SSB 3119: A bill for an act relating to animal feeding operations by regulating shellfish, and making penalties applicable.

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.

SF 338: A bill for an act relating to duties of the department of natural resources related to air quality including reporting requirements, certifications, data gathering, and rules references.

This bill modifies the duties of the Department of Natural Resources (DNR) concerning air quality. It adjusts the timeframe for DNR's annual greenhouse gas emissions report to align with federal EPA inventories and allows the federal report to fulfill this requirement. The bill also updates administrative rule references for air emission and operating permit fees. Furthermore, it repeals state mandates for DNR to create a greenhouse gas inventory and a voluntary registry, and removes a provision requiring rules for solid waste incinerator operator certification.

HJR 3: A joint resolution proposing an amendment to the Constitution of the State of Iowa relating to the right of the people to a clean environment.

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.

SSB 1101: A bill for an act relating to duties of the department of natural resources related to air quality including reporting requirements, certifications, data gathering, and rules references.

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.

HSB 103: A bill for an act relating to duties of the department of natural resources related to air quality including reporting requirements, certifications, data gathering, and rules references.

This bill updates Iowa's Department of Natural Resources (DNR) air quality reporting requirements. It changes the annual greenhouse gas emissions report to cover emissions from two prior calendar years (aligning with EPA's schedule) and allows the EPA's annual inventory to fulfill this state requirement. The bill also removes outdated references to administrative rules and repeals provisions requiring the DNR to create a voluntary greenhouse gas registry and certify solid waste incinerator operators. These changes primarily affect the DNR's reporting duties and regulated facilities subject to emission fees.

HF 191: A bill for an act relating to the intentional emission of air contaminants into the atmosphere.

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.

HF 847: A bill for an act relating to duties of the department of natural resources related to air quality including reporting requirements, certifications, data gathering, and rules references.

HF 847 modifies the duties of the Iowa Department of Natural Resources (DNR) related to air quality. It adjusts the state's annual greenhouse gas emissions reporting by aligning the timeframe with federal EPA inventories and allowing the federal report to satisfy state requirements. The bill also updates administrative code references for air emission and operating permit fees to reflect current regulations. Additionally, it repeals state mandates for the DNR to create a separate greenhouse gas inventory and a voluntary registry, and removes a provision for solid waste incinerator operator certification rules.
