~. - J . <br />.• ' <br />Mr. Don A. Rapp - 2 - April 10, 1985 <br />2. The sequence of the proposed mining operation is not clear from the mining <br />k plan and accompanying map. The various areas to be mined, and the order in <br />/ \ which they are to be mined should be indicated in some way. <br />3. What is the location of the work area discussed as the location for <br />crushing of material? Is this the stockpile area shown near the western <br />boundary of the permit area? If so, what are the "work areas" shown in the <br />northeastern part of the permit area? <br />4. To what depth is rock to be removed in each of the various areas to be <br />mined? If depth of removal is not an appropriate measure, some indication of <br />x the plans for extent of removal from rock outcrops should be given. Cross <br />sections could be useful in this regard. <br />5. Are old rock stockpiles from previous mining operations to be removed as a <br />part of this operation? If so, the relationship of this removal to the rest <br />of the mining operation should be described. Are all such old rock piles now <br />shown on the map? <br />6. More detail on the exact method of mining should be given. Is the removal <br />of rock in any given area to be done using benches, or segments of an outcrop <br />of some proportions, or some other method? The typical quarrying method is by <br />the use of benches. This is also appropriate because benches are usuallly <br />more easily reclaimed than sheer rock faces. Please clarify this matter. <br />~. What is the estimated life of this mining operatbn? <br />8. I note that a road easement to this quarry is a part of the legal <br />right-to-enter this proposed permit area. Is the existing road adequate for <br />this mining operation, and is the existing road even to be used? If a new <br />road is constructed or an existing road is extensively upgraded as a part of <br />the mining operaion, it should be included as a part of the permit area. If <br />the road is included, the maps, acreage and legal description would also need <br />to be changed. Other landowners might have to be notified, as well. <br />9. Given the complexity of the topography in this area, it may be necessary <br />to use a topographic map to illustrate the various features of this operation <br />and their relationships to one another. If you cannot adequately clarify some <br />of the items mentioned above, such a topographic map might be useful. In any <br />case, the map, in combination with the mining plan, should clarify these <br />various questions. <br />Exhibit D <br />1. The evaluation of this site by the Colorado Division of Wildlife should be <br />~~,`p . submitted to us as soon as it is available. It is difficult to fully evaluate <br />your reclamaton plan without this input. This evaluation letter should be <br />submitted before the Board considers this application. <br />2. The evaluation of soils and vegetation given by the Soil Conservation <br />Service seems to be for only those areas of old disturbance. However your <br />plan mentions the probable disturbance of areas within the permit area that <br />have not been previously disturbed. No data on vegetation and soils for such <br />areas seems to have been provided. This points up the need for data on <br />vegetation and soils for the entire permit area. In this way, the potential <br />
