Would an Influenza Pandemic Qualify as a Major
Disaster Under the Stafford Act?
This report provides a legal analysis of the eligibility of an influenza pandemic
(flu pandemic) to be declared by the President as a major disaster under the Robert
T. Stafford Disaster Relief and Emergency Assistance Act. In 1997, the discovery
of a virulent H5N1 strain of avian influenza (bird flu) raised the possibility of a flu
pandemic occurring in the United States. In such an event, the Stafford Act could
provide authority for federal assistance. Although it is widely agreed that emergency
assistance under the Stafford Act could be provided by the President in the event of
a flu pandemic, questions remain as to whether major disaster assistance would be
available. An analysis of the Stafford Act suggests that this issue was not addressed
by Congress when it drafted the current definition of a major disaster, and that neither
inclusion nor exclusion of flu pandemics from major disaster assistance is explicitly
required by the current statutory language.
In the 109th Congress, § 210 of S. 3721 would have made any outbreak of
infectious disease explicitly eligible for major disaster assistance, but it was not

Would an Influenza Pandemic Qualify as a
Major Disaster Under the Stafford Act?
The Threat of an Influenza Pandemic
In 1997, a virulent strain of avian influenza (bird flu) was discovered in Asia.
Hundreds of people in Europe and Asia have suffered from severe illness caused by
the virus, but the virus has not, at this time, developed the ability to spread easily
from person to person.1 Were that to happen, a global pandemic could ensue. The
Department of Health and Human Services (HHS) defines pandemic influenza as a
“virulent human flu that causes a global outbreak, or pandemic, of serious illness.
Because there is little natural immunity, the disease can spread easily from person to
person.”2 According to HHS, an influenza pandemic (flu pandemic), “unlike natural
disasters or terrorist events,” could be widespread, affecting multiple areas of the
United States and other countries at the same time. They postulate that a pandemic
could be an extended event, with multiple waves of outbreaks in the same geographic
area. HHS further maintains that each outbreak could last from six to eight weeks3
and waves of outbreaks may occur over a year or more. In the event of a flu
pandemic, the Robert T. Stafford Disaster Relief and Emergency Assistance Act
could provide authority for federal assistance to individual victims and affected
communities. The specific types of assistance that could be made available are4
discussed below.
An Overview of the Stafford Act
The Robert T. Stafford Disaster Relief and Emergency Assistance Act (the
Stafford Act)5 authorizes the President to issue major disaster or emergency
declarations in response to incidents that overwhelm state and local governments.
Either type of declaration would authorize the distribution of a wide range of federal
aid to individuals and families, certain nonprofit organizations, and public agencies,
but major disaster and emergency classifications each trigger different kinds and
amounts of assistance from the federal government.

Under the Stafford Act, a major disaster is defined as
any natural catastrophe (including any hurricane, tornado, storm, high water,
winddriven water, tidal wave, tsunami, earthquake, volcanic eruption, landslide,
mudslide, snowstorm, or drought), or, regardless of cause, any fire, flood, or
explosion, in any part of the United States, which in the determination of the
President causes damage of sufficient severity and magnitude to warrant major
disaster assistance under this chapter to supplement the efforts and available
resources of States, local governments, and disaster relief organizations in6
alleviating the damage, loss, hardship, or suffering caused thereby.
A major disaster declaration authorizes the President to offer a variety of federal
assistance, although none is specifically required to be provided.7 The types of
general federal assistance available include directing federal agencies to support in
assistance efforts, coordinating assistance efforts, providing technical and advisory
assistance, and distributing supplies and emergency assistance. Under the major
disaster classification, there are also more specific provisions, including repair and
restoration of federal facilities, removal of debris, housing assistance, unemployment
assistance, emergency grants to assist low-income migrant and seasonal farmworkers,
food coupons and distribution, relocation assistance, crisis counseling assistance and
training, community disaster loans, emergency communications, and emergency
public transportation.8
In contrast the Stafford Act defines an emergency as
any occasion or instance for which, in the determination of the President,
Federal assistance is needed to supplement State and local efforts and
capabilities to save lives and to protect property and public health and safety, or9
to lessen or avert the threat of a catastrophe in any part of the United States.
An emergency declaration authorizes limited federal assistance when compared10
to a major disaster classification. The emergency declaration would not authorize
grants, unemployment assistance, food coupons, crisis counseling assistance and
training, or community disaster loans as would be available through a major disaster
declaration. An emergency declaration would authorize technical and advisory
assistance to affected state and local governments for certain needs; emergency
assistance through federal agencies; clearance of debris; housing assistance; and
assistance in the distribution of medicine, food, and other consumable supplies. The
total amount of assistance available is also limited in an emergency declaration to $5

must be notified if the $5 million ceiling is breached.”11
Executive Branch Responses to
Potential Pandemics
Although “neither disaster declarations nor congressional appropriations were
issued for the 1957 Asian flu pandemic ... which resulted in almost 70,000 deaths in
the United States [and] was one of the deadliest catastrophes of its time,”12
emergency declarations under the Stafford Act in the event of an outbreak of
infectious disease are not unprecedented. In 2000, the detection of West Nile virus
in New York and New Jersey was used as the basis of an emergency declaration
under the Stafford Act.13 Despite the lack of a disaster declaration during the 1957
pandemic, a flu pandemic would likely qualify under the broad category of “any
occasion or instance” in the statutory definition of an emergency.14
However, recent events have led to uncertainty over whether a flu pandemic is
eligible for major disaster assistance under the Stafford Act.15 In 2005, various
federal agencies participated in TOPOFF 3, a national level exercise that simulated
various security-related events, including a biological attack causing an outbreak of
pneumonic plague in the United States.16 The Federal Emergency Management
Agency (FEMA), the agency responsible for administering the Stafford Act, was
among the participants in that exercise. During TOPOFF 3, as well as during an
earlier exercise, FEMA interpreted “biological disasters” as ineligible for major
disaster assistance because such incidents were not explicitly mentioned in the
Stafford Act.17

Subsequently, in May of 2006, the Homeland Security Council issued its
Implementation Plan for the National Strategy for Pandemic Influenza,18 which
stated that “the President could declare either an emergency or a major disaster with
respect to an influenza pandemic,” potentially contradicting the earlier position
adopted by FEMA during the TOPOFF exercises.19 As discussed later in this report,
it is debatable whether the Homeland Security Council’s broad interpretation is
supported by the text and legislative history of the Stafford Act.
Most recently, in March of 2007, FEMA issued a Disaster Assistance Policy
(DAP) that “establishes the types of emergency protective measures that are eligible
under the Public Assistance Program during a federal response to an outbreak of
human influenza pandemic.”20 It is unclear whether this DAP is a departure from
FEMA’s prior assertions that biological disasters were ineligible for major disaster
assistance. On one hand, the DAP states that it is “applicable to all major disasters
and emergencies declared on or after the date of publication” and cites as authority
the provisions of the Stafford Act authorizing major disaster assistance.21 However,
the only types of assistance offered by the DAP in the event of a flu pandemic are
Emergency Protective Measures (Category B) provided by FEMA’s Public
Assistance Program.22 Notably, Category B assistance may be offered during
emergency declarations, and is not limited to major disaster incidents.23 In fact,
Category B assistance was precisely the type of assistance authorized during the
emergency declarations for West Nile virus in 2000.24 Therefore, this DAP is not
necessarily inconsistent with the view that biological disasters are ineligible for major
disaster assistance. Other guidance issued by FEMA does not mention flu
pandemics, but may still be relevant. For example, the most recent working draft of

Pandemic Influenza, at [http://www.whitehouse.gov/homeland/nspi_implementation.pdf].

21 Id. However, this language and cited authority is not unique to this DAP and may simply
be boilerplate used by the drafters.
22 Category B assistance offers reimbursement to state or local entities for, among other
things, the purchase and distribution of medicine and other consumables; management,
control, and reduction of immediate threats to public health and safety; emergency medical
care and temporary medical facilities; communicating health and safety information to the
public; storage and internment of unidentified human remains; and recovery and disposal
of animal carcasses. Id.

the National Disaster Housing Strategy notes that quarantine and isolation facilities
may be necessary “to meet the demands of major or catastrophic disasters.”25
In summary, FEMA has historically excluded biological incidents from major
disaster declarations under the Stafford Act, but the current presidential policy
appears to consider biological incidents, or at least flu pandemics, to be eligible for
major disaster assistance. The permissibility of both interpretations in light of the
current statutory language is discussed below.
Recent Legislative Activity
A provision in S. 3721, introduced in the 109th Congress by Senator Collins of
Maine, would have added the following to the definition of a major disaster:
any act of domestic terrorism or international terrorism (as those terms are
defined in section 2331 of title 18, United States Code) [and] any outbreak of26
infectious disease, or any chemical release, in any part of the United States.
This provision would have made flu pandemics clearly eligible for major
disaster assistance, but it was not enacted. A number of other modifications to the
Stafford Act were ultimately added by the Post-Katrina Emergency Management
Reform Act of 2006,27 but no changes to the definition of a major disaster were made
by that law.
Under the standard procedure for a declaration under the Stafford Act, the
governor of an affected state submits a request for either an emergency or major
disaster declaration.28 The Federal Emergency Management Agency then evaluates
the incident and makes a recommendation to the President, with whom lies the
ultimate discretion to make a declaration.29 The Stafford Act precludes any judicial30
review of that decision. Therefore, even though “it is emphatically the province and

duty of the judicial department to say what the law is,”31 a requesting governor or
other affected party that disagrees with the executive’s interpretation of what
constitutes a major disaster is unlikely to be successful seeking a judicial remedy.
Denials of declaration requests may be appealed and resubmitted to the President,
but, again, there is no possibility of judicial review.32
Nevertheless, questions may arise among policymakers and other stakeholders
as to which of the dueling interpretations of the Stafford Act are legally permissible:
that is, whether the Stafford Act requires the conclusion that flu pandemics are either
eligible or ineligible for major disaster assistance. The validity of an executive
branch construction of a statute can be evaluated using the two-prong test laid out by
the Supreme Court in Chevron v. Natural Resources Defense Council.33 First, if the
text and legislative history of the statute demonstrate that Congress has spoken
directly on the issue, then that statutory language or history must control. However,
under the second prong, “if ... Congress has not directly addressed the precise
question at issue,” the agency’s interpretation will stand so long as it is a reasonable
one. 34
Both positions regarding the eligibility of flu pandemics for major disaster
assistance are evaluated below using this two-prong test. But, regardless of what
result the application of Supreme Court jurisprudence is likely to have in this case,
it is important to note that Congress may come to its own conclusions as to whether
a particular type of incident should or should not be considered a major disaster, and
may amend the statutory definition if it deems it appropriate to do so.
Ambiguity of Congressional Intent
The first prong of the Chevron test asks whether Congress has directly spoken
on the issue. If Congress has spoken, then the analysis ends, and the agency’s
interpretation must comport with that congressional intent. In this case, the inquiry
is whether the statutory text and legislative history of the Stafford Act demonstrate
that Congress addressed whether the definition of a major disaster includes a flu
Statutory Text. The statutory definition of a major disaster confines its scope
to “natural catastrophes ... or, regardless of cause, any fire, flood, or explosion.” A
flu pandemic is not a fire, flood, or explosion under the ordinary meaning of those

34 Id. Although this analysis uses a judicially created framework for evaluating an
interpretation of a statute by the executive branch, this should not be taken to mean that
FEMA or the President could be sued in state or federal court for failing to designate a flu
pandemic as a major disaster. This analysis is solely included to provide a context with
which policymakers and other stakeholders may view this issue.

three words. Therefore, a flu pandemic cannot qualify as a major disaster unless it
can be considered a natural catastrophe, as that term is defined for purposes of the
Stafford Act.
The text of the Stafford Act provides concrete examples of natural
catastrophes,35 but it does not appear to provide an exhaustive list of all qualifying
events.36 Based on a plain reading of the phrase, it is not clear whether a flu
pandemic would be considered a natural catastrophe. Neither the Stafford Act nor
any other provision of the U.S. Code provides a legal definition of a catastrophe.
Dictionary definitions of a catastrophe range from “a momentous tragic, usually
sudden, event marked by effects ranging from extreme misfortune to utter overthrow
or ruin”37 to a “sudden disaster, wide-spread, very fatal, or signal,”38 either of which
would seem to be applicable in the case of a flu pandemic. Additionally, many media
reports colloquially refer to a pandemic as a catastrophe.39 But, even though a
pandemic likely has the potential to cause sufficient harm to meet the ordinary
understanding of a catastrophe, the event would still need to be considered natural
in order to be eligible for major disaster assistance.
The Stafford Act does not elaborate on the meaning of natural, but various
dictionaries define it as “formed by nature; not subject to human intervention, not
artificial,”40 and “occurring in conformity with the ordinary course of nature.”41 As
has been recently observed with the H5N1 strain of avian influenza, it is possible for
virulent flu strains to develop without human intervention, and once infection occurs,
the virus can continue to propagate and spread absent human intervention by virtue
of the innate biological processes present in living persons. In response, one could
argue that the widespread dispersal of a flu pandemic is likely dependent upon human
Recent attention garnered by actual and potential biological terrorism attacks
raises the question whether an entirely man-made disease epidemic could be rightly
described as a natural catastrophe. Initially, one should note that it is not necessary
to conceptually view randomly occurring flu pandemics in the same category as

intentional biological attacks. However, even if one were to treat all biological
incidents as the same, other examples of known natural catastrophes are not
necessarily disqualified because they may be partially caused by human actions. For
example, landslides are statutorily identified as natural catastrophes,42 even though
human development may precipitate their occurrence.43
Textual arguments for excluding a flu pandemic from major disaster assistance
may also be made. One could conclude from the statutory definition that a flu
pandemic is not natural in the same way that a tornado or a hurricane is natural.
Ejusdem generis is a canon of construction stating that “when a general word or
phrase follows a list of specifics, the general word or phrase will be interpreted to
include only items of the same type as those listed.”44 Applying this canon of
construction, one interpretation is that the list following the phrase “natural
catastrophe” limits its scope to geologic or climatic events that have the potential to
cause extensive physical property damage. Furthermore, there is evidence that the
threat of infectious outbreaks was not alien to Congress, specifically in light of its
response to cholera and yellow fever during the latter half of the 19th century.45
Consequently, the omission of infectious diseases from the list of explicit natural
catastrophes bolsters the argument that outbreaks of infectious disease were seen by
Congress as distinct from natural catastrophes.
Legislative History. Insofar as the text of the major disaster definition is
susceptible to more than one interpretation, it may be helpful to examine the
legislative history to further interpolate Congress’s intent in drafting the provision.
The current definitions of emergencies and major disasters were enacted in 1988 with
passage of the Stafford Act. Prior to that, the definitions for both major disasters and
emergencies declarations were contained in the Disaster Relief Act of 1974 (Disaster
Relief Act), and had applied to
any hurricane, tornado, storm, flood, high water, wind-driven water, tidal wave,
tsunami, earthquake, volcanic eruption, landslide, mudslide, snowstorm, drought,46
fire, explosion, or other catastrophe.
Conspicuously, the pre-Stafford definitions did not limit emergency or major
disaster declarations to natural catastrophes. In 1980, a review of past emergency

43 See FEMA, Landslide and Debris Flow (Mudslide), available at

“steepening of slopes caused by erosion or human modification”).
44 See CRS Report 97-589, Statutory Interpretation: General Principles and Recent Trends,
by Yule Kim, at n.49 and accompanying text. In this case, the general phrase “any natural
catastrophe” actually precedes the list of specific examples, but the same interpretive
principle applies.

emergencies and major disasters were primarily distinguished by the severity of the incident.

and major disaster declarations found that “Presidential authority to extend disaster
assistance has been exercised almost exclusively in cases where damage was caused
by or was closely related to some act of nature.”47 However, it appears likely that the
amended definitions in the Stafford Act, which limited major disasters to natural
catastrophes and created a new definition for emergencies, were partly enacted in
response to the presidential use of the Disaster Relief Act authority to deal with
certain man-made incidents.48
For example, in 1980, a large number of people fled Cuba and arrived in
southern Florida. President Carter directed FEMA to provide temporary housing and
shelter for these refugees, apparently under the authority of the Disaster Relief Act.49
Also in 1980, FEMA assisted with the temporary relocation of families affected by
the toxic waste deposits in the Love Canal neighborhood of Niagara Falls, New
York.50 Similarly, in 1983, FEMA assisted with the relocation of residents of Times
Beach, Missouri, after the area had been contaminated with dioxin.51 These incidents
generated controversy in Congress, which expressed concern that
in some instances aid has been extended by the President in situations which
resulted primarily, if not entirely, from human activity rather than natural
hazards.... Broadening the scope of the [Disaster Relief] Act to cover both
natural and non-natural catastrophes has strained the capacity of programs52
designed to respond only to natural catastrophes.
Following these declarations, an amendment to the definition of both
emergencies and major disasters under the Disaster Relief Act was proposed, limiting
such declarations to “physical or natural catastrophe[s].”53 Although this amendment
was not enacted, the debate regarding the amendment suggested that a chemical spill

would have been considered a physical catastrophe, but not a natural one.54 Further
attempts to amend the definitions of major disasters and emergencies were
introduced several times during the 1980s and permitted only “natural catastrophes.”
The definition was ultimately successfully amended by the 100th Congress as part of
the passage of the Stafford Act in 1988.
An examination of this legislative history reaffirms the conclusion that the 100th
Congress’s principal intent in limiting major disaster assistance to “natural” incidents
was to deny major disaster assistance to incidents that were caused by human
activity. Furthermore, the legislative history provides at least two clear examples of
Presidential declarations for which Congress likely found natural causes lacking: the
mass arrival of political refugees and instances of chemical contamination.
Nevertheless, it is likely inaccurate to say that by excluding these two types of
incidents from major disaster assistance Congress clearly addressed the issue of flu
pandemics or other biological incidents under the Stafford Act.
Reasonableness of Executive Branch Interpretations
The preceding analysis of the text and legislative history indicates that Congress
did not directly address whether a flu pandemic is a natural catastrophe for purposes
of the Stafford Act. Under the framework laid out by the Supreme Court in Chevron,
the remaining question is whether a particular executive branch interpretation is “a
reasonable choice within a gap left open by Congress.”55
In this case, interpreting a flu pandemic as either a natural or non-natural
catastrophe is arguably reasonable. On the one hand, the manner in which a flu
pandemic is likely to propagate does not require human intervention. Making flu
pandemics eligible for major disasters makes the maximum amount of resources
available to avert the loss of life, human suffering, and loss of income that is likely
to occur in the event of a flu pandemic. Some types of assistance that are only
available in a major disaster declaration may be particularly useful in a flu pandemic.
For instance, a flu pandemic is likely to result in a significantly reduced workforce
as victims fall ill and others stay home to take care of them. The provision of
unemployment assistance and emergency public transportation under the Stafford Act
both may be an appropriate response, but are only available under a major disaster
On the other hand, a pandemic is substantially different than the climatic and
geologic natural catastrophes listed by the Stafford Act, and many types of major
disaster provisions, such as assistance to repair buildings or clear debris, are not
likely to be necessary during a flu pandemic. Restricting flu pandemics to only
emergency assistance arguably limits the burden on federal disaster relief funds.
Additionally, other federal responses may be more appropriate to deal with a
pandemic, such as the authority of the HHS Secretary to declare a public health

54 S.Rept. 96-891 at 3 (1980).
55 Chevron, 467 U.S. at 866.

emergency,56 or impromptu legislation to provide assistance with respect to a
particular incident.
Finally, it should be noted that the reasonableness of either interpretation is
being evaluated under current law. Were Congress to conclude that flu pandemics
categorically should or should not be eligible for major disaster assistance, it may
amend the statute to explicitly say so. In that case, the clearly expressed intent of
Congress would render any evaluation of an executive branch interpretation
unnecessary, and Congress’s intent would control.
