A bill to establish a 200-mile Marine Pollution Control Zone.

Amends the Federal Water Pollution Control Act of 1972 to redefine the term "navigable waters" as it applies to regulation of discharges of oil and hazardous substances and to regulation of marine sanitation devices to include the belt of seas extending 197 nautical miles from the outer limit of the territorial seas. Stipulates that such boundary shall be reduced to a line equidistant between the United States and a foreign nation where such line of equidistance between the two countries is less than 200 miles.

Authorizes the Attorney General to initiate class actions to recover private claims arising from discharges of oil and hazardous substances. Authorizes the Administrator of the Environmental Protection Agency to act as trustee of the natural resources of the navigable waters in recovering damages caused by oil or hazardous substances in accordance with prescribed criteria in assessing the amount of such damages.
