The LLDPE geomembrane was manufactured by Poly -Flex of Grand <br />Prairie, Texas. Geomembrane installation activities for the LOB liner system included <br />deployment, seaming, and non - destructive and destructive testing of 100 -mil single sided <br />texture and 80 -mil smooth LLDPE geomembrane. <br />Lonestar installed approximately 30,277 square feet of geomembrane, including geomembrane <br />in the anchor trench and overlap. A construction blast in the LOB road cut above the LOB pad <br />on April 23, 2009 caused damage to several liner panels. The majority of panels 1 through 8, <br />10 and 11 were replaced. All of panels 14 through 21 were replaced. The removal and <br />placement of the new panels was completed between April 26 and April 28, 2009. <br />Approximately 5,934 square feet of the original geomembrane was undamaged and not <br />replaced. <br />Geomembrane was placed on compacted and approved SLF. Ames anchored geomembrane at <br />the limits of the LOB in an anchor trench a minimum of 3 feet deep by 2 feet wide. The <br />geomembrane tie -in panels overlapped the Phase IVc geomembrane panels a minimum of <br />3 feet and were extrusion welded, as shown in Detail 3 of IFC Drawing A250. <br />SAPROJECTS \1125E CCV CQA \H3 - CONSTRUCTION \LOB CERT REPORT\REPORT BODY\LOB CERT REPORT 2009.07.01.DOC 9 <br />
