(Northwest Colorado Consultants, Inc.) has prepazed this latter outlining our <br />inspections made during the first quarter of 2000 a[ the Waste Coal Area, which is located at the Foidel <br />Creek Mine in Rou[[ County, Colorado. <br />We visited the project site on January 4, 2000 with Rick Mills [o inspect [he waste coal azea. A[ the time <br />of our visit, the contractor was stockpiling the waste coal materials in the central portion of Area 1 of the <br />waste coal azea. They had not placed any compacted lifts since last fall. <br />Based on our recent discussions with Mr. Mills, it appears that approximately 13,000 tons of waste coal <br />were generated and stockpiled in January and approximately 8,000 tons were generated and stockpiled in <br />February, 2000. However, they did not generate nor stockpile any materials in Mazch. It is our <br />understanding that [he majority of [he materials were stockpiled [o the south of the temporary haul road, <br />which runs in a east [o west direction across the pile. Since no additional lifts of refuse had been placed <br />or compacted during this quarter, we did not take any compaction tests. <br />As suggested in our previous quarterly report, the water levels in [he monitor wells installed on October <br />23, 1997 were measured during this quarter on a monthly basis. In addition, [he water levels for the <br />three (3) monitor wells installed on December 9, 1999 aze included. The groundwater elevations <br />measured in the wells aze summarized below. <br />Groundwater Elevations <br />Date South Well North Well RMW 3 RMW 4 RMW 5 <br />10/30/97 6894.5' 6892.3' <br />11/25/97 6891.5' 6887.3' <br />10/1/98 6896.2' 6894.7' <br />10/29/98 6896.1' 6894.7' <br />11/24/98 6897.5' 6894.6' <br />12/30/98 6897.9' 6894.2' <br />01/29/99 6898.1' 6893.8' <br />(970} 879.7888 • Fax (970) 879.789Y <br />2063 Snow Bowl Plaza, P.O.
