Who is the primary regulatory agency for hazardous materials transport in the United States?

The primary regulatory agency for hazardous materials transport in the United States is the Federal Motor Carrier Safety Administration (FMCSA). This agency is responsible for regulating the transportation of hazardous materials via commercial vehicles on public roads. FMCSA establishes and enforces safety regulations that govern the transportation of these materials, ensuring that carriers follow guidelines for safe handling, packaging, labeling, and documentation.

While other agencies like the Environmental Protection Agency (EPA) are crucial in regulating hazardous waste management and environmental effects, their focus is not specifically on the transport of hazardous materials. The Federal Aviation Administration (FAA) predominantly oversees air travel and safety in aviation, which does include certain guidelines for hazardous materials transported by air, but it does not encompass all modes of transport. Similarly, the Occupational Safety and Health Administration (OSHA) ensures safety and health regulations in the workplace but does not regulate transportation logistics. Each agency has its designated areas of responsibility, but for hazardous materials transport specifically by road, FMCSA is the leading authority.
