HF 2618 repeals Iowa's "smart planning principles" (sections 18B.1 and 18B.2), which required local governments and state agencies to consider 10 specific guidelines in planning, zoning, and development decisions. The bill removes these requirements from state code, eliminating the obligation for cities, counties, and state agencies to reference or apply these principles when creating comprehensive plans, zoning regulations, or infrastructure projects. It also deletes related references from other sections of Iowa law governing regional planning (28I.4), airport zoning (329.3), and local development regulations (335.5, 414.3). This change directly affects how local governments approach land use and development planning across Iowa.

HF 2529 requires manufacturers of farm equipment with diesel exhaust fluid systems to provide owners (farmers, lessees, or licensees) with free diagnostic and repair information, including software updates, on the same terms they offer to their authorized repair providers. It also mandates that manufacturers make replacement parts and diagnostic tools available for purchase at fair, reasonable prices comparable to those offered to authorized repair providers in the same region. The bill does not force manufacturers to disclose trade secrets or override existing agreements, but voids contracts that waive these new rights. This directly affects farmers who operate diesel-powered agricultural equipment requiring emissions control systems.

HF 989 establishes a new regulatory framework for anaerobic digester systems used in animal feeding operations. The bill defines various terms related to these systems, including digester manure, feedstock, and digestate. It grants a state department the authority to create rules for the on-farm construction, expansion, storage, stockpiling, and application of materials associated with anaerobic digesters. These regulations aim to manage organic materials originating from animal feeding operations, and the bill also provides for fees and applicable penalties.

HF 860 prohibits state and local governments from enacting regulations on fuel-powered equipment. Specifically, it prevents these governmental bodies from creating rules based solely on the equipment's fuel source. This means state and local authorities can no longer implement policies that differentiate or restrict machinery because of the type of fuel it consumes.
