Approval and Promulgation of Implementation Plans; Florida; Infrastructure Requirements for the 2010 Sulfur Dioxide National Ambient Air Quality Standard

The Environmental Protection Agency (EPA) is proposing to approve the State Implementation Plan (SIP) submissions, submitted by the State of Florida, through the Florida Department of Environmental Protection (FDEP), on June 3, 2013, and supplemented on January 8, 2014, for inclusion into the Florida SIP. This proposal pertains to the infrastructure requirements of the Clean Air Act (CAA or Act) for the 2010 1-hour sulfur dioxide (SO 2 ) national ambient air quality standard (NAAQS). 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 submission.'' FDEP certified that the Florida SIP contains provisions that ensure the 2010 1-hour SO 2  NAAQS is implemented, enforced, and maintained in Florida. EPA is proposing to determine that Florida's infrastructure SIP submissions, provided to EPA on June 3, 2013, and supplemented on January 8, 2014, satisfy the required infrastructure elements for the 2010 1-hour SO 2  NAAQS.
