1. Introduction
<br /> The California Integrated Waste Management Board(CIWMB), Closed, Illegal, and Abandoned
<br /> Site (CIA)program investigates closed, illegal, and abandoned solid waste disposal sites, which
<br /> also includes municipal burn sites. The investigation is generally accomplished in two phases,
<br /> with the first phase being an"office investigation, and the second phase being a"field
<br /> investigation". Field investigations may be non-intrusive or intrusive, and might include
<br /> sampling of the soil and waste. The documentation and data gathered and derived from the
<br /> investigations are evaluated and the findings are the basis for recommended follow-on
<br /> enforcement and remediation actions. If a responsible or parties (RPl f it to com ly with

<br /> iazardous wastes,with concentrations that exceed California Code of Regulations, Title 22,
<br /> Division 4.5, Chapter 11, Article 3 thresholds, are present at the site, then the site would be
<br /> referred to the Regional Water Quality Control Board(RWQCB) and/or the Department of
<br /> Toxics Substance Control (DTSC) for further investigation, and/or enforcement, and
<br /> remediation actions.
<br /> A CIA site where burning of the wastes occurred may contain elevated levels of heavy metals
<br /> such as lead, copper,nickel, cadmium, chromium, and zinc, which are constituents of concern.
<br /> Other constituents of concern might be the presence of total petroleum hydrocarbons (TPH),
<br /> benzene,toluene, ethyl benzene and xylene(BTEX) or diesel, organochlorine pesticides, and
<br /> polychlorinated biphenyls (PCB's),dioxins and furans, and polynuclear aromatic hydrocarbons
<br /> (PAH). Also, dependent upon industrial and commercial or Department of Defense activity in
<br /> the area, low-level radiation-emitting sources could be of concern.
<br /> The statutory authority to investigate solid waste disposal sites is cited in California Public
<br /> Resources Code (PRC) Section 45013, ET seq.
<br /> In February 2001, Mr. Robert McClellon of the San Joaquin County Local Enforcement Agency
<br /> (LEA) contacted Mr. Glenn Young, CIA section supervisor. The LEA requested the CIWMB's
<br /> assistance to determine the status of, and possible remediation of, the illegal disposal sites (IDS),
<br /> and properties collectively referred to in this report as the Santa Fe Road Disposal Site. The
<br /> Santa Fe Road Disposal Site, is comprised of four properties: the Bill Lane Illegal Disposal Site,
<br /> the Lynch Illegal Disposal Site,the Beard property, and the Waller(McAnaly)property, all of
<br /> which previously were part of, or portions were part of,the former Snyder Sanitary Disposal Site
<br /> (SSDS).
<br /> 2. Project Purpose
<br /> The purpose of this Site Investigation was to characterize and determine the horizontal and
<br /> vertical extent of the waste, and assess site conditions in regard to State Minimum Standards per
<br /> California Code of Regulations, Title 27, Sections 20530,20650, and 20820 for: Site Security, `
<br /> Grading of Fill Surfaces (Cover), and Drainage and Erosion control,respectively as cited in
<br /> previous LEA inspection reports. Gas readings were also taken although this issue has never
<br /> been reported as a violation of State Minimum Standards per Title 27, Section 20919. 4
