Nogales Contractor: R J Gordon Construction, Inc. M. Hu and Weather: Clear - Warm Wind: 0-10 mph. Tem erature: ARprox. range 60- 91 F Other: The contractor worked from 5:00 am to 4:30 pm. Excavation: No activity observed. Access Road: No activity observed. Operations Layer Processing: Contractor continued screening of operations stockpile today at 5:30 am. (1) Hyundai 480LC, (1) Hitachi 300 excavator and (1) CAT D6 dozer used to perform screening operations. The Hyundai 480LC was used to load soil from the east end of Stockpile 2 into the Power Screen screening plant. Hitachi 300 Excavator used to stage screened operations material for future haul and remove waste material from under screen plant and belt into separate stockpile. D6 Dozer used to support Hyundai Excavator. Screened product was stockpiled in a cone using a belt stacker to keep the screened soil separate from unprocessed soil. At approximately 7:00 am, a sample of the operations layer was collected from screened stockpile and a full gradation was run in the field lab. Lab Results indicate 100% passing 1" sieve. Gravel Drainage Material Placement: 5:00 am (1) Cat D6 LGP dozer equipped with GPS spread GDM from yesterday's delivery that had been stockpiled. Placement had discontinued on 8/11/15 due to wrinkles. Contractor began spreading early to minimize wrinkles in liner. At 6:30 am, 17-18 tandem end -dumps used to import Gravel Drainage Material (GDM) from Cemex Rock Plant until 4:30 pm. End dumps backed up onto GDM to off load material. Observed a minimum of 3ft of GDM between haul equipment and underlying HDPE Liner at all times during delivery operations. Contractor has placed temporary plywood sheets, in a second location, over previously installed Leachate collection pipe along South portion of cell. Temporary plywood to be removed upon completion of GDM placement. (1) Cat D6 LGP dozer equipped with GPS spreading GDM along southeast portion of cell floor. (1) Laborer used to control wrinkles. GDM spreading discontinued at approximately 2:00 pm due to moderate to heavy wrinkles observed in HDPE Liner. GDM import continued, with material being stockpiled on previously deployed GDM. AES QA personnel monitored the placement and verified the depths of the placed LCRS gravel by using a dulled probe. At approximately 10:00 am, a sample of the GDM was collected from finished floor and a full gradation was run in the field lab. QA Manager informed of gradation results. On a couple screens the sand was outside of the approved submittal limits but it met the passing No. 4 and No 200 screens. Contractor was notified. Geotextile: RJ Gordon deployed (1) panel of 8 oz/sy geotextile approximately 70 ft long in the center of center of sump under proposed 6" perforated HDPE Leachate Collection Pipe.

(3) Laborers and (1) Cat 950 M Loader used to complete Leachate Collection Pipe into the Sump. Loader operating over completed operations layer soil was used to place coarse gravel over 6" Perforated HDPE Pipe. Coarse gravel and 6" HDPE pipe wrapped in 8 oz/sy Geotextile. Depth of Gravel was measured to be a minimum of 1ft in depth and a minimum of 4ft in width. Geotextile was measured to have a 2 ft minimum overlap. Equipment Onsite: (1) CAT D6T LGP dozer, (2) water trucks, (1) Hitachi 300 excavator, (1) CAT TH160B folk lift, (1) CAT 430D backhoe. (1) CAT 623 paddlewheel scraper.
