III. COMMENTS - COMPLIANCE
Colowyo C-1981-019
20 January 2009
Pg 114 1
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 of the Colowyo Mine conducted by Jim Stark of CDRMS.
The inspection was conducted on the morning of 20 January 2009. Ryan Pawlowski
of CCC accompanied me on the inspection. The mine was actively mining coal and
hauling coal to the loadout at the time of the inspection. The weather was very cold
and clear and there were several inches of snow on the ground at the time of the
inspection.
Roads: - The mine access road and haul road to the Gossard Loadout is a paved
road. The road was wet in places from melting snow but was well maintained and
in good condition.
- The light-use road in Taylor Draw to the West Pit Pond, East Taylor Pond and West
Taylor Pond was covered with snow at the time of the inspection. The road
appeared to be stable and well maintained. The road was only open to the East
Taylor Pond. The remaining road to the West Taylor Pond was inaccessible.
- The haul roads in the East and West pit areas were all well maintained and stable at
the time of the inspection. The roads were all dry at the time of the inspection. No
erosional problems were noted on these roads.
- The haul roads in the South Taylor Pit area were all dry at the time of the inspection.
The roads were well maintained and appeared to be stable. No erosional problems
were noted on the South Taylor haul roads.
- The light-use roads around the Gossard Loadout and to the rail loop were wet but
appeared to be well maintained and in good condition.
- Colowyo, through their contractor Anson, has made some upgrades to the small
road spur to the Prospect Pond to facilitate the cleaning of the pond. This work
included increasing the berm height, blading the surface and applying gravel/rock
to aid in stability and reduce the amount of mud tracked onto Colorado Highway 13.
Hydrologic Balance: - The Wash Bay Pond (not a NPDES discharge point) contained
water approximately one foot below the top of the embankment and was not
discharging. This is a total containment pond and discharge into the Work Area Pond
triggers BTEX testing (in addition to regular NPDES testing). The pond embankment
was covered with snow but appeared to be well vegetated and stable at the time of
the inspection. No erosional problems were noted on the pond embankment at the
time of the inspection.
- The Work Area Pond (NPDES 002A) contained water approximately three feet below
the top of the discharge pipe and was not discharging at the time of the inspection.
The pond embankment was well vegetated and appeared to be stable at the time
of the inspection. No erosional problems were noted on the embankment at the
time of the inspection.
