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 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.
