Aft <br />Cameron Site for future use. The soil liner fill processing equipment remains at the Cameron site. <br />No new processing during this reporting period. <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 />Underground working #6631 was blasted. Additional remediation is required. <br />Confirmatory drilling of underground working #6579 was completed. Additional remediation is <br />required. <br />Confirmatory drilling of underground working #6318 began and is still in progress. <br />Coarse shaft backfill of underground working #,f6446 continued. Additional remediation is <br />required. <br />Completed geogrid placement at underground working 46119. Site remediated. <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, PSSA closure drain slopes and PSSA west slope. Approximately 140,300 square feet of <br />100mil LLDPE geomembrane was deployed. Subgrade was inspected and approved by AMEC, <br />Ames and ECA representatives prior to geomembrane deployment. Approximately 7,441 linear <br />feet of seam was fusion welded during deployment using one or two fusion welding machines for <br />each day of deployment. Destructive and non- destructive testing was completed per technical <br />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 -1, S131 thru S -145, S -164 thru S -182, S -185, S -194 and S- <br />195(secondary 100mil LLDPE — 195,483 ft2) were accepted and approved for low volume <br />placement by AMEC, Ames and ECA representatives during this reporting period. Additional <br />repairs may be required prior to placement of low volume solution collection fill (ie. wrinkle <br />removal, sub -liner rock repair). <br />II) Storm Water Management <br />Best Management Practices (BMPs) are being performed. <br />2014.07.05 -mle2 weekly final Page 3 of 7 <br />
