UST Operator Certification Procedures

Class A/ B Operator Training
PASS' A/B Operator Training in Arizona is approved by ADEQ
Class C Operator Training
PASS' C Operator Training in Arizona is approved by ADEQ

All of PASS’ UST operator training courses meet and exceed the federal requirements for UST operator training and are offered through our in-house designed and built Learning Management System (LMS). PASS’ state-specific A/B training courses are custom tailored to meet state requirements, and are accepted by more states than any other training provider.  Our courses are available on demand, 24/7 and are accessible from any internet-connected computer, tablet, or phone. The student can complete an entire course in a single session or take the course in segments. The training may be stopped and restarted, allowing for maximum schedule flexibility. PASS also does not impose time restrictions on course access, so students may take as much time as they need to complete their training.  Once training is completed a certificate is available to save and print.

Registration & Fees

Owners/operators of all USTs must register their USTs with the ADEQ within 30 days of bringing that UST into use by submitting a completed Notification for Underground Storage Tanks form (instructions for filling out this form can be found here).  Whenever any changes are made to the UST system, including change of ownership or change in product stored, an updated notification form must be submitted.

Release Reporting

Owners/operators must report suspected and confirmed releases to the ADEQ UST Call Line (800-234-5677 ext. 771-4303 or 602-771-4303) within 24 hours.  If the suspected release is a regulated UST spill or overfill of 25 gallons or less and that is contained or cleaned up within 24 hours, the UST owner/operator is not required to report the incident to ADEQ.  Within 14 days of discovering a suspected release, the owner/operator must submit a Release Status Report to the ADEQ.  For more information on responding to and reporting releases, see the ADEQ's release response information sheet.

Release Detection

UST owners/operators in Arizona may use any of the following methods of release detection.
  • Automatic Tank Gauge (ATG)
  • Secondary containment with interstitial monitoring
  • Statistical Inventory Reconciliation (SIR)
  • Manual tank gauging
  • Vapor monitoring
  • Groundwater monitoring
  • Tank tightness testing
  • Inventory control

Release Prevention

All UST systems that are filled with more than 25 gallons of a regulated substance at any time must have spill and overfill prevention equipment systems.  Spill prevention devices are called Spill Buckets or Catchment Basins.  The spill buckets should be sized so that it can hold more than the amount of product contained in the delivery hose. You must use one or more of the Overfill prevention methods below.
  • Automatic Shutoff Device - Automatically shuts off flow of fuel at 95 % or less of tank capacity.
  • Ball Float Valve - Restricts vapor flow out of the vent line at 90 % or less of tank capacity, or within 30 minutes before overfilling.
  • Overfill Alarm - Alarm activates when the fuel reaches 90 % of less tank capacity, or is within one minute of being overfilled.

Financial Responsibility

Arizona requires the following financial responsibility coverage amounts.  Owners/operators may use any of the following mechanisms to demonstrate financial responsibility.
  • Financial test of self-insurance
  • Guarantee
  • Insurance and risk retention group coverage
  • Surety bond
  • Letter of credit
  • Trust fund
  • Certificate of deposit
Owners/operators must submit an Underground Storage Tank Financial Responsibility form and documentation of financial responsibility coverage annually to the Arizona Department of Environmental Quality (ADEQ).  Owners/operators can find more information about Arizona's financial responsibility requirements on the ADEQ's financial responsibility page and in the ADEQ's financial responsibility brochure.

Inspection & Testing Requirements

The ADEQ and the Environmental Protection Agency (EPA) frequently coordinate on UST facility inspections.  The EPA has the authority to issue Field Citations and fine tank owners/operators at the time of inspection for violations of UST operational requirements.  In the event of an inspection, the inspector will usually want to see all paperwork regarding:
  • Operator training;
  • Notification, permit, and fees (as applicable);
  • Corrosion protection;
  • Overfill prevention;
  • Spill prevention;
  • Tank and piping release detection;
  • Financial responsibility;
  • Reporting of suspected releases;
  • Tank and/or piping maintenance and repairs;
  • Secondary containment (where required); and
  • Temporary closure.

Delivery Prohibition/Non-Compliance Enforcement

ADEQ has the authority to issue a stop use order to the owner/operator of a UST system if the UST is in violation of Arizona's UST rules and regulations and 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.

Facilities currently under a stop use order have delivery prohibition in effect and will be listed on the ADEQ's website.  Facilities will be removed from this list within five business days after the department determines that the facility has been returned to compliance.

Temporary & Permanent Closure

Temporary Closure
Underground Storage Tanks (USTs) may be temporarily closed for up to 12 months by following these requirements:

  •  Continue maintaining the UST system’s leak detection, and if your tank contains less than one inch of residue, you do not need to main- tain leak detection.
  • Maintain corrosion protection, if required.
If the UST system remains temporarily closed for more than three months but less than 12 months, the following additional steps must be taken:
  • Keep vent lines open; and
  • Cap and secure the following:
    •  pumps
    • manways
    • ancillary equipment
    • all other lines
    • ADEQ recommends you cap and secure sooner than three months.
Required Documentation: A Notification for Underground Storage Tanks Form must be submitted to ADEQ within 30 days after beginning Temporary Closure.

Permanent Closure
The following procedures must be followed for UST Permanent Closure:

  • Notify ADEQ in writing of your intent to close the UST at least 30 days prior to the closure date.
  • At this time, ADEQ will assign a closure number.
  • Coordinate with the appropriate fire authority and ADEQ for the date and time of actual closure.
  • Use a tank service provider certified by ADEQ to decommission the UST.
  • Perform a site assessment.
  • Submit the Notification Form and the site assessment report within 30 days of the permanent closure date.
For details, refer to the Permanent Closure Guidance Document at ADEQ’s website or contact the UST call line at (800) 234-5677 or (602) 771-4339.
