MANILA -- Officials say it could take two to four weeks to clean up a hazardous material spill along a highway in Daggett County.
The Utah Highway Patrol says the spill occurred Thursday on state Route 44 near Manila when a tractor-trailer hauling 12 large containers of chlorite solution tipped over and rolled down a ravine.
UHP Lt. Steve Winward said that up to 3,600 gallons of the material spilled from the containers.
He says an unknown amount of the chlorite solution leaked into a stream that feeds into Flaming Gorge Reservoir, and it could affect fish there.
Crews will remove soil that became saturated with the material.
The driver told authorities that the crash occurred when he swerved to avoid an animal on the roadway.
