We invite you to submit written comments on updated cleanup documents for the East Bay Redevelopment site.  New development is planned for one portion of the site, at 510 State Ave NE.

Cleanup work was finished in 2017 for the site, which allowed for development that did not disturb the cap. The property owners—the City of Olympia, the Port of Olympia, and LOTT—are formally changing the cleanup plans to allow for construction and development that will disturb the cap during construction. The new cleanup plan requires measures to protect people and the environment during and after construction of the new development.

Several updated documents are available for review and comment:

  • An updated agreed order — a legal agreement that requires the property owners to follow specific cleanup plans.
  • Updated cleanup action plan — outlines the recommended cleanup.
  • SEPA Checklist  This describes the potential impacts of the project on the surrounding environment. Ecology reviewed the checklist and determined that the action was not likely to have significant negative impacts (a Determination of Non-Significance).

From the late 1880s until 1968, the site was used for timber-related industries. Since then, the site has been used for commercial and light industrial activities and storage. Previous users included a sawmill, planing mill, shingle mill, and plywood manufacturers.

Historic activities caused soil and groundwater contamination. Total petroleum hydrocarbons (TPHs), carcinogenic polycyclic aromatic hydrocarbons, dioxins and furans, and metals were detected above state cleanup levels in soil. Investigations also revealed TPHs and metals in groundwater above state cleanup levels or screening levels.

The Port of Olympia (port) entered the Voluntary Cleanup Program in January 2007.  The site was transferred to a formal cleanup process in February 2008. 

In June 2010, LOTT Cleanup Water Alliance (LOTT) and the City of Olympia (city) purchased two parcels that are part of the East Bay site.  The city, LOTT, and the port are now all responsible for the cleanup of the East Bay Redevelopment site.  All three parties entered into a legal agreement (Agreed Order) to continue with site work. 

From 2009-2012, two partial cleanups (interim actions) were done in to remove and contain contaminated soil on the southern half of the site. We conducted this cleanup during infrastructure construction of the Hands On Children's Museum, the LOTT and East Bay public plazas, and associated roads.

In 2017, Ecology worked with the City of Olympia, the Port of Olympia, and LOTT to complete cleanup of the East Bay Redevelopment site. To clean up the site, some soil contamination hot spots were removed. Contaminated soil that remained was covered with a cap of clean soil, pavement, or buildings. Tests showed that the groundwater is no longer contaminated.


Ecology wants to keep you involved!  You will have the chance to review and comment on key documents during the investigation process.  Documents will be at this web site and at the repository locations listed to the right as they become available.
