Pipeline Safety: Standards Update—ASTM A381/A381M

EnergyEnvironmentTransportation

Summary

This federal rule updates safety standards for pipelines that transport oil and gas by adopting the latest ASTM A381/A381M material specifications. The update ensures pipelines are built and maintained with stronger, more reliable materials to reduce the risk of leaks, ruptures, and accidents that could harm communities and the environment.

Key Points

  • 1Updates the material standards that pipeline companies must follow when building or repairing pipelines that carry oil and natural gas
  • 2Requires pipelines to use materials that meet the newer ASTM A381/A381M specifications, which have improved safety and durability features
  • 3Applies to pipeline operators and manufacturers who must ensure their equipment meets these updated standards
  • 4Aims to prevent pipeline failures that could cause spills, explosions, or damage to nearby homes and neighborhoods
  • 5Pipeline companies will need to update their equipment and inspection procedures to comply with the new material requirements

Impact Assessment

If you are an energy company operating oil and gas pipelines, this means you must upgrade to stronger materials meeting ASTM A381/A381M standards, requiring capital investment in new equipment and potential system modifications.
