Safety Regulation for Small LPG Distribution Systems
Most of the more than 12 million households and businesses that use LPG are on single-customer systems but a small number—between 3,800 and 5,800—are served by multi-user systems. These systems are potentially subject to federal safety regulations administered by the U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety Administration (PHMSA).

, Protecting Our Infrastructure of Pipelines and Enhancing Safety Act of 2016, this new report from the National Academies of Sciences, Engineering, and Medicine examines the regulatory framework for gas pipeline systems that transport propane and other types of liquefied petroleum gas (LPG) for service to 100 or fewer customers, reviews what is known about their safety performance, and provides recommendations on ways to make their regulatory requirements more risk-based.
