The Kerr-McGee Chemical Corp – Navassa site is located in Navassa, North Carolina. It includes the area where Kerr-McGee Chemical Corporation operated a wood-treating plant from 1936 to 1980. EPA placed the site on the Superfund program’s National Priorities List (NPL) in 2010 because of contaminated groundwater, soil and sediment caused by facility operations. Site contamination does not currently threaten people living and working near the site. A water line connects residences and businesses to the public water system.
Site Location and History
The 251-acre former facility is located in Navassa, North Carolina. The upland area of the facility is about 150 acres, owned and managed by the MST, and about 90 acres of marsh became property of the State of North Carolina in the 1990s. Wood-treating operations generated wastewater that was disposed in ponds on site and wastewater discharged into the marsh on the south end of the facility. In 1980, Kerr-McGee removed equipment, buildings and storage tanks from the site and emptied on-site wastewater ponds.
Most contamination is on the southwestern portion of the former facility in the former process area and in the wetland south of the former process area. The adjacent property to the north is a former fertilizer plant and boat factory. Residential properties are across North Navassa Road to the west. Sturgeon Creek borders the site to the south. Brunswick River borders the site to the east.
The EPA and State are working with an Environmental Response Trust (The Greenfield Environmental Multistate Trust LLC) to investigate the Site and plan the cleanup. The Remedial Investigation will be complete in 2017. The EPA, State and Trustee will determine the cleanup strategy in 2018. The site is physically stable with vegetation in place to prevent erosion.
The state referred the site to EPA in 2003 and EPA entered into an Administrative Settlement Agreement and Orders on Consent with Kerr-McGee in 2004. Kerr-McGee created Tronox as a spin-off corporation in March 2006. In 2006, EPA and Tronox entered into an Agreement to conduct a remedial investigation and feasibility study at the site under the Superfund Alternative Approach. EPA and Tronox completed the initial phases of a remedial investigation. Tronox filed for Chapter 11 bankruptcy protection in January 2009. EPA listed the site on the NPL in April 2010. The Tronox bankruptcy resulted in the creation of the Multistate Environmental Response Trust. The Multistate Environmental Response trust is conducting the remedial investigation and feasibility study activities.
EPA is the lead agency on the investigation and cleanup, with the North Carolina Department of Environmental Quality (NCDEQ) as the support agency. The cleanup and management of the property is conducted by the Multistate Environmental Response Trust (MST), an entity created by the Bankruptcy Settlement Agreement of Tronox LLC in 2011. By investigating and cleaning up the site, EPA, NCDENR and the Multistate Environmental Response Trust continue to protect people and the environment from site contamination.
The only potential risks to exposure at the site is to trespassers who contact contaminated groundwater, soil or sediment. The most contaminated areas, the former wastewater ponds and process area, are fenced off to restrict access.
The North Carolina Department of Health and Human Services prepared a document entitled "Public Health Assessment 2012". http://epi.publichealth.nc.gov/oee/hace/docs/KerrMcGeePHA.pdf For more information about health issues, please contact North Carolina Department of Health and Human Services at (919) 733-5900.
Community outreach activities include quarterly community meetings in Navassa. The Multistate Trust has invited community stakeholders to join in a “Redevelopment Working Group” to evaluate redevelopment early in the cleanup planning process. The EPA established a site information repository at Navassa Town Hall, 334 Main St, Navassa, North Carolina.
