AMEC reviewed QC documents prior to geomembrane placement and verified the documentation was complete and the material properties and QC testing frequency required by the specifications were met. 5.2.1 Resin QC Certificates LLDPE polymer raw material (resin) QC certificates were provided by the resin manufacturer, Chevron Phillips Chemical Company, at a frequency of one per rail car shipment. AMEC reviewed these certificates prior to geomembrane placement. All geomembrane used on this project was produced from the same batch of resin. The geomembrane manufacturer also performed density and melt index tests of the resin supplied by Chevron Phillips Chemical Company to verify material properties prior to geomembrane manufacture. The QC certificates provided by the resin manufacturer are presented in Appendix 1.3. 5.2.2 Roll QC Certificates ECA provided QC certificates for each roll (approximately every 8,855 square feet) of LLDPE geomembrane used for the project, exceeding the required minimum frequency of one per 50,000 square feet of geomembrane.
