As Section 3.3.3 of Trapper's permit details the initial configuration of the monitoring system; <br />this report updates the configuration of the monitoring system. Since the last report in March, <br />Station 1 has been removed due to the advance of mining operations. The GPS originally <br />located with Station 1 has been relocated to Station 2. Station 5 has been established with a <br />borehole and installed sensors, but does not have a GPS station at this time. <br />Inclinometer graphs for the period October 15, 2009 (with the exception of Station 5 which <br />begins July 14, 2010) through September 29, 2010 are attached. Movement is measured in <br />inches of displacement (a change from the previous "Degrees Tilt" measurement) and represents <br />rotation of inclinometer casing. Beginning values can be seen at the October 150' point on the <br />graphs. There has been no significant movement in the inclinometers during the monitoring <br />period. <br />Piezometer reading graphs for each site are also attached, and represent the same period as the <br />inclinometers above. <br />Stations 2, 3, and 4 currently have GPS monitoring stations. Displacement histories for these <br />sites for the period of July 24, 2010 through September 22, 2010 are attached. <br />Please contact me if you have any questions. <br />Sincerely, <br />Seth A. Puls, PE <br />Engineering Coordinator <br />c FVL <br />P.O. Box 187 Craig, Colorado 81626 (970) 824-4401
