(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 middle of Stockpile 2 into the Power Screen screening plant. Screened product was stockpiled in a cone using a <br />belt stacker to keep the screened soil separate from unprocessed soil. (1) 950 M Loader was used relocate +1" from under <br />belt into separate stockpile. (1) Sample collected from today's stacker belt stockpile. Full gradation in field lab was <br />performed. Lab results indicated 100 % Passing 1" Screen. Screening operation ended at 4:30 pm. <br />Operations Layer Placement: Hyundai 300 loading (2) Cat 745 Dump Trucks with Screened Operations Layer for placement <br />on cell floor. (1) D6 LGP Dozer was used to spread Operations layer 2 ft thick over deployed 8 oz geotextile along southern <br />edge of cell working north and west. Random samples of Operations layer were hand sieved in field with 1" screen during <br />placement. Observed 100% passing 1" screen. <br />Gravel Drainage Material Placement: 15-17 tandem end -dumps were used to import Gravel Drainage Material (GDM) from <br />Cemex Rock Plant until 4:30 pm. Observed 3 ft of GDM between end dumps and underlying geosynthetics. (1) Cat D6 LGP <br />dozer equipped with GPS spreading GDM along northeast corner of cell floor this morning beginning at 5:00 am. (1) Laborer <br />controlled wrinkles. GDM placement discontinued at approximately 11:30 due to moderate to heavy wrinkles observed in <br />HDPE Liner. GDM import continued, with material being stockpiled on previously deployed GDM. AES QA personnel <br />monitored the placement and verified the depths of the placed LCRS gravel by using a dulled probe. GDM sample was <br />collected at 11:00. Field gradation indicates GDM meeting required specifications. <br />GDM Gravel Summary <br />8/19/15 -1032 tons <br />Total Tonnage - 7,946 tons <br />Geotextile: (3) Great Basin employees on site this morning to deploy 8 oz/sy over graded GDM.
