RECLAMATION CO~ <br />This reclamation cost estimate in based on the assumption that there <br />will be no more that 6.26 acres t disturbed at any one time. it also <br />assumes, that when it comes time to resoil the area that only 12 inches <br />of soil would be spread over the disturbed area. The remaining <br />overburden piles would be graded and seeded. At that time we will have <br />to respread 9,680 cubic yards of topsoil. The time when the most bank <br />sloping work would be necessary is at the beginning of mining when the <br />west slope would have to be constructed, there are 650 linear feet (LFT) <br />along this side. The numbers used in this analysis are those shown on <br />the typical cross section shown on the Reclamation Plan Map. The table <br />below outlines the various areas of disturbance at that time. A D-9 <br />dozer will be used to do the shaping and resoilinq. The revegetation <br />cost figure used includes fertilizer, grass seed, labor and drilling <br />costs. <br />STAGE TOTAL SOIL DEPTH <br />NEEDS RES OILING fi.2fi 12~ <br />REVEG STATION SLAB AREA 5.26 <br />SLOPE DISTANCE fi50 LINEAR FEET <br />SLOPE CUT/FILL 2,275 CUBIC YARDS <br />SLOPE ROCK FILL 2,441 CUBIC YARDS <br />RES OIL @ 1 2~ 9,680 CUBIC YARD5 <br />EST/MATED UN/T COSTS FOR RECLAMAT/ON /TEMS: <br /> Unit Cost <br />1.
