El consider site operating conditions when evaluating whether the theoretical performance of the system is likely to be achieved in reality. 6.1 Operations History While it is difficult to quantify an operational component to liner system performance, a site's operating history does offer a window into the likelihood of success. In this regard, it is noted that the existing Forward Landfill and Transfer Station/Resource Recovery Facility is operated under eighteen separate permits issued by the various agencies having jurisdiction over the facility. The fact that the RWQCB has issued no enforcement actions against the site over the last several years speaks to the superior operational, compliance and communications protocols included in routine site operations as well as the strong and cooperative relationship that has been established with RWQCB staff. In addition, the fact that RWQCB staff have publicly stated that, in their opinion, Forward is one of the best landfill operations in the region provides further validation of an operation that is likely to yield a single composite liner system that approaches its optimal performance. Some of the site operational elements that are more critical to ultimate liner system performance are discussed below. 6.2 Proposed Construction Quality Assurance (CQA) Protocols While it is widely recognized that the geosynthetic manufacturing process has improved dramatically over the years, construction and post -construction defects are recognized as a risk equal to or greater than manufacturing. In order to minimize the potential for the introduction of construction and post -construction related defects, all construction and/or site operations that occur on or within two feet of the Forward FML liner will be performed following strict specifications and will be completed only under the oversight of a qualified CQA inspector. The single composite liner system project plans and specifications proposed for the Forward Landfill expansion will be developed in accordance with the site JTD. Compliance with these plans and specifications will be monitored throughout the course of construction by third party Construction Quality Assurance (CQA) professionals who will follow a strict protocol established in the Project Construction Quality Assurance Plan. The CQA Plan will provide definition of the materials and procedures to be used in the construction of the lined refuse cells and assures the regulatory agencies that the construction materials will be tested, installed and monitored as specified and that accepted civil engineering practices and applicable CQA requirements of the RWQCB, CIWMB, and LEA will be satisfied. The CQA Plan will conform to all of the requirements specified in 27 CCR, Section 20324 and will specify the minimum experience requirements for contractors, work crews, and inspectors. Recognizing that one of the most significant construction risks is folding of the FML as the LCRS gravel and/or operations layers are deployed, the CQA program for the Forward single C1 MM-04l\17orwerd Composite Uner V3 .doe\09/19102 f' Geologic Associates
