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 Figure 1. The DCF was hauled from the processing area to the placement area <br />using CAT 740 haul trucks. The DCF was placed in a 2-foot lift using various CAT dozers <br />except where haul routes were established. Haul routes 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 />VLF WeeklyReport WE 12.01.1OD
