Which of the following is listed as a federal agency involved in hazmat regulation?

• A. Department of Transportation (DOT)
• B. Department of Energy (DOE)
• C. Environmental Protection Agency (EPA)
• D. Transport Development Group (TDG)

Answer: (D)

The key idea is that hazmat regulation for transportation is led by the Department of Transportation, specifically through the Pipeline and Hazardous Materials Safety Administration. This agency creates and enforces the rules that govern how hazardous materials must be packaged, labeled, documented, and shipped, and it trains those who handle, transport, or load hazmat.

Transport Development Group isn’t a real federal agency, so it doesn’t regulate hazmat. The Environmental Protection Agency does have important hazmat-related roles in environmental protection and hazardous waste programs, and the Department of Energy handles safety for energy and nuclear materials, but for regular hazmat transportation regulations the primary federal regulator is the Department of Transportation.
