(Northwest Colorado Consultants, Inc.) has prepared this letter outlining our <br />observations made during the first quarter of 2001 at the Refuse Pile, which is located at the Foidel Creek <br />Mine in Routt County, Colorado. During this quarter, we visited the project site on March 13, 2001 to <br />provide our quarterly observations. <br />At the time of our site visit on March 13.2001, we met with Mr. Rick Mills to observe the conditions at the <br />Refuse Pile. At the time of our visit, we observed that the ntajoriry of the refuse materials (waste coal) <br />were being stockpiled in Area 1. We also observed that the contractor had stockpiled a considerable <br />amount of waste coal in Area 2 earlier during this quarter, however they had not spread out or compacted <br />any lifts since our last site visit. We were advised that they had produced approximately 22,000 cubic <br />yards of waste coal in January and approximately 14,000 cubic yards in February. <br />It should be noted that we did not observe any adverse drainage or geotechnical conditions at the time of <br />our site visit. Based on our part-time observations, it appears that the waste coal materials that were <br />recently produced, were being stockpiled in general accordance with the project plans and specifications. <br />As suggested in our previous quarterly report, the water levels in the monitor wells installed on October 23, <br />1997 and December 9, 1999 were measured during this quarter on a monthly basis. A graph showing the <br />monthly water levels is attached. ~ <br />This report fulfills the q rte ty inspection requirements as specified by Rules 4.09.1(1 I)(a) and <br />4.10.2(2)(a). If you have y uestions regarding this report or our observations, please contact this office. <br />INC., <br />~b~ '' _ ~---- <br />Binns - ivisMinerals & Geology <br />(970) 879.7888 • Fax (970) 879-7891 <br />2063 Snow Bowl Plaza, P.O.
