Cripple Creek & Victor Gold Mining Company <br />Mill Site Earthworks Project <br />Final Report ameO <br />Quality Assurance Monitoring &Test Results <br />January 31, 2014 <br />5.0 GEOSYNTHETICS QC SUBMITTALS <br />Geosynthetics QC submittals reviewed by AMEC included installation personnel <br />resumes, geomembrane resin certificates, geomembrane roll certificates, welding rod <br />certificates, and geotextile certificates. AMEC's inventory control, summarizing QC <br />certification received for each roll of geomembrane received for the Project liner <br />system is presented in Appendix 1.1. Geosynthetic material used for the Project <br />construction met Project Specifications. <br />5.1 Geomembrane Installation Personnel Resumes <br />AMEC reviewed the resumes of Lone Star installation personnel to verify the <br />installation superintendent and the seaming personnel possessed sufficient <br />geomembrane installation experience as required by the Project Specifications. <br />Review of the installation personnel resumes indicated key personnel had sufficient <br />experience to meet or exceed Project Specifications. Geomembrane personnel <br />resumes are presented in Appendix 1.2. <br />5.2 Geomembrane QC Documents <br />QC documents submitted by Lone Star to AMEC include resin supplier certificates and <br />geomembrane manufacturer resin certificates, geomembrane roll certificates, and <br />welding rod certificates. AMEC reviewed QC documents prior to geomembrane <br />placement and verified the documentation was complete and the material properties <br />and QC testing frequency required by the Project Specifications were met. <br />5.2.1 Resin QC Certificates <br />LLDPE polymer raw material (resin) QC certificates were provided by the resin <br />manufacturer, Chevron Phillips Chemical Company, at a frequency of one per rail car <br />shipment. Geomembrane used on this project was produced from 16 batches of resin. <br />The geomembrane manufacturer also performed density and melt index tests of the <br />resin supplied by Chevron Phillips Chemical Company to confirm material properties <br />prior to geomembrane manufacture. AMEC verified these certificates prior to <br />geomembrane placement and they are presented in Appendix 1.3. <br />5.2.2 Roll QC Certificates <br />Lone Star provided QC manufacturer certificates for each roll (approximately one <br />every 10,000 square feet) of LLDPE geomembrane used for the project, exceeding the <br />required minimum frequency of one per 50,000 square feet of geomembrane. AMEC <br />reviewed the QC certificates to verify conformance of the geomembrane to the project <br />requirements. Geomembrane was placed only when complete QC documentation was <br />provided and AMEC determined the test results met or exceeded Project <br />Specifications. The geomembrane roll QC certificates are presented in Appendix 1.4. <br />
