The federal and state government filed a civil lawsuit against Midwest Generation for its continual violation of the Clean Air Act.
The lawsuit alleges Midwest Generation made major changes to its coal–fired power plants in Illinois without installing required pollution control equipment.
The company owns six in Illinois including this one in Pekin.
The EPA says the excess illegal emissions are sufficient to cause serious harm to human health and the environment.
The lawsuit was filed in Chicago where the company is headquartered.
