Start Preamble


Environmental Protection Agency (EPA).


Proposed rule.


The Environmental Protection Agency (EPA) is proposing to approve revisions to the State Implementation Plan (SIP) submitted by the State of Missouri in a letter dated March 30, 2015. This SIP revision provides Missouri's state-determined allowance allocations for existing electric generating units (EGUs) in the state for the 2016 control period 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 action EPA is proposing to approve Missouri'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. EPA is proposing to take direct final action to Start Printed Page 51152approve Missouri'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 proposed pursuant to the CAA and its implementing regulations. EPA's allocations of CSAPR trading program allowances for Missouri for control periods in 2017 and beyond remain in place until the State submits and EPA approves state-determined allocations for those control periods through another SIP revision. The CSAPR FIPs for Missouri remain in place until such time as the State decides to replace the FIPs with a SIP revision.


Comments on this proposed action must be received in writing by September 23, 2015.

In the final rules section of this Federal Register, EPA is approving the state's SIP revision as a direct final rule without prior proposal because the Agency views this as a noncontroversial revision amendment and anticipates no relevant adverse comments to this action. A detailed rationale for the approval is set forth in the direct final rule. If no relevant adverse comments are received in response to this action, no further activity is contemplated in relation to this action. If EPA receives relevant adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed action. EPA will not institute a second comment period on this action. Any parties interested in commenting on this action should do so at this time. Please note that if EPA receives adverse comment on part of this rule and if that part can be severed from the remainder of the rule, EPA may adopt as final those parts of the rule that are not the subject of an adverse comment. For additional information, see the direct final rule which is located in the rules section of this Federal Register.
