Case Description

The Anniston PCB Site, located in the Coosa River drainage in east-central Alabama, is contaminated with at least 28 hazardous substances, including polychlorinated biphenyls (PCBs). PCBs were manufactured in a facility in Anniston owned and operated by the Monsanto Company (Monsanto) from 1935 to the early 1970s. The trustees for natural resources, the US Department of the Interior, acting through the Fish and Wildlife Service; the State of Alabama, acting through the Geological Survey of Alabama; and the Alabama Department of Conservation and Natural Resources, initiated a natural resource damage assessment (NRDAR) in 2005 under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). Pursuant to applicable regulations, the Trustees invited the potentially responsible party to join in a cooperative assessment, but it declined. The Trustees proceeded to finalize an Assessment Plan in 2010 (See 43 CFR ยงยง 11.30-11.38). Migratory birds, fish and other aquatic organisms, water and sediment have potentially been negatively affected by the release(s) of contaminants at the Anniston PCB site. High levels of PCB contamination have been found in areas surrounding the facility and in and around Snow Creek, Choccolocco Creek, and the Coosa River downstream of the facility. Fish consumption advisories are in place in Choccolocco Creek and a 100-mile reach of the Coosa River, including two major reservoirs providing water-based recreational activities. The Trustees are continuing their Assessment activities, conducting several studies including a supplemental soil and sediment study, several avian studies, and a compilation of mussel resources in the water basin. The assessment work continues, and the Trustees are in the process of identifying additional study needs to understand the extent and duration of facility-related contamination in the environment and its effects on natural resources and associated services. The Trustees are coordinating closely with the EPA in its ongoing efforts to clean up the contamination from the facility.
