COLORADO 81212 <br />Energy Fuels Coal, Inc. <br />Mr. Alan Weaver <br />Southfield Mine <br />1190 County Road 92 <br />Florence, CO 81226 <br />RE: CERTIFICATION OF SEDIMENTATION POND NO.1, SOUTHFIELD <br />MINE, FLORENCE, COLORADO <br />Dear Al; <br />On June 19, 1997, an inspection was conducted on the Sedimentation Pond No. 1 <br />currently in place at your Southfield mine. The inspection was performed by myself, John <br />Effinger III, a registered professional engineer in the State of Colorado since December, <br />1975. I have experience and knowledge in the design and construction of dams, drainage <br />wntrol, hydrology and structures; including experience in portions of the permitting <br />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 />Boazd 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 warm and sunny Thursday morning by myself. <br />Most of the site was traversed with a four wheel drive vehicle with frequent stops and <br />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" deep. <br />Aquatic plant growth was observed in the northerly end of the pond. <br />Incised pond with nearly vertical side slopes. <br />
