RECLAMATION PLAN <br />which has already occurred. Overcasting of rock by previous operators will not be disturbed, but <br />skyline modifications of mesa edge cuts will occur, although those effects are minor. <br />POSt-Mllllrig )l.8(1(1 USC (minor modification) <br />The post-mining land use selected for this land is wildlife habitat. However, included in that <br />use would be recreation in the form of limited camping as well as hunting. This is completely <br />consistent with the uses of surrounding lands which are basically wildlife habitat and limited <br />amounts of recreation. The environment of Table Mountain is a fairly sensitive one that does not <br />generally recover rapidly from severe disturbances. On the other hand, recovery from past <br />disturbances appears to be quite good where the soil contains a good compliment of fine materials. <br />Table Mountain has a long history of limited uses for grazing, hunting, camping, and mining. The <br />post-mining land use selected for this operation is considered consistent with both current and <br />historical uses. <br />GT8(hIIg (significant modifications) <br />Geueral Grade of Quarry Floor.• In the existing plan, grading was more simple than is the case <br />under this expanded plan. In the existing plan, the slope of the quarry floor extends from the back <br />of the mine to the outlet in one, long, fairly uniform grade. In this amended plan, the final <br />topography will be similar to the general topography of the top of Table Mountain. Near the <br />boundary between Area B and Area C the mountain top reaches a crest and then slopes <br />southeastward through Area C and southwestward to southward in Areas A and B. The existing <br />crest of the mountain will be maintained as a crest. Therefore, following a line from Area A <br />through the southeast corner of Area C, the grade will rise through Area A on a general northward <br />trend. In Area B, the grade will be somewhat more gradual but will turn and head northeast to the <br />crest of the mountain. After crossing the crest the grade will go downhill from the northern edge of <br />the mountain top to the southern edge of the mountain top. Because Area C is more or less <br />V-shaped, drainage from the northern parts of Area C will tend to naturally concentrate at the low <br />point which is at the bottom of the "V" that forms Area C. <br />Although such a configuration is easy to handle in Areas A and B, in Area C the <br />concentration of flow at the low point will require considerably more care to prevent the creation of <br />a huge pour-off in the vicinity of the bottom of the "V." This will be dealt with by creating astair- <br />step terracing using various thicknesses of soil replacement and different vegetation treatments. In <br />some places water can be diverted to existing smaller pour-offs along the south rim of the mesa, <br />thus reducing the volume that reaches the bottom of the "V." Just above the bottom of the "V" a <br />large, shallow basin will be created that can gather water and release it slowly into the major pour- <br />offs that naturally exist in this area. <br />The edges of the quarry (interface between the quarry floor and unmined adjacent land) will <br />be occupied by 3:1 slopes on east, west, and north facing quarry walls. Where the quarry walls face <br />southeast, south, and southwest, the slopes will be 4:1 to help create a more suitable exposure and <br />slope for revegetation purposes. The existing plan had very little south facing slope and therefore <br />only 3:1 was used. The amended plan contains a large amount of south facing slope, much of which <br />may be marginally visible from Highway 115. Because these slopes are often hot and dry when 3:1, <br />producing 4:1 slopes will aid in the successful revegetation. <br />Table Mountain Quarry -Castle Concrete Company Exhibit E (Amendment 1) Page 2 <br />
