6.4.5 Exhibit E -Reclamation Plan <br />• <br />• <br />6.4.5.6 TOPSOIL REPLACEMENT <br />Topsoil will be segregated during stripping. Topsoil salvaged from the existing <br />ground surface of the mining excavation will be placed in designated areas <br />replacement during reclamation. Topsoil replacement will occur on the top and <br />exterior slopes of the berm surrounding the pond excavation. Replacement will <br />begin at the northeast corner of the west pit mining operation and continue in a <br />clockwise fashion around the pit. Topsoil will be replaced to a depth of 0.25-0.50 <br />feet. Topsoil quantities for both the east and west pits are provided in Table 3 - <br />Topsoil Replacement Volume Summary below. <br />Table 3 -Topsoil Replacement Volume Summary <br />Average Topsoil Depth 0.50 ft =0.17 yd <br />Area ft2 Volume [yds31 <br />West Pit 2,326,718 43,087 <br />East Pit 439,127 8,132 <br />TOTAL 2,765,845 51,219 <br />6.4.5.7 SEEDING AND FERTILIZING <br />Currently, agricultural crops including alfalfa, wheat, hay and trees are the <br />dominant vegetation. <br />The proposed seeding areas are shown in Exhibit F -Reclamation Plan.
