RECONCILIATION TEST METHOD (QUANTITATIVE)
||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
||0.1 gph for both
single and manifolded tank systems.
A tank system should not be declared tight if the test result indicates a
loss or gain that equals or exceeds this threshold.
Gains (water ingress) are analyzed and evaluated on an individual basis.
||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.
||Minimum of 28
days of product level and flow through data.
||54% of data sets
evaluated were from manifolded tank systems.
Of 41 data sets submitted for evaluation, all were analyzed with
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.
