Regulation No. 1150 - "Outer Continental Shelf Air Regulations"



Section 328(a)(1) of the Clean Air Act requires the EPA to establish requirements to control air pollution from outer continental shelf (OCS) sources in order to attain and maintain Federal and State ambient air quality standards and to comply with the provisions of part C of title I of the Act.  40 CFR Part 55 Outer Continental Shelf Air Regulations establishes the air pollution control requirements for OCS sources and the procedures for implementation and enforcement of the requirements, consistent with the stated objectives of section 328(a)(1) of the Act.

Delaware is proposing to adopt a new regulation which will incorporate by reference the provisions of 40 CFR Part 55.  40 CFR Part 55 is currently implemented and enforced by the EPA, specifically incorporates many of Delaware’s existing air regulations, and makes those regulations applicable to OCS sources (i.e., generally within 25 miles of the State's seaward boundary).  This adoption will enable the EPA to delegate to Delaware primary responsibility to implement and enforce these OCS requirements, as opposed to the EPA.
