ame <br />III) Storm Water Management <br />A) Temporary Erosion Controls <br />Ames continued remediation and installation of silt fence at the east slope of the Phase 5 VLF. <br />This was performed to prevent and control erosion of the slope. Water was also pumped from the <br />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. Storm water controls are being observed in the <br />East Cresson Clay Borrow. <br />IV) VLF Geosynthetics <br />A) Geomembrane Installation <br />1) VLF <br />Geomembrane installation within the Phase 5 VLF continued throughout the week, performing <br />deployment, seaming, and repair /QC activities. Geomembrane installation was performed in <br />the area shown on Figure 3. Approximately 173,344 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 />10,431 linear feet of seam was fusion welded during deployment using up to four fusion <br />welding machines. Twenty 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. <br />B) Geomembrane Acceptance <br />1) VLF <br />After air testing was performed, the geomembrane in the anchor trench was accepted to allow <br />for backfilling (see Figure 4 for previously accepted geomembrane). <br />C) Geomembrane Delivery <br />1) VLF <br />No geomembrane was delivered to site during the week. <br />D) Anchor Trench <br />1) VLF <br />Water and debris were removed from the anchor trench, preparing for deployment of the PSSA <br />primary geomembrane (100mil) and backfilling of the anchor trench. <br />Backfilling of the PSSA anchor trench continued between stations G3 +50 ( + / -) and G11 +50 <br />( + / -). The anchor trench was backfilled using a John Deere 35D excavator, a CAT skid steer <br />loader, and laborers. Soil liner fill was moisture conditioned using a tandem axel water truck <br />and placed in the trench in one -foot compacted lifts. Compaction was performed using a <br />vibratory plate compactor. <br />VLF Weekly Report WE 08.07.10.D.docx <br />
