<br />Reporting Period December 02, 1997 -December 09, 1997. <br />areas of concern is being performed as needed. Individual areas are discussed th detail in the following <br />sections. Supporting documentation is attached for your review. <br />Lower Svlvester Gulch Road: Slopes are generally snow covered and frozen, making it difficult to <br />inspect ground conditions. However, no "breaks" th the snow cover were observed which would <br />indicate new sloughing. Minor ground water seepage continues in a number of locations. Visual <br />monitoring of this slope will continue. <br />Installation of replacement inclinometers I-2 and 1-4B are unlikely to occur this month, due to frequent <br />snow storms, the lack of availability of track mounted drilling equipment, and the upcoming holidays. <br />January installation appears feasible. Observations of these slopes will continue. <br />Upper Svlvester Gulch Road: The surficial slide on the steepened cut slope at approximately <br />Station 76+00 reported last week continues to waste a small amount of earth into tho roadside ditch. <br />The slope is snow covered and frozen with no discernable cracking, and appears to have stabilized for <br />the time being. MCC will continue to monitor this slope and will take appropriate actions to maintain <br />the ditch and road should additional sloughage occur. <br />Main Embankment (F-Wall): Replacement inclinometers for I-9 and I-10 are now planned for <br />January. <br />Dewatering Borehole Road: Slopes aze 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 northwazd creep. Monitoring will continue. <br />Substation Slone: 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 inclinometer placed th the Landing #2 road (I-24) shows no <br />movement. The inclinometer (I-23) to the northeast of the substation is beginning to show a potential <br />slip plan at approximately 8 feet BGS. Incremental movement and velocity are small. MCC will <br />continue to monitor this slope. <br />Shaft Site # l and #2: Slopes, including the compacted soil buttress installed to stabilize the <br />shallow slope failure on the steep cut slope south of Shaft #l aze snow covered and frozen. No <br />indications of movement were detected. Visual monitoring will continue. <br />Dewaterine Facilities Area (New ReoortinQ Area) <br />Inclinometers I-l3 (below the site) and I-l4 (above the site) were surveyed on December 4th. No <br />movement was detected, except within the topmost four feet of casing. In both cases, this movement is <br />within the "stickup" portion of the casing and is attributable to surface traffic from reclamation efforts <br />in the viciniri. <br />
