The inspection was performed by <br />myself, 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 ensure that proper <br />construction and maintenance techniques were being utilized in accordance with the <br />approved refuse disposal plan and to satisfy the requirements of Rule 4.10.2 (1) of the <br />Colorado Mined Land Reclamation Board for foal Mining. In addition to the on site <br />inspection referenced above, actions taken in preparing this certification included review <br />of the results of field compaction testing performed by your consultant, Kleinfelder, Inc., <br />dated September 1 S, 1998, review of the re-evaluated stability analysis performed by your <br />consultant Terra Matrix, dated December 9, 1996, and review and discussion of.several <br />applicable mine maps and state regulations with yourself at your mine site otFice. <br />Said inspection was performed on a mild (80°), clear Wednesday morning by <br />myself. Most of the site was traversed with a'inotorcycle with frequent stops and hiking <br />trips over, across and around the pile. The following is a statement of my professional <br />observations and conclusions from this inspection: <br />The entire pile was examined for any failures and none found. <br />The entire pile was checked for any springs or seeps and none found. <br />
