The Northwestern reports non-profit groups have filed a lawsuit in an attempt to revoke permits approved by the state for Richfield Dairy.

Friends of the Central Sands, Family Farm Defenders and others filed the lawsuit Friday in Dane County. The lawsuit asks for a contested case hearing in response to permit approvals by the Wisconsin Department of Natural Resources for high-capacity wells at the dairy and a Wisconsin Pollution Discharge Elimination System permit.

Groups who filed the lawsuit are concerned with the environmental impact of the 4,300-animal dairy.

Family Farm Defenders also filed a lawsuit in July after the DNR approved plans and specifications for the dairy. The lawsuit resulted in DNR’s reconsideration of the high-capacity wells which were ultimately approved.

The lawsuit will not affect construction plans for the dairy which is expected to begin operation in late 2012 or early 2013.
