COMMENTS
A complete inspection was conducted by Rob Zuber of DRMS from September 30, 2014 to October 2, 2014. The
Colowyo employee who participated in the field inspection was Kurtis Blunt. Lee Sampson, Marry Stearns, and
Tony Tennyson participated in office discussions. The weather was variable, with snow and rain on October 1st.
The ground was very muddy and precluded access to a good part of the site. The two days preceding the
inspection also experienced rain.
In the South Taylor Pit, the 103 dragline is filling in the east end of pit, the 115 was idle, and the F6 overburden
was being drilled.
In the West Pit, the east side was being prepared for the movement of the highwall miner to this location in the
near future.
BACKFILL and GRADING — Rule 4.14
Contemporaneous Reclamation 4.14.1; Approximate Original Contour 4.14.2; Highwall Elimination 4.14.1(2)(f);
Steep Slopes 4.14.2, 4.27; Handling of Acid and Toxic Materials 4.14.3; Stabilization of Rills and Gullies 4.14.6:
In the West Pit, spoil was being moved with dozers, the 114 shovel, and trucks from a nearby area
(approximately a quarter mile north of the pit) to the east end of the pit.
In the South Taylor Pit, the 103 dragline is still filling in the initial cut (east end of pit).
EXCESS SPOIL and DEVELOPMENT WASTE — Rule 4.09
Placement; Drainage Control; Surface Stabilization:
The West Taylor Fill was viewed from above, toward the southeast corner. No erosion or other problems
were identified with the fill. Most of the topsoil that had been stockpiled has been spread; a small portion was left
to tie into the side channel.
FISH and WILDLIFE — Rule 4.18:
Many elk, deer, and antelope were seen in the reclaimed East Pit, as well as other parts of the mine site.
