ameO <br /> material was produced. The soil liner fill processing equipment is being transferred back to the <br /> Cameron site. <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 /> Excavation at underground workings#6628 and#6629 began. Additional remediation is <br /> required. <br /> Underground workings#6561 and#6606 were excavated but competent rock was not reached. <br /> Drill access was provided and confirmatory drilling began. Confirmatory drilling was completed <br /> on#6561, drilling on#6606 continues. <br /> Underground workings#6119 and#6260 were blasted. Additional remediation is required for <br /> underground working#6119. <br /> Underground workings#6260,#6625, #6627,#6607 were excavated to competent rock, <br /> backfilled according to project specifications, and are considered remediated. <br /> C) Geomembrane: <br /> • PSSA <br /> Geomembrane installation within the PSSA began this week performing deployment, seaming, <br /> repair, and QA/QC activities. Geomembrane installation was performed at the ADR pad and <br /> PSSA northwest slope. Approximately 125,995 square feet of 100mil LLDPE geomembrane was <br /> deployed. Subgrade was inspected and approved by AMEC, Ames and ECA representatives <br /> prior to geomembrane deployment. Approximately 6,257 linear feet of seam was fusion welded <br /> during deployment using one or two fusion welding machines for each day of deployment. <br /> 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 /> Panels S2 through S11 (secondary 100mil LLDPE—58,503 sq.ft.)were inspected and accepted <br /> by AMEC, Ames and ECA representatives. <br /> II) Storm Water Management <br /> Best Management Practices (BMPs)are being performed. <br /> 2014.06.14-mle2 weekly final Page 3 of 7 <br />
