The EPA is finalizing a full approval of the Best Available Retrofit Technology (BART) determinations addressed in the Agency's May 25, 2012, proposed rulemaking action on a regional haze state implementation plan (SIP) submitted by the State of Florida, through the Florida Department of Environmental Protection (FDEP). These BART determinations were submitted to the EPA in a draft regional haze SIP on April 13, 2012, for parallel processing, and re-submitted in final form on September 17, 2012. Specifically, the portion of Florida's September 17, 2012, regional haze SIP that is being acted upon in this final action addresses some of the requirements of the Clean Air Act (CAA or Act) and the EPA's rules that require states to prevent any future and remedy any existing anthropogenic impairment of visibility in mandatory Class I areas (national parks and wilderness areas) caused by emissions of air pollutants from numerous sources located over a wide geographic area (also referred to as the "regional haze program"). States are required to assure reasonable progress toward the national goal of achieving natural visibility conditions in Class I areas. The EPA will take separate action at a later date to address the remainder of Florida's September 17, 2012, regional haze SIP.
