From The Greeley Tribune:

About 178 barrels of crude oil, or roughly 7,500 gallons, has spilled east-southeast of Windsor and is affecting the Poudre River, state officials said Friday.

The operator, Noble Energy, discovered the spill Friday and reported it to the Colorado Department of Natural Resources, said Todd Hartman, the department’s communications director.

Noble reported a storage tank affected by spring flood waters released its contents. The release appears to be due to floodwaters undercutting a bank, causing the tank to drop downward and damaging a valve, allowing oil to escape from a broken valve. The well associated with the tank is shut in, and a second tank nearby appears unaffected.

Standing water with some hydrocarbons remains in one low-lying area near the tank, Hartman said.

Vegetation is stained for about one-quarter mile downstream of the site.

Noble had environmental response personnel on site Friday afternoon.

A vacuum truck was removing standing water and response personnel were sampling soils.

The oil storage tank sits next to a field east of Weld County Road 23, on the north side of the Poudre River. The tank sits about 200 feet from the river, up a hill. A lot of flood damage was visible in the area, with washed out and eroded river banks and debris still in the water.

Hartman said water quality staff from the Colorado Department of Public Health and Environment also were at the spill site Friday but have not discovered any impact on drinking water.
