What are the regulatory requirements for tank tightness testing?

The tightness test method must be able to detect a leak at least as small as 0.1 gallon per hour with certain probabilities of detection and of false alarm.

Tightness tests must be performed periodically. New UST systems–those installed after December 1988–must have tank tightness tests every 5 years for 10 years following installation. In most cases, existing UST systems–those installed before December 1988–that have spill, overfill, and corrosion protection must have tank tightness tests every 5 years for 10 years following upgrade. There are only a few cases requiring fewer tightness tests. Existing UST systems that have not been upgraded must have tank tightness tests annually until December 1998, after which these tanks must be upgraded, replaced, or closed.

After the applicable time period noted above, you must have a monitoring method that can be performed at least once per month.
