The following recommendations for monitoring of slope stability should be followed: <br />1. A visual inspection of the excavated slopes should be done on a weekly basis for <br />the duration of mining. This inspection should consist of walking the existing <br />ground and looking for any signs of stress cracks or other potential signs of slope <br />failure. Some minor sloughing of slopes is expected on any mine site. The intent <br />of this inspection is to locate potential major slope failures that could potentially <br />extend back into a structure. <br />2. A visual inspection should be done after a major precipitation event that has <br />saturated the ground using the same procedures. A major precipitation event <br />would be defined as a storm that produces an intensity level reached once in 50 <br />years on the average. <br />3. If a visual inspection detects signs of a potential slope failure, qualified personnel <br />should be contacted to evaluate and recommend remediation work to stabilize <br />the area. <br />4. If no visible signs of slope failure are detected during mining, then the inspection <br />period could be reduced to once per 6 months after mining completion, or after <br />every major precipitation event. <br />J&T Consulting, Inc. <br />Loloff Construction, Inc. - Loloff Pit <br />Slope Stability Analysis <br />Page 6 <br />
