What the agency says
The Environmental Protection Agency (EPA) is proposing to approve under the Clean Air Act (CAA), the Second Maintenance Plan for the Harrisburg-Lebanon-Carlisle and York Maintenance Area (Harrisburg- York Area) for the 2006 Fine Particulate Matter national ambient air quality standard (NAAQS) (Second 10-Year Maintenance Plan) as a revision to the state implementation plan (SIP). The SIP revision, submitted on February 7, 2025 by the Pennsylvania Department of Environmental Protection (PADEP), addresses the second 10-year maintenance period for particulate matter with an aerodynamic diameter less than or equal to a nominal 2.5 micrometers ([micro]m), commonly known as fine particulate matter or PM<INF>2.5</INF>. The Plan includes, among other elements, a base year emissions inventory, a maintenance demonstration, contingency provisions, and motor vehicle emissions budgets for use in transportation conformity determinations, to ensure the continued maintenance of the 2006 PM<INF>2.5</INF> NAAQS. The EPA is also proposing to find adequate and approve the motor vehicle emission budgets for the Harrisburg-York Area.
