A group of Kewaunee County families is challenging the Wisconsin Department of Natural Resources decision to renew a wastewater discharge permit for Kinnard Farms Inc. The nonprofit group Midwest Environmental Advocates filed a legal action Oct. 15 asking for an administrative hearing on Kinnard’s Wisconsin Pollutant Discharge Elimination System (WPDES) permit, which was the subject of a May 23 public hearing. The five-year permit was issued Aug. 16 and effective Sept. 1.
