If an unauthorized release meets reporting requirements, within how many hours must verbal notification be made?

1. 24 hours

2. 48 hours

3. 72 hours

4. 5 days

The correct answer is: 24 hours

Verbal notification for an unauthorized release that meets reporting requirements must be made within 24 hours. This timeframe is critical for ensuring that appropriate measures can be taken promptly to address the potential hazards associated with the release. Timely reporting is essential not only for the safety of the environment but also for public health. When an unauthorized release occurs, immediate action can help mitigate the risks involved, such as contamination of air, soil, or water resources. Reporting within this specific window is also aligned with regulatory compliance and ensures that response teams can deploy to assess and alleviate any potential impacts as quickly as possible. Other timeframes, like 48 hours, 72 hours, or 5 days, would not meet the immediate needs for response and monitoring required in situations of environmental risk, which is why they do not align with the requirement of a 24-hour notification window.
