On March 17, the U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety Administration (PHMSA) proposed new regulations to update critical safety requirements for natural gas pipelines. The prior legislation, the Pipeline Safety, Regulatory Certainty, and Job Creation Act of 2011, expired at the end of FY 2015 but called for PHMSA to evaluate the need for additional damage prevention and inspection regulations.
The 549-page, pre-publication edition of the proposed regulations for gas transmission and gathering lines took over four years to make and includes four congressional mandates, one recommendation from GAO, and six recommendations from the National Transportation Safety Board (NTSB).
PHMSA’s new proposals include a climate action plan to reduce methane emissions and inspections for previously exempt gas pipelines built before 1970, such as the PG&E pipeline that exploded and started fires in San Bruno, CA in 2010, killing eight people and leveling 35 houses, and the pipeline explosion in 2011 in Allentown, Pa., which killed five people including a 4-month-old child. Both explosions were caused by leaks from old cast-iron natural gas distribution pipelines. NTSB’s investigation of the PG&E natural gas pipeline failure concluded that hydrostatic testing of grandfathered pipelines would have likely have prevented the explosion.
The proposed regulations would also broaden the scope of safety coverage by adding new assessment and repair criteria for gas transmission pipelines, including pipelines that pass through areas of medium population density where a failure could pose a serious risk to residents.
The significant growth in the nation’s production, usage and commercialization of natural gas is placing unprecedented demands on the nation’s pipeline system,” said U.S. Transportation Secretary Anthony Foxx.
“This proposal includes a number of commonsense measures that will better ensure the safety of communities living alongside pipeline infrastructure and protect our environment.”
