Tank + Line Testing

What are the regulatory requirements for pressurized piping?

From The EPA's Website...

Each pressurized piping run must have one leak detection method from each set (A and B) below:

 

A. An Automatic Line Leak Detector:

  • Automatic flow restrictor; or

  • Automatic flow shutoff; or

  • Continuous alarm system.

 

B. And One Other Method:

  • Monthly interstitial monitoring; or

  • Monthly vapor monitoring; or

  • Monthly groundwater monitoring; or

  • Monthly statistical inventory reconciliation; or

  • Annual tightness test.

 

*Automatic Line Leak Detectors Require An Annual Inspection by A Qualified Technician

 

What are the regulatory requirements for suction piping?

From The EPA's Website...

No leak detection is required if the suction piping has the following characteristics:

  • the piping has enough slope so that the product in the pipe can drain back into the tank when suction is released, and the piping has only one check valve, which is as close as possible beneath the pump in the dispensing unit.

  • If a suction line is to be considered exempt based on these design elements, there must be some way to check that the line was actually installed according to these plans, that is those elements of #1 and #2 must be easily discernable.

  • If a suction line does not meet all of the design criteria noted above, one of the following leak detection methods must be used:

    • A line tightness test at least every 3 years; or

    • Monthly interstitial monitoring; or

    • Monthly vapor monitoring; or

    • Monthly groundwater monitoring; or

    • Monthly statistical inventory reconciliation.
