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 classified as "regulated waste" under the Federal Resource Conservation and Recovery Act (RCRA) when they have been treated correctly. Properly cleaning pesticide containers through a triple-rinsing process is a practice that helps ensure any residual pesticide is sufficiently diluted and disposed of safely, thereby qualifying the containers for disposal in a manner that is not considered hazardous waste. This practice minimizes environmental impact and promotes safe handling and disposal.

In contrast, excess pesticide and pesticide dilutions, rinsewater containing hazardous substances, and unclean application equipment pose greater risks in terms of toxicity and potential environmental contamination. These are considered regulated waste because they still contain hazardous chemicals that could harm the environment or public health if not disposed of according to stringent regulations. Thus, the correct understanding here highlights the importance of proper rinsing and disposal procedures to differentiate between regulated and non-regulated waste within the realm of pesticide application.
