Western Port Angeles Harbor

Public review of the draft Remedial Investigation/Feasibility Study and draft Amendment to Agreed Order

Jan. 16, 2020 - March 16, 2020, 11:59 p.m.

We invite your comments on cleanup documents regarding the Western Port Angeles Harbor Sediment Cleanup Unit.

The Western Port Angeles Harbor Sediment Cleanup Unit is approximately 1,160 acres located in the harbor from the Port Angeles' downtown commercial/industrial area to Ediz Hook.

  • Draft Remedial Investigation/Feasibility Study (RI/FS) Part 1 and Part 2 (Appendices). The Remedial Investigation identifies contaminants, measures how much there are, and where they are located. The Feasibility Study proposes several cleanup options for cleanup of contaminated sediment in the western part of Port Angeles Harbor.
  • Draft Amendment to Agreed Order DE9781. This document is an addition to an agreed order and it calls for preparation of a preliminary draft cleanup action plan.
  • A fact sheet briefly summarizes these documents.

The remedial investigation shows that sediment contaminants in the western harbor include metals, dioxins/furans, polychlorinated biphenyls (PCBs), and carcinogenic polycyclic aromatic hydrocarbons (dPAHs).

People, pets, or wildlife that physically contact or accidentally ingest contaminated sediment, or eat contaminated fish and shellfish may be exposed to hazardous chemicals.

Cleanup options described in the feasibility study prevent these exposure pathways. Options for sediment cleanup include dredging, capping and containment, placing clean sand/gravel on top of the contaminated sediments, and checking for natural deposition of cleaner material on top of contaminated sediments.

Background

Past industrial operations generated liquid waste and released it directly into the harbor and lagoon. Contaminated stormwater was discharged into the harbor. Several pulp and lumber mills burned salt-laden wood debris as a fuel source. Burning this debris formed hazardous substances, like dioxins, that rose up through smokestacks and settled out onto marine sediments.
