Welcome to Washington Tank Operator Training (WATOT), the Washington State Department of Ecology’s site-specific online training and re-certification tool. This training covers information that is specific to your underground storage tank (UST) system and provides Class A/B operators an opportunity to be re-certified.

When finished with the training, you will be quizzed on the information that was covered. If you pass this short test, you will receive a site-specific Class A/B Certificate of Completion which can be printed and kept with your records. Another benefit of WATOT is it prepares a site-specific Operation and Maintenance (O&M) Plan that can be printed at the end of the training session. The O&M Plan can also be used to train new tank operators about the UST systems at your site.
