NPL Site Narrative for Clinch River Corporation
CLINCH RIVER CORPORATION
The Clinch River Corporation site consists of approximately 30.5 acres and is located on the banks of the Emory River/Watts Barr Reservoir in Harriman, Tennessee.
Clinch River Corporation operated as a pulp and paper mill from 1929 until 2002. Byproducts of the manufacturing process include spent processing liquids ("black liquor"), coal tar constituents (polynuclear aromatic hydrocarbons or PAHs), and piles of wastepaper.
Historical investigations at the site have revealed extensive contamination in surface and subsurface soil and shallow ground water. Contamination includes elevated concentrations of site-related hazardous substances, including dioxins, furans, PAHs, polychlorinated biphenyls (PCBs), and various metals in surface and sub-surface soil. In addition, site related contaminants have been found in sediment and fish tissue within the Emory River/Watts Barr Reservoir.
Potential Impacts on Surrounding Community/Environment:
Recent investigations suggest that off-site migration from contaminated source areas of dioxins, furans, PAHs and several metals into Watts Barr Reservoir, may have affected the fishery. The Emory River (Watts Barr Reservoir) is used for recreational and subsistence fishing. An estimated 54,750 pounds of fish are harvested annually from the Watts Barr Reservoir. In addition, the Emory River/Watts Barr Reservoir is a habitat for three federally designated endangered mussel species, including the Finerayed pigtoe mussel, Purple bean mussel and the Alabama lamp mussel.
Response Activities (to date):
In September 2011, the EPA conducted an emergency removal at the site. The EPA removed 63 drums of hazardous material, contaminated soil from the drum storage area, and 20,000 gallons of black liquor from the site.
Need for NPL Listing:
The state of Tennessee referred the site to the EPA to allow for a comprehensive cleanup to address all the human health and environmental risks posed by the site. Other federal and state cleanup programs were evaluated, but are not viable at this time. The EPA received a letter of support for placing this site on the NPL from the state.
[The description of the site (release) is based on information available at the time the site was evaluated with the HRS. The description may change as additional information is gathered on the sources and extent of contamination. See 56 FR 5600, February 11, 1991, or subsequent FR notices.]
