Colowyo C-1981-019
19 December 2007
Pg 5/6 �-�
Topsoil (cont.): This multiple "handling" of the topsoil increases the chances that
some of the properties may be compromised. Colowyo must ensure that the topsoil
stripping operations are conducted in such a way that none of the chemical and/or
physical properties are damaged. If the conditions become wet and/or muddy,
Colowyo must suspend stripping operations in order to protect the topsoil resource.
- Tony indicated that the final number of acres that had topsoil spread and were
reseeded this year was 85.6 acres. This includes approximately 25 acres that were
topsoiled but not seeded last year. All of these acres are in the East Pit.
General Mine Plan Compliance: - The 101 dragline is on the East Pit highwall
performing reclamation (although it was not actively working at the time of the
inspection).
- The 102 dragline was in the West Pit removing overburden on the F-Seam.
- The 103 dragline was in the West Pit removing overburden on the B-Seam.
- The 114 shovel operation was currently working on removing the A-Seam
overburden in Taylor Draw.
- The 115 excavator was removing X-Seam overburden in the X-Pod area. This is the
area at the south edge of the Section 16 Pit that was approved for mining with the
approval of Technical Revision 65. The operator was also removing X-Seam coal
from this area. This is the last of the X-Seam coal at the mine, as all of the X coal has
been mined from the West Pit.
- The operator was removing and hauling F-Seam coal from the West Pit at the time
of the inspection.
- The operator was drilling and loading explosives in the B-Seam overburden for a
shot.
- The operator had a contractor (Krule) working in the West Taylor drainage, around
the location of the West Taylor fill removing and burning the trees in advance of the
topsoil stripping operations. This operation has finished. The operation did a good job
of removing the trees and leaving the topsoil in good condition.
- Kiewit has completed the large water tank bench and the ready-line for the haul
trucks. Bower had some of their CAT 773's parked there at the ready line at the time
of the inspection. This ready line will be used for the South Taylor Pit, as the other line
is at the north end of the mine.
- The mining at the Colowyo Mine appears to be progressing as discussed and
approved in the PAP.
Fish and Wildlife: - There was a small herd of elk on the large topsoil pile just east of
the work are pond (just below the facilities area). There were also signs of very heavy
use of many of the other areas of the mine, although few animals were seen at the
time of the inspection.
- There were two dead elf along the haul road to the Gossard Loadout. These
animals were hit by haul trucks.
