Under RCRA, the EPA standards must be followed by all persons who do what?

The correct response highlights that the EPA standards under the Resource Conservation and Recovery Act (RCRA) must be adhered to by all individuals or entities involved in generating, transporting, treating, storing, or disposing of hazardous waste. This comprehensive scope is essential because RCRA was established to manage hazardous waste from its creation to its final disposal, ensuring that all aspects of hazardous waste handling are regulated to protect human health and the environment.

When individuals generate hazardous waste, they have a responsibility to manage it properly, which includes following regulations for its safe transport, treatment, storage, and disposal. By including all five activities in the correct answer, it's acknowledged that the waste management process is interconnected, requiring strict adherence to EPA standards at every stage. This comprehensive framework is necessary to minimize the risks associated with hazardous waste, such as environmental contamination and health hazards.

Other options may not encompass all the required responsibilities under RCRA, which can lead to gaps in compliance and potentially jeopardize health and environmental safety.
