The operator of the Keystone pipeline system has finished cleaning up a massive December 2022 oil spill, and the creek affected by it is flowing naturally again, the company and the U.S. Environmental Protection Agency say.
Pipeline operator TC Energy promised to continue monitoring the site along Mill Creek in Washington County, about 150 miles (241 kilometers) northwest of Kansas City. The Canada-based company and the EPA's regional office announced Tuesday that berms that had diverted the creek around the spill site had been removed.
