We invite you to an open house where we will present information and answer questions about planning cleanup of the Western Port Angeles Harbor Sediment Unit.
Information from the draft Remedial Investigation/Feasibility Study (RI/FS) (Part 1 and Part 2), draft amendment to Agreed Order DE 9781, and options for cleanup of Western Port Angeles Harbor will be presented. A fact sheet briefly summarizes the information contained in these documents.
Staff will be available to talk one-on-one during the open house sessions. At 7:00 p.m. there will be a presentation, followed by a question and answer period.
- 6:30-7:00 p.m. Open house
- 7:00-8:00 p.m. Presentation and Q&A
- 8:00-8:30 p.m. Open house
The Western Port Angeles Harbor Sediment Cleanup Unit is approximately 1,160 acres located in the harbor from the downtown commercial/industrial area to Ediz Hook.
The remedial investigation shows that sediment contaminants in the western harbor include metals, dioxins/furans, polychlorinated biphenyls (PCBs), and carcinogenic polycyclic aromatic hydrocarbons (cPAHs).
People, pets, or wildlife that physically contact or accidentally eat contaminated sediment may be exposed to hazardous chemicals. People and wildlife may be exposed to contaminants when they eat contaminated fish and shellfish.
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 contaminated sediments, and checking for natural deposition of cleaner material on top of contaminated sediments.
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 smoke stacks and settled out onto marine sediments.
