On April 21, 2026, at about 11 AM, the EPA was notified of the release of an unknown amount of crude oil from an underground pipeline operated by Plains Pipeline LP in Woodward County, OK. Oil discharge impacted soil and a nearby tributary that leads to Ewers Creek. The Responsible Party investigated and isolated the leak, and conducted oil recovery operations using absorbent boom, drum skimmers and underflow dams to contain the discharge in the waterway.

The Responsible Party has transitioned into the remediation phase under the Oklahoma Corporation Commission for any remaining oil, impacted soil and  boom maintenance in the waterway. As the lead federal agency in the inland zone, EPA is coordinating closely with the Oklahoma Corporation Commission, Pipeline and Hazardous Materials Safety Administration, and the US Fish and Wildlife Service.
