BP has acknowledged its estimates of the amount of oil leaking into the Gulf were too low. On Thursday, BP said it’s now capturing 5,000 barrels of oil a day from the leaking pipe — the same amount it had previously said was leaking every day. The Environmental Protection Agency, meanwhile, has ordered BP to use a new chemical dispersant to break up the oil leaking into the Gulf, citing concerns around the initial dispersants’ effect on marine life.
