What action must be taken if a site assessor finds an unreported tank?

When a site assessor discovers an unreported tank, notifying the Washington State Department of Ecology (ECY) within 24 hours is essential because it is a regulatory requirement aimed at ensuring the safe management of underground storage tanks. Unreported tanks can pose significant environmental risks, including potential leaks and contamination. Prompt notification allows for timely investigation and remediation efforts, thus safeguarding public health and the environment.

Compliance with this requirement ensures that necessary measures can be taken in accordance with state regulations, which emphasizes the importance of maintaining accurate records of all USTs. This action also helps to enforce accountability among tank owners and operators, ensuring that they adhere to environmental standards and regulations. Therefore, timely reporting to the appropriate authority is essential in effectively managing any risks associated with unreported tanks.
