Underground petroleum storage systems

Underground petroleum storage systems are commonly found in places where fuel is stored or used such as service stations. Leaks from underground petroleum storage systems can contaminate soil and groundwater. Clean-up can be costly, complex and time consuming.

The Regulation that governs how these underground tanks are managed is being updated, and the NSW Environment Protection Authority (EPA) is seeking the views of the community and industry on the proposed changes.

The current Protection of the Environment Operations (Underground Petroleum Storage Systems) Regulation 2014 sets minimum standards for the design, operation, maintenance and monitoring of underground petroleum storage systems. These standards aim to ensure leaks are prevented, or if they do occur, they are detected and fixed early.

Consultation has now closed

Consultation on changes to the Protection of the Environment Operations (Underground Petroleum Storage Systems) Regulation 2019 was open from 17 May 2019 to 14 June 2019. Consultation has now closed.

The EPA is currently reviewing submissions received from the consultation and is finalising the proposed Regulation.

The proposed Regulation

The proposed Protection of the Environment Operations (Underground Petroleum Storage Systems) Regulation 2019 requires operators to report on and fix leaks quickly and implement industry best practice at their sites.

The proposed Regulation seeks to:

  • improve the clarity of requirements
  • align regulatory requirements with modern, industry best practice
  • require advance notification to a local council of decommissioning
  • require an annual report on the fuel system to be provided to the appropriate regulatory authority.

The proposed Regulation and the accompanying Regulatory Impact Statement are available for download from the document library to the right. You can learn more about the proposed Regulation in the FAQs to the right.
