Animal Feeding Operation Construction Permit

Department of Natural Resources


A permit that authorizes construction of animal feeding operation structures and/or manure and runoff controls. Animal feeding operations can be confinements or open lot facilities. A confinement facility with more than 1000 AU (2500 swine finishing hogs or 1000 head of cattle as an example) requires a construction permit. Any size confinement facility utilizing an earthen pond for manure storage requires a construction permit. An open feedlot greater than 1000 head of cattle and who is applying for a NPDES permit will require a construction permit to build runoff controls.

Code Citation IAC 567 – Chapter 65
