Approval and Promulgation of Implementation Plans; Florida; Sections 128 and 110(a)(1) and (2) Infrastructure Requirements for the 1997 8-Hour Ozone 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 December 13, 2007, and supplemented on April 18, 2008 and May 24, 2012, to demonstrate that the State meets the requirements of sections 110(a)(1) and (2) of the Clean Air Act (CAA or Act) for the 1997 8-hour ozone national ambient air quality standards (NAAQS). Section 110(a) of 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. FDEP certified that the Florida SIP contains provisions that ensure the 1997 8-hour ozone NAAQS are implemented, enforced, and maintained in Florida (hereafter referred to as ``infrastructure submission''). EPA is now taking three related actions on FDEP's infrastructure submissions for Florida. First, EPA is taking final action to disapprove in part portions of sections 110(a)(2)(C) and 110(a)(2)(J) of the December 13, 2007, submittal as it relates to the regulation of greenhouse gas (GHG) emissions. Second, EPA is taking final action to approve FDEP's May 24, 2012, submission, which addresses the substantive requirements of section 128 relating to State board requirements as applicable to the infrastructure SIP pursuant to section 110(a)(2)(E)(ii), and the substantive requirements of section 110(a)(2)(G), which relates to the authority to implement emergency powers under section 303 of the CAA. Third, and with the exception of the aforementioned portions of sections 110(a)(2)(C) and (J), EPA is finalizing its determination that Florida's infrastructure submission, provided to EPA on December 13, 2007, supplemented on April 18, 2008, addresses all other required infrastructure elements for the 1997 8- hour ozone NAAQS.
