PHMSA Issues Final Rule on Design and Construction Standards to Reduce Internal Corrosion in Gas Transmission Pipelines

The DOT/PHMSA has issued a final rule requiring operators to use design and construction features in new and replaced gas transmission pipelines to reduce the risk of internal corrosion. The rulemaking proceeding was initiated in response to a 2003 recommendation of the National Transportation Safety Board (NTSB) and corresponding advice of the Technical Pipeline Safety Standards Committee (TPSSC). This final rule takes effect May 23, 2007.

The design and construction features required by this rule will reduce the risk of internal corrosion and related pipeline failures by reducing the potential for accumulation of liquids and facilitating operation and maintenance practices that address internal corrosion. The basic requirements of this final rule are similar to those proposed in the NPRM:

  • New and replaced gas transmission pipelines must be configured to reduce the risk that liquids will collect in the line
  • Have effective liquid removal features
  • Allow use of corrosion monitoring devices in locations with significant potential for internal corrosion

The final rule adds new subsections to § 192.143 in Subpart D-Design of Pipeline Components and to § 192.476 which requires an operator to address internal corrosion risk when designing and constructing a new gas transmission line or when replacing line pipe or components in a transmission line.
