SIGNIFICANCE AND USE 4.1 Intended Users: 4.1.1 This guide may be used by various parties involved in sediment corrective action programs, including regulatory agencies, project sponsors, environmental consultants, toxicologists, risk assessors, site remediation professionals, environmental contractors, and other stakeholders. 4.2 Reference Material: 4.2.1 This guide should be used in conjunction with other ASTM guides listed in 2.1 (especially Guides E3163, E3240, E3242, E3344 and E3382), as well as the material in the References section. 4.3 Flexible Site-Specific Implementation: 4.3.1 This guide provides a systematic but flexible framework to accommodate variations in approaches by regulatory agencies and by the user based on project objectives, site complexity, unique site features, regulatory requirements, newly developed guidance, newly published scientific research, changes in regulatory criteria, advances in scientific knowledge and technical capability, and unforeseen circumstances. 4.3.1.1 This guide provides a monitoring plan development, execution and analysis framework based on over-arching features and elements that should be customized by the user based on site-specific conditions, regulatory context, and sediment corrective action objectives. 4.3.1.2 Implementation of the guide is site-specific. The user may choose to customize the implementation of the guide for a particular site, especially smaller, less complex sites. 4.3.1.3 This guide should not be used alone as a prescriptive checklist. 4.3.2 The users of this guide are encouraged to update and refine (when needed) the conceptual site model, Project Work Plans and Project Reports used to describe the physical properties, chemical composition and occurrence, biologic features, and environmental conditions of the sediment corrective action project. 4.4 Regulatory Frameworks: 4.4.1 This guide is intended to be applicable to a broad range of local, state, tribal, federal, or internation... SCOPE 1.1 This guide pertains to corrective action monitoring before (baseline monitoring), during (remedy implementation monitoring) and after (post-remedy monitoring) sediment remedial activities. It does not address monitoring performed during remedial investigations, pre-remedial risk assessments, and pre-design investigations. 1.2 Sediment monitoring programs (baseline, remedy implementation and post-remedy) are typically used in contaminated sediment corrective actions performed under various regulatory programs, including the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). Although many of the references cited in this guide are CERCLA-oriented, the guide is applicable to corrective actions performed under local, state, tribal, federal, and international corrective action programs. However, this guide does not provide a detailed description of the monitoring program requirements or existing guidance for each jurisdiction. This guide is intended to inform, complement, and support but not supersede the guidelines established by local, state, tribal, federal, or international agencies. 1.3 This guide provides a framework, which includes widely accepted considerations and best practices for monitoring sediment remedy efficacy. 1.4 This guide is related to several other guides. Guide E3240 provides an overview of the sediment risk-based corrective action (RBCA) process, including the role of risk assessment and representative background. Guide E3163 discusses appropriate laboratory methodologies to use for the chemical analysis of potential contaminants of concern (PCOCs) in various media (such as, sediment, porewater, surface water and biota tissue) taken during sediment monitoring programs; it also discusses biological testing and community assessment. Guide E3382 describes the overall framework to determine representative background concentrations (including Conceptual Site Model [C...
