## Abstract

The Environmental Protection Agency (EPA) is approving most elements of a state implementation plan (SIP) revision submitted by the Pennsylvania Department of Environmental Protection (PADEP) on behalf of the Allegheny County Health Department (ACHD) to address Clean Air Act (CAA or "the Act") requirements for the 2012 annual fine particulate matter (PM<INF>2.5</INF>) national ambient air quality standards (NAAQS or "standards") in the Allegheny County Moderate PM<INF>2.5</INF> nonattainment area (the "Allegheny County Area," or "the Area"). The revision constitutes a comprehensive plan to ensure the Allegheny County Area's timely attainment of the 2012 PM<INF>2.5</INF> NAAQS. EPA is approving this revision to the Pennsylvania SIP in accordance with the requirements of the CAA.
