Approximately 386,363 square feet of 80mil LLDPE geomembrane <br />was deployed. Soil Liner Fill was inspected and approved by AMEC, Ames and ECA <br />representatives prior to geomembrane deployment. Approximately 17,357 linear feet of seam <br />was fusion welded during deployment using one or two fusion welding machines for each day of <br />deployment. Approximately 1,021 linear feet of seam was extrusion welded during deployment. <br />Destructive and non-destructive testing was completed in compliance with project 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 per project specifications. <br />See attached figure for approved geomembrane. <br />II) Storm Water Management <br />Best Management Practices (BMPs) continued to be performed. <br />
