During the closure cap extension project, minor refuse will be excavated during <br /> drilling of two new LFG extraction wells. Refuse will be hauled and disposed <br /> off-site at a certified disposal facility. The area will be cleaned after the completion <br /> of the project. <br /> 3.5 FIRES <br /> During the initial closure of CHSL, fire break setbacks were established around the <br /> entire landfill. The County's portion of the closure cap extension project falls in the <br /> setback for firebreak. A Knox —Box is installed in front at the entrance gate to <br /> enable the local fire authority to enter CHSL during a fire. <br /> 3.6 LANDFILL GAS <br /> 3.6.A Landfill Gas migration monitoring <br /> The extension of the closure cap area falls within the current LFG migration <br /> monitoring network of the Landfill (GW-1 and GW-7) (Plan Sheet 2). <br /> Therefore, no new migration monitoring wells will be added in this project. <br /> All of the existing migration monitoring wells have been in compliance with <br /> AOL regulations for off-site migration with the aid of the LFG system. <br /> 3.6.6 Landfill Gas collection <br /> A LFG collection system was installed and began operating on December <br /> 2001 as a corrective action against LFG migration and VOC impacts to <br /> groundwater. The LFG system consists of a Flare station and LFG <br /> extraction wells installed in the Landfill (Plan Sheet 2). Currently there are <br /> 39 LFG extraction wells. Extracted LFG is burned at the flare station. Two <br /> new LFG extraction wells will be installed in the Caltrans closure area in the <br /> closure cap extension project (Plan Sheet 2, 3). <br /> Closure Plan Revised Addendum San Joaquin County <br /> Corral Hollow Sanitary Landfill 4 Department of Public Works <br /> October 6. 2011 Solid Waste Division <br />
