After blasting is digging, which describes the actual removal process of the coal. The coal is extracted using draglines, enormous earth-moving machines, and is then moved off of the now-deformed mountain into a cleaning station, normally located within a nearby river. The coal is washed with chemicals and these chemicals are often mixed into the river water and carried further downstream. Next is dumping waste, which the Bush Administration changed the definition of to include “toxic mining waste” so that coal companies can legally dump debris, or “overburden,” into nearby valleys. The blasted, useless part of the mountain, or “overburden” is deposited into adjacent valleys. These valley fills have buried over 2,000 miles of headwater streams and polluted more. The next step, processing, involves the chemical treatment of the coal prior to its shipment to plants for burning. This creates coal sludge, containing toxic heavy metals like arsenic and mercury. Finally comes reclamation, the part where the companies who engaged in mountaintop removal are supposed to develop the flattened land into something
