US proposes brand-new guidelines for carbon dioxide pipeline safety

A U.S. regulator on Wednesday proposed new rules to enhance security requirements for carbon dioxide and hazardous liquid pipelines at a time when carbon capture technologies see increased adoption to eliminate international warming.

The new guidelines will reinforce existing requirements and, for the first time, establish brand-new norms for transferring carbon dioxide in a gaseous state via pipeline, the U.S. Department of Transportation's Pipeline and Hazardous Products Safety Administration (PHMSA) stated.

The U.S. has actually anticipated a boost in carbon dioxide pipelines across the nation as the battle versus worldwide warming leads to higher adoption of carbon capture and sequestration innovations.

Among the rules needs more in-depth vapor dispersion analyses to much better secure the public and the environment in case of a pipeline failure.

I have learned firsthand from impacted communities in Mississippi and across America why we require more powerful CO2 (carbon. dioxide) pipeline security requirements, PHMSA Deputy Administrator. Tristan Brown said.

In 2020, Denbury's 24-inch Delta Pipeline burst in. Satartia, Mississippi, launching countless barrels of CO2,. which resulted in regional evacuations and caused 45 individuals to be. hospitalized.

Liquid CO2 vaporizes when released to the environment, and. the vapor is 1.53 times heavier than air. It displaces oxygen,. potentially asphyxiating humans and animals, according to PHMSA.

In 2023, Denbury and PHMSA decided on a penalty of about. $ 2.8 million, almost $1 million less than the initial proposition. in 2022.
