Approval and Promulgation of Air Quality Implementation Plans; State of South Carolina; Regional Haze State Implementation Plan

The Environmental Protection Agency (EPA) is approving a South Carolina State Implementation Plan (SIP) revision, submitted by the State of South Carolina through the South Carolina Department of Health and Environmental Control (SC DHEC) on December 28, 2012. South Carolina's December 28, 2012, SIP revision (``Progress Report'') addresses requirements of the Clean Air Act (CAA or ``Act'') and EPA's rules that require states to submit periodic reports describing progress towards reasonable progress goals (RPGs) established for regional haze and a determination of the adequacy of the State's existing SIP addressing regional haze (``regional haze plan''). EPA is finalizing approval of South Carolina's Progress Report on the basis that it addresses the progress report and adequacy determination requirements for the first implementation period for regional haze.
