National Response System (NRS)
The National Oil and Hazardous Substances Response System (NRS) operates under the National Oil and Hazardous Substances Pollution Contingency Plan (NCP).
The NRS is a critical component of the broader and overarching NRF that is administered by the Department of Homeland Security (DHS) It is used to coordinate responses to oil spills and releases of hazardous substances. It is designed to ensure that incidents are managed quickly, effectively, and in a coordinated manner to protect workers, the public, and the environment.
The National Response System (NRS) is established and supported by federal law. These laws define the government’s authority and responsibilities for responding to oil spills and releases of hazardous substances that threaten public health, worker safety, or the environment.
The primary laws that form the legal foundation of the NRS include:
-
Section 311 of the Clean Water Act (CWA) , as amended by the Oil Pollution Act (OPA) of 1990
This law provides federal authority to prevent, respond to, and clean up oil discharges into navigable waters and adjoining shorelines. The Oil Pollution Act strengthened response requirements following major oil spills by expanding federal response authority, increasing liability for responsible parties, and improving preparedness and planning requirements. The CWA/OPA focuses specifically on oil spills and petroleum products.
-
Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA)
Commonly known as the Superfund law, CERCLA establishes federal authority to respond to releases or threatened releases of hazardous substances, pollutants, and contaminants. CERCLA excludes petroleum products but covers a wide range of toxic chemicals. It also provides funding mechanisms for cleanup when responsible parties cannot be identified or are unable to pay.
The NRS is divided into local, regional, and national organizational levels. Participants include federal, state, local, tribal, and private sector agencies and organizations. This coordinated approach allows resources, expertise, and equipment to be shared across jurisdictions during an emergency.
National Response Team (NRT)
The National Response Team (NRT) is an organization of 15 Federal departments and agencies responsible for coordinating emergency preparedness and response to oil and hazardous substance pollution incidents. The Environment Protection Agency (EPA) and the U.S. Coast Guard (USCG) serve as Chair and Vice Chair respectively. The National Oil and Hazardous Substances Pollution Contingency Plan (NCP) and the Code of Federal Regulations (40 CFR part 300) outline the role of the NRT and Regional Response Teams (RRTs). The response teams are also cited in various federal statutes, including Superfund Amendments and Reauthorization Act (SARA) – Title III and the Hazardous Materials Transportation Act (HMTA).
The NRT is also involved in recovery efforts following major incidents, helping agencies assess environmental impacts and coordinate long-term cleanup activities. Its role extends to incidents involving weapons of mass destruction, as well as natural and technological disasters that have environmental consequences.
This structure ensures coordinated response from notification through cleanup, with EPA and USCG as primary federal leads depending on the incident location. Local/state/tribal responders are integrated at all levels via Unified Command.
