Terminal 117 Early Action Cleanup


T-117 uplands soil cleanup construction began on schedule in June 2013. During this construction, steel sheet piling is used to isolate contaminated soil and water from the river. PCB contaminated soil is excavated and hauled offsite to a licensed waste landfill.

Several unanticipated underground storage tanks and barrels containing waste oil and other remains have been uncovered on-site; but there have been no impacts or threats to the community from the discovery and handling of these materials.

Air quality and noise are monitored daily during all construction activities, and artificial light is measured during any night work. Air quality levels have consistently been below the limits set by the project, which are below Federal and State guidelines. Up-to-date monitoring data can be found on the project website, “Uplands Construction Updates” tab.

Sediment cleanup will be performed during the open fish window (December 2013 – February 2014) when in-water construction is less likely to harm migrating or spawning fish, or interfere with tribal fishing.
