.. <br /> <br />3. What equipment is to be used in the mining operation? <br />Topsoil stripping and berm construction will be accomplished <br />by scrapers. Mining of the aggregate will be accomplished <br />by means of front end loader and trucks. <br />4. Will methods such as benching be used in the operation <br />(mine depths of up to 50' are to be mined)? <br />Other than a haul road construction to the Floor of the <br />mine, benching is not planned. <br />5. If possible (perhaps by doing some further gravel <br />excavation), slopes of the pit should be 3:1 instead <br />of 2:1 to facilitate revegetation establishment. <br />Considering the abundance of gravel on this site, we will <br />certainly change to 3:1 slopes. This will not only <br />facilitate revegetation, but make the slopes easier to work. <br />6. Are there plans to extend the excavation beyond the <br />7.6 acres presently planned? If the excavation is <br />extended after 5 years, a technical revision or <br />amendment to the permit will be necessary. <br />Expansion of the excavation and required revisions to the <br />permit are expected. <br />EXHIBIT E: <br />1. Are the berms to be a permanent reclamation feature? <br />It would seem that, if they are, there will not <br />be enough topsoil for revegetation efforts over the <br />entire 105 acres. <br />Per Pitkin County stipulations, the berms are to be <br />permanent. As stated earlier in the report, topsoil exists <br />in very large quantities on this site. <br />2. Slopes of 2:1, though pennissable, are often very <br />difficult to revegetate (holding topsoil is difficult, <br />for example). Our staff recommends that final slopes, <br />especially in the pit, be no more than 3:1. If 2:1 <br />slopes are to be left, some special methods (e.g., <br />netting) should be used to ensure successful slope <br />reclamation. <br />Noted - See Exhibit D ~~5 this report. <br />~~ CONSTRUCTION, INC <br />
