The Environmental Protection Agency (EPA) is proposing to approve portions of a draft revision to the South Carolina State Implementation Plan (SIP) concerning the Cross-State Air Pollution Rule (CSAPR) that was submitted by South Carolina for parallel processing on May 26, 2017. Under CSAPR, large electricity generating units (EGUs) in South Carolina are subject to Federal Implementation Plans (FIPs) requiring the units to participate in CSAPR's federal trading program for annual emissions of nitrogen oxides (NO<INF>X</INF>) and one of CSAPR's two federal trading programs for annual emissions of sulfur dioxide (SO<INF>2</INF>). This action would approve the State's regulations requiring large South Carolina EGUs to participate in new CSAPR state trading programs for annual NO<INF>X</INF> and SO<INF>2</INF> emissions integrated with the CSAPR federal trading programs, replacing the corresponding FIP requirements. These CSAPR state trading programs are substantively identical to the CSAPR federal trading programs, with the State retaining EPA's default allowance allocation methodology and EPA remaining the implementing authority for administration of the trading program. EPA is proposing to approve the portions of the draft SIP revision concerning these CSAPR state trading programs because these portions of the draft SIP revision meet the requirements of the Clean Air Act (CAA or Act) and EPA's regulations for approval of a CSAPR full SIP revision replacing the requirements of a CSAPR FIP. Under the CSAPR regulations, approval of these portions of the draft SIP revision would automatically eliminate South Carolina units' obligations to participate in CSAPR's federal trading programs for annual NO<INF>X</INF> and SO<INF>2</INF> emissions under the corresponding CSAPR FIPs addressing interstate transport requirements for the 1997 Annual Fine Particulate Matter (PM<INF>2.5</INF>) national ambient air quality standards (NAAQS). Approval of these portions of the SIP revision would satisfy South Carolina's good neighbor obligation for the 1997 Annual PM<INF>2.5</INF> NAAQS.
