Archive: Owners paid for the use of non-biocidal coatings

The Shelter Island Yacht Basin, in the Port of San Diego, is offering to help subsidize the removal of copper-based coating from privately owned boats if the owners replace it with non-biocide hull paints.

The so-called Hull Paint Conversion Program (http://www.portofsandiego.org/environment/copper-reduction-program/hull-paint-transition.html) is funded through a $600,000 State Water Resources Control Board grant aimed at reducing copper pollution in San Diego Bay. The money is expected to benefit 200 to 250 boats over three years.

The program offers boat owners $6.30 per square foot to offset the cost of stripping copper-based paint from their boat. For example, a 32-foot power boat with a 350-square-foot hull would be eligible for more than $2,000 toward the cost of hull paint stripping, the program site says.

Boat owners in Shelter Island Yacht Basin must use a participating local shipyard. The work must be completed at one of six area boatyards participating in the program, and the program pays the boatyard directly for the approved costs. The program began in July 2011 and runs until June 30, 2014, or until the funds run out. Recipients would have to pay for application of new, non-biocide hull paint and would have to agree to keep their boats at a slip in the Shelter Island Yacht Basin for three years. Owners who permanently relocate their boat sooner must reimburse the port for the subsidy. Non-biocide hull paints, composed of either silicone or ceramic-epoxy materials, are free of copper, zinc and other polluting chemicals that are released into the water. It can be expected that the non-biocidal coating have to be cleaned in intervals according to the fouling pressure in the harbor. There is no recommendation on this issue in the conversion program.

The Hull Paint Conversion Program was developed after water regulators identified the Shelter Island Yacht Basin as an area where high copper levels exceed federal and state standards. A regulatory order requires the port, marinas, yacht clubs, hull cleaners and boaters to reduce copper pollution in the area by 76% by 2022. The Port of San Diego is under orders to drastically reduce copper pollution levels by 2022. The American Coatings Association, which represents coating manufacturers, has said such legislation could “serve as a terrible precedent for other U.S., foreign and international authorities to follow.
