Provided that the total capacity of tanks in any one walled enclosure shall not, without the written permission of the licensing authority, exceed 40,000 water tons. Where one tank is in one enclosure, the capacity of such enclosure shall be 100 per cent of the tank capacity. Where two or more tanks are in one walled enclosure the capacity of the enclosure shall be 100 per cent of the largest tank, plus ten per cent of the combined or aggregate capacity of the remaining tanks. The distance between such tanks shall not be less than the diameter of the smaller tank or fifty feet whichever is the less.

All aboveground tanks storing non-dangerous petroleum may be required by the licensing authority to be completely surrounded by an oil-retaining wall of a height required by the licensing authority, and so constructed as to collect spillage and prevent the escape of such non-dangerous petroleum from an installation. The distance between such tanks shall not be less than ten feet.
(3)
Except for the necessary pipes and valves the space within an oil-retaining wall not occupied by tanks shall be kept entirely clear and unoccupied and no water shall be allowed to accumulate therein.
