After several delays, the U.S. Environmental Protection Agency on Wednesday released new air pollution regulations for a half-dozen taconite facilities in Minnesota and a lone operation on Michigan’s Upper Peninsula, the Duluth News Tribune reports. The rules set limits on nitrogen oxide and sulfur dioxide emissions.

The 200-page plan is designed to "reduce pollutants that are harmful to people’s health and impair visibility in national parks and wilderness areas," like the Boundary Waters Canoe Area Wilderness and Voyageurs National Park

WDIO reports some plants will also be forced to install and operate continuous air emission monitoring systems.

Federal officials stepped in last summer after regulators felt guidelines put in place by the Minnesota Pollution Control Agency would not do enough to curb the haze building over northeastern Minnesota.
