r ~ Phase IW Weekly Summary No. 16 Page 2 003-2203
Ames completed Drain Cover Fill (DCF) removal near the Phase III /Phase IVb PSSA tie-in in
preparation for east end berm and Phase IVb Ore Storage Area (OSA) construction. Ames resumed
DCF removal at the Phase I / IVa / IVb tie-in areas.
Ames began production of DCF at the screen plant located neaz the secondary crusher.
Ames. hauled and placed DCF onto the Phase IVb PSSA upper and lower geomembrane areas in
preparation for the east end berm construction.
Ames placed the Low Volume Solution Collection System (LVSCS) 14-inch riser piping in the 2H:1V
riser slope trench. Ames placed and graded existing Low Volume Solution Collection Fill (LVSCF)
onto the riser slope around the piping system, per project specifications.
Ames excavated and constructed approximately 300 feet of Primary Underdrain on the south slope of
Substation Hill in the Phase IVb area, including atie-in of the existing Secondary Underdrain on the
south slope.
Ames hauled and placed Bedding Fill (BF) material onto the east ore slope in the Phase IVb PSSA area,
neaz the east end berm construction area.
Poly-Flex continued deployment of 100-mil double-sided smooth (upper) LLDPE geomembrane in the
Phase Nb PSSA. Poly-Flex deployed 100-mil smooth LLDPE geomembrane over an area of
approximately 37,175 squaze feet in the Phase IVb PSSA during this reporting period. Geomembrane
panels U-253 through U-271 were deployed, seamed, and pressure tested by Poly-Flex. Destructive
fusion seam samples DFu-76 through DFu-81 and extrusion seam samples DXu-03 and DXu-04 were
marked and removed. Destructive fusion and extrusion seam peel and shear tests of samples DFu-69
through DFu-79 and DXu-03 and DXu-04 were performed and passed per project specifications.
Poly-Flex resumed deployment of 100-mil single-sided textured (lower) LLDPE geomembrane in the
Phase IVb PSSA. Poly-flex deployed 100-mil single-sided textured LLDPE geomembrane over an azea
of approximately 39,578 square feet in the Phase IVb PSSA during this reporting period.
Geomembrane panels L-586 through L-602 were deployed, seamed, and pressure tested by Poly-Flex.
Destructive fusion seam samples DF-153 through DF-163 and extrusion seam samples DX-26 and DX-
27 were marked and removed. Destructive fusion and extrusion seam peel and shear tests of samples
DF-153 through DF-163 and DX-26 and DX-27 were performed and passed per project specifications.
Poly-Flex resumed deployment of 100-mil double-sided smoot't (lower) LLDPE geomembrane in the
Phase IVb PSSA. Poly-flex deployed 100-mil smooth LLDPE geomembrane over an area of
approximately 42,430 square feet in the Phase IVb PSSA during this reporting period. Geomembrane
panels M-616 through M-636 were deployed, seamed, and pressure tested by Poly-Flex. Destructive
fusion seam samples DF-169 through DF-171 and extrusion seam samples DX-30 and DX 31 were
marked and removed. Destructive fusion and extrusion seam peel and shear tests of samples DF-169
through DF-171 and DX-30 through DX-31 were performed and passed per project specifications.
Poly-Flex resumed deployment of 80-mil single-sided textured LLDPE geomembrane in the Phase IVb
OSA. Poly-flex deployed 80-mil single-sided textured LLDPE geomembrane over an area of
