Chapter 173-303 WAC, Dangerous Waste Regulations

Proposed rulemaking

August 9, 2018 - October 5, 2018

The proposed revisions include recent changes to the federal hazardous waste regulations and changes initiated by the state. We had intended to also propose dangerous waste pharmaceutical regulations similar to Environmental Protection Agency’s (EPA) 2015 proposed hazardous waste pharmaceutical rule. We decided not to do this, since we discovered there could be significant changes between EPA’s proposed rule and the final adopted regulations. We intend to restart our rulemaking process for this set of rules in the near future, as EPA has indicated they intend to adopt a final regulation this fall.
In response to informal public comments we received last fall on our draft revisions, we changed:
  • The definition of “weekly inspection.”
  • Language about hazard labels.
  • Clarifications on other unclear language.
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:

  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.
