ame0 <br />Earth & Environmental <br />stations G4 +00 ( + / -) and G7 +00 ( + / -), approximately 0 to 100 feet left of centerline; between <br />stations G24 +00 ( + / -) and G30 +00 ( + / -), approximately 0 to 100 feet left of centerline; <br />between stations H4 +00 ( + / -) and H12 +00 ( + / -), approximately 50 and 150 feet left of <br />centerline; and between stations K0 +00 ( + / -) and K8 +00 ( + / -), approximately 100 feet left of <br />centerline to 200 feet right of centerline. Slope contouring was performed using various CAT <br />dozers and various CAT excavators. Material generated as the cut progressed was pushed <br />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 areas and hauled to the <br />overburden stockpile area east of the east perimeter road near stations A28 +00 ( + / -) to A36 +00 <br />( +/ -). <br />E) Cut to Fill <br />1) VLF <br />A CAT 385 excavator was used to excavate structural fill material from between stations <br />E 12 +00 ( + / -) and E 14 +50 ( + / -), approximately 75 to 100 feet left of centerline. The structural <br />fill material was loaded into CAT 777 haul trucks and hauled to fill areas. <br />Structural fill was placed between stations C0 +00 ( + / -) and C7 +00 ( + / -), approximately 75 feet <br />left of centerline to 75 feet right of centerline and between stations F5 +00 ( + / -) and F10 +00 <br />( + / -), approximately 100 feet left of centerline to 20 feet right of centerline. Structural fill was <br />placed in 18" to 24" lifts using various CAT dozers. Each lift was moisture conditioned using a <br />CAT 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). Ambient temperatures were monitored and fill placement was not performed <br />during ambient temperatures below 32 °F. <br />Blast pattern drilling was performed between stations E7 +50 ( + / -) and E10 +50 ( + / -), <br />approximately 75 to 200 feet right of centerline. Blasting was performed on Monday <br />(5/3/2010), Tuesday (5/4/2010), Wednesday (5/5/2010), and Friday (5/7/2010). No blasting <br />was performed Thursday (5/6/2010) and Saturday (5/8/2010). <br />F) Soil Liner Fill <br />1) VLF <br />Soil liner fill (SLF) placement began between stations B0 +50 ( + / -) and B 13 +00 ( + / -), <br />approximately 0 to 550 feet right of centerline, hauling from the East Cresson Clay borrow. <br />Subgrade was approved and moisturized prior to placement. The area included in placement is <br />shown in Attachment B. Placement was performed using a John Deere 729 dozer, two CAT D- <br />6 dozers, and a CAT skid steer loader in a one -foot three -inch ( + / -) loose lift. Moisture <br />conditioning of subgrade prior to placement and of SLF was performed using a tandem -axel <br />water truck. Compaction of the material was not performed during the week. Moisture content <br />and placement of the material was observed by an AMEC field representative. Ames was <br />informed of current moisture contents and the importance of maintaining the moisture in the <br />SLF. Ames stated they would keep the moisture in the SLF until geomembrane is deployed. <br />No SLF material was placed during ambient temperatures below 32 °F. <br />VLF Weekly Report WE 05.08.10.D <br />
