Pipeline Safety Alert
(by James Curry, Keith Coyle and Brianne Kurdock)
On February 6, 2020, the Pipeline and Hazardous Materials Safety Administration (PHMSA) published a notice of proposed rulemaking (NPRM) in the Federal Register containing new valve installation and minimum rupture detection standards for gas and hazardous liquid pipelines. The NPRM would require the installation of automatic shutoff valves (ASV), remote-control valves (RCV), or equivalent technology, on certain gas transmission and hazardous liquid pipelines. The NPRM also contains proposed requirements for rupture detection and mitigation, including provisions for improving emergency response and conducting failure investigations and analyses. Public comments must be filed in response to the NPRM on or before April 6, 2020. Additional background information and a brief summary of PHMSA’s proposals are provided below.
Why Did PHMSA Issue the NPRM?
In 2010, a pair of significant pipeline incidents occurred in Marshall, Michigan, and San Bruno, California. The resulting NTSB investigations led to the issuance of safety recommendations relating to the use of ASVs and RCVs and other measures to improve rupture detection and response. Also, in the Pipeline Safety, Regulatory Certainty, and Job Creation Act of 2011 (2011 Act), Congress added mandates to the Pipeline Safety Act directing PHMSA to conduct studies and, if appropriate, establish regulations to address the concerns identified in NTSB’s safety recommendations. In the years following the 2011 Act, PHMSA commissioned the studies required by the congressional mandates and received separate recommendations from GAO on the need to improve pipeline incident response. PHMSA also issued two ANPRMs after the 2010 pipeline incidents asking for public comment on the need to amend the pipeline safety regulations for valve installation and rupture detection. …
