Reschke, PE 19691, hereby certify that Cameo Borrow <br />Area No. 1 (CBA 1) Sump located at Powderhorn Coal Company's CBA 1 <br />meets or exceeds the design requirements of plans submitted and <br />approved by the Division of Minerals and Geology. Design <br />information can be found in Appendix AAA, Volume 8, Page AAA-9, of <br />our Mining and Reclamation Permit Application No. C-81-041. <br />Installation of the sump began on May 24, 1994, and was <br />substantially completed that day with more than design volume. The <br />final grading on the sump was not done until clean up of the borrow <br />area on August 24, 1994. The sump was excavated below grade and <br />did not require embankment construction. The final dimensions of <br />the sump do not match the design exactly but the capacities of the <br />sump meet the design requirements. <br />The attached drawing is an as built topo of the pond and a stage <br />capacity chart is attached to verify its capacities. <br />~\ MY <br /> <br />
