Cripple Creek & Victor Gold Mining Company <br />Laboratory Liner Extension <br />Final Report ameO <br />Quality Assurance Monitoring &Test Results <br />January 14, 2014 <br />4.0 GEOSYNTHETICS CQC SUBMITTALS <br />Geosynthetic CQC submittals have been reviewed by AMEC including installation <br />personnel resumes, geomembrane resin certificates, geomembrane roll certificates, <br />and welding rod certificates, GCL certificates, and geotextile certificates. AMEC's <br />inventory control documentation tracked the CQC certified status of each roll of <br />geomembrane received; this document is presented in Appendix G. All geosynthetic <br />material used met project specifications. <br />4.1 Geomembrane Installation Personnel Resumes <br />AMEC reviewed the resumes of Lone Star installation personnel to verify that the <br />installation superintendent and the seaming personnel possessed sufficient experience <br />as required by the project specifications. Review of the installation personnel resumes <br />indicated that key personnel had experience sufficient to meet or exceed project <br />specifications. Geomembrane personnel resumes are presented in Appendix G.1. <br />4.2 Geomembrane CQC Documents <br />CQC documents submitted by GSE included resin supplier certificates, geomembrane <br />manufacturer resin certificates, geomembrane roll certificates, and welding rod <br />certificates. AMEC reviewed CQC documents prior to geomembrane placement and <br />verified that the documentation was complete and the material properties and CQC <br />testing frequency required by specifications were met. <br />4.2.1 Resin CQC Certificates <br />LLDPE polymer raw material (resin) CQC certificates were provided by the resin <br />manufacturer, Chevron Phillips Chemical Company, at a frequency of one per rail car. <br />AMEC reviewed these certificates prior to geomembrane placement. The <br />geomembrane manufacturer also performed density and melt index tests of the resin <br />supplied by Chevron Phillips Chemical Company to verify material properties prior to <br />geomembrane manufacture. The CQC certificates provided by the resin manufacturer <br />are presented in Appendix G.2. <br />4.2.2 Roll CQC Certificates <br />GSE provided CQC certificates for each roll (approximately every 6,900 square feet) of <br />LLDPE geomembrane used for the project, exceeding the required minimum <br />frequency of one certificate per 50,000 square feet of geomembrane. AMEC reviewed <br />the CQC certificates to verify conformance of the geomembrane to the project <br />requirements. Geomembrane was placed only when complete CQC documentation <br />was provided and AMEC determined test results met or exceeded project <br />specifications. The geomembrane roll CQC certificates are presented in Appendix <br />G.3. <br />sAprojects \1125m -cc &v lab liner extension\h2 - design \lab liner extension \roc report\lab liner roc report.dou 7 <br />
