The Department of Homeland Security (DHS) utilizesPresidential Homeland Security Directives (HSPDs)as the authoritative legal mandate to ensure state and local compliance withNIMS. Specifically,HSPD-5 (Management of Domestic Incidents)is the directive that ordered the creation of NIMS and mandated its adoption by all federal departments and agencies. Crucially, it also made the adoption of NIMS a requirement for state, tribal, and local governments to receive federal preparedness grants and contracts.
While theNational Response Framework(Option A) provides the "how-to" for the response and theFEMA Core Capabilities(Option B) provide the "what" for the goals, it is theHSPD-5(and the laterPPD-8) that provides the "authority" for compliance. DHS monitors this compliance through theNIMS Implementation Assistanceprogram, which requires jurisdictions to report their progress in adopting standardized ICS training, interoperable communications, and resource management protocols.
For theCEDPprofessional, this is the "teeth" behind the NIMS system. If a state fails to comply with the standards set forth in these Presidential Directives, they risk losing millions of dollars in FEMA grant funding. This ensures that when a national disaster occurs, every responding agency is "speaking the same language" and using the same organizational charts, as mandated by the highest level of executive authority. Therefore, the Directives are the guiding force that compels national uniformity in incident management.
