FORT COLLINS, Colo. -- A storage tank damaged by floodwaters dumped 7,500 gallons of crude oil into the Poudre River near Windsor in northern Colorado, slicking vegetation a quarter-mile downstream but apparently not affecting any drinking water, state officials said Friday.
The bank where the storage tank sat next to the river was undercut by the high spring river flows, causing the tank to drop and break a valve, Todd Hartman of the Colorado Department of Natural Resources said in a statement.
The tank released all of its contents, which was 178 barrels of crude oil -- roughly 7,500 gallons -- into the river, Hartman said.
"At this time we know of no drinking-water intakes affected by this spill. The release is not ongoing," he said.
The tank's operator, Noble Energy, discovered the spill Friday and reported it to state officials. Colorado Oil and Gas Conservation Commission officials and state Department of Public Health and Environment water quality officials responded, along with a Noble Energy response team, Hartman said.
Cleanup crews deployed absorbent material at areas where oil could be seen while a vacuum truck removed oily water from a low-lying area near the tank.
A second tank nearby appears to be unaffected.
The site of the spill is southeast of Fort Collins near the Poudre River Trail.
