The inspection was performed by <br />myself John Effinger III, a registered professional engineer m 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; inchrding 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 check for structural <br />weakness, erosion, other hazardous conditions and idertify required maintenance and to <br />satisfy the requirements of Rule 4.05.6 (13) of the Cobrado Mined Land Reclamation <br />Board for Coal Mining.

Most of the site was traversed by hiking trips over, across and around the <br />structure. The following is a staternert of my professional observations and conchuions <br />from this inspection: <br />The entire pond was examined for structural weakness, erosion, and other <br />hazardous conditions; At this inspection, a large crack b the north dam wall was <br />observed on top. The crack in the soil is about 1 inch thick and ten to fifteen feet <br />long. The crack is in the south face of the top of the dam, near the outlet structure. <br />The pond was dry and contained no water at the time of this inspection. <br />Tumbleweeds in outlet pipe have thickened. <br />Small erosion rill on south bank. <br />
