## Abstract

The Environmental Protection Agency (EPA) is updating 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 (CAA). The portion of the OCS air regulations that is being updated pertains to the requirements for OCS sources for which Delaware is the designated COA. The State of Delaware's requirements discussed in this document are incorporated by reference into the Code of Federal Regulations and listed in the appendix to the federal OCS air regulations.
