ANA <br />0" <br />ame <br />Earth & Environmental <br />G) Material Processing <br />1) East Cresson Clay Borrow Area <br />Mobilization and set up of the soil liner fill processing plant was completed this week. <br />Processing of Soil Liner Fill material began this week. A CAT D-8 dozer, a CAT 320 excavator, a <br />CAT 966 front-end loader, and tandem-axel haul trucks were used to excavate, haul, and process <br />the material.

The area was excavated down to 25 feet below finish grade and no <br />working or voids were encountered. John Lupo, P.E. Project Sponsor, stated that there is no <br />historic evidence of a working in the area. The excavated area will be backfilled as structural fill <br />placement progresses, through this area. No additional remediation is required for this working. <br />Confirmatory drilling was performed for Underground Working #3012. A drill pattern was set out <br />by an AMEC field representative. Fourteen holes were drilled encountering three voids. An <br />approximate total of 700 feet was drilled. An AMEC representative observed the confirmatory <br />drilling constantly. It will be necessary to remediate the lower portion of the working before any <br />further drilling can be performed to the east. Temporary fill material will need to be placed over <br />the working to gain access to the east side of the working. The crown pillar will be collapsed by <br />blasting and excavated. The working will then be remediated per plan. Prior to any remediation all <br />Temporary fill will be removed <br />Confirmatory drilling was performed for Underground Working #3013. A drill pattern was set out <br />by an AMEC field representative. Thirty-five holes were drilled encountering no voids. An <br />VLF Weekly Report WE 02.13.10.D.doc
