amen <br />Earth & Environmental <br />C) Overburden to Stockpile: <br />1) VLF <br />Oversize was hauled to the Joe Dandy Main Cresson backfill intermittently during the week. <br />2) VLF, PSSA Haul Road <br />No work performed during the week. <br />D) Cut to Fill <br />1) VLF <br />No work performed during the week. <br />2) VLF, PSSA Haul Road <br />Structural Fill material from the LOB Delivery Road cut from stations 1+00 (+/-) to 3+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 K10+00 <br />(+/-) to K4+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 <br />compactor to pass over the entire fill surface at least 4 times. Ambient temperatures remained <br />above 32°F during fill placement. <br />3) Sediment Collection Pond <br />Additional Structural Fill was placed along the west side of the pond. Soil Liner Fill was <br />placed in the pond bottom and placed on the slopes later in the week. 40-Ton articulating haul <br />trucks were used to transport the Soil Liner Fill to the sediment pond. The Soil Liner Fill <br />stockpile from Arequa Process area was used which was augmented with bentonite (material <br />left over from Phase IV). The remaining Soil Liner Fill was hauled from the South Cresson <br />Clay Process stockpile. One CAT D-6 Dozer was used to spread the Soil Liner Fill in a 16" <br />loose lifts. No compaction efforts were performed during the week. AMEC observed the <br />placement of the Soil Liner Fill. An AMEC representative obtained two samples of the Soil <br />Liner Fill material. ' <br />E) Subgrade Preparation <br />1) VLF <br />No work performed during the week. <br />2) Sediment Collection Pond <br />Work on the remaining pond slopes was completed early in the week. <br />F) Material Processing <br />1) South Cresson Clay Process <br />Soil Liner Fill production for the VLF continued at the South Cresson Clay Process area. <br />Sheet 2 of 7 <br />VLF Weekly Report WE 05.09.09.D
