A CO2 pipeline rupture could be deadly.
Are you in the Kill Zone?

A CO2 Pipeline rupture sent 45 people to the hospital and sickened hundreds in rural Satartia, Mississippi.

CO2 Pipeline companies in South Dakota won’t release their plume models. What are they hiding?

Plume models from North Dakota indicate a kill zone of 760’ occurs within one minute after the rupture of a 12”-14” diameter pipe.
CO2 Pipelines in South Dakota can be 24” in diameter.

Plume models are notoriously difficult to create

Wind, weather, terrain, soil type, pipe diameter, etc. all impact the outcome of a rupture and the accuracy of a plume model. But that’s not why we don’t have models for the CO2 pipelines going through South Dakota. We’re told CO2 pipeline companies must keep them hidden for national security reasons and because they hold trade secrets. Why are CO2 pipelines a national security risk if they are completely safe?

Using models from multiple research papers, we have created a map of potential risks from these pipelines. We live here (unlike pipeline company investors and employees), and we all need to know if we are in danger from these pipelines. Scroll to the bottom to see a list of the research papers we used to create these maps. According to the scientists that research CO2 pipelines, there hasn’t been enough research done to know if people in the paths of these pipelines are safe.

The map below attempts to show areas that could be impacted by a rupture. Because research models vary greatly, and the maps that the pipeline companies create also vary greatly, a perfect map is not feasible. This example should only encourage you to do your own research and demand that pipeline companies release their own plume models. Download or scroll to see the map for Minnehaha and Lincoln Counties. More maps coming soon.

The city of Madison, in Lake County, SD, is surrounded by lakes, and unfortunately, a dangerous, 2,200 PSI, 24” CO2 pipeline. Small towns, lake homes and farms are in the path of an unnecessary and risky pipeline.

How can you help?

The South Dakota Public Utilities Commission will begin hearings to permit the 8” Navigator Pipeline. This will set the precedence for the 24” Summit Carbon Solutions pipeline.

July 25 - 27th, 9:00 am Navigator's testimony
July 31st - August 5th Landowner testimony
Location: Casey Tibbs South Dakota Rodeo Center
210 Verendrye Dr., Fort Pierre, SD
