Portland, OR
Portland Harbor is listed in the EPA Superfund Enterprise Management System with an NPL status of NPL Site and a Hazard Ranking System (HRS) score of 50.00. The site is located in Portland, OR. Superfund National Priorities List inclusion 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.
EPA Superfund records catalog 259 contaminants associated with this site, documented through the remedial investigation process. Construction of the cleanup remedy has not yet been designated as complete in the EPA record.
NPL listing does not, by itself, establish a health risk to nearby residents, it triggers federal authority to investigate, score, and remediate. HRS scores of 28.50 or above qualify a site for the NPL; the ranking weighs contaminant toxicity, release pathways, waste quantity, and affected population. For current site conditions and community health guidance, contact the Oregon environmental or health agency and the EPA Regional Superfund office listed on the official site profile.

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. Superfund sites are contaminated locations identified by the EPA for long-term cleanup.
Is Portland Harbor dangerous to live near? ▼
The presence of a site on the EPA National Priorities List does not by itself indicate an immediate health risk to nearby residents. EPA evaluates sites through a comprehensive process including remedial investigation and risk assessment. Cleanup activities may still be ongoing. For site-specific health questions, contact your state environmental or health agency.
What is the HRS score for Portland Harbor? ▼
Portland Harbor has a Hazard Ranking System (HRS) score of 50.00. The HRS is the EPA's principal mechanism for evaluating Superfund sites, scores of 28.50 or greater qualify for the NPL. Higher scores indicate greater potential risk based on toxicity, waste quantity, release likelihood, and affected population.
What contaminants are at the Portland Harbor site? ▼
The EPA has identified 259 contaminants at Portland Harbor. Contaminant data is maintained in the EPA's Superfund database and is based on site investigations conducted during the remedial process.
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.
About Superfund
The National Priorities List (NPL) is the list of sites of national priority among the known releases or threatened releases of hazardous substances, pollutants, or contaminants throughout the United States. The NPL is intended primarily to guide the EPA in determining which sites warrant further investigation.
The Hazard Ranking System (HRS) score is the principal mechanism the EPA uses to evaluate sites for placement on the NPL. Sites with an HRS score of 28.50 or greater are eligible for the NPL. Higher scores indicate greater potential risk.
The EPA's Superfund cleanup process typically follows these phases: preliminary assessment, site inspection, NPL listing, remedial investigation/feasibility study, remedy selection, remedial design/action, construction completion, post-construction completion, and NPL deletion. Some sites remain on the NPL for decades.
PlainEnviro presents this data without advocacy framing. The presence of a site on the NPL does not by itself indicate an immediate health risk to nearby residents. For site-specific health questions, consult your local environmental or health agency.
