<br />POWDERSORN COAL COMPANY <br />Pond No. 8 - Roadside South Preparation Plant Area <br />Certification <br />I, Larry M. Reschke, PE 19691, hereby certify that Pond No. 8 <br />located at Powderhorn Coal Company's Roadside South Preparation <br />Plant area meets or exceeds the design requirements of plans <br />submitted to and approved by the Colorado Division of Minerals <br />and Geology. Design information can be found in Appendix WW and <br />Exhibit 20 of our Mining and Reclamation Permit Application No. <br />C-81-041. <br />Installation of the redesigned emergency spillway was done on <br />January 20, 1995. The pond expansion began on June 23, 1995 but <br />was not completed until August 15, 1995 due to high water levels <br />in the pond. The accumulated sediment ice. iie pond was remcved as <br />part of this project to allow a survey of the final contours of <br />the pond. The pond expansion and emergency spillway were <br />excavated below grade and did not require embankment <br />construction. The final dimensions of the pond do not exactly <br />match the design but the capacity of the pond meets design <br />requirements. <br />The attached drawing is an as built topo of the pond. A stage <br />capacity chart is attached to verify its capacity. <br />~~~~~~~~ <br />EAR;: -4 :1995 <br />~iiision^~ans~ Jun~~ n calf <br />~;~u CEL'/,pTo ~I <br />:;rQ-y u •.~ rti <br />3 ~~ 1 mi <br />~ ~N~t f ~a _ i ~_ qs- <br />,,,~.... <br />
