🌫️Approval of Updates to South Carolina's Cross-State Air Pollution Rule
The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted through the South Carolina Department of Health and Environmental Control (SC DHEC) on September 26, 2023, regarding updates to the State's Cross-State Air Pollution Rule (CSAPR) emissions trading programs. The SIP revision incorporates by reference (IBRs) certain amendments EPA has made to the regulations for the Federal CSAPR trading programs for annual emissions of nitrogen oxides (NO<INF>X</INF>) and sulfur dioxide (SO<INF>2</INF>) for large electric generating units (EGUs). EPA is approving South Carolina's September 26, 2023, SIP revision because it is consistent with EPA's good neighbor CSAPR trading programs and the Clean Air Act (CAA or Act).
