,~ <br />Reporting Period December 16, 1997 -December 23, 1997 <br />2 <br />DewaterinR Borehole Road: Slopes are snow covered and frozen. Minor water seepage continues <br />on the east side cut slope as reported previously. Survey monuments installed above the cut slope and <br />french drain continue to show a very minor northward creep. <br />Substation Slopes: Visual observations and survey data for the slope above the substation indicates <br />surface movement is continuing, although incremental movements have decreased substantially with the <br />frozen ground conditions. No advancement of the head scarp further upslope and into the Landing #2 <br />road was observed. The inclinometer installed on the Landing #2 road above the slope (I-24) vvas read <br />on 12/17/97 and shows no incremental movement. The inclinometer installed northeast of the <br />substation near the triple pole structure (I-23) was read on 12/22/97 and shows a minor incremental <br />movement at approximately 6-8 feet below ground surface. Monitoring of these inclinometers will <br />continue on at least a monthly basis. <br />Shaft Site # 1 and #2: Slopes, including the compacted soil buttress installed to stabilize the <br />shallow slope failure on the steep cut slope south of Shaft #1 are snow covered and frozen. No <br />indications of movement were detected. <br />DewaterinQ Facilities Area (New Reporting Area) <br />Inclinometers 1-13 (below the site) and 1-14 (above the site) were surveyed on 12/22/97 and 12/17/97 <br />respectively. Minor deflections at and just below ground surface level were detected th both locations. <br />Based on a review of the displacement logs, these minor deflections are attributed to movement of the <br />surface casing and to the recent change in personnel and equipment. (NOTE: MCC has purchased <br />inclinometer monitoring hardware/software and is now performing these surveys with in house <br />personnel.) No obvious shear zones are evident on the displacement logs. Monitoring of these <br />inclinometers will continue on at least a monthly basis, and future surveys will verify whether true <br />movement is occumng. <br />If you have any questions or concerns, please feel free to contact me at (970) 929-2207. <br />Sincerely, <br />mow. <br />Eric W.
