S. Estimate of reclamation costs (6.3.4.(2): <br /> a. Point of maximum disturbance:This point is estimated to be approximately 2 years after <br /> initiation of site operations. The disturbance at this point (all dimensions in feet)will <br /> include fencing, access road (25 by 550), loading/storage area (100 x 200),work area <br /> (plant site) (200 x 200), soil stockpiles (2 each 400 x 8 along access road, 1 each 450 x 20 <br /> on west side), (2.0 acres without soil and 0.3 acres with undisturbed soil) and actual <br /> excavation area of approximately 3 acres: 1.5 acres mined the first year(to produce <br /> about 47,000 tons)and 1.5 acres stripped for the next year's mining.Therefore, <br /> maximum total acres is 5.3 acres of which 5.0 needs soil and 0.3 does not need soil but <br /> will need to be ripped. (Note: this assumes a 7-year life as described in mining plan, <br /> Exhibit C. Peak cost would be less with a 10-year life.) <br /> b. Unit and total costs: <br /> Action (incl.
