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 inspection. The mine is an active underground mine. The weather was cool, windy and cloudy. Roads: Roads throughout the mine were dry and well graded. 6MN access road remains in good condition. No additional work at the Fish Creek crossing has been necessary. The water level in Fish creek has dropped well over a foot since the May inspection, and was well within the main Fish Creek channel. No additional road base material has been removed from the Fish Creek floodplain. TCC will need to submit a revision to the permit documenting the additions to the roadway. Hydraulic oil spill on the 6MN pad near the pump house continues to be cleaned up. The area around the 6MN pump house has been graded, but hydraulic oil continues to leak from the pump house. TCC continues to maintain an absorbent boom and napkins in the inlet of the 6MN pond. This is proving effective in keeping the material away from the south east side of the pond. TCC has graded the 6MN pad where snow was pushed this past winter. This grading looks good. Dirt that had been pushed off the 6MN pad on the Northwest side adjacent to the shaft heater propane tank still needs to be pushed back with in the pad drainage perimeter. Haul roads & access roads throughout the site are in good condition. Grading to establish good drainage is still needed to the south of Wash Plant 11 (New Wash Plant). Road drainage from Haul Road B runs into Foidel Creek near pond B with minimal settling of the sediment form the roadway. Rock check dam in this location still needs clean out. Processing Waste: The refuse pile is dry and actively having additional waste material placed on it. TCC has begun to grade out the center portion or the pile where material had been piled through the winter months. This work is progressing nicely. East facing slopes of the waste pile look good. Hydrologic Balance: Ponds throughout the mine site were holding water. TCC removed the pump from the 6MN pond last week according to the operator. TCC is working with the CDPH&E to permit this pond with an outfall point. This change to the pond configuration will also need to be permitted with DRMS. TCC needs to continue to clean up and monitor this spill. There was no sign that Hydraulic oil escaped the 6MN pond. Ditches through out the mine site are in good condition. The breach in the Refuse Pile West ditch has been adequately repaired. Seeding of the repair area and temporary water diversion area is needed. No clogged culverts were found. Flows in the ditches are freely flowing through all culverts. 3 of 5 WHITE- File YELLOW-Operator PINK-Specialist
