HB3614 amends the Illinois Environmental Protection Act to add a new prohibition on carbon sequestration activities in sequestration facilities that overlie, underlie, or pass through a sole-source aquifer. The bill also defines “sole-source aquifer” by reference to federal Safe Drinking Water Act/EPA designations and the aquifer’s upstream project review area. In practical terms, it would bar carbon dioxide injection and long-term geologic storage projects from being sited in or through these specially protected groundwater areas.
The bill is focused on the state’s carbon capture and sequestration permitting framework. It leaves in place the existing permit and reporting requirements for carbon sequestration activities, but adds an explicit location-based restriction intended to protect drinking water resources. The measure is effective immediately if enacted, and it would become part of the statutory prohibitions governing carbon sequestration facilities and Class VI well-related projects in Illinois.
Impact
HB3614 would amend Sections 59 and 59.5 of the Environmental Protection Act, narrowing where carbon sequestration projects may operate by prohibiting them in sequestration facilities that intersect sole-source aquifers. This would affect project developers, permit applicants, and operators seeking Illinois approval for carbon dioxide capture and underground storage, especially in areas where EPA has designated aquifers as sole-source or principal aquifers. The bill would not eliminate carbon sequestration generally, but it would add a categorical siting restriction on top of existing state permitting, reporting, and integration requirements.
Sentiment
No committee transcripts or recorded votes were provided, so there is no direct evidence of debate or formal support/opposition in the available record. Based on the bill text and caption, the measure appears to be framed as a safety and drinking-water protection bill rather than an anti-carbon-capture bill. The overall tone of the proposal is precautionary, emphasizing environmental protection and groundwater safety.
Contention
The likely point of contention is the balance between protecting sole-source aquifers and allowing carbon capture and sequestration projects to proceed. Supporters would likely argue that underground CO2 storage should be barred in sensitive drinking-water areas because of contamination or leakage risk, while opponents or affected industry stakeholders may argue that the restriction is overly broad, could limit viable project sites, and may hinder carbon reduction and industrial decarbonization efforts. Because the bill creates a categorical ban rather than a case-by-case review standard, the main dispute would likely center on whether the added protection is necessary and whether it could impede CCS deployment in Illinois.
