Background
The Eagle Zinc site is located in the city and township of Hillsboro, Illinois, Montgomery County. The 132-acre site is located in a commercial /industrial/residential area in northeast Hillsboro. The site extends from Smith road to the north of Middle Fork of Shoal Creek on the south. The site operated as a zinc smelter from 1912 to 2003. Other site operations included the production of sulfuric acid and zinc oxide.
Leftover material and contaminants from the manufacturing operations are concentrated in 15 piles, which are mainly located in the central and southern portions of the site. A large pond that formerly provided water for site operations is located in the southwest corner of the site. Buildings formerly used for manufacturing operation currently occupy 20 percent of the site. The site is currently zoned industrial by the city of Hillsboro and legal restrictions on the property limit future site use to industrial use. Local authorities have expressed interest in redeveloping the site.

Site Updates
March 2011
To manage the contamination more effectively, the U.S. EPA split the site into to two areas, called operable units (OUs). The first Operable unit is the contamination associated with the dilapidated buildings on site and Operable unit two is related to the soil, residue piles (waste piles ), ground water, and surface water. In September 2009, EPA signed an interim Record of Decision to address the contamination in OU 1. The selected remedy consists of the following components:
- Building Demolition: The demolition of all buildings on-site, including manufacturing buildings, office buildings and laboratories;
- Off-site disposal of Asbestos Containing Materials and Putrescible Wastes: Proper off-site disposal of asbestos containing materials and putrescible wastes;
- Recycling: Recycling of steel, metal, bricks and other recyclable materials. Any material eligible for recycling will be decontaminated to a level of contamination acceptable to the recycling facility;
- On-site Management Cell with Soil Cover: Consolidation of demolition debris and a one-foot soil cover will be placed on-site to temporarily manage the consolidated debris. The vegetative portion of the soil cover will use native grasses, which will require limited maintenance; and
- Management of Wastes: All non-hazardous waste will be managed onsite under the one-foot soil cover. Any hazardous waste will be placed on-site managed consistent with Resource Conservation and Recovery Act waste pile requirements and incorporated into the final remedial action.
The Remedial Design for operable unit one is expected to be complete in early April. The Remedial Action start will depend largely on whether funding is available for this project this year.
The Remedial Investigation / Feasibility Study is underway and is expected to be complete in June 2011. Community members were interviewed last fall about the site. A community involvement plan will be released in early June 2011 along with a fact sheet distributed to the general public.
