On May 1, 2012, the U.S. Department of Justice opened a 30-day public comment period on a proposed settlement with E.I. du Pont de Nemours and Company for natural resource damages at the Waco Subsite of the Cherokee County NPL site in southeastern Kansas. The proposed settlement is embodied in a Consent Decree that was lodged with the U.S. District Court for the District of Kansas on April 19, 2012.

Under the proposed settlement in the lodged Consent Decree, E.I. du Pont de Nemours and Company will:
Written comments regarding the lodged Consent Decree must be received by the Department of Justice’s Environment and Natural Resources Division by Thursday, May 31, 2012.
