amecy <br />placement holding the high volume collection piping in place, removing debris/sandbags, and <br />assisting the dozer operator with lift thickness. All DCF was placed on previously approved <br />primary geomembrane. AMEC field representatives monitored the DCF placement constantly. <br />III) Storm Water Management <br />A) Best Management Practices <br />Due to heavy rainfall, erosion of the Phase 5 VLF east slope was observed. Sediment reported to <br />the bottom of the Phase 5 PSSA. Ames continued remediation by installing silt fence, maintaining <br />existing silt fence, re-grading slope, removing silt and pumping water from the construction areas <br />into the Phase IV VLF. Sediment was placed on the PSSA east slope to allow the material to dry. <br />IV) Material Processing <br />A) Drain Cover Fill Process Area <br />Processing of Drain Cover Fill (DCF) continued at the DCF process area using a CAT D-9 dozer. <br />Location This Week Cumulative Comments <br /> ula <br />DCF Process 11,944 121,223 <br />Total 11,944 121,223 <br />V) VLF Geosynthetics <br />A) Geomembrane Installation <br />1) VLF <br />Geomembrane installation within the Phase 5 VLF continued performing deployment, seaming, <br />and repair/QC activities. Geomembrane installation was performed in the area shown in Figure 3. <br />Approximately 117,133 square feet of secondary 100mil LLDPE was deployed using a John Deere <br />200 excavator and a John Deere 544 front-end loader with spreader-bar attachments. Subgrade was <br />inspected and approved by AMEC and Lone Star representatives prior to geomembrane <br />deployment (see Figure 3). Approximately 5,919 linear feet of seam was fusion welded using two <br />fusion welding machines. Fourteen destructive test samples were marked during fusion seaming. <br />Non-destructive testing was performed for fusion welded seams. Approximately 228 linear feet of <br />seam was extrusion welded using one extrusion welding machine. One destructive test sample was <br />marked during extrusion seaming. Repairs were performed using the extrusion welding method for <br />all marked defects. Vacuum testing was performed for all extrusion welded seams and repairs. <br />B) Anchor Trench <br />1) VLF <br />PSSA anchor trench excavation continued between stations E10+00 (+/-) and E20+50 (+/-) using a <br />CAT 312 excavator and laborers. The anchor trench was inspected by an AMEC field <br />representative and found to be constructed in accordance with design drawings and project <br />specifications. <br />VLF Weekly Report WE 08.21.10.D.docx
