ameley <br /> A Cat excavator was used to remove and regrade structural fill material washed down by rain at <br /> and above Bench A between stations A14+00 to A16+00. <br /> An excavator was observed in the Phase 2 diversion channel cutting in rough grade. <br /> Subgrade: <br /> A Cat dozer graded downslope of stations D10+00 to DDO+00 at the base of the Ball Mill fill !n the <br /> Phase 1 area while a Cat hammer hoe broke oversized rock within the subgrade. A Cat smooth <br /> drum roller compacted the finished subgrade. <br /> Cat dozers graded the subgrade near stations 18+00 to 110+00 above the former riprap <br /> processing area realigning the haul road. A Cat smooth drum roller was observed compacting in <br /> the area. <br /> No new subgrade was approved during this reporting period. See the attached figure of <br /> approved subgrade in the Phase 1 area. <br /> Soil Liner Fill: <br /> Cat dozers spread soil liner fill in the Phase 1 area between Bench DID and Bench B between <br /> approximate stations B2+00 to 66+00. A Cat 312 excavator formed the 9,550' bench between <br /> stations DD00+00 to DD01+00. <br /> A Cat excavator removed excess soil liner fill (SLF)washed down from rain near station B12-I-00. <br /> SLF Processing: <br /> Cameron Site: SLF processing resumed at the Cameron Site. <br /> Underdrain System: <br /> Primary Underdrain: Complete. <br /> Secondary Underdrain: No work was performed during this reporting period. <br /> Tertiary Underdrain: Complete within the PSSA footprint. <br /> B) Underground Workings: <br /> Underground working UG#6313 was blasted. Additional remediation is required. <br /> Workings UG#6117, UG#6153, UG#6551, and UG#6579 were prepared for a concrete plug. <br /> Additional remediation is required. <br /> C) Geomembrane: <br /> PSSA <br /> Primary 100-mil DSMS LLDPE Liner Installation <br /> ECA installed 100-mil LLDPE smooth geomembrane in the PSSA. Panels P-314 through P-372 <br /> were deployed on approved LVSCF. Twenty one(21)full rolls and multiple partial rolls of 100-mil <br /> LLDPE smooth geomembrane were deployed yielding 7,539 lineal feet of fusion welds for an <br /> approximate installed weekly total of 132,024 square feet. A wrinkle was removed from panels <br /> P-73 to P-76 by cutting out excess material and fusion welding the liner back together. Quality <br /> control was performed using two extrusion guns. All seams were fusion welded per project <br /> technical specifications. All work performed was observed by AMEC QA personnel. <br /> Approximately 383 lineal feet of anchor trench was backfilled over primary liner and compacted <br /> per project specifications. <br /> 2014 09 27-MLE2 WEEKLY FINAL Page 2 of 7 <br />
