October 2004 -30- 043 -2170 <br />surface of the SL>~ appeared rough, Ames provided repair and re- compaction over the affected area. <br />• Poly -Flex provided written certification of geomembrane subgrade acceptance. The subgrade <br />acceptance certificates are presented in Appendix G. <br />Golder assigned each geomembrane panel a consecutive number. Single -sided textured 80 -mil <br />geomembrane panels deployed in the OSA were designated by C -1 through C -811. Golder marked <br />the panel designation and roll number directly on each panel after it was deployed. The <br />geomembrane record drawing, showing the geomembrane panel layout and destructive testing, is <br />presented in Record Drawing No. 5 (Appendix A). <br />During geomembrane deployment, Golder measured sheet thickness with a micrometer. Golder <br />measured sheet thickness at five random locations along one edge of each geomembrane panel. The <br />average thickness specified for the 80 -mil geomembrane was 80 -mil. For the 80 -mil geomembrane, <br />project specifications required that the average of the five thickness measurements be no less than the <br />80 -mil and that no individual measurement be less than nominal thickness minus 8 -mil (i.e., 72 mil). <br />The thickness monitoring provided by Golder indicated that all of the panels met or exceeded project <br />requirements. <br />Golder personnel measured deployed panel length using a measuring wheel. Recorded lengths were <br />approximate, and may not reflect any trimming or adjustments made for final placement or anchor <br />trench lengths. <br />Golder personnel observed the surface of each deployed panel. Golder logged any penetration defects <br />and marked them on the panel. Section 6.1.4 provides further discussion of repairs. Golder also <br />observed the overlap of each panel with adjacent panels to verify that sufficient overlap for seaming <br />existed. Golder logged insufficient panel overlaps as defects and marked them for correction. <br />Ames surveyed all panel intersections and destructive seam sample locations. Using these points, <br />Golder has provided the panel layout record drawing (Record Drawing No. 5), in Appendix A. <br />The LLDPE geomembrane deployment observations are presented in Appendix K -2. <br />e% am70% MMCert-Qnee rvo-1004104nl7&040&124Mcenftrvwoc Golder Associates <br />
