The bill establishes a regulatory framework for anaerobic digester systems associated with animal feeding operations in Iowa, focusing on their construction, operation, and management. It introduces new definitions and provisions, including the requirement for construction permits for digester structures, which must be covered, and outlines the conditions under which manure disposal through these systems complies with existing manure management laws. The bill also sets a cap of $250 on permit application fees, which will be deposited into the state’s general fund, and mandates that applicants provide detailed information about the type and amount of digestate produced.

Additionally, the legislation specifies distance requirements for the placement of digester structures to protect air and water quality, and it establishes construction design standards, particularly for areas with karst terrain to prevent groundwater pollution. It requires that any digestate applied to land under a nutrient management plan must include a digestate management supplement detailing nutrient concentrations and application calculations. The bill also includes civil penalties for violations of air and water quality regulations and mandates that the Department of Natural Resources (DNR) regulate these systems until new rules are adopted. Overall, the bill aims to enhance the management of animal waste while promoting the use of anaerobic digestion technology in Iowa's agricultural sector.
