The NSW Environment Protection Authority (EPA) is working with Tumut Waste Pty Ltd, the operator of Bellettes Landfill, to address alleged odour concerns raised by the community and Snowy Valleys Council.
Since 14 June, the EPA has received multiple reports of rotten egg-like odours in Gilmore and Tumut. These reports followed a power surge that damaged the gas flare system installed at Bellettes Landfill in September 2023. A gas flare system reduces odours by capturing and burning off landfill gases.
After the power surge, Tumut Waste advised the EPA that it had immediately begun repairs and improvements, including a new computer system, the replacement of the power transformer and the installation of a 200-metre gas well, which was completed this week.
Since the initial complaints were received, the EPA has conducted regular odour surveys and site inspections and has reviewed the landfill’s gas management systems. Gas-monitoring equipment has also been deployed at key locations around the landfill.
In July 2023, the EPA responded to odour complaints from the community about the same facility. Complaints had fallen since the installation of the gas flare system.
The EPA is pursuing legal action in relation to the 2023 odour incident, with sentencing in the Land and Environment Court scheduled for December.
EPA officers confirmed the flare was operational during a site inspection on 17 June, 2025, but acknowledged that it could take time for the flare to return to full capacity after a shutdown.
“We are committed to working with the licensee as further works are completed to ensure the flare is operating efficiently,” an EPA spokesperson said.
“The number of complaints from the community has decreased; however, residents experiencing odour impacts at Gilmore or Tumut are encouraged to contact the EPA’s Environment Line. They can email [email protected] with details such as the time, location, duration of odours, and a description of what the odour smells like.
“We acknowledge that these odours can be unpleasant and distressing for the community. Exposure to these odours can result in symptoms such as headaches and nausea. Based on the levels and duration of hydrogen sulphide recorded in the community, ongoing adverse health effects are unlikely.
”If anyone is concerned about the impacts on their health, they should seek medical advice.”
