APR O 3 199e <br />Mr. Alan Weaver Division of Minerals & Geobgy <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 (4th Quarter, 1997) <br />Dear Al; <br />On December 18, 1997, an inspection was conducted on the Sedimentation Pond <br />No. 1 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 stivctures; 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 Mmed 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 (49°), cloudy Thursday mid-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 />Incised pond with nearly vertical side slopes. <br />The entire pond was recently cleaned and sediments removed. <br />Existing water level was approximately 18" to 24" deep. <br />
