Hayes <br />Reclamation Specialist <br />Colorado Mined Land Reclamation Division <br />215 Centennial Building <br />1313 Sherman Street <br />Denver, CO 80203 <br />Re: Lower Refuse Pile - January, 1989 Proctor Test <br />Dear Matt: <br />Per your letter to Dennis Conn of December 22, 1988, <br />West Elk Coal Company (WECC), performed a Proctor <br />test on material obtained from the most current <br />working surface of the Lower Refuse Pile. Attached <br />are the results, dated January 26, 1989. <br />In comparison, the Proctor test results are almost <br />identical to the results WECC had been using to <br />calculate compaction of the refuse pile. (See the <br />results dated July 21, 1986, attached.) Other <br />previous Proctor test results, attached, are also <br />similar. <br />As Dennis had mentioned to you earlier, the higher <br />compaction test results are probably due to those <br />random sample points being located in truck and loader <br />traffic areas. Samples from truck roadways developed <br />on the pile, for example, have been known to produce <br />compaction results greater than the ASTM standards. <br />WECC will continue to monitor the compaction results; <br />and if unusually high or low, consistent test results <br />occur, we will evaluate the compaction methods <br />utilized and determine if another Proctor test is <br />warranted. <br />Please don't hesitate to contact me or Dennis Conn <br />should you have questions. <br />Sincerely, <br />Kathleen G. Welt <br />Environmental Engineer <br />xc: J. L. Coffey <br />D. P. Conn <br />AMCO-fi?Oa <br />
