amec - <br /> A Cat excavator trenched the Phase 2 diversion ditch near station 16+00. The material was <br /> loaded into Cat 740 haul trucks and transported east of the Phase 2 where it was stockpiled for <br /> later use as structural fill. <br /> A Cat loader moved material from Bench B to the inboard Phase 1 embankment above the 9,450' <br /> elevation bench on the south side of the PSSA and placed it as structural fill. <br /> Cat dozers were finish grading and a Cat smooth drum roller compacted subgrade in various <br /> areas within PSSA and surrounding Phase 1 slopes. <br /> The Soil liner fill (SLF) surface was scarified downslope from stations Al2+00 to A18+00 and on <br /> the PSSA floor to allow for drying and reconditioning. <br /> SLF was transported from the Squaw Gulch SLF stockpile to the stockpile area above station <br /> DD5+00 in Phase 1 Area 1. SLF was also hauled and placed in the PSSA below stations <br /> A15+00 to A22+00. <br /> Subgrade: <br /> The following subgrade areas in the PSSA were compacted per project technical specifications to <br /> finished grade, inspected, and certified for SLF placement: <br /> From approximate stations A18+00 to A22+00 to the PSSA floor <br /> ➢ From approximate ADR road stations 7+00 to 12+00 to the PSSA floor <br /> From approximate ADR road stations 7+00 to 12+00 to Bench B <br /> See the attached subgrade acceptance map for all accepted subgrade locations. <br /> Soil Liner Fill: <br /> The following SLF areas in the PSSA were compacted per project specifications to finished <br /> grade, inspected, and certified for geomembrane placement: <br /> ➢ Due to wet weather no new SLF was approved for geomembrane placement during the <br /> week. SLF area below Al2+00 to A18+00 was re-approved for secondary liner <br /> deployment. <br /> See the attached SLF acceptance map for all accepted locations. <br /> SLF Processing: <br /> Cameron Site: No SLF mining or processing occurred at the Cameron Site. Approximately <br /> 244,860 tons of SLF material has been produced and remains stockpiled at the Cameron Site for <br /> future use. The processing equipment remains at the Cameron site. No new processing was <br /> performed during this reporting period. <br /> Underdrain System: <br /> Primary Underdrain: Complete. <br /> Secondary Underdrain: <br /> Approximately 175 feet of secondary underdrain trench was excavated, lined with geofabric, filled <br /> with underdrain fill, and covered with select structural fill from approximate ADR haul road station <br /> 15+00 upslope to the existing underdrain below the Ball Mill fill. Both ends of the secondary <br /> underdrain were tied into existing underdrain. <br /> Tertiary Underdrain: Complete within the PSSA footprint. <br /> B) Underground Workings <br /> 2014.08.09-MLE2 WEEKLY FINAL.DOCX Page 2 of 7 <br />
