STATISTICAL INVENTORY
RECONCILIATION TEST METHOD (QUANTITATIVE)
| Certification |
Leak rate of 0.2
gph with PD > 99.9% and PFA < 0.1% for leak threshold of 0.1
gph.
Leak rate of 0.2 gph with PD > 97.2% and PFA < 0.1% for leak
threshold of 0.16 gph. |
| Leak
Threshold |
0.1 and 0.16 gph
for leak rate of 0.2 gph.
These leak thresholds are for evaluation
purposes only.
A tank system should not be declared tight if the test result indicates a
loss or gain that equals or exceeds the leak threshold calculated from the
data set. This leak threshold may be different than the above leak
thresholds. |
| Applicability |
Gasoline, diesel,
kerosene.
|
| Tank
Capacity |
Maximum of 45,000
gallons for single tanks.
Maximum of 45,000 gallons cumulative capacity for manifolded tank systems
with no more than 4 tanks in the system. |
| Data
Requirement |
Minimum of 23
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 |
This system was
tested for in-house use.
Vendor, with evaluator present, analyzed required data and performed
evaluation using program disk only.
Results were presented to evaluator directly from the computer without
additional vendor involvement. |
| Comments |
Gains (water
ingress) are investigated using current and previous month raw inventory
data.
73% of data sets were from manifolded tank systems.
Of 41 data sets submitted for evaluation, 4 were inconclusive.
Median monthly throughput of tanks evaluated was 22,370 gallons.
Leak rates of 0.05, 0.1, and 0.2 gph were used in evaluation.
Data sets evaluated were supplied by evaluator. |
