General Permits and Permits by Rule for the Federal Minor New
Source Review Program in Indian Country
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) is proposing general
permits for use in Indian country pursuant to the Indian Country Minor
New Source Review (NSR) rule for new or modified minor sources in the
following five source categories: Hot mix asphalt (HMA) plants; stone
quarrying, crushing, and screening (SQCS) facilities; auto body repair
and miscellaneous surface coating operations; gasoline dispensing
facilities (GDFs); and petroleum dry cleaning facilities. In the
alternative, the EPA is also proposing permits by rule for use in
Indian country for new or modified minor sources in three of the source
categories: Auto body repair and miscellaneous surface coating
operations; GDFs; and petroleum dry cleaning facilities. The EPA is
also proposing certain changes to the Indian Country Minor NSR rule.
The proposed changes include: Extending the deadline by when true minor
sources in the oil and gas sector must receive minor source NSR
permits; and allowing general permits and permits by rule for specific
categories to create synthetic minor sources.
DATES: Comments must be received on or before March 17, 2014.
Public Hearing. If anyone contacts us requesting to speak at a
public hearing by February 4, 2014, we will hold a public hearing.
Additional information about the hearing will be published in a
subsequent Federal Register notice.

II. Purpose
A. Proposed Action
In July 2011, the EPA issued the Indian Country Minor NSR rule that
established, among other things, the requirements and process for the
preconstruction permitting of minor sources in Indian country. Under
the rule, on or after the effective date of the Indian Country NSR
rule, that is September 2, 2014, an owner or operator must obtain a
preconstruction permit from the reviewing authority \1\ if the source
will construct a new true minor source,\2\ or will modify an existing
true
[[Page 2549]]
minor source in Indian country. The rule also specified the process and
requirements for using general permits as a streamlined permitting
approach to authorize construction and modifications at true minor
sources. General permits streamline the preconstruction permitting of
new or modified true minor sources because they involve the issuance of
one permit that can apply to multiple stationary sources that have
similar emissions units.
---------------------------------------------------------------------------
\1\ In this document, reviewing authority refers to an EPA
regional office. However, tribes can become reviewing authorities if
they decide to assume responsibility for implementing the minor NSR
program in their area.
\2\ True minor source means a source that emits, or has the
potential to emit, regulated NSR pollutants in amounts that are less
than the major source thresholds under either the Prevention of
Significant Deterioration program at 40 CFR 52.21, or the Major NSR
program for Nonattainment Areas in Indian Country at 40 CFR 49.166
through 49.173, but equal to or greater than the minor NSR
thresholds in Sec. 49.153, without the need to take an enforceable
restriction to reduce its PTE to such levels. The PTE includes
fugitive emissions, to the extent that they are quantifiable, only
if the source belongs to one of the 28 source categories listed in
part 51, Appendix S, paragraph II.A.4(iii) or Sec. 52.21(b)(1)(iii)
of 40 CFR, as applicable.
---------------------------------------------------------------------------
In today's proposal, the EPA is proposing the use of two types of
minor NSR preconstruction permits to help streamline the EPA's
permitting of true minor sources that construct or modify in Indian
country and belong to one of five different source categories. The
first type of permit is a general permit. The second type is a permit
by rule, which is another mechanism for streamlining the issuance of
preconstruction permits. Permits by rule use a regulatory-type
structure to permit sources by pre-authorizing construction and
modification activities carried out in accordance with the permit's
requirements. To become covered by a permit by rule, as we are
proposing today, a source must notify the EPA that it meets the terms
of coverage and is complying with the permit's conditions but does not
need to await approval of a request for coverage.
As our preferred approach, we are proposing general permits for HMA
plants; SQCS facilities; GDFs; auto body repair and miscellaneous
surface coating operations; and petroleum dry cleaning facilities.
Specifically, we are proposing general permits for these source
categories for permitting affected emissions units and emissions-
generating activities in these source categories. As an alternative,
for GDFs, auto body repair and miscellaneous surface coating
operations, and petroleum dry cleaning facilities, the EPA is also
requesting comment on whether, in lieu of establishing general permits
for each of these categories, we should instead adopt permits by rule
for one or more of these three source categories. (In addition, as
explained in Section XI, we are requesting comment on finalizing both
permitting mechanisms for these three source categories by using
permits by rule to provide authorization to construct or modify true
minor sources and by providing general permits to establish enforceable
limitations to create synthetic minor sources.)
We are proposing the regulatory framework that the EPA will use to
establish permits by rule, and we are making available various permit
implementation documents and tools on which we request public comment.
We are proposing to extend the date by when minor sources in the oil
and gas sector must receive minor NSR permit (i.e., September 2, 2014).
Finally, we are seeking comment on a requested change in policy
provided in the Indian Country Minor NSR rule for which we have granted
reconsideration.\3\ The current policy states that general permits
cannot be used to create synthetic minor sources. We seek comment on
changing that policy to allow general permits--and permits by rule--to
create synthetic minor sources.

---------------------------------------------------------------------------
B. Areas Where the EPA Is Seeking Comment
In this action, we are seeking comment on a number of issues,
including, but not limited to:
(1) All aspects of the permit documents and implementation tools
for the following source categories (Sections VI and IX):
a. HMA plants;
b. SQCS facilities;
c. Auto body repair and miscellaneous surface coating operations;
d. GDFs; and
e. Petroleum dry cleaning facilities;
(2) The appropriateness of utilizing streamlined general permit
applications for three source categories:
a. Auto body repair and miscellaneous surface coating operations;
b. GDFs; and
c. Petroleum dry cleaning facilities;
(3) Several administrative aspects of general permits, including
(Section V):
a. Whether the EPA's proposed approach of incorporating by
reference each reviewing authority's approval of a request for coverage
into the general permit is necessary and appropriate; and
b. The appropriateness of proposed permit terms related to the
reviewing authority's ability to reopen, revise, or terminate an
individual approval of coverage under the general permit;
(4) Different aspects of the EPA's conclusion on its control
technology review that, because the control measures in this proposal
are currently used by other similar sources in other areas of the
country, the measures in the proposed permits are technically and
economically feasible, and cost-effective (Section V);
(5) Use of throughput limits as a surrogate for ton-per-year
allowable emission limitations, or, alternatively, establishment of
annual allowable emission limitations for each pollutant, and the use
of throughput limits as surrogate monitoring measures to demonstrate
compliance with ton-per-year annual allowable emission limitations
(Section V);
(6) The regulatory framework that the EPA is proposing as an
alternative to use to establish permits by rule and the streamlined
review and issuance process that the EPA is proposing whereby a source
can become covered by a permit by rule by notifying the EPA that it
qualifies for the permit, meets the terms of coverage and is complying
with the permit's conditions (but not having to wait for the reviewing
authority's approval) (Section VII);
(7) Proposal to change the policy in the Indian Country Minor NSR
rule to allow the use of both general permits and permits by rule to
create synthetic minor sources (Section X);
(8) Finalizing both permitting mechanisms for three source
categories (i.e., auto body repair and miscellaneous surface coating
operations; GDFs; and petroleum dry cleaning facilities) by providing
authorization to construct or modify true minor sources via permits by
rule and by providing enforceable limitations to create synthetic minor
sources via general permits (Section XI);
(9) Use of more than one general permit and/or permit by rule for a
source at a location (Section XI);
(10) Additional source categories for which the EPA is planning to
propose general permits and/or permits by rule (Section XII); and
(11) Proposed rule changes to the Indian Country Minor NSR rule in
five areas in three provisions (Section XIII):
a. Shortening the general permit application review process from 90
to 45 days for certain source categories;
b. Adjusting the deadline by which minor sources covered by a
general permit need to obtain a preconstruction permit;
c. Extending the permitting deadline for true minor sources within
the oil and gas source category;
d. Removing a provision to make clear that sources may seek
coverage under a general permit as soon as it is effective
[[Page 2550]]
and need not wait an additional 4 months; and
e. Adjusting the deadline for oil and gas sources for certain
registration-related requirements to be consistent with the proposed
permitting deadline extension.
III. Background
A. Tribal Air Rule
On February 12, 1998,\4\ the EPA used its authority under section
301(d) of the Clean Air Act (CAA) to find that we would not treat
tribal governments the same as states with respect to specific plan
submittal and implementation deadlines under the CAA for National
Ambient Air Quality Standards (NAAQS)-related requirements. This
finding applied to many section 110 requirements, including
requirements under section 110(a)(2)(c) to submit a program to regulate
the modification and construction of any stationary source as necessary
to assure that the NAAQS are achieved. Although we determined that
Indian tribes were not obligated to implement a permitting program, the
EPA also made clear that we continue to have a general obligation under
the CAA to ensure the protection of air quality throughout Indian
country. To that end, we also used our authority under sections 301(a)
and 301(d)(4) to establish a requirement to promulgate such federal
implementation plan (FIP) provisions as are necessary or appropriate to
protect air quality in Indian country. See 40 CFR 49.11(a). For a
number of years, the only federal CAA NSR permitting program that
applied in Indian country was the major NSR program for areas meeting
the NAAQS (``attainment'' areas) or areas for which there is
insufficient information to determine whether they meet the NAAQS
(``unclassifiable'' areas). We call this program the Prevention of
Significant Deterioration (PSD) program. No federal NSR permitting
program has covered minor sources or major sources in nonattainment
areas. Nor was there a way for major sources to take enforceable limits
and become synthetic minor sources.

http://www.gpo.gov/fdsys/pkg/FR-1998-02-12/pdf/98-3451.pdf.
---------------------------------------------------------------------------
On August 21, 2006, the EPA proposed the regulation: ``Review of
New Sources and Modifications in Indian Country'' (i.e., Indian Country
NSR rule).\5\ Within this regulation, the EPA proposed to protect air
quality in Indian country by establishing a FIP program to regulate the
modification and construction of stationary sources consistent with the
requirements of section 110(a)(2)(c) of the CAA. We call this part of
the Indian Country NSR rule the Indian Country Minor NSR rule. Under
the Indian Country Minor NSR rule, we proposed to fill a regulatory gap
and provide a mechanism for issuing preconstruction permits for the
construction of new minor sources and certain modifications of major
and minor sources in Indian country. In developing the rule, the EPA
conducted extensive outreach and consultation along with an extensive
public comment period that ended on March 20, 2007. The comments
provided detailed information specific to Indian country and the final
Minor NSR rule incorporated many of the suggestions we received. We
promulgated final rules on July 1, 2011,\6\ and the FIP became
effective on August 30, 2011.

B. Indian Country Minor NSR Rule
1. What is the Indian Country Minor NSR rule?
The Indian Country Minor NSR rule applies to new and modified minor
stationary sources and to minor modifications at existing major
stationary sources located in Indian country where there is no EPA-
approved program in place. The rule also includes a pre-construction
permits program for major sources proposing to construct in areas of
Indian country that have not attained one or more NAAQS, i.e.,
nonattainment areas. After September 2, 2014, any new stationary
sources that will emit, or will have the potential to emit (PTE), a
regulated NSR pollutant in amounts that will be: (1) Equal to or
greater than the minor NSR thresholds, established in the Minor NSR
rule; and (2) less than the amount that would qualify the source as a
major source for purposes of the PSD or nonattainment major NSR
programs, must apply for and obtain a minor NSR permit before
commencing construction of the new source.\7\ Likewise, any existing
stationary source (minor or major) must apply for and obtain a minor
NSR permit before commencing construction of a physical or operational
change that will increase the allowable emissions of the stationary
source by more than the specified threshold amounts, if the change does
not otherwise trigger the permitting requirements of the PSD or
nonattainment major NSR program(s).\8\
---------------------------------------------------------------------------
\7\ Under the current Indian Country Minor NSR rule, certain
sources may need to apply for a permit earlier than September 2014,
if the EPA finalizes a general permit for that category before that
date.
\8\ A source may, however, be subject to certain monitoring,
recordkeeping and reporting (MRR) requirements under the major NSR
programs, if the change has a reasonable possibility of resulting in
a major modification. A source may be subject to both the Indian
Country Minor NSR program and the reasonable possibility MRR
requirements of the major NSR program(s).
---------------------------------------------------------------------------
Among other things, the Indian Country Minor NSR rule created a
framework for the EPA to streamline the issuance of preconstruction
permits to true minor sources by using general permits. We explain this
framework further in the sections below.
2. What is a true minor source and how does it differ from a synthetic
minor source?
``True minor source'' means a source that emits, or has the
potential to emit, regulated NSR pollutants in amounts that are less
than the major source thresholds under either the PSD program at 40 CFR
52.21, or the Major NSR program for Nonattainment Areas in Indian
Country at 40 CFR 49.166 through 49.173, but equal to or greater than
the minor NSR thresholds in Sec. 49.153, without the need to take an
enforceable restriction to reduce its PTE to such levels. The PTE
includes fugitive emissions, to the extent that they are quantifiable,
only if the source belongs to one of the 28 source categories listed in
part 51, Appendix S, paragraph II.A.4(iii) or Sec. 52.21(b)(1)(iii) of
40 CFR, as applicable. For example, a hot mix facility, located in a
sulfur dioxide (SO2) attainment area, that has a maximum
potential to emit of 135 tons per year (tpy) of SO2, without
the need to take an enforceable restriction to reduce its PTE to such
levels, would qualify as a true minor source.
By contrast, ``synthetic minor source'' means a source that
otherwise has the potential to emit regulated NSR pollutants in amounts
that are at or above those for major sources, but that has taken a
restriction so that its PTE is less than such amounts. Such
restrictions must be enforceable as a legal and practical matter. For
example, a hot mix facility, located in an SO2 attainment
area, that has an unrestricted potential to emit 270 tpy, but that is
legally constrained to emit only 135 tpy of SO2 because the
source has taken a throughput limit made enforceable
[[Page 2551]]
through a permit (i.e., a limit on how much hot mix product it can
produce), would qualify as a synthetic minor source. In the preamble to
both the proposed and final Indian Country Minor NSR rule, the EPA
indicated that it would not use general permits to allow otherwise
major sources to create synthetic minor sources.\9\ We discuss this
issue more fully in Section X and request comment on our proposal to
change this policy and also allowing permits by rule to create
synthetic minor sources.
---------------------------------------------------------------------------
\9\ Note that the current regulatory language does not restrict
the use of general permits in this manner.
---------------------------------------------------------------------------
3. What are the minor NSR thresholds?
The ``minor NSR thresholds'' establish cutoff levels for each
regulated NSR pollutant. If a source naturally has a potential to emit
in amounts lower than the thresholds, then it is exempt from the Indian
Country Minor NSR rule (see Table 2 and 40 CFR 49.153) for that
pollutant. New or modified sources which naturally have a potential to
emit in amounts that are: (1) Equal to or greater than the minor NSR
thresholds; and (2) less than the major NSR thresholds (generally 100
to 250 tpy) are ``minor sources'' of emissions and subject to the
Indian Country Minor NSR rule requirements at 40 CFR 49.151 through
161.

------------------------------------------------------------------------
4. What is a general permit?
The Indian Country Minor NSR rule specified the process and
requirements for using general permits to authorize construction and
modifications at true minor sources as a streamlined permitting
approach. A general permit, for purposes of this action, is a permit
document that contains standardized requirements that multiple
stationary sources can use. The EPA may issue a general permit for
categories of emissions units or stationary sources that are similar in
nature, have substantially similar emissions, and would be subject to
the same or substantially similar permit requirements.\12\ ``Similar in
nature'' refers to size, processes, and operating conditions. The
purpose of a general permit is to provide for protection of air quality
while simplifying the permit process for similar minor sources. General
permits offer a cost-effective means of issuing permits and provide a
quicker and simpler mechanism for permitting minor sources than the
site-specific permitting process.
---------------------------------------------------------------------------
\10\ If part of a tribe's area of Indian Country is designated
as attainment and another part as nonattainment, the applicable
threshold for a proposed source or modification is determined based
on the designation where the source would be located. If the source
straddles the two areas, the more stringent thresholds apply.
\11\ In extreme ozone nonattainment areas, section 182(e)(2) of
the CAA requires any change at a major source that results in any
increase in emissions to be subject to major NSR permitting. In
other words, any changes to existing major sources in extreme ozone
nonattainment areas are subject to a ``0'' tpy threshold, but that
threshold does not apply to minor sources.

Country,'' U.S. Environmental Protection Agency, 76 FR 38770, July
1, 2011, https://www.federalregister.gov/articles/2011/07/01/2011-14981/review-of-new-sources-and-modifications-in-indian-country.
---------------------------------------------------------------------------
While the final Indian Country Minor NSR rule contemplated issuance
of general permits by the EPA regions, we have determined (for the
permits on which we are taking comment here) that a nationwide action
is appropriate. Through this action, we are proposing to issue general
permits to serve as preconstruction permit authorizations that contains
emission limitations and other restrictions to govern how a sources may
construct, modify and operate. National general permits streamline the
permit issuance process by establishing universal requirements through
one notice for specific types of emissions activities at multiple
sources across the country. The EPA believes that the general permit
approach is appropriate for the source categories in today's proposal
where the control equipment or techniques are generally similar from
region to region.
It also allows a reviewing authority to notify the public through
one notice that it intends to apply these requirements to any eligible
source that seeks coverage under the permit in the future. This
minimizes the burden on reviewing authorities' resources by eliminating
the need to issue separate permits for each individual minor source
within the source type or category covered by the general permit. Use
of a general permit also decreases the time required for an individual
minor source to obtain a preconstruction permit because the application
process is standardized.
The Indian Country Minor NSR rule describes the process the EPA
will use to issue general permits for the minor NSR program. A general
permit must be issued in accordance with the requirements in Sec.
49.156. Briefly, these requirements address public availability of
information, public notification and participation, and public
comments. In addition, as discussed in Section IX, we are providing
implementation tools to
[[Page 2552]]
guide sources through a series of questions to determine whether they
meet the criteria to be eligible for coverage under a general permit.
C. What is a permit by rule?
Like a general permit, a permit by rule is a standard set of
requirements that can apply to multiple stationary sources with similar
emissions characteristics. For purposes of this action, a permit by
rule would differ from a general permit in that the agency would codify
a permit by rule directly into the Indian Country Minor NSR rule. The
process for a source to apply for coverage under a permit by rule, and
the process for the reviewing authority to grant coverage under a
permit by rule, are more streamlined compared to a standard general
permit, or a site-specific permit. Section VII provides a description
of the source application for permits by rule.
IV. Description of General Permit Program in Indian Country and the
EPA's Use of This Package To Satisfy the General Permit Issuance
Process
A. General Permit Program
The EPA codified the framework it would follow to issue general
permits for minor sources in the Indian Country Minor NSR rule in 40
CFR 49.156. While it was not necessary for the EPA to codify this
framework to issue general permits, the EPA nonetheless created the
regulatory framework to better inform the public of the process the EPA
will use to issue general permits. Per the framework, to issue a
general permit, the reviewing authority must follow the requirements
for public participation contained in Sec. 49.157. These provisions
require the reviewing authority then to provide a notice that a draft
permit is available for comment. The regulations list a number of ways
in which a reviewing authority can provide notice to the public, and
also allow the reviewing authority to use other means of notification
as appropriate. See 40 CFR 49.157(b)(1)(ii)(E). We have opted to
provide notice to the public regarding the present proposal of general
permits for five source categories through use of the Federal Register.
We believe this means is appropriate in this case because we intend to
apply these general permits in all areas of Indian country subject to
the Indian Country Minor NSR program and the Federal Register provides
a nationwide circulation of the notice. We will also mail a copy of
each permit to the appropriate Indian governing bodies and the tribal,
state and local air pollution agencies in adjacent air jurisdictions
that may be impacted by the air pollution sources that use the general
permit in accordance with 40 CFR 49.157(b)(1)(i).
The existing regulations also identify the type of information that
a reviewing authority must make available to the public, and list a
number of elements to be included in the public notice. See 40 CFR
49.157(a) and (b)(2). We are satisfying these requirements in this
proposal in a wide-ranging manner by providing the public access to the
application forms we will require an applicant to complete, and the
other implementation tools for each general permit. (We discuss these
tools in greater detail in Section IX of this preamble.) Many of these
requirements relate to information that is best made available when an
individual applicant applies for coverage under a specific general
permit. We will make information specific to an individual source's
request for coverage under a general permit available at the time we
provide notice of the source's request for coverage.
After providing adequate public notice of the availability of the
draft permit, the reviewing authority must allow a period of at least
30 days for the public to comment on the permit, and to request a
public hearing. See 40 CFR 49.157. We are satisfying these requirements
by using this package to propose and take comments on the general
permits. Once we finalize a general permit, it will be used by the
EPA's regional office reviewing authorities \13\ for sources requesting
coverage under the permit.
---------------------------------------------------------------------------
\13\ The Administrator delegated the authority to each EPA
Regional Administrator to carry out all aspects of the Indian
Country minor NSR program, including issuing general permits and
approving individual coverage under a general permit.
---------------------------------------------------------------------------
The regulations set forth the provisions for a final permit to
undergo administrative and judicial review in accordance with Sec.
49.159. The procedures governing appeals of NSR permits to the
Environmental Appeals Board will govern administrative review of these
general permits. Issuance of a general permit is a final agency action
with respect to all aspects of the general permit except its
applicability to an individual source. The provisions of 40 CFR 49.159
will continue to govern administrative and judicial review of the EPA's
approval of an individual source's request for coverage. After the
reviewing authority approves a request for coverage by an individual
source, a party may appeal only the applicability of the general permit
to that particular source.
Although we are using a Federal Register notice to initially
establish the general permits, we intend to use other methods also
consistent with procedures in 40 CFR 49.159 to reopen or
administratively amend the final permits if we determine it is
necessary and appropriate. A reviewing authority may reopen and revise
a final general permit for cause after providing the opportunity for
notice and comment under Sec. 49.157. Revisions to a final general
permit may be appropriate, for example, when the reviewing authority
decides to issue a new general permit for the same category to account
for advances in control technology or for other pertinent reasons.
However, when a reviewing authority issues a new general permit,
sources operating under the existing general permit will be able to
continue to operate under the existing permit unless and until the
source subsequently proposes to modify.\14\
---------------------------------------------------------------------------
\14\ If EPA revises an existing general permit, then the
original permit can no longer be used for new and modified minor
sources. The new general permit will be used for new and modified
minor sources in the relevant source category. The existing general
permit remains in place for existing facilities unless and until
they choose to modify.
---------------------------------------------------------------------------
B. How do sources apply for general permits?
40 CFR 49.156(e) describes the procedure for sources to obtain
coverage under a general permit. At the time a source submits a request
for coverage under a general permit, it must submit a copy of such
request to the appropriate Indian governing body for the area of Indian
country where the source is locating. The reviewing authority must act
on the source's request for coverage under the general permit as
expeditiously as possible, but it must notify the source of the final
decision within 90 days of its receipt of your coverage request. The
source's reviewing authority must comply with a 45-day completeness
review period to determine if the request for coverage under a general
permit is complete. Therefore, within 30 days after the receipt of the
source's coverage request, the reviewing authority must make an initial
request for any additional information necessary to process your
coverage request and the source must submit such information within 15
days. If the source does not submit the requested information within 15
days from the request for additional information and this results in a
delay that is beyond the 45-day completeness review period, the 90-day
permit issuance period for the general permit will be extended by the
additional days the source takes to submit the requested information
beyond the 45-day period. If the reviewing authority fails to notify
[[Page 2553]]
you within a 30-day period of any additional information necessary to
process the source's coverage request, it will still have 15 days to
submit such information and the reviewing authority must still grant or
deny the request for coverage under a general permit within the 90-day
general permit issuance period and without any time extension.
If the reviewing authority determines that the source's request for
coverage under a general permit has all the relevant information and is
complete, it will notify the source in writing as soon as that
determination is made. If the source does not receive from the
reviewing authority a request for additional information or a notice
that the request for coverage under a general permit is complete within
the 45-day completeness review period, the request will be deemed
complete.
After permit coverage is granted, under 40 CFR 49.156 (e), coverage
under a general permit becomes invalid if a source does not commence
construction within 18 months after the effective date of coverage
under a general permit, if the source discontinues construction for a
period of 18 months or more, or if the source does not complete
construction within a reasonable time. The reviewing authority may
extend the 18-month period upon a satisfactory showing that an
extension is justified, and the 18-month limit does not apply to the
time period between construction of the approved phases of a phased
construction project. In those cases, construction of each such phase
must commence within 18 months of the projected and approved
commencement date.
In Section XIII, the EPA proposes to amend 40 CFR 49.156(e) to
shorten the permit application procedure to 45 from 90 days.
In Section IX, we describe the implementation documents and tools
that we are making available for comment to assist sources with
applying for general permits.
C. What are the required permitting elements?
For general permits, these elements are discussed in the Indian
Country Minor NSR rule and promulgated at 40 CFR 49.155(a) and include:
The effective date of the permit and the date by which a
source must commence construction in order for the permit's coverage to
remain valid (i.e., 18 months after the permit effective date);
The emissions units subject to the permit and their
associated emission limitations (and other permit conditions);
Monitoring, recordkeeping, reporting and testing
requirements to assure compliance with the emission limitations; and
A severability clause to ensure the continued validity of
the other portions of the permit in the event of a challenge to a
portion of the permit.
V. Source Categories for Which Draft General Permits in Indian Country
Are Available for Public Review
A. Notice of Proposed General Permits
In accordance with 40 CFR 49.171(b)(1)(1)(E), we are providing the
public with a copy of five draft general permits covering (1) HMA
plants; (2) SQCS facilities; (3) auto body repair and miscellaneous
surface coating operations; (4) GDF facilities; and (5) petroleum dry
cleaning facilities. Copies of each of these permits and the following
four associated permitting documents are available in the docket for
this notice (EPA-HQ-OAR-2011-0151) and at http://www.epa.gov/air/tribal/tribalnsr.html:
(1) Request for Coverage (Application);
(2) Questionnaire;
(3) Instructions; and
(4) PTE calculator.
The applications for three of the five source categories in today's
proposal (i.e., auto body repair and miscellaneous surface coating
operations; GDFs; and petroleum dry cleaning facilities) are
streamlined and ask for contact and location information and general
source-specific information (more detailed source-specific information
would be required from sources seeking coverage under the HMA and SQCS
general permits). This is discussed further in Section IX.
The general permits will authorize construction of, or any change
to, any of the affected emission units, or pollutant emitting
activities named in the permit, at any proposed true minor source that
meets the applicability and eligibility statements in the permit, and
for which the reviewing authority approves coverage under the permit.
We request comment on all aspects of the general permits and the
associated forms and documentation provided to assist the stationary
sources specified in the permits in complying with the Indian country
minor NSR preconstruction permitting and post-construction operating
requirements. In Section VIII, we propose, in the alternative, permits
by rule for auto body repair and miscellaneous surface coating
operations, GDFs and petroleum dry cleaning facilities. Should we
decide to finalize a permit by rule for any of these categories, then
we may not finalize the draft general permit for that category.
Alternatively, we may opt to finalize both permitting mechanisms for
the same source category, and may tailor one of the permitting
mechanisms to provide authorization to construct or modify true minor
sources (i.e., permits by rule) and another to provide enforceable
limitations to create synthetic minor sources (i.e., general permits).
(See Section X, for further discussion of the use of general permits
and permits by rule to create synthetic minor sources.) We specifically
request comment on this ``hybrid'' approach (see Section XI, for
further discussion on the hybrid approach).
For the five source categories in today's action, we are proposing
general permits as our preferred approach. We have crafted our proposal
to ensure air quality is protected and to provide a streamlined
approach where appropriate. Specifically, for HMA plants and SQCS
facilities, the EPA is proposing (1) that we retain the 90-day
application review process provided in the Indian Country NSR Rule; and
(2) that we provide lengthier, more detailed applications. Lengthier,
more detailed applications are appropriate for source operations such
as HMA and SQCS facilities that involve multiple pollutants where the
reviewing authority needs to conduct a review to evaluate whether an
individual source meets the requirements in the permit. However, we
also recognize that a more streamlined approach may be appropriate for
other source categories with few pollutants of concern and in which the
operations are less complex. For those source categories (i.e., auto
body repair and miscellaneous surface coating operations; GDFs; and
petroleum dry cleaning facilities), the EPA is proposing to change the
underlying rule to provide a shorter application review period (see
Section XIII) and a shorter application (see Section IX). The permits
by rule proposed as an alternative for these same three categories
would take that streamlining a step further (see Section VII).
The remainder of this section outlines the general structure of
each of the draft general permits, and requests comment on issues that
are common among the draft general permits. Specifically, we are
requesting comment on:
(1) Whether the EPA should allow the use of each general permit to
create synthetic minor sources;
(2) Whether the EPA's proposed approach of incorporating by
reference each reviewing authority's approval of a request for coverage
into the general
[[Page 2554]]
permit is necessary and appropriate; and
(3) The appropriateness of proposed permit terms related to the
reviewing authority's ability to reopen, revise, or terminate an
individual approval of coverage under the general permit.
This section also describes the general process we undertook for each
of the control technology reviews required to establish the terms and
conditions of each draft general permit, and requests comment on our
conclusions on several aspects of the control technology reviews.
Additional information and supporting analyses on each of these
draft permits are located in the background documents. These documents
are available at Docket ID No. EPA-HQ-OAR-2011-0151 and online at
http://www.epa.gov/air/tribal/tribalnsr.html.
B. Structure of General Permits
Each draft general permit contains a similar overall structure. The
cover page of each draft permit contains general information on the
draft permit. First, it briefly describes the applicability of the
permit to a particular source category or emissions activity the
general permit regulates in accordance with 40 CFR 49.156(d)(1). This
description varies for each of the draft permits, depending on the
emissions activity covered by the draft permit.
Second, the cover page limits eligibility for coverage under the
permit to true minor sources. We included this limitation to allow
permitting authorities the ability to process a permit application for
inherently larger sources using the more extended time periods the
Indian Country Minor NSR rule provides for case by case, site specific
review. We also include this limitation in the draft permits to remain
consistent with our current policy that we will not allow sources to
use general permits to create synthetic minor sources.
We recognize, however, that limiting eligibility of these draft
permits to only true minor sources could limit the number and types of
sources that could take advantage of the streamlined, general
permitting process. We also recognize that there is similar emissions
potential between true minor sources and properly regulated synthetic
minor sources as we discuss in Section X. We request comment on whether
there are reasons that the final general permits should retain the true
minor limitation on eligibility for one or more of the permits, or
whether we should expand the eligibility of these draft general permits
to ``synthetic minor'' sources. After reviewing comments received, we
may amend one or more of the final permits to allow any minor source to
apply for coverage under that permit.
Third, following the eligibility statement, the draft permit
directs applicants to the specific information that an applicant must
include in a request for coverage under the permit in accordance with
40 CFR 49.156(d)(2)(ii) and (iii). The request for coverage serves as
the permit application and the information in the application will
differ for each draft permit. We discuss the application and
implementation tools to assist true minor sources in determining
whether a source is eligible for coverage under a general permit in
Section IX.
Fourth, the draft permit contains a statement that incorporates
each reviewing authority's approval of a request for coverage into the
general permit. Sections 1 through 6 of the general permit, and the
most current approval of the request for coverage, must be posted
prominently at the facility, and each affected emissions unit and any
associated air pollution control technology must be labeled with the
identification number listed in the Approval of the Request for
Coverage for that permitted source. We request comment on the inclusion
of this condition in the permits given that the Indian Country Minor
NSR rule only requires posting of the approval of coverage.
As we developed the draft permits, we envisioned situations in
which the reviewing authority may need to revise information contained
in the approval notice some time after issuance. For example, a source
covered by a general permit may subsequently change ownership. A
reviewing authority may delegate responsibilities for the general
permit to a tribal air pollution control agency. A source may
subsequently need to revise something in its request for coverage that
would alter elements of the approval. For example, a source may
misidentify an equipment identification number in its request for
coverage, or decide to expand or limit the scope of the modification. A
reviewing authority may need to alter its approval of the request for
coverage for these situations. The general permit provisions at 40 CFR
51.156(b)(2) broadly reference 40 CFR 49.159, which specifically
addresses the reviewing authority's ability to reopen or
administratively amend permits. The provisions, however, do not
specifically delineate how they apply to an approval of a request for
coverage under a general permit. By incorporating the approval into the
general permit, we ensure that the revision procedures contained in 40
CFR 49.159 apply to revisions a reviewing authority may make to the
approval of the request for coverage. We request comment on this
approach for incorporating the approval of the request for coverage
into the general permit. Alternatively, we request comment on whether
such incorporation is unnecessary and on whether to apply the
procedures in 40 CFR 49.159 to the approval of the request for
coverage, or whether the EPA should amend the existing regulations at
Sec. 51.156 to address amendments to the request for coverage.
Fifth, the draft permit contains information on the reviewing
authority's right to terminate or revise the general permit. The
general permit provisions in the Indian Country Minor NSR rule provide
the reviewing authority the ability to revise, revoke and reissue, or
terminate a general permit. In harmony with those provisions, the draft
permits include authority for a reviewing authority to revise or
terminate an approval of a request for coverage. We are adding these
provisions to the general permit, under the authority of 40 CFR
49.165(d), to clarify how the Indian Country Minor NSR rule intended
these provisions to apply to an individual request for coverage. We
request comment on inclusion of these provisions in the general permit,
or, alternatively, whether the EPA should amend the Indian Country
Minor NSR rule to expressly delineate the reviewing authority's right
to revise or terminate an individual source's coverage under a general
permit.
Finally, the draft permit contains a statement indicating that the
definitions contained in the Indian country rule govern use of those
terms within the general permit. The statement also refers permittees
to a section of the permit that contains definitions that may be
specific to the source categories or emissions activities covered by
the general permit; and indicates that when a term is not otherwise
defined we will interpret that term consistent with normal business
use. We, nonetheless, request comment on whether we should include any
additional definitions to improve the clarity of the general permits.
Following the general information section, each draft permit
contains the enforceable terms and conditions of the general permit.
Section 1 of the Terms and Conditions provisions contains general
provisions that, with only a few exceptions, are similar for all the
general permits. These provisions contain statements that the rules
require in each permit pursuant to 40 CFR 49.155.
[[Page 2555]]
In each permit, the general provisions are followed by emission
limitations and other operational restrictions or specifications, and
monitoring, recordkeeping, and reporting requirements that are unique
to each of the permits. The notice and reporting requirements are
followed by a section outlining the reviewing authority's ability to
change the general permit, including the approval of the request for
coverage, a section on requesting coverage under the permit, and
attachments with abbreviations and acronyms, a list of definitions
referenced on the cover page of the permit and a list of reviewing
authorities and areas of coverage. Attachments to the HMA plant and
rock crushing permits also contain requirements to minimize fugitive
dust emissions. An attachment to the GDF permit contains requirements
for vapor balance system design criteria, management practices, and
performance testing. Attachments to the auto body repair and
miscellaneous surface coating operations general permit provide
standards for cold cleaner degreasers and training and certification
requirements for spray-applied surface coating personnel. An attachment
to the petroleum dry cleaning facilities permit contains requirements
specific to serious, severe, or extreme ozone nonattainment areas.
C. The EPA's Control Technology Review
With the exception of the GDF general permit, each permit
establishes specific numerical limitations on the quantity, rate or
concentration of emissions for each regulated NSR pollutant emitted by
each affected emissions unit. (The GDF permit includes equipment
requirements.) For each general permit, in a manner similar to what a
permitting authority would be expected to do for an individual source,
we established these control technology-based requirements by
researching both state and local air quality programs to identify
control technologies or other emissions reduction measures used by
similar sources in surrounding areas, and by reviewing requirements
contained in existing 40 CFR parts 60, 61 and 63 emissions standards
that apply to these source categories. The draft permits build upon the
requirements in the part 60, 61, and 63 emissions standards by
including some control technology measures found in state and local
agencies' general permits for these source categories.
The background documents for each draft permit explain the state
and local programs we reviewed to identify control technology options
in each source category. We believe that, because these control
measures are currently used by other similar sources in other areas of
the country, that they are technically and economically feasible, and
cost effective. We request comment on this conclusion, and invite
commenters to submit specific information that would indicate that
either: (1) The measures in the draft permits are not economically
feasible and/or cost-effective; or (2) additional economically feasible
and cost-effective measures are available and appropriate to include in
the final general permits.
In determining specific emission limitations and control measures
for each permit, we considered the general, local air quality
conditions in Indian country. Notably, Indian country contains both
attainment and nonattainment areas for different regulated NSR
pollutants.\15\ In some cases, for areas designated as nonattainment
for a given pollutant, the draft permits contain more stringent
emission limitations for that pollutant (or precursors of that
pollutant). These control requirements will help mitigate any further
degradation of air quality in those areas. In other cases, however, the
draft permits do not include different emission limitations based on
the attainment status of the area. In these situations, we determined
that the emission limitations are sufficient to protect air quality in
both attainment and nonattainment areas.

nonattainment areas in Indian Country are available online at http://www.epa.gov/air/tribal/tribalnsr.html and Docket ID No. EPA-HQ-OAR-
2011-0151. NAAQS for which the EPA has designated nonattainment
areas are: ozone (2008 NAAQS), PM10 (1987 NAAQS),
PM2.5 24-Hour (2006 NAAQS), and PM2.5 Annual
(1997 NAAQS). There are no tribal lands in nonattainment for
SO2 (2010 NAAQS), NO2, lead (2008 NAAQS), and
CO.
---------------------------------------------------------------------------
For HMA plants and SQCS facilities, we also added additional
provisions related to the location of the emitting activities and the
source property boundary. We call these provisions, which are designed
to minimize the impacts of emissions, setback requirements. Under the
setback requirement, sources may not locate within a specific distance
from the property boundary and nearest residences. In reviewing state
and local air agency general permits, we found that permitting
authorities in Alaska and Washington include setback provisions to
protect local ambient air quality from potential source impacts. We
find that these provisions are both reasonable and prudent measures to
protect local air quality, and are economically feasible and cost
effective. We, therefore, included similar measures in the draft
permits. We discuss the specific setback requirements for each category
in Section VI.
We welcome comments identifying other source categories for which a
setback requirement should apply. We also welcome comments on the types
of buildings from which we should establish setbacks (e.g., schools,
nursing homes). We further request comment on whether the setback
requirement conflicts with tribal authority over zoning-related
matters, and, if so, on how we should resolve that conflict.
To further protect against adverse local air quality impacts, the
draft permits assure that no source will cause or contribute to NAAQS
or PSD increment violations by prohibiting emissions that would result
in such impacts. Thus, reviewing authorities will consider any air
quality concerns unique to specific areas that arise after issuance of
the general permits in this proposal when determining whether an
individual permit applicant is eligible for coverage under the general
permit. For example, if a source wants to locate in an area with air
quality levels approaching or violating the NAAQS, the reviewing
authority may need to request that a source apply for a site-specific
permit so that the potential for greater control than that afforded by
the general permit can be evaluated.
In conducting the control technology review, we also considered the
anticipated growth rate of the source categories. In general, we do not
anticipate significant increases in the growth rates for these five
source categories for the foreseeable future, as we identified no
information indicating that that is the case.\16\ Thus, we do not
believe that emissions increases from these categories will pose unique
or unprecedented impacts on air quality in the near future that might
warrant a more stringent approach to controlling emissions than
contained in the draft permits. We request comment on our conclusion
about anticipated economic growth in these source categories and
regions, and the reasonableness of the emission limitations and control
measures specified in the draft permits.

---------------------------------------------------------------------------
[[Page 2556]]
D. Scope of Coverage Under Each General Permit
In the Indian Country Minor NSR rule, the EPA stated that it may
use the general permit mechanism to issue permits to ``similar'' types
of emissions units or minor sources. This limitation on the ability to
issue general permits is consistent with the EPA's longstanding
interpretation of the CAA as it relates to the ability of a permitting
agency and source to use standardized protocols to meet CAA permitting
requirements. The general permits we are proposing meet the limitation
that general permits apply only to similar sources, because each of the
permits covers only affected emission units or emissions generating
activities that are: (1) specifically identified by name in the permit;
(2) generate the same regulated NSR pollutants in the same manner and
magnitude; and (3) are associated only with operations within a defined
source category.\17\ We discuss the specific scope of each draft
general permit in more detail in Section VI below and in the background
document for each draft general permit.
---------------------------------------------------------------------------
\17\ These criteria are not the sole manner for demonstrating
that a general permit applies only to similar sources, but they
serve as examples of the types of characteristics that may be
relevant.
---------------------------------------------------------------------------
E. Surrogate Annual Allowable Emission Limitations
The Indian Country Minor NSR rule requires the reviewing authority
to establish annual allowable emission limitations for each affected
emissions unit and for each NSR regulated pollutant emitted by the
unit, if the unit is issued an enforceable limitation lower than the
PTE of that unit. See 40 CFR 49.155(a)(2). For the five source
categories in this proposal, some states (but not all) provide both
annual ton per year allowable emission limitations and throughput
limits in their general permits. Other state reviewing authorities
provide only overall production limits that limit the amount of
throughput a facility can process over a period of time. We believe
that production limits serve as a reasonable surrogate for ton per year
emission limitations, when there is a direct correlation between the
amount of material processed and the amount of pollution emitted. We
also believe that monitoring throughput rather than actual emissions
may provide a more cost-effective method of demonstrating compliance.
For example, HMA facilities regularly track a facility's throughput,
but do not necessary analyze specific emissions discharges. Thus,
reliance on throughput limits provides a more cost-effective approach
to regulate emissions and we believe will enhance the potential for
compliance with the draft permit for this and other categories. In
Section VI, we request comment on our use of throughput limits as a
surrogate for annual ton per year allowable emission limitations.
Alternatively, we request comment on whether we should establish annual
allowable emission limitations for each pollutant, and use throughput
as a surrogate monitoring measure to demonstrate compliance with a ton
per year annual allowable emission limitation.
In a related matter, in Section X of this preamble, we indicate
that we have granted reconsideration on the issue of allowing reviewing
authorities to use general permits to create synthetic minor sources
and propose to change the current policy. If the EPA allows otherwise
major sources to qualify as synthetic minor sources through use of
general permits, we request comment on specific changes that we would
need to include in the production limits of each permit to properly
regulate synthetic minor sources for these categories. For example,
should the EPA establish higher annual tpy allowable emission
limitations or surrogate production limits that are just below the
major source thresholds for each regulated NSR pollutant, or should the
EPA maintain the limitations in the current draft permits to maintain
an adequate compliance margin?
F. Requirements of the Endangered Species Act (ESA) and the National
Historic Preservation Act (NHPA) \18\
---------------------------------------------------------------------------
\18\ These requirements apply to both general permits and
permits by rule. Only general permits are mentioned here but the
requirements apply identically to both permit types. Section VII.C.
is specific to permits by rule and notes that these requirements
also apply to permits by rule.
---------------------------------------------------------------------------
The ESA requires federal agencies to ensure, in consultation with
the U.S. Fish and Wildlife Service and/or the National Marine Fisheries
Service (the Services), that any action they authorize, fund, or carry
out will not likely jeopardize the continued existence of any listed
threatened or endangered species, or destroy or adversely modify the
designated critical habitat of such species. Under relevant ESA
implementing regulations, federal agencies consult with the Service(s)
on actions that may affect listed species or designated critical
habitat. The NHPA requires federal agencies to take into account the
effects of their undertakings on historic properties--i.e., properties
that are either listed on, or eligible for listing on, the National
Register of Historic Places--and to provide the Advisory Council on
Historic Preservation (the Council) a reasonable opportunity to comment
on such undertakings. Under relevant NHPA implementing regulations,
NHPA consultations are generally conducted with the appropriate Tribal
and/or State Historic Preservation Officers in the first instance, with
opportunities for direct Council involvement in appropriate
circumstances, including, for example, consultations in connection with
undertakings affecting multiple tribes or states. The Indian Country
Minor NSR program has increased the number of activities for which the
EPA is the permitting authority. To meet ESA and NHPA requirements, we
have developed a process for compliance with these laws when issuing
the general permits. The EPA intends to consult with the Services and
the Council on our general permits and the proposed procedures to
address potential effects on relevant protected resources.
For purposes of general permits, the EPA intends to adopt a
framework that provides appropriate protection for listed species and
critical habitat and historic properties. The EPA believes, based on
the evaluation of available information, that the sources that are the
subject of this proposal are unlikely to present a significant risk to
listed species and critical habitat and to historic properties because
they are by their nature small, low emitting sources. However, to
ensure listed species and critical habitats and historic properties are
protected, the EPA has developed a framework in the general permits
that requires the source to identify and assess effects before a
request for coverage under the general permit is submitted to the EPA.
Requiring this assessment should help identify any concerns related to
potential impacts on listed species/critical habitat or historic
properties early in the process when the greatest opportunities to
mitigate or avoid any impacts--including changes to the facility's
location or footprint--are available. This framework is similar to
procedures established by the Office of Water for the National
Pollutant Discharge Elimination System General Permit for Stormwater
Discharges from Construction Activities.\19\ The EPA believes that
requiring a similar process in both the general permits, and the
general stormwater permits, will
[[Page 2557]]
streamline the process for all concerned: The applicants, the EPA, the
tribes, and the Services.

(NPDES) General Permit for Stormwater Discharges from Construction
Activities,'' U.S. Environmental Protection Agency, 77 FR 12286,

---------------------------------------------------------------------------
The screening processes developed in the permits for both the ESA
and NHPA require the applicant to develop information about the
possible effects of the proposed new or modified facility, which
includes appropriate outreach to relevant expert resource agencies.
Such information and a certification regarding the outcome of the
applicant's screening procedures are submitted to the EPA as part of
the request for coverage under the general permit. This information is
included as an appendix to the applications for requests for coverage
for each of the general permits. The EPA will review this information
as part of determining whether a source is eligible for coverage under
the general permit. Because we have limited the applicability of the
general permits to categories of sources that have low emissions, we do
not expect they are likely to adversely affect listed species/critical
habitat, nor should they have potential effects on historic properties.
However, if, through the procedures required in the permit, a source is
determined to have an adverse effect on listed species/critical habitat
or potential effects on a historic property, the EPA retains the
authority to deny coverage under the general permit, or permit by rule,
and to proceed with source-specific permitting and consultation with
the appropriate resource agency(ies).
VI. Summary of Specific Terms and Conditions of the General Permits and
Request for Comment
In the following sections, we provide a brief summary of the source
category regulated by each general permit and areas of each draft
general permit on which we specifically seek public comment. Because
the areas upon which we specifically seek comment in the HMA plant and
SQCS facility general permits are common among the two permits, we have
combined the request for comment section on these permits into one
subsection. In this preamble, we are not delineating every aspect of
the requirements of the general permits. Instead, we refer readers to
the draft permits and associated background information to review all
the detailed requirements we include in each general permit. Although
we are soliciting comments on specific aspects of the draft permits,
we, nonetheless, invite the public to comment on all relevant aspects
of the draft permits.
A. HMA Plants
1. What is an HMA plant?
An HMA plant manufactures hot mix asphalt by heating and drying
aggregate material and then mixing it with asphalt cements. An HMA
plant consists of an assembly of mechanical and electronic equipment
used to prepare hot aggregate and mineral filler for mixing to make hot
mix asphalt. The facility includes any combination of the following
activities/equipment: Dryers, liquid asphalt storage tanks, fuel oil
storage tanks, auxiliary heaters (including hot oil heaters), material
storage handling and transfer systems, generators, storage bins/silos,
storage piles, and haul roads. An HMA plant can be constructed as a
permanent plant, a skid-mounted (easily relocated) plant, or a portable
plant.
HMA paving materials are a mixture of size-graded, high quality
aggregate, which can include reclaimed asphalt pavement (RAP), and
liquid asphalt cement. The production process involves sorting and
drying the aggregate, heating the asphalt binder, and heating and
applying the mixture. Aggregate material can be produced from numerous
sources, including natural rock, RAP, reclaimed concrete pavement
(RCP), glass, fly ash, bottom ash, steel slag, recycled asphalt
shingles, and crumb rubber. Aggregate and RAP (if used) constitute over
92 percent by weight of the total mixture. Aside from the amount and
grade of asphalt cement used, mix characteristics are determined by the
relative amounts and types of aggregate and RAP used. A certain
percentage of fine aggregate (less than 74 micrometers in physical
diameter) is required for the production of good quality HMA.\20\

Factors, Volume 1: Stationary Point and Area Sources; Chapter 11.1--
Hot Mix Asphalt Plants; U.S. Environmental Protection Agency; http://www.epa.gov/ttn/chief/ap42/index.html.
---------------------------------------------------------------------------
There are four types of HMA plants based on the type of
manufacturing process used: (1) Batch mix plants; (2) continuous mix
(mix outside dryer drum) plants; (3) parallel flow drum mix plants; and
(4) counterflow drum mix plants. Historically, about 85 percent of
manufacturing plants have been of the counterflow drum mix design,
while batch plants and parallel flow drum mix plants account for 10
percent and 5 percent, respectively.\21\
---------------------------------------------------------------------------
\21\ Ibid.
---------------------------------------------------------------------------
The emissions associated with HMA plants are generated by: (1) Raw
materials acquisition and manufacturing processes; and (2)
transportation of raw materials during manufacture and transportation
to the roadway construction site. The emissions from HMA plants consist
of: (1) Combustion emissions from mixer/dryers, auxiliary heaters, and
generators; (2) PM emissions from the mixing/drying process and the
material handling process; and (3) fugitive PM emissions from haul
roads. The CO emissions from the batch mix plants are significantly
higher than the CO emissions from drum mix plants due to the incomplete
combustion process occurring in the batch mixer/dryers.
2. What is in the proposed HMA general permit?
This proposed general permit would apply to the construction of new
true minor source HMA plants or the modification of existing true minor
HMA plants, located in Indian country. This general permit does not
apply to HMA plants that perform contaminated soil remediation, and
does not apply to cold mix asphalt production facilities. The draft
permit contains emission limitations requirements for the following
affected emission units:
Dryers;
Systems for screening, handling, storing, and weighing hot
aggregate;
Systems for mixing hot mix asphalt;
Loading transfer, and storage systems associated with
emission control equipment;
Fuel storage tanks; and
Stationary engines.
The permit requires dryers/mixers to be controlled by a baghouse,
fugitive emissions controlled by a fugitive dust control plan, and
engines to be controlled to appropriate standards. Fuel used in the
dryer/mixer and auxiliary heaters must be limited to natural gas,
distillate fuel, and biodiesel. The stationary engines are limited to
using diesel and biodiesel as fuels. All liquid fuels are limited to no
more than 0.0015 percent sulfur by weight.
The proposed general permit includes monitoring that is sufficient
to assure compliance with the emission limitations that apply to the
source, including ensuring the baghouse is operating properly, taking
weekly opacity observations and fugitive emissions surveys and meeting
certain other requirements. The proposed general permit includes
recordkeeping and reporting sufficient to assure compliance with the
emission limitations and monitoring requirements.
3. What geographic restrictions are contained in the HMA general
permit?
The general provisions of the HMA plant draft permit restrict
sources from
[[Page 2558]]
locating in severe and extreme ozone nonattainment areas or serious CO
nonattainment areas.\22\ Because the major stationary source thresholds
are very low in these types of areas, we do not envision that any minor
source HMA plants or SQCS facilities will locate in these areas. Thus,
we did not to address this situation in these general permits. We
request comment on whether the EPA should limit the geographic scope of
eligibility of the general permits in this manner.
---------------------------------------------------------------------------
\22\ Sources can still locate in these areas but would need to
obtain a site-specific NSR permit and may face more stringent
control requirements.
---------------------------------------------------------------------------
B. SQCS Facilities
1. What is a SQCS facility?
A SQCS facility is any non-metallic mineral processing facility
which uses rock crushers, grinding mills, screening operations, bucket
elevators, belt conveyors, bagging operations, storage bins, storage
piles, truck loading stations, or railcar loading stations to process
sand, gravel, or mineral aggregate.\23\
---------------------------------------------------------------------------
\23\ The operations and equipment at a typical SQCS facility are
described in: AP 42, Fifth Edition, Volume I, Chapter 11: Mineral
Products Industry, Chapters 11.19.1, Sand and Gravel Processing, and
11.19.2, Crushed Stone Processing and Pulverized Mineral Processing;
U.S. Environmental Protection Agency; http://www.epa.gov/ttn/chief/ap42/ch11/index.html.
---------------------------------------------------------------------------
The SQCS facilities are part of a larger industrial process where
sand, gravel, rock, and minerals are removed from the earth and
prepared for industrial, commercial and residential use. In sand and
gravel processing, deposits of sand and gravel are mined and processed
with screens, washing, and clarifiers to segregate the material into
different particle sizes. Sometimes facilities use crushing equipment
to reduce particle sizes. In rock crushing operations, drilling and
blasting operations loosen rock, and then a front-end loader or power
shovel loads the rock into large haul trucks that transport the
material to the processing operations. Processing operations may
include: Crushing, screening, size classification, material handling
and storage operations. Rock is loaded into bins and sent through
screens, sorted for size, and conveyed to one or more rock crushers
until all of the raw material is reduced to the desired size. Each
crusher machine has associated screening and conveying equipment. After
crushing, the rock is sorted according to size in screeners and
conveyers that move the rock to storage piles. Front end loaders and
trucks move finished materials offsite. Rock types processed by the
crushed stone industry include: Limestone, granite, dolomite, traprock,
sandstone, quartz, quartzite, and lesser amounts of calcareous marl,
marble, shell, and slate. Electricity for the motors running the
crushers, screens, and conveyors is provided either by grid electric
power or by diesel generators.
Criteria pollutant emissions of concern are primarily PM from
crushing and screening, and PM and NOX from diesel
generators. For sources with available water, water sprays may be used
to control PM emissions. In sand processing, water is typically used in
clarifiers to sort the sand by size, and the sand is processed wet. Dry
PM control methods (baghouses) may also be used to control PM
emissions.\24\
---------------------------------------------------------------------------
\24\ Ibid.
---------------------------------------------------------------------------
2. What is in the proposed SQCS facility general permit?
This proposed general permit would apply to the construction of new
true minor source SQCS facilities or the modification of existing true
minor SQCS facilities, located in Indian country. The proposed general
permit is for a facility that processes non-metallic materials only
(i.e., sand, rock or stone). A source that processes any of the
following is not eligible for coverage under this proposed permit:
Metallic materials; radioactive materials; materials that contain
asbestos; materials intended to be used as fuel; and minerals for
structural clay, clay ceramics, brick, lime manufacturing, phosphate
products, Portland cement, or refractory products.
The draft permit covers emissions from the following equipment at
HMA facilities:
Engines;
Material handling equipment; and
Fuel storage tanks.
The draft permit requires emissions from all crushers, screens, drop
points, and other possible release points to be controlled by wet
suppression, requires fugitive emissions to be controlled by a fugitive
dust control plan, and engines to be controlled to appropriate
standards. Stationary engines are limited to using diesel and biodiesel
as fuels. All liquid fuels are limited to no more than 0.0015 percent
sulfur by weight.
The proposed general permit includes monitoring that is sufficient
to assure compliance with the emission limitations that apply to the
source, including ensuring the wet suppression system is operating
properly, taking weekly opacity observations and fugitive emissions
surveys and meeting certain other requirements. The proposed general
permit includes recordkeeping and reporting requirements sufficient to
assure compliance with the emission limitations and monitoring
requirements.
C. Request for Comment on the Proposed HMA Plant and SQCS Facility
General Permits
We request comment on all aspects of the general permits for HMA
plants and SQCS facilities. We specifically request comment in the
following four areas:
1. Throughput Production Limits as a Surrogate for Annual Ton Per Year
Allowable Emission Limitations
The proposed HMA plant and SQCS facility general permits contain
throughput-based production limits that serve as surrogates for annual
ton per year allowable emission limitations. We discuss the use of
surrogate limits in Section V.E. above. For HMA plants, for production
of hot mix asphalt the draft permit contains separate production
limits:
100,000 tons-per-month based on a 12-month rolling average
from a drum mix asphalt plant; or
33,000 tons-per-month based on a 12-month rolling average
from a batch mix asphalt plant.
For SQCS facilities, the draft permit restricts raw material annual
throughput to 10,500,000 tons based on any continuous rolling 12-month
period. The background information documents for the draft permits
contain the approximate ton per year emission thresholds for which the
throughput limits act as surrogates. The draft permit does not
establish different throughput limits based on the attainment status of
the area. We request comment on our use of throughput limits as a
surrogate for tpy emission limitations for this source category, and on
whether there should be different production throughput limits in
attainment and nonattainment areas.
In establishing specific limits for HMA plants and SQCS facilities,
we considered whether we should compute the production throughput
limits on a ton per year basis, or over a shorter period of time to
assure continuous compliance. For HMA plants, where NOX is
the limiting pollutant, we elected monthly average production limits to
ensure continuous compliance for portable plants that may relocate to
ozone nonattainment areas within the same year. For SQCS facilities,
where PM is the limiting pollutant, we elected to include an annual
limit based on a 12-month rolling total. Nonetheless, we request
comment on whether we should instead establish a monthly total
[[Page 2559]]
emission limitation based on a 30-day rolling total or any other
appropriate averaging period.
In addition to the production throughput limits, each of the draft
permits contains restrictions on the amount of fuel used. For HMA
plants, the combined fuel consumption in all engines and generators,
excluding nonroad mobile engines, may not exceed 12,500 gallons-per-
calendar month if the source is located in an attainment area for
ozone; or 2,500 gallons-per-calendar month if the source is located in
an ozone nonattainment area. (In the HMA permit, fuel combustion is
limited to natural gas, propane, distillate fuel, and biodiesel in the
dryer/mixer and auxiliary heaters and diesel and biodiesel in the
stationary engines and generators.) We are proposing monthly limits on
production and fuel use at HMA plants because NOX emissions
from the dryer and engines are the limiting factor in determining
whether a source qualifies for a general permit. The monthly limits
allow a source to relocate to an area with a different attainment
status and still ensure they are operating as a minor source consistent
with their application. We determined that it would be unnecessarily
complicated for sources to show compliance with two different annual
fuel limits within the same 12-month period (assuming the HMA plant is
co-located with a SQCS facility), since during the previous 11 months
they could have been at different locations. (Below, we discuss how
multiple locations can be handled for the SQCS general permit.) The
monthly limit on fuel use makes demonstrating compliance
straightforward and maintains operational flexibility (since the same
annual production limit applies to attainment and nonattainment areas).
For SQCS facilities, the combined fuel consumption of all engines
and generators, excluding nonroad mobile engines, may not exceed a
range of between 33,000 gallons and 162,000 gallons annually based on a
12-month rolling total for each month, depending on the ozone
attainment status of the area. (In the SQCS permit, fuel combustion in
stationary internal combustion engines is limited to diesel and
biodiesel.) In the case of SQCS facilities, PM emissions from engines
are not a limiting factor in determining whether a facility qualifies
for a general permit so we did not find monthly limits necessary. We
request comment on whether to distinguish the amount of fuel use based
on ozone attainment status, or whether we should set one usage limit
within the stated range for both attainment and nonattainment areas.
The simplicity of a single usage limit may outweigh the benefits of the
flexibility of offering varying limits.
2. Setback Requirement
The draft general permits require HMA and SQCS facilities to locate
at least 150 feet from the nearest property boundary and 1,000 feet
from the nearest residence. These requirements are beyond the
requirements in the EPA's 40 CFR parts 60, 61, and 63 regulations
affecting these source categories. Nonetheless, the states of
Washington \25\ and Alaska \26\ include setback provisions in their
general permits for this source category. We believe that these
requirements will minimize the impact of emissions from these sources
on localized air quality. We request comment on whether we should
include these setback requirements in the final permits to provide
additional protection against adverse impacts to local air quality. In
addition, we request comment on whether there are other neighboring
types of buildings from which the setback should apply (e.g., schools,
nursing homes) and whether to require these facilities to use physical
markers on their property to show compliance with the setback
requirements.
---------------------------------------------------------------------------
\25\ The setback requirement in the Washington's general permit
is based on dispersion modeling for rock crushing facilities with a
high rock throughput rate. For more information, go to: https://fortress.wa.gov/ecy/publications/summarypages/ecy070237.html.
\26\ For information on Alaska's setback requirements, go to:
http://dec.alaska.gov/air/ap/docs/General%20Permit%20Application%20for%20Asphalt%20Plants%2004-12-12.pdf.
---------------------------------------------------------------------------
3. Authorizing Multiple Locations
HMA facilities and SQCS facilities often operate as portable
stationary sources. A facility will locate in a single area for a
specified period of time and then disassemble and relocate to another
area. We structured both draft general permits to accommodate
relocation of a facility. A source may identify multiple sites of
operation in its request for coverage. The reviewing authority will
consider the request for each location, and will specify approval of
one or more of these locations in the approval of the request for
coverage. If the reviewing authority does not approve a specific
location, then the source will need to reapply for coverage under the
general permit or for a site specific permit before relocating to this
site. The general permits also require a source to submit a
notification to the reviewing authority each time it relocates to a
pre-approved site. We request comment on the use of these general
permits to authorize relocation of a facility to pre-approved site
locations. In addition, because these two types of facilities can co-
locate at the same site, we seek comment on whether we should issue
general permits that cover both source categories within one permit, in
lieu of two separate permits, or in addition to two separate permits.
If we finalize such an approach, we propose to include all the
requirements proposed for the separate permits in a single permit, but
we seek comment on whether the combined permit should include any
additional or different requirements.
4. Spark-Ignition Engines
The draft general permits for both HMA and SQCS facilities include
control measures for a number of different engine types. We did not
include spark-ignition engine control measures in either general
permit, because we do not believe that HMA or SQCS facilities commonly
use these types of engines, and, as we discuss above, we precluded use
of any fuel other than diesel or biodiesel in stationary internal
combustion engines. We request comment on this conclusion. If
commenters indicate that spark ignition engines should be regulated
under the general permits, then we may include emission limitations
comparable to the levels established for other type of engines in the
final general permits.
D. Auto Body Repair and Miscellaneous Surface Coating Operations
1. What is an auto body repair and miscellaneous surface coating
operation?
An auto body shop repairs, repaints, and/or customizes passenger
cars, trucks, vans, motorcycles, and other mobile equipment capable of
being driven or drawn on the highway. Auto body refinishing shops
involve cleaning the auto body surface to ensure proper adhesion of the
coating, priming and sealing the surface, applying a topcoat, and
cleaning of the spray equipment. Coating application equipment includes
preparation stations, spray booths, spray guns, and spray gun cleaning
equipment. Some facilities are equipped with heating units to heat the
air in the drying booth or to maintain a constant shop temperature
during cold months. The majority of these operations occur at small
body shops that repair and refinish automobiles. The activities include
sanding, cleaning, spray-applying coating, and cleaning spray
equipment, all of which may release pollutants into the air.
[[Page 2560]]
Miscellaneous surface coating operations are those that involve the
spray application of coatings to miscellaneous parts and/or products
made of metal or plastic, or combinations of metal and plastic. These
activities include:
Paint stripping for the removal of dried paint (including,
but not limited to, paint, enamel, varnish, shellac, and lacquer) from
wood, metal, plastic, and other substrates;
Spray application of coatings to motor vehicles and mobile
equipment including operations that are located in stationary
structures at fixed locations, and mobile repair and refinishing
operations that travel to the customer's location; and
Spray application of coatings to a plastic and/or metal
substrate on a part or product, except spray coating applications that
meet the definition of facility maintenance or space vehicle.
The coating application operations include washes, primers, primer
surfacers, primer sealers, and topcoats. Coatings are applied using a
hand-held device that creates an atomized mist of coating and deposits
the coating on assembled motor vehicles and mobile equipment.
The pollutants of concern for auto body repair and surface coating
operations are VOCs and hazardous air pollutants (HAP) from the use of
solvents and coatings. Particulate matter emissions are also emitted
from spray coating operations. Paints, coatings, and the solvents used
for paint gun clean-up are the main sources of VOCs in auto body shops.
Emissions are typically controlled through use of lower-VOC coatings,
increased transfer efficiency of spray guns, minimizing solvent
evaporation during clean-up and other best practices, such as closing
all containers of painting materials immediately after use. Particulate
matter emissions are also emitted from spray coating operations.
Because spray coating operations are normally performed in enclosed
spray booths and controlled by dry filters or other equivalent control
devices, PM emissions from spray coating operations are not significant
if the spray booths and the associated control devices are operated
properly. If a facility contains fuel combustion heating units, there
are associated combustion emissions from those units.
Coatings processes also include degreasing. Solvent degreasing (or
solvent cleaning) is the physical process of using organic solvents to
remove grease, fats, oils, wax or soil from various metal, glass, or
plastic items. The types of equipment used in this method are
categorized as cold cleaners, open top vapor degreasers, or
conveyorized degreasers. The general permit only allows for the use of
cold cleaners that are batch loaded and non-boiling solvent degreasers.
These processes usually provide the simplest and least expensive method
of metal cleaning. Maintenance cold cleaners are smaller, more
numerous, and generally use petroleum solvents such as mineral spirits
(petroleum distillates and Stoddard solvents). Manufacturing cold
cleaners use a wide variety of solvents, which perform more specialized
and higher quality cleaning with about twice the average emission rate
of maintenance cold cleaners. Some cold cleaners can serve both
purposes.
Cold cleaner operations include spraying, brushing, flushing, and
immersion. In a typical maintenance cleaner, dirty parts are cleaned
manually by spraying and then soaking in the tank. After cleaning, the
parts are either suspended over the tank to drain or are placed on an
external rack that routes the drained solvent back into the cleaner.
The cover is intended to be closed whenever parts are not being
processed in the cleaner. Typical manufacturing cold cleaner operations
vary widely in design, but there are two basic tank designs: the simple
spray sink and the dip tank. Of these, the dip tank provides more
thorough cleaning through immersion, and often is made to improve
cleaning efficiency by agitation. Small cold cleaning operations may be
numerous in urban areas.
2. What is in the proposed auto body repair and miscellaneous surface
coating operations general permit?
This proposed general permit would apply to the construction of
new, true minor source auto body repair and miscellaneous surface
coating facilities or the modification of existing, true minor source
facilities, located in Indian country. Surface coating facilities that
are major sources under 40 CFR part 63, and are subject to the
requirements of certain National Emission Standards for Hazardous Air
Pollutants (NESHAP),\27\ are not eligible for coverage under this
general permit.\28\ The Maximum Achievable Control Technology (MACT)
standards in these regulations cover a wide array of surface coating
operations, each with a different set of emission standards for the
various coatings typically used by the particular source category, some
of which may require add-on controls. Creating a general permit that
covers all of these surface coating operations--as required by 40 CFR
49.154(c)(4)--would be cumbersome and likely create a general permit
that would be confusing to the permittee. We believe auto body repair
and miscellaneous surface coating operations are a typical type of true
minor surface coating operation such that it is a good candidate for a
general permit.
---------------------------------------------------------------------------
\27\ The relevant NESHAPs are: Subpart II--National Emission
Standards for Hazardous Air Pollutants: Shipbuilding and Ship
Repair; Subpart IIII--National Emission Standards for Hazardous Air
Pollutants: Surface Coating of Automobiles and Light-Duty Trucks;
Subpart KKKK--National Emission Standards for Hazardous Air
Pollutants: Surface Coating of Metal Cans; Subpart MMMM--National
Emission Standards for Hazardous Air Pollutants for Surface Coating
of Miscellaneous Metal Parts and Products; Subpart NNNN--National
Emission Standards for Hazardous Air Pollutants: Surface Coating of
Large Appliances; Subpart OOOO--National Emission Standards for
Hazardous Air Pollutants: Printing, Coating, and Dyeing of Fabrics
and Other Textiles
Subpart PPPP--National Emission Standards for Hazardous Air
Pollutants for Surface Coating of Plastic Parts and Products;
Subpart QQQQ--National Emission Standards for Hazardous Air
Pollutants: Surface Coating of Wood Building Products; Subpart
RRRR--National Emission Standards for Hazardous Air Pollutants:
Surface Coating of Metal Furniture; and Subpart SSSS--National
Emission Standards for Hazardous Air Pollutants: Surface Coating of
Metal Coil.
\28\ Due to the surface coating-related requirements in a
NESHAP, it is possible that a source could be a major source for
HAPs but a minor source for regulated NSR pollutants. However, for
simplicity, we are proposing to exclude major HAP sources.
---------------------------------------------------------------------------
We request comment on limiting eligibility of the general permit to
true minor sources that are not major sources of HAP, or whether there
are any terms or conditions we could add to the final permit that would
ensure both compliance with the general permit and with the MACT
standards.
The draft permit requires that all spray applications of coatings
must be performed using high efficiency spray guns in a spray booth
controlled by exhaust filters. We assumed that only batch-loaded cold
cleaning degreasers were used at these types of facilities. The
requirements for cold solvent degreasing include several work practice
standards to ensure VOC emissions are minimized, including: keeping the
degreaser cover closed at all times, except during parts entry and
removal; the degreaser should be free of cracks, holes and other
defects; all waste solvents must be properly stored and identified in
sealed containers; and solvent flow must be directed downward.
The proposed permit includes monitoring that is sufficient to
assure compliance with the emission limitations that apply to the
source, including requiring monitoring for overspray, assuring that
pressure drop
[[Page 2561]]
across the exhaust filters does not exceed manufacturers'
recommendations and inspecting solvent degreasers for leaks and cracks
prior to use. The proposed permit includes recordkeeping and reporting
sufficient to assure compliance with the emission limitations and
monitoring requirements.
3. Request for Comment on the Proposed Auto Body Repair and
Miscellaneous Surface Coating Operations General Permit
We request comment on all aspects of the general permit for auto
body repair and miscellaneous surface coating operations. We
specifically request comment in the following two areas:
(a) Surrogate Annual Allowable Emission Limitations
The EPA is also proposing to include an annual allowable emission
limitation for auto body repair and miscellaneous surface coating
operations source category. This general permit would apply to the
construction of new facilities proposing to locate in Indian country or
the modification of existing auto body repair and miscellaneous surface
coating operations located in Indian country. In attainment areas of
Indian country, the draft general permit includes an upper throughput
limit for VOC containing materials (e.g., coatings, thinners, and
clean-up solvents) not to exceed 5,000 gallons per year (gpy) based on
a 12-month rolling total. This surrogate emission limitation equates to
approximately 25 tpy or less of VOCs.\29\ In ozone nonattainment areas
of Indian country, the draft general permit includes an upper
throughput limit for VOC containing materials (e.g., coatings,
thinners, and clean-up solvents) not to exceed 900 gpy based on a 12-
month rolling total. This surrogate emission limitation equates to 7
tpy or less of VOCs.\30\ Finally, we request comment on the
appropriateness of establishing different limitations based on the
attainment status of the area and whether the specified limitations
should be slightly higher or slightly lower.
---------------------------------------------------------------------------
\29\ Information on the source of these thresholds is available
at: Background Document, Minor Source Auto Body Repair and
Refinishing Shops General Permit and Permit by Rule, Docket ID No.
EPA-HQ-OAR-2011-0151, http://www.epa.gov/air/tribal/tribalnsr.html.
\30\ Information on the source of these thresholds is available
at: Background Document, Minor Source Auto Body Repair and
Refinishing Shops General Permit and Permit by Rule, Docket ID No.
EPA-HQ-OAR-2011-0151, http://www.epa.gov/air/tribal/tribalnsr.html.
---------------------------------------------------------------------------
(b) Covering Both Auto Body Repair and Miscellaneous Surface Coating
Operations
As currently structured, both auto body repair shops and
miscellaneous surface coating operations are eligible to apply for
coverage under the general permit. We think these types of emissions
activities qualify as similar sources because (1) they both use the
same type of equipment (such as spray guns) and materials (such as
paint) that have similar forms of emissions with a similar overall
emissions potential and (2) they use similar approaches to minimizing
emissions. We request comment on treating these emissions activities as
similar sources and on regulating both activities within the same
general permit.
E. GDFs
1. What is a GDF?
A GDF is any stationary facility that dispenses gasoline into the
fuel tank of a motor vehicle, nonroad vehicle or equipment, including a
nonroad vehicle or nonroad engine used solely for competition.\31\ It
should also be noted that a GDF could also include equipment that
dispenses diesel fuel (diesel is discussed further below). Furthermore,
a GDF could be an operation supporting other activities at a facility
that otherwise requires a permit.\32\
---------------------------------------------------------------------------
\31\ A more formal regulatory definition of GDF can be found at
40 CFR 63.11132.
\32\ Under the general permit and permit by rule programs, such
a source would be considered a minor source and potentially eligible
for the permit provided the PTE of all existing, new and modified
emission units at the stationary source were below the major source
thresholds for all regulated NSR pollutants.
---------------------------------------------------------------------------
Gasoline is delivered by tank trucks to GDFs and then transferred
to highway motor vehicles and nonroad equipment and engines. GDFs
include all retail outlets such as traditional gasoline service
stations, convenience stores, truck stops, and hypermarkets (e.g.,
warehouse clubs and big box stores), marinas, as well as private and
commercial outlets, such as centrally-fueled fleets, government
operations, and private businesses such as farms and landscaping
operations. This does not include airports offering aviation gasoline
or mobile fueling capabilities.
Gasoline vapors are released during the transfer of gasoline from
tank trucks to stationary gasoline storage tanks and during the
refueling of vehicles and equipment.\33\ Gasoline vapors are the major
air pollution concern associated with gasoline dispensing and handling
facilities because they contain VOCs and HAPs such as aromatic
compounds and isooctane.\34\
---------------------------------------------------------------------------
\33\ Some vapors can also be released due to spillage by vehicle
operators as vehicles are fueled.
\34\ For more information, go to: http://www.epa.gov/ttn/chief/eiip/techreport/volume03/iii11_apr2001.pdf.
---------------------------------------------------------------------------
The EPA's emissions factor document, AP-42, has traditionally
divided VOC emissions from GDFs into two basic segments of operation:
Stage I and Stage II.\35\ Stage I generally refers to the transfer of
gasoline from the delivery truck to the aboveground storage tank (AST)
or underground storage tank (UST). Fuel storage tanks are generally,
but not always, cylindrical in shape, and vary in volume from 250
gallons (approximately 1,000 liters) to 30,000 gallons. Volumes of 250
to 1,000 gallons are most common for ASTs and 6,000 to 12,000 gallons
are most common USTs. Stage II refers to gasoline in storage in these
tanks and/or its transfer to a vehicle or equipment fuel tank through a
pump and dispenser.
---------------------------------------------------------------------------
\35\ For more information, go to: AP 42, Fifth Edition, Volume
I, Chapter 5: Petroleum Industry; U.S. Environmental Protection
Agency; http://www.epa.gov/ttn/chief/ap42/ch05/index.html.
---------------------------------------------------------------------------
VOC emissions control technology exists and is required for Stage I
and Stage II operations. Stage I vapor recovery is a control method to
capture gasoline vapors that are released when gasoline is delivered by
a tank truck to a storage tank located at a GDF. Instead of being
released to the air, the gasoline vapors from filling the tank are
captured and returned to the tank truck as the storage tank is being
filled with fuel. From there, the vapors are transported back to the
gasoline terminal vapor processor for recovery or destruction. Because
of the GDF NESHAP requirements (found at 40 CFR part 63, Subpart
CCCCCC), all GDFs dispensing more than 1,200,000 gpy were required to
have Stage I controls in place in January 2011, with lesser
requirements in the same timeframe for GDFs with gasoline throughputs
between 120,000 gpy and 1,200,000 gpy.\36\ Stage I controls were
commonly in place at many larger throughput GDFs prior to 2000. There
are no such requirements for diesel fuel.
---------------------------------------------------------------------------
\36\ Certified vapor recovery systems include hoses, nozzles,
processors, and other equipment that create a closed system which
returns gasoline vapor back to the underground storage tank and then
back to the truck that delivers the gasoline to your station. The
system and equipment are designed to capture vapor before it is
released to the air.
---------------------------------------------------------------------------
Stage II vapor recovery captures gasoline vapor that would
otherwise escape into the air when motorists refuel their vehicles.
Section 182(b)(3) of the CAA, 42 U.S.C. 7511a(b)(3), required pump-
based Stage II vapor recovery for some GDFs located in
[[Page 2562]]
``moderate'' or above ozone nonattainment areas. Section 202(a)(6) of
the CAA, 42 U.S.C. 7521(a)(6), required the EPA to develop standards
for vehicle-based onboard vapor recovery (ORVR) controls on light-duty
vehicles to capture these emissions. Section 202(a)(6) of the CAA also
states that the section 182(b)(3) pump-based Stage II requirement shall
not apply in moderate nonattainment areas after ORVR standards are
promulgated, but would be required for serious, severe, or extreme
ozone nonattainment areas.\37\ On April 16, 1994, the EPA published
regulations requiring the phase-in of ORVR controls on new passenger
cars and light trucks.\38\ These controls were required on all new
gasoline-powered motor vehicles, not just those in ozone nonattainment
areas.
---------------------------------------------------------------------------
\37\ For more information, see: ``Widespread Use for Onboard
Refueling Vapor Recovery and Stage II Waiver,'' U.S. Environmental
Protection Agency, 77 FR 28772, May 16, 2012, http://www.gpo.gov/fdsys/pkg/FR-2011-07-15/html/2011-17888.htm. The rulemaking
documents and supporting analyses are available at EPA public docket
EPA-HQ-OAR-2010-1076.
\38\ These requirements were ultimately extended to all complete
heavy-duty gasoline-powered vehicles (HDGVs) with a gross vehicle
weight rating (GVWR) less than 10,000 pounds and have recently been
proposed to extend to all complete HDGVs with a GVWR up to 14,000
pounds.
---------------------------------------------------------------------------
In addition, the CAA provides that the EPA may revise or waive the
pump-based Stage II control requirements of section 182(b)(3) for
serious or above ozone nonattainment areas after the EPA determines
that ORVR control systems are in ``widespread use'' throughout the
motor vehicle fleet. The EPA has determined that vehicle-based ORVR
refueling emission control systems were in widespread use in the motor
vehicle fleet as of May 9, 2012.\39\ This determination triggered the
provision of section 202(a)(6) of the CAA, which waives the section
182(b)(3) Stage II requirement for serious or above ozone nonattainment
areas. Under this waiver, states are no longer required to have pump-
based Stage II vapor recovery systems for control of vehicle refueling
emissions under section 182 (b)(3).\40\
---------------------------------------------------------------------------
\39\ ``Widespread Use for Onboard Refueling Vapor Recovery and
Stage II Waiver,'' U.S. Environmental Protection Agency, 77 FR
28772, May 16, 2012, http://www.gpo.gov/fdsys/pkg/FR-2012-05-16/html/2012-11846.htm.
\40\ If a state submits a State Implementation Plan (SIP)
revision to remove Stage II requirements from a previously approved
SIP, it would need to demonstrate that the revision meets the
requirements of sections 110(l) of the CAA as well as sections 193
and 184(b)(2), if applicable.
---------------------------------------------------------------------------
2. What impact will the GDF National Emissions Standard for Hazardous
Air Pollutants and onboard refueling vapor recovery control systems
have on emissions from GDFs?
The GDF NESHAP and ORVR controls have a significant impact on
lowering the VOC emissions levels from GDFs. GDF NESHAP requirements
address Stage I emissions for all but the lowest throughput GDFs. ORVR
controls and the gasoline dispensing rate limits which the EPA put in
place in 1996 have significantly reduced the VOC emission rates. When
fully phased-in, ORVR will reduce Stage II vapor displacement emissions
by about 98 percent and fuel spillage by 50 percent.\41\
---------------------------------------------------------------------------
\41\ These values are discussed more fully in EPA memoranda,
``Updated Data for ORVR Widespread Use Assessment,'' February 29,
2012 and ``Onboard Refueling Vapor Recovery Widespread Use
Assessment,'' June 9, 2011. Both are available in: Docket EPA-HQ-
OAR-2010-1076.
---------------------------------------------------------------------------
Using this information, Table 3 illustrates how the minor source
NSR VOC emission permitting thresholds of 2 and 5 tpy translates into
the equivalent volumes of gasoline dispensed by a GDF on both a monthly
and yearly basis based on the control efficiencies for the GDF NESHAP
and ORVR regulations. The 2 tpy value applies to any area classified as
ozone nonattainment (marginal, moderate, serious, severe, or extreme)
at the time the permit is being submitted and the 5 tpy applies to
areas meeting the ozone NAAQS at that time. It includes the basic Stage
I and Stage II emission sources plus the impacts that the GDF NESHAP
and the increasing percentage of vehicles with ORVR controls will have
on refueling emissions from GDFs (assuming pump-based Stage II vapor
recovery is not in place). In this table, the displacement VOC emission
rate in pounds/1,000 gallons depends on the gasoline Reid Vapor
Pressure (RVP), the dispensed fuel temperature, and the difference
between the temperature of the fuel in the tank and the dispensed fuel.
For these purposes, the EPA has used 7 pounds per square inch (psi) RVP
and temperatures representative of the summertime western U.S. for
ozone non-attainment areas and 10 psi RVP and national average
summertime temperatures for all other areas in calculating the
uncontrolled displacement VOC emission rate in pounds/1,000 gallons.
This yields values of about 7.5 and 10.8 pounds/1,000 gallons,
respectively.\42\
---------------------------------------------------------------------------
\42\ For information on how these values were determined, see
``Calculation of Emissions from GDFs,'' Memorandum from Glenn W.
Passavant to Public Docket EPA-HQ-OAR-2011-0151, September 24, 2012,

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
As shown in row 1b, the EPA estimates that ORVR will control 82
percent of motor vehicle gasoline refueling emissions in 2014. A GDF in
an ozone nonattainment area could dispense approximately 2.1 million
gpy before reaching the 2 tpy emissions threshold. As seen in row 1c,
however, that same GDF could dispense approximately 3.5 million gpy in
2020 because 92 percent of refueling
[[Page 2563]]
emissions will be controlled by vehicles equipped with ORVR.
In row 2b, the EPA estimates that a GDF in an ozone attainment area
could dispense approximately 4 million gpy in 2014 before reaching the
5 tpy emissions threshold for ozone in a PSD area. As seen in row 2c,
however, a GDF in an attainment area could dispense about 7.1 million
gpy in 2020 because 92 percent of gasoline refueling emissions are
expected to be controlled by ORVR. The calculations in Table 3 are
snapshots for the various calendar years. Based on the PTE calculator,
the gpy or gpm values for any given permit depend on the geographic
location (attainment or non-attainment area) and the year in which
coverage under the permit is requested.
The average GDF has a throughput of 1.5 million gpy; thus, many
GDFs have throughputs below the 2014 gpy values listed in Table 3. If a
GDF has projected emissions below the 2 tpy and 5 tpy minor NSR
emissions thresholds for ozone nonattainment and attainment areas
specified in the Indian Country Minor NSR rule, it does not need to
obtain a pre-construction permit but may still be required to meet the
GDF NESHAP requirements of 40 CFR part 63, Subpart CCCCCC and those
proposed below for ASTs. While it is possible that a large and very
active GDF could exceed the minor NSR emissions thresholds for ozone
nonattainment and attainment areas (2 and 5 tpy, respectively) and,
thus, be subject to the Minor NSR rule permit requirements, it is very
unlikely that a single GDF could dispense enough fuel to exceed a 10
tpy level, which is the strictest VOC emissions threshold for a major
source in a nonattainment area. The average refueling event is 10 to 11
gallons. If, for example, one simply multiplies the gpy entries in the
Table 3 rows (1b) by a value of 5 tpy and divides by 11 gallons per
minute, the result is over approximately 950,000 refueling events per
year at one GDF. There are practical limitations on GDF acreage, as
well as vehicle transit and tanker truck deliveries, which serve as a
practical cap on the number of refueling events per year. Exceeding the
10 tpy limit in ozone nonattainment areas in 2014 would require over
2,600 gasoline refueling events per day, which is practically unlikely
at even the largest and busiest GDFs.
Thus, considering the physical limitations on GDFs and the
emissions impact of ORVR, we propose that for most areas there is no
need for numerical limits on the quantity (throughput) or rate (tpy) of
emissions for GDFs as it is practically not possible to become a major
source. However, to provide extra air quality protection, we are
proposing to have a surrogate emission limitation for serious, severe
or extreme ozone nonattainment areas. For these areas, the draft permit
requires the source to limit annual gasoline surrogate throughput to 10
million gallons or less based on a 12-month rolling total for each
month. This surrogate throughput limit is set at a level intended to
ensure that GDFs under this general permit and permit by rule remain
minor sources and below the lowest major source threshold for extreme
ozone nonattainment areas of 10 tpy.
3. Treatment of Diesel Fuel
It is common for facilities with gasoline dispensing operations to
also dispense diesel fuel to autos, light trucks, heavy-trucks, and
nonroad equipment. However, the true vapor pressure of diesel fuel is
only about 0.2 percent of the 7 psi RVP gasoline at 70[emsp14][deg]F.
Thus, while Stage I and Stage II type emissions occur with diesel fuel
dispensing operations, they are very low in comparison and no Stage I
or Stage II controls are required. For completeness, the PTE calculator
provided as part of this NPRM includes diesel emissions but these in
total would be very small in comparison to gasoline vapor emissions.
This PTE could also help to inform calculations of total VOC emissions
from a facility where a GDF is only part of the overall VOC emissions
from the source used in assessing the permit application.
4. What are the requirements for the proposed general permit for GDFs
in serious, severe, and extreme ozone nonattainment areas?
We are proposing the following additional requirements, as
discussed below, for GDFs in Indian country that are located in
serious, severe, and extreme ozone nonattainment areas. Currently, all
of the areas of Indian country located in serious, severe, and extreme
ozone nonattainment areas are located in California, but that situation
could change in the future.\43\ We examined the GDF requirements of the
California Air Resources Board (ARB) and the six California air quality
management and air pollution control districts (collectively AQMDs)
that are designated serious, severe, or extreme for ozone nonattainment
and have areas of Indian country within their boundaries.\44\
---------------------------------------------------------------------------
\43\ For more information, see: ``Air Quality Designations for
the 2008 Ozone National Ambient Air Quality Standards,'' 77 FR
30088, May 21, 2012, http://www.epa.gov/airquality/ozonepollution/designations/2008standards/final/tribalf.htm.
\44\ These include El Dorado County AQMD, San Joaquin Valley
Unified APCD, Placer County APCD, South Coast AQMD, Mojave Desert
AQMD, and Yolo-Solano AQMD.
---------------------------------------------------------------------------
California ARB adopted regulations for control of standing loss
control (SLC) VOC emissions from ASTs.\45\ Emissions of this type are
not included in the GDF NESHAP requirements. The test procedures and
SLC emission standard (0.57 lbs/1,000 gallons ullage/day) for these
requirements potentially cover all ASTs regardless of volume.\46\
Systems can be certified to the SLC emission standards either by design
or performance as discussed in ARB CP-206.\47\ Responding to these
requirements generally involves the use of one of several techniques to
treat the tank in such a way as to reduce the diurnal temperature
changes in the fuel in the AST and to add a pressure vacuum (p/v) valve
to address AST venting. These requirements became applicable to
existing ASTs in California in April 2009, and to new ASTs (including
major modifications) in April 2013. They apply to ASTs in the
individual air districts in California if the ARB rule is adopted by
that air district.\48\ All of the AQMDs in serious, severe, and extreme
ozone nonattainment areas in California have adopted the SLC
requirements, but have granted exemptions for tanks of 250 gallons
capacity or less. Thus, to address ozone air quality and as a matter of
equity, the EPA is requesting comment on whether the final permits
should include these SLC requirements. If we include these
requirements, then
[[Page 2564]]
we would delay the effective date of compliance until January 1, 2014.
---------------------------------------------------------------------------
\45\ Standing losses are gasoline vapor emissions that occur
whenever the gasoline evaporates during periods of no gasoline
transfer. These evaporative emissions escape through open vent pipes
and leaks in the AST. They occur when internal tank pressure
increases as a result of diurnal temperature changes. Standing
losses from ASTs vary based on the different tank configurations,
fill levels, and volumes.
\46\ For more information on test procedures and standards, see:
http://www.arb.ca.gov/regact/2007/ast07/ast07.htm. Most notably,
refer to the ISOR and TP-206.1, TP-206.2, and CP-206.
\47\ See http://www.arb.ca.gov/testmeth/vol2/cp-206.pdf,
Certification Procedure for Vapor Recovery Systems at Gasoline
Dispensing Facilities Using Aboveground Storage Tanks, CP--206,
California Air Resources Board, Adopted: May 2, 2008.
\48\ The EPA has approved requirements for aboveground storage
tanks with capacity greater than 250 gallons for Sacramento
Metropolitan AQMD (Revisions to the California State Implementation
Plan, San Diego APCD,
Northern Sierra AQMD, and Sacramento Metropolitan AQMD; January
7, 2013; 78 FR 897) and San Joaquin Valley Unified APCD (Revisions
to the California State Implementation Plan, Northern Sierra Air
Quality Management District and San Joaquin Valley Unified Air
Pollution Control District; October 30, 2009; 74 FR 56120).
---------------------------------------------------------------------------
We would, though, propose to exempt any AST with a volume equal to
or less than 250 gallons. This is consistent with the current NESHAP
and California air district rules. Tanks not qualifying for this
exemption would need to meet the proposed applicable NESHAP
requirements, as well as the SLC requirements as discussed above,
including the reporting requirements.
Since these ASTs are all expected to be in California, we seek
comment as to whether the EPA should simply adopt the SLC and ARB Phase
I requirements for ASTs for new or reconstructed ASTs with a volume
greater than 250 gallons \49\ in lieu of SLC and the EPA Stage I
requirements as prescribed in 40 CFR part 63, subpart CCCCCC. This
approach could be more efficient and offer wider availability of ASTs
that meet California emissions requirements. Furthermore, the EPA is
asking for comment on whether the exemption threshold should be set at
250 gallons or less or at 1,000 liters or less. An AST with 1,000 liter
volume is the equivalent of about 265 gallons. An uncontrolled 250
gallon AST which is splash refilled monthly would emit about 62 pounds
per year. A 265 gallon AST would emit 6 percent more.
---------------------------------------------------------------------------
\49\ See California ARB certification requirement (CP-206) and
test procedures (TP-206.1. TP-206.2. and TP-206.3) for more detail
on these requirements. These are available at http://www.arb.ca.gov/vapor/vapor.htm.
---------------------------------------------------------------------------
Finally, we note that many of the California Air Districts allow
exemptions for ASTs when 50 percent or more of the throughput is
involved in supporting husbandry activities (e.g., ranching and
farming). Since we are not proposing such a provision, this creates a
question as to whether new SLC controlled tanks would be available in
some tank sizes such as 250 gallons and what would be the control costs
if they are required only in areas of Indian country. We request
comment on these two points.
5. What type of source may apply for coverage under the proposed GDF
general permit?
This proposed general permit covers construction of new true minor
source GDFs to be located in Indian country, or the modification of
existing true minor source GDFs in Indian country. The general permit
is available to any facility that qualifies as a GDF. There are no
limitations on the eligibility of GDFs to apply for this general
permit. The permit contains requirements for proper design,
construction, installation and operation of vapor balance systems for
the loading of gasoline into storage tanks and daily storage therein.
It applies to GDFs with USTs and/or ASTs. It potentially includes
facilities dispensing gasoline, gasoline and diesel fuel, or diesel
fuel only.
6. Request for Comment on the Proposed GDF General Permit
We request comment on all aspects of the general permit for GDFs.
We specifically request comment in the following two areas:
a. Should the EPA establish an annual allowable emission limitation?
The draft permit does not contain an annual ton per year allowable
emission limitation or a surrogate emission limitation, unless a source
locates in a serious, severe or extreme ozone nonattainment area.
Because of the effectiveness of ORVR and other practical constraints on
emissions from GDF operations, for most areas we do not believe that it
is necessary to establish an annual allowable emission limitation to
properly regulate the construction or modification and then operation
of true minor GDF sources. We request comment on this conclusion. If
the EPA were to include a throughput emission limitation, we would
establish this limit just below the major source threshold for VOC. The
throughput emission limitation would be calculated as the product of
emissions factors and the volume of annual gasoline throughput that
corresponds to the ton per year of the major source threshold. As the
implementation of ORVR continues, in the future there would be little
need to adjust throughput emission limitation because of the practical
limitations on how much gasoline a GDF can process.
However, if a source locates in an extreme ozone nonattainment
area, then the draft permit requires the source to limit annual
gasoline throughput to 8 million gallons or less based on a 12-month
rolling total for each month. This throughput limit is set at a level
intended to ensure that GDFs under this general permit or permit by
rule remain minor sources and below the major source threshold for
extreme ozone nonattainment areas of 10 tpy. We request comment on the
need for this additional requirement in serious and above ozone
nonattainment areas.
b. Should proposed standing loss control requirements apply to GDFs in
Indian country in potential future serious, severe, and extreme ozone
nonattainment areas outside of California?
The EPA is proposing that new and modified ASTs greater than 250
gallons to be located in Indian country in California meet proposed SLC
emission control requirements. This is consistent with air quality
needs and is the same as required for ASTs outside of Indian country in
California. As discussed above, compliant ASTs are expected to be
readily available in California. This may not necessarily be the case
outside of California, however, as no other state has adopted SLC
requirements. Given this potential disparity in technology
availability, the EPA asks for comment on applying SLC requirements in
areas outside of California. The EPA also asks if this requirement
should be linked to whether the GDF would exceed the minor NSR
thresholds (2 and 5 tpy) for ozone attainment and nonattainment areas,
respectively, if SLC emissions were not included.\50\
---------------------------------------------------------------------------
\50\ Uncontrolled SLC emissions = 5.7 pounds/1,000 gallons of
ullage per day. Normally, an AST would have ullage of 45 percent of
capacity on average, assuming it is filled to capacity each time it
drops to 10 percent of capacity.
---------------------------------------------------------------------------
F. Petroleum Dry Cleaning Facilities
1. What is a petroleum dry cleaning facility?
A petroleum dry cleaning facility can consist of dry cleaning
dryers, washers, filters, stills, settling tanks, and boilers. The dry
cleaning industry is a service industry involved in the cleaning of
articles ranging from personal clothing to mops and mats. Dry cleaning
involves the cleaning of fabrics with nonaqueous organic solvents. The
dry cleaning process includes three steps: (1) Washing the fabric in
solvent; (2) spinning to extract excess solvent; and (3) drying by
tumbling in a hot air stream. There are two general types of cleaning
fluids used in the industry: petroleum solvents and synthetic solvents.
Petroleum solvents, such as Stoddard or 140-F, are combustible
hydrocarbon mixtures similar to kerosene. Synthetic solvents or
halogenated hydrocarbons, such as perchloroethylene (``perc'' or PCE),
are nonflammable.
Petroleum dry cleaning operations are similar to detergent and
water wash operations. There are two basic types of dry cleaning
machines, transfer and dry-to-dry machines. Transfer machines
accomplish washing and drying in separate machines. Dry cleaning as a
[[Page 2565]]
batch process in transfer machines can result in a large amount of VOC
or HAP emissions due to vaporization of solvent during the transfer
process. Dry-to-dry machines are single units that perform all of the
washing, extraction, and drying operations. Since cleaning and drying
take place in the same compartment of dry-to-dry machines, significant
amounts of VOC and HAP emissions are eliminated from dry-to-dry
machines.\51\ Most petroleum dry cleaning machines in operation today
are dry-to-dry machines.\52\ Dryers, solvent filtration and
distillation systems, and miscellaneous (fugitive) sources are the
major contributors of VOC emissions in a dry cleaning plant. Most
petroleum dry cleaning facilities have one or two small natural gas
fired steam boilers. VOC emissions from combustion are typically not a
significant concern at petroleum dry cleaning facilities. The EPA has
issued a New Source Performance Standard (NSPS) for petroleum dry
cleaning facilities \53\ and a NESHAP for perc.54 55

cleaning dryer to be a solvent recovery dryer, petroleum solvent
filters to be drained for 8 hours prior to removal, and the
manufacturer to put a specific label on dryers requiring leak
inspections and repairs. The general permit includes the requirement
to use a solvent recovery dry. The general permit does not include
the work practice standard for petroleum solvent filters as it is
EPA's more recent experience that solvent filters are an antiquated
practice and no longer is use. The general permit also does not
include the labeling requirement for manufacturers, but does include
the same monitoring requirements that must be included on the label.
---------------------------------------------------------------------------
2. What is in the proposed petroleum dry cleaning facilities general
permit?
This proposed general permit would apply to the construction of new
(or modification of existing) true minor source petroleum dry cleaning
facilities located in Indian country. The sources in question only use
petroleum solvent in dry cleaning dryers, washers, filters, stills and
settling tanks. The draft permit requires that all petroleum dry
cleaning dryers must be solvent recovery dryers and that care must be
taken to ensure equipment is operated properly and solvents are
properly stored. Facilities that use synthetic solvents are not
eligible for coverage under this general permit. The permit contains
requirements for:
Material use;
Dryers;
Solvent storage;
Solvent recovery;
Button, washer and line traps;
Access doors and other equipment; and
Used material storage.
The proposed permit includes monitoring that is sufficient to
assure compliance with the emission limitations that apply to the
source, including requiring each petroleum solvent dry cleaning dryer
to be inspected every 15 calendar days for evidence of leaks and all
vapor or liquid leaks to be repaired within the subsequent 15 calendar
day period. The proposed permit includes recordkeeping and reporting
sufficient to assure compliance with the emission limitations and
monitoring requirements.
For sources located in severe or extreme ozone nonattainment areas,
the permit also requires that, no less frequently than monthly, the
owner or operator shall inspect the dry cleaning system for liquid and
vapor leaks, including, but not limited to, the following:
Hose connections, unions, couplings, valves, and flanges;
Machine door gasket and seating of the machine cylinder;
Filter head gasket and seating;
Pumps;
Base tanks and storage containers;
Water separators;
Filter sludge recovery;
Seals and gaskets of distillation unit(s);
Diverter valves;
Saturated lint from lint trap basket;
Button trap lid;
Seals, gaskets and the diverter valve of the refrigerated
condenser;
Exhaust stream ducts;
Lint trap ducts; and
Gaskets and ducts of the carbon adsorber.
3. Request for Comment on the Proposed Petroleum Dry Cleaning
Facilities General Permit
We request comment on all aspects of the general permit for
petroleum dry cleaning facilities. We specifically request comment in
the following two areas:
a. Surrogate Annual Allowable Emission Limitations
The petroleum dry cleaning general permit contains material use
limits that serve as surrogate annual ton per year allowable emission
limitations. We discuss the use of surrogate limits in Section V.E.
above. If a source locates in an ozone attainment or unclassifiable
area of Indian country, the draft permit requires the source to limit
material use to 5,600 gallons or less of cleaning solvent per year.
This is roughly equivalent to 25 tpy of VOCs. If a source locates in an
ozone nonattainment area, the draft permit requires the source to limit
material use to 1,300 gallons or less of cleaning solvent per year.
This is roughly equivalent to 7 tpy of VOC. Both annual material use
limits are based on a 12-month rolling total calculated each month. We
request comment on the use of these surrogate limits. In lieu of
establishing surrogate limits, we request comment on whether the final
permits should contain ton per year emission limitations and the use of
monitoring of material use as a compliance method. Finally, we request
comment on the appropriateness of establishing different limitations
based on the attainment status of the area and whether the specified
limitations should be slightly higher or slightly lower.
b. Should we establish additional requirements for serious, severe,
and/or extreme ozone nonattainment areas?
The draft permits contain additional requirements for sources that
locate in serious, severe, and extreme ozone nonattainment areas. These
requirements include requirements for changing paper or carbon
cartridge filters; wastewater evaporators; additional specifications
for closed-loop machines (e.g., proper exhausting and locking); leak
check and repair requirements; and enhanced recordkeeping and reporting
requirements. We adopted these practices from the South Coast Air
Quality Management District's rule for Dry Cleaners Using Solvent Other
Than Perchloroethylene \56\ for facilities located in ozone
nonattainment areas. We request comment on the need for these enhanced
requirements in serious, severe and/or extreme nonattainment areas.

VII. Description of the EPA's Proposed Permit by Rule Program in Indian
Country
A. What is a permit by rule?
For purposes of this proposal, a permit by rule is a standard set
of requirements that can apply to multiple sources with similar
emissions and other characteristics. This is similar to a general
permit. Unlike a general permit, however, we codify the permit by rule
requirements into regulation using a rulemaking process, rather than
establish the requirements through a general permit document that
undergoes notice and comment.
For purposes of this proposal, the permit by rule mechanism is a
permit streamlining approach that reduces the time permitting
authorities must devote to reviewing permit applications and issuing
permits for source categories or emissions generating activities that
pose a lower environmental concern. We believe that permits by rule
offer another cost-effective means of issuing permits, and provide a
quicker and simpler alternative mechanism for permitting true minor
sources than the site-specific permit or standard general permit
process.
State and local reviewing authorities use the permit by rule
mechanism to authorize construction of less complex sources, and
sources that emit at specified levels below the major stationary source
thresholds. The EPA has approved several state or local permits by rule
programs into SIPs.\57\ By this proposal, we would provide similar
opportunities for permitting efficiency in Indian country, while also
providing a comparable level of protection of air quality.
---------------------------------------------------------------------------
\57\ The EPA has approved the following permits by rule: (1)

---------------------------------------------------------------------------
B. How would a permit by rule program operate in Indian Country?
As proposed in this notice, once the EPA identifies a source
category or emissions generating activity for which the permit by rule
mechanism would offer permit streamlining benefits, while at the same
time protecting air quality, the EPA will codify a nationally
applicable permit by rule for those similar sources into a new section
of the Indian Country Minor NSR FIP. If the permit by rule will apply
only at a regional level, then the EPA regional reviewing authority
will conduct the rulemaking process, and appropriately limit the
applicability of the permit by rule to a specified geographic area.
As proposed, permits by rule would be used to address source
categories of true minor sources, where the reviewing authority does
not need to conduct an in-depth review to evaluate whether an
individual source meets requirements in the permit. A source category
would be covered by a permit by rule if the reviewing authority needs
to take no further action other than receiving confirmation from an
individual source that it meets all appropriate criteria to be eligible
for coverage under the permit by rule. Under a permit by rule, an
individual source would be subject to the operational, monitoring and
recordkeeping requirements specified in this rule.
In this action, we propose to amend the Indian Country Minor NSR
rule general permit provisions at 40 CFR 49.156 to set forth the unique
elements of the permits by rule process discussed below. We also
propose permits by rule for several specific source categories. The
proposed permits by rule program would follow a more streamlined
application process that would allow an individual applicant to notify
the reviewing authority that it meets the eligibility criteria for the
permit and the permit conditions. The applicant would need to complete
an application, but would keep it on file to be available upon request.
The source would simply need to send a notification letter signed by an
authorized official representing the source who certifies that the
source is eligible for the permit and is complying or will comply with
all of the permit's conditions. This streamlined application process
would serve as a ``notification'' and would streamline permitting for
eligible sources, and make it easier for the reviewing authority to
implement the permit by rule program compared to traditional site-
specific permits and standard general permits.
We request comment on this streamlined permit by rule approach.
Specifically, while it would streamline the permitting process for the
applicant, it would not allow the public the opportunity (as that
available under the general permit program) to object, except by
judicial challenge, to a particular source receiving coverage under a
specific permit by rule. We specifically request comment on whether
this tradeoff of allowing more streamlining while reducing the public's
ability to object to the granting of permit coverage in specific
instances represents sound policy and is appropriately protective of
air quality.
Like general permits, the EPA is proposing that true minor sources
may use the permit by rule mechanism to gain authorization to construct
or modify, and then operate a source. We are also proposing to allow
the use of the permits by rule mechanism to create synthetic minor
sources. We are proposing this approach to remain consistent with our
current policies on the use of general permits in Indian country. As
discussed in Section X, we propose to change this policy (and request
comment) to allow general permits to create synthetic minor sources
both to regulate construction, modification and then operation, and to
obtain minor source status. Similarly, we propose to allow reviewing
authorities to use the permit by rule mechanism for these same purposes
and
[[Page 2567]]
request comment on the proposed change.
Like general permits, a reviewing authority's receipt of a source
notification requesting coverage under a permit by rule qualifies as a
final action for purposes of judicial review (see 40 CFR 49.159). Any
such review is limited to the issue of whether a source meets the
eligibility requirements for coverage under the permit by rule. If a
reviewing authority accepts a source's notification of coverage under a
permit by rule, the source must post, prominently, a copy of the
written confirmation granting such request at the location of the
source. Also, like general permits, any source subject to a permit by
rule is subject to enforcement action for failure to obtain a permit to
construct and then operate if the source constructs the affected
emissions unit(s) under coverage of a permit by rule, and we later
determine that the source was not eligible for coverage under the
permit by rule.
C. Requirements of the ESA and NHPA
Similar to general permits, prior to seeking coverage under a
permit by rule, a source must satisfactorily address the permit
requirements related to the ESA and the NHPA. Attached to the
notification the source sends to the reviewing authority, the EPA
provides guidance to assist sources in complying with these
requirements. Section V.F. above describes the process for complying
with a permit by rule in more detail.
VIII. Proposed Permits by Rule
As an alternative to general permits, we are proposing to establish
permits by rule, for three source categories: GDFs, auto body repair
and miscellaneous surface coating operations, and petroleum dry
cleaning facilities. We are proposing these source categories for
permits by rule because they are the most straightforward, have the
least variation in pieces of equipment and the simplest compliance
requirements.
We are not providing specific regulatory language for any of the
proposed permits by rule but rather are proposing to codify the
requirements of the proposal general permits of the specified source
category. If we decide to finalize a permit by rule for any of the
three source categories, then we will codify the requirements as
contained in the proposed draft general permit for that source
category, with consideration of any changes that may be appropriate
after we review public comments on the general permits. In other words,
whether we use the permits by rule or the standard general permit
mechanism, we propose to apply identical requirements to regulate
construction and modification activities of affected emission units in
the specified source category. We believe that the proposed general
permits provide the public with a sufficient understanding of the
contents of any final rule, and, therefore, satisfy our obligations
under section 301(a) of the CAA.
The EPA welcomes comments on all aspects of the proposed general
permits and permits by rule approaches, mechanisms, and categories
covered by this proposed notice. In particular, we request that
commenters focus on the differences between notification procedures for
general permits and permits by rule. Commenters should inform the EPA
if the process laid out for permits by rule is appropriate. We request
comments on whether the permit by rule terms and conditions should be
identical to the general permits terms and conditions, or whether they
should differ.
IX. Implementation Documents and Tools
We are providing several tools and documents to assist sources with
obtaining coverage under the general permits and permits by rule for
the five source categories that are the subject of today's proposal.
The tools are drafted based on our preferred approach of general
permits. If we decide to issue permits by rule for one or more of the
three categories we are proposing in the alternative today, then we
will need to adjust the wording in the documents to reflect that tool
being made available for a permit by rule and not a general permit. The
background documents support both our general permit proposal (and
permit by rule proposal, in the alternative); therefore, those
documents cite both general permits and permits by rule as the permit
types they support.
The tools consist of the following six types of documents:
Request for Coverage: This form is for sources seeking to use
general permits and is essentially an application to request coverage
under a general permit. The application asks for contact and location
information, as well as more in-depth operational and source-specific
information. The application will also guide sources through processes
to comply with permit requirements related to the ESA and the NHPA.
The general permit applications for certain source categories in
today's proposal (i.e., auto body repair and miscellaneous surface
coating operations; GDFs; and petroleum dry cleaning facilities) are
more streamlined because sources in those categories represent more
straightforward operations, largely involve one air pollutant (i.e.,
VOCs) and, therefore, necessitate less intensive review for approval.
The general permit application forms for the three categories primarily
ask whether you have or will comply with relevant requirements. For
example, for the auto body repair and miscellaneous surface coating
operations permits, the general permit application asks questions
concerning whether you have or comply with certain requirements such as
throughput limits, but does not require details on affected units. By
contrast, the general permit applications for HMA and SQCS facilities
request more detailed technical information about the proposed facility
in question because these facilities are more complex and involve
multiple operations and pollutants.
For auto body repair and miscellaneous surface coating operations;
GDFs; and petroleum dry cleaning facilities, this form also serves as
an application for sources seeking coverage under a permit by rule
should the EPA decide to issue one or more for these categories. The
source would need to complete the shortened applications and keep a
record on file. Successfully completing the application will enable the
source to determine if it can certify to the reviewing that it meets
the permit's eligibility terms and conditions, which the source would
need to do via a letter in order to begin its construction or
modification.
Questionnaire: This tool is tailored to each source category and
guides sources through a series of questions to determine whether or
not it is eligible for coverage under a general permit. It is not
required to be completed or submitted. First, the source needs to
determine whether it is a true minor source and, therefore, subject to
the requirements of the minor NSR rule for Indian country. To do this,
a source needs to perform a PTE analysis (see PTE calculator below). If
the source determines that it is a true minor, the questionnaire asks
the source to consider a series of questions to determine if it
qualifies for the general permit or permit by rule. If the source does
not qualify for coverage, then it must seek a site-specific permit
under the minor source program (or a major source permit, if
appropriate).
Instructions: The document assists sources with information that
may be useful in completing the request for coverage application.
Permit Terms and Conditions: The permit is a specific document for
each
[[Page 2568]]
source category that lays out the general and specific terms and
conditions of the permit, including the specific emission limitations
and standards and monitoring, recordkeeping, reporting and notification
requirements.
PTE Calculator: This spreadsheet-based tool helps sources in
specific source categories calculate the PTE of its affected emissions
units, using data the source is expected to have on hand, such as
equipment specifications.
Background Document: These documents are provided as a reference
and contain important information:
Source category definition and characterization;
State minor source permit programs for that category used
for comparison;
Requirements for general permits and permits by rule for
that category; and
Threshold (emission limitations) development and rationale
for that category.

X. Reconsideration of the Use of General Permits To Create Synthetic
Minor Sources
On August 30, 2011, and November 4, 2011, the American Petroleum
Institute, the American Natural Gas Alliance and the Independent
Petroleum Association of America submitted a petition (and supplemental
petition) for reconsideration on the Indian Country Minor NSR rule to
the Administrator, under section 307(d)(7) of the CAA. Among other
issues, the petition asks the Administrator to reconsider our position
of not allowing reviewing authorities to issue general permits to
create synthetic minor sources.\58\

---------------------------------------------------------------------------
Section 49.158 of the Indian Country Minor NSR rule provides a
reviewing agency with the authority to issue synthetic minor permits.
Under the Indian Country Minor NSR rule, a synthetic minor permit
creates federally enforceable emission limitations that restrict a
source's ability to emit regulated NSR pollutants in an amount that
exceeds major source threshold(s). The Indian Country minor NSR
regulatory provisions, however, do not expressly address whether a
reviewing authority could use the general permit issuance process in 40
CFR 49.156 to satisfy the requirements for issuing synthetic minor
permits allowed by 40 CFR 49.158. Nonetheless, we received a comment on
the proposed rule requesting that we clarify that a reviewing authority
could issue general permits to create synthetic minor permits.
In response to this comment, we indicated that the final rule would
not allow a reviewing authority to use a general permit to create a
synthetic minor source, because we believed that the size and amount of
emissions from these sources warranted a case-by-case review of the
source and its proposed emission limitations.\59\ We did not, however,
add specific regulatory language to the final rule to restrict the use
of general permits in this manner.

---------------------------------------------------------------------------
The petitioners believe that a reviewing authority can establish
effective limits on PTE through general permits, and that there is no
need for case-by-case determinations for source types where equipment
and operations do not significantly vary from source to source (e.g.,
oil and gas facilities). The petitioners request that reviewing
authorities not preclude sources from obtaining synthetic minor
limitations through use of a general permit. In a letter to the
petitioners, dated December 19, 2012, the Administrator expressed her
intent to grant reconsideration of several aspects of the Indian
Country Minor NSR rule, including the use of general permits to create
synthetic minor sources.\60\

Country: Notice of Action Partially Granting Petition for
Reconsideration and Denying Request for Administrative Stay,'' U.S.

http://www.gpo.gov/fdsys/pkg/FR-2013-01-10/html/2012-31742.htm.
---------------------------------------------------------------------------
In this proposal, in response to the Administrator's decision to
grant reconsideration on this issue, we propose to allow a reviewing
authority to use general permits, including the permits by rule
mechanism, to create federally enforceable emission limitations that
can restrict operations of an otherwise major source, such that the
source qualifies as a synthetic minor source. The fact that a source's
PTE is above the major source threshold does not mean that standardized
permit conditions are necessarily inappropriate. Nor does it
necessarily mean that compliance determinations are more complex than
can be handled through a general permit. State and local permitting
agencies often successfully use these mechanisms to reduce permit
workload and to provide sources with regulatory certainty, and, a
number of streamlining and environmental benefits can result for
reviewing authorities, sources and the environment if we allow these
mechanisms. Accordingly, we believe we should reconsider our position
in light of the benefits of these approaches. While we continue to have
some concerns about the potential emissions impacts from sources that
otherwise would qualify as major sources, we believe that we can
address these concerns in the process of developing the synthetic minor
general permit or permit by rule for a given category.
While sources that would qualify as synthetic minor sources would
have the potential to emit pollutants above the major source thresholds
in the absence of enforceable restrictions, in many cases, the sources'
actual emissions remain well below these thresholds even without the
restrictions. This may arise, for example, when the source only
operates a limited number of shifts in a day, when the source operates
seasonally, or when the source sporadically uses a raw material with
higher emissions potential. Thus, these sources do not have, in actual
operation, the same potential for environmental impacts as facilities
operating at consistently higher emissions levels.
For example, we analyzed actual emissions from the 2008 National
Emissions Inventory (NEI) \61\ for HMA plants and SQCS facilities. In
that database, average emissions for several regulated NSR pollutants
for HMA plants are well below major source levels.\62\ This is
consistent with our understanding of how such facilities operate.
Typically, they operate seasonally and not each day of the year. The
average actual emissions for several regulated NSR pollutants for SQCS
facilities also were well below major source levels.\63\

Docket ID No. EPA-HQ-OAR-2011-0151 and online at http://www.epa.gov/air/tribal/tribalnsr.html.

PM2.5, NOX, SO2, CO and VOC. See

---------------------------------------------------------------------------
[[Page 2569]]
For sources that currently emit above major source threshold(s),
the availability of a pre-defined synthetic minor permit may provide
such facilities with a degree of regulatory certainty and create an
incentive to voluntarily reduce emissions to qualify for minor source
status. Such reductions in emissions benefit the environment and
provide another reason for us to reconsider our previous position on
this matter.
Moreover, irrespective of a source's emissions before qualifying
for a synthetic minor permit, that source must operate at levels below
the major source thresholds after qualifying for the permit, which is
also the case for true minor sources. If the synthetic minor permit
contains sufficient monitoring, recordkeeping and reporting provisions
to assure continuous compliance, then there may be little reason to
distinguish these sources for purposes of further regulation, because
their emissions potential is now essentially equivalent to that of a
true minor source. We request comment on this conclusion.
Finally, a synthetic minor permit being sought by a facility that
is also undergoing a modification that triggers NSR may provide the
public with more information and greater certainty as to the emissions
potential of the source. Absent the permit, for the part of the source
not being permitted as part of the modification, the source would be
under no obligation to report emissions on a continuous basis, and the
source could also, without a modification, increase emissions. A
synthetic minor permit would provide a limit on the total emissions the
facility would generate, and provide advance notice to the public of
the expected level of emissions from the facility. Synthetic minor
permitting also saves reviewing authority resources by potentially: (1)
Reducing the number of sources that need to obtain permits under the
title V and PSD/nonattainment NSR permitting programs; and (2) avoiding
a repetitive administrative process for each source that seeks a
synthetic minor permit with the same terms and conditions.
We request comment on all aspects of using general permits and
permits by rule to create synthetic minor sources generally and with
respect to the five source categories in this proposal. We request
specific comment on whether any regulatory changes in the permits being
proposed are necessary to implement this change in policy, given that
the current regulations do not expressly preclude the EPA from issuing
general permits to create synthetic minor sources. We also request
comment on whether, as a policy matter, the EPA should use general
permits and permits by rule to separate construction and modification
requirements from requirements for qualifying as a synthetic minor
source, even if the general permits/permits by rule would regulate the
same source category; or, whether the EPA can effectively achieve both
regulatory purposes in a single general permit/permit by rule. In
addition, we request comment on whether permits by rule as proposed in
this action are an appropriate type of permit for creating synthetic
minor sources, given that the permit notification does not provide an
opportunity for public input on the coverage of a particular source by
a permit by rule.
If the EPA allows otherwise major sources to qualify as synthetic
minor sources through use of general permits (or permits by rule), we
request comment on any specific changes we should make to the general
permits to include provisions for creating synthetic minor permits for
these source categories. For example, would the EPA need to require
more stringent monitoring, recordkeeping and reporting for synthetic
minor sources than currently contained in the draft general permits for
true minor sources? Should the EPA scale up the surrogate annual
allowable emission limitations to reflect a value closer to the major
source threshold, or should the EPA only issue synthetic minor permits
to sources with actual emissions at some margin below the major source
thresholds (e.g., 25-50 percent below the major source threshold)? If
the EPA includes synthetic minor limits in the final general permits,
these limits would be proportional to the limits currently contained in
the draft permit, as revised to reflect public comments.
We also request comment on whether, irrespective of our proposed
policy of not allowing a facility to qualify for more than one general
permit, which is discussed later in this document, we should,
nonetheless, allow a source to qualify to use a general permit or
permit by rule to become a synthetic minor source, and then
subsequently use a general permit or permit by rule to authorize
construction or modification activities. As stated in Section XI.B., we
are concerned that allowing a source to qualify for more than one
general permit or permit by rule may allow incremental increases in
emissions that could adversely impact air quality, or allow a source to
evade major source requirements. The use of multiple general permit
mechanisms for the purposes described here might not lead to
incremental emissions increases. Accordingly, we request comment on
allowing multiple general permits for these distinct purposes.
XI. Additional Areas Where Comment Is Being Sought
A. Should general permits and permits by rule be made available for
sources in the same source category?
The EPA requests comments on whether, for certain source
categories, the EPA should structure the permits so that eligible true
minor sources can receive coverage under permits by rule and synthetic
minor sources receive coverage under general permits. In addition, just
as we are proposing that general permits are more appropriate for more
complex source categories, we request comments on whether general
permits (and not permits by rule) are more appropriate for major
sources that seek to become ``synthetic'' minor sources. And, as we are
proposing that permits by rule are more appropriate for less complex
source categories, we request comments on whether permits by rule (and
not general permits) are more appropriate for true minor sources. We
request comment on whether this concept should be applied differently
or the same for different source categories.
For example, in some cases actual emissions for HMA plants and for
SQCS facilities for some regulated NSR pollutants may be above major
source levels. Perhaps these sources could be candidates for coverage
under synthetic minor general permits, while the smaller, true minor
sources could be candidates for coverage under permits by rule. We
request comments on this issue. In the docket, a background document is
provided for each of the categories in this proposal, which includes a
summary of NEI data for that category.
B. Can sources have more than one general permit or permit by rule at a
single location?
We request comment on whether we should allow a single stationary
source to gain coverage under more than one general permit and/or
permit by rule. In the questionnaires provided to assist applicants
with completing the applications and notifications of coverage, the EPA
asks applicants to provide PTE emissions for existing, new and modified
emission units to determine whether or not it qualifies for a true
minor source permit. The intent
[[Page 2570]]
is to ensure that a single stationary source does not gain coverage
under a general permit or permit by rule if its PTE emissions are above
major source levels. If multiple general permits or permits by rule are
an effective and efficient approach, what provisions are needed to
ensure sources do not become major and to ensure that the public has
adequate information about the source?
The need for multiple preconstruction permits could arise if the
stationary source proposes to modify equipment that could be regulated
by more than one general permit. For example, this could occur if a new
SQCS facility co-locates with a new HMA plant. This could also occur if
a source has some equipment covered by an existing general permit, and
then proposes to modify different equipment at a later date after we
have updated the general permit with new requirements. The source would
need to apply for coverage under and meet the requirements of the
updated permit for the proposed modification but would remain regulated
by the old general permit for the previous modifications. We are
concerned that if a single stationary source may construct or modify
through the use of multiple general permits, then that source may
inadvertently circumvent the major source NSR construction requirements
by failing to properly compute or track the stationary-source-wide PTE.
The EPA seeks comment on whether there are special recordkeeping
conditions that could be added to the general permits and/or permits by
rule to address this concern.
On the other hand, we also recognize that unless there are unique
air quality concerns, the site-specific permit terms and conditions for
each emission generating activity may not vary from those already in
the relevant general permits. As such, there may be little benefit from
engaging in a site-specific permitting action, other than to verify the
continued minor source eligibility of the stationary source. We request
comment on whether we should decline to issue more than one general
permit or permit by rule for stationary sources, or whether the
application/notification materials offer the EPA an adequate
opportunity to verify that source-wide PTE for a stationary source is
below major source levels.
XII. Additional Source Categories for Which the EPA Is Planning To
Propose General Permits and/or Permits by Rule
The EPA solicited input from tribal governments and the EPA
Regional Offices on which source categories should be covered by
streamlined permitting in Indian country. The tribes and the EPA
Regional Offices identified the source categories covered in this
proposal because they are thought to be common in Indian country and
good potential candidates for streamlined permitting. The input
included the following source categories that are also under
consideration for future action:
Printing operations (including solvent cleaning/
degreasing);
Engines (spark and compression ignition);
Concrete batch plants;
Saw mills;
Landfill operations;
Boilers; and
Oil and gas production and operations.
As a first step, we are requesting comment on whether these source
categories should receive coverage by general permits or permits by
rule, including comments as to what categories are appropriate for each
type of rule. We are not, however, proposing general permits or permits
by rule for these categories at this time. Rather, some or all of these
categories will be addressed in a subsequent action.
We have also consulted the best available (but incomplete) data we
have available to confirm the presence of these source categories in
Indian country. The number of sources in Indian country was determined
as part of the process to assess if general permits and/or permits by
rule are warranted for each sector. The NEI is the EPA's default
database on the location and type of emission sources in the U.S. The
NEI, however, is not complete with regards to sources in Indian
country. The EPA Regions 5 and 10 have also compiled lists of existing
sources in Indian country. We have culled the lists for Regions 5 and
10 and the NEI for the other eight regions (Regions 1 to 4 and 6 to 9)
to compile a source count by source type for sources located in Indian
country that fall into the categories listed above.\64\
---------------------------------------------------------------------------
\64\ The lists are available to consult at Docket ID No. EPA-HQ-
OAR-2011-0151 and online at http://www.epa.gov/air/tribal/tribalnsr.html.
---------------------------------------------------------------------------
With respect to landfill operations, the EPA specifically requests
comment on whether enough landfill activity is occurring in Indian
country to warrant the development of a general permit or permit by
rule. In connection with the EPA's Municipal Solid Waste Landfills New
Source Performance Standard (40 CFR 60.750, Subpart WWW), the EPA
created a database of active landfills across the U.S. from EPA's
Greenhouse Gas Reporting Program, Landfill Methane Outreach Program,
and Information Collection Request Center. The database indicates a
very small number of landfills in Indian country. These results were
compared to the source culling that we did with the NEI and the lists
of sources from Regions 5 and 10, which also showed few landfills in
Indian country. Based on this information, we are not convinced that
the resources necessary to develop a general permit and/or permit by
rule would be justified and welcome comment on the issue.\65\
---------------------------------------------------------------------------
\65\ The results of this analysis can be found in Docket ID No.
EPA-HQ-OAR-2011-0151 and online at http://www.epa.gov/air/tribal/tribalnsr.html.
---------------------------------------------------------------------------
For the remaining sectors under consideration for the use of a
general permit and/or permit by rule, we evaluated the number of
facilities by sector using the culled source lists. For all but two of
these other sectors, the results of our analysis found sufficient
facilities in each sector listed above to warrant the development of
general permits and/or permits by rule for these categories.\66\ Two
source categories--engines and oil and gas sources--did not appear in
significant numbers in the NEI because, as mentioned, it is an
incomplete data source in Indian country. However, discussions with
tribes have confirmed that both of these source types are prevalent
enough in Indian country to more than justify the resources necessary
to develop general permits. In addition, registrations of oil and gas
sources to the EPA's registration data base (required pursuant to the
Indian Country NSR rule) have been significant, further confirming the
presence of this source category in Indian country.
---------------------------------------------------------------------------

0151 and online at http://www.epa.gov/air/tribal/tribalnsr.html.
---------------------------------------------------------------------------
XIII. Rule Changes to the Indian Country Minor NSR Rule, Including
Extension of Deadline for the Indian Country Minor NSR Rule
We are proposing five changes to three separate provisions in the
existing Indian country minor NSR rule to ensure the smooth functioning
of the general permit program.
A. Amending Sec. 49.151(c)(1)(iii)(B)
The first provision we propose to amend is Sec.
49.151(c)(1)(iii)(B) addressing the timing for when a true minor source
must obtain a preconstruction permit. The provision currently requires
the owner/operator of a new true minor source, or an existing true
minor source undertaking a minor modification, to obtain a permit prior
to commencing construction by the earlier
[[Page 2571]]
of 6 months after the general permit for a source category is published
in the Federal Register or September 2, 2014.
We are proposing to amend this provision in two ways. First, we
propose to eliminate the requirement to obtain a permit beginning 6
months after the general permit for a source category is published in
the Federal Register if that date is before September 2, 2014. The
original intent of this provision was to ensure that sources in a
particular source category obtain preconstruction permits as soon as
practicable after we issue a general permit, rather than wait until
September 2, 2014. Because we currently do not anticipate that we will
complete the rulemakings to establish general permits to carry out the
minor NSR program in Indian country any earlier than 6 months prior to
September 2, 2014, we do not believe the clause is necessary. Moreover,
we received informal feedback that this clause is confusing. Therefore,
we propose to remove the clause to provide a clear date by which true
minor sources must obtain preconstruction permits. Except as explained
below, all true minor sources must obtain a preconstruction permit,
using the general permit mechanism or an alternative mechanism, before
constructing or modifying a true minor source on or after September 2,
2014.
Second, we propose to extend the permitting deadline for true minor
sources within the oil and gas source category by adding language to
provide an exception for true minor sources included in certain NAICS
codes related to the oil and gas operations and production source
category.\67\ For true minor sources within these NAICS codes, we
propose that sources must obtain a permit pursuant to Sec. Sec. 49.154
and 49.155 prior to commencing construction beginning on a fixed date
after September 2, 2014. We have begun work on a general permit for
true minor sources in the oil and gas production industry, which we
intend to discuss in a separate rulemaking action. We believe that an
extension of the permitting deadline for this industry is necessary
because of the additional time required to appropriately address issues
associated with this sector. We are requesting comment on extending the
September 2, 2014 deadline to a date within a range between September
2, 2015 to March 2, 2016.
---------------------------------------------------------------------------
\67\ 21111 oil and gas production/operations; 211111 Crude
petroleum and natural gas extraction; 211112 natural gas liquid
extraction; and 221210 Natural gas distribution.
---------------------------------------------------------------------------
B. Amending Sec. 49.156(e)
We propose to amend Sec. 49.156(e)(1) addressing the timing for
when a source that qualifies for a general permit may request coverage
under that permit. The provision currently specifies that a source
qualifying for a particular general permit may request coverage under
that general permit beginning 4 months after the effective date of the
general permit. We propose to remove this provision to make clear that
sources may seek coverage under a general permit as soon as it is
effective and need not wait an additional 4 months.
In addition, we propose to amend Sec. 49.156(e)(4) to shorten the
application review process for general permits from 90 to 45 days for
three source categories in today's proposal:
Auto body repair and miscellaneous surface coating
operations;
GDFs; and
Petroleum dry cleaning facilities.
Allowing this streamlining (combined with shorter applications for
these same three categories) will allow for reduced processing time for
general permits coverage requests for these categories and a reduction
in information required to be included in requests for coverage.
Specifically, a reviewing authority must either determine whether a
request for coverage is complete within 15-days from receiving a
source's request for coverage under the permit by rule or request any
additional information necessary to process the request. If a reviewing
authority requests additional information, an applicant must submit the
requested information within 15 days from the date of the reviewing
authority's request, or the reviewing authority may automatically deny
a source's request for coverage under the permit by rule. If the
reviewing authority receives all the requested information, then the
reviewing authority will grant or deny coverage under a permit by rule
no later than 45 days after the date the reviewing authority received
the request. We propose the shortened timeframe for a reviewing
authority's completeness review of a permit by rule, compared to
general permits, because the abbreviated and standardized request for
coverage \68\ process should allow the reviewing authority to readily
determine whether the source submitted all of the necessary
information.
---------------------------------------------------------------------------
\68\ 40 CFR 49.156 of the Indian Country NSR rule sets forth the
requirements for general permits, suggesting that the EPA may
develop standard application forms for general permits. In this
proposal, we have developed applications for general permits. We
have also developed the ``notification'' forms for permits by rule,
which satisfy all of the requirements applicants need to address but
do so in a more streamlined manner.
---------------------------------------------------------------------------
We propose to provide the reviewing authority the option of
automatically denying a source's request for coverage if the source
fails to submit any additional requested information within 15 days to
remain consistent with our intent to provide a streamlined notification
and review process. The streamlined nature of the general permits for
these three source categories is inconsistent with lengthy and
potentially open-ended ongoing exchanges with applicants to obtain
necessary information and not the best use of limited resources. If a
reviewing authority denies a request for coverage because a source
fails to submit requested information by the deadline, then the source
may re-apply at a later date to re-initiate the request for coverage.
C. Amending Sec. 49.160(c)(1)(ii) and (iii)
We propose to amend Sec. 49.160(c)(1)(ii) and (iii) that addresses
the timeframes for when true minor sources must register. The
provisions indicate that, if a true minor source commences construction
in the time period between the effective date of the rule and September
2, 2014, then the source must register with its reviewing authority
within 90 days after the source begins operation. If construction or
modification of a source commenced any time on or after September 2,
2014 and the source is subject to this rule, the source must report its
actual emissions (if available) as part of its permit application and
its permit application information will be used to fulfill the
registration requirements.
The EPA is proposing to amend these two provisions to reflect the
proposed extension for oil and gas sources discussed above in this
section. We are requesting comment on changing the September 2, 2014
deadline in these two paragraphs to a date within a range between
September 2, 2015 to March 2, 2016. For Sec. 49.160(c)(1)(ii), this
proposed change is necessary to ensure that oil and gas sources
continue to register past the September 2, 2014 date. For Sec.
49.160(c)(1)(iii), this proposed change is necessary to reflect that
the EPA is proposing to move the minor source permitting deadline for
oil and gas sources. If the EPA does take final action to do so, then
minor oil and gas sources will not be in a position to report their
actual emissions as part of a permit application and permit application
information because it will not be required at that point to obtain a
minor source permit. Hence, the need to propose to change the September
2,
[[Page 2572]]
2014 date to reflect the oil and gas minor source permitting deadline
extension.
XIV. Statutory and Executive Order Reviews
A. Executive Order 12866: Regulatory Planning and Review and Executive
Order 13563: Improving Regulation and Regulatory Review
This action is not a ``significant regulatory action'' under the
terms of EO 12866 (58 FR 51735, October 4, 1993) and is, therefore, not
subject to review under EOs 12866 and 13563 (76 FR 3821, January 21,
2011).
B. Paperwork Reduction Act
This action does not impose an information collection burden under
the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq.
Burden is defined at 5 CFR 1320.3(b). This action merely proposes to
establish general permits and/or permits by rule to satisfy the
requirements of the Minor NSR rule. Such permits are already available
in many states. It does not impose any new obligations or enforceable
duties on any state, local or tribal government or the private sector.
Therefore, this action does not impose an information collection
burden.
C. Regulatory Flexibility Act
The Regulatory Flexibility Act (RFA) generally requires an agency
to prepare a regulatory flexibility analysis of any rule subject to
notice and comment rulemaking requirements under the Administrative
Procedure Act or any other statute 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 businesses,
small organizations, and small governmental jurisdictions.
For purposes of assessing the impacts of today's rule on small
entities, small entity is defined as: (1) A small business as defined
by the Small Business Administration's (SBA) regulations at 13 CFR
121.201; (2) a small governmental jurisdiction that is a government of
a city, county, town, school district or special district with a
population of less than 50,000; and (3) a small organization that is
any not-for-profit enterprise which is independently owned and operated
and is not dominant in its field.
The EPA analyzed the impact of streamlined permitting on small
entities in the Review of New Sources and Modifications in Indian
Country (76 FR 38748, July 1, 2011). The EPA determined that that
action would not have a significant economic impact on a substantial
number of small entities. Today's action merely implements a particular
aspect of the Review of New Sources and Modifications in Indian
country. As such, this proposed action will not have a significant
economic impact on a substantial number of small entities.
D. Unfunded Mandates Reform Act
This action contains no federal mandates under the provisions of
Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), 2 U.S.C.
1531- 1538 for state, local, or tribal governments or the private
sector. This action imposes no enforceable duty on any state, local or
tribal government or the private sector. Therefore, this action is not
subject to the requirements of sections 202 and 205 of the UMRA. This
action is also not subject to the requirements of section 203 of UMRA
because it contains no regulatory requirements that might significantly
or uniquely affect small governments. This rule has no requirements
applicable to small governments and, as such, does not impose
obligations upon them.
E. Executive Order 13132: Federalism
This action does not have federalism implications. It will not have
substantial direct effects on the states, on the relationship between
the national government and the states, or on the distribution of power
and responsibilities among the various levels of government, as
specified in EO 13132. This action merely proposes to provide sources
in Indian country with streamlined permitting opportunities that are
generally available in states outside of Indian country. It does not
impose any new obligations or enforceable duties on any state, local or
tribal government or the private sector. Thus, EO 13132 does not apply
to this rule.
In the spirit of EO 13132, and consistent with the EPA policy to
promote communications between the EPA and state and local governments,
the EPA specifically solicits comment on this proposed action from
state and local officials.
F. Executive Order 13175: Consultation and Coordination With Indian
Tribal Governments
Pursuant to the EO 13175 (65 FR 67249, November 9, 2000), the EPA
may not issue a regulation that has tribal implications, that imposes
substantial direct compliance costs, and that is not required by
statute, unless the federal government provides the funds necessary to
pay the direct compliance costs incurred by tribal governments, or the
EPA consults with tribal officials early in the process of developing
the proposed regulation and develops a tribal summary impact statement.
The EPA has concluded that this action will not impose duties or
responsibilities on tribes, although it will have tribal implications.
The EPA has conducted outreach via on-going monthly meetings with
tribal environmental professionals in the development of this proposed
action. This proposal reflects priorities for developing permits,
comments on the general permits and suggestions for developing permits
by rules developed as a result of that outreach. The EPA will offer
consultation to elected tribal officials immediately after proposal to
provide an opportunity for meaningful and timely input into the
development of this regulation.
The EPA specifically solicits additional comment on this proposed
action from tribal officials.
G. Executive Order 13045: Protection of Children From Environmental
Health Risks and Safety Risks
The EPA interprets EO 13045 (62 FR 19885, April 23, 1997) as
applying only to those regulatory actions that concern health or safety
risks, such that the analysis required under section 5-501 of the EO
has the potential to influence the regulation. This action is not
subject to EO 13045 because it does not establish an environmental
standard intended to mitigate health or safety risks.
H. Executive Order 13211: Actions That Significantly Affect Energy
Supply, Distribution, or Use
This action is not subject to EO 13211 (66 FR 28355 (May 22,
2001)), because it is not a significant regulatory action under EO
12866.
I. National Technology Transfer and Advancement Act
Section 12(d) of the National Technology Transfer and Advancement
Act of 1995 (``NTTAA''), Public Law 104-113, 12(d) (15 U.S.C. 272 note)
directs the EPA to use voluntary consensus standards in its regulatory
activities unless to do so would be inconsistent with applicable law or
otherwise impractical. Voluntary consensus standards are technical
standards (e.g., materials specifications, test methods, sampling
procedures, and business practices) that are developed or adopted by
voluntary consensus standards bodies. The NTTAA directs the EPA to
provide Congress, through OMB, explanations when the agency decides not
to use available and
[[Page 2573]]
applicable voluntary consensus standards.
The proposed rulemaking involves technical standards. The EPA
proposes to use EPA Methods 5, 7E and 10. While the Agency identified
13 voluntary consensus standards (ASME B133.9-1994 (2001), ISO
9096:1992 (2003), ANSI/ASME PTC-38-1980 (1985), ASTM D3685/D3685M-98
(2005), CAN/CSA Z223.1-M1977, ANSI/ASME PTC 19-10-1981--Part 10, ISO
10396:1993 (2007), ISO 12039:2001, ASTM D5835-95 (2007), ASTM D6522-00
(2005), CAN/CSA Z223.2-M86 (1999), CAN/CSA Z223.21-M1978, ASTM D3162-94
(2005)) as being potentially applicable, we do not propose to use these
in this rulemaking. The use of these voluntary consensus standards
would not be practical with applicable law due to a lack of
equivalency, documentation, validation data and other important
technical and policy considerations.
The EPA welcomes comments on this aspect of the proposed rulemaking
and, specifically, invites the public to identify potentially-
applicable voluntary consensus standards and to explain why such
standards should be used in this regulation.
J. Executive Order 12898: Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations
EO 12898 (59 FR 7629 (Feb. 16, 1994)) establishes federal executive
policy on environmental justice. Its main provision directs federal
agencies, to the greatest extent practicable and permitted by law, to
make environmental justice part of their mission by identifying and
addressing, as appropriate, disproportionately high and adverse human
health or environmental effects of its programs, policies, and
activities on minorities and low-income populations in the United
States.
The EPA has determined that this proposed rule will not have
disproportionately high and adverse human health or environmental
effects on minority or low-income populations because it does not
affect the level of protection provided to human health or the
environment. This proposed rule merely implements certain aspects of
the Review of New Sources and Modifications in Indian Country. As such,
this proposed action will not have a disproportionately high and
adverse human health or environmental effects on minorities and low-

Our primary goal in developing this program is to ensure that air
resources in Indian country will be protected in the manner intended by
the CAA. As such, this rule will reduce adverse impacts by improving
air quality in Indian country. In addition, we seek to establish a
flexible preconstruction permitting program for minor sources in Indian
country that is comparable to similar programs in neighboring states in
order to create a more level regulatory playing field for owners and
operators within and outside of Indian country. This rule will reduce
an existing disparity by filling the regulatory gap.
