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 /> IHC Scott, Inc.—Bernhardt Sand and Gravel Pit <br /> nal <br /> J&T Consulting, Inc.
