The Livestock Siting Law (s. 93.90 Wis. Stats.) and Rule (Ch. ATCP 51 Wis. Adm.

To obtain a conditional use permit or license in these jurisdictions, new and expanding operations must show that they meet state requirements for waste storage, odor, nutrient and runoff management. What does this mean for nutrient management planners?
