Air Plan Approval; AL, FL, GA, KY, MS, NC, SC, TN; Interstate Transport for the 2012 PM2.5

The Environmental Protection Agency (EPA) is proposing to approve portions of State Implementation Plan (SIP) submissions from Alabama, Florida, Georgia, Kentucky, Mississippi, North Carolina, South Carolina, and Tennessee addressing the Clean Air Act (CAA or Act) interstate transport infrastructure SIP requirements for the 2012 Fine Particulate Matter (PM 2.5 ) National Ambient Air Quality Standards (NAAQS). The CAA requires that each state adopt and submit a SIP for the implementation, maintenance, and enforcement of each NAAQS promulgated by EPA, commonly referred to as an ``infrastructure SIP.'' EPA is proposing to approve the interstate transport portions of these infrastructure SIPs for the aforementioned states as demonstrating that air emissions in the states do not significantly contribute to nonattainment or interfere with maintenance of the 2012 PM 2.5  NAAQS in any other state.
