Alaska Statutes Title 46. Water, Air, Energy, and Environmental Conservation § 46.14.500. Air pollution from outer continental shelf activities

(a) The department shall seek delegation of authority from the federal administrator to implement and enforce the terms and provisions of 42 U.S.C. 7627 (Clean Air Act, sec. 328) for the Pacific and Arctic Ocean areas offshore of the state.  The department may adopt regulations that are necessary to acquire this delegated authority.

(b) In adopting regulations under this section, the department shall ensure that stationary sources located within 25 miles of the seaward boundary of the state are subject to the same air quality control requirements that would be applicable if the stationary source were located in the corresponding onshore area.  For purposes of this subsection, stationary sources located within 25 miles of the seaward boundary of the state include a vessel servicing or associated with the stationary source while at the stationary source or en route to or from the stationary source and within 25 miles of the stationary source.

(c) In this section, “corresponding onshore area” means, with respect to a stationary source located within 25 miles of the seaward boundary of the state, the onshore attainment or nonattainment area that is closest to the stationary source, unless the commissioner determines that another area with more stringent requirements relating to control and abatement of air pollution may reasonably be expected to be affected by emissions from the offshore stationary source;  this determination shall be based on the potential for air pollutants from the stationary source to reach the other onshore area and the potential of the air pollutants to affect the efforts of the other onshore area to attain or maintain a federal ambient air quality standard set under 42 U.S.C. 7470--7492 (Clean Air Act, secs. 160--169b) or a state equivalent.
