Large scale <br /> dewatering combined with the topsoiling activities needed throughout the site will dictate the bond <br /> for the Ready Mix Pit. Below is a description of the reclamation activities, followed by a <br /> calculation of the estimate bond. <br /> 1. Dewatering 7.3 acre pond. 187 ac-ft @ $75/ac-ft= $14,025 <br /> 2. Replace topsoil on all disturbed areas. Six inches over 19.4 acres. 15.649 CY @$1.50 CY <br /> to haul and place=$23,474 <br /> 3. Remove all facilities and equipment. $10,000 <br /> 4. Seeding and mulching all applicable areas. 19.4 acres @ $700/acre=$13,580 <br /> Worst case reclamation costs for this scenario are shown in Table L-1 below: <br /> Table L-1 Reclamation Task and Cost Estimate <br /> Activity Description Time(Months) Cost($) <br /> Dewatering Phase 1 lake _ 0.25 14,025 <br /> Replace topsoil on all disturbed areas 1 23,747 <br /> Remove all facilities and equipment 0.25 10,000 <br /> Seed and mulch all topsoiled areas 0.25 13,580 <br /> Totals 2.5 $61,352 <br /> DRMS Costs (28% x direct costs) $17,179 <br /> Total Bond Amount $78,531 <br /> Ready Mix Pit October 2017 L-1 <br />
