primary and secondary 24-hour standard of 65 11⁄4g1m3 determined by the three-year average of the 98thpercentile of 24-hour concentrations. Implementation of the standard was delayed due to legal challenges.

In the Commonwealth of Pennsylvania, EPA designated eight areas comprised of all or parts of 21 counties

as PM2.5 nonattainment areas for the annual standard. For each nonattainment area, the Commonwealth is

required to develop a State Implementation Plan (SIP) revision that demonstrates how the area will attain

the standard by the prescribed attainment date, April 5, 2010. The Pennsylvania Department of

Environmental Protection (Department) Is seeking public comment on the SIP revision for the Philadelphia

Wilmington, PA-NJ-DE PM2.5 nonattainment area (Philadelphia PM2.5 Area.) The proposed SIP revision

contains information on PM2.5 trends and emissions to demonstrate that the Philadelphia PM2.5 Area meetsall requirements necessary for an approvable SIP revision. The proposed SIP revision demonstrates how thearea will attain the PM2.5 standard by April 5, 2010, by presenting evidence from air quality modeling,

emission trends, regional pollutant transport impacts and emission reductions through state and federalcontrol measures. In addition, the proposed revision to the SIP contains the base-year 2002 emissions

inventory, mobile source emission budgets for purposes of transportation conformity and a contingency plan

to bring the area back into attainment should future violations of the standard occur. After consideration of

comments received, the SIP revision will befinalized and submitted to EPA for approval. In addition, the

Department is seeking public comment on a proposed SIP revision to correct the Stationary Point Source

Annual Emissions included in the 2002 Base-Year Inventory submitted to EPA on August 29, 2007, for the

Pennsylvania portion of the Philadelphia-Wilmington-Atlantic City, PA-N3-DE Eight-Hour OzoneNonattainment Area. The proposed PM2.5 SIP revision for the Philadelphia PM2.5 Area and the proposed
