In March 2002, an inspector from West Virginia’s Department of Environmental Protection (WVDEP) Hazardous Waste group discovered a waste material on the riverbank of the Kanawha River while doing riverbank inspections.  A shallow slide near the toe of the riverbank exposed a thin lens of discolored material that was intermingled with a black tar-like residue.  The new release was located outside the fenced limits of the production facility, which required an expedited containment and remediation plan.  Solutia addressed the new release under the existing Resource Conservation and Recovery Act (RCRA) Corrective Action permit, with oversight of both EPA and WVDEP, by installing a containment structure in the Kanawha River to prevent migration of contaminants during removal, completing test pits to determine the extent of the material on the bank, and excavating the contaminated material from the area.
