### Federal Register/Vol. 77, No. 98/Monday, May 21, 2012/Rules and Regulations ENVIRONMENTAL PROTECTION AGENCY 40 CFR Part 81 [EPA-HQ-OAR-2008-0476; FRL-9668-2] RIN 2060-AP37 Air Quality Designations for the 2008 Ozone National Ambient Air Quality Standards AGENCY: 

### Environmental Protection Agency (EPA). ACTION: Final 

### rule. SUMMARY: This rule establishes initial air quality designations for most areas in the United States, including areas of Indian country, for the 2008 primary and secondary national ambient air quality standards (NAAQS) for ozone. The designations for several counties in Illinois, Indiana, and Wisconsin that the EPA is considering for inclusion in the Chicago nonattainment area will be designated in a subsequent action, no later than May 31, 2012. Areas designated as nonattainment are also being classified by operation of law according to the severity of their air quality problems. The classification categories are Marginal, Moderate, Serious, Severe, and Extreme. The EPA is establishing the air quality thresholds that define the classifications in a separate rule that the EPA is signing and publishing in the Federal Register on the same schedule as these designations. In accordance with that separate rule, six nonattainment areas in California are being reclassified to a higher classification. DATES:

### II. What is the purpose of this action?

The purpose of this action is to announce and promulgate initial area designations for most areas of the country with respect to the 2008 primary and secondary NAAQS for ozone, in accordance with the requirements of Clean Air Act (CAA) section 107(d). The EPA is designating areas as either nonattainment, unclassifiable, or unclassifiable/ attainment. In addition, the nonattainment areas are classified by operation of law according to the severity of their ozone air quality problems and six areas in California are being reclassified immediately to a higher classification. The classification categories are Marginal, Moderate, Serious, Severe, and Extreme. The EPA is establishing the air quality thresholds that define the classifications in a separate rule titled, "Implementation of the 2008 National Ambient Air Quality Standards for Ozone: Nonattainment Area Classifications Approach, Attainment Deadlines and Revocation of the 1997 Ozone Standards for Transportation Conformity Purposes" (Classifications Rule). In that separate rule, the EPA also codified the immediate reclassification of six areas in California. (See 40 CFR 51.1103(d).) The list of all areas being designated in each state and in areas of Indian county appear in the tables at the end of this final rule (amendments to 40 CFR 81.301-356). For areas designated as nonattainment, the tables include the area's classification by operation of law or the area's reclassification in accordance with 40 CFR 51.1103(d).

In this action, the EPA is designating 45 areas as nonattainment. Seven of the areas are multi-state areas. The EPA is designating one area, Uinta Basin, WY, as unclassifiable because there is existing non-regulatory monitoring in the area that detected levels of ozone that exceed the NAAQS. Regulatory monitoring has been conducted in that area since April 2011, and thus there are not yet three consecutive years of certified ozone monitoring data available that can be used to determine the area's attainment status. Consistent with previous initial area designations for ozone, the EPA is designating all the remaining state areas and 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 four areas of Indian country separately from their adjacent/ surrounding state areas.' The lands of the Pechanga Tribe and the Morongo Tribe in Southern California are being designated as separate nonattainment areas, while two additional areas in Indian country are being designated as separate unclassifiable/attainment areas.

The EPA is basing the designations on the most recent certified ozone air

### quality monitoring data and an evaluation of factors to assess contributions to nonattainment in nearby areas. State areas designated as nonattainment are subject to planning and emission reduction requirements as specified in the CAA. Requirements vary according to an area's classification. The EPA will be proposing shortly an implementation rule to assist states in the development of state implementation plans for attaining the ozone standards. III. What is ozone and how is it formed?

Ground-level ozone, 03, 

### is a gas that is formed by the reaction of volatile organic compounds (VOCs) and oxides of nitrogen (NOx) in the atmosphere in the presence of sunlight. These precursor emissions are emitted by many types of pollution sources, including power plants and industrial emissions sources, on-road and off-road motor vehicles and engines, and smaller sources, collectively referred to as area sources. Ozone is predominately a summertime air pollutant. However, high ozone concentrations have also been observed in cold months, where a few high elevation areas in the Western U.S. have experienced high levels of local VOC and NOx emissions that have formed ozone when snow is on the ground and temperatures are near or below freezing. Ozone and ozone precursors can be transported to an area from sources in nearby areas or from sources located hundreds of miles away. For purposes of determining ozone nonattainment area boundaries, the CAA requires the EPA to include areas that contribute to nearby violations of the NAAQS. IV. What are the 2008 ozone NAAQS and the health and welfare concerns they address?

On March 12, 2008, the EPA revised both the primary and secondary NAAQS for ozone to a level of 0.075 parts per million (ppm) (annual fourth-highest daily maximum 8-hour average concentration, averaged over 3 years) to provide increased protection ofpublic health and the environment.2 The 2008 ozone NAAQS retains the same general form and averaging time as the 0.08 ppm NAAQS set in 1997, but is set at a more protective level.

Ozone exposure also has been associated with increased susceptibility to respiratory infections, medication use by asthmatics, doctor visits, and emergency department visits and

### Federal Register/Vol. 77, No. 98/Monday, May 21, 2012/Rules and Regulations hospital admissions for individuals with respiratory disease. Ozone exposure may also contribute to premature death, especially in people with heart and lung disease. The secondary ozone standard was revised to protect against adverse welfare effects including impacts to sensitive vegetation and forested ecosystems. V. What are the CAA requirementsfor air quality designations?

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.

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. These notifications are commonly known as the "120-day letters." Ifthe state does not agree with the EPA's intended modification, it then has an opportunity to respond to the EPA to demonstrate why it believes the modification proposed by the EPA is inappropriate. Even ifa 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 (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." 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 ozone, 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.

The EPA believes that section 107(d) provides the agency with discretion to determine how best to interpret the terms "contributes to" and "nearby" in the definition of a nonattainment area 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.

Section 301(d) of the CAA authorizes the EPA to approve eligible Indian tribes to implement provisions of the CAA on Indian reservations and other areas within the tribes' jurisdiction. The Tribal Authority Rule (TAR) (40 CFR Part 49), which implements section 301(d) of the CAA, sets forth the criteria and process for tribes to apply to the EPA for eligibility to administer CAA programs. 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. VI. What is the chronology for this designations rule and what guidance did the EPA provide?

Within one year after a new or revised air quality standard is established, the

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

### CAA requires the governor of each state to submit to the EPA a list of all areas in the state, with recommendations for whether each area meets the standard. On December 4, 2008, the EPA issued guidance for states and tribal agencies to use for this purpose. (See memorandum from Robert J. Meyers, Principal Deputy Assistant Administrator, to Regional Administrators, Regions I-X, titled, "Area Designations for the 2008 Revised Ozone National Ambient Air Quality Standards.) The guidance provided the anticipated timeline for designations and identified important factors that the EPA recommended states and tribes consider in making their recommendations. These factors include air quality data, emissions data, traffic and commuting patterns, growth rates and patterns, meteorology, geography/ topography, and jurisdictional boundaries. In the guidance, the EPA asked that states and tribes submit their designation recommendations, including appropriate area boundaries, to the EPA by March 12, 2009. Later in the process, the EPA issued 2 new guidance memoranda related to designating areas of Indian county. (See December 20, 2011, memorandum from Stephen D. Page, Director, Office of Air Quality Planning and Standards, to Regional Air Directors, Regions I-X, titled, "Policy for Establishing Separate Air Quality Designations for Areas of Indian Country," and December 20, 2011, memorandum from Stephen D. Page, Director, Office of Air Quality Planning and Standards, to Regional Air Directors, Regions I-X, titled, "Guidance to Regions for Working with Tribes during the National Ambient Air Quality Standards (NAAQS) Designations Process.")

Under the initial schedule, the EPA intended to complete the initial designations for the 2008 ozone NAAQS on a 2-year schedule, by March 12, 2010. On September 16, 2009, the EPA announced that it would initiate a rulemaking to reconsider the 2008 ozone NAAQS for various reasons, including the fact that the 0.075 ppm level fell outside of the range recommended by the Clean Air Scientific Advisory Committee, the independent group that provides advice to the EPA Administrator on the technical bases for the EPA's NAAQS. The EPA signed the proposed reconsideration on January 6, 2010. (See 75 FR 2938; January 19, 2010.) Because of the significant uncertainty the ozone NAAQS reconsideration created regarding the continued applicability of the 2008 NAAQS, the EPA determined there was insufficient information to 30090

### Federal Register/Vol. 77, No. 98/Monday, May 21, 2012/Rules and Regulations designate areas within 2years of promulgation of the NAAQS. Therefore, the EPA used its authority under CAA section 107(d)(1)(B) to extend the deadline for designating areas by 1 year, until March 12, 2011. (See 75 FR 2936; January 19, 2010.) The EPA has not taken final action on the proposed reconsideration; thus, the current NAAQS for ozone remains at 0.075 ppm, as established in 2008.

After the March 12, 2011, designation deadline passed, WildEarth Guardians and Elizabeth Crowe (WildEarth Guardians) filed a lawsuit seeking to compel the EPA to take action to designate areas for the 2008 ozone NAAQS. WildEarth Guardians and Elizabeth Crowev. Jackson (D. Ariz. 11- CV-01661). The EPA and WildEarth Guardians settled the case by entering into a consent decree that requires the EPA Administrator to sign a final rule designating areas for the 2008 ozone NAAQS by May 31, 2012.

On September 22, 2011, the EPA issued a memorandum to clarify for state and local agencies the status of the 2008 ozone NAAQS and to outline plans for moving forward to implement them. The EPA indicated that it would proceed with initial area designations for the 2008 NAAQS, and planned to use the recommendations states made in 2009 as updated by the most current, certified air quality data from 2008- 2010. While the EPA did not request that states submit updated designation recommendations, the EPA provided the opportunity for states to do so. Several states chose to update their recommendations, and some requested that the EPA base designations for their areas on certified air quality data from 2009-2011, and committed to certify the 2011 data earlier than the May 1 deadline for annual air monitoring certification under 40 CFR part 58.15(a)(2) so that the EPA would have sufficient time to consider the data in making decisions on designations and nonattainment area boundaries.

On or about December 9, 2011, the EPA sent letters to Governors and Tribal leaders notifying them of the EPA's preliminary response to their designation recommendations and to inform them of the EPA's approach for completing the designations for the 2008 ozone NAAQS. The EPA requested that states submit any additional information that they wanted the EPA to consider by February 29, 2011, including any certified 2011 air quality monitoring data. On January 31, 2011, the EPA sent revised 120-day letter responses to Illinois, Indiana, and Wisconsin based on updated ozone air quality data for 2009-2011, submitted by the state of Illinois two days before the EPA sent the December 9, 2011, letters. Given the timing of Illinois' submission of certified data, EPA was not able to consider the information in the December 9, 2011, letters. After reviewing the new information, which indicated a violation of the ozone NAAQS at a monitor in the Chicago area, the EPA sent letters on January 31, 2012 notifying Illinois, Indiana, and Wisconsin that it intended to designate certain counties, identified in those letters, as nonattainment for the 2008 ozone NAAQS. The EPA cannot finalize a designation for those areas until 120 days following the letters. Therefore, the EPA will be designating the Illinois, Indiana, and Wisconsin counties identified in the January 31, 2011, letters in a separate rule that will be signed no later than May 31, 2012.

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 120-day response letters to states and tribes. The EPA announced a 30-day public comment period in the Federal Register on December 20, 2011 (76 FR 78872). The comment period was subsequently extended until February 3, 2012 (77 FR 2677; January 19, 2012). On February 14, 2012 (77 FR 8211), the EPA reopened the public comment period for the limited purpose of inviting comment on the EPA's revised responses to Illinois, Indiana, and Wisconsin. State and tribal recommendations and the EPA's preliminary responses were posted on EPA's Web site at http:// www.epa.gov/ozonedesignationsand are available in the docket for the designations action. Comments from the states, tribes and the public, and EPA's responses to significant comments, are also in the docket. VII. What air quality data has the EPA used to designate areas for the 2008 ozone NAAQS?

The final ozone designations are based primarily on certified air quality monitoring data from calendar years 2008-2010, which was the most recent certified data available to the EPA at the time the EPA notified the states of its intended modifications to their recommendations. Under 40 CFR 58.16, states are required to report all monitored ozone air quality data and associated quality assurance data within 90 days after the end of each quarterly reporting period, and under 40 CFR part 58.15(a)(2) states are required to submit annual summary reports and a data certification letter to the EPA by May 1 for ozone air quality data collected in the previous calendar year. States generally had not completed these requirements for calendar year 2011 ozone air quality data when the EPA notified states of our intended designations on December 9, 2011. In certain cases, states included as part of their designation recommendations a request that the EPA consider monitoring data from 2009-2011 in making final designation decisions. In these requests, they indicated to the EPA what they expected their certified ozone air quality data would show regarding whether an area was attaining the standard, and for designations purposes they committed to certifying their 2011 data no later than February 29, 2012, so that the EPA would have sufficient time to consider it. Thus, for those areas, the EPA considered the state's preliminary representation of 2011 data in sending the 120-day notification letter. We have verified these representations in making our final designations decisions. VIII. What are the ozone air quality classifications?

In accordance with CAA section 181(a)(1), each area designated as nonattainment for the 2008 ozone NAAQS is classified by operation of law at the same time as the area is designated by the EPA. Under Subpart 2 ofpart D of title I of the CAA, state planning and emissions control requirements for ozone are determined, in part, by a nonattainment area's classification. The ozone nonattainment areas are classified based on the severity of their ozone levels (as determined based on the area's "design value," which represents air quality in the area for the most recent 3years). 4 

### The possible classifications are Marginal, Moderate, Serious, Severe, and Extreme. Nonattainment areas with a "lower" classification have ozone levels that are closer to the standard than areas with a "higher" classification. Areas in the lower classification levels have fewer and/or less stringent mandatory air quality planning and control requirements than those in higher classifications. The final Classifications Rule, which is being signed at the same time as the designations rule and being published and effective at the same time or before the designations, establishes the classification thresholds for each classification category for purposes of the 2008 NAAQS and explains the EPA's methodology for calculating the thresholds. In addition, in the

4The air quality design value for the 8-hour ozone NAAQS is the 3-year average of the annual 4th highest daily maximum 8-hou r average ozone concentration. See 40 CFR part 50, Appendix i. 

### 30091

### Federal Register/Vol. 77, No. 98/Monday, May 21, 2012/Rules and Regulations Classifications Rule, the EPA promulgated a regulation, 40 CFR 51.1103(d), that immediately reclassifies 6 areas in California to higher classifications. The classification for each nonattainment area designated for the 2008 ozone NAAQS is shown in the 40 CFR part 81 tables at the end of this designations rule. IX. What is the reclassification of six California nonattainment areas?

The final Classifications Rule addresses the reclassification for the 2008 ozone NAAQS of selected areas in California that had voluntarily reclassified under the 1997 ozone NAAQS. In accordance with the final Classifications Rule, the following areas are being voluntarily reclassified to a higher classification for purposes of the 2008 NAAQS pursuant to that rule: Serious-Ventura County, CA; SevereLos Angeles-San Bernardino Counties (West Mojave Desert), Riverside County (Coachella Valley), and Sacramento Metro, CA; Extreme-Los Angeles-South Coast Air Basin, and San Joaquin Valley, CA. These classifications are reflected in the tables at the end of this final rule (amendments to 40 CFR 81.301-356). X. Can states request that areas within 5 percent of the upper or lower limit of a classification threshold be reclassified?

Under CAA section 181(a)(4), an ozone nonattainment area may be reclassified to a higher or lower classification (also known as a classification bump up or a bump down) "if an area classified under paragraph (1) (Table 1) would have been classified in another category if the design value in the area were 5 percent greater or 5 percent less than the level on which such classification was based." The section also states that "In making such adjustment, the Administrator may consider the number of exceedances of the national primary ambient air quality standard for ozone in the area, the level of pollution transport between the area and other affected areas, including both intrastate and interstate transport, and the mix of sources and air pollutants in the area."

As noted in the preamble to the rule designating and classifying areas following enactment of the CAA Amendments of 1990, the section 181(a)(4) provisions grant the Administrator broad discretion in making or determining not to make, a reclassification. (See 56 FR 56698; November 6, 1991.) As part of the 1991 action, the EPA developed criteria to evaluate whether it is appropriate to reclassify a particular area. (See list below and at 56 FR 56698.) Because section 181(b)(3) provides that the EPA must grant any state request to reclassify an area into a higher classification, the EPA focused these criteria primarily on how the EPA would assess requests for a lower classification. In 1991, EPA approved reclassifications when the area met the first requirement (a request by the state to EPA) and at least some of the other criteria, and did not violate any of the criteria (emissions reductions, trends, etc.). The EPA used the same method and criteria once again to evaluate reclassification requests under section 181(a)(4) for purposes of the 1997 ozone NAAQS. The EPA intends to continue to use this same approach for purposes of evaluating any request for a reclassification for the 2008 ozone NAAQS. For reclassifications downwards, states may only request a reclassification to the next lower classification, and air quality data from prior years cannot be used as justification to be reclassified to an even lower classification.

The criteria EPA intends to use to evaluate whether it is appropriate to reclassify a particular area include:

Request by state:The EPA does not intend to exercise its authority to reclassify areas on the EPA's own initiative. Rather, the EPA intends to rely on the state to submit a request for a reclassification. A tribe may also submit such a request and, in the case of a multi-state nonattainment area, all affected states must submit the same reclassification request.

Discontinuity:A five percent reclassification must not result in an illogical or excessive discontinuity relative to surrounding areas. In particular, in light of the area-wide nature of ozone formation, a reclassification should not create a "donut hole" where an area of one classification is surrounded by areas of higher classification.

Attainment:Evidence should be available that the proposed area would be able to attain by the earlier date specified by the lower classification in the case of a reclassification downward.

Emissionsreductions: Evidence should be available that the area would be very likely to achieve the appropriate total percent emission reduction necessary in order to attain in the shorter time period for a reclassification downward. Trends:Near- and long-term trends in emissions and air quality should support a reclassification. Historical air quality data should indicate substantial air quality improvement for a reclassification downward. Growth projections and emission trends should support a reclassification downward. In addition, we will consider whether vehicle miles traveled and other indicators of emissions are increasing at higher than normal rates. Years ofdata:The same years of ozone air quality data used for the initial designation and classification should be used for reclassification requests. A. Five Percent Reclassificationsto a Lower Classification

For an area to be eligible to be reclassified to a lower classification under section 181(a)(4), the area's design value must be within five percent of the upper limit for the next lower classification. For example, an area with a Moderate design value of 0.090 ppm (or less) would be eligible to request a reclassification to Marginal because 0.090 ppm is five percent more than the upper limit of 0.086 ppm for the Marginal classification. Accordingly, areas with the following design values may be eligible to request a reclassification to the next lower classification: Moderate areas with a design value of 0.090 ppm or less; Serious areas with a design value of 0.105 ppm or less; and Severe areas with a design value of 0.118 ppm or less. B. Five Percent Reclassificationsto a HigherClassification

An ozone nonattainment area may also be reclassified under section 181(a)(4) to the next higher classification. As with five percent reclassifications to a lower classification, the EPA does not intend to exercise its authority to reclassify areas to a higher classification on the EPA's own initiative. Rather, the EPA intends to rely on the state to submit a request for such a reclassification. Areas with the following design values are eligible to request a reclassification to the next higher classification: Marginal areas with a design value of 0.082 ppm or more; Moderate areas with a design value of 0.095 ppm or more; and Serious areas with a design value of 0.108 ppm or more. C. Timing ofthe FivePercent Reclassifications

A Governor or eligible Tribal governing body of any area that wishes to pursue a reclassification should submit all requests and supporting documentation to the EPA Regional Office by June 20, 2012. This relatively short time frame is necessary because section 181(a)(4) only authorizes the Administrator to make such 30092

### Federal Register/Vol. 77, No. 98/Monday, May 21, 2012/Rules and Regulations reclassifications within 90 days after the initial classification. XI. How do designations affect Indian country?

All state areas listed in the tables at the end of this document are designated as indicated, and include Indian country geographically located within such areas, except as otherwise noted. In general, state recommendations for initial area designations do not apply to Indian country. Consistent with the "Policy for Establishing Separate Air Quality Designations for Areas of Indian Country" (December 20, 2011), in instances where the EPA did not receive an initial designation recommendation from a tribe, the EPA is designating their area of Indian country along with the adjacent/surrounding state area(s). Tribes whose areas of Indian country are designated as nonattainment for the 2008 ozone NAAQS are being affected by poor air quality. Where nonattainment areas include both Indian country and state land, it is important for states and tribes to work together to coordinate planning efforts. Coordinated planning will help ensure that the planning decisions made by the states and tribes complement each other and that the nonattainment area makes reasonable progress toward attainment and ultimately attains the 2008 ozone NAAQS. XII. 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 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 the EPA's ozone designation Web site at http:// www.epa.gov/ozonedesignations.Statespecific information is available from the EPA Regional Offices. XIII. 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 Order12866:Regulatory PlanningandReview andExecutive Order13563: ImprovingRegulation and RegulatoryReview

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 (76 FR 3821, January 21, 2011). B. Paperwork ReductionAct 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 rule responds to the CAA 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.RegulatoryFlexibility 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 noticeand-comment rulemaking requirements under the Administrative Procedure Act (APA) or any other statute. This rule is not subject to notice-and-comment requirements as provided under CAA section 107(d)(2)(B). D. UnfundedMandatesReform 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 ozone NAAQS (40 CFR 50.15). The CAA establishes the process whereby states take primary responsibility in developing plans to meet the ozone NAAQS. 

### E.Executive Order13132: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 ofpower 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 ozone NAAQS. This rule will not modify the relationship of the states and the EPA for purposes of developing programs to implement the ozone NAAQS. Thus, Executive Order 13132 does not apply to this rule. F. Executive Order13175: Consultation and CoordinationWith Indian Tribal Governments

Subject to the Executive Order 13175 (65 FR 67249, November 9, 2000) the EPA may not issue a regulation that has tribal implications, that imposes substantial direct compliance costs, and that is not required by statute, unless the Federal government provides the funds necessary to pay the direct compliance costs incurred by tribal governments, or the EPA consults with tribal officials early in the process of developing the proposed regulation and develops a tribal summary impact statement.

The EPA has concluded that this action may have tribal implications. However, it will neither impose substantial direct compliance costs on tribal governments, nor preempt tribal law. Tribes whose areas of Indian country are being designated as "nonattainment" for the 2008 ozone NAAQS are affected by poor air quality. Although tribes are not required to submit implementation plans under the Clean Air Act, for those tribes whose areas are being designated as part of surrounding state areas, it will be imperative that states and the tribes coordinate on air quality planning efforts to ensure that ozone levels are reduced. In addition, several tribes' areas of Indian country are being designated as "nonattainment" separately from their surrounding state areas. For these tribes, internal capacity for air quality planning will be important to enable their areas of Indian country to come into attainment.

The EPA consulted with tribal officials early in the process of developing this regulation to permit them to have meaningful and timely input into its development. At the beginning of the designations process, 30093

### Federal Register/Vol. 77, No. 98/Monday, May 21, 2012/Rules and Regulations letters were sent to all tribes who were expected to be impacted by designations for the 2008 ozone NAAQS. These letters not only informed the tribes of the overall designations process, but also offered the tribes consultation to ensure early communication and coordination. Additionally, letters were sent to potentially affected tribes indicating the EPA's intended designations for their areas of Indian country. These letters offered an additional opportunity for consultation. All consultations were completed in late February/early April 2012. During consultation, the primary concerns raised by tribes included the following: Impact of nonattainment designation on future economic development; appropriateness ofusing data from monitors not on tribal land; and ensuring final decisions are consistent with the EPA's "Policy for Establishing Separate Air Quality Designations for Areas of Indian Country." (December 20, 2011). During the consultations, the EPA's Regional Offices ensured that the tribes fully understood the reasoning for the EPA's preliminary designations decisions and how those decisions are aligned with a consideration of the most recent certified air quality data and all other relevant information, including the EPA's "Policy for Establishing Separate Air Quality Designations for Areas of Indian Country." To the extent possible, the EPA included the tribes' input into the final decision-making process for designations of their areas of Indian country for the 2008 ozone NAAQS. G. Executive Order13045: Protectionof ChildrenFromEnvironmentalHealth andSafety 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 Order13211: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. L National Technology Transferand AdvancementAct (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 the Office of Management and Budget, 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 Order12898:Federal Actions To AddressEnvironmental Justicein MinorityPopulations 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 all areas where available information indicates a violation of the ozone 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 ReviewAct 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 July 20, 2012. L. JudicialReview

Section 307(b)(1) of the CAA indicates which Federal Courts of Appeal have venue for petitions ofreview 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 rule designating areas for the 2008 ozone NAAQS is "nationally applicable" within the meaning of section 307(b)(1). This rule establishes designations for areas across the U.S. for the 2008 ozone NAAQS. At the core of this rulemaking 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 

### 30094

### Federal Register/Vol. 77, No. 98/Monday, May 21, 2012/Rules and Regulations 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.

From this point, the boundary follows the center of the channel of the Green River generally to the south and east to the confluence of the Green River and the Big Sandy River (in R109W T22N Section 28). From this point, the boundary moves generally north and east along the centerline of the Big Sandy River to the confluence of the Big Sandy River with Little Sandy Creek (in R106W T25N Section 33). The boundary continues generally toward the northeast along the centerline of Little Sandy Creek to the confluence of Little Sandy Creek and Pacific Creek (in R106W T25N Section 24). From this point, the boundary moves generally to the east and north along the centerline of Pacific Creek to the confluence of Pacific Creek and Whitehorse Creek (in R103W T26N Section 10). From this point the boundary follows the centerline of Whitehorse Creek generally to the northeast until it reaches the eastern boundary of Section 1 R103W T26N. From the point where Whitehorse Creek crosses the eastern section line of Section 1 R103W T26N, the boundary moves straight north along the section line to the southeast corner of Section 36 R103W T27N in Sublette County where the boundary ends.

### II. Background

On March 27, 2008,1 the EPA 

### published revisions to both the primary

1See 73 FR 16436. The secondary ozone standard, designed to protect public welfare, was set at the same level and with the same averaging time as the primary standard. Since the primary and secondary standards are identical, we refer to them, both individually and together, as the "2008 ozone standard" (or, alternatively, the "2008 ozone NAAQS") throughout this preamble. For a detailed explanation of the calculation of the 3-year 8-hour average, see 40 CFR part 50, Appendix 1. 

### and secondary NAAQS for ozone to a level of 0.075 parts per million (ppm) (annual fourth-highest daily maximum 8-hour average concentration, averaged over 3 years). On July 16, 2009, the EPA announced that it would initiate a rulemaking to reconsider the NAAQS for various reasons, including the fact that the 0.075 ppm level fell outside of the range recommended by the Clean Air Scientific Advisory Committee. The EPA proposed reconsideration of the NAAQS on January 6, 2010. However, the EPA has not taken final action on the proposed reconsideration; thus, the current NAAQS for ozone remains at 0.075 ppm, as established in 2008. The 2008 ozone NAAQS retains the same general form and averaging time as the 0.08 ppm NAAQS set in 1997 but is set at a more protective level.

The EPA deferred initial designation of areas for the 2008 ozone NAAQS until March 12, 2011, pending the NAAQS reconsideration.2 See 75 FR 2936, January 19, 2010. After the March 12, 2011, designation deadline passed, WildEarth Guardians and Elizabeth Crowe (WildEarth Guardians) filed a lawsuit seeking to compel the EPA to take action to designate areas for the 2008 ozone NAAQS. WildEarth Guardians andElizabeth Crowe v. Jackson (D. Ariz. 11-CV-01661). The EPA and WildEarth Guardians settled the case by entering into a consent decree that requires the EPA Administrator to sign a final rule designating areas for the 2008 ozone NAAQS by May 31, 2012. In September 2011, the EPA reinitiated efforts 3 

### to designate areas for the 2008 ozone NAAQS, and notified states of the EPA's preliminary designation decisions on or about December 9, 2011. 4 

### On February 14, 2012, the EPA proposed this rulemaking to address the classifications and attainment deadlines that apply to the areas that are designated as nonattainment for the 2008 ozone NAAQS. See 77 FR 8197. The public comment period for this rule ran to March 15, 2012. The EPA received 41 comments on the Notice of Proposed Rulemaking. This document discusses the comments received and how they were considered by the EPA in general

2The 2008 ozone NAAQS were promulgated on March 12, 2008. The presumptive 2-year designation requirement found in CAA § 107(d)(1)(B) required designations for areas by March 12, 2010. The EPA invoked the additional year for designations as allowed under CAA § 107(d)(1)(B) because we determined that due to the reconsideration there was insufficient information to designate areas.

### terms. The Response to Comments document provides more detailed responses to the comments received. The public comments received on this rulemaking and the EPA's Response to Comments document are posted in the docket at www.regulations.gov.

We are taking four actions in this final rule: (1) Establishing the air quality thresholds that define each of the five Clean Air Act (CAA) classifications for areas designated nonattainment for the 2008 ozone NAAQS; (2) establishing the attainment deadline associated with each classification; (3) granting reclassification for selected nonattainment areas that voluntarily reclassified under the 1997 ozone NAAQS; and (4) revoking the 1997 ozone NAAQS for purposes of transportation conformity one year after the effective date of the designations for the 2008 ozone NAAQS.

First, we are establishing the air quality thresholds for classification categories that are assigned to all areas designated nonattainment for the 2008 ozone NAAQS according to the "percent-above-the-standard" methodology. In accordance with CAA section 181(a)(1), each area designated as nonattainment for the 2008 ozone NAAQS will be classified by operation of law at the same time as the area is designated by the EPA. Under subpart 2 of part D of title I of the CAA, state planning and emissions control requirements for ozone are determined, in part, by a nonattainment area's classification. In 1990, Congress amended part D of title I of the CAA by adding several new subparts, including subpart 2, which specifies implementation requirements for ozone nonattainment areas. For areas classified under subpart 2, these requirements apply in addition to the general State Implementation Plan (SIP) planning requirements applicable to all nonattainment areas under subpart 1 

### of part D. Under subpart 2, ozone nonattainment areas are classified based on the severity of their ozone levels (as determined based on the area's "design value." which represents air quality in the area for the most recent 3years). 5 

### The possible classifications are Marginal, Moderate, Serious, Severe, and Extreme. Nonattainment areas with a "lower" classification have ozone levels that are closer to the standard than areas with a "higher" classification.

5The air quality design value for the 8-hour ozone NAAQS is the 3-year average of the annual 4th highest daily maximum 8-hour average ozone concentration. See 40 CFR Part 50, Appendix 1. 

### 30161

### Federal Register/Vol. 77, No. 98/Monday, May 21, 2012/Rules and Regulations Areas in the lower classification levels have fewer and/or less stringent mandatory air quality planning and control requirements than those in higher classifications. For instance, among other things, for a Marginal area a state is required to adopt an emissions statement rule for stationary sources, submit a baseline emissions inventory, and implement a nonattainment area preconstruction permit program; however, states are not required to prepare an attainment demonstration and associated contingency measures for Marginal areas. For a Moderate area, a state needs to comply with the Marginal area requirements plus certain other requirements, including the requirement to submit a demonstration that the area will attain in 6 years, the requirement to adopt and implement certain emissions controls, such as reasonably available control technology, a basic vehicle inspection and maintenance program ifthe area meets the applicable population threshold, and provisions for greater emissions offsets for new or modified sources under the state's new source review (NSR) program. Each higher classification similarly requires emissions controls and stricter NSR offset requirements in addition to those required for the lower classifications. In addition, under the higher classifications, smaller sources are considered "major sources" for permitting and other requirements.

Second, the EPA is setting the attainment date as the number of years specified in Table 1 in section 181(a) from December 31, 2012. Because the attainment dates established in Table 1 have all passed and application of those dates would produce an absurd result, the EPA must reasonably interpret Table 1 to establish attainment dates for the 2008 ozone NAAQS. We believe the approach we are adopting is consistent with the intent of Congress at the time Table 1 was enacted as part of the CAA Amendments of 1990.

Third, the EPA is addressing situations where states have voluntarily requested reclassifications for areas under the 1997 ozone NAAQS. Six areas in California and one area in Texas were voluntarily reclassified at the request of the states for the 1997 ozone NAAQS. These areas have initial classifications for the 2008 ozone NAAQS under the percent-above-the-standard approach we are promulgating that are higher than their classifications under the 1997 NAAQS. In some cases, this would result in these areas being required to attain the more stringent 2008 ozone NAAQS prior to the deadline associated with the area's classification for the 1997 ozone NAAQS. The EPA proposed to interpret the voluntary reclassification requests for the 1997 ozone NAAQS for such areas to also apply for the more stringent 2008 ozone NAAQS unless the state were to expressly request otherwise. Texas requested that the voluntary reclassification for the 1997 NAAQS for the Houston area not apply for the 2008 NAAQS. California commented that it supports the approach of applying its requests for voluntary reclassification for the six areas for the 1997 NAAQS to the 2008 ozone NAAQS. The EPA is finalizing the voluntary reclassifications for the six California areas for the 2008 ozone NAAQS.

Fourth, in this rulemaking, the EPA is revoking the 1997 primary and secondary ozone NAAQS for transportation conformity purposes only.6 The revocation of the 1997 ozone NAAQS for this limited purpose will occur 1 year after the effective date of the initial area designation for each area for the 2008 ozone NAAQS. This approach results in only one ozone NAAQS-the more protective 2008 ozone NAAQS-applying for purposes of transportation conformity, after the end of the 1-year transportation conformity grace period that applies to newly designated nonattainment areas. See CAA section 176(c)(6). In the absence of this final action, areas currently in nonattainment or maintenance for the 1997 ozone NAAQS that are designated nonattainment for the 2008 ozone NAAQS would be required to implement the transportation conformity program for both the 1997 and 2008 ozone NAAQS concurrently. The EPA intends to address potential revocation of the 1997 ozone NAAQS for all other purposes in a future, separate rulemaking. III. What are the final classification thresholds for nonattainment areas for the 2008 ozone NAAQS? A. Summary ofProposedClassification Thresholds

The subpart 2 classification table in CAA section 181(a)(1) is based on 1-hour ozone nonattainment area design values (DVs) (i.e., beginning at a level of 0.121 ppm) because it was designed for implementation of the 0.12 ppm 1-hour standard, which was the effective ozone standard when Congress added the table to the CAA in 1990. Because the table

6 When the EPA revises a NAAQS, the prior NAAQS is not automatically revoked. Accordingly, both the 1997 ozone NAAQS and the more stringent 2008 ozone NAAQS are active standards unless and until the EPA takes action to revoke the previous 1997 standard. 

### is based on DVs for a 0.12 ppm 1-hour standard, the EPA recognized that it did not make sense to apply the thresholds listed in the table for implementing an 8-hour form of the ozone standard, first established in 1997. See 69 FR at 23998. We adopted by regulation a modified version of the subpart 2 classification table for the 1997 8-hour ozone standard which contains 8-hour DV thresholds for each classification, rather than the statutory 1-hour DV thresholds. 40 CFR 51.903(a). We translated the classification thresholds in the subpart 2 classification table from 1-hour DVs to 8-hour DVs based on the percentage by which each classification threshold in the table exceeds the 1-hour ozone NAAQS. We noted that these percentages, as established by Congress in 1990, set the classification thresholds at certain percentages or fractions above the level of the standard. 7 

### See 69 FR at 23957. We refer to this method as the "percent-above-the-standard" method. We proposed to take the same approach for the 2008 ozone NAAQS. After analyzing various alternative options, we proposed to use the same "percentabove-the-standard" methodology as was used for the 1997 ozone NAAQS 8 modified to account for the new level of 0.075 ppm as compared to the level of 0.08 ppm used to establish the classification table for the 1997 ozone NAAQS. See 77 FR at 8201-02.

The proposed percent-above-thestandard method is a simple and straightforward method for establishing classification thresholds that is based on principles inherent in the subpart 2 classification table itself. The principles include the following:

* Areas are grouped by the severity of their air quality problem as characterized by the degree of nonattainment based on their DV.

* Classification would occur "by operation of law" without relying on the EPA exercising discretion for individual situations (prior to any application of the 5 percent adjustment provision under section 181(a)(4) which may occur in the 90-day period following initial designations and classifications). See section III.C of this rule for additional details on how the EPA intends to address previous requests for

7 The upper thresholds of the Marginal, Moderate, Serious, and Severe classifications are precise percentages or fractions above the level of the standard, namely 15 percent (3/20ths more than the standard), 33.33 percent (one-third more than the standard), 50 percent (one-half more than the standard), and 133.3 percent (one and one-third more than the standard).

* Classification thresholds are derived using the same percentages above the standard that Congress used when promulgating Table 1 in section 181(a) for purposes of the 1-hour ozone standard, and reflect reasonable attainment periods for most areas that fall into the various classifications. B. BriefSummary of Comments on the Proposed Rule The EPA received several comments on the percent-above-the-standard methodology. Most of the commenters supported the adoption of this approach, stating that it was consistent with the CAA as well as the methodology used in the implementation of the 1997 ozone NAAQS. Those opposing this option did so for a number of reasons, including concerns that: It puts too many areas in the "Marginal" category; the outcome of the approach does not properly address the role of transport in the ability of downwind nonattainment areas to attain by the Marginal or Moderate attainment date; and a delay in progress will result from Marginal areas not attaining by the specified date in 2015.

Other commenters that did not directly support or oppose the use of the percent-above-the-standard methodology suggested that the EPA should have considered other options such as the use of subpart 1 for classifying areas. These comments, and the EPA's responses, are discussed in more detail in the Response to Comments document in the docket. C. FinalClassificationThresholds

In this section, we describe the EPA's methodology for establishing final classification thresholds for purposes of classifying ozone nonattainment areas with respect to the 2008 ozone NAAQS as well as the basis for the decision. After considering the comments, the EPA is finalizing the percent-above-thestandard methodology as proposed. Using this approach for the 2008 ozone NAAQS, the classification thresholds listed for the 1-hour NAAQS in the subpart 2 classification table are translated into a corresponding set of thresholds for the 2008 8-hour NAAQS by setting threshold DVs in the new table at the same percentages above the 2008 ozone NAAQS as the DV levels in the subpart 2 classification table are above the 1-hour ozone NAAQS. For example, the threshold separating the Marginal and Moderate classifications in the subpart 2 classification table (0.138 ppm) is 15 percent above the 1- hour ozone NAAQS (0.12 ppm). Thus, under this approach, the threshold separating the Marginal and Moderate classifications for the 2008 ozone NAAQS is 0.075 ppm plus 15 percent, or 0.086 ppm. Table 1, below, depicts this translation for all classifications as they apply for the 2008 ozone NAAQS. TABLE 1-SUBPART

Several areas, including the Chicago area, certified their 2011 air quality data early, which allowed the EPA to consider that data for purposes of final designations. This table includes the Chicago nonattainment area in the total number of areas.



### The EPA is finalizing this approach because the percent-above-the-standard methodology reflects the same approach codified in the CAA, as amended in 1990. It also results in the majority of areas receiving a classification with an attainment date that we believe the areas can meet. The EPA performed an analysis that indicates that the majority of areas classified as Marginal will be able to attain the 2008 ozone NAAQS within 3years of designation (i.e., in 2015) due to reductions of ozone precursors resulting from a number of federal and state emission reduction programs that have already been adopted. 1 0 

### Such programs include more stringent emission standards for onroad and nonroad vehicles and equipment (with associated fleet turnover), and regional reductions in power plant emissions to address interstate transport." For areas classified Moderate and above that are required to develop attainment demonstrations and adopt reasonably available control measures, it is unlikely that already adopted federal and existing state measures will be sufficient to bring the areas into attainment. The EPA did not attempt to forecast additional federal, regional, state or local control measures that may be implemented prior to the relevant attainment dates in 2018 that might help these areas attain the NAAQS. However, we note that the federal and regional programs already in place, in conjunction with others that may be adopted in the next several years, such as maximum achievable control technology standards for boilers, will help these areas make progress toward attainment. In addition, the CAA requires these areas to meet reasonable progress goals out to their attainment date and also requires these areas to evaluate what reasonably available control measures are available in order

### to attain as expeditiously as practicable. For these reasons, we anticipate that these areas will be able to attain the 2008 ozone NAAQS by the attainment date for their classification. We note, as provided further below, several areas with the most persistent ozone problems are most likely not to attain by the attainment date associated with their classification by operation of law, and are being voluntarily reclassified to a higher classification in this final rule. IV. How will areas that were voluntarily reclassified under the 1997 ozone NAAQS be addressed? A. Summary ofProposed ReclassificationofSelectedAreas

CAA section 181(b)(3) provides that a state may voluntarily request that the EPA reclassify a nonattainment area within the state to a higher classification. The EPA has no discretion to deny such requests. Once an area is reclassified to a higher classification, it becomes subject to the associated additional planning and control requirements for that higher classification as well and must attain the standard no later than the later maximum attainment date for that classification.

There are seven areas for which states requested a voluntary reclassification with respect to the 1997 ozone NAAQS. The EPA has granted voluntary reclassification requests for six of these areas, and is in the process of completing the request for one area.' 2 

### These areas are initially classified for the 2008 ozone NAAQS with a lower classification than the areas have for the 1997 ozone NAAQS. Moreover, the maximum attainment date for the 2008

12 Ventura County, CA was reclassified from Moderate to Serious (Approved 05/20/2008, 73 FR Page 29073, Effective: 06/19/2008). HoustonGalveston-Brazoria, TX was reclassified from Moderate to Severe-15 (Approved 10/01/2008, 73 FR Page 56983, Effective: 10/31/2008). Reclassification of the Los Angeles-South Coast, San Joaquin Valley, Riverside County, and Sacramento Metro areas (May 5, 2010, 75 FR 24409) became effective June 4, 2010. The EPA is in the process of approving the requested voluntary reclassification of West Mojave Desert, CA from Moderate to Severe. 

### ozone NAAQS based on that lower classification would be before the maximum attainment date for the area for the less stringent 1997 ozone NAAQS. The EPA proposed to interpret the voluntary reclassification requests for the 1997 ozone NAAQS for such areas also to apply for the more stringent 2008 ozone NAAQS unless the state were to expressly request otherwise. Based on discussions with affected areas, we believed it was reasonable to expect that in most instances, where a state requested a voluntary reclassification under the less stringent 1997 ozone NAAQS, it would make the same request for the 2008 ozone NAAQS. The EPA proposed this approach in order to minimize burden on states and to address the concern that some areas might have an earlier attainment date for the more stringent 2008 ozone standard. Moreover, this approach would obviate the need to process separate voluntary reclassification requests for the 2008 NAAQS which might have the effect of delaying certain actions while an area's classification was being modified. B. BriefSummary of Comments Received

The EPA received several comments on the application of the voluntary reclassification requests for the 1997 ozone NAAQS to the more stringent 2008 ozone NAAQS. Supporters of the proposal included the affected state and local air quality management agencies in California. Almost all of the commenters supporting this approach indicated that an area that needed to request more time to attain the 1997 ozone NAAQS would likely need additional time to meet the more stringent 2008 ozone NAAQS. The State of Texas indicated that it did not want the voluntary reclassification request for the Houston area for the 1997 ozone NAAQS to be interpreted to also apply for the 2008 ozone NAAQS. One commenter questioned the authority of the EPA to apply the reclassification request for an area under the 1997 ozone NAAQS to the area's classification 30164

### Federal Register/Vol. 77, No. 98/Monday, May 21, 2012/Rules and Regulations under the 2008 ozone NAAQS. These comments, and the EPA's responses, are discussed in more detail in the Response to Comments document in the docket. C. Final Action Once the initial area designations and classifications for the 2008 ozone NAAQS are completed, the CAA provides three mechanisms for addressing nonattainment areas that may not be attaining or are not able to attain by the attainment date provided for their classification. First, section 181(a)(4) provides that within 90 days of the effective date of designation and classification, the Administrator may exercise discretion to reclassify an area to a higher classification ifits DV is within 5 percent of the DV range of the higher classification. 1 3 

### Any state interested in taking advantage of this flexibility should submit a request to the EPA in sufficient time for the Administrator to make a determination within the 90 days provided.

The second mechanism, as provided in section 181(b)(3), allows a state to voluntarily request at any time that the EPA reclassify the area to a higher classification. The EPA has no discretion to deny such requests. Once an area is reclassified to a higher classification, it becomes subject to the associated additional planning and control requirements for that higher classification and must attain the standard no later than the later maximum attainment date for that classification. Any state may request a voluntary reclassification under the 2008 ozone NAAQS at any time prior to the area's attainment deadline.

The third mechanism, as provided in section 181(b)(2), requires that an area be reclassified to the next higher classification (i.e., "bumped-up") if the EPA determines that the area has failed to attain the standard by the area's attainment date and does not qualify for a 1-year attainment date extension as allowed under CAA section 181(b)(2). 1 4 

### Areas classified as Severe are not reclassified to Extreme, as provided under CAA section 181(b)(2)(A), but instead are subject to other requirements as provided in section 181(b)(4).

The areas for which states requested a voluntary reclassification would initially have been classified with a lower classification with an earlier maximum attainment date for the more stringent 2008 NAAQS than the area had for the 1997 NAAQS. At the time the EPA issued the proposed rule, we believed it likely that these areas would as a result have requested a similar reclassification for the 2008 NAAQS. The EPA is obligated to approve such voluntary reclassification requests if made. During the comment period, the State of California confirmed that it wished for the EPA to interpret its voluntary reclassification requests for areas within the state for the 1997 ozone NAAQS to also apply for the 2008 ozone NAAQS. The State of Texas indicated that it did not wish for the EPA to interpret its reclassification request for the 1997 ozone NAAQS for the Houston area as applying to the 2008 NAAQS. Therefore, we are treating the prior requests made for the nonattainment areas in California listed in Table 3 as requests that also apply to the 2008 ozone NAAQS. This final rule reduces the burden on the State of California and the affected air management districts by obviating the need to go through a separate process to request bump-up for the 2008 NAAQS.

### V. What are the attainment deadlines for each classification? A. Summary ofProposed Attainment Deadlines

The CAA provides that the primary NAAQS attainment dates for areas subject to subpart 2 must be as expeditious as practicable but no later than the deadlines provided in the subpart 2 classification table in CAA section 181(a)(1). The deadlines for attainment in the subpart 2 classification table are specified in terms of a certain number of years from the date of enactment of the 1990 Amendments to the CAA (i.e.,

13This CAA provision also provides the same authority for reclassifying areas to a lower classification. Since the vast majority of nonattainment areas for the 2008 NAAQS are classified Marginal, very few areas are eligible to request a reclassification to a lower classification. We anticipate that no states will request a 

### November 15, 1990). For instance, the attainment date for Moderate areas is expressed as "6 years after November 15, 1990." Because these time periods are clearly inappropriate for a new ozone standard promulgated in 2008, we proposed to interpret the attainment deadlines in the subpart 2 classification table as they would apply to the 2008 ozone NAAQS.

The EPA proposed two options for establishing the maximum attainment dates for areas in each nonattainment classification. Under the first option, the attainment dates would be the precise number of years specified in Table 1 with such time period running from the reclassification to a lower classification because our analyses indicate that these areas will need longer than 3years to attain the NAAQS and additional controls will be necessary for attainment.

14We note that for purposes of the 1997 ozone NAAQS, we promulgated a regulation interpreting CAA section 181(b)(4) for purposes of an 8-hour 

### effective date of designation. Under the second option, the attainment dates would be December 31 of the year that is the specified number of years in Table 1 after the effective date of designation.

The first option, which was the same approach we took for the 1997 ozone NAAQS, would interpret "year" in the subpart 2 classification table to mean consecutive 365-day periodsl 5 

### and we would substitute "after the effective date of designation" for the CAA's "after November 15, 1990" language in the subpart 2 classification table. Under this approach, the attainment deadline would fall a precise number of years after the effective date of designation.

ozone NAAQS. 40 CFR 51.907. We anticipate that we will propose a similar regulation for the 2008 ozone standard as part of the proposed implementation rule.

15

Except in the case of a leap year, where the year would be a rolling 366-day period. 

### 30165

### Federal Register/Vol. 77, No. 98/Monday, May 21, 2012/Rules and Regulations For the second option, the attainment date would be specified as a certain number of years from the end of the calendar year in which an area's nonattainment designation is effective (i.e., from December 31, 2012). The EPA explained in its proposal that where the designation is effective late in the ozone season, as we expected to be the case for the 2008 ozone NAAQS, the first option had the effect ofproviding one less complete ozone season for areas to improve their air quality than was accorded areas under the CAA as amended in 1990. We described that under the first option, a Marginal area effectively would have only two full ozone seasons following the effective date of designation to improve its air quality in order to attain by its attainment date. This is because attainment is based on three full ozone seasons of air quality data; thus in order to attain "by" its attainment date, the area could not consider air quality for an ozone season during which the attainment date falls.

We explained our belief that the second option is consistent with the time periods provided for attainment of the 1-hour ozone NAAQS at the time the CAA was amended. The CAA Amendments were enacted on November 15, 1990, after the end of the ozone season for virtually all areas, and for the few areas that had year-round ozone seasons, the EPA interpreted the Act to allow consideration of air quality in the attainment year even though the attainment date fell on November 15. Thus, when the CAA was amended in mid-November 1990, 1-hour Marginal areas had three full ozone seasons to achieve any reductions necessary for attainment, and Moderate areas had six full ozone seasons, because the attainment deadline was the anniversary of the enactment of the 1990 CAA (November 15). B. BriefSummary of Comments Received

The EPA received numerous comments on the attainment deadlines proposal. A few commenters supported the first option based on what they believed to be a plain reading of the CAA. A number of commenters opposed the first option, because it would not allow air quality data from the attainment year to be used in determining if the area attained the NAAQS by the deadline. Most of the commenters supported the adoption of the second option believing that it was most consistent with the 1990 CAA Amendments and that it would ensure that at least three full ozone seasons of data following designation (2013-2015) would be used for Marginal areas (and six (2013-2018) for Moderate areas, etc.) to determine attainment with the 2008 ozone NAAQS. Those opposing the second option indicated it would result in further delays in implementing controls in areas required to attain the 2008 ozone NAAQS, and that it arbitrarily endangers human health. These comments, and the EPA's responses, are discussed in more detail in the Response to Comments document in the docket. C. Final Action The EPA is finalizing the second proposed option. Attainment deadlines for the 2008 ozone NAAQS nonattainment areas will be December 31 of the calendar year that is the number of years specified for each classification in Table 1 with the number of years running from 2012. The EPA believes that this approach is appropriate for several reasons. First, we believe it is consistent with the intent of Congress at the time the CAA Amendments of 1990 were enacted. Since ozone seasons for most areas run during the spring, summer and fall, 1 6 

### the CAA, as amended in 1990, allowed Marginal areas three full ozone seasons to attain and maintain the NAAQS (and six full ozone seasons for Moderate areas, etc.) after the time that areas were designated and classified by operation of law at the time of enactment of the CAA Amendments. If the attainment date runs from the effective date of designation (i.e., mid-2012), to the extent measures beyond federal measures or state measures that are already in place would be needed for attainment of the 2008 ozone NAAQS by Marginal areas, states would have 18 to 21 months 17 

### to adopt and implement

16 A few of the most southern areas in the country do have a year-round ozone season. For purposes of the 1-hour NAAQS, the EPA effectively interpreted the November 15 attainment date as the end of the calendar year (i.e., the end of calendar years 1993, 1996, 1999, 2005, 2007 and 2010).

17 The ozone season for all areas of California, Nevada, Arizona, Southern Texas and Southern Louisiana starts in January, which would provide 18 months for areas classified as Marginal in such 

### such measures no later than the beginning of the 2014 ozone season. This is less time than such areas had for purposes of the 1-hour ozone standard under the CAA as amended in 1990. At that time, states with Marginal areas had over two years to adopt and implement such measures prior to the final ozone season used for purposes of determining attainment.' 8 

### In addition, this approach is consistent with the regulatory provisions specifying how to determine whether an area has attained the 2008 ozone NAAQS, which require an evaluation of monitoring data from 3 consecutive calendar years running from January 1 

### to December 31 of each year.

Accordingly, areas initially classified as Marginal are required to attain the 2008 ozone NAAQS no later than December 31, 2015, and the EPA will evaluate whether the area attained the NAAQS based on monitored ozone data from 2013-2015. Areas initially classified as Moderate are required to attain the 2008 ozone NAAQS no later than December 31, 2018, and the EPA will evaluate whether the area attained the NAAQS based on monitored ozone data from 2016-2018. Serious, Severe, and Extreme areas are required to attain the 2008 ozone NAAQS by December 31, 2021, 2027 and 2032, respectively. Table 4 summarizes the final attainment deadlines for all classification categories.
states to adopt and implement any additional measures needed for attainment. The ozone season for all areas of Colorado, Northern Texas, Northern Louisiana, Alabama, Mississippi, Georgia, Florida, Tennessee and Kentucky starts in March, which would provide 20 months for areas classified as Marginal in such states to adopt and implement any additional measures needed for attainment. The ozone season for all other areas designated nonattainment for the 2008 NAAQS begins in April, which would provide 21 months for areas classified as Marginal in such states to adopt and implement any additional measures needed for attainment.

18The same is true for the higher classifications if the attainment date falls in the middle of the year. For example, under Option 1,Moderate areas would have approximately 41%z years to adopt and implement measures necessary to attain the 2008 ozone NAAQS (i.e., no later than the beginning of the 2016 ozone season, which would be the final ozone season relied on for attainment), whereas at the time of the CAA Amendments of 1990, Moderate areas had approximately 5 years to adopt and implement measures prior to the beginning of the 1996 ozone season, which was the final ozone season considered for determining whether an area attained by the November 1996 Moderate area attainment date.

### VI. When is the EPA revoking the 1997 ozone NAAQS for transportation conformity purposes? A. Summary ofProposal

Transportation conformity is required under CAA section 176(c) to ensure that transportation plans, transportation improvement programs (TIPs) and federally supported highway and transit projects are consistent with ("conform to") the purpose of the SIP. Conformity to the purpose of the SIP means that transportation activities will not cause new air quality violations, worsen existing violations, or delay timely attainment of the relevant NAAQS or interim reductions and milestones. The EPA's Transportation Conformity Rule (40 CFR 51.390 and Part 93, subpart A) establishes the criteria and procedures for determining whether transportation activities conform to the SIP.

The EPA proposed to revoke the 1997 ozone NAAQS one year after the effective date of designations for the 2008 ozone NAAQS for transportation conformity purposes only. As the EPA described in the proposal, revoking the 1997 ozone NAAQS for transportation conformity purposes would bring certainty to the transportation planning process in ozone nonattainment and maintenance areas. It would also ensure that backsliding does not occur for purposes of transportation conformity as areas designated nonattainment for the 2008 ozone NAAQS will be required to use adequate or approved SIP motor vehicle emissions budgets for the 1997 ozone NAAQS or 1-hour ozone NAAQS, if the area has such SIP budgets for one of these ozone NAAQS, until SIP budgets are found adequate or are approved for the 2008 ozone NAAQS as required by recent court decisions discussed below and as required by CAA 176(c)(1) and by the transportation conformity rule (40 CFR 93.109(c)(2)). 1 9 ,20 

### Specifically, CAA

19

A motor vehicle emissions budget is that portion of the total allowable emissions defined in the submitted or approved control strategy implementation plan revision or maintenance plan for a certain date for the purpose of meeting reasonable further progress milestones or demonstrating attainment or maintenance of the 

### section 176(c)(1) states, in part, "No metropolitan planning organization designated under section 134 of Title 23 shall give its approval to any project, program, or plan which does not conform to an implementation plan approved or promulgated under section 7410 of this title." Under the EPA's regulations (40 CFR 93.109(c)(2)), adequate or approved motor vehicle emissions budgets for a prior NAAQS must be used in transportation conformity determinations for a revised NAAQS until such time that budgets for the revised NAAQS are either found adequate or are approved. The EPA is finalizing this limited revocation of the 1997 ozone NAAQS at this time to provide certainty to the transportation planning process. In a subsequent rulemaking the EPA will consider whether to also revoke the 1997 ozone NAAQS on the same timeline for all other purposes.

This approach was the same approach the EPA used to transition from the 1-hour ozone NAAQS to the more stringent 1997 ozone NAAQS. For that transition, our Phase 1 implementation rule for the 1997 ozone NAAQS revoked the 1-hour ozone NAAQS for all purposes one year after the effective date of the initial area designations for the 1997 ozone NAAQS. See 69 FR 23954. The Phase 1 rule also established comprehensive anti-backsliding provisions to ensure that requirements for the 1-hour ozone NAAQS would continue in place as areas transitioned to implementing the more stringent 1997 ozone NAAQS. NAAQS, for any criteria pollutant or its precursors, allocated to highway and transit vehicle use and emissions.

200n March 14, 2012, the EPA finalized a revision to the transportation conformity rule, which among other things revised the rule to specifically require that a nonattainment area that has approved or adequate motor vehicle emissions budgets in an applicable implementation plan or implementation plan submission for another NAAQS for the same pollutant must use those budgets in transportation conformity determinations until motor vehicle emissions budgets for the current NAAQS are submitted by the state and found adequate or are approved by the EPA. This revision to the conformity rule was effective on April 13, 2012. (77 FR 14979.) 

### The revocation of the 1-hour standard and the associated anti-backsliding provisions were the subject of litigation. In its December 2006 decision on that challenge, as modified following rehearing, the Court held with respect to the anti-backsliding approach for transportation conformity that 1-hour motor vehicle emissions budgets must be used where such budgets have been found adequate or approved, as part of 8-hour conformity determinations until 8-hour motor vehicle emissions budgets are available (South CoastAir Quality ManagementDistrictv. EPA, 472 F.3d at 882). In addition, the Court affirmed more broadly that in order for transportation conformity determinations to fulfill the requirements of CAA section 176(c)(1), motor vehicle emissions budgets for a prior NAAQS must be used in transportation conformity determinations under a revised NAAQS until emissions budgets for the revised NAAQS are either found adequate or are approved, but that conformity determinations need not be made for a revoked standard. Therefore, areas designated nonattainment for the 2008 ozone NAAQS that have adequate or approved SIP budgets for either the 1997 ozone NAAQS or the 1-hour ozone NAAQS must continue to use such budgets in transportation conformity determinations until budgets for the 2008 ozone NAAQS are found adequate or are approved.21

Similar to our rationale in the Phase 1 rule for implementation of the 1997 ozone NAAQS, we explained at proposal that we believe this approach makes the most sense because it would result in only one ozone NAAQS-the 2008 ozone NAAQS-applying for purposes of transportation conformity, after the end of the 1-year transportation conformity grace period that applies to newly designated nonattainment areas (CAA section 176(c)(6)). If the 1997

21 Areas without adequate or approved SIP budgets for either the 1997 ozone NAAQS or the 1-hour ozone NAAQS are required to demonstrate conformity using one or both of the interim emissions tests depending on their classification as required by 40 CFR 93.119. 

### 30167

### Federal Register/Vol. 77, No. 98/Monday, May 21, 2012/Rules and Regulations

ozone NAAQS were to remain in place after conformity applies for the 2008 ozone NAAQS, metropolitan planning organizations and other state, local, and federal transportation and air quality agencies in areas that are currently nonattainment or maintenance for the 1997 ozone NAAQS and will be designated nonattainment for the 2008 ozone NAAQS would be required to implement the transportation conformity program for both ozone NAAQS concurrently. This could lead to unnecessary complexity for conformity determinations, especially if an area's boundaries for the two ozone NAAQS differ from one another and the same test of conformity cannot be used for both ozone NAAQS. Even where an area's boundaries are unchanged, different analysis years under the conformity rules may be required for each ozone NAAQS. Furthermore, we believe that it is more important to determine conformity for the new 2008 ozone NAAQS that is more protective of health and welfare. Therefore, for transportation conformity purposes, this final rule provides a seamless transition from demonstrating conformity for the 1997 ozone NAAQS to demonstrating conformity for the 2008 ozone NAAQS. Revoking the 1997 ozone NAAQS one year after the effective date of designations for the limited purpose of transportation conformity would leave no gap in conformity's application in any 2008 ozone nonattainment area. B. Final Date forRevoking the 1997 Ozone NAAQS for Transportation ConformityPurposes

The EPA received many comments regarding the revocation of the 1997 ozone NAAQS for purposes of transportation conformity. Most of the commenters supported revoking the 1997 ozone NAAQS for transportation conformity purposes one year after the effective date of designations for the 2008 ozone NAAQS, as proposed, because this would minimize the burden on states, and focus efforts on the more stringent 2008 ozone NAAQS. Those opposing this option did so as a result of concerns about backsliding and the legality ofrevoking the 1997 ozone NAAQS at all. Several other comments were received that were directed at topics such as general conformity and revocation of the 1997 ozone NAAQS for other purposes that will be addressed in a subsequent rule addressing SIP requirements for the 2008 ozone NAAQS. These comments, and the EPA's responses, are discussed in more detail in the Response to Comments document in the docket. After considering the comments and for the reasons described above, the EPA is finalizing the proposed revocation.

This final rule does not revoke the 1997 ozone NAAQS for purposes other than transportation conformity. A subsequent proposal addressing SIP requirements for the 2008 ozone NAAQS will cover the broader antibacksliding requirements that might apply if the 1997 standard is revoked for purposes other than transportation conformity. VII. Statutory and Executive Order Reviews A. Executive Order12866:Regulatory PlanningandReview andExecutive Order13563: ImprovingRegulationand RegulatoryReview

This action is not a "significant regulatory action" under the terms of Executive Order 12866 (58 FR 51735, October 4, 1993) and is therefore not subject to review under Executive Orders 12866 and 13563 (76 FR 3821, January 21, 2011). B. Paperwork ReductionAct 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).

The final Classifications Rule for the 2008 ozone NAAQS establishes the air quality thresholds associated with each classification, which is assigned by operation of law at the time of designation as provided in section 181(a) of the CAA. It also reclassifies six areas in California to a higher classification, consistent with the State of California's previous request to reclassify such areas for the 1997 ozone NAAQS. This rule establishes the attainment date as December 31st of the year that is the number of years specified in Table 1 in CAA section 182(a) running from the year of designation (i.e., 2012). This rule also revokes the 1997 ozone NAAQS for transportation conformity purposes only. This limited revocation will bring certainty to the transportation conformity process consistent with prior court decisions and CAA section 176(c). This rule, in conjunction with another implementation rule we plan to propose in the future, will help states identify planning requirements that apply for purposes of attaining and maintaining the 2008 ozone NAAQS. No new information needs to be collected from the states as a result of this final rule. C.RegulatoryFlexibility Act The Regulatory Flexibility Act (RFA) generally requires an agency to prepare a regulatory flexibility analysis of any regulation subject to notice and comment rulemaking requirements under the Administrative Procedures Act or any other statute unless the agency certifies the rule will not have a significant economic impact on a substantial number of small entities. Small entities include small businesses, small organizations, and small governmental jurisdictions.

For purposes of assessing the impacts of these final rules on small entities, small entity is defined as: (1) A small business as defined in the Small Business Administration's (SBA) regulations at 13 CFR 121.201; (2) a small governmental jurisdiction that is a government of a city, county, town, school district or special district with a population of less than 50,000; and (3) a small organization that is any notfor-profit enterprise which is independently owned and operated and is not dominant in its field.

The CAA requires the EPA to designate areas and provides for nonattainment areas to be classified by operation of law at the time of designation, and allows areas to request reclassification to a higher classification. This rule establishes the thresholds that define these initial classifications and reclassifies some areas, and also establishes the attainment deadline for each classification. The CAA also requires that nonattainment and maintenance areas make transportation conformity determinations. This rule revokes the 1997 ozone NAAQS one year after the effective date of designations so that areas designated nonattainment for the 2008 ozone NAAQS are required to address conformity requirements for only the more protective 2008 ozone NAAQS.

After considering the economic impacts of this final rule on small entities, the EPA certifies that this action will not have a significant economic impact on a substantial number of small entities. This final rule will not impose any requirements on small entities. D. UnfundedMandatesReform 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, and tribal governments, in the aggregate, or the private sector. This 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 section 202 and 205 of the UMRA. 30168

### Federal Register/Vol. 77, No. 98/Monday, May 21, 2012/Rules and Regulations This action is not subject to the requirements of section 203 of UMRA because it contains no regulatory requirements that might significantly or uniquely affect small governments. E.Executive Order13132: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 ofpower and responsibilities among the various levels of government, as specified in Executive Order 13132. The requirements to designate nonattainment areas, which are then classified by operation of law, as well as the requirement to grant reclassification requests are imposed by the CAA. Thus, Executive Order 13132 does not apply to these final regulations.

Although this action does not have federalism implications as defined in Executive Order 13132, the EPA recognizes that the adoption in 2008 of the more health-protective ozone standard has triggered CAA requirements for state agencies responsible for managing air quality programs. Under the CAA, achieving these health benefits requires the combined efforts of the federal, state, and local governments, each accomplishing the tasks for which they are best suited. In the spirit of Executive Order 13132 and consistent with the EPA policy to promote communications between the EPA and state and local governments, the EPA solicited comments on the proposal to this final rule from state and local officials. F. Executive Order13175: Consultation and CoordinationWith Indian Tribal Governments

This action does not have tribal implications, as specified in Executive Order 13175 (65 FR 67249, November 9, 2000). The final rules do not have a substantial direct effect on one or more Indian tribes under these regulatory revisions, and does not significantly or uniquely affect the communities of Indian tribal governments. Furthermore, these final regulatory revisions do not affect the relationship or distribution of power and responsibilities between the federal government and Indian tribes. The CAA and the Tribal Air Rule establish the relationship of the federal government and tribes in developing plans to attain the NAAQS, and these revisions to the regulations do nothing to modify that relationship. These proposed regulatory revisions do not have tribal implications. Thus, Executive Order 13175 does not apply to this action.

The EPA solicited comment on the proposal for this final action from tribal officials. G. Executive Order13045: Protectionof ChildrenFromEnvironmentalHealth 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 Order13211:Actions Concerning Regulations 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. L National Technology Transferand Advancement Act Section 12(d) of the National Technology Transfer Advancement Act of 1995 (NTTAA), Public Law 104-113, section 12(d) (15 U.S.C. 272 note) directs the EPA to use voluntary consensus standards in its regulatory activities unless to do so would be inconsistent with applicable law or otherwise impractical. The voluntary consensus standards are technical standards (e.g., materials specifications, test methods, sampling procedures, and business practices) that are developed or adopted by voluntary consensus standards bodies. NTTAA directs the EPA to provide Congress, through OMB, explanations when the agency decides not to use available and applicable voluntary consensus standards.

These final revisions to the regulations do not involve technical standards. Therefore, the EPA did not consider the use of any voluntary consensus standards. J. Executive Order12898:Federal Actions To AddressEnvironmental Justicein MinorityPopulations 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 United States.

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 does not affect the level of protection provided to human health or the environment. The final regulations establish classification thresholds and attainment deadlines for designated nonattainment areas for the 2008 ozone NAAQS, which are designed to protect all segments of the general populations. As such, they do not adversely affect the health or safety of minority or lowincome populations and are designed to protect and enhance the health and safety of these and other populations. Today's action also revokes the 1997 ozone NAAQS for transportation conformity purposes only. Such a revocation would not lead to disproportionately high and adverse human health or environmental effects on minority or low-income populations as the CAA requires transportation conformity to apply in any area that is designated nonattainment or maintenance by the EPA. This final rule ensures that transportation conformity is demonstrated in all areas that are designated nonattainment for the more protective 2008 ozone NAAQS. K. Congressional ReviewAct 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 United States. 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 United States 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 60 day s after publication in the Federal Register.
