STATISTICAL INVENTORY RECONCILIATION TEST METHOD (QUANTITATIVE)

Certification Leak rate of 0.1 gph with PD = 99.8% and PFA = 0.02% for both single and manifolded tank systems.
"If a method meets the requirement for detecting a leak rate of 0.1 gph, it will meet the requirement for 0.2 gph.", according to "Standard Test Procedures for Evaluating Leak Detection Methods: Statistical Inventory Reconciliation Methods", EPA/530/UST-90/007, June 1990, Section 7.2.3, page 30.
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 0.1 gph (0.2 gph for the 0.2 gph test), 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 0.1 gph (0.2 gph for the 0.2 gph test) and the absolute value of the calculated leak rate is less than the leak threshold, the test result is "inconclusive."
Applicability Gasoline, diesel.
Other more viscous liquids may be tested after consultation with the vendor.
Tank Capacity Maximum of 60,000 gallons for single tank.
Maximum of 60,000 gallons cumulative capacity for manifolded tank systems with no more than 3 tanks in the system.
Data Requirement Minimum of 15 days of data is required.
System Features Method of data analysis that system employs, and was used during evaluation process, is exclusive of any external control by vendor.
System consists of a fully automated software package with embedded algorithms for conducting leak detection testing. Consequently, third party evaluation procedure demonstrated that system can be used in-house with no requirement for direct vendor participation.
Evaluation Features Evaluator tested this system for in-house use.
Computer program disk along with instructional documentation was supplied by vendor to evaluator.
Evaluator, without vendor involvement, analyzed required data and performed evaluation using program disk and accompanying documentation. Vendor was NOT present as an observer during evaluation.
Comments

46% of data sets evaluated were from manifolded tank systems.
Of 41 data sets submitted for evaluation, all were analyzed with conclusive results.
Median monthly throughput of tanks evaluated was 53,349 gallons.
Leak rates of 0.05, 0.10, and 0.20 gph were used in the evaluation.
Data sets evaluated were supplied by the evaluator.
According to vendor, TankMate Versions 3.12 and 3.20 are the same software.
