Pressurized piping installed on or before April 11, 2016, must meet the following requirements:
If the underground storage tank (UST) has suction piping that was installed on or before April 11, 2016, the release detection requirements will depend on which type of suction piping the owner and operator has. If the owner or operator can show that their suction piping has characteristics listed below, the piping will not need release detection.
Suction piping that does not exactly match the characteristics noted above must have release detection, either monthly monitoring or tightness testing of the piping every three years.
Piping installed or replaced after April 11, 2016, must have secondary containment with interstitial monitoring, except suction piping that has the characteristics listed above. In addition, pressurized piping must have a device that automatically shuts off or restricts flow or triggers an alarm that indicates a leak.
