Site Description

The 312-acre Eagle Zinc Superfund site is located in a mixed commercial/industrial and residential area on the northeast side of Hillsboro in Montgomery County, Illinois. Active industrial operations ceased at Eagle Zinc in 2003. Currently, there are 23 structures on the site. Recent sampling results indicated the presence of high levels of lead contamination in area soil and in the structures that could pose a human health risk.

The Eagle Zinc site extends from Smith Road south to an unnamed tributary to the Middle Fork of Shoal Creek. Industrial Drive extends north and south along much of the site's eastern boundary. To the north are Smith Street, a small industrial facility called Hayes Abrasives, a golf course, and farm fields. The site is zoned commercial/industrial and Hillsboro has indicated interest in acquiring the property for use as an industrial park.

EPA placed the Eagle Zinc site on the National Priorities List in 2007.

Site Responsibility

The Eagle Zinc site is being addressed by federal and State actions.

Threats and Contaminants

Soil and buildings at the Eagle Zinc site are contaminated with inorganic contaminants such as lead. Residue piles at the site may pose a leaching hazard to groundwater and ultimately to surface water drainage areas.

Humans could be exposed to site contaminants by dermal contact with soil and debris or by ingesting contaminated soil or groundwater. Over the long term, exposure to thse contaminants could cause non-carinogenic health effects.

Cleanup Progress

EPA has organized the Eagle Zinc site into two portions - or operable units (OUs):

• Operable Unit 1: Contaminated Buildings
• Operable Unit 2: Multi-media (Soil, Groundwater, Surface Water, and Residue Piles)

In May 2008, Illinois EPA conducted a sampling event in and around the 23 structures on the Eagle Zinc site. Results indicated high levels of lead contamination that could pose a health risk to anyone who came into contact with it. Also, the buildings were in dilapidated condition and at risk of collapse. 

In September 2009, EPA signed an Interim Record of Decision (ROD) that contained the selected cleanup remedy for OU1. The remedy consists of demolition of the contaminated buildings, recycling as much of the building materials as possible, and then managing the residual building debris on site under a soil cover.

In May 2012, EPA completed a remedial investigation (RI) and feasibility study (FS) at the site. The RI report discussed the levels of contaminants found in site sediment, soil, surface water, and waste materials and presents the estimated potential human health and ecological risks posed by the contaminants. The FS report presents the various cleanup options that EPA evaluated to address the potential health risks. In September 2012, EPA signed the final ROD for the Eagle Zinc site, which contains the selected cleanup remedy for OU2, which consists of: 1) excavation of contaminated soil and sediment with disposal in an on-site containment cell, 2) and modification of the site surface water drainage system and wetlands around the newly constructed on-site containment cell.

EPA completed the final remedial design for the OU1 interim remedial action in spring 2014 to include: 1) demolition of all on-site buildings, 2) off site disposal of asbestos-containing material (ACM) and putrescible wastes, 3) recycling, to the extent feasible, of steel, zinc oxide, and brick, and 4) creation of a temporary on-site cell for the disposal of the remaining nonhazardous material. 

EPA began construction work in December 2014 to implement the remedial design for OU1 and anticipates that the work will be completed by summer 2015,

EPA also anticipates completing the remedial design for the final remedy (OU2) in summer 2015. Pending funding availability, start of construction could be as soon as fall 2015. Completion of the OU2 work would take about a year.

 

Community Involvement

EPA and partner agency Illinois EPA interact with the Hillsboro community in accordance with the site-specific Community Involvement Plan (CIP), which is available for view at the Hillsboro Public Library. Other site documents, such as the 2009 and 2012 RODs, are also available to the public for viewing at the library.

Congressional Interest

Federal, state, and local officials are regularly in contact with EPA and/or partner agency Illinois EPA concerning the progress of EPA cleanup work at the Eagle Zinc site.

Property Reuse

Hillsboro has indicated interest in acquiring the Eagle Zinc site property after all cleanups are completed so that it can be developed into an industrial park.
