I. Background
On September 5, 1996 (61 FR 46906), and September 12, 1996 (61 FR
48208), the EPA published the Group I Polymers and Resins NESHAP and
the Group IV Polymers and Resins NESHAP, respectively. These
regulations were promulgated as subparts U and JJJ in 40 CFR part 63.
On November 25, 1996 the EPA published an Advance Notice of Proposed
Rulemaking (ANPR) (61 FR 59849) informing the public of the intent to
propose amendments to the recently promulgated Group I Polymers and
Resins NESHAP and Group IV Polymers and Resins NESHAP.
Although it is anticipated that the amendments to the Group I and
Group IV Polymers and Resins NESHAP will be published simultaneously
with this Direct Final Rule, it is not likely that those amendments
will be finalized prior to Spring 1999. For that reason, the EPA is
publishing this direct final rule, which, as long as no relevant
adverse comments are received by April 8, 1999, will become effective
immediately (without further rulemaking action) on May 10, 1999. If
adverse comments are received on one or more of the distinct
amendments, paragraphs, or sections in this rulemaking, the EPA will
publish a timely withdrawal in the Federal Register withdrawing the
specific provisions that are the subject of adverse comment. Any
provision in today's rulemaking that does not receive adverse comment
will become effective on the date set out above, notwithstanding any
adverse comment on any other distinct provision in today's rulemaking.
The EPA is publishing this rule as a direct final rule because the EPA
views this as a noncontroversial amendment and anticipates no adverse
comments. However, should adverse comments be received on a distinct
provision in this rulemaking, the EPA will publish a timely withdrawal
in the Federal Register indicating which provisions will become
effective and which provisions are being withdrawn. If part or all of
this direct final rule is withdrawn, all public comments received will
be addressed in a subsequent final rule based on today's proposal. The
nature of the changes contained in today's direct final rule are such
that it will be of great benefit to industry and the States for these
changes to become effective sooner rather than later, as will be
described in more detail below.
II. Summary of and Rationale for Revisions
A. Correction to Equation in Sec. 60.564
The first correction that this direct final rule makes is to an
equation in Sec. 60.564 of the Standards for Performance for Volatile
Organic Compound (VOC) Emissions from the Polymer Manufacturing
Industry (subpart DDD). The equation in Sec. 60.564(h) is being
corrected so that the emission rate determined by the equation is
actually in kg total organic compound (TOC) per Mg product. During work
on the other changes contained in this direct final rule, the EPA
became aware that the promulgated version of the equation in
Sec. 60.564(h) misplaced the conversion factor between kilograms and
megagrams, resulting in an erroneous production rate of polymer. The
corrected equation results in the correct units for the emission rate
of TOC (i.e., kg TOC/Mg product).
B. Modification of Compressors
The remainder of the changes contained in this Direct Final Rule
are either in the Group I Polymers and Resins NESHAP, in the Group IV
Polymers and Resins NESHAP, or both. The NESHAP for Group I Polymers
and Resins and for Group IV Polymers and Resins omitted a provision
that is contained in the Hazardous Organics NESHAP (HON), 40 CFR part
63, subpart H, on which these provisions are based. This provision, as
added at Secs. 63.481(d)(1)(iv) and 63.1311(d)(1)(iv), specifies
another criterion to be considered in determining the compliance data
for compressors.
C. Compliance Extension for Compressors
This direct final rule includes new language in Sec. 63.1311(d)(4),
as Sec. 63.1311(d)(4)(ii), which corrects an error in the promulgated
paragraph. At promulgation, this paragraph identified two situations in
which a compliance extension could be requested. These situations are
if the compressor must be replaced or the distance piece must be
recast. A third situation (which was included in subpart U, as
Sec. 63.481(d)(4)(iii)) should have been included, which is if a design
modification is required to connect the compressor to a closed-vent or
recovery system. As part of adding this third situation, the paragraph
was reorganized to improve the clarity.
D. Changes to the 20 ppmv Organic HAP Outlet Concentration Option for
Group 1 Continuous Process Vents
Several changes have been made related to the 20 ppmv organic HAP
outlet concentration compliance option for Group 1 continuous process
vents subject to Secs. 63.485 or 63.1315, which reference to the HON
process vent requirements in Secs. 63.113 through 63.118. The outlet
concentration limit of 20 ppmv represents the performance limit of the
control technology (see 61 FR 43698, August 26, 1996, pg. 43704 for
more details). When determining compliance with the 20 ppmv outlet
concentration standard under Secs. 63.485 or 63.1315, the promulgated
rule required that the outlet concentration be corrected to 3 percent
oxygen. The changes made in this direct final rule only require a
correction to 3 percent oxygen if supplemental combustion air is used
to combust the emissions. A definition of supplemental combustion air
has also been added. Finally, similar language has been added as part
of adding a 20 ppmv outlet concentration compliance option to the
aggregate batch vent stream provisions. The addition of a 20 ppmv
organic HAP outlet concentration compliance option for aggregate batch
vent streams is discussed later in this preamble.
The Polymers and Resins I and IV rules refer directly to the HON
for control of continuous process vents subject to Secs. 63.485 or
63.1315. Both rules (Polymers and Resins I and IV) refer to, and are
based on, the HON process vent requirements for aggregate batch vent
streams. Under the HON, the correction to 3 percent oxygen is
[[Page 11538]]
required for purposes of demonstrating compliance with the 20 ppmv
outlet concentration standard. The purpose of correcting an outlet
concentration to 3 percent oxygen is to prevent owners or operators
from diluting streams to meet the 20 ppmv outlet concentration
standard; dilution as a means of complying with a part 63 standard is
prohibited by the General Provisions (see Sec. 63.4(b)). The value of 3
percent originates from good engineering practices. Synthetic Organic
Chemical Manufacturing (SOCMI) facilities subject to the HON do not
typically have high oxygen, low VOC/HAP concentration streams; streams
from SOCMI unit operations are typically low oxygen, high VOC/HAP
concentration streams that require supplemental combustion air for
purposes of combusting the emissions. For such oxygen deficient vent
streams, adding the proper amount of supplemental combustion air would
result in the outlet stream containing approximately 3 percent oxygen.
The HON continuous process vent provisions are written assuming that
continuous process vents will require supplemental combustion air when
they are combusted, and therefore requires a 3 percent oxygen
correction for all continuous process vents to prevent dilution.
The concept of requiring the correction to 3 percent oxygen only
when supplemental combustion air is used, as is done in this direct
final rule has a precedent in the Polymer Manufacturing New Source
Performance Standards (NSPS). During development of the Polymer
Manufacturing NSPS, the issue of requiring a high oxygen, low VOC
concentration stream to correct the outlet concentration to 3 percent
oxygen was raised. Commenters made the point that an oxygen correction
may be appropriate for oxygen deficient streams where supplemental
combustion air has been added in order to ensure combustion of the
emissions, but such a correction is not appropriate for high oxygen,
low VOC concentration streams. Review of this concern revealed that
requiring an oxygen correction for processes with inherently high
oxygen concentration streams would amount to taking away the compliance
option of reaching the 20 ppmv outlet concentration. Because the
combination of low VOC/HAP concentration and technology limitations of
control devices sometimes make it impossible to achieve a 98 percent
emission reduction, the 20 ppmv outlet concentration may be necessary
for some streams. For the group of streams that cannot demonstrate a 98
percent emission reduction, failure to address this issue would make it
impossible for owners or operators to demonstrate compliance. As a
result of these considerations, the final rule for the Polymer
Manufacturing NSPS was changed to require a correction to 3 percent
oxygen only if supplemental combustion air was used to combust the
emissions.
The EPA has determined that a similar amendment is appropriate for
the Polymers and Resins I and IV rules. Accordingly, the EPA has
conducted a technical analysis to provide additional support for this
decision. The technical analysis is documented in a memorandum to the
project docket. The analysis found that an oxygen correction had not
been applied to the data used to develop the 20 ppmv outlet
concentration standard. Therefore, the 20 ppmv value is appropriate as
an outlet concentration standard for uncorrected outlet concentrations
(i.e., streams that do not require supplemental combustion air). This
amendment does not alter the use of the 20 ppmv value compliance option
where supplemental combustion air is used, provided, as with the
promulgated rule, a 3 percent oxygen correction is made. Because the
proper addition of supplemental combustion air should result in an
oxygen outlet concentration of approximately 3 percent, requiring a
correction to 3 percent oxygen should not change the outlet
concentration of VOC/HAP significantly, and will ensure that the 20
ppmv outlet concentration standard will not be met through dilution.
In conclusion, the Polymers and Resins I and IV rules regulate
industries (i.e., elastomer producers and thermoplastic producers,
respectively) that may contain high oxygen, low VOC/HAP concentration
process vent streams (e.g., streams that do not require supplemental
combustion air such as vent streams from dryers), as well as low oxygen
concentration streams. Therefore, for the same reason that a change was
made to the Polymer Manufacturing NSPS and based on the support
provided by the technical analysis described above, a provision to
require an outlet concentration oxygen correction only when
supplemental combustion air is used has been added to the continuous
process vent provisions (i.e., Secs. 63.485 and 63.1315) for the
Polymers and Resins I and IV rules. Similar changes have been made to
the aggregate batch vent stream provisions, as part of adding a 20 ppmv
outlet concentration compliance option to those provisions.
Definitions of ``supplemental combustion air'' and ``combustion
device burner''. The EPA has added a definition of supplemental
combustion air that reads as follows:
Supplemental combustion air 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 combustion air. Air
required to operate combustion device burner(s) is not considered
supplemental combustion air.
In adding this definition, the EPA is distinguishing supplemental
combustion air from dilution air and from air required to operate the
combustion device burner(s). The second sentence of the definition
clarifies that a vent stream can contain air that is not considered to
be ``supplemental combustion air,'' as long as the air is part of the
vent stream prior to the vent stream leaving the unit operation. This
clarification ensures that processes operating at ambient or near
ambient oxygen levels are not considered to be using supplemental
combustion air. An example of this kind of process is a dryer, where
very high flow rates of ambient air are heated and blown over/through/
around polymer that is being dried and very low levels of HAP are
picked up as part of the drying process. The third sentence of the
definition clarifies that air used to operate combustion device
burner(s) is not considered supplemental combustion air. Failure to
include this clarification could allow the interpretation that every
combustion device uses supplemental combustion air. To further clarify
the meaning of this third sentence, the EPA has added a definition of
combustion device burner that reads as follows:
Combustion device burner means a device designed to mix and
ignite fuel and air to provide a flame to heat and oxidize waste
organic vapors in a combustion device.
The EPA is not amending the reference in these rules to the General
Provisions prohibition against dilution to prevent compliance through
dilution. Section 63.4(b), Circumvention, discusses the prohibition
against dilution, and specifically prohibits ``the use of diluents to
achieve compliance with a relevant standard based on the concentration
of a pollutant in the effluent discharged to the atmosphere.''
E. Addition of New PET Compliance Options
Section 63.1316(b), which specifies control requirements for
certain continuous process vents at
[[Page 11539]]
poly(ethylene terephthlate) (PET) affected sources, has been amended to
add compliance options based on the use of combustion devices;
combustion controls allowed in other sections of this rule assure
highly efficient reduction of emissions. The changes to Sec. 63.1316(b)
contained in this direct final rule will provide the same option for
owners or operators of continuous dimethyl terephthalate (DMT) PET
processes and continuous terephthalic acid (TPA) PET processes.
The need for these changes became apparent when a request was
received from a company (Docket A-92-45, item VI-A-12) that wanted to
comply with the continuous process vent requirements of Sec. 63.1316(b)
using combustion controls. In one situation, the company is controlling
continuous process vents from a continuous DMT PET process with a
boiler that acheives a 99.99 percent emission reduction, based on
emission tests conducted by the EPA. In this case, emissions are
reduced to a much greater extent than the promulgated rule requires,
and wastewater streams from the process are also eliminated. In the
second case, the company is controlling continuous process vents from a
continuous TPA PET process with a catalytic incinerator that achieves
98 percent emission reduction. Wastewater discharges from the process
are eliminated in the second case, as well. Analysis shows that
emissions are reduced to a greater extent with the control systems
described above than would be achieved through compliance with the
separate, promulgated process vent and wastewater provisions (Docket A-
92-45, Item VI-B-22).
Therefore, the EPA believes that the same combustion control
options (including, but not limited to, thermal incinerators, catalytic
incinerators, boilers, or process heaters) that are allowed elsewhere
in this rule (for example in Sec. 63.1316(c) for polystyrene affected
sources) should be provided in Sec. 63.1316(b), since these combustion
devices are highly efficient techniques for reducing organic HAP
emissions. Also, the application of these combustion techniques allows
innovative control strategies, including pollution prevention measures
such as those described above, which might otherwise be discouraged
under the promulgated rule.
F. Clarification of the Term ``Primary Condenser''
In both the Group I and the Group IV Polymers and Resins NESHAP,
this Direct Final Rule is amending language in order to clarify what
these rules mean by the term ``primary condenser.'' This change is
being made in Secs. 63.488(a)(2) and 63.1323(a)(2). There was some
confusion over the language contained in those paragraphs at
promulgation (partially due to an inconsistency between the promulgated
preambles and the promulgated rules), and with the new language the EPA
hopes to eliminate any such confusion. As Secs. 63.488(a)(2) and
63.1323(a)(2) should make clear, a primary condenser can be a condenser
operating as a reflux condenser on either a reactor or distillation
column, or can be a condenser operating on a stripper or distillation
operation to recover monomer, reaction products, by-products, or
solvent.
G. References to Test Methods for the Polymers and Resins I Rule
This direct final rule is also adding references to the Test
Methods for the Polymers and Resins I Rule, which were finalized on
March 17, 1997 (62 FR 12546), and are contained in Appendix A of part
63. The newly added references to those Test Methods are contained in
Secs. 63.495(b)(3) and (e) and 63.505(e)(1)(ii).
H. Cross-Reference and Grammatical Corrections in Emissions Averaging
Provisions
This direct final rule is making cross-reference and grammatical
corrections (e.g., changing ``can'' to ``may,'' where appropriate)
throughout Secs. 63.503 and 63.1332. No substantive changes have been
made to either of those two sections.
I. Removal of Reference to Obsolete HON Table
In Secs. 63.506(e)(4)(ii)(H)(1) and 63.1335(e)(4)(ii)(L)(1), a
reference to Table 14b of subpart G has been removed, because that
table was removed in the promulgated amendments to the HON.
J. Clarification to Group 1 Storage Vessel Requirements in Subpart JJJ
A new paragraph is being introduced with this direct final rule
(Sec. 63.1314(b)(3)), in order to clarify that, for all storage vessels
that are not described in Sec. 63.1314(b)(1) or (2), the owner or
operator must control emissions to the level specified in Sec. 63.119.
K. Process Vent Provisions for Affected Sources Producing Acrylonitrile
Styrene Acrylate Resin/Alpha Methyl Styrene Acrylonitrile Resin (ASA/
AMSAN)
This direct final rule includes a new paragraph at Sec. 63.1315(e),
which states the special control level for process vents at affected
sources that produce acrylonitrile styrene acrylate resin (ASA) or
alpha methyl styrene acrylonitrile resin (AMSAN). In addition, a
reference to the new provisions in Sec. 63.1315(e) has been added in
Sec. 63.1321, as Sec. 63.1321(d).
L. Exemptions from Wastewater Provisions in Subpart JJJ
This direct final rule adds two paragraphs to Sec. 63.1330, both of
which act as exemptions from certain wastewater provisions in that
section. The new paragraphs are Sec. 63.1330(d) and (e), and pertain to
affected sources producing ASA/AMSAN and affected sources producing
polystyrene using a continuous or batch process.
M. Amendments to Tables 3 and 5 of Subpart JJJ
This direct final rule makes corrections and clarifications to both
Tables 3 and 5. In the amended Table 5, the entry for Group 1 storage
vessels associated with the production of styrene acrylonitrile resin
(SAN) was clarified and footnote ``d'' was added. Because there are
different control levels for different sets of storage vessels, the
promulgated table appeared to present overlapping capacity and vapor
pressure criteria, which was not the EPA's intent.
III. Impacts
The changes contained in this direct final rule are corrections and
clarifications of the EPA's intent at the promulgation of subparts U
and JJJ, and will not affect the estimated emissions reduction or the
control cost for these rules. These clarifications and corrections
should make it easier for owners and operators of affected sources, and
for local and State authorities, to understand and implement the
requirements found in subparts U and JJJ.
IV. Administrative Requirements
A. Docket
The docket is an organized and complete file of all the information
considered by the EPA in the development of this rulemaking. The docket
is a dynamic file, because material is added throughout the rulemaking
development. The docketing system is intended to allow members of the
public and industries involved to readily identify and locate documents
so that they can effectively participate in the rulemaking process.
Along with the proposed and promulgated standards and their preambles,
the contents of the docket will serve as the
[[Page 11540]]
record in the case of judicial review. (See section 307(d)(7)(A) of the
Act.)
B. Executive Order 12866
Under Executive Order 12866 (58 FR 51735, October 4, 1993), the EPA
must submit to the Office of Management and Budget (OMB) for review
significant regulatory actions. The Executive Order defines
``significant regulatory action'' as one that OMB determines is likely
to result in a rule that may:
(1) Have an annual effect on the economy of $100 million or more or
adversely affect in a material way the economy, a sector of the
economy, productivity, competition, jobs, the environment, public
health or safety, or State, local, or Tribal governments or
communities;
(2) Create a serious inconsistency or otherwise interfere with an
action taken or planned by another agency;
(3) Materially alter the budgetary impact of entitlements, grants,
user fees, or loan programs, or the rights and obligations of
recipients thereof; or
(4) Raise novel legal or policy issues arising out of legal
mandates, the President's priorities, or the principles set forth in
the Executive Order.
It has been determined that this Direct Final Rule does not qualify
as a ``significant regulatory action'' under the terms of Executive
Order 12866 and, therefore, is not subject to review by the Office of
Management and Budget.
C. Executive Order 12875: Enhancing Intergovernmental Partnerships
Under Executive Order 12875, the EPA may not issue a regulation
that is not required by statute and that creates a mandate upon a
State, local, or tribal government, unless the Federal government
provides the funds necessary to pay the direct compliance costs
incurred by those governments, or EPA consults with those governments.
If EPA complies by consulting, Executive Order 12875 requires EPA to
provide to the Office of Management and Budget a description of the
extent of EPA's prior consultation with representatives of affected
State, local, and tribal governments, the nature of their concerns,
copies of any written communications from the governments, and a
statement supporting the need to issue the regulation. In addition,
Executive Order 12875 requires EPA to develop an effective process
permitting elected officials and other representatives of State, local,
and tribal governments ``to provide meaningful and timely input in the
development of regulatory proposals containing significant unfunded
mandates.''
Today's direct final rule does not create a mandate on State,
local, or tribal governments. This direct final rule does not impose
any enforceable duties on these entities. Accordingly, the requirements
of section 1(a) of Executive Order 12875 do not apply to this direct
final rule.
D. Executive Order 13084: Consultation and Coordination With Indian
Tribal Governments
Under Executive Order 13084, the EPA may not issue a regulation
that is not required by statute, that significantly or uniquely affects
the communities of Indian tribal governments, and that imposes
substantial direct compliance costs on those communities, unless the
Federal government provides the funds necessary to pay the direct
compliance costs incurred by the tribal governments, or EPA consults
with those governments. If EPA complies by consulting, Executive Order
13084 requires EPA to provide to the Office of Management and Budget,
in a separately identified section of the preamble to the rule, a
description of the extent of EPA's prior consultation with
representatives of affected tribal governments, a summary of the nature
of their concerns, and a statement supporting the need to issue the
regulation. In addition, Executive Order 13084 requires the EPA to
develop an effective process permitting elected and other
representatives of Indian tribal governments ``to provide meaningful
and timely input in the development of regulatory policies on matters
that significantly or uniquely affect their communities.''
This direct final rule does not impose any duties or compliance
costs on Indian tribal governments. Further, the direct final rule
provided herein does not significantly alter the control standards
imposed by subpart U or subpart JJJ for any source, including any that
may affect communities of the Indian tribal governments. Hence, today's
direct final rule does not significantly or uniquely affect the
communities of Indian tribal governments. Accordingly, the requirements
of section 3(b) of Executive Order 13084 do not apply to this direct
final rule.
E. Unfunded Mandates Reform Act
Section 202 of the Unfunded Mandates Reform Act of 1995 (UMRA),
requires that the Agency prepare a budgetary impact statement before
promulgating a rule that includes a Federal mandate that may result in
expenditure by State, local, and tribal governments, in the aggregate,
or by the private sector, of more than $100 million in any one year.
Section 203 requires the Agency to establish a plan for obtaining input
from and informing, educating, and advising any small governments that
may be significantly or uniquely affected by the rule.
The EPA has determined that this direct final rule does not include
a Federal mandate that may result in estimated costs of, in the
aggregate, $100 million or more to either State, local, or tribal
governments in the aggregate, or to the private sector, and that this
direct final rule does not significantly or uniquely impact small
governments, because it contains no requirements that apply to such
governments or impose obligations upon them. The EPA has not prepared a
budgetary impact statement or specifically addressed the selection of
the least costly, most cost-effective, or least burdensome alternative.
In addition, because small governments will not be significantly or
uniquely affected by this rule, the Agency is not required to develop a
plan with regard to small governments. Therefore, the requirements of
the Unfunded Mandates Act do not apply to this direct final rule.
F. Regulatory Flexibility
The Regulatory Flexibility Act (RFA) generally requires an agency
to conduct a regulatory flexibility analysis of any rule subject to
notice and comment rulemaking requirements unless the agency certifies
that the rule will not have a significant economic impact on a
substantial number of small entities. Small entities include small
business, small not-for-profit enterprises, and small governmental
jurisdictions. This direct final rule would not have a significant
impact on a substantial number of small entities, because it clarifies
and makes corrections to the promulgated versions of the Group I and IV
Polymers and Resins NESHAP, but imposes no additional regulatory
requirements on owners or operators of affected sources.
G. Paperwork Reduction Act
For both the Group I and Group IV Polymers and Resins NESHAP, the
information collection requirements (ICRs) were submitted to the OMB
under the Paperwork Reduction Act. At promulgation, OMB had already
approved the ICRs for the Group IV Polymers and Resins NESHAP and
assigned those standards the OMB control number 2060-0351.
Subsequently, the OMB approved the ICRs for the Group I Polymers and
Resins NESHAP, and on July 15, 1997 (62 FR 37720) the OMB control
number
[[Page 11541]]
2060-0356 was assigned to the Group I Polymers and Resins NESHAP. An
Agency may not conduct or sponsor, and a person is not required to
respond to, a collection of information unless it displays a currently
valid OMB control number. The OMB control numbers for the EPA's
regulations are listed in 40 CFR part 9 and 48 CFR Chapter 15. The EPA
has amended 40 CFR part 9, Sec. 9.1, to indicate the ICRs contained in
the Group I and IV Polymers and Resins NESHAP.
The amendments to the NESHAP contained in this direct final rule
should have no impact on the information collection burden estimates
made previously. Therefore, the ICRs have not been revised.
H. Applicability of Executive Order 13045
Executive Order 13045: ``Protection of Children from Environmental
Health Risks and Safety Risks'' (62 FR 19885, April 23, 1997) applies
to any rule that (1) is determined to be ``economically significant''
as defined under Executive Order 12866, and (2) concerns an
environmental health or safety risk that the EPA has reason to believe
may have a disproportionate effect on children. If the regulatory
action meets both criteria, the Agency must evaluate the environmental
health or safety effects of the planned rule on children, and explain
why the planned regulation is preferable to other potentially effective
and reasonably feasible alternatives considered by the Agency.
The EPA interprets Executive Order 13045 as applying only to those
regulatory actions that are based on health or safety risks, such that
the analysis required under section 5-501 of the Order has the
potential to influence the regulation. This direct final rule is not
subject to Executive Order 13045 because it does not establish an
environmental standard intended to mitigate health or safety risks.
I. Submission to Congress and the Comptroller General
The Congressional Review Act, 5 U.S.C. 801 et seq., added by the
Small Business Regulatory Enforcement Fairness Act of 1996, generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report, which includes a copy of the rule,
to each House of the Congress and to the Comptroller General of the
United States. The EPA will submit a report containing this direct
final rule and other required information to the U.S. Senate, the U.S.
House of Representatives, and the Comptroller General of the United
States prior to publication of this direct final rule in the Federal
Register. A major rule cannot take effect until 60 days after it is
published in the Federal Register. This direct final rule is not a
``major rule'' as defined by 5 U.S.C. Sec. 804(2).
J. National Technology Transfer and Advancement Act
Section 12(d) of the National Technology Transfer and Advancement
Act of 1995 (NTTAA) directs all Federal agencies to use voluntary
consensus standards instead of government-unique standards in their
regulatory activities unless to do so would be inconsistent with
applicable law or otherwise impractical. Voluntary consensus standards
are technical standards (e.g., material specifications, test methods,
sampling and analytical procedures, business practices, etc.) that are
developed or adopted by one or more voluntary consensus standards
bodies. Examples of organizations generally regarded as voluntary
consensus standards bodies include the American Society for Testing and
Materials (ASTM), the National Fire Protection Association (NFPA), and
the Society of Automotive Engineers (SAE). The NTTAA requires Federal
agencies like EPA to provide Congress, through OMB, with explanations
when an agency decides not to use available and applicable voluntary
consensus standards.
This action does not involve the proposal of any new technical
standards. The EPA welcomes comments on this aspect of the Direct Final
Rule and, specifically, invites the public to identify potentially-
applicable voluntary consensus standards and to explain why such
standards should be used in this regulation.
As part of a larger effort, the EPA is undertaking a project to
cross-reference existing voluntary consensus standards on testing,
sampling, and analysis with current and future EPA test methods. When
completed, this project will assist the EPA in identifying potentially-
applicable voluntary consensus standards which can then be evaluated
for equivalency and applicability in determining compliance with future
regulations.

million by volume, whichever is less stringent, on a continuous basis
using a control device. For purposes of complying with the 20 parts per
million by volume outlet concentration standard, the outlet
concentration shall be calculated on a dry basis. When a combustion
device is used for purposes of complying with the 20 parts per million
by volume outlet concentration standard, the concentration shall be
corrected to 3 percent oxygen if supplemental combustion air is used to
combust the emissions. If supplemental combustion air is not used, a
correction to 3 percent oxygen is not required.

(m)(5)(i), (m)(5)(ii), (m)(5)(iii), and (m)(5)(iv), to read as follows:
Sec. 63.503 Emissions averaging provisions.
(a) This section applies to owners or operators of existing
affected sources who seek to comply with Sec. 63.483(b) by using
emissions averaging rather than following the provisions of
Secs. 63.484, 63.485, 63.486, 63.494, and 63.501.
* * * * *
(2) Compliance with the provisions of this section may be based on
either organic HAP or TOC.
(3) For the purposes of the provisions in this section, whenever
Method 18, 40 CFR part 60, appendix A, is specified within the
paragraphs of this section or is specified by reference through
provisions outside this section, Method 18 or Method 25A, 40 CFR part
60, appendix A, may be used. The use of Method 25A, 40 CFR part 60,
appendix A, shall conform with the requirements in paragraphs (a)(3)(i)
and (a)(3)(ii) of this section.
(i) The organic HAP used as the calibration gas for Method 25A, 40
CFR part 60, appendix A, shall be the single organic HAP representing
the largest percent by volume of the emissions.
(ii) The use of Method 25A, 40 CFR part 60, appendix A, is
acceptable if the response from the high-level calibration gas is at
least 20 times the standard deviation of the response from the zero
calibration gas when the instrument is zeroed on the most sensitive
scale.
* * * * *
(c) Paragraphs (c)(1) through (c)(4) of this section describe the
emission points that may be used to generate emissions averaging
credits if control was applied after November 15, 1990 and if
sufficient information is available to determine the appropriate value
of credits for the emission point. Paragraph (c)(5) of this section
discusses the use of pollution prevention in generating emissions
averaging credits.
* * * * *
(2) Storage vessels, continuous front-end process vents, and
process wastewater steams that are determined to be Group 1 emission
points and that are controlled by a technology that the Administrator
or permitting authority agrees has a higher nominal efficiency than the
reference control technology. Information on the nominal efficiencies
for such technologies shall be submitted and approved as provided in
paragraph (i) of this section.
* * * * *
(5) * * *
(i) For a Group 1 storage vessel, batch front-end process vent,
aggregate batch vent stream, continuous front-end process vent, or
process wastewater stream, the pollution prevention measure shall
reduce emissions more than if the reference control technology or
standard had been applied to the emission point instead of the
pollution prevention measure, except as provided in paragraph
(c)(5)(ii) of this section.
(ii) If a pollution prevention measure is used in conjunction with
other controls for a Group 1 storage vessel, batch front-end process
vent, aggregate batch vent stream, continuous front-end process vent,
or process wastewater stream, the pollution prevention measure alone
does not have to reduce emissions more than the reference control
technology or standard, but the combination of the pollution prevention
measure and other controls shall reduce emissions more than if the
applicable reference control technology or standard had been applied
instead of the pollution prevention measure.
(d) * * *
(5) Emission points controlled to comply with a State or Federal
rule other than this subpart cannot be used to generate credits, unless
the level of control has been increased after November 15, 1990 to a
level above what is required by the other State or Federal rule. Only
the control above what is required by the other State or Federal rule
will be credited. However, if an emission point has been used to
generate emissions averaging credit in an approved emissions average,
and the emission point is subsequently made subject to a State or
Federal rule other than this subpart, the emission point may continue
to generate emissions averaging credit for the purpose of complying
with the previously approved emissions average.
(e) * * *
(3) * * *
(ii) The initial demonstration in the Emissions Averaging Plan or
operating permit application that credit-generating emission points
will be capable of generating sufficient credits to offset the debits
from the debit-generating emission points shall be made under
representative operating conditions. After the compliance date, actual
operating data will be used for all debit and credit calculations.
* * * * *
(5) Record and report quarterly and annual credits and debits in
the Periodic
[[Page 11544]]
Reports as specified in Sec. 63.506(e)(6). Every fourth Periodic Report
shall include a certification of compliance with the emissions
averaging provisions as required by Sec. 63.506(e)(6)(x)(C)(2).
* * * * *
(g) * * *
(1) Source-wide debits shall be calculated using Equation 33.
Debits and all terms of the equation are in units of megagrams per
month (Mg/month):
[GRAPHIC] [TIFF OMITTED] TR09MR99.005
Where:
ECFEPViACTUAL = Emissions from each Group 1 continuous
front-end process vent i that is uncontrolled or is controlled to a
level less stringent than the applicable reference control
technology. ECFEPViACTUAL is calculated according to
paragraph (g)(2)(iii) of this section.
(0.02)ECFEPViu = Emissions from each Group 1 continuous
front-end process vent i if the applicable reference control
technology had been applied to the uncontrolled emissions.
ECFEPViu is calculated according to paragraph (g)(2)(ii)
of this section.
ESiACTUAL = Emissions from each Group 1 storage vessel i
that is uncontrolled or is controlled to a level less stringent than
the applicable reference control technology or standard.
ESiACTUAL is calculated according to paragraph (g)(3) of
this section.
(0.05)ESiu = Emissions from each Group 1 storage vessel i
if the applicable reference control technology or standard had been
applied to the uncontrolled emissions. ESiu is calculated
according to paragraph (g)(3) of this section.
EBEPACTUAL = Emissions from back-end process operations
that do not meet the residual organic HAP limits in Sec. 63.494.
EBEPACTUAL is calculated according to paragraph (g)(4)(i)
of this section.
EBEPc = Emissions from back-end process operations if the
residual organic HAP limits in Sec. 63.494(a) were met.
EBEPc is calculated according to paragraph (g)(4)(ii) of
this section.
EWWiACTUAL = Emissions from each Group 1 wastewater
stream i that is uncontrolled or is controlled to a level less
stringent than the applicable reference control technology.
EWWiACTUAL is calculated according to paragraph (g)(5) of
this section.
EWWic = Emissions from each Group 1 wastewater stream i
if the reference control technology had been applied to the
uncontrolled emissions. EWWic is calculated according to
paragraph (g)(5) of this section.
EBFEPViACTUAL = Emissions from each Group 1 batch front-
end process vent stream i that is uncontrolled or is controlled to a
level less stringent than the applicable standard.
EBFEPViACTUAL is calculated according to paragraph
(g)(6)(ii) of this section.
(0.1) EBFEPViu = Emissions from each Group 1 batch front-
end process vent i if the applicable standard had been applied to
the uncontrolled emissions. EBFEPViu is calculated
according to paragraph (g)(6)(i) of this section.
EABViACTUAL = Emissions from each Group 1 aggregate batch
vent stream i that is uncontrolled or is controlled to a level less
stringent than the applicable standard. EABViACTUAL is
calculated according to paragraph (g)(7)(iii) of this section.
(0.1) EABViu = Emissions from each Group 1 aggregate
batch vent stream i if the applicable standard had been applied to
the uncontrolled emissions. EABViu is calculated
according to paragraph (g)(7)(ii) of this section.
n = The number of emission points being included in the emissions
average.

(ii) * * *
(A) The values of Q and Cj shall be determined during a
performance test conducted under representative operating conditions.
The values of Q and Cj shall be established in the
Notification of Compliance Status and shall be updated as provided in
paragraph (g)(2)(ii)(B) of this section.
* * * * *
(iii) * * *
* * * * *
(B) * * *
(1) The percent reduction shall be measured according to the
procedures in Sec. 63.116 if a combustion control device is used. For a
flare meeting the criteria in Sec. 63.116(a), or a boiler or process
heater meeting the criteria in Sec. 63.116(b), the percent reduction
shall be 98 percent. If a noncombustion control device is used, percent
reduction shall be demonstrated by a performance test at the inlet and
outlet of the device, or, if testing is not feasible, by a control
design evaluation and documented engineering calculations.
(2) For determining debits from Group 1 continuous front-end
process vents, product recovery devices shall not be considered control
devices and cannot be assigned a percent reduction in calculating
ECFEPViACTUAL. The sampling site for measurement of
uncontrolled emissions is after the final product recovery device.
However, as provided in Sec. 63.113(a)(3), a Group 1 continuous front-
end process vent may add sufficient product recovery to raise the TRE
index value above 1.0, thereby becoming a Group 2 continuous front-end
process vent. Such a continuous front-end process vent would not be a
Group 1 continuous front-end process vent and would, therefore, not be
included in determining debits under this paragraph.
* * * * *
(3) Emissions from storage vessels shall be calculated using the
procedures specified in Sec. 63.150(g)(3).
* * * * *
(5) Emissions from wastewater shall be calculated using the
procedures specified in Sec. 63.150(g)(5).
* * * * *
(7) * * *
(ii) * * *
(A) The values of Q and Cj shall be determined during a
performance test conducted under representative operating conditions.
The values of Q and Cj shall be established in the
Notification of Compliance Status and shall be updated as provided in
paragraph (g)(7)(ii)(B) of this section.

(h) * * *
(1) Source-wide credits shall be calculated using Equation 41.
Credits and all terms of the equation are in units of Mg/month, and the
baseline date is November 15, 1990:
[[Page 11545]]
[GRAPHIC] [TIFF OMITTED] TR09MR99.006
Where:
D = Discount factor = 0.9 for all credit generating emission points,
except those controlled by a pollution prevention measure; discount
factor = 1.0 for each credit generating emission point controlled by
a pollution prevention measure (i.e., no discount provided).
ECFEPV1iACTUAL = Emissions for each Group 1 continuous
front-end process vent i that is controlled to a level more
stringent than the reference control technology.
ECFEPV1iACTUAL is calculated according to paragraph
(h)(2)(ii) of this section.
(0.02)ECFEPV1iu = Emissions from each Group 1 continuous
front-end process vent i if the reference control technology had
been applied to the uncontrolled emissions. ECFEPV1iu is
calculated according to paragraph (h)(2)(i) of this section.
ECFEPV2iACTUAL = Emissions from each Group 2 continuous
front-end process vent i that is controlled.
ECFEPV2iACTUAL is calculated according to paragraph
(h)(2)(iii) of this section.

(1) In those cases where the owner or operator is seeking
permission to take credit for use of a control technology that is
different in use or design from the reference control technology, and
the different control technology will be used in more than three
applications at a single plant-site, the owner or operator shall submit
the information specified in paragraphs (i)(1)(i) through (i)(1)(iv) of

efficiency. The Administrator reserves the right to request specific
data in addition to the items listed in paragraph (i)(1) of this
section.
(3) The Administrator shall determine within 120 days of the
submittal of sufficient data whether a control technology shall have a
nominal efficiency and the level of that nominal efficiency. If, in the

emission reduction greater than the reference control technology for a
particular kind of emission point, the Administrator will publish a
Federal Register notice establishing a nominal efficiency for the
control technology.

from multiple emission points. In such cases, the percent reduction in
emissions for each emission point shall be calculated.
(v) For the purposes of the equations in paragraphs (h)(2) through
(h)(7) of this section, used to calculate credits for emission points
controlled more stringently than the reference control technology or
standard, the nominal efficiency of a pollution prevention measure is
equivalent to the percent reduction of the pollution prevention
measure. When a pollution prevention measure is used, the owner or
operator of an affected source is not required to apply to the
Administrator for a nominal efficiency and is not subject to paragraph
(i) of this section.
