Test Certificates for Stationary Container Systems

Stationary tanks or process containers are required to have a Stationary Container System Test Certificate. For most tanks and process containers, this is required by 31 March 2007.

What is a Test Certificate for a Stationary Container System?

This Test Certificate is a 'warrant of fitness' that shows the Stationary Container System is safe, properly maintained and compliant with the law. It is different from a Location Test Certificate, and in some instances both may be required.

What is a Stationary Container System?

A Stationary Container System is a stationary tank or process container, together with any associated equipment such as its pipelines and fittings.

When do I need a Test Certificate?

Tanks or process containers holding hazardous liquids or gases above certain quantities require a Test Certificate. It doesn't matter whether the substance is flammable, corrosive, toxic or ecotoxic, or whether the container is above or below ground. If the limits are exceeded, a Stationary Container System Test Certificate is required.

For example, a Test Certificate is required for:

  • any below ground tank of more than 250 litres
  • an above ground tank of more than 2,500 litres holding highly flammable substances such as petrol, solvents or acetone
  • an above ground tank of more than 5,000 litres holding hazardous substances other than those which are highly flammable
  • an above ground tank of more than 500 litres holding a hazardous gas such as LPG or chlorine.

A Test Certificate may also be required when a tank is connected to a burner or stationary internal combustion engine.

Further information on when a Test Certificate is required is given in the ERMA New Zealand Information Sheet Number 29.

How do I get a Test Certificate?

A Test Certificate is issued by a Test Certifier. A register of Test Certifiers is available.

What can be done if I don't comply?

Not all existing tanks or process containers (ie generally those constructed no later than 31 March 2004) may be able to comply with the new requirements. In this case, a Compliance Plan will need to be submitted to ERMA New Zealand. A Test Certifier will advise you on how to do this.

All new tanks or process containers must have a Test Certificate immediately.

What is a Compliance Plan?

A Compliance Plan is an alternative to meeting the legal requirement for existing tanks or process containers. This plan must specify the steps to:

  • upgrade the Stationary Container System to achieve compliance, and the timeframe to do this, or
  • manage the risks of non-compliance.

A Compliance Plan cannot be submitted for any new tank or process container.

See Information Sheet Number 29 for further information on Compliance Plans.

How do I apply for a Compliance Plan?

If your Test Certifier advises a Compliance Plan should be submitted, the Person in Charge must send to ERMA New Zealand a completed 'Application for a Compliance Plan'.
