Pipeline Safety Alert – PHMSA Publishes Long-Awaited Mega-Rule for Gas Transmission Lines

On October 1, 2019, the Pipeline and Hazardous Materials Safety Administration (PHMSA or the Agency) published a final rule in the Federal Register amending the federal safety standards for gas pipeline facilities at 49 C.F.R. Part 192 (Rule). The Rule primarily addresses concerns identified in congressional mandates and National Transportation Safety Board (NTSB) recommendations for gas transmission lines.  The most significant provisions include new requirements for verifying pipeline materials, reconfirming maximum allowable operating pressure (MAOP), and performing periodic assessments of pipeline segments located outside of high consequence areas (HCAs), including in newly-defined moderate consequence areas (MCAs).  Other changes include amendments to the integrity management (IM) requirements, new requirements for reporting MAOP exceedances and the safety of inline inspection launcher and receivers, as well as related recordkeeping requirements.

This alert is the first in a four-part Babst Calland series on the Rule.  This first alert discusses the new MAOP reconfirmation and material verification requirements.  The next alert will cover MCAs and new assessment requirements for pipelines located outside of HCAs.  The third client alert will review the new recordkeeping requirements.  Finally, Babst Calland will survey the remaining Rule topics.
