The DCF was placed in a 2 -foot lift using a two <br />CAT D -6 LGP dozers and a CAT D -8 dozer except where haul routes were established. Haul <br />route consisted of five -foot lifts to be spread into 2 -foot lifts later. Laborers were present at all <br />times during placement holding the high volume collection piping in place, removing <br />debris /sandbags, and assisting the dozer operator with lift thickness. All DCF was placed on <br />previously approved primary geomembrane. AMEC field representatives monitored the DCF <br />placement constantly. <br />Backfilling of the high volume solution collection risers and manifold was performed using a <br />CAT D -6 LGP dozer and a Komatsu 300 excavator. DCF material was pushed to the Komatsu <br />300 excavator and cast onto the risers. This was performed to allow for the continued <br />construction of the risers. <br />3) Ore Placement <br />Ore placement near the high volume solution collection continued using a CAT D -8 dozer. The <br />ore was hauled from the leading edge of the Phase IV heap placement using 40 -ton articulating <br />haul trucks loaded by a CAT 385 excavator. <br />II) Storm Water Management <br />A) Best Management Practices <br />Best Management Practices are being observed throughout the VLF Phase 5 Project. <br />III) Material Processing <br />A) Drain Cover Fill Process Area <br />Drain Cover Fill (DCF) was processed during the week. <br />ame$ <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 Figures 3a and 3b. Approximately 144,946 square feet of primary 80mil LLDPE and <br />primary 100mil LLDPE was deployed using a John Deere 200 excavator and a John Deere 544 <br />front -end loader with spreader -bar attachments. Subgrade was inspected and approved by <br />AMEC and Lone Star representatives prior to geomembrane deployment (see Figures 3a and <br />3b). Approximately 8,752 linear feet of seam was fusion welded using to two fusion welding <br />machines. Nineteen destructive test samples were marked during fusion seaming. All <br />destructive tests performed were within project specifications. Non - destructive testing was <br />performed for fusion welded seams. Repairs were performed using the extrusion welding <br />VLF Weekly Report WE 10.09.10.D <br />
