We invite comments on the draft rule language for Water Quality Standards for Surface Waters (WAC 173-201A).
Comments due: May 21, 2021
Submit by: Online, mail, or at one of the public hearings.
We are considering a change to the aquatic life designated use of salmonid spawning, rearing, and migration on the Chelan River using a use attainability analysis (UAA). A UAA is an approved water quality tool in Washington’s surface water quality standards (WAC 173-201A-440) and is used for removing or revising a designated use for a water body only if that use is not existing or attainable.
Documents for review
We write rules to implement and enforce state and federal environmental laws and rules. Ecology follows a 3-phase process for rulemaking:
- Announcement and development
For each phase of the process, we update the rulemaking web page and notify interested parties. We also file notice in the Washington State Register. To learn more about Ecology’s rulemaking process, read the Frequently Asked Questions.
