Air Quality Designations for the 2010 Primary Nitrogen Dioxide 
(NO2) National Ambient Air Quality Standards

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: This rule establishes air quality designations for all areas 
in the United States for the 2010 Primary Nitrogen Dioxide 
(NO2) National Ambient Air Quality Standards (NAAQS). Based 
on air quality monitoring data, the EPA is issuing this rule to 
designate all areas of the country as ``unclassifiable/attainment'' for 
the 2010 NO2 NAAQS. The EPA is designating areas as 
``unclassifiable/attainment'' to mean that available information does 
not indicate that the air quality in these areas exceeds the 2010 
NO2 NAAQS.

DATES: The effective date of this rule is February 29, 2012.

ADDRESSES: The EPA has established a docket for this action under 
Docket ID No. EPA-HQ-OAR-2011-0572. All documents in the docket are

II. What is the purpose of this action?

    The purpose of this action is to promulgate and announce initial 
area designations for all areas of the country for the 2010 
NO2 NAAQS based on available information, in accordance with 
the requirements of the Clean Air Act (CAA). The list of all areas 
being designated in each state, and the boundaries of each area, appear 
in the tables at the end of this final rule. The EPA has been working 
closely with the states involved in these designations and several 
steps have been taken to announce that this rule is available. The EPA 
has posted the notice on several EPA Web sites.
    This notice identifies all areas of the United States (U.S.) as 
being designated as ``unclassifiable/attainment'' for the 2010 
NO2 NAAQS. The basis for designating these areas as 
``unclassifiable/attainment'' is monitored air quality data from 
calendar years 2008-2010 indicating no violations of the NAAQS.
    The EPA and state agencies are currently working to establish an 
expanded network of NO2 monitors, expected to be deployed in 
2013. Once 3 years of air quality data have been collected from the 
expanded network, the EPA will be able to evaluate NO2 air 
quality in additional locations.

III. What is nitrogen dioxide?

    NO2 is a reddish-brown, highly reactive gas that is 
formed in the ambient air through the oxidation of nitric oxide (NO). 
Nitrogen oxides (NOX) is the term used to describe the sum 
of NO, NO2, and other oxides of nitrogen. A variety of 
NOX compounds and their transformation products occur both 
naturally and as a result of human activities. Anthropogenic (i.e., 
manmade) emissions of NOX account for a large majority of 
all nitrogen inputs to the environment. The major sources of 
anthropogenic NOX emissions are high-temperature combustion 
processes, such as those occurring in automobiles and power plants. 
Most NOX from combustion sources (about 95 percent) are 
emitted as NO, which is readily converted to NO2 in the 
environment; the remainder is emitted largely as NO2. 
Natural sources of NOX are lightning, biological and 
abiological processes in soil, and stratospheric intrusion.

IV. What are the health concerns addressed by the NO2 
standards?

    Current scientific evidence links short-term NO2 
exposures, ranging from 30 minutes to 24 hours, with an array of 
adverse respiratory effects including increased asthma symptoms, more 
difficulty controlling asthma, and an increase in respiratory illnesses 
and symptoms. Studies also show a connection between short-term 
exposure and increased visits to emergency departments and hospital 
admissions for respiratory illnesses, particularly in populations 
including children, the elderly, and asthmatics.
    The EPA's NAAQS for NO2 is designed to protect against 
exposure to the entire group of NOX. NO2 is the 
component of greatest concern and is used as the indicator for the 
larger group of NOX. (See 75 FR 6474.)

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

    After the promulgation of 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 
Administrator signed a final rule revising the NO2 NAAQS on 
January 22, 2010, which was published in the Federal Register on 
February 9, 2010, and became effective April 12, 2010. Based on the 
Administrator's review of the scientific evidence, including numerous 
studies published since the last review of the NO2 NAAQS, 
and taking into consideration the comments expressed by the Clean Air 
Scientific Advisory Committee and the public, the Administrator set a 
new 1-hour NO2 standard at the level of 100 parts per 
billion (ppb). In addition to establishing an averaging time and level, 
the Administrator also set a new form for the standard. The form for 
the 1-hour NO2 standard is the 3-year average of the 98th 
percentile of the annual distribution of daily maximum 1-hour average 
concentrations. The rule also retained, with no change, the current 
annual average NO2 standard of 53 ppb.
    The rule also set new requirements for the placement of 
NO2 monitors. The EPA and state agencies are currently 
working to establish an expanded network of NO2 monitors, 
expected to be deployed in 2013. NO2 concentrations near 
major roads are appreciably higher than those measured at monitors in 
the current network. Monitoring studies indicate that near-road (within 
about 50 meters) concentrations of NO2 can be 30 to 100 
percent higher than concentrations away from major roads.
    The CAA requires the EPA to complete the initial area designation 
process within 2 years of promulgating a new or revised NAAQS. However, 
if

[[Page 9534]]

the Administrator has insufficient information to make these 
designations within that time frame, the EPA has the authority to 
extend the designation process by up to 1 additional year.
    By not 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 is authorized to 
make any modifications the Administrator deems necessary. The statute 
does not define the term ``necessary,'' but the EPA interprets this to 
authorize the Administrator to modify designations that did not meet 
the statutory requirements or were 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. If the state does not agree with 
the EPA's intended modification, it then has an opportunity to respond 
to the EPA and to demonstrate why it believes the modification proposed 
by the EPA is inappropriate. Even if a state fails to provide any 
recommendation for an area, in whole or in part, the EPA still must 
promulgate a designation that the Administrator deems appropriate.
    Section 107(d)(1)(A)(i) of the CAA defines a nonattainment area as 
any area that does not meet an ambient air quality standard or that is 
contributing to ambient air quality in a nearby area that does not meet 
the standard. If an area meets either prong of this definition, then 
the EPA is obligated to designate the area as ``nonattainment.'' 
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.''
    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.\1\
---------------------------------------------------------------------------

    \1\ This view was confirmed in Catawba County v. EPA, 571 F.3d 
20 (DC Cir. 2009).
---------------------------------------------------------------------------

    Similarly, 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.
    Designation activities for federally-recognized tribes are covered 
under the authority of section 301(d) of the CAA. This provision of the 
CAA authorizes the EPA to treat eligible tribes in a similar manner as 
states. Pursuant to section 301(d)(2), we promulgated regulations, 
known as the Tribal Authority Rule (TAR), on February 12, 1999. See 63 
FR 7254, codified at 40 CFR 49 (1999). 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.
    Designation recommendations and supporting documentation for the 
NO2 NAAQS were submitted by most states and a few tribes to 
the EPA by January 22, 2011. After receiving recommendations from 
states and tribes, and after reviewing and evaluating each 
recommendation, the EPA provided a response to the states and tribes on 
June 29, 2011. In these letter responses, we indicated whether the EPA 
intended to make modifications to the initial state or tribal 
recommendations and explained the EPA's reasons for making any such 
modifications. The EPA requested that states and tribes respond to any 
proposed EPA modifications by August 29, 2011. We received comments 
from some states suggesting changes to the EPA's proposed modifications 
and providing additional information. The EPA evaluated these comments, 
and, as a result, some of the final designations reflect further 
modifications to the initial state and tribal recommendations. The 
state and tribal letters, including the initial recommendations, the 
EPA's June 2011 responses to those letters, including any 
modifications, and the subsequent state and tribal comment letters are 
in the docket for this action.
    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 June 2011 response letters. In order to gather additional 
information for the EPA to consider before making final designations, 
EPA published a notice on July 7, 2011, (76 FR 39798) which invited the 
public to comment on the EPA's intended designations. In that notice, 
the EPA provided the opportunity to all interested parties other than 
states and tribes to submit comments by August 8, 2011. State and 
tribal initial recommendations and EPA's responses, including 
modifications, were posted on a publically accessible Web site (http://www.epa.gov/airquality/nitrogenoxides/designations/index.html). 
Comments from the public and EPA's responses to comments are in the 
docket for this action.

VI. What guidance did the EPA issue and how did the EPA apply the 
statutory requirements and applicable guidance to determine area 
designations and boundaries?

    In the notice of proposed rulemaking for the revised NO2 
NAAQS (73 FR 29184), the EPA issued proposed guidance, on its approach 
to implementing the standard, including its approach to initial area 
designations. The EPA solicited comment on that guidance and, in the 
notice of final rulemaking (75 FR 6475), adopted guidance concerning 
how to designate areas for the NO2 NAAQS. In that guidance 
the EPA recommended that monitoring data using the 3 most recent years 
of quality-assured air quality data from the current monitoring 
network, which would be for the years 2008-2010, be used to identify 
violations of

[[Page 9535]]

the NO2 NAAQS. The EPA is basing these final designations on 
monitored NO2 concentrations from Federal Reference Method 
(FRM) monitors from calendar years 2008-2010.
    In the guidance, the EPA stated that in the event that a current 
NO2 monitor indicates a violation of the revised standards, 
the EPA intends to designate such areas ``nonattainment'' no later than 
2 years following promulgation of the revised standards. The EPA also 
stated that it intends to designate the rest of the country as 
``unclassifiable'' for the revised NO2 NAAQS until 
sufficient air quality data is collected from a near-roadway monitoring 
network. Once the near-roadway network is fully deployed and 3 years of 
air quality data are available, the EPA has authority under the CAA to 
redesignate areas as appropriate from ``unclassifiable'' to 
``attainment'' or ``nonattainment.'' The EPA anticipates that 
sufficient data to conduct redesignations would be available after 
2015.
    In the EPA's June 2011 response letters to state and tribal 
recommendations, the EPA stated that in response to recommendations and 
review of the 2008-2010 monitored NO2 concentrations, it 
intended to designate all areas of the U.S. as ``unclassifiable/
attainment.'' The EPA uses this designation in practice for initial 
designations to mean that available information does not indicate that 
the air quality in these areas exceeds the 2010 NO2 NAAQS.

VII. Comments

    In the EPA's June 2011 response letters to state and tribal 
recommendations, the EPA recommended that states and tribes consider 
implications for the prevention of significant deterioration of air 
quality (PSD) program when proposing their boundaries. Several states 
responded by providing suggested changes to their recommended 
boundaries. The EPA has accepted these changes and has applied them in 
these final designations.
    The EPA received comments from one state and one trade association, 
both indicating that the EPA should designate areas as ``attainment'' 
rather than ``unclassifiable/attainment.''
    The trade association commenter stated that a designation of 
``attainment'' signifies the air is healthy while a designation of 
``unclassifiable'' does not. The commenter acknowledges the concern 
that the current monitoring network is inadequate in many instances to 
determine if an area meets the 2010 NO2 NAAQS. Nonetheless, 
the commenter believes a designation of ``attainment'' is appropriate 
where current monitoring shows no violations. The commenter 
acknowledges that redesignation to ``nonattainment'' would be 
appropriate if new monitors show violations of the 2010 NO2 
NAAQS.
    The second comment, from a state, restated their recommendation 
that their entire state should be designated as ``attainment.'' In 
their comment, they provide 2007-2010 data from seven NO2 
monitors operated in the state. The commenter points out that no single 
year 98th percentile has exceeded 44 percent of the 2010 NO2 
NAAQS and design values have not exceeded 42 percent of the 2010 
NO2 NAAQS.
    After considering state and public comments on the EPA's June 2011 
response letters to state and tribal recommendations, the EPA is 
finalizing designations for all areas of the U.S. as ``unclassifiable/
attainment.'' This designation is intended to indicate that for the 
purposes of initial area designations, available information does not 
indicate that air quality in these areas exceeds the NAAQS.
    Although all existing community-based monitoring sites indicate 
attainment with the NO2 NAAQS, the existing NO2 
monitoring network does not fully portray or represent the 
NO2 concentrations near roadways. Until more complete 
information on NAAQS compliance is available, the EPA does not believe 
a designation of ``attainment'' is appropriate.

VIII. Implications of Designations for Compliance With PSD Increments 
for NO2

    The CAA's PSD requirements are designed to ensure that economic 
growth will occur in a manner consistent with preserving clean air in 
areas not currently violating the NAAQS (see CAA sections 160-169). In 
such areas, new or modified major sources of NO2 must comply 
with maximum allowable increases (increments) in concentrations of 
NO2. In some parts of the U.S., ``baseline areas'' have 
already been established for NO2 increment analysis under 
the designations associated with the existing NO2 annual 
NAAQS.\2\ The boundaries for such areas are not affected by the newly 
designated areas listed as ``unclassifiable/attainment'' for the 1-hour 
NO2 NAAQS. In addition, any increment baseline areas created 
in the future for the annual NO2 standard should be based on 
the existing designations that are associated with (and continue to 
apply to) the NO2 annual NAAQS.
---------------------------------------------------------------------------

    \2\ The concept of ``baseline areas'' and their relationship to 
the area designations is described in 40 CFR 81.300(b). The 
definition of baseline area appears in PSD regulations at 40 CFR 
52.21(b)(15)(i).
---------------------------------------------------------------------------

IX. What air quality data has the EPA used?

    The final NO2 designations contained in this action are 
based upon air quality monitoring data from calendar years 2008-2010.

X. How do designations affect Indian country?

    All counties, partial counties or Air Quality Control Regions 
listed in the table at the end of this document are designated as 
indicated. There are no areas of Indian country being designated 
nonattainment at this time.

XI. 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 and related 
decisions are provided in the docket for this rulemaking. The 
applicable EPA guidance memoranda, and copies of correspondence 
regarding this 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 our designation 
Web site at http://www.epa.gov/airquality/nitrogenoxides/designations/index.html. State-specific information is available from the EPA 
Regional Offices.

XII. Statutory and Executive Order Reviews

    Upon promulgation of a new or revised NAAQS, the CAA requires the 
EPA to designate areas as attaining or not attaining the NAAQS. The CAA 
then specifies requirements for areas based on whether such areas are 
attaining or not attaining the NAAQS. In this final rule, the EPA 
assigns designations to areas as required.

A. Executive Order 12866: Regulatory Planning and Review and Executive 
Order 13563: Improving Regulation and Regulatory Review

    This action will respond to the requirement to promulgate air 
quality designations after promulgation of a NAAQS. This type of action 
is exempt from review under Executive Orders 12866 (58 FR 51735, 
October 4, 1993) 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

[[Page 9536]]

Act, 44 U.S.C. 3501 et seq. Burden is defined at 5 CFR 1320.3(b). This 
rule responds to the requirement to promulgate air quality designations 
after promulgation of a new or revised NAAQS. This requirement is 
prescribed in the CAA section 107. The present final rule does not 
establish any new information collection requirements.

C. Regulatory Flexibility Act

    This final rule is not subject to the Regulatory Flexibility Act 
(RFA), which generally requires an agency to prepare a regulatory 
flexibility analysis for any rule that will have a significant economic 
impact on a substantial number of small entities. The RFA applies only 
to rules subject to notice-and-comment rulemaking requirements under 
the Administrative Procedure Act (APA) or any other statute. This rule 
is not subject to notice-and-comment requirements under the APA or any 
other statute because the rule is subject to CAA section 107(d)(2)(B), 
which does not require that the agency issue a notice of proposed 
rulemaking before issuing this rule.

D. Unfunded Mandates Reform Act

    This action contains no federal mandate 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. The action imposes no enforceable duty on any state, local or 
tribal governments 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. It does not create 
any additional requirements beyond those of the CAA and NO2 
NAAQS (40 CFR 50.11). The CAA establishes the process whereby states 
take primary responsibility in developing plans to meet the 
NO2 NAAQS.

E. Executive Order 13132: Federalism

    This final rule 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 Executive Order 13132. The CAA establishes the process 
whereby states take primary responsibility in developing plans to meet 
the NO2 NAAQS. This rule will not modify the relationship of 
the states and the EPA for purposes of developing programs to implement 
the NO2 NAAQS. Thus, Executive Order 13132 does not apply to 
this rule.

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

    This action does not have tribal implications, as specified in 
Executive Order 13175 (65 FR 67249, November 9, 2000). This rule 
concerns the designation of areas for the 1-hour NO2 NAAQS. 
The CAA provides for states and eligible tribes to develop plans to 
regulate emissions of air pollutants within their areas, as necessary, 
based on the designations. The TAR provides tribes the opportunity to 
apply for eligibility to develop and implement CAA programs such as 
programs to attain and maintain the NO2 NAAQS, but it leaves 
to the discretion of the tribe the decision of whether to apply to 
develop these programs and which programs, or appropriate elements of a 
program, the tribe will seek to adopt. This rule does not have a 
substantial direct effect on one or more Indian tribes. It does not 
create any additional requirements beyond those of the NO2 
NAAQS (40 CFR section 50.11). This rule establishes the designation for 
certain areas of the country for the NO2 NAAQS but no areas 
in Indian country are being designated nonattainment under this rule. 
Consequently, no tribe has any immediate requirement to implement a CAA 
program to attain the 1-hour NO2 NAAQS in Indian Country at 
this time. Furthermore, this rule does not affect the relationship or 
distribution of power and responsibilities between the federal 
government and Indian tribes. The CAA and the TAR establish the 
relationship of the federal government and tribes in developing plans 
to attain the NAAQS, and this rule does nothing to modify that 
relationship. Thus, Executive Order 13175 does not apply to this 
action.
    Although Executive Order 13175 does not apply to this action, the 
EPA communicated with tribal leaders and environmental staff regarding 
the designations process. The EPA also sent individualized letters to 
all federally recognized tribes to explain the designation process for 
the 2010 NO2 NAAQS, to provide the EPA designations 
guidance, and to offer consultation with the EPA. The EPA provided 
further information to tribes through presentations at the National 
Tribal Forum and through participation in National Tribal Air 
Association conference calls. The EPA also sent individualized letters 
to all federally recognized tribes that submitted recommendations to 
the EPA about the EPA's intended designations for the NO2 
standards and offered tribal leaders the opportunity for consultation. 
These communications provided opportunities for tribes to voice 
concerns to the EPA about the general designations process for the 
NO2 NAAQS, as well as concerns specific to a tribe, and 
informed the EPA about key tribal concerns regarding designations as 
the rule was under development.

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

    The EPA interprets Executive Order 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 Executive Order has the potential to influence the regulation. 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 (66 FR 28355 
(May 22, 2001)), because it is not a significant regulatory action 
under Executive Order 12866.

I. National Technology Transfer and Advancement Act (NTTAA)

    Section 12(d) of the NTTAA of 1995, Public Law 104-113, section 
12(d) (15 U.S.C. 272 note) directs the EPA to use voluntary consensus 
standards (VCS) in its regulatory activities unless to do so would be 
inconsistent with applicable law or otherwise impracticable. Voluntary 
consensus standards are technical standards (e.g., materials 
specifications, test methods, sampling procedures, and business 
practices) that are developed or adopted by VCS bodies. The NTTAA 
directs the EPA to provide Congress, through OMB, explanations when the 
Agency decides not to use available and applicable VCS.
    This action does not involve technical standards. Therefore, the 
EPA did not consider the use of any VCS.

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

    Executive Order 12898 (59 FR 7629 (Feb. 16, 1994)) establishes 
federal executive policy on environmental justice. Its main provision 
directs

[[Page 9537]]

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 their programs, policies, and 
activities on minority populations and low-income populations in the 
U.S.
    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 all areas where available information indicates a 
violation of the NO2 NAAQS, this action protects all those 
residing, working, attending school, or otherwise present in those 
areas regardless of minority or economic status.
    EPA has determined that this final rule will not have 
disproportionately high and adverse human health or environmental 
effects on minority or low-income populations because it increases the 
level of environmental protection for all affected populations without 
having any disproportionately high and adverse human health or 
environmental effects on any population, including any minority or low-
income population

K. Congressional Review Act

    The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the 
Small Business Regulatory Enforcement Fairness Act of 1996, generally 
provides that before a rule may take effect, the agency promulgating 
the rule must submit a rule report, which includes a copy of the rule, 
to each House of the Congress and to the Comptroller General of the 
U.S. The EPA will submit a report containing this rule and other 
required information to the U.S. Senate, the U.S. House of 
Representatives, and the Comptroller General of the U.S. prior to 
publication of the rule in the Federal Register. A major rule cannot 
take effect until 60 days after it is published in the Federal 
Register. This action is not a ``major rule'' as defined by 5 U.S.C. 
804(2). This rule will be effective February 29, 2012.

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 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 rule designating areas for the 2010 NO2 NAAQS is 
``nationally applicable'' within the meaning of section 307(b)(1). This 
rule establishes designations for areas across the U.S. for the 2010 
NO2 NAAQS. At the core of this rulemaking is EPA's 
interpretation of the definition of nonattainment under section 
107(d)(1) of the CAA, and its application of that interpretation to 
areas across the country.
    For the same reasons, the Administrator also is 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 
rulemaking 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 rule 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.
