Several areas at the Coal Basin Mine aze designated `pre-law' disturbances. Mining impacted azeas <br />that were not disturbed by a permitted mining operation subsequent to July, 1977 are not required to <br />be reclaimed, or bonded, by the mining company. These areas, known as "Pre-Law" disturbances, <br />were eligible to be reclaimed by the State using monies set aside by the Federal government through <br />the Inactive Mines Program. <br />III. Reclamation Projects <br />Reclamation projects summarized chronologically <br />Mining and Safety report dated August 24, 2007. <br />report is incorporated by this reference. <br />by yeaz aze detailed in a Division of Reclamation, <br />A summary is provided here, and the complete <br />The Division first began work at Coal Basin in the fall of 1994 when a contractor was hired to <br />maintain drainage ditches at the site in anticipation of spring nmoff. Some amount of storm water <br />management was also accomplished at various mine entry areas and at other site facilities. <br />Reclamation construction began in earnest during the summer of 1995, and was substantially <br />completed by the end of 2001. <br />Since the completion of the 2001 construction season, only two reclamation projects have been <br />undertaken at Coal Basin; one funded by the Inactive Mines Program at a pre-law coal refuse pile <br />located near Mine 5, and one funded by a Non-Point Source grant using forfeited bond money as a <br />match. Excepting these two projects, construction at the site between 2002 and 2006 has consisted <br />of maintenance activities. <br />Structural Demolition and Facilities Reclamation <br />The major facilities azea at the Coal Basin Mine were the prepazation plant area, located near the <br />confluence of Coal and Dutch Creeks, and included two warehouses, a wash plant, offices and other <br />assorted structures. The facilities area and portal areas of the mine site were heavily industrialized <br />when the mine was active. Following closure of the mine, a structural demolition company <br />employed by Mid Continent Resources removed all of metallic materials from the entire mine site <br />leaving all non-metallic materials such as asphalt parking areas, concrete foundations, concrete <br />block buildings, and beltline foundations intact. <br />As part of its reclamation activities, Division contractors demolished all asphalt and concrete <br />materials. These materials were hauled to various locations within the mine site, placed against cut <br />slopes and buried. Each disposal area was graded to a geomorphically stable landform designed to <br />route storm water and snow melt drainage safely off the areas. Where available, topsoil was applied <br />and the ground surface was severely roughened. Seed, mulch and fertilizer were applied. <br />Coal Basin Mine Reduced Inspection Frequency September 10, 2007 <br />3 <br />
