I capability. The effect of the recommended stabilization <br />procedures and construction of the proposed retaining structures <br />I will actually result in a small increase in stability conditions <br />I above the portal areas during the operational phase. It is our <br />intention to leave these retaining structures in place following <br />I reclamation. Therefore, even further improvements to stability <br />conditions above the portal areas would be affected by the post <br />I reclamation condition. <br />I In the areas below the bench level, the proposed <br />modifications will have minimal effect on existing stability <br />J conditions for the operational phase. A minor reduction in <br />stability conditions (on the order of 58, plus or minus) will be <br />l experienced in the post reclamation condition due to the <br />surcharge effects at bench level from the portal backfilling <br />1 operation. <br />I ~§ ~- <br />Existing conditions along the easternmost end of the <br />I existing access road were again found to exhibit marginal <br />stability. The effects of the proposed modification in that area <br />I to permit the existing radius of curvature to be approximately <br />I doubled were again to cause a slight deterioration in stability <br />conditions (on the order of 58, plus or minus) both above and <br />below the access road. The overall nature of the stability <br />condition at that location would remain essentially unaltered and <br />marginal in nature. We would anticipate some level of routine <br />' maintenance to be required along the entire access road due to <br />the potential for intermittent instability. One area in <br />' particular which will be subject to high levels of maintenance <br />13 <br />
