Petrol, diesel and oil are the most common hazardous substances we encounter. These substances fuel our vehicles, homes and businesses. If these subtances are stored, handled or disposed of inappropriately, it can be a hazard to our health and environment.
Unlabelled or badly stored fuels and oil could be mistaken for drinks or toys by small children and pets. Badly stored and disposed fuels and oil can contaminate our soils, air and water. In Canterbury, large quantities of water are taken from rivers and groundwater for use as drinking water or for irrigation. Contamination can make the water unfit for these purposes.
Petrol and diesel
Petrol and diesel are hazardous substances that can cause harm to the environment, stock and the health of your family if not stored and used appropriately. If not maintained and checked, storage tanks can leak fuel into the ground, groundwater or waterways. If that happens, drinking water, stock water and water for irrigation is at risk from poisoning.
Storing fuel on your farm is controlled by rules in the Proposed Natural Resources Regional Plan (NRRP). The use and storage of petrol or diesel in above or below ground storage containers is permitted by the NRRP, provided certain conditions are met.
For example, tanks must be situated away from bodies of water and secondary containment may be required. If your tank does not meet the conditions, you will need a resource consent.

You must also be compliant with the Hazardous Substances and New Organisms (HSNO) Act 1996. If you have more than 50 litres of petrol (not including what is in you car) or have an underground storage tank of any size or an above ground tank greater than 5000 litres then you will need find out whether you comply with the HSNO Act requirements for petrol and diesel storage on farms. Visit the ERMA website.
You probably don't need to be an Approved Handler for farm fuel storage and use. However, you must be properly trained on the hazards of petrol, its safe use and handling, and how to manage a spill or other emergency.
Oil
Oil is one of the most common causes of water pollution. Because of the way it spreads in water even a small quantity can cause a lot of harm. One litre of oil can cover 100 m2 of water.
Oil forms a film on the surface of rivers and lakes. This can reduce the level of oxygen in the water, making it difficult for fish to breathe. It can also coat plants and animals that come into contact with it.
Most farms will have small quantities of engine oil stored in sheds. It is important that oil used or stored is managed carefully as mismanagement can cause harm to the environment and human health.
Tips on preventing oil pollution on the farm
- When you drain your engine oil put a drip pan beneath the vehicle or machine’s oil pan.
- Make sure any oil stored around your farm is labelled correctly.
- Store oil on an impermeable surface such as concrete, and store away from drains.
- Check containers regularly to ensure they aren't leaking.
- If you spill oil, stop it from entering drains by absorbing it with sand or sawdust. Never hose it down a drain.
- Clean up spills immediately.
- If you have oil-fired heating, ensure that your oil tank and pipes are properly installed and regularly checked for leaks.
