amecIO <br />dozer. Each lift was moisture conditioned using a CAT 773 water truck (when necessary) and <br />compacted using a 10-ton vibratory smooth drum compactor, passing over the entire fill <br />surface at least 4 times (method compaction technique was applicable). <br />A CAT 988 loader was used to load structural fill between stations G26+00 (+/-) and G30+00 <br />(+/-), at centerline. The structural fill was loaded into CAT 740 articulating haul trucks and <br />placed between stations G27+00 to G29+50, approximately 100 to 200 feet left of centerline. <br />D) Soil Liner Fill <br />1) VLF <br />Soil liner fill (SLF) placement continued in the areas shown on Figure 2, hauling from the <br />temporary stockpile locations. Subgrade was approved and moisturized prior to placement <br />using a tandem-axel water truck. Placement was performed using a CAT D-6 LGP dozer, a <br />CAT D-7 LGP dozer and a CAT D-8 dozer in a one-foot compacted lift. Moisture conditioning <br />of SLF material was performed using a tandem-axel water truck and compaction was achieved <br />using a 10-ton vibratory smooth drum compactor. Nuclear density testing, moisture <br />verification, and depth checks were all performed, producing results within project <br />specifications. Moisture-density relations were obtained in accordance with AST D-698-07. <br />Test and sample locations were 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 5, advancing in front of the placement. Four-inch CPeP was placed and <br />sandbagged in accordance with design drawings, constructing the mainline and the tertiary <br />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 5. The LVSCF was hauled from the processing <br />area to the placement area using CAT 740 haul trucks loaded by a CAT 988 front-end loader. <br />The LVSCF was placed in a 3-foot lift using a CAT D-7 LGP dozer except where haul routes <br />were established. Haul route consisted of five-foot lifts, to be spread into 3-foot lifts later. <br />Laborers were present at all times during placement holding the low volume collection piping <br />in place, removing debris/sandbags, and assisting the dozer operator with lift thickness. All <br />LVSCF was placed on previously approved secondary geomembrane. AMEC field <br />representatives monitored the 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 />VLF Weekly Report WE 08.28.10.1)
