This document provides guidance for developing hazard-specific appendices. Hazard-specific appendices offer a means of extending functional annexes to address special and unique response procedures, notifications, protective actions, emergency public information, and other needs generated by a particular hazard. They allow the jurisdiction, in its EOP, to address priorities identified through hazard analysis and to meet detailed regulatory requirements associated with some hazards. A hazard-specific appendix should be prepared for any functional annex that does not, by itself, give enough information to perform the function adequately in the face of a particular high-priority hazard. Some hazards may require that appendices be prepared for various functional annexes; others may affect planning for only one or two functions. Appendices may be long or very brief depending upon need.
