ame <br />Earth 8 Environmental <br />compactor. The entire surface of the subgrade was compacted with at least 4-passes. These <br />areas were inspected by an AMEC representative and accepted for structural fill placement. <br />D) 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 />E) Cut to Fill <br />1) VLF <br />A CAT D-9 dozer was used to structural fill placement between stations K0+00 (+/-) and <br />K2+00 (+/-), approximately 0 to 100 right of centerline. The material pushed from the cut area <br />just south of the fill area. The structural fill material was spread in 18" to 24" lifts. Each lift <br />was moisture conditioned using a CAT 773 water truck (when necessary) and compacted using <br />a 10-ton vibratory smooth drum compactor, passing over the entire fill surface at least 4 times <br />(method compaction technique is applicable). <br />A CAT D-9 dozer and a CAT D-10 dozer were used for structural fill placement between <br />stations J21+00 (+/-) and J24+00 (+/-), approximately 150 to 200 right of centerline. The <br />material pushed from the cut area between stations J17+00 (+/-) and J21+00 (+/-), <br />approximately 0 to 100 right of centerline. The structural fill material was spread in 18" to 24" <br />lifts. Each lift was moisture conditioned using a CAT 773 water truck (when necessary) and <br />compacted using a 10-ton vibratory smooth drum compactor, passing over the entire fill <br />surface at least 4 times (method compaction technique is applicable). <br />A CAT D-9 dozer and a CAT D-8 dozer were used for structural fill placement between <br />stations J16+00 (+/-) and J20+00 (+/-), approximately 150 to 200 left of centerline. The <br />material pushed from the cut area between stations J16+00 (+/-) and J20+00 (+/-), <br />approximately 300 to 350 left of centerline. The structural fill material was spread in 18" to <br />24" lifts. Each lift was moisture conditioned using a CAT 773 water truck (when necessary) <br />and compacted using a 10-ton vibratory smooth drum compactor, passing over the entire fill <br />surface at least 4 times (method compaction technique is applicable). <br />A CAT D-8 dozer was used for structural fill placement between stations J21+00 (+/-) and <br />J24+00 (+/-), approximately 150 to 200 right of centerline. The material pushed from the cut <br />area between stations J18+00 (+/-) and J22+00 (+/-), approximately 0 to 250 right of <br />centerline. The structural fill material was spread in 18" to 24" lifts. Each lift was moisture <br />conditioned using a CAT 773 water truck (when necessary) and compacted using a 10-ton <br />vibratory smooth drum compactor, passing over the entire fill surface at least 4 times (method <br />compaction technique is applicable). <br />Sheet 2 of 8 <br />VLF Weekly Report WE 08.01.09.D.doc
