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. Mr. Brian Watterson of Twentymile Coal Company accompanied the field portion of the
inspection. The mine is an active underground mine. The weather was mild and dry. The snow pack
was melting off.
Roads: Roads throughout the mine were dry and were becoming dusty. The operator called to get a
water truck managing the roads but one had not begun spraying the roads by the end of the first day of
the inspection. Haul Roads remain in good condition. Ditch E-2 east of Wash Plant I needs spring
maintenance to remove sediment. TCC needs to check thawed ditches and culverts through out the mine
and remove sediment build up as necessary.
Pond B access road drainage has broken through small check dam and has spilled into Foidel Creek
stream channel. A sediment delta has formed at southern edge of the Foidel Creek drainage. Foidel
Creek is still running low, so little of the sediment has entered the creek. Drainage off Haul Road B
drains to this area. TCC needs to develop a plan to manage the drainage that flows to this location.
The sediment delta is estimated to be approximately 20 ft. x 20 ft. and 0.5 ft. thick. TCC needs to
remove this sediment fan immediately prior to increased flow in Foidel Creek that will flush this material
downstream. 3/18/2009-TCC has an excavator that has removed the majority of the sediment. Sediment
fan was composed of layers of ice & sediment, so actual sediment was less than original estimated. TCC
is bringing a long reach excavator to reach further into cattails to remove more sediment material. Foidel
Creek flow remains north of the sediment delta. TCC is building up the berm on the north side of the
pad. TCC will continue to shape the B access road to direct runoff off the haul road into the sediment
trap on the south side of the Pond B access road. Placement of a culvert at the junction of the roads was
discussed to route flow to the sediment trap. These maintenance operations are acceptable.
TCC has submitted TR66 to the Division for construction of a new access road to the proposed 18L
ventilation site. TCC is procuring a Routt County Special Use Permit for this proposed facilities
location.
Support Facilities: The Train Load Out area has material pushed up into the ditch on the north side of
the pad area. This ditch needs reshaping. Disturbed area boundary markers would help define the edge
of the pad area. Proximity to the stream buffer zone is very close, so clear definition would be advised.
Rock dust tank north of the Facilities has a spill. Material remains in the immediate vicinity of the tanks
but needs immediate clean up.
Hydrologic Balance: TCC was pumping Mine water from TORT to Foidel Creek at a flow of 545 gpm at
the beginning of the inspection on 3/17. By the afternoon of 3/17/09 and morning of 3/18/09 TORT was
not discharging. TCC reported that there was 44.5 ft. freeboard at the TORT borehole. The majority of
the TORT line has been buried. TCC is in the process of connecting the TORT#1 borehole through the
pump house via a buried line. TCC continues to conduct WET testing for this discharge. TCC is
