KEY LEGAL AND POLICY DOCUMENTS
1. National Guidance
a. HSPD-5, Management of Domestic Incidents. HSPD-5 assigns the Secretary of
Homeland Security as the principal federal official for domestic incident management to
coordinate the USG’s resources utilized to prepare for, respond to, or recover from terrorist
attacks, major disasters, or other emergencies. The USG assists state and local authorities
when their resources are overwhelmed or when federal interests are involved. HSPD-5
directs that SecDef shall provide support to civil authorities for domestic incidents as
directed by the President or when consistent with military readiness and appropriate under
the circumstances and the law. SecDef retains command of military forces providing
DSCA. Additionally, HSPD-5 directs the Secretary of Homeland Security to lead and
manage the development of NIMS to provide a consistent nationwide approach for federal,
state, and local governments to work effectively and efficiently together to prepare for,
respond to, and recover from domestic incidents.
b. PPD-8, National Preparedness. PPD-8 is aimed at strengthening the security and
resilience of the US through systematic preparation for the threats that pose the greatest
risk to the security of the nation, including acts of terrorism, cyberspace attacks, pandemics,
and catastrophic natural disasters. National preparedness is the shared responsibility of all
levels of government, the private and nonprofit sectors, and individual citizens. Everyone
can contribute to safeguarding the nation from harm. As such, while this directive is
intended to galvanize action by the USG, it is also aimed at facilitating an integrated, all-
of-nation, capabilities-based approach to preparedness.
c. NSHS. Prepared for the President by the Office of Homeland Security, this
document lays out the strategic objectives, organization, and critical areas for HS. The
strategy identifies critical areas that focus on preventing terrorist attacks, reducing the
nation’s vulnerabilities, minimizing the damage, and recovering from attacks that do occur.
d. The Homeland Security Act of 2002. This act established DHS to coordinate all
federal HS activities to protect the nation against threats to the homeland. To better
facilitate the overarching HS mission, Congress established DHS by merging numerous
agencies into a single department.
e. The Robert T. Stafford Disaster Relief and Emergency Assistance Act (Title
42, USC, Chapter 68, Section 5121). This act sets the policy of the USG to provide an
orderly and continuing means of supplemental assistance to state and local governments in
their responsibilities to alleviate the suffering and damage that result from major disasters
or emergencies. It is the primary legal authority for federal participation in domestic
disaster relief. Under the Stafford Act, the President may direct federal agencies, including
DOD, to support disaster relief. DOD may be directed to provide assistance in one of three
different scenarios: a presidential declaration of a major disaster, a presidential order to
perform emergency work for the preservation of life and property, or a presidential
declaration of emergency.
