The Environmental Protection Agency (EPA) is finalizing approval of portions of five State Implementation Plan (SIP) revisions submitted by the State of Florida, Department of Environmental Protection (FDEP), through the Florida Division of Air Resource Management, on June 23, 1999, July 1, 2011, December 12, 2011, February 27, 2013, and February 1, 2017. Florida's SIP revisions recodify, clarify, and reorganize the State's non-title V air permitting and compliance assurance program regulations consistent with flexibility provided under the Clean Air Act (CAA or Act) and EPA's rules which address new source preconstruction permitting. EPA is finalizing approval of Florida's SIP revisions on the basis that they are consistent with the CAA and EPA's requirements for permitting air emission sources.
