l^ w <br />Reporting Period November 4, 1997 -November ] 0, 1997. <br />Landing #2 Road: The light-use road to Landing #2 was inspected on November 7. Soil cut and <br />fill slopes remain stable throughout the length of the road, and hydroseeding of these slopes has been <br />completed. Drainage ditches and berms are in place and functional. <br />Dewatering Borehole Road: Minor water seepage continues on the east side cut slope as reported <br />previously. Survey monuments installed above the cut slope and french drain continue to show a very <br />minor northward creep. Monitoring will continue. <br />Substation Slooe: Visual observations and survey data for the slope above the substation indicates <br />surface movement is continuing at a slow and gradual pace, with incremental movements decreasing <br />over time. No advancement of the head scarp further upslope and into the Landing #2 Road was <br />observed. The completed mid-slope french drain appears to be functioning effectively. The first <br />comparative survey of the midslope inclinometer/piezometer set described last week (Inclinometer 1-26) <br />indicates the slip plane for this slope is at approximately 20 feet below ground surface, and the <br />groundwater level is 36 feet below ground surface. Since bedrock depth is at 50 feet, this provides <br />some confirmation for our previous assumptions that the failure on this slope is relatively shallow. <br />MCC will continue to monitor this slope. <br />Shaft Site # 1 and #2: The compacted soil buttress installed to stabilize the shallow slope failure on <br />the steep cut slope south of Shaft #1 was observed on November 7 and November l0. The buttress <br />appears solid and no new movement was visually detected. Slopes to the east side of the buttress area, <br />and the surficial slide area reported previously also appear stable. Visual monitoring and collection of <br />surface survey data will continue. <br />If you have any questions or concerns, please feel free to contact me at (970) 929-2207. <br />Sincerely, <br />~ w 7~.~ <br />Eric W.
