## Abstract

EPA is taking direct final action to include in the regulations the revised applicability dates in the emissions user fees provision in 18 AAC 50.410. Requirements applying to Outer Continental Shelf ("OCS") sources located within 25 miles of States' seaward boundaries must be updated periodically to remain consistent with the emission user fee requirements of the corresponding onshore area ("COA"), as mandated by section 328(a)(1) of the Clean Air Act ("the Act"). The portion of the OCS air regulations that is being updated pertains to the requirements for OCS sources operating off of the State of Alaska. The intended effect of approving the OCS requirements for the State of Alaska is to regulate emissions from OCS sources in a manner consistent with the requirements onshore. The change to the existing requirements discussed below is incorporated by reference into the regulations and is listed in the appendix to the OCS air regulations.
