Hazardous Waste & Toxics Reduction

HWTR Open Rulemaking

Ecology has a process that we follow for rulemaking.  For each phase of the process, Ecology updates the information on our website and sends notice to interested parties. We also file notice with the Office of the Code Reviser, which is published in the Washington State Register. To learn more about Ecology’s rulemaking process, visit the Frequently Asked Questions.

The Hazardous Waste and Toxics Reduction (HWTR) Program is currently working on rulemaking listed below. Follow the links below to find more information about the rulemaking you are interested in.
