Storm water was also pumped <br />from the construction areas into the phase IV leach pad. <br />B) Best Management Practices <br />Best Management Practices are being observed throughout the Phase 5 VLF Project. Storm water <br />controls were maintained throughout the week. <br />IV)VLF Geosynthetics <br />A) Geomembrane Installation <br />1) VLF <br />Geomembrane installation within the Phase 5 VLF continued at the beginning of the week, <br />performing deployment, seaming, and repair /QC activities. Geomembrane installation was <br />performed in the area shown on Figure 3. Approximately 52,964 square feet of 100mil LLDPE <br />geomembrane was deployed using a John Deere 200 excavator and a John Deere 544 front -end <br />loader with spreader -bar attachments. Subgrade was inspected and approved by AMEC and <br />Lonestar representatives prior to geomembrane deployment (see Figure 3). Approximately <br />2,684 linear feet of seam was fusion welded during deployment using up to three fusion <br />welding machines. Six destructive test samples were marked during fusion seaming. All <br />destructive sample test results met project specifications. Non - destructive testing was <br />performed for all fusion welded seams. Repairs were performed using the extrusion welding <br />method for all marked defects. Vacuum testing was performed for all extrusion welded seams <br />and repairs. All testing performed met the required project specifications. <br />B) Geomembrane Acceptance <br />1) VLF <br />Primary 100mil (P -180 thru P -289) geomembrane shown on Figure 4 was inspected by AMEC <br />and Lonestar representatives and found to be installed within project specifications and <br />acceptable for continued construction activities. <br />C) Geomembrane Delivery <br />1) VLF <br />No geomembrane was delivered to site during the week. <br />VLF Weekly Report WE 08.14.10.D <br />
