I have just purchased a petrol station and have started to operate it and would like to ask about the petroleum storage certificate (Psc) that has been issued for my site. I have 6 underground storage tanks, 3 of which are currently holding petrol, however, my storage certificate only shows the 3 petrol tanks? All the tanks are double skin steel with liquid leak detection, is this correct?

In a word no, there is a criterion that was published when the Petroleum (Consolidation) Regulations 2014 were introduced to assist petroleum enforcement authorities (PEA) to understand what tanks could be included on the PSC, the PSC must list all underground tanks that can legally hold petrol, even if they currently are used with another fuel.

This is to facilitate a grade change (petrol to diesel or vice versa) without the need to inform the PEA, as long as it is done in a safe manner and the vapour recovery is removed/replaced as required, the PEA would then pick this up on their next visit and amend their records accordingly.
