ame. <br />Earth & Environmental <br />G) 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 />8 dozer, a CAT 320 excavator, and a CAT 966 front -end loader were used to process the <br />material. <br />Location <br />Week <br />tons <br />Cumulative <br />Comments <br />So Cresson Clay Processing <br />3,588 <br />130,947 <br />Squaw Gulch Processing <br />0 <br />35,816 <br />Processing in area complete. <br />Total <br />3,588 <br />166,763 <br />H) ADR/Crushing Waterline Construction <br />Continue excavating the ADR waterline between Stations A0 +00 ( + / -) and A3 +00 ( + / -). One CAT <br />345 excavator and one CAT 330 excavator equipped with a "rock breaker" were used for the <br />trenching activities. Placed protective wrap on the 10 and 12 -inch steel pipe welds. <br />I) Toe Berm Primary Underdrain <br />Placed approximately 300 -feet of primary underdrain 6 -inch diameter CPe pipe. Pipe was encased <br />in Geofabric and drain rock per Drawing A260 <br />III) Underground Workings <br />A) Drilling <br />No work performed during the week. <br />B) Mine Shaft /Stope Remediation <br />Underground working 3008, Thompson Shaft: Completed structural fill and site grading for <br />Geogrid placement per AMEC Memo, dated 10 November 2009. and per Drawing A290. Select <br />structural fill was placed over each layer of Geogrid. Compaction was achieved using a 10 -ton <br />vibratory smooth drum compactor passing over the entire surface a minimum of 5 passes. Nuclear <br />density testing was performed with results averaging 95% of maximum dry density. Moisture <br />density relations were obtained in accordance with ASTM D698 -07. AMEC provided full -time <br />observation during the remediation <br />C) Lateral/Slot Remediation <br />No work performed during the week. <br />IV) Storm Water Management Structures <br />A) Control Structures <br />No work performed during the week. <br />B) Best Management Practices <br />Best Management Practices are being observed throughout the VLF Phase 5 Project. Storm water <br />controls were maintained throughout the week. <br />VLF Weekly Report WE 11.21.09.D.doc <br />
