**ACTION :**  Direct final rule.

**SUMMARY :**  EPA is making several determinations relating to 1997 8-hour ozone nonattainment areas in California. First, EPA is determining that six 8-hour ozone nonattainment areas in California (Amador and Calaveras Counties, Chico, Kern County, Mariposa and Tuolumne Counties, Nevada County, and Sutter County) (‘‘six CA areas’’) attained the 1997 8-hour ozone national ambient air quality standard (NAAQS) by their applicable attainment dates. Second, in making these determinations for Mariposa and Tuolumne Counties and Nevada County, EPA is also granting them one-year attainment date extensions. Lastly, EPA is determining that the six CA areas and the Ventura County 8-hour ozone nonattainment area in CA have attained and continue to attain the 1997 8-hour ozone NAAQS based on the most recent three years of data. Under the provisions of EPA’s ozone implementation rule, these determinations suspend the requirements for these areas to submit revisions to the state implementation plan related to attainment of the 1997 8- hour ozone standard for as long as these areas continue to meet the 1997 8-hour ozone NAAQS.

**DATES :**  These actions are effective on November 13, 2012 without further notice, unless EPA receives adverse comment by October 15, 2012. We are publishing these rules without prior proposal because the Agency views them as noncontroversial actions and anticipates no adverse comments.

1 Ventura County is classified as a ‘‘serious’’ nonattainment area for the 1997 8-hour ozone standard. As such, the applicable attainment date for Ventura County is June 15, 2013. 2 On May 20, 2008 (73 FR 29073), EPA granted California’s request to reclassify Ventura County from ‘‘moderate’’ to ‘‘serious’’ for the 8-hour ozone standard. As such, the applicable attainment date for Ventura County is June 15, 2013.

EPA is making several separate and independent types of determinations with respect to a number of 1997 8-hour ozone nonattainment areas in California. First, pursuant to section 181(b)(2) of the Clean Air Act (CAA), EPA is determining that the Amador and Calaveras Counties (Central Mountain Counties), Chico (Butte County), Kern County (Eastern Kern), Mariposa and Tuolumne Counties (Southern Mountain Counties), Nevada County (Western Nevada County), and Sutter County (Sutter Buttes) 8-hour ozone nonattainment areas in California (herein referred to as the ‘‘six CA areas’’) attained the 1997 8-hour ozone NAAQS by their respective applicable attainment dates. Second, in connection with this determination, EPA is also granting, pursuant to section 181(a)(5) and 40 CFR 51.907, applications submitted by the California Air Resources Board (CARB) for extensions to the applicable attainment dates for the Southern Mountain Counties and Western Nevada County nonattainment

areas.

The applicable attainment dates vary among the six CA areas. For Butte County and Sutter Buttes, EPA is determining that these areas attained the 1997 8-hour ozone standard by their applicable attainment deadline of June15, 2007, based on complete, qualityassured, and certified ambient air quality monitoring data for 2004–2006. For the Central Mountain Counties and Eastern Kern ozone nonattainment areas, EPA is determining that they attained the 1997 8-hour ozone standard by their applicable attainment deadline of June 15, 2010, based on complete, quality-assured and certified air quality data for 2007–2009. For the Southern Mountain Counties and Western Nevada County, whose original attainment date was June 15, 2010, EPA is granting a one-year attainment date extension until June 15, 2011 and determining that these areas attained the 1997 8-hour ozone NAAQS by that extended attainment date, based on complete, quality-assured data for 2008–2010. In addition, for all the areas listed above and for Ventura County, 1 EPA is determining, based on complete, quality-assured and certified air quality monitoring data for 2009–2011, that these areas have attained and continue to attain the 1997 8-hour ozone NAAQS. Preliminary data for 2012 indicate that these areas continue to attain the NAAQS. Under the provisions of 40 CFR 51.918, these latter determinations suspend the obligation of the State to submit certain planning requirements related to attainment for as long as the areas continue to attain the standard. II. What is the background for these actions?

A. Ozone NAAQS

In 1997, EPA revised the health-based NAAQS for ozone, setting it at 0.08 parts per million (ppm) averaged over an 8-hour time frame. EPA set the 8- hour ozone standard based on scientific evidence demonstrating that ozone causes adverse health effects at lower ozone concentrations and over longer periods of time than was understood when the pre-existing 1-hour ozone standard was set. EPA determined that the 8-hour standard would be more protective of human health, especially for children and adults who are activeoutdoors, and individuals with a preexisting respiratory disease, such as asthma.

On March 27, 2008 (73 FR 16436), EPA promulgated a revised 8-hour ozone NAAQS of 0.075 ppm. On April 30, 2012 (77 FR 30088 and 77 FR 30160), EPA issued final rules addressing air quality designations and implementation of the 2008 8-hour ozone NAAQS. The rulemakings that are the subject of this notice concern only the 1997 8-hour ozone NAAQS and are not affected by the 2008 8-hour ozone NAAQS. B. EPA Designations and Classifications of Ozone Nonattainment Areas

On April 30, 2004 (69 FR 23858), EPA finalized its attainment/nonattainment designations for areas across the country with respect to the 8-hour ozone standard. In that action EPA designated Butte County, the Central Mountain Counties, Eastern Kern, the Southern Mountain Counties, Sutter Buttes, and Western Nevada County as nonattainment under title I, part D, subpart 1 of the CAA (subpart 1) and provided that these designations would become effective on June 15, 2004. Also in EPA’s April 30, 2004 action, Ventura County was designated nonattainment under title I, part D, subpart 2 of the CAA (subpart 2) and classified as ‘‘moderate’’. 2

In June 2007, the United States Court of Appeals for the District of Columbia Circuit (D.C. Circuit Court) vacated the portion of the 1997 ozone implementation rule that allowed areas to be designated under subpart 1. 3 On January 16, 2009 (74 FR 2936), EPA published a proposed rule to address, among other issues, the D.C. Circuit Court vacatur of the classification system that EPA used to designate a subset of initial 1997 8-hour ozone nonattainment areas under subpart 1. In that rulemaking, EPA proposed that all areas designated nonattainment for the 1997 8-hour ozone NAAQS under subpart 1 would be classified as subpart 2 areas (hereafter referred to as the ‘‘Subpart 1/Subpart 2 1997 8-Hour Ozone Rulemaking’’). The Butte County, Central Mountain Counties, Eastern Kern, Southern Mountain Counties, Sutter Buttes, and Western Nevada County ozone nonattainment areas were among those areas that would be classified under subpart 2. On May 14, 2012 (77 FR 28424), EPA finalized the Subpart 1/Subpart 2 1997 8-Hour Ozone Rulemaking. The boundaries, resulting classifications and attainment dates for the six new subpart 2 California nonattainment areas and Ventura County are provided in Table 1.

C. One-Year Attainment Date Extensions

The 8-hour ozone implementation rule gives EPA discretion to grant up to two one-year extensions of the attainment date upon application by the state. The criteria for such a request are found in CAA section 181(a)(5) and 40 CFR 51.907. The state must show that (1) the state has complied with all requirements and commitments pertaining to the area in the applicable State Implementation Plan (SIP); and (2) no more than one exceedance of the NAAQS has occurred in the area in the year preceding the extension year. D. Determinations of Attainment by Areas’ Attainment Deadline and Determinations of Continued Attainment

5 On March 23, 2010, James Goldstene, Executive Officer of the California Air Resources Board, submitted a request for EPA to grant a one-year extension of the proposed attainment date for the Southern Mountain Counties area. The June 15, 2011 date reflects EPA’s final action today to grant CARB’s application for a one-year extension in the applicable attainment date for this area.

6 That portion of the Sutter Buttes mountain range at or above 2,000 feet in elevation.

7 That part of Ventura County excluding the Channel Islands of Anacapa and San Nicolas Islands.

8 That portion of Western Nevada County, which lies west of a line, described as follows: beginning at the Western Nevada Placer County boundary and running north along the western boundaries of Sections 24, 13, 12, 1, Township 17 North, Range 14 East, Mount Diablo Base and Meridian, and Sections 36, 25, 24, 13, 12, Township 18 North, Range 14 East to the Western Nevada Sierra County boundary.

9 On May 24, 2010, James Goldstene, Executive Officer of the California Air Resources Board, submitted a request for EPA to grant a one-year extension of the proposed attainment date for the Western Nevada County area. The June 15, 2011 date reflects EPA’s final action today to grant CARB’s application for a one-year extension in the applicable attainment date for this area. NAAQS ( see 40 CFR 51.918), if EPA issues a determination that an area is attaining the standard (through a rulemaking that includes public notice and comment), it will suspend the area’s obligations to submit an attainment demonstration and associated reasonable available control measures (RACM), a reasonable further progress (RFP) plan, contingency measures and other planning requirements related to attainment for as long as the area continues to attain. The determination of attainment is not equivalent to a redesignation. The state must still meet the statutory requirements for redesignation in order for an area to be redesignated to attainment. E. Ambient Air Quality Monitoring Data

A determination of whether an area’s air quality meets the ozone NAAQS is generally based upon the most recent three years of complete, quality-assured data gathered at established State and Local Air Monitoring Stations (SLAMS) in the nonattainment area and entered into the EPA Air Quality System (AQS) database. Data from air monitors operated by state/local agencies in compliance with EPA monitoring requirements must be submitted to AQS. Heads of monitoring agencies annually certify that these data are accurate to the best of their knowledge. Accordingly, EPA relies primarily on data in AQS when determining the attainment status of areas. See 40 CFR 50.10; 40 CFR part 50, appendix I; 40 CFR part 53; 40 CFR part 58, appendices A, C, D and E. All data are reviewed to determine the area’s air quality status in accordance with 40 CFR part 50, appendix I.

Under EPA regulations at 40 CFR part 50, the 1997 8-hour ozone standard is attained at a site when the 3-year average of the annual fourth-highest daily maximum 8-hour average ozone concentrations at an ozone monitor is less than or equal to 0.08 ppm. See 40 CFR 50.10. This 3-year average is referred to as the design value. When the design value is less than or equal to 0.084 ppm (based on the rounding convention in 40 CFR part 50, appendix I) at each monitoring site within the area, then the area is meeting the NAAQS. The data completeness requirement is met when the three-year average percent of days with valid ambient monitoring data is at least 90%, and no single year has less than 75% data completeness as determined in Appendix I of 40 CFR part 50.

A. Attainment Date Extensions

Pursuant to CAA section 181(a)(5) and 40 CFR 51.907, the State has requested, and EPA is approving one-year attainment date extensions for the Southern Mountain Counties and Western Nevada County nonattainment areas. The effect of granting the attainment date extensions is to allow the State an additional year to demonstrate that the Southern Mountain Counties and Western Nevada County nonattainment areas have attained the 1997 8-hour ozone NAAQS pursuant to section 181(b)(2) of the CAA. Without the one-year extension, the State cannot demonstrate that the two areas attained 1997 8-hour ozone NAAQS by the attainment dates in 77 FR 28424. B. Determinations of Attainment by Areas’ Applicable Attainment Dates

Pursuant to section 181(b)(2) of the CAA, EPA is determining that the Butte County, Central Mountain Counties, Eastern Kern, Southern Mountain Counties, Sutter Buttes, and Western Nevada County ozone nonattainment areas attained the 1997 8-hour ozone NAAQS by their applicable attainment dates.

These determinations discharge EPA’s obligations under section 181(b)(2) with respect to determining whether these areas attained by their respective attainment deadlines, and establish that these areas are not subject to reclassification for failure to attain by these deadlines.

C. Determinations of Current Attainment and 40 CFR 51.918

In addition, EPA is separately determining that the six CA areas and Ventura County have attained the standard based upon the most recent three years of data (without reference to their attainment deadlines). Under the provisions of 40 CFR 51.918, these determinations of attainment suspend the obligation for the State to submit certain planning requirements described above; however, they do not constitute redesignations to attainment under section 107(d)(3) of the CAA. The designation status of the six CA areas and Ventura County remains nonattainment for the 1997 8-hour ozone NAAQS until such time as EPA determines that each area meets the CAA requirements for redesignation to attainment, including an approved maintenance plan.

In accordance with 40 CFR 51.918, based on these determinations, the obligation under the CAA for the State of California to submit an attainment demonstration and RACM, RFP plan, contingency measures, and any other planning requirements related to attainment of the 1997 8-hour ozone NAAQS for these seven ozone nonattainment areas is suspended for so long as the areas continue to attain the 1997 8-hour ozone NAAQS. Although these requirements are suspended, EPA is not precluded from acting upon these elements, if California submits them for EPA review and approval.

The suspension continues until such time, if any, that EPA (i) redesignates the area to attainment at which time those requirements no longer apply, or (ii) subsequently determines that the area has violated the 1997 8-hour ozone NAAQS. It is separate from, and does not influence or otherwise affect, any future designation determination or requirements for the area based on any new or revised ozone NAAQS. It remains in effect regardless of whether EPA designates the area as a nonattainment area for purposes of any new or revised ozone NAAQS.

If EPA subsequently determines, after notice-and-comment rulemaking, that any one of these nonattainment areas has violated the 1997 8-hour ozone NAAQS, the basis for the suspension of the requirements for that area, provided by 40 CFR 51.918, would no longer exist, and the violating ozone nonattainment area would thereafter have to address those requirements. IV. What is EPA’s analysis of the relevant air quality data? A. Monitoring Network and Data Considerations

CARB is the governmental agency delegated under State law with the authority and responsibility for collecting ambient air quality data as directed by the CAA of 1977 and CAA Amendments of 1990. CARB and local Air Pollution Control Districts and Air Quality Management Districts (‘‘Districts’’) operate ambient monitoring stations throughout the State. CARB is the lead monitoring agency in the Primary Quality Assurance Organization 10 (PQAO) that includes all the monitoring agencies in the State with a few exceptions. 11 CARB, Butte County Air Pollution Control District (APCD), Northern Sierra Air Quality Management District (AQMD), and Ventura County APCD are the agencies responsible for monitoring ambient air quality within the seven nonattainment areas affected by today’s final action. In addition, CARB oversees the quality assurance of all data collected within the CARB PQAO. CARB submits annual monitoring network plans to EPA that describe the monitoring sites CARB operates, in addition to monitoring sites operated by many smaller air districts, including Butte County APCD and Northern Sierra AQMD. Ventura County APCD submits the annual monitoring network plan for all sites in Ventura County. These plans discuss the status of the air monitoring network, as required under 40 CFR part 58.10.

Since 2007, EPA has regularly reviewed these annual plans for compliance with the applicable reporting requirements in 40 CFR part 58. With respect to ozone, EPA has found that the areas’ network plans meet the applicable requirements under 40 CFR part 58. See EPA letters to CARB approving its annual network plans for years 2007, 2009, 2010, and 2011. 12 CARB did not propose modifications to their network in 2008 and therefore was not required to submit a network plan to EPA for approval. 13 EPA also concluded 14 from its Technical System Audit of the CARB PQAO (conducted during Summer 2007), that the combined ambient air monitoring network operated by CARB and the local air districts in their PQAO (which includes Butte County APCD, Northern Sierra AQMD, and Ventura County APCD) currently meets or exceeds the requirements for the minimum number of SLAMS for all criteria pollutants for the areas addressed in this action, and that all of the monitoring sites are reviewed with respect to monitoring objectives, spatial scales and other site criteria as required by 40 CFR part 58, appendix D. Also, CARB annually certifies that the data it submits to AQS are complete and quality-assured. This includes data from all CARB sites, along with some data for local district sites. 15 Northern Sierra AQMD annually certifies that the data it submits for its Grass Valley site to AQS are complete and quality-assured. 16 Ventura County APCD annually certifies that the data it submits for Ventura County to AQS are complete and quality-assured. 17 Data for

For most sites, the spatial scale and monitoring objectives are ‘‘regional’’ and ‘‘high concentrations.’’ 20 Consistent with the requirements contained in 40 CFR part 50, EPA has reviewed the complete, quality-assured, and certified 8-hour ozone ambient air monitoring data as recorded in AQS for the applicable monitoring period collected at the monitoring sites in the seven nonattainment areas. B. Evaluation of Attainment by Applicable Attainment Date and/or Current Attainment

Based on our review of the monitoring data, and taking into account the reliability of the ozone monitoring network in the relevant CA nonattainment areas and the reliability of the data collected by the network, EPA makes the determinations presented in the following paragraphs. 1. Butte County and Sutter Buttes

Table 2 shows the ozone design values for the Butte County and Sutter Buttes ozone nonattainment area monitors, based on ambient air quality monitoring data for the three-year period (2004–2006) prior to the applicable attainment date (June 15, 2007) and for the most recent three-year period (2009–2011). The data show that the design value for the 2004–2006 period was equal to or less than 0.084 ppm at all of the monitors. Therefore, pursuant to CAA section 181(b)(2), we are determining that the Butte County and Sutter Buttes marginal nonattainment areas attained the 1997 8-hour ozone NAAQS by their applicable attainment date of June 15,2007, based on complete, qualityassured data for the 2004–2006 ozone seasons. In addition, the data show that the design value for the 2009–2011 period was also equal to or less than 0.084 ppm at all of the monitors. Therefore, we are determining, based on the complete, quality-assured data for 2009–2011, that the Butte County and Sutter Buttes areas have attained the standard. Preliminary data available for 2012 indicate that the areas continue to attain the standard.

2. Eastern Kern and Central Mountain Counties

Table 3 shows the ozone design values for the Eastern Kern and Central Mountain Counties ozone nonattainment area monitors based on ambient air quality monitoring data for the three-year period (2007–2009) prior to the applicable attainment date (June 15, 2010) and the most recent three-year period (2009–2011). The data show that the design value for the 2007–2009 period was equal to or less than 0.084 ppm at all of the monitors. Therefore, pursuant to section 181(b)(2), we are determining that the Eastern Kern and Central Mountain Counties moderate nonattainment areas attained the 1997 8-hour ozone NAAQS by their applicable attainment deadline of June 15, 2010, based on the complete, quality-assured data for the 2007–2009 ozone seasons. In addition, the data show that the design value for the 2009– 2011 period was also equal to or less than 0.084 ppm at all of the monitors. Therefore, we are determining, based on the complete, quality-assured data for 2009–2011, that the Eastern Kern and Central Mountain Counties areas have attained the 1997 8-hour ozone standard. Preliminary data available for 2012 indicate that the areas continue to attain the standard.

3. Southern Mountain Counties and Western Nevada County

Table 4 shows the fourth-highest daily maximum recorded for 2009, the ozone design values for the Southern Mountain Counties and Western Nevada County nonattainment area monitors based on 2008–2010 ambient air quality monitoring data, and the ozone design values for the most recent three-year period (2009–2011). Because the Southern Mountain Counties and Western Nevada County are classified as ‘‘moderate’’ nonattainment areas, the applicable attainment date for both areas was set as June 15, 2010. However, the air quality and other factors in these areas showed the areas were eligible, pursuant to CAA section 181(a)(5) and 40 CFR 51.907, for extensions of the applicable attainment date for these two areas from June 15, 2010 to June 15, 2011. CARB applied to EPA for these extensions by letters dated March 23, 2010 and May 24, 2010 for Southern Mountain Counties and Western Nevada County, respectively (see also footnotes 5 and 9 in table 1 of this direct final rule).

As noted previously, under CAA section 181(a)(5) and 40 CFR 51.907, upon application of a State, EPA may extend for one additional year (‘‘extension year’’) the applicable attainment date if (1) the State has complied with all requirements and commitments pertaining to the area in the applicable State Implementation Plan (SIP); and (2) no more than one exceedance of the NAAQS has occurred in the area in the year preceding theextension year. No more than two oneyear extensions are allowed. We have reviewed the requests using the criteria set forth at CAA section 181(a)(5) and are approving the extensions in today’s action. The basis for our approval is set forth below.

First, the fourth-highest value recorded at the monitors in each of these areas did not exceed the NAAQS during 2009, the year preceding the extension year, thereby meeting one of the two criteria. Second, EPA interprets the requirement that the State is complying with the commitments and requirements in the applicable implementation plan, as referenced in section 181(a)(5) of the CAA, to meanthe State is implementing the EPAapproved SIP. 21 EPA has determined that the State is implementing the requirements in the EPA-approved SIP as applicable to these two nonattainment areas, thereby meeting the other criterion under section 181(a)(5). Therefore, because both criteria under CAA section 181(a)(5) are met in both areas, we are granting the one-year extensions for these two areas, and with the granting of one-year extensions under section 181(a)(5) for these areas, the applicable attainment date for the Southern Mountain Counties and Western Nevada County becomes June 15, 2011. With respect to this extended applicable attainment date, the data in table 4 show that the design value for the 2008–2010 period was equal to or less than 0.084 ppm at


### 56780 Federal Register / Vol. 77, No. 179 / Friday, September 14, 2012 / Rules and Regulations

22 As noted in footnote 1 in this document, Ventura County is classified as a ‘‘serious’’ nonattainment area for the 1997 8-hour ozone standard. As such, the applicable attainment date for Ventura County is June 15, 2013. all of the monitors. Therefore, pursuant to section 181(b)(2), we are determining that the Southern Mountain Counties and Western Nevada County moderate nonattainment areas attained the 1997 8-hour ozone NAAQS by their applicable attainment deadlines of June 15, 2011, based on the complete, quality-assured data for the 2008–2010 ozone seasons. In addition, the data show that the design value for the 2009– 2011 period was also equal to or less than 0.084 ppm at all of the monitors. Therefore, we are also determining, based on the most recent three years of complete, quality-assured data for 2009– 2011, that the Southern Mountain Counties and Western Nevada County areas have attained the standard. Preliminary data available for 2012 indicate that the areas continue to attain the standard.

V. EPA’s Final Actions

EPA is making three separate and independent types of determinations. First, pursuant to section 181(b)(2), EPA is determining that six 8-hour ozone nonattainment areas in California (Amador and Calaveras Counties, Chico, Kern County, Mariposa and Tuolumne Counties, Nevada County, and Sutter County) attained the 1997 8-hour ozone NAAQS by their respective applicable attainment dates based on complete, quality-assured, and certified ambient air quality monitoring data. Second, in making these determinations for two of these areas, Mariposa and Tuolumne Counties and Nevada County, EPA is also determining that these areas qualified for one-year attainment date extensions and granting these extensions under CAA section 181(a)(5) and 40 CFR 51.907. These extensions result in an applicable attainment deadline for these areas of June 15, 2011. As a result, EPA determines that that these two areas attained by their extended attainment dates. Third, EPA is separately determining that Amador and Calaveras Counties, Chico, Kern County, Mariposa and Tuolumne Counties, Nevada County, Sutter County, and Ventura County have each attained the 1997 8-hour ozone standard based on the most recent three years of complete, quality-assured, and certified data for 2009–2011. Preliminary data available for 2012 show that these areas continue to attain the standard. As provided in 40 CFR 51.918, these determinations of attainment suspend the requirements for the State of California to submit, for each of these seven ozone nonattainment areas, an attainment demonstration and associated RACM, RFP plan, contingency measures, and any other planning requirements related to attainment of the 1997 8-hour ozone NAAQS, for as long as the area continues to attain the 1997 8-hour ozone NAAQS.

We are publishing these rules without prior proposal because the Agency views them as noncontroversial actions and anticipates no adverse comments. However, in the proposed rules section of this Federal Register publication, EPA is publishing a separate document that will serve as the proposal should adverse comments be filed. These actions will be effective November 13, 2012, without further notice unless the EPA receives relevant adverse comments by October 15, 2012.

If we receive such comments, then we will publish a document withdrawing the final rule affected by the comments and informing the public that the rule will not take effect. All public comments received will then be addressed in a subsequent final rule based on the proposed rule. We will not institute a second comment period. Parties interested in commenting should do so at this time. If no such comments are received, the public is advised that this rule will be effective on November 13, 2012 and no further action will be taken on the proposed rule. VI. Statutory and Executive Order Reviews

These actions make determinations of attainment based on air quality, result in the suspension of certain federal requirements, grant attainment date extensions, and/or would not impose additional requirements beyond those imposed by state law. For that reason, these actions:

• Are not ‘‘significant regulatory actions’’ subject to review by the Office of Management and Budget under Executive Order 12866 (58 FR 51735, October 4, 1993);

• Do not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq. );

• Are certified as not having a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq. );

• Do not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104–4);

• Do not have Federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999); • Are not economically significant regulatory actions based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997);

• Are not significant regulatory actions subject to Executive Order 13211 (66 FR 28355, May 22, 2001);

• Are not subject to requirements of Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the CAA; and

• Do not provide EPA with the discretionary authority to address disproportionate human health or environmental effects with practical, appropriate, and legally permissible methods under Executive Order 12898 (59 FR 7629, February 16, 1994).

In addition, these actions do not have Tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), because the SIP obligations discussed herein do not apply to Indian Tribes and thus will not impose substantial direct costs on Tribal governments or preempt Tribal law.

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. EPA will submit a report containing this action and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the 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).

Under section 307(b)(1) of the CAA, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by November 13, 2012. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this action for the


### 56782 Federal Register / Vol. 77, No. 179 / Friday, September 14, 2012 / Rules and Regulations

purposes of judicial review nor does it extend the time within which a petition for judicial review may be filed, and shall not postpone the effectiveness of such rule or action. Parties with objections to this direct final rule are encouraged to file a comment in response to the parallel notice of proposed rulemaking for this action published in the proposed rules section of today’s Federal Register , rather than file an immediate petition for judicial review of this direct final rule, so that EPA can withdraw this direct final rule and address the comment in the proposed rulemaking. This action may not be challenged later in proceedings to enforce its requirements. ( See section 307(b)(2).) List of Subjects in 40 CFR Part 52

(e) Determinations of Attainment. Effective November 13, 2012.

(1) Approval of applications for extensions of applicable attainment dates. Under section 181(a)(5) of the Clean Air Act, EPA is approving the applications submitted by the California Air Resources Board dated March 23, 2010 and May 24, 2010 for extensions of the applicable attainment date for the Mariposa and Tuolumne Counties and Nevada County 8-hour ozone nonattainment areas, respectively, from June 15, 2010 to June 15, 2011.

(2) Determinations of attainment by the applicable attainment date. EPA has determined that the Amador and Calaveras Counties, Chico, Kern County, Mariposa and Tuolumne Counties, Nevada County, and Sutter County 8- hour ozone nonattainment areas in California attained the 1997 8-hour ozone national ambient air quality standard (NAAQS) by their applicable attainment dates. The applicable attainment dates are as follows: Amador and Calaveras Counties (June 15, 2010), Chico (June 15, 2007), Kern County (June 15, 2010), Mariposa and Tuolumne Counties (June 15, 2011), Nevada County (June 15, 2011), and Sutter County (June 15, 2007).

(3) Determination of attainment. EPA is determining that the Amador and Calaveras Counties, Chico, Kern County, Mariposa and Tuolumne Counties, Nevada County, Sutter County and Ventura County 8-hour ozone nonattainment areas have attained the 1997 8-hour ozone standard, based upon complete quality-assured data for 2009– 2011. Under the provisions of EPA’s ozone implementation rule (see 40 CFR 51.918), these determinations suspend the attainment demonstrations and associated reasonably available control measures, reasonable further progress plans, contingency measures, and other planning SIPs related to attainment for as long as the areas continue to attain the 1997 8-hour ozone standard. If EPA determines, after notice-and-comment rulemaking, that any of these areas no longer meets the 1997 ozone NAAQS, the corresponding determination of attainment for that area shall be withdrawn.
