Current Site Status

Solutia Inc., the Potentially Responsible Party (PRP), under an Environmental Protection Agency (EPA) Administrative Order on Consent (AOC), (Docket No. III-2001-0004-DC)(Order), has agreed to perform work deemed necessary by the EPA at the Solutia AES Property Site in Putnam County, West Virginia. EPA has received the Response Action Plan (“RAP”), prepared by Potesta & Associates, Inc. (“POTESTA”), on behalf of the PRP. The work specified in this Order includes the development and submittal to EPA for approval of a cover/cap design for the site property. This cap will preclude all direct contact with on-site soils, and will consider existing soil sampling data to enable definition of the depth and type of cap media to be utilized. Installation of the cap will not preclude EPA from performing additional area-wide investigative work which may further the characterization of the nature, concentration, extent and depth of dioxin contamination related to the Kanawha River area wide assessment. EPA’s Pre-Remedial Program is concurrently conducting a Site Investigation (SI) to determine the site’s eligibility for the NPL.

Site Description

The Solutia AES Property Site is a flat, 3-acre property located south of Interstate 64 near the Kanawha River in Nitro, Putnam County, West Virginia. There are no buildings on the site; however, there are several areas containing portions of concrete foundations as well as areas of collected construction debris. The site was formerly part of a munitions plant that operated in the 1920's. It was owned briefly by Monsanto Company in the 1970's and subsequently sold to AES. Solutia Inc. purchased the property from AES, Inc in 1999.

Site Responsibility

This site is being addressed by a Potentially Responsible Party under an EPA Superfund Removal Order.

NPL Listing History

This Site is not on the National Priorities List (NPL).

Threats and Contaminants

EPA was requested to respond to the site after the West Virginia Department of Environmental Protection (WVDEP) reported that 14 buried, deteriorating drums were unearthed on the site. Analytical data from a composite sample from several of the drums indicated that they contained dioxin. Four additional areas at the site containing buried drums and or/containers were also later identified. EPA determined that a threat to public health or welfare or the environment existed due to the release or threat of release of dioxin at the site.

Cleanup Progress

In early 1998, a preliminary investigation of the site was conducted by EPA’s contractor to determine if dioxin was present in surface and/or subsurface soils. Analytical results confirmed previous WVDEP findings and revealed that concentrations as high as 4.26 parts per billion of dioxin were present at the site.

On June 14, 1999, Solutia’s environmental contractor, Potesta & Associates, Inc., performed their initial SI. This investigation was designed to evaluate and sample surface soils (0 to 6 inches) for dioxin. This sampling event confirmed concentrations as high as 6.4 parts per billion of dioxin present in soils.
