Colowyo C-1981-019 <br />16 October 2007 <br />Pg 6/6 <br />General Mine Plan Compliance (cont.): -The operator has a contractor (Krulej <br />working in the West Taylor drainage, around the location of the West Taylor fill. Krule <br />is removing and burning the trees in advance of the topsoil stripping operations. They <br />are using a CAT D6 dozer to knock over the trees and they are loading them into <br />incinerators with a CAT 321 excavator with a claw attachment and a logging skidster. <br />The incinerators are the size of a dumpster and they force air onto the burning trees, <br />providing oxygen for a complete burn. There is very little smoke once the process <br />begins. Prior to lighting the incinerators, the contractor is removing the topsoil and <br />digging a narrow trench for the ashes. Currently Krule has four incinerators on site <br />and is on schedule. There were no problems noted with the Krule operation at the <br />time of the inspection. **See pictures of this area at the end of this report** <br />- Kiewit has been making a large bench for a water tank (for watering the roads, <br />ultimately) and aready-line for the haul trucks, since the other one is north of the East <br />and West Pits. The earthwork has been completed and the area appears to be <br />stable and well compacted. They have the water tank in place and much of the <br />structures for the ready line. There were no problems noted with the Kiewit operation <br />at the time of the inspection. **See pictures of this area at the end of this report** <br />- The mining at the Colowyo Mine appears to be progressing as discussed and <br />approved in the PAP. <br />Excess Spoil: -The reclaimed portions of the West Pit spoil pile were well vegetated <br />and appeared to be stable at the time of the inspection. Runoff from this portion of <br />the pile goes into the West Pit pond. No erosional problems were noted of the pile at <br />the time of the inspection. The upper portion of the pile is truck-dumped spoil. This <br />part of the pile appeared to be stable at the time of the inspection. The reclamation <br />plan calls for the top 75 feet of this pile to be hauled to the West Pit to achieve AOC. <br />-The Streeter fill was appeared to be stable at the time of the inspection. No <br />erosional problems were noted on the fill. This pile has gone through a Phase II bond <br />release. The fill was well vegetated at the time of the inspection. <br />-The Section 16 fill was appeared to be stable at the time of the inspection. No <br />erosional problems were noted on the fill. This pile has gone through a Phase tl bond <br />release.
