Statistical Inventory Reconciliation Test Method (Quantitative)
Detector
| Certification | Leak rate of 0.2 gph with PD > 99.3% and PFA < 0.7% for single tanks. Leak rate of 0.2 gph with PD > 99.9% and PFA < 0.1% for manifolded tanks. |
|---|---|
| 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." |
| Applicability | Gasoline, diesel. Other more viscous liquids may be tested after consultation with the vendor. |
| Tank Capacity | Maximum of 18,000 gallons for single tanks. Maximum of 45.000 gallons cumulative capacity for manifolded tank systems with no more than 4 tanks in system. |
| Data Requirement | Minimum of 28 days of product level and flow through data.. |
| Comments | 54% 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 18,897 gallons. Leak rates of 0.05, 0.1, and 0.2 gph were used in evaluation. Data sets used in this evaluation were supplied by evaluator. Inventory data used in this evaluation were obtained from manual tank stick readings and automatic tank gauge readings. Manufacturer also provides Leoma™ as an "in-house" product that licenses PC hardware and software. This "in-house" SIR product creates SIR reports based on SIR Phoenix LEOMA V01.50. Remote sites/stations enter data over ordinary phones into the Leoma� PC database which uses a voice recognition system. |
