Which agency primarily oversees the regulations governing the transportation of hazardous materials?

The Department of Transportation (DOT) is the agency primarily responsible for overseeing the regulations governing the transportation of hazardous materials. This authority is established under various legislative frameworks, including the Hazardous Materials Transportation Act. The DOT is tasked with ensuring that hazardous materials are transported safely and efficiently, minimizing risks to public health and the environment. It develops guidelines and regulations that govern everything from packaging and labeling to training requirements for personnel involved in the transportation of these materials.

In addition to regulations, the DOT also conducts inspections and provides training resources to ensure compliance among shippers and transporters. Their role is critical in maintaining safety during the transport of potentially dangerous substances, which can include chemicals, biological agents, and other hazardous materials.

Other agencies such as the Environmental Protection Agency (EPA) and the Occupational Safety and Health Administration (OSHA) do have important roles regarding hazardous materials but focus on different aspects. The EPA primarily deals with environmental regulations and hazards posed to ecosystems and human health, while OSHA primarily focuses on workplace safety and health regulations. The Federal Bureau of Investigation (FBI) does not oversee hazardous materials transportation and is more oriented towards criminal investigations and national security. Thus, the DOT is the correct agency for this particular area of concern.
