2002 -40- 003-2203 <br />. of each seam to verify that no additional repairs were required. In the event that additional <br />repairs were needed, Golder mazked the location requiring repair on the geomembrane, <br />documented the location, and brought the repair area to the attention of Poly-Flex. Once <br />Poly-Flex made repairs, Golder checked the repair location to verify completion. Golder <br />inspected all seams for quality and completion. Golder personnel conducted a final <br />walk-through to verify completion of the entire geomembrane system and to identify any <br />additional damage that may have occurred during construction operations, <br />Golder recorded observations made during seaming. The fusion-welding summary is presented <br />in Appendix K-5, and the extrusion-welding summary is presented in Appendix K-6. <br />6.1.4 Defect and Repair Observations <br />Golder inspected geomembrane panels for damage that may have occurred during manufacture, <br />• transport, deployment, or installation as discussed in Section 6.1. Golder repeatedly observed <br />all panels and seams for defects until Ames covered the geomembrane with DCF. <br />Golder documented defects by assigning a unique defect identification code to each defect, and <br />mazking each defect code on the geomembrane. The summary of defects, repairs, and <br />non-destructive testing of repairs, including the approximate location of each repair is presented <br />in Appendix K-7. <br />6.1.5 Destructive Testing <br />Golder selected destructive test locations based on Poly-Flex's completion of approximately <br />78,661 lineal feet of welding, vazious working conditions, and on seaming observations <br />(e.g., suspicion of a defective weld). Poly-Flex obtained and tested 164 fusion seam <br />destructive samples and 9 extrusion seam destructive samples during the installation of the <br />geomembrane in the Phase IVa OSA. <br />t:~oovzos~ooomcw4POSOZwazzza3 oaooaa~aoaca« CaOIdBF AS$OC1Q}e5 <br />
