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 field portion of the
inspection. The Foidel Creek Mine is a large active underground mine. The weather was warm and dry
during the inspection. The operator indicated that the weather has been warm and dry the last several
days.
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.
The water truck was not observed watering roads, but roads were not dusty.
Hydrologic Balance: TCC was not pumping from TORT at the time of the inspection. According to
mine personnel,this location has not been turned back on since pumping ceased in May. TCC is
investigating a long term solution to water treatment from the 1 ORT borehole. Current water handling
found that TCC was Discharging at FCB (site 115). Brian indicated that 7/14 the conductivity of the
Site 115 discharge was approx. 600 µs. Site 115 Flow measured 0.22 on 8" flume. Discharge was
relatively clear. FCVS was pumping to Pit 1. Water was being pumped to the barricade chamber from
10 RT.
Channeling of the ditch on the Barricade chamber pad has occurred. This appears to be a result of
ground squirrel or marmot burrows. TCC needs to seal this hole, and the animal burrows, and assure
that water flows as designed.
6MN reservoir is holding runoff water. As-built certification for 6MN Reservoir has not been provided
to DRMS yet. TCC has not yet installed the pumping facilities at the 6MN reservoir. TCC indicated that
once piping and pump installation is complete the As-built certification will be prepared. This
certification will need to be provided to DRMS and on file at the mine. Stabilization seeding is needed
on the outslopes of the 6MN reservoir.
Ponds inspected included Pond F, Pond G, Pond E, C, B, T, D and 6MN pond. Pond D was
discharging, and water was flowing from Pit 1 to Pond D. Pond D discharge measured 0.32 on 12"
flume. The effluent was clear and numerous minnows were swimming in the effluent. Pond B was
discharging clear, estimated tickle of 0.01 on the staff gauge. The oil booms need to be replaced but no
oil sheen was discernable on the water surface. Pond T was discharging at a trickle.
Processing Waste: The RDA 100-year ditch on the north side of the pile has yet to be cleaned. Drainage
still runs out of the rip-rapped channel and down the east slope, but all drainage from the refuse pile still
is directed to Pond D. This ditch needs immediate clean out. TCC has met with contractor to take care
of this location. it
