density testing, moisture verification, and depth check testing was performed with results
within project specifications. Test locations were surveyed by Ames.
D) High Volume Solution Collection System
1) High Volume Solution Collection Piping
Placement of the high volume collection system continued at the DCF placement area shown
on Figure 5A and Figure 5B, advancing in front of the placement. CPeP was placed and
sandbagged in accordance with design drawings and project specifications.
2) Drain Cover Fill (DCF)
Drain cover fill (DCF) placement within the Phase 5 VLF continued. DCF was placed in the
areas shown on Figure 5A and Figure 5B. The DCF was hauled from the processing area to the
placement area using 40 -ton articulating haul trucks. The DCF was placed in a 2 -foot lift using
various CAT dozers except where haul routes were established. Haul route consisted of five -
foot lifts to be spread into 2 -foot lifts later. Laborers were present at all times during placement
holding the high volume collection piping in place, removing debris /sandbags, and assisting
the dozer operator with lift thickness. All DCF was placed on previously approved primary
geomembrane. AMEC field representatives monitored the DCF placement constantly.
