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 F5 +00 ( + / -) and F7 +50 ( + / -),
approximately 50 to 100 feet right of centerline; between stations H4 +00 ( + / -) and H10 +50
( + / -), approximately 20 to 100 feet left of centerline; between stations; H24 +00 ( + / -) and
H26 +00 ( + / -), approximately 75 to 100 feet right of centerline; and between stations K11 +00
( + / -) and K13 +00 ( + / -), approximately 20 to 100 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 39 ° F.
Structural fill was placed in the following areas: between stations C0 +50 ( + / -) and C3 +00 ( + / -),
approximately 75 feet left of centerline to 75 feet right of centerline; between stations F7 +50
( + / -) and F12 +50 ( + / -), approximately 120 feet left of centerline to 30 feet right of centerline;
and between stations J8 +00 ( + / -) and J14 +00 ( + / -), approximately 50 to 200 feet right 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 H4 +00 ( + / -) and 1110 +00 ( + / -),
approximately 20 to 90 feet left of centerline. Blasting was performed on Monday (3/29/2010),
Tuesday (3/30/2010) and Friday (4/2/2010). No blasting was performed Wednesday
(3/31/2010), Thursday (4/1/2010) and Saturday (4/3/2010).
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. The processing plant went down Tuesday (3/16/2010) due to mechanical
problems.
