(1) Hitachi 300 <br />excavator, (1) CAT D6 dozer (1) 950 M Loader was used to perform screening operations. The Hitachi 300 was used to load <br />soil from the western end of Stockpile 2 into the Power Screen screening plant. Screened product was stockpiled in a cone <br />using a belt stacker to keep the screened soil separate from unprocessed soil. (1) 950 M Loader was used relocate +1" from <br />under the belt into separate stockpile. (1) Sample collected from today's stacker belt stockpile. Full gradation was performed <br />in field lab. Lab results indicated 100 % Passing 1" Screen. Screening operation ended at 3:30 pm. <br />Operations Layer Placement: (1) Hyundai 300 loaded (2) Cat 745 Dump Truck with Screened Operations Layer for <br />placement on cell floor. (1) D6 LGP Dozer was used to spread Operations layer 2 ft thick over deployed 8 oz/sy geotextile <br />along middle of cell working to the north and west. Random samples of Operations layer were hand sieved in field with 1" <br />screen during placement. Observed 100% passing 1" screen. Placement discontinued at 3:30pm <br />Gravel Drainage Material Placement: 20-23 various types of end -dumps were used to import Gravel Drainage Material <br />(GDM) from the Cemex Rock Plant until 4:30 pm. Observed trucks operating on at least 3 ft of GDM overlying the <br />Geomembrane. (1) CAT D6 LGP dozer equipped with GPS spread GDM in the center of cell floor pushing west this morning <br />beginning at 5:00 am. (1) Laborer controlled wrinkles. GDM placement discontinued at approximately 11:30 pm due to <br />moderate to heavy wrinkles observed in HDPE Liner. GDM import continued, with material stockpiled onto previously <br />deployed GDM between Northern Leachate Collection Pipe and toe of slope. Stockpiling was supported by the Cat D6 LGP <br />Dozer and Cat D4 Dozer. AES QA personnel monitored the placement and verified the depths of the placed LCRS gravel by <br />using a dulled probe. (1) GDM sample was collected at 9:30 am. Field gradation indicated the GDM met the specifications. <br />Geotextile: Great Basin deployed and sewed 8 oz/sy geotextile along southeastern and middle portion of the cell. (6) <br />Laborers were used to hand roll Geotextile into place. Observed seams sewn using hand sewing machine. <br />Geocomposite: No activity observed today. <br />Leachate Collection Pipe: No activity observed today. <br />24" HDPE Riser Pipe: No activity observed today. <br />Equipment Onsite: (1) CAT D6T LGP dozer, (2) water trucks, (1) Hitachi 300 excavator, (1) CAT TH160B folk lift, (1) John <br />Deere 410 Backhoe.
