A bill for an act relating to water quality standards, including by providing for the regulation of animal feeding operations, providing penalties, and making penalties applicable.

SF 2265 establishes new regulations for animal feeding operations (AFOs) in Iowa to protect water quality. It directly affects medium and large livestock farms (defined by federal standards) by requiring them to obtain federal-style NPDES permits for managing manure and waste runoff. Key provisions include mandating permit requirements for these operations, setting rules for manure storage and application, and defining terms like "effluent" to cover manure, bedding, and other pollution sources. The bill aligns with federal water pollution laws but adds state-specific requirements for AFO management.
