By Robin OpsahlThe Iowa chapter of the Sierra Club and some landowners called Tuesday for the Iowa Utilities Commission to reject Summit Carbon Solutions’ petition to amend its pipeline permit. The petition, filed Monday, requests changes to the initially proposed route and pipe size for the carbon sequestration pipeline project, which had been approved by the IUC in 2024. That approval came with requirements that Summit could not begin construction until it received route permission from North Dakota and South Dakota, and storage permission in North Dakota. Since the IUC’s initial approval, South Dakota has enacted a law preventing the use of eminent domain in CO2 pipeline projects, and has denied two of Summit’s permit requests. “As we noted when South Dakota changed their law, there are many places to sequester carbon and there are many ways to get to those locations that do not involve South Dakota,” Shaw said.
