' 4 <br />Reporting Period November 19, 1997 -December 1, 1997 Page 3 <br />Substation Slope: Visual observations and survey data for the slope above the substation indicates <br />surface movement is continuing. No advancement of the head scarp further upslope and into the <br />Landing #2 Road was observed. The completed mid-slope french drain appears to be functioning <br />effectively. An attempt to read the mid-slope inclinometer (Inclinometer 1-26) was unsuccessful as the <br />probe would not pass the shear zone at 20 feet below ground surface (BGS). Additional comparative <br />surveys of the inclinometer placed in the Landing #2 Road (I-24) show no movement. An additional <br />inclinometer (1-23) to the northeast of the substation shows a small movement between 0 and ]0 feet <br />BGS. 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 remains solid and no new movement was visually detected. <br />Slopes to the east side of the buttress area, and the surficial slide area reported previously also appear <br />stable. Visual monitoring and collection of 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 />~~ LV , i~~ <br />Eric W.
