Environmental Groups Sue Minnesota Over Minntac Mine Discharges
Minntac mine near Mountain Iron
Three environmental groups have sued the state of Minnesota, accusing it of letting North America’s largest taconite mining operation pollute lakes and streams for decades.
The tailings pit at the Minntac mine near Mountain Iron is owned by U.S. Steel. It operates under a state permit that expired 24 years ago. The permit has not been updated with standards to protect water, wildlife, and wild rice.
The Associated Press reports that the lawsuit, filed Wednesday, alleges the pit’s discharges violate water pollution laws and killed wild rice that once thrived nearby.
A Minnesota Pollution Control Agency spokesman says the agency cannot comment.
The MPCA has held off on updating Minntac’s permit until it creates a revised sulfate standard for protecting wild rice, and expects to finish the work in 2018.
