Introduction

Surface mining of coal involves removing soil and rock that overlay coal beds in order to expose the coal. Compared to underground coal mining, surface mining generally costs less, is safer for miners, and usually results in more complete recovery of the coal. However, it also results in much more extensive, though temporary, disturbance of the land surface, which can cause serious environmental problems unless the mined land is carefully reclaimed. The earliest commercial U.S. coal production was in the anthracite region of Pennsylvania. Beginning in 1807, mining became important enough for the federal government to begin keeping statistics on annual production. During those early years of coal mining, reclamation of mine sites and Support facilities was not required by law; however, in the 1930's, as surface mining became more widespread, the idea of mandatory environmental protection and reclamation started to grow. In 1939 West Virginia enacted the first law to regulate the coal mining industry. Similar laws were enacted by Indiana in 1941, Illinois in 1943, and Pennsylvania in 1945. During that period, coal production accelerated greatly and the surface mining of coal became much more prevalent. During World War 11, the demand for coal took priority over environmental concerns, with little consideration for reclaiming the land after mining. Mining pits were not backfilled. Dangerous highwalls were left exposed. Trees and other vegetation were buried by waste material that was simply dumped down the slopes below mines. Topsoil was buried or allowed to wash away. Landslides formed on unstable hillsides. Slopes eroded rapidly because of the lack of vegetation. Polluted water collected in mine pits. Streams became clogged with sediment. Streams and rivers were frequently polluted by acid mine drainage. This vivid image of surface coal mining remains indelible in the minds of most Americans, who remain unfamiliar with modem surface coal mining methods and the changes brought about by the Surface Mining Control and Reclamation Act. After 1945, more coal-producing states instituted regulatory pro- grams. Many required permits for mining. Some included inspections. A few made operators post performance bonds to guarantee reclamation when mining was completed. However, due to the variations in those individual programs, it cost less to produce coal in states with less stringent reclamation requirements, giving operators in those states an economic advantage, generally at the expense of environmental quality. With the 1970's came a surge in the demand for coal resulting from the nation's need for increasing electric power generation and the uncertain supply and increased cost of imported petroleum-based fuels. The resulting increased coal production prompted a series of state laws, primarily in the West, aimed at controlling the environ- mental effects of surface mining. During the late 1960's and early 1970's, North Dakota, Wyoming, Colorado, and Montana passed laws to regulate mining and reclamation. The continuing lack of uniformity among the state surface mining programs and the increase in unreclaimed land and associated pollution of water and other resources caused a growing demand for nationwide regulation of surface coal mining, both to remove the economic inequities and to is sure an acceptable standard of reclamation. After many years of debate, Congress passed the Surface Mining Control and Reclamation Act (SMCRA), which was signed into law August 3, 1977. The Act established a coordinated effort between the states and the federal government to prevent the abuses that had characterized surface coal mining in the past. The law also applied to surface disturbances created by underground coal mining.
