Illegally dumped tires catch fire in Pa. coal mine Updated Apr 29, 2021; TREVORTON – A fire in an abandoned mine near Trevorton in Northumberland County might have spread from illegally dumped tires and trash to coal. That is the speculation because sulphur odors have been detected along with those from burning rubber and plastic, Stephen Jeffrey, county public safety director, said Thursday. The Trevorton Fire Co. was dispatched Saturday for a reported brush fire but discovered smoke coming out of the ground, he said. The mine, which reportedly has not been operated since the 1970s, is on county-owned land that is leased to the Anthracite Outdoor Adventure Area.
