I believe 'stage 1" - for deliveries of fuel etc.. has been implemented.
Stage 2 -- anyone??

Consultation has taken place ....
That probably does more good than harm .... Probably best not to regularly brim at a 'stage 2' setup... If we have them.

DEFRA said:Petrol Vapour Recovery Controls
69. The Government also proposes to bring forward legislation to ensure that emissions of volatile organic compounds (VOCs) from vehicle refueling are properly controlled, which will reduced levels of benzene and ozone, (to which VOCs are a contributing factor). This follows European legislation which came into force in 1995 to control emissions of VOCs resulting from the storage of petrol and its distribution from terminals to service stations. This "Stage I" Directive applies to terminals, most transport containers (road and rail tankers and barges) and petrol service stations and requires the establishment of a 'closed' system of petrol storage and transportation, under which petrol vapours are recovered and then regenerated back into petrol.
70. Stage I legislation is effective as far as it goes, but it does not reduce emissions into the atmosphere during the process of vehicle refueling. A system can be fitted to the petrol pump to collect vapours not covered by Stage I controls and return them to the petrol storage tank under the forecourt. From there, the vapours will be recycled back into petrol at terminals by means of the Stage I controls.
71. The European Commission had intended to introduce a second Directive in this area, known as 'Stage II' legislation, but as a number of EU Member States have now either brought forward Stage II controls for service stations on a unilateral basis or have plans to do so, the Commission has dropped its plans for a Stage II Directive.
72. The Government intends to consult on its proposals for Stage II controls during 1999.
Consultation has taken place ....
Department for Environment, Food and Rural Affairs
Petrol Vapour Recovery Stage II - Consultation
Petrol vapour escapes when drivers fill their tanks at a service station. Petrol contains Volatile Organic Compounds (VOCs). VOCs are a precursor to ground level ozone, the main constituent of summer time smog. Exposure to ozone can damage crops and ecosystems, and presents a direct risk to human health. Benzene, for example, is a genotoxic human carcinogen. Petrol vapour recovery systems can be installed at service stations to reduce emissions of VOCs from vehicle refuelling; these are known as 'stage II' controls.
It is proposed to implement stage II controls in the UK by a limited negotiated agreement with UK industry.

Been reading odd snippets that 'filling to the gun' can draw metered fuel back into supply tanks with such 'stage II' systems - any knowledge ??ZVA Vapour Recovery Nozzle
This ZVA nozzle is for use on dispensers with a stage II vapour recovery system. Fitted with an unleaded spout and No. 4 guard. Fixed inlet to fit onto coaxial vapour recovery hoses.
