We invite you to comment on the draft permit for Spronk Brothers III Real Estate (Mike Spronk Site) animal feedlot located in Rock County.

The facility will house 5,000 head of swine in total confinement barns. Liquid manure generated by the animals will be stored within concrete lined storage structures. Manure generated at the facility will be applied to surrounding cropland at agronomic rates.

This permitting action includes proposed construction and expansion of an animal holding area and liquid manure storage area at the facility. The animal unit (AU) capacity will be increased from 600 AU to a final total of 1,500 AU.

This permit requires the facility to be designed, operated, and maintained to prevent discharge to waters, except in an extreme storm event. Operators are required to land apply manure at agronomic rates, observe water setbacks, and maintain records of land application activities, including location, timing, and rate of application. Please refer to the draft permit for additional requirements.
