amen <br />Earth 8 Environmental <br />Structural fill was placed between stations K5+00 (+/-) and K9+00 (+/-), approximately 75 to <br />100 feet left of centerline. Structural fill was placed using CAT dozers in 18" to 24" lifts <br />(based on rock size). Moisture conditioning of the fill was performed using a CAT 773-water <br />truck. Each lift was compacted with a CAT 563 smooth drum vibratory compactor passing <br />over the entire surface at least 4 times (method compaction technique is applicable). <br />Slope scaling was performed at the A-line cut area using a CAT 345 excavator. <br />Blast pattern drilling was performed between stations A10+00 (+/-) and A11+50 (+/-), <br />approximately 0 to 30 feet left of centerline using two track mounted drill rigs. <br />F) Material Processing <br />1) South Cresson Clay Processing Area <br />Processing of Soil Liner Fill material continued at the South Cresson Clay Process. A CAT D- <br />6 dozer, a CAT 320 excavator, and a CAT 966 front-end loader were used to process the <br />material. <br />Location hi s)Week Coumulative Comments <br />So Cresson Clay Processing 4,211 36,985 <br /> <br />Squaw Gulch Processing <br />- <br />35,816 Processin in area com lete. <br />Total 0 68,180 <br />G) Miscellaneous <br />Installation of the LOB Storm Water Culverts was completed using a CAT 345 excavator, a <br />jumping jack compactor, and a walk-behind sheep's foot compactor. Sixty-four feet of 42" CMP <br />culvert was installed for both culverts. A CAT 345 track excavator was used to excavate a trench <br />for the culvert installation and 6" of pipe bedding material was placed in the trench bottom. The <br />pipe bedding material was moisture conditioned and compacted using a walk-behind sheep's foot <br />compactor. Pipe bedding material was used to backfill each side and between the culverts in 12" <br />compacted lifts, bringing the backfill up evenly. The material was moisture conditioned and <br />compacted using a jumping jack compactor and a walk behind sheep's foot compactor. The area <br />was backfilled to two-feet above to installed culverts. Eleven nuclear density tests were performed <br />using with results averaging 96% of maximum dry density. Moisture-density relations were <br />performed in accordance with ASTM D-698-07. Riprap was placed at the inlet of the culvert <br />installation. <br />III) Underground Working <br />A) Drilling <br />No work performed during the week. <br />B) Mine Shaft/Stope Remediation <br />No work performed during the week. <br />C) Lateral/Slot Remediation <br />No work performed during the week. <br />Sheet 3 of 7 <br />VLF Weekly Report WE 06.27.09.D.doc
