# SUPPLEMENTARY INFORMATION:

                    On March 3, 2009 we solicited public comment on a proposal to update a portion of the Outer Continental Shelf (“OCS”) Air Regulations. 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 (“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 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 accordance with the requirements onshore. The change to the existing requirements discussed below is proposed to be incorporated by reference into the Code of Federal Regulations and is listed in the appendix to the OCS air regulations.                     *See*74 FR 9180. In the proposal, we stated that EPA would accept public comments on the proposal until April 2, 2009.                

                    During the public comment period that ended on April 2, 2009, the North Slope Borough asked for an extension of the public comment period. In light of the North Slope Borough's interest in this proposal, we are extending the public comment period to                     *May 13, 2009,*                     to provide additional time for interested parties to submit written comments. All written comments received by                     *May 13, 2009,*                     will be considered in our final action.
