ST. PAUL, MN (AP) - Environmental groups are challenging Minnesota's plan for reducing haze over Voyageurs National Park and the Boundary Waters Canoe Area.
The federal haze rule says power plants and other industries that pollute the air in those places must reduce pollution by installing best available control technologies.
The Minnesota plan offers more flexibility for power plants. State officials say that will accomplish just as much pollution reduction as mandating specific technologies.
But Minnesota Public Radio News (http://bit.ly/NnLtqc) reports several environmental groups disagree.
Christine Goepfert of the National Parks Conservation Association says under Minnesota's approach, power plants can trade with each other for pollution allowances, leaving no guarantee of improvement.
The Minnesota Pollution Control Agency has said the pollution trading program will clean the air just as well as the haze rule would.
