Learn UST Compliance & Test Yourself

This study center helps owners, operators, and service technicians build durable knowledge of underground storage tank (UST) compliance. The material is grounded in the federal UST regulations at 40 CFR Part 280 and the programs that state agencies use to implement them, covering core topics such as release detection, spill and overfill prevention, corrosion protection, operator training classes (Class A, Class B, and Class C), and recordkeeping requirements.

Learning uses spaced repetition, a study method that schedules each flashcard for review at increasing intervals based on how well you recall it, so facts you find difficult resurface more often and facts you know well are spaced further apart. Reviewing a small set of cards consistently is far more effective for long-term retention than cramming, which makes spaced repetition well suited to the detailed testing intervals, deadlines, and definitions that UST compliance depends on.
