The St. Maries Creosote site is located along the south bank of the St. Joe River in St. Maries, Idaho. Soil, groundwater and sediment in the river are contaminated with creosote released from a wood treating company that operated on the site from 1939 to 1960.

After years of study and design, construction to clean up contamination will begin in spring 2014. The work will take place over two construction seasons. We plan completion of the upland portion of the work in 2014 but are delaying in-river cleanup actions until 2015. Upland work to be completed this year includes building an underground wall around the contaminated soils, solidifying the deeper contaminated soils in place, and digging up and replacing shallow contaminated soils. We met with local officials and community members at a public meeting in St. Maries on March 19, 2014 to discuss impacts to the community including noise, lights, and odors. We will continue to listen to and respond to community concerns as the cleanup work gets under way. 

We made four changes to the cleanup plan for the St. Maries Creosote Site. The document that describes the changes is called an Explanation of Significant Differences (PDF) (20 pp, 3MB). We issued the original cleanup plan, called a Record of Decision, in July 2007, and accepted and responded to public comments at that time. We are not accepting public comment on these four final changes.
