' previous reports the slide that occurred on the northeast wall has shown no signs <br />of continued movement since the steepness of the wall slope was modified in <br />1999. Based on data collected from boreholes in the 2003 geotechnical <br />investigation, a number of relatively shallow foliation surfaces will be <br />encountered below the current main pit elevation of 6,340 feet, and the north <br />' walls should be monitored closely as the final 140 feet of excavation occurs. <br />' The remaining walls are also currently stable, though the present analysis for the <br />west wall and the southeast wall each indicate the possibility for wedge failures. <br />' These two walls of the quarry should continue to be monitored as the mining <br />continues. As documented in the past, localized raveling, especially along the <br />' south walls is likely to continue. Continuation of the safety-minded policies <br />already in place, which limit the height of the exposed highwall, as well as the <br />' reclamation of exposed highwalls as soon as possible following blasting and rock <br />haulage, will aid in minimizing the potential for sliding. <br />3- <br />
