2013-18835. Air Quality Designations for the 2010 Sulfur Dioxide (SO2) Primary National Ambient Air Quality Standard

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Final rule.

SUMMARY:

This rule establishes air quality designations for certain areas in the United States for the 2010 primary Sulfur Dioxide (SO₂) National Ambient Air Quality Standard (NAAQS). The EPA is issuing this rule to identify areas that, based on recorded air quality monitoring data showing violations of the NAAQS, do not meet the 2010 SO₂ NAAQS and areas that contribute to SO₂ air pollution in a nearby area that does not meet the SO₂ NAAQS. At this time, the EPA is designating as nonattainment most areas in locations where existing monitoring data from 2009-2011 indicate violations of the 1-hour SO₂ standard. The EPA intends to address in separate future actions the designations for all other areas for which the agency is not yet prepared to issue designations and that are consequently not addressed in this final rule. The Clean Air Act (CAA) directs areas designated nonattainment by this rule to undertake certain planning and pollution control activities to attain the NAAQS as expeditiously as practicable.

DATES:

Effective Date: The effective date of this rule is October 4, 2013.

II. What is the purpose of this document?

The purpose of this action is to announce and promulgate designations and boundaries for certain areas of the country not meeting the 2010 SO₂ NAAQS based on available information, in accordance with the requirements of the CAA. The initial list of areas being designated nonattainment in each state and the boundaries of each area appear in the tables within the regulatory text.

This notice identifies the 29 initial areas being designated as nonattainment areas for the 2010 SO₂ NAAQS. The basis for designating each area as “nonattainment” is monitored air quality data from calendar years 2009-2011 indicating a violation of the NAAQS in the area. For these areas being designated nonattainment, the CAA directs states to develop State Implementation Plans (SIPs) that meet the requirements of sections 172(c) and 191-192 of the CAA and provide for attainment of the NAAQS as expeditiously as practicable, but no later than October 4, 2018. The CAA directs states to submit these SIPs to the EPA within 18 months of the effective date of these designations, i.e., by April 6, 2015.

III. What is sulfur dioxide?

SO₂ is one of a group of highly reactive gasses known as “oxides of sulfur” (SO_X). The largest sources of SO₂ emissions are from fossil fuel combustion at power plants (73 percent) and other industrial facilities (20 percent). Smaller sources of SO₂ emissions include industrial processes, such as extracting metal from ore, and the burning of high sulfur containing fuels by locomotives, large ships and non-road equipment. SO₂ is linked with a number of adverse effects on the respiratory system.

IV. What is the 2010 SO₂ NAAQS and what are the health concerns that it addresses?

The Administrator signed a final rule revising the primary SO₂ NAAQS on June 2, 2010. The rule was published in the Federal Register on June 22, 2010 (75 FR 35520), and became effective on August 23, 2010. Based on the Administrator's review of the air quality criteria for oxides of sulfur and the primary NAAQS for oxides of sulfur as measured by SO₂, the EPA revised the primary SO₂ NAAQS to provide requisite protection of public health with an adequate margin of safety. Specifically, the EPA established a new 1-hour SO₂ standard at a level of 75 parts per billion (ppb), which is met at an ambient air quality monitoring site when the 3-year average of the annual 99th percentile of 1-hour daily maximum concentrations is less than or equal to 75 ppb, as determined in accordance with Appendix T of 40 CFR part 50. 40 CFR 50.17(a)-(b). The EPA also established provisions to revoke both the existing 24-hour and annual primary SO₂ standards, subject to certain conditions. 40 CFR 50.4(e).

Current scientific evidence links short-term exposures to SO₂, ranging from 5 minutes to 24 hours, with an array of adverse respiratory effects including bronchoconstriction and increased asthma symptoms. These effects are particularly important for asthmatics at elevated ventilation rates (e.g., while exercising or playing). Studies also show a connection between short-term exposure and increased visits to emergency departments and hospital admissions for respiratory illnesses, particularly in at-risk populations including children, the elderly and asthmatics.

The EPA's NAAQS for SO₂ is designed to protect against exposure to the entire group of SO_X. SO₂ is the component of greatest concern and is used as the indicator for the larger group of gaseous SO_X. Other gaseous SO_X (e.g., SO₃) are found in the atmosphere at concentrations much lower than SO₂.

Emissions that lead to high concentrations of SO₂ generally also lead to the formation of other SO_X. Control measures that reduce SO₂ can generally be expected to reduce people's exposures to all gaseous SO_X. This may also have the important co-benefit of reducing the formation of fine sulfate particles, which pose significant public health threats. SO_X can react with other compounds in the atmosphere to form small particles. These particles penetrate deeply into sensitive parts of the lungs and can cause or worsen respiratory disease, such as emphysema and bronchitis, and can aggravate existing heart disease, leading to increased hospital admissions and premature death.^[1] The EPA's NAAQS for particulate matter are designed to provide protection against these health effects.

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 process for designating areas following promulgation of a new or revised NAAQS is contained in section 107(d) of the CAA. The CAA requires the EPA to complete the initial designations process within 2 years of promulgating a new or revised standard. If the Administrator has insufficient information to make these designations by that deadline, the EPA has the authority to extend the deadline for completing designations by up to 1 year. On July 27, 2012, the EPA announced that it had insufficient information to complete the designations for the 1-hour SO₂ standard within 2 years and extended the designations deadline to June 3, 2013.

At this time, the EPA is initially designating as nonattainment most areas in locations where existing monitoring data from 2009-2011 indicate violations of the 1-hour SO₂ standard. In some cases, we have had to use data from a different three-year period or are still evaluating whether data from 2009-2011 are influenced by exceptional events. In separate future actions, the EPA intends to address the designations for all other areas for which the agency is not yet prepared to issue designations and that are consequently not addressed in this final rule. With input from a diverse group of stakeholders, the EPA has developed a comprehensive implementation strategy for the future SO₂ designations actions that focuses resources on identifying and addressing unhealthy levels of SO₂ in areas where people are most likely to be exposed to violations of the standard. For informational purposes, the strategy is available at: http://www.epa.gov/​airquality/​sulfurdioxide/​implement.html. The EPA plans to continue to work closely with state, tribal and local air quality management agencies to ensure health-protective, commonsense implementation of the 1-hour SO₂ NAAQS.

By not later than 1 year after the promulgation of a new or revised NAAQS, CAA section 107(d)(1)(A) provides that 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. During this period of no less than 120 days, if the state does not agree with the EPA's modification, it has an opportunity to respond to the EPA and to demonstrate why it believes the modification proposed by the EPA is inappropriate, as contemplated by section 107(d)(1)(B)(ii). 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, 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 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.”

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.^[2]

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 tribal governments 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), 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.

To date, six tribes have applied under the TAR for eligibility to submit its own recommendations under section 107(d). Nonetheless, the EPA invited all tribes to submit recommendations concerning designations for the 2010 SO₂ NAAQS. The EPA worked with the tribes that requested an opportunity to submit designation recommendations. Tribes were provided an opportunity to submit their own recommendations and supporting documentation and could also comment on state recommendations and the EPA modifications.

Designation recommendations and supporting documentation were submitted by most states and several tribes to the EPA by June 3, 2011. After receiving these recommendations, and after reviewing and evaluating each recommendation, the EPA provided a response to the states and tribes on February 7, 2013.^[3] 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. For the majority of the areas, the EPA agreed with the state's recommended boundary. The EPA requested that states and tribes respond to any proposed EPA modifications by April 8, 2013. The EPA received comments from some states suggesting changes to the EPA's proposed modifications and providing additional information. The EPA evaluated these comments, and all of the timely supporting technical information provided. As a result, and based on that input and analysis, some of the final designations reflect further modifications to the initial state recommendations. The state and tribal letters, including the initial recommendations, the EPA's February 2013 responses to those letters, any modifications, and the subsequent state 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 February 2013 response letters. In order to gather additional information for the EPA to consider before making final designations, the EPA published a notice on February 15, 2013 (78 FR 1124) which invited the public to comment on the EPA's intended designations. In the notice, the EPA stated that public comments must be received on or before March 18, 2013. The EPA received several requests from stakeholders for additional time to prepare their comments. Some of the requesters noted that the original 30-day comment period 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. Taking that into consideration, the EPA extended the public comment period to April 8, 2013. State and tribal initial recommendations and the EPA's responses, including modifications, were posted on a publically accessible Web site (http://www.epa.gov/​so2designations). Timely comments from the public and the EPA's responses to significant 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 SO₂ NAAQS (74 FR 64810; December 8, 2009), 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 35520; June 22, 2010), provided further guidance concerning implementation of the standard and how to identify nonattainment areas and boundaries for the SO₂ NAAQS. Subsequently, on March 24, 2011, the EPA provided additional designations guidance to assist states with making their recommendations for area designations and boundaries.^[4] In that guidance, the EPA recommended that monitoring data from the most recent three consecutive years be used to identify a violation of the SO₂ NAAQS. This is appropriate because the form of the SO₂ NAAQS is calculated as a 3-year average of the 99th percentile of the yearly distribution of 1-hour daily maximum SO₂ concentrations (specifically the most recent 3 consecutive years).^[5] The EPA is basing these initial final designations on monitored SO₂ concentrations from Federal Reference Method and Federal Equivalent Method monitors that are sited and operated in accordance with 40 CFR Parts 50 and 58. The EPA notes that data from 2008-2010 were the most recent data available to states and tribes when they made their recommendations to the EPA in June 2011. Accordingly, although the determination of whether an area violates the standard was based on 2009-2011 data, the EPA considered state recommendations and data from 2008-2010, as appropriate, in determining boundaries for nonattainment areas.

In the guidance, the EPA stated that the perimeter of a county containing a violating monitor would be the initial presumptive boundary for nonattainment areas, but also stated that the state, tribe and/or the EPA could conduct additional area-specific analyses that could justify establishing either a larger or smaller area. The EPA indicated that the following factors should be considered in an analysis of whether to exclude portions of a county and whether to include additional nearby areas outside the county as part of the designated nonattainment area: (1) Air quality data; (2) emissions-related data; (3) meteorology; (4) geography/topography; and (5) jurisdictional boundaries, as well as other available data. States and tribes may identify and evaluate other relevant factors or circumstances specific to a particular area.

Most states and several tribes submitted their designations recommendations in June 2011. In each case, the EPA reviewed the state recommendations and, where appropriate, the EPA accepted the state's recommendations. However, where the EPA determined that changes were necessary to a state's initial recommendation, we conveyed those preliminary determinations to the state in February 2013, and have worked with states to further review appropriate boundaries.

VII. What air quality data has the EPA used?

The final SO₂ designations contained in this action are based upon violations of the NAAQS determined by air quality monitoring data from calendar years 2009-2011, except where it was necessary or appropriate to use a different three-year period. The form of the standard requires a calculation of monitoring values from 3 consecutive years. The 1-hour primary standard is violated at an ambient air quality monitoring site when the 3-year average of the annual 99th percentile of the daily maximum 1-hour average concentrations exceeds 75 ppb, as determined in accordance with appendix T of 40 CFR part 50. For comparison to the level of the standard, ambient air quality shall be measured by a reference method based on appendix A or A-1, or by a Federal Equivalent Method designated in accordance with 40 CFR part 53.

VIII. How do designations affect Indian Country?

All counties, partial counties or Air Quality Control Regions listed in the tables within the regulatory text are designated as indicated. For the first round of SO₂ designations, the EPA is only designating certain nonattainment areas shown to be violating the NAAQS based on monitored data. There are no areas in Indian Country being designated nonattainment at this time. All remaining areas, including areas of Indian Country, for which the EPA is not yet prepared to issue final designations will be addressed in a subsequent round of designations.

IX. 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, applicable EPA's guidance memoranda, 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 the agency's SO₂ Designations Web site at http://www.epa.gov/​so2designations. Area-specific questions can be addressed to the EPA Regional Offices.

X. 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 selected areas as required.

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

This action responds to the CAA requirement to promulgate air quality designations after promulgation of a new or revised NAAQS. This type of action is exempt from review under Executive Orders 12866 (58 FR 51735, October 4, 1993) and 13563 (67 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 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 of title 1. This action does not establish any new information collection apart from that already required by law.

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 action is not subject to notice-and-comment requirements under the APA or any other statute because the action is not subject to the APA. CAA section 107(d)(2)(B) does not require the EPA to issue a notice of proposed rulemaking before issuing this final action.

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 SO₂ NAAQS (40 CFR 50.17); therefore, no UMRA analysis is needed. This action establishes nonattainment designations for certain areas of the country for the 2010 SO₂ NAAQS. The CAA requires states to develop plans, including control measures, based on the designations for areas within the state.

The EPA believes that any new controls imposed as a result of this action will not cost in the aggregate $100 million or more annually. Thus, this federal action will not impose mandates that will require expenditures of $100 million or more in the aggregate in any 1 year.

E. Executive Order 13132: Federalism

This final 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 Executive Order 13132. The CAA establishes the process whereby states take primary responsibility in developing plans to meet the SO₂ NAAQS in areas designated nonattainment by this action. This action will not modify the relationship of the states and the EPA for purposes of developing programs to attain and maintain the SO₂ NAAQS. Thus, Executive Order 13132 does not apply to this action.

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 action concerns the designation of certain areas as nonattainment for the 2010 SO₂ NAAQS, but no areas of Indian Country are being designated by this action. Because this action does not have tribal implications, Executive Order 13175 does not apply.

Although Executive Order 13175 does not apply to this rule, 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 SO₂ 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 SO₂ 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 2010 SO₂ 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 action is not subject to Executive Order 13045 (62 FR 19885, April 23, 1997) because it is not an economically significant regulatory action as defined in Executive Order 12866. While not subject to the Executive Order, this final action may be especially important for asthmatics, including asthmatic children, living in SO₂ nonattainment areas because respiratory effects in asthmatics are among the most sensitive health endpoints for SO₂ exposure. Because asthmatic children are considered a sensitive population, the EPA evaluated the potential health effects of exposure to SO₂ pollution among asthmatic children as part of the EPA's prior action establishing the 2010 SO₂ NAAQS. These effects and the size of the population affected are summarized in the EPA's final SO₂ NAAQS rules. See http://www.epa.gov/​ttn/​naaqs/​standards/​so2/​fr/​20100622.pdf.

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. VCS 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 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 areas where available information indicate a violation of the 2010 SO₂ 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.

The 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 action 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 October 4, 2013.

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 2010 SO₂ 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 2010 SO₂ NAAQS. At the core of this final action is the 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 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 DC 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.
