New Report Labels Coal Ash Dumps a 'Ticking Time Bomb'


BY LILLY HAINES 

New research released today claims communities in Lake Macquarie and the Hunter situated near coal fired power stations are at serious risk from poorly managed coal ash waste sites.

The report titled Unearthing Australia's Toxic Coal Ash Legacy published by Environmental Justice Australia (EJA) is the first comprehensive national study of coal ash waste management in Australia.

Coal ash is a toxic by-product of coal fired power containing heavy metals including mercury, lead, arsenic, selenium and chromium which can have adverse effects on human and environmental health in nearby areas.  

Report author and EJA Lawyer Bronya Lipski says communities closest to coal fired power stations bear the greatest burden with most sites being extremely close to waterways.

"Lax government regulation and poor management has led to the contamination of groundwater, rivers, lakes, and aquatic ecosystems as well as toxic air pollution from dried out lumps," Ms Lipski said.

Eraring, Vales Point, Liddell and Bayswater Power Stations have all been named in the report as poorly managed ash dump sites with each of the stations described as inadequately lined to prevent groundwater contamination.

The report says most of Australia’s coal ash dumps are unlined meaning groundwater is not properly protected from toxic waste.

"Independent water testing has shown there are higher levels of really toxic contaminants in Lake Macquarie to the point where certain fish and crabs can only be consumed in small amounts compared to other fish and crabs," Ms Lipski said.

Water sampling done earlier this year by the Hunter Community Environment Centre (HCEC) found the creek that takes overflow from the Eraring as dump site has a selenium concentration more than 55 times the level recommended to protect fish and birds.

"Coal ash dumps are a ticking time bomb. All Australian governments need to act now, not wait for disaster," Ms Lipski said. 

She says communities haven't been properly informed about the potential risks and is calling for state parliamentary inquiries into the issue.

"That kind of process is going to make sure that there is a transparency of information and that operators and regulators can be preparing now for rehabilitation and closure plans well before the power stations close," Ms Lipsky.

Company Secretary of Vales Point operator Delta Electricity, Steve Gurney, questions the scientific validity of the water sampling undertaken by the HCEC cited in the report.

"EJA is a group of anti-coal activists with one state of objection and that is to shut down coal fired power stations and this is another attempt from them to sensationalise the issue to create uncertainty and community fear regarding the operation of power generators," Mr Gurney said. 

Delta says all their testing results have to be undertaken using approved environment protection authority (EPA) guidelines and those results are published monthly on their website.

“The current conditions set by the EPA are very stringent and all the testing shows results well below the international guidelines for fresh and marine environments.

“Testing undertaken on a regular basis shows there is no leeching from these ash dams. Power stations and particularly ash dams are highly regulated with significant oversight by the EPA,” Mr Gurney said.

Manning Park resident Sue Wynn has lived within 2km of the Vales Point power station for over forty years and drives past the ash dam every day.

Ms Wynn says she is concerned about the environmental "devastation" the ash dam has caused in Lake Macquarie.

"That has really affected my life here in that sense because I know that environmental devastation is on my doorstep, and it also has an effect because we want to know that that is safe for our health.

"Because these power stations were built in the 60s, the ash dams were put in and they were unlined, the government did not bring in any stricter environmental pollution control when they had the opportunity to so that sludge is more toxic than it needs to be. 

"We still have 1960s air pollution controls on that power station," Ms Wynn said.

The EJA report recommends state inquiries into coal ash dumps, rehabilitation plans, tougher groundwater regulation, safe containment of existing ash dumps, bond payments to protect communities, national guidelines, and more transparent easily-accessible information on the issue.
