Oil cap kept shut despite seep near ruptured well

NEW ORLEANS (AP) — The federal government Monday allowed BP to keep the cap shut tight on its busted Gulf of Mexico oil well for another day despite a seep in the sea floor after the company promised to watch closely for signs of new leaks underground.

The Obama administration's point man for the spill, retired Coast Guard Adm. Thad Allen, said early Monday that government scientists had gotten the answers they wanted about how BP is monitoring the seabed around the mile-deep well, which has stopped gushing oil into the water since the experimental cap was closed Thursday.

Late Sunday, Allen said a seep was detected near the ruptured oil well and demanded in a sharply worded letter that BP step up monitoring of the ocean floor. Allen didn't say what was coming from the seep. White House energy adviser Carol Browner told the CBS "Early Show" the seep was found less than two miles from the well site.

The concern all along - since pressure readings on the cap weren't as high as expected - was a leak elsewhere in the well bore, meaning the cap may have to be reopened to prevent the environmental disaster from becoming even worse and harder to fix. An underground leak could let oil and gas escape uncontrolled through bedrock and mud.

"When seeps are detected, you are directed to marshal resources, quickly investigate, and report findings to the government in no more than four hours. I direct you to provide me a written procedure for opening the choke valve as quickly as possible without damaging the well should hydrocarbon seepage near the well head be confirmed," Allen said in a letter to BP Managing Director Bob Dudley.
