Oil spill grows, with little success stopping flow

VENICE, La. — BP's chairman defended his company's safety record and said Sunday that "a failed piece of equipment" was to blame for a massive oil spill along the Gulf Coast, where President Barack Obama was headed for a firsthand update on the slick creeping toward American shores.

BP PLC chairman Lamar McKay told ABC's "This Week" that he can't say when the well a mile beneath the sea might be plugged. But he said he believes a dome that could be placed over the well is expected to be deployed in six to eight days.

BP spokesman Bill Salvin said McKay was talking about the blowout preventer as the failed equipment that caused the April 20 explosion of the Deepwater Horizon rig, which killed 11 people. The blowout preventer typically activates after a blast or other event to cut off any oil that may spill.

The cause of the blast remains undetermined, and Salvin said "we're not ruling anything out."

The Coast Guard and BP have said it's nearly impossible to know exactly how much oil has gushed since the blast, though it has been roughly estimated the well was spewing at least 200,000 gallons a day.

Even at that rate, the spill should eclipse the 1989 Exxon Valdez incident as the worst U.S. oil disaster in history in a matter of weeks. But a growing number of experts warned that the situation may already be much worse.

The oil slick over the water's surface appeared to triple in size over the past two days, which could indicate an increase in the rate oil is pouring from the well, according to one analysis of images collected from satellites and reviewed by the University of Miami. While it's hard to judge the volume of oil by satellite because of depth, images do indicate growth, experts said.

"The spill and the spreading is getting so much faster and expanding much quicker than they estimated," said Hans Graber, executive director of the university's Center for Southeastern Tropical Advanced Remote Sensing.

In an exploration plan and environmental impact analysis filed with the federal government in February 2009, BP said it had the capability to handle a "worst-case scenario" at the site, which the document described as a leak of 162,000 barrels per day from an uncontrolled blowout — 6.8 million gallons each day.

Oil industry experts and officials are reluctant to describe what, exactly, a worst-case scenario would look like. But if the oil gets into the Gulf Stream and carries it to the beaches of Florida — and potentially loops around the state's southern tip and up the eastern seaboard — several experts said it stands to be an environmental and economic disaster of epic proportions.

"It will be on the East Coast of Florida in almost no time," Graber said. "I don't think we can prevent that. It's more of a question of when rather than if."
