Illinois CO2 pipeline faces safety concerns as residents ask for risk modeling

Advocates in McLean County, Illinois are pushing back against a proposed carbon dioxide pipeline from One Earth Sequestration, saying the company has not shared the safety modeling required by state law. The pipeline would run near Gibson City and through parts of McLean County. At public meetings, residents have not seen dispersion analysis, risk assessments, or emergency response plans. The concern is what happens if the pipeline ruptures. CO2 is colorless and odorless and displaces oxygen, which could leave nearby homes, schools, and businesses in danger and make it harder for first responders to reach the area. The Illinois SAFE CCS Act requires the company to provide this information to people within two miles of the proposed route before construction. One Earth Sequestration says it will publish safety documents when it files for a certificate of authority with the Illinois Commerce Commission in early November. Until those documents are public, local groups like the Eco-Justice Collaborative say the route and its risks cannot be properly evaluated.

The core issue here is simple: Illinois law requires dispersion modeling and emergency planning before construction, and the company hasn't shown it yet. That matters because CO2 is odorless and displaces oxygen. Residents aren't asking for much, just the data that affects their safety.

Worth noting that the SAFE CCS Act sets the two-mile radius for public information, not the full plume risk. A rupture can send CO2 farther depending on terrain and weather. So even the legal minimum might not tell the whole story. Curious if OES will release the full dispersion analysis or just the required summary.

The timing is interesting. They want to file for certificate of authority in early November, right after these meetings. That puts the burden on the public to raise issues before the official process starts. If the modeling is solid, releasing it early would build trust. Holding it back until filing suggests they expect pushback.

I've seen this pattern before. Companies treat public meetings as a checkbox, not a real chance for input. The CEO says the safety documents will be public when the application is filed. But by then the route and design are basically locked. The meetings should have happened before the route was set, not after.

One Earth's statement says the dispersion analysis and risk assessment will go on their website once they file. That is the key thing to watch. If those documents actually show detailed plume modeling, emergency response times, and failure scenarios, the public can judge for themselves. If not, the opposition will only get louder.
