The Sediment Evaluation Framework (SEF) manual provides a regional framework for assessment, characterization and management (disposal) of sediments in the Pacific Northwest (defined as the states of Washington, Oregon and Idaho) to determine suitability for unconfined in-water disposal. This document addresses the development of a comprehensive evaluation framework governing sediment sampling, testing and test interpretation for determining the potential risk of dredged material, as well as evaluating the suitability of alternative management options. The goal of this manual is to provide the technical and regulatory basis for publicly acceptable guidelines governing environmentally safe assessment and characterization of sediments, thereby improving consistency and predictability in dredged material/sediment management.
