© Paving Material <br />• 1,800 yds' (eliminated since the road will be retained for the planned industrial <br />postmining land use) <br />Coal and Coal Fines <br />• 3,000 yds' <br />Given that the sub-grade portion of the crusher building will accommodate approximately 450 <br />cubic yards of material, Kerr proposes to dispose of all concrete demolition debris <br />(approximately 40 cubic yards) as well as a portion (400 cubic yards) of the remaining coal and <br />coal fines in this area. The disposal area would then be covered with a minimum of 4-feet of <br />cover material. The remaining volume of coal and coal fines (2,600 cubic yards), along with <br />any swctural steel demolition debris which is not salvaged (maximum of approximately 350 <br />cubic yards), would be disposed of in the alternate upland disposal site. <br />Consequently, the excavation required for solid waste (coal, coal fines, and structural steel <br />demolition debris) disposal in the upland site would be approximately 100' x 200' x 6' deep <br />(0.46 acres) providing capacity for disposal of approximately 3,000 cubic yards and sufficient <br />depth for approximately 4 feet of cover. Topsoil and a portion of the subsoil materials <br />removed from this excavation (approximately 800 to 1,000 cubic yards) would be placed <br />adjacent to the excavation to cover the solid wastes with a minimum of 4-feet of material <br />following placement. The remainder of the excavated material (approximately 2,000 to 2,200 <br />cubic yards) would be utilized as supplemental cover for the Tipple Area. <br />The advantages of the proposed disposal plans are that they; 1) Most effectively utilize the <br />available disposal sites; 2) Place most of the coal and steel demolition debris well above the <br />natural water table to minimize any potential ground water impacts; and 3) Provide needed <br />supplemental cover material for the Tipple Area. <br />Facility Re~radin~ and Drainage Reestablishment <br />With the exception of the addition of 2,000 co 2,200 cubic yards of cover material from the <br />disposal excavation, final grading of the Tipple Area will occur essentially as outlined in the <br />existing approved permit. The supplemental fill material will be selectively utilized to assure <br />adequate cover thicknesses over the crusher building disposal area and as supplemental fill in <br />other areas as required to meet overall regrading objectives. In order co assure that the <br />supplemental cover materials are suitable for reclamation use they will be sampled and analyzed <br />prior to or during excavation of the disposal area. All areas will be regraded to blend with the <br />surrounding terrain and promote effective site drainage. <br />Soil Material Replacement and ReveQetation <br />Soil material replacement and revegetation will occur essentially as outlined in the existing <br />approved permit with the only exception being that any surplus soil material available from the <br />disposal excavation will be utilized to supplement the limited available soil resources in the <br />Tipple Area. <br /> <br />
