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. Jerry Nettleton of Twentymile Coal Company accompanied the inspection. The mine is an active underground mine. The weather was very cold with approximately 2" of fresh snowfall overcast in the morning, burning off and sunny as the day progressed. Roads: Roads throughout the mine were frozen and snow packed. Access roads to Fish Creek Borehole, 6MN, 18RT 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. Ditch RDA-le has been shaped at access road to Temporary Clay storage area. This area is snow covered and unable to visually document. Support Facilities: The support facilities and remote facilities were verified on the ground for"Annual Coal Compliance" in conjunction with the Division's RN5 Reclamation Estimate. This summary will be forwarded to TCC once it has been complied. 18RT MAC monitoring is occurring. A crew is on site monitoring the mine atmosphere and installing equipment at the 18RT location. 2 Portable shaft heaters and a propane tank have been brought on the 18RT pad in support of the escape equipment. 6MN area has been plowed and is in good condition. 5 portable heaters have been hooked up at the 6MN shaft. The compressor has been installed on the concrete pad. A shelter has not yet been constructed over the compressor. A propane tank has been hauled to 6MN in support of the shaft heaters. Hydrologic Balance: TCC continues to pump Mine water from 1 ORT 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. A portion 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 has found that this Discharge meets WET test compliance when sampled near Site 900 by the EMD vent fan. TCC is in the process of re- establishing water level monitoring at the 1 ORT boreholes. The current water level monitor has been snagging at about 700 ft below the surface. TCC's last water level measurement at 1 ORT showed approximately 21.7 feet of freeboard below the mine seals. TCC stated that MSHA wants TCC to maintain at least 25 ft. of freeboard in this location. Fish Creek Vent Shaft(FCVS) was not pumping at the time of the inspection. Pit 1 elevation has reached the discharge elevation at Site 7 that is flows to Pond D. Pond D was discharging 0.38 on the staff gauge at the time of the inspection. TCC collected water samples during the inspection. 3 of 6 WHITE-File YELLOW-Operator PINK-Specialist
