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

The Environmental Protection Agency (EPA) is proposing to approve Maryland's State Implementation Plan (SIP) for the Philadelphia-Wilmington-Trenton nonattainment area, which includes a 1-hour ozone attainment demonstration submitted by the Maryland Department of the Environment (MDE) in 1998. The proposal also includes an alternative disapproval if Maryland fails to submit an adequate motor vehicle emissions budget and adopt regional NOx reduction rules.
