,: <br />,; .. <br />' Phase IVb'Weekly Suinmary No. 33' "' Page 2 <br />`003-2203 <br />Ames hauled, placed, and compacted Channel Lining Fill (CLF) material into the Phase IVb permanent <br />diversion channel, south and west of Substation Hill. CLF material was worked, and compacted per <br />project plans. <br />Ames removed Drain Cover Fill (DCF) from the Phase Nb VLF northeastern limits in preparation for <br />geomembrane liner repairs. <br />Ames continued production of DCF at the screen plant located neaz the Secondary Crusher. Ames also <br />resumed limited production of SLF. <br />Ames completed placement of High Volume Solution Collection System (HVSCS) secondary and <br />tertiary piping within the Phase Nb OSA limits, followed by Drain Cover Fill (DCF) haul and <br />placement per project specifications. <br />Poly-Flex completed deployment of 80-mil single-sided textured LLDPE geomembrane in the Phase <br />Nb OSA on the east-facing slope of Chicken Hawk Hill. Poly-Flex deployed 80-mil single-sided <br />textured LLDPE geomembrane over an azea of approximately 156,916 squaze feet in the Phase Nb <br />OSA during this reporting period. Geomembrane panels B-949 through B-1002 were deployed, seamed, <br />and tested by Poly-Flex. Destructive fusion and extrusion seam samples DFb-273 through DFb-290 <br />and DXb-48 through DXb-54 were iuazked and removed. The results of testing on destructive fusion <br />and extrusion samples DFb-240 through DFb-242, DFb-244 through DFb-271, DFb-273 through DFb- <br />289, and DXb-48 through DXb-54 passed per project specification. DFb-243, DFb-272, and DFb-290 <br />failed to meet project specification and additional destmctive samples (DFb-243a1, DFb-24361, DFb- <br />272a1, DFb-27261, DFb-29061, and DFb-29062) were taken across approximately 270 linear feet of <br />fusion weld until passing conditions were met. The delineated failure across the seaming length was <br />capped and extrusion welded. <br />A map of the area worked during this reporting period is provided in Attachment C. <br />Phase Nc <br />Ames resumed contouring and compaction of subgrade Structural Fill (SF) in prepazation for Soil Liner <br />Fill (SLF) placement in the Phase Nc OSA scheduled for next construction season. <br />ADR Liner Expansion <br />Ames compacted SLF material into the ADR Liner Expansion area east of the CC&V lab. SLF <br />material was worked, tested, and passed per project specifications prior to SLF surface acceptance. <br />Ames completed excavation of the ADR Liner expansion geomembrane anchor trench on the east and <br />north side of the CC&V lab, excavating approximately 400 linear feet of anchor trench in preparation <br />for geomembrane placement. Ames also completed backfiil and compaction of approximately 400 <br />linear feet of ADR Liner expansion anchor trench. <br />Poly-Flex completed deployment of 100-mil single-sided textured and 100-mil smooth LLDPE <br />geomembrane in the ADR Liner Expansion area.
