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 />control, 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 hazazdous 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 (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 pond was examined for structural weakness, erosion, and other <br />hazardous conditions; none were found. <br />Incised pond with nearly vertical side slopes. <br />Existing water level was low. <br />Some aquatic plant growth (dormant) along the south face. <br />
