Paragraph 2
The licensee shall, for the purpose of distinguishing one storage tank from any other storage tank situated at the licensed premises, ensure that every such tank is clearly marked with—
a number, a letter or a combination of both a number and a letter in such a manner that the number, letter or number and letter cannot be readily altered or obliterated; and
(adjacent to that number, letter or number and letter) the maximum working capacity of the tank and the grade of petrol permitted to be stored therein under the petroleum-spirit licence granted in respect of the licensed premises.
In this Schedule, any reference to the maximum working capacity of a storage tank shall be a reference to 97 per cent of its actual capacity, expressed in litres.
