SIOUX FALLS, S.D.(KELO)- Senator Mike Rounds says CO2 pipeline companies have given themselves a black eye…but he believes they’ll prevail.

Navigator Heartland and Summit Carbon Solutions both want to build carbon capture pipelines in several states, including South Dakota.

Navigator wants the Public Utilities Commission to overturn pipeline zoning regulations in Minnehaha and Moody counties.

At the same time, pipeline opponent Ed Fischbach says right now the pipeline companies can’t get into the states that are supposed to receive the CO2 they want to deliver.

The PUC expects to make its decision on Navigator’s application in early September.
