UST Operator Certification Procedures

Class A/B Operator Training
In Oregon, UST System Operators can only be certified after taking and passing the exam administered by the International Code Council (ICC) through Pearson VUE testing centers.  Getting ready for the ICC exam(s) is a three-step process

Step One: Take the PASS ICC Preparatory Course
PASS is the only training provider approved by the ICC to offer preparatory training for the ICC UST/AST operator exams.  These ICC preparatory courses do not include a final exam or provide certification upon completion and is not required to take, but they will provide you with the information and guidance you need to study and prepare for the exams.

Step Two: Read the UST/AST Examination Information Bulletin and Prepare Your Reference Materials
First, you should read the UST/AST Examination Information BulletinYou may also call the ICC at 1-888-ICC-SAFE (422-7233), ext. 5524 to request a paper copy of the Bulletin.
Pay particular attention to the information on your state’s exams. Specific exam information usually begins around page 24 in the Bulletin, and includes the number of exam questions, the exam fee, the type of exam, and the list of reference materials.
Most ICC UST/AST operator exams are open book, which means that you may take certain documents (called reference materials) with you into the exam room and refer to them during the exam. The ICC, however, has strict requirements about which reference materials you can take into the exam with you and in what format. PASS strongly recommends that you obtain your reference materials well in advance of taking the exam.
Which reference materials do I need? How do I get them?
The reference materials you need are listed in the UST/AST Examination Information Bulletin. They typically include the Environmental Protection Agency’s (EPA’s) UST regulations (40 CFR §280), the state’s UST regulations (which usually can be found on the state UST program’s website), and one or more of the following EPA publications, any of which can be downloaded here or through a PASS ICC preparatory course.
Your reference materials list may also include publications of the Petroleum Equipment Institute (PEI), which you must purchase through PEI’s online storeTypically, these include PEI/RP 500 Recommended Practices for Inspection of Motor Fuel Dispensing Equipment and PEI/RP 900 Recommended Practices for Inspection and Maintenance of UST Systems.  You may also be able to purchase these bundled with your state’s other reference materials through the ICC’s online store.
How do I prepare my reference materials? You may take only the reference materials listed in the current UST/AST Examination Information Bulletin with you into the exam. In order to be able to take them into the exam, you should prepare them as follows.
If you do not follow these steps, the Pearson Vue test center personnel will not let you take your materials into the exam room and you will not be able to use them during the exam.
  1. STAPLE OR BIND YOUR MATERIALS.  You may not take loose pages into the exam room, so we recommend that you print the reference materials and either staple them together or place them in a three-ring binder.
  2. MAKE NOTES. You may make notes in your reference materials as long as the notes are in ink and any highlighting is done before you arrive for the exam. For example, you should locate and mark in the reference materials information such as your state’s allowable release detection methods, allowable financial responsibility mechanisms, recordkeeping requirements, operator retraining requirements, etc. This will make it easier to find the information during the exam itself. PASS’ ICC preparatory courses make this easier by giving you rule citations or page numbers keyed to your reference materials.
  3. USE TABS.  You may also use tabs to mark important sections, but these tabs must be permanently attached and not be removable without damage to the page (removable post-it type tabs, for example, would not be allowed).
Step Three:  Schedule Your Exams
ICC exams are offered periodically at Pearson VUE testing centers around your state. When you are ready to take your exams, you can register online at or by calling Pearson VUE at 1-800-275-8301.

Oregon Post-Training Certification Procedures

  • Class A/B operators in Oregon need to take and pass the International Code Council’s (ICC’s) national Class A and Class B operator exams.  The Oregon Department of Environmental Quality (DEQ), however, requires A/B operators to submit their ICC score reports and review the Oregon training manual before being fully certified.  Here is what you need to do.
  • Once you have passed the ICC exams, you must submit copies of your ICC score reports and your phone number to:
            Mitch Scheel
            Oregon DEQ – Land Quality Division
            811 SW Sixth Avenue
            Portland, OR 97204
  • The DEQ will send you a copy of the Oregon-specific training manual, which you must read.
  • When you have finished reading the training manual, you must submit an affidavit stating that you have read and understood the manual.  Only then will you be in compliance with the training requirement.
Class C Operator Training
Class C Operator Training in Oregon is an accepted form of training for Class C Operators by the DEQ

Registration & Fees

Owners/operators of all USTs must register their USTs with the DEQ by submitting a completed Application to Install and Operate Regulated Tanks.  The form provides guidance on calculating the registration fee, which must be paid at the time of registration and annually thereafter.

Release Reporting

Owners/operators must report any suspected or confirmed releases to the Oregon Emergency Response System (1-800-452-0311).  Information on spill reporting and a downloadable Spill/Release Report Form can be found on the DEQ’s Environmental Cleanup page.

Release Detection

UST owners/operators in Oregon may use any of the following methods of release detection:
  • Manual tank gauging;
  • Automatic tank gauging (ATG);
  • Groundwater monitoring;
  • Vapor monitoring;
  • Secondary containment with interstitial monitoring; or
  • Tank tightness testing.

Release Prevention

  • For all UST systems installed or overfill equipment replaced on or after March 1, 2003, an owner and permittee must be able to provide visual verification that the overfill equipment functions as required by OAR 340-150-0310.  For overfill equipment installed before March 1, 2003, an owner and permittee must be able to demonstrate to the department that the equipment functions properly by any method deemed acceptable by the department.

Financial Responsibility

Oregon follows the federal financial responsibility coverage amounts found in 40 CFR §280.93 (scroll to page 77 of 119 in the pdf document).  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
  • Stand-by trust fund
Owners/operators may learn more by reading the DEQ’s fact sheet “Documenting Compliance with Financial Responsibility.”

Inspection & Testing Requirements

An inspector from the DEQ will periodically inspect each UST facility.  The inspector will 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 repairs;
  • Secondary containment (where required); and
  • Temporary closure.
Owners/operators can learn more about compliance inspections in the DEQ’s publication Preparing for an UST Compliance Inspection.

Delivery Prohibition/Non-Compliance Enforcement

If a DEQ inspector determines that a UST or UST system is out of compliance with UST regulations, he or she may initiate non-compliance enforcement procedures.  Tanks that are ineligible to receive fuel are listed on the DEQ’s website.

Temporary & Permanent Closure

Temporary Closure
  • You must notify DEQ within 30 days of placing your UST system into temporary closure by submitting a Notification of Temporary Closure of Underground Storage Tanks.
  • Upon receipt of a temporary closure notification, DEQ will issue a Temporary Closure Certificate that is valid for one year.  Before the year is up, a decision needs to be made to do one of the following:
  • Complete a change-in-service;
  • Permanently decommission the UST system;
  • Place the UST system back into operation; or
  • Ask for an extension of the Temporary Closure Certificate by submitting the form entitled Request for Extension – Temporary Closure of Underground Storage Tanks and the results of a current site assessment.

Permanent Closure
  • At least 30 days before beginning permanent closure, the owner and permittee, or the licensed service provider on behalf of the owner and permittee, must submit an application (forms available here) for a permanent closure general permit to the department.
  • If the owner or permittee is proposing to permanently close the UST in-place and fill it with an inert material or if the UST contains a hazardous substance other than petroleum, the application must include a written site assessment plan that meets the requirements of OAR 340-150-0180.  Permanent closure cannot begin until the department approves the site assessment plan.
  • At least three working days before beginning permanent closure, the owner and permittee, or the licensed service provider on behalf of the owner and permittee, must notify the department of the confirmed date and time permanent closure will begin to allow observation by the department.
  • The permittee must empty the UST system and clean it by removing all liquids and accumulated sludge.  The USTs and removed materials must be recycled or disposed of in accordance with all federal, state and local requirements.


  • Maintain records of all replacements and repairs for the life of the UST system.
