Outer Continental Shelf Air Regulations; Consistency Update for California

EPA is finalizing the updates of the Outer Continental Shelf ("OCS") Air Regulations proposed in the Federal Register on December 1, 2005 and July 6, 2005. 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 Amendments of 1990 ("the Act"). The portions of the OCS air regulations that are being updated pertain to the requirements for OCS sources for which the Santa Barbara County Air Pollution Control District, South Coast Air Quality Management District, State of California and Ventura County Air Pollution Control District are the designated COAs. The intended effect of approving the requirements contained in "Santa Barbara County Air Pollution Control District Requirements Applicable to OCS Sources" (February, 2006), "South Coast Air Quality Management District Requirements Applicable to OCS Sources" (Parts I, II and III) (February, 2006), "State of California Requirements Applicable to OCS Sources" (February, 2006), and "Ventura County Air Pollution Control District Requirements Applicable to OCS Sources" (February, 2006) is to regulate emissions from OCS sources in accordance with the requirements onshore.
