A number of compaction and moisture content tests were taken oa the <br />stockpiled materials for contractors information. We also observed and discussed the surface drainage <br />conditions along the stockpile with the contractor and Karl Koehler. The contractor advised us that <br />[hey were not placing nay compacted lifts and [hat [hey were going [o stockpile the materials until [he <br />exposed materials had a chance to dry out. <br />At the time of our visit on Jtme Z5, 1997, the contractor had reprocessed the exposed materials iv <br />Areas 1 and 2 and had begun [o place additional fdl materials in these areas. Five compaction tests <br />were taken and the materials being placed in [he waste coal pile appeared [o be compacted to the <br />project speafications. The test results taken on this date are attached. We also met at the site with the <br />surveyors on June 26, 1997 to help establish a grid system oa the pile so that more accurate locations <br />and elevations of [he compaction tests can be recorded. <br />(970) 879.7888 • Fax (970) 879-7891 <br />29585 U.S. 40 West, Box 775226 • Steamboat Springs, CO 80477 <br />
