B. Ensure that EAP's are reviewed annually and revised or updated in a timely manner. Reviews will include both the specific procedures contained in the EAP's as well as the names, telephone numbers, radio frequencies, and organizations contained in the Communications Directory. C. Ensure that EAP's contain complete descriptions of available communication capabilities and related notification procedures. Appropriate communication directories will also be included. E. Ensure that EAP's contain descriptions of potentially affected areas in the flood plain with inundation maps wherever appropriate, and tables showing travel times and other pertinent information that may be needed by local emergency management officials.
Reclamation prepares dam failure inundation studies and maps for several purposes.
The following directives will apply when the purpose is emergency action planning where the maps and information will be used in Reclamation's EAP's and local warning and evacuation plans. Guidelines for scientific and technical methods of developing the inundation study results can be found in technical literature from the National Weather Service and others. Local conditions may warrant mapping boundaries for other levels of flooding smaller than the design capacity flood. Mapping of operational release flood boundaries would generally only be done in reaches where dam-failure floods are mapped. C. Inundation studies and associated descriptions of flooded areas will be terminated only when the point of adequate floodwater disposal is reached and the flood no longer poses a significant risk to life.
