## Abstract

The Environmental Protection Agency (EPA) is finalizing the approval of a local rule and the update of the Outer Continental Shelf (OCS) Air Regulations proposed in the Federal Register on June 21, 2018. 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 for which the Santa Barbara County Air Pollution Control District ("Santa Barbara County APCD" or "the District") is the designated COA. The intended effect of approving the local rule and updating the OCS requirements for the Santa Barbara County APCD is to regulate emissions from OCS sources in accordance with the requirements onshore. The change to the existing requirements discussed in this document will be incorporated by reference into the Code of Federal Regulations and listed in the appendix to the OCS air regulations.
