U.S. District Judge Rodney Sippel ruled the coal-fired, 1,242-MW Rush Island plant has violated the Clean Air Act, with “significantly more pollution” emitted after modifications.
The ruling could require plant owner Ameren to install additional pollution control equipment at the power plant in Jefferson County, the Associated Press reported.
The U.S. Department of Justice filed suit on behalf of the Environmental Protection Agency in 2011, alleging that upgrades to boilers installed in 2007 and 2010 significantly increased sulfur dioxide emissions. The suit also claimed Ameren should have filed a permit for the upgrades that would have required additional pollution controls.
Ameren plans to appeal.
Ameren Missouri president said in a statement the court “misapplied the law and ignored the evidence presented at trial.”
