6.4.5 Exhibit E — Reclamation Plan <br />Maximum stockpile occurring at any one time <br />Topsoil Replacement <br />Stockpiled topsoil will be placed to a minimum depth of 1.0 ft. on all affected <br />areas above the normal pool elevation of the reservoir. The total area to undergo <br />overburden soil replacement is 14 acres and the total topsoil replacement volume <br />is approximately 20,000 yd . This includes the edges of the reservoir and all oil <br />and gas operations areas where backfilling occurred. Topsoil replacement will <br />occur sequentially just after backfilled overburden placement wherever possible <br />to allow for mining under topsoil and overburden stockpiles. <br />Seeding and Fertilizing <br />Currently, the entire pit area is used for dryland pasture and is over -grazed. <br />The proposed seeding areas are shown on Exhibit F — Reclamation Plan Map. <br />The recommended seeding method is by drill and seeding rates assume this <br />method. The species composition of the seed mixture recommended for <br />reclamation is shown in Table 6.4.5-2 below. <br />Table 6.4.5-2 Recommended Seed Mixture <br />Species (Variety) <br />3:1 <br />Native/ <br />Introduced <br />Cell 1 <br />Cost <br />pis/ac <br />7. <br />Replace <br />Following final <br />Stockpiles in <br />20,000 <br />Sideoats grama (Vaughn) <br />topsoil froml <br />grading <br />Cells 1, 2 <br />$7.25 <br />Switchgrass (Nebraska -28) <br />to 1.5 ft depth <br />Native <br />Warm <br />$5.00 <br />8. <br />Seed and <br />Following soil <br />NA <br />$1.90 <br />TOTAL <br />implement <br />replacement <br />$28.85 <br />weed control <br />Maximum stockpile occurring at any one time <br />Topsoil Replacement <br />Stockpiled topsoil will be placed to a minimum depth of 1.0 ft. on all affected <br />areas above the normal pool elevation of the reservoir.
