conditions above portal areas during the operational phase. <br />Retaining structures should be left in place following <br />reclamation. Therefore, even further improvements to stability <br />conditions above portal areas would be affected in the post <br />reclamation condition. <br />A minor reduction in stability conditions (on the order of 58, <br />plus or minus) will be experienced in a post reclamation <br />condition below bench level due to the surcharge effects at bench <br />level from the portal backfilling operation. Similarly, in the <br />area of the access road, where a proposed modification to permit <br />the existing radius of curvature to be approximately doubled <br />would be affected, a slight deterioration in stability conditions <br />l (on the order of 58, plus or minus) both above and below the <br />I access road is anticipated. However, the overall nature of the <br />stability condition at that location would remain essentially <br />unaltered and marginal in nature. <br />Shallow foundation systems would be recommended for both the <br />proposed crusher facility and proposed stacking tube facility. <br />An allowable bearing capacity on the order of 6000 psf with no <br />minimum dead load requirement may be used at the site of the <br />crusher facility and an allowable bearing capacity on the order <br />of 5000 psf, with no minimum dead load requirement, may be used <br />at the site of the stacking tube. The proposed crusher site is <br />located on a steep slope. Care must be taken to assure adequate <br />confinement of the soil below foundation level. If foundations <br />encroach too closely on the surface of the slope, an appropriate <br />reduction in allowable bearing capacity should be made to account <br />for the lack of confinement in that area. In the vicinity of the <br />proposed stacking tube, a groundwater level on the order of 6 <br />feet below the present ground surface was encountered. This <br />groundwater level should be taken into account during the design <br />and construction of this stacking tube facility. <br />Additional discussion and more complete recommendations may be <br />found in the body of this report. All recommendations are <br />subject to the limitations set forth herein. <br />I 2 <br />
