Experts: Predicting CO2 pipeline rupture threats can be extremely costly

BY: - June 1, 2023

DES MOINES, Iowa — A carbon dioxide plume modeling software did not anticipate the threat a pipeline break in 2020 posed to a small Mississippi town, largely because it did not take land topography into account. That break near Satartia, Mississippi, resulted in emergency responders scrambling to save people from a “green gas” and “rotten […]

Feds: Carbon dioxide pipelines are necessary to reduce emissions

BY: - May 31, 2023

Up to 60,000 miles of carbon dioxide pipeline must be installed in the United States to help eliminate the greenhouse gas emissions by 2050, according to a federal engineer. Part of that mileage might come from proposed pipelines that would cross Iowa and transport captured carbon dioxide from ethanol plants for underground sequestration or other […]

Environmental groups seek Biden moratorium on carbon dioxide pipelines

BY: - May 25, 2023

President Joe Biden should prevent the construction of new carbon dioxide pipelines until changes to federal rules are adopted to increase their safety, opponents of the projects said Thursday. The call for an executive order to stall the projects comes as federal regulators consider changes to pipeline requirements and are set to hold a two-day […]

Tie vote delays decision on carbon pipeline policy in Minnehaha County

SIOUX FALLS — Minnehaha County commissioners gridlocked Tuesday on setbacks from rural homes and postponed a vote on an ordinance with the potential to scuttle two carbon capture pipelines. The absence of Commission Chair Jean Bender set the stage for a 2-2 vote and a return to the issue at the June 6 meeting. Plenty […]

Landowner battles against pipelines vary by state

Sprawling Midwestern pipelines that would carry captured carbon dioxide from ethanol plants and other facilities would change little when they cross state lines. The proposals would be constructed the same way in Iowa, Illinois, Minnesota, Nebraska and the Dakotas — with carbon steel pipe ranging from 4 to 24 inches in diameter with operating pressures […]

Judge says Iowa’s pipeline land survey law is constitutional

BY: - May 12, 2023

An Iowa district court judge decided this week that a state law is constitutional that allows land surveys for carbon dioxide pipelines regardless of landowners’ consent, according to court records. The ruling — in a Hardin County case — is at odds with another judge’s ruling last week in Clay County, which said the law does not […]

County commissioner: Carbon pipelines should outfit volunteer fire departments

BY: - March 30, 2023

A Minnehaha County commissioner wants volunteer firefighters in the state’s most populous county to ask for safety equipment from two carbon pipeline companies for use in the event of a pipeline failure — something the companies say they’re willing to do. The suggestion from Commissioner Joe Kippley came last week on the heels of a […]
