The Portland District uses the Sediment Evaluation Framework for the Pacific Northwest (May 2018) to ensure that our civil works projects and the projects permitted by the Regulatory Program comply with these acts. The SEF helps federal and state agencies in Washington, Oregon and Idaho evaluate the suitability of dredged material for unconfined, aquatic placement in inland waters, and disposal in ocean waters. It is periodically revised and updated to incorporate the latest technical and scientific advances, and incorporate changes in regional policy.
The Portland Sediment Evaluation Team supports our Navigation, Regulatory and Environmental missions, and ensures that dredging and aquatic habitat restoration projects comply with Clean Water Act and Marine, Protection, Research and Sanctuaries Act requirements. The team implements the SEF guidance for the Portland District, ensuring that all Department of the Army-permitted and Corps civil works dredging projects comply with the Clean Water Act and Marine Protection, Research and Sanctuaries Act. The PSET evaluates dredging projects in the state of Oregon and for Washington public ports along the Columbia River, from the Pacific Ocean to river mile 309, approximately 20 miles upstream of McNary Lock and Dam.
Members of the PSET are available to answer questions, assist in the development of sediment sampling plans and help troubleshoot during field sampling. Questions can be directed to the PSET Lead. The PSET agencies include the Corps (lead), EPA Region 10 (co-lead), Washington Department of Ecology, Oregon Department of Environmental Quality, National Marine Fisheries Service and U.S. Fish and Wildlife Service.
An interagency Regional Sediment Evaluation Team prepared the SEF for use throughout the Pacific Northwest. This team is chaired by the Corps’ Northwestern Division and EPA Region 10.
Dredging projects in the state of Washington are evaluated by the interagency Washington Dredged Material Management Program, chaired by Seattle District's Dredged Material Management Office.
Dredging projects in Northern California are evaluated by the San Francisco District's Dredged Material Management Office.
