EnergyTransportationEnvironment

Summary

The federal government is updating safety standards for pipelines that transport hazardous liquids and natural gas by adopting new industry guidelines. These updates aim to prevent pipeline accidents, leaks, and explosions that could harm communities and the environment.

Key Points

  • 1Updates pipeline safety standards by incorporating new American Petroleum Institute (API) technical guidelines (RP 1170 and RP 1171) into federal requirements
  • 2Applies to companies that operate pipelines carrying oil, natural gas, and other hazardous liquids across the country
  • 3Addresses safety issues like corrosion prevention, maintenance procedures, and emergency response plans to reduce the risk of pipeline failures
  • 4Requires pipeline operators to implement these new standards within a specified timeframe or face penalties from the Pipeline and Hazardous Materials Safety Administration (PHMSA)
  • 5Protects communities near pipelines by establishing stronger safety practices and reducing the potential for accidents that could cause injuries, environmental damage, or property loss

Impact Assessment

If you are an energy company operating hazardous liquid or natural gas pipelines, this means you must upgrade your pipeline systems and safety procedures to meet new federal standards, requiring capital investment and operational changes.
