Air Quality Designations for the 2012 Primary Annual Fine
Particle (PM2.5) National Ambient Air Quality Standards
(NAAQS)

AGENCY: Environmental Protection Agency.

ACTION: Final rule.

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

SUMMARY: This rule establishes air quality designations for most areas
in the United States (U.S.), including areas of Indian country, for the
2012 primary annual fine particle (PM2.5) National Ambient
Air Quality Standards (NAAQS). Through these designations, the
Environmental Protection Agency (EPA) is identifying as
``nonattainment'' those areas that are violating the 2012
PM2.5 NAAQS based on quality-assured, certified air quality
monitoring data from 2011 to 2013 or those areas that are contributing
to a violation of the NAAQS in a nearby area. The EPA is initially
classifying all nonattainment areas as Moderate. Also, through this
final rule, the EPA is designating several areas as ``unclassifiable''
where the EPA cannot determine based on available information whether
the area is meeting or not meeting the NAAQS or where the EPA has not
determined whether the area contributes to a nearby violation.
Additionally, the EPA is deferring initial area designations for
several areas where the EPA cannot determine using available data
whether the areas are meeting or are not meeting the NAAQS, but for
which forthcoming data will likely result in complete and valid data
needed to determine a designation. The EPA will assess these data as
they become available and promulgate initial area designations for the
deferred areas through a separate rulemaking action. The EPA is
designating as ``unclassifiable/attainment'' all remaining areas of the
country.

DATES: The effective date of this rule is April 15, 2015.

I. Background

    On December 14, 2012, the EPA promulgated a revised primary annual
PM2.5 NAAQS to provide increased protection of public health
and welfare from fine particle pollution (78 FR 3086; January 15,
2013). In that action, the EPA revised the primary annual
PM2.5 standard, strengthening it from 15.0 micrograms per
cubic meter ([mu]g/m\3\) to 12.0 [mu]g/m\3\, which is attained when the
3-year average of the annual arithmetic means does not exceed 12.0
[mu]g/m\3\.
    Section 107(d) of the Clean Air Act (CAA), 42 U.S.C. 7407(d),
governs the process for initial area designations after the EPA
establishes a new or revised NAAQS. Under section 107(d), each governor
is required to, and each tribal leader may, if they so choose,
recommend air quality designations, including the appropriate
boundaries for nonattainment areas, to the EPA by a date which cannot
be later than 1 year after the promulgation of a new or revised NAAQS.
The EPA considers these recommendations as part of its duty to
promulgate the formal area designations and boundaries for the new or
revised NAAQS. If, after careful consideration of these
recommendations, public input received and the EPA's own technical
analyses, the EPA believes that it is necessary to modify a state's
recommendation and to promulgate a designation different from a state's
recommendation, then the EPA must notify the state at least 120 days
prior to promulgating the final designation and the EPA must provide
the state an opportunity to demonstrate why any proposed modification
is inappropriate. These modifications may relate either to the
designation of an area or to the boundaries of an area.

II. Purpose

    The purpose of this action is to announce and promulgate initial
area designations for most areas of the country with respect to the
2012 annual PM2.5 NAAQS in accordance with the requirements
of CAA section 107(d). The EPA is designating areas as nonattainment,
unclassifiable, or unclassifiable/attainment. In addition, the EPA is
initially classifying all nonattainment areas as Moderate pursuant to
the particulate matter-specific provisions of subpart 4 of Part D of
Title I of the CAA. The tables at the end of this final rule
(amendments to 40 CFR 81.301-356) list all areas that the EPA is
designating in each state and in areas of Indian country.
    In this action, the EPA is designating 14 areas in six states,
including two multi-state areas, as nonattainment for the 2012
PM2.5 NAAQS. The EPA is designating three areas, including
the entire state of Illinois, as unclassifiable because these areas
have ambient air quality monitoring sites that lack complete data for
the relevant period from 2011-2013. Therefore, the EPA cannot
determine, based on available information, whether or not these areas
are meeting or not meeting the NAAQS, and also has not determined
whether these areas contribute to a nearby violation.
    The EPA is deferring initial area designations for ten areas where
available data, including air quality monitoring data, are insufficient
to determine whether the areas are meeting or are not meeting the
NAAQS. For these areas, the EPA believes that additional air quality
monitoring data will result in complete and valid data sufficient to
inform a designation determination. Accordingly, the EPA is deferring
designations for these areas and using the additional time available as
provided under section 107(d)(1)(B) of the CAA to assess relevant
information and subsequently promulgate initial designations for the
identified areas through a separate rulemaking action or actions. The
ten deferred areas include eight areas in the state of Georgia,
including two neighboring counties in the bordering states of Alabama
and South Carolina, the entire state of Tennessee, excluding three
counties in the Chattanooga area, and the entire state of Florida. The
EPA is designating all the remaining state areas and areas of Indian
country as unclassifiable/attainment.
    Consistent with the EPA's ``Policy for Establishing Separate Air
Quality Designations for Areas of Indian Country'' (December 20, 2011),
the EPA is designating one area of Indian country separately from its
adjacent/surrounding state areas.\1\ The lands of the Pechanga Band of
Luise[ntilde]o Mission Indians in Southern California are being
designated as a separate unclassifiable/attainment area.

III. What is PM2.5 and how is it formed?

    Ambient, or outdoor, air can contain a variety of pollutants,
including particulate matter (PM). Airborne PM can be comprised of
either solid or liquid particles, and can be a complex mixture of
particles in both solid and liquid form. The most common constituents
of airborne PM include sulfate (SO4); nitrate
(NO3); ammonium; elemental carbon; organic mass; and
inorganic material, generally referred to as ``crustal'' material,
which can include metals, dust, sea salt and other trace

elements. Airborne PM can be of different sizes, commonly referred to
as ``coarse'' or ``fine'' particles. Fine particles, in general terms,
are particulate matter with an aerodynamic diameter less than or equal
to a nominal 2.5 micrometers ([mu]m) in diameter. For this reason,
particles of this size are referred to as PM2.5.
PM2.5 commonly includes ``primary'' particles and
``secondary'' particles. Primary particles, or direct PM2.5,
are emitted directly into the air as solid or liquid particles by a
variety of sources (e.g., elemental carbon from diesel engines or
wildfires, or condensable organic particles from gasoline engines).
Secondary particles are formed in the atmosphere as a result of
reactions between specific pollutants known as PM2.5
precursors (e.g., SO4 and NO3 from emissions of
mobile and stationary sources of oxides of nitrogen and sulfur dioxide
combined with ammonia).

IV. What are the health and welfare concerns that the 2012
PM2.5 NAAQS address?

    The human health effects associated with long- or short-term
exposure to PM2.5 are significant and include premature
mortality, aggravation of respiratory and cardiovascular disease (as
indicated by increased hospital admissions and emergency room visits)
and development of chronic respiratory disease. In addition, welfare
effects associated with elevated PM2.5 levels include
visibility impairment as well as effects on sensitive ecosystems,
materials damage and soiling, and climatic and radiative processes.\2\
---------------------------------------------------------------------------

    \2\ For a complete discussion of the human health and welfare
effects associated with exposure to elevated concentrations of
particulate matter, see generally ``Integrated Science Assessment
for Particulate Matter.'' U.S. Environmental Protection Agency,
Office of Research and Development, National Center for
Environmental Assessment-RTP Division, February 10, 2010. EPA/600/R-
08/139F. Available at: http://www.epa.gov/ncea/pdfs/partmatt/Dec2009/PM_ISA_full.pdf. See Chapter 2.
---------------------------------------------------------------------------

    The revised 2012 primary annual PM2.5 standard will
provide increased protection for children, older adults, persons with
pre-existing heart and lung disease, and other at-risk populations
against an array of PM2.5-related adverse health effects.

V. What are the CAA requirements for air quality designations and what
action has the EPA taken to meet these requirements?

    When the EPA promulgates a new or revised NAAQS, the EPA is
required to designate areas as nonattainment, attainment, or
unclassifiable, pursuant to section 107(d)(1) of the CAA. The CAA
requires the EPA to complete the initial area designation process
within 2 years of promulgating the NAAQS. However, if the Administrator
has insufficient information to make these designations within that
time frame, the EPA has the authority to extend the deadline for
designation decisions by up to 1 additional year.
    The initial area designations process is one of the first steps in
the state and federal partnership to implement the NAAQS and improve
air quality. By no later than 1 year after the promulgation of a new or
revised NAAQS, each state governor is required to recommend air quality
designations, including the appropriate boundaries for areas, to the
EPA. The EPA reviews those state recommendations and accepts them
unless the Administrator deems that a modification is necessary. The
statute does not define the term ``necessary,'' but the EPA interprets
this section of the CAA to authorize the Administrator to modify
designations that do not meet the statutory requirements or are
otherwise inconsistent with the facts or analysis deemed appropriate by
the EPA. If the EPA is considering modifications to a state's initial
recommendation, the EPA is required to notify the state of any such
intended modifications to its recommendation not less than 120 days
prior to the EPA's promulgation of the final designation. These
notifications are commonly known as the ``120-day letters.'' If the
state does not agree with the EPA's intended modification(s), it then
has an opportunity to respond to the EPA to demonstrate why it believes
the modification(s) is (are) inappropriate. In the event that a state
fails to provide any recommendation for an area, in whole or in part,
the EPA is still required to promulgate a designation that the
Administrator deems appropriate, pursuant to section 107(d)(1)(B)(ii).
    Section 107(d)(1)(A)(i) of the CAA defines a nonattainment area as
``any area that does not meet (or that contributes to ambient air
quality in a nearby area that does not meet) the national primary or
secondary ambient air quality standard for the pollutant.'' If an area
meets either prong of this definition, then the EPA is obligated to
designate the area as ``nonattainment.'' The EPA believes that section
107(d) provides the agency with discretion to determine how best to
interpret the terms in the definition of a nonattainment area (e.g.,
``contributes to'' and ``nearby'') for a new or revised NAAQS, given
considerations such as the nature of a specific pollutant, the types of
sources that may contribute to violations, the form of the standards
for the pollutant, and other relevant information. In particular, the
EPA believes that the statute does not require the agency to establish
bright line tests or thresholds for what constitutes ``contribution''
or ``nearby'' for purposes of designations.\3\ Similarly, the EPA
believes that the statute permits the EPA to evaluate the appropriate
application of the term ``area'' as may be appropriate for a particular
NAAQS. The EPA believes that the statute permits the EPA to evaluate
the appropriate application of the term ``area'' to include geographic
areas based upon full or partial county boundaries, and contiguous or
non-contiguous areas, as may be appropriate for a particular NAAQS. For
example, section 107(d)(1)(B)(ii) explicitly provides that the EPA can
make modifications to designation recommendations for an area ``or
portions thereof,'' and under section 107(d)(1)(B)(iv) a designation
remains in effect for an area ``or portion thereof'' until the EPA
redesignates it.
---------------------------------------------------------------------------

    \3\ This view was confirmed in Catawba County v. EPA, 571 F.3d
20 (D.C. Cir. 2009).
---------------------------------------------------------------------------

    Section 107(d)(1)(A)(iii) provides that any area that the EPA
cannot designate on the basis of available information as meeting or
not meeting the standards should be designated as ``unclassifiable.''
Historically for PM2.5, the EPA designates the remaining
areas as ``unclassifiable/attainment'' indicating that the areas either
have attaining air quality monitoring data or that air quality
information is not available because the areas are not monitored, and
the EPA has not determined that the areas contribute to a violation in
a nearby area.
    Section 301(d) of the CAA authorizes the EPA to approve eligible,
federally-recognized tribal governments to implement provisions of the
CAA. Pursuant to section 301(d)(2), the EPA promulgated regulations,
known as the Tribal Authority Rule (TAR), on February 12, 1999. 63 FR
7254, codified at 40 CFR part 49. That rule specifies those provisions
of the CAA for which it is appropriate to treat tribes in a similar
manner as states. Under the TAR, tribes may choose to develop and
implement their own CAA programs, but are not required to do so. The
TAR also establishes procedures and criteria by which tribes may
request from the EPA a determination of eligibility for such treatment.
The designations process contained in section 107(d) of the CAA is
included among those provisions determined to be appropriate by the EPA
for treatment of tribes in the same manner as states. Under the TAR,
tribes generally are not subject to the same submission schedules
imposed by

the CAA on states. As authorized by the TAR, tribes may seek
eligibility to submit designation recommendations to the EPA. In
addition, CAA section 301(d)(4) gives the EPA discretionary authority,
in cases where it determines that treatment of tribes as identical to
states is ``inappropriate or administratively infeasible,'' to provide
for direct administration by regulation to achieve the appropriate
purpose.
    Seven tribes are currently eligible to submit their own
recommendations under section 107(d). Nonetheless, the EPA invited all
tribes to submit recommendations and supporting documentation
concerning designations for the 2012 annual PM2.5 NAAQS.
Tribes could also comment on state recommendations and the EPA
modifications. The EPA worked with all tribes that requested an
opportunity to submit designation recommendations.
    On April 16, 2013, the EPA issued a guidance memorandum to EPA
Regional Administrators that provided information on the schedule and
process for initially designating areas for the purpose of implementing
the 2012 annual PM2.5 NAAQS.\4\ The Regional Offices were
asked to share the memorandum with their state and tribal agencies.
Within the memorandum, the EPA specified that consistent with the
schedule in section 107(d)(1) of the CAA, as stated in the
PM2.5 NAAQS final rule, state governors were required to
submit, and tribes can choose to submit, their initial designation
recommendations to the EPA no later than 1 year following promulgation
of the revised NAAQS, or by December 13, 2013. The memorandum
identified that the EPA would use the most recent air quality
monitoring data and evaluate the following five factors in making final
nonattainment area boundary decisions for the revised annual
PM2.5 NAAQS: Air quality data, emissions and emissions-
related data, meteorology, geography/topography, and jurisdictional
boundaries.
---------------------------------------------------------------------------

    \4\ Memorandum dated April 16, 2013, from Gina McCarthy,
Assistant Administrator, US EPA, to Regional Administrators, Regions
1-10, titled, ``Initial Area Designations for the 2012 Revised
Primary Annual Fine Particle National Ambient Air Quality
Standard.'' Available at http://www.epa.gov/pmdesignations/2012standards/docs/april2013guidance.pdf.
---------------------------------------------------------------------------

    Most states and several tribes submitted designation
recommendations and supporting documentation to the EPA by December 13,
2013. On August 19, 2014, the EPA sent letters to governors and tribal
leaders notifying them of the EPA's preliminary response to their
designation recommendations for the 2012 primary annual
PM2.5 NAAQS.\5\ These letters, commonly referred to as the
``120-day letters,'' conveyed the EPA's intended designations based on
an evaluation of complete, certified, and quality-assured monitored air
quality data for 2011-2013, including an evaluation of exceptional
event claims. The letters also asked states to submit any additional
information that they wanted the EPA to consider in its final
designation decisions by October 29, 2014.
---------------------------------------------------------------------------

    \5\ If the EPA believes it is necessary to make any
modifications to a state's or tribe's initial recommendations,
including area boundaries, then the EPA is required to notify the
state or tribe of this fact by letter no later than 120 days prior
to finalizing the designation.
---------------------------------------------------------------------------

    Although not required by section 107(d) of the CAA, the EPA also
provided an opportunity for members of the public to comment on the
EPA's August 2014 response letters to states and tribes. The EPA
announced a 30-day public comment period in the Federal Register on
August 29, 2014 (79 FR 51517). In this announcement, the EPA requested
that interested parties submit their comments to the regulatory docket
on or before September 29, 2014. The EPA received several requests from
stakeholders for additional time to prepare their comments. Some of the
requesters noted that the 30-day comment period being offered by the
EPA was insufficient time to review the EPA's responses to states' and
tribes' recommended designations and to compile meaningful responses
due to the complexity of the issues impacting certain areas. Due to the
EPA's statutory obligation to finalize the initial area designations in
December 2014, the EPA did not extend the public comment period. State
and tribal initial recommendations and the EPA's responses, including
modifications, were posted on a publically accessible Web site (http://www.epa.gov/pmdesignations/2012standards/regs.htm). Timely comments
from the public and the EPA's responses to significant comments are in
the docket for this action.
    State areas designated as nonattainment are subject to planning and
emission reduction requirements as specified in the CAA. As noted
previously, the EPA is classifying all nonattainment areas as Moderate,
which is the initial nonattainment area classification for all areas
pursuant to CAA section 188.\6\ In accordance with CAA section 188(c),
the attainment date for each Moderate area shall be as expeditiously as
practicable, but no later than the end of the sixth calendar year after
the designation. Within the next several months, the EPA intends to
propose an implementation rule to assist states in the development of
state implementation plans for attaining the PM2.5
standards.
---------------------------------------------------------------------------

    \6\ See Natural Resources Defense Council and Sierra Club v.
EPA, No. 08-1250 (D.C. Cir. January 4, 2013), indicating that the
provisions in subpart 4 (sections 188-190) apply to implementation
of PM2.5 NAAQS.
---------------------------------------------------------------------------

VI. What air quality data is the EPA using for these designations?

    The final PM2.5 designation decisions announced in this
action are based on air quality monitoring data for calendar years
2011--2013, including an evaluation of exceptional event claims.\7\
During the designations process, several states commented that the
agency should delay designations to consider additional air quality
data from 2014 in the designations decisions. As discussed earlier, the
EPA must by law make final designation decisions within 2 years of
promulgating a new or revised NAAQS, or in December 2014 based on the
December 2012 promulgation of the revised annual PM2.5
NAAQS, unless the EPA lacks sufficient information. This statutory
deadline and the practical difficulties of obtaining complete, quality-
assured, certified PM2.5 data for the entirety of calendar
year 2014 in December 2014 preclude the EPA from using 2014 data for
this action. Under normal circumstances, such data would not be
available for some time following the end of the calendar year, and,
under the applicable regulations, states would not be required to
certify such data until May 1, 2015. However, because designations are
being promulgated near the end of calendar year 2014, and, because
complete, quality-assured, certified 2014 data may become available for
some areas quickly, the EPA is providing a process by which a full year
of 2014 data that becomes available early in 2015 could be used in the
designation process. We have provided that the final PM2.5
designation decisions announced in this action will be effective on the
date 90 days following the date of publication of this action in the
Federal Register. If any state submits complete, quality-assured,
certified 2014 data to the EPA by February 27, 2015, that suggest that
a change of designation status is appropriate for any area within that
state, and the EPA agrees that a change of designation status is
appropriate, then we will withdraw the designation announced in this
action for such area and issue another designation that

reflects the inclusion of 2014 data. We emphasize that we will conduct
this process only for those states that submit the necessary complete,
quality-assured, certified data by the deadline and in those instances
where we can complete the analysis and effect the change of designation
status before the original effective date established by this final
action.
---------------------------------------------------------------------------

    \7\ Exceptional event claims influenced the EPA's designation
decisions for areas in the state of Hawaii and for Lemhi County,
Idaho.
---------------------------------------------------------------------------

    If inclusion of 2014 data submitted by a state or tribal air agency
causes an area to change from nonattainment to attainment, the EPA will
change the designation for the area where it is neither monitoring a
violation of the standards nor contributing to a violation of the
standards in another nearby area. If inclusion of 2014 data submitted
by a state or tribal air agency results in nonattainment in an area
that was designated attainment, we will evaluate the reasons for the
violation in the area and determine the appropriate course of action,
which could include actions to change the designation to nonattainment
for the area and any nearby areas that contribute to the violation.
Also, the EPA commits to evaluate 2014 data for deferred areas when it
receives complete, quality-assured, certified data from the state,
which is due no later than May 1, 2015. At that time, the EPA will
evaluate appropriate designations for such affected areas.

VII. How do designations affect areas of Indian country?

    Following the EPA Policy on Consultation and Coordination with
Indian Tribes, the EPA offered consultation to tribal officials early
in the initial area designations process to permit them to have
meaningful and timely input. The EPA subsequently consulted with all
tribes who requested consultation.
    In this document, all areas of Indian country are being designated
as part of their surrounding state areas, with the exception of areas
of Indian country for the Pechanga Band of Luise[ntilde]o Mission
Indians, which is being designated as a separate unclassifiable/
attainment area, consistent with the EPA's Tribal Designations
Policy.\8\
---------------------------------------------------------------------------

    \8\ See http://www.epa.gov/ozonedesignations/2008standards/documents/20120117indiancountry.pdf for ``Policy for Establishing
Separate Air Quality Designations for Areas of Indian Country''
(December 20, 2011).
---------------------------------------------------------------------------

VIII. Where can I find information forming the basis for this rule and
exchanges between the EPA, states and tribes related to this rule?

    Information providing the basis for this action are provided in
several technical support documents (TSDs), a response to comments
document (RTC) and other information in the docket. The TSDs, RTC, the
EPA's guidance memorandum, copies of correspondence regarding this
designations process between the EPA and the states, tribes and other
parties, are available for review at the EPA Docket Center listed above
in the ADDRESSES section of this document and on the agency's
PM2.5 Designations Web site at http://www.epa.gov/pmdesignations/2012standards/regs.htm. State-specific and area-specific
information is available from the EPA Regional Offices.

IX. Environmental Justice Considerations

    The CAA requires that the EPA designate as nonattainment ``any area
that does not meet (or that contributes to ambient air quality in a
nearby area that does not meet) the national primary or secondary
ambient air quality standard for the pollutant.'' By designating as
nonattainment areas where available information indicates a violation
of the 2012 annual PM2.5 NAAQS or a contribution to a nearby
violation, this action protects all those residing, working, attending
school, or otherwise present in those areas regardless of minority or
economic status.

X. 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 exempt from review by the Office of Management and
Budget because it will respond to the CAA requirement to promulgate air
quality designations after promulgation of a new or revised NAAQS.

B. Paperwork Reduction Act (PRA)

    This action does not impose an information collection burden under
the PRA. This action fulfills the non-discretionary duty for the EPA to
promulgate air quality designations after promulgation of a new or
revised NAAQS, and does not contain any information collection
activities.

C. Regulatory Flexibility Act (RFA)

    This action is not subject to the RFA. The RFA applies only to
rules subject to notice and comment rulemaking requirements under the
Administrative Procedure Act (APA), 5 U.S.C. 553, or any other statute.
This rule is not subject to the APA but is subject to CAA section
107(d)(2)(B), which does not require notice and comment rulemaking to
take this action.

D. Unfunded Mandates Reform Act (UMRA)

    This action does not contain any unfunded mandate as described in
UMRA, 2 U.S.C. 1531-1538, and does not significantly or uniquely affect
small governments. The action implements mandates specifically and
explicitly set forth in the CAA and fine particulate matter NAAQS (40
CFR 50.18). The CAA establishes the process whereby states take primary
responsibility in developing plans to meet the PM2.5 NAAQS.

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.

F. Executive Order 13175: Consultation and Coordination With Indian
Tribal Governments

    This action has tribal implications. However, it will neither
impose substantial direct compliance costs on federally recognized
tribal governments, nor preempt tribal law. Areas of Indian country are
being designated as part of this action.
    The EPA offered consultation to tribal officials under the EPA
Policy on Consultation and Coordination with Indian Tribes early in the
process of developing this regulation to permit them to have meaningful
and timely input into its development. During the designations process,
the EPA consulted with all tribes who requested consultation. A summary
of that consultation is provided in the docket supporting this
rulemaking.

G. Executive Order 13045: Protection of Children From Environmental
Health and Safety Risks

    The EPA interprets Executive Order 13045 as applying to those
regulatory actions that concern environmental health or safety risks
that the EPA has reason to believe may disproportionately affect
children, per the definition of ``covered regulatory action'' in
section 2-202 of the Executive Order. This action is not subject to
Executive Order 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 Executive Order 13211, because it is
not a significant regulatory action under Executive Order 12866.

I. National Technology Transfer and Advancement Act (NTTAA)

    This rulemaking does not involve technical standards.

J. Executive Order 12898: Federal Actions to Address Environmental
Justice in Minority Populations and Low-Income Populations

    The EPA believes the human health or environmental risk addressed
by this action will not have potential disproportionately high and
adverse human health or environmental effects on any population,
including any minority, low-income or indigenous populations because it
does not affect the level of protection provided to human health or the
environment. The results of this evaluation of environmental justice
considerations is contained in section X of this preamble titled,
``Environmental Justice Considerations''.

K. Congressional Review Act (CRA)

    This action is subject to the CRA, and the EPA will submit a rule
report to each House of the Congress and to the Comptroller General of
the United States. This action is not a ``major rule'' as defined by 5
U.S.C. 804(2).

L. Judicial Review

    Section 307(b)(1) of the CAA indicates which Federal Courts of
Appeal have venue for petitions of review of final actions by the EPA.
This section provides, in part, that petitions for review must be filed
in the Court of Appeals for the District of Columbia Circuit: (i) When
the agency action consists of ``nationally applicable regulations
promulgated, or final actions taken, by the Administrator,'' or (ii)
when such action is locally or regionally applicable, if ``such action
is based on a determination of nationwide scope or effect and if in
taking such action the Administrator finds and publishes that such
action is based on such a determination.''
    This final action designating areas for the 2012 annual
PM2.5 NAAQS is ``nationally applicable'' within the meaning
of section 307(b)(1). This final action establishes designations for
areas across the U.S. for the 2012 annual PM2.5 NAAQS. At
the core of this final action is the EPA's interpretations of the
definitions of nonattainment, attainment, and unclassifiable under
section 107(d)(1) of the CAA, and its application of those
interpretations to areas across the country. For the same reasons, the
Administrator is also determining that the final designations are of
nationwide scope and effect for the purposes of section 307(b)(1). This
is particularly appropriate because, in the report on the 1977
Amendments that revised section 307(b)(1) of the CAA, Congress noted
that the Administrator's determination that an action is of
``nationwide scope or effect'' would be appropriate for any action that
has a scope or effect beyond a single judicial circuit. H.R. Rep. No.
95-294 at 323, 324, reprinted in 1977 U.S.C.C.A.N. 1402-03. Here, the
scope and effect of this final action extends to numerous judicial
circuits since the designations apply to areas across the country. In
these circumstances, section 307(b)(1) and its legislative history
calls for the Administrator to find the action to be of ``nationwide
scope or effect'' and for venue to be in the D.C. Circuit.
    Thus, any petitions for review of final designations must be filed
in the Court of Appeals for the District of Columbia Circuit within 60
days from the date final action is published in the Federal Register.
