The Honorable Edward G. Rendell Governor of the Commonwealth of Pennsylvani a 225 Main Capital Building Harrisburg, Pennsy lvania 17120 Dear Governor Rendell: On April 14, 2010, the Pennsy lvania Department of Environmental Protection (PADEP) provided the U.S. Environmental Protection Agency (EPA) Region I II Office with a revised state implementation plan (SI P) submission regarding the attainment demonstration requirements for the 1997 fine particulate matter (PM 2.5 ) national ambient air quality standards (NAAQS) for the Pennsy lvania portion of the Philadelphia
- Wilmington, Pennsy lvania
- New Jersey - Delaware PM 2.5 nonattainment area (hereafter referred to as the Philadelphia area). We reviewed this submission and made the determination that it met the requirements for completeness found in Section 110(k)(1) of the Clean Air A ct (CAA) on April 23, 2010. The CAA requires states with areas that are designated nonattainment for the 1997 PM 2.5 NAAQS, to develop a SI P describing how the state will attain and maintain the PM 2.5 NAAQS (attainment demonstration) within three y ears of the effective date of the designation. Effective April 5, 2005, EPA designated the Pennsy lvania portion of the Philadelphia area as nonattainment for PM 2.5 NAAQS. As a result of this nonattainment designation, the Pennsy lvania portion of the Philadelphia area was required to provide EPA with an attainment demonstration by

April 5, 2008. On November 27, 2009 (74 FR 62251), EPA issued a finding of failure to submit the 1997 PM 2.5 NAAQS attainment demonstration for the Pennsylvania portion of the Philadel phia area. This finding started an 18
- month sanctions clock for a two for one new source offset, and six months later, highway sanctions, if the deficiency was not corrected. To correct this deficiency , the Pennsy lvania portion of the Philadelphia area w as required to provide a submission that EPA could deem complete pursuant to Section 110(k)(1) of the CAA and the “Criteria for Determining the Completeness of Plan Submissions,” as described in 40 CFR Part 51, Appendix V.**Printed on 100% recycled/recyclable paper with 100% post -**  **consumer fiber and process chlorine free. Customer Service Hotline: 1**  **- 800**  **- 438**  **- 2474**  EPA has reviewed the April 14 , 2010 submission that comprises Pennsy lvania’s attainment demonstration for the Pennsylvania portion of the Philadelphia area. On April 23, 2010, EPA sent a letter to PADEP stating that EPA has determined that this submission meets the completeness deter mination requirements. This completeness determination for the attainment demonstration terminates the sanctions clock; thus, sanctions will not take effect in this area as a result of the finding of failure to submit previously made on November 27, 2009. EPA is currently

reviewing the approvability of this submission and will make its final determination through rulemaking in the Federal Register
