Unloading of petrol into storage at service stations and
regulation of the storage of petrol and dispensing of petrol in
order to reduce the emissions of volatile organic compounds (VOCs)
by recovering the vapour.
The Petrol Vapour Recovery Stage I (PVRI) Directive aims at
minimising VOC emissions from the storage of petrol at petrol
stations, from loading and unloading at petrol stations. There are
limited exclusions from the scope of the directive, mainly related
to the size of the petrol station.
The Petrol Vapour Recovery Stage II (PVRII) Directive just deals
with VOC emissions from refuelling – filling vehicles with petrol.
It has effect from 1 January 2012. However, in England vapour
recovery for refuelling operations at larger petrol stations with
an annual petrol throughput of 3,500 cubic metres (m3)/3.5 million
litres is already a requirement.
