J 0 5.3.3 Defects and Repair 5.3.3.1 Identification The Ausenco Vector CQA monitor checked seams and non -seam areas of the geomembrane for any defects, holes, blisters, undispersed raw materials, and for signs of contamination by foreign matter. Suspect areas were distinctively marked for repair, with a description of the required type of repair and the repair location recorded in the Repair Logs. No additional materials were placed over the geomembrane until the Ausenco Vector CQA monitor approved the repair. 5.3.3.2 Repair Procedures and Testing The repairs were conducted in accordance with the applicable method specified within the project specifications. The Ausenco Vector CQA monitor reviewed each repair and verified that subsequent testing was performed. These Repair Logs are presented in Appendix I. 5.3.4 Leak Location Survey A leak location survey was conducted twice during the construction of WMU FU -10. The first leak location survey was performed on the exposed 60 -mil HDPE geomembrane deployed on the floor of FU -10, prior to the placement of the cushion geotextile. The second leak location survey was performed on the floor of FU -10 upon completion of the Operations Layer soils placement. Ausenco Vector engineers conducting the leak tests found no holes during either of the leak tests. A complete report of the leak testing procedure and findings of the leak location surveys are included in Appendix J. 5.4 Geotextile 5.4.1 General A 12 oz/yd2 Cushion geotextile was used on the floor between the HDPE geomembrane and LCRS Granular Drainage (GD) material. A 7oz/yd2 Filter geotextile was used as a separation layer (filter) between the LCRS Granular Drainage material (GD) and the Operations Layer soils. It was also used in the LCRS trenches to encapsulate the Coarse Gravel (CG) and perforated HDPE piping. 5.4.2 Receiving Inspection Upon arrival by truck, the Ausenco Vector CQA monitor observed the unloading and storage of each roll of geotextile. Each roll of geotextile was recorded in the Receiving Logs by roll number and crosschecked against the manufacturers quality control documents (MQC Certificates) provided by the manufacturer. Following inspection of the rolls and review of the MQC Certificates the material was approved for deployment. A copy of the Geotextile Receiving Logs and the manufacturers quality control data (MQC Certificates) are included in Appendix K. During deployment of the 7 oz/yd2 filter geotextile on the deck area above the 5:1 slope the installer ran out of material. Forward Landfill was able to purchase additional material from a local supplier. The Ausenco Vector CQA monitor collected a sample from one of the new rolls (roll number 140025179) for conformance testing. These test results can be found in Appendix I. 5.4.3 CQA Conformance Testing Select samples of the geotextile were cut from random rolls at the manufacturing plant by the third party testing laboratory, TRI, for conformance testing in accordance with the project specifications and CQA manual. Conformance testing included: 0 • mass per unit area (ASTM D-5261); and Date: October 2010 USVC0004800 Final Construction Quality Assurance Report 22
