Summit Carbon Solutions is asking the Iowa Utilities Commission to approve changes in the permit the commission granted for construction of a pipeline to capture carbon from ethanol plants. State regulators granted the permit in August of 2024, but stipulated Summit had to get permits to extend the pipeline into South Dakota, then to underground storage in North Dakota. Summit is exploring adjustments to its route and is asking the Iowa Utilities Commission for permit changes that would let construction start, when it has secured access to storage. An attorney for the Sierra Club’s Iowa chapter says Summit is mounting a last-ditch effort because South Dakota said no to the project. Summit is also promising to provide $ 8 Million in grants to emergency response agencies along the pipeline route.
