�1 <br />Alh <br />CS56 smooth drum roller. The structural fill was placed and compacted per project specification. A few select loads <br />were transported to the rip rap prescreen stockpile. <br />Cat dozers pushed material downslope from Dump 4 above the ADR Haul Road fill area near stations 70+00 to <br />75+00. Excess material was placed as structural fill near station K34+OD. The structural fill was placed and <br />compacted per project specification. <br />A Cat D6 GPG dozer regarded the trench for the Low Volume Solution Collection (LVSC) riser piping in the <br />southeast corner of the PSSA between the closure drains and the 9450` elevation bench. <br />A Cat GPS D6 placed cut to fill downslope of station D11+00. Structural fill was placed in 3 foot minus lifts and <br />compacted using a Cat CS56B smooth drum roller per project specification. <br />i <br />Cat dozers cut the slopes to rough grade downslope of stations FF6+00 to FF8 +00, B4+00 to B8+00, CO+00 to <br />C5+00, and A21+00. <br />Cat 330 excavators with rock hammers and buckets broke apart and cut the slopes to rough grade near stations <br />A+00 to A2+00, upslope of stations DD10 +00 to DD12 +00, and downslope of stations C2 +00, FF6+00 to FF8 +00, <br />and B4+00 to B8+00. <br />A Cat dozer graded material upslope at stations J1+00 to J2+00 creating an access ramp to the ADR haul road fill <br />area. The haul road access ramp is for future Soil Liner Fill (SLF) haulage from the Cameron. <br />Note: An AMEC field professional monitored structural fill material temperatures placed within fill areas. Average <br />structural fill temperatures were above 32 °F and snow was removed prior to fill placement. <br />Clay fSLF) Processing: <br />Cameron Site: No clay mining or processing occurred at the Cameron Site. Approximately 244,860 tons of clay I <br />soil liner fill (SLF) material have been produced at the Cameron site. SLF produced from the operation remains <br />stockpiled at Cameron Site for future use. <br />Squaw Gulch Clay Borrow Site: Clay mining and processing did not occurr at the Squaw Gulch Clay Borrow Site <br />due to wet conditions. Approximately, 125,409 tons of soil liner fill material has been produced at the Squaw Gulch <br />Clay Borrow Site to date. <br />Underdrain System: <br />Primary Underdrain: No work occurred on the primary underdrain. <br />Secondary Underdrain: Excavators worked en trenching in the PSSA for secondary underdrain below station <br />A14 +50. <br />Tertiary Underdrain: No work occurred on Me tertiary underdrain. <br />Tree Grubbing and Clearing, Chipping: <br />Clearing and grubbing occurred in the Phase 2 channel alignment east of the Phase 2 pond. <br />B) Underground Workings <br />• Confirmatory Drilling <br />Fourteen (14) geophysical confirmation index oints were drilled within the PSSA floor to investigate anomalies in <br />geophysical findings. No voids were found, drill holes were grouted. <br />i <br />Confirmation drilling occurred at underground working #6280. The working was partially remediated previously. <br />Additional remediation is required. <br />Page 2 of 7 MLE2 WE 10 May 2014.doc <br />
