DuPont/Chemours plant site near Chicago gets final clean-up plan from EPA


The U.S. Environmental Protection Agency (EPA) announced a $26.6 million final plan to clean up soil tainted with arsenic, lead, zinc, and cadmium at the former DuPont/Chemours plant at in East Chicago, IN.

DuPont spun off Chemours as a publicly traded company, with both companies having responsibilities for sites with environmental challenges.

The plant is located south of Zone 3 of the USS Lead Superfund site, a residential area where a separate federal cleanup is currently in progress.

The cleanup at the former DuPont/Chemours plant helps pave the way for redevelopment opportunities in East Chicago that will bring jobs and economic growth to the community,” said EPA Regional Administrator Cathy Stepp.

Following a more than 90-day public comment period on the agency’s proposed cleanup plan and a thorough review of 200 comments, EPA revised its plan to require that all excavated contaminated soil be disposed of off-site. Groundwater treatment, closing the solid waste landfill, long-term monitoring, and maintenance are also required.

The Indiana Department of Natural Resources maintains a 172-acre natural area on-site which was cleaned up under a separate corrective action in 2014.
