PHMSA ADB-2020-02 Overpressure Protection on Low-Pressure Natural Gas Distribution System

[Docket No. PHMSA-2020-0025]

PHMSA issued an advisory bulletin to remind owners and operators of natural gas distribution pipelines of the possibility of failure due to an over-pressurization on low-pressure distribution systems. PHMSA also reminds pipeline operators of their obligations to comply with the gas DIMP regulations at 49 CFR Part 192, Subpart P. 

PHMSA encourages operators to review the NTSB’s Pipeline Accident Report concerning Columbia Gas of Massachusetts’ over-pressurization event in the Merrimack Valley on September 13, 2018. It may be instructive regarding a host of potential safety problems that operators of low-pressure natural gas distribution systems may need to address. A copy of NTSB’s accident report is contained within Docket No. PHMSA–2020–0025 for this advisory bulletin.
