8 CSLD PER. AUTO CSLD
9 NONE
Analysis
Tanks 8 and 9 were manifolded and programmed as manifolded. However, the leak test frequency selected for
Tank 9 was not CSLD. The CSLD program was only using Tank 8’s volume to perform the test. When Tank 9 was
filling, Tank 8’s LRATE was positive.
Solution
Set Tank 9’s Leak Test Method to CSLD and delete tank 8 and 9 rate tables.
