<br />a <br /> <br />1128 MAIN STREET (7191 275-8881 <br />CANON CITY. COLORADO 81212 <br />Energy Fuels Coal, Inc. <br />Mr. Alan Weaver <br />Southfield Mine <br />1190 County Road 92 <br />Florence, CO 81226 <br />~I I I II I I~ I I) II~~ II~ <br />999 <br />RE: CERTIFICATION OF SEDIMENTATION POND NO. 4, SOUTHFIELD MINE, <br />FLORENCE, COLORADO (4th Quarter, 1998) <br />Dear AI; <br />On December 29, 1998, an inspection was conducted on the Sedimentation Pond <br />No. 4 currently in place at your Southfield mine. The inspection was performed by myself, <br />John Effinger III, a registered professional engineer in the State of Colorado since <br />December, 1975. I have experience and knowledge in the design and construction of <br />dams, drainage control, hydrology and structures; including experience in portions of the <br />permitting process of coal mine facilities and permit compliance. <br />The purpose of this inspection and certification was to check for structural <br />weakness, erosion, other hazardous conditions and identify required maintenance and to <br />satisfy the requirements of Rule 4.05.6 (13) of the Colorado Mined Land Reclamation <br />Board for Coal Mining. In addition to the on site inspection referenced above, actions <br />taken in preparing this certification included review and discussion of applicable mine <br />maps and state regulations with yourself. <br />Said inspection was performed on a cool (53°), mostly sunny Tuesday morning by <br />myself. Most of the site was traversed with a four wheel drive vehicle with frequent stops <br />and hiking trips around the pond. The following is a statement of my professional <br />observations and conclusions from this inspection: <br />The entire pond was examined for structural weakness, erosion and other <br />hazardous conditions; none were found. <br />Existing water level was approximately 24 inches below the outlet. <br />
