ameO <br />smooth drum compactor, passing over the entire fill surface at least 4 times (method <br />compaction technique was applicable). <br />D) Soil Liner Fill <br />1) VLF <br />Soil liner fill (SLF) placement continued in the areas shown on Figure 2. One CAT 385 <br />excavator loaded 40 ton articulating and CAT 777 haul trucks from the temporary stockpile <br />locations. Subgrade was approved and moisturized prior to placement using a tandem-axel <br />water truck. Placement was performed using a CAT D-6 LGP dozer, two CAT D-8 dozer, and <br />a CAT skid steer loader in a one-foot compacted lift. Moisture conditioning of SLF material <br />was performed using a tandem-axel water truck and compaction was achieved using a 10-ton <br />vibratory smooth drum compactor. Nuclear density testing, moisture verification, and depth <br />checks were all performed, producing results within project specifications. Test locations were <br />surveyed by Ames. <br />E) Low Volume Solution Collection System <br />1) Low Volume Solution Collection Piping <br />Placement of the low volume solution collection system continued at the LVCSF placement <br />area shown on Figure 5a and 5b, advancing in front of the placement. Four-inch CPeP was <br />placed and sandbagged in accordance with design drawings, constructing the mainline and the <br />tertiary lines. The secondary geomembrane in the area was accepted prior to pipe placement. <br />2) Low Volume Solution Collection Fill (LVSCF) <br />Low volume solution collection fill (LVSCF) placement within the Phase 5 VLF continued. <br />LVSCF was placed in the area show on Figure 5a and 5b. The LVSCF was hauled from the <br />processing area to the placement area using CAT 740 haul trucks loaded by a CAT 988 front- <br />end loader. The LVSCF was placed in a 3-foot lift using a CAT D-6 LGP dozer, a CAT D-7 <br />LGP dozer, and a CAT D-8 LGP dozer except where haul routes were established. Haul route <br />consisted of five-foot lifts, to be spread into 3-foot lifts later. Laborers were present at all times <br />during placement holding the low volume collection piping in place, removing <br />debris/sandbags, and assisting the dozer operator with lift thickness. All LVSCF was placed on <br />previously approved secondary geomembrane. AMEC field representatives monitored the <br />LVSCF placement constantly. <br />F) High Volume Solution Collection System <br />1) High Volume Solution Collection Piping <br />No placement performed during the week. <br />2) Drain Cover Fill (DCF) <br />No placement performed during the week (see Figure 6 for previous DCF placement). <br />II) Storm Water Management <br />A) Best Management Practices <br />Best Management Practices are being observed throughout the VLF Phase 5 Project. <br />VLF Weekly Report WE 09.04.10.13
