WMU FU-08 October 2008 Forward Landfill Project No. 021605.08 on the north side of the cell, just in the trench area. The modification was done with the approval of the design engineer. The installation and documentation of the two types of materials was the same. Therefore, the installation procedures and testing described below pertains to both material types. 5.3.1.1 Receiving Inspection Upon arrival by truck shipment, Vector's CQA monitor observed the unloading and storage of the geomembrane rolls. Each roll of geomembrane was logged in by roll number and then crosschecked against the quality control documents provided by the supplier. Following the inspection and approval of QC certifications, the material was approved for installation. A copy of the log of geomembrane received is included in Appendix I. The manufacturer's QC data is also included in Appendix I. The inventory logs include the roll existing from the U-06 construction project. The MQC certifications and conformance test results for this material was reviewed and approved during FU-06 construction and the documentation for these rolls is included in the Final Report for FU-06. 5.3.1.2 CQA Conformance Testing Select samples of the HDPE were cut from random rolls of the geomembrane at the manufacturing plant by the third party testing laboratory for conformance testing in accordance with the project specifications and CQA manual. Conformance testing included: • density (ASTM D-1505); • carbon black content (ASTM D-4218); • carbon black dispersion (ASTM D-5596); • thickness (ASTM D-5994); • tensile properties (ASTM D-6693); Vector Engineering, Inc. • 143E Spring Hill Drive•Grass Valley, CA 95945•(530)272-2448 -23-
