## Abstract

EPA is taking direct final action to approve an update to a portion of the Outer Continental Shelf (OCS) Air Regulations. Requirements applying to OCS sources located within 25 miles of a State's seaward boundary must be updated periodically to maintain continuity and ensure consistency with the regulations of the corresponding onshore area (COA), as mandated by the Clean Air Act Amendments of 1990 (CAA). The specific portion of the OCS air regulation that is being updated pertains to the requirements for OCS sources in the Commonwealth of Virginia (Virginia). The intended effect of approving the OCS requirements for Virginia is to regulate emissions from OCS sources in accordance with the requirements onshore.
