'No standard format or organization is specified for a local government's emergency plan.... While the organization of local plans is not specified, there are a number of emergency functions that should be covered in the plans of each local jurisdiction. First, it is essential that the local plan outline the organizations, systems, and procedures which add up to the jurisdictions basic emergency operating capability. This refers to the jurisdiction's ability to handle any of the types of major emergency identified in the hazard analysis. The elements of this basic operating capability are usually reflected in the jurisdiction's Basic Plan and in certain additional parts or annexes in the overall local emergency plan. The Basis Plan is a relatively brief 'umbrella' for the balance of the emergency plan, and as such covers organization, responsibilities, and operations in any type of emergency. "The parts of the local plan which reflect the basic operating capability are those of general applicability, outlining functions needed in any emergency severe enough to call for coordinated emergency operations. These supporting parts of the plan are often designated as annexes to the Basis Plan, and should cover: (1) Direction and Control, spelling out local emergency organization for centralized direction of coordinated operations by key officials. Emphasis is on EOC organization and functions. (2) Warning, spelling out responsibilities and procedures for warning the population of impending threats. (3) Emergency Communications. (4) Emergency Public Information, spelling out responsibilities and procedures for getting official information and instructions to the public promptly, before, during, and as necessary after an emergency. "Radiological Defense for both peacetime and attack emergencies is sometimes also covered in an annex of general applicability. However, it is preferable to cover radiological defense operations for attack emergencies separately from those for peacetime emergencies (e.g., a transportation accident involving radioactive material, or a severe accident at a nuclear power plant). This is because different concepts of operation, assessment methodologies, and protective actions are involved in peacetime radiological emergencies. "The balance of the local plan addresses operations which many be required in specific types of emergencies". (DCPA, Standards for Local Emergency Preparedness (CPG 1-5) 1978, p. 16) "Certain additional nuclear-related contingencies should be covered in local emergency plans, where applicable. These may include (1) plans for peacetime radiological emergencies.... (2) plans for warning the population should warning ever be received of an accidental missile launch,, or any other unauthorized or unexplained incident involving a possible detonation of a nuclear device; and (3) plans for a possible threat by terrorists or criminals, involving an alleged nuclear device or weapon".
