-2- <br />5) Many of the containment ditches near the topsoil stockpiles <br />appear to exit on steep slopes. The applicant must explain how <br />these areas will be protected from erosion. <br />6) Three maps; exhibits 13-2, 12-2, and 12-4, were noted to have <br />a certification date that predates the map drawing date. <br />7) fhe proposed steep cross slope haul and light use road system <br />contains a number of significant cut slapes and fill embankments. <br />These slopes and fills will require appropriate stability analyses. <br />Cross-sectioniny should be prepared for the critical cut, fill <br />and composite sections. <br />• 8) The applicant should provide supporting data for the 15.3% swell <br /> factor presented within the application, which the applicant <br /> discerned at the nearby Seneca II mine and believes to be <br /> representative of the Seneca II-West mine. The applicant should <br /> analyze the bulking of the entire range of overburden sections <br /> to be encountered, in addition to tyre average section analyzed <br /> within the application as originally submitted. <br />9) The applicant should clearly state whether or not any potentially <br /> affected structures exist within 0.5 miles of the permit <br /> boundaries. If such structures exist, they should be clearly <br /> identified on an appropriate map. <br />~~ lU) If the box cut spoil is proven to be acceptable (not necessary to <br /> achieve approximate original contour within the mined area), the <br /> applicant will have to demonstrate that the proposed placement of <br /> the material will be stable, in compliance with Kule 4.14.2(1)(b). <br /> In addition, the applicant will leave to demonstrate tYiat the <br /> critical road cut slopes and fill embankments can be backfilled in <br /> conformance with the same stability requirements. <br />Furt}rer, the cross-sections presented within EXHIBIT 12 and the <br />Postmining Topography Map do not appear to ayree with the <br />projection of general negative overburden bulking. Significant <br />additional detail will be required to support the proposed <br />Postmining Topography. <br />The above adequacy questions were those noted by Jim Pendleton and <br />myself. Because of the absence of the other review team members, this <br />does not constitute all the adequacy questions noted during the <br />completeness review. The remaining question will be forthcoming. <br />If you have any questions or comments please call Brian Munson or myself. <br />incerely <br />i Herron <br />Reclamation Specialist <br />JH:ys <br />U,~c.
