In Washington State, what is the reporting time frame for a suspected UST release?

In Washington State, the reporting time frame for a suspected underground storage tank (UST) release is critically important for ensuring timely response and mitigation of potential environmental hazards. Reporting within 24 hours is mandated to allow regulatory agencies to promptly assess and address any risks posed by the release.

This timeframe ensures that investigations and remedial actions can begin as soon as possible, reducing the potential for contamination of soil and groundwater, which can pose serious health and environmental risks. By having a clear 24-hour reporting requirement, it encourages UST owners and operators to act swiftly, facilitating quicker response actions that align with public safety regulations and environmental protection measures.

The other options either extend the response timeframe unnecessarily or do not comply with state regulations, which emphasize immediate attention to suspected releases to prevent further environmental damage.
