Some of the material was also hauled <br />upslope of stations D0 +00 to D2 +00. The material was placed as structural fill. <br />An excavator removed material from upslope of station D10 +00 and loaded it into Cat 740 trucks. <br />The material was hauled to stations F24 +00 to F26 +00 where it was placed as structural fill. <br />Furthermore, two dozers pushed material downslope to the fill area at stations F24 +00 to F26 +00 <br />from stations H18 +00 to H2O +00. <br />The Phase 2 Diversion Channel was compacted with a smooth drum roller and prepared for <br />geofabdc and riprap placement east of the Phase 2 pond. <br />Subgrade: <br />All subgrade areas in the PSSA footprint have been certified for SLF placement per project <br />technical specifications. <br />The subgrade was inspected and certified below stations F0 +00 to F10 +00 in the Phase 1 area. <br />Soil Liner Fill: <br />The following SLF areas in the PSSA were compacted per project specifications to finished <br />grade, inspected, and certified for geomembrane placement: <br />r Between approximate ADR haul road stations 3 +00 to 7 +00 and the central portion of the <br />PSSA floor adjoining previously approved SLF (reapproved). <br />r Between approximate ADR haul road stations 7 +00 to 10 +00 and the northern portion of <br />the PSSA floor adjoining previously approved SLF. <br />Soil liner fill was reconditioned on the PSSA floor and the northern PSSA slopes. <br />A Cat smooth drum roller compacted the SLF surface from Bench A to the PSSA floor between <br />stations A20 +00 to A22 +00. <br />Ames cut through a small area of secondary liner to expose and cap the temporary embankment <br />drain on the south side of the PSSA.
