The Robert T. Stafford Disaster Relief and Emergency Assistance Act (Stafford Act) (Public Law 100-707) is a United States federal law designed to bring an orderly and systemic means of federal natural disaster assistance for state and local governments in carrying out their responsibilities to aid citizens. Congress amended it by passing the Disaster Mitigation Act of 2000 (Public Law 106-390), and again in 2006 with the Pets Evacuation and Transportation Standards Act (Public Law 109-308).
