RECLAMATION COSTS <br />EXHIBIT L <br />The worst case reclamation scenario will occur when Phase 3 is mined out. The following shows <br />the required activities necessary to reclaim the site at this point: <br />1. Dewatering the pit in order to backfill, topsoil, and seed disturbed areas. <br />2. Backfill Phase 3 slopes to 3H:1V <br />3. Place and grade topsoil in Phases 3 and the haul roads and processing site to the west. <br />4. Seeding of all appropriate areas. Wetland seeding to be placed in the wetland fringes in Phase <br />3 from 5 feet below the water line to 4 feet above on the slopes. Dryland seed to be placed on <br />all of the slopes above the wetland area in Phase 3, the flats in Phases 3, and the haul roads <br />and processing site. All seeding will be accompanied by mulching and crimping as described <br />in the reclamation plan. <br />Worst case reclamation costs for this scenario are given below: <br />Task Description Cost <br />1 Dewater disturbed area (306 acre-ft @ $58/acre-ft) $ 16,129 <br />2 Backfill Phase 3 (41,446 CY @ $0.60/CY) $ 24,868 <br /> <br />3 Place and grade topsoil in Phase 3 along with haul <br />roads (2,420 CY @ $0.95/CY) <br />$ 2,299 <br /> <br />4 Seed and mulch dryland areas in Phase 3 along with <br />haul roads (1.0 acres @ $750/acre) <br />$ 750 <br /> <br />5 Seed and mulch wetland fringe along lake in Phase 3 <br />(0.4 acres @ $850/acre) <br />$ 340 <br />Tota I 1 $ 44,386 <br />DRMS Costs (21%) $ 9,321 <br />Total (including DRMS costs) $ 53,707 <br />Gehrman Pit October 09 L-1
