amec <br />Earth & Environmental <br />and K6+00 (+/-), approximately 100 to 300 feet right of centerline. Slope contouring was <br />performed using various CAT dozers and various CAT excavators. Material generated as the <br />cut progressed was pushed down the slope. <br />D) Overburden to Stockpile <br />1) VLF <br />No work performed during the week. <br />E) Cut to Fill <br />1) VLF <br />A CAT 385 excavator was used to excavate structural fill material from between stations <br />E14+00 (+/-) and E16+50 (+/-), approximately 75 to 100 feet left of centerline; and K0+00 <br />(+/-) and K5+00 (+/-), approximately 0 to 50 right of centerline. The structural fill material was <br />loaded into CAT 777 haul trucks and hauled to fill areas. <br />Structural fill was placed between stations C0+00 (+/-) and C7+00 (+/-), approximately 60 feet <br />left of centerline to 60 feet right of centerline and between stations K0+00 (+/-) and K5+00 <br />(+/-), approximately 0 to 50 feet right of centerline. Structural fill was placed in 18" to 24" lifts <br />using various CAT dozers. 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 />Ambient temperatures were monitored and fill placement was not performed during ambient <br />temperatures below 32°F. <br />Blast pattern drilling was performed between stations E10+50 (+/-) and E17+00 (+/-), <br />approximately 20 to 150 feet right of centerline. Blasting was performed on Monday <br />(5/10/2010), Wednesday (5/12/2010), Thursday (5/13/2010), and Saturday 5/15/2010. No <br />blasting was performed Tuesday (5/11/2010) and Friday (5/15/2010). <br />F) Soil Liner Fill <br />1) VLF <br />Soil liner fill (SLF) placement began between stations B0+50 (+/-) and B7+50 (+/-), <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 C. Placement was performed using a John Deere 729 dozer, two CAT <br />D-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 05.15.10.D
