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 establishes regulations for on-farm anaerobic digester systems used to process manure and organic waste from animal feeding operations. It defines key terms like "digestate" (nutrient-rich material after processing) and "digester feedstock" (organic materials used in the system), requires these systems to be linked to the farm they serve (via common ownership or adjacency), and gives Iowa's Department of Agriculture authority to create detailed rules for construction, operation, and manure storage. The rules apply only to farm-based systems, not commercial facilities, and clarify how manure processing through these systems meets existing disposal requirements. Farms using anaerobic digesters must comply with these new standards for building and operating their systems.
