They say they’re not sure where the oil came from, but water samples are being taken, and the creek is being watched.

“Our top priorities are ensuring the safety of our team and the community, and protecting the environment. We are taking this situation seriously and have notified the appropriate authorities,” Suncor stated in the letter to residents.

In a response to CBS4, Suncor officials said, in part:

“There is no action required by the community, and no wildlife have been observed in the immediate area at this time. We will provide updates as more information becomes available.”

On Friday, the Colorado Department of Public Health and Environment approved a plan by Suncor to implement operational changes. Those changes were founded by a third-party investigation following numerous violations and emissions exceedances.

“The department’s decision to approve Suncor’s plan came after the department pushed for changes to address concerns with the company’s original submission. The revised submission further protects public health by more directly fixing operational shortcomings,” stated CDPHE in a news release on Friday.
