Environmental FAQ
Oil Storage
Will a double-skinned tank fulfil the Oil Storage
Regulations?
No, not entirely. A double skinned tank (a tank with a second
‘skin’ around it and a small gap between the two layers) may not
contain any of the pipe work or ancillary equipment; the
containment of which is central to the Oil Storage Regulations. A
tank will not be compliant unless ‘secondary containment’ is
provided for the tank and all its ancillary equipment.
How do I remove rainwater from the bund?
A collection sump should be included in the base of the bund;
although rainwater will often naturally evaporate from an open
bund, any that accumulates should be removed using a manually
operated pump or by bailing from the sump. As this water may be
contaminated it should be disposed of via a registered waste
carrier and treated as hazardous waste. It may be more
cost-effective in the long-term to provide cover for the bund. If
there is no rainwater in the bund after a period of heavy rainfall
this may indicate a leak, the tank should be inspected and
repaired.
