Memo to Wally Erickson 3 August 2, 2009 <br />Second Review of Access Road Construction File No-, M-2006-069 <br />2. The condition of the retaining timbers and cable, particularly the extreme angle of a formerly upright <br />timber that was embedded 14 feet into the fill, indicate substantial movement of the fill slope since <br />the time of coastmetion. The "As-Build Report" describes mitigation actions but does not provide an <br />analysis of the cause or extent of the instability or the ability of the suggested mitigation to prevent <br />further movement. Such an analysis must be provided for DRMS review. <br />Wildcat Mining must commit to executing the following list of recommendations contained in "As Build <br />Report" and provide a schedule for their completion. All activities trust be confined to areas for which <br />Wildcat Mining has legal right to enter. <br />1. Tree planting to occur in 2010. Wildcat Mining must provide a tree planting plan for DRMS review <br />and approval to be executed if DRMS approves the road. <br />2. Place straw bales at the bottom of the slope along the intersection of the slope with chain link fence to <br />stop loose soil and rock from migrating into the wetlands. This must be done as soon as possible. <br />3. The rock that has moved into the wetlands must be broken up and removed by manpower, not <br />equipment. This must be done as soon as possible. <br />4. All silt fence needs to be repaired, and damaged straw bales be replaced. This must be done as soon <br />as possible. <br />5. The pipe culvert that was installed at station 5+00 needs to be cleaned of debris and a metal grating <br />installed on the upstream inlet of the pipe. The inlet structure shown in Sakura Engineering drawings <br />must be installed. This must be done as soon as possible. <br />6. Provide a sampling and analysis plan for the pond at the toe of the road fill for DRMS review. This <br />must be done as soon as possible. <br />7. Complete final grading, road base, drainage structure and bar ditch. These items may not commence <br />until approval from DFtMS to proceed through issuance of a mined land reclamation permit that <br />includes the road. <br />8. The upside of the road at station 4+40 to 4+60 has loose trees on the top of the slope. They need to <br />be removed and the slope cleaned of loose rock. The vegetation/trees must be removed by hand not <br />powered equipment. This must be done as soon as possible. <br />9. The silt fence on the entrance mad at station 0+00 needs to be repaired and waddles installed on the <br />west side of the silt fence. This must be done as soon as possible. <br />10. All cribbing must be inspected for loose cables and slipped notches. A report of the inspection must <br />be provided to DRMS. This must be done as soon as possible. If and when a mined land reclamation <br />permit that includes the road is issued, areas of concern must be re-excavated, repaired and new fill <br />placed in the excavated voids. The material or new fill must be 3-inch minus well graded with no <br />vegetation in the fill. Compaction must be in excess of 95 percent modified proctor. A geotechnical <br />engineer must oversee the work and provide written certification to DRMS of correct execution, <br />including meeting the compaction specification. <br />11. In the "As-Build Report" Sakura Engineering states the relation of the floodplain to the toe of the fill <br />slope can be field verified using EDM survey equipment and further states that drawings illustrating <br />the relationship could be prepared. This must be done as soon as possible. <br />12. Upon completion of construction of the road, if it is approved by DBMS, As-Built Drawings must be <br />submitted to DRMS.
