Memo to Wally Erickson 6 August 22, 2011 <br />Wildcat CN -01 Access Road Geotechnical Adequacy Review File No. M- 1981 -185 <br />29. Please clarify if the proposed gabion retaining structure will remain after reclamation. <br />30. In the Access Easement Closure section the Applicant states the road fill including the culvert <br />will be removed. Please confirm all fill material used to construct the culvert fill and out slope <br />of the access road will be removed as part of final reclamation. <br />31. In the Access Easement Closure section the Applicant states the excess road fill will be used to <br />grade the road contours into the existing topography. Please provide a work plan for the fill <br />removal, placement, compaction and final grading for the road reclamation and closure. <br />6.5 Geotechnical Stability Exhibit <br />32. The Applicant submitted the Geotechnical Reconnaissance report prepared by R Squared, Inc. <br />dated May 29, 2010 (Attachment 6.5.3) as the Geotechnical Stability Exhibit. The report does <br />not comply with the requirements of Rule 6.5. Please submit an engineering stability analyses <br />for the access road slopes during operation and final reclamation. The analyses must include <br />models for the fill and cut slopes based on the new geotechnical investigation and the <br />proposed final reclamation slopes. <br />The Applicant has provided an acceptable framework for the access road work plan and has made <br />improvements in the submittal for the access road geotechnical issues. In particular, the CLC <br />Associates construction plans are a significant improvement compared to the Applicant's previous <br />submittals. However, there remain inconsistencies between sections of the R Squared exhibits and <br />contradictions between the CLC designs and R Squared narrative. The issues of inconsistencies, <br />contradictions and the need for the Applicant to perform QA /QC on the application documents were <br />raised by the Division during the June 29, 2011 meeting. The Applicant has shown improvement in all <br />of these area, however additional improvements are require before the Division would consider the <br />application for approval. <br />
