Submit by: Online, mail, or at one of the public hearings.

This rulemaking would adopt amendments to chapter 173-201A WAC Water Quality Standards for Surface Waters of the State of Washington. We are considering changes to the freshwater dissolved oxygen criteria and creating new fine sediment criteria.

More information on this rulemaking

We write rules to implement and enforce state and federal environmental laws and rules.  Ecology follows a 3-phase process for rulemaking:

  1. Announcement and development
  2. Proposal
  3. Adoption

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.
