Third-party conformance test results <br />for 80-mil LLDPE are presented in Appendix J. <br />3.4.2. Geomembrane Panel Deployment <br />The SLF surface was inspected by the CQA monitor prior to geomembrane deployment, <br />ensuring the surface was free of any protruding rocks greater that 0.75-inches, <br />desiccation cracks greater than 0.25-inches in width or depth, or irregularities (rutting, <br />ridges, indentations, etc.) greater than 0.5-inches. The SLF surface was approved by ECA, <br />JHL, CC&V, and the CQA Monitor prior to and during deployment each day. SLF <br />acceptance forms are presented in Appendix D. During geomembrane panel deployment, <br />the CQA Monitor logged the dimensions of each panel, the roll number used for each <br />panel and measured the thickness of the panel edges. Roll numbers were checked against <br />the site inventory to ensure only approved geomembrane was deployed. Deployment <br />summaries for 80-mil geomembrane are presented in Appendix I.1. <br />3.4.3. Geomembrane Fusion Seaming <br />Double-wedge fusion welding was the primary method of geomembrane seaming for the <br />VLF2 Phase 3 Stage B.1 project. Prior to fusion welding activities, trial-welds were <br />performed by each welding machine and corresponding welding technician combination <br />for each type of geomembrane. The fusion welding trial seam logs for 80-mil <br />geomembrane are presented in Appendix I.2.1. The weld was inspected constantly for <br />insufficient overlap, burnouts, or any other damage caused during the welding process. <br />The CQA Monitor logged the welding machine and welding technician combination, the <br />length of the seam, the direction the seam was welded, time of seaming, the welding <br />machine temperature, and the welding machine speed. Destructive test samples were <br />marked during fusion seaming and are discussed further in Section 3.4.5. Continuity <br />conformance of the seam was also performed using pressure testing methods and is <br />discussed further in Section 3.4.6. The geomembrane fusion welding summaries for 80- <br />mil LLDPE geomembrane are presented in Appendix I.3. <br />3.4.4. Geomembrane Extrusion Seaming <br />Extrusion seaming was primarily used to connect the 80-mil LLDPE to the 80-mil LLDPE at <br />the Stage A connection point. Some extrusion seaming was also used within the B.1 limits <br />as a secondary method to double-wedge fusion welding. <br />Any damage caused to the existing geomembrane at the Stage A connection to the 80- <br />mil LLDPE as it was exposed was repaired with 80-mil LLDPE by completely covering the <br />damaged area with an extrusion welded patch. Prior to extrusion seaming activities, trial <br />welds were performed for each welding machine and welding technician combination for <br />each type of geomembrane. The trial seam logs for the 80-mil LLDPE is presented in <br />Appendix I.2.2. As extrusion seaming was performed, proper techniques were verified
