RECEIVED <br />U <br /> <br />• <br />Exhibit L A~~ 2 <br />Reclamation Costs Division of Minerals and GeoloBY <br />Reclamation costs have been estimated using assumptions based on the approved Mining <br />and Reclamation Plans for this Permit, recommendations contained in the Slope Stability <br />Report by Greg Lewicki P. E. (Exhibit S-Permanent Man Made Structures) and the <br />increased azea of the proposed Amendment. <br />Amendment #3 proposes to add approximately 500 feet to the shoreline length of the lake <br />that will remain following completion of gravel mining and reclamation of the site. The <br />tasks that are required to reclaim this additional disturbed area will be: <br />Rough grading of the final pit perimeter slope to 3 (h) to 1 (v), <br />Transport and placement of overburden material on the final slopes, <br />Grading of overburden material to achieve approved thickness (6-8 inches on level <br />aeeas and 6 inches on sloped areas), <br />Seed bed preparation, <br />Revegetation planting. <br />The additional slope area that the proposed Amendment #3 will add will be 500 feet of <br />slope length multiplied by the expected slope length (27 feet x 3 = 81 feet) at the new <br />lakeshore area or 40,500 squaze feet. Additional azea at the existing ground level will <br />require reclamation, as well. The extent of disturbed area at the perimeter of the pit is <br />expected to be limited to the area required for overburden soil storage berms, <br />approximately 25 feet. The total area of land expected to be disturbed near the top of the <br />final pit slopes will be 500 feet x 25 feet or 12,500 square feet. <br />Reclamation Cost Estimate <br />Task <br />Grading pit slopes (3:1) <br />Transport & place soil <br />Fine grading soil <br />Seed bed preparation <br />Reveg: Plant Seed Mix <br />-Buy Seed Mix <br />Reveg.-Apply Mulch <br />-Buy Mulch <br />Total Direc[ Cost <br />Project Management <br />Total Cost <br />Reclamation costs aze expected to be approximately $3,000 for the proposed Amendment <br />#3 area. <br />Area Equipment Production Hours Cost/hour Cost <br />1 acre Cat D7 dozer 700 cy/hr 12 $85/hr 1020 <br />1 acre Cat D7 dozer 200cy/hr 4 $85/lu 340 <br />1 acre Cat 140 H motor grader 0.75 acre/hs 2 $80Ru 160 <br />1.5 acre Cat 140 H motor grader 0.75 acre/hr 2 $80/hr 160 <br />1.5 acre Tractor & seed drill 0.5 acre/hr 3 $60/hr 180 <br /> 300 <br />1.5 acre Straw blower 2 acre/hr ] $60/hr 60 <br /> 300 <br />2520 <br />252 <br />2772 <br />
