Spokane River Metals Barker Road South

Facility Site ID: 615198 Cleanup Site ID: 11588

Public Comment Period September 22, 2022-October 21, 2022

Ecology invites you to review and comment on the draft Periodic Review Report for the Spokane River Shoreline Metals sites. We complete a periodic review about every five years at sites where some contamination remains after cleanup. The purpose of the review is to make sure the cleanup still protects human health and the environment.

The cleanups continue to protect human health and the environment from the capped contaminated sediments. However, contaminant concentrations have increased in some cases and new contaminated sediments have been deposited on the caps. This likely means upstream sources are continuing to impact the river and could pose a risk to human health and the environment if they are not controlled.

We will continue monitoring to ensure that the sites continue to be safe for human health and the environment. A monitoring study evaluating sediments entering the site at the Washington-Idaho border would help assess the potential for recontamination.

Next steps

Ecology will review all comments received during the comment period and update the periodic review if needed. If no significant changes are made, the periodic review will become final. If significant changes are made, an additional public comment period will be held. We will hold an online public meeting if 10 or more people request one.

Site Background

Looking from the river south up the ravine
Looking from the river south up the ravine
Contaminants from historic mining practices in Idaho’s Coeur d’Alene Basin washed downstream and settled in soil and sediment along some Spokane River beaches. 

The U.S. Environmental Protection Agency (EPA) conducted studies of the mining contaminants in the Coeur d’Alene Basin and began a wide-spread cleanup of the Bunker Hill Mining and Metallurgical Superfund Site. As part of the EPA study and studies Ecology conducted, nine beaches in Washington were cleaned up, including Barker Road South.

The Barker Road Bridge South site is located north of I-90 via exit 293 and lies immediately south and east of the Barker Road Bridge in Spokane Valley. 

Contamination

The mining-related contaminants include arseniccadmiumlead, and zinc.

Ecology planned to build a fence around the Barker Road South site near the Centennial Trail. The fence would have prevented access to contaminated soil at the bottom of the ravine along the Spokane River bank in this area. 

During a public comment period held August 10 through September 9, 2009, local residents and river users expressed concerns about the fencing in the site. Concerns included river access, safety and questions about the proposed fence at the site. The original schedule for Barker Road South was anticipated to begin after the Barker Road North bridge construction was completed. The bridge was undergoing construction, and delays in the bridge project would complicate river access if Ecology’s project continued at the same time.

Ecology re-evaluated the proposed Barker Road South cleanup in 2013 and decided to install a sign warning users about the contamination.

Ecology will conduct a periodic review about every five years following site cleanup. The purposes of the review are to evaluate site conditions when contaminants are capped and ensure the cleanup continues to protect human health and the environment.
