<br />Reporting Period September 30, 1997 -October 7, 1997 <br />3 <br />Dewaterinr? Borehole Road: The sight lines and slope conditions remain as previously reported. <br />Survey monuments were placed above the top of the redesigned cut slope on September 24, as <br />committed to in our MR 224 response. Subsequent surveys on September 27 and October 4 show <br />some minor movement that MCC believes is attributable to survey error. Monitoring will continue. <br />Clearing work for the french drains for this slope is in progress. <br />Substation Sloae: Visual observations and survey data for the slope above the substation indicates <br />movement is continuing at a slow and gradual pace, with incremental movements decreasing over time. <br />No advancement of the head scarp further upslope and into the Landing #2 road vas observed. The <br />completed mid-slope french drain appears to be functioning effectively. Monitoring will continue. <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 October 7. The buttress appears solid and no <br />new movement was visually detected. Slopes to either side of the buttress area were also observed and <br />appeared stable. Site lines aze straight and intact. Visual monitoring and collection of surface survey <br />data will continue. <br />Electric Borehole Road: This road is complete, except for guardrail installation. Temporary berms <br />and permanent ditches are in place. Road cuts and fills are stable. <br />Shaft Site #3: As of October 7, the Shaft #3 site is 98% complete with final finish work for rip rap <br />placement in progress. Soil slopes are dry and stable. Rock slopes appear solid. The shaft drilling <br />contractor has mobilized to the site. <br />If you have any questions or concerns, please feel free to contact me at (970) 929-2207. <br />Sincerely, <br />~. w <br />Eric W.
