Mr. Wallace H. Erickson Response to August 22, 2011 Hays Memorandum September 9, 2011 Page 14 6. PVI = Point of Vertical Inflection 7. A.D. = Algebraic Difference (between the slope coming in and the slope leaving) 8. K = Rate of vertical curvature (K= Length of Curve /A.D.) 6.4.5 Exhibit E — Reclamation Plan Adequacy Issue No. 27. In the Access Easement Closure section the Applicant states the access road reclamation area will have a side slope not exceeding 1.5(11):1(V) with the exception of the cut slope which will remain at a slope of approximately 0.7:1. In the Final Grading section the Applicant states the maximum graded slope will be 1.5:1 unless otherwise noted and evaluated. Please provide a stability analysis evaluation in accordance with Rule 6.5 demonstrating the long term stability of the proposed 0.7:1 slope. Response to Adequacy Issue No. 27. See supra Response to Adequacy Issue No. 4.a. Wildcat will submit any revisions to its proposed Reclamation Plan to address slope stability matters, as necessary, through the Technical Revision or Amendment process. Adequacy Issue No. 28. Regarding Question #27 above, please explain and provide justification for why the cut slope will not be backfilled by the Applicant at the conclusion of the project as part of final reclamation. Response to Adequacy Issue No. 28. Where possible, Wildcat used a 2:1 slope. However, in situations where the grading was particularly steep, the 2:1 slope would catch below the top of the originally proposed grading. Given the constraints on the bottom of the slopes, Wildcat determined it would be better to leave steep slopes than to damage existing wetlands. See also Response to Adequacy Issue No. 27. Adequacy Issue No. 29. Please clarify if the proposed gabion retaining structure will remain after reclamation. Response to Adequacy Issue No. 29. Wildcat will clarify the Access Easement Closure section at Pages 4 and 5 of the Reclamation Plan by adding a bullet to indicate road reclamation activities will include: DEN 97, 591, 784v1 9 -941 GREENBERG TRAURIG, LLP • ATTORNEYS AT LAW • WWW.GTLAW.COM
