Background

The DuPont facility is at 5215 Kennedy Ave. The Natural Area and Buffer Zone make up the 195-acre eastern portion of the facility. An industrial area along Gary and Cline Avenues roughly forms the eastern and northern boundary, the Grand Calumet River is the southern boundary and the former DuPont manufacturing area is the western boundary. The area near the Natural Area and Buffer Zone is mostly industrial with a residential area – East Chicago’s Riley Park community – to the northwest.

The Natural Area is an undeveloped tract of original lakeplain/dunes land with alternating dry sand ridges and wet organic swales.

The entire DuPont facility consists of the Natural Area and adjacent Buffer Zone, plus 29 acres leased for active industrial use, 30 acres of solid waste landfill, 155 acres of former industrial property that could be redeveloped and 52 acres of open and/or filled land.

Site Updates

August 2014

EPA took public comments on the proposed Natural Area cleanup plan between Aug. 13 and Sept. 12, 2014. If there is enough interest, EPA will also hold a public meeting to present the proposed plan, answer questions and accept oral comments. For more information, contact Project Manager Jennifer Dodds.

Under a proposed cleanup plan, EPA would clean up metal-contaminated soil while ensuring the protection and continued long-term stewardship and conservation of the 172-acre Natural Area in the eastern portion of the DuPont Facility site.  DuPont gave the Natural Area to the Indiana Department of Natural Resources as a conservation easement. The Nature Conservancy has managed the area since 1999. It is home to many rare, threatened or endangered plant and wildlife species.

DuPont found that releases from its former industrial property had contaminated western portions of the Natural Area. To immediately protect the Natural Area and improve the quality of its unique habitat, the company did an interim cleanup in the fall of 2012. DuPont dug up and removed about 77,000 cubic yards of soil with high concentrations of metals – mostly lead, arsenic and zinc – from 20 acres of the adjacent Buffer Zone and a small portion of the Natural Area, and stockpiled it on their contaminated industrial property.

The 23-acre Buffer Zone, just west of the Natural Area, has been affected by releases from the former industrial portion of the site. DuPont’s investigations found that surface soil concentrations of metals such as antimony, cadmium, chromium, copper, lead and zinc were above levels established to protect human health and the environment.

EPA’s proposed plan would clean up remaining contamination and deal with the stockpiled soil from the interim cleanup. It would be done under the legal authority of the federal Resource Conservation and Recovery Act.  RCRA requires public participation in the cleanup process, so EPA has set a public comment period.
