Hahn lifts his boot out of thick beached oil at Queen Bess Island in Barataria Bay, just off the Gulf of Mexico in Plaquemines Parish, La. Cleaning the oil far beyond the time the leak is capped will become the job of the U.S. Coast Guard and BP.

In this file photo made June 3, 2010, a brown pelican covered in oil sits on the beach at East Grand Terre Island along the Louisiana coast in the wake of the BP Deepwater Horizon rig explosion. Retired Coast Guard Adm. Thad Allen, the federal government's point man on the disaster, said Sunday, Sept. 19, 2010, BP's well "is effectively dead." A permanent cement plug sealed BP's well nearly 2.5 miles below the sea floor in the Gulf of Mexico, five agonizing months after an explosion sank a drilling rig and led to the worst offshore oil spill in U.S. history.
