Approval and Promulgation of Air Quality Implementation Plans; West Virginia; Removal of Clean Air Interstate Rule Trading Programs Replaced by Cross-State Air Pollution Rule Trading Programs

Riepilogo

The Environmental Protection Agency (EPA) is taking direct final action to approve two state implementation plan (SIP) revisions submitted by the State of West Virginia. These revisions pertain to two West Virginia regulations that established trading programs under the Clean Air Interstate Rule (CAIR). The EPA-administered trading programs under CAIR were discontinued on December 31, 2014 upon the implementation of the Cross-State Air Pollution Rule (CSAPR), which was promulgated by EPA to replace CAIR. CSAPR established federal implementation plans (FIPs) for 23 states, including West Virginia. The submitted SIP revisions request removal of regulations that implemented the CAIR annual nitrogen oxide (NO X ) and annual sulfur dioxide (SO 2 ) trading programs from the West Virginia SIP (as CSAPR has supplanted CAIR). West Virginia's SIP revision submittal requesting removal of a regulation that implemented the CAIR ozone season trading program will be addressed in a separate action. EPA is approving these SIP revisions in accordance with the requirements of the Clean Air Act (CAA).
