The U.S. Nuclear Regulatory Commission (NRC) licensees are currently required to provide advance notice to participating Federally-recognized Tribal governments regarding shipments of irradiated reactor fuel and certain nuclear wastes that pass within or across their reservations. Agreement State licensees will be required to provide advance notifications for certain shipments of radioactive material at the time the applicable Agreement State implements its requirements. The NRC is maintaining and providing a list of Tribal contacts and an interactive map of Tribal boundaries of participating Federally-recognized Tribes that is available on the NRC's public Web site. The list will be published annually in the Federal Register.
