What is a stationary container system?
A Stationary Container System is a stationary tank or process container and its associated equipment, pipe work and fittings, up to and including all transfer points. This includes the valves, vaporisers, oil burners, dispensers and fire fighting systems.
A Stationary Container Test Certificate is different to a Location Test Certificate and in some instances both will be required. The Location Test Certificate is for places where flammable or oxidising substances are stored. The Stationary Container system controls apply to all hazardous substances – flammables (including diesel), toxics, corrosives and ecotoxic substances.
What is a Stationary Container System Test Certificate?
Test Certification is a verification against the legal requirements specified in the Transfer Notice*. This certification is required for all stationary container systems as below and which contain a hazardous substance of any hazard classification:
All below ground storage tanks or process containers with a capacity of more than 250 litres.
All above ground storage tanks with a capacity of more than:
- 2,500 litres and which contain or are intended to be contain a substance of class 3.1A (e.g. petrol) or 3.1B (e.g. acetone, iso-propanol, solvents);
- 5,000 litres and contains or is intended to contain a hazardous liquid of any other classification (e.g. diesel, toxic, corrosive or ecotoxic substance);
- 500 litres water capacity containing a hazardous gas (e.g. LPG, oxygen, chlorine.)
- Tanks connected to a burner or a stationary internal combustion engine and which have a capacity of more than:
- 50 litres containing a class 3.1A, B or C hazardous substance supplying an internal combustion engine;
- 500 litres containing a class 3.1D substance supplying an internal combustion engine (includes diesel);
- 60 litres containing a class 3.1 substance supplying a burner.
- A stationary container system that includes a direct fired vaporiser.
- All above ground process containers:
- Over 250 litres water capacity that contain a hazardous gas;
- Over 1000 litres capacity that contain a hazardous liquid.
- (Process containers which are constructed of fire resistant material, which contain class 2.1.1, 3.1A, 3.1B or 3.1C hazardous substances and which are required to comply with the Health and Safety in Employment (Pressure Equipment, Cranes and Passenger Ropeways) Regulations are excluded.)
The certification of Stationary Container Systems is done by a Test Certifier approved to issue test certificates for Stationary Container Systems. A register of Test Certifiers is available from the ERMA New Zealand website .
If the Stationary Container System fully meets the requirements of the Transfer Notice, the Test Certifier will issue a Stationary Container System Test Certificate. If the Stationary Container System does not fully meet the requirements of the Transfer Notice, the Person in Charge will need to apply to ERMA New Zealand for approval of a Compliance Plan.
See ‘What is a Compliance Plan’ below.

What is a Secondary Containment System?
A Secondary Containment System means a system in which substances (in liquid form) will be contained if they escape from the container where they are being held. The most common form of Secondary Containment System for above ground stationary containers is a compound (bund).
In some circumstances this secondary containment system may not be in full compliance with the law*; for example, with a below ground stationary tank that has been installed without secondary containment it may be impractical to achieve compliance until such time as the tank is replaced. If this is the case, a Compliance Plan may be appropriate.
Compliance plans may be submitted only for those secondary containment systems associated with a stationary containment system e.g. where the storage of drums requires a secondary containment system, a compliance plan is not able to be submitted.
*Regulation 39 (or Regulation 40 in the case of a below ground stationary tank) of the Hazardous Substances (Emergency Management) Regulations 2001 and Part 1 of Schedule 9, of the Hazardous Substances (Dangerous Goods and Scheduled Toxic Substances) Transfer Notice 2004 (as amended)
What is a Compliance Plan?
The Person in Charge of a stationary container system that was in use before 31 March 2004 may apply for approval of a Compliance Plan as an alternative to meeting the requirements of the Transfer Notice.
This Compliance Plan is a plan that specifies the steps that the Person in Charge must take to either:
- make whatever alterations to the system that are necessary to enable compliance with the Transfer Notice; and/or
- manage the risks of non-compliance
All new Stationary Container Systems and their associated Secondary Containment Systems that came into service since 1 April 2004 must meet the current legal requirements.
