Troopers discovered that both of the semi's 100-gallon capacity fuel tanks had ruptured in the crash and were spilling fuel into the river. Weber County hazardous materials workers were dispatched for cleanup.
Scott Braeden, an environmental scientist with the Weber-Morgan Health Department, said the fuel tanks were completely empty when the truck was finally fished out of the river. However, the amount of fuel that flowed downstream was limited because the water was frozen and much of the spill stayed on top of the ice.
According to Braeden, a crew managed to "vacuum" up the fuel from on top of the ice. Crews also deployed absorbent mats and "containment booms" described as long cylinders that can soak up petroleum products to catch the spill before it got too far down stream.
Braeden did not know exactly how much fuel spilled because it was unclear how full the tanks were at the time of the accident.
The truck also spilled a shipment of metal brackets into the water. Braeden said the brackets were still on the floor of the river Friday night, though authorities planned to require their removal.
The driver of the truck was transported to Ogden Regional Hospital to be checked out.
The cause of the accident was under investigation.
