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 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 Coal Mining. In addition to the on site <br />inspection referenced above, actions taken in preparing this certification included review <br />of the results of Proctor and field compaction testing performed by your consultant, <br />Lincoln DeVore dated March 19, 1997, review of the re-evaluated stability analysis <br />performed by your consultant, Terra matrix, dated December 9, 1996, and review and <br />discussion of several applicable mine maps and state regulations with yourself at your mine <br />site office. <br />Said inspection was performed on a cool and sunny Wednesday morning by <br />myself. Most of the site was traversed with a four wheel drive vehicle with frequent stops <br />and hiking trips over, across and around the pile. The following is a statement of my <br />professional 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 />
