July 2013

The design of the selected remedy for Operable Unit 2, which addresses remaining soil or groundwater contamination associated with the site, is underway. EPA anticipates that construction of the project will begin in fiscal year 2014. The community will be informed as updates become available.

October 2012

On September 6, 2012, U.S. EPA signed the Record of Decision (ROD) for Operable Unit 2 of the Eagle Zinc Superfund Site. The selected remedy consists of the following components:

The ROD is available to view on-line or in the information repository at the Hillsboro Public Library. The next step in the Superfund process is to design the the selected remedy. The design is currently underway and should be final by next summer.

June 2012

The U.S. EPA has completed a supplemental remedial investigation (SRI) and a Feasibility Study (FS) to address contamination in operable unit (OU) 2 of the site.  The SRI determined that there are unacceptable risks to future industrial and construction workers from the high concentration of heavy metals—zinc, lead, cadmium, etc.—in the soil and residue.  In addition, there is an unacceptable risk to the sediment dwelling organisms due to high concentrations of zinc and cadmium in the sediment and surface water.  The FS evaluated options to address these unacceptable risks.

The two documents can be found online and at the Hillsboro Public Library. The Proposed Plan summarizes the SRI and FS documents and presents EPA's preferred option for addressing the site's contamination. The option has the following components:

EPA encourages the community to participate in the Superfund process by commenting on the proposed plan. You can make comments at the public meeting on June 14, or submit comments in writing online or via post mail.  EPA will respond to public comments in a document called the Responsiveness Summary—a section of the final decision document.

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:

The Remedial Design for operable unit one is complete. The Remedial Action start will depend largely on whether funding is available for this project this year.

The Remedial Investigation / Feasibility Study for OU 2 is nearly complete and a final decision for the Site is expected by September 2012. Community members were interviewed fall 2010 about the site. A community involvement plan is available to the general public online and at the Hillsboro Public Library.
