upslope of Bench J stations J10 +00 to J12 +00 where it was placed and compacted as structural
fill.
Subgrade:
No new subgrade was accepted during this reporting period. See the attached figure of accepted
subgrade in the Phase 1 area.
Soil Liner Fill (SLF):
SLF was hauled from the VLF stockpile below Bench F stations F0 +00 to F10 +00 to ADR haul
road station 15 +00 were it was placed on the slope above Bench B stations B10 +00 to B16 +00
and compacted per project specification.
The SLF surface was reconditioned from Bench B to Bench DD between approximate stations
134 +00 to B12 +00. Nuclear density and moisture testing was also conducted and the area was
accepted for liner placement.
See the attached Soil Liner Fill Map for accepted SLF in the Phase 1 area.
Cameron Site: SLF processing continued at the Cameron Site.

C) Geomembrane:
Phase 1 80 -mil DSMS LLDPE Liner Installation
Twenty -two rolls of 80 -mil DSMS geomembrane liner were deployed. Panels P11 through P54
were installed totaling 166,714 square feet with 8,011 lineal feet of welded seams.
Destructs DX -2 and DF -1 through DF -13 were marked, cut, and tested with passing results. DX-
3 and Destructs DF -14 through DF -20 were marked but not yet tested.
Approximately 462 lineal feet of anchor trench was excavated and 653 feet was backfilled over
the installed liner per project technical specifications.
D) Drain Cover Fill (DCF)
Ames' crusher operations continued with drain cover fill production.
Cat 740 trucks hauled drain cover fill to the PSSA. Haul roads for the Cat 740s were maintained
at least 4 feet above the secondary geomembrane and HVSCS piping.
Drain cover fill was placed on accepted primary liner in minimum 2 -foot lifts in the PSSA on
panels P19 to P20; P64 to P66; P76; P80 to P92; P122 to P130; P142 to P155; P157 to P162;
P193 to P195; P214 to P217; P219 to P221; P338 to P344; P347 to P353; P355 to P360; P362 to
