ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 81

[EPA-R03-OAR-2010-0574; FRL-9223-1]

 
Approval of One-Year Extension for Attaining the 1997 8-Hour 
Ozone Standard for the Delaware, Maryland, and Pennsylvania Portions of 
the Philadelphia-Wilmington-Atlantic City Moderate Nonattainment Area

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to extend the attainment date from June 15, 
2010 to June 15, 2011 for the Delaware, Maryland, and Pennsylvania 
portions of the Philadelphia-Wilmington-Atlantic City nonattainment 
area (Philadelphia Area), which is classified as moderate for the 1997 
8-hour ozone national ambient air quality standard (NAAQS). This 
extension is based in part on air quality data recorded during the 2009 
ozone season. Specifically, the Philadelphia Area's 4th highest daily 
8-hour monitored ozone value during the 2009 ozone season is 0.084 
parts per million (ppm) or less. Accordingly, EPA is revising the 
tables concerning the 8-hour ozone attainment dates for the 
Philadelphia Area in the States of Delaware and Maryland, and the 
Commonwealth of Pennsylvania. EPA is proposing to approve the extension 
of the attainment date for the Delaware, Maryland, and Pennsylvania 
portions of the Philadelphia Area in accordance with the requirements 
of the Clean Air Act (CAA). EPA is proposing to approve the extension 
of the attainment date for the New Jersey portion of the Philadelphia 
Area in a separate rulemaking in this Federal Register.

SUPPLEMENTARY INFORMATION: 

I. Requests for Attainment Date Extension for the Philadelphia Area

    The Commonwealth of Pennsylvania and the States of Maryland and 
Delaware (the States) requested a one-year attainment date extension 
for the Philadelphia Area on January 8, 2010, March 12, 2010, and May 
18, 2010, respectively. The Philadelphia Area, which is classified as 
moderate for the 1997 8-hour ozone 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 CAA, is June 15, 2010. The 
States' requested that the attainment date be extended to June 15, 
2011. As stated above, EPA is approving the extension of the attainment 
date for the New Jersey portion of the Philadelphia Area in a separate 
rulemaking notice in today's Federal Register.

II. CAA Requirements and EPA Actions Regarding One-Year Extensions

    Section 172(a)(2)(C) of subpart 1 of the CAA provides for EPA to 
extend the attainment date for an area by one year if the State has 
complied with all the requirements and commitments pertaining to the 
area in the applicable implementation plan and no more than a minimal 
number of exceedances of the NAAQS has occurred in the attainment year. 
Up to two one-year extensions may be issued for a single nonattainment 
area. Section 181(a)(5) of subpart 2 contains a similar provision for 
the ozone NAAQS, but instead of providing for an extension where there 
has been a ``minimal'' number of exceedances, it allows an extension 
only if there is no more than one exceedance of the NAAQS in the year 
proceeding the extension year. However, the language in section 
181(a)(5) reflects the form of the 1-hour ozone NAAQS and not the 1997 
8-hour ozone NAAQS. 40 CFR

[[Page 68737]]

51.907 sets forth how sections 172(a)(2)(C) and 181(a)(5) apply to an 
area subject to the 1997 8-hour ozone NAAQS. Under 40 CFR 51.907, an 
area will meet the requirement of section 172(a)(2)(C)(ii) or 
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 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; and
    (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 are measured at 0.084 ppm or less 
(Table 1), as required by 40 CFR 51.907(a). The monitoring data has 
been quality controlled and quality assured. In the Technical Support 
Document (TSD) for this action, EPA evaluates the air quality 
monitoring data for the Philadelphia Area. For details, please refer to 
EPA's TSD.

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

    EPA has determined that the requirements for a one-year extension 
of the attainment date have been fulfilled as follows:
    (1) The States have complied with all requirements and commitments 
pertaining to the area in the applicable ozone implementation plan. The 
applicable ozone implementation plans can be found at 40 CFR 52.420, 40 
CFR 52.1070, 40 CFR 52.2020, for the States of Delaware, Maryland, and 
Pennsylvania, respectively; and
    (2) The Philadelphia Area's 4th highest daily 8-hour monitored 
value during the 2009 ozone season is 0.084 ppm or less.
    Therefore, EPA approves the States' attainment date extension 
requests for the Delaware, Maryland, and Pennsylvania portions of the 
Philadelphia Area. As a result, the charts in 40 CFR 81.308, 40 CFR 
81.321, and 40 CFR 81.339 are being modified to reflect EPA's approval 
of the States' attainment date extension request. Those charts are 
entitled ``Delaware-Ozone (8-Hour Standard)'', ``Maryland-Ozone (8-Hour 
Standard)'', and ``Pennsylvania-Ozone (8-Hour Standard)'', 
respectively.

III. Proposed Action

    EPA is proposing to approve the attainment date extension from June 
15, 2010 to June 15, 2011 for the Delaware, Maryland, and Pennsylvania 
portions of the Philadelphia Area, which is classified as moderate for 
the 1997 8-hour ozone NAAQS. EPA is soliciting public comments on the 
issues discussed in this document. These comments will be considered 
before taking final action.

IV. Statutory and Executive Order Reviews

    Under the CAA, the Administrator is required to approve a SIP 
submission that complies with the provisions of the Act and applicable 
Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in 
reviewing SIP submissions, EPA's role is to approve State choices, 
provided that they meet the criteria of the CAA. Accordingly, this 
action merely proposes to approve State law as meeting Federal 
requirements and does not impose additional requirements beyond those 
imposed by State law. For that reason, this proposed action:
     Is not a ``significant regulatory action'' subject to 
review by the Office of Management and Budget under Executive Order 
12866 (58 FR 51735, October 4, 1993);
     Does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
     Is 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.);
     Does 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);
     Does not have Federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
     Is not an economically significant regulatory action based 
on health or safety risks subject to Executive Order 13045 (62 FR 
19885, April 23, 1997);

[[Page 68738]]

     Is not a significant regulatory action subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001);
     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).
    In addition, this proposed extension of the attainment deadline for 
the 1997 8-hour ozone NAAQS for the Delaware, Maryland, and 
Pennsylvania portions of the Philadelphia Area does not have Tribal 
implications as specified by Executive Order 13175 (65 FR 67249, 
November 9, 2000), because the SIP is not approved to apply in Indian 
country located in the State, and EPA notes that it will not impose 
substantial direct costs on Tribal governments or preempt Tribal law.
