Restoration Activities
Case: Lower Duwamish River, WA

Final Restoration Plan and Programmatic Environmental Impact Statement Available:

The Lower Duwamish River Natural Resource Trustees (Trustees) have released the Final Restoration Plan & Programmatic Environmental Impact Statement (RP/PEIS). The Final RP/PEIS was developed after considering public comments received on the two previous drafts. The Final RP/PEIS presents the types of restoration project desired and outlines priority areas for restoration in order to recover natural resources lost or injured by the release of hazardous substances in the Lower Duwamish River.

Final-Lower Duwamish River NRDA Restoration Plan and Programmatic Environmental Impact Statement (2013)

Background on Restoration Process:

Natural resource damage assessment (NRDA) is the process of assessing the nature and extent of natural resource injuries and determining what is necessary to restore, replace or acquire the equivalent of those resources. In the case of the Lower Duwamish River, there have been numerous releases of hazardous substances that have resulted in natural resource injuries. To streamline the NRDA process and provide a systematic approach to restoring injured natural resources, the Trustees developed the RP/PEIS. The RP/PEIS describes how Trustees will evaluate projects proposed for restoring natural resources injured by hazardous substance releases in the Lower Duwamish River.

The Trustees involved in the development of the RP/PEIS include the U.S. Department of Commerce, National Oceanic and Atmospheric Administration (NOAA); U.S. Department of the Interior, Fish and Wildlife Service (FWS); Washington State Department of Ecology; Washington State Department of Fish and Wildlife; Suquamish Tribe and Muckleshoot Indian Tribe.

History of Public Involvement for RP/PEIS:

Previous public involvement has included a scoping process as well as a public meeting to provide an update on the status of the RP/PEIS. The scoping process allowed the public to provide input and comments on the scale, focus, and content of the RP/PEIS and allowed for public involvement at the earliest stage of the process. Scoping also allowed the public to submit ideas for desired restoration projects. Two scoping meetings were held by the Trustees on June 6, 2007, at the South Park Community Center and June 7, 2007, at the Tukwila Community Center. In addition to the public meetings, the Trustees requested written comments from stakeholders and the public on the scope and scale of the Draft RP/PEIS. The period for submitting comments was from May 25, 2007, to August 1, 2007. On Oct 31, 2007, a Scoping Report was released that summarized all of the written comments received as well as the comments made during the two public meetings.

Download meeting presentations and scoping documents:

A third public meeting was held on March 12, 2008, at the South Park Community Center to provide an update on the status of the RP/PEIS development process, provide additional information on the content and focus of the document and review major comments received during the scoping process.

A previous draft RP/PEIS was made available for public review on May 22, 2009 with the comment period ending on July 28, 2009. In the Supplement to the Draft Programmatic Restoration Plan & Programmatic Environmental Impact Statement, the Trustees added more detail about the injury assessment and restoration valuation methodology used in the LDR/NRDA, as requested in some of the comments received on the previous draft, and made some other more minor changes to address other comments.

Further opportunities for comment will also be provided through public review and comment on documents contained in the Administrative Record and on Environmental Assessments for individual restoration projects.
