Northport City Park
Independent Cleanup Completed 2014
Approximately 7,714 tons of contaminated soil was transported to a containment area on the LeRoi Smelter site that was created by the U.S. Environmental Protection Agency (EPA). Some contaminated soil remains where further excavation would have damaged existing trees, buildings, or rail lines. These areas have been capped to prevent human contact and prevent water from infiltrating or moving the contaminated soil.
An environmental covenant was recorded on the property to document the remaining contamination. BNSF must inspect the cap annually and submit reports to Ecology.
Periodic Reviews
The first periodic review report was completed in December 2019. Ecology visited the site on August 21, 2019, and found that the engineered controls remain intact.
Site History
Smelter operations impacted properties outside the smelter site, including the City Park, BNSF right-of-way, and Northport Waterfront. Soils at and near the smelter were contaminated with lead, arsenic, and other metals.
In 2003, the EPA conducted a Removal Site Evaluation of the smelter site and residential and community properties in Northport. Remedial activities began in July 2004 and included excavating and consolidating mine-waste-contaminated materials at the smelter, constructing a containment area, and capping the area.
A subsurface evaluation was conducted at the Park in 2004. Lead and arsenic concentrations were higher than state standards, primarily in shallow subsurface soils, which led BNSF to complete further independent cleanup.
Voluntary Cleanup Program
This site was cleaned up under our Voluntary Cleanup Program, which provides technical help to owners of contaminated sites.
Voluntary Cleanup Program customers pay fees to cover our costs for technical help and reviewing cleanup reports. Sites in this program must meet the same cleanup standards as the sites Ecology manages under legal orders.
Site use restrictions called institutional controls are in effect
Institutional controls can be fences, signs, or restrictions on how the property is used. For instance, an institutional control may prohibit installing drinking water wells or disturbing a protective cap that isolates contamination. These restrictions keep the contamination contained and keep people from being exposed to the contamination. The controls are usually listed in environmental covenants recorded with the county.
Periodic reviews are required when institutional controls are required at a site. Ecology conducts reviews to make sure the controls remain effective and the cleanup still protects human health and the environment. We conduct periodic reviews about every five years.
