ameO <br />Earth & Environmental <br />between stations H8+00 (+/-) and H25+00 (+/-), approximately 25 to 250 feet right of <br />centerline; and between stations J14+00 (+/-) and J19+00 (+/-), approximately 0 to 150 feet <br />right of centerline. Slope contouring was performed using various CAT dozers. Material <br />generated as the cut progressed was pushed down the slope. <br />E) 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 />F) Cut to Fill <br />1) VLF <br />A CAT 385 excavator and a John Deere 850 excavator were used to excavate structural fill <br />material from the following areas: between stations A16+00 (+/-) and A18+00 (+/-), <br />approximately 100 to 150 feet left of centerline; between stations E6+00 (+/-) and E14+00 <br />(+/-), approximately 50 feet left of centerline to 200 feet right of centerline; between stations <br />H 18+00 (+/-) and H22+50 (+/-), approximately 250 to 300 feet left of centerline; between <br />stations J23+00 (+/-) and J28+50 (+/-), approximately 100 to 150 feet right of centerline; and <br />between stations K4+50 (+/-) and K8+00 (+/-), approximately 150 to 175 right of centerline. <br />The structural fill material was loaded into CAT 777 haul trucks and hauled to fill areas. <br />Prior to structural fill placement existing fill areas were ripped and frost was allowed to thaw <br />or was removed. Existing fill temperature were monitored and found to be above 32°F before <br />fill placement. An AMEC representative monitored ambient temperatures on an hourly basis <br />during fill placement. Fill temperatures were monitored during ambient temperatures below <br />32°F and averaged 330F to 45°F. <br />Structural fill was placed in the following areas: between stations A8+00 (+/-) and A22+00 <br />(+/-), approximately 20 feet left of centerline to 20 feet right of centerline; between stations <br />C0+00 (+/-) and C5+00 (+/-), approximately 50 feet left of centerline to 50 feet right of <br />centerline; and between stations J15+00 (+/-) and J22+00 (+/-), approximately 150 feet left of <br />centerline to 20 feet right of centerline. Structural fill was placed in 18" to 24" lifts using <br />various CAT dozers. Each lift was moisture conditioned using a CAT 773 water truck (when <br />necessary) and compacted using a 10-ton vibratory smooth drum compactor, passing over the <br />entire fill surface at least 4 times (method compaction technique is applicable). Ambient and <br />fill temperatures were monitored and recorded during fill placement. <br />Blast pattern drilling was performed between stations J25+00 (+/-) and J28+00 (+/-), <br />approximately 50 feet left of centerline to 50 feet right of centerline. No blasting was <br />performed during the week. <br />G) Material Processing <br />1) South Cresson Clay Processing Area <br />Processing of Soil Liner Fill material continued at the South Cresson Clay Process. A CAT D-8 <br />dozer, a CAT 320 excavator, and a CAT 966 front-end loader were used to process the material. <br />VLF Weekly Report WE 01.23.10.D.doc
