>>> it's a sickening sight in the waters off the shore of louisiana. more oil, and now more containment boom and cleanup crews, just as they are still trying to recover from last year's catastrophic spill and environmental disaster . tonight louisiana state officials say they have traced the spill to an oil company based in houston, texas, but the company's offshore partner says they're surprised the oil has been traced to one of their closed wells because they said they were only aware of a discharge of five gallons of oil. they had been working on permanently plugging a well when the spill took place. the slick has now spread over a 30-mile area. they say they will pay for the cleanup.
