JUL O 7 2000 <br />Mr. Alan Weaver DivisionotMineralsBGeology <br />Southfield Mine <br />1 ] 90 County Road 92 <br />Florence, CO 81226 <br />RE: CERTIFICATION OF FRESH WATER IMPOUNDMENT POND NO. 3, <br />SOUTHFIELD MINE, FLORENCE, COLORADO (1st Quarter, 2000) <br />Dear Al; <br />On April ]0, 2000, an inspection was conducted on the Fresh Water <br />Impoundment Pond No. 3 currently in place at your Southfield mine. The inspection was <br />performed by myself, John Effinger III, a registered professional engineer in the State of <br />Colorado since December, 1975. I have experience and knowledge in the design and <br />construction of dams, drainage control, hydrology and structures; including experience in <br />portions of the 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 4.05.9 (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 mild (75°), mostly cloudy Monday morning by <br />myself. Most of the site was traversed with a two 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 impoundment was examined for structural weakness, erosion, tears to <br />hypalon lining and other hazardous conditions; none were found. <br />Existing water level was overtopping the pond and spilling over at the North East <br />corner. <br /> <br />Hypalon lining in good condition. Several small tears in the hypalon lining were <br />observed along the north and west sides, well above high water level, and two <br />tears along the south face. <br /> <br />
