III. COMMENTS -COMPLIANCE Below are comments on the inspection. The comments include discussion of observations made during the inspection. 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. Brian Watterson of Twentymile Coal Company accompanied the inspection. The Foidel Creek Mine is a large active underground mine. The mining operation is in the last panel, LW panel 24 of the Northern Mining District. TCC has not begun its longwall move to the first panel of the Western Mining District (WMD). The weather started clear and cold -15 degrees F, warming to above freezing as the day continued. The mine facilities and roadways were frozen at the onset of the inspection, turning muddy as the day progressed and the roadways thawed. 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. Roadways became muddy during the day as the roads thawed, however, the roads appeared to drain appropriately. The culvert identified in the previous (10/27/2009) along the Fish Creek Bore Hole access road has been cleared. Most of the discharge from the stockpond now flows through this culvert. Some shaping of the ditch is needed to keep all of the discharge directed through the culvert. Hydrologic Balance: TCC was not pumping from TORT at the time of the inspection. TCC has buried the line from the outlet near Routt County Road No. 33 all the way to the TORT pad and pump house. A drilling crew was drilling the 4" dia. piezometer hole at the time of the inspection. Cutting fluids were contained in a mud pit on the site. No fluids were leaving the site. The east end of the ditch collecting runoff from the pad needs to be clearly defined. The piping on the west side of the new IORT pumphouse has been completed. This hole has been backfilled. 6MN reservoir is holding a small pool of runoff water and is frozen. TCC has constructed the pump house pad and has poured the concrete foundation for the pumphouse. The pumphouse still needs to be installed and the pump placed. TCC has seeded the 6MN reservoir embankment and laydown areas. Once the pumphouse installation is completed an As -built certification for the 6MN Reservoir needs to be provided to DRMS. The embankment on the 6MN sediment pond has been built up. Neither the spillway, nor the drainage channel have been constructed yet for the 6MN sediment pond. TCC has seeded the slope to the south of the 6MN sediment pond. Ponds inspected included Pond D, Pond G, 6MN reservoir, and 6MN pond. None of these ponds were discharging. Repairs to Pond D embankment and riser have been completed. TCC replaced the entire length of the discharge culvert through the embankment, including under the conveyor. TCC had compacted the repair in the embankment and has had a contracted engineering firm conduct compaction tests on the repaired embankment. TCC will need to resubmit to the Division, an as -built certification for Pond D to document the repairs were conducted in accordance with the approved design. 3 of 5 WHITE - File YELLOW - Operator PINK - Specialist
