Natural Resource Damage Assessment (NRDA)

The Superfund law gives federal, state and Tribal Natural Resource Trustees the authority to seek compensation for damages to public natural resources caused by contamination. In 2002, the Portland Harbor Natural Resource Trustee Council formed to develop and coordinate damage assessment activities at Portland Harbor and to plan for restoration of natural resources through the Natural Resource Damage Assessment (NRDA) process. The NRDA process is separate from EPA cleanup activities.

Under NRDA, the Trustee Council will evaluate how the natural resources were harmed over the time that the area has been contaminated and will develop a restoration program to compensate for those losses.

The natural resources of concern in Portland Harbor include Pacific salmon, Pacific lamprey, white sturgeon, bald eagle and osprey.

The Natural Resource Trustees include:

  • National Oceanic and Atmospheric Administration/Fisheries
  • Department of Interior
  • Oregon Department of Fish and Wildlife
  • The Confederated Tribes of the Grand Ronde Community of Oregon
  • The Confederated Tribes of the Umatilla Indian Reservation
  • The Confederated Tribes of the Warm Springs Reservation of Oregon
  • The Confederated Tribes of the Siletz Indians
  • The Nez Perce Tribe
  • The Yakama Nation

The City of Portland is involved in natural resource restoration work in all of Portland’s watersheds, not just in Portland Harbor.
