CO₂ Pipelines

Senate Bill 614 requires Office of the State Fire Marshal (OSFM) to adopt regulations governing the safe transportation of carbon dioxide in pipelines that are, at a minimum, as protective as the draft federal regulations set forth in the unofficial version of the Notice of Proposed Rulemaking issued by the PHMSA on January 10, 2025.

OSFM is working with stakeholders to develop CO2 pipeline regulations that will cover pipeline design and material requirements, valve studies and spacing, leak detection and warning systems, construction, testing, and emergency planning training, and response. The workgroup includes representatives from industry, nonprofit pipeline safety organizations, environmental groups, state agencies, and city/county agencies.
