Pursuant to Section 181 (a)(5) of the Clean Air Act (CAA), which provides for an

extension of attainment dates under certain conditions, I am requesting that the U.S.

Environmental Protection Agency (EPA) extend by one year the June 15, 2010, attainment datefor the Philadelphia-Wilmington-Atlantic City (PA-DE-NJ-MD) eight-hour ozone nonattainmentarea (Philadelphia Area). This area is classified as a “moderate” nonattainment area for the 1997eight-hour ozone National Ambient Air Quality Standard (NAAQS). Under Section 181 (a)(5) of

the CAA, EPA may grant up to two one-year extensions of attainment dates.

The request to extend the attainment date for the Philadelphia Area for the 1997

eight-hour ozone NAAQS to June 15, 2011, is partially based on 2009 ozone season monitoringdata. By this letter, I am certifying that:

1) The Commonwealth of Pennsylvania has complied with all requirements and

commitments pertaining to the area in the applicable ozone implementation plan; and

2) The Philadelphia-Wilmington-Atlantic City (PA-DE-NJ-MD) nonattainment area’s 4

highest daily eight-hour monitored value during the 2009 ozone season is 0.084 ppm or

less. See enclosed letter certifying that Pennsylvania’s ozone air quality data in

the EPA Air Quality System is complete, quality-assured ambient air quality monitoring

data for the 2009 ozone season.
