ENVIRONMENTAL PROBLEMS WITH COAL, OIL, AND GAS

Coal is often washed just outside the mine to remove foreign materials, and the waste material from this washing is piled up in unsightly heaps. In 1983 there were 177,000 acres of these waste banks in the United States, the great majority in Appalachia. Many of these waste banks catch fire and burn, serving as a source of air pollution.
