NRC#: 1344974

On August 19, 2022, the National Park Service (NPS) reported a discharge of gasoline from a tanker pup trailer on Highway 191, 16.5 miles north of West Yellowstone, Montana. The spill location is located in Yellowstone National Park, in the State of Wyoming.  The incident occurred in the early morning, around 4 am, during a routine fuel delivery run.  The pup trailer, carrying 4,800 gallons of gasoline rolled and lost the entire capacity of the load. No injuries or fire were reported from the incident. 


The West Yellowstone Fire Department, NPS personnel, and contractors for the Responsible Party responded to the scene immediately. On Site personnel, quickly began counter measures and containment. Product from the trailer did enter the western wetland adjacent to the highway. The wetland feeds directly into Grayling Creek, with potential down stream impacts to the State of Montana.   There has been no discharge of gasoline observed into Grayling Creek, only into the wetland area.


On August 19, 2022 U.S. EPA Region 8  deployed a Federal On-Scene Coordinator and a support contractor to the incident. EPA staff arrived on Site on August 20, 2022 to provide technical direction, assessment, stakeholder coordination,  and direction/oversight of the clean up operations.
