PHMSA seeks comments about regulating carbon dioxide pipelines

The US Pipeline & Hazardous Materials Safety Administration is seeking comments on a report it developed, “Background for Regulating the Transportation of Carbon Dioxide in a Gaseous State,” as part of its effort to develop minimum requirements for safely transporting CO2, the US Department of Transportation agency announced.

The report evaluates present and potential future CO2 gaseous pipelines and outlines PHMSA’s approach for establishing regulations, it said in a June 27 Federal Register notice. The agency is seeking to better understand where CO2 pipelines, which it does not regulate currently, are located so it can establish requirements as mandated under the 2011 Pipeline Safety Reauthorization Act. Comments will be accepted through July 27.

After carefully reviewing the available information with regard to gaseous carbon dioxide pipelines, PHMSA has been unable to identify specific gaseous CO2 pipelines or pipeline operators which would potentially be subject to future regulation under Section 15 of the 2011 law, the agency said.

It said it is seeking comments to better understand the possible effects of the regulatory scenarios presented within the report, information considered within the report, conclusions that could be drawn from the report, information missing from the report, and to better understand the locations and extent of existing or planned gaseous CO2 pipelines.
