Wisconsin Public Service has to pay $80,000 for violating air pollution rules.
This all centers around Weston Coal Power Plant 4 in Rothschild. The violations date back several years to 2008.
According to state authorities, WPS violated its air pollution control permit. Now, the fine comes as part of a settlement.
Court documents filed in Marathon County say WPS had five different violations, all relating to air pollution. That includes letting out excessive carbon monoxide, volatile organic compound, and sulfur dioxide emissions.
The state also says WPS failed to use its pollution control device at certain times, and that it didn't continuously monitor emissions some of the time.
WPS doesn't deny the claims. In fact, spokesman Kerry Spees says the company reported them itself.
"They haven't occurred for several years. The processes have been fixed and the plant is operating smoothly," said Spees.
State authorities say these violations could have serious consequences. But in this case, experts say little harm was likely done.
"The impact would have been very minimal," said Jeffery Johnson of the Wisconsin Department of Natural Resources.
According to court documents, WPS has to pay the fine by the end of September.
