Geotextile <br />was placed over any geomembrane within three feet of the slope toe. A 10 -ton smooth drum <br />roller was used to compact the surface of the ore slope 2' or more above the geomembrane and <br />a plate compactor was used to compact the remaining portion of the slope. <br />H) Low Volume Solution Collection System <br />1) Low Volume Solution Collection Piping <br />Placement of the low volume solution collection system continued at the LVSCF placement <br />area shown in Figure 6, 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 />The trench for the low volume solution collection riser pipe was excavated using a CAT 345 <br />excavator. <br />2) Low Volume Solution Collection Fill (LVSCF) <br />Low volume solution collection fill (LVSCF) material placement within the Phase 5 VLF <br />continued. LVSCF was placed in the area show in Figure 6. The LVSCF was hauled from the <br />processing area to the placement area using CAT 740 haul trucks loaded by a 988 front -end <br />loader. The LVSCF was placed in a 3 -foot lift using two CAT D -6 LGP dozers, a CAT D -7 <br />LGP dozer, and a CAT D -8 LGP dozer, expect were haul routes were established. Haul route <br />consisted in five -foot lifts, to be spread into 3 -foot lifts later. Laborers were present at all times <br />during placement holding the low volume solution collection piping in place, removing <br />debris /sandbags, and assisting the dozer operator with lift thickness. LVSCF placement was <br />also performed during night shift (6/29/2010 only) using the same equipment and procedures. <br />All LVSCF was placed on previously approved secondary geomembrane. AMEC field <br />representatives observed placement constantly during both day and night shifts. <br />I) Material Processing <br />1) East Cresson Clay Borrow Area <br />Processing of SLF material continued this week. A CAT 320 excavator, a CAT 330 excavator, <br />a CAT 950 front -end loader, and tandem -axel haul trucks were used to excavate, haul, and <br />process the material. <br />J) Miscellaneous <br />No work was performed during the week. <br />VLF Weekly Report WE 07.03.10.D <br />
