"During the debate on the 1976 Act, Senator Gravel of Alaska criticized the concept of federal management on one side of the three mile line and state management on the other, because freely travel across the three mile line." Congress tossed Ted Stevens idea in the ditch. "But, Congress instead approved a more modest substitute offered by the bill's other manager, Senator Magnusen, directing the Councils, if possible, to incorporate state management procedures."
