currently only the A pit mines the H and I coal seams. The 3rd White Sandstone (G coal • <br /> and sandstone below) and 2nd White Sandstone (F coal and sandstone below) are <br /> monitored at seven locations. The Lewis Shale is monitored at one location. The Johnson <br /> and Pyeatt Gulch alluvial aquifers are monitored at one site in each of these drainages <br /> while the Flume Gulch alluvium is monitored at two locations. The 1997 hydrologic <br /> monitoring report, Hydro-Engineering (1998), presents the discussion of the monitoring <br /> results through 1997. The table on the tan pull-out index provides basic well data for all <br /> wells monitored in 1998. <br /> Springs at Trapper Mine were monitored during 1998 in accordance with the <br /> approved monitoring plan. Springs and seeps with measured flows of greater than 5 gpm <br /> were sampled for full suite water quality parameters. Results of the 1998 spring <br /> monitoring are presented in Table B-2. • <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 1998. This data shows that, on an <br /> average, approximately 48 and 21 gpm were pumped from the Trapper Mine pits and <br /> dewatering wells, respectively. The average pit pumping rates were 12.6, 0.5, 2.4 and <br /> 32.5 gpm for the A, H, F and D pits, respectively. This data is useful in interpreting <br /> water-level changes and consumptive use. <br /> Surface-water flow and quality were monitored at the Flume (S-1), East, Far East <br /> and West Buzzard, Johnson, No Name, Ute, Grouse, Oak, Coyote, Elk and East, Middle and <br /> West Pyeatt drainages during 1998. The Johnson, No Name, East Buzzard, Coyote, West <br /> Buzzard, Ute, Middle Pyeatt, Elk, East Pyeatt, Deer, West Pyeatt, Far East Buzzard, Grouse, <br /> 1-2 <br />
