RECLAMATION PLAN <br /> Post-Mining Land Use <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. It should be recognized that the environment of Table Mountain is a fairly <br /> sensitive one that does not generally recover rapidly from severe disturbances. Table Mountain has <br /> a long history of limited uses for grazing, hunting, camping, and mining. The post-mining land use <br /> selected for this operation is considered consistent with both current and historical uses. <br /> Grading <br /> General Grade of Quarry Floor: The quarry floor will be graded to a gentle slope southward <br /> starting at the north edge of Stage 1 at the base of the north slope below the setback. The ultimate <br /> limit of this gentle southward slope will depend upon how far south the mining proceeds. The plan <br /> is designed such that no matter where the mining stops in its southward progress, the same outlet <br /> configuration can be created. When the southern limit of mining is reached (whether it is the south <br /> edge of Stage 1, the south edge of Stage 2, or something in between) the last approximately 300 <br /> feet of the mine will be graded with a very slight southward slope so that the entire area can drain <br /> freely into the existing drainages to the south of the Phase 1 area. <br /> Grading of Quarry Edges: The side slopes of the quarry, without any modification, would be <br /> nearly vertical walls about 25 to 30 feet high. These walls will be reduced by one of two methods. <br /> One method would involve modification of the mining to create a sloped quarry edge wall. <br /> Due to the difficulties of mining in this way, the sloping of this final wall will probably not create a <br /> suitable final grade but only leave sufficient rock so the amount of backfill required to create a <br /> suitable 3:1 slope will be reduced. This is needed because backfill material may be in short supply <br /> and it would be a waste of limited soil resources to backfill with soil that is needed elsewhere. <br /> The second method of creating a 3:1 side slope will be to simply backfill the more or less <br /> vertical wall that is mined to or very near the setback limit. This method can only be used if there <br /> is sufficient backfill material available. Backfill material must come from unused mined rock <br /> (mainly material too fine to market) and subsoils derived after stripping the most useful part of the <br /> soil component. That is, anything that is not soil or cannot be sold will be used as backfill. <br /> In all probability, the method used to create the final 3:1 side slopes of the quarry (which <br /> will only be found on the east, north, and west sides) will be a combination of these two methods. <br /> At this time it cannot be predicted how much will be created by one method and how much by the <br /> other method because it is not known how much subsoil will be acquired or how much non- <br /> marketable material will be produced in the mining process. It is not expected that there will be a <br /> deficiency in available materials, it just can't be determined how much will be available and <br /> without those values predicting the exact method of backfill and final slope production cannot be <br /> done. <br /> In conclusion, all quarry side slopes, except the gently sloping south end of the quarry <br /> floor, will be configured to between 2.5:1 and 3.5:1 with an average of very nearly 3:1. <br /> Furthermore, irrespective of how the slope is produced, the slopes will be topsoiled as a final step. <br /> Table Mountain Quarry - Castle Concrete Company Exhibit E Page E-2 <br />
