Contractors working with the U.S. Coast Guard on Tuesday continued working to stabilize the skeletal remains of the beached and broken barge Davy Crockett.
The 431-foot former Liberty ship has been leaking PCB-tainted oil.
Approximately 10,000 feet of absorbent boom and 3,600 feet of hard boom have been deployed to contain the potential release of oil and protect the shoreline, the Coast Guard said.
The Coast Guard said 127 workers from federal, state and local agencies, as well as cleanup contractors, are responding and have recovered about 1,450 gallons of oil.
Two work barges are on the scene to help.
The boat is on the north bank of the Columbia River between Vancouver and Camas.
