INTRODUCTORY NOTE
This does not form a part of the Environmental Permit.
The following Environmental Permit is issued under the Environmental Permitting (England
and Wales) Regulations 2007, (SI2007/3538) to operate an installation carrying out an
unloading of petrol into storage at petrol stations activity listed in 1.2 Part B (d) of Part 2 of
those Regulations, to the extent of the Environmental Permit. The emissions to air that
require control are volatile organic compounds in particular benzene.
The Environmental Permit specifies conditions that must be complied with. The Operator
shall use the “best available techniques” (BAT) for preventing or, where that is not practical,
reducing emissions from the installation. Techniques include both the technology used and
the way in which the installation is designed, built, maintained and operated. The
Environmental Permit has been prepared in accordance with the best available techniques
stipulated in the Secretary of State’s Process Guidance Note 1/14 (06) ‘Unloading of Petrol
into Storage at Petrol Stations.’
Description of Environmental Permitted Installation
BP Euston is permitted to unload petrol into five petrol storage tanks, equipped with a
vapour recovery system (Stage 1) to control displaced vapours during petrol filling
operations. The key air emissions from this activity that warrant control are petrol vapours
including benzene.
General Statutory Requirements
Proposed change in the operation of the installation
If the Operator proposes to make a change in the operation of the installation, the London
Borough of Camden shall be notified within 14 days prior to making the change. If the
proposed change requires any Environmental Permit conditions to be varied, an application
for variation will have to be made to the London Borough of Camden, in accordance with
Regulation 20 of the Environmental Permitting Regulations (EP Regulations).
Surrender of the Environmental Permit
Where an Operator intends to cease the operation of an installation (in whole or in part) the
London Borough of Camden shall be informed in writing, such notification must include the
information specified in Regulation 24 of the EP Regulations.
Revoke of Environmental Permit
The London Borough of Camden may revoke the Environmental Permit in part or in whole.
In accordance with Regulation 22 the Environmental Permit ceases to have effect on the date
specified in the notice.
Transfer of the Environmental Permit or part of the Environmental Permit
Before the Environmental Permit can be wholly or partially transferred to another person, a
joint application to transfer the Environmental Permit has to be made by both the existing and
proposed holders, in accordance with Regulation 21 of the EP Regulations. A transfer will
not be allowed where the Regulator considers that the proposed holder will not be the person
who will have control over the operation of the installation or will not ensure compliance

Interpretation of Terms
For the purpose of this Environmental Permit the following definitions shall apply.
“Authorised officer” - any person authorised by the London Borough of Camden under section
108(1) of the Environment Act 1995 to exercise, in accordance with the terms of any such
authorisation, powers specified in Section 108(4) of the Act.
“VOC” – any organic compound having at 293.15 a vapour pressure of 0.01 kPa or more, or
having a corresponding volatility under the particular conditions of use.
Explanatory Notes
Explanatory Note 1
With regards to Condition 30 the following types vapour recovery system can be installed:
A- Open Active Vapour Recovery with Return of Vapours to Underground Storage Tank
When petrol enters the vehicle tank, an active vapour recovery system (open active petrol
vapour recovery system) uses a vacuum pump to suck a corresponding volume of vapours back
into a storage tank.
Components of an open active petrol vapour recovery system may include:
•
A vapour recovery nozzle;
•
A hose through which vapours are collected (coaxial or similar) and a pipe through which
the vapours are returned (this may be separate from the fuel line or may be inserted into the
fuel line);
•
A vacuum pump;
•
A system to control the ratio of the volume of vapour recovered to the volume of
petroldispensed into the vehicle tank;
•
A vapour storage tank (i.e. the petrol storage tank).
The control of the ratio of the volume can be achieved by
• A proportional valve controlled either hydraulically or electronically; or
• Controlling the speed of the vacuum pump
B - Active recovery of vapours as petrol at the dispenser
Alternative vapour recovery systems may be used, in which petrol vapours are recovered at the
dispenser and returned direct for re-sale. Such equipment may include:
•
•
•
Standard nozzles and hoses designed for petrol vapour recovery as used where the vapours
are returned to the underground storage tank;
A vacuum pump which sucks the vapour through the nozzle and hose;
A heat exchanger which condenses the petrol vapours and a tank in which water is
separated and the recovered petrol stored. The recovered petrol is then passed to the
dispenser petrol lines during refilling.
10
London Borough of Camden
Environmental Permit - BP Euston Filling Station- PPC17/08
C - Passive vapour recovery
‘Passive’ or ‘balance’ vapour recovery systems do not include a vacuum pump. Instead, the
pressure exerted by the displaced petrol vapours is used to drive the vapours back into the
storage tank. In such a system, a rubber bellows/boot is required in order to ensure that there is
a seal between the vehicle and the nozzle. These systems require greater control on the part of
the vehicle owner in ensuring an adequate seal and are generally seen as being more unwieldy
than the techniques referred to above.
Explanatory Note 2
The automatic monitoring system referred to in Condition 34 shall:
a) Automatically detect faults in the proper functioning of the petrol vapour recovery
system including the automatic monitoring system itself and indicate faults to the
operator. A fault should be deemed to be present where continuous monitoring during
filling of vehicle petrol tanks indicates that the V/P ratio averaged over the duration of
filling has fallen below 85% or has exceeded 115% for ten consecutive filling
operations. This only applies to filling operations of at least 20 seconds duration and
where the rate of petrol dispensed reaches at least 25 litres per minute.
b) Automatically cut off the flow of fuel on the faulty delivery system if the fault is not
rectified within 1 week.
c) Be approved for use under the regulatory regime of at least one European Union or
European Free Trade Association country.
