Washington UST Operator Training

Washington UST Class A B & C Operator Training

Washington Underground Storage Tank (UST) Class AB & C Certification

State Requirements
As required by the EPA, all UST operators must be trained by October 13, 2018. After this date, new Class A and B operators must be trained within 30 days of assuming duties. Class C operators must be trained before assuming duties.

Section 1524 of the Federal Energy Policy Act of 2005 required that the state of Washington declare amendments to the state underground storage tank rules to require each underground storage tank facility have Class A, Class B, and Class C operators.  Class A or Class B operator candidates will need to pass a written exam in order to be certified. The exam assures that underground storage tank system operators possess the necessary knowledge regarding the proper operation of underground storage tank systems. A test is not required for the Class C operator, but those persons must be properly trained.

The Washington State Department of Ecology (Ecology) revised the state UST rule (Washington Administrative Code (WAC) Chapter 173-360-700) to include the tank operator training requirements.

WAC 173-360-710 Designation of operators.
UST system owners and operators shall designate individuals as Class A, Class B, and Class C operators in accordance with the requirements of this section.

  • (1) At least one Class A and one Class B operator must be designated for each UST system or group of systems at an UST facility.
  • (2) Each individual who meets the definition of Class C operator at an UST facility must be designated as a Class C operator. Class C operators must be employees of the UST system owner or operator.
  • (3) Separate individuals may be designated for each operator class or an individual may be designated to more than one operator class.

If operators are not certified, the owner and/or operator may be subject to penalties.  If your UST system is found to be out of compliance, the Class A/B operator may be required to retake the training and/or provide an Operation and Maintenance Plan for the UST facility.

A record of each operator’s training certificate must be kept onsite. The documentation and/or certificates must include the facility address, Tag number, name of individual, date assumed duties, and date completed training. During an inspection you will be asked to provide:

  • Class A/B certificate (or if separate training, Class A and Class B certificates)
  • Class C certificate or documentation (optional blank form to fill out Class C Operators Certificate)

Washington was granted state program approval (SPA) in 1993.

Retraining Requirements
WAC 173-360-740 Retraining requirements for Class A and Class B operators.
UST system owners and operators shall ensure that Class A and Class B operators are retrained, as applicable, in accordance with the requirements of this section.

  • (1) Applicability. If the department determines the owners and operators of an UST system are not in compliance with the requirements of this chapter, the department may require the Class A and Class B operators of that system to be retrained in accordance with subsection (2) of this section. However, this provision does not apply to Class A and Class B operators who are retrained annually using a training program or examination meeting the requirements in WAC 173-360-730(1).
  • (2) Requirements. Within sixty days of receipt of the department’s determination of noncompliance, Class A and Class B operators requiring retraining must successfully complete a training program or comparable examination meeting the requirements in WAC 173-360-730(1) and submit a copy of the certificate of completion to the department. At a minimum, the retraining must cover the areas determined to be out of compliance.

As a result of the retraining of Class A operators or Class B operators, subsequent re-training of the Class C operators shall also occur. Voluntary refresher training is encouraged to ensure operator is up-to-date with current regulations and procedures.


UST Course Information

UST Class A/B Course Description
The UST Class A/B operator training course is presented in chapters. Each chapter utilizes multimedia to enrich the learning experience. Each chapter is followed by a quiz. If the student answers a quiz question incorrectly, the quiz feedback redirects the student to the correct course information.

In addition to the quizzes, the UST Class A/B operator training course includes a final exam of 100 questions, 80% of which must be answered correctly in order to print a certificate.

There is not any time restriction to access the course, so students can complete the entire course in a single session (approximately 4 hours plus exam time) or take the course in segments.

UST Class C Course Description
The UST Class C operator training course consists of seven chapters. Each chapter is followed by a short quiz. Once a student has completed all chapters and quizzes, the learner will be directed to print out a course checklist.

The course is instructed through a student orientation tour of a mock facility, where a manager (or Class B Operator) will identify and explain each topic and then mark them off a checklist when completed.  When the checklist has been completed, the student can then print the UST Class C operator certificate.

There is not any time restriction to access the course, so students may take as much time as needed to complete their training
