Contaminant Management Plan, SVRT/BART Extension
Based on preliminary investigations and prior uses of the properties, contaminants are known to be present in
some of the materials that will be disturbed or encountered during project work, including soil, railroad
ballast, groundwater and building materials.
1.3 PURPOSE AND OBJECTIVES
The purpose of the CMP is to present a consistent framework that the designers of the project can operate in
designing and obtaining regulatory approval for specific construction activities within a project segment. This
framework integrates the following key objectives of the CMP:
• Identifying the various scenarios under which large volumes of soil and railroad ballast generated
during construction can be safely reused;
• Identifying maximum acceptable contaminant levels for each reuse scenario, by combining existing
regulatory agency guidance with calculation of risk-based cleanup goals;
• Identifying sampling and analysis, stockpiling, transportation, health and safety, and other procedures
by which soil and ballast must be managed in order to meet safety, regulatory and other standards;
• Defining how the groundwater that will be encountered during construction will be characterized,
properly treated and discharged; and
• Defining how building materials that will be encountered during construction will be characterized,
handled and disposed.
1.4 CONTAMINANT MANAGEMENT PLAN ORGANIZATION
Section 1 presents a description of the project areas covered by the CMP, and the purpose and objectives of
the CMP. Section 2 presents a detailed description of the project, with a separate description for each of the
project segments, which will be designed and built separately. The calculation of risk-based levels for
protection of human health and ecological receptors are presented in Section 3. Section 4 details the
mitigation measures for soil and railroad ballast. Section 5 details the mitigation measures for groundwater as
part of the dewatering activities, and Section 6 presents the mitigation measures for building materials.
Section 7 discusses reporting requirements, and Section 8 lists reference documents.
