USTMAN SIR 1.91
Statistical Inventory Reconciliation Test Method (Quantitative)
| Certification | Leak rate of 0.1 gph with PD = 98.4% and PFA = 1.6%. "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, 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 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. |
| Data Requirement | Minimum of 42 days of product level and flow through data. |
| Comments | Not evaluated using data from manifolded tank systems. Of 41 data sets submitted for evaluation, 4 data sets were not analyzed and 7 were inconclusive. Median monthly throughput of tanks evaluated was 10,978 gallons. Leak rates ranging from 0.048 to 0.201 gph were used in evaluation. Data sets evaluated were supplied by evaluator. |
