Approval and Promulgation of Air Quality Implementation Plans; Maryland; Infrastructure Requirements for the 2008 Ozone National Ambient Air Quality Standards

The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted by the State of Maryland 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 the basic program elements including, but not limited to regulatory structure, monitoring, modeling, legal authority, and adequate resources necessary to assure attainment and maintenance of the standards. These elements are referred to as infrastructure requirements. The State of Maryland has made a submittal addressing the infrastructure requirements for the 2008 ozone NAAQS.
