This report "The Effects of Mountaintop Mines and Valley Fills on Aquatic Ecosystems of the Central Appalachian Coalfields," reviews the state of the science on the ecological impacts of Mountaintop Mines and Valley Fills (MTM-VF) on streams in the Central Appalachian Coal Basin. This basin covers about 12 million acres in West Virginia, Kentucky, Virginia, and Tennessee. The draft report reviews literature relevant to evaluating five potential consequences of MTM-VF operations: 1) impacts on headwater streams; 2) impacts on downstream water quality; 3) impacts on stream ecosystems; 4) the cumulative impacts of multiple mining operations; and 5) effectiveness of mining reclamation and mitigation. The report did not review the impacts of MTM-VF on cultural and aesthetic resources or human health. EPA used two primary sources of information for the evaluation: (1) the peer reviewed, published literature and (2) the Programmatic Environmental Impact Statement (PEIS) on Mountaintop Mining/Valley Fills in Appalachia and its associated appendices prepared in draft in 2003 and finalized in 2005.
