Some form of labelling should be placed on MPC formulations that have been registered, or permitted for use as antifoulants, or are exempt from registration by the National Registration Authority so that applicators know that all such products meet current local standards. This would assist in the protection of both human health and of the environment.
The application, maintenance and removal of all antifouling coatings should only be done above the tidal zone at facilities capable of meeting New Zealand and Australian state, territory and commonwealth regulatory requirements for dangerous goods, occupational health and safety and environmental protection, and appropriate standards of best practice. The sale of antifoulants should be restricted to facilities capable of meeting the above requirements. Therefore, Australia and New Zealand should work towards uniform licensing procedures for such facilities.
Further restrictions on the use of tributyltin in Australian waters are not recommended until adequate alternatives are available. The basis of this recommendation is that efficient antifoulants are required to ensure that exotic species are not imported into local waters. Exotic species can have major impacts on local species and local aquaculture. The effects of tributyltin are reversible and will be confined to areas dealing with large vessels. The impacts of exotic species are unpredictable and may not be able to be controlled or restricted. Conversely, the impacts of exotic species may not be reversible. It is proposed to allow for more restrictions on the use of tributyltin paints on larger vessels (>25m) operating in confined waterways, bays, rivers or estuaries.
