(j) EPA approves the one hour ozone attainment demonstration SIP for the Philadelphia-Wilmington-Trenton area submitted by the Pennsylvania Department of Environmental Protection on April 30, 1998, August 21, 1998, February 25, 2000 and July 19, 2001 including its RACM analysis and determination. EPA is approving the enforceable commitments made to the attainment plan for the Philadelphia-Wilmington-Trenton severe ozone nonattainment area submitted by the Pennsylvania Department of Environmental Protection on July 31, 1998, February 25, 2000 and July 19, 2001. The enforceable commitments are to:

(k) EPA approves the following mobile budgets of the post-1996 rate of progress plans and the 2005 attainment plan:

(l) EPA approves the Commonwealth of Pennsylvania's revised 1990 and the 2005 VOC and NO_X highway mobile emissions inventories and the 2005 motor vehicle emissions budgets for the 1-hour ozone attainment SIP for the Philadelphia-Wilmington-Trenton severe ozone nonattainment area. These revisions were submitted by the Pennsylvania Department of Environmental Protection on January 17, 2003. Submission of these revised MOBILE6-based motor vehicle emissions inventories was a requirement of EPA's approval of the attainment demonstration under paragraph (j) of this section.

(m) Determination - EPA has determined that, as of July 27, 2007, the Franklin County ozone nonattainment area has attained the 1-hour ozone standard and that the following requirements of section 172(c)(2) of the Clean Air Act do not apply to this area for so long as the area does not monitor any violations of the 1-hour ozone standard of 40 CFR 50.9: the attainment demonstration and reasonably available control measure requirements of section 172(b)(1), the reasonable further progress requirement of section 172(b)(2), and the related contingency requirements of section 172(c)(9). If a violation of the 1-hour ozone NAAQS is monitored in the Franklin County 1-hour ozone nonattainment area, these determinations shall no longer apply.

This determination, in accordance with 40 CFR 51.918, suspends the requirements for this area to submit an attainment demonstration, associated reasonably available control measures, a reasonable further progress plan, contingency measures, and other planning SIPs related to attainment of the standard for as long as this area continues to meet the 1997 8-hour ozone NAAQS.

(t) On July 14, 2012, Pennsylvania repealed the provisions set forth in Sections 130.101 through 130.108 pertaining to Portable Fuel Containers. Pennsylvania's regulations in the Pennsylvania State Implementation Plan were removed because they are superseded by more stringent Federal requirements codified at 40 CFR 59.600 through 59.699, relating to control of evaporative emissions from new and in-use portable fuel containers.
