aquifer and have been mined in the A, B, G and Z pits, currently the A and G pits mine the <br />H coal seam while the Z pit mines the I seam. H pit mined the G seam. The 3rd White <br />Sandstone (G coal and sandstone below) and 2nd White Sandstone (F coal and sandstone <br />below} are monitored at seven locations. The Lewis Shale is monitored at one location. <br />The Johnson and Pyeatt Gulch alluvial aquifers are monitored at one site in each of these <br />drainages while the Flume Gulch alluvium is monitored at two locations. The 2001 <br />hydrologic monitoring report, Hydro-Engineering, LLC (2002), presents the discussion of <br />the monitoring results through 2001. The table on the pull-out index provides basic well <br />data for all wells monitored in 2002. <br />Springs at Trapper Mine were monitored during 2002 in accordance with the <br />approved monitoring plan. Springs with measured flows of greater than 5 gpm were <br />sampled for full suite water quality parameters. Results of the 2002 spring monitoring are <br />presented in Table B-2 in Appendix B. <br />Table 1-1 (page 1-4) presents the pit and well dewatering data and volume of <br />water used for dust depression for Trapper Mine for 2002. This data shows that, on an <br />average, approximately 12 gpm was pumped from the Trapper Mine pits during 2002. <br />Well dewatering was started in September of 2002. The average pit pumping rates were <br />7.9 and 2.5 gpm for the A and F pits, respectively, and 2.1 gpm from the G pit well <br />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), <br />Johnson, No Name, East Pyeatt, Middle Flume and East Middle Flume drainages during <br />2002.
