## Abstract

The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted by the Commonwealth of Virginia 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. The Commonwealth of Virginia made a submittal addressing the infrastructure requirements for the 2010 sulfur dioxide (SO<INF>2</INF>) primary NAAQS.
