Approval and Promulgation of Implementation Plans for the State of Alabama: Cross-State Air Pollution Rule

The Environmental Protection Agency (EPA) is taking direct final action to approve the State of Alabama's March 27, 2015, State Implementation Plan (SIP) revision, submitted by the Alabama Department of Environmental Management (ADEM). This SIP revision provides Alabama's state-determined allowance allocations for existing electric generating units (EGUs) in the State for the 2016 control periods and replaces the 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 nonattainment and maintenance areas. In this direct final action, EPA is approving Alabama's 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. The CSAPR FIPs for Alabama remain in place until such time as the State decides to replace the FIPs with a SIP revision to allocate trading program allowances for control periods 2017 and beyond. EPA is taking direct final action to approve Alabama's 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.
