Which of the following is a federal regulation related to hazardous materials?

The Resource Conservation and Recovery Act (RCRA) is the correct choice as it is a key federal regulation specifically focused on the management of hazardous waste. This law establishes a framework for the proper handling, treatment, storage, and disposal of hazardous materials to protect human health and the environment. It emphasizes the importance of waste minimization and encourages recycling whenever possible. The law also outlines the processes for identifying hazardous waste and the responsibilities of those who generate and manage it.

While the Clean Water Act, Occupational Safety and Health Act, and Toxic Substances Control Act are also significant federal regulations, they cover different aspects. The Clean Water Act focuses on regulating discharges of pollutants into the waters of the United States, rather than hazardous waste management. The Occupational Safety and Health Act addresses workplace safety and health, aiming to ensure safe working environments, but it does not specifically target hazardous materials in the same way that the RCRA does. The Toxic Substances Control Act regulates the introduction of new or already existing chemicals, concerned primarily with their use rather than their disposal as waste. Thus, RCRA stands out as the primary federal regulation concerning hazardous materials management.
