in the A, B, F, G, K, L and Z pits, currently the L pit mines the H and/or I coal seams. The D pit <br />previously mined the Q and R seams and the I and I1 seams. H pit mined the G seam. The 3rd <br />White Sandstone (G coal and sandstone below) and 2nd White Sandstone (F coal and sandstone <br />below) are monitored at four locations. The Lewis Shale was monitored at one location but well P3 <br />was abandoned in 2016. The Johnson and Pyeatt Gulch alluvial aquifers are monitored at one site in <br />each of these drainages while the Flume Gulch alluvium is monitored at three locations. The 2015 <br />hydrologic monitoring report, Hydro -Engineering, LLC (2016), presents the discussion of the <br />monitoring results through 2015. Table 1-2 provides basic well data for all wells monitored in 2016. <br />Wells 81-03A, GE -1, GE -2, GE -3, GLUX-1 and GP -6 were not required to be monitored after the <br />first half of 2006. Monitoring of wells GLEV-1, GLEV-2 and GLEV-3 which are located on the east <br />side of the Trapper mine were started in 2015. <br />Springs at Trapper Mine were monitored during 2016 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 2016 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 2016. This data shows that water was pumped from the K <br />and L Trapper Mine pits during 2016. Well dewatering was started in September of 2002 in the G <br />pit. The average well pumping rate for 2016 was 33.1 gpm for the G pit well dewatering. This data <br />is useful in interpreting water -level changes and consumptive use. <br />Surface -water flow and quality were monitored at Flume Gulch (S-1), Johnson, No Name, <br />Ute, Middle Pyeatt, East Pyeatt, Oak, Horse, West Flume, Middle Flume, East Middle Flume, Deal <br />Gulch, East Flume and West Horse Gulch drainages during 2016.
