CO <br />Earth S Environmental <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 />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 156,731 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 />7,757 linear feet of seam was fusion welded during deployment using up to three fusion <br />welding machines. Nineteen destructive test samples were marked during 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 />Panels S216 through S248 and S288 through S356 (secondary- 100mil) were inspected by <br />AMEC and Lonestar representatives, accepting the area shown in Figure 5. <br />C) Geomembrane Delivery <br />1) VLF <br />Five loads (12 rolls each) of 100mil smooth geomembrane were delivered to site during the <br />week for a total of 60 rolls. All loads were delivered on flat bed trucks in good condition. The <br />rolls were unloaded using a CAT 966 front-end loader with forks attached. The geomembrane <br />was placed on three pieces of 4" HDPE pipe, staked two rolls high. An AMEC field <br />representative was present at all times during unloading of the geomembrane. The AMEC <br />representative also inventoried the geomembrane, as it was unloaded. <br />D) Anchor Trench <br />1) VLF <br />Excavation of the anchor trench between stations B9+50 (+/-) and B12+00 (+/-) continued <br />using a John Deere 35D excavator with assistance from laborers. The anchor trench was <br />inspected by an AMEC filed representative and was found to be constructed according to <br />design drawings and project specifications. <br />VLF Weekly Report WE 06.19.10.D
