NORTHWEST COLORADO CONSULTANTS, INC. <br />Project: Waste Coal Pile Project No.: 95-2296 <br />Location: Foidel Creek Mine Report No.: 22 <br />Client: Bower Brothers Construction <br />Work Pertorrned: <br />Date: 6/25/97 <br />Time: 3.5 <br />Mileage: 40 <br />Engr.lTech: JK <br />As requested, we visited the project site on this date to conduct nuclear density test No.'s 91 through 95 on the <br />material previously placed. <br />Bower Brothers Construction crews placed and compacted processed waste coal on area #1 and on the east <br />bench of area #2 of the waste coal pile. We obtained 5 samples of material from test sites for moisture content <br />and Checkpoint Proctor determination. All Checkpoints matched Proctor No. 2 from this project. <br />Remarks: <br />The material tested generally met project specifications with compaction ranging from 92% to 100+% and moisture <br />contents ranging from 3.9% below to 0.3% above optimum. We observed that materials placed in the areas tested <br />appeared to be consistent in regards to compaction and moisture content. <br />Please refer to the attached sheet for results of today's testing. <br />Verbal Discussions: <br />Bud Bower of Bower Brothers Construction was notified of today's test results. He advised us that they had not <br />reworked or recompacted the failing areas in the vicinity of test #84 which was taken on 8/5/96. Due to heavy <br />snows and rains the contractor was not able to access this portion of the pile. <br />
