Yard Program updates

Since 2013, we've found almost 1,200 yards that qualify for soil replacement. To date, we have replaced soil in 245 yards within the Yard Program service area. This year we plan on replacing soil in 45 yards in the service area.

The Tacoma Smelter Plume Project is back to work

In January of 2018, the legislature approved the 2017-2019 biennium. For the Yard Program this means we were able to start work on a larger group of properties in 2018. This year we will be working on 39 yards in Tacoma and 16 yards on Vashon-Maury Island.

Current Progress: 2018 Construction Group

In 2018 we will be working on 39 yards in Tacoma (colored blue on map). Twenty-five of the yards are located in Area 2 in the study area. The remaining yards are located outside of the study area. To date, yards that we have worked on outside of the study area have levels of arsenic over the EPA action level and are funded by the EPA. 

Notifying homeowners of sampling data within the study area

Ecology and the Health Department reviewed past sampling results from the EPA's Superfund cleanup site. We notified all homeowners of the sampling results for their property.

If a property qualifies for soil replacement, it may be several years before we are able to meet with you to discuss soil replacement. We have found almost 1,200 properties that qualify for soil replacement within our Yard Program service area.

This is a long-term project. We are working neighborhood by neighborhood to address the most highly contaminated areas of the plume. While you wait for soil replacement, practice healthy actions to reduce your exposure to contaminated soil. For more healthy actions, visit our healthy actions webpage.
