D) Overburden to Stockpile
1) VLF
Oversize rock within the Phase 5 VLF fill area was removed from fill areas and hauled to the
overburden stockpile area east of the east perimeter road near stations A28 +00 ( + / -) to A36 +00
( +/ -).
E) Cut to Fill
1) VLF
A CAT 385 excavator and a John Deere 850 excavator were used to excavate structural fill
material from the following areas: between stations E0 +00 ( + / -) and E1 +50 ( + / -),
approximately 10 to 50 feet left of centerline; between stations F3 +00 ( + / -) and F8 +50 ( + / -),
approximately 30 to 300 feet right of centerline; between stations H5 +00 ( + / -) and H12 +00
( + / -), approximately 0 to 100 feet left of centerline; and between stations K6 +00 ( + / -) and
K8 +00 ( + / -), approximately 75 to 125 feet right of centerline. The structural fill material was
loaded into CAT 777 haul trucks and hauled to fill areas.
Prior to structural fill placement existing fill areas were ripped and frost was allowed to thaw
or was removed. Existing fill temperature were monitored and found to be above 32 °F before
fill placement. An AMEC representative monitored ambient temperatures on an hourly basis
during fill placement. Fill temperatures were monitored during ambient temperatures below
32 °F and ranged between 33 ° F to 36 °F.
Structural fill was placed in the following areas: between stations A20 +00 ( + / -) and A26 +00
( + / -), approximately 25 to 200 feet left of centerline; between stations A54 +00 ( + / -) and
A57 +00 ( + / -), approximately 30 to 100 feet left of centerline; between stations C0 +50 ( + / -) and
C7 +75 ( + / -), approximately 75 feet left of centerline to 75 feet right of centerline; between
stations F7 +50 ( + / -) and F12 +50 ( + / -), approximately 150 feet left of centerline and 30 feet
right of centerline; between stations H32 +00 ( + / -) and H34 +00 ( + / -), approximately 10 to 100
feet left of centerline; and between stations J7 +00 ( + / -) and J10+00 ( + / -), approximately 40 to
150 feet left of centerline. Structural fill was placed in 18" to 24" lifts using various CAT
dozers. Each lift was moisture conditioned using a CAT 773 water truck (when necessary) and
compacted using a 10 -ton vibratory smooth drum compactor, passing over the entire fill
surface at least 4 times (method compaction technique is applicable). Ambient and fill
temperatures were monitored and recorded during fill placement.
Blast pattern drilling was performed between stations H2 +00 ( + / -) and H10 +00 ( + / -),
approximately 50 to150 feet left of centerline. Blasting was performed on Monday (4/5/2010),
Tuesday (4/6/2010), Wednesday (4/7/2010), and Thursday (4/8/2010). No blasting was
performed Friday (4/9/2010) or Saturday (4/10/2010).
F) Material Processing
1) East Cresson Clay Borrow Area
Processing of Soil Liner Fill material continued this week. A CAT D -8 dozer, a CAT 320
excavator, a CAT 966 front -end loader, and tandem -axel haul trucks were used to excavate, haul,
and process the material.
