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 lieu of bi-annual field <br />compaction testing performed by your consultant, Lincoln DeVore, compaction was <br />monitored during this inspection with a "proof-rolling" observation of the active pile. In <br />addition to the on site inspection referenced above, actions taken in preparing this <br />certification included review of the re-evaluated stability analysis petformed 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 office. <br />Said inspection was performed on a cool (53°), mostly sunny Tuesday 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, very little <br />standing water was observed. <br />
