Antifouling boat paint

Department of Ecology uses this site to share information to engage interested parties and the public about antifouling boat paint studies. For more information, please visit our Antifouling boat paint laws website.

We’ve been studying antifouling paints and ingredients as directed by RCW 70A.445.020. In the most recent draft report, we focus on developing safer criteria and determining whether safer and effective alternatives to copper-based paints are feasible, reasonable, and readily available.

Our 2023 Draft Antifouling Paints in Washington State: Third Report to the Legislature, concluded that the potential restrictions on copper-based paints identified in RCW 70A.334.020(3)(a)(c) won’t take effect and we’ll conduct a second review of relevant studies and information. We’ll submit a follow-up report to the Legislature by 2029.

What are we doing now?
