The U.S. Vessel Monitoring System (VMS) program type-approves enhanced mobile transceiver units (EMTUs) for use in U.S. fisheries. Currently, the only approved method for transferring VMS data from a vessel to NMFS is by satellite-linked communication services. This final rule amends the existing VMS type-approval regulations to add cellular-based EMTUs (EMTU-Cs) type-approval application and testing procedures; compliance and revocation processes; and technical, service, and performance standards. This rule is necessary to allow for the use of EMTU-Cs and cellular communication service, in addition to satellite-only models, in federally managed fisheries.
