RCW 70A.445.005: Intent.

Antifouling paints and coatings are necessary for the proper performance and preservation of boats and other marine craft. However, many of these substances contain copper, biocides, and other chemicals that are toxic to many aquatic organisms, including salmon. The legislature intends to phase out the use of copper-based and other antifouling paints and coatings that pose an undue threat to the environment when used on recreational water vessels. The legislature also intends to encourage the development of safer alternatives to traditional antifouling paints and coatings.
