Description Report to the Legislature Pursuant to SHB 2634 (2018). Boat owners often use hull paints that contain pesticides and other toxic chemicals. Copper-based hull paints have been the most popular antifouling choice since the 1980s. Although they are effective at discouraging organism growth, these paints also have toxic environmental impacts.

In 2011, Washington enacted legislation to ban the use of copper-based antifouling paint starting in 2018. A 2017 follow-up investigation by Ecology showed that some non-copper alternatives might be more harmful to the environment. In 2018, the Legislature delayed the ban and directed Ecology to conduct additional research.

This report summarizes the results of Ecology’s review as directed by the Legislature.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
