ame <br />Earth & Environmental <br />3) Topsoil Relocation <br />The lower topsoil stockpile, south of the LOB Delivery road, was contoured through out the <br />week using a CAT D-6 LGP dozer. <br />C) Overburden to Stockpile: <br />1) VLF <br />Oversize rock within in the Phase 5 VLF fill area was stockpiled using a CAT D-9 dozer for <br />future haul to the Joe Dandy Main Cresson Backfill. Oversize materials previously stockpiled <br />were moved to the east slope of the Phase 5 east perimeter road using a CAT D-6 dozer and a <br />CAT 966 front-end loader. <br />2) VLF Subgrade Preparation <br />Subgrade preparation was performed between stations A27+00 (+/-) and A38+00 (+/-), <br />approximately 50 to 300 feet left of centerline. The areas were scarified to a depth of 12" to 18" <br />inches using a CAT D-9 dozer and moisture conditioned using a CAT 773-water truck. <br />Compaction was performed using a CAT 563 vibratory smooth drum compactor passing over <br />the subgrade surface with 4-passes. No unsuitable materials were found during subgrade <br />preparation. <br />3) VLF, PSSA Haul Road <br />No work performed during the week. <br />D) Cut to Fill <br />1) VLF <br />A John Deere 850D excavator and Komatsu 800 excavator excavated structural fill material <br />between stations J1+50 and J14+50 approximately 75 to 200 feet left of centerline. The <br />structural fill material was transported using 777 haul trucks and 40-ton articulating haul <br />trucks. Structural fill was placed in the VLF between stations A17+00 (+/-) and A29+00 (+/-), <br />approximately 50 to 400 feet left of centerline. Structural Fill was placed using one CAT D-9 <br />dozer and a CAT D-10 dozer. Lift thickness was 18" to 24" (based on rock size). Moisture <br />conditioning of the fill was performed using a CAT 773-water truck. Each lift was compacted <br />with a smooth drum vibratory roller a minimum of 4-passes over the entire surface (method <br />compaction technique is applicable). <br />Rockbreakers began drilling a shot pattern between stations A17+50 (+/-) to A20+00(+/-) <br />using three track mounted drill rigs. This area is scheduled to be shot next week. <br />Suitable structural fill material excavated from the LOB Delivery Road cuts was hauled to the <br />PSSA Embankment fill and end dumped on the fill. This material will be spread and placed at <br />a later date. <br />2) VLF, PSSA Haul Road <br />No work performed during the week. <br />3) Sediment Collection Pond <br />No work performed during the week. <br />Sheet 2 of 6 <br />VLF Weekly Report WE 06.06.09.D.doc
