Stationary container system compliance certificates

A stationary container system is a tank or a process container together with its associated pipe work and fittings normally located in one place. The requirements for a stationary tank are more specific than for a process container.

Follow these three steps to work out if you need a compliance certificate for your stationary container system and how to get one.

  1. What kind of container do I have?
  2. Contact a compliance certifier
  3. Compliance plans

Step 1: What kind of container do I have?

A. Stationary tanks

You must have a stationary container system compliance certificate for your stationary tank if it is:

  • below ground tank (including tanks that are covered by earth or other material) greater than 250 litres
  • above ground tank, greater than 2,500 litres holding highly flammable substances class 3.1A and 3.1B eg petrol or solvents
  • above ground tank, greater than 5,000 litres holding hazardous substances other than class 3.1A or 3.1B eg diesel, caustic soda and corrosives
  • above ground tank, greater than 500 litres holding a gas
  • used with a vapouriser
  • a tank that provides fuel to an oil burning installation which has a service tank and which has a capacity greater than:
    • 500 litres for a class 3.1D substances (eg diesel and waste oil) supplying an internal combustion engine
    • 50 litres for class 3.1A, 3.1B and 3.1C substances (eg petrol) supplying an internal combustion engine
    • 60 litres for class 3.1 flammable substances supplying a burner
  • Go to Step 2

 B. Process containers

You must have a stationary container system compliance certificate for your process container if it is:

  • below ground (including process containers that are covered by earth or other material) of any size
  • above ground, greater than 250 litres and intended for use with a gas
  • above ground, greater than 1,000 litres and intended for use with a hazardous liquid.
  • Go to Step 2

C. Repairs, alterations, relocations and replacements

When a stationary container system which requires a compliance certificate – stationary tank or process container –is repaired, altered, relocated or replaced the compliance certificate may become invalid.

For below ground tanks the compliance certificate may become invalid if there is evidence that the tank is leaking.

If there is a change in service of the tank, the compliance certificate may become invalid.

Check with your compliance certifier if you have any concerns.

 D. You don't need a compliance certificate if the stationary container system...

  • has a total capacity of less than 250 litres, unless it is attached to a burner or a class 3.1A, 3.1B and 3.1C substance supplying an internal combustion engine
  • is a process container under the Pressure Equipment, Cranes and Passenger Ropeways Regulations 1999 and contains flammable substances (Class 2.1.1, 3.1A, 3.1B or 3.1C); and is constructed of fire-resistant material
  • contains only a solid
  • contains only toxic substances with hazard classes 6.1E, 6.3A, 6.3B or 6.4A or combination of these
  • is an integral part of a refrigeration unit or
  • is a tank containing liquefied petroleum gas (LPG).

 

Even if a stationary container system does not require a compliance certificate, it still needs to meet certain legal requirements. Contact a compliance certifier(external link), or WorkSafe New Zealand, to find out what these requirements are.

Step 2: Contact a compliance certifier

You will need to contact a compliance certifier to get a stationary container system compliance certificate. Contact a compliance certifier(external link) in your area who is able to issue stationary container system compliance certificates.

Step 3: Compliance plans

What is a compliance plan?

Tanks and process containers constructed before 1 July 2006 may not comply with the requirements for a compliance certificate under the Health and Safety at Work (Hazardous Substances) Regulations 2017.

In order to achieve compliance it is possible to apply for a compliance plan. A compliance plan allows you to either upgrade your stationary container system or manage the risks of non-compliance with alternative controls.

A compliance certifier can help you work out whether you need a compliance plan for your stationary container system and how to get it.

The compliance plan is not an approval for a stationary container system. It is used to get a stationary container system compliance certificate.

As compliance plans are applicable to stationary container systems constructed prior to 1 July 2006 they are not applicable to those constructed from 1 July 2006.

A. Have your stationary tank or process container assessed

A compliance certifier will examine your stationary container system and identify anything that doesn’t comply with the Health and Safety at Work (Hazardous Substances) Regulations 2017. 

The compliance certifier provides a report on the system, including how well the system has been maintained and repaired in accordance with its original design standard if known.

B. Apply for a compliance plan

Once the compliance certifier has examined and reported on the stationary container system, an application for a compliance plan may be made.

You, or the compliance certifier, complete the application below.
