

    (3) In the event of a negative credit balance resulting from a 
transaction, both the buyer and seller are liable, except in cases 
involving fraud. EPA may void ab initio the certificates of conformity 
of all engine families participating in such a trade.
    (4)(i) If a manufacturer transfers a credit that it has not 
generated pursuant to paragraph (b) of this section or acquired from 
another party, the manufacturer will be considered to have generated a 
debit in the model year that the manufacturer transferred the credit. 
The manufacturer must offset such debits by the deadline for the annual 
report for that same model year.
    (ii) Failure to offset the debits within the required time period 
will be considered a failure to satisfy the conditions upon which the 
certificate(s) was issued and will be addressed pursuant to paragraph 
(e) of this section.
    (g) Interim non-Tier 2 NOX credits and debits; Interim non-Tier 2 
averaging, banking and trading. Interim non-Tier 2 NOX 
credits must be generated, calculated, tracked, averaged, banked, 
traded, accounted for and reported upon separately from Tier 2 credits. 
The provisions of this section applicable to Tier 2 NOX 
credits and debits and Tier 2 averaging banking and trading are 
applicable to interim non-Tier 2 LDV/LLDTs and interim non-Tier 2 HLDT/
MDPVs with the following exceptions:
    (1) Provisions for early banking under paragraph (c) of this section 
do not apply.
    (2) The fleet average NOX standard used for calculating 
credits is 0.30 grams per mile for interim non-Tier 2 LDV/LLDTs and 0.20 
g/mi for interim non-Tier 2 HLDT/MDPVs. (The interim non-Tier 2 
NOX standard of 0.30 (or 0.20) g/mi replaces 0.07 in the text 
and calculation in this section.)
    (3) Interim non-Tier 2 NOX credit deficits may be carried 
forward for three years subject to the requirements of Sec.86.1860-
04(e).

Sec.86.1861-17  How do the NMOG + NOX and evaporative emission credit
programs work?

    You may use emission credits for purposes of certification to show 
compliance with the applicable fleet-average NMOG + NOX 
standards from Sec. Sec.86.1811 and 86.1816 and the fleet-average 
evaporative emission standards from Sec.86.1813 as described in 40 CFR 
part 1037, subpart H, with certain exceptions and clarifications as 
specified in this section. MDPVs are subject to the same provisions of 
this section that apply to LDT4.
    (a) Calculate emission credits as described in this paragraph (a) 
instead of using the provisions of 40 CFR 1037.705. Calculate positive 
or negative emission credits relative to the applicable fleet-average 
standard. Calculate positive emission credits if your fleet-average 
level is below the standard. Calculate negative emission credits if your 
fleet-average value is above the standard. Calculate credits separately 
for each type of standard and for each averaging set. Calculate emission 
credits using the following equation, rounded to the nearest whole 
number:

Emission credit = Volume [middot] [Fleet average standard-Fleet average 
value]

Where:

Emission credit = The positive or negative credit for each discrete 
          fleet-average standard, in units of vehicle-grams per mile for 
          NMOG + NOX and vehicle-grams per test for 
          evaporative emissions.
Volume = Sales volume in a given model year from the collection of test 
          groups or evaporative families covered by the fleet-average 
          value, as described in Sec.86.1860.

    (b) The following restrictions apply instead of those specified in 
40 CFR 1037.740:
    (1) Except as specified in paragraph (b)(2) of this section, 
emission credits may be exchanged only within an averaging set, as 
follows:
    (i) HDV represent a separate averaging set with respect to all 
emission standards.
    (ii) Except as specified in paragraph (b)(1)(iii) of this section, 
LDV and LDT represent a single averaging set with respect to all 
emission standards. Note that FTP and SFTP credits are not 
interchangeable.

[[Page 1094]]

    (iii) LDV and LDT1 certified to standards based on a useful life of 
120,000 miles and 10 years together represent a single averaging set 
with respect to NMOG + NOX emission standards. Note that FTP 
and SFTP credits are not interchangeable.
    (iv) The following separate averaging sets apply for evaporative 
emission standards:
    (A) LDV and LDT1 together represent a single averaging set.
    (B) LDT2 represents a single averaging set.
    (C) HLDT represents a single averaging set.
    (D) HDV represents a single averaging set.
    (2) You may exchange evaporative emission credits across averaging 
sets as follows if you need additional credits to offset a deficit after 
the final year of maintaining deficit credits as allowed under paragraph 
(c) of this section:
    (i) You may exchange LDV/LDT1 and LDT2 emission credits.
    (ii) You may exchange HLDT and HDV emission credits.
    (3) Except as specified in paragraph (b)(4) of this section, credits 
expire after five years. For example, credits you generate in model year 
2018 may be used only through model year 2023.
    (4) For the Tier 3 declining fleet-average FTP and SFTP emission 
standards for NMOG + NOX described in Sec.86.1811-17(b)(8), 
credits generated in model years 2017 through 2024 expire after eight 
years, or after model year 2030, whichever comes first; however, these 
credits may not be traded after five years. This extended credit life 
also applies for small-volume manufacturers generating credits under 
Sec.86.1811-17(h)(1) in model years 2022 through 2024. Note that the 
longer credit life does not apply for heavy-duty vehicles, for vehicles 
certified under the alternate phase-in described in Sec.86.1811-
17(b)(9), or for vehicles generating early Tier 3 credits under Sec.
86.1811-17(b)(11) in model year 2017.
    (c) The credit-deficit provisions 40 CFR 1037.745 apply to the NMOG 
+ NOX and evaporative emission standards for Tier 3 vehicles.
    (d) The reporting and recordkeeping provisions of Sec.86.1862 
apply instead of those specified in 40 CFR 1037.730 and 1037.735.
    (e) The provisions of 40 CFR 1037.645 do not apply.

[79 FR 23735, Apr. 28, 2014]



Sec.86.1862-04  Maintenance of records and submittal of information
relevant to compliance with fleet-average standards.

    (a) Overview. This section describes reporting and recordkeeping

vehicles subject to a fleet-average standard under this subpart must 
establish and maintain all the following information in organized and 
indexed records for each model year:
    (i) Model year.
    (ii) Applicable fleet-average standard.
    (iii) Calculated fleet-average value.
    (iv) All values used in calculating the fleet-average value 
achieved.
    (2) The manufacturer producing any vehicle subject to the provisions 
in this section must keep all the following information for each 
vehicle:
    (i) Model year.
    (ii) Applicable fleet-average standard.
    (iii) EPA test group or evaporative family, as applicable.
    (iv) Assembly plant.
    (v) Vehicle identification number.
    (vi) The FEL and the fleet-average standard to which the vehicle is 
certified.
    (vii) Information on the point of first sale, including the 
purchaser, city, and state.

[[Page 1095]]

    (3) The manufacturer must retain all records required to be 
maintained under this section for a period of eight years from the due 
date for the annual report. Records may be stored in any format and on 
any media, as long as manufacturers can promptly send EPA organized 
written records in English if we ask for them. Manufacturers must keep 
records readily available as EPA may review them at any time.
    (4) The Administrator may require the manufacturer to retain 
additional records or submit information not specifically required by 
this section.
    (5) EPA may void ab initio a certificate of conformity for a vehicle 
certified to emission standards as set forth or otherwise referenced in 
this subpart for which the manufacturer fails to retain the records 
required in this section, to provide such information to the 
Administrator upon request, or to submit the reports required in this 
section in the specified time period.
    (c) Reporting. (1) Each manufacturer must submit an annual report. 
Except as provided in paragraph (b)(2) of this section, the annual 
report must contain, for each applicable fleet average standard, the 
fleet average value achieved, all values required to calculate the 
fleet-average value, the number of credits generated or debits incurred, 
all the values required to calculate the credits or debits, and 
sufficient information to show compliance with all phase-in 
requirements, if applicable. The annual report must also contain the 
resulting balance of credits or debits.
    (2) When a manufacturer calculates compliance with the fleet-average 
standard using the provisions in Sec.86.1860-04(c)(2) or Sec.
86.1860-17(f), the annual report must state that the manufacturer has 
elected to use such provision and must contain the fleet-average 
standard as the fleet-average value for that model year.
    (3) For each applicable fleet-average standard, the annual report 
must also include documentation on all credit transactions the 
manufacturer has engaged in since those included in the last report. 
Information for each transaction must include all the following 
information:
    (i) Name of credit provider.
    (ii) Name of credit recipient.
    (iii) Date the transfer occurred.
    (iv) Quantity of credits transferred.
    (v) Model year in which the credits were earned.
    (4) Unless a manufacturer reports the data required by this section 
in the annual production report required under Sec.86.1844-01(e) and 
subsequent model year provisions, a manufacturer must submit an annual 
report for each model year after production ends for all affected 
vehicles produced by the manufacturer subject to the provisions of this 
subpart and no later than May 1 of the calendar year following the given 
model year. Annual reports must be submitted to: Director, Compliance 
Division, U.S. Environmental Protection Agency, 2000 Traverwood, Ann 
Arbor, Michigan 48105.
    (5) Failure by a manufacturer to submit the annual report in the 
specified time period for all vehicles subject to the provisions in this 
section is a violation of Clean Air Act section 203(a)(1) (42 U.S.C 
7522(a)(1)) for each subject vehicle produced by that manufacturer.
    (6) If EPA or the manufacturer determines that a reporting error 
occurred on an annual report previously submitted to EPA, the 
manufacturer's credit or debit calculations will be recalculated. EPA 
may void erroneous credits, unless transferred, and must adjust 
erroneous debits. In the case of transferred erroneous credits, EPA must 
adjust the selling manufacturer's credit or debit balance to reflect the 
sale of such credits and any resulting generation of debits.
    (d) Notice of opportunity for hearing. Any voiding of the 
certificate under paragraph (a)(6) of this section will be made only 
after EPA has offered the manufacturer concerned an opportunity for a 
hearing conducted in accordance with 40 CFR part 1068, subpart G and, if 
a manufacturer requests such a hearing, will be made only after an 
initial decision by the Presiding Officer.

Sec.86.1863-07  Optional chassis certification for diesel vehicles.

    This section does not apply for vehicles certified to the Tier 3 
standards in Sec.86.1816-18, including those vehicles that certify to 
the Tier 3 standards before model year 2018.
    (a) A manufacturer may optionally certify heavy-duty diesel vehicles 
14,000 pounds GVWR or less to the standards specified in Sec.86.1816. 
Such vehicles must meet all the requirements of this subpart S that are 
applicable to Otto-cycle vehicles, except for evaporative, refueling,

81 FR 73992, Oct. 25, 2016]



Sec.86.1864-10  How to comply with the fleet average cold temperature
NMHC standards.

    (a) Applicability. Cold temperature NMHC exhaust emission standards 
apply to the following vehicles, subject to the phase-in requirements in 
Sec.86.1811-10(g)(3) and (4):
    (1) 2010 and later model year LDV/LLDTs.
    (2) 2012 and later model year HLDT/MDPVs.
    (3) [Reserved]
    (4) Vehicles imported by ICIs as defined in 40 CFR 85.1502.
    (b) Useful life requirements. Full useful life requirements for cold 
temperature NMHC standards are defined in Sec.86.1805-04(g). There is 
not an intermediate useful life standard for cold temperature NMHC 
standards.
    (c) Altitude. Altitude requirements for cold temperature NMHC 
standards are provided in Sec.86.1810-09(f).
    (d) Small volume manufacturer certification procedures. 
Certification procedures for small volume manufacturers are provided in 
Sec.86.1838-01.
    (e) Cold temperature NMHC standards. Fleet average cold temperature 
NMHC standards are provided in Sec.86.1811-10(g)(2).
    (f) Phase-in. Phase-in of the cold temperature NMHC standards are 
provided in Sec.86.1811-10(g)(3) and (4).
    (g) Phase-in flexibilities for small volume manufacturers. Phase-in 
flexibilities for small volume manufacturer compliance with the cold 
temperature NMHC standards are provided in Sec.86.1811-04(k)(5).
    (h) Hardship provisions for small volume manufacturers. Hardship 
provisions for small volume manufacturers related to the cold 
temperature NMHC standards are provided in Sec.86.1811-04(q)(1).
    (i) In-use standards for applicable phase-in models. In-use cold 
temperature NMHC standards for applicable phase-in models are provided 
in Sec.86.1811-10(u).
    (j) Durability procedures and method of determining deterioration 
factors (DFs). The durability data vehicle selection procedures of Sec.
86.1822-01 and the durability demonstration procedures of Sec.86.1823-
06 apply for cold temperature NMHC standards. For determining

[[Page 1097]]

compliance with full useful life cold temperature NMHC emission 
standards, the 68-86 [deg]F, 120,000 mile full useful life NMOG DF may 
be used.
    (k) Vehicle test procedure. (1) The test procedure for demonstrating 
compliance with cold temperature NMHC standards is contained in subpart 
C of this part. With prior EPA approval, alternative testing procedures 
may be used, as specified in Sec.86.106-96(a), provided cold 
temperature NMHC emissions test results are equivalent or superior.
    (2) Testing of all LDVs, LDTs and MDPVs to determine compliance with 
cold temperature NMHC exhaust emission standards set forth in this 
section must be on a loaded vehicle weight (LVW) basis, as defined in 
Sec.86.1803-01.
    (3) Testing for the purpose of providing certification data is 
required only at low altitude conditions and only for vehicles that can 
operate on gasoline, except as requested in Sec. Sec.86.1810-09(f) and 
86.1844-01(d)(11). If hardware and software emission control strategies 
used during low altitude condition testing are not used similarly across 
all altitudes for in-use operation, the manufacturer must include a 
statement in the application for certification, in accordance with 
Sec. Sec.86.1844-01(d)(11) and 86.1810-09(f), stating what the 
different strategies are and why they are used. If hardware and software 
emission control strategies used during testing with gasoline are not 
used similarly with all fuels that can be used in multi-fuel vehicles, 
the manufacturer will include a statement in the application for 
certification, in accordance with Sec. Sec.86.1844-01(d)(11) and 
86.1810-09(f), stating what the different strategies are and why they 
are used. For example, unless a manufacturer states otherwise, air pumps 
used to control emissions on dedicated gasoline vehicles or multi-fuel 
vehicles during low altitude conditions must also be used to control 
emissions at high altitude conditions, and software used to control 
emissions or closed loop operation must also operate similarly at low 
and high altitude conditions and similarly when multi-fueled vehicles 
are operated on gasoline and alternate fuels. These examples are for 
illustrative purposes only; similar strategies would apply to other 
currently used emission control technologies and/or emerging or future 
technologies.
    (l) Emission data vehicle (EDV) selection. Provisions for selecting 
the appropriate EDV for the cold temperature NMHC standards are provided 
in Sec. Sec.86.1828-10(g) and 86.1829-01(b)(3).
    (m) Calculating the fleet average cold temperature NMHC standard. 
Manufacturers must compute separate sales-weighted fleet average cold 
temperature NMHC emissions at the end of the model year for LDV/LLDTs 
and HLDT/MDPVs, using actual sales, and certifying test groups to FELs, 
as defined in Sec.86.1803-01. The FEL becomes the standard for each 
test group, and every test group can have a different FEL. The 
certification resolution for the FEL will be 0.1 grams/mile. LDVs and 
LLDTs must be grouped together when calculating the fleet average, and 
HLDTs and MDPVs must also be grouped together to determine the fleet 
average. Manufacturers must compute the sales-weighted cold temperature 
NMHC fleet averages using the following equation, rounded to the nearest 
0.1 grams/mile:

Fleet average cold temperature NMHC exhaust emissions (grams/mile) = 
[Sigma](N x FEL) / Total number of vehicles sold of the applicable 
weight category (i.e., either LDV + LLDTs, or HLDT + MDPVs)
Where:

N = The number of LDVs and LLDTs, or HLDTs and MDPVs, sold within the 
          applicable FEL, based on vehicles counted to the point of 
          first sale.
FEL = Family Emission Limit (grams/mile).

    (n) Certification compliance and enforcement requirements for cold 
temperature NMHC standards. (1) Compliance and enforcement requirements 
are provided in Sec.86.1864-10 and Sec.86.1848-10(c)(8).
    (2) The certificate issued for each test group requires all vehicles 
within that test group to meet the emission standard or FEL to which the 
vehicles were certified.
    (3) Each manufacturer must comply with the applicable cold 
temperature NMHC fleet average standard on a sales-weighted average 
basis, at the end of each model year, using the procedure described in 
paragraph (m) of this section.

[[Page 1098]]

    (4) During a phase-in year, the manufacturer must comply with the 
applicable cold temperature NMHC fleet average standard for the required 
phase-in percentage for that year as specified in Sec.86.1811-10(g)(3) 
or (4).
    (5) Manufacturers must compute separate cold temperature NMHC fleet 
averages for LDV/LLDTs and HLDT/MDPVs. The sales-weighted cold 
temperature NMHC fleet averages must be compared with the applicable 
fleet average standard.
    (6) Each manufacturer must comply on an annual basis with the fleet 
average standards as follows:
    (i) Manufacturers must report in their annual reports to the Agency 
that they met the relevant corporate average standard by showing that 
their sales-weighted average cold temperature NMHC emissions of LDV/
LLDTs and HLDT/MDPVs, as applicable, are at or below the applicable 
fleet average standard;
    (ii) If the sales-weighted average is above the applicable fleet 
average standard, manufacturers must obtain and apply sufficient NMHC 
credits as permitted under paragraph (o)(8) of this section. A 
manufacturer must show via the use of credits that they have offset any 
exceedence of the corporate average standard. Manufacturers must also 
include their credit balances or deficits.
    (iii) If a manufacturer fails to meet the corporate average cold 
temperature NMHC standard for two consecutive years, the vehicles 
causing the corporate average exceedence will be considered not covered 
by the certificate of conformity (see paragraph (o)(8) of this section). 
A manufacturer will be subject to penalties on an individual-vehicle 
basis for sale of vehicles not covered by a certificate.
    (iv) EPA will review each manufacturer's sales to designate the 
vehicles that caused the exceedence of the corporate average standard. 
EPA will designate as nonconforming those vehicles in test groups with 
the highest certification emission values first, continuing until 
reaching a number of vehicles equal to the calculated number of 
noncomplying vehicles as determined above. In a group where only a 
portion of vehicles would be deemed nonconforming, EPA will determine 
the actual nonconforming vehicles by counting backwards from the last 
vehicle produced in that test group. Manufacturers will be liable for 
penalties for each vehicle sold that is not covered by a certificate.
    (o) Requirements for the cold temperature NMHC averaging, banking 
and trading (ABT) program. (1) Manufacturers must average the cold 
temperature NMHC emissions of their vehicles and comply with the cold 
temperature NMHC fleet average corporate standard. Manufacturers may 
generate credits during and after the phase-in period. Manufacturers may 
generate credits prior to the phase-in periods as described in paragraph 
(o)(5) of this section. A manufacturer whose cold temperature NMHC fleet 
average emissions exceed the applicable standard must complete the 
calculation in paragraph (o)(4) of this section to determine the size of 
its NMHC credit deficit. A manufacturer whose cold temperature NMHC 
fleet average emissions are less than the applicable standard must 
complete the calculation in paragraph (o)(4) of this section to generate 
NMHC credits.
    (2) There are no property rights associated with NMHC credits 
generated under this subpart. Credits are a limited authorization to 
emit the designated amount of emissions. Nothing in this part or any 
other provision of law should be construed to limit EPA's authority to 
terminate or limit this authorization through a rulemaking.
    (3) Each manufacturer must comply with the reporting and 
recordkeeping requirements of paragraph (p) of this section for NMHC 
credits, including early credits. The averaging, banking and trading 
program is enforceable through the certificate of conformity that allows 
the manufacturer to introduce any regulated vehicles into commerce.
    (4) Credits are earned on the last day of the model year. 
Manufacturers must calculate, for a given model year, the number of 
credits or debits it has generated according to the following equation, 
rounded to the nearest 0.1 grams/mile:


[[Page 1099]]


NMHC Credits or Debits = (Cold Temperature NMHC Standard--Manufacturer's 
Sales-Weighted Fleet Average Cold Temperature NMHC Emissions) x (Total 
Number of Vehicles Sold)

Where:

Cold Temperature NMHC Standard = 0.3 grams/mile for LDV/LLDTs or 0.5 
          grams/mile for HLDT/MDPV, per Sec.86.1811-10(g)(2).
Manufacturer's Sales-Weighted Fleet Average Cold Temperature NMHC 
          Emissions = average calculated according to paragraph (m) of 
          this section.
Total Number of Vehicles Sold = Total 50-State sales based on the point 
          of first sale.

    (5) The following provisions apply for early banking:
    (i) Manufacturers may certify LDV/LLDTs to the cold temperature NMHC 
exhaust standards in Sec.86.1811-10(g)(2) for model years 2008-2009 to 
bank credits for use in the 2010 and later model years. Manufacturers 
may certify HLDT/MDPVs to the cold temperature NMHC exhaust standards in 
Sec.86.1811-10(g)(2) for model years 2010-2011 to bank credits for use 
in the 2012 and later model years.
    (ii) This process is referred to as ``early banking'' and the 
resultant credits are referred to as ``early credits.'' To bank early 
credits, a manufacturer must comply with all exhaust emission standards 
and requirements applicable to LDV/LLDTs and/or HLDT/MDPVs. To generate 
early credits, a manufacturer must separately compute the sales-weighted 
cold temperature NMHC average of the LDV/LLDTs and HLDT/MDPVs it 
certifies to the exhaust requirements and separately compute credits 
using the calculations in paragraph (o)(4) of this section. Early HLDT/
MDPV credits may not be applied to LDV/LLDTs before the 2010 model year. 
Early LDV/LLDT credits may not be applied to HLDT/ MDPV before the 2012 
model year.
    (6) NMHC credits are not subject to any discount or expiration date 
except as required under the deficit carryforward provisions of 
paragraph (o)(8) of this section. There is no discounting of unused 
credits. NMHC credits have unlimited lives, subject to the limitations 
of paragraph (o)(2) of this section.
    (7) Credits may be used as follows:
    (i) Credits generated and calculated according to the method in 
paragraph (o)(4) of this section may be used only to offset deficits 
accrued with respect to the standard in Sec.86.1811-10(g)(2). Credits 
may be banked and used in a future model year in which a manufacturer's 
average cold temperature NMHC level exceeds the applicable standard. 
Credits may be exchanged between the LDT/LLDT and HLDT/MDPV fleets of a 
given manufacturer. Credits may also be traded to another manufacturer 
according to the provisions in paragraph (o)(9) of this section. Before 
trading or carrying over credits to the next model year, a manufacturer 
must apply available credits to offset any credit deficit, where the 
deadline to offset that credit deficit has not yet passed.
    (ii) The use of credits shall not be permitted to address Selective 
Enforcement Auditing or in-use testing failures. The enforcement of the 
averaging standard occurs through the vehicle's certificate of 
conformity. A manufacturer's certificate of conformity is conditioned 
upon compliance with the averaging provisions. The certificate will be 
void ab initio if a manufacturer fails to meet the corporate average 
standard and does not obtain appropriate credits to cover its shortfalls 
in that model year or in the subsequent model year (see deficit 
carryforward provision in paragraph (o)(8) of this section). 
Manufacturers must track their certification levels and sales unless 
they produce only vehicles certified to cold temperature NMHC levels 
below the standard and do not plan to bank credits.
    (8) The following provisions apply if debits are accrued:
    (i) If a manufacturer calculates that it has negative credits (also 
called ``debits'' or a ``credit deficit'') for a given model year, it 
may carry that deficit forward into the next model year. Such a carry-
forward may only occur after the manufacturer exhausts any supply of 
banked credits. At the end of that next model year, the deficit must be 
covered with an appropriate

[[Page 1100]]

number of credits that the manufacturer generates or purchases. Any 
remaining deficit is subject to an enforcement action, as described in 
this paragraph (o)(8). Manufacturers are not permitted to have a credit 
deficit for two consecutive years.
    (ii) If debits are not offset within the specified time period, the 
number of vehicles not meeting the fleet average cold temperature NMHC 
standards (and therefore not covered by the certificate) must be 
calculated by dividing the total amount of debits for the model year by 
the fleet average cold temperature NMHC standard applicable for the 
model year in which the debits were first incurred.
    (iii) EPA will determine the number of vehicles for which the 
condition on the certificate was not satisfied by designating vehicles 
in those test groups with the highest certification cold temperature 
NMHC emission values first and continuing until reaching a number of 
vehicles equal to the calculated number of noncomplying vehicles as 
determined above. If this calculation determines that only a portion of 
vehicles in a test group contribute to the debit situation, then EPA 
will designate actual vehicles in that test group as not covered by the 
certificate, starting with the last vehicle produced and counting 
backwards.
    (iv)(A) If a manufacturer ceases production of LDV/LLDTs and HLDT/
MDPVs, the manufacturer continues to be responsible for offsetting any 
debits outstanding within the required time period. Any failure to 
offset the debits will be considered a violation of paragraph (o)(8)(i) 
of this section and may subject the manufacturer to an enforcement 
action for sale of vehicles not covered by a certificate, pursuant to 
paragraphs (o)(8)(ii) and (iii) of this section.
    (B) If a manufacturer is purchased by, merges with, or otherwise 
combines with another manufacturer, the controlling entity is 
responsible for offsetting any debits outstanding within the required 
time period. Any failure to offset the debits will be considered a 
violation of paragraph (o)(8)(i) of this section and may subject the 
manufacturer to an enforcement action for sale of vehicles not covered 
by a certificate, pursuant to paragraphs (o)(8)(ii) and (iii) of this 
section.
    (v) For purposes of calculating the statute of limitations, a 
violation of the requirements of paragraph (o)(8)(i) of this section, a 
failure to satisfy the conditions upon which a certificate(s) was issued 
and hence a sale of vehicles not covered by the certificate, all occur 
upon the expiration of the deadline for offsetting debits specified in 
paragraph (o)(8)(i) of this section.
    (9) The following provisions apply to NMHC credit trading:
    (i) EPA may reject NMHC credit trades if the involved manufacturers 
fail to submit the credit trade notification in the annual report. A 
manufacturer may not sell credits that are not available for sale 
pursuant to the provisions in paragraphs (o)(7)(i) of this section.
    (ii) In the event of a negative credit balance resulting from a 
transaction that a manufacturer could not cover by the reporting 
deadline for the model year in which the trade occurred, both the buyer 
and seller are liable, except in cases involving fraud. EPA may void ab 
initio the certificates of conformity of all engine families 
participating in such a trade.
    (iii) A manufacturer may only trade credits that it has generated 
pursuant to paragraph (o)(4) of this section or acquired from another 
party.
    (p) Reporting and recordkeeping. Keep records and submit information 
for demonstrating compliance with the fleet average cold temperature 
NMHC standard as described in Sec.86.1862-04.

FR 23736, Apr. 28, 2014]



Sec.86.1865-12  How to comply with the fleet average CO2 standards.

    (a) Applicability. (1) Unless otherwise exempted under the 
provisions of paragraph (d) of this section, CO2 fleet 
average exhaust emission standards of this subpart apply to:
    (i) 2012 and later model year passenger automobiles and light 
trucks.
    (ii) Heavy-duty vehicles subject to standards under Sec.86.1819.
    (iii) Vehicles imported by ICIs as defined in 40 CFR 85.1502.

[[Page 1101]]

    (2) The terms ``passenger automobile'' and ``light truck'' as used 
in this section have the meanings given in Sec.86.1818-12.
    (b) Useful life requirements. Full useful life requirements for 
CO2 standards are defined in Sec. Sec.86.1818 and 86.1819. 
There is not an intermediate useful life standard for CO2 
emissions.
    (c) Altitude. Greenhouse gas emission standards apply for testing at 
both low-altitude conditions and at high-altitude conditions, as 
described in Sec. Sec.86.1818 and 86.1819.
    (d) Small volume manufacturer certification procedures. (1) 
Passenger automobiles and light trucks. Certification procedures for 
small volume manufacturers are provided in Sec.86.1838. Small 
businesses meeting certain criteria may be exempted from the greenhouse 
gas emission standards in Sec.86.1818 according to the provisions of 
Sec.86.1801-12(j) or (k).
    (2) Heavy-duty vehicles. HDV manufacturers that qualify as small 
businesses are not subject to the Phase 1 greenhouse gas standards of 
this subpart as specified in Sec.86.1819-14(k)(5).
    (e) CO2 fleet average exhaust emission standards. The fleet average 
standards referred to in this section are the corporate fleet average 
CO2 standards for passenger automobiles and light trucks set 
forth in Sec.86.1818-12(c) and (e), and for HDV in Sec.86.1819. Each 
manufacturer must comply with the applicable CO2 fleet 
average standard on a production-weighted average basis, for each 
separate averaging set, at the end of each model year, using the 
procedure described in paragraph (j) of this section. The fleet average 
CO2 standards applicable in a given model year are calculated 
separately for passenger automobiles and light trucks for each 
manufacturer and each model year according to the provisions in Sec.
86.1818. Calculate the HDV fleet average CO2 standard in a 
given model year as described in Sec.86.1819-14(a).
    (f) In-use CO2 standards. In-use CO2 exhaust emission 
standards are provided in Sec.86.1818-12(d) for passenger automobiles 
and light trucks and in Sec.86.1819-14(b) for HDV.
    (g) Durability procedures and method of determining deterioration 
factors (DFs). Deterioration factors for CO2 exhaust emission 
standards are provided in Sec.86.1823-08(m) for passenger automobiles 
and light trucks and in Sec.86.1819-14(d)(5) for HDV.
    (h) Vehicle test procedures. (1) The test procedures for 
demonstrating compliance with CO2 exhaust emission standards 
are described at Sec.86.101 and 40 CFR part 600, subpart B.
    (2) Testing to determine compliance with CO2 exhaust 
emission standards must be on a loaded vehicle weight (LVW) basis for 
passenger automobiles and light trucks (including MDPV), and on an 
adjusted loaded vehicle weight (ALVW) basis for non-MDPV heavy-duty 
vehicles.
    (3) Testing for the purpose of providing certification data is 
required only at low-altitude conditions. If hardware and software 
emission control strategies used during low-altitude condition testing 
are not used similarly across all altitudes for in-use operation, the 
manufacturer must include a statement in the application for 
certification, in accordance with Sec.86.1844-01(d)(11), stating what 
the different strategies are and why they are used.
    (i) Calculating fleet average carbon-related exhaust emissions for 
passenger automobiles and light trucks. (1) Manufacturers must compute 
separate production-weighted fleet average carbon-related exhaust 
emissions at the end of the model year for passenger automobiles and 
light trucks, using actual production, where production means vehicles 
produced and delivered for sale, and certifying model types to standards 
as defined in Sec.86.1818-12. The model type carbon-related exhaust 
emission results determined according to 40 CFR part 600, subpart F (in 
units of grams per mile rounded to the nearest whole number) become the 
certification standard for each model type.
    (2) Manufacturers must separately calculate production-weighted 
fleet average carbon-related exhaust emissions levels for the following 
averaging sets according to the provisions of 40 CFR part 600, subpart 
F:
    (i) Passenger automobiles subject to the fleet average 
CO2 standards specified in Sec.86.1818-12(c)(2);

[[Page 1102]]

    (ii) Light trucks subject to the fleet average CO2 
standards specified in Sec.86.1818-12(c)(3);
    (iii) Passenger automobiles subject to the Temporary Leadtime 
Allowance Alternative Standards specified in Sec.86.1818-12(e), if 
applicable; and
    (iv) Light trucks subject to the Temporary Leadtime Allowance 
Alternative Standards specified in Sec.86.1818-12(e), if applicable.
    (j) Certification compliance and enforcement requirements for CO 2 
exhaust emission standards.
    (1) Compliance and enforcement requirements are provided in this 
section and Sec.86.1848-10(c)(9).
    (2) The certificate issued for each test group requires all model 
types within that test group to meet the in-use emission standards to 
which each model type is certified. The in-use standards for passenger 
automobiles and light duty trucks (including MDPV) are described in 
Sec.86.1818-12(d). The in-use standards for non-MDPV heavy-duty 
vehicles are described in Sec.86.1819-14(b).
    (3) Each manufacturer must comply with the applicable CO2 
fleet average standard on a production-weighted average basis, at the 
end of each model year. Use the procedure described in paragraph (i) of 
this section for passenger automobiles and light trucks (including 
MDPV). Use the procedure described in Sec.86.1819-14(d)(9)(iv) for 
non-MDPV heavy-duty vehicles.
    (4) Each manufacturer must comply on an annual basis with the fleet 
average standards as follows:
    (i) Manufacturers must report in their annual reports to the Agency 
that they met the relevant corporate average standard by showing that 
the applicable production-weighted average CO2 emission 
levels are at or below the applicable fleet average standards; or
    (ii) If the production-weighted average is above the applicable 
fleet average standard, manufacturers must obtain and apply sufficient 
CO2 credits as authorized under paragraph (k)(8) of this 
section. A manufacturer must show that they have offset any exceedance 
of the corporate average standard via the use of credits. Manufacturers 
must also include their credit balances or deficits in their annual 
report to the Agency.
    (iii) If a manufacturer fails to meet the corporate average 
CO2 standard for four consecutive years, the vehicles causing 
the corporate average exceedance will be considered not covered by the 
certificate of conformity (see paragraph (k)(8) of this section). A 
manufacturer will be subject to penalties on an individual-vehicle basis 
for sale of vehicles not covered by a certificate.
    (iv) EPA will review each manufacturer's production to designate the 
vehicles that caused the exceedance of the corporate average standard. 
EPA will designate as nonconforming those vehicles in test groups with 
the highest certification emission values first, continuing until 
reaching a number of vehicles equal to the calculated number of 
noncomplying vehicles as determined in paragraph (k)(8) of this section. 
In a group where only a portion of vehicles would be deemed 
nonconforming, EPA will determine the actual nonconforming vehicles by 
counting backwards from the last vehicle produced in that test group. 
Manufacturers will be liable for penalties for each vehicle sold that is 
not covered by a certificate.
    (k) Requirements for the CO2 averaging, banking and trading (ABT) 
program. (1) A manufacturer whose CO2 fleet average emissions 
exceed the applicable standard must complete the calculation in 
paragraph (k)(4) of this section to determine the size of its 
CO2 deficit. A manufacturer whose CO2 fleet 
average emissions are less than the applicable standard may complete the 
calculation in paragraph (k)(4) of this section to generate 
CO2 credits. In either case, the number of credits or debits 
must be rounded to the nearest whole number.
    (2) There are no property rights associated with CO2 
credits generated under this subpart. Credits are a limited 
authorization to emit the designated amount of emissions. Nothing in 
this part or any other provision of law should be construed to limit 
EPA's authority to terminate or limit this authorization through a 
rulemaking.
    (3) Each manufacturer must comply with the reporting and 
recordkeeping requirements of paragraph (l) of this section for 
CO2 credits, including early

[[Page 1103]]

credits. The averaging, banking and trading program is enforceable 
through the certificate of conformity that allows the manufacturer to 
introduce any regulated vehicles into U.S. commerce.
    (4) Credits are earned on the last day of the model year. 
Manufacturers must calculate, for a given model year and separately for 
passenger automobiles, light trucks, and heavy-duty vehicles, the number 
of credits or debits it has generated according to the following 
equation rounded to the nearest megagram:

CO2 Credits or Debits (Mg) = [(CO2 Standard - Manufacturer's Production-
Weighted Fleet Average CO2 Emissions) x (Total Number of Vehicles 
Produced) x (Mileage)] / 1,000,000

Where:

CO2 Standard = the applicable standard for the model year as determined 
          in Sec.86.1818 or Sec.86.1819;
Manufacturer's Production-Weighted Fleet Average CO2 Emissions = average 
          calculated according to paragraph (i) of this section;
Total Number of Vehicles Produced = the number of vehicles domestically 
          produced plus those imported as defined in Sec.600.511-08 of 
          this chapter; and
Mileage = useful life value (in miles) for HDV, and vehicle lifetime 
          miles of 195,264 for passenger automobiles and 225,865 for 
          light trucks.

    (5) Determine total HDV debits and credits for a model year as 
described in Sec.86.1819-14(d)(6). Determine total passenger car and 
light truck debits and credits for a model year as described in this 
paragraph (k)(5). Total credits or debits generated in a model year, 
maintained and reported separately for passenger automobiles and light 
trucks, shall be the sum of the credits or debits calculated in 
paragraph (k)(4) of this section and any of the following credits, if 
applicable, minus any CO2-equivalent debits for 
N2O and/or CH4 calculated according to the 
provisions of Sec.86.1818-12(f)(4):
    (i) Air conditioning leakage credits earned according to the 
provisions of Sec.86.1867-12(b).
    (ii) Air conditioning efficiency credits earned according to the 
provisions of Sec.86.1868-12(c).
    (iii) Off-cycle technology credits earned according to the 
provisions of Sec.86.1869-12(d).
    (iv) Full size pickup truck credits earned according to the 
provisions of Sec.86.1870-12(c).
    (v) Advanced technology vehicle credits earned according to the 
provisions of Sec.86.1866-12(b)(3).
    (vi) CO2-equivalent debits for N2O and/or 
CH4 accumulated according to the provisions of Sec.86.1818-
12(f)(4).
    (6) Unused CO2 credits generally retain their full value 
through five model years after the model year in which they were 
generated. Credits remaining at the end of the fifth model year after 
the model year in which they were generated may not be used to 
demonstrate compliance for later model years. The following particular 
provisions apply for passenger cars and light trucks:
    (i) Unused CO2 credits from the 2009 model year shall 
retain their full value through the 2014 model year. Credits from the 
2009 model year that remain at the end of the 2014 model year may not be 
used to demonstrate compliance for later model years.
    (ii) Unused CO2 credits from the 2010 through 2015 model 
years shall retain their full value through the 2021 model year. Credits 
remaining from these model years at the end of the 2021 model year may 
not be used to demonstrate compliance for later model years.
    (7) Credits may be used as follows:
    (i) Credits generated and calculated according to the method in 
paragraphs (k)(4) and (5) of this section may not be used to offset 
deficits other than those deficits accrued within the respective 
averaging set, except that credits may be transferred between the 
passenger automobile and light truck fleets of a given manufacturer. 
Credits may be banked and used in a future model year in which a 
manufacturer's average CO2 level exceeds the applicable 
standard. Credits may also be traded to another manufacturer according 
to the provisions in paragraph (k)(8) of this section. Before trading or 
carrying over credits to the next model year, a manufacturer must apply 
available credits to offset any deficit, where the deadline to offset 
that credit deficit has not yet passed. This paragraph (k)(7)(i) applies 
for MDPV, but not for other HDV.

[[Page 1104]]

    (ii) The use of credits shall not change Selective Enforcement 
Auditing or in-use testing failures from a failure to a non-failure. The 
enforcement of the averaging standard occurs through the vehicle's 
certificate of conformity as described in paragraph (k)(8) of this 
section. A manufacturer's certificate of conformity is conditioned upon 
compliance with the averaging provisions. The certificate will be void 
ab initio if a manufacturer fails to meet the corporate average standard 
and does not obtain appropriate credits to cover its shortfalls in that 
model year or subsequent model years (see deficit carry-forward 
provisions in paragraph (k)(8) of this section).
    (iii) The following provisions apply for passenger automobiles and 
light trucks under the Temporary Leadtime Allowance Alternative 
Standards:
    (A) Credits generated by vehicles subject to the fleet average 
CO2 standards specified in Sec.86.1818-12(c) may only be 
used to offset a deficit generated by vehicles subject to the Temporary 
Leadtime Allowance Alternative Standards specified in Sec.86.1818-
12(e).
    (B) Credits generated by a passenger automobile or light truck 
averaging set subject to the Temporary Leadtime Allowance Alternative 
Standards specified in Sec.86.1818-12(e)(4)(i) or (ii) may be used to 
offset a deficit generated by an averaging set subject to the Temporary 
Leadtime Allowance Alternative Standards through the 2015 model year, 
except that manufacturers qualifying under the provisions of Sec.
86.1818-12(e)(3) may use such credits to offset a deficit generated by 
an averaging set subject to the Temporary Leadtime Allowance Alternative 
Standards through the 2016 model year.
    (C) Credits generated by an averaging set subject to the Temporary 
Leadtime Allowance Alternative Standards specified in Sec.86.1818-
12(e)(4)(i) or (ii) of this section may not be used to offset a deficit 
generated by an averaging set subject to the fleet average 
CO2 standards specified in Sec.86.1818-12(c)(2) or (3) or 
otherwise transferred to an averaging set subject to the fleet average 
CO2 standards specified in Sec.86.1818-12(c)(2) or (3).
    (D) Credits generated by vehicles subject to the Temporary Leadtime 
Allowance Alternative Standards specified in Sec.86.1818-12(e)(4)(i) 
or (ii) may be banked for use in a future model year (to offset a 
deficit generated by an averaging set subject to the Temporary Leadtime 
Allowance Alternative Standards). All such credits may not be used to 
demonstrate compliance for model year 2016 and later vehicles, except 
that manufacturers qualifying under the provisions of Sec.86.1818-
12(e)(3) may use such credits to offset a deficit generated by an 
averaging set subject to the Temporary Leadtime Allowance Alternative 
Standards through the 2016 model year.
    (E) A manufacturer with any vehicles subject to the Temporary 
Leadtime Allowance Alternative Standards specified in Sec.86.1818-
12(e)(4)(i) or (ii) of this section in a model year in which that 
manufacturer also generates credits with vehicles subject to the fleet 
average CO2 standards specified in Sec.86.1818-12(c) may 
not trade or bank credits earned against the fleet average standards in 
Sec.86.1818-12(c) for use in a future model year.
    (iv) Credits generated in the 2017 through 2020 model years under 
the provisions of Sec.86.1818-12(e)(3)(ii) may not be traded or 
otherwise provided to another manufacturer.
    (v) Credits generated under any alternative fleet average standards 
approved under Sec.86.1818-12(g) may not be traded or otherwise 
provided to another manufacturer.
    (8) The following provisions apply if a manufacturer calculates that 
it has negative credits (also called ``debits'' or a ``credit deficit'') 
for a given model year:
    (i) The manufacturer may carry the credit deficit forward into the 
next three model years. Such a carry-forward may only occur after the 
manufacturer exhausts any supply of banked credits. The deficit must be 
covered with an appropriate number of credits that the manufacturer 
generates or purchases by the end of the third model year. Any remaining 
deficit is subject to a voiding of the certificate ab initio, as 
described in this paragraph (k)(8). Manufacturers are not permitted to 
have a credit deficit for four consecutive years.

[[Page 1105]]

    (ii) If the credit deficit is not offset within the specified time 
period, the number of vehicles not meeting the fleet average 
CO2 standards (and therefore not covered by the certificate) 
must be calculated.
    (A) Determine the negative credits for the noncompliant vehicle 
category by multiplying the total megagram deficit by 1,000,000 and then 
dividing by the mileage specified in paragraph (k)(4) of this section.
    (B) Divide the result by the fleet average standard applicable to 
the model year in which the debits were first incurred and round to the 
nearest whole number to determine the number of vehicles not meeting the 
fleet average CO2 standards.
    (iii) EPA will determine the vehicles not covered by a certificate 
because the condition on the certificate was not satisfied by 
designating vehicles in those test groups with the highest carbon-
related exhaust emission values first and continuing until reaching a 
number of vehicles equal to the calculated number of non-complying 
vehicles as determined in this paragraph (k)(8). The same approach 
applies for HDV, except that EPA will make these designations by ranking 
test groups based on CO2 emission values. If these 
calculations determines that only a portion of vehicles in a test group 
contribute to the debit situation, then EPA will designate actual 
vehicles in that test group as not covered by the certificate, starting 
with the last vehicle produced and counting backwards.
    (iv)(A) If a manufacturer ceases production of passenger 
automobiles, light trucks, or heavy-duty vehicles, the manufacturer 
continues to be responsible for offsetting any debits outstanding within 
the required time period. Any failure to offset the debits will be 
considered a violation of paragraph (k)(8)(i) of this section and may 
subject the manufacturer to an enforcement action for sale of vehicles 
not covered by a certificate, pursuant to paragraphs (k)(8)(ii) and 
(iii) of this section.
    (B) If a manufacturer is purchased by, merges with, or otherwise 
combines with another manufacturer, the controlling entity is 
responsible for offsetting any debits outstanding within the required 
time period. Any failure to offset the debits will be considered a 
violation of paragraph (k)(8)(i) of this section and may subject the 
manufacturer to an enforcement action for sale of vehicles not covered 
by a certificate, pursuant to paragraphs (k)(8)(ii) and (iii) of this 
section.
    (v) For purposes of calculating the statute of limitations, a 
violation of the requirements of paragraph (k)(8)(i) of this section, a 
failure to satisfy the conditions upon which a certificate(s) was issued 
and hence a sale of vehicles not covered by the certificate, all occur 
upon the expiration of the deadline for offsetting debits specified in 
paragraph (k)(8)(i) of this section.
    (9) The following provisions apply to CO2 credit trading:
    (i) EPA may reject CO2 credit trades if the involved 
manufacturers fail to submit the credit trade notification in the annual 
report.
    (ii) A manufacturer may not sell credits that are no longer valid 
for demonstrating compliance based on the model years of the subject 
vehicles, as specified in paragraph (k)(6) of this section.
    (iii) In the event of a negative credit balance resulting from a 
transaction, both the buyer and seller are liable for the credit 
shortfall. EPA may void ab initio the certificates of conformity of all 
test groups that generate or use credits in such a trade.
    (iv)(A) If a manufacturer trades a credit that it has not generated 
pursuant to this paragraph (k) or acquired from another party, the 
manufacturer will be considered to have generated a debit in the model 
year that the manufacturer traded the credit. The manufacturer must 
offset such debits by the deadline for the annual report for that same 
model year.
    (B) Failure to offset the debits within the required time period 
will be considered a failure to satisfy the conditions upon which the 
certificate(s) was issued and will be addressed pursuant to paragraph 
(k)(8) of this section.
    (v) A manufacturer may only trade credits that it has generated 
pursuant to paragraphs (k)(4) and (5) of this section or acquired from 
another party.

Sec.86.1866-12  CO [bdi2] credits for advanced technology vehicles.

    This section describes how to apply CO2 credits for 
advanced technology passenger automobiles and light trucks (including 
MDPV). This section does not apply for heavy-duty vehicles that are not 
MDPV.
    (a) Electric vehicles, plug-in hybrid electric vehicles, and fuel 
cell vehicles, as those terms are defined in Sec.86.1803-01, that are 
certified and produced for U.S. sale, where ``U.S.'' means the states 
and territories of the United States, in the 2012 through 2025 model 
years may use a value of zero (0) grams/mile of CO2 to 
represent the proportion of electric operation of a vehicle that is 
derived from electricity that is generated from sources that are not 
onboard the vehicle, as specified by this paragraph (a).
    (1) Model years 2012 through 2016: The use of zero (0) grams/mile 
CO2 is limited to the first 200,000 combined electric 
vehicles, plug-in hybrid electric vehicles, and fuel cell vehicles 
produced for U.S. sale, where ``U.S.'' means the states and territories 
of the United States, in the 2012 through 2016 model years, except that 
a manufacturer that produces 25,000 or more such vehicles for U.S. sale 
in the 2012 model year shall be subject to a limitation on the use of 
zero (0) grams/mile CO2 to

[[Page 1108]]

the first 300,000 combined electric vehicles, plug-in hybrid electric 
vehicles, and fuel cell vehicles produced and delivered for sale by a 
manufacturer in the 2012 through 2016 model years.
    (2) Model years 2017 through 2026: For electric vehicles, plug-in 
hybrid electric vehicles, and fuel cell vehicles produced for U.S. sale, 
where ``U.S.'' means the states and territories of the United States, in 
the 2017 through 2026 model years, such use of zero (0) grams/mile 
CO2 is unrestricted.
    (b) For electric vehicles, plug-in hybrid electric vehicles, fuel 
cell vehicles, dedicated natural gas vehicles, and dual-fuel natural gas 
vehicles as those terms are defined in Sec.86.1803-01, that are 
certified and produced for U.S. sale in the specified model years and 
that meet the additional specifications in this section, the 
manufacturer may use the production multipliers in this paragraph (b) 
when determining additional credits for advanced technology vehicles. 
Full size pickup trucks eligible for and using a production multiplier 
are not eligible for the performance-based credits described in Sec.
86.1870-12(b).
    (1) The production multipliers, by model year, for model year 2017 
through 2021 electric vehicles and fuel cell vehicles are as follows:

------------------------------------------------------------------------
                                                            Production
                       Model year                           multiplier
------------------------------------------------------------------------
2017....................................................             2.0
2018....................................................             2.0
2019....................................................             2.0
2020....................................................            1.75
2021....................................................             1.5
------------------------------------------------------------------------

    (2)(i) The production multipliers, by model year, for model year 
2017 through 2021 plug-in hybrid electric vehicles and model year 2017 
through 2026 dedicated natural gas vehicles and dual-fuel natural gas 
vehicles are as follows:

------------------------------------------------------------------------
                                                            Production
                       Model year                           multiplier
------------------------------------------------------------------------
2017....................................................             1.6
2018....................................................             1.6
2019....................................................             1.6
2020....................................................            1.45
2021....................................................             1.3
2022-2026 (dedicated and dual fuel natural gas vehicles              2.0
 only)..................................................
------------------------------------------------------------------------

    (ii) The minimum all-electric driving range that a plug-in hybrid 
electric vehicle must have in order to qualify for use of a production 
multiplier is 10.2 miles on its nominal storage capacity of electricity 
when operated on the highway fuel economy test cycle. Alternatively, a 
plug-in hybrid electric vehicle may qualify for use of a production 
multiplier by having an equivalent all-electric driving range greater 
than or equal to 10.2 miles during its actual charge-depleting range as 
measured on the highway fuel economy test cycle and tested according to 
the requirements of SAE J1711, Recommended Practice for Measuring the 
Exhaust Emissions and Fuel Economy of Hybrid-Electric Vehicles, 
Including Plug-In Hybrid Vehicles (incorporated by reference in Sec.
86.1). The equivalent all-electric range of a PHEV is determined from 
the following formula:

EAER = RCDA x ((CO2CS - CO2CD/
CO2CS))

Where:

EAER = the equivalent all-electric range attributed to charge-depleting 
          operation of a plug-in hybrid electric vehicle on the highway 
          fuel economy test cycle.
RCDA = The actual charge-depleting range determined according 
          to SAE J1711, Recommended Practice for Measuring the Exhaust 
          Emissions and Fuel Economy of Hybrid-Electric Vehicles, 
          Including Plug-In Hybrid Vehicles (incorporated by reference 
          in Sec.86.1).
CO2CS = The charge-sustaining CO2 emissions in 
          grams per mile on the highway fuel economy test determined 
          according to SAE J1711, Recommended Practice for Measuring the 
          Exhaust Emissions and Fuel Economy of Hybrid-Electric 
          Vehicles, Including Plug-In Hybrid Vehicles (incorporated by 
          reference in Sec.86.1).
CO2CD = The charge-depleting CO2 emissions in 
          grams per mile on the highway fuel economy test determined 
          according to SAE J1711, Recommended Practice for Measuring the 
          Exhaust Emissions and Fuel Economy of Hybrid-Electric 
          Vehicles, Including Plug-In Hybrid Vehicles (incorporated by 
          reference in Sec.86.1).

    (3) The actual production of qualifying vehicles may be multiplied 
by the applicable value according to the model year, and the result, 
rounded to the nearest whole number, may be used to represent the 
production of qualifying vehicles when calculating average carbon-
related exhaust emissions under Sec.600.512 of this chapter.

[[Page 1109]]

    (c) Calculating multiplier-based credits for advanced technology 
vehicles: This paragraph (c) describes the method for calculating 
credits using the production multipliers in paragraph (b) of this 
section. Production multipliers must be used according to this paragraph 
(c) and must not be used in calculating fleet average carbon-related 
exhaust emissions under 40 CFR part 600 or Sec.86.1865-12(i), or in 
any elements of the equation used for the calculation of CO2 
credits or debits in Sec.86.1865-12(k)(4). Calculate credits for 
advanced technology vehicles for a given model year, and separately for 
passenger automobiles and light trucks, using the following equation, 
subtracting the credits calculated for the base fleet from the credits 
calculated for the fleet with multipliers applied. No credits are earned 
if the result is a negative value. All values expressed in megagrams 
shall be rounded to the nearest whole number.

Credits [Mg] = [Creditsadj]-[Creditsbase]

    (1) For model year 2017-2021 multipliers, determine adjusted fleet 
credits (Creditsadj) in megagrams using one of the following 
methods, where the resulting Creditsadj is rounded to the 
nearest whole number. Use the method that returns the highest total 
megagrams. For 2022 and later model years, determine adjusted fleet 
credits (Creditsadj) in megagrams using only Method 1 in 
paragraph (c)(1)(i) of this section, where the resulting 
Creditsadj is rounded to the nearest whole number. Note that 
the adjusted CO2 standard (Sadj) and the adjusted 
fleet average carbon-related exhaust emissions (Eadj) are 
determined solely for the purpose of calculating advanced technology 
vehicle credits in this section; the official CO2 standard 
applicable to the fleet will continue to be the value calculated and 
rounded according to Sec.86.1818-12(c), and the official fleet average 
carbon-related exhaust emissions applicable to the fleet will continue 
to be the value calculated and rounded according to 40 CFR 600.510-
12(j). In addition, note that the rounding requirements in this section 
differ from those specified for the official fleet standards calculated 
under Sec.86.1818-12 and for the official fleet average carbon-related 
exhaust emissions calculated under 40 CFR 600.510-12.
    (i) Method 1: All values that determine fleet credits are adjusted 
using the applicable multipliers.
[GRAPHIC] [TIFF OMITTED] TR23AP20.028

Where:

Sadj = adjusted CO2 standard calculated according 
          to the method described in Sec.86.1818-12(c), except that 
          the actual production of qualifying vehicles under this 
          section shall be multiplied by the applicable production 
          multiplier, and no rounding shall be applied to the result.
Eadj = adjusted production-weighted fleet average carbon-
          related exhaust emissions calculated according to the method 
          described in 40 CFR 600.510-12(j), except that the actual 
          production of qualifying vehicles under this section shall be 
          multiplied by the applicable production multiplier, and no 
          rounding shall be applied to the result.
Padj = total adjusted production of passenger automobiles or 
          light trucks, except that the actual production of qualifying 
          vehicles under this section shall be multiplied by the 
          applicable production multiplier, and no rounding shall be 
          applied to the result.
VLM = vehicle lifetime miles, which for passenger automobiles shall be 
          195,264 and for light trucks shall be 225,865.

    (ii) Method 2: Multipliers are applied only to calculation of the 
fleet average carbon-related exhaust emissions.

[[Page 1110]]

[GRAPHIC] [TIFF OMITTED] TR23AP20.029

Sbase = CO2 standard calculated according to the 
          method described in Sec.86.1818-12(c), except that no 
          rounding shall be applied to the result.
Eadj = adjusted production-weighted fleet average carbon-
          related exhaust emissions calculated according to the method 
          described in 40 CFR 600.510-12(j), except that the actual 
          production of qualifying vehicles under this section shall be 
          multiplied by the applicable production multiplier, and no 
          rounding shall be applied to the result.
Pbase = total production of passenger automobiles or light 
          trucks.
VLM = vehicle lifetime miles, which for passenger automobiles shall be 
          195,264 and for light trucks shall be 225,865.

    (2) Determine base fleet credits in megagrams using the following 
equation and rounding the result to the nearest whole number. Do not 
adjust any production volume values with a multiplier. Note that the 
CO2 standard (Sbase) and the fleet average carbon-
related exhaust emissions (Ebase) are determined solely for 
the purpose of calculating advanced technology vehicle credits in this 
section and do not replace the official fleet values; the official 
CO2 standard applicable to the fleet will continue to be the 
value calculated and rounded according to Sec.86.1818-12(c), and the 
official fleet average carbon-related exhaust emissions applicable to 
the fleet will continue to be the value calculated and rounded according 
to 40 CFR 600.510-12(j). In addition, note that the rounding 
requirements in this section differ from those specified for the 
official fleet standards calculated under Sec.86.1818-12 and for the 
official fleet average carbon-related exhaust emissions calculated under 
40 CFR 600.510-12.

Ebase = production-weighted fleet average carbon-related 
          exhaust emissions calculated according to the method described 
          in 40 CFR 600.510-12(j), except that no rounding shall be

Sec.86.1867-12  CO [bdi2] credits for reducing leakage of air 
conditioning refrigerant.

    Manufacturers may generate credits applicable to the CO2 
fleet average program described in Sec.86.1865-12 by implementing 
specific air conditioning system technologies designed to reduce air 
conditioning refrigerant leakage over the useful life of their passenger 
automobiles and/or light trucks (including MDPV); only the provisions of 
paragraph (a) of this section apply for non-MDPV heavy-duty vehicles. 
Credits shall be calculated according to this section for each air 
conditioning system that the manufacturer is using to generate 
CO2 credits. Manufacturers may also generate early air 
conditioning refrigerant leakage credits under this section for the 2009 
through 2011 model years according to the provisions of Sec.86.1871-
12(b).
    (a) The manufacturer shall calculate an annual rate of refrigerant 
leakage from an air conditioning system in grams per year according to 
the procedures specified in SAE J2727 (incorporated by reference in 
Sec.86.1). In doing

[[Page 1111]]

so, the refrigerant permeation rates for hoses shall be determined using 
the procedures specified in SAE J2064 (incorporated by reference in 
Sec.86.1) The annual rate of refrigerant leakage from an air 
conditioning system shall be rounded to the nearest tenth of a gram per 
year. The procedures of SAE J2727 may be used to determine leakage rates 
for HFC-134a and HFO-1234yf; manufacturers should contact EPA regarding 
procedures for other refrigerants. The annual rate of refrigerant 
leakage from an air conditioning system shall be rounded to the nearest 
tenth of a gram per year.
    (b) The CO2-equivalent gram per mile leakage reduction 
used to calculate the total leakage credits generated by an air 
conditioning system shall be determined according to this paragraph (b), 
separately for passenger automobiles and light trucks, and rounded to 
the nearest tenth of a gram per mile:
    (1) Passenger automobile leakage credit for an air conditioning 
system:
[GRAPHIC] [TIFF OMITTED] TR15OC12.038

Where:

    MaxCredit is 12.6 (grams CO2-equivalent/mile) for air 
conditioning systems using HFC-134a, and 13.8 (grams CO2-
equivalent/mile) for air conditioning systems using a refrigerant with a 
lower global warming potential.
    LeakScore means the annual refrigerant leakage rate determined 
according to the procedures in SAE J2727 (incorporated by reference in 
Sec.86.1), where the refrigerant permeation rates for hoses shall be 
determined using the procedures specified in SAE J2064 (incorporated by 
reference in Sec.86.1). If the calculated rate is less than 8.3 grams/
year (or 4.1 grams/year for systems using only electric compressors), 
the rate for the purpose of this formula shall be 8.3 grams/year (or 4.1 
grams/year for systems using only electric compressors).
    GWPREF means the global warming potential of the 
refrigerant as indicated in paragraph (e) of this section or as 
otherwise determined by the Administrator;
    HiLeakDis means the high leak disincentive, which is zero for model 
years 2012 through 2016, and for 2017 and later model years is 
determined using the following equation, except that if 
GWPREF is greater than 150 or if the calculated result of the 
equation is less than zero, HiLeakDis shall be set equal to zero, or if 
the calculated result of the equation is greater than 1.8 g/mi, 
HiLeakDis shall be set to 1.8 g/mi:
[GRAPHIC] [TIFF OMITTED] TR15OC12.039


Where,

LeakThreshold = 11.0 for air conditioning systems with a refrigerant 
          capacity less than or equal to 733 grams; or
LeakThreshold = [Refrigerant Capacity x 0.015] for air conditioning 
          systems with a refrigerant capacity greater than 733 grams, 
          where RefrigerantCapacity is the maximum refrigerant capacity 
          specified for the air conditioning system, in grams.

Where:

MaxCredit is 15.6 (grams CO2-equivalent/mile) for air 
          conditioning systems using HFC-134a, and 17.2 (grams 
          CO2-equivalent/mile) for air conditioning systems 
          using a refrigerant with a lower global warming potential.

[[Page 1112]]

LeakScore means the annual refrigerant leakage rate determined according 
          to the provisions of SAE J2727 (incorporated by reference in 
          Sec.86.1),, where the refrigerant permeation rates for hoses 
          shall be determined using the procedures specified in SAE 
          J2064 (incorporated by reference in Sec.86.1). If the 
          calculated rate is less than 10.4 grams/year (or 5.2 grams/
          year for systems using only electric compressors), the rate 
          for the purpose of this formula shall be 10.4 grams/year (or 
          5.2 grams/year for systems using only electric compressors).
GWPREF means the global warming potential of the refrigerant 
          as indicated in paragraph (e) of this section or as otherwise 
          determined by the Administrator;
HiLeakDis means the high leak disincentive, which is zero for model 
          years 2012 through 2016, and for 2017 and later model years is 
          determined using the following equation, except that if 
          GWPREF is greater than 150 or if the calculated 
          result of the equation is less than zero, HiLeakDis shall be 
          set equal to zero, or if the calculated result of the equation 
          is greater than 2.1 g/mi, HiLeakDis shall be set to 2.1 g/mi:
          [GRAPHIC] [TIFF OMITTED] TR15OC12.041
          
Where:

LeakThreshold = 11.0 for air conditioning systems with a refrigerant 
          capacity less than or equal to 733 grams; or
LeakThreshold = [Refrigerant Capacity x 0.015] for air conditioning 
          systems with a refrigerant capacity greater than 733 grams, 
          where RefrigerantCapacity is the maximum refrigerant capacity 
          specified for the air conditioning system, in grams.

    (c) The total leakage reduction credits generated by the air 
conditioning system shall be calculated separately for passenger 
automobiles and light trucks according to the following formula:

Total Credits (Megagrams) = (Leakage x Production x VLM) / 1,000,000

Where:

Leakage = the CO2-equivalent leakage credit value in grams 
          per mile determined in paragraph (b)(1) or (b)(2) of this 
          section, whichever is applicable.

Production = The total number of passenger automobiles or light trucks, 
          whichever is applicable, produced with the air conditioning

nearest whole number, shall be included in the manufacturer's credit/
debit totals calculated in Sec.86.1865-12(k)(5).
    (e) The following values for refrigerant global warming potential 
(GWPREF), or alternative values as determined by the 
Administrator, shall be used in the calculations of this section. The 
Administrator will determine values for refrigerants not included in 
this paragraph (e) upon request by a manufacturer.
    (1) For HFC-134a, GWPREF = 1430;
    (2) For HFC-152a, GWPREF = 124;
    (3) For HFO-1234yf, GWPREF = 4;
    (4) For CO2, GWPREF = 1.

Sec.86.1868-12  CO2 credits for improving the efficiency of air 
conditioning systems.

    Manufacturers may generate credits applicable to the CO2 
fleet average program described in Sec.86.1865-12 by implementing 
specific air conditioning system technologies designed to reduce air 
conditioning-related CO2 emissions over the useful life of 
their passenger automobiles and/or light trucks (including MDPV). The 
provisions of this section do not apply for non-MDPV heavy-duty 
vehicles. Credits shall be calculated according to this section for each 
air conditioning system that the manufacturer is using to generate 
CO2 credits. Manufacturers may also generate early air 
conditioning efficiency credits under this section for the 2009 through 
2011 model years according to the provisions of Sec.86.1871-12(b). For

[[Page 1113]]

model years 2012 and 2013 the manufacturer may determine air 
conditioning efficiency credits using the requirements in paragraphs (a) 
through (d) of this section. For model years 2014 through 2016 the 
eligibility requirements specified in either paragraph (e) or (f) of 
this section must be met before an air conditioning system is allowed to 
generate credits. For model years 2017 through 2019 the eligibility 
requirements specified in paragraph (f) of this section must be met 
before an air conditioning system is allowed to generate credits. For 
model years 2020 and later the eligibility requirements specified in 
paragraph (g) of this section must be met before an air conditioning 
system is allowed to generate credits.

    (b) Air conditioning efficiency credits are determined on an air 
conditioning system basis. For each air conditioning system that is 
eligible for a credit based on the use of one or more of the items 
listed in paragraph (a) of this section, the total credit value is the 
sum of the gram per mile values for the appropriate model year listed in 
paragraph (a) of this section for each item that applies to the air 
conditioning system.
    (1) In the 2012 through 2016 model years the total credit value for 
an air conditioning system for passenger automobiles or light trucks may 
not be greater than 5.7 grams per mile.
    (2) In the 2017 and later model years the total credit value for an 
air conditioning system may not be greater than 5.0 grams per mile for 
any passenger automobile or 7.2 grams per mile for any light truck.
    (c) The total efficiency credits generated by an air conditioning 
system shall be calculated separately for passenger automobiles and 
light trucks according to the following formula:

Total Credits (Megagrams) = (Credit x Production x VLM) / 1,000,000

Where:

Credit = the CO2 efficiency credit value in grams per mile 
          determined in paragraph (b) or (e) of this section, whichever 
          is applicable.
Production = The total number of passenger automobiles or light trucks, 
          whichever is applicable, produced with the air conditioning 
          system to which to the efficiency credit value from paragraph 
          (b) of this section applies.
VLM = vehicle lifetime miles, which for passenger automobiles shall be 
          195,264 and for light trucks shall be 225,865.

    (d) The results of paragraph (c) of this section, rounded to the 
nearest whole number, shall be included in the manufacturer's credit/
debit totals calculated in Sec.86.1865-12(k)(5).
    (e) For the 2014 through 2016 model years, manufacturers must 
validate air conditioning credits by using the Air Conditioning Idle 
Test Procedure according to the provisions of this paragraph (e) or, 
alternatively, by using the AC17 reporting requirements specified in 
paragraph (f) of this section. The Air Conditioning Idle Test Procedure 
is not applicable after the 2016 model year.
    (1) For each air conditioning system selected by the manufacturer to 
generate air conditioning efficiency credits, the manufacturer shall 
perform the Air Conditioning Idle Test Procedure specified in Sec.
86.165-12 of this part.
    (2) Using good engineering judgment, the manufacturer must select 
the vehicle configuration to be tested that is expected to result in the 
greatest increased CO2 emissions as a result of the operation 
of the air conditioning system for which efficiency credits are being 
sought. If the air conditioning system is being installed in passenger 
automobiles and light trucks, a separate determination of the quantity 
of credits for passenger automobiles and light trucks must be made, but 
only one test vehicle is required to represent the air conditioning 
system, provided it represents the worst-case impact of the system on 
CO2 emissions.
    (3) The manufacturer shall determine an idle test threshold (ITT) 
for the tested vehicle configuration. A comparison of this threshold 
value with the CO2 emissions increase recorded over the Air 
Conditioning Idle Test Procedure in Sec.86.165-12 determines the total

[[Page 1115]]

credits that may be generated by an air conditioning system. The 
manufacturer may choose one of the following idle test threshold (ITT) 
values for an air conditioning system:
    (i) 14.9 grams per minute; or
    (ii) The value determined from the following equation, rounded to 
the nearest tenth of a gram per minute:
[GRAPHIC] [TIFF OMITTED] TR15OC12.042

Where:

Displacement = the engine displacement of the test vehicle, expressed in 
          liters and rounded to the nearest one tenth of a liter.

    (4)(i) If the CO2 emissions value determined from the 
Idle Test Procedure in Sec.86.165-12 is less than or equal to the idle 
test threshold (ITT) determined in paragraph (e)(3) of this section, the 
total CO2 efficiency credit value (Credit) for use in 
paragraph (c) of this section shall be the applicable value determined 
in paragraph (b) of this section.
    (ii) If the CO2 emissions value determined from the Idle 
Test Procedure in Sec.86.165-12 is greater than the idle test 
threshold (ITT) determined in paragraph (e)(3) of this section, the 
total CO2 efficiency credit value (Credit) for use in 
paragraph (c) of this section shall be determined using the following 
formula:
[GRAPHIC] [TIFF OMITTED] TR15OC12.043

Where:

Credit = The CO2 efficiency credit value (Credit) that must 
          be used in paragraph (c) of this section to calculate the 
          total credits (in Megagrams) of air conditioning efficiency 
          credits;
TCV = The total CO2 efficiency credit value determined 
          according to paragraph (b) of this section; and
ITP = the increased CO2 emissions determined from the Idle 
          Test Procedure in Sec.86.165-14.
ITT = the idle test threshold determined in paragraph (e)(3) of this 
          section and rounded to the nearest one tenth of a gram per 
          minute:

    (iii) Air conditioning systems that record an increased 
CO2 emissions value on the Idle Test Procedure in Sec.
86.165-14 that is greater than or equal to the idle test threshold (ITT) 
determined in paragraph (e)(3) of this section plus 6.4 grams per minute 
are not eligible for an air conditioning efficiency credit.
    (5) Air conditioning systems with compressors that are solely 
powered by electricity shall submit Air Conditioning Idle Test Procedure 
data to be eligible to generate credits in the 2014 and later model 
years, but such systems are not required to meet a specific threshold to 
be eligible to generate such credits, as long as the engine remains off 
for a period of at least 2 cumulative minutes during the air 
conditioning on portion of the Idle Test Procedure in Sec.86.165-
12(d).
    (f) AC17 reporting requirements. Manufacturers may use the 
provisions of this paragraph (f) as an alternative to the use of the Air 
Conditioning Idle Test to demonstrate eligibility to generate air 
conditioning efficiency credits for the 2014 through 2016 model years. 
This paragraph (f) is required for the 2017 through 2019 model years.
    (1) The manufacturer shall perform the AC17 test specified in 40 CFR 
1066.845 on each unique air conditioning system design and vehicle 
platform combination (as those terms are defined in Sec.86.1803) for 
which the manufacturer intends to accrue air conditioning efficiency 
credits. The manufacturer must test at least one unique air conditioning 
system within each

[[Page 1116]]

vehicle platform in a model year, unless all unique air conditioning 
systems within a vehicle platform have been previously tested. A unique 
air conditioning system design is a system with unique or substantially 
different component designs or types and/or system control strategies 
(e.g., fixed displacement vs. variable displacement compressors, orifice 
tube vs. thermostatic expansion valve, single vs. dual evaporator, 
etc.). In the first year of such testing, the tested vehicle 
configuration shall be the highest production vehicle configuration 
within each platform. In subsequent model years the manufacturer must 
test other unique air conditioning systems within the vehicle platform, 
proceeding from the highest production untested system until all unique 
air conditioning systems within the platform have been tested, or until 
the vehicle platform experiences a major redesign. Whenever a new unique 
air conditioning system is tested, the highest production configuration 
using that system shall be the vehicle selected for testing. Air 
conditioning system designs which have similar cooling capacity, 
component types, and control strategies, yet differ in terms of 
compressor pulley ratios or condenser or evaporator surface areas will 
not be considered to be unique system designs. The test results from one 
unique system design may represent all variants of that design. 
Manufacturers must use good engineering judgment to identify the unique 
air conditioning system designs which will require AC17 testing in 
subsequent model years. Results must be reported separately for all four 
phases (two phases with air conditioning off and two phases with air 
conditioning on) of the test to the Environmental Protection Agency, and 
the results of the calculations required in 40 CFR 1066.845 must also be 
reported. In each subsequent model year additional air conditioning 
system designs, if such systems exist, within a vehicle platform that is 
generating air conditioning credits must be tested using the AC17 
procedure. When all unique air conditioning system designs within a 
platform have been tested, no additional testing is required within that 
platform, and credits may be carried over to subsequent model years 
until there is a significant change in the platform design, at which 
point a new sequence of testing must be initiated. No more than one 
vehicle from each credit-generating platform is required to be tested in 
each model year.
    (2) The manufacturer shall also report the following information for 
each vehicle tested: the vehicle class, model type, curb weight, engine 
displacement, transmission class and configuration, interior volume, 
climate control system type and characteristics, refrigerant used, 
compressor type, and evaporator/condenser characteristics.
    (g) AC17 validation testing and reporting requirements. For the 2020 
and later model years, manufacturers must validate air conditioning 
credits by using the AC17 Test Procedure according to the provisions of 
this paragraph (g).
    (1) For each air conditioning system (as defined in Sec.86.1803) 
selected by the manufacturer to generate air conditioning efficiency 
credits, the manufacturer shall perform the AC17 Air Conditioning 
Efficiency Test Procedure specified in 40 CFR 1066.845, according to the 
requirements of this paragraph (g).
    (2) Complete the following testing and calculations:
    (i) Perform the AC17 test on a vehicle that incorporates the air 
conditioning system with the credit-generating technologies.
    (ii) Perform the AC17 test on a vehicle which does not incorporate 
the credit-generating technologies. The tested vehicle must be similar 
to the vehicle tested under paragraph (g)(2)(i) of this section and 
selected using good engineering judgment. The tested vehicle may be from 
an earlier design generation. If the manufacturer cannot identify an 
appropriate vehicle to test under this paragraph (g)(2)(ii), they may 
submit an engineering analysis that describes why an appropriate vehicle 
is not available or not appropriate, and includes data and information 
supporting specific credit values, using good engineering judgment.
    (iii) Subtract the CO2 emissions determined from testing 
under paragraph (g)(1)(i) of this section from the CO2 
emissions determined from testing under paragraph (g)(1)(ii) of this 
section and round to the nearest 0.1

[[Page 1117]]

grams/mile. If the result is less than or equal to zero, the air 
conditioning system is not eligible to generate credits. If the result 
is greater than or equal to the total of the gram per mile credits 
determined in paragraph (b) of this section, then the air conditioning 
system is eligible to generate the maximum allowable value determined in 
paragraph (b) of this section. If the result is greater than zero but 
less than the total of the gram per mile credits determined in paragraph 
(b) of this section, then the air conditioning system is eligible to 
generate credits in the amount determined by subtracting the 
CO2 emissions determined from testing under paragraph 
(g)(1)(i) of this section from the CO2 emissions determined 
from testing under paragraph (g)(1)(ii) of this section and rounding to 
the nearest 0.1 grams/mile.
    (3) For the first model year for which an air conditioning system is 
expected to generate credits, the manufacturer must select for testing 
the projected highest-selling configuration within each combination of 
vehicle platform and air conditioning system (as those terms are defined 
in Sec.86.1803). The manufacturer must test at least one unique air 
conditioning system within each vehicle platform in a model year, unless 
all unique air conditioning systems within a vehicle platform have been 
previously tested. A unique air conditioning system design is a system 
with unique or substantially different component designs or types and/or 
system control strategies (e.g., fixed-displacement vs. variable 
displacement compressors, orifice tube vs. thermostatic expansion valve, 
single vs. dual evaporator, etc.). In the first year of such testing, 
the tested vehicle configuration shall be the highest production vehicle 
configuration within each platform. In subsequent model years the 
manufacturer must test other unique air conditioning systems within the 
vehicle platform, proceeding from the highest production untested system 
until all unique air conditioning systems within the platform have been 
tested, or until the vehicle platform experiences a major redesign. 
Whenever a new unique air conditioning system is tested, the highest 
production configuration using that system shall be the vehicle selected 
for testing. Credits may continue to be generated by the air 
conditioning system installed in a vehicle platform provided that:
    (i) The air conditioning system components and/or control strategies 
do not change in any way that could be expected to cause a change in its 
efficiency;
    (ii) The vehicle platform does not change in design such that the 
changes could be expected to cause a change in the efficiency of the air 
conditioning system; and
    (iii) The manufacturer continues to test at least one unique air 
conditioning system within each platform using the air conditioning 
system, in each model year, until all unique air conditioning systems 
within each platform have been tested.
    (4) Each air conditioning system must be tested and must meet the 
testing criteria in order to be allowed to generate credits. Credits may 
continue to be generated by an air conditioning system in subsequent 
model years if the manufacturer continues to test at least one unique 
air conditioning system within each platform on an annual basis, unless 
all systems have been previously tested, as long as the air conditioning 
system and vehicle platform do not change substantially.
    (h) The following definitions apply to this section:
    (1) Reduced reheat, with externally-controlled, variable 
displacement compressor means a system in which compressor displacement 
is controlled via an electronic signal, based on input from sensors 
(e.g., position or setpoint of interior temperature control, interior 
temperature, evaporator outlet air temperature, or refrigerant 
temperature) and air temperature at the outlet of the evaporator can be 
controlled to a level at 41 [deg]F, or higher.
    (2) Reduced reheat, with externally-controlled, fixed-displacement 
or pneumatic variable displacement compressor means a system in which 
the output of either compressor is controlled by cycling the compressor 
clutch off-and-on via an electronic signal, based on input from sensors 
(e.g., position or setpoint of interior temperature control, interior 
temperature, evaporator outlet air

[[Page 1118]]

temperature, or refrigerant temperature) and air temperature at the 
outlet of the evaporator can be controlled to a level at 41 [deg]F, or 
higher.
    (3) Default to recirculated air mode means that the default position 
of the mechanism which controls the source of air supplied to the air 
conditioning system shall change from outside air to recirculated air 
when the operator or the automatic climate control system has engaged 
the air conditioning system (i.e., evaporator is removing heat), except 
under those conditions where dehumidification is required for visibility 
(i.e., defogger mode). In vehicles equipped with interior air quality 
sensors (e.g., humidity sensor, or carbon dioxide sensor), the controls 
may determine proper blend of air supply sources to maintain freshness 
of the cabin air and prevent fogging of windows while continuing to 
maximize the use of recirculated air. At any time, the vehicle operator 
may manually select the non-recirculated air setting during vehicle 
operation but the system must default to recirculated air mode on 
subsequent vehicle operations (i.e., next vehicle start). The climate 
control system may delay switching to recirculation mode until the 
interior air temperature is less than the outside air temperature, at 
which time the system must switch to recirculated air mode.
    (4) Blower motor controls which limit waste energy means a method of 
controlling fan and blower speeds which does not use resistive elements 
to decrease the voltage supplied to the motor.
    (5) Improved condensers and/or evaporators means that the 
coefficient of performance (COP) of air conditioning system using 
improved evaporator and condenser designs is 10 percent higher, as 
determined using the bench test procedures described in SAE J2765 
``Procedure for Measuring System COP of a Mobile Air Conditioning System 
on a Test Bench,'' when compared to a system using standard, or prior 
model year, component designs (SAE J2765 is incorporated by reference in 
Sec.86.1). The manufacturer must submit an engineering analysis 
demonstrating the increased improvement of the system relative to the 
baseline design, where the baseline component(s) for comparison is the 
version which a manufacturer most recently had in production on the same 
vehicle design or in a similar or related vehicle model. The dimensional 
characteristics (e.g., tube configuration/thickness/spacing, and fin 
density) of the baseline component(s) shall be compared to the new 
component(s) to demonstrate the improvement in coefficient of 
performance.
    (6) Oil separator means a mechanism which removes at least 50 
percent of the oil entrained in the oil/refrigerant mixture exiting the 
compressor and returns it to the compressor housing or compressor inlet, 
or a compressor design which does not rely on the circulation of an oil/

    (7) Advanced technology air conditioning compressor means an air 
conditioning compressor with improved efficiency relative to fixed-
displacement compressors. Efficiency gains are derived from improved 
internal valve systems that optimize the internal refrigerant flow 
across the range of compressor operator conditions through the addition 
of a variable crankcase suction valve.

Sec.86.1869-12  CO2 credits for off-cycle CO2 reducing technologies.

    This section describes how manufacturers may generate credits for 
off-cycle CO2-reducing technologies. The provisions of this 
section do not apply for non-MDPV heavy-duty vehicles, except that Sec.
86.1819-14(d)(13) describes how to apply paragraphs (c) and (d) of this 
section for those vehicles.
    (a) Manufacturers may generate credits for CO2-reducing 
technologies where the CO2 reduction benefit of the 
technology is not adequately captured on the Federal Test Procedure and/
or the Highway Fuel Economy Test such that the technology would not be 
otherwise installed for purposes of reducing emissions (directly or 
indirectly) over those test cycles for compliance with the GHG 
standards. These technologies

[[Page 1119]]

must have a measurable, demonstrable, and verifiable real-world 
CO2 reduction that occurs outside the conditions of the 
Federal Test Procedure and the Highway Fuel Economy Test. These optional 
credits are referred to as ``off-cycle'' credits. The technologies must 
not be integral or inherent to the basic vehicle design, such as engine, 
transmission, mass reduction, passive aerodynamic design, and tire 
technologies. Technologies installed for non-off-cycle emissions related 
reasons are also not eligible as they would be considered part of the 
baseline vehicle design. The technology must not be inherent to the 
design of occupant comfort and entertainment features except for 
technologies related to reducing passenger air conditioning demand and 
improving air conditioning system efficiency. Notwithstanding the 
provisions of this paragraph (a), off-cycle menu technologies included 
in paragraph (b) of this section remain eligible for credits. Off-cycle 
technologies used to generate emission credits are considered emission-
related components subject to applicable requirements and must be 
demonstrated to be effective for the full useful life of the vehicle. 
Unless the manufacturer demonstrates that the technology is not subject 
to in-use deterioration, the manufacturer must account for the 
deterioration in their analysis. Durability evaluations of off-cycle 
technologies may occur at any time throughout a model year, provided 
that the results can be factored into the data provided in the model 
year report. Off-cycle credits may not be approved for crash-avoidance 
technologies, safety critical systems or systems affecting safety-
critical functions, or technologies designed for the purpose of reducing 
the frequency of vehicle crashes. Off-cycle credits may not be earned 
for technologies installed on a motor vehicle to attain compliance with 
any vehicle safety standard or any regulation set forth in Title 49 of 
the Code of Federal Regulations. The manufacturer must use one of the 
three options specified in this section to determine the CO2 
gram per mile credit applicable to an off-cycle technology. Note that 
the option provided in paragraph (b) of this section applies only to the 
2014 and later model years. The manufacturer should notify EPA in their 
pre-model year report of their intention to generate any credits under 
this section.
    (b) Credit available for certain off-cycle technologies. The 
provisions of this paragraph (b) are applicable only to 2014 and later 
model year vehicles. EPA may request data, engineering analyses, or 
other information that supports a manufacturer's use of the credits in 
this paragraph (b).
    (1) The manufacturer may generate a CO2 gram/mile credit 
for certain technologies as specified in this paragraph (b)(1). 
Technology definitions are in paragraph (b)(4) of this section. 
Calculated credit values shall be rounded to the nearest 0.1 grams/mile.
    (i) Waste heat recovery. The credit shall be calculated using the 
following formula, rounded to the nearest 0.1 grams/mile:
[GRAPHIC] [TIFF OMITTED] TR15OC12.044

Where:

ELR = the electrical load reduction of the waste heat recovery system, 
          in Watts, calculated as an average over 5-cycle testing.

    (ii) High efficiency exterior lights. Credits may be accrued for 
high efficiency lighting as defined in paragraph (b)(4) of this section 
based on the lighting locations with such lighting installed. Credits 
for high efficiency lighting are the sum of the credits for the 
applicable lighting locations in the following table (rounded to the 
nearest 0.1 grams/mile), or, if all lighting locations in the table are 
equipped with high efficiency lighting, the total credit for high 
efficiency lighting shall be 1.0 grams/mile. Lighting components that 
result in credit levels less than those shown in the following table are 
not eligible for credits.

          100.

    (2) The maximum allowable decrease in the manufacturer's combined 
passenger automobile and light truck fleet average CO2 
emissions attributable to use of the default credit values in paragraph 
(b)(1) of this section is 10 grams per mile. If the total of the 
CO2 g/mi credit values from paragraph (b)(1) of this section 
does not exceed 10 g/mi for any passenger automobile or light truck in a 
manufacturer's fleet, then the total off-cycle credits may be calculated 
according to paragraph (f) of this section. If the total of the 
CO2 g/mi credit values from paragraph (b)(1) of this section 
exceeds 10 g/mi for any passenger automobile or light truck in a 
manufacturer's fleet, then the gram per mile decrease for the combined 
passenger automobile and light truck fleet must be determined according 
to paragraph (b)(2)(i) of this section to determine whether the 10 g/mi 
limitation has been exceeded.
    (i) Determine the gram per mile decrease for the combined passenger 
automobile and light truck fleet using the following formula:
[GRAPHIC] [TIFF OMITTED] TR15OC12.050

Where:

Credits = The total of passenger automobile and light truck credits, in 
          Megagrams, determined according to paragraph (f) of this 
          section and limited to those credits accrued by using the 
          default gram per mile values in paragraph (b)(1) of this 
          section.
ProdC = The number of passenger automobiles produced by the 
          manufacturer and delivered for sale in the U.S.
ProdT = The number of light trucks produced by the 
          manufacturer and delivered for sale in the U.S.

    (ii) If the value determined in paragraph (b)(2)(i) of this section 
is greater than 10 grams per mile, the total credits, in Megagrams, that 
may be accrued by a manufacturer using the default gram per mile values 
in paragraph (b)(1) of this section shall be determined using the 
following formula:
[GRAPHIC] [TIFF OMITTED] TR15OC12.051


[[Page 1123]]


Where:

ProdC = The number of passenger automobiles produced by the 
          manufacturer and delivered for sale in the U.S.
ProdT = The number of light trucks produced by the 
          manufacturer and delivered for sale in the U.S.

    (iii) If the value determined in paragraph (b)(2)(i) of this section 
is not greater than 10 grams per mile, then the credits that may be 
accrued by a manufacturer using the default gram per mile values in 
paragraph (b)(1) of this section do not exceed the allowable limit, and 
total credits may be determined for each category of vehicles according 
to paragraph (f) of this section.
    (iv) If the value determined in paragraph (b)(2)(i) of this section 
is greater than 10 grams per mile, then the combined passenger 
automobile and light truck credits, in Megagrams, that may be accrued 
using the calculations in paragraph (f) of this section must not exceed 
the value determined in paragraph (b)(2)(ii) of this section. This 
limitation should generally be done by reducing the amount of credits 
attributable to the vehicle category that caused the limit to be 
exceeded such that the total value does not exceed the value determined 
in paragraph (b)(2)(ii) of this section.
    (3) In lieu of using the default gram per mile values specified in 
paragraph (b)(1) of this section for specific technologies, a 
manufacturer may determine an alternative value for any of the specified 
technologies. An alternative value must be determined using one of the 
methods specified in paragraph (c) or (d) of this section.
    (4) Definitions for the purposes of this paragraph (b) are as 
follows:
    (i) Active aerodynamic improvements means technologies that are 
automatically activated under certain conditions to improve aerodynamic 
efficiency (e.g., lowering of the coefficient of drag, or Cd), while 
preserving other vehicle attributes or functions.
    (ii) High efficiency exterior lighting means a lighting technology 
that, when installed on the vehicle, is expected to reduce the total 
electrical demand of the exterior lighting system when compared to 
conventional lighting systems. To be eligible for this credit, the high 
efficiency lighting must be installed in one or more of the following 
lighting components: low beam, high beam, parking/position, front and 
rear turn signals, front and rear side markers, taillights, and/or 
license plate lighting.
    (iii) Engine idle start-stop means a technology which enables a 
vehicle to automatically turn off the engine when the vehicle comes to a 
rest and restarts the engine when the driver applies pressure to the 
accelerator or releases the brake. Off-cycle engine start-stop credits 
will only be allowed for a vehicle if the Administrator has made a 
determination under the testing and calculation provisions in 40 CFR 
Part 600 that engine start-stop is the predominant operating mode for 
that vehicle.
    (iv) Solar panels means the external installation of horizontally-
oriented solar panels, with direct and unimpeded solar exposure to an 
overhead sun, on an electric vehicle, a plug-in hybrid electric vehicle, 
a fuel cell vehicle, or a hybrid electric vehicle, such that the solar 
energy is used to provide energy to the electric drive system of the 
vehicle by charging the battery or directly providing power to the 
electric motor or to essential vehicle systems (e.g., cabin heating or 
cooling/ventilation). The rated power of the solar panels used to 
determine the credit value must be determined under the standard test 
conditions of 1,000 W/m\2\ direct solar irradiance at a panel 
temperature of 25 2 [deg]C with an air mass of 1.5 
spectrum (AM1.5).
    (v) Active transmission warmup means a system that uses waste heat 
from the vehicle to quickly warm the transmission fluid to an operating 
temperature range using a heat exchanger, increasing the overall 
transmission efficiency by reducing parasitic losses associated with the 
transmission fluid, such as losses related to friction and fluid 
viscosity.
    (vi) Active engine warmup means a system that uses waste heat from 
the vehicle to warm up targeted parts of the engine so that it reduces 
engine friction losses and enables the closed-loop fuel control more 
quickly. It allows a faster transition from cold operation to warm 
operation, decreasing

[[Page 1124]]

CO2 emissions, and increasing fuel economy.
    (vii) Waste heat recovery means a system that captures heat that 
would otherwise be lost through the engine, exhaust system, or the 
radiator or other sources and converting that heat to electrical energy 
that is used to meet the electrical requirements of the vehicle or used 
to augment the warming of other load reduction technologies (e.g., cabin 
warming, active engine or transmission warm-up technologies). The amount 
of energy recovered is the average value over 5-cycle testing.
    (viii) Active seat ventilation means a device which draws air, 
pushes or forces air, or otherwise transfers heat from the seating 
surface which is in contact with the seat occupant and exhausts it to a 
location away from the seat. At a minimum, the driver and front 
passenger seat must utilize this technology for a vehicle to be eligible 
for credit.
    (ix) Solar reflective surface coating means a vehicle paint or other 
surface coating which reflects at least 65 percent of the impinging 
infrared solar energy, as determined using ASTM standards E903, E1918-
06, or C1549-09 (incorporated by reference in Sec.86.1). The coating 
must be applied at a minimum to all of the approximately horizontal 
surfaces of the vehicle that border the passenger and luggage 
compartments of the vehicle, (e.g., the rear deck lid and the cabin 
roof).
    (x) Passive cabin ventilation means ducts, devices, or methods which 
utilize convective airflow to move heated air from the cabin interior to 
the exterior of the vehicle.
    (xi) Active cabin ventilation means devices which mechanically move 
heated air from the cabin interior to the exterior of the vehicle.
    (xii) Electric heater circulation system means a system installed in 
a vehicle equipped with an engine idle start-stop system that continues 
to circulate heated air to the cabin when the engine is stopped during a 
stop-start event. This system must be calibrated to keep the engine off 
for a minimum of one minute when the external ambient temperature is 30 
[deg]F and when cabin heating is enabled.
    (xiii) High efficiency alternator means an alternator where the 
ratio of the alternator output power to the power supplied to the 
alternator is greater than 67 percent, as measured using the Verband der 
Automobilindustrie (VDA) efficiency measurement methodology.
    (c) Technology demonstration using EPA 5-cycle methodology. To 
demonstrate an off-cycle technology and to determine a CO2 
credit using the EPA 5-cycle methodology, the manufacturer shall 
determine the off-cycle city/highway combined carbon-related exhaust 
emissions benefit by using the EPA 5-cycle methodology described in 40 
CFR Part 600. This method may not be used for technologies that include 
elements (e.g., driver-selectable systems) that require additional 
analyses, data collection, projections, or modeling, or other 
assessments to determine a national average benefit of the technology. 
Testing shall be performed on a representative vehicle, selected using 
good engineering judgment, for each model type for which the credit is 
being demonstrated. The emission benefit of a technology is determined 
by testing both with and without the off-cycle technology operating. If 
a specific technology is not expected to change emissions on one of the 
five test procedures, the manufacturer may submit an engineering 
analysis to the EPA that demonstrates that the technology has no effect. 
If EPA concurs with the analysis, then multiple tests are not required 
using that test procedure; instead, only one of that test procedure 
shall be required--either with or without the technology installed and 
operating--and that single value will be used for all of the 5-cycle 
weighting calculations. Multiple off-cycle technologies may be 
demonstrated on a test vehicle. The manufacturer shall conduct the 
following steps and submit all test data to the EPA.
    (1) Testing without the off-cycle technology installed and/or 
operating.
    (i) Determine carbon-related exhaust emissions over the FTP, the 
HFET, the US06, the SC03, and the cold temperature FTP test procedures 
according to the test procedure provisions specified in 40 CFR part 600 
subpart B and using the calculation procedures specified in 40 CFR 
600.113-12. Run each of these

[[Page 1125]]

tests a minimum of three times without the off-cycle technology 
installed and operating and average the per phase (bag) results for each 
test procedure.
    (ii) Calculate the FTP and HFET carbon-related exhaust emissions 
from the FTP and HFET averaged per phase results.
    (iii) Calculate the combined city/highway carbon-related exhaust 
emission value from the FTP and HFET values determined in paragraph 
(c)(1)(ii) of this section, where the FTP value is weighted 55% and the 
HFET value is weighted 45%. The resulting value is the 2-cycle 
unadjusted combined city/highway carbon-related exhaust emissions value 
for the vehicle without the off-cycle technology.
    (iv) Calculate the 5-cycle weighted city/highway combined carbon-
related exhaust emissions from the averaged per phase results, where the 
5-cycle city value is weighted 55% and the 5-cycle highway value is 
weighted 45%. The resulting value is the 5-cycle adjusted combined city/
highway carbon-related exhaust emission value for the vehicle without 
the off-cycle technology.
    (2) Testing with the off-cycle technology installed and/or 
operating.
    (i) Determine carbon-related exhaust emissions over the FTP, the 
HFET, the US06, the SC03, and the cold temperature FTP test procedures 
according to the test procedure provisions specified in 40 CFR part 600 
subpart B and using the calculation procedures specified in 40 CFR 
600.113-12. Run each of these tests a minimum of three times with the 
off-cycle technology installed and operating and average the per phase 
(bag) results for each test procedure.
    (ii) Calculate the FTP and HFET carbon-related exhaust emissions 
from the FTP and HFET averaged per phase results.
    (iii) Calculate the combined city/highway carbon-related exhaust 
emission value from the FTP and HFET values determined in paragraph 
(c)(2)(ii) of this section, where the FTP value is weighted 55% and the 
HFET value is weighted 45%. The resulting value is the 2-cycle 
unadjusted combined city/highway carbon-related exhaust emissions value 
for the vehicle with the off-cycle technology.
    (iv) Calculate the 5-cycle weighted city/highway combined carbon-
related exhaust emissions from the averaged per phase results, where the 
5-cycle city value is weighted 55% and the 5-cycle highway value is 
weighted 45%. The resulting value is the 5-cycle adjusted combined city/
highway carbon-related exhaust emission value for the vehicle with the 
off-cycle technology.
    (3) Calculate the off-cycle credit in grams per mile using the 
following formula, rounding the result to the nearest 0.1 grams/mile:

Credit = (A-B)-(C-D)

Where:

Credit = the off-cycle benefit of the technology or technologies being 
          evaluated, subject to EPA approval;
A = the 5-cycle adjusted combined city/highway carbon-related exhaust 
          emission value for the vehicle without the off-cycle 
          technology, as calculated in paragraph (c)(1)(iv) of this 
          section;
B = 5-cycle adjusted combined city/highway carbon-related exhaust 
          emission value for the vehicle with the off-cycle technology, 
          as calculated in paragraph (c)(2)(iv) of this section;
C = 2-cycle unadjusted combined city/highway carbon-related exhaust 
          emissions value for the vehicle without the off-cycle 
          technology, as calculated in paragraph (c)(1)(iii) of this 
          section; and
D = 2-cycle unadjusted combined city/highway carbon-related exhaust 
          emissions value for the vehicle with the off-cycle technology, 
          as calculated in paragraph (c)(2)(iii) of this section.
    (4) Submit all test values to EPA, and include an engineering 
analysis describing the technology and how it provides off-cycle 
emission benefits. EPA may request additional testing if we determine 
that additional testing would be likely to provide significantly greater 
confidence in the estimates of off-cycle technology benefits.
    (d) Technology demonstration using alternative EPA-approved 
methodology. (1) This option may be used only with EPA approval, and the 
manufacturer must be able to justify to the Administrator why the 5-
cycle option described in paragraph (c) of this section insufficiently 
characterizes the effectiveness of the off-cycle technology. In cases 
where the EPA 5-cycle methodology described in paragraph (c) of this 
section

[[Page 1126]]

cannot adequately measure the emission reduction attributable to an off-
cycle technology, the manufacturer may develop an alternative approach. 
Prior to a model year in which a manufacturer intends to seek these 
credits, the manufacturer must submit a detailed analytical plan to EPA. 
The manufacturer may seek EPA input on the proposed methodology prior to 
conducting testing or analytical work, and EPA will provide input on the 
manufacturer's analytical plan. The alternative demonstration program 
must be approved in advance by the Administrator and should:
    (i) Use modeling, on-road testing, on-road data collection, or other 
approved analytical or engineering methods;
    (ii) Be robust, verifiable, and capable of demonstrating the real-
world emissions benefit with strong statistical significance;
    (iii) Result in a demonstration of baseline and controlled emissions 
over a wide range of driving conditions and number of vehicles such that 
issues of data uncertainty are minimized;
    (iv) Result in data on a model type basis unless the manufacturer 
demonstrates that another basis is appropriate and adequate.
    (2) Notice and opportunity for public comment. (i) The Administrator 
will publish a notice of availability in the Federal Register notifying 
the public of a manufacturer's proposed alternative off-cycle credit 
calculation methodology. The notice will include details regarding the 
proposed methodology but will not include any Confidential Business 
Information. The notice will include instructions on how to comment on 
the methodology. The Administrator will take public comments into 
consideration in the final determination and will notify the public of 
the final determination. Credits may not be accrued using an approved 
methodology until the first model year for which the Administrator has 
issued a final approval.
    (ii) The Administrator may waive these notice and comment 
requirements for technologies for which EPA has previously approved a 
methodology for determining credits. To qualify for this waiver, the new 
application must be substantially identical in form, content, and 
methodology to the application for a previously approved methodology, 
and must include the following:
    (A) A cite to the appropriate previously approved methodology, 
including the appropriate Federal Register Notice and any subsequent EPA 
documentation of the Administrator's decision;
    (B) All necessary manufacturer- and vehicle-specific test data, 
modeling, and credit calculations; and,
    (C) Any other vehicle- or technology-specific details required 
pursuant to the previously approved methodology to assess and support an 
appropriate credit value.
    (iii) A waiver of the notice and comment requirements does not imply 
a determination that a specific credit value for a given technology is 
appropriate, and nor does it imply a waiver from the requirements in 
paragraphs (d)(1) and (e) of this section.
    (iv) The Administrator retains the option to require a notice and 
opportunity for public comment in cases where a new application deviates 
in significant respects from a previously approved methodology or raises 
novel substantive issues.
    (3) With respect to fuel consumption improvement values applicable 
to the determination of average fuel economy under 600.510-12(c)(3) for 
the 2017 and later model years, EPA will consult with the U.S.

the application available to the public for comment, as described in 
paragraph (d)(2) of this section, within 60 days of receiving a complete 
application. The public review period will be specified as 30 days, 
during which time the public may submit comments. Manufacturers may 
submit a written rebuttal of comments for EPA consideration or may 
revise their application in response to comments. A revised application 
should be submitted after the end of the public review period, and EPA 
will review the application as if it was a new application submitted 
under this paragraph (e)(3).
    (4) EPA decision. (i) For credits under paragraph (c) of this 
section, EPA will notify the manufacturer of its decision within 60 days 
of receiving a complete application.

public.
    (f) Calculation of total off-cycle credits. Total off-cycle credits 
in Megagrams of CO2 (rounded to the nearest whole number) 
shall be calculated separately for passenger automobiles and light 
trucks according to the following formula:

Total Credits (Megagrams) = (Credit x Production x VLM) / 1,000,000

Where:

Credit = the credit value in grams per mile determined in paragraph (b), 
          (c) or (d) of this section.
Production = The total number of passenger automobiles or light trucks, 
          whichever is applicable, produced with the off-cycle 
          technology to which to the credit value determined in 
          paragraph (b), (c), or (d) of this section applies.
VLM = vehicle lifetime miles, which for passenger automobiles shall be 
          195,264 and for light trucks shall be 225,865.

Sec.86.1870-12  CO2 credits for qualifying full-size light pickup 
trucks.

    Full-size pickup trucks may be eligible for additional credits based 
on the implementation of hybrid technologies or on exhaust emission 
performance, as described in this section. Credits may be generated 
under either paragraph (a) or (b) of this section for a qualifying 
pickup truck, but not both. The provisions of this section do not apply 
for heavy-duty vehicles.
    (a) Credits for implementation of hybrid electric technology. Full 
size pickup trucks that implement hybrid electric technologies may be 
eligible for an additional credit under this paragraph (a). Pickup 
trucks earning the credits under this paragraph (a) may not earn the 
credits described in paragraph (b) of this section. To claim this 
credit, the manufacturer must measure the recovered energy over the 
Federal Test Procedure according to 40 CFR 600.116-12(d) to determine 
whether a vehicle is a mild or strong hybrid electric vehicle. To 
provide for EPA testing, the vehicle must be able to broadcast battery 
pack voltage via an on-board diagnostics parameter ID channel.
    (1) Full size pickup trucks that are mild hybrid electric vehicles 
and that are produced in the 2017 through 2021 model years are eligible 
for a credit of 10 grams/mile. To receive this credit in a model year, 
the manufacturer must produce a quantity of mild hybrid electric full 
size pickup trucks such that the proportion of production of such 
vehicles, when compared to the manufacturer's total production of full 
size pickup trucks, is not less than the amount specified in the table 
below for that model year.

    (2) Full size pickup trucks that are strong hybrid electric vehicles 
and that are produced in the 2017 through 2021 model years are eligible 
for a credit of 20 grams/mile. To receive this credit in a model year, 
the manufacturer must produce a quantity of strong hybrid electric full 
size pickup trucks such that the proportion of production of such 
vehicles, when compared to the manufacturer's total production of full 
size pickup trucks, is not less than 10 percent in that model year.
    (3) If you produce both mild and strong hybrid electric full size 
pickup trucks but do not qualify for credits under paragraph (a)(1) or 
(2) of this section, your hybrid electric full size pickup trucks may be 
eligible for a credit of 10 grams/mile. To receive this credit in a 
given model year, you must produce a quantity of hybrid electric full 
size pickup trucks such that the proportion of combined mild and strong 
full size hybrid electric pickup trucks produced in a model year, when 
compared to your total production of full size pickup trucks, is not 
less than the required minimum percentages specified in paragraph (a)(1) 
of this section.
    (b) Credits for emission reduction performance. Full size pickup 
trucks that achieve carbon-related exhaust emission values below the 
applicable target value determined in Sec.86.1818-12(c)(3) may be 
eligible for an additional credit. For the purposes of this paragraph 
(b), carbon-related exhaust emission values may include any applicable 
air conditioning leakage and/or efficiency credits as determined in 
Sec.86.1867 and Sec.86.1868. Pickup trucks earning the credits under 
this paragraph (b) may not earn credits described in paragraph (a) of 
this section and may not earn credits based on the production 
multipliers described in Sec.86.1866-12(b).
    (1) Full size pickup trucks that are produced in the 2017 through 
2021 model years and that achieve carbon-related exhaust emissions less

    (2) Full size pickup trucks that are produced in the 2017 through 
2021 model years and that achieve carbon-related exhaust emissions less 
than or equal to the applicable target value determined in Sec.
86.1818-12(c)(3) multiplied by 0.80 (rounded to the nearest gram/mile) 
in a model year are eligible for a credit of 20 grams/mile. A pickup 
truck that qualifies for this credit in a model year may claim this 
credit for a maximum of four subsequent model years (a total of five 
consecutive model years) if the carbon-related exhaust emissions of that 
pickup truck do not increase relative to the emissions in the model year 
in which the pickup truck first qualified for the credit. This credit 
may not be claimed in any model year after 2021. To qualify for this 
credit in a model year, the manufacturer must produce a quantity of full 
size pickup trucks that meet the emission requirements of this paragraph 
(b)(2) such that the proportion of production of such vehicles, when 
compared to the manufacturer's total production of full size pickup 
trucks, is not less than 10 percent in that model year.
    (c) Calculation of total full size pickup truck credits. Total

ProductionT15) + (20 x ProductionSHEV) + (20 x 
ProductionT20)] x 225,865) / 1,000,000

Where:

ProductionMHEV = The total number of mild hybrid electric 
          full size pickup trucks produced with a credit value of 10 
          grams per mile from paragraph (a)(1) of this section.
ProductionT15 = The total number of full size pickup trucks 
          produced with a performance-based credit value of 10 grams per 
          mile from paragraph (b)(1) of this section.
ProductionSHEV = The total number of strong hybrid electric 
          full size pickup trucks produced with a credit value of 20 
          grams per mile from paragraph (a)(2) of this section.
ProductionT20 = The total number of full size pickup trucks 
          produced with a performance-based credit value of 20 grams per 
          mile from paragraph (b)(2) of this section.

Sec.86.1871-12  Optional early CO2 credit programs.

    Manufacturers may optionally generate CO2 credits in the 
2009 through 2011 model years for use in the 2012 and later model years 
subject to EPA approval and to the provisions of this section. The 
provisions of Sec.86.1819-14(k)(1) and (2) apply instead of the 
provisions of this section for non-MDPV heavy-duty vehicles. 
Manufacturers may generate early fleet average credits, air conditioning 
leakage credits, air conditioning efficiency credits, early advanced 
technology credits, and early off-cycle technology credits. 
Manufacturers generating any credits under this section must submit an 
early credits report to the Administrator as required in this section. 
The terms ``sales'' and ``sold'' as used in this section shall mean 
vehicles produced for U.S. sale, where ``U.S.'' means the states and 
territories of the United States. The expiration date of unused 
CO2 credits is based on the model year

[[Page 1130]]

in which the credits are earned, as described in Sec.86.1865-12(k)(6).
    (a) Early fleet average CO2 reduction credits. 
Manufacturers may optionally generate credits for reductions in their 
fleet average CO2 emissions achieved in the 2009 through 2011 
model years. To generate early fleet average CO2 reduction 
credits, manufacturers must select one of the four pathways described in 
paragraphs (a)(1) through (4) of this section. The manufacturer may 
select only one pathway, and that pathway must remain in effect for the 
2009 through 2011 model years. Fleet average credits (or debits) must be 
calculated and reported to EPA for each model year under each selected 
pathway.
    (1) Pathway 1. To earn credits under this pathway, the manufacturer 
shall calculate an average carbon-related exhaust emission value to the 
nearest one gram per mile for the classes of motor vehicles identified 
in this paragraph (a)(1), and the results of such calculations will be 
reported to the Administrator for use in determining compliance with the 
applicable CO2 early credit threshold values.
    (i) An average carbon-related exhaust emission value calculation 
will be made for the combined LDV/LDT1 averaging set, where the terms 
LDV and LDT1 are as defined in Sec.86.1803.
    (ii) An average carbon-related exhaust emission value calculation 
will be made for the combined LDT2/HLDT/MDPV averaging set, where the 
terms LDT2, HLDT, and MDPV are as defined in Sec.86.1803.
    (iii) Average carbon-related exhaust emission values shall be 
determined according to the provisions of Sec.600.510-12 of this 
chapter, except that:
    (A) [Reserved]
    (B) The average carbon-related exhaust emissions for alcohol fueled 
model types shall be calculated according to the provisions of Sec.
600.510-12(j)(2)(ii)(B) of this chapter, without the use of the 0.15 
multiplicative factor.
    (C) The average carbon-related exhaust emissions for natural gas 
fueled model types shall be calculated according to the provisions of 
Sec.600.510-12(j)(2)(iii)(B) of this chapter, without the use of the 
0.15 multiplicative factor.
    (D) The average carbon-related exhaust emissions for alcohol dual 
fueled model types shall be the value measured using gasoline or diesel 
fuel, as applicable, and shall be calculated according to the provisions 
of Sec.600.510-12(j)(2)(vi) of this chapter, without the use of the 
0.15 multiplicative factor and with F = 0. For the 2010 and 2011 model 
years only, if the California Air Resources Board has approved a 
manufacturer's request to use a non-zero value of F, the manufacturer 
may use such an approved value.
    (E) The average carbon-related exhaust emissions for natural gas 
dual fueled model types shall be the value measured using gasoline or 
diesel fuel, as applicable, and shall be calculated according to the 
provisions of Sec.600.510-12(j)(2)(vii) of this chapter, without the 
use of the 0.15 multiplicative factor and with F = 0. For the 2010 and 
2011 model years only, if the California Air Resources Board has 
approved a manufacturer's request to use a non-zero value of F, the 
manufacturer may use such an approved value.
    (F) Carbon-related exhaust emission values for electric, fuel cell, 
and plug-in hybrid electric model types shall be included in the fleet 
average determined under paragraph (a)(1) of this section only to the 
extent that such vehicles are not being used to generate early advanced 
technology vehicle credits under paragraph (c) of this section.
    (iv) Fleet average CO2 credit threshold values.

------------------------------------------------------------------------

    (v) Credits are earned on the last day of the model year. 
Manufacturers must calculate, for a given model year, the number of 
credits or debits it has generated according to the following equation, 
rounded to the nearest megagram:

CO2 Credits or Debits (Mg) = [(CO2 Credit 
Threshold - Manufacturer's Sales Weighted Fleet Average CO2

[[Page 1131]]

Emissions) x (Total Number of Vehicles Sold) x (Vehicle Lifetime Miles)] 
/ 1,000,000

Where:

CO2 Credit Threshold = the applicable credit threshold value 
          for the model year and vehicle averaging set as determined by 
          paragraph (a)(1)(iv) of this section;
Manufacturer's Sales Weighted Fleet Average CO2 Emissions = 
          average calculated according to paragraph (a)(1)(iii) of this 
          section;
Total Number of Vehicles Sold = The number of vehicles domestically sold 
          as defined in Sec.600.511-80 of this chapter; and
Vehicle Lifetime Miles is 195,264 for the LDV/LDT1 averaging set and 
          225,865 for the LDT2/HLDT/MDPV averaging set.

    (vi) Deficits generated against the applicable CO2 credit 
threshold values in paragraph (a)(1)(iv) of this section in any 
averaging set for any of the 2009-2011 model years must be offset using 
credits accumulated by any averaging set in any of the 2009-2011 model 
years before determining the number of credits that may be carried 
forward to the 2012. Deficit carry forward and credit banking provisions 
of Sec.86.1865-12 apply to early credits earned under this paragraph 
(a)(1), except that deficits may not be carried forward from any of the 
2009-2011 model years into the 2012 model year, and credits earned in 
the 2009 model year may not be traded to other manufacturers.
    (2) Pathway 2. To earn credits under this pathway, manufacturers 
shall calculate an average carbon-related exhaust emission value to the 
nearest one gram per mile for the classes of motor vehicles identified 
in paragraph (a)(1) of this section, and the results of such 
calculations will be reported to the Administrator for use in 
determining compliance with the applicable CO2 early credit 
threshold values.
    (i) Credits under this pathway shall be calculated according to the 
provisions of paragraph (a)(1) of this section, except credits may only 
be generated by vehicles sold in a model year in California and in 
states with a section 177 program in effect in that model year. For the 
purposes of this section, ``section 177 program'' means State 
regulations or other laws that apply to vehicle emissions from any of 
the following categories of motor vehicles: Passenger automobiles, 
light-duty trucks up through 6,000 pounds GVWR, and medium-duty vehicles 
from 6,001 to 14,000 pounds GVWR, as these categories of motor vehicles 
are defined in the California Code of Regulations, Title 13, Division 3, 
Chapter 1, Article 1, Section 1900.
    (ii) A deficit in any averaging set for any of the 2009-2011 model 
years must be offset using credits accumulated by any averaging set in 
any of the 2009-2011 model years before determining the number of 
credits that may be carried forward to the 2012 model year. Deficit 
carry forward and credit banking provisions of Sec.86.1865-12 apply to 
early credits earned under this paragraph (a)(1), except that deficits 
may not be carried forward from any of the 2009-2011 model years into 
the 2012 model year, and credits earned in the 2009 model year may not 
be traded to other manufacturers.
    (3) Pathway 3. Pathway 3 credits are those credits earned under 
Pathway 2 as described in paragraph (a)(2) of this section in California 
and in the section 177 states determined in paragraph (a)(2)(i) of this 
section, combined with additional credits earned in the set of states 
that does not include California and the section 177 states determined 
in paragraph (a)(2)(i) of this section and calculated according to this 
paragraph (a)(3).
    (i) Manufacturers shall earn additional credits under Pathway 3 by 
calculating an average carbon-related exhaust emission value to the 
nearest one gram per mile for the classes of motor vehicles identified 
in this paragraph (a)(3). The results of such calculations will be 
reported to the Administrator for use in determining compliance with the 
applicable CO2 early credit threshold values.
    (ii) An average carbon-related exhaust emission value calculation 
will be made for the passenger automobile averaging set. The term 
``passenger automobile'' shall have the meaning given by the Department 
of Transportation at 49 CFR 523.4 for the specific model year for which 
the calculation is being made.
    (iii) An average carbon-related exhaust emission value calculation 
will be made for the light truck averaging set. The term ``light truck'' 
shall have

[[Page 1132]]

the meaning given by the Department of Transportation at 49 CFR 523.5 
for the specific model year for which the calculation is being made.
    (iv) Average carbon-related exhaust emission values shall be 
determined according to the provisions of Sec.600.510-12 of this 
chapter, except that:
    (A) Vehicles sold in California and the section 177 states 
determined in paragraph (a)(2)(i) of this section shall not be included.
    (B) The average carbon-related exhaust emissions for alcohol fueled 
model types shall be calculated according to the provisions of Sec.
600.510-12(j)(2)(ii)(B) of this chapter, without the use of the 0.15 
multiplicative factor.
    (C) The average carbon-related exhaust emissions for natural gas 
fueled model types shall be calculated according to the provisions of 
Sec.600.510-12(j)(2)(iii)(B) of this chapter, without the use of the 
0.15 multiplicative factor.
    (D) The average carbon-related exhaust emissions for alcohol dual 
fueled model types shall be calculated according to the provisions of 
Sec.600.510-12(j)(2)(vi) of this chapter, without the use of the 0.15 
multiplicative factor and with F = 0.
    (E) The average carbon-related exhaust emissions for natural gas 
dual fueled model types shall be calculated according to the provisions 
of Sec.600.510-12(j)(2)(vii) of this chapter, without the use of the 
0.15 multiplicative factor and with F = 0.
    (F) Electric, fuel cell, and plug-in hybrid electric model type 
carbon-related exhaust emission values shall be included in the fleet 
average determined under paragraph (a)(1) of this section only to the 
extent that such vehicles are not being used to generate early advanced 
technology vehicle credits under paragraph (c) of this section.
    (v) Pathway 3 fleet average CO2 credit threshold values.
    (A) For 2009 and 2010 model year passenger automobiles, the fleet 
average CO2 credit threshold value is 323 grams/mile.
    (B) For 2009 model year light trucks the fleet average 
CO2 credit threshold value is 381 grams/mile, or, if the 
manufacturer chose to optionally meet an alternative manufacturer-
specific light truck fuel economy standard calculated under 49 CFR 533.5 
for the 2009 model year, the gram per mile fleet average CO2 
credit threshold shall be the CO2 value determined by 
dividing 8887 by that alternative manufacturer-specific fuel economy 
standard and rounding to the nearest whole gram per mile.
    (C) For 2010 model year light trucks the fleet average 
CO2 credit threshold value is 376 grams/mile, or, if the 
manufacturer chose to optionally meet an alternative manufacturer-
specific light truck fuel economy standard calculated under 49 CFR 533.5 
for the 2010 model year, the gram per mile fleet average CO2 
credit threshold shall be the CO2 value determined by 
dividing 8887 by that alternative manufacturer-specific fuel economy 
standard and rounding to the nearest whole gram per mile.
    (D) For 2011 model year passenger automobiles the fleet average 
CO2 credit threshold value is the value determined by 
dividing 8887 by the manufacturer-specific passenger automobile fuel 
economy standard for the 2011 model year determined under 49 CFR 531.5 
and rounding to the nearest whole gram per mile.
    (E) For 2011 model year light trucks the fleet average 
CO2 credit threshold value is the value determined by 
dividing 8887 by the manufacturer-specific light truck fuel economy 
standard for the 2011 model year determined under 49 CFR 533.5 and 
rounding to the nearest whole gram per mile.
    (vi) Credits are earned on the last day of the model year. 
Manufacturers must calculate, for a given model year, the number of 
credits or debits it has generated according to the following equation, 
rounded to the nearest megagram:

CO2 Credits or Debits (Mg) = [(CO2 Credit 
Threshold - Manufacturer's Sales Weighted Fleet Average CO2 
Emissions) x (Total Number of Vehicles Sold) x (Vehicle Lifetime Miles)] 
/ 1,000,000

Where:

CO2 Credit Threshold = the applicable credit threshold value 
          for the model year and vehicle averaging set as determined by 
          paragraph (a)(3)(v) of this section.
Manufacturer's Sales Weighted Fleet Average CO2 Emissions = 
          average calculated

[[Page 1133]]

          according to paragraph (a)(3)(iv) of this section.
Total Number of Vehicles Sold = The number of vehicles domestically sold 
          as defined in Sec.600.511 of this chapter except that 
          vehicles sold in California and the section 177 states 
          determined in paragraph (a)(2)(i) of this section shall not be 
          included.
Vehicle Lifetime Miles is 195,264 for the LDV/LDT1 averaging set and 
          225,865 for the LDT2/HLDT/MDPV averaging set.

    (vii) Deficits in any averaging set for any of the 2009-2011 model 
years must be offset using credits accumulated by any averaging set in 
any of the 2009-2011 model years before determining the number of 
credits that may be carried forward to the 2012. Deficit carry forward 
and credit banking provisions of Sec.86.1865-12 apply to early credits 
earned under this paragraph (a)(3), except that deficits may not be 
carried forward from any of the 2009-2011 model years into the 2012 
model year, and credits earned in the 2009 model year may not be traded 
to other manufacturers.
    (4) Pathway 4. Pathway 4 credits are those credits earned under 
Pathway 3 as described in paragraph (a)(3) of this section in the set of 
states that does not include California and the section 177 states 
determined in paragraph (a)(2)(i) of this section and calculated 
according to paragraph (a)(3) of this section. Credits may only be 
generated by vehicles sold in the set of states that does not include 
California and the section 177 states determined in paragraph (a)(2)(i) 
of this section.
    (b) Early air conditioning leakage and efficiency credits. (1) 
Manufacturers may optionally generate air conditioning refrigerant 
leakage credits according to the provisions of Sec.86.1867 and/or air 
conditioning efficiency credits according to the provisions of Sec.
86.1868 in model years 2009 through 2011. Credits must be tracked by 
model type and model year.
    (2) Manufacturers must be participating in one of the early fleet 
average credit pathways described in paragraphs (a)(1), (2), or (3) of 
this section in order to generate early air conditioning credits for 
vehicles sold in California and the section 177 states as determined in 
paragraph (a)(2)(i) of this section. Manufacturers that select Pathway 4 
as described in paragraph (a)(4) of this section may not generate early 
air conditioning credits for vehicles sold in California and the section 
177 states as determined in paragraph (a)(2)(i) of this section. 
Manufacturers not participating in one of the early fleet average credit 
pathways described in this section may generate early air conditioning 
credits only for vehicles sold in states other than in California and 
the section 177 states as determined in paragraph (a)(2)(i) of this 
section.
    (c) Early advanced technology vehicle incentive. Vehicles eligible 
for this incentive are electric vehicles, fuel cell vehicles, and plug-
in hybrid electric vehicles, as those terms are defined in Sec.
86.1803-01. If a manufacturer chooses to not include electric vehicles, 
fuel cell vehicles, and plug-in hybrid electric vehicles in their fleet 
averages calculated under any of the early credit pathways described in 
paragraph (a) of this section, the manufacturer may generate early 
advanced technology vehicle credits pursuant to this paragraph (c).
    (1) The manufacturer shall record the sales and carbon-related 
exhaust emission values of eligible vehicles by model type and model 
year for model years 2009 through 2011 and report these values to the 
Administrator under paragraph (e) of this section.
    (2) Manufacturers may use the 2009 through 2011 eligible vehicles in 
their fleet average calculations starting with the 2012 model year, 
subject to a five-year carry-forward limitation.
    (i) Eligible 2009 model year vehicles may be used in the calculation 
of a manufacturer's fleet average carbon-related exhaust emissions in 
the 2012 through 2014 model years.
    (ii) Eligible 2010 model year vehicles may be used in the 
calculation of a manufacturer's fleet average carbon-related exhaust 
emissions in the 2012 through 2015 model years.
    (iii) Eligible 2011 model year vehicles may be used in the 
calculation of a manufacturer's fleet average carbon-related exhaust 
emissions in the 2012 through 2016 model years.
    (3)(i) To use the advanced technology vehicle incentive, the 
manufacturer will apply the 2009, 2010, and/or 2011

[[Page 1134]]

model type sales volumes and their model type emission levels to the 
manufacturer's fleet average calculation.
    (ii) The early advanced technology vehicle incentive must be used to 
offset a deficit in one of the 2012 through 2016 model years, as 
appropriate under paragraph (c)(2) of this section.
    (iii) The advanced technology vehicle sales and emission values may 
be included in a fleet average calculation for passenger automobiles or 
light trucks, but may not be used to generate credits in the model year 
in which they are included or in the averaging set in which they are 
used. Use of early advanced technology vehicle credits is limited to 
offsetting a deficit that would otherwise be generated without the use 
of those credits. Manufacturers shall report the use of such credits in 
their model year report for the model year in which the credits are 
used.
    (4) Manufacturers may use zero grams/mile to represent the carbon-
related exhaust emission values for the electric operation of 2009 
through 2011 model year electric vehicles, fuel cell vehicles, and plug-
in hybrid electric vehicles subject to the limitations in Sec.86.1866. 
The 2009 through 2011 model year vehicles using zero grams per mile 
shall count against the 200,000 or 300,000 caps on use of this credit 
value, whichever is applicable under Sec.86.1866.
    (d) Early off-cycle technology credits. Manufacturers may optionally 
generate credits for the implementation of certain CO2-
reducing technologies according to the provisions of Sec.86.1869 in 
model years 2009 through 2011. Credits must be tracked by model type and 
model year.
    (e) Early credit reporting requirements. Each manufacturer shall 
submit a report to the Administrator, known as the early credits report, 
that reports the credits earned in the 2009 through 2011 model years 
under this section.
    (1) The report shall contain all information necessary for the 
calculation of the manufacturer's early credits in each of the 2009 
through 2011 model years.
    (2) The early credits report shall be in writing, signed by the 
authorized representative of the manufacturer and shall be submitted no 
later than 90 days after the end of the 2011 model year.
    (3) Manufacturers using one of the optional early fleet average 
CO2 reduction credit pathways described in paragraph (a) of 
this section shall report the following information separately for the 
appropriate averaging sets (e.g. LDV/LDT1 and LDT2/HLDT/MDPV averaging 
sets for pathways 1 and 2; LDV, LDT/2011 MDPV, LDV/LDT1 and LDT2/HLDT/
MDPV averaging sets for Pathway 3; LDV and LDT/2011 MDPV averaging sets 
for Pathway 4):
    (i) The pathway that they have selected (1, 2, 3, or 4).
    (ii) A carbon-related exhaust emission value for each model type of 
the manufacturer's product line calculated according to paragraph (a) of 
this section.
    (iii) The manufacturer's average carbon-related exhaust emission 
value calculated according to paragraph (a) of this section for the 
applicable averaging set and region and all data required to complete 
this calculation.
    (iv) The credits earned for each averaging set, model year, and 
region, as applicable.
    (4) Manufacturers calculating early air conditioning leakage and/or 
efficiency credits under paragraph (b) of this section shall report the 
following information for each model year separately for passenger 
automobiles and light trucks and for each air conditioning system used 
to generate credits:
    (i) A description of the air conditioning system.
    (ii) The leakage and efficiency credit values and all the 
information required to determine these values.
    (iii) The total credits earned for each averaging set, model year, 
and region, as applicable.
    (5) Manufacturers calculating early advanced technology vehicle 
credits under paragraph (c) of this section shall report, for each model 
year and separately for passenger automobiles and light trucks, the 
following information:
    (i) The number of each model type of eligible vehicle produced.
    (ii) The carbon-related exhaust emission value by model type and 
model year.

[[Page 1135]]

    (6) Manufacturers calculating early off-cycle technology credits 
under paragraph (d) of this section shall report, for each model year 
and separately for passenger automobiles and light trucks, all test 
results and data required for calculating such credits.

Solicitation letters will be sent to potential participants in the order 
of their appearance on a randomized master owner list. The manufacturer 
or their representative shall perform the following steps:
    (a) The manufacturer or their representative shall mail solicitation 
letters in batches. The size of each batch is at least five times the 
required number of vehicles to be tested for the group that year. First 
class mail shall be used.
    (b) If the response rate is less than 20% after two to four weeks, 
the manufacturer or their representative shall make one more attempt and 
send a new solicitation package to the potential participants who have 
not yet responded.
    (c) A telephone questionnaire will be conducted on a random 
selection of returned, positive-response postcards.

Subpart T_Manufacturer-Run In-Use Testing Program for Heavy-Duty Diesel 
                                 Engines

    Source: 70 FR 34619, June 14, 2005, unless otherwise noted.



Sec.86.1901  What testing requirements apply to my engines that have
gone into service?

    (a) If you manufacture diesel heavy-duty engines above 8,500 lbs. 
GVWR

[[Page 1136]]

that are subject to engine-based exhaust emission standards under this 
part, you must test them as described in this subpart. You must measure 
all emissions listed in Sec.86.1910(d) other than PM beginning in 
calendar year 2005 and you must measure PM emissions beginning in 
calendar year 2007. See Sec.86.1930 for special provisions that may 
apply to manufacturers in the early years of this program.
    (b) We may void your certificate of conformity for an engine family 
if you do not meet your obligations under this subpart. We may also void 
individual tests and require you to retest those vehicles or take other 
appropriate measures in instances where you have not performed the 
testing in accordance with the requirements described in this subpart.
    (c) In this subpart, the term ``you'' refers to the certificate-
holder for any engines subject to the requirements of this subpart.
    (d) In this subpart, round means to round numbers according to NIST 
Special Publication 811(incorporated by reference in Sec.86.1).

[70 FR 34619, June 14, 2005, as amended at 75 FR 68459, Nov. 8, 2010]



Sec.86.1905  How does this program work?

    (a) You must test in-use engines from the families we select. We may 
select the following number of engine families for testing, except as 
specified in paragraph (b) of this section:
    (1) We may select up to 25 percent of your engine families in any 
calendar year, calculated by dividing the number of engine families you 
certified in the model year corresponding to the calendar year by four 
and rounding to the nearest whole number. We will consider only engine 
families with annual U.S.-directed production volumes above 1,500 units 
in calculating the number of engine families subject to testing each 
calendar year under the annual 25 percent engine family limit. In 
addition, for model year 2007 through 2009, identical engine families 
that are split into two subfamilies under Sec.86.007-15(m)(9) will 
count as only one engine family. If you have only three or fewer 
families that each exceed an annual U.S.-directed production volume of 
1,500 units, or if you have no engine families above this limit, we may 
select one engine family per calendar year for testing.
    (2) Over any four-year period, we will not select more than the 
average number of engine families that you have certified over that 
four-year period (the model year when the selection is made and the 
preceding three model years), based on rounding the average value to the 
nearest whole number.
    (b) If there is clear evidence of a nonconformity with regard to an 
engine family, we may select that engine family without counting it as a 
selected engine family under paragraph (a) of this section. We will 
consult with you in reaching a conclusion whether clear evidence of a 
nonconformity exists for any engine family. In general, there is clear 
evidence of a nonconformity regarding an engine family under this 
subpart in any of the following cases:
    (1) The engine family was not remedied but is a carry-over from an 
engine family you tested under this subpart and was subsequently 
remedied based at least in part on the Phase 1 or Phase 2 testing 
outcomes described in Sec.86.1915.
    (2) The engine family was not remedied but is a carry-over from an 
engine family that was remedied based on an EPA in-use testing program.
    (c) We may select any individual engine family for testing, 
regardless of its production volume, as long as we do not select more 
than the number of engine families described in paragraph (a) of this 
section. We may select an engine family from the current model year or 
any previous model year, except that we will not select any engine 
families from model years before 2007 beginning in the following 
calendar years:
    (1) 2007 for all emissions testing other than PM testing.
    (2) 2011 for PM testing.
    (d) You must complete all the required testing and reporting under 
this subpart within 18 months after we direct you to test a particular 
engine family. We will typically select engine families for testing and 
notify you in writing by June 30 of the applicable calendar year. You 
may ask for up to six months longer to complete Phase 2

[[Page 1137]]

testing if there is a reasonable basis for needing more time. In very 
unusual circumstances you may request an additional six months to 
complete Phase 2 testing.
    (e) If you make a good-faith effort to access enough test vehicles 
to complete Phase 1 or Phase 2 testing requirements under this subpart 
for an engine family, but are unable to do so, you must ask us either to 
modify the testing requirements for the selected engine family or, in 
the case of Phase 1 testing, to select a different engine family.
    (f) After you complete the in-use testing requirements for an engine 
family that we selected for testing in a given calendar year, we may 
select that same family in a later year to evaluate the engine family's 
compliance closer to the end of its useful life. This would count as an 
additional engine-family selection under paragraph (a) of this section, 
except as described in paragraph (b) of this section.
    (g) For any communication related to this subpart, contact the 
Engine Programs Group Manager (6405-J), U.S. Environmental Protection 
Agency, 1200 Pennsylvania Ave., NW., Washington, DC 20460.

[70 FR 34619, June 14, 2005, as amended at 73 FR 13450, Mar. 13, 2008; 
75 FR 68459, Nov. 8, 2010]



Sec.86.1908  How must I select and screen my in-use engines?

    (a) Once we direct you to do testing under this subpart, you must 
make arrangements to select test vehicles and engines that meet the 
following criteria:
    (1) The engines must be representative of the engine family.
    (2) The usage of the vehicles must be representative of typical 
usage for the vehicles' particular application.
    (3) The vehicles come from at least two independent sources.
    (4) The key vehicle/engine systems (e.g., power train, drive train, 
emission control) have been properly maintained and used.
    (5) The engines have not been tampered with, rebuilt or undergone 
major repair that could be expected to affect emissions.
    (6) The engines have not been misfueled. For example, an engine may 
be considered misfueled if operated on a biodiesel fuel blend that is 
either not listed as allowed or otherwise indicated to be an 
unacceptable fuel in the vehicle's owner or operator manual.
    (7) The engines do not have an illuminated MIL or stored OBD trouble 
code that lead you to reject the vehicle from the test program as 
described in Sec.86.1910(b)(2).
    (8) The vehicles are likely to operate for at least three hours 
(excluding idle) over a complete shift-day, as described in Sec.
86.1910(g).
    (9) The vehicles have not exceeded the applicable useful life, in 
miles or years (see subpart A of this part); you may otherwise not 
exclude engines from testing based on their age or mileage.
    (10) The vehicle has appropriate space for safe and proper mounting 
of the PEMS equipment.
    (b) You must keep any records of a vehicle's maintenance and use 
history you obtain from the owner or operator, as required by Sec.
86.1925. You must report the engine's maintenance and use history and 
information related to the OBD system, as described in Sec.86.1920.
    (c) You must notify us before rejecting a candidate vehicle for 
reasons other than failing to meet the acceptance criteria in paragraph 
(a) of this section. A candidate vehicle is any prospective vehicle you 
have identified to potentially fulfill your testing requirements under 
this subpart. Include your reasons for rejecting each vehicle. If an 
owner declines to participate in the test program, you may reject the 
vehicle without prior notification. Such a rejection must be reported as 
described in Sec.86.1920. We may allow you to replace the rejected 
vehicle with another candidate vehicle to meet your testing requirements 
for the specific engine family.
    (d) You must report when, how, and why you reject candidate 
vehicles, as described in Sec.86.1920.



Sec.86.1910  How must I prepare and test my in-use engines?

    (a) You must limit maintenance to what is in the owners manual for 
engines with that amount of service and

[[Page 1138]]

age. For anything we consider an adjustable parameter (see Sec. Sec.
86.094-21(b)(1)(ii) and 86.094-22(e)), you may adjust that parameter 
only if it is outside of its adjustable range. You must then set the 
adjustable parameter to the mid-point of its adjustable range or your 
recommended setting, unless we approve your request to do otherwise. You 
must receive permission from us before adjusting anything not considered 
to be an adjustable parameter. You must keep records of all maintenance 
and adjustments, as required by Sec.86.1925. You must send us these 
records, as described in Sec.86.1920(b)(3)(x), unless we instruct you 
not to send them.
    (b) You may treat a vehicle with an illuminated MIL or stored 
trouble code as follows:
    (1) If the length of MIL illumination or trouble code storage is 
consistent with proper maintenance and use, either test the prospective 
test vehicle as received or repair the vehicle before testing. If you 
elect to repair the vehicle/engine, but ultimately determine that 
repairs cannot be completed in a timely manner, you may reject the 
vehicle from the test program and replace it with another vehicle. If 
you repair or reject the vehicle, you must describe the MIL or trouble 
code information in your report under Sec.86.1920.
    (2) If the length of MIL illumination or trouble code storage is 
inconsistent with proper maintenance and use, either test the 
prospective test vehicle as received, repair the vehicle before testing, 
or reject the vehicle from the test program and replace it with another 
vehicle. If you repair or reject the vehicle, you must describe the MIL 
or trouble code information in your report under Sec.86.1920.
    (3) If a MIL is illuminated or a trouble code is set during an in-
use test, do one of the following:
    (i) Stop the test, repair the vehicle, and restart the testing. In 
this case, only the portion of the full test results without the MIL 
illuminated or trouble code set would be used in the vehicle-pass 
determination as described in Sec.86.1912. Describe the MIL or trouble 
code information in your report under Sec.86.1920.
    (ii) Stop the test, repair the vehicle, and initiate a new test. In 
this case, only the post-repair test results would be used in the 
vehicle-pass determination as described in Sec.86.1912. Describe the 
MIL or trouble code information in your report under Sec.86.1920.
    (iii) If three hours of non-idle operation have been accumulated 
prior to the time a MIL is illuminated or trouble code set, stop the 
test and use the accumulated test results in the vehicle-pass 
determination as described in Sec.86.1912.
    (iv) If three hours of non-idle operation have not been accumulated 
prior to the time a MIL is illuminated or trouble code is set, and you 
elect to repair the vehicle/engine, but ultimately determine that 
repairs cannot be completed in a timely manner, you may reject the 
vehicle from the test program and replace it with another vehicle. If 
you repair or reject the vehicle, you must describe the MIL or trouble 
code information in your report under Sec.86.1920.
    (c) Use appropriate fuels for testing, as follows:
    (1) You may use any diesel fuel that meets the specifications for 
No. 2-D S500 or No. 2-D S15 in ASTM D 975 (incorporated by reference in 
Sec.86.1), as required in the calendar year that in-use testing 
occurs.
    (2) You may use any biodiesel fuel blend that is either expressly 
allowed or not otherwise indicated as an unacceptable fuel in the 
vehicle's owner or operator manual or in the engine manufacturer's 
published fuel recommendations.
    (3) You may drain a prospective test vehicle's fuel tank(s) and 
refill the tank(s) with diesel fuel conforming to ASTM D 975 
specifications described in paragraph (c)(1) of this section.
    (4) Any fuel that is added to the fuel tank(s) of a prospective test 
vehicle, or during an in-use test, must be purchased at a local retail 
establishment near the site of vehicle procurement or screening, or 
along the test route. Alternatively, the fuel may be drawn from a 
central fueling source, provided that the fuel used is representative of 
that which is commercially available in the area where the vehicle is 
operated.

[[Page 1139]]

    (5) No post-refinery fuel additives are allowed, except that one or 
more specific fuel additives may be used during in-use testing if you 
can document that the owner/operator of the prospective test vehicle has 
a history of normally using the fuel treatment(s), and the fuel 
additive(s) is not prohibited in the vehicle's owner or operator manual 
or in the engine manufacturer's published fuel-additive recommendations.
    (6) You may take fuel samples from test vehicles to ensure that 
appropriate fuels were used during in-use testing. If a vehicle fails 
the vehicle-pass criteria and you can show that an inappropriate fuel 
was used during the failed test, that particular test may be voided. You 
may drain the vehicle's fuel tank(s) and refill the tank(s) with diesel 
fuel conforming to the ASTM D 975 specifications described in paragraph 
(c)(1) of this section. You must report any fuel tests that are the 
basis of voiding a test in your report under Sec.86.1920.
    (d) You must test the selected engines while they remain installed 
in the vehicle. Use portable emission sampling equipment and field-
testing procedures referenced in Sec.86.1375. Measure emissions of 
THC, NMHC (by any method specified in 40 CFR part 1065, subpart J), CO, 
NOX, PM (as appropriate), and CO2. Measure or 
determine O2 emissions using good engineering judgment.
    (e) For Phase 1 testing, you must test the engine under conditions 
reasonably expected to be encountered during normal vehicle operation 
and use consistent with the general NTE requirements described in Sec.
86.1370-2007(a). For the purposes of this subpart, normal operation and 
use would generally include consideration of the vehicle's normal routes 
and loads (including auxiliary loads such as air conditioning in the 
cab), normal ambient conditions, and the normal driver.
    (f) For Phase 2 testing, we may give specific directions, as 
described in Sec.86.1915(c)(2).
    (g) Once an engine is set up for testing, test the engine for at 
least one shift-day. To complete a shift-day's worth of testing, start 
sampling at the beginning of a shift and continue sampling for the whole 
shift, subject to the calibration requirements of the portable emissions 
measurement systems. A shift-day is the period of a normal workday for 
an individual employee. If the first shift-day of testing does not 
involve at least 3 hours of accumulated non-idle operation, repeat the 
testing for a second shift-day and report the results from both days of 
testing. If the second shift-day of testing also does not result in at 
least 3 hours of accumulated non-idle operation, you may choose whether 
or not to continue testing with that vehicle. If after two shift-days 
you discontinue testing before accumulating 3 hours of non-idle 
operation on either day, evaluate the valid NTE samples from both days 
of testing as described in Sec.86.1912 and include the data in the 
reporting and record keeping requirements specified in Sec. Sec.
86.1920 and 1925. Count the engine toward meeting your testing 
requirements under this subpart and use the data for deciding whether 
additional engines must be tested under the applicable Phase 1 or Phase 
2 test plan.
    (h) You have the option to test longer than the two shift-day period 
described in paragraph (g) of this section.
    (i) You may count a vehicle as meeting the vehicle-pass criteria 
described in Sec.86.1912 if a shift day of testing or two-shift days 
of testing (with the requisite non-idle/idle operation time as in 
paragraph (g) of this section), or if the extended testing you elected 
under paragraph (h) of this section does not generate a single valid NTE 
sampling event, as described in Sec.86.1912(b). Count the vehicle 
towards meeting your testing requirements under this subpart.
    (j) You may ask us to waive measurement of particular emissions if 
you can show that in-use testing for such emissions is not necessary.

Sec.86.1912  How do I determine whether an engine meets the vehicle-
pass criteria?

    In general, the average emissions for each regulated pollutant must 
remain at or below the NTE threshold in paragraph (a) of this section 
for at least 90 percent of the valid NTE sampling

[[Page 1140]]

events, as defined in paragraph (b) of this section. For 2007 through 
2009 model year engines, the average emissions from every NTE sampling 
event must also remain below the NTE thresholds in paragraph (g)(2) of 
this section. Perform the following steps to determine whether an engine 
meets the vehicle-pass criteria:
    (a) Determine the NTE threshold for each pollutant subject to an NTE 
standard by adding all three of the following terms and rounding the 
result to the same number of decimal places as the applicable NTE 
standard:
    (1) The applicable NTE standard.
    (2) The in-use compliance testing margin specified in Sec.86.007-
11(h), if any.
    (3) An accuracy margin for portable in-use equipment when testing is 
performed under the special provisions of Sec.86.1930, depending on 
the pollutant, as follows:
    (i) NMHC: 0.17 g/hp[middot]hr.
    (ii) CO: 0.60 g/hp[middot]hr.
    (iii) NOX: 0.50 g/hp[middot]hr.
    (iv) PM: 0.10 g/hp[middot]hr.
    (v) NOX + NMHC: 0.67 g/hp[middot]hr.
    (4) Accuracy margins for portable in-use equipment when testing is 
not performed under the special provisions of Sec.86.1930 for 2007 
through 2009 model year engine families that are selected for testing in 
any calendar year as follows:
    (i) NMHC using the emission calculation method specified in 40 CFR 
1065.650(a)(1): 0.02 g/hp[middot]hr.
    (ii) NMHC using the emission calculation method specified in 40 CFR 
1065.650(a)(3): 0.01 g/hp[middot]hr.
    (iii) NMHC using an alternative emission calculation method we 
approve under 40 CFR 1065.915(d)(5)(iv): 0.01 g/hp[middot]hr.
    (iv) CO using the emission calculation method specified in 40 CFR 
1065.650(a)(1): 0.5 g/hp[middot]hr.
    (v) CO using the emission calculation method specified in 40 CFR 
1065.650(a)(3): 0.25 g/hp[middot]hr.
    (vi) CO using an alternative emission calculation method we approve 
under 40 CFR 1065.915(d)(5)(iv): 0.25 g/hp[middot]hr.
    (vii) NOX using the emission calculation method specified 
in 40 CFR 1065.650(a)(1): 0.45 g/hp[middot]hr.
    (viii) NOX using the emission calculation method 
specified in 40 CFR 1065.650(a)(3): 0.15 g/hp[middot]hr.
    (ix) NOX using an alternative emission calculation method 
we approve under 40 CFR 1065.915(d)(5)(iv): 0.15 g/hp[middot]hr.
    (x) NOX + NMHC using the emission calculation method 
specified in 40 CFR 1065.650(a)(1): 0.47 g/hp[middot]hr.
    (xi) NOX + NMHC using the emission calculation method 
specified in 40 CFR 1065.650(a)(3): 0.16 g/hp[middot]hr.
    (xii) NOX + NMHC using an alternative emission 
calculation method we approve under 40 CFR 1065.915(d)(5)(iv): 0.16 g/
hp[middot]hr.
    (xiii) PM: 0.006 g/hp[middot]hr.
    (5) Accuracy margins for portable in-use equipment when testing is 
not performed under the special provisions of Sec.86.1930 for 2010 or 
later model year engines families that are selected for testing in any 
calendar year as follows:
    (i) NMHC using any emission calculation method specified in 40 CFR 
1065.650(a) or an alternative emission calculation method we approve 
under 40 CFR 1065.915(d)(5)(iv): 0.01 g/hp[middot]hr.
    (ii) CO using any emission calculation method specified in 40 CFR 
1065.650(a) or an alternative emission calculation method we approve 
under 40 CFR 1065.915(d)(5)(iv): 0.25 g/hp[middot]hr.
    (iii) NOX using any emission calculation method specified 
in 40 CFR 1065.650(a) or an alternative emission calculation method we 
approve under 40 CFR 1065.915(d)(5)(iv): 0.15 g/hp[middot]hr.
    (iv) PM: 0.006 g/hp[middot]hr.
    (b) For the purposes of this subpart, a valid NTE sampling event 
consists of at least 30 seconds of continuous operation in the NTE 
control area. An NTE event begins when the engine starts to operate in 
the NTE control area and continues as long as engine operation remains 
in this area (see Sec.86.1370). When determining a valid NTE sampling 
event, exclude all engine operation in approved NTE limited testing 
regions under Sec.86.1370-2007(b)(6) and any approved NTE deficiencies 
under Sec.86.007-11(a)(4)(iv). Engine operation in the NTE control 
area of less than 30 contiguous seconds does not count as a valid NTE 
sampling event; operating periods of less than 30 seconds in the NTE 
control area, but outside of any

[[Page 1141]]

allowed deficiency area or limited testing region, will not be added 
together to make a 30 second or longer event. Exclude any portion of a 
sampling event that would otherwise exceed the 5.0 percent limit for the 
time-weighted carve-out defined in Sec.86.1370-2007(b)(7). For EGR-
equipped engines, exclude any operation that occurs during the cold-
temperature operation defined by the equations in Sec.86.1370-
2007(f)(1).
    (c) Calculate the average emission level for each pollutant over 
each valid NTE sampling event as specified in 40 CFR part 1065, subpart 
G, using each NTE event as an individual test interval. This should 
include valid NTE events from all days of testing.
    (d) If the engine has an open crankcase, account for these emissions 
by adding 0.00042 g/hp[middot]hr to the PM emission result for every NTE 
event.
    (e) Calculate a time-weighted vehicle-pass ratio (Rpass) 
for each pollutant. To do this, first sum the time from each valid NTE 
sampling event whose average emission level is at or below the NTE 
threshold for that pollutant, then divide this value by the sum of the 
engine operating time from all valid NTE events for that pollutant. 
Round the resulting vehicle-pass ratio to two decimal places.
    (1) Calculate the time-weighted vehicle-pass ratio for each 
pollutant as follows:
[GRAPHIC] [TIFF OMITTED] TR25OC16.041

Where:

npass = the number of valid sampling events for which the 
          average emission level is at or below the NTE threshold.
ntotal = the total number of valid NTE sampling events.

    (2) For both the numerator and the denominator of the vehicle-pass 
ratio, use the smallest of the following values for determining the 
duration, t, of any NTE sampling event:
    (i) The measured time in the NTE zone that is valid for an NTE 
sampling event.
    (ii) 600 seconds.
    (iii) 10 times the length of the shortest valid NTE sampling event 
for all testing with that engine.
    (f) The following example illustrates how to select the duration of 
NTE sampling events for calculations, as described in paragraph (f) of 
this section:

    (g) Engines meet the vehicle-pass criteria under this section if 
they meet both of the following criteria:
    (1) The vehicle-pass ratio calculated according to paragraph (e) of 
this section must be at least 0.90 for each pollutant.
    (2) For model year 2007 through 2009 engines, emission levels from 
every valid NTE sampling event must be less than 2.0 times the NTE 
thresholds calculated according to paragraph (a) of this section for all 
pollutants, except that engines certified to a NOX FEL at

[[Page 1142]]

or below 0.50 g/hp[middot]hr may meet the vehicle-pass criteria for 
NOX if measured NOX emissions from every valid NTE 
sample are less than either 2.0 times the NTE threshold for 
NOX or 2.0 g/hp[middot]hr, whichever is greater.

[81 FR 73998, Oct. 25, 2016]



Sec.86.1915  What are the requirements for Phase 1 and Phase 2 
testing?

    For all selected engine families, you must do the following:
    (a) To determine the number of engines you must test from each 
selected engine family under Phase 1 testing, use the following 
criteria:
    (1) Start by measuring emissions from five engines using the 
procedures described in Sec.86.1375. If all five engines comply fully 
with the vehicle-pass criteria in Sec.86.1912 for all pollutants, you 
may stop testing. This completes your testing requirements under this 
subpart for the applicable calendar year for that engine family.
    (2) If one of the engines tested under paragraph (a)(1) of this 
section fails to comply fully with the vehicle-pass criteria in Sec.
86.1912 for one or more pollutants, test one more engine. If this 
additional engine complies fully with the vehicle-pass criteria in Sec.
86.1912 for all pollutants, you may stop testing. This completes your 
testing requirements under this subpart for the applicable calendar year 
for that engine family.
    (3) If your testing results under paragraphs (a)(1) and (2) of this 
section do not satisfy the criteria for completing your testing 
requirements under those paragraphs for all pollutants, test four 
additional engines so you have tested a total of ten engines.
    (4) An engine that fails to fully comply with the vehicle-pass 
criteria in Sec.86.1912 for any pollutant does not comply with the 
vehicle-pass criteria in Sec.86.1912 for the purposes of determining 
the number of engines to test from each selected engine family under 
this paragraph.
    (b) For situations where a total of ten engines must be tested under 
paragraph (a)(3) of this section, the results of Phase 1 testing lead to 
the following outcomes:
    (1) If at least eight of the ten engines comply fully with the 
vehicle-pass criteria in Sec.86.1912 for all pollutants, you may stop 
testing. This completes your testing requirements under this subpart for 
the applicable calendar year for that engine family.
    (2) If six or seven vehicles from the Phase 1 sample of test 
vehicles comply fully with the vehicle-pass criteria in Sec.86.1912 
for all pollutants, then you must engage in follow-up discussions with 
us to determine whether any further testing (including Phase 2 testing), 
data submissions, or other actions may be warranted.
    (3) If fewer than six of the ten engines tested under paragraph (a) 
of this section comply fully with the vehicle-pass criteria in Sec.
86.1912 for all pollutants, we may require you to initiate Phase 2 
testing, as described in paragraph (c) of this section.
    (4) You may under any circumstances elect to conduct Phase 2 testing 
following the completion of Phase 1 testing. All the provisions of 
paragraph (c) of this section apply to this Phase 2 testing.
    (c) If you perform Phase 2 testing for any reason, test your engines 
as follows:
    (1) You must test ten additional engines using the test procedures 
described in Sec.86.1375, unless we require you to test fewer 
vehicles.
    (2) We may give you any of the following additional directions in 
selecting and testing engines:
    (i) We may require you to select a certain subset of your engine 
family. This may include, for example, engines within a specific power 
range, engines used in particular applications, or engines installed in 
vehicles from a particular manufacturer.
    (ii) We may direct you to test engines in a way that simulates the 
type of driving and ambient conditions associated with high emissions 
experienced during Phase 1 testing.
    (iii) We may direct you to test engines in a specific state or any 
number of contiguous states.
    (iv) We may direct you to select engines from the same sources used 
for previous testing, or from different sources.
    (v) We may require that you complete your testing and reporting 
under Phase 2 within a certain period. This period may not be shorter 
than three

[[Page 1143]]

months and must allow a reasonable amount of time to identify and test 
enough vehicles. We would generally expect this testing to be completed 
within the overall time period specified in Sec.86.1905(d).



Sec.86.1917  How does in-use testing under this subpart relate to
the emission-related warranty in Section 207(a)(1) of the Clean
Air Act?

    (a) An exceedance of the NTE found through the in-use testing 
program under this subpart is not by itself sufficient to show a breach 
of warranty under Clean Air Act section 207(a)(1) (42 U.S.C. 
7541(a)(1)). A breach of warranty would also require one of the 
following things:
    (1) That, at the time of sale, the engine or vehicle was designed, 
built, and equipped in a manner that does not conform in all material 
respects reasonably related to emission controls to the engine as 
described in the application for certification and covered by the 
certificate; or
    (2) A defect in materials or workmanship of a component causes the 
vehicle or engine to fail to conform to the applicable regulations for 
its useful life.
    (b) To the extent that in-use NTE testing does not reveal such a 
material deficiency at the time of sale in the design or manufacture of 
an engine compared with the certified engine, or a defect in the 
materials and workmanship of a component or part, test results showing 
an exceedance of the NTE by itself would not show a breach of the 
warranty under 42 U.S.C. 7541(a)(1).



Sec.86.1920  What in-use testing information must I report to EPA?

    (a) Send us electronic reports at [email protected] using an approved 
information format. If you want to use a different format, send us a 
written request with justification.
    (b) Within 45 days after the end of each calendar quarter, send us 
reports containing the test data from each engine for which testing was 
completed during the calendar quarter. Alternatively, you may separately 
send us the test data within 30 days after you complete testing for an 
engine. If you request it, we may allow additional time to send us this 
information. Once you send us information under this section, you need 
not send that information again in later reports. Prepare your test 
reports as follows:
    (1) For each engine family, describe how you recruited vehicles. 
Describe how you used any criteria or thresholds to narrow your search 
or to screen individual vehicles.
    (2) Include a summary of the candidate vehicles you have rejected 
and the reasons you rejected them, whether you base the rejection on the 
criteria in Sec.86.1908(a) or anything else. If you rejected a 
candidate vehicle due to misfueling, included the results of any fuel 
sample tests.
    (3) For the test vehicle, include the following background 
information:

    (vii) The vehicle's maintenance and use history.
    (viii) The known status history of the vehicle's OBD system and any 
actions the owner or operator took to address OBD trouble codes or MIL 
illumination over the vehicle's lifetime.
    (ix) Any OBD codes or MIL illumination that occur after you accept 
the vehicle for in-use testing under this subpart.
    (x) Any steps you take to maintain, adjust, modify, or repair the 
vehicle or its engine to prepare for or continue testing, including 
actions to address OBD trouble codes or MIL illumination. Include any 
steps you took to drain and refill the vehicle's fuel tank(s) to correct 
misfueling, and the results of any fuel test conducted to identify 
misfueling.
    (4) For each test, include the following data and measurements:
    (i) The date and time of testing, and the test number.

[[Page 1144]]

    (ii) Shift-days of testing (see Sec.86.1910 (g)), duration of 
testing, and the total hours of non-idle operation.
    (iii) Route and location of testing. You may base this description 
on the output from a global-positioning system.
    (iv) The steps you took to ensure that vehicle operation during 
testing was consistent with normal operation and use, as described in 
Sec.86.1910(e).
    (v) Fuel test results, if fuel was tested under Sec.86.1908 or 
Sec.86.1910.
    (vi) The vehicle's mileage at the start of the test. Include the

    (ix) Average emissions for each pollutant over each valid NTE event. 
Describe the method you used to determine NMHC as specified in 40 CFR 
part 1065, subpart J. See appendix I of this subpart for an example of 
graphically summarizing NTE emission results.
    (x) Exhaust-flow measurements.
    (xi) Vehicle-pass ratios (see Sec.86.1912(d)).
    (xii) Recorded one-hertz test data, including, but not limited to, 
the following parameters:
    (A) Ambient temperature.
    (B) Ambient pressure.
    (C) Ambient humidity.
    (D) Altitude.
    (E) Emissions of THC, NMHC, CO, CO2 or O2, and 
NOX (as appropriate). Report results for PM if it was 
measured in a manner that provides one-hertz test data. Report results 
for CH4 if it was measured and used to determine NMHC.
    (F) Differential back-pressure of any PEMS attachments to vehicle 
exhaust.
    (G) Exhaust flow.
    (H) Exhaust aftertreatment temperatures, if the engine meets the 
specifications of Sec.86.1370-2007(g).
    (I) Engine speed.
    (J) Engine brake torque.

    (5) For each engine family, identify the applicable requirements, as 
follows:
    (i) The applicable NTE thresholds.
    (ii) Vehicle and engine information needed to identify the limited 
testing regions under Sec.86.1370-2007(b)(6) and (7).
    (iii) Vehicle and engine information needed to identify any approved 
NTE deficiencies under Sec.86.007-11(a)(4)(iv).
    (6) Include the following summary information after you complete 
testing with the engine:
    (i) State whether the engine meets the vehicle-pass criteria in 
Sec.86.1912(f).
    (ii) Identify how many engines you have tested from the applicable 
engine family and how many engines still need to be tested.
    (iii) Identify how many engines from an engine family have passed 
the vehicle-pass criteria and the number that have failed the vehicle-
pass criteria (see Sec.86.1912(f)).
    (iv) If possible, state the outcome of Phase 1 testing for the 
engine family based on the criteria in Sec.86.1915(b).
    (c) In your reports under this section, you must do all the 
following:
    (1) Include results from all emission testing required under this 
subpart.
    (2) Describe if any testing or evaluations were conducted to 
determine why a vehicle failed the vehicle-pass criteria in Sec.

Sec.86.1930  What special provisions apply from 2005 through 2010?

    (a) We may direct you to test engines under this subpart for 
emissions other than PM in 2005 and 2006, and for PM emissions in 2007 
through 2010. In those interim periods, all the provisions of this 
subpart apply, except as specified in this paragraph (a). You may apply 
the exceptions identified in this section for both years of the 
applicable years for emissions other than PM. You may omit testing and 
reporting in two of the four applicable years for PM emissions.
    (1) We will select engine families for testing of emissions other 
than PM only when the manufacturer's Statement of Compliance 
specifically describes the family as being designed to comply with NTE 
requirements.
    (2) We will not direct you to do the Phase 2 testing in Sec.
86.1915(c), regardless of measured emission levels.
    (3) For purposes of calculating the NTE thresholds under Sec.
86.1912(a) for any 2006 and earlier model year engine that is not 
subject to the emission standards in Sec.86.007-11, determine the 
applicable NTE standards as follows:
    (i) If any numerical NTE requirements specified in the terms of any 
consent decree apply to the engine family, use those values as the NTE 
standards for testing under this subpart.
    (ii) If a numerical NTE requirement is not specified in a consent 
decree for the engine family, the NTE standards are 1.25 times the 
applicable FELs or the applicable emission standards specified in Sec.
86.004-11(a)(1) or Sec.86.098-11(a)(1).
    (4) In the report required in Sec.86.1920(b), you must submit the 
deficiencies and limited testing region reports (see Sec. Sec.86.007-
11(a)(4)(iv) and 86.1370-2007(b)(6) and (7)) for 2006 and earlier model 
year engines tested under this section.
    (5) You must notify the Designated Compliance Officer by September 
30,

[[Page 1146]]

2010 whether or not you will submit test reports for PM emissions for 
each of the four years from 2007 through 2010. See 40 CFR 1068.30 for 
the contact information for the Designated Compliance Officer.
    (6) You must submit reports by the deadlines specified in paragraph 
(b) of this section.
    (b) The following deadlines apply for reporting test results under 
this subpart:
    (1) You must complete all the required testing and reporting under

 Sec. Appendix III to Part 86--Constant Volume Sampler Flow Calibration

    The following calibration procedure outlines the equipment, the test 
setup configuration, and the various parameters which must be measured 
to establish the flow rate of the constant volume sampler pump. All the 
parameters related to the pump are simultaneously measured with the 
parameters related to a flowmeter which is connected in series with the 
pump. The calculated flow rate (ft \3\/rev@ pump inlet absolute pressure 
and temperature) can then be plotted versus a correlation function which 
is the value of a specific combination of pump parameters. The linear 
equation which relates the pump flow and the correlation function is 
then determined. In the event that a CVS has a multiple speed drive, a 
calibration for each range should be performed.
    This calibration procedure is based on the measurement of the 
absolute values of the pump and flowmeter parameters that relate the 
flow rate at each point. Three conditions must be maintained to assure 
the accuracy and integrity of the calibration curve. First, the pump 
pressures should be measured at taps on the pump rather than at the 
external piping on the pump inlet and outlet. Pressure taps that are 
mounted at the top and bottom center of the pump drive headplate are 
exposed to the actual pump cavity pressures, and therefore reflect the 
absolute pressure differentials. Secondly, temperature stability must be 
maintained during the calibration. The laminar flowmeter is sensitive to 
inlet temperature oscillations which cause the data points to be 
scattered. Gradual changes (2 [deg]F) in 
temperature are acceptable as long as they occur over a period of 
several minutes. Finally, all connections between the flowmeter and the 
CVS pump must be absolutely void of any leakage.
    During a CVS emissions test the measurement of these same pump 
parameters enables the user to calculate the flow rate from the 
calibration equation.
    After the calibration curve has been obtained, a verification test 
of the entire system can be performed by injecting a known mass of gas 
into the system and comparing the mass indicated by the system to the 
true mass injected. An indicated error does not necessarily mean that 
the calibration is wrong, since other factors can influence the accuracy 
of the system.

Equipment:

    The following list of equipment will be needed to perform this 
calibration procedure. Figure 1 illustrates a typical equipment 
arrangement used for calibration. All of the equipment involved should 
conform to the range and accuracy as specified in Figure 1.

Equipment List:

    1. LFE--Laminar Flowmeter
    2. Micromanometer
    3. Thermometer
    4. Timer
    5. U-Tube Manometers
    6. Temperature Indicator with type J Thermocouples
    7. A variable flow restrictor with appropriate piping to connect the 
CVS pump and LFE.
    After the system has been connected as shown in Figure 1, set the 
variable restrictor in the wide open position and run the CVS pump for 
twenty minutes. Record the calibration data.

----------------------------------------------------------------------------------------------------------------
Note: The fluid level in the manometer tube should stabilize before the reading is made and the elapsed time for
  revolution counting should be greater than 120 seconds.

    Reset the restrictor valve to a more restricted condition in an 
increment of pump inlet depression (about 4 H2O) 
that will yield a minimum of six data points for the total calibration.
    Allow the system to stabilize for 3 minutes and repeat the data 
acquisition.

Data Analysis:

    The data recorded during the calibration are to be used in the 
following calculations.
    1. The air flow rate at each test point is calculated in standard 
cubic feet per minute (Qs) from the flowmeter data using the 
manufacturer's prescribed method.
    2. The air flow rate is then converted to pump flow, Vo, in cubic 
feet per revolution at absolute pump inlet temperature and pressure.

Vo = Qs/n x Tp/530 x 29.92/Pp

where:

Qs = Meter air flow rate in standard cubic feet per minute (flowmeter 
          standard conditions are 70 [deg]F, 29.92 ``Hg).
n = Pump speed in revolutions per minute.
Pp = Absolute pump inlet pressure, in (``Hg).
Pp = PB-PPI (SP.GR./13.57), Tp = PTI + 
          460.

    3. The correlation function at each test point is then calculated 
from the calibration data, as follows:
[GRAPHIC] [TIFF OMITTED] TR06OC93.139

[Delta]Pp = The pressure differential from pump inlet to pump 
          outlet in (``Hg).

[Delta]Pp = Pe-Pp

Pe = Absolute pump outlet pressure, in (``Hg).

Pp = PB + PPO (Sp. Gr./13.57)
    See Sec.86.177-22 for other definitions.
    4. A linear least squares fit is performed to generate the 
calibration equations which have the forms

Vo = Do-M(Xo)

n = A-B(Pp)

    Do, M, A, and B are the slope-intercept constants describing the 
lines.
    A CVS system that has multiple speeds should be calibrated on each 
speed used. The calibration curves generated for the ranges will be 
approximately parallel and the intercept values, Do, will 
increase as the pump flow range decreases.

[[Page 1196]]

[GRAPHIC] [TIFF OMITTED] TR06OC93.196

    If the calibration has been performed carefully, the calculated 
Vo values from the equation will be within .50% of the measured value of Vo. Values of M 
will vary from one pump to another, but values of Do for 
pumps of the same make, model, and range should agree within 3 percent of each other. Particulate influx from use 
will cause the pump slip to decrease as reflected by lower values for M. 
Calibrations should be performed at 0, 30, 100, 200, 400, etc. hours of 
pump operation to assure the stability of the pump slip rate. Analysis 
of mass injection data will also reflect pump slip stability.

CVS System Verification:

    The following technique can be used to verify that the CVS and 
analytical instruments can accurately measure a mass of gas that has 
been injected into the system.
    1. Obtain a small cylinder that has been charged with pure propane 
or carbon monoxide gas (caution--carbon monoxide is poisonous!). 
Critical flow orifice devices can also be used for constant flow 
metering.
    2. Determine a reference cylinder weight to the nearest 0.01 gram.
    3. Operate the CVS in the normal manner and release a quantity of 
pure propane or

[[Page 1197]]

carbon monoxide into the system during the sampling period.
    4. The calculations of Sec.86.177-22 are performed in a normal way 
except, in the case of propane, the density of propane (17.30 grams/cu./
ft./carbon atom) is used in place of the density of exhaust 
hydrocarbons. In the case of carbon monoxide, the density of 32.97 
grams/cu. ft. is used.
    5. The gravimetric mass is subtracted from the CVS measured mass and 
then divided by the gravimetric mass to determine the percent accuracy 
of the system.
    6. The cause for any discrepancy greater than 2 percent should be found and corrected. The following 
list of parametric errors may assist the operator in locating the cause 
of large errors.
    Positive Error (Indication is higher than true value):
    1. Calculated Vo is greater than actual Vo.
    a. Original calibration in error.
    2. Pump inlet temperature recorder is reading low. A 6 [deg]F. 
discrepancy will give a 1 percent error.
    3. Pump inlet pressure indicator is reading high. A 3.5 in. 
H2O high reading will give 1 percent error.
    4. Background concentration reading is too low. Check analyzer zero. 
Check leakage at floor inlet.
    5. Analyzer is reading high. Check span.
    6. Barometer reading is in error (too high). Barometric pressure 
reading should be gravity and temperature corrected.
    7. Revolution counter is reading high (Check pump speed and 
counters.)
    8. Mixture is stratified causing the sample to be higher than the 
average concentration in the mixture. Negative Error (Indication is 
lower than true value):
    1. Calculated Vo is less than actual Vo.
    a. Original calibration in error.
    b. Pump clearances decreased due to influx of some surface adherent 
material. Recalibration may be needed.
    2. Pump inlet temperature recorder is reading high.
    3. Pump inlet pressure indicator is reading low.
    4. Background concentration reading is too high.
    5. Analyzer is reading low.
    6. Barometer reading is in error (too low).
    7. Revolution counter is reading low.
    8. There is a leak into the sampling system. Pressure check the 
lines and fittings on the intake side of sample transfer pumps on both 
the CVS and analyzer console.

        Sec. Appendix VII to Part 86--Standard Bench Cycle (SBC)

    1. The standard bench aging durability procedures [Ref. Sec.
86.1823-08(d)] consist of aging a catalyst-oxygen-sensor system on an 
aging bench which follows the standard bench cycle (SBC) described in 
this appendix.
    2. The SBC requires use of an aging bench with an engine as the 
source of feed gas for the catalyst.
    3. The SBC is a 60-second cycle which is repeated as necessary on 
the aging bench to conduct aging for the required period of time. The 
SBC is defined based on the catalyst temperature, engine air/fuel (A/F) 
ratio, and the amount of secondary air injection which is added in front 
of the first catalyst.

                      Catalyst Temperature Control

    1. Catalyst temperature shall be measured in the catalyst bed at the 
location where the highest temperature occurs in the hottest catalyst. 
Alternatively, the feed gas temperature may be measured and converted to 
catalyst bed temperature using a linear transform calculated from 
correlation data collected on the catalyst design and aging bench to be 
used in the aging process.
    2. Control the catalyst temperature at stoichiometric operation (01 
to 40 seconds on the cycle) to a minimum of 800 [deg]C (10 [deg]C) by selecting the appropriate Engine speed, 
load, and spark timing for the engine. Control the maximum catalyst 
temperature that occurs during the cycle to 890 [deg]C (10 [deg]C) by selecting the appropriate A/F ratio of the 
engine during the ``rich'' phase described in the table below.
    3. If a low control temperature other than 800 [deg]C is utilized, 
the high control temperature shall be 90 [deg]C higher than the low 
control temperature.

   Sec. Appendix VIII to Part 86--Aging Bench Equipment and Procedures

    This appendix provides specifications for standard aging bench 
equipment and aging procedures which may be used to conduct bench aging 
durability under the provisions of Sec.86.1823-08.

                      1. Aging Bench Configuration

    The aging bench must provide the appropriate exhaust flow rate, 
temperature, air-fuel ratio, exhaust constituents and secondary air 
injection at the inlet face of the catalyst.
    a. The EPA standard aging bench consists of an engine, engine 
controller, and engine dynamometer. Other configurations may be 
acceptable (e.g. whole vehicle on a dynamometer, or a burner that 
provides the correct exhaust conditions), as long as the catalyst inlet 
conditions and control features specified in this appendix are met.
    b. A single aging bench may have the exhaust flow split into several 
streams providing that each exhaust stream meets the requirements of 
this appendix. If the bench has more than one exhaust stream, multiple 
catalyst systems may be aged simultaneously.

                             2. Fuel and Oil

    The fuel used by the engine shall comply with the mileage 
accumulation fuel provisions of Sec.86.113 for the applicable fuel 
type (e.g., gasoline or diesel fuel). The oil used in the engine shall 
be representative of commercial oils and selected using good engineering 
judgement.

                     3. Exhaust System Installation

    a. The entire catalyst(s)-plus-oxygen-sensor(s) system, together 
with all exhaust piping which connects these components, [the ``catalyst 
system''] will be installed on the bench. For engines with multiple 
exhaust streams (such as some V6 and V8 engines), each bank of the 
exhaust system will be installed separately on the bench.
    b. For exhaust systems that contain multiple in-line catalysts, the 
entire catalyst system including all catalysts, all oxygen sensors and 
the associated exhaust piping will be installed as a unit for aging. 
Alternatively, each individual catalyst may be separately aged for the 
appropriate period of time.

                       4. Temperature Measurement

    Catalyst temperature shall be measured using a thermocouple placed 
in the catalyst

[[Page 1204]]

bed at the location where the highest temperature occurs in the hottest 
catalyst (typically this occurs approximately one-inch behind the front 
face of the first catalyst at its longitudinal axis). Alternatively, the 
feed gas temperature just before the catalyst inlet face may be measured 
and converted to catalyst bed temperature using a linear transform 
calculated from correlation data collected on the catalyst design and 
aging bench to be used in the aging process. The catalyst temperature 
must be stored digitally at the speed of 1 hertz (one measurement per 
second).

                         5. Air/Fuel Measurement

    Provisions must be made for the measurement of the air/fuel (A/F) 
ratio (such as a wide-range oxygen sensor) as close as possible to the 
catalyst inlet and outlet flanges. The information from these sensors 
must be stored digitally at the speed of 1 hertz (one measurement per 
second).

                         6. Exhaust Flow Balance

    Provisions must be made to assure that the proper amount of exhaust 
(measured in grams/second at stoichiometry, with a tolerance of 5 grams/second) flows through each catalyst system that 
is being aged on the bench. The proper flow rate is determined based 
upon the exhaust flow that would occur in the original vehicle's engine 
at the steady state engine speed and load selected for the bench aging 
in paragraph (7).

                                7. Setup

    a. The engine speed, load, and spark timing are selected to achieve 
a catalyst bed temperature of 800 [deg]C (10 
[deg]C) at steady-state stoichiometric operation.
    b. The air injection system is set to provide the necessary air flow 
to produce 3.0% oxygen (0.1%) in the steady-state 
stoichiometric exhaust stream just in front of the first catalyst. A 
typical reading at the upstream A/F measurement point (required in 
paragraph 5) is lambda 1.16 (which is approximately 3% oxygen).
    c. With the air injection on, set the ``Rich'' A/F ratio to produce 
a catalyst bed temperature of 890 [deg]C (10 
[deg]C). A typical A/F value for this step is lambda 0.94 (approximately 
2% CO).

                             8. Aging Cycle

    The standard bench aging procedures use the standard bench cycle 
(SBC) which is described in appendix VII to part 86. The SBC is repeated 
until the amount of aging calculated from the bench aging time (BAT) 
equation [ref. Sec.86.1823-08 (d)(3)] is achieved.

                          9. Quality Assurance

    a. The temperatures and A/F ratio information that is required to be 
measured in paragraphs (4) and (5) shall be reviewed periodically (at 
least every 50 hours) during aging. Necessary adjustments shall be made 
to assure that the SBC is being appropriately followed throughout the 
aging process.
    b. After the aging has been completed, the catalyst time-at-
temperature collected during the aging process shall be tabulated into a 
histogram with temperature bins of no larger than 10 [deg]C. The BAT 
equation and the calculated effective reference temperature for the 
aging cycle [ref. Sec.86.1823-08(d)] will be used to determine if the 
appropriate amount of thermal aging of the catalyst has in fact 
occurred. Bench aging will be extended if the thermal effect of the 
calculated aging time is not at least 95% of the target thermal aging.

                        10. Startup and Shutdown

    Care should be taken to assure that the maximum catalyst temperature 
for rapid deterioration (e.g., 1050 [deg]C) does not occur during 
startup or shutdown. Special low temperature startup and shutdown 
procedures may be used to alleviate this concern.

Sec. Appendix IX to Part 86--Experimentally Determining the R-Factor for 
                    Bench Aging Durability Procedures

    The R-Factor is the catalyst thermal reactivity coefficient used in 
the bench aging time (BAT) equation [Ref. Sec.86.1826-08(d)(3)]. 
Manufacturers may determine the value of R experimentally using the 
following procedures.
    1. Using the applicable bench cycle and aging bench hardware, age 
several catalysts (minimum of 3 of the same catalyst design) at 
different control temperatures between the normal operating temperature 
and the damage limit temperature. Measure emissions (or catalyst 
inefficiency (1-catalyst efficiency)) for each constituent. Assure that 
the final testing yields data between one- and two-times the standard.
    2. Estimate the value of R and calculate the effective reference 
temperature (Tr) for the bench aging cycle for each control 
temperature according to the procedure described in Sec.86.1826-
08(d)(4).
    3. Plot emissions (or catalyst inefficiency) versus aging time for 
each catalyst. Calculate the least-squared best-fit line through the 
data. For the data set to be useful for this purpose the data should 
have an approximately common intercept between 0 and 4000 miles. See the 
following graph for an example.
    4. Calculate the slope of the best-fit line for each aging 
temperature.
    5. Plot the natural log (ln) of the slope of each best-fit line 
(determined in step 4)

along the vertical axis, versus the inverse of aging temperature (1/
(aging temperature, deg K)) along the horizontal axis, Calculate the 
least-squared best-fit lines through the data. The slope of the line is 
the R-factor. See the following graph for an example.

    6. Compare the R-factor to the initial value that was used in Step 
2. If the calculated R-factor differs from the initial value by more 
than 5%, choose a new R-factor that is between the initial and 
calculated values, then repeat Steps 2-6 to derive a new R-factor. 
Repeat this process until the calculated R-factor is within 5% of the 
initially assumed R-factor.
    7. Compare the R-factor determined separately for each constituent. 
Use the lowest R-factor (worst case) for the BAT equation.
