ALCOA PROPERTIES

EPA ID# ILSFN0508010
Last Updated: November, 2013

Site Description

In 1902, aluminum production operations began at the North Alcoa site.  The site was formerly the location of Pittsburgh Lake which was filled in by waste and fill associated with the Alcoa production operations.  The largest volume of material at the site is bauxite residue, which is surrounded by gypsum dikes utilized to contain the bauxite at the site.  The bauxite is contained in three large areas, called residue disposal areas (RDA's) located on the northeastern portion of the property.  The plant operated until the late 1950's and by the mid 1960's, most of the production facilities had been demolished and the land sold.  The site is located in an industrial area with active commercial operations occurring on the southern portion of the property.  A recreational area is currently located to the northwest of the site. 

Site Responsibility

This site is a Superfund alternative site with the potentially responsible parties conducting the current work under an RI/FS agreement with Federal and state oversight.

Threats and Contaminants

Site soils are contaminated with inorganic and radionuclide compounds

Cleanup Progress

In December 2001, EPA entered into an administrative order on consent with Alcoa, a PRP for the site, that required the completion of an RI/FS at the site.  The RI/FS is underway at the site. The Agency evaluated materials reuse options for site bauxite and fluorogypsum.  EPA found that the reuse option was no longer viable.    The Agency created operable unit 1 at the site which addresses the majority of the interior of the site. OU2 will address the soils outside of OU1, and groundwater for the entire site.  The RI/FS for OU1 evaluates the risk and evaluates cleanup options to address the risk.  Alcoa completed focused risk assessments for human health and ecological risk.  Alcoa incorporated those studies into a focused feasibility study report.  A Record of Decision was signed in July 2012 for OU1 which calls for a two foot soil cap over the OU1 area.  The design of this remedy will be completed in September 2013 and cap construction will begin by the end of 2013.  The Agency continues to work with a redevelopment concept for solar energy at the site and a third rail construction project will be built at the site in early 2014.

Community Involvement

The City of East St Louis is a PRP and their staff is intimately familiar with the current site progress and has been communicating the progress through the city council.

Congressional Interest

Congressional involvement at present consists of working with the developer on potential legislation to support the proposed site reuse.

Property Reuse

The Agency and the PRPs are in discussions regarding a potential solar energy redevelopment project.
