EXHIBIT L -RECLAMATION COST <br />The information in this Section is intended to satisfy the requirements outlined in Section 6.4.12 <br />of the Colorado Mined Land Reclamation Boazd's Construction Material Rules and Regulations. <br />We request that the Division calculate the bond using the information provided below. <br />For the purpose of this estimate we assumed the worst case scenario for disturbance. The largest <br />azea of mining is Phase 2 (approximately 48 acres). We assumed this would be 100% mined. <br />Due to the limited space for stockpile storage at this site, we assumed that Phase lA, Phase 1B, <br />and the side slopes for Phase 2 would be 90% reclaimed. At this point, the ditch crossings would <br />need to be removed, and approximately 4001f of haul road reclaimed to pre-mining state. At this <br />point, we assumed Phase 3 would be SO% stripped of the overburden and 0% mined or <br />reclaimed. To finish reclamation of the site a 3:1 side slope would need to be created between <br />Phase 2 and 3; 3:1 side lopes from existing grade to top of resource would need to be created in <br />the stripped portion of Phase 3; the entire shoreline above the high water line would require <br />topsoil seeding and mulching; the disturbed area in Phase lA and Phase 3 would require topsoil, <br />seed and mulch; and the cottonwood trees would need to be planted. The slurry wall and <br />relocation of the Bull Seep Ditch is to be done at the beginning of mining and therefore would <br />not require any cost estimate for reclamation. <br />Activity Quantity Units Unit Cost Cost <br />A.
