Rules for Copper Boat Paint and Water Studies

This law pauses enforcement of current copper boat paint rules until state agencies agree on uniform guidelines, while requiring studies on low-leach-rate paints and high copper levels in harbors.

What This Bill Does

  • Pauses enforcement of regulations on copper-based antifouling paint by the State Water Resources Control Board, regional boards, and the Department of Pesticide Regulation until specific requirements are met.
  • Requires agencies to collaborate to determine best methods for regulating these paints and agree on guidelines for uniform enforcement across the state.
  • States that boats using copper-based antifouling paint approved by the department are considered in compliance while the pause is active.
  • Orders a review of copper boat paint products by January 1, 2028, to decide if standards should be kept, changed, suspended, or replaced with new ones.
  • Requires studies on low-leach-rate paints and high copper levels in saltwater harbors, bays, and marinas to finish by June 1, 2027.
  • Asks agencies to find the best ways to handle high copper levels caused by this paint and post these methods online by January 1, 2028.

Who It Names or Affects

  • The State Water Resources Control Board
  • Regional water quality control boards
  • The Department of Pesticide Regulation
  • Boat owners using copper-based antifouling paint approved by the department
