A bill for an act relating to animal feeding operations, by providing for the regulation of anaerobic digester systems, providing fees, making penalties applicable, and including effective date and applicability provisions.

This bill regulates on-farm anaerobic digester systems used to process manure and organic materials from animal feeding operations. It defines key terms like "digestate" (nutrient-rich byproduct) and "digester feedstock" (organic materials processed in the system), and requires these systems to be linked to the farm via common ownership or adjacency (within 1,250 feet). The Iowa Department of Agriculture must create rules for constructing, operating, and applying digestates, with fees based on the number of structures. The bill applies only to on-farm systems and modifies existing manure disposal regulations to align with this new framework.
