The road between Eagle Harbor Drive and the Wyckoff/Eagle Harbor Superfund site, will be  closed on Wednesday, February 3, from 7:00 a.m. to 7:00 p.m. Work crews will dig a drainage ditch and an infiltration trench to address water drainage issues on the road. The cold temperatures have caused water on the road to freeze, resulting in icy conditions. EPA intends to address this public safety issue as soon as possible. The U.S. Army Corps of Engineers will perform the work.

Many thanks to the community for your patience while this important work takes place.

What’s Happening?

On July 27, EPA plans to oversee an upland field investigation at the site. The investigation will take place mostly within the fenced-in former process area. Limited work may take place along the west beach, next to the sheet pile wall. EPA is coordinating the investigation to find out how much and what types of buried debris exist at the site, and to collect soil samples. The results of the field investigation will inform the perimeter wall replacement design. We expect the field investigation will wrap up in early September. During the field investigation, there may be a temporary release of creosote-related odors while crews dig test pits. The EPA contractor – Jacobs Engineers - has prepared a plan to address noxious odors, including using odor-suppressing foam. The test pits will be quickly backfilled, and any related vapors should quickly disperse. Here is a link to EPA site page.

On May 10, 2019, USEPA issued a cleanup plan (Record of Decision Amendment Part II) to address the upland and nearshore sediment contamination at the former wood treating facility at the Wyckoff/ Eagle Harbor superfund Site. The cleanup plan modifies the earlier “containment” cleanup decision, issued in 2000. The new remedy will provide better protection of Eagle Harbor bay and the lower aquifer beneath the site by preventing the creosote contamination from migrating off site. The selected remedy will be built in phases over a period 8 to 10 years and is scheduled to be completed by 2032.

Update on new Access Road - Creosote Place N.E.

The realignment of Creosote Place N.E. is ahead of schedule and was opened to the public on July 3. The realignment was designed by the U.S. Army Corps of Engineers under EPA’s
oversight, and constructed by their contractor. Tree planting and gate installation will occur later this fall. The trees will help with revegetation of the old road. The gate will be used to control access to the site during future construction, for health and safety considerations.

The Wyckoff Superfund Site is located on the eastern side of Bainbridge Island forming the entry to Eagle Harbor, in central Puget Sound. It's located on the former Wyckoff Company wood-treatment facility and subtidal and intertidal sediments in Eagle Harbor. 

A creosote wood-treatment facility operated on the Point for 85 years. These operations resulted in the soil and groundwater beneath the Former Process Area (the Point) being contaminated with chemicals from the wood-treatment process, primarily creosote-derived polycyclic aromatic hydrocarbons (PAHs), pentachlorophenol (PCP), aromatic carrier oils, and dioxins/furans. These contaminants pose a risk to public health and the environment.

It is in an area of significant wave action, exposed to a wide northeasterly fetch and vulnerable to constant ferry wake. It is located adjacent to an ancestral and important current tribal fishing ground, with established eelgrass beds. The City of Bainbridge Island and the Bainbridge Island Metro Park and Recreation District have purchased the Wyckoff property, including the Point, with plans to establish a showcase regional public park. The City owns the Point, while approximately half of the site, including the
Japanese-American World War II Exclusion Memorial, are co-owned by the City of
Bainbridge and Bainbridge Island Metropolitan Park & Recreation District. Development of the park must occur in accordance with requirements stated in the 2006 Agreed Order entered into between the Department of Ecology and the City of Bainbridge Island.

EPA listed Wyckoff/Eagle Harbor as a Superfund Site in 1987 and began Superfund
cleanup actions in 1991. The Wyckoff/Eagle Harbor Superfund Site encompasses contaminated areas within Eagle Harbor. The Superfund Site was divided into four operable units (OU). Three of these areas (OU’s) are within the subject site of the 2006 Agreed Order, including the East Harbor OU, Wyckoff Soil OU and Wyckoff Groundwater OU. More information about these areas can be found in Ecology’s 2006 Phase III Acquisition Area Fact Sheet or on the EPA webpage.

EPA, as the lead agency for the site, completed plans for cleanup at the site. This work is being done in close coordination with Ecology. EPA conducted an extensive Focused Feasibility Study (FFS) to better understand the extent and possible options for cleanup of creosote on the site (the Point).  

The FFS evaluated possible future cleanup options to clean up the creosote contamination. Based on the FFS, EPA proposed a comprehensive cleanup plan in April 2016 (Proposed Plan) that included two phases of work: phase one work for the nearshore and beach areas and a later, phase two stage, for work in the upland areas to immobilize the soil contamination and treat contaminated groundwater.

The site-wide cleanup work was divided into two phases in order to expedite the priority cleanup of the beaches and the containment perimeter wall replacement to keep the creosote from reaching Puget Sound. Phase two of the cleanup will permanently contain and immobilize the creosote liquid and other contaminants in the upland soils and groundwater, protecting drinking water aquifers and preventing contaminants from reaching Puget Sound.

Phase one is documented in a Record of Decision Amendment 1 dated May 14, 2018.
The first phase of cleanup (for in-water and containment wall replacement) is expected to cost an estimated $36.3 million and take three to four years to complete. EPA’s Record of Decision Amendment 2 for the phase two cleanup was also documented in May 2019. Ecology is legally liable to reimburse EPA for ten percent of the remedial actions costs, pursuant to paragraph 16 of Superfund State Contract dated on March 1995.

Ecology has been responsible for the Operations and Maintenance of the Groundwater Extraction and Treatment System at the site since April 2012.



EPA and Washington State Department of Ecology are working to help you stay informed about the Wyckoff/Eagle Harbor Superfund Site Cleanup.

The Wyckoff/Eagle Harbor Superfund Site cleanup is important for Bainbridge Island and our region. The U.S. Environmental Protection Agency (EPA) and the Washington State Department of Ecology (Ecology) would like to share information on progress made at the site, and about future work. Please see EPA’s webpage for the latest information about site and plans for completing the cleanup.

Preventing historic creosote compounds in the Point from moving into the environment is a high priority. EPA has been pursuing a permanent remedy for the site to enhance the current contingent containment remedy. The existing remedy includes using a perimeter wall, site cap and active groundwater extraction system. The Department of Ecology agrees that containment is needed in the short-term, but has two concerns about long-term protectiveness and stewardship:

  • Leaving large amounts of mobile contamination at this site is not a good idea, especially given the sensitive location on the shores of Puget Sound.
  • The state (or Ecology) does not want to accept the long-term financial burden that this action places on the state to operate, maintain, and periodically rebuild the containment remedy.

To address the question of whether other practical options existed for a less costly and more permanent remedy, Ecology conducted an evaluation with the assistance of a panel of regional and national experts and a Steering Committee of local community and tribal members. This Generational Remedy Evaluation process looked at additional protective solutions that would reduce the remaining volume and mobility of the contamination.  

The Wyckoff Generational Remedy Evaluation Report August 2010 contains the details of the study and its outcomes.
