Mountaintop Mining: Background on Current Controversies

Description: Mountaintop removal mining involves removing the top of a mountain in order to recover the coal seams contained there. This practice occurs in several Appalachian states. It creates an immense quantity of excess spoil (dirt and rock that previously composed the mountaintop), which is typically placed in valley fills on the sides of the former mountains, burying streams that flow through the valleys. Critics say that, as a result of valley fills, stream water quality and the aquatic and wildlife habitat that streams support are destroyed by tons of rocks and dirt. The mining industry argues that mountaintop mining is essential to conducting surface coal mining in the Appalachian region and that surface coal mining would not be economically feasible there if producers were restricted from using valleys for the disposal of mining overburden. Mountaintop mining is regulated under several laws, including the Clean Water Act and the Surface Mining Control and Reclamation Act. This report provides background on regulatory requirements, controversies, and legal challenges to regulation of mountaintop mining. Congressional attention to these issues, including legislation that would restrict the practice (H.R. 1310, the Clean Water Protection Act, and S. 696, the Appalachia Restoration Act), also is discussed.
