T HE EMERGENCY OPERATIONS CENTER (EOC) IS A
generic tool for coordinating on-scene operations
during low-frequency and high-risk incidents. Every
community, large and small, faces the likelihood of an over-
whelming emergency event. Often, these incidents will lack a
common operating picture and can transcend political juris-
dictional boundaries. The ability of a community to acquire
and allocate necessary resources hinges on being prepared.
The roots of a community’s “all-hazard” preparedness program
involve intergovernmental relations and a detailed planning
process that includes mutual-aid assistance agreements. Em-
phasis must be on technical information based on an accurate
assessment of risk, vulnerability, and capabilities. Resources
will be scarce during a large-scale incident, and the EOC can
identify and obtain additional assets that are not always avail-
able to the on-scene incident commander (IC).
The EOC mobilizes people and equipment to handle
incidents that are outside the ability of any single agency to
resolve. The purpose of the EOC is to ensure that depart-
mental response capabilities are maintained and authoritative
information is disseminated to the general public. Capturing
important incident-related information at an EOC will provide
senior offi cials with data to set strategic directions; establish
priorities; allocate resources; and, under extreme circum-
stances, declare a disaster. These actions allow fi eld command-
ers to focus on the incident objectives while the EOC handles
supportive endeavors.
The EOC is an integral component of the larger Multiagency
Coordination System (MACS). The entire MACS consists of ini-
tial dispatch, on-scene command, coordination resource cen-
ters, coordination entities, and the EOC. Often, major incidents
require the activation of all components of the MACS during
the response and recovery phases. The establishment of an
EOC is a “time-tested” link in a stronger public safety system
when the use of critical resources requires decisive actions.
The EOC serves as a message center among the IC, elected
offi cials, and nearby jurisdictions. Under ideal conditions, the
EOC is centrally located where representatives from various
agencies can gather during an emergency. The EOC becomes
the pipeline of information for organizations that work behind
the scenes to protect the population at risk during a potential
disaster.
An important criterion for selecting an EOC is easy access
for agency representatives and elected offi cials. Large displays
assist in the transfer of critical information and create a com-
mon operating picture for organizations staffi ng the EOC.
TYPES OF EOCs Fixed Facility
The primary EOC is a central location usually found in an
existing multipurpose government building that will reduce
delays in the arrival of senior offi cials and staff personnel.
Usually the EOC is a permanent location with permanent
equipment. In addition to the main location, it is important for
fi nancial and logistical reasons to identify potential alternate
sites for reliability and suitability as part of an overall com-
munity risk management plan. It would be chaotic if, during
an emergency event, the center were damaged or had to be
evacuated. Local government should follow the federal govern-
ment guidelines that suggest a need for Continuity of Govern-
ment and Continuity of Operations (COOP). It should take no
longer than 12 hours to “ramp up,” or convert, a backup facil-

ity into a fully operable (hot) facility. All communities should
have a checklist for doing this.
Mobile EOC
The mobile EOC is used when a disaster is widespread
and there is an urgent need for a face-to-face briefi ng with
the incident management team (IMT) to reduce confusion.
The fl exibility of a mobile EOC allows for optimal interaction
between the IMT and the Policy Group when jointly review-
ing critical information. A tractor-trailer-style vehicle offers a
degree of comfort and a full communications center with soft-
ware that can tie together radio frequencies. Vehicles should
have linkage to the Internet, and most have a security camera
system that monitors all six sides. The mobile EOC allows
for planning from various locations and can provide valuable
insight for executive decision makers in a stable situation with
short-term recovery challenges.
Virtual EOC
This innovative concept has combined with “next-technolo-
gy” to replace the traditional “brick-and-mortar” EOC facility. A
virtual EOC is a state-of-the-art emergency management solu-
tion that exists solely or partially in cyberspace with private
networks and satellite communication. Remote locations will
reduce the refl ex time and limit vulnerability that exists when
all senior offi cials are assembled at a central location. With a
virtual EOC, authorized individuals have anytime, anywhere
access with a user name, password, and multiple secure server
with software application to a high-tech terminal that can
provide a higher-level knowledge of emergency management
principles. A technical specialist can be provided for a global
perspective on specifi c hazards and mitigation steps needed
in a local community. Smartphones, three-dimensional digital
blueprints to improve visualization features, make the visions
of yesterday today’s reality.
In any type of EOC, whenever a complex incident or wide-
spread disaster strikes a community, the efforts of traditional
and nontraditional fi rst responders [for example, a community
emergency response team (CERT) must be closely coordi-
nated and fully supported]. This is essential to managing the
numerous resources from different disciplines. The reporting
relationship between the EOC and the IC is important to avoid
confl icts, confusion, and duplication of efforts on the front
line. The staff at an EOC will need different competencies
based on the kind of damage or destruction caused by a man-
made or natural disaster. After-action reports from major inci-
dents clearly reveal that local resources will be overwhelmed
and will require external assistance. History has shown that
there can be a serious disconnect between the IC and the EOC
when a joint planning process is not practiced. The EOC will
fail in its unique mission without adequate and accurate infor-
mation. The EOC staff and the IC need suffi cient time to create
a meaningful plan of action based on factual data. The EOC
is responsible for organizations’ working together and being
aware of one another’s mission.
Just as the IC needs a stationary incident command post
(ICP) for effectiveness at the emergency scene, a single EOC
facility that is well-designed and suffi ciently staffed will im-
prove coordination and support endeavors. Any major emer-
gency situation can cause large losses. A partnership between
the EOC and the IC will protect lives and property and will
minimize the impact of response and recovery problems.
ESSENTIAL FUNCTIONS OF THE EOC The EOC depends on maintaining situational awareness.
Planning enables agencies’ representatives to focus on vital
services to maintain the safety and well-being of the public at
risk. The proper time to develop and practice an emergency
operation plan (EOP) is before a community suffers a high-
risk/low-frequency incident. Document the following essential
functions during EOC activation to ensure a fair distribution of
resources:
• Damage assessment reports.
• Resources, acquired and used.
• Media and public requests for assistance.
• Accounting of public safety expenses.
• Response plan for providing evacuation and sheltering.
• Support services for food, water, ice, and utilities.
• Incident log (ICS #214) form.
ORGANIZATIONAL STRUCTURE OF THE EOC EOCs exist in many forms, and there is no single organi-
zational structure that is correct for all jurisdictions. The key
is to maximize the staff’s efforts and allow decision making
at the lowest practical level. Presidential Directive #5, which
outlines “Command and Management” procedures, does not
mandate that any community adopt any particular model as its
organizational structure. However, in the future, federal grant
money may be linked to the specifi c way an EOC is organized.
An EOC should be organized with the intent of facilitating a
smooth operation with data collection, documentation, and ex-
ecutive decision making to maintain public confi dence under
ever-changing conditions while acting on routine, priority, and
classifi ed information.
The local government is entirely responsible for the
management of emergency activities within its jurisdictional
boundaries. Response priorities will focus on getting the right
resources to the right place at the right time. This promotes
total uniqueness in the concept of operations at local and state
EOCs.
Typically, there are four ways to organize an EOC facility.
Each has some recognized coordination and support challenges.
Over time, many jurisdictions have used these structures very
successfully.
1. Major Management Activities Structure
Policy Group—comprised of “high-level” elected offi cials
and department heads who focus on the overall objectives
and priorities of the community. Decisions made by the Policy
Group set the direction for implementation by the Coordina-
tion, Resource, and Operations Groups.
Coordination Group—personnel responsible for collecting
and analyzing data, including advanced predictions based on
the essential functions of damage, resource allocation, public

information, and expenditures that an EOC must gather.
Resource Group—comprised of representatives from agen-
cies or organizations that provide or could be asked to supply
resources to the scene. These organizations may include trans-
portation agencies, utility companies, business and industry
representatives, and mutual-aid partners.
Emergency Management Operations Group—representa-
tives from any agency with responsibility for any portion of
the response or recovery. Units within this group are dictated
by the specifi c incident for a tactical assignment, including law
enforcement, fi re, public works, emergency medical services,
and numerous other agencies.
The advantage of this model is that the organizational
structure is relatively simple, with straight lines of communica-
tion and chain of command. With this model, all key problem
solvers and representatives from participating agencies can
contribute to decision making and resource allocation.
The disadvantage of this model is the linkages with on-
scene commanders. There is not a one-to-one match between
the organization of the on-scene incident command structure
and the EOC organization.
2. Incident Command System (ICS) Structure
The EOC’s emergency program manager or designee fi lls
the top position. The EOC commander serves a similar role
as the Policy Group and makes executive decisions that
establish the overall objectives “concept of operation” at the
EOC. Often under this format, the emergency program man-
ager is viewed as the EOC commander. This military-style
command structure can increase the interaction and provides
a heightened level of situational awareness.
Emergency Management Operations is responsible for
coordinating with and supporting on-scene responders. Posi-
tion titles of branches, divisions, and groups are organized as
necessary to support the incident.
Emergency Management Planning is responsible for gather-
ing and analyzing information and informing decision makers
of changes in the use of resources. A technical specialist may
be used to provide special insight and expertise.
Emergency Management Logistics serves as the single order-
ing point from the ICP. Coordinating the network of primary
and backup communications equipment will assist in any large-
scale incident, but it is especially meaningful during an evacua-
tion or reentry with special transportation and housing needs.
Emergency Management Finance/Administration is respon-
sible for designing fi nancial projections.
The advantage of this model is the clarity of roles and func-
tional integrity, which leads to a clear contact point between
the IC and the EOC. The coordination and support of logistical
and fi nancial duties will relieve the workload at the incident
scene and dispatch center.
The disadvantage of this model is the potential for confusion
about authority at the incident scene vs. in the EOC facility.
3. Emergency Service Functions (ESF) Structure
An operation manager is in charge of the EOC. The Opera-
tion area can include branches such as fi refi ghting, public
works/emergency engineering, public health and medical
service, urban search and rescue, mass care, and law enforce-
ment. Currently, there are 15 branches under the National
Response Framework (NRF).
The Planning area includes situation analysis, documenta-
tion, advanced planning, technical services, damage assess-
ment, resources status, and geographic information system
technology. The Logistics area includes a service and support
branch.
The Finance/Administration area includes compensation
claims; purchasing/procurement; cost concerns; timesheets
for personnel; and disaster fi nancial assistance based on legal
records such as contracts, accounting records, and property
management photos.
The advantage of this model is that it appeals to local and
state EOCs because there is a clear one-to-one relationship
with the NRF as well as with on-scene ICS organizations.
The disadvantage is that local and state EOCs may not cor-
respond directly at the Operations level with the federal ESFs.
This potential misunderstanding with the ICS positions in the
on-scene Operation Section is a serious drawback and neces-
sitates an enormous amount of additional training to ensure
that the agencies responsible for ESFs are able to competently
perform their assigned duties.
4. Multiagency Coordination (MAC) Group Structure
A MAC Group is made up of organization, agency, or
jurisdiction representatives who are authorized to commit
resources and funds. The success of the MAC Group depends
on its current membership. Sometimes membership is obvi-
ous by the organizations that are directly impacted and have
a resources commitment to an incident. Often, organizations
that should be members of a MAC Group are less obvious.
These organizations may include the local Chamber of Com-
merce, volunteer groups, the Salvation Army, the American
Red Cross, faith-based charities, and other organizations with
special expertise or knowledge. These groups may not have
“hard” resources or funds to contribute in the response and

During an incident, most workers remember
what they practiced instead of what they
were told or have read.

recovery phase, yet their contacts, political infl uence, and
technical expertise are the foundation for a collaborative ef-
fort.
The MAC Group coordinator is an optional position that
provides supervision to the various components. Members of
the MAC Group directly distribute the result of their delibera-
tion to their own organizations as well as through the chain of
command (MAC entities, dispatch centers).
The MAC Group Situation Assessment Unit collects and as-
sembles information needed for the MAC Group to fulfi ll its
role. At times, a MAC Group Resource Status Information Unit
will gather information on the status of resources.
The Joint Information Center ( JIC) is a public informa-
tion unit that has access to local information sources and
governmental entities and is responsible for coordinating
a summary report. Public information must be organized
around a Joint Information System that is overseen by pub-
lic information offi cers. Intelligence information is routed
from the EOC to the JIC for collection, validation, and pub-
lic dissemination.
The advantage of this model is that it works well to ensure
coordination among other MAC entities. It is useful as a
mechanism where no system exists to provide short-term mul-
tiagency coordination and decision making. Typically, a MAC
Group fi ts into a policymaking part of an existing EOC.
Some of the more common MAC Group applications include
the following:
• A single jurisdiction may establish a MAC group as part
of its EOC function. In this application, it is important
that the jurisdiction broadly defi ne its role because of
the impact on other agencies and organizations.
• MAC Groups are frequently defi ned geographically, espe-
cially when an emergency crosses jurisdictional boundar-
ies.
• A MAC Group may be organized functionally. For exam-
ple, law enforcement agencies at local, state, and federal
levels may establish a MAC Group to assist in coordinating
a response to a major terrorist activity.
• A MAC Group may be organized nationally. For example,
during wildfi re season, a National MAC Group convenes
at the National Interagency Fire Center in Boise, Idaho.
This MAC Group includes representatives from the federal
wildland fi re agencies, the states, the Federal Emergency
Management Agency, and the military.
The disadvantage of this model is a lack of clearly defi ned,
standardized relationships to other MAC entities. There is no
associated implementation of staffs, and it rarely is used as a
stand-alone structure in an EOC. A “generic” MAC component
can be used at any level of government.
CHARACTERISTICS OF AN EFFECTIVE ORGANIZATION
How information is used will affect how the information
is managed. Being prepared means there is no substitute for
planning, training, and exercising. Individuals are not very
good at tasks they do not do often. Job aids, checklists, and
cross-training will ensure that the essential functions of an
EOC will be documented even with the smallest staff.
Training is a key element once the standard operating
guideline and EOP are written. It has been repeatedly shown
that during an incident, most workers remember what they
practiced instead of what they were told or have read. This is
especially true where decision making and practical prob-
lem solving can get intense. Without an understanding of the
situation and regular practice, panic can set in, and even the
simplest task can become diffi cult to remember. Maintaining
sustainable skills in the data collection, documentation, and
parameters for decision making during an EOC activation is
critical for safety and effectiveness. Personnel changes, reor-
ganizations, and downsizing can have a dramatic effect on job
performance. A yearly orientation with periodic tabletop and
full-scale exercises all have value in reinforcing essential func-
tions and duties at an EOC.
Communication is the “lifeblood” at any incident. A com-
munications network of “talk paths” and shared radio channels
will enhance responders’ ability to transfer information among
various private and public agencies. Determining the scope of
the disaster is possible only when fi rst responders in the fi eld
accurately report conditions to the appropriate EOC represen-
tatives so that positive actions can be taken.
The EOC is the hub for communication. Incident informa-
tion, with a clear message fl ow and recording system, must
be shared within the EOC, between the EOC and the ICP, be-
tween the EOC and the general public, and between commu-
nity-elected offi cials and other jurisdictions.
The EOC is the key to minimizing any confl ict, confusion,
and duplication during the response or recovery phases of
a large-scale incident. By having high-level decision makers
located together, there is a greater chance that all resources
will be safely used to a maximum level of effi ciency. The
EOC’s coordination and support will assist the on-scene
commanders in accomplishing strategic and tactical activi-
ties.
Communication among the various response partners from
the local to the national level is described as one of the most
challenging aspects during any emergency. To save lives and
protect priorities, there must be a seamless fl ow of two-way
communication between the ICP and the EOC. Today is the
day to start improving standard operating policies, updating
emergency concepts of operation plans, and formulating a
positive working relationship with your numerous partners in
command, management, and preparedness. ●
