Flames were spotted at Basin Propane in Vernal at approximately 10:30 a.m. Due to the gas plant's potentially-explosive atmosphere, authorities evacuated everyone within a half-mile radius. Highway 40, which runs just a few hundred feet away from the plant, was also closed while firefighters battled the blaze.
A nearby school, Naples Elementary, still held classes because it wasn't in the evacuation zone.
By 2:00 p.m. firefighters had the fire under control and the evacuation was lifted. However, firefighters continued to look for hot spots to prevent the fire from re-igniting. Some power outages were also reported in the area around the plant.
The cause of the fire was not immediately known.
