Subgrade:
All subgrade areas in the PSSA footprint have been certified for soil liner fill (SLF) placement per
project technical specifications.
Two dozers were slope grading subgrade downslope of the south perimeter road stations P4+00
to P8+00 in the Phase 1 area.
Soil Liner Fill:
The following soil liner fill (SLF) areas in the PSSA were compacted per project technical
specifications to finished grade, inspected, and certified for geomembrane placement:
Between approximate stations A18+00 to A22+00 and the PSSA floor adjoining
previously approved SLF. This completes SLF surfaces approvals within the PSSA
footprint.
See the attached SLF acceptance map for all accepted locations.
Excess SLF was cut and regraded in the northeast corner of the PSSA below station A21+00.
The excess SLF was hauled to the stockpile above station DD5+00.
Cat 777 haul trucks transported soil liner fill from the stockpile near Dump 4 and from the
Cameron processing location to an area below stations FO+00 to F10+00 where it was stockpiled
for future use for Phase 1.
Low Volume Solution Collection Fill:
The following Low Volume Solution Collection Fill (LVSCF) areas in the PSSA were placed to
finished grade per project specifications, inspected, and certified for primary geomembrane
placement:
r The western half of the PSSA southern embankment.
See the attached LVSCF map for all placement and accepted locations for primary geomembrane
deployment.
SLF Processing:
Cameron Site: No SLF mining or processing occurred at the Cameron Site. However, Ames
began transporting the Cameron stockpiled SLF to a new stockpile located below stations FO+00
to F10+00 in the Phase 1 area. The processing equipment remains at the Cameron site. No new
processing was performed during this reporting period.
Underdrain System:
Primary Underdrain: Complete.
Secondary Underdrain: No work was performed during this reporting period.
Tertiary Underdrain: Complete within the PSSA footprint.
B) Underground Workings
Underground workings UG#6639, UG#6640, and UG#6461 were blasted in conjunction wiih
production cut blasting. Additional remediation is required.
Confirmatory drilling occurred at underground workings UG #6461 and UG#6639. Additional
