amec'O <br />Earth & Environmental <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 />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 using the same equipment and procedures. All LVSCF was <br />placed on previously approved secondary geomembrane. AMEC field representatives observed <br />placement constantly during both day and night shifts. <br />1) 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 />Location This Week <br />(tons) Cumulative <br />(tons) Comments <br />E Cresson Clay Processing 10,243 155,621 <br />S Cresson Clay Processing 0 201,199 Processing in area complete. <br />Squaw Gulch Processing 0 35,816 Processing in area complete. <br />Total 10,243 388,025 <br />2) Low Volume Solution Collection Fill Material <br />Processing of LVSCF material is complete. <br />Location This Week Cumulative Comments <br /> (tons) (tons) <br />Dump 4 LVSCF Processing 0 405,067 Processing in area complete <br />,n Miscellaneous <br />No work was performed during the week. <br />VLF Weekly Report WE 06.26.10.D
