EPA Proposes Approval of Pennsylvania's Air Quality Implementation Plan for Philadelphia Area

The Environmental Protection Agency (EPA) is proposing to approve Pennsylvania's State Implementation Plan (SIP) for the Philadelphia-Wilmington-Trenton ozone nonattainment area, which includes a demonstration of one-hour ozone attainment. The EPA is also considering disapproval if Pennsylvania fails to submit a suitable motor vehicle emissions budget and adopt necessary rules for reducing nitrogen oxide emissions.
