The bill establishes a new legal framework under Section 708C.1, which prohibits the intentional emission, injection, release, or dispersion of chemicals or substances into the atmosphere for the purpose of manipulating weather, climate, or sunlight intensity. This prohibition applies to all individuals and corporations within the state of Iowa. Violators of this law will face serious consequences, including being charged with a class D felony. Additionally, corporate officers, directors, or employees may incur civil penalties of up to $100,000 for violations, with each day of non-compliance considered a separate offense.

However, the bill includes an exemption for the aerial application of agricultural inputs such as fertilizers and pesticides, as long as these substances are applied by licensed professionals and do not aim to alter weather or climate conditions. This provision ensures that legitimate agricultural practices are not hindered by the new regulations while still addressing the potential environmental risks associated with weather engineering activities.
