RECLAMATION COST ESTIMATE <br /> The following Reclamation cost estimate in based on the <br /> assumption that there will be no more that 9.99 acres t disturbed <br /> at any one time. The time when it would be most expensive to <br /> reclaim the site is just before mining ends and the site is <br /> totally striped and a short working face exists across the site. <br /> It also assumesg) that when it comes time to resoil the area, an <br /> average of 10 inch of soil would be spread over the disturbed <br /> area. At that time we will have to respread 11, 940 cubic yards <br /> of topsoil. Approximately 700 feet of working face sloping would <br /> be necessary and the exterior slopes will be done as mining <br /> progresses. The table below outlines the various areas of dis- <br /> turbance at the time explained above. The areas needing work in <br /> this analysis are shown on the Reclamation Bond Map following this <br /> worksheet. A D-9 dozer will be used to do the shaping and <br /> resoiling. The revegetation cost figure used includes fertil- <br /> izer, grass seed, labor and drilling costs . <br /> STAGE TOTAL SOIL DEPTH <br /> NEEDING RESOILING 8.88 AC 10, <br /> REVEGETATION AREA B.SB AC <br /> WORKING FACE LENGTH 70O FT <br /> RESOIL Q 1 O' 1 1 ,940 CUBIC YARDS <br /> WORKING FACE FILL 5.80 CY/LFT <br /> EST/MATED UNIT COSTS FOR RECLAMATION ITEMS: <br /> unit Cost <br /> 1.
