ameO <br />Earth k EnvfnxsnwntM <br />3. Sediment Collection Pond <br />Work has been completed <br />D. Cut to Fill <br />1. VLF <br />Suitable structural fill material during the week from the LOB Delivery Road cut from <br />between stations 23+50 (+/-) to 24+50 (+/-), 32+50 (+/-) to 31+50 (+/-) and 2+00 (+/-) <br />to 4+00 (+/-) was hauled to the VLF using all haulage equipment (CAT 777 and Volvo <br />A40D). The structural fill material was placed and compacted between stations L2+00 <br />(+/-) to L8+00 (+/-) approximately 75 to 125-feet left of centerline. One Cat D-8 dozer <br />was spreading and benching the fill. Compaction was achieved using a vibratory <br />smooth drum compactor. Ambient and fill temperatures were monitored during fill <br />placement. No frozen materials were placed. <br />Suitable structural fill material during the week from the LOB Delivery Road cut from <br />between stations 29+00 (+/-) to 28+50 (+/-) and 19+50 (+/-) to 21+50 (+/-) was hauled <br />to the VLF using all haulage equipment (CAT 777 and Volvo A40D). The structural fill <br />material was placed and compacted between stations B 10+00 (+/-) to B 14+00 (+/-) at <br />or near centerline to 100-feet right of centerline. One Cat D-8 dozer was used to spread <br />the structural fill material. Compaction was achieved using a vibratory smooth drum <br />compactor. Ambient and fill temperatures were monitored during fill placement. No <br />frozen materials were placed. <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 />E. Subgrade Preparation <br />1. VLF <br />Subgrade preparation was performed between stations L2+00 (+/-) to L8+00 (+/-) <br />(future Plant Access Route) approximately 75 to 125-feet left of centerline. A Cat D- <br />10 dozer with a single shank ripper shank was used. <br />2. Sediment Collection Pond <br />Suitable structural fill from the LOB Delivery road cut was hauled intermittently to the <br />sediment pond for completion of the pond floor to design subgrade elevation. The fill <br />was spread in loose lifts with a Cat D-6 dozer and compacted-using a vibratory smooth <br />drum compactor. <br />F. SLF Processing (Material is being generated/processed for the VLF) <br />Clay production was completed at the Squaw Gulch Clay Process Dump 5 on Wednesday. <br />The clay plant was moved to the South Cresson Clay Processing. Start-up is scheduled for <br />Monday. <br />The material screening plant located at the AGOSA (Arequa Gulch Overburden Storage <br />Area) processed materials for the LOB. The plant ran intermittently throughout the week. <br />Sheet 2 of 6 <br />VLF Weekly Report WE 04.25.09.D.doc
