Description:
This report describes a study of atmospheric emissions from coal refuse piles, abandoned mines, and outcrops. The potential environmental effect of the source was evaluated using source severity (defined as the ratio of the maximum time-averaged ground level concentration of an emission to a hazard factor). Burning of coal piles, impoundments, abandoned mines, and outcrops results in emissions of various pyrolysis and combustion products such as particulates, nitrogen oxides, sulfur oxides, carbon monoxide, hydrogen sulfide, ammonia, polycyclic organic materials (POM), and hydrocarbons, including benzene, toluene, and xylene. Trace elements such as arsenic, boron, and mercury are also emitted.
