RECLAMATION PLAN <br /> Other Variables: <br /> 1. South and west facing pit side slopes require more soil to avoid drought effects. <br /> (East facing side slopes need same soil depth as quarry floor) <br /> 2. Most southerly 300 feet of almost level quarry outlet requires less soil due to <br /> this area receiving more moisture and having less of a slope. <br /> Area of south and west facing pit side slopes: <br /> With Case 1 = 5.1 acres <br /> With Case 2 = 8.2 acres <br /> Estimated additional depth = 50% <br /> (Example: if quarry floor needs 8", these slopes will need 12" -- <br /> (8" = 2) + 8" = 12") <br /> Area of southerly 300 feet (is fairly independent of where mining stops): <br /> Area = 3.9 acres <br /> Estimated depth reduction = 30% (but not less than 4") <br /> (Example: if quarry floor needs 8", this area will need 5.6" -- <br /> 8" - (8" x 0.3) = 5.6" -- depth of 5" to 6" is OK). <br /> Based on these variables and estimated values of topsoil volumes, the depth of soil <br /> replacement under these two cases should be as follows: <br /> Case 1: <br /> Quarry Floor = 6.25 inches <br /> South and West Facing Slopes = 10.25 inches <br /> Quarry Outlet area = 4.75 inches <br /> Case 2: <br /> Quarry Floor = 7.5 inches <br /> South and West Facing Slopes = 13.5 inches <br /> Quarry Outlet area = 6.25 inches <br /> Because at the start of mining it is not known whether Stage 2 will be mined, an assumption <br /> of a worst case situation must be used. That worst case situation is that mining will cease prior to <br /> reaching the salvageable soil area in the south end of Stage 2. This is basically similar to Case 1, <br /> but with somewhat more west facing slopes that require additional soil depth (the amount of south <br /> facing side slope requiring additional soil does not change as that is located only along the north <br /> edge of Stage 1). Using this worst case situation, the soil depths that will be placed, until it is <br /> known whether the salvageable soil area on the south end of Stage 2 will be mined, will be as <br /> follows: <br /> Table Mountain Quarry - Castle Concrete Company Exhibit E Page E-5 <br />
