Crews on land and sea Saturday worked to clean up nearly 50,000 gallons of crude oil that spilled onto the ground and into Fidalgo Bay after the blowout of a pump at a refinery.

The spilled oil flowed along railroad tracks a few hundred yards and through a culvert, said Lee Reagin, the Texaco refinery's supervisor of human resources.Only a small fraction, about 3,100 gallons, entered Fidalgo Bay, the Coast Guard said.

The garbage can-size chunk of five-eighth-inch steel casing was hurled about 60 feet, and oil sprayed as far as 50 yards, said Jack Brian, assistant manager at the Texaco refinery.
