On March 21, 2025, the Indiana Senate introduced Senate Bill 457, a legislative proposal aimed at regulating carbon dioxide sequestration within the state. The bill seeks to establish a framework for the management and monitoring of carbon sequestration projects, addressing both environmental concerns and the growing need for sustainable energy practices.

One of the key provisions of Senate Bill 457 is the establishment of a carbon dioxide storage facility trust fund. This fund will be financed through fees collected from carbon sequestration operations, with the revenue earmarked specifically for the long-term monitoring and management of these projects. Notably, the bill stipulates that any funds remaining in the trust by June 30, 2025, will be transferred to the state general fund, raising questions about the sustainability of funding for ongoing monitoring efforts.

The bill also introduces new regulations regarding drilling near carbon sequestration sites. Mineral owners or lessees are required to notify storage operators at least 31 days prior to drilling within specified distances of carbon sequestration facilities. This provision aims to ensure that drilling activities do not compromise the integrity of the storage facilities, which is critical for the safe and effective sequestration of carbon dioxide.

Additionally, Senate Bill 457 allows for the issuance of permits for nonproduction wells intended for geological investigations related to carbon sequestration. This aspect of the bill is designed to facilitate research and data collection on the suitability of underground formations for carbon storage, which is essential for the development of effective carbon management strategies.

The introduction of Senate Bill 457 has sparked discussions among lawmakers, environmental advocates, and industry stakeholders. Proponents argue that the bill is a necessary step toward addressing climate change and promoting cleaner energy solutions. However, some critics express concerns about the potential risks associated with carbon sequestration and the adequacy of regulatory oversight.

As the bill progresses through the legislative process, its implications for Indiana's energy landscape and environmental policy will be closely monitored. The outcome of Senate Bill 457 could set a precedent for how the state approaches carbon management and sustainability in the years to come.
