Vessel Fouling Regulations

Summary of Current Management Frameworks for Vessel Fouling.

This table summarizes domestic and international regulations, proposed management actions, recommendations, guidelines, and codes of practice aimed towards preventing AIS introductions through fouling. (Excerpt from California State Lands Commission Final Report on Commercial Vessel Fouling in California)

Existing Hull Fouling Legislation
Australia has implemented hull fouling measures, which only apply to vessels under 25m in length and are in the process of becoming mandatory. These measures include: (1) Cleaning the vessel's hull within one month prior to arrival; or (2) Applying antifouling paint within one year prior to arrival; or (3) Booking the vessel to be hauled out and cleaned within one week after arrival.

Upcoming California Hull Fouling Legislation
Assembly Bill 740 (AB 740)
This bill defines the term "vessel fouling", requires removal and recordkeeping of vessel fouling organisms from hull, piping, propellers, sea chests, and other submerged portions of one of those vessels at least every 60 months, and requires inwater cleaning of the submerged portion of a vessel while in the waters of the state to be conducted using specified procedures. Additionally, the bill requires the commission, by January 1, 2010, to develop and adopt regulations governing the management of vessel fouling on those vessels arriving at a California port or place, to protect the waters of the state.
