2025 IBR Standards Update Fact Sheet
Objectives
This final rule incorporates by reference more than 35 new or updated voluntary, consensus industry technical standards (updated industry standards) within the PSRs (49 Code of Federal Regulation (CFR) parts 190-199). These revised standards will maintain or improve public safety and environmental protection, prevent regulatory confusion, reduce compliance burdens on stakeholders, and satisfy a mandate in the National Technology Transfer and Advancement Act (NTTAA) of 1995 (15 United States Code (U.S.C.) 272 (note)) directing Federal agencies to, "when practical and consistent with applicable laws, use technical standards developed by voluntary consensus standard bodies instead of government-developed technical standards."
PHMSA incorporates more than 80 industry standards by reference into the PSRs; however, many standards become outdated as new editions are released. By updating these standards, PHMSA ensures better alignment of the PSRs with the latest innovations in operational and management practices, materials, testing, and technological advancements; enhances compliance by avoiding conflicts among different versions of the same industry standards; and facilitates the safety-focused allocation of resources by pipeline operators. PHMSA consequently concludes that each of the updated standards in this final rule will either maintain or enhance the protection of public safety and the environment, including avoidance of greenhouse gas emissions in the form of methane releases from gas pipelines. PHMSA further concludes that each of the final rule's updated standards is technically feasible, reasonable, cost-effective, and practicable because of its respective anticipated commercial, public safety, and environmental benefits; and because the benefits better support PHMSA's safety and environmental priorities compared to alternatives, thereby justifying any associated compliance costs.
