Oakland Bay and Shelton Harbor Sediments

Facility Site ID: 18051 Cleanup Site ID: 13007

Public Comment Period February 15, 2018-March 19, 2018

YOUR COMMENTS INVITED!

We are working with Simpson Timber Company to clean up contamination from historic industrial activities in Shelton Harbor. A plan to clean up part of the site, called an Interim Action Plan, is available for public comment. The Interim Action Plan:

·       Describes the nature and extent of contamination at the Shelton Harbor sediment cleanup unit - the area addressed by the interim action.

·       Evaluates different cleanup options for portions of the site.

·       Proposes cleanup actions to protect people and the environment from contamination in the interim action areas.


We also reviewed information about the cleanup activities to see if they will have negative impacts on people or the environment. State Environmental Policy Act (SEPA) documents explain this review and are also available for public comment.

For more detailed information, click the link below to review a fact sheet or the Interim Action Work Plan. You can submit written comments to Joyce Mercuri by
email or mail from February 15th through March 19th.

Status Update

Ecology held a public comment period from February 15 to March 19, 2018 for the Shelton Harbor Interim Action Plan (IA) and State Environmental Policy Act (SEPA) Mitigated Determination of Nonsignificance determination.

Ecology received two comment letters, which did not lead to substantive changes. 

The comments and their responses are available now in the Responsiveness Summary.   To view an electronic copy of the responsiveness summary, click the following link:

Shelton Harbor Cleanup

In the summer of 2017, we made a formal legal agreement, called an agreed order, with the Simpson Timber Company (Simpson) to begin cleanup in Shelton Harbor. You can click the link below to read the document. The new agreed order requires Simpson to:
  • Describe the types and extent of contamination in Shelton Harbor through a remedial investigation.
  • Develop and carry out a partial cleanup plan called an interim action.
  • Evaluate cleanup options through a feasibility study.
  • Choose cleanup methods through a draft cleanup plan.

You can find the agreed order and a copy of the comments we received and our responses to them in the links below.

Why Cleanup?

Extensive research into sediment contamination in Oakland Bay showed that contamination was most concentrated in Shelton Harbor. To address that contamination, we have defined a portion of the bay, the Shelton Harbor Sediment Cleanup Unit.

The Oakland Bay Sediment Investigation, detailed below, showed contamination from dioxin, excessive wood waste, and cPAHs (carcinogenic polycyclic aromatic hydrocarbons) in the harbor. The highest concentrations of these contaminants are in Shelton Harbor, at the western end of Oakland Bay.

Through this cleanup work, Ecology has an opportunity to contribute to the success of a planned habitat restoration project in Shelton Harbor. We plan to dovetail restoration with the first stages of cleanup work in order to:

·       Make both projects more efficient.

·       Ensure that the restoration project is built on a foundation that meets state cleanup standards.

Sediment Study

In 2008 and 2009, with support from the Puget Sound Initiative, Ecology’s Toxics Cleanup Program investigated the health of the sediments in Oakland Bay. Sediment contamination can impact plants and animals that live in or around the contaminated sediment. Some contaminants can have broader impacts when they move through the food chain.

Ecology chose Oakland Bay because Shelton Harbor has a history of heavy industrial use and previous studies showed evidence of contamination. In addition, Oakland Bay is one of the most productive shellfish growing areas in the country.

Industrial uses of Oakland Bay resulted in sediment contamination in Shelton Harbor and surrounding areas. Chemicals, wood waste, and waste water from timber and wood product manufacturing industries have been discharged into Oakland Bay.

 

A report on the Oakland Bay Sediment Characterization Study was released for public review and comment in December 2010. The full text of the report is available by clicking the links below. The Sediment Investigation Report contains information about:

·        Location and amount of chemicals and wood waste in the sediment.

·        Amount of sediment movement and deposition in Shelton Harbor and Oakland Bay.

·        Potential effects of sediment contamination on the health of creatures living on or in the sediment.

·        Possible sources of dioxin found in sediment.

 

IS IT SAFE TO EAT SHELLFISH FROM OAKLAND BAY?

According to a health consultation from the Department of Health, even people who eat large amounts of shellfish from Oakland bay are very unlikely to see harmful health effects from the shellfish. The health assessment also determined that touching, breathing in, or accidentally eating contaminated sediment from Oakland bay is very unlikely to harm people’s health.

South Puget Sound Regional Background

If we removed every contaminant in South Puget Sound, would the sediment, air, and water entering the harbor re-contaminate the area? An update to the rule that guides our cleanup work in sediment (Chapter 173-204) introduced the concept of background chemical concentration levels to address questions like this.

Regional background includes chemical concentrations in sediment from diffuse sources, like regional stormwater or atmospheric deposition that are not linked to a specific source or release.

In 2018, we completed a study of the regional background levels of two contaminants found in Oakland Bay and Shelton Harbor. The South Puget Sound Regional Background study uses existing data from areas surrounding Squaxin Island; south of Harstine Island; and five inlets, including Henderson Inlet, Budd Inlet, Eld Inlet, Totten Inlet and Oakland Bay.

The results of this study, in combination with our understanding of the risk that contaminants pose to human health and the environment, help us decide cleanup levels and inform cleanup decisions in the area.

Other Work In Oakland Bay

Ecology's Water Quality Program is currently developing a plan to address water quality problems in Oakland Bay, including fecal coliform bacteria.  For more information about this work visit http://www.ecy.wa.gov/programs/wq/tmdl/oakland_bay/index.html.

Site use restrictions called institutional controls are in effect

Institutional controls can be fences, signs, or restrictions on how the property is used. For instance, an institutional control may prohibit installing drinking water wells or disturbing a protective cap that isolates contamination. These restrictions keep the contamination contained and keep people from being exposed to the contamination. The controls are usually listed in environmental covenants recorded with the county.

Periodic reviews are required when institutional controls are required at a site. Ecology conducts reviews to make sure the controls remain effective and the cleanup still protects human health and the environment. We conduct periodic reviews about every five years.
