ame0 <br />AMEC and Lone Star verified that the SLF surface had been proof - rolled, and that the SLF <br />surface was free of desiccation cracks. Where the surface of the SLF did not meet <br />specifications, Ames repaired the area and re- compacted the surface. Lone Star provided <br />written certification of geomembrane subgrade acceptance. The subgrade acceptance <br />certificates are presented in Appendix G. <br />AMEC assigned each geomembrane panel a number. Single -sided textured 80 -mil LLDPE <br />geomembrane (textured side down) panels deployed in the Process Solution Enhancement <br />System were designated by P1 through P81 as part of the primary liner. <br />AMEC marked the panel designation and roll number directly on each panel after it was <br />deployed. The geomembrane record drawing, showing the Process Solution Enhancement <br />System primary geomembrane panel layout and destructive testing, is presented as Record <br />Drawing No. 3 of 4 in Appendix A. <br />During geomembrane deployment, AMEC measured sheet thickness with a pointed <br />micrometer. AMEC measured sheet thickness at five random locations along each edge of <br />each geomembrane panel. The average thickness specified for the 80 -mil geomembrane <br />was 80 mils. Project specifications for 80 -mil geomembrane required that the average of the <br />five thickness measurements be no less than the 80 mils, and that no individual <br />measurement be less than the nominal thickness minus 8 mils (i.e., 72- mils). The thickness <br />monitoring provided by AMEC indicated that all of the panels met or exceeded project <br />requirements. <br />AMEC personnel measured deployed panel lengths by use of a measuring wheel. <br />Recorded lengths were approximate, and do not reflect any trimming or adjustments made <br />for final placement or anchor trench lengths. <br />AMEC personnel observed the surface of each deployed panel. AMEC logged any <br />penetration defects and marked them on the panel. Section 6.4 provides further discussion <br />of repairs. AMEC also observed the overlap of each panel with adjacent panels to verify <br />AMEC Environment & Infrastructure, Inc <br />2000 S.
