**SUPPLEMENTARY INFORMATION :**  I. New Jersey’s Request for Attainment Date Extension for the Philadelphia Area

On June 23, 2010, the State of New Jersey requested a one-year attainment date extension for the Philadelphia Area. The Philadelphia Area, which is classified as moderate for the 1997 8-hour ozone National Ambient Air Quality Standards (NAAQS), consists of Cecil County in Maryland; Bucks, Chester, Delaware, Montgomery and Philadelphia Counties in Pennsylvania; the entire State of Delaware; and Atlantic, Burlington, Camden, Cape May, Cumberland, Gloucester, Mercer, Ocean, and Salem Counties in New Jersey. Since this area was classified as a moderate ozone nonattainment area, the statutory ozone attainment date, as prescribed by section 181(a) of the Clean Air Act (CAA), is June 15, 2010. New Jersey requested that the attainment date be extended to June 15, 2011. II. CAA Requirements and EPA Actions Regarding One-Year Extensions

Section 181(a)(5) of the CAA provides for a 1-year extension of the applicable attainment date for an ozone nonattainment area if the State has complied with the requirements in the applicable implementation plan and there is no more than one exceedance of the NAAQS in the year preceding the extension year. 40 CFR 51.907 sets forth how section 181(a)(5) applies to an area subject to the 1997 8-hour ozone NAAQS. Under 40 CFR 51.907, an area will meet the requirement of section 181(a)(5)(B) of the CAA pertaining to one-year extensions of the attainment date if:

(a) For the first 1-year extension, the area’s 4th highest daily 8-hour average in the attainment year is 0.084 parts per million (ppm) or less,

(b) For the second 1-year extension, the area’s 4th highest daily 8-hour value, averaged over both the original attainment year and the first extension year, is 0.084 ppm or less.

(c) For purposes of paragraphs (a) and (b) of this section, the area’s 4th highest daily 8-hour average shall be from the monitor with the highest 4th highest daily 8-hour average of all the monitors that represent that area.

EPA’s review of the actual ozone air quality data in the Air Quality System shows that the 4th highest daily average 8-hour ozone concentrations for the 2009 attainment year ozone season, for all monitors in the Philadelphia Area measured less than 0.084 ppm (Table 1), as required by 40 CFR 51.907(a). The highest-reading monitoring site had a 4th high value for 2009 of 0.074 ppm (Bucks/Pennsylvania). The monitoring data has been quality-controlled and quality-assured.

### 68735 Federal Register / Vol. 75, No. 216 / Tuesday, November 9, 2010 / Proposed Rules

EPA has determined that the requirements for a one-year extension of the attainment date have been fulfilled as follows:

(1) New Jersey has complied with all requirements and commitments pertaining to the area in the applicable ozone implementation plan. New Jersey’s applicable ozone implementation plan can be found at 40 CFR 52.1570. The most recent actions related to New Jersey’s applicable ozone implementation plan can be found at EPA’s rulemakings: ‘‘Approval and Promulgation of Implementation Plans; New Jersey Reasonable Further Progress Plans, Reasonably Available Control Technology, Reasonably Available Control Measures and Conformity Budgets ’’ proposed January 16, 2009 (74 FR 2945) and final rulemaking May 15, 2009 (74 FR 22837); ‘‘Approval and Promulgation of Implementation Plans; Implementation Plan Revision; State of New Jersey’’ proposed April 23, 2010 (75 FR 21197) and final rulemaking August 3, 2010 (74 FR 45483); and ‘‘Approval and Promulgation of Implementation Plans; New Jersey; 8-hour Ozone Control Measure ’’ proposed July 22, 2010 (75 FR 42672); and

(2) The maximum 4th highest daily 8-hour monitored value at any monitoring site in the Philadelphia area during the 2009 ozone season was 0.074 ppm, which is below the 0.084 ppm criteria.

Therefore, EPA is proposing to approve the State’s request for an extension of the attainment date for the New Jersey portion of the Philadelphia Area to June 15, 2011. If the approval is finalized, the table in 40 CFR 81.331 will be modified to reflect EPA’s approval of New Jersey’s attainment date extension request. The table is entitled ‘‘New Jersey-Ozone (8-Hour Standard). ’’

III. Conclusion

Pursuant to CAA section 181(a) and 40 CFR 51.907, EPA is proposing to approve an attainment date extension from June 15, 2010 to June 15, 2011 for the New Jersey portion of the Philadelphia Area, which is classified as moderate for the 1997 8-hour ozone NAAQS. EPA is publishing this rule as a proposal in the Proposed Rules section of this Federal Register , and receiving public comments until December 9,

2010. IV. Statutory and Executive Order Reviews

Under Executive Order 12866 (58 FR 51735, October 4, 1993), this action is

not a ‘‘ significant regulatory action’’ and therefore is not subject to review by the Office of Management and Budget. For this reason, this action is also not subject to Executive Order 13211,

‘‘Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use ’’ (66 FR 28355 (May 22, 2001)). This action determines, based on air quality considerations and compliance with the State implementation plan, that an area has qualified for a one-year extension of the attainment date of a previously established NAAQS, and imposes no additional requirements. For that reason, this action:

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

• Does not contain any unfunded mandate or significantly or uniquely affect small governments and therefore does not impose any additional enforceable duties, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104–4).

• Does not have a substantial direct effect on one or more Indian Tribes, on the relationship between the Federal Government and Indian Tribes, or on the distribution of power and responsibilities between the Federal Government and Indian Tribes, as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), nor will it have substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132 (64 FR 43255, August 10, 1999), because it merely determines that an area has attained a Federal standard, and does not alter the relationship or the distribution of power and responsibilities established in the CAA.

• Is not subject to Executive Order 13045 (62 FR 19885, April 23, 1997), because it is not economically significant.

• Is 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 Clean Air Act; and

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

• Does not affect the level of protection provided to human health or the environment because extending the attainment date does not alter the emission reduction measures that are required to be implemented in the Philadelphia Area, which is classified as moderate nonattainment for the 1997 8- hour ozone standard. See 69 FR at 23909 (April 30, 2004).

• Does not impose an information collection burden under the provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq. ).

If the Philadelphia Area were not granted an extension of its attainment date, EPA’s recourse would be to initiate a reclassification of the Philadelphia Area from its current classification of moderate nonattainment to serious nonattainment, pursuant to section 181(b)(2) of the CAA. Because the Philadelphia Area was formerly a severe nonattainment area under the revoked 1-hour ozone standard ( see 56 FR at 56773, November 6, 1991), it is required to continue to implement severe area requirements pursuant to EPA’s interpretation of ‘‘ anti-backsliding’’ provision of section 172(e) of the CAA. See 69 FR at 23973, April 30, 2004, South Coast Air Quality Management District v. EPA, 472 F.3d 882 (DC Cir. 2006), modified and rehearing den., 489 F.3d 1245 (DC Cir. 2007). The severe area requirements are more stringent than both the moderate and serious area requirements set forth in Title I, Part D, Subpart 2 of the CAA. Therefore, even if EPA were to not grant the attainment date extension and instead move to reclassify the area to serious nonattainment, no additional emission reduction measures would be required to be implemented in the Philadelphia Area through a 181(b)(2) reclassification.
