EPA's Dioxin Science Plan United States
Environmental Protection Agency
The U.S. Environmental Protection Agency is currently addressing several issues related to dioxins and dioxin-like chemicals in the environment.
To move forward with these efforts, EPA Administrator Lisa P. Jackson requested that a clear plan, with definite timelines, be developed.
On May 26, 2009, Administrator Jackson announced EPA's science plan for dioxin activities in the agency.
