INTERPRETATION

The following has effect with respect to this permit:

Environmental Health - means the Environmental Health Section of

Environmental Heath and Community Safety,

Reigate and Banstead Borough Council, Town

Hall, Castlefield Road, Reigate, Surrey, RH2 0SH

CONDITIONS:

PROCEDURES

1. Vapours displaced by the delivery of petrol into storage installations at service

stations shall be returned through a vapour tight connection line to the mobile

container delivering the petrol. Unloading operations shall not take place unless the

arrangements are in place and properly functioning, subject to Conditions 3, 4 and

5.

2. The operator shall implement the schedule of preventative maintenance, as

provided as part of the application for authorisation dated 15 January 1999, as set

out in Appendix II.

3. All reasonable practicable steps shall be taken to prevent uncontrolled leaks of

vapour from vents, pipes and connectors from occurring. Environmental Health shall

be advised without delay of the circumstances of such a vapour leak if there is likely

to be an effect on the local community, and in all cases such a vapour leak shall be

recorded in the log book required under condition 24.

4. The operator shall advise Environmental Health of the corrective measures to be

taken and the timescales over which they will be implemented in the event of a

vapour leak, described in Condition 3.

5. Instances of vapour lock shall be recorded in the log book and, under the

circumstances detailed in Condition 3, Environmental Health shall be advised

immediately.

MAINTENANCE SCHEDULE

Appendix C - Schedule of Maintenance, Testing and Examination of

Vapour Balancing Controls

A programme of Preventative maintenance to ensure the correct operation of the Vapour Containment system shall be implemented and undertaken by a competent person and shall include the following tasks;

Routine Inspection

The following components shall, where fitted, be visually inspected annually for wear, damage, blockage, leakage and freedom of operation:-

i) Vent system emission control device ii) Flame arresters iii) Vapour Hose Integrity iv) Vapour Hose Electrical Continuity v) Vapour Hose Connectors/Dust Caps vi) Vapour Connection point couplings including valves and lockable dust caps vii) Positioning and clarity of safety signs viii) Overfill and overspill prevention devices ix) Manifold drain

x) P/V valve functioning

Testing the Vent Valves The vent valves shall be removed and the following checked when any modification is made to the system (excluding routine component replacement) or if any leak or malfunction is suspected:-

i) The pressure setting should be 35 mbar ii) The Vacuum setting should be -2 mbar iii) The design flow rate should be appropriate for the mode of operation (e.g.

single hose off-loading 1000 litres per minute, two hose off-loading 2000 litres per minute)

The valves shall then be re-installed carefully to ensure a gas tight seal.

A record of all maintenance checks and inspections shall be made in the

relevant section of the Site Maintenance Log Book.

of 15

In addition to the above the Petrol delivery and Vapour return lines shall be

tested prior to commissioning and thereafter on a three yearly basis, or where a

malfunction is suspected, following the procedure detailed below:-

Testing the Tank and Vent System for Leaks (Manifolded system)

i) A blanking cap with pressure tapping shall be fitted in place of the vehicle

vapour hose connector (this will block off the vapour return to the vehicle so that vapour must exit through the tank vent system)

ii) The vehicle vapour hose shall be connected to the vehicle manifold to enable the interlocks but shall not be connected to the petrol filling station vent system. (The vehicle vapour manifold will now be open to atmosphere via the hose but since during off-loading air is drawn in rather than vapour forced out this is not a dangerous situation)

iii) All dispensing of product from the station shall be stopped and the

pressure in the underground tanks noted. (At this time it is likely to be at or just below atmospheric).

iv) The number of delivery lines to be discharged simultaneously shall be connected to the appropriate tanks and flow started as the pressure is monitored. (A manometer type pressure gauge suitable for measuring the low pressures involved, generally up to 70 mbar shall be used). (Provided that there is no leak in the system the pressure in the vapour spaces of the underground tanks will rise- this may be quite slow if there is a lot of ullage e.g. perhaps 1-2 minutes. It should rise to the pre-set level at which the pressure valve starts to open, then either hold at that level or rise to the 35 mbar point).

v) The flow from the tanker shall then be stopped and the pressure monitored. (It should drop back to the initial opening point of the pressure relief valve again and hold at that level - it should hold for 5 minutes. If there is a leak the pressure may not reach these levels and the source of the leak should be traced and repaired).

Checking for correct vapour flow in systems fitted with PN Valves (Manifolded Systems)

Once the vapour tightness of the petrol installation has been confirmed, the correct operation of the balancing system shall be confirmed:-

i} Fit the vapour connection point on the petrol filling station with a double

ended extension piece which will allow the vehicle hose to be connected but has a pressure tapping point.

ii) Connect a manometer type pressure gauge suitable for measuring the low level pressure involved, generally up to 70 mbar, to the pressure tapping point.

iii) Monitor the pressure and begin delivery in the usual way, using the maximum number of hoses it is intended •o use in operation. (Initially the

M:\ENVHEALT.H\EP\ENV-PROT\Work\Industrial Pollution Regulation\PPC Permitted Sites Records\Petrol Stations\RBBC.006- Chequers Service Station (Sainsburys)\Total_Chequers\006_Permit_V003__January 2015_Sainsburys3fin.docx

pressure may fall to below atmospheric as the preferential flow path is

developed, but should rise rapidly to above atmospheric and remain

reasonably constant during the off-loading process).

From the results of the above we can make the following deductions:-

• The pressure stays below the pre-set valve opening pressure- it can be

concluded that the system is functioning satisfactorily.

• The pressure rises to the pre-set pressure of the valve (it may be possible to hear

vapour escaping from the vent) - in this case there is some sort of restriction in

the system downstream of the pressure tapping (i.e. in the hose or vehicle

system) -this will be investigated. (Note: the situation is safe since vapour will be

emitted through the vent stack).

• The pressure does not rise at all and stays slightly below atmospheric -the

vapour is not getting to the end of the manifold (i.e. the hose connection) -

there are several explanations for this:-

The product is not flowing into the tank. (I t is usually possible to hear

the product flowing in the delivery hoses)

The vapour may be escaping elsewhere (This possibility is unlikely if

the leak test has been carried out correctly). This must be investigated

immediately as vapour could be escaping at low level and therefore

constitute a safety hazard. Flow shall be stopped and the leak found.

The vent system may be blocked downstream of the point where the

tanks vents join the manifold or the vents from the tanks being filled

may be blocked. (most likely this will result in the product flow from the

vehicle stopping as the tank pressure rises to the static head pressure

in the vehicle compartments - this option is also unlikely if the leak test

has been done but if it does occur caution will be required since the

system is pressurised and the delivery hoses will be full of product).

Any problems discovered shall be investigated and rectified and the leak and

flow tests repeated. All testing shall be recorded in the relevant section of the

Site Maintenance Log Book.
