# PHMSA Proposes Modern LNG Safety Rules

The Pipeline and Hazardous Materials Safety Administration (PHMSA) published a Notice of Proposed Rulemaking to update U.S. safety regulations for liquefied natural gas facilities. The proposal would incorporate NFPA Standard 59A (2026 edition) and allow technologies including pipe-in-pipe systems, single-walled ASME containers, and membrane storage tanks. PHMSA estimates the changes could generate $100 million in annual savings while supporting LNG infrastructure development.

- LNG facility operators and contractors should review how the proposed standards and technology provisions could affect facility design, construction, and safety practices.
- Engineering, equipment, and infrastructure firms may find opportunities as the proposed changes accommodate newer LNG storage and piping technologies.
- The proposal is a rulemaking, not a contract award; affected organizations can provide input during the rulemaking process. The signal specifies no submission deadline.
