Central Illinois opposition mounts against proposed CO2 pipeline

(The Center Square) – Opposition is mounting among farmers and other
residents in central Illinois who are concerned about the Texas
corporation Navigator’s proposal to build a 1,300-mile steel pipeline to
transport highly pressurized, compressed CO2 across their counties.
The pipeline would be 20 inches wide and be buried five feet
underground.
Karen Brockelsby is a farmer in Christian County and is treasurer of
Citizens Against the Heartland Greenway Pipeline. Since representatives
of Navigator knocked on her door a year ago, Brockelsby has done
considerable research on the pipeline proposal.
“This technology has never been done on such a scale, covering such a
distance and involving so many different manufacturing plants,” she told
The Center Square.
Most people think of carbon dioxide as the harmless bubbles in soda or
carbonated water, she said. The highly pressurized, condensed CO2 that
the pipeline is designed to transport is a dangerous liquid that can be
lethal for humans and livestock and dangerous for local waterways,
Brockelsby said.
“In order to transport carbon dioxide, the pipeline operators have to
compress it into a liquid called ‘super critical CO2’. That requires
between 1,400 and 2,200 pounds per square inch of pressure,” Brockelsby
said.
Maintaining that pressure along a 1,300-mile pipeline when there are 30
different fertilizer and ethanol plants along the way that are feeding
it, is a challenge that has never been undertaken before, she said.
A sudden change of pressure in the pipeline can lead to a rupture called
a running ductile fracture, Brockelsby worried.
“The pipe just unzips and a plume of CO2 in a gas form is released. It
will hang near the ground until it is dissipated by wind,” Brockelsby
explained.

People caught in the plume are at risk of suffocation, she said, because
the plume displaces oxygen in the area.
The CO2 liquid is incredibly cold – 109 degrees below zero – similar to
the temperature of the foam in a fire extinguisher. The gas has the
potential to spread over a mile.
In 2020, there was a rupture in a CO2 pipeline in Satartia, Mississippi.
“The cars on the highway quit because gasoline powered engines cannot
not run without oxygen,” Brockelsby said. “People became unconscious.
People had seizures. Fifty people went to the hospital.”
Three hundred residents had to be evacuated from the town.
Exposure on the ground can be fatal to people nearby, Brockelsby said.
Currently there are no federal regulations specifically designed for CO2
pipelines, Brockelsby said. Before the Mississippi accident, regulators
believed that oil and gas pipeline regulations were sufficient for CO2
pipelines.
The Pipeline Hazardous Materials Safety Administration has reviewed the
incident in Mississippi, and they have committed to write new
regulations, addressing issues such as how close a CO2 pipeline can be
to houses, Brockelsby said.
She and other pipeline opponents are asking for a six-month moratorium
on the pipeline permitting process while the regulations are being
developed, she said.
“Right now, there are not even any setbacks as to how close the pipeline
can be to a house,” Brockelsby said.
The CO2 pipeline is proposed to cross a dozen Illinois counties and four
other states. Last July, Navigator Heartland Greenway LLC filed a
petition with the Illinois Commerce Commission seeking permits to build
the pipeline and requesting eminent domain powers. Brokelfey expects the
ICC to take up the issue this year. |
