How many days do you have from a tank closure to report the UST checklist to ECY?

The requirement to report the UST checklist to the Department of Ecology (ECY) following a tank closure is set at 30 days. This timeline is crucial as it ensures that any potential environmental impacts are assessed and addressed in a timely manner.

Reporting within this timeframe allows for effective monitoring and management of any risks associated with released substances, which is a key responsibility in UST management. Staying within the 30-day window helps maintain compliance with regulatory obligations and facilitates communication with regulatory bodies about any necessary follow-up actions or remediation efforts that may be needed due to the closure.

Other options reflect longer timeframes that do not align with the regulations, emphasizing the importance of prompt reporting in maintaining environmental safety.
