amec <br /> A Cat D10 dozer cut the slope to rough grade downslope of stations F21+00 to F18+00. Excess <br /> material was placed as structural fill between stations F18+00 to F14+00. A Cat CS56 smooth <br /> drum roller was used to compact the placed fill. The structural fill was placed and compacted per <br /> project specifications. <br /> A Cat 330 excavator loaded tandem trucks with stockpiled material at the floor of the PSSA below <br /> stations A2+00 to A5+00. The material was hauled to the northern half of the PSSA floor and <br /> placed as structural fill. The structural fill was placed and compacted per project specifications. <br /> The southern half of the PSSA floor was compacted to finished grade and a subgrade inspection <br /> was performed followed by its acceptance. See the attached subgrade acceptance map for <br /> further location details. <br /> Cat dozers performed cut to fill the Ball Mill site access road crossing at the eastern Phase 2 <br /> boundary at the top of the ADR haul road. The structural fill was placed and compacted per <br /> project specifications. <br /> Slope grading and contouring occurred at various locations below elevation 9,450' on the PSSA <br /> slopes. Excess cut was stockpiled at the toe of the slope for later removal. <br /> A Cat dozer and excavator Geared out loose material from the closure drain area and prepared <br /> the subgrade for concrete collar placement. Ames also worked on prefabrication of the <br /> reinforcing steel for the concrete collars. Worked was temporarily halted in the Closure Drain <br /> area due to the accumulation of surface runoff into the sump of the drain from afternoon rain <br /> showers during the week. <br /> Cat dozers placed cut to fill near station AO+00 to A2+00. Structural fill was placed and <br /> compacted per project specifications. <br /> Slope grading and contouring work was performed at various locations below elevation 9,450' <br /> within the PSSA 2.5H: IV slopes. Excess cut was stockpiled temporarily or later removal. <br /> Cat excavators with rock hammers performed slope re-contouring of finished subgrade and broke <br /> oversized material in the subgrade downslope of stations A6+00 to A8+00. <br /> The Low Volume Solution Collection (LVSC) riser pipe trench was completed to finished <br /> subgrade elevations on the southeast comer of the PSSA slope. <br /> A Cat CS56 smooth drum roller compacted subgrade in various areas within PSSA and <br /> surrounding Phase 1 slopes. <br /> A Cat GPS D6 dozer rough graded in the Phase 2 Diversion Channel alignment near stations <br /> 24+00 to 28+00. <br /> Clay(SLF) Processing: <br /> Cameron Site: No clay mining or processing occurred at the Cameron Site. Approximately <br /> 244,860 tons of clay/soil liner fill (SLF) material has been produced at the Cameron site. SLF <br /> produced from the operation remains stockpiled at the Cameron Site for future use. <br /> Squaw Gulch Clay Borrow Site: Clay mining and processing occurred at the Squaw Gulch <br /> Clay Borrow Site. Approximately, 136,000 tons of soil liner fill material has been produced at this <br /> site to date. <br /> MLE2 WE 31 MAY 2014 FINAL Page 2 of 7 <br />
