amecl* <br />compactor, passing over the entire fill surface at least 4 times (method compaction technique <br />was applicable). <br />D) Soil Liner Fill <br />1) VLF <br />No SLF placement was performed during the shift. (see Figure 2 for previously placed soil <br />liner fill). <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. CPeP was placed and sandbagged <br />in accordance with design drawings, constructing the mainline and the tertiary lines. The <br />secondary geomembrane in the area was accepted prior to pipe placement. The low volume <br />solution collection system installation is complete. <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 three CAT D-6 LGP dozers, a CAT D-7 LGP <br />dozer and a CAT D-8 LGP dozer except where haul routes were established. Haul routes <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 />Placement of the high volume collection system continued at the DCF placement area shown <br />on Figure 6, advancing in front of the placement. CPeP was placed and sandbagged in <br />accordance with design drawings and project specifications. The primary geomembrane in the <br />area was accepted prior to pipe placement. <br />Installation of the high volume solution collection riser bases was performed using a Komatsu <br />300 excavator for placement. Prior to placement, approved geosynthetic clay liner (GCL) was <br />placed above the accepted primary geomembrane. Approved 3-inch closed cell foam and <br />conveyor belting were then placed above the GCL. Each riser base was placed individually <br />with 20-inch HDPE pipes installed between the rises. Each riser was surveyed prior to placing <br />the subsequent riser and center points were surveyed after placement was complete. AMEC <br />representatives observed the installation. The risers were found to be constructed in accordance <br />with the design drawings and project specifications. <br />VLF Weekly Report WE 09.25.10.1)
