~~ <br />RECLAMATION COSTS <br />• EXHIBIT L <br />This reclamation cost estimate in based on the assumption that <br />there will be no more that 20.00 acres t disturbed at any one time. <br />It also assumes, that when it comes time to recoil the SLAB rock area <br />that only 12 inches of soil would be spread over the disturbed area. <br />The remaining overburden piles would be graded and seeded. At that <br />time we will have to respread 24,200 cubic yards of topsoil. The time <br />when the most bank sloping would be necessary is either at the <br />beginning of mining when the excavated area would have slope on all <br />four aides that needed sloping. On a 25 ac. Area with would mean <br />there are 4100 linear feet (LFT) around the exterior of the hole. <br />Using the numbers shown on the typical cross section on page 17 and <br />assuming that since sloping would run concurrent with mining <br />approximately 508 of the cut/fill work would be done and 258 of the <br />rock fill would be left. The table below outlines the various areas <br />of disturbance at that time. A D-9 dozer will be used to do the <br />shaping and recoiling. The revegetation cost figure for the slab rock <br />area includes fertilizer, grass seed, mulch and drilling costs. The <br />revegetation cost for the surface rock area is only covers raking, <br />fertilizer and seed. <br /> STAGE TOTAL SOIL DEPTH <br /> N EEOS RES OILING 1 5.0^ 6~ <br /> REVEG ETATIDN SLAB AREA 1 5.00 <br /> R EVEG ETATIDN SURFACE AREA 5.0^ <br /> SLOPE CUT/FILL 2050 LINEAR FEET <br /> SLOPE ROCK FILL 1025 LINEAR FEET <br /> RES OIL @ 1 2~ 24,200 CUBIC YARDS <br /> EST/MATED UN/T COSTS FOR RECLAMAT/ON /TEMS: <br /> unit Cost <br />1.
