All mining and processing equipment will be portable and <br /> founded on concrete footings or blocks. Under a closure scenario, the equipment would <br /> be hauled to a heavy equipment auction for sale, and the value would more than cover <br /> cost of removal. The underlying foundations could be reclaimed as follows: <br /> • Footings would be broken with a rock-breaker mounted on an excavator and <br /> the rubble buried in place beneath three feet of cover material <br /> • Concrete blocks would be hauled to a stockpile on-site and sold <br /> The only anticipated rubble will be the foundations of the processing equipment as shown <br /> in Table 1. This rubble will be left in place and buried with approximately 3 feet of cover <br /> material, which is accounted for in the cost estimate provided in Attachments 5 and 6. <br /> As clarified in Exhibit E, the building where the batch plant will be housed, along with <br /> offices and storage will remain in place along with its floor and foundation. <br /> Response to Comments 46 d and e <br /> In the original application and Attachments 5 and 6, the costs for each phase for the <br /> earthworks are shown. LRM plans to perform concurrent reclamation during the mining <br /> of each phase. However,the cost estimate assumes that no reclamation is performed until <br /> the end of each mining phase. This provides a layer of conservatism in the cost estimate. <br /> Additionally, the French drain system would be installed as part of the placement of the <br /> liner. Therefore, only the remaining portion of the drain would require installation under <br /> a default scenario. The general cross section and lengths reported in Sheets 1 and 2 of <br /> Exhibit G (as revised) provides the general quantities for installation of the drain. <br /> Compacted backfill is provided in Attachments 5 and 6, which also provides an estimated <br /> reclamation cost. <br /> Response to Comments 46 f <br /> The plan calls for placement of compacted fill and drain system along the highwall. <br /> Therefore, regrading of the highwall is not anticipated with the proposed mine plan as it <br /> would not allow construction of the compacted liner. The lengths and volumetrics of the <br /> compacted backfill liner are provided in Attachment 6 (BoMag Compacted backfill). <br /> Response to DRMS comments T E L E S T O <br />
