Portland Harbor
NPL SitePortland, OR
According to the EPA Superfund Enterprise Management System, Portland Harbor in Portland, OR is listed with NPL status NPL Site. Its Hazard Ranking System (HRS) score is 50.00. The public extract catalogs 259 contaminant records for this site. NPL listing is a cleanup-authority designation, not a measured health-risk score.
Superfund National Priorities List inclusion (status and HRS score shown above) is the EPA's formal designation that a contaminated site qualifies for long-term federal cleanup authority under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). A federal-facility classification means the site is owned or operated by a federal agency, which routes cleanup responsibility differently than a privately owned site.
"Construction Complete" (status shown above) is an EPA milestone marking that the physical remedy work is finished, not that the site has exited EPA oversight; long-term monitoring can continue afterward. Deletion from the NPL is a separate, later step the EPA takes only once it determines every planned response action is finished.
NPL listing is a cleanup-authority designation in the EPA record, not a quantitative health-risk score. HRS scores of 28.50 or above qualify a site for the NPL under the EPA screening model (toxicity, pathways, waste quantity, and affected population factors). For current site conditions and official community notices, see the EPA Regional Superfund profile and the Oregon environmental agency.

Frequently Asked Questions
What is the Portland Harbor Superfund site? ▼
Portland Harbor is an active National Priorities List (NPL) Superfund site located in Portland, OR. It has a Hazard Ranking System (HRS) score of 50.00 (rank #11 of 21 scored Oregon sites). Superfund sites are contaminated locations identified by the EPA for long-term cleanup under CERCLA.
What does NPL listing mean for Portland Harbor? ▼
According to the EPA, National Priorities List (NPL) listing designates a site for long-term federal Superfund cleanup authority. It is a programmatic status in the Superfund Enterprise Management System, not a quantitative health-risk score for nearby residents. Construction-complete status is not marked in the EPA record for this site. Site-specific conditions and community guidance are published by EPA Regional Superfund offices and the relevant state environmental agency.
What is the HRS score for Portland Harbor? ▼
Portland Harbor's Hazard Ranking System (HRS) score is 50.00, placing it #11 of 21 Oregon Superfund sites with a scored HRS evaluation. Sites with a score of 28.50 or greater qualify for the NPL; the model weighs contaminant toxicity, waste quantity, release likelihood, and affected population, and is not a community health diagnosis.
What contaminants are at the Portland Harbor site? ▼
The EPA public Superfund extract catalogs 259 contaminants at Portland Harbor, documented through the remedial investigation process. Counts reflect listed records in that extract, not a complete inventory of every substance ever present.
What is the cleanup status of Portland Harbor? ▼
Portland Harbor is currently NPL Site on the National Priorities List. The EPA Superfund cleanup process includes phases from preliminary assessment through post-construction completion.
NPL listing is a cleanup-authority designation in the EPA record, not a quantitative health-risk score. See Superfund Sites Explained for how the National Priorities List, Hazard Ranking System, and cleanup phases work.
