October 2001 -22- 003-2182.004 <br /> density and melt index tests of the resin supplied by Phillips Chemical Company to verify <br /> material properties prior to geomembrane manufacture. The CQC certificates provided by the <br /> resin manufacturer are presented in Appendix I-3. <br /> 5.2.2 Roll CQC Certificates <br /> Poly-Flex provided CQC certificates for each roll (approximately every 10,000 ft2) ofLLDPE <br /> and HDPE geomembrane used for the project, exceeding the required minimum frequency of <br /> one per 50,000 square feet of geomembrane. Golder reviewed the CQC certificates and verified <br /> conformance of the geomembrane to the project requirements. Geomembrane was placed only <br /> when complete CQC documentation was provided to Golder, and Golder determined that test <br /> results met or exceeded project specifications. The geomembrane roll CQC certificates are <br /> presented in Appendix I-4. <br /> 5.2.3 Welding Rod CQC Certificates <br /> Welding rod certification consisted of resin CQC documents for the resin used to manufacture <br /> the welding material for the Cresson Project. The LLDPE and HDPE welding material used on <br /> this project were each produced from one batch of resin. Golder's review of the CQC <br /> certification confirmed that the resin used to manufacture the welding material met project <br /> specifications. The welding rod CQC certificates are presented in Appendix I-5. <br /> 5.3 Geonet CQC Documents <br /> Geonet used to construct the LDCRS was manufactured by Poly-Flex of Grand Prairie, <br /> Texas. Inventory control documentation and Quality Control Certificates for the geonet, <br /> which meet the project specification, are presented in Appendix I-6. <br /> I\W\2182\EXTERNAL POND"MINALDOC Golder Associates <br />
