CRYSTAL PIT <br />EXHIBIT D <br />• RECLAMATION PLAN <br />FINAL LAND USE SELECTED: The final land use selected for this site <br />is as wildlife habitat. This is consistent with the existing and <br />surrounding uses and it is not anticipated this use would present any <br />conflict for adjacent land uses when the operation is finally <br />terminated. <br />OVERBURDEN REPLACEMENT: The; material to be mined in this operation <br />is essentially the overburden. Therefore, as the material is removed <br />the final topographic configuration, not including the fine grading, <br />is achieved. No overburden replacement will actually occur, other <br />than the redistribution of soil which is covered under a separate <br />section of this exhibit. <br />SLOPE GRADIENTS OF THE RECLAIMED LAND: In many operations <br />• considerable depths of material are removed as a result of the mining. <br />On this operation the depth of mining is to be limited to a maximum of <br />about 5 to 6 feet. With such a thin veneer of material removed there <br />is little opportunity for drastic changes in the topography to occur. <br />Except for a slight change in the elevation and a slight steepening of <br />the slopes, the final topography will be very much like it is in the <br />pre-mining condition. <br />Figures 1 and 2 Csee the mining plan) show typical cross-sections <br />across the valleys to show the change from the present to the final <br />topographic configuration. As can be seen, the slopes become slightly <br />steeper because a lens shaped section is removed from the sides of the <br />valley, but this increase in steepness will be very slight. For <br />example, a 50 foot long slope with an elevation change of 20 feet has <br />a slope gradient of 2.5:1. If 5 feet is removed from the bottom and <br />the depth is gradually decreased to zero at the top, the slope then <br />becomes 2: 1. Such an increase is of little concern. <br />• <br />15 <br />
