The Minnesota Pollution Control Agency has fined dozens of area businesses and individuals for violations that include air and water quality concerns, hazardous waste, and others.

The City of New Ulm was fined more than $4,000 after a generator tested more than three times the upper limit for nitrous oxide emissions. City officials say it was caused by a programming error with the system and was immediately corrected.

Guardian Energy in Janesville was fined $10,000, Central Bi-Products in Redwood Falls over $15,000, and ADM Corn Processing in Marshall more than $17,000. All three are for air quality violations.

More than 70 businesses statewide faced fines totaling over $333,000 during the MPCA’s first quarter enforcement.
