A Cat 330 excavator and a D6 GPG dozer trenched for the Low Volume Solution Collection (LVSC) riser piping in
the southeast comer of the PSSA between the closure drains and the 9450' elevation bench.
A Cat 330 excavator loaded material excavatE d from above underground working # 6273 into Cat 740 haul trucks.
The material was placed as structural fill using a Cat dozer between the %:1 slope and ADR platform. The fill was
compacted by a Cat CS56 smooth drum roller The structural fill was placed and compacted per project
specification. Fine materials were used to fini h slope grades at the 9450 elevation near the ADR Platform.
A Cat CS56 smooth drum roller compacted the subgrade between stations FF+00 to FF2+00 and DD2+00 to
DD7+00 as well as downslope of stations B10 0 to B12+00.

A Cat dozer graded material upslope at statio J1+00 to J2+00 creating an access ramp to the ADR haul road fill
area. The haul road access ramp is for future Soil Liner Fill haulage from the Cameron.
Note: An AMEC field professional monitored structural fill material temperatures placed within fill areas. Average
structural fill temperatures were above 32 °F.
