below the HI aquifer. The H and I coal seams and sandstone between these two coals have been <br /> termed the HI aquifer and have been mined in the past in the A, B, F, G, K, L and Z pits, currently <br /> the L pit mines the H and I coal seams. The D pit previously mined the Q and R seams and the I and <br /> I1 seams. H pit mined the G seam. The 3rd White Sandstone(G coal and sandstone below) and 2nd <br /> White Sandstone (F coal and sandstone below) are monitored at four locations. The Lewis Shale <br /> was monitored at one location but well P3 was abandoned in 2016. The Deacon,Johnson and Pyeatt <br /> Gulch alluvial aquifers are monitored at one site in each of these drainages while the Flume Gulch <br /> alluvium is monitored at two locations. The 2018 hydrologic monitoring report, Hydro-Engineering, <br /> LLC (2019), presents the discussion of the monitoring results through 2018. Table 1-2 provides <br /> basic well data for all wells monitored in 2019. Wells 81-03A, GE-1, GE-2, GE-3, GLUX-1 and <br /> GP-6 were not required to be monitored after the first half of 2006. Monitoring of wells GLEV-1, <br /> GLEV-2 and GLEV-3 which are located on the east side of the Trapper mine were started in 2015. <br /> Springs at Trapper Mine were monitored during 2019 in accordance with the approved <br /> monitoring plan. Springs with measured flows of greater than 5 gpm were sampled for full suite <br /> water quality parameters. Results of the 2019 spring monitoring are presented in Table B-2 in <br /> Appendix B. <br /> Table 1-1 (page 1-5) presents the pit and well dewatering data and volume of water used <br /> for dust suppression for Trapper Mine for 2019. This data shows that water was pumped from the L <br /> Trapper Mine pit during 2019. Well dewatering was started in September of 2002 in the G pit. The <br /> average well pumping rate for 2019 was 21.5 gpm for the G pit well dewatering. This data is useful <br /> in interpreting water-level changes and consumptive use. <br /> Surface-water flow and quality were monitored at Flume Gulch (S-1), Johnson, No <br /> Name, Ute, Middle Pyeatt, East Pyeatt, Oak, Horse, West Flume, Middle Flume, East Middle <br /> Trapper Mining Company 1-2 <br /> 2019 Annual Report <br />
