## Abstract

EPA is finalizing the update of the Outer Continental Shelf ("OCS") Air Regulations proposed in the Federal Register on October 9, 2012. 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 the Clean Air Act, as amended in 1990 ("the Act"). The portion of the OCS air regulations that is being updated pertains to the requirements for OCS sources for which the Ventura County Air Pollution Control District ("Ventura County APCD" or "District") is the designated COA. The intended effect of approving the OCS requirements for the Ventura County APCD is to regulate emissions from OCS sources in accordance with the requirements onshore.
