Earth & Environmental
C) Slope Contouring
1) VLF
Slope contouring was performed in the following areas: between stations E2+00 (±/-) and
E6+00 (+/-), approximately 0 to 200 feet right of centerline; between stations H0+00 (+/-) and
H20+00 (+/-), approximately 0 to 400 feet right of centerline; and between stations J24+00
(+/-) and J30+00 (+/-), approximately 150 feet left of centerline to 150 feet right of centerline.
Slope contouring was performed using various CAT dozers and various CAT excavators. The
material generated as the cut progressed was pushed down the slope.
D) Overburden to Stockpile
1) VLF
Oversize rock within the Phase 5 VLF fill area was removed from fill/cut areas and hauled to
the overburden stockpile area east of the east perimeter road near stations A29+00 (+/-) to
A32+00 (+/-) right of centerline.
E) Cut to Fill
1) VLF
A CAT 385 excavator was used to excavate structural fill material from between stations
E8+00 (+/-) and E22+00 (+/-), approximately 0 to 200 feet right of centerline and between
stations J4+00 (+/-) and J10+00 (+/-), approximately 100 to 150 feet left of centerline. The
structural fill material was loaded into CAT 777 haul trucks with assistance from various CAT
dozers.
Structural fill was between stations A54+00 (+/-) and A58+00 (+/-), approximately 0 to 100
left of centerline and between stations between stations C2+00 (+/-) and C7+50 (+/-),
approximately 30 feet left of centerline to 30 feet right of centerline. Structural fill was placed
in 18" to 24" lifts using various CAT dozes. 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
was applicable).
Blast pattern drilling was performed between stations E18+00 (+/-) and E19+50 (+/-),
approximately 40 to 60 feet right of centerline using one track mounted drill rig. Blasting was
performed in this area on, Monday 6/14/2010. This was the final blast for the Phase 5 VLF.
F) Soil Liner Fill
1) VLF
Soil liner fill (SLF) placement continued in the areas shown in Figure 3, hauling from the East
Cresson Clay borrow. Subgrade was approved and moisturized prior to placement using a
tandem-axel water truck. Placement was performed using two CAT D-6 dozers, and one CAT
skid steer loader in a one-foot compacted lift. Moisture conditioning was performed using a
tandem-axel water truck and compaction was performed using a 10-ton vibratory smooth drum
compactor. Nuclear density testing, moisture verification, and depth checks were performed in
the geomembrane deployment areas throughout the week. All test results were within project
specifications and all test locations were surveyed by Ames.
