National Response Plan
The NRP "specifies how the resources of the Federal Government will work in concert with State, local, and tribal governments and the private sector to respond to Incidents of National Significance. The NRP is predicated on the National Incident Management System, or NIMS [released March 2004]. Together the NRP and the NIMS provide a nationwide template for working together to prevent or respond to threats and incidents regardless of cause, size, or complexity." 
"The National Response Plan establishes a comprehensive all-hazards approach to enhance the ability of the United States to manage domestic incidents. The plan incorporates best practices and procedures from incident management disciplines—homeland security, emergency management, law enforcement, firefighting, public works, public health, responder and recovery worker health and safety, emergency medical services, and the private sector—and integrates them into a unified structure. It forms the basis of how the federal government coordinates with state, local, and tribal governments and the private sector during incidents. It establishes protocols to help 
- "Save lives and protect the health and safety of the public, responders, and recovery workers;
- "Ensure security of the homeland;
- "Prevent an imminent incident, including acts of terrorism, from occurring;
- "Protect and restore critical infrastructure and key resources;
- "Conduct law enforcement investigations to resolve the incident, apprehend the perpetrators, and collect and preserve evidence for prosecution and/or attribution;
- "Protect property and mitigate damages and impacts to individuals, communities, and the environment; and
- "Facilitate recovery of individuals, families, businesses, governments, and the environment."
