Northport Waterfront

Excavation and capping work complete

Crews excavated remaining contamination from the seasonal beach and the boat dock area, and filled in the bay, jetty, and excavated areas with clean materials. Although not as much as last season, some of the excavated material classified as hazardous waste.

The access road east of Park Road continues to be open for all traffic accessing the Town Park, boat launch, and waterfront.

We are now working on recreational improvements and restoring excavated areas, including:

• Planting two red maple trees on the jetty to replace the former elms and provide shade during the summer heat.
• Installing two benches and a pavilion picnic area.
• Replanting all areas impacted by earthwork with native vegetation, including topsoil, compost, and mulch. Steep slopes will be stabilized.

2024 cleanup summary

Last year, about half the work was completed. Due to the river conditions, we weren't able to work in all five management areas. However, the contractor made significant progress on the seasonal beach, and all hillside cleanup and capping work is complete.

The lead levels in about 2,000 tons of material removed from the hillside and some of the seasonal beach were hazardous waste under federal standards. This waste required stabilization processing for the lead, which was done at a chemical waste facility in Oregon. Another 13,000 tons of waste were sent to the Stevens County Landfill, and about 4,000 tons of excavated river rock above 6 inches in diameter was retained and mixed with imported materials for reuse on site. 

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. 

Engineering design for cleanup complete, project beginning February 2024

Ecology held a public comment period for the draft 100% Engineering Design Report August 22 through October 5, 2023. The report provides further details about how the Cleanup Action Plan will be completed, such as project sequencing, site staging and hauling, stormwater management, yardage estimates, and public access improvement plans following cleanup. You can learn more in the public notice we mailed to the community. We responded to comments from one person and three organizations.

Six companies submitted bids for the cleanup. The winning bidder is Versatile Industries, Inc. of Ione. 

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 $10.5-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. 

We reviewed the actions described in our Cleanup Action Plan using the State Environmental Policy Act (SEPA) checklist, and decided they won’t negatively affect people or the environment. We held a public comment period August 8 through 22, 2022, and didn't receive any comments.

We decided the project will not have negative impacts because the activities are minimal and temporary. Measures to address potential impacts include:

• Controlling erosion by installing silt fencing along the shoreline, covering stockpiles (if any) with plastic sheeting, maintenance to address rutting or rill development, infill planting, and limiting vehicle traffic.
• Controlling dust by wetting down exposed areas, covering truck loads, and monitoring transportation routes.
• Limiting vehicle idling times to reduce emissions.
• Working along the shoreline when the Columbia River levels are low to avoid working in or over water.
• Protecting workers with site-specific safety protocols and appropriate personal protective equipment.

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 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.
