The Department of Energy's diverse mission is directly related to helping resolve many of the energy, environmental, and nuclear security challenges that face the Nation. As a consequence, the Department's operations involve dangerous substances such as nuclear and hazardous materials. In this context, the Department must: (i) ensure that it can quickly and effectively respond to emergencies at its facilities; and, (ii) be prepared to maintain or resume mission-related work following an emergency. The National Nuclear Security Administration (NNSA) has responsibility for developing the Department's overall emergency preparedness and continuity planning policy.
