[Docket No. PHMSA-2019-0091]
In an advance notice of proposed rulemaking (ANPRM) published May 5, 2025, PHMSA is asking for stakeholder feedback on updating its liquefied natural gas (LNG) facility rules in 49 CFR Part 193. Comments are due by July 7, 2025. The agency hasn’t overhauled these siting, design, construction, inspection, testing, operation, and maintenance requirements in more than 20 years and will use this input to shape a formal notice of proposed rulemaking (NPRM).
This effort responds to how the U.S. LNG industry has grown into a global, technologically advanced sector and to repeated calls from Congress, the Government Accountability Office, and industry groups to modernize safety standards. Laws like the PIPES Act of 2016 and PIPES Act of 2020 specifically directed PHMSA to strengthen minimum safety rules for permanent, small‑scale LNG facilities, highlighting the need for an updated regulatory framework.
