Northport Waterfront

We are directing and funding an investigation and cleanup of smelter-related metals contamination on Northport’s waterfront area next to the Town Park, using funds from the Eastern Washington Clean Sites Initiative. 

The project area is permanently and seasonally exposed areas of the Columbia River bank and shore next to the park and around the boat launch. From the river, this area is between Smelter Rock downstream to the Northport Highway 25 bridge, and is associated with the historic Le Roi Smelter. The area remains polluted by smelter wastes that were dumped and spread along the shore.

Our goals are protecting people and restoring the shoreline environment next to the park. We will continue to work with local government, businesses, and residents during the cleanup process to understand your concerns and the community’s vision for the waterfront. We welcome your input during and outside of comment periods. 

Proposed cleanup plan

We held a comment period on the draft Cleanup Action Plan May 2 through June 1, 2022. We proposed to remove and cap contamination, and encourage recreation in cleaned up areas. We will plan work near the water when levels are lowest and in stages that will not risk impacts to the site or Columbia River due to rising water. Excavated soil, sediment (beach sand and gravel), and slag (smelter waste) will be taken to a permitted landfill for disposal. The estimated cost of cleanup is $4.9- to $5.4-million.

You can learn more in the public notice that was mailed to the community and our slides from the online public meeting we held May 17. We responded to comments from six people. 

The next step is the engineering design for the cleanup. The draft engineering design report will be available for public review and comment before final cleanup begins.

Contamination and cleanup options reports published

We held a comment period on the draft Remedial Investigation and Feasibility Study (RI/FS) May 3 through June 2, 2021. The RI explains the extent and locations of contaminants, and the FS evaluates cleanup options. You can learn more in the public notice that was mailed to the community and our slides from the online public meeting we held May 19. We responded to four sets of comments on the RI/FS.

Beach sampling complete

We held a comment period March 13 - April 11, 2019, for the Remedial Investigation (RI) Work Plan and related State Environmental Policy Act (SEPA) documents. Learn more about the investigation in the notice that was mailed to the community. We responded to comments from two people and thank them for their input.

The information in the draft Remedial Investigation Report showed the following metals were found most frequently throughout the site at levels posing a risk to human health and the environment:

• Copper
• Lead
• Zinc

Metal levels do not pose an immediate, acute human health risk. However, long-term exposure may increase the risk of certain health problems. You can take simple actions to protect yourself and your family from exposure.
