SCHEDULE 3 REQUIREMENTS FOR FUEL OIL STORAGE AREAS

1.  The requirements to be satisfied in relation to a fuel oil storage area are as follows.

2.  The storage area must be surrounded by a bund capable of retaining within the area—

(a) if there is only one fuel storage tank within the area and fuel oil is not otherwise stored there, a volume of fuel oil not less than 110 per cent of the capacity of the tank;

(b) if there is more than one fuel storage tank within the area and fuel oil is not otherwise stored there, a volume of fuel oil not less than the greater of—

(i) 110 per cent of the capacity of the largest tank within the area; or

(ii) 25 per cent of the total volume of such oil which could be stored in the tanks within the area;

(c) if there is no fuel storage tank within the area, a volume of fuel oil not less than 25 per cent of the total of such oil at any time stored within the area;

(d) in any other case, a volume of fuel oil not less than the greater of—

(i) 110 per cent of the capacity of the fuel storage tank or, as the case may be, of the largest tank within the area;

(ii) if there is more than one fuel storage tank within the area, 25 per cent of the total volume of such oil that could be stored in the tanks within the area; or

(iii) 25 per cent of the total volume of such oil at any time stored within the area.

3.  The bund and the base of the area must be—

(a) impermeable to water and oil; and

(b) designed and constructed so that they are of sufficient strength and structural integrity so that with proper maintenance they are likely to remain so for at least 20 years.

4.  Every part of any fuel storage tank must be within the bund.

5.  Any tap or valve permanently fixed to the fuel storage tank through which fuel oil can be discharged to the open must—

(a) also be within the bund;

(b) be so arranged as to discharge vertically downwards; and

(c) be shut and locked in that position when not in use.

6.  If fuel from the tank is delivered through a flexible pipe that is permanently attached to the tank, the pipe must be—

(a) fitted with a tap or valve at its end that closes automatically when not in use; and

(b) locked in a way that ensures that it is kept within the bund when not in use.

7.  No part of the fuel storage area or the bund enclosing it may be situated within 10 metres of any inland freshwaters or coastal waters that fuel oil could enter if it were to escape.
