IddrIll. <br />amec <br />Earth & Environmental <br />C) Overburden to Stockpile: <br />1) VLF <br />Oversize material was hauled to the Joe Dandy Main Cresson backfill intermittently during the <br />week. <br />2) VLF, PSSA Haul Road <br />No work performed during the week. <br />D) Cut to Fill <br />1) VLF <br />Structural Fill was excavated from the LOB Delivery Road cut from stations 1+00 (+/-) to <br />4+00 (+/-), and the proposed water storage tank location. Structural fill was placed on the VLF <br />between stations K2+50 (+/-) and K9+00 (+/-), 0 to 100 feet right of the shoulder and between <br />stations 6+50 (+/-) to 9+50 (+/-), 0 to 150-feet left of the shoulder of PSSA Haul Road using <br />available CAT 777 and 40-Ton articulating haul trucks. Structural Fill was placed using one <br />CAT D-8 dozer. Lift thickness was 18" to 24" (based on rock size). Field observations <br />indicated there was greater than 30% rock retained on the 3/4 -inch sieve. Moisture conditioning <br />of the fill was performed using a CAT 773-water truck. Each lift was compacted with a smooth <br />drum vibratory roller a minimum of 4-passes over the entire surface (method compaction <br />technique is applicable). Ambient temperatures were monitored during the shift. No frozen <br />fill was placed. <br />2) VLF, PSSA Haul Road <br />Structural Fill material from the LOB Delivery Road cut from stations 1+00 (+/-) to 4+00 (+/-) <br />and 15+50 (+/-) to 17+00 (+/-) was hauled to the VLF using CAT 777 and 40-ton articulating <br />haul trucks. The Structural Fill material was placed and compacted between stations K4+00 <br />(+/-) to K10+00 (+/-) right and left of centerline 40-feet. One Cat D-8 dozer was used to spread <br />the structural fill in 18" to 24" inch lifts (based on rock size). The fill was moisture conditioned <br />using a water truck. Compaction was achieved using a CAT 563 vibratory smooth drum roller <br />to pass over the entire fill surface a minimum of 4-passes. <br />Material suitable as Structural Fill was excavated from the proposed water storage tank <br />location and placed on the PSSA Haul Road between stations K1+00 (+/-) and K8+50 (+/-) <br />using available 40-Ton articulating haul trucks. Structural Fill was placed in 18" to 24" inch <br />lifts (based on rock size). Field observations indicated there was greater than 30% rock <br />retained on the 3/4 -inch sieve. Moisture conditioning of the fill was performed using a CAT <br />773-water truck. Each lift was compacted with a smooth drum vibratory roller a minimum of <br />4- passes over the entire surface (method compaction technique is applicable). Ambient <br />temperatures were monitored during the shift. No frozen fill was placed. <br />3) Sediment Collection Pond <br />No work performed during the week. <br />Sheet 2 of 6 <br />VLF Weekly Report WE 05.16.09.D.doc
