Cleanup Crews Still at Work on Dam Oil SpillStaff
The News Tribune, December 28, 2009
Emergency response teams from the Army Corps of Engineers, Environmental Protection Agency and Washington Department of Ecology spent Thursday containing and cleaning up about 3,250 gallons of light mineral-type oil that leaked from a spare transformer at The Dalles Lock and Dam on the Columbia River near The Dalles.
A small amount of oil spilled into the Columbia River, according to the Corps. Aircraft and boat crews did not detect any oil that escaped the immediate area of the dam, and crews also were working to prevent oil that was leaking into the dam's ice and trash sluiceway from reaching the Columbia River.
Crews also removed removed contaminated soil from around the containment facility where the spare transformers are stored.
An investigation was launched to determine why the oil containment systems surrounding the transformers failed.
