Firefighters were called on Sunday afternoon, May 10 to the Delaware County Solid Waste Management Center in Walton, where a smoky fire was burning in a pile of construction and demolition debris.
The "C & D" pile contains wood, plastic and other debris that is not processed through the county's composting plant.
James Olmstead, a deputy coordinator and investigator with the Delaware County Department of Emergency Services, said the fire was reported at 12:47 p.m. and had likely been brewing for some time.
"There was probably something in there that heated up over the years and made its way to the top," he said.
Olmstead said firefighters had trouble getting water to the scene, and eventually quenched the flames with foam. He said there was no damage to anything other than the C & D pile.
Firefighters from Walton, Delhi, Franklin, Trout Creek, Treadwell and Downsville fought the fire.
