Please note the investigation for Tank 4 (Unleaded) at the site Petchkasem Soi 55/3 Wat Muang (10041737) has now been closed.
For your convenience please see below for the closing investigation note for this tank:
An investigation was opened and a request for a PLIP A was made on 07/08 due to tank having a low and deviating performance in the terminal banding. PLIP A received on 11/08, highlighting a fault with the height to volume conversion chart. I have queried what steps site have taken in order to resolve this. Site have stated they have in fact changed the dipstick at the end of July 2014. Performance appears to have improved over recent data. The tank has been monitored for over 2 weeks and improvements have been sustained.
