amec. , <br /> downslope of Bench M stations M34+00 to M42+00 in Phase 2. A Cat 330C excavator with a <br /> hammer attachment broke up oversized rock. <br /> Material hauled from the Surge area was placed and compacted as structural fill per project <br /> technical specifications between stations L4+00 to L12+00 on Bench L in Phase 1. A Cat 330C <br /> excavator with a hammer attachment broke up oversized rock. <br /> Slope grading occurred in Phase 1 by Cat dozers below stations F18+00, J2+00, and L4+50. <br /> Subgrade: Phase 1 rough subgrade prep occurred and base topography of Phase 2 areas <br /> occurred during this reporting period after clearing and grubbing was completed. <br /> Soil Liner Fill(SLF): (Placement Operations Temporarily Suspended) <br /> SLF was hauled from the Cameron Clay Pit area and stockpiled below Bench F between stations <br /> F0+00 and F10+00. <br /> Cameron Site: SLF processing continued at the Cameron Site during the first part of the week <br /> but was temporarily halted for processing equipment repair during the later part of the week. <br /> Underdrain System: <br /> Primary Underdrain: Complete. <br /> Secondary Underdrain: No work was performed during this reporting period. <br /> Tertiary Underdrain: No work was performed during this reporting period. <br /> Leak Detection: No work was performed during this reporting period. <br /> B) Underground Workings: <br /> Workings#6503,#6504, #6601.#6602,#6603, #6609,#6610; #6615, #6642, #6643; #6644, <br /> #6645,#6646,#6647,#6648, #6649, #6650, and#6651 were excavated to competent rock; <br /> backfilled per project specifications, and are considered rernediated. <br /> A Cat D6 dozer removed tailings from Working#6614 to provide access. The working was <br /> excavated 25 feet but the bottom of the shaft was not encountered. Confirmatory drilling <br /> occurred. Further remediation is required. <br /> Access was provided to Working#6010. The shaft was filled with 253 cubic yards of coarse shaft <br /> backfill to provide stability for confirmatory drilling_ Portions of the open adit between collapsed <br /> areas of the working were excavated per AMEC's remediation directive. Confirmatory drilling <br /> occurred. Additional drilling and remediation is required. <br /> Dozers removed shot rock from the Anaconda Mine Complex in preparation for geogrid <br /> placement. <br /> C) Geomembrane: <br /> Phase 1 80-mil DSMS LLDPE Liner Installation: (Installation is suspended at this time.) <br /> D) Drain Cover Fill(DCF) (Placement operations suspended at this time.) <br /> E) High Volume Solution Collection System Piping(HVSCS): <br /> No work was performed during this reporting period. <br /> 2014-12-20-mle2 weekly final Page 2 of 6 <br />
