The Kewaunee County Board on Tuesday unanimously passed the local adaptation of new state rules regulating manure spreading on shallow soils.

The rules – NR 151 of the state administrative code – were based on the recommendations of the Department of Natural Resources’ Best Management Practices Workgroup comprised of local farmers, officials and other citizens that were developed in a series of meetings from 2015 to 2017.

The county Land & Water Conservation Department will be responsible for enforcing the rules, which regulate manure spreading on soil that is 0-20 feet deep to bedrock over fragile Silurian dolomite or karst bedrock. The rules are adopted as Chapter 39 of the county ordinance book.

After the revised NR 151 took effect July 1, all farms in the county already must follow them except for concentrated animal feeding operations, the largest farms with 1,000 or more animal units, Land & Water Conservation Department Head Davina Bonness said. CAFOs are regulated under the terms of their individual state wastewater discharge permits, which run for five years.

“This is adopting the state performance standards locally to Kewaunee County, and we’ll have all farms following the same rules that are listed in state law NR 151,” Bonness said.

County Board Chairman Robert Weidner thanked Bonness, who was also part of the state technical committee that drafted the changes in NR 151.

“I’d like to thank you and the committee and all those who worked on this for a long, long time,” Weidner said.
