## Abstract

EPA is finalizing an update to a portion of the Outer Continental Shelf ("OCS") Air Regulations proposed in the Federal Register on February 10, 2011. Requirements applying to OCS sources located within 25 miles of States' seaward boundaries must be updated periodically to remain consistent with the requirements of the corresponding onshore area, as mandated by section 328(a)(1) of the Clean Air Act ("the Act"). The portion of the OCS air regulations being updated pertains to the requirements for OCS sources in 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 to be incorporated by reference into the Code of Federal Regulations and is listed in the appendix to the OCS air regulations.
