A CAT 320 excavator, a CAT 330 excavator, <br />a CAT 950 front -end loader, and tandem -axel haul trucks were used to excavate, haul, and <br />process the material. <br />III) Storm Water Management Structures <br />A) Control Structures <br />No work was performed during the week. <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. Precipitation was not substantial throughout the <br />week. Storm water controls are being observed in the 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 83,097 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 />4,569 linear feet of seam was fusion welded during deployment using up to three fusion <br />welding machine. Twelve destructive test samples were marked during fusion seaming <br />Approximately 201 linear feet of seam was extrusion welded during using up to two extrusion <br />welding machines. Three destructive test samples were marked during extrusion 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. <br />VLF Weekly Report WE 07.24.10.D <br />
