Natural resources at Portland Harbor, including water, fish, and wildlife are held in trust for all people. Responsibility for protecting these resources is shared among Trustees: specific federal and state agencies and tribes. When natural resources are injured by releases of hazardous substances or oil, federal laws empower the Trustees to obtain compensation and restore the injured resources and their habitats. This process is called natural resource damage assessment (NRDA). NRDA is separate from the cleanup process at the Portland Harbor Superfund Site, which is led by the EPA. The Portland Harbor Natural Resource Trustee Council website provides information on the Trustee Council, the damage assessment process, and how restoration activities are benefiting natural resources and the public.
