Site Location:
Skiatook, OK 74070
NRC#: 1390235

On January 29, 2024, at 1:00 PM, the EPA was notified by the National Response Center (NRC) of a crude oil spill of an unknown quantity from an unverified location two miles north of Skiatook, Oklahoma. Skiatook is in Osage and Tulsa Counties. According to the NRC, the spill is estimated to be one mile long and traveling along a ditch east of Highway 11; an odor was reported as well. The ditch is approximately 900 ft from Bird Creek which leads to the Verdigris River approximately 30 miles downstream. EPA was notified by the Department of Interior Regional Environmental Officer that the Site location is in Cherokee Nation Tribal Statistical Area.

Since the spill location is in the Area of Responsibility, EPA is the lead agency. EPA staff and contractors were activated to the site. EPA conducted a Site walk along Highway 11 from East 176th Street N to the Perrier Bridge, covering approximately 5,130 feet. Water from recent rain events was observed along the eastern and western sides of Highway 11, but no sheen, product, or petroleum odor was found in any parts of the drainage pathway.

EPA conducted community air monitoring for Volatile Organic Compounds (VOCs) using a MultiRAE. All air monitoring locations yielded readings below the MultiRAE detection limit. EPA staff demobilized on January 29, 2024.
