Leak rate of 0.2 gph with PD = 96.3% and PFA = 3.9%.

Leak Threshold

If the absolute value of the calculated leak rate (gain or loss) is less than the leak threshold and the minimum detectable leak rate is less than or equal to 0.2 gph, the test result is "pass." If the absolute value of the calculated leak rate is greater than or equal to the leak threshold, the result is "fail." If the minimum detectable leak rate exceeds 0.2 gph and the absolute value of the calculated leak rate is less than the leak threshold, the test result is "inconclusive."


Gasoline, diesel. 
Other more viscous liquids may be tested after consultation with the vendor.

Tank Capacity

Maximum of 15,000 gallons.

Data Requirement

Minimum of 35 days of product level and flow through data.


Not evaluated using manifolded tank systems. 
Of 120 data sets submitted for evaluation, 15 were inconclusive. 
Median monthly throughput of tanks evaluated was 15,867 gallons. 
Data sets evaluated were supplied by evaluator.

This method does not meet the Federal UST requirement for Statistical Inventory Reconciliation to report a quantitative result with a calculated leak rate. (40 Code of Federal Regulations, part 280.43(h)(1).)
