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 />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 .vas performed on a mild, partly cloudy Wednesday 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 impoundment was examined for structural weakness, erosion, tears to <br />hypalon lining and other hazardous conditions; none were found. <br />Existing water level was 38" below maximum level line. <br />Perimeter fence and hypalon lining in good condition. Several small tears in the <br />hypalon lining were observed along the north and west sides, well above high <br />water level. <br />
