Various types and volumes of petroleum products are stored in storage tanks above and below ground. These tanks vary in size and shape, and can be constructed single or double walled from materials such as steel, concrete or fiberglass. A public notice was issued in October of 1986 identifying petroleum storage sites having a total storage capacity of 2000 litres or greater, and marinas having a system with a total capacity of 200 litres, as being a "danger of pollution" under the "Clean Environment Act", and therefore requiring registration.
An approval must be obtained from the Minister of the Environment and Local Government prior to the installation of a petroleum storage system, that, by itself, or when its volume is added to the volume of tanks currently on site, will have a capacity of 2000 litres or more.
