Since 1995, the Appalachian region has produced about half of the United States' coal. Variations of surface
coal mining techniques in Appalachia include contour, area, high-wall, auger, and
mountaintop removal mining (MTR). The
Office of Surface Mining (OSM) is the federal agency tasked with regulating strip-mining under the
Federal Surface Mining Control and Reclamation Act (SMCRA). According to OSM, "[t]o the extent that low income populations are prevalent in the coalfields, the impacts of mountaintop mining are felt disproportionately by these environmental justice populations". Most local residents are unable to see the extent of the damage that has been caused by surface mining. Geologist Sean P. Bemis investigated claims by local residents that the extent of the damage was not easily visible. In interviews with the research team, former miner Chuck Nelson stated that the extent of the destruction is only clearly visible from a plane. Coalfield resident activist Maria Gunnoe gave a similar account to the researchers, saying "I never realized it was so bad. My first fly-over with South Wings [non-profit aviation organization], and that right there is what really fired me up. When I got off the plane that day, I cried all the way across the tarmac, all the way home..." The
Government Accountability Office (GAO) confirmed this in a 2009 report: There are no official records of the total number of "disturbed acres" that have resulted from surface mining, but geospatial analysis has shown that between 1.05 million and 1.28 million acres of land and more than 500 mountains in West Virginia, Kentucky, Tennessee, and Virginia have been surface mined.
Mountaintop removal One form of surface mining is
mountaintop removal (MTR). This technique can remove as much as 800 to 1000 feet from mountaintops, in order to reach
coal seams not accessible by other
surface mining techniques. This practice was used on a small scale in the 1970s, and became heavily used in the 1990s because of the increased demand for high-grade
low-sulfur coal following passage of the
Clean Air Act Amendments of 1990. The process of MTR begins by the
clearcutting of trees on a chosen mountaintop, which is then blasted with explosives. Next all of the excess soil and rock or "spoil" is moved out; after the mining operation is complete this will be replaced. Once this rock has been disturbed, swelling will take place; the spoil will expand by fifteen to twenty five percent, due to air incorporation and voids. The excess spoil or "
overburden" then is dumped into nearby streams or valleys, a process referred to as a "valley fill". Mountaintop mining and valley fills can lead to large scale landscape changes, which may include: conversion of habitats, fragmentation of forests, and loss of large tracts of forested land. Since the boom in MTR usage, as many as 500 mountaintops have been destroyed and 2000 miles of waterways have been filled. Combustion waste and
fly ash from MTR lend to toxic dusts pollute the surrounding air and have contributed to increased levels of
cancer,
cardiovascular disease,
liver disease, and
kidney disease. In an analysis of health-related quality of life that compared United States residents in counties with and without coal mining, it was reported that residents in counties with coal mining had, "significantly fewer healthy days for both physical and mental health". Lastly, through examination of
mortality rates, county-level
poverty rates, and coal mining within counties of Appalachia, it was identified that coal mining areas of Appalachia experienced higher mortality rates then counties with no coal mining. Within their discussion section it was stated that "coal mining work and occupational silica exposure are both associated with threefold odds of RA." However black lung disease is not the only form of pneumoconiosis that coal workers are exposed to. They also often face exposure to silica dust because of the drilling process. •
Cardiovascular Disease: Epidemiological research has found that environmental
air pollution is strongly associated with increased risks of
cardiovascular diseases, including
coronary artery disease,
heart failure,
stroke, and elevated cardiovascular morbidity and mortality rates. Populations exposed to pollutants such as
fine particulate matter, including PM2.50 and
nitrogen dioxide, faced heightened risks of developing such conditions. Long-term exposure to PM2.5 has been associated with ischemic heart disease, stroke, and increased mortality. Furthermore, in areas where
coal mining are prevalent, residents are often exposed not only to ambient air pollution, but also water contaminated with toxic substances originating from coal mining and processing activities. Furthermore, research done by Finch and Conklin has found that exposure to specific air pollutants is associated with changes to the structure of the heart. Pollutants may induce
cardiac hypertrophy, or the thickening of the heart muscle, thereby increasing the number of contractions required per minute to supply adequate oxygen and nutrients to the body. This response, however, can lead to cardiac overload and contribute to the development of cardiovascular disease. Specifically, exposure to nitrogen dioxide, PM10, and PM2.5 particles have been linked to the enlargement of both the left and right ventricles, which elevates
arterial blood pressure. Environmental impacts Coal surface mining has heavily altered the
hydrological cycle and landscape of Appalachia causing environmental degradation and contributing to
ecosystem damages beyond repair. In addition, it has led to the clearance of over 1 million acres of forests and contributed to the degradation or permanent loss of over 12000 miles of streams crucial to the Appalachian watershed from 1985- 2001. Mountaintop removal has caused the native Appalachian forests to shift into grasslands/shrubland ecosystems. Pericak et al. in their research noticed that this practice has, "lowered the local topographic complexity, lowered the average slope by nearly 10°, and created novel plateau-like landscapes." Increased salinity and metal contamination of the Appalachian streams have led to toxic effects of fish and bird species. These wastes are disposed in "valley fills" which have collapsed and produced heavy flash floods in Appalachia. The Environmental Protection Agency approximates that between 1985 and 2001, over 700 miles worth of streams in the Appalachians were covered by these "valley fills" due to mountaintop removal coal mining. The practice of mountaintop removal itself causes harm to the environment, however there are other hidden polluting factors within the process. One of these is the transportation of the coal to the plants that it will be refined in. Operation of large transportation vehicles use fossil fuels as a gas source which releases CO2 into the air. At the same time, the transportation of the coal further spreads the particulate matter from the mining process into nearby towns. Anejia et al. found that, "...coal trucks frequently travel through communities located in steeply sided valleys, or hollows, where homes are situated very close to the narrow roads. Some communities experience up to hundreds of truck trips a day. Coal trucks emit dust directly from their tires, bodies, and beds."
Social and economic impacts Appalachia has historically been one of the most
impoverished regions of the country. However, work done by Black and Sanders shows that between 1970 and 1980 the increase in coal production substantially boosted the pay of low skilled workers in Appalachia and likely caused a decrease in
income inequality. Although coal mining industries are often associated with increased jobs and economic growth, this association does not hold for Appalachia, where two-thirds of the counties have higher levels of
unemployment than the nation and per capita personal wages falling 20% lower than the nation. More specifically, in Hendryx and Zullig's comparative analysis of Appalachia counties, those with coal mining had greater economic disparities and more poverty than those without industry. From 2014 to 2015, overall mining employment for Appalachia has dropped by 15.9%. With the decrease in economic opportunities for the people of Appalachia came despair that left many hopeless for their future. This causes diseases of despair such as alcohol and drug overdose (both prescription and illegal), suicide, and alcoholic liver disease. (Marberry & Werner, 2020). Furthermore, it is believed that diseases of despair may be connected to
solastalgia. Solastalgia is a, "psychoterratic illness, which is 'defined as earth-related mental illness where people's mental wellbeing … is threatened by the severing of 'healthy' links between themselves and their home/territory.'" A NASA study states that promises of beneficial post-mining development in the Appalachian region have yet to materialize.
Upper Big Branch disaster On April 5, 2010, there was an
explosion at the Upper Big Branch mine in
Raleigh County, West Virginia, owned by
Massey Energy. The explosion took the life of 29 miners and is labeled the worst accident in the United States since 1970. In 2015 professor Nicole Fabricant wrote, "Because Massey Energy cut corners on safety regulations—in this case, failing to provide appropriate ventilation for methane—the company essentially created the tragedy of Upper Big Branch. The
Mine Safety and Health Administration found that flagrant safety violations contributed to a coal dust explosion. It issued 369 citations in 2011, assessing $10.8 million in penalties."
Marsh Fork Elementary School Protests During the time that this school was in operation the citizens began to have major concerns about how close coal mining operations were to the school. Fabricant stated that, "The school sits next to a coal silo and just 400 feet downslope from an impoundment that holds back billions of gallons of coal slurry." == Law and regulation ==
