ameO <br />■ Observation and documentation of field seaming; <br />■ Identification of destructive seam sample test locations, observation of destructive seam <br />sample testing, and documentation of test results; <br />■ Observation and documentation of geomembrane repairs; and, <br />■ Observation and documentation of non - destructive pressure testing of fusion seams and <br />vacuum testing of extrusion seams and repairs. <br />The following sections present a detailed description of each of the above activities. <br />6.2.1 Conformance Testing <br />Geomembrane manufactured by Poly -Flex. An AMEC representative performed geomembrane <br />conformance sampling at the Poly -Flex plant in Grand Prairie, Texas. Samples were sent to <br />TRI /Environmental, Inc. geosynthetic laboratory in Austin, Texas, for conformance testing. <br />Geomembrane rolls were not used on the project unless approved by AMEC based on <br />conformance test results. <br />The geomembrane used was manufactured along with the Phase 5 geomembrane and the <br />conformance testing frequency was met. Prior to the geomembrane arrival to site, TRI <br />performed 39 conformance tests at a frequency of one test per 138,221 square feet, exceeding <br />the minimum specified testing frequency of one test per 150,000 square feet. Conformance 80- <br />mil single sided texture LLDPE geomembrane used to construct the LOB Liner Extension <br />composite liner system met specifications. Conformance test results are presented in Appendix <br />G. <br />6.2.2 Deployment Monitoring <br />Geomembrane panel deployment monitoring performed by AMEC included: <br />■ Observation of panel surface condition and panel overlap; <br />■ Assignment of panel numbers; <br />■ Verification of factory roll number and receipt of complete certification prior to allowing <br />deployment; <br />■ Measurement of sheet thickness; <br />16 <br />
