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 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 perforted on a warm and sunny (80°), Tuesday mid-morning <br />by myself. Most of the site was traversed with a four wheel drive vehicle with frequent <br />stops and hiking trips over, across and around the structure. The following is a statement <br />of my professional 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 v,•ater level in the pond v,~as 30" below at the bottom of the pond decant <br />gate. <br />Small erosion rill on east bank has widened slightly at top. <br />
