3. Scope of Work <br /> The Closed, Illegal an( Abandoned Site Investigation Unit (CIA) within the Engineering <br /> Branch and San JoaqL in County LEA will be conducting a site investigation to evaluate <br /> the potential presence of LFG at the waste disposal site and to assess the potential for <br /> off-site migration at the Lodi City Landfill (SWIS NO. 39-CR-0023) located in the City of <br /> Lodi, California. The installation of a new gas monitoring network is necessary in order <br /> to protect the public health and safety and the environment pursuant to California Code <br /> of Regulations, Title 2-1 Sections 20921 and 20923. <br /> The objective of this in iestigation is to determine if this old landfill is producing methane <br /> gas which could affect nearby residences and to determine if waste is buried west of the <br /> railroad tracks. The LFS monitoring network will consist of ten gas monitoring wells <br /> total. Ten exploratory t-enches will be excavated. The landfill gas well locations will be <br /> selected by CalRecyclo in conjunction with their environmental consultant Ninyo and <br /> Moore (N&M). The following will be performed as part of this site investigation': <br /> )-w Evaluate site conditions and gas migration potential, <br /> Advance borings to evaluate the presence/absence of wastes and waste <br /> types, if present, and to facilitate construction of landfill gas monitoring <br /> wells, <br /> Collect rE presentative gas samples, <br /> Y- Excavate exploratory trenches to evaluate the presence/absence of waste <br /> and wast3 types, if present, collect soil/waste samples during drilling and <br /> trenching. <br /> Evaluate and summarize gas generation data, and <br /> r Recomm 3nd gas monitoring and/or control system (if necessary). <br /> Sampling will be condi.cted in general accordance with applicable portions of California <br /> Code of Regulations, I itle 22, and Section 66261.10 et. seq. for characterizing <br /> hazardous waste. CaFecycle will use applicable regulatory levels established by DTSC <br /> and applicable federal evels to evaluate and characterize the buried waste. <br /> Amendments to signed docul nents added on February 27,2012 <br /> Lodi City Landfill 5 January 2012 <br /> Site Safety and Health Plar <br />
