Which entity oversees the transportation of hazardous materials?

The transportation of hazardous materials is overseen by the Department of Transportation (DOT). This agency is responsible for ensuring the safe transport of goods that may pose a risk to public safety and the environment. DOT establishes regulations and guidelines for the handling, packaging, labeling, and transportation of hazardous materials across highways, railways, waterways, and through air transport.

The DOT's Pipeline and Hazardous Materials Safety Administration (PHMSA) specifically focuses on the safe and secure movement of hazardous materials and ensures compliance with federal regulations that govern their transport. Through rigorous standards and enforcement actions, the DOT aims to minimize the risks associated with transporting these materials, thus protecting public health and safety.

Other entities mentioned play important roles in safety and environmental protection but do not directly oversee the transportation of hazardous materials. For example, the Environmental Protection Agency (EPA) deals with environmental regulations and pollutant management, while the Occupational Safety and Health Administration (OSHA) focuses on workplace safety. The Department of Homeland Security (DHS) is more concerned with national security and managing responses to disasters rather than regulating the transport of hazardous materials.
