Pipeline Safety: Standards for Increasing the Maximum Allowable Operating Pressure for Gas Transmission Pipelines

Final rule.
PHMSA is amending the pipeline safety regulations to prescribe safety requirements for the operation of certain gas transmission pipelines at pressures based on higher operating stress levels. The result is an increase of maximum allowable operating pressure (MAOP) over that currently allowed in the regulations. Improvements in pipeline technology assessment methodology, maintenance practices, and management processes over the past twenty-five years have significantly reduced the risk of failure in pipelines and necessitate updating the standards that govern the MAOP. This rule will generate significant public benefits by reducing the number and consequences of potential incidents and boosting the potential capacity and efficiency of pipeline infrastructure, while promoting rigorous life-cycle maintenance and investment in improved pipe technology.
