Federal and state environmental agencies have scheduled a discussion Thursday evening about cleanup plans for the badly polluted land along Talleyrand Avenue formerly used by Kerr-McGee Chemical Corp.

Employees of the U.S. Environmental Protection Agency and Florida Department of Environmental Protection will have an “availability session” with exhibits and plan information from 5:30 to 7:30 p.m. at 1606 Walnut St. in Springfield.

The Kerr-McGee property at 1611 Talleyrand Ave. is a federal Superfund site, a seriously polluted area where EPA took over cleanup planning because no one else was getting enough done.

The 31-acre site along the St. Johns River was used to make and distribute fertilizer and pesticides for a series of companies from the 1890s to the 1970s when Kerr-McGee shut it down. Pesticides and metals contaminated the soil and groundwater enough to be dangerous to people and the environment, and the property is fenced off and locked now, with no buildings left standing.
