Colowyo C-1981-019
14 July 2009
Pg 3/4
Backfilling and Grading (cont.): - Colowyo has been performing backfilling and
grading operations in the Section 4 area of the West Pit (by the East Taylor Pond),
although they were not working on the area at the time of the inspection. They are
using the 102 dragline to move material into the draw when it is out of sequence in
the West Pit. Currently the 102 is doing work on the new haul road corridor, then it will
return to this area to perform reclamation. The plan is to keep cycling the 102
dragline between the West Pit and reclamation work in this area. It was indicated
that the 102 would be in this area for most of August until it had completed the
scheduled reclamation.
General Mine Plan Compliance: - The 101 dragline is on the East Pit highwall where it
was performing reclamation. It has moved a few hundred feet east since the last
inspection in June.
- The 102 dragline was working on the new haul road in the West Pit. The area it was
working on is the in-pit portion of the road.
- The 103 dragline was working in the West Pit removing B-Seam overburden.
- The 114 shovel operation was in the Taylor Draw area working on opening the area
for the highwall miner, which is scheduled to arrive around the end of July or
beginning of August. They are opening the area at the E-2 Seam. It is anticipated
that the highwall miner will be on-site for approximately three months.
- The 115 excavator was removing C-Seam overburden in the box-cut area of the
South Taylor Pit. They were hauling the overburden to the C-C' underrain of the East
Taylor Fill.
Fish and Wildlife: There was a small herd of pronghorn in the East Pit on the edge of
the reclamation along Haul Road A.
Air Resource Protection: - There was a good deal of dust on the haul roads during the
inspection. Colowyo had a water truck operating but, given the hot, dry weather, it
did not appear to be keeping up.
Excess Spoil: The operator was currently dumping overburden from the South Taylor
Pit in the C-C' fork of the East Taylor Fill. The material is coming from both the box-cut
area as well as the area in Taylor Draw where they are opening up the E2-Seam for
the highwall miner. This fork of the fill has almost reached the bench where the rock
crusher is located. Most of the area south of the rock crusher bench appears to be
at or very near its final topography. The operator is constructing the pile in
approximately 50-foot lifts as described in the approved plan in the permit. Once this
portion of the fill reaches its final topography, the operator will pile approximately 50
million cubic yards of additional spoil material on the fill for final reclamation.
Excess Spoil (cont.): - The Streeter was observed from the Streeter Pond below. The
fill appeared to be well vegetated and stable at the time of the inspection. The
vegetation is unseasonably green for this time of the year due to the continued rain
the area has been getting. The ditch on the north side of the fill appeared stable.
