HF 2534 adds shellfish to Iowa's definition of "animal" under animal feeding operation (AFO) regulations. It establishes weight-based calculation rules: shellfish weighing 25 grams or more equal 0.001 animal units each, while smaller shellfish equal 0.00006 animal units each. Shellfish confinement operations can now choose to follow general water quality permitting instead of standard AFO requirements. This directly affects shellfish farmers by integrating them into the state's existing AFO regulatory framework.

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 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.

This bill amends Iowa law to require strict liability for individuals or entities in control of hazardous substances. It specifically holds them financially responsible for "excessive and extraordinary" costs incurred by the state or local governments during oversight and monitoring of hazardous conditions they caused. The new provision directly affects businesses and individuals handling hazardous materials, as they may now face additional financial obligations beyond typical cleanup costs. This change focuses solely on monitoring and oversight expenses, not remediation or cleanup costs, which remain governed by existing law.
