In 1980, Illinois passed the Surface Coal Mining Land Conservation and Reclamation Act (SCMLCRA), which enabled the state to enforce the permanent regula- tory program under the federal SMCRA. Also in 1980, the State amended the Abandoned Mined Lands and Water Reclamation Act, which established the AMLRC as the agency to administer the federal reclamation funds in Illinois. In 1989, this act was amended to in- clude the reclamation of unreclaimed noncoal sites that contain safety hazards; however, Illinois law restricts the amount of money that can be spent annually on rec- lamation of noncoal sites. Reclamation of lands affected by mining generally is classified into three categories: 1. "Pre-law" coal refers to land mined and abandoned prior to passing the 1977 federal reclamation act. This acreage is eligible for reclamation by the AMLRC. 2. "Post-law" coal refers to land mined after the law was passed. Affected acreage has to be reclaimed by the mine operators. 3. Noncoal refers to other surface mine operations, gen- erally involving the extraction of clay/shale, fluorspar, limestone, industrial sand, and gravel. Most acreage affected by mining in Illinois is from surface coal mining, which since 1963, has affected slightly more than 3,000 to more than 7,000 acres annually (fig. 26). The amount of affected acre- age peaked during the late 1960s, then declined at a rate of about 375 acres annually. The decline parallels a gradual decrease in production of coal produced from surface mines together with an increase in production Figure 27 Land use of reclaimed coal surface mines (1972-1985). from underground mine
