Comments also describe any enforcement actions taken during the inspection and the facts or evidence supporting the enforcement action. This was a partial inspection conducted by Janet Binns of Colorado Division of Reclamation, Mining and Safety. Scott Cowman, Will Dennis, and Brian Watterson of Twentymile Coal Company accompanied the field portions of the inspection. The Foidel Creek Mine is a large active underground mine. The mine has completed its longwall move to the last panel of the Northern:Mining District (NMD). The weather started clear and warm, clouding up in the afternoon. A thunderstorm with hard rain and hail moved in about 2:20 pm and lasted 20 minutes to a half hour. The mine has been receiving frequent afternoon storms throughout the month of June. The mine site was damp prior to the inspection and the ground is muddy. Roads: Haul Roads and access roads throughout the mine are in relatively good condition. TCC has cleaned and shaped many of the ditches throughout the facilities area. Ditches around facilities area are functional and no ditch or drainage failures of the structures were observed around the facilities area. The RDA 100-year ditch on the north side of the pile has yet to be cleaned. Drainage still runs out of the rip-rapped channel and down the east slope, but all drainage from the refuse pile still is directed to Pond D. 6MN access road remains in fair condition. The road had muddy spots but no pooled water and was still easily travelled. Fish Creek Borehole Access road is also in good condition and runoff is directed off the access road. Hydrologic Balance: TCC was not pumping from 1 ORT at the time of the inspection. According to mine personnel, this location has not been turned back on since pumping ceased in May. 6MN reservoir is holding runoff water. As-built certification for 6MN Reservoir has not been provided to DRMS yet. This certification needs to be provided to DRMS and on file at the mine. Piping has been connected to the 6MN million gallon tank but the pumping station has not been constructed at the 6MN reservoir. An excavation has been stated along the 6MN Upland Diversion ditch for burial of the 6mn transfer line current line. This excavation location was abandoned and the line connected adjacent to this hole. This excavation needs to be filled back in. Stabilization seeding is needed on the outslopes of the 6MN reservoir. The embankment is currently bare, allowing for establishment of weedy species on the outslopes. The mine area has received close to 2 inches of precipitation since the beginning of the month. Ponds inspected included Pond F, Pond G, Pond E, and 6MN pond. None of these ponds were discharging. Pond D was discharging, and water was flowing from Pit 1 to Pond D. Pond B was discharging clear, measuring 0.04 on the staff gauge. The oil booms need to be replaced but no oil sheen was discernable on the water surface. The summer field staff was collecting water samples at Pond B at the time of the inspection. 3 of 5 WHITE- File YELLOW-Operator PINK-;Specialist
