The Wisconsin Public Service Corporation (WPSC) now has to pay a $80,000 fine for violating air pollution rules at the utility’s coal-fired plants in Rothschild.
Attorney General J.B. Van Hollen said the utility will pay the fine in forfeitures, court costs and surcharges.
The state Department of Justice said WPSC violated the conditions of its state air pollution control permit, at the utility’s coal-fired power plants in Rothschild.
The civil complaint said the utility exceeded carbon monoxide and volatile organic compounds emissions limits at the plant.
In addition, the complaint said WPSC exceeded sulfur dioxide emissions limits on eight days between July 2008 and April 2009. According to the complaint, the utility also operated without a required pollution control device, possibly allowing emissions of unregulated particulate matter.
The attorney general’s office said particle pollution, ground-level ozone and sulfur oxides can harm public health and the environment.
