The Environmental Protection Agency (EPA) is taking direct final action to approve revisions to the State Implementation Plan (SIP) submitted by the State of Kansas in a letter dated March 30, 2015. This SIP revision provides Kansas' state-determined allowance allocations for existing electric generating units (EGUs) in the State for the 2016 control periods and replaces certain allowance allocations for the 2016 control periods established by EPA under the Cross-State Air Pollution Rule (CSAPR). The CSAPR addresses the "good neighbor" provision of the Clean Air Act (CAA or Act) that requires states to reduce the transport of pollution that significantly affects downwind air quality. In this final action EPA is approving Kansas' SIP revision, incorporating the state-determined allocations for the 2016 control periods into the SIP, and amending the regulatory text of the CSAPR Federal Implementation Plan (FIP) to reflect this approval and inclusion of the state-determined allocations. EPA is taking direct final action to approve Kansas' SIP revision because it meets the requirements of the CAA and the CSAPR requirements to replace EPA's allowance allocations for the 2016 control periods. This action is being taken pursuant to the CAA and its implementing regulations. EPA's allocations of CSAPR trading program allowances for Kansas for control periods in 2017 and beyond remain in place until the State submits and EPA approves state-determined allowance allocations for those control periods through another SIP revision. The CSAPR FIPs for Kansas remain in place until such time as the State decides to replace the FIPs with a SIP revision.
