AB-1772: Rules to Stop Invasive Mussels in California Waters

This law creates new rules requiring boats to dry out before launching, establishes a licensed inspection program for watercraft, updates plans for water supply systems, and adds fees for nonmotorized vessels.

What This Bill Does

  • Prohibits launching any conveyance until a specified drying period has been completed.
  • Creates an inspection and decontamination program where the department licenses stations to check and clean boats for invasive species.
  • Requires water supply system operators to update their plans to address all invasive mussel species present in their systems as of January 1, 2026.
  • Mandates that a plan be created within 180 days if an invasive mussel is detected in a water supply system after January 1, 2026.
  • Imposes a $20 fee every two years on nonmotorized vessels to fund prevention efforts and requires these vessels to display a state-issued sticker.
  • Changes the legal definition of 'invasive mussel' to mean any nonnative biofouling mussel.

Who It Names or Affects

  • Owners and operators of boats, including those with nonmotorized vessels like canoes or kayaks.
  • Agencies that manage public water supply systems in California.
  • Businesses seeking to become licensed inspection and decontamination stations.
