Chapter 173-333 WAC

Ecology proposes to amend Chapter 173-333 Washington Administrative Code (WAC) Persistent Bioaccumulative Toxins [proposing title change to Chemical Action Plans]. This rule identifies:
Criteria for persistence, bioaccumulation, and toxicity (PBT) used to identify a chemical as a PBT.

  • Provides a list of chemicals for which Chemical Action Plans (CAPs) may be developed.
  • Identifies the CAP development process.
  • Details the CAP contents.

The CAP is a comprehensive plan to identify, characterize, and evaluate all uses and releases of specific chemicals or group of chemicals. Each CAP recommends actions to protect health and the environment.
