Sydney Park was formerly the site of major landfill and brickmaking.
Monitoring gas levels is normal practice in managing historic landfill sites nationally and overseas.
Methane is a by-product of organic materials such as food and garden waste when it decomposes.
Testing showed elevated concentrations of methane and carbon dioxide inside the park and along its perimeter. Elevated readings of methane are reported to the Environment Protection Authority.
The Environment Protection Authority has declared the park as a contaminated site under the Contaminated Land Management Act. The park and some surrounding roads and footpaths have been included in the declared area and will be part of the regular, ongoing monitoring program we undertake.
We lodged a voluntary management proposal in November 2019. It outlines further investigations into better monitoring and control of landfill gasses at the site. The authority approved our lodgement in January 2020 and we are now managing the site in line with this voluntary management proposal.
- The City of Sydney has engaged an environmental consultant to undertake additional testing and monitoring at, and adjacent to Sydney Park. During this time you can continue to use the park as normal.
- You can continue to use the park as normal. Exposure to methane is considered low risk in open spaces such as parks, as it dissipates and can't concentrate.
- We regularly monitor Sydney Park, and confined spaces nearby. Fire and Rescue NSW conducted testing of surrounding residential and business properties in November 2018, and all buildings were declared safe.
- If elevated levels of methane are detected at any time, we will notify the Environment Protection Authority.
We are developing long term solutions and strategies, in consultation with the appointed environmental consultant.
