Approval and Promulgation of Implementation Plans; Florida; Prong 3 of Section 110(a)(2)(D)(i) Infrastructure Requirement for the 1997 and 2006 Fine Particulate Matter National Ambient Air Quality Standards

EPA is taking final action to approve in part, and disapprove in part, the State Implementation Plan (SIP) submissions, submitted by the State of Florida, through the Florida Department of Environmental Protection (FDEP) on April 18, 2008, and September 23, 2009. This final action addresses the Clean Air Act (CAA or Act) requirements pertaining to prevention of significant deterioration (PSD) for the 1997 annual and 2006 24-hour fine particulate matter (PM<INF>2.5</INF>) National Ambient Air Quality Standards (NAAQS) infrastructure SIPs. The CAA requires that each state adopt and submit a SIP for the implementation, maintenance, and enforcement of each NAAQS promulgated by EPA, which is commonly referred to as an "infrastructure" SIP. EPA is approving in part, and disapproving in part, the submission for Florida that relates to adequate provisions prohibiting emissions that interfere with any other state's required measures to prevent significant deterioration of its air quality. All other applicable infrastructure requirements for the 1997 annual and 2006 24-hour PM<INF>2.5</INF> NAAQS associated with Florida have been addressed in separate rulemakings.
