 The Iowa Utilities Board granted approval for a proposed carbon pipeline project to begin in the state. That clears the way for Summit Carbon to build the segment of the pipeline that covers 688 miles in 29 Iowa counties. The board hasn't yet granted a permit that would allow construction to begin. However, Summit can now use eminent domain to acquire the land they need to complete the project. The board issued a final 507-page decision and order. Summit will be required to submit numerous revised exhibits before the board issues a permit and before construction begins.
