A John Deere 870 excavator and Cat 740 haul trucks were used to cut the Phase 2 Diversion Channel from stations <br />17+00 through 19 +00. Material was hauled to and placed as structural fill at the toe of Dump 4 near station 136+00. <br />A Cat D8 dozer and a Cat CS56 smooth drum roller were used at the placement area. The fill was placed and <br />compacted per project specifications. <br />A smooth drum roller compacted the finished subgrade upslope from stations DD8+00 to DD12 +00. <br />Cat dozers cut the slope to rough grade downslope of stations G0 +00 to G2 +00, B0+00 to B14+00, E0+00 to <br />E6+00, C0+00 to C4+00, and DD6+00 to DD14 +00. <br />A Cat 345 excavator worked on shaping and grading the access road near station Q4+00. <br />A Cat 330 excavator was used to out the slope to grade at station P4+00 through P8+00 above the perimeter road. <br />A Cat 330 hammer hoe worked upslope from stations B10+00 through B11+00 to break up rock below the finish <br />grade. <br />Cat dozers were used to cut the slope and place as structural fill at ADR haul road stations 58+00 to 74+00 from <br />elevations 9,800 feet through 9,850 feet. The cut material was placed as structural fill and compacted using a Cat <br />CS56B smooth drum roller per project specification. <br />Note: An AMEC field professional monitored structural fill material temperatures placed within fill areas. Average <br />structural fill temperatures were above 32 °F. <br />Clay (SLF) Processing: <br />Cameron Site: No clay mining or processing occurred at the Cameron Site. Approximately 244,860 tons of clay / <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 occurred at the Squaw Gulch Clay Borrow Site. <br />Approximately, 114,000 tons of soil liner fill material has been produced at the Squaw Gulch Clay Borrow Site to <br />date. <br />Underdrain System: <br />Primary Underdrain: No work occurred on the primary underdrain. <br />Secondary Underdrain: No work occurred on the secondary underdrain. <br />Tertiary Underdrain: Approximately 150 lineal feet of tertiary underdrain was installed at the southern end of the <br />PSSA floor and was tied into the primary underdrain. <br />Tree /Slash Grubbing and Clearing Chipping• <br />No clearing or grubbing occurred. <br />B) Underground Workings <br />• Confirmatory Drilling <br />Confirmatory drilling occurred at underground working #6112 and UG #6119. Further remediation efforts are <br />required. <br />• Remediation <br />Underground working #U6112 was blasted, shot rock was removed, and was quantified for backfilling. Additional <br />remediation efforts are required. <br />Page 2 of 6 MLE2 WE 26 April 2014.doc <br />
