RECLAMATION COSTS EXHIBIT L <br />The worst case reclamation scenario will occur at the end of Mining Area 4. There will be the <br />largest amount of pit floor, plant area, internal roads and inslopes to reclaim to rangeland. These <br />areas are determined below: <br />Area needing topsoiling: <br />Plant area and stockpiles: 5.7 acres <br />Final slopes: 3.7 acres <br />Open Pit floor: 7.5 acres <br />Internal Roads: 4.4 acres <br />Total area = 21.3 acres <br />Area needing soil preparation, reseeding, mulching <br />The 21.3 acres from above + 3.96 acres of the topsoil stockpile = 24.99 acres = 25.0 acres. <br />The office, shop, and other minor structures in the office /shop area will remain for commercial <br />use after the mine is closed. The access road will remain for access to the upper terrace. <br />These reclamation areas will be the furthest from the topsoil stockpile located in the southwest <br />corner of the permit area. Figure L -1 shows the assumptions used in calculating this worst case <br />reclamation cost and the work needed to reclaim the site. <br />Worst case reclamation costs for this scenario are shown in Table L -1 below: <br />Uncompahgre Pit, February 2013 L -1 <br />
