J Foothill Sanitary Landfill — Module 1 December 2003 County of San Joaquin Job No. 031602.00.02 • Field Panel Placement During the panel placement, Vector's CQA onitor(s) kept panel deployment logs. These logs recorded the location (panel number and roll number), installation schedule (date and time), weather conditions (temperature and wind), and GCL type. These panel deployment logs are presented within Appendix I. To protect the GCL, HDPE liner was deployed concurrently with the GCL placement. Deployment was performed in general conformance with the project specifications. 5.2.3 Defects and Repairs Vector's CQA Monitor inspected all seams and non -seam areas of the GCL for defects, holes, displaced panels, premature hydration, and any sign of contamination by foreign material. All defects were recorded as part of the daily construction report prepared by Vector's CQA Monitor. Appropriate repairs were completed prior to installation of the overlying HDPE material. 5.3 Geomembrane 5.3.1 Geomembrane Material The 60 -mil high-density polyethylene (HDPE) geomembrane manufactured by GSE was used in the liner system for Module 1. 5.3.1.1 Receiving Inspection Upon arrival by truck shipment, the unloading and storage of the geomembrane rolls were observed by Vector's CQA Monitors.
