ame& <br />E.-rSS *?nvircnrrrsiAa <br />approximately 300 to 375 feet left of centerline using three track mounted drill rigs. <br />Blasting was performed in these areas Thursday (12/17/2009) and Friday (12/18/2009). <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-8 <br />dozer, a CAT 320 excavator, and a CAT 966 front-end loader were used to process the material. <br />Location This Week <br />(tons) Cumulative <br />(tons) Comments <br />So Cresson Clay Processing 5,159 150,273 <br />Squaw Gulch Processing 0 35,816 Processing in area complete. <br />Total 5,159 182,181 <br />Soil liner fill processing totals not received from Ames for week ending 12/19/2009. <br />H) ADR and Crusher Waterlines <br />Hydrostatic testing of the 10" HDPE ADR waterline (station A24+00 (+/-) to the new ADR water <br />tank) was performed. The line was pressurized to 180 psi (1.5 x operating pressure) and held the <br />pressure for one hour. This meets the CEntry project specification. The testing was performed <br />under the observation of an AMEC field representative. <br />Construction of the ADR tank overflow line was finished. Trench excavation was performed using <br />a CAT 330 excavator. Pipe bedding placement was also performed as the trench excavation <br />progressed. This was performed using a CAT 966 front-end loader and a CAT 330 excavator. <br />Approximately 180 linear feet of trench was excavated and bedded. Approximately 180 linear feet <br />of 18-inch CPe was installed using a CAT 966 front-end loader for pipe delivery. The pipe was <br />coupled and backfilled using pipe bedding material. Pipe bedding material was compacted using a <br />CAT 330 excavator bucket. Approximately 180 linear feet of trench was backfilled. <br />Preparations for ADR waterline tie-ins were performed throughout the week. <br />I) Miscellaneous <br />No work performed during the week. <br />III) Underground Workings <br />A) Drilling <br />Confirmation drilling was finished at Underground workings #3006 and #3007. Twenty-two holes <br />were drilled on the northwest side of the workings, defining the limits of the loose material <br />previously encountered. A total of 1100 feet was drilled, encountering no voids. The drill holes <br />were surveyed by Ames' survey. The survey information will be sent to John Lupo and a <br />remediation plan will be submitted. <br />Confirmation drilling was finished at Underground working #3009. Five holes were drilled around <br />the center of the working and no voids were encountered. A total of 250 feet was drilled, <br />encountering no voids. The drill holes were surveyed by Ames' survey. The survey information <br />will be sent to John Lupo and a remediation plan will be submitted. <br />VLF Weekly Report WE 12.19.09.D.doc
