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 in Figure 4. Approximately 152,433 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 4). Approximately <br />7,180 linear feet of seam was fusion welded during deployment using up to three fusion <br />welding machine. Thirteen 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 />After reworking of the "F" liner bench, the subgrade was inspected and approved for 80mil <br />(primary) replacement. The geomembrane that was previously pulled back was replaced <br />overlapping the 100mil (PSSA) primary a minimum of three feet. <br />B) Geomembrane Acceptance <br />1) VLF <br />After air testing was performed, the geomembrane in the anchor trench was accepted to allow for <br />backfilling. <br />VLF Weekly Report WE 07.10.10.D <br />
