Northshore Mining Co. recently agreed to pay a $26,087 civil penalty to the Minnesota Pollution Control Agency for alleged water quality permit violations at its Peter Mitchell taconite mine near Babbitt.

PCA officials announced the fine Tuesday, saying the company also must adhere to a schedule to resolve remaining violations at the mine.

Northshore's water emissions permit requires the company to sample effluent from pump-out locations to ensure it is clean enough to meet its permit limits. According to the PCA, the violations occurred between October 2009 and March 2011. The most frequent violation was for failing to meet pH requirements in the water at four mine pump-out monitoring stations. Other violations included suspended solids, ammonia level and biochemical oxygen demand.

The agreement requires the company to investigate and install technologies that will adjust pH levels from water leaving the mine and to take corrective actions if additional violations occur.

Northshore, operated by Cliffs Natural Resources, has a mine in Babbitt and processing center in Silver Bay.
