NORTHWEST COLORADO CONSULTANTS, INC. <br />Project: Refuse Pile <br />Location: Foidel Creek Mine <br />Client: Twentymile Coai Co. <br />Project No.: 99-3983 <br />Report No.: 7 <br />Date: 6/26/02 <br />Time: 4.0 <br />Mileage: 50 <br />Engr./Tech: BDL <br />Work Performed: <br />As requested, we visited the project site on this date and conducted nuclear density test No.'s 210 through 219 <br />on the material being placed in the refuse coal pile. <br />Twentymile Coal Company crews had placed and compacted processed waste coal in Area 1 and Area 2 of the <br />Refuse Pile. We obtained a moisture sample at each test location and a bulk sample of the material was obtained <br />and delivered to our laboratory for checkpoint Proctor determination. The checkpoint matched Proctor No. 3. <br />Remarks: <br />The material tested generally met project the project specifications for compaction with the exception of test <br />numbers 211, 213 and 218. <br />Please refer to the attached sheet for results of today's testing. <br />Verbal Discussions: <br />Dave Wallace and Rick Mills of Twentymile Coal Co. were notified of today's test results. We advised them to <br />scarify and blend the failing areas prior to recompacting them. <br />
