(1) D6 LGP and (1) D4 Dozer were used to spread Operations layer 2 ft thick over deployed 8 oz/sy <br />geotextile along middle of cell working to the north and west. Random samples of Operations layer were hand sieved in field <br />with 1" screen during placement. Observed 100% passing 1" screen. Placement discontinued at 2:30 pm <br />Gravel Drainage Material Placement: 19-20 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 north and west this <br />morning beginning at 5:30 am. (1) CAT D6 LGP dozer equipped with GPS spread previously stockpiled GDM along Northern <br />toe of slope. (2) Laborer controlled wrinkles. GDM placement discontinued at approximately 10:30 pm due to moderate to <br />heavy wrinkles observed in HDPE Liner. GDM import continued, with material stockpiled onto previously deployed GDM. <br />AES QA personnel monitored the placement and verified the depths of the placed LCRS gravel by using a dulled probe. <br />Geotextile: RJ Gordon deployed and Great Basin sewed 8 oz/sy geotextile over GDM along middle portion of the cell heading <br />west. (2) Laborers were used to hand roll Geotextile into place. (1) Laborer observed using hand sewing machine to sew <br />seams. <br />Geocomposite: Geocomposite deployed on West end of Northern slope. Observed nylon ties secured at 3 foot intervals along <br />length and 6 -inch intervals along width. Geotextile seams were sewn using hand sewing machine. Installation resulted in <br />horizontal seams on the slope. The seams were constructed in accordance to the specifications and guidance from the <br />Engineer. At 2:30, (1) John Deere 410 Backhoe and (1) Laborer removed soil to expose damaged Geocomposite along Area 1 <br />tie-in to the north. (8) Locations have been identified as requiring repair.

(1) John Deere 410 Backhoe and (1) Cat 950 M Loader <br />operating over completed operations layer soil was used to place coarse gravel over 6" Perforated HDPE Pipe. Coarse gravel <br />and 6" HDPE pipe was wrapped in 8 oz/sy Geotextile. Gravel was measured to be a minimum 1 ft deep and a minimum 4 ft <br />wide. Geotextile was measured to have a 2 ft 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.
