Notice
Summary
Enable Mississippi River Transmission is planning a new natural gas pipeline to fuel Ameren Missouri’s Big Hollow Energy Center, replacing an old coal plant. The government will review the project’s environmental impact and expects to finish by July 2026. This means cleaner energy and a clear timeline for approvals that affect local communities in Illinois and Missouri.
Analyzed Economic Effects
3 provisions identified: 1 benefits, 1 costs, 1 mixed.
Environmental Review Schedule Set
The Commission plans to issue an Environmental Assessment (EA) for the Ameren-EMRT Big Hollow Project on April 10, 2026, and other federal agencies have a 90-day deadline to decide by July 9, 2026. This gives a clear timeline for review and final federal authorizations related to the pipeline project.
Local Air, Noise, and Land Concerns
Commenters raised concerns about air emissions, noise, and possible impacts to Illinois Nature Preserve Commission-protected lands near the Project. The Commission says all substantive comments on these issues will be addressed in the EA.
Public Comment Window for EA
The EA will be issued for a 30-day public comment period after it is published (EA issuance planned for April 10, 2026). Interested members of the public and landowners can submit comments during that 30-day period for Commission staff to consider.
