Exhibit L <br /> 35. The list on page L-1 does not account for Area 2. Cost should include dewatering, <br /> backfill, and seeding of Area 2 as well. <br /> a. Clarify if the 800 ft. to place topsoil is accurate for Area 2 as well. If not <br /> provide the distances for each work area <br /> b. Speck the distance to place overburden in Area 2 <br /> Dewatering of Area 2 is not in Exhibit L as the amount of water that must be dewatered at the <br /> very end of Area 1 is greater to or equal to any combination of Area 1 and Area 2 dewatering. <br /> Area 2 will have a peak dewatering requirement of roughly 22 acre-ft. This volume will be filled <br /> by backfill prior to Area 1 reaching its full mining scale. At full mining scale, Area 1 would <br /> require the dewatering of 269 acre-ft to allow for topsoiling and seeding on the slopes. This <br /> means that the time of greatest dewatering at 23.25 West Pit is after backfilling is completed in <br /> Area 2. <br /> A topsoil haul distance(1100 feet) from Area 1 to Area 2 has been added to the list in Exhibit L. <br /> Overburden backfilling in Area 2 will be complete at the time of the bond scenario as it occurs <br /> when Area 1 is finished mining. Thus Area 2 backfilling is not included in the bond cost. <br /> Topsoiling and revegetating has been expanded to 10 acres to incorporate final topsoiling and <br /> revegetation work in both Area 1 and Area 2. <br /> 36. Table L-1. <br /> a. Table needs to include costs for Area 1 and Area 2 (list separately where <br /> possible) <br /> b. Dewatering task is only for Area 1. What is the starting ac.ft. that needs <br /> dewatered and the inflow rates for both Area 1 and Area 2 (individually). <br /> Inflow rates may also be provided in Exhibit G <br /> c. Include a cost and units for overburden placement to backfill Area 2. <br /> d. Describe reclamation task such as topsoil, seedbed prep, seeding and mulching <br /> for each Area. <br /> Given that Area 2 will be entirely back-filled, the Operator may wish to have a stockpile location <br /> in Area 2 to decrease bonding for hauling material from the west side of Area 1 to Area 2. <br /> Table L-1 has been updated in line with the responses to Item 35. See the revised Exhibit L. <br /> Exhibit N <br /> 37. 8c-states the use of concrete/rubble for backfill however there is no mention of <br /> importation of material in the mining or reclamation plans. <br /> See the revised Exhibit D regarding the import of materials. <br /> 23 114 West Pit 7 <br /> October 2020 , , — <br />
