For already existing confinement feeding operations, most requirements concern manure management and land application. Even small animal feeding operations (500 or less animal unit capacity) must at a minimum:
- retain all manure on site between periods of land application,
- observe land application separation distances,
- report any manure releases and
- correctly dispose of dead animals.
Larger confinement feeding operations (more than 500 animal unit capacity) must also have an approved manure management plan and use a certified manure applicator to apply manure.
For more information about required manure management and other requirements, see the manure management page.
Producers interested in stockpiling dry manure should see the AFO Rules & Regulations page and look for requirements under two new laws:
- House File 735 - Signed by the Governor on April 2, 2009. Effective upon signing. Provides for stockpiling dry manure from confinement feeding operations.
- Senate File 432 - Signed by the Governor on 5/26/2009. Now in effect. This bill has requirements for stockpiling manure from dry bedded confinement feeding operations.
Additional requirements may apply to confinement feeding operations as a condition of a construction permit, including land application restrictions required as part of the Master Matrix operational conditions.
For confinement feeding operations that plan to modify or expand an existing site, or build a new site, see the Construction Requirements to determine the specific regulations that apply.
Owners and operators of small livestock truck washing businesses must apply for a land application permit. Look for the Livestock Truck Wash Land Application Permit Application (DNR form 542-0157) and example permit. Find more information on the DNR’s National Pollutant Discharge Elimination System (NPDES) permits pages.
