Silver Bay, MN (Northland's NewsCenter) --- Northshore Mining is paying up for having exceedingly high dust levels.
Cliffs Natural Resources has agreed to pay a $240,175 civil penalty to the Minnesota Pollution Control Agency and to increase air measurement practices.
Between the fall of 2010 and spring 2011, dust emission levels were higher than accepted levels five times.
In a statement, the company said it has worked "diligently" to lower dust levels and improve emission suppression efforts.
Air monitoring devices at Northshore's taconite plant indicate that dust levels are below the required limits.
