ameO <br /> Geomembrane: <br /> PSSA <br /> Primary 100-mil DSMS LLDPE Liner Installation <br /> ECA installed 100-mil LLDPE smooth geomembrane grade at the west slope of PSSA from the <br /> ADR platform to the PSSA floor. Panels P-67 through P-87 were deployed on approved LVSCF. <br /> Sixteen full rolls and multiple partial rolls of 100-mil LLDPE smooth geomembrane were deployed <br /> yielding 4,466 lineal feet of fusion welds for an approximate installed weekly total of 114,480 <br /> square feet. Quality control was performed using one extrusion gun. All seams were fusion <br /> welded per project technical specifications. All work performed was observed by AMEC Quality <br /> Assurance (QA)personnel. <br /> Destructive samples PDF-21 through PDF-31were marked; destructive samples PDF-21 through <br /> PDF-26 were pulled and tested, all destructive samples that were tested passed per project <br /> technical specifications. <br /> Secondary 100-mil SSMS LLDPE Liner Installation <br /> A Cat mini excavator was used to excavate anchor trench at the north to northeast and northeast <br /> PSSA slopes. Anchor trench excavation met anchor trench project requirements. Depth anc <br /> width were verified during excavation. Anchor trench was subsequently backfilled and <br /> compacted with a maximum of 1-foot compacted depth above geomembrane that had been <br /> tested non-destructively. <br /> ECA continued installing 100-mil LLDPE SSMS geomembrane at the PSSA west and north <br /> slopes and the northern portion of the PSSA floor. Panels S-351 through S-360 were deployed <br /> during the week. Fifteen full rolls and multiple partial rolls of 100-mil LLDPE SSMS <br /> geomembrane were deployed yielding 7,484 lineal feet of fusion welds for an approximate <br /> installed weekly total of 139,888 square feet. Quality control was performed using up to two <br /> extrusion guns. All work performed was observed by AMEC Quality Assurance(QA) personnel <br /> and was completed in accordance with project technical specifications. <br /> Destructive samples DF-143 through DF-160 were marked; destructive samples DF-143 through <br /> DF-149, DF151, DF-152, DF-156, DF-157, DF-158 and DF-160 were tested and passed per <br /> project technical specifications. Destructive samples DF-153, DF-154, DF-155 and DF-159 were <br /> marked but not tested. Destructive sample DF-150 was tested and did not meet minimum project <br /> technical specifications. DF-150A and DF-150B were marked and will be tested after the <br /> destructive samples are removed from the geomembrane. <br /> C) Overliner: <br /> PSSA <br /> Cat 740 trucks hauled low volume solution collection fill (LVSCF) to the PSSA. Haul roads for the <br /> trucks were maintained at least 4 feet above secondary geomembrane. <br /> Ames continued placing LVSCF on approved secondary liner in minimum 3-foot lifts with Cat <br /> GPS D6 and D8 wide pad dozers between panels S-101 to S-108; S-120 to S-130; S-164 to S- <br /> 168; S-189 to S-198; S-205 to S-206; S-218 to S-219; S-244 to S-247; S-276 to S-278; S-282 to <br /> S-283; S-302 to S-311; S-312 to S-317; and S-339 to S-349. <br /> See the attached LVSCF map for all placement locations. <br /> 2014 08 30-M,LE2 WEEKLY FINAL Page 3 0'8 <br />
