Which of the following is NOT a possible consequence if the EPA decides a pesticide poses risks to humans?

The correct choice highlights that issuing fines to users is not a typical consequence the EPA would implement if it determines a pesticide poses risks to humans. When the EPA evaluates the safety and environmental impact of pesticides, their primary focus is on regulating the use of these chemicals to protect human health and the environment.

The other actions mentioned are standard responses to manage pesticides deemed hazardous. For instance, setting reentry intervals helps ensure that individuals can safely re-enter an area after pesticide application without risking exposure. Canceling or suspending pesticide use directly prevents further exposure and is a substantial regulatory action reflecting the seriousness of potential risks. Similarly, setting restrictions on application frequency limits how often a pesticide can be used, reducing the likelihood of adverse health effects.

Ultimately, while fines can be a part of regulatory enforcement, they are more commonly associated with violations of pesticide regulations than a direct response to a risk assessment regarding safety and health impacts. The core mission of the EPA is to mitigate risks rather than penalize users unless they fail to comply with existing regulations.
