If you're visiting Yellowstone during the Holiday, watch out for oil floating down the river.
(Reuters) - A pipeline operated by Exxon Mobil Corp leaked as many as 1,000 barrels of crude oil into the Yellowstone River in Montana and has been shut down, the company said.
Exxon officials said on Sunday there were traces of oil up to 10 miles downriver from the site of what they called a "very unusual" event.
The oil company said it had slowed processing rates at its Billings refinery following the leak but did not expect supply disruptions in the area.
Exxon found the leak from the EMPCo pipeline early on Saturday morning. The pipeline runs only in Montana, from Silver Tip to Billings.
