Conswction <br />595 Taylor Street <br />Craig, CO 81625 <br />Attu: Mr. Bud Bower <br />Job No. 95-2296 <br />Subject: On-site Inspection, Waste Coal Area, <br />Foidel Creek Mine, Rou[[ County, Colorado. <br />Geademen, <br />Ill IIIIIIIIIIIIIIII <br />RECEIVEp <br />SEP 14 1995 <br />Division of Minerals 8 Geo+o9Y <br />As requested, Northwest Colorado Consultants, Inc visited the project site on August 25, 1995 to <br />observe and inspect [he portion of [he Coal Waste Area which had been stripped of topsoil. <br />The area of topsoil which had been recently stripped is an area approximately 300 to 5(10 feet wide <br />(east-west direction) and 1400 to 1600 feet long (north-south direction). According to the staking in <br />the field and our conversations with Bud Bower, it is our understanding that the stripping has been <br />completed to the 6900' contour level. The areas which had been stripped and inspected aze shown on <br />the attached Figure #1. <br />It appeared that approximately 18 to 7,4 inches of topsoil had been removed and the soils exposed in <br />the base of the excavations generally consisted of clays and/or weathered shale bedrock. We did ao[ <br />observe any groundwater seepage in the stripped areas. In addition, we did no[ observe any signs of <br />unstable slopes in or above the areas stripped. <br />Based on our observations, we believe [hat the portions of the waste coal pile which are noted above <br />have been adequately stripped of topsoil and [he construction of the drainage systems can now be <br />started in this area. <br />It should also be noted that we have also observed the placement of the waste coal materials in the pile <br />during the inspections completed far the topsail removal and drain installation. Based on our <br />observations and the compaction test results, which are attached, we believe that the contractor is <br />placing the waste coal Fill materials in general accordance with the project spermcations and plans. <br />(970)879.7888 • Fax(970)879.7891 <br />29585 U.S. 40 West, Box 775226 • Steamboat Springs, CO 80477 <br />
