Petroleum Licensing

Petroleum Classes

In the regulations petroleum is defined as being one of three Classes, namely: 
• Class I Petrol
• Class II Kerosene/paraffin
• Class III Diesel/DERV/Central Heating Oil

Petrol Stations

Kildare County Council issues licences under the Dangerous Substances (Retail & Private Petroleum Stores) 1979 - 2008 Regulations.
Licensable premises include (a) petrol stations that dispense petrol through retail transactions on a forecourt and (b) commercial sites that dispense petrol for consumption by employees.

Storage of Petrol (i.e. Class 1 above) above certain thresholds requires a Petroleum Licence to be obtained from the local authority. The thresholds are listed in Section 21 of the Dangerous Substances Act 1972 

DSA Application forms and details of the cost of a DSA Application are available at the bottom of this page.‌

Details of the documentation that must accompany an application are listed in Section 12 of S.I. 311/1979.

Bulk Petrol Storage

Kildare County Council issues licences under the Dangerous Substances (Bulk Petroleum Stores) Regulations, 1979. These typically apply to large and medium sized bulk storage facilities where large quantities of Petroleum Class I are stored, sometimes in conjunction with Petroleum Class II and/or III, for subsequent delivery to retail petrol stations. Application forms are available on request from Kildare Fire Service,

Vapour Recovery Requirements

If you are a Petrol Station owner/operator you are obliged to ensure that your facility is so designed and operated in accordance of the Third Schedule of
Air Pollution Act 1987 - Petroleum Vapour Emissions Regulations S.I. 375/1997.

Petrol Interceptor / Oil Separator

Regulation 15 of the Dangerous Substances (Retail & Private Stores) Regulations 1979-2008 outlines requirements for Petrol Interceptors / Oil Separators.

Historically an interceptor was an interconnected 3-chamber unit. The licensing authority will generally accept designs according to a functional class determined by IS EN 858-2 and performance criteria as determined by IS EN 858-1 as meeting the requirements of Regulation 15(4).

A dedicated interceptor/separator is required to process the run-off from forecourt and/or bulk delivery tanker hard stand area. The chosen separator must have an oil/petroleum retention capacity for the spillage risk in the designated coverage area.

If the interceptor/separator is for use in the forecourt dispensing area only, an oil/petrol retention capacity comparable to the maximum amount of product that is likely to be spilled (usually the maximum that can be dispensed in a single retail transaction) would be sufficient.

If it is designed to cover the dispensing and tanker hard-stand areas, then it must be sized to fully retain the worst case scenario of the catastrophic failure of a petroleum storage compartment (usually in the range 5000 to 7000 litres) on a bulk delivery tanker. The pass-through waste water capacity is based on the peak rainfall falling on the designated surface area.

As one of the intended functions of a petrol separator is to retain a Class I petroleum spillage, it would in such circumstances in fact be a temporary underground petrol storage tank. Therefore, a petrol interceptor must be installed and surrounded with secondary containment (concrete vault/encasement) and be provided with petrol vapour vent management.

Under no circumstances should the waste water from a vehicle wash be directed into a petrol separator. Vehicle wash waste water must be processed separately in keeping with the effluent requirements of the overall site.

As well as meeting the regulatory requirements, a properly sized and maintained interceptor can reduce the risk of subsequent pollution in the event of an incident.
In fact a poorly maintained interceptor may be interpreted as providing a risk to the surrounding groundwater and may be the cause of the initiation of legal proceedings under the Water Pollution Act 1997 & 2000 quite separate from any sanctions that may arise from a proven breach of the Dangerous Substances Regulations and deemed to be an offence under the Dangerous Substances Act 1972.
