RSET is an interagency team, co- chaired by the US <br />Environmental Protection Agency (EPA), Region 10 and the Northwestern Division of the US Army <br />Corps of Engineers (Corps), consisting of federal and state agencies with regulatory responsibilities for <br />managing sediments in Washington, Oregon and Idaho. <br />Appropriate <br />Since 2002, RSET members have worked to develop the SEF for the Pacific Northwest. The SEF <br />Assessment <br />provides a regional framework for the assessment, characterization, and management of sediments in the <br />Northwest. The appropriate assessment of sediments is a critical component of all sediment management <br />activities regardless of whether it is for dredging a navigational channel or investigation and /or <br />remediation of a contaminated sediment site. It is the intention that the SEF, which consolidates the <br />Management <br />existing regional sediment testing guidance manuals, be technically applicable throughout the Pacific <br />Alternatives <br />Northwest for both freshwater and marine sediment assessments. This SEF also includes a discussion of <br />dredged material management alternatives, such as in -water and upland disposal options. <br />Background <br />The Pacific Northwest is unique because of its numerous water dependent economic uses and <br />Contamination <br />significant cultural and natural resources. The waters of the Pacific Northwest provide many benefits, but <br />Threats <br />also receive many threats from contamination. For example, a significant portion of the economy comes <br />from shipping and water - dependent uses, which need navigational dredging to maintain safe transport. <br />Industrial, municipal, and non -point discharges (e.g., agricultural run -off) are typically the sources of <br />contamination to water bodies that are used by salmon and other species protected by the federal <br />Endangered Species Act (ESA). There is a strong need for consistent, comprehensive evaluation and <br />Evaluation <br />regulatory processes for navigation dredging projects, waterway restoration programs, recreational and <br />commercial fisheries management, water - quality protection, sediment - quality protection, and natural <br />resource restoration. <br />To begin the process of developing the Draft SEF, RSET initially conducted a three -day technical <br />scoping workshop on September 11 through 13, 2002, for RSET members and other interested parties <br />Technical <br />from federal and state agencies, and regional Port authorities. The purpose of the meeting was to develop <br />Scoping <br />the scope for preparing an overall plan and process for updating the existing Columbia River Dredged <br />Material Evaluation Framework (DMEF), which was developed in 1998 by an interagency group that was <br />the precursor to RSET (EPA /Corps, 1998). The workshop also was used to gauge the level of agency <br />support for revising the existing Columbia River DMEF and <br />expanding it to encompass the evaluation of sediments throughout <br />Regional Relationships <br />Washington Oregon and Idaho Finally the workshop asked <br />Regional <br />Sediment <br />Evaluation Nw <br />Team Regional <br />Sediment <br />Evaluation <br />Framework <br />attendees to identify technical and policy issues that would need to <br />Regional be addressed during the revision process. <br />Sediment The workshop consisted of breakout sessions covering the <br />Beneficial Management <br />uses or Dredged RSM Demo topics of Process, Biology, and Chemistry.
