AWN& <br />ame <br />Earth & Environmental <br />High volume solution collection piping continued with the perforation of the 26-inch HDPE <br />risers. An AMEC field representative observed the perforation and construction was <br />performed in accordance with design drawings and project specifications. <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-8 LGP dozer <br />except where haul routes were established. Haul route consisted of five-foot lifts to be spread <br />into 2-foot lifts later. Laborers were present at all times during placement holding the high <br />volume collection piping in place, removing debris/sandbags, and assisting the dozer operator <br />with lift thickness. All DCF was placed on previously approved primary geomembrane. AMEC <br />field representatives monitored the DCF placement constantly. <br />G) 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 4,910 198,028 <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 4,910 430,432 <br />2) Drain Cover Fill (DCF) Processing <br />Processing of DCF material continued this week using a CAT D-9 dozer. <br /> <br />Location This Week Cumulative <br />Comments <br /> tons tons <br />DCF Process 14,518 21,518 <br />Total 14,518 21,518 <br />III) Storm Water Management <br />A) Temporary Erosion Controls <br />Construction of silt fence and sumps was performed at the east slope of Phase 5 VLF. This was <br />performed to prevent and control erosion of the slope and will continue. <br />B) Best Management Practices <br />Best Management Practices are being observed throughout the Phase 5 VLF Project. Storm water <br />controls were maintained throughout the week. Precipitation was not substantial throughout the <br />week. Storm water controls are being observed in the East Cresson Clay Borrow. <br />VLF Weekly Report WE 07.31.10.1)
