Location This Week (tons) Cumulative (tons) Comments DCF Process 14,095 148,364 Total 14,095 148,364 D) Soil Liner Fill 1) VLF Soil liner fill (SLF) placement continued in the areas shown on Figure 2. Subgrade was approved and moisturized prior to placement using a tandem -axle water truck. The SLF material was moisture conditioned at the temporary stockpile and loaded into 40 -ton articulating haul trucks using a John Deere 744 front -end loader. Placement was performed using one CAT D -8 dozer, building an access road to planned SLF placement areas. This SLF will be reworked prior to geomembrane deployment in the area. Placement of the remaining SLF was performed using various CAT dozers and one skid steer loader in a one -foot compacted lift. Moisture conditioning of SLF material was performed in place using a tandem axle water truck and compaction was achieved using a 10 -ton vibratory smooth drum compactor. Nuclear density testing, moisture verification, and depth check testing was performed with results within project specifications. Test locations were surveyed by Ames. E) High Volume Solution Collection System 1) High Volume Solution Collection Piping Placement of the high volume collection system continued at the DCF placement area shown on Figure 5, advancing in front of the placement. CPeP was placed and sandbagged in accordance with design drawings and project specifications. 2) Drain Cover Fill (DCF) Drain cover fill (DCF) placement within the Phase 5 VLF continued. DCF was placed in the areas shown on Figure 5. The DCF was hauled from the processing area to the placement area using 40 -ton articulating haul trucks. The DCF was placed in a 2 -foot lift using various CAT dozers except where haul routes were established. Haul route consisted of five -foot lifts to be spread into 2 -foot lifts later. Laborers were present at all times during placement holding the high volume collection piping in place, removing debris /sandbags, and assisting the dozer operator with lift thickness. All DCF was placed on previously approved primary geomembrane. AMEC field representatives monitored the DCF placement constantly. F) Leak Detection Trench 1) VLF No work performed during the week. ame II) Storm Water Management A) Best Management Practices Best Management Practices are being observed throughout the Phase 5 VLF Project. III) Material Processing A) Drain Cover Fill Process Area Processing of Drain Cover Fill (DCF) continued at the DCF process area using a dozer. VLF Weekly Report WE 07.02.2011
