Pipeline Safety: Standards Update—ASTM F1973

EnergyEnvironmentTransportation

Summary

The federal government is updating safety standards for pipelines that carry gas and liquids by adopting new technical specifications from ASTM F1973. This update helps ensure pipelines are built and maintained more safely, reducing the risk of leaks, ruptures, and accidents that could harm communities and the environment.

Key Points

  • 1PHMSA (the Pipeline and Hazardous Materials Safety Administration) is adopting updated ASTM F1973 standards to improve how pipelines are designed, tested, and inspected
  • 2These new standards apply to companies that operate natural gas pipelines, oil pipelines, and other hazardous liquid transportation systems across the country
  • 3The updated standards include stricter requirements for pipe materials, welding quality, pressure testing, and ongoing maintenance to prevent failures
  • 4Pipeline operators will need to comply with these new standards within a specified timeframe, which may require upgrades to existing pipelines or changes to how new ones are built
  • 5The changes aim to protect public safety and reduce environmental risks in communities near pipeline infrastructure

Impact Assessment

If you are an energy company or pipeline operator, this means you must update your pipeline construction and maintenance procedures to comply with new ASTM F1973 technical standards, requiring equipment upgrades and staff retraining.
