The United States Environmental Protection Agency (EPA) is seeking public comment on a draft Clean Air Act (CAA) Outer Continental Shelf (OCS) air permit for Anadarko Petroleum Corporation (Anadarko). Anadarko has applied for an OCS air permit pursuant to section 328 of the Clean Air Act (CAA) from EPA Region 4. The proposed air permit will regulate air emissions from a proposed exploratory drilling operation within the eastern Gulf of Mexico of the OCS. The drilling area is located on the OCS east of longitude 87.5, west of the Military Mission Line (86°41’ west longitude), at least 100 miles from the Louisiana shoreline, and at least 125 miles from the Florida shoreline. The proposed project is for exploratory drilling and well completion and maintenance activities only, and will last no more than two years. The permit does not allow for establishment of any permanent production platforms.
