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 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 pond was examined for structural weakness, erosion and other <br />hazardous conditions; none were found. <br />Existing water level was 20 inches below the outlet. <br />Outlet & spills were free and unobstructed and should function as designed. <br />No sign of erosion damage. <br />
