Tank design approvals

Under the Australian Dangerous Goods Code the design of a tank that forms part of or is used on a tank vehicle must be approved by the competent authority before it can be used to transport dangerous goods.

In NSW the competent authority is the EPA which administers the Dangerous Goods (Road and Rail Transport) Regulation 2014 that sets out requirements regarding tank design approval.

Applying for a tank design approval

To obtain a tank design approval, a tank manufacturer or other company must

1. Complete and submit the application form (DOCX 119KB).

This form must be signed by a reviewing professional engineer, who must

  • have appropriate qualifications at university level
  • have expertise and experience in dangerous goods vehicle design
  • hold or be eligible for membership of Engineers Australia in the occupational category of professional engineer at the member grade

 Complete and attach the compliance report for vacuum tanker (DOCX 85KB), or compliance reports for each applicable Australian Standard

3. Provide the following

  • copies of all relevant specifications, calculations, plans and drawings of the vehicle that show how the tank will form part of or be attached to the vehicle
  • photographs of the vehicle (if already constructed)
  • the plant design registration certificate for pressure vessels
  • the application fee

4. Email the completed form, attachments and application fee to hazardous.materials@epa.nsw.gov.au

If the tank is intended for use outside NSW, the EPA will submit the design to the Competent Authorities Panel for consideration and national approval at its next scheduled meeting.

Once the application has been approved, you will receive a design approval number. This approval number must be included in a compliance plate fixed to the road tank vehicle as required in the ADG Code.

Pressure vessel design approval numbers

A pressure vessel design registration number should not be confused with a vehicle tank approval number.

If the tank is also a pressure vessel (eg LPG tank), the application for design approval must include a pressure vessel registration number issued by SafeWork NSW (or its interstate equivalent) and all associated documentation.
