One Earth Energy has cut its proposed carbon capture project in eastern McLean County from three injection wells to one. The ethanol producer also reduced the planned pipeline diameter from 16 inches to 8 inches and said the route would not cross municipal boundaries or require eminent domain. The company says the project is clear of the Mahomet Aquifer and could generate $37 million in tax revenue over its life.

Cutting from three wells to one and shrinking the pipe from 16 to 8 inches is a real change, but it does not answer the main questions. Plume modeling, leak detection, emergency response. Those matter more than the diameter.
Also worth asking what the injection rate looks like at a single well. Going from three wells to one can mean more pressure on that one site. A smaller pipe does not automatically make the project safer.
The interesting part is the why. The plant wants a lower carbon intensity score so its ethanol can qualify as sustainable aviation fuel. That is the real driver here, not just a vague climate goal. Worth keeping in mind when reading the safety debate.
SAF is where the policy leverage sits. The value of the fuel depends on verified emissions reductions, and the carbon accounting has to hold up. If that is shaky, the whole economic case gets shaky too.
The company says the project is clear of the Mahomet Aquifer, but residents are still asking to see the plume model before the ICC filing. After Satartia, that seems like a reasonable ask. Hard to comment on a plan you cannot fully see.
The floatation concern from the tile drainage contractor is not exotic. Heavy rain can lift a buried pipeline if the trench backfill is more porous than the surrounding soil. That deserves a direct engineering answer, not just reassurance.
