BOISE – The Idaho Department of Environmental Quality (DEQ) released the 2023 Triennial Review of Idaho Water Quality Standards.

Under the Clean Water Act § 303(c) and federal regulation 40 CFR 131.20, the plan must review, update, or modify Idaho’s water quality standards every three years. As part of this 2023 triennial review process, DEQ reviewed current and past priorities and published white papers outlining our priorities.

On September 29, 2023, DEQ held a public meeting in person and virtually, requesting verbal and written feedback from stakeholders regarding these priorities. View the final report and public comments on our website.
