Approval and Promulgation of Implementation Plans; South Carolina; Infrastructure Requirements for the 2008 Lead National Ambient Air Quality Standards

The Environmental Protection Agency (EPA) is taking final action to approve the September 20, 2011, State Implementation Plan (SIP) submission, provided by the South Carolina Department of Health and Environmental Control (SC DHEC) for inclusion into the South Carolina SIP. This final action 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. SC DHEC certified that the South Carolina SIP contains provisions to ensure the 2008 Lead NAAQS is implemented, enforced, and maintained in South Carolina. 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 South Carolina's infrastructure SIP submission, provided to EPA on September 20, 2011.
