What must all CNG cargo tanks comply with?

All CNG cargo tanks must comply with the US DOT Code of Federal Regulations or Transport Canada TDG because these regulations set the standards for the safe transport of hazardous materials, including compressed natural gas. The Code of Federal Regulations outlines specific design, construction, testing, and maintenance requirements for cargo tanks, ensuring they can safely contain CNG under pressure and minimize the risk of leaks or failures during transport. Complying with these federal regulations is vital for the safety of the drivers, vehicles, and the public, as well as for the environmental protection of the areas through which CNG is transported.

While local county regulations, classified hazardous material regulations, and state environmental codes may also be important, they often operate within the framework established by federal guidelines. This means that compliance with the federal regulations is usually a baseline requirement that local or state regulations may build upon.
