Dover Chemical Corporation has agreed to fund and implement natural resource restoration and protection projects to resolve alleged state and federal natural resource damages associated with the Dover Chemical Corporation Superfund Site and the surrounding assessment area in Dover, Ohio.  The proposed consent decree was lodged by the Justice Department on behalf of the Department of Interior’s Fish and Wildlife Service, together with the Ohio Attorney General’s Office, on behalf of the State of Ohio and the Ohio Environmental Protection Agency. The proposed consent decree is not related to the cleanup of the EPA Superfund Site located where the plant operates. 

The U.S. Fish and Wildlife Service and Ohio Environmental Protection Agency are the Natural Resource Trustees for the site (Trustees).  Together, the Trustees prepared a draft Restoration Plan and Environmental Assessment for the Sugar Creek Valley Natural Resource Damage Assessment at the Dover Chemical Corporation Site (draft RP/EA) that describes proposed restoration actions in the negotiated settlement. The draft RP/EA is available for public review and comment until November 2, 2022.  Written comments may be mailed or emailed to Brian Tucker or Deborah Millsap:

Brian Tucker, DERR, Ohio EPA 50 W. Town St., Ste. 700, P.O. Box 1049 Columbus, OH 43216  or Brian_tucker@epa.ohio.gov

Deborah Millsap, U.S. FWS  4625 Morse Road, Suite 104 Columbus, OH 43230  or deborah_millsap@fws.gov

Comments must be received by November 2, 2022 to be considered. The Trustees will consider and respond to public comments in preparing and issuing a Final Restoration Plan/Environmental Assessment. Once the Consent Decree and the RP/EA are finalized, Dover Chemical Corporation will be required to fund and implement the approved restoration projects.

Overview

The Trustees for natural resources conducted a Natural Resource Damage Assessment and Restoration (NRDAR) for the Dover Chemical Corporation Site (Site). The Trustee agencies are the Department of the Interior (DOI) through the U.S. Fish and Wildlife Service (Service) and the State of Ohio through the Ohio Environmental Protection Agency (Ohio EPA). In the NRDAR, the Trustees determined the amount of restoration required to make the public whole for losses to natural resources due to releases of hazardous substances.

The Site occupies approximately 60 acres on the east bank of Sugar Creek, approximately 1 mile above the confluence with the Tuscarawas River in east central Ohio. The facility has been in production since 1949, producing chlorinated organic compounds, including dichlorobenzene, trichlorobenzene, tetrachlorobisphenol A, and dihydroxybenzophenone by-products (later replaced with chlorinated paraffin by-products). Decades of spills and improper disposal activities have resulted in severe contamination of Site soils, ground water and surface waters of Sugar Creek (including floodplain soils and sediments) by hexachlorobenzene, dioxins and other materials. Fish and wildlife in Sugar Creek and surrounding habitat have been injured by the hazardous substances.
