Tank tightness test data must be maintained until the next test is performed. Which of the following best restates this EPA requirement?

• A. 18 months
• B. 3 years
• C. 5 years
• D. Until the next test is performed

Answer: (D)

The key idea is that records of tank tightness testing stay in your files and remain the official record for the period until you conduct the next test. This ensures there’s a continuous, auditable history showing the tank’s condition between tests, so inspectors can verify compliance for the interval from one test to the next. Once you perform the next test, new data become the current record and you can update the file accordingly, but you still keep the prior test data as part of your overall testing history. The other fixed time options don’t capture the regulatory requirement, which is tied to the testing schedule rather than a set number of months or years.
