Standard Guide for Developing Representative Background Concentrations at Sediment Sites — Framework Overview, Including Conceptual Site Model Considerations
SIGNIFICANCE AND USE
4.1 Intended Use:
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 Updates to CSM:
4.2.1 The CSM should be updated as needed and refined to describe the physical properties, chemical composition and occurrence, biological features, and environmental conditions of the sediment corrective action project (Guide E1689).
4.3 Reference Material:
4.3.1 This guide should be used in conjunction with other ASTM guides listed in 2.1 (especially Guides E3163, E3164, E3240, E3242, and E3344), as well as the material in the References section (including (1)).
4.4 Flexible Site-Specific Implementation:
4.4.1 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.
4.5 Regulatory Frameworks:
4.5.1 This guide is intended to be applicable to a broad range of local, state, tribal, federal, or international jurisdictions, each with its own unique regulatory framework. As such, this guide does not provide a detailed discussion of the requirements or guidance associated with any of these regulatory frameworks, nor is it intended to supplant applicable regulations and guidance. The user of this guide will need to be aware of the regulatory requirements and guidance in the jurisdiction where the work is being performed.
4.6 Systematic Project Planning and Scoping Process:
4.6.1 When applying this guide, the user should undertake a systematic project planning and sco...
SCOPE
1.1 This guide provides an overarching framework for the development of representative sediment background concentrations at contaminated sediment sites. It is intended to inform, complement, and support but not supersede the guidelines established by local, state, tribal, federal, or international agencies.
1.2 Technically defensible representative sediment background concentrations are critical for several purposes (Guide E3242) (1)2. These include sediment site delineation, establishing remedial goals, remedy selection, assessment of risks posed by representative background concentrations, and establishing appropriate post-remedial monitoring plans.
1.3 As part of the overall framework presented in this guide, Guide E3240 provides a general discussion of how Conceptual Site Model (CSM) development fits into the risk-based corrective action framework for contaminated sediment sites. However, not all elements of a sediment CSM need to be considered when developing representative sediment background concentrations; those that do are discussed in detail in Section 7 of this guide.
1.3.1 As additional data are collected and analyzed, the CSM should be updated as needed.
1.3.2 This guide is related to several other guides. Guide E3344 describes how to select an appropriate background reference area(s). Guide E3164 covers the sampling methodologies used in the field to obtain sediment samples (whether from the sediment site or background reference area[s]), and Guide E3163 discusses appropriate laboratory methodologies to use for the chemical analysis of potential contaminants of concern (PCOCs) in sediment samples. Guide E3242 describes how to evaluate candidate background data to obtain representative background data sets (including statistical, geochemical, and forensic considerations) and then how to use them to calculate representative sediment background concentrations.
