Environment (Air Quality)

This bill adds shellfish to Iowa's animal feeding operation (AFO) regulations, defining how shellfish count toward regulatory thresholds. It specifies that shellfish weighing 25 grams or more equal 0.001 animal units (1,000 shellfish = 1 unit), while smaller shellfish (under 25 grams) equal 0.00006 animal units (16,667 shellfish = 1 unit). These definitions apply to existing AFO rules governing water and air quality, permitting, and manure management. The bill directly affects shellfish farming operations by subjecting them to the same regulatory framework as livestock. It does not change penalty amounts but ensures shellfish are included in the animal unit calculations used for compliance.

HJR 3 is a proposed constitutional amendment in Iowa that would add a new right to a clean and healthy environment to the state constitution. It states that every person has the right to pure water, clean air, a stable climate, and ecologically healthy habitats, with the state designated as a trustee responsible for conserving public natural resources (like air, water, and lands) for all people, including future generations. The amendment is self-executing, meaning it would take effect without additional laws, and any state actions infringing on these rights would face strict legal scrutiny. This proposal must now be approved by the next Iowa General Assembly before being submitted to voters for ratification.

This bill amends Iowa's air quality laws to update reporting requirements for greenhouse gas emissions. It changes the annual report due to the governor and legislature to cover emissions from two prior years (aligning with EPA's schedule), and allows the EPA's annual inventory to fulfill this state requirement. The bill also repeals outdated mandates for the Department of Natural Resources (DNR) to create a statewide greenhouse gas inventory and operate a voluntary registry, as federal rules now cover these tasks. These changes primarily affect the DNR and regulated businesses (like major polluters under the federal Clean Air Act) by adjusting their reporting obligations.

HF 191 prohibits the intentional emission of air contaminants within Iowa for the purpose of deliberately altering temperature, weather, or sunlight intensity (geoengineering). It directly affects any entity or individual conducting such emissions in the state, overriding conflicting existing laws. The bill requires the Environmental Protection Commission to adopt implementing rules, including emergency rules for immediate enforcement. Key mechanisms include a clear prohibition on weather-modification emissions and a mandate for the Commission to develop specific regulations under existing rulemaking procedures. The bill focuses solely on preventing intentional atmospheric manipulation, not general air pollution control.
