Case Description

The South Charleston Facility and Kanawha River site is located on both the southern bank and Blaine Island of the Kanawha River in West Virginia. As part of an ESA Sect 7 consultation, the owner of the facility, Union Carbide Corporation (UCC) conducted mussel surveys in 2018 and 2019 in the Kanawha River. These surveys discovered federally listed and proposed species in this location for the first time. Also in 2018, UCC discovered that non-aqueous phase liquid (NAPL) was being released from their site into the river. In its capacity as a trustee for natural resources, the State of West Virginia (acting through its Department of Environmental Protection (WVDEP) and Division of Natural Resources (WVDNR)) and DOI (acting through FWS) initiated a NRDAR in summer 2021 (See Preliminary Assessment Screen and Determination and Notice of Intent to Conduct a Natural Resource Damage Assessment). For the assessment phase, the Trustees anticipate focusing on mussels and other aquatic organisms. As part of the NRDA, FWS conducted a 12-week mussel toxicity test using sediment samples collected from the site as well as upstream. The U.S. Environmental Protection Agency is conducting a corrective action under the Resource Conservation and Recovery Act (RCRA) at the facility. The Trustees are closely coordinating with EPA and the ongoing Section 7 consultation for federally listed mussels.
