amecqO <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 haul trucks from the temporary stockpile locations. <br />Subgrade was approved and moisturized prior to placement using a tandem-axel water truck. <br />Placement was performed using various CAT dozers in a one-foot compacted lift. Moisture <br />conditioning of SLF material was performed using a tandem-axel water truck and compaction <br />was achieved using a 10-ton vibratory smooth drum compactor. Nuclear density testing, <br />moisture verification, and depth checks were all performed, with results within project <br />specifications. Test locations were surveyed by Ames. <br />E) 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 Figures 5a and 5b, advancing in front of the placement. CPeP was placed and sandbagged in <br />accordance with design drawings and project specifications. <br />2) Drain Cover Fill (DCF) <br />Drain cover fill (DCF) placement within the Phase 5 VLF continued. DCF was placed in the <br />area show on Figures 5a and 5b. The DCF was hauled from the processing area to the <br />placement area using CAT 740 haul trucks. The DCF was placed in a 2-foot lift using three <br />CAT D-6 LGP dozers, a CAT D-7 LGP dozer and a CAT D-8 LGP dozer except where haul <br />routes were established. Haul route consisted of five-foot lifts to be spread into 2-foot lifts <br />later. Laborers were present at all times during placement holding the high volume collection <br />piping in place, removing debris/sandbags, and assisting the dozer operator with lift thickness. <br />All DCF was placed on previously approved primary geomembrane. AMEC field <br />representatives monitored the DCF placement constantly. <br />3) Ore Placement <br />Loading of the Phase 5 PSSA began using a CAT D-9 LGP dozer. The portion of the ramp <br />without underlying geomembrane was constructed using overburden from the mine pit. <br />Crushed ore was then placed beginning when the toe of the fill was close to the anchor trench. <br />Twenty feet of cover was then verified, by survey, prior to mine haul trucks crossing over the <br />geomembrane. The toes of the ramp were surveyed ensuring twenty feet of cover, in haul <br />areas, during placement. An AMEC field representative was present during ore placement. <br />Night shift for this operation began 10/19/2010. <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 10.23.10.13
