Revised 11/15/81 <br /> sewage treatment plant, slope conveyor, and water tank. CF&I Steel <br /> Corporation plans to salvage all iron and steel scrap which is of value <br /> within these structures and remove them from the minesite. All material <br /> which cannot be salvaged or does not have value will also be removed <br /> from the minesite and disposed of in the appropriate manner. Materials <br /> such as concrete, insulation, and other general waste material will be <br /> hauled to the local landfill or disposed of onsite in an environmentally <br /> safe manner. . <br /> Other facilities and structures that will be removed include the <br /> railroad spur which is located off of the main line track. The railroad <br /> spur will be dismantled and removed after the mine has been closed and <br /> it is not needed for other uses. The rail and other scrap iron material <br /> will be removed and salvaged. Ties, ballast, and subgrade material will <br /> also be removed from the site and disposed of appropriately. <br /> The sediment control structures and surface drainage ditches which are <br /> required to route surface water to the sediment ponds will be left <br /> intact during the revegetation period. After the area has been <br /> revegetated to pre-mining conditions, CF&I Steel Corporation plans to <br /> remove the sediment ponds only if they are determined to create a safety <br /> hazard or have a negative impact on the environmental resources. <br /> The reclamation of .the coal processing waste disposal banks will consist <br /> of covering the material with non-toxic material as is available at the <br /> minesite. Several detailed studies of the coal processing waste <br /> material indicate that this material is not acid-forming nor toxic. <br /> Therefore, it is not required to cover this material with soil material <br /> other than to provide a plant growth medium. <br /> A detailed cost estimate of the reclamation plan included in this permit <br /> application has been determined by CF&I Steel Corporation. This plan is <br /> located in Rule 3, Performance Bond Requirements. Supporting <br /> calculations for the bond and reclamation cost estimate are located in <br /> Exhibit 17 , Bond Calculation. <br /> 2.05-28 <br />
