Legislative bill overview

HSB 66 (renumbered HF 881) establishes strict liability for persons in control of hazardous substances in Iowa, meaning they can be held legally responsible for damages caused by those substances regardless of fault or intent. The bill has advanced through committee with unanimous support (20-0 vote) and received a subcommittee recommendation for passage with amendments.

Why is this important

Strict liability laws shift the burden of proof significantly—plaintiffs no longer need to prove negligence or wrongdoing, only that a hazardous substance caused harm. This affects industrial operations, waste management facilities, transportation companies, and property owners who handle or store hazardous materials, potentially increasing their insurance costs and legal exposure.

Potential points of contention

  • Business liability concerns: Industries argue strict liability creates unfair financial burden for accidents beyond their control, potentially driving up operational costs and insurance premiums
  • Scope ambiguity: The bill's definition of "hazardous substances" and "control" could be interpreted broadly, creating uncertainty about which activities and entities are covered
  • Causation and damages: Questions remain about how courts will determine causation and calculate damages when multiple parties or environmental factors are involved
