MADISON, Wis. (AP) — A new coal-fired power plant in central Wisconsin must limit the visibility of pollutants leaving the smokestack of its main boiler, according to an appeals court.
The court said the Wisconsin Department of Natural Resources erred when it did not include a federal visibility standard on an air pollution permit for the $774 million plant that opened in 2008.
Limiting the visibility of emissions is important because it makes sure lower levels of harmful particulate matter get into the air.
The DNR and the plant’s operator argued the visibility standard wasn’t necessary because the plant controlled emissions in other ways.
The court declined to order the plant to further reduce emissions of sulfur dioxide and nitrogen oxide, saying limits set by the DNR were appropriate.
