Homeland Security STRATEGIC RESEARCH ACTION PLAN 2016 2019 - EPA
Executive Summary
EPA’s Office of Research and Development’s (ORD) Homeland Security Research Program (HSRP)
aims to help increase the capabilities of EPA and communities to prepare for and respond to
chemical, biological, and radiological disasters. Enhancing these capabilities will lead to improved
resiliency of our nation to environmental catastrophes. Disasters resulting in environmental threats
to public health and the ecosystem may be manmade or naturally occurring incidents including,
for example, terrorist use of anthrax spores in 2001, the Deepwater Horizon oil spill in 2010, and
Hurricane Katrina in 2005.

The Homeland Security Strategic Research Action Plan, 2016–2019 (StRAP FY16–19) is a four-year
research strategy designed to meet the following objectives:

		 •    Improve water utilities’ abilities to prepare for and respond to incidents that threaten
			     public health; and
		 •    Advance EPA’s capabilities to respond to wide-area contamination incidents.

EPA’s homeland security research is organized into three topic areas that support these objectives:
(1) characterizing contamination and assessing exposure; (2) water system security and resilience;
and (3) remediating wide areas. Short- and long-term aims within the topics outline a strategy for
addressing the objectives.

HSRP carries out applied research that aims to deliver relevant and timely methods, tools, data, and
technologies to those who carry out EPA’s homeland security mission. To accomplish this aim, we
engage our Agency customers throughout the research life cycle – identifying scientific capability
gaps, performing research to address the gaps, and formulating and delivering the products that fill
the gaps.

HSRP scientific products will improve the resilience of water systems to terrorist attacks or other
manmade and natural disasters. Specifically, utilities will have improved tools and strategies
to manage contaminated systems and approaches to make these systems inherently resilient.
HSRP products also provide the EPA with systems-based approaches for site characterization, risk
assessment, and clean up, including waste management. Such information will help federal, state
and local decision makers select cost-effective, timely options while minimizing the impact to the
environment.

is evolving its program from strictly addressing

disasters.

HSRP supports EPA’s responsibilities to prepare
for and respond to acute disasters by conducting
short-term, applied scientific research. The base
of the program focuses on CBRN contamination
resulting from intentional or unintentional
incidents; however, the HSRP also works to find
multiple uses of its research by applying, when
appropriate, its products to gaps in EPA’s ability
to effectively respond to all hazards. Finally,
“all hazards” capability gaps exist that are not
addressed by HSRP’s core program. HSRP will

on that foundation.

Improving community resilience is especially
critical for populations that have greater ex-

The following Problem Statement and Program Vision guide the research program:

    Problem Statement
    Natural or manmade disasters often result in environmental pollution that can threaten the
    health of populations and the ecosystems and commerce on which they rely. The United
    States is regularly affected by natural disasters and industrial accidents. It is very difficult for
    communities to be resilient in the face of such acute environmental catastrophes, especially
    if scientifically sound information to make difficult decisions is not readily available.

    Program Vision
    EPA and communities, including water utilities, have the scientific tools they need to prepare
    for and respond to disasters, thereby helping communities achieve resilience to catastrophes.

Building on the 2012–2016
Research Program
The current HSRP builds on the 2012–2016
StRAP2 (U.S. EPA, 2012). StRAP FY12–16 intro-
duced the idea that EPA’s homeland security
responsibilities are comprised of interconnect-
ed systems of activities: actions taken for one
activity could impact, negatively or positively,
another activity. Thus, a “systems approach”3
requires consideration of these interdependen-
cies prior to making decisions and taking action.
This “systems” view is furthered in the StRAP
FY16-19 and continues to guide research so

 Systems approaches, including systems-based solutions, aim to understand a system in totality through analyzing its various
components while still understanding how these components interact. These approaches also aim to understand the system at
many levels. In this context, the “system” here is the incident response and recovery efforts composed of many interconnected
activities such as constructing a sampling strategy, selecting a cleanup technology, and managing wastes.
