ameO <br />E) Low Volume Solution Collection System <br />1) Low Volume Solution Collection Piping <br />No work performed during the week. <br />2) Low Volume Solution Collection Fill (LVSCF) <br />No work performed during the week (see Figure 5 for previous LVSCF placement). <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 />2) Drain Cover Fill (DCF) <br />DCF placement within the Phase 5 VLF began in the area show on Figure 6. The DCF was <br />hauled from the processing area to the placement area using CAT 740 haul trucks loaded by a <br />CAT 988 front-end loader. The DCF was placed in a 2-foot lift using a CAT D-6 LGP dozer, a <br />CAT D-7 LGP dozer and a CAT D-8 LGP dozer except where haul routes were established. <br />Haul routes consisted of five-foot lifts to be spread into 2-foot lifts later. Laborers were present <br />at all times during placement holding the high volume collection piping in place, removing <br />debris/sandbags, and assisting the dozer operator with lift thickness. DCF placement was also <br />performed during night shift using the same equipment and procedures. All DCF was placed <br />on previously approved primary geomembrane. AMEC field representatives monitored the <br />DCF placement constantly. Construction of the pipe corridor at the north toe berm began using <br />additional DCF to create a 15 foot bench. <br />G) Material Processing <br />1) East Cresson Clay Borrow Area <br />Clay processing is complete. <br /> <br />Location This Week <br />tons Cumulative <br />tons <br />Comments <br />E Cresson Clay Processing 0 198,028 Processing in area complete. <br />S Cresson Clay Process in 0 201,199 Processing in area complete. <br />Squaw Gulch Processing 0 35,816 Processing in area complete. <br />Total 0 430,432 <br />2) Drain Cover Fill (DCF) Processing <br />Processing of DCF material continued this week using a CAT D-9 dozer. <br />Location This Week Cumulative Comments <br /> (tons) (tons) <br />DCF Process 52,107 73,625 <br />Total 52,107 73,625 <br />VLF Weekly Report WE 08.07.10.D.docx
