THE PROCESS In mountaintop removal mining, the targeted land is clear-cut of all trees, which are usually sold to Timber companies.1 The topsoil is removed and set aside for later reclamation.2 Miners then use explosives to blast away the land, Overburden (the rock and Subsoil that lies above a coal seam), exposing the Coal . The overburden is pushed into a nearby valley or hollow, creating a pile below called ''valley fill''. A Dragline Excavator removes the coal, and it is transported to a processing plant and washed. Millions of gallons of waste from coal processing, called ''sludge'' or ''slurry'' , are often stored nearby in open pools held back by earthen dams. Upon completion of coal removal from a mountain, the mining operator replaces soil on the stripped site and seeds it for Revegetation . Because coal usually exists in multiple seams separated by rock, miners can repeat the blasting process to mine over a dozen seams on a single mountain, lowering the mountain's height each time, sometimes hundreds of feet.3 Kentucky and West Virginia, the two leading coal-producing states in Appalachia , each use about 1000 metric tons of explosives per day for surface mining.4 The EPA estimates that of Appalachian forests will be mined using mountaintop removal by 2012.5 ECONOMICS Just over half the electricity in the United States is produced by coal-fired power plants. Mountaintop removal accounted for less than 5% of U.S. coal production as of 2001. In some areas, however, the percentage is higher. Mountaintop removal provided 30% of the coal mined in West Virginia in 2006.J. O. Britton and others, ''West Virginia'', Mining Engineering, May 2007, p.125. Mountaintop removal and similar forms of Surface Mining allow easy access to coal in certain geologic areas. Increased demand for coal sparked by the 1973 and 1979 Energy Crises first triggered widespread use of MTR. The mining method's prevalence expanded further in the 1990s to retrieve relatively low- Sulfur coal, which became desirable as a result of amendments to the Clean Air Act that tightened emissions limits on high-sulfur coal processing.6 Unlike more traditional Underground Mining , which usually requires hundreds of miners to extract minerals, mountaintop removal is lucrative for coal companies because the use of explosives and large machinery greatly reduces the need for workers. The industry lost 10,000 jobs from 1990 to 1997, as MTR became widespread.7 However, with fewer miners connected to MTR, Labor Unions have less representation, and the United Mine Workers Of America have charged that anti-union practices are often associated with MTR. They have also called for additional legal measures to protect communities from the degradation and destruction that results from nearby blasting.8 The coal industry asserts that surface mining techniques, such as mountaintop removal, are safer for miners than sending miners underground.9 In many locations, proponents argue, mountaintop removal is the most cost-effective method of extracting coal for the mine operator. The counties that host MTR are often the poorest in Appalachia. For instance, in McDowell County, West Virginia , which produces the most coal in the state, over 37% of residents live below the Poverty Line .10 In Kentucky, counties with coal mining have economies no better than adjoining counties where no mining occurs.11 LEGISLATION Coal companies also must obtain permits to deposit valley fill into streams. On four occasions, federal courts have ruled issuance of these permits in violation of the Clean Water Act . 13 14 The Bush Administration appealed and overturned one of these rulings in 2003 because the Act does not explicitly define "fill material"; under the administration, the EPA and Army Corps of Engineers changed a rule to include mining debris in the definition of "fill material." 15 Massey Energy Company is currently appealing a 2007 ruling, and has been allowed to continue mining in the meantime because "most of the substantial harm has already occurred," according to the judge.16 If passed, a bill in the House Of Representatives , H.R. 2169, would specify that coal mining waste does not constitute fill material,17 in effect disallowing valley fills. A federal judge has also ruled that using settling ponds to remove mining waste from streams violates the Clean Water Act. He also declared that the Army Corps of Engineers has no authority to issue permits allowing discharge of pollutants into such in-stream settling ponds, which are often built just below valley fills. CRITICISM Critics contend that mountaintop removal is a disastrous practice that benefits a small number of corporations at the expense of " 18 by New York based VBS TV, highlighting the impact on the community as well as the biodiversity impacts created by this form of mining. A U.S. Environmental Protection Agency Environmental Impact Statement finds that streams near valley fills from mountaintop removal contain high levels of minerals in the water and decreased aquatic Biodiversity .19 The statement also estimates that of Appalachian streams were buried by valley fills from 1985 to 2001.20 In common with other methods of coal mining, processing the coal mined by mountaintop removal generates waste Slurry (also called ''coal sludge''), which is usually stored behind a dam on-site. Many Coal Slurry Impoundment s in West Virginia exceed 500 million gallons in volume, and some, including the Brushy Fork impoundment in Raleigh County , exceed 7 billion gallons.21 Such impoundments can be hundreds of feet high and have close proximity to schools or private residences.22 The most controversial sludge dam at present sits above Marsh Fork Elementary School. The sludge pond is permitted to hold 2.8 billion gallons of toxic sludge, and is 21 times larger than the pond which killed 125 people in the Buffalo Creek Flood . 23 Kentucky's Martin County Sludge Spill occurred after midnight on October 11 , 2000 , when a coal sludge impoundment broke through into an underground mine below, propelling 306 million gallons of sludge down two tributaries of the Tug Fork River . The spill polluted hundreds of miles of waterways, contaminated the water supply for over 27,000 residents, and killed all aquatic life in Coldwater Fork and Wolf Creek. Blasting at a mountaintop removal mine expels coal dust and fly-rock into the air, which can then disturb or settle onto private property nearby. This dust contains sulfur compounds, which corrodes structures and tombstones and is a health hazard. 24 Although MTR sites are usually reclaimed after mining is complete, reclamation has traditionally focused on stabilizing rock and controlling erosion, but not Reforesting the area with trees.25 Quick-growing, Non-native Grasses , planted to quickly provide vegetation on a site, compete with tree seedlings, and trees have difficulty establishing root systems in compacted backfill.26 Consequently, Biodiversity suffers in a region of the United States with numerous Endemic Species .27 Erosion also increases, which can intensify Flooding . In the Eastern United States, the Appalachian Regional Reforestation Initiative works to promote the use of trees in mining reclamation.28 Advocates of mountaintop removal point out that once the areas are reclaimed as mandated by law, the technique provides valuable flat land suitable for many uses in a region where flat land is at a premium. They also maintain that the new growth on reclaimed mountaintop mined areas is better able to support populations of game animals.J.S.
