Redevelopment at the Site

The 120-acre Reilly Tar & Chemical Corp. (Indianapolis Plant) Superfund site is located in Indianapolis, Indiana. The site has operated as a specialty chemicals production facility since the early 1950s. Until 1972, a coal-tar refining and wood treatment facility that used creosote also operated at the site. Site operators used a trench, a landfill and several pits on site to dispose of wastes generated on site. A lime pond received boiler cooling water. Waste handling practices resulted in groundwater and soil contamination. EPA placed the site on the Superfund program’s National Priorities List (NPL) in 1984. Cleanup involved extracting and containing groundwater. EPA’s cleanup plan also included constructing a permeable cover over the wood treatment and storage area and removing or treating contaminated soil. Groundwater monitoring is ongoing. Chemical operations continue at the site. Developer Hanwha Q CELLS constructed a 10.8 megawatt solar energy generation facility on the southern 43-acres of the site. The Maywood Solar Farm is the first utility scale solar farm to be constructed on a Superfund site in Region 5. The facility began operation in February 2014.

Activity and Use Limitations

At this site, activity and use limitations that EPA calls institutional controls are in place. Institutional controls play an important role in site remedies because they reduce exposure to contamination by limiting land or resource use. They also guide human behavior. For instance, zoning restrictions prevent land uses – such as residential uses – that are not consistent with the level of cleanup. For more background, see Institutional Controls.
