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 Foidel Creek Mine is a large active underground mine. The weather was mild, dry and
partly cloudy on the second day of the inspection.
Records: Records were checked at the mine office. Records were updated and in good order. TCC
provided copies of CPDS reports for August 2008 for CO-G072578, Jan. &Feb. 2009 for the same
CDPHE permit number and 41h Quarter 2008 for CO-0042161. TCC could not readily find records for
CO-GO72758 Jan &Feb 2008. TCC contacted CDPHE requesting copies of these reports be sent to
DRMS &TCC. TCC believes that these reports were misfiled. TCC also provided detail regarding the
change in CPDS #for CO-G072272/CO-G072758. Records checklist with comments is include as a part
of this report.
Roads: Haul Roads and access roads throughout the mine are in relatively good condition. Snow melt
and recent precipitation has left some portions of roads muddy, but these areas are limited and roadways
are beginning to dry up. As roads and ditches begin to dry, TCC is reshaping ditches and cleaning
culverts as needed. 6MN access road at the Fish Creek crossing held up well this runoff season. Most
ditches around facilities area are functional. TCC continues to maintain these ditches. TCC was
spraying the haul roads for dust control both days of the inspection.
Hydrologic Balance: Ponds throughout mine are discharging. 6MN pond had been pumped 4/17, 4/18,
and 4/19/2009 to maintain adequate freeboard. Mr. Watterson reported that water samples were
collected as required when discharging 6MN pond. On 4/21/09 6MN pond had approximately 2 '/z ft.
freeboard and the pump was reported to have been shut off the morning on 4/20/2009. 6MN reservoir
has begun to fill with snow melt run off. As-built certification for 6MN Reservoir has not been provided
to DRMS yet. This certification needs to be provided to DRMS and on file at the mine. Current water
level was approximately 5 ft. below the armored spillway elevation. The inspector took several slope
measurements on 6MN reservoir embankments.
East side of embankment: inslope=16°, outslope=20°,
South side of embankment: inslope=20.5°, outslope=19°,
South side of embankment (W) inslope=24°, outslope=25°.
6MN Upland Diversion ditch had a good flow of runoff. Ditch sides are steep. These side slopes need a
gentler grade.
TCC needs to complete hydraulic oil spill at 6MN facilities area. Sump and berm and previous
cleanup efforts appear to have kept the distribution of the oil to the former compressor building area but
final cleanup of this spill needs to happen.
18RT facilities area has also had a spill. Snow is melted off and a hydrocarbon liquid had been spilled
on the N injection hole drill area. Runoff from this drill pad runs into a ditch and then to a sump.
Spilled material has been contained in the sump. There was no evidence of any discharge of water or
hydrocarbon material from the sump. TCC placed absorbent pads into the sump on 4/21 after spill was
discovered. Clean up of the used pads and replacement with fresh pads is needed on 4/22. TCC
