The CQC <br />certificates provided by the resin manufacturer are presented in Appendix J -3. <br />5.2.2 Roll CQC Certificates <br />Poly -Flex provided CQC certificates for each roll (approximately every 10,000 f�) of LLDPE <br />geomembrane used for the project, exceeding the required minimum frequency of one per <br />50,000 square feet of geomembrane. Golder reviewed the CQC certificates to verify <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 J-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 welding material used on this project was <br />produced from two batches of resin. Golder's review of the CQC certification indicates that the <br />resin used to manufacture the welding material met project specifications. The welding rod <br />CQC certificates are presented in Appendix J -5. <br />5.3 Geotextile CQC Documents <br />Geotextile used to construct the LDT and Underdrains was manufactured by the Amoco <br />Fabrics and Fibers Company of Austell, Georgia. Quality Control Certificates for the <br />geotextile, which meet the project specification, are presented in Appendix J -6. <br />I 203W4 =CetWB02=3220)A400.04740un.doc Golder Associates <br />
