SECTION 1 <br /> Introduction <br /> The Forward Landfill is an active, permitted Class II and Class III disposal facility that is owned and <br /> operated by Forward, Inc. (Forward), a subsidiary of Republic Services. The landfill is located <br /> approximately seven(7)miles southeast of the City of Stockton in San Joaquin County. <br /> This report presents the design and construction documents for the development of Waste <br /> Management Unit (WMU) FU-14 at the Forward Landfill. WMU FU-14 is located directly east of <br /> WMU FU-10 in the area formerly known as the Austin Road Landfill expansion area. The location <br /> of WMU FU-14 is shown on the Site Plan(see the Construction Drawings in Appendix A). <br /> The design and construction documents for WMU FU-14 were prepared in accordance with <br /> Forward's approved Joint Technical Document (JTD), Waste Discharge Requirements (WDR Order <br /> No.R5-2014-0006), and applicable regulations. The applicable state regulations include California <br /> Code of Regulations (CCR), Title 27, Division 2 (Title 27). The federal regulations are incorporated <br /> in 40 Code of Federal Regulations (CFR), Parts 257 and 258 (Subtitle D). Some of the provisions of <br /> particular importance regarding the design include: <br /> • The WMU FU-14 liner and leachate collection and removal system (LCRS) design conform to <br /> the prescriptive standards of both Title 27 and Subtitle D. <br /> • WMU FU-14 has been designed to control inundation, washout, erosion, and slope failure <br /> resulting from flooding caused by a 24-hour storm with a 1,000-year return period. <br /> • Seismic studies have indicated that the Forward Landfill site is not located within 200 feet of a <br /> Holocene aged fault (GeoSyntec, January 2001) and therefore complies with the regulatory <br /> provision regarding active faults. <br /> The base liner in WMU FU-14 will encompass approximately 11 acres and is approximately 700-feet <br /> in the north-south dimension and 700-feet in the east-west dimension. The top of clay liner on the <br /> base of WMU FU-14 will be at approximately elevation 7-feet to 15-feet,which is about 25 to 33-feet <br /> below the surrounding ground surface. A composite lining system consisting of a 2-foot-thick clay <br /> liner overlain by a 60-mil,high-density polyethylene(HDPE)geomembrane, and LCRS consisting of <br /> 1 foot of granular drainage material will be constructed on the WMU FU-14 base. <br /> The base liner of WMU FU-14, and future cells constructed to the east of WMU FU-14, will be <br /> sloped to drain at a minimum one percent grade to the east. Two temporary, composite lined sumps <br /> will be constructed at the eastern edge of the WMU FU-14 base. Leachate will be collected and <br /> pumped out of tanks located in the composite lined sumps. <br /> WMU FU-14 REPORT.DOC 1-1 <br />
