Anti Fouling Paint Manufacturers Taking Aim At California Hull Cleaners

The anti fouling paint industry is taking direct aim at California hull cleaners and it seems clear that their intent is to dramatically curtail or even eliminate the in-water hull cleaning of pleasure craft in California. Please read below an excerpt taken from the web site of the American Coatings Association (ACA), who are the lobbying group for the anti fouling paint industry (bold type mine):

ACA and its Anti Fouling Work Group (AFWG) contend that anti fouling paints release copper at a restricted rate and that excessive underwater hull cleaning practices contribute a high percentage of the release of copper into marinas. Further, modern anti fouling copper-based coatings are designed to be effective without frequent cleaning and cleaning schedules should follow manufacturers’ recommendations.

In March 2011, members of the AFWG, and other affected registrants, received a data request from the California Department of Pesticides Regulation (DPR) titled, “Clarification of Leach Rate Determination, Notice of Additional Data Requirements and Meeting Regarding the Reevaluation of Copper Based Anti-fouling Paint Pesticides.” The data requirement called for, among other things, a protocol to accurately determine the impact underwater hull cleaning has on overall copper release from anti fouling paint.

ACA’s AFWG developed and submitted, in June 2012, the “In Water Hull Cleaning and Passive Leaching Study Protocol” to DPR and coordinated the funding of the study amongst copper suppliers and copper-based anti fouling registrants in California. The purpose of this study is to ascertain the effect of underwater hull cleaning methods on various types of anti-fouling paints and to quantify the amount of copper that enters the water column from passive leaching. The study will test the most contemporary anti-fouling paints used in Shelter Island Yacht basin. This includes ablative coatings, which were not properly addressed in prior studies. ACA contracted with the Space and Naval Warfare Systems Command, a subgroup of the U.S. Navy, and Scripps Institution of Oceanography and appointed a study overseer to visit the site and ensure adherence to the protocol. The study commenced on Aug. 13, 2012, and a final report of the results is expected in the spring of 2013. It will be published in the Journal of Biofouling and DPR will use the results of the study to inform the development of mitigation strategies.

The results of the study and the mitigation strategies developed by DPR will not just determine the course for anti-fouling coatings in California, but will have global implications.


New Copper Coatings Bill Introduced in California Legislature


The paint manufacturers and the corporations that provide them with copper are very much interested in making sure they are able to continue to sell copper-based anti fouling paints in California. Faced with continuing legislative and regulatory pressure to reduce the copper contribution to our coastal waterways from anti fouling paint, they are attempting throwing hull cleaners under the bus. All previous studies done in California have shown that in-water hull cleaning is responsible for about 5% of the copper that comes from anti fouling paint. The rest comes from passive leaching, which these paints do 24/7/365. ACA and the companies they represent have funded this new study and it's a sure bet the results they come up with will show that hull cleaners are responsible for a much higher percentage of that copper (estimates are as much as 50%, a ten-fold increase.)

In any event, this is a clear case of the fox guarding the henhouse. The coming months will be very interesting. Stay tuned if you are a boater that enjoys have a clean bottom.

Care to cite those studies...

Re: Anti Fouling Paint Manufacturers Taking Aim At California Hull Cleaners

So this is different than the Certified "Clean Marina" recommendations ? Couple years ago divers here (60 nm north of Shelter Island) had to take a certification class on "Clean Marina Practices". Stressed cleaning methods, practices and materials.
What are the manufacturers gonna recommend ? Once a month with baby diapers or once a year with scrapers ?
Of course the manager of my yard already says if I sailed more I wouldn't need to clean, but I've never seen a boat able to "self clean". It would be like that movie with the exploding bus, always moving at 5 kts. or above.

I assume you are Newport? I believe the course you are referring to was the California Professional Divers Association In-water Hull Cleaning Best Management Practices Certification Course, of which I was an instructor. And yes, this is different. This is the paint manufacturers telling the state agency responsible for regulating anti fouling paints that it's not their products that are the problem, it's the hull cleaners. The manufacturers would have you believe that their products do not need cleaning, which if you keep a boat in the water in California, you know to be patently untrue. So what they expect boaters to do is unknown. We believe that they may push for drastically reduced cleaning frequencies, or possibly a moratorium on hull cleaning for some specified period, like a year or two. We don't really know yet.

Noooooo! I too have heard the sail it above 5kts and it will all go away. How you going to do that with 3 months of crud on there. Still even with fresh paint and weekly sails above 6kts the crud just grows like crazy in my experience. Fast-Bottom what are we going to do, anchor out and just risk a ticket while cleaning our bottoms? Sorry to be selfish, what are bottom people going to do to make the mortage payment.

That's my question as well. But keep in mind, the report has only gotten to the DPR today and nothing is written in stone yet (hopefully.) My goal right now is to make boaters aware of what's coming down the pike. If you are a member of the Recreational Boaters of California organization, I recommend you find out where they stand on this and let them know your position as well. They are a very powerful advocate for boaters in this state.

Dana Point, Same Sheriff on Harbor Patrol, just 14 nm south.
Every time I've painted over the last 12 years I've thought it's the last time I'll have a high copper paint. Just a quick reading of the studies make me think the outcome at some point will be "non-biocide" paint. At that point it will be a win-win for all, starving divers can feed their families, boaters have to clean often, but at least they CAN clean.
After suffering through some sort of "moratorium" it won't hurt so much.

You must think that hull cleaners have some sort of fat bank account or backup job to fall back on. I guarantee that if a moratorium were to occur, most of the hull cleaners in the state would go out of business and have to find something else to do. Me included.

Re: Anti Fouling Paint Manufacturers Taking Aim At California Hull Cleaners

I really don't think you guys are making a fortune at $35 a pop Fast.
I think since the state and some local agencies have tried several times to institute copper based paint bans, it would not surprise me to see an "end run" by those concerned.
It does not seem unusual for government and others to institute regulations that are unworkable for all concerned. For example, if they ban in water cleaning, owners have no reasonable alternative, divers and others are negatively impacted to the point of desperation. So, in a month or so the regulation is dropped in favor of a copper paint ban and it suddenly becomes a moderate compromise that sounds better to all involved. Maybe it's a little paranoid but a quick look at the studies says only non-biocide paints produce zero leaching, so it seems this might just be an attempt to gain more support for banning copper.
