From the Introduction: "This FIOP [Federal Interagency Operational Plan] builds upon the National Response Framework (NRF), which sets the strategy and doctrine for how the whole community builds, sustains, and delivers the Response core capabilities identified in the National Preparedness Goal. This FIOP describes the concept of operations for integrating and synchronizing existing national-level Federal capabilities to support local, state, tribal, territorial, insular area, and Federal plans, and is supported by Federal department-level operational plans, where appropriate. The concept of operations and supporting tasks contained in the Response FIOP are scalable, flexible, and adaptable, allowing the FIOP to be used regardless of cause, size, location, or complexity. Concepts of operations and/or tasks may be modified, added, or deleted depending upon the incident. […] This FIOP describes how the Federal Government delivers core capabilities for the Response mission area. Specifically, the Response FIOP is an all-hazards plan that describes how the Federal Government, pursuant to the Robert T. Stafford Disaster Relief and Emergency Assistance Act (Stafford Act) or other appropriate non-Stafford Act legal authority, supports local, state, tribal, territorial, and insular area efforts to save lives, protect property and the environment, and meet basic human needs following an emergency or disaster. The Response FIOP outlines delivery of Federal support to address the impacts of natural disasters or other emergencies."
