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. Mr. Brian Watterson of Twentymile Coal Company accompanied the field portion of the inspection. The mine is an active underground mine. The weather was cold with snow squalls throughout the day. A fair snow pack is present throughout the mine site. Roads: Roads throughout the mine were clear of snow. Recent warm weather(above 32 degrees) has thawed the top few inches of the roads, resulting in muddy spots. These muddy spots are not causing damage to the roadway as the road bed remains frozen underneath. Access roads to Fish Creek Borehole and the south side of the RDA were plowed. Roads that are regularly used by TCC had been plowed. Roads that are used infrequently had not been plowed. Support Facilities: TCC has submitted a revision for 7 to 8 geotechnical boreholes in the area of the projected 18LT Vent borehole. (MR235). This location is near the northern extent of the permit area just to the west of Routt County Road No. 27. The proposed location was pointed out. The site is snow covered. TCC continues to remove stored metal & other unused material at the PM Bay area. Hydrologic Balance: TCC continues to pump Mine water from TORT to Foidel Creek via a 12" HDP. The discharge point at Foidel Creek is approximately where Foidel Creek flows under Routt County road No. 33. The majority of this line has been buried. TCC will continue to bury the line as weather conditions allow. TCC continues to conduct WET testing for this discharge. TCC is investigating treatment options for this location, due to previous WET test excursions. TCC reported that repairs have been conducted to the water level monitoring equipment at TORT borehole. TORT borehole#2 is not discharging or pumping to 6MN reservoir. Fish Creek Vent Shaft (FCVS) was being pumped to Pit 1. Pit 1 elevation has reached the discharge elevation at Site 7 that is flows to Pond D. Pond D was discharging approximately 0.22 on the staff gauge at the time of the inspection. The discharge water is clear with no oil sheen. Ponds throughout the mine were snow covered and frozen. The Million Gallon Tank at the PM Bay was not overflowing at the time of the inspection. Pond G was not discharging. Processing Waste: TCC is working the southern portion of RDA (area 3) and the western portion (area 4). The new Area 4 refuse material had been graded out and was tying in well to the refuse to the east of this new working area. Drainage continue to be maintained off or the RDA. No wet or ponded areas were encountered. 3 of 5 WHITE- File YELLOW -Operator PINK- Specialist
