"f F <br />)Vir. Billy Owens <br />June 73, 2007 <br />Page 2 <br />the slide area in the highly rubblized zone near the slide scarp has shown total movement <br />approaching five feet to date. This represents the maximum cumulative movement detected at <br />any monitoring site since the slide occurred. This monument continues to creep downhill at a <br />very slow but steady rate. The velocities calculated from this movement aze minimal and have <br />remained steady. The corresponding accelerations are negligible. This behavior is not <br />unanticipated given the location of the monument near the slide scarp and is not indicative of <br />overall instability ofthe slide mass. Trapper will pay particular attention to the area surrounding <br />this monument and to the entire scarp area to be sure that any activities in this zone are <br />conducted safely. <br />Other monitoring points situated throughout the scarp azea have shown far less movement during <br />the eight months since the slide. Cumulative movement totals to date in order of decreasing <br />magnitude for other sites in the scarp zone are 3.0, 1.4, 0.9, 0.5, 0.5, and 0.4 feet respectively. <br />Monitoring sites on the slide block but away from the scarp area are currently stable with <br />cumulative movement typically totaling less than two tenths of a foot. Stability monitoring <br />activities will continue throughout the slide azea as appropriate and operational precautions will <br />be implemented as necessary to ensure the continued safety of all personnel working in the slide <br />azea. <br />Thank you f%Jr yCL'r prompt anerli:On r0 tnig mailer, FieSgr rtntify Cc at yCtr eazlieSL Cnnyrnienrr <br />with regazd to this request If you have questions or require further information please contact me <br />at 970-826-6122 or 970-326-5671 (cell). <br />Sincerely, <br />.~ ~.(lsr.P~-~~ <br />Karl Koehier <br />Safety Manager, Trapper Mining Inc. <br />cc'.
