At the February Power & Pollution Summit, Bronya Lipski (Environmental Justice Australia) revealed that a comparison of licenses undertaken on operational and coal-ash remediation showed Australia is decades behind international standards and is exceptionally poorly regulated. This has resulted in short and long-term health impacts which are responsible for 300 death/year.
Lisa Evans from the USA-based Earth Justice shared the American experience where in 2008 an ash dam breach contaminated a 121ha river system, including high value waterfront properties, and killed more than 40 people who were involved in the clean-up relocating the toxic sludge (they were discouraged from wearing adequate PPE so as not to alarm people of the danger).
This event triggered a reform on the safe operation of coal-ash dumps in the USA which included:
- Groundwater monitoring for all contaminants at the boundary of the ash dam & public access to data
- Stringent limits on toxic pollutants in groundwater
- Closure of all unlined wet coal ash basins
- Groundwater restoration when contamination limits were exceeded
- Engineering controls and siting restrictions for ash-dams
- Structural stability standards
- Safe closure of all coal-ash dumps, with monitoring for 30 years including corrective measures for breaches
- Financial assurance for clean-up on closure
The CPPA made a submission to the inquiry into the costs for remediation of sites containing coal ash repositories and was been invited to give evidence at a hearing on 27/3/20, but it has been POSTPONED.
