Pesticide applicators generate waste during normal work operations. Which of the items below is not "regulated waste" under the Federal Resource Conservation and Recovery Act (RCRA)?

Triple-rinsed used containers are not categorized as "regulated waste" under the Federal Resource Conservation and Recovery Act (RCRA). This is because, when containers are triple-rinsed properly, they have effectively been cleaned of any remaining pesticide residues, which allows them to be considered non-hazardous. Because they no longer exhibit the characteristics of hazardous waste, they can often be recycled or disposed of without being subject to the stringent regulations that govern hazardous waste.

In contrast, excess pesticide and pesticide dilutions, as well as rinsewater that contains listed chemicals, are considered regulated because they can still pose environmental hazards or risks to human health and are likely to contain constituents that qualify them as hazardous waste. Pesticide application equipment, if contaminated with residues or waste, could also be subject to strict regulatory measures, emphasizing the importance of proper cleaning and handling. Each of these items is managed under RCRA to ensure they do not negatively impact public health or the environment, while properly rinsed containers become a manageable, non-regulated material.
