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 complete 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 has moved the longwall from the final panel
in the Northern Mining District, to the Western Mining District(WMD). TCC personnel indicated that the
18L and 16L gate roads are being developed and the longwall was not operating at this time. The weather
was cloudy and cold— 17'F. changing to light snow in the afternoon. The mine facilities and roadways
were frozen during the morning,beginning to thaw as the afternoon progressed. Two trains loaded coal on
the first day of the inspection.
Roads: Haul Roads and access roads throughout the mine were frozen, and in good condition. TCC has
constructed the temporary access road to the topsoil stockpile.
Repairs to the waterline alongside the FCBH road have been completed. The repair trench has been
backfilled and graded but was snow covered during the inspection. TCC personnel believed that the
repaired segment had not yet been seeded. Seeding should occur as soon as weather allows.
Topsoil: TCC continues to salvage topsoil from the RDA Expansion area. Equipment was removing topsoil
from the pile at the base of the slope adjacent to an existing Overburden stockpile. Topsoil salvage is going
well. The topsoil stockpile has wattles on the downslope side, and contour furrows above. TCC has
stripped topsoil from the footprint of the proposed Overburden storage area. Topsoil from this footprint still
needs to be transported to the Topsoil stockpile. Sediment control measures appear to be in place. Site is
snow covered with approximately 6"to 18" of snow so details of sediment control were not readily
discernable. TCC removes snow from active work area. Handling of the Diversion ditch crossing over the
stockpile access road was discussed. All runoff reports to Pond D, from both upland and disturbed areas.
TCC is drilling the 6RT underflow borehole near the junction of RCR27 and RCR33. This site had
previously been disturbed by a water monitoring well and the previous location of the county road. Little
topsoil was available for salvage. Topsoil that was available was placed on the west side of the active pad.
Wattles and silt fence were installed and appear functional. Installation of the 6RT underflow pipeline has
not commenced.
Hydrologic Balance:
TCC has not pumped from 1 ORT. The 4"dia. piezometer hole has been completed but TCC is still having
difficulties collecting water level data at this site. They believe that the casing has become magnetized and
is ordering a replacement water meter to collect data at this point. TCC personnel stated that last week there
was 39.48 feet of freeboard at this location in the EMD.
6MN reservoir pump house is under construction. TCC has not provided As-built certifications to the
Division for this reservoir yet. During the inspection crews were trenching the waterline from the 6MN
reservoir to the 6MN Million gallon tank. 6MN sediment pond is frozen and not discharging.
