• <br />Leak Detection: <br />Approximately 720 lineal feet of leak detection trench was excavated down slope of stations <br />FF3 +00 to FF9 +00 in the Phase 1 VLF. About 520 feet of the trench was completed and covered <br />with SLF. A leak detection fill record sample was collected from this area. <br />B) Underground Workings: <br />No underground remediation or confirmatory drilling occurred during this reported period. <br />C) Geomembrane: <br />PSSA 100 -mil SSMS LLDPE Liner <br />100 -mil liner in the PSSA was exposed in various places along the backfilled anchor trench on <br />Bench A, the Highway 67 embankment, and SGVLF pad for repairs. <br />Phase 1 80 -mil DSMS LLDPE Liner Installation <br />Two rolls of 80 -mil DSMS geomembrane liner were deployed. Panels P115 through P123 were <br />installed totaling 11,011 square feet with 728 lineal feet of fusion welded seams and 216 lineal <br />feet of extrusion welded seams. ECA also extrude welded a piece of liner above the PSSA <br />shoulder for additional berm containment from Phase 1 slope into the PSSA. <br />Destructs DX -9 and DX -10, and DF-40 through DF -45 were cut and tested with passing results. <br />Approximately 235 lineal feet of anchor trench was backfilled over the installed liner. <br />Panels P1 through P123 were approved for drain cover fill placement. <br />D) Drain Cover Fill (DCF) <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 continued placing and finish - grading DCF on approved primary liner with Cat GPS dozers <br />on panels P17 to P22; P77 to P82; P90 to P91; P102 to P124; P141; P143 to P144; P146 to <br />P148; P151 to P152; P154 to P155; P221 to P227; P248 to P299; and P321 to P324. A Cat <br />excavator placed DCF material on the 28 -inch HVSCS piping that was placed on the floor of the <br />PSSA. <br />See the attached DCF map for all placement. <br />E) High Volume Solution Collection System Piping (HVSCS): <br />Fusion welding continued on the HVSCS 28 -inch HDPE piping in the PSSA floor and was <br />completed. <br />24- inch - diameter ADS and 28- inch - diameter HDPE piping was placed for tie -in at the north end of <br />the PSSA floor. <br />Approximately 800 feet of 28 -inch HDPE HVSCS piping was installed of the PSSA floor (400 feet <br />on the central piping and 400 feet on the eastern portion). The 28 -inch HDPE piping was placed <br />on primary geomembrane and as -built surveyed completing the 28 -inch HDPE piping. <br />II) Storm Water Management <br />Best Management Practices (BMPs) are being performed. <br />2014- 11 -08-MLE2 WEEKLY FINAL.DOCX Page 3 of 7 <br />
