The primary method by which mercury is released into our environment is atmospheric deposition, the primary source of which is coal burning power generation plants. Minnesota Power states that construction of the Arrowhead line will reduce mercury emissions by 2.4 pounds annually through decreases of line loss with resulting decrease in generation.

In the immediate vicinity of the powerline there are many recreation areas, including Fond du Lac, Merritt, Magney, Short Line parks, the Willard Munger and Western Waterfront Trails and a snowmobile trail, and the privately owned Buffalo house Restaurant, Bar, and Campground. Minnesota Power incorrectly stated that the line would not be visible from any recreation area. Minnesota Power did not conduct any visibility study because it did not believe it was prudent to do so. There are several mines or quarries near the powerline route, but Minnesota Power states that there are no active mines in the area. Minnesota Power did not address whether the line would have an impact on future aggregate mining in the area.
