Earth & Environmental
High volume solution collection piping continued with the perforation of the 26 -inch HDPE
risers. An AMEC field representative observed the perforation and construction was
performed in accordance with design drawings and project specifications.
2) Drain Cover Fill (DCF)
DCF placement within the Phase 5 VLF began in the area show on Figure 6. The DCF was
hauled from the processing area to the placement area using CAT 740 haul trucks loaded by a
CAT 988 front -end loader. The DCF was placed in a 2 -foot lift using a CAT D -8 LGP dozer
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.
G) Material Processing
1) East Cresson Clay Borrow Area
Processing of SLF material continued this week. A CAT 320 excavator, a CAT 330 excavator,
a CAT 950 front -end loader, and tandem -axel haul trucks were used to excavate, haul, and
process the material.
2) Drain Cover Fill (DCF) Processing
Processing of DCF material continued this week using a CAT D -9 dozer.
III) Storm Water Management
A) Temporary Erosion Controls
Construction of silt fence and sumps was performed at the east slope of Phase 5 VLF. This was
performed to prevent and control erosion of the slope and will continue.
B) Best Management Practices
Best Management Practices are being observed throughout the Phase 5 VLF Project. Storm water
controls were maintained throughout the week. Precipitation was not substantial throughout the
week. Storm water controls are being observed in the East Cresson Clay Borrow.
