EXHIBIT L -RECLAMATION COSTS The information provided in this Exhibit is intended to satisfy the requirements outlined in Section 6.4.12 of the Colorado Mined Land Reclamation Board Construction Material Rules and Regulations: We have selected the phase of the mining that includes the largest area disturbed atone time to calculate the potential reclamation liability. This will occur during Phase 2. Assuming the entire Phase is mined, with no reclamation. Although Phase 3 has larger surface area, this Phase would be mined at a 3:1 slope and therefore at any time during mining, would not hold the greatest liability for reclamation. ^ Phase 1 would be 100% mined and 90% reclaimed. Phase 1 would be completely backfilled to rough finish grade. Phase 1 would require final grading, topsoil placement, seed and mulch. ^ Phase 2 would be 100% mined and 0% reclaimed. Phase 2 would require backfill to rough finish grade (estimated to be 30 feet deep based on bore logs), final grading, topsoil placement, seed and mulch. ^ Phase 3 would be 0% mined and therefore no reclamation is required. ^ The Landscape Sales Yard includes the scale, scale house, access road and landscaping materials. The scale, scale office, and landscape materials are saleable and therefore no cost for reclamation. The foundation for the scale and office will require demolition. The area will require topsoil placement, seed and mulch. ^ Although Phase 3 will not be mined at this stage, the slurry wall surrounding Phase 3 is proposed to be installed prior to exposure of groundwater. Therefore we request the option for 20% bonding of this cost. ^ There is no processing activity proposed at this site, therefore no associated reclamation. Please refer to the attached table for estimates of quantities and associated costs. Hall-Irwin Corporation - ParkerlDersham Sand and Gravel Mine - MLRB 112 Permit Application Exhibit L -1
