Minor Revision No. 218 -Update Page 2 <br />November 7, 1997 <br />Area 4: Seven (7) holes to the east of the MSB in Area =1 were completed. One of <br />the holes was completed as an inclinometer and the remainder of the holes were <br />abandoned as approved . Drill roads were constructed from the light-use road <br />located south of the MSB. Reclamation of the drill roads has not yet been <br />completed, but is planned to be completed within the next two weeks. <br />Area 5: Seven (7) holes in Area 5 were completed. All holes were abandoned <br />except for two, which were completed as piezometers. A stream crossing was placed <br />in Sylvester Gulch to access the holes in this area and has since been reclaimed. All <br />road reclamation for this area is complete. <br />Area 6: Seventeen (17) holes in Area 6 were completed. Six (6) holes were <br />completed as piezometers and the rest were abandoned as approved. The road <br />reclamation has not been completed and will not likely be completed until spring. <br />MCC will utilize the main drill road constructed through this area to monitor the <br />piezometers. In addition, IvfCC has laid a temporary power cable along the road to <br />provide power to the Sylvester Gulch fan until the new Sylvester Gulch substation is <br />brought on-line, which is expected to be in mid- to late November. As December is <br />an inappropriate time to begin reclamation, it will be postponed until spring. <br />. Area 7: Fifteen (15) holes in Area 7 were completed. Five (5) of the holes were <br />completed as piezometers and the rest were abandoned as approved. All reclamation <br />of any new disturbance has been completed. The existing light-use road remains to <br />provide continued access to monitoring well RAV-4B and the new piezometers. <br />Area 8: Nine (9) holes in Area 8 were completed. Four (4) of the holes were <br />completed as piezometers and the rest were abandoned as approved. All of the <br />reclamation in this area has been completed. <br />Area 9: The holes in Area 9 have been eliminated from the geotechnical <br />investigation and will not be drilled. <br />Area 10: Nine (9) holes in Area 10 were completed. Three (3) of the holes were <br />completed as piezometers and the rest were abandoned as approved. Most of the <br />reclamation has been completed in this area; however, the drill road and stream <br />crossings will remain until spring. The road will be used to access unfinished <br />construction azeas at the outlet of CSLY-4, which is planned be completed by the end <br />of November, inclinometer I-9 and piezometers. As December is an inappropriate <br />time to begin reclamation, reclamation of this road will be postponed until spring. <br />The two stream-crossings culverts, which will remain aze each 24-inches in diameter <br />and of adequate size to pass the spring run-off in Sylvester Gulch. The stream <br />crossings will be reclaimed at the time the road is reclaimed. <br />
