final pit highwall. The second pair, SM-3 and SM-4, were installed approximately mid-way along the pit. SM-3 was placed <br />approximately 110 feet south of the highwall and SM-4 was placed approximately 325 feet south of the highwall. The last <br />pair, SM-5 and SM-6 were installed in the upper third of final pit area. SM-5 was placed approximately 150 south of the <br />highwall and SM-6 was placed approximately 350 feet south of the highwall. The monuments consist of 7' to 8' sections of 2- <br />1/2" diameter drill steel driven 5-1/2' to 6-1/2' into the pi[ backfill material. <br />The monuments are [o be surveyed quarterly the first year and annually thereafter. In 2003, a level loop was <br />surveyed providing elevation information. However, due to an equipment malfunction, x and y coordinates were lost. The <br />coordinates of the initial monument survey and subsequent surveys are provided in Appendix E. <br />X. TROUT CREEK SANDSTONE <br />Monitoring of Well TCS-1 was initiated in 1995 to ensure the absence of mining impacts on the Trout Creek <br />Sandstone aquifer. Results of the monitoring efforts are provided in Appendix F. To date, no impacts from mining activity <br />are evident in Well TCS-I . TCS-1 was not sampled in May 2003 due to equipment problems. <br />49 <br />
