Gas Pipelines Get a Rust Break: Inspections Stretch to 5 Years

## Summary

PHMSA wants to change the rules for checking gas pipelines for rust. Instead of inspecting every 3 years after fixing or replacing parts, companies can wait 5 years. This means gas companies save money and still keep pipelines safe.

## Abstract

PHMSA is proposing to revise the corrosion requirements in 49 CFR part 192 for gas distribution systems by replacing the 3-year reassessment interval with a 5-year reassessment interval following the replacement of pipeline segments or components in service lines. This change would provide cost savings to gas distribution operators.

## Effects PRIA read

- Pipeline Reassessment Interval Extended: benefit, medium. PHMSA proposes changing corrosion reassessments after replacing pipeline segments or service-line components from every 3 years to every 5 years. The agency says this change would provide cost savings to gas distribution operators.
