Current Site Status

The Kerr-McGee Chemical Corp. – Navassa site includes the area where Kerr-McGee Chemical Corporation operated a wood-treating plant until 1980. EPA placed the site on the  National Priorities List (NPL) in 2010 because of contaminated ground water, soil and sediment resulting from facility operations. EPA, the North Carolina Department of Natural Resources and Environment (NCDENR) and Tronox Incorporated (Tronox), the site’s potentially responsible party (PRP), are investigating and taking steps to clean up the site in order to protect people and the environment from contamination. 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. By investigating and cleaning up the site, EPA, NCDENR and the site’s PRP continue to protect people and the environment from site contamination.

Site Location and Background

The 300-acre site is located in Navassa, North Carolina. The southwestern part of the site includes the area where a wood-treating plant operated until 1980. The facility was dismantled in 1980, but significant impacts remain especially in the former ponds and in the tidal wetland on the south end of the site. The former facility also includes a single residential property that not affected by site contamination. A residential area across North Navassa Road and North Navassa Road border the site to the north and west, Sturgeon Creek borders the site to the south and Brunswick River borders the site to the east.

The site is fenced and currently vacant. The Town of Navassa would like to see redevelopment at the site following the completion of cleanup activities.

Investigation and Cleanup Responsibility / Oversight

The state referred the site to EPA in 2003 and EPA entered into an AOC with the Responsible Party, Kerr-McGee, in 2004. Kerr-McGee created Tronox as a spin-off corporation in March 2006.  Tronox assumed responsibility for the cleanup in Navassa.  Kerr-McGee subsequently was acquired by Anadarko Petroleum in August 2006.  Tronox filed for Chapter 11 bankruptcy protection in January 2009.  EPA listed the site on the NPL on April 5, 2010.  The Tronox bankruptcy resulted in the creation of the “Multistate Environmental Response Trust”, which will assume some of the RI activities.

Enforcement Activities

EPA negotiated legal agreements with the site PRP to investigate and clean up the site. In 2011, the PRP relinquished its ownership of the site property and created a Multistate Environmental Response Trust. The Trustee, The Greenfield Environmental Multistate Trust LLC, provides funding and works with EPA and FDEP to clean up the site.

Community Involvement

EPA is working with the community and its state partner to develop a long-term cleanup plan for the site, reflecting the Agency’s commitment to safe, healthy communities and environmental protection. Community engagement and public outreach are core components of EPA program activities.

EPA is conducting a range of community involvement activities at the site to solicit community input and to make sure the public remains informed about site activities throughout the cleanup process. Outreach efforts include public notices, interviews and information meetings.

On July 27, 2011, the North Carolina Department of Public Health hosted a public availability session at Navassa Town Hall to discuss the findings from a draft public health assessment report for the site.
