On January 27, 2025, at approximately 8:17 AM, the U.S. Environmental Protection Agency (EPA) was notified by the National Response Center (NRC) of a release of sodium hydroxide and diesel into the atmosphere and on the ground from an overturned tanker truck in Catoosa, Oklahoma, between E Tower Rd and Highway 266. Upon further investigation, the Tulsa Fire Department informed EPA that the tanker was carrying phosphoric acid, not sodium hydroxide as previously reported.  

The Verdigris Hazmat Team, Verdigris Fire Department, and the Tulsa Fire Department responded to the incident. The EPA On Scene Coordinator (OSC) and technical assistance contractor were activated to monitor the incident. 

On January 27, 2025, by 6:00 PM, the remaining phosphoric acid was transferred into another tanker. The tanker with the transferred acid then departed the site. Two large tow trucks with boom arms were used to disconnect the freightliner from the trailer and place them upright.  Additionally, a neutralizer was placed on the contaminated soil and absorbent pads were used to remove pooled diesel. An absorbent boom was also placed around the contaminated soil in the event of rain.  

On the morning of January 29, 2025, the contaminated soil was removed. 

The EPA conducted air monitoring for Volatile Organic Compounds (VOCs) and acids in the community. EPA found no exceedances for VOC’s or acids present in the atmosphere at the source location.
