The Pipeline and Hazardous Materials Safety Administration (PHMSA) is a United States Department of Transportation agency created in 2004, responsible for developing and enforcing regulations for the safe, reliable, and environmentally sound transportation of energy and other hazardous materials. The agency is in charge of overseeing roughly 3.4 million miles of pipelines, accounting for 65% of the energy consumed in the U.S., and regulating the nearly one million daily shipments of hazardous materials by land, sea, and air. This includes pipelines carrying carbon dioxide carbon capture and utilization.
