All geosynthetic <br />material used as part of the LOB construction met project specifications. <br />5.1 Geomembrane Installation Personnel Resumes <br />AMEC reviewed the resumes of Lonestar installation personnel to verify that the installation <br />superintendent and the seaming personnel possessed sufficient experience as required by the <br />project specifications. Review of the installation personnel resumes indicated that key <br />personnel had experience sufficient to meet or exceed project specifications. Geomembrane <br />personnel resumes are presented in Appendix 1 -2. <br />5.2 Geomembrane CQC Documents <br />CQC documents submitted by Poly -Flex included resin supplier certificates and geomembrane <br />manufacturer resin certificates, geomembrane roll certificates, and welding rod certificates. <br />AMEC reviewed CQC documents prior to geomembrane placement and verified that the <br />documentation was complete and that the material properties and CQC testing frequency <br />required by specifications were met. <br />5.2.1 Resin CQC Certificates <br />LLDPE polymer raw material (resin) CQC certificates were provided by the resin manufacturer, <br />Chevron Phillips Chemical Company, at a frequency of one per rail car shipment. AMEC <br />reviewed these certificates prior to geomembrane placement. The geomembrane manufacturer <br />also performed density and melt index tests of the resin supplied by Chevron Phillips Chemical <br />Company to verify material properties prior to geomembrane manufacture. The CQC <br />certificates provided by the resin manufacturer are presented in Appendix 1 -3. <br />5.2.2 Roll CQC Certificates <br />Poly -Flex provided CQC certificates for each roll (approximately every 6,900 ft2 for 100 -mil and <br />every 8,625 ft2 for 80 -mil) of LLDPE geomembrane used for the project, exceeding the required <br />minimum frequency of one per 50,000 square feet of geomembrane. AMEC reviewed the CQC <br />certificates to verify conformance of the geomembrane to the project requirements. <br />Geomembrane was placed only when complete CQC documentation was provided and AMEC <br />SAPROJECTS \1125E CCV CQA \H3 - CONSTRUCTION \LOB CERT REPORT\REPORT BODY\LOB CERT REPORT 2009.07.01.DOC 15 <br />
