The Department of Energy serves a Natural Resource Trustee over natural resources under its jurisdiction, custody or control.

The NRD program objectives are to identify the extent of injuries to natural resources and then to compensate the public for those lost resources or services. The injuries may be caused by direct or indirect releases of hazardous substances. See:

A Natural Resource Damage Assessment (NRDA) is the process of collecting, compiling, and analyzing information, statistics, or data through prescribed methodologies to determine damages for injuries to natural resources. At DOE sites, this process is best accomplished in collaboration with fellow federal, state, and tribal trustees. Natural resource trustees are charged with enforcing CERCLA’s NRD provisions on the public’s behalf. 

In addition to serving as a natural resource trustee, DOE is also a Potentially Responsible Party (PRP). A PRP is an entity believed to have liability for response costs and/or natural resource damages, under the law, for a CERCLA release. 


Injuries to natural resources are evaluated in the NRDA process by identifying the functions or “services” provided by the resources that were damaged by the contamination. This is a collaborative process among trustees. After identifying the impacted services, the baseline levels of services are determined and used to quantify the extent to which those service were lost. The quantified injuries are used to determine the damages to be paid by the PRP. This includes the cost of restoring, rehabilitating, replacing, or acquiring the equivalent of, the damaged natural resources; the diminution in value of those natural resources pending restoration; plus the reasonable costs of assessing those damages (33 U.S.C. § 2706(d)(1)).

Examples may include but are not limited to the restoration of impacted habitat productivity or species diversity, and access agreements to facilitate use of cultural resources.


CERCLA and the NCP create three categories of natural resource trustees:

  1. Federal trustees, who are designated by virtue of land management responsibility or to act as trustee for specific resources (e.g., DOE is a trustee for all natural resources found on, under or above land that is managed by DOE);
  2.  State trustees, who are designated by the governor of each state; and
  3.  Tribal trustees, who are trustees for any natural resources owned, managed, controlled by or held in trust for the benefit of the tribe.

Trusteeship often overlaps, which requires a coordinated implementation effort among the trustees. For example, DOE and the Department of the Interior (DOI) both have trust responsibilities for endangered species located on DOE-managed land. Depending on the species and state law, the state and/or a tribe may have trust responsibility for the same resource as well.


NRD restoration actions typically follow environmental cleanup actions.  However, finding opportunities to integrate restoration into cleanup where possible can proactively restore lost environmental services and even reduce the future cost of NRD settlements. Integration also provides opportunities to streamline data collection and analysis and leverage mobilized cleanup contractors to perform NRD restoration activities.

The NRD program operates under DOE Policy 140.1, Natural Resource Damage Assessment Cooperation and Integration, and shares information across the complex to facilitate the expeditious and cost-effective assessment of damages and restoration of natural resources at DOE sites.
