The Environmental Protection Agency (EPA) is taking final action to approve portions of the October 14, 2011, State Implementation Plan (SIP) submission, provided by the State of Florida, through the Department of Environmental Protection (FL DEP) for inclusion into the Florida SIP. This final submission pertains to the Clean Air Act (CAA or the Act) infrastructure requirements for the 2008 Lead national ambient air quality standards (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. FL DEP certified that the Florida SIP contains provisions that ensure the 2008 Lead NAAQS is implemented, enforced, and maintained in Florida. With the exception of provisions pertaining to prevention of significant deterioration (PSD) permitting which EPA has already approved, EPA is taking final action to approve Florida's infrastructure submission, provided to EPA on October 14, 2011, as satisfying the required infrastructure elements for the 2008 Lead NAAQS.
