amec <br />Earth 8 Environmental <br />E) Slope Contouring <br />1) VLF <br />Slope contouring was performed between stations A12+00 (+/-) and A18+00 (+/-), <br />approximately 100 to 300 feet left of centerline. Contouring was performed using a CAT D-10 <br />dozer and a CAT D-9 dozer. Material generated as the cut progressed was pushed down the <br />slope. <br />F) Overburden to Stockpile <br />1) VLF <br />Overburden was hauled to the overburden stockpile area east of the east perimeter road near <br />stations A28+00 (+/-) to A36+00 (+/-) from between stations A9+00 (+/-) and A10+75 (+/-), <br />approximately 40 to 100 feet left of centerline. Overburden was hauled using 40-ton haul <br />trucks loaded by a John Deere 850 excavator. <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 />G) Cut to Fill <br />1) VLF <br />A John Deere 850D excavator, a Komatsu 800 excavator, and a CAT 375 excavator were used <br />to excavate structural fill material from the following areas: between stations A6+50 (+/-) and <br />A11+50 (+/-), approximately 50 to 150 feet left of centerline; between stations E1+00 (+/-) and <br />E2+00 (+/-), approximately 75 to 100 feet right of centerline; between stations H28+00 (+/-) <br />and H30+00 (+/-), approximately 0 to 75 feet right of centerline; between J0+00 (+/-) and <br />J10+00 (+/-), approximately 50 to 200 feet right of centerline; and between stations J20+00 <br />(+/-) and J21+50 (+/-), approximately 40 to 50 right of centerline. The structural fill material <br />was transported using 777 haul trucks and 40-ton articulating haul trucks. <br />Structural fill was placed between stations A38+00 (+/-) and A40+00 (+/-), approximately 0 to <br />250 feet left of centerline. Structural fill was placed using CAT dozers in 18" to 24" lifts <br />(based on rock size). Moisture conditioning of the fill was performed using a CAT 773-water <br />truck (when necessary). Each lift was compacted with a 10-ton smooth drum vibratory <br />compactor passing over the entire surface at least 4 times (method compaction technique is <br />applicable). <br />Structural fill was placed between stations E3+00 (+/-) and E12+00 (+/-), approximately 150 to <br />200 feet left of centerline. Structural fill was placed using CAT dozers in 18" to 24" lifts <br />(based on rock size). Moisture conditioning of the fill was performed using a CAT 773-water <br />truck (when necessary). Each lift was compacted with a 10-ton smooth drum vibratory <br />compactor passing over the entire surface at least 4 times (method compaction technique is <br />applicable). <br />Structural fill was placed between stations F8+00 (+/-) and F 10+00 (+/-), approximately 150 to <br />200 feet left of centerline. Structural fill was placed using CAT dozers in 18" to 24" lifts <br />(based on rock size). Moisture conditioning of the fill was performed using a CAT 773-water <br />VLF Weekly Report WE 08.15.09.D.doc
