Title 42 › CHAPTER 85 — AIR POLLUTION PREVENTION AND CONTROL › SUBCHAPTER III — GENERAL PROVISIONS › § 7627
The EPA Administrator must make rules to control air pollution from oil and gas activities on parts of the Outer Continental Shelf. The rules had to be made within 12 months after November 15, 1990, and the Administrator must consult the Secretary of the Interior and the Commandant of the U.S. Coast Guard. The rule covers OCS areas off the Pacific, Arctic, and Atlantic coasts (except the North Slope Borough of Alaska) and off the Gulf Coast of Florida east of longitude 87°30′. Any OCS source within 25 miles of a State’s seaward boundary must follow the same pollution rules that would apply if it were onshore, including limits, permits, monitoring, testing, reporting, and offsets. New OCS sources must follow the rules when they are issued. Existing sources must comply within 24 months. The Administrator can grant a written exemption if a control is technically impossible or would dangerously threaten health or safety, but must replace it with a rule as close in strength as possible, require offsets for any added emissions, and allow public notice and comment. States next to these OCS areas can write and ask to run the programs themselves; EPA can delegate authority if the State rules are adequate, but EPA can still enforce the rules. OCS sources and related vessel emissions within 25 miles are treated as OCS emissions and the rules are enforced like regular onshore Clean Air Act standards. For OCS areas next to Texas, Louisiana, Mississippi, Alabama, and the North Slope Borough, the Secretary of the Interior must work with the EPA to coordinate rules. The Secretary must finish, within 3 years of November 15, 1990, a study on OCS emissions where those areas fail ozone or nitrogen dioxide standards, then consult EPA about any needed actions. Money may be appropriated as needed for that study. Also, the study and the regulatory parts of section 7412(n) apply to coastal waters of the States covered above in the same way they apply to the Great Lakes and the Chesapeake Bay. Definitions: Outer Continental Shelf (per the OCS Lands Act); corresponding onshore area (nearest affected onshore area); OCS source (equipment, activities, or facilities on the OCS, including platforms, drill ships, and servicing vessels); new versus existing OCS sources follow the Clean Air Act definitions.
