amec : <br /> A Cat dozer cut material from above ADR haul road stations 60+00 to 65+00 and pushed it <br /> downslope where it was stockpiled for later placement as structural fill. <br /> A Cat 928 loader moved material from Bench B to the PSSA toe-berm above the 9450 elevation <br /> and placed it as structural fill. <br /> A Cat 330 excavator with a rock hammer broke oversized rock on the subgrade downslope of <br /> station A22+00 in the PSSA. <br /> Soil liner fill (SLF)was transported in Cat 740 haul trucks from the Squaw Gulch SLF stockpile to <br /> the stockpile area above station DD5+00. SLF was also hauled and placed in areas of the PSSA <br /> below stations A16+00 to A18+00. <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 /> A Cat dozer reworked the soil liner fill finished grade downslope of stations A10+00 to Al2+00 <br /> due to surface water runoff. The area was later reapproved for geomembrane placement. <br /> Cat dozers placed SLF in approximately 18-inch lifts downslope between stations Al2+00 to <br /> A18+00 and on the ADR haul road from stations 0+00 to 6+00 downslope to the PSSA floor. <br /> Subgrade: <br /> The following subgrade areas in the PSSA were compacted per project specification to finished <br /> grade, inspected and certified for soil liner fill (SLF) placement <br /> From stations A16+00 to A18+00 to the PSSA floor <br /> ADR haul road stations 0+00 to 7+00 and the slope below those stations to the PSSA <br /> floor <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 specification to finished grade, <br /> inspected and certified for geomembrane placement: <br /> r From stations A10+00 to Al2+00 to the PSSA floor <br /> v ADR haul road stations 0+00 to 6+00 and the slope below those stations to the PSSA <br /> floor <br /> The southern portion of the PSSA floor <br /> See the attached SLF acceptance map for all accepted locations. <br /> SLF Processing: <br /> Cameron Site: No soil liner fill mining or processing occurred at the Cameron Site. <br /> Approximately 244,860 tons of SLF material has been produced and remains stockpiled at the <br /> Cameron Site for future use. The soil liner fill processing equipment rema ns at the Cameron site. <br /> No new processing was performed during this reporting period. <br /> Underdrain System: <br /> Primary Underdrain: Complete. <br /> Secondary Underdrain: Approximately 360 lineal feet of underdrain extending from station <br /> A21+00 to the PSSA floor was trenched, lined with geofabric, filled with underdrain material, and <br /> partially covered with select structural fill. Additional select structural fill placement is required to <br /> complete the underdrain. Sample OF-11-R was collected from this area. <br /> 2014.07.26-MLE2 WEEKLY FINAL Pege 2&7 <br />
