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 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 field compaction testing performed by your consultant, Kleinfelder, Inc, <br />Dated April 6, 2000, 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 office. <br />Said inspection was performed on a hot (90°), cloudy Friday afternoon by myself. <br />Most of the site was traversed with a two wheel drive vehicle with frequent stops and <br />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 was found. The year old <br />slide damage on the North face appears to have stabilized well. <br />The entire pile was checked for any springs or seeps and none found, very little <br />standing water was observed. Lift thickness, material consistencies and placement <br />procedures appeaz to be in compliance with Terra Matrix re-evaluated stability analysis. <br />
