Guidelines on environmental requirements for large oil stores
The guidelines cover environmental requirements for storing oil products for sites with stores of mineral oil products above 2,500 tonnes.
The guidelines on environmental requirements for storing oil products cover activities under list points C 103 and C 201 in the Order of Environmental permitting. List point C 201 covers stores of mineral oil products of between 2,500 and 25,000 tonnes. List point C 103 covers stores of 25,000 tonnes and over.
The aim of the guideline is to support the environmental authorities in their approval and permit work involving oil stores. Therefore the primary target groups are the municipal environmental management administrations. Other target groups consist of energy enterprises with oil stores and private consultants.
The guidelines apply to stores of mineral oil. The environmental impact of stores of biofuels has not yet been fully explored, but has been identified. The guidelines thus cover tanks containing the following types of oil:
- Petroleum, feedstock products, middle distillates (e.g. vacuum gas oil (VGO))
- Refined products: Motor fuels, fuel oil and lubricating oil. Petrol, petroleum (including aviation turbine fuel), gas oil (including heating oil and diesel fuel), fuel oil and lubricating oil. Blended oils, including oxygenates, bioethanol and biodiesel.
Oil stores that must be approved are delimited as follows:
- Oil stores within the activity, i.e. within the property boundary or the within borders of land leased by the enterprise.
- Product pipes for transfer of oil between the oil store and piers or wharfs, and pipework within the activity.
- Loading and unloading facilities on piers and wharfs.
The guidelines should be used by the approvals authority as a basis for environmental approval of new oil stores in Denmark. Expansions or modifications to existing facilities are generally subject to the same rules as are applied for environmental permits for a new facility. These stores should have an environmental permit at the time of writing, although the Environmental Protection Agency is aware that the approval process has not been completed for all stocks.
However, immediately requiring the same organisation and management of an existing facility as that required for a new facility may be too comprehensive from a technical and financial standpoint. With regard to these facilities, the guidelines may provide the authorities, owners and managers with ideas for pollution prevention measures that may help to improve the environmental standard of the existing facility both immediately and in the longer term.
The guidelines, is structured as a reference tool, and outline the types of stores that are covered, the environmental legislation that applies to large oil stores, the most important environmental conditions, requirements when applying for an environmental permit for both new and existing facilities, and the conditions of which people should be aware when a facility is applying for an environmental permit.
Finally, the guidelines describe the responsibilities and tasks of the authorities with regard to the supervision of oil stocks, how best to prevent major environmental disasters, and how best to minimise the environmental damage in the event of a major disaster. The three annexes attached contain a list of potential environmental effects, suggestions for self-monitoring and a set of examples with suggested conditions for large oil stores.
