On the evening of 28 November 2024, Mindarie Regional Council (MRC) received an Environmental Protection Notice (EPN) from the WA Department of Water and Environmental Regulation (DWER) in relation to increased community concern about odours from the Tamala Park site.
MRC welcomes this, and thanks DWER for its guidance and collaboration over the past 18 months on this important issue.
The EPN requires MRC to:
- Develop a plan to manage the significant leachate volumes at the site. This plan must include details of the measures that will be taken to ensure leachate management does not cause odour impacts outside of the premises boundary and odour monitoring to ensure this is the case.
- Provide additional landfill cover over areas of leachate seepage to minimise odour emissions.
- Inspect the final landfill cap and temporary landfill cover across the site, and identify and implement remedial measures to minimise uncontrolled landfill gas emissions.
- Review the existing landfill gas collection and management system to ensure it is working as effectively as possible to maximise the collection of landfill gas.
- Engage a suitable expert to undertake a comprehensive review of the adequacy of the landfill gas collection and management system and identify and implement any improvements necessary to prevent odour impacts outside of the landfill premises.
- Engage a suitable expert to carry out an updated groundwater risk assessment that considers the elevated leachate levels in the site and identifies any actions necessary to mitigate any increased risks to groundwater.
The EPN also allows MRC to install and undertake a pilot-scale trial of a leachate treatment plant. The outcomes of this trial will help inform the longer-term leachate management option of the landfill.
MRC is committed to the management and minimisation of odour impacts on residents living in the suburbs surrounding Tamala Park.
