Manure and Nutrient Plans, Permits and Regulations

This page is designed to provide a comprehensive site for accessing information relating to manure management regulations in Iowa. These regulations are primarily divided into three categories, confinement feeding operations(the term SAFO, small animal feeding operation, only applies to small confinements), open feedlots and combined operations. For best use of this site, you must first determine how your operation is classified and the size of your operation.
In addition to the links to the Iowa Department of Natural Resources Animal Feeding Operations Web page, additional resources from other sources are included. Please make sure when following links to other pages you carefully read the requirements listed on those pages and follow the appropriate links for further information.
IMMAG encourages you to contact the staff in the Animal Feeding Operations Section of DNR or visit the IDNR Animal Feeding Operations Web page for specific questions you may have regarding your animal feeding operation in Iowa and requirements for manure management plans, construction permits, and land application of manure. Please visit the IMMAG Web page regularly for new information regarding new rule packages or subscribe to our monthly email newsletter the IMMAG Update to receive information directly in your inbox.
