Entity Name



1.1 What is the data in the submission?

Mission Assignment, as defined in the 44 Code of Federal Regulations, is a work order issued by FEMA to another Federal agency directing completion of a specified task and citing funding, other managerial controls, and guidance.

Mission Assignments are essential and powerful tools for federal emergency management under the Stafford Act. Mission Assignments are distinct because they allow for deployment, employment and assistance from the full range of federal resources to support disaster needs.

1.2 Why does FEMA Issue Mission Assignments?

FEMA issues mission assignments in anticipation of, or in response to, a Presidential declaration of an emergency or major disaster. The Robert T. Stafford Disaster Relief and Emergency Assistance Act (Stafford Act) authorizes Mission Assignments.

When States, Tribes, or Territories are overwhelmed by disaster impacts, FEMA can fulfill requests for Federal assistance through a Mission Assignment. Mission Assignments are provided as a sourcing mechanism to direct and reimburse Other Federal Agencies for utilizing their capabilities to support disaster operations. Reimbursement of eligible expenditures are detailed in 44 Code of Federal Regulations 206.8 (c).

1.3 How are Mission Assignments Created?

Mission Assignments are administered, created and obligated, using DRF appropriations, as electronic forms within FEMA's financial systems. Each mission assignment includes essential information required to direct other Federal Agencies to support and fulfill disaster needs, such as cost estimates, location of need, requestor, statement of work and period of performance. Mission Assignments can be amended to reflect the tempo of disaster activities, by changing period of performance dates, increasing and decreasing the costs required to complete the work, or recouping dollars based on early work completion or cancellation. This process of financially managing DRF dollars is an ongoing process that takes place before, during and after disaster activities have ended. Initial mission assignment obligation amounts do not reflect true costs incurred after billing and reimbursement.

This data set contains information required as part of Congressional bill - the Sandy Recovery Improvement Act of 2013, and The Disaster Recovery Reform Act of 2019. FEMA is providing the following information for stakeholders:

  • State or Tribal Government
  • Disaster Number
  • Description of Disaster
  • Agency
  • Request for Assistance
  • Obligations/Estimate
  • Date Obligated
  • Percentage of Cost for which the State or Tribal Government is responsible (the cost share)

1.4 How is the data generated?

The data is derived from the National Emergency Management Information System (NEMIS). The system has been used since 1998 to process all mission assignments for FEMA's Mission Assignment (MA) program as the system of record. The dataset was extracted using FEMA's Enterprise Data Warehouse to ensure reliable, uniform data.

1.5 How can the data be used?

The data provides information regarding mission assignments issued to other federal agencies in response to Stafford Act incidents.

Note: The disaster costs reflected are not actual they include inflated estimations to ensure resources are available to address actual and potential life-saving, life-sustaining, and or mission-critical needs. This dataset is not intended to be used for any official federal financial report and should not be considered an official federal report.

Citation: The agency's preferred citation for each dataset is included in its metadata. Users should also cite the date that data was accessed or retrieved from and/or Finally, users must clearly state that 'FEMA and the Federal Government cannot vouch for the data or analyses derived from these data after the data have been retrieved from the Agency's website(s) and/or'
