Chapter I I-10 JP 3-28 incidents, regardless of cause, size, location, or complexity. It includes a core set of concepts, principles, terminology, and technologies covering the incident command system (ICS); multiagency coordination systems; unified command; training; identification and management of resources (including systems for classifying types of resources); qualifications and certification; and the collection, tracking, and reporting of incident information and incident resources. The components of the NIMS include resource management, command and coordination, and communications and information management support response. (2) The ICS, multiagency coordination systems, and public information systems are the fundamental elements of the NIMS that direct incident operations; acquire, coordinate, and deliver resources to incident sites; and share information about the incident with the public. (3) When both local and state resources and capabilities are overwhelmed, governors may request interstate and federal assistance; however, NIMS is designed to allow local jurisdictional authorities to retain command, control, and authority over the response. Adhering to NIMS allows all agencies to better utilize limited resources. i. The NRF and NIMS are designed to improve the nation’s incident management capabilities and overall efficiency. During incidents requiring significant federal support, the NRF and NIMS integrate the capabilities and resources of various governmental jurisdictions, incident management and emergency response disciplines, NGOs, and the private sector into a cohesive, coordinated, and seamless national response. A basic premise of both the NIMS and the NRF is that incidents are generally handled at the lowest jurisdictional level possible. In the vast majority of incidents, local resources and local mutual aid provides the first line of emergency response and incident management. A detailed discussion of the NRF and NIMS is contained in Appendix A, “National Incident Management System Overview.” j. Emergency Support Functions (ESFs). ESFs provide the structure to coordinate federal interagency support for a federal response to an incident. They are resources and capabilities grouped to provide federal support to states and federal-to-federal support, both for declared disasters and emergencies under Title 42, USC, Chapter 68, Section 5121, The Robert T. Stafford Disaster Relief and Emergency Assistance Act (commonly referred to as the Stafford Act), where the President has declared a federal disaster or emergency and for non-Stafford Act incidents (non-Stafford Act events are defined as events that have recovery requirements exceeding the capability of individuals and the local community, but do not exceed the capabilities of the state). ESFs are not based on the capabilities of a single USG department or agency, and the functions for which they are responsible cannot be accomplished by any single department or agency. Appendix B, “Emergency Support Functions,” describes the roles and responsibilities of federal departments and agencies as ESF primary agencies.
