r� TABLE 7 GCL CONFORMANCE TESTING SUMMARY SPECS 35(min.) 0.75 @ 0% M.C. 5 x 10'9 (max.) — 7236 52 1.12 2.6 x 10-9 P 7271 52 1.13 2.3 x 10' P 5.2.3 GCL Installation 5.2.3.1 GCL Deployment GCL was deployed on the 5:1 slope, bench, and 2:1 slope over a portion of existing Austin Road Landfill at the north end of the FU -10 floor area. Ausenco Vector CQA activities during GCL deployment include monitoring the installer's activities, filling out field forms for Subgrade Acceptance and Deployment Logs, and producing an as -built map. Field Panel identification: Prior to GCL deployment, the Ausenco Vector CQA monitor and the superintendent for the liner installer, COMANCO, discussed the labelling of the material. It was agreed to the number each separate panel sequentially, including the factory roll number and the days date. Field sketches of each day's deployment were produced and maintained by Ausenco Vector CQA monitor. This information can be found in Appendix 1. Field Panel Placement: The GCL deployed on the 5:1 slope were full panels from the anchor trench to bench, where the GCL was over lapped 7 feet according to the plans. Full panels were deployed from the bench to the bottom of the 2:1 slope. During deployment, granular bentonite was spread along the inside edge of each seam and the GCL overlapped 1 foot according to the requirements in the Plans and Specifications. During GCL deployment, the Ausenco Vector CQA monitor recorded information in the GCL Deployment Logs. Included with these logs are as -built sketches showing the location of each panel of GCL. To protect the GCL from hydration the material was covered the same day as it was deployed with HDPE liner. The GCL panel Deployment Logs are presented in Appendix H. 5.2.3.2 Defects and Repairs During deployment, the Ausenco Vector CQA monitor inspected the seams and non -seam areas of the GCL for defects, holes, insufficient overlap, premature hydration and signs of contamination by foreign material. Defects in the GCL were brought to the attention of the installer to make repairs or corrections as needed. 5.3.1 Geomembrane Material A 60 -mil thick high-density polyethylene (HDPE) geomembrane, manufactured by Agru America, was used in the composite liner system for WMU FU -10. Double -sided textured (DST) liner was deployed on the floor and upper deck areas; single -sided textured (SST) liner was used on the 5:1 -bench -2:1 slope areas.
