coal seam while the F and Z pits mine the I seam H pit mined the G seam. The 3rd White Sandstone <br />(G coal and sandstone below) and 2nd White Sandstone (F coal and sandstone below) aze monitored at • <br />six Locations. The Lewis Shale is monitored at one location. The Johnson and Pyeatt Gulch alluvial <br />aquifers are monitored at one site in each of these drainages while the Flume Gulch alluvium is <br />monitored at two locations. The 2003 hydrologic monitoring report, Hydro-Engineering, LLC (2004), <br />presents the discussion of the monitoring results through 2003. The table on the pull-out index <br />provides basic welt data for all wells monitored in 2004. Welts GB-l, GB-2, GB-3, GF-1, GF-2 and <br />GF-3 were not required to be monitored. <br />Springs at Trapper Mine were monitored during 2004 in accordance with the approved <br />monitoring plan. Springs with measured flows of greater than 5 gpm were sampled for full suite water <br />quality parameters. Results of the 2004 spring monitoring aze presented in Table B-2 in Appendix B. <br />Table 1-1 (page 1-4) preserrts the pit and well dewatering data and volume of water used <br />for dust depression for Trapper Mine for 2004. This data shows that, on an average, approximately <br />23.0 gpm was pumped from the Trapper Mine pits during 2004. Well dewatering was started in <br />September of 2002 in the G pit. The average well pumping rate for 2004 was 25.I gpm for the G pit <br />well dewatering. This data is useful in interpreting water-level changes and consumptive use. <br />Surface-water flow and quality were monitored at only Flume Gulch (S-1), Johnson, No <br />Name, Middle Flume and East Middle Flume drainages during 2004. Flow was not observed in East <br />Pyeatt but one water quality sample was collected at this site.
