Emission Rules Approved

The Minnesota Pollution Control Agency board has approved new regulations to curb haze over northern Minnesota.

The state rules are aimed at cutting 30-thousand tons of emissions annually to reduce haze over areas such as Voyageurs National Park and the Boundary Waters Canoe Area that receive special protections under the federal Clean Air Act.

They must still be approved by the U-S Environmental Protection Agency, which has ordered that air over national parks and wild lands should be haze-free by 2064.
