The refinery produces gasoline, diesel fuel and asphalt from Canadian oil sands. It can produce up to 98,000 barrels per day.
In a statement to CPR, spokeswoman Nicole Fisher said that Suncor's "Commerce City Refinery experienced a power failure which resulted in an operational upset."
"As a result of this upset a visible emission can be seen coming from the Refinery," the statement read. "We are working to safely stabilize the plant following the power failure."
The statement concludes by noting that air monitoring is underway in the area around the refinery and in the neighboring community.
