Pipeline Accountability Act of 2025

Strengthens federal pipeline safety rules, adds climate and low-emission considerations to standards, requires studies and new rulemaking for hydrogen blending, CO2 pipelines, and underground natural gas storage, and creates a new Office of Public Engagement to improve public information and community support after incidents. It imposes new operator duties (including isolation after ruptures and public disclosure of emergency/safety information), tightens incident and product-reporting rules, limits conflicts of interest on standards committees, expands civil enforcement and litigation venues, and authorizes funding for safety grants, modernization, and the new office.
