A group of lawmakers in the House has unveiled a series of six legislative proposals aimed at imposing stricter regulations on carbon capture pipeline projects within Iowa. The measures, introduced by Representatives Charley Thomson, Helena Hayes, Mark Cisneros, and Cindy Golding, seek to enhance oversight by the Iowa Utilities Commission (IUC) and limit the use of eminent domain for such projects. These actions come amid growing concerns over the Summit Carbon Solutions' proposed pipeline, which would transport carbon dioxide from ethanol plants to storage sites in North Dakota. While the IUC approved Summit's permit in August 2024, construction remains contingent on approvals from other states, including South Dakota, where the project faces significant opposition.

The legislation includes several key provisions designed to address safety and constitutional concerns. For instance, one bill prohibits the IUC from renewing permits for pipelines transporting liquid carbon dioxide, while another allows landowners affected by eminent domain takings to seek judicial review. Additionally, companies seeking hazardous liquid pipeline permits must demonstrate adequate insurance coverage for potential damages. Representative Thomson highlighted that these measures aim to correct perceived errors made by the IUC during its evaluation process, particularly regarding safety and constitutionality issues.

Opponents of the pipeline argue that it poses serious health and safety risks to nearby residents. Dan Tronchetti, a resident of Greene County, emphasized the dangers associated with living in the "kill zone" of an eight-inch pipeline operating at high pressure. Proponents of the project, however, maintain that CO2 pipelines are among the safest methods for transporting and sequestering carbon, citing their proven track record of reliability. Despite previous efforts by House Republicans to pass similar legislation, these bills have struggled to gain traction in the Iowa Senate. Thomson expressed hope that the new legislative session would see progress, noting strong public support for protecting property rights.

The debate surrounding the pipeline has also sparked discussions about economic impacts. Monte Shaw, Executive Director of the Iowa Renewable Fuels Association, warned that halting the project could harm Iowa farmers' ability to compete in low-carbon biofuels markets. Meanwhile, Senate Minority Leader Janice Weiner indicated Democratic support for the legislative proposals and called for Republican cooperation in advancing the measures. House Speaker Pat Grassley suggested that some of the bills might be consolidated into larger packages as the session progresses, expressing optimism about potential Senate consideration of related issues.

As the legislative process unfolds, the focus remains on balancing environmental and economic interests while safeguarding the rights of Iowa's citizens. The coalition's efforts reflect a broader trend of increased scrutiny over large-scale infrastructure projects and their implications for local communities. Moving forward, stakeholders will closely monitor how these bills evolve and whether they can achieve bipartisan support in both chambers of the Iowa legislature.
