Proposed carbon dioxide pipeline projects put forth by Summit Carbon Solutions and Navigator Ventures have upcoming scheduled public hearings on their permit applications before the South Dakota Public Utilities Commission (SD PUC) — beginning this week on July 25 for Navigator — and the Iowa Utilities Board (IUB), where Summit’s hearings begin next month on Aug. 22. Find details below for landowners and others who wish to participate directly, and observe the hearings in person or online.

In North Dakota, public hearings on Summit’s proposed pipeline were held by the North Dakota Public Service Commission (ND PSC) March 14 (Bismarck), March 28 (Gwinner), April 11 (Wahpteon), May 9 (Linton) and June 2 (Bismarck). Bold Alliance captured video of the proceedings, which featured impassioned testimony from landowners and thorough questioning of Summit’s reps and experts by landowners’ attorneys.

Across the other states through which the proposed CO2 pipelines would pass, Nebraska has no state authority asserted to govern CO2 pipelines at all. In Minnesota, which does not allow the use of eminent domain for CO2 pipelines, the Minnesota Public Utilities Commission (MN PUC) claimed regulatory authority over the carbon pipelines in 2022. The Commission voted to require the preparation of an Environmental Impact Statement (EIS) for just a portion of the Summit project in MN, but no hearings have been scheduled and Summit has said it does not expect any decision from the MN PUC until late 2024 – mid-2025.

In Illinois, Navigator re-submitted its permit application to the Illinois Commerce Commission (ICC) in February 2023, triggering an 11-month permitting process with a decision mandated by January 2024. The ICC has authority over both the proposed CO2 pipeline, and proposed underground CO2 sequestration pore space, for which the company has to date secured very few easements from landowners. A third proposed carbon dioxide pipeline, from Wolf Carbon Solutions partnered with an ADM ethanol plant in Illinois has stated it will not seek eminent domain authority to seize landowners’ property, but has been vague about its project timeline and when it might file permit applications.

Company reps told MN county officials in late May 2023 Summit aims to file permit applications for a “southern branch” in the second quarter of 2023, and a “central branch” sometime in 2023, with an anticipated state permitting timeline of “12 to 18 months,” or late 2024 – mid-2025.
  • Throughout the permitting process there will be multiple points where a member of the public can get involved. Public meetings and hearings where you can attend and learn more about a project, ask questions of agency or company staff, and make a statement about the project for the record. Open comment periods where you can provide a comment and submit it into the record.

Iowa Utilities Board Summit CO2 Pipeline Evidentiary Hearings: Aug. 22 – ?

  • The IUB will begin the hearing process with testimony of landowners subject to eminent domain and provide a video livestream for the entire hearing, allowing landowners and others who are unable to attend in person to observe the hearing remotely. To further assist landowners, the IUB will create a schedule of dates, by area, for receiving testimony on Exhibit H from landowners (TBD). On the subject of mediation and virtual testimony, the IUB will continue to explore these options in order to determine if there is sufficient interest to move forward. At the evidentiary hearing, the IUB will hear evidence in favor of or opposing the proposed pipeline. Following the hearing, the IUB will consider all information presented, including comments and objections filed in the docket, before issuing a final decision and order. 
  • Dates & Time: Tuesday, Aug. 22, 10 a.m. – 5 p.m. (Ending time is tentative)
