An unknown amount of diesel fuel was spilled on the Denali Highway after a tanker truck rolled over.
Alaska State Troopers say 56-year-old Robert Ketzler of Nenana lost control of the vehicle, hit a ditch, and then rolled.
Ketzler was headed towards the Parks Highway in a blue 1999 International Tanker Truck during the time of the incident.
Ketzler reported he was not wearing a seatbelt at the time of the accident.
He was transported to Fairbanks Memorial Hospital with minor injuries.
The Cantwell Fire Department responded to the scene where they were able to stop the leak until it could be pumped into a separate truck.
The Department of Environmental Conservation has been notified and planned to respond to the incident as well.
