STATISTICAL
INVENTORY RECONCILIATION TEST METHOD (QUALITATIVE)
|
Certification
|
Leak
rate of 0.2 gph with PD = 100% and PFA = 0% for Version
1.0.
Leak rate of 0.1 gph with PD = 100% and PFA = 0% for Version
2.0.

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
(0.1 gph for the 0.1 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 0.2 gph (0.1
gph for the 0.1 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 18,000 gallons.
|
|
Data
Requirement
|
Minimum
of 30 days of product level and flow through data.
|
|
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
present as an observer during evaluation.

Comments
|
Not
evaluated using data from manifolded tanks.
Of 120 data sets submitted for evaluation, 10 were inconclusive
for Version 1.
Of 120 data sets submitted for evaluation, 9 were inconclusive
for Version 2.
Median monthly throughput of tanks evaluated was 13,640
gallons for Version 1.
Median monthly throughput of tanks evaluated was 11,828
gallons for Version 2.
Leak rate of 0.2 gph was used in evaluation for Version
1.
Leak rate of 0.1 gph was used in evaluation for Version
2.
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).)
