In March 2011, members of the AFWG and other affected registrants received a data request from the California DPR, "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 of underwater hull cleaning on overall copper release from antifouling paint.
With regard to regulatory/standard development activities for antifoulant/foul-release coatings, IPPIC's Antifouling Work Group (AFWG) is coordinating input from the coatings industry into ISO Technical Committee 8 (TC8), which is developing the International Standard Organization (ISO) standard for risk assessment of antifouling biocides and antifouling products.
Two IPPIC work groups have grown out of the Global Forum sessions, and are overseen by IPPIC's Marine Coatings Steering Committee: the Performance Standards for Protective Coatings (PSPC) and Antifouling Work Groups (AFWG).
On the anti-fouling front, IPPIC's AFWG presented a paper on biocide leaching rates and their use in environmental risk assessment of antifouling coatings to the IMO Marine Environmental Protection Committee (IMO-MEPC) in March.
Turning to the IPPIC Antifouling Work Group (AFWG), at a recent IMO Marine Environmental Protection Committee (IMO-MEPC), it submitted a paper on biocide leaching rates and their use in environmental risk assessment of antifoulings.
The AFWG is coordinating coatings industry input into the development of ISO TC8, an ISO standard for risk assessment for antifouling biocides and antifouling products (the Japanese government/JPMA working group drafters).
