Colorado officials are responding to a damaged fuel tank owned by Anadarko Petroleum that has spilled more than 5,000 gallons of crude oil into the South Platte River.
Anadarko, the second-largest operator in the operator in the Denver-Julesburg Basin, has shut down about 10 per cent of its operations, including 250 tank batteries and 670 wells.
In a statement, Anadarko said: "To date, we are aware of two tank batteries that were damaged by flood waters, and have associated light-oil releases. The releases occurred in flood waters associated with the South Platte River and the St. Vrain River, and we have reported them to the Colorado Oil and Gas Conservation Commission, the National Response Center, the U.S. Environmental Protection Agency and the Colorado Department of Public Health and Environment.
"We are actively working under the oversight of these agencies to contain and clean up the releases to the greatest extent possible. We will continue to provide additional information as appropriate," the company added.
