The National Response Framework and Emergency Suppport Function

Emergency Support FunctionUSACE is the lead agency for ESF #3, Public Works & Engineering; we are FEMA’s Engineer.  Our pre-scripted standard mission sets include Debris Removal and Clearance, Temporary Emergency Power, Temporary Housing and Critical Public Facilities (CPF), Temporary Roofing, Infrastructure Assessment, Urban Search and Rescue Structural Specialists.  The Corps also lends trained personnel to support other ESFs, such as ESF #9, Urban Search and Rescue, when FEMA activates them.

Upon State request, FEMA tasks USACE to execute these missions through Mission Assignments.  We also perform, as requested, engineering missions that fit our core capabilities but do not fall under the above pre-scripted mission assignments.

What is the Stafford Act? What is the
Stafford Act?

The Robert T. Stafford Disaster Relief and Emergency Assistance Act, 42 U.S.C. 5121-5207 governs how the United States government provides a coordinated national response to disasters.  Stafford Act disasters are declared by the President for incidents that are of sufficient severity to warrant federal assistance to state, territorial, or tribal governments to alleviate damage and loss caused by the event. Such incidents may include natural catastrophes, or regardless of cause, fires, floods, or explosions.  Stafford Act incidents are eligible for programs available through the Act, which are funded by the Disaster Relief Fund (DRF).

Sections 402 and 502 of the Stafford Act give the President the authority to “direct any Federal agency, with or without reimbursement, to utilize its authorities and the resources granted to it under Federal law” (42 U.S.C. § 5170a(1)) in support of SLTTs and insular area response and recovery efforts for emergencies and major disasters. The Mission Assignment (MA) program is the mechanism through which FEMA executes this authority.

What is the National Response Framework? What is the
National Response Framework?

The National Response Framework (NRF) is a guide to how the Nation responds to all types of disasters and emergencies.  It is built on scalable, flexible, and adaptable concepts identified in the National Incident Management System to align key roles and responsibilities across the Nation.  The Stafford Act gives FEMA the lead, with help from contributing agencies, while the NRF assigns specific roles and responsibilities to each of these federal agencies.  These designations are called Emergency Support Functions, or ESFs. USACE is the lead agency for ESF #3, Public Works and Engineering.
