About the Former Kerr-McGee Site in Columbus, MS

The Site is located at 2300 14th Avenue North, and consists of two parcels separated by 14th Avenue North. The former Main Plant Site occupies 45 acres south of 14th Avenue North. The 44-acre Pine Yard is located north of 14th Avenue North.

In 1928, the T.J. Moss Tie Company started wood treating operations at the Site. Wood treating ended when the Kerr-McGee plant shut down in 2003.

During operations, raw timber was brought to the Site by rail and stored in the Pine Yard and at several locations at the Main Plant.  Creosote, pentachlorophenol and other chemicals were used to pressure-treat the raw timber for use as railroad ties and other wood products.

The wood treating operations released creosote and other hazardous materials into the soil, stormwater ditch sediment and groundwater on and off the Site.
