(1) D6 LGP and (1) D4 Dozer were used to spread Operations layer 2 ft thick over deployed 8 oz/sy geotextile along middle of cell working to the north and west. Random samples of Operations layer were hand sieved in field with 1" screen during placement. Observed +3" Material in two loads. Contractor informed that material doesn't meet specification requirements. Placement discontinued at 2:30 pm Gravel Drainage Material Placement: 19-20 various types of end -dumps were used to import Gravel Drainage Material (GDM) from the Cemex Rock Plant until 4:30 pm.

(1) CAT D6 LGP dozer equipped with GPS spread GDM in the center of cell floor pushing north and west this morning beginning at 5:30 am. (1) CAT D6 LGP dozer equipped with GPS spread previously stockpiled GDM along northern toe of slope. (1) Laborer controlled wrinkles. GDM placement discontinued at approximately 11:30 pm due to moderate to heavy wrinkles observed in HDPE Liner. GDM import continued, with material stockpiled onto previously deployed GDM. A sample of imported GDM was tested for gradation in the field. The material met the project specifications. AES QA personnel monitored the placement and verified the depths of the placed LCRS gravel by using a dulled probe. Geotextile: RJ Gordon deployed and Great Basin sewed 8 oz/sy geotextile over GDM along middle portion of the cell heading west. (2) Laborers were used to hand roll Geotextile into place. (1) Laborer Observed using hand sewing machine to sew seams. Geocomposite: The remaining area of Geocomposite was deployed on the west end of Northern slope. Observed nylon ties secured at 3 foot intervals along length and 6 -inch intervals along width. Geotextile seams were sewn using hand sewing machine.
