Does oil stored within a generator come under the regulations?
It depends on whether the oil is being stored or used. The regulations apply to generators where the oil is being stored rather than used, and where no exemptions apply. They will therefore apply to stand-by generators which are storing oil for later use. Sets containing more than 200 litres of oil would require secondary containment of the day tank. Bulk storage tanks greater than 200 litres that supply a standby generator or its day tank fall under the regulations because the oil is being stored but not used. Where a generator is in regular or constant use and its day tank is of a capacity such that the oil will be used during an operating day – even if the volume of oil is greater than 200 litres – the oil will be regarded as ‘in use’ and the regulations will not apply. But if oil is not all used up in the operating day it will be regarded as being stored and the regulations will apply if the tank holds over 200 litres. Even if the regulations do not apply the potential for environm
