August 2002 -35- 0003 -2203 <br />• 6.0 GEOSYNTHETIC CQA TESTING AND MONITORING <br />The following sections describe the CQA activities performed by Golder for the geomembrane <br />installed in the Phase Wa Area, and the geosynthetics installed in the LDT and Underdrains. <br />In accordance with the Golder CQA Plan, when a Golder monitor observed deficiencies, the <br />monitor determined the nature and extent of the problem and notified Poly -Flex and/or CC &V. <br />When unsatisfactory test results identified a deficiency, Golder performed additional tests to <br />define the extent of the deficient area. Poly -Flex corrected deficiencies to meet the <br />requirements of the specifications, and Golder retested and/or approved the corrected deficiency <br />prior to any additional related work. The following sections include discussions of the <br />deficiencies encountered. <br />6.1 Ore Storage Area Geomembran►e <br />CQA activities conducted by Golder during the installation of the 80 -mil single -sided textured <br />LLDPE geomembrane in the Phase 1Va OSA consisted of the following: <br />► Conformance sampling and testing of the geomembrane; <br />► Observation and approval of the SLF surface prior to deployment of 80 mil <br />single -sided textured LLDPE geomembrane in the OSA; <br />► Observation and documentation of geomembrane deployment, including <br />verifying sheet thickness and overlap and documenting panel layout; <br />► Observation of trial seam sample testing and documentation of results; <br />► Observation and documentation of field seaming; <br />► Identification of destructive seam sample test locations, observation of <br />destructive seam sample testing, and documentation of test results; <br />► Observation and documentation of geomembrane repairs; and, <br />• <br />l: , x mo3xo400W,atp.epoBO2,=uo;.o400.04740w,&c Golder Associates <br />
