Underground Petroleum Storage System Self Assessment Form

Are you up to date with your obligations?

Leaks from underground petroleum storage systems (UPSS) are a major environmental problem and can have impacts that are costly and time consuming to fix. For these reasons minimum requirements for UPSS construction and operation were introduced in 2008 and are known as the UPSS Regulation.

This self-evaluation has been developed to provide service station operators with a quick and simple way to review their compliance with environmental requirements for UPSS in NSW.

Why should you participate?

Service station operators who participate in this program are more likely to identify shortcomings and take the necessary actions to correct them before they develop into major environmental issues. Tamworth Regional Council encourages all service station operators to participate in this program. Council will work with those operators who participate in this self-evaluation program to help bring them into compliance with the requirements.

Who should complete this self-evaluation?

This self-evaluation should be completed by the company or person who has primary responsibility for managing and maintaining the UPSS at your service station (known as the ‘person responsible’). In some cases, this can be a person other than the service station operator or owner. This should also be completed by land holders who have a UPSS on site that is no longer actively used.

How should this self-evaluation be completed?

This self-evaluation form is a series of short questions. Please answer all questions to the best of your knowledge. Please insert additional comments or details where required. 

This self-evaluation should take 5 to 15 minutes to complete.

What if you operate multiple sites?

If you operate multiple service stations in NSW, you should complete one form per site. 

Next steps

Please take note of any answers that indicate ‘Action needed’ and take steps to implement the specified improvements. If you are unsure about which actions to take, the organisations and further information below can assist. You can also contact Tamworth Regional council on trc@tamworth.nsw.gov.au for advice and assistance.

Please note that Council may undertake follow-up action to verify the answers provided in this survey. Therefore, it is important that you have answered them as accurately as possible.




Complete one per each underground storage tank


This part only applies to UPSS installed or significantly modified after 1 June 2008 (including any tanks or piping that have been modified or replaced since 1 June 2008).

If you only have tanks and piping that have been installed before 1 June 2008, please go to Part 3.

Ensure all ‘new’ UPSS have the four items of mandatory pollution protection equipment listed in 1a-d.

Answer all 4 questions for UPSS installed or significantly modified after 1 June 2008 (including any tanks or piping that have been modified or replaced since 1 June 2008). 

Action needed if 'No' is answered to any of the following 4 questions.

1. Are they constructed of non-corrodible materiel (e.g. fibreglass)?* - required
Do they have secondary containment (e.g. are they double walled)?* - required
Do they have overfill protection devices?* - required
Did they pass integrity (tightness) test at the time of commissioning?* - required


2. Is there a loss monitoring procedure in place at the site to measure discrepancies between the amount of petroleum that should be in the system and the actual amount present?* - required
3. Does the loss monitoring procedure generate a report monthly (as a minimum)?* - required
4. Are all records relating to the loss monitoring procedure retained on site or in a readily accessible location?* - required


5. All UPSS sites are required to have a secondary leak detection system. At least three groundwater monitoring wells (GMWs) are preferred. Does your site have a network of GMWs to help detect UPSS leaks?* - required
6. Do you have an alternative system for secondary leak detection?
7. Which alternative system/s is/are used for secondary leak detection of the UPSS?
8. Was/were the alternative system/s for secondary leak detection designed and installed by a duly qualified person?
9. Do you ensure groundwater is sampled from the GMWs and tested at least every six months?
10. Are all records relating to the secondary leak detection system (e.g. well installation reports, testing procedures and six monthly groundwater monitoring reports) retained on site or in a readily accessible location?


11. Do you have a Fuel System Operation Plan (FSOP) or an equivalent document with information about your UPSS
12. Does the FSOP contain the following documents and information about the design, construction, operation and maintenance of the UPSS?
A fuel loss monitoring procedure
An incident management procedure
A maintenance schedule
Current ‘as built’ drawings of the UPSS and site plans
A copy of the specifications and/or industry standards used in the design and construction of the UPSS
The name, address and 24 hour contact phone number of the ‘person responsible’ for the UPSS
The access details for the site, including details of locks, gates and fences
Copies of records relating to loss monitoring and groundwater monitoring at the site?
13. Have any tanks at the site been out of use for more than two years?
14. Has a UPSS previously been decommissioned at the site?
15. Has a decommissioning validation report been provided to your local Council for any decommissioned tanks?
