• mining occurred during July or August 1995. The collar <br />elevation of DH 66 was originally established in' 1982 at <br />8209.89 feet. The monitoring point established at this site was <br />surveyed in January 1994 at elevation 8189.50 (-20.39 feet). An <br />apparent error in survey elevation data exists for this site. The <br />October 1994 survey indicates a minor (0.07 foot) gain in <br />elevation compared to the January 1994 survey. The 1996 <br />average survey performed by UTE Engineering showed an <br />increase in elevation of 0.66 feet. <br />Station DH 68: Drill hole 68 is located over Panel Z with approximately 1250 <br />feet of cover. Advance mining occurred directly under DH 68 in <br />October 1993. The collar elevation of DH 68 .vas originally <br />established in 1982 at 8191.92 feet. The monitoring point <br />established at this site was surveyed in January 1994 at elevation <br />8191.53 (-0.39 feet). The October 1994 survey indicates a <br />minor (0.02 foot) loss in elevation compared to the January 1994 <br />survey. The 1996 average survey performed by UTE <br />• Engineering showed an increase in elevation of 0.55 feet. <br />Station 94: Station 94 was newly established in 1993 and is located at the <br />Grosse-Rhode cabin identified as structure 32 on permit No. C- <br />81-038; Map No. 9-7. Advance mining of Panel Y in the <br />vicinity occurred during December 1993 and retreat mining <br />occurred in early 1994. This station overlies approximately <br />2000 feet of overburden. The monitoring point established at <br />this site was surveyed December 8, 1993 at elevation 8755.95. <br />The October 1994 survey indicates an elevation loss of 0.17 feet <br />compared to the December 8, 1993 survey. The June 1995 <br />survey performed by UTE Engineering showed an increase in <br />elevation of 1.54 feet. During past subsidence monitoring, Ute <br />Engineering found a discrepancy in this point. As a result, a new <br />subsidence point was established. See the report from UTE <br />Engineering behind tab 7 for an explanation of this data. <br />Station 95: Station 95 is located at the North quarter-corner of Section 15. <br />The elevation of Station 95 was defined by satellite survey in <br /> <br />Pale -6- <br />
