ame0 <br />Earth 8 Environmental <br />centerline. Slope contouring was performed using various CAT dozers and various CAT <br />excavators. The material generated as the cut progressed was pushed down the slope. <br />D) Overburden to Stockpile <br />1) VLF <br />Oversize rock within the Phase 5 VLF fill area was removed from fill/cut areas and hauled to <br />the overburden stockpile area east of the east perimeter road near stations A29 +00 ( + / -) to <br />A32 +00 ( + / -) right of centerline. <br />E) Cut to Fill <br />1) VLF <br />A CAT 385 excavator was used to excavate structural fill material from between stations <br />J4 +00 ( + / -) and J10 +00 ( + / -), approximately 100 to 150 feet left of centerline. The structural <br />fill material was loaded into CAT 777 haul trucks with assistance from various CAT dozers. <br />Structural fill was between stations A36 +00 ( + / -) and A40 +00 ( + / -), approximately 50 to 100 <br />left of centerline and between stations between stations C0 +00 ( + / -) and C7 +50 ( + / -), <br />approximately 30 feet left of centerline to 30 feet right of centerline. Structural fill was placed <br />in 18" to 24" lifts using various CAT dozes. Each lift was moisture conditioned using a CAT <br />773 water truck (when necessary) and compacted using a 10 -ton vibratory smooth drum <br />compactor, passing over the entire fill surface at least 4 times (method compaction technique <br />was applicable). <br />Structural fill placement was also performed between stations E 16 +00 ( + / -) and E23 +00 ( + / -), <br />approximately 50 feet left of centerline to 200 right of centerline and between stations C2 +00 <br />( + / -) and C7 +50 ( + /- ),approximately 200 feet left of centerline to 20 feet right of centerline. <br />Cut /fill operations were performed using various CAT dozers and excavators. Structural fill <br />was placed in 18" to 24" lifts. Each lift was moisture conditioned using a CAT 773 water truck <br />(when necessary) and compacted using a 10 -ton vibratory smooth drum compactor, passing <br />over the entire fill surface at least 4 times (method compaction technique was applicable). <br />F) Soil Liner Fill <br />1) VLF <br />Soil liner fill (SLF) placement continued in the areas shown in Figure 3, hauling from the East <br />Cresson Clay borrow. Subgrade was approved and moisturized prior to placement using a <br />tandem -axel water truck. Placement was performed using one CAT D -6 dozer, and one CAT <br />skid steer loader in a one -foot compacted lift. Moisture conditioning was performed using a <br />tandem -axel water truck and compaction was performed using a 10 -ton vibratory smooth drum <br />compactor. Nuclear density testing, moisture verification, and depth checks were performed in <br />the geomembrane deployment areas throughout the week. All test results were within project <br />specifications and all test locations were surveyed by Ames. <br />G) PSSA Ore Slope Construction <br />1) VLF <br />Construction of the remaining portion of the PSSA ore slope continued between stations <br />G18 +50 ( + / -) and G31 +00 ( + / -), approximately 0 to 225 feet left of centerline using a CAT D- <br />6 LGP dozer and a CAT 279 skid steer loader. Existing ore was pushed over the previously <br />VLF Weekly Report WE 07.03.10.D <br />
