Which federal agency is responsible for regulating the transportation of LP gas?

The Pipeline and Hazardous Materials Safety Administration (PHMSA) is the federal agency tasked with regulating the transportation of various hazardous materials, including liquefied petroleum (LP) gas. This agency develops and enforces regulations that ensure the safe and secure transportation of hazardous materials by various modes, such as pipelines, rail, air, and highways. Specifically, PHMSA's role includes setting standards for the safe containment, marking, and handling of LP gas during transport to prevent accidents and environmental hazards.

In contrast, other agencies mentioned have different focuses. The Environmental Protection Agency (EPA) primarily deals with environmental protection regulations, focusing on pollution control and the management of natural resources rather than transportation safety. The Occupational Safety and Health Administration (OSHA) oversees workplace safety and health standards but does not directly regulate transportation issues. The Federal Aviation Administration (FAA) is responsible for regulating civil aviation and does not oversee the transportation of hazardous materials outside of air travel. This distinction underlines why PHMSA is specifically responsible for LP gas transportation regulation.
