B) Underground Workings <br />Confirmatory drilling of underground working #6318 was completed and blasted. Excavation of <br />shot rock began. Additional remediation is required. <br />Underground working #6579 was blasted. Additional remediation is required. <br />C) Geomembrane_ <br />PSSA <br />Geomembrane installation within the PSSA continued this week performing deployment, <br />seaming, repair, and QA/QC activities. Geomembrane installation was performed on the east <br />slope. Approximately 82,643 square feet of 100 -mil LLDPE geomembrane was deployed. <br />Subgrade was inspected and approved by AMEC, Ames and ECA representatives prior to <br />geomembrane deployment. Approximately 3,712 linear feet of seam was fusion welded during <br />deployment using one or two fusion welding machines for each day of deployment. Destructive <br />and non - destructive testing was completed per technical specifications. <br />Ames continuously excavated anchor trench ahead of geomembrane installation. After <br />geomembrane testing was completed, the anchor trench above finished panels was backfilled <br />and compacted to project specifications. <br />Secondary liner panels S -183, S -184, S -200 through S -204 (100 -mil LLDPE — 14,145 ft2) were <br />accepted and approved for low volume placement by AMEC, Ames and ECA representatives <br />during this reporting period. Additional repairs may be required prior to placement of low volume <br />solution collection fill (ie. wrinkle removal, sub -liner rock repair). <br />D) Overliner: <br />• PSSA <br />Ames continued placing low volume solution collection fill (LVSCF) on approved secondary liner <br />in minimum 3 -foot lifts between panels S1 and S11, S40 to S42, S61 to S70 and S152 to S155 <br />upslope with a Cat D6 GPS dozer and a Cat D8 dozer. <br />II) Storm Water Management <br />Best Management Practices (BMPs) are being performed. <br />2014.07.12 -m1e2 weekly frnal Page 3 of 7 <br />
