Abstract
This DFR amends PHMSA's regulations to incorporate by reference an updated edition of industry standard ASTM A333/A333M, Standard Specification for Seamless and Welded Steel Pipe for Low- Temperature Service and Other Applications with Required Notch Toughness. This updated standard will maintain or improve public safety, prevent regulatory confusion, reduce compliance burdens on stakeholders, and satisfy a mandate in the National Technology Transfer and Advancement Act (NTTAA) of 1995.
