A mining business was fined almost $300,000 for improper hazardous waste disposal. A dairy farmer dumped wastewater into a municipal storm sewer. A power plant burned more than 22,000 tons of wood treated with formaldehyde and other resins.
These are some of the 143 violations cited by the Minnesota Pollution Control Agency in the second half of 2012. The number of cited violations doubled from the previous six months.
I looked at the MPCA's enforcement actions for air, water, hazardous waste and other violations. The agency issued nearly $1.3 million in fines and orders for environmental projects, down from $1.4 million in the first half of last year.
Following are the 12 violators that paid more than $10,000 in penalties. All of the businesses consented to the agency's orders. Most were required to take corrective action.
Northshore Mining Co., Silver Bay, fined $292,973 for solid waste/hazardous waste violations
Northshore Mining sprayed 39,200 gallons of a "corrosive hazardous waste leachate" over its Lake County coal-ash landfill to control dust and improperly sent an equal amount to a nearby water-treatment plant, exceeding permitted levels.
It is the fourth time since 2010 that the taconite company has been fined for violating Minnesota pollution laws.
The company failed to immediately report the violations and failed to properly monitor pH levels in the leachate.
Of the total penalty, $50,000 was donated to the Western Lake Superior Sanitary District for renovation of a hazardous-waste collection site.

Northstar was acting as general contractor for the resurfacing of Hwy. 11 near Birchdale and the construction of bridges and culverts near streams, drainage areas and the Rainy River in 2010.
The contractor discharged "excessive amounts of construction-related sediment to surface water," polluting waterways and damaging fish and wildlife habitat.
Acuity Brands Lighting Corp., doing business as Winona Lighting, Winona, fined $99,500 for air quality violations
The company operated as many as five paint spray booths, a sandblasting unit and a degreaser, installed between 1978 and 2000, without proper environmental permits. The company improperly stored and transported hazardous waste.

While working on two bridges over the Rum River near Princeton, Minn., in 2010, Lunda failed to have adequate erosion-control measures in place. The violations allowed sediment-laden storm water to wash into the river.
