A BILL FOR AN ACT to amend the Indiana Code concerning natural and cultural resources.
Summary
House Bill 1222 would amend Indiana’s dam-regulation statutes to expressly exclude retention ponds from the chapter governing dams. It adds a statutory definition of “retention pond” as a manmade basin designed to collect and store surface water in an impervious membrane liner and not connected to a natural river, stream, or lake. The bill also makes a conforming change to the existing exemptions in the dam chapter so that retention ponds are listed among the structures not subject to those regulations.
The bill keeps the current framework for certain small or low-risk structures, including some erosion-control, livestock, recreation, and wildlife structures, and it preserves application of the chapter to structures on the roster of low head dams. Its effective date is July 1, 2026. In practical terms, the measure would narrow the reach of state dam oversight by removing a category of stormwater or drainage infrastructure from dam permitting and regulatory requirements.
Impact
HB1222 would amend Title 14 of the Indiana Code, specifically IC 14-8-2 and IC 14-27-7.5, by creating a new definition of “retention pond” and exempting those facilities from the state dam-regulation chapter. This would reduce regulatory obligations for owners, developers, and local entities that construct or maintain qualifying retention ponds, while leaving other dam and low-head-dam oversight intact. The bill would not eliminate dam regulation generally, but it would clarify that certain engineered water-retention basins are outside the dam program.
Sentiment
No committee transcript or vote record was provided, so there is no direct evidence of debate, support, or opposition in the available materials. Based on the bill text alone, the measure appears technical and targeted rather than controversial, aimed at clarifying the scope of existing dam law. The absence of recorded votes or discussion prevents a reliable assessment of legislative sentiment beyond the bill’s neutral, administrative character.
Contention
The main point of potential contention is whether retention ponds should be treated like dams for regulatory purposes. Supporters would likely view the bill as a clarification that prevents overregulation of engineered stormwater facilities, while opponents could be concerned that exempting retention ponds may reduce safety oversight or create gaps if a structure functions similarly to a dam. Another possible issue is the precision of the new definition, especially the requirement that the basin be lined with an impervious membrane and not connected to natural water bodies, which could affect how borderline structures are classified.
