UST Facility Inspections

The federal Energy Policy Act requires that all UST facilities are inspected no less than once every three years. During routine inspections, the ADEQ inspector will look at the entire facility, including the sumps, under dispenser containment and release detection equipment. The ADEQ inspector will also review records of financial responsibility, walkthrough inspections, required testing and maintenance. 

If deficiencies are found during the inspection, the facility will receive documentation on what needs to be corrected, and be provided the contact information of a compliance officer that will assist in resolving the issue.

Delivery Prohibition

On Jan. 1, 2009, state statute¹ gave ADEQ the authority to issue a stop-use order to the owner and operator of an Underground Storage Tank (UST) system if the UST is in violation of Arizona's UST rules and regulations. The continued operation of the UST may result in a continued release or a new release from the UST. The stop-use order becomes effective immediately on issuance and suspends the use of the underground storage tank until the owner and operator has returned the UST to full compliance with Arizona's UST rules and regulations.
