STATISTICAL
INVENTORY RECONCILIATION TEST METHOD (QUANTITATIVE)
|
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.

|
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.

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.
