Storm water <br />controls were maintained throughout the week. Precipitation was not substantial throughout the <br />week. Storm water controls are being observed in the East Cresson Clay Borrow. <br />V) 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 in Figure 4. Approximately 81,758 square feet of 100mil LLDPE single sided <br />textured and 43,380 square feet of 80mil LLDPE single sided textured was deployed using a <br />John Deere 200 excavator and a John Deere 544 front -end loader with spreader -bar <br />attachments. Subgrade was inspected and approved by AMEC and Lonestar representatives <br />prior to geomembrane deployment (see Figure 4). Approximately 5,155 linear feet of seam was <br />fusion welded during deployment using up to three fusion welding machines. Twelve <br />destructive test samples were marked during seaming. All destructive sample test results met <br />project specifications. Non - destructive testing was performed for all fusion welded seams. <br />Repairs were performed using the extrusion welding method for all marked defects. Vacuum <br />testing was performed for all extrusion welded repairs. <br />B) Geomembrane Acceptance <br />1) VLF <br />Panels S118 through S215 (secondary- 100mil) were inspected by AMEC and Lonestar <br />representatives, accepting the area shown in Figure 5. <br />VLF Weekly Report WE 06.12.10.D <br />
