## Abstract

The Environmental Protection Agency (EPA) is approving portions of two State Implementation Plan (SIP) revisions submitted by the Commonwealth of Pennsylvania through the Pennsylvania Department of Environmental Protection (PADEP) pursuant to the Clean Air Act (CAA). Whenever new or revised National Ambient Air Quality Standards (NAAQS) are promulgated, the CAA requires states to submit a plan for the implementation, maintenance, and enforcement of such NAAQS. The plan is required to address basic program elements, including but not limited to regulatory structure, monitoring, modeling, legal authority, and adequate resources necessary to assure implementation, maintenance, and enforcement of the NAAQS. These elements are referred to as infrastructure requirements. PADEP made submittals addressing the infrastructure requirements for the 2008 ozone NAAQS and the 2010 sulfur dioxide (SO<INF>2</INF>) primary NAAQS.
