Report Recommends Revisiting Federal Safety Regulations for Liquid Petroleum Gas Distribution Systems

Current federal safety regulations for small distribution systems used for propane and other liquefied petroleum gases (LPGs) should be improved for clarity, efficiency, enforceability, and applicability to risk, says a new report from the National Academies of Sciences, Engineering, and Medicine. Because compliance with the federal regulations is not enforced consistently by states, there is little understanding of how the requirements affect the safety of the gas pipeline systems, particularly the smallest ones with fewer than 100 customers.
While most LPG systems consist of a storage tank and supply lines that serve a single home or business, some systems are configured to deliver LPG to multiple homes or businesses. When these multi-user systems serve 10 or more customers, or if they have two or more customers and part of the system is located in a public place, they become subject to federal safety regulations administered by the Pipeline and Hazardous Materials Safety Administration (PHMSA) of the U.S. Department of Transportation. The federal regulations, which are LPG-specific and apply to all LPG systems regardless of the number of customers, supplement the safety standards of the National Fire Protection Association (NFPA). In most cases, states enforce the federal regulations as well their own regulations and the NFPA codes…(Read the full story)
