DULUTH, Minn. (AP) -- Federal regulators have issued final regulations aimed at reducing pollution from taconite plants that causes haze over northern Minnesota's wild areas including Voyageurs National Park and the Boundary Waters Canoe Area.
The Duluth News Tribune reports (http://bit.ly/13IwPU2 ) the regulations will force some taconite operations to add expensive new equipment to curb nitrogen oxides and sulfur dioxide.
The U.S. Environmental Protection Agency says the plan will cut pollutants that are harmful to people's health and that impair visibility in national parks and wilderness areas. The agency says the rules are expected to reduce nitrogen oxide emissions by about 22,000 tons per year and sulfur dioxide emissions by about 2,000 tons.
The rules affect all six taconite operations in Minnesota as well as the lone taconite operation on Michigan's Upper Peninsula.
