Cripple Creek & Victor Gold Mining Company <br />Laboratory Liner Extension <br />Final Report ameO <br />Quality Assurance Monitoring &Test Results <br />January 14, 2014 <br />5.0 GEOSYNTHETIC CQA TESTING AND MONITORING <br />The following sections describe the CQA activities performed by AMEC for the <br />geomembrane installed in the certified areas. <br />In accordance with the AMEC CQA Plan, when an AMEC monitor observed <br />deficiencies, the monitor determined the nature and extent of the problem and notified <br />Lone Star and /or CC &V representatives. When unsatisfactory test results identified a <br />deficiency, AMEC performed additional tests to define the extent of the area. Lone <br />Star corrected deficiencies to meet the requirements of the specifications, and AMEC <br />re- tested and approved the corrected deficiency prior to any additional related work. <br />The following sections include discussions of the deficiencies encountered. <br />5.1 Geosynthetic Clay Liner (GCL) <br />CQA activities conducted by AMEC during the installation of the BentoLiner NWL GCL <br />consisted of the following: <br />• Observation and approval of the subgrade prior to deployment of GCL. <br />• Observation and documentation of GCL deployment, including verifying damage <br />did not occur, sufficient overlap was achieved, and documenting panel layout. <br />• Observation and documentation of field seaming; <br />• Observation and documentation of GCL repairs. <br />• Observation and documentation of installation in accordance with manufacture's <br />recommendations. <br />5.2 Geomembrane <br />CQA activities conducted by AMEC during the installation of the LLDPE geomembrane <br />consisted of the following: <br />• Conformance sampling and testing of the geomembrane <br />• Observation and approval of the GCL surface prior to deployment of geomembrane <br />• Observation and documentation of geomembrane deployment, including verifying <br />sheet thickness and overlap, and documenting panel layout <br />• Observation of trial seam sample testing and documentation of results <br />• Observation and documentation of field seaming <br />• Identification of destructive seam sample test locations, observation of destructive <br />seam sample testing, and documentation of test results <br />• Observation and documentation of geomembrane repairs <br />s1projects \1125m -cc &v lab liner extension\h2 - design \lab liner extension \roc report\lab liner roc report.docx <br />s <br />
