EPA released a proposed plan for the 21.6 acres called Operable Unit 1. In 2020, after receiving additional input from Navassa, EPA and NCDEQ decided to evaluate Operable Unit 1 for unrestricted residential land use. Additional sampling was conducted in August 2020 to evaluate risks based on unrestricted residential land use, according to the 2020 fourth quarter update. EPA plans to issue a new OU1 Proposed Plan this year to replace the 2019 Proposed Plan and address a smaller, 20.2-acre OU1 area.

From 1936 to 1974, Kerr-McGee and other companies used 70 acres of the 246-acre former Kerr-McGee property for creosote-based wood treating. The property is bordered by the Brunswick River, Sturgeon Creek, a residential area and a light industrial area. The soil, sediment and groundwater are contaminated by creosote-related chemicals, according to the state.

The site was conveyed to Tronox in 2005, a Kerr-McGee spinoff that filed for bankruptcy protection in 2009. In 2011, the acquired about 152 acres, two more acres were purchased later, of the former Kerr-McGee Property as a court-appointed trustee as part of the Tronox bankruptcy settlement. The Multistate Trust is working with its beneficiaries, NCDEQ and EPA, on the site investigation, remediation and redevelopment planning.
