centerline; and between stations J7 +00 ( + / -) and J12 +00 ( + / -), approximately 0 to 100 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
No work performed during the week.
E) Cut to Fill
1) VLF
A CAT 385 excavator was used to excavate structural fill material between stations E9 +50
( + / -) and E 13 +00 ( + / -), approximately 20 feet left of centerline to 50 feet right of centerline
and J4 +00 ( + / -) and J10 +00 ( + / -), approximately 20 feet left of centerline to 20 feet right of
centerline. The structural fill material was loaded into CAT 777 haul trucks and hauled to fill
areas.
Structural fill was placed between stations A60 +00 ( + / -) and A64 +25 ( + / -), approximately 50
feet left of centerline to 20 feet right of centerline and between stations C0 +00 ( + / -) and C7 +00
( + / -), approximately 60 feet left of centerline to 60 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
was applicable).
Blast pattern drilling was performed between stations E7 +00 ( + / -) and E11 +00 ( + / -),
approximately 0 to 75 feet right of centerline. Blasting was performed on Monday (5/24/2010)
and Tuesday (5/25/2010). Blasting was not performed Wednesday (5/26/2010), Thursday
(5/27/2010), Friday (5/28/2010), and Saturday (5/22/2010).
F) Soil Liner Fill
1) VLF
Moisture conditioning of in -place SLF continued between stations B3 +00 ( + / -) and B10 +00
( + / -), approximately 0 to 600 feet right of centerline. A CAT D -6 dozer with a disc attachment
and a tandem -axle water truck were used to process the SLF, raising the moisture content.
Compaction of the SLF 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.
G) PSSA Ore Slope Construction
Construction of the remaining portion of the PSSA ore slope continued between stations G4 +00
( + / -) and G10 +00 ( + / -), approximately 0 to 225 feet left of centerline using a CAT D -6 LGP dozer
and a CAT 279 skid steer loader. Existing ore was pushed over the previously certified secondary
geomembrane, constructing the toe of the slope. Geotextile was placed over the geomembrane
within three feet of the slope toe. An AMEC field representative observed slope construction
constantly. A 10 -ton smooth drum roller was used to compact the surface of the ore slope 2' or
