Chapter 173-340 WAC

Ecology plans to amend the administrative and procedural requirements for site cleanups under Chapter 173-340 WAC, Model Toxics Control Act (MTCA) Cleanup regulation (the Cleanup Rule). In this rulemaking we will not change the technical standards for site cleanups in Parts 7 and 9 of the rule, but we plan to: 
  1. Update the title of this chapter. 
  2. Modify the initial investigation, site hazard assessment and ranking, and public notice process in Parts 1 and 3 of the rule. 
  3. Update other administrative and procedural requirements of the cleanup program in Parts 1–6 and Part 8 of the rule. 
  4. Make changes in Parts 1–6 and Part 8 to streamline rule requirements, as well as minor corrections to improve rule clarity and consistency with other laws and rules. 
  5. Make changes in Parts 7 and 9 to clarify language and make corrections without changing the effect of the rule. 
  6. Incorporate changes to the cleanup program specified in Chapter 70.105D RCW, Hazardous Waste Cleanup – Model Toxics Control Act, and Chapter 64.70 RCW, Uniform Environmental Covenants Act.
For more information about the long-range plan to update the rule, visit our Cleanup Rule exploratory rulemaking page.
