1 INTRODUCTION <br /> 1.1 Purpose <br /> This Construction Quality Assurance(CQA)Manual has been prepared for Forward,Inc.(Forward) <br /> by a Registered Civil Engineer in accordance with Title 27,California Code of Regulations(CCR), <br /> Division 2, Sections 20323 and 20324, titled "CQA Plan and CQA Requirements." This manual <br /> describes CQA procedures for construction of the liner and leachate collection and removal system <br /> (LCRS)for Waste Management Unit FU-03 (WMU FU-03). The CQA Manual outlines the specific <br /> field and laboratory testing and monitoring procedures required to demonstrate that WMU FU-03 is <br /> constructed in accordance with Title 27 requirements. <br /> Following the completion of the work,the Quality Assurance/Quality Control(QA/QC)Consultant <br /> will prepare a final CQA Report. The CQA Report shall be submitted to the Owner within 20 days <br /> of construction completion. The purpose of the CQA Report is to document that the materials and <br /> construction processes comply with the WMU FU-03 design and regulatory requirements. As-built <br /> drawings and a discussion on the refuse fill stability of WMU FU-03 based on the actual interface <br /> shear strength test results obtained during the CQA testing program shall also be included. <br /> 1.2 Project Description <br /> Lewis Engineering was contracted by Forward to design WMU FU-03 in accordance with Forward's <br /> Waste Discharge Requirements (WDR Order No. R5-2003-0049), as well as applicable state and <br /> federal regulations. The provisions of particular importance regarding the design are: <br /> • The WMU FU-03 lining and leachate collection and removal system (LCRS) design <br /> shall conform to construction standards of Title 27 by using a composite liner and <br /> blanket LCRS. <br /> • WMU FU-03 will be designed, operated, and maintained to prevent inundation, <br /> washout, erosion, and slope failure resulting from flooding caused by a 24-hour storm <br /> with a 1,000-year return period. <br /> • WMU FU-03 will be designed to withstand the Maximum Credible Earthquake <br /> (MCE) without damaging the lining, leachate, or surface drainage control systems. <br /> • Leak location testing will be performed on the geomembrane following placement of the <br /> operations layer <br /> WMU FU-03 will be constructed in the former Austin Road Landfill Borrow Pit and Expansion <br /> Area, directly south of the Former Austin Road Landfill and on the western side (see Design and <br /> Construction Documents, Waste Management Unit FU-03, Forward Landfill, Lewis Engineering, <br /> 2002).The base liner will encompass approximately 6 acres and will extend approximately 650 feet <br /> in the north-south dimension and 410 feet in the east-west dimension.The base of WMU FU-03 will <br /> be approximately 25 feet below existing ground surface.A composite lining system consisting of a <br /> Pagel <br />
