The Hazardous Materials Transportation Act (HMTA) specifically regulates hazardous materials that are transported across state lines, making this the correct option. The act is designed to ensure that hazardous materials are transported safely, minimizing risks to public health and the environment. This includes setting standards for handling, packaging, and labeling these materials during transport.

The emphasis on interstate transportation highlights the importance of regulating hazardous materials as they move between different jurisdictions, which may have varying regulations. Therefore, compliance ensures uniform safety measures across state lines, protecting both the workforce involved in transportation and the communities through which these materials pass.

In contrast, non-hazardous waste, large quantity waste, and general waste from industrial sources do not fall under the specific provisions of the HMTA in the same way. Non-hazardous waste is generally managed under different regulations, large quantity waste is more relevant to other regulatory frameworks like the Resource Conservation and Recovery Act (RCRA), and general industrial waste does not inherently refer to the specific regulations of hazardous materials during transit as outlined by the HMTA.
