The 120-acre Reilly Tar & Chemical Corporation site has been used for the production of specialty chemicals and related products 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 from operations. A lime pond received boiler cooling water. Waste handling practices resulted in ground water and soil contamination.
EPA placed the site on the National Priorities List (NPL) in 1984. A ground water extraction system, constructed in 1994, has contained ground water contamination to the site area. The system extracts contaminated ground water and sends it to the local wastewater treatment plant. The site’s potentially responsible party (PRP) has completed cleanup activities under EPA and Indiana Department of Environmental Management (IDEM) oversight.
In 1997, the PRP addressed four on-site areas of soil contamination by removing and treating the soil. The PRP also addressed contamination in a fifth area by solidifying the contaminated material and placing a soil cover over the solidified material. In 1999, the PRP completed cleanup on the wood treatment and storage area of the site. Cleanup included placement of a permeable cover over the area. A soil vapor treatment system operated at the site until 2005. Fencing surrounds the site.

The 120- acre Reilly Tar & Chemical Corporation site began producing specialty chemicals and related products in the early 1950s. Reilly continues to operate a specialty chemical plant on the northern portion of the property. Until 1972, a coal-tar refining and wood treatment facility, which used creosote, operated on the site. A trench, a landfill, and several pits used to dispose of wastes are located onsite. A lime pond received boiler cooling water.
EPA placed the site on the National Priorities List (NPL) in 1984. A ground water extraction system, constructed in 1994, has contained ground water contamination to the site area. The system extracts contaminated ground water and sends it to the local wastewater treatment plant. In 1999, the site’s potentially responsible party completed all active cleanup activities under EPA and Indiana Department of Environmental Management (IDEM) oversight.
There are approximately 5,200 residents living within three miles of the site. Aboveground tanks and process equipment cover much of the northern 1/3 of the site, where the Reilly chemical plant is located. The entire property is fenced.
Construction of a 10.82MW (DC) solar renewable energy park supported by Indianapolis Power & Light’s (IPL) Rate Renewable Energy Production (REP) Program was completed on the southern portion of the Reilly Tar Site in February 2014.
The facility was designed and built over a cover that had been previously installed as part of the site’s remedy. EPA and IDEM provided oversight to ensure the continued protectiveness of the cover. The system went online in February 2014 and is expected to reduce CO2 emissions by 13,235 metric tons per year.
