Pipeline Safety: Design and Construction Standards To Reduce Internal Corrosion in Gas Transmission Pipelines

Summary: This final rule requires operators to use design and construction features in new and replaced gas transmission pipelines to reduce the risk of internal corrosion. 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.
