amecs <br />2) Drain Cover Fill (DCF) <br />Drain cover fill (DCF) placement within the Phase 5 VLF continued. DCF was placed in the <br />area show on Figure 6. The DCF was hauled from the processing area to the placement area <br />using CAT 740 haul trucks. The DCF was placed in a 2-foot lift using a CAT D-6 LGP dozer <br />except where haul routes were established. Haul route consisted of five-foot lifts to be spread <br />into 2-foot lifts later. Laborers were present at all times during placement holding the high <br />volume collection piping in place, removing debris/sandbags, and assisting the dozer operator <br />with lift thickness. All DCF was placed on previously approved primary geomembrane. AMEC <br />field representatives monitored the DCF placement constantly. <br />DCF was also placed over previously placed DCF constructing a 5-foot road to access the <br />south toe berm. This was performed using a CAT D-6 LGP dozer. <br />M Storm Water Management <br />A) Best Management Practices <br />Best Management Practices are being observed throughout the VLF Phase 5 Project. <br />IIl) Material Processing <br />A) Drain Cover Fill Process Area <br />Drain Cover Fill (DCF) was processed during the week. <br /> <br />Location This Week Cumulative <br />Comments <br /> (tons) (tons) <br />DCF Process 19,064 142,010 <br />Total 19,064 142,010 <br />IV) VLF Geosynthetics <br />A) Geomembrane Installation <br />1) VLF <br />Geomembrane installation within the Phase 5 VLF continued performing deployment, <br />seaming, and repair/QC activities. Geomembrane installation was performed in the area shown <br />on Figure 3. Approximately 237,803 square feet of primary 100mil LLDPE was deployed <br />using a 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 Lone Star representatives <br />prior to geomembrane deployment (see Figure 3). Approximately 11,964 linear feet of seam <br />was fusion welded using up to two fusion welding machines. Twenty-five destructive test <br />samples were marked during fusion seaming. All destructive tests performed were within <br />project specifications. Non-destructive testing was performed for fusion welded seams. Repairs <br />were performed using the extrusion welding method for all marked defects. Vacuum testing <br />was performed for all extrusion welded seams and repairs. <br />B) Anchor Trench <br />1) VLF <br />Anchor trench backfill was performed between stations C3+00 (+/-) and C7+50 (excluding the <br />low volume riser boots) and between stations G23+00 (+/-) and G30+00 (+/-) using a John <br />Deere 35D excavator and laborers. An AMEC representative observed and inspected the <br />VLF Weekly Report WE 09.25.10.D
