What action is required by the owner/operator immediately following a suspected release?

The action required by the owner/operator immediately following a suspected release is to report to the Department of Ecology. This is crucial because timely notification allows for swift investigation and response to potential environmental hazards. Early reporting helps in coordinating the necessary actions to mitigate any contamination and protect public health and the environment. In Washington State, regulations require that any suspected release be communicated to the appropriate governing body so that they can provide guidance and assistance in handling the situation effectively.

While cleaning the area, inspecting the tank for damage, and informing the public may be important actions to take later on, the immediate necessity is to ensure that the relevant authorities are made aware of the situation. This allows for a structured response according to established protocols for managing environmental releases.
