St. Maries Creosote

On this page:

The St. Maries Creosote Site is located on the edge of the City of St. Maries, Idaho, along the south bank of the St. Joe River. Studies done by the potentially responsible parties and EPA found that sediments, soils and groundwater have been contaminated with creosote from the former wood-pole treating plant.

EPA released its revised Proposed Plan for cleaning up the site in December 2006. The public comment period was held from December 6, 2006 to January 5, 2007, and a public hearing held on December 13, 2006. On July 20, 2007, EPA signed the final cleanup plan for the site, known as the Record of Decision (ROD) (PDF) (187 pp, 4MB to start). The Consent Decree (PDF) (64 pp, 2.3MB), a legal document governing the cleanup, became effective on February 9, 2010.

IDHW’s Health Assessment for the St. Maries site Exit EPA Disclaimer is now available.
