4.1 This guide is intended for use within a RBCA process or other risk-based framework for protection of human health and the environment that is based on an evaluation of sources, exposure pathways, and receptors.
4.2 This guide is intended to identify the factors that should be considered in the selection and implementation of an appropriate remedial action to address COCs present in environmental media at the site at concentrations above the remedial action levels. The specific process used to select the remedial action will vary widely from site to site. However, in all cases, the selected remedial action should be both a protective remedial action (that is, achieves the risk-based remedial action objectives) and an acceptable remedial action (that is, satisfies the non-risk remedial action objectives).
1.1 This guide covers the selection of appropriate remedial actions at sites where a release of chemicals (for example, vapor-phase, dissolved-phase, or non-aqueous phase liquids (NAPL)) into the environment has occurred. This overall remedy selection process is illustrated in Fig. 1. The guide is intended to be applied within a risk-based corrective action (RBCA) framework.
1.5.1 Development of risk-based remedial action objectives that includes identification of complete exposure pathways and numeric remedial action levels (Section 5).
1.5.2 Development of non-risk remedial action objectives based on resource protection and other non-risk considerations. Resource protection objectives typically include numeric remedial action levels while other non-risk criteria are typically non-numeric and may include: remediation timeframe, implementability, cost effectiveness, regulatory compliance, property use requirements, liability control, and community concern (Section 5).
1.5.3 Evaluation of protectiveness to identify protective remedial actions that will be effective and timely for each risk-based remedial action objective for the site (Section 6).
1.5.4 Evaluation of the retained remedies using the non-risk remedial action objectives to identify acceptable remedial actions that satisfy the minimum level for each non-risk criterion (Section 7).
1.5.5 Remedial action selection to select the acceptable remedial action to be implemented at the site (Section 8).
