<br />Reporting Period October 08, 1997 -October 19, 1997 <br />3 <br />The completed mid-slope french drain appears to be functioning effectively. Barr Engineering's' <br />analysis of this slope indicates movement at depth may be occurring, and additional inclinometers <br />have been recommended. Inclinometers and piezometers are currently planned for the slope above <br />the previous head scarp, and for the slope to the northeast of the substation. Other locations are <br />being evaluated. Monitoring will continue. <br />Shaft Site #I and #2: The compacted soil buttress installed to stabilize the shallow slope <br />failure on the steep cut slope south of Shaft #1 was observed on 10/17. The buttress appears solid <br />and no new movement was visually detected. Slopes to either side of the buttress area were also <br />observed and appeared stable. Site lines are straight and intact. Visual monitoring and collection of <br />surface survey data will continue. <br />Electric Borehole Road: This road is complete, except for guardrail installation. Temporary <br />berms and permanent ditches are in place. Road cuts and fills are stable. <br />Shaft Site #3: The Shaft #3 site and Electric Borehole pad are 100% complete. Soil <br />slopes are dry and stable. Rock slopes and benches appear solid, but have been covered with a chain <br />link mesh for rock fall protection as a precaution. The shaft drilling contractor is fully mobilized and <br />has begun raise-boring of the shaft. <br />If you have any questions or concerns, please feel free to contact me at (970) 929-2207. <br />Sincerely, <br />~~.~~ <br />Eric W.
