M 1 4& re ® • Excess material graded to the toe of the Ball Mill slope northwest of the Load Out Bin (LOB) (day shift) Any oversized material encountered was reduced in size by a hammer hoe. Material was transported from the Surge area to SGVLF haul road stations 71 +00 to 73 +00 where it was placed and compacted as structural fill. Structural fill was placed and compacted downslope of Bench D stations D6 +00 to D8 +00 and on SGLVF haul road between stations 15 +00 to 20 +00 per project specifications. The material was hauled to the area from a stockpile located at SGLVF haul road stations 52 +00 to 54 +00. Slope grading occurred in the Phase 1 area at the following locations: • Above Bench A stations A14 +00 to A18 +00. • Above SGVLF haul road stations 48 +00 and 51 +00. • Above SGVLF haul road stations 55 +00 and 59 +00. • Down slope of Bench L stations 1-28 +00 and L36 +00. Any excess material generated from slope grading activities was stockpiled for subsequent removal and use as structural fill. A Cat loader built berms to accommodate 793 haul trucks along the SGVLF haul road at stations 15 +00 to 20 +00, 54 +00 to 80 +00, and 85 +00 to 87 +00. Cat dozers were re- contouring the SGVLF haul road at stations 15 +00 to 20 +00 and 54 +00 to 56 +00. Material was hauled from various locations along the SGVLF haul road between stations 38 +00 to 54 +00 and placed upslope of Bench A stations A20 +00 to A22 +00 to create a temporary loading ramp between stations A20 +00 and SGVLF haul road station 15 +00. Subgrade: No new Phase 1 subgrade was accepted during this reporting period. Refer to the figure in the MLE2 weekly report for November 8, 2014 for accepted subgrade in the Phase 1 area. Soil Liner Fill (SLF): SLF was hauled from the Cameron Clay Pit area and stockpiled below Bench F between stations F0 +00 and F10 +00. No new Phase 1 SLF was accepted during this reporting period. Refer to the figure in the MLE2 weekly report for November 8, 2014 for accepted SLF in the Phase 1 area. Cameron Site: SLF processing continued at the Cameron Site. Underdrain System: Primary Underdrain: Complete. Secondary Underdrain: No work was performed during this reporting period. Tertiary Underdrain: No work was performed during this reporting period. Leak Detection: Approximately 160 lineal feet of leak detection trench was completed per project specification and covered with soil liner fill downslope of Bench F station FF6 +50 to FF8 +00. 2014 -11 -15 -MLE2 WEEKLY FINAL Page 2 of 7
