                               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, 2015), 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 accidentally dropped due to a printing or computer 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.

[[Page vii]]

    An index to the text of ``Title 3--The President'' is carried within 
that volume.
    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.

INQUIRIES

    For a legal interpretation or explanation of any regulation in this 
volume, contact the issuing agency. The issuing agency's name appears at 
the top of odd-numbered pages.

Subpart QQQ_National Emission Standards for Hazardous Air Pollutants for 
                         Primary Copper Smelting

    Source: 67 FR 40491, June 12, 2002, unless otherwise noted.

                        What This Subpart Covers



Sec. 63.1440  What is the purpose of this subpart?

    This subpart establishes national emission standards for hazardous 
air pollutants (NESHAP) for primary copper smelters. This subpart also 
establishes requirements to demonstrate initial and continuous 
compliance with all applicable emission limitations, work practice 
standards, and operation and maintenance requirements in this subpart.



Sec. 63.1441  Am I subject to this subpart?

    You are subject to this subpart if you own or operate a primary 
copper smelter that is (or is part of) a major source of hazardous air 
pollutant (HAP) emissions on the first compliance date that applies to 
you, and your primary copper smelter uses batch copper converters as 
defined in Sec. 63.1459. Your primary copper smelter is a major source 
of HAP if it emits or has the potential to emit any single HAP at the 
rate of 10 tons or more per year or any combination of HAP at a rate of 
25 tons or more per year.



Sec. 63.1442  What parts of my plant does this subpart cover?

    (a) This subpart applies to each new and existing affected source at 
your primary copper smelter. The affected sources are each copper 
concentrate dryer, each smelting furnace, each slag cleaning vessel, 
each copper converter department, and the entire group of fugitive 
emission sources, as defined in Sec. 63.1459.
    (b) An affected source at your primary copper smelter is existing if 
you commenced construction or reconstruction of the affected source 
before April 20, 1998.
    (c) An affected source at your primary copper smelter is new if you 
commenced construction or reconstruction of the affected source on or 
after April 20, 1998. An affected source is reconstructed if it meets 
the definition of ``reconstruction'' in Sec. 63.2.



Sec. 63.1443  When do I have to comply with this subpart?

    (a) If you have an existing affected source, you must comply with 
each emission limitation, work practice standard, and operation and 
maintenance requirement in this subpart that applies to you no later 
than June 13, 2005.
    (b) If you have a new affected source and its initial startup date 
is on or before June 12, 2002, you must comply with each emission 
limitation, work practice standard, and operation and maintenance 
requirement in this subpart that applies to you by June 12, 2002.
    (c) If you have a new affected source and its initial startup date 
is after

[[Page 28]]

June 12, 2002, you must comply with each emission limitation, work 
practice standard, and operation and maintenance requirement in this 
subpart that applies to you upon initial startup.
    (d) If your primary copper smelter is an area source that becomes a 
major source of HAP, the compliance dates listed in paragraphs (d)(1) 
and (2) of this section apply to you.
    (1) Any portion of the existing primary copper smelter that is a new 
affected source or a new reconstructed source must be in compliance with 
this subpart upon startup.
    (2) All other parts of the primary copper smelter must be in 
compliance with this subpart no later than 3 years after it becomes a 
major source.
    (e) You must meet the notification and schedule requirements in 
Sec. 63.1454. Several of these notifications must be submitted before 
the compliance date for your affected source.

            Emission Limitations and Work Practice Standards



Sec. 63.1444  What emissions limitations and work practice standards
must I meet for my copper concentrate dryers, smelting furnaces,
slag cleaning vessels,  and copper converter departments?

    (a) Copper concentrate dryers. For each copper concentrate dryer, 
you must comply with the emission limitation in paragraph (a)(1) or (2) 
of this section that applies to you.
    (1) For each existing copper concentrate dryer, you must not cause 
to be discharged to the atmosphere from the dryer vent any gases that 
contain total particulate matter in excess of 50 milligrams per dry 
standard cubic meter (mg/dscm) as measured using the test methods 
specified in Sec. 63.1450(a).
    (2) For each new copper concentrate dryer, you must not cause to be 
discharged to the atmosphere from the dryer vent any gases that contain 
total particulate matter in excess of 23 mg/dscm as measured using the 
test methods specified in Sec. 63.1450(a).
    (b) Smelting furnaces. For each smelting furnace, you must comply 
with the emission limitations and work practice standards in paragraphs 
(b)(1) and (2) of this section.
    (1) For each smelting furnace, you must not cause to be discharged 
to the atmosphere any process off-gas that contains nonsulfuric acid 
particulate matter in excess of 6.2 mg/dscm as measured using the test 
methods specified in Sec. 63.1450(b). Process off-gas from a smelting 
furnace is generated when copper ore concentrates and fluxes are being 
smelted to form molten copper matte and slag layers.
    (2) For each smelting furnace, you must control the process fugitive 
emissions released when tapping copper matte or slag from the smelting 
furnace according to paragraphs (b)(2)(i) and (ii) of this section.
    (i) At all times when copper matte or slag is tapped from the 
smelting furnace, you must operate a capture system that collects the 
gases and fumes released from the tapping port in use. The design and 
placement of this capture system must be such that the tapping port 
opening, launder, and receiving vessel (e.g., ladle, slag pot) are 
positioned within the confines or influence of the capture system's 
ventilation draft during those times when the copper matte or slag is 
flowing from the tapping port opening.
    (ii) You must not cause to be discharged to the atmosphere from the 
capture system used to comply with paragraph (b)(2)(i) of this section 
any gases that contain total particulate matter in excess of 23 mg/dscm 
as measured using the test methods specified in Sec. 63.1450(a).
    (c) Slag cleaning vessels. For each slag cleaning vessel, you must 
comply with the emission limitations and work practice standards in 
paragraphs (c)(1) through (3) of this section that apply to you.
    (1) For each slag cleaning vessel, except as provided for in 
paragraph (c)(2) of this section, you must not cause to be discharged to 
the atmosphere any process off-gas that contains nonsulfuric acid 
particulate matter in excess of 6.2 mg/dscm as measured using the test 
methods specified in Sec. 63.1450(b).
    (2) As an alternative to complying with the emission limit for 
nonsulfuric acid particulate matter in paragraph (c)(1) of this section, 
for each existing slag cleaning vessel you may choose to comply with the 
emission limit for

[[Page 29]]

total particulate matter specified in this paragraph (c)(2). You must

    (3) For each slag cleaning vessel, you must control process fugitive 
emissions released when tapping copper matte or slag from the slag 
cleaning vessel according to paragraphs (c)(3)(i) and (ii) of this 
section.
    (i) At all times when copper matte or slag is tapped from the slag 
cleaning vessel, you must operate a capture system that collects the 
gases and fumes released from the tapping port in use. The design and 
placement of this capture system must be such that the tapping port 
opening, launder, and receiving vessel (e.g., ladle, slag pot) are 
positioned within the confines or influence of the capture system's 
ventilation draft during those times when the copper matte or slag is 
flowing from the tapping port opening.
    (ii) You must not cause to be discharged to the atmosphere from the 
capture system used to comply with paragraph (c)(3)(i) of this section 
any gases that contain total particulate matter in excess of 23 mg/dscm

    (d) Existing copper converter departments. For each existing copper 
converter department, you must comply with the emission limitations and 
work practice standards in paragraphs (d)(1) through (6) of this section 
that apply to you.
    (1) You must operate a capture system that collects the process off 
gas vented from each batch copper converter. At all times when one or 
more batch copper converters are blowing, you must operate the capture 
system according to the written operation and maintenance plan that has 
been prepared according to the requirements in Sec. 63.1447(b).
    (2) If your copper converter department uses Pierce-Smith 
converters, the capture system design must include use of a primary hood 
that covers the entire mouth of the converter vessel when the copper 
converter is positioned for blowing. Additional hoods (e.g., secondary 
hoods) or other capture devices must be included in the capture system 
design as needed to achieve the opacity limit in paragraph (d)(4) of 
this section. The capture system design may use multiple intake and duct 
segments through which the ventilation rates are controlled 
independently of each other, and individual duct segments may be 
connected to separate control devices.
    (3) If your copper converter department uses Hoboken converters, the 
capture system must collect all process off-gas vented during blowing 
through the side-flue intake on each converter vessel.
    (4) You must operate the capture system such that any visible 
emissions exiting the roof monitors or roof exhaust fans on the building 
housing the copper converter department meet the opacity limit as 
specified in paragraphs (d)(4)(i) and (ii) of this section.
    (i) The opacity of any visible emissions exiting the roof monitors 
or roof exhaust fans on the building housing the copper converter 
department must not exceed 4 percent as determined by a performance test 
conducted according to Sec. 63.1450(c).
    (ii) The opacity limit in paragraph (d)(4)(i) of this section 
applies only at those times when a performance test is conducted 
according to Sec. 63.1450(c). The requirements for compliance with 
opacity and visible emission standards specified in Sec. 63.6(h) do not 
apply to this opacity limit.
    (5) You must not cause to be discharged to the atmosphere from any 
Pierce-Smith converter primary hood capture system or Hoboken converter 
side-flue intake capture system any process off-gas that contains 
nonsulfuric acid particulate matter in excess of 6.2 mg/dscm as measured 
using the test methods specified in Sec. 63.1450(b).
    (6) You must not cause to be discharged to the atmosphere from any 
secondary capture system any gases that contain total particulate matter 
in excess of 23 mg/dscm as measured using the test methods specified in 
Sec. 63.1450(a).
    (e) New copper converter departments. For each new copper converter 
department for which construction commenced on or after April 20, 1998, 
the

[[Page 30]]

use of batch copper converters is prohibited.
    (f) Baghouses. For each baghouse applied to meet any total 
particulate matter emission limit in paragraphs (a) through (d) of this 
section, you must operate the baghouse such that the bag leak detection 
system does not alarm for more than 5 percent of the total operating 
time in any semiannual reporting period.
    (g) Venturi wet scrubbers. For each venturi wet scrubber applied to 
meet any total particulate matter emission limit in paragraphs (a) 
through (d) of this section, you must maintain the hourly average 
pressure drop and scrubber water flow rate at or above the minimum 
levels established during the initial or subsequent performance test.
    (h) Other control devices. For each control device other than a 
baghouse or venturi wet scrubber applied to meet any total particulate 
matter emission limit in paragraphs (a) through (d) of this section, you 
must operate the control device as specified in paragraphs (h)(1) and 
(2) of this section.
    (1) You must select one or more operating parameters, as appropriate 
for the control device design, that can be used as representative and 
reliable indicators of the control device operation.
    (2) You must maintain the hourly average value for each of the 
selected parameters at or above the minimum level or at or below the 
maximum level, as appropriate for the selected parameter, established 
during the initial or subsequent performance test.



Sec. 63.1445  What work practice standards must I meet for my fugitive
dust sources?

    (a) You must control particulate matter emissions from fugitive dust 
sources at your primary copper smelter by operating according to a 
written fugitive dust control plan that has been approved by the 
designated authority. For the purpose of complying with this paragraph 
(a) you may use an existing fugitive dust control plan provided that the 
plan complies with the requirements of this section. A fugitive dust 
control plan is considered to be approved if the plan has been 
incorporated in your applicable State implementation plan, and the 
document addresses the fugitive dust sources specified in paragraph (b) 
of this section and includes the information specified in paragraph (c) 
of this section.
    (b) Your fugitive dust control plan must address each of the 
fugitive dust emission sources listed in paragraphs (b)(1) through (6) 
of this section that are located at your primary copper smelter.
    (1) On-site roadways used by trucks or other motor vehicles (e.g., 
front-end loaders) when transporting bulk quantities of fugitive dust 
materials. Paved roads and parking areas that are not used by these 
vehicles do not need to be included in the plan (e.g., employee and 
visitor parking lots).
    (2) Unloading of fugitive dust materials from trucks or railcars.
    (3) Outdoor piles used for storage of fugitive dust materials.
    (4) Bedding areas used for blending copper concentrate and other 
feed constituents.
    (5) Each transfer point in conveying systems used to transport 
fugitive dust materials. These points include, but are not limited to, 
transfer of material from one conveyor belt to another and transfer of 
material to a hopper or bin.
    (6) Other site-specific sources of fugitive dust emissions that the 
Administrator or delegated permitting authority designate to be included 
in your fugitive dust control plan.
    (c) Your fugitive dust control plan must describe the control 
measures you use to control fugitive dust emissions from each source 
addressed in the plan, as applicable and appropriate for your site 
conditions. Examples of control measures include, but are not limited 
to, locating the source inside a building or other enclosure, installing 
and operating a local hood capture system over the source and venting 
the captured gas stream to a control device, placing material stockpiles 
below grade, installing wind screens or wind fences around the source, 
spraying water on the source as weather conditions require, applying 
appropriate dust suppression agents on the source, or combinations of 
these control measures.

[[Page 31]]

    (d) The requirement for you to operate according to a written 
fugitive dust control plan must be incorporated in your operating permit 
that is issued by the designated permitting authority under part 70 of 
this chapter. A copy of your fugitive dust control plan must be sent to 
the designated permitting authority on or before the compliance date for 
your primary copper smelter, as specified in Sec. 63.1443.



Sec. 63.1446  What alternative emission limitation may I meet for my
combined gas streams?

    (a) For situations where you combine gas streams from two or more 
affected sources for discharge to the atmosphere through a single vent, 
you may choose to meet the requirements in paragraph (b) of this section 
as an alternative to complying with the individual total particulate 
matter emission limits specified in Sec. 63.1444 that apply to you. 
This alternative emission limit for a combined gas stream may be used 
for any combination of the affected source gas steams specified in 
paragraphs (a)(1) through (5) of this section.

                 Operation and Maintenance Requirements



Sec. 63.1447  What are my operation and maintenance requirements?

    (a) As required by Sec. 63.6(e)(1)(i), you must always operate and 
maintain your affected source, including air pollution control and 
monitoring equipment, in a manner consistent with good air pollution 
control practices for minimizing emissions at least to the levels 
required by this subpart.
    (b) You must prepare and operate at all times according to a written 
operation and maintenance plan for each capture system and control 
device subject to standards in Sec. 63.1444 or Sec. 63.1446. The plan 
must address the requirements in paragraphs (b)(1) through (3) of this 
section as applicable to the capture system or control device.
    (1) Preventative maintenance. You must perform preventative 
maintenance for each capture system and control device according to 
written procedures specified in your operation and maintenance plan. The 
procedures must include a preventative maintenance schedule that is 
consistent with the manufacturer's instructions for routine and long-
term maintenance.
    (2) Capture system inspections. You must conduct monthly inspections 
of the equipment components of the capture system that can affect the 
performance of the system to collect the gases and fumes emitted from 
the affected source (e.g., hoods, exposed ductwork, dampers, fans) 
according to written procedures specified in your operation and 
maintenance plan. The inspection procedure must include the requirements 
in paragraphs (b)(2)(i) through (iii) of this section as applicable to 
the capture system or control device.
    (i) Observations of the physical appearance of the equipment to 
confirm the physical integrity of the equipment (e.g., verify by visual 
inspection no holes in ductwork or hoods, no flow constrictions caused 
by dents, or accumulated dust in ductwork).
    (ii) Inspection, and if necessary testing, of equipment components 
to confirm that the component is operating as intended (e.g., verify by 
appropriate measures that flow or pressure sensors,

[[Page 33]]

damper plates, automated damper switches and motors are operating 
according to manufacture or engineering design specifications).
    (iii) In the event that a defective or damaged component is detected 
during an inspection, you must initiate corrective action according to 
written procedures specified in your operation and maintenance plan to 
correct the defect or deficiency as soon as practicable.
    (3) Copper converter department capture system operating limits. You 
must establish, according to the requirements in paragraph (b)(3)(i) 
through (iii) of this section, operating limits for the capture system 
that are representative and reliable indicators of the performance of 
capture system when it is used to collect the process off-gas vented 
from batch copper converters during blowing.
    (i) Select operating limit parameters appropriate for the capture 
system design that are representative and reliable indicators of the 
performance of the capture system when it is used to collect the process 
off-gas vented from batch copper converters during blowing. At a 
minimum, you must use appropriate operating limit parameters that 
indicate the level of the ventilation draft and the damper position 
settings for the capture system when operating to collect the process 
off-gas from the batch copper converters during blowing. Appropriate 
operating limit parameters for ventilation draft include, but are not 
limited to, volumetric flow rate through each separately ducted hood, 
total volumetric flow rate at the inlet to control device to which the 
capture system is vented, fan motor amperage, or static pressure. Any 
parameter for damper position setting may be used that indicates the 
duct damper position relative to the fully open setting.
    (ii) For each operating limit parameter selected in paragraph 
(b)(3)(i) of this section, designate the value or setting for the 
parameter at which the capture system operates during batch copper 
converter blowing. If your blister copper production operations allow 
for more than one batch copper converter to be operating simultaneously 
in the blowing mode, designate the value or setting for the parameter at 
which the capture system operates during each possible batch copper 
converter blowing configuration that you may operate at your smelter 
(i.e., the operating limits with one converter blowing, with two 
converters blowing, with three converters blowing, as applicable to your 
smelter).
    (iii) Include documentation in the plan to support your selection of 
the operating limits established for the capture system. This 
documentation must include a description of the capture system design, a 
description of the capture system operation during blister copper 
production, a description of each selected operating limit parameter, a 
rationale for why you chose the parameter, a description of the method 
used to monitor the parameter according to the requirements in Sec. 
63.1452(a), and the data used to set the value or setting for the 
parameter for each of your batch copper converter configurations.
    (4) Baghouse leak detection corrective actions. In the event a bag 
leak detection system alarm is triggered, you must initiate corrective 
action according to written procedures specified in your operation and 
maintenance plan to determine the cause of the alarm within 1 hour of 
the alarm, initiate corrective action to correct the cause of the 
problem within 24 hours of the alarm, and complete the corrective action 
as soon as practicable. Corrective actions may include, but are not 
limited to, the activities listed in paragraphs (b)(3)(i) through (vi) 
of this section.
    (i) Inspecting the baghouse for air leaks, torn or broken bags or 
filter media, or any other condition that may cause an increase in 
emissions.
    (ii) Sealing off defective bags or filter media.
    (iii) Replacing defective bags or filter media or otherwise 
repairing the control device.
    (iv) Sealing off a defective baghouse compartment.
    (v) Cleaning the bag leak detection system probe, or otherwise 
repair the bag leak detection system.
    (vi) Shutting down the process producing the particulate emissions.

                     Initial Compliance Requirements



Sec. 63.1449  By what dates must I conduct performance tests or other
initial compliance demonstrations?

    (a) As required in Sec. 63.7(a)(2), you must conduct a performance 
test within 180 calendar days of the compliance date that is specified 
in Sec. 63.1443 for your affected source to demonstrate initial 
compliance with each emission and opacity limit in Sec. 63.1443 and 
Sec. 63.1446 that applies to you.
    (b) For each work practice standard and operation and maintenance 
requirement that applies to you where initial compliance is not 
demonstrated using a performance test or opacity observation, you must 
demonstrate initial compliance within 30 calendar days after the 
compliance date that is specified for your affected source in Sec. 
63.1443.



Sec. 63.1450  What test methods and other procedures must I use to 
demonstrate initial compliance with the emission limitations?

    (a) Total particulate matter emission limits. You must conduct each

testing a positive pressure baghouse, but you must use the sample 
traverse location and number of sampling points described in Method 5D.
    (2) As an alternative to using the applicable method specified in 
paragraph (a)(1)(v) of this section, you may determine total particulate 
matter emissions from the control device using Method 29 in appendix A 
of part 60 of this chapter provided that you follow the procedures and 
precautions prescribed in Method 29. If the control device is a positive 
pressure baghouse, you must also follow the measurement procedure

scrubber water flow rate for each individual test run. Your operating 
limits are the lowest average pressure drop and scrubber water flow rate 
value in any of the three runs that meet the applicable emission limit.
    (5) For a control device other than a baghouse or venturi wet 
scrubber applied to emissions from an affected source and subject to 
site-specific operating limit(s) in Sec. 63.1444(h) or Sec. 63.1446(e) 
for appropriate, site-specific operating parameters that are

three runs that meet the applicable emission limit.
    (iv) You must prepare written documentation to support your 
selection of the operating parameters used for the control device. This 
documentation must include a description of each selected parameter, a 
rationale for why you chose the parameter, a description of the method 
used to monitor the parameter, and the data recorded during the 
performance test and used to set the operating limit(s).
    (b) Nonsulfuric acid particulate matter emission limits. You must

capture system operating conditions specified in the approved test plan.
    (2) You must notify the Administrator or delegated authority before 
conducting the opacity observations to allow the Administrator or 
delegated authority the opportunity to have authorized representatives 
attend the test. Written notification of the location and scheduled date 
for conducting the opacity observations must be received by the 
Administrator on or before 30 calendar days before this scheduled date.
    (3) You must gather the data needed for determining compliance with 
the opacity limit using qualified visible emission observers and process 
monitors as described in paragraphs (c)(3)(i) and (ii) of this section.
    (i) Opacity observations must be performed by a sufficient number of 
qualified visible emission observers to obtain two complete concurrent 
sets of opacity readings for the required observation period. Each 
visible emission observer must be certified as a qualified observer by 
the procedure specified in section 3 of Method 9 in appendix A of part 
60 of this chapter. The entire set of readings during the required 
observation period does not need to be made by the same two observers. 
More than two observers may be used to allow for substitutions and 
provide for observer rest breaks. The owner or operator must obtain 
proof of current visible emission reading certification for each 
observer.
    (ii) A person (or persons) familiar with the copper production 
operations conducted at the smelter must serve as the indoor process 
monitor. The indoor process monitor is stationed at a location inside 
the building housing the batch copper converters such that he or she can 
visually observe and record operations that occur in the batch copper 
converter aisle during the times that the visible emission observers are 
making opacity readings. More than one indoor process monitor may be 
used to allow for substitutions and provide for rest breaks.
    (4) You must make all opacity observations using Method 9 in 
appendix A to part 60 of this chapter and following the procedures 
described in paragraphs (c)(4)(i) and (ii) of this section.
    (i) Each visible emission observer must make his or her readings at 
a position from the outside of the building that houses the copper 
converter department such that the observer's line-of-sight is 
approximately perpendicular to the longer axis of the converter 
building, and the observer has an unobstructed view of the building roof 
monitor sections or roof exhaust fan outlets that are positioned over 
each of the batch copper converters inside the building. Opacity 
readings can only be made during those times when the observer's 
position meets the sun orientation and other conditions specified in 
section 2.1 of Method 9.
    (ii) At 15-second intervals, each visible emission observer views 
the building roof monitor sections or roof exhaust fan outlets that are 
positioned over each of the batch copper converters inside the building 
and reads

[[Page 37]]

the opacity of the visible plumes. If no plume is visible, the observer 
records zero as the opacity value for the 15-second interval. In 
situations when it is possible for an observer to distinguish two or 
more visible emission plumes from the building roof monitor sections or 
roof exhaust fan outlets, the observer must identify, to the extent 
feasible, the plume having the highest opacity and record his or her 
opacity reading for that plume as the opacity value for the 15-second 
interval.
    (5) You must make opacity observations for a period of sufficient 
duration to obtain a minimum of 120 1-minute intervals during which at 
least one copper converter is blowing and no interferences have occurred 
from other copper production events, as specified in paragraph (c)(7) of 
this section, which generate visible emissions inside the building that 
potentially can interfere with the visible emissions from the converter 
capture systems as seen by the outside observers. To obtain the required 
number of 1-minute intervals, the observation period may be divided into 
two or more segments performed on the same day or on different days if 
conditions prevent the required number of opacity readings from being 
obtained during one continuous time period. Examples of these conditions 
include, but are not limited to, changes in the sun's orientation 
relative to visible emission observers' positions such that the Method 9 
conditions are no longer met or an unexpected thunder storm. If the 
total observation period is divided into two or more segments, all 
opacity observations must be made during the same set of copper 
production conditions described in your approved test plan as required 
by paragraph (c)(1) of this section.
    (6) You must gather indoor process information during all times that 
the visible emission observers are making opacity readings outside the 
building housing the copper converter department. The indoor process 
monitor must continually observe the operations occurring in the copper 
converter department and prepare a written record of his or her 
observations using the procedure specified in paragraphs (c)(6)(i) 
through (iv) of this section.
    (i) At the beginning of each observation period or segment, the 
clock time setting on the watch or clock to be used by the indoor 
process monitor must be synchronized with the clock time settings for 
the timepieces to be used by the outdoor opacity observers.
    (ii) During each period or segment when opacity readings are being 
made by the visible emission observers, the indoor process monitor must 
continuously observe the operations occurring in the copper converter 
department and record his or her observations in a log book, on data 
sheets, or other type of permanent written format.
    (iii) When a batch copper converter is blowing, a record must be 
prepared for the converter that includes, but is not limited to, the 
clock times for when blowing begins and when blowing ends and the 
converter blowing rate. This information may be recorded by the indoor 
process monitor or by a separate, automated computer data system.
    (iv) The process monitor must record each event other than converter 
blowing that occurs in or nearby the converter aisle that he or she 
observes to generate visible emissions inside the building. The recorded 
entry for each event must include, but is not limited to, a description 
of the event and the clock times when the event begins and when the 
event ends.
    (7) You must prepare a summary of the data for the entire 
observation period using the information recorded during the observation 
period by the outdoor visible emission observers and the indoor process 
monitor and the procedure specified in paragraphs (c)(7)(i) through (iv) 
of this section.
    (i) Using the field data sheets, identify the 1-minute clock times 
for which a total of eight opacity readings were made and recorded by 
both observers at 15-second intervals according to the test procedures 
(i.e., a total of four opacity values have been recorded for the 1-
minute interval by each of the two observers). Calculate the average of 
the eight 15-second interval readings recorded on the field data sheets 
by the two observers during the clock time minute interval (add the four 
consecutive 15-second interval opacity readings made by Observer A 
during the specified clock time minute, plus the four

[[Page 38]]

consecutive 15-second interval opacity readings made by Observer B 
during the same clock time minute, and divide the resulting total by 
eight). Record the clock time and the opacity average for the 1-minute 
interval on a data summary sheet. Figure 1 of this subpart shows an 
example of the format for the data summary sheet you may use, but are 
not required to use.
    (ii) Using the data summary sheets prepared according to paragraph 
(c)(7)(i) of this section and the process information recorded according 
to paragraph (c)(6)(iii) of this section, identify those 1-minute 
intervals for which at least one of the batch copper converters was 
blowing.
    (iii) Using the data summary sheets prepared according to paragraph 
(c)(7)(ii) of this section and the process information recorded 
according to paragraph (c)(6)(iv) of this section, identify the 1-minute 
intervals during which at least one copper converter was blowing but 
none of the interference events listed in paragraphs (c)(7)(iii)(A) 
through (F) of this section occurred. Other ancillary activities not 
listed but conducted in or adjacent to the converter aisle during the 
opacity observations are not considered to be interference events (e.g., 
converter aisle cleaning, placement of smoking ladles or skulls on the 
converter aisle floor).
    (A) Charging of copper matte, reverts, or other materials to a batch 
copper converter;
    (B) Skimming slag or other molten materials from a batch copper 
converter;
    (C) Pouring of blister copper or other molten materials from a batch 
copper converter;
    (D) Return of slag or other molten materials to the flash smelting 
furnace or slag cleaning vessel;
    (E) Roll-out or roll-in of the batch copper converter; or
    (F) Smoke and fumes generated inside the converter building by 
operation of the smelting furnace, the slag cleaning vessel (if used), 
anode refining and casting processes that drift into the copper 
converter department.
    (iv) Using the data summary sheets prepared according to paragraph 
(c)(7)(iii) of this section, up to five 1-minute intervals following an 
interference event may be eliminated from data used for the compliance 
determination calculation specified in paragraph (c)(8) of this section 
by applying a time delay factor. The time delay factor must be a 
constant number of minutes not to exceed 5 minutes that is added to the 
clock time recorded when cessation of the interference event occurs. The 
same time delay factor must be used for all interference events (i.e., a 
constant time delay factor for the smelter of 1 minute, 2 minutes, 3 
minutes, 4 minutes, or 5 minutes). The number of minutes to be used for 
the time delay factor is determined based on the site-specific equipment 
and converter building configuration. An explanation of the rationale 
for selecting the value used for the time delay factor must be prepared 
and included in the test report.
    (8) You must use the data summary prepared in paragraph (c)(7) of 
this section to calculate the average opacity value for a minimum of 120 
1-minute intervals during which at least one copper converter was 
blowing with no interference events as determined according to 
paragraphs (c)(7)(iii) and (iv) of this section. Average opacity is 
calculated using Equation 1 of this section:
[GRAPHIC] [TIFF OMITTED] TR12JN02.026

Where

VEave = Average opacity to be used for compliance 
          determination (percent);
n = Total number of 1-minute intervals during which at least one copper 
          converter was blowing with no interference events as 
          determined according to paragraphs (c)(7)(iii) and (iv) of 
          this section (at least 120 1-minute intervals);
i = 1-minute interval ``i'' during which at least one copper converter 
          was blowing with no interference events as determined 
          according to paragraphs (c)(7)(iii) and (iv) of this section; 
          and
VEi = Average opacity value calculated for the eight opacity 
          readings recorded during 1-minute interval ``i'' (percent).

    (9) You must certify that the copper converter department capture 
system operated during the performance test at the operating limits 
established in your capture system operation and

[[Page 39]]

maintenance plan using the procedure specified in paragraphs (c)(9)(i) 
through (iv) of this section.
    (i) Concurrent with all opacity observations, measure and record 
values for each of the operating limit parameters in your capture system 
operation and maintenance plan according to the monitoring requirements 
specified in Sec. 63.1452(a).
    (ii) For any dampers that are manually set and remain in the same 
position at all times the capture system is operating, the damper 
position must be visually checked and recorded at the beginning and end 
of each opacity observation period segment.
    (iii) Review the recorded monitoring data. Identify and explain any 
times during batch copper converter blowing when the capture system 
operated outside the applicable operating limits.
    (iv) Certify in your performance test report that during all 
observation period segments, the copper converter department capture 
system was operating at the values or settings established in your 
capture system operation and maintenance plan.

type baghouses using self-tensioning (spring-loaded) devices.
    (vii) Confirm the physical integrity of the baghouse through 
quarterly visual inspections of the baghouse interior for air leaks.
    (viii) Inspect fans for wear, material buildup, and corrosion 
through quarterly visual inspections, vibration detectors, or equivalent

electrical connections for continuity, and all mechanical connections 
for leakage.
    (2) For the scrubber water flow rate CPMS, you must meet the 
requirements in paragraphs (c)(2)(i) through (iv) of this section.
    (i) Locate the flow sensor and other necessary equipment in a 
position that provides a representative flow and that

required quality assurance or control activities (including as 
applicable, calibration checks and required zero and span adjustments), 
you must monitor continuously (or collect data at all required 
intervals) at all times an affected source is operating.
    (f) You may not use data recorded during monitoring malfunctions, 
associated repairs, and required quality assurance or control activities 
in data averages and calculations used to report emission or operating 
levels or to fulfill a minimum data availability requirement, if 
applicable. You must use all the data collected during all other periods 
in assessing compliance.
    (g) A monitoring malfunction is any sudden, infrequent, not 
reasonably preventable failure of the monitor to provide valid data. 
Monitoring failures that are caused in part by poor maintenance or 
careless operation are not malfunctions.

Sec. 63.1503  Definitions.

    Terms used in this subpart are defined in the Clean Air Act as 
amended (CAA), in Sec. 63.2, or in this section as follows:
    Add-on air pollution control device means equipment installed on a 
process vent that reduces the quantity of a pollutant that is emitted to 
the air.
    Afterburner means an air pollution control device that uses 
controlled flame combustion to convert combustible materials to 
noncombustible gases; also known as an incinerator or a thermal 
oxidizer.
    Aluminum scrap means fragments of aluminum stock removed during 
manufacturing (i.e., machining), manufactured aluminum articles or parts 
rejected or discarded and useful only as material for reprocessing, and 
waste and discarded material made of aluminum.
    Aluminum scrap shredder means a unit that crushes, grinds, or breaks 
aluminum scrap into a more uniform size prior to processing or charging 
to a scrap dryer/delacquering kiln/decoating kiln, or furnace. A bale 
breaker is not an aluminum scrap shredder.
    Bag leak detection system means an instrument that is capable of 
monitoring particulate matter loadings in the exhaust of a fabric filter 
(i.e., baghouse) in order to detect bag failures. A bag leak detection 
system includes, but is not limited to, an instrument that operates on 
triboelectric, light scattering, light transmittance, or other effect to 
monitor relative particulate matter loadings.
    Chips means small, uniformly-sized, unpainted pieces of aluminum 
scrap, typically below 1\1/4\ inches in any dimension, primarily 
generated by turning, milling, boring, and machining of aluminum parts.
    Clean charge means furnace charge materials, including molten 
aluminum; T-bar; sow; ingot; billet; pig; alloying elements; aluminum 
scrap known by the owner or operator to be entirely free of paints, 
coatings, and lubricants; uncoated/unpainted aluminum chips that have 
been thermally dried or treated by a centrifugal cleaner; aluminum scrap 
dried at 343 [deg]C (650 [deg]F) or higher; aluminum scrap delacquered/
decoated at 482 [deg]C (900 [deg]F) or higher, and runaround scrap.
    Cover flux means salt added to the surface of molten aluminum in a 
group 1 or group 2 furnace, without agitation of the molten aluminum, 
for the purpose of preventing oxidation.
    Customer returns means any aluminum product which is returned by a 
customer to the aluminum company that originally manufactured the 
product prior to resale of the product or further distribution in 
commerce, and which contains no paint or other solid coatings (i.e., 
lacquers).
    D/F means dioxins and furans.

[[Page 54]]

    Dioxins and furans means tetra-, penta-, hexa-, and octachlorinated 
dibenzo dioxins and furans.
    Dross means the slags and skimmings from aluminum melting and 
refining operations consisting of fluxing agent(s), impurities, and/or 
oxidized and non-oxidized aluminum, from scrap aluminum charged into the 
furnace.
    Dross-only furnace means a furnace, typically of rotary barrel 
design, dedicated to the reclamation of aluminum from dross formed 
during melting, holding, fluxing, or alloying operations carried out in 
other process units. Dross and salt flux are the sole feedstocks to this 
type of furnace.
    Emission unit means a group 1 furnace or in-line fluxer at a 
secondary aluminum production facility.
    Fabric filter means an add-on air pollution control device used to 
capture particulate matter by filtering gas streams through filter 
media; also known as a baghouse.
    Feed/charge means, for a furnace or other process unit that operates 
in batch mode, the total weight of material (including molten aluminum, 
T-bar, sow, ingot, etc.) and alloying agents that enter the furnace 
during an operating cycle. For a furnace or other process unit that 
operates continuously, feed/charge means the weight of material 
(including molten aluminum, T-bar, sow, ingot, etc.) and alloying agents 
that enter the process unit within a specified time period (e.g., a time 
period equal to the performance test period). The feed/charge for a 
dross only furnace includes the total weight of dross and solid flux.
    Fluxing means refining of molten aluminum to improve product 
quality, achieve product specifications, or reduce material loss, 
including the addition of solvents to remove impurities (solvent flux); 
and the injection of gases such as chlorine, or chlorine mixtures, to 
remove magnesium (demagging) or hydrogen bubbles (degassing). Fluxing 
may be performed in the furnace or outside the furnace by an in-line 
fluxer.
    Furnace hearth means the combustion zone of a furnace in which the 
molten metal is contained.
    Group 1 furnace means a furnace of any design that melts, holds, or 
processes aluminum that contains paint, lubricants, coatings, or other 
foreign materials with or without reactive fluxing, or processes clean 
charge with reactive fluxing.
    Group 2 furnace means a furnace of any design that melts, holds, or 
processes only clean charge and that performs no fluxing or performs 
fluxing using only nonreactive, non-HAP-containing/non-HAP-generating 
gases or agents.
    HCl means, for the purposes of this subpart, emissions of hydrogen 
chloride that serve as a surrogate measure of the total emissions of the 
HAPs hydrogen chloride, hydrogen fluoride and chlorine.
    In-line fluxer means a device exterior to a furnace, located in a 
transfer line from a furnace, used to refine (flux) molten aluminum; 
also known as a flux box, degassing box, or demagging box.
    Internal scrap means all aluminum scrap regardless of the level of 
contamination which originates from castings or extrusions produced by 
an aluminum die casting facility, aluminum foundry, or aluminum 
extrusion facility, and which remains at all times within the control of 
the company that produced the castings or extrusions.
    Lime means calcium oxide or other alkaline reagent.
    Lime-injection means the continuous addition of lime upstream of a 
fabric filter.
    Melting/holding furnace means a group 1 furnace that processes only 
clean charge, performs melting, holding, and fluxing functions, and does 
not transfer molten aluminum to or from another furnace except for 
purposes of alloy changes, off-specification product drains, or 
maintenance activities.
    Operating cycle means for a batch process, the period beginning when 
the feed material is first charged to the operation and ending when all 
feed material charged to the operation has been processed. For a batch 
melting or holding furnace process, operating cycle means the period 
including the charging and melting of scrap aluminum and the fluxing, 
refining, alloying, and tapping of molten aluminum (the period from tap-
to-tap).

[[Page 55]]

    PM means, for the purposes of this subpart, emissions of particulate 
matter that serve as a measure of total particulate emissions and as a 
surrogate for metal HAPs contained in the particulates, including but 
not limited to, antimony, arsenic, beryllium, cadmium, chromium, cobalt, 
lead, manganese, mercury, nickel, and selenium.
    Pollution prevention means source reduction as defined under the 
Pollution Prevention Act of 1990 (e.g., equipment or technology 
modifications, process or procedure modifications, reformulation or 
redesign of products, substitution of raw materials, and improvements in 
housekeeping, maintenance, training, or inventory control), and other 
practices that reduce or eliminate the creation of pollutants through 
increased efficiency in the use of raw materials, energy, water, or 
other resources, or protection of natural resources by conservation.
    Reactive fluxing means the use of any gas, liquid, or solid flux 
(other than cover flux) that results in a HAP emission. Argon and 
nitrogen are not reactive and do not produce HAP.
    Reconstruction means the replacement of components of an affected 
source or emission unit such that the fixed capital cost of the new 
components exceeds 50 percent of the fixed capital cost that would be 
required to construct a comparable new affected source, and it is 
technologically and economically feasible for the reconstructed source 
to meet relevant standard(s) established in this subpart. Replacement of 
the refractory in a furnace is routine maintenance and is not a 
reconstruction. The repair and replacement of in-line fluxer components 
(e.g., rotors/shafts, burner tubes, refractory, warped steel) is 
considered to be routine maintenance and is not considered a 
reconstruction. In-line fluxers are typically removed to a maintenance/
repair area and are replaced with repaired units. The replacement of an 
existing in-line fluxer with a repaired unit is not considered a 
reconstruction.
    Residence time means, for an afterburner, the duration of time 
required for gases to pass through the afterburner combustion zone. 
Residence time is calculated by dividing the afterburner combustion zone 
volume in cubic feet by the volumetric flow rate of the gas stream in 
actual cubic feet per second.
    Rotary dross cooler means a water-cooled rotary barrel device that 
accelerates cooling of dross.
    Runaround scrap means scrap materials generated on-site by aluminum 
casting, extruding, rolling, scalping, forging, forming/stamping, 
cutting, and trimming operations and that do not contain paint or solid 
coatings. Uncoated/unpainted aluminum chips generated by turning, 
boring, milling, and similar machining operations may be clean charge if 
they have been thermally dried or treated by a centrifugal cleaner, but 
are not considered to be runaround scrap.
    Scrap dryer/delacquering kiln/decoating kiln means a unit used 
primarily to remove various organic contaminants such as oil, paint, 
lacquer, ink, plastic, and/or rubber from aluminum scrap (including used 
beverage containers) prior to melting.
    Secondary aluminum processing unit (SAPU). An existing SAPU means 
all existing group 1 furnaces and all existing in-line fluxers within a 
secondary aluminum production facility. Each existing group 1 furnace or 
existing in-line fluxer is considered an emission unit within a 
secondary aluminum processing unit. A new SAPU means any combination of 
individual group 1 furnaces and in-line fluxers within a secondary 
aluminum processing facility which either were constructed or 
reconstructed after February 11, 1999, or have been permanently 
redesignated as new emission units pursuant to Sec. 63.1505(k)(6). Each 
of the group 1 furnaces or in-line fluxers within a new SAPU is 
considered an emission unit within that secondary aluminum processing 
unit.
    Secondary aluminum production facility means any establishment using 
clean charge, aluminum scrap, or dross from aluminum production, as the 
raw material and performing one or more of the following processes: 
scrap shredding, scrap drying/delacquering/decoating, thermal chip 
drying, furnace operations (i.e., melting, holding, sweating, refining, 
fluxing, or alloying), recovery of aluminum from dross, in-line fluxing, 
or dross cooling. A secondary aluminum production facility

[[Page 56]]

may be independent or part of a primary aluminum production facility. 
For purposes of this subpart, aluminum die casting facilities, aluminum 
foundries, and aluminum extrusion facilities are not considered to be 
secondary aluminum production facilities if the only materials they melt 
are clean charge, customer returns, or internal scrap, and if they do 
not operate sweat furnaces, thermal chip dryers, or scrap dryers/
delacquering kilns/decoating kilns. The determination of whether a 
facility is a secondary aluminum production facility is only for 
purposes of this subpart and any regulatory requirements which are 
derived from the applicability of this subpart, and is separate from any 
determination which may be made under other environmental laws and 
regulations, including whether the same facility is a ``secondary metal 
production facility'' as that term is used in 42 U.S.C. Sec. 7479(1) 
and 40 CFR 52.21(b)(1)(i)(A) (``prevention of significant deterioration 
of air quality'').
    Sidewell means an open well adjacent to the hearth of a furnace with 
connecting arches between the hearth and the open well through which 
molten aluminum is circulated between the hearth, where heat is applied 
by burners, and the open well, which is used for charging scrap and 
solid flux or salt to the furnace, injecting fluxing agents, and 
skimming dross.
    Sweat furnace means a furnace used exclusively to reclaim aluminum 
from scrap that contains substantial quantities of iron by using heat to 
separate the low-melting point aluminum from the scrap while the higher 
melting-point iron remains in solid form.
    TEQ means the international method of expressing toxicity 
equivalents for dioxins and furans as defined in ``Interim Procedures 
for Estimating Risks Associated with Exposures to Mixtures of 
Chlorinated Dibenzo-p-Dioxins and -Dibenzofurans (CDDs and CDFs) and 
1989 Update'' (EPA-625/3-89-016), available from the National Technical 
Information Service (NTIS), 5285 Port Royal Road, Springfield, Virginia 
22161, NTIS no. PB 90-145756.
    THC means, for the purposes of this subpart, total hydrocarbon 
emissions that also serve as a surrogate for the emissions of organic 
HAP compounds.
    Thermal chip dryer means a device that uses heat to evaporate oil or 
oil/water mixtures from unpainted/uncoated aluminum chips. Pre-heating 
boxes or other dryers which are used solely to remove water from 
aluminum scrap are not considered to be thermal chip dryers for purposes 
of this subpart.
    Three-day, 24-hour rolling average means daily calculations of the 
average 24-hour emission rate (lbs/ton of feed/charge), over the 3 most 
recent consecutive 24-hour periods, for a secondary aluminum processing 
unit.
    Total reactive chlorine flux injection rate means the sum of the 
total weight of chlorine in the gaseous or liquid reactive flux and the 
total weight of chlorine in the solid reactive chloride flux, divided by 
the total weight of feed/charge, as determined by the procedure in Sec. 
63.1512(o).

    Note: In-line fluxers using no reactive flux materials cannot be 
included in this calculation since they are not subject to the HCl 
limit.
    (3) The owner or operator must not discharge or allow to be 
discharged to the atmosphere any 3-day, 24-hour rolling average

accordance with the OM&M plan.
    (ii) Operate each fabric filter system such that the bag leak 
detection system alarm does not sound more than 5 percent of the 
operating time during a 6-month block reporting period. In calculating 
this operating time fraction, if inspection of the fabric filter 
demonstrates that no corrective action is required, no alarm time is 
counted. If corrective action is required, each alarm shall be counted 
as a minimum of 1 hour. If the owner or operator takes longer than 1 
hour to initiate corrective action, the alarm time shall

    (m) In-line fluxers using no reactive flux. The owner or operator of 
an in-line fluxer that uses no reactive flux materials must submit a 
certification of compliance with the operational standard for no 
reactive flux materials in Sec. 63.1506(l) for each 6-month reporting 
period. Each certification must contain the information in Sec. 
63.1516(b)(2)(vi).
    (n) Sidewell group 1 furnace with add-on air pollution control 
devices. These requirements apply to the owner or operator of a sidewell 
group 1 furnace using add-on air pollution control devices. The owner or 
operator must:
    (1) Record in an operating log for each charge of a sidewell furnace 
that the level of molten metal was above the top of the passage between 
the sidewell and hearth during reactive flux injection, unless the 
furnace hearth was also equipped with an add-on control device.
    (2) Submit a certification of compliance with the operational 
standards in Sec. 63.1506(m)(7) for each 6-month reporting period. Each 
certification must contain the information in Sec. 63.1516(b)(2)(iii).
    (o) Group 1 furnace without add-on air pollution control devices. 
These requirements apply to the owner or operator of a group 1 furnace 
that is not equipped with an add-on air pollution control device.
    (1) The owner or operator must develop, in consultation with the 
responsible permitting authority, a written site-specific monitoring 
plan. The site-specific monitoring plan must be submitted to the 
permitting authority as part of the OM&M plan. The site-specific 
monitoring plan must contain sufficient procedures to ensure continuing 
compliance with all applicable emission limits and must demonstrate, 
based on documented test results, the relationship between emissions of 
PM, HCl, and D/F and the proposed monitoring parameters for each 
pollutant. Test data must establish the highest level of PM, HCl, and D/
F that will be emitted from the furnace. This may be determined by 
conducting performance

[[Page 70]]

tests and monitoring operating parameters while charging the furnace 
with feed/charge materials containing the highest anticipated levels of 
oils and coatings and fluxing at the highest anticipated rate. If the 
permitting authority determines that any revisions of the site-specific 
monitoring plan are necessary to meet the requirements of this section 
or this subpart, the owner or operator must promptly make all necessary 
revisions and resubmit the revised plan to the permitting authority.
    (i) The owner or operator of an existing affected source must submit 
the site-specific monitoring plan to the applicable permitting authority 
for review at least 6 months prior to the compliance date.
    (ii) The permitting authority will review and approve or disapprove 
a proposed plan, or request changes to a plan, based on whether the plan 
contains sufficient provisions to ensure continuing compliance with 
applicable emission limits and demonstrates, based on documented test 
results, the relationship between emissions of PM, HCl, and D/F and the 
proposed monitoring parameters for each pollutant. Test data must 
establish the highest level of PM, HCl, and D/F that will be emitted 
from the furnace. Subject to permitting agency approval of the OM&M 
plan, this may be determined by conducting performance tests and 
monitoring operating parameters while charging the furnace with feed/
charge materials containing the highest anticipated levels of oils and 
coatings and fluxing at the highest anticipated rate.
    (2) Each site-specific monitoring plan must document each work 
practice, equipment/design practice, pollution prevention practice, or 
other measure used to meet the applicable emission standards.
    (3) Each site-specific monitoring plan must include provisions for 
unit labeling as required in paragraph (c) of this section, feed/charge 
weight measurement (or production weight measurement) as required in 
paragraph (e) of this section and flux weight measurement as required in 
paragraph (j) of this section.
    (4) Each site-specific monitoring plan for a melting/holding furnace 
subject to the clean charge emission standard in Sec. 63.1505(i)(3) 
must include these requirements:
    (i) The owner or operator must record the type of feed/ charge 
(e.g., ingot, thermally dried chips, dried scrap, etc.) for each 
operating cycle or time period used in the performance test; and
    (ii) The owner or operator must submit a certification of compliance 
with the applicable operational standard for clean charge materials in 
Sec. 63.1506(n)(3) for each 6-month reporting period. Each 
certification must contain the information in Sec. 63.1516(b)(2)(iv).
    (5) If a continuous emission monitoring system is included in a 
site-specific monitoring plan, the plan must include provisions for the 
installation, operation, and maintenance of the system to provide 
quality-assured measurements in accordance with all applicable 
requirements of the general provisions in subpart A of this part.
    (6) If a continuous opacity monitoring system is included in a site-
specific monitoring plan, the plan must include provisions for the 
installation, operation, and maintenance of the system to provide 
quality-assured measurements in accordance with all applicable 
requirements of this subpart.
    (7) If a site-specific monitoring plan includes a scrap inspection 
program for monitoring the scrap contaminant level of furnace feed/
charge materials, the plan must include provisions for the demonstration 
and implementation of the program in accordance with all applicable 
requirements in paragraph (p) of this section.
    (8) If a site-specific monitoring plan includes a calculation method 
for monitoring the scrap contaminant level of furnace feed/charge 
materials, the plan must include provisions for the demonstration and 
implementation of the program in accordance with all applicable 
requirements in paragraph (q) of this section.
    (p) Scrap inspection program for group 1 furnace without add-on air 
pollution control devices. A scrap inspection program must include:
    (1) A proven method for collecting representative samples and 
measuring the oil and coatings content of scrap samples;

[[Page 71]]

    (2) A scrap inspector training program;
    (3) An established correlation between visual inspection and 
physical measurement of oil and coatings content of scrap samples;
    (4) Periodic physical measurements of oil and coatings content of 
randomly-selected scrap samples and comparison with visual inspection 
results;
    (5) A system for assuring that only acceptable scrap is charged to 
an affected group 1 furnace; and
    (6) Recordkeeping requirements to document conformance with plan 
requirements.
    (q) Monitoring of scrap contamination level by calculation method 
for group 1 furnace without add-on air pollution control devices. The 
owner or operator of a group 1 furnace dedicated to processing a 
distinct type of furnace feed/charge composed of scrap with a uniform 
composition (such as rejected product from a manufacturing process for 
which the coating-to-scrap ratio can be documented) may include a 
program in the site-specific monitoring plan for determining, 
monitoring, and certifying the scrap contaminant level using a 
calculation method rather than a scrap inspection program. A scrap 
contaminant monitoring program using a calculation method must include:
    (1) Procedures for the characterization and documentation of the 
contaminant level of the scrap prior to the performance test.
    (2) Limitations on the furnace feed/charge to scrap of the same 
composition as that used in the performance test. If the performance 
test was conducted with a mixture of scrap and clean charge, limitations 
on the proportion of scrap in the furnace feed/charge to no greater than 
the proportion used during the performance test.
    (3) Operating, monitoring, recordkeeping, and reporting requirements 
to ensure that no scrap with a contaminant level higher than that used 
in the performance test is charged to the furnace.
    (r) Group 2 furnace. These requirements apply to the owner or 
operator of a new or existing group 2 furnace. The owner or operator 
must:
    (1) Record a description of the materials charged to each furnace, 
including any nonreactive, non-HAP-containing/non-HAP-generating fluxing 
materials or agents.
    (2) Submit a certification of compliance with the applicable 
operational standard for charge materials in Sec. 63.1506(o) for each 
6-month reporting period. Each certification must contain the 
information in Sec. 63.1516(b)(2)(v).
    (s) Site-specific requirements for secondary aluminum processing 
units. (1) An owner or operator of a secondary aluminum processing unit 
at a facility must include, within the OM&M plan prepared in accordance 
with Sec. 63.1510(b), the following information:
    (i) The identification of each emission unit in the secondary 
aluminum processing unit;
    (ii) The specific control technology or pollution prevention measure 
to be used for each emission unit in the secondary aluminum processing 
unit and the date of its installation or application;
    (iii) The emission limit calculated for each secondary aluminum 
processing unit and performance test results with supporting 
calculations demonstrating initial compliance with each applicable 
emission limit;
    (iv) Information and data demonstrating compliance for each emission 
unit with all applicable design, equipment, work practice or operational 
standards of this subpart; and
    (v) The monitoring requirements applicable to each emission unit in 
a secondary aluminum processing unit and the monitoring procedures for 
daily calculation of the 3-day, 24-hour rolling average using the 
procedure in Sec. 63.1510(t).
    (2) The SAPU compliance procedures within the OM&M plan may not 
contain any of the following provisions:
    (i) Any averaging among emissions of differing pollutants;
    (ii) The inclusion of any affected sources other than emission units 
in a secondary aluminum processing unit;
    (iii) The inclusion of any emission unit while it is shutdown; or
    (iv) The inclusion of any periods of startup, shutdown, or 
malfunction in emission calculations.
    (3) To revise the SAPU compliance provisions within the OM&M plan 
prior to the end of the permit term, the

[[Page 72]]

owner or operator must submit a request to the applicable permitting 
authority containing the information required by paragraph (s)(1) of 
this section and obtain approval of the applicable permitting authority 
prior to implementing any revisions.
    (t) Secondary aluminum processing unit. Except as provided in 
paragraph (u) of this section, the owner or operator must calculate and 
record the 3-day, 24-hour rolling average emissions of PM, HCl, and D/F 
for each secondary aluminum processing unit on a daily basis. To 
calculate the 3-day, 24-hour rolling average, the owner or operator 
must:
    (1) Calculate and record the total weight of material charged to 
each emission unit in the secondary aluminum processing unit for each 
24-hour day of operation using the feed/charge weight information 
required in paragraph (e) of this section. If the owner or operator 
chooses to comply on the basis of weight of aluminum produced by the 
emission unit, rather than weight of material charged to the emission 
unit, all performance test emissions results and all calculations must 
be conducted on the aluminum production weight basis.
    (2) Multiply the total feed/charge weight to the emission unit, or 
the weight of aluminum produced by the emission unit, for each emission 
unit for the 24-hour period by the emission rate (in lb/ton of feed/
charge) for that emission unit (as determined during the performance 
test) to provide emissions for each emission unit for the 24-hour 
period, in pounds.
    (3) Divide the total emissions for each SAPU for the 24-hour period 
by the total material charged to the SAPU, or the weight of aluminum 
produced by the SAPU over the 24-hour period to provide the daily 
emission rate for the SAPU.
    (4) Compute the 24-hour daily emission rate using Equation 4:
    [GRAPHIC] [TIFF OMITTED] TR23MR00.003
    
Where,

Eday = The daily PM, HCl, or D/F emission rate for the 
          secondary aluminum processing unit for the 24-hour period;
Ti = The total amount of feed, or aluminum produced, for 
          emission unit i for the 24-hour period (tons or Mg);
ERi = The measured emission rate for emission unit i as 
          determined in the performance test (lb/ton or [micro]g/Mg of 
          feed/charge); and
n = The number of emission units in the secondary aluminum processing 
          unit.

    (5) Calculate and record the 3-day, 24-hour rolling average for each 
pollutant each day by summing the daily emission rates for each 
pollutant over the 3 most recent consecutive days and dividing by 3.
    (u) Secondary aluminum processing unit compliance by individual 
emission unit demonstration. As an alternative to the procedures of 
paragraph (t) of this section, an owner or operator may demonstrate, 
through performance tests, that each individual emission unit within the 
secondary aluminum production unit is in compliance with the applicable 
emission limits for the emission unit.
    (v) Alternative monitoring method for lime addition. The owner or 
operator of a lime-coated fabric filter that employs intermittent or 
noncontinuous lime addition may apply to the Administrator for approval 
of an alternative method for monitoring the lime addition schedule and 
rate based on monitoring the weight of lime added per ton of feed/charge 
for each operating cycle or time period used in the performance test. An 
alternative monitoring method will not be approved unless the owner or 
operator provides assurance through data and information that the 
affected source will meet the relevant emission standards on a 
continuous basis.
    (w) Alternative monitoring methods. If an owner or operator wishes 
to use an alternative monitoring method to demonstrate compliance with 
any emission standard in this subpart, other than those alternative 
monitoring methods which may be authorized pursuant to Sec. 
63.1510(j)(5) and Sec. 63.1510(v), the owner or operator may submit an 
application to the Administrator. Any such application will be processed 
according to the criteria and procedures set forth in paragraphs (w)(1) 
through (6) of this section.

[[Page 73]]

    (1) The Administrator will not approve averaging periods other than 
those specified in this section.
    (2) The owner or operator must continue to use the original 
monitoring requirement until necessary data are submitted and approval 
is received to use another monitoring procedure.
    (3) The owner or operator shall submit the application for approval 
of alternate monitoring methods no later than the notification of the 
performance test. The application must contain the information specified 
in paragraphs (w)(3) (i) through (iii) of this section:
    (i) Data or information justifying the request, such as the 
technical or economic infeasibility, or the impracticality of using the 
required approach;
    (ii) A description of the proposed alternative monitoring 
requirements, including the operating parameters to be monitored, the 
monitoring approach and technique, and how the limit is to be 
calculated; and
    (iii) Data and information documenting that the alternative 
monitoring requirement(s) would provide equivalent or better assurance 
of compliance with the relevant emission standard(s).
    (4) The Administrator will not approve an alternate monitoring 
application unless it would provide equivalent or better assurance of 
compliance with the relevant emission standard(s). Before disapproving 
any alternate monitoring application, the Administrator will provide:
    (i) Notice of the information and findings upon which the intended 
disapproval is based; and
    (ii) Notice of opportunity for the owner or operator to present 
additional supporting information before final action is taken on the 
application. This notice will specify how much additional time is 
allowed for the owner or operator to provide additional supporting 
information.
    (5) The owner or operator is responsible for submitting any 
supporting information in a timely manner to enable the Administrator to 
consider the application prior to the performance test. Neither 
submittal of an application nor the Administrator's failure to approve 
or disapprove the application relieves the owner or operator of the 
responsibility to comply with any provisions of this subpart.
    (6) The Administrator may decide at any time, on a case-by-case 
basis, that additional or alternative operating limits, or alternative 
approaches to establishing operating limits, are necessary to 
demonstrate compliance with the emission standards of this subpart.

Sec. 63.1511  Performance test/compliance demonstration general
requirements.

    (a) Site-specific test plan. Prior to conducting any performance 
test required by this subpart, the owner or operator must prepare a 
site-specific test plan which satisfies all of the requirements, and 
must obtain approval of the plan pursuant to the procedures, set forth 
in Sec. 63.7(c).
    (b) Initial performance test. Following approval of the site-
specific test plan, the owner or operator must demonstrate initial 
compliance with each applicable emission, equipment, work practice, or 
operational standard for each affected source and emission unit, and 
report the results in the notification of compliance status report as 
described in Sec. 63.1515(b). The owner or operator of any existing 
affected source for which an initial performance test is required to 
demonstrate compliance must conduct this initial performance test no 
later than the date for compliance established by Sec. 63.1501(a). The 
owner or operator of any new affected source for which an initial 
performance test is required must conduct this initial performance test 
within 90 days after the date for compliance established by Sec. 
63.1501(b). Except for the date by which the performance test must be 
conducted, the owner or operator must conduct each performance test in 
accordance with the requirements and procedures set forth in Sec. 
63.7(c). Owners or operators of affected sources located at facilities 
which are area sources are subject only to those performance testing 
requirements pertaining to D/F. Owners or operators of

[[Page 74]]

sweat furnaces meeting the specifications of Sec. 63.1505(f)(1) are not 
required to conduct a performance test.
    (1) The owner or operator must conduct each test while the affected 
source or emission unit is operating at the highest production level 
with charge materials representative of the range of materials processed 
by the unit and, if applicable, at the highest reactive fluxing rate.
    (2) Each performance test for a continuous process must consist of 3 
separate runs; pollutant sampling for each run must be conducted for the 
time period specified in the applicable method or, in the absence of a 
specific time period in the test method, for a minimum of 3 hours.
    (3) Each performance test for a batch process must consist of three 
separate runs; pollutant sampling for each run must be conducted over 
the entire process operating cycle.
    (4) Where multiple affected sources or emission units are exhausted 
through a common stack, pollutant sampling for each run must be 
conducted over a period of time during which all affected sources or 
emission units complete at least 1 entire process operating cycle or for 
24 hours, whichever is shorter.
    (5) Initial compliance with an applicable emission limit or standard 
is demonstrated if the average of three runs conducted during the 
performance test is less than or equal to the applicable emission limit 
or standard.
    (c) Test methods. The owner or operator must use the following 
methods in appendix A to 40 CFR part 60 to determine compliance with the 
applicable emission limits or standards:
    (1) Method 1 for sample and velocity traverses.
    (2) Method 2 for velocity and volumetric flow rate.
    (3) Method 3 for gas analysis.
    (4) Method 4 for moisture content of the stack gas.
    (5) Method 5 for the concentration of PM.
    (6) Method 9 for visible emission observations.
    (7) Method 23 for the concentration of D/F.
    (8) Method 25A for the concentration of THC, as propane.
    (9) Method 26A for the concentration of HCl. Where a lime-injected 
fabric filter is used as the control device to comply with the 90 
percent reduction standard, the owner or operator must measure the 
fabric filter inlet concentration of HCl at a point before lime is 
introduced to the system. Method 26 may be used in place of Method 26A 
where it can be demonstrated that there are no water droplets in the 
emission stream. This can be demonstrated by showing that the vapor 
pressure of water in the emission stream that you are testing is less 
than the equilibrium vapor pressure of water at the emission stream 
temperature, and by certifying that the emission stream is not 
controlled by a wet scrubber.
    (d) Alternative methods. The owner or operator may use an 
alternative test method, subject to approval by the Administrator.
    (e) Repeat tests. The owner or operator of new or existing affected 
sources and emission units located at secondary aluminum production 
facilities that are major sources must conduct a performance test every 
5 years following the initial performance test.
    (f) Testing of representative emission units. With the prior 
approval of the permitting authority, an owner or operator may utilize 
emission rates obtained by testing a particular type of group 1 furnace 
which is not controlled by any add-on control device, or by testing an 
in-line flux box which is not controlled by any add-on control device, 
to determine the emission rate for other units of the same type at the 
same facility. Such emission test results may only be considered to be 
representative of other units if all of the following criteria are 
satisfied:
    (1) The tested emission unit must use feed materials and charge 
rates which are comparable to the emission units that it represents;
    (2) The tested emission unit must use the same type of flux 
materials in the same proportions as the emission units it represents;
    (3) The tested emission unit must be operated utilizing the same 
work practices as the emission units that it represents;

[[Page 75]]

    (4) The tested emission unit must be of the same design as the 
emission units that it represents; and
    (5) The tested emission unit must be tested under the highest load 
or capacity reasonably expected to occur for any of the emission units 
that it represents.
    (g) Establishment of monitoring and operating parameter values. The 
owner or operator of new or existing affected sources and emission units 
must establish a minimum or maximum operating parameter value, or an 
operating parameter range for each parameter to be monitored as required 
by Sec. 63.1510 that ensures compliance with the applicable emission 
limit or standard. To establish the minimum or maximum value or range, 
the owner or operator must use the appropriate procedures in this 
section and submit the information required by Sec. 63.1515(b)(4) in 
the notification of compliance status report. The owner or operator may 
use existing data in addition to the results of performance tests to 
establish operating parameter values for compliance monitoring provided 
each of the following conditions are met to the satisfaction of the 
applicable permitting authority:
    (1) The complete emission test report(s) used as the basis of the 
parameter(s) is submitted.
    (2) The same test methods and procedures as required by this subpart 
were used in the test.
    (3) The owner or operator certifies that no design or work practice 
changes have been made to the source, process, or emission control 
equipment since the time of the report.
    (4) All process and control equipment operating parameters required 
to be monitored were monitored as required in this subpart and 
documented in the test report.
    (h) Testing of commonly-ducted units within a secondary aluminum 
processing unit. When group 1 furnaces and/or in-line fluxers are 
included in a single existing SAPU or new SAPU, and the emissions from 
more than one emission unit within that existing SAPU or new SAPU are 
manifolded to a single control device, compliance for all units within 
the SAPU is demonstrated if the total measured emissions from all 
controlled and uncontrolled units in the SAPU do not exceed the emission 
limits calculated for that SAPU based on the applicable equation in 
Sec. 63.1505(k).
    (i) Testing of commonly-ducted units not within a secondary aluminum 
processing unit. With the prior approval of the permitting authority, an 
owner or operator may do combined performance testing of two or more 
individual affected sources or emission units which are not included in 
a single existing SAPU or new SAPU, but whose emissions are manifolded 
to a single control device. Any such performance testing of commonly-
ducted units must satisfy the following basic requirements:
    (1) All testing must be designed to verify that each affected source 
or emission unit individually satisfies all emission requirements 
applicable to that affected source or emission unit;
    (2) All emissions of pollutants subject to a standard must be tested 
at the outlet from each individual affected source or emission unit 
while operating under the highest load or capacity reasonably expected 
to occur, and prior to the point that the emissions are manifolded 
together with emissions from other affected sources or emission units;
    (3) The combined emissions from all affected sources and emission 
units which are manifolded to a single emission control device must be 
tested at the outlet of the emission control device;
    (4) All tests at the outlet of the emission control device must be 
conducted with all affected sources and emission units whose emissions 
are manifolded to the control device operating simultaneously under the 
highest load or capacity reasonably expected to occur; and
    (5) For purposes of demonstrating compliance of a commonly-ducted 
unit with any emission limit for a particular type of pollutant, the 
emissions of that pollutant by the individual unit shall be presumed to 
be controlled by the same percentage as total emissions of that 
pollutant from all commonly-

[[Page 76]]

ducted units are controlled at the outlet of the emission control 
device.

Sec. 63.1512  Performance test/compliance demonstration requirements
and procedures.

    (a) Aluminum scrap shredder. The owner or operator must conduct 
performance tests to measure PM emissions at the outlet of the control 
system. If visible emission observations is the selected monitoring 
option, the owner or operator must record visible emission observations 
from each exhaust stack for all consecutive 6-minute periods during the 
PM emission test according to the requirements of Method 9 in appendix A 
to 40 CFR part 60.

performance test to measure THC and D/F emissions at the outlet of the 
control device while the unit processes only unpainted aluminum chips.
    (c) Scrap dryer/delacquering kiln/decoating kiln. The owner or 
operator must conduct performance tests to measure emissions of THC, D/
F, HCl, and PM at the outlet of the control device.
    (1) If the scrap dryer/delacquering kiln/decoating kiln is subject 
to the alternative emission limits in Sec. 63.1505(e), the average 
afterburner operating temperature in each 3-hour block period must be 
maintained at or above 760 [deg]C (1400 [deg]F) for the test.
    (2) The owner or operator of a scrap dryer/delacquering kiln/
decoating kiln subject to the alternative limits in Sec. 63.1505(e) 
must submit a written certification in the notification of compliance 
status report containing the information required by Sec. 
63.1515(b)(7).
    (d) Group 1 furnace with add-on air pollution control devices. (1) 
The owner or operator of a group 1 furnace that processes scrap other 
than clean charge materials with emissions controlled by a lime-injected 
fabric filter must conduct performance tests to measure emissions of PM 
and D/F at the outlet of the control device and emissions of HCl at the 
outlet (for the emission limit) or the inlet and the outlet (for the 
percent reduction standard).
    (2) The owner or operator of a group 1 furnace that processes only 
clean charge materials with emissions controlled by a lime-injected 
fabric filter must conduct performance tests to measure emissions of PM 
at the outlet of the control device and emissions of HCl at the outlet 
(for the emission limit) or the inlet and the outlet (for the percent 
reduction standard).
    (3) The owner or operator may choose to determine the rate of 
reactive flux addition to the group 1 furnace and assume, for the 
purposes of demonstrating compliance with the SAPU emission limit, that 
all reactive flux added to the group 1 furnace is emitted. Under these 
circumstances, the owner or operator is not required to conduct an 
emission test for HCl.
    (4) The owner or operator of a sidewell group 1 furnace that 
conducts reactive fluxing (except for cover flux) in the hearth, or that 
conducts reactive fluxing in the sidewell at times when the level of 
molten metal falls below the top of the passage between the sidewell and 
the hearth, must conduct the performance tests required by paragraph 
(d)(1) or (d)(2) of this section, to measure emissions from both the 
sidewell and the hearth.
    (e) Group 1 furnace (including melting holding furnaces) without 
add-on air pollution control devices. In the site-specific monitoring 
plan required by Sec. 63.1510(o), the owner or operator of a group 1 
furnace (including a melting/holding furnaces) without add-on air 
pollution control devices must include data and information 
demonstrating compliance with the applicable emission limits.
    (1) If the group 1 furnace processes other than clean charge 
material, the owner or operator must conduct emission tests to measure 
emissions of PM, HCl, and D/F at the furnace exhaust outlet.
    (2) If the group 1 furnace processes only clean charge, the owner or 
operator must conduct emission tests to simultaneously measure emissions 
of PM and HCl at the furnace exhaust outlet. A D/F test is not required. 
Each test must be conducted while the group 1

[[Page 77]]

furnace (including a melting/holding furnace) processes only clean 
charge.
    (3) The owner or operator may choose to determine the rate of 
reactive flux addition to the group 1 furnace and assume, for the 
purposes of demonstrating compliance with the SAPU emission limit, that 
all reactive flux added to the group 1 furnace is emitted. Under these 
circumstances, the owner or operator is not required to conduct an 
emission test for HCl.
    (f) Sweat furnace. Except as provided in Sec. 63.1505(f)(1), the 
owner or operator must measure emissions of D/F from each sweat furnace 
at the outlet of the control device.
    (g) Dross-only furnace. The owner or operator must conduct a 
performance test to measure emissions of PM from each dross-only furnace 
at the outlet of each control device while the unit processes only dross 
and salt flux as the sole feedstock.
    (h) In-line fluxer. (1) The owner or operator of an in-line fluxer 
that uses reactive flux materials must conduct a performance test to 
measure emissions of HCl and PM or otherwise demonstrate compliance in 
accordance with paragraph (h)(2) of this section. If the in-line fluxer 
is equipped with an add-on control device, the emissions must be 
measured at the outlet of the control device.
    (2) The owner or operator may choose to limit the rate at which 
reactive chlorine flux is added to an in-line fluxer and assume, for the 
purposes of demonstrating compliance with the SAPU emission limit, that 
all chlorine in the reactive flux added to the in-line fluxer is emitted 
as HCl. Under these circumstances, the owner or operator is not required 
to conduct an emission test for HCl. If the owner or operator of any in-
line flux box which has no ventilation ductwork manifolded to any outlet 
or emission control device chooses to demonstrate compliance with the 
emission limit for HCl by limiting use of reactive chlorine flux and 
assuming that all chlorine in the flux is emitted as HCl, compliance 
with the HCl limit shall also constitute compliance with the emission 
limit for PM, and no separate emission test for PM is required. In this 
case, the owner or operator of the unvented in-line flux box must 
utilize the maximum permissible PM emission rate for the in-line flux 
boxes when determining the total emissions for any SAPU which includes 
the flux box.
    (i) Rotary dross cooler. The owner or operator must conduct a 
performance test to measure PM emissions at the outlet of the control 
device.
    (j) Secondary aluminum processing unit. The owner or operator must 
conduct performance tests as described in paragraphs (j)(1) through (3) 
of this section. The results of the performance tests are used to 
establish emission rates in lb/ton of feed/charge for PM and HCl and 
[micro]g TEQ/Mg of feed/charge for D/F emissions from each emission 
unit. These emission rates are used for compliance monitoring in the 
calculation of the 3-day, 24-hour rolling average emission rates using 
the equation in Sec. 63.1510(t). A performance test is required for:
    (1) Each group 1 furnace processing only clean charge to measure 
emissions of PM and either:
    (i) Emissions of HCl (for the emission limit); or
    (ii) The mass flow rate of HCl at the inlet to and outlet from the 
control device (for the percent reduction standard).
    (2) Each group 1 furnace that processes scrap other than clean 
charge to measure emissions of PM and D/F and either:
    (i) Emissions of HCl (for the emission limit); or
    (ii) The mass flow rate of HCl at the inlet to and outlet from the 
control device (for the percent reduction standard).
    (3) Each in-line fluxer to measure emissions of PM and HCl.
    (k) Feed/charge weight measurement. During the emission test(s) 
conducted to determine compliance with emission limits in a kg/Mg (lb/
ton) format, the owner or operator of an affected source or emission 
unit, subject to an emission limit in a kg/Mg (lb/ton) of feed/charge 
format, must measure (or otherwise determine) and record the total 
weight of feed/charge to the affected source or emission unit for each 
of the three test runs and calculate and record the total weight. An 
owner or operator that chooses to demonstrate

[[Page 78]]

compliance on the basis of the aluminum production weight must measure 
the weight of aluminum produced by the emission unit or affected source 
instead of the feed/charge weight.
    (l) Continuous opacity monitoring system. The owner or operator of 
an affected source or emission unit using a continuous opacity 
monitoring system must conduct a performance evaluation to demonstrate 
compliance with Performance Specification 1 in appendix B to 40 CFR part 
60. Following the performance evaluation, the owner or operator must 
measure and record the opacity of emissions from each exhaust stack for 
all consecutive 6-minute periods during the PM emission test.
    (m) Afterburner. These requirements apply to the owner or operator 
of an affected source using an afterburner to comply with the 
requirements of this subpart.
    (1) Prior to the initial performance test, the owner or operator 
must conduct a performance evaluation for the temperature monitoring 
device according to the requirements of Sec. 63.8.
    (2) The owner or operator must use these procedures to establish an 
operating parameter value or range for the afterburner operating 
temperature.
    (i) Continuously measure and record the operating temperature of 
each afterburner every 15 minutes during the THC and D/F performance 
tests;
    (ii) Determine and record the 15-minute block average temperatures 
for the three test runs; and
    (iii) Determine and record the 3-hour block average temperature 
measurements for the 3 test runs.
    (n) Inlet gas temperature. The owner or operator of a scrap dryer/
delacquering kiln/decoating kiln or a group 1 furnace using a lime-
injected fabric filter must use these procedures to establish an 
operating parameter value or range for the inlet gas temperature.
    (1) Continuously measure and record the temperature at the inlet to 
the lime-injected fabric filter every 15 minutes during the HCl and D/F 
performance tests;
    (2) Determine and record the 15-minute block average temperatures 
for the 3 test runs; and
    (3) Determine and record the 3-hour block average of the recorded 
temperature measurements for the 3 test runs.
    (o) Flux injection rate. The owner or operator must use these 
procedures to establish an operating parameter value or range for the 
total reactive chlorine flux injection rate.
    (1) Continuously measure and record the weight of gaseous or liquid 
reactive flux injected for each 15 minute period during the HCl and D/F 
tests, determine and record the 15-minute block average weights, and 
calculate and record the total weight of the gaseous or liquid reactive 
flux for the 3 test runs;
    (2) Record the identity, composition, and total weight of each 
addition of solid reactive flux for the 3 test runs;
    (3) Determine the total reactive chlorine flux injection rate by 
adding the recorded measurement of the total weight of chlorine in the 
gaseous or liquid reactive flux injected and the total weight of 
chlorine in the solid reactive flux using Equation 5:

Where,

Wt = Total chlorine usage, by weight;
F1 = Fraction of gaseous or liquid flux that is chlorine;
W1 = Weight of reactive flux gas injected;
F2 = Fraction of solid reactive chloride flux that is 
          chlorine (e.g., F = 0.75 for magnesium chloride; and
W2 = Weight of solid reactive flux;

    (4) Divide the weight of total chlorine usage (Wt) for 
the 3 test runs by the recorded measurement of the total weight of feed 
for the 3 test runs; and
    (5) If a solid reactive flux other than magnesium chloride is used, 
the owner or operator must derive the appropriate proportion factor 
subject to approval by the applicable permitting authority.
    (p) Lime injection. The owner or operator of an affected source or 
emission unit using a lime-injected fabric filter system must use these 
procedures during the HCl and D/F tests to establish an operating 
parameter value for the feeder setting for each operating cycle or time 
period used in the performance test.

[[Page 79]]

    (1) For continuous lime injection systems, ensure that lime in the 
feed hopper or silo is free-flowing at all times; and
    (2) Record the feeder setting for the 3 test runs. If the feed rate 
setting varies during the runs, determine and record the average feed 
rate from the 3 runs.
    (q) Bag leak detection system. The owner or operator of an affected 
source or emission unit using a bag leak detection system must submit 
the information described in Sec. 63.1515(b)(6) as part of the

limits for lead compounds under Sec. 63.1543(a)and (b) must install a 
CEMS for measuring lead emissions within 180 days of promulgation of 
performance specifications for lead CEMS.
    (i) Prior to promulgation of performance specifications for CEMS 
used to measure lead concentrations, an owner or operator must use the 
procedure described in Sec. 63.1546(a)(1) through (7) of this section 
to determine compliance.
    (2) If a CEMS used to measure lead emissions is applicable, the 
owner or operator must install a CERMS with a sensor in a location that 
provides representative measurement of the exhaust gas flow rate at the 
sampling location of the CEMS used to measure lead emissions, taking 
into account the manufacturer's recommendations. The flow rate sensor is 
that portion of the system that senses the volumetric flow rate and 
generates an output proportional to that flow rate.
    (i) The CERMS must be designed to measure the exhaust gas flow rate 
over a range that extends from a value of at least 20 percent less than 
the lowest expected exhaust flow rate to a value of at least 20 percent 
greater than the highest expected exhaust gas flow rate.
    (ii) The CERMS must be equipped with a data acquisition and 
recording system that is capable of recording values over the entire 
range specified in paragraph (j)(2)(i) of this section.
    (iii) Each owner or operator must perform an initial relative 
accuracy test of the CERMS in accordance with the applicable Performance 
Specification in appendix B to part 60 of the chapter.
    (iv) Each owner or operator must operate the CERMS and record data 
during all periods of operation of the affected facility including 
periods of startup, shutdown, and malfunction, except for periods of 
monitoring system malfunctions, repairs associated with monitoring 
system malfunctions, and required monitoring system quality assurance or 
quality control activities (including, as applicable, calibration checks 
and required zero and span adjustments.
    (3) Each owner or operator must calculate the lead emissions rate in 
tons per year by summing all hours of CEMS data for a year to determine 
compliance with Sec. 63.1543(b).
    (i) When the CERMS are unable to provide quality assured data the 
following applies:
    (A) When data are not available for periods of up to 48 hours, the 
highest recorded hourly emission rate from the previous 24 hours must be 
used.
    (B) When data are not available for 48 or more hours, the maximum 
daily emission rate based on the previous 30 days must be used.

Sec. 63.1551  Affirmative defense for exceedance of emission limit
during malfunction.

    In response to an action to enforce the standards set forth in this 
subpart you may assert an affirmative defense to a claim for civil 
penalties for exceedances of such standards that are caused by 
malfunction, as defined at 40 CFR 63.2. Appropriate penalties may be 
assessed, however, if you fail to meet your burden of proving all of the 
requirements in the affirmative defense. The affirmative defense shall 
not be available for claims for injunctive relief.
    (a) Affirmative defense. To establish the affirmative defense in any 
action to enforce such a limit, you must timely meet the notification 
requirements in paragraph (b) of this section, and must prove by a 
preponderance of evidence that:
    (1) The excess emissions:
    (i) Were caused by a sudden, infrequent, and unavoidable failure of 
air pollution control and monitoring equipment, process equipment, or a 
process to operate in a normal or usual manner, and
    (ii) Could not have been prevented through careful planning, proper 
design

[[Page 107]]

or better operation and maintenance practices; and
    (iii) Did not stem from any activity or event that could have been 
foreseen and avoided, or planned for; and
    (iv) Were not part of a recurring pattern indicative of inadequate 
design, operation, or maintenance; and
    (2) Repairs were made as expeditiously as possible when the 
applicable emission limitations were being exceeded. Off-shift and 
overtime labor were used, to the extent practicable to make these 
repairs; and
    (3) The frequency, amount and duration of the excess emissions 
(including any bypass) were minimized to the maximum extent practicable 
during periods of such emissions; and
    (4) If the excess emissions resulted from a bypass of control 
equipment or a process, then the bypass was unavoidable to prevent loss 
of life, personal injury, or severe property damage; and
    (5) All possible steps were taken to minimize the impact of the 
excess emissions on ambient air quality, the environment and human 
health; and
    (6) All emissions monitoring and control systems were kept in 
operation if at all possible, consistent with safety and good air 
pollution control practices; and
    (7) All of the actions in response to the excess emissions were 
documented by properly signed, contemporaneous operating logs; and
    (8) At all times, the facility was operated in a manner consistent 
with good practices for minimizing emissions; and
    (9) A written root cause analysis has been prepared, the purpose of 
which is to determine, correct, and eliminate the primary causes of the 
malfunction and the excess emissions resulting from the malfunction 
event at issue. The analysis shall also specify, using best monitoring 
methods and engineering judgment, the amount of excess emissions that 
were the result of the malfunction.
    (b) Notification. The owner or operator of the facility experiencing 
an exceedance of its emission limit(s) during a malfunction shall notify 
the Administrator by telephone or facsimile (FAX) transmission as soon 
as possible, but no later than two business days after the initial 
occurrence of the malfunction, if it wishes to avail itself of an 
affirmative defense to civil penalties for that malfunction. The owner 
or operator seeking to assert an affirmative defense shall also submit a 
written report to the Administrator within 45 days of the initial 
occurrence of the exceedance of the standards in this subpart to 
demonstrate, with all necessary supporting documentation, that it has 
met the requirements set forth in paragraph (a) of this section. The 
owner or operator may seek an extension of this deadline for up to 30 
additional days by submitting a written request to the Administrator 
before the expiration of the 45 day period. Until a request for an 
extension has been approved by the Administrator, the owner or operator 
is subject to the requirement to submit such report within 45 days of 
the initial occurrence of the exceedance.

Subpart UUU_National Emission Standards for Hazardous Air Pollutants for 
  Petroleum Refineries: Catalytic Cracking Units, Catalytic Reforming 
                    Units, and Sulfur Recovery Units

    Source: 67 FR 17773, Apr. 11, 2002, unless otherwise noted.

                        What This Subpart Covers



Sec. 63.1560  What is the purpose of this subpart?

    This subpart establishes national emission standards for hazardous 
air pollutants (HAP) emitted from petroleum refineries. This subpart 
also establishes requirements to demonstrate initial and continuous 
compliance with the emission limitations and work practice standards.



Sec. 63.1561  Am I subject to this subpart?

    (a) You are subject to this subpart if you own or operate a 
petroleum refinery that is located at a major source of HAP emissions.
    (1) A petroleum refinery is an establishment engaged primarily in 
petroleum refining as defined in the Standard Industrial Classification 
(SIC) code 2911 and the North American Industry Classification (NAIC) 
code 32411, and used mainly for:
    (i) Producing transportation fuels (such as gasoline, diesel fuels, 
and jet fuels), heating fuels (such as kerosene, fuel gas distillate, 
and fuel oils), or lubricants;
    (ii) Separating petroleum; or
    (iii) Separating, cracking, reacting, or reforming an intermediate 
petroleum stream, or recovering a by-product(s) from the intermediate 
petroleum stream (e.g., sulfur recovery).
    (2) A major source of HAP is a plant site that emits or has the 
potential to emit any single HAP at a rate of 9.07 megagrams (10 tons) 
or more per year

[[Page 109]]

or any combination of HAP at a rate of 22.68 megagrams (25 tons) or more 
per year.
    (b) [Reserved]



Sec. 63.1562  What parts of my plant are covered by this subpart?

    (a) This subpart applies to each new, reconstructed, or existing 
affected source at a petroleum refinery.
    (b) The affected sources are:
    (1) The process vent or group of process vents on fluidized 
catalytic cracking units that are associated with regeneration of the 
catalyst used in the unit (i.e., the catalyst regeneration flue gas 
vent).
    (2) The process vent or group of process vents on catalytic 
reforming units (including but not limited to semi-regenerative, cyclic, 
or continuous processes) that are associated with regeneration of the 
catalyst used in the unit. This affected source includes vents that are 
used during the unit depressurization, purging, coke burn, and catalyst 
rejuvenation.
    (3) The process vent or group of process vents on Claus or other 
types of sulfur recovery plant units or the tail gas treatment units 
serving sulfur recovery plants, that are associated with sulfur 
recovery.
    (4) Each bypass line serving a new, existing, or reconstructed 
catalytic cracking unit, catalytic reforming unit, or sulfur recovery 
unit. This means each vent system that contains a bypass line (e.g., 
ductwork) that could divert an affected vent stream away from a control 
device used to comply with the requirements of this subpart.
    (c) An affected source is a new affected source if you commence 
construction of the affected source after September 11, 1998, and you 
meet the applicability criteria in Sec. 63.1561 at the time you 
commenced construction.
    (d) Any affected source is reconstructed if you meet the criteria in 
Sec. 63.2.
    (e) An affected source is existing if it is not new or 
reconstructed.
    (f) This subpart does not apply to:
    (1) A thermal catalytic cracking unit.
    (2) A sulfur recovery unit that does not recover elemental sulfur or 
where the modified reaction is carried out in a water solution which 
contains a metal ion capable of oxidizing the sulfide ion to sulfur 
(e.g., the LO-CAT II process).
    (3) A redundant sulfur recovery unit not located at a petroleum 
refinery and used by the refinery only for emergency or maintenance 
backup.
    (4) Equipment associated with bypass lines such as low leg drains, 
high point bleed, analyzer vents, open-ended valves or lines, or 
pressure relief valves needed for safety reasons.
    (5) Gaseous streams routed to a fuel gas system.

[67 FR 17773, Apr. 11, 2002, as amended at 70 FR 6938, Feb. 9, 2005]



Sec. 63.1563  When do I have to comply with this subpart?

    (a) If you have a new or reconstructed affected source, you must 
comply with this subpart according to the requirements in paragraphs 
(a)(1) and (2) of this section.
    (1) If you startup your affected source before April 11, 2002, then 
you must comply with the emission limitations and work practice 
standards for new and reconstructed sources in this subpart no later 
than April 11, 2002.
    (2) If you startup your affected source after April 11, 2002, you 
must comply with the emission limitations and work practice standards 
for new and reconstructed sources in this subpart upon startup of your 
affected source.
    (b) If you have an existing affected source, you must comply with 
the emission limitations and work practice standards for existing 
affected sources in this subpart by no later than April 11, 2005 except 
as specified in paragraph (c) of this section.
    (c) We will grant an extension of compliance for an existing 
catalytic cracking unit allowing additional time to meet the emission 
limitations and work practice standards for catalytic cracking units in 
Sec. Sec. 63.1564 and 63.1565 if you commit to hydrotreating the 
catalytic cracking unit feedstock and to meeting the emission 
limitations of this subpart on the same date that your facility meets 
the final Tier 2 gasoline sulfur control standard (40 CFR

[[Page 110]]

part 80, subpart J). To obtain an extension, you must submit a written 
notification to your permitting authority according to the requirements 
in Sec. 63.1574(e). Your notification must include the information in 
paragraphs (c)(1) and (2) of this section.
    (1) Identification of the affected source with a brief description 
of the controls to be installed (if needed) to comply with the emission 
limitations for catalytic cracking units in this subpart.
    (2) A compliance schedule, including the information in paragraphs 
(c)(2)(i) through (iv) of this section.
    (i) The date by which onsite construction or the process change is 
to be initiated.
    (ii) The date by which onsite construction or the process change is 
to be completed.
    (iii) The date by which your facility will achieve final compliance 
with both the final Tier 2 gasoline sulfur control standard as specified 
in Sec. 80.195, and the emission limitations and work practice 
standards for catalytic cracking units in this subpart. In no case will 
your permitting authority grant an extension beyond the date you are 
required to meet the Tier 2 gasoline sulfur control standard or December 
31, 2009, whichever comes first. If you don't comply with the emission 
limitations and work practice standards for existing catalytic cracking 
units by the specified date, you will be out-of-compliance with the 
requirements for catalytic cracking units beginning April 11, 2005.
    (iv) A brief description of interim emission control measures that

malfunction are

[[Page 121]]

violations, according to the provisions in Sec. 63.6(e).

[67 FR 17773, Apr. 11, 2002, as amended at 71 FR 20462, Apr. 20, 2006]



Sec. 63.1571  How and when do I conduct a performance test or other
initial compliance demonstration?

    (a) When must I conduct a performance test? You must conduct 
performance tests and report the results by no later than 150 days after 
the compliance date specified for your source in Sec. 63.1563 and 
according to the provisions in Sec. 63.7(a)(2). If you are required to 
do a performance evaluation or test for a semi-regenerative catalytic 
reforming unit catalyst regenerator vent, you may do them at the first 
regeneration cycle after your compliance date and report the results in 
a followup Notification of Compliance Status report due no later than 
150 days after the test.
    (1) For each emission limitation or work practice standard where 
initial compliance is not demonstrated using a performance test, opacity 
observation, or visible emission observation, you must conduct the 
initial compliance demonstration within 30 calendar days after the 
compliance date that is specified for your source in Sec. 63.1563.
    (2) For each emission limitation where the averaging period is 30 
days, the 30-day period for demonstrating initial compliance begins at 
12:00 a.m. on the compliance date that is specified for your source in 
Sec. 63.1563 and ends at 11:59 p.m., 30 calendar days after the 
compliance date that is specified for your source in Sec. 63.1563.
    (3) If you commenced construction or reconstruction between 
September 11, 1998 and April 11, 2002, you must demonstrate initial 
compliance with either the proposed emission limitation or the 
promulgated emission limitation no later than October 8, 2002 or within 
180 calendar days after startup of the source, whichever is later, 
according to Sec. 63.7(a)(2)(ix).
    (4) If you commenced construction or reconstruction between 
September 11, 1998 and April 11, 2002, and you chose to comply with the 
proposed emission limitation when demonstrating initial compliance, you 
must conduct a second compliance demonstration for the promulgated 
emission limitation by October 10, 2005, or after startup of the source, 
whichever is later, according to Sec. 63.7(a)(2)(ix).
    (b) What are the general requirements for performance test and 
performance evaluations? You must:
    (1) Conduct each performance test according to the requirements in 
Sec. 63.7(e)(1).
    (2) Except for opacity and visible emission observations, conduct 
three separate test runs for each performance test as specified in Sec. 
63.7(e)(3). Each test run must last at least 1 hour.
    (3) Conduct each performance evaluation according to the 
requirements in Sec. 63.8(e).
    (4) Not conduct performance tests during periods of startup, 
shutdown, or malfunction, as specified in Sec. 63.7(e)(1).
    (5) Calculate the average emission rate for the performance test by 
calculating the emission rate for each individual test run in the units 
of the applicable emission limitation using Equation 2, 5, or 8 of Sec. 
63.1564, and determining the arithmetic average of the calculated 
emission rates.
    (c) What procedures must I use for an engineering assessment? You 
may choose to use an engineering assessment to calculate the process 
vent flow rate, net heating value, TOC emission rate, and total organic 
HAP emission rate expected to yield the highest daily emission rate when 
determining the emission reduction or outlet concentration for the 
organic HAP standard for catalytic reforming units. If you use an 
engineering assessment, you must document all data, assumptions, and 
procedures to the satisfaction of the applicable permitting authority. 
An engineering assessment may include the approaches listed in 
paragraphs (c)(1) through (c)(4) of this section. Other engineering 
assessments may be used but are subject to review and approval by the 
applicable permitting authority.
    (1) You may use previous test results provided the tests are 
representative of current operating practices at the process unit, and 
provided EPA methods or approved alternatives were used;
    (2) You may use bench-scale or pilot-scale test data representative 
of the process under representative operating conditions;

[[Page 122]]

    (3) You may use maximum flow rate, TOC emission rate, organic HAP 
emission rate, or organic HAP or TOC concentration specified or implied 
within a permit limit applicable to the process vent; or
    (4) You may use design analysis based on engineering principles, 
measurable process parameters, or physical or chemical laws or 
properties. Examples of analytical methods include, but are not limited 
to:
    (i) Use of material balances based on process stoichiometry to 
estimate maximum TOC concentrations;
    (ii) Calculation of hourly average maximum flow rate based on 
physical equipment design such as pump or blower capacities; and
    (iii) Calculation of TOC concentrations based on saturation 
conditions.
    (d) Can I adjust the process or control device measured values when 
establishing an operating limit? If you do a performance test to 
demonstrate compliance, you must base the process or control device 
operating limits for continuous parameter monitoring systems on the 
results measured during the performance test. You may adjust the values 
measured during the performance test according to the criteria in 
paragraphs (d)(1) through (3) of this section.
    (1) If you must meet the HAP metal emission limitations in Sec. 
63.1564, you elect the option in paragraph (a)(1)(iii) in Sec. 63.1564 
(Ni lb/hr), and you use continuous parameter monitoring systems, you 
must establish an operating limit for the equilibrium catalyst Ni 
concentration based on the laboratory analysis of the equilibrium 
catalyst Ni concentration from the initial performance test. Section 
63.1564(b)(2) allows you to adjust the laboratory measurements of the 
equilibrium catalyst Ni concentration to the maximum level. You must 
make this adjustment using Equation 1 of this section as follows:
[GRAPHIC] [TIFF OMITTED] TR11AP02.017

Where:

Ecat-Limit = Operating limit for equilibrium catalyst Ni concentration, 
          mg/kg;
NiEmR1st = Average Ni emission rate calculated as the 
          arithmetic average Ni emission rate using Equation 5 of this 
          section for each performance test run, g Ni/hr; and
Ecatst = Average equilibrium Ni concentration from laboratory 
          test results, mg/kg.

    (2) If you must meet the HAP metal emission limitations in Sec. 
63.1564, you elect the option in paragraph (a)(1)(iv) in Sec. 63.1564 
(Ni lb/1,000 lb of coke burn-off), and you use continuous parameter 
monitoring systems, you must establish an operating limit for the 
equilibrium catalyst Ni concentration based on the laboratory analysis 
of the equilibrium catalyst Ni concentration from the initial 
performance test. Section 63.1564(b)(2) allows you to adjust the 
laboratory measurements of the equilibrium catalyst Ni concentration to 
the maximum level. You must make this adjustment using Equation 2 of 
this section as follows:
[GRAPHIC] [TIFF OMITTED] TR11AP02.018

Where:

NiEmR2st = Average Ni emission rate calculated as the 
          arithmetic average Ni emission rate using Equation 8 of Sec. 
          63.1564 for each performance test run, mg/kg coke burn-off.

    (3) If you choose to adjust the equilibrium catalyst Ni 
concentration to the maximum level, you can't adjust

[[Page 123]]

any other monitored operating parameter (i.e., gas flow rate, voltage, 
pressure drop, liquid-to-gas ratio).
    (4) Except as specified in paragraph (d)(3) of this section, if you 
use continuous parameter monitoring systems, you may adjust one of your 
monitored operating parameters (flow rate, voltage and secondary 
current, pressure drop, liquid-to-gas ratio) from the average of 
measured values during the performance test to the maximum value (or 
minimum value, if applicable) representative of worst-case operating 
conditions, if necessary. This adjustment of measured values may be done 
using control device design specifications, manufacturer 
recommendations, or other applicable information. You must provide 
supporting documentation and rationale in your Notification of 
Compliance Status, demonstrating to the satisfaction of your permitting 
authority, that your affected source complies with the applicable 
emission limit at the operating limit based on adjusted values.
    (e) Can I change my operating limit? You may change the established 
operating limit by meeting the requirements in paragraphs (e)(1) through 
(3) of this section.
    (1) You may change your established operating limit for a continuous 
parameter monitoring system by doing an additional performance test, a 
performance test in conjunction with an engineering assessment, or an 
engineering assessment to verify that, at the new operating limit, you 
are in compliance with the applicable emission limitation.
    (2) You must establish a revised operating limit for your continuous 
parameter monitoring system if you make any change in process or 
operating conditions that could affect control system performance or you 
change designated conditions after the last performance or compliance 
tests were done. You can establish the revised operating limit as 
described in paragraph (e)(1) of this section.
    (3) You may change your site-specific opacity operating limit or Ni 
operating limit only by doing a new performance test.

(1) You may use this alternative to a continuous parameter monitoring 
system for the catalytic regenerator exhaust gas flow rate for your 
catalytic cracking unit if the unit does not introduce any other gas 
streams into the catalyst regeneration vent (i.e., complete combustion 
units with no additional combustion devices). You may also use this 
alternative to a continuous parameter monitoring system for the 
catalytic regenerator atmospheric exhaust gas flow rate for your 
catalytic reforming unit during the coke burn and rejuvenation cycles if 
the unit operates as a constant pressure system during these cycles. If 
you use this alternative, you shall use the same procedure for the 
performance test and for monitoring after the performance test. You 
shall:
    (i) Install and operate a continuous parameter monitoring system to 
measure and record the hourly average volumetric air flow rate to the 
catalytic cracking unit or catalytic reforming unit regenerator. Or, you 
may determine and record the hourly average volumetric air flow rate to 
the catalytic cracking unit or catalytic reforming unit regenerator 
using the appropriate control room instrumentation.
    (ii) Install and operate a continuous parameter monitoring system to 
measure and record the temperature of the gases entering the control 
device (or exiting the catalyst regenerator if you do not use an add-on 
control device).

[[Page 125]]

    (iii) Calculate and record the hourly average actual exhaust gas 
flow rate using Equation 1 of this section as follows:
[GRAPHIC] [TIFF OMITTED] TR09FE05.008

Where

Q gas = Hourly average actual gas flow rate, acfm;
1.12 = Default correction factor to convert gas flow from dry standard 
          cubic feet per minute (dscfm) to standard cubic feet per 
          minute (scfm);
Q air = Volumetric flow rate of air to regenerator, as 
          determined from the control room instrumentations, dscfm;
Q other = Volumetric flow rate of other gases entering the 
          regenerator as determined from the control room 
          instrumentations, dscfm. (Examples of ``other'' gases include 
          an oxygen-enriched air stream to catalytic cracking unit 
          regenerators and a nitrogen stream to catalytic reforming unit 
          regenerators.);
Tempgas = Temperature of gas stream in vent measured as near 
          as practical to the control device or opacity monitor, [deg]K. 
          For wet scrubbers, temperature of gas prior to the wet 
          scrubber; and
Pvent = Absolute pressure in the vent measured as near as 
          practical to the control device or opacity monitor, as 
          applicable, atm. When used to assess the gas flow rate in the 
          final atmospheric vent stack, you can assume Pvent 
          = 1 atm.

    (2) You may use this alternative to calculating Q r, the 
volumetric flow rate of exhaust gas for the catalytic cracking 
regenerator as required in Equation 1 of Sec. 63.1564, if you have a 
gas analyzer installed in the catalytic cracking regenerator exhaust 
vent prior to the addition of air or other gas streams. You may measure 
upstream or downstream of an electrostatic precipitator, but you shall 
measure upstream of a carbon monoxide boiler. You shall:
    (i) Install and operate a continuous parameter monitoring system to 
measure and record the hourly average volumetric air flow rate to the 
catalytic cracking unit regenerator. Or, you can determine and record 
the hourly average volumetric air flow rate to the catalytic cracking 
unit regenerator using the catalytic cracking unit control room 
instrumentation.
    (ii) Install and operate a continuous gas analyzer to measure and 
record the concentration of carbon dioxide, carbon monoxide, and oxygen 
of the catalytic cracking regenerator exhaust.
    (iii) Calculate and record the hourly average flow rate using 
Equation 2 of this section as follows:
[GRAPHIC] [TIFF OMITTED] TR09FE05.009

Where:

Q r = Volumetric flow rate of exhaust gas from the catalyst 
          regenerator before adding air or gas streams, dscm/min (dscf/
          min);
79 = Default concentration of nitrogen and argon in dry air, percent by 
          volume (dry basis);
%Oxy = Oxygen concentration in oxygen-enriched air stream, 
          percent by volume (dry basis);
Q oxy = Volumetric flow rate of oxygen-enriched air stream to 
          regenerator as determined from the catalytic cracking unit 
          control room instrumentations, dscm/min (dscf/min);
%CO2 = Carbon dioxide concentration in regenerator exhaust, 
          percent by volume (dry basis);
CO = Carbon monoxide concentration in regenerator exhaust, percent by 
          volume (dry basis); and
%O2 = Oxygen concentration in regenerator exhaust, percent by 
          volume (dry basis).

    (b) What is the approved alternative for monitoring pH or alkalinity 
levels? You may use the alternative in paragraph (b)(1) or (2) of this 
section for a catalytic reforming unit.
    (1) You shall measure and record the pH of the water (or scrubbing 
liquid) exiting the wet scrubber or internal scrubbing system at least 
once an hour during coke burn-off and catalyst rejuvenation using pH 
strips as an alternative to a continuous parameter monitoring system. 
The pH strips must meet the requirements in Table 41 of this subpart.
    (2) You shall measure and record the alkalinity of the water (or 
scrubbing liquid) exiting the wet scrubber or internal scrubbing system 
at least once an hour during coke burn-off and catalyst rejuvenation 
using titration as an alternative to a continuous parameter monitoring 
system.
    (c) Can I use another type of monitoring system? You may request 
approval from your permitting authority to use an automated data 
compression system. An automated data compression system does not record 
monitored operating parameter values at a set frequency (e.g., once 
every hour) but records all values that meet set criteria for variation 
from previously recorded values. Your request must contain a description 
of the monitoring system and data recording system, including the 
criteria used to determine which monitored values are recorded and 
retained, the method for calculating daily averages, and a demonstration 
that the system meets all of the criteria in paragraphs (c)(1) through 
(5) of this section:
    (1) The system measures the operating parameter value at least once 
every hour;
    (2) The system records at least 24 values each day during periods of 
operation;
    (3) The system records the date and time when monitors are turned 
off or on;
    (4) The system recognizes unchanging data that may indicate the 
monitor is not functioning properly, alerts the operator, and records 
the incident; and
    (5) The system computes daily average values of the monitored 
operating parameter based on recorded data.
    (d) Can I monitor other process or control device operating 
parameters? You may request approval to monitor parameters other than 
those required in this subpart. You must request approval if:
    (1) You use a control device other than a thermal incinerator, 
boiler, process heater, flare, electrostatic precipitator, or wet 
scrubber;
    (2) You use a combustion control device (e.g., incinerator, flare, 
boiler or process heater with a design heat capacity of at least 44 MW, 
boiler or process heater where the vent stream is introduced into the 
flame zone), electrostatic precipitator, or scrubber but want to monitor 
a parameter other than those specified; or
    (3) You wish to use another type of continuous emission monitoring 
system that provides direct measurement of a pollutant (i.e., a PM or 
multi-metals HAP continuous emission monitoring system, a carbonyl 
sulfide/carbon disulfide continuous emission monitoring system, a TOC 
continuous emission monitoring system, or HCl continuous emission 
monitoring system).
    (e) How do I request to monitor alternative parameters? You must 
submit a request for review and approval or disapproval to the 
Administrator. The request must include the information in paragraphs 
(e)(1) through (5) of this section.
    (1) A description of each affected source and the parameter(s) to be 
monitored to determine whether the affected source will continuously 
comply with the emission limitations and an explanation of the criteria 
used to select the parameter(s).
    (2) A description of the methods and procedures that will be used to 
demonstrate that the parameter can be used to determine whether the 
affected source will continuously comply with the emission limitations 
and the schedule for this demonstration. You must certify that you will 
establish an operating limit for the monitored parameter(s) that 
represents the conditions in existence when the control device is being 
properly operated and maintained to meet the emission limitation.
    (3) The frequency and content of monitoring, recording, and 
reporting, if

[[Page 127]]

monitoring and recording are not continuous. You also must include the 
rationale for the proposed monitoring, recording, and reporting 
requirements.
    (4) Supporting calculations.
    (5) Averaging time for the alternative operating parameter.
    (f) How do I apply for alternative monitoring requirements if my 
catalytic cracking unit is equipped with a wet scrubber and I have 
approved alternative monitoring requirements under the new source 
performance standards for petroleum refineries? (1) You may request 
alternative monitoring requirements according to the procedures in this 
paragraph if you meet each of the conditions in paragraphs (f)(1)(i) 
through (iii) of this section:
    (i) Your fluid catalytic cracking unit regenerator vent is subject 
to the PM limit in 40 CFR 60.102(a)(1) and uses a wet scrubber for PM 
emissions control;
    (ii) You have alternative monitoring requirements for the continuous 
opacity monitoring system requirement in 40 CFR 60.105(a)(1) approved by 
the Administrator; and
    (iii) You are required by this subpart to install, operate, and 
maintain a continuous opacity monitoring system for the same catalytic 
cracking unit regenerator vent for which you have approved alternative 
monitoring requirements.
    (2) You can request approval to use an alternative monitoring method 
prior to submitting your notification of compliance status, in your 
notification of compliance status, or at any time.
    (3) You must submit a copy of the approved alternative monitoring 
requirements along with a monitoring plan that includes a description of 
the continuous monitoring system or method, including appropriate 
operating parameters that will be monitored, test results demonstrating 
compliance with the opacity limit used to establish an enforceable 
operating limit(s), and the frequency of measuring and recording to 
establish continuous compliance. If applicable, you must also include 
operation and maintenance requirements for the continuous monitoring 
system.
    (4) We will contact you within 30 days of receipt of your 
application to inform you of approval or of our intent to disapprove 
your request.

                   Notifications, Reports, and Records



Sec. 63.1574  What notifications must I submit and when?

    (a) Except as allowed in paragraphs (a)(1) through (3) of this 
section, you must submit all of the notifications in Sec. Sec. 63.6(h), 
63.7(b) and (c), 63.8(e), 63.8(f)(4), 63.8(f)(6), and 63.9(b) through 
(h) that apply to you by the dates specified.
    (1) You must submit the notification of your intention to construct 
or reconstruct according to Sec. 63.9(b)(5) unless construction or 
reconstruction had commenced and initial startup had not occurred before 
April 11, 2002. In this case, you must submit the notification as soon 
as practicable before startup but no later than July 10, 2002. This 
deadline also applies to the application for approval of construction or 
reconstruction and approval of construction or reconstruction based on 
State preconstruction review required in Sec. Sec. 63.5(d)(1)(i) and 
63.5(f)(2).
    (2) You must submit the notification of intent to conduct a 
performance test required in Sec. 63.7(b) at least 30 calendar days 
before the performance test is scheduled to begin (instead of 60 days).
    (3) If you are required to conduct a performance test, performance 
evaluation, design evaluation, opacity observation, visible emission 
observation, or other initial compliance demonstration, you must submit 
a notification of compliance status according to Sec. 63.9(h)(2)(ii). 
You can submit this information in an operating permit application, in 
an amendment to an operating permit application, in a separate 
submission, or in any combination. In a State with an approved operating 
permit program where delegation of authority under section 112(l) of the 
CAA has not been requested or approved, you must provide a duplicate 
notification to the applicable Regional Administrator. If the required 
information has been submitted previously, you do not have to provide a 
separate notification of compliance status. Just refer to the earlier 
submissions instead

[[Page 128]]

of duplicating and resubmitting the previously submitted information.
    (i) For each initial compliance demonstration that does not include 
a performance test, you must submit the Notification of Compliance 
Status no later than 30 calendar days following completion of the 
initial compliance demonstration.
    (ii) For each initial compliance demonstration that includes a 
performance test, you must submit the notification of compliance status, 
including the performance test results, no later than 150 calendar days 
after the compliance date specified for your affected source in Sec. 
63.1563.
    (b) As specified in Sec. 63.9(b)(2), if you startup your new

notification no later than August 9, 2002.
    (c) If you startup your new or reconstructed affected source on or 
after April 11, 2002, you must submit the initial notification no later 
than 120 days after you become subject to this subpart.
    (d) You also must include the information in Table 42 of this 
subpart in your notification of compliance status.
    (e) If you request an extension of compliance for an existing 
catalytic cracking unit as allowed in Sec. 63.1563(c), you must submit 
a notification to your permitting authority containing the required 
information by October 13, 2003.
    (f) As required by this subpart, you must prepare and implement an 
operation, maintenance, and monitoring plan for each control system and 
continuous monitoring system for each affected source. The purpose of 
this plan is to detail the operation, maintenance, and monitoring 
procedures you will follow.
    (1) You must submit the plan to your permitting authority for review 
and approval along with your notification of compliance status. While 
you do not have to include the entire plan in your part 70 or 71 permit, 
you must include the duty to prepare and implement the plan as an 
applicable requirement in your part 70 or 71 operating permit. You must 
submit any changes to your permitting authority for review and approval 
and comply with the plan until the change is approved.
    (2) Each plan must include, at a minimum, the information specified 
in paragraphs (f)(2)(i) through (xii) of this section.
    (i) Process and control device parameters to be monitored for each 
affected source, along with established operating limits.
    (ii) Procedures for monitoring emissions and process and control 
device operating parameters for each affected source.
    (iii) Procedures that you will use to determine the coke burn-rate, 
the volumetric flow rate (if you use process data rather than direct 
measurement), and the rate of combustion of liquid or solid fossil fuels 
if you use an incinerator-waste heat boiler to burn the exhaust gases 
from a catalyst regenerator.
    (iv) Procedures and analytical methods you will use to determine the 
equilibrium catalyst Ni concentration, the equilibrium catalyst Ni 
concentration monthly rolling average, and the hourly or hourly average 
Ni operating value.
    (v) Procedures you will use to determine the pH of the water (or 
scrubbing liquid) exiting a wet scrubber if you use pH strips.
    (vi) Procedures you will use to determine the HCl concentration of 
gases from a catalytic reforming unit when you use a colormetric tube 
sampling system, including procedures for correcting for pressure (if 
applicable to the sampling equipment) and the sampling locations that 
will be used for compliance monitoring purposes.
    (vii) Procedures you will use to determine the gas flow rate for a 
catalytic cracking unit if you use the alternative procedure based on 
air flow rate and temperature.
    (viii) Monitoring schedule, including when you will monitor and when 
you will not monitor an affected source (e.g., during the coke burn-off, 
regeneration process).
    (ix) Quality control plan for each continuous opacity monitoring 
system and continuous emission monitoring system you use to meet an 
emission limit in this subpart. This plan must include procedures you 
will use for

[[Page 129]]

calibrations, accuracy audits, and adjustments to the system needed to 
meet applicable requirements for the system.
    (x) Maintenance schedule for each monitoring system and control 
device for each affected source that is generally consistent with the 
manufacturer's instructions for routine and long-term maintenance.
    (xi) If you use a fixed-bed gas-solid adsorption system to control 
emissions from a catalytic reforming unit, you must implement corrective 
action procedures if the HCl concentration measured at the selected 
compliance monitoring sampling location within the bed exceeds the 
operating limit. These procedures must require, at minimum, repeat 
measurement and recording of the HCl concentration in the adsorption 
system exhaust gases and at the selected compliance monitoring sampling 
location within the bed. If the HCl concentration at the selected 
compliance monitoring location within the bed is above the operating 
limit during the repeat measurement while the HCl concentration in the 
adsorption system exhaust gases remains below the operating limit, the 
adsorption bed must be replaced as soon as practicable. Your procedures 
must specify the sampling frequency that will be used to monitor the HCl 
concentration in the adsorption system exhaust gases subsequent to the 
repeat measurement and prior to replacement of the sorbent material (but 
not less frequent than once every 4 hours during coke burn-off). If the 
HCl concentration of the adsorption system exhaust gases is above the 
operating limit when measured at any time, the adsorption bed must be 
replaced within 24 hours or before the next regeneration cycle, 
whichever is longer.
    (xii) Procedures that will be used for purging the catalyst if you 
do not use a control device to comply with the organic HAP emission 
limits for catalytic reforming units. These procedures will include, but 
are not limited to, specification of the minimum catalyst temperature 
and the minimum cumulative volume of gas per mass of catalyst used for 
purging prior to uncontrolled releases (i.e., during controlled purging 
events); the maximum purge gas temperature for uncontrolled purge 
events; and specification of the monitoring systems that will be used to 
monitor and record data during each purge event.

authority demonstrating that the period of planned maintenance results 
in overall emissions reductions. During this pre-approved time period, 
the emission control device may be taken out of service while 
maintenance is performed on the control device and/or one of the process 
units while the remaining process unit(s) continue to operate. During 
the period the emission control device is unable to operate, the 
emission limits, operating limits, and monitoring requirements 
applicable to the unit that is operating and the wet scrubber emission 
control device do not apply. The applicable permitting authority may 
require that you take specified actions to minimize emissions during the 
period of planned maintenance.
    (1) You must submit a written request to the applicable permitting 
authority at least 6 months before the planned maintenance is scheduled

flowing through the remaining reactors without change in feed rate or 
product octane).
    Deviation means any instance in which an affected source subject to 
this subpart, or an owner or operator of such a source:
    (1) Fails to meet any requirement or obligation established by this 
subpart, including but not limited to any emission limit, operating

Methods 5B or 5F in appendix A to part 60 of this chapter or by an 
approved alternative method.
    Process heater means an enclosed combustion device that primarily 
transfers heat liberated by burning fuel directly to process streams or 
to heat transfer liquids other than water.

sulfur from gases that contain reduced sulfur compounds and other 
pollutants, usually by a vapor-phase catalytic reaction of sulfur 
dioxide and hydrogen sulfide. This definition does not include a unit 
where the modified reaction is carried out in a water solution which 
contains a metal ion capable of oxidizing the sulfide ion to sulfur, 
e.g., the LO-CAT II process.

organic compounds that serve as a surrogate measure of the total 
emissions of organic HAP compounds including, but not limited to, 
acetaldehyde, benzene, hexane, phenol, toluene, and xylenes and nonHAP 
VOC as measured by Method 25A in appendix A to part 60 of this chapter 
or by an approved alternative method.
    TRS means, for the purposes of this subpart, emissions of total 
reduced sulfur compounds, expressed as an equivalent sulfur dioxide 
concentration, that serve as a surrogate measure of the total emissions 
of sulfide HAP carbonyl sulfide and carbon disulfide as measured by

[[Page 180]]

    1.2 Applicability. This method is applicable to the determination of 
analyte concentrations on catalyst particles. This method is applicable 
for catalyst particles obtained from the fluid catalytic cracking unit 
(FCCU) regenerator (i.e., equilibrium catalyst), from air pollution 
control systems operated for the FCCU catalyst regenerator vent (FCCU 
fines), from catalytic reforming units (CRU), and other processes as 
specified within an applicable regulation. This method is applicable 
only when specified within the regulation.
    1.3 Data Quality Objectives. Adherence to the requirements of this 
method will enhance the quality of the data obtained from the analytical 
method.

                         2.0 Summary of Method.

    2.1 A representative sample of catalyst particles is collected, 
prepared, and analyzed for analyte concentration using either energy or 
wavelength dispersive X-ray flourescent (XRF) spectrometry instrumental 
analyzers. In both types of XRF spectrometers, the instrument irradiates 
the sample with high energy (primary) x-rays and the elements in the 
sample absorb the x-rays and then re-emit secondary (fluorescent) x-rays 
of characteristic wavelengths for each element present. In energy 
dispersive XRF spectrometers, all secondary x-rays (of all wavelengths) 
enter the detector at once. The detector registers an electric current 
having a height proportional to the photon energy, and these pulses are 
then separated electronically, using a pulse analyzer. In wavelength 
dispersive XRF spectrometers, the secondary x-rays are dispersed 
spatially by crystal diffraction on the basis of wavelength. The crystal 
and detector are made to synchronously rotate and the detector then 
receives only one wavelength at a time. The intensity of the x-rays 
emitted by each element is proportional to its concentration, after 
correcting for matrix effects. For nickel compounds and total chlorides, 
the XRF instrument response is expected to be linear to analyte 
concentration. Performance specifications and test procedures are 
provided to ensure reliable data.

                            3.0 Definitions.

    3.1 Measurement System. The total equipment required for the 
determination of analyte concentration. The measurement system consists 
of the following major subsystems:
    3.1.1 Sample Preparation. That portion of a system used for one or 
more of the following: sample acquisition, sample transport, sample 
conditioning, or sample preparation prior to introducing the sample into 
the analyzer.
    3.1.2 Analyzer. That portion of the system that senses the analyte 
to be measured and generates an output proportional to its 
concentration.
    3.1.3 Data Recorder. A digital recorder or personal computer used 
for recording measurement data from the analyzer output.
    3.2 Span. The upper limit of the gas concentration measurement range 
displayed on the data recorder.
    3.3 Calibration Standards. Prepared catalyst samples or other 
samples of known analyte concentrations used to calibrate the analyzer 
and to assess calibration drift.
    3.4 Energy Calibration Standard. Calibration standard, generally 
provided by the XRF instrument manufacturer, used for assuring accuracy 
of the energy scale.
    3.5 Accuracy Assessment Standard. Prepared catalyst sample or other 
sample of known analyte concentrations used to assess analyzer accuracy 
error.
    3.6 Zero Drift. The difference in the measurement system output 
reading from the initial value for zero concentration level calibration 
standard after a stated period of operation during which no unscheduled 
maintenance, repair, or adjustment took place.
    3.7 Calibration Drift. The difference in the measurement system 
output reading from the initial value for the mid-range calibration 
standard after a stated period of operation during which no unscheduled 
maintenance, repair, or adjustment took place.
    3.8 Spectral Interferences. Analytical interferences and excessive 
biases caused by elemental peak overlap, escape peak, and sum peak 
interferences between elements in the samples.
    3.9 Calibration Curve. A graph or other systematic method of 
establishing the relationship between the analyzer response and the 
actual analyte concentration introduced to the analyzer.
    3.10 Analyzer Accuracy Error. The difference in the measurement 
system output reading and the ideal value for the accuracy assessment 
standard.

                           4.0 Interferences.

    4.1 Spectral interferences with analyte line intensity determination 
are accounted for within the method program. No action is required by 
the XRF operator once these interferences have been addressed within the 
method.
    4.2 The X-ray production efficiency is affected by particle size for 
the very lightest elements. However, particulate matter (PM) 2.5 
particle size effects are substantially < 1 percent for most elements. 
The calibration standards should be prepared with material of similar 
particle size or be processed (ground) to produce material of similar 
particle size as the catalyst samples to be analyzed. No additional 
correction for particle size is performed. Alternatively, the sample can 
be fused in order to eliminate any potential particle size effects.

[[Page 181]]

                               5.0 Safety.

    5.1 Disclaimer. This method may involve hazardous materials, 
operations, and equipment. This test method may not address all of the 
safety problems associated with its use. It is the responsibility of the 
user of this test method to establish appropriate safety and health 
practices and determine the applicability of regulatory limitations 
prior to performing this test method.
    5.2 X-ray Exposure. The XRF uses X-rays; XRF operators should follow 
instrument manufacturer's guidelines to protect from accidental exposure 
to X-rays when the instrument is in operation.
    5.3 Beryllium Window. In most XRF units, a beryllium (Be) window is 
present to separate the sample chamber from the X-ray tube and detector. 
The window is very fragile and brittle. Do not allow sample or debris to 
fall onto the window, and avoid using compressed air to clean the window 
because it will cause the window to rupture. If the window should 
rupture, note that Be metal is poisonous. Use extreme caution when 
collecting pieces of Be and consult the instrument manufacturer for 
advice on cleanup of the broken window and replacement.

                       6.0 Equipment and Supplies.

    6.1 Measurement System. Use any measurement system that meets the 
specifications of this method listed in section 13. The typical 
components of the measurement system are described below.
    6.1.1 Sample Mixer/Mill. Stainless steel, or equivalent to grind/mix 
catalyst and binders, if used, to produce uniform particle samples.
    6.1.2 Sample Press/Fluxer. Stainless steel, or equivalent to produce 
pellets of sufficient size to fill analyzer sample window, or 
alternatively, a fusion device capable of preparing a fused disk of 
sufficient size to fill analyzer sample window.
    6.1.3 Analytical Balance. 0.0001 gram accuracy 
for weighing prepared samples (pellets).
    6.1.4 Analyzer. An XRF spectrometer to determine the analyte 
concentration in the prepared sample. The analyzer must meet the 
applicable performance specifications in section 13.
    6.1.5 Data Recorder. A digital recorder or personal computer for 
recording measurement data. The data recorder resolution (i.e., 
readability) must be 0.5 percent of span. Alternatively, a digital or 
analog meter having a resolution of 0.5 percent of span may be used to 
obtain the analyzer responses and the readings may be recorded manually.

                       7.0 Reagents and Standards.

    7.1 Calibration Standards. The calibration standards for the 
analyzer must be prepared catalyst samples or other material of similar 
particle size and matrix as the catalyst samples to be tested that have 
known concentrations of the analytes of interest. Preparation (grinding/
milling/fusion) of the calibration standards should follow the same 
processes used to prepare the catalyst samples to be tested. The 
calibration standards values must be established as the average of a 
minimum of three analyses using an approved EPA or ASTM method with 
instrument analyzer calibrations traceable to the U.S. National 
Institute of Standards and Technology (NIST), if available. The maximum 
percent deviation of the triplicate calibration standard analyses should 
agree within 10 percent of the average value for the triplicate analysis 
(see Figure 1). If the calibration analyses do not meet this criteria, 
the calibration standards must be re-analyzed. If unacceptable 
variability persists, new calibration standards must be prepared. 
Approved methods for the calibration standard analyses include, but are 
not limited to, EPA Methods 6010B, 6020, 7520, or 7521 of SW-846.\1\ Use 
a minimum of four calibration standards as specified below (see Figure 
1):
    7.1.1 High-Range Calibration Standard. Concentration equivalent to 
80 to 100 percent of the span. The concentration of the high-range 
calibration standard should exceed the maximum concentration anticipated 
in the catalyst samples.
    7.1.2 Mid-Range Calibration Standard. Concentration equivalent to 40 
to 60 percent of the span.
    7.1.3 Low-Range Calibration Standard. Concentration equivalent to 1 
to 20 percent of the span. The concentration of the low-range 
calibration standard should be selected so that it is less than either 
one-forth of the applicable concentration limit or of the lowest 
concentration anticipated in the catalyst samples.
    7.1.4 Zero Calibration Standard. Concentration of less than 0.25 
percent of the span.
    7.2 Accuracy Assessment Standard. Prepare an accuracy assessment 
standard and determine the ideal value for the accuracy assessment 
standard following the same procedures used to prepare and analyze the 
calibration standards as described in section 7.1. The maximum percent 
deviation of the triplicate accuracy assessment standard analyses should 
agree within 10 percent of the average value for the triplicate analysis 
(see Figure 1). The concentration equivalent of the accuracy assessment 
standard must be between 20 and 80 percent of the span.
    7.3 Energy Calibration Standard. Generally, the energy calibration 
standard will be provided by the XRF instrument manufacturer for energy 
dispersive spectrometers. Energy calibration is performed using the 
manufacturer's recommended calibration standard and involves measurement 
of a specific energy line (based on the metal in the

[[Page 182]]

energy calibration standard). This is generally an automated procedure 
used to assure the accuracy of the energy scale. This calibration 
standard may not be applicable to all models of XRF spectrometers 
(particularly wavelength dispersive XRF spectrometers).

 8.0 Sample Collection, Preservation, Transport, and Storage. [Reserved]

                          9.0 Quality Control.

    9.1 Energy Calibration. For energy dispersive spectrometers, conduct 
the energy calibration by analyzing the energy calibration standard 
provided by the manufacturer. The energy calibration involves 
measurement of a specific energy line (based on the metal in the energy 
calibration standard) and then determination of the difference between 
the measured peak energy value and the ideal value. This analysis, if 
applicable, should be performed daily prior to any sample analyses to 
check the instrument's energy scale. This is generally an automated 
procedure and assures the accuracy of the energy scale. If the energy 
scale calibration process is not automated, follow the manufacturer's 
procedures to manually adjust the instrument, as necessary.
    9.2 Zero Drift Test. Conduct the zero drift test by analyzing the 
analyte concentration output by the measurement system with the initial 
calibration value for the zero calibration standard (see Figure 2). This 
analysis should be performed with each set of samples analyzed.
    9.3 Calibration Drift Test. Conduct the calibration drift test by 
analyzing the analyte concentration output by the measurement system 
with the initial calibration value for the mid-range calibration 
standard (see Figure 2). This analysis should be performed with each set 
of samples analyzed.
    9.4 Analyzer Accuracy Test. Conduct the analyzer accuracy test by 
analyzing the accuracy assessment standard and comparing the value 
output by the measurement system with the ideal value for the accuracy 
assessment standard (see Figure 2). This analysis should be performed 
with each set of samples analyzed.

                  10.0 Calibration and Standardization.

    10.1 Perform the initial calibration and set-up following the 
instrument manufacturer's instructions. These procedures should include, 
at a minimum, the major steps listed in sections 10.2 and 10.3. 
Subsequent calibrations are to be performed when either a quality 
assurance/quality control (QA/QC) limit listed in section 13 is exceeded 
or when there is a change in the excitation conditions, such as a change 
in the tube, detector, X-ray filters, or signal processor. Calibrations 
are typically valid for 6 months to 1 year.
    10.2 Instrument Calibration. Calibration is performed initially with 
calibration standards of similar matrix and binders, if used, as the 
samples to be analyzed (see Figure 1).
    10.3 Reference Peak Spectra. Acquisition of reference spectra is 
required only during the initial calibration. As long as no processing 
methods have changed, these peak shape references remain valid. This 
procedure consists of placing the standards in the instrument and 
acquiring individual elemental spectra that are stored in the method 
file with each of the analytical conditions. These reference spectra are 
used in the standard deconvolution of the unknown spectra.

                       11.0 Analytical Procedure.

    11.1 Sample Preparation. Prepare catalyst samples using the same 
procedure used to prepare the calibration standards. Measure and record 
the weight of sample used. Measure and record the amount of binder, if 
any, used. Pellets or films must be of sufficient size to cover the 
analyzer sample window.
    11.2 Sample Analyses. Place the prepared catalyst samples into the 
analyzer. Follow the manufacturer's instructions for analyzing the 
samples.
    11.3 Record and Store Data. Use a digital recorder or personal 
computer to record and store results for each sample. Record any 
mechanical or software problems encountered during the analysis.

                  12.0 Data Analysis and Calculations.

    Carry out the following calculations, retaining at least one extra 
significant figure beyond that of the acquired data. Round off figures 
after final calculation.
    12.1 Drift. Calculate the zero and calibration drift for the tests 
described in sections 9.2 and 9.3 (see also Figure 2) as follows:

[GRAPHIC] [TIFF OMITTED] TR09FE05.010

Where:
CurrentAnalyzerCal.Response = Instrument response for current QC sample 
          analyses;
InitialCal.Response = Initial instrument response for calibration 
          standard;

[[Page 183]]

QC Value = QC metric (zero drift or calibration drift), percent of span;
Span = Span of the monitoring system.

    12.2 Analyzer Accuracy. Calculate the analyzer accuracy error for 
the tests described in section 9.4 (see also Figure 2) as follows:
[GRAPHIC] [TIFF OMITTED] TR09FE05.011

Where:

Accuracy Value = Percent difference of instrument response to the ideal 
          response for the accuracy assessment standard;
CurrentAnalyzerCal.Response = Instrument response for current QC sample 
          analyses;
IdealCal.Response = Ideal instrument response for the accuracy 
          assessment standard.

                        13.0 Method Performance.

    13.1 Analytical Range. The analytical range is determined by the 
instrument design. For this method, a portion of the analytical range is 
selected by choosing the span of the monitoring system. The span of the 
monitoring system must be selected such that it encompasses the range of 
concentrations anticipated to occur in the catalyst sample. If 
applicable, the span must be selected such that the analyte 
concentration equivalent to the emission standard is not less than 30 
percent of the span. If the measured analyte concentration exceeds the 
concentration of the high-range calibration standard, the sample 
analysis is considered invalid. Additionally, if the measured analyte 
concentration is less than the concentration of the low-range 
calibration standard but above the detectable limit, the sample analysis 
results must be flagged with a footnote stating, in effect, that the 
analyte was detected but that the reported concentration is below the 
lower quantitation limit.
    13.2 Minimum Detectable Limit. The minimum detectable limit depends 
on the signal-to-noise ratio of the measurement system. For a well-
designed system, the minimum detectable limit should be less than 2 
percent of the span.
    13.3 Zero Drift. Less than 2 percent of the 
span.
    13.4 Calibration Drift. Less than 5 percent of 
the span.
    13.5 Analyzer Accuracy Error. Less than 10 
percent.

program as defined by 40 CFR 403.8 (for a POTW owned or operated by a 
municipality, State, or intermunicipal or interstate agency), or your 
POTW would meet the general criteria for development and implementation 
of a pretreatment program (for a POTW owned or operated by a department, 
agency, or instrumentality of the Federal government).
    (b) If your existing POTW treatment plant is not located at a major 
source as of October 26, 1999, but thereafter becomes a major source for 
any reason other than reconstruction, then, for the purpose of this 
subpart, your POTW treatment plant would be considered an existing 
source. Note to Paragraph (b): See Sec. 63.2 of the national emission 
standards for hazardous air pollutants (NESHAP) General Provisions in 
subpart A of this part for the definitions of major source and area 
source.
    (c) If you reconstruct your POTW treatment plant, then the 
requirements for a new or reconstructed POTW treatment plant, as defined 
in Sec. 63.1595, apply.

[67 FR 64745, Oct. 21, 2002]



Sec. 63.1581  Does the subpart distinguish between different types
of POTW treatment plants?

    Yes, POTW treatment plants are divided into two subcategories. A 
POTW treatment plant which does not meet the characteristics of an 
industrial POTW treatment plant belongs in the non-industrial POTW 
treatment plant subcategory as defined in Sec. 63.1595.

      Industrial POTW Treatment Plant Description and Requirements



Sec. 63.1582  What are the characteristics of an industrial POTW 
treatment plant?

    (a) Your POTW is an industrial POTW treatment plant if an industrial 
discharger complies with its NESHAP by using the treatment and controls 
located at your POTW. Your POTW accepts the regulated waste stream and 
provides treatment and controls as an agent for the industrial 
discharger. Industrial POTW treatment plant is defined in Sec. 63.1595.
    (b) If, in the future, an industrial discharger begins complying 
with its NESHAP by using the treatment and controls at your POTW, then 
on the date that the industrial discharger certifies compliance, your 
POTW treatment plant will be considered an industrial POTW treatment 
plant.

[[Page 185]]

    (c) If your POTW treatment plant accepts one or more specific 
regulated industrial waste streams as part of compliance with one or 
more other NESHAP, then you are subject to all the requirements of each 
appropriate NESHAP for each waste stream, as described in the following 
section. In the case of overlapping NESHAP requirements, the more 
stringent of the requirements will apply.



Sec. 63.1583  What are the emission points and control requirements
for an industrial POTW treatment plant?

    (a) The emission points and control requirements for an existing 
industrial POTW treatment plant are specified in the appropriate 
NESHAP(s) for the industrial user(s) (see Sec. 63.1582). For example, 
an existing industrial POTW treatment plant that provides treatment for 
a facility subject to subpart FF of this part, the National Emission 
Standard for Benzene Waste Operations, must meet the treatment and 
control requirements specified in Sec. 61.348(d)(4) of this chapter.
    (b) The emission points and control requirements for a new or 
reconstructed industrial POTW treatment plant are either those specified 
by the particular NESHAP(s) which apply to the industrial user(s) who 
discharge their waste for treatment to the POTW, or those emission 
points and control requirements set forth in Sec. 63.1586. The set of 
control requirements which applies to a particular new or reconstructed 
POTW is that set which requires the most stringent overall control of 
HAP emissions. If you are uncertain which set of requirements is more 
stringent, this determination should be made in consultation with the 
permitting authority. Reconstruction is defined in Sec. 63.1595.



Sec. 63.1584  When do I have to comply?

    (a) Existing industrial POTW treatment plant. If you have an 
existing industrial POTW treatment plant, the appropriate NESHAP(s) for 
the industrial user(s) sets the compliance date, or the compliance date 
is 60 days after October 26, 1999, whichever is later.
    (b) New industrial POTW treatment plant. If you have a new 
industrial POTW treatment plant, you must be in compliance as soon as 
you begin accepting the waste stream(s) for treatment. If you begin 
accepting a specific regulated industrial waste stream(s) for treatment, 
you must be in compliance by the time specified in the appropriate 
NESHAP(s) for the industrial user(s).



Sec. 63.1585  How does an industrial POTW treatment plant demonstrate
compliance?

    (a) An existing industrial POTW treatment plant demonstrates 
compliance by operating treatment and control devices which meet all 
requirements specified in the appropriate industrial NESHAP(s). 
Requirements may include performance tests, routine monitoring, 
recordkeeping, and reporting.
    (b) If you have a new or reconstructed industrial POTW plant, you 
must first determine whether the control requirements set forth in the 
applicable industrial NESHAP(s) or the control requirements applicable 
to a new or reconstructed nonindustrial POTW under Sec. 63.1586 would 
require more stringent overall control of HAP emissions. You must then 
meet whichever set of requirements is more stringent. If you determine 
that the controls required by the applicable industrial NESHAP(s) are 
more stringent, you demonstrate compliance by operating treatment and 
control devices which meet all requirements specified in those 
industrial NESHAP(s). If you determine that the controls required for a 
new or reconstructed nonindustrial POTW are more stringent, you 
demonstrate compliance by meeting all requirements in Sec. Sec. 63.1586 
through 63.1590.

            Non-industrial POTW Treatment Plant Requirements



Sec. 63.1586  What are the emission points and control requirements
for a non-industrial POTW treatment plant?

    There are no control requirements for an existing non-industrial 
POTW treatment plant. There are no control requirements for any new or 
reconstructed area source non-industrial POTW treatment plant which is 
not a major source of HAP. The control requirements for a new or 
reconstructed

[[Page 186]]

major source non-industrial POTW treatment plant which is a major source 
of HAP are as follows:
    (a) Covers on the emission points up to, but not including, the 
secondary influent pumping station or the secondary treatment units. 
These emission points are treatment units that include, but are not 
limited to, influent waste stream conveyance channels, bar screens, grit 
chambers, grinders, pump stations, aerated feeder channels, primary 
clarifiers, primary effluent channels, and primary screening stations. 
In addition, all covered units, except primary clarifiers, must have the 
air in the headspace ducted to a control device in accordance with the 
standards for closed-vent systems and control devices in Sec. 63.693 of 
subpart DD of this part, except you may substitute visual inspections 
for leak checks rather than Method 21 of Appendix A of part 60 of this 
chapter. Reconstruction is defined in Sec. 63.1595.
    (1) Covers must be tightly fitted and designed and operated to 
minimize exposure of the wastewater to the atmosphere. This includes, 
but is not limited to, the absence of visible cracks, holes, or gaps in 
the roof sections or between the roof and the supporting wall; broken, 
cracked, or otherwise damaged seals or gaskets on closure devices; and 
broken or missing hatches, access covers, caps, or other closure 
devices.
    (2) If wastewater is in a treatment unit, each opening must be 
maintained in a closed, sealed position, unless plant personnel are 
present and conducting wastewater or sludge sampling, or equipment 
inspection, maintenance, or repair.
    (b) As an alternative to the requirements in paragraph (a) of this 
section, you may comply by demonstrating, for all units up to the 
secondary influent pumping station or the secondary treatment units, 
that the fraction emitted does not exceed 0.014. You must demonstrate 
that for your POTW, the sum of all HAP emissions from those units 
divided by the sum of all HAP mass loadings results in an annual rolling 
average of the fraction emitted no greater than 0.014. You may use any 
combination of pretreatment, wastewater treatment plant modifications, 
and control devices to achieve this performance standard; however, you 
must demonstrate, to the Administrator's satisfaction that:
    (1) You have accurately determined your POTW's annual HAP mass 
loadings and your POTW's annual HAP emissions as of the date of start-
up;
    (2) Your POTW meets the fraction emitted standard of 0.014 or less; 
and
    (3) Your POTW has established procedures to demonstrate continuous 
compliance which are consistent with the criteria set forth in Sec. 
63.1588(c)(4).

[64 FR 57579, Oct. 26, 1999, as amended at 66 FR 16142, Mar. 23, 2001; 
67 FR 64746, Oct. 21, 2002]



Sec. 63.1587  When do I have to comply?

    If your POTW treatment plant began construction on or after December 
1, 1998, you must comply with all provisions of this subpart either 
immediately upon startup, or by six months after October 26, 1999, 
whichever date is later.



Sec. 63.1588  What inspections must I conduct?

    (a) If your treatment units are required to have covers, you must 
conduct the following inspections:
    (1) You must visually check the cover and its closure devices for 
defects that could result in air emissions. Defects include, but are not 
limited to, visible cracks, holes, or gaps in the roof sections or 
between the roof and the supporting wall; broken, cracked, or otherwise 
damaged seals or gaskets on closure devices; and broken or missing 
hatches, access covers, caps, or other closure devices.
    (2) You must perform an initial visual inspection with follow-up 
inspections at least once per year.
    (3) In the event that you find a defect on a treatment unit in use, 
you must repair the defect within 45 days. If you cannot repair within 
45 days, you must notify the EPA or the designated State authority 
immediately and report the reason for the delay and the date you expect 
to complete the repair. If you find a defect on a treatment unit that is 
not in service, you must repair the defect prior to putting the 
treatment unit back in wastewater service.
    (b) If you own or operate a control device used to meet the 
requirements

[[Page 187]]

for Sec. 63.1586, you must comply with the inspection and monitoring 
requirements of Sec. 63.695(c) of subpart DD of this part.
    (c) To comply with the performance standard specified in Sec. 
63.1586(b), you must develop an inspection and monitoring plan. This 
inspection and monitoring plan must include, at a minimum, the 
following:
    (1) A method to determine, to the satisfaction of the Administrator, 
the influent HAP mass loading, i.e., the annual mass quantity for each 
HAP entering the wastewater treatment plant.
    (2) A method to determine, to the satisfaction of the Administrator, 
your POTW's annual HAP emissions for all units up to and including the 
secondary influent pumping station or up to and not including the 
secondary treatment units as of October 26, 1999. The method you use to 
determine your HAP emissions, such as modeling or direct source 
measurement, must:
    (i) Be approved by your EPA Regional Office, State, or local 
regulatory agency for use at your POTW;
    (ii) Account for all factors affecting emissions from your plant 
including, but not limited to, emissions from wastewater treatment 
units; emissions resulting from inspection, maintenance, and repair 
activities; fluctuations (e.g., daily, monthly, annual, seasonal) in 
your influent wastewater HAP concentrations; annual industrial loading; 
performance of control devices; or any other factors that could affect 
your annual HAP emissions; and
    (iii) Include documentation that the values and sources of all data, 
operating conditions, assumptions, etc., used in your method result in 
an accurate estimation of annual emissions from your plant.
    (3) Documentation, to the satisfaction of the Administrator, that 
your POTW meets the fraction emitted standard of 0.014 or less, i.e., 
the sum of all HAP emissions from paragraph (c)(2) of this section 
divided by the sum of all HAP mass loadings from paragraph (c)(1) of 
this section results in a fraction emitted of 0.014 or less as described 
in paragraph (c)(4) of this section.
    (4) A method to demonstrate, to the satisfaction of the 
Administrator, that your POTW is in continuous compliance with the 
requirements of Sec. 63.1586(b). Continuous compliance means that your 
emissions, when averaged over the course of a year, do not exceed the 
level of emissions that allows your POTW to comply with Sec. 
63.1586(b). For example, you may identify a parameter(s) that you can 
monitor that assures your emissions, when averaged over the entire year, 
will meet the requirements in Sec. 63.1586(b). Some example parameters 
that may be considered for monitoring include your wastewater influent 
HAP concentration and flow, industrial loading from your permitted 
industrial dischargers, and your control device performance criteria. 
Where emission reductions are due to proper operation of equipment, work 
practices, or other operational procedures, your demonstration must 
specify the frequency of inspections and the number of days to 
completion of repairs. You must, at a minimum, perform the following 
each month to demonstrate that your annual rolling average of the 
fraction emitted is 0.014 or less:
    (i) Determine the average daily flow of the wastewater entering your 
POTW treatment plant for the month;
    (ii) Determine the flow-weighted monthly concentration of each HAP 
in your influent listed in Table 1 to subpart DD of this part;
    (iii) Using the current month's information in paragraphs (c)(4)(i) 
and (ii) of this section, determine a total annual loading (Mg/year) of 
each HAP entering your POTW treatment plant;
    (iv) Sum up the values in paragraph (c)(4)(iii) of this section and 
determine a total annual loading value (Mg/year) for all HAP entering 
your POTW treatment plant for the current month;
    (v) Based on the current month's information in paragraph 
(c)(4)(iii) of this section along with source testing and emission 
modeling, for each HAP, determine annual emissions (Mg/year) from all 
wastewater units up to, but not including, secondary treatment units;
    (vi) Sum up the values in paragraph (c)(4)(v) of this section and 
determine the total annual emissions value for

[[Page 188]]

the month for all HAP from all wastewater units up to, but not 
including, secondary treatment units;
    (vii) Calculate the fraction emitted value for the month by dividing 
the total annual HAP emissions value from paragraph (c)(4)(vi) of this 
section by the total annual loading from paragraph (c)(4)(iv) of this 
section; and
    (viii) Average the fraction emitted value for the month determined 
in paragraph (c)(4)(vii) of this section, with the values determined for 
the previous 11 months, to calculate an annual rolling average of the 
fraction HAP emitted.



Sec. 63.1589  What records must I keep?

    (a) To comply with the equipment standard specified in Sec. 
63.1586(a), you must prepare and maintain the records required in 
paragraphs (a)(1) through (4) of this section:

63.1588(a). You must include a treatment unit identification number (or 
other unique identification description as selected by you) and the date 
of inspection.
    (2) For each defect detected during inspections required by Sec. 
63.1588(a), you must record the location of the defect, a description of 
the defect, the date of detection, the corrective action taken to repair 
the defect, and the date the repair to correct the defect is completed.
    (3) In the event that repair of the defect is delayed, in accordance 
with the provisions of Sec. 63.1588(a)(3), you must also record the 
reason for the delay and the date you expect to complete the repair.
    (4) If you own or operate a control device used to meet the 
requirements for Sec. 63.1586, you must comply with the recordkeeping 
requirements of Sec. 63.696(a), (b), (g), and (h).
    (b) To comply with the performance standard specified in Sec. 
63.1586(b), you must prepare and maintain the records required in 
paragraphs (b)(1) through (3) of this section:
    (1) A record of the methods and data used to determine your POTW's 
annual HAP emissions as determined in Sec. 63.1588(c)(2);
    (2) A record of the methods and data used to determine that your 
POTW meets the fraction emitted standard of 0.014 or less, as determined 
in Sec. 63.1588(c)(3); and
    (3) A record of the methods and data that demonstrates that your 
POTW is in continuous compliance with the requirements of Sec. 
63.1588(c)(4).

[68 FR 37360, June 23, 2003]



Sec. 63.1595  List of definitions.

    Affected source means the group of all equipment that comprise the 
POTW treatment plant.
    Area source means any stationary source of HAP that is not a major 
source.
    Cover means a device that prevents or reduces air pollutant 
emissions to the atmosphere by forming a continuous barrier over the 
waste material managed in a treatment unit. A cover may have openings 
(such as access hatches, sampling ports, gauge wells) that are necessary 
for operation, inspection, maintenance, and repair of the treatment unit 
on which the cover is used. A cover may be a separate piece of equipment 
which can be detached and removed from the treatment unit, or a cover 
may be formed by structural features permanently integrated into the 
design of the treatment unit. The cover and its closure devices must be 
made of suitable materials that will minimize exposure of the waste 
material to the atmosphere, to the extent practical, and will maintain 
the integrity of the cover and its closure devices throughout its 
intended service life.
    Fraction emitted means the fraction of the mass of HAP entering the 
POTW wastewater treatment plant which is emitted prior to secondary 
treatment. The value is calculated using the following steps:
    (1) Determine mass emissions from all equipment up to, but not 
including, secondary treatment for each HAP listed in Table 1 to subpart 
DD of this part;
    (2) Sum the HAP emissions ([Sigma]E);
    (3) Sum the HAP mass loadings ([Sigma]L) in the influent to the POTW 
wastewater treatment plant; and
    (4) Calculate the fraction emitted (fe monthly) using 
fe monthly = [Sigma]E/[Sigma]L.
    HAP means hazardous air pollutant(s).
    Industrial POTW means a POTW that accepts a waste stream regulated 
by an industrial NESHAP and provides treatment and controls as an agent 
for the industrial discharger. The industrial discharger complies with 
its NESHAP by using the treatment and controls located at the POTW. For 
example, an industry discharges its benzene-containing waste stream to 
the POTW for treatment to comply with 40 CFR part 61, Subpart FF--
National Emission Standard for Benzene Waste Operations. This definition 
does not include POTW treating waste streams not specifically regulated 
under another NESHAP.
    Industrial user means a nondomestic source introducing any pollutant 
or combination of pollutants into a POTW. Industrial users can be 
commercial or industrial facilities whose wastes enter local sewers.
    Non-industrial POTW means a POTW that does not meet the definition 
of an industrial POTW as defined above.
    Publicly owned treatment works (POTW) means a treatment works, as 
that term is defined by section 112(e)(5) of the Clean Air Act, which is 
owned by

[[Page 191]]

a municipality (as defined by section 502(4) of the Clean Water Act), a 
State, an intermunicipal or interstate agency, or any department, 
agency, or instrumentality of the Federal Government. This definition 
includes any intercepting sewers, outfall sewers, sewage collection 
systems, pumping, power, and other equipment. The wastewater treated by 
these facilities is generated by industrial, commercial, and domestic 
sources. As used in this regulation, the term POTW refers to both any 
publicly owned treatment works which is owned by a State, municipality, 
or intermunicipal or interstate agency and therefore eligible to receive 
grant assistance under the Subchapter II of the Clean Water Act, and any 
federally owned treatment works as that term is described in section 
3023 of the Solid Waste Disposal Act.
    POTW treatment plant means that portion of the POTW which is 
designed to provide treatment (including recycling and reclamation) of 
municipal sewage and industrial waste.
    Reconstruction means the replacement of components of an affected or 
a previously unaffected stationary source such that:
    (1) The fixed capital cost of the new components exceeds 50 percent 
of the fixed capital cost that would be required to construct a 
comparable new source; and
    (2) It is technologically and economically feasible for the 
reconstructed source to meet the relevant standard(s) established by the 
Administrator (or a State) pursuant to section 112 of the Act. Upon 
reconstruction, an affected source, or a stationary source that becomes 
an affected source, is subject to relevant standards for new sources, 
including compliance dates, irrespective of any change in emissions of 
HAP from that source.
    Secondary treatment means treatment processes, typically biological, 
designed to reduce the concentrations of dissolved and colloidal organic 
matter in wastewater.
    Waste and wastewater means a material, or spent or used water or 
waste, generated from residential, industrial, commercial, mining, or

Sec. 63.1622  What definitions apply to this subpart?

    Terms in this subpart are defined in the Clean Air Act (Act), in 
subpart A of this part, or in this section as follows:
    Bag leak detection system means a system that is capable of 
continuously monitoring particulate matter (dust) loadings in the 
exhaust of a baghouse in order to detect bag leaks and other upset 
conditions. A bag leak detection system includes, but is not limited to, 
an instrument that operates on triboelectric, light scattering, light 
transmittance, or other effect to continuously monitor relative 
particulate matter loadings.
    Capture system means the collection of components used to capture 
the gases and fumes released from one or more emissions points and then 
convey the captured gas stream to a control device or to the atmosphere. 
A capture system may include, but is not limited to, the following 
components as applicable to a given capture system design: Duct intake 
devices, hoods, enclosures, ductwork, dampers, manifolds, plenums, fans 
and roofline ventilation systems.
    Casting means the period of time from when molten ferroalloy is 
removed from the tapping station until the pouring into casting molds or 
beds is completed. This includes the following operations: Pouring alloy 
from one ladle to another, slag separation, slag removal and ladle 
transfer by crane, truck, or other conveyance.
    Crushing and screening equipment means the crushers, grinders, 
mills, screens and conveying systems used to crush, size and prepare for 
packing manganese-containing materials, including raw materials, 
intermediate products and final products.
    Electric arc furnace means any furnace where electrical energy is 
converted to heat energy by transmission of current between electrodes 
partially submerged in the furnace charge. The furnace may be of an 
open, semi-sealed, or sealed design.
    Furnace process cycle means the period in which the furnace is 
tapped to the time in which the furnace is tapped again and includes 
periods of charging, smelting, tapping, casting and ladle raking. For 
multiple furnaces operating within a single shop building, furnace 
process cycle means a period sufficient to capture a full cycle of 
charging, smelting, tapping, casting and ladle raking for each furnace 
within the shop building.

[[Page 195]]

    Ladle treatment means a post-tapping process including metal and 
alloy additions where chemistry adjustments are made in the ladle after 
furnace smelting to achieve a specified product.
    Local ventilation means hoods, ductwork, and fans designed to 
capture process fugitive emissions close to the area where the emissions 
are generated (e.g., tap hoods).
    Metal oxygen refining (MOR) process means the reduction of the 
carbon content of ferromanganese through the use of oxygen.
    Outdoor fugitive dust source means a stationary source from which 
hazardous air pollutant-bearing particles are discharged to the 
atmosphere due to wind or mechanical inducement such as vehicle traffic. 
Fugitive dust sources include plant roadways, yard areas and outdoor 
material storage and transfer operation areas.
    Plant roadway means any area at a ferromanganese and silicomanganese 
production facility that is subject to plant mobile equipment, such as 
forklifts, front end loaders, or trucks, carrying manganese-bearing 
materials. Excluded from this definition are employee and visitor 
parking areas, provided they are not subject to traffic by plant mobile 
equipment.
    Process fugitive emissions source means a source of hazardous air 
pollutant emissions that is associated with a ferromanganese or 
silicomanganese production facility and is not a fugitive dust source or 
a stack emissions source. Process fugitive sources include emissions 
that escape capture from the electric arc furnace, tapping operations, 
casting operations, ladle treatment, MOR or crushing and screening 
equipment.

plan that documents the equipment and operations designed to effectively 
capture process fugitive emissions. The plan will be deemed to achieve 
effective capture if it consists of the following elements:
    (i) Documentation of engineered hoods and secondary fugitive capture 
systems designed according to the most recent, at the time of 
construction, ventilation design principles recommended by the American 
Conference of Governmental Industrial Hygienists (ACGIH). The process 
fugitive emissions capture systems must be designed to achieve 
sufficient air changes to evacuate the collection area frequently enough 
to ensure process fugitive emissions are effectively collected by the 
ventilation system and ducted to the control device(s). The required 
ventilation systems should also use properly positioned hooding to take 
advantage of the inherent air flows of the source and capture systems 
that minimize air flows while also intercepting natural air flows or 
creating air flows to contain the fugitive emissions. Include a 
schematic for each building indicating duct sizes and locations, hood 
sizes and locations, control device types, size and locations and 
exhaust locations. The design plan must identify the key operating 
parameters and measurement locations to ensure proper operation of the 
system and establish monitoring parameter values that reflect effective 
capture.
    (ii) List of critical maintenance actions and the schedule to 
conduct them.
    (2) You must submit a copy of the process fugitive emissions 
ventilation plan to the designated permitting authority on or before the 
applicable compliance date for the affected source as specified in Sec. 
63.1621 in electronic format and whenever an update is made to the plan. 
The requirement for you to operate the facility according to the written 
process fugitives ventilation plan and specifications must be 
incorporated in the operating permit for the facility that is issued by 
the designated permitting authority under part 70 or 71 of this chapter, 
as applicable.
    (3) You must update the information required in paragraphs (a)(1) 
and (2) of this section every 5 years or whenever there is a significant 
change in variables that affect process fugitives ventilation design 
such as the addition of a new process.
    (b) Outdoor fugitive dust sources. (1) You must prepare, and at all 
times operate according to, an outdoor fugitive dust control plan that 
describes in detail the measures that will be put in place to control 
outdoor fugitive dust emissions from the individual fugitive dust 
sources at the facility.
    (2) You must submit a copy of the outdoor fugitive dust control plan 
to the designated permitting authority on or before the applicable 
compliance date for the affected source as specified in Sec. 63.1621. 
The requirement for you to operate the facility according to a written 
outdoor fugitive dust control plan must be incorporated in the operating 
permit for the facility that is

[[Page 198]]

issued by the designated permitting authority under part 70 or 71 of 
this chapter, as applicable.
    (3) You may use existing manuals that describe the measures in place 
to control outdoor fugitive dust sources required as part of a state 
implementation plan or other federally enforceable requirement for 
particulate matter to satisfy the requirements of paragraph (b)(1) of 
this section.

collect less than 4.0 cubic meters per run provided that the filterable 
mass collected (i.e., net filter mass plus mass of nozzle, probe and 
filter holder rinses) is equal to or greater than 10 mg. If the total 
mass collected for two of three of the runs is less than 10 mg, you must 
conduct at least one additional test run that produces at least 10 mg of

PAH compliance testing cannot be reduced to less than once per year.
    (v) You must conduct ongoing performance tests every 5 years for air 
pollution control devices or vent stacks subject to Sec. 63.1623(a)(4), 
(a)(5), (b)(1), and (c) through (e) to demonstrate compliance with the 
applicable emission standards.

[[Page 200]]

    (3) Compliance is demonstrated for all sources performing emissions 
tests if the average concentration for the three runs comprising the 
performance test does not exceed the standard.
    (4) Operating limits. You must establish parameter operating limits 
according to paragraphs (c)(4)(i) through (iv) of this section. Unless 
otherwise specified, compliance with each established operating limit 
shall be demonstrated for each 24-hour operating day.
    (i) For a wet particulate matter scrubber, you must establish the 
minimum liquid flow rate and pressure drop as your operating limits 
during the three-run performance test. If you use a wet particulate 
matter scrubber and you conduct separate performance tests for 
particulate matter, you must establish one set of minimum liquid flow 
rate and pressure drop operating limits. If you conduct multiple 
performance tests, you must set the minimum liquid flow rate and 
pressure drop operating limits at the highest minimum hourly average 
values established during the performance tests.

    (iv) If you choose to demonstrate continuous compliance through a 
particulate matter CEMS, you must determine an operating limit 
(particulate matter concentration in mg/dscm) during performance testing 
for initial particulate matter compliance. The operating limit will be 
the average of the PM filterable results of the three Method 5 or Method 
5D of appendix A-3 of 40 CFR part 60 performance test runs. To determine 
continuous compliance, the hourly average PM concentrations will be 
averaged on a rolling 30 operating day basis. Each 30 operating day 
average will have to meet the PM operating limit.
    (d) Compliance demonstration with shop building opacity standards. 
(1)(i) If you are subject to Sec. 63.1623(b), you must conduct opacity 
observations of the shop building to demonstrate compliance with the 
applicable opacity standards according to Sec. 63.6(h)(5), which 
addresses conducting opacity or visible emission observations.

    (vi) You may reduce the frequency of observations to once per month 
for each shop building that demonstrates compliance with the weekly 8-
percent opacity limit for 26 consecutive complete observations that span 
a period of at least 26 weeks. Any monthly observation in excess of 8-
percent opacity will return that shop building opacity observation to a 
weekly compliance schedule. You may reduce the frequency of observations 
again to once per month for each shop building that demonstrates 
compliance with the weekly 8-percent opacity limit after

[[Page 201]]

another 26 consecutive complete observations that span a period of at 
least 26 weeks.
    (2) You must determine shop building opacity operating parameters 
based on either monitoring data collected during the compliance 
demonstration or established in an engineering assessment.
    (i) If you choose to establish parameters based on the initial 
compliance demonstration, you must simultaneously monitor parameter 
values for one of the following: The capture system fan motor amperes 
and all capture system damper positions, the total volumetric flow rate 
to the air pollution control device and all capture system damper 
positions, or volumetric flow rate through each separately ducted hood 
that comprises the capture system. Subsequently you must monitor these 
parameters according to Sec. 63.1626(g) and ensure they remain within 
10 percent of the value recorded during the compliant opacity readings.
    (ii) If you choose to establish parameters based on an engineering 
assessment, then a design analysis shall include, for example, 
specifications, drawings, schematics and ventilation system diagrams 
prepared by the owner or operator or capture or control system 
manufacturer or vendor that describes the shop building opacity system 
ventilation design based on acceptable engineering texts. The design 
analysis shall address vent stream characteristics and ventilation 
system design operating parameters such as fan amps, damper position, 
flow rate and/or other specified parameters.
    (iii) You may petition the Administrator to reestablish these 
parameter ranges whenever you can demonstrate to the Administrator's 
satisfaction that the electric arc furnace or MOR operating conditions 
upon which the parameter ranges were previously established are no 
longer applicable. The values of these parameter ranges determined 
during the most recent demonstration of compliance must be maintained at 
the appropriate level for each applicable period.
    (3) You will demonstrate continuing compliance with the opacity 
standards by following the monitoring requirements specified in Sec. 
63.1626(g) and the reporting and recordkeeping requirements specified in 
Sec. 63.1628(b)(5).
    (e) Compliance demonstration with the operational and work practice 
standards--(1) Process fugitive emissions sources. You will demonstrate 
compliance by developing and maintaining a process fugitives ventilation 
plan, by reporting any deviations from the plan and by taking necessary 
corrective actions to correct deviations or deficiencies.
    (2) Outdoor fugitive dust sources. You will demonstrate compliance 
by developing and maintaining an outdoor fugitive dust control plan, by 
reporting any deviations from the plan and by taking necessary 
corrective actions to correct deviations or deficiencies.
    (3) Baghouses equipped with bag leak detection systems. You will 
demonstrate compliance with the bag leak detection system requirements 
by developing an analysis and supporting documentation demonstrating 
conformance with EPA guidance and specifications for bag leak detection 
systems in Sec. 60.57c(h) of this chapter.

the need to initiate corrective action as soon as

[[Page 204]]

practicable after the monitoring excursion in order to minimize excess 
emissions.
    (h) Furnace capture system. You must perform quarterly (once every 
three months) inspections of the furnace fugitive capture system 
equipment to ensure that the hood locations have not been changed or 
obstructed because of contact with cranes or ladles, quarterly 
inspections of the physical condition of hoods and ductwork to the 
control device to determine if there are any openings or leaks in the 
ductwork, quarterly inspections of the hoods and ductwork to determine

flow rate controllers (pressure sensors, dampers, damper switches, etc.) 
to ensure they are operating correctly. Any deficiencies must be 
recorded and proper maintenance and repairs performed.
    (i) Requirements for sources using CMS. If you demonstrate 
compliance with any applicable emissions limit through use of a 
continuous monitoring system (CMS), where a CMS includes a continuous 
parameter monitoring system (CPMS) as well as a continuous emissions 
monitoring system (CEMS), you must develop a site-specific monitoring 
plan and submit this site-specific monitoring plan, if requested, at 
least 60 days before your initial performance evaluation (where 
applicable) of your CMS. Your site-specific monitoring plan must address 
the monitoring system design, data collection and the quality assurance 
and quality control elements outlined in this paragraph and in Sec. 
63.8(d). You must install, operate and maintain each CMS according to 
the procedures in your approved site-specific monitoring plan. Using the 
process described in Sec. 63.8(f)(4), you may request approval of 
monitoring system quality assurance and quality control procedures 
alternative to those specified in paragraphs (i)(1) through (6) of this 
section in your site-specific monitoring plan.

each successive 15-minute period. You must have a minimum of four 
successive cycles of operation to have a valid hour of data.
    (2) Except for periods of monitoring system malfunctions, repairs 
associated with monitoring system malfunctions and required monitoring 
system quality assurance or quality control activities (including, as 
applicable, system accuracy audits and required zero and span 
adjustments), you must operate the CMS at all times the affected source 
is operating. A monitoring system malfunction is any sudden, infrequent, 
not reasonably preventable failure of the monitoring system to provide 
valid data. Monitoring system failures that are caused in part by poor 
maintenance or careless operation are not malfunctions. You are required 
to complete monitoring system repairs in response to monitoring system 
malfunctions and to return the monitoring system to operation as 
expeditiously as practicable.

for the Administrator's inspection for the life of the air pollution 
control device or until the affected source is no longer subject to the 
provisions of this part.
    (2) To satisfy the requirement to develop maintenance plans, the 
owner or operator may use the affected source's standard operating 
procedures (SOP) manual or other plan, provided the alternative plan 
meets the requirements of this paragraph and is made available for 
inspection when requested by the Administrator.

    (7) Method 9 of appendix A-4 of 40 CFR part 60 to determine opacity. 
ASTM D7520-13, ``Standard Test Method for Determining the Opacity of a 
Plume in the Outdoor Ambient Atmosphere'' may be used (incorporated by 
reference, see Sec. 63.14) with the following conditions:
    (i) During the digital camera opacity technique (DCOT) certification 
procedure outlined in Section 9.2 of ASTM D7520-13, the owner or

backgrounds of color and contrast representing conditions anticipated 
during field use such as blue sky, trees and mixed backgrounds (clouds 
and/or a sparse tree stand).
    (ii) The owner or operator must also have standard operating 
procedures in place including daily or other frequency quality checks to 
ensure the equipment is within manufacturing specifications as outlined 
in Section 8.1 of ASTM D7520-13.
    (iii) The owner or operator must follow the recordkeeping procedures 
outlined in Sec. 63.10(b)(1) for the DCOT certification, compliance

these requirements is on the facility, DCOT operator and DCOT vendor.
    (8) The owner or operator may use equivalent alternative measurement 
methods approved by the Administrator following the procedures described 
in Sec. 63.7(f) of subpart A.
    (c) Compliance demonstration with the emission standards. (1) The

[[Page 214]]

compliance with the applicable emission standards.
    (2) The owner or operator must conduct annual performance tests for 
the air pollution control devices and vent stacks associated with the 
submerged arc furnaces, with the exception of any air pollution control 
devices that serve tapping emissions combined with non-furnace 
emissions, such as the MOR process or equipment associated with crushing 
and screening. Also excluded are air pollution control devices that 
serve dedicated non-furnace emissions, such as the MOR process or 
equipment associated with crushing and screening. The results of these 
annual tests will be used to demonstrate compliance with the emission 
standards in Sec. 63.1652(a) through (e), as applicable.
    (3) Following development, and approval, if required, of the site-
specific test plan, the owner or operator must conduct a performance 
test for each air pollution control device or vent stack to measure 
particulate matter and determine compliance with the applicable 
standard.
    (i) An owner or operator of sources subject to the particulate 
matter concentration standards in Sec. 63.1652(a)(2), (d), or (e), must 
determine compliance as follows:
    (A) Determine the particulate matter concentration using Method 5 or 
5D, as applicable.
    (B) Compliance is demonstrated if the average concentration for the 
three runs comprising the performance test does not exceed the standard.
    (ii) An owner or operator of sources subject to the particulate mass 
rate standards in Sec. 63.1652(b) or (c) must determine compliance as 
follows:
    (A) Determine the particulate matter concentration and volumetric 
flow rate using Method 5 or 5D, as applicable.
    (B) Compute the mass rate (EM) of particulate matter for 
each run using the following equation:
[GRAPHIC] [TIFF OMITTED] TR20MY99.000

          stream ``i'', dscm/hr (dscf/hr)
K = conversion factor, 1 x 10\6\ mg/kg (7,000 gr/lb).

    (C) Compliance is demonstrated if the average of the mass rates for 
the three runs comprising the performance test does not exceed the 
standard.
    (iii) An owner or operator of sources subject to the particulate 
matter process-weighted rate standard in Sec. 63.1652(a)(1) must 
determine compliance as follows:
    (A) Determine particulate matter concentration and volumetric flow 
rate using Method 5 or 5D, as applicable.
    (B) Compute the process-weighted mass rate (EP) of 
particulate matter for each run using the following equation:
[GRAPHIC] [TIFF OMITTED] TR20MY99.001

Where:

          stream ``i'', dscm/hr (dscf/hr)
P = Average furnace power input, MW
K = conversion factor, 1 x 10\6\ mg/kg (7,000 gr/lb).

    (C) Compliance is demonstrated if the average process-weighted mass 
rate for the three runs comprising the performance test does not exceed 
the standard.
    (4) If a venturi scrubber is used to comply with the emission 
standards, the owner or operator must establish as a site-specific 
operating parameter the lowest average pressure drop on any individual 
complying run in the three runs constituting any compliant test. The 
pressure drop must be monitored at least every 5 minutes during the test

    (i) [Reserved]

[[Page 215]]

    (ii) The owner or operator may augment the data obtained under 
paragraph (a)(4) of this section by conducting multiple performance 
tests to establish a range of compliant operating parameter values. The 
lowest value of this range would be selected as the operating parameter 
monitoring value. The use of historic compliance data may be used to 
establish the compliant operating parameter value if the previous values 
were recorded during performance tests using the same test methods 
specified in this subpart and established as required in paragraph 
(a)(4) of this section.
    (d) Compliance demonstration with opacity standards. (1)(i) The 
owner or operator subject to Sec. 63.1653 must conduct initial opacity

owner or operator must simultaneously establish parameter values for one 
of the following: the control system fan motor amperes and all capture 
system damper positions, the total volumetric flow rate to the air 
pollution control device and all capture system damper positions, or 
volumetric flow rate through each separately ducted hood that comprises 
the capture system.
    (ii) The owner or operator may petition the Administrator to 
reestablish these parameters whenever he or she can demonstrate to the 
Administrator's satisfaction that the submerged arc furnace operating 
conditions upon which the parameters were previously established are no 
longer applicable. The values of these parameters determined during the 
most recent demonstration of compliance must be maintained at the 
appropriate level for each applicable period.
    (3) The owner or operator must demonstrate continuing compliance 
with the opacity standards by following the monitoring requirements 
specified in Sec. 63.1657(c) and the reporting and recordkeeping 
requirements specified in Sec. Sec. 63.1659(b)(4) and 63.1660(b).
    (e) Compliance demonstration with the operational and work practice 
standards--(1) Fugitive dust sources. Failure to have a fugitive dust 
control plan or failure to report deviations from the plan and take 
necessary corrective action would be a violation of the general duty to 
ensure that fugitive dust sources are operated and maintained in a 
manner consistent with good air pollution control practices for 
minimizing emissions per Sec. 63.1652(f).
    (2) Baghouses equipped with bag leak detection systems. The owner or

requirements by submitting reports as required by Sec. 63.1659(b)(5) 
showing that the alarm on the system does not sound for more than 5 
percent of the total operating time in a 6-month period. Calculate the 
percentage of total operating time the alarm on the bag leak detection 
system sounds as follows:
    (i) Do not include alarms that occur due solely to a malfunction of 
the bag leak detection system in the calculation.
    (ii) [Reserved]
    (iii) Count 1 hour of alarm time for each alarm where the owner or 
operator initiates procedures to determine the cause within 1 hour of 
the alarm.
    (iv) Count the actual time it takes the owner or operator to 
initiate procedures to determine the cause of the alarm for each alarm 
where the owner or operator does not initiate procedures to determine 
the cause within 1 hour of the alarm.
    (v) Calculate the percentage of time the alarm on the bag leak 
detection system sounds as the ratio of the sum

[[Page 216]]

    (a) Baghouses. (1) For the baghouses serving the submerged arc 
furnaces, the metal oxygen refining process, and crushing and screening 
operations, the owner or operator must observe on a daily basis for the 
presence of any visible emissions.
    (2) In addition to the daily visible emissions observation, the 
owner or operator must conduct the following activities:
    (i) Daily monitoring of pressure drop across each baghouse cell, or 
across the baghouse if it is not possible to monitor each cell 
individually, to ensure the pressure drop is within the normal operating 
range identified in the baghouse maintenance plan.
    (ii) Weekly confirmation that dust is being removed from hoppers 
through visual inspection, or equivalent means of ensuring the proper 
functioning of removal mechanisms.
    (iii) Daily check of compressed air supply for pulse-jet baghouses.
    (iv) An appropriate methodology for monitoring cleaning cycles to 
ensure proper operation.
    (v) Monthly check of bag cleaning mechanisms for proper functioning 
through visual inspection or equivalent means.
    (vi) Quarterly visual check of bag tension on reverse air and 
shaker-type baghouses to ensure that the bags are not kinked (kneed or 
bent) or laying on their sides. Such checks are not required for shaker-
type baghouses using self-tensioning (spring loaded) devices.
    (vii) Quarterly confirmation of the physical integrity of the 
baghouse structure through visual inspection of the baghouse interior 
for air leaks.
    (viii) Semiannual inspection of fans for wear, material buildup, and 
corrosion through visual inspection, vibration detectors, or equivalent 
means.
    (3) In addition to meeting the requirements of paragraphs (a)(1) and 
(a)(2) of this section, the owner or operator of a new or reconstructed 
submerged arc furnace must install and continuously operate a bag leak 
detection system if the furnace primary and/or tapping emissions are 
ducted to a negative pressure baghouse or to a positive pressure 
baghouse equipped with a stack. The bag leak detection system must meet 
the following requirements:
    (i) The bag leak detection system must be certified by the 
manufacturer to be capable of detecting particulate matter emissions at 
concentrations of 10 milligrams per actual cubic meter (0.0044 grains 
per actual cubic foot) or less.
    (ii) The bag leak detection system sensor must provide output of 
relative particulate matter loadings, and the owner or operator must 
continuously record the output from the bag leak detection system.
    (iii) The bag leak detection system must be equipped with an alarm 
system that will sound when an increase in relative particulate loadings 
is detected over a preset level. The alarm must be located where it can 
be heard by the appropriate plant personnel.
    (iv) Each bag leak detection system that works based on the 
triboelectric effect must be installed, calibrated, operated, and 
maintained consistent with the U.S. Environmental Protection Agency 
guidance document ``Fabric Filter Bag Leak Detection Guidance'' (EPA-
454/R-98-015). Other bag leak detection systems must be installed, 
calibrated, and maintained consistent with the manufacturer's written 
specifications and recommendations.
    (v) The initial adjustment of the system must, at a minimum, consist 
of establishing the baseline output by adjusting the sensitivity (range) 
and the averaging period of the device, and establishing the alarm set 
points and the alarm delay time.
    (vi) Following initial adjustment, the owner or operator must not 
adjust the sensitivity or range, averaging period, alarm set points, or 
alarm delay time, except as detailed in the maintenance plan required 
under Sec. 63.1655(b). In no event must the sensitivity be increased by 
more than 100 percent or decreased more than 50 percent over a 365-day 
period unless a responsible official certifies the baghouse has been 
inspected

[[Page 217]]

and found to be in good operating condition.
    (vii) Where multiple detectors are required, the system's 
instrumentation and alarm may be shared among detectors.
    (4) As part of the maintenance plan required by Sec. 63.1655(b), 
the owner or operator must develop and implement corrective action 
procedures to be followed in the case of a bag leak detection system 
alarm (for baghouses equipped with such a system), the observation of 
visible emissions from the baghouse, or the indication through the 
periodic baghouse system inspections that the system is not operating 
properly. The owner or operator must initiate corrective action as soon 
as practicable after the occurrence of the observation or event 
indicating a problem.
    (5) The corrective action plan must include procedures used to 
determine the cause of an alarm or other indications of problems as well 
as actions to minimize emissions. These actions may include the 
following:
    (i) Inspecting the baghouse for air leaks, torn or broken bags or 
filter media, or any other condition that may cause an increase in 
emissions.
    (ii) Sealing off defective bags or filter media.
    (iii) Replacing defective bags or filter media, or otherwise 
repairing the control device.
    (iv) Sealing off a defective baghouse compartment.
    (v) Cleaning the bag leak detection system probe, or otherwise 
repairing the bag leak detection system.
    (vi) Shutting down the process producing the particulate matter 
emissions.
    (6) Failure to monitor or failure to take corrective action under 
the requirements of paragraph (a) of this section would be a violation 
of the general duty to operate in a manner consistent with good air 
pollution control practices that minimizes emissions per Sec. 
63.1652(f).
    (b) Venturi scrubbers. (1) The owner or operator must monitor the 
pressure drop across the venturi at least every 5 minutes and record the 
average hourly pressure drop. Measurement of an average hourly pressure 
drop less than the pressure drop operating parameter limit established 
during a successful compliance demonstration would be a violation of the 
applicable emission standard, unless the excursion in the pressure drop 
is due to a malfunction.
    (2) As part of the maintenance plan required by Sec. 63.1655(b), 
the owner or operator must develop and implement corrective action 
procedures to be followed in the case of a violation of the pressure 
drop requirement. The owner or operator must initiate corrective action 
as soon as practicable after the excursion.
    (3) Failure to monitor or failure to take corrective action under 
the requirements of paragraph (b) of this section would be a violation 
of the general duty to operate in a manner consistent with good air 
pollution control practices that minimizes emissions per Sec. 
63.1652(f).
    (c) Shop opacity. The owner or operator subject to the opacity 
standards in Sec. 63.1653 must comply with one of the monitoring 
options in paragraphs (c)(1), (c)(2) or (c)(3) of this section. The 
selected option must be consistent with that selected during the initial 
performance test described in Sec. 63.1656(d)(2). Alternatively, the 
owner or operator may use the provisions of Sec. 63.8(f) to request 
approval to use an alternative monitoring method.
    (1) The owner or operator must check and record the control system 
fan motor amperes and capture system damper positions once per shift.
    (2) The owner or operator must install, calibrate, and maintain a 
monitoring device that continuously records the volumetric flow rate 
through each separately ducted hood.
    (3) The owner or operator must install, calibrate, and maintain a 
monitoring device that continuously records the volumetric flow rate at 
the inlet of the air pollution control device and must check and record 
the capture system damper positions once per shift.
    (4) The flow rate monitoring devices must meet the following 
requirements:
    (i) Be installed in an appropriate location in the exhaust duct such 
that reproducible flow rate monitoring will result.
    (ii) Have an accuracy 10 percent over its 
normal operating range and be

[[Page 218]]

calibrated according to the manufacturer's instructions.
    (5) The Administrator may require the owner or operator to 
demonstrate the accuracy of the monitoring device(s) relative to Methods 
1 and 2 of appendix A of part 60 of this chapter.
    (6) Failure to maintain the appropriate capture system parameters 
(fan motor amperes, flow rate, and/or damper positions) establishes the 
need to initiate corrective action as soon as practicable after the 
monitoring excursion in order to minimize excess emissions.
    (7) Failure to monitor or failure to take corrective action under 
the requirements of paragraph (c) of this section would be a violation 
of the general duty to operate in a manner consistent with good air 
pollution control practices that minimizes emissions per Sec. 
63.1652(f).

             General and Continuing Compliance Requirements



Sec. 63.1960  How is compliance determined?

    Compliance is determined in the same way it is determined for 40 CFR 
part 60, subpart WWW, including performance testing, monitoring of the 
collection system, continuous parameter monitoring, and other credible 
evidence. In addition, continuous parameter monitoring data, collected 
under 40 CFR 60.756(b)(1), (c)(1), and (d) of subpart WWW, are used to 
demonstrate compliance with the operating conditions for control 
systems. If a deviation occurs, you have failed to meet the control 
device operating conditions described in this subpart and have deviated 
from the requirements of this subpart. Finally, you must develop a 
written SSM plan according to the provisions in 40 CFR 63.6(e)(3). A 
copy of the SSM plan must be maintained on site. Failure to write or 
maintain a copy of the SSM plan is a deviation from the requirements of 
this subpart.

[68 FR 2238, Jan. 16, 2003, as amended at 71 FR 20462, Apr. 20, 2006]



Sec. 63.1965  What is a deviation?

    A deviation is defined in Sec. 63.1990. For the purposes of the 
landfill monitoring and SSM plan requirements, deviations include the 
items in paragraphs (a) through (c) of this section.
    (a) A deviation occurs when the control device operating parameter 
boundaries described in 40 CFR 60.758(c)(1) of subpart WWW are exceeded.
    (b) A deviation occurs when 1 hour or more of the hours during the 
3-hour block averaging period does not constitute a valid hour of data. 
A valid hour of data must have measured values for at least three 15-
minute monitoring periods within the hour.
    (c) A deviation occurs when a SSM plan is not developed or 
maintained on site.

[68 FR 2238, Jan. 16, 2003, as amended at 71 FR 20462, Apr. 20, 2006]



Sec. 63.1975  How do I calculate the 3-hour block average used to
demonstrate compliance?

    Averages are calculated in the same way as they are calculated in 40 
CFR

[[Page 226]]

part 60, subpart WWW, except that the data collected during the events 
listed in paragraphs (a), (b), (c), and (d) of this section are not to 
be included in any average computed under this subpart:
    (a) Monitoring system breakdowns, repairs, calibration checks, and 
zero (low-level) and high-level adjustments.
    (b) Startups.
    (c) Shutdowns.
    (d) Malfunctions.

                   Notifications, Records, and Reports



Sec. 63.1980  What records and reports must I keep and submit?

    (a) Keep records and reports as specified in 40 CFR part 60, subpart 
WWW, or in the Federal plan, EPA approved State plan or tribal plan that 
implements 40 CFR part 60, subpart Cc, whichever applies to your 
landfill, with one exception: You must submit the annual report 
described in 40 CFR 60.757(f) every 6 months.
    (b) You must also keep records and reports as specified in the 
general provisions of 40 CFR part 60 and this part as shown in Table 1 
of this subpart. Applicable records in the general provisions include 
items such as SSM plans and the SSM plan reports.
    (c) For bioreactors at new affected sources you must submit the 
initial semiannual compliance report and performance test results 
described in 40 CFR 60.757(f) within 180 days after the date you are 
required to begin operating the gas collection and control system by 
Sec. 63.1947(a)(2) of this subpart.
    (d) For bioreactors at existing affected sources, you must submit 
the initial semiannual compliance report and performance test results 
described in 40 CFR 60.757(f) within 180 days after the compliance date 
specified in Sec. 63.1947(b) of this subpart, unless you have 
previously submitted a compliance report for the bioreactor required by 
40 CFR part 60, subpart WWW, the Federal plan, or an EPA approved and 
effective State plan or tribal plan.
    (e) For bioreactors that are located at existing affected sources, 
but do not initiate liquids addition until later than the compliance 
date in Sec. 63.1947(b) of this subpart, you must submit the initial 
semiannual compliance report and performance tests results described in 
40 CFR 60.757(f) within 180 days after the date you are required to 
begin operating the gas collection and control system by Sec. 
63.1947(c) of this subpart.
    (f) If you must submit a semiannual compliance report for a 
bioreactor as well as a semiannual compliance report for a conventional 
portion of the same landfill, you may delay submittal of a subsequent 
semiannual compliance report for the bioreactor according to paragraphs 
(f)(1) through (3) of this section so that the reports may be submitted 
on the same schedule.
    (1) After submittal of your initial semiannual compliance report and 
performance test results for the bioreactor, you may delay submittal of 
the subsequent semiannual compliance report for the bioreactor until the 
date the initial or subsequent semiannual compliance report is due for 
the conventional portion of your landfill.
    (2) You may delay submittal of your subsequent semiannual compliance 
report by no more than 12 months after the due date for submitting the 
initial semiannual compliance report and performance test results 
described in 40 CFR 60.757(f) for the bioreactor. The report shall cover 
the time period since the previous semiannual report for the bioreactor, 
which would be a period of at least 6 months and no more than 12 months.
    (3) After the delayed semiannual report, all subsequent semiannual 
reports for the bioreactor must be submitted every 6 months on the same 
date the semiannual report for the conventional portion of the landfill 
is due.
    (g) If you add any liquids other than leachate in a controlled 
fashion to the waste mass and do not comply with the bioreactor 
requirements in Sec. Sec. 63.1947, 63.1955(c) and 63.1980(c) through 
(f) of this subpart, you must keep a record of calculations showing that 
the percent moisture by weight expected in the waste mass to which 
liquid is added is less than 40 percent. The calculation must consider 
the waste mass, moisture content of the incoming waste, mass of water 
added to the waste including leachate recirculation and other liquids 
addition and precipitation, and the mass of water removed through 
leachate or other water losses.

[[Page 227]]

Moisture level sampling or mass balances calculations can be used. You 
must document the calculations and the basis of any assumptions. Keep 
the record of the calculations until you cease liquids addition.
    (h) If you calculate moisture content to establish the date your 
bioreactor is required to begin operating the collection and control 
system under Sec. 63.1947(a)(2) or (c)(2), keep a record of the 
calculations including the information specified in paragraph (g) of 
this section for 5 years. Within 90 days after the bioreactor achieves 
40 percent moisture content, report the results of the calculation, the 
date the bioreactor achieved 40 percent moisture content by weight, and 
the date you plan to begin collection and control system operation.

 Subpart CCCC_National Emission Standards for Hazardous Air Pollutants: 
                   Manufacturing of Nutritional Yeast

    Source: 66 FR 27884, May 21, 2001, unless otherwise noted.

                        What This Subpart Covers



Sec. 63.2130  What is the purpose of this subpart?

    This subpart establishes national emission limitations for hazardous 
air pollutants emitted from manufacturers of nutritional yeast. This 
subpart also establishes requirements to demonstrate initial and 
continuous compliance with the emission limitations.



Sec. 63.2131  Am I subject to this subpart?

    (a) You are subject to this subpart if you own or operate a 
nutritional yeast manufacturing facility that is, is located at, or is 
part of a major source of hazardous air pollutants (HAP) emissions.
    (1) A manufacturer of nutritional yeast is a facility that makes 
yeast for the purpose of becoming an ingredient in dough for bread or 
any other yeast-raised baked product, or for becoming a nutritional food 
additive intended for consumption by humans. A manufacturer of 
nutritional yeast does not include production of yeast intended for 
consumption by animals, such as an additive for livestock feed.
    (2) A major source of HAP emissions is any stationary source or 
group of stationary sources located within a contiguous area and under 
common control that emits or has the potential to emit, considering 
controls, any single HAP at a rate of 9.07 megagrams (10 tons) or more 
per year or any combination of HAP at a rate of 22.68 megagrams (25 
tons) or more per year.
    (b) [Reserved]



Sec. 63.2132  What parts of my plant does this subpart cover?

    (a) This subpart applies to each new, reconstructed, or existing 
``affected source'' that produces Saccharomyces cerevisiae at a 
nutritional yeast manufacturing facility.
    (b) The affected source is the collection of equipment used in the 
manufacture of the nutritional yeast species Saccharomyces cerevisiae. 
This collection of equipment includes, but is not limited to, 
fermentation vessels (fermenters). The collection of equipment used in 
the manufacture of the nutritional yeast species Candida utilis (torula 
yeast) is not part of the affected source.
    (c) The emission limitations in this subpart apply to fermenters in 
the affected source that meet all of the criteria listed in paragraphs 
(c)(1) through (2) of this section.
    (1) The fermenters are ``fed-batch'' as defined in Sec. 63.2192.
    (2) The fermenters are used to support one of the last three 
fermentation stages in a production run, which may be referred to as 
``stock, first generation, and trade,'' ``seed, semi-seed, and 
commercial,'' or ``CB4, CB5, and CB6'' stages.
    (d) The emission limitations in this subpart do not apply to flask, 
pure-culture, yeasting-tank, or any other set-batch fermentation, and 
they do not apply to any operations after the last dewatering operation, 
such as filtration.
    (e) The emission limitations in this subpart do not apply to the 
affected source during the production of specialty yeast (defined in 
Sec. 63.2192).
    (f) An affected source is a ``new affected source'' if you commenced 
construction of the affected source after October 19, 1998, and you met 
the applicability criteria in Sec. 63.2131 at the time you commenced 
construction.
    (g) An affected source is ``reconstructed'' if you meet the criteria 
as defined in Sec. 63.2.
    (h) An affected source is ``existing'' if it is not new or 
reconstructed.



Sec. 63.2133  When do I have to comply with this subpart?

    (a) If you have a new or reconstructed affected source, you must 
comply with paragraphs (a)(1) through (2) of this section.
    (1) If you start up your affected source before May 21, 2001, then 
you must comply with the emission limitations in this subpart no later 
than May 21, 2001.
    (2) If you start up your affected source after May 21, 2001, then 
you

[[Page 230]]

must comply with the emission limitations in this subpart upon startup 
of your affected source.
    (b) If you have an existing affected source, you must comply with 
the emission limitations for existing sources no later than May 21, 
2004.
    (c) If you have an area source that increases its emissions, or its 
potential to emit, so that it becomes a major source of HAP, paragraphs 
(c)(1) through (2) of this section apply.
    (1) Any portion of the existing facility that is a new affected 
source or a new reconstructed source must be in compliance with this 
subpart upon startup.
    (2) All other parts of the source must be in compliance with this 
subpart by not later than 3 years after it becomes a major source.
    (d) You must meet the notification requirements in Sec. 63.2180 
according to the schedule in Sec. 63.2180 and in subpart A of this 
part.

                          Emission Limitations



Sec. 63.2140  What emission limitations must I meet?

    You must meet all of the emission limitations in Table 1 to this 
subpart.

                     General Compliance Requirements



Sec. 63.2150  What are my general requirements for complying with
this subpart?

    (a) You must be in compliance with the emission limitations in Table 
1 to this subpart at all times, except during periods of malfunction.
    (b) You must always operate and maintain your affected source, 
including monitoring equipment, according to the provisions in Sec. 
63.6(e)(1)(i). If the date upon which you must demonstrate initial 
compliance as specified in Sec. 63.2160 falls after the compliance date 
specified for your affected source in Sec. 63.2133, then you must 
maintain a log detailing the operation and maintenance of the continuous 
monitoring systems and the process and emissions control equipment 
during the period between those dates.
    (c) You must develop a written malfunction plan. It will be as 
specified in Sec. 63.6(e)(3), except that the requirements for startup, 
shutdown, and maintenance plans, records and reports apply only to 
malfunctions. Under this subpart, a period of malfunction is expressed 
in whole batches and not in portions of batches.

               Testing and Initial Compliance Requirements



Sec. 63.2160  By what date must I conduct an initial compliance 
demonstration?

    (a) For each emission limitation in Table 1 to this subpart for 
which compliance is demonstrated by monitoring fermenter exhaust, you 
must demonstrate initial compliance for the period ending on the last 
day of the month that is 12 calendar months (or 11 calendar months, if 
the compliance date for your source is the first day of the month) after 
the compliance date that is specified for your source in Sec. 63.2133. 
(For example, if the compliance date is October 15, 2003, the first 12-
month period for which you must demonstrate compliance would be October 
15, 2003 through October 31, 2004.)
    (b) For each emission limitation in Table 1 to this subpart for 
which initial compliance is demonstrated by monitoring brew ethanol 
concentration and calculating volatile organic compound (VOC) 
concentration in the fermenter exhaust according to the procedures in 
Sec. 63.2161, you must demonstrate initial compliance within 180 
calendar days before the compliance date that is specified for your 
source in Sec. 63.2133.



Sec. 63.2161  What performance tests and other procedures must
I use if I monitor brew ethanol?

    (a) You must conduct each performance test in Table 2 to this 
subpart that applies to you.
    (b) Each performance test must be conducted according to the 
requirements in Sec. 63.7(e)(1) and under the specific conditions that 
this subpart specifies in Table 2 to this subpart and in paragraphs 
(b)(1) through (4) of this section.
    (1) Conduct each performance test simultaneously with brew ethanol 
monitoring to establish a brew-to-exhaust

[[Page 231]]

correlation equation as specified in paragraph (f) of this section.
    (2) For each fermentation stage, conduct one run of the EPA Test 
Method 25A of 40 CFR part 60, appendix A, over the entire length of a 
batch. The three fermentation stages do not have to be from the same 
production run.
    (3) Do the test at a point in the exhaust-gas stream before you 
inject any dilution air, which is any air not needed to control 
fermentation.
    (4) Record the results of the test for each fermentation stage.
    (c) You may not conduct performance tests during periods of startup, 
shutdown, or malfunction, as specified in Sec. 63.7(e)(1).
    (d) You must collect data to correlate the brew ethanol 
concentration measured by the continuous emission monitoring system 
(CEMS) to the VOC concentration in the fermenter exhaust according to 
paragraphs (d)(1) through (3) of this section.
    (1) You must collect a separate set of brew ethanol concentration 
data for each fed-batch fermentation stage while manufacturing the 
product that comprises the largest percentage (by mass) of average 
annual production.
    (2) Measure brew ethanol as specified in Sec. 63.2164 
simultaneously with conducting a performance test for VOC in fermenter 
exhaust as specified in paragraph (b) of this section. You must measure 
brew ethanol at least once during each successive 30-minute period over 
the entire period of the performance test for VOC in fermenter exhaust.
    (3) Keep a record of the brew ethanol concentration data for each 
fermentation stage over the period of EPA Test Method 25A of 40 CFR part 
60, appendix A, performance test when the VOC concentration in the 
fermenter exhaust does not exceed the applicable emission limitation in 
Table 1 to this subpart.
    (e) For each set of data that you collected under paragraph (d) of 
this section, perform a linear regression of brew ethanol concentration 
(percent) on VOC fermenter exhaust concentration (parts per million by 
volume (ppmv) measured as propane). The correlation between the brew 
ethanol concentration as measured by the CEMS and the VOC fermenter 
exhaust concentration as measured by EPA Test Method 25A of 40 CFR part 
60, appendix A, must be linear with a correlation coefficient of at 
least 0.90.
    (f) Calculate the VOC concentration in the fermenter exhaust using 
the brew ethanol concentration data collected under paragraph (d) of 
this section and according to Equation 1 of this section.

BAVOC = BAE * CF + y (Eq. 1)

Where:

BAVOC = batch-average concentration of VOC in fermenter exhaust (ppmv 
          measured as propane), calculated for compliance demonstration
BAE = batch-average concentration of brew ethanol in fermenter liquid 
          (percent), measured by CEMS
CF = constant established at performance test and representing the slope 
          of the regression line
y = constant established at performance test and representing the y-
          intercept of the regression line



Sec. 63.2162  When must I conduct subsequent performance tests?

    (a) For each emission limitation in Table 1 to this subpart for 
which compliance is demonstrated by monitoring brew ethanol 
concentration and calculating VOC concentration in the fermenter exhaust 
according to the procedures in Sec. 63.2161, you must conduct an EPA 
Test Method 25A of 40 CFR part 60, appendix A, performance test and 
establish a brew-to-exhaust correlation according to the procedures in 
Table 2 to this subpart and in Sec. 63.2161, at least once every year.
    (b) The first subsequent performance test must be conducted no later 
than 365 calendar days after the initial performance test conducted 
according to Sec. 63.2160. Each subsequent performance test must be 
conducted no later than 365 calendar days after the previous performance 
test. You must conduct a performance test for each 365 calendar day 
period for the lifetime of the affected source.



Sec. 63.2163  If I monitor fermenter exhaust, what are my monitoring
installation, operation, and maintenance requirements?

    (a) Each CEMS must be installed, operated, and maintained according 
to

[[Page 232]]

the applicable Performance Specification (PS) of 40 CFR part 60, 
appendix B.
    (b) You must conduct a performance evaluation of each CEMS according 
to the requirements in Sec. 63.8, according to the applicable 
Performance Specification of 40 CFR part 60, appendix B, and according 
to paragraphs (b)(1) through (4) of this section.
    (1) If your CEMS monitor generates a single combined response value 
for VOC (examples of such detection principles are flame ionization, 
photoionization, and non-dispersive infrared absorption), but it is not 
a flame ionization analyzer, you must use PS 8 to show that your CEMS is 
operating properly.
    (i) Use EPA Test Method 25A of 40 CFR part 60, appendix A, to do the 
relative-accuracy test PS 8 requires.
    (ii) Calibrate the reference method with propane.
    (iii) Collect a 1-hour sample for each reference-method test.
    (2) If you continuously monitor VOC emissions using a flame 
ionization analyzer, then you must conduct the calibration drift test PS 
8 requires, but you are not required to conduct the relative-accuracy 
test PS 8 requires.
    (3) If you continuously monitor VOC emissions using gas 
chromatography, you must use PS 9 of CFR part 60, appendix B, to show 
that your CEMS is operating properly.
    (4) You must complete the performance evaluation and submit the 
performance evaluation report before the compliance date that is 
specified for your source in Sec. 63.2133.
    (c) Calibrate the CEMS with propane.
    (d) Set the CEMS span at not greater than 5 times the relevant 
emission limit, with 1.5 to 2.5 times the relevant emission limit being 
the range considered by us to be generally optimum.
    (e) You must monitor VOC concentration in fermenter exhaust at any 
point prior to dilution of the exhaust stream.
    (f) Each CEMS must complete a minimum of one cycle of operation 
(sampling, analyzing, and data recording) for each successive 30-minute 
period within each batch monitoring period. Except as specified in 
paragraph (g) of this section, you must have a minimum of two cycles of 
operation in a 1-hour period to have a valid hour of data.
    (g) The CEMS data must be reduced to arithmetic batch averages 
computed from two or more data points over each 1-hour period, except 
during periods when calibration, quality assurance, or maintenance 
activities pursuant to provisions of this part are being performed. 
During these periods, a valid hour of data shall consist of at least one 
data point representing a 30-minute period.
    (h) You must have valid CEMS data from at least 75 percent of the 
full hours over the entire batch monitoring period.
    (i) For each CEMS, record the results of each inspection, 
calibration, and validation check.
    (j) You must check the zero (low-level) and high-level calibration 
drifts for each CEMS in accordance with the applicable PS of 40 CFR part 
60, appendix B. The zero (low-level) and high-level calibration drifts 
shall be adjusted, at a minimum, whenever the zero (low-level) drift 
exceeds 2 times the limits of the applicable PS. The calibration drift 
checks must be performed at least once daily except that they may be 
performed less frequently under the conditions of paragraphs (j)(1) 
through (3) of this section.
    (1) If a 24-hour calibration drift check for your CEMS is performed 
immediately prior to, or at the start of, a batch monitoring period of a 
duration exceeding 24 hours, you are not required to perform 24-hour-
interval calibration drift checks during that batch monitoring period.
    (2) If the 24-hour calibration drift exceeds 2.5 percent of the span 
value (or more than 10 percent of the calibration gas value if your CEMS 
is a gas chromatograph (GC)) in fewer than 5 percent of the checks over 
a 1-month period, and the 24-hour calibration drift never exceeds 7.5 
percent of the span value, then the frequency of calibration drift 
checks may be reduced to at least weekly (once every 7 days).
    (3) If, during two consecutive weekly checks, the weekly calibration 
drift exceeds 5 percent of the span value (or more than 20 percent of 
the calibration gas value, if your CEMS is a GC), then a frequency of at 
least 24-hour interval

[[Page 233]]

calibration checks must be resumed until the 24-hour calibration checks 
meet the test of paragraph (j)(2) of this section.
    (k) If your CEMS is out of control, you must take corrective action 
according to paragraphs (k)(1) through (3) of this section.
    (1) Your CEMS is out of control if the zero (low-level) or high-
level calibration drift exceeds 2 times the limits of the applicable PS.
    (2) When the CEMS is out of control, take the necessary corrective 
action and repeat all necessary tests that indicate that the system is 
out of control. You must take corrective action and conduct retesting 
until the performance requirements are below the applicable limits.
    (3) During the batch monitoring periods in which the CEMS is out of 
control, recorded data shall not be used in data averages and 
calculations, or to meet any data availability requirement established 
under this subpart. The beginning of the out-of-control period is the 
beginning of the first batch monitoring period that follows the most 
recent calibration drift check during which the system was within 
allowable performance limits. The end of the out-of-control period is 
the end of the last batch monitoring period before you have completed 
corrective action and successfully demonstrated that the system is 
within the allowable limits. If your successful demonstration that the 
system is within the allowable limits occurs during a batch monitoring 
period, then the out-of-control period ends at the end of that batch 
monitoring period. If the CEMS is out of control for any part of a 
particular batch monitoring period, it is out of control for the whole 
batch monitoring period.



Sec. 63.2164  If I monitor brew ethanol, what are my monitoring 
installation, operation, and maintenance requirements?

    (a) Each CEMS must be installed, operated, and maintained according 
to manufacturer's specifications and in accordance with Sec. 
63.6(e)(1).
    (b) Each CEMS must complete a minimum of one cycle of operation 
(sampling, analyzing, and data recording) for each successive 30-minute 
period within each batch monitoring period. Except as specified in 
paragraph (c) of this section, you must have a minimum of two cycles of 
operation in a 1-hour period to have a valid hour of data.
    (c) The CEMS data must be reduced to arithmetic batch averages 
computed from two or more data points over each 1-hour period, except 
during periods when calibration, quality assurance, or maintenance 
activities pursuant to provisions of this part are being performed. 
During these periods, a valid hour of data shall consist of at least one 
data point representing a 30-minute period.
    (d) You must have valid CEMS data from at least 75 percent of the 
full hours over the entire batch monitoring period.
    (e) Set the CEMS span to correspond to not greater than 5 times the 
relevant emission limit, with 1.5 to 2.5 times the relevant emission 
limit being the range considered by us to be generally optimum. Use the 
brew-to-exhaust correlation equation established under Sec. 63.2161(f) 
to determine the span value for your CEMS that corresponds to the 
relevant emission limit.
    (f) For each CEMS, record the results of each inspection, 
calibration, and validation check.
    (g) The GC that you use to calibrate your CEMS must meet the 
requirements of paragraphs (g)(1) through (3) of this section.
    (1) Calibrate the GC at least daily, by analyzing standard solutions 
of ethanol in water (0.05 percent, 0.15 percent, and 0.3 percent).
    (2) For use in calibrating the GC, prepare the standard solutions of 
ethanol using the procedures listed in paragraphs (g)(2)(i) through (vi) 
of this section.
    (i) Starting with 100 percent ethanol, dry the ethanol by adding a 
small amount of anhydrous magnesium sulfate (granular) to 15-20 
milliliters (ml) of ethanol.
    (ii) Place approximately 50 ml of water into a 100-ml volumetric 
flask and place the flask on a balance. Tare the balance. Weigh 2.3670 
grams of the dry (anhydrous) ethanol into the volumetric flask.

[[Page 234]]

    (iii) Add the 100-ml volumetric flask contents to a 1000-ml 
volumetric flask. Rinse the 100-ml volumetric flask with water into the 
1000-ml flask. Bring the volume to 1000 ml with water.
    (iv) Place an aliquot into a sample bottle labeled ``0.3% Ethanol.''
    (v) Fill a 50-ml volumetric flask from the contents of the 1000-ml 
flask. Add the contents of the 50-ml volumetric flask to a 100-ml 
volumetric flask and rinse the 50-ml flask into the 100-ml flask with 
water. Bring the volume to 100 ml with water. Place the contents into a 
sample bottle labeled ``0.15% Ethanol.''
    (vi) With a 10-ml volumetric pipette, add two 10.0-ml volumes of 
water to a sample bottle labeled ``0.05% Ethanol.'' With a 10.0-ml 
volumetric pipette, pipette 10.0 ml of the 0.15 percent ethanol solution 
into the sample bottle labeled ``0.05% Ethanol.''
    (3) For use in calibrating the GC, dispense samples of the standard 
solutions of ethanol in water in aliquots to appropriately labeled and 
dated glass sample bottles fitted with caps having a Teflon [supreg] 
seal. Refrigerated samples may be kept unopened for 1 month. Prepare new 
calibration standards of ethanol in water at least monthly.
    (h) Calibrate the CEMS according to paragraphs (h)(1) through (3) of 
this section.
    (1) To calibrate the CEMS, inject a brew sample into a calibrated GC 
and compare the simultaneous ethanol value given by the CEMS to that 
given by the GC. Use either the Porapak [supreg] Q, 80-100 mesh, 6[min] 
x \1/8\[min], stainless steel packed column or the DB Wax, 0.53 mm x 30 
m capillary column.
    (2) If a CEMS ethanol value differs by 20 percent or more from the 
corresponding GC ethanol value, determine the brew ethanol values 
throughout the rest of the batch monitoring period by injecting brew 
samples into the GC not less frequently than every 30 minutes. From the 
time at which the difference of 20 percent or more is detected until the 
batch monitoring period ends, the GC data will serve as the CEMS data.
    (3) Perform a calibration of the CEMS at least four times per batch.

limitation that applies to you according to Table 3 to this subpart.
    (b) You must submit the Notification of Compliance Status containing 
the results of the initial compliance demonstration according to the 
requirements in Sec. 63.2180(e).



Sec. 63.2166  How do I demonstrate initial compliance with the emission
limitations if I monitor brew ethanol?

    (a) You must demonstrate initial compliance with each emission 
limitation that applies to you according to Table 3 to this subpart.
    (b) You must establish the brew-to-exhaust correlation for each 
fermentation stage according to Sec. 63.2161(e).
    (c) You must submit the Notification of Compliance Status containing 
the results of the initial compliance demonstration according to the 
requirements in Sec. 63.2180(e).

                   Continuous Compliance Requirements



Sec. 63.2170  How do I monitor and collect data to demonstrate
continuous compliance?

    (a) You must monitor and collect data according to this section.
    (b) Except for monitor malfunctions, associated repairs, and 
required quality assurance or control activities (including, as 
applicable, calibration checks and required zero and span adjustments), 
you must monitor continuously during each batch monitoring period.
    (c) You may not use data recorded during monitoring malfunctions, 
associated repairs, and required quality assurance or quality control 
activities in data averages and calculations used to report emission or 
operating levels, or to fulfill a minimum data availability requirement. 
You must use all the data collected during all other periods in 
assessing the operation of the control system.

[[Page 235]]



Sec. 63.2171  How do I demonstrate continuous compliance with the 
emission limitations?

    (a) You must demonstrate continuous compliance with each emission 
limitation in Table 1 to this subpart that applies to you according to 
methods specified in Table 4 to this subpart.
    (b) You must calculate the percentage of within-concentration 
batches (defined in Sec. 63.2192) for each 12-month period according to 
paragraphs (b)(1) through (4) of this section.
    (1) Determine the percentage of batches over a 12-month calculation 
period that were in compliance with the applicable maximum 
concentration. The total number of batches in the calculation period is 
the sum of the numbers of batches of each fermentation stage for which 
emission limits apply. To calculate the 12-month percentage, do not 
include batches in production during periods of malfunction. In counting 
the number of batches in the 12-month calculation period, include those 
batches for which the batch monitoring period ended on or after 12 a.m. 
on the first day of the period and exclude those batches for which the 
batch monitoring period did not end on or before 11:59 p.m. on the last 
day of the period.
    (2) You must determine the 12-month percentage at the end of each 
calendar month.
    (3) The first 12-month calculation period begins on the compliance 
date that is specified for your source in Sec. 63.2133 and ends on the 
last day of the month that includes the date 365 days after your 
compliance date, unless the compliance date for your source is the first 
day of the month, in which case the first 12-month calculation period 
ends on the last day of the month that is 11 calendar months after the 
compliance date. (For example, if the compliance date for your source is 
October 15, 2003, the first 12-month calculation period would begin on 
October 15, 2003, and end on October 31, 2004. If the compliance date 
for your source is October 1, 2003, the first 12-month calculation 
period would begin on October 1, 2003, and end on September 30, 2004.)
    (4) The second 12-month calculation period and each subsequent 12-
month calculation period begin on the first day of the month following 
the first full month of the previous 12-month averaging period and end 
on the last day of the month 11 calendar months later. (For example, if 
the compliance date for your source is October 15, 2003, the second 
calculation period would begin on December 1, 2003 and end on November 
30, 2004.)
    (c) You must report each instance (that is, each 12-month 
calculation period) in which you did not meet each emission requirement 
in Table 4 to this subpart that applies to you. (Failure of a single 
batch to meet a concentration limit does not in and of itself constitute 
a failure to meet the emission limitation.) Each instance in which you 
failed to meet each applicable emission limitation is reported as part 
of the requirements in Sec. 63.2181.

Sec. 63.2180  What notifications must I submit and when?

    (a) You must submit all of the notifications in Sec. Sec. 63.7(b) 
and (c), 63.8(e), (f)(4) and (6), and 63.9(b) through (h) that apply to 
you by the dates specified.
    (b) If you start up your affected source before May 21, 2001, you 
are not subject to the initial notification requirements of Sec. 
63.9(b)(2).
    (c) If you are required to conduct a performance test as specified 
in Table 2 to this subpart, you must submit a notification of intent to 
conduct a performance test at least 60 calendar days before the 
performance test is scheduled to begin as required in Sec. 63.7(b)(1).
    (d) If you are required to conduct a performance evaluation as 
specified in Sec. 63.2163(b), you must submit a notification of the 
date of the performance evaluation at least 60 days prior to the date 
the performance evaluation is scheduled to begin as required in Sec. 
63.8(e)(2).
    (e) If you are required to conduct a performance test or other 
initial compliance demonstration as specified in Table 2 or 3 to this 
subpart, you must submit a Notification of Compliance Status according 
to Sec. 63.9(h)(2)(ii) and according to paragraphs (e)(1) through (2) 
of this section.

[[Page 236]]

    (1) For each initial compliance demonstration required in Table 3 to 
this subpart that does not include a performance test, you must submit 
the Notification of Compliance Status no later than July 31 or January 
31, whichever date follows the end of the first 12 calendar months after 
the compliance date that is specified for your source in Sec. 63.2133. 
If your initial compliance demonstration does not include a performance 
test, the first compliance report, described in Sec. 63.2181(b)(1), 
serves as the Notice of Compliance Status.
    (2) For each initial compliance demonstration required in Table 2 or 
3 to this subpart that includes a performance test conducted according 
to the requirements in Table 2, you must submit the Notification of 
Compliance Status, including the performance test results, before the 
close of business on the 60th calendar day following the completion of 
the performance test according to Sec. 63.10(d)(2).



Sec. 63.2181  What reports must I submit and when?

    (a) You must submit each report in Table 5 to this subpart that 
applies to you.
    (b) Unless the Administrator has approved a different schedule for 
submission of reports under Sec. 63.10(a), you must submit each report 
by the date in Table 5 to this subpart and according to paragraphs 
(b)(1) through (5) of this section.
    (1) The first compliance report must cover the period beginning on 
the compliance date that is specified for your affected source in Sec. 
63.2133 and ending on either June 30 or December 31 (use whichever date 
is the first date following the end of the first 12 calendar months 
after the compliance date that is specified for your source in Sec. 
63.2133). The first compliance report must include the percentage of 
within-concentration batches, as described in Sec. 63.2171(b), for the 
first 12-month calculation period described in Sec. 63.2171(b)(3). It 
must also include a percentage for each subsequent 12-month calculation 
period, as described in Sec. 63.2171(b)(4), ending on a calendar month 
that falls within the first compliance period. (For example, if the 
compliance date for your source is October 15, 2003, the first 
compliance report would cover the period from October 15, 2003 to 
December 31, 2004. It would contain percentages for the 12-month periods 
ending October 31, 2004; November 30, 2004; and December 31, 2004.)
    (2) The first compliance report must be postmarked or delivered no 
later than July 31 or January 31, whichever date follows the end of the 
first 12 calendar months after the compliance date that is specified for 
your affected source in Sec. 63.2133.
    (3) Each subsequent compliance report must cover the semiannual 
reporting period from January 1 through June 30 or the semiannual 
reporting period from July 1 through December 31. Each subsequent 
compliance report must include the percentage of within-concentration 
batches for each 12-month calculation period ending on a calendar month 
that falls within the reporting period. (For example, if the compliance 
date for your source is October 15, 2003, the second compliance report 
would cover the period from January 1, 2005 through June 30, 2005. It 
would contain percentages for the 12-month periods ending January 31, 
2005; February 28, 2005; March 31, 2005; April 30, 2005; May 31, 2005; 
and June 30, 2005.)
    (4) Each subsequent compliance report must be postmarked or 
delivered no later than July 31 or January 31, whichever date is the 
first date following the end of the semiannual reporting period.
    (5) For each affected source that is subject to permitting 
regulations pursuant to 40 CFR part 70 or part 71, and if the permitting 
authority has established dates for submitting semiannual reports 
pursuant to 40 CFR 70.6(a)(3)(a)(iii)(A) or 40 CFR 
71.6(a)(3)(a)(iii)(A), you may submit the first and subsequent 
compliance reports according to the dates the permitting authority has 
established instead of according to the dates in paragraphs (b)(1) 
through (4) of this section.
    (c) The compliance report must contain the information listed in 
paragraphs (c)(1) through (5) of this section.
    (1) Company name and address.
    (2) Statement by a responsible official with that official's name, 
title, and

[[Page 237]]

signature, certifying the accuracy of the content of the report.
    (3) Date of report and beginning and ending dates of the reporting 
period.
    (4) Percentage of batches that are within-concentration batches for 
each 12-month period ending on a calendar month that falls within the 
reporting period.
    (5) If you had a malfunction during the reporting period and you 
took actions consistent with your malfunction plan, the compliance 
report must include the information in Sec. 63.10(d)(5)(i) for each 
malfunction.



Sec. 63.2182  What records must I keep?

    (a) You must keep the records listed in paragraphs (a)(1) through 
(4) of this section. These include:

Sec. 63.2192  What definitions apply to this subpart?

    Terms used in this subpart are defined in the Clean Air Act, in 40 
CFR 63.2, the General Provisions of this part, and in this section as 
follows:
    Batch means a single fermentation cycle in a single fermentation 
vessel (fermenter).
    Batch monitoring period means the period that begins at the later of 
either the start of aeration or the addition of yeast to the fermenter; 
the period ends at the earlier of either the end of aeration or the 
point at which the yeast has begun being emptied from the fermenter.
    Brew means the mixture of yeast and additives in the fermenter.
    Brew ethanol means the ethanol in fermenter liquid.
    Brew ethanol monitor means the monitoring system that you use to 
measure brew ethanol to demonstrate compliance with this subpart. The 
monitoring system includes a resistance element used as an ethanol 
sensor, with the measured resistance proportional to the concentration 
of ethanol in the brew.
    Brew-to-exhaust correlation means the correlation between the 
concentration of ethanol in the brew and the concentration of VOC in the 
fermenter exhaust. This correlation is specific to each fed-batch 
fermentation stage and is established while manufacturing the product 
that comprises the largest percentage (by mass) of average annual 
production.
    Emission limitation means any emission limit or operating limit.
    Fed-batch means the yeast is fed carbohydrates and additives during 
fermentation in the vessel. In contrast, carbohydrates and additives are 
added to ``set-batch'' fermenters only at the start of the batch.
    1-hour period means any 60-minute period commencing on the minute at 
which the batch monitoring period begins.
    Product means the yeast resulting from the final stage in a 
production run. Products are distinguished by yeast species, strain, and 
variety.
    Responsible official means responsible official as defined in 40 CFR 
70.2.
    Specialty yeast includes but is not limited to yeast produced for 
use in wine, champagne, whiskey, and beer.
    Within-concentration batch means a batch for which the average VOC 
concentration is not higher than the maximum concentration that is 
allowed as part of the applicable emission limitation.

                   Plywood and Composite Wood Products

                        What This Subpart Covers

    Source: 69 FR 46011, July 30, 2004, unless otherwise noted.



Sec. 63.2230  What is the purpose of this subpart?

    This subpart establishes national compliance options, operating 
requirements, and work practice requirements for hazardous air 
pollutants (HAP) emitted from plywood and composite wood products (PCWP) 
manufacturing facilities. This subpart also establishes requirements to 
demonstrate initial and continuous compliance with the compliance 
options, operating requirements, and work practice requirements.



Sec. 63.2231  Does this subpart apply to me?

    This subpart applies to you if you meet the criteria in paragraphs 
(a) and (b) of this section.
    (a) You own or operate a PCWP manufacturing facility. A PCWP 
manufacturing facility is a facility that manufactures plywood and/or 
composite wood products by bonding wood material (fibers, particles, 
strands, veneers, etc.) or agricultural fiber, generally with resin 
under heat and pressure, to form a structural panel or engineered

wood product. Plywood and composite wood products manufacturing 
facilities also include facilities that manufacture dry veneer and 
lumber kilns located at any facility. Plywood and composite wood 
products include, but are not limited to, plywood, veneer, 
particleboard, oriented strandboard, hardboard, fiberboard, medium 
density fiberboard, laminated strand lumber, laminated veneer lumber, 
wood I-joists, kiln-dried lumber, and glue-laminated beams.
    (b) The PCWP manufacturing facility is located at a major source of 
HAP emissions. A major source of HAP emissions is any stationary source 
or group of stationary sources within a contiguous area and under common 
control that emits or has the potential to emit any single HAP at a rate 
of 9.07 megagrams (10 tons) or more per year or any combination of HAP 
at a rate of 22.68 megagrams (25 tons) or more per year.

Sec. 63.2232  What parts of my plant does this subpart cover?

    (a) This subpart applies to each new, reconstructed, or existing 
affected source at a PCWP manufacturing facility.
    (b) The affected source is the collection of dryers, refiners, 
blenders, formers, presses, board coolers, and other process units 
associated with the manufacturing of plywood and composite wood 
products. The affected source includes, but is not limited to, green end 
operations, refining, drying operations (including any combustion unit 
exhaust stream routinely used to direct fire process unit(s)), resin 
preparation, blending and forming operations, pressing and board cooling 
operations, and miscellaneous finishing operations (such as sanding, 
sawing, patching, edge sealing, and other finishing operations not 
subject to other national emission standards for hazardous air 
pollutants (NESHAP)). The affected source also includes onsite storage 
and preparation of raw materials used in the manufacture of plywood and/
or composite wood products, such as resins; onsite wastewater treatment 
operations specifically associated with plywood and composite wood 
products manufacturing; and miscellaneous coating operations (Sec. 
63.2292). The affected source includes lumber kilns at PCWP 
manufacturing facilities and at any other kind of facility.
    (c) An affected source is a new affected source if you commenced 
construction of the affected source after January 9, 2003, and you meet 
the applicability criteria at the time you commenced construction.
    (d) An affected source is reconstructed if you meet the criteria as 
defined in Sec. 63.2.
    (e) An affected source is existing if it is not new or 
reconstructed.

Sec. 63.2233  When do I have to comply with this subpart?

    (a) If you have a new or reconstructed affected source, you must 
comply with this subpart according to paragraph (a)(1) or (2) of this 
section, whichever is applicable.
    (1) If the initial startup of your affected source is before 
September 28, 2004, then you must comply with the compliance options, 
operating requirements, and work practice requirements for new and 
reconstructed sources in this subpart no later than September 28, 2004.
    (2) If the initial startup of your affected source is after 
September 28, 2004, then you must comply with the compliance options, 
operating requirements, and work practice requirements for new and 
reconstructed sources in this subpart upon initial startup of your 
affected source.
    (b) If you have an existing affected source, you must comply with 
the compliance options, operating requirements, and work practice 
requirements for existing sources no later than October 1, 2007.
    (c) If you have an area source that increases its emissions or its 
potential to emit such that it becomes a major source of HAP, you must 
be in compliance with this subpart by October 1, 2007 or upon initial 
startup of your affected source as a major source, whichever is later.
    (d) You must meet the notification requirements according to the 
schedule

[[Page 243]]

in Sec. 63.2280 and according to 40 CFR part 63, subpart A. Some of the

     Compliance Options, Operating Requirements, and Work Practice 
                              Requirements



Sec. 63.2240  What are the compliance options and operating 
requirements and how must I meet them?

    You must meet the compliance options and operating requirements 
described in Tables 1A, 1B, and 2 to this subpart and in paragraph (c) 
of this section by using one or more of the compliance options listed in 
paragraphs (a), (b), and (c) of this section. The process units subject 
to the compliance options are listed in Tables 1A and 1B to this subpart 
and are defined in Sec. 63.2292. You need only to meet one of the 
compliance options outlined in paragraphs (a) through (c) of this 
section for each process unit. You cannot combine compliance options in 
paragraph (a), (b), or (c) for a single process unit. (For example, you 
cannot use a production-based compliance option in paragraph (a) for one 
vent of a veneer dryer and an add-on control system compliance option in 
paragraph (b) for another vent on the same veneer dryer. You must use 
either the production-based compliance option or an add-on control 
system compliance option for the entire dryer.)
    (a) Production-based compliance options. You must meet the 
production-based total HAP compliance options in Table 1A to this 
subpart and the applicable operating requirements in Table 2 to this 
subpart. You may not use an add-on control system or wet control device 
to meet the production-based compliance options.
    (b) Compliance options for add-on control systems. You must use an 
emissions control system and demonstrate that the resulting emissions 
meet the compliance options and operating requirements in Tables 1B and 
2 to this subpart. If you own or operate a reconstituted wood product 
press at a new or existing affected source or a reconstituted wood 
product board cooler at a new affected source, and you choose to comply 
with one of the concentration-based compliance options for a control 
system outlet (presented as option numbers 2, 4, and 6 in Table 1B to 
this subpart), you must have a capture device that either meets the 
definition of wood products enclosure in Sec. 63.2292 or achieves a 
capture efficiency of greater than or equal to 95 percent.
    (c) Emissions averaging compliance option (for existing sources 
only). Using the procedures in paragraphs (c)(1) through (3) of this 
section, you must demonstrate that emissions included in the emissions 
average meet the compliance options and operating requirements. New 
sources may not use emissions averaging to comply with this subpart.
    (1) Calculation of required and actual mass removal. Limit emissions 
of total HAP, as defined in Sec. 63.2292, to include acetaldehyde, 
acrolein, formaldehyde, methanol, phenol, and propionaldehyde from your 
affected source to the standard specified by Equations 1, 2, and 3 of 
this section.

Where:

RMR = required mass removal of total HAP from all process units 
          generating debits (i.e., all process units that are subject to 
          the compliance options in Tables 1A and 1B to this subpart and 
          that are either uncontrolled or under-controlled), pounds per 
          semiannual period;
AMR = actual mass removal of total HAP from all process units generating 
          credits (i.e., all process units that are controlled as part 
          of the Emissions Averaging Plan including credits from debit-
          generating process units that are under-controlled), pounds 
          per semiannual period;
UCEPi = mass of total HAP from an uncontrolled or under-
          controlled process unit (i) that generates debits, pounds per 
          hour;

[[Page 244]]

OHi = number of hours a process unit (i) is operated during 
          the semiannual period, hours per 6-month period;
CDi = control system efficiency for the emission point (i) 
          for total HAP, expressed as a fraction, and not to exceed 90 
          percent, unitless (Note: To calculate the control system 
          efficiency of biological treatment units that do not meet the 
          definition of biofilter in Sec. 63.2292, you must use 40 CFR 
          part 63, appendix C, Determination of the Fraction Biodegraded 
          (Fbio) in a Biological Treatment Unit.);
OCEPi = mass of total HAP from a process unit (i) that 
          generates credits (including credits from debit-generating 
          process units that are under-controlled), pounds per hour;
0.90 = required control system efficiency of 90 percent multiplied, 
          unitless.

    (2) Requirements for debits and credits. You must calculate debits 
and credits as specified in paragraphs (c)(2)(i) through (vi) of this 
section.
    (i) You must limit process units in the emissions average to those 
process units located at the existing affected source as defined in 
Sec. 63.2292.
    (ii) You cannot use nonoperating process units to generate emissions 
averaging credits. You cannot use process units that are shut down to 
generate emissions averaging debits or credits.
    (iii) You may not include in your emissions average process units 
controlled to comply with a State, Tribal, or Federal rule other than 
this subpart.
    (iv) You must use actual measurements of total HAP emissions from 
process units to calculate your required mass removal (RMR) and actual 
mass removal (AMR). The total HAP measurements must be obtained 
according to Sec. 63.2262(b) through (d), (g), and (h), using the 
methods specified in Table 4 to this subpart.
    (v) Your initial demonstration that the credit-generating process 
units will be capable of generating enough credits to offset the debits 
from the debit-generating process units must be made under 
representative operating conditions. After the compliance date, you must 
use actual operating data for all debit and credit calculations.
    (vi) Do not include emissions from the following time periods in 
your emissions averaging calculations:
    (A) Emissions during periods of startup, shutdown, and malfunction 
as described in the startup, shutdown, and malfunction plan (SSMP).
    (B) Emissions during periods of monitoring malfunctions, associated 
repairs, and required quality assurance or control activities or during 
periods of control device maintenance covered in your routine control 
device maintenance exemption. No credits may be assigned to credit-
generating process units, and maximum debits must be assigned to debit-
generating process units during these periods.
    (3) Operating requirements. You must meet the operating requirements 
in Table 2 to this subpart for each process unit or control device used 
in calculation of emissions averaging credits.



Sec. 63.2241  What are the work practice requirements and how must
I meet them?

    (a) You must meet each work practice requirement in Table 3 to this 
subpart that applies to you.
    (b) As provided in Sec. 63.6(g), we, the EPA, may choose to grant 
you permission to use an alternative to the work practice requirements 
in this section.
    (c) If you have a dry rotary dryer, you may choose to designate your 
dry rotary dryer as a green rotary dryer and meet the more stringent 
compliance options and operating requirements in Sec. 63.2240 for green 
rotary dryers instead of the work practices for dry rotary dryers. If 
you have a hardwood veneer dryer or veneer redryer, you may choose to 
designate your hardwood veneer dryer or veneer redryer as a softwood 
veneer dryer and meet the more stringent compliance options and 
operating requirements in Sec. 63.2240 for softwood veneer dryer heated 
zones instead of the work practices for hardwood veneer dryers or veneer 
redryers.

                     General Compliance Requirements



Sec. 63.2250  What are the general requirements?

    (a) You must be in compliance with the compliance options, operating 
requirements, and the work practice requirements in this subpart at all 
times, except during periods of process unit or control device startup, 
shutdown, and malfunction; prior to process unit initial startup; and 
during the routine

[[Page 245]]

control device maintenance exemption specified in Sec. 63.2251. The 
compliance options, operating requirements, and work practice 
requirements do not apply during times when the process unit(s) subject 
to the compliance options, operating requirements, and work practice 
requirements are not operating, or during periods of startup, shutdown, 
and malfunction. Startup and shutdown periods must not exceed the 
minimum amount of time necessary for these events.
    (b) You must always operate and maintain your affected source, 
including air pollution control and monitoring equipment, according to 
the provisions in Sec. 63.6(e)(1)(i).
    (c) You must develop a written SSMP according to the provisions in 
Sec. 63.6(e)(3).
    (d) Shutoff of direct-fired burners resulting from partial and full 
production stoppages of direct-fired softwood veneer dryers or over-
temperature events shall be deemed shutdowns and not malfunctions. 
Lighting or re-lighting any one or all gas burners in direct-fired 
softwood veneer dryers shall be deemed startups and not malfunctions.

FR 20463, Apr. 20, 2006]



Sec. 63.2251  What are the requirements for the routine control device
maintenance exemption?

    (a) You may request a routine control device maintenance exemption 
from the EPA Administrator for routine maintenance events such as 
control device bakeouts, washouts, media replacement, and replacement of 
corroded parts. Your request must justify the need for the routine 
maintenance on the control device and the time required to accomplish 
the maintenance activities, describe the maintenance activities and the 
frequency of the maintenance activities, explain why the maintenance 
cannot be accomplished during process shutdowns, describe how you plan 
to make reasonable efforts to minimize emissions during the maintenance, 
and provide any other documentation required by the EPA Administrator.
    (b) The routine control device maintenance exemption must not exceed 
the percentages of process unit operating uptime in paragraphs (b)(1) 
and (2) of this section.
    (1) If the control device is used to control a green rotary dryer, 
tube dryer, rotary strand dryer, or pressurized refiner, then the 
routine control device maintenance exemption must not exceed 3 percent 
of annual operating uptime for each process unit controlled.
    (2) If the control device is used to control a softwood veneer 
dryer, reconstituted wood product press, reconstituted wood product 
board cooler, hardboard oven, press predryer, conveyor strand dryer, or 
fiberboard mat dryer, then the routine control device maintenance 
exemption must not exceed 0.5 percent of annual operating uptime for 
each process unit controlled.
    (3) If the control device is used to control a combination of 
equipment listed in both paragraphs (b)(1) and (2) of this section, such 
as a tube dryer and a reconstituted wood product press, then the routine 
control device maintenance exemption must not exceed 3 percent of annual 
operating uptime for each process unit controlled.
    (c) The request for the routine control device maintenance 
exemption, if approved by the EPA Administrator, must be IBR in and 
attached to the affected source's title V permit.
    (d) The compliance options and operating requirements do not apply 
during times when control device maintenance covered under your approved 
routine control device maintenance exemption is performed. You must 
minimize emissions to the greatest extent possible during these routine 
control device maintenance periods.
    (e) To the extent practical, startup and shutdown of emission 
control systems must be scheduled during times when process equipment is 
also shut down.



Sec. 63.2252  What are the requirements for process units that have
no control or work practice requirements?

    For process units not subject to the compliance options or work 
practice requirements specified in Sec. 63.2240 (including, but not 
limited to, lumber kilns), you are not required to comply

[[Page 246]]

with the compliance options, work practice requirements, performance 
testing, monitoring, SSM plans, and recordkeeping or reporting 
requirements of this subpart, or any other requirements in subpart A of 
this part, except for the initial notification requirements in Sec. 
63.9(b).

[71 FR 8372, Feb. 16, 2006]

                     Initial Compliance Requirements



Sec. 63.2260  How do I demonstrate initial compliance with the 
compliance options, operating requirements, and work practice
requirements?

    (a) To demonstrate initial compliance with the compliance options 
and operating requirements, you must conduct performance tests and 
establish each site-specific operating requirement in Table 2 to this 
subpart according to the requirements in Sec. 63.2262 and Table 4 to 
this subpart. Combustion units that accept process exhausts into the 
flame zone are exempt from the initial performance testing and operating 
requirements for thermal oxidizers.
    (b) You must demonstrate initial compliance with each compliance 
option, operating requirement, and work practice requirement that 
applies to you according to Tables 5 and 6 to this subpart and according 
to Sec. Sec. 63.2260 through 63.2269 of this subpart.
    (c) You must submit the Notification of Compliance Status containing 
the results of the initial compliance demonstration according to the 
requirements in Sec. 63.2280(d).



Sec. 63.2261  By what date must I conduct performance tests or other
initial compliance demonstrations?

    (a) You must conduct performance tests upon initial startup or no 
later than 180 calendar days after the compliance date that is specified 
for your source in Sec. 63.2233 and according to Sec. 63.7(a)(2), 
whichever is later.
    (b) You must conduct initial compliance demonstrations that do not 
require performance tests upon initial startup or no later than 30 
calendar days after the compliance date that is specified for your 
source in Sec. 63.2233, whichever is later.



Sec. 63.2262  How do I conduct performance tests and establish
operating requirements?

    (a) You must conduct each performance test according to the 
requirements in Sec. 63.7(e)(1), the requirements in paragraphs (b) 
through (o) of this section, and according to the methods specified in 
Table 4 to this subpart.
    (b) Periods when performance tests must be conducted. (1) You must 
not conduct performance tests during periods of startup, shutdown, or 
malfunction, as specified in Sec. 63.7(e)(1).
    (2) You must test under representative operating conditions as 
defined in Sec. 63.2292. You must describe representative operating 
conditions in your performance test report for the process and control 
systems and explain why they are representative.
    (c) Number of test runs. You must conduct three separate test runs 
for each performance test required in this section as specified in Sec. 
63.7(e)(3). Each test run must last at least 1 hour except for: testing 
of a temporary total enclosure (TTE) conducted using Methods 204A 
through 204F of 40 CFR part 51, appendix M, which require three separate 
test runs of at least 3 hours each; and testing of an enclosure 
conducted using the alternative tracer gas method in appendix A to this 
subpart, which requires a minimum of three separate runs of at least 20 
minutes each.
    (d) Location of sampling sites. (1) Sampling sites must be located 
at the inlet (if emission reduction testing or documentation of inlet 
methanol or formaldehyde concentration is required) and outlet of the 
control device (defined in Sec. 63.2292) and prior to any releases to 
the atmosphere. For control sequences with wet control devices (defined 
in Sec. 63.2292) followed by control devices (defined in Sec. 
63.2292), sampling sites may be located at the inlet and outlet of the 
control sequence and prior to any releases to the atmosphere.
    (2) Sampling sites for process units meeting compliance options 
without a control device must be located prior to any releases to the 
atmosphere. Facilities demonstrating compliance with a production-based 
compliance option for

[[Page 247]]

a process unit equipped with a wet control device must locate sampling 
sites prior to the wet control device.
    (e) Collection of monitoring data. You must collect operating 
parameter monitoring system or continuous emissions monitoring system 
(CEMS) data at least every 15 minutes during the entire performance test 
and determine the parameter or concentration value for the operating 
requirement during the performance test using the methods specified in 
paragraphs (k) through (o) of this section.
    (f) Collection of production data. To comply with any of the 
production-based compliance options, you must measure and record the 
process unit throughput during each performance test.
    (g) Nondetect data. (1) Except as specified in paragraph (g)(2) of 
this section, all nondetect data (Sec. 63.2292) must be treated as one-
half of the method detection limit when determining total HAP, 
formaldehyde, methanol, or total hydrocarbon (THC) emission rates.
    (2) When showing compliance with the production-based compliance 
options in Table 1A to this subpart, you may treat emissions of an 
individual HAP as zero if all three of the performance test runs result 
in a nondetect measurement, and the method detection limit is less than 
or equal to 1 parts per million by volume, dry basis (ppmvd). Otherwise, 
nondetect data for individual HAP must be treated as one-half of the 
method detection limit.
    (h) Calculation of percent reduction across a control system. When 
determining the control system efficiency for any control system 
included in your emissions averaging plan (not to exceed 90 percent) and 
when complying with any of the compliance options based on percent 
reduction across a control system in Table 1B to this subpart, as part 
of the performance test, you must calculate the percent reduction using 
Equation 1 of this section:
[GRAPHIC] [TIFF OMITTED] TR72AD04.003

Where:

PR = percent reduction, percent;
CE = capture efficiency, percent (determined for reconstituted wood 
          product presses and board coolers as required in Table 4 to 
          this subpart);
ERin = emission rate of total HAP (calculated as the sum of 
          the emission rates of acetaldehyde, acrolein, formaldehyde, 
          methanol, phenol, and propionaldehyde), THC, formaldehyde, or 
          methanol in the inlet vent stream of the control device, 
          pounds per hour;
ERout = emission rate of total HAP (calculated as the sum of 
          the emission rates of acetaldehyde, acrolein, formaldehyde, 
          methanol, phenol, and propionaldehyde), THC, formaldehyde, or 
          methanol in the outlet vent stream of the control device, 
          pounds per hour.

    (i) Calculation of mass per unit production. To comply with any of 
the production-based compliance options in Table 1A to this subpart, you 
must calculate your mass per unit production emissions for each 
performance test run using Equation 2 of this section:
[GRAPHIC] [TIFF OMITTED] TR72AD04.004

Where:

MP = mass per unit production, pounds per oven dried ton OR pounds per 
          thousand square feet on a specified thickness basis (see 
          paragraph (j) of this section if you need to convert from one 
          thickness basis to another);
ERHAP = emission rate of total HAP (calculated as the sum of 
          the emission rates of acetaldehyde, acrolein, formaldehyde, 
          methanol, phenol, and propionaldehyde) in the stack, pounds 
          per hour;
P = process unit production rate (throughput), oven dried tons per hour 
          OR thousand square feet per hour on a specified thickness 
          basis;
CE = capture efficiency, percent (determined for reconstituted wood 
          product presses and board coolers as required in Table 4 to 
          this subpart).

    (j) Thickness basis conversion. Use Equation 3 of this section to 
convert from one thickness basis to another:
[GRAPHIC] [TIFF OMITTED] TR72AD04.005

Where:

MSFA = thousand square feet on an A-inch basis;
MSFB = thousand square feet on a B-inch basis;
A = old thickness you are converting from, inches;
B = new thickness you are converting to, inches.


[[Page 248]]


    (k) Establishing thermal oxidizer operating requirements. If you 
operate a thermal oxidizer, you must establish your thermal oxidizer 
operating parameters according to paragraphs (k)(1) through (3) of this 
section.
    (1) During the performance test, you must continuously monitor the 
firebox temperature during each of the required 1-hour test runs. For 
regenerative thermal oxidizers, you may measure the temperature in 
multiple locations (e.g., one location per burner) in the combustion 
chamber and calculate the average of the temperature measurements prior 
to reducing the temperature data to 15-minute averages for purposes of 
establishing your minimum firebox temperature. The minimum firebox 
temperature must then be established as the average of the three minimum 
15-minute firebox temperatures monitored during the three test runs. 
Multiple three-run performance tests may be conducted to establish a 
range of parameter values under different operating conditions.
    (2) You may establish a different minimum firebox temperature for 
your thermal oxidizer by submitting the notification specified in Sec. 
63.2280(g) and conducting a repeat performance test as specified in 
paragraph (k)(1) of this section that demonstrates compliance with the 
applicable compliance options of this subpart.
    (3) If your thermal oxidizer is a combustion unit that accepts 
process exhaust into the flame zone, then you are exempt from the 
performance testing and monitoring requirements specified in paragraphs 
(k)(1) and (2) of this section. To demonstrate initial compliance, you 
must submit documentation with your Notification of Compliance Status 
showing that process exhausts controlled by the combustion unit enter 
into the flame zone.
    (l) Establishing catalytic oxidizer operating requirements. If you 
operate a catalytic oxidizer, you must establish your catalytic oxidizer 
operating parameters according to paragraphs (l)(1) and (2) of this 
section.
    (1) During the performance test, you must continuously monitor 
during the required 1-hour test runs either the temperature at the inlet 
to each catalyst bed or the temperature in the combustion chamber. For 
regenerative catalytic oxidizers, you must calculate the average of the 
temperature measurements from each catalyst bed inlet or within the 
combustion chamber prior to reducing the temperature data to 15-minute 
averages for purposes of establishing your minimum catalytic oxidizer 
temperature. The minimum catalytic oxidizer temperature must then be 
established as the average of the three minimum 15-minute temperatures 
monitored during the three test runs. Multiple three-run performance 
tests may be conducted to establish a range of parameter values under 
different operating conditions.
    (2) You may establish a different minimum catalytic oxidizer 
temperature by submitting the notification specified in Sec. 63.2280(g) 
and conducting a repeat performance test as specified in paragraphs 
(l)(1) and (2) of this section that demonstrates compliance with the 
applicable compliance options of this subpart.
    (m) Establishing biofilter operating requirements. If you operate a 
biofilter, you must establish your biofilter operating requirements 
according to paragraphs (m)(1) through (3) of this section.
    (1) During the performance test, you must continuously monitor the 
biofilter bed temperature during each of the required 1-hour test runs. 
To monitor biofilter bed temperature, you may use multiple thermocouples 
in representative locations throughout the biofilter bed and calculate 
the average biofilter bed temperature across these thermocouples prior 
to reducing the temperature data to 15-minute averages for purposes of 
establishing biofilter bed temperature limits. The biofilter bed 
temperature range must be established as the minimum and maximum 15-
minute biofilter bed temperatures monitored during the three test runs. 
You may base your biofilter bed temperature range on values recorded 
during previous performance tests provided that the data used to 
establish the temperature ranges have been obtained using the test 
methods required in this subpart. If you use data from previous 
performance tests, you must certify that the biofilter and associated 
process unit(s) have not been modified

[[Page 249]]

subsequent to the date of the performance tests. Replacement of the 
biofilter media with the same type of material is not considered a 
modification of the biofilter for purposes of this section.
    (2) For a new biofilter installation, you will be allowed up to 180 
days following the compliance date or 180 days following initial startup 
of the biofilter to complete the requirements in paragraph (m)(1) of 
this section.
    (3) You may expand your biofilter bed temperature operating range by 
submitting the notification specified in Sec. 63.2280(g) and conducting 
a repeat performance test as specified in paragraph (m)(1) of this 
section that demonstrates compliance with the applicable compliance 
options of this subpart.
    (n) Establishing operating requirements for process units meeting 
compliance options without a control device. If you operate a process 
unit that meets a compliance option in Table 1A to this subpart, or is a 
process unit that generates debits in an emissions average without the 
use of a control device, you must establish your process unit operating 
parameters according to paragraphs (n)(1) through (2) of this section.
    (1) During the performance test, you must identify and document the 
process unit controlling parameter(s) that affect total HAP emissions 
during the three-run performance test. The controlling parameters you 
identify must coincide with the representative operating conditions you 
describe according to Sec. 63.2262(b)(2). For each parameter, you must 
specify appropriate monitoring methods, monitoring frequencies, and for 
continuously monitored parameters, averaging times not to exceed 24 
hours. The operating limit for each controlling parameter must then be 
established as the minimum, maximum, range, or average (as appropriate 
depending on the parameter) recorded during the performance test. 
Multiple three-run performance tests may be conducted to establish a 
range of parameter values under different operating conditions.
    (2) You may establish different controlling parameter limits for 
your process unit by submitting the notification specified in Sec. 
63.2280(g) and conducting a repeat performance test as specified in 
paragraph (n)(1) of this section that demonstrates compliance with the 
compliance options in Table 1A to this subpart or is used to establish 
emission averaging debits for an uncontrolled process unit.
    (o) Establishing operating requirements using THC CEMS. If you 
choose to meet the operating requirements by monitoring THC 
concentration instead of monitoring control device or process operating 
parameters, you must establish your THC concentration operating 
requirement according to paragraphs (o)(1) through (2) of this section.
    (1) During the performance test, you must continuously monitor THC 
concentration using your CEMS during each of the required 1-hour test 
runs. The maximum THC concentration must then be established as the 
average of the three maximum 15-minute THC concentrations monitored 
during the three test runs. Multiple three-run performance tests may be 
conducted to establish a range of THC concentration values under 
different operating conditions.
    (2) You may establish a different maximum THC concentration by 
submitting the notification specified in Sec. 63.2280(g) and conducting 
a repeat performance test as specified in paragraph (o)(1) of this 
section that demonstrates compliance with the compliance options in 
Tables 1A and 1B to this subpart.

than or equal to 25 percent (by weight, dry basis). In addition, submit 
with the Notification of Compliance Status a signed statement by a 
responsible official that certifies with truth, accuracy, and 
completeness that the veneer redryer will dry veneer with a moisture 
content less than 25 percent (by weight, dry basis) in the future.



Sec. 63.2267  Initial compliance demonstration for a reconstituted
wood product press or board cooler.

    If you operate a reconstituted wood product press at a new or 
existing affected source or a reconstituted wood product board cooler at 
a new affected source, then you must either use a wood products 
enclosure as defined in Sec. 63.2292 or measure the capture efficiency 
of the capture device for the press or board cooler using Methods 204 
and 204A through 204F of 40 CFR part 51, appendix M (as appropriate), or 
using the alternative tracer gas method contained in appendix A to this 
subpart. You must submit documentation that the wood products enclosure

device.

    If you use a wet control device as the sole means of reducing HAP 
emissions, you must develop and implement a plan for review and approval 
to address how organic HAP captured in the wastewater from the wet 
control device is contained or destroyed to minimize re-release to the 
atmosphere such that the desired emissions reductions are obtained. You 
must submit the plan with your Notification of Compliance Status.



Sec. 63.2269  What are my monitoring installation, operation,
and maintenance requirements?

    (a) General continuous parameter monitoring requirements. You must 
install, operate, and maintain each continuous parameter monitoring 
system (CPMS) according to paragraphs (a)(1) through (3) of this 
section.
    (1) The CPMS must be capable of completing a minimum of one cycle of

                   Continuous Compliance Requirements



Sec. 63.2270  How do I monitor and collect data to demonstrate 
continuous compliance?

    (a) You must monitor and collect data according to this section.
    (b) Except for, as appropriate, monitor malfunctions, associated 
repairs, and required quality assurance or control activities 
(including, as applicable, calibration checks and required zero and span 
adjustments), you must conduct all monitoring in continuous operation at 
all times that the process unit is operating. For purposes of 
calculating data averages, you must not use data recorded during 
monitoring malfunctions, associated repairs, out-of-control periods, or 
required quality assurance or control activities. You must use all the 
data collected during all other periods in assessing compliance. A 
monitoring malfunction is any sudden, infrequent, not reasonably 
preventable failure of the monitoring to provide valid data. Monitoring 
failures that are caused in part by poor maintenance or careless 
operation are not malfunctions. Any period for which the monitoring 
system is out-of-control and data are not available for required 
calculations constitutes a deviation from the monitoring requirements.
    (c) You may not use data recorded during monitoring malfunctions, 
associated repairs, and required quality assurance or control 
activities; data recorded during periods of startup, shutdown, and 
malfunction; or data recorded during periods of control device downtime 
covered in any approved routine control device maintenance exemption in 
data averages and calculations used to report emission or operating 
levels, nor may such data be used in fulfilling a minimum data 
availability requirement, if applicable. You must use all the data 
collected during all other periods in assessing the operation of the 
control system.
    (d) Except as provided in paragraph (e) of this section, determine 
the 3-hour block average of all recorded readings, calculated after 
every 3 hours of operation as the average of the evenly spaced recorded 
readings in the previous 3 operating hours (excluding periods described 
in paragraphs (b) and (c) of this section).
    (e) For dry rotary dryer and veneer redryer wood moisture 
monitoring, dry rotary dryer temperature monitoring, biofilter bed 
temperature monitoring, and biofilter outlet THC monitoring, determine 
the 24-hour block average of all recorded readings, calculated after 
every 24 hours of operation as the average of the evenly spaced recorded 
readings in the previous 24 operating hours (excluding periods described 
in paragraphs (b) and (c) of this section).
    (f) To calculate the data averages for each 3-hour or 24-hour 
averaging period, you must have at least 75 percent of the required 
recorded readings for that period using only recorded readings that are 
based on valid data (i.e., not from periods described in paragraphs (b) 
and (c) of this section).

[[Page 253]]



Sec. 63.2271  How do I demonstrate continuous compliance with the 
compliance options, operating requirements, and work practice

(rubbing or grinding) the wood material into fibers. Pressurized 
refiners are operated with continuous infeed and outfeed of wood 
material and maintain elevated internal pressures (i.e., there is no 
pressure release) throughout the preheating and refining process. A 
pressurized refiner is a process unit.
    Primary tube dryer means a single-stage tube dryer or the first 
stage of a multi-stage tube dryer. Tube dryer stages are separated by 
vents for removal of moist gases between stages (e.g., a product cyclone 
at the end of a single-stage dryer or between the first and second 
stages of a multi-stage tube dryer). The first stage of a multi-stage 
tube dryer is used to remove the majority of the moisture from the wood 
furnish (compared to the moisture reduction in subsequent stages of the 
tube dryer). Blow-lines used to apply resin are considered part of the 
primary tube dryer. A primary tube dryer is a process unit.
    Process unit means equipment classified according to its function 
such as a blender, dryer, press, former, or board cooler.
    Reconstituted wood product board cooler means a piece of equipment 
designed to reduce the temperature of a board by means of forced air or

integrated into or following hardboard bake ovens or humidifiers. A 
reconstituted wood product board cooler is a process unit.
    Reconstituted wood product press means a press, including (if 
applicable) the press unloader, that presses a resinated mat of wood 
fibers, particles, or strands between hot platens or hot rollers to 
compact and set the mat into a panel by simultaneous application of heat 
and pressure. Reconstituted wood product presses are used in the 
manufacture of hardboard, medium density fiberboard, particleboard, and 
oriented strandboard. Extruders are not considered to be reconstituted 
wood product presses. A reconstituted wood product press is a process 
unit.
    Representative operating conditions means operation of a process 
unit during performance testing under the conditions that the process 
unit will typically be operating in the future, including use of a 
representative range of materials (e.g., wood material of a typical 
species mix and moisture content or typical resin formulation) and 
representative operating temperature range.
    Resin means the synthetic adhesive (including glue) or natural 
binder, including additives, used to bond wood or other cellulosic 
materials together to produce plywood and composite wood products.
    Responsible official means responsible official as defined in 40 CFR 
70.2 and 40 CFR 71.2.

    Rotary strand dryer means a rotary dryer operated by applying heat 
and used to reduce the moisture of wood strands used in the manufacture 
of oriented strandboard, laminated strand lumber, or other wood strand-
based products. A rotary strand dryer is a process unit.
    Secondary tube dryer means the second stage and subsequent stages 
following the primary stage of a multi-stage tube dryer. Secondary tube 
dryers, also referred to as relay dryers, operate at lower temperatures 
than the primary tube dryer they follow. Secondary tube dryers are used 
to remove only a small amount of the furnish moisture compared to the 
furnish moisture reduction across the primary tube dryer. A secondary 
tube dryer is a process unit.
    Softwood means the wood of a coniferous tree. Examples of softwoods 
include, but are not limited to, Southern yellow pine, Douglas fir, and 
White spruce.
    Softwood veneer dryer means a dryer that removes excess moisture 
from veneer by conveying the veneer through a heated medium, generally 
on rollers, belts, cables, or wire mesh. Softwood veneer dryers are used 
to dry veneer with greater than or equal to 30 percent softwood species 
on an annual volume basis. Veneer kilns that operate as batch units, 
veneer dryers heated by radio frequency or microwaves that are used to 
redry veneer, and veneer redryers (defined elsewhere in this section) 
that are heated by conventional means are not considered to be softwood 
veneer dryers. A softwood veneer dryer is a process unit.
    Startup means bringing equipment online and starting the production 
process.
    Startup, initial means the first time equipment is put into 
operation. Initial startup does not include operation solely for testing 
equipment. Initial startup does not include subsequent startups (as 
defined in this section) following malfunction or shutdowns or following 
changes in product or between batch operations. Initial startup does not 
include startup of equipment that occurred when the source was an area 
source.
    Startup, shutdown, and malfunction plan (SSMP) means a plan 
developed according to the provisions of Sec. 63.6(e)(3).

exhaust gas from a process unit. Thermal oxidizers include regenerative 
thermal oxidizers and combustion units.
    Total hazardous air pollutant emissions means, for purposes of this 
subpart, the sum of the emissions of the following six compounds: 
acetaldehyde, acrolein, formaldehyde, methanol, phenol, and 
propionaldehyde.
    Tube dryer means a single-stage or multi-stage dryer operated by 
applying heat to reduce the moisture of wood fibers or particles as they 
are conveyed (usually pneumatically) through the dryer. Resin may or may 
not be applied to the wood material before it enters the tube dryer. 
Tube dryers do not include pneumatic fiber transport systems that use 
temperature and humidity conditioned pneumatic system supply air in 
order to prevent cooling of the wood fiber as it is moved through the 
process. A tube dryer is a process unit.
    Veneer means thin sheets of wood peeled or sliced from logs for use 
in the manufacture of wood products such as plywood, laminated veneer 
lumber, or other products.
    Veneer redryer means a dryer heated by conventional means, such as 
direct wood-fired, direct-gas-fired, or steam heated, that is used to 
redry veneer that has been previously dried. Because the veneer dried in 
a veneer redryer has been previously dried, the inlet moisture content 
of the veneer entering the redryer is less than 25 percent (by weight, 
dry basis). Batch units used to redry veneer (such as redry cookers)

[[Page 263]]

are not considered to be veneer redryers. A veneer redryer is a process 
unit.
    Wet control device means any equipment that uses water as a means of 
collecting an air pollutant. Wet control devices include scrubbers, wet 
electrostatic precipitators, and electrified filter beds. Wet control 
devices do not include biofilters or other equipment that destroys or 
degrades HAP.

section formed by bonding (with resin) wood or laminated veneer lumber 
flanges onto a web cut from a panel such as plywood or oriented 
strandboard.
    Wood products enclosure means a permanently installed containment 
that was designed to meet the following physical design criteria:
    (1) Any natural draft opening shall be at least four equivalent 
opening diameters from each HAP-emitting point, except for where board 
enters and exits the enclosure, unless otherwise specified by the EPA 
Administrator.
    (2) The total area of all natural draft openings shall not exceed 5 
percent of the surface area of the enclosure's four walls, floor, and 
ceiling.
    (3) The average facial velocity of air through all natural draft 
openings shall be at least 3,600 meters per hour (200 feet per minute). 
The direction of airflow through all natural draft openings shall be 
into the enclosure.
    (4) All access doors and windows whose areas are not included in 
item 2 of this definition and are not included in the calculation of 
facial velocity in item 3 of this definition shall be closed during 
routine operation of the process.
    (5) The enclosure is designed and maintained to capture all 
emissions for discharge through a control device.
    Work practice requirement means any design, equipment, work 
practice, or operational standard, or combination thereof, that is 
promulgated pursuant to section 112(h) of the CAA.

  Sec. Appendix A to Subpart DDDD of Part 63--Alternative Procedure To 
 Determine Capture Efficiency From Enclosures Around Hot Presses in the 
 Plywood and Composite Wood Products Industry Using Sulfur Hexafluoride 
                               Tracer Gas

                        1.0 Scope and Application

    This procedure has been developed specifically for the rule for the 
plywood and composite wood products (PCWP) industry and is used to 
determine the capture efficiency of a partial hot press enclosure in 
that industry. This procedure is applicable for the determination of 
capture efficiency for enclosures around hot presses and is an 
alternative to the construction of temporary total enclosures (TTE). 
Sulfur hexafluoride (SF6) is used as a tracer gas (other 
tracer gases may be used if approved by the EPA Administrator). This gas 
is not indigenous to the ambient atmosphere and is nonreactive.
    This procedure uses infrared spectrometry (IR) as the analytical 
technique. When the infrared spectrometer used is a Fourier-Transform 
Infrared spectrometer (FTIR), an alternate instrument calibration 
procedure may be used; the alternate calibration procedure is the 
calibration transfer standard (CTS) procedure of EPA Method 320 
(appendix A to 40 CFR part 63). Other analytical

[[Page 275]]

techniques which are capable of equivalent Method Performance (Section 
13.0) also may be used. Specifically, gas chromatography with electron 
capture detection (GC/ECD) is an applicable technique for analysis of 
SF6.

                          2.0 Summary of Method

    A constant mass flow rate of SF6 tracer gas is released 
through manifolds at multiple locations within the enclosure to mimic 
the release of hazardous air pollutants during the press process. This 
test method requires a minimum of three SF6 injection points 
(two at the press unloader and one at the press) and provides details 
about considerations for locating the injection points. A GC/ECD is used 
to measure the concentration of SF6 at the inlet duct to the 
control device (outlet duct from enclosure). Simultaneously, EPA Method 
2 (appendix A to 40 CFR part 60) is used to measure the flow rate at the 
inlet duct to the control device. The concentration and flow rate 
measurements are used to calculate the mass emission rate of 
SF6 at the control device inlet. Through calculation of the 
mass of SF6 released through the manifolds and the mass of 
SF6 measured at the inlet to the control device, the capture 
efficiency of the enclosure is calculated.
    In addition, optional samples of the ambient air may be taken at 
locations around the perimeter of the enclosure to quantify the ambient 
concentration of SF6 and to identify those areas of the 
enclosure that may be performing less efficiently; these samples would 
be taken using disposable syringes and would be analyzed using a GC/ECD.
    Finally, in addition to the requirements specified in this 
procedure, the data quality objectives (DQO) or lower confidence limit 
(LCL) criteria specified in appendix A to 40 CFR part 63, subpart KK, 
Data Quality Objective and Lower Confidence Limit Approaches for 
Alternative Capture Efficiency Protocols and Test Methods, must also be 
satisfied. A minimum of three test runs are required for this procedure; 
however, additional test runs may be required based on the results of 
the DQO or LCL analysis.

                             3.0 Definitions

    3.1 Capture efficiency (CE). The weight per unit time of 
SF6 entering the control device divided by the weight per 
unit time of SF6 released through manifolds at multiple 
locations within the enclosure.
    3.2 Control device (CD). The equipment used to reduce, by 
destruction or removal, press exhaust air pollutants prior to discharge 
to the ambient air.
    3.3 Control/destruction efficiency (DE). The volatile organic 
compound or HAP removal efficiency of the control device.
    3.4 Data Quality Objective (DQO) Approach. A statistical procedure 
to determine the precision of the data from a test series and to qualify 
the data in the determination of capture efficiency for compliance 
purposes. If the results of the DQO analysis of the initial three test 
runs do not satisfy the DQO criterion, the LCL approach can be used or 
additional test runs must be conducted. If additional test runs are 
conducted, then the DQO or LCL analysis is conducted using the data from 
both the initial test runs and all additional test runs.
    3.5 Lower Confidence Limit (LCL) Approach. An alternative 
statistical procedure that can be used to qualify data in the 
determination of capture efficiency for compliance purposes. If the 
results of the LCL approach produce a CE that is too low for 
demonstrating compliance, then additional test runs must be conducted 
until the LCL or DQO is met. As with the DQO, data from all valid test 
runs must be used in the calculation.
    3.6 Minimum Measurement Level (MML). The minimum tracer gas 
concentration expected to be measured during the test series. This value 
is selected by the tester based on the capabilities of the IR 
spectrometer (or GC/ECD) and the other known or measured parameters of 
the hot press enclosure to be tested. The selected MML must be above the 
low-level calibration standard and preferably below the mid-level 
calibration standard.
    3.7 Method 204. The U.S. EPA Method 204, ``Criteria For and 
Verification of a Permanent or Temporary Total Enclosure'' (40 CFR part 
51, appendix M).
    3.8 Method 205. The U.S. EPA Method 205, ``Verification of Gas 
Dilution Systems for Field Instrument Calibrations'' (40 CFR part 51, 
appendix M).
    3.9 Method 320. The U.S. EPA Method 320, ``Measurement of Vapor 
Phase Organic and Inorganic Emissions by Extractive Fourier Transform 
Infrared (FTIR) Spectroscopy'' (40 CFR part 63, appendix A).
    3.10 Overall capture and control efficiency (CCE). The collection 
and control/destruction efficiency of both the PPE and CD combined. The 
CCE is calculated as the product of the CE and DE.
    3.11 Partial press enclosure (PPE). The physical barrier that 
``partially'' encloses the press equipment, captures a significant 
amount of the associated emissions, and transports those emissions to 
the CD.
    3.12 Test series. A minimum of three test runs or, when more than 
three runs are conducted, all of the test runs conducted.

                            4.0 Interferences

    There are no known interferences.

                               5.0 Safety

    Sulfur hexafluoride is a colorless, odorless, nonflammable liquefied 
gas. It is stable and nonreactive and, because it is noncorrosive,

[[Page 276]]

most structural materials are compatible with it. The Occupational 
Safety and Health Administration Permissible Emission Limit-Time 
Weighted Average (PEL-TWA) and Threshold Limit Value-Time Weighted 
Average (TLV-TWA) concentrations are 1,000 parts per million. Sulfur 
hexafluoride is an asphyxiant. Exposure to an oxygen-deficient 
atmosphere (less than 19.5 percent oxygen) may cause dizziness, 
drowsiness, nausea, vomiting, excess salivation, diminished mental 
alertness, loss of consciousness, and death. Exposure to atmospheres 
containing less than 12 percent oxygen will bring about unconsciousness 
without warning and so quickly that the individuals cannot help 
themselves. Contact with liquid or cold vapor may cause frostbite. Avoid 
breathing sulfur hexafluoride gas. Self-contained breathing apparatus 
may be required by rescue workers. Sulfur hexafluoride is not listed as 
a carcinogen or a potential carcinogen.

                       6.0 Equipment and Supplies

    This method requires equipment and supplies for: (a) the injection 
of tracer gas into the enclosure, (b) the measurement of the tracer gas 
concentration in the exhaust gas entering the control device, and (c) 
the measurement of the volumetric flow rate of the exhaust gas entering 
the control device. In addition, the requisite equipment needed for EPA 
Methods 1-4 in appendix A to 40 CFR part 60 will be required. Equipment 
and supplies for optional ambient air sampling are discussed in Section 
8.6.
    6.1 Tracer Gas Injection.
    6.1.1 Manifolds. This method requires the use of tracer gas supply 
cylinder(s) along with the appropriate flow control elements. Figure 1 
shows a schematic drawing of the injection system showing potential 
locations for the tracer gas manifolds. Figure 2 shows a schematic 
drawing of the recommended configuration of the injection manifold. 
Three tracer gas discharge manifolds are required at a minimum.
    6.1.2 Flow Control Meter. Flow control and measurement meter for 
measuring the quantity of tracer gas injected. A mass flow, volumetric 
flow, or critical orifice control meter can be used for this method. The 
meter must be accurate to within 5 percent at the 
flow rate used. This means that the flow meter must be calibrated 
against a primary standard for flow measurement at the appropriate flow 
rate.
    6.2 Measurement of Tracer Gas Concentration.
    6.2.1 Sampling Probes. Use Pyrex or stainless steel sampling probes 
of sufficient length to reach the traverse points calculated according 
to EPA Method 1 (appendix A to 40 CFR part 60).
    6.2.2 Sampling Line. Use a heated Teflon sampling line to transport 
the sample to the analytical instrument.
    6.2.3 Sampling Pump. Use a sampling pump capable of extracting 
sufficient sample from the duct and transporting to the analytical 
instrument.
    6.2.4 Sample Conditioning System. Use a particulate filter 
sufficient to protect the sampling pump and analytical instrument. At 
the discretion of the tester and depending on the equipment used and the 
moisture content of the exhaust gas, it may be necessary to further 
condition the sample by removing moisture using a condenser.
    6.2.5 Analytical Instrument. Use one of the following analytical 
instruments.
    6.2.5.1 Spectrometer. Use an infrared spectrometer designed to 
measuring SF6 tracer gas and capable of meeting or exceeding 
the specifications of this procedure. An FTIR meeting the specifications 
of Method 320 in appendix A to 40 CFR part 63 may be used.
    6.2.5.2 GC/ECD. Use a GC/ECD designed to measure SF6 
tracer gas and capable of meeting or exceeding the specifications of 
this procedure.
    6.2.6 Recorder. At a minimum, use a recorder with linear strip 
chart. An automated data acquisition system (DAS) is recommended.
    6.3 Exhaust Gas Flow Rate Measurement. Use equipment specified for 
EPA Methods 2, 3, and 4 in appendix A to 40 CFR part 60 for measuring 
flow rate of exhaust gas at the inlet to the control device.

                       7.0 Reagents and Standards

    7.1 Tracer Gas. Use SF6 as the tracer gas. The 
manufacturer of the SF6 tracer gas should provide a 
recommended shelf life for the tracer gas cylinder over which the 
concentration does not change more than 2 percent 
from the certified value. A gas mixture of SF6 diluted with 
nitrogen should be used; based on experience and calculations, pure 
SF6 gas is not necessary to conduct tracer gas testing. 
Select a concentration and flow rate that is appropriate for the 
analytical instrument's detection limit, the MML, and the exhaust gas 
flow rate from the enclosure (see section 8.1.1). You may use a tracer 
gas other than SF6 with the prior approval of the EPA 
Administrator. If you use an approved tracer gas other than 
SF6, all references to SF6 in this protocol 
instead refer to the approved tracer gas.
    7.2 Calibration Gases. The SF6 calibration gases required 
will be dependent on the selected MML and the appropriate span selected 
for the test. Commercial cylinder gases certified by the manufacturer to 
be accurate to within 1 percent of the certified label value are 
preferable, although cylinder gases certified by the manufacturer to 2 
percent accuracy are allowed. Additionally, the manufacturer of the 
SF6 calibration gases should provide a recommended shelf life 
for each calibration gas cylinder over which the concentration does not 
change more than 2

[[Page 277]]

percent from the certified value. Another option allowed by this method 
is for the tester to obtain high concentration certified cylinder gases 
and then use a dilution system meeting the requirements of EPA Method 
205, 40 CFR part 51, appendix M, to make multi-level calibration gas 
standards. Low-level, mid-level, and high-level calibration gases will 
be required. The MML must be above the low-level standard, the high-
level standard must be no more than four times the low-level standard, 
and the mid-level standard must be approximately halfway between the 
high- and low-level standards. See section 12.1 for an example 
calculation of this procedure.

    Note: If using an FTIR as the analytical instrument, the tester has 
the option of following the CTS procedures of Method 320 in appendix A 
to 40 CFR part 63; the calibration standards (and procedures) specified 
in Method 320 may be used in lieu of the calibration standards and 
procedures in this protocol.

    7.2.1 Zero Gas. High purity nitrogen.
    7.2.2 Low-Level Calibration Gas. An SF6 calibration gas 
in nitrogen with a concentration equivalent to 20 to 30 percent of the 
applicable span value.
    7.2.3 Mid-Level Calibration Gas. An SF6 calibration gas 
in nitrogen with a concentration equivalent to 45 to 55 percent of the 
applicable span value.
    7.2.4 High-Level Calibration Gas. An SF6 calibration gas 
in nitrogen with a concentration equivalent to 80 to 90 percent of the 
applicable span value.

       8.0 Sample Collection, Preservation, Storage, and Transport

    8.1 Test Design.
    8.1.1 Determination of Minimum Tracer Gas Flow Rate.
    8.1.1.1 Determine (via design calculations or measurements) the 
approximate flow rate of the exhaust gas through the enclosure, actual 
cubic feet per minute (acfm).
    8.1.1.2 Calculate the minimum tracer gas injection rate necessary to 
assure a detectable SF6 concentration at the exhaust gas 
measurement point (see section 12.1 for calculation).
    8.1.1.3 Select a flow meter for the injection system with an 
operating range appropriate for the injection rate selected.
    8.1.2 Determination of the Approximate Time to Reach Equilibrium.
    8.1.2.1 Determine the volume of the enclosure.
    8.1.2.2 Calculate the air changes per minute of the enclosure by 
dividing the approximate exhaust flow rate (8.1.1.1 above) by the 
enclosed volume (8.1.2.1 above).
    8.1.2.3 Calculate the time at which the tracer concentration in the 
enclosure will achieve approximate equilibrium. Divide 3 by the air 
changes per minute (8.1.2.2 above) to establish this time. This is the 
approximate length of time for the system to come to equilibrium. 
Concentration equilibrium occurs when the tracer concentration in the 
enclosure stops changing as a function of time for a constant tracer 
release rate. Because the press is continuously cycling, equilibrium may 
be exhibited by a repeating, but stable, cyclic pattern rather than a 
single constant concentration value. Assure sufficient tracer gas is 
available to allow the system to come to equilibrium, and to sample for 
a minimum of 20 minutes and repeat the procedure for a minimum of three 
test runs. Additional test runs may be required based on the results of 
the DQO and LCL analyses described in 40 CFR part 63, subpart KK, 
appendix A.
    8.1.3 Location of Injection Points. This method requires a minimum 
of three tracer gas injection points. The injection points should be 
located within leak prone, volatile organic compound/hazardous air 
pollutant (VOC/HAP) producing areas around the press, or horizontally 
within 12 inches of the defined equipment. One potential configuration 
of the injection points is depicted in Figure 1. The effect of wind, 
exfiltration through the building envelope, and air flowing through open 
building doors should be considered when locating tracer gas injection 
points within the enclosure. The injection points should also be located 
at a vertical elevation equal to the VOC/HAP generating zones. The 
injection points should not be located beneath obstructions that would 
prevent a natural dispersion of the gas. Document the selected injection 
points in a drawing(s).
    8.1.4 Location of Flow Measurement and Tracer Sampling. Accurate CD 
inlet gas flow rate measurements are critical to the success of this 
procedure. Select a measurement location meeting the criteria of EPA 
Method 1 (40 CFR part 60, appendix A), Sampling and Velocity Traverses 
for Stationary Sources. Also, when selecting the measurement location, 
consider whether stratification of the tracer gas is likely at the 
location (e.g., do not select a location immediately after a point of 
air in-leakage to the duct).
    8.2 Tracer Gas Release. Release the tracer gas at a calculated flow 
rate (see section 12.1 for calculation) through a minimum of three 
injection manifolds located as described above in 8.1.3. The tracer gas 
delivery lines must be routed into the enclosure and attached to the 
manifolds without violating the integrity of the enclosure.
    8.3 Pretest Measurements.
    8.3.1 Location of Sampling Point(s). If stratification is not 
suspected at the measurement location, select a single sample point 
located at the centroid of the CD inlet duct or at a point no closer to 
the CD inlet duct walls than 1 meter. If stratification is suspected, 
establish a ``measurement line''

[[Page 278]]

that passes through the centroidal area and in the direction of any 
expected stratification. Locate three traverse points at 16.7, 50.0 and 
83.3 percent of the measurement line and sample from each of these three 
points during each run, or follow the procedure in section 8.3.2 to 
verify whether stratification does or does not exist.
    8.3.2 Stratification Verification. The presence or absence of 
stratification can be verified by using the following procedure. While 
the facility is operating normally, initiate tracer gas release into the 
enclosure. For rectangular ducts, locate at least nine sample points in 
the cross section such that the sample points are the centroids of 
similarly-shaped, equal area divisions of the cross section. Measure the 
tracer gas concentration at each point. Calculate the mean value for all 
sample points. For circular ducts, conduct a 12-point traverse (i.e., 
six points on each of the two perpendicular diameters) locating the 
sample points as described in 40 CFR part 60, appendix A, Method 1. 
Perform the measurements and calculations as described above. Determine 
if the mean pollutant concentration is more than 10 percent different 
from any single point. If so, the cross section is considered to be 
stratified, and the tester may not use a single sample point location, 
but must use the three traverse points at 16.7, 50.0, and 83.3 percent 
of the entire measurement line. Other traverse points may be selected, 
provided that they can be shown to the satisfaction of the Administrator 
to provide a representative sample over the stack or duct cross section.
    8.4 CD Inlet Gas Flow Rate Measurements. The procedures of EPA 
Methods 1-4 (40 CFR part 60, appendix A) are used to determine the CD 
inlet gas flow rate. Molecular weight (Method 3) and moisture (Method 4) 
determinations are only required once for each test series. However, if 
the test series is not completed within 24 hours, then the molecular 
weight and moisture measurements should be repeated daily. As a minimum, 
velocity measurements are conducted according to the procedures of 
Methods 1 and 2 before and after each test run, as close to the start 
and end of the run as practicable. A velocity measurement between two 
runs satisfies both the criterion of ``after'' the run just completed 
and ``before'' the run to be initiated. Accurate exhaust gas flow rate 
measurements are critical to the success of this procedure. If 
significant temporal variations of flow rate are anticipated during the 
test run under normal process operating conditions, take appropriate 
steps to accurately measure the flow rate during the test. Examples of 
steps that might be taken include: (1) conducting additional velocity 
traverses during the test run; or (2) continuously monitoring a single 
point of average velocity during the run and using these data, in 
conjunction with the pre- and post-test traverses, to calculate an 
average velocity for the test run.
    8.5 Tracer Gas Measurement Procedure.
    8.5.1 Calibration Error Test. Immediately prior to the emission test 
(within 2 hours of the start of the test), introduce zero gas and high-
level calibration gas at the calibration valve assembly. Zero and 
calibrate the analyzer according to the manufacturer's procedures using, 
respectively, nitrogen and the calibration gases. Calculate the 
predicted response for the low-level and mid-level gases based on a 
linear response line between the zero and high-level response. Then 
introduce the low-level and mid-level calibration gases successively to 
the measurement system. Record the analyzer responses for the low-level 
and mid-level calibration gases and determine the differences between 
the measurement system responses and the predicted responses using the 
equation in section 12.3. These differences must be less than 5 percent 
of the respective calibration gas value. If not, the measurement system 
must be replaced or repaired prior to testing. No adjustments to the 
measurement system shall be conducted after the calibration and before 
the drift determination (section 8.5.4). If adjustments are necessary 
before the completion of the test series, perform the drift checks prior 
to the required adjustments and repeat the calibration following the 
adjustments. If multiple electronic ranges are to be used, each 
additional range must be checked with a mid-level calibration gas to 
verify the multiplication factor.

    Note: If using an FTIR for the analytical instrument, you may choose 
to follow the pretest preparation, evaluation, and calibration 
procedures of Method 320 (section 8.0) (40 CFR part 63, appendix A) in 
lieu of the above procedure.

    8.5.2 Response Time Test. Conduct this test once prior to each test 
series. Introduce zero gas into the measurement system at the 
calibration valve assembly. When the system output has stabilized, 
switch quickly to the high-level calibration gas. Record the time from 
the concentration change to the measurement system response equivalent 
to 95 percent of the step change. Repeat the test three times and 
average the results.
    8.5.3 SF6 Measurement. Sampling of the enclosure exhaust 
gas at the inlet to the CD should begin at the onset of tracer gas 
release. If necessary, adjust the tracer gas injection rate such that 
the measured tracer gas concentration at the CD inlet is within the 
spectrometer's calibration range (i.e., between the MML and the span 
value). Once the tracer gas concentration reaches equilibrium, the 
SF6 concentration should be measured using the infrared 
spectrometer continuously for at least 20 minutes per run. Continuously 
record (i.e., record at least

[[Page 279]]

once per minute) the concentration. Conduct at least three test runs. On 
the recording chart, in the data acquisition system, or in a log book, 
make a note of periods of process interruption or cyclic operation such 
as the cycles of the hot press operation. Table 1 to this appendix 
summarizes the physical measurements required for the enclosure testing.

    Note: If a GC/ECD is used as the analytical instrument, a continuous 
record (at least once per minute) likely will not be possible; make a 
minimum of five injections during each test run. Also, the minimum test 
run duration criterion of 20 minutes applies.

    8.5.4 Drift Determination. Immediately following the completion of 
the test run, reintroduce the zero and mid-level calibration gases, one 
at a time, to the measurement system at the calibration valve assembly. 
(Make no adjustments to the measurement system until both the zero and 
calibration drift checks are made.) Record the analyzer responses for 
the zero and mid-level calibration gases and determine the difference 
between the instrument responses for each gas prior to and after the 
emission test run using the equation in section 12.4. If the drift 
values exceed the specified limits (section 13), invalidate the test 
results preceding the check and repeat the test following corrections to 
the measurement system. Alternatively, recalibrate the test measurement 
system as in section 8.5.1 and report the results using both sets of 
calibration data (i.e., data determined prior to the test period and 
data determined following the test period). Note: If using an FTIR for 
the analytical instrument, you may choose to follow the post-test 
calibration procedures of Method 320 in appendix A to 40 CFR part 63 
(section 8.11.2) in lieu of the above procedures.
    8.6 Ambient Air Sampling (Optional). Sampling the ambient air 
surrounding the enclosure is optional. However, taking these samples 
during the capture efficiency testing will identify those areas of the 
enclosure that may be performing less efficiently.
    8.6.1 Location of Ambient Samples Outside the Enclosure (Optional). 
In selecting the sampling locations for collecting samples of the 
ambient air surrounding the enclosure, consider potential leak points, 
the direction of the release, and laminar flow characteristics in the 
area surrounding the enclosure. Samples should be collected from all 
sides of the enclosure, downstream in the prevailing room air flow, and 
in the operating personnel occupancy areas.
    8.6.2 Collection of Ambient Samples (Optional). During the tracer 
gas release, collect ambient samples from the area surrounding the 
enclosure perimeter at predetermined location using disposable syringes 
or some other type of containers that are non-absorbent, inert, and that 
have low permeability (i.e., polyvinyl fluoride film or polyester film 
sample bags or polyethylene, polypropylene, nylon or glass bottles). The 
use of disposable syringes allows samples to be injected directly into a 
gas chromatograph. Concentration measurements taken around the perimeter 
of the enclosure provide evidence of capture performance and will assist 
in the identification of those areas of the enclosure that are 
performing less efficiently.
    8.6.3 Analysis and Storage of Ambient Samples (Optional). Analyze 
the ambient samples using an analytical instrument calibrated and 
operated according to the procedures in this appendix or ASTM E 260 and 
ASTM E 697. Samples may be analyzed immediately after a sample is taken, 
or they may be stored for future analysis. Experience has shown no 
degradation of concentration in polypropylene syringes when stored for 
several months as long as the needle or syringe is plugged. 
Polypropylene syringes should be discarded after one use to eliminate 
the possibility of cross contamination of samples.

                           9.0 Quality Control

    9.1 Sampling, System Leak Check. A sampling system leak check should 
be conducted prior to and after each test run to ensure the integrity of 
the sampling system.
    9.2 Zero and Calibration Drift Tests.

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

                  10.0 Calibration and Standardization

    10.1 Control Device Inlet Air Flow Rate Measurement Equipment. 
Follow the equipment calibration requirements specified in Methods 2, 3, 
and 4 (appendix A to 40 CFR part 60) for measuring the velocity, 
molecular weight, and moisture of the control device inlet air.
    10.2 Tracer Gas Injection Rate. A dry gas volume flow meter, mass 
flow meter, or orifice can be used to measure the tracer gas injection 
flow rate. The selected flow measurement device must have an accuracy of 
greater than 5 percent at the field operating 
range. Prior to the test, verify the calibration of the selected flow 
measurement device using either a wet test meter, spirometer, or

[[Page 280]]

liquid displacement meter as the calibration device. Select a minimum of 
two flow rates to bracket the expected field operating range of the flow 
meter. Conduct three calibration runs at each of the two selected flow 
rates. For each run, note the exact quantity of gas as determined by the 
calibration standard and the gas volume indicated by the flow meter. For 
each flow rate, calculate the average percent difference of the 
indicated flow compared to the calibration standard.
    10.3 Spectrometer. Follow the calibration requirements specified by 
the equipment manufacturer for infrared spectrometer measurements and 
conduct the pretest calibration error test specified in section 8.5.1. 
Note: if using an FTIR analytical instrument see Method 320, section 10 
(appendix A to 40 CFR part 63).
    10.4 Gas Chromatograph. Follow the pre-test calibration requirements 
specified in section 8.5.1.
    10.5 Gas Chromatograph for Ambient Sampling (Optional). For the 
optional ambient sampling, follow the calibration requirements specified 
in section 8.5.1 or ASTM E 260 and E 697 and by the equipment 
manufacturer for gas chromatograph measurements.

                       11.0 Analytical Procedures

    The sample collection and analysis are concurrent for this method 
(see section 8.0).

                   12.0 Calculations and Data Analysis

    12.1 Estimate MML and Span. The MML is the minimum measurement 
level. The selection of this level is at the discretion of the tester. 
However, the MML must be higher than the low-level calibration standard, 
and the tester must be able to measure at this level with a precision of 
<=10 percent. As an example, select the MML as 10 times the instrument's 
published detection limit. The detection limit of one instrument is 0.01 
parts per million by volume (ppmv). Therefore, the MML would be 0.10 
ppmv. Select the low-level calibration standard as 0.08 ppmv. The high-
level standard would be four times the low-level standard or 0.32 ppmv. 
A reasonable mid-level standard would then be 0.20 ppmv (halfway between 
the low-level standard and the high-level standard). Finally, the span 
value would be approximately 0.40 ppmv (the high-level value is 80 
percent of the span). In this example, the following MML, calibration 
standards, and span values would apply:
MML = 0.10 ppmv
Low-level standard = 0.08 ppmv
Mid-level standard = 0.20 ppmv
High-level standard = 0.32 ppmv
Span value = 0.40 ppmv
    12.2 Estimate Tracer Gas Injection Rate for the Given Span. To 
estimate the minimum and maximum tracer gas injection rate, assume a 
worst case capture efficiency of 80 percent, and calculate the tracer 
gas flow rate based on known or measured parameters. To estimate the 
minimum tracer gas injection rate, assume that the MML concentration (10 
times the IR detection limit in this example) is desired at the 
measurement location. The following equation can be used to estimate the 
minimum tracer gas injection rate:

((QT-MIN x 0.8)/QE) x (CT / 100) x 
          10\6\ = MML

QT-MIN = 1.25 x MML x (QE/CT) x 
          10-4

Where:

QT-MIN = minimum volumetric flow rate of tracer gas injected, 
          standard cubic feet per minute (scfm);
QE = volumetric flow rate of exhaust gas, scfm;
CT = Tracer gas (SF6) concentration in gas blend, 
          percent by volume;
MML = minimum measured level, ppmv = 10 x IRDL (for this 
          example);
IRDL = IR detection limit, ppmv.

    Standard conditions: 20 [deg]C, 760 millimeters of mercury (mm Hg).
    To estimate the maximum tracer gas injection rate, assume that the 
span value is desired at the measurement location. The following 
equation can be used to estimate the maximum tracer gas injection rate:

((QT-MAX x 0.8)/QE) x (CT / 100) x 
          10\6\ = span value

QT-MAX = 1.25 x span value x (QE/CT) x 
          10-4

Where:

QT-MAX = maximum volumetric flow rate of tracer gas injected, 
          scfm;
Span value = instrument span value, ppmv.

    The following example illustrates this calculation procedure:
    Find the range of volumetric flow rate of tracer gas to be injected 
when the following parameters are known:

QE = 60,000 scfm (typical exhaust gas flow rate from an 
          enclosure);
CT = 2 percent SF6 in nitrogen;
IRDL = 0.01 ppmv (per manufacturer's specifications);
MML = 10 x IRDL = 0.10 ppmv;
Span value = 0.40 ppmv;
QT = ?

Minimum tracer gas volumetric flow rate:

QT-MIN = 1.25 x MML x (QE/CT) x 
          10-4

QT-MIN = 1.25 x 0.10 x (60,000/2) x 10-4 = 0.375 
          scfm

Maximum tracer gas volumetric flow rate:

QT-MAX = 1.25 x span value x (QE/CT) x 
          10-4

    QT-MAX = 1.25 x 0.40 x (60,000/2) x 10-4 = 1.5 
scfm

    In this example, the estimated total volumetric flow rate of the two 
percent SF6 tracer gas injected through the manifolds in the 
enclosure lies between 0.375 and 1.5 scfm.

[[Page 281]]

    12.3 Calibration Error. Calculate the calibration error for the low-
level and mid-level calibration gases using the following equation:

    Err = [verbar]Cstd-Cmeasverbar; / 
Cstd x 100

Where:

Err = calibration error, percent;
Cstd = low-level or mid-level calibration gas value, ppmv;
Cmeas = measured response to low-level or mid-level 
          concentration gas, ppmv.

    12.4 Calibration Drift. Calculate the calibration drift for the zero 
and low-level calibration gases using the following equation:

D = [bond]verbar;Cinitial - Cfinal [bond]verbar; / 
          Cspan x 100

Where:

D = calibration drift, percent;
Cinitial = low-level or mid-level calibration gas value 
          measured before test run, ppmv;
Cfinal = low-level or mid-level calibration gas value 
          measured after test run, ppmv;
Cspan = span value, ppmv.

    12.5 Calculate Capture Efficiency. The equation to calculate 
enclosure capture efficiency is provided below:

CE = (SF6-CD / SF6-INJ) x 100

Where:

CE = capture efficiency;
SF6-CD = mass of SF6 measured at the inlet to the 
          CD;
SF6-INJ = mass of SF6 injected from the tracer 
          source into the enclosure.

Calculate the CE for each of the initial three test runs. Then follow 
the procedures outlined in section 12.6 to calculate the overall capture 
efficiency.
    12.6 Calculate Overall Capture Efficiency. After calculating the 
capture efficiency for each of the initial three test runs, follow the 
procedures in 40 CFR part 63, subpart KK, appendix A, to determine if 
the results of the testing can be used in determining compliance with 
the requirements of the rule. There are two methods that can be used: 
the DQO and LCL methods. The DQO method is described in section 3 of 40 
CFR part 63, subpart KK, appendix A, and provides a measure of the 
precision of the capture efficiency testing conducted. Section 3 of 40 
CFR part 63, subpart KK, appendix A, provides an example calculation 
using results from a facility. If the DQO criteria are met using the 
first set of three test runs, then the facility can use the average 
capture efficiency of these test results to determine the capture 
efficiency of the enclosure. If the DQO criteria are not met, then the 
facility can conduct another set of three runs and run the DQO analysis 
again using the results from the six runs OR the facility can elect to 
use the LCL approach.
    The LCL method is described in section 4 of 40 CFR part 63, subpart 
KK, appendix A, and provides sources that may be performing much better 
than their regulatory requirement, a screening option by which they can 
demonstrate compliance. The LCL approach compares the 80 percent lower 
confidence limit for the mean measured CE value to the applicable 
regulatory requirement. If the LCL capture efficiency is higher than the 
applicable limit, then the facility is in initial compliance and would 
use the LCL capture efficiency as the capture efficiency to determine 
compliance. If the LCL capture efficiency is lower than the applicable 
limit, then the facility must perform additional test runs and re-run 
the DQO or LCL analysis.

                         13.0 Method Performance

    13.1 Measurement System Performance Specifications.
    13.1.1 Zero Drift. Less than 3 percent of the 
span value.
    13.1.2 Calibration Drift. Less than 3 percent 
of the span value.
    13.1.3 Calibration Error. Less than 5 percent 
of the calibration gas value.
    13.2 Flow Measurement Specifications. The mass flow, volumetric 
flow, or critical orifice control meter used should have an accuracy of 
greater than 5 percent at the flow rate used.
    13.3 Calibration and Tracer Gas Specifications. The manufacturer of 
the calibration and tracer gases should provide a recommended shelf life 
for each calibration gas cylinder over which the concentration does not 
change more than 2 percent from the certified 
value.

[69 FR 5063, Feb. 3, 2004, as amended at 71 FR 42904, July 28, 2006]



Sec. 63.2342  When do I have to comply with this subpart?

    (a) If you have a new or reconstructed affected source, you must 
comply with this subpart according to the schedule identified in 
paragraph (a)(1), (a)(2), or (a)(3) of this section, as applicable.
    (1)(i) Except as provided in paragraph (a)(1)(ii) of this section, 
if you startup your new affected source on or before February 3, 2004 or 
if you reconstruct your affected source on or before February 3, 2004, 
you must comply with the emission limitations, operating limits, and 
work practice standards for new and reconstructed sources in this 
subpart no later than February 3, 2004.
    (ii) For any emission source listed in paragraph Sec. 63.2338(b) at 
an affected source that commenced construction or reconstruction after 
April 2, 2002, but before February 3, 2004, that is required to be 
controlled based on the applicability criteria in this subpart, but:
    (A) Would not have been required to be controlled based on the 
applicability criteria as proposed for this subpart, you must comply 
with the emission limitations, operating limits, and work practice 
standards for each such emission source based on the schedule found in 
paragraph (b) of this section or at startup, whichever is later; or
    (B) Would have been subject to a less stringent degree of control 
requirement as proposed for this subpart, you must comply with the 
emission limitations, operating limits, and work practice standards in 
this subpart for each such emission source based on the schedule found 
in paragraph (b) of this section or at startup, whichever is later, and 
if you start up your affected new or reconstructed source before 
February 5, 2007, you must comply with the emission limitations, 
operating limits, and work practice standards for each such emission 
source as proposed

[[Page 286]]

for this subpart, until you are required to comply with the emission 
limitations, operating limits, and work practice standards in this 
subpart for each such emission source based on the schedule found in 
paragraph (b) of this section.
    (2) If you commence construction of or reconstruct your affected 
source after February 3, 2004, you must comply with the emission 
limitations, operating limits, and work practice standards for new and 
reconstructed sources in this subpart upon startup of your affected 
source.
    (3) If, after startup of a new affected source, the total actual 
annual facility-level organic liquid loading volume at that source 
exceeds the criteria for control in Table 2 to this subpart, items 9 and 
10, the owner or operator must comply with the transfer rack 
requirements specified in Sec. 63.2346(b) immediately; that is, be in 
compliance the first day of the period following the end of the 3-year 
period triggering the control criteria.
    (b)(1) If you have an existing affected source, you must comply with 
the emission limitations, operating limits, and work practice standards 
for existing affected sources no later than February 5, 2007, except as 
provided in paragraphs (b)(2) and (3) of this section.
    (2) Floating roof storage tanks at existing affected sources must be 
in compliance with the work practice standards in Table 4 to this 
subpart, item 1, at all times after the next degassing and cleaning 
activity or within 10 years after February 3, 2004, whichever occurs 
first. If the first degassing and cleaning activity occurs during the 3 
years following February 3, 2004, the compliance date is February 5, 
2007.
    (3)(i) If an addition or change other than reconstruction as defined 
in Sec. 63.2 is made to an existing affected facility that causes the 
total actual annual facility-level organic liquid loading volume to 
exceed the criteria for control in Table 2 to this subpart, items 7 and 
8, the owner or operator must comply with the transfer rack requirements 
specified in Sec. 63.2346(b) immediately; that is, be in compliance the 
first day of the period following the end of the 3-year period 
triggering the control criteria.
    (ii) If the owner or operator believes that compliance with the 
transfer rack emission limits cannot be achieved immediately, as 
specified in paragraph (b)(3)(i) of this section, the owner or operator 
may submit a request for a compliance extension, as specified in 
paragraphs (b)(3)(ii)(A) through (I) of this section. Subject to 
paragraph (b)(3)(ii)(B) of this section, until an extension of 
compliance has been granted by the Administrator (or a State with an 
approved permit program) under this paragraph (b)(3)(ii), the owner or 
operator of the transfer rack subject to the requirements of this 
section shall comply with all applicable requirements of this subpart. 
Advice on requesting an extension of compliance may be obtained from the 
Administrator (or the State with an approved permit program).
    (A) Submittal. The owner or operator shall submit a request for a 
compliance extension to the Administrator (or a State, when the State 
has an approved 40 CFR part 70 permit program and the source is required 
to obtain a 40 CFR part 70 permit under that program, or a State, when 
the State has been delegated the authority to implement and enforce the 
emission standard for that source) seeking an extension allowing the 
source up to 1 additional year to comply with the transfer rack 
standard, if such additional period is necessary for the installation of 
controls. The owner or operator of the affected source who has requested 
an extension of compliance under this paragraph (b)(3)(ii)(A) and who is 
otherwise required to obtain a title V permit shall apply for such 
permit, or apply to have the source's title V permit revised to 
incorporate the conditions of the extension of compliance. The 
conditions of an extension of compliance granted under this paragraph 
(b)(3)(ii)(A) will be incorporated into the affected source's title V 
permit according to the provisions of 40 CFR part 70 or Federal title V 
regulations in this chapter (42 U.S.C. 7661), whichever are applicable.
    (B) When to submit. (1) Any request submitted under paragraph 
(b)(3)(ii)(A) of this section must be submitted in writing to the 
appropriate authority no later than 120 days prior to the affected 
source's compliance date (as specified

[[Page 287]]

in paragraph (b)(3)(i) of this section), except as provided for in 
paragraph (b)(3)(ii)(B)(2) of this section. Nonfrivolous requests 
submitted under this paragraph (b)(3)(ii)(B)(1) will stay the 
applicability of the rule as to the emission points in question until 
such time as the request is granted or denied. A denial will be 
effective as of the date of denial.
    (2) An owner or operator may submit a compliance extension request 
after the date specified in paragraph (b)(3)(ii)(B)(1) of this section 
provided the need for the compliance extension arose after that date, 
and before the otherwise applicable compliance date and the need arose 
due to circumstances beyond reasonable control of the owner or operator. 
This request must include, in addition to the information required in 
paragraph (b)(3)(ii)(C) of this section, a statement of the reasons 
additional time is needed and the date when the owner or operator first 
learned of the problems. Nonfrivolous requests submitted under this 
paragraph (b)(3)(ii)(B)(2) will stay the applicability of the rule as to 
the emission points in question until such time as the request is 
granted or denied. A denial will be effective as of the original 
compliance date.
    (C) Information required. The request for a compliance extension 
under paragraph (b)(3)(ii)(A) of this section shall include the 
following information:
    (1) The name and address of the owner or operator and the address of 
the existing source if it differs from the address of the owner or 
operator;
    (2) The name, address, and telephone number of a contact person for 
further information;
    (3) An identification of the organic liquid distribution operation 
and of the specific equipment for which additional compliance time is 
required;
    (4) A description of the controls to be installed to comply with the 
standard;
    (5) Justification for the length of time being requested; and
    (6) A compliance schedule, including the date by which each step 
toward compliance will be reached. At a minimum, the list of dates shall 
include:
    (i) The date by which on-site construction, installation of emission 
control equipment, or a process change is planned to be initiated;
    (ii) The date by which on-site construction, installation of 
emission control equipment, or a process change is to be completed; and
    (iii) The date by which final compliance is to be achieved.
    (D) Approval of request for extension of compliance. Based on the 
information provided in any request made under paragraph (b)(3)(ii)(C) 
of this section, or other information, the Administrator (or the State 
with an approved permit program) may grant an extension of compliance 
with the transfer rack emission standard, as specified in paragraph 
(b)(3)(ii) of this section. The extension will be in writing and will--
    (1) Identify each affected source covered by the extension;
    (2) Specify the termination date of the extension;
    (3) Specify the dates by which steps toward compliance are to be 
taken, if appropriate;
    (4) Specify other applicable requirements to which the compliance 
extension applies (e.g., performance tests);
    (5) Specify the contents of the progress reports to be submitted and 
the dates by which such reports are to be submitted, if required 
pursuant to paragraph (b)(3)(ii)(E) of this section.
    (6) Under paragraph (b)(3)(ii) of this section, specify any 
additional conditions that the Administrator (or the State) deems 
necessary to assure installation of the necessary controls and 
protection of the health of persons during the extension period.
    (E) Progress reports. The owner or operator of an existing source 
that has been granted an extension of compliance under paragraph 
(b)(3)(ii)(D) of this section may be required to submit to the 
Administrator (or the State with an approved permit program) progress 
reports indicating whether the steps toward compliance outlined in the 
compliance schedule have been reached.
    (F) Notification of approval or intention to deny. (1) The 
Administrator (or the State with an approved permit program) will notify 
the owner or operator in writing of approval or intention to

[[Page 288]]

deny approval of a request for an extension of compliance within 30 
calendar days after receipt of sufficient information to evaluate a 
request submitted under paragraph (b)(3)(ii) of this section. The 
Administrator (or the State) will notify the owner or operator in 
writing of the status of his/her application; that is, whether the 
application contains sufficient information to make a determination, 
within 30 calendar days after receipt of the original application and 
within 30 calendar days after receipt of any supplementary information 
that is submitted. The 30-day approval or denial period will begin after 
the owner or operator has been notified in writing that his/her 
application is complete. Failure by the Administrator to act within 30 
calendar days to approve or disapprove a request submitted under 
paragraph (b)(3)(ii) of this section does not constitute automatic 
approval of the request.
    (2) When notifying the owner or operator that his/her application is 
not complete, the Administrator will specify the information needed to 
complete the application and provide notice of opportunity for the 
applicant to present, in writing, within 30 calendar days after he/she 
is notified of the incomplete application, additional information or 
arguments to the Administrator to enable further action on the 
application.
    (3) Before denying any request for an extension of compliance, the 
Administrator (or the State with an approved permit program) will notify 
the owner or operator in writing of the Administrator's (or the State's) 
intention to issue the denial, together with:
    (i) Notice of the information and findings on which the intended 
denial is based; and
    (ii) Notice of opportunity for the owner or operator to present in 
writing, within 15 calendar days after he/she is notified of the 
intended denial, additional information or arguments to the 
Administrator (or the State) before further action on the request.
    (4) The Administrator's final determination to deny any request for 
an extension will be in writing and will set forth the specific grounds 
on which the denial is based. The final determination will be made 
within 30 calendar days after presentation of additional information or 
argument (if the application is complete), or within 30 calendar days 
after the final date specified for the presentation if no presentation 
is made.
    (G) Termination of extension of compliance. The Administrator (or 
the State with an approved permit program) may terminate an extension of 
compliance at an earlier date than specified if any specification under 
paragraph (b)(3)(ii)(D)(3) or paragraph (b)(3)(ii)(D)(4) of this section 
is not met. Upon a determination to terminate, the Administrator will 
notify, in writing, the owner or operator of the Administrator's 
determination to terminate, together with:
    (1) Notice of the reason for termination; and
    (2) Notice of opportunity for the owner or operator to present in 
writing, within 15 calendar days after he/she is notified of the 
determination to terminate, additional information or arguments to the 
Administrator before further action on the termination.
    (3) A final determination to terminate an extension of compliance 
will be in writing and will set forth the specific grounds on which the 
termination is based. The final determination will be made within 30 
calendar days after presentation of additional information or arguments, 
or within 30 calendar days after the final date specified for the 
presentation if no presentation is made.
    (H) The granting of an extension under this section shall not 
abrogate the Administrator's authority under section 114 of the CAA.
    (I) Limitation on use of compliance extension. The owner or operator 
may request an extension of compliance under the provisions specified in 
paragraph (b)(3)(ii) of this section only once for each facility.
    (c) If you have an area source that does not commence reconstruction 
but increases its emissions or its potential to emit such that it 
becomes a major source of HAP emissions and an existing affected source 
subject to this subpart, you must be in compliance by 3 years after the 
area source becomes a major source.

[[Page 289]]

    (d) You must meet the notification requirements in Sec. Sec. 
63.2343 and 63.2382(a), as applicable, according to the schedules in 
Sec. 63.2382(a) and (b)(1) through (3) and in subpart A of this part. 
Some of these notifications must be submitted before the compliance 
dates for the emission limitations, operating limits, and work practice 
standards in this subpart.

   Emission Limitations, Operating Limits, and Work Practice Standards



Sec. 63.2346  What emission limitations, operating limits, and work
practice standards must I meet?

    (a) Storage tanks. For each storage tank storing organic liquids 
that meets the tank capacity and liquid vapor pressure criteria for 
control in Table 2 to this subpart, items 1 through 5, you must comply 
with paragraph (a)(1), (a)(2), (a)(3), or (a)(4) of this section. For 
each storage tank storing organic liquids that meets the tank capacity 
and liquid vapor pressure criteria for control in Table 2 to this 
subpart, item 6, you must comply with paragraph (a)(1), (a)(2), or 
(a)(4) of this section.
    (1) Meet the emission limits specified in Table 2 to this subpart 
and comply with the applicable requirements specified in 40 CFR part 63, 
subpart SS, for meeting emission limits, except substitute the term 
``storage tank'' at each occurrence of the term ``storage vessel'' in 
subpart SS.
    (2) Route emissions to fuel gas systems or back into a process as 
specified in 40 CFR part 63, subpart SS.
    (3) Comply with 40 CFR part 63, subpart WW (control level 2).
    (4) Use a vapor balancing system that complies with the requirements 
specified in paragraphs (a)(4)(i) through (vii) of this section and with 
the recordkeeping requirements specified in Sec. 63.2390(e).
    (i) The vapor balancing system must be designed and operated to 
route organic HAP vapors displaced from loading of the storage tank to 
the transport vehicle from which the storage tank is filled.
    (ii) Transport vehicles must have a current certification in 
accordance with the United States Department of Transportation (U.S. 
DOT) pressure test requirements of 49 CFR part 180 for cargo tanks and 
49 CFR 173.31 for tank cars.
    (iii) Organic liquids must only be unloaded from cargo tanks or tank 
cars when vapor collection systems are connected to the storage tank's 
vapor collection system.
    (iv) No pressure relief device on the storage tank, or on the cargo 
tank or tank car, shall open during loading or as a result of diurnal 
temperature changes (breathing losses).
    (v) Pressure relief devices must be set to no less than 2.5 pounds 
per square inch guage (psig) at all times to prevent breathing losses. 
Pressure relief devices may be set at values less than 2.5 psig if the 
owner or operator provides rationale in the notification of compliance 
status report explaining why the alternative value is sufficient to 
prevent breathing losses at all times. The owner or operator shall 
comply with paragraphs (a)(4)(v)(A) through (C) of this section for each 
pressure relief valve.
    (A) The pressure relief valve shall be monitored quarterly using the 
method described in Sec. 63.180(b).
    (B) An instrument reading of 500 parts per million by volume (ppmv) 
or greater defines a leak.
    (C) When a leak is detected, it shall be repaired as soon as 
practicable, but no later than 5 days after it is detected, and the 
owner or operator shall comply with the recordkeeping requirements of 
Sec. 63.181(d)(1) through (4).
    (vi) Cargo tanks and tank cars that deliver organic liquids to a 
storage tank must be reloaded or cleaned at a facility that utilizes the 
control techniques specified in paragraph (a)(4)(vi)(A) or (a)(4)(vi)(B) 
of this section.
    (A) The cargo tank or tank car must be connected to a closed-vent 
system with a control device that reduces inlet emissions of total 
organic HAP by 95 percent by weight or greater or to an exhaust 
concentration less than or equal to 20 ppmv, on a dry basis corrected to 
3 percent oxygen for combustion devices using supplemental combustion 
air.

[[Page 292]]

    (B) A vapor balancing system designed and operated to collect 
organic HAP vapor displaced from the cargo tank or tank car during 
reloading must be used to route the collected vapor to the storage tank 
from which the liquid being transferred originated or to another storage 
tank connected to a common header.
    (vii) The owner or operator of the facility where the cargo tank or 
tank car is reloaded or cleaned must comply with paragraphs 
(a)(4)(vii)(A) through (D) of this section.
    (A) Submit to the owner or operator of the storage tank and to the 
Administrator a written certification that the reloading or cleaning 
facility will meet the requirements of paragraph (a)(4)(vii)(A) through 
(C) of this section. The certifying entity may revoke the written 
certification by sending a written statement to the owner or operator of 
the storage tank giving at least 90 days notice that the certifying 
entity is rescinding acceptance of responsibility for compliance with 
the requirements of this paragraph (a)(4)(vii) of this section.
    (B) If complying with paragraph (a)(4)(vi)(A) of this section, 
comply with the requirements for a closed vent system and control device 
as specified in this subpart EEEE. The notification requirements in 
Sec. 63.2382 and the reporting requirements in Sec. 63.2386 do not 
apply to the owner or operator of the offsite cleaning or reloading 
facility.
    (C) If complying with paragraph (a)(4)(vi)(B) of this section, keep 
the records specified in Sec. 63.2390(e)(3) or equivalent recordkeeping 
approved by the Administrator.
    (D) After the compliance dates specified in Sec. 63.2342, at an 
offsite reloading or cleaning facility subject to Sec. 63.2346(a)(4), 
compliance with the monitoring, recordkeeping, and reporting provisions 
of any other subpart of this part 63 that has monitoring, recordkeeping, 
and reporting provisions constitutes compliance with the monitoring, 
recordkeeping and reporting provisions of Sec. 63.2346(a)(4)(vii)(B) or 
Sec. 63.2346(a)(4)(vii)(C). You must identify in your notification of 
compliance status report required by Sec. 63.2382(d) the subpart of 
this part 63 with which the owner or operator of the offsite reloading 
or cleaning facility complies.
    (b) Transfer racks. For each transfer rack that is part of the 
collection of transfer racks that meets the total actual annual 
facility-level organic liquid loading volume criterion for control in 
Table 2 to this subpart, items 7 through 10, you must comply with 
paragraph (b)(1), (b)(2), or (b)(3) of this section for each arm in the 
transfer rack loading an organic liquid whose organic HAP content meets 
the organic HAP criterion for control in Table 2 to this subpart, items 
7 through 10. For existing affected sources, you must comply with 
paragraph (b)(1), (b)(2), or (b)(3)(i) of this section during the 
loading of organic liquids into transport vehicles. For new affected 
sources, you must comply with paragraph (b)(1), (b)(2), or (b)(3)(i) and 
(ii) of this section during the loading of organic liquids into 
transport vehicles and containers. If the total actual annual facility-
level organic liquid loading volume at any affected source is equal to 
or greater than the loading volume criteria for control in Table 2 to 
this subpart, but at a later date is less than the loading volume 
criteria for control, compliance with paragraph (b)(1), (b)(2), or 
(b)(3) of this section is no longer required. For new sources and 
reconstructed sources, as defined in Sec. 63.2338(d) and (e), if at a 
later date, the total actual annual facility-level organic liquid 
loading volume again becomes equal to or greater than the loading volume 
criteria for control in Table 2 to this subpart, the owner or operator 
must comply with paragraph (b)(1), (b)(2), or (b)(3)(i) and (ii) of this 
section immediately, as specified in Sec. 63.2342(a)(3). For existing 
sources, as defined in Sec. 63.2338(f), if at a later date, the total 
actual annual facility-level organic liquid loading volume again becomes 
equal to or greater than the loading volume criteria for control in 
Table 2 to this subpart, the owner or operator must comply with 
paragraph (b)(1), (b)(2), or (b)(3)(i) of this section immediately, as 
specified in Sec. 63.2342(b)(3)(i), unless an alternative compliance 
schedule has been approved under Sec. 63.2342(b)(3)(ii) and subject to 
the use limitation specified in Sec. 63.2342(b)(3)(ii)(I).

[[Page 293]]

    (1) Meet the emission limits specified in Table 2 to this subpart 
and comply with the applicable requirements for transfer racks specified 
in 40 CFR part 63, subpart SS, for meeting emission limits.
    (2) Route emissions to fuel gas systems or back into a process as 
specified in 40 CFR part 63, subpart SS.
    (3)(i) Use a vapor balancing system that routes organic HAP vapors 
displaced from the loading of organic liquids into transport vehicles to 
the storage tank from which the liquid being loaded originated or to 
another storage tank connected to a common header.
    (ii) Use a vapor balancing system that routes the organic HAP vapors 
displaced from the loading of organic liquids into containers directly 
(e.g., no intervening tank or containment area such as a room) to the 
storage tank from which the liquid being loaded originated or to another 
storage tank connected to a common header.
    (c) Equipment leak components. For each pump, valve, and sampling 
connection that operates in organic liquids service for at least 300 
hours per year, you must comply with the applicable requirements under 
40 CFR part 63, subpart TT (control level 1), subpart UU (control level 
2), or subpart H. Pumps, valves, and sampling connectors that are 
insulated to provide protection against persistent sub-freezing 
temperatures are subject to the ``difficult to monitor'' provisions in 
the applicable subpart selected by the owner or operator. This paragraph 
only applies if the affected source has at least one storage tank or 
transfer rack that meets the applicability criteria for control in Table 
2 to this subpart.
    (d) Transport vehicles. For each transport vehicle equipped with 
vapor collection equipment that is loaded at a transfer rack that is 
subject to control based on the criteria specified in Table 2 to this 
subpart, items 7 through 10, you must comply with paragraph (d)(1) of 
this section. For each transport vehicle without vapor collection 
equipment that is loaded at a transfer rack that is subject to control 
based on the criteria specified in Table 2 to this subpart, items 7 
through 10, you must comply with paragraph (d)(2) of this section.
    (1) Follow the steps in 40 CFR 60.502(e) to ensure that organic 
liquids are loaded only into vapor-tight transport vehicles and comply 
with the provisions in 40 CFR 60.502(f) through (i), except substitute 
the term ``transport vehicle'' at each occurrence of the term ``tank 
truck'' or ``gasoline tank truck'' in those paragraphs.
    (2) Ensure that organic liquids are loaded only into transport 
vehicles that have a current certification in accordance with the U.S. 
Department of Transportation (DOT) pressure test requirements in 49 CFR 
part 180 for cargo tanks or 49 CFR 173.31 for tank cars.
    (e) Operating limits. For each high throughput transfer rack, you 
must meet each operating limit in Table 3 to this subpart for each 
control device used to comply with the provisions of this subpart 
whenever emissions from the loading of organic liquids are routed to the 
control device. For each storage tank and low throughput transfer rack, 
you must comply with the requirements for monitored parameters as 
specified in subpart SS of this part for storage vessels and, during the 
loading of organic liquids, for low throughput transfer racks, 
respectively. Alternatively, you may comply with the operating limits in 
Table 3 to this subpart.
    (f) For noncombustion devices, if you elect to demonstrate 
compliance with a percent reduction requirement in Table 2 to this 
subpart using total organic compounds (TOC) rather than organic HAP, you 
must first demonstrate, subject to the approval of the Administrator, 
that TOC is an appropriate surrogate for organic HAP in your case; that 
is, for your storage tank(s) and/or transfer rack(s), the percent 
destruction of organic HAP is equal to or higher than the percent 
destruction of TOC. This demonstration must be conducted prior to or 
during the initial compliance test.
    (g) As provided in Sec. 63.6(g), you may request approval from the 
Administrator to use an alternative to the emission limitations, 
operating limits, and work practice standards in this section. You must 
follow the procedures in Sec. 63.177(b) through (e) in applying for 
permission to use such an alternative. If you apply for permission to

[[Page 294]]

use an alternative to the emission limitations, operating limits, and 
work practice standards in this section, you must submit the information 
described in Sec. 63.6(g)(2).
    (h) [Reserved]
    (i) Opening of a safety device is allowed at any time that it is 
required to avoid unsafe operating conditions.
    (j) If you elect to comply with this subpart by combining emissions 
from different emission sources subject to this subpart in a single 
control device, then you must comply with the provisions specified in 
Sec. 63.982(f).

[69 FR 5063, Feb. 3, 2004, as amended at 71 FR 42909, July 28, 2006]

               Testing and Initial Compliance Requirements



Sec. 63.2354  What performance tests, design evaluations, and
performance evaluations must I conduct?

    (a)(1) For each performance test that you conduct, you must use the 
procedures specified in subpart SS of this part and the provisions 
specified in paragraph (b) of this section.
    (2) For each design evaluation you conduct, you must use the 
procedures specified in subpart SS of this part.
    (3) For each performance evaluation of a continuous emission 
monitoring system (CEMS) you conduct, you must follow the requirements 
in Sec. 63.8(e).
    (b)(1) For nonflare control devices, you must conduct each 
performance test according to the requirements in Sec. 63.7(e)(1), and 
either Sec. 63.988(b), Sec. 63.990(b), or Sec. 63.995(b), using the 
procedures specified in Sec. 63.997(e).
    (2) You must conduct three separate test runs for each performance 
test on a nonflare control device as specified in Sec. Sec. 63.7(e)(3) 
and 63.997(e)(1)(v). Each test run must last at least 1 hour, except as 
provided in Sec. 63.997(e)(1)(v)(A) and (B).
    (3)(i) In addition to EPA Method 25 or 25A of 40 CFR part 60, 
appendix A, to determine compliance with the organic HAP or TOC emission 
limit, you may use EPA Method 18 of 40 CFR part 60, appendix A, as 
specified in paragraph (b)(3)(i) of this section. As an alternative to 
EPA Method 18, you may use ASTM D6420-99 (Reapproved 2004), Standard 
Test Method for Determination of Gaseous Organic Compounds by Direct 
Interface Gas Chromatography-Mass Spectrometry (incorporated by 
reference, see Sec. 63.14), under the conditions specified in paragraph 
(b)(3)(ii) of this section.
    (A) If you use EPA Method 18 to measure compliance with the 
percentage efficiency limit, you must first determine which organic HAP 
are present in the inlet gas stream (i.e., uncontrolled emissions) using 
knowledge of the organic liquids or the screening procedure described in 
EPA Method 18. In conducting the performance test, you must analyze 
samples collected as specified in EPA Method 18, simultaneously at the 
inlet and outlet of the control device. Quantify the emissions for the 
same organic HAP identified as present in the inlet gas stream for both 
the inlet and outlet gas streams of the control device.
    (B) If you use EPA Method 18 of 40 CFR part 60, appendix A, to 
measure compliance with the emission concentration limit, you must first 
determine which organic HAP are present in the inlet gas stream using 
knowledge of the organic liquids or the screening procedure described in 
EPA Method 18. In conducting the performance test, analyze samples 
collected as specified

[[Page 295]]

in EPA Method 18 at the outlet of the control device. Quantify the 
control device outlet emission concentration for the same organic HAP 
identified as present in the inlet or uncontrolled gas stream.
    (ii) You may use ASTM D6420-99 (Reapproved 2004), Standard Test 
Method for Determination of Gaseous Organic Compounds by Direct 
Interface Gas Chromatography-Mass Spectrometry (incorporated by 
reference, see Sec. 63.14), as an alternative to EPA Method 18 if the 
target concentration is between 150 parts per billion by volume and 100 
ppmv and either of the conditions specified in paragraph (b)(2)(ii)(A) 
or (B) of this section exists. For target compounds not listed in 
Section 1.1 of ASTM D6420-99 (Reapproved 2004) and not amenable to 
detection by mass spectrometry, you may not use ASTM D6420-99 
(Reapproved 2004).
    (A) The target compounds are those listed in Section 1.1 of ASTM 
D6420-99 (Reapproved 2004), Standard Test Method for Determination of 
Gaseous Organic Compounds by Direct Interface Gas Chromatography-Mass 
Spectrometry (incorporated by reference, see Sec. 63.14),; or
    (B) For target compounds not listed in Section 1.1 of ASTM D6420-99 
(Reapproved 2004), Standard Test Method for Determination of Gaseous 
Organic Compounds by Direct Interface Gas Chromatography-Mass 
Spectrometry (incorporated by reference, see Sec. 63.14), but 
potentially detected by mass spectrometry, the additional system 
continuing calibration check after each run, as detailed in ASTM D6420-
99 (Reapproved 2004), Section 10.5.3, must be followed, met, documented, 
and submitted with the data report, even if there is no moisture 
condenser used or the compound is not considered water-soluble.
    (4) If a principal component of the uncontrolled or inlet gas stream 
to the control device is formaldehyde, you may use EPA Method 316 of 
appendix A of this part instead of EPA Method 18 of 40 CFR part 60, 
appendix A, for measuring the formaldehyde. If formaldehyde is the 
predominant organic HAP in the inlet gas stream, you may use EPA Method 
316 alone to measure formaldehyde either at the inlet and outlet of the 
control device using the formaldehyde control efficiency as a surrogate 
for total organic HAP or TOC efficiency, or at the outlet of a 
combustion device for determining compliance with the emission 
concentration limit.
    (5) You may not conduct performance tests during periods of SSM, as 
specified in Sec. 63.7(e)(1).
    (c) To determine the HAP content of the organic liquid, you may use 
EPA Method 311 of 40 CFR part 63, appendix A, or other method approved 
by the Administrator. In addition, you may use other means, such as 
voluntary consensus standards, material safety data sheets (MSDS), or 
certified product data sheets, to determine the HAP content of the 
organic liquid. If the method you select to determine the HAP content 
provides HAP content ranges, you must use the upper end of each HAP 
content range in determining the total HAP content of the organic 
liquid. The EPA may require you to test the HAP content of an organic 
liquid using EPA Method 311 or other method approved by the 
Administrator. If the results of the EPA Method 311 (or any other 
approved method) are different from the HAP content determined by 
another means, the EPA Method 311 (or approved method) results will 
govern.

[69 FR 5063, Feb. 3, 2004, as amended at 71 FR 42910, July 28, 2006]

                   Continuous Compliance Requirements



Sec. 63.2374  When do I monitor and collect data to demonstrate
continuous compliance and how do I use the collected data?

    (a) You must monitor and collect data according to subpart SS of 
this part and paragraphs (b) and (c) of this section.
    (b) When using a control device to comply with this subpart, you 
must monitor continuously or collect data at all required intervals at 
all times that the emission source and control device are in OLD 
operation, except for CMS malfunctions (including any malfunction 
preventing the CMS from operating properly), associated repairs, and 
required quality assurance or control activities (including, as 
applicable, calibration checks and required zero and span adjustments).
    (c) Do not use data recorded during CMS malfunctions, associated 
repairs, required quality assurance or control activities, or periods 
when emissions from organic liquids are not routed to the control device 
in data averages and calculations used to report emission or operating 
levels. Do not use such data in fulfilling a minimum data availability 
requirement, if applicable. You must use all of the data collected 
during all other periods, including periods of SSM, in assessing the 
operation of the control device.



Sec. 63.2378  How do I demonstrate continuous compliance with the 
emission limitations, operating limits, and work practice standards?

    (a) You must demonstrate continuous compliance with each emission 
limitation, operating limit, and work practice standard in Tables 2 
through 4 to this subpart that applies to you according to the methods 
specified in subpart SS of this part and in tables 8 through 10 to this 
subpart, as applicable.
    (b) You must follow the requirements in Sec. 63.6(e)(1) and (3) 
during periods of startup, shutdown, malfunction, or nonoperation of the 
affected source or any part thereof. In addition, the provisions of 
paragraphs (b)(1) through (3) of this section apply.
    (1) The emission limitations in this subpart apply at all times 
except during periods of nonoperation of the affected source (or 
specific portion thereof) resulting in cessation of the emissions to 
which this subpart applies. The emission limitations of this subpart 
apply during periods of SSM, except as provided in paragraphs (b)(2) and 
(3) of this section. However, if a SSM, or period of nonoperation of one 
portion of the affected source does not affect the ability of a 
particular emission source to comply with the emission limitations to 
which it is subject, then that emission source is still required to 
comply with the applicable emission limitations of this subpart during 
the startup, shutdown, malfunction, or period of nonoperation.
    (2) The owner or operator must not shut down control devices or 
monitoring systems that are required or utilized for achieving 
compliance with this subpart during periods of SSM while emissions are 
being routed to such items of equipment if the shutdown would contravene 
requirements of this subpart applicable to such items of equipment. This 
paragraph (b)(2) does not apply if the item of equipment is 
malfunctioning. This paragraph (b)(2) also does not apply if the owner 
or operator shuts down the compliance

[[Page 298]]

equipment (other than monitoring systems) to avoid damage due to a 
contemporaneous SSM of the affected source or portion thereof. If the 
owner or operator has reason to believe that monitoring equipment would 
be damaged due to a contemporaneous SSM of the affected source of 
portion thereof, the owner or operator must provide documentation 
supporting such a claim in the next Compliance report required in table 
11 to this subpart, item 1. Once approved by the Administrator, the 
provision for ceasing to collect, during a SSM, monitoring data that 
would otherwise be required by the provisions of this subpart must be 
incorporated into the SSM plan.
    (3) During SSM, you must implement, to the extent reasonably 
available, measures to prevent or minimize excess emissions. For 
purposes of this paragraph (b)(3), the term ``excess emissions'' means 
emissions greater than those allowed by the emission limits that apply 
during normal operational periods. The measures to be taken must be 
identified in the SSM plan, and may include, but are not limited to, air 
pollution control technologies, recovery technologies, work practices, 
pollution prevention, monitoring, and/or changes in the manner of 
operation of the affected source. Back-up control devices are not 
required, but may be used if available.
    (c) Periods of planned routine maintenance of a control device used 
to control storage tanks or transfer racks, during which the control 
device does not meet the emission limits in table 2 to this subpart, 
must not exceed 240 hours per year.
    (d) If you elect to route emissions from storage tanks or transfer 
racks to a fuel gas system or to a process, as allowed by Sec. 
63.982(d), to comply with the emission limits in table 2 to this 
subpart, the total aggregate amount of time during which the emissions 
bypass the fuel gas system or process during the calendar year without 
being routed to a control device, for all reasons (except SSM or product 
changeovers of flexible operation units and periods when a storage tank 
has been emptied and degassed), must not exceed 240 hours.

for transport within or out of the facility through transfer racks that 
are part of the affected source into transport vehicles (for existing 
affected sources) or into transport vehicles and containers (for new 
affected sources) based on a 3-year rolling average, calculated 
annually.
    (1) For existing affected sources, each 3-year rolling average is 
based on actual facility-level loading volume during each calendar year 
(January 1 through December 31) in the 3-year period. For calendar year 
2004 only (the first year of the initial 3-year rolling average), if an 
owner or operator of an affected source does not have actual loading 
volume data for the time period from January 1, 2004, through February 
2, 2004 (the time period prior to the effective date of the OLD NESHAP), 
the owner or operator shall compute a facility-level loading volume for 
this time period as follows: At the end of the 2004 calendar year, the 
owner or operator shall calculate a daily average facility-level loading 
volume (based on the actual loading volume for February 3, 2004, through 
December 31, 2004) and use that daily average to estimate the facility-
level loading volume for the period of time from January 1, 2004, 
through February 2, 2004. The owner or operator shall then sum the 
estimated facility-level loading volume from January 1, 2004, through 
February 2, 2004, and the actual facility-level loading volume from 
February 3, 2004, through December 31, 2004, to calculate the annual 
facility-level loading volume for calendar year 2004.
    (2)(i) For new affected sources, the 3-year rolling average is 
calculated as an average of three 12-month periods. An owner or operator 
must select as the beginning calculation date with which to start the 
calculations as either the initial startup date of the new affected 
source or the first day of the calendar month following the month in 
which startup occurs. Once selected, the date with which the 
calculations begin cannot be changed.
    (ii) The initial 3-year rolling average is based on the projected 
maximum facility-level annual loading volume for each of the 3 years 
following the selected beginning calculation date. The second 3-year 
rolling average is based on actual facility-level loading volume for the 
first year of operation plus a new projected maximum facility-level 
annual loading volume for second and third years following the selected 
beginning calculation date. The third 3-year rolling average is based on 
actual facility-level loading volume for the first 2 years of operation 
plus a new projected maximum annual facility-level loading volume for 
the third year following the beginning calculation date. Subsequent 3-
year rolling averages are based on actual facility-level loading volume 
for each year in the 3-year rolling average.

    Transfer rack means a single system used to load organic liquids 
into, or unload organic liquids out of, transport vehicles or 
containers. It includes all loading and unloading arms, pumps, meters, 
shutoff valves, relief valves, and other piping and equipment necessary 
for the transfer operation. Transfer equipment and operations that are 
physically separate (i.e., do not share common piping, valves, and other 
equipment) are considered to be separate transfer racks.
    Transport vehicle means a cargo tank or tank car.
    Vapor balancing system means:
    (1) A piping system that collects organic HAP vapors displaced from 
transport vehicles or containers during loading and routes the collected 
vapors to the storage tank from which the liquid being loaded originated 
or to another storage tank connected to a common header. For containers, 
the piping system must route the displaced vapors directly to the 
appropriate storage tank or to another storage tank connected to a 
common header in order to qualify as a vapor balancing system; or
    (2) A piping system that collects organic HAP vapors displaced from 
the loading of a storage tank and routes the collected vapors to the 
transport vehicle from which the storage tank is filled.
    Vapor collection system means any equipment located at the source 
(i.e., at the OLD operation) that is not open to the atmosphere; that is 
composed of piping, connections, and, if necessary, flow-inducing 
devices; and that is used for:
    (1) Containing and conveying vapors displaced during the loading of 
transport vehicles to a control device;
    (2) Containing and directly conveying vapors displaced during the 
loading of containers; or
    (3) Vapor balancing. This does not include any of the vapor 
collection equipment that is installed on the transport vehicle.
    Vapor-tight transport vehicle means a transport vehicle that has 
been demonstrated to be vapor-tight. To be considered vapor-tight, a 
transport vehicle equipped with vapor collection equipment must undergo 
a pressure change of no more than 250 pascals (1 inch of water) within 5 
minutes after it is pressurized to 4,500 pascals (18 inches of water). 
This capability must be demonstrated annually using the procedures 
specified in EPA Method 27 of 40 CFR part 60, appendix A. For all other 
transport vehicles, vapor tightness is demonstrated by performing the 
U.S. DOT pressure test procedures for tank cars and cargo tanks.
    Work practice standard means any design, equipment, work practice, 
or operational standard, or combination thereof, that is promulgated 
pursuant to section 112(h) of the CAA.

 Subpart FFFF_National Emission Standards for Hazardous Air Pollutants: 
              Miscellaneous Organic Chemical Manufacturing

    Source: 68 FR 63888, Nov. 10, 2003, unless otherwise noted.

                        What This Subpart Covers



Sec. 63.2430  What is the purpose of this subpart?

    This subpart establishes national emission standards for hazardous 
air pollutants (NESHAP) for miscellaneous organic chemical 
manufacturing. This subpart also establishes requirements to demonstrate 
initial and continuous compliance with the emission limits, operating 
limits, and work practice standards.



Sec. 63.2435  Am I subject to the requirements in this subpart?

    (a) You are subject to the requirements in this subpart if you own 
or operate miscellaneous organic chemical manufacturing process units 
(MCPU) that are located at, or are part of, a major source of hazardous 
air pollutants (HAP) emissions as defined in section 112(a) of the Clean 
Air Act (CAA).
    (b) An MCPU includes equipment necessary to operate a miscellaneous 
organic chemical manufacturing process, as defined in Sec. 63.2550, 
that satisfies all of the conditions specified in paragraphs (b)(1) 
through (3) of this section. An MCPU also includes any assigned storage 
tanks and transfer racks; equipment in open systems that is used to 
convey or store water having the same concentration and flow 
characteristics as wastewater; and components such as pumps, 
compressors, agitators, pressure relief devices, sampling connection 
systems, open-ended

[[Page 327]]

valves or lines, valves, connectors, and instrumentation systems that 
are used to manufacture any material or family of materials described in 
paragraphs (b)(1)(i) through (v) of this section.
    (1) The MCPU produces material or family of materials that is 
described in paragraph (b)(1)(i), (ii), (iii), (iv), or (v) of this 
section.
    (i) An organic chemical(s) classified using the 1987 version of SIC 
code 282, 283, 284, 285, 286, 287, 289, or 386, except as provided in 
paragraph (c)(5) of this section.
    (ii) An organic chemical(s) classified using the 1997 version of 
NAICS code 325, except as provided in paragraph (c)(5) of this section.
    (iii) Quaternary ammonium compounds and ammonium sulfate produced 
with caprolactam.
    (iv) Hydrazine.
    (v) Organic solvents classified in any of the SIC or NAICS codes 
listed in paragraph (b)(1)(i) or (ii) of this section that are recovered 
using nondedicated solvent recovery operations.
    (2) The MCPU processes, uses, or generates any of the organic HAP 
listed in section 112(b) of the CAA or hydrogen halide and halogen HAP, 
as defined in Sec. 63.2550.
    (3) The MCPU is not an affected source or part of an affected source 
under another subpart of this part 63, except for process vents from 
batch operations within a chemical manufacturing process unit (CMPU), as 
identified in Sec. 63.100(j)(4). For this situation, the MCPU is the 
same as the CMPU as defined in Sec. 63.100, and you are subject only to 
the requirements for batch process vents in this subpart.
    (c) The requirements in this subpart do not apply to the operations 
specified in paragraphs (c)(1) through (7) of this section.
    (1) Research and development facilities, as defined in section 
112(c)(7) of the CAA.
    (2) The manufacture of ammonium sulfate as a by-product, if the 
slurry entering the by-product manufacturing process contains 50 parts 
per million by weight (ppmw) HAP or less or 10 ppmw benzene or less. You 
must retain information, data, and analysis to document the HAP 
concentration in the entering slurry in order to claim this exemption.
    (3) The affiliated operations located at an affected source under 
subparts GG (National Emission Standards for Aerospace Manufacturing and 
Rework Facilities), KK (National Emission Standards for the Printing and 
Publishing Industry), JJJJ (NESHAP: Paper and Other Web Coating), future 
MMMM (NESHAP: Surface Coating of Miscellaneous Metal Parts and 
Products), and SSSS (NESHAP: Surface Coating of Metal Coil) of this part 
63. Affiliated operations include, but are not limited to, mixing or 
dissolving of coating ingredients; coating mixing for viscosity 
adjustment, color tint or additive blending, or pH adjustment; cleaning 
of coating lines and coating line parts; handling and storage of 
coatings and solvent; and conveyance and treatment of wastewater.
    (4) Fabricating operations (such as spinning or compressing a solid 
polymer into its end use); compounding operations (in which blending, 
melting, and resolidification of a solid polymer product occur for the 
purpose of incorporating additives, colorants, or stabilizers); and 
extrusion and drawing operations (converting an already produced solid 
polymer into a different shape by melting or mixing the polymer and then 
forcing it or pulling it through an orifice to create an extruded 
product). An operation is not exempt if it involves processing with HAP 
solvent or if an intended purpose of the operation is to remove residual 
HAP monomer.
    (5) Production activities described using the 1997 version of NAICS 
codes 325131, 325181, 325188 (except the requirements do apply to 
hydrazine), 325314, 325991 (except the requirements do apply to 
reformulating plastics resins from recycled plastics products), and 
325992 (except the requirements do apply to photographic chemicals).
    (6) Tall oil recovery systems.
    (7) Carbon monoxide production.
    (d) If the predominant use of a transfer rack loading arm or storage 
tank (including storage tanks in series) is associated with a 
miscellaneous organic chemical manufacturing process, and the loading 
arm or storage tank is not part of an affected source under a subpart of 
this part 63, then you must

[[Page 328]]

assign the loading arm or storage tank to the MCPU for that 
miscellaneous organic chemical manufacturing process. If the predominant 
use cannot be determined, then you may assign the loading arm or storage 
tank to any MCPU that shares it and is subject to this subpart. If the 
use varies from year to year, then you must base the determination on 
the utilization that occurred during the year preceding November 10, 
2003 or, if the loading arm or storage tank was not in operation during 
that year, you must base the use on the expected use for the first 5-
year period after startup. You must include the determination in the 
notification of compliance status report specified in Sec. 63.2520(d). 
You must redetermine the primary use at least once every 5 years, or any 
time you implement emissions averaging or pollution prevention after the 
compliance date.
    (e) For nondedicated equipment used to create at least one MCPU, you 
may elect to develop process unit groups (PUG), determine the primary 
product of each PUG, and comply with the requirements of the subpart in 
40 CFR part 63 that applies to that primary product as specified in 
Sec. 63.2535(l).

[68 FR 63888, Nov. 10, 2003, as amended at 71 FR 40331, July 14, 2006]



Sec. 63.2440  What parts of my plant does this subpart cover?

    (a) This subpart applies to each miscellaneous organic chemical 
manufacturing affected source.
    (b) The miscellaneous organic chemical manufacturing affected source 
is the facilitywide collection of MCPU and heat exchange systems, 
wastewater, and waste management units that are associated with 
manufacturing materials described in Sec. 63.2435(b)(1).
    (c) A new affected source is described by either paragraph (c)(1) or 
(2) of this section.
    (1) Each affected source defined in paragraph (b) of this section 
for which you commenced construction or reconstruction after April 4, 
2002, and you meet the applicability criteria at the time you commenced 
construction or reconstruction.
    (2) Each dedicated MCPU that has the potential to emit 10 tons per 
year (tpy) of any one HAP or 25 tpy of combined HAP, and you commenced 
construction or reconstruction of the MCPU after April 4, 2002. For the 
purposes of this paragraph, an MCPU is an affected source in the 
definition of the term ``reconstruction'' in Sec. 63.2.
    (d) An MCPU that is also a CMPU under Sec. 63.100 is reconstructed 
for the purposes of this subpart if, and only if, the CMPU meets the 
requirements for reconstruction in Sec. 63.100(l)(2).

                            Compliance Dates



Sec. 63.2445  When do I have to comply with this subpart?

    (a) If you have a new affected source, you must comply with this 
subpart according to the requirements in paragraphs (a)(1) and (2) of 
this section.
    (1) If you startup your new affected source before November 10, 
2003, then you must comply with the requirements for new sources in this 
subpart no later than November 10, 2003.
    (2) If you startup your new affected source after November 10, 2003, 
then you must comply with the requirements for new sources in this

FR 40332, July 14, 2006]

  Emission Limits, Work Practice Standards, and Compliance Requirements



Sec. 63.2450  What are my general requirements for complying with 
this subpart?

    (a) You must be in compliance with the emission limits and work 
practice standards in tables 1 through 7 to this subpart at all times, 
except during periods of startup, shutdown, and malfunction (SSM), and 
you must meet the requirements specified in Sec. Sec. 63.2455 through 
63.2490 (or the alternative means of compliance in Sec. 63.2495, Sec. 
63.2500, or Sec. 63.2505), except as specified in paragraphs (b) 
through (s) of this section. You must meet the notification, reporting, 
and recordkeeping requirements specified in Sec. Sec. 63.2515, 63.2520, 
and 63.2525.
    (b) Determine halogenated vent streams. You must determine if an 
emission stream is a halogenated vent stream, as defined in Sec. 
63.2550, by calculating the mass emission rate of halogen atoms in 
accordance with Sec. 63.115(d)(2)(v). Alternatively, you may elect to 
designate the emission stream as halogenated.
    (c) Requirements for combined emission streams. When organic HAP 
emissions from different emission types (e.g., continuous process vents, 
batch process vents, storage tanks, transfer operations, and waste 
management units) are combined, you must comply with the requirements of 
either paragraph (c)(1) or (2) of this section.
    (1) Comply with the applicable requirements of this subpart for each 
kind of organic HAP emissions in the stream (e.g., the requirements of 
table 1 to this subpart for continuous process vents and the 
requirements of table 4 to this subpart for emissions from storage 
tanks).
    (2) Determine the applicable requirements based on the hierarchy 
presented in paragraphs (c)(2)(i) through (vi) of this section. For a 
combined stream, the applicable requirements are specified in the 
highest-listed paragraph in the hierarchy that applies to any of the 
individual streams that make up the combined stream. For example, if a 
combined stream consists of emissions from Group 1 batch process vents 
and any other type of emission stream, then you must comply with the 
requirements in paragraph (c)(2)(i) of this section for the combined 
stream; compliance with the requirements in paragraph (c)(2)(i) of this 
section constitutes compliance for the other emission streams in the 
combined stream. Two exceptions are that you must comply with the 
requirements in table 3 to this subpart and Sec. 63.2465 for all 
process vents with hydrogen halide and halogen HAP emissions, and 
recordkeeping requirements for Group 2 applicability or compliance are 
still required (e.g., the requirement in Sec. 63.2525(f) to track the 
number of batches produced and calculate rolling annual emissions for 
processes with Group 2 batch process vents).
    (i) The requirements of table 2 to this subpart and Sec. 63.2460 
for Group 1 batch process vents, including applicable monitoring, 
recordkeeping, and reporting.
    (ii) The requirements of table 1 to this subpart and Sec. 63.2455 
for continuous process vents that are routed to a control device, as 
defined in Sec. 63.981, including applicable monitoring, recordkeeping, 
and reporting.

[[Page 330]]

    (iii) The requirements of table 5 to this subpart and Sec. 63.2475 
for transfer operations, including applicable monitoring, recordkeeping, 
and reporting.
    (iv) The requirements of table 7 to this subpart and Sec. 63.2485 
for emissions from waste management units that are used to manage and 
treat Group 1 wastewater streams and residuals from Group 1 wastewater 
streams, including applicable monitoring, recordkeeping, and reporting.
    (v) The requirements of table 4 to this subpart and Sec. 63.2470 
for control of emissions from storage tanks, including applicable 
monitoring, recordkeeping, and reporting.
    (vi) The requirements of table 1 to this subpart and Sec. 63.2455 
for continuous process vents after a recovery device including 
applicable monitoring, recordkeeping, and reporting.
    (d) [Reserved]
    (e) Requirements for control devices. (1) Except when complying with 
Sec. 63.2485, if you reduce organic HAP emissions by venting emissions 
through a closed-vent system to any combination of control devices 
(except a flare) or recovery devices, you must meet the requirements of 
Sec. 63.982(c) and the requirements referenced therein.
    (2) Except when complying with Sec. 63.2485, if you reduce organic 
HAP emissions by venting emissions through a closed-vent system to a 
flare, you must meet the requirements of Sec. 63.982(b) and the 
requirements referenced therein.
    (3) If you use a halogen reduction device to reduce hydrogen halide 
and halogen HAP emissions from halogenated vent streams, you must meet 
the requirements of Sec. 63.994 and the requirements referenced 
therein. If you use a halogen reduction device before a combustion 
device, you must determine the halogen atom emission rate prior to the 
combustion device according to the procedures in Sec. 63.115(d)(2)(v).
    (f) Requirements for flare compliance assessments. (1) As part of a 
flare compliance assessment required in Sec. 63.987(b), you have the 
option of demonstrating compliance with the requirements of Sec. 
63.11(b) by complying with the requirements in either Sec. 
63.11(b)(6)(i) or Sec. 63.987(b)(3)(ii).
    (2) If you elect to meet the requirements in Sec. 63.11(b)(6)(i), 
you must keep flare compliance assessment records as specified in 
paragraphs (f)(2)(i) and (ii) of this section.
    (i) Keep records as specified in Sec. 63.998(a)(1)(i), except that 
a record of the heat content determination is not required.
    (ii) Keep records of the flare diameter, hydrogen content, exit 
velocity, and maximum permitted velocity. Include these records in the 
flare compliance report required in Sec. 63.999(a)(2).
    (g) Requirements for performance tests. The requirements specified 
in paragraphs (g)(1) through (5) of this section apply instead of or in 
addition to the requirements specified in subpart SS of this part 63.
    (1) Conduct gas molecular weight analysis using Method 3, 3A, or 3B 
in appendix A to part 60 of this chapter.
    (2) Measure moisture content of the stack gas using Method 4 in 
appendix A to part 60 of this chapter.
    (3) If the uncontrolled or inlet gas stream to the control device 
contains carbon disulfide, you must conduct emissions testing according 
to paragraph (g)(3)(i) or (ii) of this section.
    (i) If you elect to comply with the percent reduction emission 
limits in tables 1 through 7 to this subpart, and carbon disulfide is 
the principal organic HAP component (i.e., greater than 50 percent of 
the HAP in the stream by volume), then you must use Method 18, or Method 
15 (40 CFR part 60, appendix A) to measure carbon disulfide at the inlet 
and outlet of the control device. Use the percent reduction in carbon 
disulfide as a surrogate for the percent reduction in total organic HAP 
emissions.
    (ii) If you elect to comply with the outlet total organic compound 
(TOC) concentration emission limits in tables 1 through 7 to this 
subpart, and the uncontrolled or inlet gas stream to the control device 
contains greater than 10 percent (volume concentration) carbon 
disulfide, you must use Method 18 or Method 15 to separately determine 
the carbon disulfide concentration. Calculate the total HAP or TOC 
emissions by totaling the carbon disulfide emissions measured using 
Method 18 or 15

[[Page 331]]

and the other HAP emissions measured using Method 18 or 25A.
    (4) As an alternative to using Method 18, Method 25/25A, or Method 
26/26A of 40 CFR part 60, appendix A, to comply with any of the emission 
limits specified in tables 1 through 7 to this subpart, you may use 
Method 320 of 40 CFR part 60, appendix A. When using Method 320, you 
must follow the analyte spiking procedures of section 13 of Method 320, 
unless you demonstrate that the complete spiking procedure has been 
conducted at a similar source.
    (5) Section 63.997(c)(1) does not apply. For the purposes of this 
subpart, results of all initial compliance demonstrations must be 
included in the notification of compliance status report, which is due 
150 days after the compliance date, as specified in Sec. 63.2520(d)(1).
    (h) Design evaluation. To determine the percent reduction of a small 
control device that is used to comply with an emission limit specified 
in table 1, 2, 3, or 5 to this subpart, you may elect to conduct a 
design evaluation as specified in Sec. 63.1257(a)(1) instead of a 
performance test as specified in subpart SS of this part 63. You must 
establish the value(s) and basis for the operating limits as part of the 
design evaluation. For continuous process vents, the design evaluation 
must be conducted at maximum representative operating conditions for the 
process, unless the Administrator specifies or approves alternate 
operating conditions. For transfer racks, the design evaluation must 
demonstrate that the control device achieves the required control 
efficiency during the reasonably expected maximum transfer loading rate.
    (i) Outlet concentration correction for combustion devices. When 
Sec. 63.997(e)(2)(iii)(C) requires you to correct the measured 
concentration at the outlet of a combustion device to 3 percent oxygen 
if you add supplemental combustion air, the requirements in either 
paragraph (i)(1) or (2) of this section apply for the purposes of this 
subpart.
    (1) You must correct the concentration in the gas stream at the 
outlet of the combustion device to 3 percent oxygen if you add 
supplemental gases, as defined in Sec. 63.2550, to the vent stream, or;
    (2) You must correct the measured concentration for supplemental 
gases using Equation 1 of Sec. 63.2460; you may use process knowledge 
and representative operating data to determine the fraction of the total 
flow due to supplemental gas.
    (j) Continuous emissions monitoring systems. Each continuous 
emissions monitoring system (CEMS) must be installed, operated, and 
maintained according to the requirements in Sec. 63.8 and paragraphs 
(j)(1) through (5) of this section.
    (1) Each CEMS must be installed, operated, and maintained according 
to the applicable Performance Specification of 40 CFR part 60, appendix 
B, and according to paragraph (j)(2) of this section, except as 
specified in paragraph (j)(1)(i) of this section. For any CEMS meeting 
Performance Specification 8, you must also comply with appendix F, 
procedure 1 of 40 CFR part 60.
    (i) If you wish to use a CEMS other than an Fourier Transform 
Infrared Spectroscopy (FTIR) meeting the requirements of Performance 
Specification 15 to measure hydrogen halide and halogen HAP before we 
promulgate a Performance Specification for such CEMS, you must prepare a 
monitoring plan and submit it for approval in accordance with the 
procedures specified in Sec. 63.8.
    (ii) [Reserved]
    (2) You must determine the calibration gases and reporting units for 
TOC CEMS in accordance with paragraph (j)(2)(i), (ii), or (iii) of this 
section.
    (i) For CEMS meeting Performance Specification 9 or 15 requirements, 
determine the target analyte(s) for calibration using either process 
knowledge of the control device inlet stream or the screening procedures 
of Method 18 on the control device inlet stream.
    (ii) For CEMS meeting Performance Specification 8 used to monitor 
performance of a combustion device, calibrate the instrument on the 
predominant organic HAP and report the results as carbon (C1), and use 
Method 25A or any approved alternative as the reference method for the 
relative accuracy tests.
    (iii) For CEMS meeting Performance Specification 8 used to monitor 
performance of a noncombustion device,

[[Page 332]]

determine the predominant organic HAP using either process knowledge or 
the screening procedures of Method 18 on the control device inlet 
stream, calibrate the monitor on the predominant organic HAP, and report 
the results as C1. Use Method 18, ASTM D6420-99, or any 
approved alternative as the reference method for the relative accuracy 
tests, and report the results as C1.
    (3) You must conduct a performance evaluation of each CEMS according 
to the requirements in 40 CFR 63.8 and according to the applicable 
Performance Specification of 40 CFR part 60, appendix B, except that the 
schedule in Sec. 63.8(e)(4) does not apply, and the results of the 
performance evaluation must be included in the notification of 
compliance status report.
    (4) The CEMS data must be reduced to operating day or operating 
block averages computed using valid data consistent with the data 
availability requirements specified in Sec. 63.999(c)(6)(i)(B) through 
(D), except monitoring data also are sufficient to constitute a valid 
hour of data if measured values are available for at least two of the 
15-minute periods during an hour when calibration, quality assurance, or 
maintenance activities are being performed. An operating block is a 
period of time from the beginning to end of batch operations within a 
process. Operating block averages may be used only for batch process 
vent data.
    (5) If you add supplemental gases, you must correct the measured 
concentrations in accordance with paragraph (i) of this section and 
Sec. 63.2460(c)(6).
    (k) Continuous parameter monitoring. The provisions in paragraphs 
(k)(1) through (6) of this section apply in addition to the requirements 
for continuous parameter monitoring system (CPMS) in subpart SS of this 
part 63.
    (1) You must record the results of each calibration check and all 
maintenance performed on the CPMS as specified in Sec. 
63.998(c)(1)(ii)(A).
    (2) When subpart SS of this part 63 uses the term ``a range'' or 
``operating range'' of a monitored parameter, it means an ``operating 
limit'' for a monitored parameter for the purposes of this subpart.
    (3) As an alternative to continuously measuring and recording pH as 
specified in Sec. Sec. 63.994(c)(1)(i) and 63.998(a)(2)(ii)(D), you may 
elect to continuously monitor and record the caustic strength of the 
effluent. For halogen scrubbers used to control only batch process vents 
you may elect to monitor and record either the pH or the caustic 
strength of the scrubber effluent at least once per day.
    (4) As an alternative to the inlet and outlet temperature monitoring 
requirements for catalytic incinerators as specified in Sec. 
63.988(c)(2) and the related recordkeeping requirements specified in 
Sec. 63.998(a)(2)(ii)(B)(2) and (c)(2)(ii), you may elect to comply

this section.
    (i) Monitor and record the inlet temperature as specified in subpart 
SS of this part 63.
    (ii) Check the activity level of the catalyst at least every 12 
months and take any necessary corrective action, such as replacing the 
catalyst to ensure that the catalyst is performing as designed.
    (iii) Maintain records of the annual checks of catalyst activity 
levels and the subsequent corrective actions.
    (iv) Recording the downstream temperature and temperature difference 
across the catalyst bed as specified in Sec. 63.998(a)(2)(ii)(B)(2) and 
(b)(2)(ii) is not required.
    (5) For absorbers that control organic compounds and use water as 
the scrubbing fluid, you must conduct monitoring and recordkeeping as 
specified in paragraphs (k)(5)(i) through (iii) of this section instead 
of the monitoring and recordkeeping requirements specified in Sec. Sec. 
63.990(c)(1), 63.993(c)(1), and 63.998(a)(2)(ii)(C).
    (i) You must use a flow meter capable of providing a continuous 
record of the absorber influent liquid flow.
    (ii) You must determine gas stream flow using one of the procedures 
specified in Sec. 63.994(c)(1)(ii)(A) through (D).
    (iii) You must record the absorber liquid-to-gas ratio averaged over 
the time period of any performance test.
    (6) For a control device with total inlet HAP emissions less than 1 
tpy, you must establish an operating

[[Page 333]]

limit(s) for a parameter(s) that you will measure and record at least 
once per averaging period (i.e., daily or block) to verify that the 
control device is operating properly. You may elect to measure the same 
parameter(s) that is required for control devices that control inlet HAP 
emissions equal to or greater than 1 tpy. If the parameter will not be 
measured continuously, you must request approval of your proposed 
procedure in the precompliance report. You must identify the operating 
limit(s) and the measurement frequency, and you must provide rationale 
to support how these measurements demonstrate the control device is 
operating properly.
    (l) Startup, shutdown, and malfunction. Sections 63.152(f)(7)(ii) 
through (iv) and 63.998(b)(2)(iii) and (b)(6)(i)(A), which apply to the 
exclusion of monitoring data collected during periods of SSM from daily 
averages, do not apply for the purposes of this subpart.
    (m) Reporting. (1) When Sec. Sec. 63.2455 through 63.2490 reference 
other subparts in this part 63 that use the term ``periodic report,'' it 
means ``compliance report'' for the purposes of this subpart. The 
compliance report must include the information specified in Sec. 
63.2520(e), as well as the information specified in referenced subparts.
    (2) When there are conflicts between this subpart and referenced 
subparts for the due dates of reports required by this subpart, reports 
must be submitted according to the due dates presented in this subpart.
    (3) Excused excursions, as defined in subparts G and SS of this part 
63, are not allowed.
    (n) [Reserved]
    (o) You may not use a flare to control halogenated vent streams or 
hydrogen halide and halogen HAP emissions.
    (p) Opening a safety device, as defined in Sec. 63.2550, is allowed 
at any time conditions require it to avoid unsafe conditions.
    (q) If an emission stream contains energetics or organic peroxides 
that, for safety reasons, cannot meet an applicable emission limit 
specified in Tables 1 through 7 to this subpart, then you must submit 
documentation in your precompliance report explaining why an undue 
safety hazard would be created if the air emission controls were 
installed, and you must describe the procedures that you will implement 
to minimize HAP emissions from these vent streams.
    (r) Surge control vessels and bottoms receivers. For each surge 
control vessel or bottoms receiver that meets the capacity and vapor 
pressure thresholds for a Group 1 storage tank, you must meet emission 
limits and work practice standards specified in Table 4 to this subpart.
    (s) For the purposes of determining Group status for continuous 
process vents, batch process vents, and storage tanks in Sec. Sec. 
63.2455, 63.2460, and 63.2470, hydrazine is to be considered an organic 
HAP.

FR 40332, July 14, 2006]



Sec. 63.2455  What requirements must I meet for continuous process vents?

    (a) You must meet each emission limit in Table 1 to this subpart 
that applies to your continuous process vents, and you must meet each 
applicable requirement specified in paragraphs (b) through (c) of this 
section.
    (b) For each continuous process vent, you must either designate the 
vent as a Group 1 continuous process vent or determine the total 
resource effectiveness (TRE) index value as specified in Sec. 
63.115(d), except as specified in paragraphs (b)(1) through (3) of this 
section.
    (1) You are not required to determine the Group status or the TRE 
index value for any continuous process vent that is combined with Group 
1 batch process vents before a control device or recovery device because 
the requirements of Sec. 63.2450(c)(2)(i) apply to the combined stream.
    (2) When a TRE index value of 4.0 is referred to in Sec. 63.115(d), 
TRE index values of 5.0 for existing affected sources and 8.0 for new 
and reconstructed affected sources apply for the purposes of this 
subpart.
    (3) When Sec. 63.115(d) refers to ``emission reductions specified 
in Sec. 63.113(a),'' the reductions specified in Table 1 to this 
subpart apply for the purposes of this subpart.

[[Page 334]]

    (c) If you use a recovery device to maintain the TRE above a 
specified threshold, you must meet the requirements of Sec. 63.982(e) 
and the requirements referenced therein, except as specified in Sec. 
63.2450 and paragraph (c)(1) of this section.
    (1) When Sec. 63.993 uses the phrase ``the TRE index value is 
between the level specified in a referencing subpart and 4.0,'' the 
phrase ``the TRE index value is 1.9 but <=5.0'' applies for 
an existing affected source, and the phrase ``the TRE index value is 
5.0 but <=8.0'' applies for a new and reconstructed affected 
source, for the purposes of this subpart.
    (2) [Reserved]



Sec. 63.2460  What requirements must I meet for batch process vents?

    (a) You must meet each emission limit in Table 2 to this subpart 
that applies to you, and you must meet each applicable requirement 
specified in paragraphs (b) and (c) of this section.
    (b) Group status. If a process has batch process vents, as defined 
in Sec. 63.2550, you must determine the group status of the batch 
process vents by determining and summing the uncontrolled organic HAP 
emissions from each of the batch process vents within the process using 
the procedures specified in Sec. 63.1257(d)(2)(i) and (ii), except as 
specified in paragraphs (b)(1) through (7) of this section.
    (1) To calculate emissions caused by the heating of a vessel without 
a process condenser to a temperature lower than the boiling point, you 
must use the procedures in Sec. 63.1257(d)(2)(i)(C)(3).
    (2) To calculate emissions from depressurization of a vessel without 
a process condenser, you must use the procedures in Sec. 
63.1257(d)(2)(i)(D)(10).
    (3) To calculate emissions from vacuum systems for the purposes of 
this subpart, the receiving vessel is part of the vacuum system, and 
terms used in Equation 33 to 40 CFR part 63, subpart GGG, are defined as 
follows:

Psystem = absolute pressure of the receiving vessel;
Pi = partial pressure of the HAP determined at the exit 
temperature and exit pressure conditions of the condenser or at the 
conditions of the dedicated receiver;
Pj = partial pressure of condensables (including HAP) 
determined at the exit temperature and exit pressure conditions of the 
condenser or at the conditions of the dedicated receiver;
MWHAP = molecular weight of the HAP determined at the exit 
temperature and exit pressure conditions of the condenser or at the 
conditions of the dedicated receiver.

    (4) To calculate uncontrolled emissions when a vessel is equipped 
with a process condenser, you must use the procedures in Sec. 
63.1257(d)(3)(i)(B), except as specified in paragraphs (b)(4)(i) through 
(vii) of this section.
    (i) You must determine the flowrate of gas (or volume of gas), 
partial pressures of condensables, temperature (T), and HAP molecular 
weight (MWHAP) at the exit temperature and exit pressure 
conditions of the condenser or at the conditions of the dedicated 
receiver.
    (ii) You must assume that all of the components contained in the 
condenser exit vent stream are in equilibrium with the same components 
in the exit condensate stream (except for noncondensables).
    (iii) You must perform a material balance for each component.
    (iv) For the emissions from gas evolution, the term for time, t, 
must be used in Equation 12 to 40 CFR part 63, subpart GGG.
    (v) Emissions from empty vessel purging shall be calculated using 
Equation 36 to 40 CFR part 63, subpart GGG and the exit temperature and 
exit pressure conditions of the condenser or the conditions of the 
dedicated receiver.
    (vi) You must conduct an engineering assessment as specified in 
Sec. 63.1257(d)(2)(ii) for each emission episode that is not due to 
vapor displacement, purging, heating, depressurization, vacuum 
operations, gas evolution, air drying, or empty vessel purging. The 
requirements of paragraphs (b)(3) through (4) of this section shall 
apply.
    (vii) You may elect to conduct an engineering assessment if you can 
demonstrate to the Administrator that the methods in Sec. 
63.1257(d)(3)(i)(B) are not appropriate.
    (5) You may elect to designate the batch process vents within a 
process as Group 1 and not calculate uncontrolled

[[Page 335]]

emissions under either of the situations in paragraph (b)(5)(i), (ii), 
or (iii) of this section.
    (i) If you comply with the alternative standard specified in Sec. 
63.2505.
    (ii) If all Group 1 batch process vents within a process are 
controlled; you conduct the performance test under hypothetical worst 
case conditions, as defined in Sec. 63.1257(b)(8)(i)(B); and the 
emission profile is based on capture and control system limitations as 
specified in Sec. 63.1257(b)(8)(ii)(C).
    (iii) If you comply with an emission limit using a flare that meets 
the requirements specified in Sec. 63.987.
    (6) You may change from Group 2 to Group 1 in accordance with either 
paragraph (b)(6)(i) or (ii) of this section. You must comply with the 
requirements of this section and submit the test report in the next 
Compliance report.
    (i) You may switch at any time after operating as Group 2 for at 
least 1 year so that you can show compliance with the 10,000 pounds per 
year (lb/yr) threshold for Group 2 batch process vents for at least 365 
days before the switch. You may elect to start keeping records of 
emissions from Group 2 batch process vents before the compliance date. 
Report a switch based on this provision in your next compliance report 
in accordance with Sec. 63.2520(e)(10)(i).
    (ii) If the conditions in paragraph (b)(6)(i) of this section are 
not applicable, you must provide a 60-day advance notice in accordance 
with Sec. 63.2520(e)(10)(ii) before switching.
    (7) As an alternative to determining the uncontrolled organic HAP 
emissions as specified in Sec. 63.1257(d)(2)(i) and (ii), you may elect 
to demonstrate that non-reactive organic HAP are the only HAP used in 
the process and non-reactive HAP usage in the process is less than 
10,000 lb/yr. You must provide data and supporting rationale in your 
notification of compliance status report explaining why the non-reactive 
organic HAP usage will be less than 10,000 lb/yr. You must keep records 
of the non-reactive organic HAP usage as specified in Sec. 
63.2525(e)(2) and include information in compliance reports as specified 
in Sec. 63.2520(e)(5)(iv).
    (c) Exceptions to the requirements in subparts SS and WW of this 
part 63 are specified in paragraphs (c)(1) through (9) of this section.
    (1) Process condensers. Process condensers, as defined in Sec. 
63.2550(i), are not considered to be control devices for batch process 
vents. You must determine whether a condenser is a control device for a 
batch process vent or a process condenser from which the uncontrolled 
HAP emissions are evaluated as part of the initial compliance 
demonstration for each MCPU and report the results with supporting 
rationale in your notification of compliance status report.
    (2) Initial compliance. (i) To demonstrate initial compliance with a 
percent reduction emission limit in Table 2 to this subpart FFFF, you 
must compare the sums of the controlled and uncontrolled emissions for 
the applicable Group 1 batch process vents within the process, and show 
that the specified reduction is met. This requirement does not apply if 
you comply with the emission limits of Table 2 to this subpart FFFF by 
using a flare that meets the requirements of Sec. 63.987.
    (ii) When you conduct a performance test or design evaluation for a 
non-flare control device used to control emissions from batch process 
vents, you must establish emission profiles and conduct the test under 
worst-case conditions according to Sec. 63.1257(b)(8) instead of under 
normal operating conditions as specified in Sec. 63.7(e)(1). The 
requirements in Sec. 63.997(e)(1)(i) and (iii) also do not apply for 
performance tests conducted to determine compliance with the emission 
limits for batch process vents. For purposes of this subpart FFFF, 
references in Sec. 63.997(b)(1) to ``methods specified in Sec. 
63.997(e)'' include the methods specified in Sec. 63.1257(b)(8).
    (iii) As an alternative to conducting a performance test or design 
evaluation to demonstrate initial compliance with a percent reduction 
requirement for a condenser, you may determine controlled emissions 
using the procedures specified in Sec. 63.1257(d)(3)(i)(B) and 
paragraphs (b)(3) through (4) of this section.

[[Page 336]]

    (iv) When Sec. 63.1257(d)(3)(i)(B)(7) specifies that condenser-
controlled emissions from an air dryer must be calculated using Equation 
11 of 40 CFR part 63, subpart GGG, with ``V equal to the air flow 
rate,'' it means ``V equal to the dryer outlet gas flow rate,'' for the 
purposes of this subpart. Alternatively, you may use Equation 12 of 40 
CFR part 63, subpart GGG, with V equal to the dryer inlet air flow rate. 
Account for time as appropriate in either equation.
    (v) If a process condenser is used for any boiling operations, you 
must demonstrate that it is properly operated according to the 
procedures specified in Sec. 63.1257(d)(2)(i)(C)(4)(ii) and 
(d)(3)(iii)(B), and the demonstration must occur only during the boiling 
operation. The reference in Sec. 63.1257(d)(3)(iii)(B) to the 
alternative standard in Sec. 63.1254(c) means Sec. 63.2505 for the 
purposes of this subpart. As an alternative to measuring the exhaust gas 
temperature, as required by Sec. 63.1257(d)(3)(iii)(B), you may elect 
to measure the liquid temperature in the receiver.
    (vi) You must conduct a subsequent performance test or compliance 
demonstration equivalent to an initial compliance demonstration within 
180 days of a change in the worst-case conditions.
    (3) Establishing operating limits. You must establish operating 
limits under the conditions required for your initial compliance 
demonstration, except you may elect to establish operating limit(s) for 
conditions other than those under which a performance test was conducted 
as specified in paragraph (c)(3)(i) of this section and, if applicable, 
paragraph (c)(3)(ii) of this section.
    (i) The operating limits may be based on the results of the 
performance test and supplementary information such as engineering 
assessments and manufacturer's recommendations. These limits may be 
established for conditions as unique as individual emission episodes for 
a batch process. You must provide rationale in the precompliance report 
for the specific level for each operating limit, including any data and 
calculations used to develop the limit and a description of why the 
limit indicates proper operation of the control device. The procedures 
provided in this paragraph (c)(3)(i) have not been approved by the 
Administrator and determination of the operating limit using these 
procedures is subject to review and approval by the Administrator.
    (ii) If you elect to establish separate monitoring levels for 
different emission episodes within a batch process, you must maintain 
records in your daily schedule or log of processes indicating each point 
at which you change from one operating limit to another, even if the 
duration of the monitoring for an operating limit is less than 15 
minutes. You must maintain a daily schedule or log of processes 
according to Sec. 63.2525(c).
    (4) Averaging periods. As an alternative to the requirement for 
daily averages in Sec. 63.998(b)(3), you may determine averages for 
operating blocks. An operating block is a period of time that is equal 
to the time from the beginning to end of batch process operations within 
a process.
    (5) [Reserved]
    (6) Outlet concentration correction for supplemental gases. If you 
use a control device other than a combustion device to comply with a 
TOC, organic HAP, or hydrogen halide and halogen HAP outlet 
concentration emission limit for batch process vents, you must correct 
the actual concentration for supplemental gases using Equation 1 of this 
section; you may use process knowledge and representative operating data 
to determine the fraction of the total flow due to supplemental gas.
[GRAPHIC] [TIFF OMITTED] TR10NO03.000

Where:

Ca = corrected outlet TOC, organic HAP, or hydrogen halide 
          and halogen HAP concentration, dry basis, ppmv;
Cm = actual TOC, organic HAP, or hydrogen halide and halogen 
          HAP concentration measured at control device outlet, dry 
          basis, ppmv;
Qa = total volumetric flowrate of all gas streams vented to 
          the control device, except supplemental gases;
Qs = total volumetric flowrate of supplemental gases.

    (7) If flow to a control device could be intermittent, you must 
install, calibrate, and operate a flow indicator at

[[Page 337]]

the inlet or outlet of the control device to identify periods of no 
flow. Periods of no flow may not be used in daily or block averages, and 
it may not be used in fulfilling a minimum data availability 
requirement.
    (8) Terminology. When the term ``storage vessel'' is used in subpart 
WW of this part 63, the term ``process tank,'' as defined in Sec. 
63.2550(i), applies for the purposes of this section.
    (9) Requirements for a biofilter. If you use a biofilter to meet 
either the 95 percent reduction requirement or outlet concentration 
requirement specified in Table 2 to this subpart, you must meet the 
requirements specified in paragraphs (c)(9)(i) through (iv) of this 
section.
    (i) Operational requirements. The biofilter must be operated at all 
times when emissions are vented to it.
    (ii) Performance tests. To demonstrate initial compliance, you must 
conduct a performance test according to the procedures in Sec. 63.997 
and paragraphs (c)(9)(ii)(A) through (D) of this section. The design 
evaluation option for small control devices is not applicable if you use 
a biofilter.
    (A) Keep up-to-date, readily accessible continuous records of either 
the biofilter bed temperature averaged over the full period of the 
performance test or the outlet total organic HAP or TOC concentration 
averaged over the full period of the performance test. Include these 
data in your notification of compliance status report as required by 
Sec. 63.999(b)(3)(ii).
    (B) Record either the percent reduction of total organic HAP 
achieved by the biofilter determined as specified in Sec. 
63.997(e)(2)(iv) or the concentration of TOC or total organic HAP 
determined as specified in Sec. 63.997(e)(2)(iii) at the outlet of the 
biofilter, as applicable.
    (C) If you monitor the biofilter bed temperature, you may elect to 
use multiple thermocouples in representative locations throughout the 
biofilter bed and calculate the average biofilter bed temperature across 
these thermocouples prior to reducing the temperature data to 15 minute 
(or shorter) averages for purposes of establishing operating limits for 
the biofilter. If you use multiple thermocouples, include your rationale 
for their site selection in your notification of compliance status 
report.
    (D) Submit a performance test report as specified in Sec. 
63.999(a)(2)(i) and (ii). Include the records from paragraph 
(c)(9)(ii)(B) of this section in your performance test report.
    (iii) Monitoring requirements. Use either a biofilter bed 
temperature monitoring device (or multiple devices) capable of providing 
a continuous record or an organic monitoring device capable of providing 
a continuous record. Keep records of temperature or other parameter 
monitoring results as specified in Sec. 63.998(b) and (c), as 
applicable. General requirements for monitoring are contained in Sec. 
63.996. If you monitor temperature, the operating temperature range must 
be based on only the temperatures measured during the performance test; 
these data may not be supplemented by engineering assessments or 
manufacturer's recommendations as otherwise allowed in Sec. 
63.999(b)(3)(ii)(A). If you establish the operating range (minimum and 
maximum temperatures) using data from previous performance tests in 
accordance with Sec. 63.996(c)(6), replacement of the biofilter media 
with the same type of media is not considered a process change under 
Sec. 63.997(b)(1). You may expand your biofilter bed temperature 
operating range by conducting a repeat performance test that 
demonstrates compliance with the 95 percent reduction requirement or 
outlet concentration limit, as applicable.
    (iv) Repeat performance tests. You must conduct a repeat performance 
test using the applicable methods specified in Sec. 63.997 within 2 
years following the previous performance test and within 150 days after 
each replacement of any portion of the biofilter bed media with a 
different type of media or each replacement of more than 50 percent (by 
volume) of the biofilter bed media with the same type of media.

Sec. 63.2465  What requirements must I meet for process vents that
emit hydrogen halide and halogen HAP or HAP metals?

    (a) You must meet each emission limit in Table 3 to this subpart 
that applies to you, and you must meet each applicable requirement in 
paragraphs (b) through (d) of this section.
    (b) If any process vents within a process emit hydrogen halide and 
halogen HAP, you must determine and sum the uncontrolled hydrogen halide 
and halogen HAP emissions from each of the process vents within the 
process using the procedures specified in Sec. 63.1257(d)(2)(i) and/or

(HAP factor) by at least 65 percent from a 3-year average baseline 
beginning no earlier than the 1994 through 1996 calendar years. For any 
reduction in the HAP factor that you achieve by reducing HAP that are 
also volatile organic compounds (VOC), you must demonstrate an 
equivalent reduction in the production-indexed VOC consumption factor 
(VOC factor) on a mass basis. For any reduction in the HAP factor that 
you achieve by reducing a HAP that is not a VOC, you may not increase 
the VOC factor.
    (2) Any MCPU for which you seek to comply by using the pollution 
prevention alternative must begin with the same starting material(s) and 
end with the same product(s). You may not comply by eliminating any 
steps of a process by transferring the step offsite (to another 
manufacturing location). You may also not merge a solvent recovery step 
conducted offsite to onsite and as part of an existing process as a 
method of reducing consumption.
    (3) You may comply with the requirements of paragraph (a)(1) of this 
section for a series of processes, including situations where multiple 
processes are merged, if you demonstrate to the satisfaction of the 
Administrator that the multiple processes were merged after the baseline 
period into an existing process or processes.
    (b) Exclusions. (1) You must comply with the emission limitations 
and work practice standards contained in tables 1 through 7 of this 
subpart for all HAP that are generated in the MCPU and that are not 
included in consumption, as defined in Sec. 63.2550. If any vent stream 
routed to the combustion control is a halogenated vent stream, as 
defined in Sec. 63.2550, then hydrogen halides that are generated as a 
result of combustion control must be controlled according to the 
requirements of Sec. 63.994 and the requirements referenced therein.
    (2) You may not merge nondedicated formulation or nondedicated 
solvent recovery processes with any other processes.
    (c) Initial compliance procedures. To demonstrate initial compliance 
with paragraph (a) of this section, you must prepare a demonstration 
summary in accordance with paragraph (c) (1) of this section and 
calculate baseline and target annual HAP and VOC factors in accordance 
with paragraphs (c) (2) and (3) of this section.
    (1) Demonstration plan. You must prepare a pollution prevention 
demonstration plan that contains, at a minimum, the information in 
paragraphs (c)(1) (i) through (iii) of this section for each MCPU for 
which you comply with paragraph (a) of this section.
    (i) Descriptions of the methodologies and forms used to measure and 
record consumption of HAP and VOC compounds.
    (ii) Descriptions of the methodologies and forms used to measure and 
record production of the product(s).
    (iii) Supporting documentation for the descriptions provided in 
accordance with paragraphs (c)(1) (i) and (ii) of this section 
including, but not limited to, samples of operator log sheets and daily, 
monthly, and/or annual inventories of materials and products. You must 
describe how this documentation will be used to calculate the annual 
factors required in paragraph (d) of this section.
    (2) Baseline factors. You must calculate baseline HAP and VOC 
factors by dividing the consumption of total HAP and total VOC by the 
production rate, per process, for the first 3-year period in which the 
process was operational, beginning no earlier than the period consisting 
of the 1994 through 1996 calendar years.
    (3) Target annual factors. You must calculate target annual HAP and 
VOC factors. The target annual HAP factor must be equal to 35 percent of 
the baseline HAP factor. The target annual VOC factor must be lower than 
the

[[Page 345]]

baseline VOC factor by an amount equivalent to the reduction in any HAP 
that is also a VOC, on a mass basis. The target annual VOC factor may be 
the same as the baseline VOC factor if the only HAP you reduce is not a 
VOC.
    (d) Continuous compliance requirements. You must calculate annual 
rolling average values of the HAP and VOC factors (annual factors) in 
accordance with the procedures specified in paragraphs (d) (1) through 
(3) of this section. To show continuous compliance, the annual factors 
must be equal to or less than the target annual factors calculated 
according to paragraph (c)(3) of this section.
    (1) To calculate the annual factors, you must divide the consumption 
of both total HAP and total VOC by the production rate, per process, for 
12-month periods at the frequency specified in either paragraph (d) (2) 
or (3) of this section, as applicable.
    (2) For continuous processes, you must calculate the annual factors 
every 30 days for the 12-month period preceding the 30th day (i.e., 
annual rolling average calculated every 30 days). A process with both 
batch and continuous operations is considered a continuous process for 
the purposes of this section.
    (3) For batch processes, you must calculate the annual factors every 
10 batches for the 12-month period preceding the 10th batch (i.e., 
annual rolling average calculated every 10 batches), except as specified 
in paragraphs (d)(3) (i) and (ii) of this section.
    (i) If you produce more than 10 batches during a month, you must 
calculate the annual factors at least once during that month.
    (ii) If you produce less than 10 batches in a 12-month period, you 
must calculate the annual factors for the number of batches in the 12-
month period since the previous calculations.
    (e) Records. You must keep records of HAP and VOC consumption, 
production, and the rolling annual HAP and VOC factors for each MCPU for 
which you are complying with paragraph (a) of this section.
    (f) Reporting. (1) You must include the pollution prevention 
demonstration plan in the precompliance report required by Sec. 
63.2520(c).
    (2) You must identify all days when the annual factors were above 
the target factors in the compliance reports.

are controlled to less the percent reduction requirement.
    (1) Records of whether each batch operated was considered a standard 
batch.
    (2) The estimated uncontrolled and controlled emissions for each 
batch that is considered to be a nonstandard batch.
    (e) The information specified in paragraph (e)(2), (3), or (4) of 
this section, as applicable, for each process with Group 2 batch process 
vents or uncontrolled hydrogen halide and halogen HAP emissions from the 
sum of all batch and continuous process vents less than 1,000 lb/yr. No 
records are required for situations described in paragraph (e)(1) of 
this section.
    (1) No records are required if you documented in your notification 
of compliance status report that the MCPU meets any of the situations 
described in paragraph (e)(1)(i), (ii), or (iii) of this section.
    (i) The MCPU does not process, use, or generate HAP.
    (ii) You control the Group 2 batch process vents using a flare that 
meets the requirements of Sec. 63.987.

device for which your determination of worst case for initial compliance 
includes the contribution of all Group 2 batch process vents.
    (2) If you documented in your notification of compliance status 
report that an MCPU has Group 2 batch process vents because the non-
reactive organic HAP is the only HAP and usage is less than 10,000 lb/
yr, as specified in Sec. 63.2460(b)(7), you must keep records of the 
amount of HAP material used, and calculate the daily rolling annual sum 
of the amount used no less frequently than monthly. If a record 
indicates usage exceeds 10,000 lb/yr, you must estimate emissions for 
the preceding 12 months based on the number of batches operated and the 
estimated emissions for a standard batch, and you must begin 
recordkeeping as specified in paragraph (e)(4) of this section. After 1 
year, you may revert to recording only usage if the usage during the 
year is less than 10,000 lb.

process vents in an MCPU will be less than 1,000 lb/yr for the 
anticipated number of standard batches, then you must keep records of 
the number of batches operated and calculate a daily rolling annual sum 
of batches operated no less frequently than monthly. If the number of 
batches operated results in organic HAP emissions that exceed 1,000 lb/
yr, you must estimate emissions for the preceding 12 months based on the 
number of batches operated and the estimated emissions for a standard 
batch, and you must begin recordkeeping as specified in paragraph (e)(4) 
of this section. After 1 year, you may revert to recording only the 
number of batches if the number of batches operated during the year 
results in less than 1,000 lb of organic HAP emissions.
    (4) If you meet none of the conditions specified in paragraphs 
(e)(1) through (3) of this section, you must keep records of the 
information specified in paragraphs (e)(4)(i) through (iv) of this 
section.

standard batch.
    (iii) The estimated uncontrolled and controlled emissions for each 
batch that is considered to be a nonstandard batch.
    (iv) Records of the daily 365-day rolling summations of emissions, 
or alternative records that correlate to the emissions (e.g., number of 
batches), calculated no less frequently than monthly.
    (f) A record of each time a safety device is opened to avoid unsafe 
conditions in accordance with Sec. 63.2450(s).
    (g) Records of the results of each CPMS calibration check and the

initial PUG (i.e., identify the overlapping equipment between process 
units) required by Sec. 63.2535(l)(1)(v).
    (3) Calculations used to determine the primary product for the 
initial PUG required by Sec. 63.2535(l)(2)(iv).
    (4) Descriptions of process units added to the PUG after the 
creation date and rationale for including the additional process units 
in the PUG as required by Sec. 63.2535(l)(1)(v).
    (5) The calculation of each primary product redetermination required 
by Sec. 63.2535(l)(2)(iv).
    (j) In the SSMP required by Sec. 63.6(e)(3), you are not required

this subpart to all such equipment in the MCPU. If an MCPU subject to 
the provisions of this subpart has equipment to which this subpart does 
not apply but which is subject to a standard in 40 CFR part 60, subpart 
DDD, III, NNN, or RRR, you may elect to comply with the requirements for 
Group 1 process vents in this subpart for such equipment. If you elect 
any of these methods of compliance, you must consider all total organic 
compounds, minus methane and ethane, in such equipment for purposes of 
compliance with this subpart, as if they were organic HAP. Compliance 
with the provisions of this subpart, in the manner described in this 
paragraph (h), will constitute compliance with 40 CFR part 60, subpart 
DDD, III, NNN, or RRR, as applicable.
    (i) Compliance with 40 CFR part 61, subpart BB. (1) After the 
compliance dates specified in Sec. 63.2445, a Group 1 transfer rack, as 
defined in Sec. 63.2550, that is also subject to the provisions of 40 
CFR part 61, subpart BB, you are required to comply only with the 
provisions of this subpart.
    (2) After the compliance dates specified in Sec. 63.2445, a Group 2 
transfer rack, as defined in Sec. 63.2550, that is also subject to the 
provisions of 40 CFR part 61, subpart BB, is required to comply with the

BB, or the requirements for Group 1 transfer racks under this subpart 
FFFF.
    (ii) If the transfer rack is subject only to reporting and 
recordkeeping requirements under 40 CFR part 61, subpart BB, then you 
are required to comply only with the reporting and recordkeeping 
requirements specified in this subpart for Group 2 transfer racks, and 
you are exempt from the reporting and recordkeeping requirements in 40 
CFR part 61, subpart BB.
    (j) Compliance with 40 CFR part 61, subpart FF. After the compliance 
date specified in Sec. 63.2445, for a Group 1 or Group 2 wastewater 
stream that is also subject to the provisions of 40 CFR 61.342(c) 
through (h), and is not exempt under 40 CFR 61.342(c)(2) or (3), you may 
elect to comply only with the requirements for Group 1 wastewater 
streams in this subpart FFFF. If a Group 2 wastewater stream is exempted 
from 40 CFR 61.342(c)(1) under 40 CFR 61.342(c)(2) or (3), then you are 
required to comply only with the reporting and recordkeeping 
requirements specified in this subpart for Group 2 wastewater streams, 
and you are exempt from the requirements in 40 CFR part 61, subpart FF.

F, have the meaning given them in 40 CFR 65.2.
    (i) All other terms used in this subpart are defined in the Clean 
Air Act (CAA), in 40 CFR 63.2, and in this paragraph (i). If a term is 
defined in Sec. 63.2, Sec. 63.101, Sec. 63.111, Sec. 63.981, Sec. 
63.1020, Sec. 63.1061, Sec. 63.1251, or Sec. 65.2 and in this 
paragraph (i), the definition in this paragraph (i) applies for the 
purposes of this subpart.
    Ancillary activities means boilers and incinerators (not used to 
comply with the emission limits in Tables 1 through 7 to this subpart), 
chillers and refrigeration systems, and other equipment and activities 
that are not directly involved (i.e., they operate within a closed 
system and materials are not combined with process fluids) in the 
processing of raw materials or the manufacturing of a product or 
isolated intermediate.
    Batch operation means a noncontinuous operation involving 
intermittent or discontinuous feed into equipment, and, in general, 
involves the emptying of the equipment after the operation ceases and 
prior to beginning a new operation. Addition of raw material and 
withdrawal of product do not occur simultaneously in a batch operation.
    Batch process vent means a vent from a unit operation or vents from 
multiple unit operations within a process that are manifolded together 
into a common header, through which a HAP-containing gas stream is, or 
has the potential to be, released to the atmosphere. Examples of batch 
process vents include, but are not limited to, vents on condensers used 
for product recovery, reactors, filters, centrifuges, and process tanks. 
The following are not batch process vents for the purposes of this 
subpart:
    (1) Continuous process vents;
    (2) Bottoms receivers;
    (3) Surge control vessels;
    (4) Gaseous streams routed to a fuel gas system(s);
    (5) Vents on storage tanks, wastewater emission sources, or pieces 
of equipment subject to the emission limits and work practice standards 
in Tables 4, 6, and 7 to this subpart;
    (6) Drums, pails, and totes;
    (7) Flexible elephant trunk systems that draw ambient air (i.e., the 
system is not ducted, piped, or otherwise connected to the unit 
operations) away from operators when vessels are opened; and
    (8) Emission streams from emission episodes that are undiluted and 
uncontrolled containing less than 50 ppmv HAP are not part of any batch 
process vent. A vent from a unit operation, or a vent from multiple unit 
operations that are manifolded together, from which total uncontrolled 
HAP emissions are less than 200 lb/yr is not a batch process vent; 
emissions for all emission episodes associated with the unit 
operation(s) must be included in the determination of the total mass 
emitted. The HAP concentration or mass emission rate may be determined 
using any of the following: process knowledge that no HAP are present in 
the emission stream; an engineering assessment as discussed in Sec. 
63.1257(d)(2)(ii), except that you do not need to demonstrate that the 
equations in Sec. 63.1257(d)(2)(i) do not apply, and the precompliance 
reporting requirements specified in Sec. 63.1257(d)(2)(ii)(E) do not 
apply for the purposes of this demonstration; equations specified in 
Sec. 63.1257(d)(2)(i), as applicable; test data using Method 18 of 40 
CFR part 60, appendix A; or any other test method that has been 
validated according to the procedures in Method 301 of appendix A of 
this part.
    Biofilter means an enclosed control system such as a tank or series 
of tanks with a fixed roof that contact emissions with a solid media 
(such as bark) and use microbiological activity to transform organic 
pollutants in a process vent stream to innocuous compounds such as 
carbon dioxide, water, and inorganic salts. Wastewater treatment 
processes such as aeration lagoons or activated sludge systems are not 
considered to be biofilters.
    Bottoms receiver means a tank that collects bottoms from continuous 
distillation before the stream is sent for storage or for further 
downstream processing.
    Construction means the onsite fabrication, erection, or installation 
of an affected source or MCPU. Addition of new equipment to an MCPU 
subject to

[[Page 358]]

existing source standards does not constitute construction, but it may 
constitute reconstruction of the affected source or MCPU if it satisfies 
the definition of reconstruction in Sec. 63.2.
    Consumption means the quantity of all HAP raw materials entering a 
process in excess of the theoretical amount used as reactant, assuming 
100 percent stoichiometric conversion. The raw materials include 
reactants, solvents, and any other additives. If a HAP is generated in 
the process as well as added as a raw material, consumption includes the 
quantity generated in the process.
    Continuous operation means any operation that is not a batch 
operation.
    Continuous process vent means the point of discharge to the 
atmosphere (or the point of entry into a control device, if any) of a 
gas stream if the gas stream has the characteristics specified in Sec. 
63.107(b) through (h), or meets the criteria specified in Sec. 
63.107(i), except:
    (1) The reference in Sec. 63.107(e) to a chemical manufacturing 
process unit that meets the criteria of Sec. 63.100(b) means an MCPU 
that meets the criteria of Sec. 63.2435(b);
    (2) The reference in Sec. 63.107(h)(4) to Sec. 63.113 means Table 
1 to this subpart;
    (3) The references in Sec. 63.107(h)(7) to Sec. Sec. 63.119 and 
63.126 mean tables 4 and 5 to this subpart; and
    (4) For the purposes of Sec. 63.2455, all references to the 
characteristics of a process vent (e.g., flowrate, total HAP 
concentration, or TRE index value) mean the characteristics of the gas 
stream.
    (5) The reference to ``total organic HAP'' in Sec. 63.107(d) means 
``total HAP'' for the purposes of this subpart FFFF.
    (6) The references to an ``air oxidation reactor, distillation unit, 
or reactor'' in Sec. 63.107 mean any continuous operation for the 
purposes of this subpart.
    (7) A separate determination is required for the emissions from each 
MCPU, even if emission streams from two or more MCPU are combined prior 
to discharge to the atmosphere or to a control device.
    Dedicated MCPU means an MCPU that consists of equipment that is used 
exclusively for one process, except that storage tanks assigned to the 
process according to the procedures in Sec. 63.2435(d) also may be 
shared by other processes.
    Deviation means any instance in which an affected source subject to 
this subpart, or an owner or operator of such a source:
    (1) Fails to meet any requirement or obligation established by this 
subpart including, but not limited to, any emission limit, operating 
limit, or work practice standard; or
    (2) Fails to meet any term or condition that is adopted to implement 
an applicable requirement in this subpart and that is included in the 
operating permit for any affected source required to obtain such a 
permit; or
    (3) Fails to meet any emission limit, operating limit, or work 
practice standard in this subpart during startup, shutdown, or 
malfunction, regardless of whether or not such failure is permitted by 
this subpart.
    Emission point means each continuous process vent, batch process 
vent, storage tank, transfer rack, and wastewater stream.
    Energetics means propellants, explosives, and pyrotechnics and 
include materials listed at 49 CFR 172.101 as Hazard Class I Hazardous 
Materials, Divisions 1.1 through 1.6.
    Equipment means each pump, compressor, agitator, pressure relief 
device, sampling connection system, open-ended valve or line, valve, 
connector, and instrumentation system in organic HAP service; and any 
control devices or systems used to comply with Table 6 to this subpart.
    Excess emissions means emissions greater than those allowed by the 
emission limit.
    Family of materials means a grouping of materials with the same 
basic composition or the same basic end use or functionality produced 
using the same basic feedstocks with essentially identical HAP emission 
profiles (primary constituent and relative magnitude on a pound per 
product basis) and manufacturing equipment configuration. Examples of 
families of materials include multiple grades of the same product or 
different variations of a product (e.g., blue, black, and red resins).

[[Page 359]]

    Group 1 batch process vent means each of the batch process vents in 
a process for which the collective uncontrolled organic HAP emissions 
from all of the batch process vents are greater than or equal to 10,000 
lb/yr at an existing source or greater than or equal to 3,000 lb/yr at a 
new source.
    Group 2 batch process vent means each batch process vent that does 
not meet the definition of Group 1 batch process vent.
    Group 1 continuous process vent means a continuous process vent for 
which the flow rate is greater than or equal to 0.005 standard cubic 
meter per minute, and the total resource effectiveness index value, 
calculated according to Sec. 63.2455(b), is less than or equal to 1.9 
at an existing source and less than or equal to 5.0 at a new source.
    Group 2 continuous process vent means a continuous process vent that 
does not meet the definition of a Group 1 continuous process vent.

than or equal to 10,000 gal storing material that has a maximum true 
vapor pressure of total HAP greater than or equal to 6.9 kilopascals at 
an existing source or greater than or equal to 0.69 kilopascals at a new 
source.
    Group 2 storage tank means a storage tank that does not meet the 
definition of a Group 1 storage tank.
    Group 1 transfer rack means a transfer rack that loads more than 
0.65 million liters/year of liquids that contain organic HAP with a

greater than or equal to 1.5 pound per square inch absolute.
    Group 2 transfer rack means a transfer rack that does not meet the 
definition of a Group 1 transfer rack.
    Group 1 wastewater stream means a wastewater stream consisting of 
process wastewater at an existing or new source that meets the criteria 
for Group 1 status in Sec. 63.2485(c) for compounds in Tables 8 and 9 
to this subpart and/or a wastewater stream consisting of process 
wastewater at a new source that meets the criteria for Group 1 status in 
Sec. 63.132(d) for compounds in Table 8 to subpart G of this part 63.
    Group 2 wastewater stream means any process wastewater stream that 
does not meet the definition of a Group 1 wastewater stream.

mass emission rate of halogen atoms contained in organic compounds of 
0.45 kilograms per hour or greater determined by the procedures 
presented in Sec. 63.115(d)(2)(v).
    HAP metals means the metal portion of antimony compounds, arsenic 
compounds, beryllium compounds, cadmium compounds, chromium compounds, 
cobalt compounds, lead compounds, manganese compounds, mercury 
compounds, nickel compounds, and selenium compounds.
    Hydrogen halide and halogen HAP means hydrogen chloride, hydrogen 
fluoride, and chlorine.
    In organic HAP service means that a piece of equipment either 
contains or contacts a fluid (liquid or gas) that is at least 5 percent 
by weight of total organic HAP as determined according to the provisions 
of Sec. 63.180(d). The provisions of Sec. 63.180(d) also specify how 
to determine that a piece of equipment is not in organic HAP service.
    Isolated intermediate means a product of a process that is stored 
before subsequent processing. An isolated intermediate is usually a 
product of a chemical synthesis, fermentation, or biological extraction 
process. Storage of an isolated intermediate marks the end of a process. 
Storage occurs at any time the intermediate is placed in equipment used 
solely for storage. The storage equipment is part of the MCPU that 
produces the isolated intermediate and is not assigned as specified in 
Sec. 63.2435(d).
    Large control device means a control device that controls total HAP 
emissions of greater than or equal to 10 tpy, before control.
    Maintenance wastewater means wastewater generated by the draining of 
process fluid from components in the MCPU into an individual drain 
system in preparation for or during maintenance activities. Maintenance 
wastewater can be generated during planned and unplanned shutdowns and 
during

[[Page 360]]

periods not associated with a shutdown. Examples of activities that can 
generate maintenance wastewater include descaling of heat exchanger 
tubing bundles, cleaning of distillation column traps, draining of pumps 
into an individual drain system, and draining of portions of the MCPU 
for repair. Wastewater from routine cleaning operations occurring as 
part of batch operations is not considered maintenance wastewater.
    Maximum true vapor pressure has the meaning given in Sec. 63.111, 
except that it applies to all HAP rather than only organic HAP.
    Miscellaneous organic chemical manufacturing process means all 
equipment which collectively function to produce a product or isolated 
intermediate that are materials described in Sec. 63.2435(b). For the 
purposes of this subpart, process includes any, all or a combination of 
reaction, recovery, separation, purification, or other activity, 
operation, manufacture, or treatment which are used to produce a product 
or isolated intermediate. A process is also defined by the following:
    (1) Routine cleaning operations conducted as part of batch 
operations are considered part of the process;
    (2) Each nondedicated solvent recovery operation is considered a 
single process;
    (3) Each nondedicated formulation operation is considered a single 
process that is used to formulate numerous materials and/or products;
    (4) Quality assurance/quality control laboratories are not 
considered part of any process; and
    (5) Ancillary activities are not considered a process or part of any 
process.
    (6) The end of a process that produces a solid material is either up 
to and including the dryer or extruder, or for a polymer production 
process without a dryer or extruder, it is up to and including the 
extruder, die plate, or solid-state reactor, except in two cases. If the 
dryer, extruder, die plate, or solid-state reactor is followed by an 
operation that is designed and operated to remove HAP solvent or 
residual HAP monomer from the solid, then the solvent removal operation 
is the last step in the process. If the dried solid is diluted or mixed 
with a HAP-based solvent, then the solvent removal operation is the last 
step in the process.
    Nondedicated solvent recovery operation means a distillation unit or 
other purification equipment that receives used solvent from more than 
one MCPU.
    Nonstandard batch means a batch process that is operated outside of 
the range of operating conditions that are documented in an existing 
operating scenario but is still a reasonably anticipated event. For 
example, a nonstandard batch occurs when additional processing or 
processing at different operating conditions must be conducted to 
produce a product that is normally produced under the conditions 
described by the standard batch. A nonstandard batch may be necessary as 
a result of a malfunction, but it is not itself a malfunction.
    On-site or on site means, with respect to records required to be 
maintained by this subpart or required by another subpart referenced by 
this subpart, that records are stored at a location within a major 
source which encompasses the affected source. On-site includes, but is 
not limited to, storage at the affected source or MCPU to which the 
records pertain, or storage in central files elsewhere at the major 
source.
    Operating scenario means, for the purposes of reporting and 
recordkeeping, any specific operation of an MCPU as described by records 
specified in Sec. 63.2525(b).
    Organic group means structures that contain primarily carbon, 
hydrogen, and oxygen atoms.
    Organic peroxides means organic compounds containing the bivalent -
o-o-structure which may be considered to be a structural derivative of 
hydrogen peroxide where one or both of the hydrogen atoms has been 
replaced by an organic radical.
    Point of determination means each point where process wastewater 
exits the MCPU or control device.

    Note to definition for point of determination: The regulation allows 
determination of the characteristics of a wastewater stream: At the 
point of determination; or downstream of the point of determination if 
corrections are made for changes in flow rate and annual average 
concentration of soluble HAP and partially soluble HAP compounds

[[Page 361]]

as determined according to procedures in Sec. 63.144 of subpart G in 
this part 63. Such changes include losses by air emissions; reduction of 
annual average concentration or changes in flow rate by mixing with 
other water or wastewater streams; and reduction in flow rate or annual 
average concentration by treating or otherwise handling the wastewater 
stream to remove or destroy HAP.

    Predominant HAP means as used in calibrating an analyzer, the single 
organic HAP that constitutes the largest percentage of the total organic 
HAP in the analyzed gas stream, by volume.
    Process condenser means a condenser whose primary purpose is to 
recover material as an integral part of an MCPU. All condensers 
recovering condensate from an MCPU at or above the boiling point or all 
condensers in line prior to a vacuum source are considered process 
condensers. Typically, a primary condenser or condensers in series are 
considered to be integral to the MCPU if they are capable of and 
normally used for the purpose of recovering chemicals for fuel value 
(i.e., net positive heating value), use, reuse or for sale for fuel 
value, use, or reuse. This definition does not apply to a condenser that 
is used to remove materials that would hinder performance of a 
downstream recovery device as follows:
    (1) To remove water vapor that would cause icing in a downstream 
condenser, or
    (2) To remove water vapor that would negatively affect the 
adsorption capacity of carbon in a downstream carbon adsorber, or
    (3) To remove high molecular weight organic compounds or other 
organic compounds that would be difficult to remove during regeneration 
of a downstream carbon adsorber.
    Process tank means a tank or vessel that is used within a process to 
collect material discharged from a feedstock storage tank or equipment 
within the process before the material is transferred to other equipment 
within the process or a product storage tank. A process tank has 
emissions that are related to the characteristics of the batch cycle, 
and it does not accumulate product over multiple batches. Surge control 
vessels and bottoms receivers are not process tanks.
    Production-indexed HAP consumption factor (HAP factor) means the 
result of dividing the annual consumption of total HAP by the annual 
production rate, per process.
    Production-indexed VOC consumption factor (VOC factor) means the 
result of dividing the annual consumption of total VOC by the annual 
production rate, per process.
    Quaternary ammonium compounds means a type of organic nitrogen 
compound in which the molecular structure includes a central nitrogen 
atom joined to four organic groups as well as an acid radical of some 
sort.
    Recovery device means an individual unit of equipment used for the 
purpose of recovering chemicals from process vent streams and from 
wastewater streams for fuel value (i.e., net positive heating value), 
use, reuse, or for sale for fuel value, use, or reuse. For the purposes 
of meeting requirements in table 2 to this subpart, the recovery device 
must not be a process condenser and must recover chemicals to be reused 
in a process on site. Examples of equipment that may be recovery devices 
include absorbers, carbon adsorbers, condensers, oil-water separators or 
organic-water separators, or organic removal devices such as decanters, 
strippers, or thin-film evaporation units. To be a recovery device for a 
wastewater stream, a decanter and any other equipment based on the 
operating principle of gravity separation must receive only multi-phase 
liquid streams.
    Responsible official means responsible official as defined in 40 CFR 
70.2.
    Safety device means a closure device such as a pressure relief 
valve, frangible disc, fusible plug, or any other type of device which 
functions exclusively to prevent physical damage or permanent 
deformation to a unit or its air emission control equipment by venting 
gases or vapors directly to the atmosphere during unsafe conditions 
resulting from an unplanned, accidental, or emergency event. For the 
purposes of this subpart, a safety device is not used for routine 
venting of gases or vapors from the vapor headspace underneath a cover 
such as during filling of the unit or to adjust the pressure in response 
to normal daily diurnal ambient temperature

[[Page 362]]

fluctuations. A safety device is designed to remain in a closed position 
during normal operations and open only when the internal pressure, or 
another relevant parameter, exceeds the device threshold setting 
applicable to the air emission control equipment as determined by the 
owner or operator based on manufacturer recommendations, applicable 
regulations, fire protection and prevention codes and practices, or 
other requirements for the safe handling of flammable, combustible, 
explosive, reactive, or hazardous materials.
    Shutdown means the cessation of operation of a continuous operation 
for any purpose. Shutdown also means the cessation of a batch operation, 
or any related individual piece of equipment required or used to comply 
with this subpart, if the steps taken to cease operation differ from 
those described in a standard batch or nonstandard batch. Shutdown also 
applies to emptying and degassing storage vessels. Shutdown does not 
apply to cessation of batch operations at the end of a campaign or 
between batches within a campaign when the steps taken are routine 
operations.
    Small control device means a control device that controls total HAP 
emissions of less than 10 tpy, before control.
    Standard batch means a batch process operated within a range of 
operating conditions that are documented in an operating scenario. 
Emissions from a standard batch are based on the operating conditions 
that result in highest emissions. The standard batch defines the 
uncontrolled and controlled emissions for each emission episode defined 
under the operating scenario.
    Startup means the setting in operation of a continuous operation for 
any purpose; the first time a new or reconstructed batch operation 
begins production; for new equipment added, including equipment required 
or used to comply with this subpart, the first time the equipment is put 
into operation; or for the introduction of a new product/process, the 
first time the product or process is run in equipment. For batch 
operations, startup applies to the first time the equipment is put into 
operation at the start of a campaign to produce a product that has been 
produced in the past if the steps taken to begin production differ from 
those specified in a standard batch or nonstandard batch. Startup does 
not apply when the equipment is put into operation as part of a batch 
within a campaign when the steps taken are routine operations.
    Storage tank means a tank or other vessel that is used to store 
liquids that contain organic HAP and/or hydrogen halide and halogen HAP 
and that has been assigned to an MCPU according to the procedures in 
Sec. 63.2435(d). The following are not considered storage tanks for the 
purposes of this subpart:
    (1) Vessels permanently attached to motor vehicles such as trucks, 
railcars, barges, or ships;
    (2) Pressure vessels designed to operate in excess of 204.9 
kilopascals and without emissions to the atmosphere;
    (3) Vessels storing organic liquids that contain HAP only as 
impurities;
    (4) Wastewater storage tanks;
    (5) Bottoms receivers;
    (6) Surge control vessels; and
    (7) Process tanks.
    Supplemental gases means the air that is added to a vent stream 
after the vent stream leaves the unit operation. Air that is part of the 
vent stream as a result of the nature of the unit operation is not 
considered supplemental gases. Air required to operate combustion device 
burner(s) is not considered supplemental gases.
    Surge control vessel means feed drums, recycle drums, and 
intermediate vessels as part of any continuous operation. Surge control 
vessels are used within an MCPU when in-process storage, mixing, or 
management of flowrates or volumes is needed to introduce material into 
continuous operations.
    Total organic compounds or (TOC) means the total gaseous organic 
compounds (minus methane and ethane) in a vent stream.
    Transfer rack means the collection of loading arms and loading 
hoses, at a single loading rack, that are assigned to an MCPU according 
to the procedures specified in Sec. 63.2435(d) and are used to fill 
tank trucks and/or rail cars with organic liquids that contain one or 
more of the organic HAP listed in

[[Page 363]]

section 112(b) of the CAA of this subpart. Transfer rack includes the 
associated pumps, meters, shutoff valves, relief valves, and other 
piping and valves.
    Unit operation means those processing steps that occur within 
distinct equipment that are used, among other things, to prepare 
reactants, facilitate reactions, separate and purify products, and 
recycle materials. Equipment used for these purposes includes, but is 
not limited to, reactors, distillation columns, extraction columns, 
absorbers, decanters, dryers, condensers, and filtration equipment.
    Waste management unit means the equipment, structure(s), and/or 
device(s) used to convey, store, treat, or dispose of wastewater streams 
or residuals. Examples of waste management units include wastewater 
tanks, air flotation units, surface impoundments, containers, oil-water 
or organic-water separators, individual drain systems, biological 
wastewater treatment units, waste incinerators, and organic removal 
devices such as steam and air stripper units, and thin film evaporation 
units. If such equipment is being operated as a recovery device, then it 
is part of a miscellaneous organic chemical manufacturing process and is 
not a waste management unit.
    Wastewater means water that is discarded from an MCPU or control 
device through a POD and that contains either: an annual average 
concentration of compounds in tables 8 and 9 to this subpart of at least 
5 ppmw and has an annual average flowrate of 0.02 liters per minute or 
greater; or an annual average concentration of compounds in tables 8 and 
9 to this subpart of at least 10,000 ppmw at any flowrate. Wastewater 
means process wastewater or maintenance wastewater. The following are 
not considered wastewater for the purposes of this subpart:
    (1) Stormwater from segregated sewers;
    (2) Water from fire-fighting and deluge systems, including testing 
of such systems;
    (3) Spills;
    (4) Water from safety showers;
    (5) Samples of a size not greater than reasonably necessary for the 
method of analysis that is used;

 Subpart GGGG_National Emission Standards for Hazardous Air Pollutants: 
             Solvent Extraction for Vegetable Oil Production

    Source: 66 FR 19011, Apr. 12, 2001, unless otherwise noted.

                        What This Subpart Covers



Sec. 63.2830  What is the purpose of this subpart?

    This subpart establishes national emission standards for hazardous 
air pollutants (NESHAP) for emissions during vegetable oil production. 
This subpart limits hazardous air pollutant (HAP) emissions from 
specified vegetable oil production processes. This subpart also 
establishes requirements to demonstrate initial and continuous 
compliance with the emission standards.



Sec. 63.2831  Where can I find definitions of key words used in this subpart?

    You can find definitions of key words used in this subpart in Sec. 
63.2872.



Sec. 63.2832  Am I subject to this subpart?

    (a) You are an affected source subject to this subpart if you meet 
all of the criteria listed in paragraphs (a)(1) and (2) of this section:
    (1) You own or operate a vegetable oil production process that is a 
major source of HAP emissions or is collocated within a plant site with 
other sources that are individually or collectively a major source of 
HAP emissions.
    (i) A vegetable oil production process is defined in Sec. 63.2872. 
In general, it is the collection of continuous process equipment and 
activities that produce crude vegetable oil and meal products by 
removing oil from oilseeds listed in Table 1 to Sec. 63.2840 through 
direct contact with an organic solvent, such as a hexane isomer blend.
    (ii) A major source of HAP emissions is a plant site that emits or 
has the potential to emit any single HAP at a rate of 10 tons (9.07 
megagrams) or more per year or any combination of HAP at a rate of 25 
tons (22.68 megagrams) or more per year.
    (2) Your vegetable oil production process processes any combination 
of eight types of oilseeds listed in paragraphs (a)(2)(i) through (viii) 
of this section:
    (i) Corn germ;
    (ii) Cottonseed;
    (iii) Flax;
    (iv) Peanut;
    (v) Rapeseed (for example, canola);
    (vi) Safflower;
    (vii) Soybean; and
    (viii) Sunflower.
    (b) You are not subject to this subpart if your vegetable oil 
production process meets any of the criteria listed in paragraphs (b)(1) 
through (4) of this section:
    (1) It uses only mechanical extraction techniques that use no 
organic solvent to remove oil from a listed oilseed.
    (2) It uses only batch solvent extraction and batch desolventizing 
equipment.
    (3) It processes only agricultural products that are not listed 
oilseeds as defined in Sec. 63.2872.
    (4) It functions only as a research and development facility and is 
not a major source.
    (c) As listed in Sec. 63.1(c)(5) of the General Provisions, if your 
HAP emissions increase such that you become a major source, then you are 
subject to all of the requirements of this subpart.



Sec. 63.2833  Is my source categorized as existing or new?

    (a) This subpart applies to each existing and new affected source. 
You must categorize your vegetable oil production process as either an 
existing or a new source in accordance with the criteria in Table 1 of 
this section, as follows:

 Table 1 to Sec. 63.2833--Categorizing Your Source as Existing or New

(6) began construction on or      ..................  is a new source.
 after May 26, 2000.
------------------------------------------------------------------------

    (b) Reconstruction of a source. Any affected source is reconstructed 
if components are replaced so that the criteria in the definition of 
reconstruction in Sec. 63.2 are satisfied. In general, a vegetable oil 
production process is reconstructed if the fixed capital cost of the new 
components exceeds 50 percent of the fixed capital cost for constructing 
a new vegetable oil production process, and it is technically and 
economically feasible for the reconstructed source to meet the relevant 
new source requirements of this subpart. The effect of reconstruction on 
the categorization of your existing and new affected source is described 
in paragraphs (b)(1) and (2) of this section:
    (1) After reconstruction of an existing source, the affected source 
is recategorized as a new source and becomes subject to the new source 
requirements of this subpart.
    (2) After reconstruction of a new source, the affected source 
remains categorized as a new source and remains subject to the new 
source requirements of this subpart.
    (c) Significant modification of a source. A significant modification 
to an affected source is a term specific to this subpart and is defined 
in Sec. 63.2872.
    (1) In general, a significant modification to your source consists 
of adding new equipment or the modification of existing equipment within 
the affected source that significantly affects solvent losses from the 
affected source. Examples include adding or replacing extractors, 
desolventizer-toasters (conventional and specialty), and meal dryer-
coolers. All other significant modifications must meet the criteria 
listed in paragraphs (c)(1)(i) and (ii) of this section:
    (i) The fixed capital cost of the modification represents a 
significant percentage of the fixed capital cost of building a 
comparable new vegetable oil production process.
    (ii) It does not constitute reconstruction as defined in Sec. 63.2.
    (2) A significant modification has no effect on the categorization 
of your source as existing and new. An existing source remains 
categorized as an existing source and subject to the existing source 
requirements of this subpart. A new source remains categorized as a new 
source and subject to the new source requirements of this subpart.
    (d) Changes in the type of oilseed processed by your affected source 
does not affect the categorization of your source as new or existing. 
Recategorizing an affected source from existing to new occurs only when 
you add or modify process equipment within the source which meets the 
definition of reconstruction.

                                Standards



Sec. 63.2840  What emission requirements must I meet?

    For each facility meeting the applicability criteria in Sec. 
63.2832, you must comply with either the requirements specified in 
paragraphs (a) through (d), or the requirements in paragraph (e) of this 
section.
    (a)(1) The emission requirements limit the number of gallons of HAP 
lost per ton of listed oilseeds processed. For each operating month, you 
must calculate a compliance ratio which compares your actual HAP loss to 
your allowable HAP loss for the previous 12 operating months as shown in 
Equation 1 of this section. An operating month, as defined in Sec. 
63.2872, is any calendar month in which a source processes a listed 
oilseed, excluding any entire calendar month in which the source 
operated under an initial startup period subject to Sec. 63.2850(c)(2) 
or (d)(2) or a malfunction period subject to Sec. 63.2850(e)(2). 
Equation 1 of this section follows:
[GRAPHIC] [TIFF OMITTED] TR12AP01.001

    (2) Equation 1 of this section can also be expressed as a function 
of total solvent loss as shown in Equation 2 of this section. Equation 2 
of this section follows:
[GRAPHIC] [TIFF OMITTED] TR12AP01.002

Where:

f = The weighted average volume fraction of HAP in solvent received 
          during the previous 12 operating months, as determined in 
          Sec. 63.2854, dimensionless.
0.64 = The average volume fraction of HAP in solvent in the baseline 
          performance data, dimensionless.
Actual Solvent Loss = Gallons of actual solvent loss during previous 12 
          operating months, as determined in Sec. 63.2853.

    (b) When your source has processed listed oilseed for 12 operating 
months, calculate the compliance ratio by the end of each calendar month 
following an operating month using Equation 2 of this section. When 
calculating your compliance ratio, consider the conditions and 
exclusions in paragraphs (b)(1) through (6) of this section:
    (1) If your source processes any quantity of listed oilseeds in a 
calendar month and the source is not operating under an initial startup 
period or malfunction period subject to Sec. 63.2850, then you must 
categorize the month as an operating month, as defined in Sec. 63.2872.
    (2) The 12-month compliance ratio may include operating months 
occurring prior to a source shutdown and operating months that follow 
after the source resumes operation.
    (3) If your source shuts down and processes no listed oilseed for an 
entire calendar month, then you must categorize the month as a 
nonoperating month, as defined in Sec. 63.2872. Exclude any 
nonoperating months from the compliance ratio determination.
    (4) If your source is subject to an initial startup period as 
defined in Sec. 63.2872, exclude from the compliance ratio 
determination any solvent and oilseed information recorded for the 
initial startup period.
    (5) If your source is subject to a malfunction period as defined in 
Sec. 63.2872, exclude from the compliance ratio determination any 
solvent and oilseed information recorded for the malfunction period.
    (6) For sources processing cottonseed or specialty soybean, the 
solvent loss

[[Page 375]]

factor you use to determine the compliance ratio may change each 
operating month depending on the tons of oilseed processed during all 
normal operating periods in a 12 operating month period.
    (c) If the compliance ratio is less than or equal to 1.00, your 
source was in compliance with the HAP emission requirements for the 
previous operating month.
    (d) To determine the compliance ratio in Equation 2 of this section, 
you must select the appropriate oilseed solvent loss factor from Table 1 
of this section. First, determine whether your source is new or existing 
using Table 1 of Sec. 63.2833. Then, under the appropriate existing or 
new source column, select the oilseed solvent loss factor that 
corresponds to each type oilseed or process operation for each operating 
month.
    (e) Low-HAP solvent option. For all vegetable oil production 
processes subject to this subpart, you must exclusively use solvent 
where the volume fraction of each HAP comprises 1 percent or less by 
volume of the solvent (low-HAP solvent) in each delivery, and you must 
meet the requirements in paragraphs (e)(1) through (5) of this section. 
Your vegetable oil production process is not subject to the requirements 
in Sec. Sec. 63.2850 through 63.2870 unless specifically referenced in 
paragraphs (e)(1) through (5) of this section.
    (1) You shall determine the HAP content of your solvent in 
accordance with the specifications in Sec. 63.2854(b)(1).
    (2) You shall maintain documentation of the HAP content 
determination for each delivery of the solvent at the facility at all 
times.
    (3) You must submit an initial notification for existing sources in 
accordance with Sec. 63.2860(a).
    (4) You must submit an initial notification for new and 
reconstructed sources in accordance with Sec. 63.2860(b).
    (5) You must submit an annual compliance certification in accordance 
with Sec. 63.2861(a). The certification should only include the 
information required under Sec. 63.2861(a)(1) and (2), and a 
certification indicating whether the source complied with all of the 
requirements in paragraph (e) of this section.
    (f) You may change compliance options for your source if you submit 
a notice to the Administrator at least 60 days prior to changing 
compliance options. If your source changes from the low-HAP solvent 
option to the compliance ratio determination option, you must determine 
the compliance ratio for the most recent 12 operating months beginning 
with the first month after changing compliance options.

standards?

    (a) General requirements. The requirements in paragraphs (a)(1)(i) 
through (iv) of this section apply to all affected sources:
    (1) Submit the necessary notifications in accordance with Sec. 
63.2860, which include:
    (i) Initial notifications for existing sources.
    (ii) Initial notifications for new and reconstructed sources.
    (iii) Initial notifications for significant modifications to 
existing or new sources.
    (iv) Notification of compliance status.
    (2) Develop and implement a plan for demonstrating compliance in 
accordance with Sec. 63.2851.
    (3) Develop a written startup, shutdown and malfunction (SSM) plan 
in accordance with the provisions in Sec. 63.2852.
    (4) Maintain all the necessary records you have used to demonstrate 
compliance with this subpart in accordance with Sec. 63.2862.
    (5) Submit the reports in paragraphs (a)(5)(i) through (iii) of this 
section:
    (i) Annual compliance certifications in accordance with Sec. 
63.2861(a).
    (ii) Periodic SSM reports in accordance with Sec. 63.2861(c).
    (iii) Immediate SSM reports in accordance with Sec. 63.2861(d).
    (6) Submit all notifications and reports and maintain all records 
required by the General Provisions for performance testing if you add a 
control device that destroys solvent.

[[Page 376]]

    (b) Existing sources under normal operation. You must meet all of 
the requirements listed in paragraph (a) of this section and table 1 of 
this section for sources under normal operation, and the schedules for 
demonstrating compliance for existing sources under normal operation in 
table 2 of this section.
    (c) New sources. Your new source, including a source that is 
categorized as new due to reconstruction, must meet the requirements 
associated with one of two compliance options. Within 15 days of the 
startup date, you must choose to comply with one of the options listed 
in paragraph (c)(1) or (2) of this section:
    (1) Normal operation. Upon startup of your new source, you must meet 
all of the requirements listed in Sec. 63.2850(a) and table 1 of this 
section for sources under normal operation, and the schedules for 
demonstrating compliance for new sources under normal operation in table 
2 of this section.
    (2) Initial startup period. For up to 6 calendar months after the 
startup date of your new source, you must meet all of the requirements 
listed in paragraph (a) of this section and table 1 of this section for 
sources operating under an initial startup period, and the schedules for 
demonstrating compliance for new sources operating under an initial 
startup period in Table 2 of this section. After a maximum of 6 calendar 
months, your new source must then meet all of the requirements listed in 
table 1 of this section for sources under normal operation.
    (d) Existing or new sources that have been significantly modified. 
Your existing or new source that has been significantly modified must 
meet the requirements associated with one of two compliance options. 
Within 15 days of the modified source startup date, you must choose to 
comply with one of the options listed in paragraph (d)(1) or (2) of this 
section:
    (1) Normal operation. Upon startup of your significantly modified 
existing or new source, you must meet all of the requirements listed in 
paragraph (a) of this section and table 1 of this section for sources 
under normal operation, and the schedules for demonstrating compliance 
for an existing or new source that has been significantly modified in 
table 2 of this section.
    (2) Initial startup period. For up to 3 calendar months after the 
startup date of your significantly modified existing or new source, you 
must meet all of the requirements listed in paragraph (a) of this 
section and table 1 of this section for sources operating under an 
initial startup period, and the schedules for demonstrating compliance 
for a significantly modified existing or new source operating under an 
initial startup period in table 2 of this section. After a maximum of 3 
calendar months, your new or existing source must meet all of the 
requirements listed in Table 1 of this section for sources under normal 
operation.
    (e) Existing or new sources experiencing a malfunction. A 
malfunction is defined in Sec. 63.2. In general, it means any sudden, 
infrequent, and not reasonably preventable failure of air pollution 
control equipment or process equipment to function in a usual manner. If 
your existing or new source experiences an unscheduled shutdown as a 
result of a malfunction, continues to operate during a malfunction 
(including the period reasonably necessary to correct the malfunction), 
or starts up after a shutdown resulting from a malfunction, then you 
must meet the requirements associated with one of two compliance 
options. Routine or scheduled process startups and shutdowns resulting 
from, but not limited to, market demands, maintenance activities, and 
switching types of oilseed processed, are not startups or shutdowns 
resulting from a malfunction and, therefore, do not qualify for this 
provision. Within 15 days of the beginning date of the malfunction, you 
must choose to comply with one of the options listed in paragraphs 
(e)(1) through (2) of this section:
    (1) Normal operation. Your source must meet all of the requirements 
listed in paragraph (a) of this section and one of the options listed in 
paragraphs (e)(1)(i) through (iii) of this section:
    (i) Existing source normal operation requirements in paragraph (b) 
of this section.
    (ii) New source normal operation requirements in paragraph (c)(1) of 
this section.

[[Page 377]]

    (iii) Normal operation requirements for sources that have been 
significantly modified in paragraph (d)(1) of this section.
    (2) Malfunction period. Throughout the malfunction period, you must 
meet all of the requirements listed in paragraph (a) of this section and 
Table 1 of this section for sources operating during a malfunction 
period. At the end of the malfunction period, your source must then meet 
all of the requirements listed in table 1 of this section for sources 
under normal operation. Table 1 of this section follows:

Sec. 63.2851  What is a plan for demonstrating compliance?

    (a) You must develop and implement a written plan for demonstrating 
compliance that provides the detailed procedures you will follow to 
monitor and record data necessary for demonstrating compliance with this 
subpart. Procedures followed for quantifying solvent loss from the 
source and amount of oilseed processed vary from source to source 
because of site-specific factors such as equipment design 
characteristics and operating conditions. Typical procedures include one 
or more accurate measurement methods such as weigh scales, volumetric 
displacement, and material mass balances. Because the industry does not 
have a uniform set of procedures, you must develop and implement your 
own site-specific plan for demonstrating compliance before the 
compliance date for your source. You must also incorporate the plan for 
demonstrating compliance by reference in the source's title V permit and 
keep the plan on-site and readily available as long as the source is 
operational. If you make any changes to the plan for demonstrating 
compliance, then you must keep all previous versions of the plan and 
make them readily available for inspection

[[Page 379]]

for at least 5 years after each revision. The plan for demonstrating 
compliance must include the items in paragraphs (a)(1) through (7) of 
this section:
    (1) The name and address of the owner or operator.
    (2) The physical address of the vegetable oil production process.
    (3) A detailed description of all methods of measurement your source 
will use to determine your solvent losses, HAP content of solvent, and 
the tons of each type of oilseed processed.
    (4) When each measurement will be made.
    (5) Examples of each calculation you will use to determine your 
compliance status. Include examples of how you will convert data 
measured with one parameter to other terms for use in compliance 
determination.
    (6) Example logs of how data will be recorded.
    (7) A plan to ensure that the data continue to meet compliance 
demonstration needs.
    (b) The responsible agency of these NESHAP may require you to revise 
your plan for demonstrating compliance. The responsible agency may 
require reasonable revisions if the procedures lack detail, are 
inconsistent or do not accurately determine solvent loss, HAP content of 
the solvent, or the tons of oilseed processed.



Sec. 63.2852  What is a startup, shutdown, and malfunction plan?

    You must develop a written SSM plan in accordance with Sec. 
63.6(e)(3). You must complete the SSM plan before the compliance date 
for your source. You must also keep the SSM plan on-site and readily 
available as long as the source is operational. The SSM plan provides 
detailed procedures for operating and maintaining your source to 
minimize emissions during a qualifying SSM event for which the source 
chooses the Sec. 63.2850(e)(2) malfunction period, or the Sec. 
63.2850(c)(2) or (d)(2) initial startup period. The SSM plan must 
specify a program of corrective action for malfunctioning process and 
air pollution control equipment and reflect the best practices now in 
use by the industry to minimize emissions. Some or all of the procedures 
may come from plans you developed for other purposes such as a Standard 
Operating Procedure manual or an Occupational Safety and Health 
Administration Process Safety Management plan. To qualify as a SSM plan, 
other such plans must meet all the applicable requirements of these 
NESHAP.

[66 FR 19011, Apr. 12, 2001, as amended at 67 FR 16321, Apr. 5, 2002; 71 
FR 20463, Apr. 20, 2006]



Sec. 63.2853  How do I determine the actual solvent loss?

    By the end of each calendar month following an operating month, you 
must determine the total solvent loss in gallons for the previous 
operating month. The total solvent loss for an operating month includes 
all solvent losses that occur during normal operating periods within the 
operating month. If you have determined solvent losses for 12 or more 
operating months, then you must also determine the 12 operating months 
rolling sum of actual solvent loss in gallons by summing the monthly 
actual solvent loss for the previous 12 operating months. The 12 
operating months rolling sum of solvent loss is the ``actual solvent 
loss,'' which is used to calculate your compliance ratio as described in 
Sec. 63.2840.
    (a) To determine the actual solvent loss from your source, follow 
the procedures in your plan for demonstrating compliance to determine 
the items in paragraphs (a)(1) through (7) of this section:
    (1) The dates that define each operating status period during a 
calendar month. The dates that define each operating status period 
include the beginning date of each calendar month and the date of any 
change in the source operating status. If the source maintains the same 
operating status during an entire calendar month, these dates are the 
beginning and ending dates of the calendar month. If, prior to the 
effective date of this rule, your source determines the solvent loss on 
an accounting month, as defined in Sec. 63.2872, rather than a calendar 
month basis, and you have 12 complete accounting

[[Page 380]]

months of approximately equal duration in a calendar year, you may 
substitute the accounting month time interval for the calendar month 
time interval. If you choose to use an accounting month rather than a 
calendar month, you must document this measurement frequency selection 
in your plan for demonstrating compliance, and you must remain on this 
schedule unless you request and receive written approval from the agency 
responsible for these NESHAP.
    (2) Source operating status. You must categorize the operating 
status of your source for each recorded time interval in accordance with 
criteria in Table 1 of this section, as follows:

(v) Your source processes agricultural   An exempt period.
 products not defined as listed oilseed.
------------------------------------------------------------------------

    (3) Measuring the beginning and ending solvent inventory. You are 
required to measure and record the solvent inventory on the beginning 
and ending dates of each normal operating period that occurs during an 
operating month. An operating month is any calendar month with at least 
one normal operating period. You must consistently follow the procedures 
described in your plan for demonstrating compliance, as specified in 
Sec. 63.2851, to determine the extraction solvent inventory, and 
maintain readily available records of the actual solvent loss inventory, 
as described in Sec. 63.2862(c)(1). In general, you must measure and 
record the solvent inventory only when the source is actively processing 
any type of agricultural product. When the source is not active, some or 
all of the solvent working capacity is transferred to solvent storage 
tanks which can artificially inflate the solvent inventory.
    (4) Gallons of extraction solvent received. Record the total gallons 
of extraction solvent received in each shipment. For most processes, the 
gallons of solvent received represents purchases of delivered solvent 
added to the solvent storage inventory. However, if your process refines 
additional vegetable oil from off-site sources, recovers solvent from 
the off-site oil, and adds it to the on-site solvent inventory, then you 
must determine the quantity of recovered solvent and include it in the 
gallons of extraction solvent received.
    (5) Solvent inventory adjustments. In some situations, solvent 
losses determined directly from the measured solvent inventory and 
quantity of solvent received is not an accurate estimate of the ``actual 
solvent loss'' for use in determining compliance ratios. In such cases, 
you may adjust the total solvent loss for each normal operating period 
as long as you provide a reasonable justification for the adjustment. 
Situations that may require adjustments of the total solvent loss 
include, but are not limited to, situations in paragraphs (a)(5)(i) and 
(ii) of this section:
    (i) Solvent destroyed in a control device. You may use a control 
device to reduce solvent emissions to meet the emission standard. The 
use of a control device does not alter the emission limit for the 
source. If you use a control device that reduces solvent emissions 
through destruction of the solvent instead of recovery, then determine 
the gallons of solvent that enter the control device and are destroyed 
there during each normal operating period. All solvent destroyed in a 
control device during a

[[Page 381]]

normal operating period can be subtracted from the total solvent loss. 
Examples of destructive emission control devices include catalytic 
incinerators, boilers, or flares. Identify and describe, in your plan 
for demonstrating compliance, each type of reasonable and sound 
measurement method that you use to quantify the gallons of solvent 
entering and exiting the control device and to determine the destruction 
efficiency of the control device. You may use design evaluations to 
document the gallons of solvent destroyed or removed by the control 
device instead of performance testing under Sec. 63.7. The design 
evaluations must be based on the procedures and options described in 
Sec. 63.985(b)(1)(i)(A) through (C) or Sec. 63.11, as appropriate. All 
data, assumptions, and procedures used in such evaluations must be 
documented and available for inspection. If you use performance testing 
to determine solvent flow rate to the control device or destruction 
efficiency of the device, follow the procedures as outlined in Sec. 
63.997(e)(1) and (2). Instead of periodic performance testing to 
demonstrate continued good operation of the control device, you may 
develop a monitoring plan, following the procedures outlined in Sec. 
63.988(c) and using operational parametric measurement devices such as 
fan parameters, percent measurements of lower explosive limits, and 
combustion temperature.
    (ii) Changes in solvent working capacity. In records you keep on-
site, document any process modifications resulting in changes to the 
solvent working capacity in your vegetable oil production process. 
Solvent working capacity is defined in Sec. 63.2872. In general, 
solvent working capacity is the volume of solvent normally retained in 
solvent recovery equipment such as the extractor, desolventizer-toaster, 
solvent storage, working tanks, mineral oil absorber, condensers, and 
oil/solvent distillation system. If the change occurs during a normal 
operating period, you must determine the difference in working solvent 
volume and make a one-time documented adjustment to the solvent 
inventory.
    (b) Use Equation 1 of this section to determine the actual solvent 
loss occurring from your affected source for all normal operating 
periods recorded within a calendar month. Equation 1 of this section 
follows:
[GRAPHIC] [TIFF OMITTED] TR12AP01.003

Where:

SOLVB = Gallons of solvent in the inventory at the beginning 
          of normal operating period ``i'' as determined in paragraph 
          (a)(3) of this section.
SOLVE = Gallons of solvent in the inventory at the end of 
          normal operating period ``i'' as determined in paragraph 
          (a)(3) of this section.
SOLVR = Gallons of solvent received between the beginning and 
          ending inventory dates of normal operating period ``i'' as 
          determined in paragraph (a)(4) of this section.
SOLVA = Gallons of solvent added or removed from the 
          extraction solvent inventory during normal operating period 
          ``i'' as determined in paragraph (a)(5) of this section.
n = Number of normal operating periods in a calendar month.

    (c) The actual solvent loss is the total solvent losses during 
normal operating periods for the previous 12 operating months. You 
determine your actual solvent loss by summing the monthly actual solvent 
losses for the previous 12 operating months. You must record the actual 
solvent loss by the end of each calendar month following an operating 
month. Use the actual solvent loss in Equation 2 of Sec. 63.2840 to 
determine the compliance ratio. Actual solvent loss does not include 
losses that occur during operating status periods listed in paragraphs 
(c)(1) through (4) of this section. If any one of these four operating 
status periods span an entire month, then the month is treated as 
nonoperating

[[Page 382]]

and there is no compliance ratio determination.
    (1) Nonoperating periods as described in paragraph (a)(2)(ii) of 
this section.
    (2) Initial startup periods as described in Sec. 63.2850(c)(2) or 
(d)(2).
    (3) Malfunction periods as described in Sec. 63.2850(e)(2).
    (4) Exempt operation periods as described in paragraph (a)(2)(v) of 
this section.



Sec. 63.2854  How do I determine the weighted average volume fraction
of HAP in the actual solvent loss?

    (a) This section describes the information and procedures you must 
use to determine the weighted average volume fraction of HAP in 
extraction solvent received for use in your vegetable oil production 
process. By the end of each calendar month following an operating month, 
determine the weighted average volume fraction of HAP in extraction 
solvent received since the end of the previous operating month. If you 
have determined the monthly weighted average volume fraction of HAP in 
solvent received for 12 or more operating months, then also determine an 
overall weighted average volume fraction of HAP in solvent received for 
the previous 12 operating months. Use the volume fraction of HAP 
determined as a 12 operating months weighted average in Equation 2 of 
Sec. 63.2840 to determine the compliance ratio.
    (b) To determine the volume fraction of HAP in the extraction 
solvent determined as a 12 operating months weighted average, you must 
comply with paragraphs (b)(1) through (3) of this section:
    (1) Record the volume fraction of each HAP comprising more than 1 
percent by volume of the solvent in each delivery of solvent, including 
solvent recovered from off-site oil. To determine the HAP content of the 
material in each delivery of solvent, the reference method is EPA Method 
311 of appendix A of this part. You may use EPA Method 311, an approved 
alternative method, or any other reasonable means for determining the 
HAP content. Other reasonable means of determining HAP content include, 
but are not limited to, a material safety data sheet or a manufacturer's 
certificate of analysis. A certificate of analysis is a legal and 
binding document provided by a solvent manufacturer. The purpose of a 
certificate of analysis is to list the test methods and analytical 
results that determine chemical properties of the solvent and the volume 
percentage of all HAP components present in the solvent at quantities 
greater than 1 percent by volume. You are not required to test the 
materials that you use, but the Administrator may require a test using 
EPA Method 311 (or an approved alternative method) to confirm the 
reported HAP content. However, if the results of an analysis by EPA 
Method 311 are different from the HAP content determined by another 
means, the EPA Method 311 results will govern compliance determinations.
    (2) Determine the weighted average volume fraction of HAP in the 
extraction solvent each operating month. The weighted average volume 
fraction of HAP for an operating month includes all solvent received 
since the end of the last operating month, regardless of the operating 
status at the time of the delivery. Determine the monthly weighted 
average volume fraction of HAP by summing the products of the HAP volume 
fraction of each delivery and the volume of each delivery and dividing 
the sum by the total volume of all deliveries as expressed in Equation 1 
of this section. Record the result by the end of each calendar month 
following an operating month. Equation 1 of this section follows:
[GRAPHIC] [TIFF OMITTED] TR12AP01.004


[[Page 383]]


Where:

Receivedi = Gallons of extraction solvent received in 
          delivery ``i.''
Contenti = The volume fraction of HAP in extraction solvent 
          delivery ``i.''
Total Received = Total gallons of extraction solvent received since the 
          end of the previous operating month.
n = Number of extraction solvent deliveries since the end of the 
          previous operating month.

    (3) Determine the volume fraction of HAP in your extraction solvent 
as a 12 operating months weighted average. When your source has 
processed oilseed for 12 operating months, sum the products of the 
monthly weighted average HAP volume fraction and corresponding volume of 
solvent received, and divide the sum by the total volume of solvent 
received for the 12 operating months, as expressed by Equation 2 of this 
section. Record the result by the end of each calendar month following 
an operating month and use it in Equation 2 of Sec. 63.2840 to 
determine the compliance ratio. Equation 2 of this section follows:
[GRAPHIC] [TIFF OMITTED] TR12AP01.005

Where:

Receivedi = Gallons of extraction solvent received in 
          operating month ``i'' as determined in accordance with Sec. 
          63.2853(a)(4).
Contenti = Average volume fraction of HAP in extraction 
          solvent received in operating month ``i'' as determined in 
          accordance with paragraph (b)(1) of this section.
Total Received = Total gallons of extraction solvent received during the 
          previous 12 operating months.



Sec. 63.2855  How do I determine the quantity of oilseed processed?

    All oilseed measurements must be determined on an as received basis, 
as defined in Sec. 63.2872. The as received basis refers to the oilseed 
chemical and physical characteristics as initially received by the 
source and prior to any oilseed handling and processing. By the end of 
each calendar month following an operating month, you must determine the 
tons as received of each listed oilseed processed for the operating 
month. The total oilseed processed for an operating month includes the 
total of each oilseed processed during all normal operating periods that 
occur within the operating month. If you have determined the tons of 
oilseed processed for 12 or more operating months, then you must also 
determine the 12 operating months rolling sum of each type oilseed 
processed by summing the tons of each type of oilseed processed for the 
previous 12 operating months. The 12 operating months rolling sum of 
each type of oilseed processed is used to calculate the compliance ratio 
as described in Sec. 63.2840.
    (a) To determine the tons as received of each type of oilseed 
processed at your source, follow the procedures in your plan for 
demonstrating compliance to determine the items in paragraphs (a)(1) 
through (5) of this section:
    (1) The dates that define each operating status period. The dates 
that define each operating status period include the beginning date of 
each calendar month and the date of any change in the source operating 
status. If, prior to the effective date of this rule, your source 
determines the oilseed inventory on an accounting month rather than a 
calendar month basis, and you have 12 complete accounting months of 
approximately equal duration in a calendar year, you may substitute the 
accounting month time interval for the calendar month time interval. If 
you choose to use an accounting month rather than a calendar month, you 
must document this measurement frequency selection in your plan for 
demonstrating compliance, and you must remain on this schedule unless 
you request and receive written approval from the agency responsible for 
these

[[Page 384]]

NESHAP. The dates on each oilseed inventory log must be consistent with 
the dates recorded for the solvent inventory.
    (2) Source operating status. You must categorize the source 
operation for each recorded time interval. The source operating status 
for each time interval recorded on the oilseed inventory for each type 
of oilseed must be consistent with the operating status recorded on the 
solvent inventory logs as described in Sec. 63.2853(a)(2).
    (3) Measuring the beginning and ending inventory for each oilseed. 
You are required to measure and record the oilseed inventory on the 
beginning and ending dates of each normal operating period that occurs 
during an operating month. An operating month is any calendar month with 
at least one normal operating period. You must consistently follow the 
procedures described in your plan for demonstrating compliance, as 
specified in Sec. 63.2851, to determine the oilseed inventory on an as 
received basis and maintain readily available records of the oilseed 
inventory as described by Sec. 63.2862(c)(3).
    (4) Tons of each oilseed received. Record the type of oilseed and 
tons of each shipment of oilseed received and added to your on-site 
storage.
    (5) Oilseed inventory adjustments. In some situations, determining 
the quantity of oilseed processed directly from the measured oilseed 
inventory and quantity of oilseed received is not an accurate estimate 
of the tons of oilseed processed for use in determining compliance 
ratios. For example, spoiled and molded oilseed removed from storage but 
not processed by your source will result in an overestimate of the 
quantity of oilseed processed. In such cases, you must adjust the 
oilseed inventory and provide a justification for the adjustment. 
Situations that may require oilseed inventory adjustments include, but 
are not limited to, the situations listed in paragraphs (a)(5)(i) 
through (v) of this section:
    (i) Oilseed that mold or otherwise become unsuitable for processing.
    (ii) Oilseed you sell before it enters the processing operation.
    (iii) Oilseed destroyed by an event such as a process malfunction, 
fire, or natural disaster.
    (iv) Oilseed processed through operations prior to solvent 
extraction such as screening, dehulling, cracking, drying, and 
conditioning; but that are not routed to the solvent extractor for 
further processing.
    (v) Periodic physical measurements of inventory. For example, some 
sources periodically empty oilseed storage silos to physically measure 
the current oilseed inventory. This periodic measurement procedure 
typically results in a small inventory correction. The correction 
factor, usually less than 1 percent, may be used to make an adjustment 
to the source's oilseed inventory that was estimated previously with 
indirect measurement techniques. To make this adjustment, your plan for 
demonstrating compliance must provide for such an adjustment.
    (b) Use Equation 1 of this section to determine the quantity of each 
oilseed type processed at your affected source during normal operating 
periods recorded within a calendar month. Equation 1 of this section 
follows:
[GRAPHIC] [TIFF OMITTED] TR12AP01.000

Where:

SEEDB = Tons of oilseed in the inventory at the beginning of 
          normal operating period ``i'' as determined in accordance with 
          paragraph (a)(3) of this section.
SEEDE = Tons of oilseed in the inventory at the end of normal 
          operating period ``i'' as determined in accordance with 
          paragraph (a)(3) of this section.
SEEDR = Tons of oilseed received during normal operating 
          period ``i'' as determined in accordance with paragraph (a)(4) 
          of this section.
SEEDA = Tons of oilseed added or removed from the oilseed 
          inventory during normal

[[Page 385]]

          operating period ``i'' as determined in accordance with 
          paragraph (a)(5) of this section.
n = Number of normal operating periods in the calendar month during 
          which this type oilseed was processed.

    (c) The quantity of each oilseed processed is the total tons of each 
type of listed oilseed processed during normal operating periods in the 
previous 12 operating months. You determine the tons of each oilseed 
processed by summing the monthly quantity of each oilseed processed for 
the previous 12 operating months. You must record the 12 operating 
months quantity of each type of oilseed processed by the end of each 
calendar month following an operating month. Use the 12 operating months 
quantity of each type of oilseed processed to determine the compliance 
ratio as described in Sec. 63.2840. The quantity of oilseed processed 
does not include oilseed processed during the operating status periods 
in paragraphs (c)(1) through (4) of this section:
    (1) Nonoperating periods as described in Sec. 63.2853 (a)(2)(ii).
    (2) Initial startup periods as described in Sec. 63.2850(c)(2) or 
(d)(2).
    (3) Malfunction periods as described in Sec. 63.2850(e)(2).
    (4) Exempt operation periods as described in Sec. 63.2853 
(a)(2)(v).
    (5) If any one of these four operating status periods span an entire 
calendar month, then the calendar month is treated as a nonoperating 
month and there is no compliance ratio determination.

                   Notifications, Reports, and Records



Sec. 63.2860  What notifications must I submit and when?

    You must submit the one-time notifications listed in paragraphs (a) 
through (d) of this section to the responsible agency:
    (a) Initial notification for existing sources. For an existing 
source, submit an initial notification to the agency responsible for 
these NESHAP no later than 120 days after the effective date of this 
subpart. In the notification, include the items in paragraphs (a)(1) 
through (5) of this section:
    (1) The name and address of the owner or operator.
    (2) The physical address of the vegetable oil production process.
    (3) Identification of the relevant standard, such as the vegetable 
oil production NESHAP, and compliance date.
    (4) A brief description of the source including the types of listed 
oilseeds processed, nominal operating capacity, and type of 
desolventizer(s) used.
    (5) A statement designating the source as a major source of HAP or a 
demonstration that the source meets the definition of an area source. An 
area source is a source that is not a major source and is not collocated 
within a plant site with other sources that are individually or 
collectively a major source.
    (b) Initial notifications for new and reconstructed sources. New or 
reconstructed sources must submit a series of notifications before, 
during, and after source construction per the schedule listed in Sec. 
63.9. The information requirements for the notifications are the same as 
those listed in the General Provisions with the exceptions listed in 
paragraphs (b)(1) and (2) of this section:
    (1) The application for approval of construction does not require 
the specific HAP emission data required in Sec. 63.5(d)(1)(ii)(H) and 
(iii), (d)(2) and (d)(3)(ii). The application for approval of 
construction would include, instead, a brief description of the source 
including the types of listed oilseeds processed, nominal operating 
capacity, and type of desolventizer(s) used.
    (2) The notification of actual startup date must also include 
whether you have elected to operate under an initial startup period 
subject to Sec. 63.2850(c)(2) and provide an estimate and justification 
for the anticipated duration of the initial startup period.
    (c) Significant modification notifications. Any existing or new 
source that plans to undergo a significant modification as defined in 
Sec. 63.2872 must submit two reports as described in paragraphs (c)(1) 
and (2) of this section:
    (1) Initial notification. You must submit an initial notification to 
the agency responsible for these NESHAP 30 days prior to initial startup 
of the significantly modified source. The initial notification must 
demonstrate that the

[[Page 386]]

proposed changes qualify as a significant modification. The initial 
notification must include the items in paragraphs (c)(1)(i) and (ii) of 
this section:
    (i) The expected startup date of the modified source.
    (ii) A description of the significant modification including a list 
of the equipment that will be replaced or modified. If the significant 
modification involves changes other than adding or replacing extractors, 
desolventizer-toasters (conventional and specialty), and meal dryer-
coolers, then you must also include the fixed capital cost of the new 
components, expressed as a percentage of the fixed capital cost to build 
a comparable new vegetable oil production process; supporting 
documentation for the cost estimate; and documentation that the proposed 
changes will significantly affect solvent losses.
    (2) Notification of actual startup. You must submit a notification 
of actual startup date within 15 days after initial startup of the 
modified source. The notification must include the items in paragraphs 
(c)(2)(i) through (iv) of this section:
    (i) The initial startup date of the modified source.
    (ii) An indication whether you have elected to operate under an 
initial startup period subject to Sec. 63.2850(d)(2).
    (iii) The anticipated duration of any initial startup period.
    (iv) A justification for the anticipated duration of any initial 
startup period.
    (d) Notification of compliance status. As an existing, new, or 
reconstructed source, you must submit a notification of compliance 
status report to the responsible agency no later than 60 days after 
determining your initial 12 operating months compliance ratio. If you 
are an existing source, you generally must submit this notification no 
later than 50 calendar months after the effective date of these NESHAP 
(36 calendar months for compliance, 12 operating months to record data, 
and 2 calendar months to complete the report). If you are a new or 
reconstructed source, the notification of compliance status is generally 
due no later than 20 calendar months after initial startup (6 calendar 
months for the initial startup period, 12 operating months to record 
data, and 2 calendar months to complete the report). The notification of 
compliance status must contain the items in paragraphs (d)(1) through 
(6) of this section:
    (1) The name and address of the owner or operator.
    (2) The physical address of the vegetable oil production process.
    (3) Each listed oilseed type processed during the previous 12 
operating months.
    (4) Each HAP identified under Sec. 63.2854(a) as being present in 
concentrations greater than 1 percent by volume in each delivery of 
solvent received during the 12 operating months period used for the 
initial compliance determination.
    (5) A statement designating the source as a major source of HAP or a 
demonstration that the source qualifies as an area source. An area 
source is a source that is not a major source and is not collocated 
within a plant site with other sources that are individually or 
collectively a major source.
    (6) A compliance certification indicating whether the source 
complied with all of the requirements of this subpart throughout the 12 
operating months used for the initial source compliance determination. 
This certification must include a certification of the items in 
paragraphs (d)(6)(i) through (iii) of this section:
    (i) The plan for demonstrating compliance (as described in Sec. 
63.2851) and SSM plan (as described in Sec. 63.2852) are complete and 
available on-site for inspection.
    (ii) You are following the procedures described in the plan for 
demonstrating compliance.
    (iii) The compliance ratio is less than or equal to 1.00.



Sec. 63.2861  What reports must I submit and when?

    After the initial notifications, you must submit the reports in 
paragraphs (a) through (d) of this section to the agency responsible for 
these NESHAP at the appropriate time intervals:
    (a) Annual compliance certifications. The first annual compliance 
certification is due 12 calendar months after

[[Page 387]]

you submit the notification of compliance status. Each subsequent annual 
compliance certification is due 12 calendar months after the previous 
annual compliance certification. The annual compliance certification 
provides the compliance status for each operating month during the 12 
calendar months period ending 60 days prior to the date on which the 
report is due. Include the information in paragraphs (a)(1) through (6) 
of this section in the annual certification:
    (1) The name and address of the owner or operator.
    (2) The physical address of the vegetable oil production process.
    (3) Each listed oilseed type processed during the 12 calendar months 
period covered by the report.
    (4) Each HAP identified under Sec. 63.2854(a) as being present in 
concentrations greater than 1 percent by volume in each delivery of 
solvent received during the 12 calendar months period covered by the 
report.
    (5) A statement designating the source as a major source of HAP or a 
demonstration that the source qualifies as an area source. An area 
source is a source that is not a major source and is not collocated 
within a plant site with other sources that are individually or 
collectively a major source.
    (6) A compliance certification to indicate whether the source was in 
compliance for each compliance determination made during the 12 calendar 
months period covered by the report. For each such compliance 
determination, you must include a certification of the items in 
paragraphs (a)(6)(i) through (ii) of this section:
    (i) You are following the procedures described in the plan for 
demonstrating compliance.
    (ii) The compliance ratio is less than or equal to 1.00.
    (b) Deviation notification report. Submit a deviation report for 
each compliance determination you make in which the compliance ratio 
exceeds 1.00 as determined under Sec. 63.2840(c). Submit the deviation 
report by the end of the month following the calendar month in which you 
determined the deviation. The deviation notification report must include 
the items in paragraphs (b)(1) through (4) of this section:
    (1) The name and address of the owner or operator.
    (2) The physical address of the vegetable oil production process.
    (3) Each listed oilseed type processed during the 12 operating 
months period for which you determined the deviation.
    (4) The compliance ratio comprising the deviation. You may reduce 
the frequency of submittal of the deviation notification report if the 
agency responsible for these NESHAP does not object as provided in Sec. 
63.10(e)(3)(iii).
    (c) Periodic startup, shutdown, and malfunction report. If you 
choose to operate your source under an initial startup period subject to 
Sec. 63.2850(c)(2) or (d)(2) or a malfunction period subject to Sec. 
63.2850(e)(2), you must submit a periodic SSM report by the end of the 
calendar month following each month in which the initial startup period 
or malfunction period occurred. The periodic SSM report must include the 
items in paragraphs (c)(1) through (3) of this section:
    (1) The name, title, and signature of a source's responsible 
official who is certifying that the report accurately states that all 
actions taken during the initial startup or malfunction period were 
consistent with the SSM plan.
    (2) A description of events occurring during the time period, the 
date and duration of the events, and reason the time interval qualifies 
as an initial startup period or malfunction period.
    (3) An estimate of the solvent loss during the initial startup or 
malfunction period with supporting documentation.
    (d) Immediate SSM reports. If you handle a SSM during an initial 
startup period subject to Sec. 63.2850(c)(2) or (d)(2) or a malfunction 
period subject to Sec. 63.2850(e)(2) differently from procedures in the 
SSM plan and the relevant emission requirements in Sec. 63.2840 are 
exceeded, then you must submit an immediate SSM report. Immediate SSM 
reports consist of a telephone call or facsimile transmission to the 
responsible agency within 2 working days after starting actions 
inconsistent with the SSM plan, followed by a letter within 7 working 
days after the end of the event. The letter must include the

[[Page 388]]

items in paragraphs (d)(1) through (3) of this section:
    (1) The name, title, and signature of a source's responsible 
official who is certifying the accuracy of the report, an explanation of

Sec. 63.2862  What records must I keep?

    (a) You must satisfy the recordkeeping requirements of this section 
by the compliance date for your source specified in Table 1 of Sec. 
63.2834.
    (b) Prepare a plan for demonstrating compliance (as described in 
Sec. 63.2851) and a SSM plan (as described in Sec. 63.2852). In these 
two plans, describe the procedures you will follow in obtaining and 
recording data, and determining compliance under normal operations or a 
SSM subject to the Sec. 63.2850(c)(2) or (d)(2) initial startup period 
or the Sec. 63.2850(e)(2) malfunction period. Complete both plans 
before the compliance date for your source and keep them on-site and 
readily available as long as the source is operational.
    (c) If your source processes any listed oilseed, record the items in 
paragraphs (c)(1) through (5) of this section:
    (1) For the solvent inventory, record the information in paragraphs 
(c)(1)(i) through (vii) of this section in accordance with your plan for 
demonstrating compliance:
    (i) Dates that define each operating status period during a calendar 
month.
    (ii) The operating status of your source such as normal operation, 
nonoperating, initial startup period, malfunction period, or exempt 
operation for each recorded time interval.
    (iii) Record the gallons of extraction solvent in the inventory on 
the beginning and ending dates of each normal operating period.
    (iv) The gallons of all extraction solvent received, purchased, and 
recovered during each calendar month.
    (v) All extraction solvent inventory adjustments, additions or 
subtractions. You must document the reason for the adjustment and 
justify the quantity of the adjustment.
    (vi) The total solvent loss for each calendar month, regardless of 
the source operating status.
    (vii) The actual solvent loss in gallons for each operating month.
    (2) For the weighted average volume fraction of HAP in the 
extraction solvent, you must record the items in paragraphs (c)(2)(i) 
through (iii) of this section:
    (i) The gallons of extraction solvent received in each delivery.
    (ii) The volume fraction of each HAP exceeding 1 percent by volume 
in each delivery of extraction solvent.
    (iii) The weighted average volume fraction of HAP in extraction 
solvent received since the end of the last operating month as determined 
in accordance with Sec. 63.2854(b)(2).
    (3) For each type of listed oilseed processed, record the items in 
paragraphs (c)(3)(i) through (vi) of this section, in accordance with 
your plan for demonstrating compliance:
    (i) The dates that define each operating status period. These dates 
must be the same as the dates entered for the extraction solvent 
inventory.
    (ii) The operating status of your source such as normal operation, 
nonoperating, initial startup period, malfunction period, or exempt 
operation for each recorded time interval. On the log for each type of 
listed oilseed that is not being processed during a normal operating 
period, you must record which type of listed oilseed is being processed 
in addition to the source operating status.
    (iii) The oilseed inventory for the type of listed oilseed being 
processed on the beginning and ending dates of each normal operating 
period.
    (iv) The tons of each type of listed oilseed received at the 
affected source each normal operating period.
    (v) All listed oilseed inventory adjustments, additions or 
subtractions for normal operating periods. You must document the reason 
for the adjustment and justify the quantity of the adjustment.
    (vi) The tons of each type of listed oilseed processed during each 
operating month.

    (d) After your source has processed listed oilseed for 12 operating 
months, and you are not operating during an initial startup period as 
described in Sec. 63.2850(c)(2) or (d)(2), or a malfunction period as 
described in Sec. 63.2850(e)(2), record the items in paragraphs (d)(1) 
through (5) of this section by the end of the calendar month following 
each operating month:
    (1) The 12 operating months rolling sum of the actual solvent loss 
in gallons as described in Sec. 63.2853(c).
    (2) The weighted average volume fraction of HAP in extraction 
solvent received for the previous 12 operating months as described in 
Sec. 63.2854(b)(3).
    (3) The 12 operating months rolling sum of each type of listed 
oilseed processed at the affected source in tons as described in Sec. 
63.2855(c).
    (4) A determination of the compliance ratio. Using the values from 
Sec. Sec. 63.2853, 63.2854, 63.2855, and Table 1 of Sec. 63.2840, 
calculate the compliance ratio using Equation 2 of Sec. 63.2840.
    (5) A statement of whether the source is in compliance with all of 
the requirements of this subpart. This includes a determination of 
whether you have met all of the applicable requirements in Sec. 
63.2850.
    (e) For each SSM event subject to an initial startup period as 
described in Sec. 63.2850(c)(2) or (d)(2), or a malfunction period as 
described in Sec. 63.2850(e)(2), record the items in paragraphs (e)(1) 
through (3) of this section by the end of the calendar month following 
each month in which the initial startup period or malfunction period 
occurred:
    (1) A description and date of the SSM event, its duration, and 
reason it qualifies as an initial startup or malfunction.
    (2) An estimate of the solvent loss in gallons for the duration of 
the initial startup or malfunction period with supporting documentation.
    (3) A checklist or other mechanism to indicate whether the SSM plan 
was followed during the initial startup or malfunction period.



Sec. 63.2863  In what form and how long must I keep my records?

    (a) Your records must be in a form suitable and readily available 
for review in accordance with Sec. 63.10(b)(1).
    (b) As specified in Sec. 63.10(b)(1), you must keep each record for 
5 years following the date of each occurrence, measurement, maintenance, 
corrective action, report, or record.
    (c) You must keep each record on-site for at least 2 years after the 
date of each occurrence, measurement, maintenance, corrective action, 
report, or record, in accordance with Sec. 3.10(b)(1). You can keep the 
records off-site for the remaining 3 years.

Sec. 63.2871  Who implements and enforces this subpart?

    (a) This subpart can be implemented by us, the U.S. EPA, or a 
delegated authority such as your State, local, or tribal agency. If the 
U.S. EPA Administrator has delegated authority to your State, local, or 
tribal agency, then that agency, as well as the U.S. EPA, has the 
authority to implement and enforce this subpart. You should contact your 
U.S. EPA Regional Office to find out if this subpart is delegated to 
your State, local, or tribal agency.
    (b) In delegating implementation and enforcement authority of this 
subpart to a State, local, or tribal agency under section 40 CFR part 
63, subpart E, the authorities contained in paragraph (c) of this 
section are retained by the Administrator of the U.S. EPA and are not 
transferred to the State, local, or tribal agency.
    (c) The authorities that will not be delegated to State, local, or 
tribal agencies are as follows:
    (1) Approval of alternative nonopacity emissions standards under 
Sec. 63.6(g).
    (2) Approval of alternative opacity standards under Sec. 
63.6(h)(9).
    (3) Approval of major alternatives to test methods under Sec. 
63.7(e)(2)(ii) and (f) and as defined in Sec. 63.90.
    (4) Approval of major alternatives to monitoring under Sec. 63.8(f) 
and as defined in Sec. 63.90.
    (5) Approval of major alternatives to recordkeeping and reporting 
under Sec. 63.10(f) and as defined in Sec. 63.90.



Sec. 63.2872  What definitions apply to this subpart?

    Terms used in this subpart are defined in the sources listed:
    (a) The Clean Air Act, section 112(a).
    (b) In 40 CFR 63.2, the NESHAP General Provisions.
    (c) In this section as follows:
    Accounting month means a time interval defined by a business firm 
during which corporate economic and financial factors are determined on 
a consistent and regular basis. An accounting month will consist of 
approximately 4 to 5 calendar weeks and each accounting month will be of 
approximate equal duration. An accounting month may not correspond 
exactly to a calendar month, but 12 accounting months will correspond 
exactly to a calendar year.
    Actual solvent loss means the gallons of solvent lost from a source 
during 12 operating months as determined in accordance with Sec. 
63.2853.
    Agricultural product means any commercially grown plant or plant 
product.
    Allowable HAP loss means the gallons of HAP that would have been 
lost from a source if the source was operating at the solvent loss 
factor for each listed oilseed type. The allowable HAP loss in gallons 
is determined by multiplying

[[Page 393]]

the tons of each oilseed type processed during the previous 12 operating 
months, as determined in accordance with Sec. 63.2855, by the 
corresponding oilseed solvent loss factor (gal/ton) listed in Table 1 of 
Sec. 63.2840, and by the dimensionless constant 0.64, and summing the 
result for all oilseed types processed.
    Area source means any source that does not meet the major source 
definition.
    As received is the basis upon which all oilseed measurements must be 
determined and refers to the oilseed chemical and physical 
characteristics as initially received by the source and prior to any 
oilseed handling and processing.
    Batch operation means any process that operates in a manner where 
the addition of raw material and withdrawal of product do not occur 
simultaneously. Typically, raw material is added to a process, 
operational steps occur, and a product is removed from the process. More 
raw material is then added to the process and the cycle repeats.
    Calendar month means 1 month as specified in a calendar.
    Compliance date means the date on which monthly compliance 
recordkeeping begins. For existing sources, recordkeeping typically 
begins 3 years after the effective date of the subpart. For new and 
reconstructed sources, recordkeeping typically begins upon initial 
startup, except as noted in Sec. 63.2834.
    Compliance ratio means a ratio of the actual HAP loss in gallons 
from the previous 12 operating months to an allowable HAP loss in 
gallons, which is determined by using oilseed solvent loss factors in 
Table 1 of Sec. 63.2840, the weighted average volume fraction of HAP in 
solvent received for the previous 12 operating months, and the tons of 
each type of listed oilseed processed in the previous 12 operating 
months. Months during which no listed oilseed is processed, or months 
during which the Sec. 63.2850(c)(2) or (d)(2) initial startup period or 
the Sec. 63.2850(e)(2) malfunction period applies, are excluded from 
this calculation. Equation 2 of Sec. 63.2840 is used to calculate this 
value. If the value is less than or equal to 1.00, the source is in 
compliance. If the value is greater than 1.00, the source is deviating 
from compliance.
    Continuous operation means any process that adds raw material and 
withdraws product simultaneously. Mass, temperature, concentration and 
other properties typically approach steady-state conditions.
    Conventional desolventizer means a desolventizer toaster that 
operates with indirect and direct-contact steam to remove solvent from 
the extracted meal. Oilseeds processed in a conventional desolventizer 
produce crude vegetable oil and crude meal products, such as animal 
feed.
    Corn germ dry milling means a source that processes corn germ that 
has been separated from the other corn components using a ``dry'' 
process of mechanical chafing and air sifting.
    Corn germ wet milling means a source that processes corn germ that 
has been separated from other corn components using a ``wet'' process of 
centrifuging a slurry steeped in a dilute sulfurous acid solution.
    Exempt period means a period of time during which a source processes 
agricultural products not defined as listed oilseed.
    Extraction solvent means an organic chemical medium used to remove 
oil from an oilseed. Typically, the extraction solvent is a commercial 
grade of hexane isomers which have an approximate HAP content of 64 
percent by volume.
    Hazardous air pollutant (HAP) means any substance or mixture of 
substances listed as a hazardous air pollutant under section 112(b) of 
the Clean Air Act, as of April 12, 2001.
    Initial startup date means the first calendar day that a new, 
reconstructed or significantly modified source processes any listed 
oilseed.
    Initial startup period means a period of time from the initial 
startup date of a new, reconstructed or significantly modified source, 
for which you choose to operate the source under an initial startup 
period subject to Sec. 63.2850(c)(2) or (d)(2). During an initial 
startup period, a source complies with the standards by minimizing HAP 
emissions to the extent practical. The initial startup period following 
initial startup of a new or reconstructed source may not

[[Page 394]]

exceed 6 calendar months. The initial startup period following a 
significant modification may not exceed 3 calendar months. Solvent and 
oilseed inventory information recorded during the initial startup period 
is excluded from use in any compliance ratio determinations.
    Large cottonseed plant means a vegetable oil production process that 
processes 120,000 tons or more of cottonseed and other listed oilseed 
during all normal operating periods in a 12 operating months period used 
to determine compliance.
    Malfunction period means a period of time between the beginning and 
end of a process malfunction and the time reasonably necessary for a 
source to correct the malfunction for which you choose to operate the 
source under a malfunction period subject to Sec. 63.2850(e)(2). This 
period may include the duration of an unscheduled process shutdown, 
continued operation during a malfunction, or the subsequent process 
startup after a shutdown resulting from a malfunction. During a 
malfunction period, a source complies with the standards by minimizing 
HAP emissions to the extent practical. Therefore, solvent and oilseed 
inventory information recorded during a malfunction period is excluded 
from use in any compliance ratio determinations.
    Mechanical extraction means removing vegetable oil from oilseeds 
using only mechanical devices such as presses or screws that physically 
force the oil from the oilseed. Mechanical extraction techniques use no 
organic solvents to remove oil from an oilseed.
    Nonoperating period means any period of time in which a source 
processes no agricultural product. This operating status does not apply 
during any period in which the source operates under an initial startup 
period as described in Sec. 63.2850(c)(2) or (d)(2), or a malfunction 
period, as described in Sec. 63.2850(e)(2).
    Normal operating period means any period of time in which a source 
processes a listed oilseed that is not categorized as an initial startup 
period as described in Sec. 63.2850(c)(2) or (d)(2), or a malfunction 
period, as described in Sec. 63.2850(e)(2). At the beginning and ending 
dates of a normal operating period, solvent and oilseed inventory 
information is recorded and included in the compliance ratio 
determination.
    Oilseed or listed oilseed means the following agricultural products: 
corn germ, cottonseed, flax, peanut, rapeseed (for example, canola), 
safflower, soybean, and sunflower.
    Oilseed solvent loss factor means a ratio expressed as gallons of 
solvent loss per ton of oilseed processed. The solvent loss factors are 
presented in Table 1 of Sec. 63.2840 and are used to determine the 
allowable HAP loss.
    Operating month means any calendar or accounting month in which a 
source processes any quantity of listed oilseed, excluding any entire 
calendar or accounting month in which the source operated under an 
initial startup period as described in Sec. 63.2850(c)(2) or (d)(2), or 
a malfunction period as described in Sec. 63.2850(e)(2). An operating 
month may include time intervals characterized by several types of 
operating status. However, an operating month must have at least one 
normal operating period.
    Significant modification means the addition of new equipment or the 
modification of existing equipment that:
    (1) Significantly affects solvent losses from your vegetable oil 
production process;
    (2) The fixed capital cost of the new components represents a 
significant percentage of the fixed capital cost of building a 
comparable new vegetable oil production process;
    (3) The fixed capital cost of the new equipment does not constitute 
reconstruction as defined in Sec. 63.2; and
    (4) Examples of significant modifications include replacement of or 
major changes to solvent recovery equipment such as extractors, 
desolventizer-toasters/dryer-coolers, flash desolventizers, and 
distillation equipment associated with the mineral oil system, and 
equipment affecting desolventizing efficiency and steady-state operation 
of your vegetable oil production process such as flaking mills, oilseed 
heating and conditioning equipment, and cracking mills.

normal operating periods in a 12 operating months period used to 
determine compliance.
    Solvent extraction means removing vegetable oil from listed oilseed 
using an organic solvent in a direct-contact system.
    Solvent working capacity means the volume of extraction solvent 
normally retained in solvent recovery equipment. Examples include 
components such as the solvent extractor, desolventizer-toaster, solvent 
storage and working tanks, mineral oil absorption system, condensers, 
and oil/solvent distillation system.
    Specialty desolventizer means a desolventizer that removes excess 
solvent from soybean meal using vacuum conditions, energy from 
superheated solvent vapors, or reduced operating conditions (e.g., 
temperature) as compared to the typical operation of a conventional 
desolventizer. Soybeans processed in a specialty desolventizer result in 
high-protein vegetable meal products for human and animal consumption, 
such as calf milk replacement products and meat extender products.
    Vegetable oil production process means the equipment comprising a 
continuous process for producing crude vegetable oil and meal products, 
including specialty soybean products, in which oil is removed from 
listed oilseeds through direct contact with an organic solvent. Process 
equipment typically includes the following components: oilseed 
preparation operations (including conditioning, drying, dehulling, and 
cracking), solvent extractors, desolventizer-toasters, meal dryers, meal 
coolers, meal conveyor systems, oil distillation units, solvent 
evaporators and condensers, solvent recovery system (also referred to as 
a mineral oil absorption system), vessels storing solvent-laden 
materials, and crude meal packaging and storage vessels. A vegetable oil 
production process does not include vegetable oil refining operations 
(including operations such as bleaching, hydrogenation, and deodorizing) 
and operations that engage in additional chemical treatment of crude 
soybean meals produced in specialty desolventizer units (including 
operations such as soybean isolate production).

    You must comply with this subpart if you meet the criteria in 
paragraphs (a) and (b) of this section:
    (a) You own or operate a drying and curing oven at a wet-formed 
fiberglass mat production facility.
    (b) Your drying and curing oven or the facility at which your drying 
and curing oven is located is a major source of hazardous air pollutants 
(HAP). A major source is any stationary source or group of stationary 
sources located within a contiguous area and under common control that 
emits or can potentially emit, considering controls, in the aggregate, 
9.07 megagrams (10 tons) or more per year of a single HAP or 22.68 
megagrams (25 tons) or more per year of any combination of HAP.



Sec. 63.2982  What parts of my plant does this subpart cover?

    (a) This subpart applies to each new, reconstructed, or existing 
affected source. The affected source (the portion of your plant covered 
by this subpart) is each wet-formed fiberglass mat drying and curing 
oven.

[[Page 396]]

    (b) An affected source is a new affected source if you commenced 
construction of the affected source after May 26, 2000, and you meet the 
applicability criteria in Sec. 63.2981 at start-up.
    (c) An affected source is reconstructed if you meet the criteria as 
defined in Sec. 63.2.

compliance with the emissions and operating limits. Table 1 of this 
subpart establishes the minimum recordkeeping requirements.



Sec. 63.2988  [Reserved]



Sec. 63.2989  How do I change my OMM plan?

    Changes to the operating limits or ranges in your OMM plan require a 
new performance test.
    (a) In order to revise the ranges or levels established for your 
operating limits in Sec. 63.2984, you must meet the requirements in 
paragraphs (a)(1) and (2) of this section:
    (1) Submit a notification of performance test to the Administrator 
as specified in Sec. 63.7(b) to revise your operating ranges or limits.
    (2) After completing the performance test to demonstrate that 
compliance with the emissions limits can be achieved at the revised 
levels of the operating limits, you must submit the performance test 
results and the revised operating limits as part of the notification of 
compliance status required under Sec. 63.9(h).
    (b) If you are revising the inspection and maintenance procedures in 
your plan that are specified in Sec. 63.2987(b), you do not need to 
conduct a new performance test.
    (c) If you plan to operate your process or control device under 
alternative operating conditions and do not wish to revise your OMM plan 
when you change operating conditions, you can perform a separate 
compliance test to establish operating limits for each condition. You 
can then include the operating limits for each condition in your OMM 
plan. After completing the performance tests, you must record the date 
and time when you change operations from one condition to another, the 
condition under which you are operating, and the operating limits that 
apply under that condition. If you can perform a single performance test 
that establishes the most stringent operating limits that cover all 
alternative operating conditions, then you do not need to comply with 
the provisions of this paragraph.

Where:

UF solids/hour = UF resin solids application rate (pounds per hour).
LOI = loss on ignition (weight faction), or pound of organic binder per 
          pound of mat.
UFL = UF-to-latex ratio in the binder (mass fraction of UF resin solids 
          in total combined resin solids for UF and latex), or pound of 
          UF solids per pound of total resin solids (UF and latex).

Sec. Appendix A to Subpart HHHH of Part 63--Method for Determining Free-
   Formaldehyde in Urea-Formaldehyde Resins by Sodium Sulfite (Iced & 
                                 Cooled)

                                1.0 Scope

    This procedure corresponds to the Housing and Urban Development 
method of determining free-formaldehyde in urea-formaldehyde resins. 
This method applies to samples that decompose to yield formaldehyde 
under the conditions of other free-formaldehyde methods. The primary use 
is for urea-formaldehyde resins.

                       2.0 Part A--Testing Resins

    Formaldehyde will react with sodium sulfite to form the sulfite 
addition products and liberate sodium hydroxide (NaOH); however, at room 
temperature, the methanol groups present will also react to liberate 
NaOH. Titrate at 0 degrees Celsius (( [deg]deg;C) to minimize the 
reaction of the methanol groups.
    2.1 Apparatus Required.
    2.1.1 Ice crusher.
    2.1.2 One 100-milliliter (mL) graduated cylinder.
    2.1.3 Three 400-mL beakers.
    2.1.4 One 50-mL burette.
    2.1.5 Analytical balance accurate to 0.1 milligrams (mg).
    2.1.6 Magnetic stirrer.
    2.1.7 Magnetic stirring bars.

[[Page 408]]

    2.1.8 Disposable pipettes.
    2.1.9 Several 5-ounce (oz.) plastic cups.
    2.1.10 Ice cube trays (small cubes).
    2.2 Materials Required.
    2.2.1 Ice cubes (made with distilled water).
    2.2.2 A solution of 1 molar (M) sodium sulfite 
(Na2SO3) (63 grams (g) 
Na2SO3/500 mL water (H2O) neutralized 
to thymolphthalein endpoint).
    2.2.3 Standardized 0.1 normal (N) hydrochloric acid (HCl).
    2.2.4 Thymolphthalein indicator (1.0 g thymolphthalein/199 g 
methanol).
    2.2.5 Sodium chloride (NaCl) (reagent grade).
    2.2.6 Sodium hydroxide (NaOH).
    2.3 Procedure.
    2.3.1 Prepare sufficient quantity of crushed ice for three 
determinations (two trays of cubes).
    2.3.2 Put 70 cubic centimeters (cc) of 1 M 
Na2SO3 solution into a 400-mL beaker. Begin 
stirring and add approximately 100 g of crushed ice and 2 g of NaCl. 
Maintain 0 [deg]C during test, adding ice as necessary.
    2.3.3 Add 10-15 drops of thymolphthalein indicator to the chilled 
solution. If the solution remains clear, add 0.1 N NaOH until the 
solution turns blue; then add 0.1 N HCl back to the colorless endpoint. 
If the solution turns blue upon adding the indicator, add 0.1 N HCl to 
the colorless endpoint.
    2.3.4 On the analytical balance, accurately weigh the amount of 
resin indicated under the ``Resin Sample Size'' chart (see below) as 
follows.

    2.3.4.1 Pour about 1 inch of resin into a 5 oz. plastic cup.
    2.3.4.2 Determine the gross weight of the cup, resin, and disposable 
pipette (with the narrow tip broken off) fitted with a small rubber 
bulb.
    2.3.4.3 Pipette out the desired amount of resin into the stirring, 
chilled solution (approximately 1.5 to 2 g per pipette-full).
    2.3.4.4 Quickly reweigh the cup, resin, and pipette with the bulb.
    2.3.4.5 The resultant weight loss equals the grams of resin being 
tested.
    2.3.5 Rapidly titrate the solution with 0.1 N HCl to the colorless 
endpoint described in Step 3 (2.3.3).
    2.3.6 Repeat the test in triplicate.
    2.4 Calculation.
    2.4.1 The percent free-formaldehyde (%HCHO) is calculated as 
follows:
[GRAPHIC] [TIFF OMITTED] TR11AP02.024

    2.4.2 Compute the average percent free-formaldehyde of the three 
tests.
    (Note: If the results of the three tests are not within a range of 
0.5 percent or if the average of the three tests 
does not meet expected limits, carry out Part B and then repeat Part A.)

                       3.0 Part B--Standard Check

    Part B ensures that test reagents used in determining percent free-
formaldehyde in urea-formaldehyde resins are of proper concentration and 
that operator technique is correct. Should any doubts arise in either of 
these areas, the formaldehyde standard solution test should be carried 
out.
    3.1 Preparation and Standardization of a 1 Percent Formalin 
Solution.
    Prepare a solution containing approximately 1 percent formaldehyde 
from a stock 37 percent formalin solution. Standardize the prepared 
solution by titrating the hydroxyl ions resulting from the formation of 
the formaldehyde bisulfite complex.
    3.2 Apparatus Required.

    Note: All reagents must be American Chemical Society analytical 
reagent grade or better.

    3.2.1 One 1-liter (L) volumetric flask (class A).

    (Note: You must standardize this solution as described in section 
3.5. This solution is stable for 3 months.)
    3.4.2 Sodium Sulfite Solution 1.0 M (used for standardization of 
Formaldehyde Standard Solution). Quantitatively transfer, using 
distilled water as the transfer solvent, 31.50 g of anhydrous 
Na2SO3 into a 250-mL volumetric flask. Dissolve in 
approximately 100 mL of distilled water and fill to volume.
    (Note: You must prepare this solution daily, but the calibration of 
the Formaldehyde Standard Solution needs to be done only once.)
    3.4.3 Hydrochloric Acid Standard Solution 0.100 M. This reagent 
should be readily available as a primary standard that only needs to be 
diluted.
    3.5 Standardization.
    3.5.1 Standardization of Formaldehyde Standard Solution.
    3.5.1.1 Pipette 100.0 mL of 1 M sodium sulfite into a stirred 250-mL 
beaker.
    3.5.1.2 Using a standardized pH meter, measure and record the pH. 
The pH should be around 10. It is not essential the pH be 10; however, 
it is essential that the value be accurately recorded.
    3.5.1.3 To the stirring Na2SO3 solution, 
pipette in 10.0 mL of Formaldehyde Standard Solution. The pH should rise 
sharply to about 12.
    3.5.1.4 Using the pH meter as a continuous monitor, titrate the 
solution back to the original exact pH using 0.100 N HCl. Record the 
milliliters of HCl used as titrant. (Note: Approximately 30 to 35 mL of 
HCl will be required.)
    3.5.1.5 Calculate the concentration of the Formaldehyde Standard 
Solution using the equation as follows:
[GRAPHIC] [TIFF OMITTED] TR11AP02.025

    3.6 Procedure.
    3.6.1 Prepare a sufficient quantity of crushed ice for three 
determinations (two trays of cubes).
    3.6.2 Put 70 cc of 1 M Na2SO3 solution into a 
400-mL beaker. Begin stirring and add approximately 100 g of crushed ice 
and 2 g NaCl. Maintain 0 [deg]C during the test, adding ice as 
necessary.
    3.6.3 Add 10-15 drops of thymolphthalein indicator to the chilled 
solution. If the solution remains clear, add 0.1 N NaOH until the 
solution turns blue; then add 0.1 N HCl back to the colorless endpoint. 
If the solution turns blue upon adding the indicator, add 0.1 N HCl to 
the colorless endpoint.
    3.6.4 On the analytical balance, accurately weigh a sample of 
Formaldehyde Standard Solution as follows.
    3.6.4.1 Pour about 0.5 inches of Formaldehyde Standard Solution into 
a 5-oz. plastic cup.
    3.6.4.2 Determine the gross weight of the cup, Formaldehyde Standard 
Solution, and a disposable pipette fitted with a small rubber bulb.
    3.6.4.3 Pipette approximately 5 g of the Formaldehyde Standard 
Solution into the stirring, chilled Na2SO3 
solution.
    3.6.4.4 Quickly reweigh the cup, Formaldehyde Standard Solution, and 
pipette with the bulb.
    3.6.4.5 The resultant weight loss equals the grams of Formaldehyde 
Standard Solution being tested.
    3.6.5 Rapidly titrate the solution with 0.1 N HCl to the colorless 
endpoint in Step 3 (3.6.3).
    3.6.6 Repeat the test in triplicate.
    3.7 Calculation for Formaldehyde Standard Solution.
    3.7.1 The percent free-formaldehyde (% HCHO) is calculated as 
follows:
[GRAPHIC] [TIFF OMITTED] TR11AP02.026

    3.7.2 The range of the results of three tests should be no more than 
5 percent of the actual Formaldehyde Standard 
Solution concentration. Report results to two decimal places.

Sec. Appendix B to Subpart HHHH of Part 63--Method for the Determination 
                           of Loss-on-Ignition

                               1.0 Purpose

    The purpose of this test is to determine the loss-on-ignition (LOI) 
of wet-formed fiberglass mat.

                              2.0 Equipment

    2.1 Scale sensitive to 0.001 gram (g).
    2.2 Drying oven equipped with a means of constant temperature 
regulation and mechanical air convection.
    2.3 Furnace designed to heat to at least 625 [deg]C (1,157 [deg]F) 
and controllable to 25 [deg]C (45 [deg]F).
    2.4 Crucible, high form, 250 milliliter (mL).
    2.5 Desiccator.
    2.6 Pan balance (see Note 2 in 4.9)

                     3.0 Sample Collection Procedure

    3.1 Obtain a sample of mat in accordance with Technical Association 
of the Pulp and Paper Industry (TAPPI) method 1007 ``Sample Location.''
    3.2 Use a 5- to 10-g sample cut into pieces small enough to fit into 
the crucible.
    3.3 Place the sample in the crucible. (Note 1: To test without the 
use of a crucible, see Note 2 after Section 4.8.)
    3.4 Condition the sample in the furnace set at 105 3 [deg]C (221 9 [deg]F) for 5 
minutes 30 seconds.

                              4.0 Procedure

    4.1 Condition each sample by drying for 5 minutes 30 seconds at 105 3 [deg]C (22 
5 [deg]F).
    4.2 Remove the test sample from the furnace and cool in the 
desiccator for 30 minutes in the standard atmosphere for testing glass 
textiles.
    4.3 Place the empty crucible in the furnace at 625 25 [deg]C (1,157 45 [deg]F). After 
30 minutes, remove and cool the crucible in the standard atmosphere 
(TAPPI method 1008) for 30 minutes.
    4.4 Identify each crucible with respect to each test sample of mat.
    4.5 Weigh the empty crucible to the nearest 0.001 g. Record this 
weight as the tare mass, T.
    4.6 Place the test sample in the crucible and weigh to the nearest 
0.001 g. Record this weight as the initial mass, A.
    4.7 Place the test sample and crucible in the furnace and ignite at 
625 25 [deg]C (1,157 45 
[deg]F).
    4.8 After ignition for at least 30 minutes, remove the test sample 
and crucible from the furnace and cool in the desiccator for 30 minutes 
in the standard atmosphere (TAPPI method 1008).
    4.9 Remove each crucible, and test each sample separately from the 
desiccator, and immediately weigh each sample to the nearest 0.001 g. 
Record this weight as the ignited mass, B. (Note 2: When it is known 
that no ash residue separates from the test sample during the weighing 
and igniting processes, you may weigh the sample separately without the 
crucible. When this occurs, the tare mass (T) equals zero. With 
appropriate care, you can dry and weigh a single piece of mat and place 
with tongs into the ignition oven on appropriate refractory supports. 
When the ignition time is over, remove the sample as an intact fragile 
web and weigh it directly on a pan balance.)

                             5.0 Calculation

    5.1 Calculate the LOI for each sample as follows:
    [GRAPHIC] [TIFF OMITTED] TR11AP02.027
    
Where:

A = initial mass of crucible and sample before ignition (g);
B = mass of crucible and glass residue after ignition (g); and
T = tare mass of crucible, (g) (see Note 2).

    5.2 Report the percent LOI of the glass mat to the nearest 0.1 
percent.

                              6.0 Precision

    The repeatability of this test method for measurements on adjacent 
specimens from the same sample of mat is better than 1 percent.

all coatings and thinners, except for deadener materials and for 
adhesive and sealer materials that are not components of glass bonding 
systems, used in coating operations added to the affected source 
pursuant to Sec. 63.3082(c) to no more than 0.060 kg/liter (0.50 lb/
gal) of applied coating solids used during each month, determined 
according to the requirements in Sec. 63.3171.
    (c) You must limit average organic HAP emissions from all adhesive

    (1) Adhesive and sealer materials that are not components of glass 
bonding systems are subject to and must be included in your 
demonstration of compliance for paragraph (c) of this section.

[[Page 414]]

    (2) Deadener materials are subject to and must be included in your 
demonstration of compliance for paragraph (d) of this section.
    (3) All other coatings and thinners are subject to and must be 
included in your demonstration of compliance for paragraphs (a) or (b) 
of this section.
    (f) If your facility has multiple paint lines (e.g., two or more 
totally distinct paint lines each serving a distinct assembly line, or a 
facility with two or more paint lines sharing the same paint kitchen or 
mix room), then for the operations addressed in paragraphs (a) and (b) 
of this section:
    (1) You may choose to use a single grouping under paragraph (a) of 
this section for all of your electrodeposition primer, primer-surfacer, 
topcoat, final repair, glass bonding primer, and glass bonding adhesive 
operations.
    (2) You may choose to use a single grouping under paragraph (b) of 
this section for all of your primer-surfacer, topcoat, final repair, 
glass bonding primer, and glass bonding adhesive operations as long as 
each of your electrodeposition primer systems meets the operating limits 
of Sec. 63.3092(a) or (b).
    (3) You may choose to use one or more groupings under paragraph (a) 
of this section for the electrodeposition primer, primer-surfacer, 
topcoat, final repair, glass bonding primer, and glass bonding adhesive 
operations from one or more of your paint lines; and one or more 
groupings under paragraph (b) of this section for the primer-surfacer, 
topcoat, final repair, glass bonding primer, and glass bonding adhesive 
operations from the remainder of your paint lines, as long as each 
electrodeposition primer system associated with each paint line you 
include in a grouping under paragraph (b) of this section meets the 
operating limits of Sec. 63.3092(a) or (b). For example, if your 
facility has three paint lines, you may choose to use one grouping under 
paragraph (a) of this section for two of the paint lines; and a separate 
grouping under paragraph (b) of this section for the third paint line, 
as long as the electrodeposition primer system associated with the paint 
line you include in the grouping under paragraph (b) of this section 
meets the operating limits of Sec. 63.3092(a) or (b). Alternatively, 
you may choose to use one grouping for two of the paint lines and a 
separate grouping of the same type for the third paint line. Again, each 
electrodeposition primer system associated with each paint line you 
include in a grouping under paragraph (b) of this section must meet the 
operating limits of Sec. 63.3092(a) or (b).
    (4) You may choose to consider the electrodeposition primer, primer-
surfacer, topcoat, final repair, glass bonding primer, and glass bonding 
adhesive operations from each of your paint lines as a separate grouping 
under either paragraph (a) or paragraph (b) of this section. The 
electrodeposition primer system associated with each paint line you 
choose to consider in a grouping under paragraph (b) of this section 
must meet the operating limits of Sec. 63.3092(a) or (b). For example, 
if your facility has two paint lines, you may choose to use the grouping 
under paragraph (a) of this section for one paint line and the grouping 
under paragraph (b) of this section for the other paint line.

    (1) You may choose to use a single grouping under paragraph (a) of 
this section for all of your electrodeposition primer, primer-surfacer, 
topcoat, final repair, glass bonding primer, and glass bonding adhesive 
operations.
    (2) You may choose to use a single grouping under paragraph (b) of 
this section for all of your primer-surfacer, topcoat, final repair, 
glass bonding primer, and glass bonding adhesive operations, as long as 
each of your electrodeposition primer systems meets the operating limits 
of Sec. 63.3092(a) or (b).
    (3) You may choose to use one or more groupings under paragraph (a) 
of this section for the electrodeposition primer, primer-surfacer, 
topcoat, final repair, glass bonding primer, and glass bonding adhesive 
operations from one or more of your paint lines; and one or more 
groupings under paragraph (b) of this section for the primer-surfacer, 
topcoat, final repair, glass bonding primer, and glass bonding adhesive 
operations from the remainder of your paint lines, as long as each 
electrodeposition primer system associated with each paint line you 
include in a grouping under paragraph (b) of this section meets the 
operating limits of Sec. 63.3092(a) or (b). For example, if your 
facility has three paint lines, you may choose to use one grouping under 
paragraph (a) of this section for two of the paint lines and a separate 
grouping under paragraph (b) of this section for the third paint line, 
as long as the electrodeposition primer system associated with the paint 
line you include in the grouping under paragraph (b) of this section 
meets the operating limits of Sec. 63.3092(a) or (b). Alternatively, 
you may choose to use one grouping for two of the paint lines and a 
separate grouping of the same type for the third paint line. Again, each 
electrodeposition primer system associated with each paint line you 
include in a grouping under paragraph (b) of this section must meet the 
operating limits of Sec. 63.3092(a) or (b).

[[Page 416]]

    (4) You may choose to consider the electrodeposition primer, primer-
surfacer, topcoat, final repair, glass bonding primer, and glass bonding 
adhesive operations from each of your paint lines as a separate grouping 
under either paragraph (a) or paragraph (b) of this section. The 
electrodeposition primer system associated with each paint line you 
choose to consider in a grouping under paragraph (b) of this section 
must meet the operating limits of Sec. 63.3092(a) or (b). For example, 
if your facility has two paint lines, you may choose to use the grouping 
under paragraph (a) of this section for one paint line and the grouping 
under paragraph (b) of this section for the other paint line.



Sec. 63.3092  How must I control emissions from my electrodeposition
primer system if I want to comply with the combined primer-surfacer,
topcoat, final repair, glass bonding primer, and glass bonding adhesive 
          emission limit?

    If your electrodeposition primer system meets the requirements of 
either paragraph (a) or (b) of this section, you may choose to comply 
with the emission limits of Sec. 63.3090(b) or Sec. 63.3091(b) instead 
of the emission limits of Sec. 63.3090(a) or Sec. 63.3091(a).

controlled coating operation(s), you must meet the operating limits 
specified in Table 1 to this subpart. These operating limits apply to 
the emission capture and add-on control systems on the coating 
operation(s) for which you use this option, and you must establish the 
operating limits during the performance test according to the 
requirements in Sec. 63.3167. You must meet the operating limits at all 
times after you establish them.

from the emission limitations during the reporting period. If you used 
control devices to comply with the emission limits, and there were no 
periods during which the CPMS were out of control as specified in Sec. 
63.8(c)(7), the semiannual compliance report must include a statement 
that there were no periods during which the CPMS were out of control 
during the reporting period.
    (5) Deviations: adhesive, sealer, and deadener. If there was a 
deviation from the applicable emission limits in Sec. 63.3090(c) and

       Compliance Requirements for Adhesive, Sealer, and Deadener



Sec. 63.3150  By what date must I conduct the initial compliance
demonstration?

    You must complete the initial compliance demonstration for the 
initial compliance period according to the requirements of Sec. 
63.3151. The initial compliance period begins on the applicable 
compliance date specified in Sec. 63.3083 and ends on the last day of 
the month following the compliance date. If the compliance date occurs 
on any day other than the first day of a month, then the initial 
compliance period extends through the end of that month plus the next 
month. You must determine the mass average organic HAP content of the 
materials used each month for each group of materials for which an 
emission limitation is established in Sec. 63.3090(c) and (d) or Sec. 
63.3091(c) and (d). The initial compliance demonstration includes the 
calculations according to Sec. 63.3151 and supporting documentation 
showing that during the initial compliance period, the mass average 
organic HAP content for each group of materials was equal to or less 
than the applicable emission limits in Sec. 63.3090(c) and (d) or Sec. 
63.3091(c) and (d).

[[Page 427]]



Sec. 63.3151  How do I demonstrate initial compliance with the emission
limitations?

    You must separately calculate the mass average organic HAP content 
of the materials used during the initial compliance period for each 
group of materials for which an emission limit is established in Sec. 
63.3090(c) and (d) or Sec. 63.3091(c) and (d). If every individual 
material used within a group of materials meets the emission limit for 
that group of materials, you may demonstrate compliance with that 
emission limit by documenting the name and the organic HAP content of 
each material used during the initial compliance period. If any 
individual material used within a group of materials exceeds the 
emission limit for that group of materials, you must determine the mass 
average organic HAP content according to the procedures of paragraph (d) 
of this section.
    (a) Determine the mass fraction of organic HAP for each material 
used. You must determine the mass fraction of organic HAP for each 
material used during the compliance period by using one of the options 
in paragraphs (a)(1) through (5) of this section.
    (1) Method 311 (appendix A to 40 CFR part 63). You may use Method 
311 for determining the mass fraction of organic HAP. Use the procedures 
specified in paragraphs (a)(1)(i) and (ii) of this section when 
performing a Method 311 test.
    (i) Count each organic HAP that is measured to be present at 0.1 
percent by mass or more for OSHA-defined carcinogens, as specified in 29 
CFR 1910.1200(d)(4), and at 1.0 percent by mass or more for other 
compounds. For example, if toluene (not an OSHA carcinogen) is measured 
to be 0.5 percent of the material by mass, you do not have to count it. 
Express the mass fraction of each organic HAP you count as a value 
truncated to four places after the decimal point (e.g., 0.3791).
    (ii) Calculate the total mass fraction of organic HAP in the test 
material by adding up the individual organic HAP mass fractions and 
truncating the result to three places after the decimal point (e.g., 
0.7638 truncates to 0.763).
    (2) Method 24 (appendix A to 40 CFR part 60). For coatings, you may 
use Method 24 to determine the mass fraction of nonaqueous volatile 
matter and use that value as a substitute for mass fraction of organic 
HAP.
    (3) Alternative method. You may use an alternative test method for 
determining the mass fraction of organic HAP once the Administrator has 
approved it. You must follow the procedure in Sec. 63.7(f) to submit an 
alternative test method for approval.
    (4) Information from the supplier or manufacturer of the material. 
You may rely on information other than that generated by the test 
methods specified in paragraphs (a)(1) through (3) of this section, such 
as manufacturer's formulation data, if it represents each organic HAP 
that is present at 0.1 percent by mass or more for OSHA-defined 
carcinogens, as specified in 29 CFR 1910.1200(d)(4), and at 1.0 percent 
by mass or more for other compounds. For example, if toluene (not an 
OSHA carcinogen) is 0.5 percent of the material by mass, you do not have 
to count it. If there is a disagreement between such information and 
results of a test conducted according to paragraphs (a)(1) through (3) 
of this section, then the test method results will take precedence, 
unless after consultation, the facility demonstrates to the satisfaction 
of the enforcement authority that the facility's data are correct.
    (5) Solvent blends. Solvent blends may be listed as single 
components for some materials in data provided by manufacturers or 
suppliers. Solvent blends may contain organic HAP which must be counted 
toward the total organic HAP mass fraction of the materials. When 
neither test data nor manufacturer's data for solvent blends are 
available, you may use the default values for the mass fraction of 
organic HAP in the solvent blends listed in Table 3 or 4 to this 
subpart. If you use the tables, you must use the values in Table 3 for 
all solvent blends that match Table 3 entries, and you may only use 
Table 4 if the solvent blends in the materials you use do not match any 
of the solvent blends in Table 3 and you only know whether the blend is 
aliphatic or aromatic. However, if the results of a Method 311 test 
indicate higher values

[[Page 428]]

than those listed on Table 3 or 4 to this subpart, the Method 311 
results will take precedence, unless after consultation, the facility 
demonstrates to the satisfaction of the enforcement authority that the 
data from Table 3 or 4 are correct.
    (b) Determine the density of each material used. Determine the 
density of each material used during the compliance period from test 
results using ASTM Method D1475-98 (Reapproved 2003), ``Standard Test 
Method for Density of Liquid Coatings, Inks, and Related Products'' 
(incorporated by reference, see Sec. 63.14), or for powder coatings, 
test method A or test method B of ASTM Method D5965-02, ``Standard Test 
Methods for Specific Gravity of Coating Powders,'' (incorporated by 
reference, see Sec. 63.14), or information from the supplier or 
manufacturer of the material. If there is disagreement between ASTM 
Method D1475-98 (Reapproved 2003) test results or ASTM Method D5965-02, 
test method A or test method B test results and the supplier's or 
manufacturer's information, the test results will take precedence unless 
after consultation, the facility demonstrates to the satisfaction of the 
enforcement authority that the facility's data are correct.
    (c) Determine the volume of each material used. Determine the volume 
(liters) of each material used during each month by measurement or usage 
records.
    (d) Determine the mass average organic HAP content for each group of 
materials. Determine the mass average organic HAP content of the 
materials used during the initial compliance period for each group of 
materials for which an emission limit is established in Sec. 63.3090(c) 
and (d) or Sec. 63.3091(c) and (d), using Equations 1 and 2 of this 
section.
    (1) Calculate the mass average organic HAP content of adhesive and 
sealer materials other than components of the glass bonding system used 
in the initial compliance period using Equation 1 of this section:
[GRAPHIC] [TIFF OMITTED] TR26AP04.034

Where:

Cavg, as = Mass average organic HAP content of adhesives and 
          sealer materials used, kg/kg.

          per liter.
W as, j = Mass fraction of organic HAP in adhesive or sealer 
          material, j, kg/kg.
r = Number of adhesive and sealer materials used.

    (2) Calculate the mass average organic HAP content of deadener 
materials used in the initial compliance period using Equation 2 of this 
section:
[GRAPHIC] [TIFF OMITTED] TR26AP04.035

Where:

C avg, d = Mass average organic HAP content of deadener 
          material used, kg/kg.

[[Page 429]]

Vol d, m = Volume of deadener material, m, used, liters.
D d, m = Density of deadener material, m, used, kg per liter.
W d, m = Mass fraction of organic HAP in deadener material, 
          m, kg/kg.
s = Number of deadener materials used.

    (e) Compliance demonstration. The mass average organic HAP content 
for the compliance period must be less than or equal to the applicable 
emission limit in Sec. 63.3090(c) and (d) or Sec. 63.3091(c) and (d). 
You must keep all records as required by Sec. Sec. 63.3130 and 63.3131. 
As part of the Notification of Compliance Status required by Sec. 
63.3110, you must submit a statement that the coating operations were in

period because the mass average organic HAP content was less than or 
equal to the applicable emission limits in Sec. 63.3090(c) and (d) or 
Sec. 63.3091(c) and (d), determined according to this section.



Sec. 63.3152  How do I demonstrate continuous compliance with the
emission limitations?

    (a) To demonstrate continuous compliance, the mass average organic 
HAP content for each compliance period, determined according to Sec. 
63.3151(a) through (d), must be less than or equal to the applicable 
emission limit in Sec. 63.3090(c) and (d) or Sec. 63.3091(c) and (d). 
A compliance period consists of 1 month. Each month after the end of the 
initial compliance period described in Sec. 63.3150 is a compliance 
period consisting of that month.
    (b) If the mass average organic HAP emission content for any 
compliance period exceeds the applicable emission limit in Sec. 
63.3090(c) and (d) or Sec. 63.3091(c) and (d), this is a deviation from 
the emission limitations for that compliance period and must be reported 
as specified in Sec. Sec. 63.3110(c)(6) and 63.3120(a)(5).
    (c) You must maintain records as specified in Sec. Sec. 63.3130 and

coating. You must determine the volume fraction of coating solids (liter 
of coating solids per liter of coating) for each coating used during the 
compliance period by a test or by information provided by the supplier 
or the manufacturer of the material, as specified in paragraphs (f)(1) 
and (2) of this section. For electrodeposition primer operations, the 
volume fraction of solids must be determined for each material added to 
the tank or system during each month. If test results obtained according 
to paragraph (f)(1) of this section do not agree with the information 
obtained under paragraph (f)(2) of this section, the test results will 
take precedence unless, after consultation, the facility demonstrates to 
the satisfaction of the enforcement authority that the facility's data 
are correct.

Automobile and Light-Duty Truck Topcoat Operations,'' EPA-450/3-88-018 
(Docket ID No. OAR-2002-0093 and Docket ID No. A-2001-22). You may 
assume 100 percent transfer efficiency for electrodeposition primer 
coatings, glass bonding primers, and glass bonding adhesives. For final 
repair coatings, you may assume 40 percent transfer efficiency for air 
atomized spray and 55 percent transfer efficiency for electrostatic 
spray and high volume, low pressure spray. For blackout, chip resistant 
edge primer, interior color, in-line repair, lower body anti-chip 
coatings, or underbody anti-chip coatings, you may assume 40 percent 
transfer efficiency for air atomized spray, 55 percent transfer 
efficiency for electrostatic spray and high volume-low pressure spray, 
and 80 percent transfer efficiency for airless spray.

          liters.

period of startup, shutdown, or malfunction, from an operating limit or 
from any CPMS requirement for the capture system or control device 
serving the controlled coating operation occurred, during the month 
using Equation 2 of this section. The calculation of mass of organic HAP 
emission reduction for the controlled coating operation during the month 
applies the emission capture system efficiency and add-on control device 
efficiency to the mass of organic HAP contained in the coatings and 
thinners that are used in the coating operation served by the emission 
capture system and add-on control device during each month. Except as

which a deviation, including a deviation during a period of startup, 
shutdown, or malfunction, from an operating limit or from any CPMS 
requirement of the capture system or control device serving the 
controlled coating operation occurred, you must assume zero efficiency 
for the emission capture system and add-on control device. Equation 2 of

they were used on an uncontrolled coating operation for the time period 
of the deviation.

Sec. 63.3162  [Reserved]



Sec. 63.3163  How do I demonstrate continuous compliance with the
emission limitations?

    (a) To demonstrate continuous compliance with the applicable 
emission limit in Sec. 63.3090(a) or Sec. 63.3091(a), the organic HAP 
emission rate for each compliance period, determined according to the 
procedures in Sec. 63.3161, must be equal to or less than the 
applicable emission limit in Sec. 63.3090(a) or Sec. 63.3091(a). A 
compliance period consists of 1 month. Each month after the end of the 
initial compliance period described in Sec. 63.3160 is a compliance 
period consisting of that month. You must perform the calculations in 
Sec. 63.3161 on a monthly basis.
    (b) If the organic HAP emission rate for any 1 month compliance 
period exceeded the applicable emission limit in Sec. 63.3090(a) or 
Sec. 63.3091(a), this is a deviation from the emission limitation for 
that compliance period and must be reported as specified in Sec. Sec. 
63.3110(c)(6) and 63.3120(a)(6).
    (c) You must demonstrate continuous compliance with each operating 
limit required by Sec. 63.3093 that applies to you, as specified in 
Table 1 to this subpart.
    (1) If an operating parameter is out of the allowed range specified 
in Table 1 to this subpart, this is a deviation from the operating limit 
that must be reported as specified in Sec. Sec. 63.3110(c)(6) and 
63.3120(a)(6).
    (2) If an operating parameter deviates from the operating limit 
specified in Table 1 to this subpart, then you must assume that the 
emission capture system and add-on control device were achieving zero 
efficiency during the time period of the deviation except as provided in 
Sec. 63.3161(p).
    (d) You must meet the requirements for bypass lines in Sec. 
63.3168(b) for control devices other than solvent recovery systems for 
which you conduct liquid-liquid material balances. If any bypass line is 
opened and emissions are diverted to the atmosphere when the coating 
operation is running, this is a deviation that must be reported as 
specified in Sec. 63.3110(c)(6) and 63.3120(a)(6). For the purposes of 
completing the compliance calculations specified in Sec. 63.3161(k), 
you must assume that the emission capture system and add-on control 
device were achieving zero efficiency during the time period of the 
deviation.
    (e) You must demonstrate continuous compliance with the work 
practice standards in Sec. 63.3094. If you did not develop a work 
practice plan, if you did not implement the plan, or if you did not keep 
the records required by Sec. 63.3130(n), this is a deviation from the 
work practice standards that must be reported as specified in Sec. Sec. 
63.3110(c)(6) and 63.3120(a)(6).

[[Page 440]]

    (f) If there were no deviations from the emission limitations, 
submit a statement as part of the semiannual compliance report that you 
were in compliance with the emission limitations during the reporting 
period because the organic HAP emission rate for each compliance period 
was less than or equal to the applicable emission limit in Sec. 
63.3090(a) or Sec. 63.3091(a), and you achieved the operating limits 
required by Sec. 63.3093 and the work practice standards required by 
Sec. 63.3094 during each compliance period.
    (g) [Reserved]
    (h) Consistent with Sec. Sec. 63.6(e) and 63.7(e)(1), deviations 
that occur during a period of startup, shutdown, or malfunction of the 
emission capture system, add-on control device, or coating operation 
that may affect emission capture or control device efficiency are not 
violations if you demonstrate to the Administrator's satisfaction that 
you were operating in accordance with Sec. 63.6(e)(1). The 
Administrator will determine whether deviations that occur during a 
period you identify as a startup, shutdown, or malfunction are 
violations according to the provisions in Sec. 63.6(e).
    (i) [Reserved]
    (j) You must maintain records as specified in Sec. Sec. 63.3130 and 
63.3131.

[69 FR 22623, Apr. 26, 2004, as amended at 71 FR 20464, Apr. 20, 2006]



Sec. 63.3164  What are the general requirements for performance tests?

    (a) You must conduct each performance test required by Sec. 63.3160 
according to the requirements in Sec. 63.7(e)(1) and under the 
conditions in this section unless you obtain a waiver of the performance 
test according to the provisions in Sec. 63.7(h).
    (1) Representative coating operation operating conditions. You must 
conduct the performance test under representative operating conditions 
for the coating operation. Operations during periods of startup, 
shutdown, or malfunction, and during periods of nonoperation do not 
constitute representative conditions. You must record the process 
information that is necessary to document operating conditions during 
the test and explain why the conditions represent normal operation.
    (2) Representative emission capture system and add-on control device 
operating conditions. You must conduct the performance test when the 
emission capture system and add-on control device are operating at a 
representative flow rate, and the add-on control device is operating at 
a representative inlet concentration. You must record information that 
is necessary to document emission capture system and add-on control 
device operating conditions during the test and explain why the 
conditions represent normal operation.
    (b) You must conduct each performance test of an emission capture 
system according to the requirements in Sec. 63.3165. You must conduct 
each performance test of an add-on control device according to the 
requirements in Sec. 63.3166.



Sec. 63.3165  How do I determine the emission capture system efficiency?

    You must use the procedures and test methods in this section to 
determine capture efficiency as part of the performance test required by 
Sec. 63.3160. For purposes of this subpart, a spray booth air seal is 
not considered a natural draft opening in a PTE or a temporary total 
enclosure provided you demonstrate that the direction of air movement 
across the interface between the spray booth air seal and the spray 
booth is into the spray booth. For purposes of this subpart, a bake oven 
air seal is not considered a natural draft opening in a PTE or a 
temporary total enclosure provided you demonstrate that the direction of 
air movement across the interface between the bake oven air seal and the 
bake oven is into the bake oven. You may use lightweight strips of 
fabric or paper, or smoke tubes to make such demonstrations as part of 
showing that your capture system is a PTE or conducting a capture 
efficiency test using a temporary total enclosure. You cannot count air 
flowing from a spray booth air seal into a spray booth as air flowing 
through a natural draft opening into a PTE or into a temporary total 
enclosure unless you elect to treat that spray booth air seal as a 
natural draft opening. You cannot count air flowing from a bake oven air 
seal into a bake oven as air flowing through a natural

[[Page 441]]

draft opening into a PTE or into a temporary total enclosure unless you 
elect to treat that bake oven air seal as a natural draft opening.
    (a) Assuming 100 percent capture efficiency. You may assume the 
capture system efficiency is 100 percent if both of the conditions in 
paragraphs (a)(1) and (2) of this section are met:
    (1) The capture system meets the criteria in Method 204 of appendix 
M to 40 CFR part 51 for a PTE and directs all the exhaust gases from the 
enclosure to an add-on control device.
    (2) All coatings and thinners used in the coating operation are 
applied within the capture system, and coating solvent flash-off and 
coating curing and drying occurs within the capture system. For example, 
this criterion is not met if parts enter the open shop environment when 
being moved between a spray booth and a curing oven.
    (b) Measuring capture efficiency. If the capture system does not 
meet both of the criteria in paragraphs (a)(1) and (2) of this section, 
then you must use one of the five procedures described in paragraphs (c) 
through (g) of this section to measure capture efficiency. The capture 
efficiency measurements use TVH capture efficiency as a surrogate for 
organic HAP capture efficiency. For the protocols in paragraphs (c) and 
(d) of this section, the capture efficiency measurement must consist of 
three test runs. Each test run must be at least 3 hours duration or the 
length of a production run, whichever is longer, up to 8 hours. For the 
purposes of this test, a production run means the time required for a 
single part to go from the beginning to the end of production, which 
includes surface preparation activities and drying or curing time.
    (c) Liquid-to-uncaptured-gas protocol using a temporary total 
enclosure or building enclosure. The liquid-to-uncaptured-gas protocol 
compares the mass of liquid TVH in materials used in the coating 
operation to the mass of TVH emissions not captured by the emission 
capture system. Use a temporary total enclosure or a building enclosure 
and the procedures in paragraphs (c)(1) through (6) of this section to 
measure emission capture system efficiency using the liquid-to-
uncaptured-gas protocol.
    (1) Either use a building enclosure or construct an enclosure around 
the coating operation where coatings and thinners are applied, and all 
areas where emissions from these applied coatings and thinners 
subsequently occur, such as flash-off, curing, and drying areas. The 
areas of the coating operation where capture devices collect emissions 
for routing to an add-on control device, such as the entrance and exit 
areas of an oven or spray booth, must also be inside the enclosure. The 
enclosure must meet the applicable definition of a temporary total 
enclosure or building enclosure in Method 204 of appendix M to 40 CFR 
part 51.
    (2) Use Method 204A or F of appendix M to 40 CFR part 51 to 
determine the mass fraction of TVH liquid input from each coating and 
thinner used in the coating operation during each capture efficiency 
test run. To make the determination, substitute TVH for each occurrence 
of the term volatile organic compounds (VOC) in the methods.
    (3) Use Equation 1 of this section to calculate the total mass of 
TVH liquid input from all the coatings and thinners used in the coating 
operation during each capture efficiency test run.
[GRAPHIC] [TIFF OMITTED] TR26AP04.018

Where:

TVHi = Mass fraction of TVH in coating or thinner, i, used in 
          the coating operation during the capture efficiency test run, 
          kg TVH per kg material.
Voli = Total volume of coating or thinner, i, used in the 
          coating operation during the capture efficiency test run, 
          liters.
Di = Density of coating or thinner, i, kg material per liter 
          material.

[[Page 442]]

n = Number of different coatings and thinners used in the coating 
          operation during the capture efficiency test run.

    (4) Use Method 204D or E of appendix M to 40 CFR part 51 to measure 
the total mass, kg, of TVH emissions that are not captured by the 
emission capture system; they are measured as they exit the temporary 
total enclosure or building enclosure during each capture efficiency 
test run. To make the measurement, substitute TVH for each occurrence of 
the term VOC in the methods.
    (i) Use Method 204D if the enclosure is a temporary total enclosure.
    (ii) Use Method 204E if the enclosure is a building enclosure. 
During the capture efficiency measurement, all organic compound emitting 
operations inside the building enclosure, other than the coating 
operation for which capture efficiency is being determined, must be shut 
down, but all fans and blowers must be operating normally.
    (5) For each capture efficiency test run, determine the percent 
capture efficiency of the emission capture system using Equation 2 of 
this section:
[GRAPHIC] [TIFF OMITTED] TR26AP04.019

Where:

CE = Capture efficiency of the emission capture system vented to the 
          add-on control device, percent.
TVH used = Total mass of TVH liquid input used in the coating 
          operation during the capture efficiency test run, kg.
TVH uncaptured = Total mass of TVH that is not captured by 
          the emission capture system and that exits from the temporary 
          total enclosure or building enclosure during the capture 
          efficiency test run, kg.

    (6) Determine the capture efficiency of the emission capture system 
as the average of the capture efficiencies measured in the three test 
runs.
    (d) Gas-to-gas protocol using a temporary total enclosure or a 
building enclosure. The gas-to-gas protocol compares the mass of TVH 
emissions captured by the emission capture system to the mass of TVH 
emissions not captured. Use a temporary total enclosure or a building 
enclosure and the procedures in paragraphs (d)(1) through (5) of this 
section to measure emission capture system efficiency using the gas-to-
gas protocol.
    (1) Either use a building enclosure or construct an enclosure around 
the coating operation where coatings and thinners are applied, and all 
areas where emissions from these applied coatings and thinners 
subsequently occur, such as flash-off, curing, and drying areas. The 
areas of the coating operation where capture devices collect emissions 
generated by the coating operation for routing to an add-on control 
device, such as the entrance and exit areas of an oven or a spray booth, 
must also be inside the enclosure. The enclosure must meet the 
applicable definition of a temporary total enclosure or building 
enclosure in Method 204 of appendix M to 40 CFR part 51.
    (2) Use Method 204B or C of appendix M to 40 CFR part 51 to measure 
the total mass, kg, of TVH emissions captured by the emission capture 
system during each capture efficiency test run as measured at the inlet 
to the add-on control device. To make the measurement, substitute TVH 
for each occurrence of the term VOC in the methods.
    (i) The sampling points for the Method 204B or C measurement must be 
upstream from the add-on control device and must represent total 
emissions routed from the capture system and entering the add-on control 
device.
    (ii) If multiple emission streams from the capture system enter the 
add-on control device without a single common duct, then the emissions 
entering the add-on control device must be simultaneously or 
sequentially measured in each duct, and the total emissions entering the 
add-on control device must be determined.
    (3) Use Method 204D or E of appendix M to 40 CFR part 51 to measure 
the total mass, kg, of TVH emissions that

[[Page 443]]

are not captured by the emission capture system; they are measured as 
they exit the temporary total enclosure or building enclosure during 
each capture efficiency test run. To make the measurement, substitute 
TVH for each occurrence of the term VOC in the methods.
    (i) Use Method 204D if the enclosure is a temporary total enclosure.
    (ii) Use Method 204E if the enclosure is a building enclosure. 
During the capture efficiency measurement, all organic compound emitting 
operations inside the building enclosure, other than the coating 
operation for which capture efficiency is being determined, must be shut 
down, but all fans and blowers must be operating normally.
    (4) For each capture efficiency test run, determine the percent 
capture efficiency of the emission capture system using Equation 3 of 
this section:
[GRAPHIC] [TIFF OMITTED] TR26AP04.020

Where:

CE = Capture efficiency of the emission capture system vented to the 
          add-on control device, percent.
TVHcaptured = Total mass of TVH captured by the emission 
          capture system as measured at the inlet to the add-on control 
          device during the emission capture efficiency test run, kg.
TVHuncaptured = Total mass of TVH that is not captured by the 
          emission capture system and that exits from the temporary 
          total enclosure or building enclosure during the capture 
          efficiency test run, kg.

    (5) Determine the capture efficiency of the emission capture system 
as the average of the capture efficiencies measured in the three test 
runs.
    (e) Panel testing to determine the capture efficiency of flash-off 
or bake oven emissions. You may conduct panel testing to determine the 
capture efficiency of flash-off or bake oven emissions using ASTM Method 
D5087-02, ``Standard Test Method for Determining Amount of Volatile 
Organic Compound (VOC) Released from Solventborne Automotive Coatings 
and Available for Removal in a VOC Control Device (Abatement)'' 
(incorporated by reference, see Sec. 63.14), ASTM Method D6266-00a, 
``Test Method for Determining the Amount of Volatile Organic Compound 
(VOC) Released from Waterborne Automotive Coatings and Available for 
Removal in a VOC Control Device (Abatement)'' (incorporated by

for Determining Daily Volatile Organic Compound Emission Rate of 
Automobile and Light-Duty Truck Topcoat Operations,'' EPA-450/3-88-018 
(Docket ID No. OAR-2002-0093 and Docket ID No. A-2001-22). You may 
conduct panel testing on representative coatings as described in 
``Protocol for Determining Daily Volatile Organic Compound Emission Rate 
of Automobile and Light-Duty Truck Topcoat Operations,'' EPA-450/3-88-
018 (Docket ID No. OAR-2002-0093 and Docket ID No. A-2001-22). The 
results of these panel testing procedures are in units of mass of VOC 
per volume of coating solids deposited and must be converted to a 
percent value for use in this subpart. If you panel test representative 
coatings, then you may convert the panel test result for each 
representative coating either to a unique percent capture efficiency for 
each coating grouped with that representative coating by using coating 
specific values for the volume of coating solids deposited per volume of 
coating used, mass of VOC per volume of coating, volume fraction solids, 
transfer efficiency, density and mass fraction VOC in Equations 4 
through 6 of this section; or to a composite percent capture efficiency 
for the group of coatings by using composite values for the group of 
coatings for the volume of coating solids deposited per volume of 
coating used and for the mass of VOC per volume of coating, and average 
values for the group of coatings for volume fraction solids, transfer 
efficiency, density and mass fraction VOC in

alternative for using panel test results expressed in units of mass of 
VOC per mass of coating solids deposited is presented in paragraph

Sec. 63.3166  How do I determine the add-on control device emission
destruction or removal efficiency?

    You must use the procedures and test methods in this section to 
determine the add-on control device emission destruction or removal 
efficiency as part of the performance test required by Sec. 63.3160. 
You must conduct three test runs as specified in Sec. 63.7(e)(3), and 
each test run must last at least 1 hour.
    (a) For all types of add-on control devices, use the test methods 
specified in paragraphs (a)(1) through (5) of this section.
    (1) Use Method 1 or 1A of appendix A to 40 CFR part 60, as 
appropriate, to select sampling sites and velocity traverse points.
    (2) Use Method 2, 2A, 2C, 2D, 2F, or 2G of appendix A to 40 CFR part 
60, as appropriate, to measure gas volumetric flow rate.
    (3) Use Method 3, 3A, or 3B of appendix A to 40 CFR part 60, as 
appropriate, for gas analysis to determine dry molecular weight. The 
ANSI/ASME PTC 19.10-1981, ``Flue and Exhaust Gas Analyses [Part 10, 
Instruments and Apparatus]'' (incorporated by reference, see Sec. 
63.14), may be used as an alternative to Method 3B.
    (4) Use Method 4 of appendix A to 40 CFR part 60 to determine stack 
gas moisture.
    (5) Methods for determining gas volumetric flow rate, dry molecular 
weight, and stack gas moisture must be performed, as applicable, during 
each test run.
    (b) Measure total gaseous organic mass emissions as carbon at the 
inlet and outlet of the add-on control device simultaneously, using 
either Method 25 or 25A of appendix A to 40 CFR part 60, as specified in 
paragraphs (b)(1) through (3) of this section. You must use the same 
method for both the inlet and outlet measurements.
    (1) Use Method 25 if the add-on control device is an oxidizer and 
you expect the total gaseous organic concentration as carbon to be more 
than 50 parts per million by volume (ppmv) at the control device outlet.
    (2) Use Method 25A if the add-on control device is an oxidizer and 
you expect the total gaseous organic concentration as carbon to be 50 
ppmv or less at the control device outlet.
    (3) Use Method 25A if the add-control device is not an oxidizer.
    (c) If two or more add-on control devices are used for the same 
emission stream, then you must measure emissions at the outlet of each 
device. For example, if one add-on control device is a concentrator with 
an outlet for the high-volume, dilute stream that has been treated by 
the concentrator, and a

[[Page 447]]

second add-on control device is an oxidizer with an outlet for the low-
volume, concentrated stream that is treated with the oxidizer, you must 
measure emissions at the outlet of the oxidizer and the high volume 
dilute stream outlet of the concentrator.
    (d) For each test run, determine the total gaseous organic emissions 
mass flow rates for the inlet and the outlet of the add-on control 
device, using Equation 1 of this section. If there is more than one 
inlet or outlet to the add-on control device, you must calculate the 
total gaseous organic mass flow rate using Equation 1 of this section 
for each inlet and each outlet and then total all of the inlet emissions 
and total all of the outlet emissions.
[GRAPHIC] [TIFF OMITTED] TR26AP04.026

Where:

Mf = Total gaseous organic emissions mass flow rate, kg per 
          hour (kg/h).
Cc = Concentration of organic compounds as carbon in the vent 
          gas, as determined by Method 25 or Method 25A, ppmv, dry 
          basis.
Qsd = Volumetric flow rate of gases entering or exiting the 
          add-on control device, as determined by Method 2, 2A, 2C, 2D, 
          2F, or 2G, dry standard cubic meters per hour (dscm/h).
0.0416 = Conversion factor for molar volume, kg-moles per cubic meter 
          (mol/m\3\) (@ 293 Kelvin (K) and 760 millimeters of mercury 
          (mmHg)).

    (e) For each test run, determine the add-on control device organic 
emissions destruction or removal efficiency using Equation 2 of this 
section:
[GRAPHIC] [TIFF OMITTED] TR26AP04.027

Where:

DRE = Organic emissions destruction or removal efficiency of the add-on 
          control device, percent.
Mfi = Total gaseous organic emissions mass flow rate at the 
          inlet(s) to the add-on control device, using Equation 1 of 
          this section, kg/h.
Mfo = Total gaseous organic emissions mass flow rate at the 
          outlet(s) of the add-on control device, using Equation 1 of 
          this section, kg/h.

    (f) Determine the emission destruction or removal efficiency of the 
add-on control device as the average of the efficiencies determined in 
the three test runs and calculated in Equation 2 of this section.



Sec. 63.3167  How do I establish the add-on control device operating
limits during the performance test?

    During the performance test required by Sec. 63.3160 and described 
in Sec. Sec. 63.3164 and 63.3166, you must establish the operating 
limits required by Sec. 63.3093 according to this section, unless you 
have received approval for alternative monitoring and operating limits 
under Sec. 63.8(f) as specified in Sec. 63.3093.
    (a) Thermal oxidizers. If your add-on control device is a thermal 
oxidizer, establish the operating limit according to paragraphs (a)(1) 
through (3) of this section.
    (1) During the performance test, you must monitor and record the 
combustion temperature at least once every 15 minutes during each of the 
three test runs. You must monitor the temperature in the firebox of the 
thermal oxidizer or immediately downstream of the firebox before any 
substantial heat exchange occurs.
    (2) Use all valid data collected during the performance test to 
calculate and record the average combustion temperature maintained 
during the performance test. This average combustion temperature is the 
minimum 3-hour average operating limit for your thermal oxidizer.
    (3) As an alternative, if the latest operating permit issued before 
April 26, 2007, for the thermal oxidizer at your facility contains 
recordkeeping and reporting requirements for the combustion temperature 
that are consistent with the requirements for thermal oxidizers in 40 
CFR 60.395(c), then you may set the minimum operating limit for the 
combustion temperature for each such thermal oxidizer at your affected 
source at 28 degrees Celsius (50 degrees Fahrenheit) below the average 
combustion temperature during the performance test of that thermal 
oxidizer. If you do not have an operating permit for the thermal 
oxidizer at your facility and the latest construction permit issued 
before April 26, 2007, for the thermal oxidizer at your facility 
contains recordkeeping and reporting

[[Page 448]]

requirements for the combustion temperature that are consistent with the 
requirements for thermal oxidizers in 40 CFR 60.395(c), then you may set 
the minimum operating limit for the combustion temperature for each such 
thermal oxidizer at your affected source at 28 degrees Celsius (50 
degrees Fahrenheit) below the average combustion temperature during the 
performance test of that thermal oxidizer. If you use 28 degrees Celsius 
(50 degrees Fahrenheit) below the combustion temperature maintained 
during the performance test as the minimum operating limit for a thermal 
oxidizer, then you must keep the combustion temperature set point on 
that thermal oxidizer no lower than 14 degrees Celsius (25 degrees 
Fahrenheit) below the lower of that set point during the performance 
test for that thermal oxidizer and the average combustion temperature 
maintained during the performance test for that thermal oxidizer.
    (b) Catalytic oxidizers. If your add-on control device is a 
catalytic oxidizer, establish the operating limits according to either 
paragraphs (b)(1) through (3) or paragraphs (b)(4) through (6) of this 
section.
    (1) During the performance test, you must monitor and record the 
temperature just before the catalyst bed and the temperature difference 
across the catalyst bed at least once every 15 minutes during each of 
the three test runs.
    (2) Use all valid data collected during the performance test to 
calculate and record the average temperature just before the catalyst 
bed and the average temperature difference across the catalyst bed 
maintained during the performance test. The minimum 3-hour average 
operating limits for your catalytic oxidizer are the average temperature 
just before the catalyst bed maintained during the performance test of 
that catalytic oxidizer and 80 percent of the average temperature 
difference across the catalyst bed maintained during the performance 
test of that catalytic oxidizer, except during periods of low 
production, the latter minimum operating limit is to maintain a positive 
temperature gradient across the catalyst bed. A low production period is 
when production is less than 80 percent of production rate during the 
performance test of that catalytic oxidizer.
    (3) As an alternative, if the latest operating permit issued before 
April 26, 2007, for the catalytic oxidizer at your facility contains 
recordkeeping and reporting requirements for the temperature before the 
catalyst bed that are consistent with the requirements for catalytic 
oxidizers in 40 CFR 60.395(c), then you may set the minimum operating 
limits for each such catalytic oxidizer at your affected source at 28 
degrees Celsius (50 degrees Fahrenheit) below the average temperature 
just before the catalyst bed maintained during the performance test for 
that catalytic oxidizer and 80 percent of the average temperature 
difference across the catalyst bed maintained during the performance 
test for that catalytic oxidizer, except during periods of low 
production the latter minimum operating limit is to maintain a positive 
temperature gradient across the catalyst bed. If you do not have an 
operating permit for the catalytic oxidizer at your facility and the 
latest construction permit issued before April 26, 2007, for the 
catalytic oxidizer at your facility contains recordkeeping and reporting 
requirements for the temperature before the catalyst bed that are 
consistent with the requirements for catalytic oxidizers in 40 CFR 
60.395(c), then you may set the minimum operating limits for each such 
catalytic oxidizer at your affected source at 28 degrees Celsius (50 
degrees Fahrenheit) below the average temperature just before the 
catalyst bed maintained during the performance test for that catalytic 
oxidizer and 80 percent of the average temperature difference across the 
catalyst bed maintained during the performance test for that catalytic 
oxidizer, except during periods of low production the latter minimum 
operating limit is to maintain a positive temperature gradient across 
the catalyst bed. A low production period is when production is less 
than 80 percent of production rate during the performance test. If you 
use 28 degrees Celsius (50 degrees Fahrenheit) below the average 
temperature just before the catalyst bed maintained during the 
performance test as the minimum operating limits for a catalytic 
oxidizer,

[[Page 449]]

then you must keep the set point for the temperature just before the 
catalyst bed on that catalytic oxidizer no lower than 14 degrees Celsius 
(25 degrees Fahrenheit) below the lower of that set point during the 
performance test for that catalytic oxidizer and the average temperature 
just before the catalyst bed maintained during the performance test for 
that catalytic oxidizer.
    (4) As an alternative to monitoring the temperature difference 
across the catalyst bed, you may monitor the temperature at the inlet to 
the catalyst bed and implement a site-specific inspection and 
maintenance plan for your catalytic oxidizer as specified in paragraph 
(b)(6) of this section. During the performance test, you must monitor 
and record the temperature just before the catalyst bed at least once 
every 15 minutes during each of the three test runs. Use all valid data 
collected during the performance test to calculate and record the 
average temperature just before the catalyst bed during the performance 
test. This is the minimum operating limit for your catalytic oxidizer.
    (5) If the latest operating permit issued before April 26, 2007, for 
the catalytic oxidizer at your facility contains recordkeeping and 
reporting requirements for the temperature before the catalyst bed that 
are consistent with the requirements for catalytic oxidizers in 40 CFR 
60.395(c), then you may set the minimum operating limit for each such 
catalytic oxidizer at your affected source at 28 degrees Celsius (50 
degrees Fahrenheit) below the average temperature just before the 
catalyst bed maintained during the performance test for that catalytic 
oxidizer. If you do not have an operating permit for the catalytic 
oxidizer at your facility and the latest construction permit issued 
before April 26, 2007, for the catalytic oxidizer at your facility 
contains recordkeeping and reporting requirements for the temperature 
before the catalyst bed that are consistent with the requirements for 
catalytic oxidizers in 40 CFR 60.395(c), then you may set the minimum 
operating limit for each such catalytic oxidizer at your affected source 
at 28 degrees Celsius (50 degrees Fahrenheit) below the average 
temperature just before the catalyst bed maintained during the 
performance test for that catalytic oxidizer. If you use 28 degrees 
Celsius (50 degrees Fahrenheit) below the average temperature just 
before the catalyst bed maintained during the performance test as the 
minimum operating limit for a catalytic oxidizer, then you must keep the 
set point for the temperature just before the catalyst bed on that 
catalytic oxidizer no lower than 14 degrees Celsius (25 degrees 
Fahrenheit) below the lower of that set point during the performance 
test for that catalytic oxidizer and the average temperature just before 
the catalyst bed maintained during the performance test for that 
catalytic oxidizer.
    (6) You must develop and implement an inspection and maintenance 
plan for your catalytic oxidizer(s) for which you elect to monitor 
according to paragraph (b)(4) or (b)(5) of this section. The plan must 
address, at a minimum, the elements specified in paragraphs (b)(6)(i) 
through (iii) of this section.
    (i) Annual sampling and analysis of the catalyst activity (i.e., 
conversion efficiency) following the manufacturer's or catalyst 
supplier's recommended procedures. If problems are found during the 
catalyst activity test, you must replace the catalyst bed or take other 
corrective action consistent with the manufacturer's recommendations.
    (ii) Monthly external inspection of the catalytic oxidizer system, 
including the burner assembly and fuel supply lines for problems and, as 
necessary, adjust the equipment to assure proper air-to-fuel mixtures.
    (iii) Annual internal inspection of the catalyst bed to check for 
channeling, abrasion, and settling. If problems are found during the 
annual internal inspection of the catalyst, you must replace the 
catalyst bed or take other corrective action consistent with the 
manufacturer's recommendations. If the catalyst bed is replaced and is 
not of like or better kind and quality as the old catalyst, then you 
must conduct a new performance test to determine destruction efficiency 
according to Sec. 63.3166. If a catalyst bed is replaced and the 
replacement catalyst is of like or better kind and quality as the old

[[Page 450]]

catalyst, then a new performance test to determine destruction 
efficiency is not required and you may continue to use the previously 
established operating limits for that catalytic oxidizer.
    (c) Regenerative carbon adsorbers. If your add-on control device is 
a regenerative carbon adsorber, establish the operating limits according 
to paragraphs (c)(1) and (2) of this section.
    (1) You must monitor and record the total regeneration desorbing gas 
(e.g., steam or nitrogen) mass flow for each regeneration cycle and the 
carbon bed temperature after each carbon bed regeneration and cooling 
cycle for the regeneration cycle either immediately preceding or 
immediately following the performance test.
    (2) The operating limits for your carbon adsorber are the minimum 
total desorbing gas mass flow recorded during the regeneration cycle and 
the maximum carbon bed temperature recorded after the cooling cycle.
    (d) Condensers. If your add-on control device is a condenser, 
establish the operating limits according to paragraphs (d)(1) and (2) of 
this section.
    (1) During the performance test, you must monitor and record the 
condenser outlet (product side) gas temperature at least once every 15 
minutes during each of the three test runs.
    (2) Use all valid data collected during the performance test to 
calculate and record the average condenser outlet (product side) gas 
temperature maintained during the performance test. This average 
condenser outlet gas temperature is the maximum 3-hour average operating 
limit for your condenser.
    (e) Concentrators. If your add-on control device includes a 
concentrator, you must establish operating limits for the concentrator 
according to paragraphs (e)(1) and (2)of this section.
    (1) During the performance test, you must monitor and record the 
desorption gas inlet temperature at least once every 15 minutes during 
each of the three runs of the performance test.
    (2) Use all valid data collected during the performance test to 
calculate and record the average desorption gas inlet temperature. The 
minimum operating limit for the concentrator is 8 degrees Celsius (15 
degrees Fahrenheit) below the average desorption gas inlet temperature 
maintained during the performance test for that concentrator. You must 
keep the set point for the desorption gas inlet temperature no lower 
than 6 degrees Celsius (10 degrees Fahrenheit) below the lower of that 
set point during the performance test for that concentrator and the 
average desorption gas inlet temperature maintained during the 
performance test for that concentrator.
    (f) Emission capture systems. For each capture device that is not 
part of a PTE that meets the criteria of Sec. 63.3165(a) and that is 
not capturing emissions from a downdraft spray booth or from a flash-off 
area or bake oven associated with a downdraft spray booth, establish an 
operating limit for either the gas volumetric flow rate or duct static 
pressure, as specified in paragraphs (f)(1) and (2) of this section. The 
operating limit for a PTE is specified in Table 1 to this subpart.
    (1) During the capture efficiency determination required by Sec. 
63.3160 and described in Sec. Sec. 63.3164 and 63.3165, you must 
monitor and record either the gas volumetric flow rate or the duct 
static pressure for each separate capture device in your emission 
capture system at least once every 15 minutes during each of the three 
test runs at a point in the duct between the capture device and the add-
on control device inlet.
    (2) Calculate and record the average gas volumetric flow rate or 
duct static pressure for the three test runs for each capture device, 
using all valid data. This average gas volumetric flow rate or duct 
static pressure is the minimum operating limit for that specific capture 
device.

Sec. 63.3168  What are the requirements for continuous parameter
monitoring system installation, operation, and maintenance?

    (a) General. You must install, operate, and maintain each CPMS 
specified in paragraphs (c), (e), (f), and (g) of this section according 
to paragraphs (a)(1) through (6) of this section. You must install, 
operate, and maintain each CPMS specified in paragraphs (b) and

[[Page 451]]

(d) of this section according to paragraphs (a)(3) through (5) of this 
section.
    (1) The CPMS must complete a minimum of one cycle of operation for 
each successive 15-minute period. You must have a minimum of four 
equally-spaced successive cycles of CPMS operation in 1 hour.
    (2) You must determine the average of all recorded readings for each 
successive 3-hour period of the emission capture system and add-on 
control device operation.
    (3) You must record the results of each inspection, calibration, and 
validation check of the CPMS.
    (4) You must maintain the CPMS at all times and have available 
necessary parts for routine repairs of the monitoring equipment.
    (5) You must operate the CPMS and collect emission capture system 
and add-on control device parameter data at all times that a controlled 
coating operation is operating, except during monitoring malfunctions, 
associated repairs, and required quality assurance or control activities 
(including, if applicable, calibration checks and required zero and span 
adjustments).
    (6) You must not use emission capture system or add-on control 
device parameter data recorded during monitoring malfunctions, 
associated repairs, out-of-control periods, or required quality 
assurance or control activities when calculating data averages. You must 
use all the data collected during all other periods in calculating the 
data averages for determining compliance with the emission capture 
system and add-on control device operating limits.
    (7) A monitoring malfunction is any sudden, infrequent, not 
reasonably preventable failure of the CPMS to provide valid data. 
Monitoring failures that are caused in part by poor maintenance or 
careless operation are not malfunctions. Any period for which the 
monitoring system is out of control and data are not available for 
required calculations is a deviation from the monitoring requirements.
    (b) Capture system bypass line. You must meet the requirements of 
paragraphs (b)(1) and (2) of this section for each emission capture 
system that contains bypass lines that could divert emissions away from 
the add-on control device to the atmosphere.
    (1) You must monitor or secure the valve or closure mechanism 
controlling the bypass line in a nondiverting position in such a way 
that the valve or closure mechanism cannot be opened without creating a 
record that the valve was opened. The method used to monitor or secure 
the valve or closure mechanism must meet one of the requirements 
specified in paragraphs (b)(1)(i) through (iv) of this section.
    (i) Flow control position indicator. Install, calibrate, maintain, 
and operate according to the manufacturer's specifications a flow 
control position indicator that takes a reading at least once every 15 
minutes and provides a record indicating whether the emissions are 
directed to the add-on control device or diverted from the add-on 
control device. The time of occurrence and flow control position must be 
recorded, as well as every time the flow direction is changed. The flow 
control position indicator must be installed at the entrance to any 
bypass line that could divert the emissions away from the add-on control 
device to the atmosphere.
    (ii) Car-seal or lock-and-key valve closures. Secure any bypass line 
valve in the closed position with a car-seal or a lock-and-key type 
configuration. You must visually inspect the seal or closure mechanism 
at least once every month to ensure that the valve is maintained in the 
closed position, and the emissions are not diverted away from the add-on 
control device to the atmosphere.
    (iii) Valve closure monitoring. Ensure that any bypass line valve is 
in the closed (nondiverting) position through monitoring of valve 
position at least once every 15 minutes. You must inspect the monitoring 
system at least once every month to verify that the monitor will 
indicate valve position.
    (iv) Automatic shutdown system. Use an automatic shutdown system in 
which the coating operation is stopped when flow is diverted by the 
bypass line away from the add-on control device to the atmosphere when 
the coating operation is running. You must inspect the automatic 
shutdown system at least once every month to verify

[[Page 452]]

that it will detect diversions of flow and shut down the coating 
operation.
    (2) If any bypass line is opened, you must include a description of 
why the bypass line was opened and the length of time it remained open 
in the semiannual compliance reports required in Sec. 63.3120.
    (c) Thermal oxidizers and catalytic oxidizers. If you are using a 
thermal oxidizer or catalytic oxidizer as an add-on control device 
(including those used to treat desorbed concentrate streams from 
concentrators or carbon adsorbers), you must comply with the 
requirements in paragraphs (c)(1) through (3) of this section:
    (1) For a thermal oxidizer, install a gas temperature monitor in the 
firebox of the thermal oxidizer or in the duct immediately downstream of 
the firebox before any substantial heat exchange occurs.
    (2) For a catalytic oxidizer, install a gas temperature monitor 
upstream of the catalyst bed. If you establish the operating parameters 
for a catalytic oxidizer under Sec. 63.3167(b)(1) through (3), you must 
also install a gas temperature monitor downstream of the catalyst bed. 
The temperature monitors must be in the gas stream immediately before 
and after the catalyst bed to measure the temperature difference across 
the bed. If you establish the operating parameters for a catalytic 
oxidizer under Sec. 63.3167(b)(4) through (6), you need not install a 
gas temperature monitor downstream of the catalyst bed.
    (3) For all thermal oxidizers and catalytic oxidizers, you must meet 
the requirements in paragraphs (a)(1) through (6) and (c)(3)(i) through 
(vii) of this section for each gas temperature monitoring device.
    (i) Locate the temperature sensor in a position that provides a 
representative temperature.
    (ii) Use a temperature sensor with a measurement sensitivity of 4 
degrees Fahrenheit or 0.75 percent of the temperature value, whichever 
is larger.
    (iii) Shield the temperature sensor system from electromagnetic 
interference and chemical contaminants.
    (iv) If a gas temperature chart recorder is used, it must have a 
measurement sensitivity in the minor division of at least 20 degrees 
Fahrenheit.
    (v) Perform an electronic calibration at least semiannually 
according to the procedures in the manufacturer's owners manual. 
Following the electronic calibration, you must conduct a temperature 
sensor validation check in which a second or redundant temperature 
sensor placed nearby the process temperature sensor must yield a reading 
within 30 degrees Fahrenheit of the process temperature sensor reading.
    (vi) Conduct calibration and validation checks any time the sensor 
exceeds the manufacturer's specified maximum operating temperature range 
or install a new temperature sensor.
    (vii) At least monthly, inspect components for integrity and 
electrical connections for continuity, oxidation, and galvanic 
corrosion.
    (d) Regenerative carbon adsorbers. If you are using a regenerative 
carbon adsorber as an add-on control device, you must monitor the total 
regeneration desorbing gas (e.g., steam or nitrogen) mass flow for each 
regeneration cycle, the carbon bed temperature after each regeneration 
and cooling cycle, and comply with paragraphs (a)(3) through (5) and 
(d)(1) and (2) of this section.
    (1) The regeneration desorbing gas mass flow monitor must be an 
integrating device having a measurement sensitivity of plus or minus 10 
percent, capable of recording the total regeneration desorbing gas mass 
flow for each regeneration cycle.
    (2) The carbon bed temperature monitor must have a measurement 
sensitivity of 1 percent of the temperature (as expressed in degrees 
Fahrenheit) recorded or 1 degree Fahrenheit, whichever is greater, and 
must be capable of recording the temperature within 15 minutes of 
completing any carbon bed cooling cycle.
    (e) Condensers. If you are using a condenser, you must monitor the 
condenser outlet (product side) gas temperature and comply with 
paragraphs (a)(1) through (6) and (e)(1) and (2) of this section.
    (1) The gas temperature monitor must have a measurement sensitivity

[[Page 453]]

of 1 percent of the temperature (expressed in degrees Fahrenheit) 
recorded or 1 degree Fahrenheit, whichever is greater.
    (2) The temperature monitor must provide a gas temperature record at 
least once every 15 minutes.
    (f) Concentrators. If you are using a concentrator, such as a 
zeolite wheel or rotary carbon bed concentrator, you must install a 
temperature monitor in the desorption gas stream. The temperature 
monitor must meet the requirements in paragraphs (a)(1) through (6) and 
(c)(3) of this section.
    (g) Emission capture systems. The capture system monitoring system 
must comply with the applicable requirements in paragraphs (g)(1) and 
(2) of this section.
    (1) For each flow measurement device, you must meet the requirements 
in paragraphs (a)(1) through (6) and (g)(1)(i) through (iv) of this 
section.
    (i) Locate a flow sensor in a position that provides a 
representative flow measurement in the duct from each capture device in 
the emission capture system to the add-on control device.
    (ii) Reduce swirling flow or abnormal velocity distributions due to 
upstream and downstream disturbances.
    (iii) Conduct a flow sensor calibration check at least semiannually.
    (iv) At least monthly, inspect components for integrity, electrical 
connections for continuity, and mechanical connections for leakage.
    (2) For each pressure drop measurement device, you must comply with 
the requirements in paragraphs (a)(1) through (6) and (g)(2)(i) through 
(vi) of this section.
    (i) Locate the pressure tap(s) in a position that provides a 
representative measurement of the pressure drop across each opening you 
are monitoring.
    (ii) Minimize or eliminate pulsating pressure, vibration, and 
internal and external corrosion.
    (iii) Check pressure tap pluggage daily.
    (iv) Using an inclined manometer with a measurement sensitivity of 
0.0002 inch water, check gauge calibration quarterly and transducer 
calibration monthly.
    (v) Conduct calibration checks any time the sensor exceeds the 
manufacturer's specified maximum operating pressure range or install a 
new pressure sensor.
    (vi) At least monthly, inspect components for integrity, electrical 
connections for continuity, and mechanical connections for leakage.



Sec. 63.3169  What are the requirements for a capture system or add-on
control device which is not taken into account when demonstrating
compliance with the applicable emission limitations?

    You may have capture systems or add-on control devices which you 
choose not to take into account when demonstrating compliance with the 
applicable emission limitations. For any such capture system or add-on 
control device, you are not required to comply with the requirements of 
Sec. Sec. 63.3093, 63.3100, 63.3110, 63.3120, 63.3130, 63.3131, and 
63.3160 through 63.3168 with regard to notification, reporting, 
recordkeeping, performance tests, monitoring, operating parameters, 
capture efficiency, add-on control device efficiency, destruction 
efficiency, or removal efficiency. If, at a later date, you decide to 
take any such capture system or add-on control device into account when 
demonstrating compliance with the emission limitations, then at that 
time you must comply with the requirements of Sec. Sec. 63.3093, 
63.3100, 63.3110, 63.3120, 63.3130, 63.3131, and 63.3160 through 63.3168 
with regard to notification, recordkeeping, performance tests, 
monitoring, operating parameters, capture efficiency, add-on control 
device efficiency, destruction efficiency, and removal efficiency, as 
applicable, for that capture system or add-on control device.

   Repair, Glass Bonding Primer, and Glass Bonding Adhesive Emission 
     Limitations and the Separate Electrodeposition Primer Emission 
                               Limitations



Sec. 63.3170  By what date must I conduct performance tests and
other initial compliance demonstrations?

    (a) New and reconstructed affected sources. For a new or 
reconstructed affected source, you must meet the requirements of 
paragraphs (a)(1) through (4) of Sec. 63.3160.
    (b) Existing affected sources. For an existing affected source, you 
must meet the requirements of paragraphs (b)(1) through (3) of Sec. 
63.3160.



Sec. 63.3171  How do I demonstrate initial compliance?

    (a) You must meet all of the requirements of this section to 
demonstrate initial compliance. To demonstrate initial compliance, the 
organic HAP emissions from the combined primer-surfacer, topcoat, final 
repair, glass bonding primer, and glass bonding adhesive operations plus 
all coatings and thinners, except for deadener materials and for 
adhesive and sealer materials that are not components of glass bonding 
systems, used in coating operations added to the affected source 
pursuant to Sec. 63.3082(c) must meet the applicable emission 
limitation in Sec. 63.3090(b) or Sec. 63.3091(b); and the organic HAP 
emissions from the electrodeposition primer operation must meet the 
applicable emissions limitations in Sec. 63.3092(a) or (b).
    (b) Compliance with operating limits. Except as provided in Sec. 
63.3160(a)(4), you must establish and demonstrate continuous compliance 
during the initial compliance period with the operating limits required 
by Sec. 63.3093, using the procedures specified in Sec. Sec. 63.3167 
and 63.3168.
    (c) Compliance with work practice requirements. You must develop, 
implement, and document your implementation of the work practice plans 
required by Sec. 63.3094(b) and (c) during the initial compliance 
period, as specified in Sec. 63.3130.
    (d) Compliance with emission limits. You must follow the procedures 
in Sec. 63.3161(e) through (n), excluding materials used in 
electrodeposition primer operations, to demonstrate compliance with the 
applicable emission limit in Sec. 63.3090(b) or Sec. 63.3091(b). You 
must follow the procedures in paragraph (e) of this section to 
demonstrate compliance with the emission limit in Sec. 63.3092(a), or 
paragraphs (f) through (g) of this section to demonstrate compliance 
with the emission limitations in Sec. 63.3092(b).
    (e) Determine the mass fraction of each organic HAP in each material 
used in the electrodeposition primer operation. You must determine the 
mass fraction of each organic HAP for each material used in the 
electrodeposition primer operation during the compliance period by using 
one of the options in paragraphs (e)(1) through (3) of this section.
    (1) Method 311 (appendix A to 40 CFR part 63). You may use Method 
311 for determining the mass fraction of each organic HAP.
    (2) Alternative method. You may use an alternative test method for 
determining the mass fraction of organic HAP once the Administrator has 
approved it. You must follow the procedure in Sec. 63.7(f) to submit an 
alternative test method for approval.
    (3) Information from the supplier or manufacturer of the material. 
You may rely on information other than that generated by the test 
methods specified in paragraphs (e)(1) and (2) of this section, such as 
manufacturer's formulation data, if it represents each organic HAP that 
is present at 0.1 percent by mass or more for OSHA-defined carcinogens, 
as specified in 29 CFR 1910.1200(d)(4), and at 1.0 percent by mass or 
more for other compounds. If there is a disagreement between such 
information and results of a test conducted according to paragraph 
(e)(1) or (2) of this section, then the test method results will take 
precedence unless after consultation, the facility demonstrates to the 
satisfaction of the enforcement authority that the facility's data are 
correct.
    (f) Capture of electrodeposition bake oven emissions. You must show 
that the electrodeposition bake oven meets the criteria in sections 5.3 
through 5.5 of

[[Page 455]]

Method 204 of appendix M to 40 CFR part 51 and directs all of the 
exhaust gases from the bake oven to an add-on control device. For 
purposes of this showing, an electrodeposition bake oven air seal is not 
considered a natural draft opening provided you demonstrate that the 
direction of air movement across the interface between the bake oven air 
seal and the bake oven is into the bake oven. You may use lightweight 
strips of fabric or paper, or smoke tubes to make such demonstrations. 
You cannot count air flowing from an electrodeposition bake oven air 
seal into an electrodeposition bake oven as air flowing through a 
natural draft opening unless you elect to treat that electrodeposition 
bake oven air seal as a natural draft opening.
    (g) Control of electrodeposition bake oven emissions. Determine the 
efficiency of each control device on each electrodeposition bake oven 
using the procedures in Sec. Sec. 63.3164 and 63.3166.
    (h) Compliance demonstration. To demonstrate initial compliance, the 
organic HAP emissions from the combined primer-surfacer, topcoat, final 
repair, glass bonding primer, and glass bonding adhesive operations plus 
all coatings and thinners, except for deadener materials and for 
adhesive and sealer materials that are not components of glass bonding 
systems, used in coating operations added to the affected source 
pursuant to Sec. 63.3082(c) must meet the applicable emission 
limitation in Sec. 63.3090(b) or Sec. 63.3091(b); the organic HAP 
emissions from the electrodeposition primer operation must meet the 
applicable emissions limitations in Sec. 63.3092(a) or (b). You must 
keep all records as required by Sec. Sec. 63.3130 and 63.3131. As part 
of the Notification of Compliance Status required by Sec. 63.3110, you 
must submit a statement that the coating operation(s) was (were) in 
compliance with the emission limitations during the initial compliance 
period because the organic HAP emission rate from the combined primer-
surfacer, topcoat, final repair, glass bonding primer, and glass bonding 
adhesive operations plus all coatings and thinners, except for deadener 
materials and for adhesive and sealer materials that are not components 
of glass bonding systems, used in coating operations added to the 
affected source pursuant to Sec. 63.3082(c) was less than or equal to 
the applicable emission limit in Sec. 63.3090(b) or Sec. 63.3091(b), 
and the organic HAP emissions from the electrodeposition primer 
operation met the applicable emissions limitations in Sec. 63.3092(a) 
or (b), and you achieved the operating limits required by Sec. 63.3093 
and the work practice standards required by Sec. 63.3094.

Sec. 63.3172  [Reserved]



Sec. 63.3173  How do I demonstrate continuous compliance with the
emission limitations?

    (a) To demonstrate continuous compliance with the applicable 
emission limit in Sec. 63.3090(b) or Sec. 63.3091(b), the organic HAP 
emission rate for each compliance period determined according to the 
procedures in Sec. 63.3171 must be equal to or less than the applicable 
emission limit in Sec. 63.3090(b) or Sec. 63.3091(b). A compliance 
period consists of 1 month. Each month after the end of the initial 
compliance period described in Sec. 63.3170 is a compliance period 
consisting of that month. You must perform the calculations in Sec. 
63.3171 on a monthly basis.
    (b) If the organic HAP emission rate for any 1 month compliance 
period exceeded the applicable emission limit in Sec. 63.3090(b) or 
Sec. 63.3091(b), this is a deviation from the emission limitation for 
that compliance period and must be reported as specified in Sec. Sec. 
63.3110(c)(6) and 63.3120(a)(6).
    (c) You must meet the requirements of Sec. 63.3163(c) through (j).



Sec. 63.3174  What are the requirements for a capture system or 
add-on control device which is not taken into account when 
demonstrating compliance with the applicable emission limitations?

    You may have capture systems or add-on control devices which you 
choose not to take into account when demonstrating compliance with the 
applicable emission limitations. For any such capture system or add-on 
control device, you are not required to comply with the requirements of 
Sec. Sec. 63.3093, 63.3100, 63.3110, 63.3120, 63.3130, 63.3131,

[[Page 456]]

and 63.3160 through 63.3168 with regard to notification, reporting, 
recordkeeping, performance tests, monitoring, operating parameters, 
capture efficiency, add-on control device efficiency, destruction 
efficiency, or removal efficiency. If, at a later date, you decide to 
take any such capture system or add-on control device into account when 
demonstrating compliance with the emission limitations, then at that 
time you must comply with the requirements of Sec. Sec. 63.3093, 
63.3100, 63.3110, 63.3120, 63.3130, 63.3131, and 63.3160 through 63.3168 
with regard to notification, reporting, recordkeeping, performance 
tests, monitoring, operating parameters, capture efficiency, add-on 
control device efficiency, destruction efficiency, and removal 
efficiency, as applicable, for that capture system or add-on control 
device.

Sec. 63.3175  Who implements and enforces this subpart?

    (a) This subpart can be implemented and enforced by us, EPA, or a 
delegated authority such as your State, local, or tribal agency. If the 
Administrator has delegated authority to your State, local, or tribal 
agency, then that agency (as well as EPA) has the authority to implement 
and enforce this subpart. You should contact your EPA Regional Office to 
find out if implementation and enforcement of this subpart is delegated 
to your State, local, or tribal agency.
    (b) In delegating implementation and enforcement authority of this 
subpart to a State, local, or tribal agency under subpart E of this 
part, the authorities contained in paragraph (c) of this section are 
retained by the EPA Administrator and are not transferred to the State, 
local, or tribal agency.
    (c) The authorities that will not be delegated to State, local, or 
tribal agencies are listed in paragraphs (c)(1) through (4) of this 
section:
    (1) Approval of alternatives to the work practice standards in Sec. 
63.3094 under Sec. 63.6(g).

vestibule from a bake oven which isolates the bake oven from the area 
immediately preceding (for an entry or entry vestibule) or immediately 
following (for an exit or exit vestibule) the bake oven. No significant 
VOC generating activity takes place in a bake oven air seal. Fresh air 
is supplied into a bake oven air seal and is then directed in part into 
the bake oven and in part into the area immediately preceding or 
immediately following the bake oven. All types of bake ovens, including 
ovens associated with spray booths and electrodeposition primer bake 
ovens, may have bake oven air seals.

booths, spray guns, tanks, and hangers. Thus, it includes any cleaning 
material used on substrates or equipment or both.
    Coating means a material applied to a substrate for decorative, 
protective, or functional purposes. Such materials include, but are not 
limited to, paints, sealants, caulks, inks, adhesives, primers,

that consist only of protective oils for metal, acids, bases, or any 
combination of these substances are not considered coatings for the 
purposes of this subpart.
    Coating operation means equipment used to apply coating to a 
substrate (coating application) and to dry or cure the coating after 
application. A single coating operation always includes at least the 
point at which a coating is applied and all subsequent points in the 
affected source where organic HAP emissions from that coating occur. 
There may be multiple coating operations in an affected source. Coating 
application with hand-held nonrefillable aerosol containers, touchup 
bottles, touchup markers, marking pens, or pinstriping equipment is not 
a coating operation for the purposes of this subpart. The application of

requirement or obligation established by this subpart including, but not 
limited to, any emission limit, operating limit, or work practice 
standard; fails to meet any term or condition that is adopted to 
implement an applicable requirement in this subpart and that is included 
in the operating permit for any affected source required to obtain such 
a permit; or fails to meet any emission limit or operating limit or work 
practice standard in this subpart during startup, shutdown, or 
malfunction, regardless of whether or not such failure is permitted by 
this subpart. A deviation is not always a violation.

completely assembled motor vehicle to correct damage or imperfections in 
the coating. The curing of the coatings applied in these operations is 
accomplished at a lower temperature than that used for curing primer-
surfacer and topcoat. This lower temperature cure avoids the need to 
send parts that are not yet on a completely assembled vehicle through 
the same type of curing process used for primer-surfacer and topcoat and 
is necessary to protect heat sensitive components on completely 
assembled motor vehicles.
    Flash-off area means the portion of a coating process between the

  Sec. Appendix A to Subpart IIII of Part 63--Determination of Capture 
Efficiency of Automobile and Light-Duty Truck Spray Booth Emissions From 
               Solvent-borne Coatings Using Panel Testing

    1.0 Applicability, Principle, and Summary of Procedure.
    1.1 Applicability.
    This procedure applies to the determination of capture efficiency of 
automobile and light-duty truck spray booth emissions from solvent-borne 
coatings using panel testing. This procedure can be used to determine 
capture efficiency for partially controlled spray booths (e.g., 
automated spray zones controlled and manual spray zones not controlled) 
and for fully controlled spray booths.
    1.2 Principle.

[[Page 467]]

    1.2.1 The volatile organic compounds (VOC) associated with the 
coating solids deposited on a part (or panel) in a controlled spray 
booth zone (or group of contiguous controlled spray booth zones) 
partition themselves between the VOC that volatilize in the controlled 
spray booth zone (principally between the spray gun and the part) and 
the VOC that remain on the part (or panel) when the part (or panel) 
leaves the controlled spray booth zone. For solvent-borne coatings 
essentially all of the VOC associated with the coating solids deposited 
on a part (or panel) in a controlled spray booth zone that volatilize in 
the controlled spray booth zone pass through the waterwash and are 
exhausted from the controlled spray booth zone to the control device.
    1.2.2 The VOC associated with the overspray coating solids in a 
controlled spray booth zone partition themselves between the VOC that 
volatilize in the controlled spray booth zone and the VOC that are still 
tied to the overspray coating solids when the overspray coating solids 
hit the waterwash. For solvent-borne coatings almost all of the VOC 
associated with the overspray coating solids that volatilize in the 
controlled spray booth zone pass through the waterwash and are exhausted 
from the controlled spray booth zone to the control device. The exact 
fate of the VOC still tied to the overspray coating solids when the 
overspray coating solids hit the waterwash is unknown. This procedure 
assumes that none of the VOC still tied to the overspray coating solids 
when the overspray coating solids hit the waterwash are captured and 
delivered to the control device. Much of this VOC may become entrained 
in the water along with the overspray coating solids. Most of the VOC 
that become entrained in the water along with the overspray coating 
solids leave the water, but the point at which this VOC leave the water 
is unknown. Some of the VOC still tied to the overspray coating solids 
when the overspray coating solids hit the waterwash may pass through the 
waterwash and be exhausted from the controlled spray booth zone to the 
control device.
    1.2.3 This procedure assumes that the portion of the VOC associated 
with the overspray coating solids in a controlled spray booth zone that 
volatilizes in the controlled spray booth zone, passes through the 
waterwash and is exhausted from the controlled spray booth zone to the 
control device is equal to the portion of the VOC associated with the 
coating solids deposited on a part (or panel) in that controlled spray 
booth zone that volatilizes in the controlled spray booth zone, passes 
through the waterwash, and is exhausted from the controlled spray booth 
zone to the control device. This assumption is equivalent to treating 
all of the coating solids sprayed in the controlled spray booth zone as 
if they are deposited coating solids (i.e., assuming 100 percent 
transfer efficiency) for purposes of using a panel test to determine 
spray booth capture efficiency.
    1.2.4 This is a conservative (low) assumption for the portion of the 
VOC associated with the overspray coating solids in a controlled spray 
booth zone that volatilizes in the controlled spray booth zone. Thus, 
this assumption results in an underestimate of conservative capture 
efficiency. The overspray coating solids have more travel time and 
distance from the spray gun to the waterwash than the deposited coating 
solids have between the spray gun and the part (or panel). Therefore, 
the portion of the VOC associated with the overspray coating solids in a 
controlled spray booth zone that volatilizes in the controlled spray 
booth zone should be greater than the portion of the VOC associated with 
the coating solids deposited on a part (or panel) in that controlled 
spray booth zone that volatilizes in that controlled spray booth zone.
    1.3 Summary of Procedure.
    1.3.1 A panel test is performed to determine the mass of VOC that 
remains on the panel when the panel leaves a controlled spray booth 
zone. The total mass of VOC associated with the coating solids deposited 
on the panel is calculated.
    1.3.2 The percent of the total VOC associated with the coating 
solids deposited on the panel in the controlled spray booth zone that 
remains on the panel when the panel leaves the controlled section of the 
spray booth is then calculated from the ratio of the two previously 
determined masses. The percent of the total VOC associated with the 
coating solids deposited on the panel in the controlled spray booth zone 
that is captured and delivered to the control device equals 100 minus 
this percentage. (The mass of VOC associated with the coating solids 
deposited on the panel which is volatilized and captured in the 
controlled spray booth zone equals the difference between the total mass 
of VOC associated with the coating solids deposited on the panel and the 
mass of VOC remaining with the coating solids deposited on the panel 
when the panel leaves the controlled spray booth zone.)
    1.3.3 The percent of the total VOC associated with the coating 
sprayed in the controlled spray booth zone that is captured and 
delivered to the control device is assumed to be equal to the percent of 
the total VOC associated with the coating solids deposited on the panel 
in the controlled spray booth zone that is captured and delivered to the 
control device. The percent of the total VOC associated with the coating 
sprayed in the entire spray booth that is captured and delivered to the 
control device can be calculated by multiplying the percent of the total 
VOC associated with the coating sprayed in the controlled spray booth 
zone that is captured and

[[Page 468]]

delivered to the control device by the fraction of coating sprayed in 
the spray booth that is sprayed in the controlled spray booth zone.
    2.0 Procedure.
    2.1 You may conduct panel testing to determine the capture 
efficiency of spray booth emissions. You must follow the instructions 
and calculations in this appendix A, and use the panel testing 
procedures in ASTM Method D5087-02, ``Standard Test Method for 
Determining Amount of Volatile Organic Compound (VOC) Released from 
Solventborne Automotive Coatings and Available for Removal in a VOC 
Control Device (Abatement)'' (incorporated by reference, see Sec. 
63.14), or the guidelines presented in ``Protocol for Determining Daily 
Volatile Organic Compound Emission Rate of Automobile and Light-Duty 
Truck Topcoat Operations,'' EPA-450/3-88-018 (Docket ID No. OAR-2002-
0093 and Docket ID No. A-2001-22). You must weigh panels at the points 
described in section 2.5 of this appendix A and perform calculations as 
described in sections 3 and 4 of this appendix A. You may conduct panel 
tests on the production paint line in your facility or in a laboratory 
simulation of the production paint line in your facility.
    2.2 You may conduct panel testing on representative coatings as 
described in ``Protocol for Determining Daily Volatile Organic Compound 
Emission Rate of Automobile and Light-Duty Truck Topcoat Operations,'' 
EPA-450/3-88-018 (Docket ID No. OAR-2002-0093 and Docket ID No. A-2001-
22). If you panel test representative coatings, then you may calculate 
either a unique percent capture efficiency value for each coating 
grouped with that representative coating, or a composite percent capture 
efficiency value for the group of coatings. If you panel test each 
coating, then you must convert the panel test result for each coating to 
a unique percent capture efficiency value for that coating.
    2.3 Identification of Controlled Spray Booth Zones.
    You must identify each controlled spray booth zone or each group of 
contiguous controlled spray booth zones to be tested. (For example, a 
controlled bell zone immediately followed by a controlled robotic zone.) 
Separate panel tests are required for non-contiguous controlled spray 
booth zones. The flash zone between the last basecoat zone and the first 
clearcoat zone makes these zones non-contiguous.
    2.4 Where to Apply Coating to the Panel.
    If you are conducting a panel test for a single controlled spray 
booth zone, then you must apply coating to the panel only in that 
controlled spray booth zone. If you are conducting a panel test for a 
group of contiguous controlled spray booth zones, then you must apply 
coating to the panel only in that group of contiguous controlled spray 
booth zones.
    2.5 How to Process and When to Weigh the Panel.
    The instructions in this section pertain to panel testing of 
coating, i, or of the coating representing the group of coatings that 
includes coating, i.
    2.5.1 You must weigh the blank panel. (Same as in bake oven panel 
test.) The mass of the blank panel is represented by Wblank,i 
(grams).
    2.5.2 Apply coating, i, or the coating representing coating, i, to 
the panel in the controlled spray booth zone or group of contiguous 
controlled spray booth zones being tested (in plant test), or in a 
simulation of the controlled spray booth zone or group of contiguous 
controlled spray booth zones being tested (laboratory test).
    2.5.3 Remove and weigh the wet panel as soon as the wet panel leaves 
the controlled spray booth zone or group of contiguous controlled spray 
booth zones being tested. (Different than bake oven panel test.) This 
weighing must be conducted quickly to avoid further evaporation of VOC. 
The mass of the wet panel is represented by Wwet,i (grams).
    2.5.4 Return the wet panel to the point in the coating process or 
simulation of the coating process where it was removed for weighing.
    2.5.5 Allow the panel to travel through the rest of the coating 
process in the plant or laboratory simulation of the coating process. 
You must not apply any more coating to the panel after it leaves the 
controlled spray booth zone (or group of contiguous controlled spray 
booth zones) being tested. The rest of the coating process or simulation 
of the coating process consists of:
    2.5.5.1 All of the spray booth zone(s) or simulation of all of the 
spray booth zone(s) located after the controlled spray booth zone or 
group of contiguous controlled spray booth zones being tested and before 
the bake oven where the coating applied to the panel is cured,
    2.5.5.2 All of the flash-off area(s) or simulation of all of the 
flash-off area(s) located after the controlled spray booth zone or group 
of contiguous controlled spray booth zones being tested and before the 
bake oven where the coating applied to the panel is cured, and
    2.5.5.3 The bake oven or simulation of the bake oven where the 
coating applied to the panel is cured.
    2.5.6 After the panel exits the bake oven, you must cool and weigh 
the baked panel. (Same as in bake oven panel test.) The mass of the 
baked panel is represented by Wbaked,i (grams).
    3.0 Panel Calculations.
    The instructions in this section pertain to panel testing of 
coating, i, or of the coating

[[Page 469]]

representing the group of coatings that includes coating, i.
    3.1 The mass of coating solids (from coating, i, or from the coating 
representing coating, i, in the panel test) deposited on the panel 
equals the mass of the baked panel minus the mass of the blank panel as 
shown in Equation A-1.
[GRAPHIC] [TIFF OMITTED] TR26AP04.028

Where:

Wsdep, i = Mass of coating solids (from coating, i, or from 
          the coating representing coating, i, in the panel test) 
          deposited on the panel, grams.

    3.2 The mass of VOC (from coating, i, or from the coating 
representing coating, i, in the panel test) remaining on the wet panel 
when the wet panel leaves the controlled spray booth zone or group of 
contiguous controlled spray booth zones being tested equals the mass of

    4.0 Converting Panel Result to Percent Capture.
    The instructions in this section pertain to panel testing of for 
coating, i, or of the coating representing the group of coatings that 
includes coating, i.
    4.1 If you panel test representative coatings, then you may convert 
the panel test result for each representative coating from section 3.3 
of this appendix A either to a unique percent capture efficiency value 
for each coating grouped with that representative coating by using 
coating specific values for the mass fraction coating solids and mass 
fraction VOC in section 4.2 of this appendix A, or to a composite 
percent capture efficiency value for the group of coatings by using the 
average values for the group of coatings for mass fraction coating 
solids and mass fraction VOC in section 4.2 of this appendix A. If you 
panel test each coating, then you must convert the panel test result for 
each coating to a unique percent capture efficiency value by using 
coating specific values for the mass fraction coating solids and mass 
fraction VOC in section 4.2 of this appendix A. The mass fraction of VOC 
in the coating and the mass fraction of solids in the coating must be 
determined by Method 24 (appendix A to 40 CFR part 60) or by following 
the guidelines for combining analytical VOC content and formulation 
solvent content presented in ``Protocol for Determining Daily Volatile 
Organic Compound Emission Rate of Automobile and Light-Duty Truck 
Topcoat Operations,'' EPA-450/3-88-018 (Docket ID No. OAR-2002-0093 and

for the group of coatings including coating, i, associated with the 
coating solids deposited on the panel that remains on the wet panel when 
the wet panel leaves the controlled spray booth zone or group of 
contiguous controlled spray booth zones being tested is calculated using

sprayed in the entire spray booth may be determined from gun on times 
and fluid flow rates or from direct measurements of coating usage.

    4.5 If you conduct multiple panel tests for the same coating or same 
group of coatings in the same spray booth (either because the coating or 
group of coatings is controlled in non-contiguous zones of the spray 
booth, or because you choose to conduct separate panel tests for 
contiguous controlled spray booth zones), then you may add the result 
from section 4.4 for each such panel test to get the total capture 
efficiency for the coating or group of coatings over all of the 
controlled zones in the spray booth for the coating or group of 
coatings.

this part that apply if you are subject to this subpart, such as 
startup, shutdown, and malfunction plans (SSMP) in Sec. 63.6(e)(3) for 
affected sources using a control device to comply with the emission 
standards.



Sec. 63.3350  If I use a control device to comply with the emission
standards, what monitoring must I do?

    (a) A summary of monitoring you must do follows:

[[Page 475]]



------------------------------------------------------------------------
 If you operate a web coating
line, and have the following:                Then you must:
------------------------------------------------------------------------
(1) Intermittently-controlled  Record parameters related to possible
 work stations.                 exhaust flow bypass of control device
                                and to coating use (Sec. 63.3350(c)).
(2) Solvent recovery unit....  Operate continuous emission monitoring
                                system and perform quarterly audits or
                                determine volatile matter recovered and
                                conduct a liquid-liquid material balance
                                (Sec. 63.3350(d)).
(3) Control Device...........  Operate continuous parameter monitoring
                                system (Sec. 63.3350(e)).
(4) Capture system...........  Monitor capture system operating
                                parameter (Sec. 63.3350(f)).
------------------------------------------------------------------------

    (b) Following the date on which the initial performance test of a 
control device is completed to demonstrate continuing compliance with 
the standards, you must monitor and inspect each capture system and each 
control device used to comply with Sec. 63.3320. You must install and 
operate the monitoring equipment as specified in paragraphs (c) and (f) 
of this section.
    (c) Bypass and coating use monitoring. If you own or operate web 
coating lines with intermittently-controlled work stations, you must 
monitor bypasses of the control device and the mass of each coating 
material applied at the work station during any such bypass. If using a 
control device for complying with the requirements of this subpart, you 
must demonstrate that any coating material applied on a never-controlled 
work station or an intermittently-controlled work station operated in 
bypass mode is allowed in your compliance demonstration according to 
Sec. 63.3370(n) and (o). The bypass monitoring must be conducted using 
at least one of the procedures in paragraphs (c)(1) through (4) of this 
section for each work station and associated dryer.
    (1) Flow control position indicator. Install, calibrate, maintain, 
and operate according to the manufacturer's specifications a flow 
control position indicator that provides a record indicating whether the 
exhaust stream from the dryer was directed to the control device or was 
diverted from the control device. The time and flow control position 
must be recorded at least once per hour as well as every time the flow 
direction is changed. A flow control position indicator must be 
installed at the entrance to any bypass line that could divert the 
exhaust stream away from the control device to the atmosphere.
    (2) Car-seal or lock-and-key valve closures. Secure any bypass line 
valve in the closed position with a car-seal or a lock-and-key type 
configuration. A visual inspection of the seal or closure mechanism must 
be performed at least once every month to ensure that the valve or 
damper is maintained in the closed position, and the exhaust stream is 
not diverted through the bypass line.
    (3) Valve closure continuous monitoring. Ensure that any bypass line 
valve or damper is in the closed position through continuous monitoring 
of valve position when the emission source is in operation and is using 
a control device for compliance with the requirements of this subpart. 
The monitoring system must be inspected at least once every month to 
verify that the monitor will indicate valve position.
    (4) Automatic shutdown system. Use an automatic shutdown system in 
which the web coating line is stopped when flow is diverted away from 
the control device to any bypass line when the control device is in 
operation. The automatic system must be inspected at least once every 
month to verify that it will detect diversions of flow and would shut 
down operations in the event of such a diversion.
    (d) Solvent recovery unit. If you own or operate a solvent recovery 
unit to comply with Sec. 63.3320, you must meet the requirements in 
either paragraph (d)(1) or (2) of this section depending on how control 
efficiency is determined.
    (1) Continuous emission monitoring system (CEMS). If you are 
demonstrating compliance with the emission standards in Sec. 63.3320 
through continuous emission monitoring of a control device, you must 
install, calibrate, operate, and maintain the CEMS according to 
paragraphs (d)(1)(i) through (iii) of this section.
    (i) Measure the total organic volatile matter mass flow rate at both 
the control device inlet and the outlet such

[[Page 476]]

that the reduction efficiency can be determined. Each continuous 
emission monitor must comply with performance specification 6, 8, or 9 
of 40 CFR part 60, appendix B, as appropriate.
    (ii) You must follow the quality assurance procedures in procedure 
1, appendix F of 40 CFR part 60. In conducting the quarterly audits of 
the monitors as required by procedure 1, appendix F, you must use 
compounds representative of the gaseous emission stream being 
controlled.
    (iii) You must have valid data from at least 90 percent of the hours 
during which the process is operated.
    (2) Liquid-liquid material balance. If you are demonstrating 
compliance with the emission standards in Sec. 63.3320 through liquid-
liquid material balance, you must install, calibrate, maintain, and 
operate according to the manufacturer's specifications a device that 
indicates the cumulative amount of volatile matter recovered by the 
solvent recovery device on a monthly basis. The device must be certified 
by the manufacturer to be accurate to within 2.0 
percent by mass.
    (e) Continuous parameter monitoring system (CPMS). If you are using 
a control device to comply with the emission standards in Sec. 63.3320, 
you must install, operate, and maintain each CPMS specified in 
paragraphs (e)(9) and (10) and (f) of this section according to the 
requirements in paragraphs (e)(1) through (8) of this section. You must 
install, operate, and maintain each CPMS specified in paragraph (c) of 
this section according to paragraphs (e)(5) through (7) of this section.
    (1) Each CPMS must complete a minimum of one cycle of operation for 
each successive 15-minute period. You must have a minimum of four 
equally spaced successive cycles of CPMS operation to have a valid hour 
of data.
    (2) You must have valid data from at least 90 percent of the hours 
during which the process operated.
    (3) You must determine the hourly average of all recorded readings 
according to paragraphs (e)(3)(i) and (ii) of this section.
    (i) To calculate a valid hourly value, you must have at least three 
of four equally spaced data values from that hour from a continuous 
monitoring system (CMS) that is not out-of-control.
    (ii) Provided all of the readings recorded in accordance with 
paragraph (e)(3) of this section clearly demonstrate continuous 
compliance with the standard that applies to you, then you are not 
required to determine the hourly average of all recorded readings.
    (4) You must determine the rolling 3-hour average of all recorded 
readings for each operating period. To calculate the average for each 3-
hour averaging period, you must have at least two of three of the hourly 
averages for that period using only average values that are based on 
valid data (i.e., not from out-of-control periods).
    (5) You must record the results of each inspection, calibration, and 
validation check of the CPMS.
    (6) At all times, you must maintain the monitoring system in proper 
working order including, but not limited to, maintaining necessary parts 
for routine repairs of the monitoring equipment.
    (7) Except for monitoring malfunctions, associated repairs, or 
required quality assurance or control activities (including calibration 
checks or required zero and span adjustments), you must conduct all 
monitoring at all times that the unit is operating. Data recorded during 
monitoring malfunctions, associated repairs, out-of-control periods, or 
required quality assurance or control activities shall not be used for 
purposes of calculating the emissions concentrations and percent 
reductions specified in Sec. 63.3370. You must use all the valid data 
collected during all other periods in assessing compliance of the 
control device and associated control system. A monitoring malfunction 
is any sudden, infrequent, not reasonably preventable failure of the 
monitoring system to provide valid data. Monitoring failures that are 
caused in part by poor maintenance or careless operation are not 
malfunctions.
    (8) Any averaging period for which you do not have valid monitoring 
data and such data are required constitutes a deviation, and you must 
notify the Administrator in accordance with Sec. 63.3400(c).

[[Page 477]]

    (9) Oxidizer. If you are using an oxidizer to comply with the 
emission standards, you must comply with paragraphs (e)(9)(i) through 
(iii) of this section.
    (i) Install, calibrate, maintain, and operate temperature monitoring 
equipment according to the manufacturer's specifications. The 
calibration of the chart recorder, data logger, or temperature indicator 
must be verified every 3 months or the chart recorder, data logger, or 
temperature indicator must be replaced. You must replace the equipment 
whether you choose not to perform the calibration or the equipment 
cannot be calibrated properly.
    (ii) For an oxidizer other than a catalytic oxidizer, install, 
calibrate, operate, and maintain a temperature monitoring device 
equipped with a continuous recorder. The device must have an accuracy of 
1 percent of the temperature being monitored in 
degrees Celsius, or 1 [deg]Celsius, whichever is 
greater. The thermocouple or temperature sensor must be installed in the 
combustion chamber at a location in the combustion zone.
    (iii) For a catalytic oxidizer, install, calibrate, operate, and 
maintain a temperature monitoring device equipped with a continuous 
recorder. The device must be capable of monitoring temperature with an 
accuracy of 1 percent of the temperature being 
monitored in degrees Celsius or 1 degree Celsius, 
whichever is greater. The thermocouple or temperature sensor must be 
installed in the vent stream at the nearest feasible point to the inlet 
and outlet of the catalyst bed. Calculate the temperature rise across 
the catalyst.
    (10) Other types of control devices. If you use a control device 
other than an oxidizer or wish to monitor an alternative parameter and 
comply with a different operating limit, you must apply to the 
Administrator for approval of an alternative monitoring method under 
Sec. 63.8(f).
    (f) Capture system monitoring. If you are complying with the 
emission standards in Sec. 63.3320 through the use of a capture system 
and control device for one or more web coating lines, you must develop a 
site-specific monitoring plan containing the information specified in 
paragraphs (f)(1) and (2) of this section for these capture systems. You 
must monitor the capture system in accordance with paragraph (f)(3) of 
this section. You must make the monitoring plan available for inspection 
by the permitting authority upon request.
    (1) The monitoring plan must:
    (i) Identify the operating parameter to be monitored to ensure that 
the capture efficiency determined during the initial compliance test is 
maintained; and
    (ii) Explain why this parameter is appropriate for demonstrating 
ongoing compliance; and
    (iii) Identify the specific monitoring procedures.
    (2) The monitoring plan must specify the operating parameter value 
or range of values that demonstrate compliance with the emission 
standards in Sec. 63.3320. The specified operating parameter value or 
range of values must represent the conditions present when the capture 
system is being properly operated and maintained.
    (3) You must conduct all capture system monitoring in accordance 
with the plan.
    (4) Any deviation from the operating parameter value or range of 
values which are monitored according to the plan will be considered a 
deviation from the operating limit.
    (5) You must review and update the capture system monitoring plan at 
least annually.



Sec. 63.3360  What performance tests must I conduct?

    (a) The performance test methods you must conduct are as follows:

[[Page 478]]

                                     63.3360(c) and (d). If applicable,
                                     determine the mass of volatile
                                     matter retained in the coated web
                                     or otherwise not emitted to the
                                     atmosphere according to Sec.
                                     63.3360(g).
(2) Using a capture and control     Conduct a performance test for each
 system.                             capture and control system to
                                     determine: the destruction or
                                     removal efficiency of each control
                                     device other than solvent recovery
                                     according to Sec. 63.3360(e), and
                                     the capture efficiency of each
                                     capture system according to Sec.
                                     63.3360(f). If applicable,
                                     determine the mass of volatile
                                     matter retained in the coated web
                                     or otherwise not emitted to the
                                     atmosphere according to Sec.
                                     63.3360(g).
------------------------------------------------------------------------

    (b) If you are using a control device to comply with the emission 
standards in Sec. 63.3320, you are not required to conduct a 
performance test to demonstrate compliance if one or more of the 
criteria in paragraphs (b)(1) through (3) of this section are met.
    (1) The control device is equipped with continuous emission monitors 
for determining inlet and outlet total organic volatile matter 
concentration and capture efficiency has been determined in accordance 
with the requirements of this subpart such that an overall organic HAP 
control efficiency can be calculated, and the continuous emission 
monitors are used to demonstrate continuous compliance in accordance 
with Sec. 63.3350; or
    (2) You have met the requirements of Sec. 63.7(h) (for waiver of 
performance testing; or
    (3) The control device is a solvent recovery system and you comply 
by means of a monthly liquid-liquid material balance.
    (c) Organic HAP content. If you determine compliance with the 
emission standards in Sec. 63.3320 by means other than determining the 
overall organic HAP control efficiency of a control device, you must 
determine the organic HAP mass fraction of each coating material ``as-
purchased'' by following one of the procedures in paragraphs (c)(1) 
through (3) of this section, and determine the organic HAP mass fraction 
of each coating material ``as-applied'' by following the procedures in 
paragraph (c)(4) of this section. If the organic HAP content values are 
not determined using the procedures in paragraphs (c)(1) through (3) of 
this section, the owner or operator must submit an alternative test 
method for determining their values for approval by the Administrator in 
accordance with Sec. 63.7(f). The recovery efficiency of the test 
method must be determined for all of the target organic HAP and a 
correction factor, if necessary, must be determined and applied.
    (1) Method 311. You may test the coating material in accordance with 
Method 311 of appendix A of this part. The Method 311 determination may 
be performed by the manufacturer of the coating material and the results 
provided to the owner or operator. The organic HAP content must be 
calculated according to the criteria and procedures in paragraphs 
(c)(1)(i) through (iii) of this section.
    (i) Include each organic HAP determined to be present at greater 
than or equal to 0.1 mass percent for Occupational Safety and Health 
Administration (OSHA)-defined carcinogens as specified in 29 CFR 
1910.1200(d)(4) and greater than or equal to 1.0 mass percent for other 
organic HAP compounds.
    (ii) Express the mass fraction of each organic HAP you include 
according to paragraph (c)(1)(i) of this section as a value truncated to 
four places after the decimal point (for example, 0.3791).
    (iii) Calculate the total mass fraction of organic HAP in the tested 
material by summing the counted individual organic HAP mass fractions 
and truncating the result to three places after the decimal point (for 
example, 0.763).
    (2) Method 24. For coatings, determine the volatile organic content 
as mass fraction of nonaqueous volatile matter and use it as a 
substitute for organic HAP using Method 24 of 40 CFR part 60, appendix 
A. The Method 24 determination may be performed by the manufacturer of 
the coating and the results provided to you.

[[Page 479]]

    (3) Formulation data. You may use formulation data to determine the 
organic HAP mass fraction of a coating material. Formulation data may be 
provided to the owner or operator by the manufacturer of the material. 
In the event of an inconsistency between Method 311 (appendix A of 40 
CFR part 63) test data and a facility's formulation data, and the Method 
311 test value is higher, the Method 311 data will govern. Formulation 
data may be used provided that the information represents all organic 
HAP present at a level equal to or greater than 0.1 percent for OSHA-
defined carcinogens as specified in 29 CFR 1910.1200(d)(4) and equal to 
or greater than 1.0 percent for other organic HAP compounds in any raw 
material used.
    (4) As-applied organic HAP mass fraction. If the as-purchased 
coating material is applied to the web without any solvent or other 
material added, then the as-applied organic HAP mass fraction is equal 
to the as-purchased organic HAP mass fraction. Otherwise, the as-applied 
organic HAP mass fraction must be calculated using Equation 1a of Sec. 
63.3370.
    (d) Volatile organic and coating solids content. If you determine 
compliance with the emission standards in Sec. 63.3320 by means other 
than determining the overall organic HAP control efficiency of a control 
device and you choose to use the volatile organic content as a surrogate 
for the organic HAP content of coatings, you must determine the as-
purchased volatile organic content and coating solids content of each 
coating material applied by following the procedures in paragraph (d)(1) 
or (2) of this section, and the as-applied volatile organic content and 
coating solids content of each coating material by following the 
procedures in paragraph (d)(3) of this section.
    (1) Method 24. You may determine the volatile organic and coating 
solids mass fraction of each coating applied using Method 24 (40 CFR 
part 60, appendix A.) The Method 24 determination may be performed by 
the manufacturer of the material and the results provided to you. If 
these values cannot be determined using Method 24, you must submit an 
alternative technique for determining their values for approval by the 
Administrator.
    (2) Formulation data. You may determine the volatile organic content 
and coating solids content of a coating material based on formulation 
data and may rely on volatile organic content data provided by the 
manufacturer of the material. In the event of any inconsistency between 
the formulation data and the results of Method 24 of 40 CFR part 60, 
appendix A, and the Method 24 results are higher, the results of Method 
24 will govern.
    (3) As-applied volatile organic content and coating solids content. 
If the as-purchased coating material is applied to the web without any 
solvent or other material added, then the as-applied volatile organic 
content is equal to the as-purchased volatile content and the as-applied 
coating solids content is equal to the as-purchased coating solids 
content. Otherwise, the as-applied volatile organic content must be 
calculated using Equation 1b of Sec. 63.3370 and the as-applied coating 
solids content must be calculated using Equation 2 of Sec. 63.3370.
    (e) Control device efficiency. If you are using an add-on control 
device other than solvent recovery, such as an oxidizer, to comply with 
the emission standards in Sec. 63.3320, you must conduct a performance 
test to establish the destruction or removal efficiency of the control 
device according to the methods and procedures in paragraphs (e)(1) and 
(2) of this section. During the performance test, you must establish the 
operating limits required by Sec. 63.3321 according to paragraph (e)(3) 
of this section.
    (1) An initial performance test to establish the destruction or 
removal efficiency of the control device must be conducted such that 
control device inlet and outlet testing is conducted simultaneously, and 
the data are reduced in accordance with the test methods and procedures 
in paragraphs (e)(1)(i) through (ix) of this section. You must conduct 
three test runs as specified in Sec. 63.7(e)(3), and each test run must 
last at least 1 hour.
    (i) Method 1 or 1A of 40 CFR part 60, appendix A, must be used for 
sample and velocity traverses to determine sampling locations.

[[Page 480]]

    (ii) Method 2, 2A, 2C, 2D, 2F, or 2G of 40 CFR part 60, appendix A, 
must be used to determine gas volumetric flow rate.
    (iii) Method 3, 3A, or 3B of 40 CFR part 60, appendix A, must be 
used for gas analysis to determine dry molecular weight. You may also 
use as an alternative to Method 3B the manual method for measuring the 
oxygen, carbon dioxide, and carbon monoxide content of exhaust gas in 
ANSI/ASME PTC 19.10-1981, ``Flue and Exhaust Gas Analyses [Part 10, 
Instruments and Apparatus],'' (incorporated by reference, see Sec. 
63.14).
    (iv) Method 4 of 40 CFR part 60, appendix A, must be used to 
determine stack gas moisture.
    (v) The gas volumetric flow rate, dry molecular weight, and stack 
gas moisture must be determined during each test run specified in 
paragraph (f)(1)(vii) of this section.
    (vi) Method 25 or 25A of 40 CFR part 60, appendix A, must be used to 
determine total gaseous non-methane organic matter concentration. Use 
the same test method for both the inlet and outlet measurements which 
must be conducted simultaneously. You must submit notice of the intended 
test method to the Administrator for approval along with notification of 
the performance test required under Sec. 63.7(b). You must use Method 
25A if any of the conditions described in paragraphs (e)(1)(vi)(A) 
through (D) of this section apply to the control device.
    (A) The control device is not an oxidizer.
    (B) The control device is an oxidizer but an exhaust gas volatile 
organic matter concentration of 50 ppmv or less is required to comply 
with the emission standards in Sec. 63.3320; or
    (C) The control device is an oxidizer but the volatile organic 
matter concentration at the inlet to the control system and the required 
level of control are such that they result in exhaust gas volatile 
organic matter concentrations of 50 ppmv or less; or
    (D) The control device is an oxidizer but because of the high 
efficiency of the control device the anticipated volatile organic matter 
concentration at the control device exhaust is 50 ppmv or less, 
regardless of inlet concentration.
    (vii) Except as provided in Sec. 63.7(e)(3), each performance test 
must consist of three separate runs with each run conducted for at least 
1 hour under the conditions that exist when the affected source is 
operating under normal operating conditions. For the purpose of 
determining volatile organic compound concentrations and mass flow 
rates, the average of the results of all the runs will apply.
    (viii) Volatile organic matter mass flow rates must be determined 
for each run specified in paragraph (e)(1)(vii) of this section using 
Equation 1 of this section:
[GRAPHIC] [TIFF OMITTED] TR04DE02.025

Where:

Mf = Total organic volatile matter mass flow rate, kilograms 
          (kg)/hour (h).
Qsd = Volumetric flow rate of gases entering or exiting the 
          control device, as determined according to Sec. 
          63.3360(e)(1)(ii), dry standard cubic meters (dscm)/h.
Cc = Concentration of organic compounds as carbon, ppmv.
12.0 = Molecular weight of carbon.
0.0416 = Conversion factor for molar volume, kg-moles per cubic meter 
          (mol/m\3\) (@ 293 Kelvin (K) and 760 millimeters of mercury 
          (mmHg)).

    (ix) For each run, emission control device destruction or removal 
efficiency must be determined using Equation 2 of this section:
[GRAPHIC] [TIFF OMITTED] TR04DE02.026

Where:

E = Organic volatile matter control efficiency of the control device, 
          percent.
Mfi = Organic volatile matter mass flow rate at the inlet to 
          the control device, kg/h.
Mfo = Organic volatile matter mass flow rate at the outlet of 
          the control device, kg/h.

    (x) The control device destruction or removal efficiency is 
determined as the average of the efficiencies determined in the test 
runs and calculated in Equation 2 of this section.
    (2) You must record such process information as may be necessary to 
determine the conditions in existence at

[[Page 481]]

the time of the performance test. Operations during periods of startup, 
shutdown, and malfunction will not constitute representative conditions 
for the purpose of a performance test.
    (3) Operating limits. If you are using one or more add-on control 
device other than a solvent recovery system for which you conduct a 
liquid-liquid material balance to comply with the emission standards in 
Sec. 63.3320, you must establish the applicable operating limits 
required by Sec. 63.3321. These operating limits apply to each add-on 
emission control device, and you must establish the operating limits 
during the performance test required by paragraph (e) of this section 
according to the requirements in paragraphs (e)(3)(i) and (ii) of this 
section.
    (i) Thermal oxidizer. If your add-on control device is a thermal 
oxidizer, establish the operating limits according to paragraphs 
(e)(3)(i)(A) and (B) of this section.
    (A) During the performance test, you must monitor and record the 
combustion temperature at least once every 15 minutes during each of the 
three test runs. You must monitor the temperature in the firebox of the 
thermal oxidizer or immediately downstream of the firebox before any 
substantial heat exchange occurs.
    (B) Use the data collected during the performance test to calculate 
and record the average combustion temperature maintained during the 
performance test. This average combustion temperature is the minimum 
operating limit for your thermal oxidizer.
    (ii) Catalytic oxidizer. If your add-on control device is a 
catalytic oxidizer, establish the operating limits according to 
paragraphs (e)(3)(ii)(A) and (B) or paragraphs (e)(3)(ii)(C) and (D) of 
this section.
    (A) During the performance test, you must monitor and record the 
temperature just before the catalyst bed and the temperature difference 
across the catalyst bed at least once every 15 minutes during each of 
the three test runs.
    (B) Use the data collected during the performance test to calculate 
and record the average temperature just before the catalyst bed and the 
average temperature difference across the catalyst bed maintained during 
the performance test. These are the minimum operating limits for your 
catalytic oxidizer.
    (C) As an alternative to monitoring the temperature difference 
across the catalyst bed, you may monitor the temperature at the inlet to 
the catalyst bed and implement a site-specific inspection and 
maintenance plan for your catalytic oxidizer as specified in paragraph 
(e)(3)(ii)(D) of this section. During the performance test, you must 
monitor and record the temperature just before the catalyst bed at least 
once every 15 minutes during each of the three test runs. Use the data 
collected during the performance test to calculate and record the 
average temperature just before the catalyst bed during the performance 
test. This is the minimum operating limit for your catalytic oxidizer.
    (D) You must develop and implement an inspection and maintenance 
plan for your catalytic oxidizer(s) for which you elect to monitor 
according to paragraph (e)(3)(ii)(C) of this section. The plan must 
address, at a minimum, the elements specified in paragraphs 
(e)(3)(ii)(D)(1) through (3) of this section.
    (1) Annual sampling and analysis of the catalyst activity (i.e., 
conversion efficiency) following the manufacturer's or catalyst 
supplier's recommended procedures,
    (2) Monthly inspection of the oxidizer system including the burner 
assembly and fuel supply lines for problems, and
    (3) Annual internal and monthly external visual inspection of the 
catalyst bed to check for channeling, abrasion, and settling. If 
problems are found, you must take corrective action consistent with the 
manufacturer's recommendations and conduct a new performance test to 
determine destruction efficiency in accordance with this section.
    (f) Capture efficiency. If you demonstrate compliance by meeting the 
requirements of Sec. 63.3370(e), (f), (g), (h), (i)(2), (k), (n)(2) or 
(3), or (p), you must determine capture efficiency using the procedures 
in paragraph (f)(1), (2), or (3) of this section, as applicable.
    (1) You may assume your capture efficiency equals 100 percent if 
your capture system is a permanent total enclosure (PTE). You must 
confirm that

[[Page 482]]

your capture system is a PTE by demonstrating that it meets the 
requirements of section 6 of EPA Method 204 of 40 CFR part 51, appendix 
M, and that all exhaust gases from the enclosure are delivered to a 
control device.
    (2) You may determine capture efficiency according to the protocols 
for testing with temporary total enclosures that are specified in 
Methods 204 and 204A through F of 40 CFR part 51, appendix M. You may 
exclude never-controlled work stations from such capture efficiency 
determinations.
    (3) You may use any capture efficiency protocol and test methods 
that satisfy the criteria of either the Data Quality Objective or the 
Lower Confidence Limit approach as described in appendix A of subpart KK 
of this part. You may exclude never-controlled work stations from such 
capture efficiency determinations.
    (g) Volatile matter retained in the coated web or otherwise not 
emitted to the atmosphere. You may choose to take into account the mass 
of volatile matter retained in the coated web after curing or drying or 
otherwise not emitted to the atmosphere when determining compliance with 
the emission standards in Sec. 63.3320. If you choose this option, you 
must develop a testing protocol to determine the mass of volatile matter 
retained in the coated web or otherwise not emitted to the atmosphere 
and submit this protocol to the Administrator for approval. You must 
submit this protocol with your site-specific test plan under Sec. 
63.7(f). If you intend to take into account the mass of volatile matter 
retained in the coated web after curing or drying or otherwise not 
emitted to the atmosphere and demonstrate compliance according to Sec. 
63.3370(c)(3), (c)(4), (c)(5), or (d), then the test protocol you submit 
must determine the mass of organic HAP retained in the coated web or 
otherwise not emitted to the atmosphere. Otherwise, compliance must be

    (h) Control devices in series. If you use multiple control devices 
in series to comply with the emission standards in Sec. 63.3320, the 
performance test must include, at a minimum, the inlet to the first 
control device in the series, the outlet of the last control device in 
the series, and all intermediate streams (e.g., gaseous exhaust to the 
atmosphere or a liquid stream from a recovery device) that are not 
subsequently treated by any of the control devices in the series.

coating solids applied, and from a new affected source to no more than 
0.08 kg organic HAP emitted per kg coating solids applied as determined 
on a monthly average as-applied basis. If the affected source operates 
more than one capture system, more than one control device, one or more 
never-controlled work stations, or one or more intermittently-controlled 
work stations, then you must demonstrate compliance in accordance with 
the provisions of paragraph (n) of this section.

[[Page 489]]

paragraph (i) of this section when emissions from the affected source 
are controlled by a solvent recovery device or the procedure in

emissions from the affected source are controlled by a solvent recovery 
device or the procedure in paragraph (k) of this section when emissions

accordance with paragraph (l) of this section. If the affected source 
operates more than one capture system, more than one control device, one 
or more never-controlled work stations, or one or more intermittently-
controlled work stations, then you must demonstrate compliance in 
accordance with the provisions of paragraph (n) of this section.

    (m) [Reserved]
    (n) Combinations of capture and control. If you operate more than 
one capture system, more than one control device, one or more never-
controlled work stations, or one or more intermittently-controlled work 
stations, you must calculate organic HAP emissions according to the 
procedures in paragraphs (n)(1) through (4) of this section, and use the 
calculation procedures specified in paragraph (n)(5) of this section to 
convert the monitoring and other data into units of the selected control 
option in paragraphs (e) through (h) of this section. Use the procedures 
specified in paragraph (n)(6) of this section to demonstrate compliance.
    (1) Solvent recovery system using liquid-liquid material balance 
compliance demonstration. If you choose to comply by means of a liquid-
liquid material balance for each solvent recovery system used to control 
one or more web coating lines, you must determine the organic HAP 
emissions for those web coating lines controlled by that solvent 
recovery system either:
    (i) In accordance with paragraphs (i)(1)(i) through (iii) and (v) 
through (vii) of this section, if the web coating lines controlled by 
that solvent recovery system have only always-controlled work stations; 
or
    (ii) In accordance with paragraphs (i)(1)(ii), (iii), (v), and (vi) 
and (o) of this section, if the web coating lines controlled by that 
solvent recovery system have one or more never-controlled or 
intermittently-controlled work stations.
    (2) Solvent recovery system using performance test compliance 
demonstration and CEMS. To demonstrate compliance through an initial 
test of capture efficiency, continuous monitoring of a capture system 
operating parameter, and a CEMS on each solvent recovery system used to 
control one or more web coating lines, you must:
    (i) For each capture system delivering emissions to that solvent 
recovery system, monitor the operating parameter established in 
accordance with Sec. 63.3350(f) to ensure capture system efficiency; 
and
    (ii) Determine the organic HAP emissions for those web coating lines 
served by each capture system delivering emissions to that solvent 
recovery system either:
    (A) In accordance with paragraphs (i)(2)(i) through (iii), (v), 
(vi), and (viii) of this section, if the web coating lines

[[Page 496]]

served by that capture and control system have only always-controlled 
work stations; or
    (B) In accordance with paragraphs (i)(2)(i) through (iii), (vi), and 
(o) of this section, if the web coating lines served by that capture and 
control system have one or more never-controlled or intermittently-
controlled work stations.
    (3) Oxidizer. To demonstrate compliance through performance tests of 
capture efficiency and control device efficiency, continuous monitoring 
of capture system, and CPMS for control device operating parameters for 
each oxidizer used to control emissions from one or more web coating 
lines, you must:
    (i) Monitor the operating parameter in accordance with Sec. 
63.3350(e) to ensure control device efficiency; and
    (ii) For each capture system delivering emissions to that oxidizer, 
monitor the operating parameter established in accordance with Sec. 
63.3350(f) to ensure capture efficiency; and
    (iii) Determine the organic HAP emissions for those web coating 
lines served by each capture system delivering emissions to that 
oxidizer either:
    (A) In accordance with paragraphs (k)(1)(i) through (vi) of this 
section, if the web coating lines served by that capture and control 
system have only always-controlled work stations; or
    (B) In accordance with paragraphs (k)(1)(i) through (iii), (v), and 
(o) of this section, if the web coating lines served by that capture and 
control system have one or more never-controlled or intermittently-
controlled work stations.
    (4) Uncontrolled coating lines. If you own or operate one or more 
uncontrolled web coating lines, you must determine the organic HAP 
applied on those web coating lines using Equation 6 of this section. The 
organic HAP emitted from an uncontrolled web coating line is equal to 
the organic HAP applied on that web coating line.
    (5) Convert the information obtained under paragraphs (n)(1) through 
(4) of this section into the units of the selected compliance option 
using the calculation procedures specified in paragraphs (n)(5)(i) 
through (iv) of this section.

affected source for the month by summing all organic HAP emissions 
calculated according to paragraphs (n)(1), (2)(ii), (3)(iii), and (4) of 
this section.
    (ii) Coating solids applied. If demonstrating compliance on the 
basis of organic HAP emission rate based on coating solids applied or 
emission of less than the calculated allowable organic HAP, the owner or 
operator must determine the coating solids content of each coating 
material applied during the month following the procedure in Sec. 
63.3360(d).
    (iii) Organic HAP emission rate based on coating solids applied. 
Calculate the organic HAP emission rate based on coating solids applied 
for each month using Equation 9 of this section.

parameters required to be monitored under paragraphs (n)(1) through (3) 
of this section were maintained at the values established under 
Sec. Sec. 63.3350 and 63.3360; and
    (i) The total mass of organic HAP emitted by the affected source 
based on coating solids applied is no more than 0.20 kg organic HAP per 
kg coating solids applied at an existing affected source and no more 
than 0.08 kg organic HAP per kg coating solids applied at a new affected 
source; or
    (ii) The total mass of organic HAP emitted by the affected source 
based on material applied is no more than 0.04 kg organic HAP per kg 
material applied at an existing affected source and no more than 0.016

was not more than 5 percent of the total mass of organic HAP applied for 
the month at an existing affected source and no

[[Page 497]]

more than 2 percent of the total mass of organic HAP applied for the 
month at a new affected source. The total mass of organic HAP applied by 
the affected source in the month must be determined using Equation 6 of 
this section.

 Subpart KKKK_National Emission Standards for Hazardous Air Pollutants: 
                      Surface Coating of Metal Cans

    Source: 68 FR 64446, Nov. 13, 2003, unless otherwise noted.

                        What This Subpart Covers



Sec. 63.3480  What is the purpose of this subpart?

    This subpart establishes national emission standards for hazardous 
air pollutants (NESHAP) for metal can surface coating facilities. This 
subpart also establishes requirements to demonstrate initial and 
continuous compliance with the emission limitations.



Sec. 63.3481  Am I subject to this subpart?

    (a) Except as provided in paragraph (c) of this section, the source 
category to which this subpart applies is surface coating of metal cans 
and ends (including decorative tins) and metal crowns and closures. It 
includes the subcategories listed in paragraphs (a)(1) through (4) of 
this section. Surface coating is the application of coatings to a 
substrate using, for example, spray guns or dip tanks.
    (1) One- and two-piece draw and iron can body coating. The one- and 
two-piece draw and iron can body coating subcategory includes all 
coating processes involved in the manufacture of can bodies by the draw 
and iron process. This subcategory includes three distinct coating type 
segments reflecting the coatings appropriate for cans with different end 
uses. Those are two-piece beverage can body coatings, two-piece food can 
body coatings, and one-piece aerosol can body coatings.
    (2) Sheetcoating. The sheetcoating subcategory includes all of the 
flat metal sheetcoating operations associated with the manufacture of 
three-piece cans, decorative tins, crowns, and closures.
    (3) Three-piece can body assembly coating. The three-piece can body 
assembly coating subcategory includes all of the coating processes 
involved in the assembly of three-piece metal can bodies. The

    (c) An affected source is a new affected source if you commenced its 
construction after January 15, 2003 by installing new coating equipment. 
New coating equipment is equipment used to perform metal can surface 
coating at a facility where no metal can surface coating was previously 
performed and the construction is of a completely new metal can surface 
coating source where previously no metal can surface coating source had 
existed.
    (d) An affected source is reconstructed if you meet the criteria as 
defined in Sec. 63.2.
    (e) An affected source is existing if it is not new or 
reconstructed.



Sec. 63.3483  When do I have to comply with this subpart?

    The date by which you must comply with this subpart is called the 
compliance date. The compliance date for each type of affected source is 
specified in paragraphs (a) through (c) of this section. The compliance 
date begins the initial compliance period during which you conduct the 
initial compliance demonstration described in Sec. Sec. 63.3520, 
63.3530, 63.3540, and 63.3550.
    (a) For a new or reconstructed affected source, the compliance date 
is the applicable date in paragraph (a)(1) or (2) of this section.

[[Page 505]]

    (1) If the initial startup of your new or reconstructed affected 
source is before November 13, 2003, the compliance date is November 13, 
2003.
    (2) If the initial startup of your new or reconstructed affected 
source occurs after November 13, 2003, the compliance date is the date 
of initial startup of your affected source.
    (b) For an existing affected source, the compliance date is November 
13, 2006.
    (c) For an area source that increases its emissions or its potential 
to emit such that it becomes a major source of HAP emissions, the 
compliance date is specified in paragraphs (c)(1) and (2) of this 
section.
    (1) For any portion of the source that becomes a new or 
reconstructed affected source subject to this subpart, the compliance 
date is the date of initial startup of the affected source or November 
13, 2003 whichever is later.
    (2) For any portion of the source that becomes an existing affected 
source subject to this subpart, the compliance date is the date 1 year 
after the area source becomes a major source or November 13, 2006, 
whichever is later.
    (d) You must meet the notification requirements in Sec. 63.3510 
according to the dates specified in that section and in subpart A of 
this part. Some of the notifications must be submitted before the 
compliance dates described in paragraphs (a) through (c) of this 
section.

                          Emission Limitations



Sec. 63.3490  What emission limits must I meet?

    (a) For a new or reconstructed affected source, you must limit 
organic HAP emissions to the atmosphere to no more than the emission 
limit(s) in Table 1 to this subpart that apply to you during each 12-
month compliance period, determined according to the requirements in 
Sec. 63.3521, Sec. 63.3531, or Sec. 63.3541; or if you control 
emissions with an emissions control system using the control efficiency/
outlet concentration option as specified in Sec. 63.3491(d), you must 
reduce organic HAP emissions to the atmosphere to no more than the 
limit(s) in Table 3 to this subpart, determined according to the 
requirements of Sec. 63.3551. If you perform surface coating in more 
than one subcategory or utilize more than one coating type within a 
subcategory, then you must meet the individual emission limit(s) for 
each subcategory and coating type included.
    (b) For an existing affected source, you must limit organic HAP 
emissions to the atmosphere to no more than the emission limit(s) in 
Table 2 to this subpart that apply to you during each 12-month 
compliance period, determined according to the requirements in Sec. 
63.3521, Sec. 63.3531, or Sec. 63.3541; or if you control emissions 
with an emissions control system using the control efficiency/outlet 
concentration option as specified in Sec. 63.3491(d), you must reduce 
organic HAP emissions to the atmosphere to no more than the limit(s) in 
Table 3 to this subpart, determined according to the requirements of 
Sec. 63.3551. If you perform surface coating in more than one 
subcategory or utilize more than one coating type within a subcategory, 
then you must meet the individual emission limit(s) for each subcategory 
and coating type included.
    (c) If you perform surface coating in different subcategories as 
described in Sec. 63.3481(a)(1) through (4), then the coating 
operations in each subcategory constitute a separate affected source, 
and you must conduct separate compliance demonstrations for each 
applicable subcategory and coating type emission limit in paragraphs (a) 
and (b) of this section and reflect those separate determinations in 
notifications, reports, and records required by Sec. Sec. 63.3510, 
63.3511, and 63.3512, respectively.



Sec. 63.3491  What are my options for meeting the emission limits?

    You must include all coatings and thinners used in all surface 
coating operations within a subcategory or coating type segment when 
determining whether the organic HAP emission rate is equal to or less 
than the applicable emission limit in Sec. 63.3490. To make that 
determination, you must use at least one of the four compliance options 
listed in paragraphs (a) through (d) of this section. You may apply any 
of the compliance options to an individual coating operation or to 
multiple coating operations within a subcategory or coating type segment 
as a

[[Page 506]]

group. You may use different compliance options for different coating 
operations or at different times on the same coating operation. However, 
you may not use different compliance options at the same time on the 
same coating operation. If you switch between compliance options for any 
coating operation or group of coating operations, you must document that 
switch as required by Sec. 63.3512(c), and you must report it in the 
next semiannual compliance report required in Sec. 63.3511.
    (a) Compliant material option. Demonstrate that the organic HAP 
content of each coating used in the coating operation(s) is less than or 
equal to the applicable emission limit in Sec. 63.3490, and that each 
thinner used contains no organic HAP. You must meet all the requirements 
of Sec. Sec. 63.3520, 63.3521, and 63.3522 to demonstrate compliance 
with the emission limit using this option.
    (b) Emission rate without add-on controls option. Demonstrate that, 
based on the coatings and thinners used in the coating operation(s), the 
organic HAP emission rate for the coating operation(s) is less than or 
equal to the applicable emission limit in Sec. 63.3490, calculated as a 
rolling 12-month emission rate and determined on a monthly basis. You 
must meet all the requirements of Sec. Sec. 63.3530, 63.3531, and 
63.3532 to demonstrate compliance with the emission limit using this 
option.
    (c) Emission rate with add-on controls option. Demonstrate that, 
based on the coatings and thinners used in the coating operation(s) and 
the emission reductions achieved by emission capture systems and add-on 
controls, the organic HAP emission rate for the coating operation(s) is 
less than or equal to the applicable emission limit in Sec. 63.3490, 
calculated as a rolling 12-month emission rate and determined on a 
monthly basis. If you use this compliance option, you must also 
demonstrate that all emission capture systems and add-on control devices 
for the coating operation(s) used for purposes of complying with this 
subpart meet the operating limits required in Sec. 63.3492, except for 
solvent recovery systems for which you conduct liquid-liquid material 
balances according to Sec. 63.3541(i), and that you meet the work 
practice standards required in Sec. 63.3493. You must meet all the 
requirements of Sec. Sec. 63.3540 through 63.3547 to demonstrate 
compliance with the emission limits, operating limits, and work practice 
standards using this option.
    (d) Control efficiency/outlet concentration option. Demonstrate 
that, based on the emission reductions achieved by emission capture 
systems and add-on controls, total HAP emissions measured as total 
hydrocarbon (THC) are reduced by 95 percent or greater for existing 
sources, or 97 percent or greater for new or reconstructed sources, or 
that outlet THC emissions are less than or equal to 20 parts per million 
by volume, dry basis (ppmvd). If you use this compliance option, you 
must have a capture device that meets EPA Method 204 of 40 CFR part 51, 
appendix M criteria for a permanent total enclosure (PTE). You must also 
demonstrate that all emission capture systems and add-on control devices 
for the coating operation(s) used for purposes of complying with this 
subpart meet the operating limits required in Sec. 63.3492, and that 
you meet the work practice standards required in Sec. 63.3493. You must 
meet all the requirements of Sec. Sec. 63.3550 through 63.3557 to 
demonstrate compliance with the emission limits, operating limits, and 
work practice standards using this option.



Sec. 63.3492  What operating limits must I meet?

    (a) For any coating operation(s) on which you use the compliant 
material option or the emission rate without add-on controls option, you 
are not required to meet any operating limits.
    (b) For any controlled coating operation(s) on which you use the 
emission rate with add-on controls option or the control efficiency/
outlet concentration option, except those for which you use a solvent 
recovery system and conduct a liquid-liquid material balance according 
to Sec. 63.3541(i), you must meet the operating limits specified in 
Table 4 to this subpart. Those operating limits apply to the emission 
capture and control systems for the coating operation(s) used for 
purposes of complying with this subpart. You must establish the 
operating limits during the initial performance test according to the 
requirements in Sec. 63.3546 or Sec. 63.3556. New

[[Page 507]]

and reconstructed sources must meet the operating limits at all times 
after they have been established during the performance test, and 
existing sources must meet the operating limits at all times after the 
compliance date.
    (c) If you use an add-on control device other than those listed in 
Table 4 to this subpart or wish to monitor an alternative parameter and 
comply with a different operating limit, you must apply to the 
Administrator for approval of alternative monitoring under Sec. 
63.8(f).

are not required to meet any work practice standards.
    (b) If you use the emission rate with add-on controls option or the 
control efficiency/outlet concentration option to comply with the 
emission limitations, you must develop and implement a work practice 
plan to minimize organic HAP emissions from the storage, mixing, and 
conveying of coatings, thinners, and cleaning materials used in, and 
waste materials generated by, the coating operation(s) for which you use 
those options; or you must meet an alternative standard as provided in 
paragraph (c) of this section. The plan must specify practices and 
procedures to ensure that, at a minimum, the elements specified in 
paragraphs (b)(1) through (5) of this section are implemented.
    (1) All organic-HAP-containing coatings, thinners, cleaning 
materials, and waste materials must be stored in closed containers.
    (2) Spills of organic-HAP-containing coatings, thinners, cleaning 
materials, and waste materials must be minimized.
    (3) Organic-HAP-containing coatings, thinners, cleaning materials,

or 40 CFR 71.6(a)(3)(iii)(A), and the semiannual compliance report 
includes all required information concerning deviations from any 
emission limitation in this subpart, its submission will be deemed to 
satisfy any obligation to report the same deviations in the semiannual 
monitoring report. However, submission of a semiannual compliance report 
shall not otherwise affect any obligation the affected source may have 
to report deviations from permit requirements to the permitting 
authority.
    (3) General requirements. The semiannual compliance report must 
contain the information specified in paragraphs (a)(3)(i) through (v) of

        Compliance Requirements for the Compliant Material Option



Sec. 63.3520  By what date must I conduct the initial compliance 
demonstration?

    You must complete the initial compliance demonstration for the 
initial

[[Page 516]]

compliance period according to the requirements in Sec. 63.3521. The 
initial compliance period begins on the applicable compliance date 
specified in Sec. 63.3483 and ends on the last day of the 12th month 
following the compliance date. If the compliance date occurs on any day 
other than the first day of a month, then the initial compliance period 
extends through the end of that month plus the next 12 months. The 
initial compliance demonstration includes the calculations according to 
Sec. 63.3521 and supporting documentation showing that, during the 
initial compliance period, you used no coating with an organic HAP 
content that exceeded the applicable emission limit in Sec. 63.3490 and 
you used no thinners that contained organic HAP.



Sec. 63.3521  How do I demonstrate initial compliance with the
emission limitations?

    You may use the compliant material option for any individual coating 
operation, for any group of coating operations within a subcategory or 
coating type segment, or for all the coating operations within a 
subcategory or coating type segment. You must use either the emission 
rate without add-on controls option, the emission rate with add-on 
controls option, or the control efficiency/outlet concentration option 
for any coating operation in the affected source for which you do not 
use that option. To demonstrate initial compliance using the compliant 
material option, the coating operation or group of coating operations 
must use no coating with an organic HAP content that exceeds the 
applicable emission limit in Sec. 63.3490 and must use no thinner that 
contains organic HAP as determined according to this section. Any 
coating operation for which you use the compliant material option is not 
required to meet the operating limits or work practice standards 
required in Sec. Sec. 63.3492 and 63.3493, respectively. You must 
conduct a separate initial compliance demonstration for each one and 
two-piece draw and iron can body coating, sheetcoating, three-piece can 
body assembly coating, and end coating affected source. You must meet 
all the requirements of this section for the coating operation or group 
of coating operations using this option. Use the procedures in this 
section on each coating and thinner in the condition it is in when it is 
received from its manufacturer or supplier and prior to any alteration 
(e.g., mixing or thinning). Do not include any coatings or thinners used 
on coating operations for which you use the emission rate without add-on 
controls option, the emission rate with add-on controls option, or the 
control efficiency/outlet concentration option. You do not need to 
redetermine the HAP content of coatings or thinners that have been 
reclaimed onsite and reused in the coating operation(s) for which you 
use the compliant material option, provided these materials in their 
condition as received were demonstrated to comply with the compliant 
material option. All required calculations and compliance demonstrations 
may be performed with either metric or English units.
    (a) Determine the mass fraction of organic HAP for each material 
used. You must determine the mass fraction of organic HAP for each 
coating and thinner used during the compliance period by using one of 
the options in paragraphs (a)(1) through (5) of this section.
    (1) Method 311 (appendix A to 40 CFR part 63). You may use Method 
311 for determining the mass fraction of organic HAP. Use the procedures 
specified in paragraphs (a)(1)(i) and (ii) of this section when 
performing a Method 311 test.
    (i) Count each organic HAP that is measured to be present at 0.1 
percent by mass or more for Occupational Safety and Health 
Administration (OSHA)-defined carcinogens as specified in 29 CFR 
1910.1200(d)(4) and at 1.0 percent by mass or more for other compounds. 
For example, if toluene (not an OSHA carcinogen) is measured to be 0.5 
percent of the material by mass, you do not have to count it. Express 
the mass fraction of each organic HAP you count as a value truncated to 
four places after the decimal point (e.g., 0.3791).
    (ii) Calculate the total mass fraction of organic HAP in the test 
material by adding up the individual organic HAP mass fractions and 
truncating the result to three places after the decimal point (e.g., 
0.763).

[[Page 517]]

    (2) Method 24 (appendix A to 40 CFR part 60). For coatings, you may 
use Method 24 to determine the mass fraction of nonaqueous volatile 
matter and use that value as a substitute for mass fraction of organic 
HAP.
    (3) Alternative method. You may use an alternative test method for 
determining the mass fraction of organic HAP once the Administrator has 
approved it. You must follow the procedure in Sec. 63.7(f) to submit an 
alternative test method for approval.
    (4) Information from the supplier or manufacturer of the material. 
You may rely on information other than that generated by the test 
methods specified in paragraphs (a)(1) through (3) of this section, such 
as manufacturer's formulation data, if it represents each organic HAP 
that is present at 0.1 percent by mass or more for OSHA-defined 
carcinogens as specified in 29 CFR 1910.1200(d)(4) and at 1.0 percent by 
mass or more for other compounds. For example, if toluene (not an OSHA 
carcinogen) is 0.5 percent of the material by mass, you do not have to 
count it. If there is a disagreement between such information and 
results of a test conducted according to paragraphs (a)(1) through (3) 
of this section, then the test method results will take precedence 
unless, after consultation, a regulated source can demonstrate to the 
satisfaction of the enforcement agency that the formulation data are 
correct.
    (5) Solvent blends. Solvent blends may be listed as single 
components for some materials in data provided by manufacturers or 
suppliers. Solvent blends may contain organic HAP which must be counted 
toward the total organic HAP mass fraction of the materials. When test 
data and manufacturer's data for solvent blends are not available, you 
may use the default values for the mass fraction of organic HAP in those 
solvent blends listed in Table 6 or 7 to this subpart. If you use the 
tables, you must use the values in Table 6 to this subpart for all 
solvent blends that match Table 6 entries, and you may only use Table 7 
to this subpart if the solvent blends in the materials you use do not 
match any of the solvent blends in Table 6 and you only know whether the 
blend is aliphatic or aromatic. However, if the results of a Method 311 
(40 CFR part 63, appendix A) test indicate higher values than those 
listed on Table 6 or 7 to this subpart, the Method 311 results will take 
precedence.
    (b) Determine the volume fraction of coating solids for each 
coating. You must determine the volume fraction of coating solids 
(liters of coating solids per liter of coating) for each coating used 
during the compliance period by a test or by information provided by the 
supplier or the manufacturer of the material as specified in paragraphs 
(b)(1) and (2) of this section. If test results obtained according to 
paragraph (b)(1) of this section do not agree with the information 
obtained under paragraph (b)(2) of this section, the test results will 
take precedence.
    (1) ASTM Method D2697-86 (Reapproved 1998) or D6093-97. You may use 
ASTM Method D2697-86 (Reapproved 1998), ``Standard Test Method for 
Volume Nonvolatile Matter in Clear or Pigmented Coatings'' (incorporated 
by reference, see Sec. 63.14), or D6093-97, ``Standard Test Method for 
Percent Volume Nonvolatile Matter in Clear or Pigmented Coatings Using a 
Helium Gas Pycnometer'' (incorporated by reference, see Sec. 63.14), to 
determine the volume fraction of coating solids for each coating. Divide 
the nonvolatile volume percent obtained with the methods by 100 to 
calculate volume fraction of coating solids. If these values cannot be 
determined using these methods, the owner/operator may submit an 
alternative technique for determining the values for approval by the 
Administrator.
    (2) Information from the supplier or manufacturer of the material. 
You may obtain the volume fraction of coating solids for each coating 
from the supplier or manufacturer.
    (c) Determine the density of each coating. Determine the density of 
each coating used during the compliance period from test results using 
ASTM Method D1475-90 or information from the supplier or manufacturer of 
the material. If there is disagreement between ASTM Method D1475-90 test 
results and the supplier's or manufacturer's information, the test 
results will take precedence.
    (d) Calculate the organic HAP content of each coating. Calculate the 
organic

[[Page 518]]

HAP content, kg organic HAP per liter coating solids, of each coating 
used during the compliance period, using Equation 1 of this section.
[GRAPHIC] [TIFF OMITTED] TR13NO03.000

Where:

Hc = Organic HAP content of the coating, kg organic HAP per 
          liter coating solids.
Dc = Density of coating, kg coating per liter coating, 
          determined according to paragraph (c) of this section.
Wc = mass fraction of organic HAP in the coating, kg organic 
          HAP per kg coating, determined according to paragraph (a) of 
          this section.
Vs = Volume fraction of coating solids, liter coating solids 
          per liter coating, determined according to paragraph (b) of 
          this section.

    (e) Compliance demonstration. The organic HAP content for each 
coating used during the initial compliance period, determined using 
Equation 1 of this section, must be less than or equal to the applicable 
emission limit in Sec. 63.3490 and each thinner used during the initial 
compliance period must contain no organic HAP, determined according to 
paragraph (a) of this section. You must keep all records required by 
Sec. Sec. 63.3512 and 63.3513. As part of the Notification of 
Compliance Status required in Sec. 63.3510, you must identify the 
coating operation(s) for which you used the compliant material option 
and submit a statement that the coating operation(s) was (were) in 
compliance with the emission limitations during the initial compliance 
period because you used no coatings for which the organic HAP content 
exceeded the applicable emission limit in Sec. 63.3490, and you used no 
thinners that contained organic HAP, determined according to paragraph 
(a) of this section.

[68 FR 64446, Nov. 13, 2003, as amended at 71 FR 1383, Jan. 6, 2006]



Sec. 63.3522  How do I demonstrate continuous compliance with the 
emission limitations?

    (a) For each compliance period, to demonstrate continuous 
compliance, you must use no coating for which the organic HAP content, 
determined using Equation 1 of Sec. 63.3521, exceeds the applicable 
emission limit in Sec. 63.3490 and use no thinner that contains organic 
HAP, determined according to Sec. 63.3521(a). A compliance period 
consists of 12 months. Each month after the end of the initial 
compliance period described in Sec. 63.3520 is the end of a compliance 
period consisting of that month and the preceding 11 months.
    (b) If you choose to comply with the emission limitations by using 
the compliant material option, the use of any coating or thinner that 
does not meet the criteria specified in paragraph (a) of this section is 
a deviation from the emission limitations that must be reported as 
specified in Sec. Sec. 63.3510(b)(6) and 63.3511(a)(5).
    (c) As part of each semiannual compliance report required by Sec. 
63.3511, you must identify the coating operation(s) for which you used 
the compliant material option. If there were no deviations from the 
emission limitations set forth in Sec. 63.3490, submit a statement that 
the coating operation(s) was (were) in compliance with the emission 
limitations during the reporting period because you used no coating for 
which the organic HAP content exceeded the applicable emission limit in 
Sec. 63.3490, and you used no thinner that contained organic HAP, as 
determined according to Sec. 63.3521(a).
    (d) You must maintain records as specified in Sec. Sec. 63.3512 and 
63.3513.

 Compliance Requirements for the Emission Rate Without Add-On Controls 
                                 Option



Sec. 63.3530  By what date must I conduct the initial compliance
demonstration?

    You must complete the initial compliance demonstration for the 
initial compliance period according to the requirements of Sec. 
63.3531. The initial compliance period begins on the applicable 
compliance date specified in Sec. 63.3483 and ends on the last day of 
the 12th month following the compliance date. If the compliance date 
occurs on any day other than the first day of a month, then the initial 
compliance period extends through the end of that month plus the next 12 
months. You

[[Page 519]]

must determine the mass of organic HAP emissions and volume of coating 
solids used each month and then calculate a 12-month organic HAP 
emission rate at the end of the initial 12-month compliance period. The 
initial compliance demonstration includes the calculations according to 
Sec. 63.3531 and supporting documentation showing that, during the 
initial compliance period, the organic HAP emission rate was equal to or 
less than the applicable emission limit in Sec. 63.3490.



Sec. 63.3531  How do I demonstrate initial compliance with the
emission limitations?

    You may use the emission rate without add-on controls option for any 
coating operation, for any group of coating operations within a 
subcategory or coating type segment, or for all of the coating 
operations within a subcategory or coating type segment. You must use 
either the compliant material option, the emission rate with add-on 
controls option, or the control efficiency/outlet concentration option 
for any coating operation in the affected source for which you do not 
use this option. If you use the alternative overall emission limit for a 
subcategory according to paragraph (i) of this section to demonstrate 
compliance, however, you must include all coating operations in all 
coating type segments in the subcategory to determine compliance with 
the overall limit. To demonstrate initial compliance using the emission 
rate without add-on controls option, the coating operation or group of 
coating operations must meet the applicable emission limit in Sec. 
63.3490, but is not required to meet the operating limits or work 
practice standards in Sec. Sec. 63.3492 and 63.3493, respectively. You 
must conduct a separate initial compliance demonstration for each one 
and two-piece draw and iron can body coating, sheetcoating, three-piece 
can body assembly coating, and end coating affected source. You must 
meet all the requirements of this section to demonstrate initial 
compliance with the applicable emission limit in Sec. 63.3490 for the 
coating operation(s). When calculating the organic HAP emission rate 
according to this section, do not include any coatings or thinners used 
on coating operations for which you use the compliant material option, 
the emission rate with add-on controls option, or the control 
efficiency/outlet concentration option or coating operations in a 
different affected source in a different subcategory. Use the procedures 
in this section on each coating and thinner in the condition it is in 
when it is received from its manufacturer or supplier and prior to any 
alteration (e.g., mixing or thinning). You do not need to redetermine 
the mass of organic HAP in coatings or thinners that have been reclaimed 
onsite and reused in the coating operation(s) for which you use the 
emission rate without add-on controls option. All required calculations 
and compliance demonstrations may be performed with either metric or 
English units.
    (a) Determine the mass fraction of organic HAP for each material. 
Determine the mass fraction of organic HAP for each coating and thinner 
used during each month according to the requirements in Sec. 
63.3521(a).
    (b) Determine the volume fraction of coating solids for each 
coating. Determine the volume fraction of coating solids for each 
coating used during each month according to the requirements in Sec. 
63.3521(b).
    (c) Determine the density of each material. Determine the density of 
each coating and thinner used during each month from test results using 
ASTM Method D1475-90, information from the supplier or manufacturer of 
the material, or reference sources providing density or specific gravity 
data for pure materials. If there is disagreement between ASTM Method 
D1475-90 test results and such other information sources, the test 
results will take precedence.
    (d) Determine the volume of each material used. Determine the volume 
(liters) of each coating and thinner used during each month by 
measurement or usage records.
    (e) Calculate the mass of organic HAP emissions. The mass of organic 
HAP emissions is the combined mass of organic HAP contained in all 
coatings and thinners used during each month minus the organic HAP in 
certain

in waste materials sent or designated for shipment to a hazardous waste 
TSDF or other applicable waste management location in Equation 1 of this 
section, then you must determine it according to paragraphs (e)(3)(i) 
through (iv) of this section.
    (i) You may include in the determination only waste materials that 
are generated by coating operations for which you use Equation 1 of this 
section and that will be treated or disposed of by a facility regulated 
as a TSDF under 40 CFR part 262, 264, 265, or 266 or otherwise managed 
in accordance with applicable Federal and State waste management 
regulations. The TSDF or other applicable waste management location may 
be either offsite or onsite. You may not include organic HAP contained 
in wastewater.
    (ii) You must determine either the amount of the waste materials 
sent to a TSDF, or other applicable waste management location, during 
the month, or the amount collected and stored during the month and 
designated for future transport to a TSDF or other applicable waste 
management location. Do not include in your determination any waste 
materials sent to a TSDF or other applicable waste management location 
during a month if

[[Page 521]]

you have already included them in the amount collected and stored during 
that month or a previous month.
    (iii) Determine the total mass of organic HAP contained in the waste 
materials specified in paragraph (e)(3)(ii) of this section.
    (iv) You must document the methodology you used to determine the 
amount of waste materials and the total mass of organic HAP they contain 
as required in Sec. 63.3512(h). To the extent that waste manifests 
include this information, they may be used as part of the documentation 
of the amount of waste materials and mass of organic HAP contained in 
them.
    (f) Calculate the total volume of coating solids used. Determine the 
total volume of coating solids used which is the combined volume of 
coating solids for all the coatings used during each month using 
Equation 2 of this section.
[GRAPHIC] [TIFF OMITTED] TR13NO03.004

Where:

Vst = Total volume of coating solids used during the month, 
          liters.
Volc,i = Total volume of coating, i, used during the month, 
          liters.
Vs,i = Volume fraction of coating solids for coating, i, 
          liter solids per liter coating, determined according to Sec. 
          63.3521(b).

    (g) Calculate the organic HAP emission rate. Calculate the organic 
HAP emission rate for the 12-month compliance period, kg organic HAP per 
liter coating solids used, using Equation 3 of this section.
[GRAPHIC] [TIFF OMITTED] TR13NO03.005

Where:

Hyr = Organic HAP emission rate for the 12-month compliance 
          period, kg organic HAP per liter coating solids.
He = Total mass of organic HAP emissions, kg, from all

          month, y, as calculated by Equation 2 of this section.
y = Identifier for months.

    (h) Compliance demonstration. The organic HAP emission rate for the 
initial 12-month compliance period, Hyr, must be less than or 
equal to the applicable emission limit in Sec. 63.3490. You must keep 
all records as required by Sec. Sec. 63.3512 and 63.3513. As part of 
the Notification of Compliance Status required by Sec. 63.3510, you 
must identify the coating operation(s) for which you used the emission 
rate without add-on controls option and submit a statement that the 
coating operation(s) was (were) in compliance with the emission 
limitations during the initial compliance period because the organic HAP 
emission rate was less than or equal to the applicable emission limit in 
Sec. 63.3490, determined according to this section.
    (i) Alternative calculation of overall subcategory emission limit 
(OSEL). Alternatively, if your affected source applies coatings in more 
than one coating type segment within a subcategory, you may calculate an 
overall HAP emission limit for the subcategory using Equation 4 of this 
section. If you use this approach, you must limit organic HAP emissions 
to the atmosphere to the OSEL specified by Equation 4 of this section 
during each 12-month compliance period.
[GRAPHIC] [TIFF OMITTED] TR13NO03.006

Where:

OSEL = Total allowable organic HAP in kg HAP/liter coating solids (pound 
          (lb) HAP/gal solids) that can be emitted to the atmosphere 
          from all coating type segments in the subcategory.
Li = HAP emission limit for coating type segment i from Table

          source, kg HAP/liter coating solids (lb HAP/gal solids).
Vi = Total volume of coating solids in liters (gal) for all 
          coatings in coating type segment i used during the 12-month 
          compliance period.

[[Page 522]]

n = Number of coating type segments within one subcategory being used at 
          the affected source.

    You must use the OSEL determined by Equation 4 of this section 
throughout the 12-month compliance period and may not switch between 
compliance with individual coating type limits and an OSEL. You may not 
include coatings in different subcategories in determining your OSEL by 
this approach. You must keep all records as required by Sec. Sec. 
63.3512 and 63.3513. As part of the Notification of Compliance Status 
required by Sec. 63.3510, you must identify the subcategory for which 
you used a calculated OSEL and submit a statement that the coating 
operation(s) was (were) in compliance with the emission limitations 
during the initial compliance period because the organic HAP emission 
rate for the subcategory was less than or equal to the OSEL determined 
according to this section.

[68 FR 64446, Nov. 13, 2003, as amended at 71 FR 1384, Jan. 6, 2006]



Sec. 63.3532  How do I demonstrate continuous compliance with the
emission limitations?

    (a) To demonstrate continuous compliance, the organic HAP emission 
rate for each compliance period, determined according to Sec. 
63.3531(a) through (g), must be less than or equal to the applicable 
emission limit in Sec. 63.3490. Alternatively, if you calculate an OSEL 
for all coating type segments within a subcategory according to Sec. 
63.3531(i), the organic HAP emission rate for the subcategory for each 
compliance period must be less than or equal to the calculated OSEL. You 
must use the calculated OSEL throughout each compliance period. A 
compliance period consists of 12 months. Each month after the end of the 
initial compliance period described in Sec. 63.3530 is the end of a 
compliance period consisting of that month and the preceding 11 months. 
You must perform the calculations in Sec. 63.3531(a) through (g) on a 
monthly basis using data from the previous 12 months of operation.
    (b) If the organic HAP emission rate for any 12-month compliance 
period exceeded the applicable emission limit in Sec. 63.3490 or the 
OSEL calculated according to Sec. 63.3531(i), this is a deviation from 
the emission limitations for that compliance period and must be reported 
as specified in Sec. Sec. 63.3510(c)(6) and 63.3511(a)(6).
    (c) As part of each semiannual compliance report required by Sec. 
63.3511, you must identify the coating operation(s) for which you used 
the emission rate without add-on controls option. If there were no 
deviations from the emission limitations, you must submit a statement 
that the coating operation(s) was (were) in compliance with the emission 
limitations during the reporting period because the organic HAP emission 
rate for each compliance period was less than or equal to the applicable 
emission limit in Sec. 63.3490 determined according to Sec. 63.3531(a) 
through (g), or using the OSEL calculated according to Sec. 63.3531(i).
    (d) You must maintain records as specified in Sec. Sec. 63.3512 and 
63.3513.

   Compliance Requirements for the Emission Rate With Add-On Controls 
                                 Option



Sec. 63.3540  By what date must I conduct performance tests and 
other initial compliance demonstrations?

    (a) New and reconstructed affected sources. For a new or 
reconstructed affected source, you must meet the requirements of 
paragraphs (a)(1) through (4) of this section.
    (1) All emission capture systems, add-on control devices, and CPMS 
must be installed and operating no later than the applicable compliance 
date specified in Sec. 63.3483. Except for solvent recovery systems for 
which you conduct liquid-liquid material balances according to Sec. 
63.3541(i), you must conduct a performance test of each capture system 
and add-on control device according to Sec. Sec. 63.3543, 63.3544, and 
63.3545 and establish the operating limits required by Sec. 63.3492 no 
later than 180 days after the applicable compliance date specified in 
Sec. 63.3483. For a solvent recovery system for which you conduct 
liquid-liquid material balances according to Sec. 63.3541(i), you must 
initiate the first material balance no later than the applicable 
compliance date specified in Sec. 63.3483.

63.3541. The initial compliance period begins on the applicable 
compliance date specified in Sec. 63.3483 and ends on the last day of 
the 12th month following the compliance date. If the compliance date 
occurs on any day other than the first day of a month, then the initial 
compliance period extends through the end of that month plus the next 12 
months. You must determine the mass of organic HAP emissions and volume 
of coating solids used each month and then calculate a 12-month organic 
HAP emission rate at the end of the initial 12-month compliance period. 
The initial compliance demonstration includes the results of emission 
capture system and add-on control device performance tests conducted 
according to Sec. Sec. 63.3543, 63.3544, and 63.3545; results of 
liquid-liquid material balances conducted according to Sec. 63.3541(i);

showing that, during the initial compliance period, the organic HAP 
emission rate was equal to or less than the emission limit in Sec. 
63.3490(a); the operating limits established during the performance 
tests and the results of the continuous parameter monitoring required by 
Sec. 63.3547; and documentation of whether you developed and 
implemented the work practice plan required by Sec. 63.3493.
    (4) You do not need to comply with the operating limits for the 
emission capture system and add-on control device required by Sec. 
63.3492 until after you have completed the performance tests specified 
in paragraph (a)(1) of this section. Instead, you must maintain a log 
detailing the operation and maintenance of the emission capture system, 
add-on control device, and continuous parameter monitors during the 
period between the compliance date and the performance test. You must 
begin complying with the operating limits for your affected source on 
the date you complete the performance tests specified in paragraph

apply to solvent recovery systems for which you conduct liquid-liquid 
material balances according to the requirements in Sec. 63.3541(i).
    (b) Existing affected sources. For an existing affected source, you 
must meet the requirements of paragraphs (b)(1) through (3) of this 
section.
    (1) All emission capture systems, add-on control devices, and CPMS 
must be installed and operating no later than the applicable compliance 
date specified in Sec. 63.3483. Except for solvent recovery systems for 
which you conduct liquid-liquid material balances according to Sec. 
63.3541(i), you must conduct a performance test of each capture system 
and add-on control device according to the procedures in Sec. Sec. 
63.3543, 63.3544, and 63.3545 and establish the operating limits 
required by Sec. 63.3492 no later than the compliance date specified in 
Sec. 63.3483. For a solvent recovery system for which you conduct 
liquid-liquid material balances according to Sec. 63.3541(i), you must 
initiate the first material balance no later than the compliance date 
specified in Sec. 63.3483.
    (2) You must develop and begin implementing the work practice plan

Sec. 63.3483.
    (3) You must complete the initial compliance demonstration for the 
initial compliance period according to the requirements of Sec. 
63.3541. The initial compliance period begins on the applicable 
compliance date specified in Sec. 63.3483 and ends on the last day of 
the 12th month following the compliance date. If the compliance date 
occurs on any day other than the first day of a month, then the initial 
compliance period extends through the end of that month plus the next 12 
months. You must determine the mass of organic HAP emissions and volume 
of coating solids used each month and then calculate a 12-month organic 
HAP emission rate at the end of the initial 12-month compliance period. 
The initial compliance demonstration includes the results of emission 
capture system and add-on control device performance tests conducted 
according to Sec. Sec. 63.3543,

conducted according to Sec. 63.3541(i); calculations according to Sec. 
63.3541 and supporting documentation showing that during the initial 
compliance period the organic HAP emission rate was equal to or less 
than the emission limit in Sec. 63.3490(b); the operating limits 
established during the performance tests and the results of the 
continuous parameter monitoring required by Sec. 63.3547; and 
documentation of whether you developed and implemented the work practice 
plan required by Sec. 63.3493.



Sec. 63.3541  How do I demonstrate initial compliance?

    (a) You may use the emission rate with add-on controls option for 
any coating operation, for any group of coating operations within a 
subcategory or coating type segment, or for all of the coating 
operations within a subcategory or coating type segment. You may include 
both controlled and uncontrolled coating operations in a group for which 
you use this option. You must use either the compliant material option, 
the emission rate without add-on controls option, or the control 
efficiency/outlet concentration option for any coating operation in the 
affected source for which you do not use the emission rate with add-on 
controls option. To demonstrate initial compliance, the coating 
operation(s) for which you use the emission rate with add-on controls 
option must meet the applicable emission limitations in Sec. 63.3490. 
You must conduct a separate initial compliance demonstration for each 
one and two-piece draw and iron can body coating, sheetcoating, three-
piece can body assembly coating, and end coating affected source. You 
must meet all the requirements of this section to demonstrate initial 
compliance with the emission limitations. When calculating the organic 
HAP emission rate according to this section, do not include any coatings 
or thinners used on coating operations for which you use the compliant 
material option, the emission rate without add-on controls option, or 
the control efficiency/outlet concentration option. You do not need to 
redetermine the mass of organic HAP in coatings or thinners that have 
been reclaimed onsite and reused in the coating operation(s) for which 
you use the emission rate with add-on controls option. All required 
calculations and compliance demonstrations may be performed with either 
metric or English units.
    (b) Compliance with operating limits. Except as provided in Sec. 
63.3540(a)(4) and except for solvent recovery systems for which you 
conduct liquid-liquid material balances according to the requirements of 
Sec. 63.3541(i), you must establish and demonstrate continuous 
compliance during the initial compliance period with the operating 
limits required by Sec. 63.3492 using the procedures specified in 
Sec. Sec. 63.3546 and 63.3547.
    (c) Compliance with work practice requirements. You must develop, 
implement, and document your implementation of the work practice plan 
required by Sec. 63.3493 during the initial compliance period, as 
specified in Sec. 63.3512.
    (d) Compliance with emission limits. You must follow the procedures 
in paragraphs (e) through (n) of this section to demonstrate compliance 
with the applicable emission limit in Sec. 63.3490.
    (e) Determine the mass fraction of organic HAP, density, volume 
used, and volume fraction of coating solids. Follow the procedures 
specified in Sec. 63.3531(a) through (d) to determine the mass fraction 
of organic HAP, density, and volume of each coating and thinner used 
during each month and the volume fraction of coating solids for each 
coating used during each month.
    (f) Calculate the total mass of organic HAP emissions before add-on 
controls. Using Equation 1 of Sec. 63.3531, calculate the total mass of 
organic HAP emissions before add-on controls from all coatings and 
thinners used during each month in the coating operation or group of 
coating operations for which you use the emission rate with add-on 
controls option.
    (g) Calculate the organic HAP emission reduction for each controlled 
coating operation. Determine the mass of organic HAP emissions reduced 
for each controlled coating operation during each month. The emission 
reduction determination quantifies the total organic HAP emissions that 
pass through the

[[Page 525]]

emission capture system and are destroyed or removed by the add-on 
control device. Use the procedures in paragraph (h) of this section to 
calculate the mass of organic HAP emission reduction for each controlled 
coating operation using an emission capture system and add-on control 
device other than a solvent recovery system for which you conduct 
liquid-liquid material balances. For each controlled coating operation 
using a solvent recovery system for which you conduct a liquid-liquid 
material balance, use the procedures in paragraph (j) of this section to 
calculate the organic HAP emission reduction.
    (h) Calculate the organic HAP emission reduction for each controlled 
coating operation not using liquid-liquid material balances. For each 
controlled coating operation using an emission capture system and add-on 
control device, other than a solvent recovery system for which you 
conduct liquid-liquid material balances, calculate the organic HAP 
emission reduction, using Equation 1 of this section. The calculation 
applies the emission capture system efficiency and add-on control device 
efficiency to the mass of organic HAP contained in the coatings and 
thinners that are used in the coating operation served by the emission 
capture system and add-on control device during each month. For any 
period of time a deviation specified in Sec. 63.3542(c) or (d) occurs 
in the controlled coating operation, including a deviation during a 
period of SSM, you must assume zero efficiency for the emission capture 
system and add-on control device, unless you have other data indicating 
the actual efficiency of the emission capture system and add-on control 
device, and the use of these data has been approved by the 
Administrator. Equation 1 of this section treats the materials used 
during such a deviation as if they were used on an uncontrolled coating 
operation for the time period of the deviation.

    (m) Compliance demonstration. To demonstrate initial compliance with 
the emission limit, the organic HAP emission rate, calculated using 
Equation 5 of this section, must be less than or equal to the applicable 
emission limit in Sec. 63.3490. You must keep all records as required 
by Sec. Sec. 63.3512 and 63.3513. As part of the Notification of 
Compliance Status required by Sec. 63.3510, you must identify the 
coating operation(s) for which you used the emission rate with add-on 
controls option and submit a statement that the coating operation(s) was 
in compliance with the emission limitations during the initial 
compliance period because the organic HAP emission rate was less than or 
equal to the applicable emission limit in Sec. 63.3490, and you 
achieved the operating limits required by Sec. 63.3492 and the work

    (n) Alternative calculation of overall subcategory emission limit. 
Alternatively, if your affected source applies coatings in more than one

to the atmosphere to the OSEL specified by Equation 4 of Sec. 63.3531 
during each 12-month compliance period. You must use the OSEL determined 
by Equation 4 of Sec. 63.3531 throughout the 12-month compliance period 
and may not switch between compliance with individual coating type 
limits and an OSEL. If you follow this approach, you may not include 
coatings in different subcategories in determining your OSEL. You must 
keep all records as required by Sec. Sec. 63.3512 and 63.3513. As part 
of the Notification of Compliance Status required by Sec. 63.3510, you 
must identify the subcategory for which you used a calculated OSEL and 
submit a statement that the coating operation(s) was in compliance with 
the emission limitations during the initial compliance period because 
the organic HAP emission rate for the subcategory was less than or equal 
to the OSEL determined according to this section.

[68 FR 64446, Nov. 13, 2003, as amended at 71 FR 1384, Jan. 6, 2006]



Sec. 63.3542  How do I demonstrate continuous compliance with the
emission limitations?

    (a) To demonstrate continuous compliance with the applicable 
emission limit in Sec. 63.3490, the organic HAP emission rate for each 
compliance period, determined according to the procedures in Sec. 
63.3541, must be equal to or less than the applicable emission limit in 
Sec. 63.3490. Alternatively, if you calculate an OSEL for all coating 
type segments within a subcategory according to Sec. 63.3531(i), the 
organic HAP emission rate for the subcategory for each compliance period 
must be less than or equal to the calculated OSEL.

[[Page 530]]

You must use the calculated OSEL throughout each compliance period. A 
compliance period consists of 12 months. Each month after the end of the 
initial compliance period described in Sec. 63.3540 is the end of a 
compliance period consisting of that month and the preceding 11 months. 
You must perform the calculations in Sec. 63.3541 on a monthly basis 
using data from the previous 12 months of operation.
    (b) If the organic HAP emission rate for any 12-month compliance 
period exceeded the applicable emission limit in Sec. 63.3490, that is 
a deviation from the emission limitation for that compliance period and 
must be reported as specified in Sec. Sec. 63.3510(b)(6) and 
63.3511(a)(7).
    (c) You must demonstrate continuous compliance with each operating 
limit required by Sec. 63.3492 that applies to you as specified in 
Table 4 to this subpart.
    (1) If an operating parameter is out of the allowed range specified 
in Table 4 to this subpart, this is a deviation from the operating limit 
that must be reported as specified in Sec. Sec. 63.3510(b)(6) and 
63.3511(a)(7).
    (2) If an operating parameter deviates from the operating limit 
specified in Table 4 to this subpart, then you must assume that the 
emission capture system and add-on control device were achieving zero 
efficiency during the time period of the deviation, unless you have 
other data indicating the actual efficiency of the emission capture 
system and add-on control device, and the use of these data has been 
approved by the Administrator. For the purposes of completing the 
compliance calculations specified in Sec. 63.3541(h), you must treat 
the materials used during a deviation on a controlled coating operation 
as if they were used on an uncontrolled coating operation for the time 
period of the deviation as indicated in Equation 1 of Sec. 63.3541.
    (d) You must meet the requirements for bypass lines in Sec. 
63.3547(b) for controlled coating operations for which you do not 
conduct liquid-liquid material balances. If any bypass line is opened 
and emissions are diverted to the atmosphere when the coating operation 
is running, this is a deviation that must be reported as specified in 
Sec. Sec. 63.3510(b)(6) and 63.3511(a)(7). For the purposes of 
completing the compliance calculations specified in Sec. 63.3541(h), 
you must treat the materials used during a deviation on a controlled 
coating operation as if they were used on an uncontrolled coating 
operation for the time period of the deviation as indicated in Equation 
1 of Sec. 63.3541.
    (e) You must demonstrate continuous compliance with the work 
practice standards in Sec. 63.3493. If you did not develop a work 
practice plan or you did not implement the plan or you did not keep the 
records required by Sec. 63.3512(j)(8), that is a deviation from the 
work practice standards that must be reported as specified in Sec. Sec. 
63.3510(b)(6) and 63.3511(a)(7).
    (f) As part of each semiannual compliance report required in Sec. 
63.3511, you must identify the coating operation(s) for which you used 
the emission rate with add-on controls option. If there were no 
deviations from the emission limitations, submit a statement that you 
were in compliance with the emission limitations during the reporting 
period because the organic HAP emission rate for each compliance period 
was less than or equal to the applicable emission limit in Sec. 
63.3490, and you achieved the operating limits required by Sec. 63.3492 
and the work practice standards required by Sec. 63.3493 during each 
compliance period.
    (g) [Reserved]
    (h) Consistent with Sec. Sec. 63.6(e) and 63.7(e)(1), deviations 
that occur during a period of startup, shutdown, or malfunction of the 
emission capture system, add-on control device, or coating operation 
that may affect emission capture or control device efficiency are not 
violations if you demonstrate to the Administrator's satisfaction that 
you were operating in accordance with Sec. 63.6(e)(1). The 
Administrator will determine whether deviations that occur during a 
period you identify as a startup, shutdown, or malfunction are 
violations according to the provisions in Sec. 63.6(e).
    (i) You must maintain records as specified in Sec. Sec. 63.3512 and 
63.3513.

Sec. 63.3543  What are the general requirements for performance tests?

    (a) You must conduct each performance test required by Sec. 63.3540 
according to the requirements in Sec. 63.7(e)(1) and under the 
conditions in this section unless you obtain a waiver of the performance 
test according to the provisions in Sec. 63.7(h).
    (1) Representative coating operation operating conditions. You must 
conduct the performance test under representative operating conditions 
for the coating operation. Operations during periods of startup, 
shutdown, or malfunction and during periods of nonoperation do not 
constitute representative conditions. You must record the process 
information that is necessary to document operating conditions during 
the test and explain why the conditions represent normal operation.
    (2) Representative emission capture system and add-on control device 
operating conditions. You must conduct the performance test when the 
emission capture system and add-on control device are operating at a 
representative flow rate and the add-on control device is operating at a 
representative inlet concentration. You must record information that is 
necessary to document emission capture system and add-on control device 
operating conditions during the test and explain why the conditions 
represent normal operation.
    (b) You must conduct each performance test of an emission capture 
system according to the requirements in Sec. 63.3544. You must conduct 
each performance test of an add-on control device according to the 
requirements in Sec. 63.3545.



Sec. 63.3544  How do I determine the emission capture system efficiency?

    You must use the procedures and test methods in this section to 
determine capture efficiency as part of the performance test required by 
Sec. 63.3540.
    (a) Assuming 100 percent capture efficiency. You may assume the 
capture system efficiency is 100 percent if both of the conditions in 
paragraphs (a)(1) and (2) of this section are met:
    (1) The capture system meets the criteria in Method 204 of appendix 
M to 40 CFR part 51 for a PTE and directs all the exhaust gases from the 
enclosure to an add-on control device.
    (2) All coatings and thinners used in the coating operation are 
applied within the capture system, and coating solvent flash-off, 
curing, and drying occurs within the capture system. For example, the 
criterion is not met if parts enter the open shop environment when being 
moved between a spray booth and a curing oven.
    (b) Measuring capture efficiency. If the capture system does not 
meet both of the criteria in paragraphs (a)(1) and (2) of this section, 
then you must use one of the three protocols described in paragraphs 
(c), (d), and (e) of this section to measure capture efficiency. The 
capture efficiency measurements use TVH capture efficiency as a 
surrogate for organic HAP capture efficiency. For the protocols in 
paragraphs (c) and (d) of this section, the capture efficiency 
measurement must consist of three test runs. Each test run must be at 
least 3 hours duration or the length of a production run, whichever is 
longer, up to 8 hours. For the purposes of this test, a production run 
means the time required for a single part to go from the beginning to 
the end of production, and includes drying or curing time, but excludes 
surface preparation activities.
    (c) Liquid-to-uncaptured-gas protocol using a temporary total 
enclosure or building enclosure. The liquid-to-uncaptured-gas protocol 
compares the mass of liquid TVH in materials used in the coating 
operation to the mass of TVH emissions not captured by the emission 
capture system. Use a TTE or a building enclosure and the procedures in 
paragraphs (c)(1) through (6) of this section to measure emission 
capture system efficiency using the liquid-to-uncaptured-gas protocol.
    (1) Either use a building enclosure or construct an enclosure around 
the coating operation where coatings and thinners are applied and all 
areas where emissions from these applied coatings and materials 
subsequently occur, such as flash-off, curing, and drying areas. The 
areas of the coating operation where capture devices collect emissions 
for routing to an add-on control device, such as the entrance and exit 
areas of an oven or spray booth, must also be inside the enclosure. The

[[Page 532]]

enclosure must meet the applicable definition of a TTE or building 
enclosure in Method 204 of appendix M to 40 CFR part 51.
    (2) Use Method 204A or 204F of appendix M to 40 CFR part 51 to 
determine the mass fraction of TVH liquid input from each coating and 
thinner used in the coating operation during each capture efficiency 
test run. To make the determination, substitute TVH for each occurrence 
of the term volatile organic compounds (VOC) in the methods.
    (3) Use Equation 1 of this section to calculate the total mass of 
TVH liquid input from all the coatings and thinners used in the coating 
operation during each capture efficiency test run.

Where:

TVHused = Total mass of liquid TVH in materials used in the 
          coating operation during the capture efficiency test run, kg.
TVHi = Mass fraction of TVH in coating or thinner, i, that is 
          used in the coating operation during the capture efficiency 
          test run, kg TVH per kg material.

          material.
n = Number of different coatings and thinners used in the coating 
          operation during the capture efficiency test run.

    (4) Use Method 204D or 204E of appendix M to 40 CFR part 51 to 
measure the total mass, kg, of TVH emissions that are not captured by 
the emission capture system; they are measured as they exit the TTE or 
building enclosure during each capture efficiency test run. To make the 
measurement, substitute TVH for each occurrence of the term VOC in the 
methods.
    (i) Use Method 204D of appendix M to 40 CFR part 51 if the enclosure 
is a TTE.
    (ii) Use Method 204E of appendix M to 40 CFR part 51 if the 
enclosure is a building enclosure. During the capture efficiency 
measurement, all organic compound emitting operations inside the 
building enclosure other than the coating operation for which capture 
efficiency is being determined must be shut down but all fans and 
blowers must be operating normally.
    (5) For each capture efficiency test run, determine the percent 
capture efficiency of the emission capture system using Equation 2 of 
this section.
[GRAPHIC] [TIFF OMITTED] TR13NO03.019

Where:

CE = Capture efficiency of the emission capture system vented to the 
          add-on control device, percent.
TVHused = Total mass of liquid TVH used in the coating 
          operation during the capture efficiency test run, kg.
TVHuncaptured = Total mass of TVH that is not captured by the 
          emission capture system and that exits from the TTE or 
          building enclosure during the capture efficiency test run, kg, 
          determined according to paragraph (c)(4) of this section.

    (6) Determine the capture efficiency of the emission capture system 
as the average of the capture efficiencies measured in the three test 
runs.
    (d) Gas-to-gas protocol using a temporary total enclosure or a 
building enclosure. The gas-to-gas protocol compares the mass of TVH 
emissions captured by the emission capture system to the mass of TVH 
emissions not captured. Use a TTE or a building enclosure and the 
procedures in paragraphs (d)(1)

[[Page 533]]

through (5) of this section to measure emission capture system 
efficiency using the gas-to-gas protocol.
    (1) Either use a building enclosure or construct an enclosure around 
the coating operation where coatings and thinners are applied and all 
areas where emissions from these applied coatings and materials 
subsequently occur, such as flash-off, curing, and drying areas. The 
areas of the coating operation where capture devices collect emissions 
generated by the coating operation for routing to an add-on control 
device, such as the entrance and exit areas of an oven or a spray booth, 
must also be inside the enclosure. The enclosure must meet the 
applicable definition of a TTE or building enclosure in Method 204 of

substitute TVH for each occurrence of the term VOC in the methods.
    (i) The sampling points for Method 204B or 204C of appendix M to 40 
CFR part 51 measurement must be upstream from the add-on control device 
and must represent total emissions routed from the capture system and 
entering the add-on control device.
    (ii) If multiple emission streams from the capture system enter the 
add-on control device without a single common duct, then the emissions 
entering the add-on control device must be simultaneously measured in 
each duct, and the total emissions entering the add-on control device 
must be determined.
    (3) Use Method 204D or 204E of appendix M to 40 CFR part 51 to 
measure the total mass, kg, of TVH emissions that are not captured by 
the emission capture system; they are measured as they exit the TTE or 
building enclosure during each capture efficiency test run. To make the 
measurement, substitute TVH for each occurrence of the term VOC in the 
methods.
    (i) Use Method 204D of appendix M to 40 CFR part 51 if the enclosure 
is a TTE.
    (ii) Use Method 204E of appendix M to 40 CFR part 51 if the 
enclosure is a building enclosure. During the capture efficiency 
measurement, all organic compound emitting operations inside the 
building enclosure, other than the coating operation for which capture 
efficiency is being determined, must be shut down but all fans and 
blowers must be operating normally.
    (4) For each capture efficiency test run, determine the percent 
capture efficiency of the emission capture system using Equation 3 of 
this section.

          capture system as measured at the inlet to the add-on control 
          device during the emission capture efficiency test run, kg, 
          determined according to paragraph (d)(2) of this section.
TVHuncaptured = Total mass of TVH that is not captured by the 
          emission capture system and that exits from the TTE or 
          building enclosure during the capture efficiency test run, kg, 
          determined according to paragraph (d)(3) of this section.

Sec. 63.3545  How do I determine the add-on control device emission
destruction or removal efficiency?

    You must use the procedures and test methods in this section to 
determine the add-on control device emission destruction or removal 
efficiency as part of the performance test required by Sec. 63.3540. 
You must conduct three test runs as specified in Sec. 63.7(e)(3) and 
each test run must last at least 1 hour.
    (a) For all types of add-on control devices, use the test methods 
specified in paragraphs (a)(1) through (5) of this section.
    (1) Use Method 1 or 1A of appendix A to 40 CFR part 60, as 
appropriate, to select sampling sites and velocity traverse points.
    (2) Use Method 2, 2A, 2C, 2D, 2F, or 2G of appendix A to 40 CFR part 
60, as appropriate, to measure gas volumetric flow rate.
    (3) Use Method 3, 3A, or 3B of appendix A to 40 CFR part 60, as 
appropriate, for gas analysis to determine dry molecular weight. You may 
also use as an alternative to Method 3B the manual method for measuring 
the oxygen, carbon dioxide, and carbon monoxide content of exhaust gas 
in ANSI/ASME PTC 19.10-1981, ``Flue and Exhaust Gas Analyses [Part 10, 
Instruments and Apparatus]'' (incorporated by reference, see Sec. 
63.14).
    (4) Use Method 4 of appendix A to 40 CFR part 60 to determine stack 
gas moisture.
    (5) Methods for determining gas volumetric flow rate, dry molecular 
weight, and stack gas moisture must be performed, as applicable, during 
each test run.
    (b) Measure total gaseous organic mass emissions as carbon at the 
inlet and outlet of the add-on control device simultaneously using 
either Method 25 or 25A of appendix A to 40 CFR part 60 as specified in 
paragraphs (b)(1) through (5) of this section. You must use the same 
method for both the inlet and outlet measurements.
    (1) Use Method 25 of appendix A to 40 CFR part 60 if the add-on 
control device is an oxidizer and you expect the total gaseous organic 
concentration as carbon to be more than 50 ppm at the control device 
outlet.
    (2) Use Method 25A of appendix A to 40 CFR part 60 if the add-on 
control device is an oxidizer and you expect the total gaseous organic 
concentration as carbon to be 50 ppm or less at the control device 
outlet.
    (3) Use Method 25A of appendix A to 40 CFR part 60 if the add-
control device is not an oxidizer.
    (4) You may use Method 18 of appendix A to 40 CFR part 60 to 
subtract methane emissions from measured total gaseous organic mass 
emissions as carbon.
    (5) Alternatively, any other test method or data that have been 
validated according to the applicable procedures in Method 301 of 40 CFR 
part 63, appendix A, and approved by the Administrator, may be used.
    (c) If two or more add-on control devices are used for the same 
emission stream, then you must measure emissions at the outlet of each 
device. For example, if one add-on control device is a concentrator with 
an outlet for the high-volume dilute stream that has been treated by the 
concentrator, and a second add-on control device is an oxidizer with an 
outlet for the low-volume concentrated stream that is treated with the 
oxidizer, you must measure emissions at the outlet of the oxidizer and 
the high-volume dilute stream outlet of the concentrator.
    (d) For each test run, determine the total gaseous organic emissions 
mass flow rates for the inlet and the outlet of the add-on control 
device using Equation 1 of this section. If there is more than one inlet 
or outlet to the add-on control device, you must calculate the total 
gaseous organic mass flow rate using Equation 1 of this section for each 
inlet and each outlet and then total all of the inlet emissions and 
total all of the outlet emissions.

Where:

Mf = Total gaseous organic emissions mass flow rate, kg per 
          hour (kg/h).

          gas, as determined by Method 25 or Method 25A, ppmvd.
Qsd = Volumetric flow rate of gases entering or exiting the 
          add-on control device, as determined by Method 2, 2A, 2C, 2D, 
          2F, or 2G, dry standard cubic meters/hour (dscm/h).
0.0416 = Conversion factor for molar volume, kg-moles per cubic meter 
          (mol/m\3\) (@ 293 Kelvin (K) and 760 millimeters of mercury

    Note: If Mf is calculated in English units (lb/h), the 
conversion factor for molar volume is 0.00256 lb-moles per cubic foot 
(mol/ft\3\).

    (e) For each test run, determine the add-on control device organic 
emissions destruction or removal efficiency, using Equation 2 of this 
section.
[GRAPHIC] [TIFF OMITTED] TR13NO03.022

Where:

DRE = Organic emissions destruction or removal efficiency of the add-on 
          control device, percent.

          this section, kg/h.
Mfo = Total gaseous organic emissions mass flow rate at the 
          outlet(s) of the add-on control device, using Equation 1 of 
          this section, kg/h.

    (f) Determine the emission destruction or removal efficiency of the 
add-on control device as the average of the efficiencies determined in 
the three test runs and calculated in Equation 2 of this section.



Sec. 63.3546  How do I establish the emission capture system and
add-on control device operating limits during the performance test?

    During the performance test required by Sec. 63.3540 and described 
in Sec. Sec. 63.3543, 63.3544, and 63.3545, you must establish the 
operating limits required by Sec. 63.3492 unless you have received 
approval for alternative monitoring and operating limits under Sec. 
63.8(f) as specified in Sec. 63.3492.
    (a) Thermal oxidizers. If your add-on control device is a thermal 
oxidizer, establish the operating limits according to paragraphs (a)(1) 
and (2) of this section.
    (1) During the performance test, you must monitor and record the 
combustion temperature at least once every 15 minutes during each of the 
three test runs. You must monitor the temperature in the firebox of the 
thermal oxidizer or immediately downstream of the firebox before any 
substantial heat exchange occurs.
    (2) Use the data collected during the performance test to calculate 
and record the average combustion temperature maintained during the 
performance test. That average combustion temperature is the minimum 
operating limit for your thermal oxidizer.
    (b) Catalytic oxidizers. If your add-on control device is a 
catalytic oxidizer, establish the operating limits according to either 
paragraphs (b)(1) and (2) or paragraphs (b)(3) and (4) of this section.
    (1) During the performance test, you must monitor and record the 
temperature at the inlet to the catalyst bed and the temperature 
difference across the catalyst bed at least once every 15 minutes during 
each of the three test runs.
    (2) Use the data collected during the performance test to calculate 
and record the average temperature at the inlet to the catalyst bed and 
the average temperature difference across the catalyst bed maintained 
during the performance test. The average temperature difference is the 
minimum operating limit for your catalytic oxidizer.
    (3) As an alternative to monitoring the temperature difference 
across the catalyst bed, you may monitor the temperature at the inlet to 
the catalyst bed and implement a site-specific inspection and 
maintenance plan for your catalytic oxidizer as specified in

[[Page 536]]

paragraph (b)(4) of this section. During the performance test, you must 
monitor and record the temperature at the inlet to the catalyst bed at 
least once every 15 minutes during each of the three test runs. Use the 
data collected during the performance test to calculate and record the 
average temperature at the inlet to the catalyst bed during the 
performance test. That is the minimum operating limit for your catalytic 
oxidizer.
    (4) You must develop and implement an inspection and maintenance 
plan for your catalytic oxidizer(s) for which you elect to monitor 
according to paragraph (b)(3) of this section. The plan must address, at 
a minimum, the elements specified in paragraphs (b)(4)(i) through (iii) 
of this section.
    (i) Annual sampling and analysis of the catalyst activity (i.e, 
conversion efficiency) following the manufacturer's or catalyst 
supplier's recommended procedures.
    (ii) Monthly inspection of the oxidizer system, including the burner 
assembly and fuel supply lines for problems and, as necessary, adjust 
the equipment to assure proper air-to-fuel mixtures.
    (iii) Annual internal and monthly external visual inspection of the 
catalyst bed to check for channeling, abrasion, and settling. If 
problems are found, you must take corrective action consistent with the 
manufacturer's recommendations and conduct a new performance test to 
determine destruction efficiency according to Sec. 63.3545.
    (c) Regenerative oxidizers. If your add-on control device is a 
regenerative oxidizer, establish operating limits according to 
paragraphs (c)(1) and (2) of this section.
    (1) You must establish all applicable operating limits according to 
paragraphs (a) and (b) of this section.
    (2) You must submit a valve inspection plan that documents the steps 
taken to minimize the amount of leakage during the regenerative process. 
This plan can include, but is not limited to, routine inspection of key 
parameters of the valve operating system (e.g., solenoid valve 
operation, air pressure, hydraulic pressure); visual inspection of the 
valves during internal inspections; and/or actual testing of the 
emission stream for leakage.
    (d) Carbon adsorbers. If your add-on control device is a carbon 
adsorber, establish the operating limits according to paragraphs (d)(1) 
and (2) of this section.
    (1) You must monitor and record the total regeneration desorbing gas 
(e.g., steam or nitrogen) mass flow for each regeneration cycle, and the 
carbon bed temperature after each carbon bed regeneration and cooling 
cycle for the regeneration cycle either immediately preceding or 
immediately following the performance test.
    (2) The operating limits for your carbon adsorber are the minimum 
total desorbing gas mass flow recorded during the regeneration cycle, 
and the maximum carbon bed temperature recorded after the cooling cycle.
    (e) Condensers. If your add-on control device is a condenser, 
establish the operating limits according to paragraphs (e)(1) and (2) of 
this section.
    (1) During the performance test, monitor and record the condenser 
outlet (product side) gas temperature at least once every 15 minutes 
during each of the three test runs.
    (2) Use the data collected during the performance test to calculate 
and record the average condenser outlet (product side) gas temperature 
maintained during the performance test. This average condenser outlet 
gas temperature is the maximum operating limit for your condenser.
    (f) Concentrators. If your add-on control device includes a 
concentrator, you must establish operating limits for the concentrator 
according to paragraphs (f)(1) through (7) of this section.
    (1) During the performance test, monitor and record the inlet 
temperature to the desorption/reactivation zone of the concentrator at 
least once every 15 minutes during each of the three runs of the 
performance test.
    (2) Use the data collected during the performance test to calculate 
and record the average temperature. This is the minimum operating limit 
for the desorption/reactivation zone inlet temperature.
    (3) During the performance test, monitor and record an indicator(s) 
of

[[Page 537]]

performance for the desorption/reactivation fan operation at least once 
every 15 minutes during each of the three runs of the performance test. 
The indicator can be speed in revolutions per minute (rpm), power in 
amps, static pressure, or flow rate.
    (4) Establish a suitable range for the parameter(s) selected based 
on the system design specifications, historical data, and/or data 
obtained concurrent with an emissions performance test. This is the 
operation limit range for the desorption/reactivation fan operation.
    (5) During the performance test, monitor the rotational speed of the 
concentrator at least once every 15 minutes during each of the three 
runs of the performance test.
    (6) Use the data collected during the performance test to calculate 
and record the average rotational speed. This is the minimum operating 
limit for the rotational speed of the concentrator. However, the 
indicator range for the rotational speed may be changed if an 
engineering evaluation is conducted and a determination made that the 
change in speed will not affect compliance with the emission limit.
    (7) Develop and implement an inspection and maintenance plan for the 
concentrator(s) that you elect to monitor according to paragraph (f) of 
this section. The plan must include, at a minimum, annual sampling and 
analysis of the absorbent material (i.e., adsorbent activity) following 
the manufacturer's recommended procedures.
    (g) Emission capture systems. For each capture device that is not 
part of a PTE that meets the criteria of Sec. 63.3544(a), establish an 
operating limit for either the gas volumetric flow rate or duct static 
pressure, as specified in paragraphs (g)(1) and (2) of this section. The 
operating limit for a PTE is specified in Table 4 to this subpart.
    (1) During the capture efficiency determination required by Sec. 
63.3540 and described in Sec. Sec. 63.3543 and 63.3544, you must 
monitor and record either the gas volumetric flow rate at a location 
upstream of the control device, or the duct static pressure at a 
location upstream of the primary fan in each duct of each capture device 
or upstream of the fan that is common to multiple capture devices at 
least once every 15 minutes during each of the three test runs.
    (2) Calculate and record the average gas volumetric flow rate or 
duct static pressure for the three test runs for each capture device or 
system of multiple capture devices. The average gas volumetric flow rate 
is the minimum operating limit for that specific capture device or 
system of multiple capture devices. The average duct static pressure is 
the maximum operating limit for that specific capture device or system 
of multiple capture devices.

Sec. 63.3547  What are the requirements for continuous parameter
monitoring system installation, operation, and maintenance?

    (a) General. You must install, operate, and maintain each CPMS 
specified in paragraphs (c), (e), and (f) of this section according to 
paragraphs (a) (1) through (6) of this section. You must install, 
operate, and maintain each CPMS specified in paragraphs (b) and (d) of 
this section according to paragraphs (a)(3) through (5) of this section.
    (1) The CPMS must complete a minimum of one cycle of operation for 
each successive 15-minute period.
    (2) You must determine the average of all recorded readings for each 
successive 3-hour period of the emission capture system and add-on 
control device operation.
    (3) You must record the results of each inspection, calibration, and 
validation check of the CPMS.
    (4) You must maintain the CPMS at all times and have available 
necessary parts for routine repairs of the monitoring equipment.
    (5) You must operate the CPMS and collect emission capture system 
and add-on control device parameter data at all times that a controlled 
coating operation is operating, except during monitoring malfunctions, 
associated repairs, and required quality assurance or control activities 
(including, if applicable, calibration checks and required zero and span 
adjustments).
    (6) You must not use emission capture system or add-on control 
device

[[Page 538]]

parameter data recorded during monitoring malfunctions, associated 
repairs, out of control periods, or required quality assurance or 
control activities when calculating data averages. You must use all the 
data collected during all other periods in calculating the data averages 
for determining compliance with the emission capture system and add-on 
control device operating limits.
    (7) A monitoring malfunction is any sudden, infrequent, not 
reasonably preventable failure of the CPMS to provide valid data. 
Monitoring failures that are caused in part by poor maintenance or 
careless operation are not malfunctions. Any period for which the 
monitoring system is out of control and data are not available for 
required calculations is a deviation from the monitoring requirements.
    (b) Capture system bypass line. You must meet the requirements of 
paragraph (b)(1) or (2) of this section for each emission capture system 
that contains bypass lines that could divert emissions away from the 
add-on control device to the atmosphere.
    (1) Properly install, maintain, and operate a flow indicator that 
takes a reading at least once every 15 minutes. The flow indicator shall 
be installed at the entrance to any bypass line. Alternatively, install, 
maintain, and operate a bypass line valve indicator or damper indicator 
that indicates valve position.
    (2) Secure the bypass line valve in the nondiverting position with a 
car-seal or a lock-and-key type configuration. A visual inspection of 
the seal or closure mechanism shall be performed at least once every 
month to ensure the valve is maintained in the nondiverting position and 
the vent stream is not diverted through the bypass line.
    (c) Thermal oxidizers and catalytic oxidizers. If you are using a 
thermal oxidizer or catalytic oxidizer as an add-on control device 
(including those used with concentrators or with carbon adsorbers to 
treat desorbed concentrate streams), you must comply with the 
requirements in paragraphs (c)(1) through (3) of this section.
    (1) For a thermal oxidizer, install a gas temperature monitor in the 
firebox of the thermal oxidizer or in the duct immediately downstream of 
the firebox before any substantial heat exchange occurs.
    (2) For a catalytic oxidizer, install a gas temperature monitor 
according to paragraph (c)(2)(i) or (ii) of this section.
    (i) If you establish operating limits according to Sec. 
63.3546(b)(1) and (2), then you must install the gas temperature 
monitors both upstream and downstream of the catalyst bed. The 
temperature monitors must be in the gas stream at the inlet to and the 
outlet of the catalyst bed to measure the temperature difference across 
the bed.
    (ii) If you establish operating limits according to Sec. 
63.3546(b)(3) and (4), then you must install a gas temperature monitor 
upstream of the catalyst bed. The temperature monitor must be in the gas 
stream at the inlet to the catalyst bed to measure the temperature.
    (3) For all thermal oxidizers and catalytic oxidizers, you must meet 
the requirements in paragraphs (a) and (c)(3)(i) through (ii) of this 
section for each gas temperature monitoring device.
    (i) Locate the temperature sensor in a position that provides a 
representative temperature.
    (ii) Use a temperature sensor with a minimum accuracy of 1.2 degrees Celsius or 1 percent 
of the temperature value in degrees Celsius, whichever is larger.
    (d) Carbon adsorbers. If you are using a carbon adsorber as an add-
on control device, you must monitor the total regeneration desorbing gas 
(e.g., steam or nitrogen) mass flow for each regeneration cycle, the 
carbon bed temperature after each regeneration and cooling cycle, and 
comply with paragraphs (a)(3) through (5) and (d)(1) and (2) of this 
section.
    (1) The regeneration desorbing gas mass flow monitor must be an 
integrating device having an accuracy of 10 
percent capable of recording the total regeneration desorbing gas mass 
flow for each regeneration cycle.
    (2) The carbon bed temperature monitor must have a minimum accuracy 
of 1.2 degrees Celsius or 1 
percent of the temperature value in degrees Celsius,

[[Page 539]]

whichever is larger, and must be capable of recording the temperature 
within 15 minutes of completing any carbon bed cooling cycle.
    (e) Condensers. If you are using a condenser, you must monitor the 
condenser outlet (product side) gas temperature and comply with 
paragraphs (a) and (e)(1) and (2) of this section.
    (1) The gas temperature monitor must have a minimum accuracy of 
1 percent of the temperature recorded in degrees 
Celsius or 1.2 degrees Celsius, whichever is 
greater.
    (2) The temperature monitor must provide a continuous gas 
temperature record.

wheel or rotary carbon bed concentrator, you must comply with the 
requirements in paragraphs (f)(1) through (4) of this section.
    (1) You must install a temperature monitor at the inlet to the 
desorption/reactivation zone of the concentrator. The temperature 
monitor must meet the requirements in paragraphs (a) and (c)(3) of this 
section.

desorption/reactivation fan operation, such as speed, power, static 
pressure, or flow rate.
    (3) You must monitor the rotational speed of the concentrator in 
revolutions per hour.
    (4) You must verify the performance of the adsorbent material by 
examining representative samples and testing adsorbent activity per the 
manufacturer's recommendations.

compliance date specified in Sec. 63.3483 and ends on the last day of 
the 12th month following the compliance date. If the compliance date 
occurs on any day other than the first day of a month, then the initial 
compliance period extends through the end of that month plus the next 12 
months. The initial compliance demonstration includes the results of 
emission capture system and add-on control device performance tests 
conducted according to Sec. 63.3553, 63.3554, and 63.3555; the 
operating limits established during the performance tests and the 
results of the continuous parameter monitoring required by Sec. 
63.3557; and documentation of whether you developed and implemented the 
work practice plan required by Sec. 63.3493.
    (4) You do not need to comply with the operating limits for the 
emission capture system and add-on control device required by Sec. 
63.3492 until after you have completed the performance tests specified 
in paragraph (a)(1) of this section. Instead, you must maintain a log 
detailing the operation and maintenance of the emission capture system, 
add-on control device, and continuous parameter monitors during the 
period between the compliance date and the performance test. You must 
begin complying with the operating limits on the date you complete the

required by Sec. 63.3493 no later than the compliance date specified in 
Sec. 63.3483.
    (3) You must complete the initial compliance demonstration for the 
initial compliance period according to the requirements of Sec. 
63.3551. The initial compliance period begins on the applicable 
compliance date specified in Sec. 63.3483 and ends on the last day of 
the 12th month following the compliance date. If the compliance date 
occurs on any day other than the first day of a month, then the initial 
compliance period extends through the end of that month plus the next 12 
months. The initial compliance demonstration includes the results of 
emission capture system and add-on control device performance tests 
conducted according to Sec. Sec. 63.3553, 63.3554, and 63.3555; the 
operating limits established during the performance tests and the 
results of the continuous parameter monitoring required by Sec. 
63.3557; and documentation of whether you developed and implemented the 
work practice plan required by Sec. 63.3493.



Sec. 63.3551  How do I demonstrate initial compliance?

    (a) You may use the control efficiency/outlet concentration option 
for any coating operation, for any group of coating operations within a 
subcategory or coating type segment, or for all of the coating 
operations within a subcategory or coating type segment. You must use 
the compliant material option, the emission rate without add-on controls 
option, or the emission rate with add-on controls option for any coating 
operation in the affected source for which you do not use the control 
efficiency/outlet concentration option. To demonstrate initial 
compliance, the coating operation(s) for which you use the control 
efficiency/outlet concentration option must meet the applicable levels 
of emission reduction in Sec. 63.3490. You must conduct a separate 
initial compliance demonstration for each one and two-piece draw and 
iron can body coating, sheetcoating, three-piece can body assembly 
coating, and end coating affected source. You must meet all the 
requirements of this section to demonstrate initial compliance with the 
emission limitations. When calculating the organic HAP emission rate 
according to this section, do not include any coatings or thinners used 
on coating operations for which you use the compliant material option, 
the emission rate without add-on controls option, or the emission rate 
with add-on controls option. You do not need to redetermine the mass of 
organic HAP in coatings or thinners that have been reclaimed onsite and 
reused in the coating operation(s) for which you use the emission rate 
with add-on controls option.
    (b) Compliance with operating limits. You must establish and 
demonstrate continuous compliance during the initial compliance period 
with the operating limits required by Sec. 63.3492, using the 
procedures specified in Sec. Sec. 63.3556 and 63.3557.
    (c) Compliance with work practice requirements. You must develop, 
implement, and document your implementation of the work practice plan 
required by Sec. 63.3493 during the initial compliance period as 
specified in Sec. 63.3512.
    (d) Compliance demonstration. To demonstrate initial compliance, the 
coating operation(s) for which you use the control efficiency/outlet 
concentration option must meet the applicable levels of emission 
reduction in Sec. 63.3490. You must keep all records applicable to the 
control efficiency/outlet concentration option as required by Sec. Sec. 
63.3512 and 63.3513. As part of the Notification of Compliance Status 
required by Sec. 63.3510, you must identify the coating operation(s) 
for which you used the control efficiency/outlet concentration option 
and submit a statement that the coating operation(s) was in compliance 
with the emission limitations during the initial compliance period 
because you achieved the operating limits required by Sec. 63.3492 and 
the work practice standards required by Sec. 63.3493.

[[Page 541]]



Sec. 63.3552  How do I demonstrate continuous compliance with the
emission limitations?

    (a) To demonstrate continuous compliance with the emission 
limitations using the control efficiency/outlet concentration option, 
the organic HAP emission rate for each compliance period must be equal 
to or less than 20 ppmvd or must be reduced by the amounts specified in 
Sec. 63.3490. A compliance period consists of 12 months. Each month 
after the end of the initial compliance period described in Sec. 
63.3550 is the end of a compliance period consisting of that month and 
the preceding 11 months.
    (b) You must demonstrate continuous compliance with each operating 
limit required by Sec. 63.3492 that applies to you, as specified in 
Table 4 to this subpart. If an operating parameter is out of the allowed 
range specified in Table 4 to this subpart, this is a deviation from the 
operating limit that must be reported as specified in Sec. Sec. 
63.3510(b)(6) and 63.3511(a)(7).
    (c) You must meet the requirements for bypass lines in Sec. 
63.3557(b). If any bypass line is opened and emissions are diverted to 
the atmosphere when the coating operation is running, this is a 
deviation that must be reported as specified in Sec. Sec. 63.3510(b)(6) 
and 63.3511(a)(7). For purposes of demonstrating compliance, you must 
treat the materials used during a deviation on a controlled coating 
operation as if they were used on an uncontrolled coating operation for 
the time period of the deviation.
    (d) You must demonstrate continuous compliance with the work 
practice standards in Sec. 63.3493. If you did not develop a work 
practice plan or you did not implement the plan or you did not keep the 
records required by Sec. 63.3512(j)(8), this is a deviation from the 
work practice standards that must be reported as specified in Sec. Sec. 
63.3510(b)(6) and 63.3511(a)(7).
    (e) As part of each semiannual compliance report required in Sec. 
63.3511, you must identify the coating operation(s) for which you used 
the control efficiency/outlet concentration option. If there were no 
deviations from the operating limits or work practice standards, submit 
a statement that you were in compliance with the emission limitations 
during the reporting period because the organic HAP emission rate for 
each compliance period was less than 20 ppmvd or was reduced by the 
amount specified in Sec. 63.3490, and you achieved the operating limits 
required by Sec. 63.3492 and the work practice standards required by 
Sec. 63.3493 during each compliance period.
    (f) [Reserved]
    (g) Consistent with Sec. Sec. 63.6(e) and 63.7(e)(1), deviations 
that occur during a period of startup, shutdown, or malfunction of the 
emission capture system, add-on control device, or coating operation 
that may affect emission capture or control device efficiency are not 
violations if you demonstrate to the Administrator's satisfaction that 
you were operating in accordance with Sec. 63.6(e)(1). The 
Administrator will determine whether deviations that occur during a 
period you identify as a startup, shutdown, or malfunction are 
violations, according to the provisions in Sec. 63.6(e).
    (h) You must maintain records applicable to the control efficiency/
outlet concentration option as specified in Sec. Sec. 63.3512 and 
63.3513.

[68 FR 64446, Nov. 13, 2003, as amended at 71 FR 20464, Apr. 20, 2006]



Sec. 63.3553  What are the general requirements for performance tests?

    (a) You must conduct each performance test required by Sec. 63.3550 
according to the requirements of Sec. 63.7(e)(1) and under the 
conditions in this section unless you obtain a waiver of the performance 
test according to the provisions in Sec. 63.7(h).
    (1) Representative coating operating conditions. You must conduct 
the performance test under representative operating conditions for the 
coating operation(s). Operations during periods of startup, shutdown, or 
malfunction and during periods of nonoperation do not constitute 
representative conditions. You must record the process information that 
is necessary to document operating conditions during the test and 
explain why the conditions represent normal operation.
    (2) Representative emission capture system and add-on control device 
operating

[[Page 542]]

conditions. You must conduct the performance test when the emission 
capture system and add-on control device are operating at a 
representative flow rate, and the add-on control device is operating at 
a representative inlet concentration. You must record information that 
is necessary to document emission capture system and add-on control 
device operating conditions during the test and explain why the 
conditions represent normal operation.
    (b) You must conduct each performance test of an emission capture 
system according to the requirements in Sec. 63.3554. You must conduct 
each performance test of an add-on control device according to the 
requirements in Sec. 63.3555.



Sec. 63.3554  How do I determine the emission capture system 
efficiency?

    The capture efficiency of your emission capture system must be 100 
percent to use the control efficiency/outlet concentration option. You 
may assume the capture system efficiency is 100 percent if both of the 
conditions in paragraphs (a) and (b) of this section are met.
    (a) The capture system meets the criteria in Method 204 of appendix 
M to 40 CFR part 51 for a PTE and directs all the exhaust gases from the 
enclosure to an add-on control device.
    (b) All coatings and thinners used in the coating operation are 
applied within the capture system, and coating solvent flash-off, 
curing, and drying occurs within the capture system. This criterion is 
not met if parts enter the open shop environment when being moved 
between a spray booth and a curing oven.



Sec. 63.3555  How do I determine the outlet THC emissions and 
add-on control device emission destruction or removal efficiency?

    You must use the procedures and test methods in this section to 
determine either the outlet THC emissions or add-on control device 
emission destruction or removal efficiency as part of the performance 
test required by Sec. 63.3550. You must conduct three test runs as 
specified in Sec. 63.7(e)(3), and each test run must last at least 1 
hour.
    (a) For all types of add-on control devices, use the test methods 
specified in paragraphs (a)(1) through (5) of this section.
    (1) Use Method 1 or 1A of appendix A to 40 CFR part 60, as 
appropriate, to select sampling sites and velocity traverse points.
    (2) Use Method 2, 2A, 2C, 2D, 2F, or 2G of appendix A to 40 CFR part 
60, as appropriate, to measure gas volumetric flow rate.
    (3) Use Method 3, 3A, or 3B of appendix A to 40 CFR part 60, as 
appropriate, for gas analysis to determine dry molecular weight. You may 
also use as an alternative to Method 3B, the manual method for measuring 
the oxygen, carbon dioxide, and carbon monoxide content of exhaust gas 
in ANSI/ASME PTC 19.10-1981, ``Flue and Exhaust Gas Analyses [Part 10, 
Instruments and Apparatus]'' (incorporated by reference, see Sec. 
63.14).
    (4) Use Method 4 of appendix A to 40 CFR part 60 to determine stack 
gas moisture.
    (5) Methods for determining gas volumetric flow rate, dry molecular 
weight, and stack gas moisture must be performed, as applicable, during 
each test run.
    (b) Measure total gaseous organic mass emissions as carbon at the 
inlet and outlet of the add-on control device simultaneously using 
either Method 25 or 25A of appendix A to 40 CFR part 60 as specified in 
paragraphs (b)(1) through (3) of this section. You must use the same 
method for both the inlet and outlet measurements.
    (1) Use Method 25 of appendix A to 40 CFR part 60 if the add-on 
control device is an oxidizer, and you expect the total gaseous organic 
concentration as carbon to be more than 50 ppm at the control device 
outlet.
    (2) Use Method 25A of appendix A to 40 CFR part 60 if the add-on 
control device is an oxidizer, and you expect the total gaseous organic 
concentration as carbon to be 50 ppm or less at the control device 
outlet.
    (3) Use Method 25A of appendix A to 40 CFR part 60 if the add-on 
control device is not an oxidizer.
    (4) You may use Method 18 of appendix A to 40 CFR part 60 to 
subtract methane emissions from measured

[[Page 543]]

total gaseous organic mass emissions as carbon.
    (5) Alternatively, any other test method or data that have been 
validated according to the applicable procedures in Method 301 of 40 CFR 
part 63, appendix A, and approved by the Administrator may be used.
    (c) If two or more add-on control devices are used for the same 
emission stream, then you must measure emissions at the outlet of each 
device. For example, if one add-on control device is a concentrator with 
an outlet for the high-volume dilute stream that has been treated by the 
concentrator and a second add-on control device is an oxidizer with an 
outlet for the low-volume, concentrated stream that is treated with the 
oxidizer, you must measure emissions at the outlet of the oxidizer and 
the high-volume dilute stream outlet of the concentrator.
    (d) For each test run, determine the total gaseous organic emissions 
mass flow rates for the inlet and outlet of the add-on control device 
using Equation 1 of this section. If there is more than one inlet or 
outlet to the add-on control device, you must calculate the total 
gaseous organic mass flow rate using Equation 1 of this section for each 
inlet and each outlet and then total all of the inlet emissions and 
total all of the outlet emissions.

    (e) For each test run, determine the add-on control device organic 
emissions destruction or removal efficiency using Equation 2 of this 
section.

add-on control device as the average of the efficiencies determined in 
the three test runs and calculated in Equation 2 of this section.



Sec. 63.3556  How do I establish the emission capture system and
add-on control device operating limits during the performance test?

    During the performance test required by Sec. 63.3550 and described 
in Sec. Sec. 63.3553, 63.3554, and 63.3555, you must establish the 
operating limits required by Sec. 63.3492 according to this section, 
unless you have received approval for alternative monitoring and 
operating limits under Sec. 63.8(f) as specified in Sec. 63.3492.
    (a) Thermal oxidizers. If your add-on control device is a thermal 
oxidizer, establish the operating limits according to paragraphs (a)(1) 
and (2) of this section.
    (1) During the performance test, you must monitor and record the 
combustion temperature at least once every 15 minutes during each of the 
three test

[[Page 544]]

runs. You must monitor the temperature in the firebox of the thermal 
oxidizer or immediately downstream of the firebox before any substantial 
heat exchange occurs.
    (2) Use the data collected during the performance test to calculate 
and record the average combustion temperature maintained during the 
performance test. That average combustion temperature is the minimum 
operating limit for your thermal oxidizer.
    (b) Catalytic oxidizers. If your add-on control device is a 
catalytic oxidizer, establish the operating limits according to either 
paragraphs (b)(1) and (2) or paragraphs (b)(3) and (4) of this section.
    (1) During the performance test, you must monitor and record the 
temperature at the inlet to the catalyst bed and the temperature 
difference across the catalyst bed at least once every 15 minutes during 
each of the three test runs.
    (2) Use the data collected during the performance test to calculate 
and record the average temperature at the inlet to the catalyst bed and 
the average temperature difference across the catalyst bed maintained 
during the performance test. The average temperature difference is the 
minimum operating limit for your catalytic oxidizer.
    (3) As an alternative to monitoring the temperature difference 
across the catalyst bed, you may monitor the temperature at the inlet to 
the catalyst bed and implement a site-specific inspection and 
maintenance plan for your catalytic oxidizer as specified in paragraph 
(b)(4) of this section. During the performance test, you must monitor 
and record the temperature at the inlet to the catalyst bed at least 
once every 15 minutes during each of the three test runs. Use the data 
collected during the performance test to calculate and record the 
average temperature at the inlet to the catalyst bed during the 
performance test. That is the minimum operating limit for your catalytic 
oxidizer.
    (4) You must develop and implement an inspection and maintenance 
plan for your catalytic oxidizer(s) for which you elect to monitor 
according to paragraph (b)(3) of this section. The plan must address, at 
a minimum, the elements specified in paragraphs (b)(4)(i) through (iii) 
of this section.
    (i) Annual sampling and analysis of the catalyst activity (i.e., 
conversion efficiency) following the manufacturer's or catalyst 
supplier's recommended procedures.
    (ii) Monthly inspection of the oxidizer system, including the burner 
assembly and fuel supply lines for problems and, as necessary, adjust 
the equipment to assure proper air-to-fuel mixtures.
    (iii) Annual internal and monthly external visual inspection of the 
catalyst bed to check for channeling, abrasion, and settling. If 
problems are found, you must take corrective action consistent with the 
manufacturer's recommendations and conduct a new performance test to 
determine destruction efficiency according to Sec. 63.3555.
    (c) Regenerative oxidizers. If your add-on control device is a 
regenerative oxidizer, establish operating limits according to 
paragraphs (c)(1) and (2) of this section.
    (1) You must establish all applicable operating limits according to 
paragraphs (a) and (b) of this section.
    (2) You must submit a valve inspection plan that documents the steps 
taken to minimize the amount of leakage during the regenerative process. 
This plan can include, but is not limited to, routine inspection of key 
parameters of the valve operating system (e.g., solenoid valve 
operation, air pressure, hydraulic pressure), visual inspection of the 
valves during internal inspections, and/or actual testing of the 
emission stream for leakage.
    (d) Carbon adsorbers. If your add-on control device is a carbon 
adsorber, establish the operating limits according to paragraphs (d)(1) 
and (2) of this section.
    (1) You must monitor and record the total regeneration desorbing gas 
(e.g., steam or nitrogen) mass flow for each regeneration cycle, and the 
carbon bed temperature after each carbon bed regeneration and cooling 
cycle for the regeneration cycle either immediately preceding or 
immediately following the performance test.
    (2) The operating limits for your carbon adsorber are the minimum 
total

[[Page 545]]

desorbing gas mass flow recorded during the regeneration cycle and the 
maximum carbon bed temperature recorded after the cooling cycle.
    (e) Condensers. If your add-on control device is a condenser, 
establish the operating limits according to paragraphs (e)(1) and (2) of 
this section.
    (1) During the performance test, monitor and record the condenser 
outlet (product side) gas temperature at least once every 15 minutes 
during each of the three test runs.
    (2) Use the data collected during the performance test to calculate 
and record the average condenser outlet (product side) gas temperature 
maintained during the performance test. This average condenser outlet 
gas temperature is the maximum operating limit for your condenser.
    (f) Concentrators. If your add-on control device includes a 
concentrator, you must establish operating limits for the concentrator 
according to paragraphs (f)(1) through (7) of this section.
    (1) During the performance test, monitor and record the inlet 
temperature to the desorption/reactivation zone of the concentrator at 
least once every 15 minutes during each of the three runs of the 
performance test.
    (2) Use the data collected during the performance test to calculate 
and record the average temperature. This is the minimum operating limit 
for the desorption/reactivation zone inlet temperature.
    (3) During the performance test, monitor and record an indicator(s) 
of performance for the desorption/reactivation fan operation at least 
once every 15 minutes during each of the three runs of the performance 
test. The indicator can be speed in rpm, power in amps, static pressure, 
or flow rate.
    (4) Establish a suitable range for the parameter(s) selected based 
on the system design specifications, historical data, and/or data 
obtained concurrent with an emissions performance test. This is the 
operation limit range for the desorption/reactivation fan operation.
    (5) During the performance test, monitor the rotational speed of the 
concentrator at least once every 15 minutes during each of the three 
runs of the performance test.
    (6) Use the data collected during the performance test to calculate 
and record the average rotational speed. This is the minimum operating 
limit for the rotational speed of the concentrator. However, the 
indicator range for the rotational speed may be changed if an 
engineering evaluation is conducted and a determination made that the 
change in speed will not affect compliance with the emission limit.
    (7) Develop and implement an inspection and maintenance plan for the 
concentrator(s) that you elect to monitor according to paragraph (f) of 
this section. The plan must include, at a minimum, annual sampling and 
analysis of the absorbent material (i.e., adsorbent activity) following 
the manufacturer's recommended procedures.
    (g) Emission capture systems. For each capture device that is part 
of a PTE that meets the criteria of Sec. 63.3554, the operating limit 
for a PTE is specified in Table 4 to this subpart.



Sec. 63.3557  What are the requirements for continuous parameter
monitoring system installation, operation, and maintenance?

    (a) General. You must install, operate, and maintain each CPMS 
specified in paragraphs (c), (e), and (f) of this section according to 
paragraphs (a)(1) through (6) of this section. You must install, 
operate, and maintain each CPMS specified in paragraphs (b) and (d) of 
this section according to paragraphs (a)(3) through (5) of this section.
    (1) The CPMS must complete a minimum of one cycle of operation for 
each successive 15-minute period.
    (2) You must determine the average of all recorded readings for each 
successive 3-hour period of the emission capture system and add-on 
control device operation.
    (3) You must record the results of each inspection, calibration, and 
validation check of the CPMS.
    (4) You must maintain the CPMS at all times and have available 
necessary parts for routine repairs of the monitoring equipment.
    (5) You must operate the CPMS and collect emission capture system 
and add-on control device parameter data at all times that a controlled 
coating operation is operating, except during

[[Page 546]]

monitoring malfunctions, associated repairs, and required quality 
assurance or control activities (including, if applicable, calibration 
checks and required zero and span adjustments).
    (6) You must not use emission capture system or add-on control 
device parameter data recorded during monitoring malfunctions, 
associated repairs, out of control periods, or required quality 
assurance or control activities when calculating data averages. You must 
use all the data collected during all other periods in calculating the 
data averages for determining compliance with the emission capture 
system and add-on control device operating limits.
    (7) A monitoring malfunction is any sudden, infrequent, not 
reasonably preventable failure of the CPMS to provide valid data. 
Monitoring failures that are caused in part by poor maintenance or 
careless operation are not malfunctions. Any period for which the 
monitoring system is out of control and data are not available for 
required calculations is a deviation from the monitoring requirements.

takes a reading at least once every 15 minutes. The flow indicator shall 
be installed at the entrance to any bypass line.
    (2) Secure the bypass line valve in the nondiverting position with a 
car-seal or lock-and-key type configuration. A visual inspection of the 
seal or closure mechanism shall be performed at least once every month 
to ensure the valve is maintained in the nondiverting position, and the 
vent stream is not diverted through the bypass line.

 Subpart MMMM_National Emission Standards for Hazardous Air Pollutants 
      for Surface Coating of Miscellaneous Metal Parts and Products

    Source: 69 FR 157, Jan. 2, 2004, unless otherwise noted.

                        What This Subpart Covers



Sec. 63.3880  What is the purpose of this subpart?

    This subpart establishes national emission standards for hazardous 
air pollutants (NESHAP) for miscellaneous metal parts and products 
surface coating facilities. This subpart also establishes requirements 
to demonstrate initial and continuous compliance with the emission 
limitations.



Sec. 63.3881  Am I subject to this subpart?

    (a) Miscellaneous metal parts and products include, but are not 
limited to, metal components of the following types of products as well 
as the products themselves: motor vehicle parts and accessories, 
bicycles and sporting goods, recreational vehicles, extruded aluminum 
structural components, railroad cars, heavy duty trucks, medical 
equipment, lawn and garden equipment, electronic equipment, magnet wire, 
steel drums, industrial machinery, metal pipes, and numerous other 
industrial, household, and consumer products. Except as provided in 
paragraph (c) of this section, the source category to which this subpart 
applies is the surface coating of any miscellaneous metal parts or 
products, as described in paragraph (a)(1) of this section, and it 
includes the subcategories listed in paragraphs (a)(2) through (6) of 
this section.
    (1) Surface coating is the application of coating to a substrate 
using, for example, spray guns or dip tanks. When application of coating 
to a substrate occurs, then surface coating also includes associated 
activities, such as surface preparation, cleaning, mixing, and storage. 
However, these activities do not comprise surface coating if they are 
not directly related to the application of the coating. Coating 
application with handheld, non-refillable aerosol containers, touch-up 
markers, marking pens, or the application of paper film or plastic film 
which may be pre-coated with an adhesive by the manufacturer are not 
coating operations for the purposes of this subpart.
    (2) The general use coating subcategory includes all surface coating 
operations that are not high performance, magnet wire, rubber-to-metal, 
or extreme performance fluoropolymer coating operations.
    (3) The high performance coating subcategory includes surface 
coating operations that are performed using coatings that meet the 
definition of high performance architectural coating or high temperature 
coating in Sec. 63.3981.
    (4) The magnet wire coating subcategory includes surface coating 
operations that are performed using coatings that meet the definition of 
magnet wire coatings in Sec. 63.3981.
    (5) The rubber-to-metal coatings subcategory includes surface 
coating operations that are performed using coatings that meet the 
definition of rubber-to-metal coatings in Sec. 63.3981.
    (6) The extreme performance fluoropolymer coatings subcategory 
includes surface coating operations that are performed using coatings 
that meet the definition of extreme performance fluoropolymer coatings 
in Sec. 63.3981.
    (b) You are subject to this subpart if you own or operate a new, 
reconstructed, or existing affected source, as defined in Sec. 63.3882, 
that uses 946 liters (250 gallons (gal)) per year, or more, of coatings 
that contain hazardous air pollutants (HAP) in the surface coating of 
miscellaneous metal parts and products defined in paragraph (a) of this 
section; and that is a major source, is located at a major source, or is 
part of a major source of emissions of HAP. A major source of HAP 
emissions is any stationary source or group of stationary sources 
located within a contiguous area and under common control that emits or 
has the potential to emit any single HAP at a rate of 9.07

[[Page 559]]

megagrams (Mg) (10 tons) or more per year or any combination of HAP at a 
rate of 22.68 Mg (25 tons) or more per year. You do not need to include 
coatings that meet the definition of non-HAP coating contained in Sec. 
63.3981 in determining whether you use 946 liters (250 gal) per year, or 
more, of coatings in the surface coating of miscellaneous metal parts 
and products.
    (c) This subpart does not apply to surface coating or a coating 
operation that meets any of the criteria of paragraphs (c)(1) through 
(17) of this section.
    (1) A coating operation conducted at a facility where the facility 
uses only coatings, thinners and other additives, and cleaning materials 
that contain no organic HAP, as determined according to Sec. 
63.3941(a).
    (2) Surface coating operations that occur at research or laboratory 
facilities, or is part of janitorial, building, and facility maintenance 
operations, or that occur at hobby shops that are operated for 
noncommercial purposes.
    (3) Coatings used in volumes of less than 189 liters (50 gal) per 
year, provided that the total volume of coatings exempt under this 
paragraph does not exceed 946 liters (250 gal) per year at the facility.
    (4) The surface coating of metal parts and products performed on-
site at installations owned or operated by the Armed Forces of the 
United States (including the Coast Guard and the National Guard of any 
such State) or the National Aeronautics and Space Administration, or the 
surface coating of military munitions manufactured by or for the Armed 
Forces of the United States (including the Coast Guard and the National 
Guard of any such State).
    (5) Surface coating where plastic is extruded onto metal wire or 
cable or metal parts or products to form a coating.
    (6) Surface coating of metal components of wood furniture that meet 
the applicability criteria for wood furniture manufacturing (subpart JJ 
of this part).
    (7) Surface coating of metal components of large appliances that 
meet the applicability criteria for large appliance surface coating 
(subpart NNNN of this part).
    (8) Surface coating of metal components of metal furniture that meet 
the applicability criteria for metal furniture surface coating (subpart 
RRRR of this part).
    (9) Surface coating of metal components of wood building products 
that meet the applicability criteria for wood building products surface 
coating (subpart QQQQ of this part).
    (10) Surface coating of metal components of aerospace vehicles that 
meet the applicability criteria for aerospace manufacturing and rework 
(40 CFR part 63, subpart GG).
    (11) Surface coating of metal parts intended for use in an aerospace 
vehicle or component using specialty coatings as defined in appendix A 
to subpart GG of this part.
    (12) Surface coating of metal components of ships that meet the 
applicability criteria for shipbuilding and ship repair (subpart II of 
this part).
    (13) Surface coating of metal using a web coating process that meets 
the applicability criteria for paper and other web coating (subpart JJJJ 
of this part).
    (14) Surface coating of metal using a coil coating process that 
meets the applicability criteria for metal coil coating (subpart SSSS of 
this part).
    (15) Surface coating of boats or metal parts of boats (including, 
but not limited to, the use of assembly adhesives) where the facility 
meets the applicability criteria for boat manufacturing facilities 
(subpart VVVV of this part), except where the surface coating of the 
boat is a metal coating operation performed on personal watercraft or 
parts of personal watercraft. This subpart does apply to metal coating 
operations performed on personal watercraft and parts of personal 
watercraft.
    (16) Surface coating of assembled on-road vehicles that meet the 
applicability criteria for the assembled on-road vehicle subcategory in 
plastic parts and products surface coating (40 CFR part 63, subpart 
PPPP).
    (17) Surface coating of metal components of automobiles and light-
duty trucks that meets the applicability criteria in Sec. 63.3082(b) 
for the Surface Coating of Automobiles and Light-Duty Trucks NESHAP (40 
CFR part 63,

[[Page 560]]

subpart IIII) at a facility that meets the applicability criteria in 
Sec. 63.3081(b).
    (d) If your facility meets the applicability criteria in Sec. 
63.3081(b) of the Surface Coating of Automobiles and Light-Duty Trucks 
NESHAP (40 CFR part 63, subpart IIII), and you perform surface coating 
of metal parts or products that meets both the applicability criteria in 
Sec. 63.3082(c) and the applicability criteria of the Surface Coating 
of Miscellaneous Metal Parts and Products (40 CFR part 63, subpart 
MMMM), then for the surface coating of any or all of your metal parts or 
products that meets the applicability criteria in Sec. 63.3082(c), you 
may choose to comply with the requirements of subpart IIII of this part 
in lieu of complying with the Surface Coating of Miscellaneous Metal 
Parts and Products NESHAP. Surface coating operations on metal parts or 
products (e.g., parts for motorcycles or lawnmowers) not intended for 
use in automobiles, light-duty trucks, or other motor vehicles as 
defined in Sec. 63.3176 cannot be made part of your affected source 
under subpart IIII of this part.
    (e) If you own or operate an affected source that meets the 
applicability criteria of this subpart and at the same facility you also 
perform surface coating that meets the applicability criteria of any 
other final surface coating NESHAP in this part you may choose to comply 
as specified in paragraph (e)(1), (2), or (3) of this section.
    (1) You may have each surface coating operation that meets the 
applicability criteria of a separate NESHAP comply with that NESHAP 
separately.
    (2) You may comply with the emission limitation representing the 
predominant surface coating activity at your facility, as determined 
according to paragraphs (e)(2)(i) and (ii) of this section. However, you 
may not establish high performance, rubber-to-metal, or extreme 
performance fluoropolymer coating operations as the predominant 
activity. You must not consider any surface coating activity that is 
subject to the Surface Coating of Automobiles and Light-Duty Trucks 
NESHAP (40 CFR part 63, subpart IIII) in determining the predominant 
surface coating activity at your facility.
    (i) If a surface coating operation accounts for 90 percent or more 
of the surface coating activity at your facility (that is, the 
predominant activity), then compliance with the emission limitations of 
the predominant activity for all surface coating operations constitutes 
compliance with these and other applicable surface coating NESHAP. In 
determining predominant activity, you must include coating activities 
that meet the applicability criteria of other surface coating NESHAP and 
constitute more than 1 percent of total coating activities at your 
facility. Coating activities that meet the applicability criteria of 
other surface coating NESHAP but comprise less than 1 percent of coating 
activities need not be included in the determination of predominant 
activity but must be included in the compliance calculation.
    (ii) You must use liters (gal) of solids used as a measure of 
relative surface coating activity over a representative period of 
operation. You may estimate the relative volume of coating solids used 
from parameters other than coating consumption and volume solids content 
(e.g., design specifications for the parts or products coated and the 
number of items produced). The determination of predominant activity 
must accurately reflect current and projected coating operations and 
must be verifiable through appropriate documentation. The use of 
parameters other than coating consumption and volume solids content must 
be approved by the Administrator. You may use data for any reasonable 
time period of at least 1 year in determining the relative amount of 
coating activity, as long as they represent the way the source will 
continue to operate in the future and are approved by the Administrator. 
You must determine the predominant activity at your facility and submit 
the results of that determination with the initial notification required 
by Sec. 63.3910(b). You must also determine predominant activity 
annually and include the determination in the next semi-annual 
compliance report required by Sec. 63.3920(a).
    (3) You may comply with a facility-specific emission limit 
calculated from the relative amount of coating activity

[[Page 561]]

that is subject to each emission limit. If you elect to comply using the 
facility-specific emission limit alternative, then compliance with the 
facility-specific emission limit and the emission limitations in this 
subpart for all surface coating operations constitutes compliance with 
this and other applicable surface coating NESHAP. The procedures for 
calculating the facility-specific emission limit are specified in Sec. 
63.3890. In calculating a facility-specific emission limit, you must 
include coating activities that meet the applicability criteria of other 
surface coating NESHAP and constitute more than 1 percent of total 
coating activities at your facility. You must not consider any surface 
coating activity that is subject to the Surface Coating of Automobiles 
and Light-Duty Trucks NESHAP (40 CFR part 63, subpart IIII) in 
determining a facility-specific emission limit for your facility. 
Coating activities that meet the applicability criteria of other surface 
coating NESHAP but comprise less than 1 percent of total coating 
activities need not be included in the calculation of the facility-
specific emission limit but must be included in the compliance 
calculations.

Sec. 63.3882  What parts of my plant does this subpart cover?

    (a) This subpart applies to each new, reconstructed, and existing 
affected source within each of the four subcategories listed in Sec. 
63.3881(a).
    (b) The affected source is the collection of all of the items listed 
in paragraphs (b)(1) through (4) of this section that are used for 
surface coating of miscellaneous metal parts and products within each 
subcategory.
    (1) All coating operations as defined in Sec. 63.3981;
    (2) All storage containers and mixing vessels in which coatings, 
thinners and/or other additives, and cleaning materials are stored or 
mixed;
    (3) All manual and automated equipment and containers used for 
conveying coatings, thinners and/or other additives, and cleaning 
materials; and
    (4) All storage containers and all manual and automated equipment 
and containers used for conveying waste materials generated by a coating 
operation.
    (c) An affected source is a new affected source if you commenced its 
construction after August 13, 2002 and the construction is of a 
completely new miscellaneous metal parts and products surface coating 
facility where previously no miscellaneous metal parts and products 
surface coating facility had existed.
    (d) An affected source is reconstructed if it meets the criteria as 
defined in Sec. 63.2.
    (e) An affected source is existing if it is not new or 
reconstructed.



Sec. 63.3883  When do I have to comply with this subpart?

    The date by which you must comply with this subpart is called the 
compliance date. The compliance date for each type of affected source is 
specified in paragraphs (a) through (c) of this section. The compliance 
date begins the initial compliance period during which you conduct the 
initial compliance demonstration described in Sec. Sec. 63.3940, 
63.3950, and 63.3960.
    (a) For a new or reconstructed affected source, the compliance date 
is the applicable date in paragraph (a)(1) or (2) of this section:
    (1) If the initial startup of your new or reconstructed affected 
source is before January 2, 2004, the compliance date is January 2, 
2004.
    (2) If the initial startup of your new or reconstructed affected 
source occurs after January 2, 2004, the compliance date is the date of 
initial startup of your affected source.
    (b) For an existing affected source, the compliance date is the date 
3 years after January 2, 2004.
    (c) For an area source that increases its emissions or its potential 
to emit such that it becomes a major source of HAP emissions, the 
compliance date is specified in paragraphs (c)(1) and (2) of this 
section.
    (1) For any portion of the source that becomes a new or 
reconstructed affected source subject to this subpart, the compliance 
date is the date of initial startup of the affected source or January 2, 
2004, whichever is later.

[[Page 562]]

    (2) For any portion of the source that becomes an existing affected 
source subject to this subpart, the compliance date is the date 1 year 
after the area source becomes a major source or 3 years after January 2, 
2004, whichever is later.
    (d) You must meet the notification requirements in Sec. 63.3910 
according to the dates specified in that section and in subpart A of 
this part. Some of the notifications must be submitted before the 
compliance dates described in paragraphs (a) through (c) of this 
section.

                          Emission Limitations



Sec. 63.3890  What emission limits must I meet?

    (a) For a new or reconstructed affected source, you must limit 
organic HAP emissions to the atmosphere from the affected source to the 
applicable limit specified in paragraphs (a)(1) through (5) of this 
section, except as specified in paragraph (c) of this section, 
determined according to the requirements in Sec. 63.3941, Sec. 
63.3951, or Sec. 63.3961.
    (1) For each new general use coating affected source, limit organic 
HAP emissions to no more than 0.23 kilograms (kg) (1.9 pound (lb)) 
organic HAP per liter (gal) coating solids used during each 12-month 
compliance period.
    (2) For each new high performance coating affected source, limit 
organic HAP emissions to no more than 3.3 kg (27.5 lb) organic HAP per 
liter (gal) coating solids used during each 12-month compliance period.
    (3) For each new magnet wire coating affected source, limit organic 
HAP emissions to no more than 0.050 kg (0.44 lb) organic HAP per liter 
(gal) coating solids used during each 12-month compliance period.
    (4) For each new rubber-to-metal coating affected source, limit 
organic HAP emissions to no more than 0.81 kg (6.8 lb) organic HAP per 
liter (gal) coating solids used during each 12-month compliance period.
    (5) For each new extreme performance fluoropolymer coating affected 
source, limit organic HAP emissions to no more than 1.5 kg (12.4 lb) 
organic HAP per liter (gal) coating solids used during each 12-month 
compliance period.
    (b) For an existing affected source, you must limit organic HAP 
emissions to the atmosphere from the affected source to the applicable 
limit specified in paragraphs (b)(1) through (5) of this section, except 
as specified in paragraph (c) of this section, determined according to 
the requirements in Sec. 63.3941, Sec. 63.3951, or Sec. 63.3961.
    (1) For each existing general use coating affected source, limit 
organic HAP emissions to no more than 0.31 kg (2.6 lb) organic HAP per 
liter (gal) coating solids used during each 12-month compliance period.
    (2) For each existing high performance coating affected source, 
limit organic HAP emissions to no more than 3.3 kg (27.5 lb) organic HAP 
per liter (gal) coating solids used during each 12-month compliance 
period.
    (3) For each existing magnet wire coating affected source, limit 
organic HAP emissions to no more than 0.12 kg (1.0 lb) organic HAP per 
liter (gal) coating solids used during each 12-month compliance period.
    (4) For each existing rubber-to-metal coating affected source, limit 
organic HAP emissions to no more than 4.5 kg (37.7 lb) organic HAP per 
liter (gal) coating solids used during each 12-month compliance period.
    (5) For each existing extreme performance fluoropolymer coating 
affected source, limit organic HAP emissions to no more than 1.5 kg 
(12.4 lbs) organic HAP per liter (gal) coating solids used during each 
12-month compliance period.
    (c) If your facility's surface coating operations meet the 
applicability criteria of more than one of the subcategory emission 
limits specified in paragraphs (a) or (b) of this section, you may 
comply separately with each subcategory emission limit or comply using 
one of the alternatives in paragraph (c)(1) or (2) of this section.
    (1) If the general use or magnet wire surface coating operations 
subject to only one of the emission limits specified in paragraphs 
(a)(1), (3), (b)(1), or (3) of this section account for 90 percent or 
more of the surface coating activity at your facility (i.e., it is the 
predominant activity at your facility),

[[Page 563]]

then compliance with that one emission limitations in this subpart for 
all surface coating operations constitutes compliance with the other 
applicable emission limits. You must use liters (gal) of solids used as 
a measure of relative surface coating activity over a representative 
period of operation. You may estimate the relative volume of coating 
solids used from parameters other than coating consumption and volume 
solids content (e.g., design specifications for the parts or products 
coated and the number of items produced). The determination of 
predominant activity must accurately reflect current and projected 
coating operations and must be verifiable through appropriate 
documentation. The use of parameters other than coating consumption and 
volume solids content must be approved by the Administrator. You may use 
data for any reasonable time period of at least 1 year in determining 
the relative amount of coating activity, as long as they represent the 
way the source will continue to operate in the future and are approved 
by the Administrator. You must determine the predominant activity at 
your facility and submit the results of that determination with the 
initial notification required by Sec. 63.3910(b). Additionally, you 
must determine the facility's predominant activity annually and include 
the determination in the next semi-annual compliance report required by 
Sec. 63.3920(a).
    (2) You may calculate and comply with a facility-specific emission 
limit as described in paragraphs (c)(2)(i) through (iii) of this 
section. If you elect to comply using the facility-specific emission 
limit alternative, then compliance with the facility-specific emission 
limit and the emission limitations in this subpart for all surface 
coating operations constitutes compliance with this and other applicable 
surface coating NESHAP. In calculating a facility-specific emission 
limit, you must include coating activities that meet the applicability 
criteria of the other subcategories and constitute more than 1 percent 
of total coating activities. Coating activities that meet the 
applicability criteria of other surface coating NESHAP but comprise less 
than 1 percent of coating activities need not be included in the 
determination of predominant activity but must be included in the 
compliance calculation.
    (i) You are required to calculate the facility-specific emission 
limit for your facility when you submit the notification of compliance 
status required in Sec. 63.3910(c), and on a monthly basis afterward 
using the coating data for the relevant 12-month compliance period.
    (ii) Use Equation 1 of this section to calculate the facility-
specific emission limit for your surface coating operations for each 12-
month compliance period.

    (iii) If you need to convert an emission limit in another surface 
coating NESHAP from kg (lb) organic HAP per kg (lb) coating solids used 
to kg (lb) organic HAP per liter (gal) coating solids used, you must use 
the default solids density of 1.26 kg solids per liter coating solids 
(10.5 lb solids per gal solids).



Sec. 63.3891  What are my options for meeting the emission limits?

    You must include all coatings (as defined in Sec. 63.3981), 
thinners and/or other additives, and cleaning materials used in the 
affected source when determining whether the organic HAP emission rate 
is equal to or less than the applicable emission limit in Sec. 63.3890. 
To make this determination, you must use at least one of the three 
compliance options listed in paragraphs (a) through (c) of this section. 
You may apply any of the compliance options to an individual coating 
operation, or to multiple coating operations as a group, or to the 
entire affected source. You may use different compliance options for 
different coating operations, or at different times on the same coating 
operation. You may employ different compliance options when different 
coatings are applied to the same part, or when the same coating is 
applied to different parts. However, you may not use different 
compliance options at the same time on the same coating operation. If 
you switch between compliance options for any coating operation or group 
of coating operations, you must document this switch as required by 
Sec. 63.3930(c), and you must report it in the next semiannual 
compliance report required in Sec. 63.3920.
    (a) Compliant material option. Demonstrate that the organic HAP 
content of each coating used in the coating operation(s) is less than or 
equal to the applicable emission limit in Sec. 63.3890, and that each 
thinner and/or other additive, and cleaning material used contains no 
organic HAP. You must meet all the requirements of Sec. Sec. 63.3940, 
63.3941, and 63.3942 to demonstrate compliance with the applicable 
emission limit using this option.
    (b) Emission rate without add-on controls option. Demonstrate that, 
based on the coatings, thinners and/or other additives, and cleaning 
materials used in the coating operation(s), the organic HAP emission 
rate for the coating operation(s) is less than or equal to the 
applicable emission limit in Sec. 63.3890, calculated as a rolling 12-
month emission rate and determined on a monthly basis. You must meet all 
the requirements of Sec. Sec. 63.3950, 63.3951, and 63.3952 to 
demonstrate compliance with the emission limit using this option.
    (c) Emission rate with add-on controls option. Demonstrate that, 
based on the coatings, thinners and/or other additives, and cleaning 
materials used in the coating operation(s), and the emissions reductions 
achieved by emission capture systems and add-on controls, the organic 
HAP emission rate for the coating operation(s) is less than or equal to 
the applicable emission limit in Sec. 63.3890, calculated as a rolling 
12-month emission rate and determined on a monthly basis. If you use 
this compliance option, you must also demonstrate that all emission 
capture systems and add-on control devices for the coating operation(s) 
meet the operating limits required in Sec. 63.3892, except for solvent 
recovery systems for which you conduct liquid-liquid material balances 
according to Sec. 63.3961(j), and that you meet the work practice 
standards required in Sec. 63.3893. You must meet all the requirements 
of Sec. Sec. 63.3960 through 63.3968 to demonstrate compliance with the 
emission limits, operating limits, and work practice standards using 
this option.



Sec. 63.3892  What operating limits must I meet?

    (a) For any coating operation(s) on which you use the compliant 
material option or the emission rate without add-on controls option, you 
are not required to meet any operating limits.
    (b) For any controlled coating operation(s) on which you use the 
emission

[[Page 565]]

rate with add-on controls option, except those for which you use a 
solvent recovery system and conduct a liquid-liquid material balance 
according to Sec. 63.3961(j), you must meet the operating limits 
specified in Table 1 to this subpart. These operating limits apply to 
the emission capture and control systems on the coating operation(s) for 
which you use this option, and you must establish the operating limits 
during the performance test according to the requirements in Sec. 
63.3967. You must meet the operating limits at all times after you 
establish them.
    (c) If you use an add-on control device other than those listed in 
Table 1 to this subpart, or wish to monitor an alternative parameter and 
comply with a different operating limit, you must apply to the 
Administrator for approval of alternative monitoring under Sec. 
63.8(f).



Sec. 63.3893  What work practice standards must I meet?

    (a) For any coating operation(s) on which you use the compliant 
material option or the emission rate without add-on controls option, you 
are not required to meet any work practice standards.
    (b) If you use the emission rate with add-on controls option, you 
must develop and implement a work practice plan to minimize organic HAP 
emissions from the storage, mixing, and conveying of coatings, thinners 
and/or other additives, and cleaning materials used in, and waste 
materials generated by the controlled coating operation(s) for which you 
use this option; or you must meet an alternative standard as provided in 
paragraph (c) of this section. The plan must specify practices and 
procedures to ensure that, at a minimum, the elements specified in 
paragraphs (b)(1) through (5) of this section are implemented.
    (1) All organic-HAP-containing coatings, thinners and/or other 
additives, cleaning materials, and waste materials must be stored in 
closed containers.
    (2) Spills of organic-HAP-containing coatings, thinners and/or other 
additives, cleaning materials, and waste materials must be minimized.
    (3) Organic-HAP-containing coatings, thinners and/or other 
additives, cleaning materials, and waste materials must be conveyed from 
one location to another in closed containers or pipes.
    (4) Mixing vessels which contain organic-HAP-containing coatings and 
other materials must be closed except when adding to, removing, or 
mixing the contents.
    (5) Emissions of organic HAP must be minimized during cleaning of 
storage, mixing, and conveying equipment.
    (c) As provided in Sec. 63.6(g), we, the U.S. Environmental 
Protection Agency, may choose to grant you permission to use an 
alternative to the work practice standards in this section.

or 40 CFR 71.6(a)(3)(iii)(A), and the semiannual compliance report 
includes all required information concerning deviations from any 
emission limitation in this subpart, its submission will be deemed to 
satisfy any obligation to report the same deviations in the semiannual 
monitoring report. However, submission of a semiannual compliance report 
shall not otherwise affect any obligation the affected source may have 
to report deviations from permit requirements to the permitting 
authority.
    (3) General requirements. The semiannual compliance report must 
contain the information specified in paragraphs (a)(3)(i) through (vii)

        Compliance Requirements for the Compliant Material Option



Sec. 63.3940  By what date must I conduct the initial compliance
demonstration?

    You must complete the initial compliance demonstration for the 
initial compliance period according to the requirements in Sec. 
63.3941. The initial compliance period begins on the applicable 
compliance date specified in Sec. 63.3883 and ends on the last day of 
the 12th month following the compliance date. If the compliance date 
occurs on any day other than the first day of a month, then the initial 
compliance period extends through that month plus

[[Page 574]]

the next 12 months. The initial compliance demonstration includes the 
calculations according to Sec. 63.3941 and supporting documentation 
showing that during the initial compliance period, you used no coating 
with an organic HAP content that exceeded the applicable emission limit 
in Sec. 63.3890, and that you used no thinners and/or other additives, 
or cleaning materials that contained organic HAP as determined according 
to Sec. 63.3941(a).



Sec. 63.3941  How do I demonstrate initial compliance with the emission
limitations?

    You may use the compliant material option for any individual coating 
operation, for any group of coating operations in the affected source, 
or for all the coating operations in the affected source. You must use 
either the emission rate without add-on controls option or the emission 
rate with add-on controls option for any coating operation in the 
affected source for which you do not use this option. To demonstrate 
initial compliance using the compliant material option, the coating 
operation or group of coating operations must use no coating with an 
organic HAP content that exceeds the applicable emission limits in Sec. 
63.3890 and must use no thinner and/or other additive, or cleaning 
material that contains organic HAP as determined according to this 
section. Any coating operation for which you use the compliant material 
option is not required to meet the operating limits or work practice 
standards required in Sec. Sec. 63.3892 and 63.3893, respectively. You 
must conduct a separate initial compliance demonstration for each 
general use, high performance, magnet wire, rubber-to-metal, and extreme 
performance fluoropolymer coating operation unless you are demonstrating 
compliance with a predominant activity or facility-specific emission 
limit as provided in Sec. 63.3890(c). If you are demonstrating 
compliance with a predominant activity or facility-specific emission 
limit as provided in Sec. 63.3890(c), you must demonstrate that all 
coating operations included in the predominant activity determination or 
calculation of the facility-specific emission limit comply with that 
limit. You must meet all the requirements of this section. Use the 
procedures in this section on each coating, thinner and/or other 
additive, and cleaning material in the condition it is in when it is 
received from its manufacturer or supplier and prior to any alteration. 
You do not need to redetermine the organic HAP content of coatings, 
thinners and/or other additives, and cleaning materials that are 
reclaimed on-site (or reclaimed off-site if you have documentation 
showing that you received back the exact same materials that were sent 
off-site) and reused in the coating operation for which you use the 
compliant material option, provided these materials in their condition 
as received were demonstrated to comply with the compliant material 
option.
    (a) Determine the mass fraction of organic HAP for each material 
used. You must determine the mass fraction of organic HAP for each 
coating, thinner and/or other additive, and cleaning material used 
during the compliance period by using one of the options in paragraphs 
(a)(1) through (5) of this section.
    (1) Method 311 (appendix A to 40 CFR part 63). You may use Method 
311 for determining the mass fraction of organic HAP. Use the procedures 
specified in paragraphs (a)(1)(i) and (ii) of this section when 
performing a Method 311 test.
    (i) Count each organic HAP that is measured to be present at 0.1 
percent by mass or more for Occupational Safety and Health 
Administration (OSHA)-defined carcinogens as specified in 29 CFR 
1910.1200(d)(4) and at 1.0 percent by mass or more for other compounds. 
For example, if toluene (not an OSHA carcinogen) is measured to be 0.5 
percent of the material by mass, you do not have to count it. Express 
the mass fraction of each organic HAP you count as a value truncated to 
four places after the decimal point (e.g., 0.3791).
    (ii) Calculate the total mass fraction of organic HAP in the test 
material by adding up the individual organic HAP mass fractions and 
truncating the result to three places after the decimal point (e.g., 
0.763).
    (2) Method 24 (appendix A to 40 CFR part 60). For coatings, you may 
use

[[Page 575]]

Method 24 to determine the mass fraction of nonaqueous volatile matter 
and use that value as a substitute for mass fraction of organic HAP. For 
reactive adhesives in which some of the HAP react to form solids and are 
not emitted to the atmosphere, you may use the alternative method 
contained in appendix A to subpart PPPP of this part, rather than Method 
24. You may use the volatile fraction that is emitted, as measured by 
the alternative method in appendix A to subpart PPPP of this part, as a 
substitute for the mass fraction of organic HAP.
    (3) Alternative method. You may use an alternative test method for 
determining the mass fraction of organic HAP once the Administrator has 
approved it. You must follow the procedure in Sec. 63.7(f) to submit an 
alternative test method for approval.
    (4) Information from the supplier or manufacturer of the material. 
You may rely on information other than that generated by the test 
methods specified in paragraphs (a)(1) through (3) of this section, such 
as manufacturer's formulation data, if it represents each organic HAP 
that is present at 0.1 percent by mass or more for OSHA-defined 
carcinogens as specified in 29 CFR 1910.1200(d)(4) and at 1.0 percent by 
mass or more for other compounds. For example, if toluene (not an OSHA 
carcinogen) is 0.5 percent of the material by mass, you do not have to 
count it. For reactive adhesives in which some of the HAP react to form 
solids and are not emitted to the atmosphere, you may rely on 
manufacturer's data that expressly states the organic HAP or volatile 
matter mass fraction emitted. If there is a disagreement between such 
information and results of a test conducted according to paragraphs 
(a)(1) through (3) of this section, then the test method results will 
take precedence unless, after consultation, you demonstrate to the 
satisfaction of the enforcement agency that the formulation data are 
correct.
    (5) Solvent blends. Solvent blends may be listed as single 
components for some materials in data provided by manufacturers or 
suppliers. Solvent blends may contain organic HAP which must be counted 
toward the total organic HAP mass fraction of the materials. When test 
data and manufacturer's data for solvent blends are not available, you 
may use the default values for the mass fraction of organic HAP in these 
solvent blends listed in Table 3 or 4 to this subpart. If you use the 
tables, you must use the values in Table 3 for all solvent blends that 
match Table 3 entries according to the instructions for Table 3, and you 
may use Table 4 only if the solvent blends in the materials you use do 
not match any of the solvent blends in Table 3 and you know only whether 
the blend is aliphatic or aromatic. However, if the results of a Method 
311 (appendix A to 40 CFR part 63) test indicate higher values than 
those listed on Table 3 or 4 to this subpart, the Method 311 results 
will take precedence unless, after consultation, you demonstrate to the 
satisfaction of the enforcement agency that the formulation data are 
correct.
    (b) Determine the volume fraction of coating solids for each 
coating. You must determine the volume fraction of coating solids 
(liters (gal) of coating solids per liter (gal) of coating) for each 
coating used during the compliance period by a test, by information 
provided by the supplier or the manufacturer of the material, or by 
calculation, as specified in paragraphs (b)(1) through (4) of this 
section. If test results obtained according to paragraph (b)(1) of this 
section do not agree with the information obtained under paragraph 
(b)(3) or (4) of this section, the test results will take precedence 
unless, after consultation, you demonstrate to the satisfaction of the 
enforcement agency that the formulation data are correct.
    (1) ASTM Method D2697-86 (Reapproved 1998) or ASTM Method D6093-97 
(Reapproved 2003). You may use ASTM Method D2697-86 (Reapproved 1998), 
``Standard Test Method for Volume Nonvolatile Matter in Clear or 
Pigmented Coatings'' (incorporated by reference, see Sec. 63.14), or 
ASTM Method D6093-97 (Reapproved 2003), ``Standard Test Method for 
Percent Volume Nonvolatile Matter in Clear or Pigmented Coatings Using a 
Helium Gas Pycnometer'' (incorporated by reference, see Sec. 63.14), to 
determine the volume fraction of coating solids for each coating. Divide 
the nonvolatile volume percent obtained with the methods by 100 to

[[Page 576]]

calculate volume fraction of coating solids.
    (2) Alternative method. You may use an alternative test method for 
determining the solids content of each coating once the Administrator 
has approved it. You must follow the procedure in Sec. 63.7(f) to 
submit an alternative test method for approval.
    (3) Information from the supplier or manufacturer of the material. 
You may obtain the volume fraction of coating solids for each coating 
from the supplier or manufacturer.
    (4) Calculation of volume fraction of coating solids. You may 
determine the volume fraction of coating solids using Equation 1 of this 
section:
[GRAPHIC] [TIFF OMITTED] TR02JA04.003

Where:

Vs = Volume fraction of coating solids, liters (gal) coating 
          solids per liter (gal) coating.
mvolatiles = Total volatile matter content of the coating, 
          including HAP, volatile organic compounds (VOC), water, and 
          exempt compounds, determined according to Method 24 in 
          appendix A of 40 CFR part 60, grams volatile matter per liter 
          coating.
Davg = Average density of volatile matter in the coating, 
          grams volatile matter per liter volatile matter, determined 
          from test results using ASTM Method D1475-98, ``Standard Test 
          Method for Density of Liquid Coatings, Inks, and Related 
          Products'' (incorporated by reference, see Sec. 63.14), 
          information from the supplier or manufacturer of the material, 
          or reference sources providing density or specific gravity 
          data for pure materials. If there is disagreement between ASTM 
          Method D1475-98 test results and other information sources, 
          the test results will take precedence unless, after 
          consultation you demonstrate to the satisfaction of the 
          enforcement agency that the formulation data are correct.

    (c) Determine the density of each coating. Determine the density of 
each coating used during the compliance period from test results using 
ASTM Method D1475-98, ``Standard Test Method for Density of Liquid 
Coatings, Inks, and Related Products'' (incorporated by reference, see 
Sec. 63.14), information from the supplier or manufacturer of the 
material, or specific gravity data for pure chemicals. If there is 
disagreement between ASTM Method D1475-98 test results and the 
supplier's or manufacturer's information, the test results will take 
precedence unless, after consultation you demonstrate to the 
satisfaction of the enforcement agency that the formulation data are 
correct.
    (d) Determine the organic HAP content of each coating. Calculate the 
organic HAP content, kg (lb) of organic HAP emitted per liter (gal) 
coating solids used, of each coating used during the compliance period 
using Equation 2 of this section:
[GRAPHIC] [TIFF OMITTED] TR02JA04.004

Where:

Hc = Organic HAP content of the coating, kg organic HAP 
          emitted per liter (gal) coating solids used.
Dc = Density of coating, kg coating per liter (gal) coating, 
          determined according to paragraph (c) of this section.
Wc = Mass fraction of organic HAP in the coating, kg organic 
          HAP per kg coating, determined according to paragraph (a) of 
          this section.
Vs = Volume fraction of coating solids, liter (gal) coating 
          solids per liter (gal) coating, determined according to 
          paragraph (b) of this section.

    (e) Compliance demonstration. The calculated organic HAP content for 
each coating used during the initial compliance period must be less than 
or equal to the applicable emission limit in Sec. 63.3890; and each 
thinner and/or other additive, and cleaning material used during the 
initial compliance period must contain no organic HAP, determined 
according to paragraph (a) of this section. You must keep all records 
required by Sec. Sec. 63.3930 and 63.3931. As part of the notification 
of compliance status required in Sec. 63.3910, you must identify the 
coating operation(s) for which you used the compliant material option 
and submit a statement that the coating operation(s) was (were) in 
compliance with the emission limitations during the initial compliance 
period because you used no coatings for which the organic HAP content 
exceeded the applicable emission limit in Sec. 63.3890, and you used no 
thinners and/

[[Page 577]]

or other additives, or cleaning materials that contained organic HAP, 
determined according to the procedures in paragraph (a) of this section.



Sec. 63.3942  How do I demonstrate continuous compliance with the
emission limitations?

    (a) For each compliance period to demonstrate continuous compliance, 
you must use no coating for which the organic HAP content (determined 
using Equation 2 of Sec. 63.3941) exceeds the applicable emission limit 
in Sec. 63.3890, and use no thinner and/or other additive, or cleaning 
material that contains organic HAP, determined according to Sec. 
63.3941(a). A compliance period consists of 12 months. Each month, after 
the end of the initial compliance period described in Sec. 63.3940, is 
the end of a compliance period consisting of that month and the 
preceding 11 months. If you are complying with a facility-specific 
emission limit under Sec. 63.3890(c), you must also perform the 
calculation using Equation 1 in Sec. 63.3890(c)(2) on a monthly basis 
using the data from the previous 12 months of operation.
    (b) If you choose to comply with the emission limitations by using 
the compliant material option, the use of any coating, thinner and/or 
other additive, or cleaning material that does not meet the criteria 
specified in paragraph (a) of this section is a deviation from the 
emission limitations that must be reported as specified in Sec. Sec. 
63.3910(c)(6) and 63.3920(a)(5).
    (c) As part of each semiannual compliance report required by Sec. 
63.3920, you must identify the coating operation(s) for which you used 
the compliant material option. If there were no deviations from the 
applicable emission limit in Sec. 63.3890, submit a statement that the 
coating operation(s) was (were) in compliance with the emission 
limitations during the reporting period because you used no coatings for 
which the organic HAP content exceeded the applicable emission limit in 
Sec. 63.3890, and you used no thinner and/or other additive, or 
cleaning material that contained organic HAP, determined according to 
Sec. 63.3941(a).
    (d) You must maintain records as specified in Sec. Sec. 63.3930 and 
63.3931.

 Compliance Requirements for the Emission Rate Without Add-On Controls 
                                 Option



Sec. 63.3950  By what date must I conduct the initial compliance
demonstration?

    You must complete the initial compliance demonstration for the 
initial compliance period according to the requirements of Sec. 
63.3951. The initial compliance period begins on the applicable 
compliance date specified in Sec. 63.3883 and ends on the last day of 
the 12th month following the compliance date. If the compliance date 
occurs on any day other than the first day of a month, then the initial 
compliance period extends through the end of that month plus the next 12 
months. You must determine the mass of organic HAP emissions and volume 
of coating solids used each month and then calculate an organic HAP 
emission rate at the end of the initial compliance period. The initial 
compliance demonstration includes the calculations according to Sec. 
63.3951 and supporting documentation showing that during the initial 
compliance period the organic HAP emission rate was equal to or less 
than the applicable emission limit in Sec. 63.3890.



Sec. 63.3951  How do I demonstrate initial compliance with the emission
limitations?

    You may use the emission rate without add-on controls option for any 
individual coating operation, for any group of coating operations in the 
affected source, or for all the coating operations in the affected 
source. You must use either the compliant material option or the 
emission rate with add-on controls option for any coating operation in 
the affected source for which you do not use this option. To demonstrate 
initial compliance using the emission rate without add-on controls 
option, the coating operation or group of coating operations must meet 
the applicable emission limit in Sec. 63.3890, but is not required to 
meet the operating limits or work practice standards in Sec. Sec. 
63.3892 and 63.3893, respectively. You must conduct a separate initial 
compliance demonstration for each general use, magnet wire, rubber-to-

[[Page 578]]

metal, and extreme performance fluoropolymer coating operation unless 
you are demonstrating compliance with a predominant activity or 
facility-specific emission limit as provided in Sec. 63.3890(c). If you 
are demonstrating compliance with a predominant activity or facility-
specific emission limit as provided in Sec. 63.3890(c), you must 
demonstrate that all coating operations included in the predominant 
activity determination or calculation of the facility-specific emission 
limit comply with that limit. You must meet all the requirements of this 
section. When calculating the organic HAP emission rate according to 
this section, do not include any coatings, thinners and/or other 
additives, or cleaning materials used on coating operations for which 
you use the compliant material option or the emission rate with add-on 
controls option. You do not need to redetermine the mass of organic HAP 
in coatings, thinners and/or other additives, or cleaning materials that 
have been reclaimed on-site (or reclaimed off-site if you have 
documentation showing that you received back the exact same materials 
that were sent off-site) and reused in the coating operation for which 
you use the emission rate without add-on controls option. If you use 
coatings, thinners and/or other additives, or cleaning materials that 
have been reclaimed on-site, the amount of each used in a month may be 
reduced by the amount of each that is reclaimed. That is, the amount 
used may be calculated as the amount consumed to account for materials 
that are reclaimed.
    (a) Determine the mass fraction of organic HAP for each material. 
Determine the mass fraction of organic HAP for each coating, thinner 
and/or other additive, and cleaning material used during each month 
according to the requirements in Sec. 63.3941(a).
    (b) Determine the volume fraction of coating solids. Determine the 
volume fraction of coating solids (liter (gal) of coating solids per 
liter (gal) of coating) for each coating used during each month 
according to the requirements in Sec. 63.3941(b).
    (c) Determine the density of each material. Determine the density of 
each liquid coating, thinner and/or other additive, and cleaning 
material used during each month from test results using ASTM Method 
D1475-98, ``Standard Test Method for Density of Liquid Coatings, Inks, 
and Related Products'' (incorporated by reference, see Sec. 63.14), 
information from the supplier or manufacturer of the material, or 
reference sources providing density or specific gravity data for pure 
materials. If you are including powder coatings in the compliance 
determination, determine the density of powder coatings, using ASTM 
Method D5965-02, ``Standard Test Methods for Specific Gravity of Coating 
Powders'' (incorporated by reference, see Sec. 63.14), or information 
from the supplier. If there is disagreement between ASTM Method D1475-98 
or ASTM Method D5965-02 test results and other such information sources, 
the test results will take precedence unless, after consultation you 
demonstrate to the satisfaction of the enforcement agency that the 
formulation data are correct. If you purchase materials or monitor 
consumption by weight instead of volume, you do not need to determine 
material density. Instead, you may use the material weight in place of 
the combined terms for density and volume in Equations 1A, 1B, 1C, and 2 
of this section.
    (d) Determine the volume of each material used. Determine the volume 
(liters) of each coating, thinner and/or other additive, and cleaning 
material used during each month by measurement or usage records. If you 
purchase materials or monitor consumption by weight instead of volume, 
you do not need to determine the volume of each material used. Instead, 
you may use the material weight in place of the combined terms for 
density and volume in Equations 1A, 1B, and 1C of this section.
    (e) Calculate the mass of organic HAP emissions. The mass of organic 
HAP emissions is the combined mass of organic HAP contained in all 
coatings, thinners and/or other additives, and cleaning materials used 
during each month minus the organic HAP in certain waste materials. 
Calculate the mass of organic HAP emissions using Equation 1 of this 
section.

in waste materials sent or designated for shipment to a hazardous waste 
TSDF in Equation 1 of this section, then you must determine the mass 
according to paragraphs (e)(4)(i) through (iv) of this section.
    (i) You may only include waste materials in the determination that 
are generated by coating operations in the affected source for which you 
use Equation 1 of this section and that will be treated or disposed of 
by a facility that is regulated as a TSDF under 40 CFR part 262, 264,

          all following compliance periods, n equals 12).

    (h) Compliance demonstration. The organic HAP emission rate for the 
initial compliance period calculated using Equation 3 of this section 
must be less than or equal to the applicable emission limit for each 
subcategory in Sec. 63.3890 or the predominant activity or facility-
specific emission limit allowed in Sec. 63.3890(c). You must keep all 
records as required by Sec. Sec. 63.3930 and 63.3931. As part of the 
notification of compliance status required by Sec. 63.3910, you must 
identify the coating operation(s) for which you used the emission rate 
without add-on controls option and submit a statement that the coating 
operation(s) was (were) in compliance with the emission limitations 
during the initial compliance period because the organic HAP emission 
rate was less than or equal to the applicable emission limit in Sec. 
63.3890, determined according to the procedures in this section.



Sec. 63.3952  How do I demonstrate continuous compliance with the
emission limitations?

    (a) To demonstrate continuous compliance, the organic HAP emission 
rate for each compliance period, determined according to Sec. 
63.3951(a) through (g), must be less than or equal to the applicable 
emission limit in Sec. 63.3890. A compliance period consists of 12 
months. Each month after the end of the initial compliance period 
described in Sec. 63.3950 is the end of a compliance period consisting 
of that month and the preceding 11 months. You must perform the 
calculations in Sec. 63.3951(a) through (g) on a monthly basis using 
data from the previous 12 months of operation. If you are complying with 
a facility-specific emission limit under Sec. 63.3890(c), you must also 
perform the calculation using Equation 1 in Sec. 63.3890(c)(2) on a 
monthly basis using the data from the previous 12 months of operation.
    (b) If the organic HAP emission rate for any 12-month compliance 
period exceeded the applicable emission limit in Sec. 63.3890, this is 
a deviation from the

[[Page 581]]

emission limitation for that compliance period and must be reported as 
specified in Sec. Sec. 63.3910(c)(6) and 63.3920(a)(6).
    (c) As part of each semiannual compliance report required by Sec. 
63.3920, you must identify the coating operation(s) for which you used 
the emission rate without add-on controls option. If there were no 
deviations from the emission limitations, you must submit a statement 
that the coating operation(s) was (were) in compliance with the emission 
limitations during the reporting period because the organic HAP emission 
rate for each compliance period was less than or equal to the applicable 
emission limit in Sec. 63.3890, determined according to Sec. 
63.3951(a) through (g).
    (d) You must maintain records as specified in Sec. Sec. 63.3930 and 
63.3931.

   Compliance Requirements for the Emission Rate With Add-On Controls 
                                 Option



Sec. 63.3960  By what date must I conduct performance tests and 
other initial compliance demonstrations?

    (a) New and reconstructed affected sources. For a new or 
reconstructed affected source, you must meet the requirements of 
paragraphs (a)(1) through (4) of this section.
    (1) All emission capture systems, add-on control devices, and CPMS 
must be installed and operating no later than the applicable compliance 
date specified in Sec. 63.3883. Except for solvent recovery systems for 
which you conduct liquid-liquid material balances according to Sec. 
63.3961(j), you must conduct a performance test of each capture system 
and add-on control device according to Sec. Sec. 63.3964, 63.3965, and 
63.3966 and establish the operating limits required by Sec. 63.3892 no 
later than 180 days after the applicable compliance date specified in 
Sec. 63.3883. For a solvent recovery system for which you conduct 
liquid-liquid material balances according to Sec. 63.3961(j), you must 
initiate the first material balance no later than the applicable 
compliance date specified in Sec. 63.3883. For magnet wire coating 
operations you may, with approval, conduct a performance test of one 
representative magnet wire coating machine for each group of identical 
or very similar magnet wire coating machines.
    (2) You must develop and begin implementing the work practice plan 
required by Sec. 63.3893 no later than the compliance date specified in 
Sec. 63.3883.
    (3) You must complete the initial compliance demonstration for the 
initial compliance period according to the requirements of Sec. 
63.3961. The initial compliance period begins on the applicable 
compliance date specified in Sec. 63.3883 and ends on the last day of 
the 12th month following the compliance date. If the compliance date 
occurs on any day other than the first day of a month, then the initial 
compliance period extends through the end of that month plus the next 12 
months. You must determine the mass of organic HAP emissions and volume 
of coatings solids used each month and then calculate an organic HAP 
emission rate at the end of the initial compliance period. The initial 
compliance demonstration includes the results of emission capture system 
and add-on control device performance tests conducted according to 
Sec. Sec. 63.3964, 63.3965, and 63.3966; results of liquid-liquid 
material balances conducted according to Sec. 63.3961(j); calculations 
according to Sec. 63.3961 and supporting documentation showing that 
during the initial compliance period the organic HAP emission rate was 
equal to or less than the applicable emission limit in Sec. 63.3890; 
the operating limits established during the performance tests and the 
results of the continuous parameter monitoring required by Sec. 
63.3968; and documentation of whether you developed and implemented the 
work practice plan required by Sec. 63.3893.
    (4) You do not need to comply with the operating limits for the 
emission capture system and add-on control device required by Sec. 
63.3892 until after you have completed the performance tests specified 
in paragraph (a)(1) of this section. Instead, you must maintain a log 
detailing the operation and maintenance of the emission capture system, 
add-on control device, and continuous parameter monitors during the 
period between the compliance date and the performance test. You must 
begin complying with the operating limits for your affected source on 
the date you

[[Page 582]]

complete the performance tests specified in paragraph (a)(1) of this 
section. For magnet wire coating operations, you must begin complying 
with the operating limits for all identical or very similar magnet wire 
coating machines on the date you complete the performance test of a 
representative magnet wire coating machine. The requirements in this 
paragraph (a)(4) do not apply to solvent recovery systems for which you 
conduct liquid-liquid material balances according to the requirements in 
Sec. 63.3961(j).
    (b) Existing affected sources. For an existing affected source, you 
must meet the requirements of paragraphs (b)(1) through (3) of this 
section.
    (1) All emission capture systems, add-on control devices, and CPMS 
must be installed and operating no later than the applicable compliance 
date specified in Sec. 63.3883. Except for magnet wire coating 
operations and solvent recovery systems for which you conduct liquid-
liquid material balances according to Sec. 63.3961(j), you must conduct 
a performance test of each capture system and add-on control device 
according to the procedures in Sec. Sec. 63.3964, 63.3965, and 63.3966 
and establish the operating limits required by Sec. 63.3892 no later 
than the compliance date specified in Sec. 63.3883. For magnet wire 
coating operations, you may, with approval, conduct a performance test 
of a single magnet wire coating machine that represents identical or 
very similar magnet wire coating machines. For a solvent recovery system 
for which you conduct liquid-liquid material balances according to Sec. 
63.3961(j), you must initiate the first material balance no later than 
the compliance date specified in Sec. 63.3883.
    (2) You must develop and begin implementing the work practice plan 
required by Sec. 63.3893 no later than the compliance date specified in 
Sec. 63.3883.
    (3) You must complete the initial compliance demonstration for the 
initial compliance period according to the requirements of Sec. 
63.3961. The initial compliance period begins on the applicable 
compliance date specified in Sec. 63.3883 and ends on the last day of 
the 12th month following the compliance date. If the compliance date 
occurs on any day other than the first day of a month, then the initial 
compliance period extends through the end of that month plus the next 12 
months. You must determine the mass of organic HAP emissions and volume 
of coatings solids used each month and then calculate an organic HAP 
emission rate at the end of the initial compliance period. The initial 
compliance demonstration includes the results of emission capture system 
and add-on control device performance tests conducted according to 
Sec. Sec. 63.3964, 63.3965, and 63.3966; results of liquid-liquid 
material balances conducted according to Sec. 63.3961(j); calculations 
according to Sec. 63.3961 and supporting documentation showing that 
during the initial compliance period the organic HAP emission rate was 
equal to or less than the applicable emission limit in Sec. 63.3890; 
the operating limits established during the performance tests and the 
results of the continuous parameter monitoring required by Sec. 
63.3968; and documentation of whether you developed and implemented the 
work practice plan required by Sec. 63.3893.
    (c) You are not required to conduct an initial performance test to 
determine capture efficiency or destruction efficiency of a capture 
system or control device if you receive approval to use the results of a 
performance test that has been previously conducted on that capture 
system or control device. Any such previous tests must meet the 
conditions described in paragraphs (c)(1) through (3) of this section.
    (1) The previous test must have been conducted using the methods and 
conditions specified in this subpart.
    (2) Either no process or equipment changes have been made since the 
previous test was performed or the owner or operator must be able to 
demonstrate that the results of the performance test, reliably 
demonstrate compliance despite process or equipment changes.
    (3) Either the required operating parameters were established in the 
previous test or sufficient data were collected in the previous test to 
establish the required operating parameters.

[[Page 583]]



Sec. 63.3961  How do I demonstrate initial compliance?

    (a) You may use the emission rate with add-on controls option for 
any coating operation, for any group of coating operations in the 
affected source, or for all of the coating operations in the affected 
source. You may include both controlled and uncontrolled coating 
operations in a group for which you use this option. You must use either 
the compliant material option or the emission rate without add-on 
controls option for any coating operation in the affected source for 
which you do not use the emission rate with add-on controls option. To 
demonstrate initial compliance, the coating operation(s) for which you 
use the emission rate with add-on controls option must meet the 
applicable emission limitations in Sec. Sec. 63.3890, 63.3892, and 
63.3893. You must conduct a separate initial compliance demonstration 
for each general use, magnet wire, rubber-to-metal, and extreme 
performance fluoropolymer coating operation, unless you are 
demonstrating compliance with a predominant activity or facility-
specific emission limit as provided in Sec. 63.3890(c). If you are 
demonstrating compliance with a predominant activity or facility-
specific emission limit as provided in Sec. 63.4490(c), you must 
demonstrate that all coating operations included in the predominant 
activity determination or calculation of the facility-specific emission 
limit comply with that limit. You must meet all the requirements of this 
section. When calculating the organic HAP emission rate according to 
this section, do not include any coatings, thinners and/or other 
additives, or cleaning materials used on coating operations for which 
you use the compliant material option or the emission rate without add-
on controls option. You do not need to redetermine the mass of organic 
HAP in coatings, thinners and/or other additives, or cleaning materials 
that have been reclaimed onsite (or reclaimed off-site if you have 
documentation showing that you received back the exact same materials 
that were sent off-site) and reused in the coatings operation(s) for 
which you use the emission rate with add-on controls option. If you use 
coatings, thinners and/or other additives, or cleaning materials that 
have been reclaimed on-site, the amount of each used in a month may be 
reduced by the amount of each that is reclaimed. That is, the amount 
used may be calculated as the amount consumed to account for materials 
that are reclaimed.
    (b) Compliance with operating limits. Except as provided in Sec. 
63.3960(a)(4), and except for solvent recovery systems for which you 
conduct liquid-liquid material balances according to the requirements of 
paragraph (j) of this section, you must establish and demonstrate 
continuous compliance during the initial compliance period with the 
operating limits required by Sec. 63.3892, using the procedures 
specified in Sec. Sec. 63.3967 and 63.3968.
    (c) Compliance with work practice requirements. You must develop, 
implement, and document your implementation of the work practice plan 
required by Sec. 63.3893 during the initial compliance period, as 
specified in Sec. 63.3930.
    (d) Compliance with emission limits. You must follow the procedures 
in paragraphs (e) through (n) of this section to demonstrate compliance 
with the applicable emission limit in Sec. 63.3890 for each affected 
source in each subcategory.
    (e) Determine the mass fraction of organic HAP, density, volume 
used, and volume fraction of coating solids. Follow the procedures 
specified in Sec. 63.3951(a) through (d) to determine the mass fraction 
of organic HAP, density, and volume of each coating, thinner and/or 
other additive, and cleaning material used during each month; and the 
volume fraction of coating solids for each coating used during each 
month.
    (f) Calculate the total mass of organic HAP emissions before add-on 
controls. Using Equation 1 of Sec. 63.3951, calculate the total mass of 
organic HAP emissions before add-on controls from all coatings, thinners 
and/or other additives, and cleaning materials used during each month in 
the coating operation or group of coating operations for which you use 
the emission rate with add-on controls option.
    (g) Calculate the organic HAP emission reduction for each controlled 
coating operation. Determine the mass of organic

[[Page 584]]

HAP emissions reduced for each controlled coating operation during each 
month. The emission reduction determination quantifies the total organic 
HAP emissions that pass through the emission capture system and are 
destroyed or removed by the add-on control device. Use the procedures in 
paragraph (h) of this section to calculate the mass of organic HAP 
emission reduction for each controlled coating operation using an 
emission capture system and add-on control device other than a solvent 
recovery system for which you conduct liquid-liquid material balances. 
For each controlled coating operation using a solvent recovery system 
for which you conduct a liquid-liquid material balance, use the 
procedures in paragraph (j) of this section to calculate the organic HAP 
emission reduction.
    (h) Calculate the organic HAP emission reduction for each controlled 
coating operation not using liquid-liquid material balance. Use Equation 
1 of this section to calculate the organic HAP emission reduction for 
each controlled coating operation using an emission capture system and 
add-on control device other than a solvent recovery system for which you 
conduct liquid-liquid material balances. The calculation applies the 
emission capture system efficiency and add-on control device efficiency 
to the mass of organic HAP contained in the coatings, thinners and/or 
other additives, and cleaning materials that are used in the coating 
operation served by the emission capture system and add-on control 
device during each month. You must assume zero efficiency for the 
emission capture system and add-on control device for any period of time 
a deviation specified in Sec. 63.3963(c) or (d) occurs in the 
controlled coating operation, including a deviation during a period of 
startup, shutdown, or malfunction, unless you have other data indicating 
the actual efficiency of the emission capture system and add-on control 
device and the use of these data is approved by the Administrator. 
Equation 1 of this section treats the materials used during such a 
deviation as if they were used on an uncontrolled coating operation for 
the time period of the deviation.

and the work practice standards required by Sec. 63.3893.



Sec. 63.3962  [Reserved]



Sec. 63.3963  How do I demonstrate continuous compliance with the
emission limitations?

    (a) To demonstrate continuous compliance with the applicable 
emission limit in Sec. 63.3890, the organic HAP emission rate for each 
compliance period, determined according to the procedures in Sec. 
63.3961, must be equal to or less than the applicable emission limit in 
Sec. 63.3890. A compliance period consists of 12 months. Each month 
after the end of the initial compliance period described in Sec. 
63.3960 is the end of a

[[Page 590]]

compliance period consisting of that month and the preceding 11 months. 
You must perform the calculations in Sec. 63.3961 on a monthly basis 
using data from the previous 12 months of operation. If you are 
complying with a facility-specific emission limit under Sec. 
63.3890(c), you must also perform the calculation using Equation 1 in 
Sec. 63.3890(c)(2) on a monthly basis using the data from the previous 
12 months of operation.
    (b) If the organic HAP emission rate for any 12-month compliance 
period exceeded the applicable emission limit in Sec. 63.3890, this is 
a deviation from the emission limitation for that compliance period that 
must be reported as specified in Sec. Sec. 63.3910(c)(6) and 
63.3920(a)(7).
    (c) You must demonstrate continuous compliance with each operating 
limit required by Sec. 63.3892 that applies to you, as specified in 
Table 1 to this subpart, when the coating line is in operation.
    (1) If an operating parameter is out of the allowed range specified 
in Table 1 to this subpart, this is a deviation from the operating limit 
that must be reported as specified in Sec. Sec. 63.3910(c)(6) and 
63.3920(a)(7).
    (2) If an operating parameter deviates from the operating limit 
specified in Table 1 to this subpart, then you must assume that the 
emission capture system and add-on control device were achieving zero 
efficiency during the time period of the deviation, unless you have 
other data indicating the actual efficiency of the emission capture 
system and add-on control device and the use of these data is approved 
by the Administrator.
    (d) You must meet the requirements for bypass lines in Sec. 
63.3968(b) for controlled coating operations for which you do not 
conduct liquid-liquid material balances. If any bypass line is opened 
and emissions are diverted to the atmosphere when the coating operation 
is running, this is a deviation that must be reported as specified in 
Sec. Sec. 63.3910(c)(6) and 63.3920(a)(7). For the purposes of 
completing the compliance calculations specified in Sec. Sec. 
63.3961(h), you must treat the materials used during a deviation on a 
controlled coating operation as if they were used on an uncontrolled 
coating operation for the time period of the deviation as indicated in 
Equation 1 of Sec. 63.3961.
    (e) You must demonstrate continuous compliance with the work 
practice standards in Sec. 63.3893. If you did not develop a work 
practice plan, or you did not implement the plan, or you did not keep 
the records required by Sec. 63.3930(k)(8), this is a deviation from 
the work practice standards that must be reported as specified in 
Sec. Sec. 63.3910(c)(6) and 63.3920(a)(7).
    (f) As part of each semiannual compliance report required in Sec. 
63.3920, you must identify the coating operation(s) for which you used 
the emission rate with add-on controls option. If there were no 
deviations from the emission limitations, submit a statement that you 
were in compliance with the emission limitations during the reporting 
period because the organic HAP emission rate for each compliance period 
was less than or equal to the applicable emission limit in Sec. 
63.3890, and you achieved the operating limits required by Sec. 63.3892 
and the work practice standards required by Sec. 63.3893 during each 
compliance period.
    (g)-(i) [Reserved]
    (j) You must maintain records as specified in Sec. Sec. 63.3930 and 
63.3931.

conditions in this section, unless you obtain a waiver of the 
performance test according to the provisions in Sec. 63.7(h).
    (1) Representative coating operation operating conditions. You must 
conduct the performance test under representative operating conditions 
for the coating operation. Operations during periods of startup, 
shutdown, or malfunction and during periods of nonoperation do not

information that is necessary to document operating conditions during 
the test and explain why the conditions represent normal operation.
    (2) Representative emission capture system and add-on control device 
operating

[[Page 591]]

conditions. You must conduct the performance test when the emission 
capture system and add-on control device are operating at a 
representative flow rate, and the add-on control device is operating at 
a representative inlet concentration. You must record information that 
is necessary to document emission capture system and add-on control 
device operating conditions during the test and explain why the 
conditions represent normal operation.
    (b) You must conduct each performance test of an emission capture 
system according to the requirements in Sec. 63.3965. You must conduct 
each performance test of an add-on control device according to the 
requirements in Sec. 63.3966.



Sec. 63.3965  How do I determine the emission capture system efficiency?

    You must use the procedures and test methods in this section to 
determine capture efficiency as part of the performance test required by 
Sec. 63.3960.
    (a) Assuming 100 percent capture efficiency. You may assume the 
capture system efficiency is 100 percent if both of the conditions in 
paragraphs (a)(1) and (2) of this section are met:
    (1) The capture system meets the criteria in Method 204 of appendix 
M to 40 CFR part 51 for a PTE and directs all the exhaust gases from the 
enclosure to an add-on control device.
    (2) All coatings, thinners and/or other additives, and cleaning 
materials used in the coating operation are applied within the capture 
system; coating solvent flash-off, curing, and drying occurs within the 
capture system; and the removal or evaporation of cleaning materials 
from the surfaces they are applied to occurs within the capture system. 
For example, this criterion is not met if parts enter the open shop 
environment when being moved between a spray booth and a curing oven.
    (b) Measuring capture efficiency. If the capture system does not 
meet both of the criteria in paragraphs (a)(1) and (2) of this section, 
then you must use one of the three protocols described in paragraphs 
(c), (d), and (e) of this section to measure capture efficiency. The 
capture efficiency measurements use TVH capture efficiency as a 
surrogate for organic HAP capture efficiency. For the protocols in 
paragraphs (c) and (d) of this section, the capture efficiency 
measurement must consist of three test runs. Each test run must be at 
least 3 hours duration or the length of a production run, whichever is 
longer, up to 8 hours. For the purposes of this test, a production run 
means the time required for a single part to go from the beginning to 
the end of the production, which includes surface preparation activities 
and drying and curing time.
    (c) Liquid-to-uncaptured-gas protocol using a temporary total 
enclosure or building enclosure. The liquid-to-uncaptured-gas protocol 
compares the mass of liquid TVH in materials used in the coating 
operation to the mass of TVH emissions not captured by the emission 
capture system. Use a temporary total enclosure or a building enclosure 
and the procedures in paragraphs (c)(1) through (6) of this section to 
measure emission capture system efficiency using the liquid-to-
uncaptured-gas protocol.
    (1) Either use a building enclosure or construct an enclosure around 
the coating operation where coatings, thinners and/or other additives, 
and cleaning materials are applied, and all areas where emissions from 
these applied coatings and materials subsequently occur, such as flash-
off, curing, and drying areas. The areas of the coating operation where 
capture devices collect emissions for routing to an add-on control 
device, such as the entrance and exit areas of an oven or spray booth, 
must also be inside the enclosure. The enclosure must meet the 
applicable definition of a temporary total enclosure or building 
enclosure in Method 204 of appendix M to 40 CFR part 51.
    (2) Use Method 204A or 204F of appendix M to 40 CFR part 51 to 
determine the mass fraction of TVH liquid input from each coating, 
thinner and/or other additive, and cleaning material used in the coating 
operation during each capture efficiency test run. To make the 
determination, substitute TVH for each occurrence of the term VOC in the 
methods.
    (3) Use Equation 1 of this section to calculate the total mass of 
TVH liquid input from all the coatings, thinners and/or other additives, 
and cleaning

[[Page 592]]

materials used in the coating operation during each capture efficiency 
test run:
[GRAPHIC] [TIFF OMITTED] TR02JA04.023

Where:

TVHused = Mass of liquid TVH in materials used in the coating 
          operation during the capture efficiency test run, kg.
TVHi = Mass fraction of TVH in coating, thinner and/or other 
          additive, or cleaning material, i, that is used in the coating 
          operation during the capture efficiency test run, kg TVH per 
          kg material.
Voli = Total volume of coating, thinner and/or other 
          additive, or cleaning material, i, used in the coating 
          operation during the capture efficiency test run, liters.
Di = Density of coating, thinner and/or other additive, or 
          cleaning material, i, kg material per liter material.
n = Number of different coatings, thinners and/or other additives, and 
          cleaning materials used in the coating operation during the 
          capture efficiency test run.

    (4) Use Method 204D or 204E of appendix M to 40 CFR part 51 to 
measure the total mass, kg, of TVH emissions that are not captured by 
the emission capture system. They are measured as they exit the 
temporary total enclosure or building enclosure during each capture 
efficiency test run. To make the measurement, substitute TVH for each 
occurrence of the term VOC in the methods.
    (i) Use Method 204D of appendix M to 40 CFR part 51 if the enclosure 
is a temporary total enclosure.
    (ii) Use Method 204E of appendix M to 40 CFR 51 if the enclosure is 
a building enclosure. During the capture efficiency measurement, all 
organic compound emitting operations inside the building enclosure, 
other than the coating operation for which capture efficiency is being 
determined, must be shut down, but all fans and blowers must be 
operating normally.
    (5) For each capture efficiency test run, determine the percent 
capture efficiency of the emission capture system using Equation 2 of 
this section:
[GRAPHIC] [TIFF OMITTED] TR02JA04.024

Where:

CE = Capture efficiency of the emission capture system vented to the 
          add-on control device, percent.
TVHused = Total mass of TVH liquid input used in the coating 
          operation during the capture efficiency test run, kg.
TVHuncaptured = Total mass of TVH that is not captured by the 
          emission capture system and that exits from the temporary 
          total enclosure or building enclosure during the capture 
          efficiency test run, kg.

    (6) Determine the capture efficiency of the emission capture system 
as the average of the capture efficiencies measured in the three test 
runs.
    (d) Gas-to-gas protocol using a temporary total enclosure or a 
building enclosure. The gas-to-gas protocol compares the mass of TVH 
emissions captured by the emission capture system to the mass of TVH 
emissions not captured. Use a temporary total enclosure or a building 
enclosure and the procedures in paragraphs (d)(1) through (5) of this 
section to measure emission capture system efficiency using the gas-to-
gas protocol.
    (1) Either use a building enclosure or construct an enclosure around 
the coating operation where coatings, thinners and/or other additives, 
and cleaning materials are applied, and all areas where emissions from 
these applied coatings and materials subsequently

[[Page 593]]

occur, such as flash-off, curing, and drying areas. The areas of the 
coating operation where capture devices collect emissions generated by 
the coating operation for routing to an add-on control device, such as 
the entrance and exit areas of an oven or a spray booth, must also be 
inside the enclosure. The enclosure must meet the applicable definition 
of a temporary total enclosure or building enclosure in Method 204 of 
appendix M to 40 CFR part 51.
    (2) Use Method 204B or 204C of appendix M to 40 CFR part 51 to 
measure the total mass, kg, of TVH emissions captured by the emission 
capture system during each capture efficiency test run as measured at 
the inlet to the add-on control device. To make the measurement, 
substitute TVH for each occurrence of the term VOC in the methods.
    (i) The sampling points for the Method 204B or 204C measurement must 
be upstream from the add-on control device and must represent total 
emissions routed from the capture system and entering the add-on control 
device.
    (ii) If multiple emission streams from the capture system enter the 
add-on control device without a single common duct, then the emissions 
entering the add-on control device must be simultaneously measured in 
each duct and the total emissions entering the add-on control device 
must be determined.
    (3) Use Method 204D or 204E of appendix M to 40 CFR part 51 to 
measure the total mass, kg, of TVH emissions that are not captured by 
the emission capture system; they are measured as they exit the 
temporary total enclosure or building enclosure during each capture 
efficiency test run. To make the measurement, substitute TVH for each 
occurrence of the term VOC in the methods.
    (i) Use Method 204D of appendix M to 40 CFR part 51 if the enclosure 
is a temporary total enclosure.
    (ii) Use Method 204E of appendix M to 40 CFR part 51 if the 
enclosure is a building enclosure. During the capture efficiency 
measurement, all organic compound emitting operations inside the 
building enclosure, other than the coating operation for which capture 
efficiency is being determined, must be shut down, but all fans and 
blowers must be operating normally.
    (4) For each capture efficiency test run, determine the percent 
capture efficiency of the emission capture system using Equation 3 of 
this section:
[GRAPHIC] [TIFF OMITTED] TR02JA04.025

Where:

CE = Capture efficiency of the emission capture system vented to the 
          add-on control device, percent.
TVHcaptured = Total mass of TVH captured by the emission 
          capture system as measured at the inlet to the add-on control 
          device during the emission capture efficiency test run, kg.
TVHuncaptured = Total mass of TVH that is not captured by the 
          emission capture system and that exits from the temporary 
          total enclosure or building enclosure during the capture 
          efficiency test run, kg.

    (5) Determine the capture efficiency of the emission capture system 
as the average of the capture efficiencies measured in the three test 
runs.
    (e) Alternative capture efficiency protocol. As an alternative to 
the procedures specified in paragraphs (c) and (d) of this section and 
subject to the approval of the Administrator, you may determine capture 
efficiency using any other capture efficiency protocol and test methods 
that satisfy the criteria of either the DQO or LCL approach as described 
in appendix A to subpart KK of this part.



Sec. 63.3966  How do I determine the add-on control device emission
destruction or removal efficiency?

    You must use the procedures and test methods in this section to 
determine the add-on control device emission destruction or removal 
efficiency as part of the performance test required by Sec. 63.3960. 
You must conduct three test

[[Page 594]]

runs as specified in Sec. 63.7(e)(3) and each test run must last at 
least 1 hour. If the source is a magnet wire coating machine, you may 
use the procedures in section 3.0 of appendix A to this subpart as an 
alternative.
    (a) For all types of add-on control devices, use the test methods 
specified in paragraphs (a)(1) through (5) of this section.
    (1) Use Method 1 or 1A of appendix A to 40 CFR part 60, as 
appropriate, to select sampling sites and velocity traverse points.
    (2) Use Method 2, 2A, 2C, 2D, 2F, or 2G of appendix A to 40 CFR part 
60, as appropriate, to measure gas volumetric flow rate.
    (3) Use Method 3, 3A, or 3B of appendix A to 40 CFR part 60, as 
appropriate, for gas analysis to determine dry molecular weight.
    (4) Use Method 4 of appendix A to 40 CFR part 60, to determine stack 
gas moisture.
    (5) Methods for determining gas volumetric flow rate, dry molecular 
weight, and stack gas moisture must be performed, as applicable, during 
each test run.
    (b) Measure total gaseous organic mass emissions as carbon at the 
inlet and outlet of the add-on control device simultaneously, using 
either Method 25 or 25A of appendix A to 40 CFR part 60.
    (1) Use Method 25 if the add-on control device is an oxidizer and 
you expect the total gaseous organic concentration as carbon to be more 
than 50 parts per million (ppm) at the control device outlet.
    (2) Use Method 25A if the add-on control device is an oxidizer and 
you expect the total gaseous organic concentration as carbon to be 50 
ppm or less at the control device outlet.
    (3) Use Method 25A if the add-on control device is not an oxidizer.
    (c) If two or more add-on control devices are used for the same 
emission stream, then you must measure emissions at the outlet to the 
atmosphere of each device. For example, if one add-on control device is 
a concentrator with an outlet to the atmosphere for the high-volume 
dilute stream that has been treated by the concentrator, and a second 
add-on control device is an oxidizer with an outlet to the atmosphere 
for the low-volume concentrated stream that is treated with the 
oxidizer, you must measure emissions at the outlet of the oxidizer and 
the high volume dilute stream outlet of the concentrator.
    (d) For each test run, determine the total gaseous organic emissions 
mass flow rates for the inlet and the outlet of the add-on control 
device, using Equation 1 of this section. If there is more than one 
inlet or outlet to the add-on control device, you must calculate the 
total gaseous organic mass flow rate using Equation 1 of this section 
for each inlet and each outlet and then total all of the inlet emissions 
and total all of the outlet emissions:
[GRAPHIC] [TIFF OMITTED] TR02JA04.026

Where:

Mf = Total gaseous organic emissions mass flow rate, kg per 
          hour (h).
Cc = Concentration of organic compounds as carbon in the vent 
          gas, as determined by Method 25 or Method 25A, parts per 
          million by volume (ppmv), dry basis.
Qsd = Volumetric flow rate of gases entering or exiting the 
          add-on control device, as determined by Method 2, 2A, 2C, 2D, 
          2F, or 2G, dry standard cubic meters/hour (dscm/h).
0.0416 = Conversion factor for molar volume, kg-moles per cubic meter 
          (mol/m\3\) (@ 293 Kelvin (K) and 760 millimeters of mercury 
          (mmHg).

    (e) For each test run, determine the add-on control device organic 
emissions destruction or removal efficiency, using Equation 2 of this 
section:

[[Page 595]]

[GRAPHIC] [TIFF OMITTED] TR02JA04.027

Where:

DRE = Organic emissions destruction or removal efficiency of the add-on 
          control device, percent.
Mfi = Total gaseous organic emissions mass flow rate at the 
          inlet(s) to the add-on control device, using Equation 1 of 
          this section, kg/h.
Mfo = Total gaseous organic emissions mass flow rate at the 
          outlet(s) of the add-on control device, using Equation 1 of 
          this section, kg/h.

    (f) Determine the emission destruction or removal efficiency of the 
add-on control device as the average of the efficiencies determined in 
the three test runs and calculated in Equation 2 of this section.



Sec. 63.3967  How do I establish the emission capture system and
add-on control device operating limits during the performance test?

    During the performance test required by Sec. 63.3960 and described 
in Sec. Sec. 63.3964, 63.3965, and 63.3966, you must establish the 
operating limits required by Sec. 63.3892 according to this section, 
unless you have received approval for alternative monitoring and 
operating limits under Sec. 63.8(f) as specified in Sec. 63.3892.
    (a) Thermal oxidizers. If your add-on control device is a thermal 
oxidizer, establish the operating limits according to paragraphs (a)(1) 
and (2) of this section.
    (1) During the performance test, you must monitor and record the 
combustion temperature at least once every 15 minutes during each of the 
three test runs. You must monitor the temperature in the firebox of the 
thermal oxidizer or immediately downstream of the firebox before any 
substantial heat exchange occurs.
    (2) Use the data collected during the performance test to calculate 
and record the average combustion temperature maintained during the 
performance test. This average combustion temperature is the minimum 
operating limit for your thermal oxidizer.
    (b) Catalytic oxidizers. If your add-on control device is a 
catalytic oxidizer, establish the operating limits according to either 
paragraphs (b)(1) and (2) or paragraphs (b)(3) and (4) of this section. 
If the source is a magnet wire coating machine, you may use the 
procedures in section 3.0 of appendix A to this subpart as an 
alternative.
    (1) During the performance test, you must monitor and record the 
temperature just before the catalyst bed and the temperature difference 
across the catalyst bed at least once every 15 minutes during each of 
the three test runs.
    (2) Use the data collected during the performance test to calculate 
and record the average temperature just before the catalyst bed and the 
average temperature difference across the catalyst bed maintained during 
the performance test. These are the minimum operating limits for your 
catalytic oxidizer.
    (3) You must monitor the temperature at the inlet to the catalyst 
bed and implement a site-specific inspection and maintenance plan for 
your catalytic oxidizer as specified in paragraph (b)(4) of this 
section. During the performance test, you must monitor and record the 
temperature just before the catalyst bed at least once every 15 minutes 
during each of the three test runs. Use the data collected during the 
performance test to calculate and record the average temperature just 
before the catalyst bed during the performance test. This is the minimum 
operating limit for your catalytic oxidizer.
    (4) You must develop and implement an inspection and maintenance 
plan for your catalytic oxidizer(s) for which you elect to monitor 
according to paragraph (b)(3) of this section. The plan must address, at 
a minimum, the elements specified in paragraphs (b)(4)(i) through (iii) 
of this section.
    (i) Annual sampling and analysis of the catalyst activity (i.e., 
conversion

[[Page 596]]

efficiency) following the manufacturer's or catalyst supplier's 
recommended procedures. If problems are found during the catalyst 
activity test, you must replace the catalyst bed or take other 
corrective action consistent with the manufacturer's recommendations.
    (ii) Monthly external inspection of the catalytic oxidizer system, 
including the burner assembly and fuel supply lines for problems and, as 
necessary, adjust the equipment to assure proper air-to-fuel mixtures.
    (iii) Annual internal inspection of the catalyst bed to check for 
channeling, abrasion, and settling. If problems are found during the 
annual internal inspection of the catalyst, you must replace the 
catalyst bed or take other corrective action consistent with the 
manufacturer's recommendations. If the catalyst bed is replaced and is 
not of like or better kind and quality as the old catalyst then you must 
conduct a new performance test to determine destruction efficiency 
according to Sec. 63.3966. If a catalyst bed is replaced and the 
replacement catalyst is of like or better kind and quality as the old 
catalyst, then a new performance test to determine destruction 
efficiency is not required and you may continue to use the previously 
established operating limits for that catalytic oxidizer.
    (c) Regenerative carbon adsorbers. If your add-on control device is 
a regenerative carbon adsorber, establish the operating limits according 
to paragraphs (c)(1) and (2) of this section.
    (1) You must monitor and record the total regeneration desorbing gas 
(e.g., steam or nitrogen) mass flow for each regeneration cycle, and the 
carbon bed temperature after each carbon bed regeneration and cooling 
cycle for the regeneration cycle either immediately preceding or 
immediately following the performance test.
    (2) The operating limits for your regenerative carbon adsorber are 
the minimum total desorbing gas mass flow recorded during the 
regeneration cycle and the maximum carbon bed temperature recorded after 
the cooling cycle.
    (d) Condensers. If your add-on control device is a condenser, 
establish the operating limits according to paragraphs (d)(1) and (2) of 
this section.
    (1) During the performance test, you must monitor and record the 
condenser outlet (product side) gas temperature at least once every 15 
minutes during each of the three test runs.
    (2) Use the data collected during the performance test to calculate 
and record the average condenser outlet (product side) gas temperature 
maintained during the performance test. This average condenser outlet 
gas temperature is the maximum operating limit for your condenser.
    (e) Concentrators. If your add-on control device includes a 
concentrator, you must establish operating limits for the concentrator 
according to paragraphs (e)(1) through (4) of this section.
    (1) During the performance test, you must monitor and record the 
desorption concentrate stream gas temperature at least once every 15 
minutes during each of the three runs of the performance test.
    (2) Use the data collected during the performance test to calculate 
and record the average temperature. This is the minimum operating limit 
for the desorption concentrate gas stream temperature.
    (3) During the performance test, you must monitor and record the 
pressure drop of the dilute stream across the concentrator at least once 
every 15 minutes during each of the three runs of the performance test.
    (4) Use the data collected during the performance test to calculate 
and record the average pressure drop. This is the minimum operating 
limit for the dilute stream across the concentrator.
    (f) Emission capture systems. For each capture device that is not 
part of a PTE that meets the criteria of Sec. 63.3965(a), establish an 
operating limit for either the gas volumetric flow rate or duct static 
pressure, as specified in paragraphs (f)(1) and (2) of this section. The 
operating limit for a PTE is specified in Table 1 to this subpart. If 
the source is a magnet wire coating machine, you may use the procedures 
in section 2.0 of appendix A to this subpart as an alternative.
    (1) During the capture efficiency determination required by Sec. 
63.3960 and described in Sec. Sec. 63.3964 and 63.3965, you

[[Page 597]]

must monitor and record either the gas volumetric flow rate or the duct 
static pressure for each separate capture device in your emission 
capture system at least once every 15 minutes during each of the three 
test runs at a point in the duct between the capture device and the add-
on control device inlet.
    (2) Calculate and record the average gas volumetric flow rate or 
duct static pressure for the three test runs for each capture device. 
This average gas volumetric flow rate or duct static pressure is the 
minimum operating limit for that specific capture device.



Sec. 63.3968  What are the requirements for continuous parameter
monitoring system installation, operation, and maintenance?

    (a) General. You must install, operate, and maintain each CPMS 
specified in paragraphs (c), (e), (f), and (g) of this section according 
to paragraphs (a)(1) through (6) of this section. You must install, 
operate, and maintain each CPMS specified in paragraphs (b) and (d) of 
this section according to paragraphs (a)(3) through (5) of this section.
    (1) The CPMS must complete a minimum of one cycle of operation for 
each successive 15-minute period. You must have a minimum of four 
equally spaced successive cycles of CPMS operation in 1 hour.
    (2) You must determine the average of all recorded readings for each 
successive 3-hour period of the emission capture system and add-on 
control device operation.
    (3) You must record the results of each inspection, calibration, and 
validation check of the CPMS.
    (4) You must maintain the CPMS at all times and have available 
necessary parts for routine repairs of the monitoring equipment.
    (5) You must operate the CPMS and collect emission capture system 
and add-on control device parameter data at all times that a controlled 
coating operation is operating, except during monitoring malfunctions, 
associated repairs, and required quality assurance or control activities 
(including, if applicable, calibration checks and required zero and span 
adjustments).
    (6) You must not use emission capture system or add-on control 
device parameter data recorded during monitoring malfunctions, 
associated repairs, out-of-control periods, or required quality 
assurance or control activities when calculating data averages. You must 
use all the data collected during all other periods in calculating the 
data averages for determining compliance with the emission capture 
system and add-on control device operating limits.
    (7) A monitoring malfunction is any sudden, infrequent, not 
reasonably preventable failure of the CPMS to provide valid data. 
Monitoring failures that are caused in part by poor maintenance or 
careless operation are not malfunctions. Any period for which the 
monitoring system is out-of-control and data are not available for 
required calculations is a deviation from the monitoring requirements.
    (b) Capture system bypass line. You must meet the requirements of 
paragraphs (b)(1) and (2) of this section for each emission capture 
system that contains bypass lines that could divert emissions away from 
the add-on control device to the atmosphere.
    (1) You must monitor or secure the valve or closure mechanism 
controlling the bypass line in a nondiverting position in such a way 
that the valve or closure mechanism cannot be opened without creating a 
record that the valve was opened. The method used to monitor or secure 
the valve or closure mechanism must meet one of the requirements 
specified in paragraphs (b)(1)(i) through (v) of this section.
    (i) Flow control position indicator. Install, calibrate, maintain, 
and operate according to the manufacturer's specifications a flow 
control position indicator that takes a reading at least once every 15 
minutes and provides a record indicating whether the emissions are 
directed to the add-on control device or diverted from the add-on 
control device. The time of occurrence and flow control position must be 
recorded, as well as every time the flow direction is changed. The flow 
control position indicator must be installed at the entrance to any 
bypass line that could divert the emissions away from the add-on control 
device to the atmosphere.
    (ii) Car-seal or lock-and-key valve closures. Secure any bypass line 
valve in

[[Page 598]]

the closed position with a car-seal or a lock-and-key type 
configuration. You must visually inspect the seal or closure mechanism 
at least once every month to ensure that the valve is maintained in the 
closed position, and the emissions are not diverted away from the add-on 
control device to the atmosphere.
    (iii) Valve closure monitoring. Ensure that any bypass line valve is 
in the closed (nondiverting) position through monitoring of valve 
position at least once every 15 minutes. You must inspect the monitoring 
system at least once every month to verify that the monitor will 
indicate valve position.
    (iv) Automatic shutdown system. Use an automatic shutdown system in 
which the coating operation is stopped when flow is diverted by the 
bypass line away from the add-on control device to the atmosphere when 
the coating operation is running. You must inspect the automatic 
shutdown system at least once every month to verify that it will detect 
diversions of flow and shut down the coating operation.
    (v) Flow direction indicator. Install, calibrate, maintain, and 
operate according to the manufacturer's specifications a flow direction 
indicator that takes a reading at least once every 15 minutes and 
provides a record indicating whether the emissions are directed to the 
add-on control device or diverted from the add-on control device. Each 
time the flow direction changes, the next reading of the time of 
occurrence and flow direction must be recorded. The flow direction 
indicator must be installed in each bypass line or air makeup supply 
line that could divert the emissions away from the add-on control device 
to the atmosphere.
    (2) If any bypass line is opened, you must include a description of 
why the bypass line was opened and the length of time it remained open 
in the semiannual compliance reports required in Sec. 63.3920.
    (c) Thermal oxidizers and catalytic oxidizers. If you are using a 
thermal oxidizer or catalytic oxidizer as an add-on control device 
(including those used with concentrators or with carbon adsorbers to 
treat desorbed concentrate streams), you must comply with the 
requirements in paragraphs (c)(1) through (3) of this section:
    (1) For a thermal oxidizer, install a gas temperature monitor in the 
firebox of the thermal oxidizer or in the duct immediately downstream of 
the firebox before any substantial heat exchange occurs.
    (2) For a catalytic oxidizer, install gas temperature monitors 
upstream and/or downstream of the catalyst bed as required in Sec. 
63.3967(b).
    (3) For all thermal oxidizers and catalytic oxidizers, you must meet 
the requirements in paragraphs (a) and (c)(3)(i) through (v) of this 
section for each gas temperature monitoring device.
    (i) Locate the temperature sensor in a position that provides a 
representative temperature.
    (ii) Use a temperature sensor with a measurement sensitivity of 5 
degrees Fahrenheit or 1.0 percent of the temperature value, whichever is 
larger.
    (iii) Before using the sensor for the first time or when relocating 
or replacing the sensor, perform a validation check by comparing the 
sensor output to a calibrated temperature measurement device or by 
comparing the sensor output to a simulated temperature.
    (iv) Conduct an accuracy audit every quarter and after every 
deviation. Accuracy audit methods include comparisons of sensor output 
to redundant temperature sensors, to calibrated temperature measurement 
devices, or to temperature simulation devices.
    (v) Conduct a visual inspection of each sensor every quarter if 
redundant temperature sensors are not used.

Sec. 63.3981  What definitions apply to this subpart?

    Terms used in this subpart are defined in the CAA, in 40 CFR 63.2, 
and in this section as follows:
    Additive means a material that is added to a coating after purchase 
from a supplier (e.g., catalysts, activators, accelerators).
    Add-on control means an air pollution control device, such as a 
thermal oxidizer or carbon adsorber, that reduces pollution in an air 
stream by destruction or removal before discharge to the atmosphere.
    Adhesive, adhesive coating means any chemical substance that is 
applied for the purpose of bonding two surfaces together. Products used 
on humans and animals, adhesive tape, contact paper, or any other 
product with an adhesive incorporated onto or in an inert substrate 
shall not be considered adhesives under this subpart.
    Assembled on-road vehicle coating means any coating operation in 
which coating is applied to the surface of some component or surface of 
a fully assembled motor vehicle or trailer intended for on-road use 
including, but not limited to, components or surfaces on automobiles and 
light-duty trucks that have been repaired after a collision or otherwise 
repainted, fleet delivery trucks, and motor homes and other recreational 
vehicles (including camping trailers and fifth wheels). Assembled on-
road vehicle coating includes the concurrent coating of parts of the 
assembled on-road vehicle that are painted off-vehicle to protect 
systems, equipment, or to allow full coverage. Assembled on-road vehicle 
coating does not include surface coating operations that meet the 
applicability criteria of the automobiles and light-duty trucks NESHAP. 
Assembled on-road vehicle coating also does not include the use of 
adhesives, sealants, and caulks used in assembling on-road vehicles.
    Capture device means a hood, enclosure, room, floor sweep, or other 
means of containing or collecting emissions and directing those 
emissions into an add-on air pollution control device.
    Capture efficiency or capture system efficiency means the portion 
(expressed as a percentage) of the pollutants from an emission source 
that is delivered to an add-on control device.
    Capture system means one or more capture devices intended to collect 
emissions generated by a coating operation in the use of coatings or 
cleaning materials, both at the point of application and at subsequent 
points where emissions from the coatings and cleaning materials occur, 
such as flashoff, drying, or curing. As used in this subpart, multiple 
capture devices that collect emissions generated by a coating operation 
are considered a single capture system.

[[Page 601]]

    Cleaning material means a solvent used to remove contaminants and 
other materials, such as dirt, grease, oil, and dried or wet coating 
(e.g., depainting or paint stripping), from a substrate before or after 
coating application or from equipment associated with a coating 
operation, such as spray booths, spray guns, racks, tanks, and hangers. 
Thus, it includes any cleaning material used on substrates or equipment 
or both.
    Coating means a material applied to a substrate for decorative, 
protective, or functional purposes. Such materials include, but are not 
limited to, paints, sealants, liquid plastic coatings, caulks, inks, 
adhesives, and maskants. Decorative, protective, or functional materials 
that consist only of protective oils for metal, acids, bases, or any 
combination of these substances, or paper film or plastic film which may 
be pre-coated with an adhesive by the film manufacturer, are not 
considered coatings for the purposes of this subpart. A liquid plastic 
coating means a coating made from fine particle-size polyvinyl chloride 
(PVC) in solution (also referred to as a plastisol).
    Coating operation means equipment used to apply cleaning materials 
to a substrate to prepare it for coating application (surface 
preparation) or to remove dried coating; to apply coating to a substrate 
(coating application) and to dry or cure the coating after application; 
or to clean coating operation equipment (equipment cleaning). A single 
coating operation may include any combination of these types of 
equipment, but always includes at least the point at which a given 
quantity of coating or cleaning material is applied to a given part and 
all subsequent points in the affected source where organic HAP are 
emitted from the specific quantity of coating or cleaning material on 
the specific part. There may be multiple coating operations in an 
affected source. Coating application with handheld, non-refillable 
aerosol containers, touch-up markers, or marking pens is not a coating 
operation for the purposes of this subpart.
    Coatings solids means the nonvolatile portion of the coating that 
makes up the dry film.
    Continuous parameter monitoring system (CPMS) means the total 
equipment that may be required to meet the data acquisition and 
availability requirements of this subpart, used to sample, condition (if 
applicable), analyze, and provide a record of coating operation, or 
capture system, or add-on control device parameters.
    Controlled coating operation means a coating operation from which 
some or all of the organic HAP emissions are routed through an emission 
capture system and add-on control device.
    Deviation means any instance in which an affected source subject to 
this subpart, or an owner or operator of such a source:
    (1) Fails to meet any requirement or obligation established by this 
subpart including but not limited to, any emission limit or operating 
limit or work practice standard;
    (2) Fails to meet any term or condition that is adopted to implement 
an applicable requirement in this subpart and that is included in the 
operating permit for any affected source required to obtain such a 
permit; or
    (3) Fails to meet any emission limit, or operating limit, or work 
practice standard in this subpart during startup, shutdown, or 
malfunction, regardless of whether or not such failure is permitted by 
this subpart.
    Emission limitation means the aggregate of all requirements 
associated with a compliance option including emission limit, operating 
limit, work practice standard, etc.
    Enclosure means a structure that surrounds a source of emissions and 
captures and directs the emissions to an add-on control device.
    Exempt compound means a specific compound that is not considered a 
VOC due to negligible photochemical reactivity. The exempt compounds are 
listed in 40 CFR 51.100(s).
    Extreme performance fluoropolymer coating means coatings that are 
formulated systems based on fluoropolymer resins which often contain 
bonding matrix polymers dissolved in non-aqueous solvents as well as 
other ingredients. Extreme performance fluoropolymer coatings are 
typically used when one or more critical performance criteria are 
required including, but not limited to a

[[Page 602]]

nonstick low-energy surface, dry film lubrication, high resistance to 
chemical attack, extremely wide operating temperature, high electrical 
insulating properties, or that the surface comply with government (e.g., 
USDA, FDA) or third party specifications for health, safety, 
reliability, or performance. Once applied to a substrate, extreme 
performance fluoropolymer coatings undergo a curing process that 
typically requires high temperatures, a chemical reaction, or other 
specialized technology.
    Facility maintenance means the routine repair or renovation 
(including the surface coating) of the tools, equipment, machinery, and 
structures that comprise the infrastructure of the affected facility and 
that are necessary for the facility to function in its intended 
capacity.
    General use coating means any material that meets the definition of 
coating but does not meet the definition of high performance coating, 
rubber-to-metal coating, magnet wire coating, or extreme performance 
fluoropolymer coating as defined in this section.
    High performance architectural coating means any coating applied to 
architectural subsections which is required to meet the specifications 
of Architectural Aluminum Manufacturer's Association's publication 
number AAMA 605.2-2000.
    High performance coating means any coating that meets the definition 
of high performance architectural coating or high temperature coating in 
this section.
    High temperature coating means any coating applied to a substrate 
which during normal use must withstand temperatures of at least 538

affected source, that is used exclusively for personal, noncommercial 
purposes by the affected source's employees or assigned personnel.
    Magnet wire coatings, commonly referred to as magnet wire enamels, 
are applied to a continuous strand of wire which will be used to make 
turns (windings) in electrical devices such as coils, transformers, or 
motors. Magnet wire coatings provide high dielectric strength and turn-
to-turn conductor insulation. This allows the turns of an electrical 
device to be placed in close proximity to one another which leads to 
increased coil effectiveness and electrical efficiency.
    Magnet wire coating machine means equipment which applies and cures 
magnet wire coatings.
    Manufacturer's formulation data means data on a material (such as a 
coating) that are supplied by the material manufacturer based on 
knowledge of the ingredients used to manufacture that material, rather 
than based on testing of the material with the test methods specified in 
Sec. 63.3941. Manufacturer's formulation data may include, but are not 
limited to, information on density, organic HAP content, volatile 
organic matter content, and coating solids content.
    Mass fraction of organic HAP means the ratio of the mass of organic 
HAP to the mass of a material in which it is contained, expressed as kg 
of organic HAP per kg of material.
    Month means a calendar month or a pre-specified period of 28 days to 
35 days to allow for flexibility in recordkeeping when data are based on 
a business accounting period.
    Non-HAP coating means, for the purposes of this subpart, a coating 
that contains no more than 0.1 percent by mass of any individual organic 
HAP that is an OSHA-defined carcinogen as specified in 29 CFR 
1910.1200(d)(4) and no more than 1.0 percent by mass for any other 
individual HAP.
    Organic HAP content means the mass of organic HAP emitted per volume 
of coating solids used for a coating calculated using Equation 2 of 
Sec. 63.3941. The organic HAP content is determined for the coating in 
the condition it is in when received from its manufacturer or supplier 
and does not account for any alteration after receipt. For reactive 
adhesives in which some of the HAP react to form solids and are not 
emitted to the atmosphere, organic HAP content is the mass of organic 
HAP that is emitted, rather than the organic HAP content of the coating 
as it is received.
    Permanent total enclosure (PTE) means a permanently installed 
enclosure that

[[Page 603]]

meets the criteria of Method 204 of appendix M, 40 CFR part 51, for a 
PTE and that directs all the exhaust gases from the enclosure to an add-
on control device.
    Personal watercraft means a vessel (boat) which uses an inboard 
motor powering a water jet pump as its primary source of motive power 
and which is designed to be operated by a person or persons sitting, 
standing, or kneeling on the vessel, rather than in the conventional 
manner of sitting or standing inside the vessel.
    Protective oil means an organic material that is applied to metal 
for the purpose of providing lubrication or protection from corrosion 
without forming a solid film. This definition of protective oil 
includes, but is not limited to, lubricating oils, evaporative oils 
(including those that evaporate completely), and extrusion oils. 
Protective oils used on miscellaneous metal parts and products include 
magnet wire lubricants and soft temporary protective coatings that are 
removed prior to installation or further assembly of a part or 
component.
    Reactive adhesive means adhesive systems composed, in part, of 
volatile monomers that react during the adhesive curing reaction, and, 
as a result, do not evolve from the film during use. These volatile 
components instead become integral parts of the adhesive through 
chemical reaction. At least 70 percent of the liquid components of the 
system, excluding water, react during the process.
    Research or laboratory facility means a facility whose primary 
purpose is for research and development of new processes and products, 
that is conducted under the close supervision of technically trained 
personnel, and is not engaged in the manufacture of final or 
intermediate products for commercial purposes, except in a de minimis 
manner.
    Responsible official means responsible official as defined in 40 CFR 
70.2.
    Rubber-to-metal coatings are coatings that contain heat-activated 
polymer systems in either solvent or water that, when applied to metal 
substrates, dry to a non-tacky surface and react chemically with the 
rubber and metal during a vulcanization process.
    Startup, initial means the first time equipment is brought online in 
a facility.
    Surface preparation means use of a cleaning material on a portion of 
or all of a substrate. This includes use of a cleaning material to 
remove dried coating, which is sometimes called depainting.

purpose of measuring the capture efficiency of pollutants emitted from a 
given source as defined in Method 204 of appendix M, 40 CFR part 51.
    Thinner means an organic solvent that is added to a coating after 
the coating is received from the supplier.
    Total volatile hydrocarbon (TVH) means the total amount of 
nonaqueous volatile organic matter determined according to Methods 204 
and 204A through 204F of appendix M to 40 CFR part 51 and substituting 
the term TVH each place in the methods where the term VOC is used. The 
TVH includes both VOC and non-VOC.
    Uncontrolled coating operation means a coating operation from which 
none of the organic HAP emissions are routed through an emission capture 
system and add-on control device.
    Volatile organic compound (VOC) means any compound defined as VOC in 
40 CFR 51.100(s).
    Volume fraction of coating solids means the ratio of the volume of 
coating solids (also known as the volume of nonvolatiles) to the volume 
of a coating in which it is contained; liters (gal) of coating solids 
per liter (gal) of coating.

    Sec. Appendix A to Subpart MMMM of Part 63--Alternative Capture 
    Efficiency and Destruction Efficiency Measurement and Monitoring 
              Procedures for Magnet Wire Coating Operations

    1.0 Introduction.
    1.1 These alternative procedures for capture efficiency and 
destruction efficiency measurement and monitoring are intended 
principally for newer magnet wire coating machines where the control 
device is internal and integral to the oven so that it is difficult or 
infeasible to make gas measurements at the inlet to the control device.
    1.2 In newer gas fired magnet wire ovens with thermal control (no 
catalyst), the burner tube serves as the control device (thermal 
oxidizer) for the process. The combustion of solvents in the burner tube 
is the principal source of heat for the oven.
    1.3 In newer magnet wire ovens with a catalyst there is either a 
burner tube (gas fired ovens) or a tube filled with electric heating 
elements (electric heated oven) before the catalyst. A large portion of 
the solvent is often oxidized before reaching the catalyst. The 
combustion of solvents in the tube and across the catalyst is the 
principal source of heat for the oven. The internal catalyst in these 
ovens cannot be accessed without disassembly of the oven. This 
disassembly includes removal of the oven insulation. Oven reassembly 
often requires the installation of new oven insulation.
    1.4 Some older magnet wire ovens have external afterburners. A 
significant portion of the solvent is oxidized within these ovens as 
well.
    1.5 The alternative procedure for destruction efficiency determines 
the organic carbon content of the volatiles entering the control device 
based on the quantity of coating used, the carbon content of the 
volatile portion of the coating and the efficiency of the capture 
system. The organic carbon content of the control device outlet (oven 
exhaust for ovens without an external afterburner) is determined using 
Method 25 or 25A.
    1.6 When it is difficult or infeasible to make gas measurements at 
the inlet to the control device, measuring capture efficiency with a 
gas-to-gas protocol (see Sec. 63.3965(d)) which relies on direct 
measurement of the captured gas stream will also be difficult or 
infeasible. In these situations, capture efficiency measurement is more 
appropriately done with a procedure which does not rely on direct 
measurement of the captured gas stream.
    1.7 Magnet wire ovens are relatively small compared to many other 
coating ovens. The exhaust rate from an oven is low and varies as the 
coating use rate and solvent loading rate change from job to job. The 
air balance in magnet wire ovens is critical to product quality. Magnet 
wire ovens must be operated under negative pressure to avoid smoke and 
odor in the workplace, and the exhaust rate must be sufficient to 
prevent over heating within the oven.
    1.8 The liquid and gas measurements needed to determine capture 
efficiency and control device efficiency using these alternative 
procedures may be made simultaneously.
    1.9 Magnet wire facilities may have many (e.g., 20 to 70 or more) 
individual coating lines each with its own capture and control system. 
With approval, representative capture efficiency and control device 
efficiency testing of one magnet wire coating machine out of a group of 
identical or very similar magnet wire coating machines may be performed 
rather than testing every individual magnet wire coating machine. The 
operating parameters must be established for each tested magnet wire 
coating machine during each capture efficiency test and each control 
device efficiency test. The operating parameters established for each 
tested magnet wire

[[Page 610]]

coating machine also serve as the operating parameters for untested or 
very similar magnet wire coating machines represented by a tested magnet 
wire coating machine.
    2.0 Capture Efficiency.
    2.1 If the capture system is a permanent total enclosure as 
described in Sec. 63.3965(a), then its capture efficiency may be 
assumed to be 100 percent.
    2.2 If the capture system is not a permanent total enclosure, then 
capture efficiency must be determined using the liquid-to-uncaptured-gas 
protocol using a temporary total enclosure or building enclosure in 
Sec. 63.3965(c), or an alternative capture efficiency protocol (see 
Sec. 63.3965(e)) which does not rely on direct measurement of the 
captured gas stream.
    2.3 As an alternative to establishing and monitoring the capture 
efficiency operating parameters in Sec. 63.3967(f), the monitoring 
described in either section 2.4 or 2.5, and the monitoring described in 
sections 2.6 and 2.7 may be used for magnet wire coating machines.
    2.4 Each magnet wire oven must be equipped with an interlock 
mechanism which will stop or prohibit the application of coating either 
when any exhaust fan for that oven is not operating or when the oven 
experiences an over limit temperature condition.
    2.5 Each magnet wire oven must be equipped with an alarm which will 
be activated either when any oven exhaust fan is not operating or when 
the oven experiences an over limit temperature condition.
    2.6 If the interlock in 2.4 or the alarm in 2.5 is monitoring for 
over limit temperature conditions, then the temperature(s) that will 
trigger the interlock or the alarm must be included in the start-up, 
shutdown and malfunction plan and the interlock or alarm must be set to 
be activated when the oven reaches that temperature.
    2.7 Once every 6 months, each magnet wire oven must be checked using 
a smoke stick or equivalent approach to confirm that the oven is 
operating at negative pressure compared to the surrounding atmosphere.
    3.0 Control Device Efficiency.
    3.1 Determine the weight fraction carbon content of the volatile 
portion of each coating, thinner, additive, or cleaning material used 
during each test run using either the procedure in section 3.2 or 3.3.
    3.2 Following the procedures in Method 204F, distill a sample of 
each coating, thinner, additive, or cleaning material used during each 
test run to separate the volatile portion. Determine the weight fraction 
carbon content of each distillate using ASTM Method D5291-02, ``Standard 
Test Methods for Instrumental Determination of Carbon, Hydrogen, and 
Nitrogen in Petroleum Products and Lubricants'' (incorporated by 
reference, see Sec. 63.14).
    3.3 Analyze each coating, thinner, additive or cleaning material 
used during each test run using Method 311. For each volatile compound 
detected in the gas chromatographic analysis of each coating, thinner, 
additive, or cleaning material calculate the weight fraction of that 
whole compound in the coating, thinner, additive, or cleaning material. 
For each volatile compound detected in the gas chromatographic analysis 
of each coating, thinner, additive, or cleaning material calculate the 
weight fraction of the carbon in that compound in the coating, thinner, 
additive, or cleaning material. Calculate the weight fraction carbon 
content of each coating, thinner, additive, or cleaning material as the 
ratio of the sum of the carbon weight fractions divided by the sum of 
the whole compound weight fractions.
    3.4 Determine the mass fraction of total volatile hydrocarbon 
(TVHi) in each coating, thinner, additive, or cleaning 
material, i, used during each test run using Method 24. The mass 
fraction of total volatile hydrocarbon equals the weight fraction 
volatile matter (Wv in Method 24) minus the weight fraction 
water (Ww in Method 24), if any, present in the coating. The 
ASTM Method D6053-00, ``Standard Test Method for Determination of 
Volatile Organic Compound (VOC) Content of Electrical Insulating 
Varnishes'' (incorporated by reference, see Sec. 63.14), may be used as 
an alternative to Method 24 for magnet wire enamels. The specimen size 
for testing magnet wire enamels with ASTM Method D6053-00 must be 2.0 
0.1 grams.
    3.5 Determine the volume (VOLi) or mass 
(MASSi) of each coating, thinner, additive, or cleaning 
material, i, used during each test run.
    3.6 Calculate the total volatile hydrocarbon input 
(TVHCinlet) to the control device during each test run, as 
carbon, using Equation 1:
[GRAPHIC] [TIFF OMITTED] TR02JA04.028


[[Page 611]]


where:

TVHi = Mass fraction of TVH in coating, thinner, additive, or 
          cleaning material, i, used in the coating operation during the 
          test run.
VOLi = Volume of coating, thinner, additive, or cleaning 
          material, i, used in the coating operation during the test 
          run, liters.
Di = Density of coating, thinner, additive, or cleaning 
          material, i, used in the coating operation during the test 
          run, kg per liter.
CDi = Weight fraction carbon content of the distillate from 
          coating, thinner, additive, or cleaning material, i, used in 
          the coating operation during the test run, percent.
n = Number of coating, thinner, additive, and cleaning materials used in 
          the coating operation during the test run.

    3.7 If the mass, MASSi, of each coating, solvent, 
additive, or cleaning material, i, used during the test run is measured 
directly then MASSi can be substituted for VOLi x 
Di in Equation 1 in section 3.6.
    3.8 Determine the TVHC output (TVHCoutlet) from the 
control device, as carbon, during each test run using the methods in 
Sec. 63.3966(a) and the procedure for determining Mfo in 
Sec. 63.3966(d). TVHCoutlet equals Mfo times the 
length of the test run in hours.
    3.9 Determine the control device efficiency (DRE) for each test run 
using Equation 2:
[GRAPHIC] [TIFF OMITTED] TR02JA04.029

    3.10 The efficiency of the control device is the average of the 
three individual test run values determined in section 3.9.
    3.11 As an alternative to establishing and monitoring the 
destruction efficiency operating parameters for catalytic oxidizers in 
Sec. 63.3967(b), the monitoring described in sections 3.12 and 3.13 may 
be used for magnet wire coating machines equipped with catalytic 
oxidizers.
    3.12 During the performance test, you must monitor and record the 
temperature either just before or just after the catalyst bed at least 
once every 15 minutes during each of the three test runs. Use the data 
collected during the performance test to calculate and record the 
average temperature either just before or just after the catalyst bed 
during the performance test. This is the minimum operating limit for 
your catalytic oxidizer and for the catalytic oxidizers in identical or 
very similar magnet wire coating machines represented by the tested 
magnet wire coating machine.
    3.13 You must develop and implement an inspection and maintenance 
plan for your catalytic oxidizer(s). The plan must address, at a 
minimum, the elements specified in sections 3.14 and 3.15, and the 
elements specified in either (a) section 3.16 or (b) sections 3.17 and 
3.18.
    3.14 You must conduct a monthly external inspection of each 
catalytic oxidizer system, including the burner assembly and fuel supply 
lines for problems and, as necessary, adjust the equipment to assure 
proper air-to-fuel mixtures.
    3.15 You must conduct an annual internal inspection of each 
accessible catalyst bed to check for channeling, abrasion, and settling. 
If problems are found, you must replace the catalyst bed or take 
corrective action consistent with the manufacturer's recommendations. 
This provision does not apply to internal catalysts which cannot be 
accessed without disassembling the magnet wire oven.
    3.16 You must take a sample of each catalyst bed and perform an 
analysis of the catalyst activity (i.e., conversion efficiency) 
following the manufacturer's or catalyst supplier's recommended 
procedures. This sampling and analysis must be done within the time 
period shown in Table 1 below of the most recent of the last catalyst 
activity test or the last catalyst replacement. For example, if the 
warranty for the catalyst is 3 years and the catalyst was more recently 
replaced then the sampling and analysis must be done within the earlier 
of 26,280 operating hours or 5 calendar years of the last catalyst 
replacement. If the warranty for the catalyst is 3 years and the 
catalyst was more recently tested then the sampling and analysis must be 
done within the earlier of 13,140 operating hours or 3 calendar years of 
the last catalyst activity test. If problems are found during the 
catalyst activity test, you must replace the catalyst bed or take 
corrective action consistent with the manufacturer's recommendations.

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

    3.17 During the performance test, you must determine the average 
concentration of organic compounds as carbon in the magnet wire oven 
exhaust stack gases (Cc in Equation 1 in Sec. 63.3966(d)) 
and the destruction efficiency of the catalytic oxidizer, and calculate 
the operating limit for oven exhaust stack gas concentration as follows. 
You must identify the highest organic HAP content coating used on this 
magnet wire coating machine or any identical or very similar magnet wire 
coating machines to which the same destruction efficiency test results 
will be applied. Calculate the percent emission reduction necessary to 
meet the magnet wire coating emission limit when using this coating. 
Calculate the average concentration of organic compounds as carbon in 
the magnet wire oven exhaust stack gases that would be equivalent to 
exactly meeting the magnet wire coating emissions limit when using the 
highest organic HAP content coating. The maximum operating limit for 
oven exhaust stack gas concentration equals 90 percent of this 
calculated concentration.
    3.18 For each magnet wire coating machine equipped with a catalytic 
oxidizer you must perform an annual 10 minute test of the oven exhaust 
stack gases using EPA Method 25A. This test must be performed under 
steady state operating conditions similar to those at which the last 
destruction efficiency test for equipment of that type (either the 
specific magnet wire coating machine or an identical or very similar 
magnet wire coating machine) was conducted. If the average exhaust stack 
gas concentration during the annual test of a magnet wire coating 
machine equipped with a catalytic oxidizer is greater than the operating 
limit established in section 3.17 then that is a deviation from the 
operating limit for that catalytic oxidizer. If problems are found 
during the annual 10-minute test of the oven exhaust stack gases, you 
must replace the catalyst bed or take other corrective action consistent 
with the manufacturer's recommendations.
    3.19 If a catalyst bed is replaced and the replacement catalyst is 
not of like or better kind and quality as the old catalyst, then you 
must conduct a new performance test to determine destruction efficiency 
according to Sec. 63.3966 and establish new operating limits for that 
catalytic oxidizer unless destruction efficiency test results and 
operating limits for an identical or very similar unit (including 
consideration of the replacement catalyst) are available and approved 
for use for the catalytic oxidizer with the replacement catalyst.
    3.20 If a catalyst bed is replaced and the replacement catalyst is 
of like or better kind and quality as the old catalyst, then a new 
performance test to determine destruction efficiency is not required and 
you may continue to use the previously established operating limits for 
that catalytic oxidizer.



 Subpart NNNN_National Emission Standards for Hazardous Air Pollutants: 
                   Surface Coating of Large Appliances

    Source: 67 FR 48262, July 23, 2002, unless otherwise noted.

                        What This Subpart Covers



Sec. 63.4080  What is the purpose of this subpart?

    This subpart establishes national emission standards for hazardous 
air pollutants for large appliance surface coating facilities. This 
subpart also establishes requirements to demonstrate initial and 
continuous compliance with the emission limitations.



Sec. 63.4081  Am I subject to this subpart?

    (a) You are subject to this subpart if you own or operate a facility 
that applies coatings to large appliance parts

[[Page 613]]

or products, and is a major source, is located at a major source, or is 
part of a major source of emissions of hazardous air pollutants (HAP), 
except as provided in paragraph (d) of this section. A major source of 
HAP emissions is any stationary source or group of stationary sources 
located within a contiguous area and under common control that emits or 
has the potential to emit any single HAP at a rate of 9.07 megagrams 
(Mg) (10 tons) or more per year or any combination of HAP at a rate of 
22.68 Mg (25 tons) or more per year. You are not subject to this subpart 
if your large appliance surface coating facility is located at, or is 
part of, an area source of HAP emissions. An area source of HAP 
emissions is any stationary source or group of stationary sources 
located within a contiguous area and under common control that is not a 
major source.
    (b) The large appliance surface coating source category includes any 
facility engaged in the surface coating of a large appliance part or 
product. Large appliance parts and products include but are not limited 
to cooking equipment; refrigerators, freezers, and refrigerated cabinets 
and cases; laundry equipment; dishwashers, trash compactors, and water 
heaters; and heating, ventilation, and air-conditioning (HVAC) units, 
air-conditioning (except motor vehicle) units, air-conditioning and 
heating combination units, comfort furnaces, and electric heat pumps. 
Specifically excluded are heat transfer coils and large commercial and 
industrial chillers.
    (c) The large appliance surface coating activities and equipment to 
which this subpart applies are listed in paragraphs (c)(1) through (9) 
of this section:
    (1) Surface preparation of large appliance parts and products;
    (2) Preparation of a coating for application (e.g., mixing in 
thinners and other components);
    (3) Application of a coating to large appliance parts and products 
using, for example, spray guns or dip tanks;
    (4) Application of porcelain enamel, powder coating, and asphalt 
interior soundproofing coating;
    (5) Flash-off, drying, or curing following the coating application 
operation;
    (6) Cleaning of equipment used in coating operations (e.g., 
application equipment, hangers, racks);
    (7) Storage of coatings, thinners, and cleaning materials;
    (8) Conveying of coatings, thinners, and cleaning materials from 
storage areas to mixing areas or coating application areas, either 
manually (e.g., in buckets) or by automated means (e.g., transfer 
through pipes using pumps); and
    (9) Handling and conveying of waste materials generated by coating 
operations.
    (d) This subpart does not apply to surface coating that meets any of 
the criteria of paragraphs (d)(1) through (5) of this section.
    (1) The surface coating of large appliance parts such as metal or 
plastic handles, hinges, or fasteners that have a wider use beyond large 
appliances is not subject to this subpart.
    (2) The surface coating of large appliances conducted for the 
purpose of repairing or maintaining large appliances used by a facility 
and not for commerce is not subject to this subpart unless organic HAP 
emissions from the surface coating itself are as high as the rates 
specified in paragraph (a) of this section.
    (3) The surface coating of heat transfer coils or large commercial 
and industrial chillers.
    (4) The provisions of this subpart do not apply to research or 
laboratory facilities; janitorial, building, and facility maintenance 
operations; hobby shops operated for noncommercial purposes or coating 
applications using hand-held non-refillable aerosol containers.
    (5) The provisions of this subpart do not apply to processes 
involving metal plating or phosphating of a substrate.
    (e) If you own or operate an affected source that is subject to this 
subpart and at the same affected source you also perform surface coating 
subject to any other subparts in this part, you may choose for the 
affected source to comply with only one subpart. In order to choose this 
alternative, the total mass of organic HAP emissions from all surface 
coating operations in the affected source must be less than or equal to 
the total mass of organic HAP

[[Page 614]]

emissions that would result if it complied separately with all 
applicable subparts. You must make this comparison for the initial 
compliance period and report it in the Notification of Compliance Status 
as required in Sec. 63.4110(b)(10) and in the Notification of 
Compliance Status required by the other subparts. If you choose this 
alternative, your demonstration of compliance with the other subpart 
constitutes compliance with this subpart.



Sec. 63.4082  What parts of my plant does this subpart cover?

    (a) This subpart applies to each new, reconstructed, and existing 
affected source.
    (b) The affected source is the collection of all of the items listed 
in paragraphs (b)(1) through (4) of this section that are part of the 
large appliance surface coating facility:
    (1) All coating operations as defined in Sec. 63.4181;
    (2) All storage containers and mixing vessels in which coatings, 
thinners, and cleaning materials are stored or mixed;
    (3) All manual and automated equipment and containers used for 
conveying coatings, thinners, and cleaning materials; and
    (4) All storage containers and all manual and automated equipment 
and containers used for conveying waste materials generated by a coating 
operation.
    (c) An affected source is a new affected source if you commenced its 
construction after July 23, 2002, and the construction is of a 
completely new large appliance surface coating facility where previously 
no large appliance surface coating facility had existed.
    (d) An affected source is reconstructed if you meet the criteria as 
defined in Sec. 63.2.
    (e) An affected source is existing if it is not new or 
reconstructed.



Sec. 63.4083  When do I have to comply with this subpart?

    The date by which you must comply with this subpart is called the 
compliance date. The compliance date for each type of affected source is 
specified in paragraphs (a) through (c) of this section. The compliance 
date begins the initial compliance period during which you conduct the 
initial compliance demonstration described in Sec. Sec. 63.4140, 
63.4150, and 63.4160.
    (a) For a new or reconstructed affected source, the compliance date 
is the applicable date in paragraph (a)(1) or (2) of this section.
    (1) If the initial startup of your new or reconstructed affected 
source is before July 23, 2002, the compliance date is July 23, 2002.
    (2) If the initial startup of your new or reconstructed affected 
source occurs after July 23, 2002, the compliance date is the date of 
initial startup of your affected source.
    (b) For an existing affected source, the compliance date is July 25, 
2005.
    (c) For an area source that increases its emissions or its potential 
to emit such that it becomes a major source of HAP emissions, the 
compliance date is specified in paragraphs (c)(1) and (2) of this 
section.
    (1) For any portion of the source that becomes a new or 
reconstructed affected source subject to this subpart, the compliance 
date is the date of initial startup of the affected source, or the date 
the area source becomes a major source, or July 23, 2002, whichever is 
latest.
    (2) For any portion of the source that becomes an existing affected 
source subject to this subpart, the compliance date is the date 1 year 
after the area source becomes a major source or July 25, 2005, whichever 
is later.
    (d) You must meet the notification requirements in Sec. 63.4110 
according to the dates specified in that section and in subpart A of 
this part. Some of the notifications must be submitted before the 
compliance dates described in paragraphs (a) through (c) of this 
section.

                          Emission Limitations



Sec. 63.4090  What emission limits must I meet?

    (a) For an existing affected source, you must limit organic HAP 
emissions to the atmosphere to no more than 0.13 kilogram per liter (kg/
liter) (1.1 pound per gallon (lb/gal)) of coating solids used during 
each compliance period.
    (b) For a new or reconstructed affected source, you must limit 
organic HAP emissions to the atmosphere to no

[[Page 615]]

more than 0.022 kg/liter (0.18 lb/gal) of coating solids used during 
each compliance period.



Sec. 63.4091  What are my options for meeting the emission limits?

    You must include all coatings, thinners, and cleaning materials used 
in the affected source when determining whether the organic HAP emission 
rate is equal to or less than the applicable emission limit in Sec. 
63.4090. To make this determination, you must use at least one of the 
three compliance options listed in paragraphs (a) through (c) of this 
section. You may apply any of the compliance options to an individual 
coating operation or to multiple coating operations as a group or to the 
entire affected source. You may use different compliance options for 
different coating operations or at different times on the same coating 
operation. However, you may not use different compliance options at the 
same time on the same coating operation. If you switch between 
compliance options for any coating operation or group of coating 
operations, you must document this switch as required by Sec. 
63.4130(c), and you must report it in the next semiannual compliance 
report required in Sec. 63.4120.
    (a) Compliant material option. Demonstrate that the organic HAP 
content of each coating used in the coating operation(s) is less than or 
equal to the applicable emission limit in Sec. 63.4090, and that each 
thinner and each cleaning material used contains no organic HAP. You 
must meet all the requirements of Sec. Sec. 63.4140, 63.4141, and 
63.4142 to demonstrate compliance with the emission limit using this 
option.
    (b) Emission rate without add-on controls option. Demonstrate that, 
based on data on the coatings, thinners, and cleaning materials used in 
the coating operation(s), the organic HAP emission rate for the coating 
operation(s) is less than or equal to the applicable emission limit in 
Sec. 63.4090. You must meet all the requirements of Sec. Sec. 63.4150, 
63.4151, and 63.4152 to demonstrate compliance with the emission limit 
using this option.
    (c) Emission rate with add-on controls option. Demonstrate that, 
based on data on the coatings, thinners, and cleaning materials used in 
the coating operation(s) and the emission reductions achieved by 
emission capture and add-on controls, the organic HAP emission rate for 
the coating operation(s) is less than or equal to the applicable 
emission limit in Sec. 63.4090. If you use this compliance option, you 
must also demonstrate that all emission capture systems and add-on 
control devices for the coating operation(s) meet the operating limits 
required in Sec. 63.4092, except for solvent recovery systems for which 
you conduct liquid-liquid material balances according to Sec. 
63.4161(h), and that you meet the work practice standards required in 
Sec. 63.4093. You must meet all the requirements of Sec. Sec. 63.4160 
through 63.4168 to demonstrate compliance with the emission limits, 
operating limits, and work practice standards using this option.



Sec. 63.4092  What operating limits must I meet?

    (a) For any coating operation(s) on which you use the compliant 
material option or the emission rate without add-on controls option, you 
are not required to meet any operating limits.
    (b) For any controlled coating operation(s) on which you use the 
emission rate with add-on controls option, except those for which you 
use a solvent recovery system and conduct a liquid-liquid material 
balance according to Sec. 63.4161(h), you must meet the operating 
limits specified in Table 1 to this subpart. These operating limits 
apply to the emission capture and control systems on the coating 
operation(s) for which you use this option, and you must establish the 
operating limits during the performance test according to the 
requirements in Sec. 63.4167. You must meet the operating limits at all 
times after you establish them.
    (c) If you use an add-on control device other than those listed in 
Table 1 to this subpart or wish to monitor an alternative parameter and 
comply with a different operating limit, you must apply to the U.S. 
Environmental Protection Agency (EPA) Administrator for approval of 
alternative monitoring under Sec. 63.8(f).

[[Page 616]]



Sec. 63.4093  What work practice standards must I meet?

    (a) For any coating operation(s) on which you use the compliant 
material option or the emission rate without add-on controls option, you 
are not required to meet any work practice standards.
    (b) If you use the emission rate with add-on controls option, you 
must develop and implement a work practice plan to minimize organic HAP 
emissions from the storage, mixing, and conveying of coatings, thinners, 
and cleaning materials used in, and waste materials generated by, the 
coating operation(s) for which you use this option; or you must meet an 
alternative standard as provided in paragraph (c) of this section. The 
plan must specify practices and procedures to ensure that, at a minimum, 
the elements specified in paragraphs (b)(1) through (5) of this section 
are implemented.
    (1) All organic-HAP-containing coatings, thinners, cleaning 
materials, and waste materials must be stored in closed containers.
    (2) Spills of organic-HAP-containing coatings, thinners, cleaning 
materials, and waste materials must be minimized.
    (3) Organic-HAP-containing coatings, thinners, cleaning materials, 
and waste materials must be conveyed from one location to another in 
closed containers or pipes.
    (4) Mixing vessels which contain organic-HAP-containing coatings and 
other materials must be closed except when adding to, removing, or 
mixing the contents.
    (5) Emissions of organic HAP must be minimized during cleaning of 
storage, mixing, and conveying equipment.
    (c) As provided in Sec. 63.6(g), we, the EPA, may choose to grant

material option or the emission rate without add-on controls option, as 
specified in Sec. 63.4091(a) and (b), must be in compliance with the 
applicable emission limit in Sec. 63.4090 at all times.
    (2) Any coating operation(s) for which you use the emission rate 
with add-on controls option, as specified in Sec. 63.4091(c), must be 
in compliance with the applicable emission limit in Sec. 63.4090 and 
work practice standards in Sec. 63.4093 at all times. Each controlled 
coating operation must be in compliance with the operating limits for 
emission capture systems and add-on control devices required by Sec. 
63.4092 at all times, except for solvent recovery systems for which you 
conduct liquid-liquid material balances according to Sec. 63.4161(h).
    (b) You must always operate and maintain your affected source, 
including all air pollution control and monitoring equipment you use for 
purposes of complying with this subpart, according to the provisions in 
Sec. 63.6(e)(1)(i).
    (c) If your affected source uses an emission capture system and add-
on control device, you must maintain a log detailing the operation and 
maintenance of the emission capture system, add-on control device, and 
continuous parameter monitors during the period between the compliance 
date specified for your affected source in Sec. 63.4083 and the date 
when the initial emission capture system and add-on control device 
performance tests have been completed as specified in Sec. 63.4160. 
This requirement does not apply to a solvent recovery system for which 
you conduct a liquid-liquid material balance according to Sec. 
63.4161(h) in lieu of conducting performance tests.
    (d) If your affected source uses an emission capture system and add-
on control device, you must develop a written startup, shutdown, and 
malfunction plan according to the provisions in Sec. 63.6(e)(3). The 
plan must address the startup, shutdown, and corrective actions in the 
event of a malfunction of the emission capture system or the add-on 
control device. The plan must also address any coating operation 
equipment that may cause increased emissions or that would affect

        Compliance Requirements for the Compliant Material Option



Sec. 63.4140  By what date must I conduct the initial compliance
demonstration?

    You must complete the initial compliance demonstration for the 
initial compliance period according to the requirements in Sec. 
63.4141. The initial compliance period begins on the applicable 
compliance date specified in Sec. 63.4083 and ends on the last day of 
the first full month after the compliance date. If the compliance date 
occurs on any day other than the first day of a month, then the initial 
compliance period extends through the end of that

[[Page 624]]

month plus the next month. The initial compliance demonstration includes 
the determination according to Sec. 63.4141 and supporting 
documentation showing that, during the initial compliance period, you 
used no coating with an organic HAP content that exceeded the applicable 
emission limit in Sec. 63.4090, and that you used no thinners or 
cleaning materials that contained organic HAP.



Sec. 63.4141  How do I demonstrate initial compliance with the 
emission limitations?

    You may use the compliant material option for any individual coating 
operation, for any group of coating operations in the affected source, 
or for all the coating operations in the affected source. You must use 
either the emission rate without add-on controls option or the emission 
rate with add-on controls option for any coating operation(s) in the 
affected source for which you do not use this option. To demonstrate 
initial compliance using the compliant material option, the coating 
operation or group of coating operations must use no coating with an 
organic HAP content that exceeds the applicable emission limit in Sec. 
63.4090 and must use no thinner or cleaning material that contains 
organic HAP, as determined according to this section during the initial 
compliance period. Any coating operation(s) for which you use the 
compliant material option is not required to meet the operating limits 
or work practice standards required in Sec. Sec. 63.4092 and 63.4093, 
respectively. To demonstrate initial compliance with the emission 
limitations using the compliant material option, you must meet all the 
requirements of this section for the coating operation(s) using this 
option. Use the procedures in this section on each coating, thinner, and 
cleaning material in the condition it is in when it is received from its 
manufacturer or supplier and prior to any alteration. You do not need to 
redetermine the HAP content of coatings, thinners, or cleaning materials 
that have been reclaimed onsite and reused in the coating operation(s) 
for which you use the compliant material option, provided these 
materials in their condition as received were demonstrated to comply 
with the compliant material option. If the mass fraction of organic HAP 
of a coating equals zero, determined according to paragraph (a) of this 
section, and you use the compliant material option, you are not required 
to comply with paragraphs (b) and (c) of this section for that coating.
    (a) Determine the mass fraction of organic HAP for each material 
used. You must determine the mass fraction of organic HAP for each 
coating, thinner, and cleaning material used during the compliance 
period by using one of the options in paragraphs (a)(1) through (5) of 
this section.
    (1) Method 311 (appendix A to 40 CFR part 63). You may use Method 
311 for determining the mass fraction of organic HAP. Use the procedures 
specified in paragraphs (a)(1)(i) and (ii) of this section when 
performing a Method 311 test.
    (i) Count each organic HAP that is measured to be present at 0.1 
percent by mass or more for Occupational Safety and Health 
Administration (OSHA)-defined carcinogens as specified in 29 CFR 
1910.1200(d)(4) and at 1.0 percent by mass or more for other organic HAP 
compounds. For example, if toluene (not an OSHA carcinogen) is measured 
to be 0.5 percent of the material by mass, you do not have to count it. 
Express the mass fraction of each organic HAP you count as a value 
truncated to four places after the decimal point (for example, 0.3791).
    (ii) Calculate the total mass fraction of organic HAP in the test 
material by adding up the individual organic HAP mass fractions and 
truncating the result to three places after the decimal point (for 
example, 0.763).
    (2) Method 24 (appendix A to 40 CFR part 60). For coatings, you may 
use Method 24 to determine the mass fraction of nonaqueous volatile 
matter and use that value as a substitute for mass fraction of organic 
HAP.
    (3) Alternative method. You may use an alternative test method for 
determining the mass fraction of organic HAP once the Administrator has 
approved it. You must follow the procedure in Sec. 63.7(f) to submit an 
alternative test method for approval.
    (4) Information from the supplier or manufacturer of the material. 
You may

[[Page 625]]

rely on information other than that generated by the test methods 
specified in paragraphs (a)(1) through (3) of this section, such as 
manufacturer's formulation data if they represent each organic HAP that 
is present at 0.1 percent by mass or more for OSHA-defined carcinogens 
as specified in 29 CFR 1910.1200(d)(4) and at 1.0 percent by mass or 
more for other organic HAP compounds. For example, if toluene (not an 
OSHA carcinogen) is 0.5 percent of the material by mass, you do not have 
to count it. If there is a disagreement between such information and 
results of a test conducted according to paragraphs (a)(1) through (3) 
of this section, then the test method results will take precedence.
    (5) Solvent blends. Solvent blends may be listed as single 
components for some materials in data provided by manufacturers or 
suppliers. Solvent blends may contain organic HAP which must be counted 
toward the total organic HAP mass fraction of the materials. When test 
data and manufacturer's data for solvent blends are not available, you 
may use the default values for mass fraction of organic HAP in these 
solvent blends listed in Table 3 or 4 of this subpart. If you use the 
tables, you must use the values in Table 3 for all solvent blends that 
match Table 3 entries, and you may only use Table 4 if the solvent 
blends in the materials you use do not match any of the solvent blends 
in Table 3, and you only know whether the blend is aliphatic or 
aromatic. However, if the results of a Method 311 test indicate higher 
values than those listed on Table 3 or 4 of this subpart, the Method 311 
results will take precedence.
    (b) Determine the volume fraction of coating solids for each 
coating. You must determine the volume fraction of coating solids 
(liters of coating solids per liter of coating) for each coating used 
during the compliance period by a test, by information provided by the 
supplier or the manufacturer of the material, or by calculation as 
specified in paragraphs (b)(1) through (3) of this section.
    (1) ASTM Method D2697-86 (Reapproved 1998) or D6093-97. You may use 
ASTM Method D2697-86 (Reapproved 1998), ``Standard Test Method for 
Volume Nonvolatile Matter in Clear or Pigmented Coatings,'' or D6093-97, 
``Standard Test Method for Percent Volume Nonvolatile Matter in Clear or 
Pigmented Coatings Using a Helium Gas Pycnometer'' (incorporated by 
reference, see Sec. 63.14) to determine the volume fraction of coating 
solids for each coating. Divide the nonvolatile volume percent obtained 
with the methods by 100 to calculate volume fraction of coating solids.
    (2) Information from the supplier or manufacturer of the material. 
You may obtain the volume fraction of coating solids for each coating 
from the supplier or manufacturer.
    (3) Calculation of volume fraction of coating solids. If the volume 
fraction of coating solids cannot be determined using the options in 
paragraphs (b)(1) and (2) of this section, you must determine it using 
Equation 1 of this section:
[GRAPHIC] [TIFF OMITTED] TR23JY02.018

Where:

Vs = volume fraction of coating solids, liters coating solids 
          per liter coating.
mvolatiles = total volatile matter content of the coating, 
          including HAP, volatile organic compounds (VOC), water, and 
          exempt compounds, determined according to Method 24 in 
          appendix A of 40 CFR part 60, grams volatile matter per liter 
          coating.
Davg = average density of volatile matter in the coating, 
          grams volatile matter per liter volatile matter, determined 
          from test results using ASTM Method D1475-98, ``Standard Test 
          Method for Density of Liquid Coatings, Inks, and Related 
          Products'' (incorporated by reference, see Sec. 63.14) 
          information from the supplier or manufacturer of the material, 
          or reference sources providing density or specific gravity 
          data for pure materials. If there is disagreement between ASTM 
          Method D1475-98 test results and other information sources, 
          the test results will take precedence.

    (c) Determine the density of each coating. Determine the density of 
each coating used during the compliance period from test results using 
ASTM Method D1475-98, ``Standard Test Method for Density of Liquid 
Coatings, Inks, and Related Products'' (incorporated by reference, see 
Sec. 63.14), information

[[Page 626]]

from the supplier or manufacturer of the material, or reference sources 
providing density or specific gravity data for pure materials. If there 
is disagreement between ASTM Method D1475-98 test results and other 
information sources, the test results will take precedence.
    (d) Determine the organic HAP content of each coating. Determine the 
organic HAP content, kg organic HAP per liter coating solids, of each 
coating used during the compliance period, using Equation 2 of this 
section, except that if the mass fraction of organic HAP equals zero, 
then the organic HAP content also equals zero and you are not required 
to use Equation 2 to calculate the organic HAP content:
[GRAPHIC] [TIFF OMITTED] TR23JY02.019

Where:

Hc = organic HAP content of the coating, kg organic HAP per 
          liter coating solids.
Dc = density of coating, kg coating per liter coating, 
          determined according to paragraph (c) of this section.
Wc = mass fraction of organic HAP in the coating, kg organic 
          HAP per kg coating, determined according to paragraph (a) of 
          this section.
Vs = volume fraction of coating solids, liters coating solids 
          per liter coating, determined according to paragraph (b) of 
          this section.

    (e) The organic HAP content for each coating used during the initial 
compliance period must be less than or equal to the applicable emission 
limit in Sec. 63.4090; and each thinner and cleaning material used 
during the initial compliance period must contain no organic HAP, 
determined according to paragraph (a) of this section. You must keep all 
records required by Sec. Sec. 63.4130 and 63.4131. As part of the 
Notification of Compliance Status required in Sec. 63.4110, you must 
identify the coating operation(s) for which you used the compliant 
material option and submit a statement that the coating operation(s) was 
(were) in compliance with the emission limitations during the initial 
compliance period because you used no coatings for which the organic HAP 
content exceeds the applicable emission limit in Sec. 63.4090, and you 
used no thinners or cleaning materials that contain organic HAP, 
determined according to paragraph (a) of this section.



Sec. 63.4142  How do I demonstrate continuous compliance with the
emission limitations?

    (a) For each compliance period, to demonstrate continuous 
compliance, you must use no coating for which the organic HAP content, 
determined according to Sec. 63.4141(d), exceeds the applicable 
emission limit in Sec. 63.4090, and use no thinner or cleaning material 
that contains organic HAP, determined according to Sec. 63.4141(a). 
Each month following the initial compliance period described in Sec. 
63.4140 is a compliance period.
    (b) If you choose to comply with the emission limitations by using 
the compliant material option, the use of any coating, thinner, or 
cleaning material that does not meet the criteria specified in paragraph 
(a) of this section is a deviation from the emission limitations that 
must be reported as specified in Sec. Sec. 63.4110(b)(6) and 
63.4120(d).
    (c) As part of each semiannual compliance report required by Sec. 
63.4120, you must submit a statement that you were in compliance with 
the emission limitations during the reporting period because you used no 
thinners or cleaning materials that contained organic HAP, and you used 
no coatings for which the organic HAP content exceeded the applicable 
emission limit in Sec. 63.4090.
    (d) You must maintain records as specified in Sec. Sec. 63.4130 and 
63.4131.

 Compliance Requirements for the Emission Rate Without Add-On Controls 
                                 Option



Sec. 63.4150  By what date must I conduct the initial compliance
demonstration?

    You must complete the initial compliance demonstration for the 
initial compliance period according to the requirements of Sec. 
63.4151. The initial compliance period begins on the applicable 
compliance date specified in Sec. 63.4083 and ends on the last day of 
the first full month after the compliance date. If the compliance date 
occurs on any day other than the first day of a month, then the initial 
compliance period extends through the end of that

[[Page 627]]

month plus the next month. The initial compliance demonstration includes 
the calculations according to Sec. 63.4151 and supporting documentation 
showing that the organic HAP emission rate for the initial compliance 
period was equal to or less than the applicable emission limit in Sec. 
63.4090.



Sec. 63.4151  How do I demonstrate initial compliance with the 
emission limitations?

    You may use the emission rate without add-on controls option for any 
individual coating operation, for any group of coating operations in the 
affected source, or for all of the coating operations in the affected 
source. You must use either the compliant material option or the 
emission rate with add-on controls option for any coating operation(s) 
in the affected source for which you do not use this option. To 
demonstrate initial compliance using the emission rate without add-on 
controls option, the coating operation(s) must meet the applicable 
emission limit in Sec. 63.4090 but not the operating limits or work 
practice standards in Sec. Sec. 63.4092 and 63.4093, respectively, 
during the initial compliance period. You must meet all of the 
requirements of this section to demonstrate initial compliance with the 
applicable emission limit in Sec. 63.4090 for the coating operation(s). 
When calculating the organic HAP emission rate according to this 
section, do not include any coatings, thinners, or cleaning materials 
used on coating operations for which you use the compliant material 
option or the emission rate with add-on controls option. You do not need 
to redetermine the mass of organic HAP in coatings, thinners, or 
cleaning materials that have been reclaimed onsite and reused in the 
coating operation(s) for which you use the emission rate without add-on 
controls option.
    (a) Determine the mass fraction of organic HAP for each material. 
Determine the mass fraction of organic HAP for each coating, thinner, 
and cleaning material used during the compliance period according to the 
requirements in Sec. 63.4141(a).
    (b) Determine the volume fraction of coating solids for each 
coating. Determine the volume fraction of coating solids for each 
coating used during the compliance period according to the requirements 
in Sec. 63.4141(b).
    (c) Determine the density of each material. Determine the density of 
each coating, thinner, and cleaning material used during the compliance 
period according to the requirements in Sec. 63.4141(c).
    (d) Determine the volume of each material used during the compliance 
period. Determine the volume (liters) of each coating, thinner, and 
cleaning material used during the compliance period by measurement or 
usage records.
    (e) Calculate the mass of organic HAP emissions during the 
compliance period. The mass of organic HAP emissions is the combined 
mass of organic HAP contained in all coatings, thinners, and cleaning 
materials used during the compliance period minus the organic HAP in 
certain waste materials. Calculate it using Equation 1 of this section.
[GRAPHIC] [TIFF OMITTED] TR23JY02.000

          designated for shipment to a hazardous waste TSDF for 
          treatment or disposal during the compliance period, kg, 
          determined according to paragraph (e)(4) of this section. (You 
          may assign a value of zero to Rw if you do not wish 
          to use this allowance.)

sent to a TSDF. If you choose to account for the mass of organic HAP 
contained in waste materials sent or designated for shipment to a 
hazardous waste TSDF in the calculation of the mass of organic HAP 
emissions (Equation 1 of this section), then you must determine it 
according to paragraphs (e)(4)(i) through (v) of this section.
    (i) You may include in the determination of organic HAP in waste 
materials only the waste materials that are generated by coating 
operations for which you use Equation 1 of this section and that will be 
treated or disposed of by a facility that is regulated as a TSDF under 
40 CFR part 262, 264, 265, or 266. The TSDF may be either off-site or 
on-site. You may not include in the determination the organic HAP 
contained in wastewater.
    (ii) You must determine either the amount of waste materials sent to 
a TSDF during the compliance period or the amount collected and stored 
during the compliance period and designated for future transport to a 
TSDF. Do not include in your determination any waste materials sent to a 
TSDF during a compliance period if you have already included them in the 
amount collected and stored during that compliance period or a previous 
compliance period.
    (iii) Determine the total mass of organic HAP contained in the waste 
materials specified in paragraph (e)(4)(ii) of this section.
    (iv) You must document your methodology to determine the amount of

63.4090. You must keep all records as required by Sec. Sec. 63.4130 and 
63.4131. As part of the Notification of Compliance Status required by 
Sec. 63.4110, you must identify the coating operation(s) for which you 
used the emission rate without add-on controls option and submit a 
statement that the coating operation(s) was (were) in compliance with 
the emission limitations during the initial compliance period because 
the organic HAP emission rate was less than or equal to the applicable 
emission limit in Sec. 63.4090.



Sec. 63.4152  How do I demonstrate continuous compliance with the
emission limitations?

    (a) To demonstrate continuous compliance, the organic HAP emission 
rate for each compliance period, determined according to Sec. 
63.4151(a) through (g), must be less than or equal to the applicable 
emission limit in Sec. 63.4090. Each month following the initial 
compliance period described in Sec. 63.4150 is a compliance period.
    (b) If the organic HAP emission rate for any compliance period

deviation from the emission limitations for that compliance period and 
must be reported as specified in Sec. Sec. 63.4110(b)(6) and 
63.4120(e).
    (c) As part of each semiannual compliance report required by Sec.

specified in Sec. 63.4083 and ends on the last day of the first full 
month after the compliance date. If the compliance date occurs on any

[[Page 630]]

day other than the first day of a month, then the initial compliance 
period extends through the end of that month plus the next month. The 
initial compliance demonstration includes the results of emission 
capture system and add-on control device performance tests conducted 
according to Sec. Sec. 63.4164, 63.4165, and 63.4166; results of 
liquid-liquid material balances conducted according to Sec. 63.4161(h);

    (b) New and reconstructed affected sources. For a new or 
reconstructed affected source, you must meet the requirements of 
paragraphs (b)(1) through (4) this section.
    (1) All emission capture systems, add-on control devices, and CPMS 
you use to demonstrate compliance must be installed and operating no 
later than the applicable compliance date specified in Sec. 63.4183. 
Except for solvent recovery systems for which you conduct liquid-liquid 
material balances according to Sec. 63.4161(h), you must conduct a 
performance test of each capture system and add-on control device 
according to the procedures in Sec. Sec. 63.4164, 63.4165, and 63.4166, 
and establish the operating limits required by Sec. 63.4092 no later

emission capture system and add-on control device required by Sec. 
63.4092 until after you have completed the performance tests specified 
in paragraph (b)(1) of this section. Instead, you must maintain a log 
detailing the operation and maintenance of the emission capture system, 
add-on control device, and continuous parameter monitors during the 
period between the compliance date and the performance test. You must 
begin complying with the operating limits for your affected source on 
the date you complete the performance tests specified in paragraph 
(b)(1) of this section. This requirement does not apply to solvent 
recovery systems for which you conduct liquid-liquid material balances 
according to Sec. 63.4161(h).



Sec. 63.4161  How do I demonstrate initial compliance?

    You may use the emission rate with add-on controls option for any 
coating operation, for any group of coating operations in the affected 
source, or for all of the coating operations in the affected source. You 
may include both

[[Page 631]]

controlled and uncontrolled coating operations in a group for which you 
use this option. You must use either the compliant material option or 
the emission rate without add-on controls option for any coating 
operation(s) in the affected source for which you do not use this 
option. To demonstrate initial compliance, the coating operation(s) for 
which you use the emission rate with add-on controls option must meet 
the applicable emission limit in Sec. 63.4090 and the work practice 
standards required in Sec. 63.4093; and each controlled coating 
operation must meet the operating limits required in Sec. 63.4092. You 
must meet all the requirements of this section to demonstrate initial 
compliance with the emission limitations. When calculating the organic 
HAP emission rate according to this section, do not include any 
coatings, thinners, or cleaning materials used on coating operations for 
which you use the compliant material option or the emission rate without 
add-on controls option. You do not need to redetermine the mass of 
organic HAP in coatings, thinners, or cleaning materials that have been 
reclaimed onsite and reused in the coating operation(s) for which you 
use the emission rate with add-on controls option.
    (a) Except as provided in Sec. 63.4160(b)(4) and except for solvent 
recovery systems for which you conduct liquid-liquid material balances 
according to the requirements of Sec. 63.4161(h), you must establish 
and demonstrate continuous compliance during the initial compliance 
period with the operating limits required by Sec. 63.4092, using the 
procedures specified in Sec. Sec. 63.4167 and 63.4168.
    (b) You must develop, implement, and document your implementation of 
the work practice plan required by Sec. 63.4093 during the initial 
compliance period as specified in Sec. 63.4130.
    (c) You must follow the procedures in paragraphs (d) through (l) of 
this section to demonstrate compliance with the applicable emission 
limit in Sec. 63.4090.
    (d) Determine the mass fraction of organic HAP, density, volume 
used, and volume fraction of coating solids. Follow the procedures 
specified in Sec. 63.4151(a) through (d) to determine the mass fraction 
of organic HAP, density, and volume of each coating, thinner, and 
cleaning material used during the compliance period, and the volume 
fraction of coating solids for each coating used during the compliance 
period.
    (e) Calculate the total mass of organic HAP emissions before add-on 
controls. Using Equation 1 of Sec. 63.4151, calculate the total mass of 
organic HAP emissions before add-on controls from all coatings, 
thinners, and cleaning materials used during the compliance period in 
the coating operation or group of coating operations for which you use 
the emission rate with add-on controls option.
    (f) Calculate the organic HAP emission reduction for each controlled 
coating operation. Determine the mass of organic HAP emissions reduced 
for each controlled coating operation during the compliance period. The 
emissions reduction determination quantifies the total organic HAP 
emissions that pass through the emission capture system and are 
destroyed or removed by the add-on control device. Use the procedures in 
paragraph (g) of this section to calculate the mass of organic HAP 
emissions reduction for each controlled coating operation using an 
emission capture system and add-on control device other than a solvent 
recovery system for which you conduct liquid-liquid material balances. 
For each controlled coating operation using a solvent recovery system 
for which you conduct a liquid-liquid material balance, use the 
procedures in paragraph (h) of this section to calculate the organic HAP 
emissions reduction.
    (g) Calculate the organic HAP emissions reduction for controlled 
coating operations not using liquid-liquid material balance. For each 
controlled coating operation using an emission capture system and add-on 
control device other than a solvent recovery system for which you 
conduct liquid-liquid material balances, calculate organic HAP emissions 
reduction, using Equation 1 of this section, by applying the emission 
capture system efficiency and add-on control device efficiency to the 
mass of organic HAP contained in the

[[Page 632]]

coatings, thinners, and cleaning materials that are used in the coating 
operation served by the emission capture system and add-on control 
device during the compliance period. For any period of time a deviation 
specified in Sec. 63.4163(c) or (d) occurs in the controlled coating 
operation, including a deviation during a period of startup, shutdown, 
or malfunction, you must assume zero efficiency for the emission capture 
system and add-on control device. For the purposes of completing the 
compliance calculations, you must treat the materials used during a 
deviation on a controlled coating operation as if they were used on an 
uncontrolled coating operation for the time period of the deviation. You 
must not include those materials in the calculations of organic HAP 
emissions reduction in Equation 1 of this section.

Notification of Compliance Status required by Sec. 63.4110, you must 
identify the coating operation(s) for which you used the

[[Page 635]]

emission rate with add-on controls option and submit a statement that 
the coating operation(s) was (were) in compliance with the emission 
limitations during the initial compliance period because the organic HAP 
emission rate was less than or equal to the applicable emission limit in 
Sec. 63.4090, and you achieved the operating limits required by Sec. 
63.4092 and the work practice standards required by Sec. 63.4093.



Sec. 63.4162  [Reserved]



Sec. 63.4163  How do I demonstrate continuous compliance with the
emission limitations?

    (a) To demonstrate continuous compliance with the applicable 
emission limit in Sec. 63.4090, the organic HAP emission rate for each 
compliance period determined according to the procedures in Sec. 
63.4161 must be equal to or less than the applicable emission limit in 
Sec. 63.4090. Each month following the initial compliance period 
described in Sec. 63.4160 is a compliance period.
    (b) If the organic HAP emission rate for any compliance period 
exceeded the applicable emission limit in Sec. 63.4090, this is a 
deviation from the emission limitation for that compliance period and 
must be reported as specified in Sec. Sec. 63.4110(b)(6) and 
63.4120(g).
    (c) You must demonstrate continuous compliance with each operating 
limit required by Sec. 63.4092 that applies to you as specified in 
Table 1 to this subpart.
    (1) If an operating parameter is out of the allowed range specified 
in Table 1 to this subpart, this is a deviation from the operating limit 
that must be reported as specified in Sec. Sec. 63.4110(b)(6) and 
63.4120(g).
    (2) If an operating parameter deviates from the operating limit 
specified in Table 1 to this subpart, then you must assume that the 
emission capture system and add-on control device were achieving zero 
efficiency during the time period of the deviation. For the purposes of 
completing the compliance calculations specified in Sec. 63.4161, you 
must treat the materials used during a deviation on a controlled coating 
operation as if they were used on an uncontrolled coating operation for 
the time period of the deviation. You must not include those materials 
in the calculation of organic HAP emissions reductions in Equation 1 of 
Sec. 63.4161.
    (d) You must meet the requirements for bypass lines in Sec. 
63.4168(b). If any bypass line is opened and emissions are diverted to 
the atmosphere when the coating operation is running, this is a 
deviation that must be reported as specified in Sec. Sec. 63.4110(b)(6) 
and 63.4120(g). For the purposes of completing the compliance 
calculations specified in Sec. 63.4161, you must treat the materials 
used during a deviation on a controlled coating operation as if they 
were used on an uncontrolled coating operation for the time period of 
the deviation. You must not include those materials in the calculation 
of organic HAP emissions reductions in Equation 1 of Sec. 63.4161.
    (e) You must demonstrate continuous compliance with the work 
practice standards in Sec. 63.4093. If you did not develop a work 
practice plan, or you did not implement the plan, or you did not keep 
the records required by Sec. 63.4130(k)(9), this is a deviation from 
the work practice standards that must be reported as specified in 
Sec. Sec. 63.4110(b)(6) and 63.4120(g).
    (f) As part of each semiannual compliance report required in Sec. 
63.4120, you must submit a statement that you were in compliance with 
the emission limitations during the reporting period because the organic 
HAP emission rate for each compliance period was less than or equal to 
the applicable emission limit in Sec. 63.4090, and you achieved the 
operating limits required by Sec. 63.4092 and the work practice 
standards required by Sec. 63.4093 during each compliance period.
    (g) [Reseved]
    (h) Consistent with Sec. Sec. 63.6(e) and 63.7(e)(1), deviations 
that occur during a period of startup, shutdown, or malfunction of the 
emission capture system, add-on control device, or coating operation 
that may affect emission capture or control device efficiency are not 
violations if you demonstrate to the Administrator's satisfaction that 
you were operating in accordance with Sec. 63.6(e). The Administrator 
will determine whether deviations that occur during a period of startup, 
shutdown, or malfunction are violations according to the provisions in 
Sec. 63.6(e).

Sec. 63.4164  What are the general requirements for performance tests?

    (a) You must conduct each performance test required by Sec. 63.4160 
according to the requirements in Sec. 63.7(e)(1) and under the 
conditions in this section unless you obtain a waiver of the performance 
test according to the provisions in Sec. 63.7(h).
    (1) Representative coating operation operating conditions. You must 
conduct the performance test under representative operating conditions 
for the coating operation. Operations during periods of startup, 
shutdown, or malfunction and periods of nonoperation do not constitute 
representative conditions. You must record the process information that 
is necessary to document operating conditions during the test and 
explain why the conditions represent normal operation.
    (2) Representative emission capture system and add-on control device 
operating conditions. You must conduct the performance test when the 
emission capture system and add-on control device are operating at a 
representative flow rate, and the add-on control device is operating at 
a representative inlet concentration. You must record information that 
is necessary to document emission capture system and add-on control 
device operating conditions during the test and explain why the 
conditions represent normal operation.
    (b) You must conduct each performance test of an emission capture 
system according to the requirements in Sec. 63.4165 and of an add-on 
control device according to the requirements in Sec. 63.4166.
    (c) The performance test to determine add-on control device organic 
HAP destruction or removal efficiency must consist of three runs as 
specified in Sec. 63.7(e)(3) and each run must last at least 1 hour.



Sec. 63.4165  How do I determine the emission capture system efficiency?

    You must use the procedures and test methods in this section to 
determine capture efficiency as part of the performance test required by 
Sec. 63.4160.
    (a) You may assume the capture system efficiency is 100 percent if 
both of the conditions in paragraphs (a)(1) and (2) of this section are 
met:
    (1) The capture system meets the criteria in Method 204 of appendix 
M to 40 CFR part 51 for a PTE and directs all the exhaust gases from the 
enclosure to an add-on control device.
    (2) All coatings, thinners, and cleaning materials used in the 
coating operation are applied within the capture system; coating solvent 
flash-off and coating, curing, and drying occurs within the capture 
system and the removal or evaporation of cleaning materials from the 
surfaces they are applied to occurs within the capture system. For 
example, this criterion is not met if parts enter the open shop 
environment when being moved between a spray booth and a curing oven.
    (b) If the capture system does not meet both of the criteria in 
paragraphs (a)(1) and (2) of this section, then you must use one of the 
three protocols described in paragraphs (c), (d), and (e) of this 
section to measure capture efficiency. The capture efficiency 
measurements use TVH capture efficiency as a surrogate for organic HAP 
capture efficiency. For the protocols in paragraphs (c) and (d) of this 
section, the capture efficiency measurement must consist of three test 
runs. Each test run must be at least 3 hours duration or the length of a 
production run, whichever is longer, up to 8 hours. For the purposes of 
this test, a production run means the time required for a single part to 
go from the beginning to the end of production which includes surface 
preparation activities and drying or curing time.
    (c) Liquid-to-uncaptured-gas protocol using a temporary total 
enclosure or building enclosure. The liquid-to-uncaptured-gas protocol 
compares the mass of liquid TVH in materials used in the coating 
operation, to the mass of TVH emissions not captured by the emission 
capture system. Use a temporary total enclosure or a building enclosure 
and the procedures in paragraphs (c)(1) through (6) of this section

[[Page 637]]

to measure emission capture system efficiency using the liquid-to-
uncaptured-gas protocol.
    (1) Either use a building enclosure or construct an enclosure around 
the coating operation where coatings, thinners, and cleaning materials 
are applied, and all areas where emissions from these applied coatings 
and materials subsequently occur, such as flash-off, curing, and drying 
areas. The areas of the coating operation where capture devices collect 
emissions for routing to an add-on control device, such as the entrance 
and exit areas of an oven or spray booth, must also be inside the 
enclosure. The enclosure must meet the applicable definition of a 
temporary total enclosure or building enclosure in Method 204 of 
appendix M to 40 CFR part 51.
    (2) Use Method 204A or 204F of appendix M to 40 CFR part 51 to 
determine the mass fraction of TVH liquid input from each coating, 
thinner, and cleaning material used in the coating operation during each 
capture efficiency test run. To make the determination, substitute TVH 
for each occurrence of the term VOC in the methods.
    (3) Use Equation 1 of this section to calculate the total mass of 
TVH liquid input from all the coatings, thinners, and cleaning materials 
used in the coating operation during each capture efficiency test run.
[GRAPHIC] [TIFF OMITTED] TR23JY02.013

Where:

TVHused = total mass of TVH liquid input from all coatings, 
          thinners, and cleaning materials used in the coating operation 
          during the capture efficiency test run, kg.
TVHi = mass fraction of TVH in coating, thinner, or cleaning 
          material, i, that is used in the coating operation during the 
          capture efficiency test run, kg TVH per kg material.
Voli = total volume of coating, thinner, or cleaning 
          material, i, used in the coating operation during the capture 
          efficiency test run, liters.
Di = density of coating, thinner, or cleaning material, i, kg 
          material per liter material.
n = number of different coatings, thinners, and cleaning materials used 
          in the coating operation during the capture efficiency test 
          run.

    (4) Use Method 204D or E of appendix M to 40 CFR part 51 to measure 
the total mass, kg, of TVH emissions that are not captured by the 
emission capture system; they are measured as they exit the temporary 
total enclosure or building enclosure during each capture efficiency 
test run. To make the measurement substitute TVH for each occurrence of 
the term VOC in the methods.
    (i) Use Method 204D if the enclosure is a temporary total enclosure.
    (ii) Use Method 204E if the enclosure is a building enclosure. 
During the capture efficiency measurement, all organic compound emitting 
operations inside the building enclosure, other than the coating 
operation for which capture efficiency is being determined must be shut 
down, but all fans and blowers must be operating normally.
    (5) For each capture efficiency test run, determine the percent 
capture efficiency of the emission capture system, using Equation 2 of 
this section:
[GRAPHIC] [TIFF OMITTED] TR23JY02.014


[[Page 638]]


Where:

CE = capture efficiency of the emission capture system vented to the 
          add-on control device, percent.
TVHused = total mass of TVH liquid input used in the coating 
          operation during the capture efficiency test run, kg.
TVHuncaptured = total mass of TVH that is not captured by the 
          emission capture system and that exits from the temporary 
          total enclosure or building enclosure during the capture 
          efficiency test run, kg.

    (6) Determine the capture efficiency of the emission capture system 
as the average of the capture efficiencies measured in the three test 
runs.
    (d) Gas-to-gas protocol using a temporary total enclosure or a 
building enclosure. The gas-to-gas protocol compares the mass of TVH 
emissions captured by the emission capture system to the mass of TVH 
emissions not captured. Use a temporary total enclosure or a building 
enclosure and the procedures in paragraphs (d)(1) through (5) of this 
section to measure emission capture system efficiency using the gas-to-
gas protocol.
    (1) Either use a building enclosure or construct an enclosure around 
the coating operation where coatings, thinners, and cleaning materials 
are applied and all areas where emissions from these applied coatings 
and materials subsequently occur such as flash-off, curing, and drying 
areas. The areas of the coating operation where capture devices collect 
emissions generated by the coating operation for routing to an add-on 
control device, such as the entrance and exit areas of an oven or a 
spray booth, must also be inside the enclosure. The enclosure must meet 
the applicable definition of a temporary total enclosure or building 
enclosure in Method 204 of appendix M to 40 CFR part 51.
    (2) Use Method 204B or 204C of appendix M to 40 CFR part 51 to 
measure the total mass, kg, of TVH emissions captured by the emission 
capture system during each capture efficiency test run as measured at 
the inlet to the add-on control device. To make the measurement, 
substitute TVH for each occurrence of the term VOC in the methods.
    (i) The sampling points for the Method 204B or 204C measurement must 
be upstream from the add-on control device and must represent total 
emissions routed from the capture system and entering the add-on control 
device.
    (ii) If multiple emission streams from the capture system enter the 
add-on control device without a single common duct, then the emissions 
entering the add-on control device must be simultaneously measured in 
each duct, and the total emissions entering the add-on control device 
must be determined.
    (3) Use Method 204D or 204E of appendix M to 40 CFR part 51 to 
measure the total mass, kg, of TVH emissions that are not captured by 
the emission capture system; they are measured as they exit the 
temporary total enclosure or building enclosure during each capture 
efficiency test run. To make the measurement, substitute TVH for each 
occurrence of the term VOC in the methods.
    (i) Use Method 204D if the enclosure is a temporary total enclosure.
    (ii) Use Method 204E if the enclosure is a building enclosure. 
During the capture efficiency measurement, all organic compound emitting 
operations inside the building enclosure other than the coating 
operation for which capture efficiency is being determined must be shut 
down, but all fans and blowers must be operating normally.
    (4) For each capture efficiency test run, determine the percent 
capture efficiency of the emission capture system, using Equation 3 of 
this section:
[GRAPHIC] [TIFF OMITTED] TR23JY02.015

Where:

CE = capture efficiency of the emission capture system vented to the 
          add-on control device, percent.

[[Page 639]]

TVHcaptured = total mass of TVH captured by the emission 
          capture system as measured at the inlet to the add-on control 
          device during the emission capture efficiency test run, kg.
TVHuncaptured = total mass of TVH that is not captured by the 
          emission capture system and that exits from the temporary 
          total enclosure or building enclosure during the capture 
          efficiency test run, kg.

    (5) Determine the capture efficiency of the emission capture system 
as the average of the capture efficiencies measured in the three test 
runs.
    (e) Alternative capture efficiency protocol. As an alternative to 
the procedures specified in paragraphs (c) and (d) of this section, you 
may determine capture efficiency using any other capture efficiency 
protocol and test methods that satisfy the criteria of either the DQO or 
LCL approach as described in appendix A to subpart KK of this part.



Sec. 63.4166  How do I determine the add-on control device emission 
destruction or removal efficiency?

    (a) For all types of add-on control devices, use the test methods as 
specified in paragraphs (a)(1) through (5) of this section.
    (1) Use Method 1 or 1A of appendix A to 40 CFR part 60, as 
appropriate, to select sampling sites and velocity traverse points.
    (2) Use Method 2, 2A, 2C, 2D, 2F, or 2G of appendix A to 40 CFR part 
60, as appropriate, to measure gas volumetric flow rate.
    (3) Use Method 3, 3A, or 3B of appendix A to 40 CFR part 60, as 
appropriate, for gas analysis to determine dry molecular weight. You may 
also use as an alternative to Method 3B, the manual method for measuring 
the oxygen, carbon dioxide, and carbon monoxide content of exhaust gas 
in ANSI/ASME, PTC 19.10-1981, ``Flue and Exhaust Gas Analyses'' 
(incorporated by reference, see Sec. 63.14).
    (4) Use Method 4 of appendix A to 40 CFR part 60 to determine stack 
gas moisture.
    (5) Methods for determining gas volumetric flow rate, dry molecular 
weight, and stack gas moisture must be performed, as applicable, during 
each test run.
    (b) Measure total gaseous organic mass emissions as carbon at the 
inlet and outlet of the add-on control device simultaneously, using 
either Method 25 or 25A of appendix A to 40 CFR part 60, as specified in 
paragraphs (b)(1) through (3) of this section. You must use the same 
method for both the inlet and outlet measurements.
    (1) Use Method 25 if the add-on control device is an oxidizer and 
you expect the total gaseous organic concentration as carbon to be more 
than 50 parts per million (ppm) at the control device outlet.
    (2) Use Method 25A if the add-on control device is an oxidizer and 
you expect the total gaseous organic concentration as carbon to be 50 
ppm or less at the control device outlet.
    (3) Use Method 25A if the add-on control device is not an oxidizer.
    (c) If two or more add-on control devices are used for the same 
emission stream, then you must measure emissions at the outlet of each 
device. For example, if one add-on control device is a concentrator with 
an outlet for the high-volume, dilute stream that has been treated by 
the concentrator, and a second add-on control device is an oxidizer with 
an outlet for the low-volume, concentrated stream that is treated with 
the oxidizer, you must measure emissions at the outlet of the oxidizer 
and the high-volume dilute stream outlet of the concentrator.
    (d) For each test run, determine the total gaseous organic emissions 
mass flow rates for the inlet and the outlet of the add-on control 
device, using Equation 1 of this section. If there is more than one 
inlet or outlet to the add-on control device, you must calculate the 
total gaseous organic mass flow rate using Equation 1 of this section 
for each inlet and each outlet and then total all of the inlet emissions 
and total all of the outlet emissions.
[GRAPHIC] [TIFF OMITTED] TR23JY02.016

Where:

Mf = total gaseous organic emissions mass flow rate, kg/per 
          hour (h).
Cc = concentration of organic compounds as carbon in the vent 
          gas, as determined by Method 25 or Method 25A, parts per 
          million by volume (ppmv), dry basis.

[[Page 640]]

Qsd = volumetric flow rate of gases entering or exiting the 
          add-on control device, as determined by Method 2, 2A, 2C, 2D, 
          2F, or 2G, dry standard cubic meters/hour (dscm/h).
0.0416 = conversion factor for molar volume, kg-moles per cubic meter 
          (mol/m \3\) (@ 293 Kelvin (K) and 760 millimeters of mercury 
          (mm Hg)).

    (e) For each test run, determine the add-on control device organic 
emissions destruction or removal efficiency, using Equation 2 of this 
section.
[GRAPHIC] [TIFF OMITTED] TR23JY02.017

Where:

DRE = add-on control device organic emissions destruction or removal 
          efficiency, percent.
Mfi = total gaseous organic emissions mass flow rate at the 
          inlet(s) to the add-on control device, using Equation 1 of 
          this section, kg/h.
Mfo = total gaseous organic emissions mass flow rate at the 
          outlet(s) of the add-on control device, using Equation 1 of 
          this section, kg/h.

    (f) Determine the emission destruction or removal efficiency of the 
add-on control device as the average of the efficiencies determined in 
the three test runs and calculated in Equation 2 of this section.



Sec. 63.4167  How do I establish the emission capture system and 
add-on control device operating limits during the performance test?

    During the performance test required by Sec. 63.4160 and described 
in Sec. Sec. 63.4164, 63.4165, and 63.4166, you must establish the 
operating limits required by Sec. 63.4092 according to this section 
unless you have received approval for alternative monitoring and 
operating limits under Sec. 63.8(f) as specified in Sec. 63.4092.
    (a) Thermal oxidizers. If your add-on control device is a thermal 
oxidizer, establish the operating limits according to paragraphs (a)(1) 
and (2) of this section.
    (1) During the performance test, you must monitor and record the 
combustion temperature at least once every 15 minutes during each of the 
three test runs. You must monitor the temperature in the firebox of the 
thermal oxidizer or immediately downstream of the firebox before any 
substantial heat exchange occurs.
    (2) Use the data collected during the performance test to calculate 
and record the average combustion temperature maintained during the 
performance test. This average combustion temperature is the minimum 
operating limit for your thermal oxidizer.
    (b) Catalytic oxidizers. If your add-on control device is a 
catalytic oxidizer, establish the operating limits according to either 
paragraphs (b)(1) and (2) or paragraphs (b)(3) and (4) of this section.
    (1) During the performance test, you must monitor and record the 
temperature just before the catalyst bed and the temperature difference 
across the catalyst bed at least once every 15 minutes during each of 
the three test runs.
    (2) Use the data collected during the performance test to calculate 
and record the average temperature just before the catalyst bed and the 
average temperature difference across the catalyst bed maintained during 
the performance test. These are the minimum operating limits for your 
catalytic oxidizer.
    (3) As an alternative to monitoring the temperature difference 
across the catalyst bed, you may monitor the temperature just before the 
catalyst bed and implement a site-specific inspection and maintenance 
plan for your catalytic oxidizer as specified in paragraph (b)(4) of 
this section. During the performance test, you must monitor and record 
the temperature just before the catalyst bed at least once every 15 
minutes during each of the three test runs. Use the data collected 
during the performance test to calculate and record the average 
temperature just before the catalyst bed during the performance test. 
This is the minimum operating limit for your catalytic oxidizer.
    (4) You must develop and implement an inspection and maintenance 
plan for your catalytic oxidizer(s) for which you elect to monitor 
according to paragraph (b)(3) of this section. The plan must address, at 
a minimum, the elements specified in paragraphs (b)(4)(i) through (iii) 
of this section.

[[Page 641]]

    (i) Annual sampling and analysis of the catalyst activity (i.e., 
conversion efficiency) following the manufacturer's or catalyst 
supplier's recommended procedures.
    (ii) Monthly inspection of the oxidizer system including the burner 
assembly and fuel supply lines for problems and, as necessary, adjusting 
the equipment to assure proper air-to-fuel mixtures.
    (iii) Annual internal and monthly external visual inspection of the 
catalyst bed to check for channeling, abrasion, and settling. If 
problems are found, you must take corrective action consistent with the 
manufacturer's recommendations and conduct a new performance test to 
determine destruction efficiency according to Sec. 63.4166.
    (c) Carbon adsorbers. If your add-on control device is a carbon 
absorber, establish the operating limits according to paragraphs (c)(1) 
and (2) of this section.
    (1) You must monitor and record the total regeneration desorbing gas 
(e.g., steam or nitrogen) mass flow for each regeneration cycle and the 
carbon bed temperature after each carbon bed regeneration and cooling 
cycle for the regeneration cycle either immediately preceding or 
immediately following the performance test.
    (2) The operating limits for your carbon absorber are the minimum 
total desorbing gas mass flow recorded during the regeneration cycle and 
the maximum carbon bed temperature recorded after the cooling cycle.
    (d) Condensers. If your add-on control device is a condenser, 
establish the operating limits according to paragraphs (d)(1) and (2) of 
this section.
    (1) During the performance test, you must monitor and record the 
condenser outlet (product side) gas temperature at least once every 15 
minutes during each of the three test runs.
    (2) Use the data collected during the performance test to calculate 
and record the average condenser outlet (product side) gas temperature 
maintained during the performance test. This average condenser outlet 
gas temperature is the maximum operating limit for your condenser.
    (e) Concentrators. If your add-on control device includes a 
concentrator, you must establish operating limits for the concentrator 
according to paragraphs (e)(1) through (4) of this section.
    (1) During the performance test, you must monitor and record the 
desorption concentrate stream gas temperature at least once every 15 
minutes during each of the three runs of the performance test.
    (2) Use the data collected during the performance test to calculate 
and record the average temperature. This is the minimum operating limit 
for the desorption concentrate gas stream temperature.
    (3) During the performance test, you must monitor and record the 
pressure drop of the dilute stream across the concentrator at least once 
every 15 minutes during each of the three runs of the performance test.
    (4) Use the data collected during the performance test to calculate 
and record the average pressure drop. This is the maximum operating 
limit for the dilute stream across the concentrator.
    (f) Emission capture system. For each capture device that is not 
part of a PTE that meets the criteria of Sec. 63.4165(a), establish an 
operating limit for either the gas volumetric flow rate or duct static 
pressure as specified in paragraphs (f)(1) and (2) of this section. The 
operating limit for a PTE is specified in Table 1 to this subpart.
    (1) During the capture efficiency determination required by Sec. 
63.4160 and described in Sec. Sec. 63.4164 and 63.4165, you must 
monitor and record either the gas volumetric flow rate or the duct 
static pressure for each separate capture device in your emission 
capture system at least once every 15 minutes during each of the three 
test runs at a point in the duct between the capture device and the add-
on control device inlet.
    (2) Calculate and record the average gas volumetric flow rate or 
duct static pressure for the three test runs for each capture device. 
This average gas volumetric flow rate or duct static pressure is the 
minimum operating limit for that specific capture device.

[[Page 642]]



Sec. 63.4168  What are the requirements for continuous parameter
monitoring system installation, operation, and maintenance?

    (a) General. You must install, operate, and maintain each CPMS 
specified in paragraphs (c), (e), (f), and (g) of this section according 
to paragraphs (a)(1) through (6) of this section. You must install, 
operate, and maintain each CPMS specified in paragraphs (b) and (d) of 
this section according to paragraphs (a)(3) through (5) of this section.
    (1) The CPMS must complete a minimum of one cycle of operation for 
each successive 15-minute period. You must have a minimum of four 
equally spaced successive cycles of CPMS operation in 1 hour.
    (2) You must determine the average of all recorded readings for each 
successive 3-hour period of the emission capture system and add-on 
control device operation except as specified in paragraph (a)(6) of this 
section.
    (3) You must record the results of each inspection, calibration, and 
validation check of the CPMS.
    (4) You must maintain the CPMS at all times and have available 
necessary parts for routine repairs of the monitoring equipment.
    (5) You must operate the CPMS and collect emission capture system 
and add-on control device parameter data at all times that a controlled 
coating operation is operating except during monitoring malfunctions, 
associated repairs, and required quality assurance or control activities 
(including, if applicable, calibration checks and required zero and span 
adjustments).
    (6) You must not use emission capture system or add-on control 
device parameter data recorded during monitoring malfunctions, 
associated repairs, out-of-control periods, or required quality 
assurance or control activities when calculating data averages. You must 
use all the data collected during all other periods in calculating the 
data averages for determining compliance with the emission capture 
system and add-on control device operating limits.
    (7) A monitoring malfunction is any sudden, infrequent, not 
reasonably preventable failure of the CPMS to provide valid data. 
Monitoring failures that are caused in part by poor maintenance or 
careless operation are not malfunctions. Except for periods of required 
quality assurance or control activities, any period during which the 
CPMS fails to operate and record data continuously as required by 
paragraph (a)(1) of this section, or generates data that cannot be 
included in calculating averages as specified in paragraph (a)(6) of 
this section, is a deviation from the monitoring requirements.
    (b) Capture system bypass line. You must comply with the 
requirements of paragraphs (a)(3) through (5) and (b)(1) and (2) of this 
section for each emission capture system that contains bypass lines that 
could divert emissions away from the add-on control device to the 
atmosphere.
    (1) You must monitor or secure the valve or closure mechanism 
controlling the bypass line in a nondiverting position in such a way 
that the valve or closure mechanism cannot be opened without creating a 
record that the valve was opened. The method used to monitor or secure 
the valve or closure mechanism must meet one of the requirements 
specified in paragraphs (b)(1)(i) through (iv) of this section.
    (i) Flow control position indicator. Install, calibrate, maintain, 
and operate according to the manufacturer's specifications a flow 
control position indicator that takes a reading at least once every 15 
minutes and provides a record indicating whether the emissions are 
directed to the add-on control device or diverted from the add-on 
control device. The time of occurrence and flow control position must be 
recorded, as well as every time the flow direction is changed. The flow 
control position indicator must be installed at the entrance to any 
bypass line that could divert the emissions away from the add-on control 
device to the atmosphere.
    (ii) Car-seal or lock-and-key valve closures. Secure any bypass line 
valve in the closed position with a car-seal or a lock-and-key type 
configuration. You must visually inspect the seal or closure mechanism 
at least once every month to ensure that the valve is maintained in the 
closed position and the emissions are not diverted away from the add-on 
control device to the atmosphere.

[[Page 643]]

    (iii) Valve closure monitoring. Ensure that any bypass line valve is 
in the closed (non-diverting) position through monitoring of valve 
position at least once every 15 minutes. You must inspect the monitoring 
system at least once every month to verify that the monitor will 
indicate valve position.
    (iv) Automatic shutdown system. Use an automatic shutdown system in 
which the coating operation is stopped when flow is diverted by the 
bypass line away from the add-on control device to the atmosphere when 
the coating operation is running. You must inspect the automatic 
shutdown system at least once every month to verify that it will detect 
diversions of flow and shutdown the coating operation.
    (2) If any bypass line is opened, you must include a description of 
why the bypass line was opened and the length of time it remained open 
in the semiannual compliance reports required in Sec. 63.4120.
    (c) Thermal oxidizers and catalytic oxidizers. If you are using a 
thermal oxidizer or catalytic oxidizer as an add-on control device 
(including those used with concentrators or with carbon adsorbers to 
treat desorbed concentrate streams), you must comply with the 
requirements in paragraphs (a) and (c)(1) through (3) of this section:
    (1) For a thermal oxidizer, install a gas temperature monitor in the 
firebox of the thermal oxidizer or in the duct immediately downstream of 
the firebox before any substantial heat exchange occurs.
    (2) For a catalytic oxidizer, install a gas temperature monitor in 
the gas stream immediately before the catalyst bed, and if you establish 
operating limits according to Sec. 63.6167(b)(1) and (2), also install 
a gas temperature monitor in the gas stream immediately after the 
catalyst bed.
    (3) For each gas temperature monitoring device, you must comply with 
the requirements in paragraphs (c)(3)(i) through (vii) of this section.
    (i) Locate the temperature sensor in a position that provides a 
representative temperature.
    (ii) Use a temperature sensor with a measurement sensitivity of 4 
degrees Fahrenheit or 0.75 percent of the temperature value, whichever 
is larger.
    (iii) Shield the temperature sensor system from electromagnetic 
interference and chemical contaminants.
    (iv) If a gas temperature chart recorder is used, it must have a 
measurement sensitivity in the minor division of at least 20 degrees 
Fahrenheit.
    (v) Perform an electronic calibration at least semiannually 
according to the procedures in the manufacturer's owners manual. 
Following the electronic calibration, you must conduct a temperature 
sensor validation check in which a second or redundant temperature 
sensor placed nearby the process temperature sensor must yield a reading 
within 30 degrees Fahrenheit of the process temperature sensor's 
reading.
    (vi) Any time the sensor exceeds the manufacturer's specified 
maximum operating temperature range, either conduct calibration and 
validation checks or install a new temperature sensor.
    (vii) At least monthly, inspect components for integrity and 
electrical connections for continuity, oxidation, and galvanic 
corrosion.
    (d) Carbon adsorbers. If you are using a carbon adsorber as an add-
on control device, you must monitor the total regeneration desorbing gas 
(e.g., steam or nitrogen) mass flow for each regeneration cycle, the 
carbon bed temperature after each regeneration and cooling cycle, and 
comply with paragraphs (a)(3) through (5) and (d)(1) and (2) of this 
section.
    (1) The regeneration desorbing gas mass flow monitor must be an 
integrating device having a measurement sensitivity of plus or minus 10 
percent, capable of recording the total regeneration desorbing gas mass 
flow for each regeneration cycle.
    (2) The carbon bed temperature monitor must have a measurement 
sensitivity of 1 percent of the temperature recorded or 1 degree 
Fahrenheit, whichever is greater, and must be capable of recording the 
temperature within 15 minutes of completing any carbon bed cooling 
cycle.
    (e) Condensers. If you are using a condenser, you must monitor the 
condenser outlet (product side) gas temperature and comply with 
paragraphs (a) and (e)(1) and (2) of this section.
    (1) The gas temperature monitor must have a measurement sensitivity

[[Page 644]]

of 1 percent of the temperature recorded or 1 degree Fahrenheit, 
whichever is greater.
    (2) The temperature monitor must provide a gas temperature record at 
least once every 15 minutes.
    (f) Concentrators. If you are using a concentrator, such as a 
zeolite wheel or rotary carbon bed concentrator, you must comply with

the General Provisions of this part, and in this section as follows:
    Add-on control device means an air pollution control device, such as 
a thermal oxidizer or carbon absorber, that reduces pollution in an air 
stream by destruction or removal before discharge to the atmosphere.
    Adhesive means any chemical substance that is applied for the 
purpose of bonding two surfaces together.
    Capture device means a hood, enclosure, room, floor sweep, or other 
means of containing or collecting emissions and directing those 
emissions into an add-on control device.
    Capture efficiency or capture system efficiency means the portion 
(expressed as a percentage) of the pollutants from an emission source 
that is delivered to an add-on control device.
    Capture system means one or more capture devices intended to collect 
emissions generated by a coating operation in the use of coatings and 
cleaning materials, both at the point of application and at subsequent 
points where emissions from the coatings and cleaning materials occur, 
such as flashoff, drying, or curing. As used in this subpart, multiple 
capture devices that collect emissions generated by a coating operation 
are considered a single capture system.
    Cleaning material means a solvent used to remove contaminants and 
other materials such as dirt, grease, oil, and dried or wet coating 
(e.g., depainting) from a substrate before or after coating application 
or from equipment associated with a coating operation such as spray 
booths, spray guns, racks, tanks, and hangers. Thus, it includes 
cleaning materials used for substrates or equipment or both.
    Coating means a material applied to a substrate for decorative, 
protective, or functional purposes. For the purposes of this subpart, 
coatings include paints, porcelain enamels, sealants, caulks, inks, 
adhesives, and maskants. Decorative, protective, or functional materials 
that consist only of protective oils, acids, bases, or any combination 
of these substances are not considered coatings for the purposes of this 
subpart.
    Coating operation means equipment used to apply cleaning materials 
to a substrate to prepare it for coating application or to remove dried 
coating (surface preparation), to apply coating to a substrate (coating 
application) and to dry or cure the coating after application, or to 
clean coating operation equipment (equipment cleaning). A single coating 
operation may include any combination of these types of equipment but 
always includes at least the point at which a coating or cleaning 
material is applied and all subsequent points in the affected source 
where organic HAP emissions from that coating or cleaning material 
occur. There may be multiple coating operations in an affected source. 
Applications of coatings using hand-held, nonrefillable aerosol 
containers, touchup markers, or marking pens are not coating operations 
for the purposes of this subpart.
    Coating solids means the nonvolatile portion of the coating that 
makes up the dry film.
    Continuous parameter monitoring system means the total equipment 
that may be required to meet the data acquisition and availability 
requirements

[[Page 646]]

of this subpart used to sample, condition (if applicable), analyze, and 
provide a record of coating operation, capture system, or add-on control 
device parameters.
    Controlled coating operation means a coating operation from which 
some or all of the organic HAP emissions are routed through an emission 
capture system and add-on control device.
    Deviation means any instance in which an affected source subject to 
this subpart or an owner or operator of such a source:
    (1) Fails to meet any requirement or obligation established by this 
subpart including but not limited to any emission limit, or operating 
limit, or work practice standard;
    (2) Fails to meet any term or condition that is adopted to implement 
an applicable requirement in this subpart and that is included in the 
operating permit for any affected source required to obtain such a 
permit; or
    (3) Fails to meet any emission limit, or operating limit, or work 
practice standard in this subpart during startup, shutdown, or 
malfunction regardless of whether or not such failure is permitted by 
this subpart.
    Emission limitation means an emission limit, operating limit, or 
work practice standard.
    Enclosure means a structure that surrounds a source of emissions and 
captures and directs the emissions to an add-on control device.

VOC due to negligible photochemical reactivity. The exempt compounds are 
listed in 40 CFR 51.100(s).
    Facility maintenance means the routine repair or refurbishing 
(including surface coating) of the tools, equipment, machinery, and 
structures that comprise the infrastructure of the facility or that are 
necessary for the facility to function in its intended capacity. It does 
not mean cleaning of equipment that is part of a large appliances 
coating operation.

 Subpart OOOO_National Emission Standards for Hazardous Air Pollutants: 
       Printing, Coating, and Dyeing of Fabrics and Other Textiles

    Source: 68 FR 32189, May 29, 2003, unless otherwise noted.

                        What This Subpart Covers



Sec. 63.4280  What is the purpose of this subpart?

    This subpart establishes national emission standards for hazardous 
air pollutants (NESHAP) for fabric and other textiles printing, coating 
and dyeing operations. This subpart also establishes requirements to 
demonstrate initial and continuous compliance with the emission 
limitations.



Sec. 63.4281  Am I subject to this subpart?

    (a) Except as provided in paragraphs (c) and (d) of this section, 
the source category to which this subpart applies is the printing, 
coating, slashing, dyeing or finishing of fabric and other textiles, and 
it includes the subcategories listed in paragraphs (a)(1) through (3) of 
this section.

[[Page 653]]

    (1) The coating and printing subcategory includes any operation that 
coats or prints fabric or other textiles. Coating and printing 
operations are defined in Sec. 63.4371. Coated and printed substrates 
are used in products including, but not limited to, architectural 
structures, apparel, flexible hoses, hot-air balloons, lightweight 
liners, luggage, military fabric, rainwear, sheets, tents, threads and 
V-belts. The coating and printing subcategory includes any fabric or 
other textile web coating line that also performs coating on another 
substrate unless such coating is specifically excluded from this subpart 
by another NESHAP in this part or is exempted from the requirements of 
this subpart based on the criteria in paragraph (e) of this section. Web 
coating lines exclusively dedicated to coating or printing fabric and 
other textiles are subject to this subpart.
    (2) The slashing subcategory includes any operation with slashing 
operations as defined in Sec. 63.4371. In the slashing process, sizing 
compounds are applied to warp yarn to bind the fiber together and 
stiffen the yarn to provide abrasion resistance during weaving.
    (3) The dyeing and finishing subcategory includes any operation that 
dyes or finishes a fabric or other textiles. Dyeing and finishing 
operations are defined in Sec. 63.4371. Dyed and finished textiles are 
used in a wide range of products including, but not limited to, apparel, 
carpets, high-performance industrial fabrics, luggage, military fabrics, 
outer wear, sheets, towels, and threads.
    (b) You are subject to this subpart if you own or operate a new, 
reconstructed, or existing affected source, as defined in Sec. 63.4282, 
that is a major source, is located at a major source, or is part of a 
major source of hazardous air pollutants (HAP). Major source is defined 
in Sec. 63.2 of this part.
    (c) This subpart does not apply to coating, printing, slashing, 
dyeing, or finishing operations that meet any of the criteria of 
paragraphs (c)(1) through (5) of this section.
    (1) Coating and printing, slashing, or dyeing and finishing 
operations conducted at a source that uses only regulated materials that 
contain no organic HAP as defined in Sec. 63.4371.
    (2) Coating, printing, slashing, dyeing, or finishing that occurs at 
research or laboratory operations or that is part of janitorial, 
building, and facility maintenance operations.
    (3) Coating, printing, slashing, dyeing, or finishing operations 
used by a facility and not for commerce, unless organic HAP emissions 
from the coating, printing, slashing, dyeing or finishing operations are 
as high as the major source HAP emissions specified in paragraph (b) of 
this section.
    (4) Fabric and other textile substrate web coating or printing 
operations conducted at ambient temperatures that do not involve drying 
or curing equipment such as ovens, tenter frames, steam cans, or dryers.
    (5) Coating, printing, slashing, dyeing, or finishing operations 
performed on-site at installations owned or operated by the Armed Forces 
of the United States (including the Coast Guard and the National Guard 
of any State).
    (d) Web coating lines specified in paragraphs (d)(1) through (4) of 
this section are not part of the affected source of this subpart.
    (1) Any web coating operation that is part of the affected source of 
subpart JJJJ of this part (national emission standards for hazardous air 
pollutants for paper and other web coating). This would include any web 
coating line that coats both a paper and other web substrate and a 
fabric or other textile substrate for use in flexible packaging, 
pressure sensitive tape and abrasive materials, or any web coating line 
laminating a fabric substrate to paper.
    (2) Any web coating operation that is part of the affected source of 
subpart XXXX of this part (NESHAP for tire manufacturing). This would 
include any web coating line that applies coatings to both tire cord and 
to textile cord used in the production of belts and hoses.
    (3) Coating, slashing, dyeing, or finishing operations at a 
synthetic fiber manufacturing facility where the fibers are the final 
product of the facility.
    (4) Any web coating line that coats or prints fabric or other 
textiles for use in flexible packaging and that is included in an 
affected source under subpart KK

[[Page 654]]

of this part (National Emission Standards for the Printing and 
Publishing Industry).
    (e) Any web coating line that coats both fabric and other textiles, 
and another substrate such as paper, must comply with the subpart of 
this part that applies to the predominant activity conducted on the 
affected source. Predominant activity for this subpart is 90 percent of 
the mass of substrate coated during the compliance period. (For example, 
a web coating line that coats 90 percent or more of a paper substrate, 
and 10 percent or less of a fabric or other textile substrate, would be 
subject to 40 CFR 63, subpart JJJJ.)

specified in paragraphs (a) through (c) of this section. The compliance 
date begins the initial compliance period during which you conduct the 
initial compliance demonstration described in Sec. Sec. 63.4320, 
63.4330, 63.4340, and 63.4350.
    (a) For a new or reconstructed affected source, the compliance date 
is the applicable date in paragraph (a)(1) or (2) of this section:
    (1) If the initial startup of your new or reconstructed affected 
source is before May 29, 2003, the compliance date is May 29, 2003.
    (2) If the initial startup of your new or reconstructed affected 
source occurs after May 29, 2003, the compliance date is the date of 
initial startup of your affected source.
    (b) For an existing affected source, the compliance date is the date 
3 years after May 29, 2003.
    (c) For an area source that increases its emissions or its potential 
to emit such that it becomes a major source of HAP emissions, the 
compliance date is specified in paragraphs (c)(1) and (2) of this 
section.
    (1) For any portion of the source that becomes a new or 
reconstructed affected source subject to this subpart, the compliance 
date is the date of initial startup of the affected source or May 29, 
2003, whichever is later.
    (2) For any portion of the source that becomes an existing affected 
source subject to this subpart, the compliance date is the date 1 year 
after the area source becomes a major source or 3 years after May 29, 
2003, whichever is later.
    (d) You must meet the notification requirements in Sec. 63.4310 
according to the dates specified in that section and in subpart A of 
this part. Some of the notifications must be submitted before the 
compliance dates described in paragraphs (a) through (c) of this 
section.

                          Emission Limitations



Sec. 63.4290  What emission limits must I meet?

    You must meet the emission limit for the subcategory or 
subcategories present in your facility. The three subcategories are: Web 
coating and printing, slashing, and dyeing and finishing. Table 1 to 
this subpart presents the emission limits for a new or reconstructed 
affected source and for an existing affected source in each subcategory.



Sec. 63.4291  What are my options for meeting the emission limits?

    You must include all regulated materials (as defined in Sec. 
63.4371) used in the affected source when determining whether the 
organic HAP emission rate is equal to or less than the applicable 
emission limit in Table 1 to this subpart. To make this determination, 
you must use at least one of the compliance options for the subcategory 
listed in paragraphs (a) through (c) of this section.
    (a) Web coating and printing. You may apply any one of the 
compliance options in paragraphs (a)(1) through (5) of

[[Page 656]]

this section to an individual web coating/printing operation, or to 
multiple web coating/printing operations in the affected source as a 
group, or to the entire affected source in the web coating and printing 
subcategory. You may use different compliance options for different web 
coating/printing operations or at different times on the same web 
coating/printing operation. However, you may not use different 
compliance options at the same time on the same web coating/printing 
operation. If you switch between compliance options for any web coating/
printing operation or group of operations, you must document this switch 
as required by Sec. 63.4312(c), and you must report it in the next 
semiannual compliance report required in Sec. 63.4311.
    (1) Compliant material option. Demonstrate that the organic HAP 
content, as purchased, of each coating and printing material applied in 
the web coating/printing operation(s) is less than or equal to the 
applicable emission limit in Table 1 to this subpart, and that each 
thinning and cleaning material as purchased contains no organic HAP (as 
defined in Sec. 63.4371). You must meet all the requirements of 
Sec. Sec. 63.4320, 63.4321, and 63.4322 to demonstrate compliance with 
the applicable emission limit using this option.
    (2) Emission rate without add-on controls option. Demonstrate that, 
based on the regulated materials applied in the web coating/printing 
operation(s), the organic HAP emission rate for the web coating/printing 
operation(s) is less than or equal to the applicable emission limit in 
Table 1 to this subpart, calculated as a rolling 12-month average 
emission rate. You must meet all the requirements of Sec. Sec. 63.4330, 
63.4331, and 63.4332 to demonstrate compliance with the applicable 
emission limit using this option.
    (3) Emission rate with add-on controls option. Demonstrate that, 
based on the regulated materials applied in the web coating/printing

        Compliance Requirements for the Compliant Material Option



Sec. 63.4320  By what date must I conduct the initial compliance
demonstration?

    You must complete the compliance demonstration for the initial 
compliance period according to the requirements in Sec. 63.4321. The 
initial compliance period begins on the applicable compliance date 
specified in Sec. 63.4283 and ends on the last day of the first full 
month after the compliance date. The initial compliance demonstration 
includes the calculations according to Sec. 63.4321 and supporting 
documentation showing that, during the initial compliance period, the 
organic HAP content of each coating and printing material you applied 
and the mass fraction of organic HAP in each slashing, dyeing, and 
finishing material you applied did not exceed the applicable limit in 
Table 1 to this subpart, and documentation that in web coating/printing 
operations you applied only thinners and cleaners that contained no 
organic HAP as defined in Sec. 63.4371.



Sec. 63.4321  How do I demonstrate initial compliance with the emission
limitations?

    (a) You may use the compliant material option for any individual web 
coating/printing operation, for any group of web coating/printing 
operations in the affected source, or for all the web coating/printing 
operations in the affected source. You must use either the emission rate 
without add-on controls option, the emission rate with add-on controls 
option, the organic HAP overall control efficiency option, or the 
oxidizer outlet organic HAP concentration option for any web coating/
printing operation(s) in the affected source for which you do not use 
this option. For a web coating/printing affected source to demonstrate 
initial compliance using the compliant material option, the web coating/
printing operation or group of web coating/printing operations must 
apply no coating or printing material with an organic HAP content that 
exceeds the applicable emission limit in Table 1 to this subpart and 
must apply only thinning or cleaning material that contains no organic 
HAP, as defined in Sec. 63.4371.
    (b) You must use the compliant material option for each slashing 
affected source, as required in Table 1 to this subpart. For a slashing 
affected source to demonstrate initial compliance using the compliant 
material option, the slashing operation or group of slashing operations 
must apply only slashing material with no organic HAP as defined in 
Sec. 63.4371.
    (c) You may use the compliant material option for any individual 
dyeing/finishing operation, for any group of dyeing/finishing operations 
in the affected source, or for all the dyeing/finishing operations in 
the affected source. You must use either the emission rate without add-
on controls option or the emission rate with add-on controls option for 
any dyeing/finishing operations in the affected source for which you do 
not use this option. You may not use the compliant material option for 
any dyeing/finishing operation in a dyeing/finishing affected source for 
which you use the equivalent emission rate option. For a dyeing/
finishing affected source to demonstrate initial compliance using the 
compliant material option, the dyeing/finishing operation or group of 
dyeing/finishing operations must apply no dyeing or finishing material 
with a mass fraction of organic HAP that exceeds the applicable emission 
limit in Table 1 to this subpart.
    (d) Any web coating/printing operation, slashing operation, or 
dyeing/finishing operation for which you use the compliant material 
option is not required to meet the operating limits or work practice 
standards required in Sec. Sec. 63.4292 and 63.4293, respectively.
    (e) To demonstrate initial compliance with the emission limitations 
using the compliant material option, you must meet all the requirements 
of this section for any web coating/printing operation, slashing 
operation, or dyeing/finishing operation using this option. Use the 
applicable procedures in this section on each regulated material in the 
condition it is in when it is received from its manufacturer or supplier 
and prior to any alteration. You do not need to redetermine the organic 
HAP content of regulated materials

[[Page 670]]

that are reclaimed onsite and reused in the web coating/printing 
operation, slashing operation, or dyeing/finishing operation for which 
you use the compliant material option, provided these regulated 
materials in their condition as received were demonstrated to comply 
with the compliant material option.
    (1) Determine the mass fraction of organic HAP for each material. 
You must determine the mass fraction of organic HAP for each regulated 
material applied during the compliance period by using one of the 
options in paragraphs (e)(1)(i) through (v) of this section. You must 
use the option in paragraph (e)(1)(iv) of this section for each 
printing, slashing, dyeing, or finishing material applied during the 
compliance period.
    (i) Method 311 (appendix A to 40 CFR part 63). You may use Method 
311 for determining the mass fraction of organic HAP. Use the procedures 
specified in paragraphs (e)(1)(i)(A) and (B) of this section when 
performing a Method 311 test.
    (A) Count each organic HAP that is measured to be present at 0.1 
percent by mass or more for Occupational Safety and Health 
Administration (OSHA)-defined carcinogens as specified in 29 CFR 
1910.1200(d)(4) and at 1.0 percent by mass or more for other compounds. 
For example, if toluene (not an OSHA carcinogen) is measured to be 0.5 
percent of the material by mass, you don't have to count it. Express the 
mass fraction of each organic HAP you count as a value truncated to no 
more than four places after the decimal point (e.g., 0.3791).
    (B) Calculate the total mass fraction of organic HAP in the 
regulated material being tested by adding up the individual organic HAP 
mass fractions and truncating the result to no more than three places 
after the decimal point (e.g., 0.763).
    (ii) Method 24 (appendix A to 40 CFR part 60). You may use Method 24 
to determine the mass fraction of nonaqueous volatile matter and use 
that value as a substitute for mass fraction of organic HAP. For a 
multi-component coating with reactive chemicals, you may use Method 24 
on the coating as applied to determine the mass fraction of nonaqueous 
volatile matter and use that value as a substitute for the mass fraction 
of organic HAP determined from the sum of organic HAP in each component.
    (iii) Alternative method. You may use an alternative test method for 
determining the mass fraction of organic HAP, mass fraction of solids, 
or fraction of organic HAP emitted from a reactive coating once the 
Administrator has approved it. You must follow the procedure in Sec. 
63.7(f) to submit an alternative test method for approval.
    (iv) Information from the supplier or manufacturer of the material. 
You may rely on information other than that generated by the test 
methods specified in paragraphs (e)(1)(i) through (iii) of this section, 
such as manufacturer's formulation data, if it represents each organic 
HAP that is present at 0.1 percent by mass or more for OSHA-defined 
carcinogens as specified in 29 CFR 1910.1200(d)(4) and at 1.0 percent by 
mass or more for other compounds. For example, if toluene (not an OSHA 
carcinogen) is 0.5 percent of the material by mass, you do not have to 
count it. If there is a disagreement between such information and 
results of a test conducted according to paragraphs (e)(1)(i) through 
(iii) of this section on coating, thinning, or cleaning material, then 
the test method results will take precedence. Information from the 
supplier or manufacturer of the printing, slashing, dyeing, or finishing 
material is sufficient for determining the mass fraction of organic HAP.
    (v) Solvent blends. Solvent blends may be listed as single 
components for some materials in data provided by manufacturers or 
suppliers. Solvent blends may contain organic HAP which must be counted 
toward the total organic HAP mass fraction of the materials. When test 
data and manufacturer's data for solvent blends are not available, you 
may use the default values for the mass fraction of organic HAP in these 
solvent blends listed in Table 4 or 5 to this subpart. If you use the 
tables, you must use the values in Table 4 for all solvent blends that 
match Table 4 entries, and you may only use Table 5 if the solvent 
blends in the materials you use do not match any of the solvent blends 
in Table 4 and you only know

[[Page 671]]

whether the blend is aliphatic or aromatic. However, if the results of a 
Method 311 test indicate higher values than those listed on Table 4 or 5 
to this subpart, the Method 311 results will take precedence.
    (2) Determine the mass fraction of solids for each coating and 
printing material. You must determine the mass fraction of solids (kg of 
solids per kg of coating or printing material) for each coating material 
applied during the compliance period by a test or by information 
provided by the supplier or the manufacturer of the material, as 
specified in paragraphs (e)(2)(i) through (iii) of this section. If test 
results obtained according to paragraph (e)(2)(i) or (ii) of this 
section for a coating material do not agree with the information 
obtained under paragraph (e)(2)(iii) of this section, the test results 
will take precedence. To determine mass fraction of solids for each 
printing material applied during the compliance period, you should use 
information provided by the supplier or manufacturer of the material, as 
specified in paragraph (e)(2)(iii) of this section.
    (i) Method 24 (appendix A to 40 CFR part 60). You may use Method 24 
for determining the mass fraction of solids of coating materials.
    (ii) Alternative method. You may use an alternative test method for 
determining solids content of each coating material once the 
Administrator has approved it. You must follow the procedure in Sec. 
63.7(f) to submit an alternative test method for approval.
    (iii) Information from the supplier or manufacturer of the material. 
You may obtain the mass fraction of solids for each coating and printing 
material from the supplier or manufacturer. If there is disagreement 
between such information and the test method results for a coating 
material, then the test method results will take precedence.
    (3) Calculate the organic HAP content of each coating or printing 
material. Calculate the organic HAP content, kg organic HAP per kg of 
solids, of each coating and printing material applied during the 
compliance period, using Equation 1 of this section:
[GRAPHIC] [TIFF OMITTED] TR29MY03.000

Where:

Hc = Organic HAP content of the coating or printing material, 
          kg organic HAP per kg solids in the coating or printing 
          material.
Wc = Mass fraction of organic HAP in the coating or printing 
          material, kg organic HAP per kg material, determined according 
          to paragraph (e)(1) of this section.
Wf = Mass fraction of solids in coating or printing material, 
          kg solids per kg of coating or printing material, determined 
          according to paragraph (e)(2) of this section.

    (4) Compliance demonstration. The calculated organic HAP content for 
each coating and printing material applied during the initial compliance 
period must be less than or equal to the applicable emission limit in 
Table 1 to this subpart, and each thinning and cleaning material applied 
during the initial compliance period must contain no organic HAP as 
defined in Sec. 63.4371. Each slashing material applied during the 
initial compliance period must contain no organic HAP as defined in 
Sec. 63.4371. The mass fraction of organic HAP for each dyeing and 
finishing material applied during the initial compliance period, 
determined according to paragraph (e)(1)(iv) of this section, must be 
less than or equal to the applicable emission limit in Table 1 to this 
subpart. You must keep all records required by Sec. Sec. 63.4312 and 
63.4313. As part of the Notification of Compliance Status required in 
Sec. 63.4310, you must:
    (i) Identify any web coating/printing operation, slashing operation, 
and dyeing/finishing operation for which you used the compliant material 
option;
    (ii) Submit a statement that the web coating/printing operation(s) 
was (were) in compliance with the emission limitations during the 
initial compliance period because you applied no coating and printing 
material for which the organic HAP content exceeds the applicable 
emission limit in Table 1 to this subpart, and you applied only thinning 
materials and cleaning materials that contained no organic HAP, as 
defined in Sec. 63.4371;
    (iii) Submit a statement that the slashing operation(s) was (were) 
in compliance with the emission limitations during the initial 
compliance period because you applied only slashing materials that 
contained no organic HAP, as defined in Sec. 63.4371; and

[[Page 672]]

    (iv) Submit a statement that the dyeing/finishing operation(s) was 
(were) in compliance with the emission limitations during the initial 
compliance period because you applied no dyeing and finishing material 
for which the mass fraction of organic HAP exceeds the applicable 
emission limit in Table 1 to this subpart.



Sec. 63.4322  How do I demonstrate continuous compliance with the
emission limitations?

    (a) For each compliance period, to demonstrate continuous 
compliance, you must apply no coating or printing material for which the 
organic HAP content determined using Equation 1 of Sec. 63.4321, 
exceeds the applicable emission limit in Table 1 to this subpart. For 
each compliance period, to demonstrate continuous compliance, you must 
apply only slashing material that contains no organic HAP as defined in 
Sec. 63.4371. For each compliance period, to demonstrate continuous 
compliance, you must apply no dyeing or finishing material for which the 
mass fraction of organic HAP, determined according to the requirements 
of Sec. 63.4321(e)(1)(iv), exceeds the applicable emission limit in 
Table 1 to this subpart. For each compliance period, you must apply only 
thinning or cleaning materials that contain no organic HAP (as defined 
in Sec. 63.4371) in a coating/printing affected source. Each month 
following the initial compliance period described in Sec. 63.4320 is a 
compliance period.
    (b) If you choose to comply with the emission limitations by using 
the compliant material option, the application of any regulated material 
that does not meet the criteria specified in paragraph (a) of this 
section is a deviation from the emission limitations that must be 
reported as specified in Sec. Sec. 63.4310(c)(6) and 63.4311(a)(5).
    (c) As part of each semiannual compliance report required by Sec. 
63.4311, you must identify any web coating/printing operation, slashing 
operation, or dyeing/finishing operation for which you used the 
compliant material option. If there were no deviations from the 
applicable emission limit in Table 1 to this subpart, submit a statement 
that, as appropriate, the web coating/printing operations were in 
compliance with the emission limitations during the reporting period 
because you applied no coating or printing material for which the 
organic HAP content exceeded the applicable emission limit in Table 1 to 
this subpart, and you applied only thinning and cleaning materials that 
contained no organic HAP (as defined in Sec. 63.4371) in a web coating/
printing affected source; the slashing operations were in compliance 
with the emission limitations during the reporting period because you 
applied only slashing materials with no organic HAP (as defined in Sec. 
63.4371) in a slashing affected source; and the dyeing/finishing 
operations were in compliance with the emission limitations during the 
reporting period because you applied no dyeing or finishing material for 
which the mass fraction of organic HAP exceeded the applicable emission 
limit in Table 1 to this subpart.
    (d) You must maintain records as specified in Sec. Sec. 63.4312 and 
63.4313.

 Compliance Requirements for the Emission Rate Without Add-On Controls 
                                 Option



Sec. 63.4330  By what date must I conduct the initial compliance
demonstration?

    You must complete the compliance demonstration for the initial 
compliance period according to the requirements of Sec. 63.4331. The 
initial compliance period begins on the applicable compliance date 
specified in Sec. 63.4283 and ends on the last day of the 12th full 
month after the compliance date. The initial compliance demonstration 
includes the calculations according to Sec. 63.4331 and supporting 
documentation showing that for web coating/printing operations, the 
organic HAP emission rate for the initial compliance period was equal to 
or less than the applicable emission limit in Table 1 to this subpart 
and for dyeing/finishing operations, the mass fraction of organic HAP 
for the initial compliance period was less than or equal to the 
applicable emission limit in Table 1 to this subpart.

[[Page 673]]



Sec. 63.4331  How do I demonstrate initial compliance with the emission
limitations?

    (a) For web coating/printing operations, you may use the emission 
rate without add-on controls option for any individual web coating/
printing operation, for any group of web coating/printing operations in 
the affected source, or for all the web coating/printing operations as a 
group in the affected source. You must use either the compliant material 
option, the emission rate with add-on controls option, the organic HAP 
overall control efficiency option, or the oxidizer outlet organic HAP 
concentration option for any web coating/printing operation in the 
affected source for which you do not use this option. To demonstrate 
initial compliance using the emission rate without add-on controls 
option, the web coating/printing operation or group of web coating/
printing operations must meet the applicable emission limit in Table 1 
to this subpart but is not required to meet the operating limits or work 
practice standards in Sec. Sec. 63.4292 and 63.4293, respectively. You 
must meet all the requirements of paragraphs (a)(1) through (7) of this 
section to demonstrate initial compliance with the applicable emission 
limit in Table 1 to this subpart for the web coating/printing 
operation(s). When calculating the organic HAP emission rate according 
to this section, do not include any coating, printing, thinning, or 
cleaning materials applied on web coating/printing operations for which 
you use the compliant material option, the emission rate with add-on 
controls option, the organic HAP overall control efficiency option, or 
the oxidizer outlet organic HAP concentration option. Use the procedures 
in this section on each regulated material in the condition it is in 
when it is received from its manufacturer or supplier and prior to any 
alteration.

in waste materials sent or designated for shipment to a hazardous waste 
TSDF in Equation 1 of this section, then you must determine it according 
to paragraphs (a)(4)(iii)(A) through (D) of this section.
    (A) You may include in the determination only waste materials that 
are generated by web coating/printing operations in the affected source 
for which you use Equation 1 of this section and that will be treated or 
disposed of by a facility that is regulated as a TSDF under 40 CFR part 
262, 264, 265, or 266. The TSDF may be either off-site or on-site. You 
may not include organic HAP contained in wastewater.
    (B) You must determine either the amount of the waste materials sent 
to a TSDF during the compliance period or the amount collected and 
stored during the compliance period designated for future transport to a 
TSDF. Do not include in your determination any waste materials sent to a 
TSDF during a compliance period if you have already included them in the 
amount collected and stored during that compliance period or a previous 
compliance period.
    (C) Determine the total mass of organic HAP contained in the waste 
materials specified in paragraph (a)(4)(iii)(B) of this section.
    (D) You must document the methodology you use to determine the

contain, as required in Sec. 63.4312(g). To the extent that waste 
manifests include this, they may be used as part of the documentation of 
the amount of waste materials and mass of organic HAP contained in them.
    (5) Calculate the total mass of coating and printing solids. 
Determine the total mass of coating and printing solids applied, kg, 
which is the combined mass of the solids contained in all the coating 
and printing materials applied during the compliance period, using

initial compliance period must be less than or equal to the applicable 
emission limit in Table 1 to this subpart. You must keep all records as 
required by Sec. Sec. 63.4312 and 63.4313. As part of the Notification 
of Compliance Status required by Sec. 63.4310, you must identify the 
web coating/printing operation(s) for which you used the emission rate 
without add-on controls option and submit a statement that the web 
coating/printing operation(s) was (were) in compliance with the emission 
limitations during the initial compliance period because the organic HAP 
emission rate was less than, or equal to, the applicable emission limit 
in Table 1 to this subpart.
    (b) For dyeing and finishing operations, you may use the emission 
rate without add-on controls option for any individual dyeing/finishing 
operation, for any group of dyeing/finishing operations in the affected 
source, or for dyeing/finishing operations as a group in the affected 
source. You must use either the compliant material option or the 
emission rate with add-on controls option for any dyeing/finishing 
operation in the affected source for which you do not use this option. 
You may not use the emission rate without add-on controls option for any 
dyeing/finishing operation in a dyeing/finishing affected source for 
which you use the equivalent emission rate option. To demonstrate 
initial compliance using the emission rate without add-on controls 
option, the dyeing/finishing operation or group of operations must meet 
the applicable emission limit in Table 1 to this subpart but is not 
required to meet the operating limits or work practice standards in

calculating the organic HAP emission rate according to this section, do 
not include any dyeing and finishing materials applied on dyeing/
finishing operations for which you use the compliant material option or 
the emission rate with add-on controls option. Use the procedures in 
this section on each regulated material in the condition it is in when 
it is received from its manufacturer or supplier and prior to any 
alteration. Water added in mixing at the affected source is not a 
regulated material and should not be included in the determination of

          wish to use this allowance.)
WW = Total mass of organic HAP in wastewater discharged to a POTW or 
          receiving onsite secondary treatment during the compliance 
          period, kg, determined according to paragraph (b)(3)(iii) of

manifests include this, they may be used as part of the documentation of 
the amount of waste materials and mass of organic HAP contained in them.
    (iii) If you choose to account for the mass of organic HAP contained 
in wastewater discharged to a POTW or treated onsite prior to discharge 
in Equation 4 of this section, then you must determine it according to

          compliance period, kg, as calculated by Equation 4 of this 
          section.
Mt = Total mass of dyeing and finishing materials applied 
          during the compliance period, kg, as calculated by Equation 5 
          of this section.

    (6) Compliance demonstration. The organic HAP emission rate for the 
initial compliance period must be less than or equal to the applicable 
emission limit

[[Page 677]]

in Table 1 to this subpart. You must keep all records as required by 
Sec. Sec. 63.4312 and 63.4313. As part of the Notification of 
Compliance Status required by Sec. 63.4310, you must identify the 
dyeing/finishing operation(s) for which you used the emission rate 
without add-on controls option and submit a statement that the dyeing/
finishing operation(s) was (were) in compliance with the emission 
limitations during the initial compliance period because the organic HAP 
emission rate was less than or equal to the applicable emission limit in 
Table 1 to this subpart.
    (i) If your affected source performs only dyeing operations, 
paragraphs (b)(1) through (5) of this section apply to dyeing materials 
only, and you must demonstrate compliance with the emission limit in 
Table 1 to this subpart for dyeing operations.
    (ii) If your affected source performs only finishing operations, 
paragraphs (b)(1) through (5) of this section apply to finishing 
materials only, and you must demonstrate compliance with the emission 
limit in Table 1 to this subpart for finishing operations.
    (iii) If your affected source performs both dyeing and finishing 
operations, paragraphs (b)(1) through (5) of this section apply to 
dyeing and finishing materials combined, and you must demonstrate 
compliance with the emission limit in Table 1 to this subpart for dyeing 
and finishing operations.
    (c) If you choose to account for the mass of organic HAP contained 
in wastewater discharged to a POTW or treated onsite prior to discharge 
in Equation 4 of this section, then you must determine it according to 
paragraphs (c)(1) through (5) of this section. You may include in the 
determination only wastewater streams that are generated by dyeing/
finishing operations in the affected source for which you use Equation 4 
of this section. You must determine the mass of organic HAP from the 
average organic HAP concentration and mass flow rate of each wastewater 
stream generated by the affected dyeing/finishing operation (or group of 
dyeing/finishing operations discharging to a common wastewater stream) 
for which you use this allowance. You must consider the actual or 
anticipated production over the compliance period and include all 
wastewater streams generated by the affected dyeing/finishing 
operation(s) during this period. A performance test of the organic HAP 
loading to the wastewater shall be performed for each operating 
scenario, as defined in Sec. 63.4371, during the compliance period.
    (1) Procedure to determine average organic HAP concentration. You 
must determine the average organic HAP concentration, Hw, of 
each wastewater stream according to paragraphs (c)(1)(i) through (vi) of 
this section.
    (i) Sampling. Wastewater samples may be grab samples or composite 
samples. Samples shall be taken at approximately equally spaced time 
intervals over a 1-hour period (or over the period that wastewater is 
being discharged from a batch process if it is shorter than a 1-hour 
period). Each 1-hour period constitutes a run, and a performance test 
shall consist of a minimum of 3 runs.
    (ii) Methods. You may use any of the methods specified in paragraphs 
(c)(1)(ii)(A) through (E) of this section to determine the organic HAP 
content of the wastewater stream. The method shall be an analytical 
method for wastewater which has the organic HAP compound discharged to 
the wastewater as a target analyte.
    (A) Method 305. Use procedures specified in Method 305 of 40 CFR 
part 63, appendix A.
    (B) Methods 624 and 625. Use procedures specified in Method 624 and 
Method 625 of 40 CFR part 136, appendix A and comply with the sampling 
protocol requirements specified in paragraph (c)(1)(iii) of this 
section. If these methods are used to analyze one or more compounds that 
are not on the method's published list of approved compounds, the 
Alternative Test Procedure specified in 40 CFR 136.4 and 136.5 shall be 
followed. For Method 625, make corrections to the compounds for which 
the analysis is being conducted based on the accuracy as recovery 
factors in Table 7 of the method.
    (C) Methods 1624 and 1625. Use procedures specified in Method 1624 
and Method 1625 of 40 CFR part 136, appendix A and comply with the 
sampling protocol requirements specified in paragraph (c)(1)(iii) of 
this section. If

[[Page 678]]

these methods are used to analyze one or more compounds that are not on 
the method's published list of approved compounds, the Alternative Test 
Procedure specified in 40 CFR 136.4 and 136.5 shall be followed.
    (D) Other EPA method(s). Use procedures specified in the method and 
comply with the requirements specified in paragraphs (c)(1)(iii) and 
either paragraph (c)(1)(iv)(A) or (B) of this section.
    (E) Methods other than EPA method. Use procedures specified in the 
method and comply with the requirements specified in paragraphs 
(c)(1)(iii) and paragraph (c)(1)(iv)(A) of this section.
    (iii) Sampling plan. If you have been expressly referred to this 
paragraph by provisions of this subpart, you shall prepare a sampling 
plan. Wastewater samples shall be collected using sampling procedures 
which minimize loss of organic compounds during sample collection and 
analysis and maintain sample integrity. The sampling plan shall include 
procedures for determining recovery efficiency of the relevant organic 
HAP. An example of an example sampling plan would be one that 
incorporates similar sampling and sample handling requirements to those 
of Method 25D of 40 CFR part 60, appendix A. You shall maintain the 
sampling plan at the facility.
    (iv) Validation of methods. You shall validate EPA methods other 
than Methods 305, 624, 625, 1624, 1625 using the procedures specified in 
paragraph (c)(1)(iv)(A) or (B) of this section.
    (A) Validation of EPA methods and other methods. The method used to 
measure organic HAP concentrations in the wastewater shall be validated 
according to section 5.1 or 5.3, and the corresponding calculations in 
section 6.1 or 6.3, of Method 301 of appendix A of this part. The data 
are acceptable if they meet the criteria specified in section 6.1.5 or 
6.3.3 of Method 301 of appendix A of this part. If correction is 
required under section 6.3.3 of Method 301 of appendix A of this part, 
the data are acceptable if the correction factor is within the range 0.7 
to 1.30. Other sections of Method 301 of appendix A of this part are not 
required.
    (B) Validation for EPA methods. Follow the procedures as specified 
in ``Alternative Validation Procedure for EPA Waste Methods'' 40 CFR 
part 63, appendix D.
    (v) Calculate the average concentration. You shall calculate the 
average concentration for each individually speciated organic HAP 
compound by adding the individual values determined for the specific 
compound in each sample and dividing by the number of samples.
    (vi) Adjustment for concentrations determined downstream of the 
point of determination. You shall make corrections to the specific 
compound average concentration or total organic HAP average 
concentration when the concentration is determined downstream of the 
point of determination at a location where either wastewater streams 
from outside of the affected dyeing/finishing operation or group of 
dyeing/finishing operations have been mixed with the affected wastewater 
stream or one or more affected wastewater streams have been treated. You 
shall make the adjustments either to the individual data points or to 
the final average organic HAP concentration.
    (2) Procedures to determine mass flow rate. For each operating 
scenario, as defined in Sec. 63.4371, for which you have determined the 
organic HAP content of the wastewater stream, you shall determine the 
annual average mass flow rate, Fw, of the wastewater stream 
either at the point of determination or downstream of the point of 
determination with adjustment for flow rate changes made according to 
paragraph (c)(2)(ii) of this section. The annual average mass flow rate 
for the wastewater stream shall be representative of actual or 
anticipated operation of the dyeing/finishing operation(s) generating 
the wastewater over the compliance period. You must determine the annual 
average mass flow rate of each wastewater stream according to paragraphs 
(c)(2)(i) and (ii) of this section.
    (i) Procedures. The procedures specified in paragraphs (c)(2)(i)(A) 
through (C) of this section are considered acceptable procedures for 
determining the mass flow rate. They may be used in combination, and no 
one procedure shall take precedence over another.
    (A) Knowledge of the wastewater. You may use knowledge of the 
wastewater stream and/or the process to determine the annual average 
mass flow rate. You

[[Page 679]]

shall use the maximum expected annual average production capacity of the 
dyeing/finishing operation(s), knowledge of the process, and/or mass 
balance information to either estimate directly the average wastewater 
mass flow rate for the compliance period or estimate the total 
wastewater mass flow for the compliance period and then factor the total 
mass by the percentage of time in the compliance period the operating 
scenario is expected to represent. Where you use knowledge to determine 
the annual average mass flow rate, you shall provide sufficient 
information to document the mass flow rate.
    (B) Historical records. You may use historical records to determine 
the average annual mass flow rate. Derive the highest annual average 
mass flow rate of wastewater from historical records representing the 
most recent 5 years of operation, or if the dyeing/finishing 
operation(s) has(have) been in service for less than 5 years but at 
least 1 year, from historical records representing the total operating 
life of the process unit. Where historical records are used to determine 
the annual average mass flow rate, you shall provide sufficient 
information to document the mass flow rate.
    (C) Measurement of mass flow rate. If you elect to measure mass flow 
rate, you shall comply with the requirements of this paragraph. 
Measurements shall be made at the point of determination, or at a 
location downstream of the point of determination with adjustments for 
mass flow rate changes made according to paragraph (c)(2)(ii) of this 
section. Where measurement data are used to determine the annual average 
mass flow rate, you shall provide sufficient information to document the 
mass flow rate.
    (ii) Adjustment for flow rates determined downstream of the point of 
determination. You shall make corrections to the average annual mass 
flow rate of a wastewater stream when it is determined downstream of the 
point of determination at a location where either wastewater streams 
from outside of the affected dyeing/finishing operation or group of 
dyeing/finishing operations have been mixed with the affected wastewater 
stream or one or more wastewater streams have been treated. You shall 
make corrections for such changes in the annual average mass flow rate.
    (3) Wastewater treatment. You shall document that the wastewater is 
either discharged to a POTW or onsite secondary wastewater treatment.
    (4) Determine the mass of organic HAP in the affected wastewater. 
Determine the total mass of organic HAP, WW, contained in the wastewater 
streams characterized by the procedures in paragraphs (c)(1) and (2) of 
this section, using Equation 7 of this section:
[GRAPHIC] [TIFF OMITTED] TR29MY03.010

Where:

WW = The total mass of organic HAP contained in the wastewater streams 
          characterized by the procedures in paragraphs (c)(1) and (2) 
          of this section, kg/yr
Hw,k = Average organic HAP concentration of wastewater stream 
          k, ppmw
Fw,k = Annual average mass flow rate of wastewater stream k, 
          Mg/yr
o = Number of wastewater streams characterized by the procedures in 
          paragraphs (c)(1) and (2) of this section.

    This is your allowance for organic HAP discharged to wastewater and 
not emitted to the atmosphere, WW in Equation 4.
    (5) Determine the fraction of organic HAP applied that is discharged 
to the wastewater. For the purpose of taking credit for the wastewater 
allowance in continuous compliance demonstrations, determine the 
fraction of organic HAP applied in affected dyeing/finishing processes 
that is discharged to the wastewater, i.e., divide WW by the mass of 
organic HAP in the dyeing and finishing materials applied during the 
compliance period, A, as calculated in Equation 4A of this section. The 
wastewater allowance for this fraction of organic HAP that is not 
emitted from the affected dyeing/finishing operation(s) may be taken for 
each compliance period that the operating scenario, as defined in Sec. 
63.4371, does not change from conditions during the performance test in 
a way that could increase the fraction of organic HAP emitted (e.g., an 
increase in process temperature or decrease in process pressure or a 
change in the type or mass fraction of organic

[[Page 680]]

HAP entering the dyeing/finishing operation.) The allowance, WW, must be 
calculated by multiplying the fraction of organic HAP applied in 
affected processes that is discharged to the wastewater determined from 
the most recent performance test by the mass of organic HAP in the 
dyeing and finishing materials applied during the compliance period, A, 
as calculated in Equation 4A of this section.
    (d) If you are determining the fraction of organic HAP applied in 
your dyeing/finishing affected source that is discharged to the 
wastewater, to demonstrate compliance with the equivalent emission rate 
option of Sec. 63.4291(c)(4), then you must determine it according to 
paragraphs (d)(1) through (5) of this section. You must include in the 
determination only wastewater streams generated by dyeing/finishing 
operations in your affected source. You shall determine the mass of 
organic HAP from the average organic HAP concentration and mass flow 
rate of each wastewater stream generated by each dyeing/finishing 
operation (or group of dyeing/finishing operations discharging to a 
common wastewater stream) in your affected source. You shall consider 
the actual or anticipated production over the compliance period and 
include all wastewater streams generated by the affected dyeing/
finishing operation(s) during this period. A performance test of the 
organic HAP loading to the wastewater shall be conducted for each 
operating scenario, as defined in Sec. 63.4371, during the compliance 
period.
    (1) Procedure to determine average organic HAP concentration. You 
must determine the average organic HAP concentration of each wastewater 
stream according to paragraphs (c)(1)(i) through (vi) of this section.
    (2) Procedures to determine mass flow rate. For each operating 
scenario, as defined in Sec. 63.4371, for which you have determined the 
organic HAP content of the wastewater stream, you shall determine the 
annual average mass flow rate of the wastewater stream either at the 
point of determination, or downstream of the point of determination with 
adjustment for flow rate changes made according to paragraph (c)(2)(ii) 
of this section. The annual average mass flow rate for the wastewater 
stream shall be representative of actual or anticipated operation of the 
dyeing/finishing operation(s) generating the wastewater over the 
compliance period. You must determine the annual average mass flow rate 
of each wastewater stream according to paragraphs (c)(2)(i) and (ii) of 
this section.
    (3) Wastewater treatment. You shall document that the wastewater is 
either discharged to a POTW or onsite secondary wastewater treatment.
    (4) Determine the mass of organic HAP in the affected wastewater. 
Determine the total mass of organic HAP, WW, contained in the wastewater 
streams characterized by the procedures in paragraphs (d)(1) and (2) of 
this section, using Equation 7 of this section.
    (5) Determine the fraction of organic HAP applied that is discharged 
to the wastewater. Determine the fraction of organic HAP applied in your 
dyeing/finishing affected source that is discharged to the wastewater, 
i.e., divide WW by the mass of organic HAP in the dyeing and finishing 
materials applied during the compliance period, A, as calculated in 
Equation 4A of this section. One of the conditions that must be met to 
demonstrate compliance with the equivalent emission rate option is that 
the fraction of organic HAP applied in your dyeing/finishing affected 
source that is discharged to the wastewater must be at least 90 percent.



Sec. 63.4332  How do I demonstrate continuous compliance with the
emission limitations?

    (a) To demonstrate continuous compliance, the organic HAP emission 
rate for each compliance period, determined according to Sec. 
63.4331(a) for web coating/printing operations and according to Sec. 
63.4331(b) for dyeing/finishing operations, must be less than or equal 
to the applicable emission limit in Table 1 to this subpart. Each month 
following the initial compliance period described in Sec. 63.4330 is a 
compliance period consisting of that month and the preceding 11 months. 
You must perform the calculations in Sec. 63.4331 on a monthly basis.
    (b) If the organic HAP emission rate for any compliance period 
exceeded the

[[Page 681]]

applicable emission limit in Table 1 to this subpart, this is a 
deviation from the emission limitations for that compliance period and 
must be reported as specified in Sec. Sec. 63.4310(c)(6) and 
63.4311(a)(6).
    (c) As part of each semiannual compliance report required by Sec. 
63.4311, you must identify any web coating/printing operation or dyeing/
finishing operation for which you used the emission rate without add-on 
controls option. If there were no deviations from the applicable 
emission limit in Table 1 to this subpart, you must submit a statement 
that, as appropriate, the web coating/printing operations or the dyeing/
finishing operations were in compliance with the emission limitations 
during the reporting period because the organic HAP emission rate for 
each compliance period was less than or equal to the applicable emission 
limit in Table 1 to this subpart.
    (d) You must maintain records as specified in Sec. Sec. 63.4312 and 
63.4313.

   Compliance Requirements for the Emission Rate With Add-On Controls 
                                 Option



Sec. 63.4340  By what date must I conduct performance tests and other
initial compliance demonstrations?

    (a) New and reconstructed affected sources. For a new or 
reconstructed affected source, you must meet the requirements of 
paragraphs (a)(1) through (4) of this section.
    (1) All emission capture systems, add-on control devices, and CPMS 
must be installed and operating no later than the applicable compliance

emission capture system and add-on control device required by Sec. 
63.4292 until after you have completed the performance tests specified 
in paragraph (a)(1) of this section. Instead, you must maintain a log 
detailing the operation and maintenance of the emission capture system, 
add-on control device, and continuous parameter monitors during the 
period between the compliance date and the performance test. You must 
begin complying with the operating limits for your affected source on 
the date you complete the performance tests specified in paragraph

Sec. 63.4341(e)(5) or (f)(5).
    (b) Existing sources. For an existing affected source, you must meet 
the requirements of paragraphs (b)(1) through (3) of this section.
    (1) All emission capture systems, add-on control devices, and CPMS 
must be installed and operating no later than the applicable compliance 
date specified in Sec. 63.4283. Except for solvent recovery systems for 
which you conduct liquid-liquid material balances according to Sec.

Sec. 63.4341  How do I demonstrate initial compliance?

    (a) You may use the emission rate with add-on controls option for 
any individual web coating/printing operation, for any group of web 
coating/printing operations in the affected source, or for all of the 
web coating/printing operations in the affected source. You may include 
both controlled and uncontrolled web coating/printing operations in a 
group for which you use this option. You must use either the compliant 
material option, the emission rate without add-on controls option, the 
organic HAP overall control efficiency option, or the oxidizer outlet 
organic HAP concentration option for any web coating/printing operation 
in the affected source for which you do not use the emission rate with 
add-on controls option. To demonstrate initial compliance, any web 
coating/printing operation for which you use the emission rate with add-
on controls option must meet the applicable emission limitations in 
Table 1 to this subpart, and in Sec. Sec. 63.4292 and 63.4293. You must 
meet all the requirements of paragraphs (a), (c), (d), and (e) of this 
section. When calculating the organic HAP emission rate according to 
this section, do not include any coating, printing, thinning, or 
cleaning materials applied on web coating/printing operations for which 
you use the compliant material option, the emission rate without add-on 
controls option, the organic HAP overall control efficiency option, or 
the oxidizer outlet organic HAP concentration option. You do not need to 
redetermine the mass of organic HAP in coating, printing, thinning, or 
cleaning materials that have been reclaimed onsite and reused in the web 
coating/printing operation(s) for which you use the emission rate with 
add-on control option.
    (b) You may use the emission rate with add-on controls option for 
any individual dyeing/finishing operation, for any group of dyeing/
finishing operations in the affected source, or for all of the dyeing/
finishing operations in the affected source. You may include

[[Page 683]]

both controlled and uncontrolled dyeing/finishing operations in a group 
for which you use this option. You must use either the compliant 
material option or the emission rate without add-on controls option for 
any dyeing/finishing operation in the affected source for which you do 
not use the emission rate with add-on controls option. You may not use 
the emission rate with add-on controls option for any dyeing/finishing 
operation in a dyeing/finishing affected source for which you use the 
equivalent emission rate option. To demonstrate initial compliance, any 
dyeing/finishing operation for which you use the emission rate with add-
on controls option must meet the applicable emission limitations in 
Table 1 to this subpart, and in Sec. Sec. 63.4292 and 63.4293. You must 
meet all the requirements of paragraphs (b), (c), (d), and (f) this 
section. When calculating the organic HAP emission rate according to 
this section, do not include any dyeing or finishing materials applied 
on dyeing/finishing operations for which you use the compliant material 
option or the emission rate without add-on controls option. You do not 
need to redetermine the mass of organic HAP in dyeing or finishing 
materials that have been reclaimed onsite and reused in the dyeing/
finishing operation(s) for which you use the emission rate with add-on 
controls option.
    (c) Compliance with operating limits. Except as provided in Sec. 
63.4340(a)(4), and except for solvent recovery systems for which you 
conduct liquid-liquid material balances according to Sec. 63.4341(e)(5) 
or (f)(5), you must establish and demonstrate continuous compliance 
during the initial compliance period with the operating limits required 
by Sec. 63.4292, using the procedures specified in Sec. Sec. 63.4363 
and 63.4364.
    (d) Compliance with work practice requirements. You must develop, 
implement, and document your implementation of the work practice plan 
required by Sec. 63.4293 during the initial compliance period as 
specified in Sec. 63.4312.
    (e) Compliance with web coating/printing emission limits. You must 
follow the procedures in paragraphs (e)(1) through (8) of this section 
to demonstrate compliance with the applicable web coating/printing 
emission limit in Table 1 to this subpart.
    (1) Determine the mass fraction of organic HAP, the mass fraction of 
solids, and mass of materials. Follow the procedures specified in Sec. 
63.4331(a)(1), (2), and (3) to determine the mass fraction of organic 
HAP for each coating, printing, thinning, and cleaning material applied 
during the compliance period; the mass fraction of solids for each 
coating and printing material applied during the compliance period; and 
mass of each coating, printing, thinning, and cleaning material applied 
during the compliance period.
    (2) Calculate the mass of organic HAP emissions before add-on 
controls. Using Equation 1 of Sec. 63.4331, calculate the mass of 
organic HAP emissions before add-on controls from all coating, printing, 
thinning, and cleaning materials applied during the compliance period 
minus the organic HAP in certain waste materials in the web coating/
printing operation or group of web coating/printing operations for which 
you use the emission rate with add-on controls.
    (3) Calculate the organic HAP emissions reductions for each 
controlled web coating/printing operation. Determine the mass of organic 
HAP emissions reduced for each controlled web coating/printing operation 
during the compliance period. The emissions reductions determination 
quantifies the total organic HAP emissions that pass through the 
emission capture system and are destroyed or removed by the add-on 
control device. Use the procedures in paragraph (e)(4) of this section 
to calculate the mass of organic HAP emissions reductions for each 
controlled web coating/printing operation using an emission capture 
system and add-on control device other than a solvent recovery system

material balance. For each controlled web coating/printing operation 
using an emission capture system and add-on control device other than a 
solvent recovery system for which you conduct liquid-liquid material 
balances, calculate the organic HAP emissions reductions using Equation 
1 of this section. The equation applies the emission capture system 
efficiency and add-on control device efficiency to the mass of organic 
HAP contained in the coating, printing, thinning, and cleaning materials 
applied in the web coating/printing operation served by the emission 
capture system and add-on control device during the compliance period. 
For any period of time a deviation specified in Sec. 63.4342(c) or (d) 
occurs in the controlled web coating/printing operation, including a 
deviation during startup, shutdown, or malfunction, then you must assume 
zero efficiency for the emission capture system and add-on control 
device. Equation 1 of this section treats the coating, printing, 
thinning, and cleaning materials applied during such a deviation as if 
they were used on an uncontrolled web coating/printing operation for the 
time period of the deviation.

dyeing/finishing operation not using liquid-liquid material balance. For 
each controlled dyeing/finishing operation using an emission capture 
system and add-on control device other than a solvent recovery system 
for which you conduct liquid-liquid material balances, calculate the 
organic HAP emissions reductions using Equation 5 of this section. The 
equation applies the emission capture system efficiency and add-on 
control device efficiency to the mass of organic HAP contained in the 
dyeing and finishing materials applied in the dyeing/finishing operation 
served by the emission capture system and add-on control device during 
the compliance period. For any period of time a deviation specified in 
Sec. 63.4342(c) or (d) occurs in the controlled dyeing/finishing 
operation, including a deviation during startup, shutdown, or 
malfunction, then you must assume zero efficiency for the emission 
capture system and add-on control device. Equation 5 of this section 
treats the dyeing and finishing materials applied during such a 
deviation as if they were applied on an uncontrolled dyeing/finishing 
operation for the time period of the deviation.

    (8) Compliance demonstration. To demonstrate initial compliance with 
the emission limit, the organic HAP emission rate with add-on controls 
for the compliance period, calculated using Equation 8 of this section, 
must be less than or equal to the applicable emission limit in Table 1 
to this subpart. You must keep all records as required by Sec. Sec. 
63.4312 and 63.4313. As part of the Notification of Compliance Status 
required by Sec. 63.4310, you must identify the dyeing/finishing 
operation(s) for which you used the emission rate with add-on controls 
option and submit a statement that the dyeing/finishing operation(s) was 
(were) in compliance with the emission limitations during the initial 
compliance period because the organic HAP emission rate was less than or 
equal to the applicable emission limit in Table 1 to this subpart, and 
that you achieved the operating limits required by Sec. 63.4292 and the 
work practice standards required by Sec. 63.4293.



Sec. 63.4342  How do I demonstrate continuous compliance with the
emission limitations?

    (a) To demonstrate continuous compliance with the applicable 
emission limit in Table 1 to this subpart, the organic HAP emission rate 
for each compliance period, determined according to Sec. 63.4341(e) for 
web coating/printing operations and according to Sec. 63.4341(f) for 
dyeing/finishing operations, must be equal to or less than the 
applicable emission limit in Table 1 to this subpart. Each month 
following the initial compliance period described in Sec. 63.4340 is a 
compliance period consisting of that month and the preceding 11 months. 
You must perform the calculations in Sec. 63.4341 on a monthly basis.
    (b) If the organic HAP emission rate with add-on controls for any 
compliance period exceeded the applicable emission limit in Table 1 to 
this subpart, this is a deviation from the emission limitation for that 
compliance period and must be reported as specified in Sec. Sec. 
63.4310(c)(6) and 63.4311(a)(7).
    (c) You must demonstrate continuous compliance with each operating 
limit required by Sec. 63.4292 that applies to you, as specified in 
Table 2 to this subpart.
    (1) If an operating parameter is out of the allowed range specified 
in Table 2 to this subpart, this is a deviation from the operating limit 
that must be reported as specified in Sec. Sec. 63.4310(c)(6) and 
63.4311(a)(7).
    (2) If an operating parameter deviates from the operating limit 
specified in Table 2 to this subpart, then you must assume that the 
emission capture system and add-on control device were achieving zero 
efficiency during the time period of the deviation. For the purposes of 
completing the compliance calculations specified in Sec. 63.4341 (e)(4) 
and (f)(4), you must treat the regulated materials applied during a 
deviation on a controlled coating/printing or dyeing/finishing operation 
as if they were applied on an uncontrolled coating/printing or dyeing/
finishing operation for the time period of the deviation, as indicated 
in Equation 1 of Sec. 63.4341 for a web coating/printing operation, and 
in Equation 5 of Sec. 63.4341 for a dyeing/finishing operation.
    (d) You must meet the requirements for bypass lines in Sec. 
63.4364(b) for controlled coating/printing or dyeing/finishing 
operations for which you do not conduct liquid-liquid material balances. 
If any bypass line is opened and emissions are diverted to the 
atmosphere when the web coating/printing or dyeing/finishing operation 
is running, this is a deviation that must be reported as specified in 
Sec. Sec. 63.4310(c)(6) and 63.4311(a)(7). For the purposes of 
completing the compliance calculations specified in Sec. 63.4341(e)(4), 
you must treat the coating, printing, thinning, and cleaning materials 
applied during a deviation on a controlled web coating/printing 
operation as if they were used on an uncontrolled web coating/printing 
operation for the time period

[[Page 692]]

of the deviation, as indicated in Equation 1 of Sec. 63.4341. For the 
purposes of completing the compliance calculations specified in Sec. 
63.4341(f)(4), you must treat the dyeing and finishing materials applied 
during a deviation on a controlled dyeing/finishing operation as if they 
were used on an uncontrolled dyeing/finishing operation for the time 
period of the deviation, as indicated in Equation 5 of Sec. 63.4341.
    (e) You must demonstrate continuous compliance with the work 
practice standards in Sec. 63.4293. If you did not develop a work 
practice plan, or you did not implement the plan, or you did not keep 
the records required by Sec. 63.4312(j)(8), this is a deviation from 
the work practice standards that must be reported as specified in 
Sec. Sec. 63.4310(c)(6) and 63.4311(a)(7).
    (f) As part of each semiannual compliance report required in Sec. 
63.4311, you must identify the coating/printing and dyeing/finishing 
operation(s) for which you use the emission rate with add-on controls 
option. If there were no deviations from the applicable emission limit 
in Table 1 to this subpart, you must submit a statement that, as 
appropriate, the web coating/printing operations or the dyeing/finishing 
operations were in compliance with the emission limitations during the 
reporting period because the organic HAP emission rate for each 
compliance period was less than or equal to the applicable emission 
limit in Table 1 to this subpart, and you achieved the operating limits 
required by Sec. 63.4292 and the work practice standards required by 
Sec. 63.4293 during each compliance period.
    (g) [Reserved]
    (h) Consistent with Sec. Sec. 63.6(e) and 63.7(e)(1), deviations 
that occur during a period of startup, shutdown, or malfunction of the 
emission capture system, add-on control device, or web coating/printing 
or dyeing/finishing operation that may affect emission capture or 
control device efficiency are not violations if you demonstrate to the 
Administrator's satisfaction that you were operating in accordance with 
Sec. 63.6(e)(1). The Administrator will determine whether deviations 
that occur during a period of startup, shutdown, or malfunction are 
violations according to the provisions in Sec. 63.6(e).
    (i) [Reserved]
    (j) You must maintain records as specified in Sec. Sec. 63.4312 and 
63.4313.

 Compliance Requirements for the Organic HAP Overall Control Efficiency 
          and Oxidizer Outlet Organic HAP Concentration Options



Sec. 63.4350  By what date must I conduct performance tests and other
initial compliance demonstrations?

    (a) New and reconstructed affected sources. For a new or 
reconstructed affected source, you must meet the requirements of 
paragraphs (a)(1) through (4) of this section.
    (1) All emission capture systems, add-on control devices, and CPMS 
must be installed and operating no later than the applicable compliance 
date specified in Sec. 63.4283. Except for solvent recovery systems for 
which you conduct liquid-liquid material balances according to Sec. 
63.4351(d)(5), you must conduct a performance test of each capture 
system and add-on control device according to the procedures in 
Sec. Sec. 63.4360, 63.4361, and 63.4362, and establish the operating 
limits required by Sec. 63.4292, within 180 days of the applicable 
compliance date specified in Sec. 63.4283. For a solvent recovery 
system for which you conduct liquid-liquid material balances according 
to Sec. 63.4351(d)(5), you must initiate the first material balance no 
later than the applicable compliance date specified in Sec. 63.4283.

specified in Sec. 63.4283 and ends on the last day of the first full 
month after the compliance date, or the date you conduct the performance 
tests of the emission capture systems and add-on control devices, or 
initiate the first liquid-liquid material

[[Page 693]]

balance for a solvent recovery system, whichever is later. The initial 
compliance demonstration includes the results of emission capture system 
and add-on control device performance tests conducted according to 
Sec. Sec. 63.4360, 63.4361, and 63.4362; results of liquid-liquid 
material balances conducted according to Sec. 63.4351(d)(5); 
calculations according to Sec. 63.4351 and supporting documentation 
showing that during the initial compliance period either the organic HAP 
overall control efficiency was equal to or greater than the applicable 
overall control efficiency limit in Table 1 to this subpart or the 
oxidizer outlet organic HAP concentration was no greater than 20 parts 
per million by weight (ppmw) on a dry basis; the operating limits 
established during the performance tests and the results of the 
continuous parameter monitoring required by Sec. 63.4364; and 
documentation of whether you developed and implemented the work practice 
plan required by Sec. 63.4293.
    (4) You do not need to comply with the operating limits for the 
emission capture system and add-on control device required by Sec. 
63.4292 until after you have completed the performance tests specified 
in paragraph (a)(1) of this section. Instead, you must maintain a log 
detailing the operation and maintenance of the emission capture system, 
add-on control device, and continuous parameter monitors during the 
period between the compliance date and the performance test. You must 
begin complying with the operating limits for your affected source on 
the date you complete the performance tests specified in paragraph 
(a)(1) of this section. This requirement does not apply to solvent 
recovery systems for which you conduct liquid-liquid material balances 
according to the requirements of Sec. 63.4351(d)(5).
    (b) Existing sources. For an existing affected source, you must meet 
the requirements of paragraphs (b)(1) through (3) of this section.
    (1) All emission capture systems, add-on control devices, and CPMS 
must be installed and operating no later than the applicable compliance 
date specified in Sec. 63.4283. Except for solvent recovery systems for 
which you conduct liquid-liquid material balances according to Sec. 
63.4351(d)(5), you must conduct a performance test of each capture 
system and add-on control device according to the procedures in 
Sec. Sec. 63.4360, 63.4361, and 63.4362, and establish the operating 
limits required by Sec. 63.4292, within 180 days of the compliance date

Sec. 63.4283.
    (3) You must complete the compliance demonstration for the initial 
compliance period according to the requirements of Sec. 63.4351. The 
initial compliance period begins on the applicable compliance date 
specified in Sec. 63.4283 and ends on the last day of the first full 
month after the compliance date. The initial compliance demonstration 
includes the results of emission capture system and add-on control 
device performance tests conducted according to Sec. Sec. 63.4360, 
63.4361, and 63.4362; results of liquid-liquid material balances 
conducted according to Sec. 63.4351(d)(5); calculations according to 
Sec. 63.4351 and supporting documentation showing that during the 
initial compliance period the organic HAP overall control efficiency was

efficiency limit in Table 1 to this subpart or the oxidizer outlet 
organic HAP concentration was no greater than 20 ppmw on a dry basis and 
the efficiency of the capture system was 100 percent; the operating 
limits established during the performance tests and the results of the 
continuous parameter monitoring required by Sec. 63.4364; and 
documentation of whether you developed and implemented the work practice 
plan required by Sec. 63.4293.



Sec. 63.4351  How do I demonstrate initial compliance?

    (a) You may use the organic HAP overall control efficiency option or 
the oxidizer outlet organic HAP concentration option for any individual 
web coating/printing operation, for any

[[Page 694]]

group of web coating/printing operations in the affected source, or for 
all of the web coating/printing operations in the affected source. You 
may include both controlled and uncontrolled web coating/printing 
operations in a group for which you use the organic HAP overall control 
efficiency option. You must use either the compliant material option, 
the emission rate without add-on controls option, or the emission rate 
with add-on controls option for any web coating/printing operation(s) in 
the affected source for which you do not use either the organic HAP 
overall control efficiency option or the oxidizer outlet organic HAP 
concentration option. To demonstrate initial compliance, any web 
coating/printing operation for which you use the organic HAP overall 
control efficiency option must meet the applicable organic HAP overall 
control efficiency limitations in Table 1 to this subpart according to 
the procedures in paragraph (d) of this section. Any web coating/
printing operation for which you use the oxidizer outlet organic HAP 
concentration option must meet the 20 ppmw on a dry basis limit and 
achieve 100 percent capture efficiencies according to the procedures in 
paragraph (e) of this section. To demonstrate initial compliance with 
either option, you also must meet the applicable operating limits in 
Sec. 63.4292 according to the procedures in paragraph (b) of this 
section and the work practice standards in Sec. 63.4293 according to 
the procedures in paragraph (c) of this section. When calculating the 
organic HAP overall control efficiency according to this section, do not 
include any coating, printing, thinning, or cleaning materials applied 
on web coating/printing operations for which you use the compliant 
material option, the emission rate without add-on controls option, the 
emission rate with add-on controls option, or the oxidizer outlet 
organic HAP concentration option. You do not need to redetermine the 
mass of organic HAP in coating, printing, thinning, or cleaning 
materials that have been reclaimed onsite and reused in web coating/
printing operation(s) for which you use the organic HAP overall control 
efficiency option.
    (b) Compliance with operating limits. Except as provided in Sec. 
63.4350(a)(4), and except for solvent recovery systems for which you 
conduct liquid-liquid material balances according to Sec. 
63.4351(d)(5), you must establish and demonstrate continuous compliance 
during the initial compliance period with the operating limits required 
by Sec. 63.4292, using the procedures specified in Sec. Sec. 63.4363 
and 63.4364.
    (c) Compliance with work practice requirements. You must develop, 
implement, and document your implementation of the work practice plan 
required by Sec. 63.4293 during the initial compliance period as 
specified in Sec. 63.4312.
    (d) Compliance with organic HAP overall control efficiency limits. 
You must follow the procedures in paragraphs (d)(1) through (7) of this 
section to demonstrate compliance with the applicable organic HAP 
overall control efficiency limit in Table 1 to this subpart.
    (1) Determine the mass fraction of organic HAP and mass of coating 
or printing materials. Follow the procedures specified in Sec. 
63.4331(a)(1) and (3) to determine the mass fraction of organic HAP and 
mass of each coating, printing, thinning, and cleaning material applied 
during the compliance period.
    (2) Calculate the total mass of organic HAP emissions before add-on 
controls. Using Equation 1 of Sec. 63.4331, calculate the total mass of 
organic HAP emissions before add-on controls from all coating, printing, 
thinning, and cleaning materials applied during the compliance period 
minus the organic HAP in certain waste materials in the web coating/
printing operation or group of web coating/printing operations for which 
you use the organic HAP overall control efficiency option.
    (3) Calculate the organic HAP emissions reductions for each 
controlled web coating/printing operation. Determine the mass of organic 
HAP emissions reduced for each controlled web coating/printing operation 
during the compliance period. The emissions reductions determination 
quantifies the total organic HAP emissions that pass through the 
emission capture system and are destroyed or removed by the add-on 
control device. Use the procedures in paragraph (d)(4) of this section 
to calculate

[[Page 695]]

the mass of organic HAP emissions reductions for each controlled web 
coating/printing operation using an emission capture system and add-on 
control device other than a solvent recovery system for which you 
conduct liquid-liquid material balances. For each controlled web 
coating/printing operation using a solvent recovery system for which you 
conduct a liquid-liquid material balance, use the procedures in 
paragraph (d)(5) of this section to calculate the organic HAP emissions 
reductions.
    (4) Calculate the organic HAP emissions reductions for controlled 
web coating/printing operations not using liquid-liquid material 
balance. For each controlled web coating/printing operation using an 
emission capture system and add-on control device other than a solvent 
recovery system for which you conduct liquid-liquid material balances, 
calculate the organic HAP emissions reductions using Equation 1 of Sec. 
63.4341. The equation applies the emission capture system efficiency and 
add-on control device efficiency to the mass of organic HAP contained in 
the coating, printing, thinning, and cleaning materials applied in the 
web coating/printing operation served by the emission capture system and 
add-on control device during the compliance period. For any period of 
time a deviation specified in Sec. 63.4352(c) or (d) occurs in the 
controlled web coating/printing operation, including a deviation during 
startup, shutdown, or malfunction, then you must assume zero efficiency 
for the emission capture system and add-on control device. Equation 1 of 
Sec. 63.4341 treats the coating, printing, thinning, and cleaning 
materials applied during such a deviation as if they were applied on an 
uncontrolled web coating/printing operation for the time period of the 
deviation.
    (i) Calculate the total mass of organic HAP in the coating and 
printing material(s) applied in the controlled web coating/printing 
operation during the compliance period, kg, using Equation 1A of Sec. 
63.4341.
    (ii) Calculate the total mass of organic HAP in the thinning and 
cleaning materials applied in the controlled web coating/printing 
operation(s) during the compliance period, kg, using Equation 1B of 
Sec. 63.4341.
    (iii) Calculate the mass of organic HAP in the coating, printing, 
thinning, and cleaning materials applied in the controlled web coating/
printing operation during deviations specified in Sec. 63.4352(c) and 
(d), using Equation 1C of Sec. 63.4341.
    (5) Calculate the organic HAP emissions reductions for controlled 
web coating/printing operations using liquid-liquid material balance. 
For each controlled web coating/printing operation using a solvent 
recovery system for which you conduct liquid-liquid material balances, 
calculate the organic HAP emissions reductions by applying the volatile 
organic matter collection and recovery efficiency to the mass of organic 
HAP contained in the coating, printing, thinning, and cleaning materials 
applied in the web coating/printing operation controlled by the solvent 
recovery system during the compliance period. Perform a liquid-liquid 
material balance for the compliance period as specified in paragraphs 
(d)(5)(i) through (vi) of this section.
    (i) For each solvent recovery system, install, calibrate, maintain, 
and operate according to the manufacturer's specifications, a device 
that indicates the cumulative amount of volatile organic matter 
recovered by the solvent recovery system for the compliance period. The 
device must be initially certified by the manufacturer to be accurate to 
within 2.0 percent of the mass of volatile organic 
matter recovered.
    (ii) For each solvent recovery system, determine the mass of 
volatile organic matter recovered for the compliance period, kg, based 
on measurement with the device required in paragraph (d)(5)(i) of this 
section.
    (iii) Determine the mass fraction of volatile organic matter for 
each coating and printing material applied in the web coating/printing 
operation controlled by the solvent recovery system during the 
compliance period, kg volatile organic matter per kg coating and 
printing material. You may determine the volatile organic matter mass 
fraction using Method 24 of 40 CFR part 60, appendix A, or an EPA 
approved alternative method, or you may use information provided by the 
manufacturer

[[Page 696]]

or supplier of the coating or printing material. In the event of any 
inconsistency between information provided by the manufacturer or 
supplier and the results of Method 24 of 40 CFR part 60, appendix A, or 
an approved alternative method, the test method results will govern.
    (iv) Measure the mass of each coating, printing, thinning, and 
cleaning material applied in the web coating/printing operation 
controlled by the solvent recovery system during the compliance period, 
kg.
    (v) For the compliance period, calculate the solvent recovery 
system's volatile organic matter collection and recovery efficiency 
using Equation 2 of Sec. 63.4341.
    (vi) Calculate the mass of organic HAP emissions reductions for the 
web coating/printing operation controlled by the solvent recovery system 
during the compliance period, using Equation 3 of Sec. 63.4341.
    (6) Calculate the organic HAP overall control efficiency. Determine 
the organic HAP overall control efficiency, kg organic HAP emissions 
reductions per kg organic HAP emissions before add-on controls during 
the compliance period, using Equation 1 of this section.

    (7) Compliance demonstration. To demonstrate initial compliance with 
the organic HAP overall control efficiency in Table 1 to this subpart, 
the organic HAP overall control efficiency calculated using Equation 1 
of this section must be at least 98 percent for new or reconstructed 
affected sources and at least 97 percent for existing affected sources. 
You must keep all records as required by Sec. Sec. 63.4312 and 63.4313. 
As part of the Notification of Compliance Status required by Sec. 
63.4310, you must identify the web coating/printing operation(s) for 
which you used the organic HAP overall control efficiency option and 
submit a statement that the web coating/printing operation(s) was (were) 
in compliance with the emission limitations during the initial 
compliance period because the organic HAP overall control efficiency was 
greater than or equal to the applicable organic HAP overall control 
efficiency in Table 1 to this subpart, and you achieved the operating 
limits required by Sec. 63.4292 and the work practice standards 
required by Sec. 63.4293.
    (e) Compliance with oxidizer outlet organic HAP concentration limit. 
You must follow the procedures in paragraphs (e)(1) through (3) of this 
section to demonstrate compliance with the oxidizer outlet organic HAP 
concentration limit of no greater than 20 ppmw on a dry basis.
    (1) Install and operate a PTE. Install and operate a PTE around each 
work station and associated drying or curing

[[Page 697]]

oven in the web coating/printing operation. An enclosure that meets the 
requirements in Sec. 63.4361(a) is considered a PTE. Route all organic 
HAP emissions from each PTE to an oxidizer.
    (2) Determine oxidizer outlet organic HAP concentration. Determine 
oxidizer outlet organic HAP concentration through performance tests 
using the procedures in Sec. 63.4362(a) and (b).
    (3) Compliance demonstration. To demonstrate initial compliance with 
the oxidizer outlet organic HAP concentration limit in Table 1 to this 
subpart, the oxidizer outlet organic HAP concentration must be no 
greater than 20 ppmv on a dry basis and the efficiency of the capture 
system must be 100 percent. You must keep all records as required by 
Sec. Sec. 63.4312 and 63.4313. As part of the Notification of 
Compliance Status required by Sec. 63.4310, you must identify the web 
coating/printing operation(s) for which you used the oxidizer outlet 
organic HAP concentration option and submit a statement that the web 
coating/printing operation(s) was (were) in compliance with the emission 
limitations during the initial compliance period because the oxidizer 
outlet organic HAP concentration was no greater than 20 ppmv on a dry 
basis, the efficiency of the capture system was 100 percent, and you 
achieved the operating limits required by Sec. 63.4292 and the work 
practice standards required by Sec. 63.4293.



Sec. 63.4352  How do I demonstrate continuous compliance with the
emission limitations?

    (a) You must meet all the requirements of this section to 
demonstrate continuous compliance with the organic HAP overall control 
efficiency. The organic HAP overall control efficiency for each 
compliance period, determined according to the procedures in Sec. 
63.4351(d), must be equal to or greater than the applicable organic HAP 
overall control efficiency limit in Table 1 to this subpart. Each month 
following the initial compliance period described in Sec. 63.4350 is a 
compliance period. You must perform the calculations in Sec. 63.4351(d) 
on a monthly basis. You must meet the applicable requirements of 
paragraphs (c) through (j) of this section to demonstrate continuous 
compliance with the oxidizer outlet organic HAP concentration limit.
    (b) If the organic HAP overall control efficiency for any compliance 
period failed to meet the applicable organic HAP overall control 
efficiency in Table 1 to this subpart, this is a deviation from the 
emission limitation for that compliance period and must be reported as 
specified in Sec. Sec. 63.4310(c)(6) and 63.4311(a)(7).
    (c) You must demonstrate continuous compliance with each operating 
limit required by Sec. 63.4292 that applies to you, as specified in 
Table 2 to this subpart.
    (1) If an operating parameter is out of the allowed range specified 
in Table 2 to this subpart, this is a deviation from the operating limit 
that must be reported as specified in Sec. Sec. 63.4310(c)(6) and 
63.4311(a)(7).
    (2) If an operating parameter deviates from the operating limit 
specified in Table 2 to this subpart, then you must assume that the 
emission capture system and add-on control device were achieving zero 
efficiency during the time period of the deviation. For the purposes of 
completing the compliance calculations specified in Sec. 63.4351(d)(4), 
you must treat the coating, printing, thinning, and cleaning materials 
applied during a deviation on a controlled web coating/printing 
operation as if they were applied on an uncontrolled web coating/
printing operation for the time period of the deviation as indicated in 
Equation 1 of Sec. 63.4341.
    (d) You must meet the requirements for bypass lines in Sec. 
63.4364(b) for controlled web coating/printing operations for which you 
do not conduct liquid-liquid material balances. If any bypass line is 
opened and emissions are diverted to the atmosphere when the web 
coating/printing operation is running, this is a deviation that must be 
reported as specified in Sec. Sec. 63.4310(c)(6) and 63.4311(a)(7). For 
the purposes of completing the compliance calculations specified in 
Sec. 63.4351(d)(4), you must treat the coating, printing, thinning, and 
cleaning materials applied during a deviation on a controlled web 
coating/printing operation as if they were applied on an uncontrolled 
web coating/printing operation for the time period of the deviation as 
indicated in Equation 1 of Sec. 63.4341.

[[Page 698]]

    (e) You must demonstrate continuous compliance with the work 
practice standards in Sec. 63.4293. If you did not develop a work 
practice plan, or you did not implement the plan, or you did not keep 
the records required by Sec. 63.4312(j)(8), this is a deviation from 
the work practice standards that must be reported as specified in 
Sec. Sec. 63.4310(c)(6) and 63.4311(a)(7).
    (f) As part of each semiannual compliance report required in Sec. 
63.4311, you must identify the web coating/printing operation(s) for 
which you use the organic HAP overall control efficiency option or the 
oxidizer outlet organic HAP concentration option. If there were no 
deviations from the organic HAP overall control efficiency limitations, 
submit a statement that you were in compliance with the emission 
limitations during the reporting period because the organic HAP overall 
control efficiency for each compliance period was greater than or equal 
to the applicable organic HAP overall control efficiency in Table 1 to 
this subpart, and you achieved the operating limits required by Sec. 
63.4292 and the work practice standards required by Sec. 63.4293 during 
each compliance period. If there were no deviations from the oxidizer 
outlet organic HAP concentration limit, submit a statement that you were 
in compliance with the oxidizer outlet organic HAP concentration limit, 
the efficiency of the capture system is 100 percent, and you achieved 
the operating limits required by Sec. 63.4292 and the work practice 
standards required by Sec. 63.4293 during each compliance period.
    (g) [Reserved]
    (h) Consistent with Sec. Sec. 63.6(e) and 63.7(e)(1), deviations 
that occur during a period of startup, shutdown, or malfunction of the 
emission capture system, add-on control device, or web coating/printing 
operation that may affect emission capture or control device efficiency 
are not violations if you demonstrate to the Administrator's 
satisfaction that you were operating in accordance with Sec. 
63.6(e)(1). The Administrator will determine whether deviations that 
occur during a period of startup, shutdown, or malfunction are 
violations according to the provisions in Sec. 63.6(e).
    (i) [Reserved]
    (j) You must maintain records as specified in Sec. Sec. 63.4312 and 
63.4313.

             Performance Testing and Monitoring Requirements



Sec. 63.4360  What are the general requirements for performance tests?

    (a) You must conduct each performance test required by Sec. Sec. 
63.4340 or 63.4350 according to the requirements in Sec. 63.7(e)(1) and 
under the conditions in this section, unless you obtain a waiver of the 
performance test according to the provisions in Sec. 63.7(h).
    (1) Representative web coating/printing or dyeing/finishing 
operation operating conditions. You must conduct the performance test 
under representative operating conditions for the web coating/printing 
or dyeing/finishing operation. Operations during periods of startup, 
shutdown, or malfunction and during periods of nonoperation do not 
constitute representative conditions. You must record the process 
information that is necessary to document operating conditions during 
the test and explain why the conditions represent normal operation.
    (2) Representative emission capture system and add-on control device 
operating conditions. You must conduct the performance test when the 
emission capture system and add-on control device are operating at a 
representative flow rate, and the add-on control device is operating at 
a representative inlet concentration. You must record information that 
is necessary to document emission capture system and add-on control 
device operating conditions during the test and explain why the 
conditions represent normal operation.
    (b) You must conduct each performance test of an emission capture 
system according to the requirements in Sec. 63.4361. You must conduct 
each performance test of an add-on control device according to the 
requirements in Sec. 63.4362.



Sec. 63.4361  How do I determine the emission capture system efficiency?

    You must use the procedures and test methods in this section to 
determine

[[Page 699]]

capture efficiency as part of the performance test required by 
Sec. Sec. 63.4340 or 63.4350.
    (a) Assuming 100 percent capture efficiency. You may assume the 
capture system efficiency is 100 percent if both of the conditions in 
paragraphs (a)(1) and (2) of this section are met.
    (1) The capture system meets the criteria in Method 204 of appendix 
M to 40 CFR part 51 for a PTE and directs all the exhaust gases from the 
enclosure to an add-on control device.
    (2) All regulated materials applied in the web coating/printing or 
dyeing/finishing operation are applied within the capture system; 
regulated material solvent flash-off, curing, and drying occurs within 
the capture system; and the removal or evaporation of cleaning materials 
from the web coating/printing operation surfaces they are applied to 
occurs within the capture system. For example, this criterion is not met 
if the web enters the open shop environment when moving between the 
application station and a curing oven.
    (b) Measuring capture efficiency. If the capture system does not 
meet both of the criteria in paragraphs (a)(1) and (2) of this section, 
then you must use one of the three protocols described in paragraphs 
(c), (d), and (e) of this section to measure capture efficiency. The 
capture efficiency measurements use TVH capture efficiency as a 
surrogate for organic HAP capture efficiency. For the protocols in 
paragraphs (c) and (d) of this section, the capture efficiency 
measurement must consist of three test runs. Each test run must be at 
least 3 hours duration or the length of a production run, up to 8 hours.
    (c) Liquid-to-uncaptured-gas protocol using a temporary total 
enclosure or building enclosure. The liquid-to-uncaptured-gas protocol 
compares the mass of liquid TVH in regulated materials applied in the 
web coating/printing or dyeing/finishing operation to the mass of TVH 
emissions not captured by the emission capture system. Use a temporary 
total enclosure or a building enclosure and the procedures in paragraphs 
(c)(1) through (6) of this section to measure emission capture system 
efficiency using the liquid-to-uncaptured-gas protocol.
    (1) Either use a building enclosure or construct an enclosure around 
the web coating/printing or dyeing/finishing operation where regulated 
materials are applied, and all areas where emissions from these applied 
regulated materials subsequently occur, such as flash-off, curing, and 
drying areas. The areas of the web coating/printing or dyeing/finishing 
operation where capture devices collect emissions for routing to an add-
on control device, such as the entrance and exit areas of an oven or 
tenter frame, must also be inside the enclosure. The enclosure must meet 
the applicable definition of a temporary total enclosure or building 
enclosure in Method 204 of appendix M to 40 CFR part 51.
    (2) Use Method 204A or 204F of appendix M to 40 CFR part 51 to 
determine the mass fraction of TVH liquid input from each regulated 
material used in the web coating/printing or dyeing/finishing operation 
during each capture efficiency test run. To make the determination, 
substitute TVH for each occurrence of the term volatile organic 
compounds (VOC) in the methods.
    (3) Use Equation 1 of this section to calculate the total mass of 
TVH liquid input from all the regulated materials applied in the web 
coating/printing or dyeing/finishing operation during each capture 
efficiency test run.
[GRAPHIC] [TIFF OMITTED] TR29MY03.028

Where:

TVHapplied = Mass of liquid TVH in regulated materials 
          applied in the web coating/printing or dyeing/finishing 
          operation during the capture efficiency test run, kg.
TVHi = Mass fraction of TVH in regulated material, i, that is 
          applied in the web

[[Page 700]]

          coating/printing or dyeing/finishing operation during the 
          capture efficiency test run, kg TVH per kg material.
Mi = Total mass of regulated material, i, applied in the web 
          coating/printing or dyeing/finishing operation during the 
          capture efficiency test run, kg.
n = Number of different regulated materials applied in the web coating/
          printing or dyeing/finishing operation during the capture 
          efficiency test run.

    (4) Use Method 204D or E of appendix M to 40 CFR part 51 to measure 
the total mass, kg, of TVH emissions that are not captured by the 
emission capture system; they are measured as they exit the temporary 
total enclosure or building enclosure during each capture efficiency 
test run. To make the measurement, substitute TVH for each occurrence of 
the term VOC in the methods.
    (i) Use Method 204D if the enclosure is a temporary total enclosure.
    (ii) Use Method 204E if the enclosure is a building enclosure. 
During the capture efficiency measurement, all organic compound-emitting 
operations inside the building enclosure, other than the web coating/
printing or dyeing/finishing operation for which capture efficiency is 
being determined, must be shut down, but all fans and blowers must be 
operating normally.
    (5) For each capture efficiency test run, determine the percent 
capture efficiency of the emission capture system using Equation 2 of 
this section:
[GRAPHIC] [TIFF OMITTED] TR29MY03.029

Where:

CE = Capture efficiency of the emission capture system vented to the 
          add-on control device, percent.
TVHapplied = Total mass of TVH liquid input applied in the 
          web coating/printing or dyeing/finishing operation during the 
          capture efficiency test run, kg.
TVHuncaptured = Total mass of TVH that is not captured by the 
          emission capture system and that exits from the temporary 
          total enclosure or building enclosure during the capture 
          efficiency test run, kg.

    (6) Determine the capture efficiency of the emission capture system 
as the average of the capture efficiencies measured in the three test 
runs.
    (d) Gas-to-gas protocol using a temporary total enclosure or a 
building enclosure. The gas-to-gas protocol compares the mass of TVH 
emissions captured by the emission capture system to the mass of TVH 
emissions not captured. Use a temporary total enclosure or a building 
enclosure and the procedures in paragraphs (d)(1) through (5) of this 
section to measure emission capture system efficiency using the gas-to-
gas protocol.
    (1) Either use a building enclosure or construct an enclosure around 
the web coating/printing or dyeing/finishing operation where regulated 
materials are applied, and all areas where emissions from these applied 
regulated materials subsequently occur, such as flash-off, curing, and 
drying areas. The areas of the web coating/printing or dyeing/finishing 
operation where capture devices collect emissions generated by the web 
coating/printing or dyeing/finishing operation for routing to an add-on 
control device, such as the entrance and exit areas of an oven or a 
tenter frame, must also be inside the enclosure. The enclosure must meet 
the applicable definition of a temporary total enclosure or building 
enclosure in Method 204 of appendix M to 40 CFR part 51.
    (2) Use Method 204B or 204C of appendix M to 40 CFR part 51 to 
measure the total mass, kg, of TVH emissions captured by the emission 
capture system during each capture efficiency test run as measured at 
the inlet to the add-on control device. To make the measurement, 
substitute TVH for each occurrence of the term VOC in the methods.
    (i) The sampling points for the Method 204B or 204C measurement must 
be upstream from the add-on control device and must represent total 
emissions routed from the capture system and entering the add-on control 
device.

[[Page 701]]

    (ii) If multiple emission streams from the capture system enter the 
add-on control device without a single common duct, then the emissions 
entering the add-on control device must be simultaneously measured in 
each duct and the total emissions entering the add-on control device 
must be determined.
    (3) Use Method 204D or 204E of appendix M to 40 CFR part 51 to 
measure the total mass, kg, of TVH emissions that are not captured by 
the emission capture system; they are measured as they exit the 
temporary total enclosure or building enclosure during each capture 
efficiency test run. To make the measurement, substitute TVH for each 
occurrence of the term VOC in the methods.
    (i) Use Method 204D if the enclosure is a temporary total enclosure.
    (ii) Use Method 204E if the enclosure is a building enclosure. 
During the capture efficiency measurement, all organic compound-emitting 
operations inside the building enclosure, other than the web coating/
printing or dyeing/finishing operation for which capture efficiency is 
being determined, must be shut down, but all fans and blowers must be 
operating normally.
    (4) For each capture efficiency test run, determine the percent 
capture efficiency of the emission capture system using Equation 3 of 
this section:
[GRAPHIC] [TIFF OMITTED] TR29MY03.030

Where:

CE = Capture efficiency of the emission capture system vented to the 
          add-on control device, percent.
TVHcaptured = Total mass of TVH captured by the emission 
          capture system as measured at the inlet to the add-on control 
          device during the emission capture efficiency test run, kg.
TVHuncaptured = Total mass of TVH that is not captured by the 
          emission capture system and that exits from the temporary 
          total enclosure or building enclosure during the capture 
          efficiency test run, kg.

    (5) Determine the capture efficiency of the emission capture system 
as the average of the capture efficiencies measured in the three test 
runs.
    (e) Alternative capture efficiency protocol. As an alternative to 
the procedures specified in paragraphs (c) and (d) of this section, you 
may determine capture efficiency using any other capture efficiency 
protocol and test methods that satisfy the criteria of either the DQO or 
LCL approach as described in appendix A to subpart KK of this part.



Sec. 63.4362  How do I determine the add-on control device emission
destruction or removal efficiency?

    You must use the procedures and test methods in this section to 
determine the add-on control device emission destruction or removal 
efficiency as part of the performance test required by Sec. Sec. 
63.4340 and 63.4350. You must conduct three test runs as specified in 
Sec. 63.7(e)(3) and each test run must last at least 1 hour.
    (a) For all types of add-on control devices, use the test methods as 
specified in paragraphs (a)(1) through (5) of this section.
    (1) Use Method 1 or 1A of appendix A to 40 CFR part 60, as 
appropriate, to select sampling sites and velocity traverse points.
    (2) Use Method 2, 2A, 2C, 2D, 2F, or 2G of appendix A to 40 CFR part 
60, as appropriate, to measure gas volumetric flow rate.
    (3) Use Method 3, 3A, or 3B of appendix A to 40 CFR part 60, as 
appropriate, for gas analysis to determine dry molecular weight. You may 
also use as an alternative to Method 3B, the manual method for measuring 
the oxygen, carbon dioxide, and carbon monoxide content of exhaust gas 
in ANSI/ASME, PTC 19.10-1981, ``Flue and Exhaust Gas Analyses [Part 10, 
Instruments and Apparatus]'' (incorporated by reference, see Sec. 
63.14).

[[Page 702]]

    (4) Use Method 4 of appendix A to 40 CFR part 60 to determine stack 
gas moisture.
    (5) Methods for determining gas volumetric flow rate, dry molecular 
weight, and stack gas moisture must be performed, as applicable, during 
each test run.
    (b) Measure the volatile organic matter concentration as carbon at 
the inlet and outlet of the add-on control device simultaneously, using 
Method 25 or 25A of appendix A to 40 CFR part 60. If you are 
demonstrating compliance with the oxidizer outlet organic HAP 
concentration limit, only the outlet volatile organic matter 
concentration must be determined. The outlet volatile organic matter 
concentration is determined as the average of the three test runs.
    (1) Use Method 25 if the add-on control device is an oxidizer and 
you expect the total gaseous organic concentration as carbon to be more 
than 50 parts per million (ppm) at the control device outlet.
    (2) Use Method 25A if the add-on control device is an oxidizer and 
you expect the total gaseous organic concentration as carbon to be 50 
ppm or less at the control device outlet. Method 25A must be used to 
demonstrate compliance with the oxidizer outlet organic HAP 
concentration limit.
    (3) Use Method 25A if the add-on control device is not an oxidizer.
    (c) If two or more add-on control devices are used for the same 
emission stream, then you must measure emissions at the outlet to the 
atmosphere of each device. For example, if one add-on control device is 
a concentrator with an outlet to the atmosphere for the high-volume, 
dilute stream that has been treated by the concentrator, and a second 
add-on control device is an oxidizer with an outlet to the atmosphere 
for the low-volume, concentrated stream that is treated with the 
oxidizer, you must measure emissions at the outlet of the oxidizer and 
the high volume dilute stream outlet of the concentrator.
    (d) For each test run, determine the total gaseous organic emissions 
mass flow rates for the inlet and the outlet of the add-on control 
device, using Equation 1 of this section. If there is more than one 
inlet or outlet to the add-on control device, you must calculate the 
total gaseous organic mass flow rate using Equation 1 of this section 
for each inlet and each outlet and then total all of the inlet emissions 
and total all of the outlet emissions:
[GRAPHIC] [TIFF OMITTED] TR29MY03.031

Where:

Mf = Total gaseous organic emissions mass flow rate, kg/hour 
          (h).
Cc = Concentration of organic compounds as carbon in the vent 
          gas, as determined by Method 25 or Method 25A, ppmv, dry 
          basis.
Qsd = Volumetric flow rate of gases entering or exiting the 
          add-on control device, as determined by Method 2, 2A, 2C, 2D, 
          2F, or 2G, dry standard cubic meters/hour (dscm/h).
0.0416 = Conversion factor for molar volume, kg-moles per cubic meter 
          (mole/m\3\) (@ 293 Kelvin (K) and 760 millimeters of mercury 
          (mmHg)).

    (e) For each test run, determine the add-on control device organic 
emissions destruction or removal efficiency using Equation 2 of this 
section.
[GRAPHIC] [TIFF OMITTED] TR29MY03.032

Where:

DRE = Organic emissions destruction or removal efficiency of the add-on 
          control device, percent.
Mfi = Total gaseous organic emissions mass flow rate at the 
          inlet(s) to the add-on control device, using Equation 1 of 
          this section, kg/h.
Mfo = Total gaseous organic emissions mass flow rate at the 
          outlet(s) of the add-on control device, using Equation 1 of 
          this section, kg/h.

    (f) Determine the emission destruction or removal efficiency of the 
add-on control device as the average of the efficiencies determined in 
the three

[[Page 703]]

test runs and calculated in Equation 2 of this section.



Sec. 63.4363  How do I establish the add-on control device operating
limits during the performance test?

    During the performance test required by Sec. Sec. 63.4340 or 
63.4350 and described in Sec. Sec. 63.4360, 63.4361, and 63.4362, you 
must establish the operating limits required by Sec. 63.4292 according 
to this section, unless you have received approval for alternative 
monitoring and operating limits under Sec. 63.8(f) as specified in 
Sec. 63.4292.
    (a) Thermal oxidizers. If your add-on control device is a thermal 
oxidizer, establish the operating limits according to paragraphs (a)(1) 
and (2) of this section.
    (1) During the performance test, you must monitor and record the 
temperature at least once every 15 minutes during each of the three test 
runs. You must monitor the temperature in the firebox of the thermal 
oxidizer or immediately downstream of the firebox before any substantial 
heat exchange occurs.
    (2) Use the data collected during the performance test to calculate 
and record the average temperature maintained during the performance 
test. This average temperature is the minimum operating limit for your 
thermal oxidizer.
    (b) Catalytic oxidizers. If your add-on control device is a 
catalytic oxidizer, establish the operating limits according to either 
paragraphs (b)(1) and (2) or paragraphs (b)(3) and (4) of this section.
    (1) During the performance test, you must monitor and record the 
temperature at the inlet to the catalyst bed and the temperature 
difference across the catalyst bed at least once every 15 minutes during 
each of the three test runs.
    (2) Use the data collected during the performance test to calculate 
and record the average temperature at the inlet to the catalyst bed and 
the average temperature difference across the catalyst bed maintained 
during the performance test. These are the minimum operating limits for 
your catalytic oxidizer.
    (3) As an alternative to monitoring the temperature difference 
across the catalyst bed, you may monitor the temperature at the inlet to 
the catalyst bed and implement a site-specific inspection and 
maintenance plan for your catalytic oxidizer as specified in paragraph 
(b)(4) of this section. During the performance test, you must monitor 
and record the temperature just before the catalyst bed at least once 
every 15 minutes during each of the three test runs. Use the data 
collected during the performance test to calculate and record the 
average temperature just before the catalyst bed during the performance 
test. This is the minimum operating limit for your catalytic oxidizer.
    (4) You must develop and implement an inspection and maintenance 
plan for your catalytic oxidizer(s) for which you elect to monitor 
according to paragraph (b)(3) of this section. The plan must address, at 
a minimum, the elements specified in paragraphs (b)(4)(i) through (iii) 
of this section.
    (i) Annual sampling and analysis of the catalyst activity (i.e., 
conversion efficiency) following the manufacturer's or catalyst 
supplier's recommended procedures.
    (ii) Monthly inspection of the oxidizer system, including the burner 
assembly and fuel supply lines for problems and, as necessary, adjust 
the equipment to assure proper air-to-fuel mixtures.
    (iii) Annual internal and monthly external visual inspection of the 
catalyst bed to check for channeling, abrasion, and settling. If 
problems are found, you must take corrective action consistent with the 
manufacturer's recommendations and conduct a new performance test to 
determine destruction efficiency according to Sec. 63.4362.



Sec. 63.4364  What are the requirements for CPMS installation, 
operation, and maintenance?

    (a) General. If you are using a control device to comply with the 
emission standards in Sec. 63.4290, you must install, operate, and 
maintain each CPMS specified in paragraphs (c) and (d) and (e) of this 
section according to the requirements in paragraphs (a)(1) through (8) 
of this section. You must

[[Page 704]]

install, operate, and maintain each CPMS specified in paragraph (b) of 
this section according to paragraphs (a)(5) through (7) of this section.
    (1) Each CPMS must complete a minimum of one cycle of operation for 
each successive 15-minute period. You must have a minimum of four 
equally spaced successive cycles of CPMS operation to have a valid hour 
of data.
    (2) You must have valid data from at least 90 percent of the hours 
during which the process operated.
    (3) You must determine the hourly average of all recorded readings 
according to paragraphs (a)(3)(i) and (ii) of this section.
    (i) To calculate a valid hourly value, you must have at least three 
of four equally spaced data values from that hour from a continuous 
monitoring system (CMS) that is not out-of-control.
    (ii) Provided all of the readings recorded in accordance with 
paragraph (a)(3) of this section clearly demonstrate continuous 
compliance with the standard that applies to you, then you are not 
required to determine the hourly average of all recorded readings.
    (4) You must determine the rolling 3-hour average of all recorded 
readings for each operating period. To calculate the average for each 3-
hour averaging period, you must have at least two of three of the hourly 
averages for that period using only average values that are based on 
valid data (i.e., not from out-of-control periods).
    (5) You must record the results of each inspection, calibration, and 
validation check of the CPMS.
    (6) At all times, you must maintain the monitoring system in proper 
working order including, but not limited to, maintaining necessary parts 
for routine repairs of the monitoring equipment.
    (7) Except for monitoring malfunctions, associated repairs, or 
required quality assurance or control activities (including calibration 
checks or required zero and span adjustments), you must conduct all 
monitoring at all times that the unit is operating. Data recorded during 
monitoring malfunctions, associated repairs, out-of-control periods, or 
required quality assurance or control activities shall not be used for 
purposes of calculating the emissions concentrations and percent 
reductions specified in Table 1 to this subpart. You must use all the 
valid data collected during all other periods in assessing compliance of 
the control device and associated control system. A monitoring 
malfunction is any sudden, infrequent, not reasonably preventable 
failure of the monitoring system to provide valid data. Monitoring 
failures that are caused in part by poor maintenance or careless 
operation are not malfunctions.
    (8) Any averaging period for which you do not have valid monitoring 
data and such data are required constitutes a deviation, and you must 
notify the Administrator in accordance with Sec. 63.4311(a).
    (b) Capture system bypass line. You must meet the requirements of 
paragraphs (a)(5) through (6) and (b)(1) and (2) of this section for 
each emission capture system that contains bypass lines that could 
divert emissions away from the add-on control device to the atmosphere.
    (1) You must monitor or secure the valve or closure mechanism 
controlling the bypass line in a nondiverting position in such a way 
that the valve or closure mechanism cannot be opened without creating a 
record that the valve was opened. The method used to monitor or secure 
the valve or closure mechanism must meet one of the requirements 
specified in paragraphs (b)(1)(i) through (iv) of this section.
    (i) Flow control position indicator. Install, calibrate, maintain, 
and operate according to the manufacturer's specifications a flow 
control position indicator that takes a reading at least once every 15 
minutes and provides a record indicating whether the emissions are 
directed to the add-on control device or diverted from the add-on 
control device. The time of occurrence and flow control position must be 
recorded, as well as every time the flow direction is changed. The flow 
control position indicator must be installed at the entrance to any 
bypass line that could divert the emissions away from the add-on control 
device to the atmosphere.
    (ii) Car-seal or lock-and-key valve closures. Secure any bypass line 
valve in the closed position with a car-seal or a

lock-and-key type configuration. You must visually inspect the seal or 
closure mechanism at least once every month to ensure that the valve is 
maintained in the closed position, and the emissions are not diverted 
away from the add-on control device to the atmosphere.
    (iii) Valve closure continuous monitoring. Ensure that any bypass 
line valve is in the closed (non-diverting) position through monitoring 
of valve position at least once every 15 minutes. You must inspect the 
monitoring system at least once every month to verify that the monitor 
will indicate valve position.
    (iv) Automatic shutdown system. Use an automatic shutdown system in 
which the web coating/printing or dyeing/finishing operation is stopped 
when flow is diverted by the bypass line away from the add-on control 
device to the atmosphere when the web coating/printing or dyeing/
finishing operation is running. You must inspect the automatic shutdown 
system at least once every month to verify that it will detect 
diversions of flow and shutdown the web coating/printing or dyeing/
finishing operation.
    (2) If any bypass line is opened, you must include a description of 
why the bypass line was opened and the length of time it remained open 
in the semiannual compliance reports required in Sec. 63.4311.
    (c) Oxidizers. If you are using an oxidizer to comply with the 
emission standards, you must comply with paragraphs (c)(i) through (iii) 
of this section.
    (i) Install, calibrate, maintain, and operate temperature monitoring 
equipment according to the manufacturer's specifications. The 
calibration of the chart recorder, data logger, or temperature indicator 
must be verified every 3 months or the chart recorder, data logger, or 
temperature indicator must be replaced.
    (ii) For an oxidizer other than a catalytic oxidizer, install, 
calibrate, operate, and maintain a temperature monitoring device 
equipped with a continuous recorder. The device must have an accuracy of 
1 percent of the temperature being monitored in 
degrees Celsius, or 1 [deg]Celsius, whichever is 
greater. The thermocouple or temperature sensor must be installed in the 
combustion chamber at a location in the combustion zone.
    (iii) For a catalytic oxidizer, install, calibrate, operate, and 
maintain a temperature monitoring device equipped with a continuous 
recorder. The device must be capable of monitoring temperature with an 
accuracy of 1 percent of the temperature being 
monitored in degrees Celsius or 1 degree Celsius, 
whichever is greater. The thermocouple or temperature sensor must be 
installed in the vent stream at the nearest feasible point to the inlet 
and outlet of the catalyst bed. Calculate the temperature rise across 
the catalyst.
    (d) Other types of control devices. If you use a control device 
other than an oxidizer or wish to monitor an alternative parameter and 
comply with a different operating limit, you must apply to the 
Administrator for approval of an alternative monitoring method under 
Sec. 63.8(f).
    (e) Capture system monitoring. If you are complying with the 
emission standards in Sec. 63.4290 through the use of a capture system 
and control device, you must develop a site-specific monitoring plan 
containing the information specified in paragraphs (e)(1) and (2) of 
this section for these capture systems. You must monitor the capture 
system in accordance with paragraph (e)(3) of this section. You must 
make the monitoring plan available for inspection by the permitting 
authority upon request.
    (1) The monitoring plan must:
    (i) Identify the operating parameter to be monitored to ensure that 
the capture efficiency determined during the initial compliance test is 
maintained; and
    (ii) Explain why this parameter is appropriate for demonstrating 
ongoing compliance; and
    (iii) Identify the specific monitoring procedures.
    (2) The monitoring plan must specify the operating parameter value 
or range of values that demonstrate compliance with the emission 
standards in Sec. 63.4290. The specified operating parameter value or 
range of values must represent

[[Page 706]]

the conditions present when the capture system is being properly 
operated and maintained.
    (3) You must conduct all capture system monitoring in accordance 
with the plan.
    (4) Any deviation from the operating parameter value or range of 
values which are monitored according to the plan will be considered a 
deviation from the operating limit.
    (5) You must review and update the capture system monitoring plan at 
least annually.

Sec. 63.4371  What definitions apply to this subpart?

    Terms used in this subpart are defined in the CAA, in 40 CFR 63.2, 
and in this section as follows:
    Add-on control means an air pollution control device, such as a 
thermal oxidizer or carbon adsorber, that reduces pollution in an air 
stream by destruction or removal before discharge to the atmosphere.
    As-applied means the condition of a coating at the time of 
application to a substrate, including any added solvent.
    As purchased means the condition of a coating, printing, slashing, 
dyeing, or finishing material as delivered to the affected source, 
before alteration.
    Capture device means a hood, enclosure, room, floor sweep, or other 
means of containing or collecting emissions and directing those 
emissions into an add-on air pollution control device.
    Capture efficiency means the portion (expressed as a percentage) of 
the pollutants from an emission source that is delivered to an add-on 
control device.
    Capture system means one or more capture devices intended to collect 
emissions generated by a web coating/printing or dyeing/finishing 
operation in the use of regulated materials, both at the point of 
application and at subsequent points where emissions from the regulated 
materials occur, such as flashoff, drying, or curing. As used in this 
subpart, multiple capture devices that collect emissions generated by a 
web coating/printing or dyeing/finishing operation are considered a 
single capture system.
    Cleaning material means a solvent used to remove contaminants and 
other materials, such as dirt, grease, or oil, from a textile before a 
web coating/printing operation (surface preparation) or from equipment 
associated with the web coating/ printing operation, such as tanks, 
rollers, rotary screens, and knife or wiper blades. Thus, it includes 
any cleaning material used in the web coating and printing subcategory 
for surface preparation of substrates or process operation equipment 
cleaning or both with the exception of cleaning material applied to the 
substrate using handheld, non-refillable aerosol containers.

[[Page 707]]

    Coating means the application of a semi-liquid coating material to 
one or both sides of a textile web substrate. Once the coating material 
is dried (and cured, if necessary), it bonds with the textile to form a 
continuous solid film for decorative, protective, or functional 
purposes. Coating does not include finishing where the fiber is 
impregnated with a chemical or resin to impart certain properties, but a 
solid film is not formed.
    Coating material means an elastomer, polymer, or prepolymer material 
applied as a thin layer to a textile web. Such materials include, but 
are not limited to, coatings, sealants, inks, and adhesives. Decorative, 
protective, or functional materials that consist only of acids, bases, 
or any combination of these substances are not considered coating 
material for the purposes of this subpart. Thinning materials also are 
not included in this definition of coating materials, but are accounted 
for separately.
    Coating operation means equipment used to apply cleaning materials 
to a web substrate to prepare it for coating material application 
(surface preparation), to apply coating material to a web substrate 
(coating application) and to dry or cure the coating material after 
application by exposure to heat or radiation (coating drying or curing), 
or to clean coating operation equipment (equipment cleaning). A single 
coating operation may include any combination of these types of 
equipment, but always includes at least the point at which a coating or 
cleaning material is applied and all subsequent points in the affected 
source where organic HAP emissions from that coating or cleaning 
material occur. There may be multiple coating operations in an affected 
source. Coating material application with handheld, non-refillable 
aerosol containers, touch-up markers, or marking pens is not a coating 
operation for the purposes of this subpart. Polyurethane foam carpet 
backing operations are not coating operations for the purposes of this 
subpart.
    Container means any portable device in which a material is stored, 
conveyed, treated, disposed of, or otherwise handled.
    Continuous parameter monitoring system means the total equipment

analyze, and provide a record of coating or printing operation, or 
capture system, or add-on control device parameters.
    Controlled web coating/printing or dyeing/finishing operation means 
a web coating/printing or dyeing/finishing operation from which some or 
all of the organic HAP emissions are routed through an emission capture 
system and add-on control device.
    Deviation means any instance in which an affected source subject to 
this subpart, or an owner or operator of such a source:
    (1) Fails to meet any requirement or obligation established by this 
subpart, including but not limited to any emission limit, or operating 
limit, or work practice standard;
    (2) Fails to meet any term or condition that is adopted to implement 
an applicable requirement in this subpart and that is included in the 
operating permit for any affected source required to obtain such a 
permit; or
    (3) Fails to meet any emission limit, or operating limit, or work 
practice standard in this subpart during startup, shutdown, or 
malfunction, regardless of whether or not such failure is permitted by 
this subpart.
    Dyeing means the process of applying color to the whole body of a 
textile substrate with either natural or synthetic dyes. Dyes are 
applied to yarn, fiber, cord, or fabric in aqueous solutions and dried 
before or after finishing, depending on the process. Continuous dyeing 
processes include, but are not limited to thermosol, pad/steam, pad/dry, 
and rope range dyeing. Batch dyeing processes include, but are not 
limited to, jet, beck, stock, yarn, kier, beam, pad, package and skein 
dyeing.
    Dyeing materials means the purchased dyes and dyeing auxiliaries 
that are used in the dyeing process. The dyes are the substances that 
add color to textiles through incorporation into the fiber by chemical 
reaction, absorption or dispersion. Dyeing auxiliaries are various 
substances that can be added

[[Page 708]]

to the dyebath to aid dyeing. Dyeing auxiliaries may be necessary to 
transfer the dye from the dyebath to the fiber or they may provide 
improvements in the dyeing process or characteristics of the dyed fiber.
    Dyeing operation means the collection of equipment used to dye a 
textile substrate and includes equipment used for dye application, dye 
fixation, and textile substrate rinsing and drying. A single dyeing 
operation may include any combination of these types of equipment, but 
always includes at least the point at which a dyeing material is applied 
and all subsequent points in the affected source where organic HAP 
emissions from that dyeing material occur. There may be multiple dyeing 
operations in an affected source. Dyeing material application with 
handheld, non-refillable aerosol containers, touch-up markers, brushes, 
or marking pens is not a dyeing operation for the purposes of this 
subpart.
    Emission limitation means an emission limit, operating limit, or 
work practice standard.
    Enclosure means a structure that surrounds a source of emissions and 
captures and directs the emissions to an add-on control device.

finish a textile substrate including chemical finish applicator(s), 
flashoff area(s) and drying or curing oven(s).
    Laminated fabric means fabric composed of a high-strength 
reinforcing base fabric between two plies of flexible thermoplastic 
film. Two or more fabrics or textiles or a fabric and a paper substrate 
may be bonded with an adhesive to form a laminate. The bonding of a 
fabric substrate to paper is not subject to the requirements of this 
subpart.
    Manufacturer's formulation data means data on a material (such as a 
coating, printing, slashing, dyeing and finishing) that are supplied by 
the material manufacturer based on knowledge of the ingredients used to 
manufacture that material, rather than based on testing of the material.

information on density, organic HAP content, and coating, printing, 
dyeing, slashing, finishing, thinning, or cleaning material content.
    Mass fraction of organic HAP means the ratio of the mass of organic 
HAP to the mass of a material in which it is contained; kg of organic 
HAP per kg of material.
    Month means a calendar month or a pre-specified period of 28 days to 
35 days to allow for flexibility in recordkeeping when data are based on 
a business accounting period.

mass or more for OSHA-defined carcinogens as specified in 29 CFR 
1910.1200(d)(4) and at 1.0 percent by mass or more for other compounds. 
The organic HAP content of a regulated material is determined according 
to Sec. 63.4321(e)(1).
    Operating scenario means for a dyeing/finishing process operation or 
group of process operations, the combination of operating conditions 
(including but not limited to, type of substrate, type and mass fraction 
of organic HAP in dyeing/finishing materials applied, and the process 
operation temperature and pressure) affecting the fraction of organic 
HAP applied in dyeing and finishing operations discharged to wastewater. 
For example, a dyeing process operation run at atmospheric pressure 
would be a different operating scenario

[[Page 709]]

from the same dyeing process operation run under pressure.
    Organic HAP content means the mass of organic HAP per mass of solids 
for a coating or printing material calculated using Equation 1 of Sec. 
63.4321. The organic HAP content is determined for the coating or 
printing material as purchased.
    Organic HAP overall control efficiency means the total efficiency of 
a control system, determined either by:
    (1) The product of the capture efficiency as determined in 
accordance with the requirements of Sec. 63.4361 and the control device

part 51, for a PTE and that directs all the exhaust gases from the 
enclosure to an add-on control device.
    Point of determination means each point where process wastewater 
exits the dyeing/finishing process unit.
    Printing means the application of color and patterns to textiles, 
usually in the form of a paste, using a variety of techniques including, 
but not limited to roller, rotary screen, and ink jet printing. After 
application of the printing material, the textile usually is treated 
with steam, heat, or chemicals to fix the color.
    Printing material means the purchased substances, usually including 
gums or thickeners, dyes and appropriate chemicals such as defoamers and

 Subpart PPPP_National Emission Standards for Hazardous Air Pollutants 
            for Surface Coating of Plastic Parts and Products

    Source: 69 FR 20990, Apr. 19, 2004, unless otherwise noted.

                        What This Subpart Covers



Sec. 63.4480  What is the purpose of this subpart?

    This subpart establishes national emission standards for hazardous 
air pollutants (NESHAP) for plastic parts and products surface coating 
facilities. This subpart also establishes requirements to demonstrate 
initial and continuous compliance with the emission limitations.



Sec. 63.4481  Am I subject to this subpart?

    (a) Plastic parts and products include, but are not limited to, 
plastic components of the following types of products as well as the 
products themselves: Motor vehicle parts and accessories for 
automobiles, trucks, recreational vehicles; sporting and recreational 
goods; toys; business machines; laboratory and medical equipment; and 
household and other consumer products. Except as provided in paragraph 
(c) of this section, the source category to which this subpart applies 
is the surface coating of any plastic parts or products, as described in 
paragraph (a)(1) of this section, and it includes the subcategories 
listed in paragraphs (a)(2) through (5) of this section.
    (1) Surface coating is the application of coating to a substrate 
using, for example, spray guns or dip tanks. When application of coating 
to a substrate occurs, then surface coating also includes associated 
activities, such as surface preparation, cleaning, mixing, and storage. 
However, these activities do not comprise surface coating if they

[[Page 717]]

are not directly related to the application of the coating. Coating 
application with handheld, non-refillable aerosol containers, touch-up 
markers, marking pens, or the application of paper film or plastic film 
which may be pre-coated with an adhesive by the manufacturer are not 
coating operations for the purposes of this subpart.
    (2) The general use coating subcategory includes all surface coating 
operations that are not automotive lamp coating operations, 
thermoplastic olefin (TPO) coating operations, or assembled on-road 
vehicle coating operations.
    (3) The automotive lamp coating subcategory includes the surface 
coating of plastic components of the body of an exterior automotive lamp 
including, but not limited to, headlamps, tail lamps, turn signals, and 
marker (clearance) lamps; typical coatings used are reflective argent 
coatings and clear topcoats. This subcategory does not include the 
coating of interior automotive lamps, such as dome lamps and instrument 
panel lamps.
    (4) The TPO coating subcategory includes the surface coating of TPO 
substrates; typical coatings used are adhesion promoters, color 
coatings, clear coatings and topcoats. The coating of TPO substrates on 
fully assembled on-road vehicles is not included in the TPO coating 
subcategory.
    (5) The assembled on-road vehicle coating subcategory includes 
surface coating of fully assembled motor vehicles and trailers intended 
for on-road use, including, but not limited to: automobiles, light-duty 
trucks, heavy duty trucks, and busses that have been repaired after a 
collision or otherwise repainted; fleet delivery trucks; and motor homes 
and other recreational vehicles (including camping trailers and fifth 
wheels). This subcategory also includes the incidental coating of parts, 
such as radiator grilles, that are removed from the fully assembled on-
road vehicle to facilitate concurrent coating of all parts associated 
with the vehicle. The assembled on-road vehicle coating subcategory does 
not include the surface coating of plastic parts prior to their 
attachment to an on-road vehicle on an original equipment manufacturer's 
(OEM) assembly line. The assembled on-road vehicle coating subcategory 
also does not include the use of adhesives, sealants, and caulks used in 
assembling on-road vehicles. Body fillers used to correct small surface 
defects and rubbing compounds used to remove surface scratches are not 
considered coatings subject to this subpart.
    (b) You are subject to this subpart if you own or operate a new, 
reconstructed, or existing affected source, as defined in Sec. 63.4482, 
that uses 378 liters (100 gallons (gal)) per year, or more, of coatings 
that contain hazardous air pollutants (HAP) in the surface coating of 
plastic parts and products defined in paragraph (a) of this section; and 
that is a major source, is located at a major source, or is part of a 
major source of emissions of HAP. A major source of HAP emissions is any 
stationary source or group of stationary sources located within a 
contiguous area and under common control that emits or has the potential 
to emit any single HAP at a rate of 9.07 megagrams (Mg) (10 tons) or 
more per year or any combination of HAP at a rate of 22.68 Mg (25 tons) 
or more per year. You do not need to include coatings that meet the 
definition of non-HAP coating contained in Sec. 63.4581 in determining 
whether you use 378 liters (100 gallons) per year, or more, of coatings 
in the surface coating of plastic parts and products.
    (c) This subpart does not apply to surface coating or a coating 
operation that meets any of the criteria of paragraphs (c)(1) through 
(17) of this section.
    (1) A coating operation conducted at a facility where the facility 
uses only coatings, thinners and other additives, and cleaning materials 
that contain no organic HAP, as determined according to Sec. 
63.3941(a).
    (2) Surface coating operations that occur at research or laboratory 
facilities, or is part of janitorial, building, and facility maintenance 
operations, or that occur at hobby shops that are operated for 
noncommercial purposes.
    (3) The surface coating of plastic parts and products performed on-
site at installations owned or operated by the

[[Page 718]]

Armed Forces of the United States (including the Coast Guard and the 
National Guard of any such State) or the National Aeronautics and Space 
Administration, or the surface coating of military munitions 
manufactured by or for the Armed Forces of the United States (including 
the Coast Guard and the National Guard of any such State).
    (4) Surface coating where plastic is extruded onto plastic parts or 
products to form a coating.
    (5) Surface coating of magnet wire.
    (6) In-mold coating operations or gel coating operations in the 
manufacture of reinforced plastic composite parts that meet the 
applicability criteria for reinforced plastics composites production 
(subpart WWWW of this part).
    (7) Surface coating of plastic components of wood furniture that 
meet the applicability criteria for wood furniture manufacturing 
(subpart JJ of this part).
    (8) Surface coating of plastic components of large appliances that 
meet the applicability criteria for large appliance surface coating 
(subpart NNNN of this part).
    (9) Surface coating of plastic components of metal furniture that 
meet the applicability criteria for metal furniture surface coating 
(subpart RRRR of this part).
    (10) Surface coating of plastic components of wood building products 
that meet the applicability criteria for wood building products surface 
coating (subpart QQQQ of this part).
    (11) Surface coating of plastic components of aerospace vehicles 
that meet the applicability criteria for aerospace manufacturing and 
rework (40 CFR part 63, subpart GG).
    (12) Surface coating of plastic parts intended for use in an 
aerospace vehicle or component using specialty coatings as defined in 
appendix A to subpart GG of this part.
    (13) Surface coating of plastic components of ships that meet the 
applicability criteria for shipbuilding and ship repair (subpart II of 
this part).
    (14) Surface coating of plastic using a web coating process that 
meets the applicability criteria for paper and other web coating 
(subpart JJJJ of this part).
    (15) Surface coating of fiberglass boats or parts of fiberglass 
boats (including, but not limited to, the use of assembly adhesives) 
where the facility meets the applicability criteria for boat 
manufacturing (subpart VVVV of this part), except where the surface 
coating of the boat is a post-mold coating operation performed on 
personal watercraft or parts of personal watercraft. This subpart does 
apply to post-mold coating operations performed on personal watercraft 
and parts of personal watercraft.
    (16) Surface coating of plastic components of automobiles and light-
duty trucks that meet the applicability criteria in Sec. 63.3082(b) of 
the Surface Coating of Automobiles and Light-Duty Trucks NESHAP (40 CFR 
part 63, subpart IIII) at a facility that meets the applicability 
criteria in Sec. 63.3081(b).
    (17) Screen printing.
    (d) If your facility meets the applicability criteria in Sec. 
63.3081(b) of the Surface Coating of Automobiles and Light-Duty Trucks 
NESHAP (40 CFR part 63, subpart IIII) and you perform surface coating of 
plastic parts or products that meets both the applicability criteria in 
Sec. 63.3082(c) and the applicability criteria of this subpart, then 
for the surface coating of any or all of your plastic parts or products 
that meets the applicability criteria in Sec. 63.3082(c), you may 
choose to comply with the requirements of subpart IIII of this part in 
lieu of complying with this subpart. Surface coating operations on 
plastic parts or products (e.g., parts for motorcycles or lawnmowers) 
not intended for use in automobiles, light-duty trucks, or other motor 
vehicles as defined in Sec. 63.3176 cannot be made part of your 
affected source under subpart IIII of this part.
    (e) If you own or operate an affected source that meets the 
applicability criteria of this subpart and at the same facility you also 
perform surface coating that meets the applicability criteria of any 
other final surface coating NESHAP in this part, you may choose to 
comply as specified in paragraph (e)(1), (2), or (3) of this section.
    (1) You may have each surface coating operation that meets the 
applicability criteria of a separate NESHAP comply with that NESHAP 
separately.

[[Page 719]]

    (2) You may comply with the emission limitation representing the 
predominant surface coating activity at your facility, as determined 
according to paragraphs (e)(2)(i) and (ii) of this section. However, you 
may not establish assembled on-road vehicle or automotive lamp coating 
operations as the predominant activity. You must not consider any 
surface coating activity that is subject to the Surface Coating of 
Automobiles and Light-Duty Trucks NESHAP (40 CFR part 63, subpart IIII) 
in determining the predominant surface coating activity at your 
facility.
    (i) If a surface coating operation accounts for 90 percent or more 
of the surface coating activity at your facility (that is, the 
predominant activity), then compliance with the emission limitations of 
the predominant activity for all surface coating operations constitutes 
compliance with these and other applicable surface coating NESHAP. In 
determining predominant activity, you must include coating activities 
that meet the applicability criteria of other surface coating NESHAP and 
constitute more than 1 percent of total coating activities at your 
facility. Coating activities that meet the applicability criteria of 
other surface coating NESHAP but comprise less than 1 percent of coating 
activities need not be included in the determination of predominant 
activity but must be included in the compliance calculation.
    (ii) You must use kilogram (kg) (pound (lb)) of solids used as a 
measure of relative surface coating activity over a representative 
period of operation. You may estimate the relative mass of coating 
solids used from parameters other than coating consumption and mass 
solids content (e.g., design specifications for the parts or products 
coated and the number of items produced). The determination of 
predominant activity must accurately reflect current and projected 
coating operations and must be verifiable through appropriate 
documentation. The use of parameters other than coating consumption and 
mass solids content must be approved by the Administrator. You may use 
data for any reasonable time period of at least 1 year in determining 
the relative amount of coating activity, as long as they represent the 
way the source will continue to operate in the future and are approved 
by the Administrator. You must determine the predominant activity at 
your facility and submit the results of that determination with the 
initial notification required by Sec. 63.4510(b). You must also 
determine predominant activity annually and include the determination in 
the next semi-annual compliance report required by Sec. 63.4520(a).
    (3) You may comply with a facility-specific emission limit 
calculated from the relative amount of coating activity that is subject 
to each emission limit. If you elect to comply using the facility-
specific emission limit alternative, then compliance with the facility-
specific emission limit and the emission limitations in this subpart for 
all surface coating operations constitutes compliance with this subpart 
and other applicable surface coating NESHAP. The procedures for 
calculating the facility-specific emission limit are specified in Sec. 
63.4490. In calculating a facility-specific emission limit, you must 
include coating activities that meet the applicability criteria of other 
surface coating NESHAP and constitute more than 1 percent of total 
coating activities at your facility. You must not consider any surface 
coating activity that is subject to the Surface Coating of Automobiles 
and Light-Duty Trucks NESHAP (40 CFR part 63, subpart IIII) in 
determining a facility-specific emission limit for your facility. 
Coating activities that meet the applicability criteria of other surface 
coating NESHAP but comprise less than 1 percent of total coating 
activities need not be included in the calculation of the facility-
specific emission limit but must be included in the compliance 
calculations.

    (d) An affected source is reconstructed if you meet the criteria as 
defined in Sec. 63.2.
    (e) An affected source is existing if it is not new or 
reconstructed.



Sec. 63.4483  When do I have to comply with this subpart?

    The date by which you must comply with this subpart is called the 
compliance date. The compliance date for each type of affected source is 
specified in paragraphs (a) through (c) of this section. The compliance 
date begins the initial compliance period during which you conduct the 
initial compliance demonstration described in Sec. Sec. 63.4540, 
63.4550, and 63.4560.
    (a) For a new or reconstructed affected source, the compliance date 
is the applicable date in paragraph (a)(1) or (2) of this section:
    (1) If the initial startup of your new or reconstructed affected 
source is before April 19, 2004, the compliance date is April 19, 2004.
    (2) If the initial startup of your new or reconstructed affected 
source occurs after April 19, 2004, the compliance date is the date of 
initial startup of your affected source.
    (b) For an existing affected source, the compliance date is the date 
3 years after April 19, 2004.
    (c) For an area source that increases its emissions or its potential 
to emit such that it becomes a major source of HAP emissions, the 
compliance date is specified in paragraphs (c)(1) and (2) of this 
section.
    (1) For any portion of the source that becomes a new or 
reconstructed affected source subject to this subpart, the compliance 
date is the date of initial startup of the affected source or April 19, 
2004, whichever is later.
    (2) For any portion of the source that becomes an existing affected 
source subject to this subpart, the compliance date is the date 1 year 
after the area source becomes a major source or 3 years after April 19, 
2004, whichever is later.
    (d) You must meet the notification requirements in Sec. 63.4510 
according to the dates specified in that section and in subpart A of 
this part. Some of the notifications must be submitted before the 
compliance dates described in paragraphs (a) through (c) of this 
section.

                          Emission Limitations



Sec. 63.4490  What emission limits must I meet?

    (a) For a new or reconstructed affected source, you must limit 
organic HAP emissions to the atmosphere from the affected source to the 
applicable limit specified in paragraphs (a)(1) through (4) of this 
section, except as specified in paragraph (c) of this section, 
determined according to the requirements in Sec. 63.4541, Sec. 
63.4551, or Sec. 63.4561.
    (1) For each new general use coating affected source, limit organic 
HAP emissions to no more than 0.16 kg (0.16 lb) organic HAP emitted per 
kg (lb) coating solids used during each 12-month compliance period.

[[Page 721]]

    (2) For each new automotive lamp coating affected source, limit 
organic HAP emissions to no more than 0.26 kg (0.26 lb) organic HAP 
emitted per kg (lb) coating solids used during each 12-month compliance 
period.
    (3) For each new TPO coating affected source, limit organic HAP 
emissions to no more than 0.22 kg (0.22 lb) organic HAP emitted per kg 
(lb) coating solids used during each 12-month compliance period.
    (4) For each new assembled on-road vehicle coating affected source, 
limit organic HAP emissions to no more than 1.34 kg (1.34 lb) organic 
HAP emitted per kg (lb) coating solids used during each 12-month 
compliance period.
    (b) For an existing affected source, you must limit organic HAP 
emissions to the atmosphere from the affected source to the applicable 
limit specified in paragraphs (b)(1) through (4) of this section, except 
as specified in paragraph (c) of this section, determined according to 
the requirements in Sec. 63.4541, Sec. 63.4551, or Sec. 63.4561.
    (1) For each existing general use coating affected source, limit 
organic HAP emissions to no more than 0.16 kg (0.16 lb) organic HAP 
emitted per kg (lb) coating solids used during each 12-month compliance 
period.
    (2) For each existing automotive lamp coating affected source, limit 
organic HAP emissions to no more than 0.45 kg (0.45 lb) organic HAP 
emitted per kg (lb) coating solids used during each 12-month compliance 
period.
    (3) For each existing TPO coating affected source, limit organic HAP 
emissions to no more than 0.26 kg (0.26 lb) organic HAP emitted per kg 
(lb) coating solids used during each 12-month compliance period.
    (4) For each existing assembled on-road vehicle coating affected 
source, limit organic HAP emissions to no more than 1.34 kg (1.34 lb) 
organic HAP emitted per kg (lb) coating solids used during each 12-month 
compliance period.
    (c) If your facility's surface coating operations meet the 
applicability criteria of more than one of the subcategory emission 
limits specified in paragraphs (a) or (b) of this section, you may 
comply separately with each subcategory emission limit or comply using 
one of the alternatives in paragraph (c)(1) or (2) of this section.
    (1) If the general use or TPO surface coating operations subject to 
only one of the emission limits specified in paragraphs (a)(1), (a)(3), 
(b)(1), or (b)(3) of this section account for 90 percent or more of the 
surface coating activity at your facility (i.e., it is the predominant 
activity at your facility), then compliance with that emission 
limitation for all surface coating operations constitutes compliance 
with the other applicable emission limitations. You must use kg (lb) of 
solids used as a measure of relative surface coating activity over a 
representative period of operation. You may estimate the relative mass 
of coating solids used from parameters other than coating consumption 
and mass solids content (e.g., design specifications for the parts or 
products coated and the number of items produced). The determination of 
predominant activity must accurately reflect current and projected 
coating operations and must be verifiable through appropriate 
documentation. The use of parameters other than coating consumption and 
mass solids content must be approved by the Administrator. You may use 
data for any reasonable time period of at least 1 year in determining 
the relative amount of coating activity, as long as they represent the 
way the source will continue to operate in the future and are approved 
by the Administrator. You must determine the predominant activity at 
your facility and submit the results of that determination with the 
initial notification required by Sec. 63.4510(b). Additionally, you 
must determine the facility's predominant activity annually and include 
the determination in the next semi-annual compliance report required by 
Sec. 63.4520(a).
    (2) You may calculate and comply with a facility-specific emission 
limit as described in paragraphs (c)(2)(i) through (iii) of this 
section. If you elect to comply using the facility-specific emission 
limit alternative, then compliance with the facility-specific emission 
limit and the emission limitations in this subpart for all surface 
coating operations constitutes compliance with this and other applicable

[[Page 722]]

surface coating NESHAP. In calculating a facility-specific emission 
limit, you must include coating activities that meet the applicability 
criteria of the other subcategories and constitute more than 1 percent 
of total coating activities. Coating activities that meet the 
applicability criteria of other surface coating NESHAP but comprise less 
than 1 percent of coating activities need not be included in the 
determination of predominant activity but must be included in the 
compliance calculation.
    (i) You are required to calculate the facility-specific emission 
limit for your facility when you submit the notification of compliance 
status required in Sec. 63.4510(c), and on a monthly basis afterward 
using the coating data for the relevant 12-month compliance period.
    (ii) Use Equation 1 of this section to calculate the facility-
specific emission limit for your surface coating operations for each 12-
month compliance period.
[GRAPHIC] [TIFF OMITTED] TR19AP04.002

Where:

Facility-specific emission limit = Facility-specific emission limit for 
          each 12-month compliance period, kg (lb) organic HAP per kg 
          (lb) coating solids used.
Limiti = The new source or existing source emission limit 
          applicable to coating operation, i, included in the facility-
          specific emission limit, converted to kg (lb) organic HAP per 
          kg (lb) coating solids used, if the emission limit is not 
          already in those units. All emission limits included in the 
          facility-specific emission limit must be in the same units.
Solidsi = The kg (lb) of solids used in coating operation, i, 
          in the 12-month compliance period that is subject to emission 
          limit, i. You may estimate the mass of coating solids used 
          from parameters other than coating consumption and mass solids 
          content (e.g., design specifications for the parts or products 
          coated and the number of items produced). The use of 
          parameters other than coating consumption and mass solids 
          content must be approved by the Administrator.
n = The number of different coating operations included in the facility-
          specific emission limit.

    (iii) If you need to convert an emission limit in another surface 
coating NESHAP from kg (lb) organic HAP per liter (gallon) coating 
solids used to kg (lb) organic HAP per kg (lb) coating solids used, you 
must use the default solids density of 1.50 kg solids per liter coating 
solids (12.5 lb solids per gal solids).



Sec. 63.4491  What are my options for meeting the emission limits?

    You must include all coatings (as defined in Sec. 63.4581), 
thinners and/or other additives, and cleaning materials used in the 
affected source when determining whether the organic HAP emission rate 
is equal to or less than the applicable emission limit in Sec. 63.4490. 
To make this determination, you must use at least one of the three 
compliance options listed in paragraphs (a) through (c) of this section. 
You may apply any of the compliance options to an individual coating 
operation, or to multiple coating operations as a group, or to the 
entire affected source. You may use different compliance options for 
different coating operations, or at different times on the same coating 
operation. You may employ different compliance options when different 
coatings are applied to the same part, or when the same coating is 
applied to different parts. However, you may not use different 
compliance options at the same time on the same coating operation. If 
you switch between compliance options for any coating operation or group 
of coating operations, you must document this switch as required

[[Page 723]]

by Sec. 63.4530(c), and you must report it in the next semiannual 
compliance report required in Sec. 63.4520.
    (a) Compliant material option. Demonstrate that the organic HAP 
content of each coating used in the coating operation(s) is less than or 
equal to the applicable emission limit in Sec. 63.4490, and that each 
thinner and/or other additive, and cleaning material used contains no 
organic HAP. You must meet all the requirements of Sec. Sec. 63.4540, 
63.4541, and 63.4542 to demonstrate compliance with the applicable 
emission limit using this option.

        Compliance Requirements for the Compliant Material Option



Sec. 63.4540  By what date must I conduct the initial compliance
demonstration?

    You must complete the initial compliance demonstration for the 
initial compliance period according to the requirements in Sec. 
63.4541. The initial compliance period begins on the applicable 
compliance date specified in Sec. 63.4483 and ends on the last day of 
the 12th month following the compliance date. If the compliance date 
occurs on any day other than the first day of a month, then the initial 
compliance period extends through that month plus the next 12 months. 
The initial compliance demonstration includes the calculations according 
to Sec. 63.4541 and supporting documentation showing that during the 
initial compliance period, you used no coating with an organic HAP 
content that exceeded the applicable emission limit in Sec. 63.4490, 
and that you used no thinners and/or other additives, or cleaning 
materials that contained organic HAP as determined according to Sec. 
63.4541(a).



Sec. 63.4541  How do I demonstrate initial compliance with the
emission limitations?

    You may use the compliant material option for any individual coating 
operation, for any group of coating operations in the affected source, 
or for all the coating operations in the affected source. You must use 
either the emission rate without add-on controls option or the emission 
rate with add-on controls option for any coating operation in the 
affected source for which you do not use this option. To demonstrate 
initial compliance using the compliant material option, the coating 
operation or group of coating operations must use no coating with an 
organic HAP content that exceeds the applicable emission limits in Sec. 
63.4490 and must use no thinner and/or other additive, or cleaning 
material that contains organic HAP as determined according to this 
section. Any coating operation for which you use the compliant material 
option is not required to meet the operating limits or work practice 
standards required in Sec. Sec. 63.4492 and 63.4493, respectively. You 
must conduct a separate initial compliance demonstration for each 
general use coating, TPO coating, automotive lamp coating, and assembled 
on-road vehicle coating affected source unless you are demonstrating 
compliance with a predominant activity or facility-specific emission 
limit as provided in Sec. 63.4490(c). If you are demonstrating 
compliance with a predominant activity or facility-specific emission 
limit as provided in Sec. 63.4490(c), you must demonstrate that all 
coating operations included in the predominant activity determination or 
calculation of the facility-specific emission limit comply with that 
limit. You must meet all the requirements of this section. Use the 
procedures in this section on

[[Page 733]]

each coating, thinner and/or other additive, and cleaning material in 
the condition it is in when it is received from its manufacturer or 
supplier and prior to any alteration. You do not need to redetermine the 
organic HAP content of coatings, thinners and/or other additives, and 
cleaning materials that are reclaimed on-site (or reclaimed off-site if 
you have documentation showing that you received back the exact same 
materials that were sent off-site) and reused in the coating operation 
for which you use the compliant material option, provided these 
materials in their condition as received were demonstrated to comply 
with the compliant material option.
    (a) Determine the mass fraction of organic HAP for each material 
used. You must determine the mass fraction of organic HAP for each 
coating, thinner and/or other additive, and cleaning material used 
during the compliance period by using one of the options in paragraphs 
(a)(1) through (5) of this section.
    (1) Method 311 (appendix A to 40 CFR part 63). You may use Method 
311 for determining the mass fraction of organic HAP. Use the procedures 
specified in paragraphs (a)(1)(i) and (ii) of this section when 
performing a Method 311 test.
    (i) Count each organic HAP that is measured to be present at 0.1 
percent by mass or more for Occupational Safety and Health 
Administration (OSHA)-defined carcinogens as specified in 29 CFR 
1910.1200(d)(4) and at 1.0 percent by mass or more for other compounds. 
For example, if toluene (not an OSHA carcinogen) is measured to be 0.5 
percent of the material by mass, you do not have to count it. Express 
the mass fraction of each organic HAP you count as a value truncated to 
four places after the decimal point (e.g., 0.3791).
    (ii) Calculate the total mass fraction of organic HAP in the test 
material by adding up the individual organic HAP mass fractions and 
truncating the result to three places after the decimal point (e.g., 
0.763).
    (2) Method 24 (appendix A to 40 CFR part 60). For coatings, you may 
use Method 24 to determine the mass fraction of nonaqueous volatile 
matter and use that value as a substitute for mass fraction of organic 
HAP. For reactive adhesives in which some of the HAP react to form 
solids and are not emitted to the atmosphere, you may use the 
alternative method contained in appendix A to this subpart, rather than 
Method 24. You may use the volatile fraction that is emitted, as 
measured by the alternative method in appendix A to this subpart, as a 
substitute for the mass fraction of organic HAP.
    (3) Alternative method. You may use an alternative test method for 
determining the mass fraction of organic HAP once the Administrator has 
approved it. You must follow the procedure in Sec. 63.7(f) to submit an 
alternative test method for approval.
    (4) Information from the supplier or manufacturer of the material. 
You may rely on information other than that generated by the test 
methods specified in paragraphs (a)(1) through (3) of this section, such 
as manufacturer's formulation data, if it represents each organic HAP 
that is present at 0.1 percent by mass or more for OSHA-defined 
carcinogens as specified in 29 CFR 1910.1200(d)(4) and at 1.0 percent by 
mass or more for other compounds. For example, if toluene (not an OSHA 
carcinogen) is 0.5 percent of the material by mass, you do not have to 
count it. For reactive adhesives in which some of the HAP react to form 
solids and are not emitted to the atmosphere, you may rely on 
manufacturer's data that expressly states the organic HAP or volatile 
matter mass fraction emitted. If there is a disagreement between such 
information and results of a test conducted according to paragraphs 
(a)(1) through (3) of this section, then the test method results will 
take precedence unless, after consultation you demonstrate to the 
satisfaction of the enforcement agency that the formulation data are 
correct.
    (5) Solvent blends. Solvent blends may be listed as single 
components for some materials in data provided by manufacturers or 
suppliers. Solvent blends may contain organic HAP which must be counted 
toward the total organic HAP mass fraction of the materials. When test 
data and manufacturer's data for solvent blends are not available, you 
may use the default values for the

[[Page 734]]

mass fraction of organic HAP in these solvent blends listed in Table 3 
or 4 to this subpart. If you use the tables, you must use the values in 
Table 3 for all solvent blends that match Table 3 entries according to 
the instructions for Table 3, and you may use Table 4 only if the 
solvent blends in the materials you use do not match any of the solvent 
blends in Table 3 and you know only whether the blend is aliphatic or 
aromatic. However, if the results of a Method 311 (appendix A to 40 CFR 
part 63) test indicate higher values than those listed on Table 3 or 4 
to this subpart, the Method 311 results will take precedence unless, 
after consultation you demonstrate to the satisfaction of the 
enforcement agency that the formulation data are correct.
    (b) Determine the mass fraction of coating solids for each coating. 
You must determine the mass fraction of coating solids (kg (lb) of 
coating solids per kg (lb) of coating) for each coating used during the 
compliance period by a test, by information provided by the supplier or 
the manufacturer of the material, or by calculation, as specified in 
paragraphs (b)(1) through (3) of this section.
    (1) Method 24 (appendix A to 40 CFR part 60). Use Method 24 for 
determining the mass fraction of coating solids. For reactive adhesives 
in which some of the liquid fraction reacts to form solids, you may use 
the alternative method contained in appendix A to this subpart, rather 
than Method 24, to determine the mass fraction of coating solids.
    (2) Alternative method. You may use an alternative test method for 
determining the solids content of each coating once the Administrator 
has approved it. You must follow the procedure in Sec. 63.7(f) to 
submit an alternative test method for approval.
    (3) Information from the supplier or manufacturer of the material. 
You may obtain the mass fraction of coating solids for each coating from 
the supplier or manufacturer. If there is disagreement between such 
information and the test method results, then the test method results 
will take precedence unless, after consultation you demonstrate to the 
satisfaction of the enforcement agency that the formulation data are 
correct.
    (c) Calculate the organic HAP content of each coating. Calculate the 
organic HAP content, kg (lb) organic HAP emitted per kg (lb) coating 
solids used, of each coating used during the compliance period using 
Equation 1 of this section:
[GRAPHIC] [TIFF OMITTED] TR19AP04.003

Where:

Hc = Organic HAP content of the coating, kg (lb) of organic 
          HAP emitted per kg (lb) coating solids used.
Wc = Mass fraction of organic HAP in the coating, kg organic 
          HAP per kg coating, determined according to paragraph (a) of 
          this section.
Sc = Mass fraction of coating solids, kg coating solids per 
          kg coating, determined according to paragraph (b) of this 
          section.

    (d) Compliance demonstration. The calculated organic HAP content for 
each coating used during the initial compliance period must be less than 
or equal to the applicable emission limit in Sec. 63.4490; and each 
thinner and/or other additive, and cleaning material used during the 
initial compliance period must contain no organic HAP, determined 
according to paragraph (a) of this section. You must keep all records 
required by Sec. Sec. 63.4530 and 63.4531. As part of the notification 
of compliance status required in Sec. 63.4510, you must identify the 
coating operation(s) for which you used the compliant material option 
and submit a statement that the coating operation(s) was (were) in 
compliance with the emission limitations during the initial compliance 
period because you used no coatings for which the organic HAP content 
exceeded the applicable emission limit in Sec. 63.4490, and you used no 
thinners and/or other additives, or cleaning materials that contained 
organic HAP, determined according to the procedures in paragraph (a) of 
this section.



Sec. 63.4542  How do I demonstrate continuous compliance with the
emission limitations?

    (a) For each compliance period to demonstrate continuous compliance, 
you must use no coating for which the organic HAP content (determined

[[Page 735]]

using Equation 1 of Sec. 63.4541) exceeds the applicable emission limit 
in Sec. 63.4490, and use no thinner and/or other additive, or cleaning 
material that contains organic HAP, determined according to Sec. 
63.4541(a). A compliance period consists of 12 months. Each month, after 
the end of the initial compliance period described in Sec. 63.4540, is 
the end of a compliance period consisting of that month and the 
preceding 11 months. If you are complying with a facility-specific 
emission limit under Sec. 63.4490(c), you must also perform the 
calculation using Equation 1 in Sec. 63.4490(c)(2) on a monthly basis 
using the data from the previous 12 months of operation.
    (b) If you choose to comply with the emission limitations by using 
the compliant material option, the use of any coating, thinner and/or 
other additive, or cleaning material that does not meet the criteria 
specified in paragraph (a) of this section is a deviation from the 
emission limitations that must be reported as specified in Sec. Sec. 
63.4510(c)(6) and 63.4520(a)(5).
    (c) As part of each semiannual compliance report required by Sec. 
63.4520, you must identify the coating operation(s) for which you used 
the compliant material option. If there were no deviations from the 
applicable emission limit in Sec. 63.4490, submit a statement that the 
coating operation(s) was (were) in compliance with the emission 
limitations during the reporting period because you used no coatings for 
which the organic HAP content exceeded the applicable emission limit in 
Sec. 63.4490, and you used no thinner and/or other additive, or 
cleaning material that contained organic HAP, determined according to 
Sec. 63.4541(a).
    (d) You must maintain records as specified in Sec. Sec. 63.4530 and 
63.4531.

 Compliance Requirements for the Emission Rate Without Add-On Controls 
                                 Option



Sec. 63.4550  By what date must I conduct the initial compliance
demonstration?

    You must complete the initial compliance demonstration for the 
initial compliance period according to the requirements of Sec. 
63.4551. The initial compliance period begins on the applicable 
compliance date specified in Sec. 63.4483 and ends on the last day of 
the 12th month following the compliance date. If the compliance date 
occurs on any day other than the first day of a month, then the initial 
compliance period extends through the end of that month plus the next 12 
months. You must determine the mass of organic HAP emissions and mass of 
coating solids used each month and then calculate an organic HAP 
emission rate at the end of the initial compliance period. The initial 
compliance demonstration includes the calculations according to Sec. 
63.4551 and supporting documentation showing that during the initial 
compliance period the organic HAP emission rate was equal to or less 
than the applicable emission limit in Sec. 63.4490.



Sec. 63.4551  How do I demonstrate initial compliance with the emission
limitations?

    You may use the emission rate without add-on controls option for any 
individual coating operation, for any group of coating operations in the 
affected source, or for all the coating operations in the affected 
source. You must use either the compliant material option or the 
emission rate with add-on controls option for any coating operation in 
the affected source for which you do not use this option. To demonstrate 
initial compliance using the emission rate without add-on controls 
option, the coating operation or group of coating operations must meet 
the applicable emission limit in Sec. 63.4490, but is not required to 
meet the operating limits or work practice standards in Sec. Sec. 
63.4492 and 63.4493, respectively. You must conduct a separate initial 
compliance demonstration for each general use, TPO, automotive lamp, and 
assembled on-road vehicle coating operation unless you are demonstrating 
compliance with a predominant activity or facility-specific emission 
limit as provided in Sec. 63.4490(c). If you are demonstrating 
compliance with a predominant activity or facility-specific emission 
limit as provided in Sec. 63.4490(c), you must demonstrate that all 
coating operations included in the predominant activity determination or 
calculation of the facility-specific emission limit comply with that

[[Page 736]]

limit. You must meet all the requirements of this section. When 
calculating the organic HAP emission rate according to this section, do 
not include any coatings, thinners and/or other additives, or cleaning 
materials used on coating operations for which you use the compliant 
material option or the emission rate with add-on controls option. You do 
not need to redetermine the mass of organic HAP in coatings, thinners 
and/or other additives, or cleaning materials that have been reclaimed 
on-site (or reclaimed off-site if you have documentation showing that 
you received back the exact same materials that were sent off-site) and 
reused in the coating operation for which you use the emission rate 
without add-on controls option. If you use coatings, thinners and/or 
other additives, or cleaning materials that have been reclaimed on-site, 
the amount of each used in a month may be reduced by the amount of each 
that is reclaimed. That is, the amount used may be calculated as the 
amount consumed to account for materials that are reclaimed.
    (a) Determine the mass fraction of organic HAP for each material. 
Determine the mass fraction of organic HAP for each coating, thinner 
and/or other additive, and cleaning material used during each month 
according to the requirements in Sec. 63.4541(a).
    (b) Determine the mass fraction of coating solids. Determine the 
mass fraction of coating solids (kg (lb) of coating solids per kg (lb) 
of coating) for each coating used during each month according to the 
requirements in Sec. 63.4541(b).
    (c) Determine the density of each material. Determine the density of 
each liquid coating, thinner and/or other additive, and cleaning 
material used during each month from test results using ASTM Method 
D1475-98, ``Standard Test Method for Density of Liquid Coatings, Inks, 
and Related Products'' (incorporated by reference, see Sec. 63.14), 
information from the supplier or manufacturer of the material, or 
reference sources providing density or specific gravity data for pure 
materials. If there is disagreement between ASTM Method D1475-98 and 
other such information sources, the test results will take precedence 
unless, after consultation you demonstrate to the satisfaction of the 
enforcement agency that the formulation data are correct. If you 
purchase materials or monitor consumption by weight instead of volume, 
you do not need to determine material density. Instead, you may use the 
material weight in place of the combined terms for density and volume in 
Equations 1A, 1B, 1C, and 2 of this section.
    (d) Determine the volume of each material used. Determine the volume 
(liters) of each coating, thinner and/or other additive, and cleaning 
material used during each month by measurement or usage records. If you 
purchase materials or monitor consumption by weight instead of volume, 
you do not need to determine the volume of each material used. Instead, 
you may use the material weight in place of the combined terms for 
density and volume in Equations 1A, 1B, 1C, and 2 of this section.
    (e) Calculate the mass of organic HAP emissions. The mass of organic 
HAP emissions is the combined mass of organic HAP contained in all

n = Number of full or partial months in the compliance period (for the 
          initial compliance period, n equals 12 if the compliance date 
          falls on the first day of a month; otherwise n equals 13; for 
          all following compliance periods, n equals 12).

    (h) Compliance demonstration. The organic HAP emission rate for the 
initial compliance period calculated using Equation 3 of this section 
must be less than or equal to the applicable emission limit for each 
subcategory in Sec. 63.4490 or the predominant activity or facility-
specific emission limit allowed in Sec. 63.4490(c). You must keep all 
records as required by Sec. Sec. 63.4530 and 63.4531. As part of the 
notification of compliance status required by Sec. 63.4510, you must 
identify the coating operation(s) for which you used the emission rate 
without add-on controls option and submit a statement that the coating 
operation(s) was (were) in compliance with the emission limitations 
during the initial compliance period because the organic HAP emission 
rate was less than or equal to the applicable emission limit in Sec. 
63.4490, determined according to the procedures in this section.



Sec. 63.4552  How do I demonstrate continuous compliance with the
emission limitations?

    (a) To demonstrate continuous compliance, the organic HAP emission 
rate for each compliance period, determined according to Sec. 
63.4551(a) through (g), must be less than or equal to the applicable 
emission limit in Sec. 63.4490. A compliance period consists of 12 
months. Each month after the end of the initial compliance period 
described in Sec. 63.4550 is the end of a compliance period consisting 
of that month and the preceding 11 months. You must perform the 
calculations in Sec. 63.4551(a) through (g) on a monthly basis using 
data from the previous 12 months of operation. If you are complying with 
a facility-specific emission limit under Sec. 63.4490(c), you must also 
perform the calculation using Equation 1 in Sec. 63.4490(c)(2) on a 
monthly basis using the data from the previous 12 months of operation.
    (b) If the organic HAP emission rate for any 12-month compliance 
period exceeded the applicable emission limit in Sec. 63.4490, this is 
a deviation from the emission limitation for that compliance period and 
must be reported as specified in Sec. Sec. 63.4510(c)(6) and 
63.4520(a)(6).
    (c) As part of each semiannual compliance report required by Sec. 
63.4520, you must identify the coating operation(s) for which you used 
the emission rate without add-on controls option. If there were no 
deviations from the emission limitations, you must submit a statement 
that the coating operation(s) was (were) in compliance with the emission 
limitations during the reporting period because the organic HAP emission 
rate for each compliance period was less than or equal to the applicable 
emission limit in Sec. 63.4490, determined according to Sec. 
63.4551(a) through (g).
    (d) You must maintain records as specified in Sec. Sec. 63.4530 and 
63.4531.

   Compliance Requirements for the Emission Rate With Add-On Controls 
                                 Option



Sec. 63.4560  By what date must I conduct performance tests and other
initial compliance demonstrations?

    (a) New and reconstructed affected sources. For a new or 
reconstructed affected source, you must meet the requirements of 
paragraphs (a)(1) through (4) of this section.
    (1) All emission capture systems, add-on control devices, and CPMS 
must be installed and operating no later than the applicable compliance 
date specified in Sec. 63.4483. Except for solvent recovery systems for 
which you conduct liquid-liquid material balances according to Sec. 
63.4561(j), you must conduct a performance test of each capture system 
and add-on control device according to Sec. Sec. 63.4564, 63.4565, and 
63.4566 and establish the operating limits required by Sec. 63.4492 no 
later than 180 days after the applicable compliance date specified in 
Sec. 63.4483. For a solvent recovery system for which you conduct 
liquid-liquid material balances according to Sec. 63.4561(j), you must 
initiate the first material balance no later than the applicable 
compliance date specified in Sec. 63.4483.
    (2) You must develop and begin implementing the work practice plan 
required by Sec. 63.4493 no later than the compliance date specified in 
Sec. 63.4483.
    (3) You must complete the initial compliance demonstration for the 
initial compliance period according to the requirements of Sec. 
63.4561. The initial compliance period begins on the applicable 
compliance date specified in Sec. 63.4483 and ends on the last day of 
the 12th month following the compliance date. If the compliance date 
occurs on any day other than the first day of a month, then the initial 
compliance period extends through the end of that month plus the next 12 
months. You must determine the mass of organic HAP emissions and mass of 
coatings solids used each month and then calculate an organic HAP 
emission rate at the end of the initial compliance period. The initial 
compliance demonstration includes the results of emission capture system 
and add-on control device performance tests conducted according to 
Sec. Sec. 63.4564, 63.4565, and 63.4566; results of liquid-liquid 
material balances conducted according to Sec. 63.4561(j); calculations 
according to Sec. 63.4561 and supporting documentation showing that 
during the initial compliance period the organic HAP emission rate was 
equal to or less than the applicable emission limit in Sec. 63.4490; 
the operating limits established during the performance tests and the 
results of the continuous parameter monitoring required by Sec. 
63.4568; and documentation of whether you developed and implemented the

    (4) You do not need to comply with the operating limits for the 
emission capture system and add-on control device required by Sec. 
63.4492 until after you have completed the performance tests specified 
in paragraph (a)(1) of this section. Instead, you must maintain a log 
detailing the operation and maintenance of the emission capture system, 
add-on control device, and continuous parameter monitors during the 
period between the compliance date and the performance test. You must 
begin complying with the operating limits for your affected source on 
the date you complete the performance tests specified in paragraph 
(a)(1) of this section. The requirements in this paragraph (a)(4) do not 
apply to solvent recovery systems for which you conduct liquid-liquid 
material balances according to the requirements in Sec. 63.4561(j).
    (b) Existing affected sources. For an existing affected source, you 
must meet the requirements of paragraphs (b)(1) through (3) of this 
section.
    (1) All emission capture systems, add-on control devices, and CPMS 
must be installed and operating no later than the applicable compliance 
date specified in Sec. 63.4483. Except for solvent recovery systems for 
which you conduct liquid-liquid material balances according to Sec. 
63.4561(j), you must conduct a performance test of each capture system 
and add-on control device according to the procedures in Sec. Sec. 
63.4564, 63.4565, and 63.4566 and establish the operating limits 
required by Sec. 63.4492 no later than the compliance date specified in 
Sec. 63.4483. For a solvent recovery system for which you conduct

[[Page 740]]

liquid-liquid material balances according to Sec. 63.4561(j), you must 
initiate the first material balance no later than the compliance date 
specified in Sec. 63.4483.
    (2) You must develop and begin implementing the work practice plan 
required by Sec. 63.4493 no later than the compliance date specified in 
Sec. 63.4483.
    (3) You must complete the initial compliance demonstration for the 
initial compliance period according to the requirements of Sec. 
63.4561. The initial compliance period begins on the applicable 
compliance date specified in Sec. 63.4483 and ends on the last day of 
the 12th month following the compliance date. If the compliance date 
occurs on any day other than the first day of a month, then the initial 
compliance period extends through the end of that month plus the next 12 
months. You must determine the mass of organic HAP emissions and mass of 
coatings solids used each month and then calculate an organic HAP 
emission rate at the end of the initial compliance period. The initial 
compliance demonstration includes the results of emission capture system 
and add-on control device performance tests conducted according to 
Sec. Sec. 63.4564, 63.4565, and 63.4566; results of liquid-liquid 
material balances conducted according to Sec. 63.4561(j); calculations 
according to Sec. 63.4561 and supporting documentation showing that 
during the initial compliance period the organic HAP emission rate was 
equal to or less than the applicable emission limit in Sec. 63.4490; 
the operating limits established during the performance tests and the 
results of the continuous parameter monitoring required by Sec. 
63.4568; and documentation of whether you developed and implemented the 
work practice plan required by Sec. 63.4493.
    (c) You are not required to conduct an initial performance test to 
determine capture efficiency or destruction efficiency of a capture 
system or control device if you receive approval to use the results of a 
performance test that has been previously conducted on that capture 
system or control device. Any such previous tests must meet the 
conditions described in paragraphs (c)(1) through (3) of this section.
    (1) The previous test must have been conducted using the methods and 
conditions specified in this subpart.
    (2) Either no process or equipment changes must have been made since 
the previous test was performed, or the owner or operator must be able 
to demonstrate that the results of the performance test, with or without 
adjustments, reliably demonstrate compliance despite process or 
equipment changes.
    (3) Either the required operating parameters were established in the 
previous test or sufficient data were collected in the previous test to 
establish the required operating parameters.



Sec. 63.4561  How do I demonstrate initial compliance?

    (a) You may use the emission rate with add-on controls option for 
any coating operation, for any group of coating operations in the 
affected source, or for all of the coating operations in the affected 
source. You may include both controlled and uncontrolled coating 
operations in a group for which you use this option. You must use either 
the compliant material option or the emission rate without add-on 
controls option for any coating operation in the affected source for 
which you do not use the emission rate with add-on controls option. To 
demonstrate initial compliance, the coating operation(s) for which you 
use the emission rate with add-on controls option must meet the 
applicable emission limitations in Sec. Sec. 63.4490, 63.4492, and 
63.4493. You must conduct a separate initial compliance demonstration 
for each general use, TPO, automotive lamp, and assembled on-road 
vehicle coating operation, unless you are demonstrating compliance with 
a predominant activity or facility-specific emission limit as provided 
in Sec. 63.4490(c). If you are demonstrating compliance with a 
predominant activity or facility-specific emission limit as provided in 
Sec. 63.4490(c), you must demonstrate that all coating operations 
included in the predominant activity determination or calculation of the 
facility-specific emission limit comply with that limit. You must meet 
all the requirements of this section. When calculating

[[Page 741]]

the organic HAP emission rate according to this section, do not include 
any coatings, thinners and/or other additives, or cleaning materials 
used on coating operations for which you use the compliant material 
option or the emission rate without add-on controls option. You do not 
need to redetermine the mass of organic HAP in coatings, thinners and/or 
other additives, or cleaning materials that have been reclaimed onsite 
(or reclaimed off-site if you have documentation showing that you 
received back the exact same materials that were sent off-site) and 
reused in the coatings operation(s) for which you use the emission rate 
with add-on controls option. If you use coatings, thinners and/or other 
additives, or cleaning materials that have been reclaimed on-site, the 
amount of each used in a month may be reduced by the amount of each that 
is reclaimed. That is, the amount used may be calculated as the amount 
consumed to account for materials that are reclaimed.
    (b) Compliance with operating limits. Except as provided in Sec. 
63.4560(a)(4), and except for solvent recovery systems for which you 
conduct liquid-liquid material balances according to the requirements of 
paragraph (j) of this section, you must establish and demonstrate 
continuous compliance during the initial compliance period with the 
operating limits required by Sec. 63.4492, using the procedures 
specified in Sec. Sec. 63.4567 and 63.4568.
    (c) Compliance with work practice requirements. You must develop, 
implement, and document your implementation of the work practice plan 
required by Sec. 63.4493 during the initial compliance period, as 
specified in Sec. 63.4530.
    (d) Compliance with emission limits. You must follow the procedures 
in paragraphs (e) through (n) of this section to demonstrate compliance 
with the applicable emission limit in Sec. 63.4490 for each affected 
source in each subcategory.
    (e) Determine the mass fraction of organic HAP, density, volume 
used, and mass fraction of coating solids. Follow the procedures 
specified in Sec. 63.4551(a) through (d) to determine the mass fraction 
of organic HAP, density, and volume of each coating, thinner and/or 
other additive, and cleaning material used during each month; and the 
mass fraction of coating solids for each coating used during each month.
    (f) Calculate the total mass of organic HAP emissions before add-on 
controls. Using Equation 1 of Sec. 63.4551, calculate the total mass of 
organic HAP emissions before add-on controls from all coatings, thinners 
and/or other additives, and cleaning materials used during each month in 
the coating operation or group of coating operations for which you use 
the emission rate with add-on controls option.
    (g) Calculate the organic HAP emission reduction for each controlled 
coating operation. Determine the mass of organic HAP emissions reduced 
for each controlled coating operation during each month. The emission 
reduction determination quantifies the total organic HAP emissions that 
pass through the emission capture system and are destroyed or removed by 
the add-on control device. Use the procedures in paragraph (h) of this 
section to calculate the mass of organic HAP emission reduction for each 
controlled coating operation using an emission capture system and add-on 
control device other than a solvent recovery system for which you 
conduct liquid-liquid material balances. For each controlled coating 
operation using a solvent recovery system for which you conduct a 
liquid-liquid material balance, use the procedures in paragraph (j) of 
this section to calculate the organic HAP emission reduction.
    (h) Calculate the organic HAP emission reduction for each controlled 
coating operation not using liquid-liquid material balance. Use Equation 
1 of this section to calculate the organic HAP emission reduction for 
each controlled coating operation using an emission capture system and 
add-on control device other than a solvent recovery system for which you 
conduct liquid-liquid material balances. The calculation applies the 
emission capture system efficiency and add-on control device efficiency 
to the mass of organic HAP contained in the coatings, thinners and/or 
other additives, and cleaning materials that are used in the coating 
operation served by the emission capture system and add-on control 
device during each month. You must assume zero efficiency for

[[Page 742]]

the emission capture system and add-on control device for any period of 
time a deviation specified in Sec. 63.4563(c) or (d) occurs in the 
controlled coating operation, including a deviation during a period of 
startup, shutdown, or malfunction, unless you have other data indicating 
the actual efficiency of the emission capture system and add-on control 
device and the use of these data is approved by the Administrator. 
Equation 1 of this section treats the materials used during such a 
deviation as if they were used on an uncontrolled coating operation for 
the time period of the deviation.

controlled coating operation using a solvent recovery system for which 
you conduct liquid-liquid material balances, calculate the organic HAP 
emission reduction by applying the volatile organic matter collection 
and recovery efficiency to the mass of organic HAP contained in the 
coatings, thinners and/or other additives, and cleaning materials that 
are used in the coating operation controlled by the solvent recovery 
system during each month. Perform a liquid-liquid material balance for

that indicates the cumulative amount of volatile organic matter 
recovered by the solvent recovery system each month. The device must be 
initially certified by the manufacturer to be accurate to within 2.0 percent of the mass of volatile organic matter 
recovered.

60, appendix A, or an EPA approved alternative method, or you may use 
information provided by the manufacturer or supplier of the coating. In 
the event of any inconsistency between information provided by the 
manufacturer or supplier and the results of Method 24 of 40 CFR part 60, 
appendix A, or an approved alternative method, the test method results 
will take precedence unless, after consultation you demonstrate to the 
satisfaction of the enforcement agency that the formulation data are 
correct.

records as required by Sec. Sec. 63.4530 and 63.4531. As part of the 
notification of compliance status required by Sec. 63.4510, you must 
identify the coating operation(s) for which you used the emission rate 
with add-on controls option and submit a statement that the coating 
operation(s) was (were) in compliance with the emission limitations 
during the initial compliance period because the organic HAP emission 
rate was less than or equal to the applicable emission limit in Sec. 
63.4490, and you achieved the operating limits required by Sec. 63.4492 
and the work practice standards required by Sec. 63.4493.



Sec. 63.4562  [Reserved]



Sec. 63.4563  How do I demonstrate continuous compliance with the
emission limitations?

    (a) To demonstrate continuous compliance with the applicable 
emission limit in Sec. 63.4490, the organic HAP emission rate for each 
compliance period, determined according to the procedures in Sec. 
63.4561, must be equal to or less than the applicable emission limit

[[Page 747]]

in Sec. 63.4490. A compliance period consists of 12 months. Each month 
after the end of the initial compliance period described in Sec. 
63.4560 is the end of a compliance period consisting of that month and 
the preceding 11 months. You must perform the calculations in Sec. 
63.4561 on a monthly basis using data from the previous 12 months of 
operation. If you are complying with a facility-specific emission limit 
under Sec. 63.4490(c), you must also perform the calculation using 
Equation 1 in Sec. 63.4490(c)(2) on a monthly basis using the data from 
the previous 12 months of operation.
    (b) If the organic HAP emission rate for any 12-month compliance 
period exceeded the applicable emission limit in Sec. 63.4490, this is 
a deviation from the emission limitation for that compliance period that 
must be reported as specified in Sec. Sec. 63.4510(c)(6) and 
63.4520(a)(7).
    (c) You must demonstrate continuous compliance with each operating 
limit required by Sec. 63.4492 that applies to you, as specified in 
Table 1 to this subpart, when the coating line is in operation.
    (1) If an operating parameter is out of the allowed range specified 
in Table 1 to this subpart, this is a deviation from the operating limit 
that must be reported as specified in Sec. Sec. 63.4510(c)(6) and 
63.4520(a)(7).
    (2) If an operating parameter deviates from the operating limit 
specified in Table 1 to this subpart, then you must assume that the 
emission capture system and add-on control device were achieving zero 
efficiency during the time period of the deviation, unless you have 
other data indicating the actual efficiency of the emission capture 
system and add-on control device and the use of these data is approved 
by the Administrator.
    (d) You must meet the requirements for bypass lines in Sec. 
63.4568(b) for controlled coating operations for which you do not 
conduct liquid-liquid material balances. If any bypass line is opened 
and emissions are diverted to the atmosphere when the coating operation 
is running, this is a deviation that must be reported as specified in 
Sec. Sec. 63.4510(c)(6) and 63.4520(a)(7). For the purposes of 
completing the compliance calculations specified in Sec. Sec. 
63.4561(h), you must treat the materials used during a deviation on a 
controlled coating operation as if they were used on an uncontrolled 
coating operation for the time period of the deviation as indicated in 
Equation 1 of Sec. 63.4561.
    (e) You must demonstrate continuous compliance with the work 
practice standards in Sec. 63.4493. If you did not develop a work 
practice plan, or you did not implement the plan, or you did not keep 
the records required by Sec. 63.4530(i)(8), this is a deviation from 
the work practice standards that must be reported as specified in 
Sec. Sec. 63.4510(c)(6) and 63.4520(a)(7).
    (f) As part of each semiannual compliance report required in Sec. 
63.4520, you must identify the coating operation(s) for which you used 
the emission rate with add-on controls option. If there were no 
deviations from the emission limitations, submit a statement that you 
were in compliance with the emission limitations during the reporting 
period because the organic HAP emission rate for each compliance period 
was less than or equal to the applicable emission limit in Sec. 
63.4490, and you achieved the operating limits required by Sec. 63.4492 
and the work practice standards required by Sec. 63.4493 during each 
compliance period.
    (g)-(i) [Reserved]
    (j) You must maintain records as specified in Sec. Sec. 63.4530 and 
63.4531.

[69 FR 20990, Apr. 19, 2004, as amended at 71 FR 20465, Apr. 20, 2006]



Sec. 63.4564  What are the general requirements for performance tests?

    (a) You must conduct each performance test required by Sec. 63.4560 
according to the requirements in Sec. 63.7(e)(1) and under the 
conditions in this section, unless you obtain a waiver of the 
performance test according to the provisions in Sec. 63.7(h).
    (1) Representative coating operation operating conditions. You must 
conduct the performance test under representative operating conditions 
for the coating operation. Operations during periods of startup, 
shutdown, or malfunction and during periods of nonoperation do not 
constitute representative conditions. You must record the process 
information that is necessary to document operating conditions during

[[Page 748]]

the test and explain why the conditions represent normal operation.
    (2) Representative emission capture system and add-on control device 
operating conditions. You must conduct the performance test when the 
emission capture system and add-on control device are operating at a 
representative flow rate, and the add-on control device is operating at 
a representative inlet concentration. You must record information that 
is necessary to document emission capture system and add-on control 
device operating conditions during the test and explain why the 
conditions represent normal operation.
    (b) You must conduct each performance test of an emission capture 
system according to the requirements in Sec. 63.4565. You must conduct 
each performance test of an add-on control device according to the 
requirements in Sec. 63.4566.



Sec. 63.4565  How do I determine the emission capture system efficiency?

    You must use the procedures and test methods in this section to 
determine capture efficiency as part of the performance test required by 
Sec. 63.4560.
    (a) Assuming 100 percent capture efficiency. You may assume the 
capture system efficiency is 100 percent if both of the conditions in 
paragraphs (a)(1) and (2) of this section are met:
    (1) The capture system meets the criteria in Method 204 of appendix 
M to 40 CFR part 51 for a PTE and directs all the exhaust gases from the 
enclosure to an add-on control device.
    (2) All coatings, thinners and/or other additives, and cleaning 
materials used in the coating operation are applied within the capture 
system; coating solvent flash-off, curing, and drying occurs within the 
capture system; and the removal or evaporation of cleaning materials 
from the surfaces they are applied to occurs within the capture system. 
For example, this criterion is not met if parts enter the open shop 
environment when being moved between a spray booth and a curing oven.
    (b) Measuring capture efficiency. If the capture system does not 
meet both of the criteria in paragraphs (a)(1) and (2) of this section, 
then you must use one of the three protocols described in paragraphs 
(c), (d), and (e) of this section to measure capture efficiency. The 
capture efficiency measurements use TVH capture efficiency as a 
surrogate for organic HAP capture efficiency. For the protocols in 
paragraphs (c) and (d) of this section, the capture efficiency 
measurement must consist of three test runs. Each test run must be at 
least 3 hours duration or the length of a production run, whichever is 
longer, up to 8 hours. For the purposes of this test, a production run 
means the time required for a single part to go from the beginning to 
the end of the production, which includes surface preparation activities 
and drying and curing time.
    (c) Liquid-to-uncaptured-gas protocol using a temporary total 
enclosure or building enclosure. The liquid-to-uncaptured-gas protocol 
compares the mass of liquid TVH in materials used in the coating 
operation to the mass of TVH emissions not captured by the emission 
capture system. Use a temporary total enclosure or a building enclosure 
and the procedures in paragraphs (c)(1) through (6) of this section to 
measure emission capture system efficiency using the liquid-to-
uncaptured-gas protocol.
    (1) Either use a building enclosure or construct an enclosure around 
the coating operation where coatings, thinners and/or other additives, 
and cleaning materials are applied, and all areas where emissions from 
these applied coatings and materials subsequently occur, such as flash-
off, curing, and drying areas. The areas of the coating operation where 
capture devices collect emissions for routing to an add-on control 
device, such as the entrance and exit areas of an oven or spray booth, 
must also be inside the enclosure. The enclosure must meet the 
applicable definition of a temporary total enclosure or building 
enclosure in Method 204 of appendix M to 40 CFR part 51.
    (2) Use Method 204A or 204F of appendix M to 40 CFR part 51 to 
determine the mass fraction of TVH liquid input from each coating, 
thinner and/or other additive, and cleaning material used in the coating 
operation during each capture efficiency test run. To make the 
determination, substitute TVH for each occurrence of the term volatile

[[Page 749]]

organic compounds (VOC) in the methods.
    (3) Use Equation 1 of this section to calculate the total mass of 
TVH liquid input from all the coatings, thinners and/or other additives, 
and cleaning materials used in the coating operation during each capture 
efficiency test run:
[GRAPHIC] [TIFF OMITTED] TR19AP04.022

Where:

TVHused = Mass of liquid TVH in materials used in the coating 
          operation during the capture efficiency test run, kg.
TVHi = Mass fraction of TVH in coating, thinner and/or other 
          additive, or cleaning material, i, that is used in the coating 
          operation during the capture efficiency test run, kg TVH per 
          kg material.
Voli = Total volume of coating, thinner and/or other 
          additive, or cleaning material, i, used in the coating 
          operation during the capture efficiency test run, liters.
Di = Density of coating, thinner and/or other additive, or 
          cleaning material, i, kg material per liter material.
n = Number of different coatings, thinners and/or other additives, and 
          cleaning materials used in the coating operation during the 
          capture efficiency test run.

    (4) Use Method 204D or 204E of appendix M to 40 CFR part 51 to 
measure the total mass, kg, of TVH emissions that are not captured by 
the emission capture system. They are measured as they exit the 
temporary total enclosure or building enclosure during each capture 
efficiency test run. To make the measurement, substitute TVH for each 
occurrence of the term VOC in the methods.
    (i) Use Method 204D of appendix M to 40 CFR part 51 if the enclosure 
is a temporary total enclosure.
    (ii) Use Method 204E of appendix M to 40 CFR 51 if the enclosure is 
a building enclosure. During the capture efficiency measurement, all 
organic compound emitting operations inside the building enclosure, 
other than the coating operation for which capture efficiency is being 
determined, must be shut down, but all fans and blowers must be 
operating normally.
    (5) For each capture efficiency test run, determine the percent 
capture efficiency of the emission capture system using Equation 2 of 
this section:
[GRAPHIC] [TIFF OMITTED] TR19AP04.023

Where:

CE = Capture efficiency of the emission capture system vented to the 
          add-on control device, percent.
TVHused = Total mass of TVH liquid input used in the coating 
          operation during the capture efficiency test run, kg.
TVHuncaptured = Total mass of TVH that is not captured by the 
          emission capture system and that exits from the temporary 
          total enclosure or building enclosure during the capture 
          efficiency test run, kg.

    (6) Determine the capture efficiency of the emission capture system 
as the average of the capture efficiencies measured in the three test 
runs.
    (d) Gas-to-gas protocol using a temporary total enclosure or a 
building enclosure. The gas-to-gas protocol compares the mass of TVH 
emissions captured by the emission capture system to the mass of TVH 
emissions not captured. Use a temporary total enclosure or a building 
enclosure and the procedures in paragraphs (d)(1) through (5) of this 
section to measure emission capture system efficiency using the gas-to-
gas protocol.
    (1) Either use a building enclosure or construct an enclosure around 
the coating operation where coatings, thinners and/or other additives, 
and cleaning materials are applied, and all areas where emissions from 
these applied coatings and materials subsequently occur, such as flash-
off, curing, and drying areas. The areas of the coating operation where 
capture devices collect emissions generated by the coating operation for 
routing to an add-on control device, such as the entrance and exit areas 
of an oven or a spray booth,

[[Page 750]]

must also be inside the enclosure. The enclosure must meet the 
applicable definition of a temporary total enclosure or building 
enclosure in Method 204 of appendix M to 40 CFR part 51.
    (2) Use Method 204B or 204C of appendix M to 40 CFR part 51 to 
measure the total mass, kg, of TVH emissions captured by the emission 
capture system during each capture efficiency test run as measured at 
the inlet to the add-on control device. To make the measurement, 
substitute TVH for each occurrence of the term VOC in the methods.
    (i) The sampling points for the Method 204B or 204C measurement must 
be upstream from the add-on control device and must represent total 
emissions routed from the capture system and entering the add-on control 
device.
    (ii) If multiple emission streams from the capture system enter the 
add-on control device without a single common duct, then the emissions 
entering the add-on control device must be simultaneously measured in 
each duct and the total emissions entering the add-on control device 
must be determined.
    (3) Use Method 204D or 204E of appendix M to 40 CFR part 51 to 
measure the total mass, kg, of TVH emissions that are not captured by 
the emission capture system; they are measured as they exit the 
temporary total enclosure or building enclosure during each capture 
efficiency test run. To make the measurement, substitute TVH for each 
occurrence of the term VOC in the methods.
    (i) Use Method 204D of appendix M to 40 CFR part 51 if the enclosure 
is a temporary total enclosure.
    (ii) Use Method 204E of appendix M to 40 CFR part 51 if the 
enclosure is a building enclosure. During the capture efficiency 
measurement, all organic compound emitting operations inside the 
building enclosure, other than the coating operation for which capture 
efficiency is being determined, must be shut down, but all fans and 
blowers must be operating normally.
    (4) For each capture efficiency test run, determine the percent 
capture efficiency of the emission capture system using Equation 3 of 
this section:
[GRAPHIC] [TIFF OMITTED] TR19AP04.024

Where:

CE = Capture efficiency of the emission capture system vented to the 
          add-on control device, percent.
TVHcaptured = Total mass of TVH captured by the emission 
          capture system as measured at the inlet to the add-on control 
          device during the emission capture efficiency test run, kg.
TVHuncaptured = Total mass of TVH that is not captured by the 
          emission capture system and that exits from the temporary 
          total enclosure or building enclosure during the capture 
          efficiency test run, kg.

    (5) Determine the capture efficiency of the emission capture system 
as the average of the capture efficiencies measured in the three test 
runs.
    (e) Alternative capture efficiency protocol. As an alternative to 
the procedures specified in paragraphs (c) and (d) of this section and 
subject to the approval of the Administrator, you may determine capture 
efficiency using any other capture efficiency protocol and test methods 
that satisfy the criteria of either the DQO or LCL approach as described 
in appendix A to subpart KK of this part.



Sec. 63.4566  How do I determine the add-on control device emission
destruction or removal efficiency?

    You must use the procedures and test methods in this section to 
determine the add-on control device emission destruction or removal 
efficiency as part of the performance test required by Sec. 63.4560. 
You must conduct three test runs as specified in Sec. 63.7(e)(3) and 
each test run must last at least 1 hour.
    (a) For all types of add-on control devices, use the test methods 
specified in paragraphs (a)(1) through (5) of this section.

[[Page 751]]

    (1) Use Method 1 or 1A of appendix A to 40 CFR part 60, as 
appropriate, to select sampling sites and velocity traverse points.
    (2) Use Method 2, 2A, 2C, 2D, 2F, or 2G of appendix A to 40 CFR part 
60, as appropriate, to measure gas volumetric flow rate.
    (3) Use Method 3, 3A, or 3B of appendix A to 40 CFR part 60, as 
appropriate, for gas analysis to determine dry molecular weight.
    (4) Use Method 4 of appendix A to 40 CFR part 60, to determine stack 
gas moisture.
    (5) Methods for determining gas volumetric flow rate, dry molecular 
weight, and stack gas moisture must be performed, as applicable, during 
each test run.
    (b) Measure total gaseous organic mass emissions as carbon at the 
inlet and outlet of the add-on control device simultaneously, using 
either Method 25 or 25A of appendix A to 40 CFR part 60.
    (1) Use Method 25 if the add-on control device is an oxidizer and 
you expect the total gaseous organic concentration as carbon to be more 
than 50 parts per million (ppm) at the control device outlet.
    (2) Use Method 25A if the add-on control device is an oxidizer and 
you expect the total gaseous organic concentration as carbon to be 50 
ppm or less at the control device outlet.
    (3) Use Method 25A if the add-on control device is not an oxidizer.
    (c) If two or more add-on control devices are used for the same 
emission stream, then you must measure emissions at the outlet to the 
atmosphere of each device. For example, if one add-on control device is 
a concentrator with an outlet to the atmosphere for the high-volume 
dilute stream that has been treated by the concentrator, and a second 
add-on control device is an oxidizer with an outlet to the atmosphere 
for the low-volume concentrated stream that is treated with the 
oxidizer, you must measure emissions at the outlet of the oxidizer and 
the high volume dilute stream outlet of the concentrator.
    (d) For each test run, determine the total gaseous organic emissions 
mass flow rates for the inlet and the outlet of the add-on control 
device, using Equation 1 of this section. If there is more than one 
inlet or outlet to the add-on control device, you must calculate the 
total gaseous organic mass flow rate using Equation 1 of this section 
for each inlet and each outlet and then total all of the inlet emissions 
and total all of the outlet emissions:
[GRAPHIC] [TIFF OMITTED] TR19AP04.025

Where:

Mf = Total gaseous organic emissions mass flow rate, kg/per 
          hour (h).
Cc = Concentration of organic compounds as carbon in the vent 
          gas, as determined by Method 25 or Method 25A, parts per 
          million by volume (ppmv), dry basis.
Qsd = Volumetric flow rate of gases entering or exiting the 
          add-on control device, as determined by Method 2, 2A, 2C, 2D, 
          2F, or 2G, dry standard cubic meters/hour (dscm/h).
0.0416 = Conversion factor for molar volume, kg-moles per cubic meter 
          (mol/m\3\) (@ 293 Kelvin (K) and 760 millimeters of mercury 
          (mmHg)).

    (e) For each test run, determine the add-on control device organic 
emissions destruction or removal efficiency, using Equation 2 of this 
section:
[GRAPHIC] [TIFF OMITTED] TR19AP04.026

Where:

DRE = Organic emissions destruction or removal efficiency of the add-on 
          control device, percent.
Mfi = Total gaseous organic emissions mass flow rate at the 
          inlet(s) to the add-on control device, using Equation 1 of 
          this section, kg/h.
Mfo = Total gaseous organic emissions mass flow rate at the 
          outlet(s) of the add-on control device, using Equation 1 of 
          this section, kg/h.

    (f) Determine the emission destruction or removal efficiency of the 
add-on control device as the average of the efficiencies determined in 
the three test runs and calculated in Equation 2 of this section.



Sec. 63.4567  How do I establish the emission capture system and
add-on control device operating limits during the performance test?

    During the performance test required by Sec. 63.4560 and described 
in Sec. Sec. 63.4564, 63.4565, and 63.4566, you must establish

[[Page 752]]

the operating limits required by Sec. 63.4492 according to this 
section, unless you have received approval for alternative monitoring 
and operating limits under Sec. 63.8(f) as specified in Sec. 63.4492.
    (a) Thermal oxidizers. If your add-on control device is a thermal 
oxidizer, establish the operating limits according to paragraphs (a)(1) 
and (2) of this section.
    (1) During the performance test, you must monitor and record the 
combustion temperature at least once every 15 minutes during each of the 
three test runs. You must monitor the temperature in the firebox of the 
thermal oxidizer or immediately downstream of the firebox before any 
substantial heat exchange occurs.
    (2) Use the data collected during the performance test to calculate 
and record the average combustion temperature maintained during the 
performance test. This average combustion temperature is the minimum 
operating limit for your thermal oxidizer.
    (b) Catalytic oxidizers. If your add-on control device is a 
catalytic oxidizer, establish the operating limits according to either 
paragraphs (b)(1) and (2) or paragraphs (b)(3) and (4) of this section.
    (1) During the performance test, you must monitor and record the 
temperature just before the catalyst bed and the temperature difference 
across the catalyst bed at least once every 15 minutes during each of 
the three test runs.
    (2) Use the data collected during the performance test to calculate 
and record the average temperature just before the catalyst bed and the 
average temperature difference across the catalyst bed maintained during 
the performance test. These are the minimum operating limits for your 
catalytic oxidizer.
    (3) You must monitor the temperature at the inlet to the catalyst 
bed and implement a site-specific inspection and maintenance plan for 
your catalytic oxidizer as specified in paragraph (b)(4) of this 
section. During the performance test, you must monitor and record the 
temperature just before the catalyst bed at least once every 15 minutes 
during each of the three test runs. Use the data collected during the 
performance test to calculate and record the average temperature just 
before the catalyst bed during the performance test. This is the minimum 
operating limit for your catalytic oxidizer.
    (4) You must develop and implement an inspection and maintenance 
plan for your catalytic oxidizer(s) for which you elect to monitor 
according to paragraph (b)(3) of this section. The plan must address, at 
a minimum, the elements specified in paragraphs (b)(4)(i) through (iii) 
of this section.
    (i) Annual sampling and analysis of the catalyst activity (i.e., 
conversion efficiency) following the manufacturer's or catalyst 
supplier's recommended procedures. If problems are found during the 
catalyst activity test, you must replace the catalyst bed or take other 
corrective action consistent with the manufacturer's recommendations.
    (ii) Monthly external inspection of the catalytic oxidizer system, 
including the burner assembly and fuel supply lines for problems and, as 
necessary, adjust the equipment to assure proper air-to-fuel mixtures.
    (iii) Annual internal inspection of the catalyst bed to check for 
channeling, abrasion, and settling. If problems are found during the 
annual internal inspection of the catalyst, you must replace the 
catalyst bed or take other corrective action consistent with the 
manufacturer's recommendations. If the catalyst bed is replaced and is 
not of like or better kind and quality as the old catalyst then you must 
conduct a new performance test to determine destruction efficiency 
according to Sec. 63.4566. If a catalyst bed is replaced and the 
replacement catalyst is of like or better kind and quality as the old 
catalyst, then a new performance test to determine destruction 
efficiency is not required and you may continue to use the previously 
established operating limits for that catalytic oxidizer.
    (c) Regenerative carbon adsorbers. If your add-on control device is 
a regenerative carbon adsorber, establish the operating limits according 
to paragraphs (c)(1) and (2) of this section.
    (1) You must monitor and record the total regeneration desorbing gas 
(e.g., steam or nitrogen) mass flow for each

[[Page 753]]

regeneration cycle, and the carbon bed temperature after each carbon bed 
regeneration and cooling cycle for the regeneration cycle either 
immediately preceding or immediately following the performance test.
    (2) The operating limits for your regenerative carbon adsorber are 
the minimum total desorbing gas mass flow recorded during the 
regeneration cycle and the maximum carbon bed temperature recorded after 
the cooling cycle.
    (d) Condensers. If your add-on control device is a condenser, 
establish the operating limits according to paragraphs (d)(1) and (2) of 
this section.
    (1) During the performance test, you must monitor and record the 
condenser outlet (product side) gas temperature at least once every 15 
minutes during each of the three test runs.
    (2) Use the data collected during the performance test to calculate 
and record the average condenser outlet (product side) gas temperature 
maintained during the performance test. This average condenser outlet 
gas temperature is the maximum operating limit for your condenser.
    (e) Concentrators. If your add-on control device includes a 
concentrator, you must establish operating limits for the concentrator 
according to paragraphs (e)(1) through (4) of this section.
    (1) During the performance test, you must monitor and record the 
desorption concentrate stream gas temperature at least once every 15 
minutes during each of the three runs of the performance test.
    (2) Use the data collected during the performance test to calculate 
and record the average temperature. This is the minimum operating limit 
for the desorption concentrate gas stream temperature.
    (3) During the performance test, you must monitor and record the 
pressure drop of the dilute stream across the concentrator at least once 
every 15 minutes during each of the three runs of the performance test.
    (4) Use the data collected during the performance test to calculate 
and record the average pressure drop. This is the minimum operating 
limit for the dilute stream across the concentrator.
    (f) Emission capture systems. For each capture device that is not 
part of a PTE that meets the criteria of Sec. 63.4565(a), establish an 
operating limit for either the gas volumetric flow rate or duct static 
pressure, as specified in paragraphs (f)(1) and (2) of this section. The 
operating limit for a PTE is specified in Table 1 to this subpart.
    (1) During the capture efficiency determination required by Sec. 
63.4560 and described in Sec. Sec. 63.4564 and 63.4565, you must 
monitor and record either the gas volumetric flow rate or the duct 
static pressure for each separate capture device in your emission 
capture system at least once every 15 minutes during each of the three 
test runs at a point in the duct between the capture device and the add-
on control device inlet.
    (2) Calculate and record the average gas volumetric flow rate or 
duct static pressure for the three test runs for each capture device. 
This average gas volumetric flow rate or duct static pressure is the 
minimum operating limit for that specific capture device.



Sec. 63.4568  What are the requirements for continuous parameter 
monitoring system installation, operation, and maintenance?

    (a) General. You must install, operate, and maintain each CPMS 
specified in paragraphs (c), (e), (f), and (g) of this section according 
to paragraphs (a)(1) through (6) of this section. You must install, 
operate, and maintain each CPMS specified in paragraphs (b) and (d) of 
this section according to paragraphs (a)(3) through (5) of this section.
    (1) The CPMS must complete a minimum of one cycle of operation for 
each successive 15-minute period. You must have a minimum of four 
equally spaced successive cycles of CPMS operation in 1 hour.
    (2) You must determine the average of all recorded readings for each 
successive 3-hour period of the emission capture system and add-on 
control device operation.
    (3) You must record the results of each inspection, calibration, and 
validation check of the CPMS.
    (4) You must maintain the CPMS at all times and have available 
necessary parts for routine repairs of the monitoring equipment.

[[Page 754]]

    (5) You must operate the CPMS and collect emission capture system 
and add-on control device parameter data at all times that a controlled 
coating operation is operating, except during monitoring malfunctions, 
associated repairs, and required quality assurance or control activities 
(including, if applicable, calibration checks and required zero and span 
adjustments).
    (6) You must not use emission capture system or add-on control 
device parameter data recorded during monitoring malfunctions, 
associated repairs, out-of-control periods, or required quality 
assurance or control activities when calculating data averages. You must 
use all the data collected during all other periods in calculating the 
data averages for determining compliance with the emission capture 
system and add-on control device operating limits.
    (7) A monitoring malfunction is any sudden, infrequent, not 
reasonably preventable failure of the CPMS to provide valid data. 
Monitoring failures that are caused in part by poor maintenance or 
careless operation are not malfunctions. Any period for which the 
monitoring system is out-of-control and data are not available for 
required calculations is a deviation from the monitoring requirements.
    (b) Capture system bypass line. You must meet the requirements of 
paragraphs (b)(1) and (2) of this section for each emission capture 
system that contains bypass lines that could divert emissions away from 
the add-on control device to the atmosphere.
    (1) You must monitor or secure the valve or closure mechanism 
controlling the bypass line in a nondiverting position in such a way 
that the valve or closure mechanism cannot be opened without creating a 
record that the valve was opened. The method used to monitor or secure 
the valve or closure mechanism must meet one of the requirements 
specified in paragraphs (b)(1)(i) through (v) of this section.
    (i) Flow control position indicator. Install, calibrate, maintain, 
and operate according to the manufacturer's specifications a flow 
control position indicator that takes a reading at least once every 15 
minutes and provides a record indicating whether the emissions are 
directed to the add-on control device or diverted from the add-on 
control device. The time of occurrence and flow control position must be 
recorded, as well as every time the flow direction is changed. The flow 
control position indicator must be installed at the entrance to any 
bypass line that could divert the emissions away from the add-on control 
device to the atmosphere.
    (ii) Car-seal or lock-and-key valve closures. Secure any bypass line 
valve in the closed position with a car-seal or a lock-and-key type 
configuration. You must visually inspect the seal or closure mechanism 
at least once every month to ensure that the valve is maintained in the 
closed position, and the emissions are not diverted away from the add-on 
control device to the atmosphere.
    (iii) Valve closure monitoring. Ensure that any bypass line valve is 
in the closed (nondiverting) position through monitoring of valve 
position at least once every 15 minutes. You must inspect the monitoring 
system at least once every month to verify that the monitor will 
indicate valve position.
    (iv) Automatic shutdown system. Use an automatic shutdown system in 
which the coating operation is stopped when flow is diverted by the 
bypass line away from the add-on control device to the atmosphere when 
the coating operation is running. You must inspect the automatic 
shutdown system at least once every month to verify that it will detect 
diversions of flow and shut down the coating operation.
    (v) Flow direction indicator. Install, calibrate, maintain, and 
operate according to the manufacturer's specifications a flow direction 
indicator that takes a reading at least once every 15 minutes and 
provides a record indicating whether the emissions are directed to the 
add-on control device or diverted from the add-on control device. Each 
time the flow direction changes, the next reading of the time of 
occurrence and flow direction must be recorded. The flow direction 
indicator must be installed in each bypass line or air makeup supply 
line that could divert the emissions away from the add-on control device 
to the atmosphere.

[[Page 755]]

    (2) If any bypass line is opened, you must include a description of 
why the bypass line was opened and the length of time it remained open 
in the semiannual compliance reports required in Sec. 63.4520.
    (c) Thermal oxidizers and catalytic oxidizers. If you are using a 
thermal oxidizer or catalytic oxidizer as an add-on control device 
(including those used with concentrators or with carbon adsorbers to 
treat desorbed concentrate streams), you must comply with the 
requirements in paragraphs (c)(1) through (3) of this section:
    (1) For a thermal oxidizer, install a gas temperature monitor in the 
firebox of the thermal oxidizer or in the duct immediately downstream of 
the firebox before any substantial heat exchange occurs.
    (2) For a catalytic oxidizer, install gas temperature monitors 
upstream and/or downstream of the catalyst bed as required in Sec. 
63.3967(b).
    (3) For all thermal oxidizers and catalytic oxidizers, you must meet 
the requirements in paragraphs (a) and (c)(3)(i) through (v) of this

sensor output to a calibrated temperature measurement device or by 
comparing the sensor output to a simulated temperature.
    (iv) Conduct an accuracy audit every quarter and after every 
deviation. Accuracy audit methods include comparisons of sensor output 
to redundant temperature sensors, to calibrated temperature measurement 
devices, or to temperature simulation devices.
    (v) Conduct a visual inspection of each sensor every quarter if 
redundant temperature sensors are not used.
    (d) Regenerative carbon adsorbers. If you are using a regenerative 
carbon adsorber as an add-on control device, you must monitor the total 
regeneration desorbing gas (e.g., steam or nitrogen) mass flow for each 
regeneration cycle, the carbon bed temperature after each regeneration 
and cooling cycle, and comply with paragraphs (a)(3) through (5) and 
(d)(1) through (3) of this section.
    (1) The regeneration desorbing gas mass flow monitor must be an 
integrating device having a measurement sensitivity of plus or minus 10 
percent capable of recording the total regeneration desorbing gas mass 
flow for each regeneration cycle.
    (2) The carbon bed temperature monitor must be capable of recording 
the temperature within 15 minutes of completing any carbon bed cooling 
cycle.
    (3) For all regenerative carbon adsorbers, you must meet the 
requirements in paragraphs (c)(3)(i) through (v) of this section for 
each temperature monitoring device.

in paragraphs (a) and (g)(1)(i) through (vii) of this section.
    (i) Locate a flow sensor in a position that provides a 
representative flow measurement in the duct from each capture device in 
the emission capture system to the add-on control device.
    (ii) Use a flow sensor with an accuracy of at least 10 percent of 
the flow.
    (iii) Perform an initial sensor calibration in accordance with the

vehicles (including camping trailers and fifth wheels). Assembled on-
road vehicle coating includes the concurrent coating of parts of the 
assembled on-road vehicle that are painted off-vehicle to protect 
systems, equipment, or to allow full coverage. Assembled on-road vehicle 
coating does not include surface coating operations that meet the 
applicability criteria of the Automobiles and Light-Duty Trucks NESHAP. 
Assembled on-road vehicle coating also does not include the use of 
adhesives, sealants, and caulks used in assembling on-road vehicles.
    Automotive lamp coating means any coating operation in which coating 
is applied to the surface of some component of the body of an exterior 
automotive lamp, including the application of reflective argent coatings 
and clear topcoats. Exterior automotive lamps include head lamps, tail 
lamps, turn signals, brake lights, and side marker lights. Automotive

emissions generated by a coating operation in the use of coatings or 
cleaning materials, both at the point of application and at subsequent 
points where emissions from the coatings and cleaning materials occur, 
such as flashoff, drying, or curing. As used in this subpart, multiple 
capture devices that collect emissions generated by a coating operation 
are considered a single capture system.
    Cleaning material means a solvent used to remove contaminants and 
other materials, such as dirt, grease, oil, and dried or wet coating 
(e.g., depainting), from a substrate before or after coating application 
or from equipment associated with a coating operation, such as spray 
booths, spray guns, racks, tanks, and hangers. Thus, it includes any 
cleaning material used on substrates or equipment or both.
    Coating means a material applied to a substrate for decorative, 
protective, or functional purposes. Such materials include, but are not 
limited to, paints, sealants, liquid plastic coatings, caulks, inks, 
adhesives, and maskants. Decorative, protective, or functional materials 
that consist only of protective oils for metal, acids, bases, or any 
combination of these substances, or paper film or plastic film which may 
be pre-coated with an adhesive by the film manufacturer, are not 
considered coatings for the purposes of this subpart. A liquid plastic 
coating means a coating made from fine particle-size polyvinyl chloride 
(PVC) in solution (also referred to as a plastisol).
    Coating operation means equipment used to apply cleaning materials 
to a substrate to prepare it for coating application (surface

equipment (equipment cleaning). A single coating operation may include 
any combination of these types of equipment, but always includes at 
least the point at which a given quantity of coating or cleaning 
material is applied to a given part and all subsequent points in the 
affected source where organic HAP are emitted from the specific quantity 
of coating or cleaning material on the specific part. There may be 
multiple coating operations in an affected source. Coating application 
with handheld, non-refillable aerosol containers, touch-up markers, or 
marking pens is not a coating operation for the purposes of this 
subpart.
    Coatings solids means the nonvolatile portion of the coating that 
makes up the dry film.
    Continuous parameter monitoring system (CPMS) means the total 
equipment that may be required to meet the data acquisition and 
availability requirements of this subpart, used to sample, condition (if 
applicable), analyze, and provide a record of coating operation, or 
capture system, or add-on control device parameters.
    Controlled coating operation means a coating operation from which 
some or all of the organic HAP emissions are routed through an emission 
capture system and add-on control device.
    Deviation means any instance in which an affected source subject to 
this subpart, or an owner or operator of such a source:
    (1) Fails to meet any requirement or obligation established by this 
subpart including but not limited to, any emission limit or operating 
limit or work practice standard;
    (2) Fails to meet any term or condition that is adopted to implement 
an applicable requirement in this subpart and that is included in the 
operating permit for any affected source required to obtain such a 
permit; or

practice standard in this subpart during startup, shutdown, or 
malfunction, regardless of whether or not such failure is permitted by 
this subpart.
    Emission limitation means the aggregate of all requirements 
associated with a compliance option including emission limit, operating 
limit, work practice standard, etc.
    Enclosure means a structure that surrounds a source of emissions and 
captures and directs the emissions to an add-on control device.
    Exempt compound means a specific compound that is not considered a 
VOC due to negligible photochemical reactivity. The exempt compounds are 
listed in 40 CFR 51.100(s).
    Facility maintenance means the routine repair or renovation 
(including the surface coating) of the tools, equipment, machinery, and 
structures that comprise the infrastructure of the affected facility and 
that are necessary for the facility to function in its intended 
capacity.
    General use coating means any coating operation that is not an 
automotive lamp, TPO, or assembled on-road vehicle coating operation.
    Hobby shop means any surface coating operation, located at an 
affected source, that is used exclusively for personal, noncommercial 
purposes by the affected source's employees or assigned personnel.
    Manufacturer's formulation data means data on a material (such as a 
coating) that are supplied by the material manufacturer based on 
knowledge of the ingredients used to manufacture that material, rather 
than based on testing of the material with the test methods specified in 
Sec. 63.4541. Manufacturer's formulation data may include, but are not 
limited to, information on density, organic HAP content, volatile 
organic matter content, and coating solids content.
    Mass fraction of coating solids means the ratio of the mass of 
solids (also known as the mass of nonvolatiles) to the mass of a coating 
in which it is contained; kg of coating solids per kg of coating.
    Mass fraction of organic HAP means the ratio of the mass of organic 
HAP to the mass of a material in which it is contained, expressed as kg 
of organic HAP per kg of material.
    Month means a calendar month or a pre-specified period of 28 days to 
35 days to allow for flexibility in recordkeeping when data are based on

[[Page 759]]

    Non-HAP coating means, for the purposes of this subpart, a coating 
that contains no more than 0.1 percent by mass of any individual organic 
HAP that is an OSHA-defined carcinogen as specified in 29 CFR 
1910.1200(d)(4) and no more than 1.0 percent by mass for any other 
individual HAP.
    Organic HAP content means the mass of organic HAP emitted per mass 
of coating solids used for a coating calculated using Equation 1 of 
Sec. 63.4541. The organic HAP content is determined for the coating in 
the condition it is in when received from its manufacturer or supplier 
and does not account for any alteration after receipt. For reactive 
adhesives in which some of the HAP react to form solids and are not 
emitted to the atmosphere, organic HAP content is the mass of organic 
HAP that is emitted, rather than the organic HAP content of the coating 
as it is received.
    Permanent total enclosure (PTE) means a permanently installed 
enclosure that meets the criteria of Method 204 of appendix M, 40 CFR 
part 51, for a PTE and that directs all the exhaust gases from the

which at least one has been formed from one or more resins. Such pieces 
may be solid, porous, flexible or rigid.
    Protective oil means an organic material that is applied to metal 
for the purpose of providing lubrication or protection from corrosion 
without forming a solid film. This definition of protective oil 
includes, but is not limited to, lubricating oils, evaporative oils 
(including those that evaporate completely), and extrusion oils.
    Reactive adhesive means adhesive systems composed, in part, of 
volatile monomers that react during the adhesive curing reaction, and, 
as a result, do not evolve from the film during use. These volatile 
components instead become integral parts of the adhesive through 
chemical reaction. At least 70 percent of the liquid components of the 
system, excluding water, react during the process.
    Research or laboratory facility means a facility whose primary 
purpose is for research and development of new processes and products, 
that is conducted under the close supervision of technically trained 
personnel, and is not engaged in the manufacture of final or 
intermediate products for commercial purposes, except in a de minimis 
manner.
    Responsible official means responsible official as defined in 40 CFR 
70.2.
    Startup, initial means the first time equipment is brought online in 
a facility.
    Surface preparation means use of a cleaning material on a portion of 
or all of a substrate. This includes use of a cleaning material to 
remove dried coating, which is sometimes called depainting.
    Temporary total enclosure means an enclosure constructed for the 
purpose of measuring the capture efficiency of pollutants emitted from a 
given source as defined in Method 204 of appendix M, 40 CFR part 51.

not limited to, thermoplastic elastomer (TPE), TPE polyurethane (TPU), 
TPE polyester (TPEE), TPE polyamide (TPAE), and thermoplastic elastomer 
polyvinyl chloride (TPVC).
    Thermoplastic olefin (TPO) coating means any coating operation in 
which the coatings are components of a system of coatings applied to a 
TPO substrate, including adhesion promoters, primers, color coatings, 
clear coatings and topcoats. Thermoplastic olefin coating does not 
include the coating of TPO substrates on assembled on-road vehicles.
    Thinner means an organic solvent that is added to a coating after 
the coating is received from the supplier.
    Total volatile hydrocarbon (TVH) means the total amount of 
nonaqueous

[[Page 760]]

volatile organic matter determined according to Methods 204 and 204A 
through 204F of appendix M to 40 CFR part 51 and substituting the term 
TVH each place in the methods where the term VOC is used. The TVH 
includes both VOC and non-VOC.
    Uncontrolled coating operation means a coating operation from which 
none of the organic HAP emissions are routed through an emission capture 
system and add-on control device.

  Sec. Appendix A to Subpart PPPP of Part 63--Determination of Weight 
 Volatile Matter Content and Weight Solids Content of Reactive Adhesives

                     1.0 Applicability and Principle

    1.1 Applicability: This method applies to the determination of 
weight volatile matter content and weight solids content for most one-
part or multiple-part reactive adhesives. Reactive adhesives are 
composed, in large part, of monomers that react during the adhesive 
curing reaction, and, as a result, do not volatilize. The monomers 
become integral parts of the cured adhesive through chemical reaction. 
At least 70 weight percent of the system, excluding water and non-
volatile solids such as fillers, react during the process. This method 
is not appropriate for cyanoacrylates. For cyanoacrylates, South Coast 
Air Quality Management District Test Method 316B should be used. This 
method is not appropriate for one-part moisture cure urethane adhesives 
or for silicone adhesives. For one-part moisture cure urethane adhesives 
and for silicone adhesives, EPA Method 24 should be used.
    1.2 Principle: One-part and multiple-part reactive adhesives undergo 
a reactive conversion from liquid to solid during the application and 
assembly process. Reactive adhesives are applied to a single surface, 
but then are usually quickly covered with another mating surface to 
achieve a bonded assembly. The monomers employed in such systems 
typically react and are converted to non-volatile solids. If left 
uncovered, as in a Method 24 (ASTM D2369) test, the reaction is 
inhibited by the presence of oxygen and volatile loss of the reactive 
components competes more heavily with the cure reaction. If this were to 
happen under normal use conditions, the adhesives would not provide 
adequate performance. This method minimizes this undesirable 
deterioration of the adhesive performance.

                       2.0 Materials and Apparatus

    2.1 Aluminum foil, aluminum sheet, non-leaching plastic film or non-
leaching plastic sheet, approximately 3 inches by 3 inches. Precondition 
the foil, film, or sheet for 30 minutes in an oven at 110 5 degrees Celsius and store in a desiccator prior to 
use. Use tongs or rubber gloves or both to handle the foil, film, or 
sheet.
    2.2 Flat, rigid support panels slightly larger than the foil, film, 
or sheet. Polypropylene with a minimum thickness of \1/8\ inch is 
recommended for the support panels. Precondition the support panels for 
30 minutes in an oven at 110 5 degrees Celsius and 
store in a desiccator prior to use. Use tongs or rubber gloves or both 
to handle the support panels.
    2.3 Aluminum spacers, \1/8\ inch thick. Precondition the spacers for 
30 minutes in an oven at 110 5 degrees Celsius and 
store in a desiccator prior to use. Use tongs or rubber gloves or both 
to handle the spacers.
    2.4 Forced draft oven, type IIA or IIB as specified in ASTM E145-94 
(Reapproved 2001), ``Standard Specification for Gravity-Convection and 
Forced-Ventilation Ovens'' (incorporated by reference, see Sec. 63.14).
    2.5 Electronic balance capable of weighing to 0.0001 grams (0.1 mg).
    2.6 Flat bottom weight (approximately 3 lbs) or clamps.

                      Material and Apparatus Notes

    1--The foil, film, or sheet should be thick or rigid enough so that 
it can be easily handled in the test procedure.

[[Page 766]]

                              3.0 Procedure

    3.1 Two procedures are provided. In Procedure A the initial specimen 
weight is determined by weighing the foil, film, or sheet before and 
after the specimen is dispensed onto the foil, film, or sheet. In 
Procedure B the initial specimen weight is determined by weighing the 
adhesive cartridge (kit) before and after the specimen is dispensed.
    3.2 At least four test specimens should be run for each test 
material. Run the test at room temperature, 74 degrees Fahrenheit (23 
degrees Celsius).

                               Procedure A

    1. Zero electronic balance.
    2. Place 2 pieces of aluminum foil (or aluminum sheet, plastic film, 
or plastic sheet) on scale.
    3. Record weight of aluminum foils. (A).
    4. Tare balance.
    5. Remove top piece of aluminum foil.
    6. Dispense a 10 to 15 gram specimen of premixed adhesive onto 
bottom piece of aluminum foil. Place second piece of aluminum foil on 
top of the adhesive specimen to make a sandwich.
    7. Record weight of sandwich (specimen and aluminum foils). (B).
    8. Remove sandwich from scale, place sandwich between two support 
panels with aluminum spacers at the edges of the support panels to make 
a supported sandwich. The spacers provide a standard gap. Take care to 
mate the edges.
    9. Place the supported sandwich on a flat surface.
    10. Place the weight on top of the supported sandwich to spread the 
adhesive specimen to a uniform thickness within the sandwich. Check that 
no adhesive squeezes out from between the pieces of aluminum foil or 
through tears in the aluminum foil.
    11. Allow to cure 24 hours.
    12. Remove the sandwich from between the support panels. Record the 
weight of the sandwich. This is referred to as the 24 hr weight. (C).
    13. Bake sandwich at 110 degrees Celsius for 1 hour.
    14. Remove sandwich from the oven, place immediately in a 
desiccator, and cool to room temperature. Record post bake sandwich 
weight. (D).

                               Procedure B

    1. Zero electronic balance.
    2. Place two pieces of aluminum foil (or aluminum sheet, plastic 
film, or plastic sheet) on scale.
    3. Record weight of aluminum foils. (A).
    4. Tare balance.
    5. Place one support panel on flat surface. Place first piece of 
aluminum foil on top of this support panel.
    6. Record the weight of a pre-mixed sample of adhesive in its 
container. If dispensing the adhesive from a cartridge (kit), record the 
weight of the cartridge (kit) plus any dispensing tips. (F).
    7. Dispense a 10 to 15 gram specimen of mixed adhesive onto the 
first piece of aluminum foil. Place second piece of aluminum foil on top 
of the adhesive specimen to make a sandwich.
    8. Record weight of the adhesive container. If dispensing the 
adhesive from a cartridge (kit), record the weight of the cartridge 
(kit) plus any dispensing tips. (G).
    9. Place the aluminum spacers at the edges of the bottom support 
panel polypropylene sheet. The spacers provide a standard gap.
    10. Place the second support panel on top of the assembly to make a 
supported sandwich. Take care to mate the edges.
    11. Place the supported sandwich on a flat surface.
    12. Place the weight on top of the supported sandwich to spread the 
adhesive specimen to a uniform thickness within the sandwich. Check that 
no adhesive squeezes out from between the pieces of aluminum foil or 
through tears in the aluminum foil.
    13. Allow to cure 24 hours.
    14. Remove the sandwich from between the support panels. Record the 
weight of the sandwich. This is referred to as the 24 hr weight. (C).
    15. Bake sandwich at 110 degrees Celsius for 1 hour.
    16. Remove sandwich from the oven, place immediately in a 
desiccator, and cool to room temperature.
    17. Record post-bake sandwich weight. (D).

                            Procedural Notes

    1--The support panels may be omitted if the aluminum foil (or 
aluminum sheet, plastic film, or plastic sheet) will not tear and the 
adhesive specimen will spread to a uniform thickness within the sandwich 
when the flat weight is placed directly on top of the sandwich.
    2--Clamps may be used instead of a flat bottom weight to spread the 
adhesive specimen to a uniform thickness within the sandwich.
    3--When dispensing from a static mixer, purging is necessary to 
ensure uniform, homogeneous specimens. The weighing in Procedure B, Step 
6 must be performed after any purging.
    4--Follow the adhesive manufacturer's directions for mixing and for 
dispensing from a cartridge (kit).

                            4.0 Calculations

    4.1 The total weight loss from curing and baking of each specimen is 
used to determine the weight percent volatile matter content of that 
specimen

[[Page 767]]

                               Procedure A

Weight of original specimen (S) = (B)-(A)
Weight of post-bake specimen (P) = (D)-(A)
Total Weight Loss (L) = (S)-(P)

                               Procedure B

Weight of original specimen (S) = (F)-(G)
Weight of post-bake specimen (P) = (D)-(A)
Total Weight Loss (L) = (S)-(P)

                       Procedure A and Procedure B

                 Weight Percent Volatile Matter Content

(V) = [(Total weight loss)/(Initial specimen weight)] x 100 = [(L)/(S)] 
          x 100

    4.2 The weight volatile matter content of a material is the average 
of the weight volatile matter content of each specimen of that material. 
For example, if four specimens of a material were tested, then the 
weight percent volatile matter content for that material is:

V = [V1 + V2 + V3 + V4]/4

Where:

Vi = the weight percent volatile matter content of specimen i of the 
          material.

    4.3 The weight percent solids content of the material is calculated 
from the weight percent volatile content of the material.

Weight Percent Solids Content (N) = 100-(V)

                            Calculation Notes

    1--The weight loss during curing and the weight loss during baking 
may be calculated separately. These values may be useful for identifying 
sources of variation in the results obtained for different specimens of 
the same material.
    2--For both Procedure A and Procedure B, the weight loss during 
curing is (S)-[(C)-(A)] and the weight loss during baking is (C)-(D).

                          Emission Limitations



Sec. 63.4690  What emission limits must I meet?

    (a) For a new or reconstructed affected source, you must limit 
organic HAP emissions to the atmosphere to no more than the applicable 
emission limit(s) in Table 1 to this subpart, determined according to 
the requirements in Sec. Sec. 63.4741, 63.4751, or 63.4761.
    (b) For an existing affected source, you must limit organic HAP 
emissions to the atmosphere to no more than the applicable emission 
limit(s) in Table 2 to this subpart, determined according to the 
requirements in Sec. 63.4741, Sec. 63.4751, or Sec. 63.4761.
    (c) If the affected source applies coatings to products that are in 
different subcategories as described in Sec. 63.4681(a), then you must 
demonstrate initial and continuous compliance by selecting one of the 
approaches described in paragraphs (c)(1) and (2) of this section.
    (1) Conduct separate compliance demonstrations for each applicable 
subcategory emission limit and reflect these separate determinations in 
notifications, reports, and records required by Sec. Sec. 63.4710, 
63.4720, and 63.4730, respectively.
    (2) Demonstrate compliance with the most stringent of the applicable 
subcategory emission limits.



Sec. 63.4691  What are my options for meeting the emission limits?

    You must include all coatings, thinners, and cleaning materials used 
in the affected source when determining whether the organic HAP emission 
rate is equal to or less than the applicable

[[Page 770]]

emission limit in Sec. 63.4690. To make this determination, you must 
use at least one of the three compliance options listed in paragraphs 
(a) through (c) of this section. You may apply any of the compliance 
options to an individual coating operation or to multiple coating 
operations as a group or to the entire affected source. You may use 
different compliance options for different coating operations or at 
different times on the same coating operation. However, you may not use 
different compliance options at the same time on the same coating 
operation. If you switch between compliance options for any coating 
operation or group of coating operations, you must document this switch 
as required by Sec. 63.4730(c), and you must report it in the next 
semiannual compliance report required in Sec. 63.4720.
    (a) Compliant material option. Demonstrate that the organic HAP 
content of each coating used in the coating operation(s) is less than or 
equal to the applicable emission limit(s) in Sec. 63.4690, and that 
each thinner and each cleaning material used contains no organic HAP. 
You must meet all the requirements of Sec. Sec. 63.4740, 63.4741, and 
63.4742 to demonstrate compliance with the emission limit using this 
option.
    (b) Emission rate without add-on controls option. Demonstrate that, 
based on the coatings, thinners, and cleaning materials used in the 
coating operation(s), the organic HAP emission rate for the coating 
operation(s) is less than or equal to the applicable emission limit(s) 
in Sec. 63.4690, calculated as a rolling 12-month emission rate and 
determined on a monthly basis. You must meet all the requirements of 
Sec. Sec. 63.4750, 63.4751, and 63.4752 to demonstrate compliance with 
the emission limit using this option.
    (c) Emission rate with add-on controls option. Demonstrate that, 
based on the coatings, thinners, and cleaning materials used in the 
coating operation(s) and the emission reductions achieved by emission 
capture systems and add-on controls, the organic HAP emission rate for 
the coating operation(s) is less than or equal to the applicable 
emission limit(s) in Sec. 63.4690, calculated as a rolling 12-month 
emission rate and determined on a monthly basis. If you use this 
compliance option, you must also demonstrate that all emission capture 
systems and add-on control devices for the coating operation(s) meet the 
operating limits required in Sec. 63.4692, except for solvent recovery 
systems for which you conduct liquid-liquid material balances according 
to Sec. 63.4761(j), and that you meet the work practice standards 
required in Sec. 63.4693. You must meet all the requirements of 
Sec. Sec. 63.4760 through 63.4768 to demonstrate compliance with the 
emission limits, operating limits, and work practice standards using 
this option.



Sec. 63.4692  What operating limits must I meet?

    (a) For any coating operation(s) on which you use the compliant 
material option or the emission rate without add-on controls option, you 
are not required to meet any operating limits.
    (b) For any controlled coating operation(s) on which you use the 
emission rate with add-on controls option, except those for which you 
use a solvent recovery system and conduct a liquid-liquid material 
balance according to Sec. 63.4761(j), you must meet the operating 
limits specified in Table 3 to this subpart. These operating limits 
apply to the emission capture and control systems on the coating 
operation(s) for which you use this option, and you must establish the 
operating limits during the performance test according to the 
requirements in Sec. 63.4767. You must meet the operating limits at all 
times after you establish them.
    (c) If you use an add-on control device other than those listed in 
Table 3 to this subpart, or wish to monitor an alternative parameter and 
comply with a different operating limit, you must apply to the 
Administrator for approval of alternative monitoring under Sec. 
63.8(f).



Sec. 63.4693  What work practice standards must I meet?

    (a) For any coating operation(s) on which you use the compliant 
material option or the emission rate without add-on controls option, you 
are not required to meet any work practice standards.

[[Page 771]]

    (b) If you use the emission rate with add-on controls option, you 
must develop and implement a work practice plan to minimize organic HAP 
emissions from the storage, mixing, and conveying of coatings, thinners, 
and cleaning materials used in, and waste materials generated by, the 
coating operation(s); or you must meet an alternative standard as 
provided in paragraph (d) of this section. The plan must specify 
practices and procedures to ensure that, at a minimum, the elements 
specified in paragraphs (b)(1) through (5) of this section are 
implemented. You must make the plan available upon request for 
inspection by the Administrator.
    (1) All organic-HAP coatings, thinners, cleaning materials, and 
waste materials must be stored in closed containers.
    (2) Spills of organic-HAP coatings, thinners, cleaning materials, 
and waste materials must be minimized.
    (3) Organic-HAP coatings, thinners, cleaning materials, and waste 
materials must be conveyed from one location to another in closed 
containers or pipes.
    (4) Mixing vessels that contain organic-HAP coatings and other 
materials must be closed except when adding to, removing, or mixing the 
contents.
    (5) Emissions of organic-HAP must be minimized during cleaning of 
storage, mixing, and conveying equipment.
    (c) If your affected source has an existing documented plan that 
incorporates steps taken to minimize emissions from the sources 
specified in paragraphs (b)(1) through (5) of this section, then your 
existing plan can be used to meet the requirement for a work practice 
plan as specified in paragraph (b) of this section.
    (d) As provided in Sec. 63.6(g), we, the U.S. Environmental 
Protection Agency (U.S. EPA), may choose to grant you permission to use 
an alternative to the work practice standards in this section.

        Compliance Requirements for the Compliant Material Option



Sec. 63.4740  By what date must I conduct the initial compliance
demonstration?

    You must complete the initial compliance demonstration for the 
initial compliance period according to the requirements in Sec. 
63.4741. The initial compliance period begins on the applicable 
compliance date specified in Sec. 63.4683 and ends on the last day of 
the 12th month following the compliance date. If the compliance date 
occurs on any day other than the first day of a month, then the initial 
compliance period extends through the end of that month plus the next 12 
months. The initial compliance demonstration includes the calculations 
according to Sec. 63.4741 and supporting documentation showing that 
during the initial compliance period, you used no coating with an 
organic HAP content that exceeded the applicable emission limit in Sec. 
63.4690, and that you used no thinners or cleaning materials that 
contained organic HAP.



Sec. 63.4741  How do I demonstrate initial compliance with the
emission limitations?

    You may use the compliant material option for any individual coating 
operation, for any group of coating operations in the affected source, 
or for all the coating operations in the affected source. You must use 
either the emission rate without add-on controls option or the emission 
rate with add-on controls option for any coating operation in the 
affected source for which you do not use this option. To demonstrate 
initial compliance using the compliant material option, the coating 
operation or group of coating operations must use no coating with an 
organic HAP content that exceeds the applicable emission limit in Sec. 
63.4690 and must use no thinner or cleaning material that contains 
organic HAP as determined according to this section. Any coating 
operation for which you use the compliant material option is not 
required to meet the operating limits or work practice standards 
required in Sec. Sec. 63.4692 and 63.4693, respectively. To demonstrate 
initial compliance with the emission limitations using the compliant 
material option, you must meet all the requirements of this section for 
the coating operation or group of coating operations using this option. 
Use the procedures in this section on each coating, thinner, and 
cleaning material in the condition it is in when it is received from its 
manufacturer or supplier and prior to any alteration. You do not need to 
redetermine the mass of organic HAP in coatings, thinners, or cleaning 
materials that have been reclaimed onsite and reused in the coating 
operation(s) for which you use the compliant material option, provided 
these materials in their condition as received were demonstrated to 
comply with the compliant material option. If the mass fraction of 
organic HAP of a coating equals zero, determined according to paragraph 
(a) of this section, and you use the compliant material option, you are 
not required to comply with paragraphs (b) and (c) of this section for 
that coating.
    (a) Determine the mass fraction of organic HAP for each material 
used. You must determine the mass fraction of organic HAP for each 
coating, thinner, and cleaning material used during the compliance 
period by using one of the options in paragraphs (a)(1) through (5) of 
this section.
    (1) Method 311 (appendix A to 40 CFR part 63). You may use Method 
311 for determining the mass fraction of organic HAP. Use the procedures 
specified in paragraphs (a)(1)(i) and (ii) of this section when 
performing a Method 311 test. If these values cannot be determined using 
Method 311, the owner or operator shall submit an alternative technique 
for determining their values for approval by the Administrator.

[[Page 780]]

    (i) Count each organic HAP that is measured to be present at 0.1 
percent by mass or more for OSHA-defined carcinogens as specified in 29 
CFR 1910.1200(d)(4), and at 1.0 percent by mass or more for other 
organic HAP compounds. For example, if toluene (not an OSHA carcinogen) 
is measured to be 0.5 percent of the material by mass, you do not have 
to count it. Express the mass fraction of each organic HAP you count as 
a value truncated to four places after the decimal point (e.g., 
0.379178412 truncates to 0.3791).
    (ii) Calculate the total mass fraction of organic HAP in the test 
material by adding up the individual organic HAP mass fractions and 
truncating the result to three places after the decimal point (e.g., 
0.763).
    (2) Method 24 (appendix A to 40 CFR part 60). For coatings, you may 
use Method 24 to determine the mass fraction of nonaqueous volatile 
matter and use that value as a substitute for mass fraction of organic 
HAP. (Note: Method 24 is not appropriate for those coatings with a water 
content that would result in an effective detection limit greater than 
the applicable emission limit.)
    (3) Alternative method. You may use an alternative test method for 
determining the mass fraction of organic HAP once the Administrator has 
approved it. You must follow the procedure in Sec. 63.7(f) to submit an 
alternative test method for approval.
    (4) Information from the supplier or manufacturer of the material. 
You may rely on information other than that generated by the test 
methods specified in paragraphs (a)(1) through (3) of this section, such 
as manufacturer's formulation data, if it represents each organic HAP 
that is present at 0.1 percent by mass or more for OSHA-defined 
carcinogens as specified in 29 CFR 1910.1200(d)(4), and at 1.0 percent 
by mass or more for other organic HAP compounds. For example, if toluene 
(not an OSHA carcinogen) is 0.5 percent of the material by mass, you do 
not have to count it. If there is a disagreement between such 
information and results of a test conducted according to paragraphs 
(a)(1) through (3) of this section, then the test method results will 
take precedence unless, after consultation, a regulated source could 
demonstrate to the satisfaction of the enforcement agency that the 
formulation data were correct.
    (5) Solvent blends. Solvent blends may be listed as single 
components for some materials in data provided by manufacturers or 
suppliers. Solvent blends may contain organic HAP which must be counted 
toward the total organic HAP mass fraction of the materials. When test 
data and manufacturer's data for solvent blends are not available, you 
may use the default values for the mass fraction of organic HAP in these 
solvent blends listed in Table 5 or Table 6 to this subpart. If you use 
the tables, you must use the values in Table 5 for all solvent blends 
that match Table 5 entries, and you may only use Table 6 if the solvent 
blends in the materials you use do not match any of the solvent blends 
in Table 5 and you only know whether the blend is aliphatic or aromatic. 
However, if the results of a Method 311 (40 CFR part 63, appendix A) 
test indicate higher values than those listed on Table 5 or Table 6 to 
this subpart, the Method 311 results will take precedence.
    (b) Determine the volume fraction of coating solids for each 
coating. You must determine the volume fraction of coating solids 
(liters of coating solids per liter of coating) for each coating used 
during the compliance period by one of the methods specified in 
paragraph (b)(1), (2), or (3) of this section.
    (1) ASTM Method D2697-86 (Reapproved 1998) or D6093-97. You may use 
ASTM Method D2697-86 (Reapproved 1998), ``Standard Test Method for 
Volume Nonvolatile Matter in Clear or Pigmented Coatings' (incorporated 
by reference, see Sec. 63.14), or D6093-97, ``Standard Test Method for 
Percent Volume Nonvolatile Matter in Clear or Pigmented Coatings Using a 
Helium Gas Pycnometer'' (incorporated by reference, see Sec. 63.14), to 
determine the volume fraction of coating solids for each coating. Divide 
the nonvolatile volume percent obtained with the methods by 100 to 
calculate volume fraction of coating solids. If these values cannot be 
determined using these methods, the owner operator may submit an 
alternative technique for determining their values for approval by the 
Administrator.

[[Page 781]]

    (2) Information from the supplier or manufacturer of the material. 
You may obtain the volume fraction of coating solids for each coating 
from the supplier or manufacturer.
    (3) Calculation of volume fraction of coating solids. If the volume 
fraction of coating solids cannot be determined using the options in 
paragraphs (b)(1) and (2) of this section, you must determine it using 
Equation 1 of this section:
[GRAPHIC] [TIFF OMITTED] TR98AD03.000

Where:

Vs = Volume fraction of coating solids, liters coating solids 
          per liter coating.
mvolatiles = Total volatile matter content of the coating, 
          including HAP, volatile organic compounds (VOC), water, and 
          exempt compounds, determined according to Method 24 in 
          appendix A of 40 CFR part 60, grams volatile matter per liter 
          coating.
Davg = Average density of volatile matter in the coating, 
          grams volatile matter per liter volatile matter, determined 
          from test results using ASTM Method D1475-90 information from 
          the supplier or manufacturer of the material, or reference 
          sources providing density or specific gravity data for pure 
          materials. If there is disagreement between ASTM Method D1475-
          90 test results and other information sources, the test 
          results will take precedence.

    (c) Determine the density of each coating. Determine the density of 
each coating used during the compliance period from test results using 
ASTM Method D1475-90 or information from the supplier or manufacturer of 
the material. If there is disagreement between ASTM Method D1475-90 test 
results and the supplier's or manufacturer's information, the test 
results will take precedence.
    (d) Calculate the organic HAP content of each coating. Calculate the 
organic HAP content, grams organic HAP per liter coating solids, of each 
coating used during the compliance period, using Equation 2 of this 
section:
[GRAPHIC] [TIFF OMITTED] TR98AD03.001

Where:

Hc = Organic HAP content of the coating, grams organic HAP 
          per liter coating solids.
Dc = Density of coating, grams coating per liter coating, 
          determined according to paragraph (c) of this section.
Wc = Mass fraction of organic HAP in the coating, grams 
          organic HAP per gram coating, determined according to 
          paragraph (a) of this section.
Vs = Volume fraction of coating solids, liter coating solids 
          per liter coating, determined according to paragraph (b) of 
          this section.

    (e) Compliance demonstration. The organic HAP content for each 
coating used during the initial compliance period, determined using 
Equation 2 of this section, must be less than or equal to the applicable 
emission limit in Sec. 63.4690; and each thinner and cleaning material 
used during the initial compliance period must contain no organic HAP, 
determined according to paragraph (a) of this section. You must keep all 
records required by Sec. Sec. 63.4730 and 63.4731. As part of the 
Notification of Compliance Status required in Sec. 63.4710, you must 
identify the coating operation(s) for which you used the compliant 
material option and submit a statement that the coating operation(s) was 
(were) in compliance with the emission limitations during the initial 
compliance period because you used no coatings for which the organic HAP 
content exceeded the applicable emission limit in Sec. 63.4690, and you 
used no thinners or cleaning materials that contained organic HAP, 
determined according to paragraph (a) of this section.



Sec. 63.4742  How do I demonstrate continuous compliance with the
emission limitations?

    (a) For each compliance period to demonstrate continuous compliance, 
you must use no coating for which the organic HAP content determined 
using Equation 2 of Sec. 63.4741 exceeds the applicable emission limit 
in Sec. 63.4690; and use no thinner or cleaning material that contains 
organic HAP, determined according to Sec. 63.4741(a). A compliance 
period consists of 12 months. Each month after the end of the initial 
compliance period described in Sec. 63.4740 is

[[Page 782]]

the end of a compliance period consisting of that month and the 
preceding 11 months.
    (b) If you choose to comply with the emission limitations by using 
the compliant material option, the use of any coating, thinner, or 
cleaning material that does not meet the criteria specified in paragraph 
(a) of this section is a deviation from the emission limitations that 
must be reported as specified in Sec. Sec. 63.4710(c)(6) and 
63.4720(a)(5).
    (c) As part of each semiannual compliance report required by Sec. 
63.4720, you must identify the coating operation(s) for which you used 
the compliant material option. If there were no deviations from the 
emission limitations in Sec. 63.4690, submit a statement that the 
coating operation(s) was (were) in compliance with the emission 
limitations during the reporting period because you used no coating for 
which the organic HAP content exceeded the applicable emission limit in 
Sec. 63.4690, and you used no thinner or cleaning material that 
contained organic HAP, determined according to Sec. 63.4741(a).
    (d) You must maintain records as specified in Sec. Sec. 63.4730 and 
63.4731.

 Compliance Requirements for the Emission Rate Without Add-On Controls 
                                 Option



Sec. 63.4750  By what date must I conduct the initial compliance
demonstration?

    You must complete the initial compliance demonstration for the 
initial compliance period according to the requirements of Sec. 
63.4751. The initial compliance period begins on the applicable 
compliance date specified in Sec. 63.4683 and ends on the last day of 
the 12th month following the compliance date. If the compliance date 
occurs on any day other than the first day of a month, then the initial 
compliance period extends through the end of that month plus the next 12 
months. You must determine the mass of organic HAP emissions and volume 
of coating solids used each month and then calculate a 12-month organic 
HAP emission rate at the end of the initial 12-month compliance period. 
The initial compliance demonstration includes the calculations according 
to Sec. 63.4751 and supporting documentation showing that during the 
initial compliance period the organic HAP emission rate was equal to or 
less than the applicable emission limit in Sec. 63.4690.



Sec. 63.4751  How do I demonstrate initial compliance with the emission
limitations?

    You may use the emission rate without add-on controls option for any 
individual coating operation, for any group of coating operations in the 
affected source, or for all the coating operations in the affected 
source. You must use either the compliant material option or the 
emission rate with add-on controls option for any coating operation in 
the affected source for which you do not use this option. To demonstrate 
initial compliance using the emission rate without add-on controls 
option, the coating operation or group of coating operations must meet 
the applicable emission limit in Sec. 63.4690. Any coating operation 
for which you use the emission rate without add-on controls option is 
not required to meet the operating limits or work practice standards 
required in Sec. Sec. 63.4692 and 63.4693, respectively. You must meet 
all the requirements of this section to demonstrate initial compliance 
with the applicable emission limit in Sec. 63.4690 for the coating 
operation(s). When calculating the organic HAP emission rate according 
to this section, do not include any coatings, thinners, or cleaning 
materials used on coating operations for which you use the compliant 
material option or the emission rate with add-on controls option. You do 
not need to redetermine the mass of organic HAP in coatings, thinners, 
or cleaning materials that have been reclaimed onsite and reused in the 
coating operation(s) for which you use the emission rate without add-on

required by Sec. 63.4710, you must identify the coating operation(s) 
for which you used the emission rate without add-on controls option and 
submit a statement that the coating operation(s) was (were) in 
compliance with the emission limitations during the initial compliance 
period because the organic HAP emission rate was less than or equal to 
the applicable emission limit in Sec. 63.4690, determined according to 
this section.



Sec. 63.4752  How do I demonstrate continuous compliance with the
emission limitations?

    (a) To demonstrate continuous compliance, the organic HAP emission 
rate for each compliance period, calculated using Equation 3 of Sec. 
63.4751, must be less than or equal to the applicable emission limit in 
Sec. 63.4690. A compliance period consists of 12 months. Each month 
after the end of the initial compliance period described in Sec. 
63.4750 is the end of a compliance period consisting of that month and 
the preceding 11 months. You must perform the calculations in Sec. 
63.4751(a) through (g) on a monthly basis using data from the previous 
12 months of operation.
    (b) If the organic HAP emission rate for any 12-month compliance 
period exceeded the applicable emission limit in Sec. 63.4690, this is 
a deviation from the emission limitations for that compliance period and 
must be reported as specified in Sec. Sec. 63.4710(c)(6) and 
63.4720(a)(6).
    (c) As part of each semiannual compliance report required by Sec. 
63.4720, you must identify the coating operation(s) for which you used 
the emission rate without add-on controls option. If there were no 
deviations from the emission limitations, you must submit a statement 
that the coating operation(s) was (were) in compliance with the emission 
limitations during the reporting period because the organic HAP emission 
rate for each compliance period was less than or equal to the applicable 
emission limit in Sec. 63.4690, determined according to Sec. 
63.4751(a) through (g).
    (d) You must maintain records as specified in Sec. Sec. 63.4730 and 
63.4731.

                                 Option



Sec. 63.4760  By what date must I conduct performance tests and
other initial compliance demonstrations?

    (a) New and reconstructed affected sources. For a new or 
reconstructed affected source, you must meet the requirements of 
paragraphs (a)(1) through (4) of this section.
    (1) All emission capture systems, add-on control devices, and CPMS 
must be installed and operating no later than the applicable compliance 
date specified in Sec. 63.4683. Except for solvent recovery systems for 
which you conduct liquid-liquid material balances according to Sec. 
63.4761(j), you must conduct a performance test of each capture system 
and add-on control device according to Sec. Sec. 63.4764, 63.4765, and

the 12th month following the compliance date. If the compliance date 
occurs on any day other than the first day of a

[[Page 786]]

month, then the initial compliance period extends through the end of 
that month plus the next 12 months. You must determine the mass of 
organic HAP emissions and volume of coating solids used each month and 
then calculate a 12-month organic HAP emission rate at the end of the 
initial 12-month compliance period. The initial compliance demonstration 
includes the results of emission capture system and add-on control 
device performance tests conducted according to Sec. Sec. 63.4764, 
63.4765, and 63.4766; results of liquid-liquid material balances

emission capture system and add-on control device required by Sec. 
63.4692 until after you have completed the performance tests specified 
in paragraph (a)(1) of this section. Instead, you must maintain a log 
detailing the operation and maintenance of the emission capture system, 
add-on control device, and continuous parameter monitors during the 
period between the compliance date and the performance test. You must 
begin complying with the operating limits for your affected source on 
the date you complete the performance tests specified in paragraph 
(a)(1) of this section. The requirements in this paragraph (a)(4) do not 
apply to solvent recovery systems for which you conduct liquid-liquid 
material balances according to the requirements in Sec. 63.4761(j).
    (b) Existing affected sources. For an existing affected source, you 
must meet the requirements of paragraphs (b)(1) through (3) of this 
section.
    (1) All emission capture systems, add-on control devices, and CPMS

initial compliance period according to the requirements of Sec. 
63.4761. The initial compliance period begins on the applicable 
compliance date specified in Sec. 63.4683 and ends on the last day of 
the 12th month following the compliance date. If the compliance date 
occurs on any day other than the first day of a month, then the initial 
compliance period extends through the end of that month plus the next 12 
months. You must determine the mass of organic HAP emissions and volume 
of coating solids used each month and then calculate a 12-month organic 
HAP emission rate at the end of the initial 12-month compliance period.

[[Page 787]]



Sec. 63.4761  How do I demonstrate initial compliance?

    (a) You may use the emission rate with add-on controls option for 
any coating operation, for any group of coating operations in the 
affected source, or for all of the coating operations in the affected 
source. You may include both controlled and uncontrolled coating 
operations in a group for which you use this option. You must use either 
the compliant material option or the emission rate without add-on 
controls option for any coating operation in the affected source for 
which you do not use the emission rate with add-on controls option. To 
demonstrate initial compliance, the coating operation(s) for which you 
use the emission rate with add-on controls option must meet the 
applicable emission limitations in Sec. Sec. 63.4690, 63.4692, and 
63.4693. You must meet all the requirements of this section to 
demonstrate initial compliance with the emission limitations. When 
calculating the organic HAP emission rate according to this section, do 
not include any coatings, thinners, or cleaning materials used on 
coating operations for which you use the compliant material option or 
the emission rate without add-on controls option. You do not need to 
redetermine the mass of organic HAP in coatings, thinners, or cleaning 
materials that have been reclaimed and reused in the coating 
operation(s) for which you use the emission rate with add-on controls 
option.
    (b) Compliance with operating limits. Except as provided in Sec. 
63.4760(a)(4), and except for solvent recovery systems for which you 
conduct liquid-liquid material balances according to the requirements of 
Sec. 63.4761(j), you must establish and demonstrate continuous 
compliance during the initial compliance period with the operating 
limits required by Sec. 63.4692, using the procedures specified in 
Sec. Sec. 63.4767 and 63.4768.
    (c) Compliance with work practice requirements. You must develop, 
implement, and document your implementation of the work practice plan 
required by Sec. 63.4693 during the initial compliance period, as 
specified in Sec. 63.4730.
    (d) Compliance with emission limits. You must follow the procedures 
in paragraphs (e) through (n) of this section to demonstrate compliance 
with the applicable emission limit in Sec. 63.4690.
    (e) Determine the mass fraction of organic HAP, density, volume 
used, and volume fraction of coating solids. Follow the procedures 
specified in Sec. 63.4751(a) through (d) to determine the mass fraction 
of organic HAP, density, and volume of each coating, thinner, and 
cleaning material used during each month; and the volume fraction of 
coating solids for each coating used during each month.
    (f) Calculate the total mass of organic HAP emissions before add-on 
controls. Using Equation 1 of Sec. 63.4751, calculate the total mass of 
organic HAP emissions before add-on controls from all coatings, 
thinners, and cleaning materials used during each month in the coating 
operation or group of coating operations for which you use the emission 
rate with add-on controls option.
    (g) Calculate the organic HAP emission reduction for each controlled 
coating operation. Determine the mass of organic HAP emissions reduced 
for each controlled coating operation during each month. The emission 
reduction determination quantifies the total organic HAP emissions that 
pass through the emission capture system and are destroyed or removed by 
the add-on control device. Use the procedures in paragraph (h) of this 
section to calculate the mass of organic HAP emission reduction for each 
controlled coating operation using an emission capture system and add-on 
control device other than a solvent recovery system for which you 
conduct liquid-liquid material balances. For each controlled coating 
operation using a solvent recovery system for which you conduct a 
liquid-liquid material balance, use the procedures in paragraph (j) of 
this section to calculate the organic HAP emission reduction.
    (h) Calculate the organic HAP emission reduction for each controlled 
coating operation not using liquid-liquid material balances. For each 
controlled coating operation using an emission capture system and add-on 
control device other than a solvent recovery system for which you 
conduct liquid-liquid material balances, calculate the organic

[[Page 788]]

HAP emission reduction, using Equation 1 of this section. The 
calculation applies the emission capture system efficiency and add-on 
control device efficiency to the mass of organic HAP contained in the 
coatings, thinners, and cleaning materials that are used in the coating 
operation served by the emission capture system and add-on control 
device during each month. For any period of time a deviation specified 
in Sec. 63.4763(c) or (d) occurs in the controlled coating operation, 
including a deviation during a period of SSM, you must assume zero 
efficiency for the emission capture system and add-on control device. 
Equation 1 of this section treats the materials used during such a 
deviation as if they were used on an uncontrolled coating operation for 
the time period of the deviation.

Compliance Status required by Sec. 63.4710, you must identify the 
coating operation(s) for which you used the emission rate with add-on 
controls option and submit a statement that the coating operation(s) was 
(were) in compliance with the emission limitations during the initial 
compliance period because the organic HAP emission rate was less than or 
equal to the applicable emission limit in Sec. 63.4690, and you 
achieved the operating limits required by Sec. 63.4692 and the work 
practice standards required by Sec. 63.4693.

[[Page 793]]



Sec. 63.4762  [Reserved]



Sec. 63.4763  How do I demonstrate continuous compliance with the
emission limitations?

    (a) To demonstrate continuous compliance with the applicable 
emission limit in Sec. 63.4690, the organic HAP emission rate for each 
compliance period, calculated using Equation 5 of Sec. 63.4761, must be 
equal to or less than the applicable emission limit in Sec. 63.4690. A 
compliance period consists of 12 months. Each month after the end of the 
initial compliance period described in Sec. 63.4760 is the end of a 
compliance period consisting of that month and the preceding 11 months. 
You must perform the calculations in Sec. 63.4761 on a monthly basis 
using data from the previous 12 months of operation.
    (b) If the organic HAP emission rate for any 12-month compliance 
period exceeded the applicable emission limit in Sec. 63.4690, this is 
a deviation from the emission limitation for that compliance period and 
must be reported as specified in Sec. Sec. 63.4710(c)(6) and 
63.4720(a)(7).
    (c) You must demonstrate continuous compliance with each operating 
limit required by Sec. 63.4692 that applies to you, as specified in 
Table 3 to this subpart.
    (1) If an operating parameter is out of the allowed range specified 
in Table 3 to this subpart, this is a deviation from the operating limit 
that must be reported as specified in Sec. Sec. 63.4710(c)(6) and 
63.4720(a)(7).
    (2) If an operating parameter deviates from the operating limit 
specified in Table 3 to this subpart, then you must assume that the 
emission capture system and add-on control device were achieving zero 
efficiency during the time period of the deviation. For the purposes of 
completing the compliance calculations specified in Sec. 63.4761(h), 
you must treat the materials used during a deviation on a controlled 
coating operation as if they were used on an uncontrolled coating 
operation for the time period of the deviation, as indicated in Equation 
1 of Sec. 63.4761.
    (d) You must meet the requirements for bypass lines in Sec. 
63.4768(b) for controlled coating operations for which you do not 
conduct liquid-liquid material balances. If any bypass line is opened 
and emissions are diverted to the atmosphere when a controlled coating 
operation is running, this is a deviation that must be reported as 
specified in Sec. Sec. 63.4710(c)(6) and 63.4720(a)(7). For the 
purposes of completing the compliance calculations specified in Sec. 
63.4761(h), you must treat the materials used during a deviation on a 
controlled coating operation as if they were used on an uncontrolled 
coating operation for the time period of the deviation, as indicated in 
Equation 1 of Sec. 63.4761.
    (e) You must demonstrate continuous compliance with the work 
practice standards in Sec. 63.4693. If you did not develop a work 
practice plan, or you did not implement the plan, or you did not keep 
the records required by Sec. 63.4730(k)(8), this is a deviation from 
the work practice standards that must be reported as specified in 
Sec. Sec. 63.4710(c)(6) and 63.4720(a)(7).
    (f) As part of each semiannual compliance report required in Sec. 
63.4720, you must identify the coating operation(s) for which you used 
the emission rate with add-on controls option. If there were no 
deviations from the emission limitations, submit a statement that you 
were in compliance with the emission limitations during the reporting 
period because the organic HAP emission rate for each compliance period 
was less than or equal to the applicable emission limit in Sec. 
63.4690, and you achieved the operating limits required by Sec. 63.4692 
and the work practice standards required by Sec. 63.4693 during each 
compliance period.
    (g) [Reserved]
    (h) Consistent with Sec. Sec. 63.6(e) and 63.7(e)(1), deviations 
that occur during a period of SSM of the emission capture system, add-on 
control device, or coating operation that may affect emission capture or 
control device efficiency are not violations if you demonstrate to the 
Administrator's satisfaction that you were operating in accordance with 
Sec. 63.6(e)(1). The Administrator will determine whether deviations 
that occur during a period you identify as an SSM are violations, 
according to the provisions in Sec. 63.6(e).
    (i) [Reserved]

[[Page 794]]

    (j) You must maintain records as specified in Sec. Sec. 63.4730 and 
63.4731.

Sec. 63.4764  What are the general requirements for performance tests?

    (a) You must conduct each performance test required by Sec. 63.4760 
according to the requirements in Sec. 63.7(e)(1) and under the 
conditions in this section unless you obtain a waiver of the performance 
test according to the provisions in Sec. 63.7(h).
    (1) Representative coating operation operating conditions. You must 
conduct the performance test under representative operating conditions 
for the coating operation. Operations during periods of SSM, and during 
periods of nonoperation do not constitute representative conditions. You 
must record the process information that is necessary to document 
operating conditions during the test and explain why the conditions 
represent normal operation.
    (2) Representative emission capture system and add-on control device 
operating conditions. You must conduct the performance test when the 
emission capture system and add-on control device are operating at a 
representative flow rate, and the add-on control device is operating at 
a representative inlet concentration. You must record information that 
is necessary to document emission capture system and add-on control 
device operating conditions during the test and explain why the 
conditions represent normal operation.
    (b) You must conduct each performance test of an emission capture 
system according to the requirements in Sec. 63.4765. You must conduct 
each performance test of an add-on control device according to the 
requirements in Sec. 63.4766.



Sec. 63.4765  How do I determine the emission capture system efficiency?

    You must use the procedures and test methods in this section to 
determine capture efficiency as part of the performance test required by 
Sec. 63.4760.
    (a) Assuming 100 percent capture efficiency. You may assume the 
capture system efficiency is 100 percent if both of the conditions in 
paragraphs (a)(1) and (2) of this section are met:
    (1) The capture system meets the criteria in Method 204 of appendix 
M to 40 CFR part 51 for a PTE and directs all the exhaust gases from the 
enclosure to an add-on control device.
    (2) All coatings, thinners, and cleaning materials used in the 
coating operation are applied within the capture system; coating solvent 
flash-off and coating, curing, and drying occurs within the capture 
system; and the removal or evaporation of cleaning materials from the 
surfaces they are applied to occurs within the capture system. For 
example, this criterion is not met if parts enter the open shop 
environment when being moved between a spray booth and a curing oven.
    (b) Measuring capture efficiency. If the capture system does not 
meet both of the criteria in paragraphs (a)(1) and (2) of this section, 
then you must use one of the three protocols described in paragraphs 
(c), (d), and (e) of this section to measure capture efficiency. The 
capture efficiency measurements use TVH capture efficiency as a 
surrogate for organic HAP capture efficiency. For the protocols in 
paragraphs (c) and (d) of this section, the capture efficiency 
measurement must consist of three test runs. Each test run must be at 
least 3 hours in duration or the length of a production run, whichever 
is longer, up to 8 hours. For the purposes of this test, a production 
run means the time required for a single part to go from the beginning 
to the end of production, which includes surface preparation activities 
and drying or curing time.
    (c) Liquid-to-uncaptured-gas protocol using a temporary total 
enclosure or building enclosure. The liquid-to-uncaptured-gas protocol 
compares the mass of liquid TVH in materials used in the coating 
operation to the mass of TVH emissions not captured by the emission 
capture system. Use a temporary total enclosure or a building enclosure 
and the procedures in paragraphs (c)(1) through (6) of this section to 
measure emission capture system efficiency using the liquid-to-
uncaptured-gas protocol.
    (1) Either use a building enclosure or construct an enclosure around 
the

[[Page 795]]

coating operation where coatings, thinners, and cleaning materials are 
applied, and all areas where emissions from these applied coatings and 
materials subsequently occur, such as flash-off, curing, and drying 
areas. The areas of the coating operation where capture devices collect 
emissions for routing to an add-on control device, such as the entrance 
and exit areas of an oven or spray booth, must also be inside the 
enclosure. The enclosure must meet the applicable definition of a 
temporary total enclosure or building enclosure in Method 204 of 
appendix M to 40 CFR part 51.
    (2) Use Method 204A or 204F of appendix M to 40 CFR part 51 to 
determine the mass fraction of TVH liquid input from each coating, 
thinner, and cleaning material used in the coating operation during each 
capture efficiency test run. To make the determination, substitute TVH 
for each occurrence of the term volatile organic compounds (VOC) in the 
methods.
    (3) Use Equation 1 of this section to calculate the total mass of 
TVH liquid input from all the coatings, thinners, and cleaning materials 
used in the coating operation during each capture efficiency test run.
[GRAPHIC] [TIFF OMITTED] TR98AD03.020

Where:

TVHused = Mass of liquid TVH in materials used in the coating 
          operation during the capture efficiency test run, grams.
TVHi = Mass fraction of TVH in coating, thinner, or cleaning 
          material, i, that is used in the coating operation during the 
          capture efficiency test run, grams TVH per gram material.

          material, i, used in the coating operation during the capture 
          efficiency test run, liters.

          grams material per liter material.
n = Number of different coatings, thinners, and cleaning materials used 
          in the coating operation during the capture efficiency test 
          run.

    (4) Use Method 204D or E of appendix M to 40 CFR part 51 to measure 
the total mass, grams, of TVH emissions that are not captured by the 
emission capture system; they are measured as they exit the temporary 
total enclosure or building enclosure during each capture efficiency 
test run. To make the measurement, substitute TVH for each occurrence of 
the term VOC in the methods.

    (i) Use Method 204D of appendix M to 40 CFR part 51 if the enclosure 
is a temporary total enclosure.
    (ii) Use Method 204E of appendix M to 40 CFR part 51 if the 
enclosure is a building enclosure. During the capture efficiency 
measurement, all organic compound emitting operations inside the 
building enclosure, other than the coating operation for which capture 
efficiency is being determined, must be shut down, but all fans and 
blowers must be operating normally.
    (5) For each capture efficiency test run, determine the percent 
capture efficiency of the emission capture system using Equation 2 of 
this section:
[GRAPHIC] [TIFF OMITTED] TR98AD03.021

Where:

CE = Capture efficiency of the emission capture system vented to the 
          add-on control device, percent.

[[Page 796]]

TVHused = Total mass of TVH liquid input used in the coating 
          operation during the capture efficiency test run, grams.

          total enclosure or building enclosure during the capture 
          efficiency test run, grams, determined according to paragraph 
          (c)(4) of this section.

    (6) Determine the capture efficiency of the emission capture system 
as the average of the capture efficiencies measured in the three test 
runs.
    (d) Gas-to-gas protocol using a temporary total enclosure or a 
building enclosure. The gas-to-gas protocol compares the mass of TVH 
emissions captured by the emission capture system to the mass of TVH 
emissions not captured. Use a temporary total enclosure or a building 
enclosure and the procedures in paragraphs (d)(1) through (5) of this 
section to measure emission capture system efficiency using the gas-to-
gas protocol.
    (1) Either use a building enclosure or construct an enclosure around 
the coating operation where coatings, thinners, and cleaning materials 
are applied, and all areas where emissions from these applied coatings 
and materials subsequently occur, such as flash-off, curing, and drying 
areas. The areas of the coating operation where capture devices collect 
emissions generated by the coating operation for routing to an add-on 
control device, such as the entrance and exit areas of an oven or a 
spray booth, must also be inside the enclosure. The enclosure must meet 
the applicable definition of a temporary total enclosure or building 
enclosure in Method 204 of appendix M to 40 CFR part 51.
    (2) Use Method 204B or 204C of appendix M to 40 CFR part 51 to 
measure the total mass, grams, of TVH emissions captured by the emission 
capture system during each capture efficiency test run as measured at 
the inlet to the add-on control device. To make the measurement, 
substitute TVH for each occurrence of the term VOC in the methods.
    (i) The sampling points for the Method 204B or 204C of appendix M to 
40 CFR part 51 measurement must be upstream from the add-on control 
device and must represent total emissions routed from the capture system 
and entering the add-on control device.
    (ii) If multiple emission streams from the capture system enter the 
add-on control device without a single common duct, then the emissions 
entering the add-on control device must be simultaneously measured in 
each duct, and the total emissions entering the add-on control device 
must be determined.
    (3) Use Method 204D or 204E of appendix M to 40 CFR part 51 to 
measure the total mass, grams, of TVH emissions that are not captured by 
the emission capture system; they are measured as they exit the 
temporary total enclosure or building enclosure during each capture 
efficiency test run. To make the measurement, substitute TVH for each 
occurrence of the term VOC in the methods.
    (i) Use Method 204D of appendix M to 40 CFR part 51 if the enclosure 
is a temporary total enclosure.
    (ii) Use Method 204E of appendix M to 40 CFR part 51 if the 
enclosure is a building enclosure. During the capture efficiency 
measurement, all organic compound emitting operations inside the 
building enclosure, other than the coating operation for which capture 
efficiency is being determined, must be shut down, but all fans and 
blowers must be operating normally.
    (4) For each capture efficiency test run, determine the percent 
capture efficiency of the emission capture system using Equation 3 of 
this section:
[GRAPHIC] [TIFF OMITTED] TR98AD03.022


[[Page 797]]


Where:

CE = Capture efficiency of the emission capture system vented to the 
          add-on control device, percent.
TVHcaptured = Total mass of TVH captured by the emission 
          capture system as measured at the inlet to the add-on control 
          device during the emission capture efficiency test run, grams, 
          determined according to paragraph (d)(2) of this section.
TVHuncaptured = Total mass of TVH that is not captured by the 
          emission capture system and that exits from the temporary 
          total enclosure or building enclosure during the capture 
          efficiency test run, grams, determined according to paragraph 
          (d)(3) of this section.

    (5) Determine the capture efficiency of the emission capture system 
as the average of the capture efficiencies measured in the three test 
runs.
    (e) Alternative capture efficiency protocol. As an alternative to 
the procedures specified in paragraphs (c) and (d) of this section, you 
may determine capture efficiency using any other capture efficiency 
protocol and test methods that satisfy the criteria of either the DQO or 
LCL approach as described in appendix A to subpart KK of this part.



Sec. 63.4766  How do I determine the add-on control device emission
destruction or removal efficiency?

    You must use the procedures and test methods in this section to 
determine the add-on control device emission destruction or removal 
efficiency as part of the performance test required by Sec. 63.4760. 
You must conduct three test runs as specified in Sec. 63.7(e)(3), and 
each test run must last at least 1 hour.
    (a) For all types of add-on control devices, use the test methods 
specified in paragraphs (a)(1) through (5) of this section.
    (1) Use Method 1 or 1A of appendix A to 40 CFR part 60, as 
appropriate, to select sampling sites and velocity traverse points.
    (2) Use Method 2, 2A, 2C, 2D, 2F, or 2G of appendix A to 40 CFR part 
60, as appropriate, to measure gas volumetric flow rate.
    (3) Use Method 3, 3A, or 3B of appendix A to 40 CFR part 60, as 
appropriate, for gas analysis to determine dry molecular weight. You may 
also use as an alternative to Method 3B, the manual method for measuring 
the oxygen, carbon dioxide, and carbon monoxide content of exhaust gas 
in ANSI/ASME PTC 19.10-1981, ``Flue and Exhaust Gas Analyses [Part 10, 
Instruments and Apparatus]'' (incorporated by reference, see Sec. 
63.14).
    (4) Use Method 4 of appendix A to 40 CFR part 60 to determine stack 
gas moisture.
    (5) Methods for determining gas volumetric flow rate, dry molecular 
weight, and stack gas moisture must be performed, as applicable, during 
each test run.
    (b) Measure total gaseous organic mass emissions as carbon at the 
inlet and outlet of the add-on control device simultaneously, using 
either Method 25 or 25A of appendix A to 40 CFR part 60, as specified in 
paragraphs (b)(1) through (3) of this section. You must use the same 
method for both the inlet and outlet measurements.
    (1) Use Method 25 of appendix A to 40 CFR part 60 if the add-on 
control device is an oxidizer, and you expect the total gaseous organic 
concentration as carbon to be more than 50 parts per million (ppm) at 
the control device outlet.
    (2) Use Method 25A of appendix A to 40 CFR part 60 if the add-on 
control device is an oxidizer, and you expect the total gaseous organic 
concentration as carbon to be 50 ppm or less at the control device 
outlet.
    (3) Use Method 25A of appendix A to 40 CFR part 60 if the add-on 
control device is not an oxidizer.
    (c) If two or more add-on control devices are used for the same 
emission stream, then you must measure emissions at the outlet of each 
device. For example, if one add-on control device is a concentrator with 
an outlet for the high-volume, dilute stream that has been treated by 
the concentrator, and a second add-on control device is an oxidizer with 
an outlet for the low-volume, concentrated stream that is treated with 
the oxidizer, you must measure emissions at the outlet of the oxidizer 
and the high volume dilute stream outlet of the concentrator.
    (d) For each test run, determine the total gaseous organic emissions 
mass flow rates for the inlet and the outlet of the add-on control 
device, using Equation 1 of this section. If there is

[[Page 798]]

more than one inlet or outlet to the add-on control device, you must 
calculate the total gaseous organic mass flow rate using Equation 1 of 
this section for each inlet and each outlet and then total all of the 
inlet emissions and total all of the outlet emissions.

          outlet(s) of the add-on control device, using Equation 1 of 
          this section, grams/h.

add-on control device as the average of the efficiencies determined in 
the three test runs and calculated in Equation 2 of this section.



Sec. 63.4767  How do I establish the emission capture system and
add-on control device operating limits during the performance test?

    During the performance test required by Sec. 63.4760 and described 
in Sec. Sec. 63.4764, 63.4765, and 63.4766, you must establish the 
operating limits required by Sec. 63.4692 according to this section, 
unless you have received approval for alternative monitoring and 
operating limits under Sec. 63.8(f) as specified in Sec. 63.4692.
    (a) Thermal oxidizers. If your add-on control device is a thermal 
oxidizer, establish the operating limits according to paragraphs (a)(1) 
and (2) of this section.
    (1) During the performance test, you must monitor and record the 
combustion temperature at least once every 15 minutes during each of the 
three test runs. You must monitor the temperature in the firebox of the 
thermal oxidizer or immediately downstream of the firebox before any 
substantial heat exchange occurs.
    (2) Use the data collected during the performance test to calculate 
and record the average combustion temperature maintained during the 
performance test. This average combustion temperature is the minimum 
operating limit for your thermal oxidizer.
    (b) Catalytic oxidizers. If your add-on control device is a 
catalytic oxidizer, establish the operating limits according to either 
paragraphs (b)(1) and (2) or paragraphs (b)(3) and (4) of this section.
    (1) During the performance test, you must monitor and record the 
temperature before the catalyst bed and the temperature difference 
across the catalyst bed at least once every 15 minutes during each of 
the three test runs.
    (2) Use the data collected during the performance test to calculate 
and record the average temperature difference across the catalyst bed 
maintained during the performance test. This is the minimum operating 
limit for your catalytic oxidizer.

[[Page 799]]

    (3) As an alternative to monitoring the temperature difference 
across the catalyst bed, you may monitor the temperature at the inlet to 
the catalyst bed and implement a site-specific inspection and 
maintenance plan for your catalytic oxidizer as specified in paragraph 
(b)(4) of this section. During the performance test, you must monitor 
and record the temperature before the catalyst bed at least once every 
15 minutes during each of the three test runs. Use the data collected 
during the performance test to calculate and record the average 
temperature before the catalyst bed during the performance test. This is 
the minimum operating limit for your catalytic oxidizer. (Note: For 
regenerative catalytic oxidizers, the inlet to the catalyst is defined 
as the general zone between the inlets to the catalyst beds located in 
the multiple regeneration towers; select either a monitoring location or 
multiple monitoring locations. If multiple monitoring locations are 
selected, either establish separate operating limits for each location 
or calculate an average of the multiple measurements and set a single 
operating limit.)
    (4) You must develop and implement an inspection and maintenance 
plan for your catalytic oxidizer(s) for which you elect to monitor 
according to paragraph (b)(3) of this section. The plan must address, at 
a minimum, the elements specified in paragraphs (b)(4)(i) through (iii) 
of this section.
    (i) Annual sampling and analysis of the catalyst activity (i.e, 
conversion efficiency) following the recommended procedures from the 
manufacturer, the catalyst supplier, or the catalyst test provider.
    (ii) Monthly inspection of the oxidizer system, including the burner 
assembly and fuel supply lines for problems and, as necessary, adjust 
the equipment to assure proper air-to-fuel mixtures.
    (iii) Annual internal and monthly external visual inspection of the 
catalyst bed to check for channeling, abrasion, and settling. If 
problems are found, you must take corrective action consistent with the 
manufacturer's recommendation and conduct a new performance test to 
determine destruction efficiency according to Sec. 63.4766.
    (c) Carbon adsorbers. If your add-on control device is a carbon 
adsorber, establish the operating limits according to paragraphs (c)(1) 
and (2) of this section.
    (1) You must monitor and record the total regeneration desorbing gas 
(e.g., steam or nitrogen) mass flow for each regeneration cycle, and the 
carbon bed temperature after each carbon bed regeneration and cooling 
cycle for the regeneration cycle either immediately preceding or 
immediately following the performance test.
    (2) The operating limits for your carbon adsorber are the minimum 
total desorbing gas mass flow recorded during the regeneration cycle, 
and the maximum carbon bed temperature recorded after the cooling cycle.
    (d) Condensers. If your add-on control device is a condenser, 
establish the operating limits according to paragraphs (d)(1) and (2) of 
this section.
    (1) During the performance test, you must monitor and record the 
condenser outlet (product side) gas temperature at least once every 15 
minutes during each of the three test runs.
    (2) Use the data collected during the performance test to calculate 
and record the average condenser outlet (product side) gas temperature 
maintained during the performance test. This average condenser outlet 
gas temperature is the maximum operating limit for your condenser.
    (e) Concentrators. If your add-on control device includes a 
concentrator, you must establish operating limits for the concentrator 
according to paragraphs (e)(1) through (4) of this section.
    (1) During the performance test, you must monitor and record the 
desorption concentrate stream gas temperature at least once every 15 
minutes during each of the three runs of the performance test.
    (2) Use the data collected during the performance test to calculate 
and record the average temperature. This is the minimum operating limit 
for the desorption concentrate gas stream temperature.
    (3) During the performance test, you must monitor and record the 
pressure drop of the dilute stream across the concentrator at least once 
every 15

[[Page 800]]

minutes during each of the three runs of the performance test.
    (4) Use the data collected during the performance test to calculate 
and record the average pressure drop. This is the maximum operating 
limit for the dilute stream across the concentrator.
    (f) Emission capture system. For each capture device that is not 
part of a PTE that meets the criteria of Sec. 63.4765(a), establish an 
operating limit for either the gas volumetric flow rate or duct static 
pressure, as specified in paragraphs (f)(1) and (2) of this section. The 
operating limit for a PTE is specified in Table 3 to this subpart.
    (1) During the capture efficiency determination required by Sec. 
63.4760 and described in Sec. Sec. 63.4764 and 63.4765, you must 
monitor and record either the gas volumetric flow rate or the duct 
static pressure for each separate capture device in your emission 
capture system at least once every 15 minutes during each of the three 
test runs at a point in the duct between the capture device and the add-
on control device inlet.
    (2) Calculate and record the average gas volumetric flow rate or 
duct static pressure for the three test runs for each capture device. 
This average gas volumetric flow rate or duct static pressure is the 
minimum operating limit for that specific capture device.



Sec. 63.4768  What are the requirements for continuous parameter
monitoring system installation, operation, and maintenance?

    (a) General. You must install, operate, and maintain each CPMS 
specified in paragraphs (c), (e), (f), and (g) of this section according 
to paragraphs (a)(1) through (6) of this section. You must install, 
operate, and maintain each CPMS specified in paragraphs (b) and (d) of 
this section according to paragraphs (a)(3) through (5) of this section.
    (1) The CPMS must complete a minimum of one cycle of operation for 
each successive 15-minute period. You must have a minimum of four 
equally spaced successive cycles of CPMS operation in 1 hour.
    (2) You must determine the average of all recorded readings for each 
successive 3-hour period of the emission capture system and add-on 
control device operation.
    (3) You must record the results of each inspection, calibration, and 
validation check of the CPMS.
    (4) You must maintain the CPMS at all times and have available 
necessary parts for routine repairs of the monitoring equipment.
    (5) You must operate the CPMS and collect emission capture system 
and add-on control device parameter data at all times that a controlled 
coating operation is operating, except during monitoring malfunctions, 
associated repairs, and required quality assurance or control activities 
(including, if applicable, calibration checks and required zero and span 
adjustments).
    (6) You must not use emission capture system or add-on control 
device parameter data recorded during periods when the control device is 
not receiving emissions, monitoring malfunctions, associated repairs, 
out-of-control periods, or required quality assurance or control 
activities when calculating data averages. You must use all the data 
collected during all other periods in calculating the data averages for 
determining compliance with the emission capture system and add-on 
control device operating limits.
    (7) A monitoring malfunction is any sudden, infrequent, not 
reasonably preventable failure of the CPMS to provide valid data. 
Monitoring failures that are caused in part by poor maintenance or 
careless operation are not malfunctions. Any period for which the 
monitoring system is out-of-control and data are not available for 
required calculations is a deviation from the monitoring requirements.
    (b) Capture system bypass line. You must meet the requirements of 
paragraphs (b)(1) and (2) of this section for each emission capture 
system that contains bypass lines that could divert emissions away from 
the add-on control device to the atmosphere.
    (1) You must monitor or secure the valve or closure mechanism 
controlling the bypass line in a nondiverting position in such a way 
that the valve or closure mechanism cannot be opened without creating a 
record that the valve was opened. The method used to monitor or secure 
the valve or closure

[[Page 801]]

mechanism must meet one of the requirements specified in paragraphs 
(b)(1)(i) through (iv) of this section.
    (i) Flow control position indicator. Install, calibrate, maintain, 
and operate according to the manufacturer's specifications a flow 
control position indicator that takes a reading at least once every 15 
minutes and provides a record indicating whether the emissions are 
directed to the add-on control device or diverted from the add-on 
control device. The time of occurrence and flow control position must be 
recorded, as well as every time the flow direction is changed. The flow 
control position indicator must be installed at the entrance to any 
bypass line that could divert the emissions away from the add-on control 
device to the atmosphere.
    (ii) Car-seal or lock-and-key valve closures. Secure any bypass line 
valve in the closed position with a car-seal or a lock-and-key type 
configuration. You must visually inspect the seal or closure mechanism 
at least once every month to ensure that the valve is maintained in the 
closed position, and the emissions are not diverted away from the add-on 
control device to the atmosphere.
    (iii) Valve closure monitoring. Ensure that any bypass line valve is 
in the closed (non-diverting) position through monitoring of valve 
position at least once every 15 minutes. You must inspect the monitoring 
system at least once every month to verify that the monitor will 
indicate valve position.
    (iv) Automatic shutdown system. Use an automatic shutdown system in 
which the coating operation is stopped when flow is diverted by the 
bypass line away from the add-on control device to the atmosphere when 
the coating operation is running. You must inspect the automatic 
shutdown system at least once every month to verify that it will detect 
diversions of flow and shut down the coating operation.
    (2) If any bypass line is opened and there was a deviation from the 
applicable emission limitation, you must include a description of why 
the bypass line was opened and the length of time it remained open in 
the semiannual compliance reports required in Sec. 63.4720.
    (c) Thermal oxidizers and catalytic oxidizers. If you are using a 
thermal oxidizer or catalytic oxidizer as an add-on control device 
(including those used with concentrators or with carbon adsorbers to 
treat desorbed concentrate streams), you must comply with the 
requirements in paragraphs (c)(1) through (3) of this section:
    (1) For a thermal oxidizer, install a gas temperature monitor in the 
firebox of the thermal oxidizer or in the duct immediately downstream of 
the firebox before any substantial heat exchange occurs.
    (2) For a catalytic oxidizer, you must install a gas temperature 
monitor in the gas stream immediately before the catalyst bed, and if 
you established operating limits according to Sec. 63.4767(b)(1) and 
(2), also install a gas temperature monitor in the gas stream 
immediately after the catalyst bed.
    (i) If you establish operating limits according to Sec. 
63.4767(b)(1) and (2), then you must install the gas temperature 
monitors both upstream and downstream of the catalyst bed. The 
temperature monitors must be in the gas stream immediately before and 
after the catalyst bed to measure the temperature difference across the 
bed.
    (ii) If you establish operating limits according to Sec. 
63.4767(b)(3) and (4), then you must install a gas temperature monitor 
upstream of the catalyst bed. The temperature monitor must be in the gas 
stream immediately before the catalyst bed to measure the temperature.

that is delivered to an add-on control device.
    Capture system means one or more capture devices intended to collect 
emissions generated by a coating operation in the use of coatings or 
cleaning materials, both at the point of application and at subsequent 
points where emissions from the coatings or cleaning materials occur, 
such as flashoff, drying, or curing. As used in this subpart, multiple 
capture devices that collect emissions generated by a coating operation 
are considered a single capture system.

[[Page 804]]

    Cleaning material means a solvent used to remove contaminants and 
other materials, such as dirt, grease, oil, and dried or wet coating 
(e.g., depainting), from a substrate before or after coating application

operation may include any combination of these types of equipment, but 
always includes at least the point at which a coating or cleaning 
material is applied and all subsequent points in the affected source 
where organic HAP emissions from that coating or cleaning material 
occur. There may be multiple coating operations in an affected source.

subpart including, but not limited to any emission limit, or operating 
limit, or work practice standard;
    (2) Fails to meet any term or condition that is adopted to implement 
an applicable requirement in this subpart and that is included in the 
operating permit for any affected source required to obtain such a 
permit; or
    (3) Fails to meet any emission limit, or operating limit, or work 
practice standard in this subpart during SSM, regardless of whether or 
not such failure is permitted by this subpart.
    Emission limitation means an emission limit, operating limit, or 
work practice standard.
    Enclosure means a structure that surrounds a source of emissions and

VOC due to negligible photochemical reactivity. The exempt compounds are 
listed in 40 CFR 51.100(s).
    Finished wood product means any wood building product to which a 
protective, decorative, or functional layer has been applied. Materials 
used include, but are not limited to, paints, stains, sealers, topcoats, 
basecoats, primers, enamels, inks, and adhesives.
    Laminated wood product means any wood building product to which a 
protective, decorative, or functional layer has been bonded with an 
adhesive. Products that are produced by bonding layers to the substrate 
as a part of the substrate manufacturing process (prior to pressing) are 
not considered laminated products under this subpart.
    Manufacturer's formulation data means data on a material (such as a 
coating) that are supplied by the material manufacturer based on 
knowledge of the ingredients used to manufacture that material, rather 
than based on testing of the material with the test

HAP to the mass of a material in which it is contained, expressed as 
grams of organic HAP per gram of material.
    Millwork means lumber that has been remanufactured into a wood 
building product or component such as door, window, and staircase 
part(s), or decorative trim.
    Month means a calendar month or a pre-specified period of 28 days to 
35 days to allow for flexibility in recordkeeping when data are based on 
a business accounting period.
    Organic HAP content means the mass of organic HAP per volume of 
coating solids for a coating calculated using Equation 2 of Sec. 
63.4741. The organic HAP content is determined for the coating in the

 Subpart RRRR_National Emission Standards for Hazardous Air Pollutants: 
                   Surface Coating of Metal Furniture

    Source: 68 FR 28619, May 23, 2003, unless otherwise noted.

                        What This Subpart Covers



Sec. 63.4880  What is the purpose of this subpart?

    This subpart establishes national emission standards for hazardous 
air pollutants (NESHAP) for metal furniture surface coating facilities. 
This subpart also establishes requirements to demonstrate initial and 
continuous compliance with the emission limitations.



Sec. 63.4881  Am I subject to this subpart?

    (a) Except as provided in paragraph (c) of this section, the source 
category to which this subpart applies is surface coating of metal 
furniture.
    (1) Surface coating is the application of coatings to a substrate 
using, for example, spray guns or dip tanks.
    (2) Metal furniture means furniture or components of furniture 
constructed either entirely or partially from metal. Metal furniture 
includes, but is not limited to, components of the following types of 
products as well as the products themselves: household, office, 
institutional, laboratory, hospital, public building, restaurant, barber 
and beauty shop, and dental furniture; office and store fixtures; 
partitions; shelving; lockers; lamps and lighting fixtures; and 
wastebaskets.
    (b) You are subject to this subpart if you own or operate a new, 
reconstructed, or existing affected source as defined in Sec. 63.4882, 
in the source category defined in paragraph (a) of this section, and 
that is a major source, is located at a major source, or is part of a 
major source of emissions of hazardous air pollutants (HAP). A major 
source of HAP emissions is any stationary source or group of stationary 
sources located within a contiguous area and under common control that 
emits or has the potential to emit any single HAP at a rate of 9.07 
megagrams (Mg) (10 tons) or more per year or any combination of HAP at a 
rate of 22.68 Mg (25 tons) or more per year.

[[Page 812]]

    (c) This subpart does not apply to surface coating that meets any of 
the criteria of paragraphs (c)(1) through (6) of this section.
    (1) Surface coating conducted at an affected source that uses only 
coatings, thinners, and cleaning materials that contain no organic HAP.
    (2) Surface coating of metal components of wood furniture conducted 
in an operation that is subject to the wood furniture manufacturing 
NESHAP in subpart JJ of this part.
    (3) Surface coating that occurs at research or laboratory facilities 
or that is part of janitorial, building, and facility maintenance 
operations.
    (4) Surface coating of only small items such as knobs, hinges, or 
screws that have a wider use beyond metal furniture are not subject to 
this subpart unless the surface coating occurs at an affected metal 
furniture source.
    (5) Surface coating of metal furniture conducted for the purpose of 
repairing or maintaining metal furniture used by a major source and not 
for commerce is not subject to this subpart, unless organic HAP 
emissions from the surface coating itself are as high as the rates 
specified in paragraph (b) of this section.
    (6) Surface coating of metal furniture performed on-site at 
installations owned or operated by the Armed Forces of the United States 
(including the Coast Guard and the National Guard of any State).



Sec. 63.4882  What parts of my plant does this subpart cover?

    (a) This subpart applies to each new, reconstructed, and existing 
affected source.
    (b) The affected source is the collection of all of the items listed 
in paragraphs (b)(1) through (4) of this section that are used for 
surface coating of metal furniture:
    (1) All coating operations as defined in Sec. 63.4981;
    (2) All storage containers and mixing vessels in which coatings, 
thinners, and cleaning materials are stored or mixed;
    (3) All manual and automated equipment and containers and all pumps 
and piping within the affected source used for conveying coatings, 
thinners, and cleaning materials; and
    (4) All storage containers, all pumps and piping, and all manual and 
automated equipment and containers within the affected source used for 
conveying waste materials generated by a coating operation.
    (c) An affected source is a new affected source if you commenced its 
construction after April 24, 2002, and the construction is of a 
completely new metal furniture surface coating facility where previously 
no metal furniture surface coating facility had existed.
    (d) An affected source is reconstructed if you meet the criteria as 
defined in Sec. 63.2.
    (e) An affected source is existing if it is not new or 
reconstructed.



Sec. 63.4883  When do I have to comply with this subpart?

    The date by which you must comply with this subpart is called the 
compliance date. The compliance date for each type of affected source is 
specified in paragraphs (a) through (c) of this section. The compliance 
date begins the initial compliance period during which you conduct the 
initial compliance demonstration described in Sec. Sec. 63.4940, 
63.4950, and 63.4960.
    (a) For a new or reconstructed affected source, the compliance date 
is the applicable date in paragraph (a)(1) or (2) of this section:
    (1) If the initial startup of your new or reconstructed affected 
source is before May 23, 2003, the compliance date is May 23, 2003.
    (2) If the initial startup of your new or reconstructed affected 
source occurs after May 23, 2003, the compliance date is the date of 
initial startup of your affected source.
    (b) For an existing affected source, the compliance date is the date 
3 years after May 23, 2003.
    (c) For an area source that increases its emissions or its potential 
to emit such that it becomes a major source of HAP emissions, the 
compliance date is specified in paragraphs (c)(1) and (2) of this 
section.
    (1) For any portion of the source that becomes a new or 
reconstructed affected source subject to this subpart, the compliance 
date is the date of initial startup of the affected source or May 23, 
2003, whichever is later.

[[Page 813]]

    (2) For any portion of the source that becomes an existing affected 
source subject to this subpart, the compliance date is the date 1 year 
after the area source becomes a major source or 3 years after May 23, 
2003, whichever is later.
    (d) You must meet the notification requirements in Sec. 63.4910 
according to the dates specified in that section and in subpart A of 
this part. Some of the notifications must be submitted before the 
compliance dates described in paragraphs (a) through (c) of this 
section.

                          Emission Limitations



Sec. 63.4890  What emission limits must I meet?

    (a) For a new or reconstructed affected source, you must emit no 
organic HAP during each compliance period, determined according to the 
procedures in Sec. 63.4941.
    (b) Alternative emission limit. You may request approval from the 
Administrator to use an alternative new source emission limit for 
specific metal furniture components or type of components for which you 
believe the emission limit in paragraph (a) of this section cannot be 
achieved.
    (1) Any request to use an alternative emission limit under paragraph 
(b) of this section must contain specific information demonstrating why 
no organic HAP-free coating technology can be used on the metal 
furniture components. The request must be based on objective criteria 
related to the performance or appearance requirements of the finished 
coating, which may include but is not limited to the criteria listed in 
paragraphs (b)(1)(i) through (viii) of this section.
    (i) Low dried film thickness requirements (e.g., less than 0.0254 
millimeters (0.001 inch)).
    (ii) Flexibility requirements for parts subject to repeated bending.
    (iii) Chemical resistance to withstand chemical exposure in 
environments such as laboratories.
    (iv) Resistance to the effects of exposure to ultraviolet light.
    (v) Adhesion characteristics related to the condition of the 
substrate.
    (vi) High gloss requirements.
    (vii) Custom colors such as matching the color of a corporate logo.
    (viii) Non-uniform surface finishes such as an antique appearance 
that requires visible cracking of the dried film.
    (2) If the request to use an alternative emission limit under 
paragraph (b) of this section is approved, the new source must meet an 
emission limit of 0.094 kilogram (kg) organic HAP per liter (kg/liter) 
(0.78 pounds per gallon (lb/gal)) coating solids used for only those 
components subject to the approval. All other metal furniture surface 
coating operations at the new source must meet the emission limit 
specified in paragraph (a) of this section. Until approval to use the 
alternative emission limit has been granted by the Administrator under 
this paragraph (b)(2), you must meet the emission limit specified in 
paragraph (a) of this section and all other applicable requirements in 
this subpart.
    (c) For an existing affected source, you must limit organic HAP 
emissions to the atmosphere to no more than 0.10 kg organic HAP per 
liter (0.83 lb/gal) of coating solids used during each compliance 
period, determined according to the procedures in Sec. 63.4941, Sec. 
63.4951, or Sec. 63.4961.



Sec. 63.4891  What are my options for demonstrating compliance with
the emission limits?

    You must include all coatings, thinners, and cleaning materials used 
in the affected source when determining whether the organic HAP emission 
rate is equal to or less than the applicable emission limit in Sec. 
63.4890. To make this determination, you must use at least one of the 
three compliance options listed in paragraphs (a) through (c) of this 
section. You may apply any of the compliance options to an individual 
coating operation or to multiple coating operations as a group or to the 
entire affected source. You may use different compliance options for 
different coating operations or at different times on the same coating 
operation. However, you may not use different compliance options at the 
same time on the same coating operation. If you switch between 
compliance options for any coating operation or group of coating 
operations, you must document this switch as required by

[[Page 814]]

Sec. 63.4930(c), and you must report it in the next semiannual (6-month 
period) compliance report required in Sec. 63.4920.
    (a) Compliant material option. Demonstrate that the organic HAP 
content of each coating used in the coating operation or group of 
coating operations is less than or equal to the applicable emission rate 
limit in Sec. 63.4890 and that each thinner and each cleaning material 
used contains no organic HAP. You must meet all the requirements of 
Sec. Sec. 63.4940, 63.4941, and 63.4942 to demonstrate compliance with 
the emission limit using this option.
    (b) Emission rate without add-on controls option. Demonstrate that, 
based on the coatings, thinners, and cleaning materials used in the 
coating operation or group of coating operations, the organic HAP 
emission rate for the coating operation or group of coating operations 
is less than or equal to the applicable emission rate limit in Sec. 
63.4890, calculated as a monthly emission rate. You must meet all the 
requirements of Sec. Sec. 63.4950, 63.4951, and 63.4952 to demonstrate 
compliance with the emission rate limit using this option.
    (c) Emission rate with add-on controls option. Demonstrate that, 
based on the coatings, thinners, and cleaning materials used in the 
coating operation or group of coating operations, and the emission 
reductions achieved by emission capture and add-on control systems, the 
organic HAP emission rate is less than or equal to the applicable 
emission rate limit in Sec. 63.4890, calculated as a monthly emission 
rate. If you use this compliance option, you must also demonstrate that 
all capture systems and add-on control devices for the coating operation 
or group of coating operations meet the operating limits required in 
Sec. 63.4892, except for solvent recovery systems for which you conduct 
liquid-liquid material balances according to Sec. 63.4961(j); and that 
you meet the work practice standards required in Sec. 63.4893. You must 
meet all the requirements of Sec. Sec. 63.4960 through 63.4967 to 
demonstrate compliance with the emission limits, operating limits, and 
work practice standards using this option.
    (d) If you choose to use the emission rate with add-on controls 
compliance option in paragraph (c) of this section and operate the 
coating operation, its emission capture system, or its add-on control 
device at multiple sets of representative operating conditions that 
result in different capture system or add-on control device efficiencies 
during a compliance period, you must follow one of the procedures in 
paragraph (d)(1) or (2) of this section.
    (1) Determine the operating conditions that result in the lowest 
emission capture system and add-on control device efficiencies through 
performance testing conducted according to Sec. Sec. 63.4963, 63.4964, 
and 63.4965. Use these emission capture system and add-on control device 
efficiencies for all representative operating conditions during the 
compliance period.
    (2) Develop a compliance calculation procedure for determining the 
organic HAP emission rate for the compliance period that takes into 
account all of the representative operating conditions the source was 
operated under during the compliance period and submit the procedure to 
the Administrator for approval. Until you receive approval from the 
Administrator, you must determine compliance according to paragraph (c) 
of this section.



Sec. 63.4892  What operating limits must I meet?

    (a) For any coating operation or group of coating operations for 
which you use the compliant material option or the emission rate without 
add-on controls option to demonstrate compliance, you are not required 
to meet any operating limits.
    (b) For any coating operation or group of coating operations for 
which you use the emission rate with add-on controls option to 
demonstrate compliance, except those for which you use a solvent 
recovery system and conduct a liquid-liquid material balance according 
to Sec. 63.4961(j), you must meet the operating limits specified in 
Table 1 to this subpart. These operating limits apply to the emission 
capture and control systems on the coating operation or group of coating 
operations for which you use emission capture and add-on controls to 
demonstrate compliance. You must establish the operating limits during 
the performance test according to the requirements in Sec. 63.4966.

[[Page 815]]

You must meet the operating limits at all times after you establish 
them.
    (c) If you use an add-on control device other than those listed in 
Table 1 to this subpart, or wish to monitor an alternative parameter and 
comply with a different operating limit, you must apply to the 
Administrator for approval of alternative monitoring under Sec. 
63.8(f).



Sec. 63.4893  What work practice standards must I meet?

    (a) For any coating operation or group of coating operations for 
which you use the compliant material option or the emission rate without 
add-on controls option to demonstrate compliance, you are not required 
to meet any work practice standards.
    (b) For any coating operation or group of coating operations for 
which you use the emission rate with add-on controls option to 
demonstrate compliance, you must develop and implement a work practice 
plan to minimize organic HAP emissions from the storage, mixing, and 
conveying of coatings, thinners, and cleaning materials used in, and 
waste materials generated by, the coating operation or group of coating 
operations for which you use this option; or you must meet an 
alternative standard as provided in paragraph (c) of this section. The 
plan must specify practices and procedures to ensure that, at a minimum, 
the elements specified in paragraphs (b)(1) through (5) of this section 
are implemented.
    (1) All organic-HAP-containing coatings, thinners, cleaning 
materials, and waste materials must be stored in closed containers. You 
must ensure that these containers are kept closed at all times except 
when depositing or removing these materials from the container.
    (2) Spills of organic-HAP-containing coatings, thinners, cleaning 
materials, and waste materials must be minimized.
    (3) Organic-HAP-containing coatings, thinners, cleaning materials, 
and waste materials must be conveyed from one location to another in 
closed containers or pipes.
    (4) Mixing vessels which contain organic-HAP-containing coatings and 
other materials must be closed except when adding to, removing, or 
mixing the contents.
    (5) Emissions of organic HAP must be minimized during cleaning of 
storage, mixing, and conveying equipment.
    (c) As provided in Sec. 63.6(g), the Administrator may choose to 
grant you permission to use an alternative to the work practice 
standards in this section.

                     General Compliance Requirements



Sec. 63.4900  What are my general requirements for complying with 
this subpart?

    (a) The affected source must be in compliance at all times with the 
emission limitations specified in Sec. 63.4890.
    (b) You must always operate and maintain your affected source, 
including all air pollution control and monitoring equipment you use for 
purposes of complying with this subpart, according to the provisions in 
Sec. 63.6(e)(1)(i).
    (c) If your affected source uses an emission capture system and add-
on control device to comply with the emission limitations in Sec. 
63.4890, you must develop a written startup, shutdown, and malfunction 
plan (SSMP) according to the provisions in Sec. 63.6(e)(3). The SSMP 
must address the startup, shutdown, and corrective actions in the event 
of a malfunction of the emission capture system or the add-on control 
device. The SSMP must also address any coating operation equipment that 
may cause increased emissions or that would affect capture efficiency if 
the process equipment malfunctions, such as conveyors that move parts 
among enclosures.

established dates for submitting 6-month monitoring reports pursuant to 
40 CFR 70.6(a)(3)(iii)(A) or 40 CFR 71.6(a)(3)(iii)(A), you may submit 
the first and subsequent semiannual compliance reports according to the 
dates the permitting authority has established for the 40 CFR part 70 or 
40 CFR part 71 6-month monitoring reports instead of according to the 
dates specified in paragraph (a)(1)(iii) of this section. However, under 
no circumstances shall the semiannual compliance report be submitted 
more than 30 days after the end of the semiannual reporting period 
established in paragraphs (a)(1)(i) and (ii) of this section.

    (c) You must keep each record on-site for at least 2 years after the 
date of each occurrence, measurement, maintenance, corrective action, 
report, or record, according to Sec. 63.10(b)(1). You may keep these 
records off-site for the remaining 3 years. You must keep records on-
site pertaining to the design and manufacturer's specifications for 
operation of add-on control equipment for the life of the equipment.

        Compliance Requirements for the Compliant Material Option



Sec. 63.4940  By what date must I conduct the initial compliance
demonstration?

    You must complete the initial compliance demonstration for the 
initial compliance period according to the requirements in Sec. 
63.4941. The initial compliance period begins on the applicable 
compliance date specified in Sec. 63.4883 and ends on the last day of 
the first full month following the compliance date. The initial 
compliance demonstration includes the calculations according to Sec. 
63.4941 and supporting documentation showing that, during the initial 
compliance period, you used no coating with an organic HAP content that 
exceeded the applicable emission limit in Sec. 63.4890, and you used no 
thinners or cleaning materials that contained organic HAP.



Sec. 63.4941  How do I demonstrate initial compliance with the
emission limitations?

    You may use the compliant material option for any individual coating 
operation, for any group of coating operations in the affected source, 
or for all the coating operations in the affected source to demonstrate 
compliance with an organic HAP emission limit. You must use either the 
emission rate without add-on controls option or the emission rate with 
add-on controls option for any coating operation in the affected source 
for which you do not use this option. To demonstrate initial compliance 
using the compliant material option, during the compliance period the 
coating operation or group of coating operations must use no coating 
with an organic HAP content that exceeds the applicable emission limit 
in Sec. 63.4890 and must use no thinner or cleaning material that 
contains organic HAP as determined according to this section. Any 
coating operation for which you use the compliant material option is not 
required to comply with the operating limits or work practice standards 
required in Sec. Sec. 63.4892 and 63.4893, respectively. To demonstrate 
initial compliance with the emission limitations using the compliant 
material option, you must meet all the requirements of this section for 
the coating operation or group of coating operations using this option. 
Use the procedures in this section for each coating, thinner, and 
cleaning material in the condition it is in when it is received from its 
manufacturer or supplier and prior to any alteration. You do not need to 
redetermine the organic HAP content of cleaning materials that are 
reclaimed and reused onsite provided these materials in their condition 
as received were demonstrated to comply with the compliant material 
option.
    (a) Determine the mass fraction of organic HAP for each material 
used. You must determine the mass fraction of organic HAP for each 
coating, thinner, and cleaning material used during the

[[Page 824]]

compliance period by using one of the options in paragraphs (a)(1) 
through (5) of this section.
    (1) Method 311 (appendix A to 40 CFR part 63). You may use Method 
311 for determining the mass fraction of organic HAP. Use the procedures 
specified in paragraphs (a)(1)(i) and (ii) of this section when 
performing a Method 311 test.
    (i) Count each organic HAP that is measured to be present at 0.1 
percent by mass or more for Occupational Safety and Health 
Administration (OSHA)-defined carcinogens as specified in 29 CFR 
1910.1200(d)(4) and at 1.0 percent by mass or more for other organic HAP 
compounds. For example, if toluene (not an OSHA carcinogen) is measured 
to be 0.5 percent of the material by mass, you do not have to count it. 
Express the mass fraction of each organic HAP you count as a value 
truncated to four places after the decimal point (for example, 0.3791).
    (ii) Calculate the total mass fraction of organic HAP in the test 
material by adding up the individual organic HAP mass fractions and 
truncating the result to three places after the decimal point (for 
example, 0.763).
    (2) Method 24 (appendix A to 40 CFR part 60). For coatings, you may 
use Method 24 to determine the mass fraction of nonaqueous volatile 
matter and use that value as a substitute for mass fraction of organic 
HAP.
    (3) Alternative method. You may use an alternative test method for 
determining the mass fraction of organic HAP once the Administrator has 
approved it. You must follow the procedure in Sec. 63.7(f) to submit an 
alternative test method for approval.
    (4) Information from the supplier or manufacturer of the material. 
You may rely on information other than that generated by the test 
methods specified in paragraphs (a)(1) through (3) of this section, such 
as manufacturer's formulation data, if it represents each organic HAP 
that is present at 0.1 percent by mass or more for OSHA-defined 
carcinogens as specified in 29 CFR 1910.1200(d)(4) and at 1.0 percent by 
mass or more for other organic HAP compounds. For example, if toluene 
(not an OSHA carcinogen) is 0.5 percent of the material by mass, you do 
not have to count it. If there is a disagreement between such 
information and results of a test conducted according to paragraphs 
(a)(1) through (3) of this section, then the test method results will 
take precedence.
    (5) Solvent blends. Solvent blends may be listed as single 
components for some materials in data provided by manufacturers or 
suppliers. Solvent blends may contain organic HAP which must be counted 
toward the total organic HAP mass fraction of the materials. When test 
data and manufacturer's data for solvent blends are not available, you 
may use the default values for the mass fraction of organic HAP in these 
solvent blends listed in Table 3 or 4 to this subpart. If you use the 
tables, you must use the values in Table 3 for all solvent blends that 
match Table 3 entries, and you may only use Table 4 if the solvent 
blends in the materials you use do not match any of the solvent blends 
in Table 3, and you only know whether the blend is aliphatic or 
aromatic. However, if the results of a Method 311 test indicate higher 
values than those listed on Table 3 or 4 of this subpart, the Method 311 
results will take precedence.
    (b) Determine the volume fraction of coating solids for each 
coating. You must determine the volume fraction of coating solids 
(liters of coating solids per liter of coating) for each coating used 
during the compliance period by a test or by information provided by the 
supplier or the manufacturer of the material, as specified in paragraphs 
(b)(1), (2), and (3) of this section. If test results obtained according 
to paragraph (b)(1) of this section do not agree with the information 
obtained under paragraph (b)(2) or (3) of this section, the test results 
will take precedence.
    (1) Test results. You may use ASTM Method D2697-86 (Reapproved 
1998), ``Standard Test Method for Volume Nonvolatile Matter in Clear or 
Pigmented Coatings'' (incorporated by reference, see Sec. 63.14), or 
D6093-97, ``Standard Test Method for Percent Volume Nonvolatile Matter 
in Clear or Pigmented Coatings Using a Helium Gas Pycnometer'' 
(incorporated by reference, see Sec. 63.14), to determine the volume 
fraction of coating solids for each coating. Divide the nonvolatile

[[Page 825]]

volume percent obtained with the methods by 100 to calculate volume 
fraction of coating solids. Alternatively, you may use another test 
method once you obtain approval from the Administrator according to the 
requirements of Sec. 63.7(f).
    (2) Information from the supplier or manufacturer of the material. 
You may obtain the volume fraction of coating solids for each coating 
from the supplier or manufacturer.
    (3) Calculation of volume fraction of coating solids. If the volume 
fraction of coating solids cannot be determined using the options in 
paragraphs (b)(1) and (2) of this section, you must determine it using 
Equation 1 of this section:
[GRAPHIC] [TIFF OMITTED] TR23MY03.019

Where:

Vs = Volume fraction of coating solids, liters coating solids 
          per liter coating.
Mvolatiles = Total volatile matter content of the coating, 
          including HAP, volatile organic compounds (VOC), water, and 
          exempt compounds, determined according to Method 24 in 
          appendix A of 40 CFR part 60, grams volatile matter per liter 
          coating.
Davg = Average density of volatile matter in the coating, 
          grams volatile matter per liter volatile matter, determined 
          from test results using ASTM Method D1475-90, information from 
          the supplier or manufacturer of the material, or reference 
          sources providing density or specific gravity data for pure 
          materials. If there is disagreement between ASTM Method D1475-
          90 test results and other information sources, the test 
          results will take precedence.

    (c) Determine the density of each coating. You must determine the 
density of each coating used during the compliance period from test 
results using ASTM Method D1475-90 or information from the supplier or 
manufacturer of the material. If there is disagreement between ASTM 
Method D1475-90 test results and the supplier's or manufacturer's 
information, the test results will take precedence.
    (d) Calculate the organic HAP content of each coating. Calculate the 
organic HAP content, kg organic HAP per liter coating solids, of each 
coating used during the compliance period, using Equation 2 of this 
section, except that if the mass fraction of organic HAP in the coating 
equals zero, then the organic HAP content also equals zero and you are 
not required to use Equation 2 to calculate the organic HAP content.
[GRAPHIC] [TIFF OMITTED] TR23MY03.020

Where:

Hc = Organic HAP content of the coating, kg organic HAP per 
          liter coating solids.
Dc = Density of coating, kg coating per liter coating, 
          determined according to paragraph (c) of this section.
Wc = Mass fraction of organic HAP in the coating, kg organic 
          HAP per kg coating, determined according to paragraph (a) of 
          this section.
Vs = Volume fraction of coating solids, liter coating solids 
          per liter coating, determined according to paragraph (b) of 
          this section.

    (e) Compliance demonstration. The calculated organic HAP content for 
each coating used during the initial compliance period must be less than 
or equal to the applicable emission limit in Sec. 63.4890 and each 
thinner and cleaning material used during the initial compliance period 
must contain no organic HAP, determined according to paragraph (a) of 
this section. You must keep all records required by Sec. Sec. 63.4930 
and 63.4931. As part of the Notification of Compliance Status required 
in Sec. 63.4910(c) and the semiannual compliance reports required in 
Sec. 63.4920, you must identify each coating operation and group of 
coating operations for which you used the compliant material option. If 
there were no deviations from the emission limit, include a statement 
that each was in compliance with the emission limitations during the 
initial compliance period because it used no coatings for which the 
organic HAP content exceeded the applicable emission limit in Sec. 
63.4890, and it used no thinners or cleaning materials that contained 
organic HAP.



Sec. 63.4942  How do I demonstrate continuous compliance with the 
emission limitations?

    (a) Following the initial compliance period, you must complete a 
compliance demonstration according to the requirements in Sec. 
63.4941(e) for each

[[Page 826]]

subsequent compliance period. Each month following the initial 
compliance period described in Sec. 63.4940 is a compliance period.
    (b) If you choose to comply with the emission limitations by using 
the compliant material option, the use of any coating, thinner, or 
cleaning material that does not meet the criteria specified in paragraph 
(a) of this section is a deviation from the emission limitations that 
must be reported as specified in Sec. Sec. 63.4910(c)(6) and 
63.4920(a)(5).
    (c) As part of each semiannual compliance report required by Sec. 
63.4920, you must identify the coating operation or group of coating 
operations for which you used the compliant material option. If there 
were no deviations from the emission limits in Sec. 63.4890, submit an 
affirmative statement that the coating operation or group of coating 
operations was in compliance with the emission limitations during the 
reporting period because you used no coating for which the organic HAP 
content exceeded the applicable emission limit in Sec. 63.4890, and you 
used no thinner or cleaning material that contained organic HAP.
    (d) You must maintain records as specified in Sec. Sec. 63.4930 and 
63.4931.

 Compliance Requirements for the Emission Rate Without Add-On Controls 
                                 Option



Sec. 63.4950  By what date must I conduct the initial compliance
demonstration?

    You must complete the initial compliance demonstration for the 
initial compliance period according to the requirements of Sec. 
63.4951. The initial compliance period begins on the applicable 
compliance date specified in Sec. 63.4883 and ends on the last day of 
the first full month following the compliance date. The initial 
compliance demonstration includes the calculations showing that the 
organic HAP emission rate for the initial compliance period was equal to 
or less than the applicable emission limit in Sec. 63.4890.



Sec. 63.4951  How do I demonstrate initial compliance with the 
emission limitations?

    You may use the emission rate without add-on controls option for any 
individual coating operation, for any group of coating operations in the 
affected source, or for all the coating operations in the affected 
source to demonstrate compliance with an organic HAP emission limit. You 
must use either the compliant material option or the emission rate with 
add-on controls option for any coating operation in the affected source 
for which you do not use this option. To demonstrate initial compliance 
using the emission rate without add-on controls option, the coating 
operation or group of coating operations must comply with the applicable 
emission limit in Sec. 63.4890, but is not required to meet the 
operating limits or work practice standards in Sec. Sec. 63.4892 and 
63.4893, respectively. You must meet all the requirements of this 
section to demonstrate initial compliance with the applicable emission 
limit in Sec. 63.4890 for the coating operation or group of coating 
operations. When calculating the organic HAP emission rate according to 
this section, do not include any coatings, thinners, or cleaning 
materials used on coating operations for which you use the compliant 
material option or the emission rate with add-on controls option. You do 
not need to include organic HAP in coatings, thinners, or cleaning 
materials that have been reclaimed onsite and reused in the coating 
operation for which you use the emission rate without add-on controls 
option.
    (a) Determine the mass fraction of organic HAP for each material. 
You must determine the mass fraction of organic HAP for each coating, 
thinner, and cleaning material used during the compliance period 
according to the requirements in Sec. 63.4941(a).
    (b) Determine the volume fraction of coating solids for each 
coating. You must determine the volume fraction of coating solids for 
each coating used during the compliance period according to the 
requirements in Sec. 63.4941(b).
    (c) Determine the density of each material. You must determine the 
density of each coating, thinner, and cleaning material used during the 
compliance period according to the requirements in Sec. 63.4941(c) from 
test results using ASTM Method D1475-90, information from the supplier 
or manufacturer of

[[Page 827]]

the material, or reference sources providing density or specific gravity 
data for pure materials. If there is disagreement between ASTM Method 
D1475-90 test results and such other information sources, the test 
results will take precedence.
    (d) Determine the volume of each material used. You must determine 
the volume (liters) of each coating, thinner, and cleaning material used 
during the compliance period by measurement or usage records.
    (e) Calculate the mass of organic HAP emissions. The mass of organic 
HAP emissions is the combined mass of organic HAP contained in all 
coatings, thinners, and cleaning materials used during the compliance 
period minus the organic HAP in certain waste materials. Use Equation 1 
of this section to calculate the mass of organic HAP emissions:
[GRAPHIC] [TIFF OMITTED] TR23MY03.021

Where:

He = Total mass of organic HAP emissions during the 
          compliance period, kg.
A = Total mass of organic HAP in the coatings used during the compliance 
          period, kg, as calculated in Equation 1A of this section.
B = Total mass of organic HAP in the thinners used during the compliance 
          period, kg, as calculated in Equation 1B of this section.

          compliance period, kg, as calculated in Equation 1C of this 
          section.
Rw = Total mass of organic HAP in waste materials sent or 
          designated for shipment to a hazardous waste TSDF for 
          treatment or disposal during the compliance period, kg, 
          determined according to paragraph (e)(4) of this section. The 
          mass of any waste material reused during the same compliance 
          period may not be included in Rw. (You may assign a 
          value of zero to Rw if you do not wish to use this 
          allowance.)

    (1) Calculate the mass of organic HAP in the coatings used during 
the compliance period, using Equation 1A of this section:

          kg organic HAP per kg material.
p = Number of different cleaning materials used during the compliance 
          period.

    (4) If you choose to account for the mass of organic HAP contained 
in waste materials sent or designated for shipment to a hazardous waste 
TSDF in the calculation of the total mass of organic HAP emissions 
during the compliance period in Equation 1 of this section, then you 
must determine the total mass of organic HAP in waste

organic HAP in waste materials sent or designated for shipment to a 
hazardous waste TSDF for treatment or disposal during each compliance 
period only waste materials that are generated by coating operations for 
which you use Equation 1 of this section and that will be treated or 
disposed of by a facility regulated as a TSDF under 40 CFR part 262, 
264, 265, or 266. The TSDF may be either off-site or on-site. You may 
not include in the determination of the total mass of organic HAP in 
waste materials sent or designated for shipment to a hazardous waste 
TSDF for treatment or disposal during each compliance period only waste 
materials that are generated by coating operations the organic HAP 
contained in wastewater, nor the organic HAP contained in any waste 
material reused during the same compliance period.
    (ii) You must determine either the amount of the waste materials 
sent to a TSDF during the compliance period or the amount collected and 
stored during the compliance period and designated for future transport 
to a TSDF. Do not include in your determination of the total mass of 
organic HAP in waste materials sent or designated for shipment to a 
hazardous waste TSDF for treatment or disposal during each compliance 
period only waste materials that are generated by coating operations any 
waste materials sent to a TSDF during a compliance period if you have 
already included them in the amount collected and stored during that or 
a previous compliance period.
    (iii) Determine the total mass of organic HAP contained in the waste 
materials specified in paragraph (e)(4)(ii) of this section.
    (iv) You must document your methodology to determine the amount of 
waste materials and the total mass of organic HAP they contain, as 
required in Sec. 63.4930(h). To the extent that waste manifests include 
this information, they may be used as part of the documentation of the 
amount of waste materials and mass of organic HAP contained in them.
    (f) Calculate the total volume of coating solids used. Calculate the 
total volume of coating solids used, which is the combined volume of 
coating solids for all the coatings used during the compliance period,

          kg organic HAP per liter coating solids.
He = Total mass of organic HAP emissions from all materials 
          used during the compliance period, kg, as calculated by 
          Equation 1 of this section.
Vst = Total volume of coating solids used during the 
          compliance period, liters, as calculated by Equation 2 of this 
          section.

rate for the initial compliance period must be less than or equal to the 
applicable emission limit in Sec. 63.4890. You must keep all records as 
required by Sec. Sec. 63.4930 and 63.4931. As part of the Notification 
of Compliance Status required by Sec. 63.4910 and the semiannual 
compliance reports required in Sec. 63.4920, you must identify the 
coating operation or group of coating operations for which you used the 
emission rate without add-on controls option. If there were no 
deviations from the emission limit, include a statement that the coating 
operation or group of coating operations was in

[[Page 829]]

compliance with the emission limitations during the initial compliance 
period because the organic HAP emission rate was less than or equal to 
the applicable emission limit in Sec. 63.4890, determined according to 
this section.



Sec. 63.4952  How do I demonstrate continuous compliance with the
emission limitations?

    (a) Following the initial compliance period, you must complete a 
compliance demonstration according to the requirements in Sec. 
63.4951(h) for each subsequent compliance period. Each month following 
the initial compliance period described in Sec. 63.4950 is a compliance 
period.
    (b) If the organic HAP emission rate for any compliance period 
exceeded the applicable emission limit in Sec. 63.4890, this is a 
deviation from the emission limitations for that compliance period and 
must be reported as specified in Sec. Sec. 63.4910(c)(6) and 
63.4920(a)(6).
    (c) As part of each semiannual compliance report required by Sec. 
63.4920, you must identify the coating operation or group of coating 
operations for which you used the emission rate without add-on controls 
option. If there were no deviations from the emission limitations, you 
must submit an affirmative statement that the coating operation or group 
of coating operations was in compliance with the emission limitations 
during the reporting period because the organic HAP emission rate for 
each compliance period was less than or equal to the applicable emission 
limit in Sec. 63.4890.
    (d) You must maintain records as specified in Sec. Sec. 63.4930 and 
63.4931.

   Compliance Requirements for the Emission Rate With Add-On Controls 
                                 Option



Sec. 63.4960  By what date must I conduct performance tests and other
initial compliance demonstrations?

    (a) New and reconstructed affected sources. For a new or 
reconstructed affected source, you must meet the requirements of 
paragraphs (a)(1) through (4) of this section.
    (1) All emission capture systems, add-on control devices, and CPMS 
must be installed and operating no later than the applicable compliance 
date specified in Sec. 63.4883. Except for solvent recovery systems for 
which you conduct liquid-liquid material balances according to Sec. 
63.4961(j), you must conduct a performance test of each capture system 
and add-on control device according to Sec. Sec. 63.4963, 63.4964, and 
63.4965, and establish the operating limits required by Sec. 63.4892, 
no later than 180 days after the applicable compliance date specified in 
Sec. 63.4883. For a solvent recovery system for which you conduct 
liquid-liquid material balances according to Sec. 63.4961(j), you must

period between the compliance date and the

[[Page 830]]

performance test. You must begin complying with the operating limits for 
your affected source on the date you complete the performance tests 
specified in paragraph (a)(1) of this section. The requirements in this 
paragraph (a)(4) do not apply to solvent recovery systems for which you 
conduct liquid-liquid material balances.
    (b) Existing affected sources. For an existing affected source, you 
must meet the requirements of paragraphs (b)(1) through (3) of this 
section.
    (1) All emission capture systems, add-on control devices, and CPMS 
must be installed and operating no later than the applicable compliance 
date specified in Sec. 63.4883. Except for solvent recovery systems for 
which you conduct liquid-liquid material balances according to Sec. 
63.4961(j), you must conduct a performance test of each capture system 
and add-on control device according to the procedures in Sec. Sec. 
63.4963, 63.4964, and 63.4965, and establish the operating limits

the first full month following the compliance date. The initial 
compliance demonstration includes the results of emission capture system 
and add-on control device performance tests conducted according to 
Sec. Sec. 63.4963, 63.4964, and 63.4965; results of liquid-liquid 
material balances conducted according to Sec. 63.4961(j); calculations 
showing whether the organic HAP emission rate for the initial compliance 
period was equal to or less than the emission limit in Sec. 63.4890(c); 
the operating limits established during the performance tests and the 
results of the continuous parameter monitoring required by Sec. 
63.4967; and documentation of whether you developed and implemented the 
work practice plan required by Sec. 63.4893.



Sec. 63.4961  How do I demonstrate initial compliance?

    (a) When add-on controls are used. You may use the emission rate 
with add-on controls option for any coating operation, for any group of 
coating operations in the affected source, or for all of the coating 
operations in the affected source. You may include both controlled and 
uncontrolled coating operations in a group for which you use this 
option. You must use either the compliant material option or the 
emission rate without add-on controls option for any coating operation 
in the affected source for which you do not use the emission rate with 
add-on controls option. To demonstrate initial compliance, the coating 
operation or group of coating operations for which you use the emission 
rate with add-on controls option must meet the applicable emission limit 
in Sec. 63.4890, and each controlled coating operation must meet the 
operating limits and work practice standards required in Sec. Sec. 
63.4892 and 63.4893, respectively. You must meet all the requirements of 
this section to demonstrate initial compliance with the emission 
limitations. When calculating the organic HAP emission rate according to 
this section, do not include any coatings, thinners, or cleaning 
materials used on coating operations for which you use the compliant 
material option or the emission rate without add-on controls option.
    (b) Compliance with operating limits. Except as provided in Sec. 
63.4960(a)(4), you must establish and demonstrate continuous compliance 
during the initial compliance period with the operating limits required 
by Sec. 63.4892, using the procedures specified in Sec. Sec. 63.4966 
and 63.4967.
    (c) Compliance with work practice requirements. You must develop, 
implement, and document your implementation of the work practice plan 
required by Sec. 63.4893 during the initial compliance period, as 
specified in Sec. 63.4930.
    (d) Compliance with emission limits. You must follow the procedures 
in

[[Page 831]]

paragraphs (e) through (m) of this section to demonstrate compliance 
with the applicable emission limit in Sec. 63.4890.
    (e) Determine the mass fraction of organic HAP, density, volume 
used, and volume fraction of coating solids. Follow the procedures 
specified in Sec. 63.4951(a) through (d) to determine the mass fraction 
of organic HAP, density, and volume of each coating, thinner, and 
cleaning material used during each compliance period and the volume 
fraction of coating solids for each coating used during each compliance 
period.
    (f) Calculate the total mass of organic HAP emissions before add-on 
controls. Using Equation 1 of Sec. 63.4951, calculate the total mass of 
organic HAP emissions before add-on controls from all coatings, 
thinners, and cleaning materials used during the compliance period.
    (g) Calculate the organic HAP emission reduction for each controlled 
coating operation. Determine the mass of organic HAP emissions reduced 
for each controlled coating operation during each compliance period. The 
emission reduction determination quantifies the total organic HAP 
emissions that pass through the emission capture system and are 
destroyed or removed by the add-on control device. Use the procedures in 
paragraph (h) of this section to calculate the mass of organic HAP 
emission reduction for each controlled coating operation using an 
emission capture system and add-on control device other than a solvent 
recovery system for which you conduct liquid-liquid material balances. 
For each controlled coating operation using a solvent recovery system 
for which you conduct a liquid-liquid material balance, use the 
procedures in paragraph (j) of this section to calculate the organic HAP 
emission reduction.
    (h) Calculate the organic HAP emission reduction for controlled 
coating operations not using liquid-liquid material balance. For each 
controlled coating operation using an emission capture system and add-on 
control device other than a solvent recovery system for which you 
conduct liquid-liquid material balances, calculate the organic HAP 
emission reduction, using Equation 1 of this section. The calculation 
applies the emission capture system efficiency and add-on control device 
efficiency to the mass of organic HAP contained in the coatings, 
thinners, and cleaning materials that are used in the coating operation 
served by the emission capture system and add-on control device during 
the compliance period. For any period of time a deviation specified in 
Sec. 63.4962(c) or (d) occurs in the controlled coating operation, 
including a deviation during a period of startup, shutdown, or 
malfunction, you must assume zero efficiency for the emission capture 
system and add-on control device. Equation 1 of this section treats the 
materials used during such a deviation as if they were used on an 
uncontrolled coating operation for the time period of the deviation:

    (m) Compliance demonstration. To demonstrate initial compliance with 
the emission limit during the compliance period as calculated using

period must be less than or equal to the applicable emission limit in 
Sec. 63.4890. You must keep all records as required by Sec. Sec. 
63.4930 and 63.4931. As part of the Notification of Compliance Status 
required by Sec. 63.4910 and the semiannual compliance reports required 
in Sec. 63.4920, you must identify the coating operation or group of 
coating operations for

[[Page 836]]

which you used the emission rate with add-on controls option. If there 
were no deviations from the emission limit, include a statement that the 
coating operation or group of coating operations was in compliance with 
the emission limitations during the initial compliance period because 
the organic HAP emission rate was less than or equal to the applicable 
emission limit in Sec. 63.4890, and you achieved the operating limits 
required by Sec. 63.4892 and the work practice standards required by 
Sec. 63.4893.



Sec. 63.4962  How do I demonstrate continuous compliance with the
emission limitations?

    (a) Following the initial compliance period, you must complete a 
compliance demonstration according to the requirements in Sec. 
63.4961(m) for each subsequent compliance period. Each month following 
the initial compliance period described in Sec. 63.4960 is a compliance 
period.
    (b) If the organic HAP emission rate for any compliance period 
exceeded the applicable emission limit in Sec. 63.4890, this is a 
deviation from the emission limitation for that compliance period and 
must be reported as specified in Sec. Sec. 63.4910(c)(6) and 
63.4920(a)(7).
    (c) You must demonstrate continuous compliance with each operating 
limit required by Sec. 63.4892 that applies to you, as specified in 
Table 1 to this subpart.
    (1) If an operating parameter is out of the allowed range specified 
in Table 1 to this subpart, this is a deviation from the operating limit 
that must be reported as specified in Sec. Sec. 63.4910(c)(6) and 
63.4920(a)(7).
    (2) If an operating parameter deviates from the operating limit 
specified in Table 1 to this subpart, then you must assume that the 
emission capture system and add-on control device were achieving zero 
efficiency during the time period of the deviation. For the purposes of 
completing the compliance calculations specified in Sec. 63.4961, you 
must treat the materials used during a deviation on a controlled coating 
operation as if they were used on an uncontrolled coating operation for 
the time period of the deviation, as indicated in Equation 1 of Sec. 
63.4961.
    (d) You must meet the requirements for bypass lines in Sec. 
63.4967(b) for controlled coating operations for which you do not 
conduct liquid-liquid material balances. If any bypass line is opened 
and emissions are diverted to the atmosphere when the coating operation 
is running, this is a deviation that must be reported as specified in 
Sec. Sec. 63.4910(c)(6) and 63.4920(a)(7). For the purposes of 
completing the compliance calculations in Sec. 63.4961, you must treat 
the materials used during a deviation on a controlled coating operation 
as if they were used on an uncontrolled coating operation for the time 
period of the deviation, as indicated in Equation 1 of Sec. 63.4961.
    (e) You must demonstrate continuous compliance with the work 
practice standards in Sec. 63.4893. If you did not develop a work 
practice plan, or you did not implement the plan, or you did not keep 
the records required by Sec. 63.4930(k)(8), this is a deviation from 
the work practice standards that must be reported as specified in 
Sec. Sec. 63.4910(c)(6) and 63.4920(a)(7).
    (f) As part of each semiannual compliance report required in Sec. 
63.4920, you must identify the coating operation or group of coating 
operations for which you used the emission rate with add-on controls 
option. If there were no deviations from the emission limitations, 
submit an affirmative statement that you were in compliance with the 
emission limitations during the reporting period because the organic HAP 
emission rate for each compliance period was less than or equal to the 
applicable emission limit in Sec. 63.4890, and you achieved the 
operating limits required by Sec. 63.4892 and the work practice 
standards required by Sec. 63.4893 during each compliance period.
    (g)-(h) [Reserved]
    (i) You must maintain records as specified in Sec. Sec. 63.4930 and 
63.4931.

Sec. 63.4963  What are the general requirements for performance tests?

    (a) You must conduct each performance test required by Sec. 63.4960 
according to the requirements in Sec. 63.7(e)(1) and

[[Page 837]]

under the conditions in this section unless you obtain a waiver of the 
performance test according to the provisions in Sec. 63.7(h).
    (1) Representative coating operation operating conditions. You must 
conduct the performance test under representative operating conditions 
for the coating operation. Operations during periods of startup, 
shutdown, or malfunction, and during periods of nonoperation do not 
constitute representative conditions. You must record the process 
information that is necessary to document operating conditions during 
the test and explain why the conditions represent normal operation.
    (2) Representative emission capture system and add-on control device 
operating conditions. You must conduct the performance test when the 
emission capture system and add-on control device are operating at a 
representative flow rate, and the add-on control device is operating at 
a representative inlet concentration. You must record information that 
is necessary to document emission capture system and add-on control 
device operating conditions during the test and explain why the 
conditions represent normal operation.
    (b) You must conduct each performance test of an emission capture 
system according to the requirements in Sec. 63.4964. You must conduct 
each performance test of an add-on control device according to the 
requirements in Sec. 63.4965.
    (c) The performance test to determine add-on control device organic 
HAP destruction or removal efficiency must consist of three runs as 
specified in Sec. 63.7(e)(3) and each run must last at least 1 hour.



Sec. 63.4964  How do I determine the emission capture system
efficiency?

    You must use the procedures and test methods in this section to 
determine capture efficiency as part of the performance test required by 
Sec. 63.4960.
    (a) Assuming 100 percent capture efficiency. You may assume the 
capture system efficiency is 100 percent if both of the conditions in 
paragraphs (a)(1) and (2) of this section are met:
    (1) The capture system meets the criteria in Method 204 of appendix 
M to 40 CFR part 51 for a PTE and directs all the exhaust gases from the 
enclosure to an add-on control device.
    (2) All coatings, thinners, and cleaning materials used in the 
coating operation are applied within the capture system; coating solvent 
flash-off and coating, curing, and drying occurs within the capture 
system; and the removal of or evaporation of cleaning materials from the 
surfaces they are applied to occurs within the capture system. For 
example, this criterion is not met if parts enter the open shop 
environment when being moved between a spray booth and a curing oven.
    (b) Measuring capture efficiency. If the capture system does not 
meet both of the criteria in paragraphs (a)(1) and (2) of this section, 
then you must use one of the three protocols described in paragraphs 
(c), (d), and (e) of this section to measure capture efficiency. The 
capture efficiency measurements use TVH capture efficiency as a 
surrogate for organic HAP capture efficiency. For the protocols in 
paragraphs (c) and (d) of this section, the capture efficiency 
measurement must consist of three test runs. Each test run must be at 
least 3 hours duration or the length of a production run, whichever is 
longer, up to 8 hours. For the purposes of this test, a production run 
means the time required for a single part to go from the beginning to 
the end of production, which includes surface preparation activities and 
drying or curing time.
    (c) Liquid-to-uncaptured-gas protocol using a temporary total 
enclosure or building enclosure. The liquid-to-uncaptured-gas protocol 
compares the mass of liquid TVH in materials used in the coating 
operation to the mass of TVH emissions not captured by the emission 
capture system. Use a temporary total enclosure or a building enclosure 
and the procedures in paragraphs (c)(1) through (6) of this section to 
measure emission capture system efficiency using the liquid-to-
uncaptured-gas protocol.
    (1) Either use a building enclosure or construct an enclosure around 
the coating operation where coatings, thinners, and cleaning materials 
are applied, and all areas where emissions from these applied coatings 
and materials subsequently occur, such as flash-off, curing, and drying 
areas. The areas

[[Page 838]]

of the coating operation where capture devices collect emissions for 
routing to an add-on control device, such as the entrance and exit areas 
of an oven or spray booth, must also be inside the enclosure. The 
enclosure must meet the applicable definition of a temporary total 
enclosure or building enclosure in Method 204 of appendix M to 40 CFR 
part 51.
    (2) Use Method 204A or 204F of appendix M to 40 CFR part 51 to 
determine the mass fraction, kg TVH per kg material, of TVH liquid input 
from each coating, thinner, and cleaning material used in the coating 
operation during each capture efficiency test run. To make the 
determination, substitute TVH for each occurrence of the term VOC in the 
methods.
    (3) Use Equation 1 of this section to calculate the mass of TVH 
liquid input from all the coatings, thinners, and cleaning materials 
used in the coating operation during each capture efficiency test run:
[GRAPHIC] [TIFF OMITTED] TR23MY03.038

Where:

TVHused = Mass of liquid total volatile hydrocarbons in 
          materials used in the coating operation during the capture 
          efficiency test run, lb.
TVHi = Mass fraction of TVH in coating, thinner, or cleaning 
          material, i, that is used in the coating operation during the 
          capture efficiency test run, kg TVH per kg material.
Voli = Total volume of coating, thinner, or cleaning 
          material, i, used in the coating operation during the capture 
          efficiency test run, liters.
Di = Density of coating, thinner, or cleaning material, i, kg 
          material per liter material.
n = Number of different coatings, thinners, and cleaning materials used 
          in the coating operation during the capture efficiency test 
          run.

    (4) Use Method 204D or E of appendix M to 40 CFR part 51 to measure 
the total mass of TVH emissions that are not captured by the emission 
capture system; they are measured as they exit the temporary total 
enclosure or building enclosure during each capture efficiency test run. 
To make the measurement, substitute TVH for each occurrence of the term 
VOC in the methods.
    (i) Use Method 204D if the enclosure is a temporary total enclosure.
    (ii) Use Method 204E if the enclosure is a building enclosure. 
During the capture efficiency measurement, all organic compound emitting 
operations inside the building enclosure, other than the coating 
operation for which capture efficiency is being determined, must be shut 
down, but all fans and blowers must be operating normally.
    (5) For each capture efficiency test run, determine the percent 
capture efficiency of the emission capture system, using Equation 2 of 
this section:
[GRAPHIC] [TIFF OMITTED] TR23MY03.039

Where:

CE = Capture efficiency of the emission capture system vented to the 
          add-on control device, percent.
TVHused = Total mass of TVH liquid input used in the coating 
          operation during the capture efficiency test run, kg.
TVHuncaptured = Total mass of TVH that is not captured by the 
          emission capture system and that exits from the temporary 
          total enclosure or building enclosure during the capture 
          efficiency test run, kg.

    (6) Determine the capture efficiency of the emission capture system 
as the average of the capture efficiencies measured in the three test 
runs.
    (d) Gas-to-gas protocol using a temporary total enclosure or a 
building enclosure. The gas-to-gas protocol compares the mass of TVH 
emissions captured by the emission capture system to the mass of TVH 
emissions not captured. Use a temporary total enclosure or a building 
enclosure and the procedures

[[Page 839]]

in paragraphs (d)(1) through (5) of this section to measure emission 
capture system efficiency using the gas-to-gas protocol.
    (1) Either use a building enclosure or construct an enclosure around 
the coating operation where coatings, thinners, and cleaning materials 
are applied, and all areas where emissions from these applied coatings 
and materials subsequently occur, such as flash-off, curing, and drying 
areas. The areas of the coating operation where capture devices collect 
emissions generated by the coating operation for routing to an add-on 
control device, such as the entrance and exit areas of an oven or a 
spray booth, must also be inside the enclosure. The enclosure must meet 
the applicable definition of a temporary total enclosure or building 
enclosure in Method 204 of appendix M to 40 CFR part 51.
    (2) Use Method 204B or 204C of appendix M to 40 CFR part 51 to 
measure the total mass of TVH emissions captured by the emission capture 
system during each capture efficiency test run as measured at the inlet 
to the add-on control device. To make the measurement, substitute TVH 
for each occurrence of the term VOC in the methods.
    (i) The sampling points for the Method 204B or 204C measurement must 
be upstream from the add-on control device and must represent total 
emissions routed from the capture system and entering the add-on control 
device.
    (ii) If multiple emission streams from the capture system enter the 
add-on control device without a single common duct, then the emissions 
entering the add-on control device must be simultaneously measured in 
each duct and the total emissions entering the add-on control device 
must be determined.
    (3) Use Method 204D or 204E of appendix M to 40 CFR part 51 to 
measure the total mass of TVH emissions that are not captured by the 
emission capture system; they are measured as they exit the temporary 
total enclosure or building enclosure during each capture efficiency 
test run. To make the measurement, substitute TVH for each occurrence of 
the term VOC in the methods.
    (i) Use Method 204D if the enclosure is a temporary total enclosure.
    (ii) Use Method 204E if the enclosure is a building enclosure. 
During the capture efficiency measurement, all organic compound emitting 
operations inside the building enclosure, other than the coating 
operation for which capture efficiency is being determined, must be shut 
down, but all fans and blowers must be operating normally.
    (4) For each capture efficiency test run, determine the percent 
capture efficiency of the emission capture system, using Equation 3 of 
this section:
[GRAPHIC] [TIFF OMITTED] TR23MY03.040

Where:

CE = Capture efficiency of the emission capture system vented to the 
          add-on control device, percent.
TVHcaptured = Total mass of TVH captured by the emission 
          capture system as measured at the inlet to the add-on control 
          device during the emission capture efficiency test run, kg.
TVHuncaptured = Total mass of TVH that is not captured by the 
          emission capture system and that exits from the temporary 
          total enclosure or building enclosure during the capture 
          efficiency test run, kg.

    (5) Determine the capture efficiency of the emission capture system 
as the average of the capture efficiencies measured in the three test 
runs.
    (e) Alternative capture efficiency protocol. As an alternative to 
the procedures specified in paragraphs (c) and (d) of this section, you 
may determine capture efficiency using any other capture efficiency 
protocol and test methods that satisfy the criteria of either the DQO or 
LCL approach as described in appendix A to subpart KK of this part.

Sec. 63.4965  How do I determine the add-on control device emission
destruction or removal efficiency?

    You must use the procedures and test methods in this section to 
determine the add-on control device emission destruction or removal 
efficiency as part of the performance test required by Sec. 63.4960. 
You must conduct three test runs as specified in Sec. 63.7(e)(3), and 
each test run must last at least 1 hour.
    (a) For all types of add-on control devices, use the test methods 
specified in paragraphs (a)(1) through (5) of this section.
    (1) Use Method 1 or 1A of appendix A to 40 CFR part 60, as 
appropriate, to select sampling sites and velocity traverse points.
    (2) Use Method 2, 2A, 2C, 2D, 2F, or 2G of appendix A to 40 CFR part 
60, as appropriate, to measure gas volumetric flow rate.
    (3) Use Method 3, 3A, or 3B of appendix A to 40 CFR part 60, as 
appropriate, for gas analysis to determine dry molecular weight. You may 
also use as an alternative to Method 3B, the manual method for measuring 
the oxygen, carbon dioxide, and carbon monoxide content of exhaust gas 
in ANSI/ASME PTC 19.10-1981, ``Flue and Exhaust Gas Analyses [Part 10, 
Instruments and Apparatus]'' (incorporated by reference, see Sec. 
63.14).
    (4) Use Method 4 of appendix A to 40 CFR part 60 to determine stack 
gas moisture.
    (5) Methods for determining gas volumetric flow rate, dry molecular 
weight, and stack gas moisture must be performed, as applicable, during 
each test run.
    (b) Measure total gaseous organic mass emissions as carbon at the 
inlet and outlet of the add-on control device simultaneously, using 
either Method 25 or 25A of appendix A to 40 CFR part 60, as specified in 
paragraphs (b)(1) through (3) of this section. You must use the same 
method for both the inlet and outlet measurements.
    (1) Use Method 25 if the add-on control device is an oxidizer and 
you expect the total gaseous organic concentration as carbon to be more 
than 50 parts per million (ppm) at the control device outlet.
    (2) Use Method 25A if the add-on control device is an oxidizer and 
you expect the total gaseous organic concentration as carbon to be 50 
ppm or less at the control device outlet.
    (3) Use Method 25A if the add-on control device is not an oxidizer.
    (c) If two or more add-on control devices are used for the same 
emission stream, then you must measure emissions at the outlet of each 
device. For example, if one add-on control device is a concentrator with 
an outlet for the high-volume, dilute stream that has been treated by 
the concentrator, and a second add-on control device is an oxidizer with 
an outlet for the low-volume, concentrated stream that is treated with 
the oxidizer, you must measure emissions at the outlet of the oxidizer 
and the high volume dilute stream outlet of the concentrator.
    (d) For each test run, determine the total gaseous organic emissions 
mass flow rates for the inlet and the outlet of the add-on control 
device, using Equation 1 of this section. If there is more than one 
inlet or outlet to the add-on control device, you must calculate the 
total gaseous organic mass flow rate using Equation 1 of this section 
for each inlet and each outlet and then total all of the inlet emissions 
and total all of the outlet emissions.
[GRAPHIC] [TIFF OMITTED] TR23MY03.041

Where:

Mf = Total gaseous organic emissions mass flow rate, kg/per 
          hour (h).
Qsd = Volumetric flow rate of gases entering or exiting the 
          add-on control device, as determined by Method 2, 2A, 2C, 2D, 
          2F, or 2G, dry standard cubic meters/hour (dscm/h).
Cc = Concentration of organic compounds as carbon in the vent 
          gas, as determined by Method 25 or Method 25A, parts per 
          million by volume (ppmv), dry basis.
0.0416 = Conversion factor for molar volume, kg-moles per cubic meter 
          (mol/m\3\) (@ 293 Kelvin (K) and 760 millimeters of mercury 
          (mmHg)).

    (e) For each test run, determine the add-on control device organic 
emissions destruction or removal efficiency, using Equation 2 of this 
section:

[[Page 841]]

[GRAPHIC] [TIFF OMITTED] TR23MY03.042

Where:

DRE = Organic emissions destruction or removal efficiency of the add-on 
          control device, percent.
Mfi = Total gaseous organic emissions mass flow rate at the 
          inlet(s) to the add-on control device, using Equation 1 of 
          this section, kg/h.
Mfo = Total gaseous organic emissions mass flow rate at the 
          outlet(s) of the add-on control device, using Equation 1 of 
          this section, kg/h.

    (f) Determine the emission destruction or removal efficiency of the 
add-on control device as the average of the efficiencies determined in 
the three test runs and calculated in Equation 2 of this section.



Sec. 63.4966  How do I establish the emission capture system and
add-on control device operating limits during the performance test?

    During the performance test required by Sec. 63.4960 and described 
in Sec. Sec. 63.4963, 63.4964, and 63.4965, you must establish the 
operating limits required by Sec. 63.4892 according to this section, 
unless you have received approval for alternative monitoring and 
operating limits under Sec. 63.8(f) as specified in Sec. 63.4892.
    (a) Thermal oxidizers. If your add-on control device is a thermal 
oxidizer, establish the operating limits according to paragraphs (a)(1) 
and (2) of this section.
    (1) During the performance test, you must monitor and record the 
combustion temperature at least once every 15 minutes during each of the 
three test runs. You must monitor the temperature in the firebox of the 
thermal oxidizer or immediately downstream of the firebox before any 
substantial heat exchange occurs.
    (2) Use the data collected during the performance test to calculate 
and record the average combustion temperature maintained during the 
performance test. This average combustion temperature is the minimum 
operating limit for your thermal oxidizer.
    (b) Catalytic oxidizers. If your add-on control device is a 
catalytic oxidizer, establish the operating limits according to either 
paragraphs (b)(1) and (2) or paragraphs (b)(3) and (4) of this section.
    (1) During the performance test, you must monitor and record the 
temperature just before the catalyst bed and the temperature difference 
across the catalyst bed at least once every 15 minutes during each of 
the three test runs.
    (2) Use the data collected during the performance test to calculate 
and record the average temperature just before the catalyst bed and the 
average temperature difference across the catalyst bed maintained during 
the performance test. These are the minimum operating limits for your 
catalytic oxidizer.
    (3) As an alternative to monitoring the temperature difference 
across the catalyst bed, you may monitor the temperature at the inlet to 
the catalyst bed and implement a site-specific inspection and 
maintenance plan for your catalytic oxidizer as specified in paragraph 
(b)(4) of this section. During the performance test, you must monitor 
and record the temperature just before the catalyst bed at least once 
every 15 minutes during each of the three test runs. Use the data 
collected during the performance test to calculate and record the 
average temperature just before the catalyst bed during the performance 
test. This is the minimum operating limit for your catalytic oxidizer.
    (4) You must develop and implement an inspection and maintenance 
plan for your catalytic oxidizer(s) for which you elect to monitor 
according to paragraph (b)(3) of this section. The plan must address, at 
a minimum, the elements specified in paragraphs (b)(4)(i) through (iii) 
of this section.
    (i) Annual sampling and analysis of the catalyst activity (i.e., 
conversion efficiency) following the manufacturer's or catalyst 
supplier's recommended procedures.
    (ii) Monthly inspection of the oxidizer system, including the burner 
assembly and fuel supply lines for problems and, as necessary, adjust 
the equipment to assure proper air-to-fuel mixtures.
    (iii) Annual internal and monthly external visual inspection of the 
catalyst bed to check for channeling, abrasion,

[[Page 842]]

and settling. If problems are found, you must replace the catalyst bed 
or take corrective action consistent with the manufacturer's 
recommendations and conduct a new performance test to determine 
destruction efficiency according to Sec. 63.4965.
    (c) Carbon adsorbers. If your add-on control device is a carbon 
adsorber, establish the operating limits according to paragraphs (c)(1) 
and (2) of this section.
    (1) You must monitor and record the total regeneration desorbing gas 
(e.g., steam or nitrogen) mass flow for each regeneration cycle, and the 
carbon bed temperature after each carbon bed regeneration and cooling 
cycle, for the regeneration cycle either immediately preceding or 
immediately following the performance test.
    (2) The operating limits for your carbon adsorber are the minimum 
total desorbing gas mass flow recorded during the regeneration cycle and 
the maximum carbon bed temperature recorded after the cooling cycle.
    (d) Condensers. If your add-on control device is a condenser, 
establish the operating limits according to paragraphs (d)(1) and (2) of 
this section.
    (1) During the performance test, you must monitor and record the 
condenser outlet (product side) gas temperature at least once every 15 
minutes during each of the three test runs.
    (2) Use the data collected during the performance test to calculate 
and record the average condenser outlet (product side) gas temperature 
maintained during the performance test. This average condenser outlet 
gas temperature is the maximum operating limit for your condenser.
    (e) Emission capture system. For each capture device that is not 
part of a PTE that meets the criteria of Sec. 63.4964(a), establish an 
operating limit for either the gas volumetric flow rate or duct static 
pressure, as specified in paragraphs (e)(1) and (2) of this section. The 
operating limit for a PTE is specified in Table 1 to this subpart.
    (1) During the capture efficiency determination required by Sec. 
63.4960 and described in Sec. Sec. 63.4963 and 63.4964, you must 
monitor and record either the gas volumetric flow rate or the duct 
static pressure for each separate capture device in your emission 
capture system at least once every 15 minutes during each of the three 
test runs at a point in the duct between the capture device and the add-
on control device inlet.
    (2) Calculate and record the average gas volumetric flow rate or 
duct static pressure for the three test runs for each capture device. 
This average gas volumetric flow rate or duct static pressure is the 
minimum operating limit for that specific capture device.
    (f) Concentrators. If your add-on control device includes a 
concentrator, you must establish operating limits for the concentrator 
according to paragraphs (f)(1) through (4) of this section.
    (1) During the performance test, you must monitor and record the 
desorption concentrate stream gas temperature at least once every 15 
minutes during each of the three runs of the performance test.
    (2) Use the data collected during the performance test to calculate 
and record the average temperature. This is the minimum operating limit 
for the desorption concentrate gas stream temperature.
    (3) During the performance test, you must monitor and record the 
pressure drop of the dilute stream across the concentrator at least once 
every 15 minutes during each of the three runs of the performance test.
    (4) Use the data collected during the performance test to calculate 
and record the average pressure drop. This is the maximum operating 
limit for the dilute stream across the concentrator.
    (g) Bioreactors. If you are using a bioreactor, you must comply with 
the provisions for the use of an alternative monitoring method as set 
forth in 40 CFR 63.8(f).



Sec. 63.4967  What are the requirements for continuous parameter
monitoring system installation, operation, and maintenance?

    (a) General. You must install, operate, and maintain each CPMS 
specified in paragraphs (c), (e), and (f) of this section according to 
paragraphs (a)(1) through (6) of this section. You must install, 
operate, and maintain each CPMS specified in paragraphs (b) and (d) of 
this section according to paragraphs (a)(3) through (5) of this section.

[[Page 843]]

    (1) The CPMS must complete a minimum of one cycle of operation for 
each successive 15-minute period. You must have a minimum of four 
equally spaced successive cycles of CPMS operation in 1 hour.
    (2) You must determine the average of all recorded readings for each 
3-hour period of the emission capture system and add-on control device 
operation.
    (3) You must record the results of each inspection, calibration, and 
validation check of the CPMS.
    (4) You must maintain the CPMS at all times and have available 
necessary parts for routine repairs of the monitoring equipment.
    (5) You must operate the CPMS and collect emission capture system 
and add-on control device parameter data at all times that a controlled 
coating operation is operating, except during monitoring malfunctions, 
repairs to correct the monitor malfunctions, and required quality 
assurance or control activities (including, if applicable, calibration 
checks and required zero and span adjustments).
    (6) You must not use emission capture system or add-on control 
device parameter data recorded during monitoring malfunctions, repairs 
to correct the monitor malfunctions, out-of-control periods, or required 
quality assurance or control activities when calculating data averages. 
You must use all the data collected during all other periods in 
calculating the data averages for determining compliance with the 
emission capture system and add-on control device operating limits.
    (7) A monitoring malfunction is any sudden, infrequent, not 
reasonably preventable failure of the CPMS to provide valid data. 
Monitoring failures that are caused in part by poor maintenance or 
careless operation are not malfunctions. Any period for which the 
monitoring system is out-of-control and data are not available for 
required calculations is a deviation from the monitoring requirements.
    (b) Capture system bypass line. You must meet the requirements of 
paragraphs (b)(1) and (2) of this section for each emission capture 
system that contains bypass lines that could divert emissions away from 
the add-on control device to the atmosphere.
    (1) You must monitor or secure the valve or closure mechanism 
controlling the bypass line in a nondiverting position in such a way 
that the valve or closure mechanism cannot be opened without creating a 
record that the valve was opened. The method used to monitor or secure 
the valve or closure mechanism must meet one of the requirements 
specified in paragraphs (b)(1)(i) through (iv) of this section.
    (i) Flow control position indicator. Install, calibrate, maintain, 
and operate according to the manufacturer's specifications a flow 
control position indicator that takes a reading at least once every 15 
minutes and provides a record indicating whether the emissions are 
directed to the add-on control device or diverted from the add-on 
control device. The time of occurrence and flow control position must be 
recorded, as well as every time the flow direction is changed. The flow 
control position indicator must be installed at the entrance to any 
bypass line that could divert the emissions away from the add-on control 
device to the atmosphere.
    (ii) Car-seal or lock-and-key valve closures. Secure any bypass line 
valve in the closed position with a car-seal or a lock-and-key type 
configuration. You must visually inspect the seal or closure mechanism 
at least once every month to ensure that the valve is maintained in the 
closed position, and the emissions are not diverted away from the add-on 
control device to the atmosphere.
    (iii) Valve closure monitoring. Ensure that any bypass line valve is 
in the closed (nondiverting) position through monitoring of valve 
position at least once every 15 minutes. You must inspect the monitoring 
system at least once every month to verify that the monitor will 
indicate valve position.
    (iv) Automatic shutdown system. Use an automatic shutdown system in 
which the coating operation is stopped when flow is diverted by the 
bypass line away from the add-on control device to the atmosphere when 
the coating operation is running. You must inspect the automatic 
shutdown system at least once every month to verify that it will detect 
diversions of flow and shut down the coating operation.

Sec. 63.4981  What definitions apply to this subpart?

    Terms used in this subpart are defined in the CAA, in 40 CFR 63.2, 
and in this section as follows:
    Add-on control means an air pollution control device such as a 
thermal oxidizer or carbon adsorber that reduces pollution in an air 
stream by destruction or removal before discharge to the atmosphere.
    Adhesive means any chemical substance that is applied for the 
purpose of bonding two surfaces together.
    Capture device means a hood, enclosure, room, floor sweep, or other 
means of containing or collecting emissions and directing those 
emissions into an add-on air pollution control device.
    Capture efficiency or capture system efficiency means the portion 
(expressed as a percentage) of the pollutants from an emission source 
that is delivered to an add-on control device.
    Capture system means one or more capture devices intended to collect 
emissions generated by a coating operation in the use of coatings or 
cleaning materials, both at the point of application and at subsequent 
points where emissions from the coatings and cleaning materials occur, 
such as flashoff, drying, or curing. As used in this subpart, multiple 
capture devices that collect emissions generated by a coating operation 
are considered a single capture system.
    Cleaning material means a solvent used to remove contaminants and 
other materials, such as dirt, grease, oil, and dried or wet coating 
(e.g., depainting), from a substrate before or after coating application 
or from equipment associated with a coating operation, such as spray 
booths, spray guns, racks, tanks, and hangers. Thus, it includes any 
cleaning material used on substrates or equipment or both.
    Coating means a material applied to a substrate for decorative, 
protective, or functional purposes. Such materials include, but are not 
limited to, paints, sealants, caulks, inks, adhesives, and maskants. 
Decorative, protective, or functional materials that consist only of 
protective oils for metal, acids, bases, or any combination of these 
substances are not considered coatings for the purposes of this subpart.
    Coating operation means equipment used to apply cleaning materials 
to a substrate to prepare it for coating application or to remove dried 
or wet coating (surface preparation); to apply coating to a substrate 
(coating application) and to dry or cure the coating after application; 
and to clean coating operation equipment (equipment cleaning). A single 
coating operation may include any combination of these types of 
equipment, but always includes at least the point at which a coating or 
cleaning material is applied and all subsequent points in the affected 
source where organic HAP emissions from that coating or cleaning 
material occur. There may be multiple coating operations in an affected 
source. Coating application with hand-held nonrefillable aerosol 
containers, touchup markers, or marking pens is not a coating operation 
for the purposes of this subpart.
    Coating solids means the nonvolatile portion of the coating that 
makes up the dry film.
    Continuous parameter monitoring system (CPMS) means the total 
equipment that may be required to meet the data acquisition and 
availability requirements of this subpart, used to sample, condition (if 
applicable), analyze, and provide a record of coating operation, or 
capture system, or add-on control device parameters.
    Controlled coating operation means a coating operation from which 
some or all of the organic HAP emissions are routed through an emission 
capture system and add-on control device.
    Deviation means any instance in which an affected source subject to 
this subpart, or an owner or operator of such a source:
    (1) Fails to meet any requirement or obligation established by this 
subpart including, but not limited to, any emission limit, or operating 
limit, or work practice standard;
    (2) Fails to meet any term or condition that is adopted to implement 
an applicable requirement in this subpart and that is included in the 
operating

[[Page 847]]

permit for any affected source required to obtain such a permit; or
    (3) Fails to meet any emission limit, or operating limit, or work 
practice standard in this subpart during startup, shutdown, or 
malfunction, regardless of whether or not such failure is allowed by 
this subpart.
    Emission limitation means an emission limit, operating limit, or 
work practice standard.
    Enclosure means a structure that surrounds a source of emissions and 
captures and directs the emissions to an add-on control device.
    Exempt compound means a specific compound that is not considered a 
VOC due to negligible photochemical reactivity. The exempt compounds are 
listed in 40 CFR 51.100(s).
    Facility maintenance means the routine repair or renovation 
(including surface coating) of the tools, equipment, machinery, and 
structures that comprise the infrastructure of the affected facility and 
that are necessary for the facility to function in its intended 
capacity.
    Manufacturer's formulation data means data on a material (such as a 
coating) that are supplied by the material manufacturer based on 
knowledge of the ingredients used to manufacture that material, rather 
than based on testing of the material with the test methods specified in 
Sec. 63.4941(a)(1) through (3). Manufacturer's formulation data may 
include, but are not limited to, information on density, organic HAP 
content, volatile organic matter content, and coating solids content.

coating solids to the mass of a coating in which it is contained, 
expressed as kg of coating solids per kg of coating.
    Mass fraction of organic HAP means the ratio of the mass of organic 
HAP to the mass of a material in which it is contained, expressed as kg 
of organic HAP per kg of material.
    Month means a calendar month or a pre-specified period of 28 days to 
35 days to allow for flexibility in recordkeeping when data are based on 
a business accounting period.
    Organic HAP content means the mass of organic HAP per volume of 
coating solids for a coating, calculated using Equation 2 of Sec. 
63.4941. The organic HAP content is determined for the coating in the 
condition it is in when received from its manufacturer or supplier and 
does not account for any alteration after receipt.
    Permanent total enclosure (PTE) means a permanently installed 
enclosure that meets the criteria of Method 204 of appendix M, 40 CFR 
part 51, for a PTE and that directs all the exhaust gases from the 
enclosure to an add-on control device.
    Protective oil means an organic material that is applied to metal 
for the purpose of providing lubrication or protection from corrosion 
without forming a solid film. This definition of protective oil 
includes, but is not limited to, lubricating oils, evaporative oils 
(including those that evaporate completely), and extrusion oils.
    Research or laboratory facility means a facility whose primary 
purpose is for research and development of new processes and products, 
that is conducted under the close supervision of technically trained 
personnel, and is not engaged in the manufacture of final or 
intermediate products for commercial purposes, except in a de minimis 
manner.
    Responsible official means responsible official as defined in 40 CFR 
70.2.
    Startup, initial means the first time equipment is brought online in 
a facility.
    Surface preparation means use of a cleaning material on a portion of 
or all of a substrate. This includes use of a cleaning material to 
remove dried coating, which is sometimes called ``depainting'' or 
``paint stripping,'' for the purpose of preparing a substrate for 
coating application.
    Temporary total enclosure means an enclosure constructed for the 
purpose of measuring the capture efficiency of pollutants emitted from a 
given source as defined in Method 204 of appendix M, 40 CFR part 51.
    Thinner means an organic solvent that is added to a coating after 
the coating is received from the supplier.
    Total volatile hydrocarbon (TVH) means the total amount of 
nonaqueous volatile organic matter determined according to Methods 204 
and 204A

[[Page 848]]

through 204F of appendix M to 40 CFR part 51 and substituting the term 
TVH each place in the methods where the term VOC is used. The TVH 
includes both VOC and non-VOC.
    Uncontrolled coating operation means a coating operation from which 
none of the organic HAP emissions are routed through an emission capture 
system and add-on control device.
    Volatile organic compound (VOC) means any compound defined as VOC in 
40 CFR 51.100(s).
    Volume fraction of coating solids means the ratio of the volume of 
coating solids (also known as volume of nonvolatiles) to the volume of 
coating, expressed as liters of coating solids per liter of coating.
    Wastewater means water that is generated in a coating operation and 
is collected, stored, or treated prior to being discarded or discharged.

 Subpart SSSS_National Emission Standards for Hazardous Air Pollutants: 
                      Surface Coating of Metal Coil

    Source: 67 FR 39812, June 10, 2002, unless otherwise noted.

                        What This Subpart Covers



Sec. 63.5080  What is in this subpart?

    This subpart describes the actions you must take to reduce emissions 
of hazardous air pollutants (HAP) if you own or operate a facility that 
performs metal coil surface coating operations and is a major source of 
HAP. This subpart establishes emission standards

[[Page 854]]

and states what you must do to comply. Certain requirements apply to all 
who must comply with the subpart; others depend on the means you use to 
comply with an emission standard.



Sec. 63.5090  Does this subpart apply to me?

    (a) The provisions of this subpart apply to each facility that is a 
major source of HAP, as defined in Sec. 63.2, at which a coil coating 
line is operated, except as provided in paragraph (b) of this section.
    (b) This subpart does not apply to any coil coating line that meets 
the criteria of paragraph (b)(1) or (2) of this section.
    (1) A coil coating line that is part of research or laboratory 
equipment.
    (2) A coil coating line on which at least 85 percent of the metal 
coil coated, based on surface area, is less than 0.15 millimeter (0.006 
inch) thick, except as provided in paragraph (c) of this section.
    (c) If you operate a coating line subject to subpart JJJJ of this 
part that also meets the criteria in either paragraph (c)(1) or (2) of 
this section, and you choose to comply with the requirements of this 
subpart, then such compliance constitutes compliance with subpart JJJJ. 
The coating line for which you choose this option is, therefore, 
included in the affected source for this subpart as defined in Sec. 
63.5110 and shall not be included in the affected source for subpart 
JJJJ as defined in Sec. 63.3300.
    (1) The coating line is used to coat metal coil of thicknesses both 
less than and greater than or equal to 0.15 millimeter (0.006 inch) 
thick, regardless of the percentage of surface area of each thickness 
coated.
    (2) The coating line is used to coat only metal coil that is less 
than 0.15 millimeter (0.006 inch) thick and the coating line is 
controlled by a common control device that also receives organic HAP 
emissions from a coil coating line that is subject to the requirements 
of this subpart.
    (d) Each coil coating line that does not comply with the provisions 
of this subpart because it meets the criteria in paragraph (b)(2) of 
this section, that for any rolling 12-month period fails to meet the 
criteria in paragraph (b)(2) would from that point forward become 
subject to the provisions of this subpart. After becoming subject to the 
provisions of this subpart, the coil coating line would no longer be 
eligible to use the criteria of paragraph (b)(2) of this section, even 
if in subsequent 12-month periods at least 85 percent of the metal coil 
coated, based on surface area, is less than 0.15 millimeter (0.006 inch) 
thick.

the compliance date falls on any day other than the first day of a 
month, then the initial compliance period extends through that month 
plus the next 12 months.
    (e) For the purpose of demonstrating continuous compliance, a 
compliance period consists of 12 months. Each month after the end of the 
initial compliance period described in paragraph (d) of this section is 
the end of a compliance period consisting of that month and the 
preceding 11 months.

General Requirements for Compliance with the Emission Standards and for 
                    Monitoring and Performance Tests



Sec. 63.5140  What general requirements must I meet to comply with the
standards?

    (a) You must be in compliance with the standards in this subpart at 
all times, except during periods of start-up, shutdown, and malfunction 
of any capture system and control device used to comply with this 
subpart. If you are complying with the emission standards of this 
subpart without the use of a capture system and control device, you must 
be in compliance with the standards at all times, including periods of 
start-up, shutdown, and malfunction.
    (b) Table 2 of this subpart provides cross references to subpart A 
of this part, indicating the applicability of the General Provisions 
requirements to this subpart.



Sec. 63.5150  If I use a control device to comply with the emission
standards, what monitoring must I do?

 Table 1 to Sec. 63.5150--Control Device Monitoring Requirements Index
------------------------------------------------------------------------
If you operate a coil coating line
      and have the following:                  Then you must:
------------------------------------------------------------------------
1. Control device.................  Monitor control device operating
                                     parameters (Sec. 63.5150(a)(3)).
2. Capture system.................  Monitor capture system operating
                                     parameters (Sec. 63.5150(a)(4)).
3. Intermittently controllable      Monitor parameters related to
 work station.                       possible exhaust flow through any
                                     bypass to a control device (Sec.
                                     63.5150(a)(1)).
4. Continuous emission monitors...  Operate continuous emission monitors
                                     and perform a quarterly audit (Sec.
                                       63.5150(a)(2)).
------------------------------------------------------------------------

    (a) To demonstrate continuing compliance with the standards, you 
must monitor and inspect each capture system and each control device 
required to comply with Sec. 63.5120 following the date on which the 
initial performance test of the capture system and control device is 
completed. You must install and operate the monitoring equipment as 
specified in paragraphs (a)(1) through (4) of this section.
    (1) Bypass monitoring. If you operate coil coating lines with 
intermittently-controllable work stations, you must follow at least one 
of the procedures in paragraphs (a)(1)(i) through (iv) of this section 
for each curing oven associated with these work stations to monitor for 
potential bypass of the control device:
    (i) Flow control position indicator. Install, calibrate, maintain, 
and operate according to the manufacturer's specifications a flow 
control position indicator that provides a record indicating whether the 
exhaust stream from the curing oven is directed to the control device or 
is diverted from the control device. The time and flow control position 
must be recorded at least once per

[[Page 858]]

hour, as well as every time the flow direction is changed. The flow 
control position indicator must be installed at the entrance to any 
bypass line that could divert the exhaust stream away from the control 
device to the atmosphere.
    (ii) Car-seal or lock-and-key valve closures. Secure any bypass line 
valve in the closed position with a car-seal or a lock-and-key type 
configuration when the control device is in operation; a visual 
inspection of the seal or closure mechanism will be performed at least 
once every month to ensure that the valve or damper is maintained in the 
closed position, and the exhaust stream is not diverted through the 
bypass line.
    (iii) Valve closure continuous monitoring. Ensure that any bypass 
line valve or damper is in the closed position through continuous 
monitoring of valve position when the control device is in operation. 
The monitoring system must be inspected at least once every month to 
verify that the monitor will indicate valve position.
    (iv) Automatic shutdown system. Use an automatic shutdown system in 
which the coil coating line is stopped when flow is diverted away from 
the control device to any bypass line when the control device is in 
operation. The automatic shutdown system must be inspected at least once 
every month to verify that it will detect diversions of flow and shut 
down operations.
    (2) Continuous emission monitoring system (CEMS). If you are 
demonstrating continuous compliance with the standards in Sec. 
63.5120(a)(1) or (2) through continuous emission monitoring of a control 
device, you must install, calibrate, operate, and maintain continuous 
emission monitors to measure the total organic volatile matter 
concentration at both the control device inlet and outlet, and you must 
continuously monitor flow rate. If you are demonstrating continuous 
compliance with the outlet organic HAP concentration limit in Sec. 
63.5120(a)(3), you must install, calibrate, operate, and maintain a 
continuous emission monitor to measure the total organic volatile matter 
concentration at the control device outlet.
    (i) All CEMS must comply with performance specification 8 or 9 of 40 
CFR part 60, appendix B, as appropriate for the detection principle you 
choose. The requirements of 40 CFR part 60, procedure 1, appendix F must 
also be followed. In conducting the quarterly audits of the monitors as 
required by procedure 1, appendix F, you must use compounds 
representative of the gaseous emission stream being controlled.
    (ii) As specified in Sec. 63.8(c)(4)(ii), each CEMS and each flow 
rate monitor must complete a minimum of one cycle of operation 
(sampling, analyzing, and data recording) for each successive 15-minute 
period. Information which must be determined for recordkeeping purposes, 
as required by Sec. 63.5190(a)(1)(i) includes:
    (A) The hourly average of all recorded readings;
    (B) The daily average of all recorded readings for each operating 
day; and
    (C) The monthly average for each month during the semiannual 
reporting period.
    (3) Temperature monitoring of oxidizers. If you are complying with 
the requirements of the standards in Sec. 63.5120 through the use of an 
oxidizer and demonstrating continuous compliance through monitoring of 
an oxidizer operating parameter, you must comply with paragraphs 
(a)(3)(i) through (iii) of this section.
    (i) Install, calibrate, maintain, and operate temperature monitoring 
equipment according to manufacturer's specifications. The calibration of 
the chart recorder, data logger, or temperature indicator must be 
verified every 3 months; or the chart recorder, data logger, or 
temperature indicator must be replaced. You must replace the equipment 
either if you choose not to perform the calibration, or if the equipment 
cannot be calibrated properly. Each temperature monitoring device must 
be equipped with a continuous recorder. The device must have an accuracy 
of 1 percent of the temperature being monitored in 
degrees Celsius, or 1 [deg]Celsius, whichever is 
greater.
    (ii) For an oxidizer other than a catalytic oxidizer, to demonstrate 
continuous compliance with the operating limit established according to 
Sec. 63.5160(d)(3)(i), you must install the thermocouple or temperature 
sensor in

[[Page 859]]

the combustion chamber at a location in the combustion zone.
    (iii) For a catalytic oxidizer, if you are demonstrating continuous 
compliance with the operating limit established according to Sec. 
63.5160(d)(3)(ii)(A) and (B), then you must install the thermocouples or 
temperature sensors in the vent stream at the nearest feasible point to 
the inlet and outlet of the catalyst bed. Calculate the temperature 
difference across the catalyst. If you are demonstrating continuous 
compliance with the operating limit established according to Sec. 
63.5160(d)(3)(ii)(C) and (D), then you must install the thermocouple or 
temperature sensor in the vent stream at the nearest feasible point to 
the inlet of the catalyst bed.
    (4) Capture system monitoring. If you are complying with the 
requirements of the standards in Sec. 63.5120 through the use of a 
capture system and control device, you must develop a capture system 
monitoring plan containing the information specified in paragraphs 
(a)(4)(i) and (ii) of this section. You must monitor the capture system 
in accordance with paragraph (a)(4)(iii) of this section. You must make 
the monitoring plan available for inspection by the permitting authority 
upon request.
    (i) The monitoring plan must identify the operating parameter to be 
monitored to ensure that the capture efficiency measured during the 
initial compliance test is maintained, explain why this parameter is 
appropriate for demonstrating ongoing compliance, and identify the 
specific monitoring procedures.
    (ii) The plan also must specify operating limits at the capture 
system operating parameter value, or range of values, that demonstrates 
compliance with the standards in Sec. 63.5120. The operating limits 
must represent the conditions indicative of proper operation and 
maintenance of the capture system.
    (iii) You must conduct monitoring in accordance with the plan.
    (b) Any deviation from the required operating parameters which are 
monitored in accordance with paragraphs (a)(3) and (4) of this section, 
unless otherwise excused, will be considered a deviation from the 
operating limit.

                                          Sec. 63.5160(e).
------------------------------------------------------------------------

    (a) If you use a control device to comply with the requirements of 
Sec. 63.5120, you are not required to conduct a performance test to 
demonstrate compliance if one or more of the criteria in paragraphs 
(a)(1) through (3) of this section are met:

for determining total organic volatile matter concentration, and capture 
efficiency has been determined in accordance with the requirements of 
this subpart; and the continuous emission monitors are used to 
demonstrate continuous compliance in accordance with Sec. 
63.5150(a)(2); or
    (2) You have received a waiver of performance testing under Sec. 
63.7(h); or
    (3) The control device is a solvent recovery system and you choose 
to comply by means of a monthly liquid-liquid material balance.
    (b) Organic HAP content. You must determine the organic HAP weight

[[Page 860]]

fraction of each coating material applied by following one of the 
procedures in paragraphs (b)(1) through (4) of this section:
    (1) Method 311. You may test the material in accordance with Method 
311 of appendix A of this part. The Method 311 determination may be 
performed by the manufacturer of the material and the results provided 
to you. The organic HAP content must be calculated according to the 
criteria and procedures in paragraphs (b)(1)(i) through (iii) of this 
section.
    (i) Count only those organic HAP that are measured to be present at 
greater than or equal to 0.1 weight percent for Occupational Safety and 
Health Administration (OSHA)-defined carcinogens as specified in 29 CFR 
1910.1200(d)(4) and greater than or equal to 1.0 weight percent for 
other organic HAP compounds.
    (ii) Express the weight fraction of each organic HAP you count 
according to paragraph (b)(1)(i) of this section as a value truncated to 
four places after the decimal point (for example, 0.3791).
    (iii) Calculate the total weight fraction of organic HAP in the 
tested material by summing the counted individual organic HAP weight 
fractions and truncating the result to three places after the decimal 
point (for example, 0.763).
    (2) Method 24. For coatings, you may determine the total volatile 
matter content as weight fraction of nonaqueous volatile matter and use 
it as a substitute for organic HAP, using Method 24 of 40 CFR part 60, 
appendix A. The Method 24 determination may be performed by the 
manufacturer of the coating and the results provided to you.
    (3) Alternative method. You may use an alternative test method for 
determining the organic HAP weight fraction once the Administrator has 
approved it. You must follow the procedure in Sec. 63.7(f) to submit an 
alternative test method for approval.
    (4) Formulation data. You may use formulation data provided that the 
information represents each organic HAP present at a level equal to or 
greater than 0.1 percent for OSHA-defined carcinogens as specified in 29 
CFR 1910.1200(d)(4) and equal to or greater than 1.0 percent for other 
organic HAP compounds in any raw material used, weighted by the mass 
fraction of each raw material used in the material. Formulation data may 
be provided to you by the manufacturer of the coating material. In the 
event of any inconsistency between test data obtained with the test 
methods specified in paragraphs (b)(1) through (3) of this section and 
formulation data, the test data will govern.
    (c) Solids content. You must determine the solids content of each 
coating material applied. You may determine the volume solids content 
using ASTM D2697-86 (Reapproved 1998) or ASTM D6093-97 (incorporated by 
reference, see Sec. 63.14), or an EPA approved alternative method. The 
ASTM D2697-86 (Reapproved 1998) or ASTM D6093-97 determination may be 
performed by the manufacturer of the material and the results provided 
to you. Alternatively, you may rely on formulation data provided by 
material providers to determine the volume solids.
    (d) Control device destruction or removal efficiency. If you are 
using an add-on control device, such as an oxidizer, to comply with the 
standard in Sec. 63.5120, you must conduct a performance test to 
establish the destruction or removal efficiency of the control device or 
the outlet HAP concentration achieved by the oxidizer, according to the 
methods and procedures in paragraphs (d)(1) and (2) of this section. 
During the performance test, you must establish the operating limits 
required by Sec. 63.5121 according to paragraph (d)(3) of this section.
    (1) An initial performance test to establish the destruction or 
removal efficiency of the control device must be conducted such that 
control device inlet and outlet testing is conducted simultaneously. To 
establish the outlet organic HAP concentration achieved by the oxidizer, 
only oxidizer outlet testing must be conducted. The data must be reduced 
in accordance with the test methods and procedures in paragraphs 
(d)(1)(i) through (ix).
    (i) Method 1 or 1A of 40 CFR part 60, appendix A, is used for sample 
and velocity traverses to determine sampling locations.

[[Page 861]]

    (ii) Method 2, 2A, 2C, 2D, 2F, or 2G of 40 CFR part 60, appendix A, 
is used to determine gas volumetric flow rate.
    (iii) Method 3, 3A, or 3B of 40 CFR part 60, appendix A, used for 
gas analysis to determine dry molecular weight. You may also use as an 
alternative to Method 3B, the manual method for measuring the oxygen, 
carbon dioxide, and carbon monoxide content of exhaust gas, ANSI/ASME 
PTC 19.10-1981, ``Flue and Exhaust Gas Analyses'' (incorporated by 
reference, see Sec. 63.14).
    (iv) Method 4 of 40 CFR part 60, appendix A, is used to determine 
stack gas moisture.
    (v) Methods for determining gas volumetric flow rate, dry molecular 
weight, and stack gas moisture must be performed, as applicable, during 
each test run, as specified in paragraph (d)(1)(vii) of this section.
    (vi) Method 25 or 25A of 40 CFR part 60, appendix A, is used to 
determine total gaseous non-methane organic matter concentration. Use 
the same test method for both the inlet and outlet measurements, which 
must be conducted simultaneously. You must submit notification of the 
intended test method to the Administrator for approval along with 
notification of the performance test required under Sec. 63.7 (b). You 
must use Method 25A if any of the conditions described in paragraphs 
(d)(1)(vi)(A) through (D) of this section apply to the control device.
    (A) The control device is not an oxidizer.
    (B) The control device is an oxidizer, but an exhaust gas volatile 
organic matter concentration of 50 ppmv or less is required to comply 
with the standards in Sec. 63.5120; or
    (C) The control device is an oxidizer, but the volatile organic 
matter concentration at the inlet to the control system and the required 
level of control are such that they result in exhaust gas volatile 
organic matter concentrations of 50 ppmv or less; or
    (D) The control device is an oxidizer, but because of the high 
efficiency of the control device, the anticipated volatile organic 
matter concentration at the control device exhaust is 50 ppmv or less, 
regardless of inlet concentration.
    (vii) Each performance test must consist of three separate runs, 
except as provided by Sec. 63.7(e)(3); each run must be conducted for 
at least 1 hour under the conditions that exist when the affected source 
is operating under normal operating conditions. For the purpose of 
determining volatile organic matter concentrations and mass flow rates, 
the average of the results of all runs will apply. If you are 
demonstrating initial compliance with the outlet organic HAP 
concentration limit in Sec. 63.5120(a)(3), only the average outlet 
volatile organic matter concentration must be determined.
    (viii) If you are determining the control device destruction or 
removal efficiency, for each run, determine the volatile organic matter 
mass flow rates using Equation 1 of this section:
[GRAPHIC] [TIFF OMITTED] TR10JN02.000

Where:

Mf = total organic volatile matter mass flow rate, kg/per 
          hour (h).
Cc = concentration of organic compounds as carbon in the vent 
          gas, as determined by Method 25 or Method 25A, ppmv, dry 
          basis.
Qsd = volumetric flow rate of gases entering or exiting the 
          control device, as determined by Method 2, 2A, 2C, 2D, 2F, or 
          2G, dry standard cubic meters (dscm)/h.
0.0416=conversion factor for molar volume, kg-moles per cubic meter 
          (mol/m\3\) (@ 293 Kelvin (K) and 760 millimeters of mercury 
          (mmHg)).

    (ix) For each run, determine the control device destruction or 
removal efficiency, DRE, using Equation 2 of this section:
[GRAPHIC] [TIFF OMITTED] TR10JN02.001

Where:

DRE=organic emissions destruction or removal efficiency of the add-on 
          control device, percent.
Mfi = organic volatile matter mass flow rate at the inlet to 
          the control device, kg/h.
Mfo = organic volatile matter mass flow rate at the outlet of 
          the control device, kg/h.

    (x) The control device destruction or removal efficiency is 
determined as the average of the efficiencies determined in the three 
test runs and calculated in Equation 2 of this section.

[[Page 862]]

    (2) You must record such process information as may be necessary to 
determine the conditions in existence at the time of the performance 
test. Operations during periods of start-up, shutdown, and malfunction 
will not constitute representative conditions for the purpose of a 
performance test.
    (3) Operating limits. If you are using a capture system and add-on 
control device other than a solvent recovery system for which you 
conduct a liquid-liquid material balance to comply with the requirements 
in Sec. 63.5120, you must establish the applicable operating limits 
required by Sec. 63.5121. These operating limits apply to each capture 
system and to each add-on emission control device that is not monitored 
by CEMS, and you must establish the operating limits during the 
performance test required by paragraph (d) of this section according to 
the requirements in paragraphs (d)(3)(i) through (iii) of this section.
    (i) Thermal oxidizer. If your add-on control device is a thermal 
oxidizer, establish the operating limits according to paragraphs 
(d)(3)(i)(A) and (B) of this section.
    (A) During the performance test, you must monitor and record the 
combustion temperature at least once every 15 minutes during each of the 
three test runs. You must monitor the temperature in the firebox of the 
thermal oxidizer or immediately downstream of the firebox before any 
substantial heat exchange occurs.
    (B) Use the data collected during the performance test to calculate 
and record the average combustion temperature maintained during the 
performance test. This average combustion temperature is the minimum 
operating limit for your thermal oxidizer.
    (ii) Catalytic oxidizer. If your add-on control device is a 
catalytic oxidizer, establish the operating limits according to either 
paragraphs (d)(3)(ii)(A) and (B) or paragraphs (d)(3)(ii)(C) and (D) of 
this section.
    (A) During the performance test, you must monitor and record the 
temperature just before the catalyst bed and the temperature difference 
across the catalyst bed at least once every 15 minutes during each of 
the three test runs.
    (B) Use the data collected during the performance test to calculate 
and record the average temperature just before the catalyst bed and the 
average temperature difference across the catalyst bed maintained during 
the performance test. These are the minimum operating limits for your 
catalytic oxidizer.
    (C) As an alternative to monitoring the temperature difference 
across the catalyst bed, you may monitor the temperature at the inlet to 
the catalyst bed and implement a site-specific inspection and 
maintenance plan for your catalytic oxidizer as specified in paragraph 
(d)(3)(ii)(D) of this section. During the performance test, you must 
monitor and record the temperature just before the catalyst bed at least 
once every 15 minutes during each of the three test runs. Use the data 
collected during the performance test to calculate and record the 
average temperature just before the catalyst bed during the performance 
test. This is the minimum operating limit for your catalytic oxidizer.
    (D) You must develop and implement an inspection and maintenance 
plan for your catalytic oxidizer(s) for which you elect to monitor 
according to paragraph (d)(3)(ii)(C) of this section. The plan must 
address, at a minimum, the elements specified in paragraphs 
(d)(3)(ii)(D)(1 (3) of this section.
    (1) Annual sampling and analysis of the catalyst activity (i.e., 
conversion efficiency) following the manufacturer's or catalyst 
supplier's recommended procedures.
    (2) Monthly inspection of the oxidizer system including the burner 
assembly and fuel supply lines for problems and,
    (3) Annual internal and monthly external visual inspection of the 
catalyst bed to check for channeling, abrasion, and settling. If 
problems are found, you must take corrective action consistent with the 
manufacturer's recommendations and conduct a new performance test to 
determine destruction efficiency according to Sec. 63.5160.
    (iii) Other types of control devices. If you use a control device 
other than an oxidizer or a solvent recovery system for which you choose 
to comply by

[[Page 863]]

means of a monthly liquid-liquid material balance, or wish to monitor an 
alternative parameter and comply with a different operating limit, you 
must apply to the Administrator for approval of alternative monitoring 
under Sec. 63.8(f).
    (e) Capture efficiency. If you are required to determine capture 
efficiency to meet the requirements of Sec. 63.5170(e)(2), (f)(1) 
through (2), (h)(2) through (4), or (i)(2) through (3), you must 
determine capture efficiency using the procedures in paragraph (e)(1), 
(2), or (3) of this section, as applicable.
    (1) For an enclosure that meets the criteria for a PTE, you may 
assume it achieves 100 percent capture efficiency. You must confirm that 
your capture system is a PTE by demonstrating that it meets the 
requirements of section 6 of EPA Method 204 of 40 CFR part 51, appendix 
M (or an EPA approved alternative method), and that all exhaust gases 
from the enclosure are delivered to a control device.
    (2) You may determine capture efficiency, CE, according to the 
protocols for testing with temporary total enclosures that are specified 
in Method 204A through F of 40 CFR part 51, appendix M. You may exclude 
never-controlled work stations from such capture efficiency 
determinations.
    (3) As an alternative to the procedures specified in paragraphs 
(e)(1) and (2) of this section, if you are required to conduct a capture 
efficiency test, you may use any capture efficiency protocol and test 
methods that satisfy the criteria of either the Data Quality Objective 
or the Lower Confidence Limit approach as described in appendix A to 
subpart KK of this part. You may exclude never-controlled work stations 
from such capture efficiency determinations.

                   Requirements for Showing Compliance



Sec. 63.5170  How do I demonstrate compliance with the standards?

    You must include all coating materials (as defined in Sec. 63.5110) 
used in the affected source when determining compliance with the 
applicable emission limit in Sec. 63.5120. To make this determination, 
you must use at least one of the four compliance options listed in Table 
1 of this section. You may apply any of the compliance options to an 
individual coil coating line, or to multiple lines as a group, or to the 
entire affected source. You may use different compliance options for 
different coil coating lines, or at different times on the same line. 
However, you may not use different compliance options at the same time 
on the same coil coating line. If you switch between compliance options 
for any coil coating line or group of lines, you must document this 
switch as required by Sec. 63.5190(a), and you must report it in the 
next semiannual compliance report required in Sec. 63.5180.

    (a) As-purchased compliant coatings. If you elect to use coatings 
that individually meet the organic HAP emission limit in Sec. 
63.5120(a)(2) as-purchased, to which you will not add HAP during 
distribution or application, you must demonstrate that each coating 
material applied during the 12-month compliance period contains no more 
than 0.046 kg HAP per liter of solids on an as-purchased basis.
    (1) Determine the organic HAP content for each coating material in 
accordance with Sec. 63.5160(b) and the volume solids content in 
accordance with Sec. 63.5160(c).
    (2) Combine these results using Equation 1 of this section and 
compare the result to the organic HAP emission limit in Sec. 
63.5120(a)(2) to demonstrate that each coating material contains no more 
organic HAP than the limit.

          as a weight-fraction, kg/kg.
Di = density of coating material, i, kg/l.

each coating material applied during the 12-month compliance period 
contains no more than 0.046 kg of organic HAP per liter of solids 
applied in accordance with (b)(1) of this section, or demonstrate that 
the average of all coating materials applied during the 12-month 
compliance period contain no more than 0.046 kg of organic HAP per liter 
of solids applied in accordance with paragraph (b)(2) of this section.
    (1) To demonstrate that the average organic HAP content on the basis 
of solids applied for each coating material applied, HSi yr, 
is less than 0.046 kg HAP per liter solids applied for the 12-month 
compliance period, use Equation 2 of this section:
[GRAPHIC] [TIFF OMITTED] TR10JN02.003

Where:

Hsi yr = average for the 12-month compliance period, as-
          applied, organic HAP to solids ratio of material, i, kg 
          organic HAP/liter solids applied.
Vi = volume of coating material, i, l.
Di = density of coating material, i, kg/l.
Cahi = monthly average, as-applied, organic HAP content of 
          solids-containing coating material, i, expressed as a weight 
          fraction, kilogram (kg)/kg.

          non-solids-containing coating materials applied in a month.

    (2) To demonstrte that the average organic HAP content on the basis 
of solids applied, HS yr, of all coating materials applied is 
less than 0.046 kg HAP per liter solids applied for the 12-month 
compliance period, use Equation 3 of this section:

[[Page 865]]

[GRAPHIC] [TIFF OMITTED] TR10JN02.004

Where:

          non-solids-containing coating materials applied in a month.
y = identifier for months.

    (c) Capture and control to reduce emissions to no more than the 
allowable limit. If you use one or more capture systems and one or more 
control devices and demonstrate an average overall organic HAP control 
efficiency of at least 98 percent for each month to comply with Sec. 
63.5120(a)(1); or operate a capture system and oxidizer so that the 
capture efficiency is 100 percent and the oxidizer outlet HAP 
concentration is no greater than 20 ppmv on a dry basis to comply with 
Sec. 63.5120(a)(3), you must follow one of the procedures in paragraphs 
(c)(1) through (4) of this section. Alternatively, you may demonstrate 
compliance for an individual coil coating line by operating its capture 
system and control device and continuous parameter monitoring system 
according to the procedures in paragraph (i) of this section.
    (1) If the affected source uses one compliance procedure to limit 
organic HAP emissions to the level specified in Sec. 63.5120(a)(1) or 
(2) and has only always-controlled work stations, then you must 
demonstrate compliance with the provisions of paragraph (e) of this 
section when emissions from the affected source are controlled by one or 
more solvent recovery devices.
    (2) If the affected source uses one compliance procedure to limit 
organic HAP emissions to the level specified in Sec. 63.5120(a)(1) or 
(2) and has only always-controlled work stations, then you must 
demonstrate compliance with the provisions of paragraph (f) of this 
section when emissions are controlled by one or more oxidizers.
    (3) If the affected source operates both solvent recovery and 
oxidizer control devices, one or more never-controlled work stations, or 
one or more intermittently-controllable work stations, or uses more than 
one compliance procedure, then you must demonstrate compliance with the 
provisions of paragraph (g) of this section.
    (4) The method of limiting organic HAP emissions to the level 
specified in Sec. 63.5120(a)(3) is the installation and operation of a 
PTE around each work station and associated curing oven in the coating 
line and the ventilation of all organic HAP emissions from each PTE to 
an oxidizer with an outlet organic HAP concentration of no greater than 
20 ppmv on a dry basis. An enclosure that meets the requirements in 
Sec. 63.5160(e)(1) is considered a PTE. Initial compliance of the

 Subpart TTTT_National Emission Standards for Hazardous Air Pollutants 
                    for Leather Finishing Operations

    Source: 67 FR 9162, Feb. 27, 2002, unless otherwise noted.

                        What This Subpart Covers



Sec. 63.5280  What is the purpose of this subpart?

    This subpart establishes national emission standards for hazardous 
air pollutants (NESHAP) for leather finishing operations. These 
standards limit HAP emissions from specified leather finishing 
operations. This subpart also establishes requirements to demonstrate 
initial and continuous compliance with the emission standards.



Sec. 63.5285  Am I subject to this subpart?

    (a) You are subject to this subpart if you own or operate a leather 
finishing operation that is a major source of hazardous air pollutants 
(HAP) emissions or that is located at, or is part of, a major source of 
HAP emissions. A leather finishing operation is defined in Sec. 
63.5460. In general, a leather finishing operation is a single process 
or group of processes used to adjust and improve the physical and 
aesthetic characteristics of the leather surface through multistage 
application of a coating comprised of dyes, pigments, film-forming 
materials, and performance modifiers dissolved or suspended in liquid 
carriers.
    (b) You are a major source of HAP emissions if you own or operate a 
plant site that emits or has the potential to emit any single HAP at a 
rate of 10 tons (9.07 megagrams) or more per year or any combination of 
HAP at a rate of 25 tons (22.68 megagrams) or more per year.
    (c) You are not subject to this subpart if your source finishes

                         Compliance Requirements



Sec. 63.5320  How does my affected major source comply with the HAP
emission standards?

    (a) All affected sources must be in compliance with the requirements 
of this subpart at all times, including periods of startup, shutdown, 
and malfunction.
    (b) You must always operate and maintain your affected source, 
including air pollution control and monitoring equipment, according to 
the provisions in Sec. 63.6(e)(1)(i).
    (c) You must perform all of the items listed in paragraphs (c)(1) 
through (10) of this section:

[[Page 881]]

    (1) Submit the necessary notifications in accordance with Sec. 
63.5415.
    (2) Develop and implement a plan for demonstrating compliance in 
accordance with Sec. 63.5325.
    (3) Submit the necessary reports in accordance with Sec. 63.5420.
    (4) Keep a finish inventory log, as specified at Sec. 63.5335(b), 
to record monthly the pounds of each type of finish applied for each 
leather product process operation and the mass fraction of HAP in each 
applied finish. You may be required to start recordkeeping prior to the 
compliance dates specified at Sec. 63.5295.
    (5) Keep an inventory log, as specified at Sec. 63.5430(f), to 
record monthly the surface area of leather processed in 1,000's of 
square feet for each product process operation. You may be required to 
start recordkeeping prior to the compliance dates specified at Sec. 
63.5295.
    (6) Determine the actual HAP loss from your affected source in 
accordance with Sec. 63.5335.
    (7) Determine the allowable HAP loss for your affected source in 
accordance with Sec. 63.5340.
    (8) Determine the compliance ratio for your affected source each 
month as specified at Sec. 63.5330. The compliance ratio compares your 
actual HAP loss to your allowable HAP loss for the previous 12 months.
    (9) Maintain the compliance ratio for your affected source at or 
below 1.00 in accordance with Sec. 63.5330.
    (10) Maintain all the necessary records you have used to demonstrate 
compliance with this subpart in accordance with Sec. 63.5430.



Sec. 63.5325  What is a plan for demonstrating compliance and when
must I have one in place?

    (a) You must develop and implement a written plan for demonstrating 
compliance that provides the detailed procedures you will follow to 
monitor and record data necessary for demonstrating compliance with this 
subpart. Procedures followed for quantifying HAP loss from the source 
and amount of leather processed vary from source to source because of 
site-specific factors such as equipment design characteristics and 
operating conditions. Typical procedures include one or more accurate 
measurement methods such as weigh scales and volumetric displacement. 
Because the industry does not have a uniform set of procedures, you must 
develop and implement your own site-specific plan for demonstrating 
compliance not later than the compliance date for your source. You must 
also incorporate the plan for demonstrating compliance by reference in 
the source's title V permit. The plan for demonstrating compliance must 
include the items listed in paragraphs (a)(1) through (7) of this 
section:
    (1) The name and address of the owner or operator.
    (2) The physical address of the leather finishing operation.
    (3) Provide a detailed description of all methods of measurement 
your source will use to determine your finish usage, HAP content of each 
finish, quantity of leather processed, and leather product process 
operation type.
    (4) Specify when each measurement will be made.
    (5) Provide examples of each calculation you will use to determine 
your compliance status. Include examples of how you will convert data 
measured with one parameter to other terms for use in compliance 
determination.
    (6) Provide example logs of how data will be recorded.
    (7) Provide a quality assurance/quality control plan to ensure that 
the data continue to meet compliance demonstration needs.
    (b) You may be required to revise your plan for demonstrating 
compliance. We may require reasonable revisions if the procedures lack 
detail, are inconsistent, or do not accurately determine finish usage, 
HAP content of each finish, quantity of leather processed, or leather 
product process operation type.



Sec. 63.5330  How do I determine the compliance ratio?

    (a) When your source has processed leather for 12 months, you must 
determine the compliance ratio for your affected source by the fifteenth 
of each month for the previous 12 months.
    (b) You must determine the compliance ratio using Equation 1 of this 
section as follows:

[[Page 882]]

[GRAPHIC] [TIFF OMITTED] TR27FE02.003

Where:

Actual HAP Loss = Pounds of actual HAP loss for the previous 12 months, 
          as determined in Sec. 63.5335.
Allowable HAP Loss = Pounds of allowable HAP loss for the previous 12 
          months, as determined in Sec. 63.5340.

    (1) If the value of the compliance ratio is less than or equal to 
1.00, your affected source was in compliance with the applicable HAP 
emission limits of this subpart for the previous month.
    (2) If the value of the compliance ratio is greater than 1.00, your 
affected source was deviating from compliance with the applicable HAP 
emission limits of this subpart for the previous month.



Sec. 63.5335  How do I determine the actual HAP loss?

    (a) This section describes the information and procedures you must 
use to determine the actual HAP loss from your leather finishing 
operation. By the fifteenth of each month, you must determine the actual 
HAP loss in pounds from your leather finishing operation for the 
previous month.
    (b) Use one of the procedures listed in either paragraph (b)(1) or 
(b)(2) of this section for determining the actual HAP loss from your 
affected sources. Regardless of which procedure is used to determine HAP 
loss, each source is still required to maintain a written or printed log 
that documents the total quantity of solvents/finishes used each month 
in the process and the mass fraction of HAP in each solvent/finish.
    (1) Measure Finish as Applied. Use a finish inventory log to record 
the pounds of each type of finish applied for each leather product 
process operation and the mass fraction of HAP in each applied finish. 
Figure 1 of this subpart shows an example log for recording the minimum 
information necessary to determine your finish usage and HAP loss. The 
finish inventory log must contain, at a minimum, the information for 
each type of finish applied listed in paragraphs (b)(1)(i) through (vii) 
of this section:
    (i) Finish type;
    (ii) Pounds (or density and volume) of each finish applied to the 
leather;
    (iii) Mass fraction of HAP in each applied finish;
    (iv) Date of the recorded entry;
    (v) Time of the recorded entry;
    (vi) Name of the person recording the entry;
    (vii) Product process operation type.
    (2) Chemical Inventory Mass Balance. Determine the actual monthly 
HAP loss from your affected source through mass balance calculations. 
You must follow your detailed mass balance procedures and calculations 
in your plan for demonstrating compliance in accordance with Sec. 
63.5325. The HAP mass balance must be based on a detailed inventory of 
stored chemicals at the beginning and end of each month, and business 
purchasing records to indicate additions to the inventory of chemical 
supplies. The net loss of chemicals used for finish applications is 
determined by subtracting the end of the month chemical inventory from 
the beginning of the month chemical inventory and adding the quantities 
of all chemicals purchased during the same 1-month period. In situations 
when an excess amount of finish is formulated, you must have documented 
procedures on how the excess amount is accounted for in the mass 
balance.
    (c) To determine the pounds of HAP loss for the previous month, you 
must first determine the pounds of HAP loss from each finish application 
according to paragraph (c)(1) or (2) of this section.
    (1) For facilities not using add-on emission control devices, the 
entire HAP content of the finishes are assumed to be released to the 
environment. Using the finish inventory log, multiply the pounds of each 
recorded finish usage by the corresponding mass fraction of HAP in the 
finish. The result is the HAP loss in pounds from

[[Page 883]]

each finish application. Sum the pounds of HAP loss from all finish 
applications recorded during the previous month to determine the total 
monthly HAP loss in pounds from your finishing operation.
    (2) For facilities using add-on emission control devices, the finish 
inventory log and the emission reduction efficiency of the add-on 
capture and control devices can be used to determine the net HAP loss in 
pounds. The emission reduction efficiency for a control device must be 
determined from a performance test conducted in accordance with 
Sec. Sec. 63.5375 and 63.5380. Using the finish inventory log, multiply 
the pounds of each recorded finish usage by the corresponding mass 
fraction of HAP in the finish. The result is the gross HAP loss in 
pounds from each finish application prior to the add-on control device. 
Multiply the gross HAP loss by the percent emission reduction achieved 
by the add-on control device and then subtract this amount from the 
gross HAP loss. The result is the net HAP loss in pounds from each 
finish application. Sum the pounds of net HAP loss from all finish 
applications recorded during the previous month to determine the total 
monthly net HAP loss in pounds from your finishing operation.
    (d) After collecting HAP loss data for 12 months, you must also 
determine by the fifteenth of each month the annual HAP loss in pounds 
by summing the monthly HAP losses for the previous 12 months. The annual 
HAP loss is the ``actual HAP loss,'' which is used in Equation 1 of 
Sec. 63.5330 to calculate your compliance ratio, as described in Sec. 
63.5330.

[67 FR 9162, Feb. 27, 2002, as amended at 70 FR 6360, Feb. 7, 2005]



Sec. 63.5340  How do I determine the allowable HAP loss?

    (a) By the fifteenth of each month, you must determine the allowable 
HAP loss in pounds from your leather finishing operation for the 
previous month.
    (b) To determine the allowable HAP loss for your leather finishing 
operation, you must select the appropriate HAP emission limit, expressed 
in pounds of HAP loss per 1,000 square feet of leather processed, from 
Table 1 of this subpart, for each type of leather product process 
operation performed during the previous 12 months. Under the appropriate 
existing or new source column, select the HAP emission limit that 
corresponds to each type of product process operation performed during 
the previous 12 months. Next, determine the annual total of leather 
processed in 1,000's of square feet for each product process operation 
in accordance with Sec. 63.5400. Then, multiply the annual total of 
leather processed in each product process operation by the corresponding 
HAP emission limit to determine the allowable HAP loss in pounds for the 
corresponding leather product process operation. Finally, sum the pounds 
of HAP loss from all leather product process operations performed in the 
previous 12 months. Equation 1 of this section illustrates the 
calculation of allowable HAP loss as follows:
[GRAPHIC] [TIFF OMITTED] TR27FE02.004

Where:

Annual Total of Leather Processed = 1,000's of square feet of leather 
          processed in the previous 12 months in product process 
          operation ``i''.
HAP Emission Limit = From Table 1 of this subpart, the HAP emission 
          limit in pounds of HAP loss per 1,000 square feet of leather 
          processed for product process operation ``i''.
n = Number of leather product process operation types performed during 
          the previous 12 months.

    (c) The resulting ``allowable HAP loss'' is used in Equation 1 of 
Sec. 63.5330

[[Page 884]]

to calculate your compliance ratio, as described in Sec. 63.5330.



Sec. 63.5345  How do I distinguish between the two upholstery product
process operations?

    (a) Product process operations that finish leather for use in 
automobile and furniture seat coverings are categorized as an upholstery 
product process operation. There are two upholstery product process 
operations subject to the requirements of this subpart--operations with 
less than 4 grams of finish add-on per square foot, and operations with 
4 grams or more of finish add-on per square foot. You must distinguish 
between the two upholstery product process operations so that you can 
determine which HAP emission limit in Table 1 of this subpart applies to 
your affected source.
    (b) You must determine finish add-on by calculating the difference 
in mass before and after the finishing process. You may use an empirical 
method to determine the amount of finish add-on applied during the 
finishing process, as described in paragraphs (b)(1) through (4) of this 
section:
    (1) Weigh a one square foot representative section of polyester 
film, paper, cardstock, or equivalent material substrate to be finished. 
This will provide an initial mass and surface area prior to starting the 
finishing process.
    (2) Use a scale with an accuracy of at least 5 percent of the mass 
in grams of the representative section of substrate.
    (3) Upon completion of these measurements, process the 
representative section of substrate on the finishing line as you would 
for a typical section of leather.
    (4) After the finishing and drying process, weigh the representative 
section of substrate to determine the final mass. Divide the net mass in 
grams gained on the representative section by its surface area in square 
feet to determine grams per square foot of finish add-on. Equation 1 of 
this section illustrates this calculation, as follows:
[GRAPHIC] [TIFF OMITTED] TR27FE02.005

Where:

Finish Add-On = Grams per square foot of finish add-on applied to a 
          representative section of polyester film or equivalent 
          material substrate.
Final Mass = Final mass in grams of representative section of polyester 
          film or equivalent material substrate, after finishing and 
          drying.
Initial Mass = Initial mass in grams of representative section of 
          polyester film or equivalent material substrate, prior to 
          finishing.
Surface Area = Surface area in square feet of a representative section 
          of polyester film or equivalent material substrate.

    (c) Any appropriate engineering units may be used for determining 
the finish add-on. However, finish add-on results must be converted to 
the units of grams of finish add-on per square foot of leather 
processed. If multiple representative leather sections are analyzed, 
then use the average of these measurements for selecting the appropriate 
product process operation.
    (d) For each leather product with a unique finish application, you 
must maintain records to support how the leather product was categorized 
to a product process operations type. You must repeat the leather 
product categorization to a product process operation type no less 
frequently than once every 5 years if the applied finish chemical 
characteristics of the leather product have not changed, or when the 
applied finish chemical characteristics of the leather product change, 
whichever is sooner.

[67 FR 9162, Feb. 27, 2002, as amended at 70 FR 6360, Feb. 7, 2005]

[[Page 885]]



Sec. 63.5350  How do I distinguish between the water-resistant/specialty
and nonwater-resistant leather product process operations?

    (a) Product process operations that finish leather for nonupholstery 
use are categorized as either water-resistant/specialty or nonwater-
resistant product process operations. You must distinguish between the 
water-resistant/specialty and nonwater-resistant product process 
operations so that you can determine which HAP emission limit in Table 1 
of this subpart applies to your affected source. Water-resistant and 
nonwater-resistant product process operations for nonupholstery use can 
be distinguished using the methods described in paragraph (b) of this 
section. Specialty leather product process operations for nonupholstery 
use can be distinguished using the criteria described in paragraph (c) 
of this section.
    (b) To determine whether your product process operation produces 
water-resistant or nonwater-resistant leather, you must conduct the 
Maeser Flexes test method according to American Society for Testing and 
Materials (ASTM) Designation D2099-00 (incorporated by reference-see 
Sec. 63.14) or a method approved by the Administrator.
    (1) Statistical analysis of initial water penetration data performed 
to support ASTM Designation D2099-00 indicates that poor quantitative 
precision is associated with this testing method. Therefore, at a 
minimum, 36 leather substrate samples (i.e., three sections of leather 
substrate from at least 12 sides of leather), must be tested to 
determine the water-resistant characteristics of the leather. You must 
average the results of these tests to determine the final number of 
Maeser Flexes prior to initial water penetration.
    (2) Results from leather samples indicating an average of 5,000 
Maeser Flexes or more is considered a water-resistant product process 
operation, and results indicating less than 5,000 Maeser Flexes is 
considered a nonwater-resistant product process operation. However, 
leather samples resulting in less than 5,000 Maeser Flexes may be 
categorized as specialty leather in paragraph (c) of this section.
    (3) For each leather product with a unique finish application, you 
must maintain records to support how the leather product was categorized 
to a product process operations type. You must repeat the leather 
product categorization to a product process operation type no less 
frequently than once every 5 years if the applied finish chemical 
characteristics of the leather product have not changed, or when the 
applied finish chemical characteristics of the leather product do 
change, whichever is sooner.
    (c) To determine whether your product process operation produces 
specialty leather, you must meet the criteria in paragraphs (c)(1) and 
(2), or (c)(3) of this section:
    (1) The leather must be a select grade of chrome tanned, bark 
retanned, or fat liquored leather.
    (2) The leather must be retanned through the application of grease, 
waxes, and oil in quantities greater than 12 percent of the dry leather 
weight. Specialty leather is also finished with higher solvent-based 
finishes that provide rich color, luster, or an oily/tacky feel. 
Specialty leather products may include, but are not limited to, 
specialty shoe leather and top grade football leathers.
    (3) The leather must be a high-quality dress or performance shoe 
leather that can withstand one of the visual tests in paragraph 
(c)(3)(i) or (ii) of this section:
    (i) Moisture injection into the leather using vacuum mulling without 
signs of blistering.
    (ii) Prolonged ironing at 200 [deg]F for smoothing out surface 
roughness without finish lift off.
    (4) For each leather product with a unique finish application, you 
must maintain records to support how the leather product was categorized 
to a product process operations type. You must repeat the leather 
product categorization to a product process operation type no less 
frequently than once every 5 years if the applied finish chemical 
characteristics of the leather product have not changed, or when the 
applied finish chemical characteristics

[[Page 886]]

of the leather product do change, whichever is sooner.

[67 FR 9162, Feb. 27, 2002, as amended at 70 FR 6360, Feb. 7, 2005]



Sec. 63.5355  How do I monitor and collect data to demonstrate
continuous compliance?

    (a) You must monitor and collect data according to this section.
    (b) You must collect data at all required intervals as specified in 
your plan for demonstrating compliance as specified at Sec. 63.5325.
    (c) For emission control devices, except for monitor malfunctions, 
associated repairs, and required quality assurance or control activities 
(including, as applicable, calibration checks and required zero and span 
adjustments), you must monitor continuously (or collect data at all 
required intervals) at all times that the affected source is operating.
    (d) You may not use data recorded during monitoring malfunctions, 
associated repairs, and required quality assurance or control activities 
in data averages and calculations used to report emission or operating 
levels, nor may such data be used in fulfilling a minimum data 
availability requirement, if applicable. You must use all the data 
collected during all other periods in assessing the compliance ratio, 
and, if an emission control device is used, in assessing the operation 
of the control device.



Sec. 63.5360  How do I demonstrate continuous compliance with the
emission standards?

    (a) You must demonstrate continuous compliance with the emission 
standards in Sec. 63.5305 by following the requirements in paragraphs 
(a)(1) and (2) of this section:
    (1) You must collect and monitor data according to the procedures in 
your plan for demonstrating compliance as specified in Sec. 63.5325.
    (2) If you use an emission control device, you must collect the 
monitoring data according to 40 CFR part 63, subpart SS.
    (3) You must maintain your compliance ratio less than or equal to 
1.00, as specified at Sec. 63.5330.
    (b) You must report each instance in which you did not meet the 
emission standards in Sec. 63.5305. This includes periods of startup, 
shutdown, and malfunction. These deviations must be reported according 
to the requirements in Sec. 63.5420(b).
    (c) You must conduct the initial compliance demonstration before the 
compliance date that is specified for your source in Sec. 63.5295.

               Testing and Initial Compliance Requirements



Sec. 63.5375  When must I conduct a performance test or initial 
compliance demonstration?

    You must conduct performance tests after the installation of any 
emission control device that reduces HAP emissions and can be used to 
comply with the HAP emission requirements of this subpart. You must 
complete your performance tests not later than 60 calendar days before 
the end of the 12-month period used in the initial compliance 
determination.



Sec. 63.5380  How do I conduct performance tests?

    (a) Each performance test must be conducted according to the 
requirements in Sec. 63.7(e) and the procedures of Sec. 63.997(e)(1) 
and (2).
    (b) You may not conduct performance tests during periods of startup, 
shutdown, or malfunction, as specified in Sec. 63.7(e)(1).
    (c) You must conduct three separate test runs for each performance 
test required in this section, as specified in Sec. 63.7(e)(3). Each 
test run must last at least 1 hour.



Sec. 63.5385  How do I measure the quantity of finish applied to
the leather?

    (a) To determine the amount of finish applied to the leather, you 
must measure the mass, or density, and volume of each applied finish.
    (b) Determine the mass of each applied finish with a scale 
calibrated to an accuracy of at least 5 percent of the amount measured. 
The quantity of all finishes used for finishing operations must be 
weighed or have a predetermined weight.
    (c) Determine the density and volume of each applied finish 
according to the

[[Page 887]]

criteria listed in paragraphs (c)(1) through (3) of this section:
    (1) Determine the density of each applied finish in pounds per 
gallon in accordance with Sec. 63.5395. The finish density will be used 
to convert applied finish volumes from gallons into mass units of 
pounds.
    (2) Volume measurements of each applied finish can be obtained with 
a flow measurement device. For each flow measurement device, you must 
perform the items listed in paragraphs (c)(2)(i) through (v) of this 
section:
    (i) Locate the flow sensor and other necessary equipment such as 
straightening vanes in or as close to a position that provides a 
representative flow.
    (ii) Use a flow sensor with a minimum tolerance of 2 percent of the 
flow rate.
    (iii) Reduce swirling flow or abnormal velocity distributions due to 
upstream and downstream disturbances.
    (iv) Conduct a flow sensor calibration check at least semiannually.
    (v) At least monthly, inspect all components for integrity, all 
electrical connections for continuity, and all mechanical connections 
for leakage.
    (3) Volume measurements of each applied finish can be obtained with 
a calibrated volumetric container with an accuracy of at least 5 percent 
of the amount measured.



Sec. 63.5390  How do I measure the HAP content of a finish?

    (a) To determine the HAP content of a finish, the reference method 
is EPA Method 311 of appendix A of 40 CFR part 63. You may use EPA 
Method 311, an alternative method approved by the Administrator, or any 
other reasonable means for determining the HAP content. Other reasonable 
means of determining HAP content include, but are not limited to, a 
material safety data sheet (MSDS) or a manufacturer's hazardous air 
pollutant data sheet. If the HAP content is provided on a MSDS or a 
manufacturer's data sheet as a range of values, then the highest HAP 
value of the range must be used for the determination of compliance to 
this standard. This value must be entered on the finish log for each 
type of finish applied. You are not required to test the materials that 
you use, but the Administrator may require a test using EPA Method 311 
(or another approved method) to confirm the reported HAP content. 
However, if the results of an analysis by EPA Method 311 are different 
from the HAP content determined by another means, the EPA Method 311 
results will govern compliance determinations.
    (b) You may use the weighted average of the HAP content analysis as 
determined in paragraph (a) of this section for each finish when you 
perform one of the actions listed in paragraphs (b)(1) and (2) of this 
section:
    (1) Mix your own finishes on site.
    (2) Mix new quantities of finish with previous quantities of finish 
that may have a different HAP content.



Sec. 63.5395  How do I measure the density of a finish?

    (a) To determine the density of a finish, the reference method is 
EPA Method 24 of appendix A of 40 CFR part 60. You may use EPA Method 
24, an alternative method approved by the Administrator, or any other 
reasonable means for determining the density of a finish. Other 
reasonable means of determining density include, but are not limited to, 
an MSDS or a manufacturer's hazardous air pollutant data sheet. If the 
density is provided on a MSDS or a manufacturer's data sheet as a range 
of values, then the highest density value of the range must be used for 
the determination of compliance to this standard. This value must be 
entered on the finish log for each type of finish applied. You are not 
required to test the materials that you use, but the Administrator may 
require a test using EPA Method 24 (or another approved method) to 
confirm the reported density. However, if the results of an analysis by 
EPA Method 24 are different from the density determined by another 
means, the EPA Method 24 results will govern compliance determinations.
    (b) You may use the weighted average of finish densities as 
determined in paragraph (a) of this section for each finish when you 
perform one of the actions listed in paragraphs (b)(1) and (2) of this 
section:
    (1) Mix your own finishes on site.

[[Page 888]]

    (2) Mix new quantities of finish with previous quantities of finish 
that may have different densities.
    (c) Equation 1 of this section may be used to determine the weighted 
average of finish densities, as follows:
[GRAPHIC] [TIFF OMITTED] TR27FE02.006

Where:

Average Weighted Density = The average weighted density of applied 
          finishes in pounds per gallon.
Mass = Pounds of finish ``i'' applied.
Density = The density of finish ``i'' in pounds per gallon.
n = Number of finish types applied.



Sec. 63.5400  How do I measure the quantity of leather processed?

    (a) This section describes the information and procedures you must 
use to determine the quantity of leather processed at your affected 
source.
    (1) To determine the surface area (i.e., quantity) of leather 
substrate processed each month at your source for each product process 
operation, follow the procedures in your plan for demonstrating 
compliance. You must consistently measure the surface area of processed 
leather substrate at one of the manufacturing locations listed in 
paragraph (a)(1)(i) or (ii) of this section:
    (i) Measure the surface area of processed leather upon exiting the 
leather finishing operation.
    (ii) Measure the surface area of processed leather upon shipment 
from the source.
    (2) By the fifteenth of each month, you must determine the quantity 
of leather processed in 1,000's of square feet for each product process 
operation during the previous month. After collecting data on the amount 
of leather processed for 12 months, you must also determine by the 
fifteenth of each month the annual total of leather processed in 1,000's 
of square feet for each product process operation by summing the monthly 
quantities of leather processed in each product process operation for 
the previous 12 months. The ``annual total of leather processed'' in 
each product process operation is used in Equation 1 of Sec. 63.5340 to 
calculate your allowable HAP loss as described in Sec. 63.5340. Your 
allowable HAP loss is then subsequently used to calculate your 
compliance ratio as described in Sec. 63.5330.
    (b) To determine the surface area of leather processed at your 
source for each product process operation, you must use one of the 
methods listed in paragraphs (b)(1) and (2) of this section:
    (1) Premeasured leather substrate sections being supplied by another 
manufacturer as an input to your finishing process.
    (2) Measure the surface area of each piece of processed or shipped 
leather with a computer scanning system accurate to 0.1 square feet. The 
computer scanning system must be initially calibrated for minimum 
accuracy to the manufacturer's specifications. For similar leather 
production runs, use an average based on a minimum of 500 pieces of 
leather in lieu of individual measurements.
    (c) Except as provided in paragraph (d) of this section, you must 
include the surface area of each piece of processed leather only once 
when determining the monthly quantity of leather processed, regardless 
of the number of times a piece of leather is reprocessed through a 
portion of the finishing operations.
    (d) If a piece of leather is completely stripped of all applied 
finishes and reprocessed through the entire finishing operation as if it 
were a new piece of leather, you may recount the surface

[[Page 889]]

area of leather reprocessed when determining the monthly quantity of 
leather processed.

                   Other Requirements and Information



Sec. 63.5450  What parts of the General Provisions apply to me?

    Table 2 of this subpart shows which parts of the General Provisions 
in Sec. Sec. 63.1 through 63.15 apply to you.



Sec. 63.5455  Who administers this subpart?

    (a) This subpart can be administered by us, the United States 
Environmental Protection Agency (U.S. EPA), or a delegated authority 
such as your State, local, or tribal agency. If the U.S. EPA 
Administrator has delegated authority to your State, local, or tribal 
agency, then that agency has the primary authority to administer and 
enforce this subpart. You should contact your U.S. EPA Regional Office 
to find out if the authority to implement and enforce this subpart is 
delegated to your State, local, or tribal agency.
    (b) In delegating implementation and enforcement authority of this 
subpart to a State, local, or tribal agency under subpart E of this 
part, the authorities contained in paragraph (c) of this section are 
retained by the Administrator of U.S. EPA and are not transferred to the 
State, local, or tribal agency.
    (c) The authorities that will not be delegated to State, local, or 
tribal agencies are listed in paragraphs (c)(1) through (4) of this 
section:
    (1) Approval of alternatives to the emission standards in Sec. 
63.5305 under Sec. 63.6(g).
    (2) Approval of major alternatives to test methods under Sec. 
63.7(e)(2)(ii) and (f) and as defined in Sec. 63.90.
    (3) Approval of major alternatives to monitoring under Sec. 63.8(f) 
and as defined in Sec. 63.90.
    (4) Approval of major alternatives to recordkeeping and reporting 
under Sec. 63.10(f) and as defined in Sec. 63.90.



Sec. 63.5460  What definitions apply to this subpart?

    Terms used in this subpart are defined in the Clean Air Act, Sec. 
63.2, and in this section as follows:
    Area source means any stationary source of hazardous air pollutants 
that is not a major source as defined in this part.
    Compliance ratio means the ratio of the actual HAP loss from the 
previous 12 months to the allowable HAP loss from the previous 12 
months. Equation 1 in Sec. 63.5330 is used to calculate this value. If 
the value is less than or equal to 1.00, the source is in compliance. If 
the value is greater than 1.00, the source is deviating from compliance.
    Deviation means any instance in which an affected source subject to 
this subpart, or an owner or operator of such a source:
    (1) Fails to meet any requirement or obligation established by this 
subpart, including but not limited to any emission limits or work 
practice standards.
    (2) Fails to meet any emission limits, operating limits, or work 
practice standards in this subpart during startup, shutdown, or 
malfunction, regardless of whether or not such failure is permitted by 
this subpart.
    Drying means the process of removing all but equilibrium moisture 
from the leather. Drying methods currently in use include: toggling, 
hanging, pasting, and vacuum drying.
    Finish add-on means the amount of solid material deposited on the 
leather substrate due to finishing operations. Typically, the solid 
deposition is a dye or other chemical used to enhance the color and 
performance of the leather. Finish add-on is quantified as mass per 
surface area of substrate, such as grams of finish add-on per square 
foot of leather substrate.
    Hazardous air pollutants (HAP) means any substance or mixture of 
substances

[[Page 892]]

listed as a hazardous air pollutant under section 112(b) of the Clean 
Air Act.
    Leather means the pelt or hide of an animal which has been 
transformed by a tanning process into a nonputrescible and useful 
material.
    Leather finishing means a single process or group of processes used 
to adjust and improve the physical and aesthetic characteristics of the 
leather surface through the multistage application of a coating 
comprised of dyes, pigments, film-forming materials, and performance 
modifiers dissolved or suspended in liquid carriers.
    Leather substrate means a nonputrescible leather surface intended 
for the application of finishing chemicals and materials. The leather 
substrate may be a continuous piece of material such as side leather or 
may be a combination of smaller leather pieces and leather fibers, which 
when joined together, form an integral composite leather material.
    Leather tanning means the processes, commonly referred to as wet 
operations, used to purify and stabilize the collagen content of the 
hide. Wet operations are divided into three phases, the beamhouse 
(includes soaking and unhairing); the tanyard (includes bating, 
pickling, tanning, trimming/siding, and splitting); and the coloring 
department (includes retanning, coloring, and atliquoring operations).
    Month means that all references to a month in this subpart refer to 
a calendar month.
    Nonwater-resistant leather means nonupholstery leather that is not 
treated with any type of waterproof finish and, thus, cannot withstand 
5,000 Maeser Flexes with a Maeser Flex Testing Machine or a method 
approved by the Administrator prior to initial water penetration. This 
leather is typically used for dress shoes, handbags, and garments.
    Product process operation means any one of the four leather 
production classifications developed for ease of compliance with this 
subpart. The four leather product process operations are as follows: 
upholstery leather with greater than or equal to 4 grams finish add-on 
per square foot, upholstery leather with less than 4 grams finish add-on 
per square foot, water-resistant/specialty leather, and nonwater-
resistant leather.
    Specialty leather means a select grade of chrome tanned, bark 
retanned, or fat liquored leather that is retanned through the 
application of grease, waxes, and oil in quantities greater than 12 
percent of the dry leather weight or high-quality dress or performance 
shoe leather that can withstand one or more of the following visual 
tests: moisture injection into the leather using vacuum mulling without 
signs of blistering, or prolonged ironing at 200 [deg]F for smoothing 
out surface roughness without finish lift off. Specialty leather is also 
finished with higher solvent-based finishes that provide rich color, 
luster, or an oily/tacky feel. Specialty leather products are generally 
low volume, high-quality leather, such as specialty shoe leather and top 
grade football leathers.
    Upholstery leather (greater than or equal to 4 grams finish add-on 
per square foot) means an upholstery leather with a final finish add-on 
to leather ratio of 4 or more grams of finish per square foot of 
leather. These types of finishes are used primarily for automobile 
seating covers. These finishes tend to be aqueous-based.
    Upholstery leather (less than 4 grams finish add-on per square foot) 
means an upholstery leather with a final finish add-on to leather ratio 
of less than 4 grams of finish per square foot of leather. These types 
of finishes are typically used for furniture seating covers. The 
finishes tend to be solvent-based and leave a thinner, softer, and more 
natural leather texture.
    Vacuum mulling means the injection of water into the leather 
substrate using a vacuum process to increase the moisture content of the 
leather.
    Water-resistant leather means nonupholstery leather that has been 
treated with one or more waterproof finishes such that the leather can 
withstand 5,000 or more Maeser Flexes with a Maeser Flex Testing Machine 
or a method approved by the Administrator prior to initial water 
penetration. This leather is used for outerwear, boots and outdoor 
applications.

    Source: 67 FR 40055, June 11, 2002, unless otherwise noted.

                        What This Subpart Covers



Sec. 63.5480  What is the purpose of this subpart?

    This subpart establishes emission limits, operating limits, and work 
practice standards for hazardous air pollutants (HAP) emitted from 
cellulose products manufacturing operations. Carbon disulfide, carbonyl 
sulfide, ethylene oxide, methanol, methyl chloride, propylene oxide, and 
toluene are the HAP emitted in the greatest quantities from cellulose 
products manufacturing operations. This subpart also establishes 
requirements to demonstrate initial and continuous compliance with the 
emission limits, operating limits, and work practice standards.



Sec. 63.5485  Am I subject to this subpart?

    You are subject to this subpart if you own or operate a cellulose 
products manufacturing operation that is located at a major source of 
HAP emissions.
    (a) Cellulose products manufacturing includes both the Miscellaneous 
Viscose Processes source category and the Cellulose Ethers Production 
source category. The Miscellaneous Viscose Processes source category 
includes all of the operations that use the viscose process. These 
operations include the cellulose food casing, rayon, cellulosic sponge, 
and cellophane operations, as

[[Page 896]]

defined in Sec. 63.5610. The Cellulose Ethers Production source 
category includes all of the cellulose ether operations, as defined in 
Sec. 63.5610, that use the cellulose ether process.
    (b) A major source of HAP is any stationary source or group of 
stationary sources located within a contiguous area and under common 
control that emits or has the potential to emit any single HAP at a rate 
of 9.1 megagrams per year (Mg/yr) (10 tons per year (tpy)) or more or 
any combination of HAP at a rate of 23 Mg/yr (25 tpy) or more.
    (c) The provisions of this subpart do not apply to research and 
development facilities, as defined in section 112(b)(7) of the Clean Air 
Act (CAA), regardless of whether the facilities are located at the same 
plant site as an operation subject to the provisions of this subpart.
    (d) For cellulose ether operations, the applicability provisions in 
paragraph (d)(1) or (2) of this section apply.
    (1) The applicability provisions in Sec. Sec. 63.100(a) through (f) 
and 63.160 apply if you are complying with the equipment leak provisions 
of subpart H of this part.
    (2) The applicability provisions in Sec. 63.1019 apply if you are 
complying with the equipment leak provisions in subpart UU of this part.
    (e) For cellulose ether operations, the applicability provisions in 
Sec. Sec. 63.100(a) through (f) and 63.110(a), (e) and (h) apply if you 
are complying with the wastewater provisions in subparts F and G of this 
part.



Sec. 63.5490  What parts of my plant does this subpart cover?

    (a) This subpart applies to each new, reconstructed, or existing 
affected source for the Miscellaneous Viscose Processes and Cellulose 
Ethers Production source categories.
    (b) The affected source for the Miscellaneous Viscose Processes 
source category is each cellulose food casing, rayon, cellulosic sponge, 
or cellophane operation, as defined in Sec. 63.5610. The affected 
source for the Cellulose Ethers Production source category is each 
cellulose ether operation, as defined in Sec. 63.5610.
    (c) You must consider storage vessels to be part of your process 
unit, as defined in Sec. 63.5610, under either of the conditions 
described in paragraphs (c)(1) and (2) of this section. Otherwise, you 
may assign your storage vessels according to paragraph (c)(3) or (4) of 
this section.
    (1) The input to the storage vessel from your viscose process or 
cellulose ether process (either directly or through other storage 
vessels assigned to your process unit) is greater than or equal to the 
input from any other process.
    (2) The output from the storage vessel to your viscose process or 
cellulose ether process (either directly or through other storage 
vessels assigned to your process unit) is greater than or equal to the 
output to any other process.
    (3) If the greatest input to and/or output from a shared storage 
vessel is the same for two or more processes, including at least one 
viscose process or cellulose ether process, you may assign the storage 
vessel to any process unit that has the greatest input or output.
    (4) If the use varies from year to year, then you must base the 
determination on the utilization that occurred during the year preceding 
June 11, 2002 or, if the storage vessel was not operating during that 
year, you must base the use on the expected use for the first 5-year 
period after startup. You must include this determination in the 
Notification of Compliance Status Report specified in Table 7 to this 
subpart.
    (d) An affected source is a new affected source if you began 
construction of the affected source after August 28, 2000 and you met 
the applicability criteria in Sec. 63.5485 at the time you began 
construction.
    (e) An affected source is reconstructed if you meet the criteria as 
defined in Sec. 63.2.
    (f) An affected source is existing if it is not new or 
reconstructed.
    (g) For the purposes of this subpart, the definitions of new and 
existing affected source in paragraphs (d) through (f) of this section 
supersede the definitions of new and existing affected source in 
subparts F, G, H, U and UU of this part.

    (3) You must calculate the control efficiency for each control 
device for

[[Page 900]]

each test run using Equation 3 of this section:
[GRAPHIC] [TIFF OMITTED] TR11JN02.006

Where:

CE = control efficiency, percent.
ERi = total emission rate of organic HAP (ERHAPt) 
          or sulfide (ERsulft) in the inlet vent stream of

the control efficiency of the flare or the outlet organic HAP 
concentration. If you have previously conducted a compliance 
demonstration for a flare using the techniques specified in paragraphs 
(f)(1) through (3) of this section, you may use that compliance 
demonstration to satisfy the requirements of this paragraph if either no 
deliberate process changes have been made since the compliance 
demonstration, or the results of the compliance demonstration reliably 
demonstrate compliance despite process changes.
    (1) Conduct a visible emission test using the techniques specified 
in Sec. 63.11(b)(4);

the process change and incorporate this information in their material 
balance.
    (4) Cellophane operations that use recovery devices to meet the 95 
percent toluene emission limit in Table 1 to this subpart must determine 
the quantity of toluene fed to the process and the toluene recovered 
using the solvent recovery device and incorporate this information in 
their material balance.
    (5) Using the pertinent material balance information obtained

that applies to you according to the requirements in paragraphs (i)(1) 
through (9) of this section.
    (1) For continuous, batch, and combinations of continuous and batch 
process vents, establish your site-specific operating limit using the 
procedures in Sec. 63.505(c), except that, if you demonstrate initial 
compliance using a month-long compliance demonstration, references to 
``performance test'' mean ``compliance demonstration'' for purposes of 
this subpart.

                   Continuous Compliance Requirements



Sec. 63.5555  How do I demonstrate continuous compliance with the
emission limits, operating limits, and work practice standards?

    (a) You must demonstrate continuous compliance with each emission 
limit, operating limit, and work practice standard in Tables 1 and 2 to 
this subpart that applies to you according to methods specified in 
Tables 5 and 6 to this subpart.
    (b) You must report each instance in which you were not in 
continuous compliance (as specified in Tables 5 and 6 to this subpart) 
with each emission limit, each operating limit, and each work practice 
standard that apply to you. This includes periods of startup, shutdown, 
and malfunction. These instances are deviations from the emission 
limits, operating limits, and work practice standards in this subpart. 
These deviations must be reported according to the requirements in Sec. 
63.5580.
    (c) [Reserved]
    (d) Consistent with Sec. Sec. 63.6(e) and 63.7(e)(1), deviations 
that occur during a period of startup, shutdown, or malfunction are not 
violations if you demonstrate to the Administrator's satisfaction that 
you were operating in accordance with Sec. 63.6(e)(1). The 
Administrator will determine whether deviations that occur during a 
period you identify as a startup, shutdown, or malfunction are 
violations, according to the provisions in Sec. 63.6(e).

[[Page 904]]



Sec. 63.5560  How do I monitor and collect data to demonstrate
continuous compliance?

    (a) You must monitor and collect data according to this section.
    (b) Except for monitor malfunctions, associated repairs, and 
required quality assurance or control activities (including, as 
applicable, calibration checks and required zero and span adjustments), 
you must monitor continuously (or collect data at all required 
intervals) at all times that the affected source is operating, including 
periods of startup, shutdown, and malfunction.
    (c) You may not use data recorded during monitoring malfunctions, 
associated repairs, required quality assurance or control activities, 
and periods of no flow for all or a portion of an affected source in 
data averages and calculations used to report emission or operating 
levels, nor may such data be used in fulfilling a minimum data 
availability requirement, if applicable. You must use all the data 
collected during all other periods in assessing the operation of the 
control device and associated control system.
    (d) All terms in this subpart that define a period of time for 
completing required tasks (e.g., weekly, monthly, quarterly, or 
annually) refer to the standard calendar periods.
    (1) You may change time periods specified in this subpart for 
completing required tasks by mutual agreement with the Administrator, as 
specified in subpart A of this part. For example, a period could begin 
on the compliance date or another date, rather than on the first day of 
the standard calendar period. For each time period that is changed by 
agreement, the revised period must remain in effect until it is changed. 
A new request is not necessary for each recurring period.
    (2) Where the period specified for compliance is a standard calendar 
period, if the initial compliance date occurs after the beginning of the 
period, then you must comply according to the schedule specified in 
paragraph (d)(2)(i) or (ii) of this section, as appropriate.
    (i) You must comply before the end of the standard calendar period 
within which the compliance deadline occurs, if there remain at least 3 
days for tasks that must be performed weekly, at least 2 weeks for tasks 
that must be performed monthly, at least 1 month for tasks that must be 
performed quarterly, or at least 3 months for tasks that must be 
performed annually; or
    (ii) In all instances where a provision of this subpart requires 
completing a task during each of multiple successive periods, you may 
perform the required task at any time during the specified period, 
provided that the task is conducted at a reasonable interval after 
completion of the task during the previous period.

 Subpart VVVV_National Emission Standards for Hazardous Air Pollutants 
                         for Boat Manufacturing

    Source: 66 FR 44232, Aug. 22, 2001, unless otherwise noted.

                         What the Subpart Covers



Sec. 63.5680  What is the purpose of this subpart?

    (a) This subpart establishes national emission standards for 
hazardous air pollutants (HAP) for new and existing boat manufacturing 
facilities with

[[Page 941]]

resin and gel coat operations, carpet and fabric adhesive operations, or 
aluminum recreational boat surface coating operations. This subpart also 
establishes requirements to demonstrate initial and continuous 
compliance with the emission standards.



Sec. 63.5683  Does this subpart apply to me?

    (a) This subpart applies to you if you meet both of the criteria 
listed in paragraphs (a)(1) and (2) of this section.
    (1) You are the owner or operator of a boat manufacturing facility 
that builds fiberglass boats or aluminum recreational boats.
    (2) Your boat manufacturing facility is a major source of HAP either 
in and of itself, or because it is collocated with other sources of HAP, 
such that all sources combined constitute a major source.
    (b) A boat manufacturing facility is a facility that manufactures 
hulls or decks of boats from fiberglass or aluminum, or assembles boats 
from premanufactured hulls and decks, or builds molds to make fiberglass 
hulls or decks. A facility that manufactures only parts of boats (such 
as hatches, seats, or lockers) or boat trailers is not considered a boat 
manufacturing facility for the purpose of this subpart.
    (c) A major source is any stationary source or group of stationary 
sources located within a contiguous area and under common control that 
emits or can potentially emit, considering controls, in the aggregate, 
9.1 megagrams (10 tons) or more per year of a single HAP or 22.7 
megagrams (25 tons) or more per year of a combination of HAP.
    (d) This subpart does not apply to aluminum coating operations on 
aluminum boats intended for commercial or military (nonrecreational) 
use, antifoulant coatings, assembly adhesives, fiberglass hull and deck 
coatings, research and development activities, mold sealing and release 
agents, mold stripping and cleaning solvents, and wood coatings as 
defined in Sec. 63.5779. This subpart does not apply to materials 
contained in handheld aerosol cans.



Sec. 63.5686  How do I demonstrate that my facility is not a major
source?

    You can demonstrate that your facility is not a major source by 
using the procedures in either paragraph (a) or (b) of this section.
    (a) Emission option. You must demonstrate that your facility does 
not emit, and does not have the potential to emit as defined in Sec. 
63.2, considering federally enforceable permit limits, 9.1 megagrams (10 
tons) or more per year of a single HAP or 22.7 megagrams (25 tons) or 
more per year of a combination of HAP. To calculate your facility's 
potential to emit, you must include emissions from the boat 
manufacturing facility and all other sources that are collocated and 
under common ownership or control with the boat manufacturing facility.
    (b) Material consumption option. This option can be used if you 
manufacture either fiberglass boats or aluminum recreational boats at 
your facility. You must meet the criteria in paragraph (b)(1), (2), or 
(3) of this section and comply with the requirements in paragraph (c) of 
this section. If you initially rely on the limits and criteria specified 
in paragraph (b)(1), (2), or (3) of this section to become an area 
source, but then exceed the relevant limit (without first obtaining and 
complying with other limits that keep your potential to emit HAP below 
major source levels), your facility will then become a major source, and 
you must comply with all applicable provisions of this subpart beginning 
on the compliance date specified in Sec. 63.5695. Nothing in this 
paragraph is intended to preclude you from limiting your facility's 
potential to emit through other federally enforceable mechanisms 
available through your permitting authority.
    (1) If your facility is primarily a fiberglass boat manufacturing 
facility, you must demonstrate that you consume less than 45.4 megagrams 
per rolling 12-month period of all combined polyester-and vinylester-
based resins and gel coats (including tooling and production resins and 
gel coats, and clear gel coats), and you must demonstrate that at least 
90 percent of

[[Page 942]]

total annual HAP emissions at the facility (including emissions from 
aluminum recreational boat manufacturing or other source categories) 
originate from the fiberglass boat manufacturing materials.
    (2) If your facility is primarily an aluminum recreational boat 
manufacturing facility, you must demonstrate that it consumes less than 
18.2 megagrams per rolling 12-month period of all combined surface 
coatings, aluminum wipedown solvents, application gun cleaning solvents, 
and carpet and fabric adhesives; and you must demonstrate that at least 
90 percent of total annual HAP emissions at the facility (including 
emissions from fiberglass boat manufacturing or other source categories) 
originate from the aluminum recreational boat manufacturing materials.
    (3) If your facility is a fiberglass boat or an aluminum 
recreational boat manufacturing facility, you must demonstrate that the 
boat manufacturing materials consumed per rolling 12-month period 
contain a total of less than 4.6 megagrams of any single HAP and less 
than 11.4 megagrams of all combined HAP, and you must demonstrate that 
at least 90 percent of total annual HAP emissions at the facility 
(including emissions from other source categories) originate from these 
boat manufacturing materials.
    (c) If you use the material consumption option described in 
paragraph (b) of this section to demonstrate that you are not a major 
source, you must comply with the requirements of paragraphs (c)(1) 
through (3) of this section.
    (1) If your facility has HAP emissions that do not originate from 
boat manufacturing operations or materials described in paragraph (b), 
then you must keep any records necessary to demonstrate that the 90 
percent criterion is met.
    (2) A rolling 12-month period includes the previous 12 months of 
operation. You must maintain records of the total amount of materials 
described in paragraph (b) of this section used each month, and, if 
necessary, the HAP content of each material and the calculation of the 
total HAP consumed each month. Because records are needed for a 12-month 
period, you must keep records beginning no later than 12 months before 
the compliance date specified in Sec. 63.5695. Records must be kept for 
5 years after they are created.
    (3) In determining whether the 90 percent criterion included in 
paragraph (b) of this section is met, you do not need to include 
materials used in routine janitorial, building, or facility grounds 
maintenance; personal uses by employees or other persons; or products 
used for maintaining motor vehicles operated by the facility.



Sec. 63.5689  What parts of my facility are covered by this subpart?

    The affected source (the portion of your boat manufacturing facility 
covered by this subpart) is the combination of all of the boat 
manufacturing operations listed in paragraphs (a) through (f) of this 
section.
    (a) Open molding resin and gel coat operations (including pigmented 
gel coat, clear gel coat, production resin, tooling gel coat, and 
tooling resin).
    (b) Closed molding resin operations.
    (c) Resin and gel coat mixing operations.
    (d) Resin and gel coat application equipment cleaning operations.
    (e) Carpet and fabric adhesive operations.
    (f) Aluminum hull and deck coating operations, including solvent 
wipedown operations and paint spray gun cleaning operations, on aluminum 
recreational boats.



Sec. 63.5692  How do I know if my boat manufacturing facility is a new
source or an existing source?

    (a) A boat manufacturing facility is a new source if it meets the 
criteria in paragraphs (a)(1) through (3) of this section.
    (1) You commence construction of the affected source after July 14, 
2000.
    (2) It is a major source.
    (3) It is a completely new boat manufacturing affected source where 
no other boat manufacturing affected source existed prior to the 
construction of the new source.
    (b) For the purposes of this subpart, an existing source is any 
source that is not a new source.

Sec. 63.5713  How do I demonstrate compliance using compliant materials?

    (a) Compliance using the organic HAP content requirements listed in 
Table 2 to this subpart is based on a 12-month rolling average that is 
calculated at the end of every month. The first 12-month rolling-average 
period begins on the compliance date specified in Sec. 63.5695. If you

at the end of every subsequent month, review the organic HAP contents of 
the resins and gel coats used in the past 12 months in each operation. 
If all resins and gel coats used in an operation have organic HAP 
contents no greater than the applicable organic HAP content limits in 
Table 2 to this subpart, then you are in compliance with the emission 
limit specified in Sec. 63.5698 for that 12-month period for that 
operation. In addition, you do not need to complete the weighted-average 
organic HAP content calculation contained in paragraph (c) of this 
section for that operation.
    (c) At the end of every month, you must use equation 1 of this 
section to calculate the weighted-average organic HAP content for all 
resins and gel coats used in each operation in the past 12 months.

subpart, then you are in compliance with the emission limit specified in 
Sec. 63.5698.



Sec. 63.5714  How do I demonstrate compliance if I use filled resins?

    (a) If you are using a filled production resin or filled tooling 
resin, you must demonstrate compliance for the filled material on an as-
applied basis using equation 1 of this section.

exceed 46 kilograms of organic HAP per megagram of filled resin applied, 
then the filled resin is in compliance.
    (c) If the filled resin is used as a tooling resin and the value of 
PVF calculated by equation 1 of this section does not exceed 
54 kilograms of organic HAP per megagram of filled resin applied, then 
the filled resin is in compliance.

 Demonstrating Compliance for Open Molding Operations Controlled by Add-
                           On Control Devices



Sec. 63.5715  What operating limits must I meet?

    (a) For open molding operations on which you use a thermal oxidizer 
as an add-on control device, you must meet the operating limits 
specified in Table 4 to this subpart that apply to the emission capture 
system and thermal oxidizer. You must establish the operating limits 
during the performance test according to the procedures in Sec. 
63.5725. You must meet the operating limits at all times after you 
establish them.
    (b) If you use an add-on control device other than a thermal 
oxidizer, or wish to monitor an alternative parameter and comply with a 
different operating limit, you must apply to the Administrator for 
approval of alternative monitoring under Sec. 63.8(f).



Sec. 63.5716  When must I conduct a performance test?

    (a) If your source is an existing source, you must complete the add-
on control device performance test no later than the compliance date 
specified in Sec. 63.5695.
    (b) If your source is a new source, you must complete the add-on 
control device performance test no later than 180 days after the 
compliance date specified in Sec. 63.5695.
    (c) You must conduct a performance test every 5 years as part of 
renewing your 40 CFR part 70 or 71 operating permit.



Sec. 63.5719  How do I conduct a performance test?

    (a) You must capture the emissions using a permanent enclosure (such 
as a spray booth or similar containment device) and direct the captured 
emissions to the add-on control device.
    (b) You must measure emissions as specified in paragraph (b)(1) or 
(2) of this section.
    (1) If the enclosure vented to the control device is a permanent 
total enclosure as defined in Method 204 of appendix M to 40 CFR part 
51, then you may measure emissions only at the outlet of the control 
device.

[[Page 948]]

    (2) If the permanent enclosure vented to the control device is not a 
total enclosure, you must build a temporary total enclosure, as defined 
in Method 204 of appendix M to 40 CFR part 51, around the permanent 
enclosure. You must then simultaneously measure emissions from the 
control device outlet and the emissions from the temporary total 
enclosure outlet. You determine compliance from the combined emissions 
from the control device outlet and the temporary total enclosure outlet.
    (c) You must conduct the control device performance test using the 
emission measurement methods specified in paragraphs (c)(1) through (4) 
of this section.
    (1) Use either Method 1 or 1A of appendix A to 40 CFR part 60, as 
appropriate, to select the sampling sites.
    (2) Use Method 2, 2A, 2C, 2D, 2F or 2G of appendix A to 40 CFR part 
60, as appropriate, to measure gas volumetric flow rate.
    (3) Use Method 18 of appendix A to 40 CFR part 60 to measure organic 
HAP emissions or use Method 25A of appendix A to 40 CFR part 60 to 
measure total gaseous organic emissions as a surrogate for total organic 
HAP emissions. If you use Method 25A, you must assume that all gaseous 
organic emissions measured as carbon are organic HAP emissions. If you 
use Method 18 and the number of organic HAP in the exhaust stream 
exceeds five, you must take into account the use of multiple 
chromatographic columns and analytical techniques to get an accurate 
measure of at least 90 percent of the total organic HAP mass emissions. 
Do not use Method 18 to measure organic HAP emissions from a combustion 
device; use instead Method 25A and assume that all gaseous organic mass 
emissions measured as carbon are organic HAP emissions.
    (4) You may use American Society for Testing and Materials (ASTM) 
D6420-99 (available for purchase from at least one of the following 
addresses: 100 Barr Harbor Drive, West Conshohocken, PA 19428-2959; or 
University Microfilms International, 300 North Zeeb Road, Ann Arbor, MI 
48106.) in lieu of Method 18 of 40 CFR part 60, appendix A, under the 
conditions specified in paragraphs (c)(4)(i) through (iii) of this 
section.
    (i) If the target compound(s) is listed in Section 1.1 of ASTM 
D6420-99 and the target concentration is between 150 parts per billion 
by volume and 100 parts per million by volume.
    (ii) If the target compound(s) is not listed in Section 1.1 of ASTM 
D6420-99, but is potentially detected by mass spectrometry, an 
additional system continuing calibration check after each run, as 
detailed in Section 10.5.3 of ASTM D6420-99, must be followed, met, 
documented, and submitted with the performance test report even if you 
do not use a moisture condenser or the compound is not considered 
soluble.
    (iii) If a minimum of one sample/analysis cycle is completed at 
least every 15 minutes.
    (d) The control device performance test must consist of three runs 
and each run must last at least 1 hour. The production conditions during 
the test runs must represent normal production conditions with respect 
to the types of parts being made and material application methods. The 
production conditions during the test must also represent maximum 
potential emissions with respect to the organic HAP content of the 
materials being applied and the material application rates.
    (e) During the test, you must also monitor and record separately the 
amounts of production resin, tooling resin, pigmented gel coat, clear 
gel coat, and tooling gel coat applied inside the enclosure that is 
vented to the control device.



Sec. 63.5722  How do I use the performance test data to demonstrate
initial compliance?

    Demonstrate initial compliance with the open molding emission limit 
as described in paragraphs (a) through (c) of this section:
    (a) Calculate the organic HAP limit you must achieve using equation 
1 of Sec. 63.5698. For determining initial compliance, the organic HAP 
limit is based on the amount of material used during the performance 
test, in megagrams, rather than during the past 12 months. Calculate the 
limit using the megagrams of resin and gel coat applied inside the 
enclosure during the

[[Page 949]]

three runs of the performance test and equation 1 of Sec. 63.5698.
    (b) Add the total measured emissions, in kilograms, from all three 
of the 1-hour runs of the performance test.
    (c) If the total emissions from the three 1-hour runs of the 
performance test are less than the organic HAP limit calculated in 
paragraph (a) of this section, then you have demonstrated initial 
compliance with the emission limit in Sec. 63.5698 for those operations 
performed in the enclosure and controlled by the add-on control device.



Sec. 63.5725  What are the requirements for monitoring and demonstrating
continuous compliance?

    (a) You must establish control device parameters that indicate 
proper operation of the control device.
    (b) You must install, operate, and maintain a continuous parameter 
monitoring system as specified in paragraphs (b)(1) through (8) of this 
section.
    (1) The continuous parameter monitoring system must complete a 
minimum of one cycle of operation for each successive 15-minute period. 
You must have a minimum of four successive cycles of operation to have a 
valid hour of data.
    (2) You must have valid data from at least 90 percent of the hours 
during which the process operated.
    (3) You must determine the average of all recorded readings for each 
successive 3-hour period of the emission capture system and add-on 
control device operation.
    (4) You must maintain the continuous parameter monitoring system at 
all times and have available necessary parts for routine repairs of the 
monitoring equipment.
    (5) You must operate the continuous parameter monitoring system and 
collect emission capture system and add-on control device parameter data 
at all times that a controlled open molding operation is being 
performed, except during monitoring malfunctions, associated repairs, 
and required quality assurance or control activities (including, if 
applicable, calibration checks and required zero and span adjustments).
    (6) You must not use emission capture system or add-on control 
device parameter data recorded during monitoring malfunctions, 
associated repairs, out-of-control periods, or required quality 
assurance or control activities when calculating data averages. You must 
use all the data collected during all other periods in calculating the 
data averages for determining compliance with the emission capture 
system and add-on control device operating limits.
    (7) You must record the results of each inspection, calibration, and 
validation check.
    (8) Any period for which the monitoring system is out-of-control, as 
defined in Sec. 63.7(d)(7), or malfunctioning, and data are not 
available for required calculations is a deviation from the monitoring 
requirements. A monitoring malfunction is any sudden, infrequent, not 
reasonably preventable failure of the continuous parameter monitoring 
system to provide valid data. Monitoring failures that are caused in 
part by poor maintenance or careless operation are not malfunctions.
    (c) Enclosure bypass line. You must meet the requirements of 
paragraphs (c)(1) and (2) of this section for each emission capture 
system enclosure that contains bypass lines that could divert emissions 
away from the add-on control device to the atmosphere.
    (1) You must monitor or secure the valve or closure mechanism 
controlling the bypass line in a nondiverting position in such a way 
that the valve or closure mechanism cannot be opened without creating a 
record that the valve was opened. The method used to monitor or secure 
the valve or closure mechanism must meet one of the requirements 
specified in paragraphs (c)(1)(i) through (iv) of this section.
    (i) Flow control position indicator. Install, calibrate, maintain, 
and operate according to the manufacturer's specifications a flow 
control position indicator that takes a reading at least once every 15 
minutes and provides a record indicating whether the emissions are 
directed to the add-on control device or diverted from the add-on 
control device. The time of occurrence and flow control position must be 
recorded, as

[[Page 950]]

well as every time the flow direction is changed. The flow control 
position indicator must be installed at the entrance to any bypass line 
that could divert the emissions away from the add-on control device to 
the atmosphere.
    (ii) Car-seal or lock-and-key valve closures. Secure any bypass line 
valve in the closed position with a car-seal or a lock-and-key type 
configuration. You must visually inspect the seal or closure mechanism 
at least once every month to ensure that the valve is maintained in the 
closed position, and the emissions are not diverted away from the add-on 
control device to the atmosphere.
    (iii) Valve closure continuous monitoring. Ensure that any bypass 
line valve is in the closed (non-diverting) position through monitoring 
of valve position at least once every 15 minutes. You must inspect the 
monitoring system at least once every month to verify that the monitor 
will indicate valve position.
    (iv) Automatic shutdown system. Use an automatic shutdown system in 
which the open molding operation is stopped when flow is diverted by the 
bypass line away from the add-on control device to the atmosphere when 
the open molding operation is running. You must inspect the automatic 
shutdown system at least once every month to verify that it will detect 
diversions of flow and shut down the open molding operation.
    (2) If any bypass line is opened, you must include a description of 
why the bypass line was opened and the length of time it remained open 
in the semiannual compliance reports required in Sec. 63.5764(d).
    (d) Thermal oxidizers. If you are using a thermal oxidizer or 
incinerator as an add-on control device, you must comply with the 
requirements in paragraphs (d)(1) through (6) of this section.
    (1) You must install a combustion temperature monitoring device in 
the firebox of the thermal oxidizer or incinerator, or in the duct 
immediately downstream of the firebox before any substantial heat 
exchange occurs. You must meet the requirements in paragraphs (b) and 
(d)(1)(i) through (vii) of this section for each temperature monitoring 
device.
    (i) Locate the temperature sensor in a position that provides a 
representative temperature.
    (ii) Use a temperature sensor with a minimum tolerance of 2.2 [deg]C 
or 0.75 percent of the temperature value, whichever is larger.
    (iii) Shield the temperature sensor system from electromagnetic 
interference and chemical contaminants.
    (iv) If a chart recorder is used, it must have a sensitivity in the 
minor division of at least 10 [deg]C.
    (v) Perform an electronic calibration at least semiannually 
according to the procedures in the manufacturer's owners manual. 
Following the electronic calibration, you must conduct a temperature 
sensor validation check in which a second or redundant temperature 
sensor placed nearby the process temperature sensor must yield a reading 
within 16.7 [deg]C of the process temperature sensor's reading.
    (vi) Conduct calibration and validation checks any time the sensor 
exceeds the manufacturer's specified maximum operating temperature range 
or install a new temperature sensor.
    (vii) At least monthly, inspect all components for integrity and all

the performance evaluation, and reporting of performance evaluation 
results.
    (3) During the performance test required by Sec. 63.5716, you must 
monitor and record the combustion temperature and determine the average 
combustion temperature for the three 1-hour test runs. This average 
temperature is the minimum operating limit for the thermal oxidizer.
    (4) Following the performance test, you must continuously monitor 
the combustion temperature and record the average combustion temperature 
no less frequently than every 15 minutes.

[[Page 951]]

    (5) You must operate the incinerator or thermal oxidizer so that the 
average combustion temperature in any 3-hour period does not fall below 
the average combustion temperature recorded during the performance test.
    (6) If the average combustion temperature in any 3-hour period falls 
below the average combustion temperature recorded during the performance 
test, or if you fail to collect the minimum data specified in paragraph 
(d)(4) of this section, it is a deviation for the operating limit in 
Sec. 63.5715.
    (e) Other control devices. If you are using a control device other a 
thermal oxidizer, then you must comply with alternative monitoring 
requirements and operating limits approved by the Administrator under 
Sec. 63.8(f).

organic HAP per kilogram of material, or

[[Page 954]]

weight fraction) of each aluminum wipedown solvent and aluminum coating 
(including primers, topcoats, clear coats, thinners, and activators). 
Use the methods in Sec. 63.5758 to determine organic HAP content.
    (b) Use the methods in Sec. 63.5758(b) to determine the solids 
content (liters of solids per liter of coating, or volume fraction) of 
each aluminum surface coating, including primers, topcoats, and clear 
coats. Keep records of the solids content.
    (c) Use the methods in Sec. 63.5758(c) to determine the density of 
each aluminum surface coating and wipedown solvent.
    (d) Compliance is based on a 12-month rolling average calculated at 
the end of every month. The first 12-month rolling-average period begins 
on the compliance date specified in Sec. 63.5695.
    (e) At the end of the twelfth month after your compliance date and 
at the end of every subsequent month, use the procedures in Sec. 
63.5749 to calculate the organic HAP from aluminum wipedown solvents per 
liter of coating solids, and use the procedures in Sec. 63.5752 to 
calculate the kilograms of organic HAP from aluminum coatings per liter 
of coating solids.
    (f) Keep records of the calculations used to determine compliance.
    (g) Approval of alternative means of demonstrating compliance. You 
may apply to the Administrator for permission to use an alternative 
means (such as an add-on control system) of limiting emissions from 
aluminum wipedown solvent and coating operations and demonstrating 
compliance with the emission limits in Sec. 63.5743(a).
    (1) The application must include the information listed in 
paragraphs (g)(1)(i) through (iii) of this section.
    (i) An engineering evaluation that compares the emissions using the 
alternative means to the emissions that would result from using the 
strategy specified in paragraphs (a) through (e) of this section. The 
engineering evaluation may include the results from an emission test 
that accurately measures the capture efficiency and control device 
efficiency achieved by the control system and the composition of the 
associated coatings so that the emissions comparison can be made.
    (ii) A proposed monitoring protocol that includes operating 
parameter values to be monitored for compliance and an explanation of 
how the operating parameter values will be established through a 
performance test.
    (iii) Details of appropriate recordkeeping and reporting procedures.
    (2) The Administrator will approve the alternative means of limiting 
emissions if the Administrator determines that HAP emissions will be no 
greater than if the source uses the procedures described in paragraphs 
(a) through (e) of this section to demonstrate compliance.
    (3) The Administrator's approval may specify operation, maintenance, 
and monitoring requirements to ensure that emissions from the regulated 
operations are no greater than those that would otherwise result from 
regulated operations in compliance with this subpart.



Sec. 63.5749  How do I calculate the organic HAP content of aluminum
wipedown solvents?

    (a) Use equation 1 of this section to calculate the weighted-average 
organic HAP content of aluminum wipedown solvents used in the past 12 
months.
[GRAPHIC] [TIFF OMITTED] TR22AU01.016

Where:

Where:

HAPSC = weighted-average organic HAP content for all aluminum 
          coating materials, kilograms of organic HAP per liter of 
          coating solids.
m = number of different aluminum primers, top coats, and clear coats 
          used in the past 12 months.

[[Page 956]]



Sec. 63.5755  How do I demonstrate compliance with the aluminum 
recreational boat surface coating spray gun cleaning work practice
standards?

    You must demonstrate compliance with the aluminum coating spray gun 
cleaning work practice standards by meeting the requirements of 
paragraph (a) or (b) of this section.
    (a) Demonstrate that solvents used to clean the aluminum coating 
spray guns contain no more than 5 percent organic HAP by weight by 
determining organic HAP content with the methods in Sec. 63.5758. Keep 
records of the organic HAP content determination.

         Methods for Determining Hazardous Air Pollutant Content



Sec. 63.5758  How do I determine the organic HAP content of materials?

    (a) Determine the organic HAP content for each material used. To 
determine the organic HAP content for each material used in your open 
molding resin and gel coat operations, carpet and fabric adhesive 
operations, or aluminum recreational boat surface coating operations, 
you must use one of the options in paragraphs (a)(1) through (6) of this 
section.
    (1) Method 311 (appendix A to 40 CFR part 63). You may use Method 
311 for determining the mass fraction of organic HAP. Use the procedures 
specified in paragraphs (a)(1)(i) and (ii) of this section when 
determining organic HAP content by Method 311.
    (i) Include in the organic HAP total each organic HAP that is 
measured to be present at 0.1 percent by mass or more for Occupational 
Safety and Health Administration (OSHA)-defined carcinogens as specified 
in 29 CFR 1910.1200(d)(4) and at 1.0 percent by mass or more for other 
compounds. For example, if toluene (not an OSHA carcinogen) is measured 
to be 0.5 percent of the material by mass, you do not need to include it 
in the organic HAP total. Express the mass fraction of each organic HAP 
you measure as a value truncated to four places after the decimal point 
(for example, 0.1234).
    (ii) Calculate the total organic HAP content in the test material by 
adding up the individual organic HAP contents and truncating the result 
to three places after the decimal point (for example, 0.123).
    (2) Method 24 (appendix A to 40 CFR part 60). You may use Method 24 
to determine the mass fraction of non-aqueous volatile matter of 
aluminum coatings and use that value as a substitute for mass fraction 
of organic HAP.
    (3) ASTM D1259-85 (Standard Test Method for Nonvolatile Content of 
Resins). You may use ASTM D1259-85 (available for purchase from ASTM) to 
measure the mass fraction of volatile matter of resins and gel coats for 
open molding operations and use that value as a substitute for mass 
fraction of organic HAP.
    (4) Alternative method. You may use an alternative test method for 
determining mass fraction of organic HAP if you obtain prior approval by 
the Administrator. You must follow the procedure in Sec. 63.7(f) to 
submit an alternative test method for approval.
    (5) Information from the supplier or manufacturer of the material. 
You may rely on information other than that generated by the test 
methods specified in paragraphs (a)(1) through (4) of this section, such 
as manufacturer's formulation data, according to paragraphs (a)(5)(i) 
through (iii) of this section.
    (i) Include in the organic HAP total each organic HAP that is 
present at 0.1

[[Page 957]]

percent by mass or more for OSHA-defined carcinogens as specified in 29 
CFR 1910.1200(d)(4) and at 1.0 percent by mass or more for other 
compounds. For example, if toluene (not an OSHA carcinogen) is 0.5 
percent of the material by mass, you do not have to include it in the 
organic HAP total.
    (ii) If the organic HAP content is provided by the material supplier 
or manufacturer as a range, then you must use the upper limit of the 
range for determining compliance. If a separate measurement of the total 
organic HAP content using the methods specified in paragraphs (a)(1) 
through (4) of this section exceeds the upper limit of the range of the 
total organic HAP content provided by the material supplier or 
manufacturer, then you must use the measured organic HAP content to 
determine compliance.
    (iii) If the organic HAP content is provided as a single value, you 
may assume the value is a manufacturing target value and actual organic 
HAP content may vary from the target value. If a separate measurement of 
the total organic HAP content using the methods specified in paragraphs 
(a)(1) through (4) of this section is less than 2 percentage points 
higher than the value for total organic HAP content provided by the 
material supplier or manufacturer, then you may use the provided value 
to demonstrate compliance. If the measured total organic HAP content 
exceeds the provided value by 2 percentage points or more, then you must 
use the measured organic HAP content to determine compliance.
    (6) Solvent blends. Solvent blends may be listed as single 
components for some regulated materials in certifications provided by 
manufacturers or suppliers. Solvent blends may contain organic HAP which 
must be counted toward the total organic HAP content of the materials. 
When detailed organic HAP content data for solvent blends are not 
available, you may use the values for organic HAP content that are 
listed in Table 5 or 6 to this subpart. You may use Table 6 to this 
subpart only if the solvent blends in the materials you use do not match 
any of the solvent blends in Table 5 to this subpart and you know only 
whether the blend is either aliphatic or aromatic. However, if test 
results indicate higher values than those listed in Table 5 or 6 to this 
subpart, then the test results must be used for determining compliance.
    (b) Determine the volume fraction solids in aluminum recreational 
boat surface coatings. To determine the volume fraction of coating 
solids (liters of coating solids per liter of coating) for each aluminum 
recreational boat surface coating, you must use one of the methods 
specified in paragraphs (b)(1) through (3) of this section. If the 
results obtained with paragraphs (b)(2) or (3) of this section do not to 
agree with those obtained according to paragraph (b)(1) of this section, 
you must use the results obtained with paragraph (b)(1) of this section 
to determine compliance.
    (1) ASTM Method D2697-86(1998) or D6093-97. You may use ASTM Method 
D2697-86(1998) or D6093-97 (available for purchase from ASTM) to 
determine the volume fraction of coating solids for each coating. Divide 
the nonvolatile volume percent obtained with the methods by 100 to 
calculate volume fraction of coating solids.
    (2) Information from the supplier or manufacturer of the material. 
You may obtain the volume fraction of coating solids for each coating 
from the supplier or manufacturer.
    (3) Calculation of volume fraction of coating solids. You may 
determine it using equation 1 of this section:
[GRAPHIC] [TIFF OMITTED] TR22AU01.019

Where:

Solids=volume fraction of coating solids, liters coating solids per 
          liter coating.
\m\volatiles=Total volatile matter content of the coating, including 
          organic HAP, volatile organic compounds, water, and exempt 
          compounds, determined according to Method 24 in appendix A of 
          40 CFR part 60, grams volatile matter per liter coating.
Davg = average density of volatile matter in the coating, 
          grams volatile matter per liter volatile matter, determined 
          from test results using ASTM Method D1475-90 (available for 
          purchase from ASTM), information from the supplier or 
          manufacturer of the material, or reference sources providing 
          density or specific gravity data for pure materials. If there

[[Page 958]]

          is disagreement between ASTM Method D1475-90 test results and 
          other information sources, the test results will take 
          precedence.

    (c) Determine the density of each aluminum recreational boat 
wipedown solvent and surface coating. Determine the density of all 
aluminum recreational boat wipedown solvents, surface coatings, 
thinners, and other additives from test results using ASTM Method D1475-
90, information from the supplier or manufacturer of the material, or

build or repair molds.
    Closed molding means any molding process in which pressure is used 
to distribute the resin through the reinforcing fabric placed between 
two mold surfaces to either saturate the fabric or fill the mold cavity. 
The pressure may be clamping pressure, fluid pressure, atmospheric 
pressure, or vacuum pressure used either alone or in combination. The 
mold surfaces may be rigid or flexible. Closed molding includes, but is 
not limited to, compression molding with sheet molding compound, 
infusion molding, resin injection molding (RIM), vacuum-assisted resin 
transfer molding (VARTM), resin transfer molding (RTM), and vacuum-
assisted compression molding. Processes in which a closed mold is used 
only to compact saturated fabric or remove air or excess resin from the 
fabric (such as in vacuum bagging), are not considered closed molding.

exposure to the elements. Gel coat layers do not contain any reinforcing 
fibers and gel coats are applied directly to mold surfaces or to a 
finished laminate.
    Hazardous air pollutant or HAP means any air pollutant listed in, or 
pursuant to section 112(b) of the Clean Air Act.
    Hazardous air pollutant content or HAP content means the amount of 
HAP contained in a regulated material at the time it is applied to the 
part being manufactured. If no HAP is added to a material as a thinner

content does not include any HAP contained in the catalyst added to the 
resin or gel coat during application to initiate curing.
    Hazardous air pollutant data sheet (HDS) means documentation 
furnished by a material supplier or an outside laboratory to provide the 
organic HAP content of the material by weight, measured using an EPA 
Method, manufacturer's formulation data, or an equivalent method. For 
aluminum coatings, the HDS also documents the solids content by volume, 
determined from the manufacturer's formulation data. The purpose of the 
HDS is to help the affected source in showing compliance with the 
organic HAP content limits contained in this subpart. The HDS must state 
the maximum total organic HAP concentration, by weight, of the material. 
It must include any organic HAP concentrations equal to or greater than 
0.1 percent by weight for individual organic HAP that are carcinogens, 
as defined by the Occupational Safety and Health Administration Hazard 
Communication Standard (29 CFR part 1910), and 1.0 percent by weight for 
all other individual organic HAP, as formulated. The HDS must also 
include test conditions if EPA Method 311 is used for determining 
organic HAP content.
    Maximum achievable control technology (MACT) model point value means 
a number calculated for open molding operations that is a surrogate for 
emissions and is used to determine if your open molding operations are 
in compliance with the provisions of this subpart. The units for MACT 
model point values are kilograms of organic HAP per megagram of resin or 
gel coat applied.
    Manufacturer's certification means documentation furnished by a 
material supplier that shows the organic HAP content of a material and 
includes a HDS.

\1\Equations calculate MACT model point value in kilograms of organic HAP per megagrams of resin or gel coat
  applied. The equations for vacuum bagging with roll-out are applicable when a facility rolls out the applied
  resin and fabric prior to applying the vacuum bagging materials. The equations for vacuum bagging without roll-
  out are applicable when a facility applies the vacuum bagging materials immediately after resin application
  without rolling out the resin and fabric. HAP% = organic HAP content as supplied, expressed as a weight-
  percent value between 0 and 100 percent.

Subpart WWWW_National Emissions Standards for Hazardous Air Pollutants: 
                Reinforced Plastic Composites Production

    Source: 68 FR 19402, Apr. 21, 2003, unless otherwise noted.

                        What This Subpart Covers



Sec. 63.5780  What is the purpose of this subpart?

    This subpart establishes national emissions standards for hazardous 
air pollutants (NESHAP) for reinforced plastic composites production. 
This subpart also establishes requirements to demonstrate initial and 
continuous compliance with the hazardous air pollutants (HAP) emissions 
standards.



Sec. 63.5785  Am I subject to this subpart?

    (a) You are subject to this subpart if you own or operate a 
reinforced plastic composites production facility that is located at a 
major source of HAP emissions. Reinforced plastic composites production 
is limited to operations in which reinforced and/or nonreinforced 
plastic composites or plastic molding compounds are manufactured using 
thermoset resins and/or gel coats that contain styrene to produce 
plastic composites. The resins and gel coats may also contain materials 
designed to enhance the chemical, physical, and/or thermal properties of 
the product. Reinforced plastic composites production also includes 
cleaning, mixing, HAP-containing materials storage, and repair 
operations associated with the production of plastic composites.
    (b) You are not subject to this subpart if your facility only 
repairs reinforced plastic composites. Repair includes the non-routine 
manufacture of individual components or parts intended to repair a 
larger item as defined in Sec. 63.5935
    (c) You are not subject to this subpart if your facility is a 
research and development facility as defined in section 112(c)(7) of the 
Clean Air Act (CAA).
    (d) You are not subject to this subpart if your reinforced plastic 
composites operations use less than 1.2 tons per year (tpy) of thermoset 
resins and gel coats that contain styrene combined.

[[Page 970]]



Sec. 63.5787  What if I also manufacture fiberglass boats or
boat parts?

    (a) If your source meets the applicability criteria in Sec. 
63.5785, and is not subject to the Boat Manufacturing NESHAP (40 CFR 
part 63, subpart VVVV), you are subject to this subpart regardless of 
the final use of the parts you manufacture.
    (b) If your source is subject to 40 CFR part 63, subpart VVVV, and 
all the reinforced plastic composites you manufacture are used in 
manufacturing your boats, you are not subject to this subpart.
    (c) If you are subject to 40 CFR part 63, subpart VVVV, and meet the 
applicability criteria in Sec. 63.5785, and produce reinforced plastic 
composites that are not used in fiberglass boat manufacture at your 
facility, all operations associated with the manufacture of the 
reinforced plastic composites parts that are not used in fiberglass boat 
manufacture at your facility are subject to this subpart, except as 
noted in paragraph (d) of this section.
    (d) Facilities potentially subject to both this subpart and 40 CFR 
part 63, subpart VVVV may elect to have the operations in paragraph (c) 
of this section covered by 40 CFR part 63, subpart VVVV, in lieu of this 
subpart, if they can demonstrate that this will not result in any 
organic HAP emissions increase compared to complying with this subpart.



Sec. 63.5790  What parts of my plant does this subpart cover?

    (a) This subpart applies to each new or existing affected source at 
reinforced plastic composites production facilities.
    (b) The affected source consists of all parts of your facility 
engaged in the following operations: Open molding, closed molding, 
centrifugal casting, continuous lamination, continuous casting, polymer 
casting, pultrusion, sheet molding compound (SMC) manufacturing, bulk 
molding compound (BMC) manufacturing, mixing, cleaning of equipment used 
in reinforced plastic composites manufacture, HAP-containing materials 
storage, and repair operations on parts you also manufacture.
    (c) The following operations are specifically excluded from any 
requirements in this subpart: application of mold sealing and release 
agents; mold stripping and cleaning; repair of parts that you did not 
manufacture, including non-routine manufacturing of parts; personal 
activities that are not part of the manufacturing operations (such as 
hobby shops on military bases); prepreg materials as defined in Sec. 
63.5935; non-gel coat surface coatings; application of putties, 
polyputties, and adhesives; repair or production materials that do not 
contain resin or gel coat; research and development operations as 
defined in section 112(c)(7) of the CAA; polymer casting; and closed 
molding operations (except for compression/injection molding). Note that 
the exclusion of certain operations from any requirements applies only 
to operations specifically listed in this paragraph. The requirements 
for any co-located operations still apply.
    (d) Production resins that must meet military specifications are 
allowed to meet the organic HAP limit contained in that specification. 
In order for this exemption to be used, you must supply to the 
permitting authority the specifications certified as accurate by the 
military procurement officer, and those specifications must state a 
requirement for a specific resin, or a specific resin HAP content. 
Production resins for which this exemption is used must be applied with 
nonatomizing resin application equipment unless you can demonstrate this 
is infeasible. You must keep a record of the resins for which you are 
using this exemption.

[68 FR 19402, Apr. 21, 2003, as amended at 70 FR 50124, Aug. 25, 2005]



Sec. 63.5795  How do I know if my reinforced plastic composites 
production facility is a new affected source or an existing
affected source?

    (a) A reinforced plastic composites production facility is a new 
affected source if it meets all the criteria in paragraphs (a)(1) and 
(2) of this section.
    (1) You commence construction of the source after August 2, 2001.
    (2) You commence construction, and no other reinforced plastic 
composites production source exists at that site.

[[Page 971]]

    (b) For the purposes of this subpart, an existing affected source is 
any affected source that is not a new affected source.

     Calculating Organic HAP Emissions Factors for Open Molding and 
                           Centrifugal Casting



Sec. 63.5796  What are the organic HAP emissions factor equations
in Table 1 to this subpart, and how are they used in this subpart?

    Emissions factors are used in this subpart to determine compliance 
with certain organic HAP emissions limits in Tables 3 and 5 to this 
subpart. You may use the equations in Table 1 to this subpart to 
calculate your emissions factors. Equations are available for each open 
molding operation and centrifugal casting operation and have units of 
pounds of organic HAP emitted per ton (lb/ton) of resin or gel coat 
applied. These equations are intended to provide a method for you to 
demonstrate compliance without the need to conduct for a HAP emissions 
test. In lieu of these equations, you can elect to use site-specific 
organic HAP emissions factors to demonstrate compliance provided your 
site-specific organic HAP emissions factors are incorporated in the 
facility's air emissions permit and are based on actual facility HAP 
emissions test data. You may also use the organic HAP emissions factors 
calculated using the equations in Table 1 to this subpart, combined with 
resin and gel coat use data, to calculate your organic HAP emissions.



Sec. 63.5797  How do I determine the organic HAP content of my
resins and gel coats?

    In order to determine the organic HAP content of resins and gel 
coats, you may rely on information provided by the material 
manufacturer, such as manufacturer's formulation data and material 
safety data sheets (MSDS), using the procedures specified in paragraphs 
(a) through (c) of this section, as applicable.
    (a) Include in the organic HAP total each organic HAP that is 
present at 0.1 percent by mass or more for Occupational Safety and 
Health Administration-defined carcinogens, as specified in 29 CFR 
1910.1200(d)(4) and at 1.0 percent by mass or more for other organic HAP 
compounds.
    (b) If the organic HAP content is provided by the material supplier 
or manufacturer as a range, you must use the upper limit of the range 
for determining compliance. If a separate measurement of the total 
organic HAP content, such as an analysis of the material by EPA Method 
311 of appendix A to 40 CFR part 63, exceeds the upper limit of the 
range of the total organic HAP content provided by the material supplier 
or manufacturer, then you must use the measured organic HAP content to 
determine compliance.
    (c) If the organic HAP content is provided as a single value, you 
may use that value to determine compliance. If a separate measurement of 
the total organic HAP content is made and is less than 2 percentage 
points higher than the value for total organic HAP content provided by 
the material supplier or manufacturer, then you still may use the 
provided value to demonstrate compliance. If the measured total organic 
HAP content exceeds the provided value by 2 percentage points or more, 
then you must use the measured organic HAP content to determine 
compliance.



Sec. 63.5798  What if I want to use, or I manufacture, an application
technology (new or existing) whose organic HAP emissions
characteristics are not represented by the equations in 
Table 1 to this subpart?

    If you wish to use a resin or gel coat application technology (new 
or existing), whose emission characteristics are not represented by the 
equations in Table 1 to this subpart, you may use the procedures in 
paragraphs (a) or (b) of this section to establish an organic HAP 
emissions factor. This organic HAP emissions factor may then be used to 
determine compliance with the emission limits in this subpart, and to 
calculate facility organic HAP emissions.
    (a) Perform an organic HAP emissions test to determine a site-
specific organic HAP emissions factor using the test procedures in Sec. 
63.5850.

[[Page 972]]

    (b) Submit a petition to the Administrator for administrative review 
of this subpart. This petition must contain a description of the resin 
or gel coat application technology and supporting organic HAP emissions 
test data obtained using EPA test methods or their equivalent. The 
emission test data should be obtained using a range of resin or gel coat 
HAP contents to demonstrate the effectiveness of the technology under 
the different conditions, and to demonstrate that the technology will be 
effective at different sites. We will review the submitted data, and, if 
appropriate, update the equations in Table 1 to this subpart.



Sec. 63.5799  How do I calculate my facility's organic HAP emissions
on a tpy basis for purposes of determining which paragraphs of
Sec. 63.5805 apply?

    To calculate your facility's organic HAP emissions in tpy for 
purposes of determining which paragraphs in Sec. 63.5805 apply to you, 
you must use the procedures in either paragraph (a) of this section for 
new facilities prior to startup, or paragraph (b) of this section for 
existing facilities and new facilities after startup. You are not 
required to calculate or report emissions under this section if you are 
an existing facility that does not have centrifugal casting or 
continuous lamination/casting operations, or a new facility that does 
not have any of the following operations: Open molding, centrifugal 
casting, continuous lamination/casting, pultrusion, SMC and BMC 
manufacturing, and mixing. Emissions calculation and emission reporting 
procedures in other sections of this subpart still apply. Calculate 
organic HAP emissions prior to any add-on control device, and do not 
include organic HAP emissions from any resin or gel coat used in 
operations subject to the Boat Manufacturing NESHAP, 40 CFR part 63, 
subpart VVVV, or from the manufacture of large parts as defined in Sec. 
63.5805(d)(2). For centrifugal casting operations at existing 
facilities, do not include any organic HAP emissions where resin or gel 
coat is applied to an open centrifugal mold using open molding 
application techniques. Table 1 and the Table 1 footnotes to this 
subpart present more information on calculating centrifugal casting 
organic HAP emissions. The timing and reporting of these calculations is 
discussed in paragraph (c) of this section.
    (a) For new facilities prior to startup, calculate a weighted 
average organic HAP emissions factor for the operations specified in 
Sec. 63.5805(c) and (d) on a lbs/ton of resin and gel coat basis. Base 
the weighted average on your projected operation for the 12 months 
subsequent to facility startup. Multiply the weighted average organic 
HAP emissions factor by projected resin use over the same period. You 
may calculate your organic HAP emissions factor based on the factors in 
Table 1 to this subpart, or you may use any HAP emissions factor 
approved by us, such as factors from the ``Compilation of Air Pollutant 
Emissions Factors, Volume I: Stationary Point and Area Sources (AP-
42),'' or organic HAP emissions test data from similar facilities.
    (b) For existing facilities and new facilities after startup, you 
may use the procedures in either paragraph (b)(1) or (2) of this 
section. If the emission factors for an existing facility have changed 
over the period of time prior to their initial compliance date due to 
incorporation of pollution-prevention control techniques, existing 
facilities may base the average emission factor on their operations as 
they exist on the compliance date. If an existing facility has accepted 
an enforceable permit limit that would result in less than 100 tpy of 
HAP measured prior to any add-on controls, and can demonstrate that they 
will operate at that level subsequent to the compliance date, they can 
be deemed to be below the 100 tpy threshold.
    (1) Use a calculated emission factor. Calculate a weighted average 
organic HAP emissions factor on a lbs/ton of resin and gel coat basis. 
Base the weighted average on the prior 12 months of operation. Multiply 
the weighted average organic HAP emissions factor by resin and gel coat 
use over the same period. You may calculate this organic HAP emissions 
factor based on the equations in Table 1 to this subpart, or you may use 
any organic HAP emissions factor approved by us, such as factors from 
AP-42, or site-specific organic HAP emissions

[[Page 973]]

factors if they are supported by HAP emissions test data.
    (2) Conduct performance testing. Conduct performance testing using 
the test procedures in Sec. 63.5850 to determine a site-specific 
organic HAP emissions factor in units of lbs/ton of resin and gel coat 
used. Conduct the test under conditions expected to result in the 
highest possible organic HAP emissions. Multiply this factor by annual 
resin and gel coat use to determine annual organic HAP emissions. This 
calculation must be repeated and reported annually.
    (c) Existing facilities must initially perform this calculation 
based on their 12 months of operation prior to April 21, 2003, and 
include this information with their initial notification report. 
Existing facilities must repeat the calculation based on their resin and 
gel coat use in the 12 months prior to their initial compliance date, 
and submit this information with their initial compliance report. After 
their initial compliance date, existing and new facilities must 
recalculate organic HAP emissions over the 12-month period ending June 
30 or December 31, whichever date is the first date following their 
compliance date specified in Sec. 63.5800. Subsequent calculations 
should cover the periods in the semiannual compliance reports.

                     Compliance Dates and Standards



Sec. 63.5800  When do I have to comply with this subpart?

    You must comply with the standards in this subpart by the dates 
specified in Table 2 to this subpart. Facilities meeting an organic HAP 
emissions standard based on a 12-month rolling average must begin 
collecting data on the compliance date in order to demonstrate 
compliance.



Sec. 63.5805  What standards must I meet to comply with this subpart?

    You must meet the requirements of paragraphs (a) through (h) of this 
section that apply to you. You may elect to comply using any options to 
meet the standards described in Sec. Sec. 63.5810 through 63.5830. Use 
the procedures in Sec. 63.5799 to determine if you meet or exceed the 
100 tpy threshold.
    (a) If you have an existing facility that has any centrifugal 
casting or continuous casting/lamination operations, you must meet the 
requirements of paragraph (a)(1) or (2) of this section:
    (1) If the combination of all centrifugal casting and continuous 
lamination/casting operations emit 100 tpy or more of HAP, you must 
reduce the total organic HAP emissions from centrifugal casting and 
continuous lamination/casting operations by at least 95 percent by 
weight. As an alternative to meeting the 95 percent by weight 
requirement, centrifugal casting operations may meet the applicable 
organic HAP emissions limits in Table 5 to this subpart and continuous 
lamination/casting operations may meet an organic HAP emissions limit of 
1.47 lbs/ton of neat resin plus and neat gel coat plus applied. For 
centrifugal casting, the percent reduction requirement does not apply to 
organic HAP emissions that occur during resin application onto an open 
centrifugal casting mold using open molding application techniques.
    (2) If the combination of all centrifugal casting and continuous 
lamination/casting operations emit less than 100 tpy of HAP, then 
centrifugal casting and continuous lamination/casting operations must 
meet the appropriate requirements in Table 3 to this subpart.
    (b) All operations at existing facilities not listed in paragraph 
(a) of this section must meet the organic HAP emissions limits in Table 
3 to this subpart and the work practice standards in Table 4 to this 
subpart that apply, regardless of the quantity of HAP emitted.
    (c) If you have a new facility that emits less than 100 tpy of HAP 
from the combination of all open molding, centrifugal casting, 
continuous lamination/casting, pultrusion, SMC manufacturing, mixing, 
and BMC manufacturing, you must meet the organic HAP emissions limits in 
Table 3 to this subpart and the work practice standards in Table 4 to 
this subpart that apply to you.

[[Page 974]]

    (d)(1) Except as provided in paragraph (d)(2) of this section, if 
you have a new facility that emits 100 tpy or more of HAP from the 
combination of all open molding, centrifugal casting, continuous 
lamination/casting, pultrusion, SMC manufacturing, mixing, and BMC 
manufacturing, you must reduce the total organic HAP emissions from 
these operations by at least 95 percent by weight and meet any 
applicable work practice standards in Table 4 to this subpart that apply 
to you. As an alternative to meeting 95 percent by weight, you may meet 
the organic HAP emissions limits in Table 5 to this subpart. If you have 
a continuous lamination/casting operation, that operation may 
alternatively meet an organic HAP emissions limit of 1.47 lbs/ton of 
neat resin plus and neat gel coat plus applied.
    (2)(i) If your new facility manufactures large reinforced plastic 
composites parts using open molding or pultrusion operations, the 
specific open molding and pultrusion operations used to produce large 
parts are not required to reduce HAP emissions by 95 weight percent, but 
must meet the emission limits in Table 3 to this subpart.
    (ii) A large open molding part is defined as a part that, when the 
final finished part is enclosed in the smallest rectangular six-sided 
box into which the part can fit, the total interior volume of the box 
exceeds 250 cubic feet, or any interior sides of the box exceed 50 
square feet.
    (iii) A large pultruded part is a part that exceeds an outside 
perimeter of 24 inches or has more than 350 reinforcements.
    (e) If you have a new or existing facility subject to paragraph 
(a)(2) or (c) of this section at its initial compliance date that 
subsequently meets or exceeds the 100 tpy threshold in any calendar 
year, you must notify your permitting authority in your compliance 
report. You may at the same time request a one-time exemption from the 
requirements of paragraph (a)(1) or (d) of this section in your 
compliance report if you can demonstrate all of the following:
    (1) The exceedance of the threshold was due to circumstances that 
will not be repeated.
    (2) The average annual organic HAP emissions from the potentially 
affected operations for the last 3 years were below 100 tpy.
    (3) Projected organic HAP emissions for the next calendar year are 
below 100 tpy, based on projected resin and gel coat use and the HAP 
emission factors calculated according to the procedures in Sec. 
63.5799.
    (f) If you apply for an exemption in paragraph (e) of this section 
and subsequently exceed the HAP emission thresholds specified in 
paragraph (a)(2) or (c) of this section over the next 12-month period, 
you must notify the permitting authority in your semiannual report, the 
exemption is removed, and your facility must comply with paragraph 
(a)(1) or (d) of this section within 3 years from the time your organic 
HAP emissions first exceeded the threshold.
    (g) If you have repair operations subject to this subpart as defined 
in Sec. 63.5785, these repair operations must meet the requirements in 
Tables 3 and 4 to this subpart and are not required to meet the 95 
percent organic HAP emissions reduction requirements in paragraph (a)(1) 
or (d) of this section.
    (h) If you use an add-on control device to comply with this subpart, 
you must meet all requirements contained in 40 CFR part 63, subpart SS.

[70 FR 50124, Aug. 25, 2005]

                      Options for Meeting Standards



Sec. 63.5810  What are my options for meeting the standards for open
molding and centrifugal casting operations at new and existing sources?

    You must use one of the following methods in paragraphs (a) through 
(d) of this section to meet the standards for open molding or 
centrifugal casting operations in Table 3 or 5 to this subpart. You may 
use any control method that reduces organic HAP emissions, including 
reducing resin and gel coat organic HAP content, changing to nonatomized 
mechanical application, using covered curing techniques, and routing 
part or all of your emissions to an add-on control. You may use 
different compliance options for the different operations listed in 
Table 3 or 5

[[Page 975]]

to this subpart. The necessary calculations must be completed within 30 
days after the end of each month. You may switch between the compliance 
options in paragraphs (a) through (d) of this section. When you change 
to an option based on a 12-month rolling average, you must base the 
average on the previous 12 months of data calculated using the 
compliance option you are changing to, unless you were previously using 
an option that did not require you to maintain records of resin and gel 
coat use. In this case, you must immediately begin collecting resin and 
gel coat use data and demonstrate compliance 12 months after changing 
options.
    (a) Demonstrate that an individual resin or gel coat, as applied, 
meets the applicable emission limit in Table 3 or 5 to this subpart. (1) 
Calculate your actual organic HAP emissions factor for each different 
process stream within each operation type. A process stream is defined 
as each individual combination of resin or gel coat, application 
technique, and control technique. Process streams within operations 
types are considered different from each other if any of the following 
four characteristics vary: the neat resin plus or neat gel coat plus 
organic HAP content, the gel coat type, the application technique, or 
the control technique. You must calculate organic HAP emissions factors 
for each different process stream by using the appropriate equations in 
Table 1 to this subpart for open molding and for centrifugal casting, or 
site-specific organic HAP emissions factors discussed in Sec. 63.5796. 
The emission factor calculation should include any and all emission 
reduction techniques used including any add-on controls. If you are 
using vapor suppressants to reduce HAP emissions, you must determine the 
vapor suppressant effectiveness (VSE) by conducting testing according to 
the procedures specified in appendix A to subpart WWWW of 40 CFR part 
63. If you are using an add-on control device to reduce HAP emissions, 
you must determine the add-on control factor by conducting capture and 
control efficiency testing using the procedures specified in Sec. 
63.5850. The organic HAP emissions factor calculated from the equations 
in Table 1 to this subpart, or a site-specific emissions factor, is 
multiplied by the add-on control factor to calculate the organic HAP 
emissions factor after control. Use Equation 1 of this section to 
calculate the add-on control factor used in the organic HAP emissions 
factor equations.

Where:
Percent Control Efficiency=a value calculated from organic HAP emissions 
          test measurements made according to the requirements of Sec. 
          63.5850 to this subpart.

    (2) If the calculated emission factor is less than or equal to the 
appropriate emission limit, you have demonstrated that this process 
stream complies with the emission limit in Table 3 to this subpart. It 
is not necessary that all your process streams, considered individually, 
demonstrate compliance to use this option for some process streams. 
However, for any individual resin or gel coat you use, if any of the 
process streams that include that resin or gel coat are to be used in 
any averaging calculations described in paragraphs (b) through (d) of 
this section, then all process streams using that individual resin or 
gel coat must be included in the averaging calculations.
    (b) Demonstrate that, on average, you meet the individual organic 
HAP emissions limits for each combination of operation type and resin 
application method or gel coat type. Demonstrate that on average you 
meet the individual organic HAP emissions limits for each unique 
combination of operation type and resin application method or gel coat 
type shown in Table 3 to this subpart that applies to you.
    (1)(i) Group the process streams described in paragraph (a) to this 
section

[[Page 976]]

by operation type and resin application method or gel coat type listed 
in Table 3 to this subpart and then calculate a weighted average 
emission factor based on the amounts of each individual resin or gel 
coat used for the last 12 months. To do this, sum the product of each 
individual organic HAP emissions factor calculated in paragraph (a)(1) 
of this section and the amount of neat resin plus and neat gel coat plus 
usage that corresponds to the individual factors and divide the 
numerator by the total amount of neat resin plus and neat gel coat plus 
used in that operation type as shown in Equation 2 of this section.
[GRAPHIC] [TIFF OMITTED] TR25AU05.014

Where:
Actual Process Stream EFi = actual organic HAP emissions 
          factor for process stream i, lbs/ton;
Materiali = neat resin plus or neat gel coat plus used during 
          the last 12 calendar months for process stream i, tons;
n=number of process streams where you calculated an organic HAP 
          emissions factor.

    (ii) You may, but are not required to, include process streams where 
you have demonstrated compliance as described in paragraph (a) of this 
section, subject to the limitations described in paragraph (a)(2) of 
this section, and you are not required to and should not include process 
streams for which you will demonstrate compliance using the procedures 
in paragraph (d) of this section.
    (2) Compare each organic HAP emissions factor calculated in 
paragraph (b)(1) of this section with its corresponding organic HAP 
emissions limit in Table 3 or 5 to this subpart. If all emissions 
factors are equal to or less than their corresponding emission limits, 
then you are in compliance.
    (c) Demonstrate compliance with a weighted average emission limit. 
Demonstrate each month that you meet each weighted average of the 
organic HAP emissions limits in Table 3 or 5 to this subpart that apply 
to you. When using this option, you must demonstrate compliance with the 
weighted average organic HAP emissions limit for all your open molding 
operations, and then separately demonstrate compliance with the weighted 
average organic HAP emissions limit for all your centrifugal casting 
operations. Open molding operations and centrifugal casting operations 
may not be averaged with each other.
    (1) Each month calculate the weighted average organic HAP emissions 
limit for all open molding operations and the weighted average organic 
HAP emissions limit for all centrifugal casting operations for your 
facility for the last 12-month period to determine the organic HAP 
emissions limit you must meet. To do this, multiply the individual 
organic HAP emissions limits in Table 3 or 5 to this subpart for each 
open molding (centrifugal casting) operation type by the amount of neat 
resin plus or neat gel coat plus used in the last 12 months for each 
open molding (centrifugal casting) operation type, sum these results, 
and then divide this sum by the total amount of neat resin plus and neat 
gel coat plus used in open molding (centrifugal casting) over the last 
12 months as shown in Equation 3 of this section.

Where:
ELi = organic HAP emissions limit for operation type i, lbs/
          ton from Tables 3 or 5 to this subpart;
Materiali = neat resin plus or neat gel coat plus used during 
          the last 12-month period for operation type i, tons;
n=number of operations.

    (2) Each month calculate your weighted average organic HAP emissions 
factor for open molding and centrifugal casting. To do this, multiply 
your actual open molding (centrifugal casting) operation organic HAP 
emissions factors calculated in paragraph (b)(1) of this section and the 
amount of neat resin plus and neat gel coat plus used in each open 
molding (centrifugal casting) operation type, sum the results, and 
divide this sum by the total amount of neat resin plus and neat gel coat 
plus used in open molding (centrifugal casting) operations as shown in 
Equation 4 of this section.
[GRAPHIC] [TIFF OMITTED] TR25AU05.016

Where:
Actual Individual EFi = Actual organic HAP emissions factor 
          for operation type i, lbs/ton;
Materiali = neat resin plus or neat gel coat plus used during 
          the last 12 calendar months for operation type i, tons;
n=number of operations.

    (3) Compare the values calculated in paragraphs (c)(1) and (2) of 
this section. If each 12-month rolling average organic HAP emissions 
factor is less than or equal to the corresponding 12-month rolling 
average organic HAP emissions limit, then you are in compliance.
    (d) Meet the organic HAP emissions limit for one application method 
and use the same resin(s) for all application methods of that resin 
type. This option is limited to resins of the same type. The resin types 
for which this option may be used are noncorrosion-resistant, corrosion-
resistant and/or high strength, and tooling.
    (1) For any combination of manual resin application, mechanical 
resin application, filament application, or centrifugal casting, you may 
elect to meet the organic HAP emissions limit for any one of these 
application methods and use the same resin in all of the resin 
application methods listed in this paragraph (d)(1). Table 7 to this 
subpart presents the possible combinations based on a facility selecting 
the application process that results in the highest allowable organic 
HAP content resin. If the resin organic HAP content is below the 
applicable value shown in Table 7 to this subpart, the resin is in 
compliance.
    (2) You may also use a weighted average organic HAP content for each 
application method described in paragraph (d)(1) of this section. 
Calculate the weighted average organic HAP content monthly. Use Equation 
2 in paragraph (b)(1) of this section except substitute organic HAP 
content for organic HAP emissions factor. You are in compliance if the 
weighted average organic HAP content based on the last 12 months of 
resin use is less than or

[[Page 978]]

equal to the applicable organic HAP contents in Table 7 to this subpart.
    (3) You may simultaneously use the averaging provisions in paragraph 
(b) or (c) of this section to demonstrate compliance for any operations 
and/or resins you do not include in your compliance demonstrations in 
paragraphs (d)(1) and (2) of this section. However, any resins for which 
you claim compliance under the option in paragraphs (d)(1) and (2) of 
this section may not be included in any of the averaging calculations 
described in paragraph (b) or (c) of this section.
    (4) You do not have to keep records of resin use for any of the 
individual resins where you demonstrate compliance under the option in 
paragraph (d)(1) of this section unless you elect to include that resin 
in the averaging calculations described in paragraph (d)(2) of this 
section.

own, two or more lines averaged together meet the standards, and one or 
more lines have their wet-out areas controlled to a level of 95 
percent).



Sec. 63.5830  What are my options for meeting the standards for
pultrusion operations subject to the 60 weight percent organic
HAP emissions reductions  requirement?

    You must use one or more of the options in paragraphs (a) through 
(e) of this section to meet the 60 weight percent organic HAP emissions 
limit in Table 3 to this subpart, as required in Sec. 63.5805.
    (a) Achieve an overall reduction in organic HAP emissions of 60 
weight percent by capturing the organic HAP emissions and venting them 
to a control device or any combination of control devices. Conduct 
capture and destruction efficiency testing as specified in 63.5850 to 
this subpart to determine the percent organic HAP emissions reduction.
    (b) Design, install, and operate wet area enclosures and resin drip 
collection systems on pultrusion machines that meet the criteria in 
paragraphs (b)(1) through (10) of this section.
    (1) The enclosure must cover and enclose the open resin bath and the 
forming area in which reinforcements are pre-wet or wet-out and moving 
toward the die(s). The surfaces of the enclosure must be closed except 
for openings to allow material to enter and exit the enclosure.
    (2) For open bath pultrusion machines with a radio frequency pre-
heat unit, the enclosure must extend from the beginning of the resin 
bath to within 12.5 inches or less of the entrance of the radio 
frequency pre-heat unit. If the stock that is within 12.5 inches or less 
of the entrance to the radio frequency pre-heat unit has any drip, it 
must be enclosed. The stock exiting the radio frequency pre-heat unit is 
not required to be in an enclosure if the stock has no drip between the 
exit of the radio frequency pre-heat unit to within 0.5 inches of the 
entrance of the die.
    (3) For open bath pultrusion machines without a radio frequency pre-
heat unit, the enclosure must extend from the beginning of the resin 
bath to within 0.5 inches or less of the die entrance.

[[Page 979]]

    (4) For pultrusion lines with pre-wet area(s) prior to direct die 
injection, no more than 12.5 inches of open wet stock is permitted 
between the entrance of the first pre-wet area and the entrance to the 
die. If the pre-wet stock has any drip, it must be enclosed.
    (5) The total open area of the enclosure must not exceed two times 
the cross sectional area of the puller window(s) and must comply with 
the requirements in paragraphs (b)(5)(i) through (iii) of this section.
    (i) All areas that are open need to be included in the total open 
area calculation with the exception of access panels, doors, and/or 
hatches that are part of the enclosure.
    (ii) The area that is displaced by entering reinforcement or exiting 
product is considered open.
    (iii) Areas that are covered by brush covers are considered closed.
    (6) Open areas for level control devices, monitoring devices, 
agitation shafts, and fill hoses must have no more than 1.0 inch 
clearance.
    (7) The access panels, doors, and/or hatches that are part of the 
enclosure must close tightly. Damaged access panels, doors, and/or 
hatches that do not close tightly must be replaced.
    (8) The enclosure may not be removed from the pultrusion line, and 
access panels, doors, and/or hatches that are part of the enclosure must 
remain closed whenever resin is in the bath, except for the time period 
discussed in paragraph (b)(9) of this section.
    (9) The maximum length of time the enclosure may be removed from the 
pultrusion line or the access panels, doors, and/or hatches and may be 
open, is 30 minutes per 8 hour shift, 45 minutes per 12 hour shift, or 
90 minutes per day if the machine is operated for 24 hours in a day. The 
time restrictions do not apply if the open doors or panels do not cause 
the limit of two times the puller window area to be exceeded. Facilities 
may average the times that access panels, doors, and/or hatches are open 
across all operating lines. In that case the average must not exceed the 
times shown in this paragraph (b)(9). All lines included in the average 
must have operated the entire time period being averaged.
    (10) No fans, blowers, and/or air lines may be allowed within the 
enclosure. The enclosure must not be ventilated.
    (c) Use direct die injection pultrusion machines with resin drip 
collection systems that meet all the criteria specified in paragraphs 
(c)(1) through (3) of this section.
    (1) All the resin that is applied to the reinforcement is delivered 
directly to the die.
    (2) No exposed resin is present, except at the face of the die.
    (3) Resin drip is captured in a closed system and recycled back to 
the process.
    (d) Use a preform injection system that meets the definition in 
Sec. 63.5935
    (e) Use any combination of options in paragraphs (a) through (d) of 
this section in which different pultrusion lines comply with different 
options described in paragraphs (a) through (d) of this section, and
    (1) Each individual pultrusion machine meets the 60 percent 
reduction requirement, or
    (2) The weighted average reduction based on resin throughput of all 
machines combined is 60 percent. For purposes of the average percent 
reduction calculation, wet area enclosures reduce organic HAP emissions 
by 60 percent, and direct die injection and preform injection reduce 
organic HAP emissions by 90 percent.

[68 FR 19402, Apr. 21, 2003, as amended at 71 FR 20466, Apr. 20, 2006]

               Testing and Initial Compliance Requirements



Sec. 63.5840  By what date must I conduct a performance test or
other initial compliance demonstration?

    You must conduct performance tests, performance evaluations, design 
evaluations, capture efficiency testing, and other initial compliance 
demonstrations by the compliance date specified in Table 2 to this 
subpart, with three exceptions. Open molding and centrifugal casting 
operations that elect to meet an organic HAP emissions limit on a 12-
month rolling average must initiate collection of the required data on 
the compliance date, and demonstrate compliance 1 year after the 
compliance date. New sources that use add-on controls to initially meet 
compliance must demonstrate compliance within 180 days after their 
compliance date.



Sec. 63.5845  When must I conduct subsequent performance tests?

    You must conduct a performance test every 5 years following the 
initial performance test for any standard you meet with an add-on 
control device.



Sec. 63.5850  How do I conduct performance tests, performance
evaluations, and design evaluations?

    (a) If you are using any add-on controls to meet an organic HAP 
emissions limit in this subpart, you must conduct each performance test, 
performance evaluation, and design evaluation in 40 CFR part 63, subpart 
SS, that applies to you. The basic requirements for performance tests, 
performance evaluations, and design evaluations are presented in Table 6 
to this subpart.
    (b) Each performance test must be conducted according to the 
requirements in Sec. 63.7(e)(1) and under the specific conditions that 
40 CFR part 63, subpart SS, specifies.
    (c) Each performance evaluation must be conducted according to the 
requirements in Sec. 63.8(e) as applicable and under the specific 
conditions that 40 CFR part 63, subpart SS, specifies.
    (d) You may not conduct performance tests or performance evaluations 
during periods of startup, shutdown, or malfunction, as specified in 
Sec. 63.7(e)(1).
    (e) You must conduct the control device performance test using the 
emission measurement methods specified in paragraphs (e)(1) through (5) 
of this section.
    (1) Use either Method 1 or 1A of appendix A to 40 CFR part 60, as 
appropriate, to select the sampling sites.
    (2) Use Method 2, 2A, 2C, 2D, 2F or 2G of appendix A to 40 CFR part 
60, as appropriate, to measure gas volumetric flow rate.
    (3) Use Method 18 of appendix A to 40 CFR part 60 to measure organic 
HAP emissions or use Method 25A of appendix A to 40 CFR part 60 to 
measure total gaseous organic emissions as a surrogate for total organic 
HAP emissions. If you use Method 25A, you must assume that all gaseous 
organic emissions measured as carbon are organic HAP emissions. If you 
use Method 18 and the number of organic HAP in the exhaust stream 
exceeds five, you must take into account the use of multiple 
chromatographic columns and analytical techniques to get an accurate 
measure of at least 90 percent of the total organic HAP mass emissions. 
Do not use Method 18 to measure organic HAP emissions from a combustion 
device; use instead Method 25A and assume that all gaseous organic mass 
emissions measured as carbon are organic HAP emissions.
    (4) You may use American Society for Testing and Materials (ASTM) 
D6420-99 (available for purchase from at least one of the following 
addresses: 100 Barr Harbor Drive, West Conshohocken, PA 19428-2959; or 
University Microfilms International, 300 North Zeeb Road, Ann Arbor, MI 
48106.) in lieu of Method 18 of 40 CFR part 60,

[[Page 981]]

appendix A, under the conditions specified in paragraphs (c)(4)(i) 
through (iii) of this section.
    (i) If the target compound(s) is listed in Section 1.1 of ASTM 
D6420-99 and the target concentration is between 150 parts per billion 
by volume and 100 parts per million by volume.
    (ii) If the target compound(s) is not listed in Section 1.1 of ASTM 
D6420-99, but is potentially detected by mass spectrometry, an 
additional system continuing calibration check after each run, as 
detailed in Section 10.5.3 of ASTM D6420-99, must be followed, met, 
documented, and submitted with the performance test report even if you 
do not use a moisture condenser or the compound is not considered 
soluble.
    (iii) If a minimum of one sample/analysis cycle is completed at 
least every 15 minutes.
    (5) Use the procedures in EPA Method 3B of appendix A to 40 CFR part 
60 to determine an oxygen correction factor if required by Sec. 
63.997(e)(2)(iii)(C). You may use American Society of Mechanical 
Engineers (ASME) PTC 19-10-1981-Part 10 (available for purchase from 
ASME, P.O. Box 2900, 22 Law Drive, Fairfield, New Jersey, 07007-2900, or 
online at www.asme.org/catalog) as an alternative to EPA Method 3B of 
appendix A to 40 CFR part 60.
    (f) The control device performance test must consist of three runs 
and each run must last at least 1 hour. The production conditions during 
the test runs must represent normal production conditions with respect 
to the types of parts being made and material application methods. The 
production conditions during the test must also represent maximum 
potential emissions with respect to the organic HAP content of the 
materials being applied and the material application rates.
    (g) If you are using a concentrator/oxidizer control device, you 
must test the combined flow upstream of the concentrator, and the 
combined outlet flow from both the oxidizer and the concentrator to 
determine the overall control device efficiency. If the outlet flow from 
the concentrator and oxidizer are exhausted in separate stacks, you must 
test both stacks simultaneously with the inlet to the concentrator to 
determine the overall control device efficiency.
    (h) During the test, you must also monitor and record separately the 
amounts of production resin, tooling resin, pigmented gel coat, clear 
gel coat, and tooling gel coat applied inside the enclosure that is 
vented to the control device.



Sec. 63.5855  What are my monitor installation and operation
requirements?

    You must monitor and operate all add-on control devices according to 
the procedures in 40 CFR part 63, subpart SS.



Sec. 63.5860  How do I demonstrate initial compliance with the standards?

    (a) You demonstrate initial compliance with each organic HAP 
emissions standard in paragraphs (a) through (h) of Sec. 63.5805 that 
applies to you by using the procedures shown in Tables 8 and 9 to this 
subpart.
    (b) If using an add-on control device to demonstrate compliance, you 
must also establish each control device operating limit in 40 CFR part 
63, subpart SS, that applies to you.

 Emission Factor, Percent Reduction, and Capture Efficiency Calculation 
         Procedures for Continuous Lamination/Casting Operations



Sec. 63.5865  What data must I generate to demonstrate compliance 
with the standards for continuous lamination/casting operations?

    (a) For continuous lamination/casting affected sources complying 
with a percent reduction requirement, you must generate the data 
identified in Tables 10 and 11 to this subpart for each data requirement 
that applies to your facility.
    (b) For continuous lamination/casting affected sources complying 
with a lbs/ton limit, you must generate the data identified in Tables 11 
and 12 to this subpart for each data requirement that applies to your 
facility.

[[Page 982]]



Sec. 63.5870  How do I calculate annual uncontrolled and controlled
organic HAP emissions from my wet-out area(s) and from my oven(s)
for continuous lamination/casting operations?

    To calculate your annual uncontrolled and controlled organic HAP 
emissions from your wet-out areas and from your ovens, you must develop 
uncontrolled and controlled wet-out area and uncontrolled and controlled 
oven organic HAP emissions estimation equations or factors to apply to 
each formula applied on each line, determine how much of each formula 
for each end product is applied each year on each line, and assign 
uncontrolled and controlled wet-out area and uncontrolled and controlled 
oven organic HAP emissions estimation equations or factors to each 
formula. You must determine the overall capture efficiency using the 
procedures in Sec. 63.5850 to this subpart.
    (a) To develop uncontrolled and controlled organic HAP emissions 
estimation equations and factors, you must, at a minimum, do the 
following, as specified in paragraphs (a)(1) through (6) of this 
section:
    (1) Identify each end product and the thickness of each end product 
produced on the line. Separate end products into the following end 
product groupings, as applicable: corrosion-resistant gel coated end 
products, noncorrosion-resistant gel coated end products, corrosion-
resistant nongel coated end products, and noncorrosion-resistant nongel 
coated end products. This step creates end product/thickness 
combinations.
    (2) Identify each formula used on the line to produce each end 
product/thickness combination. Identify the amount of each such formula 
applied per year. Rank each formula used to produce each end product/
thickness combination according to usage within each end product/
thickness combination.
    (3) For each end product/thickness combination being produced, 
select the formula with the highest usage rate for testing.
    (4) If not already selected, also select the worst-case formula 
(likely to be associated with the formula with the highest organic HAP 
content, type of HAP, application of gel coat, thin product, low line 
speed, higher resin table temperature) amongst all formulae. (You may 
use the results of the worst-case formula test for all formulae if 
desired to limit the amount of testing required.)
    (5) For each formula selected for testing, conduct at least one test 
(consisting of three runs). During the test, track information on 
organic HAP content and type of HAP, end product thickness, line speed, 
and resin temperature on the wet-out area table.
    (6) Using the test results, develop uncontrolled and controlled 
organic HAP emissions estimation equations (or factors) or series of 
equations (or factors) that best fit the results for estimating 
uncontrolled and controlled organic HAP emissions, taking into account 
the organic HAP content and type of HAP, end product thickness, line 
speed, and resin temperature on the wet-out area table.
    (b) In lieu of using the method specified in paragraph (a) of this 
section for developing uncontrolled and controlled organic HAP emissions 
estimation equations and factors, you may either method specified in 
paragraphs (b)(1) and (2) of this section, as applicable.
    (1) For either uncontrolled or controlled organic HAP emissions 
estimates, you may use previously established, facility-specific organic 
HAP emissions equations or factors, provided they allow estimation of 
both wet-out area and oven organic HAP emissions, where necessary, and 
have been approved by your permitting authority. If a previously 
established equation or factor is specific to the wet-out area only, or 
to the oven only, then you must develop the corresponding uncontrolled 
or controlled equation or factor for the other organic HAP emissions 
source.
    (2) For uncontrolled (controlled) organic HAP emissions estimates, 
you may use controlled (uncontrolled) organic HAP emissions estimates 
and control device destruction efficiency to calculate your uncontrolled 
(controlled) organic HAP emissions provided the control device 
destruction efficiency was calculated at the same time you collected the 
data to develop

[[Page 983]]

your facility's controlled (uncontrolled) organic HAP emissions 
estimation equations and factors.
    (c) Assign to each formula an uncontrolled organic HAP emissions 
estimation equation or factor based on the end product/thickness 
combination for which that formula is used.
    (d)(1) To calculate your annual uncontrolled organic HAP emissions 
from wet-out areas that do not have any capture and control and from 
wet-out areas that are captured by an enclosure but are vented to the 
atmosphere and not to a control device, multiply each formula's annual 
usage by its appropriate organic HAP emissions estimation equation or 
factor and sum the individual results.
    (2) To calculate your annual uncontrolled organic HAP emissions that 
escape from the enclosure on the wet-out area, multiply each formula's 
annual usage by its appropriate uncontrolled organic HAP emissions 
estimation equation or factor, sum the individual results, and multiply 
the summation by 1 minus the percent capture (expressed as a fraction).
    (3) To calculate your annual uncontrolled oven organic HAP 
emissions, multiply each formula's annual usage by its appropriate 
uncontrolled organic HAP emissions estimation equation or factor and sum 
the individual results.
    (4) To calculate your annual controlled organic HAP emissions, 
multiply each formula's annual usage by its appropriate organic HAP 
emissions estimation equation or factor and sum the individual results 
to obtain total annual controlled organic HAP emissions.
    (e) Where a facility is calculating both uncontrolled and controlled 
organic HAP emissions estimation equations and factors, you must test 
the same formulae. In addition, you must develop both sets of equations 
and factors from the same tests.



Sec. 63.5875  How do I determine the capture efficiency of the enclosure
on my wet-out area and the capture efficiency of my oven(s) for
continuous lamination/casting operations?

    (a) The capture efficiency of a wet-out area enclosure is assumed to 
be 100 percent if it meets the design and operation requirements for a 
permanent total enclosure (PTE) specified in EPA Method 204 of appendix 
M to 40 CFR part 51. If a PTE does not exist, then a temporary total 
enclosure must be constructed and verified using EPA Method 204, and 
capture efficiency testing must be determined using EPA Methods 204B 
through E of appendix M to 40 CFR part 51.
    (b) The capture efficiency of an oven is to be considered 100 
percent, provided the oven is operated under negative pressure.



Sec. 63.5880  How do I determine how much neat resin plus is applied
to the line and how much neat gel coat plus is applied to the line 
for continuous lamination/casting operations?

    Use the following procedures to determine how much neat resin plus 
and neat gel coat plus is applied to the line each year.
    (a) Track formula usage by end product/thickness combinations.
    (b) Use in-house records to show usage. This may be either from 
automated systems or manual records.
    (c) Record daily the usage of each formula/end product combination 
on each line. This is to be recorded at the end of each run (i.e., when 
a changeover in formula or product is made) and at the end of each 
shift.
    (d) Sum the amounts from the daily records to calculate annual usage 
of each formula/end product combination by line.



Sec. 63.5885  How do I calculate percent reduction to demonstrate
compliance for continuous lamination/casting operations?

    You may calculate percent reduction using any of the methods in 
paragraphs (a) through (d) of this section.
    (a) Compliant line option. If all of your wet-out areas have PTE 
that meet the requirements of EPA Method 204 of appendix M of 40 CFR 
part 51, and all of your wet-out area organic HAP emissions and oven 
organic HAP emissions are vented to an add-on control device, use 
Equation 1 of this section to demonstrate compliance. In all other 
situations, use Equation 2 of this section to demonstrate compliance.

                   Continuous Compliance Requirements



Sec. 63.5895  How do I monitor and collect data to demonstrate 
continuous compliance?

    (a) During production, you must collect and keep a record of data as 
indicated in 40 CFR part 63, subpart SS, if you are using an add-on 
control device.
    (b) You must monitor and collect data as specified in paragraphs 
(b)(1) through (4) of this section.
    (1) Except for monitoring malfunctions, associated repairs, and 
required quality assurance or control activities (including, as 
applicable, calibration checks and required zero and span adjustments), 
you must conduct all monitoring in continuous operation (or collect data 
at all required intervals) at all times that the affected source is 
operating.
    (2) You may not use data recorded during monitoring malfunctions, 
associated repairs, and required quality assurance or control activities 
for purposes to this subpart, including data averages and calculations, 
or fulfilling a minimum data availability requirement, if applicable. 
You must use all the data collected during all other periods in 
assessing the operation of the control device and associated control 
system.
    (3) At all times, you must maintain necessary parts for routine 
repairs of the monitoring equipment.
    (4) A monitoring malfunction is any sudden, infrequent, not 
reasonably preventable failure of the monitoring equipment to provide 
valid data. Monitoring failures that are caused in part by poor 
maintenance or careless operation are not malfunctions.
    (c) You must collect and keep records of resin and gel coat use, 
organic HAP content, and operation where the resin is used if you are 
meeting any organic HAP emissions limits based on an organic HAP 
emissions limit in Tables 3 or 5 to this subpart. You must collect and 
keep records of resin and gel coat

[[Page 986]]

use, organic HAP content, and operation where the resin is used if you 
are meeting any organic HAP content limits in Table 7 to this subpart if 
you are averaging organic HAP contents. Resin use records may be based 
on purchase records if you can reasonably estimate how the resin is 
applied. The organic HAP content records may be based on MSDS or on 
resin specifications supplied by the resin supplier.
    (d) Resin and gel coat use records are not required for the 
individual resins and gel coats that are demonstrated, as applied, to 
meet their applicable emission as defined in Sec. 63.5810(a). However, 
you must retain the records of resin and gel coat organic HAP content, 
and you must include the list of these resins and gel coats and identify 
their application methods in your semiannual compliance reports. If 
after you have initially demonstrated that a specific combination of an 
individual resin or gel coat, application method, and controls meets its 
applicable emission limit, and the resin or gel coat changes or the 
organic HAP content increases, or you change the application method or 
controls, then you again must demonstrate that the individual resin or 
gel coat meets its emission limit as specified in paragraph (a) of Sec. 
63.5810. If any of the previously mentioned changes results in a 
situation where an individual resin or gel coat now exceeds its 
applicable emission limit in Table 3 or 5 of this subpart, you must 
begin collecting resin and gel coat use records and calculate compliance 
using one of the averaging options on a 12-month rolling average.
    (e) For each of your pultrusion machines, you must record all times 
that wet area enclosures doors or covers are open and there is resin 
present in the resin bath.

Sec. 63.5900  How do I demonstrate continuous compliance with the 
standards?

    (a) You must demonstrate continuous compliance with each standard in 
Sec. 63.5805 that applies to you according to the methods specified in 
paragraphs (a)(1) through (3) of this section.
    (1) Compliance with organic HAP emissions limits for sources using 
add-on control devices is demonstrated following the procedures in 40 
CFR part 63, subpart SS. Sources using add-on controls may also use 
continuous emissions monitors to demonstrate continuous compliance as an 
alternative to control parameter monitoring.
    (2) Compliance with organic HAP emissions limits is demonstrated by 
maintaining an organic HAP emissions factor value less than or equal to 
the appropriate organic HAP emissions limit listed in Table 3 or 5 to 
this subpart, on a 12-month rolling average, and/or by including in each 
compliance report a statement that individual resins and gel coats, as 
applied, meet the appropriate organic HAP emissions limits, as discussed 
in Sec. 63.5895(d).
    (3) Compliance with organic HAP content limits in Table 7 to this 
subpart is demonstrated by maintaining an average organic HAP content 
value less than or equal to the appropriate organic HAP contents listed 
in Table 7 to this subpart, on a 12-month rolling average, and/or by 
including in each compliance report a statement that resins and gel 
coats individually meet the appropriate organic HAP content limits in 
Table 7 to this subpart, as discussed in Sec. 63.5895(d).
    (4) Compliance with the work practice standards in Table 4 to this 
subpart is demonstrated by performing the work practice required for 
your operation.
    (b) You must report each deviation from each standard in Sec. 
63.5805 that applies to you. The deviations must be reported according 
to the requirements in Sec. 63.5910.
    (c) Except as provided in paragraph (d) of this section, during 
periods of startup, shutdown or malfunction, you must meet the organic 
HAP emissions limits and work practice standards that apply to you.
    (d) When you use an add-on control device to meet standards in Sec. 
63.5805, you are not required to meet those standards during periods of 
startup, shutdown, or malfunction, but you must operate your affected 
source to minimize emissions in accordance with Sec. 63.6(e)(1).

[[Page 987]]

    (e) Consistent with Sec. Sec. 63.6(e) and 63.7(e)(1), deviations 
that occur during a period of malfunction for those affected sources and 
standards specified in paragraph (d) of this section are not violations 
if you demonstrate to the Administrator's satisfaction that you were 
operating in accordance with Sec. 63.6(e)(1). The Administrator will 
determine whether deviations that occur during a period of startup, 
shutdown, and malfunction are violations, according to the provisions in 
Sec. 63.6(e).

and in this section as follows:
    Atomized mechanical application means application of resin or gel 
coat with spray equipment that separates the liquid into a fine mist. 
This fine mist may be created by forcing the liquid under high pressure 
through an elliptical orifice, bombarding a liquid stream with directed 
air jets, or a combination of these techniques.
    Bulk molding compound (BMC) means a putty-like molding compound 
containing resin(s) in a form that is ready to mold. In addition to 
resins, BMC may contain catalysts, fillers, and reinforcements. Bulk

molding operations to manufacture reinforced plastic composites 
products.
    BMC manufacturing means a process that involves the preparation of 
BMC.
    Centrifugal casting means a process for fabricating cylindrical 
composites, such as pipes, in which composite materials are positioned 
inside a rotating hollow mandrel and held in place by centrifugal forces 
until the part is sufficiently cured to maintain its physical shape.
    Charge means the amount of SMC or BMC that is placed into a 
compression or injection mold necessary to complete one mold cycle.
    Cleaning means removal of composite materials, such as cured and 
uncured resin from equipment, finished surfaces, floors, hands of

It can be used to form the surface layer of any composites other than 
those used for molds in tooling operations.
    Closed molding means a grouping of processes for fabricating 
composites in a way that HAP-containing materials are not exposed to the 
atmosphere except during the material loading stage (e.g., compression 
molding, injection molding, and resin transfer molding). Processes where 
the mold is covered with plastic (or equivalent material) prior to resin 
application, and the resin is injected into the covered mold are also 
considered closed molding.
    Composite means a shaped and cured part produced by using composite 
materials.
    Composite materials means the raw materials used to make composites. 
The raw materials include styrene containing resins. They may also 
include gel coat, monomer, catalyst, pigment, filler, and reinforcement.

the closed molding process. The composite materials used in this process 
are generally SMC or BMC.
    Compression/injection molding means a grouping of processes that 
involves the use of compression molding and/or injection molding.
    Continuous casting means a continuous process for fabricating 
composites in which composite materials are placed on an in-line 
conveyor belt to produce cast sheets that are cured in an oven.
    Continuous lamination means a continuous process for fabricating 
composites in which composite materials are typically sandwiched between 
plastic films, pulled through compaction rollers, and cured in an oven. 
This process is generally used to produce flat or corrugated products on 
an in-line conveyor.
    Continuous lamination/casting means a grouping of processes that 
involves the use of continuous lamination and/or continuous casting.
    Controlled emissions means those organic HAP emissions that are 
vented from a control device to the atmosphere.
    Corrosion-resistant gel coat means a gel coat used on a product made 
with a corrosion-resistant resin that has a corrosion-resistant end-use 
application.

the product is manufactured specifically for an application that 
requires a level of chemical inertness or resistance to chemical attack 
above that required for typical reinforced plastic composites products. 
These applications include, but are not limited to, chemical processing 
and storage; pulp and paper production; sewer and wastewater treatment; 
power generation; potable water transfer and storage; food and drug 
processing; pollution or odor control; metals production and plating;

temporary chemical exposures.
    Corrosion-resistant resin means a resin that either:
    (1) Displays substantial retention of mechanical properties when 
undergoing ASTM C-581 coupon testing, where the resin is exposed for 6 
months or more to one of the following materials: Material with a pH 
= 12.0 or <= 3.0, oxidizing or reducing agents, organic 
solvents, or fuels or additives as defined in 40 CFR 79.2. In the coupon 
testing, the exposed resin needs to demonstrate a minimum of 50 percent 
retention of the relevant mechanical property compared to the same resin 
in unexposed condition. In addition, the exposed resin needs to 
demonstrate an increased retention of the relevant mechanical property 
of at least 20 percentage points when compared to a similarly exposed 
general-purpose resin. For example, if the general-purpose resin retains 
45 percent of the relevant property when tested as specified above, then 
a corrosion-resistant resin needs to retain at least 65 percent (45 
percent plus 20 percent) of its property. The general-purpose resin used 
in the test needs to have an average molecular weight of greater than 
1,000, be formulated with a 1:2 ratio of maleic anhydride to phthalic 
anhydride and 100 percent diethylene glycol, and a styrene content 
between 43 to 48 percent; or
    (2) Complies with industry standards that require specific exposure 
testing to corrosive media, such as UL 1316, UL 1746, or ASTM F-1216.

vibrating the mold to remove bubbles. The composite materials may or may 
not include reinforcements. Products produced by the polymer casting 
process include cultured marble products and polymer concrete.
    Preform Injection means a form of pultrusion where liquid resin is 
injected to saturate reinforcements in an enclosed system containing one 
or more chambers with openings only large enough to admit

fugitive organic HAP emissions in the workplace.
    Uncontrolled wet-out area organic HAP emissions means any or all of 
the following: Organic HAP emissions from wet-out areas that do not have 
any

[[Page 995]]

capture and control, organic HAP emissions that escape from wet-out area 
enclosures, and organic HAP emissions from wet-out areas that are 
captured by an enclosure but are vented to the atmosphere and not to an 
add-on control device.
    Unfilled means that there has been no addition of fillers to a resin 
or that less than 10 percent of fillers by weight of the total resin 
plus filler mixture has been added.
    Vapor suppressant means an additive, typically a wax, that migrates 
to the surface of the resin during curing and forms a barrier to seal in 
the styrene and reduce styrene emissions.
    Vapor-suppressed resin means a resin containing a vapor suppressant 
added for the purpose of reducing styrene emissions during curing.
    White and off-white gel coat means a gel coat that contains 10 
percent of more titanium dioxide by weight.

------------------------------------------------------------------------
\1\ Organic HAP emissions limits for open molding and centrifugal
  casting are expressed as lb/ton. You must be at or below these values
  based on a 12-month rolling average.
\2\ This emission limit applies regardless of whether the shrinkage
  controlled resin is used as a production resin or a tooling resin.
\3\ If you only apply gel coat with manual application, for compliance
  purposes treat the gel coat as if it were applied using atomized spray
  guns to determine both emission limits and emission factors. If you
  use multiple application methods and any portion of a specific gel
  coat is applied using nonatomized spray, you may use the nonatomized
  spray gel coat equation to calculate an emission factor for the
  manually applied portion of that gel coat. Otherwise, use the atomized
  spray gel coat application equation to calculate emission factors.
\4\ For compliance purposes, calculate your emission factor using only
  the appropriate centrifugal casting equation in item 2 of Table 1 to
  this subpart, or a site specific emission factor for after the mold is
  closed as discussed in Sec. 63.5796.
\5\ Calculate your emission factor using the appropriate open molding
  covered cure emission factor in item 1 of Table 1 to this subpart, or
  a site specific emission factor as discussed in Sec. 63.5796.
\6\ Pultrusion machines that produce parts that meet the following
  criteria: 1,000 or more reinforcements or the glass equivalent of
  1,000 ends of 113 yield roving or more; and have a cross sectional
  area of 60 square inches or more are not subject to this requirement.
  Their requirement is the work practice of air flow management which is
  described in Table 4 to this subpart.

------------------------------------------------------------------------
\1\ Organic HAP emissions limits for open molding and centrifugal
  casting expressed as lb/ton are calculated using the equations shown
  in Table 1 to this subpart. You must be at or below these values based
  on a 12-month rolling average.
\2\ These limits are for spray application of gel coat. Manual gel coat
  application must be included as part of spray gel coat application for
  compliance purposes using the same organic HAP emissions factor
  equation and organic HAP emissions limit. If you only apply gel coat
  with manual application, treat the manually applied gel coat as if it
  were applied with atomized spray for compliance determinations.
\3\ Centrifugal casting operations where the mold is not vented during
  spinning and cure are considered to be closed molding and are not
  subject to any emissions limit. Centrifugal casting operations where
  the mold is not vented during spinning and cure, and the resin is
  applied to the open centrifugal casting mold using mechanical or
  manual open molding resin application techniques are considered to be
  open molding operations and the appropriate open molding emission
  limits apply.
\4\ Centrifugal casting operations where the mold is vented during
  spinning and the resin is applied to the open centrifugal casting mold
  using mechanical or manual open molding resin application techniques,
  use the appropriate centrifugal casting emission limit to determine
  compliance. Calculate your emission factor using the appropriate
  centrifugal casting emission factor in Table 1 to this subpart, or a
  site specific emission factor as discussed in Sec. 63.5796.

Sec. Appendix A to Subpart WWWW of Part 63--Test Method for Determining 
                     Vapor Suppressant Effectiveness

                        1. Scope and Application

    1.1 Applicability. If a facility is using vapor suppressants to 
reduce hazardous air pollutant (HAP) emissions, the organic HAP emission 
factor equations in Table 1 to this subpart require that the vapor 
suppressant effectiveness factor be determined. The vapor suppressant 
effectiveness factor is then used as one of the inputs into the 
appropriate organic HAP emission factor equation. The vapor suppressant 
effectiveness factor test is not intended to quantify overall volatile 
emissions from a resin, nor to be used as a stand-alone test for 
emissions determination. This test is designed to evaluate the 
performance of film forming vapor suppressant resin additives. The 
results of this test are used only in combination with the organic HAP 
emissions factor equations in Table 1 to this subpart to generate 
emission factors.
    1.1.1 The open molding process consists of application of resin and 
reinforcements to the mold surface, followed by a manual rollout process 
to consolidate the laminate, and the curing stage where the laminate 
surface is not disturbed. Emission studies have shown that approximately 
50 percent to 55 percent of the emissions occur while the resin is being 
applied to the mold. Vapor suppressants have little effect during this 
portion of the lamination process, but can have a significant effect 
during the curing stage. Therefore, if a suppressant is 100 percent 
effective, the overall emissions from the process would be reduced by 45 
percent to 50 percent, representing the emissions generated during the 
curing stage. In actual practice, vapor suppressant effectiveness will 
be less than 100 percent and the test results determine the specific 
effectiveness in terms of the vapor suppressant effectiveness factor. 
This factor represents the effectiveness of a specific combination of 
suppressant additive and resin formulation.
    1.1.2 A resin manufacturer may supply a molder with a vapor-
suppressed resin, and employ this test to provide the molder with the 
vapor suppressant effectiveness factor for that combination of resin and 
vapor suppressant. The factor qualifies the effectiveness of the vapor 
suppressant when the resin is tested in the specific formulation 
supplied to the molder. The addition of fillers or other diluents by the 
molder may impact the effectiveness of the vapor suppressant. The 
formulation, including resin/glass ratio and filler content, used in the 
test should be similar to the formulation to be used in production. The 
premise of this method is to compare laminate samples made with vapor 
suppressant additive and made without the additive. The difference in 
emissions between the two yields the vapor suppressant effectiveness 
factor.
    1.1.3 The method uses a mass balance determination to establish the 
relative loss of the volatile component from unsaturated polyester or 
vinyl ester resins, with and without vapor suppressant additives. The 
effectiveness of a specific vapor suppressant and resin mixture is 
determined by comparing the relative volatile weight losses from vapor 
suppressed and non-suppressed resins. The volatile species are not 
separately analyzed. While the species contained in the volatile 
component are not determined, an extended listing of potential monomer 
that may be contained in unsaturated polyester or vinyl ester resins is 
provided in Table 1.1. However, most polyester and vinyl ester resin 
formulations presently used by the composites industry only contain 
styrene monomer.

    2.1 Differences in specific resin and suppressant additive chemistry 
affect the performance of a vapor suppressant. The purpose of this 
method is to quantify the effectiveness of a specific combination of 
vapor

[[Page 1015]]

suppressant and unsaturated polyester or vinyl ester resin as they are 
to be used in production. This comparative test quantifies the loss of 
volatiles from a fiberglass reinforced laminate during the roll-out and 
curing emission phases, for resins formulated with and without a 
suppressant additive. A criterion for this method is the testing of a 
non-vapor suppressed resin system and testing the same resin with a 
vapor suppressant. The two resins are as identical as possible with the 
exception of the addition of the suppressant to one. The exact 
formulation used for the test will be determined by the in-use 
production requirements. Each formulation of resin, glass, fillers, and 
additives is developed to meet particular customer and or performance 
specifications.
    2.2 The result of this test is used as an input factor in the 
organic HAP emissions factor equations in Table 1 to this subpart, which 
allows these equations to predict emissions from a specific combination 
of resin and suppressant. This test does not provide an emission rate 
for the entire lamination process.

                           11. Test Procedure

    11.1 Test Set-up.
    11.1.1 The laboratory balance is located in an enclosure to prevent 
fluctuations in balance readings due to localized air movement. The 
front of enclosure is open to permit work activity, but positioned so 
that local airflow will not effect balance readings. The ambient 
temperature is determined by suspending the thermometer at a point 
inside the enclosure.
    11.1.2 The bottom of the aluminum pan is covered with the Mylar 
film. The film is held in position with tape or by friction between the 
pan and the film.
    11.1.3 The resin and pan are brought to room temperature. This test 
temperature must be between 70 [deg]F and 80 [deg]F. The testing 
temperature cannot vary more than 2 [deg]F during 
the measurement of test runs. Temperature shall be recorded at the same 
time weight is recorded on suppressed and non-suppressed test data 
sheets, shown in Table 17.1.
    11.1.4 The relative humidity may not change more than 15 percent during the test runs. This is determined by 
recording the relative humidity in the vicinity of the test chamber at 
the beginning and end of an individual test run. This data is recorded 
on the test data sheets shown in Table 17.1.
    11.1.5 Two plies of nominal 1.5 oz/ft\2\ chopped strand mat (CSM) 
are cut into a square or rectangle with the minimum surface area of 60 
square inches (i.e. a square with a side dimension of 7.75 inches).
    11.1.6 The appropriate resin application roller is readily 
available.
    11.2 Resin Gel Time/Initiator Percentage
    11.2.1 Previous testing has indicated that resin gel time influences 
the emissions from composite production. The testing indicated that 
longer the gel times led to higher emissions. There are a number of 
factors that influence gel time including initiator type, initiator 
brand, initiator level, temperature and resin additives. Under actual 
usage conditions a molder will adjust the initiator to meet a gel time 
requirement. In this test procedure, the vapor suppressed and non-vapor 
suppressed resin systems will be adjusted to the same gel time by 
selecting the appropriate initiator level for each.
    11.2.2 All test runs within a test will be processed in a manner 
that produces the same resin gel time 2 minutes. 
To facilitate the resin mixing procedure, master batches of resin and 
resin plus vapor suppressant of resin are prepared. These resin master 
batches will have all of the required ingredients except initiator; this 
includes filler for filled systems. The gel times for the tests are 
conducted using the master batch and adjustments to meet gel time 
requirements shall be made to the master batch before emission testing 
is conducted. Test temperatures must be maintained within the required 
range, during gel time testing. Further gel time testing is not required 
after the non-vapor suppressed and vapor suppressed master batches are 
established with gel times within 2 minutes. A 
sufficient quantity of each resin should be prepared to allow for 
additional test specimens in the event one or more test fails to meet 
the data acceptance criteria discussed in Section 11.5 and shown in 
Table 17.2.
    11.2.3 The specific brand of initiator and the nominal percentage 
level recommended by the resin manufacturer will be indicated on the 
resin certificate of analysis \15\; or, if a unique gel time is required 
in a production laminate, initiator brand and percentage will be 
determined by that specific requirement.
    11.2.4 Examples:

[[Page 1017]]

    11.2.4.1 The resin for a test run is specified as having a 15-minute 
cup gel time at 77 [deg]F using Brand X initiator at 1.5 percent by 
weight. The non-suppressed control resin has a 15-minute gel time. The 
suppressed resin has a gel time of 17-minutes. An initiator level of 1.5 
percent would be selected for the both the non-suppressed and the 
suppressed test samples.
    11.2.4.2 Based on a specific production requirement, a resin is 
processed in production using 2.25 percent of Brand Y initiator, which 
produces a 20-minute gel time. This initiator at level of 2.25 percent 
produces a 20 minute gel time for the non-suppressed control resin, but 
yields a 25-minute gel time for the suppressed resin sample. The 
suppressed resin is retested at 2.50 percent initiator and produces a 
21-minute gel time. The initiator levels of 2.25 percent and 2.50 
percent respectively would yield gel times within 2 minutes.
    11.3 Test Run Procedure for Unfilled Resin (see the data sheet shown 
in Table 17.1).
    11.3.1 The insulating board is placed on the balance.
    11.3.2 The aluminum pan with attached Mylar film is placed on the 
balance, and the balance is tared (weight reading set to zero with the 
plate on the balance.)
    11.3.3 Place two plies of 1.5 oz. CSM on the balance and record the 
weight (glass weight).
    11.3.4 The resin beaker and stirring rod are put on the second 
balance and tared.
    11.3.5 The required resin weight and initiator weight are calculated 
(refer to calculation formulas in 12.2).
    11.3.6 The disposable resin application roller is placed on the edge 
of the plate.
    11.3.7 The balance is tared, with the aluminum pan, Mylar film, 
glass mat, and resin application roller on the balance pan.
    11.3.8 Resin is weighed into a beaker, as calculated, using the 
second balance. The mixing stick should be tared with the beaker weight.
    11.3.9 Initiator is weighed into the resin, as calculated, using an 
eyedropper or a pipette, and the combination is mixed.
    11.3.10 Initiated resin is poured on chopped strand mat in a pe-
determined pattern (see Figure 11.6).
    11.3.11 A stopwatch is started from zero.
    11.3.12 The initial laminate weight is recorded.
    11.3.13 The plate is removed from balance to enable roll-out of the 
laminate.
    11.3.14 The wet laminate is rolled with the resin application roller 
to completely distribute the resin, saturate the chopped strand mat, and 
eliminate air voids. Roll-out time should be in the range of 2 to 3\16\ 
minutes and vary less than 10 percent of the 
average time required for the complete set of six suppressed and six 
non-suppressed runs.
    11.3.15 Record the rollout end time (time from start to completion 
of rollout).
    11.3.16 Place the resin application roller on the edge of the plate 
when rollout is completed.
    11.3.17 Place the plate back on the balance pan. Immediately record 
the weight.
    11.3.18 For the first test in a series of six tests, weight is 
recorded every 5-minute interval (suppressed and non-suppressed). The 
end of the test occurs when three consecutive equal weights are recorded 
or a weight gain is observed (the last weight before the increased 
weight is the end of test weight). For the remaining five tests in the 
series, after the initial weights are taken, the next weight is recorded 
30 minutes before the end of the test, as suggested by the results from 
the first test. It is likely that the time to reach the end point of a 
suppressed resin test will be shorter than the time required to complete 
a non-suppressed test. Therefore, the time to start taking data manually 
may be different for suppressed and non-suppressed resins.
    11.4 Test Run Procedures for Filled Resin Systems \17\ Note that the 
procedure for filled systems differs from the procedure for unfilled 
systems. With filled systems, resin is applied to one ply of the CSM and 
the second ply is placed on top of the resin.
    11.4.1 The insulating board is placed on the balance.
    11.4.2 The aluminum pan with attached Mylar film is placed on the 
balance, and the balance is tared (weight reading set to zero with the 
plate on the balance.)
    11.4.3 Place two plies of 1.5 oz. CSM on the balance and record the 
weight (glass weight).
    11.4.4 Remove the top ply of fiberglass and record its weight 
(weight of 1st layer of glass).
    11.4.5 The required resin weight and initiator weight are calculated 
(refer to calculation formulas in 12.2). Calculate the weight of filled 
resin and initiator based on the 2 layers of fiberglass.
    11.4.6 The resin beaker and stirring rod are put on the second 
balance and tared.
    11.4.7 A disposable resin application roller is placed on the edge 
of the plate.
    11.4.8 The balance is tared, with the aluminum pan, Mylar film, 
glass mat, and resin application roller on the balance pan.
    11.4.9 Resin is weighed into the beaker, as calculated, using the 
second balance. The mixing stick should be tared with the beaker weight.
    11.4.10 Initiator is weighed into the resin, as calculated, using an 
eyedropper or a pipette, and the combination is mixed.
    11.4.11 Initiated resin is poured on the single ply of CSM in a pre-
determined pattern. Refer to Figure 11.6.
    11.4.12 A stopwatch is started from zero.
    11.4.13 Record the weight of the resin ans single ply of CSM 
(L1). The initial laminate

[[Page 1018]]

weight equals L1 plus the weight of second glass layer.
    11.4.14 Replace the second layer of fiberglass.
    11.4.15 Remove the plate from the balance to allow roll-out of the 
laminate.
    11.4.16 Roll the wet laminate with the resin application roller to 
completely distribute the resin, saturate the chopped strand mat, and 
eliminate air voids. Roll-out time should be in the range of 2 to 3\16\ 
minutes and vary less than 10 percent of the 
average time required for the complete set of six suppressed and six 
non-suppressed runs.
    11.4.17 Record the roll-out end time (time from start to completion 
of rollout).
    11.4.18 Place the resin application roller on the edge of the plate 
when rollout is completed.
    11.4.19 Place the plate back on the balance pan. The initial weight 
is recorded immediately.
    11.4.20 For the first test run in a series of six, weight is 
recorded at every 5-minute interval (suppressed and non-suppressed). The 
end of the test occurs when three consecutive equal weights are recorded 
or a weight gain is observed (the last weight before the increased 
weight is the end of test weight). For the remaining five tests in the 
series, after the initial weights are taken, the next weight is recorded 
30 minutes before the end of the test, as suggested by the results from 
the first test. It is likely that the time to reach the end point of a 
suppressed resin test will be shorter than the time required to complete 
a non-suppressed test. Therefore, the time to start taking data manually 
may be different for suppressed and non-suppressed resins.
    11.5 Data Acceptance Criteria:
    11.5.1 A test set is designed as twelve individual test runs using 
the same resin, initiator, and gel time, six of the test runs use the 
resin non-vapor suppressed and the other six use it vapor suppressed.
    11.5.2 If a test run falls outside any of the time, temperature, 
weight or humidity variation requirements, it must be discarded and run 
again.
    11.5.3 The laminate roll out time for each individual test run must 
vary less than 10 percent of the average time 
required for the complete set of six suppressed and six non-suppressed 
runs.
    11.5.4 Test temperature for each test run must be maintained within 
2 [deg]F and the average must be between 70[deg] 
and 80 [deg]F. Refer to 11.1.3.
    11.5.5 The difference in the amount of resin for each run must be 
within 10 percent of the average weight for the 
complete set of six suppressed and six non-suppressed runs.
    11.5.6 The relative humidity from each test run must be within 
15 percent of the average humidity for the 
complete set of six suppressed and six non-suppressed tests. Refer to 
11.1.4
    11.5.7 The glass content for each test set must be within 10 percent of the average resin-to-/glass ratio for the 
complete set of six suppressed and six non-suppressed runs. Refer to 
12.2).
    11.5.8 The filler content for each test of a test set must be within 
5 percent of the average filler content for the 
complete set of six suppressed and six non-suppressed runs. Refer to 
12.2.
    11.6 Resin Application Pour Pattern:
    11.6.1 To facilitate the distribution of resin across the chopped 
strand mat, and to provide consistency from test to test, a uniform pour 
pattern should be used. A typical pour pattern is shown below:

[[Page 1019]]

[GRAPHIC] [TIFF OMITTED] TR21AP03.009

    11.6.2 The resin is to be evenly distributed across the entire 
surface of the chopped strand mat using the resin application roller to 
achieve a wet look across the surface of the laminate. Pushing excess 
resin off the reinforcement and onto the Mylar sheet should be avoided. 
No resin is to be pushed more than \1/2\ inch beyond the edge of the 
glass mat. If excess resin is pushed further from the glass mat, it will 
void the test run. As part of this process, typical visible air voids 
are to be eliminated by the rollout process. If the pour pattern is 
different from the above, it must be recorded and attached to test data 
sheet 17.1.

                   12. Data Analysis and Calculations

    12.1 Data Analysis:
    This test method requires a simple mass balance calculation, no 
special data analysis is necessary.
    12.2 Calculations:
    12.2.1 The target glass content (percent) for unfilled resin systems 
is determined from the specific production parameters being evaluated. 
In absence of any specific production requirements the target may be set 
at the tester's discretion.
    12.2.2 Glass content determination (expressed as a per cent):

% Glass = Glass wt(g)/(Glass wt(g) + Resin weight (g))

    12.2.3 Weight of resin required:
    Resin weight required = (Glass wt (g)/% glass)--Glass wt (g)
    12.2.4 Filled resin formulation determination for filled resin 
systems (e.g. 30 percent filler by weight for a particulate 
filler, or 1 percent by weight for a lightweight filler, such 
as hollow microspheres):

% Resin content = resin
weight(g)/(resin weight(g) + glass
weight(g) + filler weight(g))
% Glass content = glass
weight(g)/(resin weight(g) + glass
weight(g) + filler weight(g))
Filler content = filler
weight(g)/(resin weight(g) + glass
weight(g) + filler weight(g))

    12.2.5 Initiator weight determination:

Initiator weight (g) = Resin weight(g) x Initiator %

    12.2.6 Emission weight loss determination:
    Emissions weight loss (g) = Initial resin weight (g)-Final resin 
weight (g)
    12.2.7 % Emission weight loss:

% Emission Weight Loss = (Emission weight loss (g) Initial resin weight 
          (g) x 100

    12.2.8 Average % Emission Weight Loss (assuming six test runs):

[[Page 1020]]

    12.2.9 VSE Factor calculation:

VSE Factor = 1 -(Average % VS Emission Weight Loss/Average NVS Emission 
          Weight Loss)

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

    VSE Factor = 0.45

    VSE Factor is used as input into the appropriate equation in Table 1 
to this subpart.
    Example from Table 1 to this subpart:

Manual Resin Application, 35 percent HAP resin, VSE Factor of 0.45
HAP Emissions with vapor suppresants = ((0.286 x %HAP)-0.0529) x 2000 x 
          (1-(0.5 x VSE factor))
HAP Emissions with vapor suppresants = ((0.286 x .35)-0.0529) x 2000 x 
          (1-(0.5 x .45))
HAP Emissions with vapor suppresants = 73 pounds of HAP emissions per 
          ton of resin.

                         13. Method Performance

    13.1 Bias:
    The bias of this test method has not been determined.
    13.2 Precision Testing
    13.2.1 Subsequent to the initial development of this test protocol 
by the Composites Fabricators Association, a series of tests were 
conducted in three different laboratory facilities. The purpose of this 
round robin testing was to verify the precision of the test method in 
various laboratories. Each laboratory received a sample of an 
orthophthalic polyester resin from the same production batch, containing 
48 per cent styrene by weight. Each testing site was also provided with 
the same vapor suppressant additive. The suppressant manufacturer 
specified the percentage level of suppressant additive. The resin 
manufacturer specified the type and level of initiator required to 
produce a 20 minute gel time. The target glass content was 30 percent by 
weight.
    13.2.2 Each laboratory independently conducted the VSE test 
according to this method. A summary of the results is included in Table 
13.1.

    13.3 Comparison to EPA Reference Methods This test has no 
corresponding EPA reference method.

                        14. Pollution Prevention

    The sample size used in this method produces a negligible emission 
of HAP, and has an insignificant impact upon the atmosphere.

                          15. Waste Management

    The spent and waste materials generated during this test are 
disposed according to required facility procedures, and waste management 
recommendations on the corresponding material safety data sheets.

    \1\ Balance Enclosure--The purpose of the balance enclosure is to 
prevent localized airflow from adversely affecting the laboratory 
balance. The enclosure may be a simple three-sided box with a top and an 
open face. The configuration of the enclosure is secondary to the 
purpose of providing a stable and steady balance reading, free from the 
effects of airflow, for accurate measurements. The enclosure can be 
fabricated locally. A typical enclosure is shown in Figure 17.1.

    \15\ Certificate of Analysis: Resin gel time, as recorded on the 
resin certificate of analysis, is measured using a laboratory standard 
gel time procedure. This procedure typically uses a 100 gram cup sample 
at 77 [deg]F (25 [deg]C), a specific type of initiator and a specified 
percentage.
    \16\ Roll-out times may vary with resin viscosity or resin additive. 
The important aspect of this step is to produce the same roll-out time 
for both the suppressed and non-suppressed samples.
    \17\ While this test can be used with filled resin systems, the test 
is not designed to determine the effect of the filler on emissions, but 
rather to measure the effect of the suppressant additive in the resin 
system. When evaluating a filled system both the non-vapor suppressed 
and vapor suppressed samples should be formulated with the same type and 
level of filler.

Subpart XXXX_National Emissions Standards for Hazardous Air Pollutants: 
                        Rubber Tire Manufacturing

    Source: 67 FR 45598, July 9, 2002, unless otherwise noted.

                        What This Subpart Covers



Sec. 63.5980  What is the purpose of this subpart?

    This subpart establishes national emission standards for hazardous 
air pollutants (NESHAP) for rubber tire manufacturing. This subpart also 
establishes requirements to demonstrate

[[Page 1029]]

initial and continuous compliance with the emission limitations.



Sec. 63.5981  Am I subject to this subpart?

    (a) You are subject to this subpart if you own or operate a rubber 
tire manufacturing facility that is located at, or is a part of, a major 
source of hazardous air pollutant (HAP) emissions.
    (1) Rubber tire manufacturing includes the production of rubber 
tires and/or the production of components integral to rubber tires, the 
production of tire cord, and the application of puncture sealant. 
Components of rubber tires include, but are not limited to, rubber 
compounds, sidewalls, tread, tire beads, tire cord and liners. Other 
components often associated with rubber tires but not integral to the 
tire, such as wheels, inner tubes, tire bladders, and valve stems, are 
not components of rubber tires or tire cord and are not subject to this 
subpart.
    (2) A major source of HAP emissions is any stationary source or 
group of stationary sources within a contiguous area and under common 
control that emits or has the potential to emit considering controls, in 
the aggregate, any single HAP at a rate of 9.07 megagrams (10 tons) or 
more per year or any combination of HAP at a rate of 22.68 megagrams (25 
tons) or more per year.
    (b) You are not subject to this subpart if the affected source at 
your rubber tire manufacturing facility meets either of the conditions 
described in paragraph (b)(1) or (2) of this section.
    (1) You own or operate a tire cord production affected source, but 
the primary product produced at the affected source is determined to be 
subject to another subpart under this part 63 as of the effective date 
of that subpart (publication date of the final rule) or startup of the 
source, whichever is later. In this case, you must determine which 
subpart applies to your source and you must be in compliance with the 
applicable subpart by the compliance date of that subpart. The primary 
product is the product that is produced for the greatest operating time 
over a 5-year period, based on expected utilization for the 5 years 
following the compliance date or following initial startup of the 
source, whichever is later.
    (2) Your rubber tire manufacturing affected source is a research and 
development facility whose primary purpose is to conduct research and 
development into new processes and products, where such source is 
operated under the close supervision of technically trained personnel 
and is not engaged in the manufacture of products for commercial sale in 
commerce, except in a de minimis manner.



Sec. 63.5982  What parts of my facility does this subpart cover?

    (a) This subpart applies to each existing, new, or reconstructed 
affected source at facilities engaged in the manufacture of rubber tires 
or their components.
    (b) The affected sources are defined in paragraph (b)(1) of this 
section (tire production), paragraph (b)(2) of this section (tire cord 
production), paragraph (b)(3) of this section (puncture sealant 
application), and paragraph (b)(4) of this section (rubber processing).
    (1) The tire production affected source is the collection of all 
processes that use or process cements and solvents as defined in Sec. 
63.6015, located at any rubber tire manufacturing facility. It includes, 
but is not limited to: Storage and mixing vessels and the transfer 
equipment containing cements and/or solvents; wastewater handling and 
treatment operations; tread and cement operations; tire painting 
operations; ink and finish operations; undertread cement operations; 
process equipment cleaning materials; bead cementing operations; tire 
building operations; green tire spray operations; extruding, to the 
extent cements and solvents are used; cement house operations; marking 
operations; calendar operations, to the extent solvents are used; tire 
striping operations; tire repair operations; slab dip operations; other 
tire building operations, to the extent that cements and solvents are 
used; and balance pad operations.
    (2) The tire cord production affected source is the collection of 
all processes engaged in the production of tire cord. It includes, but 
is not limited to: dipping operations, drying ovens, heat-set

[[Page 1030]]

ovens, bulk storage tanks, mixing facilities, general facility vents, 
air pollution control devices, and warehouse storage vents.
    (3) The puncture sealant application affected source is the puncture 
sealant application booth operation used to apply puncture sealant to 
finished tires.
    (4) The rubber processing affected source is the collection of all 
rubber mixing processes (e.g., banburys and associated drop mills) that 
either mix compounds or warm rubber compound before the compound is 
processed into components of rubber tires. The mixed rubber compound 
itself is also included in the rubber processing affected source. There 
are no emission limitations or other requirements for the rubber

Testing and Initial Compliance Requirements for Tire Production Affected 
                                 Sources



Sec. 63.5994  How do I conduct tests and procedures for tire
production affected sources?

    (a) Methods to determine the mass percent of HAP in cements and 
solvents. To determine the HAP content in the cements and solvents used 
at your tire production affected source, use EPA Method 311 of appendix 
A of this part, an approved alternative method, or any other reasonable 
means for determining the HAP content of your cements and solvents. 
Other reasonable means include, but are not limited to: a material 
safety data sheet (MSDS), provided it contains appropriate information; 
a certified product data sheet (CPDS); or a manufacturer's hazardous air 
pollutant data sheet. You are not required to test the materials that 
you use, but the Administrator may require a test using EPA Method 311 
(or an approved alternative method) to confirm the reported HAP content. 
If the results of an analysis by EPA Method 311 are different from the 
HAP content determined by another means, the EPA Method 311 results will 
govern compliance determinations.
    (b) Methods to demonstrate compliance with the HAP constituent 
emission limits in Table 1 to this subpart (option 1). Use the method in 
paragraph (b)(1) of this section to demonstrate initial and continuous 
compliance with the applicable emission limits for tire production 
affected sources using the compliance alternative described in Sec. 
63.5985(a), purchase alternative. Use the equations in paragraphs (b)(2) 
and (3) of this section to demonstrate initial and continuous compliance 
with the emission limits for tire production affected sources using the 
monthly average compliance alternatives described in Sec. 63.5985(b) 
and (c).
    (1) Determine the mass percent of each HAP in each cement and 
solvent according to the procedures in paragraph (a) of this section.

rate for each monthly operating period when complying by using cements 
and solvents without using an add-on control device so that the monthly 
average HAP emissions do not exceed the HAP constituent emission limits 
in Table 1 to this subpart, option 1. Equation 1 follows:

    (d) Specific compliance demonstration requirements for tire 
production affected

[[Page 1036]]

sources. (1) Conduct any required compliance demonstration according to 
the requirements in Sec. 63.5993.
    (2) If you are demonstrating compliance with the HAP constituent 
option in Table 1 to this subpart, option 1, conduct the compliance 
demonstration using cements and solvents that are representative of 
cements and solvents typically used at your tire production affected 
source.
    (3) Establish an operating range that corresponds to the control 
efficiency as described in Table 5 to this subpart.
    (e) How to take credit for HAP emissions reductions from add-on 
control devices. If you want to take credit in Equations 2 and 4 of this 
section for HAP emissions reduced using a control system, you must meet 
the requirements in paragraphs (e)(1) and (2) of this section.
    (1) Monitor the established operating parameters as appropriate.

stream mass or volumetric flow for each regeneration cycle, and the 
carbon bed temperature after each regeneration, and within 15 minutes of 
completing any cooling cycle.
    (iii) If you use a control device other than a thermal oxidizer or a 
regenerative carbon adsorber, install and operate a continuous parameter 
monitoring system according to your site-specific performance test plan 
submitted according to Sec. 63.7(c)(2)(i).
    (iv) If you use a permanent total enclosure, monitor the face 
velocity across the natural draft openings (NDO) in the enclosure. Also, 
if you use an enclosure, monitor to ensure that the sizes of the NDO 
have not changed, that there are no new NDO, and that a HAP emission 
source has not been moved closer to an NDO since the last compliance 
demonstration was conducted.

identified in your monitoring plan.
    (2) Maintain the operating parameters within the operating range 
established during the compliance demonstration.
    (f) How to take credit for HAP emissions reductions when streams are 
combined. When performing material balances to demonstrate compliance, 
if the storage of materials, exhaust, or the wastewater from more than 
one affected source are combined at the point where control systems are 
applied, any credit for emissions reductions needs to be prorated among 
the affected sources based on the ratio of their contribution to the 
uncontrolled emissions.

  Testing and Initial Compliance Requirements for Tire Cord Production 
                            Affected Sources



Sec. 63.5997  How do I conduct tests and procedures for tire cord
production affected sources?

    (a) Methods to determine the mass percent of each HAP in coatings. 
(1) To determine the HAP content in the coating used at your tire cord 
production affected source, use EPA Method 311 of appendix A of this 
part, an approved alternative method, or any other reasonable means for 
determining the HAP content of your coatings. Other reasonable means 
include, but are not limited

[[Page 1038]]

to: an MSDS, provided it contains appropriate information; a CPDS; or a 
manufacturer's HAP data sheet. You are not required to test the 
materials that you use, but the Administrator may require a test using 
EPA Method 311 (or an approved alternative method) to confirm the 
reported HAP content. If the results of an analysis by EPA Method 311 
are different from the HAP content determined by another means, the EPA 
Method 311 results will govern compliance determinations.
    (2) Unless you demonstrate otherwise, the HAP content analysis must 
be based on coatings prior to any cross-linking reactions, i.e., curing. 
However, you may account for differences in HAP emissions resulting from 
chemical reactions based on the conversion rates of the individual 
coating formulations, chemistry demonstrations, or other demonstrations 
that are verifiable to the approving agency. Use the revised value in 
your compliance demonstration in the relevant equations in paragraph (b) 
of this section.
    (b) Methods to determine compliance with the emission limits in 
Table 2 to this subpart, option 1. Use the equations in this paragraph 
(b) to demonstrate initial and continuous compliance with the emission 
limits for tire cord production sources using the compliance 
alternatives described in Sec. 63.5987(a) and (b).
    (1) Determine mass percent of HAP. Determine the mass percent of all 
HAP in each coating according to the procedures in paragraph (a) of this 
section.
    (2) Compliance without use of an add-on control device. If you do 
not use an add-on control device to meet the emission limits, use 
Equation 1 of this section to calculate the monthly HAP emission rate in 
grams of HAP emitted per megagram of fabric processed at the tire cord 
production source to show that the monthly average HAP emissions do not 
exceed the emission limits in Table 2 to this subpart, option 1.

emitted per megagram of fabric processed to show that the monthly 
average HAP emissions do not exceed the HAP emission limit in Table 2 of

          operating days, which are defined as days when either the 
          control system is not operating within the operating range 
          established during the performance test or when monitoring 
          data are not collected.

production affected sources. (1) Conduct any required compliance 
demonstrations according to the requirements in Sec. 63.5993.
    (2) Conduct the compliance demonstration using coatings with average

typically used at your tire cord production affected source.
    (3) Establish an operating range that corresponds to the control 
efficiency as described in Table 5 to this subpart.

control devices. If you want to take credit in Equations 2 and 4 of this 
section for HAP emissions reduced using a control system, you must meet 
the requirements in paragraphs (e)(1) and (2) of this section.
    (1) Monitor the established operating parameters as appropriate.

stream mass or volumetric flow for each regeneration cycle and the 
carbon bed temperature after each regeneration and within 15 minutes of 
completing any cooling cycle.
    (iii) If you use a control device other than a thermal oxidizer or a 
regenerative carbon adsorber, install and operate a continuous parameter 
monitoring system according to your site-specific performance test plan 
submitted according to Sec. 63.7(c)(2)(i).
    (iv) If you use a permanent total enclosure, monitor the face 
velocity

[[Page 1041]]

across the NDO in the enclosure. Also, if you use an enclosure, monitor 
to ensure that the sizes of the NDO have not changed, that there are no 
new NDO, and that a HAP emission source has not been moved closer to an 
NDO since the last performance test was conducted.

methods and equations in paragraph (b) of this section to demonstrate 
initial and continuous compliance with the overall control efficiency 
compliance alternatives described in Sec. 63.5989(a) and (b). Use the 
methods and equations in paragraphs (c) through (g) of this section to 
demonstrate initial and continuous compliance with the HAP constituent 
compliance alternative described in Sec. 63.5989(c) and (d).
    (b) Methods to determine compliance with the emission limits in 
Table 3 to this subpart, option 1. Follow the test procedures described 
in Sec. 63.5993 to determine the overall control efficiency of your 
system.
    (1) You must also meet the requirements in paragraphs (b)(1)(i) and 
(ii) of this section.
    (i) Conduct the performance test using a puncture sealant with an 
average mass percent HAP content that is representative of the puncture 
sealants typically used at your puncture sealant application affected 
source.
    (ii) Establish all applicable operating limit ranges that correspond 
to the control system efficiency as described in Table 5 to this 
subpart.
    (2) Use Equation 1 of this section to calculate the overall 
efficiency of the control system. If you have a permanent total 
enclosure that satisfies EPA Method 204 (found in 40 CFR part 51, 
appendix M) criteria, assume 100 percent capture efficiency for variable 
F. Equation 1 follows:
[GRAPHIC] [TIFF OMITTED] TR09JY02.008


[[Page 1042]]


Where:

completing any cooling cycle.
    (iii) For each control device used other than a thermal oxidizer or 
a regenerative carbon adsorber, install and operate a continuous 
parameter monitoring system according to your site-specific performance 
test plan submitted according to Sec. 63.7(c)(2)(i).
    (iv) If you use a permanent total enclosure, monitor the face 
velocity across the NDO in the enclosure. Also, if you use an enclosure, 
monitor to ensure that the sizes of the NDO have not changed, that there 
are no new NDO, and that a HAP emission source has not been moved closer 
to an NDO since the last performance test was conducted.
    (v) If you use other capture systems, monitor the parameters 
identified in your monitoring plan.

sealants. To determine the HAP content in the puncture sealant used at 
your puncture sealant application affected source, use EPA Method 311 of 
appendix A of 40 CFR part 63, an approved alternative method, or any 
other reasonable means for determining the HAP content of your puncture 
sealants. Other reasonable means include, but are not limited to: an 
MSDS, provided it contains appropriate information; a CPDS; or a 
manufacturer's hazardous air pollutant data sheet. You are not required 
to test the materials that you use, but the Administrator may require a 
test using EPA Method 311 (or an approved alternative method) to confirm 
the reported HAP content. If the results of an analysis by EPA Method 
311 are different from the HAP content determined by another means, the 
EPA Method 311 results will govern compliance determinations.
    (d) Methods to determine compliance with the emission limits in 
Table 3 to this subpart, option 2. Use the equations in this paragraph 
(d) to demonstrate initial and continuous compliance with the HAP 
constituent emission limits for puncture sealant application affected

 Subpart YYYY_National Emission Standards for Hazardous Air Pollutants 
                   for Stationary Combustion Turbines

    Source: 69 FR 10537, Mar. 5, 2004, unless otherwise noted.

                        What This Subpart Covers



Sec. 63.6080  What is the purpose of subpart YYYY?

    Subpart YYYY establishes national emission limitations and operating 
limitations for hazardous air pollutants (HAP) emissions from stationary 
combustion turbines located at major sources of HAP emissions, and 
requirements to demonstrate initial and continuous compliance with the 
emission and operating limitations.



Sec. 63.6085  Am I subject to this subpart?

    You are subject to this subpart if you own or operate a stationary 
combustion turbine located at a major source of HAP emissions.
    (a) Stationary combustion turbine means all equipment, including but 
not limited to the turbine, the fuel, air, lubrication and exhaust gas 
systems, control systems (except emissions control equipment), and any 
ancillary components and sub-components comprising any simple cycle 
stationary combustion turbine, any regenerative/recuperative cycle 
stationary combustion turbine, the combustion turbine portion of any 
stationary cogeneration cycle combustion system, or the combustion 
turbine portion of any stationary combined cycle steam/electric 
generating system. Stationary means that the combustion turbine is not 
self propelled or intended to be propelled while performing its 
function, although it may be mounted on a vehicle for portability or 
transportability. Stationary combustion turbines covered by this subpart 
include simple cycle stationary combustion turbines, regenerative/
recuperative cycle stationary combustion turbines, cogeneration cycle 
stationary combustion turbines, and combined cycle stationary combustion 
turbines. Stationary combustion turbines subject to this subpart do not 
include turbines located at a research or laboratory facility, if 
research is conducted on the turbine itself and the turbine is not being 
used to power other applications at the research or laboratory facility.
    (b) A major source of HAP emissions is a contiguous site under 
common control that emits or has the potential to emit any single HAP at 
a rate of 10 tons (9.07 megagrams) or more per year or any combination 
of HAP at a rate of 25 tons (22.68 megagrams) or more per year, except 
that for oil and gas production facilities, a major source of HAP 
emissions is determined for each surface site.



Sec. 63.6090  What parts of my plant does this subpart cover?

    This subpart applies to each affected source.
    (a) Affected source. An affected source is any existing, new, or 
reconstructed stationary combustion turbine located at a major source of 
HAP emissions.
    (1) Existing stationary combustion turbine. A stationary combustion 
turbine is existing if you commenced construction or reconstruction of 
the stationary combustion turbine on or before January 14, 2003. A 
change in ownership of an existing stationary combustion turbine does 
not make that stationary combustion turbine a new or reconstructed 
stationary combustion turbine.
    (2) New stationary combustion turbine. A stationary combustion 
turbine is new if you commenced construction of the stationary 
combustion turbine after January 14, 2003.
    (3) Reconstructed stationary combustion turbine. A stationary 
combustion turbine is reconstructed if you meet the

[[Page 1064]]

definition of reconstruction in Sec. 63.2 of subpart A of this part and 
reconstruction is commenced after January 14, 2003.
    (b) Subcategories with limited requirements. (1) A new or 
reconstructed stationary combustion turbine located at a major source 
which meets either of the following criteria does not have to meet the 
requirements of this subpart and of subpart A of this part except for 
the initial notification requirements of Sec. 63.6145(d):
    (i) The stationary combustion turbine is an emergency stationary 
combustion turbine; or
    (ii) The stationary combustion turbine is located on the North Slope 
of Alaska.
    (2) A stationary combustion turbine which burns landfill gas or 
digester gas equivalent to 10 percent or more of the gross heat input on 
an annual basis, or a stationary combustion turbine where gasified 
municipal solid waste (MSW) is used to generate 10 percent or more of 
the gross heat input on an annual basis does not have to meet the 
requirements of this subpart except for:
    (i) The initial notification requirements of Sec. 63.6145(d); and
    (ii) Additional monitoring and reporting requirements as provided in 
Sec. Sec. 63.6125(c) and 63.6150.
    (3) An existing, new, or reconstructed stationary combustion turbine 
with a rated peak power output of less than 1.0 megawatt (MW) at 
International Organization for Standardization (ISO) standard day 
conditions, which is located at a major source, does not have to meet 
the requirements of this subpart and of subpart A of this part. This 
determination applies to the capacities of individual combustion 
turbines, whether or not an aggregated group of combustion turbines has 
a common add-on air pollution control device. No initial notification is 
necessary, even if the unit appears to be subject to other requirements 
for initial notification. For example, a 0.75 MW emergency turbine would 
not have to submit an initial notification.
    (4) Existing stationary combustion turbines in all subcategories do 
not have to meet the requirements of this subpart and of subpart A of 
this part. No initial notification is necessary for any existing 
stationary combustion turbine, even if a new or reconstructed turbine in 
the same category would require an initial notification.
    (5) Combustion turbine engine test cells/stands do not have to meet 
the requirements of this subpart but may have to meet the requirements 
of subpart A of this part if subject to another subpart. No initial 
notification is necessary, even if the unit appears to be subject to 
other requirements for initial notification.



Sec. 63.6092  Are duct burners and waste heat recovery units covered
by subpart YYYY?

    No, duct burners and waste heat recovery units are considered steam 
generating units and are not covered under this subpart. In some cases, 
it may be difficult to separately monitor emissions from the turbine and 
duct burner, so sources are allowed to meet the required emission 
limitations with their duct burners in operation.



Sec. 63.6095  When do I have to comply with this subpart?

    (a) Affected sources. (1) If you start up a new or reconstructed 
stationary combustion turbine which is a lean premix oil-fired 
stationary combustion turbine or a diffusion flame oil-fired stationary 
combustion turbine as defined by this subpart on or before March 5, 
2004, you must comply with the emissions limitations and operating 
limitations in this subpart no later than March 5, 2004.
    (2) If you start up a new or reconstructed stationary combustion 
turbine which is a lean premix oil-fired stationary combustion turbine 
or a diffusion flame oil-fired stationary combustion turbine as defined 
by this subpart after March 5, 2004, you must comply with the emissions 
limitations and operating limitations in this subpart upon startup of 
your affected source.
    (b) Area sources that become major sources. If your new or 
reconstructed stationary combustion turbine is an area source that 
increases its emissions or its potential to emit such that it becomes a 
major source of HAP, it must be in compliance with any applicable 
requirements of this subpart when it becomes a major source.

[[Page 1065]]

    (c) You must meet the notification requirements in Sec. 63.6145 
according to the schedule in Sec. 63.6145 and in 40 CFR part 63, 
subpart A.
    (d) Stay of standards for gas-fired subcategories. If you start up a 
new or reconstructed stationary combustion turbine that is a lean premix 
gas-fired stationary combustion turbine or diffusion flame gas-fired 
stationary combustion turbine as defined by this subpart, you must 
comply with the Initial Notification requirements set forth in Sec. 
63.6145 but need not comply with any other requirement of this subpart 
until EPA takes final action to require compliance and publishes a 
document in the Federal Register.

                   Emission and Operating Limitations



Sec. 63.6100  What emission and operating limitations must I meet?

    For each new or reconstructed stationary combustion turbine which is 
a lean premix gas-fired stationary combustion turbine, a lean premix 
oil-fired stationary combustion turbine, a diffusion flame gas-fired 
stationary combustion turbine, or a diffusion flame oil-fired stationary 
combustion turbine as defined by this subpart, you must comply with the 
emission limitations and operating limitations in Table 1 and Table 2 of 
this subpart.

                     General Compliance Requirements



Sec. 63.6105  What are my general requirements for complying with
this subpart?

    (a) You must be in compliance with the emission limitations and 
operating limitations which apply to you at all times except during 
startup, shutdown, and malfunctions.
    (b) If you must comply with emission and operating limitations, you 
must operate and maintain your stationary combustion turbine, oxidation 
catalyst emission control device or other air pollution control 
equipment, and monitoring equipment in a manner consistent with good air 
pollution control practices for minimizing emissions at all times 
including during startup, shutdown, and malfunction.

               Testing and Initial Compliance Requirements



Sec. 63.6110  By what date must I conduct the initial performance 
tests or other initial compliance demonstrations?

    (a) You must conduct the initial performance tests or other initial 
compliance demonstrations in Table 4 of this subpart that apply to you 
within 180 calendar days after the compliance date that is specified for 
your stationary combustion turbine in Sec. 63.6095 and according to the 
provisions in Sec. 63.7(a)(2).
    (b) An owner or operator is not required to conduct an initial 
performance test to determine outlet formaldehyde concentration on units 
for which a performance test has been previously conducted, but the test 
must meet all of the conditions described in paragraphs (b)(1) through 
(b)(5) of this section.
    (1) The test must have been conducted using the same methods 
specified in this subpart, and these methods must have been followed 
correctly.
    (2) The test must not be older than 2 years.
    (3) The test must be reviewed and accepted by the Administrator.
    (4) Either no process or equipment changes must have been made since 
the test was performed, or the owner or operator must be able to 
demonstrate that the results of the performance test, with or without 
adjustments, reliably demonstrate compliance despite process or 
equipment changes.
    (5) The test must be conducted at any load condition within plus or 
minus 10 percent of 100 percent load.



Sec. 63.6115  When must I conduct subsequent performance tests?

    Subsequent performance tests must be performed on an annual basis as 
specified in Table 3 of this subpart.



Sec. 63.6120  What performance tests and other procedures must I use?

    (a) You must conduct each performance test in Table 3 of this 
subpart that applies to you.
    (b) Each performance test must be conducted according to the 
requirements of the General Provisions at

[[Page 1066]]

Sec. 63.7(e)(1) and under the specific conditions in Table 2 of this 
subpart.

during periods of startup, shutdown, or malfunction. Performance tests 
must be conducted at high load, defined as 100 percent plus or minus 10 
percent.
    (d) You must conduct three separate test runs for each performance 
test, and each test run must last at least 1 hour.
    (e) If your stationary combustion turbine is not equipped with an 
oxidation catalyst, you must petition the Administrator for operating 
limitations that you will monitor to demonstrate compliance with the 
formaldehyde emission limitation in Table 1. You must measure these 
operating parameters during the initial performance test and 
continuously monitor thereafter. Alternatively, you may petition the 
Administrator for approval of no additional operating limitations. If 
you submit a petition under this section, you must not conduct the 
initial performance test until after the petition has been approved or 
disapproved by the Administrator.
    (f) If your stationary combustion turbine is not equipped with an 
oxidation catalyst and you petition the Administrator for approval of 
additional operating limitations to demonstrate compliance with the 
formaldehyde emission limitation in Table 1, your petition must include 
the following information described in paragraphs (f)(1) through (5) of 
this section.
    (1) Identification of the specific parameters you propose to use as 
additional operating limitations;
    (2) A discussion of the relationship between these parameters and 
HAP emissions, identifying how HAP emissions change with changes in 
these parameters and how limitations on these parameters will serve to

equipment used in natural gas transmission includes the land, mains, 
valves, meters, boosters, regulators, storage vessels, dehydrators, 
compressors, and their driving units and appurtenances, and equipment 
used transporting gas from a production plant, delivery point of 
purchased gas, gathering system, storage area, or other wholesale source 
of gas to one or more distribution area(s).
    Natural gas transmission and storage facility means any grouping of 
equipment where natural gas is processed, compressed, or stored prior to 
entering

[[Page 1074]]

a pipeline to a local distribution company or (if there is no local 
distribution company) to a final end user. Examples of a facility for 
this source category are: an underground natural gas storage operation; 
or a natural gas compressor station that receives natural gas via 
pipeline, from an underground natural gas storage operation, or from a 
natural gas processing plant. The emission points associated with these 
phases include, but are not limited to, process vents. Processes that 
may have vents include, but are not limited to, dehydration and 
compressor station engines. Facility, for the purpose of a major source 
determination, means natural gas transmission and storage equipment that 
is located inside the boundaries of an individual surface site (as 
defined in this section) and is connected by ancillary equipment, such 
as gas flow lines or power lines. Equipment that is part of a facility 
will typically be located within close proximity to other equipment 
located at the same facility. Natural gas transmission and storage 
equipment or groupings of equipment located on different gas leases, 
mineral fee tracts, lease tracts, subsurface unit areas, surface fee 
tracts, or surface lease tracts shall not be considered part of the same 
facility.
    North Slope of Alaska means the area north of the Arctic Circle 
(latitude 66.5 degrees North).
    Oil and gas production facility as used in this subpart means any 
grouping of equipment where hydrocarbon liquids are processed, upgraded 
(i.e., remove impurities or other constituents to meet contract 
specifications), or stored prior to the point of custody transfer; or 
where natural gas is processed, upgraded, or stored prior to entering 
the natural gas transmission and storage source category. For purposes 
of a major source determination, facility (including a building, 
structure, or installation) means oil and natural gas production and 
processing equipment that is located within the boundaries of an 
individual surface site as defined in this section. Equipment that is 
part of a facility will typically be located within close proximity to 
other equipment located at the same facility. Pieces of production 
equipment or groupings of equipment located on different oil and gas 
leases, mineral fee tracts, lease tracts, subsurface or surface unit 
areas, surface fee tracts, surface lease tracts, or separate surface 
sites, whether or not connected by a road, waterway, power line or 
pipeline, shall not be considered part of the same facility. Examples of 
facilities in the oil and natural gas production source category 
include, but are not limited to, well sites, satellite tank batteries, 
central tank batteries, a compressor station that transports natural gas 
to a natural gas processing plant, and natural gas processing plants.
    Oxidation catalyst emission control device means an emission control 
device that incorporates catalytic oxidation to reduce CO emissions.
    Potential to emit means the maximum capacity of a stationary source 
to emit a pollutant under its physical and operational design. Any 
physical or operational limitation on the capacity of the stationary 
source to emit a pollutant, including air pollution control equipment 
and restrictions on hours of operation or on the type or amount of 
material combusted, stored, or processed, shall be treated as part of 
its design if the limitation or the effect it would have on emissions is 
federally enforceable. For oil and natural gas production facilities 
subject to subpart HH of this part, the potential to emit provisions in 
Sec. 63.760(a) may be used. For natural gas transmission and storage 
facilities subject to subpart HHH of this part, the maximum annual 
facility gas throughput for storage facilities may be determined 
according to Sec. 63.1270(a)(1) and the maximum annual throughput for 
transmission facilities may be determined according to Sec. 
63.1270(a)(2).
    Production field facility means those oil and gas production 
facilities located prior to the point of custody transfer.
    Production well means any hole drilled in the earth from which crude 
oil, condensate, or field natural gas is extracted.
    Regenerative/recuperative cycle stationary combustion turbine means 
any

[[Page 1075]]

stationary combustion turbine that recovers heat from the stationary 
combustion turbine exhaust gases using an exhaust heat exchanger to 
preheat the combustion air entering the combustion chamber of the 
stationary combustion turbine.
    Research or laboratory facility means any stationary source whose 
primary purpose is to conduct research and development into new 
processes and products, where such source is operated under the close 
supervision of technically trained personnel and is not engaged in the 
manufacture of products for commercial sale in commerce, except in a de 
minimis matter.
    Simple cycle stationary combustion turbine means any stationary 
combustion turbine that does not recover heat from the stationary 
combustion turbine exhaust gases.
    Stationary combustion turbine means all equipment, including but not 
limited to the turbine, the fuel, air, lubrication and exhaust gas 
systems, control systems (except emissions control equipment), and any 
ancillary components and sub-components comprising any simple cycle 
stationary combustion turbine, any regenerative/recuperative cycle 
stationary combustion turbine, the combustion turbine portion of any 
stationary cogeneration cycle combustion system, or the combustion 
turbine portion of any stationary combined cycle steam/electric 
generating system. Stationary means that the combustion turbine is not 
self propelled or intended to be propelled while performing its 
function. Stationary combustion turbines do not include turbines located 
at a research or laboratory facility, if research is conducted on the 
turbine itself and the turbine is not being used to power other 
applications at the research or laboratory facility.
    Storage vessel with the potential for flash emissions means any 
storage vessel that contains a hydrocarbon liquid with a stock tank gas-
to-oil ratio equal to or greater than 0.31 cubic meters per liter and an 
American Petroleum Institute gravity equal to or greater than 40 degrees 
and an actual annual average hydrocarbon liquid throughput equal to or 
greater than 79,500 liters per day. Flash emissions occur when dissolved 
hydrocarbons in the fluid evolve from solution when the fluid pressure 
is reduced.
    Surface site means any combination of one or more graded pad sites, 
gravel pad sites, foundations, platforms, or the immediate physical 
location upon which equipment is physically affixed.
