III. COMMENTS - COMPLIANCE
Colowyo C-1981-019
28 Jan 10 �
Pg 1/3
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 28 January 2010. Ryan Pawlowski of CCC
accompanied me on the inspection. The weather was cold and snowing and there
was approximately 3-6 inches of snow on the ground at the time of the inspection
(from the current snow as well as from previous snow storms). The mine was not
operating at the time of the inspection as all equipment was down for routine
maintenance (including coal haulage to the loadout).
Roads: - The main haul road/access road was covered with snow at the time of the
inspection. The road is a paved road and was in good condition.
- Colowyo has almost completed the new South Taylor haul road (approved through
Technical Revision 76). The remaining work includes establishing a crown on the
road, ensuring that the road is the proper grade and width for its entire length and
surfacing the road. Colowyo is currently using the South Taylor Haul Road and the
remaining items must be completed and the road certified by a registered,
professional engineer. The haul road is partially an in-pit road (the portion that is
within the limits of the West Pit) and partially a haul road that must be designed and
certified pursuant to Rule 4.03.1 . Upon completion of the haul road Colowyo must
certify the road pursuant to Rule 4.03.1(1)(d)(1) and provide the Division with a
construction report and an as-built map of the road.
- With the construction of the South Taylor Haul Road the majority of Haul Road A and
all of Haul Road B have been removed from use for the mining operations. Portions
of these roads remain open for access to the north side of the final cut of the Section
16 Pit and the East Pit. These portions of the road were covered with snow but
remained stable and in good condition.
- The in-pit road to the overburden dumps in the Taylor Fills and the Section 16 Pit
area were covered with snow but remain stable and well maintained.
- The roads in the Gossard loadout were all well maintained and stable at the time of
the inspection.
Hydrologic Balance: - The Gossard Pond (NPDES 003A) contained water
approximately two feet below the discharge pipe and was not discharging. The
pond embankment was covered with a small amount of snow but remains well
vegetated and stable. The concrete sump at the inlet of the pond has done a good
job in keeping sediment out of the pond.
