We are proposing updates to the human health criteria in Table 240 of WAC 173-201A-240, Toxic substances to incorporate existing federal human health criteria for Washington and associated footnotes into the state water quality standards.

Human health criteria are pollution limits on toxic substances that are set to protect people who eat fish and shellfish and drink untreated water from long-term health effects of pollution in rivers, lakes, and marine water in Washington.
For more information, see the rulemaking webpage.
We write rules to implement and enforce state and federal environmental laws and rules. We follow a three-phase process for rulemaking:
- Announcement and development
- Proposal
- 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.
