"Wil M' <br />B) Underground Workings: <br />No underground remediation or confirmatory drilling occurred during this reported period. <br />C) Geomembrane: <br />Phase 1 80 -mil DSMS LLDPE Liner Installation <br />80 -mil liner installation is suspended at this time due to inclement weather. Refer to the figure in <br />the MLE2 weekly report for November 8, 2014 for accepted geomembrane in the Phase 1 area. <br />D) Drain Cover Fill (DCF) <br />Note: AMEC performed continuous monitoring of DCF fill temperatures in the stockpile as well as <br />the fill during placement. <br />Cat 740 trucks hauled drain cover fill to the PSSA. Haul roads for the Cat 740s were maintained <br />at least 4 feet above the secondary geomembrane and HVSCS piping. <br />Ames completed covering accepted liner with drain cover fill within the PSSA. <br />Drain cover fill was pushed down to the vertical riser pipe area from SGLFV haul road stations <br />8 +00 to 0 +00. Ames used the material to backfilled over the 6 -inch HVSCS PCPE piping that <br />was placed around the vertical riser sections at the 9,352 elevation. <br />Drain cover fill placement began in the Phase 1 area on accepted 80 -mil liner along Bench B. <br />The drain cover fill was placed according to project specifications. <br />See the attached DCF map for all placement within the PSSA and Phase 1 area. <br />E) High Volume Solution Collection System Piping ( HVSCS): <br />Six - inch - diameter PCPE HVSCS piping, 6 -inch 90- degree elbows, and perforated end caps, were <br />installed at the 9,352 elevation around the vertical riser piping and backfilled in the PSSA per <br />project specifications. <br />Ames placed 4 -inch and 12 -inch ADS HVSCS piping on approved liner in the Phase 1 area. <br />II) Storm Water Management <br />Best Management Practices (BMPs) are being performed. <br />2014 -11 -15 -MLE2 WEEKLY FINAL Page 3 of 7 <br />
