The Oregon Department of Environmental Quality is preparing the 2024 Water Quality Standard Triennial Review. The Triennial Review is required under the Clean Water Act and is a report and workplan outlining DEQ's priorities when developing water quality standards. It also includes a workplan listing priority water quality standards projects that DEQ plans to initiate or complete between January 2025 and December 2027. Prior to finalizing the workplan, DEQ invites the public to comment on it.
DEQ has released a proposed triennial review 2025-2027 workplan for public input. All public comments must be received by 5 p.m., Dec. 2, 2024. See 2024 triennial review documents below, for a copy of the workplan, a fact sheet about the Triennial Review, and the public notice. The public notice provides multiple options for giving public comment.
After considering comments received during the public comment period, DEQ may adjust priority projects and establish a final workplan for the water quality standards program for January 2025 through December 2027.
Included in this proposed 2024 Triennial Review are four Outstanding Resource Water nominations for consideration as priority projects. The nomination letters and supporting documents are available for review. The Outstanding Resource Water web page has more information on nominations and current designations.
