• <br />Red Canyon Mine - 1995 AHR <br />Page 3 <br /><10. The TSS measurements indicate that no degradation of the <br />quality of water occurred on this stretch of the Carbon Ditch. <br />The sediment pond did not discharge during the year. The pond did <br />not have any significant amount of water in it during the year. A <br />"spring" is located in the northeast corner of the pond. During <br />May the spring produced a small pond but it was not sampled for <br />field parameters. During September the spring was just a damp <br />spot. Cattails have flourished in the damp spot. <br />GROUND WATER <br />Table G-94 shows the ground water monitoring results for this water <br />year compared to the averages of previous monitoring results for <br />the same months. The alluvial piezometers (P-1 & P-2) showed water <br />levels consistent with prior years averages. <br />The Division's letter dated March 3, 1994 requested that the wells <br />completed in the E-Seam be monitored to determine at what level the <br />workings have been flooded. <br />• The 1987 Annual hydrologic report predicted the water in the mine <br />workings would reach the water level in E-1, 6355, in 1993. The <br />water level in E-1 in September 1994 was 6367.3. The water level <br />in E-1 During May and September 1995 was 6366.9 and 6366.8 <br />respectively. Based on the last two years of monitoring data, <br />there is no indication the water level in E-1 is increasing. It is <br />unlikely this monitoring well reflects the water level in the mine. <br />The elevation of the surface where the mine portals were developed <br />is approximately 6400. <br />Minrec proposes to continue monitoring the depth to water at well <br />E-1 at least one more year to confirm the water level in the well <br />is relatively stable. <br />MINE WATER <br />The underground workings were not accessible for mine inflow <br />monitoring in 1995 nor will they be accessible in the future. The <br />water level in the mine is projected to stabilize below the portal <br />according to the Raman Tempo Report, Volume 8 of 8 of the permit <br />application. For a projection of the mine filling schedule, please <br />refer to the 1987 Annual Hydrologic Report. <br />CONSUMPTIVE USE <br />None. <br />• <br />
