STATISTICAL
INVENTORY RECONCILIATION TEST METHOD (QUALITATIVE)
Certification
|
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." |
Applicability
|
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.
|
Comments
|
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).)
