July 2014

EPA is conducting a five-year review of the St. Regis site. This is the fifth five-year review of the site. The Superfund law requires regular checkups of sites that have been cleaned up with waste managed on-site to make sure the cleanup continues to protect people and the environment. The five-year review is an opportunity for residents and other interested parties to tell EPA about site conditions and any concerns. For an interview or telephone conversation to discuss current site conditions, problems, or related concerns, contact: Leslie Patterson, Remedial Project Manager, 312-886-4904, patterson.leslie@epa.gov, or Heriberto León, Community Involvement Coordinator, 312-886-4360, leon.heriberto@epa.gov.

The Potentially Responsible Parties collected additional soil data in August 2012 and May 2013 under EPA oversight and U.S. Environmental Protection Agency is evaluating this information to further refine and evaluate the cleanup options before selecting a final soil remedy.  The PRPs also collected groundwater and soil data in Operable Units 1 and 3 to evaluate hydraulic capture of the groundwater pump-and-treat system.

The feasibility study, proposed plan, and other site-related documents are available for review at all of the repositories listed on this page.
