Diesel fuel and hydraulic oil are leaking into the San Francisco Bay after powerful winds capsized a freight barge near the Oakland-San Francisco Bay Bridge on Friday.
Authorities said they are preparing to clean a maximum of 4,000 gallons of diesel fuel and 300 gallons of lube oil.
The 112-foot barge named Vengeance has a crane and is under contract with Bay Area Rapid Transit. It is positioned near an underwater rail tunnel that carries BART's commuter lines between San Francisco and Oakland. The barge is used by divers who do underwater anti-corrosion work on the tube.
BART authorities said no crews were working on the barge at the time. The agency's engineers said the tube is not damaged. There are also no reports of damage to wildlife.
The Coast Guard has set aside $50,000 from its oil-spill liability trust fund to use for cleaning up the spill, spokeswoman Petty Officer Sarah Wilson said. A crew placed 3,000 feet of boom around the barge, which will serve as a barrier to minimize the impact of the spill.
