Do you have something to say about Pipeline Safety?!

Pipeline Safety: Gaseous Carbon Dioxide Pipelines

PHMSA has released a report titled “Background for Regulating the Transportation of Carbon Dioxide in a Gaseous State,” and is seeking comments from you! This is all part of PHMSA’s effort to develop minimum requirements for safely transporting CO2.

Since PHMSA’s ability to reach out and locate potentially affected operators has been limited, as it does not currently regulate these pipelines, it is welcoming views and updates on the necessity for and approach to regulations for gaseous carbon dioxide pipelines per section 15 of the Act. Some areas of interest include:

  1. Comments and suggestions with respect to the information included within the report, including comments on gaseous carbon dioxide pipelines and their regulation in general, as well as any conclusions readers can draw from the information presented.
  1. Identifying gaseous carbon dioxide pipelines or pipeline operators not already identified in the report that would potentially be subject to regulation if they are regulated as outlined in the report per the requirements of section 15 of the Act. Include details, if available, such as pipeline location and length.
  1. Identifying and discussing likely locations for the future construction of gaseous carbon dioxide pipelines not already discussed in the report that would potentially be subject to regulation if regulated as outlined in the report per the requirements of section 15 of the Act.
  1. Comments on the two potential options for regulating gaseous carbon dioxide outlined in the report. These options would:
  • Regulate the transport of gaseous CO2 entirely under part 192, or
  • Regulate the transport under part 192, where appropriate, with reference to applicable sections of part 195.
    PHMSA would like to know which approach you think is more appropriate or preferable, if neither approach would be, or if both would be considered appropriate. They ask that when commenting, you provide supporting examples and reasons for your opinion.

  1. Please discuss the industry projections for carbon dioxide pipeline need and growth as identified in the report, and whether these projections are consistent and accurate with current data. If they have changed, please discuss how they have changed.
  1. Please comment on any technical standards addressing gaseous carbon dioxide pipelines that PHMSA could consider incorporating into any potential regulations.
  1. If PHMSA pursues one of the regulatory scenarios presented within the report, and as stated in Area #4 above, would a simpler approach be adequate and responsible at this time? Could PHMSA make a change to the scope of part 192 to include gaseous carbon dioxide without any further technical differentiations within the regulations or without referencing the regulations for carbon dioxide in the supercritical state per existing part 195 regulations?

You can go to the Federal Register to submit any comments or the Regulations.gov site. There you can also view the full report. Comments submitted will be posted without edits to http://www.regulations.gov/, including any personal information provided. You can also Kenneth Lee, Director, Engineering and Research Division, at 202-366-2694 or Kenneth.lee@dot.gov.
