210,000 gallons/795,000 liters)
Five times larger than originally estimated.

An Obama aide said that until the cause of the Deepwater Horizon accident is known, it will not allow drilling in new areas, as the president recently proposed.
* Tony Hayward, BP chairman, said the company is fully responsible for the oil spill and will pay all legal claims and cleanup costs.
The Interior Ministry ordered safety inspections on all 30 deepwater drilling platforms and 47 Deepwater production platforms. * May 1 -
The Coast Guard said the leak would affect the Gulf Coast. * May 2 -
Obama visited the Gulf Coast and witnessed the clean-up. U. S.
Officials shut down areas affected by the oil spill within the first 10 days.
BP began drilling a relief well next to a failed well, and the process could take two to three months to complete. * May 5 -
A barge began to drag a 98
Tons of safety room at the leak site.
BP said that one of the three leaks has been closed by capping the valve, but this will not reduce the amount of oil being ejected.
Officials took control of Burns to remove oil from open waters, the first since April 28. * May 6 -
Oil rushes ashore on the chandrero islands off the coast of the state of Luis Anna, part of the Bretton Woods national wildlife sanctuary and an important nesting and breeding area for many birds. * May 7 -
BP engineers use undersea robots to move the sealing chamber on one of the two remaining leaks.
The company gave up its efforts to close a failed blowout preventer valve with an underwater robot.
The fishing ban in federal waters near the Gulf was amended, expanded and extended to May 17. * May 8 -
When the accumulation of crystalline gas forced engineers to delay efforts to put the chamber on the surface of the oil spill and siphon oil, BP's containment dome encountered obstacles.
Suspected "tar ball" from the leak along half
Crown Prince Island, Alabama is a mile long. * May 9 -
BP said it may try to plug the bottom of the sea by pumping materials such as tires and golf into the well under high pressure, a method known as "garbage shooting ".
