Hey Barack -- thanks for the oil slick!
Clean Water Act - Section 311
(A) If a discharge, or a substantial threat of a discharge,
of oil or a hazardous substance from a vessel, offshore

limited to fish, shellfish, wildlife, other natural
resources, and the public and private beaches and

direct all Federal, State, and private actions to
