On December 14, 2015, the United States Coast Guard (USCG) announced a preliminary decision about our request for the approval of the Most Probable Number (MPN) method – a method used in determining the biological efficacy of a UV-based ballast water management system. In the announcement, it was stated that the MPN method is not equivalent to the Environmental Technology Verification (ETV) Protocol vital stain method.

We strongly believe that this preliminary decision by the USCG should be reversed. Our application for the approval of the MPN method presents solid scientific facts that prove the method is consistent with U.S. Law, accurate, and just as protective of the environment, if not even more so, than the vital stain method. The MPN method’s use is ubiquitous, including the protection of human health in drinking water applications, and is supported by the world’s foremost scientific experts.

We are proceeding with an appeal, and considering all other options. We remain focused on our pursuit of USCG Type Approval, and providing customers with robust ballast water treatment systems.
