amele <br /> Underdrain System: <br /> Primary Underdrain: Complete. <br /> Secondary Underdrain: No work was performed on the secondary underdrain. <br /> Tertiary Underdrain: Complete in PSSA footprint. <br /> B) Underground Workings <br /> Confirmatory drilling of underground workings#6606 and#6631 was completed. Additional <br /> remediation is required. <br /> Excavation at underground workings#6446 began. Additional remediation is required. <br /> Underground workings#6628, #6629,#6630 were excavated to competent rock; backfilled <br /> according to project specifications, and are considered remediated. <br /> Preparation of the subgrade for geogrid installation began on underground working#6119. <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 at the ADR <br /> pad and PSSA northwest slope. Approximately 227,496 square feet of 100mil LLDPE <br /> geomembrane was deployed. Subgrade was inspected and approved by AMEC, Ames and ECA <br /> representatives prior to geomembrane deployment. Approximately 11,744 linear feet of seam <br /> was fusion welded during deployment using one or two fusion welding machines for each day of <br /> deployment. Destructive 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 /> No additional panels(secondary 100mil LLDPE)were accepted by AMEC, Ames and ECA <br /> representatives during this reporting period. <br /> II) Storm Water Management <br /> Best Management Practices (BMPs) are being performed. <br /> 2014.06.21-mle2 weekly final Page 3 of 7 <br />
