The Department of Energy’s Office of Transportation Safeguards (OTS) maintains a liaison
program to communicate with State, Tribal, and local officials in the event of an accident or
terrorist attack involving an OTS shipment of nuclear weapons, nuclear weapons components, or
special nuclear materials (nuclear shipment). The purpose of the liaison program is to, among
other things, ensure that officials know what actions to take in response to a request for
assistance from OTS.
