Cleanup Rule exploratory rulemaking

The Cleanup Rule sets standards and procedures for cleaning up contaminated sites under Washington's environmental cleanup law, the Model Toxics Control Act (MTCA). Both the rule and law help us remove contamination that can pose risks to your health and the environment. 

In January 2018, we began an exploratory scoping process to update the Cleanup Rule in three stages called "rulemakings." We officially launched the first rulemaking in December 2018. This page tells you how we got there and where we're planning to go next. 

What's an "exploratory rulemaking process?"

The exploratory rulemaking process is a new approach for updating the Cleanup Rule. Instead of updating it all at once, we're doing so in three stages called "rulemakings" over several years. Each rulemaking will focus on a few selected topics. This approach will help speed adoption of the changes that are most urgent for people who use the rule.

What's the plan?

First rulemaking (2018–2020): We're updating parts of the rule that contain administrative and procedural requirements for site cleanups. We won't change the technical cleanup standards during the first rulemaking. For details, read the CR-101 announcement at Chapter 173-340 WAC.

Second rulemaking (expected to begin 2021): We'll update the technical cleanup standards.  

Third rulemaking (expected to begin 2023): We'll address previously deferred topics and new issues that emerge during the first two rulemakings.

How can I participate?

  5. Subscribe to Cleanup Rule email notices.
  6. Check our public events listing for upcoming public listening sessions and opportunities to comment.

What's the Stakeholder & Tribal Advisory Group?

The STAG is a group of about 20 to 25 participants. They'll offer diverse perspectives and advice to Ecology staff during the first and second rulemakings through 2022. STAG meetings will begin September 2019 in Bellevue, Washington. Visit the STAG EZView site to learn more about the group.

How did the 2018 statewide scoping event help shape the rulemakings?

Participants who attended the statewide listening session in April 2018 provided many ideas on which topics we should consider for the official rulemaking process. The online event was hosted in Bellevue and at our regional offices in Lacey, Union Gap, and Spokane. Watch the webinar in your Chrome browser and download the slidesSubscribe to Cleanup Rule emails for more opportunities to comment on specific rule changes.

How long will it take to update the Cleanup Rule?

It may take several rulemakings over the next five to ten years to update this complex rule. Your input during the formal rulemakings will help us plan this work over the coming years; watch for opportunities to comment and attend public meetings. Please note that we may need to change the planned rulemaking and review schedule, based on public input or circumstances beyond our control.
