Phase 1 80 -mil DSMS LLDPE Liner Installation
No new liner was deployed this week.
D) Drain Cover Fill (DCF)
Ames crusher operations continued 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 P116 to P123; P154 to P156; P288 to P294; P331 to P353; 355 to P370; P372; P385 to
P396; P398 to P405; and P403 to P426.
Drain cover fill was placed around the HVSCF risers and manifold with a Cat 330 track hoe after
the Primary geomembrane was approved for DCF placement on the PSSA sump area.
See the attached DCF map for all placement
E) High Volume Solution Collection System Piping (HVSCS):
Four, 12, and 24 -inch ADS HVSCS piping was laid out on the on the PSSA inboard slopes.
Fusion welding occurred on the HVSCS HDPE 28 -inch piping in the PSSA floor.
The HVSCS vertical riser bases were cleaned and realigned to plan position.
All four sections of HVSCS vertical louvered screen and compression sections on the vertical
riser base plate were installed in the PSSA sump as well as a section of 28 -inch HDPE pipe from
the manifold on the PSSA floor.
II) Storm Water Management
Best Management Practices (BMPs) are being performed.
CQA ACTIVITIES:
1) Field Activities: Field activities and observation during this reporting period included: Slope grading
and fill placement; nuclear density and moisture testing; HVSCS pipe cleaning; HVSCS HDPE piping
fusion; HVSCS vertical louvered and compression section installation; ADS HVSCS piping layout-,
and DCF sampling.
II) Laboratory Activities: Permeability, Atterberg limits, moisture, and sieve analysis laboratory testing
continued.
The following samples were collected and returned to AMEC's laboratory for analysis:
Drain Cover Fill sample DCF 114 (Control sample)
Drain Cover Fill sample DCF 12 -R (Record sample)
Structural Fill sample SF 98 -R (Record sample)
Soil Liner Fill sample SLF -156C (Control sample from the Cameron Site)
