Table 2 shows a breakdown of this worst case scenario. The costs quoted are based on GLA <br /> experience and DBMS values from recent evaluations of this site. <br /> Table 2—Worst Case Reclamation Scenario Costs <br /> Reclamation Task Comments Reclamation Cost <br /> Structure demolition Scales,scale house,&fuel farm $1,783 <br /> Dewatering of Ponds 16 and 2(880 Cost of roughly$60/ac-ft $52,800 <br /> ac-ft) <br /> Backfilling of 1000 of highwall Accepting DRMS calculation i $16,475 <br /> Topsoiling(6"deep)of 1000'of Cost of roughly$0.59/CY $655 <br /> highwall along its top 60'(1111 CY) <br /> Topsoiling(6"deep)of production Cost of roughly$0.59/CY $9,851 <br /> area(16,698 CY) <br /> Seeding and mulching all areas Cost of$2000/acre $44,000 <br /> needing revegetation(22 acres) <br /> Mobilization of crew and $10,723 <br /> equipment ! <br /> Subtotal ii Before indirect costs i $136,287 <br /> DRMS Indirect Cost(25%) i _ 39,523 <br /> Total - -- <br /> __.. --- -- -- $175 810 <br /> All mining activity,regardless of phase, is limited to 1000 feet of unbackfilled highwall. Therefore, <br /> the maximum possible backfilling needed is that required to take a vertical slope to 31-1:1 V for a <br /> height of 25 feet, and along a distance of 1000 feet. The topsoiling requirements of the site in the <br /> worst case reclamation area a combination of the topsoil needed along the 1000 backfilled feet, and <br /> the topsoil needed on the production area located in Phase 3A. <br /> The bond for the operation should be$175,810. <br /> Please feel free to contact me with any questions. <br /> Sincerely, <br /> Ben Langenfeld, P.E. <br /> Greg Lewicki and Associates <br />
