RECLAMATION PLAN (changed) <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 slope will be reduced. This is needed because backfill material may be in short supply and <br />it would be a waste of limited soil resources to backfill with soil that is needed elsewhere. <br />The second method of creating side slopes will be to simply backfill the more or less vertical <br />wall that is mined to or very near the setback limit. This method can only be used if there is <br />sufficient backfill material available. Backfill material must come primarily from unused mined <br />rock (mainly material too fine to market) and subsoils derived after stripping the most useful part of <br />the 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 side slopes of the quarry will be a <br />combination of these two methods. At this time it cannot be predicted how much will be created by <br />one method and how much by the other method because it is not precisely known how much subsoil <br />will be acquired or how much non-marketable material will be produced in the mining process. Best <br />estimates show that it is not expected there will be a deficiency in available materials, it just can't <br />be determined how much will be available and without [hose values predicting the exact method of <br />backfill and final slope production cannot be done. <br />In conclusion, all quarry side slopes, except the outlet portions along the south ends of the <br />quarry floor, will be configured to between 2.5:1 to 3.5:1 on east, west, and north facing slopes <br />and with an average of 3:1. For southward facing slopes, the final slope will be 3.5:1 to 4.5:1 with <br />an average of 4:1. Furthermore, irrespective of how the slope is produced, the slopes will be <br />topsoiled as a final step. <br />bzclusioa of Old Quarry Edges: In the small existing quarry there are cliffs along the east side that <br />are nearly vertical and range from a few feet high to as much as 25 to 30 feet high. Because these <br />cliffs are close to the mesa edge which cannot be further disturbed, remining these cliffs to create a <br />more gradual grade prior to backfilling is not generally possible without doing damage to the mesa <br />edge. In most areas these cliffs will need to be backfilled to create a final slope. Fortunately, the <br />lineal feet of wall in this condition is small, but the need to do this will somewhat reduce the <br />available backfill for quarry edge walls created elsewhere. (NOTE: This wording is derived from <br />the original permitted plan. Most of this work has already been completed.) <br />WatOt ReSOlli CCS (significant modifications) <br />There are no permanent streams within the area that will be mined. Drainage is generally to <br />the south. Water flow from the mining areas only occurs during melting of heavy snows or after <br />thunderstorms. In the grading of the quarry floor, the drainage topography within the quarry will be <br />established so as to connect flows from within the quarry to the historical drainageways. Retention <br />of water within the quarry may occur in very shallow basins, but the grading of the quarry floor <br />should eliminate most of those so that little if any water remains within the quarry for any <br />significant period of time. <br />A small spring southeast of Area A and below the mesa crest has been investigated and <br />found to produce far less water than the 25 gpm that was indicated in the previous operator's permit <br />application. This quarry operation is not expected to influence the rate of flow of this spring or the <br />Table Mountain Quarry -Castle Concrete Company Exhibit E (Amendment 1) Page 3 <br />
