A minimum of 88 SLF nuclear density/moisture tests were required, and a total <br />of 102 SLF nuclear density/moisture tests were performed with passing results. The depth <br />check frequency is twice per acre of finished SLF. A minimum of 41 SLF depth checks were <br />required. A total of 102 SLF depth checks were performed with passing results. SLF <br />nuclear density/moisture testing and SLF depth checks are presented in Tables 7 and 8, <br />respectively. <br />3.2.3. Drain Cover Fill <br />VLF2 Phase 3 Stage A.2 was constructed by placing 87,890 cy of crushed ore drain cover <br />fill (DCFO). No non-ore DCF was used for this construction. The particle size distribution <br />and Atterberg limits testing frequencies were one sample for every 20,000 cy. A minimum <br />of 5 DCFO samples were required to be tested for particle size and Atterberg limits. A total <br />of 11 DCFO samples were tested with passing results. DCFO laboratory testing is <br />summarized in Table 6, and individual test results are presented in Appendix G.3 <br />3.3. Geosynthetics Quality Control Submittals <br />The NewFields CQA reviewed and approved all geosynthetic QC submittals, including <br />geomembrane installation personnel resumes, geomembrane roll QC certificates, geomembrane <br />resin QC certificates, welding rod QC certificates, and geotextile QC certificates. The NewFields <br />CQA tracked all geomembrane delivered to site. The inventories of all 80-mil geomembrane at <br />the site are provided in Appendix H.2. <br />3.3.1. Geomembrane Installation Personnel Resumes <br />ECA submitted the resumes of relevant installation personnel prior to construction or <br />repair activities within the VLF2 Phase 3 Stage B.1 area. The CQA Monitor verified that <br />the Installation Superintendent, Master Seamer and QC Inspector met the installation <br />experience required by the project Technical Specifications. Geomembrane installation <br />personnel resumes for crews that performed work on the VLF2 Phase 3 Stage B.1 area are <br />presented in Appendix H.1. <br />3.3.2. Geomembrane Roll QC Certificates <br />The VLF2 Phase 3 Stage B.1 geomembrane was manufactured by AGRU America. <br />Manufacturing Roll QC certificates were submitted for every roll of geomembrane <br />(approximately one every 9,430 square feet), exceeding the required minimum frequency <br />of one per 50,000 square feet of geomembrane. The roll QC certificates were reviewed <br />by the CQA Monitor, ensuring all geomembrane materials met or exceeded the Technical <br />Specifications requirements. It should be noted that a separate Asperity test measuring <br />the height of the microspikes on the liner was also recorded in the QC certificates. The <br />Asperity height is separate from the thickness of the liner. All QC certificates for 80-mil, <br />for VLF2 Phase 3 Stage B.1 are provided in Appendix H.3.
