Caption

A bill for an act relating to animal feeding operations by regulating shellfish, and making penalties applicable. (Formerly HSB 662.) Effective date: 07/01/2026.

Summary

House File 2534 amends Iowa’s animal feeding operation laws to expressly include shellfish within the definition of “animal” for purposes of Chapter 459. It also adds shellfish-specific stocking density provisions, distinguishing between shellfish weighing 25 grams or more and those weighing less than 25 grams. In addition, the bill creates a permitting option for operations that exclusively confine fish or shellfish, allowing those operators to elect to comply with the permitting requirements in Iowa Code section 455B.183 instead of the permitting requirements in the animal feeding operations subchapter. The bill is primarily a technical and regulatory update that brings shellfish operations into the existing framework for confinement feeding operations. By doing so, it affects how certain aquaculture or shellfish confinement facilities are classified, permitted, and regulated under state law. The measure also makes penalties applicable under the amended chapter, meaning shellfish operators may be subject to the same enforcement structure that applies to other regulated animal feeding operations.

Impact

HF 2534 changes Iowa Code chapter 459 by expanding the statutory definition of animal to include shellfish and by adding shellfish-specific animal unit values. It also amends the exception for confinement feeding operations to allow operators that exclusively confine fish or shellfish to choose an alternative permitting path under Iowa Code section 455B.183. The practical effect is to integrate shellfish operations into the state’s animal feeding operation regulatory scheme while preserving a separate permitting option for certain aquaculture facilities and making applicable the chapter’s enforcement and penalty provisions.

Sentiment

The bill appears to have been broadly supported and noncontroversial. It passed the House 89-0 and the Senate 43-0, indicating unanimous approval in both chambers. The available record shows no committee transcript debate, and the voting history suggests the measure was viewed as a straightforward regulatory clarification rather than a contested policy change.

Contention

No notable opposition is reflected in the available materials. Because there are no committee transcripts, there is no recorded dispute over whether shellfish should be treated as animals for this regulatory purpose, whether the new stocking values are appropriate, or whether the alternative permitting option is sufficient. The unanimous votes suggest any concerns, if raised, were resolved before floor consideration or were minimal.
