DNR-PORE SPACE COMPENSATION

Summary

SB1500 amends Illinois’ Safety and Aid for the Environment in Carbon Capture and Sequestration Act, specifically the section governing integration and unitization of pore space for carbon dioxide sequestration projects. The bill changes how the Department of Natural Resources (DNR) must determine just compensation for nonconsenting pore space owners when a sequestration operator seeks to combine multiple owners’ interests into a permitted storage area. Under the bill, compensation for a nonconsenting owner must be at least the average total payment package paid to similarly situated consenting owners, rather than being tied to agreements from the prior 365 days alone. The bill also removes language that would have excluded pre-injection incentives from the compensation comparison and removes language that would have required operations-term or injection-term payments to be included in the comparison. In addition, the bill retains and reinforces the broader unitization process: operators must show they have obtained rights from owners covering at least 75% of the surface area above the proposed facility, make good-faith efforts to negotiate with all owners, provide public notice and a hearing, and secure both a federal Class VI well permit and an Illinois carbon sequestration permit before the DNR order becomes effective. It also preserves provisions for compensation to unknown or nonlocatable owners through escrow and unclaimed property procedures, and requires prompt replacement water if monitoring shows drinking water has been rendered unsafe.

Impact

SB1500 would alter the compensation standard in the carbon capture and sequestration statute by broadening the comparison base for nonconsenting pore space owners and by clarifying which components of consenting-owner agreements may be counted in that comparison. This affects sequestration operators, pore space owners, the Department of Natural Resources, and the permitting framework for Class VI carbon storage projects in Illinois. The bill does not change the overall structure of unitization, but it changes how just compensation is measured and could affect project costs, negotiations, and the valuation of pore space rights in carbon sequestration developments.

Sentiment

No committee transcripts or recorded votes were provided, so there is no direct evidence of legislative debate or formal support/opposition in the materials supplied. Based on the bill text, the measure appears to be framed as a property-rights and compensation clarification within the carbon sequestration permitting process rather than a broad policy overhaul. The overall tone of the bill is technical and regulatory, with a focus on ensuring compensation standards for landowners and procedural safeguards for project approval.

Contention

The main point of potential contention is the compensation formula for nonconsenting pore space owners. Supporters of the bill would likely view the change as a fairness measure that better aligns nonconsenting owners’ compensation with the full payment packages received by consenting owners, while opponents may argue it could increase project costs, complicate negotiations, or make carbon sequestration projects harder to develop. Another likely issue is the bill’s treatment of incentives and post-injection payments, since removing those exclusions and inclusion rules changes how comparable compensation is calculated and could affect disputes over what counts as a true market-based payment package.
