The Environmental Protection Agency (EPA) is finalizing an update to 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 the Clean Air Act (CAA). The portion of the OCS air regulations that is being updated here pertains to the requirements for OCS sources for which the State of New York is the COA. The intended effect of updating the OCS requirements for the State of New York is to regulate emissions from OCS sources in accordance with the requirements onshore. The requirements discussed in this rule are being incorporated by reference into the OCS air regulations.
