This bill requires Iowa state agencies to ensure that any passenger vehicle rented or leased with a diesel engine can use biodiesel fuel blended at 20% or higher (B-20). Specifically, it mandates that private vendors must provide manufacturer documentation confirming the vehicle's engine is compatible with B-20 biodiesel before being awarded state contracts. The requirement applies to all new or renewed rental/lease contracts issued on or after July 1, 2026. It extends an existing certification rule currently used for state vehicle purchases to the rental/lease procurement process. The bill does not mandate biodiesel use but ensures state vehicles can utilize this fuel type if chosen.
This bill creates a new Scenic Byways Enhancement Fund in Iowa to support the maintenance and improvement of scenic roads across the state. The fund will be financed through voluntary one-dollar contributions collected from vehicle registration applicants and existing state transfers, with all collected money going to the state treasury except for a small portion counties may keep. The state department of transportation will manage the fund to cover costs for litter prevention, upkeep, and development of scenic routes. The legislation takes effect on January 1, 2027, and requires the department to establish rules for administering the program.
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 2640 prohibits intentionally emitting chemicals or devices into the atmosphere within Iowa for the purpose of altering weather, climate, or sunlight intensity. It requires all Iowa airports open to the public to report monthly (starting October 2026) on aircraft equipped with such devices, including their presence, landings, takeoffs, or refueling. Non-compliant airport projects lose eligibility for state funding, and violations are punishable as class D felonies (up to 5 years in prison) for individuals or $100,000 civil penalties for corporate officers. This bill directly affects airport operators, aviation entities, and any organization using weather-modification technology within Iowa.
HF 2642 (Iowa) creates new rules for disposing liquid waste from native distilleries and changes water permit processes. It requires the Department of Natural Resources to establish standards for land application of distillery waste, considering waste volume, disposal method, and per-acre daily rates. The bill removes a categorical definition of "beneficial use" for water permits and instead mandates case-by-case department reviews for permit approvals, with strict 90-day (new) and 30-day (renewal) processing deadlines. This directly affects Iowa distilleries holding class "A" native distilled spirits licenses. The law aims to standardize waste disposal while shifting water permit decisions from category-based rules to individual assessments.
This bill requires Iowa's Department of Administrative Services to create a master contract for government entities to purchase fire fighting foam made primarily from soybean-based materials, excluding harmful chemicals like PFAS (perfluoroalkyl substances). It directly affects all state agencies and local governments that buy fire fighting foam, mandating they use this specific contract unless an exception applies. Local governments with fire departments must decide by January 1, 2027, whether to adopt the soybean-based foam through a new ordinance. The policy shifts procurement away from foam containing toxic fluorinated chemicals, prioritizing safer alternatives.
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 2511 requires Iowa's Flood Center to develop a statewide resilience plan by December 2028, coordinating with state agencies like Homeland Security, Agriculture, and Natural Resources. The plan must include a risk assessment for flooding and water supply changes, an inventory of critical infrastructure (like hospitals, roads, and water systems), and a method to prioritize resilience projects. It directly affects state agencies responsible for implementing the plan and local communities by guiding how state funds address flood risks and natural hazards. The bill mandates biennial progress reports to the governor and legislature to track implementation of the plan's recommendations.
