Port Augusta Power Stations Site (Flinders Power)
Regulation of closure
On 9 May 2016, power generating operations at the Port Augusta Power Stations site ceased.
The Port Augusta Power Stations site is regulated by the EPA under the Environment Protection Act 1993 for several activities of environmental significance. A condition of licence requires Flinders Power to develop a closure plan to address environmental considerations at the site. This includes, but is not limited to:
- decommissioning and decontamination of coal burning equipment;
- removal of coal from the coal stockpile and other coal handling areas;
- ash dam rehabilitation;
- assessment and removal of chemicals and hazardous materials;
- removal of waste including appropriate disposal of asbestos.
Flinders Power are required to meet specified actions, timeframes and milestones in regards to each of the above environmental considerations.
To minimise potential dust nuisance impacts to the community, consideration of dust management measures is also required.
To address site contamination investigation and assessment, the EPA has entered into a Voluntary Site Contamination Assessment Proposal with Flinders Power.
Regulation of dust events
Following community concern about dust emissions from the Ash Dam in August 2016, the EPA is taking the following mitigating actions:
- Increasing EPA presence in Port Augusta through inspections and engagement with local council.
- Ensuring Flinders Power has an approved Dust Management Plan with controls reflective of the changed site conditions, and verifying that Flinders Power complies with the plan.
- Analysing historical data to determine seasonal trends and baseline data to better understand regional conditions.
- Installation of EPA air quality monitoring equipment adjacent to the ash dams to collect samples and ascertain the composition of the dust.
- Liaising with SA Health on dust events and monitoring approach.
- Ensuring Flinders Power advises the EPA of any future actions, trials or closure activity that may require amendments to current dust management controls.
