Washington Delivery Prohibition Program

How To Identify An Ineligible Underground Storage Tank:
Annual registration is required. The certificate of registration (facility compliance tag) should be posted on or near the fire emergency shutoff device or, if that is not possible, close to the fill pipe and clearly identifiable to persons delivering regulated substances to the underground storage tanks. A list of registered or tagged facilities is posted on the Washington Department of Ecology's Web site. Delivery and transfer of regulated substances are prohibited for tanks without facility compliance tags, at facilities known to be leaking, and for tanks that are known to be leaking, which have not been properly repaired. Green tag rules also apply to waste oil underground storage tanks.

The Department of Ecology will also be developing rules regarding a red tag program (see Substitute Senate Bill 5475 below). The red tag program will be tank specific. The existing facility compliance tags are issued to each underground storage tank facility. If a facility compliance tag is not posted, fuel must not be delivered to any of the tanks located at that facility or waste oil removed without prior approval from the Department of Ecology.
