The Sierra Club, Citizen Action Coalition of Indiana, Valley Watch and Save the Valley filed a 54-page appeal to the Indiana Office of Environmental Adjudication regarding Duke Energy's planned IGCC plant near Edwardsport, Indiana. The appeal stated that the project's "air permit would allow new air pollution emission sources and increases in air pollution beyond what's legally allowed." Bill Hayden, the chairman of Indiana Sierra Club, said in a statement, "We are taking action today because Duke and the state are threatening Indiana's residents and ratepayers by pushing forward with a coal plant as the rest of the country turns against coal." Duke Energy has not yet seen the appeal so they have not commented on it. This plant, however, would potentially be one of the first in the United States to use carbon capture and storage technology which would limit the emissions and could possibly poke holes in the appeal.
