Exxon to drain oil from failed pipeline

Exxon Mobil Corp. plans to use vacuum trucks to suck any remaining oil from a failed pipeline near Laurel that spilled an estimated 42,000 gallons of crude into the Yellowstone River.

Geoff Craft is the company's incident commander on the spill. He said Wednesday that the use of the vacuum trucks should prevent any more oil from polluting the scenic waterway.

Montana Department of Environmental Quality deputy director Tom Livers says the work could begin by this weekend and take several days to complete.

The cause of the July 1 pipeline failure remains under investigation.

Hundreds of cleanup workers continue mopping up oil spread over dozens of miles downstream from the spill.

A congressional hearing on the accident is scheduled for Thursday in Washington, D.C.
