Which agency is responsible for regulating the movement of hazardous chemicals?

The U.S. Department of Transportation (DOT) is responsible for regulating the movement of hazardous chemicals. This agency oversees the safe and effective transportation of hazardous materials across the country, ensuring compliance with federal regulations designed to protect public safety and the environment. The DOT establishes guidelines and standards for the packaging, labeling, and transporting of hazardous materials, and it plays a critical role in coordinating with other agencies to manage hazardous materials incidents, ensuring the safety of transport by road, rail, air, and waterways.

The other options do not specifically regulate hazardous materials transportation. The Federal Bureau of Investigation focuses primarily on national security and crime prevention, the Interstate Commerce Commission historically dealt with interstate commerce regulations but has been defunct since 1995, and the Department of Health and Human Services is more concerned with public health and welfare rather than transportation logistics. Therefore, the correct answer highlights the DOT’s essential role in this area.
