Spokane River Metals Barker Road North

Facility Site ID: 615198 Cleanup Site ID: 11587

Public Comment Period September 22, 2022-October 22, 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

Barker Road North site after cleanup

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 North.

The site is on the north bank of the Spokane River, east of and next to the Barker Road Bridge.

Contamination

The mining-related contaminants include arseniccadmiumlead, and zinc.

Cleanup

The cleanup was completed in 2012. Contaminated sediment was excavated and properly disposed. Remaining metals-contaminated soil was covered with a protective cap to limit exposure to humans and wildlife. The area was replanted with native riparian vegetation.

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.
