shall include certification from an independent 3rd party that the method has been evaluated in accordance with the applicable EPA standard test procedure for evaluating the method.
ATCP 93.130 Note
Note: EPA test protocols require precision tightness testing for tanks to be capable of detecting a 0.1 gallon per hour leak rate from any portion of the tank that routinely contains product when the tank is 95 percent full, with a probability of detection of 0.95 and probability of false alarm of 0.05. Precision tightness testing for piping must be capable of detecting a 0.1 gallon per hour leak rate, at a pressure of 1.5 times the operating pressure, with a probability of detection of 0.95 and a probability of false alarm of 0.05. Automatic tank gauges and all methods of monthly monitoring must be capable of detecting a 0.2 gallon per hour leak rate from any portion of the tank that routinely contains product with a probability of detection of 0.95 and probability of false alarm of 0.05.
The test methods shall be capable of detecting the minimum leak rate with the required probability of detection and false alarm, while accounting for the effects of thermal expansion or contraction of the product, vapor pockets, tank deformation, evaporation or condensation, and the height of the water table.
Manufacturers of leak detection methods shall specify what threshold leak rate is used with their test methods to indicate a leak.
ATCP 93.130 Note
Section ATCP 93.515 (5) (b)
requires automatic tank gauges to be provided with a printer that prints out the measured leak rate, and to state whether that leak rate indicates an actual leak in the system.
