Several calls from concerned citizens who saw smoke coming from Box Elder County’s Little Mountain landfill Sunday afternoon had county crews and Tremonton fire department on scene to put out a smoldering fire.
Kevin Potter, chief deputy sheriff for the county, said the fire apparently started in a pile of biodiesel waste dropped off Friday from Washakie Renewal Energy out of Plymouth. The regular routine is to spread out that waste to dry, Potter said, but on Friday the shipment was left in a heap, which smoldered over the weekend before catching fire. No other waste sites or structures at the landfill were involved.
Potter said the waste from the bio diesel plant is all natural, consisting mostly of old cooking oil.
