The Oil Pollution Act of 1990 (OPA) establishes a framework that addresses the liability of responsible parties in connection with the discharge of oil into the navigable waters of the United States, adjoining shorelines, or the exclusive economic zone. Among other provisions, OPA limits certain liabilities of a responsible party in connection with discharges of oil into such areas. The liability limitations established by OPA are currently the subject of significant congressional interest in the wake of the Deepwater Horizon oil spill in the Gulf of Mexico.
