T A MOO <br />The temporary drain located near the south toe berm was removed to allow for LVSCF placement <br />in the area. The HDPE pipe was cut approximately 6- inches below the bottom of SLF. The pipe <br />was then plugged with concrete approximately 4 -feet in length and the end capped with concrete. <br />SLF material was then placed over the concrete plugged pipe repairing the subgrade to allow for <br />the geomembrane in the area to be repaired. <br />III) Material Processing <br />A) Drain Cover Fill Process Area <br />No Drain Cover Fill (DCF) was processed during the week. <br />Location <br />This Week <br />Cumulative <br />Comments <br />(tons) <br />(tons) <br />DCF Process <br />0 <br />121,223 <br />Total <br />0 <br />121,223 <br />IV)VLF Geosynthetics <br />A) Geomembrane Installation <br />1) VLF <br />Geomembrane installation within the Phase 5 VLF continued performing deployment, <br />seaming, and repair /QC activities. Geomembrane installation was performed in the area shown <br />in Figure 3. Approximately 157,439 square feet of secondary 100mi1 LLDPE was deployed <br />using a John Deere 200 excavator and a John Deere 544 front -end loader with spreader -bar <br />attachments. Subgrade was inspected and approved by AMEC and Lone Star representatives <br />prior to geomembrane deployment (see Figure 3). Approximately 9,257 linear feet of seam was <br />fusion welded using four fusion welding machines. Nineteen destructive test samples were <br />marked during fusion seaming. All destructive tests performed were within project <br />specifications. Non - destructive testing was performed for fusion welded seams. Repairs were <br />performed using the extrusion welding method for all marked defects. Vacuum testing was <br />performed for all extrusion welded seams and repairs. <br />B) Anchor Trench <br />1) VLF <br />PSSA anchor trench excavation continued between stations K4 +00 ( + / -) and E5 +00 ( + / -) using <br />a CAT 312 excavator and one laborer. The anchor trench was inspected by an AMEC field <br />representative and found to be constructed in accordance with design drawings and project <br />specifications. <br />C) Geomembrane Acceptance <br />1) VLF <br />Secondary 100mil geomembrane (S -613 thru S -614, S -622 thru S -631, S -700 thru S -717, S- <br />749 thru S -815) shown on Figure 4a and 4b was inspected by AMEC and Lonestar <br />representatives and found to be installed within project specifications and acceptable for <br />continued construction activities. <br />VLF Weekly Report WE 09.04.10.D <br />
