CENTRAL APPALACHIA MINING, LLC Munger Canyon Mine Coal Mine Waste Bank Certification In accordance with DMG Rule 4.10.2(2), this report is prepared to certify the coal mine waste bank founding and the surface drainage systems were constructed as designed and in accordance with the approved plan. The design of the coal mine waste bank is presented in Volume I of the permit application package, section 2.2.5. Figures 2.2-6 and 2.2-7 show the design of the coal mine waste bank. Preparation of the coal mine waste bank involved; 1) removal of all organic material-and topsoil; 2)-installation ofa surtace drainage-system; and 3} - -- -- salvage and stockpile of coverfill material. The design of the coal mine waste bank does not include a subsurface drainage system. The preparation of the coal mine waste bank began in late September and was completed in early November, 2004. I (J. E. Stover, P.E.) inspected the construction numerous times and have a wide variety of experience in the design and construction of earth fill embankments. There were no steep slopes, seepage or other visible factors which would indicate a potential problem with the coal mine waste bank. The construction of the coal mine waste bank is a phased project. A portion of the founding was cleared of all organic material and topsoil. Topsoil was placed in the designated stockpile area. coverfill was salvaged and placed in stockpile. A temporary upper diversion ditch was constructed. It is not practicable or necessary during this phase of the project to construct all of the design ditches. The remaining ditches will be constructed as the pile expands. It was also not practicable at this time to construct the upper diversion ditch at its ultimate design elevation. The design of upper diversion ditch "A" is presented in Volume II, Appendix M(vii) pages M(vii)-4 & 29. The flow depth is 0.4 feet and the freeboard is 2.5 feet for a total design depth of 2.9 feet. Temporary upper diversion ditch "A" was constructed a total of about 2.0 feet deep with provides 1.6 feet of freeboard which is considered satisfactory for the temporary ditch. To the best of my knowledge and belief, with the exceptions noted above, the coal mine waste bank founding and drainage system were constructed in accordance with the approved plan and meets the requirements of the Regulations of the Division of Minerals and Geology. 4~ R ~G d,~J~ F c'a_ e darroes~.
