(1) Hitachi 300 <br />excavator, (1) CAT D6 dozer (1) 950 M Loader used to perform screening operations. The Hitachi 300 used to load soil from <br />the middle of Stockpile 2 into the Power Screen screening plant. Screened product was stockpiled in a cone using a belt <br />stacker to keep the screened soil separate from unprocessed soil. At 10:30 am, Hitachi 300 parked for balance of the day and <br />Hyundai 480 added to screening operation. (1) 950 M Loader was used relocate +1" from under belt into separate stockpile. <br />(1) Sample was collected from today's stacker belt stockpile. Full gradation was performed in field lab. Lab results indicated <br />100% Passing 1" Screen. Screening operation ended at 4:30 pm. <br />Operations Layer Placement: (1) Hyundai 480 excavator loaded (2) Cat 745 Dump Trucks with Screened Operations Layer <br />for placement on cell floor. (1) Cat D4 Dozer was added to operation today. Cat D4 and Cat D6 LGP Dozer were used to spread <br />Operations layer 2 ft thick over deployed 8 oz geotextile along southern edge of cell working north and west. Random <br />samples of Operations layer were hand sieved in field with 1" screen during placement. Observed 100% passing 1" screen. <br />Hauling operation discontinued at 10:30 am. (2) Cat 745 Dump Trucks parked. Hyundai 480 moved to screening operation. <br />Gravel Drainage Material Placement: 19-20 various type of end -dumps were used to import Gravel Drainage Material <br />(GDM) from Cemex Rock Plant until 4:00 pm. Observed 3 ft of GDM between end dumps and underlying geosynthetics. (1) <br />CAT D6 LGP dozer equipped with GPS spread GDM in the northeast corner of cell floor beginning at 5:00 am. (1) Laborer <br />controlled wrinkles. GDM placement discontinued at approximately 2:30 pm due to moderate to heavy wrinkles observed in <br />HDPE Liner. GDM import continued, with material being stockpiled onto previously deployed GDM using Cat D4 and Cat D6 <br />LGP Dozers. AES QA personnel monitored the placement and verified the depths of the placed LCRS gravel by using a dulled <br />probe. (1) GDM sample was collected at 11:00 am. Field gradation indicated GDM met required specifications. <br />GDM Gravel Summary <br />8/20/15 -1057 tons <br />Total Tonnage - 9003 tons <br />Geotextile: No activity observed today. <br />Leachate Collection Pipe: Contractor continued placement of the Middle Leachate Collection Pipe. Approximately 250 If of <br />6" perforated HDPE pipe was placed today. (1) Cat 950 M Loader operating over completed operations layer soil was used to <br />place coarse gravel over 6" Perforated HDPE Pipe. Coarse gravel and 6" HDPE pipe were wrapped in 8 oz/sy Geotextile. <br />Gravel was measured to be a minimum of 1 ft in depth and a minimum of 4 ft in width. Geotextile was measured to have a 2ft <br />minimum overlap. <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. (1) CAT 623 paddlewheel scraper. (1) Power Screen, (1) Belt Stacker, (1) Hyundai 480LC excavator, (1) <br />CAT D6T dozer, (2) Cat 745 Dump Truck, (1) Cat 950 M Loader (1) CAT D4 Dozer <br />Problems/Resolutions. <br />Visitors: <br />Reviewed By: M.
