The Pipeline and Hazardous Materials Safety Administration, or PHMSA, announced Wednesday a notice of proposed rule making to strengthen guidelines for carbon dioxide pipelines. The proposed rule would apply to carbon dioxide transported in a supercritical liquid state through pipelines and establishes,

A federal agency regulating CO2 pipelines is proposing new changes following a four-year investigation of a CO2 pipeline leak in Mississippi and the new mandates would affect pipelines in South Dakota,

The DOT this week proposed a new set of safety requirements for the operators of CO2 and hazardous liquid pipelines.

On January 15, 2025, the Pipeline and Hazardous Materials Safety Administration (PHMSA) of the U.S. Department of Transportation released a pre-publication version of a notice of proposed rulemaking (NPRM) that would propose new safety regulations for pipelines that transport carbon dioxide (CO2).

With carbon capture pipelines proliferating, U.S. regulators propose stricter rules to prevent a leak like on in Satartia, Mississippi, in 2020

The new regulations will strengthen existing standards and, for the first time, establish new norms for transporting carbon dioxide in a gaseous state via pipeline, the U.S. Department of Transportation's Pipeline and Hazardous Materials Safety Administration (PHMSA) said.
