EPA to hold a public meeting on revised proposed plan for the Kerr-McGee Chemical Corporation Superfund Site
COLUMBUS, Mississippi (July 24, 2025) – On Wednesday, August 6, 2025, U.S. Environmental Protection Agency (EPA) will hold a public meeting to provide information on a revised proposed plan that allows community-supported reuse of the Kerr-McGee Chemical Corporation Superfund Site.
The proposed remedy involves removing surface soil, which was contaminated with creosote and other hazardous materials when the site was used for wood-treating operations. It also calls for the disposal of the contaminated surface soil, backfilling the areas with clean soil and restoring the site.
In 2023, the EPA released a combined proposed plan for Operable Unit 3 (OU-3) and Operable Unit 5 (OU-5). During the comment period, the community requested an alternative for OU-5. EPA issued a separate Record of Decision (ROD) for OU-3 in 2024. This revised proposed plan addresses the remedy for OU-5, which will have its own ROD.
This preferred cleanup approach works to protect human health and the environment while allowing for community-supported reuse of the property within OU-5.
WHEN: Wednesday, August 6, 2025, 6–8 p.m. CT
WHERE: Genesis Dream Center, 1820 23rd St. N., Columbus, MS 39701

The 30-day public comment period is open from July 25 to August 25, 2025. Comments should be sent to Hassanein.Ahmad@epa.gov.
The proposed plan and other site documents are available at epa.gov/superfund/kerr-mcgee-chemical-columbus.
Background:
The 90-acre Kerr-McGee Chemical Corporation Superfund Site is located at 2300 North 14th Avenue in Columbus, Mississippi. The site includes the area where Kerr-McGee, and its predecessors and successors, conducted wood treating operations that released creosote and other hazardous materials into the soil, sediment and groundwater. EPA added the site to the Superfund National Priorities List in 2011 and has completed several cleanup actions.
Pursuant to the 2011 Tronox bankruptcy settlement, the Greenfield Environmental Multistate Trust LLC is conducting environmental actions at the site with oversight from EPA and Mississippi Department of Environmental Quality.
