Bill Overview
Analyzed Economic Effects
2 provisions identified: 1 benefits, 1 costs, 0 mixed.
Fish and shellfish farms get permit choice
Beginning July 1, 2026, farms that only confine fish or shellfish can choose a different permit path. You can elect the permitting rules in section 455B.183 instead of chapter 459. This choice changes which technical requirements apply and may lower compliance steps or costs.
Shellfish farms now under animal rules
Beginning July 1, 2026, Iowa treats shellfish as animals under animal feeding operation rules. If you confine shellfish, chapter 459 permitting and compliance rules can apply to you. The law sets animal‑unit factors for shellfish: 0.001 each at 25 grams or more, and 0.00006 each under 25 grams. These values count toward permit and threshold calculations for your site.
