Notice
Summary
Northern Natural Gas Company wants to build new pipeline facilities in Iowa and Nebraska to deliver more natural gas for homes, businesses, and power plants. The government will review the project's environmental impact and share a report by December 7, 2026, with a final decision expected by March 7, 2027. This means more energy and careful checks to keep things safe and smooth for everyone involved.
Analyzed Economic Effects
2 provisions identified: 1 benefits, 1 costs, 0 mixed.
Adds 535,360 dekatherms/day Capacity
Northern Natural Gas proposes to add 535,360 dekatherms per day of winter peak firm transportation service to serve power plants and residential and commercial customers in its Market Area. This increases the pipeline capacity available for heating, businesses, and electricity generation during winter peak demand.
Local Land and Farming Disruption Risk
The project would construct about 26.2 miles of 20- and 30-inch pipeline plus a new compressor station, modifications at five compressor stations, uprates, and a new meter facility in counties in Iowa and Nebraska. Potentially affected landowners raised impacts on groundwater, farming and grazing, recreation, land value, future development plans, and access to wildlife; the Commission will address substantive comments in the Environmental Assessment.
