A bill for an act regulating the application of manure originating from an animal feeding operation, and making penalties applicable.

This bill regulates how manure from animal feeding operations (including both confinement operations storing liquid manure and open feedlots) can be applied to land. It requires manure to be injected or incorporated into soil within 24 hours of surface application, prohibits application on saturated, snow-covered, or frozen ground except during specific emergencies, and bans spray irrigation without dilution rules. During emergencies (like storage failures), operators must follow pre-approved protocols, contact the department, apply only on land with low phosphorus risk, and block drain tiles for two weeks. These rules directly affect farmers and ranchers operating animal feeding facilities in Iowa who manage manure application.
